The temperature and nuclear composition of the crust and ocean of an accreting neutron star depend on the mix of material (the ashes) that is produced at lower densities by fusion of the accreting hydrogen and helium. The hydrogen/helium burning is thermally stable at high accretion rates, a situation encountered in weakly magnetic (B ≪ 10 G) neutron stars accreting at rates Ṁ > 10M⊙ yr −1 and ...
statement of problem: burning mouth syndrome (bms) is characterized by a burning sensation in the tongue or other oral sites, usually in the absence of clinical and laboratory findings. purpose: the aim of this study was to evaluate the main epidemiological and clinical features involved in burning mouth syndrome in zahedan; southeast of iran. materials and methods: in this case series study, 8...
background around 30% of suicides are committed by burning. the problem of self-immolation remains a crisis even after population based interventions and still a considerable proportion of admissions of burn ward is belonged to suicide cases. objectives this study was designed to present the epidemiologic profile of these patients and compare completed self-immolation and attempted ones. patien...
Suppose, for example, that you are an economist asked to advise Congress on legislation limiting the use of carbon based fuels. If you knew that burning such fuels at the present rate would so heat the surface of the planet that life would end in two centuries, you would have little difficulty endorsing any necessary legislation, however burdensome. If, on the other hand, you knew that burning ...
Neutron stars, with their strong surface gravity, have interestingly short timescales for the sedimentation of heavy elements. Recent observations of unstable thermonuclear burning (observed as X-ray bursts) on the surfaces of slowly accreting neutron stars (< 0.01 of the Eddington rate) motivate us to examine how sedimentation of CNO isotopes affects the ignition of these bursts. We further es...
burning mouth syndrome (bms) is a relatively common disease that can severely affect the quality of life of the patient. it causes chronic orofacial pain or oral burning sensation even in the absence of any detectable organic cause. the etiology of bms is complex and multifactorial. it has been associated with menopause, trigger events and even genetic polymorphisms. although its etiology remai...
The thermal environment in small and moderate-scale pool flames is studied by Large Eddy Simulation and the Finite Volume Method for radiative transport. The spectral dependence of the local absorption coefficient is represented using a simple wide band model. The predicted radiative heat fluxes from methane/natural gas flames as well as methanol pool burning rates and flame temperatures are co...
Burning Mouth Syndrome (BMS) is a chronic pain condition characterized by an intraoral burning sensation and absence of oral mucosal lesions disturbances in laboratory findings. symptoms usually affect the anterior two-thirds tongue, its lateral borders, hard palate labial mucosa, but other cavity sites may also be affected. Taste alterations decrease salivary flow rate frequently accompany sym...
improvement of soil properties through sustainable agriculture requires suitable management of plant residues. this study was conducted to investigate the effect of different types and managements of plant residue on soil physical properties in a field experiment as factorial based on rcbd with three replicates. the first factor was residue type including barley straw and alfalfa residue, and t...
