Game players express values related to self-expression through various means such as avatar customization, gameplay style, and interactions with other players. Multiplayer online games are now often integrated with social networks that provide social contexts in which player-to-player interactions take place, such as conversation and trading of virtual items. Building upon a theoretical framewo...

A new reaction mechanism generator RMG is used to automatically construct a pressure dependent kinetic model for the steam cracking of n-hexane. Comparison between simulated and pilot plant data shows that RMG is able to generate detailed reaction networks that accurately predict the conversion and the yields of the major products although none of the kinetic parameters are fit to the experimen...

DC lOO%-steam plasma characteristics were investigated for the application of halogenated hydrocarbon decomposition because steam plasmas are chemically reactive. However, plasma system generally requires complex subsystems such as steam generators and cooling units. The presented steam plasma system is a portable light-weight plasma generation system that does not require any gas supply unit. ...

There exists general agreement that the steam engine's rise in importance occurred at the same time as large increases in firm size and growing urbanization, but no consensus concerning the degree to which the steam engine served as an exogenous fo rce fueling urban growth. We reexamine the hypothesis that a leading brand of steam engine made by the Corliss Company fue led urbanization in the l...

Superheated steam drying technique has been known for a long time, but its application to food drying has received little attention. In this work, superheated steam was applied to dry fresh parsley (Petroselinum Cripsum). A mathematical model to simulate this drying process was developed by using mass and energy conservation equations for solid and steam phases. The resulting partial differenti...

Forced convective condensation in vertical channel is investigated numerically. The condensation boundary layers that occur due to temperature difference between the walls and saturation temperature of steam is simulated by the volume of fluid (VOF) method. The effect of variations in the hydraulic diameter, steam velocity, Re number and temperature difference between the wall and saturation te...

This paper presents entropy generation minimisation model of combined heat and power system. The turbine control valves and heater throttle valves were analysed. The high-pressure control valves regulate the mass flow rate of steam into the turbine, whereas the intermediate-pressure and lowpressure control valves the steam pressure of the turbine extracts 3 and 5. The steam of the turbine extra...

the biqian-10 block, located in henan oilfield of sinopic, contains many thin and interbedded reservoirs, which have been operated by cyclic steam stimulation for 20 years or more. therefore, it is a challenge to implement the conventional steam flooding. in order to improve the recovery of steam flooding, urea was used to assist steam flooding. urea can decompose into co2 and nh3, which are be...

This work presents the hydrogen production from steam gasification of palm kernel shell (PKS) at 700 C in the presence of 5% Ni/BEA and 5% Fe/BEA as catalysts. The steam gasification was performed in two-staged reactors to evaluate the effect of calcinations temperature and the steam to biomass ratio on the product gas composition. The catalytic activity of Ni/BEA catalyst decreases with increa...
