tulip is one of the most important flowers to precocity. treatment of tulip bulbs with gibberellic acid reduces the forcing period in the greenhouse resulting energy saving and reduces the tulip’s physiological disorders. this study carried out about three tulip cultivars includes ‘lacourtine’, ‘yokohama’ and ‘red favourite’. the results showed that gibberellic acid reduced significantly stem l...
Due to ever increasing greenhouse cultures, using organic fertilizers for enhancing healthy products is necessary. To investigate the effect of two types of these fertilizers on tomato, in a factorial experiment, based on completely randomized design with 3 replications, with 2 pots in each replication, 0 g/kg humic acid (Humic0) and 1 g/kg (Humic1) and amino acid at 3 levels of 0 g/kg (Amin0),...
Bile salts present in gallbladder of wild and cultured red seabream, Pagrosomus major, a marine teleost were analyzed. The bile from wild red seabream was found to contain two previously unknown bile salts along with two known bile salts, taurocholate and taurochenodeoxycholate. Isolation of each bile salt was performed by column chromatography. Fast atom bombardment mass spectra of the unknown...
زمینه و هدف: رنگها مواد آلی، با ساختار پیچیده، غالبا سمی، سرطانزا، جهش زا، غیرقابل تجزیه بیولوژیکی و پایدار در محیط زیست می باشند و چنانچه بدون تصفیه وارد محیط زیست شوند باعث به خطر انداختن محیط زیست و سلامت انسان می شوند. هدف از این مطالعه سنتز نانو ذره و بررسی کارایی دو فرآیند هیدروژن پراکسید و هیدروژن پراکسید – نانو ذرات آهن صفر ظرفیتی در حذف رنگ Acid Red 18 از محیط های آبی است. مواد و روش...
زمینه و اهداف: رنگ Acid Red 18 یکی از رنگ‌های آزو بوده که در صنایع نساجی و رنگرزی کاربرد دارد. این نوع رنگها غالبا سمی و سرطانزا بوده و برای انسان و محیط زیست ایجاد آلودگی می‌کنند. این مطالعه با هدف بررسی کارایی نانوذرات آلومینا در حذف رنگ Acid Red 18 از محیط‌های آبی انجام شد. روش بررسی: این تحقیق در مقیاس آزمایشگاهی انجام شد و تأثیر غلظت اولیه رنگ (25 تا 100 میلی‌گرم درلیتر)، pH محلول (3، 7و...
Background & Aims of the Study: Organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. The aim of this study was to evaluate the performance of H2O2 and H2O2/Fe0 Iron in removal of dye Acid Red 18 from aque...
Tannic acid presents in varying concentrations in plant foods, and in relatively high concentrations in green teas and red wines. Human ether-à-go-go-related gene (hERG) channels expressed in multiple tissues (e.g. heart, neurons, smooth muscle and cancer cells), and play important roles in modulating cardiac action potential repolarization and tumor cell biology. The present study investigated...
a pot experiment was conducted in a completely randomized design, to study the effect of zinc sulphate (znso4) and ascorbic acid(as) foliar application application 20 and 40 ppm was compared to the control (distillated water) on flowering gazania (gazania rigens l. daybreak red stripe).results were analyzed by spss software and duncan test. results showed that znso4 and as had positive effect o...
