Abstract The ratio of stable carbon and nitrogen isotopes in the suspended particulate matter has been widely used to study processes occurring marine ecosystem. At same time, signals provided by isotope ratios coastal ecosystems can be difficult interpret, due several, often contradictory taking place simultaneously. In this study, we hypothesized that isotopic variation is predominantly affec...

Abstract Solar collectors are devices that enable the use of solar radiation, e.g., for hot water preparation or space heating. They playing an increasingly important role in Europe and around world, mainly due to easy availability sun, as energy source. The advisability their depends on a number factors, which climatic conditions extremely one. This paper presents results simulations collector...
