با توجه به تولید روزافزون نانو ذرات مغناطیسی و کاربرد مفید آن در سیستم­ های بیولوژی، تاکنون مطالعات کم ­تری در زمینه اثرات جانبی این مواد در بدن موجودات زنده صورت گرفته است. بررسی فاکتورهای خونی و مشخص کردن تابلوی خونی هر جاندار علاوه بر آن­ که به­ عنوان یک شاخص فیزیولوژیک مهم به­ شمار می ­رود، در تشخیص بیماری­ها نیز می­تواند بسیار مفید واقع شود. 200عدد ماهی کپورمعمولی دریای خزر با وزن میانگین ...

In order to study the effects of supplementary irrigation and nano iron oxide on  the grain yield, and  some physiological and biochemical traits of wheat (Triticum aestivum L.) under rain fed conditions, a factorial experiment was conducted based on a  randomized complete block design with three replications in Agricultural Research Station of Ardabil, Northwest of Iran, in 2016. Factors inclu...

One of the fast responding methods of plants to fertilizer application is foliar application, which saves fertilizer consumption too. Foliar application of micronutrients is a useful method, especially when roots are unable to absorb necessary elements from soil. The amount of available iron (Fe) in calcareous soils, with high pH, is low for sensitive plants, such as sorghum, to Fe deficiency. ...

UNLABELLED Iron deficiency is the most common nutritional disorder worldwide with substantial impact on health and economy. Current treatments predominantly rely on soluble iron which adversely affects the gastrointestinal tract. We have developed organic acid-modified Fe(III) oxo-hydroxide nanomaterials, here termed nano Fe(III), as alternative safe iron delivery agents. Nano Fe(III) absorptio...

Silicon is one of the beneficial nutrient elements for the most of the plants. This element improve the growth and yield of plants. The aim of this study was to evaluate the effect of foliar spray and root application of Micro- and Nano-SiO2 on concentration of macro- and micro elements and content of silicon in canopy of strawberry. Strawberry plants in the 4-5 leaves growth stage and two weeks...
