In this research, tunability of a commercial diode laser has extended to about more than ± 11 nm using a V-shaped external-cavity fabricated around the laser. Although under normal condition it can be tuned up to about ± 4 nm just by changing its temperature and injection current. Such modified diode laser has then used in a difference-frequency generation (DFG) experimental setup as pump sourc...
Aliquots (25 pl ) were derivatized with phenylisothiocyanatc, vacuum dried and dissolved in 100 pl of 5 mwphosphatc buffer, p H 7.4, containing 5% (v/v) acetonitrile. Ten microlitres was applied to a Pico-Tag column (1 5 cm x 3.9 cm) maintained at 38°C. T h e column eluent was monitored at 254 nm. Two eluents A [70 mM-sodium acetate at pH 6.4 containing 6 % (v/v) acetonitrile] and B [60% (v/v) ...
BACKGROUND Abdominal visceral obesity has been reported to be associated with cardiovascular risks than body mass index, waist circumference, and abdominal subcutaneous fat. On the other hand, there is evidence that subcutaneous fat has a beneficial role against cardio-metabolic risks such as diabetes or dyslipidemia. However, little is known regarding the association between high visceral fat ...
In this study, the growth of sixty-one bacterial strains in crude oil were determined spectrophotometrically at 620 nm. Pseudomonas aeruginosa G1, Pseudomonas fluorescens G6, Pseudomonas stutzeri G11 and Pseudomonas putida G15 were chosen for the study based on the efficiency of crude oil utilisation. At 1% (v/v) crude oil concentration, P. stutzeri G11 strain degraded a maximum of 69%. The per...
دراین پایان نامه دوروش جدید اندازه گیری اسپکتروفتومتری غیرمستقیم آرسنیک(v) با استفاده از سیستم - cpc/i3ارائه شده است. بخش اول شامل اندازه گیری غیر مستقیم مقادیر اندک آرسنیک به کمک سورفکتنت ستیل پریدینیوم کلرید در محیط آبی است. اساس روش بر مبنای کاهش آرسنیک (v) بوسیله یون یدید در محیط اسیدی و تشکیل بعدی یون تری یدیدمی باشد. یون تری یدید می تواندبا ستیل پریدینیوم کلرید برای تشکیل کمپلکس تجمع یونی...
Voltage-gated K(+) (K(V)) channels are implicated in detrusor smooth muscle (DSM) function. However, little is known about the functional role of the heterotetrameric K(V) channels in DSM. In this report, we provide molecular, electrophysiological, and functional evidence for the presence of K(V)2.1 and electrically silent K(V) channel subunits in guinea pig DSM. Stromatoxin-1 (ScTx1), a select...
