title: Mad Diffraction Images For Yeast 5-Aminolevulinic Acid Dehydratase (Alad).

description: Selenomethionine multiwavelength anomalous dispersion (MAD) diffraction images for the original structure determination of 5-aminolevulinic acid dehydratase (ALAD) from yeast collected at the bending magnet beamline BM14, ESRF, Grenoble (25-27 Sept 1996). There are separate folders for the data from different wavelengths (l1 is the edge dataset, l4 is the edge inverse beam, l2 is the peak, l5 and l55 are the peak inverse beam (l55 is an overlapping continuation of l5 due to beam loss), l3 is the remote and l6 is the remote inverse beam). The seoa folder contains the selenium 'optimised anomalous' peak data. The images were collected with a Mar Research image plate and each folder has a file called 'mos.com' giving the data collection parameters for that run except for the exposure times which were 45 seconds per image for both l1 and l2, 55 seconds per image for the remote l3 and 120 seconds per image for the optimised anomalous collection (seoa). The latter dataset does not have a file listing the parameters which were: crystal-to-detector distance 275mm, delta-phi 1 degree, wavelength 0.9791 Angstroms, big-MAR format (note other datasets were collected in small-MAR format).

title: From lumped to full scale modeling approach: on the use of computational fluid dynamics to model heat and mass transfer processes in water cooled evaporator.

description: This paper reports on an extensive numerical investigation of a water cooled evaporator following a full scale modeling approach. A 3D CFD model of a water cooled evaporator was constructed to simulate the hydrodynamics and thermal fields of humid air and refrigerant (water) flow streams. The problem involves a conjugate heat transfer turbulent multi-phase flow situation where condensation on the outer surface of the evaporator coil was modeled following Fick’s law. The pressure and velocity coupling was resolved by the segregated SIMPLE-Consistent algorithm. Solutions were generated via a hybrid collocated unstructured finite volume method for wet and dry coil assumptions. Complex turbulent flow fields were obtained at different regions of the evaporator coil. Numerical predictions were then compared with available experimental data of similar coil construction for validation purposes. On the other hand, a lumped analytical model for dry heat transfer phenomena was developed and simulated for dry coil assumptions. The purpose of the lumped model is to show its limited predictive capabilities in capturing the detailed physics of the problem in contrast to the full CFD approach. Results have shown the need to tune the lumped model to fit with the more realistic situation modeled by the full scale approach. This paper concludes the fortuitous need to shift towards full scale modeling approaches in simulating industrial applications where lumped models, if not properly tuned, lack the ability to capture the physics of the defined problem.

title: Design of two-stage thermoacoustic Stirling engine coupled with push-pull linear alternator for waste heat recovery.

description: Thermoacoustics is suitable technology for recovering waste heat and generating electricity. In this paper, a novel thermoacoustic electricity generator using a push-pull linear alternator is proposed. It is aimed to recover part of the internal combustion engine exhaust waste heat and produce useful electricity. It consists of two half wave length identical stages and a linear alternator connected in between them. The physically identical stages produce identical wave halves with acoustic pressure out of phase. The availability of two points having the same pressure amplitude out of phase provides the opportunity to connect the linear alternator to two points in each stage to run the alternator in a "push and pull" mode. The proposed engine is able to produce more than 138.4W of electricity at thermal-to-electrical efficiency of 25.1% equivalent to a fraction of Carnot efficiency of 45.1% while using helium pressurized at 40 bar.

title: Investigation on the matching performance of a small cryogenic air turboexpander.

description: The matching performance of a turboexpander is essential for a small reverse Brayton air refrigerator, especially when it works under varied operation parameters. Generally, an appropriate brake pressure is required when the turboexpander works under different operation parameters. In this paper, the matching performance of a turboexpander supported by a bump journal foil bearing and a pressurized thrust gas bearing is studied. A centrifugal blower is used as a brake. The performance curve is analyzed through a numerical simulation using CFX. The matching calculations were carried out with different brake blowers under both room temperature and low temperature. A brake pressure feedback control is applied in the experimental study. A thermal performance of the refrigerator is tested. The results indicated that the appropriate brake blower and brake pressure facilitate the system thermal performance under both room and low temperature. The simulation agrees well with the experimental results.

title: Theoretical analysis of CO2 transcritical system with parallel compression for heat recovery and air conditioning in supermarkets.

description: This paper theoretically analyses a CO2 trans-critical booster system in which parallel compression, heat recovery and air conditioning are integrated. The performance of the system is studied in various running modes using flash gas by-pass (FGBP) or parallel compression (PC). These running modes include summer cases with/without air conditioning and winter case with heat recovery. The results show that parallel compression is more efficient than flash gas by-pass in summer cases; the increase in COPtot is up to 14% comparing the best cases for PC and FGBP. The increase in COPtot in winter heat recovery mode is marginal, less than 4-6% and hardly-feasible in practice. Comparing the AC function of the CO2 system with a conventional HFC air conditioning system, it has been found that CO2 system is more efficient in moderate ambient temperatures lower than 20-25°C. The CO2 system’s AC performance is less efficient than HFC solution in ambient temperatures higher than 25°C. To conclude, an integrated CO2 trans-critical booster system can to provide the entire supermarket’s refrigeration and air conditioning demands for cold-mild climates with comparable or higher energy efficiency than the HFC solutions.

title: Performance prediction of magnetocaloric heat pump with material layered active magnetic regenerator.

description: The function of the magnetocaloric heat pump with an active magnetic regenerator (AMR) cycle is based on a magnetocaloric effect (MCE). In the process of the AMR cycle, the range within which the magnetocaloric material (MCM) exhibits an MCE is narrow near its Curie point. Therefore, there is only a narrow temperature span in the case of an AMR with a single MCM. In order to solve this problem, an AMR system with material layers was used, based on the arrangement of a couple of MCMs in the regenerator. Given that only a limited number of studies exist on the magnetocaloric heat pump using a material-layered system, the influence of the MCM properties on this heat pump is still unclear. Therefore, the refrigeration capacity and the temperature span of the magnetocaloric heat pump using the material-layered system are numerically evaluated in this study in order to obtain guidance for the system design. These results are compared with those gotten extracted for the magnetocaloric heat pump of the single MCM.

title: Adsorption-based low temperature refrigeration using water-ethylene glycol mixtures.

description: Adsorption chilling with the working fluid water is environmentally friendly, but limited to cooling temperatures above 0°C. To expand the operational range of adsorption chillers below the freezing point of water, experiments have been conducted adding ethylene glycol to the evaporator as anti-freezing agent. According to vapour liquid equilibrium data ethylene glycol should remain in the evaporator. Thus, only water should serve as refrigerant. Experiments with cold production at 0°C demonstrate that the adsorption process still works if ethylene glycol is used as anti-freezing agent in the evaporator. Furthermore, measured ethylene glycol concentrations in condenser and evaporator confirm that almost pure water is used as refrigerant. Increasing ethylene glycol concentrations in the evaporator decreases the heat flows. This decrease is caused by reduced heat transfer properties of the ethylene glycol-water mixture. Better heat transfer properties can be achieved by using different evaporator designs allowing low temperature refrigeration in adsorption chillers.

title: Thermophysical properties of phase change emulsions prepared by D-phase emulsification method.

description: PCE (Phase Change Emulsion) is a mixture of an aqueous surfactant solution and fine particles of PCM (Phase Change Material) dispersed inside it. PCE is attracting attention as a novel thermal medium because it offers not only high-density thermal storage utilizing latent heat of the PCM but also easy heat transportation due to its high fluidity. In the present study, PCEs are prepared according to D-phase emulsification method and their properties are evaluated experimentally. Two different kinds of paraffin-PCMs, n-hexadecane and n-octadecane were dispersed inside the PCE and their mass fraction is varied as a parameter. It became clear that the PCEs show extremely similar particle size distributions regardless of the dispersed material or its mass fraction. In addition, viscosity of the PCE increases with increased PCM mass fraction in agreement with theoretical values. Furthermore, their heat of fusion and specific heat were evaluated by temperature history method.

title: Impact Of Us Brown Swiss Genetics On Milk Quality From Low-Input Herds In Switzerland: Interactions With Season

description: This study aimed to investigate the effect of, and interactions between, US Brown Swiss genetics and season on milk yield, basic composition and fatty acid profiles, from cows on low-input farms in Switzerland. Milk samples (n=1,976) were collected from 1,220 crossbreed cows with differing proportions of BS, Braunvieh and Original Braunvieh genetics on 40 farms during winter-indoor and summer-grazing seasons. Cows with more Brown Swiss genetics produced more milk in winter but not in summer, possibly because of underfeeding high-yielding cows on low-input pasture-based diets. Cows with more Original Braunvieh genetics produced milk with higher concentrations of (i) nutritionally desirable <em>trans</em>-9 palmitoleic, eicosapentaenoic and docosapentaenoic acids, throughout the year, and (ii) vaccenic and α-linolenic acids, total omega-3 fatty acids concentrations and a higher omega-3/omega-6 ratio during the summer-grazing period only. This suggests that overall milk quality could be improved by re-focusing breeding strategies on the cows’ ability to respond to local dietary environments and seasonal changes in feeding regimes.

title: Numerical simulation of nitrogen condensation flow in a cryogenic nozzle.

description: 2-D numerical simulations on the nitrogen expansion flow with spontaneous condensation in a nozzle were conducted based on the equilibrium model and the non-equilibrium model respectively. In the equilibrium model, the mass transfer between the liquid and vapor is determined by the saturation enthalpies of the liquid and vapor phases. The pressure distribution of the nozzle could be influenced slightly by the condensation process. In the non-equilibrium model, the classical nucleation model is used for the droplets formation. The flow is heated by the latent heat and consequently the decrease of pressure and the increase of Mach number are delayed. Meanwhile, due to the requirement of a certain supercooling level, the condensation onset point is pushed away from the nozzle inlet, and the nozzle outlet wetness fraction becomes smaller. Then, the influence of the nozzle inlet temperature and inlet pressure on gas supercooling, nucleation rate and wetness are analyzed.

title: High temperature heat pumps for seasonal thermal energy storage and district heating systems.

description: R245fa was selected to operate with a the working fluid for a seasonal thermal energy storage (STES) heat pump whose role was to upgrade the temperature of the heat when it was insufficient to heat a hospital administration building near Warsaw, Poland. The selection of R245fa was based on a series of theoretical and laboratory tests indicating its superior performance when operating with the higher evaporator conditions encountered when working with a STES. High coefficients of performance are presented and the challenges of operating a heat pump with a STES are discussed.

title: Design a two-stage looped-tube thermoacoustic cooler for thermal management of enclosures.

description: Design options for a travelling wave thermoacoustic refrigerator have been considered with the view of using it for thermal management of various enclosures/compartments. Acoustic drivers such as loudspeakers or linear motors are essential for such thermoacoustic devices as they enable the conversion of electrical to acoustic power. The theoretical knowledge of how to couple an acoustic driver to thermoacoustic refrigerators or engines efficiently has been illustrated by studying the performance of an acoustic driver when connected to selected types of acoustic networks using DeltaEC. A final design comprising a two-stage refrigerator (two thermoacoustic cores in series) driven by two acoustic drivers (model 1S132, available from Q-Drive) has been presented together with the discussion regarding acoustic matching. The overall efficiency (electricity to cooling power) has reached nearly 125% when the temperature difference between the cold and ambient heat exchanger is 25 K to produce 447 W of cooling power.

title: Melting behavior and heat transfer characteristics of water-insoluble material immersed in water.

description: This paper presents the melting behavior and heat transfer characteristics of a water-insoluble material immersed in water. N-hexadecane, popularly used as a phase change material, is adopted as a water-insoluble material. A rectangular n-hexadecane solid is placed vertically in the water. The melting behavior of n-hexadecane and its melting rate are then observed under a variety of water temperature conditions in the test vessel. An evaluation of the melting behavior and the local heat transfer coefficient indicates that the ambient water flow along the vertical n-hexadecane block enhances heat transfer at the upper side of the block as the ambient water temperature becomes lower. The upward flow of the melting liquid prevents the melting heat transfer at the upper part of the block as the ambient water temperature becomes higher. The variation of the shape of the top part of the block then changed and the heat transfer coefficient barely decreased when Polyoxyethylene Sorbitan Monooleate (Tween 80) was added in the water.

title: Heat pump operating with NH3 or CO2 - A comparative study.

description: The paper deals with a dual purpose system that operates as heat pump and refrigerator for heating and air conditioning. Due to the large temperature differences between the two costumers (one supplied with heat and the other with refrigeration) the system operates in two stages. A comparative study of the conduct of different schematics of the system when operating with NH3 or CO2 was performed. The exergetic analysis was used to point out which are the causes of inefficiencies when operating with each one of the two natural refrigerants. Observing that CO2 causes lower exergy destructions when functioning at low temperatures and also that CO2 can be used directly in the cooling chamber (while NH3 needs an intermediary agent) a new schematic is proposed operating in cascade with NH3 in the upper stage and CO2 in the lower one. The efficiency of the cascade system is similar to the two-stage NH3 system but in the first case the installation takes advantage of the fact that CO2 in the cold space is harmless in case of accidentally leakages.

title: Characterization of inexpensive stack materials for use in standing wave thermoacoustic refrigerators.

description: Stacks are some of the vital parts of standing wave thermoacoustic refrigerators where the energy transfer occurs thanks to a thermoacoustic effect. There are two main issues regarding stacks. Firstly, stacks might be costly due to costs of materials and secondly, their fabrication costs may be prohibitive due to the involved/impractical assembly processes. One of the solutions to these issues could be stacks made of some "random" materials such as stainless steel wool or copper scourers which are low-cost, widely available and easy to shape to take the form of a stack. Moreover, parallel plate stacks can be manually made by using regular and inexpensive materials such as Mylar sheets. Some chosen stack materials such as mentioned above have been used and studied by carrying out measurements on a standing wave thermoacoustic refrigerator working in a half-wavelength mode. This work aims to investigate the thermal performance of such inexpensive stack materials. It is believed that this investigation will be beneficial for developing low-cost thermoacoustic refrigerators for both domestic and commercial applications.

title: Effects of Alpha and Beta Emitters in Lung
title: Link to data and details in ERA

description: Purpose: To determine the relative biological effectiveness (RBE) of inhaled, insoluble alpha- and beta-emitting radionuclides with respect to late carcinogenic effects.

Status: 1990 - 1994

Treatment: Single nose-only exposure to fused aluminosilicate particles (FAP) labelled with Cm-242 (alpha-emitter) or Ca-45 (beta-emitter), AMAD about 1,6 μm, 1.2-1.3 sigma g.

Dosimetry: Initial alveolar deposit (IAD and radiochemical analysis to determine Cm-242 or Ca-45 content of lungs from mice killed at 1, 7, 28, 84, 196, 308, 504, and 672 days post exposure. Trapezoidal method used to calculate average radiation dose to lungs.

Endpoints: Life-span study with sacrifice of moribund animals. Necropsy observation and histopathology of all macroscopically obvious abnormalities. Lungs cleared to determine the absolute number of lung lesions.

Animal: Female CBA/Ca mice 10 weeks of age at time of exposure

Results: The survival studies do not indicate differences between the treated and non-treated groups. Macroscopic studies on the lung suggest, however, that lung tumours in controls begin to appear at an age of about 700 days and increase steadily to about 30% towards the end of the life. Following exposure to Cm-242 or Ca-45 labelled FAPs the latency period appeared reduced and the incidence increased. There was, as yet, no indication that the RBE could be 20 for alpha particles. The histopathological evaluation is now under way to confirm the these data.

title: Effects of Radiation Quality on the Induction of Leukaemia in CBA/CA Mice
title: Link to data and details in ERA

description: Purpose: To study the induction of myeloid leukaemias in mice following the administration of fused aluminosilicate particles (FAP) incorporating aloha- and beta-emitting radionuclides. This information will be used to estimate the most appropriate value for the quality factor of high LET radiations with respect to radiation-induced haemopoietic malignancies.

Status: 1991 - 1995

Treatment: Single intravenous administration of fused aluminosilicate particles (FAP) labelled with Cm-242 (alpha-emitter) or Ca-45 (beta-emitter). Actual diameter of FAP =1.90 ± 0.85 μm.

Dosimetry: Radiochemical analysis to determine Cm-242 or Ca-45 content of tissues from mice killed at 1, 7, 14, 30, 76, 150, 300 and 601 days post injection. Trapezoidal method used to calculate average radiation dose to tissues. Also autoradiographic analysis of liver, spleen and bone marrow to determine microdistribution of FAP.

Endpoints: Life-span study with sacrifice of moribund animals. Necropsy observation and histopathology of all macroscopically obvious abnormalities. Also full haematology for all animals killed in extremis

Animal: Female CBA/Ca mice 10 weeks of age (approximately 20 g) at time of exposure

Results: Following injection with the highest levels of Cm-242 or Ca-45 FAPs, survival was reduced by about 4 and 3 months respectively from the 900 days lifespan of controls . Liver tumours were observed in about 10% of the controls but in about 20% of Cm242-injected mice. Subcutaneous masses thought to arise from benign enlargement of subcutaneous lymph nodes were the most common (30%) abnormality in controls and contributed to morbidity and mortality of the animals. However, the incidence of these masses was reduced in animals injected with the highest levels of Cm-242 or Ca-45 FAPs. On the contrary the incidence of animals with enlargement of multiple lymph nodes, splenomegaly and accumulation of fluid in abdomen and thoracic cavity, signs characteristic of leukaemias, increased from low levels in controls to 11% following injection of radio-labelled FAPs. The histopathological evaluation is now under way.
