in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
introduction: reuse of wastewater for agricultural irrigation is increasing due to an increased demand for water resources in different parts of the world. almost 70% of deviated water from rivers and pumped groundwater is used for agriculture. if wastewater is used for irrigation in agriculture, then the amount of discharged water from natural sources will be decreased and the flow of wastewat...
Distribution of molluscs in the eastern part of the Persian Gulf were studied during the PG-GOOS cruise (Oct-Nov 2012), using the 250 cm2 Van Veen grab for sampling. Sixty gastropod and 23 bivalve taxa in addition to one scaphopod taxon were identified. Gastropods constituted 80% of molluscs. The abundance of molluscs averaged 1398.36 (±261.95) ind./m2. Costellaria sp. was the most abundant ...
