Research ArticleOpen accessEvery word in the titlePhosphorus Availability Modulates Bradyrhizobium japonicum’s Impact on Soil Micribial Biomass and Soybean (Glycine max (L.) Merrill) Yield in Lubumbashi Tropical SoilsBen Tshibuyi Kasu-Bandi et al.Tropical soils in sub-Saharan Africa exhibit low fertility, high acidity, and limited Phosphorus (P) availability, a key nutrient for agricultural productivity and the sustainability of cropping systems. This deficiency, exacerbated by the strong fixation of P in acidic soils, not only limits plant growth but also the efficiency of the nitrogen-fixing symbiosis between soybeans (Glycine max (L.) Merrill) and Bradyrhizobium … …American Journal of Agricultural and Biological Sciences, Vol. 21, Issue 1 · 13 May 2026 · 1,980 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFeeding by Logistic Feed (Mash, Silage, Pellet and Wafer) Compared with Conventional Feed on Physiological, Blood Biochemical and Body Weight Gain Recovery in Tropical Sheep Pasca TransportationYuli Retnani, Anuraga Jayanegara, Sazli Tutur Risyahadi et al.The process of transportation of animals from one to another area can lead to stress. Animals tend to reduce feed intake which then affects animal performance, so palatable feed is needed, with high energy content, and can speed up the body weight recovery process. This study aimed to evaluate the effect of logistic feed (mash, silage, pellet, and wafer) compared … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 2 · 25 Jul 2022 · 6,222 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluating Plant Species Suitability for a Substrate-Free Tropical Green RoofBruno R. Silva, André Mantovani, Dulce G. Mantuano et al.Greenroofs reduce building exterior-interior thermal flux and mitigate high internal air temperatures, especially in tropical climates. Tropical greenroofs are given little attention and their use remains restricted to a very low percentage of roofs due to high costs compared to traditional roofs, weight overload (mainly due to the chosen substrate) and potential waterproofing problems. We here present an alternative greenroof … …OnLine Journal of Biological Sciences, Vol. 18, Issue 4 · 11 Oct 2018 · 7,523 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleProposed Soil Quality Index for Rehabilitated Tropical Forest Sites in MalaysiaDaljit Singh Karam, Arifin Abdu, Keeren Sundara Rajoo et al.A proposed soil quality index named Tropical Soil Quality Index 2 (TSQI2) was developed in this study using statistical analysed data of selected properties (physical, chemical and biological) of composite soil samples collected from natural, secondary and rehabilitated forests of Chikus and Tapah Hill Forest Reserves, Perak, Malaysia. Results of soil evaluation using TSQI2 showed higher values for planted forest … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 30 Dec 2016 · 8,154 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDYNAMIC DAYLIGHT AND SOLAR CONTROL IN TROPICAL CLIMATEYaik-Wah LimDaylight is dynamic, thus there is no one common solution for all scenarios. It is more critical in tropical climate where the sky is predominantly intermediate; with inconsistent clouds formations which will influence the presence of direct sunlight and daylight availability. In this study, the potential of dynamic internal shading devices for improving daylighting performances in tropical climate was investigated. … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 29 Apr 2015 · 7,092 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFactors Affecting the Geometry of Silver Nanoparticles Synthesis in Chrysosporium Tropicum and Fusarium OxysporumNamita Soni, Soam PrakashProblem statement: Biosynthesis of nanoparticles using fungal cells is a novel approach to develop biotechnological possess such as bioleaching and bioremediation. In the present study, an effort was made to investigate the effect of physio-chemical parameters on the silver nanoparticle formation with the fungus Chrysosporium tropicum Carmichael and Fusarium oxysporum Schltdl. Approach: The possibilities to manipulating the geometry of silver … …Current Research in Nanotechnology, Vol. 2, Issue 1 · 20 Jan 2012 · 19,454 accessesView PDFCite

Approach: The study is performed by conducting the field visits to cyclone site, collected data and information on damages … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 7,432 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAssessment of Thermal Comfort in Respect to Building Height in a High-Density City in the TropicsAnisha Noori Kakon, Mishima Nobuo, Shoichi Kojima, Taguchi YokoProblem statement: The significance of urban design and planning in the tropics lies mostly on its climatic and regional concerns. Among many design parameters, building height is an important parameter which affects thermal climate in the city considerably. This study investigated the effect of building height on outdoor thermal comfort during the daytime in summer in Dhaka, Bangladesh which is … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 3 · 30 Sep 2010 · 8,755 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Converting Secondary Tropical Peat Swamp Forest into Oil Palm Plantation on Selected Peat Soil Physical PropertiesMohd Suffian Firdaus, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: The conversion of forest land into oil palm plantation is considered to be one of the causes of soil degradation and loss of tropical land forest in Southeast Asia. The objective of this study was to compare selected peat soil physical properties of secondary tropical peat swamp forest and oil palm plantation to determine the effect of forest … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 8,742 accessesView PDFCite
