Microbial decolouration of azo dyes: a review.

Gallbladder cancer is a malignancy of biliary tract which is infrequent in developed countries but common in some specific geographical regions of developing countries. Late diagnosis and deprived prognosis are major problems for treatment of gallbladder carcinoma. The dramatic associations of this orphan cancer with various genetic and environmental factors are responsible for its poorly defined pathogenesis. An understanding to the relationship between epidemiology, molecular genetics and pathogenesis of gallbladder cancer can add new insights to its undetermined pathophysiology. Present review article provides a recent update regarding epidemiology, pathogenesis, and molecular genetics of gallbladder cancer. We systematically reviewed published literature on gallbladder cancer from online search engine PubMed (http://www.ncbi.nlm.nih.gov/pubmed). Various keywords used for retrieval of articles were Gallbladder, cancer Epidemiology, molecular genetics and bullion operators like AND, OR, NOT. Cross references were manually searched from various online search engines (http://www.ncbi.nlm.nih.gov/pubmed,https://scholar.google.co.in/, http://www.medline.com/home.jsp). Most of the articles published from 1982 to 2015 in peer reviewed journals have been included in this review.

LncRNA HOXA-AS2 and its molecular mechanisms in human cancer.

Discharge of untreated domestic and industrial wastewater into aquatic bodies is posing a serious eutrophication threat, leading to a slow degradation of the water resources. A number of physical, chemical and biological methods have been developed for the treatment of wastewaters; among these, the use of microalgae is considered as a more eco-friendly and economical approaches. Microalgae are versatile organisms which perform multiple roles in the environment—bioremediation of wastewater, gleaning of excess nutrients and in turn, generate valuable biomass which finds applications in the food, biofuel and pharmaceutical industries. They are currently being utilized to reduce the high nutrient load (especially N and P) from wastewaters, which fulfill the growth requirements of microalgae, making it a suitable cultivation medium for biomass production. The present review represents a comprehensive compilation of reports on microalgal diversity of wastewaters, followed by a critical overview of their utilization, suitability and potential in bioremediation vis-a-vis biomass production. This review also emphasizes the superiority of polyalgal and consortial approaches in wastewater treatment, as compared to the use of unialgal inocula, besides providing useful pointers for future research needs in this area.

A Threshold Voltage Model for the Short-Channel Double-Gate (DG) MOSFETs with a Vertical Gaussian Doping Profile

In this paper, a strong inversion drain current model incorporating various effects such as channel length modulation has been developed for a short-channel symmetrical triple material -- double gate (TM-DG) MOSFET based on the drift current equation. The model results have been compared with the simulation data obtained by using the commercially available device simulation software ATLAS.

An Analytical Drain Current Model for Short-Channel Triple-Material Double-Gate MOSFETs

In this work, a recent device structure called double-gate (DG) nanoscale RingFET has been investigated by developing a computationally efficient foremost semianalytical threshold voltage model. Poisson’s equation has been solved using parabolic approximation to calculate surface channel potential, which has been further employed to formulate the threshold voltage of the device. This device comes under the category of edgeless transistor, which has a lot of scope in radiation harsh environment-based applications. A cutoff frequency of terahertz range up to 1.1 THz has been observed in this device, which makes it very useful for high-frequency applications. The proposed model results are extensively verified with the simulation data obtained with a three-dimensional technology computer-aided design (3D TCAD) simulator from SILVACO ATLAS™. Both the modeled and simulated results are found to be in good agreement.
