A distributed dynamic model was built using gPROMS 2.3.7 language for an integrated Process including a cogeneration system, a plate heat exchangers set and a salt recrystallization process. It was analyzed the effect of a simulated spray system model on the integrated process, by comparing the global performance of the system with and without sprays. Due to air drift issues, quasi-random time ...

Retention of agricultural sprays on plant surfaces is an important challenge. Bouncing of sprayed pesticide droplets from leaves is a major source of soil and groundwater pollution and pesticide overuse. Here we report a method to increase droplet deposition through in-situ formation of hydrophilic surface defects that can arrest droplets during impact. Defects are created by simultaneously spr...

Liquid ethanol (C(2)H(5)OH) was used to generate a spray of sub-micron droplets. Sprays with different nozzle geometries have been tested and characterised using Mie scattering to find scaling properties and to generate droplets with different diameters within the spray. Nozzles having throat diameters of 470 μm and 560 μm showed generation of ethanol spray with droplet diameters of (180 ± 10) ...

A field study was conducted to explore the suitability of 5 pesticide deposition samplers for airborne spray and ground deposits from ultra-low-volume (ULV) space sprays. Samplers included horizontally stretched stationary cotton ribbons at 2 heights, rotating ribbon, rotating Teflon slides, and filter paper. Slides were also used for droplet-size analysis. A set of 7 samplers of each type was ...

The purpose of this study was to alleviate the harmful effects water restriction, by applying foliar doses putrescine (0, 50, 100 and 150 mg L-1) on basil plants, as well as, understand different soil levels (60% 80% capacity) plant development. We evaluated physiology metabolic pathways plants. Basil plants under restriction reduced their growth dry matter accumulation, leaf status, physiologi...
