Generally, it finds financing source matters for firms of different size, and the extent to which financing source matters for ...

adsorption of co2 on the surface of single-wall zigzag (5,0) and armchair (4,4) carbon nanotubes (swcnts) were studied through using density functional theory (dft) calculations. optimizations of geometric were performed at the b3pw91 level of 6-311++g** method standard basis set using gaussian 03 package of program [1]. structural models were optimized and adsorption energies, band gap, charge...

A total of 1752 strains of osrnophilic yeasts were isolated from honey and po]]ens. Fody-three strains Gf esmophilic yeasts produced po]yols, among whieh 6 strains produced erythritol in good yields. On the other hand, 52 osmophilic yeasts converted sucrose te fin]etooligosaccharides, among which 8 strains produced both extra and intracel]ular P-fructofuranosidase, which conyerted sucrose to fr...

Many species of tachinid flies are viewed as generalist parasitoids because what is apparently a single species of fly has been reared from many species of caterpillars. However, an ongoing inventory of the tachinid flies parasitizing thousands of species of caterpillars in Area de Conservación Guanacaste, northwestern Costa Rica, has encountered >400 species of specialist tachinids with only a...

BACKGROUND The use of a squalene-containing (AS03) pandemic vaccine for high-risk groups in England allowed vaccine effectiveness (VE) of such novel oil-in-water adjuvanted vaccine to be evaluated. METHODS Cases of laboratory-confirmed pandemic (H1N1)2009 influenza in England between November 2009 and January 2010 were followed up for history of pandemic (H1N1)2009 or 2009/10 seasonal influen...

OBJECTIVES To study the incidence and risk factors for retinopathy of prematurity (ROP) in the Netherlands. STUDY DESIGN Prospective, approximating population-based study that included infants with gestational age (GA) <32 weeks and/or birth weight (BW) <1500 g born in 2009.
