Black holes pose great difficulties for theory since gravity and quantum theory must be combined in some as yet unknown way. An additional difficulty is that detailed black hole observational data to guide theorists is lacking. In this paper, I sidestep t... see more

Densities of ionic liquid (IL) 1-octyl-3-methylimidazolium hexaflu­oro­phosphate [OMIM][PF6] at high temperatures and high pressures were mea­sured. The measurements were made along 10 isotherms over a temperature range T = 278.15 to 413.15 K, a... see more

We study an indefinite metric G which was introduced by R. Mrugala and is defined on the contact phase space (P,?) of a homogeneous thermodynamical system. We describe the curvature properties and the isometry group of the metric G. We established an isom... see more

Geostationary satellite and radar analyses clearly illustrate preferential regions of thunderstorm occurrences over south Florida. A synoptic analysis of the associated weather patterns suggests that a moister lower and middle troposphere is conducive ... see more

We present here the results from dynamical and thermal models that describe a channeled lava flow as it cools by radiation. In particular, the effects of power-law rheology and of the presence of bends in the flow are considered, as well as the formation ... see more

Pictet’s experiment was front and center in the 18th/19th century debate concerning whether heat is a wave, or a particle. Pictet’s experiment is best understood by realizing that thermal radiation energy plays a significant role in heat transfer. It is a... see more

The multi-distributed activation energy model (multi-DAEM) is the most effective approach for outlining the kinetics model of biomass pyrolysis. The purpose of this study is to identify the optimal number and shape of the DAEM for sugarcane bagasse pyroly... see more

This work investigates computationally the spectroscopic and thermodynamics properties of the perylene molecule (C20H12) in the gas phase by utilizing a semi-empirical method [Hyper Chem8.0 and WinMopac7.0] programs, via (MNDO-PM3). This method is providi... see more

Internal flows in pipes are studied in greater depth and comprehensiveness in research. The computation done by using RANS equation. In particular, this study uses two equations turbulence model which is k-ε turbulence model. Mesh with 2×106 element is ... see more
