A pot experiment was executed to investigate the impact of biochar and compost with water-saving irrigation on rice yield, water use efficiency, physicochemical properties soil. Two regimes—namely alternate wetting drying (AWD) continuous flooding (CF)—and four types organic amendments (OA)—namely husk (RHB), oil palm empty fruit bunch (EFBB), a control—were applied evaluate their effects. Under AWD regime, maximum grain produced by RHB (241.12 g), whereas under same amendments, both CF...
Biochar is a potential carbon-rich soil amendment that improves the physicochemical properties of soil, besides acting as controlled release fertilizer. An experiment was conducted to investigate effect biochars on rice yield, fertilizer use efficiency and recovery under water-saving irrigation by 15N isotopic tracer study. Two types alternate wetting drying (AWD) continuous flooding (CF), four biochar treatments such husk (RHB) with urea, oil palm empty fruit bunch (EFBB) urea alone...
Abstract Stable carbon isotope ratio measurements are used to investigate the provenance of vanillin. In this study, a variety commercial vanillin samples and vanilla products were analyzed provide frame reference for variability delta values in various samples, with results ranging from −20.6 −36.7‰ relative Vienna Peedee Belemnite (VPDB). We present information on development two synthetic materials, VANA-1 VANB-1, prepared 0.75 g units glass vials, be calibration other easily combustible...
This study explores the potential effects of alien fishes on native fish community, well-being, and tropic preferences in selected rivers Klang Valley, Malaysia. Following Aquatic Species Invasiveness Screening Kit assessment, most (80%) are invasive. The species occurrences correlated positively (p < 0.05) with poor water quality, such as high ammonia-nitrogen nitrite, but negatively phosphate dissolved oxygen. Anthropogenic characteristics, pollution levels ease accessibility to...
Abstract Aptian to Campanian sediments from the Western offshore Central Orange Basin were studied by integrating molecular geochemistry, inorganic and isotopic studies recognize their geochemical characteristics via reconstruction of basin’s paleoweathering, paleosalinity, paleovegetation, paleoclimate, tectonic records. Molecular analyses both aliphatic aromatic compounds reveal an input dominantly a marine source. The source rocks accumulated in reduced, anoxic, saline water column. Based...
The economic motivation for adulteration and mislabeling of origin is significant as edible bird's nest (EBN) rank amongst the world's most expensive animal products food traditional medicinal uses. aim this study to determine geographical Malaysian Edible Bird's Nest by using bio element fingerprinting techniques carbon, nitrogen sulphur (CNS) isotopes in order avoid product fraud, guarantee quality safety. samples used were authentic processed EBNs from different states Malaysia supplied...
Stingless bee honey's nutritional value is gaining attention, but the impact of harvesting seasons, specifically rainy (September 2018) and dry (February 2019) seasons in Malaysia on honey’s physicochemical properties volatile compounds remains insufficiently explored. This research revealed marginal differences between seasons. However, through individual species cumulative data analysis, honey samples were effectively differentiated based A set seventeen identified as potential chemical...
Upper Cretaceous Gombe Formation coals from Maiganga coalfield, Benue Trough, Nigeria were investigated to evaluate the thermal maturity, organic matter input, paleovegetation, paleoclimatic conditions and depositional environment using bulk molecular geochemical techniques. Vitrinite reflectance Tmax data, maturity biomarker indicators all signify low maturity. Source-related aliphatic aromatic hydrocarbon ratios indicate that are mainly derived terrestrial but with a considerable input of...
