The merger of two neutron stars leaves behind a rapidly spinning hypermassive object whose survival is believed to depend on the maximum mass supported by the nuclear equation of state, angular momentum redistribution by (magneto-)rotational instabilities, and spindown by gravitational waves. The high temperatures (∼5 − 40MeV) prevailing in the merger remnant may provide thermal pressure suppor...

In this paper the quantum heat transport equation (QHT) is applied to the study of thermal properties of Planck gas, i.e. gas of the massive particles with mass equal Planck mass, Mp = (h̄c/G)1/2 and relaxation time equals Planck time, τp = (h̄G/c5)1/2. The quantum of thermal energy for Planck gas, EPlanck = 1019 GeV and quantum thermal diffusion coefficient DPlanck = (h̄G/c)1/2 are calculated. Wi...

A low cost, simple solar heating system consisting of an active collector with an In-Floor Heat Distribution and Storage (IFHDS) system was developed in response to the energy crisis of the 1970s. A two-dimensional finite difference model was developed and used to simulate the performance of IFHDS system cross-sections. Simulation runs were conducted with a steady-periodic model for the tempera...

The unsteady free convection flow between two long vertical parallel plates withvariable temperature and mass diffusion in the presence of the thermal radiation hasbeen presented. The governing dimensionless coupled linear partial differentialequations on the flow are solved by using the Laplace transform technique. TheExact solutions have been obtained for the fluid velocity, temperature and t...

We report the role of longand short-range order on the thermal conductivity and mode relaxation times of a model Si0.5Ge0.5 alloy using molecular dynamics simulation. All interactions used the Stillinger-Weber potential and the Si and Ge atoms differed only by their mass. The simulated alloys were generated using a Monte Carlo approach to decouple the short-range order from the long-range order...

ionomers are generally described by copolymers having either acrylic or methacylic acid as one component and the other component is mostly either ethylene or styrene. the objective of this research was to study the thermal behaviour and stability of ionomers of styrene with some alkali metal acrylates. these materials have been synthesized by neutralization of the respective copolymer containin...

An analytical investigation is conducted to study the unsteady free convection heat and mass transfer flow through a non-homogeneous porous medium with variable permeability bounded by an infinite porous vertical plate in slip flow regime while taking into account the thermal radiation, chemical reaction, the Soret number, and temperature gradient dependent heat source. The flow is considered u...

We investigate the dependence of stellar properties on the mean thermal Jeans mass in molecular clouds. We compare the results from the two largest hydrodynamical simulations of star formation to resolve the fragmentation process down to the opacity limit, the first of which was reported by Bate, Bonnell & Bromm. The initial conditions of the two calculations are identical except for the radii ...

A detailed model of the Net Zero Energy Town House in Toronto is developed in TRNSYS. The incorporation of thermal mass into the building envelope has been demonstrated to contribute to the enhancement of occupant comfort through the reduction of indoor temperature fluctuations. It has also been shown to cause a decrease in the overall energy consumption associated with the heating and cooling ...

Thermal-based germination models are widely used to predict germination rate and germination timing of plants. However, comparison of model parameters between large numbers of species is rare. In this study, seeds of 27 species including 12 C4 and 15 C3 species were germinated at a range of constant temperatures from 5 °C to 40 °C. We used a modified thermal time model to calculate germination ...
