Outflows are common in many astrophysical systems which contain black holes and neutron stars. Difference between stellar outflows and outflows from these systems is that the outflows in these systems have to form out of the inflowing material only. The inflowing material can form a hot and dense cloud surrounding the compact object either because of centrifugal barrier or a denser barrier due ...

This work primarily investigated the pyrolysis of smalls scale fixed bed reactor using plastic wastes type LDPE during slow (non-isothermal) in a batch to assess effect different temperatures on product yield and heating value. The calorie bomb Parr Instrument was performed value pyro-oil at 250, 275, 300oC. obtained higher 300 oC while increased temperature will affect increase pyro-oil. highe...

this research is aimed to undertake a comparative study on stability and thermal degradation kinetics of un-irradiated and high energy protons irradiated polyvinyl butyral (pvb) based on weight loss analysis and non-isothermal approaches. the weight loss by the un-irradiated pvb upon heating was found to be in two stages but due to high energy protons accelerated exposure following by chemical ...

To elucidate the phase transformation behaviors for 38MnB5Nb ultra high-strength steel, continuous cooling (CCT) and time-temperature-transformation (TTT) curves were determined by thermal expansion method with different rates isothermal temperatures after complete austenization. be more accurate, microstructure was observed hardness tested. The results showed that starting ending of austenite ...

Heat resistance of microorganisms can be affected by different influencing factors. Although, the effect of heating rates has been scarcely explored by the scientific community, recent researches have unraveled its important effect on the thermal resistance of different species of vegetative bacteria. Typically heating rates described in the literature ranged from 1 to 20°C/min but the impact o...

This paper illustrates an application of a technique for predicting the thermal characteristics of a bidirectional thermocycling device for polymerase chain reaction (PCR). The micromilling chamber is oscillated by a servo motor and contacted with different isothermal heating blocks to successfully amplify the DNA templates. Because a comprehensive database of contact resistance factors does no...
