a suitable diet and oviposition substrate are two basic needs for successful mass rearing of orius spp. and this may reduce their production costs. the effect of various foods containing eggs of ephestia kuehniella and sitotroga cerealella with various pollens were investigated on the biological parameters of o. albidipennis in the laboratory. moreover, survival, hatching rate and fecundity of ...

background aromatic organic solvents are extensively used in various industries. xylene is a colorless, transparent liquid, with the characteristic odor of the aromatic hydrocarbons family, which is widely used in industries. adsorption is a conventional method of purifying polluted air containing volatile organic compounds (vocs). zeolite has many unique properties such as high capacity, molec...

In this study, we evaluated the activity concentration of natural radionuclides (226Ra, 232Th and 40K) for fifteen (15) different brands of tile samples used for building purposes in Nigeria. The tile samples were analyzed using High purity Germanium gamma detector. The mean activity concentrations of 226Ra, 232Th, and 40K were observed to be 61.1 ± 5.5 Bq/kg, 70.2 ± 6.08 Bq/kg and 514.7 ± 59.8...

This study investigated the numbers of large granular lymphocytes (LGL) and their relationship to natural killer (NK) function, as assessed by their capacity to lyse the human tumor target, K562. Peripheral blood mononuclear cells from 42 normal controls and from 171 patients suffering from various nonmalignant or malignant diseases were evaluated. Also studied were samples from a patient under...

Two systemic neonicotinoids, imidacloprid and thiamethoxam, are widely used for residual control of several insect pests in cotton (Gossypium spp.), vegetables, and citrus (Citrus spp.). We evaluated their impact on six species of beneficial arthropods, including four parasitoid species--Aphytis melinus Debach, Gonatocerus ashmeadi Girault, Eretmocerus eremicus Rose & Zolnerowich, and Encarsia ...

INTRODUCTION Honey has a wide range of antimicrobial activity. All previous studies have considered honey's effect on a single microbe. The present study investigated activity of honey towards a high dose of single or polymicrobial culture. MATERIAL AND METHODS 10 µl specimens of Staphylococcus aureus (S. aureus), Streptococcus pyogenes (S. pyogenes), Escherichia coli (E. coli) and Candida al...

Despite the availability of several therapeutic options, a safer and more effective modality is urgently needed for treatment of bladder cancer. Specific immunotherapy is effective, but severe side effects limit its clinical use and underscore the need for unconventional therapies using less toxic substances. Many natural substances are touted for their medicinal aspects and side effect profile...

The effects of 89Sr treatment on the natural host resistance of CD-1 mice and the enhancement of resistance by immunomodulators to infection with Listeria monocytogenes or herpes simplex virus type 2 (HSV-2) were determined. In the CD-1 mouse, single-dose treatment with 89Sr caused a profound decrease in the number of circulating monocytes (Mo), lymphocytes, and polymorphonuclear leukocytes (PM...

Natural ageing process occurs throughout the life cycle of textile products, which may possess influences on the release behavior of additives such as silver nanoparticles (Ag NPs). In this study, we assessed the releasability of Ag NPs from a Ag NPs functionalized textile in five different exposure scenarios (i.e. tap water (TW), pond water (PW), rain water (RW), artificial sweat (AS), and det...

Various intra and extracranial cephalometric horizontal reference planes have been used to formulate diagnosis and plan individualized treatment for an integrated correction of the malocclusion. Aim: The aim of this study was to evaluate variability of intracranial reference planes, i.e sella-nasion, basion-nasion, Frankfurt horizontal, functional occlusal, mandibular and maxillary-mandibular b...
