title: Udvikling og sundhed hos børn født af ufrugtbare forældre - Infertilitet, fertilitetsbehandling og børns mixed-håndethed, 2008
title: Development and health of children born of infertile couples - Infertility, infertility treatment and mixedhandedness in children, 2008

description: Formålet med undersøgelsen er at finde sammenhængen mellem fertilitet eller infertilitetsbehandlinger med en stigning i risikoen for mixedhåndethed hos børn. Forhåndsantagelsen er, at mixedhånedethed kan være forbundet med en skade i barnets hjerne som følge af fertilitetsbehandlingen.
            Data udspringer fra "Bedre Sundhed for Mor og Barn" undersøgelsen i Aalborg-Odense i perioden 1984-1987 (N=7728), Aarhus i 1990-1992 (N=5720) og den nationale undersøgelse i 1996-2002 (N=29486).  Data om "Time to Pregnancy" (TTP) og infertilitetbehandling er indsamlet under moderens gradivitet. Data om håndethed er indsamlet ved hjælp af et follow up spørgeskema, da børnene var 7 år gamle. Børnene, som blev registreret som mixedhåndet udgør de børn, hvis mødre oplyste, at børnene var i stand til at bruge begge deres hænder lige godt.
            Resultatet af undersøgelsen viser, at børn født som følge af fertilitetsbehandling har større sandsynlighed for at blive mixedhåndede i forhold til børn, der er født af fertile par med TTP under 12 måneder.

title: Experimental study on thermal stress of cryogenic tank during different cool down process.

description: An experimental study is performed to investigate the transient thermal stress distribution of an aluminium alloy tank during cryogenic fluid filling processes. Three different filling procedures are adopted with liquid nitrogen being fed into the tank from the top axial nozzle, the bottom axial nozzle, and the top lateral sprayer, respectively. The transient temperatures and thermal strains are measured, and the local thermal stresses are calculated. The results indicate that fluid filling from top axial nozzle leads to the most uniform temperature distribution and the lowest transient thermal stress in the tank wall. Filling from bottom axial nozzle produces similar but much steeper cooling curves and higher transient thermal stresses. However, filling from top lateral sprayer generates a quite different temperature distribution and meanwhile, the highest level of thermal stress. Moreover, the cooling curves become more uneven as the feeding rate increases, resulting in higher transient thermal stresses.

title: Low-temperature natural helium separation processes for obtaining 3Helium isotope.

description: The problem of 3He shortage can be solved by cryogenic means using commodity helium, which is a natural mixture of 4He-3He isotopes. For the preliminary enrichment superfluid filtration through a coal filter was analyzed. Rectification and sorbtion methods were suggested as final stages for 3He enrichment. Rational process parameters as: concentration, temperature, enrichment ratio, for all adjacent technological stages are given. Experimental rectification data for low initial 3He concentration were obtained and the new sample ejection and mass-spectrometric methodology was created.

title: Understanding the physical phenomena that occur inside heat exchangers for liquefaction of hydrogen.

description: Liquid hydrogen is an attractive solution for long-range distribution. The largest barriers for implementing large-scale hydrogen liquefaction plants are currently their high energy consumption and cost. The heat exchangers are among the most important equipment in these plants. It has been shown that it may be beneficial to use a mixture of helium-neon ("Nelium") as refrigerant in the cryogenic cooling cycle, because this gives the possibility to utilize highly efficient turbocompressor equipment. In this work, we discuss the physical phenomena that are expected to occur inside cryogenic heat exchangers if Nelium is used as refrigerant for low temperature cooling and liquefaction of hydrogen. We present a detailed heat exchanger model for a simple heat exchanger geometry and study phenomena such as nonequilibrium ortho-para conversion, possible solid-formation of neon and boiling/condensation of Nelium at the lowest temperatures. We elaborate how the physical phenomena can be exploited in the design of more energy- and spaceefficient heat exchanger equipment for hydrogen liquefaction processes.

title: Numerical modeling of porous nozzles for regenerator of Stirling cryocooler.

description: A microcryogenic gas machine or microcryocooler is an important element of satellite navigation and communication systems. The main criterion of a cryocooler reliability is uptime at a given temperature level and a fixed value of the cooling capacity. The evaluation of a cryocooler uptime at the design stage by numerical analysis methods and taking into account the impact of various factors, including structural factors, at this time is an actual and difficult task. To solve this problem authors proposed to use the multivariate thermo gas dynamical analysis (MVTGA), the main principle of which is an integration of experience of experimental research and numerical simulation. The MVTGA has been developed by the authors of the paper, and the results of its application to analyze the microcooler design and thermodynamical processes in the microcooler regenerator are presented for the first time in this paper. The paper cites an example of application of MVTGA to analyze assembly units of a cryocooler as well as a mathematical 3D modeling of the structure and hydrodynamics of a porous regenerator as a main unit, accumulating risks. The paper also compares the results of a numerical study of the dependence of the hydraulic resistance of the simulated regenerator on the Reynolds number with the results of the calculation using correlation dependences of foreigner researchers.

title: Cryogenic infrastructure for the serial magnet test facility for FAIR.

description: In order to test the fast-ramped superconducting magnets for FAIR (Facility for Antiproton and Ion Research), a cryogenic test facility was designed, constructed, installed and brought into operation at GSI. The overall capacity of the cryo plant is about 1.5 kW @ 4.4 K equivalent and can be distributed to four test benches individually. In total 108 dipoles for the SIS100 will be tested at cold. The capacity of the cryogenic system is designed in order to simultaneously cool down one magnet while the other one is operated at cold state for the measurements. The other two test benches serve for warming up and for magnet exchange, respectively. Like this, one magnet per week can be tested. Beyond the dipoles, the high flexibility of the setup allows also the testing of other FAIR magnets, like the SIS100 quadrupole modules or the operation of a string configuration. The design of the cryogenic infrastructure, including an advanced feed box and magnet support system, will be presented. Operating experience from the first 8000 h of operating and serving different tests and an overview of the upcoming serial test time schedule will be given.

title: Study on propagation of temperature disturbance in indirect-drive inertial confinement cryogenic target system.

description: Sufficiently smooth ice layer inside the capsule is required for indirect-drive inertial confinement cryogenic target to achieve ignition, and this is considered to be affected by the thermal gradients around the outer surface of fuel capsule. A numerical investigation was conducted to examine the relation between the temperature disturbance on the cooling wall and the temperature distribution around the capsule surface, and was mostly concerned with periodic disturbance of cooling wall temperature. The effects of disturbance waveform such as sine, square and triangle, the disturbance frequency as well as the hohlraum gas composition are all investigated. The proposed numerical model is verified by a simplified cryogenic target, and the calculated temperature distribution around the capsule is in good agreement with the experimental data. The results indicate that amplitude attenuation is significant when the periodic disturbance propagates from the cooling wall to the hohlraum and to the capsule surface. For the three waveforms investigated in the present study, higher frequency results in larger attenuation of the disturbance amplitude. Square waveform temperature disturbance propagates faster and is more difficult to be attenuated when compared with sine form disturbance. The temperature fields inside the hohlraum and outside the capsule also demonstrate a dependence on the filling gas composition when the cooling wall temperature fluctuates, and higher proportion of H2 in the He-H2 mixture helps to suppress the propagation of disturbance.

title: An experimental study on the working characteristics of a methane-charged cryogenic loop heat pipe.

description: Methane-charged cryogenic loop heat pipe can realize efficient cryogenic heat transport at the temperature range of 90-190 K, which exhibits great application potential in the thermal control of future space infrared exploration system. In this work, an extensive experimental study on the supercritical startup and heat transport characteristics of a methane-charged cryogenic loop heat pipe integrated with a pulse tube cryocooler was conducted, where the effects of the auxiliary heat load applied to the secondary evaporator and was investigated. Experimental results showed that the CLHP could successfully realize the supercritical startup with an auxiliary heat load of 1.5 W. The CLHP could reach a heat transport capability of 7.5W over a distance of 0.6m corresponding to an optimum charged pressure of the working fluid. And there exists a minimum auxiliary heat load for the cryogenic loop heat pipe with primary heat load of 1W at some charged pressure. Furthermore, the mechanisms responsible for these phenomena mentioned above have been analysed and discussed qualitatively, providing a better understanding from the theoretical aspect.

title: Drastic increase of efficiency of induction-dynamic devices by using cryogenic cooling: experimental evidence.

description: A mathematical model of thermal processes, which describes different boiling regimes of cooling of the active elements of induction-dynamic devices (IDD) by liquid nitrogen, is developed. On the experimental vertically pitching copper armature IDD setup is found that presence of the ferromagnetic core increases the toss height by 2.1 times at room temperature, and under cooling with liquid nitrogen due to these elements - increases only by 1.3 times. Due to the cryogenic cooling height tossing an armature increases to 10.7 times in the absence of the core, and to 6.8 times in the presence of the core. With the simultaneous use the ferromagnetic core and cryogenic cooling toss height increases of 14.5 times. The results of experimental investigations up to 10 % are consistent with the calculated results. On the basis conducted researches proposed design scheme of IDD, intended for the shock treatment of technological equipment from viscous waste products.

title: Role of the superconductivity in radiative heat transfer.

description: The absorption and emission of thermal radiation by metals is related to their electrical properties that are influenced by impurities, defects and temperature. We show by some examples of measurements on common metals how different can be the thermal radiative properties. When the heat is transferred across a microscopic vacuum gap in the near field regime, it is possible to achieve a step- like change of the heat transfer based on a superconducting transition. An interesting feature of this effect is the nonlinear thermal conductivity effecting a change of the sign of the differential thermal conductivity across the vacuum gap.

title: Boil-off prevention and thermal modelling of LNG fuelling stations.

description: During Liquefied Natural Gas/Compressed Natural Gas from LNG (LNG/LCNG) station operation, boil-off gas (BoG) can be generated from different processes, like heat leak to the storage tank, cooling piping before fuelling, vapour return from LNG vehicles back to storage tank, evaporation of LNG, which was trapped in piping after fuelling process, etc. For modelling pressure dynamics in vacuum insulated storage tanks that are part of LNG fuelling stations, Heat-Management Program "Zero-loss" was developed. The program can be used for prediction of the pressure behaviour of the LNG storage tank that collects all the vapour inputs from operation of the station. The program can indicate optimal regimes of station operation, recommended frequency of vehicle fuelling, loading of the station, so that LNG venting is prevented or additional equipment for liquidation of BoG is not
needed. Heat-Management Program “Zero-loss” gives possibility to fill input process data, the station construction and features, and obtain the result as a graph of pressure dynamics in time as a function of frequency of fuelling. If station works in operation mode, when pressure growth in storage tank is unavoidable due to low frequency of fuelling, several types of boil-off gas handling equipment can be applied for prevention of venting of gas and, consequently, loss of LNG.

title: Exergy-based methods for air separation.

description: Air separation by cryogenic distillation has been used for over 100 years as an industrial process for producing pure nitrogen, oxygen as well as argon, helium and other noble gases. Different configurations and sizes of air separation plants lead to different ranges of gaseous and liquid products and different purity, which depend on the potential consumer and the application. Air separation processes are energy and cost intensive. 
In this paper, the exergetic, economic, and exergoeconomic analyses are discussed briefly, while attention is given to the LCA and the exergoenvironmental analysis as well as to exergy-risk-hazard analysis. The exergy-based methods are demonstrated using two configurations of an air separation plant. The results obtained from the exergetic analysis show that the overall exergetic efficiencies are approximately 35 % and 59 % for air separation plants with and without a nitrogen liquefaction block, respectively.

title: New cryogenic processes implemented for 3γ medical imaging with liquid xenon.

description: Our researches are geared towards a new low activity functional imaging technique named “3γ medical imaging” which requires a liquid xenon Compton camera. A specific detector, XEMIS2, has been developed and optimized for that purpose. The XEMIS2 camera is held in a cryostat connected to a purification circuit and a cryogenic tank called ReStoX. ReStoX is in charge of the xenon boil-off driving, the detector filling with liquid xenon at controlled pressure and temperature (1.2 bara at 168 K), the xenon recovering and storage. Our first studies have validated the ReStoX’s thermal behaviour and its ability to stabilize the pressure. We deduced a total heat losses reaching 17 W, a warm up duration close to 7 months and its clear ability to maintain a constant pressure (around 1 mbar mean fluctuation between peaks). Now we are ready to connect it to the cryostat.

title: The Gersemi vertical cryostat at FREIA.

description: “Gersemi”, a vertical cryostat to test superconducting magnets and radio-frequency cavities at liquid helium temperatures, will be installed at FREIA Laboratory at Uppsala University, Sweden. With three independent inserts, the same cryostat can be used to test different superconducting equipment at low power: a “vacuum” insert for cavities equipped with a helium vessel, a “bath” insert for cavities (and other equipment) without a helium vessel and a “lambda-plate” insert for magnet testing. Each insert has been designed to be as versatile as possible, making the available space inside the cryostat the main constraint for equipment testing. The cryostat will have an internal diameter of 1.1 m and 4.7 m total height. For magnet testing, “Gersemi” will be able to handle superconducting magnets with a stored energy up to 340 kJ. A valve box to direct the cryogens, a reheater for warming up the output gases and a control system complete the setup. "Gersemi" vertical cryostat is connected to a helium liquefier and recovery system, and in parallel to an existing horizontal cryostat for testing superconducting equipment already operational at FREIA Laboratory.

title: Cryogenic CO2 condensation and membrane separation of syngas for large-scale LH2 production.

description: Liquid hydrogen (LH2) has the potential to become a global energy commodity analogous to liquefied natural gas (LNG) in the future. This will require LH2 production capacities of similar scale as for large-scale LNG plants. Natural gas is an attractive energy source for production of carbon-neutral LH2. This production will require efficient CO2 capture and storage (CCS) combined with hydrogen purification. This work presents an advanced technology combination for large-scale hydrogen production with CCS intended for subsequent liquefaction and ship transport. Pure hydrogen for liquefaction is produced by exposing shifted syngas to a palladium membrane unit. The CO2-rich retentate is dehydrated and separated in a cryogenic condensation unit. The decarbonised, hydrogen-rich top gas from the cryogenic unit can be partly recycled to the membrane unit to increase the hydrogen recovery ratio and CO2 capture ratio. This paper investigates the influence of central process design parameters on important process performance indicators such as hydrogen recovery ratio and CO2 capture ratio.

title: Analysis for a safer design of high pressure oxygen pressure reducing stations in steel plants.

description: A pressure reducing station (PRS) in a steel plant controls the pressure and flow of high pressure oxygen from a cryogenic air separation plant. Metallic components in PRS are vulnerable to fire in pure oxygen environment. Particles accumulated in filters are the most visible sources of ignition. However, in many fire incidents, the actual source of ignition is found to lie a few meters upstream of filter. It is hypothesized here that particles charged with static electricity accumulate inside pipe and hit the pipe wall in all directions when the flow suddenly increases due to some operational reasons. The resultant kinetic energy can ignite the particle. Theoretical confirmation of this possibility may facilitate laboratory experiments and design changes in system configuration that may finally prevent fire in a PRS. Computational fluid dynamics (CFD) analysis is used to verify the possibility of particle accumulation upstream of the filter.

title: Energy an exergy analysis of using liquid air for generating air conditioning and power for domestic buildings.

description: Conventional air conditioning systems consume significant amount of energy particularly during the peak period, and cold energy storage in form of liquid Air (LAir), which is produced using renewable energy sources or surplus electricity at the off-peak period, is anticipated as an alternative technique that provides air conditioning as well as generating power for domestic and/or industrial applications. Therefore, the current work presents energetic and exergetic analysis of a combined cryogenic cycle that fuelled by LAir and uses the building cooling load as heat source. The analysis was carried out from thermodynamic point view using MATLAB combined with REFPROP software. Results showed that, using LAir to provide air conditioning and power is a promising technique leads to save energy and to reduce the peak electricity demands. The cycle the thermal and exergy efficiencies reached 47 % and 59 %, respectively. Considering the two energies output (cooling and power) more than 65 % of the LAir energy production was recovered.
