Libya has been beset by chaos since its long-serving ruler Col Muammar Gaddafi was ousted in 2011.

Visitors with low-emitting, fuel-efficient vehicles can pull into a preferred parking spot closer to the front entrance, where a U.S. Green Building Council seal proclaims the hotel's status as LEED Platinum — a rating reserved for the most energy-efficient of buildings. In my loft-like room on the Promixity's top floor, with its stunning floor-to-ceiling windows, exposed concrete walls and towering ceiling, a card on the plush king-size bed details more of the hotel's Earth-loving ways. The furniture... Читать дальше...

Former President Barack Obama is entirely too dignified to get on a world stage and say that President Donald Trump is a completely inept hell spawn who wears dive goggles when he paints his skin burnt sienna. Obama will never say that the current president is a divisive heel who is so far in the deep end that he…

Abstract: Passive microwave observations from various spaceborne sensors have been linked to the soil moisture of the Earth's surface layer. A new generation of passive microwave sensors are dedicated to retrieving this variable and make observations in the single theoretically optimal L-band frequency (1-2 GHz). Previous generations of passive microwave sensors made observations in a range of higher frequencies, allowing for simultaneous estimation of additional variables required for solving the...

Abstract: This paper reviews university-level efforts to improve understanding of anthropogenic global climate change (AGCC) through curricula that enable student scientific inquiry. We examined 152 refereed publications and proceedings from academic conferences and selected 26 cases of inquiry learning that overcome specific challenges to AGCC teaching. This review identifies both the strengths and weaknesses of each of these case studies. It is the first to go beyond examining the impact of specific... Читать дальше...

Abstract: Over the past 15 years, the northeastern United States has seen a statistically significant increase in the frequency of extreme precipitation events that is larger and more widespread than anywhere else in the country. This increase in events is more likely to be associated with frontal and low-pressure systems, rather than being caused by more tropical cyclones impacting the region.

The hardening of America's borders is an essential part of Trump's agenda. But will this make the United States a safer and more prosperous nation? Hear from Jamil Dakwar, Sana Mustafa, Yael Eiesenstat, Oz Sultan, and Chadwick Moore. This program is part of the Shades of Red and Blue series, presented by The Ethics Centre, and co-sponsored by the Carnegie Council for Ethics in International Affairs and Bard Globalization and International Affairs program. This program was recorded on April 1, 2017.

Can Congress achieve real spending cuts without a credible cap on total spending? Jonathan Bydlak of the Coalition to Reduce Spending has some ideas.

Abstract: The shortwave infrared (SWIR) bands on the existing Earth Observing missions like MODIS have been designed to meet land and atmospheric science requirements. The future geostationary and polar-orbiting ocean color missions, however, require highly sensitive SWIR bands (greater than 1550nm) to allow for a precise removal of aerosol contributions. This will allow for reasonable retrievals of the remote sensing reflectance (R(sub rs)) using standard NASA atmospheric corrections over turbid... Читать дальше...

A community preservation organization in the Chelsea section of Manhattan in New York City has done its part to make sure the city’s last Underground Railroad site remains standing and is restored to its original design.

Abstract: Capturing and quantifying the world in three dimensions (x,y,z) using light detection and ranging (lidar) technology drives fundamental advances in the Earth and Ecological Sciences (EES). However, additional lidar dimensions offer the possibility to transcend basic 3-D mapping capabilities, including i) the physical time (t) dimension from repeat lidar acquisition and ii) laser return intensity (LRI?) data dimension based on the brightness of single- or multi-wavelength (?) laser returns.

Abstract: This presentation highlights advanced environmental barrier coating (EBC) and SiC-SiC Ceramic Matrix Composites (CMC) systems for next generation turbine engines. The emphasis will be placed on fundamental coating and CMC property evaluations; and the integrated system performance and degradation mechanisms in simulated laboratory turbine engine testing environments. Long term durability tests in laser rig simulated high heat flux the rmomechanical creep and fatigue loading conditions will... Читать дальше...

Abstract: Limits and guidelines are set on microbial counts in produce to protect the consumer. Different agencies make specifications, which constitute when a product becomes unsafe for human consumption. Producers design their procedures to comply with the limits, but they are responsible creating their own internal standards. The limits and guidelines are summarized here to be applied to assess the microbial safety of the NASA Veggie Program.

Abstract: Space missions rely utterly on metallic components, from the spacecraft to electronics. Yet, metals add mass, and electronics have the additional problem of a limited lifespan. Thus, current mission architectures must compensate for replacement. In space, spent electronics are discarded; on earth, there is some recycling but current processes are toxic and environmentally hazardous. Imagine instead an end-to-end recycling of spent electronics at low mass, low cost, room temperature, and... Читать дальше...

At this moment, the idea that we’re on the brink of electric cars becoming cheaper to build than combustion cars is getting a lot of traction, along with the idea that EVs will be as cheap to own as the loud kind of car even sooner. These are important developments, and while it’s potentially good news for consumers,…

Abstract: Vibration testing of James Webb Space Telescope OTIS on the new vibration facility at Goddard Space Flight Center.

Abstract: Flash technology is being utilized in fuzed munition applications and, based on the development of digital logic devices in the commercial world, usage of flash technology will increase. Digital devices of interest to designers include flash-based microcontrollers and field programmable gate arrays (FPGAs). Almost a decade ago, a study was undertaken to determine if flash-based microcontrollers could be safely used in fuzes and, if so, how should such devices be applied. The results were...

Abstract: NASA awarded Small Business Innovative Research (SBIR) contracts to AdvR, Inc to develop a high generation rate source of entangled photons that could be used to explore quantum key distribution (QKD) protocols. The final product, a photon pair source using a dual-element periodically- poled potassium titanyl phosphate (KTP) waveguide, was delivered to NASA Glenn Research Center in June of 2015. This paper describes the source, its characterization, and its performance in a B92 (Bennett... Читать дальше...
