In recent years, coating processes based on the impact of high-velocity solid particles such as cold spraying and aerosol deposition have been developed and attracting much industrial attention. A novel coating process called 'warm spraying' has been developed, in which coatings are formed by the high-velocity impact of solid powder particles heated to appropriate temperatures below the melting...

powdery mildew disease caused quality and quantity losses of sugar beet production. therefore, five spraying treatments and three sugar beet variety were conducted in split plot design with four reapplications during consecutive two years in kermanshah and mashhad regions. in order to control of disease, tridimorph fungicide was used. spraying treatments were in main plot and variety in the sub...

In order to reduce the hygroscopicity of ammonium dinitramide (ADN), four different ADN/nitrocellulose (NC) samples were prepared from acetone solutions using electrostatic spraying, with concentrations 2.5, 5, 7.5, and 10 mg ml−1. The morphology was analyzed by scanning electron microscopy, regular uniform size examined x-ray powder diffraction differential calorimetry investigate crystal stru...

The equilibrium measure of a compact plane set gives the steady state distribution of charges on the conductor. We show that certain moments of this equilibrium measure, when taken about the electrostatic centroid and depending only on the real coordinate, are extremal for an interval centered at the origin. This has consequences for means of zeros of polynomials, and for means of critical poin...

Absorption of the herbicide paraquat (1,1'-dimethyl-4,4'-bipyridinium) by mixer-loaders and spray operators on a Sri Lankan tea plantation was assessed over five consecutive days of spraying. Beginning on the day before spraying started and continuing for each of the five spraying days and for seven days after the last day of spraying, 24-hour urine samples were collected from each of the worke...

Low-pressure cold spraying is a newly developed technology with high application potential. The aim of this study was to investigate potential application of this technique for producing a new type of transparent conductive oxide films target. Cold spraying technique allows the manufacture of target directly on the backing plate; therefore the proposed sputtering target has a form of Sn+In2O3 c...

The effect of exogenous application; seed priming or foliar spraying of salicylic acid (SA) on Yecora Rojo and Paragon wheat cv. under NaCl-salinity. Gas exchange parameters, growth parameters, yield and yield components were reduced in both cultivars under salinity stress with foliar spray and soaking seeds. Exogenous application of SA through foliar spraying or seed soaking showed a slight in...

In order to assess possible human effects associated with glyphosate formulations used in the Colombian aerial spray program for control of illicit crops, a cytogenetic biomonitoring study was carried out in subjects from five Colombian regions, characterized by different exposure to glyphosate and other pesticides. Women of reproductive age (137 persons 15-49 yr old) and their spouses (137 per...

This paper exploits the variation in aerial spraying across time and space in Colombia and employs a panel of individual health records in order to study the causal effects of aerial spraying of herbicides (Glyphosate) on short-term health-related outcomes. Our results show that exposure to the herbicide used in aerial spraying campaigns increases the number of medical consultations related to ...
