Recently research shows that heterogeneous model is needed to explain some complex combustion behaviors in SHS. However, more heterogeneous details be considered more difficulties will be faced. A micro-heterogeneous & macro-homogeneous model is proposed in this paper based on some previous works for this problem. Combustion compact is divided into lots of little units, which are composed of a ...

As an alternative source of off-grid electric power, solar home systems (SHS) stand out above all other options (e.g., wind, hydro, geo-thermal, tidal systems) because of their wide-scale potential at latitudes less than 45◦ north or south of the Equator where daily solar irradiance is more constant throughout the year and where the bulk of the Third World’s population live. A questionnaire-bas...

The objective of this study is to introduce an abstraction procedure that applies to a general class of dynamical systems, that is to discrete-time stochastic hybrid systems (dt-SHS). The procedure abstracts the original dt-SHS into a Markov set-chain (MSC) in two steps. First, a Markov chain (MC) is obtained by partitioning the hybrid state space, according to a controllable parameter, into no...

PURPOSE: The deterioration of elements of steel hydraulic structures (SHS) on our nation’s lock system is caused by combined effects of several complex phenomena: corrosion, cracking and fatigue, impact, and overloads. This Coastal and Hydraulics Engineering Technical Note presents examples of deterioration and a method for predicting future deterioration based on current conditions. In a compa...

The Grignard metathesis (GRIM) polymerization of 3-alkylthiophenes proceeds by a quasi“living” chain growth mechanism, not by a step growth process. Kinetic studies of the Grignard metathesis polymerization of 2,5-dibromo-3-alkylthiophenes showed that the molecular weight of poly(3-alkylthiophenes) is a function of the molar ratio of the monomer to nickel initiator, and conducting polymers with...

nano-sized batio3 powders with particular nb concentrations were prepared by rotary- hydrothermal (rh) method. hydrothermal method was used at 180 °c for 5 hours with new ti pressure and the teflon vessel was rotated at a speed of 160 rpm during the hydrothermal reaction. new hydrothermal method was used instead of previous solid state reaction for the system batio3±nb2o3 in high temperature to...

Due to serious environmental problem and strict regulations to control pollution, researchers across the globe are putting their effort to find clean, renewable, greener and cost effective method to produce biochemical from biomass. The aim of this article was to highlight the method to extract phenolic compounds from crude pyrolysis oil using switchable hydrophilicity solvents (SHS). The pyrol...

This document describes the working environment developed by ESCoM laboratory (Equipe Sémiotique Cognitive et Nouveaux Médias, Fondation Maison des Sciences de l’Homme) during the ASA-SHS project (Audiovisual Semiotic Workshop for Human and Social Sciences). ASA-SHS is a R&D project financed by the French National Research Agency (ANR, Programme Blanc 2008) and targets to develop strategies of ...

Aim: To explore the experiences of self-reported health (SRH) of 6-year-old boys and girls. Background: The goals for the Swedish School Health Services (SHS) are to identify health problems, take measures to prevent illness, and promote health. One approach used to achieve this is the use of the Health Dialogue (HD) questionnaire. The HD is offered at three occasions during compulsory school a...

spherical granules of the superionic conductor β/β́ lizr2(po4)3 in the range of sub 100 nm sizewere synthesizedvia freeze drying methodand fully reviewed in all aspects. samples were characterized by the x-ray diffractometry (xrd), the thermal analysis (tg, dsc), thefourier transform infra-red spectroscopy (ftir) and the scanning electron microscopy (sem).their structuredepends largely on the me...
