|Federal contractors on Tuesday began building prototypes of President Donald Trump’s proposed border wall with Mexico http://www.basketballrocketsshop.com/ , hitting a milestone toward a key campaign pledge.
A man is detained by Border Patrol officials as he tries to climb a fence after breaching border fencing separating San Diego from Tijuana, Mexico, Tuesday, Sept. 26, 2017, in San Diego.
Construction of eight models in a remote area of San Diego is about three months behind schedule http://www.basketballrocketsshop.com/Cheap-Tyler-Ennis-Rockets-Jersey/ , held up by losing bidders whose protests were eventually denied. A green tarp hanging on a chain-link fence blocked views of the work, which is expected to last 30 days.
Customs and Border Protection may pick several winners, or none. Roy Villarreal, acting chief of the Border Patrol’s San Diego sector, said another contractor will evaluate each model, which will be up to 30 feet (9 meters) high and 30 feet long.
“It may not result in a singular winner. It may be a combination of designs being implemented http://www.basketballrocketsshop.com/Cheap-Trevor-Ariza-Rockets-Jersey/ ,” Villarreal told reporters next to existing border fencing.
As agents prepared for the news conference, a Mexican man breached the fence, cut his hand and was arrested.
The construction site is about 2 miles (3 kilometers) east of San Diego’s Otay Mesa border crossing at the end of steel-mesh fence that runs from the Pacific Ocean.
San Diego police and the county sheriff’s department have helped set up a “free speech zone” nearby for people to demonstrate. Villarreal said he knew of no organized plans to protest.
Bidding documents say four of the prototypes are to be solid concrete and four are to be made of “other materials.” Trump said Friday that the wall should be see-through, apparently at odds with the initial instructions for solid concrete.
Villarreal said the concrete designs would be built with openings to allow agents to see across the border.
The administration faces several federal lawsuits in San Diego that seek to block the prototypes and plans to replace existing barriers in California.
A complaint filed last week by California Attorney General Xavier Becerra, a Democrat, largely mirrors two others by environmental advocacy groups that allege the administration overstepped its authority to speed up construction of the wall.
At issue is a 2005 law that gave the Homeland Security secretary broad powers to waive dozens of laws for border barriers http://www.basketballrocketsshop.com/Cheap-Tracy-Mcgrady-Rockets-Jersey/ , including the National Environmental Policy Act, Clean Air Act and Endangered Species Act. The lawsuits say that authority has expired.
The administration has not commented directly on the lawsuits. It has issued two waivers since August, the first ones since 2008, on grounds of national security. Both waivers are in California, including one that covers the site of prototype construction.
Funding to extend the wall beyond its distance of 654 miles (1,046 kilometers) is in doubt. Democrats have balked at Trump’s $1.6 billion request to replace 14 miles (22 kilometers) in San Diego and build 60 miles (96 kilometers) in Texas’ Rio Grande Valley http://www.basketballrocketsshop.com/Cheap-Steve-Francis-Rockets-Jersey/ , the busiest corridor for illegal crossings.
Caddell Construction Co. of Montgomery, Alabama, and W.G. Yates & Sons Construction Co. of Philadelphia, Mississippi, were awarded contracts to build one wall of concrete and one of other materials.
Other contracts for concrete prototypes went to Fisher Sand & Gravel Co. of Tempe, Arizona http://www.basketballrocketsshop.com/Cheap-Ryan-Anderson-Rockets-Jersey/ , and Texas Sterling Construction Co. of Houston. Contracts for prototypes of other materials were awarded to KWR Construction Inc. of Sierra Vista, Arizona, and ELTA North America Inc. of Annapolis Junction, Maryland.
CHICAGO, Dec. 14 (Xinhua) -- Doctors at Washington University School of Medicine in St. Louis found that radiation therapy can be used to treat patients with a life-threatening heart rhythm.
They have so far treated five patients who had irregular heart rhythms, called ventricular tachycardia http://www.basketballrocketsshop.com/Cheap-Robert-Horry-Rockets-Jersey/ , at the School of Medicine.
The five patients in the study had undergone catheter ablation procedures and their ventricular tachycardia returned, or they were unable to go through the procedure because of other high-risk medical conditions.
In the three months before treatment with noninvasive radiation therapy, the five patients together experienced more than 6,500 ventricular tachycardia events. The average number of events per patient during this time was 1,315, with a range of five to 4 http://www.basketballrocketsshop.com/Cheap-Pj-Tucker-Rockets-Jersey/ ,312. During the first six weeks following radiation therapy, as the patients were recovering, they experienced a total of 680 episodes. In the one year the patients continued to be followed, they collectively had four events. Two patients didn't experience any episodes at all.
To be specific, of the five patients, one patient aged over 80 died in the first month after treatment of causes unlikely to be related to treatment. The remaining four http://www.basketballrocketsshop.com/Cheap-Nene-Rockets-Jersey/ , all in their 60s, are alive two years after radiation therapy, with two patients living unassisted without ventricular tachycardia.
The single dose of radiation these patients received is on par with what might be given to a patient with an early-stage lung tumor.
The radiation therapy does not take effect immediately. The number of arrhythmia events went down but did not disappear in the first six weeks after treatment, which the doctors characterize as a recovery period. After that six-week period, however, the number of events dropped to almost zero http://www.basketballrocketsshop.com/Cheap-Luc-Mbah-A-Moute-Rockets-Jersey/ , and patients were able to slowly come off medications used to control the arrhythmia.
Doctors are cautious, saying they are still monitoring for long-term side effects of radiation therapy, such as lung scarring and further damage to the heart itself. They emphasized that their use of external radiation to the heart only included very ill patients in end-stage disease who had run out of options. More research is required before doctors might consider this approach fo.
