The Raman response function and Raman nonlinear index of phosphosilicate fibers are calculated for several P2O5 concentrations. The nonlinear index of phosphosilicate fiber is estimated by using the Boling formula, and it is used to calculate the Raman fraction of the nonlinear index. On the other hand, the Raman response function of the phosphosilicate fibers is fitted to a superposition of si...

backgrounds and aims: stroke incidence rate has increased during the past 2 decades. the question of whether calcium, chloride, potassium, sodium levels are associated with stroke has remained controversial. the present study aimed to evaluate the serum levels of potassium, sodium, calcium, and chloride within stroke patients. materials and methods: the study participants consisted of 53 cconse...

The removal of potentially harmful radioactive waste from the anthroposphere will require disposal in geological repositories, designs which often favour inclusion a clay backfill or engineered barrier around waste. Bentonite is proposed as this and understanding its long-term performance behaviour vital establishing safety case for usage. There are many different compositions bentonite that ex...

to investigate the influence of salinity and calcium (ca) on some properties of plantago ovata, a pot factorialexperiment based on randomized complete block design with three replicates was conducted in jiroft, south of kermanprovince, iran. three salinity levels of 0, 100 and 200 mm nacl and ca levels of 0, 5 and 10 mm calcium nitrate wereapplied as the first and second factors, respectively. ...

calcium fluoride deposit during fluoride application. uptake and retention of fluoride by saliva depends generally on the concentration of calcium. in this study, the effect of calcium pre-rinse on salivary fluoride concentration after a 900 ppm fluoride mouthwash was investigated.this cross-over double-blind randomized clinical trial was conducted in a girls' dormitory in zahedan university of...
