The role of proper flight line positioning was demonstrated to be critical for maximizing product efficacy when spraying in crosswinds by small-droplet spray strategies. Characterization studies indicated clearly that aircraft height, small drop emission distribution, and the ambient winds combine to dilute the spray cloud before impacting surface targets. A S-fold increase in mortality was ach...

The direct estimation of sea-state bias (SSB) from sea height residuals is extended with a parametric fitting process and a successive smoothing of the remaining residuals. This hybrid method essentially produces a nonparametric SSB model in the form of a smooth grid in a 2dimensional space determined by significant wave height and backscatter coefficient. The hybrid method allows a much higher...

in this study, a laboratory scale continuous plug flow fluidized bed dryer was designed and constructed. a backward-curved centrifugal fan with a 4 kw electromotor was selected based on the maximum pressure drop in the minimum fluidization state and the ability to produce the velocity required for fluidization of the most granular agricultural materials. the fluidization chamber was a rectangul...

A new constant pressure pendant-drop penetration surface balance has been developed combining a pendant-drop surface balance, a rapid-subphase-exchange technique, and a fuzzy logic control algorithm. Beside the determination of insoluble monolayer compression-expansion isotherms, it allows performance of noninvasive kinetic studies of the adsorption of surfactants added to the new subphase onto...

Waste heat recovery is very important, because not only it reduces the expenditure of heat generation, but also it is of high priority in environmental consideration, such as reduction in greenhouse gases. One of the devices is used in waste heat recovery is heat pipe heat exchanger.Anexperimental research has been carried out to investigate the hydrodynamic and thermal performance of a gas...

Air pluviation is a method of preparing laboratory models to carry out many geotechnical experiments. In this study, a new air pluviation device has been developed by the researchers. For laboratory modeling, it is important to calibrate the device using air pluviation to produce accurate specimens with desirable conditions and relative densities. A series of laboratory tests were conducted to ...

The energy of sprinkler irrigation drops splashing on the soil surface or crop canopy depends their size and velocity. kinetic is a major factor degrading surface. effect growing maize drop dissipation water partitioning was analyzed. A field experiment performed solid-set irrigated plot cropped with maize. Measurements were at different locations heights into layout. Tests five heights. At eac...
