the present study aimed to investigate the possible effects of focused highlighted error feedback on grammatical accuracy of writing among iranian intermediate efl learners. after selecting 52 homogenous participants from among 70 university students attending azad university of rasht and randomly dividing them into two intact groups of 26 students, the researcher exposed the participants of th...
The green algae Dunaliella salina offers great potential for the food industry due to its high ?-carotene content. To guarantee economic profitability of cultivation, growth conditions must be improved. Therefore, effects pH and salinity on cultivation alga D. were investigated optimized. simplex method was applied find optimum these two parameters maximize biomass cell number salina. found at ...
the purpose of the present study is to find out whether bilinguals of khuzestan-arab origin or monolinguals of iranian origin code-switch during learning or speaking english and which group is more susceptible to code-switch. to this end, the students of 24 classes from high schools and pre- university centers were screened out, and interviewed and their voices and code-switchings were recorded...
because of limitations of production of unicellular green algae (especially in large volumes), this study aimed to culture artemia using three sources of cheap agricultural by-products that were coupled with small amounts of unicellular algae dunaliella salina. the results of growth and survival, biomass production, individual wet weight, wet and ash percent, fcr and sgr and nutritional value o...

BACKGROUND Culture collapse due to high temperatures can significantly impact the profitability of outdoor algal cultivation systems. The objective of this study was to model for the first time the impact of high temperatures on algal activity and viability. RESULTS Viability measurements on Dunaliella salina cultures were based on cytometry with two fluorescent markers (erythrosine and fluor...
*Correspondence: Jason C. Quinn, Department of Mechanical and Aerospace Engineering, Utah State University, 4130 Old Main Hill, Logan, UT 84322-4130, USA e-mail: [email protected] Processing of microalgal biomass to biofuels and other products requires the removal of the culture from a well-controlled growth system to a containment or preprocessing step at non-ideal growth conditions, such as...
A new method to measure intracellular volume in Dunaliella was developed, where lithium ions are used as monitors of the extracellular volume. Li(+) is shown to be impenetrable to the intracellular volume, insignificantly absorbed to the algae, and is rapidly and evenly distributed within the extracellular volume. The method is suggested to be free of several limitations and consistent errors p...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
