Abstract Sea cucumbers live in ponds and coastal with different salinity. This study aims to determine the range of salinity support growth survival sea cucumber juveniles. The research container used was a transparent fiberglass tank capacity 30 L as many 8 tanks. juveniles were 4 individuals /tank an average size between 55-68 mm. Each equipped plastic bottle filled coral fragments white sand...

The design of concrete elevated water tanks involves several kinds uncertainties. Traditionally, the these structures is based on a deterministic analysis. Partial safety factors prescribed in codes are applied to take into account uncertainties and ensure sufficiently safe design. However, this approach does not allow rational evaluation risk related structural failure consequently its reliabi...

Štúdium viazania stopových prvkov v sedimente vodnej nádrže Ružín Pre účely posúdenia možnosti využitia fyzikálnych a fyzikálno-chemických metód separácie, vybraná vzorka sedimentu z Ružína bola podrobené 5-stupňovej procedúre sekvenčnej extrakcie (SE) podľa Tessiera (Tessier et al., 1979) a Horowitza (Horowitz, 1991). Vo výluhoch bolo stanovované zastúpenie konštitučných (Fe, Mn, Ca a Mg) ako ...

in tannins and gaining optimal adjustment to tannin-rich diet requires time; thus, skilfully, goats prefer to safeguard their advantage in utilizing food that is available to them at all seasons. There is a positive interaction between the enhanced recycling rate of urea and a superior digestion of such food in goats adapted to harsh environment. The rumen plays an important role in the develop...

Preliminary observations indicated that the grass shrimp, Palaemonetes pugio, parasitized by the isopod, Probopyrus pandalicola, captured significantly fewer prey items (Daphnia) and exhibited reduced activity compared to unparasitized conspecifics. Further research focused on elucidating the factors involved in altering the shrimp’s behavior. When viewed from above in an opaque container, acti...
