Research ArticleOpen accessIn the abstractInfluence 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 abstractSpeed Estimation of Adaptive Fuzzy-Controlled Piezo-Electric Motor using MLP-Neural NetworkShebel ALSABBAH, Tariq MUGHRABIThe speed of ultrasonic motor of piezo-electric type is usually measured using mechanical sensors such as pulse encoders. However, these sensors are costly and bulky. In this paper, a numerical speed estimation approach of a piezo-electric motor (PEM) is implemented using multilayer perception neural network (MLP-NN). The proposed model evaluates rotational speed and load torque based on the amplitude and … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 6,785 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemoval of Pb+2 Ions from Aqueous Solutions by Adsorption on Kaolinite ClayWaid Omar, Hossam Al-ItawiThe adsorption potential of the kaolinite clay for the removal of lead ions from aqueous solutions was tested. The measured adsorption isotherms at the different temperatures 298.15 K, 308.15 K and 318.15 K were found to be perfectly fit to the Langmuir isotherm equation. A high adsorption capacity was calculated. An increase in the retention capacity with increasing temperature was … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,792 accessesView PDFCite
Research ArticleOpen accessIn the abstractCustom Design of an Analogue Input Digital Output Interface Card for Small Size PLCsMohammad A.K. AliaThis paper describes the design and implementation of an interface card (IC) with analogue input and digital output, designed for use with small size PLCs, which do not support interface features. The absence of generic I/O interface modules due to the differences in PLCs design and software, validates the importance of such work. The IC costs about one third of … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 6,442 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Heat Shock Transcription Factor Family in Entamoeba histolyticaConsuelo G. García, Ma. De la Luz Macias Argüelles, D. Guillermo P Ishiwara et al.The HSTF is a master molecule involved in the transcriptional control of several genes during different types of stress. This transcription factor is a very conserved protein identified in different organisms from bacterial to human. Entamoeba histolytica is the protozoan responsible for the human amoebiasis. This parasite is exposed to different kind of stress as changes in the pH, temperature, … …American Journal of Infectious Diseases, Vol. 3, Issue 2 · 30 Jun 2007 · 7,182 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Evaluation of Aqueous and Freeze Dried Antigen for Sero-diagnosis of VL and PKDL Cases by DATSanjiva Bimal, Shubhankar K. Singh, P. K. Sinha et al.The efficacy of aqueous and freeze dried (FD) antigen was evaluated by direct agglutination test (DAT) for sero-diagnosis of visceral leishmaniasis. A total of 16 samples collected from 5 confirmed Kala-azar (KA) cases, 6 cases 2 each of filariasis, malaria, leprosy and 5 non-endemic healthy subjects were used in determination of cut off titre of both the antigens in DAT. … …American Journal of Immunology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,834 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of the Application of Sewage Sludge and Presence of Pesticides on the Development of the Microbial Population of the Soil and on the Transformation of Organic Carbon and Nutrient ElementsM.E. Sánchez, I. B. Estrada, O. Martínez et al.The laboratory trial consisted in incubating samples of soil and soil treated with sewage sludge, with the application of organophosphate pesticides with different active ingredients under controlled conditions of temperature and moisture. On the basis of a previous study of the influence of the application of sludge on the degradation of pesticides in the soil, a kinetic study is included … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,859 accessesView PDFCite
Research ArticleOpen accessIn the abstractReview of Photochemical Smog Pollution in Jakarta Metropolitan, IndonesiaDollaris R. Suhadi, M. Awang, M. N. Hassan et al.An analysis of photochemical smog pollution in Jakarta was attempted using data from the existing air quality monitoring stations. Ground-level ozone potential is high in Jakarta due to the high traffic emissions of ozone precursors and the favorable surface meteorological conditions. Despite the frequent missing data during the 1996-1999 monitoring, which resulted in lower ozone values, ozone episodes were significantly … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 7,247 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomated Fall Armyworm (Spodoptera frugiperda, J.E. Smith) Pheromone Trap Based on Machine LearningSimon H. Chiwamba, Jackson Phiri, Philip O.Y. Nkunika et al.Maize is the main food crop that meets the nutritional needs of both humans and livestock in the sub-Saharan African region. Maize crop has in the recent past been threatened by the fall armyworm (Spodoptera frugiperda, J.E Smith) which has caused considerable maize yield losses in the region. Controlling this pest requires knowledge on the time, location and extent of … …Journal of Computer Science, Vol. 15, Issue 12 · 19 Dec 2019 · 8,364 accessesView PDFCite
