castor bean, peanut, soy bean and safflower protein isolates were prepared. the amino acid content of each of the protein isolates was analysed and the essential amino acid contents were compared with the fao human requirements. the results indicated that castor bean has the highest oil and the protein content of defatted meal. safflower 3148 (marand, iran) has the highest amount of essential a...

during past few years, the cupressus arizonica has been abundantly planted in tehran, causing a significant increase of allergic diseases from the middle of winter to the beginning of spring. the aim of this study was the comparison of pollen protein content in two major varieties of c. arizonica planted in tehran, including c. arizonica var. arizonica and c. arizonica var. glabra , in order to...

phytoremediation is an eco-friendly method for removal of pollutants, which can be relied upon as a sustainable technology, if implemented under optimum conditions of plant growth. the effectiveness of water hyacinth, a topical weed, for the removal of zinc (zn) and chromium (cr) ions from aqueous solutions has been presented in this article. the potential of this plant in removing metals by ph...

chrysanthemum cut flower is not sensitive to ethylene and its vase life depends on vascular blockage. in order to evaluating of effect of antibiotics and essential oils on the vase life and quality characteristics of chrysanthemum cut flower an experiment carried out based on a rcd with 10 treatments: artemisia at 3 levels (10, 30 and 50 %), amoxicillin at 3 levels (100, 200 and 300 mg l-1), ri...

Reducing dietary protein content in fish feeds will reduce cost of production if growth performance can be maintained. In this study, we assessed the effects of reduced dietary protein content from 33.5% to 27.4% with ideal amino acids profile on the growth, immune parameters, intestinal microvilli length and total ammonia nitrogen discharge of tilapia. After 8 weeks of feeding, growth performa...
