it is not possible to understand developments of a country’s culture and civilization without knowing his believes and myths. whether it is north or south, east or west, planes or mountains, sahara or deserts, here in iran every corner includes valuable and precious treasures which are known all over the world, and cultural – historical objects which are found here adorn all well known museums...
Amorphous silica from sugarcane bagasse ash (Si-BA) was extracted and used as a support for iron (Fe). The FeSO4 loaded onto the Si-BA by 3 different methods consisting of refluxing (RF), incipient wetness impregnation (IWI) physical mixing (PM) methods. prepared materials glyphosate adsorbents were Fe/Si-BA-RF, Fe/Si-BA-IWI Fe/SI-BA-PM. All further studied several techniques. There X-ray diffr...
Purpose. This study evaluated the P sorption characteristics of soils under smallholding land use in Wolaita Zone, Southern Ethiopia. Methods. Soil samples (0–20 cm) were collected from each home garden, grazing land, cropland, and woodlot three replications at two sites analyzed for isotherm data selected soil properties. Results. The generated by equilibration with solutions fitted Freundlich...
اندازه گیری شدت صدا (sound intensity) برای تشخیص منابع نویز در یک مجموعه متراکم از قطعات در حال کار و مرتبط با یکدیگر در خودرو کابردهای فراوانی دارد. خوشبختانه بر اساس تلاشهای محققان [ j.y.chunf] and [f. j. fahy] سیستمی طراحی شده که میتوان بدون استفاده از اتاقک آکوستیک شدت صوت را با دقت خوبی در محیط های آزاد اندازه گیری کرد.
the purpose of this study was to determine the relationship between blood buffer capacity and aerobic power (vo2max) with ability to perform high intensity intermittent activities in young football players. methods: 27 male football players (age 17.66 ±0.49 years) selected as subjects. blood samples were collected before and after the yoyo intermittent test. then, after 48 hours, the bruce trea...

Environmental sustainability appraisal of adsorption for exclusion the malachite green toxic dye was center attention in this work. The influenced goals were to analyze consequences novel composites fabricated by sodium alginate with guar gum and birm (SA@GG@B composites) ion gelation. This work not only explains feasibility sorbent its application removal stuff but also proclaimed various effe...
A novel hydrothermal zirconium oxide (ZrO2) ion exchange material was successfully synthesized by hydrothermal technique. The material has been characterized using different tools such as thermal analysis (DTA-TGA), FT-IR and X-ray diffraction studies. The results show that the prepared ZrO2 is pure and with a unique shape and it belongs to the hexagonal system. Chemical resistively of the mate...
This article compares the sorption behaviour of 2,4,6-trichlorophenol, 2,3,4,6-tetrachlorophenol, pentachlorophenol, chlorotriazine atrazine, methylthiotriazine ametryn, methoxytriazine atratone, hydroxyatrazine, and didelakylated atrazine in a topsoil and an aquifer sediment before and after removal of sorbent organic matter and in humic acid. Freundlich isotherm coefficients Kf and 1/n and fr...
