Health And Disease

The human body (primarily the intestinal tract, the oral cavity, and the skin) harbours approximately 1,000 different bacterial species. However, the number of archaeal species known to colonize man seems to be confined to a handful of organisms within the classEuryarchaeota(includingMethanobrevibacter smithii,M. oralis, andMethanosphaera stadtmanae). In contrast to this conspicuously low diversity ofArchaeain humans their unique physiology in conjunction with the growing number of reports regarding their occurrence at sites of infection has made this issue an emerging field of study. While previous review articles in recent years have addressed the putative role of particularly methanogenic archaea for human health and disease, this paper compiles novel experimental data that have been reported since then. The aim of this paper is to inspire the scientific community of “Archaeaexperts” for those unique archaeal organisms that have successfully participated in the human-microbe coevolution.

Simulation Results

A new physical vapor deposition source is developed to meet the challenges of barrier deposition for sub 100nm devices. The source employs multi-step process to deposit thin, conformal and uniform barrier films. This paper describes reactor scale modeling and simulation of deposition and etching plasmas used for barrier deposition. The modeling and simulation in tandem with experimental data demonstrate that the chamber can be used to independently control the particle fluxes as per the requirements of the deposition and etching steps. The simulation results were qualitatively used to optimize the ion flux uniformity by altering the magnetic fields near the wafer.

The Mathematical Model

Abstract Mathematical models including mass and energy conservation were developed in order to predict the outlet particles temperature and moisture. As the inlet air temperature increased, the outlet particles temperature increased as well and the outlet particles moisture decreased quickly. The outlet particles temperature and moisture changed a little as a function of the speed of rotation at the low inlet air temperature, while the outlet particles temperature and moisture increased very apparently with the speed of rotation increased at the high inlet air temperature. The error of the simulation results compared to the experimental data showed good accuracy for particles temperature and moisture content. The mathematical model performs well to predict the outlet particles temperature and moisture content.

AbstractThe present work deals with modeling and simulation of a pilot-scale bubbling fluidized bed gasifier (BFBG) for the gasification of high ash Indian coal. Taking into account different stages of coal gasification, such as drying, volatilization, gasification and combustion processes, a two-dimensional model with quadrilateral cells is developed using FLUENT 12.0 software. The model incorporates exchange of mass, momentum and energy between gaseous phase (phase 1) and solid phase (phase 2) using Eulerian–Eulerian approach. The solid phase is described by kinetic theory of granular flows. Four heterogeneous and four homogeneous reactions covering six species in gaseous phase (CO, CO2, H2, N2, O2 and H2O) and coal in solid phase are considered for the above process. The kinetics for the homogeneous reactions are described using eddy dissipation model available in FLUENT while that for heterogeneous reactions, a user-defined function (UDF) with Arrhenius kinetics is written in C language. The validation of the above model has been done using experimental data generated in a pilot-scale BFBG at Center Institute of Mining and Fuel Research (CIMFR), Dhanbad, India. The computed exit gas compositions as well as temperature profile inside the gasifier are in good agreement (within an error band of ±10%) with experimental data. The flow behaviors and volume fraction profiles of gas and solid phases in the bed zone and freeboard zone of the gasifier have also been predicted using this model.

Comparison With Experimental Data

The essence and shortcoming of turbulence modeling and simulation of atmospheric boundary/surface layers are discussed. The present approach rests on the extensively tested and widely used two-equation k-ε model to predict such flows. All features and constants of the standard version of the k-ε model as it is used for shear flows are retained here. This eliminates the requirement of rigorous experimental validation. However, the model with its set of boundary conditions features compatibility and realizability with the commonly reported stable, unstable and neutral atmospheric boundary/surface layer data. The paper presents also a comparison with experimental data and other models and the need for future research in this direction.

Identification Procedures

In this paper, a solution for the mathematical modeling and simulation of the technological process associated to a turbine – synchronous generator group, belonging to a small hydroelectric power plant. In order to determine the parameters of the treated technological process, some experimental identification procedures are applied. The experimental identification procedures are applied to the experimental data obtained from the real plant. The validity of the obtained mathematical model is proved through the comparison of the experimental data with the data obtained after the model simulation. The technological importance of having a valid mathematical model of the hydroelectric process consists in the possibility to study the plant behavior for different working regimes using the results of the model simulation and in the possibility of including the process in an automatic control structure.

This study aimed at the modeling and simulation of intermittent drying to be applied to highly deformable moist foods such as apples. Mass transport modeling considered two stages: the first at 95, 85 and 75ºC air temperatures, and the second at 60ºC. The shrinkage was correlated with the sample moisture and included in the model that was solved by the finite differences method. The first stage temperatures affected the water diffusivity in the second stage. This model was suitable for simulating the water profiles during the two-stage intermittent drying, showing an efficient fitting to the experimental data. Keywords: thermal intermittence; coefficient diffusion effective; shrinkage; apple drying.
