    The performances of an atomic frequency standard depend drastically on the observation time of the atoms. The interrogation of laser cooled atoms allows to obtain about half a second interaction time in a fountain geometry. This duration could be much more varied in absence of gravity, and would allow a better trade-off between stability and accuracy. The application of this principle is the aim of the PHARAO project, that should attend to the ACES mission planned in 2006 onboard the International Space Station. The first part of this thesis deals with the cold Cs{sup 133} PHARAO fountain. This clock stems from the transformation of a space clock prototype previously tested in microgravity. A detailed evaluation of the whole frequency shifts has been carried out, reaching a 7.7 10{sup -16} accuracy and a 1.7 10{sup -13}{tau}{sup -1/2} short term stability. These values are obtained for 4 10{sup 5} detected atoms, that provides a good stability-accuracy trade-off. This transportable fountain, built at BNM-SYRTE, has been operating at MPQ in Munich (Germany). The collaboration between the 2 laboratories gave a {approx} 10 improvement factor on the measurement accuracy (1.8 10{sup -14}) for the 1S - 2S two photons hydrogen transition. In a second part of this thesis, we present the characterisation of 2 elements of the PHARAO space clock: the construction of a standard extended cavity laser and the test of the phase symmetry between the two interrogating areas of the space cavity.

    FO1 was the first caesium fountain primary frequency standard in the world. The most recent evaluation in 2002 before improvement reached an accuracy of 1*10{sup -15} when operated with optical molasses. Working as an extremely precise and stable instrument, FO1 has contributed to fundamental physics and technical measurements: - Frequency comparison between Cs and Rb fountains over an interval of 5 years sets an upper limit for a possible variation of the fine structure constant as |alpha/alpha| < 2*10{sup -15}/y. The resolution is about 5 times better than the previous test in our laboratory. The projected accuracy of the space clock PHARAO is 1*10{sup -16}. We confirmed its Ramsey cavity performance by testing the phase difference between the two interaction zones in FO1. The measured temperature T dependent frequency shift of the Cs clock induced by the blackbody radiation field is given as nu(T)=154(6)*10{sup -6}*(T/300){sup 4}[1+{epsilon}(T/300){sup 2}] Hz with the theoretical value {epsilon} = 0,014. The obtained accuracy represents a 3 times improvement over the previous measurement by the PTB group. Some improvements have been carried out on FO1. The new FO1 version works directly with optical molasses loaded by a laser slowed atomic beam. The application of the adiabatic passage method to perform the state selection allows us to determine the atom number dependent frequency shifts due to the cold collision and cavity pulling effects at a level of of 10{sup -16}. Recently, the obtained frequency stability is 2,8*10{sup -14}*{tau}{sup -1/2} for about 4*10{sup 6} detected atoms. The accuracy is currently under evaluation, the expected value is a few times 10{sup -16}. (author)

  9. The Fontaine Pluton : an early Ross Orogeny calc-alkaline gabbro from southern Victoria Land, Antarctica

    International Nuclear Information System (INIS)

    The Fontaine Pluton is a previously undescribed mafic intrusion outcropping at Fontaine Bluff on the south side of the Carlyon Glacier in southern Victoria Land, Antarctica. It is the southern-most member of a laterally extensive mafic suite emplaced at mid-crustal depths during the initial stages of the Ross Orogeny. The pluton comprises recrystallised hornblende-biotite gabbro, which in places shows well-defined centimetre to metre scale primary igneous layering. Recrystallised ultramafic enclaves composed of amphibole-chlorite-talc are inferred to be remnants of a chemically and mineralogically distinct cumulate fraction. The intrusion has a 87Sr/86Sr(i) ratio of 0.70679 and a 143Nd/144Nd(i) ratio of 0.51187 (εNd(i) = -1.2). This, coupled with other geochemical data, implies that the Fontaine Pluton was formed by c. 15% partial melting of a depleted mantle source that was subsequently contaminated by continental crust. Preliminary U-Pb geochronology on zircon suggests an emplacement age for the pluton of 546 ± 10 Ma. These new data indicate that Ross Orogeny magmatism in this area of southern Victoria Land was initiated in the late Neoproterozoic along a subducting plate margin.

Les calculs théoriques prévoient une réduction du bruit atomique. Il est également possible de réduire les fluctuations du spin associé à la cohérence entre états excités. Nous nous proposons de démontrer ces réductions de bruit a l'aide du bruit de polarisation d'une sonde résonante. Nous avons tout d'abord observé la compression du bruit de polarisation de la pompe sous la limite quantique standard de l'ordre de 13%. Un modèle théorique est développé pour rendre compte des phénomènes.

    A brief survey is first given of the general theorems of Boodle's algebra and of sequence systems using D.A. Huffmans theory. Some indications are then given concerning the setting-up and the operation of digital computers and also of the principal codes used in digital techniques. It is then shown how digitalisation in atomic pile control makes it possible to use new techniques having the following advantages in particular: greater working safety, a higher degree of centralisation, and suppression of the linear elements. A few examples are given of the application of these techniques to control, particularly with respect to the measurement of the neutronic power and of the period and also of course, to the treatment of the data and the sequence automatisms. The advantage of using digital techniques in the shutdown channels is also examined. Finally a review is given of the technology and the viability of the control devices used.

We have thus had to consider the wishes occurring in piles during their operation and also their behaviour in the dynamic state The present work deals mainly with the importance of intrinsic safety devices, with the influence of reactivity variations on the power fluctuations during accidental operation, and with the development of robust and reliable safety appliances. The starting p accident has been especially studied both for low-flux piles where a compromise is necessary between the response time of the safety appliances and the statistical fluctuations and for high lux piles where xenon poisoning has an effect on the lower limit of the velocity of reactivity liberation. The desirability has been stressed of automation as a safety factor in atomic pile control. The details required for an understanding of the diagrams of the apparatus are given.

A visible absorption of a sharp and saturated spectral line in a gas requires a low pressure, so a long path without blushing as a cosmological redshift.

    We developed a method of measurement of the frequency shift due to the collisions between cold atoms. This is the main systematic limitation for the accuracy of the Cs{sup 133} based fountains ({approx} 10{sup -15} in relative frequency). Consequently, we can measure this effect near 0.5% This opens prospects for improvements of the fountains performances in term of accuracy until 10{sup -16}. The fountain has also obtained a stability about 10{sup -14} at 1 s. We discovered for the first time, at very low magnetic field (5 {+-} 1 mG), Feshbach resonances. We also took a new absolute measurement of the hyperfine transition of the Rb{sup 87}, which is the most precise ever carried out and is used now as definition for the secondary standard. By comparing this value with those measured the previous years, we could carry out a test of the stability of the fine structure constant on the level of 10{sup -15} /yr. We led local comparisons between atomic fountains and the other fountains of the laboratory. Most stable it is unrolled with a combined stability of 5.10{sup -14} at 1 s. The behavior of the difference of the two clocks goes like white frequency noise up to 3.10{sup -16}. The assessment of the dual fountain accuracy budget has been evaluated at 7.10{sup -16} for the cesium part and 8.10{sup -16} for the rubidium part. We contributed to the realization of the scale of International Atomic Time, by series of calibrations of hydrogen masers. An atomic comparison of fountain by satellite links was tested between our laboratory and our German counterpart. This measurement has determined the good agreement between the two clocks. (author)

  1. Disposal of the radioactive effluents at the 'Commissariat a l'Energie Atomique'. Treatment leading to evacuation into a river

    International Nuclear Information System (INIS)

    1) The problems dealing with the treatment of the radioactive effluents at the 'Commissariat a l'Energie Atomique' have been studied in order to allow evacuation into a river - after treatment - with respect for the standards regarding radiation protection. 2) At Saclay where there is no possibility of evacuating the effluents, the liquids are directed towards Fontenay-aux-Roses by means of tank wagons. They are removed temporarily into the sewers and will be evacuated later on into the Seine. 3) ln Le Bouchet, the effluents coming from the Factory where urano-thorianite ore is treated will undergo a two stages treatment. The elimination of radium in the first phase facilitates decontamination in the second phase. 4) In Marcoule: a study of synthetic effluents of the Marcoule type is being carried on in order to perfect a selective elimination method of Sr90 and Cs137 by coprecipitation. 5) In the general case of the final evacuation into a river, the following problems have been studied: - pre-dilution of treated waters between the storing tanks and the river; - admission in the river; dilution in the river (preliminary study by means of a tracer); - evolution of the activity in the water of the river (adsorption by inert or living elements), contamination of the banks; - locating of the site; - isotopic dilution. 6) Circumstantial study of that last problem. 7) The quantity of a given product in water conditions the isotopic dilution of its radioactive isotopes. When the analysis shows the lack of an element, stable isotopes should be added in order to compensate it. 8) That method led to difficult analysis (specially as far as Sr90 is concerned), for the percentage of stable isotopes necessary to an important isotopic dilution is very low. 9) The standard regarding the quantity of Sr90 in drinking water is 8.10-8 c/m3 or 4.10-10 g/m3. So a percentage of 40 μg/litre of Sr is enough which is difficult to find out in loaded water, 10) Important elements other than

    This work deals with the experimental realization of an ultracold, magnetically guided atomic beam in the collisional regime. After a detailed description of the experimental setup developed for this purpose, a method to measure the beam temperature with radio-frequency spectroscopy is proposed theoretically and demonstrated experimentally. The variations in temperature, phase-space density and elastic collision rate of the beam during a cycle evaporation-rethermalization are calculated. Two-antenna radio-frequency evaporation experiments are then described. They allow one to demonstrate the occurrence of elastic collisions within the atomic beam. Two Hamiltonian methods allowing one to increase the elastic collision rate are then studied theoretically and investigated experimentally. The gain in the elastic collision rate obtained this way is then used in order to cool the beam by means of ten evaporation zones, thus increasing the beam's phase-space density by one order of magnitude. Finally, a detailed theoretical study of the evaporation kinetics shows that a ten-fold increase of the collision rate obtained so far should be sufficient to achieve quantum degeneracy. Cet ouvrage traite de la réalisation expérimentale d'un jet atomique ultrafroid guidé magnétiquement, dans le régime collisionnel. Après une description détaillée du dispositif expérimental développé à cette fin, une méthode de thermométrie par spectroscopie radio-fréquence est proposée et démontrée expérimentalement. Les variations de température, densité dans l'espace des phases et taux de collisions élastiques du jet au cours d'un cycle évaporation-rethermalisation sont calculées. Des expériences d'évaporation radio-fréquence à deux antennes sont ensuite présentées, qui permettent de prouver l'existence de collisions au sein du jet. Deux méthodes permettant d'augmenter le taux de collisions sont ensuite étudiées théoriquement, puis mises en œuvre. Le gain en taux

  5. A difficult investment: the recruiting of scientific and technical personnel for the Commissariat a l'Energie Atomique

    International Nuclear Information System (INIS)

    Presentation: the situation of France. 1. Part: estimation of requirements. The building of an industrial site thus created demands for huge 'investments' in scientific personnel. 1) Overall evaluation of needs; the teaching system does not produce a sufficient number of specialists. The steps taken to remedy this will not be felt before 1960. 2) Special needs of the C.E.A.: the application of 5 year plans has led to a rapid increase in staff. 2. Part: means adopted by the C.E.A. 1) Recruiting system: for various reasons (competition from private industry, number of specialities represented): - recruiting on a permanent basis; - recruiting of a comparatively large number of women scientists and technicians, etc. 2) Varied means of training: temporary employment, grants, competitions within the teaching system and in the professional training organisations. Conclusion: considerable recruiting of scientific staff by the C.E.A., but the training systems in operation represent a long-term investment for the national economy. (author)

    Full Text Available Cet article présente la méthode mise au point par l'Institut Français du Pétrole pour déterminer par absorption atomique sans flamme, les traces de mercure métallique contenu dans un gaz naturel. La méthode d'analyse nécessite une extraction du mercure soit sous forme d'ion mercurique en faisant passer le gaz dans une solution oxydante, soit sous forme d'amalgame avec de l'or ou de l'argent. Le premier mode opératoire s'applique aux échantillons dont la concentration en mercure est supérieure à I ttg/Nm3, le second pour des concentrations inférieures à 5 pg/Nm3. Les seuils de détection sont respectivement 10 ng (en solution et 0,3 ng (en amalgame. La répétabilité pour 100 ng de mercure (en amalgame est de ± 7% pour une probabilité de.95 %. En conclusion, dans un échantillon de gaz naturel, compte tenu du volume des prélèvements effectués, il est possible de détecter des concentrations de l'ordre du nanogramme de mercure par mètre cube de gaz. This article describes the method developed by IFP using flameless atomic absorption to determine metallic mercury traces in a natural gas. The analyst method requires a mercury extraction either in the form of mercuric ions by making the gas pass through an oxidizing solution or in the form of an amalgam with gold or silver. The former operating method applies ta samples having a mercury concentration greater than I !ag/Nm3, and the latter for concentrations smaller than 5 (-Lg/Nm3. Detection thresholds are respectively 10 ng (in solution and 0.3 ng (in amalgam. The repeatability for 100 ng of mercury (in amalgam is ± 7 % with a probability of 95%. To conclude, in a sample of natural gas, considering the volume of the samples taken, it is possible ta detect concentrations in the vicinity of one nanogrom of mercury per cubic meter of gas.

  7. Part 1: The detection of criticality accidents in the Commissariat a l'Energie Atomique. Part 2: The Burst Slug Detection

    International Nuclear Information System (INIS)

    In all installations where fissionable materials are handled in quantities virtually greater than the critical mass, there exists permanent risk of accidental nuclear excursion entailing a serious irradiation hazard to the personnel, in spite of all the precautions that might be taken. Immediate detection followed by rapid evacuation greatly limits the risks of irradiation due to the fission products or to the sustained nuclear reaction. The necessity for a suitable equipment for the detection of accidents of criticality is imposed by the fact that the physical phenomena accompanying a nuclear, excursion are insufficient to follow the alarm, and may lead to confusion.

    Cette thèse présente l'étude expérimentale et théorique des propriétés magétiques de films ultraminces de cobalt épitaxiés sur substrats d'or polycristallins. Les mesures des cycles d'hystérésis confirment la présence (précédemment observée par résonance ferromagnétique) d'une forte anisotropie d'interface s'opposant au champ démagnétisant, et donnant lieu, pour des épaisseurs de cobalt inférieures à 6 plans atomiques, à un basculement de l'axe de facile aimantation perpendiculairement au pla...

    In all installations where fissionable materials are handled in quantities virtually greater than the critical mass, there exists permanent risk of accidental nuclear excursion entailing a serious irradiation hazard to the personnel, in spite of all the precautions that might be taken. Immediate detection followed by rapid evacuation greatly limits the risks of irradiation due to the fission products or to the sustained nuclear reaction. The necessity for a suitable equipment for the detection of accidents of criticality is imposed by the fact that the physical phenomena accompanying a nuclear, excursion are insufficient to follow the alarm, and may lead to confusion. Taking into account the accidents which have occurred and the role expected from a detector, we choose a dose integration device for the detecting probe proper, and a system based on the coincidence of several information to trigger the alarm. At the demand of the Commission des Masses Critiques, the minimal physical and electronic features required to obtain a very reliable system with minimal risk of false alarm has been established.

    Full Text Available Background: Numerous Clinical studies have reported the safety and efficacy of injection of one Marrow and Peripheral Blood Mononuclear cells in patients with lower limb ischemia. Earlier we have reported the six months follow-up of successful application of autologous bone marrow mononuclear cells in patients with Fontaine Stage IV critical limb ischemia due to diabetes. As a continuation of the previous study, herein we report the long term results of the six patients after a follow-up for five years.Materials and Methods: Six Diabetic patients with Fontaine Stage IV critical limb ischemia with ulcers were given intra-lesional injections of their autologous bone marrow mononuclear cells (BMMNC, isolated following the cGMP protocols. The patients have been followed up at regular intervals for five years after the treatment with all relevant clinical investigations. Results: Six months follow-up results revealed that all the patients showed improvements with appearance of healthy granulation tissue and uniform revascularization. Complete healing was reported at a mean duration of nine months in five patients and one patient died due to a complication of renal failure, peritoneal dialysis and cardiac failure, which were unrelated to the BMMNC injection. Five year continuous follow-up revealed that the healed tissue with or without skin grafting remained healthy in all the five patients and two of the patients are able to walk without support with a pain free walking distance of greater than 100m.There were no adverse effects in any of the patients. Conclusion: Autologous bone marrow stem cell therapy has been found to be salvaging the affected limb in patients with Fontaine Stage IV Critical Limb ischemia patients where revascularization was not feasible. Hence with our experience of six patients we recommend that the same should be considered in patients of similar clinical parameters before considering an amputation.

    In nuclear resonance fluorescence as in the optical field abnormal dispersion curves are related to the absorption lines. It is possible, by using quadrupolar or magnetic splitting of the line in the case of recoilless resonance fluorescence (Moessbauer effect) to obtain differential dispersion effects between the two orthogonal linear or the two inverse circular components of the incident gamma radiation. These effects induce bi-refraction phenomena or Faraday rotation on the gamma beam, which have been studied on Fe-57 enriched absorbers. (author) [French] Comme dans le domaine optique, aux raies d'absorption de fluorescence resonnante des noyaux atomiques sont associees des courbes de dispersion anormale. Les decompositions des raies d'absorption de fluorescence resonnante sans recul (raies Moessbauer) par couplage quadrupolaire ou effet Zeeman permettent d'obtenir des effets dispersifs differentiels entre composantes lineaires orthogonales ou circulaires inverses du rayonnement gamma incident. Ces effets se traduisent par des phenomenes de birefringence ou de rotation Faraday, qui ont pu etre etudies sur des milieux enrichis en fer-57. (auteur)

    The US DOE Center for Engineering Systems Advanced Research (CESAR) at the Oak Ridge National Laboratory (ORNL) and the Commissariat a l'Energie Atomique's (CEA) Office de Robotique et Productique within the Directorat a la Valorization are working toward a long-term cooperative agreement and relationship in the area of Intelligent Systems Research (ISR). This report presents the proceedings of the first CESAR/CEA Workshop on Autonomous Mobile Robots which took place at ORNL on May 30, 31 and June 1, 1989. The purpose of the workshop was to present and discuss methodologies and algorithms under development at the two facilities in the area of perception and navigation for autonomous mobile robots in unstructured environments. Experimental demonstration of the algorithms and comparison of some of their features were proposed to take place within the framework of a previously mutually agreed-upon demonstration scenario or base-case.'' The base-case scenario described in detail in Appendix A, involved autonomous navigation by the robot in an a priori unknown environment with dynamic obstacles, in order to reach a predetermined goal. From the intermediate goal location, the robot had to search for and locate a control panel, move toward it, and dock in front of the panel face. The CESAR demonstration was successfully accomplished using the HERMIES-IIB robot while subsets of the CEA demonstration performed using the ARES robot simulation and animation system were presented. The first session of the workshop focused on these experimental demonstrations and on the needs and considerations for establishing benchmarks'' for testing autonomous robot control algorithms.

Les résultats de la calibration des spectromètres à dispersion d'énergie, à excitation par sources radioactives (55Fe, 109Cd et 241Am) et à excitation secondaire (cible secondaire Mo et Cu) du Centre National pour l'Energie, les Sciences et les Techniques Nucléaires (CNESTEN, Rabat, Maroc) sur des échantillons étalons de références de l'Agence International de l'Energie Atomique (AIEA) et du Community Bureau of Référence (BCR) ont été comparés aux résultats d'analyse des mêmes échantillons étalons par la spectrométrie X à dispersion de longueur d'onde (WD-XRF) et par spectrométrie d'émission atomique à source plasma couplé par induction (ICP-AES) au département GENERIC du centre SPIN à l'Ecole des Mines de Saint-Etienne (France). Les trois techniques d'analyse utilisées donnent des résultats comparables pour le dosage des éléments majeurs, alors que pour les traces on note des déviations importantes à cause des effets de matrice qui sont difficiles à corriger dans le cas de la fluorescence X.

    This thesis is devoted to studies which prepared the construction of an atom Mach-Zehnder interferometer. In such an interferometer, the propagating waves are spatially separated, and the internal state of the atom is not modified. The beam-splitters are diffraction gratings, consisting of standing optical waves near-resonant with an atomic transition. We use the Bloch functions to define the atom wave inside the standing wave grating and thus explain the diffraction process in different cases. We developed a nearly all-analytical model for the propagation of an atom wave inside a Mach-Zehnder interferometer. The contrast of the signal is studied for many cases: phase or amplitude gratings, effects of extra paths, effects of the main mismatches, monochromatic or lightly polychromatic sources. Finally, we discuss three interferometric measurements we think very interesting. The first, the index of refraction of gas for atomic waves, is studied in detail, with numerical simulations. The other measures we propose deal with the electrical properties of lithium. We discuss the ultimate limit for the measure of the static electric polarizability of lithium by atomic interferometry. Then, we discuss how one could measure the possible charge of the lithium atom. We conclude that an optically cooled and collimated atom beam would improve precision. (author)

  16. Cleansing methodology of sites and its applications

    International Nuclear Information System (INIS)

    The Commissariat a l'Energie Atomique (CEA, French Atomic Energy Commission) has set up over the last 10 years an innovative methodology aiming at characterizing radiological contaminations. The application of the latter relies on various tools such as expertise vehicles with impressive detection performances (VEgAS) and recently developed software platform called Kartotrak. A Geographic Information System tailored to radiological needs constitutes the heart of the platform; it is surrounded by several modules aiming at sampling optimization (Stratege), data analysis and geostatistical modeling (Krigeo), real-time monitoring (Kartotrak- RT) and validation of cleaning efficiency (Pescar). This paper presents the different tools which provide exhaustive instruments for the follow-up of decontamination projects, from doubt removal to the verification of the decontamination process.

    1- Reasons for its creation. The Electricite de France, and industries interested in the development of atomic energy, have requested the Commissariat a l'Energie atomique to train scientists who will be able to study pile planning and to be in charge of their construction. 2- Recruiting and enrolment fees. The demand for enrolment has always exceeded the possibilities. This year the courses have been attended by 74 permanent students, including 20 foreigners, and some hundred part-time listeners. All students are already scientists or have high university qualifications. Enrot fees: 250 000 F for students, 125 000 F for part-time attendance. 3- Organisation of the teaching. This consists of two branches: physics and chemistry, and in each branch: some hundred lectures, some thirty sessions of practical work, periods of work in the departments, study of a reactor project by a group of 4 or 5 students. The course takes place during the university year 1 november to 14 july. 4- Qualifications. A final examination, combining the results from two theoretical tests, from the practical work, from the period of work in the establishment and from the reactor project leads to a diploma in atomic energy. In reality new scientists are not produced, a new mention is merely added to a diploma already held. Results have always been excellent; the percentage of failures is very small. 5- Placing of graduates. They all return to their original industries, who have paid their salaries and enrolment fees whilst giving up their services during the 9 months duration of the course. 6- Similar ventures. A similar course has been created at the C.F.N. Grenoble. Whilst the Saclay course is particularly for scientists already working, that at Grenoble is destined in principle for young scientists leaving college. 7- Conclusion. This organization is satisfactory both for the students and the industries. The C.E.A. works towards yearly improvement, and hopes to welcome large numbers of

    This thesis describes the characterization of atmospheric petroleum distillates (kerosenes and gas-oils) and vacuum distillates by hyphenated technic of Gas Chromatography and Atomic Emission Detector (GC-AED). A gas chromatographic simulated distillation, which gives the weight % of sample as a function of the petroleum cut temperature, was adapted to the GC-AED to obtain an original information about the elemental composition profile. After generalities, historic of the development of the instrument and the first petroleum applications are described. In the experimental part, analytical conditions used, different technics of characterisation of distillates and the base of samples analyzed are exposed. After a study of the GC-AED`s performances for the target elements (C, H, S, N), a quantitative method for the elemental analysis of distillates was developed and validated at three levels: total elemental analysis, simulated distillation and elemental composition as a function of the distillation profile. Finally, different ways for the applications of the GC-AED in order to characterize the distillates were explored, in particular to classify products and predict some petroleum properties (cetane number, density,...). The more interesting outlook seems to be the prediction of some properties as a function of the distillation profile. (author) 155 refs.

    The author presents considerations which should prove to be of interest to all those who have to design, to construct and to operate a nuclear research centre. A large number of the ideas presented can also be applied to non-nuclear scientific research centres. In his report the author reviews: various problems with which the constructor is faced: ground-plan, infrastructure, buildings and the large units of scientific equipment in the centre, and those problems facing the director: maintenance, production, supplies, security. The author stresses the relationship which ought to exist between the research workers and the management. With this aim in view he proposes the creation of National School for Administration in Research which would train administrative executives for public or private organisations; they would be specialised in the fields of fundamental or applied research.

    The problems dealing with the treatment of the radioactive effluents at the 'Commissariat a l'Energie Atomique' have been studied in order to allow evacuation into a river - after treatment - with respect for the standards regarding radiation protection. 2) At Saclay where there is no possibility of evacuating the effluents, the liquids are directed towards Fontenay-aux-Roses by means of tank wagons. They are removed temporarily into the sewers and will be evacuated later on into the Seine. 3) ln Le Bouchet, the effluents coming from the Factory where urano-thorianite ore is treated will undergo a two stages treatment. The elimination of radium in the first phase facilitates decontamination in the second phase. 4) In Marcoule: a study of synthetic effluents of the Marcoule type is being carried on in order to perfect a selective elimination method of Sr{sup 90} and Cs{sup 137} by coprecipitation. 5) In the general case of the final evacuation into a river, the following problems have been studied: - pre-dilution of treated waters between the storing tanks and the river; - admission in the river; dilution in the river (preliminary study by means of a tracer); - evolution of the activity in the water of the river (adsorption by inert or living elements), contamination of the banks; - locating of the site; - isotopic dilution. 6) Circumstantial study of that last problem. 7) The quantity of a given product in water conditions the isotopic dilution of its radioactive isotopes. When the analysis shows the lack of an element, stable isotopes should be added in order to compensate it. 8) That method led to difficult analysis (specially as far as Sr{sup 90} is concerned), for the percentage of stable isotopes necessary to an important isotopic dilution is very low. 9) The standard regarding the quantity of Sr{sup 90} in drinking water is 8.10{sup -8} c/m{sup 3} or 4.10{sup -10} g/m{sup 3}. So a percentage of 40 {mu}g/litre of Sr is enough which is difficult

    The ''Centre d'Etudes de Limeil-Valenton'' (CEL-V) of the French ''Commissariat a l'Energie Atomique'' (CEA) has recently submitted a conceptual design (Avant Projet Sommaire) concerning the construction of a two millions of joules solid-state laser for Inertial Confinement Fusion applications. This is the result of a two year collaboration with the Lawrence Livermore National Laboratory in the USA. After recalling the laser performance (Energy, Power, etc...) required to produce a fusion energy as high as ten times the laser energy we will describe the structure of such a facility. Together with the laser itself we will describe the target chamber, the controls and the data acquisition and the building. This presentation will outline the technology and physics issues related to such a facility: beam smoothing, beam to beam power balance, number of beams versus beam dimension, amplifier and spatial filter design, multi-pass concept, optical components fabrication, to name a few. Taking into account the NIF project, we will particularly emphasize the differences between the US and French approach. -Abstract only- (Author)

  11. A four-year investigation of Brayton cycle systems for future French space power applications

    International Nuclear Information System (INIS)

    Within the framework of a joint program initiated in 1983 by the two French Government Agencies C.N.E.S. (Centre National d'Etudes Spatiales) and C.E.A. (Commissariat a l'Energie Atomique), in order to study space nuclear power systems for future ARIANE 5 applications, extensive investigations have dealt with the Brayton cycle, which has been selected as the energy conversion system. Several aspects can be mentioned in this field: matching of the power system to the available radiator dimensions up to 200 kWe, direct or indirect waste heat transfer to the radiator, the use of a recuperator, recent work on moderate (25 kWe) power levels, simulation studies related to various operating conditions, and general system optimization. A limited experimental program is starting on some crucial technology areas including a first contract to the Industry concerning the turbogenerator. Particular attention is being paid to the significance of the adoption of a Brayton cycle for space applications involving a nuclear heat source, which can be either a liquid-metal-cooled or a gas-cooled reactor. For a gas-cooled reactor, direct-cycle system, the relevance to the reactor technology and the concept for moderator thermal conditioning is particularly addressed

  12. The current CEA/DRN safety approach for the design and the assessment of non-electrical applications of nuclear heat

    International Nuclear Information System (INIS)

    This paper presents the basis of the safety approach currently implemented by the Commissariat a l'Energie Atomique - Nuclear Reactor Directorate (CEA/DRN), both for the design and the assessment of innovative systems and future nuclear installations. It is considered that the described approach is applicable to the plants built for non-electrical applications of nuclear heat. This is typically the case of Nuclear Desalination Installations. This approach is the result of the experience maturated, within the context of the CEA/DRN Innovative Programme, through practical applications over several future concepts (both fission and fusion plants). The background of this experience is structured coherently with the European Safety Authorities recommendations, the European Utilities Requirements (EUR) and the ''fundamental safety objectives'' defined by the IAEA. The Defence In Depth principle and its application, by means, among others, of the barrier concept, remains the basis of the safety design process of future nuclear installations. Its adequacy is checked through the safety assessment. The methodology for Lines of Defence (LOD) implementation as well as the one for the LOD architecture assessment is shown and motivated. The document shows that the clear and unambiguous definition of the safety approach provides an essential base for the organisation of the design tasks, being sure that the safety aspects are correctly taken into account and implemented, and for an adequate safety assessment of the final design, both from qualitative point of view as well as for the quantitative safety analysis.

    International Nuclear Information System (INIS)

    Objective: To evaluate the clinical efficiency and security of SilverHawk directional atherectomy device in treating arteriosclerosis obliterans of lower extremity. Methods: Seven patients with lower extremity ischemia were treated with SilverHawk directional atherectomy. The lesions length varied from 1.8 to 14.5 cm. Clinical symptoms (Fontaine classification) included 4 cases of grade Ⅱ b, I case of grade Ⅲ, 2 cases of grade Ⅳ. The ABI varied from 0.28 to 0.65. Patency was evaluated with color duplex sonography or CTA besides clinical examination during follow-up. Results: Seven occlusive lesions were recanalizated successfully. The technical success (residual stenosis < 30%) rate was 100%. Clinical symptoms were obviously improved or disappeared. The ABI varied from 0.82 to 1.18 (P=0.002), and Fontaine classification included 6 cases of Ⅰ; 1 case of Ⅱ a. Patency rate was 100% and the ABI varied from 0.75 to 1.14 (P=0.938). Fontaine classifications keep consistent 1-6 months after operation. Conclusion: SilverHawk directional atherectomy was a safe and effective way for treatment of lower arteriosclerosis obliteran.

    The establishment of safety standards is one of the tasks conferred upon the International Atomic Energy Agency (IAEA) by its statute. These standards are intended to protect the health of persons and reduce as far as possible the hazards related to the harmful effects of ionising radiation on persons and property. The IAEA must apply these standards to its own activities. States must apply them to the operations that they carry out with IAEA assistance. The IAEA provides support for the use or application of its standards to states that request it. This support may take the form of training programmes or expert task forces. The nuclear safety activities of the IAEA, based essentially on its safety standards and on the support provided to its member states, give rise to very substantial cooperation programmes with the European Union.

    This work shows the study of atom-molecule collision processes in the high velocity domain (v=4,5 a.u). The molecules concerned by this work are small unsaturated hydrocarbons C{sub 1-4}H and C{sub 3}H{sub 2}. Molecules are accelerated with the Tandem accelerator in Orsay and their fragmentation is analyzed by the 4{pi}, 100% efficient detector, AGAT. Thanks to a shape analysis of the current signal from the silicon detectors in association with the well known grid method, we are able to measure all the fragmentation channels of the incident molecule. These dissociation measurements have been introduced in the modelization of two objects of the interstellar medium in which a lot of hydrocarbon molecules have been observed (TMC1, horse-head nebula). We have extended our branching ratios obtained by high velocity collision to other electronic processes included in the chemical database like photodissociation and dissociative recombination. This procedure is feasible under an assumption of the statistical point of view of the molecular fragmentation. The deviations following our modification are very small in the modelization of TMC1 but significant in the photodissociation region. The first part is dedicated to the description of the experimental setting that has enabled us to study the fragmentation of C{sub n}H{sub m} molecules: the Orsay's Tandem accelerator and the Agat detector. The second part deals with negative ion sources and particularly with the Sahat source that is based on electronic impact and has shown good features for the production of anions and correct stability for its use with accelerators. The third part is dedicated to the experimental results in terms of cross-sections, number of fragments and branching ratios, associated to the various collisional processes. The last part presents an application of our measurement of fragmentation data to astro-chemistry. In this field, the simulation codes of the inter-stellar medium require databases

  20. Changes in the legal status of the Commissariat a l'energie atomique (Cea)

    International Nuclear Information System (INIS)

    The Cea a public research institution was re-classified among the energy research establishments (11 december 2008). The Cea, as the result of exceptional circumstances and complex activities, is today entering into a new era and must confront many national and supranational challenges. It is preparing, in effect, for a future nuclear industry (safer, less polluting, non-proliferating and more economical) and is conducting research into other energy solutions within the framework of sustainable development and limited greenhouse gas effects (hydrogen technology, fusion, alternative energy technologies). It also has another goal, to make technological research available to industry, not only by developing micro and nano-technologies or even to contribute technology for the benefit of scientific knowledge of living creatures, matter, climate and the environment. The new classification of the Cea as a research establishment in the field of energy, a heading which includes three other entities (A.N.D.R.A., A.D.E.M.E. and I.F.P.), raises questions about its specialization and diversification. However, no substantive change was made to the drafting of the legislative provisions so it is possible to imagine that the Cea takes initiatives in other fields, at the instigation or with the approval of the government, a matter which is facilitated by its classification in the E.P.I.C. category (public establishment at industrial and commercial character). The Cea also represents France in international organisations in the nuclear sector, such as the OECD Nuclear energy agency (Nea), the International atomic energy agency (IAEA) and the European communities. It also participates in intergovernmental negotiations in the nuclear field and ensures any follow-up required with regard to any resulting agreements. today, the Cea plays a major role in the implementation of French nuclear policy with the aim of making available to countries wishing to develop nuclear energy, a framework which guarantees non-proliferation, security and safety. this role is completed by its very active participation in the global energy partnership initiative alongside the United States department of energy. The Cea is also responsible for all french research activities on controlled thermonuclear fusion carried out within the EURATOM framework since 1959.In fact, in Europe, all research into this topic is integrated into one single programme, such as Switzerland, take part in it by means of a contract of association with the European Union which is administered by the Cea. The work is carried out by qualified European research bodies known collectively as the EURATOM fusion associations. (N.C.)

    International Nuclear Information System (INIS)

    The data processing orientations and needs have been relying heavily, for the last 5 years, on CEANET, the general-purpose internal datacommunications network of CEA. All computers and scientific workstations, and most of the office workstations, are connected to CEANET. They are also dependent on nation-wide or world-wide networking facilities. CEANET is a multi-protocol network, with shared infrastructure. The main protocols are: Two standardised protocols, IP (very heavily used) and X25, and two proprietary protocols: SNA and DECnet. Within sites, its main components are Ethemets and FDDI rings. (orig.)

  2. The Josephson effect in atomic contacts; Effect Josephson dans les contacts atomiques

    Chauvin, M

    2005-11-15

    The Josephson effect appears when a weak-link establishes phase coherence between two superconductors. A unifying theory of this effect emerged in the 90's within the framework of mesoscopic physics. Based on two cornerstone concepts, conduction channels and Andreev reflection, it predicts the current-phase relation for the most basic weak-link: a single conduction channel of arbitrary transmission. This thesis illustrates this mesoscopic point of view with experiments on superconducting atomic size contacts. In particular, we have focused on the supercurrent peak around zero voltage, put into evidence the ac Josephson currents in a contact under constant bias voltage (Shapiro resonances and photon assisted multiple Andreev reflections), and performed direct measurements of the current-phase relation.

  3. Comparative analysis of coupled creep-damage model implementations and application

    International Nuclear Information System (INIS)

    Creep rupture of a reactor pressure vessel in a severe accident occurs after complex load and temperature histories leading to interactions between creep deformations, stress relaxation, material damaging and plastic instability. The concepts of continuous damage introduced by Kachanov and Robotnov allow to formulate models coupling elasto-visco-plasticity and damage. However, the integration of such models in a finite element code creates some difficulties related to the strong non-linearity of the constitutive equations. It was feared that different methods of implementation of such a model might lead to different results which, consequently, might limit the application and usefulness of such a model. The Commissariat a l'Energie Atomique (CEA), Electricite de France (EDF) and Framasoft (FRA) have worked out numerical solutions to implement such a model in respectively CASTEM 2000, ASTER and SYSTUS codes. A ''benchmark'' was set up, chosen on the basis of a cylinder studied in the programme ''RUPTHER''. The aim of this paper is not to enter into the numerical details of the implementation of the model, but to present the results of the comparative study made using the three codes mentioned above, on a case of engineering interest. The results of the coupled model will also be compared to an uncoupled model to evaluate differences one can obtain between a simple uncoupled model and a more sophisticated coupled model. The main conclusion drawn from this study is that the different numerical implementations used for the coupled damage-visco-plasticity model give quite consistent results. The numerical difficulty inherent to the integration of the strongly non-linear constitutive equations have been resolved using Runge-Kutta or mid-point rule. The usefulness of the coupled model comes from the fact the uncoupled model leads to too conservative results, at least in the example treated and in particular for the uncoupled analysis under the hypothesis of the small

    Full Text Available Nous avons cherché à faire le point sur la fabrication de couches minces de diamant qui, après avoir été très étudiée aux États-Unis vers la fin des années 1950, a fait l'objet d'une percée technologique soviétique en 1977. Celle-ci utilise l'effet solvant de l'hydrogène mélangé à un peu de méthane. Transformé en hydrogène atomique par décharge électrique, il interdit le dépôt de graphite et par conséquent permet seulement celui du diamant. Ce résultat est riche d'applications prometteuses en mécanique, en optique, en électronique. . . et constitue un élément clé pour la recherche spatiale. Les Japonais ont mis cinq ans pour réagir et les Américains cinq autres années. Mais ces derniers espèrent refaire leur retard grâce au programme Diamond Technology Initiative établi dans le cadre de l'initiative de Défense Stratégique (Guerre des Étoiles. Les retombées de ces travaux devraient concerner l'industrie pétrolière (paliers, trépans, capteurs en milieu extrême. This article reviews the depositing of diamond thin layers. After much research had been done on this technique in the United States in the late 1950s, a technological breakthrough was made by the Soviets in 1977. This breakthrough uses the solventeffect of hydrogen mixed with a bit of methane. This is transformed into atomic hydrogen by an electric discharge, thus preventing graphite from being deposited and hence enabling only diamond to be deposited. This achievement has a wealth of promising applications in mechanics, optics, electronics, etc. It is also a key element for space research. The Japanese took five years to react and the Americans another five years. But these latter hope to make up for lost time with the Diamond Technology Initiativepromoted within the framework of the Strategic Defense Initiative ( star wars .

    As debates take place in the French Parliament to forbid the extraction of shale in gas in France, the author outlines that, according to some experts, even though some sites might be very interesting, only a fraction of their content could be exploited. He also outlines the actual danger of this exploitation for the environment, notably because hydraulic fracturing has to be used. Although the main operators are American, French big companies possess the required know-how and are gaining experience abroad. Moreover, it seems that shale gas exploitation does not possess a significant job creation potential. The situation of different countries with respect to shale gas exploitation is briefly presented: United States, Canada, China, and Poland. The United States policy on this issue is more precisely described in a last article

  10. COMMERCIAL APPLICATION OF PLASMA MASS SEPARATION IN THE ARCHIMEDES FILTER PLANT

    International Nuclear Information System (INIS)

    This paper describes the commercial application of an innovative plasma mass separator called the Archimedes Filter to a pre-treatment plant that can be integrated into the U.S. Department of Energy (DOE) Hanford and Savannah River Sites to significantly enhance the treatment of radioactive high-level waste. The output of the Archimedes Filter is completely compatible with existing waste immobilization processes such as vitrification and requires no new waste form to be developed. A full-geometric-scale Demonstration Filter Unit (DEMO) has been constructed and is undergoing initial testing at the Archimedes Technology Group Development Facilities in San Diego. Some of the technology and engineering development is being performed by other organizations in collaboration with Archimedes. The Commissariat a l'Energie Atomique (CEA) is developing the plasma calcination technology and all of the associated systems for AFP feed preparation. Two Russian institutes are involved in the development of the ICP torch and injector system. The Remote System Group (UT-Battelle) at ORNL is developing the remote maintenance system for the filter units. Conceptual design of the Archimedes Filter Plant (AFP) is being developed concurrently with the DEMO testing program. The AFP mission is to significantly reduce the cost and accelerate the rate of vitrification of high-level waste by separating low activity waste from the sludge removed from underground storage tanks. Mass separation is accomplished by vaporizing the sludge feed and injecting it into a partially ionized, neutral plasma. In a single pass, heavy ions are deposited near the center of the filter and light mass ions are transported by the plasma to the ends of the cylindrically-shaped vacuum vessel. Responding to the DOE programs for cost reduction and cleanup acceleration, the AFP Project is planned on an expeditious schedule that executes all phases of the project with private sector funding.

    Superconductivity has found many attractive applications in medicine, science, power systems, engineering, transport and electronics. One of the most prominent applications of superconductivity are superconducting magnets e.g. MRI magnets, NMR magnets, accelerator magnets, and magnets for fusion; most applications still use low temperature superconductors. Since the discovery of high temperature superconductivity (HTS) in 1986 there has been a tremendous progress in R&D of HTS material, wires and applications. Especially for power system applications, HTS offers considerable economic benefits. Many HTS demonstrator or prototype applications have been built and successfully tested, and some HTS applications like cables and superconducting fault current limiters seem very close to commercialisation. This paper gives an overview about the present and future HTS applications in power applications, high field magnets and current leads.

    Aerogel materials possess a wide variety of exceptional properties, hence a striking number of applications have developed for them. Many of the commercial applications of aerogels such as catalysts, thermal insulation, windows, and particle detectors are under development and new applications have been publicized since the ISA4 Conference in 1994: e.g., supercapacitors, insulation for heat storage in automobiles, electrodes for capacitive deionization, etc. More applications are evolving as the scientific and engineering community becomes familiar with the unusual and exceptional physical properties of aerogels. In addition to growing commercial applications of aerogels, there are also scientific and technical applications, as well. This paper discusses a variety of technical applications of aerogels. It reports current technical applications under development for which several types of aerogels are formed in custom sizes and shapes

    The Laboratoire National Henri Becquerel (LNHB) is the French National Metrology Laboratory for ionizing radiation since 1969, date of creation of the Bureau National de Metrologie (BNM). According to the reorganization of French metrology in 2005, the BNM was replaced by the Laboratoire National de metrologie et d'Essais (LNE) as National Metrology Institute. In this frame, the LNHB is today one of the four French national laboratories, federated by the LNE to cover the entire domains of metrology (time, length, mass, electricity, and others). The LNHB is in charge of the metrology of absorbed dose and activity. At present, it operates (i) a Manganese-bath for neutron primary standard of flux; (ii) 60Co and 137Cs collimated beams for radiation protection and radiotherapy; (iii) high-energy RX photons and electrons from a LINAC for external radiotherapy; (iv) 192Ir HDR and PDR for brachytherapy; (v) soft X rays for diagnosis, mammography and industry; and (vi) beta radiation fields for radiation protection purposes of workers and patients. The mains tasks of the LNHB are (i) to maintain the existing references at the best level; (ii) to create new references meeting the needs of the society for health and industry; and (iii) to transfer the references to the users through Secondary Standard Labs (SSL) or directly when commercial services do not exist. The LNHB is accredited by the French accreditation body (COFRAC) to ISO 17025 and participates in the Mutual Recognition Arrangement (MRA) between National Metrology Institutes

  15. Study of atomic jumps in quasi-crystals; Etude des sauts atomiques dans les quasi-cristaux

    Lyonnard, S

    1997-05-07

    The terminology phason used in quasicrystals to refer to atomic jumps. The study of the hopping process is important for the understanding of many basic issues in quasi-crystallography: structure, stability, diffusion, phase transitions between quasicrystals and approximants, mechanical properties. Quasi-elastic neutron scattering allows to find the characteristics of each elementary jump: chemical species involves, relaxation times, activation energies, jump distances and orientations. We performed a series of experiments in the perfect icosahedral phases AlFeCu and AlMnPd, on both powders and single domain samples, using time-of-flight, backscattering and triple axis spectrometers. We evidenced the existence of very fast phason hopping, and studied about ten different atomic jumps. An unusual temperature dependence has been found systematically: each process is assisted by a thermally activated mechanism. The assistance process has to be determined case by case, but the more plausible explanation invokes assistance by phonons or phason clouds. Moreover, the dependence of the quasi elastic signal as a function of the momentum transfer shows that the jumps are local and do not give rise to any long-range diffusion. Phason hopping mainly corresponds to the atom moving forwards and backwards between two energetically equivalent sites. Finally, we have been able to show that the jumps occur along the various quasi-crystalline symmetry axes. (author) 91 refs.

    Energy Technology Data Exchange (ETDEWEB)

    Barre, V

    2006-06-15

    Kinetic models in alloys aim at predicting the transport properties of a system starting from the microscopic jump frequencies of defects. Such properties are of prior importance in systems which stay out of equilibrium for a long time, as for example irradiated alloys in nuclear reactors. We hereby propose several developments of the recent self-consistent mean field (SCMF) kinetic theory, which deals particularly with the correlation effects due to the coupling of atomic and defect fluxes. They are taken into account through a non-equilibrium distribution function of the system, which is derived from the time evolution of small clusters (of two or more atoms or defects). We therefore introduce a set of 'dynamic' interactions called effective Hamiltonian. The SCMF theory is extended to treat high jump frequency ratios for the vacancy mechanism, as well as the transport through interstitial defects. We use in both cases an atomic model which accounts for the thermodynamic properties of the alloy, as e.g. the t-range order. Those models are eventually applied to predict the diffusion properties in two model alloys of nuclear interest: the concentrated Fe-Ni-Cr solid solution and the dilute Fe(P) alloy. We present adapted atomic models and compare our predictions to experimental data. (author)

  20. PSA applications

    International Nuclear Information System (INIS)

    The IAEA now defines three types of PSA applications: Validation of design and of operation procedures; optimization of plant operation; and regulatory applications. The applications of PSA are manifold: only a few are dealt with here (precursor analysis is dealt with in session 3, topic 4). For each of them, we will do the utmost to demonstrate the main difficulties encountered, EDF's viewpoint on the matter, and the points remaining to be solved. In what follows, unless explicitly stated otherwise, we have made every effort to represent the different applications as they are practiced by all concerned in the international community, and to describe the inherent difficulties the international community has encountered with these applications with all objectivity. It goes without saying that the comments below are simply those of the ESF department, and are submitted here for discussion by the experts. 13 refs

  3. PRIBIC Application

    International Nuclear Information System (INIS)

    PRIBIC plant (Pollutants Reduction In small Biomass Combustion systems) at CEDER is a facility specifically designed to do biomass combustion tests. In these tests is necessary to know the values of different sensors in real time. With this information the PRIBIC plant is regulated to its optimum point of work and its possible to follow the operation criteria and get test objectives. Different electronic instruments record information about the plant operation. A software application was developed to let a centralised motorization of that information. The application communicates with the instrumentation, recovers data, lets operators see data in real time and saves the information in files. An important part of this document describes that application, and some considerations to generalise this kind of developments to other Experimental Plants, including cost estimations. Descriptions of plant, analysis of the problem, result evaluations, and conclusions can also be found in the document. (Author) 13 refs

    In re-listening to the lectures of Charles Townes shortly after the invention of the laser (e.g., in the Boston Science Museum), one can already have a realistic vision of the potentialities of this new tool in the field of medical therapy, as evidenced by the use of the laser in ophthalmology to cure retinal detachment in the 1960's. Since then, applications have flourished in the domain of therapy. We will thus illustrate here only some of the main fields of application of medical lasers. On the opposite, the use of lasers in medical imaging is, with one exception in ophthalmology, still at the development level. It is becoming a diagnostic tool in addition to high performance imaging facilities that are often very expensive (such as CT scan, Magnetic Resonance Imaging (MRI) and nuclear imaging). Even if progress is sometimes slow, one can now image with light inside the human body, in spite of the strong scattering of light by tissues, in the same way as a pathologist sees surgical specimens.

  16. A survey of natural irradiation in France: description and first results of the Commissariat a l'Energie Atomique (CEA) program

    International Nuclear Information System (INIS)

    A survey of the population exposure to natural sources of radiation has been undertaken by the CEA. It is carried out at the level of 'administrative subdivisions'; in each subdivision, 400-500 calcium sulfate dosimeters have been exposed during some 6 months, outside and inside dwellings. In the first subdivisions studied the mean values for external exposure from terrestrial radiation are ranging between 43 and 109 mrad.an-1 (extreme point values: 16 and 258 mrad.an-1) outdoors, and between 43 and 120 mrad.an-1 (extreme point values: 14 and 287 mrad.an-1) indoors. As an average, indoor doses are about 10% higher than outdoor doses. As a complement to this study natural radionuclide concentrations have been determined in wheat samples in some ten regions since 1973. Radium 226 concentrations vary between 0.3 and 4.5 pCi.kg-1. Indoor measurements of radon daughter products will also be carried out

  18. Fragmentation of neutral carbon clusters formed by high velocity atomic collision; Fragmentation d'agregats de carbone neutres formes par collision atomique a haute vitesse

    Martinet, G

    2004-05-01

    The aim of this work is to understand the fragmentation of small neutral carbon clusters formed by high velocity atomic collision on atomic gas. In this experiment, the main way of deexcitation of neutral clusters formed by electron capture with ionic species is the fragmentation. To measure the channels of fragmentation, a new detection tool based on shape analysis of current pulse delivered by semiconductor detectors has been developed. For the first time, all branching ratios of neutral carbon clusters are measured in an unambiguous way for clusters size up to 10 atoms. The measurements have been compared to a statistical model in microcanonical ensemble (Microcanonical Metropolis Monte Carlo). In this model, various structural properties of carbon clusters are required. These data have been calculated with Density Functional Theory (DFT-B3LYP) to find the geometries of the clusters and then with Coupled Clusters (CCSD(T)) formalism to obtain dissociation energies and other quantities needed to compute fragmentation calculations. The experimental branching ratios have been compared to the fragmentation model which has allowed to find an energy distribution deposited in the collision. Finally, specific cluster effect has been found namely a large population of excited states. This behaviour is completely different of the atomic carbon case for which the electron capture in the ground states predominates. (author)

    In this thesis quantum mechanical non-relativistic few-body problem is discussed. Basing on fundamentals ideas from Faddeev and Yakubovski three and four body equations are formulated and solved for fermionic atomic and nuclear systems. Former equations are modified to include long range interactions. Original results for nuclear and molecular physics were obtained: -) positively charged particle scattering on hydrogen atoms was considered; predictions for {pi}{sup +} {yields} H, {mu}{sup +} {yields} H and p{sup +} {yields} H scattering lengths were given. Existence of an unknown, very weakly bound H{sup +}{sub 2} bound state was predicted. -) Motivated by the possible observation of bound four neutron structure at GANIL we have studied compatibility of such an existence within the current nuclear interaction models. -) 4 nucleon scattering at low energies was investigated. Results for n {yields} {sup 3}H, p {yields} {sup 3}H and p {yields} {sup 3}He systems were compared with the experimental data. Validity of realistic nucleon-nucleon interaction models is questioned.

  20. Numerical study of the atomic and electronic structure of some silicon grain boundaries; Etude numerique de la structure atomique et electronique de quelques joints de grains du silicium

    Energy Technology Data Exchange (ETDEWEB)

    Torrent, M

    1996-07-01

    This work contributes to the theoretical study of extended defects in covalent materials. The study is especially devoted to the tilt grain boundaries in silicon as a model material. The theoretical model is based on the self-consistent tight-binding approximation and is applied within two numerical techniques: the fast 'order N' density-matrix method and the diagonalization technique which allows the sampling of the reciprocal space. Total energy parameters of the model have been fitted in order to reproduce the silicon band structure (with a correct gap value) and the transferability of crystalline and mechanical properties of this material. A new type of boundary conditions is proposed and tested. These conditions, named 'ante-periodic' or 'Moebius', allow only one grain boundary per box instead of two and decrease the CPU time by a factor of two. The model is then applied to the study of the {sigma}=25 [001] (710) grain boundary. The results show the possible presence in this boundary of low energy non-reconstructed atomic structures which are electrically active. This confirms what had been suggested by some experimental observations. The same study is also performed for the {sigma}=13 [001] (510) grain boundary. In order to compare the intrinsic electrical activity in the previous grain boundaries with the one induced by impurities, a total energy parametrization for the silicon-nickel bond is achieved and used in preliminary calculations. Finally the two variants of the {sigma}=11 [011] (2-33) interface are studied, especially their respective interfacial energies. The result disagrees with previous calculations using phenomenological potentials. (author)

    Tuesday, 4 October 2011 at 8:30 pm - This lecture recounts, step by step, discovery by discovery, the past 100 years of study of the nucleus.   2011 marks the 100th anniversary of Rutherford's discovery of the atomic nucleus. We are also celebrating the centenary of the award of the Nobel Prize for Chemistry to Marie Curie. These two events are intimately linked and mark the early years of a science that was to revolutionise physics and change the course of history. To achieve what they achieved, a good measure of luck was needed but, above all, hard work and genius. A tidal wave of technological innovations and conceptual revolutions from around 1911 gave birth to quantum mechanics and subsequently led to the discovery of the neutron, antimatter, artificial radioactivity and fission. Since the Second World War, discoveries have continued apace and the nucleus has been revealed in all its magical, deformed, rotating, and exotic glory. But even at the end of the 20th century, the nucleus ...

    This document reviews the theoretical and experimental achievements of the author concerning highly accurate atomic spectroscopy applied for the determination of fundamental constants. A pure optical frequency measurement of the 2S-12D 2-photon transitions in atomic hydrogen and deuterium has been performed. The experimental setting-up is described as well as the data analysis. Optimized values for the Rydberg constant and Lamb shifts have been deduced (R = 109737.31568516 (84) cm{sup -1}). An experiment devoted to the determination of the fine structure constant with an aimed relative uncertainty of 10{sup -9} began in 1999. This experiment is based on the fact that Bloch oscillations in a frequency chirped optical lattice are a powerful tool to transfer coherently many photon momenta to the atoms. We have used this method to measure accurately the ratio h/m(Rb). The measured value of the fine structure constant is {alpha}{sub -1} = 137.03599884 (91) with a relative uncertainty of 6.7*10{sup -9}. The future and perspectives of this experiment are presented. This document presented before an academic board will allow his author to manage research work and particularly to tutor thesis students. (A.C.)

    The SILVA enrichment process relies on the difference in the excitation frequencies of the electron transitions between uranium isotopes {sup 235}U and {sup 238}U. Light emitted by lasers can be tuned exactly to these frequencies, resulting in the selective excitation and ionization of the target isotope, namely isotope {sup 235}U. Subsequently, ions are separated from the {sup 238}U atoms by an electrical field and received on dedicated collectors Pr. In a SILVA plant, laser beams would have to propagate over a long distance in the work-medium, resulting in possible severe temporal and spatial beam distortions. Such effects may drastically reduce the efficiency of the photo-ionization and hence require close attention. Coupled Maxwell-Schroedinger equations describe changes in the material system as well as the temporal and spatial re-shaping of the laser pulses as they propagate through uranium vapour. This system of equations combines Maxwell's wave equation with Schroedinger quantum-mechanical description of field-matter interaction. However, the method suffers from a serious drawback: in the SILVA conditions, it leads to prohibitive computation times. In this context, this article presents an alternative formulation for the induced atomic polarization of an undamped two-level system obviating the need to solve the Schroedinger equation to describe, the propagation of a laser pulse in a near resonant atomic vapor. The method is based on the use of an intensity dependent index of refraction inferred from a quasi-adiabatic approximation. As an example, the final section of the paper discusses the complex time re-shaping undergone by a 5 ns near resonant (frequency shift D = 6 GHz) laser pulse as it propagates through an optically dense medium (N = 4.1013 at/cm{sup 3}). In this case, the quasi-adiabatic and Schroedinger models are shown to be in fairly good agreement.

    2005-12-15

    The studies done by Jean-Paul Crocombette between 1996 and 2005 in the Service de Recherches de Metallurgie Physique of the Direction de l'Energie Nucleaire in Saclay are presented in this Habilitation thesis. These works were part of the material science researches on the ageing, especially under irradiation, of oxides of interest for the nuclear industry. In this context simulation studies at the atomic scale were performed on two elementary components of ageing under irradiation : point defects and displacement cascades ; using two complementary simulation techniques : ab initio electronic structure calculations and empirical potential molecular dynamics. The first part deals with point defects : self defects (vacancies or interstitials) or hetero-atomic dopants. One first recalls the energetics of such defects in oxides, the specific features of defects calculations and the expected accuracy of these calculations. Then one presents the results obtained on uranium dioxide, oxygen in silver and amorphous silica. The second part tackles the modelling of disintegration recoil nuclei in various?displacement cascades created by crystalline matrices for actinide waste disposal. Cascade calculations give access to the amorphization mechanisms under irradiation of these materials. One thus predicts that the amorphization in zircon takes place directly in the tracks whereas in lanthanum zirconate, the amorphization proceeds through the accumulation of point defects. Finally the prospects of these studies are discussed. (author)

    2004-09-15

    The main purpose of this thesis is to get experimental data for the testing and validation of atomic physics codes dealing with non-local-thermodynamical-equilibrium plasmas. The first part is dedicated to the spectroscopic study of xenon and krypton plasmas that have been produced by a nanosecond laser pulse interacting with a gas jet. A Thomson scattering diagnostic has allowed us to measure independently plasma parameters such as electron temperature, electron density and the average ionisation state. We have obtained time integrated spectra in the range between 5 and 10 angstroms. We have identified about one hundred xenon rays between 8.6 and 9.6 angstroms via the use of the Relac code. We have discovered unknown rays for the krypton between 5.2 and 7.5 angstroms. In a second experiment we have extended the wavelength range to the X UV domain. The Averroes/Transpec code has been tested in the ranges from 9 to 15 angstroms and from 10 to 130 angstroms, the first range has been well reproduced while the second range requires a more complex data analysis. The second part is dedicated to the spectroscopic study of aluminium, selenium and samarium plasmas in femtosecond operating rate. We have designed an interferometry diagnostic in the frequency domain that has allowed us to measure the expanding speed of the target's backside. Via the use of an adequate isothermal model this parameter has led us to know the plasma electron temperature. Spectra and emission times of various rays from the aluminium and selenium plasmas have been computed satisfactorily with the Averroes/Transpec code coupled with Film and Multif hydrodynamical codes.

    1997-12-31

    Radiation damage by neutrons or ions in bcc iron has been investigated by molecular dynamics simulations using an embedded atom type many-body potential (EAM). Displacement cascades with energies of 1 to 30 keV were generated in the microcanonical system where the number of atoms (up to 1.5 million) is chosen high enough to compensate the fact that the dissipation of energy is not taken into account in our model. The defect number at the end of cascade lifetime was found to be 60 percent of the NRT standard value. This tendency is in good agreement with experimental data. However, compared with other simulations in iron, we found significant differences in the defect production and distribution. The comparison with results obtained form simulations of cascades in other metals, leads on the one hand to a higher value of the defect number in bcc iron than in fcc metals like copper or nickel, and on the other hand to a ratio, between the number of replacements and the number of defects, lower in iron ( 100). We observed the transient melting of the core of the cascade during simulations. We showed that a higher value of the initial iron crystal temperature, as the mass difference between the components of an artificial binary alloy Fe-X(X=Al,Sb,Au,U) both produce a `cascade effect`: a decrease of the number of defects and an increase of the number of replacements. We also showed up the quasi-channeling of some atoms in high energy cascades. They are at the origin of sub-cascades formation; as a result they induce an opposite effect to the `cascade effect`.

  7. Atom interferometry experiments with lithium. Accurate measurement of the electric polarizability; Experiences d'interferometrie atomique avec le lithium. Mesure de precision de la polarisabilite electrique

    2005-06-15

    Atom interferometers are very sensitive tools to make precise measurements of physical quantities. This study presents a measurement of the static electric polarizability of lithium by atom interferometry. Our result, {alpha} = (24.33 {+-} 0.16)*10{sup -30} m{sup 3}, improves by a factor 3 the most accurate measurements of this quantity. This work describes the tuning and the operation of a Mach-Zehnder atom interferometer in detail. The two interfering arms are separated by the elastic diffraction of the atomic wave by a laser standing wave, almost resonant with the first resonance transition of lithium atom. A set of experimental techniques, often complicated to implement, is necessary to build the experimental set-up. After a detailed study of the atom source (a supersonic beam of lithium seeded in argon), we present our experimental atom signals which exhibit a very high fringe visibility, up to 84.5 % for first order diffraction. A wide variety of signals has been observed by diffraction of the bosonic isotope at higher diffraction orders and by diffraction of the fermionic less abundant isotope. The quality of these signals is then used to do very accurate phase measurements. A first experiment investigates how the atom interferometer signals are modified by a magnetic field gradient. An absolute measurement of lithium atom electric polarizability is then achieved by applying a static electric field on one of the two interfering arms, separated by only 90 micrometers. The construction of such a capacitor, its alignment in the experimental set-up and its operation are fully detailed.We obtain a very accurate phase measurement of the induced Lo Surdo - Stark phase shift (0.07 % precision). For this first measurement, the final uncertainty on the electric polarizability of lithium is only 0.66 %, and is dominated by the uncertainty on the atom beam mean velocity, so that a further reduction of the uncertainty can be expected.

  8. Application of gel-Co-conversion for TRU (Pu, Np, Am) fuel and target preparation

    International Nuclear Information System (INIS)

    In the fabrication of fuel containing transuranium (TRU) elements, flow sheets and techniques which allow a shielded and/or remote fabrication will probably need to be applied. One approach, which has been demonstrated on the laboratory and semi prototype scale, is the wet fabrication route of coprecipitation of the matrix element uranium mixed with plutonium to form dense spherical particles or to produce hybrid pellets made from pressed gel microspheres. The ceramic material produced holds the TRU-elements homogeneously distributed in the matrix. In conjunction with the Departement d'Etudes des Combustibles of the French Commissariat a l'Energie Atomique (CEA-DEC) in Cadarache, the Paul Scherrer Institut (PSI) in Switzerland is further developing a mixed nitride ceramic and mixed oxide with high concentrations (up to 50%) of plutonium with the aim of a joint irradiation test of transuranium elements in the French PHENIX reactor. 6 refs., 3 figs., 3 tabs

    The threat posed by bioterrorism is a serious concern as the consequences of a large-scale biological attack would be devastating, causing significant social and economic disruption, while being potentially achievable at a relatively moderate cost and without the need for specific high-level technology. The biological agents potentially concerned include both microorganisms and protein toxins. In this Special Feature article, Eric Ezan and co-workers provide an up to date review and report on some of the technological developments that have recently enabled the detection of these bioagents to move forward. They also address today's challenges in translating MS-based approaches from the original environmental detection to clinical diagnosis. Dr. Ezan is a biochemist at the Centre d'Etude Atomique de Saclay (Gif sur Yvette, France). Amongst his research interests is the study of metabolic processing of biologics by numerous techniques including mass spectrometry. PMID:26956394

    In the fuel reprocessing industry, an un-baffled magnetic rod-stirred multiphase reactor was developed for a precipitation operation. The flow generated in such a reactor is complex and the rotating agitator at the bottom of tank creates a vortex on the liquid surface. A Computational Fluid Dynamics (CFD) modelling is developed based on a Large Eddy Scale (LES) approach for turbulence effect simulation. The numerical simulations are performed in 3-dimensions using the Trio-U code developed at the Commissariat a l'Energie Atomique (Cea). The vortex study is based on an interface tracking method and the rotating magnetic rod is taken into account through a free IBC immersed boundary. The hydrodynamic modelling is in good agreement with Nagata's theory and will be validated from experimental data obtained by laser doppler velocimetry (LDV) measurements. (authors)

    1986-01-01

    Fusion has a wide spectrum of applications that appear technically possible and may become economically feasible. Near-term (approx. 2000) application for production of nuclear fuels and useful radioisotopes is an economically attractive possibility as soon as fusion is ready. Electricity production will remain a prime, large-scale application of fusion. In the longer term, as fossil fuels dwindle, production of hydrogen could become a major application. Additional applications some of which have not even been conceived of yet, will add to this potential richness and diversity of fusion. It is the purpose of the fusion applications study - FMAE - to innovate, investigate, and evaluate these potential applications.

    Hochstadt, Jake

    2011-01-01

    Ruby on Rails is an open source web application framework for the Ruby programming language. The first application I built was a web application to manage and authenticate other applications. One of the main requirements for this application was a single sign-on service. This allowed authentication to be built in one location and be implemented in many different applications. For example, users would be able to login using their existing credentials, and be able to access other NASA applications without authenticating again. The second application I worked on was an internal qualification plan app. Previously, the viewing of employee qualifications was managed through Excel spread sheets. I built a database driven application to streamline the process of managing qualifications. Employees would be able to login securely to view, edit and update their personal qualifications.

    Optical coherence tomography (OCT), as an interferometric method, has been studied as a distance ranger. As a technology capable of producing high-resolution, depth-resolved images of biological tissue, OCT had been widely used for the application of ophthalmology and has been commercialized in the market today. Enlightened by the emerging research interest in biomedical domain, the applications of OCT in industrial inspection were rejuvenated by a few groups to explore its potential for characterizing new materials, imaging or inspecting industrial parts as a service solution[3]. Benefiting from novel photonics components and devices, the industrial application of the older concepts in OCT can be re-visited with respect to the unique performance and availability. Commercial OCT developers such as Michelson Diagnostics (MDL; Orpington, U.K.) and Thorlabs (Newton, NJ) are actively exploring the application of OCT to industrial applications and they have outlined meaningful path toward the metrology application in emerging industry[3]. In this chapter, we will introduce the fundamental concepts of OCT and discuss its current and potential industrial applications.

Some applications are already at industrial capacity, whereas others remain under development. In addition to extraction, application areas include impregnation and cleaning, multistage countercurrent separation, particle formation, coating, and reactive systems such as hydrogenation, biomass gasification, and supercritical water oxidation. Polymers are modified with supercritical fluids, and colloids and emulsions as well as nanostructured materials exhibit interesting phenomena when in contact with supercritical fluids that can be industrially exploited. For these applications to succeed, the properties of supercritical fluids in combination with the materials processed must be clearly determined and fundamental knowledge of the complex behavior must be made readily available.

    2011-01-01

    My project at KSC during my spring 2011 internship was to develop a Ruby on Rails application to manage Content Documents..A Content Document is a collection of documents and information that describes what software is installed on a Launch Control System Computer. It's important for us to make sure the tools we use everyday are secure, up-to-date, and properly licensed. Previously, keeping track of the information was done by Excel and Word files between different personnel. The goal of the new application is to be able to manage and access the Content Documents through a single database backed web application. Our LCS team will benefit greatly with this app. Admin's will be able to login securely to keep track and update the software installed on each computer in a timely manner. We also included exportability such as attaching additional documents that can be downloaded from the web application. The finished application will ease the process of managing Content Documents while streamlining the procedure. Ruby on Rails is a very powerful programming language and I am grateful to have the opportunity to build this application.

  8. Applications of radioluminescent lighting

    International Nuclear Information System (INIS)

    Glass-tube radioluminescent (RL) systems have been demonstrated as attractive alternatives to electrically powered airfield marking and lighting systems for remote airfields, rapid runway repair, and other airfield lighting and marking uses. Individual light units for RL systems are self-powered, reliable, easily maintained and deployed, and can be made to produce infrared or visible light. Tests and demonstrations of prototype light units conducted by the US Dept. of Energy's RL Lights Program in recent years for the Air Force, Navy, Army, and Marine Corps and for Florida and Alaska have proved the basic technological worth of RL airfield lighting systems for civilian and military use. The technology has advanced to a point where other military and civilian applications can now be considered. Military applications include emergency degree, damage control, cargo marking, low-level lighting for work areas and other unique uses. Civilian applications include marine navigational aids, roadway marking, emergency escape lighting, lighting for telephone conduit tunnels, and other applications where access to electrical power is limited or difficult to supply or maintain. Isotope options for these applications are shown. Research is expected to produced advanced RL light systems within the next several years

    Full Text Available Carbon nanotubes (CNTs are a fascinating subject for curiosity-driven research. But will they give rise to commercially viable applications? CNTs are rolled up sheets of sp2; bonded graphite with no surface broken bonds. Their possible applications1,2; arise from the remarkable properties of single-walled nanotubes (SWNTs such as the highest Young's modulus, highest thermal conductivity, ballistic electron transport, and high aspect ratio structure. To date, development of nanotube-based products has been delayed by a lack of availability of quantities of material and lack of control of their growth. Supplies of multi-walled nanotubes (MWNTs or nanofibers have been available from Hyperion Catalysis International, but under constraint and only as preformed composites. The supply situation is now improving with several firms producing on a larger scale, such as CNI, Showa Denko, Thomas Swan, and Nanocyl. Now is, therefore, a good time to look at applications from a more business view.

    Fischer, N; Tarasow, T; Tok, J

    2007-01-03

    Nucleic acid aptamers have found steadily increased utility and application steadily over the last decade. In particular, aptamers have been touted as a valuable complement to and in some cases replacement for antibodies due to their structural and functional robustness as well as their ease in generation and synthesis. They are thus attractive for biosecurity applications, e.g. pathogen detection, and are especially well suited since their in vitro generation process does not require infection of any host systems. Herein we provide a brief overview of the aptamers generated against biopathogens over the last few years. In addition, a few recently described detection platforms using aptamers (aptasensors) and potentially suitable for biosecurity applications will be discussed.

  3. Medical applications of holography

    Science.gov (United States)

    von Bally, Gert

    1991-11-01

    From the various capabilities of holography for image processing and measuring purposes, holographic interferometric techniques have found more extended application in biological and medical research. Due to their special properties the different methods of holographic interferometry are applied to characteristic fields of biomedical investigations where--similar to nondestructive testing--vibration and deformation analysis is of interest. Features of holographic interferometry, such as the possibility of noncontactive, three-dimensional investigations with a large field-of-depth, are used with advantage. The main applications can be found in basic research e.g., in audiology, dentistry, opthalmology, and experimental orthopedics. Because of the great number of investigations and the variety of medical domains in which these investigations were performed this survey is confined to some characteristic examples. As in all fields of optics and laser metrology, a review on biomedical applications of holography would be incomplete if military developments and utilization were not mentioned. As demonstrated by selected examples, the increasing interlacing of science with the military does not stop at domains that traditionally are regarded as exclusively oriented to human welfare--like biomedical research. The term ''Star Wars Medicine'', which becomes an increasingly popular expression for laser applications (including holography) in medicine, characterizes the consequences of this development.

    The Atmospheric Infrared Sounder (AIRS) on NASA's Aqua spacecraft has been returning daily global observations of Earth's atmospheric constituents and properties since 2002. With a 12-year data record and daily, global observations in near real-time, AIRS data can play a role in applications that fall under many of the NASA Applied Sciences focus areas. For vector-borne disease, research is underway using AIRS near surface retrievals to assess outbreak risk, mosquito incubation periods and epidemic potential for dengue fever, malaria, and West Nile virus. For drought applications, AIRS temperature and humidity data are being used in the development of new drought indicators and improvement in the understanding of drought development. For volcanic hazards, new algorithms using AIRS data are in development to improve the reporting of sulfur dioxide concentration, the burden and height of volcanic ash and dust, all of which pose a safety threat to aircraft. In addition, anomaly maps of many of AIRS standard products are being produced to help highlight "hot spots" and illustrate trends. To distribute it's applications imagery, AIRS is leveraging existing NASA data frameworks and organizations to facilitate archiving, distribution and participation in the BEDI. This poster will communicate the status of the applications effort for the AIRS Project and provide examples of new maps designed to best communicate the AIRS data.

    Full Text Available Abstract Background Sequence similarity searching is a very important bioinformatics task. While Basic Local Alignment Search Tool (BLAST outperforms exact methods through its use of heuristics, the speed of the current BLAST software is suboptimal for very long queries or database sequences. There are also some shortcomings in the user-interface of the current command-line applications. Results We describe features and improvements of rewritten BLAST software and introduce new command-line applications. Long query sequences are broken into chunks for processing, in some cases leading to dramatically shorter run times. For long database sequences, it is possible to retrieve only the relevant parts of the sequence, reducing CPU time and memory usage for searches of short queries against databases of contigs or chromosomes. The program can now retrieve masking information for database sequences from the BLAST databases. A new modular software library can now access subject sequence data from arbitrary data sources. We introduce several new features, including strategy files that allow a user to save and reuse their favorite set of options. The strategy files can be uploaded to and downloaded from the NCBI BLAST web site. Conclusion The new BLAST command-line applications, compared to the current BLAST tools, demonstrate substantial speed improvements for long queries as well as chromosome length database sequences. We have also improved the user interface of the command-line applications.

    The article entitled "Novel Biocatalysts Will Work Even Better for Industry" published recently in this Journal (1) was informative and interesting. However it touched only briefly on the application of peroxidase as catalyst. Here, we would like to mention in more detail the novel applications of peroxidase in agricultural, paper pulp, water treatment, pharmaceutical, and medical situations. Firstly, the peroxidase isolated from Phanerochaete chyrosporium has been shown to detoxify herbicides such as atrazine to less toxic compounds and would certainly find potential application in agriculture (2). Secondly, the peroxidase produced by Streptomyces thermoviolaceus may find application in the paper pulp industry as a delignifying agent (3). Thirdly, it has been shown that extracellular peroxidase produced by Streptomyces avermitilis can remove the intense color from paper-mill effluent obtained after semichemical alkaline pulping of wheat straw (4), and thus this enzyme might find application as a catalyst in water treatment plants. Fourthly, the heme-containing horseradish peroxidase enzyme has been exploited in several diagnostic applications in pharmaceutics and medicine, such as the detection of human immunodeficiency virus and cystic fibrosis (5-10). Finally, recent work from our laboratory has suggested that thermophilic nonheme peroxidase produced by Thermomonospora fusca BD25 may find medical use in the diagnosis of myocardial infarction (11, 12).

  9. Magnetoplasmadynamic thruster applications

    International Nuclear Information System (INIS)

    Advance study activities within NASA indicate that electric propulsion will be required to make certain types of potential missions feasible. The large power levels under consideration make magnetoplasmadynamic thrusters a good candidate for these applications since this type of electric thruster is best suited to operation at high power levels. The status of the magnetoplasmadynamic thruster is examined and compared to the ion thruster which also is a candidate. The use of these two types of electric propulsion devices for orbit raising of a self-powered large satellite is examined from a cost standpoint. In addition the use of nuclear electric propulsion is described for use as both a near-earth space tug and for an interplanetary exploration vehicle. These preliminary examinations indicate that the magnetoplasmadynamic thruster is the lowest cost thruster and therefore merits serious consideration for these applications

  10. Cogeneration and trigeneration applications

    International Nuclear Information System (INIS)

    Combined heat and power cogeneration, or ''autoproduction'' as it is known in Turkey, is the simultaneous production of heat and electricity, while trigeneration includes the cold production in addition to cogeneration. This technology has been advanced by governmental support and the continuing need for additional electricity generation within Turkey. The present study deals with cogeneration and trigeneration applications in Turkey, giving the electricity market development. Only four cogeneration plants with a total capacity of 30 MW e were operated up to 1994, while trigeneration applications have started for the last two years. The total installed cogeneration capacity is expected to reach up to 6,000 MWe by 2005, which would represent about 20% of Turkey's total installed electricity generating capacity. In this context, cogeneration and trigeneration have had, or will have, a significant and increasing role in dictating the energy strategies for Turkey. (Author)

    The graph is a critical and useful concept in designing many information processing systems. Systems such as transaction processing systems, decision support systems, and workflow systems are all helped immensely by a graphical structure. Simple graphs and digraphs allow for the construction of a variety of system design tools that provide a convenient and appealing format for illustrating information infrastructures, while allowing any subsequent analyses to be performed by the user. However, the metagraph, a new graphical structure that is developed in this book, goes beyond the representational and provides Information Systems with a robust, analytical modeling graphic tool. METAGRAPHS AND THEIR APPLICATIONS is a presentation of metagraph theory and its applications that begins by defining a metagraph and its uses. They are more complex than a simple graph structure, but they allow for representation and analysis of more complex systems. The material contained in this book is presented in two parts. The fi...

  18. Justification: theory and application

    International Nuclear Information System (INIS)

    The concept of justification implies that a specific decision as to the relative merits of benefits and costs and detriment be made whenever: (1) a new practice is introduced that involves an indirect or direct increase in radiation exposure; or (2) an existing practice affecting radiation exposure is modified; or (3) an increase in radiation protection of an existing practice is to be considered. Such decisions are imprecise and involve intangible values. ICRP has, however, developed a mathematical model to express the structure of such decisions. The utility of this model for making the key paramters of justification decisions visible is explored in this paper in two ways. First, the structure of the model and its implications are explored in the abstract. Secondly, several specific applications are studied to determine if the model has utility in structuring application decisions, and the extent to which conclusions can be evolved in a meaningful, visible manner.

  19. Applications of optical imaging

    International Nuclear Information System (INIS)

    Optical imaging in the form of near infrared fluorescence and bioluminescence has proven useful for a wide range of applications in the field of molecular imaging. Both techniques provide a high sensitivity (in the nanomolar range), which is of particular importance for molecular imaging. Imaging with near infrared fluorescence is especially cost-effective and can be performed, in contrast to radioactivity-based methods, with fluorescence dyes that remain stable for months. The most important advantage of bioluminescence, in turn, is the lack of background signal. Although molecular imaging with these techniques is still in the experimental phase, an application of near infrared fluorescence is already foreseeable for the imaging of superficial structures.

    Bucur, Claudia

    2016-01-01

    Working in the fractional Laplace framework, this book provides models and theorems related to nonlocal diffusion phenomena. In addition to a simple probabilistic interpretation, some applications to water waves, crystal dislocations, nonlocal phase transitions, nonlocal minimal surfaces and Schrödinger equations are given. Furthermore, an example of an s-harmonic function, its harmonic extension and some insight into a fractional version of a classical conjecture due to De Giorgi are presented. Although the aim is primarily to gather some introductory material concerning applications of the fractional Laplacian, some of the proofs and results are new. The work is entirely self-contained, and readers who wish to pursue related subjects of interest are invited to consult the rich bibliography for guidance.

    Tuchin, Valery V; Zimnyakov, Dmitry A

    2006-01-01

    Optical Polarization in Biomedical Applications introduces key developments in optical polarization methods for quantitative studies of tissues, while presenting the theory of polarization transfer in a random medium as a basis for the quantitative description of polarized light interaction with tissues. This theory uses the modified transfer equation for Stokes parameters and predicts the polarization structure of multiple scattered optical fields. The backscattering polarization matrices (Jones matrix and Mueller matrix) important for noninvasive medical diagnostic are introduced. The text also describes a number of diagnostic techniques such as CW polarization imaging and spectroscopy, polarization microscopy and cytometry. As a new tool for medical diagnosis, optical coherent polarization tomography is analyzed. The monograph also covers a range of biomedical applications, among them cataract and glaucoma diagnostics, glucose sensing, and the detection of bacteria.

    The design and practical applications of excilamps having a dielectric barrier and capacitive structure and driven by nanosecond, high voltage pulses are described. A simple design lamp having forced cooling and an excitation generator was demonstrated to have a lifetime of more than one thousand hours. The results of an experimental study of capacitive and high voltage nanosecond discharge-driven excilamps are presented. The influence of the excitation regime and operating gas mixture pressure on the dielectric barrier discharge (DBD) driven excilamps' efficiency is discussed. The discharge formation and output radiation dynamics of DBD driven excilamps was experimentally studied for the first time. The practical applications of several lamps designed in the High Current Electronics Institute, Tomsk, Russia to photochemistry, photobiology and photomedicine are discussed.

  3. Diverse applications of radioimmunoassay

    International Nuclear Information System (INIS)

    The author discussed the issues concerning insulins of the different species (pig, dog and sperm whale) and the applications of species specific antisera in experimental and clinical settings. The possible role of a new form of ACTH as a hormonal marker was also discussed. Three species of insulin (pig, dog, and sperm whale) were separated by human antisera. Immune reaction was utilized to distinguish between endogenous human insulin and exogenously administered animal insulin. The longer acting insulins was found to be more immunogenic than regular crystalline insulins. Insulin concentrations in acid/ethanol extracts of the whole rat brain was about 25 times higher than plasma insulin. Plasma concentration of ACTH could be applicable to effect the distinction between tumor primary in or metastatic to the lung. (Nakanishi, T.)

    Full Text Available This paper deals with the issue of a long time research concerning the representation of complex surfaces in descriptive geometry. The ability to use the different techniques of representation aims to achieve results never thought before. In the University of Palermo, at the Engineering School, the research involved the study on simplifying a more elaborated way to represent the geometry and its applications in buildings architecture and related engineering plants and equipment. Specifically, is here reported the application of the proposed method to represent one of the most used surfaces in the buildings design. It concerns a helicoid surface represented in orthogonal axonometric projecting. The method is essentially based on the experimental homology that, by the way, is extensively documented in the bibliography section of this paper.

  6. Nanotechnology applications in osteodistraction

    2014-06-01

    Full Text Available Most current strategies for bone regeneration have relatively satisfactory results. However, there are drawbacks and limitations associated with their use and availability, and even controversial reports about their efficacy and cost-effectiveness. The induction of new bone formation through distraction osteogenesis (DO is widespread clinical application in the treatment of bone defects, limb deformities, and fracture nonunions. However, a lengthy period of external fixation is usually needed to allow the new bone to consolidate, and complications such as refracture at the distraction gap often occur. Although various biomaterials have been used as injectable delivery systems in DO models, little has been reported on the use of nanobiomaterials as carrier materials for the sustained release of growth factors in bone regeneration. One area of focus in nanotechnology is the delivery of osteogenic factors in an attempt to modulate the formation of bone. This review article seeks to demonstrate the potential of nanobiomaterials to improve biological applications pertinent to osteodistraction.

    As pointed out in the introduction of Part 1, the isolation strategy can be used to effectively decouple a structure from its environment and thus the structure can be protected from damaging seismic loads or unwanted vibrations and noises from the environment. The method has been used for solving vibration and shock problems in machinery and equipment for many years, but its application to the protection of structures from seismic loadings is relatively recent. Owing to the current interest generated by the Northridge and Kobe earthquakes, all but one of the papers in this publication deal with seismic isolation.

    International Nuclear Information System (INIS)

    Nano technology is the engineering of functional systems at the molecular scale. This covers both works and concepts that are more advanced. In its original sense, nano technology refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete high performance products. Development of applications incorporating semiconductor nanoparticles to be used in the next generation of products, such as display technology, lighting, solar cells and biological imaging and others are widely progressives. Progress has been made in using medical applications (Nano medicine) which provided the possibility of delivering drugs to specific cells using nanoparticles. Otherwise, nanoparticles have high surface area to volume ratio, allowing many functional groups to be attached to a nanoparticle, which can seek out and bind to certain tumor cells (cancer).

  14. Industrial applications at GANIL

    International Nuclear Information System (INIS)

    After a first round of industrial applications using heavy ion beams, GANIL has refocused these activities along the lines defined by a strategy and market study. Heavy ion industrial applications take their roots in the physical effects of the interactions occurring between heavy ion projectiles and matter. Specific equipments operated by GANIL or CIRIL allow users to take benefit from these effects. By heavy ion irradiation, industrial companies qualify radiation hardened electronic components and sensitize plastic films to produce 'nuclear track' membranes. Research and development programs with laboratories of the public sector, focus on heavy ion lithography dedicated to large area luminescent flat screens with field emitter microtips and on tribology with radioactive implanted ions. Even sometimes facing difficulties to fill the gap between industry and research, GANIL is eager to promote heavy ion beam technologies. (author) 36 refs., 6 figs., 5 tabs

  15. Nuclear applications for health

    International Nuclear Information System (INIS)

    Just before the turn of the 20th century, the discoveries of X-rays, in 1895, and of radioactivity, in 1896, opened up whole new worlds of science. For the medical community, the world has been changing ever since, in some countries far more rapidly than in others. Over the past 100 years, the X-ray has become as familiar to most people as the dentist's chair. As we move into the next century, greater attention is being placed upon less known but more far-reaching radiation technologies and nuclear applications that today's physicians are able to use for earlier diagnosis and treatment of serious illness. This article, in question-and-answer format, explains the differences between the various types of nuclear applications for human health and looks at the evolution of the IAEA's related activities.

  17. Clinical Applications for Estetrol

    Directory of Open Access Journals (Sweden)

    Visser M

    2010-01-01

    Full Text Available In this paper the potential clinical applications for the human fetal estrogen estetrol (E4 are presented based on recently obtained data in preclinical and clinical studies. In the past E4 has been classified as a weak estrogen due to its rather low estrogen receptor affinity. However, recent research has demonstrated that due to its favorable pharmacokinetic properties, especially the slow elimination and long half-life, E4 is an effective orally bioavailable estrogen agonist with estrogen antagonistic effects on the breast in the presence of estradiol. Based on the pharmacokinetic properties, the pharmacological profile and the safety and efficacy results in human studies, E4 seems potentially suitable as a drug for human use in applications such as hormone replacement therapy (vaginal atrophy and vasomotor symptoms, contraception, osteoporosis and breast cancer.

    CERN Document Server

    Assi, Abdallah

    2016-01-01

    This work presents applications of numerical semigroups in Algebraic Geometry, Number Theory, and Coding Theory. Background on numerical semigroups is presented in the first two chapters, which introduce basic notation and fundamental concepts and irreducible numerical semigroups. The focus is in particular on free semigroups, which are irreducible; semigroups associated with planar curves are of this kind. The authors also introduce semigroups associated with irreducible meromorphic series, and show how these are used in order to present the properties of planar curves. Invariants of non-unique factorizations for numerical semigroups are also studied. These invariants are computationally accessible in this setting, and thus this monograph can be used as an introduction to Factorization Theory. Since factorizations and divisibility are strongly connected, the authors show some applications to AG Codes in the final section. The book will be of value for undergraduate students (especially those at a higher leve...

    CERN Document Server

    Kaur, Inderjeet

    1983-01-01

    Two-dimensional materials created ab initio by the process of condensation of atoms, molecules, or ions, called thin films, have unique properties significantly different from the corresponding bulk materials as a result of their physical dimensions, geometry, nonequilibrium microstructure, and metallurgy. Further, these characteristic features of thin films can be drasti­ cally modified and tailored to obtain the desired and required physical characteristics. These features form the basis of development of a host of extraordinary active and passive thin film device applications in the last two decades. On the one extreme, these applications are in the submicron dimensions in such areas as very large scale integration (VLSI), Josephson junction quantum interference devices, magnetic bubbles, and integrated optics. On the other extreme, large-area thin films are being used as selective coatings for solar thermal conversion, solar cells for photovoltaic conver­ sion, and protection and passivating layers.

  16. Overview of SMR applications

    International Nuclear Information System (INIS)

    Energy demand will continue to grow worldwide, with a faster growth in developing countries; consequently a wide range of options needs to be maintained for energy production and utilization in order to achieve environmental and economic objectives. This paper describes the various possibilities of non-electric applications of nuclear energy The temperature requirements for these applications vary greatly from low temperature heat for district heating and desalination to high temperature process heat for coal gasification and hydrogen production. Processes requiring temperatures of up to 300 deg. C can be supplied by water-cooled reactors while breeders may be applied to processes requiring up to 540 deg. C. The high temperature gas cooled reactor can provide process heat temperatures of 950 deg. C. Thus, nuclear energy has the potential to provide heat for many of the world's industrial heat application processes. Small and medium sized reactors are more suited for this purpose because of their reduced output capacity and grid size requirement. The attractiveness of using nuclear energy for non-electric applications, compared to fossil energy is the long-term stability of nuclear fuel prices in contrast to the rising prices of fossil fuels, increase of energy independence, decrease of the environmental impact and contribution to national technology and manpower development. The technical viability of employing nuclear heat sources for district heating or for industrial processes has existed since the very start of nuclear development. A substantial penetration into the commercial heat market, however, has not yet taken place. The prospects for the future will depend on where and how the demand characteristics of the heat market can be matched by what nuclear reactors are able to offer. (author)

  4. Radioisotopes for medical applications

    International Nuclear Information System (INIS)

    For more than 3 decades, the Australian Nuclear Science and Technology Organisation has been the country's main supplier of radioisotopes for medical applications. The use of radioisotopes in medicine has revolutionised the diagnosis, management and treatment of many serious diseases such as cancer, heart disease and stroke. It is also beginning to play a key role in neurological disorders such as Parkinson and Alzheimers disease and epilepsy. More recently there has been considerable growth in the application of nuclear medicine to treat sport-related injuries - especially wrist, ankle and knees where more common techniques do not always enable accurate diagnosis. Australia is a recognised leader in nuclear medicine. This can be partially attributed to the close relationship between ANSTO and the medical community in providing opportunities to develop and evaluate new agents to support more effective patient care. A list of commercial isotopes produced in the reactor or the cyclotron and used in medical applications is given. Nuclear medicine plays an important role in the clinical environment and the timely supply of radioisotopes is a key element. ANSTO will continue to be the premier supplier of currently available and developing isotopes to support the health and well being of the Australian community

  5. Load Balancing Scientific Applications

    Energy Technology Data Exchange (ETDEWEB)

    Pearce, Olga Tkachyshyn [Texas A & M Univ., College Station, TX (United States)

    2014-12-01

    The largest supercomputers have millions of independent processors, and concurrency levels are rapidly increasing. For ideal efficiency, developers of the simulations that run on these machines must ensure that computational work is evenly balanced among processors. Assigning work evenly is challenging because many large modern parallel codes simulate behavior of physical systems that evolve over time, and their workloads change over time. Furthermore, the cost of imbalanced load increases with scale because most large-scale scientific simulations today use a Single Program Multiple Data (SPMD) parallel programming model, and an increasing number of processors will wait for the slowest one at the synchronization points. To address load imbalance, many large-scale parallel applications use dynamic load balance algorithms to redistribute work evenly. The research objective of this dissertation is to develop methods to decide when and how to load balance the application, and to balance it effectively and affordably. We measure and evaluate the computational load of the application, and develop strategies to decide when and how to correct the imbalance. Depending on the simulation, a fast, local load balance algorithm may be suitable, or a more sophisticated and expensive algorithm may be required. We developed a model for comparison of load balance algorithms for a specific state of the simulation that enables the selection of a balancing algorithm that will minimize overall runtime.

  6. Stable isotope applications

    International Nuclear Information System (INIS)

    The following domains of stable isotope applications are presented: - isotope dilution analyses as in trace analyses or volume and mass determinations; - stable isotopes as tracers as applied in environmental studies, agricultural research, products and objects authentification, transport phenomena, reaction mechanisms, determinations of structure and complex biological function, metabolism studies, diagnostic respiration tests, positron emission tomography; - equilibrium isotopic effects as investigated in measurements of effects, studies of equilibrium conditions, the mechanism of drug action, study of natural processes, water circuit, temperature measurements; - kinetic isotopic effects, as, for instance, reaction rates and mechanisms, solvent isotopic effects; - stable isotopes for advanced nuclear reactors as, for instance, uranium nitride with 15 N as nuclear fuel or 157 Gd for reactivity control. In spite of the difficulties regarding stable isotope use and first of all, of the difficult and costly analytical techniques, a continuous growth of the number of stable isotope applications in different fields is registered. The number of works and scientific meetings on the subject, as organized by the International Society of Isotopes and IAEA-Vienna, Gordon Conferences, regional meetings in Germany, France, etc. increase continuously. Development of the stable isotope application on a larger scale requires improving both their production technologies as well as those of labelled substances and, at the same time, the analytical methods

  7. Therapeutic applications of radiopharmaceuticals

    International Nuclear Information System (INIS)

    Whether a radiopharmaceutical has diagnostic or therapeutic application depends on both the isotope and pharmaceutical used. For diagnostic applications, the isotope should undergo only γ-decay, since usually only γ-radiation is detected by nuclear medicine cameras. The half-life should be just long enough to allow the procedure to be performed. In contrast, the isotope needed for therapeutic purposes should have particulate radiation, such as a β-particle (electron), since these are locally absorbed an increase the local radiation dose. γ-Radiation, which penetrates the tissues, produces less radiation dose than do Β-particles. Several references dealing with radioactive decay, particulate interactions, and diagnostic and therapeutic applications of radiopharmaceuticals are available. Radiopharmaceuticals can legally be used only by physicians who are qualified by specific training in the safe handling of radionuclides. The experience and training of these physicians must be approved by the Nuclear Regulatory Commission or Agreement State Agency authorized to license the use of radiopharmaceuticals. A list of all byproduct material and procedures is available in the Code of Federal Regulations. Of the many radiopharmaceuticals available for diagnostic and therapeutic use, only those commonly used are discussed in this chapter

    2013-10-31

    In FY13, Pacific Northwest National Laboratory (PNNL) with funding from the Department of Energy’s (DOE’s) Building Technologies Office (BTO) designed, prototyped and tested a transactional network platform to support energy, operational and financial transactions between any networked entities (equipment, organizations, buildings, grid, etc.). Initially, in FY13, the concept demonstrated transactions between packaged rooftop air conditioners and heat pump units (RTUs) and the electric grid using applications or "agents" that reside on the platform, on the equipment, on a local building controller or in the Cloud. The transactional network project is a multi-lab effort with Oakridge National Laboratory (ORNL) and Lawrence Berkeley National Laboratory (LBNL) also contributing to the effort. PNNL coordinated the project and also was responsible for the development of the transactional network (TN) platform and three different applications associated with RTUs. This document describes two applications or "agents" in details, and also summarizes the platform. The TN platform details are described in another companion document.

    This report examines the market potential of a miniature, hand-held Ion Mobility Spectrometer. Military and civilian markets are discussed, as well as applications in a variety of diverse fields. The strengths and weaknesses of competing technologies are discussed. An extensive Ion Mobility Spectrometry (IMS) bibliography is included. The conclusions drawn from this study are: (1) There are a number of competing technologies that are capable of detecting explosives, drugs, biological, or chemical agents. The IMS system currently represents the best available compromise regarding sensitivity, specificity, and portability. (2) The military market is not as large as the commercial market, but the military services are more likely to invest R and D funds in the system. (3) Military applications should be addressed before commercial applications are addressed. (4) There is potentially a large commercial market for rugged, hand-held Ion Mobility Spectrometer systems. Commercial users typically do not invest R and D funds in this type of equipment rather, they wait for off-the-shelf availability.

  10. Electrospinning and its applications

    Park, Jun-Seo

    2010-12-01

    Electrospinning is a process used to fabricate continuous nanoscale fibers with diameters in the sub-micrometer to nanometer range using a high-voltage power supply. Electrospun (e-spun) fibers and the non-woven webs manufactured from them have attracted considerable attention due to their outstanding characteristics, such as high porosity, small diameter, excellent pore interconnectivity and high surface-to-volume ratio. Because of the useful properties of e-spun fibers, many synthetic and natural polymers, including single and blended polymers, have been electrospun into fibers that can be employed in a variety of applications such as filtration and thermal insulation, and in the manufacture of protective clothing, sensors, conducting devices, wound dressings and scaffolds for tissue engineering. Utilizing the electrospinning technique and its product, some studies on its applications have been conducted in our lab. They included the fabrication of a conducting composite mat for electrical applications, an antibacterial web for a biomedical sector and PCM containing e-spun mat for energy storage.

  15. Incineration process for chlorinated alpha-contaminated wastes: industrial application to the Valduc project

    International Nuclear Information System (INIS)

    The Commissariat a l'Energie Atomique (CEA) has pursued a broad research and development program for a number of years concerning the incineration of chlorinated α-contaminated wastes produced by work in confined atmosphere. This program has now reached the stage where an alternative solution is available to the conventional direct cement embedding method currently used for such wastes. The proposed solution is based on a two-step incineration process offering a significant volume reduction that constitutes a serious economic advantage for geological disposal. Moreover, the process produces ashes of a quality suitable for direct online vitrification, or for Pu recovery by dissolution with silver II. The process was developed under nonradioactive conditions in the IRIS incineration pilot facility operated by the CEA's Fuel Cycle Division (CEA/DCC), opening the way for the first industrial facility, planned for the VALDUC Research Center. USSI is the prime contractor in this 36-month project. The basic design work has now been completed, and the French safety authorities have authorized construction of the incinerator, based in large part on the experience and expertise acquired by the process licenser CEA/DCC.

  16. Application of the variable incident angle method for PIXE and Pige in the field of arrhythmic

    International Nuclear Information System (INIS)

    For several years PIGE (particle induced gamma-ray emission) and PIXE(particle induced X-ray emission) have been considered as very suitable methods in the field of archaeometry. In fact these techniques, used under atmospheric pressure, are sensitive, multielemental and above all nondestructive. However both suffer from the same disadvantage: the information coming from the different part of the charged particle path is integrated and the inhomogeneities of the sample are not taken into account. The present paper shows how the use of several measurements at different incident angle could give an answer to this problem. The incident angle variation allows to investigate the material at different depths and then, either to distinguish between the elements belonging to the successive layers or even to deduce the concentration gradient. Several examples are given for PIXE in the case of multilayered painting, the measurements qualitatively show the stratigraphy and then allow to detect over painting or to understand how the artist has proceeded to obtain some special effects. For PIGE, the possibility to measure the evolution of the sodium concentration in the depth of ancient glasses allows to obtain information about the corrosion status. For achieving this work, the CGRMEV AVF cyclotron and the atmospheric PIGE-PIXE set-up of the (Institut de Physique Nucleare et Atomique et de Spectroscopy) have been used

  17. WAP - based telemedicine applications

    International Nuclear Information System (INIS)

    Telemedicine refers to the utilization of telecommunication technology for medical diagnosis, treatment, and patient care. Its aim is to provide expert-based health care to remote sites through telecommunication and information technologies. The significant advances in technologies have enabled the introduction of a broad range of telemedicine applications, which are supported by computer networks, wireless communication, and information superhighway. For example, some hospitals are using tele-radiology for remote consultation. Such a system includes medical imaging devices networked with computers and databases. Another growing area is patient monitoring, in which sensors are used to acquire biomedical signals, such as electrocardiogram (ECG), blood pressure, and body temperature, from a remote patient, who could be in bed or moving freely. The signals are then relayed to remote systems for viewing and analysis. Telemedicine can be divided into two basic modes of operations: real-time mode, in which the patient data can be accessed remotely in real-time, and store-and-forward mode, in which the acquired data does not have to be accessed immediately. In the recent years, many parties have demonstrated various telemedicine applications based on the Internet and cellular phone as these two fields have been developing rapidly. A current, recognizable trend in telecommunication is the convergence of wireless communication and computer network technologies. This has been reflected in recently developed telemedicine systems. For example, in 1998 J. Reponen, et al. have demonstrated transmission and display of computerized tomography (CT) examinations using a remote portable computer wirelessly connected to a computer network through TCP/IP on a GSM cellular phone. Two years later, they carried out the same tests with a GSM-based wireless personal digital assistant (PDA). The WAP (Wireless Application Protocol) Forum was founded in 1997 to create a global protocol

  12. Applications of Research Reactors

    International Nuclear Information System (INIS)

    One of the IAEA's statutory objectives is to 'seek to accelerate and enlarge the contribution of atomic energy to peace, health and prosperity throughout the world.' One way this objective is achieved is through the publication of a range of technical series. Two of these are the IAEA Nuclear Energy Series and the IAEA Safety Standards Series. According to Article III.A.6 of the IAEA Statute, the safety standards establish 'standards of safety for protection of health and minimization of danger to life and property'. The safety standards include the Safety Fundamentals, Safety Requirements and Safety Guides. These standards are written primarily in a regulatory style, and are binding on the IAEA for its own programmes. The principal users are the regulatory bodies in Member States and other national authorities. The IAEA Nuclear Energy Series comprises reports designed to encourage and assist R and D on, and application of, nuclear energy for peaceful uses. This includes practical examples to be used by owners and operators of utilities in Member States, implementing organizations, academia, and government officials, among others. This information is presented in guides, reports on technology status and advances, and best practices for peaceful uses of nuclear energy based on inputs from international experts. The IAEA Nuclear Energy Series complements the IAEA Safety Standards Series. The purpose of the earlier publication, The Application of Research Reactors, IAEA-TECDOC-1234, was to present descriptions of the typical forms of research reactor use. The necessary criteria to enable an application to be performed were outlined for each one, and, in many cases, the minimum as well as the desirable requirements were given. This revision of the publication over a decade later maintains the original purpose and now specifically takes into account the changes in service requirements demanded by the relevant stakeholders. In particular, the significant improvements in

    Nisin is a bacteriocin produced by a group of Gram-positive bacteria that belongs to Lactococcus and Streptococcus species. Nisin is classified as a Type A (I) lantibiotic that is synthesized from mRNA and the translated peptide contains several unusual amino acids due to post-translational modifications. Over the past few decades, nisin has been used widely as a food biopreservative. Since then, many natural and genetically modified variants of nisin have been identified and studied for their unique antimicrobial properties. Nisin is FDA approved and generally regarded as a safe peptide with recognized potential for clinical use. Over the past two decades the application of nisin has been extended to biomedical fields. Studies have reported that nisin can prevent the growth of drug-resistant bacterial strains, such as methicillin-resistant Staphylococcus aureus, Streptococcus pneumoniae, Enterococci and Clostridium difficile. Nisin has now been shown to have antimicrobial activity against both Gram-positive and Gram-negative disease-associated pathogens. Nisin has been reported to have anti-biofilm properties and can work synergistically in combination with conventional therapeutic drugs. In addition, like host-defence peptides, nisin may activate the adaptive immune response and have an immunomodulatory role. Increasing evidence indicates that nisin can influence the growth of tumours and exhibit selective cytotoxicity towards cancer cells. Collectively, the application of nisin has advanced beyond its role as a food biopreservative. Thus, this review will describe and compare studies on nisin and provide insight into its future biomedical applications. PMID:26678028

  14. Factsheets Web Application

    Energy Technology Data Exchange (ETDEWEB)

    VIGIL,FRANK; REEDER,ROXANA G.

    2000-10-30

    The Factsheets web application was conceived out of the requirement to create, update, publish, and maintain a web site with dynamic research and development (R and D) content. Before creating the site, a requirements discovery process was done in order to accurately capture the purpose and functionality of the site. One of the high priority requirements for the site would be that no specialized training in web page authoring would be necessary. All functions of uploading, creation, and editing of factsheets needed to be accomplished by entering data directly into web form screens generated by the application. Another important requirement of the site was to allow for access to the factsheet web pages and data via the internal Sandia Restricted Network and Sandia Open Network based on the status of the input data. Important to the owners of the web site would be to allow the published factsheets to be accessible to all personnel within the department whether or not the sheets had completed the formal Review and Approval (R and A) process. Once the factsheets had gone through the formal review and approval process, they could then be published both internally and externally based on their individual publication status. An extended requirement and feature of the site would be to provide a keyword search capability to search through the factsheets. Also, since the site currently resides on both the internal and external networks, it would need to be registered with the Sandia search engines in order to allow access to the content of the site by the search engines. To date, all of the above requirements and features have been created and implemented in the Factsheet web application. These have been accomplished by the use of flat text databases, which are discussed in greater detail later in this paper.

Based on trends on HTTP Archive, deployed JavaScript code size has grown 45% over the course of the year. MVC offers architectural benefits over standard JavaScript — it helps you write better organized, and therefore more maintainable code. This pattern has been used and extensively tested over multiple languages and generations of programmers. It's no coincidence that many of the most popular web programming frameworks also encapsulate MVC principles: Django, Ruby on Rails, CakePHP, Struts, or Laravell.

  4. Applications of Groundwater Helium

    Science.gov (United States)

    Kulongoski, Justin T.; Hilton, David R.

    2011-01-01

    Helium abundance and isotope variations have widespread application in groundwater-related studies. This stems from the inert nature of this noble gas and the fact that its two isotopes ? helium-3 and helium-4 ? have distinct origins and vary widely in different terrestrial reservoirs. These attributes allow He concentrations and 3He/4He isotope ratios to be used to recognize and quantify the influence of a number of potential contributors to the total He budget of a groundwater sample. These are atmospheric components, such as air-equilibrated and air-entrained He, as well as terrigenic components, including in situ (aquifer) He, deep crustal and/or mantle He and tritiogenic 3He. Each of these components can be exploited to reveal information on a number of topics, from groundwater chronology, through degassing of the Earth?s crust to the role of faults in the transfer of mantle-derived volatiles to the surface. In this review, we present a guide to how groundwater He is collected from aquifer systems and quantitatively measured in the laboratory. We then illustrate the approach of resolving the measured He characteristics into its component structures using assumptions of endmember compositions. This is followed by a discussion of the application of groundwater He to the types of topics mentioned above using case studies from aquifers in California and Australia. Finally, we present possible future research directions involving dissolved He in groundwater.

    Scott, Benjamin B; Velho, Tarciso A; Sim, Shuyin; Lois, Carlos

    2010-01-01

    The ability to introduce foreign DNA into the genome of an organism has proven to be one of the most powerful tools in modern biology. Methods for the manipulation of the animal genome have been developed at an impressive pace for 3 decades, but only in the past 5 years have useful tools for avian transgenesis emerged. The most efficient technique involves the use of replication-deficient lentiviral vectors to deliver foreign DNA into the avian germline. Although lentiviral-mediated transgenesis presents some constraints, progress in this area has garnered interest in both industry and academia for its potential applications in biological research, biotechnology, and agriculture. In this review we evaluate methods for the production of transgenic birds, focusing on the advantages and limitations of lentiviral-mediated transgenesis. We also provide an overview of future applications of this technology. The most exciting of these include disease-resistant transgenic poultry, genetically modified hens that produce therapeutic proteins in their eggs, and transgenic songbirds that serve as a model to study communication disorders. Finally, we discuss technological advances that will be necessary to make avian transgenesis a more versatile tool. PMID:21131712

    In dental hard tissue ablation, ultra-short laser pulses have proven sufficiently their potential for material ablation with negligible collateral damage providing many advantages. The absence of micro-cracks and the possibility to avoid overheating of the pulp during dental cavity preparation may be among the most important issues, the latter opening up an avenue for potential painless treatment. Beside the evident short interaction time of laser radiation with the irradiated tissue, scanning of the ultra-short pulse trains turned out to be crucial for ablating cavities of required quality and shape. Additionally, long-pulsed laser systems have demonstrated successfully their suitability for decontamination purposes. In this paper, an overview of different indications for laser application in dental therapies in both pulse regimes is presented. A special focus is set on the decontamination of dental implants in periimplantitis therapy. Having employed commercially available long pulse systems for dental applications and ultra-short 330 fs pulses, we present first results for temperature development and corresponding ablation thresholds for dental implants, as in the future more gentle implant cleaning by ultra-short laser pulses could become of interest.

  8. Nuclear applications: Future prospects

    International Nuclear Information System (INIS)

    Full text: Nuclear physics and energy research depends on and advances science and technology outside of the nuclear field. Perhaps the most commonly perceived benefits to society from nuclear and particle physics are those derived from particle beam technology. Charged particle accelerators play an increasing role in applications in industry and medicine. Neutrons produced with a high power proton accelerator in a spallation process are used from basic research, radiography in automotive industry (example fuel cell development) to transmutation of highly radioactive fission products. Production and acceleration of ultra cold neutrons provide intense and almost mono-energetic neutrons to study soft matter. Heavier radioisotopes are used in a wide field ranging from medicine to semiconductor industry (ion implantation for doping or coating technologies). Concrete examples and future trends will be given. Detailed understanding of ion physics at low energy allows the design of compact accelerator mass spectroscopy (close to table top size). The ability to measure concentrations of specific radioactive isotopes even below the natural radioactivity widens the scope of applications from archaeology, climate research to food industry. Such a compact device is close to commercialisation. (author)

    2011-05-01

    Microneedle mediated microporation has proved its potential to enhance the delivery of therapeutic drug molecules through skin over the last one decade. Several patents have been granted and cutting edge research is going on particularly for the delivery of biopharmaceuticals (macromolecules like protein or peptides). The technology involves use of micron sized needles made of diverse materials to form microchannels into the stratum corneum (or deeper), outermost barrier layer of the skin. These microchannels are deep enough to facilitate efficient drug delivery through disrupted stratum corneum but short enough to avoid bleeding or pain. So far, the microneedle technology has been explored for drug and vaccine delivery through transcutaneous route. However, the miniaturized nature of these microneedles and anticipated minimal invasiveness has led the scientists to explore and patent its possible use for several other applications.The use of this technology in combination with other enhancement techniques has also gained recent attention. This review article focuses on the latest developments in the field of microneedles as described in patent and research literature. Comprehensive review of several topics including device design/fabrication, formulation development, safety/regulatory issues, therapeutic applications and major challenges in the commercialization of microneedles as medical devices has been presented here.

  12. Dose distributions around selectron applicators

    International Nuclear Information System (INIS)

    Measured and calculated dose distributions around selectron applicators, loaded with 60Co high dose rate pellets, are presented. The effect of the stopping screw, spacers, pellets themselves and the applicator wall on the dose distribution is discussed. The measured dose distribution is in almost perfect agreement with the calculated distribution in planes perpendicular to the applicator axis and containing a source. On the applicator axis directly below the applicator the measured dose amounts to about 75% of the calculated value, when only the stopping screw attenuates the beam from a pellet. When the beam is attenuated by spacers in addition to the stopping screw, the discrepancy between the calculated and measured dose may exceed 50%. Clinically relevant source geometries are also discussed. It is shown that for most regions around the applicator the method of a simple addition of dose contributions from individual point sources is an acceptable approximation for the calculation of dose distributions around the selectron applicators

  13. Applications of high power microwaves

    International Nuclear Information System (INIS)

    The authors address a number of applications for HPM technology. There is a strong symbiotic relationship between a developing technology and its emerging applications. New technologies can generate new applications. Conversely, applications can demand development of new technological capability. High-power microwave generating systems come with size and weight penalties and problems associated with the x-radiation and collection of the electron beam. Acceptance of these difficulties requires the identification of a set of applications for which high-power operation is either demanded or results in significant improvements in peRFormance. The authors identify the following applications, and discuss their requirements and operational issues: (1) High-energy RF acceleration; (2) Atmospheric modification (both to produce artificial ionospheric mirrors for radio waves and to save the ozone layer); (3) Radar; (4) Electronic warfare; and (5) Laser pumping. In addition, they discuss several applications requiring high average power than border on HPM, power beaming and plasma heating

  14. Dynamic Reconfiguration of Application Logic During Application Migration

    Science.gov (United States)

    Klus, Holger; Schindler, Björn; Rausch, Andreas

    During migration of an application from a source to a target device, its application logic often has to be adapted to the new situation. The new situation can for instance be characterized by different hardware resources or a different usage context . Therefore, the application logic has to be adapted automatically to the new context in order to provide the most suitable behaviour before and after migration. We consider application logic that consists of components which interact with each other through well-defined interfaces. In order to adapt the behaviour of the application logic, components can be added, removed or replaced. In this chapter we introduce a concept which enables the dynamic reconfiguration of component-based applications based on context information during the migration process. Our concept enables a technology independent specification of adaptation behaviour. Furthermore, we support the specification of an application without referencing application components directly. In that way it is possible to integrate new components into applications that were not known during application development time.

    An electrode device for high pressure applications. These electrodes, designed to withstand pressure of greater than 10,000 psi, are adapted for use in microfluidic devices that employ electrokinetic or electrophoretic flow. The electrode is composed, generally, of an outer electrically insulating tubular body having a porous ceramic frit material disposed in one end of the outer body. The pores of the porous ceramic material are filled with an ion conductive polymer resin. A conductive material situated on the upper surface of the porous ceramic frit material and, thus isolated from direct contact with the electrolyte, forms a gas diffusion electrode. A metal current collector, in contact with the gas diffusion electrode, provides connection to a voltage source.

    2010-12-01

    The role of secondary refrigerants is expected to grow as the focus on the reduction of greenhouse gas emissions increases. The effectiveness of secondary refrigerants can be improved when phase changing media are introduced in place of single phase media. Operating at temperatures below the freezing point of water, ice slurry facilitates several efficiency improvements such as reductions in pumping energy consumption as well as lowering the required temperature difference in heat exchangers due to the beneficial thermo-physical properties of ice slurry. Research has shown that ice slurry can be engineered to have ideal ice particle characteristics so that it can be easily stored in tanks without agglomeration and then be extractable for pumping at very high ice fraction without plugging. In addition ice slurry can be used in many direct contact food and medical protective cooling applications. This paper provides an overview of the latest developments in ice slurry technology.

    2016-01-01

    Glaucoma is the second leading cause of blindness worldwide, and the antiglaucoma treatments currently available suffer from various complications. Nanotechnology-based treatments show a great deal of promise in overcoming these complications and form the basis for next-generation glaucoma treatment strategies, with the help of applications such as controlled release, targeted delivery, increased bioavailability, diffusion limitations, and biocompatibility. Significant progress has been made in nanomedicine in the efficiency of antiglaucoma medications, nanofabrication systems such as microelectromechanical systems that remove the limitations of nanodevices, and tissue regeneration vesicles for developing glaucoma treatments not based on intraocular pressure. With the use of these advanced technologies, the prevention of glaucoma-induced blindness will be possible in the near future. Herein, we reviewed the recent advances in nanotechnology-based treatment strategies for glaucoma. PMID:26693592

  11. Applications of Metric Coinduction

    CERN Document Server

    Kozen, Dexter

    2009-01-01

    Metric coinduction is a form of coinduction that can be used to establish properties of objects constructed as a limit of finite approximations. One can prove a coinduction step showing that some property is preserved by one step of the approximation process, then automatically infer by the coinduction principle that the property holds of the limit object. This can often be used to avoid complicated analytic arguments involving limits and convergence, replacing them with simpler algebraic arguments. This paper examines the application of this principle in a variety of areas, including infinite streams, Markov chains, Markov decision processes, and non-well-founded sets. These results point to the usefulness of coinduction as a general proof technique.

  12. Laser applications in neurosurgery

    Cerullo, Leonard J.

    1985-09-01

    The "false start" of the laser in neurosurgery should not be misconstrued as a denial of the inherent advantages of precision and gentleness in dealing with neural tissue. Rather, early investigators were frustrated by unrealistic expectations, cumbersome equipment, and a general ignorance of microtechnique. By the early 70s, microneurosurgery was well established, surgical laser equipment for free hand and microlinked application had been developed, and a more realistic view of the limitations of the laser had been established. Consequently, the late 70s really heralded the renaissance of the laser in neurosurgery. Since then, there has been an overwhelming acceptance of the tool in a variety of clinical situations, broadly categorized in five groups. 1)|Perhaps the most generally accepted area is in the removal of extra-axial tumors of the brain and spinal cord. These tumors, benign by histology but treacherous by location, do not present until a significant amount of neurological compensation has already occurred. The application of additional trauma to the neural tissue, whether by further tumor growth or surgical manipulation, frequently results in irreversible damage. Here, the ability of the laser to vaporize tissue, in a fairly hemostatic fashion, without mechanical or thermal damage to sensitive surrounding tissues, is essential. 2)|The ability to incise delicate neural tissue with minimal spread of thermal destruction to adjacent functioning tissue makes the laser the ideal instrument when tumors deep under the surface are encountered in the brain or spinal cord. Thus, the second group of applications is in the transgression of normal neural structures to arrive at deeper pathological tissue. 3)|The third area of benefit for the laser in neurosurgery has been in the performance of neuroablative procedures, calling for deliberate destruction of functioning neural tissue in a controlled fashion. Again, the precision and shape confinement of the destructive

  18. Applications of ion beams

    International Nuclear Information System (INIS)

    Charged particle accelerator was invented almost seven decades ago with the primary purpose to break the atomic nucleus. The broader inspiration, however, was to understand the structure of matter and the nature around us. Since then the accelerators have evolved enormously in terms of types, intricacies and sizes. They continue to play, primarily, the same role now also but have necessitated, over the years, invention and development of a large number of technologies that are being driven to cutting edge to meet the demands of scientists to carry their researches to unprecedented frontiers in various branches of science. While the first ever accelerator was built to break a 'simple' nucleus of lithium atom, the accelerators of today are trying to recreate the 'big bang' in the laboratory. They have been serving the scientists over the decades to discover new particles and fields. Charged particle accelerators are very commonly used to generate secondary beams for basic research and applications. The secondary beams include neutrons, antiprotons, mesons, neutrinos etc. In view of the experimentalists needs, accelerators have been developed both for electrons as well as ions. While the basic technologies do not differ much, the two varieties offer their own challenges. For each variety, the accelerator can be of linear type or circular type. Generally, a given accelerator accelerates either electrons or ions. In this report we shall be concerned only with the ion accelerators - more specifically about their applications. The accelerators most commonly used to accelerate ions are Cockroft Walton accelerator, Radio Frequency Quadrupole (RFQ) accelerator, Van-de- Graaff accelerator, linear accelerator (linac), cyclotron and synchrotron. In many situations they may operate in combination and, rarely, there exists hybrid variety also. (author)

  19. Nuclear applications for development

    International Nuclear Information System (INIS)

    Building capacity for the safe application of nuclear technologies produces tangible socioeconomic benefits to developing countries. Identifying killer infections such as extrapulmonary tuberculosis and drug resistant strains of HIV/AIDS in sub-Saharan Africa; Monitoring malaria drug resistance in Myanmar; - Teaching Jordanian farmers how to produce viable crops on salty soils; - Investigating water resources deep beneath the Nubian Desert; - Fighting acid rain in Poland; - Creating an energy strategy for Latin America; - Strengthening the security of nuclear sources in Kazakhstan. These are just some of examples of the practical ways in which the International Atomic Energy Agency (IAEA) fulfils its mandate to 'accelerate and enlarge the contribution of atomic energy to peace, health, and prosperity throughout the world'. And some of the reasons the IAEA's long history of global action was recognized through the Nobel Peace Prize in 2005. This list of activities reflects the diverse needs of Member States. It also demonstrates the enormous potential of nuclear technology and the breadth of expertise that lie within three IAEA technical programmes: Nuclear Sciences and Applications, Nuclear Energy, and Nuclear Safety and Security. More importantly, it speaks to the success of a determined effort to facilitate knowledge sharing and technology transfer through a cross-cutting mechanism known as the technical cooperation programme. Each year, the technical cooperation programme disburses approximately US $90 million, all of which is acquired through voluntary contributions from Member States. The programme concentrates on building capacity through training and education, expert advice, and equipment delivery. It is currently active in more than 110 countries across four geographic regions: Africa, Asia and the Pacific, Europe and Latin America

  20. Insulators for fusion applications

    International Nuclear Information System (INIS)

    Design studies for fusion devices and reactors have become more detailed in recent years and with this has come a better understanding of requirements and operating conditions for insulators in these machines. Ceramic and organic insulators are widely used for many components of fusion devices and reactors namely: radio frequency (RF) energy injection systems (BeO, Al2O3, Mg Al2O4, Si3N4); electrical insulation for the torus structure (SiC, Al2O3, MgO, Mg Al2O4, Si4Al2O2N6, Si3N4, Y2O3); lightly-shielded magnetic coils (MgO, MgAl2O4); the toroidal field coil (epoxies, polyimides), neutron shield (B4C, TiH2); high efficiency electrical generation; as well as the generation of very high temperatures for high efficiency hydrogen production processes (ZrO2 and Al2O3 - mat, graphite and carbon - felt). Timely development of insulators for fusion applications is clearly necessary. Those materials to be used in fusion machines should show high resistance to radiation damage and maintain their structural integrity. Now the need is urgent for a variety of radiation resistant materials, but much effort in these areas is required for insulators to be considered seriously by the design community. This document contains 14 papers from an IAEA meeting. It was the objective of this meeting to identify existing problems in analysing various situations of applications and requirements of electrical insulators and ceramics in fusion and to recommend strategies and different stages of implementation. This meeting was endorsed by the International Fusion Research Council

  1. Hydrogen energy applications

    International Nuclear Information System (INIS)

    For the Energy and Material consumption Scenarios (EMS), by which emission reduction of CO2 and other greenhouse gases can be calculated, calculations are executed by means of the MARKAL model (MARket ALlocation, a process-oriented dynamic linear programming model to minimize the costs of the energy system) for the Netherlands energy economy in the period 2000-2040, using a variable CO2 emission limit. The results of these calculations are published in a separate report (ECN-C--92-066). The use of hydrogen can play an important part in the above-mentioned period. An overview of several options to produce or use hydrogen is given and added to the MARKAL model. In this report techno-economical data and estimates were compiled for several H2-application options, which subsequently also are added to the MARKAL model. After a brief chapter on hydrogen and the impact on the reduction of CO2 emission attention is paid to stationary and mobile applications. The stationary options concern the mixing of natural gas with 10% hydrogen, a 100% substitution of natural gas by hydrogen, the use of a direct steam generator (combustion of hydrogen by means of pure oxygen, followed by steam injection to produce steam), and the use of fuel cells. The mobile options concern the use of hydrogen in the transportation sector. In brief, attention is paid to a hydrogen passenger car with an Otto engine, and a hydrogen passenger car with a fuel cell, a hybrid (metal)-hydride car, a hydrogen truck, a truck with a methanol fuel cell, a hydrogen bus, an inland canal boat with a hydrogen fuel cell, and finally a hydrogen airplane. 2 figs., 15 tabs., 1 app., 26 refs

    CERN Document Server

    Kania, Don R

    1995-01-01

    The use of diamond in electronic applications is not a new idea, but limitations in size and control of properties restricted the use of diamond to a few specialised applications. The vapour-phase synthesis of diamond, however, has facilitated serious interest in the development of diamond-based electronic devices. The process allows diamond films to be laid down over large areas. Both intrinsic and doped diamond films have a unique combination of extreme properties for high speed, high power and high temperature applications. The eleven chapters in Diamond: Electronic Properties and Applications, written by the world's foremost experts on the subject, give a complete characterisation of the material, in both intrinsic and doped forms, explain how to grow it for electronic applications, how to use the grown material, and a description of both passive and active devices in which it has been used with success. Diamond: Electronic Properties and Applications is a compendium of the available literature on the sub...

    2016-08-01

    Requirement for deaf mobile applications need to be analysed to ensure the disabilities need are instilled into the mobile applications developed for them. Universal design is understandable to comply every user needs, however specific disability is argued by the authors to have different need and requirements. These differences are among the reasons for these applications being developed to target for a specific group of people, however they are less usable and later abandoned. This study focuses on deriving requirements that are needed by the deaf in their mobile applications that are meant specifically for them. Studies on previous literature was conducted it can be concluded that graphic, text, multimedia and sign language interpreter are among mostly required features to be included in their mobile application to ensure the applications are usable for this community.

  12. Microcomputer applications, (4)

    International Nuclear Information System (INIS)

    The high performance video image processing system with a microcomputer has been applied to various fields during recent years. In this paper, a video image processing system with a Z-80 (4MHz clock, 48KB DRAM) microcomputer and its application to neutron radiography are presented. The system has the following peripheral I/O devices; a TTY to control the system, a digital cassette tape recorder and two floppy disk drives to store the programs and the image data, a dot image printer to make a copy of an image on a CRT and a RS-232C interface to communicate with a host computer. The monitor and preliminary image processing softwares were developed with the machine language and stored in EPROMs (2708). The video image signals from the TV camera are digitized with about 33msec conversion-time/frame through a video A/D converter (ADC). The digitized image data can be stored in the image buffer (32KB DRAM) linked through the window address of the microcomputer system. The digitized pictures are taken with 16 levels of gray scale and resolved to 240 x 256 picture elements (pixels) on a monochrome CRT and displayed with 16 distinct colors on a RGB video display. The neutron radiography system installed at the E-2 experimental hole of the KUR(Kyoto University Reactor) has been available for some applications in non-destructive testing. To obtain real time radiographic images a video image processing system has been introduced in this facility. The resolution of image was obtained as about 0.5mm by a super highquality X-ray camera using a NE-426 neutron scintillator. The images of a NE-426 on CRT monitors can be observed directly and visually, and so many test samples can be continuously checked for industrial purpose. The direct image of this system could be satisfactory for penetrating the side plates to test MTR type reactor fuels and for the investigation of moving objects. (J.P.N.)

  15. Radiopharmaceuticals: therapeutic applications

    International Nuclear Information System (INIS)

    Radiopharmaceuticals are chemical compounds incorporating appropriate radionuclides, which are rendered suitable for human administration. It is the artificial production of radionuclide that laid the foundation of nuclear medicine. The basic principle in designing radiolabeled compounds for therapy is to achieve a high concentration of radioactivity in the target tissue which would be capable of delivering a desirable radiation dose with minimal exposure to the critical organ (usually bone marrow). With the availability of artificially produced radionuclides, therapeutic applications were initiated. Iodine-131 for the treatment of thyroid disorders has remained the most important one. Recent advances over the past 10 years are quite dramatic. There are three important areas where considerable research work is in progress. Intraarticular administration radiocolloids appear to be valuable for the management of synovitis in patients with rheumatoid arthritis. Palliative treatment of bone metastases and total-body bone marrow irradiation seem to be feasible with bone-seeking radiopharmaceuticals. Design and development of radiolabeled compounds for targeted delivery is important, such as (a) monoclonal antibodies for specific antigens, (b) peptides for specific receptors and (c) conjugated drugs for specific tumours. Radionuclide therapy is still in its infancy and present research activities reflect future potentials. (author). 76 refs., 4 figs., 2 tabs

  16. Application of nuclear models

    International Nuclear Information System (INIS)

    The development of extensive experimental nuclear data base over the past three decades has been accompanied by parallel advancement of nuclear theory and models used to describe and interpret the measurements. This theoretical capability is important because of many nuclear data requirements that are still difficult, impractical, or even impossible to meet with present experimental techniques. Examples of such data needs are neutron cross sections for unstable fission products, which are required for neutron absorption corrections in reactor calculations; cross sections for transactinide nuclei that control production of long-lived nuclear wastes; and the extensive dosimetry, activation, and neutronic data requirements to 40 MeV that must accompany development of the Fusion Materials Irradation Test (FMIT) facility. In recent years systematic improvements have been made in the nuclear models and codes used in data evaluation and, most importantly, in the methods used to derive physically based parameters for model calculations. The newly issued ENDF/B-V evaluated data library relies in many cases on nuclear reaction theory based on compound-nucleus Hauser-Feshbach, preequilibrium and direct reaction mechanisms as well as spherical and deformed optical-model theories. The development and applications of nuclear models for data evaluation are discussed with emphasis on the 1 to 40 MeV neutron energy range

  19. Phytosanitary applications of irradiation

    International Nuclear Information System (INIS)

    Phytosanitary treatments are used to disinfest agricultural commodities of quarantine pests so that the commodities can be shipped out of quarantined areas. Ionizing irradiation is a promising phytosanitary treatment that is in- creasing in use worldwide. Almost 19000 metric tons of sweet potatoes and several fruits plus a small amount of curry leaf are irradiated each year in 6 countries, including the United States, to control a number of plant quarantine pests. Advantages over other treatments include tolerance by most fresh commodities, ability to treat in the final packaging and in pallet loads, and absence of pesticide residues. A regulatory disadvantage is lack of an independent verification of treatment efficacy because pests may be found alive during commodity inspection, although they will not complete development or reproduce. High-energy X-rays generated by electron beam are ideal for sterilizing large packages and pallet loads of food. The directional concentration and high penetration capability as well as excellent dose uniformity of X-rays allows disinfest efficiently. Application of irradiation phytosanitary in China still in its infancy. (authors)

  20. Applications of chiral symmetry

    International Nuclear Information System (INIS)

    The author discusses several topics in the applications of chiral symmetry at nonzero temperature. First, where does the rho go? The answer: up. The restoration of chiral symmetry at a temperature Tχ implies that the ρ and a1 vector mesons are degenerate in mass. In a gauged linear sigma model the ρ mass increases with temperature, mρ(Tχ) > mρ(0). The author conjectures that at Tχ the thermal ρ - a1, peak is relatively high, at about ∼1 GeV, with a width approximately that at zero temperature (up to standard kinematic factors). The ω meson also increases in mass, nearly degenerate with the ρ, but its width grows dramatically with temperature, increasing to at least ∼100 MeV by Tχ. The author also stresses how utterly remarkable the principle of vector meson dominance is, when viewed from the modern perspective of the renormalization group. Secondly, he discusses the possible appearance of disoriented chiral condensates from open-quotes quenchedclose quotes heavy ion collisions. It appears difficult to obtain large domains of disoriented chiral condensates in the standard two flavor model. This leads to the last topic, which is the phase diagram for QCD with three flavors, and its proximity to the chiral critical point. QCD may be very near this chiral critical point, and one might thereby generated large domains of disoriented chiral condensates

  1. Energy applications of superconductivity

    International Nuclear Information System (INIS)

    The excitement over the new superconductors repeats the enthusiasm following the initial discovery in 1911 as well as that following the discovery of more practical metallic materials in the early 1960s. Higher temperature and the rapid progression from 35 K to 95 K and then to 125 K in a period of less than two years increased the normal enthusiasm to what could be described whimsically as hyperbole. Such excessive optimism led to some backlash and various expressions of pessimism in the media as the difficulty of the technical challenge of development was recognized. Now nearly five years after the initial discoveries and with fairly steady progress in both the science and the technology, the hype has been reduced and a more rational atmosphere prevails. This paper reports that high-temperature superconductivity generally promises an evolutionary rather than a revolutionary impact on energy applications. In other words, it could improve efficiency and reliability, but not make large power plants or petroleum obsolete

  3. High energy applications

    International Nuclear Information System (INIS)

    Full text: From the point of view of high energy applications I would like to make the following recommendations: Neutron cross sections from the keV range up to 50 MeV are measured by dedicated mono- energetic fast neutron sources. For the design optimization of fast neutron sources, data files and models of proton and deuteron cross sections and their DDXs on Li and Be isotopes need to be improved utilizing recent experiments and new physics models for Ep dn,p < 2 GeV based on up-to-date physics models and available evaluated files, - identify target accuracies through sensitivity and uncertainty analyses using the recommended library; Inaccurate nuclear data can give rise to engineering margins of a factor 2 to 3 in high energy accelerator shielding design. Improving nuclear data of neutron inelastic scattering as well as activation cross sections for component, structural and shielding materials, such as Na, Al, Mn, Fe, Co, Ni, Cu, Zn for energies up to a few hundreds of MeV, is essential for the reduction of too conservative design margins, which in return would give a huge cost benefit; Radiation effects on micro-electronics (soft errors, damage) by cosmic-ray neutrons need to be predicted in a reliable way. Therefore, more reliable nuclear reaction models which can predict neutron-induced light-ion production from silicon in the incident energy range from MeV to GeV are strongly required. (author)

    In this invited lecture we give an overview of our 15 years of experience on streamer plasma research. Efforts are directed to integrating the competence areas of plasma physics, pulsed power technology and chemical processing. The current status is the development of a large scale pulsed corona system for gas treatment. Applications on biogas conditioning, VOC removal, odor abatement and control of traffic emissions have been demonstrated. Detailed research on electrical and chemical processes resulted in a boost of efficiencies. Energy transfer efficiency to the plasma was raised to above 90%. Simultaneous improvement of the plasma chemistry resulted in a highly efficient radical generation: O-radical production up to 50% of the theoretical maximum has been achieved. A major challenge in pulsed power driven streamers is to unravel, understand and ultimately control the complex interactions between the transient plasma, electrical circuits, and process. Even more a challenge is to yield electron energies that fit activation energies of the process. We will discuss our ideas on adjusting pulsed power waveforms and plasma reactor settings to obtain more controlled catalytic processing: the ``Chemical Transistor'' concept.

  6. Microcomputer applications, (3)

    International Nuclear Information System (INIS)

    The present report describes the architecture of interface for numerical operations, peripheral input/output devices and process input/output ( P I/O) devices of microcomputer (M6800) system. As an application of such interface this paper also reports on the rod worth measurements. In the arithmetic processing system a MOS/LSI MM57109 is interfaced with a basic system of microcomputer, with common memory in such a way that decimal arithmetic operations may be performed with simple software at machine language level. This system consists of such the peripherals and P I/O devices as, Peripherals; TTY and its compatible device, Audio or Digital Cassette Recorder, CRT Character Terminal, Mini-Floppy Disk, X-Y Recorder and X-Y Plotter, P I/O; A/D Converter, Present-Timer, Pulse Counter, Digital Clock, Universal Counter, D/A Converter and the Rod Worth Interface. If each P I/O device were connected individually to I/O port, many ports and signal lines would be needed. This problem is resolved to simplify the situation by providing with control port and I/O data port, through which interface is taken for data collection and processing. Similar interface is connected to the instrumentation system of the KUR and a good result could be obtained on the rod worth measurements. (author)

  7. Thermoluminescence - physics and applications

    International Nuclear Information System (INIS)

    The interaction of ionizing radiations with matter leads to various effects, some of which leave memory in the target material. These memory effects can be seen as the after-effects of the irradiation. Thermoluminescence is one such phenomenon in the insulating solids. This paper describes the sequence of the physical events beginning with the incidence of an ionizing particle, leading to a trail of atomic and electronic displacements which stabilize in the form of so called defect centres. These defects - interstitials, colour centres, etc., store energy in their configuration. Most of the damage effects are reversible. The return of the displaced entities to their original site leads to the release of the stored energy. Thermoluminescence is the result of the re-adjustment (relaxation) of the displaced electrons. The stimulation for the relaxation process is provided by heating of the irradiated sample. The kinetics of the thermoluminescence process has been explained phenomenologically. The correspondence between the defect centres and the TL glow peaks has remained vague or ambiguous even in the most widely studied TL materials. Notwithstanding this deficiency, the phenomenon has found many practical applications.

    Full Text Available Microencapsulation technology allows a compound to be encapsulated inside a tiny sphere known as microsphere/microcapsule, having an average diameter as small as 1 mm to several hundred micro meters. Many different active materials like drugs, enzymes, vitamins, pesticides, flavours and catalysts have been successfully encapsulated inside microballoons or microcapsules made from a variety of polymeric and non polymeric materials including poly(ethylene glycols, poly(methacrylates, poly(styrenes, cellulose, poly(lactides, poly(lactide-co-glycolides, gelatin and acacia, etc. These microcapsules release their contents at appropriate time by using different release mechanisms, depending on the end use of encapsulated products. This technology has been used in several fields including pharmaceutical, agriculture, food, printing, cosmetic, textile and defence. In defence sector this technology has introduced the concept of self-healing composites as well as chemical decontaminating fabrics. This review paper highlights the major reasons behind microencapsulation, important techniques of microencapsulation and application of microencapsulated products in different areas of science and technology.Defence Science Journal, 2009, 59(1, pp.82-95, DOI:http://dx.doi.org/10.14429/dsj.59.1489

    Switching techniques have been first proposed as a spacial diversity techniques. These techniques have been shown to reduce considerably the processing load while letting multi-antenna systems achieve a specific target performance. In this thesis, we take a different look at the switching schemes by implementing them for different other wireless applications. More specifically, this thesis consists of three main parts, where the first part considers a multiuser environment and an adaptive scheduling algorithm based on the switching with post-selection scheme for statistically independent but non-identically distributed channel conditions. The performance of this switched based scheduler is investigated and a multitude of performance metrics are presented. In a second part, we propose and analyze the performance of three switched-based algorithms for interference reduction in the downlink of over-loaded femtocells. For instance, performance metrics are derived in closed-form and these metrics are used to compare these three proposed schemes. Finally in a third part, a switch based opportunistic channel access scheme is proposed for a cognitive radio system and its performance is analyzed in terms of two new proposed metrics namely the average cognitive radio access and the waiting time duration.

    Full Text Available Microcapsule is a tiny sphere including core material/internal phase or fill, coated with/surrounded by wall know as shell, coating or membrane. The usual size range of the microcapsule lies between 1 to 1000 μm. The technique is usually applied for targeted drug delivery, protection of the molecule and stability if the core material. Microencapsulation system offers potential advantages over conventional drug delivery systems and also established as unique carrier systems for many pharmaceuticals. This article contains the traditional and the recent pharmaceutical applications of microecapsules. The microcapsules are widely applied in pharmaceutical for Novel drug Delivery System (NDDS, latest formulations, Delivery of DNA Vaccines, Pro Drug Approach, Biodegradable and biocompatible material. Other then pharmaceutical microcapsules are widely used in delivery of probiotic, pesticide industry, food technology, beverages and cell immobilization etc. Although significant advances have been made in the field of microencapsulation, still many challenges need to be rectified during the appropriate selection of core materials, coating materials and process techniques.

  12. Clinical applications of radioimmunolocalisation

    International Nuclear Information System (INIS)

    Localization of tumours by external scintigraphy after intravenous administration of radiolabeled antibody directed against a tumour-associated antigen [radioimmunolocalisation (RIL)] might be expected to solve many of the problems of conventional tumour imaging. Although no truly specific tumour antigen is known, there are many tumour-associated antigens which are present in much higher concentrations in certain tumours than in tissues which are normal or affected by other diseases. This feature has the potential to endow RIL with a degree of specificity not exhibited by imaging methods such as computerised tomography (CT), ultrasound (US) or nuclear magnetic resonance (NMR) which reflect the physical characteristics of tissues. The clinical application of new imaging methods depends partly on their comparative performance in terms of sensitivity and specificity and also on ways in which the unique features of each can be exploited to optimize the management of individual patients. There are significant deficiencies with all the existing imaging methods; this chapter discusses the extent to which RIL may fill some of the gaps. Particular attention will be paid to situations where the result has consequences for patient management. Much of the work cited was carried out in experimental systems and on more than 300 patients at Charing Cross Hospital between 1979 and 1984

    The rising count and shrinking feature size of transistors within modern computers is making them increasingly vulnerable to various types of soft faults. This problem is especially acute in high-performance computing (HPC) systems used for scientific computing, because these systems include many thousands of compute cores and nodes, all of which may be utilized in a single large-scale run. The increasing vulnerability of HPC applications to errors induced by soft faults is motivating extensive work on techniques to make these applications more resiilent to such faults, ranging from generic techniques such as replication or checkpoint/restart to algorithmspecific error detection and tolerance techniques. Effective use of such techniques requires a detailed understanding of how a given application is affected by soft faults to ensure that (i) efforts to improve application resilience are spent in the code regions most vulnerable to faults and (ii) the appropriate resilience technique is applied to each code region. This paper presents XRay, a tool to view the application vulnerability to soft errors, and illustrates how XRay can be used in the context of a representative application. In addition to providing actionable insights into application behavior XRay automatically selects the number of fault injection experiments required to provide an informative view of application behavior, ensuring that the information is statistically well-grounded without performing unnecessary experiments.
