Global climate models (GCMs) are important tools for addressing climate change questions at a global scale. Recent research has attempted to combine outputs from multiple GCMs to quantify uncertainty in regional climate change, which may ultimately inform regional stakeholders and policy-makers. Using a case study, we illustrate a potential path toward improvement in an existing Bayesian formul...

Para nitroaniline (p-Nitroaniline) is an organic compound, used as an intermediate in the synthesis of pharmaceuticals drugs, gasoline and dyes. The present study was attempted to investigate the influence of biofield treatment on p-nitroaniline. The study was performed in two groups i.e., control and treatment. The treatment group was subjected to Mr. Trivedi’s biofield treatment. The control ...

The aim of this study is to evaluate the bioactive compounds in the ethanolic leaf extract of Azima tetracantha by using Gas chromatographyMass Spectrometry (GCMS). Azima tetracantha leaves were collected from Ariyalur District, Tamil Nadu. The dried leaf powder was extracted with the solvent ethanol by using Soxhlet apparatus. One microlitre of the extract was subjected for analysis by GCMS to...

Climate change in Northwest China could lead to the change of the hydrological cycle and water resources. This paper assessed the influence of climate change on runoff in the Manas River basin as follows. First, the temporal trends and abrupt change points of runoff, precipitation, and mean, lowest and highest temperature in yearly scale during the period of 1961–2015 were analyzed using the Ma...
