    International Nuclear Information System (INIS)

    The possibility of applying HTGRs in Turkey are discussed from economical and power consumption and production points of view. Modular type new small plants may give a considerable opportunity to a developing country to embark in nuclear energy and to walk hand in hand with a new technology. Combined heat/power stations which can be installed near the facility or high population areas can be used as heat and power source in big accommodation centers and petrochemical complex. Smaller units are suitable in accommodation centers with lower population and in fertilizer plants and paper mills etc. HTGRs representing inherently safe design and also ensuring easy public acceptance might be used for these purposes

  8. Alanine - ESR dosimetry, feasibility and possible applications

    International Nuclear Information System (INIS)

    Alanine ESR dosimetry presents a great interest for quality controls in radiotherapy. This new developed water equivalent alanine dosimeter allows a reproducible dose measurement, by a non-destructive readout technique in a large dose range. In this paper the stability of the dosimeter response has been shown but also its independence with the energy or the dose rate of the absorbed radiation. Through this different studies, one can broaden the application field of alanine / ESR dosimetry especially for in-vivo dosimetry. The results of the experiments and the intra operative treatment, indicate that this kind of dosimetry seems to be a promising technique for in-vivo quality controls in electron beam, γ ray or X ray radiotherapy.

  9. Juridic status: canonical provisions, possible applications.

    Science.gov (United States)

    Morrisey, F G

    1986-09-01

    The 1983 Code of Canon Law presents the basic legislation regarding juridic persons, which are entities brought into existence to assist in carrying out the Church's mission. Juridic persons by nature are perpetual and are not directly identified with their members. The private juridic person, a concept introduced in the 1983 code, operates collegially on behalf of its members or noncollegially on behalf of the things that constitute it. A ministry that receives private juridic status does not share as integrally in the Church's name. The latter therefore has more duties to fulfill in regard to observance of Church law, particularly that concerning the administration of temporal goods. The goods of a private juridic person, in contrast, are not ecclesiastical and thus are not subject to canon law. Instead, the private juridic persons' statutes provide norms for their administration. Canon law in establishing juridic persons enables the ministries they represent to last beyond the lives of those who initiated the ministries. Juridic persons offer both security and possibilities for concerted apostolic activity in the Church. PMID:10277620

  10. Possibilities of special cements in ceramic applications

    International Nuclear Information System (INIS)

    About 25 years ago, the only way to have confinement material for high temperature applications was to prepare a ceramic by sintering or fusion at high temperature. A new technology came, with the production of Low Cement Castables. This new product was obtained by a careful choice of the granulometry of the aggregates, an optimization of the defloculation of fine particles, including the cement (Calcium Aluminate Cement) and the addition of silica fume. Silica fume brought two improvements: a) a fluidifying effect, due partly to the low sensitivity of viscosity to pH, and partly to the geometric effect of the nicely spherical particle, b) a chemical effect, brought by the reaction of silica and Calcium Aluminate Cement to give a coherent zeolithic structure, through which water could escape during the first firing. From a ceramist point of view, it is interesting to understand how this components, nearly colloidal system mixed in water can be heated up to ceramization without any noticeable change in mechanical characteristics and shrinkage. From a more practical point of view, it is also interesting to realize that some characteristics, usually attributed only to ceramics, also apply with low cement castables technology: high compressive strength, flexural strength, corrosion resistance, abrasion resistance, impact resistance.

  11. Graphene Casimir Interactions and Some Possible Applications

    Science.gov (United States)

    Phan, Anh D.

    Scientific development requires profound understandings of micromechanical and nanomechanical systems (MEMS/NEMS) due to their applications not only in the technological world, but also for scientific understanding. At the micro- or nano-scale, when two objects are brought close together, the existence of stiction or adhesion is inevitable and plays an important role in the behavior operation of these systems. Such effects are due to surface dispersion forces, such as the van der Waals or Casimir interactions. The scientific understanding of these forces is particularly important for low-dimensional materials. In addition, the discovery of materials, such as graphitic systems has provided opportunities for new classes of devices and challenging fundamental problems. Therefore, investigations of the van der Waals or Caismir forces in graphene-based systems, in particular, and the solution generating non-touching systems are needed. In this study, the Casimir force involving 2D graphene is investigated under various conditions. The Casimir interaction is usually studied in the framework of the Lifshitz theory. According to this theory, it is essential to know the frequency-dependent reflection coefficients of materials. Here, it is found that the graphene reflection coefficients strongly depend on the optical conductivity of graphene, which is described by the Kubo formalism. When objects are placed in vacuum, the Casimir force is attractive and leads to adhesion on the surface. We find that the Casimir repulsion can be obtained by replacing vacuum with a suitable liquid. Our studies show that bromobenzene is the liquid providing this effect. We also find that this long-range force is temperature dependent and graphene/bromobenzene/metal substrate configuration can be used to demonstrate merely thermal Casimir interaction at room temperature and micrometer distances. These findings would provide good guidance and predictions for practical studies.

  18. Expert systems - basic principles and possible applications in nuclear energy

    International Nuclear Information System (INIS)

    One of the primary goals of the application of mathematical methods and computational techniques in reactor physics is the effective and accurate solution of the neutron diffusion equation under various conditions. To reach this goal still requires much skill, experience, knowledge and imagination as can be seen from various contributions at this and other conferences. Experts are necessary. Will expert systems replace them. We shall discuss this question by describing the basic principles of problem solving by expert systems as compared to problem solving by mathematical and computational methods. From this we shall identify areas of possible applications of the new techniques in nuclear energy and develop some thoughts on present limitations. As a result we conclude that expert systems will not be able to replace experts as long as the experts use the systems to improve their own expertise

  19. Hybrid Welding Possibilities of Thick Sections for Arctic Applications

    Science.gov (United States)

    Bunaziv, Ivan; Akselsen, Odd M.; Ren, Xiaobo; Salminen, Antti

    The arctic shelf contains about 20% of all undiscovered hydrocarbons on our planet, therefore oil and gas industry requires advanced steels to be used which withstand appropriate fracture toughness up to -60 °C and suitable welding technologies. High brightness laser with combination with arc source can be appropriate joining process even for very high strength advanced steels above 700 MPa for low temperature applications. Hybrid welding has improved each year becoming more standardized and reliable welding process. However, until now, its application was limited to shipbuilding and pipeline industry. Due to many reasonable advantages, hybrid welding, especially when it is combined with MIG/MAG, can be used in every possible industry. Inherent filler wire addition from the MIG/MAG source can improve fracture toughness at lower temperatures and increase overall productivity. This paper provides information about recent breakthrough in hybrid welding of thick section high-strength steels.

  20. Understanding quantum confinement in nanowires: basics, applications and possible laws

    International Nuclear Information System (INIS)

    A comprehensive investigation of quantum confinement in nanowires has been carried out. Though applied to silicon nanowires (SiNWs), it is general and applicable to all nanowires. Fundamentals and applications of quantum confinement in nanowires and possible laws obeyed by these nanowires, have been investigated. These laws may serve as backbones of nanowire science and technology. The relationship between energy band gap and nanowire diameter has been studied. This relationship appears to be universal. A thorough review indicates that the first principles results for quantum confinement vary widely. The possible cause of this variation has been examined. Surface passivation and surface reconstruction of nanowires have been elucidated. It has been found that quantum confinement owes its origin to surface strain resulting from surface passivation and surface reconstruction and hence thin nanowires may actually be crystalline-core/amorphous-shell (c-Si/a-Si) nanowires. Experimental data available in the literature corroborate with the suggestion. The study also reveals an intrinsic relationship between quantum confinement and the surface amorphicity of nanowires. It demonstrates that surface amorphicity may be an important tool to investigate the electronic, optoelectronic and sensorial properties of quantum-confined nanowires. (topical review)

    2013-01-01

    Full Text Available Brewer’s spent grain is the major by-product in beer production. It is produced in large quantities (20 kg per 100 liters of produced beer throughout the year at a low cost or no cost, and due to its high protein and carbohydrates content it can be used as a raw material in biotechnology. Biotechnological processes based on renewable agro-industrial by-products have ecological (zero CO2 emission, eco-friendly by-products and economical (cheap raw materials and reduction of storage costs advantages. The use of brewer’s spent grain is still limited, being basically used as animal feed. Researchers are trying to improve the application of brewer’s spent grain by finding alternative uses apart from the current general use as an animal feed. Its possible applications are in human nutrition, as a raw material in biotechnology, energy production, charcoal production, paper manufacture, as a brick component, and adsorbent. In biotechnology brewer’s spent grain could be used as a substrate for cultivation of microorganisms and enzyme production, additive of yeast carrier in beer fermentation, raw material in production of lactic acid, bioethanol, biogas, phenolic acids, xylitol, and pullulan. Some possible applications for brewer’s spent grain are described in this article including pre-treatment conditions (different procedures for polysaccharides, hemicelluloses, and cellulose hydrolysis, working microorganisms, fermentation parameters and obtained yields. The chemical composition of brewer’s spent grain varies according to barley variety, harvesting time, malting and mashing conditions, and a quality and type of unmalted raw material used in beer production. Brewer’s spent grain is lignocellulosic material rich in protein and fibre, which account for approximately 20 and 70% of its composition, respectively.

  2. Possible applications of synchrotron radiation for materials science

    International Nuclear Information System (INIS)

    In the past 20 years, synchrotron radiation has become an important aid for solid-state physicists, chemists and biologists. On the other hand, the use of synchrotron radiation for experimental studies of a large series of specimens is still in the preliminary stage, however, is necessary for the analyzation of materials. In this paper, present and future possible applications of synchrotron radiation for the characterization of advanced materials are discussed. Beside the further optimization of techniques for the analysis of the atomic structure (e.g. diffraction, absorption spectroscopy), essential progress has to be expected in the field of nondestructive, threedimensional characterization of the microstructure of metallic and ceramic materials, especially during the synthesis of materials.

  3. Possible applications of synchrotron radiation to x-ray astrophysics

    International Nuclear Information System (INIS)

    As the instrumentation for observations in high energy astrophysics has grown increasingly sophisticated, so too has the need developed for improved calibration techniques and facilities. Contemporary satellite-borne observatories contain high resolution spectrometers, polarimeters and x-ray image-forming optics focussed on position sensitive detectors. The Advanced X-ray Astrophysics Facility, a planned free-flying, shuttle-launched x-ray telescope (1.2 m diameter, 10 m focal length), will provide 0.5 arcsecond imagery over a several arcminute field and spectrometry with E/ΔE > 1000 in the energy range 0.1 to 8 keV. Other telescopes in the planning stage include the possibility of approx. 0.5 arcminute imagery at energies in excess of 100 keV. A few examples from the long list of calibration needs of inidvidual detectors and subsystems are listed as applications of synchrotron radiation

    Full Text Available In this paper, the possibilities of solar energy application in the biggest Russian cities are studied and analyzed. The main research goal is to investigate the possibility of solar energy technical use in Russian regions. The research method is based on the calculation of the territory power capacity and its sufficiency for solar power engineering development. To this purpose, the authors have carried out the analysis of total solar radiation falling on the horizontal and inclined surfaces within an astronomical year. The study is carried out on the basis of the data using spatial statistics of solar radiation inflow in different seasons during the annual cycle. The assessment of solar radiation sufficiency by "technically accepted" criterion is made on the basis of B. Veynberg criteria. Finally, the authors conclude that the effectiveness of the solar energy production development is the most appropriate in the city of Vladivostok and obviously, it is not prospective in the authors’ places of residence, such as Perm and Sverdlovsk Regions.

    During recent years civil application of thermography in Germany has experienced a remarkable development in general but especially in the building trade. On the one hand there was an increase of user-oriented know-how,and on the other hand a growing public knowledge and acceptance mainly induced by a lot of governmental and commercial publications on energy conservation. From a practical viewpoint a description of interesting possibilities but also narrow limitations of four present-day application areas is given : 1. scanning of buildings from inside and outside - for fault analysis and all kinds of expertises including popular energy conservation consulting 2. mapping of plastered half-timbered houses (constructed in 13.-17. century, plastered in some parts of germany in 18. and 19. century) - for renovation and re-establishment of original historical shape 3. visualization of reinforcement in concrete for careful hole-drilling In large structures f.i. nuclear power plants according to safety regulations 4. localization of leakages in floor heating and tap water systems - for cost effective repair and status reports, mainly by order of insurance-companies.

  6. W-Cu gradient materials - processing, properties and application possibilities

    International Nuclear Information System (INIS)

    The functionally graded material (FGM) of tungsten with its high thermal and mechanical resistance and copper with its very high thermal and electrical conductivity and ductility expands the application fields of this material in the direction of extreme demands such as plasma facing components in fusion reactors. The PM-production of W-Cu-gradients recommends itself because of the possibility to form the gradient by the mixing of powder components, but is also demanding because of the differences in their sintering behavior and thermal expansions. W-Gu-gradient samples of different concentration profiles have been formed in layers by powder stacking in a die and continuously by centrifugal powder forming. The consolidation routes were determined by the concentration areas of the gradients and encompass liquid phase sintering, pressure assisted solid phase sintering and the application of coated Tungsten powder and sintering additives. The microstructure and the concentration profiles of the samples have been investigated metaliographically and by EDX. The influence of processing and the gradient profile of the properties have been characterized by TRS and the investigation of residual thermal stresses by neutron diffraction. (author)

  7. Possible applications of clinoptilolites for natural water purification

    Directory of Open Access Journals (Sweden)

    N.I. Vatin

    2013-03-01

    Full Text Available Possible applications of clinoptilolites (CP in natural water purification processes from various contaminants are evaluated. Sorption properties of CP in various deposits of Russia are studied in relation to heavy metal ions. It was found that the studied specimens have a considerable sorption exchange capacity not only for ions of toxic (Hg2+, Cd2+, Pb2', but also other heavy metals (Cu2+, Co2+, Ni2+, Zn2+, Ba2+ , Sr2+. It is shown that CP sorption capacity is more efficient when a Mn2+ ion is removed from natural water compared to synthetic ion-exchange resins and activated coals. The dynamic sorption capacities for a Mn2+ ion up to a breakthrough 0.01 mg/1 and 0.1 mg/1 is determined. The CP sorption capacity is insignificant for various halide ions except a fluoride ion the removal of which from natural underground waters is possible with the help of sorption on CP. It was proposed to use CP for removing natural radionuclides (radium 226 and potassium 40 from deep wellbore waters. The purification efficiency with the initial radium 226 concentration at the level 3,0 Bq/I (30 MPC was not below 96%. The efficiency of removing potassium 40 natural isotope depends on the CP form and is maximal for Na form. Post treatment of natural waters after their coagulation treatment with the use of CP has been studied. It is shown that sorption filters with CP allow not only post-treatment of waters from excessive aluminum and zinc, but also additional reduction of odor, color, and ammonium ion content.

  8. Photosynthetic Reaction Centres – from Basic Research to Application Possibilities

    Directory of Open Access Journals (Sweden)

    Krisztina NAGY

    2010-06-01

    Full Text Available There is no doubt that studying the photosynthetic conversion of light into chemical energy is extremely important in many points of view: 1 technical-in order to improve the utilization of the solar energy; 2 food production – to improve the photosynthetic production of plants in agriculture; 3 ecology – keeping the primer production in ecosystems in the biosphere balanced, etc. In the photosynthetic reaction centre protein, RC, light energy is converted by a quantum yield of almost unity. There is no such a system designed by human which is able to do that. The RC purified from purple bacteria provides an extremely unique system for studying the requirements for high efficiency conversion of light into electrochemical energy. Thanks to the recent structural (e.g. crystallography (Nobel prize to Michel, Deisenhofer, Huber and functional (Nobel prize to Marcus results together with the works of molecular biology, computer- and electro-techniques, a wealth of information made a relatively clear picture about the kinetics, energetics and stabilization of electron transport within this protein that opens possibilities for new generation practical applications. In this paper we provide a short summary of fields in which the reaction centre protein can be important from practical points of view.

  9. Possibility of radiation application to development of substitute energy

    International Nuclear Information System (INIS)

    Interest in the technique utilizing biomass is growing as one of the alternate energies to be developed accompanying the advance of chronic, long-lasting oil crisis, and its investigation has begun as a national project in respective government offices. Biomass is essentially equal to the amount of vegetable resources composed of the raw materials of cellulose and starch groups. The authors made some consideration on the contribution of radiation to the saccharification and fermentation of cellulose. First, the trend of the technique for utilizing cellulose resources is reported, and next, the utilization of radiation to the preliminary treatment of cellulose raw material and the technique for fixing enzymes and bacteria with radiation and its application to the development of resources are described. Finally, the saccharification of cellulose resources with fixed enzymes and bacteria is described. Although it is difficult at the present stage to make full economical comparison among various saccharification methods, according to the calculation made by the authors, in the comparison of the UC method by Wilke and others (mechanical crushing - saccharification of enzymatic aqueous solution) with the method introducing the fixation technique (preliminary irradiation - saccharification by fixed enzymes), the saccharifying cost is 6.56 cents/pound in case of the former, and 4.53 cents/pound in case of the latter. Since the technique is not established in many points, it is desired to improve efficiency by simplifying the pretreatment, saccharification and fermentation processes as far as possible.

  10. Neutron spin manipulation optics: basic principles and possible applications

    International Nuclear Information System (INIS)

    A number of basic elements for neutron spin manipulation optics (NSMO) based on Larmor and non-Larmor (quantum) precessions under reflection are considered. It is concluded that transition to 3D in neutron polarization optics may bring additional instrumental possibilities. New neutron optical devices will include spin turners (particularly, π/2-turners and π- turners, or flippers), spin precessors and antiprecessors, 3D-polarizers, 3D-analyzers, 3D- rotators, spin manipulators, hyper-polarizers. The innovative neutron optics is directly applicable to developing 3D polarization and polarimetry techniques, such as reflectometry with 3D- polarimetry, Neutron optical Spin Echo (NoSE), including compact NoSE and TOF NoSE schemes. A hyper-polarizer is a device which not only separates neutrons with the opposite spins, but also flips the 'wrong' spins. Thus, hyper-polarizers can double the intensity of polarized neutron beams, although a gain in the intensity can be achieved only with the increase either in the angular divergence or in the width of the beam, in full accordance with the Liouville theorem. The tasks to be solved for implementation of the NSMO concepts are discussed.

    This paper presents a review on state-of-the-art of thin-film transistor (TFT) technology and its wide range of applications, not only in liquid crystal displays (TFT-LCDs), but also in sensing devices. The history of the evolution of the technology is first given. Then the standard applications of TFT-LCDs, and X-ray detectors, followed by state-of-the-art applications in the field of chemical and biochemical sensing are presented. TFT technology allows the fabrication of dense arrays of independent and transparent microelectrodes on large glass substrates. The potential of these devices as electrical substrates for biological cell applications is then described. The possibility of using TFT array substrates as new tools for electrical experiments on biological cells has been investigated for the first time by our group. Dielectrophoresis experiments and impedance measurements on yeast cells are presented here. Their promising results open the door towards new applications of TFT technology.

    Abstract Background: Traditional Chinese acupuncture has a history of more than 2500 years and is one of the best-known complementary and alternative therapies. Acupuncture stimulates the nervous system and alters the processing and perception of pain signals and also releases natural painkillers, such as endorphins and serotonin in the nervous system. Acupuncture's successful use for various dental conditions has been proven. Thus, it is important for the dental clinicians to be familiar with the applications of acupuncture for dental disorders. Objective: One aim of this article is to review related articles in the literature that have focused on acupuncture and its applications in dentistry. Another aim is to provide a quick sketch of acupuncture use in dentistry for dental clinicians. Materials and Methods: A detailed search was performed to identify systematic reviews and research articles, using PUBMED and the Cochrane Database of Systematic Reviews. Language was restricted to English. Key search terms were acupuncture in dentistry, myofacial pain, temporomandibular disorders, xerostomia, dental pain and gag reflex. Results: All of the current the authors independently extracted data for analysis and review. Two independent reviewers screened the titles and abstracts of all the articles for eligibility. When the reviewers noted that an abstract or title of an article indicated that the article was potentially useful, full copies were retrieved. Ultimately, 40 articles underwent full-text review. Conclusions: The research to date certainly offers valid applications of acupuncture in dentistry. Meanwhile, practical strategies with the highest success rates are needed to use in further interventions. PMID:25538815

    Full Text Available Introduction. Infrared thermography or thermovision is increasingly applicable in sport and sport rehabilitation. Thermic forms, thermic imprints, temperature and isotherm distribution, temperature gradient change are the terms that are more and more often met in sport medicine and medicine, in general. Case report. We presented two examples of thermovision application: in detection of muscle injury and changes of the feet exposed to low temperature. In the first example the thermovision method was used for analyzing heat distribution in an athlete with back muscles injury. With a special original method of local cooling the place and degree of injury was precisely localized and determined, respectively, regardless high environmental temperature. In the second case the thermovision method was for the first time applied in a runner whose feet was exposed to low temperature. Significant hypothermia of the feet was detected by the method and appropriate treatment was performed. Thanks to this the athlete had no harmful consequences. Conclusion. Thermovision is fast and efficient in detecting different kind of injuries, so its increased use in the future can be expected.

    Full Text Available Geography is a science that follows modern trends in the development of contemporary science. One of the crucial things that gives teaching process a high quality in the application of modern techniques and methods. Modern organization of the teaching process in primary and secondary schools is unimaginable without innovations. This would mean changes and new elements in all segments of the teaching process. Good organization, innovation and new tendencies in the development of the science can raise the quality of the teaching process, thus enabling the student to study fully and rationally. Innovations should help students develop a dialectic way of thinking when explaining objects, phenomena and processes in nature and society, as well as enable them to notice cause and effect relationships. The application of new methods should provide maximum activity of the students in terms of their research and independent work. Computers are used in many different ways therefore they can be used very rationally in different segments of the teaching process.

  1. Potentialities and possible applications of a new analytical method (PIXE)

    International Nuclear Information System (INIS)

    In 1970, a new method was introduced for trace analysis, namely, the X-ray emission induced by charged particles (PIXE). It has been shown that when protons in the few MeV range are used for the excitation of inner shell electrons and solid state detectors for the detection of the characteristic X-rays, we dispose of a powerful multi-elemental analytical tool of high sensitivity. In contrast to activation spectrometry, this is an in beam technique, irradiation and measuring being performed at the same time. The foundations of the method are described experimental arrangements and problems related to beam transport, target preparation an spectrum analysis. A detailed discussion on precision, accuracy and sensitivity is presented. Applications in biology, medicine, environmental and materials sciences are discussed. (Author)

    The rapid single-flux quantum electronics (RSFQ) is a superconducting, naturally digital circuit family which is currently close to being commercially applied. RSFQ is outstanding because of its very low switching energy resulting in very low power consumption. This advantage causes, however, a significant influence of thermal noise. For industrial applications, a certain noise immunity is required which is still a challenge, especially for circuits of higher complexity. Integrating phase-shifting elements is a new concept for further improvements concerning stability against the influence of thermal noise. We have already shown that the implementation of phase-shifting elements significantly reduces the influence of thermal noise on circuit behavior by experimentally analyzing the bit-error rate (Mielke et al 2009 IEEE Trans. Appl. Supercond. 19 621-5). Concepts which are easily implementable in standard niobium technology are especially promising. The {pi}-phaseshifter consists of a superconducting loop which is able to store a single flux quantum. The loop current related to the stored flux creates a well-defined phase shift. To achieve the correct functionality of complex circuits it is essential to store exactly one flux quantum in each {pi}-phaseshifter during the cooling down of the chip. Thus, for studying the feasibility of this new approach, the initialization reliability of the {pi}-phaseshifter needs to be verified. We present an experimental investigation of this reliability to obtain a general assessment for the application of the {pi}-phaseshifter in niobium technology. Furthermore, we compare the configuration shielded by a solid ground plane with a configuration with a ground-plane hole below the {pi}-phaseshifter. Justified by the experimental results we suggest programmable RSFQ circuits based on {pi}-phaseshifters. The characteristics of these devices can be influenced by a controlled initialization of the {pi}-phaseshifter. The fabrication was

  5. Possible Laminographic and Tomosynthesis Applications for Wolter Microscope Scan Geometries

    International Nuclear Information System (INIS)

    The Wolter microscope includes a number of attractive features for x-ray imaging, and possible connections to laminographic and tomosynthesis 3D object recovery algorithms. This type of instrument employs x-ray optics to sift out single energy x-rays from a broader spectral energy source, and direct those x-rays to a ''focus plane'' similar to the operation of a optical microscope (see Figure 1 for schematic of a Wolter instrument). Unlike optical microscopes the 3D object can be thick in the direction of the x-rays and in this case more of the intensity of the image is affected by the out-of-focus planes, since the ray-paths span the entire depth of the object. It is clear that the ''in-focus'' plane of a Wolter contain more 3D information than a simple ''point-projection'' radiograph. However, it is not clear just how the impact of the out-of-focus planes obscures or distorts features of interest for the in-focus planes. Further, it is not clear just how object positioning can be combined with multiple acquisitions to enable recovery of other planes within the object function or the entire object function. Of particular interest here are Wolter microscopes configured for mesoscale objects (mm extent with um features). Laminographic and tomosynthesis scanning methods can be strategic for this type of inspection instrument. First, photon output for inspection purposes can be meager in this type of ''small field of view'' system. With laboratory x-ray sources a single image can require up to 10 minutes to accumulate adequate signal. Techniques that can obtain 3D object information from small numbers of views, rotational or translational, are consequently at a premium. Laminographic and tomosynthesis scanning methods require relatively small numbers of views (2-30). Secondly, the Wolter microscope scan geometry in a single view is a fit with the type of source-detector geometry achieved through source-object-detector re-positioning in laminographic and tomosynthesis

  7. Novel bispidine ligands with a possible application in nuclear medicine

    International Nuclear Information System (INIS)

    Due to our current way of life and the environmental influences we are exposed in the industrial nations, cancer diseases turn out to be a more and more serious threat to our civilization. The ongoing research during the last decades leads to a better insight in cancer diseases and enables an earlier recognition of developing carcinoma. The detection of pathological tissue changes at an early stage increases the patients' chances of cure. Magnetic resonance tomography (MRT) and computed tomography (CT) as well as radiopharmaceutically assisted imaging techniques, like positron emission tomography (PET) and scintigraphy are an indispensable clinical tool in the oncological early diagnosis. By the development of multimodality imaging agents that combine the benefits of several imaging techniques, the early recognition of tumors can be more efficient and in consequence a matching therapy can be applied. This thesis deals with the synthesis of novel bispidine based ligands and their transition metal complexes as potential mono- and bimodal imaging agents for a 64Cu-assisted radiopharmaceutical application in positron emission tomography (PET) and optical imaging (OI). The synthesized ligands L and LOH are offering the opportunity to build up a ruthenium(II) polypyridine complex by one of the ligand's donor sets, to act as a fluorescence dye for optical imaging (OI), and to coordinate 64CuII by the ligand's vacant cavity for positron emission tomography (PET). The RuII complex exhibits two different fluorescence activities with two different lifetimes and only one of the two fluorescences is quenched by subsequent complexation of CuII. The calculated CuII stability constant of L and LOH is similar to that of the isomeric ligand N2py2 which has been already evaluated as a 64Cu-radiotracer. Further transition metal complexes of FeII, FeIII and MnII are dealing with interesting structural properties like pentagonal bipyramidal geometries. For the development of stable and

  8. ULF wave index and its possible applications in space physics

    International Nuclear Information System (INIS)

    The solar wind-magnetosphere interaction has a turbulent character, which is not accounted for by commonly used geomagnetic indices and OMNI parameters. To quantify the level of low-frequency turbulence/variability of the geomagnetic field, IMP, and solar wind plasma, we have introduced ULP wave power indices. These simple hourly indices are based on the integrated spectral power in the band 2-7 mHz or wavelet power with time scales∼10-100 min. The ground wave index has been produced from the data of global magnetometer arrays in the Northern Hemisphere. The interplanetary and geostationary wave indices have been calculated using magnetometer and plasma data from interplanetary and geosynchronous satellites. These indices have turned out to be useful for statistical analysis of various space weather problems. These indices enable one to examine easily the statistical correspondence between the ULP activity and interplanetary conditions. For example, the enhancements of relativistic electrons at the geosynchronous orbit were not directly related to the intensity of magnetic storms, but they correlated well with intervals of elevated ground ULP wave index. This fact confirmed the importance of magnetospheric ULP turbulence in energising electrons up to relativistic energies. The interplanetary index has revealed statistically the role of the interplanetary turbulence in driving the magnetosphere by the IMP/solar wind. The application of this index to the analysis of conditions in the solar wind before magnetic storm onsets has shown that a weak irregular increase of the solar wind density is observed on average 2 days prior to storm commencement. The ULP index database for the period since 1991 is freely available via anonymous FTP for all interested researchers for further validation and statistical studies. (authors)

    Speckle patterns to be observed in an output light spot from an optical fiber are known to be changed due to external disturbances applied onto the optical fiber. In order to investigate possibilities of utilizing such changes in speckle patterns for sensing application, a certain load was applied onto a jacket-covered communication-grade multi-mode glass optical fiber through which laser beams emitted from a laser diode were propagating, and observed changes in speckle patterns in the output light spot from the optical fiber were investigated both as image data via a CCD camera and as an output voltage from a photovoltaic panel irradiated with the output light spot. The load was applied via a load application mechanism in which several ridges were provided onto opposite flat plates and a certain number of weights were placed there so that corrugated bending of the optical fiber was intentionally induced via load application due to the ridges. The obtained results showed that the number of speckles in the observed pattern in the output light spot as well as the output voltage from the photovoltaic panel irradiated with the output light spot showed decreases upon load application with relatively satisfactory repeatability. When the load was reduced, i.e., the weights were removed, the number of speckles then showed recovery. These results indicate there is a certain possibility of utilizing changes in speckle patterns for sensing of load application onto the optical fiber.

    Recent development trends largely look for possibilities of a wider use of natural materials and local resources. In this perspective, the use of organic rich lake sediment - sapropel - as a binding material in line with other environmentally friendly filling materials can be considered as a challenge. Sapropel itself is a valuable resource with multiple areas of application, for example, medicine, veterinary, agriculture, livestock farming, balneology, cosmetic applications, construction, and its application options have been widely studied in the 20th century in the Baltic countries, Ukraine and Russia. Birch wood fibre and sanding dust, hemp shives, ‘Aerosil’ are used as a filler and three types of sapropel are used as a binder in making composites. After material preparation and curing, physical and mechanical properties - density, thermal conductivity, compressive and flexural strength, were determined and compared to the data in the literature, and the opportunities to use them in the ecological construction were considered. The obtained results give insight into possibilities to use sapropel as a raw material, which can be considered as prospective material for construction materials and design products.

    2016-04-26

    Electromagnetic generators (EMGs) and triboelectric nanogenerators (TENGs) are the two most powerful approaches for harvesting ambient mechanical energy, but the effectiveness of each depends on the triggering frequency. Here, after systematically comparing the performances of EMGs and TENGs under low-frequency motion (harvested energy is wasted. In contrast, a TENG has an output voltage that is usually high enough (>10-100 V) and independent of frequency so that most of the generated power can be effectively used to power the devices. Furthermore, a TENG also has advantages of light weight, low cost, and easy scale up through advanced structure designs. All these merits verify the possible killer application of a TENG for harvesting energy at low frequency from motions such as human motions for powering small electronics and possibly ocean waves for large-scale blue energy.

  6. Gaseous Radiochemical Method for Registration of Ionizing Radiation and Its Possible Applications in Science and Industry

    CERN Document Server

    Lebedev, S G

    2005-01-01

    This work presents a new possibility of registration of ionizing radiation by the flowing gaseous radiochemical method (FGRM). The specified method uses the property of some solid crystalline lattice materials for a free emission of radioactive isotopes of inert gas atoms formed as a result of nuclear reactions. Generated in an ampoule of the detector, the radioactive inert gases are transported by a gas-carrier into the proportional gas counter of the flowing type, where the decay rate of the radioactive gas species is measured. This quantity is unequivocally related to the flux of particles (neutrons, protons, light and heavy ions) at the location of the ampoule. The method was used to monitor the neutron flux of the pulsed neutron target "RADEX" driven by the linear proton accelerator of INR RAS. Further progress of the FGRM may give rise to possible applications in nuclear physics, astrophysics and medicine, in the nondestructive control of fissionable materials, diagnostics of thermonuclear plasma, monit...

The favorite phase composition of this material due to low combustion temperature of 850 grad C exhibits very good cementitious properties. Fluidized ashes may be preferably used in the production of some types of Portland cements as a gypsum replacement and in cement-free concretes. The quality tests of this sulfo-calcareous material are proposed as well as some application possibilities. (authors)

  11. Possible applications of neutron activation analysis at the RB reactor for the environmental monitoring

    International Nuclear Information System (INIS)

    This paper presents the possibilities of performing neutron activation analysis in Yugoslavia for the purpose of environmental pollution monitoring. Neutron activation analysis (NAA) is an established method for the determination of trace elements in a broad range of samples. It is non-destructive method used in a routine manner with gamma-ray spectrometry for various applications in biology, environmental toxicology, radiation assessment, mineral exploration, trace elements monitoring regarding human health studies. As a complex, powerful analytical tool, it might give results even when other analytical methods fail. NAA has been performed at the Nuclear Engineering Laboratory (NET), the VINCA Institute of Nuclear Sciences, for various applications in the reactor physics research. The samples are irradiated in the RB research reactor, which is the zero-power, bear, heavy water critical facility utilising three fuel element types. The reactor system is very flexible and allows for different core configurations, resulting in various neutron fields, with energy spectra ranging from thermal to fast (in the coupled fast-thermal system HERBE). There are several vertical and horizontal experimental channels available for sample's irradiation. The achievable thermal neutron flux is approximately 1 0 7 n/(cm 2 s) per 1 W of fission power. We believe the RB reactor could be successfully used for neutron activation analysis of trace elements in the environmental samples, comprising short-lived isotopes. Although the flux level and restricted irradiation time pose a certain limitation to NAA applications at the RB reactor, it can be compensated by the specific methodology advancement. That involves overcoming the main sources of error in the instrumental NAA evaluation methodology which utilises generally valid k0, and Q0 factors. In particular, the computational accuracy of required nuclear parameters (e.g. neutron flux distribution, effective nuclear cross sections) can be

  12. Design criteria for a high energy Compton Camera and possible application to targeted cancer therapy

    International Nuclear Information System (INIS)

    The proposed research focuses on the design criteria for a Compton Camera with high spatial resolution and sensitivity, operating at high gamma energies and its possible application for molecular imaging. This application is mainly on the detection and visualization of the pharmacokinetics of tumor targeting substances specific for particular cancer sites. Expected high resolution (< 0.5 mm) permits monitoring the pharmacokinetics of labeled gene constructs in vivo in small animals with a human tumor xenograft which is one of the first steps in evaluating the potential utility of a candidate gene. The additional benefit of high sensitivity detection will be improved cancer treatment strategies in patients based on the use of specific molecules binding to cancer sites for early detection of tumors and identifying metastasis, monitoring drug delivery and radionuclide therapy for optimum cell killing at the tumor site. This new technology can provide high resolution, high sensitivity imaging of a wide range of gamma energies and will significantly extend the range of radiotracers that can be investigated and used clinically. The small and compact construction of the proposed camera system allows flexible application which will be particularly useful for monitoring residual tumor around the resection site during surgery. It is also envisaged as able to test the performance of new drug/gene-based therapies in vitro and in vivo for tumor targeting efficacy using automatic large scale screening methods

    Full Text Available In our article we deal with the problematics of focus groups and their implementation in kinantropological research. The primary target of an analysis of electronic information resources of the Palacky University was to look up research projects built upon the of focus group metodology. The analysis of accessible articles put forward that particularly in the field of kinantropological research, the method is used scarcely. The main objective of our article was to introduce the focus group as a valuable research method and outline the potential applications in kinantropology. On the basis of the summarized information on focus groups research we concluded that the focus groups may represent an effective tool for capturing such phenomenons as the affect of social environment, subcultural aspects, or self efficacy on development of attitudes to lifelong learning in the context of motor activity. The confirmation of the outlined possibilities will be the subject of our further research.

    International Nuclear Information System (INIS)

    Grafting vinyl acetate (VAc) and itaconic acid (IA) comonomer onto polyethylene (PE) and polypropylene (PP) was performed by means of gamma rays. Conditions for the minimum homopolymer formation, maximum grafting yield and alternate copolymer grafts were carried out. The swelling and biocompatibility properties of these copolymers were evaluated for possible application in the field of blood biocompatibility as in medical devices, artificial organs and hemodialysis membranes. The grafted membranes on different irradiation dose showed improved swelling and blood biocompatibility. The presence of functional groups on the membranes reduced protein adsorption and enhanced The swelling and protein low affinity properties of PE-g-(VAc-alt-IA) and PP-g- (VAc-alt-IA) indicate potential use as blood biocompatible membranes

  17. Polydentate chelants on base of 8-hydroxyquinoline and possibilities of their analytical application

    International Nuclear Information System (INIS)

    Binary and heteroligand complex compounds of rare-earth elements have been studied, in which one of the ligands is a polydentate chelating agent, namely, a derivative of 8-hydroxyquinoline, such as 8-hydroxyquinaldoxime, 8-hydroxyquinaldazine, 2- (N-(o-hydroxyphenyl)-formimidoyl]-8-hydroxyquinoline. The most marked differences in the distribution coefficients of elements of the cerium and yttrium subgroups are observed in the case of extraction of rare-earth elements with a chloroform solution of 2-[N-(0-hydroxyphenyl)-formimidoyl]-8-hydroxyquinoline in the presence of Cupferron or benzoylphenylhydroxy amine. The possibility of analytical application of the systems under consideration is shown with a mixture of praseodymium with erbium taken as an example

    Full Text Available Hazardous waste management system as a separate segment includes the transportation of hazardous waste, which specifically includes transportation from the place of its origin to the place of storage, treatment or final disposal. This function includes all forms of transport, but experience has shown that the most used one is a road traffic, which also carries an extremely high risk of possible occurrence of accident and endangering the local community, material resources and environment. Therefore, it is necessary to establish control over transport option, and the risk too, which is achieved by conducting risk assessments and then selecting the optimal transport routes. In each of these phases GIS has found its major application, enabling operation with different types of data, a simplified procedure of multi-criteria analysis and a clear visual representation of the received results. .

  19. Nonlinear Dynamics of Infectious Diseases Transfer with Possible Applications for Tubercular Infection

    Krevchik, V D; Dahnovsky, Yu I; Semenov, M B; Shcherbakova, E V; Yamamoto, Kenji

    2007-01-01

    In this paper, we model a nonlinear dynamics of infectious diseases transfer. Particularly, we study possible applications to tubercular infection in models with different profiles (peak values) of the population density dependence on spatial coordinates. Our approach is based on the well known method of instantons which has been used by the authors to describe kinetics of adiabatic chemical reactions as a function of the heat-bath temperature and other system parameters. In our approach, we use "social temperature" T as one of the controlling parameters. Increase of T leads to acceleration of the infectious diseases transfer. The "blockage" effect for the infectious diseases transfer has been demonstrated in the case when peak values (in the population density) are equal to one and under condition that the "social temperature" is low. Existence of such effect essentially depends from environment "activity" (social and prophylactic). Results of our modeling qualitatively meet the tuberculosis dynamic spread d...

  20. Neutron activation analysis of single human hairs and possible applications for forensic purposes

    International Nuclear Information System (INIS)

    A new analytical procedure that enables to determine more than 10 trace elements in single, 3 cm human hair segments by neutron activation analysis (NAA) was elaborated. Application of a special washing procedure of hair (before irradiation) made possible to lower sodium content by two orders of magnitude without affecting trace element content. After irradiation in the thermal neutron flux of about 1014n.cm-2.sec-1 the activity of hair was measured with 70 cm3Ge(Li) detector coupled to 4000 channel pulse height analyser. As an alternative method, a destructive version of NAA with ion exchange group separation of radionuclides was applied. It was found that sometimes high gradients of element concentration along the hair length exist and that there is without any doubt a distinct influence of environmental factor on the content of some trace elements in hair. The criminalistic aspects of hair analysis were also studied using new statistical criterion for elimination (identification). Both possibilities and limitations of the method are discussed.

    1977-09-01

    This report presents the results of a review of the available codes, for application to the National Waste Terminal Storage (NWTS) Program. Consideration was given to the types of radionuclides which may be of concern, the possible modes of release of these radionuclides and the various pathways by which members of the general public in the vicinity of a terminal storage facility may be exposed to the releases. Results reveal that the types and quantities of radioactive material requiring disposal will depend on the type of back and fuel cycle adopted. It can be assumed that under normal operating conditions there will be virtually no liquid effluent and inconsequentially small quantities of radioactive gaseous effluent. Under accident conditions during operation, both liquid and gaseous releases could occur resulting in exposures to the general public. Failure of the facility subsequent to decommissioning could also result in exposures but primarily via the aquatic pathways. A review of three atmospheric dispersion models and 32 environmental dosimetry codes presently used by the nuclear industry was performed. A discussion is presented on standard NRC methodologies for determining the dispersion coefficients used as input to the various models and the inherent limitations of many of the techniques routinely used to evaluate site specific atmospheric dispersion. The review of the dosimetry codes reveals that no one code is generally applicable to the NWTS Program, but some codes permit radiological assessment of the most important exposure pathways. (DLC)

  2. Possibilities of magnet prism β-spectrometer application in on-line experiments

    International Nuclear Information System (INIS)

    The main attention is paid to works with particle beam in up-to-date nuclear investigations. The application of magnet prism β-spectrometer for works in 'on-line' experiments is considered in this article. The source chamber and detector chamber are distanted from each other on great distance (4 m) and are out of operation field of spectrometer. There is a reliable defence of operating field of device from external parasitic fields by the magnetic screens system. The additional advantage is a factor that source (target) and detector could replacing in specific directions about few centimetres during the device operating. The main β-spectroscopic performances of device are compared with Grenoble spectroscopic complex. The liner depression of prism spectrometer account for from 3,6 up to 6 m; light force - from 2·10-4 up to 6·10-4 up to 4π; operating resolving power - 0,02-0,05% by impulse. Investigation range is from several keV up to 3 MeV. There are all opportunities for installing of the on-line magnetic prism spectrometer on the U-150 accelerator and the WWR-K reactor. Spectrometer application in 'on-line' experiments gives possibility to obtain more wide information. 4 refs

    Full Text Available The new ICT technologies are not only fast developed but, in addition, are giving birth to newer systems and tools. The Internet network have become essential communication tools in business processes recently. Using the Internet by means of mobile appliances increases the possibilities. The agriculture has some speciality in information technology. The ICT adoption in the agriculture and main drivers has been examined. For the successful application the key lessons have to understand. To get a draft overview of Hungarian position there is part about it. In this part there are data about household communication devices the individuals ICT usage by age. The region differences in information technologies can be seen also. The final part of the paper there are some technology and application examples. The new devices like tablets and new services like Cloud Computing have great potential in agriculture. Cloud Computing provides better resource management and effective cost control. However, the business assessment of these technologies must not be done only on the basis of the technology and taken out of its environment randomly since the whole area is very complex.

  4. Evaluation of non-destructive testing methods with possible applications in nuclear power concrete constructions

    International Nuclear Information System (INIS)

    Non-destructive Testing (NDT) has been applied in several Swedish nuclear power plant projects in the last ten year period. It is assumed that the results in these projects are similar. Before continuing with further development this survey of available reports is performed. The reader must be aware that NDT of concrete is presently poorly developed in Sweden and that we are aware that intense development is taking place abroad. Here, it is not yet widely recognized that NDT is necessary, if we shall be able to economically maintain ageing concrete structures. Experience from conventional testing of cores, removed from a nuclear reactor containment in Finland, show that there is a 100% variation in strength - thus there is no possibility to assign general values to concrete strength. Instead it is necessary to find the local errors or degradations. To do this it is difficult to see any other possibilities than assessment based on NDT. Assessment is the application of different techniques, like NDT, at a specific point and time in order to calculate the state of the detail relative the original design. Monitoring, in contrast, means that the structure is continuously supervised along the axis of time which allows the detection of events. The level of security is thus elevated by monitoring and this should have as consequence that safety factors or coefficients of variation can be set lower. The time series created by monitoring are of great value for the possibility of future generations to evaluate ageing constructions. The purpose of this report is to give recommendations regarding which NDTmethods are suitable for practical application and which should be selected for further development, provided that the results are intended to be used in calculations, that will result in the remaining service-life of the plant. In order to do this the engineer has to determine the as-built conditions, local concrete strength, fissures, rebar corrosion, delamination and losses

    Hydrothermal decomposition of slate (building materials) containing asbestos has been attempted by using a NH4H2PO4 solution. Firstly, the alteration of chrysotile as a starting material was investigated under hydrothermal conditions of 200° C, 12 hrs of reaction time and with a phosphate solution. It was confirmed that the original fibrous form of chrysotile had been perfectly collapsed by the SEM observation. The chrysotile (asbestos) disappeared to form Mg-Ca-Silicate (Ca7Mg2P6O24) estimated by XRD. The composition and chemical form of reaction products (Mg-Ca-Silicate) was predicted to application as a fertilizer. Fertilizer effect of these resulted product on cultivations of Japanese radish (leaves), soybeans and tomatoes, was examined by using a special medium of mixed soil with a low content of N, P, K and a thermal-treated zeolite one. The fertilizer effects of the product were compared to commercial fertilizers such as N, N-K-P and P types. In order to estimate the fertilizer effect, the size of crops, number of fruits and number of leaves were measured everyday. As a result, these hydrothermal products of slate containing asbestos were as good as commercial fertilizers on the market. Fruits groups especially had a good crop using the hydrothermal slate product. These results show that the main components of hydrothermal treatments slate are calcium silicate and magnesium phosphate. Its decomposition reaction products may have the possibility of application for fertilization of crops which require nucleic acid—phosphorus.

    Industrial wastes with a high iron or aluminium oxide content are produced in huge quantities as by-products of water treatment (water treatment residuals), bauxite processing (red mud) and hard and brown coal burning in power plants (fly ash). Although they vary in their composition, the wastes have one thing in common--a high content of amorphous iron and/or aluminium oxides with a large specific surface area, whereby this group of wastes shows very good adsorbability towards heavy metals, arsenates, selenates, etc. But their physical form makes their utilisation quite difficult, since it is not easy to separate the spent sorbent from the solution and high bed hydraulic resistances occur in dynamic regime processes. Nevertheless, because of the potential benefits of utilising the wastes in industrial effluent treatment, this issue attracts much attention today. This study describes in detail the waste generation processes, the chemical structure of the wastes, their physicochemical properties, and the mechanisms of fixing heavy metals and semimetals on the surface of iron and aluminium oxides. Typical compositions of wastes generated in selected industrial plants are given. A detailed survey of the literature on the adsorption applications of the wastes, including methods of their thermal and chemical activation, as well as regeneration of the spent sorbents, is presented. The existing and potential ways of modifying the physical form of the discussed group of wastes, making it possible to overcome the basic limitation on their practical use, are discussed.

    1988-12-01

    Superconducting tunneling junctions (STJ) have been demonstrated to be sensitive detectors for X-rays at energies of 6 keV. The measured energy resolution for Sn/Sn-oxide/Sn junctions (75 × 75 μm2) at an operating temperature below 0.5 K is 65 eV (FWHM) at an energy of 5.89 keV. An extrapolation to vanishing electronic noise yielded a resolution of 40 eV. This improved energy resolution compared to conventional semiconductors is due to the thousand times smaller energy gap of a superconductor. The mechanisms of the detector is the production of excess quasiparticles (single particle electronic excitations) by the breaking of Cooper pairs (condensed electronic ground state). These excess quasiparticles tunnel across the insulating barrier owing to the quantum mechanical tunneling effect. The additional current is integrated by means of a charge sensitive preamplifier. The basic physics of the detector is presented and possible applications in astrophysics are discussed. Present address: Institut de Physique, Rue A.-L. Breguet 1, CH-2000 Neuchâtel, Switzerland.

    Full Text Available Factoring is the contract negotiated continuous purchase of short-term debts, incurred by supplier due to the provision of unsecured credit supply. Factoring is a method of financing that can offer a lot to businesses, especially with its added value. This method mainly includes protection before customers’ insolvency, management of receivables, as well as the opportunity to dispose with the funds before the end of the maturity of receivables. Forfeiting is the purchase of export receivables on credit at the time of delivery. It is related to receivables with the future maturity denominated in freely convertible currency, and secured with a bank aval bill, letter of credit with deferred payment or a bank guarantee. The conditions, under which each company provides forfeiting, depend essentially on the creditworthiness of the applicant and customer, as well as creditworthiness of the bank that issued the payment instrument. The aim of the present paper is to analyze the factoring and forfeiting market in Slovakia and based on the analysis of this issue to propose and verify theoretical and practical possibilities of factoring and forfeiting financing in the selected wood-working company with the estimation of costs associated with their use.

    Full text: X-rays have been for already longer than a century the instrument of choice when producing images of opaque objects. One important characteristic of the use of X-rays as an imaging tool is the geometrical arrangement in which the object under study is placed between the photons source and the imaging material (film or electronic device). This set-up cannot be realized in a multitude of situations of industrial interest. In those cases the source and the imaging device are limited to be at the same side of the object rendering impossible the use of present day's possibilities of X-ray imaging. It is in these cases where the technique discussed exhibits most of its power and advantages. By using the back-to-back emitted gamma-rays of the positron-decay of {sup 22}Na, the Gamma-Ray Compton Backscattering (GRCB) technique is able of building images of an object placed in front of the gamma-rays source. The set-up includes two detectors connected in time coincidence, one of them, a pixelated position- detector in charge of building the image and the other just providing the gating condition. The talk explains the working principle, shows some first images of hidden objects in soil, and discusses some of the prospective areas of application like oil industry and explosive landmines localization.

  11. A New Algorithm for Identifying Possible Epidemic Sources with Application to the German Escherichia coli Outbreak

    Directory of Open Access Journals (Sweden)

    Roberto Benzi

    2013-03-01

    Full Text Available In this paper we describe a recently developed algorithm called Topological Weighted Centroid (TWC. TWC takes locations of an event of interest and analyzes the possible associated dynamics using the ideas of free energy and entropy. This novel mathematical tool has been applied to a real world example, the epidemic outbreak caused by Escherichia coli that occurred in Germany in 2011, to point out the real source of the outbreak. Other four examples of application to other epidemic spreads are described: Chikungunya fever of 2007 in Italy; Foot and mouth disease of 1967 in England; Cholera of 1854 in London; and the Russian influenza of 1889–1890 in Sweden. Comparisons have been made with other already published algorithms: Rossmo Algorithm, NES, LVM, Mexican Prob. The TWC results are significantly superior in comparison with other algorithms according to four independent indexes: distance from the peak, sensitivity, specificity and searching area. They are consistent with the idea that the spread of infectious disease is not random but follows a progression based on inherent, but as yet undiscovered, mathematical laws. The TWC method could provide an additional powerful tool for the investigation of the early stages of an epidemic and novel simulation methods for understanding the process through which a disease is spread.

  13. Application possibilities for nuclear heating plants in the energy system of the Federal Republic of Germany

    International Nuclear Information System (INIS)

    The field of application for nuclear heating plants is the so-called low-temperature heating market. It includes the energy demand for space heating, hot water an low-temperature process heat. The analysis of technical potentials for heating reactors considers two different levels. The structure of the district heating system determines the technical potential in the now existing energy system, it amounts to a total power of 9,8 to 14,3 GWth of heating reactors. For a possible extended use of heating reactors in future which goes beyond the existing district heating system the technical circumstances and the local distribution of the low-temperature heating market define the technical potential which ranges from 126 to 160 GWth on todays basis. The chance of implementing nuclear heating plants is strongly influenced by the economy of their heat generation. The economic situation of heat generation with heating reactors is estimated in comparison to current fossil district heating production systems. In the low-temperature heating market the heat supply by nuclear fed district heating systems is compared to the heat production in houses. Considering the assumptions the analysis indicates that nuclear heating plants can compete with existing fossil heat sources. The analysis shows that heating reactors are an interesting and powerful option for the supply of the district heating market in future. The underlying economic assumptions would allow the use of nuclear heating plants and it seems that they could contribute to reduce the environmental stress. (orig.)

    An increase in the efficiency of sampling from Boltzmann distributions would have a significant impact on deep learning and other machine-learning applications. Recently, quantum annealers have been proposed as a potential candidate to speed up this task, but several limitations still bar these state-of-the-art technologies from being used effectively. One of the main limitations is that, while the device may indeed sample from a Boltzmann-like distribution, quantum dynamical arguments suggest it will do so with an instance-dependent effective temperature, different from its physical temperature. Unless this unknown temperature can be unveiled, it might not be possible to effectively use a quantum annealer for Boltzmann sampling. In this work, we propose a strategy to overcome this challenge with a simple effective-temperature estimation algorithm. We provide a systematic study assessing the impact of the effective temperatures in the learning of a special class of a restricted Boltzmann machine embedded on quantum hardware, which can serve as a building block for deep-learning architectures. We also provide a comparison to k -step contrastive divergence (CD-k ) with k up to 100. Although assuming a suitable fixed effective temperature also allows us to outperform one-step contrastive divergence (CD-1), only when using an instance-dependent effective temperature do we find a performance close to that of CD-100 for the case studied here.

  16. Results of Clinical Application of Scintillation Scanning of the Spleen on 500 Patients: Possibilities and Limits

    International Nuclear Information System (INIS)

    After injecting erythrocytes marked with radioactive substances and artificially damaged there is a rapid clearance of these cells from the blood-stream and sequestration in the spleen. The resultant high concentration of radioactivity in the spleen permits a good scintigraphic demonstration of the organ. For many reasons Na2Cr51O4 seems at present to be the most suitable substance for labelling erythrocytes, and alteration by heat the most practical means of damaging the cells. The systematic application of spleen scintigraphy on over 500 patients showed the following indications for this method: (1) Demonstration of enlargement of the spleen is not possible by clinical or roentgenological methods; (2) Verification of tumours in the upper left abdominal region; (3) Demonstration of accessory spleens after splenectomy; (4) Demonstration of ectopic spleens (situs inversus, ptosis); (5) Demonstration of parenchymal defects in the spleen (e.g. intrasplenic bleeding, infarcts of the spleen, necrosis of the spleen and intrasplenic cysts). By planimetric measurements of the scintigram area and by calculating the ''splenic surface area index'' (= scintigram area/body surface of the patient) a good quantitative estimation of the extent of spleen enlargement may be obtained. In healthy persons the surface area of the scintigram does not exceed 70- 80 cm2 and the splenic surface-area-index lies normally within 2.5 - 4.5 x 10-3. A comparison with the clinical findings showed that only one third of the spleens which were found by scintigraphy to be positively enlarged could be detected by percussion and palpation. In various diseases the clinical estimation.of spleen enlargement is false in an even higher percentage of the cases. Only when the spleen has completely lost the ability to sequestrate heat- altered erythrocytes is the scintigraphic depiction of the spleen impossible. Such cases, however, seem to be extremely rare; we have so far observed only one. Up to now the

  15. A survey of direct inversion methods having possible application to tunnel detection

    International Nuclear Information System (INIS)

    Within recent years there has been considerable interest in the development of geophysical methods for the location of hidden underground tunnels and cavities. Consideration of this problem has been motivated by military applications, such as the detection of shallow man-made tunnels and arm caches, as well as civilian applications such as detection of limestone cavities in karst terrain and the mapping of abandoned mine workings. There are also applications for in-situ coal gasification and for the monitoring of nuclear waste disposal sites. The most reliable method presently used to map these underground anomalies has been direct detection by closely spaced drilling. However, the high cost of drilling renders this method impractical except for detailed and localized mapping, and certainly unfeasible for any type of broad-scale reconnaissance activity. Largely motivated by petroleum and mineral exploration needs, however, the seismic industry has seen a virtual revolution in acquisition and processing techniques within the past ten years. Paralleling these developments have been corresponding developments in acoustical imaging and non-destructive testing. Researchers in the field of inverse scattering have produced a number of new methods for target imaging from backscattered reflection data

    The nanofiltration system has many potential uses in removing chemical and biological contaminants from water. - During the last decade, nanofiltration (NF) made a breakthrough in drinking water production for the removal of pollutants. The combination of new standards for drinking water quality and the steady improvement of the nanofiltration process have led to new insights, possible applications and new projects on lab-scale, pilot scale and industrial scale. This paper offers an overview of the applications in the drinking water industry that have already been realised or that are suggested on the basis of lab-scale research. Applications can be found in the treatment of surface water as well as groundwater. The possibility of using NF for the removal of hardness, natural organic material (NOM), micropollutants such as pesticides and VOCs, viruses and bacteria, salinity, nitrates, and arsenic will be discussed. Some of these applications have proven to be reliable and can be considered as known techniques; other applications are still studied on laboratory scale. Modelling is difficult due to effects of fouling and interaction between different components. The current insight in the separation mechanisms will be briefly discussed

    Tanaka, H. K. M.; Watanabe, H.

    2014-04-01

    Despite the latent and unique benefits of imaging uranium and thorium's distribution in the earth's interior, previously proposed experimental techniques used to identify the incoming geo-neutrino's direction are not applicable to practical imaging due to the high miss-identification in a neutrino's track reconstruction. After performing experimental studies and Monte-Carlo simulations, we confirmed that a significant improvement is possible in neutrino tracking identification with a 6Li-loaded neutrino detector. For possible imaging applications, we also explore the feasibility of producing geo-neutrinographic images of gigantic magmatic reservoirs and deep structure in the mantle. We anticipate and plan to apply these newly designed detectors to radiographic imaging of the Earth's interior, monitoring of nuclear reactors, and tracking astrophysical sources of neutrinos.

In radiation protection field, detriment is related with human health or expenses, and varying parameter is level of radiation protection (for example dimensions of the installed shielding). The problem lies in fact that for the given value of the varying shielding parameter the maximum benefit and the minimum detriment are not achievable simultaneously because the greater benefit includes the greater expense. The problems which have to be solved because of introducing Dose Limitation System, in regard to create Modified Dose Limitation System, are presented. (author)

    We have prepared transparent films with a sheet relativity of 10(exp 1) to 10(exp 12) ohm/square by co-depositing a transparent conducting oxide (TCO) with magnesium fluoride, using two independently controlled RF magnetron sputter guns to facilitate adjustment of the film composition, Co-deposited indium tin oxide (ITO) and MgF2 on quartz and flexible polymeric substrate exhibited reasonably stable sheet resistivity over several months' time, with substantially lower optical reflectance than that of pure ITO. However, exposure to low-intensity blue light reduces sheet resistivity by as much as two orders of magnitude. Our results suggest this photoconductivity effect may be present in all InO(x)-based materials. We find that sheet resistivity can by "tuned" by admitting a small amount of high-purity air during deposition offering the possibility of closed loop process control.

    2015-01-01

    Context. A possible correlation between CO luminosity (L_CO ) and its line width (FWHM) has been suggested and denied in the literature. Such claims were often based on a small, or heterogeneous sample of galaxies, and thus inconclusive. Aims. We aim to prove or dis-prove the L_CO -FWHM correlation. Methods. We compile a large sample of submm galaxies at z>2 from the literature, and investigate the L_CO-FWHM relation. Results. After carefully evaluating the selection effects and uncertainties such as inclination and magnification via gravitational lensing, we show that there exist a weak but significant correlation between L_CO and FWHM. We also discuss a feasibility to measure the cosmological distance using the correlation.

    In situ hybridization with radioactively labeled probes will be described, and the effect of different hybridization conditions will be demonstrated. Hybridizations were performed on different types of human cells with various DNA probes. Repetitive sequences were labeled with one nucleotide, namely /sup 3/H dTTP, while for single copy sequences the sensitivity was increased by using probes with three or four labeled nucleotides. Applications include, for example, the localization of cloned DNA sequences to specific chromosomal subregions. In addition, they have used chromosome-specific DNA probes to identify the number and position of the respective chromosomal domain in interphase nuclei. This approach can be used to investigate the chromosome topography in normal and aberrant cells.

  20. Chemical modification of cobalt ferrite nanoparticles with possible application as asphaltene flocculant agent

    International Nuclear Information System (INIS)

    Asphaltenes can cause enormous losses in the oil industry, because they are soluble only in aromatic solvents. Therefore, they must be removed from the petroleum before it is refined, using flocculant agents. Aiming to find new materials that can work as flocculant agents to asphaltenes, cobalt ferrite nanoparticles were chemically modified through acid-base reactions using dodecylbenzene sulfonic acid (DBSA) to increase their lipophilicity. Nanoparticle synthesis was performed using the co-precipitation method followed by annealing of these nanoparticles, aiming to change the structural phase. Modified and unmodified nanoparticles were tested by FTIR-ATR, XRD and TGA/DTA. In addition, precipitation onset of the asphaltenes was performed using modified and unmodified nanoparticles. These tests showed that modified nanoparticles have a potential application as flocculant agents used to remove asphaltenes before oil refining, since the presence of nanoparticles promotes the asphaltene precipitation onset with the addition of a small amount of non-solvent (author)

  1. Possible applications and characteristics of HTGRs used for industrial co-generation

    International Nuclear Information System (INIS)

    The paper contains an overview of the HTGR's applications - high potential heat needs for industrial processes, covering a temperature range of approximately 500 to 1000 deg. C and higher are described, encompassing processes such as methane steam conversion, ammonia production, complex process of steam coal gasification, hydrogen production and coal hydrogenation for liquid synthetic fuel production, direct iron reduction etc. These needs are to be met by a reactor with power ranging from 1 to 10 GW(th). The USSR R and D work on high-temperature gas-cooled reactors is focused on the standardization of reactor components, high reliability and corresponding high NPP availability and safety. The main effort of the first experimental use of USSR HTGR units is concentrated on the steam conversion of methane. Other industrial processes will be studied at further stages of the HTGR development. (author)

  2. The possibilities of personal albedo neutron dosemeter application at the Slovak cyclotron laboratory

    International Nuclear Information System (INIS)

    In addition to the production of short-lived radioisotopes, the Slovak Cyclotron Laboratory is also engaged in the application of neutron capture therapy, radiotherapy with fast neutrons, and proton therapy. Experiments were carried out where the operating quantities and conversion factors between the neutron fluence and the spatial or personal dose equivalent were determined by Bonner spectrometry over the entire range of energies used, employing a set of moderators. To obtain the requisite dosimetric parameters of the (n,γ) radiation fields, the deconvolution process (statistical regularization) was modified into a rather simple procedure, tractable by using a conventional PC AT. Calibration measurements were employed to obtain the dependence of the sensitivity of albedo dosemeters on the neutron dose ratios in two positions of the dosemeter (on the front and rear sides)

  3. A glorious, yet almost forgotten, mathematical theory, and some possibly new applications of it to physics

    International Nuclear Information System (INIS)

    Hardly the role and the importance of Classical-Invariant Theory is the history of mathematics (say, between - 1850 and - 1920) can be fully appreciated by a nonspecialist. In this study, it was firstly purposed to provide a compact sketch of its foundations starting from (and keeping the framework of) some very basic ideas in the equation theory; and then, after reviewing a couple of classical examples, to illustrate a number of (presumably new) applications to physics, with special reference to constitutive relations in continuous material media. As a significant example of the latter type (amongst other ones), it shall be completely worked out the problem of the a priori structure of linear viscous-stress tensor in a magnetoplasma

  4. Magnetocaloric cycle with six stages: Possible application of graphene at low temperature

    International Nuclear Information System (INIS)

    The present work proposes a thermodynamic hexacycle based on the magnetocaloric oscillations of graphene, which has either a positive or negative adiabatic temperature change depending on the final value of the magnetic field change. For instance, for graphenes at 25 K, an applied field of 2.06 T/1.87 T promotes a temperature change of ca. −25 K/+3 K. The hexacycle is based on the Brayton cycle and instead of the usual four steps, it has six stages, taking advantage of the extra cooling provided by the inverse adiabatic temperature change. This proposal opens doors for magnetic cooling applications at low temperatures

    Full Text Available This paper proposes a new service system that explains the process of social innovation (SI in education in a developing country. We selected 17 Ashoka cases in the field of education in Bangladesh and analyzed them thematically. Results show that targets for SI (educational opportunities, employment opportunities, and additional educational resources are related to the first phase of SI where social entrepreneurs foster innovative ideas that effectively solve social problems. Results also reveal that support for innovation is related to the second phase of SI, in which the SI becomes a social norm. Applying the process, the paper proposes a design of a new SI through the application of massive open online courses (MOOCs to teach financial literacy to poor people.

  8. Theoretical demonstration of the hybrid focusing points of sonic crystal flat lenses and possible applications

    International Nuclear Information System (INIS)

    We demonstrate the hybrid focusing points of sonic crystals for a multi-source array applied to flat sonic crystal lenses. The contributions of different point source couples form hybrid focusing points. Ray-trace analyses are conducted for acoustic flat lenses with multi-source configurations. The finite-difference time-domain (FDTD) simulation of flat lenses with multi-source configurations demonstrates the establishment of pure and hybrid focusing points in a pyramidal constellation. The number of focusing points in the pyramidal constellation depends on the number of point sources. We propose an acoustic device for fine-tuning the location of a far-field hybrid focusing point and discuss its benefits for acoustic energy focusing application

    We have constructed a stacked detector system operating in the X-ray range from 0.5 keV to 250 keV that consists of a Si-based 64×64 DePFET-Matrix in front of a CdTe hybrid detector called Caliste-64. The setup is operated under laboratory conditions that approximate the expected environment of a space-borne observatory. The DePFET detector is an active pixel matrix that provides high count-rate capabilities with a near Fanolimited spectral resolution at energies up to 15 keV. The Caliste-64 hard X-ray camera consists of a 1mm thick CdTe crystal combined with very compact integrated readout electronics, constituting a high performance spectro-imager with event-triggered time-tagging capability in the energy range between 2 keV and 200 keV. In this combined geometry the DePFET detector works as the Low Energy Detector (LED) while the Caliste-64 - as the High Energy Detector (HED) - detects predominantly the high energetic photons that have passed the LED. In addition to the individual optimization of both detectors, we use the setup to test and optimize the performance of the combined detector system. Side-effects like X-ray fluorescence photons, electrical crosstalk, and mutual heating have negative impacts on the data quality and will be investigated. Besides the primary application as a combined imaging detector system with high sensitivity across a broad energy range, additional applications become feasible. Via the analysis of coincident events in both detectors we can estimate the capabilities of the setup to be used as a Compton camera and as an X-ray polarimeter - both desirable functionalities for use in the lab as well as for future X-ray missions.

  10. Optimization of radiation protection and the possible application of fuzzy set theory

    International Nuclear Information System (INIS)

    One important component of the basic principles of radiation protection, termed the optimization of protection, is the decision aiding approach suggested for implementing the basic recommendation of radiation protection that all exposures be kept as low as reasonably achievable, economic and social factors being taken into account (the ALARA principle). In many systems of optimization, and particularly those in which economic and social factors are involved and human beings participate, much of the information on the goals, constraints and impacts of possible human judgement is often of a subjective and imprecise nature. This type of uncertainty, which differs from random uncertainty, requires special mathematical tools for its description. Fuzzy set theory is an attempt to provide such tools for the consideration of subjective uncertainties in human judgement, decision analysis and optimization. Some methods of optimization in a fuzzy environment and decision making with fuzzy information are reviewed, and problems of optimization associated with radiation protection are discussed. Some examples of indirect or implicit optimization introduced into radiation protection at the time of siting of nuclear facilities in Japan are introduced briefly, in view of the difficulty of gaining public acceptance for explicit optimization based on cost-benefit analysis.

    Full Text Available As a contribution to DUS testing within the system of protection of plant breeders' rights (PBR, the AFLP molecular system has been used in this study to produce DNA fingerprinting profiles. DNA polymorphism and genetic distance of nine agronomicaly important maize genotypes has been investigated using the AFLP technique. Two specific adapters, two preselective primers and twenty selective primers were utilized for DNA amplification. The selective primers were GC rich, each having a 3-mer selective sequence at 3' termini. Ten double stranded primer combinations were made out of the twenty primers but only five of them turned out to be reliable. Out of 253 amplified DNA fragments, 177 were polymorphic (70%. The CGA/GAG (B primer combination has proved to be the most polymorphic (44 polymorphic fragments have been recorded revealing the polymorphism rate of 81.5%. Genotypes g1 and g7 were most distinct (GD=55% and GD=79%, respectively and genotypes g1. g4 and g8 were closest (GD=55% in all cases. The paper discusses possible uses of AFLP DNA profiling technique to achieve a unique fingerprinting pattern of agronomicaly important maize genotypes.

  12. Biogenic oxides from neutrophilic iron bacteria and possibilities for application in the nanotechnology

    International Nuclear Information System (INIS)

    The aim of this study is to obtain and characterize the ferric oxides/(oxy)hydroxides formed after cultivation of bacteria under laboratory conditions. The pure cultures of these bacteria isolated from natural habitats are identified by the methods of classical and molecular taxonomy as strains of the Leptothrix genus. Adler (AM) and Silicon iron glucose peptone (SIGP) media are the most appropriate ones for obtaining the iron oxides. The characterization of the oxides and sheaths is performed by different physical methods. The sheaths are formed in a SIGP medium. Light micrograph images and SEM revealed the average size and diameter of the sheaths. The XRD measurements showed the composition of the oxides obtained, as well as the average size of the iron particles (up to 30 nm). The TEM micrographs showed the shape of the biogenic nanoparticles, while the magnetic measurements demonstrated the superparamagnetic character of the magnetic part of the biomaterials. The new biogenic materials are promising for application in magneto electronic for building biosensors

    2016-08-01

    This work presents a bacteria-based bead for potential self-healing concrete applications in low-temperature marine environments. The bead consisting of calcium alginate encapsulated bacterial spores and mineral precursor compounds was assessed for: oxygen consumption, swelling, and its ability to form a biocomposite in a simulative marine concrete crack solution (SMCCS) at 8 °C. After six days immersion in the SMCCS the bacteria-based beads formed a calcite crust on their surface and calcite inclusions in their network, resulting in a calcite–alginate biocomposite. Beads swelled by 300% to a maximum diameter of 3 mm, while theoretical calculations estimate that 0.112 g of the beads were able to produce ∼1 mm3 of calcite after 14 days immersion; providing the bead with considerable crack healing potential. The bacteria-based bead shows great potential for the development of self-healing concrete in low-temperature marine environments, while the formation of a biocomposite healing material represents an exciting avenue for self-healing concrete research.

    In recent times, the transportation industry has generated a number of developments involving new technology in signaling. Important developments have involved the production of light by means of light emitting diode (LED). Since the heat from the junction must be dissipated into the ambient somehow, changing the ambient temperature affects the junction temperature and hence the emitted light. When the LEDs have been used in the railway or traffic signals, the optical proprieties of these have to maintain more rigorous specifications. The junction temperature of the power LEDs affects the device's luminous flux of the device. To develop signals, using LED as light source, able to respect intensity specifications it is not simple. In fact, then shift in intensity, over the specified temperature range, can be greater than the magnitude of specification. In this paper, we describe problems of the temperature dependent changes of LED intensity. Besides we will introduce an innovative technical to allow the use of the LEDs in applications with rigorous specifications.

    Computed tomography (CT) data provide information for volumetric and radiographic density analysis. The present study investigated the application of virtual CT volumetry of the tarsal bones to estimation of the sex, stature, and body weight using postmortem CT (PMCT) data of forensic autopsy cases. Three-dimensional (3D) images of the bilateral foot bones of intact Japanese subjects after adolescence (age ≥ 15 years, n = 179, 100 males and 79 females) were reconstructed on an automated CT image analyzer system. Measured parameters were mass volume, mean CT value (HU), and total CT value of the talus and calcaneus. Mean CT values of these bones showed age-dependent decreases in elderly subjects over 60 years of age for both sexes, with significant sex-related differences especially in the elderly. The mass volumes and total CT values of the talus and calcaneus showed significant sex-related differences, and also moderate correlations with body height and weight for bilateral bones in all cases (r = 0.58-0.78, p forensic identification; however, greater variations should be considered in body weight estimations of females.

    We present here a comprehensive study of the light yield of primary and secondary scintillations produced in gaseous and liquid Ar in the near infrared (NIR) and visible region, at cryogenic temperatures. The measurements were performed using Geiger-mode avalanche photodiodes (GAPDs) and pulsed X-ray irradiation. The primary scintillation yield of the fast emission component in gaseous Ar was found to be independent of temperature in the range of 87-160 K; it amounted to 17000+/-3000 photon/MeV in the NIR in the range of 690-1000 nm. In liquid Ar at 87 K, the primary scintillation yield of the fast component was considerably reduced, amounting to 510+/-90 photon/MeV, in the range of 400-1000 nm. Proportional NIR scintillations (electroluminescence) in gaseous Ar were also observed; their amplification parameter at 160 K was measured to be 13 photons per drifting electron per kV. No proportional scintillations were observed in liquid Ar up to the electric fields of 30 kV/cm. The applications of NIR scintillati...

  18. A method for accurate localization of the first heart sound and possible applications

    International Nuclear Information System (INIS)

    We have previously developed a method for localization of the first heart sound (S1) using wavelet denoising and ECG-gated peak-picking. In this study, an additional enhancement step based on cross-correlation and ECG-gated ensemble averaging (EA) is presented. The main objective of the improved method was to localize S1 with very high temporal accuracy in (pseudo-) real time. The performance of S1 detection and localization, with and without EA enhancement, was evaluated on simulated as well as experimental data. The simulation study showed that EA enhancement reduced the localization error considerably and that S1 could be accurately localized at much lower signal-to-noise ratios. The experimental data were taken from ten healthy subjects at rest and during invoked hyper- and hypotension. For this material, the number of correct S1 detections increased from 91% to 98% when using EA enhancement. Improved performance was also demonstrated when EA enhancement was used for continuous tracking of blood pressure changes and for respiration monitoring via the electromechanical activation time. These are two typical applications where accurate localization of S1 is essential for the results

    Full Text Available Nickel oxide (NiO is a versatile wide band gap semiconductor material. At present, transparent conducting oxide films find application as transparent electrodes and window coatings for opto-electronic devices but most are n-type. However p-type conducting films, of which NiO is one, are required as optical windows for devices where minority carrier injection is required. In this study, nickel (Ni was resistively deposited on glass substrates and oxidised (isochronally in oxygen at temperatures ranging from 300 ˚C to 600 ˚C. The oxidised Ni layers were subsequently characterised using scanning electron microscopy (SEM, X-ray diffraction (XRD and UV-visible photospectrometry in the range 200 nm – 1000 nm. The four point probe method (van der Pauw geometry was used to determine the sheet resistances of the oxidised films. SEM results of the surface revealed a strong dependence of the surface texture and particle size on the oxidation temperature and time. XRD performed on the oxidised Ni indicated progressive transformation from nanograined polycrystalline Ni to NiO at elevated temperatures. Film thicknesses, particle sizes, energy band gap and wavelength-dependent refractive indices were determined from transmission and absorbance data.

  20. Reinforced polyacrylates by UV and EB curing: preparation, structure and possible applications

    International Nuclear Information System (INIS)

    Reinforced polyacrylates were obtained by UV and electron beam (EB) curing using nano-sized silica particles as fillers for acrylates. The surface of the silica was chemically modified to improve embedding of the filler within the acrylate matrix. The modification was done using methacryloxypropyl trimethoxysilane and as product of an acid catalysed condensation of the organosilanes a polysiloxane shell is formed. This shell is linked to the silica via reaction with the surface silanol groups of the silica. The appearance of covalent Si-O-Si-R bonds formed either by the condensation of silanes and / or by the reaction with Si-OH groups on the silica was demonstrated by multinuclear MAS NMR and mass spectroscopy. Typically, an acrylate-nanocomposite formulation contains up to 35 wt.-% of polysiloxane covered nano-sized silica. The polysiloxane shell still carries methacrylate groups, these can copolymerize with acrylates and after UV or EB curing of such a formulation polyacrylate nanocomposites are obtained. These composite materials exhibit markedly improved properties as compared to pure polymers, e.g. an increased modulus and heat resistance, improved scratch and abrasion resistance as well as reduced gas permeabilities. This makes them very promising as coatings for technical applications. (Author)

    Full Text Available In this study, it was aimed that whether the application of precision farming in different field scala and farm input level is economical or not in grain corn production in Çukurova region by using partial budgetting method for examining the variable costs in the period of the years between 2002-2008. The revenue obtained from yield and the minimum saving from fertilizer, pesticide and seeds were compared with precision farming initial costs in order to cover the investment together with economical field sizes. It was ascertained that investment conditions of precision farming have changed and investment has become more attractive in some years during this period. Depending on the variation of the input costs and exchange rate of Euro, input prices have increased and technology prices have decreased, the investment of precision farming have become attractive. Moreover, depending on the variability on field, sensitive analysis was made in + % 5, + % 10, + % 20, + % 50 variable intervals. Using combine systems for 100 ha field size, it was concluded that the costs of precision farming can be covered by 4,01% of yield increase and 12,02% of overall cost decrease in grain corn production in Çukurova in 2008.

    Kohlrausch, Armin; van de Par, Steven

    1999-05-01

    In our natural environment, we simultaneously receive information through various sensory modalities. The properties of these stimuli are coupled by physical laws, so that, e.g., auditory and visual stimuli caused by the same even have a fixed temporal relation when reaching the observer. In speech, for example, visible lip movements and audible utterances occur in close synchrony which contributes to the improvement of speech intelligibility under adverse acoustic conditions. Research into multi- sensory perception is currently being performed in a great variety of experimental contexts. This paper attempts to give an overview of the typical research areas dealing with audio-visual interaction and integration, bridging the range from cognitive psychology to applied research for multimedia applications. Issues of interest are the sensitivity to asynchrony between audio and video signals, the interaction between audio-visual stimuli with discrepant spatial and temporal rate information, crossmodal effects in attention, audio-visual interactions in speech perception and the combined perceived quality of audio-visual stimuli.

    Full Text Available Nitroxides as stabile organic radicals were used initially as spin labels in spectroscopy of electron paramagnetic resonance (EPR with respect to parameters such as pH of an intercellular environment, oxygenation of cells and tissues, fluidity of biological membranes, conformational state and topography of proteins. Nitroxides have also been used in biology and medicine as contrast agents in magnetic resonance imaging (MRI. When their antioxidant activities were discovered, an era of research on the potential utility of these agents began. Nitroxides can modulate the redox state of the cell by participation in oxidation/reduction reactions. Therefore, they are extensively examined in various models of oxidative stress. The antioxidant effect of nitroxides is a result of their ability to catalyze dismutation of superoxide radical (superoxide dismutase-like activity, inhibit lipid peroxidation, prevent Fenton and Haber-Weiss reactions by oxidation of transition metal ions to a higher oxidative state, and confer catalase-like activity on heme proteins. In the present paper the antioxidative mechanisms of nitroxides are presented. The relation between structure, function and the rate of nitroxide reduction inside cells and tissues is also presented. The application of nitroxides in chemoprevention and radioprotection is discussed.

  5. Possible applications of granular media (filtration, coalescence) in circuits of uranium recovery from phosphoric acid

    International Nuclear Information System (INIS)

    The uranium recovery from phosphoric acid poses two more specific problems: the necessity of a good clarification of the phosphoric acid before the extraction by an organic solvent; the necessity of an efficient recovery of the residual solvent in the phosphoric acid, freed from uranium, and if necessary, in the wash water. To solve these problems, the application of granular media can furnish a simple and economical solution, by: filtrating through sand and/or anthracite on the first case; coalescence through sand in the second case. The tests which were carried out on pilot circuits have given the following results: 1) Filtration tests on green acid: the best results were obtained with a maximum filtration speed of 7,5 m/h over a height of 1 m min of anthracite from 1.2 to 2.4 mm, with a lagging which permits the prevention of a temperature drop leading to the precipitation of gypsum; 2) Coalescence applied to green acid, free from uranium: to achieve a residual content of less than 5 mg/l, it is necessary to apply a double coalescence, the first functioning without any chemical reagent, and the second with an injection of a specific cationic polymer; 3) Coalescence applied to the wash solution: washing of the solvent effected in water before the re-extration of the uranium; the treated solution contains from 10 to 20 mg/l of residual solvent on an average and can be re-used practically without any complementary treatment

    Full Text Available Enterocin AS-48 is a circular bacteriocin produced by Enterococcus. It contains a 70 amino acid-residue chain circularized by a head-to-tail peptide bond. The conformation of enterocin AS-48 is arranged into five alpha-helices with a compact globular structure. Enterocin AS-48 has a wide inhibitory spectrum on Gram-positive bacteria. Sensitivity of Gram-negative bacteria increases in combination with outer-membrane permeabilizing treatments. Eukaryotic cells are bacteriocin-resistant. This cationic peptide inserts into bacterial membranes and causes membrane permeabilization, leading ultimately to cell death. Microarray analysis revealed sets of up-regulated and down-regulated genes in Bacillus cereus cells treated with sublethal bacteriocin concentration. Enterocin AS-48 can be purified in two steps or prepared as lyophilized powder from cultures in whey-based substrates. The potential applications of enterocin AS-48 as a food biopreservative have been corroborated against foodborne pathogens and/or toxigenic bacteria (Listeria monocytogenes, Bacillus cereus, Staphylococcus aureus, Escherichia coli, Salmonella enterica and spoilage bacteria (Alicyclobacillus acidoterrestris, Bacillus spp., Paenibacillus spp., Geobacillus stearothermophilus, Brochothrix thermosphacta, Staphylococcus carnosus, Lactobacillus sakei and other spoilage lactic acid bacteria. The efficacy of enterocin AS-48 in food systems increases greatly in combination with chemical preservatives, essential oils, phenolic compounds, and physico-chemical treatments such as sublethal heat, high-intensity pulsed-electric fields or high hydrostatic pressure.

    Dopamine D3 receptors have been pharmacologically engaged in humans since the development of the first antipsychotics and ergot-derivative dopamine (DA) agonists, even without knowing it. These agents were generally non-selective, developed primarily to target D2 receptors. In the last 10 years the understanding of the clinical implication of D3 receptors has been progressing also due to the identification of D3 gene polymorphisms, the use of more selective PET ligands such as [(11)C]-(+)-PHNO and the learning regarding the clinical use of the D3-preferential D2/D3 agonists ropinirole and pramipexole. A new specific neuroplasticity role of D3 receptor regarding dendrite arborisation outgrowth in dopaminergic neurons was also proposed to support, at least in part, the slowing of disease observed in subjects with Parkinson׳s Disease treated with DA agonists. Similar mechanisms could be at the basis of the antidepressant-like effects observed with DA agonists when co-administered with standard of care. Severe adverse event occurring with the use of anti-parkinsonian DA agonists in predisposed subjects, i.e., impulse control disorders, are now suggested to be putatively related to overactive D3 receptors. Not surprisingly, blockade of D3 receptors was proposed as treatment for addictive disorders, a goal that could be potentially achieved by repositioning buspirone, an anxiolytic drug with D3-preferential antagonistic features, or with novel selective D3 antagonists or partial agonists currently in development for schizophrenia. At the moment ABT-925 is the only selective D3 antagonist tested in schizophrenic patients in Phase II, showing an intriguing cognitive enhancing effects supported by preclinical data. Finally, exploratory pharmacogenetic analysis suggested that ABT-925 could be effective in a subpopulation of patients with a polymorphism on the D3 receptor, opening to a possible personalised medicine approach.

  8. Modern light water reactors - EPR and SWR 1000. Present status and possibilities of development and application

    International Nuclear Information System (INIS)

    Framatome ANP has focused its efforts on two development projects in the field of light water reactor technology: the EPR (capacity 1500-1600 MW) and the SWR1000. The main goals pursued in developing the two product lines are: to increase nuclear plant safety even further compared to existing plants and to achieve power generating costs that are competitive with those of fossil-fired power plants. Some key advances made during the development that are particularly characteristic of the EPR and SWR are discussed. For the EPR the main safety systems are: double wall containment, containment heat removal system, four train redundancy for main safeguard systems etc. The physical separation of the systems as regards ventilation as well as by concrete walls rules out the possibility of multiple failures caused by fire, flooding or sabotage. In case od a core-melting accident the specially developed depressurization system reduces primary system pressure to < 20 bar. Various PSA have been conducted resulting in the development of a well-balanced system and component designs and avoiding dominant accident sequences from power and shutdown states.One major feature of the SWR 1000 are the passive safety systems, developed, tested and integrated into the design. They are: Containment cooling condensers for heat removal; Safety Relief Valves; Emergency condensers for heat removal from the RPV; Flooding lines for passive core flooding in the event of a LOCA; Drywell flooding line (core-melt accident). Accidents can be controlled both by active and passive systems. PSA has been also conducted. Some economic aspects are discussed in the paper

  9. Analysis of the nuclear heating reactor and its possible application in seawater desalination

    International Nuclear Information System (INIS)

    In order to mitigate the problems of the energy shortage, environmental pollution caused by coal burning and the transport burden in China, the Institute of Nuclear Energy Technology (INET), Tsinghua University, under the support of the state, began the research and development (R and D) of nuclear heating reactor (NHR), which is one of the national key R and D projects in China since the 1980's. Since a 5MW test NHR was completed in November 1989, a lot of experiments have been carried on the NHR-5. The NHR-200 is developed on the experience gained from the design, construction, start-up and operation of the NHR-5. It is designed with a number of advanced and inherent safety features. The main technical and safety features of NHR-200 are: a vessel type light water reactor with the integrated arrangement, full power natural circulation, self-pressurized performance and dual vessel structure. The hydraulic driving system of the control rods is adopted. The design of the NHR-200 insures that the reactor core can be always covered by coolant at any LOCA conditions and the possibility of rods ejection event is excluded by using hydraulic control rods driving system. The excellent performance of the NHR-200 shows that it is suitable to the coupling with a seawater desalination plant from both technical and economic stand. According to the systematic analysis and comparison of economy, technology and safety, the selected coupling design of desalination plant with the NHR-200 are: the steam generator plus multi-effect distillation (MED) process for single water production and the steam generator plus turbine system plus MED process for cogeneration of water-electricity. The economic analysis based on the above mentioned two coupling designs has be conducted. The desalinated water price and its influential factors are determined under present technological circumstances. And some specific proposals of which system to select are given. (author)

  10. Investigation of the possibilities of phosphogypsum application for building partitioning Walls - elements of a prefabricated house

    Rajković Miloš B.

    2002-01-01

    Full Text Available Phosphogypsum is a waste product in the manufacture of phosphoric acid from phosphorite and sulphuric acid by so-called "wet process" and represents a refuse that is as such simply thrown away. Phosphogypsum which is produced by "dihydrating procedure" contains not only various impurties but also radionuclides, which limits its construction use. Performed testings point to the complexity of phosphogypsum structure and composition while the electron microscope's pictures showed its different crystal composition compared to the natural gypsum. The calcined and refined phosphogypsum can be used for partition walls manufacture. To avoid the danger of the possible presence of radionuclides it is better to use the mixture of natural gypsum and phosphogypsum for this purpose. Substantial saving of materials and economic effect can be achieved in this way. The analyse performed in this work have shown significant presence of radionuclides in phosphogypsum. Gammaspectrometric measurements of radioactivity have determined substantial radioactivity of phosphogypsum. Using the maximum tolerated level values that are legally accepted, as well as equations to calculate indexes of tolerated radionuclide presence, an index of 2.23 has been determined for interiors and 1.13 for exteriors, i.e. 0.64 in case of roads. On the basis of the maximum tolerated level of radioactive building materials contamination (< 1, forbiden is the use of phosphogypsum in interiors, allowed (≈ 1 in exteriors and roads. The tests of heavy metal components in phosphogypsum have proved their presence in the amounts potentially producing consequences if present in closed spaces. That is conditioned by the phosphogypsum quantity, as well as by the area of space partitioned.

  11. Thermochromic complex compounds in phase change materials. Possible application in an agricultural greenhouse

    The possibility to combine two physico-chemical phenomena is studied in this work in order to attain simultaneous control of temperature and light intensity in a greenhouse: (a) isothermal heat storage in phase change materials and (b) thermochromic behavior of complex compounds dissolved in the phase change materials. Two binary mixtures melting near the ambient temperature were studied: (a) 0.925 Ca(NO{sub 3}){sub 2}{center_dot}4.06 H{sub 2}0+0.075 CaCl{sub 2}{center_dot}6.11 H{sub 2}O melting at 35.6C and (b) 0.9 CH{sub 3}CONH{sub 2}+0.1 Ca(NO{sub 3}){sub 2}{center_dot}4 H{sub 2}O, melting at 27.7C. The melting temperature, the enthalpy of fusion and the heat capacity of both mixtures were determined from DSC measurements. Both mixtures showed to be suitable solvents for the formation of consecutive cobalt(II) chloride complexes. The compositions of the complex compounds were adjusted in each mixture so that the absorption spectra in visible spectral range exhibited low absorbance at the melting temperature and a pronounced increase of the absorbance and/or change of color with the increase of temperature in the range relevant for passive solar energy receivers. The combined latent heat storage and the outstanding reversible change of the optical properties of the dissolved complex compounds with temperature is proposed to be applied in solar heated agricultural greenhouses in areas with fluctuating climate conditions. The increase of absorbance with temperature acts as an auto-regulated shading protection from overheating

  12. ZnO - Wide Bandgap Semiconductor and Possibilities of Its Application in Optical Waveguide Structures

    Struk Przemysław

    2014-08-01

    Full Text Available The paper presents the results of investigations concerning the application of zinc oxide - a wideband gap semiconductor in optical planar waveguide structures. ZnO is a promising semiconducting material thanks to its attractive optical properties. The investigations were focused on the determination of the technology of depositions and the annealing of ZnO layers concerning their optical properties. Special attention was paid to the determination of characteristics of the refractive index of ZnO layers and their coefficients of spectral transmission within the UV-VIS-NIR range. Besides that, also the mode characteristics and the attenuation coefficients of light in the obtained waveguide structures have been investigated. In the case of planar waveguides, in which the ZnO layers have not been annealed after their deposition, the values of the attenuation coefficient of light modes amount to a~ 30 dB/cm. The ZnO layers deposited on the heated substrate and annealed by rapid thermal annealing in an N2 and O2 atmosphere, are characterized by much lower values of the attenuation coefficients: a~ 3 dB/cm (TE0 and TM0 modes. The ZnO optical waveguides obtained according to our technology are characterized by the lowest values of the attenuation coefficients a encountered in world literature concerning the problem of optical waveguides based on ZnO. Studies have shown that ZnO layers elaborated by us can be used in integrated optic systems, waveguides, optical modulators and light sources.

    2006-01-01

    Full Text Available The main approach to curbing mastitis is to prevent the entry of microorganisms from the outer environment into the mammary gland, which is achieved by the use of papilla disinfection following every time of milking. The objective of this work was to examine the antimicrobial activity of the disinfectant dodicin hydrochloride, in fact the preparation that contains this disinfectant (DESU® M, against bacteria, the most frequent causes of mastitis in cows. The efficacy of modified DESU® Mwas examined under laboratory conditions using the quantitative test against the following microorganisms: Escherichia coli, Staphylococcus aureus, Streptococcus agalactiae and Streptococcus uberis, under the conditions in the field. The udders of an experimental group of 20 cows of the Holstein-Friesian breed were immersed in a solution of the modified preparation DESU ® M following every time of milking over a period of three months. In the second group of 10 cows of the Holstein-Friesian breed, marked as the control group, no disinfection was applied following the milkings. The preparation DESU® Mexhibited satisfactory antimicrobial efficacy against the most frequent causes (Escherichia coli, Staphylococcus aureus, Streptococcus agalactiae and Streptococcus uberis of mastitis in cows under laboratory conditions. With the application of the preparation DESU® M, following every time of milking over a period of three months, the number of somatic cells was reduced by almost one half in comparison with their number at the start of the experiment. No residue of the modified preparation DESU ® M were found in any sample of milk from the experimental group of cows.

  14. Possible applications of instruments of measurement of the customer value in the operations of logistics companies

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available Background: The growing popularity in recent years of marketing concepts of putting clients in the centre of the interest of companies as well as easy access to data related to customers' behaviors led to the increase of the importance of such concepts as the profitability and the value of the customer. But the customer value in not an unequivocal concept. It can be defined and measured individually depending on the needs of a company, an industry character, objectives or a time horizon. Methods: The following, most often used, methods for measuring customer value were selected, described and analyzed from the point of view of their usefulness: different types of the portfolio method (e.g. two-steps and three-steps one, nine-field matrix, etc, multidimensional analysis of customers, analysis of the rentability of customers, model PCV, ABC method, RFM method and CLV indicator. Results: The advantages and disadvantages of each of analyzed methods were presented and evaluated. The possible use of each of the methods was presented and discussed. In the sector of logistics companies, the measurement of the customer value can be an effective tool in managing the customer relationships and in increasing their profitability. Since there is no only one universal way of measuring the customer value, which is appropriate for every selected industry branch, the choice of a particular method depends on many factors, such as a business profile or number of clients served by a company. Conclusions: The aim of the identification of key customers is to facilitate the optimal allocation of resources of the company. Not all customers are equally important for the company, and the company is not able and should not try to acquire and satisfy needs of each customer. It should be remembered, that the evaluation of the customer value in logistics companies should not be restricted to only one of discussed methods. The analysis presented in this paper indicates, that

  15. Prospects for an x-ray FEL light source and some possible scientific applications

    International Nuclear Information System (INIS)

    Free electron lasers are now being designed which will operate at wavelengths down to about 1 Aa. Due to the physics of the high-gain, single pass FEL process that these sources will exploit, the radiation produced will have unique properties. In particular: The FEL peak intensity and peak brightness will be many orders of magnitude higher than can be produced by any other source. The pulse length will be less than 1 picosecond, orders of magnitude shorter than can be achieved with any other bright source such as a synchrotron. The FEL radiation will have full transverse coherence and a degeneracy parameter (photons/coherence volume) equal to 109 or more. No other source can produce hard x-radiation with a degeneracy parameter significantly greater than 1. These properties offer the chance to study chemical, biological, and condensed matter dynamical processes with sub-picosecond time resolution and angstrom spatial resolution. The high peak power of the FEL radiation (greater than 1014 W/cm2) could be used to create precisely-controlled chemical and structural modifications inside samples. There is also the possibility that nonlinear x-ray interactions could be used to give increased resolution for spectroscopic studies, to greatly expand the parameter space for atomic physics studies, and to permit new fundamental tests of quantum mechanics. The exploration of these new x-ray techniques will require considerable development, not only in technical areas such as optics and detectors, but also in understanding the basic physics of the interaction of very intense x-radiation with matter. A large collaboration of US institutions is now conducting preliminary research and development in these areas, with the intention of creating an FEL operating at 1.5 Aa in about the year 2006. Germany also has a strong short-wavelength FEL research program, with a soft x-ray FEL under construction and a proposal for a future large facility which would produce a variety of hard and

  16. Handheld multi-channel LAPS device as a transducer platform for possible biological and chemical multi-sensor applications

    International Nuclear Information System (INIS)

    The light-addressable potentiometric sensor is a promising technology platform for multi-sensor applications and lab-on-chip devices. However, many prior LAPS developments suffer from their lack in terms of non-portability, insufficient robustness, complicate handling, etc. Hence, portable and robust LAPS-based measurement devices have been investigated by the authors recently. In this work, a 'chip card'-based light-addressable potentiometric sensor system is presented. The utilisation of ordinary 'chip cards' allows an easy handling of different sensor chips for a wide range of possible applications. The integration of the electronic and the mechanical set-up into a single reader unit results in a compact design with the benefits of portability and low required space. In addition, the presented work includes a new multi-frequency measurement procedure, based on an FFT algorithm, which enables the simultaneous real-time measurement of up to 16 sensor spots. The comparison between the former batch-LAPS and the new FFT-based LAPS set-up will be presented. The immobilisation of biological cells (CHO: Chinese hamster ovary) demonstrates the possibility to record their metabolic activity with 16 measurement spots on the same chip. Furthermore, a Cd2+-selective chalcogenide-glass layer together with a pH-sensitive Ta2O5 layer validates the use of the LAPS for chemical multi-sensor applications

    Directory of Open Access Journals (Sweden)

    GAUTO, Marcelo Antunes

    2010-01-01

    Full Text Available Glycerin is a by-product obtained during the biodiesel manufacture, through the transesterification reaction of vegetal oils. The prevision of excedent glycerine in the next few years, due to the increasing of the biodiesel production in Brazil, has been generating a discussion about new applications to this by-product. This article presents a theoretical study about the possible synthesis of a new flocculant agent, from semi-refined glycerine and p-nitrobenzoic acid to produce a quaternary ammonium salt, to be used in water treatment. The reactions which would occur during the synthesis of the flocculant agent and the necessary tests to the product validation are presented.

  18. Radiation applications in art and archaeometry. X-ray fluorescence applications to archaeometry. Possibility of obtaining non-destructive quantitative analyses

    Milazzo, Mario

    2004-01-01

    The possibility of obtaining quantitative XRF analysis in archaeometric applications is considered in the following cases: Examinations of metallic objects with irregular surface: coins, for instance. Metallic objects with a natural or artificial patina on the surface. Glass or ceramic samples for which the problems for quantitative analysis rise from the non-detectability of matrix low Z elements. The fundamental parameter method for quantitative XRF analysis is based on a numerical procedure involving he relative values of XRF lines intensity. As a consequence it can be applied also to the experimental XRF spectra obtained for metallic objects if the correction for the irregular shape consists only in introducing a constant factor which does not affect the XRF intensity relative value. This is in fact possible in non-very-restrictive conditions for the experimental set up. The finenesses of coins with a superficial patina can be evaluated by resorting to the measurements of Rayleigh to Compton scattering intensity ratio at an incident energy higher than the one of characteristic X-ray. For glasses and ceramics the measurements of the Compton scattered intensity of the exciting radiation and the use of a proper scaling law make possible to evaluate the matrix absorption coefficients for all characteristic X-ray line energies.

  20. EPR Study of Radiation-Induced Radicals in Gaba: A Possible Tissue Equivalent Dosimeter For Medical Applications

    International Nuclear Information System (INIS)

    Evaluation of radiation doses delivered by patients during the therapeutic sessions of cancer is of much importance, especially in cases of recently implemented techniques like IMRT and/or radiosurgery. EPR is one of radiation dosimetric techniques which characterized by its non-destructive evaluation of radiation doses delivered to the dosimeters. In the current study, gamma aminobutyric acid (GABA) is suggested as a possible radiation dosimeter for medical applications due to its bio-nature and its expected tissue-equivalency. EPR spectrum of GABA was recorded for the first time and some spectroscopic characteristics were studied including the effect of microwave power on the peak-to-peak signal intensity and the effect of modulation amplitude. The determined linear range in microwave dependence was found to be 1 mW and the calculated effective atomic number was found to be 6.87. The time dependence was studied over 18 days after irradiation and the decay over such period in signal amplitude was about 10 %.

  1. Synthesis and characterization of thin films of Pd/TiO2 with possible applications in photo catalysis

    International Nuclear Information System (INIS)

    In this paper the synthesis and study of thin films of titanium oxide is reported, as well as those that were surface modified with palladium nanoparticles Pd/TiO2. First, the TiO2 films are grown on substrates of soda-lime glass using chemical sol-gel route and the repeated immersion procedure. The salt precursor titanium oxy-acetylacetonate to 0.2 M, in the solvent 2-methoxyethanol and monoethanolamine was used as stabilizer. The number of used immersions gave an average thickness estimate for these films of 172.8 nm. Second, the series of Pd/TiO2 films surface modified were obtained from a solution of palladium nitrate dehydrate at low concentration, with the same procedure. The films grown TiO2 and those surface-modified films were characterized in its structure by X-ray diffraction, morphology by scanning electron microscopy, the topography with atomic force microscopy, optical properties by UV-Vis, among others. Photoluminescence properties and/or possible applications in photo catalysis are reported in this paper. (Author)

  2. Risk assessment of atmospheric contamination due to combustion of fossil-fuels in Japan and possible application of fuzzy set

    International Nuclear Information System (INIS)

    For risk assessment of atmospheric contamination due to fossil-fuel combustion in Japan, epidemiological studies have been conducted since 1961. Health effects of sulfur dioxide in industrial areas of Japan where fossil-fuel power stations are located have been investigated. The dose-response relationship between prevalence rates of chronic bronchitis and sulphur dioxide was established. Various efforts have been made to reduce the concentrations of sulfur dioxide in the atmosphere. However, the average concentration of NO2 tended to increase gradually. It was therefore considered important to study the health effects of nitrogen dioxide. In different areas of Japan with varying atmospheric concentrations of nitrogen dioxide, an extensive epidemiological survey was conducted with over 10,000 school-children. The results of the survey indicate that the prevalence rates of asthma and wheezing were higher with the higher degree of air pollution, and that the indoor pollution is important. It is also attempted to compare hazard indices of the air-borne wastes from fossil-fuel power plants and those from nuclear power plants. The conventional pollutants seem to be much more important as compared with the radioactive releases under normal conditions of operation. The survey of stochastic effects with very small chances of occurrence was not attempted because of the great uncertainties and difficulties in identifying a small signal within a large noise. The possible application of the theory of Fuzzy Set for risk analysis is suggested

  3. Quasi-parallel electron beams and their possible application in inferring the auroral arc's root in the magnetosphere

    2013-06-01

    Full Text Available In this study we investigate the upgoing electron beams at the topside ionosphere and their counterpart feature, the bidirectional quasi-parallel electron beams (QPEB in the equatorial magnetosphere, with highlight on their potential application in estimating the location of the arc's root (AR in the magnetotail central plasma sheet (CPS. We infer from FAST data that the upgoing electron beam is often found in the equatorward vicinity of the inverted-V arc. On the premise of such a scenario, we propose a method to estimate the location of the AR from available magnetospheric measurements by assuming that the tailward boundary of the QPEB demarcates the earthward boundary of the AR. We report two events with THEMIS observations of QPEBs in the magnetotail CPS, and demonstrate how to use the QPEB features, together with the magnetic signatures of the current circuit constituted by the QPEB and arc, to estimate the earthward boundary of the AR. We find that the estimated earthward boundary of AR is situated at the periphery of a quasi-dipolar magnetosphere characterized by a strong Bz gradient. This finding is consistent with previously existing proposals on the possible AR location in the tail (e.g., Lui and Burrows, 1978; Sergeev et al., 2012.

  4. A possible cosmological application of some thermodynamic properties of the black body radiation in $n-$dimensional Euclidean spaces

    2015-01-01

    In this work we present the generalization of some thermodynamic properties of the black body radiation (BBR) towards an $n-$dimensional Euclidean space. For this case the Planck function and the Stefan-Boltzmann law have already been given by Landsberg and de Vos and some adjustments by Menon and Agrawal. However, since then no much more has been done on this subject and we believe there are some relevant aspects yet to explore. In addition to the results previously found we calculate the thermodynamic potentials, the efficiency of the Carnot engine, the law for adiabatic processes and the heat capacity at constant volume. There is a region at which an interesting behavior of the thermodynamic potentials arise, maxima and minima appear for the $n-d$ BBR system at very high temperatures and low dimensionality, suggesting a possible application to cosmology. Finally we propose that an optimality criterion in a thermodynamic framework could have to do with the $3-d$ nature of the universe.

    2013-01-01

    The existing research on sense of humour in schizophrenia is focused on two main areas, mainly, assessment of patients' abilities to understand and appreciate humour and denoting the possibilities of its application in therapeutic programs concentrating on the improvement of patients' functionality and preventing illness relapses. The vast majority of the conclusions from the above mentioned research corroborate the opinion on the usefulness of developing and reinforcing sense of humour in schizophrenia, emphasizing its beneficial effect on the patients' quality of life, above all, in terms of reducing aggression, anxiety and depression as well as improving general life satisfaction and social functioning. At the same time numerous research indicate low reception of humour in schizophrenia which can negatively influence its effective usage in therapeutic interventions. Further constraint with regard to the therapy can constitute an intensified fear for being laughed at, which has been confirmed in numerous empirical reports. Therefore, it seems that addressing humorous therapeutic interventions to the above mentioned group of patients requires especially careful planning taking into consideration its cognitive and affective limitations in the perception of humour and intensified fear for being laughed at.

    In arid regions like the Dead Sea (DS) water supply mostly relies on restricted groundwater resources, which are in many cases defined by large inaccessible areas with scarce in-situ data. However, particularly in these regions it is essential to obtain detailed information of this precious resource in order to develop a sustainable water management - one of the main aims of the BMBF-funded multilateral SUMAR (Sustainable Management of Arid and Semiarid Regions) project. The usage of remote sensing offers different indicators and directly sensed patterns from different platforms providing important data where practical alternatives or simply spatial data are not available (Becker, 2006). One application possibility regards the identification of lineaments which are simple or composite linear features of a surface and which have been proven to reflect general groundwater flow-paths (Sander, 1997). In a previous study we derived lineaments using a freely available digital elevation model (30 m spatial resolution) and developed a semi-automatic approach composed of low pass and 2nd order Laplace linear filtering and a subsequent object based classification. Based on these lineaments we could identify general groundwater flow-paths with striking directional trends towards known spring areas along the DS (Mallast et al., 2011). With the knowledge of both, location of spring areas and a given temperature contrast between ground- and DS water, we derived by using thermal remote sensing from satellite and airborne platforms a second application possibility. Satellite based thermal remote sensing with Landsat ETM+ images allowed us to identify groundwater discharge pattern, which highly correlate in location with the previously derived flow-paths, but also enabled us to relatively quantify also seasonal varying groundwater discharge over a time period of 12 years (2000-2011). The drawback remains in the spatial resolution of 30 m (resampled from United States Geological

    The possibility of attaining an superhard state in multilayer vacuum-arc ZrN/CrN coatings with a layer thickness of about 20 nm has been established. It has been shown that the application of a constant negative potential for structural engineering during deposition leads to the formation of solid solutions due to mixing of interfaces. The hardness of these systems exceeds 30 GPa. The application of a pulsed high-voltage bias potential at which the ordering of atoms stimulated by elevated mobility is observed makes it possible to suppress the mixing of the interfaces and to attain elevated hardness (up to 42 GPa) for nanometer layer thicknesses.

    International Nuclear Information System (INIS)

    With the help of the new hybrid technique SPECT/ CT it is possible, using the only investigation, to acquire a combine image of the investigated organ, visualizing its function and structure. Combining the possibilities of the new multimodality method, which combines the possibilities of the Single Photon Emission Computer Tomography - SPECT and Computer Tomography - CT, it is possible to precisely localize the pathologically changed organs function. With the further combination of the tomographic gamma camera with diagnostic CT, a detailed morphological evaluation of the finding was possible. The main clinical application of the new hybrid diagnostic is in the fields of cardiology, oncology, orthopedics with more and more extension of those, not connected with oncology, such as - thyroid, parathyroid, brain (especially localization of the epileptic foci), visualization of local infection and recently for the purposes of the radiotherapy planning. According to the literature data, around 35% of SPECT-investigations have to be combined with CT in order to increase the specificity of the diagnosis, which changes the interpretation of the result in 56% of the cases. After installation of the SPECT/CT camera in the University hospital 'Alexandrovska' in January 2009, the following changes have been done: the number of the investigated patients have increased, including number of heart, thyroid (especially scintigraphy with 131I), bones and parathyroid glands. As a result of the application of the hybrid technique, a shortage of the investigated time was realized and a decrease prize in comparison with the individual application of the investigations. Summarizing the literature data and the preliminary impression of the first multimodality scanner in our country in the University hospital 'Alexandrovska' it could be said, that there is continuously increasing information for the new clinical applications of SPECT/CT.

    Before testing the performance characteristics of andisols for retention of anions in the near-field environment of Low Level Wastes (LLW) disposal facilities it is necessary to locate one or more sufficiently extensive bodies of natural soil with the highest possible natural anion exchange capacity. For this purpose we developed a rugged, portable semiquantitative field test for anion exchange capacity based on short-term sorption of iodide by soil samples. We validated the iodide sorption field test against a well established quantitative laboratory test based on anion exchange of chloride and nitrate, then carried out an initial survey of volcanic terrain in northern California using the field test.

    Seaweeds are a reserve of natural dyes (chlorophylls a, b and c), characterized by low cost and easy supply, without potential environmental load in terms of land subtraction, and also complying with the requirements of an efficient waste management policy. In particular, the brown seaweed Undaria pinnatifida is a species largely present in the Venice Lagoon area, and for it a removal strategy is actually mandatory. In this paper, we set-up an eco-protocol for the best extraction and preparation procedures of the pigment, with the aim of finding an easy and affordable method for chlorophyll c extraction, exploring at the same time the possibility of using these algae within local sustainable management integrated strategies, among which the possible use of chlorophylls as a dye source in dye sensitized solar cells (DSSCs) is investigated. Experimental results suggest that the developed protocols are useful to optimize the chlorophyll c extraction, as shown by optical absorption spectroscopy measurements. The DSSCs built with the chlorophyll extracted by the proposed eco-protocol exhibit solar energy conversion efficiencies are similar to those obtained following extraction protocols with larger environmental impacts.

    Previous concepts of immune-privileged sites obscured the role of peripheral immune cells in neurological disorders and excluded the consideration of the potential benefits of immunotherapy. Recently, however, numerous studies have demonstrated that the blood-brain barrier in the central nervous system is an educational barrier rather than an absolute barrier to peripheral immune cells. Emerging knowledge of immune-privileged sites suggests that peripheral immune cells can infiltrate these sites via educative gates and that crosstalk can occur between infiltrating immune cells and the central nervous system parenchyma. This concept can be expanded to the testis, which has long been considered an immune-privileged site, and to neurogenic bladder dysfunction. Thus, we propose that the relationship between peripheral immune cells, the brain, and the urologic system should be considered as an additional possible mechanism in urologic diseases, and that immunotherapy might be an alternative therapeutic strategy in treating neurogenic bladder dysfunction.

  12. Study about the application possibilities from the heterogeneous photo-catalysis to the phenols removal processes in watery medium

    International Nuclear Information System (INIS)

    Phenols are recalcitrant and quite-toxic organic compounds, which are generally in wastewaters from some industries, such as petrochemical, paper mills, chemical industries of production of pesticides and herbicides, among others. Conventionally these compounds are treated with some treatment, such as electrochemistry, biodegradation or incineration, in which ones it is not achieved an optimal removal of phenols. Due to this becomes necessary the study of more efficient techniques. Heterogeneous photo-catalysis belongs one to them, which one is based on a catalytic reaction that involves the absorption of light on a semiconductor, with the purpose of degrading the organic pollutants to dioxide of carbon, water an mineral acids these ones innocuous or e environment. At the moment, studies look for to optimize the values for the different parameters that affect the photo-catalytic process. These are: pH, temperature, radiation intensity, reactor design, nature and concentration of the pollutant, preservatives, and kinetics of the reaction. This last one plays a very important role in the real application of the process. The tendency of the photo-catalysis is focused to the development of useful prototypes in the industry, mainly in decontamination treatments of air, water, or soils, and in self-cleaning surface application

    Full Text Available For decades, the standard metallic materials for hip implants, besides the 316LVM stainless steel, were titanium- and cobalt/chromium-based alloys. Although bioinert, due to their corrosion resistance, they are not biocompatible. Contemporary surgical implants are not made just of bioinert metal anymore, but with deposited bioactive hydroxyapatite (HAp coating. Hydroxyapatite is chemically identical with the mineral constituent of bones and teeth, what besides its biocompatibility provides bioactivity as well. The HAp limitations are, however, weak tensile strength and low fatigue resistance for long term loadings, if used alone. This is the reason for HAp to be deposited onto the surgical implant, and to enable its bioactivity, what means intergrowth with bones, and therefore the long-lasting and mechanical stable non-cemented prosthesis. This is important predominantly because the need for such prostheses for younger population, and a better life quality. There are several contemporary techniques that have been used for deposition of these coatings onto the metal implant. The possibilities of atmospheric plasma-spraying for obtaining the stable HAp coatings on the 316LVM stainless steel, ordinary used as a standard material for hip implants production are presented in this paper. The coatings of a commercially available hydroxyapatite powder were plasma-sprayed onto the specimens of medical grade 316LVM stainless steel under various operating conditions. The optical microscopy was used for microstructure and porosity characterization, while coating morphology and Ca/P ratio were analyzed using SEM equipped with EDX. Coating microstructure varied from a porous to a glassy structure, depending on operating conditions applied and coating thickness. Coating porosity was determined to be at the lower required limit requested for the bone-coating intergrowth possibility, but nevertheless adhesion measurements showed good results. The Ca/P ratio was

    International Nuclear Information System (INIS)

    The work given in this thesis aimed at Fabrication of high quality nano phosphor particles for getting high sensitive thermoluminescence material to use as ionizing radiation dosimeter. Ca Sr S nano phosphor has been prepared by solid state diffusion reaction method. The prepared nano phosphor was then activated with proper addition of some rare earth elements (dysprosium and gadolinium) for the sake of improving its TL sensitivity. The doped Ca Sr S nano phosphor was then treated by different courses of heat annealing for dual sake and regeneration. High temperature and high gamma dose sensitization are also used to increase sensitivity of Ca Sr S doped. By this means the TL-intensity of treated samples proved about 24 times observed enhancement. The prepared Ca Sr S: Dy nano phosphor is very reliable as pure gamma dosimeter for various applications such as personal, environmental and clinical dosimetry.

    2011-08-01

    Full Text Available Abstract Background Computed Tomography (CT is a technology that obtains the tomogram of the observed objects. In real-world applications, especially the biomedical applications, lower radiation dose have been constantly pursued. To shorten scanning time and reduce radiation dose, one can decrease X-ray exposure time at each projection view or decrease the number of projections. Until quite recently, the traditional filtered back projection (FBP method has been commonly exploited in CT image reconstruction. Applying the FBP method requires using a large amount of projection data. Especially when the exposure speed is limited by the mechanical characteristic of the imaging facilities, using FBP method may prolong scanning time and cumulate with a high dose of radiation consequently damaging the biological specimens. Methods In this paper, we present a compressed sensing-based (CS-based iterative algorithm for CT reconstruction. The algorithm minimizes the l1-norm of the sparse image as the constraint factor for the iteration procedure. With this method, we can reconstruct images from substantially reduced projection data and reduce the impact of artifacts introduced into the CT reconstructed image by insufficient projection information. Results To validate and evaluate the performance of this CS-base iterative algorithm, we carried out quantitative evaluation studies in imaging of both software Shepp-Logan phantom and real polystyrene sample. The former is completely absorption based and the later is imaged in phase contrast. The results show that the CS-based iterative algorithm can yield images with quality comparable to that obtained with existing FBP and traditional algebraic reconstruction technique (ART algorithms. Discussion Compared with the common reconstruction from 180 projection images, this algorithm completes CT reconstruction from only 60 projection images, cuts the scan time, and maintains the acceptable quality of the

This research aims to integrate bagging and proportion case-basing with CBR to generate a method of proportion bagging CBR for EOPFOF. Diverse multiple case bases are first produced by multiple case-basing, in which a volume parameter is introduced to control the size of each case base. Then, the classic case retrieval algorithm is implemented to generate diverse member CBR predictors. Majority voting, the most frequently used mechanism in ensemble computing, is finally used to aggregate outputs of member CBR predictors in order to produce final prediction of the CBR ensemble. In an empirical experiment, we statistically validated the results of the CBR ensemble from multiple case bases by comparing them with those of multivariate discriminant analysis, logistic regression, classic CBR, the best member CBR predictor and bagging CBR ensemble. The results from Chinese EOPFOF prior to 3 years indicate that the new CBR ensemble, which significantly improved CBR's predictive ability, outperformed all the comparative methods.

    Full Text Available The Czech national law regulating accounting is not harmonized with International Financial Reporting Standards (IFRS. Because of this, all financial statements compiled according to Czech regulations are not comparable with IFRS statements. International users of accounting information, e.g. potential investors, therefore have problems to find valid information. This article analyzes the evaluation, accounting recording, and reporting of biological assets and agricultural produce in both accounting systems. It illustrates the principal differences, and explains their impact on financial statements information. Based on a case study, the paper recommends how to implement IFRS principles to the accounting system in Czech agriculture enterprises. The authors recommend using income statements with expenses by function, which is not commonly used by Czech entities. The research findings indicate possible changes in the Czech accounting and tax laws, which may lead to a “more true and fair view” of provided accounting information. The proposals should cause that accounting information provided by financial statements compiled according to Czech law would be identical with accounting information in compliance with IFRS principals. A questionnaire survey revealed scepticism of economists agricultural companies to use fair value as the measurement basis for biological assets and agricultural produce.

  1. Molecular evolution of the exon 2 of CHS genes and the possibility of its application to plant phylogenetic analysis

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    The exon 2 of chalcone synthase (CHS) gene is relatively conserved during evolution.In this study,three exon 2 fragments from two species in gymnosperm (Cycas panzhihuaensis,Ginkgo biloba) and seven from four species in angiosperm (Magnolia denudata,Salix babylonica,Nymphaea tetragona,Camellia japonica) have been amplified by PCR from genomic DNA and sequenced.Together with other 73 sequences of CHS collected from EMBL database and literature,these sequences,which embrace 19 families of gymnosperm and angiosperm,have been analyzed for their phylogenetic relations by parsimony method.The result indicated that sequences from the same systematic family usually grouped together except those from Theaceae,Magnoliaceae and Nymphaeaceae.The relative rate test revealed the rate heterogeneity of CHS genes among the families.For the nucleotide substitution the sequences from Asteraceae and Solanaceae evolve faster than those from the other families analyzed while the sequences from Poaceae,Asteraceae and Solanaceae evolve faster for the nonsynonymous substitution.These results suggest that the duplication and extinction events of CHS genes are different among systematic families,therefore it seems impractical to look for orthologous sequences from CHS genes to study plant phylogeny at the family level and/or above.However,it is possible to do so below the family level.

  2. Survey of some natural decay-series isotopes in the Wairakei geothermal area and possible residence-time applications

    International Nuclear Information System (INIS)

    Concentrations of selected isotopes in the uranium decay series were determined for samples collected from the Wairakei, Broadlands/Ohaaki and Waiotapu areas. /sup 226/Ra concentrations were found to be low (0.05-0.22 dpm/l), similar to values reported in neutral hot springs at Tatun geothermal area, Taiwan, but lower than other geothermal systems (Yellowstone, USA, and Latera, Central Italy) (up to 25 dpm/l). The potential of /sup 226/Ra//sup 228/Ra ratios for indicating water residence times could not be explored because /sup 228/Ra data was not available. /sup 222/Rn concentrations are higher and related to steam fractions and CO/sub 2/ concentrations. The short half-life (3.8 days) makes /sup 222/Rn suitable for estimating residence times of radon in steam, and therefore the distance of travel of steam from its source (e.g., wells WK9 and 52). /sup 210/Pb and /sup 210/Po concentrations were very low and less than detection limits in many of the Wairakei waters; no residence time applications are apparent for these isotopes.

  3. Dynamic perception: Some theorems about the possibility of parallel pattern recognition with an application to high energy physics

    International Nuclear Information System (INIS)

    In the context of M. Minsky's and S. Papert's theorems on the impossibility of evaluating simple linear predicates by parallel architectures the authors want to show how these limitations can be avoided by introducing a generalized input-dependent preprocessing technique that does not suppose any a-priori knowledge of input like in classical input filtering procedures. This technique can be formalized in a very general way and can be also deduced by metamathematical arguments. A further development of the same technique can be applied at level of learning procedure to introduce in such a way the complete notion of open-quotes dynamic perceptronclose quotes. From the experimental standpoint, they show two applications of the open-quotes dynamic perceptronclose quotes in particle track recognition in high-energy accelerators. Firstly, they show the amazing improvement of performances that can be obtained in a perceptron architecture with classical learning by adding their open-quotes dynamicclose quotes pre-processing technique, already introduced last year in another paper presented at this Conference. Secondly, they show the results of this technique extended also at the level of learning procedure always applied to the problem of particle track recognition. This work is a part of open-quotes Feniceclose quotes international collaboration supported by INFN (National Institute for Nuclear Physics) devoted to the study of the time-like electromagnetic form factor of neutrons obtained by electron-positron high energy collisions in ADONE (Frascati, Rome) storage ring

  4. Observations of Earthquake-Generated T-Waves in the South China Sea: Possible Applications for Regional Seismic Monitoring

    Full Text Available We present a detailed study of T-waves originating from earthquakes in the South China Sea region, near the Indochina Peninsula and Luzon islands which were recorded by a broadband seismic station at Nansha Island. Most of these T-waves appear to have been the source originating from earthquakes with epicentral distances greater than 600 km from this station. The T-waves in this region were identified via their apparent stable measured velocities of about 1.45 km s-1, and represent the first reported T-waves and the first T-waves observed from an island station in the South China Sea. However, during the period of analysis (November 2004 to December 2005 additional earthquakes also occurred beyond the South China Sea region, but in these instances, any associated T-waves were not picked up by the station at Nansha Island. An analysis of T-wave travel times reveals the possible locations of the P-wave to T-wave transitions at the ocean to crust interface were presumably situated near the earthquake source side. Our results indicate that the Sound Fixing and Ranging (SOFAR channel is well developed in the South China Sea region. Ultimately, developing a solid understanding of the effective transmission of T-waves through the ocean may provide new opportunities for detecting and locating small earthquakes which would be useful for both seismic monitoring and in helping to predict and reduce the damaging effects of earthquakes and tsunamis in the South China Sea region.

  5. Possible application of X-ray optical elements for reducing the spectral bandwidth of an X-ray SASE FEL

    A new design for a single pass X-ray Self-Amplified Spontaneous Emission (SASE) FEL is proposed. The scheme consists of two undulators and an X-ray monochromator located between them. The first stage of the FEL amplifier operates in the SASE linear regime. After the exit of the first undulator the electron bunch is guided through a non-isochronous bypass and the X-ray beam enters the monochromator. The main function of the bypass is to suppress the modulation of the electron beam induced in the first undulator. This is possible because of the finite value of the natural energy spread in the beam. At the entrance to the second undulator the radiation power from the monochromator dominates significantly over the shot noise and the residual electron bunching. As a result the second stage of the FEL amplifier operates in the steady-state regime when the input signal bandwidth is small with respect to that of the FEL amplifier. Integral losses of the radiation power in the monochromator are relatively small because grazing incidence optics can be used. The proposed scheme is illustrated for the example of the 6 nm option SASE FEL at the TESLA Test Facility under construction at DESY. As shown in this paper the spectral bandwidth of such a two-stage SASE FEL (Δλ/λ⋍ 5 × 10-5) is close to the limit defined by the finite duration of the radiation pulse. The average brilliance is equal to 7 × 1024photons/(s × mrad2 × mm2 × 0.1% bandw.) which is by two orders of magnitude higher than the value which could be reached by the conventional SASE FEL. The monochromatization of the radiation is performed at a low level of radiation power (about 500 times less than the saturation level) which allows one to use conventional X-ray optical elements (grazing incidence grating and mirrors) for the monochromator design.

    Due to our current way of life and the environmental influences we are exposed in the industrial nations, cancer diseases turn out to be a more and more serious threat to our civilization. The ongoing research during the last decades leads to a better insight in cancer diseases and enables an earlier recognition of developing carcinoma. The detection of pathological tissue changes at an early stage increases the patients' chances of cure. Magnetic resonance tomography (MRT) and computed tomography (CT) as well as radiopharmaceutically assisted imaging techniques, like positron emission tomography (PET) and scintigraphy are an indispensable clinical tool in the oncological early diagnosis. By the development of multimodality imaging agents that combine the benefits of several imaging techniques, the early recognition of tumors can be more efficient and in consequence a matching therapy can be applied. This thesis deals with the synthesis of novel bispidine based ligands and their transition metal complexes as potential mono- and bimodal imaging agents for a {sup 64}Cu-assisted radiopharmaceutical application in positron emission tomography (PET) and optical imaging (OI). The synthesized ligands L and L{sup OH} are offering the opportunity to build up a ruthenium(II) polypyridine complex by one of the ligand's donor sets, to act as a fluorescence dye for optical imaging (OI), and to coordinate {sup 64}Cu{sup II} by the ligand's vacant cavity for positron emission tomography (PET). The Ru{sup II} complex exhibits two different fluorescence activities with two different lifetimes and only one of the two fluorescences is quenched by subsequent complexation of Cu{sup II}. The calculated Cu{sup II} stability constant of L and L{sup OH} is similar to that of the isomeric ligand N{sub 2}py{sub 2} which has been already evaluated as a {sup 64}Cu-radiotracer. Further transition metal complexes of Fe{sup II}, Fe{sup III} and Mn{sup II} are dealing with

  7. Development of Nano-Particles Within Polymeric Materials Prepared by Gamma Radiation and their Possible Practical Applications

    International Nuclear Information System (INIS)

    Nanoparticles can be used in biomedical applications, where they facilitate laboratory diagnostics, or in medical drug targeting nanoparticles based on a core consisting of iron oxides that can be targeted through external magnets. Polyvinyl alcohol/Polyacrylic acid nanoparticles were prepared using gamma rays. The prepared PVA/AAc nano copolymers were treated with Fe2+/ Fe3+ solution followed by ammonia solution to obtain PVA/AAc-Fe3O4 nanoparticle ferrogel. Characterization of the PVA/AAc-Fe3O4 nanoparticle ferrogel was carried out using XRD, TGA, DSc , TEM and AFM. The use of magnetic field sensitive nano-ferrogels as a drug carrier was investigated. It was found that the release of drug in absence of the effect of magnetic field is mostly slow than that under the influence of magnetic field. On the other hand, development of nanoparticles within radiation grafted polymeric surfaces using electroless plating technique was investigated. Surface modification of polypropylene films (PP) was carried out via radiation induced graft copolymerization of 4-vinyl pyridine (4VP) and acrylamide (AAm) to enhance the adhesion ability of the PP surface for electroless deposition of copper. The produced grafted films were characterized by studying their FTIR and thermal stability. The prepared grafted films were copper-plated by electroless deposition using the Pd as a catalyst to initiate the redox reaction. The influences of catalytic activation method parameters on the plating rate have been studied. The electrical characteristics of the copper plated films in comparison with grafted films were studied. The results showed the high adhesion of the deposited copper film to the grafted PP film as well as high electrical conductivity. (author)

    Direct measurement of lung volume, i.e. functional residual capacity (FRC) has been recommended for monitoring during mechanical ventilation. Mostly due to technical reasons, FRC measurements have not become a routine monitoring tool, but promising techniques have been presented. We performed a literature search of studies with the key words 'functional residual capacity' or 'end expiratory lung volume' and summarize the physiology and patho-physiology of FRC measurements in ventilated patients, describe the existing techniques for bedside measurement, and provide an overview of the clinical questions that can be addressed using an FRC assessment. The wash-in or wash-out of a tracer gas in a multiple breath maneuver seems to be best applicable at bedside, and promising techniques for nitrogen or oxygen wash-in/wash-out with reasonable accuracy and repeatability have been presented. Studies in ventilated patients demonstrate that FRC can easily be measured at bedside during various clinical settings, including positive end-expiratory pressure optimization, endotracheal suctioning, prone position, and the weaning from mechanical ventilation. Alveolar derecruitment can easily be monitored and improvements of FRC without changes of the ventilatory setting could indicate alveolar recruitment. FRC seems to be insensitive to over-inflation of already inflated alveoli. Growing evidence suggests that FRC measurements, in combination with other parameters such as arterial oxygenation and respiratory compliance, could provide important information on the pulmonary situation in critically ill patients. Further studies are needed to define the exact role of FRC in monitoring and perhaps guiding mechanical ventilation. PMID:19681779

  9. Applications of the Wei-Lachin multivariate one-sided test for multiple outcomes on possibly different scales.

    Lachin, John M

    2014-01-01

    Many studies aim to assess whether a therapy has a beneficial effect on multiple outcomes simultaneously relative to a control. Often the joint null hypothesis of no difference for the set of outcomes is tested using separate tests with a correction for multiple tests, or using a multivariate T2-like MANOVA or global test. However, a more powerful test in this case is a multivariate one-sided or one-directional test directed at detecting a simultaneous beneficial treatment effect on each outcome, though not necessarily of the same magnitude. The Wei-Lachin test is a simple 1 df test obtained from a simple sum of the component statistics that was originally described in the context of a multivariate rank analysis. Under mild conditions this test provides a maximin efficient test of the null hypothesis of no difference between treatment groups for all outcomes versus the alternative hypothesis that the experimental treatment is better than control for some or all of the component outcomes, and not worse for any. Herein applications are described to a simultaneous test for multiple differences in means, proportions or life-times, and combinations thereof, all on potentially different scales. The evaluation of sample size and power for such analyses is also described. For a test of means of two outcomes with a common unit variance and correlation 0.5, the sample size needed to provide 90% power for two separate one-sided tests at the 0.025 level is 64% greater than that needed for the single Wei-Lachin multivariate one-directional test at the 0.05 level. Thus, a Wei-Lachin test with these operating characteristics is 39% more efficient than two separate tests. Likewise, compared to a T2-like omnibus test on 2 df, the Wei-Lachin test is 32% more efficient. An example is provided in which the Wei-Lachin test of multiple components has superior power to a test of a composite outcome. PMID:25329662

    Strzałka, Dominik; Grabowski, Franciszek

    Tsallis entropy introduced in 1988 is considered to have obtained new possibilities to construct generalized thermodynamical basement for statistical physics expanding classical Boltzmann-Gibbs-Shannon thermodynamics for non-equilibrium states. During the last two decades this q-generalized theory has been successfully applied to a considerable amount of physically interesting complex phenomena. The authors would like to present a short rewiev, the applications and the elementary properties of some operators in deformed q-algebra derived from Tsallis definition of non-extensive entropy based on the definitions of the q-logarithm and the q-exponential. The new definition of the q-root is also introduced.

    The use of recombinases for genomic engineering is no longer a new technology. In fact, this technology has entered its third decade since the initial discovery that recombinases function in heterologous systems (Sauer in Mol Cell Biol 7(6):2087–2096, 1987). The random insertion of a transgene into a plant genome by traditional methods generates unpredictable expression patterns. This feature of transgenesis makes screening for functional lines with predictable expression labor intensive and ...

  13. Remote possibilities

    International Nuclear Information System (INIS)

    The impact that wireless communications has had for gas and oil producers was discussed. Wireless communication, which has been replacing the traditional formats of radio and telephone data networks, has proved to be cheaper, smaller, and faster than creating privately owned communication networks. With highly developed supervisory control and data acquisition systems - combined with cellular or satellite technology - information from drill sites can be online at the corporate headquarters instantaneously. Eighty percent of Canada's land mass is beyond reach of traditional wireline and wireless services. Research into advanced communications, including telecommunication and mobile applications, yielded lucrative results for service providers such as BCTel, SaskTel, Bell Mobility and AGT. The latest data transmission technology is the cellular digital packet data (CDPD) which will operate over existing cellular networks. However, unlike circuit-switched cellular, CDPD technology provides an airlink where data is secure. It will be available to the marketplace over the course of the coming year. Among other advantages, CDPD will allow producers to remotely monitor production information and downtime alarms from wells and compressor stations. It will also provide fleet operators with the means to monitor operating vital signs on rolling stock

  14. Protein and polymer immobilized La0.7Sr0.3MnO3 nanoparticles for possible biomedical applications

    International Nuclear Information System (INIS)

    La0.7Sr0.3MnO3 (LSMO) is a mixed-valent room temperature ferromagnet with properties that are attractive for their applicability in biomedicine. We report, for the first time, immobilization of commonly used biocompatible molecules on LSMO nanoparticles, namely bovine serum albumin and dextran. The former was conjugated to LSMO using 1-ethyl-3-(3-dimethyl aminopropyl)-carbodiimide (CDI) as a coupling agent while the latter was used without any coupler. These bioconjugated nanoparticles exhibit several properties that suggest their applicability in the field of biomedicine, namely (a) no changes in the Curie temperature at ∼360 K after conjugation with biomolecules, (b) rapid attainment of the desired temperature (48 deg. C) at low concentration (e.g. fluidized dextran-coated system at 80 μg ml-1) upon exposure to 20 MHz radio-frequency, (c) extremely low cytotoxicity in skin carcinoma, human fibrosarcoma and neuroblastoma cell lines and (d) high stability of the LSMO system with negligible leaching of ionic manganese into the delivery medium, indicating their safety in possible human applications

    Combustion of solid biofuels, peat and different types of waste in Sweden for the purpose of energy production generates approximately 1.3 million tonnes of residues yearly. These have varying chemical and technical properties, depending on the type of fuel, the combustion process and the type of furnace. From a technical point of view, some of the ashes may be used for civil works. However, the Swedish Environmental Code requires that operators obtain a permit from the local environmental authorities if ashes are utilized for construction purposes. Previous studies on the application and permitting process have indicated that it can be improved, in particular both the information provided by the operators and the decision process. The stakeholders involved in the decision process have expressed that they have limited knowledge on expected environmental impacts from the utilization of ashes in civil works and that existing knowledge not is being fully applied in practice. The aim of this project was to improve the decision support for permit application of ash utilization in constructions. The goals were to - initiate and develop the discussion regarding which information should be used in the decision process - suggest the scope and content of the information to be supplied in the permit application - contribute to improved communication between different stakeholders - identify possibilities of using the knowledge obtained by research for decision support The stakeholders' (operators and environmental authorities) opinions and viewpoint on the assessment and application process were achieved through interviews. The results from the interviews were presented and discussed during a seminar. Both the interviews and the seminar provided information, but at the same time they served to initiate a discussion on permit application procedure and to increase the communication between different stakeholders. The outcomes from these activities (interviews and seminar

    Single hollow fibers were used in specially made cells for fast concentration and dialysis of solutions containing macromolecules. Volumes on the order of 5 ml of diluted protein solutions could be concentrated to 50--100 ..mu..l or less within 7 min with a protein recovery of 60--80%. More than 99% of the molecules with a molecular weight less than 500 could be removed in less than 1 hr. A possible application of the rapid dialysis method for the mechanization of radioimmunoassays is indicated. It was shown that in the radioimmunoassay of steriods the unbound steroids could be removed after incubation with antiserum, within 10 min and without a change in volume.

  17. Preoperative functional magnetic resonance tomography (fMRI) in patients with rolandic brain tumors: indication, investigation strategy, possibilities and limitations of clinical application

    International Nuclear Information System (INIS)

    Preoperative functional magnetic resonance imaging (fMRI) localizes the primary motor and somatosensory cortex in relation to rolandic brain tumors and determines plastic cortical reorganization. Functional landmarks help to assess the indication for surgery and to plan for safer surgical procedures that protect the functional cortex during resection even when morphologic landmarks are no longer identifiable on anatomic images. Despite its successful application, preoperative fMRI has not yet reached the status of an established clinical diagnostic procedure since special stimulation systems, standardized fMRI protocols and medically approved software are still lacking. Following a brief review of the image display of the functional and morphologic anatomy, the different indications for preoperative fMRI in patients with rolandic brain tumors are presented. A robust preoperative protocol enables clinical MR units with magnetic field strengths of 1.0 Tesla or higher to perform reliable fMRI during contralateral hand movements. Optimized investigation strategies and stimulation modalities are proposed for patients with rolandic tumors distant from the cortical hand representation, for patients with preexisting sensorimotor deficits and for patients with poor compliance. Representative cases illustrate the clinical application. Possibilities and limitations of preoperative fMRI are presented and discussed. (orig.)

  18. Enhanced orange-red emission from KSrVO4:Sm3+ nanophosphor for possible application in blue light-emitting diode based white LED

    International Nuclear Information System (INIS)

    In this paper, the combustion synthesis and photoluminescence properties of Sm3+ doped KSrVO4 nanophosphors are reported. The samples were characterized by different techniques such as x-ray powder diffraction, transmission electron microscopy, UV–vis spectrophotometry and photoluminescence spectroscopy. The lattice parameters were calculated as a=7.4688 (4) A-ring ´, b=5.8171 (4) A-ring ´, c=9.9490 (5) A-ring ´ and V=432.2485 (5) Ǻ3. The average grain size of the samples was estimated as 42 nm using the modified Scherrer’s equation. Under near UV excitation, the sharp emission line at 560, 600, 646 and 704 nm due to characteristic transitions of Sm3+ were observed. The maximum PL emission intensity was observed at 1.5 mol.% of the Sm3+ ions. The band gap of the phosphor was calculated from diffused reflectance data and was found to be 3.74 eV. The CIE 1931 chromaticity coordinates (x, y) of the phosphor were (0.61, 0.39), in a shade of orange-red color. The potential applications of this material as a down conversion phosphor under blue light excitation were evaluated for possible application as a high color-purity phosphor in light emitting diodes (LEDs) that can fill the 590–600 nm gap.

  19. Suitable model for the calculation of the correlation between the real and the average specific heat capacity and possibilities of its application

    Directory of Open Access Journals (Sweden)

    Pejović Branko B.

    2013-01-01

    Full Text Available Starting from the definition of the average specific heat capacity for chosen temperature range, the analytic dependence between the real and the mean specific heat capacities is obtained using differential and integral calculation. The obtained relation in differential form for the defined temperature range allows for the problem to be solved directly, without any special restrictions on its use. Using the obtained relation, a general model in the form of a polynomial of arbitrary degree in the function of temperature was derived, which has more suitable and faster practical application and is more general in character than the existing model. New graphical method for solving the problem is obtained based on differential geometry and using the derived equation. This may also have practical significance since many problems in thermodynamics are solved analytically and graphically. This result was used in order to obtain the amount of specific heat exchanged using an analytical model or a planimetric method. In addition, this graphical solution was used for the construction of the diagram showing the dependence between the specific heat exchanged and temperature. This diagram also gives a simple graphical procedure for the calculation of the real and the average specific heat capacity for arbitrary temperature or temperature interval. The confirmation for all graphic constructions is obtained using the differential properties between thermodynamic units. In order for the graphical solutions presented to be applicable in practice, suitable ratio coefficients have been determined for all cases. Verification of the model presented, as well as the possibilities of its application, were given using several characteristic examples of semi-ideal and real gas. Apart from linear and non-linear functions in the form of polynomials, the exponential function of the dependence between specific heat capacities and temperature was also analysed in this process.

    Full Text Available The aims of this joint interdisciplinary project “Marmara” of ETH Zurich and the Istanbul Technical University (ITO are to study the effects of active tectonics as evidenced by geology, geodesy and seismology on hydrogeology and geothermics in selected areas along the North Anatolian fault zone. Within the framework of this project thermal water systems in seven different areas have been investigated or are under investigation up to now (SchindIer et al., 1993. For three study areas along the North Anatolian fault zone (from east to west of Kuzuluk/Adapazari, Bursa and of Canakkale the investigations with respect to the geological and hydrogeological features are complete. The now possible hydrogeological characterisation shows encouraging possibilities for the application of new methods like the electrical self potential method for the following reasons: 1 a fully interdisciplinary approach, including seismic survey with especially conceived network, geodetic survey to investigate tectonic movements by the GPS method, geothermic survey combined with geological mapping and hydrogeological investigations of normal mineral and thermal waters; 2 groundwaters of very different chemical and isotopical composition e.g.: Ca-HCO3-type thermal waters of up to 82 °C temperature and total mineralisation of 500 mg/I to 1500 mg/I in the Bursa area, Na-HCO3-type cold mineral waters of up to 2500 mg/I to thermal waters of same mineralisation of up to 80 °C temperature, containing large amounts of CO2 of up to 1 l per 1 kg of water (at surface conditions in the Kuzuluk area and Na-Cl-type waters presenting real thermal brines of up to 65 000 mg/I of total mineralisation and temperatures of up to 100 °C in the Canakkale area; 3 distinct types of hydrodynamic flow regime in areas of different geological and tectonic structure.

    A new sol-gel (SG) method is proposed to produce special bioactive glasses (BG_Ca family) characterized by a low tendency to devitrify. These formulations, derived from 45S5 Bioglass®, are characterized by a high content of CaO (45.6 mol%) and by a partial or complete substitution of sodium oxide with potassium oxide (total amount of alkaline oxides: 4.6 mol%), which increases the crystallization temperature up to 900°C. In this way, it is possible to produce them by SG preserving their amorphous nature, in spite of the calcination at 850°C. The sintering behavior of the obtained SG powders is thoroughly investigated and the properties of the sintered bodies are compared to those of the melt-derived (M) counterparts. Furthermore, the SG glass powders are successfully used to produce scaffolds by means of a modified replication technique based on the combined use of polyurethane sponges and polyethylene particles. Finally, in the view of a potential application for bone tissue engineering, the cytotoxicity of the produced materials is evaluated in vitro. PMID:25175252

    The objective of this work was to develop possible materials for optically stimulated luminescence (OSL) dosimetric applications in real-time measurement.A novel material of LiMgPO4:Tb,Sm,B was prepared by solid-state diffusion method at 900 ℃.The structure and optical properties of these phosphors were characterized by X-ray diffraction,fluorescence spectrophotometer,and OSL reader.The results showed that the full discrimination between the stimulation and emission spectra made them very fit for the optic-fibre dosimetry.The OSL vs.dose response was linear in the dose range of 0.1 to 216 Gy.It also showed a significant improvement in the stimulation time compared with LiMgPO4:Tb,B.Hence,the phosphor could be used in the real-time dosimeter based on the OSL technology for medical monitoring as well as for environmental dosimetry and space dosimetry.

  3. A high sensitivity heterodyne interferometer as a possible optical readout for the LISA gravitational reference sensor and its application to technology verification

    International Nuclear Information System (INIS)

    The space-based gravitational wave detector LISA (Laser Interferometer Space Antenna) utilizes a high performance position sensor in order to measure the translation and tilt of the free flying proof mass with respect to the optical bench. Depending on the LISA optical bench design, this position sensor must have up to pm/√Hz sensitivity for the translation measurement and up to nrad/√Hz sensitivity for the tilt measurement. We developed a heterodyne interferometer, combined with differential wavefront sensing, for the tilt measurement. The interferometer design exhibits maximum symmetry where measurement and reference arm have the same frequency and polarization and the same optical path-lengths. The interferometer can be set up free of polarizing optical components preventing possible problems with thermal dependencies not suitable for the space environment. We developed a mechanically highly stable and compact setup which is located in a vacuum chamber. We measured initial noise levels below 10 pm/√Hz (longitudinal measurement) for frequencies above 10 mHz and below 20 nrad/√Hz (tilt measurement) for frequencies above 1 mHz. This setup can also be used for other applications, for example the measurement of the coefficient of thermal expansion (CTE) of structural materials, such as carbon fiber reinforced plastic (CFRP).

  5. Study of the Ni-NiAl2O4-YSZ cermet for its possible application as an anode in solid oxide fuel cells

    International Nuclear Information System (INIS)

    Nanocrystalline Ni-NiAl2O4-YSZ cermet with a possible application as anode in solid oxide fuel cells (SOFCs) has been developed. The powders were prepared by using an alternative solid-state method that includes the use of nickel acetylacetonate as an inorganic precursor to obtain a highly porous material after sintering at 1400 oC and oxide reduction (NiO -Al2O3-YSZ → Ni-NiAl2O4-YSZ) at 800 oC for 8 h in a tubular reactor furnace using 10% H2/N2. Eight samples with 45% Ni and 55% Al2O3-YSZ in concentrations of Al2O3 oxides from 10 to 80 wt% of were mixed to obtain the cermets. The obtained material was compressed using unidirectional axial pressing and calcinations from room temperature to 800 oC. Good results were registered using a heating rate of 1 oC min-1 and a special ramp to avoid anode cracking. Thermal expansion, electrical conductivity, and structural characterization by thermo-mechanical analyser (TMA) techniques/methods, the four-point probe method for conductivity, scanning electron microscopy (SEM), x-ray energy dispersive spectroscopy (EDS), x-ray diffraction (XRD), and the Rietveld method were carried out. Cermets in the range 5.5 to 11% Al2O3 present a crystal size around 200 nm. An inversion degree (I) in the NiAl2O4 spinel structure of the cermets Ni-NiAl2O4-YSZ was found after the sintering and reduction processes. Good electrical conductivity and thermal expansion coefficient were obtained for the cermet with 12 wt% of spinel structure formation

    not possible to perform in all locations in the primary circuit. The combination well bench-marked measurements and computer model is therefore a prerequisite for optimisation of the HWC operation in a plant. In the text, the impact of Optimised HWC on cracking of austenitic materials is discussed. It is estimated that even lowering the potential by only 100 mV will reduce the crack growth rate by almost three times. A reduction by 200 mV could reduce the crack growth rate by eight times and 300 mV more than 20 times. The estimations are preliminary but indicate the potential efficiency of OHWC application. The calculations also show that both 'full' HWC operation and OHWC operation will lead to very different levels of the reducing conditions for various parts of the BWR systems. A more uniform, but high, level will be obtained by normal water chemistry. Finally, a number of areas where the current model can be applied or improved are presented.(abstract truncated)

    A variety of possible future analyses of HERA data in the context of the HERA data preservation programme is collected, motivated, and commented. The focus is placed on possible future analyses of the existing $ep$ collider data and their physics scope. Comparisons to the original scope of the HERA programme are made, and cross references to topics also covered by other participants of the workshop are given. This includes topics on QCD, proton structure, diffraction, jets, hadronic final states, heavy flavours, electroweak physics, and the application of related theory and phenomenology topics like NNLO QCD calculations, low-x related models, nonperturbative QCD aspects, and electroweak radiative corrections. Synergies with other collider programmes are also addressed. In summary, the range of physics topics which can still be uniquely covered using the existing data is very broad and of considerable physics interest, often matching the interest of results from colliders currently in operation.

  10. A study of the behavior of bi-oriented PVC exposed to ionizing radiation and its possible use in nuclear applications

    International Nuclear Information System (INIS)

    The paper discusses whether bi-oriented PVC, obtained by modifying the structures of polymers chains to enhance the mechanical properties of unplasticized PVC, could successfully replace metallic materials in industrial applications where radioactive fluids are processed and an intense field of ionizing radiation is present. Tests have been carried out in order to study the behavior of a commercial bi-oriented PVC when exposed to ionizing radiations. A numerical simulation allows comparing the effects of radiation expected on the pipe in nuclear industry applications with those resulting from the irradiation tests. Contamination and decontamination tests of bi-oriented PVC in contact with a radioactive solution have been performed too. Results show that the bi-oriented PVC can withstand high β and γ radiation doses (up to 100 kGy) without showing significant degradation in mechanical properties; bi-orientation of polymers chains in the bulk of material is not affected even to much higher doses (250 kGy); the decontamination of the material is satisfactory. The results suggest that tested commercial bi-oriented PVC could be considered in nuclear industry applications. - Highlights: • Bi-oriented PVC specimens have been irradiated with γ rays and β particles. • Up to 100 kGy mechanical properties of bi-oriented PVC are practically unchanged. • A numerical simulation allows estimating PVC piping minimum lifetime. • Achieved decontamination factors of PVC piping are satisfactory. • Results suggest bi-oriented PVC piping is suitable for nuclear applications

  12. Renewable resources - future possibilities

    International Nuclear Information System (INIS)

    The paper describes the Australian Cooperative Research Centre for Renewable Energy and Related Greenhouse Gas Abatement Technologies (ACRE), its technologies, commercial relationships and markets. The relevance of ACRE to developing country communities which lack reliable, adequate power supplies, is discussed. The opportunities for mutual collaboration between Australia and the developing countries in the application of renewable energy have never been stronger. Renewable energy promises real advantages to those who deploy it wisely, as well as significant job creation. Education at all level together with operational training, public awareness of what is possible and increased system reliability, are also vital ingredients for acceptance of these new technologies. They underpin successful commercialisation. The author concludes with the hope for a united international cooperative approach to the development of the renewable energy industry. (author)

Due to well-established data and MC sets, calibrations, and analysis procedures the manpower and expertise needed for a particular analysis is often very much smaller than that needed for an ongoing experiment. Since centrally funded manpower to carry out such analyses is not available any longer, this contribution not only targets experienced self-funded experimentalists, but also theorists and master-level students who might wish to carry out such an analysis.

    Full Text Available Cet article fait le point sur l'état de la recherche dans le domaine des réacteurs chimiques avec séparation par membrane intégrée et de leur applications dans le domaine du raffinage et de la pétrochimie. Trois applications potentiellement intéressantes sont identifiées et, pour chacune, les avantages de l'utilisation d'un réacteur à membrane sont discutés. Ce sont : la déshydrogénation du propane en propylène, la déshydrogénation d'un naphtène cyclohexanique et le vaporéformage du gaz naturel. Pour ces réactions, les membranes à base de palladium apparaissent les plus performantes compte tenu de leur tenue en température, de leur sélectivité et de leur perméabilité à l'hydrogène. Quelques éléments relatifs à leur développement sont présentés en conclusion. Recently, the use of membrane in reaction engineering has been more and more advocated. The selective separation of the products from the reaction mixture allows to achieve higher conversion or better selectivity or to operate under less severe conditions or with smaller units. This paper presents an update on the recent advances in the field of chemical membrane reactors and on their applications in refining and petrochemistry. Previous work. Most of the possible applications of membrane reactors in petroleum and petrochemical industry concern gaseous catalytic reactions. For this reason, gas permeation membranes are the primary component of membrane reactors. Gas permeation membranes present different types of physical structure : dense, microporous or asymmetric which is a combination of the two. Separating properties of dense membranes are function of the solubility and diffusivity of each gaseous component in the membrane material. For microporous membranes, they follow four mechanisms : Knudsen diffusion, surface diffusion, capillary condensation or molecular sieving. Although organic polymers are the common constituent of gas permeation membrane, their

  17. Opto-acoustic diagnostics of the thermal action of high-intensity focused ultrasound on biological tissues: the possibility of its applications and model experiments

    International Nuclear Information System (INIS)

    The possibility of using the opto-acoustic (OA) method for monitoring high-intensity ultrasonic therapy is studied. The optical properties of raw and boiled liver samples used as the undamaged model tissue and tissue destroyed by ultrasound, respectively, are measured. Experiments are performed with samples consisting of several alternating layers of raw and boiled liver of different thickness. The position and transverse size of the thermal lesion were determined from the temporal shape of the OA signals. The results of measurements are compared with the real size and position of the thermal lesion determined from the subsequent cuts of the sample. It is shown that the OA method permits the diagnostics of variations in biological tissues upon ultrasonic therapy. (special issue devoted to multiple radiation scattering in random media)

    Internet gaming disorder (IGD) may lead to many negative consequences in everyday life, yet there is currently no effective treatment for IGD. Cue-reactivity paradigm is commonly used to evaluate craving for substance, food, and gambling; cue exposure therapy (CET) is applied to treating substance use disorders (SUDs) and some other psychological disorders such as pathological gambling (PG). However, no study has explored CET's application to the treatment of IGD except two articles having implied that cues' exposure may have therapeutic effect on IGD. This paper reviews studies on cue-induced behavioral and neural changes in excessive Internet gamers, indicating that behavioral and neural mechanisms of IGD mostly overlap with those of SUD. The CET's effects in the treatment of SUDs and PG are also reviewed. We finally propose an optimized CET paradigm, which future studies should consider and investigate as a probable treatment of IGD.

    The characterization of plasma bursts produced after the pinch phase in a plasma focus of hundreds of joules, using pulsed optical refractive techniques, is presented. A pulsed Nd-YAG laser at 532 nm and 8 ns FWHM pulse duration was used to obtain Schlieren images at different times of the plasma dynamics. The energy, interaction time with a target, and power flux of the plasma burst were assessed, providing useful information for the application of plasma focus devices for studying the effects of fusion-relevant pulses on material targets. In particular, it was found that damage factors on targets of the order of 10{sup 4} (W/cm{sup 2})s{sup 1/2} can be obtained with a small plasma focus operating at hundred joules.

  3. Possibilities for the application of process steam from nuclear steam supply systems for production and treatment of liquid and gaseous prime movers

    International Nuclear Information System (INIS)

    Because of the limited worldwide resources of crude, a lack of liquid hydrocarbons, namely of petrol and fuel oil will arise in the forthcoming years. On the other hand, these secondary energies cover today more than 40% of the worldwide demand because of their large spectrum of applications. In order to optimize the utilization of the existing resources it is recommended to cover the energy consumption of the production and the upgrading of the crude wherever it is feasible by alternative energy sources, i.e. by steam and electricity from the commercally available nuclear power stations with light water reactors. The predictable escalation of the prices of crude as well as the increasing achievable revenues for light and medium products as a result of the decreasing reserves should be an economical incentive for the owners of such plants and installations. Similar advantages are also offered to owners of important plants for natural gas liquefaction. (orig.)

    2010-01-01

    We describe a detector of alpha particles based on wire type counters (single-wire and multiwire) operating in ambient air at high gas gains (100-1000). The main advantages of these detectors are: low cost, robustness and ability to operate in humid air. The minimum detectable activity achieved with the multiwire detector for an integration time of 1 min is 140 Bq per m3, which is comparable to that featured by commercial devices. Owing to such features the detector is suited for massive application, for example for continuous monitoring of Rn or Po contaminations or, as discussed in the paper, its use in a network of Rn counters in areas affected by earth-quakes in order to verify, on a solid statistical basis, the envisaged correlation between the sudden Rn appearance and a forthcoming earthquake.

    Background: Amifostine is a new cancer-supporting agent to protect normal tissue in patients receiving radio-chemotherapy. The main question of our study is whether the application of amifostine can be limited on the duration of chemotherapy in patients with advanced head and neck tumors undergoing radio-chemotherapy. Patients and methods: In a randomized study 14 patients were treated with amifostine (500 mg, day 1 to 5 and 29 to 33) during concurrent radio-chemotherapy with carboplatin (70 mg/m{sup 2}, day 1 to 5 and 29 to 33), 14 patients were treated without amifostine. The analyzed parameters were dermatitis, mucositis, skin temperature, white blood and platelet count, creatinine and scintigram of salivary glands. Median survival of the amifostine group was 19 months, of the control group 10 months. Results: There were no relevant differences in all analyzed parameters between both arms of the study. Conclusion: Our form of amifostine application is probably not able to obtain a relevant reduction of the toxicity of radio-chemotherapy. (orig.) [German] Hintergrund: Amifostin wird supportiv eingesetzt, um die Toxizitaet einer Chemotherapie und/oder Bestrahlung zu reduzieren. In einer randomisierten Studie untersuchten wir, ob die Amifostin-Gabe zeitlich auf die Tage der Chemotherapie bei simultaner Radiochemotherapie begrenzt werden kann. Patienten und Methode: Bisher wurden 28 Patienten mit fortgeschrittenen Tumoren im Kopf-Hals-Bereich randomisiert. Im Behandlungsarm (14 Patienten) wurde Amifostin (500 mg) an den Tagen 1 bis 5 und 29 bis 33 einer Radiochemotherapie mit Carboplatin (70 mg/m{sup 2}; Tag 1 bis 5 und 29 bis 33) appliziert. Bei 14 Patienten erfolgte die Radiochemotherapie ohne Amifostin. Die untersuchten Parameter waren Haut- und Schleimhautreaktion, Haupttemperatur, Leukozyten, Thrombozyten, Kreatinin und Speicheldruesenszintigraphie.

    Full Text Available This paper investigated the effect of ethanol on the quality of the extract of pine produced from low-grade raw materials and their processing properties. We studied the relationship between views of the extractant and the degree of modification of collagen - the main skins' protein by simulating the process of tanning. The products of dissolution of collagen (PDC treated with ethyl extract of pine were used as the model. The degree of modification was determined by differential scanning calorimetry. The investigations revealed that the alcohol extract of pine features a large tar content and a high degree of purity (~92,6%. Interaction between extractives and collagen goes mainly on amide nitrogen and the side carboxyl groups, with ε-amino groups and phenolic hydroxyl groups - that have probably been blocked by hydrogen bondsare – are being released. Heat resistance of coats derived from the tanned PDC is high enough, it can be concluded that there may be the possible use of alcohol extracts of pine in the leather and fur industry as a tanning agent.

  8. Extending Performance and Evaluating Risks of PV Systems Failure Using a Fault Tree and Event Tree Approach: Analysis of the Possible Application

    Energy Technology Data Exchange (ETDEWEB)

    Colli A.

    2012-06-03

    Performance and reliability of photovoltaic (PV) systems are important issues in the overall evaluation of a PV plant and its components. While performance is connected to the amount of energy produced by the PV installation in the working environmental conditions, reliability impacts the availability of the system to produce the expected amount of energy. In both cases, the evaluation should be done considering information and data coming from indoor as well as outdoor tests. In this paper a way of re-thinking performance, giving it a probabilistic connotation, and connecting the two concepts of performance and reliability is proposed. The paper follows a theoretical approach and discusses the way to obtaining such information, facing benefits and problems. The proposed probabilistic performance accounts for the probability of the system to function correctly, thus passing through the complementary evaluation of the probability of system malfunctions and consequences. Scenarios have to be identified where the system is not functioning properly or at all. They are expected to be combined in a probabilistic safety analysis (PSA) based approach, providing not only the required probability, but also being capable of giving a prioritization of the risks and the most dominant scenario associated to a specific situation. This approach can offer the possibility to highlight the most critical parts of a PV system, as well as providing support in design activities identifying weak connections.

  9. Microscopic nature of the extremely high specific heat of rare earth intermetallic compounds at low temperatures and the possibility of its application in technical superconductivity

    International Nuclear Information System (INIS)

    The presence of an unfilled f-electron shell in rare earth intermetallic compounds under conditions of strong electron correlation between localized and delocalized electrons is responsible for the formation of local magnetic moments. According to the data of neutron, synchrotron, and other investigations of a number of such systems, the interaction of these moments with the local crystalline environment, hybridization with conduction electrons, f-f correlations (i.e., both one-site and cooperative phenomena), and combinations of these main effects form the physical base for the reconstruction of the excitation spectrum of an f-electron system and appearance of pronounced specific features of thermodynamic characteristics. The range of characteristic temperatures of these anomalies is determined by the interaction energy, which generally corresponds to the range 1-100 K. For some intermetallic compounds, the additional component of the specific heat (of electron origin) may greatly (by two to three orders of magnitude) exceed the specific heat of conventional structural materials. This feature makes it possible to consider such systems as promising functional materials (a kind of thermodynamic dampers) capable of compensating for various thermal perturbations in low-temperature super-conducting magnetic systems

With respect to potential radiation hazards, the Agency has jointly developed the International Basic Safety Standards with the World Health Organization, and the Food and Agriculture Organization. These standards, known as the BSS, cover a wide range of situations that give rise or could give rise to exposure to radiation, such as the radiation hazard posed by depleted uranium (DU). Based on the information currently available, DU ammunitions do not appear to present a significant risk to health from a radiological point of view. Since only limited studies have been undertaken in post-conflict areas where DU ammunitions were used, further assessment and studies of DU in such areas would increase the confidence in this observation. In addition to radiological assessment, the IAEA is also developing a training course to assist Member States in analytical methods and techniques that could be used to detect and measure DU in post-conflict areas

    Pimelodus (Pimelodidae) is a genus comprising a group of South American species with complex taxonomic relationships. Cytogenetics, polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP), and sequencing data of mitochondrial genes were analyzed to characterize 4 Pimelodus species: P. fur, P. heraldoi, P. maculatus, and Pimelodus sp. All populations presented 2n=56 chromosomes and distinct karyotypic formulae. The heterochromatin distribution pattern and the number and location of 5S and 18S rDNA sites are discussed. The application of PCR-RFLP markers and sequencing of mitochondrial DNA genes provided species-specific haplotypes, which allowed us to differentiate the species studied. The mitochondrial gene sequences presented nucleotide mutations in the restriction sites and throughout the sequences, and they were mostly related to synonymous substitutions in the coded proteins; however, they did not affect the protein and its function. Comparing the data obtained using these 3 methodologies, the existence of a species complex in P. maculatus along the basins studied might be inferred, showing that cytogenetics is an important tool in studies focusing on the conservation or management of both natural and captive populations of these fishes.

  12. Possibility of application of solid oxide electrolysis cell on a smart iron-making process based on an active carbon recycling energy system

    International Nuclear Information System (INIS)

    Efficient carbon dioxide (CO2) reduction into carbon monoxide (CO) is required to establish a smart iron-making process based on an active carbon recycling energy system (iACRES). A disk-type solid oxide electrolysis cell (SOEC) was prepared and examined experimentally for application to the CO2 reduction process in iACRES. A SOEC with a cathode|electrolyte|anode structure of Ni-YSZ|YSZ|La0.6Sr0.4Co0.2Fe0.8O3-δ was fabricated. The electrolysis of carbon dioxide was conducted at 800-900°C. A current density of 107.1 mA cm-2 was measured between the cathode and anode at 900°C and at 2.52 V. The production rates of CO and O2 were in agreement with the theoretical values determined using Faraday's law. Evaluation of iACRES using the experimental results indicated that an estimated 0.73 high-temperature gas cooled reactor units as the primary energy source for CO2 reduction and a SOEC surface area of 0.098 km2 were required for the reduction of 30% CO2 in blast furnace gas emitted from a conventional blast furnace.

  13. The effect of 10 : 1 compression and soft copy interpretation on the chest radiographs of premature neonates with reference to their possible application in teleradiology

    International Nuclear Information System (INIS)

    The aim of the study was to assess the potential application of teleradiology in the neonatal intensive care unit (NICU) by ascertaining whether any decrease in conspicuity of anatomic detail or interventional devices in the chest radiographs of premature infants is caused by picture archiving and communication system (PACS)-based soft copy interpretation of 10 : 1 compressed images. One hundred digital chest radiographs of low-birthweight infants were obtained in the NICU using a storage phosphor system. Laser-printed images were interpreted and the data set for each radiograph was then irreversibly compressed by a 10 : 1 ratio. Four radiologists with extensive PACS experience used a five-point grading system to score laser-printed hard copy images for the visibility of six parameters of anatomic landmarks and interventional devices in the chest. Compressed soft copy images displayed on 2K PACS workstation were subsequently scored using the same approach. Statistical manipulation demonstrated no loss of anatomic detail in five of the six parameters scored, with minimal difference in one landmark, the retrocardiac lung assessment. While further study is required to assess the clinical impact of the variance noted when evaluating lung parameters, the preservation or improvement of information in the remaining parameters following irreversible compression and soft copy interpretation is promising for the potential use of teleradiology in this population.

    Full Text Available This article presents results of the experimental trial of combination of the chemical method of water glass molding sands’ curing, used in foundry industry, with an innovative microwave heating. The research objective was to indicate at new areas of microwave energy application. The sands prepared, according to recommendations for curing technology, with the use of ethylene glycol diacetate, have been subject to microwave influence. The attempt at determination of microwave influence on qualitative changes of the binding bridges created during the curing process concerned such parameters as: bending and tensile strength, permeability as well as wear resistance. Moreover,we also determined the influence of microwave curing on the phenomena accompanying the process as well as bond stability (storage time of the prepared molding and core sands. It has been found, basing on the result analysis, that the innovative microwave heating might constitute a very good supplementation of the ester curing method. The advantages of the combined chemical and microwave gelation process include, among others, improvement of the described resistance and technological parameters as well as significant decrease of preparation time of foundry moulds and cores. The subject discussed in this article will be continued in its second part.

    The Pelletron Accelerator of positive ions 3 MV in the Institute of Physics of UNAM has characteristics that make it useful for the application to the radiations dosimetry. It is ideal for studying the detailed mechanisms of the radiation interaction with matter, therefore it can be applied to know the performance of dosemeters. With this device can be accelerated almost any type of ion, including He, but excepting the others noble gases. The energies of the disposable ions are in the interval 1 MeV until several MeV, depending of the state of charge selected, the energy can be varied continuously with accuracy of some KeV. It can be achieved streams from 10{sup 4} until 10{sup 6} ions/cm{sup 2}, allowing studies of individual events (tracks) or of collective processes. the beam size can be varying from a diameter 1 mm until 5 cm. It is also took in account with detectors and other techniques associated that can be combined for supporting studies, as surface barrier detectors and of other types, as well as the RBS, PIXE, RN techniques and channeling.

  16. Development of Ag doped crystalline SiO2 for possible applications in real-time in-vivo OSL dosimetry

    International Nuclear Information System (INIS)

    A new Ag-doped crystalline SiO2 based OSL phosphor is developed. This phosphor shows good OSL properties and the sensitivity is comparable to that of the commercial Al2O3:C. For the luminescence integrated over initial 3s, BSL (blue stimulated luminescence) and GSL (green stimulated luminescence) sensitivities were found to be 0.54 and 3.1 times the respective BSL and GSL sensitivities of the commercial Al2O3:C. The PL emission is found to vary from UV to visible range with the change in the Ag concentration. Thus the material can be used as BSL or GSL phosphor. The simple preparation procedure, fast decay, very good sensitivity will make this phosphor suitable for real-time dosimetric applications, using OSL technique. - Highlights: • Polycrystalline SiO2 is synthesized chemically. • The synthesized material is mixed phase compound with tridymite and quartz as major phase. • Ag+ luminescence is observed and photoluminescence was found to be dependent on Ag concentration. • Samples show intense Blue as well as Green stimulated luminescence comparable to the commercial Al2O3:C. • This material will be promising phosphor for online dosimetry using OSL

  17. Application of MODIS Products to Infer Possible Relationships Between Basin Land Cover and Coastal Waters Turbidity Using the Magdalena River, Colombia, as a Case Study

    Basin development and consequent change in basin land cover have been often associated with an increased turbidity in coastal waters because of sediment yield and nutrients loading. The later leads to phytoplankton abundance further exacerbating water turbidity. This subsequently affects biological and physical processes in coastal estuaries by interfering with sun light penetration to coral reefs and sea grass, and even affecting public health. Therefore, consistent estimation of land cover changes and turbidity trend lines is crucial to design environmental and restoration management plans, to predict fate of possible pollutants, and to estimate sedimentary fluxes into the ocean. Ground solely methods to estimate land cover change would be unpractical and traditional methods of monitoring in situ water turbidity can be very expensive and time consuming. Accurate monitoring on the status and trends of basin land cover as well as the water quality of the receiving water bodies are required for analysis of relationships between the two variables. Use of remote sensing (RS) technology provides a great benefit for both fields of study, facilitating monitoring of changes in a timely and cost effective manner and covering wide areas with long term measurements. In this study, the Magdalena River basin and fixed geographical locations in the estuarine waters of its delta are used as a case to study the temporal trend lines of both, land cover change and the reflectance of the water turbidity using satellite technology. Land cover data from a combined product between sensors Terra and Aqua (MCD12Q1) from MODIS will be adapted to the conditions in the Magdalena basin to estimate changes in land cover since year 2000 to 2009. Surface reflectance data from a MODIS, Terra (MOD09GQ), band 1, will be used in lieu of in situ water turbidity for the time period between 2000 and present. Results will be compared with available existing data.

    In this study, it was the first time that we simultaneously quantified nimesulide and its possible metabolites M1, M2, M3 and M4 by employing liquid chromatography-tandem mass spectrometry (LC-MS/MS). Nimesulide-d5 was used as internal standard (IS) for validation. Analytes and IS were recovered from human plasma by protein precipitation with acetonitrile. Prepared plasma samples were analyzed under the same LC-MS/MS conditions, and chromatographic separation was realized by using an Ultimate C18 column, with run time being 5min for each sample. Our results showed that various analytes within their concentration ranges could be quantified accurately by using the method. Mean intra- and inter-day accuracies ranged from -4.8% to 4.8% (RE), and intra- and inter-assay precision ≤6.2% (RSD). The following parameters were validated: specificity, recovery, matrix effects, dilution integrity, carry-over, sample stability under a variety of storage and handling conditions (room temperature, freezer, freeze-thaw and post-preparative) and stock solution stability. Pharmacokinetics of nimesulide and its metabolites were calculated based on the analysis of samples collected from twelve Chinese healthy volunteers after single oral dose of 100mg nimesulide tablets. By applying the pharmacokinetic determination into human samples, we preliminarily detected a new metabolite of nimesulide (M4*), and the concentration of M4* was relatively higher in plasma. Furthermore, we predicted part of conceivable metabolism pathway in plasma of after oral administration of 100mg nimesulide tablets. This research provided an experimental basis for further studies on metabolic activation and biotransformation of nimesulide, and for more comprehensive conjecture of its metabolic pathways.

  19. Sulfated polysaccharide, curdlan sulfate, efficiently prevents entry/fusion and restricts antibody-dependent enhancement of dengue virus infection in vitro: a possible candidate for clinical application.

    Directory of Open Access Journals (Sweden)

    Koji Ichiyama

    Full Text Available Curdlan sulfate (CRDS, a sulfated 1→3-β-D glucan, previously shown to be a potent HIV entry inhibitor, is characterized in this study as a potent inhibitor of the Dengue virus (DENV. CRDS was identified by in silico blind docking studies to exhibit binding potential to the envelope (E protein of the DENV. CRDS was shown to inhibit the DENV replication very efficiently in different cells in vitro. Minimal effective concentration of CRDS was as low as 0.1 µg/mL in LLC-MK2 cells, and toxicity was observed only at concentrations over 10 mg/mL. CRDS can also inhibit DENV-1, 3, and 4 efficiently. CRDS did not inhibit the replication of DENV subgenomic replicon. Time of addition experiments demonstrated that the compound not only inhibited viral infection at the host cell binding step, but also at an early post-attachment step of entry (membrane fusion. The direct binding of CRDS to DENV was suggested by an evident reduction in the viral titers after interaction of the virus with CRDS following an ultrafiltration device separation, as well as after virus adsorption to an alkyl CRDS-coated membrane filter. The electron microscopic features also showed that CRDS interacted directly with the viral envelope, and caused changes to the viral surface. CRDS also potently inhibited DENV infection in DC-SIGN expressing cells as well as the antibody-dependent enhancement of DENV-2 infection. Based on these data, a probable binding model of CRDS to DENV E protein was constructed by a flexible receptor and ligand docking study. The binding site of CRDS was predicted to be at the interface between domains II and III of E protein dimer, which is unique to this compound, and is apparently different from the β-OG binding site. Since CRDS has already been tested in humans without serious side effects, its clinical application can be considered.

  20. Physics with Ultracold and Thermal Neutron Beams: Testing and possible application of 'low temperature Fomblin' in a neutron lifetime experiment. Final report

    International Nuclear Information System (INIS)

    This project has been focused on a measurement of the mean lifetime τn of the free neutron with a precision better than 0.1%. The neutron β-decay n → p + e- + (bar ν)e + 783 keV into a proton, electron and electron antineutrino is the prototype semi-leptonic weak decay, involving both leptons and hadrons in the first generation of elementary particles. Within the standard V-A theory of weak interaction, it is governed by only two constants: the vector coupling constant gV, and axial vector constant gA. The neutron lifetime has been measured many times over decades, and the present (2004) world-average, τn = 885.7 ± 0.8 s, has a weighted error of ∼0.1% while individual uncertainties are typically 2-10 seconds for high precision data. The highest precision claimed by an individual measurement is ∼0.15%. An improvement is required to resolve issues of the Standard Model of the electro-weak interaction as well as of astrophysics and of Big Bang theories. The focus in astrophysics is the solar neutrino deficit problem, which requires a precise value of gA. Big Bang theories require a precise τn-value to understand the primordial He/H ratio. The strong interest of particle physicists in τn is mainly based on a possible difficulty with the Cabibbo Kobayashi Maskawa (CKM) matrix, which describes the mixing of quark mass states by the weak interaction. Nuclear, neutron, and pion decay data, probing the mixing amplitude Vud within the first quark generation, in combination with K and B meson decay data, which probe the second and third generation (Vus and Vub), indicate a departure from the unitarity demanded by all gauge-invariant theories. The deviation of the first-row sum |Vud|2 + |Vus|2 + |Vub|2 from unity is on the 2.3 sigma level. Including a new value for Vus would remove the discrepancy; but the authors of note an inconsistency requiring clarification. The largest contribution to this sum is |Vud|2 which is determined most sensitively by the neutron

  3. Exploiting geometrical irradiation possibilities in MRT application

    International Nuclear Information System (INIS)

    Microbeam Radiation Therapy (MRT) has the potential to treat infantile brain tumors when other kinds of radiotherapy would be excessively toxic to the developing normal brain. MRT uses extraordinarily high doses of X-rays but provides unusual resistance to radioneurotoxicity, presumably from the rapid migration of regenerative endothelial cells from dose 'valleys' into dose 'peaks', i.e., into directly irradiated micro-slices of tissues. We will present a novel irradiation geometry which results in a tolerable valley dose for the normal tissue and a decreased peak-to-valley dose ratio (PVDR) in the tumor area by applying an innovative cross-firing technique. We propose an MRT technique to orthogonally crossfire two arrays of parallel, nonintersecting, mutually interspersed microbeams that produces tumoricidal doses with small PVDRs where the arrays meet and tolerable radiation doses to normal tissues between the microbeams proximal and distal to the tumor in the paths of the arrays

    The idea of information ether as the unitary information field is developed. It rests on the assumption that the notion of information is a fundamental category in the description of reality and that it can be defined independently from the notion of probability itself. It is shown that the information ether provides a deterministic background for the nonlinear wave hypothesis and quantum cybernetics. (orig.)

    Amaranth flour--a product of amaranth seeds processing--is a valuable industrial raw material that has an unique chemical composition and may be used for nutrition of people suffering from intolerance to traditional cereals protein, including celiac disease patients. The research aim was to study the composition of amaranth flour of two types compared with semolina which is traditionally used for nutrition by Russian population, as well as to compare the composition of milk amaranth flour porridge with milk semolina porridge. The composition of amaranth whole-ground flour and amaranth flour of premium grade processed from amaranth seeds grown in Voronezh region has been researched. It is to be noted that protein content in amaranth flour was 10.8-24.3% higher than in semolina, and its biological value and NPU-coefficient were higher by 22.65 and 46.51% respectively; lysine score in amaranth flour protein of premium grade came up to 107.54%, and in semolina protein only 40.95%. The level of digestible carbohydrates, including starch, was lower in amaranth flour than in semolina by 2.79-12.85 and 4.76-15.85% respectively, while fiber content was 15.5-30 fold higher. Fat content in amaranth flour of premium grade was 2,4 fold lower than in whole-ground amaranth flour but it was 45% higher than in semolina. The main advantage of amaranth flour protein compared to wheat protein is the predominance of albumins and globulins and a minimal content of prolamines and alpha-gliadin complete absence. The specifics of chemical composition allow the amaranth flour to be recommended for being included into nutrition of both healthy children and adults and also celiac disease patients. PMID:25059059

  9. Current puzzles and future possibilities

    International Nuclear Information System (INIS)

    Four current puzzles and several future experimental possibilities in high-energy nuclear collision research are discussed. These puzzles are (1) entropy, (2) hydrodynamic flow, (3) anomalon, and (4) particle emission at backward angles in proton-nucleus collisions. The last one seems not to be directly related to the subject of the present school. But it is, because particle emission into the region far beyond the nucleon-nucleon kinematical limit is an interesting subject common for both proton-nucleus and nucleus-nucleus collisions, and the basic mechanism involved is strongly related in these two cases. Future experimental possibilities are described which include: (1) possibilities of studying multibaryonic excited states, (2) applications of neutron-rich isotopes, and (3) other needed experimental tasks. 72 references

  14. High-dose-rate brachytherapy with local injection of bleomycin for N0 oral tongue cancer. Possibilities of the control of tumor implant by inserting applicators and the decrease in tumor dose

    International Nuclear Information System (INIS)

    Twenty-eight patients with N0 oral tongue cancer were treated with high-dose-rate (HDR) interstitial brachytherapy combined with local injection of bleomycin between December 1997 and June 2001 at the Department of Radiology, National Kyushu Medical Center Hospital. A median dose of 5 mg of bleomycin was injected locally, and 16-20 Gy was delivered to the area surrounding applicators for control of the tumor implant during the initial two days. The two-year local recurrence-free survival rate was 96% [T1, 2: 100% (8/8, 15/15), T3: 80% (4/5)]. The two-year secondary neck node metastasis rate was 7.1% [T1: 12.5% (1/8), T2: 6.7% (1/15), T3: 0% (0/5)]. There were no tumor implants in any patients. We tried to decrease the minimal tumor dose step by step. The groups with median minimal tumor doses of 60 Gy, 50 Gy, and 40 Gy had local recurrence rates of 12.5% (1/8), 0% (0/14), and 0% (0/6), respectively. Local recurrence rates were not increased by decreasing the minimal tumor dose. Two patients (7%) had secondary neck node metastasis. Late adverse effects were tongue ulcer: 11% (3/28), oral floor ulcer: 4% (1/28), and osteonecrosis: 4% (1/28). These results suggest that control of the tumor implant and the decrease in minimal tumor dose below 60 Gy may be possible with the local injection of bleomycin and delivery of doses to the area surrounding the applicators when N0 tongue cancer is treated using 192Ir-HDR brachytherapy.

    In this paper the synthesis and study of thin films of titanium oxide is reported, as well as those that were surface modified with palladium nanoparticles Pd/TiO{sub 2}. First, the TiO{sub 2} films are grown on substrates of soda-lime glass using chemical sol-gel route and the repeated immersion procedure. The salt precursor titanium oxy-acetylacetonate to 0.2 M, in the solvent 2-methoxyethanol and monoethanolamine was used as stabilizer. The number of used immersions gave an average thickness estimate for these films of 172.8 nm. Second, the series of Pd/TiO{sub 2} films surface modified were obtained from a solution of palladium nitrate dehydrate at low concentration, with the same procedure. The films grown TiO{sub 2} and those surface-modified films were characterized in its structure by X-ray diffraction, morphology by scanning electron microscopy, the topography with atomic force microscopy, optical properties by UV-Vis, among others. Photoluminescence properties and/or possible applications in photo catalysis are reported in this paper. (Author)

  17. Possibility of hyperbolic tunneling

    International Nuclear Information System (INIS)

    Traversable wormholes are primarily useful as 'gedanken experiments' and as a theoretician's probe of the foundations of general relativity. In this work, we analyze the possibility of having tunnels in a hyperbolic spacetime. We obtain exact solutions of static and pseudo-spherically symmetric spacetime tunnels by adding exotic matter to a vacuum solution referred to as a degenerate solution of class A. The physical properties and characteristics of these intriguing solutions are explored, and through the mathematics of embedding it is shown that particular constraints are placed on the shape function, that differ significantly from the Morris-Thorne wormhole. In particular, it is shown that the energy density is always negative, and the radial pressure is positive, at the throat, contrary to the Morris-Thorne counterpart. Specific solutions are also presented by considering several equations of state, and by imposing restricted choices for the shape function or the redshift function.

Cheminformatics developers often need to choose between “mainstream” (i.e., accepted, expected) and novel, leading-edge tools, with an increasing trend for open science. Possible futures...... for cheminformatics include the worst case scenario (lack of funding, no creative usage), as well as the best case scenario (complete integration, from systems biology to virtual physiology). As “-omics” technologies advance, and computer hardware improves, compounds will no longer be profiled at the molecular level......, but also in terms of genetic and clinical effects. Among potentially novel tools, we anticipate machine learning models based on free text processing, an increased performance in environmental cheminformatics, significant decision-making support, as well as the emergence of robot scientists conducting...

    Migraine with and without aura (MA and MO, respectively) have a strong genetic basis. Different approaches using linkage-, candidate gene- and genome-wide association studies have been explored, yielding limited results. This may indicate that the genetic component in migraine is due to rare...... variants; capturing these will require more detailed sequencing in order to be discovered. Next-generation sequencing (NGS) techniques such as whole exome and whole genome sequencing have been successful in finding genes in especially monogenic disorders. As the molecular genetics research progresses......, the technology will follow, rendering these approaches more applicable in the search for causative migraine genes in MO and MA. To date, no studies using NGS in migraine genetics have been published. In order to gain insight into the future possibilities of migraine genetics, we have looked at NGS studies...

However, the proper conduct of these assessments can be put in check, that is verified by metaevaluations. Metaevaluation was defined as the evaluation of an evaluation. Thus, this paper presents some approaches that represent a variety of contributing authors to conduct metaevaluation. Approaches are applicable to summative and formative metaevaluations. Some examples of metaevaluations already developed are part of the article, which highlights the possibilities of using the last version of international standards of evaluation published by the Joint Committee on Standards for Evaluations.

  6. Comparison of different application systems and CT-assisted treatment planning procedures in the treatment of primary endometrium carcinoma. Is it technically possible to include the whole uterus volume in the volume treated by brachytherapy?

    International Nuclear Information System (INIS)

    In a consecutive series of 10 patients with primary irradiated endometrial carcinoma we analyzed the correlation between target volume and treated volume using either standard 1-channel applicators or individual Heyman-applicators. Application of the ovoids was followed by a planning CT scan for all patients. Based on this, target volume (uterus volume) was estimated on a 3D-planning system. According to the measurable length of the uterus cavity we determined the corresponding standard 1-channel applicator and calculated the respectively treated volume. Estimating the advantages of an optimized treatment planning strategy for individual Heyman-applications we compared the treated volumes, which result from a standardized and optimized treatment planning procedure. The mean uterus volume was 180 cm3 (range 57 to 316 cm3). Asymmetric uterus configurations with longitudinal or sagittal side differences exceeding 1 cm were found in 40% of the cases. Using standard 1-channel applicators on average 47% (range 25 to 89%) of the uterus volume were enclosed by the treated volume compared to 70% for Heyman-applications. Differentiating these individual applications according to the variable treatment modality values of mean 66% (range 36 to 110%) for the standardized and 73% (range 48 to 95%) for the optimized treatment planning strategy were found. Moreover optimized planning modalities led to an improved coverage of the target volume in 5 out of 10 cases with an increase in volume of 20% on average (range 11 to 32%). In 3 cases changes of less than 5% were noticed (no improvement). In order to protect organs at risk treated volume had to be decreased in 2 cases for 19% and 40% respectively. (orig./MG)

    This report presents the result of phase 2 of 'Possibilities to achieve better performance at the Pulp and Paper Industry bark boilers by optimised combustion control'. The project was initiated to generate know-how for coping with the special demands that exist for the bark boilers, with rapid changes of loads and fuel quality. The fuel comprises of different types of wood chips, bark and residue fibres with a wide range of moisture contents. In the future it is expected that these boilers, working under difficult conditions, will have the same environmental requirements as district heating boilers. Phase 1 of the project 'Diagnosis and analysis of existing boilers' was published as SVF report 660. The report contains an analysis of 21 Swedish bark boilers. Phase 3 which has already been started and includes the demonstration and evaluation of modified bark boilers. The report describes and explains different types of suitable boiler modifications, based on four selected typical boilers. The work has included measurements in- and outside the furnace, tests and mathematical simulation in two steps. The first basic simulations was made to get a good picture of the present situation and the later modification simulations to test the practical effects of different combustion solutions. The presentation in the report has been aimed at describing concrete solutions, but most of all to give a better understanding of the hows and whys and the general ways of solving existing problems. The opinions of how to modify a boiler to get the best performance will vary, but the basic chemical-physical laws will remain unchanged. The hope of the authors is that this report will serve as a basis for choosing between proposed different solutions and to inspire engineers and owners to modify bark boilers using the technology of tomorrow.

    Full Text Available We investigate the possibility of realizing unconventional superconductivity in doped band insulators on the square and honeycomb lattices. The latter lattice is found to be a good candidate due to the disconnectivity of the Fermi surface. We propose applying the theory to the superconductivity in doped layered nitride β-MNCl (M= Hf, Zr. Finally, we compare two groups of superconductors with disconnected Fermi surface, β-MNCl and the iron pnictides, which have high critical temperature Tc, despite some faults against superconductivity are present.

    Full Text Available While maintaining its inherent characteristics, inspired by a violent logic of domination, the Mafia is evolving, becoming capable of dealing with society in different contexts and in ways that are beyond its archaic methods of operation.In this sense, the Italian penal jurisprudence has authorized the institution of the crime of possible complicity in mafia organized crime with the attempt to combat such a form of flanking on mafia association and contribution, perpetrated by outsiders to the traditional social environment of this phenomenon.A carefully reading of this offense allows the author to trace the evolution of the Supreme Court jurisprudence on possible complicity in mafia organized crime, grasping the critical issues and suggesting a possible legislative solution.Même si ses caractéristiques typiques, inspirées par une logique violente de domination, restent inchangées, la mafia évolue, devenant capable d’établir des relations avec la société globale grâce à des modes opératoires différents par rapport à ses propres méthodes archaïques. En ce sens, la jurisprudence a autorisé l’utilisation du concours externe en association mafieuse pour essayer de combattre les formes de soutien et de contribution à l’association mafieuse assurées par des personnes étrangères au contexte social traditionnel du phénomène. Une lecture prudente de ce délit permet d’examiner l’évolution jurisprudentielle de la Cour de Cassation afin de saisir les criticités et d’envisager une possibilité de solution normative.

    non-linéarité sous fort confinement, et qui pourraient engendrer un signal résultant d'une interaction onde-onde . Tempérant ce pessimisme, il faut noter qu'un éventuel signal d'interaction non linéaire présenterait l'avantage, quant à sa détection, d'être dans une bande de fréquence différente de celle des ondes utilisées pour l'engendrer. Bien que nous n'ayons pas connaissance d'essais d'application actuels, les perspectives paraissent plus encourageantes dans le domaine du génie civil ou minier. C'est dans le domaine diagraphique, où des distances de propagation sont très faibles, que des applications semblent possibles à moyen terme. Si l'on en juge par le dépôt très récent de plusieurs brevets, les compagnies de logging poursuivraient des recherches dans cette voie. A general and important characteristic of rocks is their elastically nonlinear behavior resulting in significant effects on wave propagation. The nonlinear response of rock is a direct consequence of the compliant nature of rock : the macro-and micro-structure of the material (microcracks, grain-to-grain contacts, etc. . As a result, the material modulus varies as a function of the applied pressure. Interest has grown significantly in the last several years, as illustrated by the increasing number of publications regarding this topic. Here we present a summary of the fundamentals of theory and of experimental observations characteristic of rock, and we address possible applications in geophysics. Two disciplines regarding the nonlinear elasticity of rock have been developed over recent years in tandem :- Acoustoelasticity where wave propagation in statically, prestressed materials is studied. Here one relates the variation in applied pressure to the elastic wavespeed in order to extract the nonlinear coefficients. This area of study includes the topic of stress-induced anisotropy. - Acoustic nonlinearity where we are interested in the temporary and local variation in the elastic

    Hardly the role and the importance of Classical-Invariant Theory is the history of mathematics (say, between - 1850 and - 1920) can be fully appreciated by a nonspecialist. In this study, it was firstly purposed to provide a compact sketch of its foundations starting from (and keeping the framework of) some very basic ideas in the equation theory; and then, after reviewing a couple of classical examples, to illustrate a number of (presumably new) applications to physics, with special reference to constitutive relations in continuous material media. As a significant example of the latter type (amongst other ones), it shall be completely worked out the problem of the a priori structure of linear viscous-stress tensor in a magnetoplasma. [Italian] Non e' facile, da parte del non-specialista, apprezzare pienamente il ruolo e l'importanza della Teoria degli Invarianti Classici nella storia della matematica (diciamo all'incirca tra il 1850 e il 1920). In questo studio, il lettore trova anzitutto una rassegna, succinta ma largamente improntata alla generalita', dei suoi fondamenti a partire da poche idee di base della teoria delle equazioni, oltre ad un breve inquadramento storico e alla illustrazione di un paio di esempi classici. Seguono poi alcune applicazion - presuntivamente nuove - alla fisica matematica, con particolare riferimento alle relazioni costitutive in mezzi materiali continui. Come significativo esempio di applicazione di quest'ultimo tipo, e' infine completamente sviluppato il calcolo della struttura a priori del tensore di viscosita' lineare in un magnetoplasma.

    Gamma-hydroxybutyrate (GHB) over the last two decades has generated increased notoriety as a euphoric and disinhibiting drug of abuse in cases of drug-related sexual assault and for this reason it is considered a 'date rape' drug. The first aim of this paper was to develop and fully validate a method for the detection of GHB in human hair by high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) after liquid-liquid extraction (LLE). The second aim was the application of the method to hair samples of 30 GHB-free users in order to determine the basal level. The results obtained showed no significant differences in endogenous concentrations (p = 0.556) between hair samples of the three groups (black, blonde, and dyed hair) and the age and sex of the subjects did not affect the endogenous levels. Another 12 healthy volunteers, with no previous history of GHB use, were selected and a single dose (25 mg/Kg) was orally administered to all of them and hair samples were collected before the administration of the single dose and other two samples were collected one month and two months later, respectively. The segmental analysis of the latter two samples allowed us to calculate two ratios: 4.45:1 (95% C.I. 3.52-5.63) and 3.35:1 (95% C.I. 2.14-5.18), respectively, which can be recommended as reasonable values for a positive identification of GHB intake. Finally the method was applied to three real cases where a GHB single exposure probably occurred. PMID:24947196

    This study discusses possibilities of using trigeneration in industrial power plant applications. The objective of this study is to compare trigeneration combined heat and power with compression chillers and separate production in terms of primary energy consumption and CO2 emissions. Some economic factors are also considered. The study focuses on the process industry, and two cases from different industrial sectors are presented. These sectors are food processing and mechanical pulp and paper. The results show that trigeneration can reduce emissions and operating costs compared with the separate production of heating and cooling. The amount of these savings is strongly dependent on the emission factor of the grid electricity replaced by trigeneration.

    The data provided by the International Monitoring system and the Products generated by the International data Center will be a unique source not only for CTBT verification but also for other activities. Although the utility of hydro acoustic and infrasonic data for such purposes is less obvious than that of seismic and radionuclide data, there are several possible applications for hazard and disaster warning purposes, and many potential long-term benefits for research and development. Such wider benefits from the monitoring system will best be realized through open international cooperation

    2013-01-01

    What kind of environment may exist on terrestrial planets around other stars? In spite of the lack of direct observations, it may not be premature to speculate on exoplanetary climates, for instance to optimize future telescopic observations, or to assess the probability of habitable worlds. To first order, climate primarily depends on 1) The atmospheric composition and the volatile inventory; 2) The incident stellar flux; 3) The tidal evolution of the planetary spin, which can notably lock a planet with a permanent night side. The atmospheric composition and mass depends on complex processes which are difficult to model: origins of volatile, atmospheric escape, geochemistry, photochemistry. We discuss physical constraints which can help us to speculate on the possible type of atmosphere, depending on the planet size, its final distance for its star and the star type. Assuming that the atmosphere is known, the possible climates can be explored using Global Climate Models analogous to the ones developed to sim...

Madrid 32 (1998, 59-84, physics/9702030] we will construct homogeneous spaces based on possible kinematical algebras and groups [Bacry H., Levy-Leblond J.-M., J. Math. Phys. 9 (1967, 1605-1614] and their contractions for 2-dimensional spacetimes. Our construction is different in that it is based on a generalized Clifford fibration: Following Penrose [Penrose R., Alfred A. Knopf, Inc., New York, 2005] we will call our fibration a Clifford fibration and not a Hopf fibration, as our fibration is a geometrical construction. The simple algebraic properties of the fibration describe the geometrical properties of the kinematical algebras and groups as well as the spacetimes that are derived from them. We develop an algebraic framework that handles all possible kinematic algebras save one, the static algebra.

    2005-05-01

    The term 'hypermachine' denotes any data processing device (theoretical or that can be implemented) capable of carrying out tasks that cannot be performed by a Turing machine. We present a possible quantum algorithm for a classically non-computable decision problem, Hilbert's tenth problem; more specifically, we present a possible hypercomputation model based on quantum computation. Our algorithm is inspired by the one proposed by Tien D. Kieu, but we have selected the infinite square well instead of the (one-dimensional) simple harmonic oscillator as the underlying physical system. Our model exploits the quantum adiabatic process and the characteristics of the representation of the dynamical Lie algebra su(1,1) associated to the infinite square well.

    2013-01-01

    We continue to study the problems of discovering new temporal and spatial properties of neutrinos from the point of the possible multi-dimensional extension the D=(3+1)- special theory of relativity. It is neutrino that can connect our Universe with new types of the matter, the new Universe. The possible discovery with neutrino new structure of the Time can confirm these ideas. However, the neutrino experiments aimed at new phenomena search can lead us to paradoxes related with the limits of applicability of the theory of relativity which demands special studies. This new phenomenon one can call by "Neutrino Paradoxes in Theories of Relativity". As examples of such paradoxes one can illustrate on the neutrino experiments MINOS,OPERA et al devoted to the measurements of neutrino velocity. As the interpretation of their results are model-dependent, by our opinion, the main goal of the observation a possible new time structure in these experiments is not reached. As the solutions to this problem it seems to us t...

  11. NET model coil test possibilities

    International Nuclear Information System (INIS)

    A single full size coil for NET/INTOR represents an investment of the order of 40 MUC (Million Unit Costs). Before such an amount of money or even more for the 16 TF coils is invested as much risks as possible must be eliminated by a comprehensive development programme. In the course of such a programme a coil technology verification test should finally prove the feasibility of NET/INTOR TF coils. This study report is almost exclusively dealing with such a verification test by model coil testing. These coils will be built out of two Nb3Sn-conductors based on two concepts already under development and investigation. Two possible coil arrangements are discussed: A cluster facility, where two model coils out of the two Nb3TF-conductors are used, and the already tested LCT-coils producing a background field. A solenoid arrangement, where in addition to the two TF model coils another model coil out of a PF-conductor for the central PF-coils of NET/INTOR is used instead of LCT background coils. Technical advantages and disadvantages are worked out in order to compare and judge both facilities. Costs estimates and the time schedules broaden the base for a decision about the realisation of such a facility. (orig.)

    Fluctuations in the spatial position of a probe particle that is driven far from equilibrium can provide valuable information about the driving force. Analysis of the position fluctuation is through the fluctuation theorem (FT) and a generalized detailed balance called Bier-Astumian relation (BA). Here we show the usefulness of the BA for mapping potential landscapes of a particle confined in a potential field. We also demonstrate how the FT can be used to extract the driving force for a particle driven by a constant force.

    International Nuclear Information System (INIS)

    Waste heat from nuclear power sources is classified in four categories, viz.: heat of cooling water 25-43 degC warm, low-potential heat obtained by afterheating to 50-60 degC, heat of hot water piping (130-200 degC), and heat of steam piping (205 degC). The former two categories will be used for heating greenhouses, for watering and sprinkling, intensifying fish breeding, growing algae, heating animal shelters, etc. The latter two categories will be used for drying and for food industry purposes.

    Various nanoparticles play a prominent role in modern biosciences and medicine. Especially fluorescent cellular biomarkers are a prospective material for diagnostics and therapy. Nevertheless, most of the available biomarkers have some drawbacks due to either physical and optical or cytotoxic properties. Here we investigated the potential of green fluorescent nanodiamonds as extra- and intracellular biomarkers for living cells. We characterized the structure of the used detonation synthesized nanodiamonds (DND) by X-ray diffraction (XRD) and the optical properties by fluorescence and infrared spectroscopy. For the extracellular attachment the nanodiamonds were functionalized by attaching antibodies that target extracellular structures such as membrane. Transfections were mediated by dendrimers, cationic liposomes and protamine sulfate. Using fluorescence microscopy, we confirmed successful extracellular binding on and transfection of the nanodiamonds into prostate cancer cells. Furthermore, nanodiamonds can be targeted selectively to intracellular structures. Therefore, nanodiamonds are a promising tool for biosensing.

    3D printing is a rapidly emerging additive manufacturing technology which can offer cost efficiency and flexibility in product development and production. In textile production 3D printing can also serve as an add-on process to apply 3D structures on textiles. In this study the low-cost fused deposition modeling (FDM) technique was applied using different thermoplastic printing materials available on the market with focus on flexible filaments such as thermoplastic elastomers (TPE) or Soft PLA. Since a good adhesion and stability of the 3D printed structures on textiles are essential, separation force and abrasion resistance tests were conducted with different kinds of printed woven fabrics demonstrating that a sufficient adhesion can be achieved. The main influencing factor can be attributed to the topography of the textile surface affected by the weave, roughness and hairiness offering formlocking connections followed by the wettability of the textile surface by the molten polymer, which depends on the textile surface energy and can be specifically controlled by washing (desizing), finishing or plasma treatment of the textile before the print. These basic adhesion mechanisms can also be considered crucial for 3D printing on knitwear.

    Full Text Available By applying a finger-printing method to the analysis of human milk oligosaccharides,several oligosacchartides were found to be deleted in the milk of non-secretor or Lewis negativeindividual. This finding afforded a clue to elucidate the enzymatic basis of blood typesin humans. Furthermore, disappearance of some major oligosaccharides led to the finding offive novel minor oligosaccharides, which were hidden under the major oligosaccharides.Later on, structures of more than seventy oligosaccharides were elucidated. These oligosaccharidesare derived from eleven core oligosaccharides by sialylation and/or fucosylation.All these oligosaccharides contain lactose at their reducing termini. This evidence, togetherwith the deletion phenomena found in the milk of two blood type individuals, suggested thatthe oligosaccharides are formed by the concerted action of glycosyltransferases, which areresponsible for formation of the sugar chains of glycoproteins on the surface of epithelialcells constructing the mucous membrane. The elongation may start by the action of iGnT.This enzyme is responsible for the addition of a β-N-acetylglucosamine residue to the C-3position of the galactose moiety constructing the N-acetyllactosamine group of the sugarchains of glycoconjugates. Therefore, oligosaccharides in human milk may include manystructures, starting from the N-acetyllactosamine residues in the sugar chains of various glycoproteins.Many evidences, which indicate that virulent enteric bacteria and viruses start theirinfection by binding to particular sugar chains of glycoconjugates on the surface of their targetcells, were presented recently. Therefore, milk oligosaccharides are expected to be usefulto inhibit the infection of these bacteria and viruses.

  6. Signal Morphing techniques and possible application to Higgs properties measurements

    Ecker, Katharina Maria; The ATLAS collaboration

    2016-01-01

    One way of describing deviations from the Standard Model is via Effective Field Theories or pseudo-observables, where higher order operators modify the couplings and the kinematics of the interaction of the Standard Model particles. Generating Monte Carlo events for every testable set of parameters for such a theory would require computing resources beyond the ones currently available in ATLAS. Up to now, Matrix-Element based reweighting techniques have been often used to model Beyond Standard Model process starting from Standard Model simulated events. In this talk, we review the advantages and the limitations of morphing techniques to construct continuous probability model for signal parameters, interpolating between a finite number of distributions obtained from the simulation chain. The technique will be exemplified by searching for deviations from the Standard Model predictions in Higgs properties measurements.

  11. Zirconium alloys for supercritical water reactor applications: Challenges and possibilities

    International Nuclear Information System (INIS)

    The corrosion behavior of model Zr-based alloys at 500 deg. C is assessed by long term (up to 400 days) corrosion testing in an effort to evaluate their potential for use in the supercritical water reactor and to assess the influence of alloying elements on corrosion behavior. The corrosion weight gains from such systematic testing are seen to be a factor of five higher than those measured at 360 deg. C but the protectiveness ranking of the alloys is similar. Detailed characterization of the oxide layers to rationalize the differences in corrosion behavior was performed using synchrotron radiation and systematic differences are observed in protective and non-protective oxides, especially near the oxide-metal interface. The overall corrosion rate of the best Zr-based alloys compared favorably with those of other alloys being considered for use in the supercritical water reactor

  12. Spontaneous ripple formation in phosphorene: electronic properties and possible applications

    2016-06-01

    According to the Mermin-Wagner theorem and theory of elasticity, long-range order in two-dimensional (2D) crystals will be inevitably destroyed due to a thermal fluctuation. Thus, a 2D lattice prefers a corrugation meaning that a 2D crystal is easy to present a ripple. In this work, we, via employing ab initio molecular dynamics (AIMD) simulations, for the first time evidenced that the inherent dynamics of phosphorene would lead to a spontaneous formation of ripples at room temperature. The height of a ripple closely associates with the temperature and the width. Via density functional theory (DFT) calculations, we further demonstrated that the emergence of ripples would remarkably reduce the bandgap of phosphorene. Via the construction of the unique phosphorene structure, we finally found that such a rippled structure is expected to be used in the light-emitting field. These results give us further knowledge of phosphorene, which goes beyond the current scope of phosphorene limited to the flat lattice.According to the Mermin-Wagner theorem and theory of elasticity, long-range order in two-dimensional (2D) crystals will be inevitably destroyed due to a thermal fluctuation.

    International Nuclear Information System (INIS)

    We have developed a Fresnel-type focusing device for cold neutrons fabricated using single crystals of magnesium fluoride. This stacked-lens device using 50 elements (with 50 beam-bending interfaces) demonstrated a focal length of 5 m with a good transmission of 0.829 for 1.14 nm neutrons. The focused beam was 5 times more intense than a beam of the same spot size with the same final flight path length produced with the traditional pinhole collimation. The background-scattering noise from lens was an order of magnitude larger than that of the traditional pinhole collimation in the momentum range of 0.01-0.05 nm-1, almost 10-3 of focused direct beam at the lowest momentum transfers measurable. This device produced an intensity gain in measured SANS data of more than 10 times when compared with the conventional pinhole geometry with the same minimum momentum transfer

    Optimization of transported proton beams through a pulsed solenoid in the laser proton experiment LIGHT at GSI has been studied numerically. TraceWin, SRIM and ATIMA codes were employed for this study with an initial distribution generated by MATLAB program fitted to Phelix measured data. Two individual tools have been used to produce protons beam as a later beam source: an aperture located at the solenoid focal spot as energy selection tool; and a scattering foil at a suitable position in the beam path that smoothens the simulated radial energy imprint on the beam profile. The simulation results show that the proton energy spectrum is filtered by the aperture and the radial energy correlation is smoothened.

  2. Possibility of ferromagnetic neutron matter

    CERN Document Server

    Hashimoto, Koji

    2014-01-01

    We study ferromagnetism at high density of neutrons in the QCD hadron phase, by using the simplest chiral effective model incorporating magnetic fields and the chiral anomaly. Under the assumption of spatial homogeneity, we calculate the energy density as a function of neutron density, with a magnetization and a neutral pion condensation a la Dautry and Neyman. We find that at a high density the energy of the ferromagnetic order is lower than that of the ordinary neutron matter, and the reduction effect is enhanced by the anomaly. Compared to the inhomogeneous phase with the alternating layer structure, our ferromagnetic phase turns out to be unfavored. However, once an axial vector meson condensation is taken into account in our simplest model, the ferromagnetic energy density is lowered significantly, which still leaves some room for a possible realization of a QCD ferromagnetic phase and ferromagnetic magnetars.

  4. Possible climates on terrestrial exoplanets.

    Forget, F; Leconte, J

    2014-04-28

    What kind of environment may exist on terrestrial planets around other stars? In spite of the lack of direct observations, it may not be premature to speculate on exoplanetary climates, for instance, to optimize future telescopic observations or to assess the probability of habitable worlds. To begin with, climate primarily depends on (i) the atmospheric composition and the volatile inventory; (ii) the incident stellar flux; and (iii) the tidal evolution of the planetary spin, which can notably lock a planet with a permanent night side. The atmospheric composition and mass depends on complex processes, which are difficult to model: origins of volatiles, atmospheric escape, geochemistry, photochemistry, etc. We discuss physical constraints, which can help us to speculate on the possible type of atmosphere, depending on the planet size, its final distance for its star and the star type. Assuming that the atmosphere is known, the possible climates can be explored using global climate models analogous to the ones developed to simulate the Earth as well as the other telluric atmospheres in the solar system. Our experience with Mars, Titan and Venus suggests that realistic climate simulators can be developed by combining components, such as a 'dynamical core', a radiative transfer solver, a parametrization of subgrid-scale turbulence and convection, a thermal ground model and a volatile phase change code. On this basis, we can aspire to build reliable climate predictors for exoplanets. However, whatever the accuracy of the models, predicting the actual climate regime on a specific planet will remain challenging because climate systems are affected by strong positive feedbacks. They can drive planets with very similar forcing and volatile inventory to completely different states. For instance, the coupling among temperature, volatile phase changes and radiative properties results in instabilities, such as runaway glaciations and runaway greenhouse effect. PMID:24664919

    The fast spread of laparoscopic surgery in the surgical community also required introduction of new methods of surgical education of these techniques. Training boxes applied for this reason meant a considerable help. The technique of the virtual reality introduced simulation, which is a new possibility in education. For the first time in the history of surgery we can measure medical students' or residents' dexterity and one can get acquainted with a surgical procedure in the form of "serious games". By application of the up-to-date imaging methods we can plan the movements of the surgeon's hand even before the planned operation, practice and repeating can contribute to the safety of the real procedure. Open surgical procedures can be practiced on plastic phantoms mimicking human anatomy and the use of interactive touch devices and e-learning can also contribute to practical education of surgery.

    2002-01-01

    It is known that superluminal transmission of information and energy contradicts Einstein's relativity. Here we announce an unusual TOE called 'nature theory' in which impossible things become possible. We present the scheme of an apparatus for sending signals over arbitrarily large distances with speeds arbitrarily exceeding the light speed in vacuum. Introducing the notions of effective speed and reliability of superluminal devices, we encourage experimenters to set and break world records in this new branch. At the same time we outline a mechanism (termed 'particle encapsulation') owing to which nature theory remains Lorentz invariant and so consistent with experiments. From among other numerous applications of nature theory we discuss briefly local antigravitation and new computing machines, called 'vacuum computers', applying 'cat principle'. They are of great interest because should enable humans to overcome the Goedel-Turing barrier.

Dimensioning using probabilistic fracture mechanics does not appear to be sensible in view of the existing uncertainties. These uncertainties are noticeable above all if components of high reliability are examined. In this case the ''tails'' of the distribution are mainly included in the calculation, i.e. the probability of failure is determined by extremely improbable values of parameters, whose frequency is estimated by extrapolation of existing data. This extrapolation naturally depends greatly on the special assumptions and model factors. However, it was found that probability calculations are useful in the context of studies of risks, where the remaining risk of a component is to be quantified and the effect of varying different parameters on the probability of failure is to be examined.

  8. Avalanche photodiodes now and possible developments

    International Nuclear Information System (INIS)

    Avalanche Photodiodes (APDs) are now out of their infancy and are used in large numbers in the electromagnetic calorimeter of CMS where they have to stand the extremely hostile environment of LHC. This type--with smaller sensitive area and arranged in monolithic arrays--is an excellent candidate for the read out of scintillating crystals in medical imaging and a PET scanner operates already successfully since more than 3 years. We present the properties of the device used in CMS and possible improvements of the structure, which could open the door for new applications. Operating APDs at low temperatures or in Geiger mode will allow single photon counting and in future they could replace photomultiplier tubes

    Kühnl-Kinel, J

    1999-01-01

    Optimum distribution of energy supply systems can result in large savings in industrial facilities and production devices. Identifying the configuration of existing equipment and its loading, in order to minimize total energy consumption and at the same time satisfy given load demands, has very high payback potential. This paper presents the principle of trigeneration, the technology that can offer a highly efficient way of converting primary fuel (gas, oil) into useful energy as electricity, heat and chilled water simultaneously. It explains different factors that must be considered for such systems to be economically feasible. Some examples of industrial trigeneration systems are analysed and discussed to illustrate the application. Also the possibility of implementation of trigeneration at CERN is discussed, taking into account the existing cogeneration system, power supply structure, secondary energy demands, as well as future developments in our energy policy.

  11. Possible pathomechanism of autoimmune hepatitis.

    Science.gov (United States)

    Prandota, Joseph

    2003-01-01

    The hepatotropic viruses, measles, and herpesviruses as well as different drugs were repeatedly shown to act presumably as a trigger in patients with autoimmune hepatitis (AI-H). On the other hand, it is known that viral infections stimulate interferon production, which inactivates the cytochrome P-450 enzymes involved in the metabolism of several endogenous substances and exogenous environmental agents. Moreover, it was reported that several cytokines, including interferons, as well as transforming growth factor beta1 and human hepatocyte growth factor, which are abundantly produced and released in the body during infections, also downregulated expression of major cytochrome P-450 and/or other biotransformation enzymes. It seems that all these factors, in addition to individual immune response and the nature and amount of the neoantigen(s) produced, impair the equilibrium of bioactivation and detoxication pathways, thus leading to the development of AI-H in a genetically predisposed person continually exposed to harmful environmental factor(s). Possible increased/decreased density of lysine residues at position D-related human leukocyte antigen locus (DR)beta71 of the antigen-binding groove may affect the eventual steroid-sparing effect of this critical amino acid at the cellular level. In addition, some food additives, such as monosodium glutamate (MSG) and/or aspartame regularly consumed in excessive amounts, may eventually disturb the delicate balance between a positively charged amino acid residue at position DRbeta71 (lysine or arginine) and a negatively charged amino acid residue at position P4 on the antigenic peptide (glutamic acid or aspartic acid). This may favor formation of a salt bridge between these amino acid residues within the hypervariable region 3 on the alpha-helix of the DRbeta polypeptide and facilitate autoantigen presentation and CD4 T-helper cell activation. MSG and aspartate may also depress serum concentrations of growth hormone, which

  12. Possibilities of Engineering Ethics Education

    Science.gov (United States)

    Matsuki, Junya

    This paper discusses the possibilities of teaching engineering ethics in universities. This is based on the teaching experience of a newly developed course that has been introduced to the Department of Electrical and Electronic Engineering at the University of Fukui, since April 2004. Entitled “ethics for engineers”, the course targeted senior-level students and makes use of a newly written textbook that emphasizes social aspects of science and technology. To encourage students to think and form their own opinions with regards to their role as engineers in a modern technological society, the book is complemented by other materials such as videos, newspaper articles and some other relevant books. Students are also encouraged to write reports that reflect their own opinion on subjects such as what kind of engineers they intend to be, or what do ethics mean to them? The paper will conclude by giving a course evaluation including students' response, highlighting valuable experiences and stating the importance of further developing this topic in engineering education.

  13. Uncertainty Relations and Possible Experience

    Directory of Open Access Journals (Sweden)

    Gregg Jaeger

    2016-06-01

    Full Text Available The uncertainty principle can be understood as a condition of joint indeterminacy of classes of properties in quantum theory. The mathematical expressions most closely associated with this principle have been the uncertainty relations, various inequalities exemplified by the well known expression regarding position and momentum introduced by Heisenberg. Here, recent work involving a new sort of “logical” indeterminacy principle and associated relations introduced by Pitowsky, expressable directly in terms of probabilities of outcomes of measurements of sharp quantum observables, is reviewed and its quantum nature is discussed. These novel relations are derivable from Boolean “conditions of possible experience” of the quantum realm and have been considered both as fundamentally logical and as fundamentally geometrical. This work focuses on the relationship of indeterminacy to the propositions regarding the values of discrete, sharp observables of quantum systems. Here, reasons for favoring each of these two positions are considered. Finally, with an eye toward future research related to indeterminacy relations, further novel approaches grounded in category theory and intended to capture and reconceptualize the complementarity characteristics of quantum propositions are discussed in relation to the former.

    2014-07-01

    Full Text Available New possible ways of plastics manufacture and waste treatment are being searched when trying to tackle the problems related to the growth of waste quantities and decline in non-renewable resources. Presently, the most promising and effective way to solve the mentioned problems is production of bioplastics, but its way to recognition is very slow. One of the barriers is the absence of clear and united opinion throughout the EU Arising new discussions about biodegradable and biobased plastics will allow responsible authorities to update and adapt the legal law, which now almost does not include any reglement on bioplastics production and usage. The other issues of bioplastics are social aspects as this material can be made of primal food sources like crops, and the ecological ones because of their unknown effects on human health and the environment. Nevertheless, the main problem remains the same - the price of petro-plastics is still lower than that of bioplastics. Despite this, the biggest companies of the world are starting an initiative to manufacture this new kind of plastics and to widen the range of bioplastics usage in packaging. Considering today’s situation and tendencies, at the end of this paper the recommendations for the improvement and speeding up of the processes related to bioplastics manufacture, usage and its waste management in Europe and Lithuania are presented.

    Russo, Andrea; Urlić, Ivan; Kasum, Josip

    2015-09-01

    Forensics (forensic--before the Forum) means the application of knowledge from different scientific fields in order to define facts in judicial and/or administrative procedures. Nowadays forensics, besides this, finds its application even in different economic processes. For example, forensics enters the commercial areas of business intelligence and of different security areas. The European Commission recognized the importance of forensics, and underscored the importance of development of its scientific infrastructure in member States. We are witnessing the rise of various tragedies in economic and other kinds of processes. Undoubtedly, the world is increasingly exposed to various forms of threats whose occurrences regularly involve people. In this paper we are proposing the development of a new approach in the forensic assessment of the state of human resources. We are suggesting that in the focus should be the forensic approach in the psychological assessment of awareness of the individual and of the critical infrastructure sector operator (CISO) in determining the level of actual practical, rather than formal knowledge of an individual in a particular field of expertise, or in a specific scientific field, and possible forensic meanings.

  16. Coating possibilities for magnetic switches

    International Nuclear Information System (INIS)

    High average power magnetic pulse compression systems are now being considered for use in several applications such as the High Power Radiation Source (HiPoRS) project. Such systems will require high reliability magnetic switches (saturable inductors) that are very efficient and have long lifetimes. One of the weakest components in magnetic switches is their interlaminar insulation. Considerations related to dielectric breakdown, thermal management of compact designs, and economical approaches for achieving these needs must be addressed. Various dielectric insulation and coating materials have been applied to Metglas foil in an attempt to solve the complex technical and practical problems associated with large magnetic switch structures. This work reports various needs, studies, results, and proposals in selecting and evaluating continuous coating approaches for magnetic foil. Techniques such as electrophoretic polymer deposition and surface chemical oxidation are discussed. We also propose continuous photofabrication processes for applying dielectric ribs or spacers to the foil which permit circulation of dielectric liquids for cooling during repetitive operation. 10 refs., 8 figs., 11 tabs

  17. How Does Moxibustion Possibly Work?

    Jen-Hwey Chiu

    2013-01-01

    Full Text Available “Acupmoxa” is a hybrid word of “acupuncture” and “moxibustion” that more closely resembles the Chinese ideograph for this treatment. People in Western countries are more familiar with acupuncture, while moxibustion is less popular, partially due to the paucity of scientific studies. Although the evidence-based efficacy of moxibustion needs to be further clarified, the mechanisms by which moxibustion may work include temperature-related and nontemperature-related ones. Local somatothermal stimulation (LSTS, one type of moxibustion, is achieved by application of a heat source to and above the acupoint. Such mild heat stimulation of the acupoint induces little skin damage, in contrast to the burning effect of moxibustion, but does provoke mild oxidative stress in the viscera. Thus, preconditioned LSTS at the peripheral acupoints LR 14 and PC 6 of animals is able to induce visceral HSP70 expression and to protect the liver and the heart against ischemia-reperfusion injury. Nontemperature-related mechanisms include smoke, herbs, and biophysical (far infrared stimulation. We conclude that LSTS, a remote preconditioning method, has potential clinical usefulness. However, evidence-based efficacy and safety studies involving large-scaled clinical trials are needed in order that this approach will pass muster with Western scientists.

    Full Text Available Primary receptacles improve profitability legumes are limiting demonstrations and acts of plant diseases and pests. Pathogens are 25-50% lower yield of soybean, chickpea, beans, peas. Pests focally up to 87% of viable seeds sown reduce the number of plants per 1 ha. Only effective protection against disease and estimates of crop production can increase the average profitability of legume crops by 15-30%. Livestock is very important, but in the Southern Urals requires real support for its production with a positive balance (in the calculations with a deviation of 5%. The most important resource in our opinion may be a reduction in price of fodder. Thus, legumes are sought for animal protein. Soybeans, chickpeas, beans, peas universal culture and the possibility of their use in the food balance for a healthy diet of ordinary people engaged in recreational and other sports niche expands further improve the profitability of their production. Regulation of the balance of the distribution of food and feed produced grain legumes allows fine regulation of the cost of fodder for a particular type of livestock activities. Phytosanitary capabilities , the balance of influence of legumes on arable land, also requires a fine regulation of these processes. Obtaining long-term public support for this production is unlikely in the WTO because actual search for ways to improve the profitability of production of agricultural technologies. In our view, a comprehensive approach taking into account the capacity of local markets for crop production. Such activity can act as a guaranteed quality of agro-technology and animal products from local resources specific zonal conditions of production.

  19. Possible refurbishment of Point Lepreau

    International Nuclear Information System (INIS)

    In February 2000, the NB Power Board of Directors approved Phase one of a project to produce a business case including a detailed scope and estimate associated with the possible refurbishment of the Point Lepreau Generating Station (PLGS). The Preliminary plan for refurbishment projects an 18-month outage starting as early as the spring of 2006. If the station were to be refurbished, then it would be run for another 25 to 30 years. The decision on whether or not to refurbish PLGS has not been made and is not expected until the summer of 2002. The results of the first phase of the project will be used to prepare a detailed business case that will be presented to the NB Power board of directors in January of 2002. At that time a decision will be made as to whether to refurbish the unit, or obtain other means of replacing the energy produced by PLGS. The station currently produces about a third of the power generated within the province. If the business case is approved, all-380 Pressure Tubes and Calandria Tubes, along with their related End Fittings and Feeders would be replaced. This material would be stored in new storage vaults to be constructed at the existing on-site Waste Management Facility. Replacement of other station components will be performed as required, as determined from the results of a comprehensive Plant Condition Assessment. The condition assessments build on work done under the Plant Life Management Program. Point Lepreau Generating Station has operated well since start of commercial operation in early 1983. With a lifetime capacity factor of about 84% (up to the end of 2000), it has proven to be an economic and environmentally sound electricity provider. The station has also had a significant positive economic impact in Southern New Brunswick, employing over 600 people. However the Pressure Tubes and Feeders are nearing the point in time in which they will exceed their fitness for service criteria. Although tubes can be replaced on an

By using CST in the design and operation of future structures systems, engineers will have a better understanding of how a system responds and lasts, more cost-effective methods of designing and testing models, and improved productivity. For informational and educational purposes, a videotape is being produced using both static and dynamic images from research institutions, software and hardware companies, private individuals, and historical photographs and drawings. The extensive number of CST resources indicates its widespread use. Applications run the gamut from simpler university-simulated problems to those requiring solutions on supercomputers. In some cases, an image or an animation will be mapped onto the actual structure to show the relevance of the computer model to the structure.

    International Nuclear Information System (INIS)

    More locations and building material will be needed to solve the housing needs, actually the future quantities will equal the total of all the previous building. And presently one quarter of the world population is already homeless. The development of human civilization in the new technological era goes on extremely quickly. In the search for new spaces, in the last decade of the 20th century, in town renovation planning the application of subterranean civil engineering is very popular. Below ground level, the new towns are built with many stories, with exclusively artificial light and artificial climate. There is not the slightest possibility of natural ventilation. These spaces have not been investigated as regards the contents of radon. Man is not adapted to spend most of the time in under artificial conditions. It is still to be discovered how it will affect humans and what is the degree of exposure to ionizing radiation in such conditions. It might be better to abandon underground construction before the adverse effects are proved. Previous mistakes in building must be overcome and new technologies applied as well as sustainable development in the future. (author)

    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.

    Exploiting heat by incorporating heat exchanger pipes into tunnel linings has been recently proposed. This paper investigates this topic by studying a possible application for a new metro line currently under design. The Dudullu-Bostanci line, planned to be excavated in the Turkish city of Istanbul is considered. The heat exchange potential for the tunnel is evaluated, together with the environmental and economical impacts

  6. Characterization and possible uses of ashes from wastewater treatment plants

    International Nuclear Information System (INIS)

    This work, on the ashes from the wastewater treatment plant of Galindo (Vizcaya, Spain), has been outlined with the purpose of finding their physico-chemical properties and suggesting possible applications. Ashes contain important quantities of iron, calcium, silica, alumina and phosphates. X-Ray diffraction data make it possible to estimate the mineralogical compositions of the original ashes and also, after thermal treatment at 1200 and 1300 deg. C, the main reactions occurring in thermal treatment. Particle size analysis makes it possible to classify ashes as a very fine powdered material. The thermal treatment leads to a densification of the material and provokes losses of weight mainly due to the elimination of water, carbon dioxide and sulphur trioxide. Application tests show that ashes are not suitable for landfill and similar applications, because of their plastic properties. Testing for pozzolanic character, after the ashes had been heated at 1200 deg. C, did not lead to a strong material probably due to low contents in silica and alumina or to requiring a higher heating temperature. Thermal treatment leads to densification of the material with a considerable increase of compressive strength of the probes. The use of additives (clays and powdered glass) to improve ceramic properties of ashes will be the aim of a future work

  7. POSSIBILITY AND EVIDENCE-BASED RELIABILITY ANALYSIS AND DESIGN OPTIMIZATION

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Engineering design under uncertainty has gained considerable attention in recent years. A great multitude of new design optimization methodologies and reliability analysis approaches are put forth with the aim of accommodating various uncertainties. Uncertainties in practical engineering applications are commonly classified into two categories, i.e., aleatory uncertainty and epistemic uncertainty. Aleatory uncertainty arises because of unpredictable variation in the performance and processes of systems, it is irreducible even adding more data or knowledge. On the other hand, epistemic uncertainty stems from lack of knowledge of the system due to limited data, measurement limitations, or simplified approximations in modeling system behavior and it can be reduced by obtaining more data or knowledge. More specifically, aleatory uncertainty is naturally represented by a statistical distribution and its associated parameters can be characterized by sufficient data. If, however, the data is limited and can be quantified in a statistical sense, epistemic uncertainty can be considered as an alternative tool in such a situation. Of the several optional treatments for epistemic uncertainty, possibility theory and evidence theory have proved to be the most computationally efficient and stable for reliability analysis and engineering design optimization. This study first attempts to provide a better understanding of uncertainty in engineering design by giving a comprehensive overview of its classifications, theories and design considerations. Then a review is conducted of general topics such as the foundations and applications of possibility theory and evidence theory. This overview includes the most recent results from theoretical research, computational developments and performance improvement of possibility theory and evidence theory with an emphasis on revealing the capability and characteristics of quantifying uncertainty from different perspectives

  10. Two novel possibilities in Higgs phenomenology

    OpenAIRE

    We discuss two novel possibilities in Higgs physics. The first is that, by adding a real Higgs triplet to the Standard Model, it is possible for the lightest Higgs boson to be as heavy as 500 GeV without any fine tuning. The second, somewhat orthogonal, possibility concerns the MSSM with explicit CP violation. This model is known to permit a light Higgs boson with mass below 50 GeV which may have avoided detection at LEP and may also avoid detection at the Tevatron and LHC. We suggest that di...

  20. Possible approaches to rapid control of IFE targets

    International Nuclear Information System (INIS)

    The goal of ICF microobjects characterization (such as polymer and glass shells, and cryogenic targets) is to provide reliable information within a definite time. From this viewpoint, the following two stages of producing the targets are of special interest: i. fuel layering technique development, which requires the most comprehensive information on the object (i.e. a 3D reconstruction of the microobject), ii. the fueling of a commercial power plant, requiring 500, 000 fusion targets each day or six fusion targets each second (i.e., this determine the values of some target parameters by which the target can be rejected during its injection). In this report we consider possible approaches exclusively meant for threshold target characterization, namely the application of algorithms for target characterization, based on low-projected tomography, and the application of methods of coherent optics based on Fourier holography for ultra-rapid target characterization. The results of computer experiments are presented. It is shown that (a) depending on the choice of rejection rule, it is possible to construct different threshold algorithms with different operational speeds, and (b) in the case of target quality control using holography method of image recognition, the operational time can be as short as ∼1 μs. Therefore, target characterization during the injection process is possible. (author)

  3. EM 12 a possible fast reactor core material

    International Nuclear Information System (INIS)

    The advantages of this class of steel are well known, essentially suppression of swelling and of irradiation embrittlement at high temperature. EM 12, a potential steam generator materials, is currently under evaluation in CEA for use as wrapper and possibly cladding material. Preliminary irradiation experiments up to 82 dpaF at 6000C and up to 157 dpaF at 400-4400C have been made. They give some indication of the swelling to be expected, of the irradiation creep, of the effect of irradiation on the room temperature tensile properties and on the ductile to brittle transition behavior. Other aspects of the use of ferritic steels such as compatibility with sodium and reprocessing are raised. The conclusion is that EM 12, although not the best possible choice for this application typifies the behavior of a large class of potential materials

  4. Possibilities for the prevention of cancer

    International Nuclear Information System (INIS)

    Two types of evidence suggest that the prevention of cancer is a practical possibility: first, our increasing knowledge of the causes of cancer, many of which can be avoided without difficulty, and second, evidence that all common cancers whose causes are still unknown vary in incidence with place, time or social group. Many known causes still exist, however, and are responsible for hundreds of thousands of cases annually throughout the world. Practical possibilities for prevention now and in the near future include changes in personal habits (tobacco, alcohol, diet), control of exposure to known cancer-producing substances (carcinogens) in both industry and the general environment, and immunization against viruses causing cancer.

    Kapovits, I.; Nagyvary, J.

    1978-01-01

    The two types of thiophosphate reactivities were studied in a system that involves reactions of 5'-substituted adenosine derivatives. In this system, both nucleophilic displacement on carbon and P-S cleavage are possible. The products and possible mechanisms of cyclization experiments involving different leaving groups are reported. The data indicate superior reactivity of the 3'-OH of the ribonucleoside, although in most other systems the 2'-OH is found to show superior reactivity. It is suggested that thiophosphates might play a role in prebiotic activation and phosphorylation reactions.

  7. Possibilities of implementing bimetallic hammer castings in crushing industries

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available For decades manganese steel casts have been most used materials for manufacturing elements subjected to impact and high stress abrasion. These materials are used in countless industrial applications that involve crushing of raw material by impact. Some of most important characteristics of manganese cast steels are work-hardening and high strength. Opposite from manganese steels, highly alloyed white cast irons are materials with high amount of hard carbide phases that shows better abrasion resistance but have lower strength and impact energy. Aim of this paper is to investigate possibilities to reduce costs and maintenance periods by implementing bimetallic materials.

    Reading comprehension (RC) is below the international standard in many countries of Latin America (LA). Here we review factors that might be associated with failure in RC of the first language in LA. Then we present interventions reporting beneficial impact on RC in typically developing students from English-speaking countries and discuss their possible applicability in LA. We conclude that research-based pedagogical interventions are currently available to promote RC at school and may be suitable to implement in LA in order to improve RC. PMID:27254828

    Objective To investigate the application of the Murex HCV Ag/Ab combination (version 4.0) assay for blood screening. Methods 987 HCV-Ab reactive and gray zone samples were collected from routine blood screening and detected by both the Murex HCV Ag/Ab combination assay and Murex HCV Ab reagent. And verification test were carried out by RIBA and HCV NAT test. Results The positive rate of Murex HCV Ag/Ab combination assay and the Murex HCV Ab assay was 73.3% and 75.4% respectively, the negative rate was 95.8% and 90.8% and the final total positive rate was 85.8% and 84.0% respectively. The positive compliance rate between Murex HCV Ag/Ab combination and Murex HCV Ab assay was 76.7%, the negative compliance rate was is 94.5% and the total compliance rate was 87.6%. Among 123 inconsistent samples, 5 were RIBA negative /RNA positive,Murex HCV Ag/Ab positive for 4 samples (including confirmed window period sample); Murex HCV Ab was positive in only one sample; for 15 RIBA positive and RNA negative samples, 5 samples were positive by Murex HCV Ag/Ab and 10 samples were positive by Murex HCV Ab. Conclusions The RIBA negative and RNA positive samples could be efficiently detected out by Murex HCV Ag/Ab combination assay. Because the low compliance rate between Murex HCV Ag/Ab combination and Murex HCV Ab assay and the low detection rate of both system, we recommend the conjunction application of Murex HCV Ag/Ab combination and the Murex HCV Ab assay for blood screening. The double -check for HCV EIA blood screening strategy can help to reduce the possibility of transfusion transmitted infectious diseases.%目的 探讨第4代Murex HCV Ag/Ab联合检测试剂在血液筛查中的应用价值.方法 应用Murex HCV Ag/Ab联合检测试剂与Murex HCV Ab检测试剂,对987份血液筛查中HCV抗体初筛阳性和灰区标本及1份确认窗口期标本进行比较检测,应用RIBA、病毒核酸检测试剂进行补充验证实验,并对结

  6. The simplest possible bouncing quantum cosmological model

    CERN Document Server

    Peter, Patrick

    2016-01-01

    We present and expand the simplest possible quantum cosmological model already discussed in a previous work: the trajectory formulation of quantum mechanics applied to cosmology in the FLRW minisuperspace without spatial curvature. The initial conditions that were assumed there were such that the wave function would not change its functional form but instead provide a dynamics to its parameters. Here, we consider a more general situation, in practice consisting of modified Gaussian wave functions, aiming at obtaining a bounce from a contracting phase. Whereas previous works consistently obtain very symmetric bounces, we find that it is possible to produce highly non symmetric solutions, and even cases for which multiple bounces naturally occur. We also introduce a means of treating the shear in this category of models by quantizing in the Bianchi I minisuperpace.

  7. How is an absolute democracy possible?

    Directory of Open Access Journals (Sweden)

    Joanna Bednarek

    2011-01-01

    Full Text Available In the last part of the Empire trilogy, Commonwealth, Negri and Hardt ask about the possibility of the self-governance of the multitude. When answering, they argue that absolute democracy, understood as the political articulation of the multitude that does not entail its unification (construction of the people is possible. As Negri states, this way of thinking about political articulation is rooted in the tradition of democratic materialism and constitutes the alternative to the dominant current of modern political philosophy that identifies political power with sovereignty. The multitude organizes itself politically by means of the constitutive power, identical with the ontological creativity or productivity of the multitude. To state the problem of political organization means to state the problem of class composition: political democracy is at the same time economic democracy.

    Schnyder, U W

    1983-01-01

    Several years ago the therapeutic possibilities for the treatment of inherited skin disorders were rather restricted; recently new possibilities have been developed and successfully applied. The author discusses the indications for a surgical procedure in basal cell nevus syndrome and the satisfying results revealed by dermabrasion in sebaceous adenoma of Pringle. The use of a low phenylalanine and tyrosine diet in case of palmoplantar keratosis with tyrosinemia is of theoretical as well as practical interest. However, a most striking therapeutic success is obtained by the treatment with drugs. The substitution of zinc in acrodermatitis enteropathica is very effective and not expensive! The positive effect of phenytoin in epidermolysis bullosa cicatricans is based on the partial inhibition of collagenase activity by this drug. Finally the author discusses the advantages of a treatment with retinoids in different hereditary keratinization disorders. PMID:6666938

    Numerous health risks have been identified in dwellings and are a public health priority. Homes most often accumulate several different risks. Intervention programs must take this reality into account. Identification of a source of chemical pollution in the home makes it possible to correct indoor air quality quickly and inexpensively and provides immediate health benefits. Extermination of mites requires implementation of a group of complementary techniques in all contaminated areas, with help, when possible, from an indoor environment counselor. A team of multidisciplinary indoor habitat and health advisors must assess the health risks of the home. This inexpensive strategy reduces risks, although its effectiveness still requires confirmation. When the building has structural defects or abnormalities, more complex methods of renovation, or even moving, are necessary. There again, a complete assessment of their benefits to occupants' health is necessary. PMID:17433612

  11. Possibilities of conventional intravenous subtraction angiography (ISA)

    Energy Technology Data Exchange (ETDEWEB)

    1984-01-01

    Based on the experiences collected with 127 patients, the pros and cons as well as the indications for intravenous angiography with conventional photographic subtraction technique (ISA) are discussed in comparison with rival procedures. ISA can be performed in every angiography unit without any additional investment, and its possibilities of use are identical with those of the DSA. As a matter of fact, it is a simple and safe method for visualising the renal arteries in the course of intravenous urography in the diagnostic evaluation of hypertansion. For the first time, it has become possible to perform transvenous determination of the complete status of the arteries of the pelvis and legs, using a new technical system (simultaneous use of two film changers in the frontal plane - ISA aortoarteriography).

    Full Text Available The aim of the article. The aim of the article is to offer the method of estimation of region transport clusterization possibilities. The results of the analysis. The row of indexes is offered for the possibilities estimation of region transport clusterization: coefficient of transport industry localization on the territory of region; coefficients of territorial transit; coefficients of an interregional transport specialization; coefficient of transportation volumes on one inhabitant of the region. For realization of calculations data there is a need to take on the average for 5-6 last years. Than the nearer got values of coefficients are to unit, the probability of a region transport clusterization is higher. The results of calculation of a transport industry localization coefficient on the territory of Zaporizhzhya area testify to high enough degree of transport industry localization on the region territory. The values of territory transit coefficients also testify to high transit possibilities of Zaporizhzhya region territory, which are used incompletely. The coefficient of an interregional transport specialization allows, at first, to analyse the change of every type of region transport ponderability in the scales of country during the certain period of time; secondly, to define the type of transport, which conducts in a region. The expected coefficients of a transport specialization specify on the advantage of motor and river transport. In addition, the part of motor transport did not almost change during the investigated period, while the coefficient of a transport specialization of Zaporizhzhya region on an aviation transport diminished substantially. According to calculations the final coefficient of region transport clusterization potential estimation specifies on high enough possibilities of transport cluster creation in the Zaporizhzhya region. Therefore the possibility of interregional transport cluster creation is considered, the

    Full Text Available Background: Bevacizumab a recombinant humanized monoclonal antibody was approved in 2004 by US FDA for metastatic colorectal cancer. It is reported to cause potentially serious toxicities including severe hypertension, proteinuria, and congestive heart failure. Aim: To correlate adverse event tetany with the use of bevacizumab. Materials and Methods : World Health Organization′s Uppsala Monitoring Centre, Sweden, for reporting of adverse drug reactions from all over the world, identified 7 cases with tetany-related symptoms to bevacizumab from four different countries. These 7 patients reported to UMC database developed adverse events described as musculoskeletal stiffness (1, muscle spasm (1, muscle cramps (1, lock jaw or jaw stiffness (4, and hypertonia (1, with hypocalcaemia. Results: After detailed study of the possible mechanism of actions of bevacizumab and factors causing tetany, it is proposed that there is a possibility of tetany by bevacizumab, which may occur by interfering with calcium metabolism. Resorption of bone through osteoclasts by affecting VEGF may interfere with calcium metabolism. Another possibility of tetany may be due to associated hypomagnesaemia, hypokalemia, or hyponatremia. Conclusions: Tetany should be considered as a one of the signs. Patient on bevacizumab should carefully watch for tetany-related symptoms and calcium and magnesium levels for their safety.

    Full Text Available This article presents a study of processes supporting student learning possibilities in digital workshops planned and held at art museums in Denmark. The investigation aims to provide insights into factors enhancing learning possibilities, including the educator’s dialogic performance, experiences of art, and perceived qualities of digital content creation processes in art museum education workshops. To address the research question of what conditional and processual factors can be said to support learning possibilities, a model was developed on the basis of fieldwork and theories of media education, art pedagogy and motivation. The model was then analyzed using structural equation modelling (SEM on data collected (N= 502 after workshops in two museums. The results suggest that the dialogic performance of museum educators, a positive art experience and positive perceptions of working with digital media are factors that strongly support student participation and reflection – although to various degrees. The findings also show that, in cases in which students are disinterested and see little value in participating during the workshop, this amotivation is likely to be lower when their art experiences and their perceptions of the media production process are positive.

    1974-01-01

    The possibilities of life on Jupiter are discussed from the point view of life as known on earth. That is, it is assumed that any life on Jupiter would not involve new principles foreign to us. Proteins would be a constituent as would fats and the other building blocks of living organisms on earth. This leads to a set of limiting parameters, such as pressure. Studies in the laboratory have shown that proteins and other essential molecules are denatured by pressures of 4000 atm and higher. Thus, life cannot be expected to exist in the great depths of the Jovian atmosphere. It could exist only at depths of several hundred kilometers in the atmosphere. Since no solid surface could possibly exist at such altitudes, any organisms present must be small enough to be buoyed up by the turbulent atmospheric currents or must fly or both. Such possibilities, however, seem to be real. The necessary nutrients to preserve life and foster growth could be furnished by the Miller-Urey type reactions of ionizing radiation on the reducing atmosphere undoubtedly present.

    The working memory plays an important role in successfully overcoming adverse listening conditions and should consequently be considered when designing and testing hearing aids. A number of studies have established the relationship between hearing in noise and working memory involvement, but with the Sentence-final Word Identification and Recall (SWIRL) test, it is possible to show that working memory is also involved in listening under favorable conditions and that noise reduction has a positive influence in situation with very little noise. Although the capacity of the working memory is a finite individual size, its involvement can differ with fatigue and other factors and individualization of hearing aids should take this into account to obtain the best performance. A way of individually adapting hearing aids is based on changes in the electrical activity of the brain (EEG). Here we present the possibilities that arise from using EEG and show that ear-mounted electrodes is able to record useful EEG that can be explored for individualization of hearing aids. Such an adaptation could be done based on changes in the electrical activity of the brain (EEG). Here we present the possibilities that arise from using EEG and show that ear-mounted electrodes is able to record useful EEG that can be explored for individualization of hearing aids.

    Word order evolution has been hypothesized to be constrained by a word order permutation ring: transitions involving orders that are closer in the permutation ring are more likely. The hypothesis can be seen as a particular case of Kauffman's adjacent possible in word order evolution. Here we consider the problem of the association of the six possible orders of S, V and O to yield a couple of primary alternating orders as a window to word order evolution. We evaluate the suitability of various competing hypotheses to predict one member of the couple from the other with the help of information theoretic model selection. Our ensemble of models includes a six-way model that is based on the word order permutation ring (Kauffman's adjacent possible) and another model based on the dual two-way of standard typology, that reduces word order to basic orders preferences (e.g., a preference for SV over VS and another for SO over OS). Our analysis indicates that the permutation ring yields the best model when favoring pa...

    In the last few years, Unmanned Aircraft Systems (UAS) have become more important and its use for different application is appreciated. At the beginning UAS were used for military purposes. These successful applications initiated interest among researchers to find uses of UAS for civilian purposes, as they are alternative to both manned and satellite systems in acquiring high-resolution remote sensing data at lower cost while long flight duration. As UAS are built from many components such as unmanned aerial vehicle (UAV), sensing payloads, communication systems, ground control stations, recovery and launch equipment, and supporting equipment, knowledge about its functionality and characteristics is crucial for missions. Therefore, finding appropriate configuration of all elements to fulfill requirements of the mission is a very difficult, yet important task. UAS may be used in various maritime applications such as ship detection, red tide detection and monitoring, border patrol, tracking of pollution at sea and hurricane monitoring just to mention few. One of the greatest advantages of UAV is their ability to fly over dangerous and hazardous areas, where sending manned aircraft could be risky for a crew. In this article brief description of aerial unmanned system components is introduced. Firstly characteristics of unmanned aerial vehicles are presented, it continues with introducing inertial navigation system, communication systems, sensing payloads, ground control stations, and ground and recovery equipment. Next part introduces some examples of UAS for maritime applications. This is followed by suggestions of key indicators which should be taken into consideration while choosing UAS. Last part talks about configuration schemes of UAVs and sensor payloads suggested for some maritime applications.

  6. The impact of possible climate catastrophes on global warming policy

    International Nuclear Information System (INIS)

    Recent studies on global warming have introduced the inherent uncertainties associated with the costs and benefits of climate policies and have often shown that abatement policies are likely to be less aggressive or postponed in comparison to those resulting from traditional cost-benefit analyses (CBA). Yet, those studies have failed to include the possibility of sudden climate catastrophes. The aim of this paper is to account simultaneously for possible continuous and discrete damages resulting from global warming, and to analyse their implications on the optimal path of abatement policies. Our approach is related to the new literature on investment under uncertainty, and relies on some recent developments of the real option in which we incorporated negative jumps (climate catastrophes) in the stochastic process corresponding to the net benefits associated with the abatement policies. The impacts of continuous and discrete climatic risks can therefore be considered separately. Our numerical applications lead to two main conclusions: (i) gradual, continuous uncertainty in the global warming process is likely to delay the adoption of abatement policies as found in previous studies, with respect to the standard CBA; however (ii) the possibility of climate catastrophes accelerates the implementation of these policies as their net discounted benefits increase significantly

    2010-01-01

    Biosurfactants are a group of microbial molecules identified by their unique capabilities to interact with hydrocarbons. Emulsification and de-emulsification, dispersion, foaming, wetting and coating are some of the numerous surface activities that biosurfactants can achieve when applied within systems such as immiscible liquid/liquid (e.g., oil/water), solid/ liquid (e.g., rock/oil and rock/water) and gas/liquid. Therefore, the possibilities of exploiting these bioproducts in oil-related sciences are vast and made petroleum industry their largest possible market at present. The role of biosurfactants in enhancing oil recovery from reservoirs is certainly the best known; however they can be effectively applied in many other fields from transportation of crude oil in pipeline to the clean-up of oil storage tanks and even manufacturing of fine petrochemicals. When properly used, biosurfactants are comparable to traditional chemical analogues in terms of performances and offer advantages with regard to environment protection/conservation. This chapter aims at providing an up-to-date overview of biosurfactant roles, applications and possible future uses related to petroleum industry. PMID:20545279

    The existing wind resource, the most favorable locations, applications, and designs of windpowered generators are reviewed, along with descriptions of current and historic wind turbines and lines of research. Coastal regions, plains, hill summits, and mountains with funneling regions are noted to have the highest annual wind averages, with energy densities exceeding the annual solar insolation at average wind speeds of 5-7.9 m/sec. Applications for utility-grade power production, for irrigation, for mechanical heat production, and for pumped storage in water towers or reservoirs are mentioned, as well as electrical power production in remote areas and for hydrogen production by electrolysis. Power coefficients are discussed, with attention given to the German Growian 3 MW machine. It is shown that the least economically sound wind turbines, the machines with outputs below 100 kW, can vie with diesel plant economics in a good wind regime if the wind turbine operates for 15 yr.

    Wound closure is a part of any surgical procedure and the objective of laceration repair or incision closure is to approximate the edges of a wound so that natural healing process may occur. Over the years new biomaterials have been discovered as an alternate to conventional suture materials. Cyanoacrylate bioadhesives are one among them. They carry the advantages of rapid application, patient comfort, resistance to infection, hemostatic properties, and no suture removal anxiety. Hence this s...

  13. Possibilities of Laser Processing of Paper Materials

    Stepanov, Alexander; Saukkonen, Esa; Piili, Heidi

    Nowadays, lasers are applied in many industrial processes: the most developed technologies include such processes as laser welding, hybrid welding, laser cutting of steel, etc. In addition to laser processing of metallic materials, there are also many industrial applications of laser processing of non-metallic materials, like laser welding of polymers, laser marking of glass and laser cutting of wood-based materials. It is commonly known that laser beam is suitable for cutting of paper materials as well as all natural wood-fiber based materials. This study reveals the potential and gives overview of laser application in processing of paper materials. In 1990's laser technology increased its volume in papermaking industry; lasers at paper industry gained acceptance for different perforating and scoring applications. Nowadays, with reduction in the cost of equipment and development of laser technology (especially development of CO2 technology), laser processing of paper material has started to become more widely used and more efficient. However, there exists quite little published research results and reviews about laser processing of paper materials. In addition, forest industry products with pulp and paper products in particular are among major contributors for the Finnish economy with 20% share of total exports in the year 2013. This has been the standpoint of view and motivation for writing this literature review article: when there exists more published research work, knowledge of laser technology can be increased to apply it for processing of paper materials.

  14. Toward a possible next geomagnetic transition?

    Full Text Available The geomagnetic field is subject to possible reversals or excursions of polarity during its temporal evolution. Considering that: (a the typical average time between one reversal and the next (the so-called chron is around 300 000 yr, (b the last reversal occurred around 780 000 yr ago, (c more excursions (rapid changes of polarity can occur within the same chron and (d the geomagnetic field dipole is currently decreasing, a possible imminent geomagnetic reversal or excursion would not be completely unexpected. In that case, such a phenomenon would represent one of the very few natural hazards which are really global. The South Atlantic Anomaly (SAA is a great depression of the geomagnetic field at the Earth's surface, caused by a reverse magnetic flux in the terrestrial outer core. In analogy with critical point phenomena characterised by some cumulative quantity, we fit the surface extent of this anomaly over the last 400 yr with power or logarithmic functions in reverse time, also decorated by log-periodic oscillations, whose final singularity (a critical point tc reveals a great change in the near future (2034 ± 3 yr, when the SAA area reaches almost a hemisphere. An interesting aspect that has been recently found is the possible direct connection between the SAA and the global mean sea level (GSL. That the GSL is somehow connected with SAA is also confirmed from the similar result when an analogous critical-like fit is performed over GSL: the corresponding critical point (2033 ± 11 yr agrees, within the estimated errors, with the value found for SAA. From this result, we point out the intriguing conjecture that tc would be the time of no return, after which the geomagnetic field could fall into an irreversible process of a global geomagnetic transition that could be a reversal or excursion of polarity.

    Corrective measures on the bone undertaken after the fusion of epiphyses are only possible through an initial break in its continuity. This paper deals with the different methods of osteotomy available to the orthopaedic or trauma surgeon. After introducing the terminology of the so-called "osteotomy", the vascularity of the bone, special features of the various osteotomy site, the different indications, and particular details of the operative procedures are discussed. Special emphasis is placed on minimally invasive techniques and osteotomies in the framework of callus distraction. In addition to established procedures a new sawing technique for the Küntscher's closed osteotomy is described. PMID:9446235

    Evidence for the possible existence of a quantum process opposite to the famous Hawking radiation (evaporation) of black holes is presented. This new phenomenon could be very relevant in the case of exotic multiple horizon Nariai black holes and in the context of common grand unified theories. This is clearly manifested in the case of the SO(10) GUT, that is here investigated in detail. The remarkable result is obtained, that anti-evaporation can occur there only in the SUSY version of the th...

  17. About the possibility of a generalized metric

    International Nuclear Information System (INIS)

    The metric (the structure of the space-time) may be dependent on the properties of the object measuring it. The case of size dependence of the metric was examined. For this dependence the simplest possible form of the metric tensor has been constructed which fulfils the following requirements: there be two extremal characteristic scales; the metric be unique and the usual between them; the change be sudden in the neighbourhood of these scales; the size of the human body appear as a parameter (postulated on the basis of some philosophical arguments). Estimates have been made for the two extremal length scales according to existing observations. (author) 19 refs

  18. Valvular Excrescences: A Possible Transient Phenomenon

    Full Text Available The thrombogenic potential of Lambl excrescences (LE is minimal unlike the benign tumour fibroelastoma wherefrom thrombi often originate. We present a patient with multiple strokes within a six-year period. A possible locus on the aortic valve was found and diagnosed as fibroelastoma. Before aortic valve substitution prior finding could not be visualized and surgery was aborted. Due to review of earlier Transesophageal Echocardiography (TEE and the transient component, LE was accepted as the most plausible diagnosis. This illustrates the need for TEE just before surgery.

  19. How is a philosophy of photography possible?

    Full Text Available This paper focuses on the following question: how is philosophy of anything possible? Where lies the boundary of specialisation area beyond which the term “philosophy” loses not only its strength, but also its meaning? When we talk about specific genre, for example, graphic art or sculpture we use the term “philosophy” in a broader, metaphorical sense. Why then should philosophy of photography be any different? All of the abovementioned questions are discussed in the present article. Philosophy of photography is, indeed, a legitimate discipline, just as philosophy of language, philosophy of science and technology and philosophy of politics are.

    Analysis of CCD photometric observations in late 2015 of the Hungaria asteroid 6384 Kervin indicates that it may be a binary asteroid with a primary lightcurve of P1 = 3.6194 ± 0.0001 h, A1 = 0.06 ± 0.01 mag. The secondary lightcurve parameters are P2 = 15.94 ± 0.01 h, A2 = 0.03 ± 0.01 mag. No mutual events (occultations or eclipses) were observed. However, other indicators give an estimated diameter ratio on the order of Ds/Dp ~ 0.3, possibly greater.
