BACKGROUND Mosquito strains that exhibit increased tolerance to the chemical class of compounds with a sodium channel modulator mode of action (pyrethroids and pyrethrins) are typically described as "pyrethroid resistant". Resistance to pyrethroids is an increasingly important challenge in the control of mosquito-borne diseases, such as malaria or dengue, because one of the main interventions (...

To investigate the corrosion protection behavior of naturally derived cocoyl sarcosine in combination with N-b-hydroxyethyl oleyl imidazole for steel CR4 0.1 M NaCl, different evaluation systems (weight loss, electrochemical measurements, and spray tests) were used. Both compounds tested concentrations (25–100 mmol/L) variable dip coating times (1–30 min), first individually then combination, t...

The lesser mealworm (LMW, Alphitobius diaperinus (Panzer); Coleoptera: Tenebrionidae) is increasingly used as a novel food and feed source. materials on which this insect species reared may contain residues of insecticides from agricultural use. objective study was to determine whether selected insecticides, spiked the substrate, could bioaccumulate in LMW and/or affect growth or survival. Inse...

ABSTRACT: Degumming and neutralization processes are two essential stages carried out on crude edible oils in order to remove some unwanted impurities namely gums and free fatty acids. In this research study two popular less expensive commercial oils that are consumed to a great extent namely soyabean and sunflower seed oils are selected and subjected to both degumming and neutralization proces...
