F rom the viewpoint of economic theories, total factor productivity (TFP) is the most important component that leads to economic growth and development. The main purpose of this study was to evaluate the impact of knowledge-based economy on total factor productivity in the member countries of the Middle East and North Africa (MENA) region. For this purpose, the panel data regression analysis ha...

Highly pathogenic avian influenza (HPAI) A(H5N8) viruses that emerged in poultry in east Asia since 2010 spread to Europe and North America by late 2014. Despite detections in migrating birds, the role of free-living wild birds in the global dispersal of H5N8 virus is unclear. Here, wild bird sampling activities in response to the H5N8 virus outbreaks in poultry in the Netherlands are summarise...

Deep CCD exposures of the peculiar supernova remnant CTB 80 in the light of the Hα+ [NII], [SII], [OII], and [OIII] filters have been obtained. These images reveal significant shock heated emission in the area of the remnant. An extended bright diffuse nebula in the south–east part of CTB 80 overlaps soft X-ray emission from ROSAT but it does not appear to be related to the remnant under study....

lmost ten years after the end of the Cold War was declared, the Asian North-East continues being an area of convergence between the tensions that were characteristic of that historical period. Disposed around the Korean Peninsula, Russia, China and Japan interact there, with the USA constantly interfering in the political and military spheres. The Peninsula continues being divided between two r...

The genome of a virus isolated from an outbreak of foot-and-mouth disease (FMD) in Morocco in 2015 is described here. This virus is classified as lineage Ind-2001d within serotype O, topotype ME-SA (Middle East-South Asia). This lineage is endemic on the Indian subcontinent but has caused outbreaks in the Middle East and North Africa since 2013.

The causes of natural variation in alkalinity in the North Pacific surface ocean need to be investigated to understand the carbon cycle and to improve predictive algorithms. We used GLODAPv2 to test hypotheses on the causes of three longitudinal phenomena in Alk*, a tracer of calcium carbonate cycling. Thesephenomenaare (a)an increase fromeast towestbetween45°Nand55°N, (b) an increase fromwest ...

Forty two Paleocene benthic foraminiferal species of the Midway Formation in the Gulf Coastal Plain of Texas, USA were firstly investigated by Plummer (1927), and its paleogeographic distribution in some other countries in the Tethyan province were recorded: North America (USA, Mexico), South America (Argentina), Europe (North Sea Basin, Spain, France, Italy, Czech Republic, Bulgaria), North Af...

Dr. James Clay Moltz is Assistant Director and Research Professor at the Center for Nonproliferation Studies of the Monterey Institute of International Studies. He has published widely on Russian Far Eastern and East Asian security issues. The rise of theater ballistic missile capabilities in East Asia—particularly in China and North Korea—has raised fears among the United States, South Korea, ...

We examine the response of Arctic gas and aerosol concentrations to perturbations in pollutant emissions from Europe, East and South Asia, and North America using results from a coordinated model intercomparison. These sensitivities to regional emissions (mixing ratio change per unit emission) vary widely across models and species. Intermodel differences are systematic, however, so that the rel...
