In this study we have used analytical approach called Reconstruction of Variational Iteration Method to investigate unsteady nanofluid flow between two moving parallel plates. The effect of Graphene-Oxide (GO) nanoparticles solid volume fraction on temperature and velocity profiles have been discussed through some plots. The effect of moving parameter on velocity profiles have been shown for cases plates moving apart and moving together. Nusselt number have been achieved for various type of nanoparticles, solid volume fraction and Eckert number. It has been understood that by changing the solid volume fraction in constant Eckert number heat transfer enhancement will be achieved. The comparison of current solution with numerical one assures us about validity and accuracy of solution.

VSK separator is an advanced air classifier with combinations of static and dynamic cyclones. In the present study, an attempt has been made to minimize wet and dry processes for upgrading of sillimanite by using VSK separator. It is observed from the VSK classifier experimental study, which by using a multi stage VSK separator unit the maximum sillimanite grade of 48.1% with 20.9% recovery has been achieved at 800 rpm screw feeder speed, 800 rpm cage wheel speed and 45 Hz air rate. At these optimum conditions, sillimanite concentrate (50.6% grade) has been achieved from the feed sample containing 46.5% grade sillimanite.

This paper deals about the basic concept of reliability evaluation and optimization on any system. The paper also briefs about the possibility to create a set of global standards and specification indices along with geographical and technological boundaries across the system. This review paper also shows that the investigation related to reliability applies to any branch of engineering by utilizing the mathematical tools and careful analysis. Further studies are in progress.

An Overview On Evaluation Of Biological Activity Of Quinazoline Based Heterocycles

Pallavi Jain

Assistant Professor, Department of chemistry, SRM University, Modinagar, Ghaziabad, 201204, India



This paper reveals about the quinazolines, benzaimides and thiazolidinediones which comprise diverse therapeutically potent applications in the field of medicinal chemistry and synthetic applications in the field of the organic chemistry. This paper briefly reviews an appropriate balance between the broad spectrum pharmacological profile and synthesis of drugs that should be economical, harmless and environmental friendly.

With the idea in mind, it is projected in the present work to synthesize various series of quinazolines, benzaimides and thiazolidinediones based, pyrimidines, thiazoles. This study is expected to hopefully produce analogues with better biological profiles and with the minimal requirement to maintain the activity.

Keywords: Biological activity, drug, quinazolines, benzaimides and thiazolidinediones

Enterprise Resource Planning Software in Public Institutions: Mapping Based Internship Management Portal

Mehmet Rüştü Mercan, Fatih Çelik

Department of Computer Engineering, Technology Faculty Sakarya University Esentepe Campus/ Sakarya



ERP (Enterprise Resource Planning) Systems are the software for management of all business processes in an integrated portal. Even though ERP Systems are used in a wide range of private sector, researches are being conducted about these system’s applicability on public sector too. For this purpose, ERP Software Companies make research and developments for new modules applicable for Public Sector. Nowadays, because of few solutions exist per public sector needs and their being extremely expensive, public institutes head for different software solutions for different departments. In this work, a web based portal applicated is designed for the tracking and management of internship at firms, which plays a vital importance for Vocational High Schools.

Keywords: ERP, Web Based Applications,  Enterprise Systems, Software, Management portal
