RESUMO
The x-ray bremsstrahlung spectrum emitted by the electron population in a 14.5 GHz ECR plasma source has been measured using a NaI(Tl) detector, and hence the electron temperature of the higher energy electron population in the plasma has been determined. The x-ray spectra for Ne and Ar gases have been systematically studied as a function of inlet gas pressure from 7 × 10(-7) mbar to 7 × 10(-5) mbar and for input microwave power â¼1 W to â¼300 W. At the highest input power and optimum pressure conditions, the end point bremsstrahlung energies are seen to reach â¼700 keV. The estimated electron temperatures (T(e)) were found to be in the range 20 keV-80 keV. The T(e) is found to be peaking at a pressure of 1 × 10(-5) mbar for both gases. The T(e) is seen to increase with increasing input power in the intermediate power region, i.e., between 100 and 200 W, but shows different behaviour for different gases in the low and high power regions. Both gases show very weak dependence of electron temperature on inlet gas pressure, but the trends in each gas are different.

There is a strong correlation between gingival inflammation and clinical and sub-clinical ascorbic acid deficiency. This has created a demand for a handy diagnostic test to detect the ascorbic acid deficiency. The aim of this work was to find out the efficacy of one such test, i.e. the modified Lingual Ascorbic Acid Test (LAAT). To find out the significance of ths LAAT, it was compared with plasma ascorbic acid levels and then confirmed statistically. Our findings suggest that with this simple, reliable and inexpensive method, the dental practitioners can conveniently assess the ascorbic acid status of their patients.

The corollary follow up study carried presents variation in electrolyte content of serum during menstrual, follicular, ovulatory and luteal phases of menstrual cycle. Variation in sodium, potassium and chloride were found to be parallel with each other. Their level increase significantly from follicular to ovulatory phase and falls significantly during luteal phase. Bicarbonate levels are higher in follicular and luteal phases while they are lower in menstrual and ovulatory phases.

A variety of tests like FEV0-76, FEV1, PFR, MEFR is in use for assessment of ventilatory function of the lungs. Each of them has some marginal advantage over the other. It is, therefore, necessary to find out their relative merits and choose the one which can provide the maximum information in a reasonably short time. In this project, a norm of all the above tests for the people of Gujarat of age group 18-20 years has been found, the relative merit of the tests has been discussed and the velocity of air flow at 0.3 sec of expiration has been suggested as the single measurement which may conveniently replace all the other above.
