Research ArticleOpen accessIn the keywordsA Computer Aided Diagnosis System for Lung Cancer Detection\Using Support Vector MachineM. Gomathi, P. ThangarajProblem statement: Computer Tomography (CT) has been considered as the most sensitive imaging technique for early detection of lung cancer. Approach: On the other hand, there is a requirement for automated methodology to make use of large amount of data obtained CT images. Computer Aided Diagnosis (CAD) can be used efficiently for early detection of Lung Cancer. Results: The usage … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 8,285 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of N and K Fertilizers on Nutrient Leaching and Groundwater Quality under Mature Oil Palm in Sabah during the Monsoon PeriodPetronella G. Ah Tung, Mohd Kamil Yusoff, Nik Muhamad Majid et al.Problem statement: The oil palms are mainly grown in the humid tropics with high rainfall. Soluble Nitrogen (N) and Potassium (K) fertilizers are commonly required by the oil palm plantations to maximize palm productivity due to the highly weathered soils with low fertility. Thus, leaching losses of N and K nutrients may be unavoidable and these nutrients may move further … …American Journal of Applied Sciences, Vol. 6, Issue 10 · 31 Oct 2009 · 10,143 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInfluence of Heat Treatment in Sintering Process on Characteristics of Al2o3-Zro2 Ceramics SystemsA. Rittidech, T. TunkasiriAl2O3-ZrO2 ceramics containing 5-50 mol% ZrO2 were prepared by solid state reaction method. The bulk density, average grain size and microhardness of Al2O3-ZrO2 ceramics system as function of ZrO2 content were investigated. The dense Al2O3-ZrO2 ceramics were successfully by means of carefully control processing parameters that include sintering temperature and heating/cooling rates. These ceramics with higher ZrO2 content was obtained … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,008 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHigh Rate-Dependent Interaction Diagrams for Reinforced Concrete ColumnsTaher Abu-Lebdeh, Sameer Hamoush, Wonchang Choi, Moayyad Al NasraProblem statement: There is a need to better understand the rate dependence behavior of reinforced concrete structures in order to improve their response to impact and blast loads. Analysis and design of reinforced concrete structures subjected to seismic loadings has been recommended in many FEMA guidelines. However, reevaluation of design becomes extremely important in cases where large deformations are expected … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 27 Jan 2011 · 8,020 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDiagnostic Value of Serum and Cerebrospinal Fluid Procalcitonin in Differentiation Bacterial from Aseptic MeningitisZhinous Bayat Makoo, Hamid Reza Soltani, Akbar Hasani et al.Problem statement: Acute bacterial meningitis is one of the most important causes of medical emergency diseases, which can cause high mortality and morbidity rates. Early antibiotic therapy is life saving in bacterial meningitis. One of the most common etiologies of acute meningitis is viral. Differentiation between bacterial and Aseptic meningitis is mandatory, which leads to avoid useless administration of antibiotics. … …American Journal of Infectious Diseases, Vol. 6, Issue 4 · 31 Dec 2010 · 12,078 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn HIV/AIDS Model with Variable Force of Infection and its Application to the Epidemic in UgandaFlugentius Baryarama, Joseph Y.T. Mugisha, Livingstone S. LuboobiAn HIV/AIDS model is formulated with variable force of infection for the adult population. Its actions are reduced to a prevalence equation that is a non-logistic equation whose explicit solution is derived. The implications of applying the solution to the evolution of the HIV/AIDS epidemic are discussed with respect to the positive boundedness of the coefficients. Prevalence projections are presented … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,964 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInfluence of Different Freezing Curves on the Acrosome Integrity of Male Goat Sperm CellsSofia Alexandra Fagundes Lopes, Henrique José Duarte Rosa, António Chaveiro, Fernando Moreira da SilvaThe aim of the present study was to evaluate the effect of three different freezing curves on male goat’s sperm viability and acrosome integrity. Semen was collected on three adult male goats in February (Azores, Portugal, latitude 38°39′N) using an artificial vagina and a female with induced heat. Three collection sessions were spaced of approximately 5 days. The study followed … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 19 Feb 2021 · 6,616 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Critical Review of Climate Change Induced Psychosocial Impacts and Options for Strengthening Social Support SystemsParnali Dhar Chowdhury, C. Emdad Haque, Graham SmithProblem statement: Climate change and its associated manifestations have only recently emerged as significant threats to health faced by Canadians. The emergence of these threats has meant that Canadians are faced with increasing health-related concerns that are more frequent, more severe and occurring in communities where they have not been previously experienced. The compounding effects of change in weather patterns … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 26 Aug 2011 · 7,425 accessesView PDFCite
Research ArticleOpen accessIn the abstractPostnatal Muscle Growth and Allometry in Anatomical Regions of Russian Black-Pied Heifers and their Crosses With Hereford and Charolais Under Intensive RearingIvan Petrovich Prokhorov, Grigorii Sergeyevich Shekhovtsev, Yulia Vasilevna ShoshinaCrossbreeding dairy cattle with specialized beef breeds is an effective strategy to increase beef production, yet data on muscle growth patterns in crossbred heifers remain limited. This study aimed to evaluate the growth intensity and redistribution of muscle mass in anatomical regions of carcasses in Russian Black-Pied heifers and their crosses with Hereford and Charolais breeds. A scientific experiment was … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 2 · 10 Aug 2026 · 920 accessesView PDFCite
