To assess the antimicrobial effect of a commercial steam-vacuuming system newly implemented after slaughtering, 105 cattle carcasses were examined for total viable counts (TVC) at four different areas. Before steam vacuuming, mean TVC of the excision samples were comparable at the perineal area and brisket (3.0-3.1 log CFU cm-2) or the hind leg and shoulder (2.6-2.7 log CFU cm-2). Steam vacuumi...

Alkaline wet oxidation and steam explosion pretreatments of sugarcane bagasse were compared with regard to biomass fractionation, formation of by-products, and enzymatic convertibility of the pretreated material. Wet oxidation led to the solubilisation of 82% of xylan and 50% of lignin, and to a two-fold increase of cellulose content in the pretreated solids, while steam explosion solubilised o...

The goal of this research has been to compare steamand air-water transport through fractured media and gain better understanding of the behaviors of relative permeability in fractures. Airwater (or nitrogen-water) relative permeabilities are often used for geothermal reservoir simulations while steam-water relative permeabilities in fractures are rarely measured owing to difficulties and comple...

The composition of the essential oils of Teucrium chamaedrys L. belongs to the family Lamiaceae, It is growing wild in the margin of mountainous roads of arid and cold climate of north Iran. In this research, essential oils of T. chamaedrys, extracted and measured at the different location by different methods of distillationand then were analyzed by GC and GC/MS. Investigation and comparison o...

This paper describes the feasibility study of an artificial neural network for signal prediction. The purpose of signal prediction is to estimate the value of undetected next time step signal. As the prediction method, based on the idea of auto regression, a few previous signals are inputs to the artificial neural network and the signal value of next time step is estimated with the outputs of t...

Stream control has recently attracted attentions in the research of MIMO wireless networks as a potential way to improve network capacity. However, inappropriate use of stream control may significantly degrade network capacity as well. In this paper, we provide the first formal study on stream control scheduling in MIMO wireless mesh networks. We derive the theoretical upper bound on network ca...

Abstract: The paper presents the research results related to control of the steam boiler parameters: drum level, furnace pressure and steam pressure. It was developed the mathematical model of the water-steam system and furnace part of the boiler. Also, the paper presents the algorithm for real time detection of model parameter variations. In this context a correction method, validate through s...

Starting with a classical process for producing methanol using the reforming and synthesis steps, a combined approach applying simulation models and a new synthesis strategy, named Effect Modelling and Optimisation (EMO), has been used to optimise the energy efficiency of the process. The method allows to identify different ways of improving the energy efficiency of the process. The modificatio...

The results of an investigation evaluating the feasibility of using optical measurements for the real-time monitoring of fluid properties in geothermal process streams is described. The measurements exploit new technologies that have been developed for the telecommunications industry and include new solid state laser devices, large-bandwidth, high-sensitivity detectors and low loss optical fibe...
