to evaluate the competition effect of velvetleaf on cotton, an experiment was conducted in a completelyrandomized block design with split plot arrangement of treatments with three replications at experimentalstation of gorgan university of agricultural sciences and natural resources during 2011 growingseason. the treatments were three row spacing (20, 40 and 80cm) of cotton (as main plot) and f...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
در محیط محاسبات فراگیر، تمام وسیله هایی که قصد برقراری ارتباط با یکدیگر را دارند با رویدادها سر و کار دارند. به همین دلیل، کشف سرویس ها و مدیریت رویدادها در این محیط از حساسیت و پیچیدگی محسوسی برخوردار است. با توجه به اهمیت موضوع، هدف این رساله ارائه ی شیوه ایست که با استفاده از پایگاه داده ی فعال و به کارگیری قوانین eca (event, condition, action)، پیچیدگی رویدادهای بین وسیله ها را کاهش داده ...
بررسی تغییرات کمّی و کیفی اسانس مریم‌گلی اصفهانی (Salvia reuterana Boiss.) در شرایط رویشگاهی و زراعی
Salvia reuterana Boiss. is a herbaceous permanent plant, belongs to the family of Lamiaceae and is the endemic plant of Iran. The aim of this study was to evaluate changes in the essential oil content and composition of this species, appeared in field conditions (Karaj and Abhar) compared with wild condition (Aradan). The aerial parts of the plants were collected at the flowering stage and esse...
objective: this study was planned to investigate whethercoriandrum sativum (c. sativum) is capable of protecting neurons against glucose/serum deprivation (gsd)-induced cytotoxicity. material and methods: the pc12 cells were cultivated for 24 h in standard media (high-glucose dmem containing fetal bovine serum) or for 6 h in gsd condition (glucose-free dmem, without serum) in the absence or pre...
introduction: preferential flow is one of the major processes influencing the rapid movement of pollutants to ground water. macropores created by plant roots provide pathways for rapid transport of pollutants in a soil profile. the growth of plant roots into soil causes creation of big pores that improve water movement and solute transport through soil profile. field soils or undisturbed soils...
In present study, 72 barley double haploid lines with two parents were studied. The experiment was arranged in a completely randomized block design with two replicates under normal and boron stress in hydroponic condition in 2013.The traits Fresh and dry weight of root and shoot, length of root and shoot, length of the largest leaf and the height of whole plant were measured. Statistical a...
Auxin produced by plant growth-promoting bacteria (PGPR) in the wheat rhizosphere, can improve plant yield under water deficit stress condition. To investigate this issue, a completely randomized factorial design with three replications was conducted under greenhouse condition at the University of Maragheh, Eastern-Azarbayjan, Iran during 2019. Treatments were two types of growth-promoting bact...
An invasive shrub, Chinese privet (Ligustrum sinense Lour.), was removed from heavily infested riparian forests in the Georgia Piedmont in 2005 by mulching machine or chainsaw felling. Subsequent herbicide treatment eliminated almost all privet by 2007. Recovery of plant communities, return of Chinese privet, and canopy tree growth were measured on removal plots and heavily invaded control plot...
BACKGROUND: Barley is one of the main important crops in the world, mainly used for animal feed and malt. OBJECTIVES: This study was conducted to evaluate the comparisons of seed yield and its components, phenological and physiological traits of different barley cultivars under Lorestan environmental condition. METHODS: Current rese...
