pulmonary arteriovenous malformations (avms) are rare vascular malformations of the lung that usually led to a notable risk of serious and life-threatening complications. there is considerable debate about the best management of strategies for the group of patients with diffuse avms. several therapeutic options have been reported for management of this abnormality among which coil embolization ...

In this article, an innovative supervision system will be proposed that can observe and analyze health of Circuit Breaker’s trip coil. The proposed design also logs changes in the coil's quality and informs network supervisor in case of Circuit Breaker (CB) failure. This system injects small direct currents to the Circuit Breaker connections and the trip coil to compute CB’s health and characte...

Helical coil heat exchangers are widely used in industrial applications ranging fromcryogenic processes, air-conditioning, and nuclear reactors to waste heat recovery due totheir compact size and high heat transfer coefficient. In this kind of heat exchangers, flowand heat transfer are complicated. This paper reports a numerical investigation of theinfluence of different parameters such as coil...

b a ckground: we aimed to extract the ingredients from leaves of gossypium hirsutum (bt cotton) using different solvents and evaluate for potential use to control different larval stages of mosquito species, aedes aegypti and anoph eles stephensi . m e t hods: qualitative and quantitative estimation of ingredients from go. hirsutum (bt) plant extract was carried out and their inhibitory action ...

background: microsporidia are known to infect a wide variety of animals including mosquitoes (diptera: cu­licidae). in a recent study on the mosquito fauna of chahar mahal and bakhtiari province, at the central western part of iran, a few larvae of anopheles superpictus were infected with a microsporidium-resembled microorganism. cur­rent investigation deals with the identification of the respo...

The World Health Organization (WHO) classifies dengue as a disease important in public health. The epidemiology and ecology of dengue infections are strongly associated with human habits and activities. The present study aimed to evaluate the knowledge and practices regarding dengue infections among rural residents in Samar Province, Philippines. A cross sectional design was adopted for this in...

A randomized, double-blinded, placebo-controlled study was conducted to examine the effect of spatial repellent (SR) in households at risk of malaria in Indonesia. Following presumptive radical cure for malaria in 180 adult men representing sentinels of new infection in four clusters within two villages, all households were given either metofluthrin or placebo mosquito coils. Weekly blood smear...

Botanical metabolites are increasingly realized as potential replacements to chemical insecticides. In the present study, Acacia nilotica seed essential oil and seed pod solvent extracts were tested for bioefficacy against three important types of mosquitoes. Mortality was recorded 24 h post-treatment, while smoke toxicity of adult mosquitoes was recorded at 10 min intervals for 40 min. Seed po...

Vector control is the main means of preventing and controlling some parasitic pathologies (malaria, dengue, chikungunya ...). This strategy is mainly focused on reducing contact between human/ vector. This protection is through the use of insecticide-treated mosquito nets, the wearing of long, clear and covering clothes but by using mosquito repellents such as body products, sprays or coils. Th...
