nanotechnology is a general term which is related with field of all advanced science term that generally predicates with all modern technologies which consider nanoscales. improvement in the quality of products by adding some nanoparticles and study of their behavior in the presence of these nanoparticles have been obtained in many researches. on the other hand numerous demands for sowing ...
The iron fertilization experiment LOHAFEX was conducted in a cold-core eddy in the Southern Atlantic Ocean during austral summer. Within a few days after fertilization, a phytoplankton bloom developed dominated by nano- and picoplankton groups. Unlike previously reported for other iron fertilization experiments, a diatom bloom was prevented by iron and silicate co-limitation. We used 18S rRNA g...
BACKGROUND Iron supplementation is a chief component in prenatal care, with the aim of preventing anemia; however, extreme maternal iron status may adversely affect the birth outcome. Given the negative consequences of high maternal iron concentrations on pregnancy outcomes, it seems that iron supplementation in women with high hemoglobin (Hb) should be limited. OBJECTIVES The aim of this stu...
Plant nutrition has a vital role in crop production. This study was performed to investigate the effects of different application methods some nutrients (nano Fe, Zn, and Ti), gibberellin on yield, morphophysiological grain protein white beans 2018 as factorial experiment randomized complete block design with four replications. Experimental factors included seed priming (hydropriming, priming, ...
Abstract Background and Objectives: Women of reproductive age are at risk of Iron deficiency. Some Studies reported That There is a relationship between Body indices and iron. Iron overload is also harmful. It enhances the risk of cardiovascular disease which is due to increased Lipid peroxidation. The aim of this study was to investigate the relationship between obesity and iron status in wome...
silicon has useful effects on growth and yield of many plants. the aim of the present study is to investigate the impact of nano silicon oxide on proliferation and improvement of some growth traits of apple, cultivar gala. thus, an experiment was designed based on completely randomized design (crd) with five levels of nano silicon oxide concentrations (0, 25, 50, 100 & 200 ppm) in five replicat...
the aim of this study was to investigate the iron concentrations in serum and carotid plaque in patients with different morphology of carotid atherosclerotic plaque and compared with other metal ions. carotid endarterectomy due to the significant atherosclerotic stenosis was performed in 91 patients. control group consisted of 27 patients, without carotid atherosclerosis. atherosclerotic pla...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
This paper discuss about a novel technique of developing a nano-structured polypyrrole biosensor for measurement of very low concentrations of hydrogen peroxide in liquid media. The proposed fabrication method is very effective in growing a nano-structured conducting polymer layer on a planar conducting substrate. In addition enzyme loading was done under a high electric field of 1000V/m. The d...
