in order to determine the effects of applied phosphate bio-fertilizer on yield and morphological traits of wheat, a research was conducted in sari agricultural sciences and natural resources university during 2008-2010. a factorial experiment was performed based on randomized complete block design with four replications. the first factor consists of two levels of phosphate bio-fertilizer (0 and...
abstract in the present research solution of chalcopyrite in sulfuric acid in hydrometallurgy method using electrochemistry with cyclic voltammetry technique has been investigated. the value of maximum reduction peak current of copper ions represents the measure of solubility. in this research different parameters temperature, potential, potential exert time, chalcopyrite concentration, sulfur...
The programs of managing waste materials in developing countries are often unsatisfactory and the unreasonable disposal of waste is a major issue in the worldwide. The main aim of the current study is to: Assess the applicability of Rumex crispus L. in removing heavy metals from the contaminated wastewater effluent form Pharmaceutical laboratories by bio-adsorption method. The dried R. crispus ...
Background: Basil (Ocimum basilicum L.), a member of the Lamiaceae family, has traditionally been used as a medicinal plant in the treatment of headaches, coughs, diarrhea, constipation, warts, worms, and kidney malfunctions. Objective: To investigate the foliar application effects of bio-stimulators and bio-fertilizers on morphological and phytochemical traits of basil (Ocimum basilicum L.). ...
meningitis is one of the most common infectious cerebral nervous system (cns), defined as an inflammation of the meninges. it is clinically categorized into a chronic and acute based on the acuity of symptoms. vomiting, bulging fontanel and fever are the main symptoms in the patients with meningitis. bacterial meningitis is a severe, potentially life-threatening infection that is associated wit...
The polyphagous tomato fruit borer Helicoverpa armigera (Hubner) causes yield loss of 40 – 60 per cent under favourable conditions in Tomato. farmers rely upon chemical insecticides for its management and injudicious use leads to unwarranted problems. bio pesticides as a component integrated pest is one the important factor overcome related issue. Among bio-pesticides entomopathogenic fungi pro...
Introduction: Using bio-indicators, like birds' feathers can represent bio-transference of pollutants in the environment components better. This study was conducted to study and interpolate heavy metal pollution in laughing dove’s feather as a bio-indicator. Method: The heavy metals of Lead and Cadmium were studied in both western and eastern zones of Yazd by feather of laughing dove (Sp...
Background and aims: bio-aerosols in indoor air of hospital wards are significant harmful factor for human health and play important role on nosocomial infections. Therefore, diversity and concentration of fungal bio-aerosols in indoor air of Imam Khomeini and Alavi hospital have been investigated in this study. Methods: This cross-sectional study was conducted in 2 educational hospitals of ...

 Acid mine drainage is mining waste that contains a lot of sulfate and heavy metals such as Fe Mn which can cause environmental damage pollute the ecosystem, therefore it needs to be managed. One way manage acid with phytoremediation techniques using Purun tikus (Eleocharis dulcis). The ability accumulate known by calculating bio-concentration factor (BCF) tranclocation (TF). This study a...
