there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
In this paper, the effects of periodic partial harvesting of a continuously grown crop on augmentative biological control are analysed. Partial harvesting can remove a proportion of both pests and biological control agents, so its influence on the control efficiency cannot be a priori neglected. An impulsive model consisting of a general predator-prey model in ode is used. It is augmented by a ...
In order to prove the acute stimulatory effects of estrogen on pituitary gonadotropin release, we have performed the present experiments in 8 women with a hypergonadotropic state due to surgical castration or primary ovarian failure. They received gonadotropin releasing hormone (Gn-RH) for 12-21 h at the constant rate of 20 micrograms/h. In 5 of the women, estradiol-17 beta was concomitantly ad...
Liriomyza huidobrensis, L. sativae and trifolii are polyphagous agromyzid leafminers that have recently arrived in Australia, posing a threat to Australian vegetable ornamental crops. Adventive endemic hymenopteran parasitoids of already present Australia should assist the management these invasive species. Neochrysocharis formosa (Hymenoptera: Eulophidae: Entedoninae) is an idiobiont endoparas...
Abstract Whiteflies (Aleyrodidae) cause high economic losses in agricultural systems worldwide. Heavy reliance on insecticide use for whitefly control has led to the resistance development towards nearly all used groups of insecticides. A more sustainable, widely used, and irreplaceable measure protected cropping is biological by augmentative release parasitoids. All commercially available para...
To enhance biological control of insect pests in greenhouses, facilities and procedures for mass production of the parasitoids, Eretmocerus sp., Encarsia formosa, and Trichogramma brassicae, and the predator, Aphidoletes aphidimyza were successfully developed in Hengshui, Hebei province, China. Mass production of the aphelinid wasps was achieved by using different plant varieties and host insec...
The purpose of this paper was to study the effect of therapeutic positioning on the functional use of augmentative communication equipment. Recent literature on therapeutic positioning as it affects muscle tone and functional activities is reviewed. The effect of positioning intervention on rate and accuracy of head-controlled typing on an augmentative communication machine was measured. The ra...
The purpose of this study was to assess the relationship between maternal responsivity and language outcomes after a 24-session language intervention in a sample of 62 toddlers with significant developmental delays and fewer than 10 spoken words. The data for this secondary analysis were taken from a longitudinal study that evaluated language outcomes after augmented or spoken language interven...
