Research ArticleOpen accessIn the abstractThe First Report of the Occurrence of Anthracnose Disease Caused by Colletotrichum gloeosporioides (Penz.) Penz. & Sacc. on Dragon Fruit (Hylocereus spp.) in Peninsular MalaysiaMasanto Masyahit, Kamaruzaman Sijam, Yahya Awang, Mohd Ghazali Mohd SatarProblem statement: The increasing of dragon fruit (Hylocereus spp.) plantations in Malaysia enhances the researches on this crop, particularly focusing on its physico-chemical characteristics, great potential health benefits and nutritional value. However, its scientific report of disease is still lacking, primarily on anthracnose disease. This study was then conducted to investigate the distribution of anthracnose disease on dragon fruit and … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 11,824 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMichelson-Morley Experiment another AssessmentKoorosh ShahdaeiProblem statement: Ehrenfest paradox may be the most basic phenomenon in relativity that has a long history marked by controversy, which still gets different interpretations by researches. This assessment is about another paradox in special relativity for observers in none inertial frame that perceiving Galilean transformation. Approach: This assessment reevaluates Michelson and Morley's famous experiment and Lorentz transformation by comparing … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 8,007 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordHeat Transfer and Effectiveness Analysis of a Cross-Flow Heat Exchanger for Potential Energy Recovery Applications in Hot-Humid ClimateA.R.S. Masitah, Mardiana I Ahmad, Y.M. YatimThis paper presents heat transfer and effectiveness analysis based on a physical model of a cross-flow heat exchanger. Using the model, the transferred heat and effectiveness (ε) in terms of temperature and NTU-method are calculated for both hot and cold streams. From the analyses, it is found that as air velocity increases, the transferred heat through heat transfer plates increases. … …Energy Research Journal, Vol. 6, Issue 1 · 15 May 2015 · 13,617 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordStudy of Cutoff Frequency of High Collector Current Density in SiGe Single-Heterojunction Bipolar TransistorG. M. Khanduri, B. S. PanwarThe cutoff frequency performance of an NPN Si/SiGe/SiGe Single-heterojunction bipolar transistor (SiGe SHBT) at high collector current densities has been analyzed using a 2-dimensional MEDICI device simulator. A conventional NPN Si/SiGe/Si Double-heterojunction bipolar transistor (SiGe DHBT) having uniform 14%Ge in the base region has been investigated for comparison. The analysis shows the formation of a retarding potential barrier for minority … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 6,891 accessesView PDF Cite
