In order to study the impact of drought stress and planting date on safflower yield and yield components, an experiment was performed in Tabriz region in 2011. The experiment was carried out as split-split plot based on randomized complete block design. The main factor which was applied as split plot includes drought stress  with three levels:  (S1) 80 ± 3 mm evaporation from basin level of cla...

Unmodified and gold-modified semiconductor oxides were used for the complete decolorization of non-buffered aqueous safranin O solutions. Photocatalytic properties of commercially available ZnO and TiO2 (anatase nanopowder) were compared with those of gold-modified ZnO (Au/ZnO). Au/ZnO was obtained from commercial ZnO powder through direct current sputter coating. ZnO-ba...

in order to evaluate the effects of different plant densities and nitrogen levels on growth, yield and qualitative characteristics of marigold, a field experiment was conducted as split plot based on randomized complete block design with four replications at the agricultural research station, azad university of torbat-e-jam, during growing season of 2008-2009. main and sub plots were four nitro...

The analysis of tear constituents at point-of-care settings has a potential for early diagnosis of ocular disorders such as dry eye disease, low-cost screening, and surveillance of at-risk subjects. However, current minimally-invasive rapid tear analysis systems for point-of-care settings have been limited to assessment of osmolarity or inflammatory markers and cannot differentiate between dry ...

wheat residues management and modification in tillage time are among suggested practices in weed control. to evaluate the effects of wheat residues and tillage time on weed dry matter and leaf area, corn dry matter and corn grain yield, a study was conducted at darab agriculture and natural resource college, shiraz university during growing season of 2008-2009. this experiment was conducted in ...

Abstract. River sediments falling dry at low water levels are sources of CO2 to the atmosphere. While general relevance emissions from has been acknowledged and some regulatory mechanisms have identified, knowledge on temporal dynamics is still sparse. Using a combination high-frequency measurements two field campaigns we thus aimed identify processes responsible for assess large German river. ...

The objective of the study was to evaluate the effect of the biostimulant Kelpak on true protein and simple sugar contents of Dactylis glomerata and Festulolium braunii at different nitrogen rates. A field experiment was set up as a randomised sub-block design (split-split-plot) with three replicates. The following factors were ha, pure-sown grass species and cultivars (monoculture). Protein co...
