In this paper, aluminum coatings were prepared on a steel substrate by thermal spraying, and the corrosion morphology resistance of coating investigated salt spray immersion tests. The results showed that after three months tests, still exhibited surface without significant damage had good tolerance. Further effective protection can be achieved spraying with paint. After test, rate samples thic...

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...

Carbon dots have received much attention due to their unique physicochemical properties and diverse applications in bioimaging, optoelectronic devices, catalysis, agriculture. Here, this work, we report a simple hydrothermal synthesis of nitrogen phosphorus−doped carbon (N, P−CDs). The optical physical the synthesized N, P−CDs are analyzed using systematical spectroscopy electrical characteriza...

Low-pressure cold spraying has gained much significance for its good economy in recent years. However, compared with high-pressure spraying, the unsatisfactory performance of coatings prepared by this method is a key problem restricting further development. To improve properties coating without incorporating severe conditions, paper proposed an original shot-peening-assisted low-pressure cold-s...

This Chagas disease prevention project via housing improvement aims to determine the efficiencyof different interventions in vector control. The following study describes the target communities, disease magnitude, and housing improvements. Transmission levels are analysed from an ecological and socioeconomic perspective. Special interest was focused on the peridomicile as the origin of domicili...
