Background and Objectives: Antibiotics are one of the important sources of environmental pollution in recent years and are harmful for human health and environment. Therefore, the purpose of this research was investigating removal of penicillin G from aquatic solution by activated canola. Materials and methods: This study was an experimental-laboratory research and performed at batch system....
An experiment was conducted to deter mine apparent total tract digestibility (ATTD) and standardized total tract digestibility (STTD) by grow ing pigs of P in canola meal, 00rapeseed meal, and 00rapeseed expellers. Canola meal and 00rapeseed meal are the coproducts produced after the residual oil has been solvent extracted from the prepressed canola seeds and 00rapeseeds, respectively, wh...
in order to study crop rotation, chemical control and their interactions on weeds density of wheat fields, an experiment was conducted in a split plot arrangement in randomized complete block design with three replications in gorgan agricultural research station for five years. in this study, 10 rotational crops: canola, fababean, barley, white pea, soybean, cotton, maize, sorghum, millet and w...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
there are two major theories of measurement in psychometrics: classical test theory (ctt) and item-response theory (irt). despite its widespread and long use, ctt has a number of shortcomings, which make it problematic to be used for practical and theoretical purposes. irt tries to solve these shortcomings, and provide better and more dependable answers. one of the applications of irt is the as...
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...

Present study investigated the effects of dietary increasing levels of solventextracted canola meal (CM) as a substitute for soybean meal as an energy and amino acid source in finishing pigs. A total of 192 finishing pigs (Landrace × Yorkshire × Duroc; initial body weight of 48.62 ± 3 kg) were randomly allotted to 4 treatments on the basis of BW. There were 4 replicate pens in each treatment wi...
Canola cultivation at high latitudes is becoming more promising in terms of modern climate change. Sustainable crop production requires an understanding yield-limiting factors, which need to be adjusted agricultural management first. Therefore, our study was aimed examining the effect and soil fertility factors on canola yield from 2012 2015 northwestern Russia. Simultaneously, effectiveness ch...
Cover crops can improve soil health by maintaining organic carbon (SOC) and nitrogen (N) contents, yet their dynamics in relation to crop yield a semi-arid cropping system are poorly understood. The main objective of this study was evaluate the response diverse winter cover species mixture on SOC N fractions relationship with sorghum (Sorghum bicolor L. Moench) wheat (Triticum aestivum L.)–sorg...
