results certain correlations were found between fundamental frequency in vowel and total vhi, physical, functional and emotional domains of vhi in group 1 (r = 0.636, 0.649, 0.613 and 0.592 respectively). there was good correlation between speaking fundamental frequency and total vhi and its subscales - except the physical subscale - were also correlated. in group 2, the correlations between ji...

Normal inclividuals breathing pure oxygen obtain full saturation of their hemoglobin, whereas those with right to left shunts do not. Oxygen hemoglobin dissociation curves indicate that increases to full oxygen saturation of hemoglobin are accompanied by marked increases of the oxygen tension. WVhen breathing oxygen fails to produce full saturation, relatively little change in oxygen tension oc...

The headache histories obtained from clinical interviews of 600 patients were analysed by computer to see whether patients could be separated systematically into clinical categories and to see whether sets of symptoms commonly reported together differed in distribution among the categories. The computer classification procedure assigned 537 patients to the same category as their clinical diagno...

Tension introduced into peripheral nerves during their surgical repair may reduce the success of this procedure. Two mechanical factors are important; the tension required to effect a repair, and the rate at which this tension changes after surgery. These two factors have been investigated in the rat sciatic nerve. The results show an increasing resistance to elongation of the nerves with incre...

background: metabolic derangements in type 2 diabetes mellitus (t2dm) are likely to affect skeletal muscle contractile functions adversely. levo-carnitine improves muscle contractile functions in healthy humans and rats and corrects metabolic derangements in t2dm. therefore, it is likely to improve muscle contractile functions in t2dm as well. this study was designed to determine the effect of ...

suspension polymerization processes are significantly important in polymer bead formation. one of the important factors for bead size control in these processes is variation in surface tension. in this research, the prediction of optimum concentration of a surface active agent was investigated on the basis of the experimental surface tension diagrams. the experimental data show that the desired...
