Opis:
This research aims at analyzing the optimum of low temperatures (12 ºC, 16 ºC, 20 ºC and temperature control (24 ºC)) used at the beginning of transport on the survival rates of goldfish juvenile (Carassius auratus L.), with the size of about 3 cm. Each time 20 goldfish is placed in 2 litres of water in transportation with closed systems for 8, 10 and 12 hours where the goldfish is transported at 21:00 pm. This research used an experimental method, Factorial Randomized Group Design, which consists of two factors that is, a four-level temperature factor and a three-level time factor and repeated three times. The parameters observed were the survival rate, water quality, duration of the process anesthesia, duration of the process recovery after transportation and pisciculture after transportation. The results showed the low temperature and time of transportation had a significant effect on the survival rate of goldfish (Carassius auratus L.) in transportation with closed systems. The optimum temperature and duration of time for transportation of goldfish (Carassius auratus L.) were: temperature of 16 °C and 12 hours of transportation time, with 98.33% survival obtained. This species of fish comes from the regions of Japan, South Korea, South-East China, Malaysia, Thailand, Vietnam, Indonesia, and Philippines. Currently, this fish is found worldwide as a breeding copy.

Opis:
A mathematical model for control by transient modes of gas flows in the long-distance gas pipeline is considered in the paper. The long-distance pipeline is considered in the model as the system of Line segments serially connected via compressor stations. Gas motion in such system is described by the non-linear system of equations of gas dynamics. In the frame of this model the integral parameters which determine the expenditure of energy and durations of the transient mode are introduced. These parameters can be used for formulation the problems for optimal control steady-state and transient modes of operation of main-gas pipelines.
