OBJECTIVE To evaluate the effect of an educational campaign for reducing the breeding places of Aedes aegypti, the principal vector of dengue; and to compare its effects with the ones obtained by spraying of malathion at ultralow volume. DESIGN Randomised community trial. SETTING Colima city, in the State of Colima, Mexico. PARTICIPANTS Householders of 187 houses, randomly selected from t...

The detection of structural changes in time series from industrial processes monitoring is of great interest. We investigate the limits and possibilities of two recently developed methods, one for the off-line detection of changed volatilities [Wied et al., 2011] and one for the on-line detection of changes in the course of the time series [Borowski and Fried, 2011]. The investigation is carrie...

In this manuscript, we have developed an efficient spraying method to successfully fabricate a series of flower-like coordination polymers (CP) microparticles, including Co/BDC (1,4-benzenedicarboxylate) metal organic frameworks (MOF) and infinite coordination polymers (ICP) microparticles, as well as Ni-Co/BDC MOF and Zn/DOBDC (2,5-dioxido-1,4-benzenedicarboxylate) MOF. The spraying method has...

Electrospray ion sources efficiently produce gas-phase ions from proteins and their noncovalent complexes. Charge-state distributions of these ions are increasingly used to gauge their conformations in the solution phase. Here we investigate how this correlation is affected by the spraying conditions at the early stage of droplet generation, prior to the ionization process. We followed the fold...

We determined effects of aerial sprays of the insect growth regulator pyriproxyfen on sweetpotato whitefly, Bemisia tabaci (Gennadius) (B biotype), in Arizona cotton (Gossypium spp.) fields. We measured survival for males and females from a susceptible strain and a laboratory-selected resistant strain, as well as for hybrid female progeny from crosses between the strains. Insects were exposed d...

Feline urine spraying inside the home is a common problem behaviour that owners seek advice for from veterinarians. Individual trials relating to a variety of interventions produce variable results, and to date, no consensus on the value of different treatments has emerged. This study therefore aimed to meta-analyse, current data from appropriate published clinical trials that evaluate treatmen...

an experiment was conducted in order to evaluate the effects of humic acid spraying on  grain yield and yield components of wheat, in agricultural research and natural resources center of tehran province, in 2010-11. a split-plot layout within randomized complete block design with three replications were used. main plots were three irrigation treatments contains of normal irrigation, non-irriga...

while weeds in sugar beet farming reduce crop yield and quality, they also lead to higher labor and material losses. in recent years, in order to eliminate or reduce the damage caused by weeds in sugar beet farming, weed control has gained importance. to this end, various studies have been conducted on robotic weed control by detecting weeds using image processing algorithms and hoeing or spray...

to evaluate the effect of zn sulfate foliar application on morphologic and quantitative characteristics of safflower (carthamus tinctorius l.) cultivars, a field experiment carried out in ramin agriculture and natural resources university of khouzestan, iran, in a factorial arrangement in a randomized complete block design with four replications, during 2012-2013. treatments consisted of two sp...
