the toxicity of thiamethoxam and pirimicarb on diaeretiella rapae (mc'intosh) as a parasitoid of lipaphis erysimi (kaltenbach), exposed to residues on glass vials, was investigated under laboratory conditions at 23 ± 2 °c, 70 ± 5% rh and 16:8 h (l: d). moreover, in order to find the negative impacts of both insecticides on the efficiency of d. rapae, the functional response of the exposed paras...

This study investigates the market value impacts of IT-enabled supply chain systems using event study method. The authors examine abnormal stock returns to investments in IT-enabled SCM systems announced by 346 firms from 2001 to 2004, and find significant, positive abnormal returns for two, three, and five day periods surrounding the event date. Further, the authors employ organizational integ...

Horizontal gene transfer (HGT) is known to have contributed to the content of eukaryotic genomes, but the direct effects of HGT on eukaryotic evolution are more obscure because many of the best supported cases involve a new gene replacing a functionally similar homologue. Here, several cases of HGT conferring a plausible adaptive advantage are reviewed to examine emerging trends in such transfe...

Oxidative stress and protein modifications are frequently observed in numerous disease states. Glucose constitutes a vital nutrient necessary to cellular oxygen metabolism. However, hyperglycemia-associated damage is an important factor in diabetes disorders. Albumin, the major circulating protein in blood, can undergo increased glycation in diabetes. From recent studies, it has become evident ...

BACKROUND AND PURPOSE Shoulder apprehension is defined as anxiety and resistance in patients with a history of anterior glenohumeral instability. It remains unclear whether shoulder apprehension is the result of true recurrent instability or a memorized subjective sensation. We tested whether visual presentation of apprehension videos modifies functional brain networks associated with motor res...

BACKGROUND In Canada, national health surveys do not usually include questions pertaining to self-perceived oral health. Those that do use ad hoc sets of questions rather than standardized and validated measures of the functional and psychosocial impacts of oral disorders. AIMS To collect national data on the impacts of oral disorders from a representative sample of Canadian adults and to com...

In Web system development, the non-functional requirements (NFRs) are typically considered only briefly during the requirements elicitation stage and not rigorously articulated by either Web developers or the client. This paper reports on an investigation into this issue involving interviews with Web developers who were engaged in commercial Web development projects. The results from this quali...
