In this work we analyze numerically different design configurations to be used in a R1234yf DMS cycle coupled with water source, transcritical CO2 heat pump for heating applications the building sector. Specifically, study temperature range proposed by European standard inlet/outlet temperatures of: 30 °C/35 °C, 40 °C/45 47 °C/55 °C and 55 °C/65 °C. Moreover, 25 °C/30 is also analyzed which exp...

The temperature-driven adaptation of the bacterial community in peat was studied, by altering temperature to simulate self-heating and a subsequent return to mesophilic conditions. The technique used consisted of extracting the bacterial community from peat using homogenization-centrifugation and measuring the rates of thymidine (TdR) or leucine (Leu) incorporation by the extracted bacterial co...

Many alphaviruses cause more severe disease in young animals than in older animals. The age-dependent resistance to severe disease is determined primarily by maturation of the host, but strains of virus can be selected that overcome the increased resistance of mature animals. Sindbis virus (SV) strain AR339 causes fatal encephalitis in newborn mice and nonfatal encephalitis in weanling mice, wh...

BACKGROUND AND THE PURPOSE OF THE STUDY Mechanical properties of films prepared from aqueous dispersion and organic solutions of Eudragit RL were assessed and the effects of plasticizer type, concentration and curing were examined. METHODS Films were prepared from aqueous dispersion and solutions of Eudragit RL (isopropy alcohol-water 9:1) containing 0, 10 or 20% (based on polymer weight) of ...
