background: happiness as one of the main positive health indicators has drawn more attention in recent years among policy makers and health system managers. there are few studies performed to measure happiness in population-based settings in iran. in response to this need, our study tends to assess iranians subjective happiness in tehran, capital city of iran. m aterials and methods: present st...

Macro measurement is a long and arduous process that impinges upon the system of national accounts. The challenge it raises is driven by the demand of economic policy. In present time the need will arise with sustainable growth that mixes environmental concern and development policy. It calls for no less than a sea change in national accounting, from a system of income and expenditure accounts ...

let g be a locally compact group, and let ω be a weight on g. we show that the weightedmeasure algebra m(g,ω) is amenable if and only if g is a discrete, amenable group andsup{ω(g) ω(g−1) : g ∈ g} < ∞, where ω(g) ≥ 1 (g ∈ g) .

In previous publications (SHAFRITZ, D. A., DRYSDALE, J. W., AND ISSELBACHER, K. J. (1973) J. Biol. Chem. 248, 3220-3227 and SHAFRITZ, D. A. (1974) J. Biol. Chem. 249, 81-88) we reported the isolation and translation of RNA fractions with messenger activity from membrane-bound and free polysomes of rabbit liver with evidence for specilic synthesis of albumin and ferritin in a reticulocyte cell-f...

I N Neurospora, L-histidinol is the immediate precursor of L-histidine, as shown by the isolation of L-histidinol dehydrogenase and the study of its catalytic functions (AMES 1957; CREASER, BENNETT and DRYSDALE 1965). The failure of histidine mutants, with the histidinol dehydrogenase function intact, to grow on histidinol, suggests that histidinol cannot enter the cell. However, CATCHESIDE ( 1...

Lee and Drysdale [13] and Sharir [16] have given suboptimal algorithms for computing the Voronoi diagrams of line-segments or discs in the plane. This paper adapts their methods to constructing the Voronoi diagram for disjoint convex sites in three dimensions. Let be an upper bound on the number of features in any diagram involving sites in three dimensions. Even for point sites, is , so it is ...
