Research ArticleOpen accessIn the abstractEffects of Mulberry Fruit Powder in Animal Model of StrokePratchaya Kaewkaen, Terdthai Tong-Un, Jintanaporn Wattanathorn et al.Stroke is the leading cause of death and the important cause of disability worldwide. Presently, the effectiveness of therapeutic strategy is still very limited. Based on the role neuroprotective effect of substance possessing antioxidant effect previously reported, we hypothesized mulberry fruit a substance possessing anti-oxidant activity, might be able to protect against cognitive impairment induced by stroke or cerebral ischemia. … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 3 · 15 Aug 2012 · 9,039 accessesView PDFCite
Research ArticleOpen accessIn the abstractFactors Affecting Profitability of Layer Hens EnterprisesEbraheem Altahat, Ali AL-Sharafat, Mohammad AltarawnehProblem statement: Layer hen enterprises suffer from low profitability or losses in many of developing countries all over the world. Jordan is not an acceptance. Approach: This study aimed at investigating the influence of ten main factors affecting the profitability of layer hen producers. The investigated factors include price of purchased pullet, feed price, cost of labor, cost of veterinary … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 7 Mar 2012 · 9,544 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of an Oxidation Ditch System with a Disc AeratorAbdel Ghaly, Ashley ThistleProblem statement: The oxidation ditch system has been used to treat various types of wastewaters. Several types of aerators are used to supply the treatment process with oxygen. Among these devices, the disc aerator has certain advantages regarding foam generation over the brush and paddle type rotors, but the main disadvantages of this aerator is the limited oxygenation capacity. The … …American Journal of Applied Sciences, Vol. 8, Issue 7 · 24 Jun 2011 · 8,113 accessesView PDFCite
Research ArticleOpen accessIn the abstractPattern Based Communication System and Its Performance Characteristics Compared to the Matched FilteringOzgur Orcay, Berk UstundagProblem Statement: Pattern Based Communication System (PBCS) aims to handle two prominent restrictions in communication lines. These are the inefficient utilization of the bandwidth under the spectrum limitations and sensitivity of the data transmission rate to the variation of Signal to Noise Ratio (SNR). Approach: The key point of PBCS is to construct the optimal communication signals, which consist of … …Journal of Computer Science, Vol. 7, Issue 1 · 16 Dec 2010 · 7,288 accessesView PDFCite
Research ArticleOpen accessIn the abstractReliability Assessment of Buckling Strength for Compressed Cylindrical Shells with Interacting Localized Geometric ImperfectionsJalal El Bahaoui, Abdellatif Khamlichi, Larbi El Bakkali, Ali LimamProblem statement: Elastic cylindrical shells are common structures in the fields of civil engineering and engineering mechanics. These thin-walled constructions may undergo buckling when subjected to axial compression. Buckling limits to large extent their strength performance. This phenomenon depends hugely on the initial distributed or localized geometric imperfections that are present on the shell structure. Localized geometric imperfections result in … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 4 Nov 2010 · 8,320 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Cost Effective and User Friendly Approach to Design Wireline Formation TestsClara Bertolini, Giuseppe Tripaldi, Elena Manassero et al.Problem statement: Wireline formation testing (also named Mini-DSTs) are gaining more and more popularity as a possible alternative to conventional well testing especially where there are major environmental and economical constraints. The increased offshore exploration activity, which often implies highly risky and huge operational costs, makes the conventional well testing less attractive in favor of other technologies that can provide … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 6,665 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Approach for Cooling Electronics Using a Combined Heat Pipe and Thermoelectric ModuleBanjerd Saengchandr, Nitin V. AfzulpurkarThe development of effective cooling systems for microprocessors, specifically for CPU and other computer chips, is greatly important due to growth of high speed performance chips, which operate at elevated heat rates. The same issues apply for adjacent units including RAM and HDD also contributing to overall generation of heat inside computer. Problem statement: Conventional cooling system for desktop PC … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,366 accessesView PDFCite
Research ArticleOpen accessIn the abstractSNL2Z: Tool for Translating an Informal Structured Software Specification into Formal SpecificationMohamed A. Sullabi, Zarina ShukurIn the area of software engineering there have been very few efforts to automate the translation from specifications written in natural language to the formal specification languages. Writing of the specifications in natural language is always depending on context and it is commonly vagueness; this represents the major reasons of the challenge. This paper discusses the design of a tool … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,139 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Modelling of an Industrial Smelter Furnace and Converter Off-gas SystemHelen Shang, Megan Dillabough, Phillip Nelson, Bryan SaltIn smelters, metal ores or concentrates are smelted to reduce a metal oxide to a metal through a series of reactions and processes. In a smelting process, a large amount of off-gas emissions are often generated, which can cause serious environmental and plant hygiene problems if not properly treated. Off-gas systems extract and treat the off-gas emissions, and ensure that … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 7,153 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Packet Marketing Method in DDoS Attack DetectionChanghyun Beak, Junaid Ahsenali Chaudhry, Keonsoo Lee et al.Functionality and availability are one of the main characteristics of internet and hence very inviting for attackers to try to provoke a denial-of-service attack. As the intensity and frequency of DDoS attacks has increased, various preventive mechanisms have also been proposed. One of the most effective defence mechanisms proposed was Path Identification (Pi). This method tracks the packet transmission path. … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 7,076 accessesView PDFCite
