Effect of 2D-EBG Structure on Monopole Antenna Radiation and Analysis of Its Characteristics
Abstract: In this paper, we present a two dimensional electromagnetic (2D-EBG) square shaped mushroom structure placed between two monopole antennas. Two artificial properties of this 2D-EBG structure such as PMC and Band Reject Region are investigated here. The radiation characteristics of a monopole antenna over this, 2D-EBG structure is tested by considering two cases. In the first case monopole antenna is made to operate within band rejection region where as in …

2D-QSAR Studies on Unsaturated 4-Azasteroids as 5α-reductase Inhibitors
Abstract: Dihydrotestosterone (DHT) a major circulating male hormone is produced by NADPH dependent enzyme 5α-reductase (5 alpha R) and has been found to be causative agent in the development of pathological condition i.e. benign prostate hyperplasia (BPH). Thus inhibition of 5α-reductase enzyme represents a novel target in the treatment of BPH. Present study describes the relationship between the 5α-Reductase inhibitory activity for structurally related unsaturated 4-azasteroids derivatives and their physicochemical descriptors …

Assessment of Magnitude and Associated Factors of Adverse Birth Outcomes among Deliveries at Suhul Hospital Shire Tigray, Ethiopia from September, 2015 to February, 2016
Abstract: An adverse birth outcome is common phenomena both in developed and underdeveloped countries. Among all these adverse birth outcomes prematurity, low birth weight and stillbirth are the most common cases. Each year, about 15 million babies in the world, more than one in 10 births, are born too prematurely. More than 7% of those babies die shortly after birth; countless others suffer from lifelong physical, neurological, or educational disabilities, often …

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 …

Computational Identification of Protein Tyrosine Phospatase-1B (PTP-1B) Inhibitors for Checking Type II Diabetes
Abstract: Protein tyrosine phosphatases (PTPs) are a family of enzyme that comprises of about 100 proteins which catalyze dephosphorylation of phosphotyrosine residues in protein substrates. Phosphotyrosine is a central element in cell signaling, and its activity is essential for cellular homeostasis and for appropriate responses to extracellular signals. PTP-1B antagonizes insulin signaling by reducing the activation state of the insulin receptor kinase, thereby inhibiting post-receptor signaling in insulin responsive tissue. The …
