Iron ore reduction is a primary unit operation in current metallurgy processes and dominates the energy consumption and greenhouse gas(GHG)emissions of the iron-making process,Therefore,even a slight improvement of the energy efficiency or GHG emissions of iron ore reduction would yield considerable benefits to the cost of pig iron and,more importantly,to mitigation of the associated carbon *** current study presents a discrete model that describes the iron ore reduction process for a single *** transient reaction progress can be pre.icted and is validated against experimental measurements under various operating conditions,including different reducing gases and *** effects of pressure,isothermality,gas composition,and flow rate on reduction are *** reduction rate increases significantly with increasing pressure until 5 atm,and the entire reduction process occurs more slowly under non-isothermal conditions than under isothermal *** work provides a solid foundation for the development of a comprehensive particulate system model that considers both heat and mass transfer.

Management in Sustainable Tourism Development of Serbian Spas

引用

Journal of Agricultural Science and Technology(A) 2012年第12期2卷 1356-1363页

作者： Biljana I1ic Dragica Stojanovic Violeta Jovanovic Dragan Mihajlovic Department of Faculty of Management University of Megatrend Belgrade Zajecar 19000 Serbia

Since Serbia disposes with significant natural potentials, it could have been among the most attractive countries in europe only if the historical circumstances had been different. existing natural resources and possibilities for their improvement demand planned strategy to make them efficient. Tourism, as a significant instrument of development, can and should take an active part in the strategy of sustainable development. Special attention in the paper is paid to the development of Vrnjacka Banja Spa as it is one of the main tourist destinations in Serbia. The strengths, weaknesses, opportunities, and threats of a business venture （SWOT） analysis offers the basic elements for defining the strate.ic direction and program priorities, measures and targets for improving the overall development of spas in Serbia. To identify the SWOT factors, we used materials from a number of studies on Serbian tourism, surveys on tourists in Vrnjcka Banja Spa and analysis of the market and competition. The SWOT analysis proves that the priority in development of spas in Serbia is attractiveness of the destination which involves the spa-health tourism with great potential in complementary forms of tourism, such as sport-recreational, cultural, transit and hunting tourism. It means that the future strategy should be based on improving and involving modern spa products. It means improving and maximizing marketing so as to make the tourist destination attractive. It further implies maximum investment in modern tourist products.

Thermal conductivity of systems with a gap in the phonon spectrum

引用

Chinese Physics B 2018年第7期27卷 424-430页

作者： e Salamatov Udmurt Federal Research Center Ural Branch of the Russian Academy of Sciences

An original theore.ical model for describing the low-temperature thermal conductivity in systems with a region of forbidden values （a gap） in the phonon spectrum is proposed. The model is based on new experimental results on the temperature dependence of the phonon diffusion coefficient in nanoceramics and dielectric glasses which showed a similar anomalous behavior of the diffusion coefficient in these systems that may be described under the assumption of a gap in the phonon spectrum. In this paper, the role of the gap in low-temperature behavior of the thermal conductivity, ~＇（T）, is analyzed. The plateau in the temperature dependence of the thermal conductivity is shown to correlate with the position and the width of the gap. The temperature dependence of thermal conductivity of such systems when changing the scat- tering parameters related to various mechanisms is studied. It is found that the umklapp process （U-processes） involving low-frequency short-wavelength phonons below the gap forms the behavior of the temperature dependence of thermal con- ductivity in the plateau region. A comparison of the calculated and experimental results shows considerable possibilities of the model in describing the low-temperature thermal conductivity in glass-like systems.
