To achieve the automation of blast furnace operation, an automatic control system for hot metal temperature (HMT) was developed. Nonlinear model predictive (NMPC) which predicts up to ten-hour-ahead HMT and calculates appropriate actions pulverized coal rate (PCR) constructed. Simulation validation showed that NMPC algorithm generates similar those by operators can be maintained within ±10 °C s...

Hot spring or hot spa bathing (Onsen) is a traditional therapy for the treatment of certain ailments. There is a common belief that hot spring bathing has therapeutic effects for wound healing, yet the underlying molecular mechanisms remain unclear. To examine this hypothesis, we investigated the effects of Nagano hot spring water (rich in carbonate ion, 42°C) on the healing process of the skin...

Menopause is coincident with ovarian failure in women, resulting in a relatively rapid fall in levels of estrogens. Although there is no comparable hormonal event in men, some do have hot flashes. In Sweden, it was found that 33.1% of noncastrated men reported hot flashes [1]. The underlying mechanisms for this are not known. In women, hot flashes are the most common symptom of menopause and ar...

BACKGROUND Although many studies have documented health effects of ambient temperature, little evidence is available in subtropical or tropical regions, and effect modifiers remain uncertain. We examined the effects of daily mean temperature on mortality and effect modification in the subtropical city of Guangzhou, China. METHODS A Poisson regression model combined with distributed lag non-li...

Two archival studies examined the relation between year-to-year shifts in temperature and violent and property crime rates in the United States. Study 1 examined the relation between annual average temperature and crime rate in the years 1950-1995. As expected, a positive relation between temperature and serious and deadly assault was observed, even after time series, linear year, poverty, and ...

The temperature and composition of Earth's mantle control fundamental planetary properties, including the vigor of mantle convection and the depths of the ocean basins. Seismic wave velocities, ocean ridge depths, and the composition of mid-ocean ridge basalts can all be used to determine variations in mantle temperature and composition, yet are typically considered in isolation. We show that c...

Several optimal discharge pressure correlations for transcritical CO2 heat pump in literature have been discussed in this paper. Most of them are related to the ambient temperature, the evaporation temperature and the gas cooler outlet temperature. A revised optimal discharge pressure model as the function of ambient temperature and water outlet temperature is developed based on earlier experim...

BACKGROUND The current typical drying methods for red ginseng are sun drying and hot-air drying. The purpose of this study was to investigate drying characteristics of red ginseng by using far-infrared drying. METHODS The far-infrared drying tests on red ginseng were conducted at two drying stages: (1) high temperature for 24 h drying and (2) low temperature drying until the final moisture co...
