BACKGROUND Adequate application of the static and dynamic anthropometric measures of pre-school children in ergonometric design of children's playground equipment should eliminate all dangers and difficulties in their use. Possibilities of injuries, insecure movements, discomfort able positions and some other dangerous actions may be minimized; and safety and health protection of pre-school chi...

background: the radioactivity levels in sediment and rock samples of i̇kizdere and kaptanpaşa valley have been determined. to our knowledge, there seems to be no information about radioactivity level in the i̇kizdere and kaptanpaşa valley sediments and rocks so far. materials and methods: the average radium equivalent activity (raeq), the total absorbed dose rate (d), the external risk index (hex...

1. Values for total body vitamin B,, were calculated for eighteen patients by giving a tracer dose of radioactive cyanocobalamin and measuring the radioactivity and microbiological activity in liver biopsies obtained at laparotomy. 2. The values for total body vitamin B,, ranged from 960 to 5984pg with a mean of 2528 pg. Five values were greater and thirteen less than the mean. 3. Significant c...

A 54-year-old patient was found to have an aldosterone-producing microadenoma measuring 2.5 mm in diameter. Although adrenal venography by selective catheterization had failed to demonstrate the tumour, adrenal scintiscan using 131I-19-iodocholesterol accurately localized the functional tumour in the right adrenal gland; a dexamethasone-modified adrenal scintiscan revealed complete suppression ...

pentacyclic aromatic ring, and any metabolite resulting from cleavage or alteration of the aro matic character of the hydrocarbon could not be identified unequivocally by this analytical method. Another technic for these studies was made avail able following the synthesis of 1,2,5,6-dibenzanthracene-9,10-C14(9) ; and by measuring the radio activity of tissues and their fractions following the a...

The water permeability of tissues was investigated by measuring the efflux of (3)HHO from previously loaded (in darkness) etiolated bean buds (Phaseolus vulgaris L. var. Red Kidney), pea epicotyl segments (Pisum sativum L. var. Alaska), and oat coleoptile segments (Avena sativa L. var. Garry). Red light, far red light, or darkness was applied at the time of transfer of tissue from labeled to un...
