The bed bug, (Cimex lectularius L.), is a difficult pest to control. Prevalence of insecticide resistance among bed bug populations and concerns over human-insecticide exposure has stimulated the development of alternative bed bug control materials. Many essential oil-based pesticides and detergent insecticides targeting bed bugs have been developed in recent years. We evaluated the efficacy of...

The aim of this work was to investigate the effect of oxygen limitation on whole­ cell oxygenases, and to determine how the physiochemical properties of oils affect their ability to enhance the oxygen transfer rate. Whole-cell oxygenase biocatalysts require oxygen as a substrate for the reaction and for the electron transport chain. The productivity of these bioconversions is therefore influenc...

A new method for generating families of ternary spreading sequences is presented. The sequences have aperiodic zero correlation zones and large families are created for a specific sequence length. The sequences are proposed as spreading sequences to provide high capacity and cancel multipath and multiple access interference (MAI) in a single carrier (SC) or multi-carrier (MC) direct-spread code...

Solubility coefficients in blood for benzene, toluene, and xylene were determined as 6.5, 16, and 42 respectively. In lard and olive oil, which were taken to represent human fat, corresponding values were about 450, 1300, and 3900. The coefficient for vinyl chloride in lard and olive oil was 20; the value in blood was too low to be determined by the technique used. Trichloroethylene, used as a ...

OBJECTIVES Aging is an unconscious and gradual process that can lead to changes in biological systems. Induction of oxidative stress and apoptosis, hepatotoxicity and neurotoxicity are involved in the aging process. Regarding the antioxidant property of black seed oil, the aim of this study was to evaluate the anti-aging effect of Nigella sativa (N. sativa) oil on d-galactose-induced aging in m...

A protective digestive microflora helps prevent and reduce broiler infection and colonization by enteropathogens. In the current experiment, broilers fed diets supplemented with probiotics and essential oil (EO) blends were infected with a standard mixed Eimeria spp. to determine effects of performance enhancers on ileal and cecal microbial communities (MCs). Eight treatment groups included fou...

Layered asphalt pavement makes the interlayer contact more complicated. In order to further understand characteristics of interface under vehicle load, this paper analyzes change rule a vertical load condition, based on Goodman model. According pavement, experiment temperature, gradation, amount viscosity-level oil, type and compressive stress are taken as parameters, universal testing machine ...

Marine microorganisms have unique physiological properties and novel metabolites such as biosurfactant to live in extreme habitats (e.g. oil polluted environment). The aim of this study was to characterize some biosurfactant-producing bacteria collected from sediment and seawater samples from the Caspian Sea. These bacteria were isolated using enrichment method in ONR7a medium with crude oil as...

208 The natural food colorants, carotenoids, are of great importance to human health. The scientists at Department of Agricultural, Food and Nutritional Science, University of Alberta, Canada enhanced the efficiency of SC-CO 2 extraction of carotenoids from carrots, by using canola oil as a continuous cosolvent. The carotenoid content of the starting material was determined by traditional solve...

Sesamin, a major lignan in sesame seeds and oil, has been known to lower blood pressure in several types of experimental hypertensive animals. A recent study demonstrated that sesamin metabolites had in vitro radical-scavenging activities. Thus, we determined whether the antioxidative effect of sesamin metabolites modulate the vascular tone and contribute to the in vivo antihypertensive effect ...
