nanotechnology has been shown to have promising roles in the development of various industries including the agricultural sector. the primary purpose of this study was to investigate the researchers’ attitude and the obstacle hampering the development of nanotechnology in the agricultural sector of iran. the population of this study consisted of researchers in national research centers/institut...
to study the effects of biofertilizers on physiological and morphological characteristics, as well on essential oil content in dragonhead (dracocephalum moldavica), an experiment was conducted at tarbiat modares university in 2009. the studied factors were: vermicompost (0, 15, 30% v/pot), azotobacter (inoculated and non-inoculated), and phosphatic biofertilizer (inoculated and non-inoculated)....
In this paper, the main goal is to present an experimental comparison of the two prevailing contact modeling approaches of the bipedal locomotion, i. e. rigid versus compliant contact model. To do this, first, an explicit dynamics model for the robot multibody with rigid model of contact for various phases of walking is developed. Then, in order to develop a model with compliant contact, a phys...
As demand for fresh groundwater in the worldwide is increasing, delineation of groundwater spring potential zones become an increasingly important tool for implementing a successful groundwater determination, protection, and management programs. Therefore, the objective of current study is to evaluate the capability of three machine learning models such as boosted regression tree (BRT), classif...
The present research was conducted with the purpose of assessing the interaction between some soil properties and runoff generation time in the downstream of Educational and Research Forest Watershed of Tarbiat Modares University (Kojoor Watershed) located at Southeastern of Nowshahr. Rainfall simulation was done through applying a pumping rain simulator generating rain intensity of some 1.6 mm...
Water deficit, ultraviolet radiation and CO2 concentration enhancement are three environmental stresses that affect nutrition of human in future. This research was conducted in the Research Greenhouse of Faculty of Agriculture, Tarbiat Modares University in 2006, in order to study leaf qualitative traits of durum wheat under different levels of carbon dioxide (400 and 900 ppm), ultraviolet radi...
The aim of this study was to examine the role of university administrators in the development of faculty members in state run universities of Tehran. Research design was a descriptive and survey study. The statistical population were all of faculty members )3389 people (of Tehran Universities (Tehran, Shahid Beheshti, Tarbiat Modares and Al-Zahra), from them, 229 subjects were selected based on...
Energy consumption is very high in greenhouses mainly due to off-season production. The main source of its energy supply is fossil fuels. Due to the disadvantages of fossil fuels consumption and preventive laws in the incoming years, study on reducing consumption and replacing a part of them with renewable energy is essential. In this research, a solar heating system, equipped with a concentrat...
In order to study the morphological characteristics and yield of leafy corn hybrids, and comparie them with those of commercial hybrids, an experiment was conducted in the research field of Agricultural College, Tarbiat Modares University in 2005. A complete block design was used with three replications. Hybrids were obtained from crosses between leafy inbred lines and also commercial inbred li...
