Offensive MVP: Alex Mack – Sure, Matt Ryan is that guy and no one debates that. Still, it was the acquisition of Mack that changed the dynamic for the entire offense. After a season where three different centers combined to struggle even snapping the ball, Mack entered to not just settle the position down, but to have a Pro-Bowl year on dominance at the spot. Mack’s knowledge of Kyle Shanahan’s system and his ability to get to next-level blocks paved the way for a record-smashing offense. There were lots of record-breaking performances in the offensive stats this season, but it’s possible none of them would have occurred without Mack in the middle.
Defensive MVP: Vic Beasley – This was an obvious choice, but the least obvious pick at the start of the season. Coming out of camp there was concern he would not break out into stardom. That concern is gone now. NFL leader in sacks (15.5) and forced fumbles (6), No. 44 burst onto the scene in a Pro-Bowl season where he placed his name into consideration for the NFL’s Defensive Player Of The Year talk. No one, and I mean NO ONE, had that heading into the opener.
Special Teams MVP: Matt Bryant – Bryant’s resume consisted of 34 field goals, 56 extra points and even a couple of emergency punts in 2016. Bryant was awarded NFC Special Teams Player of the Week and was voted to his first ever Pro Bowl at age 41. A year after there was serious concern that his career might end because of an injury, he bounced back to have the best season of his life.
Position Coach of the Year: Raheem Morris — The Falcons sought a new receiver’s coach this past offseason. Unable to find the right fit they asked their assistant head coach to take over. Morris had a head start with Julio Jones and a veteran free agent in Mohamed Sanu, but depth was a question – a question answered so loudly that a record-smashing offensive season never broke stride even with the two players mentioned above sitting on the sidelines watching. Taylor Gabriel, dumped by Cleveland, shot to stardom. Justin Hardy, Aldrick Robinson and Nick Williams all had to contribute. And when called on, all more than just filled a spot, they flourished. No doubt that Wade Hardman (Tight Ends) and Jeff Ulbrich (Linebackers) were challenged by injuries and depth and did fabulous jobs, but no position changed the season for this club quite like wideout.

Certainly, VR has an appeal for consumers and a use case for entertainment content creation, though the most promising markets for VR is in engineering, design, and AEC. While it may seem that VR has inspired new applications, there is a long history of development behind professional visualization that is being enriched by real-time rendering technology and game development tools. VR is another enhancement for the display, replacing CAVEs or flat PC screens.
Putting CAD models to work in digital environments can be labor-intensive and has fallen to specialists who have figured out their own ways to condition models – reduce them to the visible essential data needed and export them into the desired software for further work, such as animation, rendering, content authoring, and so on.
The renewed fascination around interactive 3D, thanks to the game industry and VR, has created new users and developers. And over the last 10 years or so, a younger generation has grabbed the tools of the game industry to create content. And in 2017, the industry has seen the arrival of new tools to link the world of CAD with the tools of content creation.
Epic, maker of the Unreal Engine, announced its acquisition of Datasmith at SIGGRAPH 2017. The tool was originally introduced at SIGGRAPH 2016 as MUS (Motiva Unreal Scene). Datasmith enables structured transfers of necessary data from CAD models to game engines, where the data can be used in content creation. It supports 20 CAD and digital content creation sources, as well as modeling and animation tools such as Autodesk 3ds Max.
As an interesting side note, the Datasmith effort is being led by former Autodesk director Ken Pimentel, who has a good deal of experience in professional visualization and animation.
Last summer, Epic announced plans to offer the Datasmith toolbox through a private beta program. Epic has been saying that the ability to work in real time with rendering is the game changer for game engines, but without good ways to get and manage content, the game never really gets started.
At Autodesk University late last year – where the Unreal team pitched its engine for use with CAD data in manufacturing, AEC, and content creation – Marc Petit, general manager of Unreal Engine Enterprise at Epic Games, told the audience that Unreal customers want real time in every aspect of content creation. “They don’t just want [Chaos Group’s] V-Ray in real time, they want everything: the physics, the materials…
everything.” And, that means dealing with lots of data – but only the necessary data.
Petit added they have also found that customers don’t want to pay for services to get the data into Unreal Engine. “That’s why we bought Datasmith,” he said.
Unreal has also been able to incorporate Alembic into its pipeline to deal with assets from 3D animation.
Datasmith helps users import models with all the necessary components – including assembly components, surfaces, materials, physics, and animations – into Unreal Engine, with assets organized in a way the application understands and users can see and understand.
The dirty little secret about transferring CAD models for use in other applications is that it’s difficult. How difficult depends on the applications, their friendliness to each other, and the complexity of the data.
Autodesk bought Kaydara back in 2006. The company had a real-time, online content creation suite called Filmbox, which used the FBX format for data exchange between modules and outside applications, including Autodesk’s. Autodesk has since fine-tuned FBX for easy data transfer.
In addition, Autodesk bought Bitsquid for its game engine. Renamed Stingray, Bitsquid was added to Autodesk’s growing arsenal of game development tools. Unfortunately, Autodesk’s timing was not great, nor was its implementation. Autodesk seemed uncertain about whether to support Stingray as a product to develop applications using content created in its tools, or to plunder the technology for its products Max, Maya, and Flame.
The interconnection with the CAD world didn’t fully materialize, either. Autodesk introduced Project Expo as a tool to transfer Revit files to Stingray, but it seems to have foundered early.
In the end, Autodesk announced that Stingray would be shut down. The company said customers were looking to Unity and Unreal to develop interactive applications. One of the arguments Autodesk made on its website is that the commercial engines are being continuously enhanced for customers and are adapting to changing markets. The implication being that Autodesk could not keep up the same level of updates for markets that were not critical to Autodesk.
In October 2017, Autodesk and Unity announced a strategic partnership to more easily enable data exchange of content created in Autodesk’s tools.
But, what about Epic? Epic claims that early beta participants working with Datasmith rather than FBX have seen productivity gains of up to 70 percent, and that Datasmith enables them to work with a high-fidelity scene in Unreal Engine that is visually consistent with what they are trying to achieve in the finished product.
Also at SIGGRAPH last year, Lightworks announced a new product called Slipstream, which isn’t so much a product as a service bundle, to address the same sorts of problems being addressed by Datasmith.
The Lightworks crew has a long history of providing integrated rendering within design and engineering products from Autodesk, PTC, IMSI, Dassault, Siemens, and so on. According to Lightworks’ David Forrester, the demand for rendering has accelerated thanks to increased interest in virtual reality and the increasing usability of game engines for non-gaming content. Game engines let customers get all their assets in one environment, where they can be “directed.”
Today, Lightworks uses the Nvidia Iray technology as the rendering end of its system. And, as a longtime provider of rendering back ends – its own, and now Iray – the company has integrated rendering in multiple PLM products. It did some of its early development work for Slipstream with Siemens, which uses Lightworks Iray in its CAD programs. Lightstream understands CAD pipelines and the complexities inherent in CAD models. What Lightworks wants to do, says Forrester, is help its customers streamline the data to get a “visual BOM” (bill of materials).
Lightworks has approached the creation of Slipstream as a service plus technology, depending on the end use requirements and the types of models. At the end of the process, customers then have an easy-to-use recipe for getting models out of CAD and into a game engine. Forrester says that once they have helped a company create a Slipstream
pipeline, it often inspires the customer to come back for different end uses in VR, AR, and rendering.
The beauty of Slipstream, says Lightworks CTO David Hutchinson, is that companies can work with their own intellectual property, without having to send it off to an agency to create a visualization or application, and they retain the ability to change up the work, redo, and repeat.
Foundry’s Project Bunsen
Foundry found out a lot about the complexity of CAD data with its acquisition of Luxology in 2012. Luxology had been trying to expand its market for its modeling and animation tools by offering visualization tools to designers.
After the Foundry acquisition, the company took a look at the challenge by adding its own understanding of pipeline development. From its work in compositing, special effects, asset management, rendering, and even AR/VR content development, Foundry has created Project Bunsen, developed originally for the AEC industry – which, again, wants to have a way for people to understand buildings and other projects.
However, the amazing thing about the current times we’re living through is that even as companies work on developing products, the requirements coming from customers are shifting with advancing capabilities. Bunsen is seen as a tool for all types of design and engineering customers who might want to create a visualization, and even as the end purpose for the visualizations might be changing, the basic requirements are pretty simple.
The process of getting data out of CAD and into a creative platform requires the data to be simplified and delivered in a structured way. The process has to be scalable and repeatable. Foundry uses the cloud to process data and ensure scalability.
As people try to use CAD models, they’re always faced with translating the data into usable forms by other software programs. There have been plenty of translators developed for this purpose, and usually they are used in conjunction with other tools to help move the data along the pipeline.
Tools like Datasmith, Slipstream, and Project Bunsen are actually the culmination of work that’s been going on for a long time to try and make the system of design to visualization easier and more predictable. The general-purpose use of game engines has become one more very useful tool because game engines enable artists and developers to work within a visual environment to create interactive content.
If VR and AR were to go away – which no, no, they’re not! – there would still be a need for these tools, and as a result of their existence now, CAD models are going to become more widely used in marketing, entertainment, sales, virtual design...
you name it.

By Mick Buckland
With a stunning 8-0 victory at home to Alrewas A, it is Ivanhoe A who have taken over at the top of the David Wain Insurance Premier Division. They now lead at the top by 2 after wins for Andy Marriott, Dan Blunn, James Hastie and Ant Moore saw off an Alrewas side that only the week before held previous leaders Burton Cons A. Andy had his regular 30+ contribution whilst Ant Moore was top scorer on the night with a nice 37.
Burton Cons A won again but were 6-0 up before an inspired Simon Mansfield for Swad Cons A beat a struggling Jon Swift to make the score more respectable at 6-2. Earlier John Shilton avenged his defeat to Andy Grainger in this year’s Evershed with a 2-0 win, including a nice 62 clearance. Mike Buckland comfortably won the first against former darts pro Mark Robinson making his debut but Mark dug in to make the second much closer before Buckland mopped up the last few colours and the win. Darren Coady struggled at the start of both frames against a determined Paul Slater but in the end Darren included a lovely 51 to eventually win both with something to spare. the Cons are still unbeaten but like in second with one match before the Xmas break.
The week’s big clash saw Belmont A get past Burton Cons B by a similar 6-2 scoreline. Two victories for the Chambers brothers, Rob and John, made the difference as they defeated Simon Smith and Owen Jones-Rob rolling in contributions of 30 and 32. The other two matches were halved-Josh Gebbie with Jon Fletcher and Ian Archer with Matt Milnes in two close frames. This leaves Belmont 2 points ahead of their rivals in third and only six points off the top.
Tutbury A have hit the bottom of the table after being beaten 6-2 at home by Spot On B. Steve Mabbutt had the highest effort of the night with a 38 against Simon Tarrant who hung on well for a draw. Steve Butterworth, for Spot On, rolled a nice 36 in during his win over John Brentnall and Steve Lane played nicely to score a good win over Chris Mabbutt. The game between Steve Hathaway and Loz Kennerson was halved – back to back wins for The Spots have pulled them 3 clear of the drop zone.
Spot On A made it a brace of wins for the club but they are still third from bottom. Last week they defeated Tutbury B 6-2 with wins for Andy Speirs, who had a nice 33, and Mark Stirling. Ade Harper and Wayne Pereira drew as did Tom Elliott and Andy Thompson.The Tutters have now lost 4 from their last 5 and although are in halfway, they are only 3 above last week’s opponents, who are in the drop zone.
At Swad Snooker Centre there was the first Premier division derby for a few years as the club’s A side narrowly beat the B team. Harry Farrell was man of the match as he had a 59 in his win over John Davis but he landed on the losing side. Rich Hinks scored a good draw with Andy Goldingay but that was as good as it got for the B as wins for Chris Dewy and Steve Ayre saw the A team home. Both sides look to have done enough already to stay in the division next year as they both sit mid table.
At the top of the PJM Fascias Division One, Tutbury C made it three wins on the bounce and in the process ended the unbeaten record of Belmont B. Steve Butler made the difference on the night as he had some nice contributions in his win over Mark Vaughan. the other 3 ties were halved….Wayne Smith with Graham Bailey, Steve Burrows with Mick Morris and Tom Lucas with Zaheer Hussein. This leaves Tutbury three points clear at the top but more importantly 10 above 4th place when looking for promotion. Belmont slip to 5th and are without in win in four.
Second placed Ivanhoe B were only able to manage a draw away at Alrewas B. Dave Trueman for Alrewas would normally have won a frame with a 28 included but Stu Tagg held on well for the win for Ivanhoe. For the Legionnaires, Carl Poulton returned to form by beating the in form Bren Mattley. Ian Hiley and Mick Kirk played out a deserved draw, as did the two Adams, Walton and Pickering. Ivanhoe are still looking good for an immediate return to the top flight whilst Alrewas are just about hanging in there in the promotion race.
Stapenhill A beat Ivanhoe C by a 5-3 scoreline. There were wins for Andy gretton and Dave Shenton over Graham Measures and Darren Wilson respectively. A draw was the result in the game between Callum Coleman and Steve Cockeram whilst Gaz Dolam was on form for the Ashby side in his win over Chris Sheldrake. In a tight division, both sides are just above the relegation zone and will look towards better second halves to the season.
Burton Cons C are in the drop zone despite having a 5-0-5 record. Last week they were undone 6-2 at home by Woodville A who have finally pulled themselves away from trouble. Yet again Wayne Brewin was the starman including a 38 on the way to beating Greg Read. Mark Satchwell and John Chambers also notched up wins whilst Tom Egginton replied for the Cons with a nice victory over Bob McInulty.
Newhall A made it 5 league wins on the bounce and on the move towards the promotion places after a slow start to the season. Adam McInulty was the man of the match rolling in a nice 47 and beating the SDSC C talisman Nick Harcombe in the process. The two Martins, Hurdman and Hicks were also on form to score wins whilst there was a draw between Newhall’s John Fich and Ray Bancroft of Swad Snooker Centre. Newhall are now just 3 points off a promotion spot with a game in hand, whilst SDSC C are getting cut off at the the bottom, 18 points from safety.
In the Newton Fallowell Division Two, Stapenhill B cemented themselves into one of the promotion spots with a 5-3 win over Ivanhoe D. Greg Britton was on form as he secured a win for the extra bonus point after defeating Adam Briggs. the other three ties were halved-Brain Lowrie and Simon Piechowicz, Leo Worsley and Andy Tomlinson and Matt Tewkesbury with Bryan Sharratt.
Spot On E also look good for promotion as they got back to winning ways with a 7-1 demolition of Belmont D. The Servicemen’s Andy Biggadike mad the best break of the evening scoring Belmont their solitary point with a nice 36 in his draw with Ben Menzies. Otherwise it was plain sailing for The Spots with wins for Jared Cronje, Jordan watts and Brad Williams.
In the match between Burton Cons C and Woodville B , it was the Cons that went flying into a 3-1 lead at half way. Jim Jennings was knocking the ball in from all angles including a nice 26 in his first versus Billy Bob Brooks. Brooks should probably have won the second but left Jim on for the pink which he gratefully accepted. Alan Orpwood and Al Munnien shared their two frames in a match neither player deserved to lose. Tony Coleman rolled the Worriers back into the match taking both against Paul Brooks who had no run at all in the second leading to him conceding with two reds on. The final match between Pat “Pizza Boy” Ryan and Ian Protheroe, it was Ian who took the first with a nice pink and black. The Pizza Boy responded in the second, knocking in some cracking long pots to leave the score a deserved draw.
Rolleston B and Swad Cons C had a tight match but it was The Rollers who came out 5-3 winners. Only one individual winner on the night and that was Kev Norris in the last match. There were earlier drawn matches between Rob Sanders and Andy Boam, Rob Tubey and Bob Birch and Lionel Lewis and Mark Brookes.
Terry Bosworth was man of the match in the match between the C teams of Belmont and Rolleston. He rolled back the years and knocked in a lovely 35 on his way to victory over Aaron Doyle. Brain Cutting and Dave Press were also on target for The Servicemen, whilst Steve Atkin returned two frames for The Rollers in his win over Graeme Drayton.
Although not yet winning this season, the Snookerettes are getting difficult to beat and last week they held Woodville C on their own patch. Kate Stirling provided the highlight for the girls of Spot On D as she beat Mark Gallagher. For Woodville, Denis Moore beat Marie Brides whilst there were draws between Jim Marcer and Gilda Horvath and then Wayne Allen and Clare Peaty.

Are changes in pain induced by myofeedback training related to changes in muscle activation patterns in patients with work-related myalgia?
Journal article, 2006
The objective of this explorative study was to investigate to what extent changes in perceived pain, induced by myofeedback training, are correlated to changes in muscle activation patterns. Thirty subjects with work-related myalgia received myofeedback training. Before (T0), directly after (T1) and 4 weeks or, in a subset of patients, 3 months after (T2) this training, surface electromyography (sEMG) measurements of the upper trapezius muscle were performed during standardized computer tasks; a typing and a stress task. Besides this, visual analogue scales (VAS) were filled in to assess the levels of pain in the neck and shoulders. From the sEMG, root mean square (RMS) and relative rest time (RRT, i.e. the percentage of time RMS is below a certain threshold) were used for data analysis. The relationships between RRT, RMS and VAS at T0 as well as for the changes between T1-T0 and T2- T0 were investigated using Spearman correlation coefficients. The results revealed no significant correlations between VAS and RMS both at baseline (range R = -0.22 to 0.17) and for the observed changes (range R = -0.33 to 0.32). Also, for VAS and RRT, low correlations were found for baseline (range R = -0.27 to 0.21) and for changes between T1-T0 (range R = -0.02 to 0.38). However, for the changes between T2-T0, correlation coefficients for the VAS for the shoulder and the RRT of the right trapezius during both the typing and stress tasks were significant at the P = 0.05 level, whereas the correlation coefficients for the VAS for the neck and both the left and right trapezii during the stress task approached significance (P = 0.05 and P = 0.1, respectively). These results suggest that decreases in pain observed at long term follow up after myofeedback training might occur as a result of an increased ability to relax but not as a result of decreased muscle activation level. However, the largest correlation found was 0.6. This means that the maximal explained variance (R2) is low (36%), and that there are also other processes than the changes in muscle activation that contribute to changes in perceived pain.

For fans of The Queen's Gambit, this is the real life story of a female chess champion travelling the world to compete in a male-dominated sport with the most famous players of all time.
Jennifer Shahade, a two-time US Women's Chess Champion, spent her teens and twenties travelling the world playing chess. Tournaments have taken her from Istanbul to Moscow, and introduced her to players from Zambia to China. In this ultra male-dominated sport, Jennifer found shocking sexism, but she also found friendships, feminism and hope.
Through her own story as well as interviews with international players, Jennifer invites us into the extremely competitive world of chess. She shows us the rivalry and the camaraderie; the ecstatic highs and the excruciating losses; the glamour and the hard work. She describes the coach who told her that her period will affect her standard of play, and gives us thrilling blow by blow accounts of the matches that made history.
Intertwined with Jennifer's own story are those of the top female players from around the world. We meet the famous Polgar sisters, the three Hungarian girls who were all child prodigies; we meet the glamorous jet setters who travel the world partying, and the players who escaped war-torn countries to become champions against the odds.
Chess Queens is a fascinating glimpse into the exhilarating world of chess and an essential book for all the aspiring chess queens of today.
Jennifer Shahade is a brilliant, insightful thinker who never fails to entertain and engage. I'm always amazed by the novel approach she's able to bring to any intellectual challenge and discussion. She's even made me want to learn to play chess - something I swore I'd never do. Jennifer is a true role model to any woman who has ever thought about taking on the worlds that have traditionally been branded male.
Jennifer's book gives readers an insider look into the complex realities of being a female chess player, while also showcasing the badass women knocking down these barriers. Highly recommended!
The fascinating true stories of the lives of champion chessplayers. All women should take up the challenge and pick up a board!
Amazing. I was transfixed throughout, and learned so much. Chess Queens is a meditation on why women have always been so under-represented in the game, and the remarkable lives of those who played on against the odds. An astoundingly intimate, thoughtful and inspirational book by a person who has seen it all from the inside.

An employee recognition program for Barry County employees brought up by Barry County Commissioner Ben Geiger Tuesday brought many questions from other commissioners.
Department heads get recognition, but there are 275 employees who carry out the functions of the county every day who don’t, Geiger said.
He suggested a program to recognize employees using a model the state legislature uses. A traveling trophy goes to the employee picked by other staffers. The first honoree would be appointed by the commission; after that, the winning employee would select the next one to have the trophy, but they would be from a different department.
There would be a little ceremony, every month or two, with a small certificate at a board meeting for the selected employee Geiger said. Commissioner Howard “Hoot” Gibson wanted to know “if other counties do this” and later, “would the employees want it?”
Commissioner Jon Smelker thought it would likely end up a popularity contest. Commissioner Heather Wing wondered if it goes for all departments; Thornapple Manor, the sheriff’s office, the COA?
“Would there be applications from employees and then choose from the applications?” Commissioner Vivian Conner asked “Is this to boost morale or recognizing those achieving more in the workplace?” asked Commissioner Dan Parker.
Geiger said he will bring a formal proposal with more information to the next committee of the whole meeting.
In other business, the committee of the whole recommended the full board approve:

The Apache Software Foundation, the developers of the famous office suite OpenOffice, have said that their software has been downloaded more than 100 million times.
The OpenOffice suite has fallen out of grace since the launch of the lighter and more efficient LibreOffice. It's still integrated in a number of Linux distributions, but it seems that its glory days are over. The guys from The Apache Software Foundation have an entirely different view on the subject.
“Apache OpenOffice reaching 100 million downloads is a remarkable achievement in the project's 29-year history and testament to the power of successful Open Source communities,” said Shane Curcuru, Apache OpenOffice mentor and ASF vice president of Brand Management.
“We extend our gratitude to all the volunteers and users whose contribution, feedback, support, engagement, and enthusiasm keeps us focused on delivering great software. We couldn't celebrate this milestone without them!”
The Apache Software Foundation also provided a few very interesting statistics about the office suite. It seems that Linux is the last platform to use it, and it's overtaken by Windows and Mac OS.

NAVAL AIR STATION SOUDA BAY, Crete, March 6, 2011 — Several Ramstein Air Base units have been key to providing airlift support for the humanitarian crisis on Libya’s borders since U.S. President Barack Obama provisioned military support, March 3, 2011,
The 37th Airlift and Air Mobility Squadrons, working in concert with 17th Air Force (Air Forces Africa) for U.S. Africa Command, are providing this capability. While 37th crews are flying humanitarian relief missions, members of Ramstein’s 435th Contingency Response Group are facilitating the missions, providing everything from communications and command and control to force protection.
As the air component for AFRICOM, 17th Air Force is orchestrating the missions through its planning staff and 617th Air and Space Operations Center, collocated with its Ramstein Headquarters.
After more than two years under AFRICOM, 17th is well-versed in cooperative efforts between Departments of Defense and State. So when a humanitarian crisis followed political upheaval in North Africa, 17th Air Force was ready to assist the State Department-led relief effort, according to Air Force Major General Margaret Woodward, 17th AF commander.
“We were able to quickly answer the call and play our part by orchestrating airlift to ease suffering among the Libyan people and third country nationals who have crossed the borders seeking relief from the conflict there,” Woodward said. “Operating in Africa has given us many chances to work and become familiar with supporting our partners in the State Department. We’re happy to be able to contribute, and we hope, along with the efforts of many other countries, we’ll be able to improve the situation for people in need as a result of this conflict.”
Air Force Lt. Col. Charles “Doc” Schlegel said the 17th effectively brought the units together to execute the humanitarian missions.
“The 17th coordinated the effort and made it possible for aid to be quickly delivered to people who are in need, and for us to move evacuees,” Schlegel said. “We have been working together to adapt to an evolving situation and provide assistance in support of the overall U.S. government response. So far, it’s a great example of Team Ramstein working together.”
Schlegel’s team began flying humanitarian relief mission March 4, 2011, and has delivered relief supplies to Tunisia for USAID and shuttled more than 300 displaced Egyptian citizens to Cairo.
The team’s ability to adapt has been key to their contribution on what Air Force Captain Jason Powell called deemed “an international scale.”
“We started March 3, we partnered our capabilities with the 17th to support the State Department and things are going fairly smoothly,” said the Captain, the director of operations for the 435th’s Contingency Response Element. “Things are always changing, but it’s a testament to our flexibility that we continue to make progress on this mission. We are really stoked, to go in and make a difference for people that are suffering.”

(JustPatriots.com)- US intelligence agencies have determined that Saudi Arabia is manufacturing its own ballistic missiles with assistance from China.
Saudi Arabia had been purchasing completed ballistic missiles from China. But in recent months, several US agencies, including the National Security Council have been briefed on classified intelligence showing multiple large-scale transfers of ballistic missile technology between China and Saudi Arabia.
In recent satellite images obtained by CNN appear to confirm these intelligence reports.
The photos taken in October and November indicate ballistic missiles are being manufactured in at least one location within Saudi Arabia.
At a location near Dawadmi that was constructed with the assistance of the Chinese, satellite imagery shows this facility is operating a burn pit – an area used to dispose of leftover solid propellant from the production of ballistic missiles.
Researchers at the Middlebury Institute of International Studies told CNN that the presence of this burn pit is “the first unambiguous evidence” Saudi Arabia is producing missiles.
This development could have a ripple effect throughout the Middle East at a time when the Biden administration is struggling to restart negotiations with Iran to restrain its nuclear ambitions.
If Saudi Arabia is manufacturing ballistic missiles, it is highly unlikely Iran would agree to stop making its own.
But the problems don’t end in the Middle East. Any US response to Saudi Arabia’s actions would also complicate the Biden administration’s ongoing diplomatic efforts with Beijing on several high-priority policy issues for the White House including trade, the COVID pandemic, and climate change.
According to its report, a spokesperson for China’s Ministry of Foreign Affairs told CNN in a statement that Saudi Arabia and China are “comprehensive strategic partners” who maintain “friendly cooperation in all fields,” including military trade. The Ministry added that this cooperation is not in violation of any international law “and does not involve the proliferation of weapons of mass destruction.”
That’s not a no.
Sources told CNN that the Biden administration is preparing to sanction some organizations involved in the transfer of ballistic technology from China to Saudi Arabia.


The multimeter is one of the most commonly used measuring instruments for electronic enthusiasts. It is an instrument that integrates many common electrical measurement functions. The common multimeter has three basic test items of voltage, current and resistance. Nowadays, many multimeters are developing in the direction of intelligence and multi-function, so many digital products have automatic range selection and extended functions such as measuring capacitance, inductance, frequency, duty cycle, temperature, and triode amplification. Generally, the low-end multimeter technology has become very popular, and some small workshops can produce a variety of multi-function digital multimeters, and the price is very low. The price of a multimeter in the market ranges from a few yuan to several thousand dollars. How do we choose a multimeter that meets the needs of our application?
The purchase of a multimeter should be considered from the aspects of product performance, brand, appearance, after-sales service, price and so on.
Performance of the multimeter The performance of the multimeter mainly includes five aspects: measurement accuracy, extended function, reliability, durability, and product safety characteristics.
The accuracy of the multimeter includes two aspects: one is the accuracy of the measurement, which is commonly referred to as the “error”; the other is the resolution of the measurement, which is commonly referred to as the “number of bits of the multimeter”. The measurement resolution of the multimeter is not necessarily related to the measurement accuracy. Although it is generally said that the measurement resolution is higher and the measurement accuracy is better, it is not absolutely true.
Some manufacturers are opportunistic, the product seems to display more digits, more functions, but limited by cost and technology, can not control the accuracy and stability, a three-and-a-half-digit multimeter measurement accuracy is better than one It seems entirely possible that the station looks like a product with four and a half displays. The resolution of the multimeter is based on accuracy, otherwise the display of high digits is not measured. In the high-demand measurement, the measurement accuracy of the multimeter is quite demanding, and the measurement accuracy of the multimeter is one of the main indicators for measuring the product grade.
The measurement accuracy of a multimeter will slowly degrade over time, which is the main reason why the instrument needs regular calibration. The high-reliability multimeter has a long service life and is resistant to harsh external environments. The cause of the multimeter error is inherent and external: the external cause is the use environment and the frequency of use. High and low temperature and high humidity will affect the characteristics of the components. As the number of times and time increases, wear and aging It is inevitable; the internal factors are the quality of the product, from circuit design to component selection and manufacturing processes. The same function of components, there are expensive but low temperature coefficient, excellent performance, durable products, but also low-cost but flat performance products, the use of components of the grade is directly related to the cost of the product, manufacturers of different brands are Different considerations.
Taking the high-end brand, the high-stability components and design are selected according to the principle of high quality and high price, ensuring the reliability and durability of the product. Although the price is higher, the product performance is stable, the service life is long, and the repair rate is low. The brand that takes the “price” route strictly controls the cost and even shrinks. Although such a product is cheap, it may not be easy to find the problem at the beginning of use, but as the use time is extended, the problem will be slowly exposed. Fortunately, most low-end users are not sensitive to the accuracy of the multimeter, and there is no means of measurement. Generally, the dry battery display shows 1.5xxV, and the measured power supply shows 22xV. So many users say that their cheap multimeter quality. Ok, it hasn’t been broken for many years. In fact, many products are really taken to measure, and they are no longer in the “state”.
The durability of the multimeter is closely related to the design and quality of the product. Durable products are designed with the multimeter in a tough environment, including wind and rain and accidental drops and collisions. High-strength housing materials and impact-resistant design and high sealing are the basis for increased product durability. Internal high-quality components can delay long-term wear and tear. Some high-quality multimeter dials are made of high-quality metal, and the contacts are made of thick gold plating, which can resist oxidation and wear. Some famous brand multimeters produced more than 10 years ago have been repeatedly changed in the second-hand market, and even picked out from foreign garbage, they can still be used normally, which shows their durability.
Many users talk about the performance of the multimeter, often focusing on the accuracy of the product. In fact, the security of the product is more important, and it is closely related to the user’s personal safety. It is difficult to avoid accidental operation. In the case of overload or incorrect setting, the multimeter can guarantee to avoid personal injury to the user and keep the safety of the instrument itself, which is related to the safety design of the product. More than one design margin will cost more, but it will be more secure. Strict implementation of safety standards is responsible for life.
High-end multimeters often use expensive fuses. For example, the price of a fuse in the high-end series of Fluke is more than 60 yuan. The price of a fuse can completely buy one or two cheap multimeters. High-performance, high-response fuses are more sensitive and fast to isolate overload accidents, minimize the possibility of explosions, melts, etc. due to severe overload, and the internal resistance of the fuse tube itself is extremely low. The effect of stringing into the circuit is minimal.
The extended function is the performance of the modern digital multimeter. In addition to the traditional basic measurement of voltage, current and resistance, common extended measurement functions include on-off measurement, diode measurement, triode measurement, capacitance measurement, temperature measurement, frequency measurement, duty cycle measurement, maximum value retention, and simulation. Pointer quick response display, built-in anti-interference low-pass filter, PC communication interface, and misoperation protection. The extended measurement function can sometimes replace some special instruments, expand the application range of the multimeter, achieve a multi-purpose table, and improve work efficiency and automation rate.
The brand is the guarantee of the quality of the multimeter, and it is also the embodiment of the product grade. A well-known brand is the accumulation of the market after many years, and is also the commitment of manufacturers to users. Although the low-end multimeters of some international famous brands are not brilliant in the measurement accuracy and expansion functions that the mass users pay attention to, they are relatively solid in terms of product reliability, stability, safety characteristics and other intrinsic qualities that are not often valued by users. Meticulous. Users can use it for a long time to realize the meaning of high quality products. Many users like to compare the performance of products by comparing parameters. The authenticity of the product parameters provided by famous big brands is more secure.
As the saying goes, “interlacing is like a mountain.” In the era of industrial development, the division of the industry has become more and more refined, and the technologies involved have become more and more professional and narrow. In the same electronics industry, the masters of electrical maintenance are generally not proficient in instrumentation expertise, and most of them stay at the stage of instrument application, so most multimeter users do not have in-depth understanding of the product like the industry insiders of the multimeter manufacturing industry. It is also unrealistic to become a multimeter expert to buy a multimeter. Ordinary basic knowledge plus brand guarantee is a shortcut to purchase, because the factory has designed a series of different grades for different grades of application from a professional perspective. Trust in the brand is widely accepted in the electronics industry. When you come up with a high-end brand-name multimeter, people who know it will naturally add a little trust to your test results and also recognize your professionalism.
The design is related to the durability, indestructibility, and operational certification of the multimeter. As the multimeter’s service life increases, the error becomes larger. At this time, professional calibration is needed to re-improve the measurement accuracy of the multimeter and reduce the error. For the current mainstream digital multimeter, this kind of calibration often only needs to cooperate with special instruments to perform software calibration on the data in the machine. The calibrated multimeter can fully meet the performance of the new product, and the cost of calibration is far lower than the purchase. The cost of the new form. The professional calibration can greatly increase the life of the multimeter, thus reducing the cost of the instrument. In addition to maintenance and calibration, high-end after-sales services include advanced services such as technical support.
Pointer multimeter purchase
The high-quality pointer multimeter should have a high-quality mechanical head, flexible and durable gear dials, stable system accuracy, high voltage resistance, internal resistance, complete protection mechanism, and rugged housing. The high-quality pointer head has a good response speed and has appropriate damping characteristics. Some high-grade dials are also equipped with mirror strips to reduce readout errors. Generally, a large-area dial is easier to read, but for a small portable multimeter, the overall volume of the product should also be considered. The current-grade application-grade products of domestic pointer multimeters have a DC accuracy of 2.5, and a small number of scientific-grade products have reached 1.5 and 1.0. The higher-level pointers are mostly dedicated to single-function single-range, and the actual application is 2.5. The table is enough.
In the era of digital multimeters, high-precision measurement is already the world of digital meters, and the practical significance of high-end pointers is declining. Some users think that the multimeters produced in the early stage use a large number of high-precision wirewound resistors, and the inside of the back cover is full, and the multimeters produced in recent years use the color ring resistors commonly available on the market to disassemble the interior of the back cover, so the quality Declining, new products are not good, but it is not entirely true. Early multimeters used wirewound resistors because the accuracy of the carbon film resistor was not good enough at the time, and it was easier to obtain a resistor with a small resistance error by the conventional wire winding method. Over time, the accuracy of the current color ring resistance (carbon film resistance and metal oxide film resistance) is greatly improved. With the secondary screening, it is easy to obtain the resistance that meets the error requirement, and the price of the color ring resistance is cheaper than the wire wound resistance. Many, so the use of color ring resistance is an inevitable trend. Appearance The seemingly similar color ring resistance is also graded, including the accuracy level and stability level. As long as the product is properly adjusted, it can produce a multimeter that meets the technical specifications.
The high-end products featured in the domestic pointer multimeter are: MF35 and MF18 with DC accuracy of 1.0, MF12 and MF14 with DC accuracy of 1.5, with 10 microamp test block and DC internal resistance up to 100kΩ/V. High sensitivity MF10 type. These multimeters represent the highest level of this country’s pointer table, and have a certain collection value, especially some old factory watches.
However, the use value of these high-end performances is not high. This is because these pointers, which were considered to be highly accurate in the past, cannot be compared with the current high-end digital meters. Users who demand high measurement accuracy should now use high-end desktop high-precision digital meters.
Digital multimeter purchase
Digital multimeters are the mainstream in the current market. Buying on demand and focusing on the quality of products is the wise choice. The average user does not have to pay too much attention to the resolution of the product (display digits). For even applications such as appliance repair, the most common three-and-a-half digit digital meter is enough. High-resolution testing is the most common case. There is no substantive help. For most users, the multimeter is practical and sufficient, and it is not necessary to buy high-priced, high-end products. Brand name is the guarantee of quality, and the mid-range products in the general product line have the highest price/performance ratio. Although the high-end products have excellent performance, in addition to the high initial purchase cost, the later use costs will be higher.
First, high-performance products consume more power and battery overhead. Secondly, the cost of consumables (such as fuses) is relatively high. For example, a fuse of FLUKE high-end multimeter has more than 60 yuan, and the loss caused by one misoperation will increase significantly. Again, the post-maintenance costs are also related to the grade of the multimeter, and the maintenance cost of the high-end multimeter is very high.
For some users who deal with high voltage and high current, the safety of the multimeter is more important than the measurement accuracy. The general high-precision multimeter is suitable for scientific and research-grade applications. Especially the desktop multimeter is more suitable for laboratory use. The true multimeter with more than seven and a half ultra-high precision requires strict specifications, including proper temperature and humidity. It needs to be regularly calibrated. If it is placed as casually as a normal multimeter, it will be used at startup and it will lose its practical use.
From the measurement technology, there are two methods for measuring the rms value of the digital multimeter: the average rectification principle and the true rms principle. The former method has a lower cost ratio and is mainly adapted to the measurement of a sine wave. When a square wave is encountered, the reading will be too large. Although the latter method is relatively complicated to implement, the measurement of various waveforms is relatively accurate. Most middle and high-end multimeters use true RMS measurement methods. A multimeter with true rms measurement will have the word “Ture-RMS” on the meter, which has become a sign of the digital multimeter.
In addition to measurement accuracy and measurement resolution, the multimeter’s measurement performance also has a very important indicator response speed, which is the time to start measuring stable readings. This also reflects the processing power of the multimeter processor, and the high-end digital meters. Has a very fast response speed. It should be noted that this is not directly related to the speed at which the multimeter screen is refreshed. Some users complain that their digital multimeters are measuring slowly, which is related to this indicator. There are many mid-range and low-end multimeters that avoid this problem in the parameter list.
For ordinary home users, there is basically no requirement for measurement accuracy. Consider cheap and good products, such as UT33 B, which is about 30 yuan for Unid. As long as the products of regular manufacturers can be used without too much, put them in the toolbox. Needs from time to time

The Department of Mineral Resources will hold talks with mining companies and the Department of Trade and Industry about the requirements for broad-based black economic empowerment levels, something Kumba Iron Ore CEO Chris Griffith flags as a problem.
Addressing doubts expressed at the two-day Mining Lekgotla about mining companies’ claims of black ownership and empowerment, Mr Griffith said there had to be one standard set of numbers which both sides agreed was fair.
"The issue of mining companies and the department (Department of Mineral Resources) disagreeing on the transformation statistics has been coming for some time now. It creates distrust in the mining industry and it’s something we need to tackle," Mr Griffith said on Wednesday.
› Mines to discuss 'black ownership'
› NUM blasts Numsa over nationalisation
Mining groups report their empowerment data to the Department of Mineral Resources which verifies the information.
"Progress really does need to be made in making sure we can come up with one standard set of numbers that the industry and the department agree on. These will then be the reflection and rate of transformation of the mining industry," Mr Griffith said.
The Chamber of Mines said in Parliament last year that not one of its members was below 15% ownership levels and some were at 50%, giving a weighted average of 28%, well above the 26% level required in 2014.
The department said the figure is lower than that and that by 2009 just 9% had been reached against a target of 15%.
Mineral Resources Minister Susan Shabangu said her department would talk to mining companies to reach "a common understanding" and was talking to the Department of Trade and Industry about the broad-based black economic empowerment codes it had introduced compared to the empowerment requirements in the Mining Charter.

Chemical aspects of heather burning.
In laboratory experiments mineral nutrients, particularly K, were readily dissolved from the ash left when heather was burnt but the rate of solution was lower after combustion at a higher temperature. The potential losses through downward drainage of rain water are lessened by retention in the soil of ions from the percolating solution; the effect was most marked in organic and clay soils and least marked in sandy soils. Losses of dissolved nutrients were possible where surface drainage occurred over impervious soils but such losses were reduced on wet moorlands by absorption into Sphagnum. Over half the C, N and S in burnt heather was driven off with the smoke. Where burning causes losses from the plant-soil complex, precipitation appeared to restore the mineral nutrient balance in a short time unless the soil was very porous. Replacement of N by rainfall is slower but microbial action may be important here.

Unchecked looting guts Egypt’s heritage, with one ancient site ‘70 percent gone’
By Betsy Hiel | TRIBLIVE
A wispy-haired mummy’s head, bleached skulls, and arm and leg bones are piled outside looted tombs.
A mummified hand with leathery-skinned fingers pokes from the sand.
Ancient burial wrappings from mummified bodies — torn apart to find priceless jewelry — unravel across the desert like brown ribbon, or tangle near broken bits of wooden coffins still brightly painted after nearly 3,000 years underground.
With bones scattered everywhere, this 500-acre plot looks like the aftermath of a massacre rather than an ancient burial ground.
“You see dogs playing with human bones, children scavenging for pottery,” says Egyptian archaeologist Monica Hanna, stepping cautiously around grisly remains and deep pits dug into tombs by looters.
Salima Ikram, an expert in tombs and mummification who heads the Egyptology unit at American University in Cairo, gasps in horror in her home while examining Tribune-Review photographs of the site.
“These scattered remains … brutally pulled apart in search of one shiny piece of metal,” Ikram says in disgust.
“This is most horrific — someone’s ribs!” she suddenly exclaims. “Oh, God! It’s like the killing fields!”
Thieves, explorers and archaeologists have raided Egypt’s ancient sites for centuries. The Tribune-Review first reported in February that the looting had become a free-for-all after a 2011 revolution toppled one government and introduced continuing turmoil.
The tomb raiding threatens some of Egypt’s — and the world’s — most revered and valuable heritage sites, many of which have never been properly studied or catalogued, experts say. A few experts privately accuse the Muslim Brotherhood-led government of President Mohamed Morsy of ignoring the threat.
Some Islamist religious leaders have contributed to the frenzy by ordering “pagan” antiquities to be destroyed, or issuing directives on the “correct” Islamic way to loot them.
Police and local authorities insist they are overwhelmed by lawlessness and outgunned by criminal gangs with heavy weapons smuggled from Libya.
Meanwhile, the threatened heritage is a low priority for many Egyptians beset by daily electrical outages, fuel shortages, higher food prices, rising street crime and political instability.
For others, that heritage is a chance to cash in. Looted objects are sold in dirt-poor villages near sites such as Abu Sir al Malaq; others go to wealthy collectors, particularly in the United States, Europe, Japan and the Middle East, experts say.
Last week, Egypt’s new antiquities minister pledged to improve security “at all archaeological sites and museums.”
But that appears to be too little too late for the sprawling cemetery complex, or necropolis, in the governorate of Bani Suef. Of three sites examined by the Trib – the others are Dahshour and El-Hibeh – it is the most extensively ravaged.
Looters rip apart ancient mummies — here an arm is discarded — looking for potential amulets or gold jewelry in Abu Sir Al Malaq, according to Dr. Salima Ikram, head of the Egyptology unit at American University of Cairo.
Pieces of history
Abu Sir al Malaq is about 70 miles from Cairo, in the midst of green farm fields, palm and banana groves, all fed by a tributary of the Nile.
Once named in honor of the Pharaonic god Osiris, it is thought to have been a burial ground from 3250 BC until AD 700.
Archaeologists excavated it in the early 20th century, and its artifacts are found in museums around the world, according to Nadia Ashour, who oversees antiquities in Bani Suef. She calls it “one of the most important antiquity areas” in the governate.
It also is one of the most looted.
Hanna, the Egyptian archaeologist, has surveyed the site repeatedly.
“The looting is pandemic, every night and even in the morning,” she says.
Nearby villagers, asked for directions to the site, respond: “Antiquities? Do you want to buy antiquities?”
Ikram, the university Egyptologist, says Trib photos from the site indicate “intact tombs (were) completely robbed, bodies ripped apart. It is a disgrace.”
Some photos show ancient dog bones in front of looted tombs — the remains of animals buried in honor of Anubis, a Pharaonic, jackal-headed god worshipped as a protector of the dead.
“Here’s a piece of a coffin and the person it belongs to,” Ikram says, studying the photos. “For almost 3,000 years, they have been left undisturbed. They were not meant to be left like this, to be eaten by dogs and foxes and jackals … broken apart by greedy people.”
Hanna, picking her way across the site, points out chunks of painted or inscribed limestone tomb walls. Looters often “break off the pieces that have the engraving on it, to sell,” she says.
Some of the discarded linen mummy wrappings are mixed with papyrus, gypsum and mortar, then elaborately painted — “a trait of wealthier mummies,” she explains.
Sighing, she adds: “I think 70 percent of the site is gone.”
‘Cried the whole way home’
Bani Suef’s antiquities director, Ashour, says she is “heartbroken” that “sneak digging” is destroying such sites throughout Egypt.
Although Islam and Christianity forbid grave-robbing, she says, some Egyptians think their ancestors were pagans and, thus, are fair game to be robbed.

Understanding the Vaping Dangers – Do you know the Main Vaping Dangers?
The vapors produced by electronic cigarettes contain a amount of known and unknown vaping dangers. As more info about these products comes to light, the general public is now more educated and is beginning to question the safety of e-juices. It is also becoming increasingly clear what the true dangers are from regular e-juice consumption. In this post we will check out two of the newest issues that have surfaced because of increased knowledge. We will look at possible lung disease associated with e-juices and why quitting is indeed important.
First, let’s take a closer look at what we realize about the long-term effects of e-juice. The American Cancer Society has warned for quite a while about the potential cancer-causing toxins within cigarette smoking. There is even a widely-accepted rule of thumb, “A glass of red wine each day keeps the wrinkles away”. So, it stands to reason that should you consume a lot of, it might have a similar influence on your body as using tobacco.
A couple of things that have been strongly suspected are formation of small pieces of crystals in the e-juice, and a potential growth of carcinogens, toxins, and chemicals in the vapor. Most of the fear is apparently centered around the possibility of Nicotine/Vapour containing cancer-causing agents, however some other studies have claimed that there may be some truth to the matter. Among the latest studies directly contradicts the previous claims, however, saying that there will not look like any evidence that e-cigarette use can cause cancer or tumors.
Lung disease is one of the major concerns, especially because of the increasing age of the population. Recent research shows that younger people are starting to suffer from shortened lifespan because of exposure to carbon monoxide smoke. When there is a causal relationship between smoking and lung disease, it would only seem fair that we take every possible step to eliminate this threat. The concern about long-term effects is not as important as finding the safest way to administer e-juices to our family members.
As stated earlier, there has been lots of interest in e cigarettes since they seem to offer an alternative to the traditional method of quitting. However, if you consider the fact that using tobacco has been proven to result in a variety of cancers, heart disease, and many other ailments, it really is difficult to understand why anyone would elect to go the e-pipe route. It is also important to realize that if you stop using them and then resume cigarette smoking, a lot of the symptoms that were associated with cigarette smoking will return.
Because of this , it is important to be certain that the electronic devices that you decide to use as a smoking alternative are FDA approved for use as a Smok Novo genuine electronic device. Only people that have proper licenses and those which have undergone extensive testing ought to be allowed to sell e-cigarette pens to the public. Also, the average person selling these e-pens to you should have the duty of wearing a medical ID tag which will allow you to be checked for just about any lung injury or cancer risk at any time. Lung injury and cancer can simply play havoc on your quality of life, and you want to make sure that you protect yourself from these horrible long-term effects.
There are several very real concerns linked to the intake of e cigarettes and the potential long-term effects. As the vapor is produced without combustion involved, you will find a much greater chance that some type of toxic chemical could be released in to the user’s lungs in the event that you were to ever create a lung injury from the vapor product. The very same concern is associated with popcorn lung. These harmful ingredients have the ability to burn your lungs and when you were to ever create a chronic lung injury from the vapor product, it could be extremely difficult to clear up.
To handle the problem of no combustion involved with these devices, the latest technology in e cigarettes would be to utilize the use of VITAMIN E ANTIOXIDANT acetate, generally known as Alpha Arbutin. This ingredient has the capacity to absorb in to the lungs and raise the oxygen permeability of the lungs. With an increase of oxygen permeability, the power of the lung to soak up nutrients that are needed to maintain healthy cell function is enhanced. Also, because VITAMIN E ANTIOXIDANT acetate is naturally produced in the body, it would not cause any toxicity or long-term health problems. With this technology, you’d be protecting your wellbeing and preventing a potential heart attack, stroke, as well as cancer.

About 20 years ago, the body’s own cannabinoid receptor system (endocannabinoid system) was discovered. This discovery was the starting point for an intensive exploration of the hemp plant for medical purposes.
The cannabis plant cannabis sativa contains a considerable number of so-called phytocannabinoids (approx. 85) from the group of terpene phenols, which so far have not been discovered in any other plant (source: wikipedia with further references). In addition, hemp also contains a variety of non-cannabinoids, over 120 different terpenes and 21 flavonoids (loc.cit.).
The most investigated cannabinoid (loc.cit.) is certainly Delta-9-tetrahydrocannabinol (Delta-9-THC) or just THC. When the term medicinal hemp is used in general language, this discourse basically and essentially refers to the active substance THC.
At this point we refrain from discussing further cannabinoids or other substances for reasons of pharmaceutical legislation (keyword: „Präsentationsarzneimittel“ (presentation pharmaceuticals)].

Few can claim to have forged an entirely original genre of music, but in 1966, Corky Siegel did just that. Guiding the blues of Howlin’ Wolf and Muddy Waters out of the smoky cavern of Big John’s and onto the stages of the Chicago Symphony, New York Philharmonic and beyond, the harmonica-playing mad scientist had the tuxedo-and-gown crowd on its feet, clamoring for more of this blues-classical alchemy. These days, the harmonica virtuoso and composer is continent-hopping with Indian percussion and string quartet in Corky Siegel’s Chamber Blues, continuing to bring classical and blues fans shoulder-to-shoulder…and obliterating musical categorization in the process. – Doyle Armbrust

A new stainless steel and concrete bridge, the first of its kind in the UK, has opened to pedestrians and vehicles in Pooley Bridge, Cumbria.
It replaces its 250-year-old stone predecessor, which was destroyed during severe flooding as a result of Storm Desmond in 2015. The new single-span bridge has been designed to withstand extreme weather conditions and is in keeping with its location in Ullswater on the edge of the Lake District National Park.
Hanson UK worked with contractor Eric Wright Civil Engineering Ltd to create a bespoke concrete mix for the lower arch of the steel bridge, designed and constructed to provide structural strength, and also supplied and laid the asphalt to complete the project.
The steelwork for the new bridge was manufactured off-site in two sections, fabricated and welded on an adjacent piece of land, where the concrete lower arch was installed to allow the whole structure to be lifted into place over the River Eamont.
The high early strength concrete mix included Hanson Regen GGBS (ground granulated blastfurnace slag), a cement replacement product which enhances the durability of the concrete while adding to its sustainability credentials. It is a by-product and using it to replace one tonne of Portland cement reduces the embodied CO2 of the concrete by around 780kg. Its use in large pours also helps minimise the production of heat, reducing the risk of thermal cracking.
In total 1,200 cubic metres of concrete containing Regen have been supplied by Hanson’s nearby Penrith concrete plant to create the lower arch, bridge deck, bridge abutment and walls, highway approach retaining walls and several temporary works.
“Concrete supply to this project was always going to be a challenge due to the location, unique characteristics of the bridge and the tight deadline,” said Nick Graham, technical sales officer at Hanson Concrete.
Technical services manager Terry Balmer added: “Our technical team was involved early in the design stage due to the complex concrete requirements, especially for the high-quality visual concrete that makes up the deck composite, and this partnership working was fundamental to the success of the project.”
To complete the project, Hanson supplied 275 tonnes of asphalt from its nearby plant at Shap, which was laid by the company’s specialist contracting team. This included 130 tonnes of Tufflex, chosen for its durability and high resistance to cracking, for the surface course.
In addition to the complex nature of the bridge, the final abutment work, concrete arch and composite deck – as well as the asphalt – were all supplied under the added pressure of the Covid-19 pandemic and the associated issues entailed with furloughed staff and social distancing protocols.

SanFrancisco Symphony Kids
The San Francisco Symphony has created a fabulous resource for children. Their website includes musical games, information about famous composers, and a classical music listening library. I encourage you and your child to explore the website together! In music class, we lie down on the floor and close our eyes while we listen quietly to music. Maybe you and your family can try the same at home! Recently the students listened to Largo from Symphony No. 9, from a New World by Antonin Dvorak.
The Kindergarteners created pieces of music using Sid the Science Kid’s Sandbox Symphony. The students made music with animal sounds, nature sounds, and found objects. You can find the Sandbox Symphony here:
PBS Kids also has other music games. Check them out with your child and make music together!
