To assess the extent to which the Nile River Valley has been a corridor for human migrations between Egypt and sub-Saharan Africa, we analyzed mtDNA variation in 224 individuals from various locations along the river. Sequences of the first hypervariable segment (HV1) of the mtDNA control region and a polymorphic HpaI site at position 3592 allowed us to designate each mtDNA as being of "norther...

This article investigated the long-term variation of the boreal summer (JJA) moisture circulation over South China (SC). The total precipitable water (TPW) and moisture convergence over SC have increased obviously, such trend is not a local phenomenon, but the result of large-scale circulation anomaly. In the past few decades, the water vapor transport from southern hemisphere and subtropical w...

Baltic Seaports are a part of the sustainable global transport infrastructure. The main competitors countries in Sea region ports Lithuania, Latvia, and Estonia. all three States important transit corridors, connecting not only East West, but also South North. Periodical investments, modernization, construction new terminals allow Port Klaipeda to successfully compete with neighbouring strive f...

Populations of 10-39 CA1 pyramidal cells were recorded from four rats foraging for food reward in an environment consisting of two nearly identical boxes connected by a corridor. For each rat, a higher-than-chance fraction of cells had similarly shaped spatial firing fields in both boxes, but other cells had completely different fields in the two boxes. The level of correlation of fields in the...

Background. Long-distance truck drivers are at risk of acquiring and transmitting HIV and have suboptimal access to care. New HIV prevention strategies using antiretroviral drugs to reduce transmission risk (early antiretroviral therapy (ART) at CD4 count >350 cells/ μ L) have shown efficacy in clinical trials. Demonstration projects are needed to evaluate "real world" programme effectiveness. ...

The corridor between Oslo and Berlin is by the politicians of the regional authorities in the Scandinavian part of the corridor seen a region with unique qualities and a large innovation and growth potential. In order to explore and develop this potential an Interreg project has been launched. Even though development of transport infrastructure is seen as pivotal in this process, there is a com...

Eastern and Southern Africa has a significant number of major transport corridors that provide trade and mobility for coastal and landlocked countries. In 2008 PPIAF funded the Definition and Investment Strategy for a Core Strategic Transport Network for Eastern and Southern Africa, which examines strategic core transportation networks in the region. The study‟s objective was to diagnose the pr...

North-east India, being a corridor to South-east Asia, is believed to play an important role in transmitting drug resistant Plasmodium falciparum malaria to India and South Asia. North-east India was the first place in India to record the emergence of drug resistance to chloroquine as well as sulphadoxine/pyrimethamine. Presently chloroquine resistance is widespread all over the North-east Indi...

Chinese solar greenhouse (CSG) is universally applied in northern China for producing horticultural products. CSG is characterized by the unbalanced structures with an arched front roof face to the south side and a thick wall as well as back roof in the north side. Such structures affect light distribution in the greenhouse. This study aims to investigate the light distribution properties in CS...
