zinc has previously been reported to alleviate salinity stress in plants. in this study, we monitored various biomass and chlorophyll fluorescence parameters to determine the optimum zinc sulfate concentration that can be used as foliar spray to alleviate salinity stress in glycine soja. the plants subjected to a series of salinity levels (nacl concentration of 0, 100, 200, and 300 mmol l-1), a...
according to coates’s (2004, as cited in zhang, 2010) definition of "conversational dominance" (p.111), it refers to the phenomenon of a speaker dominating others in interaction. specifically, it means how a speaker makes use of certain strategies to get the floor and maintain the floor. thus, the amount of talk is the main measurement for the dominance of the conversation. whether a speaker do...

Ïn addition to the significant effect of protein and lack of calory on growth, zinc is also reported as effective factor in growth of milk feeded infants. Ïn this study the effect of zinc sulfate supplement on weight and hieght of the infants referring to the pediatric endocrine disease clinic of Boalo ho...
cutaneous lesions in fishes due to viral, bacterial, parasitic, mechanical and chemical agents are very common, leading to severe infection and high mortality. the aim of this research was to investigate the effect of long term bath of zinc sulfate (15 and 23 ppm), healing of cutaneous lesions caused by surgical incision in carps. in this study, 210 carps were disinfected by 3% salt solution fo...
To study the effect of zinc sulfate rates on response of bread wheat cv. Cahmran to terminal heat stress conditions in Ahvaz, Iran, this experiment was conducted at the research farm of Agricultural and Natural Resources Sciences University of Khuzestan, Iran in two cropping cycles (2015-2016 and 2016-2017). The experimental design was split plot arrangements in randomized complete block design...

in order to investigate the effect of different levels of zinc on some productive parameters of broiler breeder, an experiment was conducted with 300 hens and 40 roosters of ross 308 strain (40 wk old) in 12 week period in completely randomized design with 4 treatments, 5 replicates and 15 hens and 2 roosters in each replicate. treatments consisted of 4 different levels of zinc (80, 110, 140 an...
Zinc electrowinning is performed with the application of a current through insoluble electrodes (Pb-Ag), causing the electrolysis of zinc sulfate, with or without impurities, and zinc deposition on the cathode of aluminum. The impurities can reduce the current efficiency and increase the energy consumption in zinc electrolysis. In this work, the effect of nickel and magnesium on zinc electrodep...
