Research ArticleOpen accessIn the keywordsEffect of Precipitation Fluctuation on Soil Carbon Storage of a Tropical Peat Swamp ForestAnton Eko Satrio, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: It is important to compare the effect of extremely different rainfall conditions on soil carbon storage of lowland tropical peat swamp forest. Therefore, under these natural rainfall gradient, the objectives of this study were to determine whether rainfall affects soil carbon storage of a tropical peat swamp forest and to determine what correlations between variables occurs which stimulate … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 8,603 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Different Ages of a Rehabilitated Forest on Selected Physico-chemical PropertiesRajeswari A.P. Murugayah, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: This research was important because of still lack of information about rehabilitated tropical forest age effect on infiltration rate. The objectives of this study were to determine the influence of age of forest on soil water infiltration rate and to evaluate the influence of forest age on the relationship between water infiltration rate, soil organic matter and soil … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 8,104 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffects of Converting Secondary Forest on Tropical Peat Soil to Oil Palm Plantation on Carbon StorageCh’ng Huck Ywih, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Peat has been identified as one of the major groups of soils found in Malaysia. Sarawak as the largest state in Malaysia has the biggest reserve of peat-land. There are about 1.5 million ha of peat-land in Sarawak, which are relatively under developed. As is the case with any plant, oil palm trees do sequester carbon as they … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 2 · 30 Jun 2009 · 9,039 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDegradability Characteristics of Treated and Untreated Barley Grain Using In situ TechniqueAkbar Taghizadeh, Nemati ZabihollahThis study was carried out to determine of degradability characteristics of untreated barely grain (UBG) and treated barley grain with autoclaving at 120°C, 5´ (TBG1) and 20' (TBG2), treated barley grain at 100°C, 5´ (TBG3) and 20' (TBG4), using in situ technique in Ghizel sheep’s. The sheep fed diet content 40% alfalfa: 60% concentrate containing 2.9 Mcal kg−1 DM and … …American Journal of Animal and Veterinary Sciences, Vol. 3, Issue 2 · 30 Jun 2008 · 8,305 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSoil Formation by Ecological Factors: Critical ReviewSaeed Zeraat Kar, Aydin BerenjianRegolith is the term we give parent material that has been weathered. The regolith consists of weathered bedrock near the surface including the soil layer. In the Iranian soil layer we will find: decayed parent materials, decaying plant material, decaying animal matter (manure) along with vegetation. Results of the present study show us that methods stimulating natural fertility in Iran … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 2 · 2 Apr 2013 · 7,663 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFractional Calculus Theoretical Evolution for Radiation QuantitiesAmin Al-Okour, Sherin A. Sareireh, Abdullah Ajlouni, Abdul-Wali AjlouniProblem statement: Radiation dosimetry features depend on semi-empirical formulas that lack a strong mathematical framework. This is due to the fact that the microscopic radiation interaction with matter includes energy losses that have never been described properly in quantum mechanics, which deals with conserved energy systems. Approach: Using the recent theory of the quantization of nonconservative systems using fractional calculus. … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 2 Feb 2012 · 6,661 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDurian Husk Properties and its Heating Value EquationPatomsok WilaiponProblem statement: Agricultural residue seems to be one of the most promising energy resources for developing countries. Among the other fruits, durian is a popular one for Thai people. Therefore, a large amount of durian husk is left at the shops or factories. This study was aimed to investigate the characteristics and heating value of durian husk and to develop … …American Journal of Applied Sciences, Vol. 8, Issue 9 · 1 Aug 2011 · 7,856 accessesView PDFCite
Research ArticleOpen accessIn the keywordsComparison of Selected Chemical Properties of Peat Swamp Soil Before and After Timber HarvestingMuhamad Ismawi Salimin, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Peat swamp is an important component of the world’s wetlands. Once they are disturbed the tendency for the soil degradation is very high. This study compared selected chemical properties of a peat swamp soil before and after timber harvesting. Approach: Peat soil samples were taken at 0-15 cm depth in 6 plots with 0.1 ha each plot at … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 8,786 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBehavior of Stabilized Peat Soils in Unconfined Compression TestsWong Leong Sing, Roslan Hashim, Faisal Haji AliProblem statement: Deep stabilized peat columns were known to be economical at forming foundations to support highway embankments constructed on deep peat land. However, failure in the formation of the columns with adequate strength was often attributed to unsuitable type and insufficient dosage of binder added to the soil. Organic matter in peat was known to impede the cementing process … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,452 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTrace Metal Mercury Levels in Residential Homes in KuwaitL. AL-Awadi, A. R. Khan, R. Al-KandariKuwait is an oil rich state on the northeastern corner of Arabian Peninsula and has faced the unprecedented man made environmental disaster in early 1991 of igniting over 600 oil wells those continually burnt for a period of over six months. The use of crude and heavy fuel oil in the power generating facilities has aggravated the pollution due to … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 6,827 accessesView PDFCite
