Fourier-Transform Infrared Spectroscopic Imaging Of Prostate Histopathology, Daniel Celestino Fernandez May 2003

Fourier-Transform Infrared Spectroscopic Imaging Of Prostate Histopathology, Daniel Celestino Fernandez

USF Tampa Graduate Theses and Dissertations

Vibrational spectroscopic imaging techniques have emerged as powerful methods of obtaining sensitive spatially resolved molecular information from microscopic samples. The data obtained from such techniques reflect the intrinsic molecular chemistry of the sample and in particular yield a wealth of information regarding functional groups which comprise the majority of important molecules found in cells and tissue. These spectroscopic imaging techniques also have the advantage of acquisition of large numbers of spectral measurements which allow statistical analysis of spectral features which are characteristic of the normal histological state as well as different pathologic disease states. Databases of large numbers of samples …

Longevity Of A Woodhouse's Toad, Richard M. Engeman, Melvin A. Engeman May 2003

Longevity Of A Woodhouse's Toad, Richard M. Engeman, Melvin A. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

We follow up a report on a male Woodhouse's toad (Bufo woodhousii) that had been observed since 1978 (Engeman RM, Engeman EM. 1996. Longevity of Woodhouse's toad in Colorado. Northwestern Naturalist 77:23). The toad had found its way into, and remained in, a basement window-well of a brick home in an unincorporated western suburb of Denver, Colorado. This property has recently changed hands, and access for future monitoring of the toad's survival is uncertain. Thus, we report its longevity as of 2002.

Physical Water Treatment For The Mitigation Of Mineral Fouling In Cooling-Tower Water Applications, Young I. Cho, Sunghyuk Lee, Wontae Kim, Sangho Suh

Heat Exchanger Fouling and Cleaning: Fundamentals and Applications

The physical water treatment (PWT) device is defined as a non-chemical method of water treatment utilized for the purpose of scale prevention or mitigation. Three different PWT devices, including permanent magnets, solenoid coil device, and high-voltage electrode, were used under various operating conditions. The present study proposed a bulk precipitation as the mechanism of the PWT and conducted a number of experimental tests to evaluate the performance of the PWT. The results of fouling resistances obtained in a heat transfer test section clearly demonstrated the benefit of the PWT when the PWT device was configured at an optimum condition. The …

Direct Measurement Of The Forces Required To Disrupt And Remove Fouling Deposits, W. Liu, Z. Zhang, G. K. Christian, P. J. Fryer May 2003

Direct Measurement Of The Forces Required To Disrupt And Remove Fouling Deposits, W. Liu, Z. Zhang, G. K. Christian, P. J. Fryer

Heat Exchanger Fouling and Cleaning: Fundamentals and Applications

In cleaning, the force required to disrupt the deposit and remove it from the surface tends to be inferred from flow data, rather than being known directly. A novel micromanipulation technique has been developed to measure directly the adhesive strength of food fouling deposits on a stainless steel surface. A T-shaped stainless steel probe pulls fouling deposits away from the surface to which they are attached. The apparent adhesive strength between the fouling deposits and the substrate can be measured as the work required to remove the deposits per unit area from the substrate. Tomato pastes and whey proteins have …

Fouling Of Some Canadian Crude Oils, M. Srinivasan , A. P. Watkinson May 2003

Fouling Of Some Canadian Crude Oils, M. Srinivasan , A. P. Watkinson

Heat Exchanger Fouling and Cleaning: Fundamentals and Applications

A thermal fouling study was undertaken using three sour Canadian crude oils. Experiments were carried out in a re-circulation fouling loop, equipped with an annular (HTRI) electrically heated probe. Fluids at pressures of about 1000-1340 kPa under a nitrogen atmosphere were re-circulated at a velocity of 0.75 m/s for periods of 48 hours, and the decline in heat transfer coefficient followed under conditions of constant heat flux. Bulk temperatures were varied over the range 200-285°C, and initial surface temperatures from 300 to 380°C. Heat fluxes were in the range of 265-485 kW/m2.

Challenges In Cleaning: Recent Developments And Future Prospects, D. I. Wilson May 2003

Challenges In Cleaning: Recent Developments And Future Prospects, D. I. Wilson

Heat Exchanger Fouling and Cleaning: Fundamentals and Applications

There is considerable scope for optimisation of processes subject to fouling by effective management of cleaning. The cleaning cycle starts with the (often-complex) material generated during the fouling cycle. The nature of the deposit determines the most appropriate cleaning method, which can often be optimised significantly via knowledge of the key mechanisms involved in deposit removal. Links between deposit ageing and cleanability need to be established and quantified. There is a wide range of cleaning methods available, and attention is focused here on cleaning-in-place (CIP) techniques. Modern instrumentation allows cleaning (and deposit materials behaviour) to be probed to greater degree …

Fouling Characteristics Of A Light Australian Crude Oil, Zaid S. Saleh, R. Sheikholeslami, A. P. Watkinson May 2003

Fouling Characteristics Of A Light Australian Crude Oil, Zaid S. Saleh, R. Sheikholeslami, A. P. Watkinson

Heat Exchanger Fouling and Cleaning: Fundamentals and Applications

Australian crude oils, which generally contain little asphaltenes, nevertheless give rise to fouling in refinery pre-heat trains. In this research, fouling of a series of such crude oils and their blends is being assessed. The present work focuses on thermal fouling resulting from heating Gippsland crude oil at moderate temperatures. The oil is maintained under nitrogen at a pressure of 379 kPa, and re-circulated at bulk temperatures of 80-120°C through an electrically heated annular probe at velocities in the range 0.25 to 0.65 m/s with surface temperatures from 180-260°C. Experiments are run for periods up to 90 hours at constant …

Study Of Whey Protein Adsorption Under Turbulent Flow , Olga Santos, Tommy Nylander, Gerhard Rizzo , Hans Müller-Steinhagen, Christian Trägårdh, Marie Paulsson

Heat Exchanger Fouling and Cleaning: Fundamentals and Applications

Reducing fouling in heat exchangers during treatment of milk products is one of the great challenges in the dairy industry. One approach to mitigate fouling is to alter the surface characteristics of the heat exchangers making them less prone to protein adsorption. On this background the European project MODSTEEL was established to study the use of new modified stainless steel surfaces to control fouling of milk components. This part of the project focuses on the adsorption of b-lactoglobulin (b-Lg) from a whey protein solution on unmodified and modified 316 2R stainless steel surfaces by in situ ellipsometry under well-defined flow …

The Practical Application And Innovation Of Cleaning Technology For Heat Exchangers, George E. Saxon Jr., Richard E. Putman May 2003

The Practical Application And Innovation Of Cleaning Technology For Heat Exchangers, George E. Saxon Jr., Richard E. Putman

Heat Exchanger Fouling and Cleaning: Fundamentals and Applications

The fouling of heat exchangers not only has a negative impact on heat transfer efficiency but also may restrict the output or production capacity of the facility. Given the cooling medium and the process, heat exchangers may be lightly fouled with organic deposits or may be severely blocked from hardened process chemicals. The probability of success in cleaning the heat exchanger is dependent on the selection of the appropriate cleaning technology under the specific fouling conditions. Early identification of fouling characteristics and a fundamental knowledge of cleaning system capabilities are essential in determining the most effective cleaning technology and the …

Fouling Mitigation Using Helixchanger Heat Exchangers, Bashir I. Master, Krishnan S. Chunangad, Venkateswaran Pushpanathan May 2003

Fouling Mitigation Using Helixchanger Heat Exchangers, Bashir I. Master, Krishnan S. Chunangad, Venkateswaran Pushpanathan

Heat Exchanger Fouling and Cleaning: Fundamentals and Applications

One of the major indeterminates in the design as well as operation of heat exchangers is the rate of fouling a select heat exchanger geometry would exhibit over the operation cycles. Gradual deterioration of heat exchanger performance due to the accumulation of fouling film on the heat transfer surface is often accounted for in the form of a fouling resistance, or commonly known as the fouling factor, while determining the heat transfer surface required for a specific heat duty. More often, the fouling mechanism responsible for the deterioration of heat exchanger performance is flow-velocity dependent. Maldistribution of flow, wakes and …

Comparison Of Crude Oil Fouling Using Two Different Probes, A. P. Watkinson May 2003

Comparison Of Crude Oil Fouling Using Two Different Probes, A. P. Watkinson

Heat Exchanger Fouling and Cleaning: Fundamentals and Applications

A variety of different fouling rigs, each with its own advantages and disadvantages is available to assess crude oil fouling. In this research, fouling of three crude oils are compared, using two electrically heated annular probes with strikingly different modes of operation. The Hot Liquid Process Simulator (HLPS) was operated in single-pass mode, under creeping flow conditions for time durations of a few hours at constant surface temperature. The Portable Fouling Research Unit (PFRU) was operated at velocities a factor of 250 higher, and followed the fouling process over two or more days at constant heat flux, using re-circulation of …

Improvements And New Developments In Self-Cleaning Heat Transfer Leading To New Applications , Dick G. Klaren May 2003

Improvements And New Developments In Self-Cleaning Heat Transfer Leading To New Applications , Dick G. Klaren

Heat Exchanger Fouling and Cleaning: Fundamentals and Applications

Improvements in the design have made the fluidized bed heat exchanger better suitable for the revamp of existing vertical severely fouling heat exchangers in evaporators, crystallizers and reboilers into a self-cleaning configuration. Highly viscous non-Newtonian slurries used in mineral processing can benefit from the fluidized bed heat exchanger not only due to its self-cleaning performance, but also as a result of the shear-thinning action of the fluidized particles which dramatically lowers the viscosity of the slurry. New developments have created the possibility to design compact self-cleaning fluidized bed heat exchangers which can compete with plate and frame exchangers.
