To identify factors associated with incidence of visceral leishmaniasis (VL), we surveyed 13,416 households in Bihar State, India. VL was associated with socioeconomic status, type of housing, and belonging to the Musahar caste. Annual coverage of indoor residual insecticide spraying was 12%. Increasing such spraying can greatly contribute to VL control.

Due to large line spacing and planting distances, the adoption of continuous uniform pesticide spraying in vegetable farming can lead waste, thus increasing cost environmental pollution. In this paper, by applying deep learning online identification methods, control technology for target-oriented is studied with cabbages as research object. To overcome motion blur low average precision under st...

As a type of novel surface engineering technology, the application cold spraying in manufacturing and remanufacturing high-end precision parts is very suitable. However, disadvantage low interface bonding strength can easily induce coating peeling at coating/substrate under effect applied loads. Therefore, finding suitable nondestructive testing method significant to evaluate cold-sprayed proce...

this experiment was conducted to study the effect of nozzle types and the time of herbicide incorporation in soil on weed control, using split plot design by randomized block design. the main plots were soil and herbicide mixing time and the subplots were nozzle types with three replications. this study was performed in karaj station of seed and plant improvement institute, located 25 km west o...

A vacuum microplasma spray system, operating on gross power levels of 1-3 kW, with powder feed rates below 1 g/min and using plasma gas mixtures of argon and hydrogen, was built and tested. In order to improve the deposition efficiency and quality of coatings, the system was analyzed and the matter of particle entrainment into the plasma jet core was identified as a critical sub-process. Partic...

PURPOSE To assess the effectiveness of a pilot integrated pest management (IPM) program in controlling cockroaches in an apartment complex, without pesticide sprays. METHODS A brief educational session and booklet were provided to tenants. Non-spray pest control methods were promoted. A telephone questionnaire was administered at pre- and post-test to assess knowledge, attitudes and practices...

Introduction The possibility of application of electric probes for diagnostics of thermal plasma jets is limited, especially due to the interaction of the probe with plasma. Nevertheless, some important information can be obtained. Electric probes were used for measurement of plasma potential in arc plasma [Chapman and Jones, 1978; Hrabovský and Konrad, 1991; Popov and Gateval, 2001], and for d...
