 Surface Modified Calotropis Gigantea Fiber Reinforced Polypropylene Composites
Authors : Haydar U. Zaman,Ruhul A. Khan,


In this article, the effects of chemical treatment (sodium dodecyl sulfate, SDS, and SDS pretreated benzoyl chloride) on the physicomechanical, morphological, and weather tests of calotropis gigantea fiber (CGF) reinforced polypropylene (PP) composites were investigated. The outcomes show that CGFs act as reinforcing fillers enhancing the physicomechanical properties (e.g. tensile strength,...

Theoretical and Simulation Investigation for Create Optical Buffer in Semiconductor Optical  Ring Resonators
Authors : Abdolkarim Afroozeh,


In the framework of the nonlinear waveguide, we investigate propagation of solitons with in optical ring resonators. We show how the complicated nonlinear interplay slow light solitons in the MRRs to the possibility to create optical buffer. Dynamical control over slow-light solitons is realized via a controlling field generated by bright soliton. We provide an analytical description for the...

 Influence of Inhomogeneity Properties of Multilayer Structure on Density Field-Effect Heterotransistors in a Conventional Energy Efficient Double Tail Dynamic Comparator
Authors : E.L. Pankratov,


In this paper we introduced an approach to increase integration rate of element of a conventional energy efficient double tail dynamic comparator. We formulate recommendations for optimization of annealing to decrease dimensions of field-effect heterotransistors and to increase their density. At the same time one can decrease transition area between doped and undoped areas of elements of the...

Kinetic Study of Acid Hydrolysis of Corn Cob to Xylose
Authors : B.N. Uzoh,O.E. Onyelucheya,J.C. Obijiaku,


Corn cob is one of the common renewable, cheap and abundant lignocellulosic materials. As a potential source of fermentable sugars, corn cob can be used as a substrate for value added products such as xylitol. This research paper studied the production of xylose from corn cob using phosphoric and nitric acids at 1300C, and acid concentrations of 1wt%, 2wt%, 3wt%, 4wt% and 5wt% respectively, and...

 Obese Gut Microbiome with High Cholesterol Diet  Accelerates Obesity in Zebrafish, Danio rerio (Hamilton 1822)
Authors : C. Justin David,G. Adaikalaraj,


Obesity is a multifactorial disorder induced by a combination of genetic and environmental factors, characterized by chronic accumulation of adipose tissue. Dietary lipids significantly contribute to obesity but regulation of energy homeostasis may be altered by resident gut microbiome. Altering or transplanting gut microbiome may lead to harmful or beneficial effects in humans. Zebrafish has...
