Research ArticleOpen accessIn the abstractAn Investigation of Compressed Natural Gas Engine for Nitrogen Oxides ReductionP. M. Diaz, B. Durga PrasadProblem statement: This study describes the use of Reformer Gas (RG) to alter NOx emission in a CNG-fueled HCCI engine. Comparison with diesel, natural gas has a very high octane number (≈120) and high auto-ignition temperature (≈600°C). Composed mostly of methane, natural gas is the only common fuel to manifest relatively pure, single-stage combustion. Other fuels have stronger low-temperature reaction … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 15 May 2012 · 7,299 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNew Optical Splitter Design for Application in Fibre-to-the Home Passive Optical Network using Virtual Lab PlatformMohd Syuhaimi Ab-Rahman, Ainon Najahah Abdul Aziz, Aimi Amalin Khairuddin et al.Problem statement: In this study, authors present a new design of optical splitter to be applied in FTTH-PON named Multi Ratio Optical Splitter (MROS). MROS was introduced to enhance the power distribution in the optical network. Approach: We also bring in new approach for designing a new optical device that enable us to characterize and analyze the design from waveguide … …Journal of Computer Science, Vol. 8, Issue 6 · 16 Mar 2012 · 7,057 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPerformance Analysis of Multi Spectral Band Image Compression using Discrete Wavelet TransformR. Kousalyadevi, S. S. RamakrishnanProblem statement: Efficient and effective utilization of transmission bandwidth and storage capacity have been a core area of research for remote sensing images. Hence image compression is required for multi-band satellite imagery. In addition, image quality is also an important factor after compression and reconstruction. Approach: In this investigation, the discrete wavelet transform is used to compress the Landsat5 agriculture … …Journal of Computer Science, Vol. 8, Issue 5 · 6 Mar 2012 · 7,043 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA New Modified Gaussian Mixture Model for Color-Texture SegmentationM. Sujaritha, S. AnnaduraiProblem statement: This study presents a new, simple and efficient modified Gaussian mixture model based clustering algorithm for color-texture segmentation. The proposed mixture model introduces a new component density function which incorporates spatial information and the weighting factor for neighborhood effect is fully adaptive to the image content. Approach: It enhances the smoothness towards piecewise-homogeneous segmentation and reduces the edge-blurring … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,332 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHypolipidemic Effects of Coenzyme Q10 in Experimentally Induced Hypercholesterolemic Model in Female RatsAtef M. Al-AttarProblem statement: Hyperlipidemia is well known to play a main role in the development of atherosclerosis. It is characterized by abnormally elevated cholesterol, triglyceride, low density lipoprotein cholesterol and very low density lipoprotein cholesterol levels in the blood. It has been recognized for many years that hypercholesterolemia is a major risk factor for cardiovascular diseases such as atherosclerosis, myocardial infraction, … …American Journal of Pharmacology and Toxicology, Vol. 5, Issue 1 · 31 Mar 2010 · 45,651 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Review: Microbiological, Physicochemical and Health Impact of High Level of Biogenic Amines in Fish SauceMuhammad Zukhrufuz Zaman, A. S. Abdulamir, Fatimah Abu Bakar et al.Problem statement: Biogenic amines are basic nitrogenous compounds present in a wide variety of foods and beverages. Their formations were mainly due to the amino acids decarboxylase activity of certain microorganisms. Excessive intake of biogenic amines could induce many undesirable physiological effects determined by their psychoactive and vasoactive action. Fish sauce which is considered as a good source of dietary … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 8,920 accessesView PDF Cite

Research ArticleOpen accessIn the abstractApplication of Geo-Information Technology in the Study of Soil and Nutrients Loss by Water Erosion for three Different Land CoverMushtak T. Jabbar, C. A.I. Chong-Fa, Wang Tian-Wei, Shi Zhi-HuaThis research integrated the Revised Universal Soil Loss Equation (RUSLE) and the soil statistical analysis with RS and GIS techniques to quantify soil and nutrient loss risk. The Letianxi watershed, located in the southwest part of Hubei Province of China was taken as a case. A system was established for rating soil erodibility, slope length/gradient, rainfall erosivity and conservation practices. … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,792 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSeasonal Variations in Semen Quality of Pasundan Bulls in their Native Tropical EnvironmentNurul Isnaini, Tri Harsi, Anggit Damaratri Lapoliwa et al.The success of artificial insemination highly depends on the semen quality, in which it may significantly associate with the environmental factor. However, the information regarding the seasonal effects on semen quality of Pasundan bulls is still scarce. This study aimed to examine seasonal variation in semen quality of Pasundan bulls in their native environment.
