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...
Contact dermatitis is an inflammatory skin disease due to contact with different substances and caused by two mechanisms: Allergy and irritation. Contact dermatitis is a common skin disease and the most common occupational dermatosis. Differentiating between allergic and irritant contact dermatitis is essential in the identification of etiologic factor(s) and hence, its control and prognosis. T...
the effect of a distributed patch mass on the natural frequency of vibration of a laminated rectangular plate with simply supported boundaries is investigated. the third order displacement field of a composite laminated rectangular plate is defined using the two variable refined plate theory. equations of motion of the plate are obtained with the help of calculus of variation. parametric study ...
BACKGROUND Although many malaria control programmes in sub-Saharan Africa use indoor residual spraying with long-lasting insecticidal nets (LLINs), the two studies assessing the benefit of the combination of these two interventions gave conflicting results. We aimed to assess whether the addition of indoor residual spraying to LLINs provided a significantly different level of protection against...
a new multiple c- slotted microstrip patch antenna is proposed. a patch antenna is a wide-beam narrowband antenna. microstrip patch antenna consist of a very thin metallic strip (patch) placed a small fraction of a wavelength above a ground plane. the patch can be designed in any possible shape and normally made by conducting material copper or gold. this paper presents design of a c- slotted ...
BACKGROUND AND AIM: We sought to carry out a systematic review and meta-analysis of the diagnostic value of epicutaneous patch testing in patients with oral lichenoid lesions (OLLs). METHODS: Bibliographic searches were conducted in electronic databases such as PubMed, the Cochrane library, EBSCO, Scopus, Web of knowledge and Google scholar from January 1990 to December 2011. Search terms re...
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...
Spraying techniques have been undergoing continuous evolution in recent decades. This paper presents part of the research work carried out in Spain in the field of sensors for characterizing vineyard canopies and monitoring spray drift in order to improve vineyard spraying and make it more sustainable. Some methods and geostatistical procedures for mapping vineyard parameters are proposed, and ...
