Current methods to estimate exposure of wildlife to pesticides from diet depend on a database of published residue concentrations on crop plants normalized to a standard application rate to obtain a residue from a unit dosage (RUD). This database, first published in the early 1970s, was updated in the 1990s. For each category of crops, maximum and mean residues are determined and used to extrap...

Micrografting can be used to produce healthy seedlings, assess scion-rootstock compatibility and promote precocity. The first objective of this project was to study the impacts of in vitro micropropagation of four major Iranian pistachio cultivars, namely ‘Ahmad Aghaei’, ‘Akbari’, ‘Badami Sefid’ and ‘Kalle Ghochi’ in two different medium Murashige and Skoog (MS) and Driver and Kuniyuki...

in this study impact of climate change on operation of gorgan rud basin's dams was evaluated. in this regard temperature and precipitation of the basin for 2011-2035 periods were downscaled using sdsm model and cgcm3-a2 outputs. results showed that annual temperature would increase 0.05°c and annual precipitation would decrease about 4percent. to predict streamflow of the gorgan rud basin ...

Adaptation and defense responses are the consequences of exposure to drought stress in plants. Salicylic acid (SA) as a natural signaling molecule poses a significant impacts on various aspects of plant growth and development. This study investigates the effects of SA on carotenoids content, lipid peroxidation rate and antioxidant enzymes activities. A pot experiment was conducted using a facto...

Korozji, jako procesu korzystnego termodynamicznie, nie można zatrzymać, ponieważ metale występują naturalnie w postaci rud tlenkowych lub soli metali. Dla gospodarki jest to niestety proces kapitałochłonny i niepożądany, jednak z zastosowaniem odpowiednich strategii działania ograniczyć jego skalę. Niniejszy przegląd literatury, głównie lat 2018–2020, skupia się na powłokach kompozytowych opar...
