were undertaken. In one area it was over 90 per cent, but since the introduction of these measures the spleen rate has been much reduced with a fall in the incidence of malaria and blackwater fever. Due to the war, difficulty in obtaining oil for spraying is being experienced, and the spleen rate is rising. During the past 12 years, I have seen 33 cases of blackwater fever in my practice in the...

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...

Deployment of a suspension feedstock has been known to alleviate problems associated with using sub-micron and nanosized powder for thermal spraying monolithic as well powder-suspension ‘hybrid’ composite coatings. However, hybrid never previously used in high-velocity air-fuel (HVAF) spraying. In this work, the very first time, chromium carbide (Cr3C2) co-sprayed along an Inconel-625 (IN-625) ...

Thermal barrier coatings are essential to protect the combustion chamber liner material from harsh environments in modern gas turbines that used aerospace and land-based power generation facilities. As there several different materials produce thermal coatings, conventional coating is yttria stabilized zirconia (YSZ). The most common method manufacture YSZ plasma spraying due its flexibility ra...

Thermally sprayed ceramic coatings are applied for the protection of surfaces that exposed mainly to wear, high temperatures, and corrosion. In recent years, great interest has been garnered by spray processes with submicrometric nanometric feedstock materials, due refinement structure improved coating properties. This paper compares microstructure tribological properties alumina using conventi...

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 ...

ABSTRACT Advances in Nuclear Magnetic Resonance (NMR) spectroscopy is a cornerstone structure elucidation of polycyclic 'cage' scaffolds. Due to the compactness these compounds, much overlap, as well unique through-space and bond NMR interactions are frequently observed. This review serves guide for future derivatives by providing some typical relevant aspects characteristic trends, substituent...
