in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
In order to assess the effects of different levels of nitrogen (N) and foliar application of iron amino chelate on yield and growth traits of dill medical plant, a factorial experiment was conducted in 2011 using a completely randomized design and three replications. In this experiment, five levels of N (0, 50, 100, 200 and 400 kg/ha N from urea source) and two levels of foliar spray of iron am...
The use of natural products as medicinal agents presumably predates the earliest recorded history. Ocimum sanctum L., is a plant which is used in several traditional medicine systems to cure various diseases. In this study aerial parts of Ocimum sanctum were collected on august 2014 from Shahr-e-Rey in Iran. Fresh and dry partsof plants essential oils were extracted with hydro-distillation and ...
azospirillum is a well-studied genus of plant growth-promoting bacteria. phytohormone production by pgpr is considered as one of the effective factor to increase the tomato yield significantly. in order to study the effect of azospirillum inoculant on on growth characteristics and yields of tomato, three strain of azospirillum were isolated, identified, and purified from tehran suburb soils. to...
this thesis aims at putting together two of the vestest areas of study there is in humanities: bioethics and literature. the two novels in question, oryx and crake and the year of the flood, are considered as some of the most succssful examples of spculative fiction. in these novels the biological and environmental issues raised as looked at from a bioethics point of view.
An experiment was carried out at the Horticulture Farm of the Bangladesh Agricultural University, Mymensingh during the period from November 2010 to January 2011 to study the effects of cowdung and potassium on growth and yield of Kohlrabi. The experiment consisted of three levels of cowdung (0, 20 and 40 t/ha) and four levels of potassium (0, 20, 50, 80 kg /ha). The experiment was laid out in ...
in order to evaluate the impact of different amounts of nitrogen fertilizer on growth and yield of two forage sorghum cultivars, a 2-year field experiment was carried out at the college of agriculture, shiraz university, shiraz, iran during 2010 and 2011 growing seasons. two factorial experiments were carried out in randomized block design with three replicates, in which the treatments included...
Greenhouse experiments in a completely randomized design were carried out to investigate the effects of nitroxin fertilizer (0, 1 and 2 li/ha) on morphological and physiological traits of Amaranthus retroflexus in 2013. The traits in the study included plant height, fresh and dry weight of shoots, roots, stem and leaf, Chlorophyll a, chlorophyll b, total chlorophyll, carotenoids, anthocyanin, a...
The black dot disease of potato is a fungal disease caused by Colletotrichum coccodes (syn. C. atramentarium) that produces accervuli on infected underground plant parts which appear as black dots. The disease appears at the flowering stage and develops up to the season end. The survey on black dot disease of potato in two successive years indicated that the infection percentage is 39.86 in Fer...
BACKGROUND Ensiling may act as a pretreatment of fresh grass biomass and increase the enzymatic conversion of structural carbohydrates to fermentable sugars. However, ensiling does not provide sufficient severity to be a standalone pretreatment method. Here, ensiling of grass is combined with hydrothermal treatment (HTT) with the aim of improving the enzymatic biomass convertibility and decreas...
