In vitro gas production, nutrient digestibilities and metabolisable energy (ME) values of fresh and conserved pangola grass (Digitaria eriantha Steud., synonym D. decumbens) were studied in 16 cross-bred (Thai native. ×. Merino) sheep. The study was designed as a completely randomized design with Napier grass (Pennisetum purpureum) as a control and pangola grass in fresh, hay and silage forms with the same cutting age (45 days growth) as treatments. Chemical composition of forages and faeces was determined and used to estimate nutrient digestibility. In vitro gas production was recorded at 3, 6, 8, 12, 24, 48, 72, 84 and 96. h of incubation and used to estimate the kinetics of gas production. Chemical composition was relatively constant across treatments. Likely due to the addition of 5% sugarcane molasses before ensiling, pangola grass silage had higher (P <. 0.05) nutrient digestibilities and ME concentrations than the other forages when estimated from in vivo digestibility and in vitro gas production. Cumulative gas production at 12, 24, 48 and 96. h of incubation was highest (P <. 0.05) in pangola silage followed by fresh pangola, pangola hay and Napier grass, in that order. In conclusion, pangola grass in fresh or conserved forms has a high potential to deliver energy and protein through forage and can be recommended as a nutrient source for small ruminants. © 2015 Elsevier B.V.

This study employed the wavelet empirical orthogonal function (WEOF) analysis to analyse the nonstationary variability of rainfall in Ethiopia and global sea surface temperature (SST) for 1900-1998. The study found that the nonstationary variations of both the June to September (JJAS) and February to May (FMAM) Ethiopian rainfall can be delineated into three zones: western half of Ethiopia north of the Great Rift Valley (GRV), southern Ethiopia south of the GRV and the GRV from southwestern Ethiopia to the Afar Triangle. The leading wavelet principal component (WPC) signals showed that Ethiopian rainfall had been in stagnation for most of 1900-1998, with major droughts in the 1940s and 1980s. The dominant frequencies of Ethiopian rainfall ranged between 2 and 8years. In western Ethiopia, the 2-4-year rainfall frequencies dominated the rainfall variation, but their trends are modulated by 5-7-year frequencies, whereas in the Afar Triangle, the 5-7-year frequencies were dominant. Between 1900 and 1998, the Afar Triangle region experienced decreasing rainfall for 60years (1900-1960). The seasonal global SST revealed that regardless of what time of the year, the strongest contributions to global SST variations occur in the Antarctic Ocean, the ElNiño region of South America and in the southwestern Pacific Ocean, followed by the Atlantic and the Indian Oceans. Further, this study also shows annual migrations of SST variations in the ElNiño region, the Antarctic and the Atlantic Oceans. The leading SST signal variations show that SST warming started in the Atlantic and Indian Oceans, from 1950 to 1975, and spread to the Antarctic Ocean between 1960 and 1990, which probably contributed to the melting of sea ice. Teleconnections between WPC1 of Ethiopian rainfall and SST scale-averaged wavelet power were found for the ElNiño region and northern Atlantic, west of the Sahara desert. © 2013 Royal Meteorological Society.

The Arctic policy of the United States has remained broadly constant over the years since the early 1970s, when initial efforts to craft a unified U.S. government inter-agency approach to the Arctic were reviewed. It has been based on several key principles, which include the protection of our national security interests and the preservation of the principle of freedom of the seas and superjacent airspace, as well as the development and implementation of programs and activities to facilitate international cooperation in the areas of exploration, scientific research, resource development, exchange of scientific and technical data and the engagement of indigenous and local communities. The past two decades have witnessed an evolutionary trend and growth in United States perspective to welcome greater structured international and multilateral cooperation, which has resulted in more cohesion and better communication among Arctic countries.

Mobile health (mHealth) technologies have the potential to greatly impact health research, health care, and health outcomes, but the exponential growth of the technology has outpaced the science. This article outlines two initiatives designed to enhance the science of mHealth. The mHealth Evidence Workshop used an expert panel to identify optimal methodological approaches for mHealth research. The NIH mHealth Training Institutes address the silos among the many academic and technology areas in mHealth research and is an effort to build the interdisciplinary research capacity of the field. Both address the growing need for high quality mobile health research both in the United States and internationally. mHealth requires a solid, interdisciplinary scientific approach that pairs the rapid change associated with technological progress with a rigorous evaluation approach. The mHealth Evidence Workshop and the NIH mHealth Training Institutes were both designed to address and further develop this scientific approach to mHealth. Copyright © Taylor & Francis Group, LLC.

In an effort to provide easier access to voter information, the Office of the Secretary of State and Alabama Interactive announced on April 22 that they will be launching a new online portal. This portal will include voter information and access to voter history, not limited to county school districts, county commission districts and state house districts. "We are very excited to be able to offer this service to the citizens of Alabama," said Secretary John Merrill. "This new feature continues my efforts to increase transparency and will allow any interested citizen, candidate or elected official to be able to custom prepare and purchase the voter list they desire without having to contact another person to do it. The system will be secure, cost-efficient, and provide easy access to the available information." The Secretary of State already offers certified business documents, foreign LLC filings and certificates of existence. The development of this online portal will expand its offerings with voter data. However, official election results, poll lists and information pertaining to official election preparation will not be accessible through the portal, which can be accessed at www.alabamainteractive.org. Alabama is not the first state to offer this type of portal with voter information. Minnesota, Louisiana and South Dakota are just some of the many states to introduce these types of resources for residents throughout their respective areas. Voter information portals are designed to make it simpler for residents to access critical information, such as whether they are registered to vote. While the Alabama portal does not offer city wide of municipal district voter information, some portals do offer additional insight. Louisiana's portal, for instance, allows individuals to hone in on voter information down to an address level. Individuals who want to use Alabama's portal to purchase voter information online will be charged one cent per voter list information online. The price isn't steep, and it provides users with the transparency they desire when it comes to everything related to voting in Alabama. For safety and security purposes, provisions are in place to protect victims, as well as the parents of victims of domestic violence, under Code of Alabama 1975, Section 17-4-33(b). Any questions can be directed to the Office of the Secretary of State. © 2016 Tech Times, All rights reserved. Do not reproduce without permission.
