first_imgWinner: Nora StapletonNiamh Briggs accumulated 18 points as Ireland outfought and outfoxed a physical USA team to begin the Women’s Rugby World Cup in winning style with Donegal’s Nora Stapleton putting in a great performance for the Irish in Paris.Tries from prop Ailis Egan and star full-back Niamh Briggs sandwiched a Lynelle Kugler effort as the girls in green led 20-10 at half-time in muggy Marcoussis.A Carmen Farmer try brought the Americans back to within three points, but Briggs’ 60th-minute penalty proved to be the last score of an end-to-end Pool B opener with another Donegal player Larissa Muldoon on the replacements bench Although the US had won the sides’ last meeting 40-3 at the 2010 World Cup, Philip Doyle’s Ireland side have certainly kicked on since then – as evidenced by last year’s Grand Slam success.Briggs slotted a third minute penalty to give them an early lead here, Ireland getting off to a strong start on the back of a Claire Molloy-won lineout.But Doyle’s charges allowed the USA a foothold when they lost ruck possession near their 22 and Grace Davitt infringed at a subsequent ruck. The Americans turned down a kickable penalty and although their powerful lineout maul was stopped, flanker Kugler found space close in to score the opening try.Kimberly Rozier converted for a 7-3 scoreline but the scores continued to come at a rapid rate, Briggs splitting the posts in the 11th minute with a penalty from a similar distance to her first. The influence of the American set piece increased towards the end of the first quarter, but Siobhan Fleming got in to disrupt a lineout in her 22 and a follow-up choke tackle relieved the pressure.Clean possession was at a premium with the tackle and breakdown area fiercely competitive, while a promising break by Ashleigh Baxter was well defended.On the plus side, Ireland’s maul was beginning to look a potent weapon. The pack built momentum with three well-constructed drives, however half-backs Tania Rosser and Nora Stapleton were unable to unlock the US defence.The Irish forwards kept pressing and a 29th minute maul – outside the American 22 – led to lock Sarah Walsh being sin-binned. Opportunity knocked from the penalty and they needed no second invitation as Sophie Spence was hauled down short before Egan, with support from her front row colleague Gillian Bourke, plunged over from the ruck.Briggs’ successful conversion gave Ireland a 13-7 lead. The six-point buffer was a brief one though as hands in the ruck from openside Molloy earned her ten minutes in the bin and Rozier took the three points on offer. However, Ireland struck for their second try just before the interval as turnover ball from a lineout led to strong carries from Egan and Spence, who consistently punched holes in the defence, and a final pick-up at a ruck from Briggs saw her wrestle past two American defenders for the score.The Waterford woman converted her own try to put 10 points between the teams at the break, but again the US were quick to respond early in the second half.Barely a minute had elapsed when American lock Farmer muscled over from a couple of metres out. Number 8 Heather O’Brien had fumbled the restart, allowing the US to build immediate pressure from a scrum. Rozier added the extras for 20-17.Ireland’s error count increased as they coughed up ruck ball and the usually reliably Briggs let a high ball slip through her grasp, however Alison Miller did well to bring down the dangerous Vanesha McGee. There was little between the teams in a tight third quarter. Crucially though, centre Jenny Murphy made a terrific impact off the bench with two forceful runs – the second seeing her link well with Rosser off another muscular maul from the pack.The same attack led to USA replacement Shaina Turley picking up a yellow card close to her try-line and Briggs mopped up with a well-struck penalty right on the hour mark.Ireland were now back in the ascendancy as Baxter and the tireless Lynne Cantwell caught full-back Meya Bizer in possession. They had a tight grip of territory as they forced hurried clearances from the Americans with 15 minutes left.Briggs slid a drop goal attempt wide as Ireland tried to move clear by more than a converted try, entering the closing stages.Their greater experience showed as they continued to control territory and a hard-won victory was theirs, albeit with Briggs missing a last-gasp penalty which would have denied the US their losing bonus point.Next up for captain Fiona Coghlan and her team-mates is a fascinating first ever clash with New Zealand on Tuesday. The Black Ferns, who are the defending champions, overwhelmed Kazakhstan 79-5 earlier today.Said Coghlan: “There are aspects we need to improve on and we’ll look at that going into the New Zealand game.“But I think when you’re down, the ability to come back, go down and again and come back, that shows what this team is made of and the character that’s in the team.“Particularly in the last 10-15 minutes, we were all on the same page and everyone knew what we had to do in order to get the win. We’ll take great heart from this win.”USA: Meya Bizer; Vanesha McGee, Akalaini Baravilala, Emilie Bydwell, Sadie Anderson; Kimber Rozier, Jocelyn Tseng; Hope Rogers, Katy Augustyn, Jamie Burke, Carmen Farmer, Sarah Walsh, Jillion Potter, Lynelle Kugler, Kate Daley.Replacements: Kittery Wagner, Sarah Chobot, Sarah Wilson, Sharon Blaney, Shaina Turley, Deven Owsiany, Hannah Stolba.Ireland: Niamh Briggs; Ashleigh Baxter, Lynne Cantwell, Grace Davitt, Alison Miller; Nora Stapleton, Tania Rosser; Fiona Coghlan, Gillian Bourke, Ailis Egan, Sophie Spence, Marie Louise Reilly, Siobhan Fleming, Claire Molloy, Heather O’Brien.Replacements: Sharon Lynch, Fiona Hayes, Laura Guest, Paula Fitzpatrick, Larissa Muldoon, Jenny Murphy, Jackie Shiels.STAPLETON TASTES SUCCESS AS IRELAND SEE OFF USA IN WOMEN’S RUGBY WORLD CUP was last modified: August 2nd, 2014 by John2Share this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window)Tags:IrelandLarissa MuldoonNora StapletonUSAWomen’s rugby world cup 2015last_img read more

Performance drug used by Lance Armstrong not effective: study

first_imgLondon, Jul 3 (PTI) EPO, a doping drug that was used by American cyclist Lance Amrstrong – for which he was stripped of his seven Tour de France titles – may have little effect on performance of athletes, a study has found.One of the most celebrated athletes, the road racing cyclist Armstrong was the 1993 professional world champion, and had won the Tour de France a record seven consecutive times from 1999 to 2005.However, in 2012, he was banned from sanctioned Olympic sports for life and stripped off his seven Tour de France titles after he confessed to using the drug erythropoietin (EPO).Researchers from Centre for Human Drug Research in the Netherlands conducted a trial on about 48 well-trained non- professional male cyclists aged between 18 and 50 years.They found that while performance was improved in high intensity tests, endurance and road race performances were similar for those who took the drug rHuEPO and those who did not.They found that the drug led to elevated levels of haemoglobin and adhesion molecules which could potentially increase the risk of thrombosis.In the trial, half of the participants were given weekly injections of rHuEPO, and half were given a placebo (saline solution) over 8 weeks.The aim was to increase the levels of haemoglobin in the participants of the rHuEPO group by 10-15 per cent compared to the start of the study. The doses used were consistent with known practises in professional cycling.The trial involved a series of tests to evaluate different types of performance parameters.advertisementThe first test involved a ramp test, where pedalling resistance was increased every 5 minutes until exhaustion (taking between 30-50 minutes).The second test involved a 45 minute endurance test at the highest power output. The final test, 12 days after the final injections, involved a 110 kilometre (km) cycle followed by a 21.5 km road-race up Mont Ventoux, which often features in the Tour de France race.Mean haemoglobin concentrations, and performance parameters in the high-intensity laboratory test were higher in the rHuEPO group compared to placebo. Gross efficiency, heart rate and other respiratory parameters did not differ between groups.In the endurance tests, mean power output, oxygen consumption and Mont Ventoux race times did not differ between groups.The same was true for cycling economy, mean heart rate, and lactate levels, researchers said.There was no difference in adverse events between the two groups, however the endothelial function markers E-selectin and P-selectin were significantly increased in the rHuEPO group, potentially increasing the risk of thrombosis.”We found that while rHuEPO increased performance in a laboratory setting on high intensity tests, the differences largely disappeared in endurance tests, and were undetectable in a real-world cycling race,” said Jules Heuberger from the Centre for Human Drug Research.The study was published in the journal The Lancet Haematology.

Overcoming a major challenge with standard modular solutions

first_imgThis article describes the complete renewal of the Moscow Metro passenger information and security system with standard modular embedded computer solutions. By Alessandro Santini, SECO                                           Download PDF version of this articleThere were major challenges to overcome: the customer needed to renew the on-board sensors as well as the video surveillance and digital signage devices of the Moscow Metro System at short notice. As a matter of paramount importance, the new devices needed to guarantee over 10 years of operation and more than 30 years of maintainability. The solution to be adopted needed to combine low power consumption and high-performance graphics in a small, modular scale platform. All of this while complying with railway regulations which require modules to be reliable even in the harshest environments, i.e. with a temperature range of -40/+85°C.The question was: how best to renovate the Moscow underground in a timely manner while ensuring full compliance with current regulations in terms of safety and long-term reliability of the deployed solutions? This has been the challenge undertaken by SECO since Q3 2016. Global restructuring with regard to IT technology involving not only the onboard sensors but also the video surveillance system, the emergency communication service, the digital signage devices and the data traffic between the wagons and the front section in the Moscow Metro.Figure 1. The solution needed to achieve superior capabilities graphically and at the same time low power consumption. A leading company in the development, production and integration of electronic systems specializing in Metro systems and railways was instructed to restore the electronic and digital equipment for the Moscow underground. The customer, located in the Russian Federation, was highly experienced with regard to the railway digital communication system but needed a trustworthy third party with solid expertise in embedded hardware to design, prototype, mass produce and implement a suitable scale solution. The project was extremely complex and entailed a multitude of challenges to overcome.First and foremost, meeting industrial quality standards while ensuring a rapid time to market. Quality refers to two aspects in this context: performance and power consumption on the one hand, security and longevity on the other. With regard to the former, the envisaged solution needed to achieve an optimal performance/power consumption ratio – in other words, superior capabilities graphically and at the same time low power consumption. Of crucial importance, furthermore, are the durability, maintainability and reliability of the entire system. As an essential condition, the new devices needed to guarantee 10+ years of operation and 30+ years of maintainability. Last but not least, the system needed to work within a broad range of environments as required by the EU regulatory requirements, that is to say, everything needed to be perfectly functioning within a temperature range of -40/+85° C.In terms of time to market, with this point being extremely important, it was a critical factor to take into account the fact that the Moscow Metro is a major artery of the city network, serving millions of people every day. Consequently, at no stage could the renewal interfere with the daily activity of its users. Of course, cost effectiveness also played a decisive role as the smallest of increases would result in a significant scale difference. Bottom line: from the initial design to the final implementation the renovation needed to be very rapid yet precise in every detail.To fulfill these requirements SECO worked closely with the customer from the beginning, analyzing the context, assessing all the issues and gathering feedback from the development phase to the fine-tuning. Close collaboration with clients is fundamental in order to succeed. Understanding the framework in which SECO has to operate is essential and it is only by paying the utmost attention to the demands and feedback of the customer that it is possible to achieve the goal. SECO does not come to the table with a pre-planned solution in mind. On the contrary, it places great importance on listening to the customer as well as analyzing the problem and exchanging our know-how with the commissioner. The customer is indeed the most valuable resource.At the end of the analysis phase SECO had devised an ARM/x86 standard modular solution, the only one ticking all the boxes. Regarding the performance/consumption ratio, such a platform ensures good graphics performance and high energy efficiency, while also being optimal in terms of cost effectiveness. Additionally, a standard module represents the best fit in relation to scalability. Once the platform was defined, SECO, together with the customer, chose the set of modules to be deployed, namely the ARM and x86 Qseven and µQseven standard modules.Figure 2. Both the ARM and X86 Qseven modules complying with railway regulations could be delivered immediately in volume. Regarding the x86 modules, SECO opted for the Q7-A36, a Qseven based on the Intel Atom E3800 and Celeron families (SoC) (former code name Bay Trail) as being a cost-effective and mobile-oriented module with eMMC and camera interface as well as featuring industrial-grade components (temperature range -40/+85°C). The ARM solution was instead the µQ7-962, a µQseven module based on the ARM Cortex-A9 i.MX6 SoC, unique given its optimal balance of performance and size. Interestingly, the µQ7-962 is a flexible solution, perfect for high-end, multi-display scenarios, also available in the industrial temperature range, and is available in two versions: the high-performance one, with Quad Core CPU, and the more cost-effective Solo Core solution. Finally, in order to be regulation-compliant, modules were produced with PCB ISOLA PCL370HR and compliant Novec 3M EGC-1700 coating.SECO was uniquely positioned to address all these mentioned issues. Firstly it was able to quickly supply both the ARM and X86Qseven modules complying with railway regulations, which means a significantly rapid time to market and ultimately an improved ROI. Not only that: SECO boasts a formidably vast range of modules for different purposes and this, in combination with its customer-first culture, offers a huge choice of options to the client. Most importantly, since 1979 SECO has operated on a global scale in the field of embedded electronics, collaborating with world-class enterprises, institutions and research groups all over the world. It is one of the benchmark companies worldwide in the field of embedded hardware and its reliability is unrivalled.Share this:TwitterFacebookLinkedInMoreRedditTumblrPinterestWhatsAppSkypePocketTelegram Tags: Boards & Modules Continue Reading Previous UIC-compliant IoT gateway platform opens up new possibilitiesNext Defining IoT and Industry 4.0 with embedded systemslast_img read more
