The ratio between the intensity of the mass transfer in gas and the heat transfer in liquid during the evaporative solution concentration has been studied. It was determined that the share of liquid resistance in the total resistance to enthalpy transfer increases in the temperature range from 30 to 50°C by almost 2 times, and reaches 40 %. The technique has been developed for the separate determination of the mass transfer coefficients in gas and heat transfer in liquid.<br>Досліджено співвідношення між інтенсивністю масопереносу в газі та передачею тепла в рідині під час концентрації випарно

The enthalpy (sensible and latent heat) exchange processes within the surface layers at an air-water interface have been examined in 15-m wind-wave tunnel at the University of Miami.

Desiccant-enhanced air conditioning equipment has exhibited both the capability to improve humidity control and the potential to save energy costs by lowering the latent energy requirement of the supply air stream. The resulting increasing popularity of desiccant-enhanced air conditioning systems has sparked new interest in the search for a better, more efficient desiccant material. The ultimate goal of this research was to develop a material that, when applied to an existing air-to-air heat exchanger, would achieve the necessary heat and mass transfer in a single process, thus transforming a

Electron transfer, ET, and proton-coupled electron transfer, PCET, reactions are central to biological reactions involving catalysis, energy conversion and energy storage. The movement of electrons and protons in either a sequential or concerted manner are coupled in a series of elementary reaction steps in respiration and photosynthesis to harvest and convert energy consumed in foodstuffs or by absorption of light into high energy chemi-cal bonds in the form of ATP. These electron transfer processes may be modulated by conformational dynamics within the protein matrix or at the protein-protei

This research is concerned with the development of a mathematical approach for energy and mass transport in solidification modelling involving a control volume (CV) technique and finite element method (FEM) and incorporating non-physical variables in its solution. The former technique is used to determine an equivalent capacitance to describe energy transport whilst the latter technique provides temperatures over the material domain. The numerical solution of the transport equations is achieved by the introduction of two concepts, i.e. weighted transport equations and non-physical variables. T

Methicillin-resistant Staphylococcus aureus (MRSA) are opportunistic commensal bacteria that are evolving to become increasingly resistant to antimicrobial agents. Resistance is due to acquisition of resistance genes encoded by mobile genetic elements (MGEs) but little is known about the gene transfer and conditions influencing this process in clinically important MRSA isolates. In this thesis I showed that populations of MRSA colonizing isolates vary phenotypically in antimicrobial resistance (AMR) and genotypically in MGE profiles.

To combat widespread infections caused by Staphylococcus aureus, mupirocin was introduced at the Veterans Affairs Medical Center, Mountain Home, Tennessee.

Results have shown that transfer of high-level mupirocin-resistance from S. aureus donors commonly occurs. However, transfer from naturally-occurring S. epidermidis donors was not attainable.

Antibiotic resistance (AR) is a public problem for human health and food safety. Globalization has contributed to create an intense connection among human and animal health and the environment, allowing bacteria and their genes to move among all these compartments, making a “one-health approach” necessary to counteract this phenomenon. Horizontal gene transfer (HGT), which contributes to AR determinants diffusion, is mediated by three main mechanisms: i) conjugation, ii) transduction, and ii) natural transformation. Several environments linked to the agri-food system are both sources of AR det

Progressive collapse is defined as the spread of an initial local failure of a critical load bearing structural element to the remaining structure, ultimately leading to the collapse of the entire building or of a large portion of it. After the partial collapse of the Ronan Point apartment tower in 1968, when a localised gas explosion ultimately led to the collapse of the whole corner of the building, progressive collapse firstly drew public attention due to its catastrophic consequences on human casualties and economic losses. Other recent collapse events, such as those of the Murrah Federal

Sebastian Zetterström, Master of Science in energy systems, Mälardalens University in Västerås. Abstract of Master’s thesis, submitted 16th of August. Evaluation of a suction pyrometer by heat and mass transfer methods. The aim of the thesis is to evaluate the cooling of a specific suction pyrometer which is designed by Jan Skvaril, doctorate at Mälardalens University. First part is explained how the balances and correlations are performed before being implemented in MATLAB, after this a ANSYS Fluent model is constructed and explained, which is used for the comparison of results. The cooling

Thermal contact resistance or, its reciprocal, thermal contact conductance is an important parameter in a wide range of thermal phenomena. It plays a significant role in heat transfer applications such as electronic packaging and nuclear reactors. This parameter also appears in fin-tube heat exchangers; however, it is often neglected in the performance calculations of heat exchangers. This thesis project explores the means by which the heat transfer performance of a finned tube heat exchanger may be enhanced. It includes experimental studies and finite element analysis investigating the effect

A previously undescribed tetracycline resistance gene, <I>tet</I>(W), was isolated by our group from the rumen anaerobe <I>Butyrivibrio fibrisolvens. tet</I>(W) is less than 65% homologous to <I>tet</I>(M) and in the <I>B. fibrisolvens </I>strain 1.230, is carried on a 50 kb mobile chromosomal element, Tn<I>B1230</I>, which is unrelated to known conjugative transposons. This thesis has identified a gene >99% homologous to <I>tet</I>(W) from two groups of human faecal bacteria, a low % G+C Gram Positive human colonic bacteria, Strain K10 and <I>Bifidobacterium longum</I>. In each isolate <I>tet

In the present study, a finite volume method is employed to modelthe advection-diffusion phenomenon during a pure substance meltingprocess. The exercise is limited to a benchmark problem consisting ofthe 2D melting from a vertical wall of a PCM driven by natural convectionin the melt. Numerical results, mainly the temporal evolutionof average Nusselt number at the hot wall and the average liquid fraction,are validated by available literature data and the effect of thermalinertia in the heat transfer is considered as well. Finally, motivatedby recent publications and the model presented here, p

This report details the development and validation of a model for the simulation of supported liquid membrane processes, as applied to the extraction of lanthanides. Supported liquid membranes are systems where two phases, usually aqueous, are separated by a third phase, typically organic, which acts as a membrane, in order to separate solutes from one phase to the other. The model employs an analytical solution to the diffusion equation for the organic phase and linear approximations of the resistances to mass transfer in the aqueous phase boundary layers. The goal of this model is to underli

This thesis investigates the cooling behaviour of polymers during the microinjection moulding process. The work included bespoke experimental mould design and manufacturing, material characterisation, infra-red temperature measurements, cooling analysis and cooling prediction using commercial simulation software. To measure surface temperature of the polymers, compounding of polypropylene and polystyrene with carbon black masterbatch was performed to make materials opaque for the IR camera. The effects of addition of carbon black masterbatch were analysed using differential scanning calorimetr

This research contributes to an understanding of Japanese Foreign Investment (JFDI) in Poland, by using a Variety of Capitalism approach and drawing on literature from employment relations. It examines firstly, the extent to which Japanese production and managerial institutions and practices can be transplanted to different economic and cultural environments; and secondly, the character of workers' response towards these practices, in the context of JFDI in Poland. It draws on primary data drawn from interviews conducted with the managers and workers in five firms in a Japanese electronics man
