When developing the composition of recipes for complete dry combined feeds in industrial aquaculture, addition to their balance terms basic nutrients, it is necessary pay attention presence a number irreplaceable biologically active feed components them. Among them, along with vitamins and minerals, are carotenoids – natural pigments contained food fish. Carotenoids play different role metaboli...

Gelation speed is directly proportional to the concentration of calcium. Although the kinetics of gelation are altered by the source of calcium, the final alginate gel strength nor the resistance to calcium diffusion are altered. Calcium chloride reaches a gel strength plateau fastest ( 100 s), followed by calcium lactate ( 500 s) and calcium gluconoate ( 2000 s). Calcium chloride is the best o...

A new generation of technologies allows firms to track online consumer behavior with increasing granularity, and to share this information with other firms. This promise of information sharing has driven considerable interest from firms; and its potential for monetization has allowed a large number of online and web services to be available free of charge to consumers (in exchange for behaviora...

Most of the exoplanets detected up to now transit in front their host stars, allowing for generation transmission spectra; study exoplanet atmospheres relies heavily upon accurate analysis these spectra. Recent discoveries mean that atmospheric signals from low-mass, temperate worlds are becoming increasingly common. The observed depth planets is small and more difficult analyze. Analysis simul...

ABSTRACT In the caviar software package, a standard tool for astrometry of images from Cassini imaging science subsystem (ISS), Gaussian fitting is used to measure centre point-like objects, achieving typical precision about 0.2 pixels. this work, we consider how alternative methods may improve on this. We compare three traditional centroiding methods: two-dimensional fitting, median, and modif...
