Thomas effectively seals his first Tour de France title

first_imgBritain’s Geraint Thomas, wearing the overall leader’s yellow jersey reacts as he crosses the finish line during the twentieth stage of the Tour de France cycling race, an individual time trial over 31 kilometers (19.3 miles) with start in Saint-Pee-sur-Nivelle and finish in Espelette, France, Saturday, July 28, 2018. (AP Photo/Christophe Ena)ESPELETTE, France — No longer merely a support rider for Chris Froome, Geraint Thomas is going to Paris in the yellow jersey.The Welshman with Team Sky effectively sealed his first Tour de France title by protecting his lead in the time trial on the penultimate stage on Saturday.ADVERTISEMENT Report: Disney dropping the ‘Fox’ from movie studio names “The strongest guy has won this Tour de France,” Froome said. “Tomorrow, to stand up on the podium with G, it’s going to be a really proud moment for me.”Thomas, known as “G,” was a support rider during Froome’s title rides but he became Sky’s undisputed leader when Froome cracked in the grueling 17th stage through the Pyrenees.Thomas and Froome have been together since their days on the small Barloworld team a decade ago.“Because we’ve been teammates and friends for so long, it made it easier to communicate honestly,” Froome said. “It was clear as soon as we hit the Alps that Geraint was in better physical condition than me. It was pretty simple, really.”Wearing an all-yellow skin suit on a bike in the red, white and blue colors of the British flag, Thomas was the last rider to start.ADVERTISEMENT Lacson: Calamity fund cut; where did P4 billion go?

Still, he was first at the two checkpoints before slowing in the final kilometers.“I felt strong. I felt really good, actually. I heard I was up and maybe I was pushing it a bit hard on some of those corners,” Thomas said. “Nico (Portal, Sky sports director) told me to relax, take it easy and just make sure I won the Tour. And that’s what I did.”At the finish, Thomas let out a loud scream and held his arms out wide in celebration. He embraced his wife, Sara Elen, as soon as he got off his bike.“The last time I cried was when I got married,” Thomas said as he teared up.Thomas is poised to become the third British rider — and first Welshman — to win the Tour after Bradley Wiggins and Froome. He will make it Sky’s sixth victory in the last seven years.“It’s insane really — just all the interest in Cardiff,” Thomas said. “Great to put it on the map. We’re a small nation and we really get behind anyone that’s successful. By the sounds of it, it’s gone pretty crazy back home, so looking forward to going back to celebrate.”An all-around rider who began his career on the track, Thomas helped Britain to gold medals in team pursuit at the 2008 and 2012 Olympics before turning his full attention to road racing.Thomas claimed the yellow jersey by winning Stage 11 in the Alps, followed that up with another victory atop Alpe d’Huez a day later, and defended his advantage through the Pyrenees.“He was in the shape of his life,” Dumoulin said. “He didn’t make any mistakes. He was never put into trouble by anyone, in the mountains or anywhere — including by myself.”The time trial world champion, Dumoulin clocked under 41 minutes over the hilly and technical 31-kilometer (19-mile) route.

CRMA facilitated over 1000 jobs for youths in 2017

first_img– 700 registered in 2018The Central Recruitment and Manpower Agency, under the auspices of the Ministry of Social Protection, registered some 2000 job-seekers drawn from Regions Two, Three, Four, Five, Six and Ten for 2017. One thousand of those registered were provided jobs.Most persons seeking jobs are between ages 15 and 35, Chief Recruitment and Manpower Officer Valarie Moore told the Department of Public Information (DPI). She said that for 2018 (January to March), some 700 persons registered for jobs, about 200 of which were placed in jobs.Moore explained that for January alone, the agency saw a total of 95 persons, while in February some 169 persons registered. These numbers, she said, do not include those that are already in the system awaiting job placement.“We have a term we call submission, which means sending someone to take part in interviews. And so sometimes that number will be more than the registration that we have, but we normally look at those persons in the system already,” Moore added.For those persons with two and three subjects at Caribbean Secondary Examination Council (CSEC) and little or no skills, Moore said the call centres usually take off those persons.Moore noted that they advise persons on where they can go to improve their qualifications and get assistance. They also share with job-seekers what are some of the benefits of obtaining a skill and/or academic qualifications.The agency also collaborates with the Board of Industrial Training (BIT), which provides training for unqualified individuals through the Government Technical Institute (GTI) and the Guyana School of Agriculture.However, she said that sometimes some of the youths do not need jobs, but need advice, or in some cases public assistance. Those persons are referred to the Woman of Worth (WOW) and the Sustainable Livelihood and Entrepreneurial Development (SLED) programmes under the Ministry of Social Protection.The Central Recruitment and Manpower Agency is a division of the Social Protection Ministry. It registers applicants for employment, taking specific note of their occupational qualifications, experiences, and desires. It evaluates, if necessary, their physical and vocational abilities. Its objective is to place individuals seeking jobs in suitable employment, while providing career guidance and counselling. The Agency was established by the Government of Guyana in October 1944.last_img read more

Vidal wants move as Juventus issue ultimatum – Man United transfer update

first_img1 It has quickly progressed from speculative interest to full-blown saga, but there appear to be glimpses of light at the end of the tunnel with Arturo Vidal’s protracted transfer to Manchester United reportedly on the way to reaching its conclusion.But what has changed? Here’s the latest…Ultimatum issuedJuventus look to be growing tired of the pantomime that is Vidal’s future and have finally put their foot down, issuing an ultimatum to the Chilean to make his mind up by August 15. According to Italian outlet La Stampa, Juve want to have enough time to recruit a replacement if necessary and are instead leaving the decision up to the player and his agent. They continue that a deal will be on their terms, suggesting at a transfer fee of €50m.Contract ‘agreed’ as talks continueThe Independent claim that Vidal’s agent has agreed a £182,000-a-week deal with Man United, and that the decision of whether to finally make the switch now rests with the player and Juventus. They point out that Vidal is yet to shed any real light on his thoughts, opting to remain largely silent instead. However, with Juve placing a timeframe on his protracted move, he will have to break his stance soon.He wants United moveThe Express report that Vidal has told close friends that he wants to move to Manchester, following Juventus’ ultimatum. United have reached a ‘broad agreement over personal terms’ the publication reports. Vidal has travelled with Juve on their pre-season tour of Asia, but it looks as though he will be leaving the camp early in order to finalise his reported £47m move.Five-year dealDespite their apparent concerns over a long-standing knee injury, it seems as though Man United are prepared to commit to a long-term deal for Vidal, with the Star reporting that the Red Devils have offered the midfielder a five-year deal. Echoing reports elsewhere, they confirm that the deal will be worth £182,000-a-week with the transfer fee likely to be around £47m.Man United fans, do you think you’ll managed to land Arturo Vidal?

L.A. gains 44 million pounds

first_imgLos Angeles County adults have gained an average of 6 pounds each over the past eight years – for a total of 44 million pounds – increasing the risk of contracting life-threatening illnesses, says a study released today by the health department. At the current rate of weight gain, the study predicted that 25 percent – or of every four adults in the county – will be obese by 2010 and that the effects may start to decrease life expectancy by two to five years. “This could reduce two centuries of increases in life expectancy,” said Dr. Jonathan E. Fielding, the county health officer. “We need to stop this terrible epidemic. And we haven’t seen the worst of it because of the lag time. “This translates into big increases in diabetes, heart disease, stroke, muscular-skeletal problems and maybe an increase in some cancers.” Building on advances in providing LAUSD students with healthier vending-machine beverages and snacks, officials are working on increasing the amount of physical activity and health education in the schools. “There are state mandates around physical education in the schools, but whether they are really followed, I don’t know,” said Dr. Francine Kaufman, director of the Comprehensive Childhood Diabetes Center at Children’s Hospital Los Angeles. “There are also mandates on what is taught in health classes. The question is, who is delivering those messages and are we really turning out children with health literacy?” Health experts note a variety of factors behind the obesity epidemic, including more sedentary lifestyles, more opportunities to eat and a lack of food labeling at restaurants. “You can’t walk 20 yards without a snacking opportunity,” Fielding said. “We have gotten into patterns of consuming portions that are not healthful. “All-you-can-eat is not in the interest of your health.” Troy Anderson, (213) 974-8985 To help fight obesity, health officials recommend: 30 to 60 minutes of daily moderate physical activity such as walking, swimming, biking, dancing or gardening. A healthy breakfast. Parents eating meals with their children. Reading food labels and buying foods that are low in fat, cholesterol and salt and high in fiber. Drinking less soda and high-sugar juice drinks. Limiting television and video games to less than two hours a day and avoiding eating in front of the TV. Eating two cups of fruit, 2 cups of vegetables and three servings of whole grain each day. 160Want local news?Sign up for the Localist and stay informed Something went wrong.

An estimated 29 percent of Latino adults is obese, compared with 28 percent of African-Americans, 17 percent of whites and 6 percent of Asians. Of even greater concern, officials said, is a finding that the percentage of overweight middle school children rose from 18 percent in 1999 to nearly 22 percent in 2003. “If this trend continues, then one out of three kids could be overweight by 2010,” Fielding said. “We’re robbing our children of bright futures if we don’t focus on stopping this and reversing it. We are setting them up for so many problems later in life.” The county Department of Health Services is joining today with the city and Los Angeles Unified School District officials in a Leadership for Healthy Living Forum in Elysian Park designed to address the issue and develop possible solutions. last_img read more

World’s Fastest Men Ready To Race In Drake Relays 100 Meters

first_imgDES MOINES, Iowa – The most exciting 10 seconds in track & field will live up its billing at Drake Stadium when the men’s invitational 100 meters makes its return to the Drake Relays presented by Hy-Vee.Blake Boldon, the Franklin P. Johnson Director of the Drake Relays, has announced the full field for the event that will be headlined by Canadian Olympic medalist Andre De Grasse. However, De Grasse is just one of five Olympians in the eight-competitor field that will race down the homestretch of the Blue Oval April 28 at 2:56 p.m. Six of the event’s eight lanes will feature competitors has shattered the 10-second mark in the event.In 2016, De Grasse won three medals at the Rio Olympics, including bronze in the 100 meters behind Usain Bolt. With Bolt’s retirement, De Grasse is thought by many in the track and field community to be the heir apparent to the title ‘World’s Fastest Man.’In addition to that bronze medal in the 100 meters, De Grasse won silver in the 200 meters behind Bolt and bronze in the 4×100-meter relay as a member of the Canadian team. He has run the 100 meters in 10 seconds or less in a legal wind nine times in his career, including a personal best of 9.91 and has run as fast as 9.69 with a tailwind. De Grasse’s Blue Oval debut marks the first time an invitational 100 meters has been staged at the Drake Relays presented by Hy-Vee since 2005.Joining the cadre of elite sprinters is a local favorite that had a storied career at Drake Stadium as a collegian. Brandon Carnes, a two-time Relays champion in the event as a collegian at UNI, will race as a professional for the first time at Drake Stadium. The 16-time Missouri Valley Conference champion owns a personal best of 10.06.Another competitor who made his mark a collegian returns as an experienced professional in Isiah Young. Young was an Olympic semifinalist in the 200 meters in 2012 and has been a member of three World Championship teams for the United States. While competing for the University of Mississippi, Young was a four-time Drake Relays champion and back-to-back winner of the 100 meters in 2012 and 2013. The second of those titles earned him Drake Relays Most Outstanding Performer honors and is one of three collegiate competitors to win the honor outright in the last decade.Mike Rodgers is one of the veterans in the field that has run a sub 10-second 100 meters a staggering 39 times in his career and owns the 14th fastest time in the history of the event at 9.85. He has been a five-time World Championship semifinalist and led off the USA’s 4×100-meter relay in the 2016 Olympics.Joining De Grasse among the international talent in the event is Turkey’s national record holder, Jak Ali Harvey. Harvey was the 2016 European Championship silver medalist in the event and finished seventh in the 2017 World Championship. With a personal best of 9.92, he qualified for the 2016 Olympics in the 100 meters, 200 meters and 4×100-meter relay.Kemar Hyman’s 9.95 best in the event makes him the national record holder for the Cayman Islands and he has twice represented his country in the Olympics and has experience on the Blue Oval while winning an NCAA Championship for Florida at Drake Stadium.Thursday’s announcement of the 100-meter field brings the total number of Olympians set to compete at the Drake Relays presented by Hy-Vee to 16 to date with dozens more to be announced in the coming weeks.All-session, multi-session and single-session tickets are currently on sale via the Drake Athletic Ticket Office and Friendly Versionlast_img read more

Placing a Concrete Foundation on Rigid Foam Insulation

first_imgA rugged subslab vapor barrierA cross-laminated plastic vapor barrier was specified. We installed a StegoWrap membrane, 15 mil thick product. All lap joints and seams were sealed with the tape provided by the manufacturer. Typical pipe and conduit penetrations were sealed with tape also. Where penetrations were ganged too closely together to allow detailing with the tape, mastic was used to seal the vapor barrier to the piping/conduit. This is an accessory product offered by the vapor barrier manufacturer. Where the vapor barrier intersects with footings at the building perimeter, a special butyl tape was used to seal the vapor barrier to the footing. This seal was important to provide air barrier continuity between the slab-on-grade assembly and the exterior wall assembly.It turned out that we were very fortunate to have moved the vapor barrier to the top side of the foam insulation since it rained heavily for a few days in early August. The rain didn’t create any serious water problem as most of it ran off to the edges of the slab area, and what remained dried off relatively quickly. If the vapor barrier had been placed over the gravel, below the insulation, we could have had a major issue on our hands with water retained in the foam insulation layer.A 4-inch-thick concrete slab was placed on top of the vapor barrier. We paid close attention to the concrete mix design. We utilized a mix design from CalPortland with a 0.42 water-cement ratio, as was specified. When pouring a concrete slab directly over a plastic vapor barrier, the use of a low water-cement ratio mix design is important to help minimize slab curling and also to minimize the potential for moisture-related problems with floor finishes applied over the slab. Four inches of EPS is the right amountOnce the team actually started believing this could work, the next concern became how much insulation to use. Together, we landed on the idea of 4 inches of EPS foam, based on a sense this would provide a good balance of cost and constructability. In particular, we were trying to avoid the thicker levels of insulation that have been used on some Passivhaus buildings.Throughout the design process, PHPP iterations were run that looked at using more or less foam foundation insulation; yet the team kept coming back to the 4 inch foam layer. We looked at the relationship of the foundation R-value to changes in other envelope parameters such as the wall R-value, the window U-factor, and the roof insulation. After numerous iterations, the 4 inch foam thickness was agreed to by the team.So, how does this work? The foam is placed under the entire slab on grade and wraps around and underneath the footings at the building perimeter. The 4 inch foam thickness is reduced to 1 inch at bearing wall locations, resulting in a thickened slab with reinforcement, to serve as footings for those walls at the building interior.Due to the seismic design of the project, there are several large, deep footings that serve as the base for hold-downs to resist high lateral loads on the building. These deep footings were actually poured such that the slab insulation runs continuously over the top of the footing. As designers and builders working on the Orchards at Orenco multifamily project in Hillsboro, Oregon, we’re getting our feet wet with Passivhaus design for the first time. Our collective common sense suggested that we should be suspicious of this idea. Nearly all of the building’s structural loads are placed on the footings and it strikes many people as possibly a fool’s errand to place building footings on foam.However, after extensive research it became clear there is a long history of using certain types of very high density expanded polystyrene (EPS) foam insulation underneath major structural works of all kinds, including roadways, bridges, and runways. Our concerns receded based on the evidence and we were swayed — yet still reserved and cautious. The caution persists to this day and will follow us until this is a well-established building practice, without significant drawbacks. Coordinating with subcontractorsAs clearing and grubbing began at the site, and then the initial excavation activities, the construction team began a detailed coordination process. To properly construct a high-performance Passivhaus design, diligent, proactive coordination of the work is required of the general contractor. There is no substitute for diligence when it comes to this coordination. Even a highly developed and accurate set of design documents does not include all the information needed to build the project, and inevitably there will be some gaps in documentation or a need to modify a detail slightly, or in a major way, to achieve the design intent while accommodating construction variables such as sequencing of the work, manufacturer’s installation instructions, etc.Coordination of the work is fundamental to all construction projects, but the need is heightened when executing a Passivhaus design, especially when it comes to the detailing of the airtight and thermal-bridge-free building envelope. For example, at some detail conditions there could be four or more trades that impact the airtightness of the building since they each supply and/or install components that are integral to the air barrier system.An important duty of the general contractor is to actively communicate with the entire group of subcontractors, to let them know about the Passivhaus and requirements on the project, and to educate them about key issues that may impact their scopes of work and the overall Passivhaus certification. Due to the intricacies involved with material specifications and detailing of the Passivhaus design, communication with the subcontractors that impact the building envelope needs extra attention.On the Orchards project, a full day Building Envelope Coordination (BEC) meeting was held on site during the first month of construction, to gather together all the envelope-related subcontractors and key suppliers and review project requirements, including specifications, detailing, schedule, sequence of trades, etc.Scheduling this meeting very early during construction allowed the team to work through any gaps or inconsistencies in the scopes of work of various trades, as well as any issues related to the design documents. Upon completion of the BEC meeting, resolved issues were addressed readily and efficiently through the project submittal process. Issues that needed further examination or design work were addressed through the project Request for Information (RFI) process. The coordination work touched all major elements of the design, including the foundation, exterior walls, windows and doors, and the roof. The concrete contractors were hesitant to place concrete footings on rigid foamTo move forward from this point we had to overcome a little hesitation from the concrete crew. They’d never prepped a concrete foundation to go on top of insulation before. This idea raised more than a few eyebrows. After explaining the purpose of the foam layer below the footings and slab, resistance was overcome, if only temporarily.To construct the footings at the building perimeter, 4 inches of Type IX EPS foam were placed on top of the gravel base, the foam was informally tested to ensure solid contact with the base, formwork was constructed on top of the foam, and then concrete was placed. After initial set and curing, the formwork was stripped and EPS was applied to the vertical face of the footing.Upon completion of the initial footing work at the building perimeter, preparations for the slab on grade were made. A capillary break layer with 6 inches of clean crushed gravel was placed over the rock working pad and compacted to a dense state. A radon mitigation system was installed on top of the gravel base. The system includes 4-inch perforated flexible piping wrapped in filter sock material and embedded in an additional layer of gravel, 6 inches thick, placed on top of the compacted gravel base. The gravel provides a minimum 1 inch cover over the piping.Four inches of Type II EPS foam was placed on top of the gravel base. The design documents indicated a single layer of foam; however the crew pushed to use two layers of 2-inch foam for the installation. The crew believed the foam would lay flatter and provide more stability on the gravel base going with the two layers. This also had the advantage of allowing for staggered joints in the boards and eliminate direct heat flow paths that would occur at butt joints in the boards had we used only one layer, as is typical with roof insulation installation. The foam was trimmed to fit tightly around penetrations. Any gaps were filled with expanding spray foam sealant.For the most part, the slab insulation went down well over the gravel base; however, there were a few issues with getting the foam to lie flat and stable. These issues were resolved by reworking the gravel. The geotechnical engineer called for 2”- ¼” gravel whereas a smaller rock or pea gravel would have helped to eliminate the issues we encountered. It should go without saying that any high-performance building should be built on a solid foundation. So why would we set our building on a layer of foam insulation?The answer, of course, is to limit thermal bridging. Those bridging effects can cause a significant amount of heat loss through the mass structure at the base of the building. By thermally isolating the building foundation from the ground, building performance is improved, not only from an energy performance standpoint but also in terms of comfort and moisture management. Does the StegoWrap vapor barrier go above or below the rigid foam?An important concern that arose during the coordination process was the location and detailing of the subslab vapor barrier. The vapor barrier was not clearly indicated in the architect’s details, although a vapor barrier had been specified. In the slab on grade assembly drawing, the vapor barrier was indicated to be installed below the slab insulation. The Walsh team questioned this location, given our concern that a large amount of water could collect in the slab insulation layer if it should rain prior to a slab pour. The configuration of insulation and vapor barrier essentially created a sealed “bathtub” that could hold a lot of water. Not a good scenario!Even though we were in the dry summer months in Portland, there is always a chance of rain. When we pointed this out, the architect understood the concern and agreed with relocating the vapor barrier to the top of the slab insulation. Furthermore, the detailing of the vapor barrier at the foundation perimeter was not clear in the design drawings. We discussed this with the architect and sorted out the termination details as part of the coordination process, working with the vapor barrier manufacturer’s standard details and sealing products. With these details resolved, construction on the building foundation began. We put rigid foam under the footingsIn some high-performance building circles, it has become common to place a layer of insulation under a slab on grade. This is especially the case in colder climates. What’s new with Passivhaus design is the idea of completely isolating the building foundation from the ground, not only under the slab, but also under the footings.
