Observed spectra of Active Galactic Nuclei (AGN) and luminous X-ray binaries in our Galaxy suggest that both hot (∼ 10K) and cold (∼ 10K) plasma components exist close to the central accreting black hole. Hard X-ray component of the spectra is usually explained by Compton upscattering of optical/UV photons from optically thick cold plasma by hot electrons. Observations also indicate that some o...

Temperature affects all biological functions and will therefore modulate ecologically significant interactions between animals and their environment. Here, we examined the effect of ambient temperature (Ta) on the thermal biology and energy budget in striped hamsters acclimated to cold (5°C), warm (21°C) and hot temperatures (31°C). Thermoneutral zone (TNZ) was 22.5-32.5°C, 25-32.5°C and 30-32....

This paper examines the experience of fourteen developed countries for which there are about thirty years of quarterly inflation-adjusted housing price data. Price dynamics is modeled as a combination of a country-specific component and a cyclical component. The cyclical component is a two-state Markov switching process with parameters common to all countries. We find that the latent state vari...

The presence of a hot dark matter component has been hinted at 3σ by a combination of the results from different cosmological observations. We examine a possibility that pseudo Nambu-Goldstone bosons account for both hot and cold dark matter components. We show that the QCD axions can do the job for the axion decay constant fa . O ( 1010 ) GeV, if they are produced by the saxion decay and the d...

The X-ray data obtained with XMM-Newton is used to investigate the complex structure of the gas in the atmosphere of the Virgo cluster around M87. We construct a simple model for the temperature and density distribution. This model implies that the cumulative mass of the cluster gas is a power-law of its entropy index, kT n−2/3, similar to the Hydra cluster. This supports the idea that such pow...

Tea is known as nature low calorie wonder drink. Consumption of hot tea decoction became popular from the ancient times. Currently researchers observed that many secondary metabolites that are heat sensitive might get destroyed on heating. Moreover people, who are permanently live at higher altitude or the members of high altitude expedition team, are deprived of various tea brewing facilities ...

Recent experiments in our laboratory have revealed a genetic correlation of the sensitivity of inbred mouse strains to different assays of nociception using noxious heat stimuli. An open question is whether the property of the noxious stimulus underlying the genetic correlation is heat specifically or simply a temperature (hot or cold) in the noxious range. The existing electrophysiological, ps...

objective: vanillosmopsis arborea baker (asteraceae) has high economic value from chapada to araripe and its bark essential oil is a potential source of alpha-bisabolol. the present study aimed to elucidate the antinociceptive and antipruritic properties of the essential oil of v. arborea baker (eova) in mice. materials and methods: the antinociceptive activity was assessed using the capsaicin,...

Patients with acute myocardial infarction are frequently not fed hot and cold liquids because of possible deleterious effects on heart rate, blood pressure, and cardiac rhythm. In an attempt to identify and quantify such changes, hot liquid with a temperature in excess of 70 degrees C and cold liquid at an average temperature of 7 degree C were ingested by 20 patients within 36 hours of documen...

Many decisions related to cigarette smoking require people in an affectively neutral, or "cold," state to predict how they will feel or behave when in a craving, or "hot," state. Research in other domains has revealed that individuals in cold states often underestimate the impact of being in a hot state on their own future behavior. In a study testing whether this is true of cigarette craving, ...
