High-resolution vacuum ultraviolet photoabsorption cross sections of CO2are required for modeling airglow emissions from the Martian and Venusian atmospheres and for photochemical models of those and Earth’s atmospheres. We report cross section measurements between 91000 and 115000 cm−1 (87–108 nm) at spectral resolutions of 1.15 cm−1 (91000 to 102000 cm−1) and 0.58 cm−1 (102000 to 115000 cm−1)...

Gouveia et al. [3] show how to model the Hop Constrained Minimum Spanning tree problem as Steiner tree problem on a layered graph. Following their ideas, we provide three possibilities to model the Hop Constrained (HC) Connected Facility Location problem (ConFL) as ConFL on layered graphs. We show that on all three layered graphs the respective LP relaxations of two cut based models are of the ...

With a view to examine the effects of defined doses of retinyl palmitate (Vit. A) on limb morphogenesis and their effects at the critical time in mouse embryos, pregnant Swiss Webster albino mice were administered retinyl palmitate (10000 or 15000 IU/kg, i.p.) on different days of pregnancy. Vitamin A in 15000 IU/kg, i.p. dose was most effective as produced malformations in the forelimbs by day...

Size and proportions of the postcranial skeleton differ markedly between Australopithecus afarensis and Homo ergaster, and between the latter and modern Homo sapiens. This study uses computer simulations of gait in models derived from the best-known skeletons of these species (AL 288-1, Australopithecus afarensis, 3.18 million year ago) and KNM-WT 15000 (Homo ergaster, 1.5-1.8 million year ago)...

the flow characteristics around an elliptic cylinder with an axis ratio of ar=2 located near a flat plate were investigated experimentally. the elliptic cylinder was located on the inside and outside a turbulent boundary layer region whose thickness (δ) is 0.38b. the reynolds numbers based on the height of the cylinder cross-section were 15000 and 30000. measurements of mean velocity and turbul...

mycotoxins are secondary metabolites produced by fungi following their infestation of food crops.one of the effective approaches to control aflatoxicosis is the use of adsorbents. the aim thusfollowed in the present study was a comparison of various adsorbents viz. bentonite, zeolite, vs. anorganic commercial adsorbent (mycosorb) and a mineral – organic commercial adsorbent (biotox)regarding th...
