A synthetic blend of chemicals comprising volatiles released by the human body has been shown to be an effective attractant for female Aedes aegypti in olfactometer bioassays with laboratory-reared mosquitoes. We report the laboratory evaluation of Ae. aegypti response to a synthetic blend tested with 4 types of mosquito traps (CDC model 512, CDC model 1012, CFG, and Fay-Prince traps). Aedes ae...

The paper presents the experimental test results reflecting comparative changes in performance efficiency and emissions of exhaust a naturally aspirated, four-stroke, single-cylinder, air-cooled diesel engine due to its transition from neat rapeseed oil biodiesel fuel blends prepared by mixing various proportion (by volume) methyl ester (B) butanol (Bu). lubricity properties biodiesel-n-butanol...

The photodegradation of a 1:1 blend of poly (caprolactone) and poly(vinyl chloride) has been studied by following carbon dioxide emission during UV exposure. Similar measurements were made on poly(caprolactone) and poly(vinyl chloride) homopolymers prepared and irradiated in the same way. It was found that the blend gave lower CO2 emission than either of the two homopolymers, indicating that th...

In this study, the mechanical properties, fatigue life, and endurance limit values were investigated for composite materials containing natural fiber reinforcement (flax, wool), which arranged by 0°/90° Angle orientation a combination of 45°/-45° angle orientation, then wool woven mixed flax unidirectional interfered with jute woven. Binary blends epoxy polyurethane at v various weight percent ...

In this research, we established a modified 45 flammability test for cotton blend material to measure the flammability of nanosilicone softener treated-cotton blend material. The wet pick-up was about 150±10%. b) The specimens were tested in the cross direction and nine specimens were measured. The average percent weight loss of the untreated cotton blend nonwoven is only 0.9%. The percent weig...

OBJECTIVE The present study was carried out to evaluate the toxic effect of blend of some food colors on Swiss albino rats. MATERIALS AND METHODS A blend (1:1:1) of sunset yellow, metanil yellow and tartrazine showed additive effects on serological parameters which indicate that addition of these dye together in food stuff may give rise to more toxic effects than are produced by each dye indi...

Immiscible blends of ethylene?propylene?diene?monomer (EPDM) and polyoxymethylene (POM), when EPDM is the major phase were compatibilized on addition an ionomer, poly(ethylene?co?methacrylic acid). The inclusion ionomer reduced interfacial tension between two phases, such that diameter POM domains significantly to 0.5 2 ?m, typical required toughen ductile polymers. mechanical properties result...

This study explores a binary solvent system composed of biobased Cyrene and its derivative Cygnet 0.0 for application in membrane technology biocatalytic synthesis polyesters. Cygnet-Cyrene blends could represent viable replacements toxic polar aprotic solvents. The use 50 wt % mixture makes practical difference the production flat sheet membranes by nonsolvent-induced phase separation. New pol...

We present an algorithm to predict the linear relaxation spectra for polymers of fully general and arbitrary polydispersity. As is common in tube theory descriptions polymers, we assume that stress affected by both constraint release escape modes, but unlike most existing consider how these two modes affect each other. argue proper description blend requires consideration multiple embedded tube...
