This paper discusses the detection of P V jj1118, 1128 and other broad absorption lines (BALs) in archival Hubble Space Telescope spectra of the low-redshift BAL QSO PG 1254]047. The P V identiÐcation is secured by excellent redshift and proÐle coincidences with the other BALs, such as C IV jj1548, 1550 and Si IV jj1393, 1403, and by photoionization calculations showing that other lines near th...
پروتئازهای قلیایی مهمترین آنزیم های صنعتی محسوب می شوند که در سال های اخیر تحقیقات گوناگونی در زمینه تولید این آنزیم به دلیل کاربرد گسترده آن در صنعت صورت گرفته است.در این پژوهش، پساب صنعتی و ضایعات کشاورزی به عنوان منابع کربن و نیتروژن جهت رشد باکتری باسیلوس سوبتیلیس 1254ptcc برای تولید آنزیم پروتئاز قلیایی استفاده شدند. حداکثر تولید آنزیم u/ml 43/117در محیط حاوی 25% حجمی پساب و g/l 2 تفاله نی...
This paper discusses the detection of P V λλ1118,1128 and other broad absorption lines (BALs) in archival HST spectra of the low-redshift BALQSO, PG 1254+047. The P V identification is secured by excellent redshift and profile coincidences with the other BALs, such as C IV λλ1548,1550 and Si IV λλ1393,1403, and by photoionization calculations showing that other lines near this wavelength, e.g. ...
Perinatal Exposure to Aroclor 1254 Impairs Distortion Product Otoacoustic Emissions (DPOAEs) in Rats
Aroclor 1254 is a widely studied commercial polychlorinated biphenyl (PCB) mixture which, by definition, contains 54% chlorine by weight. Recent reports indicate substantial differences in the congener composition among Aroclor lots and hence their biologic effects. We designed the current study to compare the effects of two lots of Aroclor 1254 (lots 6024 and 124-191). We analyzed these two lo...
A microstructured array of 1254 electrodes on a substrate has been configured to generate an array of local minima of electric field strength with a periodicity of 120μm about 25μm above the substrate. By applying sinusoidally varying potentials to the electrodes, these minima can be made to move smoothly along the array. Polar molecules in low-field seeking quantum states can be trapped in the...
