ویژگی‌های زیستی به‌ویژه رفتار تخمریزی زنبورهای پارازیتویید یکی از مهم‌ترین عوامل تعیین‌کننده کارایی آنها در مدیریت جمعیت آفت میزبان می‌باشد. این مطالعه الگوی وابسته به سن، نرخ پارازیتیسم، درصد تفریخ و نسبت جنسی زنبور Trichogramma brassicae روی Ephestia kuehniella شرایط آزمایشگاهی (1±25 درجه سلسیوس، رطوبت نسبی %5±70 دوره نوری 16: 8 ساعت (روشنایی: تاریکی)) بررسی شد. نتایج نشان داد T. سنین جوانی (...

An instrument for measuring visual reaction time (VRT) was constructed and later tested on 18 control volunteers. It was established in these subjects that the mean VRT did not vary by more than 6% over a period of 5 days. The equipment was then employed to measure changes in VRT following carotid angiography under general anaesthesia in a series of 48 patients. Of these, 22 patients had no dem...

A structure-guided drug design approach was used to optimize a novel series of aminobenzimidazoles that inhibit the essential ATPase activities of bacterial DNA gyrase and topoisomerase IV and that show potent activities against a variety of bacterial pathogens. Two such compounds, VRT-125853 and VRT-752586, were characterized for their target specificities and preferences in bacteria. In metab...

When the voice register transition (VRT) occurs, vocal-folds motion becomes unstable and the voice pitch jumps abruptly. In this article, we examine the relationship between the fundamental frequency f0 and the first-formant frequency F1 in VRT to reveal the influence of the source–filter interaction (SFI) on VRT. Five Japanese male speakers produced rising glissandos with vowels /a/ and /i/. T...

Auditory reaction time (ART) and visual reaction time (VRT ) between males & females during shift duty in hospital employees have been compared. ART and VRT were studied in 286 hospital employees (141 males and 145 females) during day and night shift duty in the age group of 20 to 60 years. Subjects were presented with two auditory stimuli, i.e. high pitch and low pitch sound and two visual sti...

Variable-rate applications of the nematicide aldicarb were compared to producer standard rates in eight field tests over 3 years. Test areas (308 to 1,015 m long) were divided into eight or five blocks. Each block contained two plots with a variable-rate treatment (VRT) of aldicarb and a producer standard treatment (PST) of aldicarb. Each VRT plot was divided into three subunits and intensively...
