An important motivation for AMMA is the major regional scale and multi-decadal West African drought. It started at the end of the 1960’s, and was particularly severe in the seventies and eighties (Figure 1). It is indeed considered as the strongest observed event of rainfall variability at these time and space scales, and the actual mechanisms accounting for this drought are yet to be precisely...

The 4th IPCC report summarises the effects on precipitation for Europe based on global climate models (GCM) simulations as follows: In northern Europe the climate will become moister – especially during winter – and the Mediterranean region will be much drier in the future – especially for the summer months than it is today. Central Europe lies in the transition region between these two regimes...

The two human cell lines HepG2 from hepatoma and HMCL-7304 from striated muscle were γ-irradiated with doses between 0 and 4 Gy. Abundant γH2AX foci were observed at 4 Gy after 4 h of culture post-irradiation. Sham-irradiated cells showed no γH2AX foci and therefore no signs of radiation-induced double-strand DNA breaks. Flow cytometry indicated that 41.5% of HepG2 cells were in G2/M and this r...

This paper analyses current precipitation rates (PRs) and trends over the Mediterranean Sea region and their response to global climate change scenarios. The analysis uses 0.25° gridded PRs dataset over a 13-year period (1998– 2010) based on remote sensing data from the Tropical Rainfall Measuring Mission. Future scenarios use the results of six global climate models (GCMs) under four represent...

A variety of lac resin samples obtained from artists' suppliers, industrial manufacturers, and museum collections were analysed using gas chromatography mass spectrometry (GCMS) and reactive pyrolysis GCMS with quaternary ammonium reagents. These techniques allowed a detailed chemical characterisation of microgram-sized samples, based on the detection and identification of derivatives of the hy...

General circulation models (GCMs), the climate models often used in assessing the impact of climate change, operate on a coarse scale and thus the simulation results obtained from GCMs are not particularly useful in a comparatively smaller river basin scale hydrology. The article presents a methodology of statistical downscaling based on sparse Bayesian learning and Relevance Vector Machine (RV...

We examine the evidence for the possibility that 21st-century climate change may cause a large-scale "dieback" or degradation of Amazonian rainforest. We employ a new framework for evaluating the rainfall regime of tropical forests and from this deduce precipitation-based boundaries for current forest viability. We then examine climate simulations by 19 global climate models (GCMs) in this cont...

BACKGROUND Inflammation has been implicated in many disorders, including cancer and available therapies elicit adverse effects. Plants of the family Rubiaceae have shown potency against inflammation. The anti-inflammatory and anti-oxidant potential of Feretia apodanthera was investigated in this study to evaluate its effectiveness. METHODS The phytochemical, antioxidant and anti-inflammatory ...

Lakes, either artificial or natural, are greatly important as a component in their catchments’ hydrology, but also ecosystem service providers. However, due to climate change, they have begun face numerous problems with water quality and quantity. Furthermore, general circulation models (GCMs) show future change reduction rainfall increase temperature. The aim of the current study is present an...
