Comprehensive In silico Analysis of Single Nucleotide Polymorphisms (SNPs) in Human BDNF Gene
Abstract: Since a number of single nucleotide polymorphisms (SNPs) are associated with the BDNF gene mutations involved in different diseases. Hence, it is important to find out the probable functional SNPs before planning a larger population study. So, to look out for the functional nsSNPs (non-synonymous single nucleotide polymorphisms) in BDNF gene, existing data present in the dbSNP database and different bioinformatics tools like SIFT, PolyPhen, nsSNPAnalyzer, F-SNP, I-mutant, Pymol were …

Statistical Analysis of Geomagnetic Activity and Solar Activity Features during Solar Cycle 23 & 24
Abstract: We present a statistical analysis of the geomagnetic storm (GMSs) with the solar activity features (Sunspot number (SN), H-α flare and coronal mass ejection (CME)) during solar cycle 23 and 24. Sunspot number (SN) shows good correlation with peak values of GMSs indices (correlations coefficient R= 0.76) while CME(R=0.59) and H-α (R=0.55) show moderate correlation. So we conclude that GMSs have good correlation with solar activity features during major geomagnetic …

Precipitation Trend Analysis by MK Test in Garhwal Region Districts of Uttarakhand (1901–2010)
Abstract: Climate change has disrupted the major climatic parameters at a global level. However, the changes having localized intensity are not equal for all regions especially in India. These changes must be quantified locally to manage the natural water resources more effectively. Precipitation is one of the most important climatic parameters. It has been widely measured as a starting point towards the apprehension of global climate change. The purpose of this …
