one school was assigned at random to receive a special 20-session risk\x=req-\ reduction intervention and one school served as a control. At a two-month follow-up, risk factor knowledge scores were significantly greater for students in the treatment group. Compared with controls, a higher proportion of those in the treatment group who were not exercising regularly at baseline reported regular e...

a 5\m='\-incompleteopen reading frame of 525 base pairs. The 3\m='\-untranslatedregion of 946 base pairs contains a repetitive DNA element of the rodent B1 family just between two canonical polyadenylation signals AATAAA, upstream of the poly(A) track. The deduced amino acid sequence for the Mr 24 000 proteins reveals significant homologies of 66\m=.\6,66, 65\m=.\2,63\m=.\1 and 64\m=.\5%with mo...

Several papers [1, 2, 3) 2 and Handbooks [4, 5] have been published during the past 20 years dealing with barrier req uirements for shielding against gamma radiation from radium. These publications have usually suggested lead for the barriers because a large proportion of the applications required restricted space and ready transportabi lity of the barrier and gamma-ray source. For h igh-energy...

Fe-, Fe -, and Sn-based complex oxides, namely, Fe2GeO4, CaFe2O4 and Ca 2SnO4 nanopowders were prepared via single -step mechanosynthesis performed at room temperature. The mechanically induced formation of a nanooxide product phase was followed by XRD, Fe Mössbauer spectroscopy, and NMR. It is demonstrated that the mechanosynthesis of the complex oxide can proceed very rapidly (up to 4 h) . Th...

Dose-response curves were obtained from forty male control subjects and forty male patients with duodenal ulcer from India on the subcutaneous histamine test. The body weight and maximal acid output (MAO) showed a positive correlation just significant at the 5%o level in control subjects (P=0 05) but not in patients with duodenal ulcer. The values of MAO on dose-response curves are comparable i...

Proteolytic activity, acid phosphatase activity and fructose concentration were measured in seminal plasma from 205 human semen samples. Certain routine sperm characteristics were also determined. High fibrinolytic activity was found and TAME-esterase and proteinase activity was also present in all specimens. The activity of all the proteolytic enzymes correlated positively with the acid phosph...

This paper describes the design and implementation of S W O R D , a scalable resource discov ery serv ice for w ide-area distributed sy stems. S W O R D locates a set of machines matching user-specifi ed constraints on both static and dy namic node characteristics, including both single-node and inter-node characteristics. W e ex plore a range of sy stem architectures to determine the appropria...
