Background: The cold-adapted Idiomarina sp. 185 from Antarctic shoreline sediment and the mesophilic A19 brackish Lake Faro (Italy) were screened for their efficiency in biosurfactant production by a temperature-mediated approach, when grown rich culture medium mineral supplemented with biphenyl. Methods: oxidation of polychlorobiphenyls standard screening tests performed, i.e., E24 index detec...

We use the algorithm of Cole et al. (2000) to generate merger trees for the first star clusters in a ΛCDM cosmology under an isotropic UV background radiation field, parametrized by J21. We have investigated the problem in two ways: a global radiation background and local radiative feedback surrounding the first star clusters. Cooling in the first halos at high redshift is dominated by molecula...

In his classic work on the economics of fertility, Becker (1960) suggests that children are likely “normal.” We examine this contention. Our first step is documenting an empirical regularity about the cross section of non-Hispanic white married couples in the U.S.: When we restrict comparisons to similarly-educated women living in similarly-expensive locations, completed fertility is positively...

Post-transitional labour markets of the Central and East European countries have been characterised by marked regional differences. This paper will concentrate on the spatial pattern of job creation, determined by the allocation decisions of foreign and domestic investors. Regions with the highest employment rates may boast high doses of FDI inflows, while low employment regions have been suffe...

We study the wealth distribution in Bewley economies with idiosyncratic capital income risk. We show analytically that under rather general conditions on the stochastic structure of the economy, a unique ergodic distribution of wealth displays a fat tail. © 2015 Elsevier Inc.

There is evidence for developmental origins of vascular dysfunction yet little understanding of maturation of vascular smooth muscle (VSM) of regional circulations. We measured maturational changes in expression of myosin phosphatase (MP) and the broader VSM gene program in relation to mesenteric small resistance artery (SRA) function. We then tested the role of the sympathetic nervous system (...
