Research ArticleOpen accessIn the keywordsSmall Business Critical Success/Failure Factors In Developing Economies: Some Evidences From BotswanaZelealem T. Temtime, J. PansiriAlthough the discovery of diamond has propelled Botswana from one of the poorest countries in 1966 to its current economic status as a middle-income country, the country still faces the problems of economic diversification, employment creation, income generation and distribution and poverty alleviation. Governmental and non- Governmental organizations have put many efforts on the development of small and medium Enterprises … …American Journal of Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2004 · 9,324 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDiscovery of a New Thermostable Chitinase from Streptomyces No. 6Xiaowen Que, Yonghong Bao, Qing Liu et al.Chitinases are a class of hydrolases that hydrolyze the β-1, 4-glycosidic bonds between N-acetyl-D-glucosamine (GlcNAc) in chitin. Among chitinases, thermophilic chitinases and thermostable chitinases have received extensive attention in recent years due to their ability to tolerate higher temperatures and maintain enzyme stability for a longer period of time. However, it has previously been observed that not all chitinases are … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 3 · 1 Aug 2024 · 5,117 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPermeability, Strength and Filtration Performance for Uncoated and Titania-Coated Clay Wastewater FiltersMasturi, Silvia, Mahardika Prasetya Aji et al.Problem statement: Wastewater problems continue to be a relevant issue, particularly in urban areas. One promising low-cost material for manufacturing porous ceramics as water filter is clay. Clays can be blended with other materials such as polymers to obtain functional ceramic materials. Approach: Ceramic wastewater filters were fabricated from clay using both sol-gel and simple mixing methods followed by hot-pressing … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 29 Feb 2012 · 8,399 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Mathematical Model of Power System with Thyristor Controlled Series Capacitor in Long Transmission LinePrechanon KumkratugProblem statement: It is becoming increasingly important to fully utilize the existing transmission system assets due to environmental legislation, rights-of-way issues and costs of construction and deregulation policies that introduced in recent years. The Thyristor Controlled Series Capacitor (TCSC) has been proposed for the better control power flow and dynamic performance. The exact long transmission line model consists of the … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 27 Feb 2012 · 6,837 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFractional Calculus Theoretical Evolution for Radiation QuantitiesAmin Al-Okour, Sherin A. Sareireh, Abdullah Ajlouni, Abdul-Wali AjlouniProblem statement: Radiation dosimetry features depend on semi-empirical formulas that lack a strong mathematical framework. This is due to the fact that the microscopic radiation interaction with matter includes energy losses that have never been described properly in quantum mechanics, which deals with conserved energy systems. Approach: Using the recent theory of the quantization of nonconservative systems using fractional calculus. … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 2 Feb 2012 · 6,664 accessesView PDFCite
Research ArticleOpen accessIn the keywordsQuality of Service Policy for IEEE 802.11 Networks with Service Rate Selection based on Fairness IndexLia Toledo Moreira Mota, Alexandre de Assis Mota, Luis Fernando FontolanProblem statement: The IEEE802.11 standard states that all stations have the same probability of accessing the network, but does not consider important parameters such as transmission rates and signal-to-noise ratios. However, these networks present an anomaly that allows a station with a low transmission rate to use the communication channel for a long time. Approach: In this context, this study … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 6,667 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFree Enterprise and Entrepreneurship in Serbia: An Analysis of Motivations, Financing and ObstaclesNina Radojevich-KelleyProblem statement: Entrepreneurship is considered to be a major driving force to economic development throughout the world. Free enterprise is challenging in any country, especially in a developing nation such as Serbia where communism and socialism prevailed for decades. The purpose of this study is to examine entrepreneurship and free enterprise in Serbia as well as the challenges or obstacles … …American Journal of Economics and Business Administration, Vol. 3, Issue 2 · 21 Apr 2011 · 8,051 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Role of Sine and Cosine Components in Love Waves and Rayleigh Waves for Energy Hauling during EarthquakeZainal Abdul Aziz, Dennis Ling Chuan ChingProblem statement: Love waves or shear waves are referred to dispersive SH waves. The diffusive parameters are found to produce complex amplitude and diffusive waves for energy hauling. Approach: Analytical solutions are found for analysis and discussions. Results: When the standing waves are compared with the Love waves, similar cosine component is found in both waves. Energy hauling between waves … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 7,586 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimization of Mix Proportion of High Performance Mortar for Structural ApplicationsCheah Chee Ban, Mahyuddin RamliProblem statement: Mortar mix is a major construction material in fabrication of ferrocement structural elements. However, there have been scarce amount of technical data available on suitable mix proportion to achieve structural grade mortar with specific strength requirement and adequate level of workability for proper placement into construction formwork. Moreover, current practice in ferrocement construction work which uses mortar mix … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 8,819 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Study of the Relationship Between Schooling and Enterprises' Demands for TalentsChien-Hua WangProblem statement: In this study, job vacancies in accountancy were used as examples to explore the relationship between schooling and enterprises’ demands for talents. Data of job vacancies and demands in accountancy from 2005-2009 were obtained from the well-known 1111 Job Bank.
