Research ArticleOpen accessIn the abstractApplying Software Engineering Methodology for Designing Biomedical Software Devoted To Electronic InstrumentationGilsa Aparecida de Lima Machado, Patricia Mara Danella Zacaro, Alderico Rodrigues de Paula Junior, Marcelo Lopes de Oliveira e SouzaProblem statement: Significant effort goes into the development of biomedical software, which is integrated with computers/processors, sensors and electronic instrumentation devoted to a specific application. However, the scientific work on electronic instrumentation controlled by biomedical software has not emphasized software development, instead focusing mainly on electronics engineering. The development team is rarely composed of Software Engineering (SE) experts. Usually, a … …Journal of Computer Science, Vol. 8, Issue 10 · 23 Aug 2012 · 6,976 accessesView PDFCite
Research ArticleOpen accessIn the abstractReversal of Attitude: The Influence of Counter-Attitudinal InformationPauline Dibbets, Laura Adolphs, Ingeborg Close et al.Problem statement: Research has shown that both positive and negative information can alter a neutral attitude towards an unknown person, with negative information having, in general, a larger impact. Though this positive-negative asymmetry has received considerable attention, it has, to our knowledge, not been tested in more current and powerful social media, such as youtube. Although attitudes are not fixed, … …Journal of Social Sciences, Vol. 8, Issue 3 · 12 Jun 2012 · 9,021 accessesView PDFCite
Research ArticleOpen accessIn the abstractSociocultural Characteristics of Psychological Education in the Context of Systemic-Anthropological ApproachIrina Loginova, Victoria Chupina, Yulya ZhivaevaProblem statement: The problem of moving from economic efficiency of the social one in the modern society is actualized. It is pointed out that the methodological basis for the solving questions of psychological education development are considered to be an anthropological psychology as a new scientific branch, which reflects the tendencies of development of psychology now a days. It is … …Journal of Social Sciences, Vol. 8, Issue 2 · 26 Mar 2012 · 8,869 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeneralization of Boolean Functions Properties to Functions Defined over GF(p)Saad Elmansori, B. E. EsamProblem statement: Traditionally, cryptographic applications designed on hardware have always tried to take advantage of the simplicity of implementation functions over GF(p), p = 2, to reduce costs and improve performance. On the contrast, functions defined over GF(p); p > 2, possess far better cryptographic properties than GF(2) functions. Approach: We generalize some of the previous results on cryptographic Boolean … …Journal of Computer Science, Vol. 8, Issue 6 · 13 Mar 2012 · 7,442 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetic Diversity of Some Saudi Barley (Hordeum Vulgare L.) Landraces Based on Two Types of Molecular MarkersMohamed Abdel Hamid Mohamed El-Awady, Adel Ahmed El-Sayed El-Tarras, Salah El-Din El-AssalProblem statement: Very little is known about the genetic diversity and morphological variability present in barley landrace in KSA, a country experiencing loss of biodiversity because of replacement of landraces with modern landraces. Approach: The molecular markers RAPD and ISSR were used as an efficient tools to estimate the intra-and inter-cultivar polymorphism among six barley KSA landraces collected from different … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 12 Mar 2012 · 7,505 accessesView PDFCite
Research ArticleOpen accessIn the abstractPlasma Beams Free Vibration Ivestigation using the Boubaker Polynomials Expansion SchemeK. BoubakerProblem statement: In the present study, plasma beams free vibration frequencies alteration has been investigated through an original protocol. Approach: The Boubaker Polynomials Expansion scheme BPES has been performed for deducing and ranging the dimensionless frequencies of the beam vibrations. Results: Natural frequencies of the plasma beam have been estimated for given parameters values. Conclusion: Yielded results have been compared … …Physics International, Vol. 2, Issue 2 · 25 Jan 2012 · 7,992 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrevalence Study of Coxiella burnetii in Aborted Ovine and Caprine Fetuses by Evaluation of Nested and Real-Time PCR AssaysFarhad Safarpoor DehkordiProblem statement: Q fever is a ubiquitous zoonosis caused by Coxiella burnetii, an obligate intracellular rickettsial organism that caused abortion and stillbirth in ruminants. Approach: The prevalence of Coxiella burnetii in Iran is essentially unknown. Its traditional diagnosis is based on culture, serology and conventional PCR. In this present study, for more sensitive and accurate detection and prevalence's determination of … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 4 · 13 Jan 2012 · 9,000 accessesView PDFCite
Research ArticleOpen accessIn the abstractAspergillus Niger Metabolites Efficacies Against the Mosquito Larval (Culex Quinquefasciatus, Anopheles Stephensi and Aedes Aegypti) Population after Column ChromatographyNamita Soni, Soam PrakashProblem statement: Mosquito is a very common vector of several tropical diseases such as malaria, filariasis, dengue and chikungunya. Till todate, many xenobiotics have been used to control mosquito population and protect people from mosquito born diseases but increasing rate of resistance against these xenobiotics is a major concern in the disease control management. In contrast, extensive use of these … …Current Research in Microbiology, Vol. 2, Issue 1 · 21 Dec 2011 · 15,211 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew approach between the Optical Basicity and the Dielectric Constant through the Molar Polarizability for Some Binary GlassesEl-Sayed MoustafaProblem statement: In the present study, a new correlation between the optical basiciry which describes the electronic charge clouds around the oxide glass and the dielectric constant has been proposed through the molar polarizability of the binary oxide glasses. Approach: Two experimental forms have been suggested relating the optical basicity and the molar electronic polarizability. Hence, the dielectric constant and … …Physics International, Vol. 2, Issue 1 · 26 Oct 2011 · 7,769 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenotoxic Profile of Motor Garage WorkersNandan M. Shastri, Hemlata PantProblem statement: One way to study the effects on an exposed population is to conduct monitoring studies, using relevant biological parameters with a short term manifestation, such as cytogenetic analysis express the damages to the DNA or to the chromosomes resulting from exposure can be identified. The present study was thus designed to elucidate the effect motor garage environment on … …American Journal of Infectious Diseases, Vol. 7, Issue 3 · 15 Oct 2011 · 8,005 accessesView PDFCite
