Research ArticleOpen accessEvery word in the titleEffects of 50 HZ Magnetic Field on Some Factors of Immune System in the Male Guinea PigsH. Sedghi, S. Zare, H. Hayatgeibi et al.This study investigated the bio-effects of 50 Hz MF exposure on some Immunological factors (ACTH, cortisol and glucose levels) in male Guinea pigs. The capacity of 50 Hz Electromagnetic Fields (EMF) to interfere in the weakness of endocrine system has been a relevant fact into the scientific community, since we are more susceptible for this kind of exposure, in modern … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 7,997 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Return-Stroke of Lightning Current, Source of Electromagnetic Fields (Study, Analysis and Modelling)Dib Djalel, Haddouche Ali, Chemam FayçalIn this study we present and analysis of the return-stroke lightning current and described their models which existing in the literature by several authors for the evaluation of radiated electromagnetic fields and modelling the coupling with electrical systems based on the calculation of induced voltages. The objective of this work is to take part in the improvement of the coordination … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 30 Apr 2007 · 7,546 accessesView PDFCite
Research NotesOpen accessEvery word in the titleResearch Ethics and Overseas Fieldwork: Are Ethics Committees Oblivious of Cultural Differences?Jones Adu-GyamfiResearch ethics committees have come under increasing criticisms either for been toothless or too fierce. This has mainly come about as a result of the gap in theoretical expectations of research ethics and the experienced realities during fieldwork. In particular, ethics committees incur the displeasure of international students who undertake studies in their own sociocultural contexts. This paper presents a … …Journal of Social Sciences, Vol. 14, Issue 1 · 16 Mar 2018 · 7,551 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNamed Entity Recognition for Kannada using Gazetteers list with Conditional Random FieldsK. P. Pallavi, L. Sobha, M. M. RamyaNamed Entities (NEs) that exist in the sentences are essential to build Natural Language Processing (NLP) applications for Information Extraction (IE) from large corpora. However, generating a large corpus is challenging for resource poor languages, such as Kannada. Further, there is no annotated corpus available online. The challenges faced in annotating NEs with pre-defined classes are: It is morphologically joined … …Journal of Computer Science, Vol. 14, Issue 5 · 24 Feb 2018 · 8,275 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNew Approach of Electromagnetic Fields of the Lightning DischargeDib Djalel, Mordjaoui Mourad, Hocine LabarDespite the significant developments in the protection means of electrical and electronic systems against the lightning and its effects. With its unpredictability and aggress if character, the lightning is the most dangerous phenomenon for electrical systems, which requires more interest and greater effort by researchers and designers means of protection. We present in this study a new analytic model of … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 4 · 18 Jan 2014 · 6,912 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLaboratory Investigation of the Biology of Bactericera tremblayi Wag. (Homoptera: Triozidae) a New Pest in Onion Fields of IranMohammad Hossein. Kazemi, Mohammad Mashhadi JafarlooProblem statement: Psyllids as a small group of insects with plant feeding adult and nymphal stages, not only could have direct feeding damages but they could also transmit plant diseases especially viruses. Bactericera tremblayi had recently increased to high densities in onion fields in East Azarbaijan province in Iran and the pest had become widespread. This was the first study … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 7,501 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleSpartan-3AN Field Programmable Gate Arrays Truncated Multipliers Delay StudyMohammed H. Al MijalliProblem statement: The image processing applications, such as MPEG video compression used in CT scan frames requires real time conditions and the algorithms should be verified and optimized before implementation which cannot be done with Application Specific Integrated Circuits (ASICs) because they are not reconfigurable and cost is very high. Approach: The FPGA is a viable technology that could be … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 6,428 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOn a Class of Nonhomogeneous Fields in Hilbert SpaceRaéd HatamlehTwo-parametric semigroups of operators in Hilbert space with bounded infinitesimal doubly commuting operators are studied. The characteristics describing deviation of a semigroup from unitary one, when infinitesimal operators are unitary, in particular, nonunitary index, have been introduced. Necessary and sufficient conditions for nonunitary index finiteness have been obtained. …Journal of Mathematics and Statistics, Vol. 3, Issue 4 · 31 Dec 2007 · 6,682 accessesView PDFCite
