 Abstract

This is a rare clinical case in a patient who presented bilateral retinal detachment by retinal ora serrata dialysis in both eyes, at the same almost symmetrical location in both retinas, with an insidious evolution due to the lower location of the retinal detachment.

 Abstract

The software like Scilab and maxima leads to many challenges to learn Mathematics. Aims to make both software�s the reference for free numerical computation software.How should the mathematics teaching and learning change to best make use of this software?However, software can be used to help students and teachers to develop Mathematical habits of mind and construct Mathematical ideas in simple way.As mentioned software�s is an easy to use, multipurpose Computer Algebra System, a system of program for symbolic manipulation of mathematical expressions. It uses its own inbuilt programming language designed for symbolic as well as arbitrary-precision numerical computations. The methods and approaches to learn and teach Mathematics must be restructured to include activities that allow students and teachers to experiment and build models to help explain Mathematical ideas and concepts through software�s like Scilab and Maxima.This paper enlightens basic concepts and how to use mathematics in laboratory, this can be used most effectively to help students gather data, and test class problems, modify, and accept or reject conjectures as they think about different Mathematical concepts.

 Abstract

White transparent cadmium selenite nanoparticles for optoelectronic devices were prepared from aqueous solution of cadmium acetate dihydrate and sodium selenite by facile microwave assisted hydrothermal method. The average size of the prepared CdSeO3 nanocrystallite is found to be 20nm. XRD, EDX and FTIR studies confirm the structure and composition of CdSeO3 nanoparticles. The optical band gap energy of the material was estimated to be 4.8eV. Uniform transmittance is observed throughout ultra violet and visible region. PL spectrum of CdSeO3 exhibits a sharp blue emission peak at 439nm. TGA shows that the prepared CdSeO3 nanoparticles are very stable up to 6550C.

 Abstract

This paper present a single source cascaded H-bridge multilevel inverter using switched capacitor. The multilevel inverter consists of some of the series connected H-bridge cells. Where each cell required a separate dc source supply. Whereas in this topology separate dc source is replaced by switched capacitor with single dc source supply. Thus by using this method we can reduce the current spike which is harmful while charging the capacitor and it also provide zero current switching condition for charging the switch. The software used for this experiment is Mat lab/SIMULINK. The simulation result for nine level multilevel inverter using switched capacitor is described.

 Abstract

Zooplanktons which are found in Sambhar Salt Lake are studied in the present paper. A lake is the small body part of the water which is isolated from river or sea. A lake is bigger than ponds in size. There are 4 types of lakes. 1.Temporary lakes 2.Permanent lakes 3. Fresh water lakes 4. Saline lakes Sambhar lake is a saline lake and also biggest lake among all salty lakes of India. Phylum Protozoa, Rotifera and Arthropoda�s various species were found at here. Their numbers were effected with season and environmental changes. Maximum number of zooplanktons which were found related with phylum Arthropoda�s class insecta and only one Water spider was found.

Abstract: India has a road network of more than 4.87 kilometers according to MORTH, Techier Research July 2015 and the second largest road network in the world. Road and highway development is the foundation of infrastructure improvement, enhancing the essential driver to deliver rapid and sustained economic growth in changing technological innovation. It is undoubtedly the lifeblood of the nation that is a never-ending litigation activity in India. Due to rising oil costs and a tighter monetary environment, cement is becoming a more attractive choice for a base company that completely contrasts with conventional bituminous asphalt. The Ministry of Road Transport and Highways in India noted that the advanced society cannot work properly without concrete roads.

 Abstract

Plato�s view of rhetoric is both extensive and influential, and it demands considerable philosophical and interpretive challenges. Even a general reading of his dialogue, the Phaedrus demolishes a common assumption that Plato was entirely antagonistic to the practice of rhetoric. In fact, it reveals that Plato�s discussion of rhetoric is both critical as well as constructive. Further, rhetoric, when practiced correctly, paves the way for knowledge. This paper seeks to elucidate such views of Plato on rhetoric in the light of his dialogue the Phaedrus and show how knowledge has to play an important role in it. Furthermore, important insights are also drawn from his other dialogues, such as the Gorgias and the Republic, wherever necessary. The paper has been structured in following three parts � first, it investigates into the meaning of the term �rhetoric�; second, it examines the concept of �rhetoric� and arguments concerning �rhetoric� from the dialogues, namely the Gorgias and the Pheadrus; third and finally, it draws a number of conclusions and observations following the above discussion.
