It is important to determine the impact of global climate change on water resources. In effective use resources, amount required for agricultural irrigation should be planned under these conditions. this study, trend analysis data calculation reference evapotranspiration (ET0) between 2011 and 2020 meteorology station Tekirdag, Turkey was carried out. Analysis in study out according methods Lin...

Abstract It is of great significance to quantitatively evaluate the ecological degradation and restoration Yellow River source area from 2001 2017. Net primary productivity (NPP) core indicator used indicate health terrestrial ecosystems. Based on improved CASA (Carnegie-Ames-Stanford Approach) model MOD17A3 NPP products, 174 measured sample sites were validate simulation results, select with h...

Recently, a novel DNA virus designated SEN virus (SEN-V), which is thought to be related to posttransfusion hepatitis, was discovered. The aim of the present study was to clarify the relationship between SEN-V infection and the development of liver disease. We examined SEN-V from the sera of 21 patients with non-B, non-C hepatocellular carcinoma (HCC) and 13 patients with non-B, non-C chronic l...

The hallmark of transmissible spongiform encephalopathies (TSEs or prion diseases) is the accumulation of an abnormally folded, partially protease-resistant form (PrP-res) of the normal protease-sensitive prion protein (PrP-sen). PrP-sen is attached to the cell membrane by a glycosylphosphatidylinositol (GPI) anchor. In vitro, the anchor and the local membrane environment are important for the ...

INTRODUCTION Torque teno virus (TTV) and SEN virus are circular single-stranded DNA viruses that cause blood-borne infections. The SEN virus (SEN-V) was originally detected in the serum of an injection drug user infected with human immunodeficiency virus (HIV). Recently TTV was discovered as a potential causative agent of non-A-E hepatitis. The aim of this study was to investigate the prevalenc...

Changes in vegetation activity are driven by multiple natural and anthropogenic factors, which can be reflected by Normalized Difference Vegetation Index (NDVI) derived from satellites. In this paper, NDVI trends from 1982 to 2012 are first estimated by the Theil–Sen median slope method to explore their spatial and temporal patterns. Then, the impact of climate variables and human activity on t...
