We present simulations of one and two-dimensional infrared (2DIR) and stimulated resonance Raman (SRR) spectra of the dark state (pG) and early red-shifted intermediate (pR) of photoactive yellow protein (PYP). Shifts in the amide I and Glu46 COOH stretching bands distinguish between pG and pR in the IR absorption and 2DIR spectra. The one-dimensional SRR spectra are similar to the spontaneous ...

روش استخراج نقطه ابری به عنوان تکنیک ساده، سریع و ارزان برای حذف رنگهای راکتیو بلو 171 (rb 171) و راکتیو رد 141 (rr 141) به کار گرفته شد. آنالیت بطور کامل در سورفکتانت تریتون x-114استخراج شد. جذب بوسیله اسپکتروفتومتر خوانده شد. طول موج ماکزیمم برای rb171 و rr 141به تر تیب برابر با 595 و 531 نانو متر می باشد. تأثیر شرایط آزمایشگاهی مثل ph، غلظت سورفکتانت، دما و زمان روی cpe مطالعه شدند. درصد جذب...

Results A total of 81.9% (n=104) of the children were registered with triage colour indicating the level of urgency. This was done within a mean of 26.4 minutes from time of arrival. Children younger than 1 year old were significantly more likely not to be triaged compared to children older than 1 year old RR 2.78 (95% CI 1.31-5.93) (p=0.0249). Distribution of triage was; green (lowest level) 5...

Manganese peroxidase (MnP) is the one of the important ligninolytic enzymes produced by lignin-degrading fungi which has the great application value in the field of environmental biotechnology. Searching for new MnP with stronger tolerance to metal ions and organic solvents is important for the maximization of potential of MnP in the biodegradation of recalcitrant xenobiotics. In this study, it...

A survey was conducted at 15 textile plants with dyehouses in western Sweden. Employees with a history of work related rhinitis, asthma, or skin symptoms were offered a clinical and immunological investigation including skin prick tests, skin patch tests, and radioallergosorbent tests (RASTs) to detect specific allergy to reactive dyes. Among the 1142 employees, 162 were exposed to reactive dye...

Abstract Textile effluents being one of the major reasons for water pollution raises concern bodies and habitation surrounding them. The lack biologically safer treatment solutions creates a disposal these effluents. present study focuses on degradation textile dyes using leaf extract Artemisia stelleriana-assisted nanoparticles zinc oxide (ZnO-NPs). ZnO NPs synthesized were confirmed spectrosc...

In previous reports in this series, the formation of organometallic ^-complexes with biologically significant materials (such as vitamin A acetate1, acetylergosterol 2, and esterone 3 have been reported. The objective of this research series is the investigation of the possible occurrence of 7r-complex bonding 4 in biological media. The significance of biological cr-complex bonding has been poi...

We have obtained new CCD BV photometry of the little-studied southern Galactic globular cluster NGC5986, including light curves of 5 of its RR Lyrae variables. The cluster’s red giant branch bump is detected for the first time at V = 16.47 ± 0.03. We derive a reddening and true distance modulus of E(B − V ) = 0.29 ± 0.02 and (m−M)0 = 15.15 ± 0.10, respectively. The cluster’s color-magnitude dia...

Background and Objective: In recent years, wastewater textile treatment is of special importance due to the potential toxicity,cancer activity, and mutagens. The purpose of this study was evaluation of the removal of Remazol Black B (RBB) dyes from aqueous solution by chitosan. Materials and Methods: This laboratory study carried out on synthetic wastewater to assess the effect of factors su...
