Research ArticleOpen accessIn the abstractFinite Element Analysis of Plasticity- Induced Fatigue Crack Closure with Singular ElementR. Rahgozar, H. Saffari, R. TabatabaeiDeveloping a new method is presented to compute crack opening values in planar geometries using the crack surface nodal force distribution under minimum loading as determined from finite element analyses (FEM). In this technique, two-dimensional elastic-perfectly plastic finite element analyses of middle-crack tension (MT) geometry is conducted to study fatigue crack closure and to calculate the crack opening values under … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 6,850 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effects of Growth Hormone Therapy in HIV-infectionDonald P. KotlerThe results of these studies suggested that the growth hormone might play a role in the management of visceral fat accumulation associated with HIV. Analysis of the treatment effect sizes in the published studies show that the effects of various doses of rhGH on trunk fat fit a dose-response characteristic. …American Journal of Infectious Diseases, Vol. 2, Issue 3 · 30 Sep 2006 · 6,258 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMathematical Modeling and Interpretation of PbPc Gas Sensor ArrayNidal F. Shilbayeh, Mahmoud Z. IskandaraniThe voltage/current characteristics and the effect of NO2 gas on the electrical conductivity of a PbPc gas sensor array is investigated. The gas sensor is manufactured using vacuum deposition of gold electrodes on sapphire substrate with the lead-phathalocyanine vacuum sublimed on the top of the gold electrodes. Two versions of the PbPc gas sensor array are investigated. The tested types … …American Journal of Applied Sciences, Vol. 3, Issue 6 · 30 Jun 2006 · 6,789 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEvaluating the Effect of Soil Particle Characterization on Internal Friction AngleArezou Rasti, Hamid Ranjkesh Adarmanabadi, Maria Pineda, Jesse ReinikainenOne of the critical design parameters used in evaluating soil structure is the friction angle, derived from Mohr's Circle failure criterion. The soil friction angle is an engineering parameter estimated in the laboratory to quantify the soil shear strength in geotechnical applications. This paper indicates an experimental study investigating the impact of particle size on different sandy soils shear strength … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 21 Feb 2021 · 8,890 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThe Effect of RSA Exponential Key Growth on the Multi-Core Computational ResourceMohamad A. Mohamed, Ammar Y. Tuama, Mokhairi Makhtar et al.Cryptography has been widely used as a mean to secure message communication. A cryptosystem is made up of a publicly available algorithm and a secretly kept key. The algorithm is responsible for transforming the original message into something unintelligible. The result of losing the key or cracked algorithm can be catastrophic, where all secret communications will be known to adversaries. … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 25 Nov 2016 · 7,827 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPassage Effect on Aging of Human Umbilical Cord Derived Mesenchymal Stem CellDian Mediana, Isabella Kurnia Liem, Jeanne Adiwinata Pawitan, Noviyanti GoeiTo be used in regenerative medicine, cells should be checked for various conditions, including cell aging. This study aimed to learn senescent profile and its relation to cell viability, proliferation and cell size in various passages, which were done in α-MEM-10% PRP medium, until senescence-associated β-galactosidase (SA-β-Gal) positive cells were found. Stem cells were isolated from umbilical cord tissue by … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 31 Jul 2015 · 8,039 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordTHE ADVERSE EFFECT OF STEEL PARTICLE CONTAMINANTS ON FATIGUE LIFE OF GREASE LUBRICATED BALL BEARINGSA. Stathis, Th. Costopoulos, D. Koulocheris, K. RaptisThe rating life of ball bearings is reduced when hard particle contaminants are present in the lubricant. Usually, this life reduction is taken into account in the calculation of modified rating life by using the contamination factor through a general characterization of the lubrication conditions. However, the impact of contaminant’s variables such as size, hardness and concentration level has to … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 14 Jul 2014 · 6,991 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordBed-Load Sediment Profile and Effect of River Bank Erosion on River Cross-SectionMohd Ekhwan Toriman, Frankie Marcus Ata, Mohd Khairul Amri Kamarudin, Mushrifah IdrisThe processes of lateral and riverbank erosion are among the elements of river morphology dynamic resulting from natural processes and human activities. This process has been studied in detail throughout the research for four months starting from 7 October 2009 to 26 January 2010. In this research, technique of erosion pins were applied at five plots selected along the Chini … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 28 Aug 2013 · 7,337 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEffect of Body Weight and Age at Puberty and Mating on Subsequent Gilt Development Weights, Litter Traits, and Colostral Immunoglobulin G of the F1 Large White X Landrace GiltsThembela Happines Matukane, Khathutshelo Agree Nephawe, Bohani Mtileni et al.The purpose of this study was to assess how body weight and age at puberty and mating in F1 Large White x Landrace pigs influence subsequent gilt development weights, litter characteristics, and colostral immunoglobulin G levels. A total of 168 gilts were categorized into different weight groups, i.e., body weight at puberty (lighter gilts: <103 kg, moderate gilts: 103-109 kg) … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 4 · 12 Oct 2024 · 5,956 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordNose Color of Charolais × British Crossbred Beef Steers Alters Body Weight at a Common Degree of Fatness and Marbling Score in Steers Reared Under Similar Management from Birth through FinishingZachary K. SmithThis study evaluated differences in nose color (Black or Pink) on carcass traits and mature body weight in Charolais × British crossbred beef steers. Steers (n = 180; 280±18.2 kg) were weaned and fed for 244 days until harvest. The hypothesis was that steers with black noses had Black Angus dams and that steers with pink noses had Red Angus … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 4 · 7 Oct 2020 · 6,836 accessesView PDF Cite
