Research ArticleOpen accessPhrase in the titleConformal Mapping of Temperature Variation in Compost HeapJonah Chukwuemeka Agunwamba, Oji Achuka NwokeLaboratory in vessel trapezoidal compost system was designed and constructed. Temperature variation in the compost heap was measured for five days at various depths. Mathematical model for the variation of temperature of the composting process was developed using Conformal Mapping Technique. One of the parameters in the model had two distinct roots, one a positive root and the other negative … …American Journal of Environmental Sciences, Vol. 12, Issue 3 · 17 Jun 2016 · 7,347 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSeasonal Variation of Soil Resistivity and Soil Temperature in Bayelsa StateJohn Tarilanyo Afa, C. M. AnaeleProblem statement: Due to the climatic variation for the year and it's sever harmattan during the month of December to March with the high keraunic level (80-90) in the areas, it was necessary to know the seasonal variation of soil resistivity. The seasonal variation and the nature of soil have considerable influence on electrical characteristics and therefore affect the earthling … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 8,724 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptimization of Biochar Quality from Palm and Cacao Waste through Variation of Pyrolysis Temperature and Duration as a Soil Amendment MaterialIwan Saputra, Sugeng Prijono et al.Palm and cacao waste are high-quality raw materials for producing quality biochar that enhances soil fertility, provided that the biochar production process takes into account various aspects of pyrolysis. The pyrolysis conditions, such as temperature and duration, significantly impact the quality of the biochar produced as a soil amendment. The type of raw material, pyrolysis temperature, duration, and other conditions … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 27 Jul 2024 · 5,558 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Seasonal Temperature on the Genotypic Variability of Flowering Duration in Pearl Millet (Pennisetum glaucum) in NigerSani Daouda Ousmane, Mouhamadou Mounkaila Boureima, Maman Nassourou Lawali et al.Heat stress is a major contributor to crop losses worldwide. Millet [Pennisetum glaucum (L.) R. Br.] is a staple crop for inhabitants of arid and semi-arid regions of the world, due to its extraordinary adaptation to drought and high temperatures. Climate change points to an overall increase in temperature, the effect of which on crop growth and productivity remains to … …American Journal of Agricultural and Biological Sciences, Vol. 17, Issue 1 · 30 Nov 2022 · 6,125 accessesView PDFCite

Research ArticleOpen accessIn the keywordsEvaluation of Temperature Trend In Contaminated Tidal Flat In The Ariake Sea, JapanM. A. Moqsud, Shigenori Hayashi, y. j. Du, Daisuke suetsuguThermal environment of the tidal flat is one of the major parts of the contaminated geo-environment of the Ariake Sea. The activities of marine ecosystem in tidal flats depend strongly on the thermal environment. In order to get a clear idea about the thermal environment of the tidal flats of the Ariake Sea, two study areas, Iida and Higashiyoka tidal … …American Journal of Environmental Sciences, Vol. 2, Issue 3 · 30 Sep 2006 · 6,744 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBiological Control of Spodoptera frugiperda Eggs Using Telenomus remus Nixon in Maize-Bean-Squash PolycultureAntonio GutiA©rrez-MartAnez, Alfredo Tolon-Becerra, Xavier B. Lastra-BravoThe maize earworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is an important pest in maize. Telenomus remus Nixon (Hymenoptera: Scelionidae) is an important control agent of this pest due to its capacity to invade the whole egg mass. The percentage of parasitism by Telenomus remus Nixon (Hymenoptera: Scelionidae) on Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) eggs was evaluated in maize-bean, … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 3 · 17 Jul 2012 · 10,883 accessesView PDFCite
