Research ArticleOpen accessIn the abstractTransversely Cracked Beam's Finite Elements with a Hinged EndM. Skrinar, T. PliberšekTwo new beam finite-elements to be used for the transverse displacement analysis of slender beams with transverse cracks are presented where the derivations are based on a simplified computational model. The beam stiffness matrixes are presented in symbolic forms for beams with a single transverse crack and a hinge at one of the nodes. Since in the derivations the corresponding … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 6,916 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Benthic Fauna in the Discharge Lagoon of a Shrimp Farm With Special Emphasis on the PolychaetesLuis Rafael Martínez Córdova, Luis Fernando Enríquez OcañaA study of benthic fauna, with special emphasis on polychaetes, was made in the discharge lagoon of an experimental shrimp farm and a pond of the farm. The discharge lagoon was divided into three sections and stocked with shrimp at low density (6 Pl/m2). Neither formulated feed nor fertilization was used in these sections. The control pond was stocked with … …OnLine Journal of Biological Sciences, Vol. 7, Issue 1 · 31 Dec 2007 · 6,684 accessesView PDFCite
Research ArticleOpen accessIn the abstractSubacute Toxicity of Crocus Sativus L. (Saffron) Stigma Ethanolic Extract in RatsDaryoush Mohajeri, Ghafour Mousavi, Mehran Mesgari et al.The medicinal properties attributed to Crocus sativus L. (saffron) are extensive. The safety of saffron is important in relation to its medicinal applications. This study was performed to elucidate the possible toxic effects of ethanolic extract of Crocus sativus L. stigma on liver, kidney and some hematological parameters in rats. Wistar rats were randomly assigned into four groups of eight … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 4 · 31 Dec 2007 · 8,565 accessesView PDFCite
Research ArticleOpen accessIn the abstractAmbient Levels of Primary and Secondary Pollutants in a Residential Area: Population Risk and Hazard Index Calculation over a Three Years Study PeriodS. Al-Salem, A. Al-FadhleeThis paper aims at presenting data collected over the period of three years (2004-2006) in a residential area in the state of Kuwait. The data collected include ambient levels of primary and secondary pollutants with a number of metrological parameters. A series of unfiltered and filtered concentration roses were plotted to determine the predominant sources as well as the prevailing … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,463 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Carcass Weight and Muscle on Texture, Structure, Rheological Properties and Myofibre Characteristics of Roe DeerJoanna Żochowska-Kujawska, Kazimierz Lachowicz, Małgorzata Sobczak, Leszek GajowieckiMyofibre characteristic, texture, structure and rheological properties of selected muscles (BF, SM and L) of roe deer of different carcass weight were compared. Muscle texture and rheological properties was determined with the TPA and relaxation test, respectively, performed with a Instron 1140 device. Fibre type percentage and structural elements (muscle fibre cross sectional area and perimysium thickness) were measured in … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,582 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Steam Conditioning and Extrusion Temperature on Some Anti-nutritional Factors of Soyabean (Glycine max) for Pet Food ApplicationsB. Purushotham, P.M. Radhakrishna, B.S. SherigaraExtrusion processing of vegetable ingredients such as soyabean (Glycine max) characteristically depends on associating process conditions that influence the product qualities. The process parameters were optimized for extrusion of steam-conditioned material in order to obtain the maximum nutritive value by inactivating the anti-nutritional factors such as urease, trypsin inhibitors and lipase. The processing conditions such as moisture content, temperature and … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 1 · 31 Jul 2007 · 9,030 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparison Between the New and the Old Versions of Jordan Seismic CodeM.A. MusmarThe study comes as a vital step to shed120 light upon the purport of the recently published version of Jordan Seismic code (JSC), and how the drawbacks of the old version are surpassed. The new JSC code oversteps the old provisions, in that input parameters now have pronounced and significant physical meanings. The study concludes that the conversion from service … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 7,875 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation Techniques for Monitoring and Controlling the Performance of the Computer Communication NetworksIbrahiem M.M. El Emary, Adanan I. Al RabiaThis study was concerned with making a comparative study between four types of time series model with the goal of choosing the optimum one to predict the performance of a computer communication network. The investigated four types of time series are: Least Square (LS), Fourier series, Exponential Weighted Moving Average (EWMA) and the Auto Regressive Integrated Moving Average (ARIMA).

Research ArticleOpen accessIn the abstractDifferent Methods for Pion-nucleus Optical PotentialS. A.E. Khallaf, A. A. IbrahimElastic and inelastic cross-sections for pion scattering on 12C at pion kinetic energy ranging from 50 to 260 MeV are computed using three independent methods of π± -nucleus optical potential, the 3α-particle model of the nucleus, the equivalent local Kisslinger potential and the Laplacian one. Reasonable fits to the measured values are obtained for 12C without adjusting free parameters. The … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,390 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDetermination of Atmospheric Turbidity and its Correlation with Climatologically ParametersU. Ali Rahoma, A. H. HassanStudy of Atmospheric turbidity is important for purposes of meteorology, ecology, climatology and monitoring of atmospheric pollution. Linke Turbidity factor (LT) is commonly used to model the attenuation of solar radiation in the atmosphere. The probable dependence on the water vapor content of the relationship linking LT to Angstrom’s turbidity coefficient B, is discussed. In this study, a procedure for … …American Journal of Environmental Sciences, Vol. 8, Issue 6 · 28 Dec 2012 · 6,987 accessesView PDFCite
