Research ArticleOpen accessIn the abstractCommunity Participation in Watershed Management ProgramsReza Bagherian, A. S. Bahaman, A. S. Asnarulkhadi, Shamsuddin AhmadProblem statement: Several studies in other countries had shown the influence of socio demographic, knowledge, satisfaction and attitudinal factors in level of community participation in development programs. The question here is, whether these factors would also be effective on community participation in WMP in Iran? Objective: Determine the factors which are influence community participation in order to enhance their participation … …Journal of Social Sciences, Vol. 5, Issue 3 · 30 Sep 2009 · 8,937 accessesView PDFCite
Research ArticleOpen accessIn the abstractMapping QTLs Linked to Physio-Morphological and Plant Production Traits under Drought Stress in Rice (Oryza sativa L.) in the Target EnvironmentS. Michael Gomez, S. Satheesh Kumar, P. Jeyaprakash et al.Drought stress is a major constraint for rice (Oryza sativa L.) production and yield stability in rainfed ecosystems. Identifying genomic regions (QTLs) contributing in drought resistance will help to develop rice cultivars suitable for water-limiting environments through marker-assisted breeding. QTLs linked to physio-morphological and plant production traits under drought stress in the field were mapped by evaluating 177 F6 recombinant … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 14,471 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssociation of Landscape Metrics to Surface Water Biology in the Savannah River BasinMaliha S. Nash, Deborah J. Chaloud, Susan E. FransonSurface water quality for the Savannah River basin was assessed using water biology and landscape metrics. Two multivariate analyses, partial least square and canonical correlation, were used to describe how the structural variation in landscape metrics may affect surface water biology and to define the key landscape variable(s) that contribute the most to variation in surface water quality. The results … …Journal of Mathematics and Statistics, Vol. 1, Issue 1 · 31 Mar 2005 · 6,292 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermodynamic Analysis of a Marine Refrigeration Machine with AmmoniaMawhoub Soubih, Samir Zahaf, Dahmane Mouloud, Benkhettab MohamedThe purpose of this study is to present a thermodynamic modeling of a marine chiller using ammonia as a refrigerant. The modeling is based on the first and second laws of thermodynamics and the fundamental laws of heat transfer. System performance in terms of coefficient of performance, total exergy losses and exegetic efficiency, have calculated the temperatures of sea water … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 4 · 25 Nov 2021 · 6,326 accessesView PDFCite
Research ArticleOpen accessIn the abstractEarly Detection and Classification Approach for Plant Diseases based on MultiScale Image DecompositionAssia Ennouni, Noura Ouled Sihamman, My Abdelouahed Sabri, Abdellah AarabThis paper presents a new and powerful approach for detecting and classifying leaf diseases for plant diagnosis with high accuracy. The main contribution of this paper is that a hybrid approach is proposed by using the combination of Partial Differential Equations (PDE) based image decomposition, segmentation, feature extraction, features selection and classification aiming to improve the classification accuracy and provide … …Journal of Computer Science, Vol. 17, Issue 3 · 25 Mar 2021 · 7,205 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Weathering Layer Characteristics over OPL-135 in the Western Part of the Niger Delta Basin, South-South, NigeriaOkechukwu Frank Adizua, Adekunle Oyemade Sofolabo, Olomu Ivory Obi-EgbediAn up-hole seismic refraction survey was carried out in OPL-135 in the Western part of the Niger Delta Basin, (SS) Nigeria. A total of thirty seven (37) up-hole locations in a (4.0×3.750) km grid configuration were drilled and logged over the prospect. The focal objective for the study was to assess the weathering layer characteristics over the prospect, specifically, to … …Current Research in Geoscience, Vol. 11, Issue 1 · 3 Feb 2021 · 11,449 accessesView PDFCite
Research ArticleOpen accessIn the abstractEcophysiology of Chirostoma Jordani Pisces: Atherinopsidae. Habitat Characterization and Population Dynamics in a Periurban Lake (Xochimilco, México)Latournerié-Cervera José Román, Rangel-Nambo María Isabel, Alma Rosa Estrada-OrtegaChirostoma Jordani is an endemic species of the Mexican plateau, whose population, due to anthropogenic causes, has experienced a notable decrease from 2000 to the present, putting its permanence in its natural habitat at risk. Therefore, the objectives of this research were focused on evaluating the population dynamics of C. Jordani through its size and weight distributions and growth rate … …American Journal of Agricultural and Biological Sciences, Vol. 16, Issue 1 · 23 Jan 2021 · 7,546 accessesView PDFCite
Research ArticleOpen accessIn the abstractHaemato-Biochemical Indices of Red Sokoto Goats Fed Various Levels of Earthworm Meal-Based DietsMoshood Adewale Belewu, Ling Shing Wong et al.Blood is essential to life and it is vital for the transportation of oxygen from the lungs to every cell of the body for metabolism purposes. Hence, blood samples were collected from thirty (30) healthy Red Sokoto goats fed an earthworm meal-based diet with ten goats per treatment constituting a replicate in a Completely Randomized design model to evaluate the … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 3 Dec 2024 · 4,963 accessesView PDFCite
Research ArticleOpen accessIn the abstractGroundwater Quality Assessment of Three Zonal Regions in the Sunyani MunicipalityKwabena Antwi Kusi, Samuel Wiafe, Patrick Akaribila NsoniniThis project aimed at assessing the variation of ground water quality (physical, chemical and bacteriological parameters) in relation to the WHO standards from fifteen (15) randomly selected ground water sources in three (3) zones namely Abesim, Baakoniaba/Berlin-Top and New-Dormaa in the Sunyani Municipality. Groundwater samples were collected from five sampling points in each zone to determine the quality of the … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 1 · 11 Jan 2020 · 7,311 accessesView PDFCite
Research ArticleOpen accessIn the abstractRate Effect on Pullout Behavior of Steel Fibers Embedded in Very-High Strength ConcreteTaher Abu-Lebdeh, Sameer Hamoush, Brian ZornigProblem statement: Rate dependence of the newly developed Very-High-Strength-Concrete (VHSC) composites has received little or no attention so far. Approach: In this research, the bond-slip mechanisms of four types of steel fibers embedded in VHSC matrices were investigated through single-fiber pullout tests with the loading rates and matrix strengths are the primary variables. This study presented the experimental results of … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,438 accessesView PDFCite
