رنگ های نساجی یکی از منابع مهم آلودگی محیط زیست هستند. بیش از 50 درصد رنگ مصرفی، در فرایندهای مختلف رنگرزی وارد فاضلاب شده که علاوه بر تغییر رنگ آب، باعث جلوگیری از نفوذ نور به درون آب و اختلال در عمل فتوسنتز شده که منجر به تخریب اکوسیستم آبی و برخی گونه های آبزیان می شود. در سال های اخیر با تولید و استفاده فراوان رنگ های سنتزی که نسبت به رنگ های طبیعی ساختار پیچیده تری داشته و از نظر شیمیایی ب...
BACKGROUND Here we set out to standardize long-lasting, visually-attractive devices for Glossina swynnertoni, a vector of both human and animal trypanosomiasis in open savannah in Tanzania and Kenya, and in neighbouring conservation areas used by pastoralists. The goal was to determine the most practical device/material that would induce the strongest landing response in G. swynnertoni for use ...
The spinal cord injury (SCI) is a detrimental neurological disease involving the primary mechanical injury and secondary inflammatory damage. Curtailing the detrimental neuroinflammation would be beneficial for spinal cord function recovery. Microglia reside in the spinal cord and actively participate in the onset, progression and perhaps resolution of post-SCI neuroinflammation. In the current...
Blue light-emitting diodes (LEDs) in liquid crystal displays emit high levels of blue light, exposure to which is harmful to the retina. Here, we investigated the protective effects of colored lenses in blue LED light-induced damage to 661W photoreceptor-derived cells. We used eight kinds of colored lenses and one lens that reflects blue light. Moreover, we evaluated the relationship between th...
Aims: Currently, the blue light of resin curing unit is frequently used in dental treatment. However, the influence of the blue light irradiation on oral tissue is not clear. The aim of this study was to elucidate the effect of dental blue light irradiation on vascular smooth muscle. Methods: Isolated rat descending aorta was suspended in a superfusion chamber and superfused continuously with K...
The presence of synthetic dyes in textile wastewater is a problematic issue for environmentalist. Nowadays, dye removal is practiced via different methods. Among all these methods, biodecolorization is an ideal technique. The present research apples vermicompost microflora to remove reactive black- C, pH = 7, and under anaerobic condition. At 36h, removal efficiencies of 94.79%, 94.06%, and 93....
One of the most environmentally friendly methods to treat wastewater, especially synthetic dyes, is production activated carbon from agricultural waste. Tamarind seeds were transformed negative-value waste into in order study removal dyes. The particular agro was soaked ZnCl2 for chemical activation increase its surface area and enhance porosity. Physical tamarind done by carbonization process ...

به کارگیری نانوذرات آهن با ظرفیت صفر، یک گزینه برای تصفیه آلاینده های سمی و خطرناک و پاک سازی محل های آلوده است که به سرعت مقبولیت بیشتری پیدا می کند. در این پروژه نانوذرات آهن صفر ابتدا به روش احیاء توسط بورهیدریدسدیم و نیز توسط روش جدید الکتروشیمیایی با استفاده از ولتامتری چرخه ای تهیه شدند. خصوصیات نانوذرات سنتز شده توسط آنالیزهای tem، sem و xrd مطالعه شدند. اندازه میانگین کریستالی نانوذرات ...
