Checking the vulnerability and vulnerability history of green economy friendly critical infrastructures such as hydroelectric, wind, or solar power control systems is essential part of keeping the security intact. Vulnerability reports are one of the most important security tools for security experts to check vulnerabilities. In this paper over 40,000 vulnerability reports from SecurityFocus's vulnerability database BugTraq are studied and the reports are analyzed accordingly to understand the type of vulnerability contributors, the motivation of the contributors, the trend of most common vulnerability types, and the amount of vulnerability reports over the years. It is shown that most of the vulnerabilities are reported by open source vendors and security organizations. Vulnerability reports are also shown to be decreasing since 2006 and more than 70% of the reported vulnerabilities are contributed by less than 10% of the members. It is also observed that remote code, cross-site, and denial of service vulnerabilities have become dominant vulnerability types reported recently. This research can be used by security system designers and planners to better understand the historical perspective of vulnerabilities. It enables better understanding of vulnerabilities ensuring improved robustness against vulnerabilities. Future work is suggested to extend the analysis to other equally popular vulnerability reporting databases and also add more security measurement parameters. © 2015 IEEE. Source

The objective of present review was to determine the various evaluation tests for controlled porosity osmotic pump tablets. Controlled porosity osmotic pump (CPOP) tablet contains drug, osmogens, excipients in core and a coating of semi permeable membrane with water soluble additives. In CPOP water soluble additives dissolve after coming in contact with water, resulting in an in situ formation of micro porous membrane. CPOP tablets were evaluated for compatibility study, precompression parameters and post compression parameters. The present study gives an idea about various evaluation tests for CPOP tablets. © RJPT All right reserved. Source

This article was written to provide compelling rationales for initiating biotechnology education, and a research and development programme in one technology institute in Ethiopia. As the author wishes to share these with a wider audience, the article is presented in the following way: it begins with a brief history of the traditional and conventional biotechnologies in Ethiopia; and reviews the national status of modern biotechnology. The potential of modern biotechnology to promote national development through its support of endeavours in agriculture, environmental management and rehabilitation, health care and industry/manufacturing is then discussed. Finally, the article lists and discusses the key topics that have to be taken into account while introducing and developing modern biotechnology in Ethiopia. Until a good national policy is produced, the topics could serve as guidelines for institutions engaged in biotechnology and life science research. © 2010 Palgrave Macmillan 1462-8732. Source

Many of today's solar cookers lack energy storage and their applications have been limited to day time use while the sun is shining. In addition these cookers need longer cooking time and are less versatile to users compared with the traditional wood stoves. This article presents tests of a solar stove with and integrated heat storage designed to satisfy a particular need of some east African countries to bake their daily food (Injera). The prototype was tested in the solar laboratories at NTNU and Mekelle University, and presented for community demonstrations in Mekelle. Steam is used as heat carrier between a receiver in the focal point of a concentrating dish and a solar salt based latent heat storage. The stored heat enables users to bake at any time. The storage has a capacity to retain usable thermal energy for about one to two days depending on the amount of insulation. This system can supplement the existing electric and biomass Injera stoves and provide inexpensive and clean energy solution for food preparation. Solar baking provides benefits in terms of human health, environmental strain and high costs associated with biomass fuel. © 2014 IEEE. Source

Hydroxy propyl methyl cellulose (HPMC)/hypromellose is widely used cellulose ether in the development of hydrophilic matrices for the development of various pharmaceutical dosage forms. HPMC is a polymer selected by most formulators as a hydrophilic matrix system probably due to the claim that it gives fast gel formation to control initial drug release. It is nontoxic, ease of compression and high drug loading capacity. It provides the release of drug in a controlled manner and giving maximum utilization of drug. This review gives idea about properties of HPMC, mechanism of drug release, factors affecting release from hypromellose and its application. Source
