Pesticides are persuasively marketed with the promise that they will 'cure all'; yet there are pressures — including safety concerns — which discourage pesticide dependency. Is a pragmatic middle road the best option?

Spray Modelling in Spray Forming
Multiphase Flow and Heat Transfer in Materials Processing, 1994Abstract In a common point of view, metallurgical spray applications can be devided into the unit operations: atomization / particle injection - particle transport / heat transfer -impingement / compaction. In this contribution, the Eulerian / Lagrangian way of dispersed two-phase flow in sprays with momentum and heat transfer has ...

Spray Drying, Spray Pyrolysis and Spray Freeze Drying
2010In conventional spray pyrolysis (CSP or simply SP), a solution is sprayed into a carrier gas forming small droplets; owing to the high temperature of the surrounding gas, the solvent is vaporized and the solute is precipitated on and within the droplets. If the air temperature is high enough, solute is decomposed to form final solid particles.

VALIDATION OF THE VSB2 SPRAY MODEL AGAINST SPRAY A AND SPRAY H
Atomization and Sprays, 2016The modeling of spray breakup and evaporation is very complex, and several different models have been developed to describe the physical processes involved in these phenomena. However, problems of grid dependence, instability, and tuning issues remain to be adressed.

IEEE Computer Graphics and Applications, 1994
Spray rendering provides a framework for creating and experimenting with different visualization techniques. The name spray rendering is derived from the metaphor of using a virtual spray can to paint data sets. Varying the type of paint in the can highlights data in different ways. Spray rendering is not limited to the paint metaphor, however.

Effects of spray height and spray angle on spray deposition in tobacco plants
2011 6th IEEE Conference on Industrial Electronics and Applications, 2011Due to the decreasing availability of authorized plant protection products, adequate pest control becomes more difficult in tobacco. Although much attention is given to predator-pest interactions in integrated control, almost no research is available about the optimization of spray application techniques in tobacco plants.

Spray Angle and Atomization in Diesel Sprays
SAE Technical Paper Series, 1984<div class="htmlview paragraph">In this investigation, cone angles of high pressure diesel sprays emerging through plain orifices were studied. The study was conducted at constant fuel pressures by using injection system in a single pulse mode.

Spray man and pesticide spraying – A unnoticed story
Archives of Environmental & Occupational HealthPesticide application has become an indispensable process in crop production, but the inappropriate use of synthetic pesticides has led to significant risks for both human health and the environment. When we tried to map the diffusion network of pesticide-related information, we found that spray man is playing a crucial role.
