A new, rapid and versatile microassay for cellular retinol-binding protein has been developed based on separation of bound and free ligand by means of Lipidex-1000, a hydrophobic Sephadex derivative.This requires quantitative manipulation of retinol in aqueous solution.The tendency of retinol to adhere to glass and plastic surfaces was overcome by
Microorganisms are frequently organized into crowded structures that affect the nutrients diffusion.This reduction in metabolite diffusion could modify the microbial dynamics, meaning that computational methods for studying microbial systems need accurate ways to model the crowding conditions.We previously developed a computational framework, terme
ABSTRACT We conducted a global characterization of the microbial communities of shipping ports to serve as a novel system to investigate microbial biogeography.The community structures of port microbes from marine and freshwater habitats house relatively similar phyla, despite spanning large spatial scales.As part of this project, we collected 1,21
In contrast to the industry, in the agricultural production process, specific factors intervene, which determine peculiarities in the use of labor, means of production Ball Marker and work items.The specific factors acting in the agricultural production process: land, plants, animals, soil and climate conditions, give special features regarding the
Using CHAMP magnetic field data we study the behaviour of the geomagnetic field during two mid latitude eclipses on 21 June 2001 and 22 September 2006.The possible influence of the eclipses on different ionospheric current systems, as seen in the magnetic field measured by CHAMP, is discussed.It is expected that the blocking of solar radiation duri
