The semiarid is characterized by extreme heat, which affects agricultural production limiting the soil's ability to retain water. objective of this study was investigate influence mulch on soil temperature and moisture in a drip irrigated banana plantation Brazilian region. Six thermocouples three probes were used, with coconut coir as mulch. Daytime nighttime surface temperatures compared for ...

Study of a mature petroleum play in the Western Canada Sedimentary Basin (WCSB) indicates that the spatial distribution of petroleum accumulations exhibits a self-affinity characteristic. This characteristic motivated the examination of a fractal model for a quantitative description of petroleum resource spatial distribution. The proposed approach transforms the spatial information with respect...

The health risk resulting from benzene exposure in petroleum refineries was calculated using data from the scientific literature from various countries throughout the world. The exposure data was collated into four scenarios from petroleum refinery environments and plotted as cumulative probability distributions (CPD) plots. Health risk was evaluated for each scenario using the Hazard Quotient ...

Termites are the most important soil fauna in the Sahelian zone of Africa, intensely interacting with the soil. Both the biotic and abiotic state of the soil affect the termite population and activity. The construction by termites of nests, gallery systems or sheetings from soil or from a mixture of soil and other material within the soil horizons or on the soil surface affect the physical and ...

Petroleum exploration and production is an industry that provides researchers with multi-variant challenging “real world” properties. Recently, some petroleum soft computing techniques have gained a greater interest in prediction within the oil industry. This paper is interested in the analysis, classifying, mining and predictions, based on fuzzy as an intelligent system and an intelligent syst...

Urban landscaping conversions can alter decomposition processes and soil respiration, making it difficult to forecast regional CO2 emissions. Here we explore rates of initial mass loss net nitrogen (N) mineralization in natural four common urban land covers (waterwise, waterwise with mulch, shrub, lawn) from sites across seven colleges southern California. We found that N were faster for high-N...

The field experiment was carried out at Forage Block, Instructional Dairy Farm, Nagla, G. B. Pant University of Agriculture & Technology, Pantnagar (Uttarakhand) in spring 2019 to, study the effect mulches and irrigation schedules on productivity water use efficiency sunflower (Helianthus annuus L.) Mollisols Uttarakhand (India). consisted 03 levels i.e., control (no mulch), straw mulch @ 6...

An experiment was conducted in the horticultural farm at Sher-e-Bangla Agricultural University, Dhaka to evaluate Mulch practices on Growth and yield of four Lisianthus germplasm. The consisted treatments (Mo: Control, Ms: Straw mulch, Mc: Cocodust Mbp: Black polythene mulch) germplasms (V1: Arena Type Pure White,V2: Double White, V3: Light Pink, V4:Super Magic Blue), laid out a Randomized Comp...

A method is described for extracting the petroleum from petroleum-bearing ̄uid inclusions hosted in the diagenetic cements of sedimentary rocks, whilst minimising contamination from petroleum in the pore space. A clean-up technique, involving the addition of extraction standards to the rock prior to analysis, has been developed that allows increased con®dence that the hydrocarbons extracted are...

Unexpected price spikes in petroleum can lead to instability in markets and have a negative economic effect on sectors which rely on petroleum consumption. Sudden rises in the price of petroleum do not have to be long-term to cause negative, cascading impacts across the economy. Firms which make futures purchases or hedge against a higher price during a price spike can become insolvent when the...
