the increased surface area-to-volume ratio of nanoparticles, quantum size effects and the ability to tune surface properties through molecular modification make nanostructures ideal for environmental remediation. the present piece of work reports the preparation and characterization of nano cellulosic fibers (ncfs) with further polymeric reinforcement using vinyl sulphonic acid for the remediat...
the effects of trichloroacetic acid/methylene chloride (tcac/mc) on the mechanical properties and solvent texturing of polyester yarns are studied. the treatments are carried out in unstrained and strained states at different concentrations of tcac for various treatment times. breaking load and elongation-at-break of treated yarns have been recorded. treatments of polyester yarns with tcac/mc i...
Considering the high water requirement of grass during growth stages and the limitation of irrigation sources, it is important to find a suitable way to reduce the water requirement of the lawns as cover plants used in the Landscape. The purpose of this study was to investigate the effect of 2,4,5-T on the induction of callus from the hypocotyl explant in Kentucky bluegrass, induce in vitro dro...

Chia seeds are rich source of omega-3 fatty acids (a-linoleic acid), proteins, soluble and insoluble fibers, vitamins, minerals and natural antioxidants. Objective: Study of growth, development, yield and oil quality of white and black Chia seeds in different planting dates. Methods: In order to st...
Experiments were conducted to study the effects of temperature and chemical treatments on the vase life of cut Asiatic hybrid lily cultivar Pisa, with sixteen chemical treatments using factorial design with 3 replication arrangements. Lilium cut flowers were harvested when the first flower colored fully. Following chemical treatments, they were grouped in different combinations before storage...
The soybean (Glycine max l. merr) is one of oil seed plants from leguminous family. In this study, the effect of gamma radiation on chlorophyll, soluble and insoluble carbohydrate and composition oil seeds were investigated in soybean. Soybean variety J.K was irradiated with 0,100,200 and 300 gamma ray. The treatment and control seeds planed in with four replicates. The highest amount of total ...
this study was conducted to investigate the effects of age and sex on the fleece characteristics of 40 iranian indigenous khorasan goats. goats were divided into two different sex and age (kids and adults) groups. fiber characteristics under study were: fleece weight, fiber length, lock length, fiber diameter, coefficient of fiber diameter, breaking load, resistance, elongation, hair percentage...
In order to investigate the effects of humic acid and salicylic acid on quantitative and qualitative properties and nutrients concentrations in leaves of cotton var. Khordad, a two-year field experiment were conducted at the Tehran Agricultural and Natural Resources Research and education Center during 2018with randomized complete block design as factorial with two factors as follow: soil ap...
