With Brazil in Turmoil, Rio Counts Down to Olympics
By REBECCAR. RUIZAPRIL27, 2016
RIO DE JANEIRO- Brazil's president is facing impeachment. The country's economy is in sharp decline. Bodies of water that will be used for Olympic competitions are polluted, and global public health officials are trying to tamp down the Zika virus epidemic.
With less than 100 days before the Olympic Games come to South Amarica for the first time, Rio de Janeiro faces more than the usual challenges that bedevil host cities, like delayed stadium construction and transportation concerns. (Rio has those, too.) The mood here, however, is hardly one of panic. Officials in charge of executing the Summer Games say they feel insulated from Brazil's turmoil at this late stage. The Olympics, after all, tend to exist in their own bubble, elaborately coordinated to ensure that the multibillion-dollar operation goes off smoothly. "The machine is in place, and it's relatively stable," Ricardo Leyser, Brazil's sports minister, said in an interview this week. "My biggest concern isn't any individual issue. lt's the small demands that all come at once."
Local organizers are beginning to lay colorful comforters patterned with the silhouettes of cartoon cyclists, fencers and swimmers - on the twin beds in the athletes' village. They are monitoring the growth of 14-month-old grass that will be transplanted to Maracanã, the storied soccer stadium that will also be used for the opening and closing ceremonies. They are pulling trash from Guanabara Bay, where the Games' sailing events will be held; mopping up standing water to minimize mosquito breeding; and ramping up a round-the-clock security operation - all while publicly expressing little worry about the unrest encircling them.
On Wednesday, with the handoff of the Olympic flame in Greece and the start of a journey that in little more than a week will bring it to Brazil, the official countdown to the Aug. 5 opening ceremony began.
ln Rio, the race to be ready is intensifying, with construction workers here still laboring on mass transit projects that were key promises seven years ago in the city's bid to host the Games. Costing several billion dollars, those projects include a new subway line and express bus lanes that connect the Olympic Park in Barra da Tijuca to the rest of the city, which is expected to swell with more than half a million visitors.
As the value ofthe Brazilian real has drastically declined overthe last year, some have expressed doubt that the transit projects will materialize beyond the sleek, modernist weather shelters that have been built at various stations. At a news conference Wednesday, the city's secretary of transportation said the new routes would be ready i n ti me but did not specify when. To the vast majority of people watching the Games on television, however, such infrastructure may not matter.
The permanent venues for competitions here are mostly complete - all but those for tennis and track cycling - and athletes from around the world have competed in dozens of test events in Rio in recent months. "lt's about the filling of the cake," Mr. Leyser said. "lt's not about the stadiums; it's about the scoreboards."
As ofthe latest counts, 62 percent ofthe 5.7 million tickets on the market had been sold - roughly half of the total tickets for the Olympics - and 24 percent of tickets available for the Paralympics had been sold. But compareci with past Olympics, the buyers of those tickets may be disproportionately international, saidAndrew Parsons, the presidentofthe Brazilian Paralympic Committee.
For some Brazilians, the country's political and economic crises have cast a shadow on the celebration. President Dilma Rousseff's ouster looks increasingly likely amid a sweeping graft scandal, and those in line to succeed her have their own controversies hanging overthem.
Questions of corruption have extended to Olympics planning, particularly after a businessman who worked on many Olympic projects in Rio was convicted of corruption and money laundering related to separata contracts. Mr. Leyser said that the questions centered on irregularities at the Deodoro event site and that no publicofficial had been accused ofwrongdoing. "lt's more an administrativa issue than a corruption scheme," he said. "lt's basically a question ofthe numbers." Mr. Leyser called the devaluation of Brazil's currency an opportunity because it increases the buying power of foreign money coming into Brazil forthe Games.
But not everyone sees the event as a boon to the country. Shirlei Alves, who lives in the Santa Marta favela of Rio, criticized the government for spending on the Olympics in the face of Brazil's problems.
"The world is just getting worse here," Ms. Alves said, noting that she was without medication and electricity. "The government is making a mistake. l'd like if they'd take a better look at the poor people and not help people who are already rich." Eduardo Paes, the mayor of Rio, said Wednesday that the city had a "comfortable financial situation" and had spent on stadium construction 1 percent ofwhat it spent on health education. "I know people are skeptical," Mr. Paes said, citing the "huge deliverables" for the Olympics. "Of course the situation here has been difficult. But there is a commitment of the Brazilian state to deliverthe Olympics."
Perhaps the most vexing issue for local organizers-the one that may stir anxiety among athletes and spectators - is the mosquito-borne Zika virus, which has been linked to birth defects and temporary paralysis. Zika is of greater concern outside Rio, in the far north part of Brazil, but the World Health Organization has declared the virus a global public health emergency and has advised pregnant women notto travei anywhere in Brazil.
"The Olympics is a pretty effective way of taking whatever disease is local and making it global," said Ashish K. Jha, director ofthe Global Health lnstitute at Harvard.
Some scientists have suggested that by the time the Olympics start in August - wintertime in Brazil, when mosquitoes are less numerous - the virus might be more prevalent in the southern United States.
"Zika's been spreading effectively on its own, but there's very good reason to think the Olympics will accelerate the spread," Dr. Jhasaid.
But the virus poses a unique problem because it isso far beyond the contrai of local organizing officials, and so many questions about it remain unanswered. Few athletes have publicly expressed concern, but it is unclear how many might withdraw as the Games draw closer.
"At this point you just keep going," David Wallechinsky, an Olympics historian, said. "You have to continue as if everything's going to be fine. These are real concerns - Zika, the water quality. But even if Dilma is forced out of office, it's not going to stop the Olympics."

Mount Roraima, a Mystified Hiking Experience
Hiking here is not hard and you can also get help from the indigenous population, as they organize tour guides in exchange for a small sum of money. If you are on your own however, try to reserve at least four days for this fantastic journey, as there are plenty of things to see and enjoy up there. Mount Roraima is said to have some of _____________________ hiking trails in the world.
You should not leave after 2 p.m. from the village as trekkers are no longer allowed after this hour. At the beginning of your climb, your baggages will be strictly checked and you can not take more than 15 kilos with you. So careful how you organize things. Being given that this is a national park , you are not permitted to take rocks or plants along the way.
The top of the mountain measures 2772m, it offers amazing landscapes and establishing a tent around here is possible. However, you should know the weather changes suddenly in this area so be prepared.

NASA Researchers Studying Advanced Nuclear Rocket Technologies
January 9, 2013
By using an innovative test facility at NASA’s Marshall Space Flight Center in Huntsville, Ala., researchers are able to use non-nuclear materials to simulate nuclear thermal rocket fuels - ones capable of propelling bold new exploration missions to the Red Planet and beyond. The Nuclear Cryogenic Propulsion Stage team is tackling a three-year project to demonstrate the viability of nuclear propulsion system technologies. A nuclear rocket engine uses a nuclear reactor to heat hydrogen to very high temperatures, which expands through a nozzle to generate thrust. Nuclear rocket engines generate higher thrust and are more than twice as efficient as conventional chemical rocket engines.
The team recently used Marshall’s Nuclear Thermal Rocket Element Environmental Simulator, or NTREES, to perform realistic, non-nuclear testing of various materials for nuclear thermal rocket fuel elements. In an actual reactor, the fuel elements would contain uranium, but no radioactive materials are used during the NTREES tests. Among the fuel options are a graphite composite and a “cermet” composite - a blend of ceramics and metals. Both materials were investigated in previous NASA and U.S. Department of Energy research efforts.
Nuclear-powered rocket concepts are not new; the United States conducted studies and significant ground testing from 1955 to 1973 to determine the viability of nuclear propulsion systems, but ceased testing when plans for a crewed Mars mission were deferred.
The NTREES facility is designed to test fuel elements and materials in hot flowing hydrogen, reaching pressures up to 1,000 pounds per square inch and temperatures of nearly 5,000 degrees Fahrenheit - conditions that simulate space-based nuclear propulsion systems to provide baseline data critical to the research team.
“This is vital testing, helping us reduce risks and costs associated with advanced propulsion technologies and ensuring excellent performance and results as we progress toward further system development and testing,” said Mike Houts, project manager for nuclear systems at Marshall.
A first-generation nuclear cryogenic propulsion system could propel human explorers to Mars more efficiently than conventional spacecraft, reducing crews’ exposure to harmful space radiation and other effects of long-term space missions. It could also transport heavy cargo and science payloads. Further development and use of a first-generation nuclear system could also provide the foundation for developing extremely advanced propulsion technologies and systems in the future - ones that could take human crews even farther into the solar system.
Building on previous, successful research and using the NTREES facility, NASA can safely and thoroughly test simulated nuclear fuel elements of various sizes, providing important test data to support the design of a future Nuclear Cryogenic Propulsion Stage. A nuclear cryogenic upper stage - its liquid- hydrogen propellant chilled to super-cold temperatures for launch - would be designed to be safe during all mission phases and would not be started until the spacecraft had reached a safe orbit and was ready to begin its journey to a distant destination. Prior to startup in a safe orbit, the nuclear system would be cold, with no fission products generated from nuclear operations, and with radiation below significant levels.
“The information we gain using this test facility will permit engineers to design rugged, efficient fuel elements and nuclear propulsion systems,” said NASA researcher Bill Emrich, who manages the NTREES facility at Marshall. “It’s our hope that it will enable us to develop a reliable, cost-effective nuclear rocket engine in the not-too-distant future."
The Nuclear Cryogenic Propulsion Stage project is part of the Advanced Exploration Systems program, which is managed by NASA’s Human Exploration and Operations Mission Directorate and includes participation by the U.S. Department of Energy. The program, which focuses on crew safety and mission operations in deep space, seeks to pioneer new approaches for rapidly developing prototype systems, demonstrating key capabilities and validating operational concepts for future vehicle development and human missions beyond Earth orbit.
Marshall researchers are partnering on the project with NASA’s Glenn Research Center in Cleveland, Ohio; NASA’s Johnson Space Center in Houston; Idaho National Laboratory in Idaho Falls; Los Alamos National Laboratory in Los Alamos, N.M.; and Oak Ridge National Laboratory in Oak Ridge, Tenn.
The Marshall Center leads development of the Space Launch System for NASA. The Science & Technology Office at Marshall strives to apply advanced concepts and capabilities to the research, development and management of a broad spectrum of NASA programs, projects and activities that fall at the very intersection of science and exploration, where every discovery and achievement furthers scientific knowledge and understanding, and supports the agency’s ambitious mission to expand humanity’s reach across the solar system. The NTREES test facility is just one of numerous cutting-edge space propulsion and science research facilities housed in the state-of- the-art Propulsion Research & Development Laboratory at Marshall, contributing to development of the Space Launch System and a variety of other NASA programs and missions.

Today at Facebook’s press event, Mark Zuckerberg, CEO of Facebook, announced its latest product, called Graph Search.
Zuckerberg made it very clear that this is not web search, but completely different.
He explained the difference between web search and Graph Search. “Web search is designed to take any open-ended query and give
you links that might have answers.” Linking things together based on things that you’re interested in is a “very hard technical problem,”
according to Zuckerberg.
Graph Search is designed to take a precise query and give you an answer, rather than links that might provide the answer.” For
example, you could ask Graph Search “Who are my friends that live in San Francisco?”
Zuckerberg says that Graph Search is in “very early beta.” People, photos, places and interests are the focus for the first iteration of the
product.
Facebook Graph Search is completely personalized. Tom Stocky of the search team explains he gets unique results for a search of
“friends who like Star Wars and Harry Potter.” Then, “If anyone else does this search they get a completely different set of results. ...C...
someone had the same set of friends as me, the results would be different [because we have different relationships with our friends].”
You can also use Graph Search for recruiting. Stocky says if he was looking for people to join the team at Facebook, he could search
for NASA Ames employees who are friends with people at Facebook. “If I wanted to reach out and recruit them, I could see who their friends
are at Facebook. To refine them I can look for people who wrote they are “founders.”
Photos is another big part of Graph Search. Results are sorted by engagement so you see the ones with the most likes and comments
at the top. For example, Lars Rasmussen, Facebook engineer, searched for “photos of my friends taken at National Parks.” He got a gorgeous
page of photos from Yosemite, Machu Pichu, and other parks.

By Michelle Singletary, Published: January 15, 2013
It’s not nice to tell people “I told you so.” But if anybody has the right to say that, it’s Nina E. Olson, the national taxpayer advocate.
Olson recently submitted her annual report to Congress and top on her list of things that need to be fixed is the complexity of the tax
code, which she called the most serious problem facing taxpayers.
Let’s just look at the most recent evidence of complexity run amok. The Internal Revenue Service had to delay the tax-filing season so it
could update forms and its programming to accommodate recent changes made under the American Taxpayer Relief Act. The IRS won’t start
processing individual income tax returns until Jan. 30. Yet one thing remains unchanged − the April 15 tax deadline.
Because of the new tax laws, the IRS also had to release updated income-tax withholding tables for 2013. These replace the tables
issued Dec. 31. Yes, let’s just keep making more work for the agency that is already overburdened. Not to mention the extra work for
employers, who have to use the revised information to correct the amount of Social Security tax withheld in 2013. And they have to make that
correction in order to withhold a larger Social Security tax of 6.2 percent on wages, following the expiration of the payroll tax cut in effect for
2011 and 2012.
Oh, and there was the near miss with the alternative minimum tax that could have delayed the tax filing season to late March. The AMT
was created to target high-income taxpayers who were claiming so many deductions that they owed little or no income tax. Olson and many
others have complained for years that the AMT wasn’t indexed for inflation.
“Many middle- and upper-middle-class taxpayers pay the AMT, while most wealthy taxpayers do not, and thousands of millionaires pay
..A.. income tax at all,” Olson said.
As part of the recent “fiscal cliff” deal, the AMT is now fixed, a move that the IRS was anticipating. It had already decided to program its
systems on the assumption that an AMT patch would be passed, Olson said. Had the agency not taken the risk, the time it would have taken to
update the systems “would have brought about the most chaotic filing season in memory,” she said in her report.
The tax code contains almost 4 million words. Since 2001, there have been about 4,680 changes, or an average of more than one
change a day. What else troubles Olson? Here’s what:
− Nearly 60 percent of taxpayers hire paid preparers, and another 30 percent rely on commercial software to prepare their returns.
− Many taxpayers don’t really know how their taxes are computed and what rate of tax they pay.
− The complex code makes tax fraud ..B.. to detect.
− Because the code is so complicated, it creates an impression that many taxpayers are not paying their fair share. This reduces trust
in the system and perhaps leads some people to cheat. Who wants to be the sucker in this game? So someone might not declare
all of his income, rationalizing that millionaires get to use the convoluted code to greatly reduce their tax liability.
− In fiscal year 2012, the IRS received around 125 million calls. But the agency answered only about two out of three calls from
people trying to reach a live person, and those taxpayers had to wait, on average, about 17 minutes to get through.
“I hope 2013 brings about fundamental tax simplification,” Olson pleaded in her report. She urged Congress to reassess the need for
the tax breaks we know as income exclusions, exemptions, deductions and credits. It’s all these tax advantage breaks that complicate the
code. If done right, and without reducing revenue, tax rates could be substantially lowered in exchange for ending tax breaks, she said.
