                       Domestic violence victims denied justice: state of Roraima fails to investigate, prosecute abusers

      June 21, 2017
      The authorities in the Brazilian state of Roraima are failing to investigate or prosecute domestic violence cases, leaving women at further risk of abuse, Human Rights Watch said in a report released today. The serious problems in Roraima, the state with the highest rate of killings of women in Brazil, reflect nationwide failures to provide victims of domestic violence with access to justice and protection.
      Killings of women rose 139 percent from 2010 to 2015 in Roraima, reaching 11.4 homicides per 100,000 women that year, the latest for which there is data available. The national average is 4.4 killings per 100,000 women—already one of the highest in the world. Studies in Brazil and worldwide estimate that a large percentage of women who suffer violent deaths are killed by partners or former partners.
      Only a quarter of women who suffer violence in Brazil report it, according to a February 2017 survey that does not provide state-by-state data. Human Rights Watch found in Roraima that when women do call police they face considerable barriers to having their cases heard. Military police told Human Rights Watch that, for lack of personnel, they do not respond to all emergency calls from women who say they are experiencing domestic violence. Other women are turned away at police stations. Some civil police officers in Boa Vista, the state´s capital, decline to register domestic violence complaints or to request protection orders. Instead, they direct victims to the single “women’s police station” in the state – which specializes in crimes against women – even at times when that station is closed. Even when police receive their complaints, women must tell their story of abuse, including sexual abuse, in open reception areas, as there are no private rooms to take statements in any police station in the state.
      Not a single civil police officer in Roraima receives training in how to handle domestic violence cases. Some police officers, when receiving women seeking protection orders, take statements so carelessly that judges lack the basic information they need to decide whether to issue the order. Civil police are unable to keep up with the volume of complaints they do receive. In Boa Vista, the police have failed to do investigative work on a backlog of 8,400 domestic violence complaints.

   Is blue growth the beginning or end of a healthier ocean?

March 17th 2015

Across the globe, countries are increasingly looking seaward in search of new economic opportunities, including oil, gas, and mineral extraction from the sea floor, renewable energy development, and biotechnology.
The push to expand this so-called “blue economy" comes at a time when the ecological health of the oceans is seriously degraded. Last year, the Economist"s World Ocean Summit concluded with a resounding consensus that more needs to be done to protect and restore the world"s seas, especially the high seas. Will blue growth help or harm efforts to achieve a healthier ocean ecosystem?
The U.N. has proposed ambitious sustainable development goals relating to ocean health. They include reducing pollution from agriculture run-off, decreasing untreated sewage and solid waste, rebuilding depleted fish stocks, and protecting and restoring natural habitats.
A healthy ocean ecosystem is a public good—both locally and globally. Mangroves, corals, and salt marshes protect  coastal towns from storms. Oceans store carbon and produce oxygen that benefits us all. And areas of high biodiversity support global fisheries and are essential for resilient and productive oceans.
These natural benefits can remain intact if nations encourage—and even require—participants in the blue economy to reinvest the economic capital created from that economy in the natural capital of marine and coastal ecosystems; namely by restoring degraded habitats, protecting healthy ones, and financing blue economy “greening" efforts.
Channeling the new wealth of a growing blue economy into projects that will build a healthier ocean will require new financial tools. For instance, a global ocean trust fund, eco taxes, or user fees could be managed at the global level (say the U.N., World Bank, or the Global Environmental Facility) or even at a regional level, perhaps through existing regional seas organisations.
But for now the blue economy needs to aim higher than merely to do no harm. Converting blue economic capital into blue natural capital can raise all boats and produce a healthier, more sustainable blue economy.

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.
