    Full Text Available Enzymes are biological catalysts with increasing application in the food pharmaceutical, cosmetic, textile and chemical industry. They are also important as reagents in chemical analysis, leather fabrications and as targets for the design of new drugs. Keeping in mind the growing need to replace classical chemical processes by alternative ones, because of ever growing environmental pollution, it is important that enzyme and other biotechnological processes are economical. Therefore, price decrease and stability and enzyme preparation efficiency increase are required more and more. This paper presents a short review of methods for yield increase and the improvement of the quality of enzyme products as commercial products, as well as a review of the possibilities of their application.

    Environmental catalysis has been steadily growing because of the advances in its scientific and engineering aspects,as well as due to the new environmental challenges in the industrial era.The development of new catalysts and materials is essential for new technologies for various environmental applications.Ceramics play important roles in various environmental applications including the identification,monitoring,and quantification of pollutants and their control.Ceramics have important applications as sensors and photocatalysts,and they are extensively used as catalyst carriers and supports.Many ceramics are being explored as catalysts for pollution control applications.Their low cost,thermal and chemical stability,and capability of being tailored make them especially attractive for pollution control applications.Although a wide variety of materials have been developed as catalyst supports,this area is still of interest with new or modified catalyst supports being frequently reported.It is of equal importance to develop new or modified processes for the loading of catalysts on specific supports.Applications like chemical looping combustion (CLC) and other catalytic combustion processes are raising the demands to a new scale.We have been working on the development of both new and modified support materials,including mesoporous materials without structural order for possible applications in CLC and other catalytic reactions.Successful attempts have been made in the modification of conventional γ-Al2O3 and improved synthesis processes for supporting perovskite type catalysts.Our research on environmental catalysis applications of ceramic materials and processes are also briefly discussed.

    Since its discovery some 25 years ago, much has been learned about HIV type 1 and the molecular details of its replication cycle. This insight has been used to develop lentiviral vector systems that have advantages over conventional retroviral vector systems. For safety reasons, the lentiviral vector systems are replication incompetent and the risk of generating a replication competent virus has been minimized. Nevertheless, there may be certain applications for replication competent HIV base...

  5. 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.

  6. 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.

  11. 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)

  12. Possible application of brewer’s spent grain in biotechnology

    Directory of Open Access Journals (Sweden)

    Pejin Jelena D.

    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.

  13. 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.

    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.

  17. 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.

    Full Text Available This paper assesses possibilities of a new approach of control map applications on the screen without locomotive system. There is a project about usability of Eye Tracking System in Geoinformatic and Cartographic fields at Department of Geoinformatics at Palacky University. The eye tracking system is a device for measuring eye/gaze positions and eye/gaze movement ("where we are looking". There is a number of methods and outputs, but the most common are "heat-maps" of intensity and/or time. Just this method was used in the first part, where was analyzed the number of common web map portals, especially distribution of their tools and functions on the screen. The aim of research is to localize by heat-maps the best distribution of control tools for movement with map (function "pan". It can analyze how sensitive are people on perception of control tools in different web pages and platforms. It is a great experience to compare accurate survey data with personal interpretation and knowledge. Based on these results is the next step – design of "control tools" which is command by eye-tracking device. There has been elected rectangle areas located on the edge of map (AOI – areas of interest, with special function which have defined some time delay. When user localizes one of these areas the map automatically moves to the way on which edge is localized on, and time delay prevents accidental movement. The technology for recording the eye movements on the screen offers this option because if you properly define the layout and function controls of the map, you need only connect these two systems. At this moment, there is a technical constrain. The solution of movement control is based on data transmission between eye-tracking-device-output and converter in real-time. Just real-time transfer is not supported in every case of SMI (SensoMotoric Instruments company devices. More precisely it is the problem of money, because eye-tracking device and every

    2012-01-01

    Caffeine, a purine alkaloid is a constituent of widely consumed beverages. The scientific evidence which has proved the harm of this alkaloid has paved the way for innumerable research in the area of caffeine degradation. In addition to this, the fact that the by-products of the coffee and tea industry pollute the environment has called for the need of decaffeinating coffee and tea industry's by-products. Though physical and chemical methods for decaffeination are available, the lack of specificity for removal of caffeine in these techniques and their non-eco-friendly nature has opened the area of microbial and enzymatic degradation of caffeine. Another important application of microbial caffeine degradation apart from its advantages like specificity, eco-friendliness and cost-effectiveness is the fact that this process will enable the production of industrially and medically useful components of the caffeine degradation pathway like theobromine and theophylline. This is a comprehensive review which mainly focuses on caffeine degradation, large-scale degradation of the same and its applications in the industrial world.

    2015-08-03

    Natural killer (NK) cells are large granular lymphocytes of the innate immune system, responsible for direct targeting and killing of both virally infected and transformed cells. NK cells rapidly recognize and respond to abnormal cells in the absence of prior sensitization due to their wide array of germline-encoded inhibitory and activating receptors, which differs from the receptor diversity found in B and T lymphocytes that is due to the use of recombination-activation gene (RAG) enzymes. Although NK cells have traditionally been described as natural killers that provide a first line of defense prior to the induction of adaptive immunity, a more complex view of NK cells is beginning to emerge, indicating they may also function in various immunoregulatory roles and have the capacity to shape adaptive immune responses. With the growing appreciation for the diverse functions of NK cells, and recent technological advancements that allow for a more in-depth understanding of NK cell biology, we can now begin to explore new ways to manipulate NK cells to increase their clinical utility. In this overview unit, we introduce the reader to various aspects of NK cell biology by reviewing topics ranging from NK cell diversity and function, mouse models, and the roles of NK cells in health and disease, to potential clinical applications. © 2015 by John Wiley & Sons, Inc.

  11. 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

    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

    We extend the commonly used synthesis strategies for responsive microgels to the design of novel multiresponsive and multifunctional nanoparticles that combine inorganic magnetic, metallic/catalytic and thermoresponsive organic moieties. Magnetic responsiveness is implemented through the integration of silica-coated maghemite nanoparticles into fluorescently labeled crosslinked poly(N-isopropylmethacrylamide) microgels. These particles are then employed as templates for the in situ reduction of catalytically active gold nanoparticles. In order to tune the reactivity of the catalyst through a thermally controlled barrier, an additional layer of crosslinked poly(N-isopropylacrylamide) is added in the final step. We subsequently demonstrate that these particles can be employed as smart catalysts. We show that the thermoresponsive nature of the outer particle shell not only provides control over the catalytic activity, but when combined with a magnetic core allows for very efficient removal of the catalytic system through temperature-controlled reversible coagulation and subsequent magnetophoresis in an applied magnetic field gradient. We finally discuss the use of this design principle for the synthesis of complex hybrid particles for various applications that would all profit from their multiresponsive and multifunctional nature.We extend the commonly used synthesis strategies for responsive microgels to the design of novel multiresponsive and multifunctional nanoparticles that combine inorganic magnetic, metallic/catalytic and thermoresponsive organic moieties.

    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.

    Originally designed to make the practical examination on thermography certification1 possible, the device presented in this paper has demonstrated to be a very useful and versatile didactic tool for training centers and educational institutions, it can also be used as a low cost blackbody simulator to verify calibration of radiometers. It is a simple device with several functionalities for studying and for applications on heat transfer and radiometry, among them the interesting ability to thermally simulate the surface of real objects. On that functionality, if the device is seen by a thermographic camera, it reproduces the surface apparent temperatures of the object that it is simulating, at the same time, if it is seen by a naked eye it shows a visible image of that same surface. This functionality makes the practical study in the classroom possible, from different areas such as electrical, mechanical, medical, building, veterinary, etc.

    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.

    The term 'fourth generation X-ray sources' has come to mean X-ray free-electron lasers which use multi-GeV electron beams from linear accelerators to generate X-rays by self-amplified stimulated emission when fired into long undulators. Properties of the radiation expected from such sources are reviewed briefly and two possible applications of the resulting pulsed highly collimated X-radiation to problems in biology are discussed: use of X-ray photon correlation spectroscopy to measure time correlations of atoms in protein crystals, and use of Mössbauer radiation extracted from the photon beams by resonant Bragg diffraction from (57)Fe-containing crystals, for MAD phasing of very large unit-cell biomolecular crystals and possibly for photon echo measurements.

  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

    CERN Document Server

    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...

    The flashover characteristics of an insulator bridged high voltage vacuum gap can play an important role in the overall performance of a high voltage device, for example in the extreme environments of high energy particle accelerators. The detailed preparation of the insulators is, at present, governed by the commercial production methods and by standard bulk cleaning processes, which for a particular application may be far from optimum. The influence of the mechanical preparation, thermal history and particular cleaning technique have been investigated for commercially available alumina samples, with measurement of surface characteristics by scanning electron microscopy and laser diffraction, measurement of the secondary electron emission curve and analysis of the high voltage performance with the possibility of applied fields up to 200kV/cm. The results of the different measurements are discussed in the overall context of the problems encountered in the full sized high voltage devices, and suggestions are m...

    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. .

  18. 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.

    Mauro, J.J.; Michlewicz, D.; Letizia, A.

    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)

  1. 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

  2. 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.

    Paper presents an analysis of the possibility of application of piezoelectric foils - Macro Fiber Composite (MFC) in modernized freight wagons. It was verified if they can be successfully applied as sensors in developed system for structural health monitoring and in energy harvesting system. It is a part of a research project that aim is to develop a technology of freight wagons modernization. The goal of the project is to elongate the period between periodic repairs (by better corrosion protection) and improve conditions of exploitation of modernized wagons (easier unloading during winter conditions - no freezes of the charge to the freight wagon body shell). The additional aim is to develop system for structural health monitoring of the modernized body of the freight wagon as well as the system supporting management of a fleet of wagons using GPS system with power supply based on the energy recovered by MFC's from the wagon's vibrations during its exploitation. Results of laboratory tests as well as results of measurements on the real freight wagon during observed driving of the wagon are presented. At the same time measurements of the electric voltage generated by the MFC transducers excited by low frequencies harmonic excitation were verified.

    2014-04-01

    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.

  5. Estimation of effective temperatures in quantum annealers for sampling applications: A case study with possible applications in deep learning

    2016-08-01

    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.

It leads to electron-positron instability of vacuum and generation of pairs. As positrons are thrown out by electric field, and electrons are trapped, the black hole works as a factory of antimatter, transforming protons into antiparticles. Reference: 1. E.P.

  7. 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

  4. 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

  5. Removal of pollutants from surface water and groundwater by nanofiltration: overview of possible applications in the drinking water industry

    International Nuclear Information System (INIS)

    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

  18. Complexity of EEG-signal in Time Domain - Possible Biomedical Application

    Science.gov (United States)

    Klonowski, Wlodzimierz; Olejarczyk, Elzbieta; Stepien, Robert

    2002-07-01

    Human brain is a highly complex nonlinear system. So it is not surprising that in analysis of EEG-signal, which represents overall activity of the brain, the methods of Nonlinear Dynamics (or Chaos Theory as it is commonly called) can be used. Even if the signal is not chaotic these methods are a motivating tool to explore changes in brain activity due to different functional activation states, e.g. different sleep stages, or to applied therapy, e.g. exposure to chemical agents (drugs) and physical factors (light, magnetic field). The methods supplied by Nonlinear Dynamics reveal signal characteristics that are not revealed by linear methods like FFT. Better understanding of principles that govern dynamics and complexity of EEG-signal can help to find `the signatures' of different physiological and pathological states of human brain, quantitative characteristics that may find applications in medical diagnostics.

  19. 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)

Vacuum-therapy was conducted with the help of negative pressure apparatus "AGATE-Dnepr" (Ukraine) by attaching silver-containing polyurethane sponge on the operating zone, covering the flap with the surrounding skin netting band "Grassolind". The recommended standard of negative pressure of 75-125 mm Hg, both in impulse and in continuous mode was used. The high efficiency of vacuum-therapy for survival of grafts has been demonstrated. Thus, it might be considered as an effective element of prevention and treatment of complications associated with venous insufficiency or trombosis using of vascularised tissue complex plastics of defects.

    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.

    Gene-environment interaction, a key idea in molecular epidemiology, has enabled the development of personalized medicine. This concept includes personalized prevention. While genome-wide association studies have identified a number of genetic susceptibility loci in breast cancer risk, however, the application of this knowledge to practical prevention is still underway. Here, we briefly review the history of molecular epidemiology and its progress in breast cancer epidemiology. We then introduce our experience with the trial combination of GWAS-identified loci and well-established lifestyle and reproductive risk factors in the risk prediction of breast cancer. Finally, we report our exploration of the cumulative risk of breast cancer based on this risk prediction model as a potential tool for individual risk communication, including genetic risk factors and gene-environment interaction with obesity.

    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)

    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.

  6. 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.

    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...

  8. The Cyclic Antibacterial Peptide Enterocin AS-48: Isolation, Mode of Action, and Possible Food Applications

    Directory of Open Access Journals (Sweden)

    María José Grande Burgos

    2014-12-01

    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.

    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 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.

    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.

  12. 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

    Non-thermal atmospheric-pressure plasma, also named cold plasma, is defined as a partly ionized gas. Therefore, it cannot be equated with plasma from blood; it is not biological in nature. Non-thermal atmospheric-pressure plasma is a new innovative approach in medicine not only for the treatment of wounds, but with a wide-range of other applications, as e.g. topical treatment of other skin diseases with microbial involvement or treatment of cancer diseases. This review emphasizes plasma effects on wound healing. Non-thermal atmospheric-pressure plasma can support wound healing by its antiseptic effects, by stimulation of proliferation and migration of wound relating skin cells, by activation or inhibition of integrin receptors on the cell surface or by its pro-angiogenic effect. We summarize the effects of plasma on eukaryotic cells, especially on keratinocytes in terms of viability, proliferation, DNA, adhesion molecules and angiogenesis together with the role of reactive oxygen species and other components of plasma. The outcome of first clinical trials regarding wound healing is pointed out.

    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.

    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.

  16. 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)

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

    1998-02-27

    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

  18. 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.

    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.

  20. 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

  1. 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

    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.

    Full Text Available 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, not 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 arises: maxima and minima appear for the n—dimensional 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 be related to the 3—dimensional nature of the universe.

    2016-06-01

    In Poland, in recent years, there has been a rapid accumulation of sewage sludge - a by-product in the treatment of urban wastewater. This has come about as a result of infrastructure renewal, specifically, the construction of modern sewage treatment plants. The more stringent regulations and strategic goals adopted for modern sewage management have necessitated the application of modern engineering methodology for the disposal of sewage sludge. One approach is incineration. As a consequence, the amount of fly ash resulting from the thermal treatment of municipal sewage sludge has grown significantly. Hence, intensive work is in progress for environmentally safe management of this type of waste. The aim of the experiment was to evaluate the possibility of using the fly ash that results from municipal sewage sludge thermal treatment (SSTT) as an additive to hardening slurries. This type of hardening slurry with various types of additives, e.g. coal combustion products, is used in the construction of cut-off walls in hydraulic structures. The article presents the technological and functional parameters of hardening slurries with an addition of fly ash obtained by SSTT. Moreover, the usefulness of these slurries is analysed on the basis of their basic properties, i.e. density, contractual viscosity, water separation, structural strength, volumetric density, hydraulic conductivity, compressive and tensile strength. The mandated requirements for slurries employed in the construction of cut-off walls in flood embankments are listed as a usefulness criteria. The article presents the potential uses of fly ash from SSTT in hardening slurry technology. It also suggests directions for further research to fully identify other potential uses of this by-product in this field.

    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.

  14. Discovery of possible gene relationships through the application of self-organizing maps to DNA microarray databases.

    Directory of Open Access Journals (Sweden)

    Rocio Chavez-Alvarez

    Full Text Available DNA microarrays and cell cycle synchronization experiments have made possible the study of the mechanisms of cell cycle regulation of Saccharomyces cerevisiae by simultaneously monitoring the expression levels of thousands of genes at specific time points. On the other hand, pattern recognition techniques can contribute to the analysis of such massive measurements, providing a model of gene expression level evolution through the cell cycle process. In this paper, we propose the use of one of such techniques--an unsupervised artificial neural network called a Self-Organizing Map (SOM-which has been successfully applied to processes involving very noisy signals, classifying and organizing them, and assisting in the discovery of behavior patterns without requiring prior knowledge about the process under analysis. As a test bed for the use of SOMs in finding possible relationships among genes and their possible contribution in some biological processes, we selected 282 S. cerevisiae genes that have been shown through biological experiments to have an activity during the cell cycle. The expression level of these genes was analyzed in five of the most cited time series DNA microarray databases used in the study of the cell cycle of this organism. With the use of SOM, it was possible to find clusters of genes with similar behavior in the five databases along two cell cycles. This result suggested that some of these genes might be biologically related or might have a regulatory relationship, as was corroborated by comparing some of the clusters obtained with SOMs against a previously reported regulatory network that was generated using biological knowledge, such as protein-protein interactions, gene expression levels, metabolism dynamics, promoter binding, and modification, regulation and transport of proteins. The methodology described in this paper could be applied to the study of gene relationships of other biological processes in different organisms.

  16. Possibilities of the new hybrid technology single photon emission computer technology/computer tomography (SPECT/CT) and the first impressions of its application

    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. It is now accepted, that its usage will increase in

    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.

    The interface between graphene and organic layers is a key factor responsible for the performance of gra-phene-based organic solar cells (OSCs). In this paper, we focus on coating PEDOT:PSS onto the surface of graphene. We demonstrate two approaches, applying UV/Ozone treatment on graphene and modifying PEDOT:PSS with Zonyl, to get a PEDOT:PSS well-coated graphene film . Our results prove that both methods can be effective to solve the interface issue between graphene and PEDOT: PSS. Thereby it shows a positive application of the composited gra-phene/PEDOT:PSS film on graphene-based OSCs.

  8. 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

    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.

    The purpose of this article was to examine the application of the International Classification of Functioning, Disability, and Health (ICF) in the field of psychiatry in the last 10 yrs since the ICF was launched. The hypothesis is that the application of the ICF in the field of psychiatry has not been yet much explored. Therefore, the objective of this article was to provide reasons to explain the difficult implementation of the ICF in this field, which in turn, might account for the lack of studies. A literature search was conducted using the terms ICF AND mental illness OR mental disorders OR psychiatry in titles, abstracts, and key words of articles collected in the databases ISI Web of Knowledge, ScienceDirect and Medline from 2001 to 2010. A total of 64 full-length articles were retrieved and reviewed, and among them, 13 were eventually included in this review because they were related to the ICF in psychiatry. Of the 13 studies identified concerning the ICF and mental disorders, 7 focus on the implementation of the ICF in the clinical practice, and 6 are theoretical papers discussing the potential benefits of the ICF for the field of psychiatry. A number of reasons can be suggested to explain the paucity of studies on the use of the ICF in psychiatry in the last 10 yrs: (1) the novelty of the ICF and the dominance of the medical model, (2) the belief that disability is just about physical conditions, (3) the influence of medication on capacity and performance, (4) the complex structure of the ICF, (5) the intrinsic limitations of the ICF, and (6) limitations in the accessibility of the ICF to some medical professionals.

    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

  17. Dynamically forced cantilever system: A piezo-polymer characterization tool with possible application for micromechanical HF resonator devices

    A cantilever system, driven to a dynamically forced oscillation by a small piezoelectric specimen is presented as a simple and accurate tool to determine the converse dynamic piezocoefficient up to several kHz. The piezoelectric sample is mounted on top of a reflective cantilever where it is free to oscillate without any mechanical constraint. A Nomarsky-interferometer detects the induced cantilever displacement. The presented technique is especially suited for a precise characterization of small and soft piezoelectric polymer-samples with rough surfaces. The capability of the dynamically forced cantilever principle is demonstrated with a LiNbO3 crystal and with a porous ferroelectretic polypropylene foam. Results from measurements between 400 Hz and 5 kHz were found to be in excellent agreement with published values. Additionally, the dynamically forced cantilever principle may possibly improve the sensitivity of some micromechanical cantilever-sensors and it could also be interesting for the design of enhanced micromechanical high frequency mixer filters. Some ideas about are briefly presented.

    We investigated electron transport characteristics of wide-band polar semi-conductors with intermediate strength of the electron-phonon interaction. Electron energy loss to the lattice was calculated as a function of electron velocity for various materials in the frameworks of (a) a perturbative approach based on the calculation of scattering rates from Fermi's golden rule and (b) a non-perturbative approach based on the path-integral formalism of Thornber and Feynman. Our results suggest that the standard perturbative treatment can be applied to GaN and AlN despite the relatively strong electron-phonon coupling in this material system, with intercollision times of the order of the period of the phonon oscillation. Our findings also indicate the possibility for unique long-distance runaway transport in nitrides which may occur at the pre-threshold electric fields. The polaron ground-state energy and effective masses are calculated for GaN and AlN as well as for GaAs and Al{sub 2}O{sub 3}. An expression for the Froehlich coupling constant for wurtzites is derived. (author)

    Case-based reasoning (CBR) is a unique tool for the evaluation of possible failure of firms (EOPFOF) for its eases of interpretation and implementation. Ensemble computing, a variation of group decision in society, provides a potential means of improving predictive performance of CBR-based EOPFOF. 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.

  20. On the generation mechanism of terminator times in subionospheric VLF/LF propagation and its possible application to seismogenic effects

    2008-02-01

    Full Text Available The signals from VLF/LF transmitters are known to propagate in the Earth-ionosphere waveguide, so that the subionospheric propagation characteristics are very sensitive to the condition of the lower ionosphere. We know that there appear the terminator times just around the sunrise and sunset in the diurnal variation of subionospheric VLF/LF signal (amplitude and phase. These terminator times are found to shift significantly just around an earthquake, which enables us to infer the change in the ionosphere during the earthquake. In this paper we try to understand the physical mechanism on the generation of those terminator times for relatively short propagation path (less than 2000 km by means of wave-hop method. It is found that the lowering of the ionosphere boundary during an earthquake decreases the path length of the sky wave and this alters the interference condition of this wave with the ground wave, which lead to an appearance of terminator times as the destructive interference between the ground and sky waves. Finally, we suggest a possible use of terminator time shifts to investigate the lower ionospheric plasma changes during the earthquakes.

  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.

    2013-12-01

    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.

    Full Text Available The task of this work was to construct the mixed matrix membrane based on polymer that could be used for the treatment of the waste gases. Therefore, high permeability for the carbon dioxide and low permeability for other gases commonly present in the industrial combustion waste gases (nitrogen, oxygen, hydrogen, methane are essential. Those membranes belong to the group of dense composite membranes, and mechanism for separation is based on the solution-diffusion mechanism. In this paper, feasibility of the application of poly(ethyleneoxid-copoly(phtalamide was tested. In order to enchase the permeability of carbon dioxide, three different zeolites were incorporated, and in order to improve compatibility between the inorganic particles and polymer chains, n-tetradecyldimethylamonium bromide (NTAB.was added. Three zeolites were with the 2-dimensional pores (IHW, NSI and TER. The best results in carbon dioxide/hydrogen selectivity were obtained with the membrane constructed with PEBAX 1657 and surface treated zeolites, while the better results concerning selectivity were gained with membranes based on the Polyactive.

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

    Bor-Shouh Huang

    2013-01-01

    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.

    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

    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

    Full text: We have analyzed a large set of {alpha}-{alpha} elastic scattering data for bombarding energies ranging from 0.6 to 29.5 MeV. The complete lack of open reaction channels at these somehow low energies results in a vanishing imaginary part for the optical interaction. This characteristic makes the {alpha}-{alpha} reaction particularly interesting as the corresponding elastic scattering cross sections and phase shifts become very sensitive to the real part of the interaction. The data were analyzed within the context of the velocity-dependent Sao Paulo potential, which is a successful theoretical model for the description of heavy-ion reactions from sub-barrier to intermediate energies. We have shown that, even in this low energy region, the velocity dependence of the Sao Paulo potential model is a necessary ingredient for describing the data. Despite the reasonable description obtained with the Sao Paulo potential, the analyses indicate the necessity of an additional weak dependence of the interaction on the angular momentum. These important characteristics open the possibility for studying reactions with astrophysical interested. In particular, predictions of the astrophysical S-factor for the {sup 12}C({alpha},{gamma}) reaction will be presented. The understanding of the reaction rate for the {alpha}-capture process by a {sup 12}C nucleus is a crucial ingredient for predicting the stellar helium burning and the subsequent fate of stars as this reaction determines the ratio of carbon to oxygen towards the end of the Red Giants phase. It is well known that low mass stars evolve to White Dwarfs and this ratio determines the final abundance composition in White Dwarf matter and sets the trigger conditions for type Ia supernova explosions. The carbon-oxygen ratio also dictates the subsequent sequence of burning processes during the final stages of stellar evolution for massive stars. Thus, it has a key role in the determination of the abundance composition in

    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 ...

  11. 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

    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.

  14. 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.

    Knowing how to weld dissimilar metals is becoming more and more important. One reason is that it's often impossible for one material to provide the optimum chemical, physical, and mechanical characteristics needed for an application. For this reason, as well as cost efficiency, technology specialists are experimenting with different joining processes to weld bimetal joints optimally. A reliable method of joining the two most commonly used metals, steel and aluminum, would make it possible to make these joints in several applications. On one hand, aluminum is becoming increasingly more important in the automotive industry because of its good processing and performance characteristics and because it's lightweight, which results in lower fuel consumption. Given today's heightened need to decrease energy consumption, aluminum is a major player in modern-day mechanical engineering. On the other hand, steel continues to dominate many fields of engineering, a fact underlined by the development of high-strength and superhigh-strength steels. When different metals are joined, each metal's features should be considered. It's important to pay attention to the chemical and physical properties-such as the corrosion behavior and thermal expansion coefficient-and to atomic properties, such as the lattice constant and type of crystalline lattice. Processes typically used to join dissimilar metals are bonding, riveting, or clinching, which essentially have no influence on the metals' atomic properties. Another method, thermal joining, can shorten joining time, produce tight seams, and provide high strength. (orig.)

    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

    Full Text Available Development of the 4-component meningococcal serogroup B vaccine (4CMenB has required new assays for the reliable evaluation of the expression and cross-reactivity of those specific antigen variants that are predicted to be targeted by bactericidal antibodies elicited by the vaccine in different isolates. Existing laboratory techniques, such as multilocus sequence typing, are poorly suited to this purpose, since they do not provide information on the contribution of single vaccine components and therefore cannot be applied to estimate the potential coverage of the multicomponent vaccine. The hSBA, the only correlate of protection against invasive meningococcal disease accepted thus far, cannot conveniently be used to test large number of strains. To overcome these issues, the meningococcal antigen typing system (MATS has been specifically developed in order to predict 4CMenB coverage of individual meningococcus serogroup B strains. To date, MATS has proved advantageous for several reasons, including its ability to assess both qualitative and quantitative aspects of surface antigens of single strains in a highly reproducible, rapid, and resource-saving manner, while its shortcomings include a possible underestimation of 4CMenB coverage and the use of pooled sera to calculate the positive bactericidal threshold. This paper provides an overview of MATS development and its field application.

    Development of the 4-component meningococcal serogroup B vaccine (4CMenB) has required new assays for the reliable evaluation of the expression and cross-reactivity of those specific antigen variants that are predicted to be targeted by bactericidal antibodies elicited by the vaccine in different isolates. Existing laboratory techniques, such as multilocus sequence typing, are poorly suited to this purpose, since they do not provide information on the contribution of single vaccine components and therefore cannot be applied to estimate the potential coverage of the multicomponent vaccine. The hSBA, the only correlate of protection against invasive meningococcal disease accepted thus far, cannot conveniently be used to test large number of strains.

    Achieving accurate measurements of inflammation levels in tissues or thickness changes in biological membranes (e.g., amniotic sac, parietal pleura) and thin biological walls (e.g., blood vessels) from outside the human body, is a promising research line in the medical area. It would provide a technical basis to study the options for early diagnosis of some serious diseases such as hypertension, atherosclerosis or tuberculosis. Nevertheless, achieving the aim of non-invasive measurement of those scarcely-accessible parameters on patient internal tissues, currently presents many difficulties. The use of high-frequency ultrasonic transducer systems appears to offer a possible solution. Previous studies using conventional ultrasonic imaging have shown this, but the spatial resolution was not sufficient so as to permit a thickness evaluation with clinical significance, which requires an accuracy of a few microns. In this paper a broadband ultrasonic technique, that was recently developed by the authors to address other non-invasive medical detection problems (by integrating a piezoelectric transducer into a spectral measuring system), is extended to our new objective; the aim is its application to the thickness measurement of sub-millimeter membranes or layers made of materials similar to some biological tissues (phantoms). The modeling and design rules of such a transducer system are described, and various methods of estimating overtones location in the power spectral density (PSD) are quantitatively assessed with transducer signals acquired using piezoelectric systems and also generated from a multi-echo model. Their effects on the potential resolution of the proposed thickness measuring tool, and their capability to provide accuracies around the micron are studied in detail. Comparisons are made with typical tools for extracting spatial parameters in laminar samples from echo-waveforms acquired with ultrasonic transducers. Results of this advanced measurement

    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.

    2016-01-01

    We present the results of a cluster search in the Fermi-LAT Pass 8 gamma-ray sky by means of the Minimum Spanning Tree algorithm, at energies higher than 10 GeV and at Galactic latitudes higher than 25 degrees. The selected clusters have a minimum number of photons higher than or equal to 5, a high degree of concentration, and are without a clear corresponding counterpart in blazar catalogues. A sample of 30 possible gamma-ray sources was obtained. These objects were verified by applying the standard Maximum Likelihood analysis on the Fermi-LAT data. A search for possible radio counterparts in a circle having a radius of 6 arcmin was performed, finding several interesting objects, the majority of them without optical spectroscopical data. These can be considered as new blazar candidates. Some of them were already noticed as possible blazars or Active Galactic Nuclei in previous surveys, but never associated with high energy emission. These possible counterparts are reported and their properties are discussed.

  4. 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)

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

    In this paper we study the possibility to discriminate the mass of the primary cosmic ray by observing the muon arrival times in ground detectors. We analyzed extensive air showers (EAS) induced by proton and iron nuclei with the same energy 8 Multiplication-Sign 10{sup 17} eV simulated with CORSIKA, and analyzed the muon arrival times at ground measured by the infill array detectors of the Pierre Auger Observatory (PAO). From the arrival times of the core and of the muons the atmospheric depth of muon generation locus is evaluated. The results suggest a potential mass discrimination on the basis of muon arrival times and of the reconstructed atmospheric depth of muon production. An analysis of a larger set of CORSIKA simulations carried out for primary energies above 10{sup 18} eV is in progress.

    One of the major challenges in direct methanol fuel cells (DMFCs) is to design reliable and stable FC systems that satisfy the very high dynamic demand in various environmental conditions for portable devices. This paper provides an overview of several failure modes and effect analyses (FMEAs) which can have significant consequences on the durability and stability of DMFCs, including high and sub-zero temperature storage, dry and high humidification atmospheres, and fuel/oxidation starvation by breakdown of fuel/air supply components. Firstly, some characterization methods are discussed to investigate changes of membrane electrode assemblies (MEAs) in terms of their physiochemical and electrochemical properties after testing in various simulated failure modes. Secondly, possible mitigating solutions to minimize the hazards associated with them are suggested through a fundamental understanding and scientific approach. The relationship between the causes and symptoms in DMFC systems is determined by examining a variety of failure sources. (author)

    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.

    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. Ergebnisse: Die Auswertung ergab bei allen untersuchten Parametern keinen wesentlichen Unterschied zwischen den

    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.

    2009-01-01

    The origin of Earth oceans is controversial. Earth could have acquired its water either from hydrated silicates (wet Earth scenario) or from comets (dry Earth scenario). [HDO]/[H2O] ratios are used to discriminate between the scenarios. High [HDO]/[H2O] ratios are found in Earth oceans. These high ratios are often attributed to the release of deuterium enriched cometary water ice, which was formed at low gas and dust temperatures. Observations do not show high [HDO]/[H2O] in interstellar ices. We investigate the possible formation of high [HDO]/[H2O] ratios in dense (nH> 1E6 cm^{-3}) and warm gas (T=100-1000 K) by gas-phase photochemistry in the absence of grain surface chemistry. We derive analytical solutions, taking into account the major neutral-neutral reactions for gases at T>100 K. The chemical network is dominated by photodissociation and neutral-neutral reactions. Despite the high gas temperature, deuterium fractionation occurs because of the difference in activation energy between deuteration enrich...

    Novel lead-graphene and lead-graphite metallic composites which melt at temperature of the melting point of lead were investigated as possible positive current collectors for lead acid batteries in sulfuric acid solution. Scanning electron microscopy, Raman spectroscopy, difference scanning calorimetry, cyclic voltammetry and prolonged corrosion tests were employed to characterize the effect of the newly proposed lead-carbon metallic composites on the structure and electrochemical properties of positive grid material. Both lead-graphene and lead-graphite metallic composite materials show the similar electrochemical characteristics to metallic lead in the voltage range where the positive electrodes of lead acid batteries operate. It has been shown that carbon both as graphene and graphite does not participate in the electrochemical process but improve corrosion and electrochemical characteristics of both metallic composite materials. No products of interaction of lead with sulfuric acid were formed on the surface of graphene and graphite so as it was not found additional peaks of carbon discharge on voltammograms which could be attributed to the carbon. Graphene inclusions in lead prevent formation of leady oxide nanocrystals which deteriorate discharge characteristics of positive electrode of LAB. Both lead-graphene alloy and lead-graphite metallic composite proved excellent electrochemical and corrosion behavior and can be used as positive grids in lead acid batteries of new generation.

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

    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.

    The internal assessment constitutes a desirable capacity for thermalhydraulic system codes allowing the achievement of uncertainty bands associated with any code-calculation result. Currently, the CIAU (Code with - the capability of - Internal Assessment of Uncertainty) is derived from the UMAE (Uncertainty Methodology based on the Accuracy Extrapolation), through other uncertainty methodologies can be used for the same purpose. Therefore, the system code, Relap5 in the present case, is coupled with the uncertainty methodology and constitutes the CIAU. The idea at the basis of CIAU is the identification and the characterization of standard plant statuses and the association of uncertainty to each status. One hypercube and one time interval identify the plant status. Quantity and Time uncertainties are combined for each plant status. In the present paper, the derivation of the methodology is outlined and typical results of PWR (Pressurized Water reactor) plant transients are shown bounded by the CIAU calculated uncertainty bands. Results of a bifurcation study are shown and the possibility of integrating the methodology within the licensing process is discussed. (author)

    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

    Laser surgery provides clean, fast and accurate modeling of tissue. However, the inability to determine what kind of tissue is being ablated at the bottom of the cut may lead to the iatrogenic damage of structures that were meant to be preserved. In this context, nerve preservation is one of the key challenges in any surgical procedure. One example is the treatment of parotid gland pathologies, where the facial nerve (N. VII) and its main branches run through and fan out inside the glands parenchyma. A feedback system that automatically stops the ablation to prevent nerve-tissue damage could greatly increase the applicability and safety of surgical laser systems. In the present study, Laser Induced Breakdown Spectroscopy (LIBS) is used to differentiate between nerve and gland tissue of an ex-vivo pig animal model. The LIBS results obtained in this preliminary experiment suggest that the measured spectra, containing atomic and molecular emissions, can be used to differentiate between the two tissue types. The measurements and differentiation were performed in open air and under normal stray light conditions.

  3. 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.

  4. 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.

    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.

    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.

    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.

    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.

  10. 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.

  12. 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

    In quantum computational logics meanings of formulas are identified with quantum information quantities: systems of qubits or, more generally, mixtures of systems of qubits. We consider two kinds of quantum computational semantics: (1) a compositional semantics, where the meaning of a compound formula is determined by the meanings of its parts; (2) a holistic semantics, which makes essential use of the characteristic “holistic” features of the quantum-theoretic formalism. The compositional and the holistic semantics turn out to characterize the same logic. In this framework, one can introduce the notion of quantum-classical truth table, which corresponds to the most natural way for a quantum computer to calculate classical tautologies. Quantum computational logics can be applied to investigate different kinds of semantic phenomena where holistic, contextual and gestaltic patterns play an essential role (from natural languages to musical compositions).

    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.

    This report discusses the application of norm cost models to income regulation of distribution networks in the electric power sector. It deals in particular with the possibility of using activity based costing (ABC), but also discusses more general use of structural cost models in income regulation. The report presents experiences with the ABC method in various regulated service industries. For income regulation in the network activities, the relevance of ABC based systems is primarily related to activities conducted by the number of customers. Analyses of costs in the sector show large variations in these costs, which may indicate a potential for this type of regulation model. Finally the report discusses the handling of capital costs in the regulation model, which is important for any regulation regime.

  3. 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)

  6. From Necessity to Possibility

    Directory of Open Access Journals (Sweden)

    Charles Cullum

    2015-12-01

    Full Text Available This article applies theories of fragmented postmodern identity and Heidegger’s modes of existence and concept of historicality to the issue of passing and traces the treatment of that motif across six African American novels that move from the largely realistic perspective of the 19th century to the subjectivist perspective of the early 20th century. These novels thus foreshadow the postmodernist questioning of the basis of discrete personal identity. The article claims that, across these novels, the act of passing and its relationship to human identity through time and historical circumstance becomes problematized from a necessary tool for escaping slavery, and so sustaining identity in its most basic form as life itself, to a potential existential dilemma of identity as a matter of authenticity and possibility. The article further discusses whether the individual is constrained by his or her background, especially, by race itself, or is a totally free, ungrounded agent.

  7. Increasing Possibilities of Nanosuspension

    Full Text Available Nowadays, a very large proportion of new drug candidates emerging from drug discovery programmes are water insoluble and thus poorly bioavailable. To avoid this problem, nanotechnology for drug delivery has gained much interest as a way to improve the solubility problems. Nano refers to particles size range of 1–1000 nm. The reduction of drug particles into the submicron range leads to a significant increase in the dissolution rate and therefore enhances bioavailability. Nanosuspensions are part of nanotechnology. This interacts with the body at subcellular (i.e., molecular scales with a high degree of specificity and can be potentially translated into targeted cellular and tissue-specific clinical applications designed to achieve maximal therapeutic efficacy with minimal side effects. Production of drugs as nanosuspensions can be developed for drug delivery systems as an oral formulation and nonoral administration.

    DEFF Research Database (Denmark)

    Rudkjøbing, Laura Aviaja; Esserlind, Ann-Louise; Olesen, Jes

    2012-01-01

    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...

  9. Dental caries: Therapeutic possibilities

    2008-01-01

    Full Text Available Contemporary tendencies in dentistry are based on the concept of maximal protection of healthy tooth tissues. Caries removal has been done traditionally with mechanical rotary instruments that are fast and precise. However, conventional cavity preparation has potential adverse effects to the pulp due to heat, pressure and vibrations. Moreover, drilling often causes pain and requires local anaesthesia, and these procedures are frequently perceived as unpleasant. Etiology, development and prevention of dental caries are better understood today and new restorative materials that bond micromechanically and/or chemically to dental tissues have been introduced. Thus, development of a new, less destructive caries removal technique is allowed. In the last decades, many alternative methods have been introduced in an attempt to replace rotary instruments. These are claimed to be efficient and selective for diseased tissues and to offer comfortable treatment to the patients. New methods include air abrasion, air polishing, ultrasonic, polymer burs, enzymes, systems for chemo-mechanical caries removal, and lasers. The aim of this paper was to discuss various caries removal techniques and possibilities of their use in clinical practice. Based on the literature review it can be concluded that none of the new caries removal methods can completely replace conventional rotary instruments.

    The deep sequencing of 16S rRNA genes amplified by universal primers has revolutionized our understanding of microbial communities by allowing the characterization of the diversity of the uncultured majority. However, some universal primers also amplify eukaryotic rRNA genes, leading to a decrease in the efficiency of sequencing of prokaryotic 16S rRNA genes with possible mischaracterization of the diversity in the microbial community. In this study, we compared 16S rRNA gene sequences from genome-sequenced strains and identified candidates for non-degenerate universal primers that could be used for the amplification of prokaryotic 16S rRNA genes. The 50 identified candidates were investigated to calculate their coverage for prokaryotic and eukaryotic rRNA genes, including those from uncultured taxa and eukaryotic organelles, and a novel universal primer set, 342F-806R, covering many prokaryotic, but not eukaryotic, rRNA genes was identified. This primer set was validated by the amplification of 16S rRNA genes from a soil metagenomic sample and subsequent pyrosequencing using the Roche 454 platform. The same sample was also used for pyrosequencing of the amplicons by employing a commonly used primer set, 338F-533R, and for shotgun metagenomic sequencing using the Illumina platform. Our comparison of the taxonomic compositions inferred by the three sequencing experiments indicated that the non-degenerate 342F-806R primer set can characterize the taxonomic composition of the microbial community without substantial bias, and is highly expected to be applicable to the analysis of a wide variety of microbial communities.

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.

  13. 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)

    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.

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

    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.

    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.

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.

    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...

    Full Text Available In today’s society, companies seem to all be following the same trend; growth in profitability at all cost. Higher profits, for the most part, leads to more investors and more potential financing. Amazon.com appears to be breaking that trend, however. Their strategy seems to be growth, but not in profits. We would like to look into how and why Amazon is growing at such a fast pace, while their profits are staying steady at a very low level. Is profitability a possibility for Amazon? We believe that a marginal increase in price could accomplish just that, with a minimal impact to consumers.

    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.

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.

    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.

    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.

    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.

    Full Text Available In recent years, it has been evident that one form of competitive advertising gained in its importance - comparative advertising. Although its extensive use has probably been inspired by the belief that the perception of relative superiority of a brand compared to competition could be encouraged in that way, research evidence suggested mixed conclusions about its effectiveness. The paper summarizes the results of previous studies in this area, and in particular those which point out the factors that can influence effectiveness of comparative advertising. Additionally,, the paper summarizes the opinions of some authors about the long-term influence of this form of advertising on brand, and gives the recommendations for its more effective use. .

    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.

    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.

    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.

    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.

    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.

    2008-01-01

    Contemporary tendencies in dentistry are based on the concept of maximal protection of healthy tooth tissues. Caries removal has been done traditionally with mechanical rotary instruments that are fast and precise. However, conventional cavity preparation has potential adverse effects to the pulp due to heat, pressure and vibrations. Moreover, drilling often causes pain and requires local anaesthesia, and these procedures are frequently perceived as unpleasant. Etiology, development and prevention of dental caries are better understood today and new restorative materials that bond micromechanically and/or chemically to dental tissues have been introduced. Thus, development of a new, less destructive caries removal technique is allowed. In the last decades, many alternative methods have been introduced in an attempt to replace rotary instruments. These are claimed to be efficient and selective for diseased tissues and to offer comfortable treatment to the patients. New methods include air abrasion, air polishing, ultrasonic, polymer burs, enzymes, systems for chemo-mechanical caries removal, and lasers. The aim of this paper was to discuss various caries removal techniques and possibilities of their use in clinical practice. Based on the literature review it can be concluded that none of the new caries removal methods can completely replace conventional rotary instruments.

    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.

  1. 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

  2. How Does Moxibustion Possibly Work?

    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.

  4. 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

    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)

    The implementation of wastewater reuse is becoming an increasingly important means of supplementing water supply needs and/or reducing costs. The present paper provides examples of possible uses of treated domestic effluent for the three sectors, i.e. public water supply, industrial and agricultural uses with the aim to address the feasibility of these applications. It is concluded that, although The Netherlands as a whole is considered to be a low water stressed country, regional fresh water scarcity and costs can result in the need for applications of domestic wastewater reuse.

  16. Fusion applications study: FAME

    Energy Technology Data Exchange (ETDEWEB)

    Schultz, K.R.

    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.

    1993-07-01

    Gelatin capsules containing squalane partially purified bone morphogenetic protein (BMP) complex were placed on the perimuscular membrane of rats. Two kinds of control, gelatin capsules containing only BMP and those bearing squalane only, were used. The embedded areas were histopathologically examined at 3 and 6 wk after the operation. The observations revealed that the squalane/BMP complex elicited wide heterotopic bone formation with bone marrow tissue, suggesting that squalane is a possible carrier of BMP for clinical applications.

  9. Making Space Travel to Jupiter Possible

    From man landing on the moon to a simple satellite being launched into orbit, many incredible space accomplishments have been witnessed by us all. However, what goes un-noticed to the common man is the extensive research and testing that lasts months, years, and even decades. Much of this required research just so happens to take place in the corridors of the Glen Research Center building number 49. In the Advanced Materials division of G.R.C., a number of researchers have the responsibility of discovering which metal, ceramic, or polymer is best for a specific application. Under the guidance of mentor extraordinaire Frank Ritzert, I am involved in many critical projects dealing with refractory metals, two of which I will mention in this report. The Jupiter Icy Moons Orbiter (JIMO) project actually was under full swing back in the 50's and early 60's. To enable the 14 year trek to the icy moons of Europa, Callisto, and Ganymede, nuclear propulsion methods were selected. Due to the extreme temperature of the reactor and the extended time period, a refractory metal would need to be implemented. After years of research and progress, the program was suddenly canceled. About a decade ago, the JIMO project was re-instated and now has a goal for departure around 2014. However, a few obstacles lie in our way concerning the use of refractory metals. In certain areas of the orbiter a joint is required between the refractories and other less dense metals. Two of these joints are with nickel based super alloys. Being an intern for Frank Ritzert, the refractory metals expert, I have the opportunity to develop the best method to braze refractory metals to Nickel 201. This involves the actual brazing, electron microscopy and reporting the results. My second project involves a certain part of the orbiter where Niobium 1Zirconium, a refractory metal, is joined with Hastelloy-X a Ni based metal. Small quantities of oxygen, helium and other impurities in the Ni alloy could diffuse

    Goodman, Nathan A; Potter, Lee C

    2015-03-10

    In this paper, we consider the application of compressive sensing (CS) to radar remote sensing applications. We survey a suite of practical system-level issues related to the compression of radar measurements, and we advocate the consideration of these issues by researchers exploring potential gains of CS in radar applications. We also give abbreviated examples of decades-old radio-frequency (RF) practices that already embody elements of CS for relevant applications. In addition to the cautionary implications of system-level issues and historical precedents, we identify several promising results that RF practitioners may gain from the recent explosion of CS literature.

  11. 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...

This ETOM is the CLO 3.0.9 Operation Limit Condition, concerning to unavailability of barriers, the corresponding analysis that includes deterministic and probabilistic considerations and it is superficially discussed their eventual application to the Laguna Verde Nucleo electric Central (CNLV). The impact in the risk of the proposed changes to the Operation Technical Specification (ETO) it was evaluated following a treatment of three roads recommended by the regulatory guide RG 1.177. It consisted of a simplified analysis of demarcation of the consequent risk with the lack of specific models of risk for this case on each power station, which don't include models of flaw of such passive structures as they are these barriers. Together with the results of the risk evaluation, it is also evaluated the impact on the defense in depth of adding the CLO 3.0.9 proposal to the ETO. With base in the integrated evaluation it was concluded that the change proposed to ETO carries insignificant increases of risk. Certainly, this conclusion is certain without considering any credit for the removal of undesirable potential consequences associated with the current conservative treatment of barriers. With the purpose of to identify and to justify the late times to enter to the actions corresponding to the supported equipment associated with the unavailable barriers, it was presented a change proposal with an analysis informed in risk using Probabilistic Risk Analysis methods (APR), combined with deterministic arguments and of defense in depth. The proposal of the licensees includes the NEI 04-08 guide providing detailed guide on the evaluation and handling of risk associated with the unavailability barriers, the above mentioned according to the 1.174 and 1.177 Regulatory guides.

  1. 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

    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.

    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

  3. The simplest possible bouncing quantum cosmological model

    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.

    Based on metatheoretical considerations, this paper discusses which kinds of traffic forecasts are possible and which kinds are impossible to make with any reasonable degree of accuracy. It will be argued on ontological and epistemological grounds that it is inherently impossible to make exact...... predictions about the magnitude of the ‘general’ traffic growth 20-30 years ahead, since many of the influencing factors depend on inherently unpredictable geopolitical trajectories as well as contested political decision-making. Due to the context-dependency of each particular planning situation, it is also...... hardly possible to make exact, quantitative predictions about the impact of implementing a specific infrastructure project, compared to ‘doing nothing’. Instead of relying on traffic model simulations as the general forecasting and assessment tool in transport planning, we propose to separate the so...

  5. How is an absolute democracy possible?

    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.

    Full Text Available In this article, our main intention is to highlight the fact that the probable links between probability and possibility which were established by different authors at different point of time on the basis of some well known consistency principles cannot provide the desired result. That is why the paper discussed some prominent works for transformations between probability and possibility and finally aimed to suggest a new principle because none of the existing principles because none of them found the unique transformation. The new consistency principle which is suggested hereby would in turn replace all others that exist in the literature references by providing a reliable estimate of consistency between the two.Furthermore some properties of entropy of fuzzy numbers are also presented in this article.

    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).

    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.

  5. Kauffman's adjacent possible in word order evolution

    Ferrer-i-Cancho, Ramon

    2015-01-01

    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...

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.

    The use of Unmanned Aerial Vehicles (UAVs) for surveying is now widespread and operational for several applications - quarry monitoring, archeological site surveys, forest management and 3D modeling for buildings, for instance. UAV is increasingly used by land surveyors especially for those kinds of projects. It is still ambiguous whether UAV can be applicable for smaller sites and property division. Therefore, the objective of this research is to extract a vectorized plan utilizing a UAV for a small site and investigate the possibility of an official land surveyor exploiting and certificating it. To do that, two plans were created, one using a UAV and another utilizing classical land surveyor instruments (Total Station). A comparison was conducted between the two plans to evaluate the accuracy of the UAV technique compared to the classical one. Moreover, other parameters were also considered such as execution time and the surface covered. The main problems associated with using a UAV are the level of precision and the visualization of the whole area. The results indicated that the precision is quite satisfactory with a maximum error of 1.0 cm on ground control points, and 4 cm for the rest of the model. On the other hand, the results showed that it is not possible to represent the whole area of interest utilizing a UAV, due to vegetation.

  13. 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

    Full Text Available [b]Introduction and objective[/b]. [i]Bacillus anthracis[/i] is one of biological agents which may be used in bioterrorism attacks. The aim of this study a review of the new treatment possibilities of anthrax, with particular emphasis on the treatment of pulmonary anthrax. [b]Abbreviated description of the state of knowledge[/b]. Pulmonary anthrax, as the most dangerous clinical form of the disease, is also extremely difficult to treat. Recently, considerable progress in finding new drugs and suitable therapy for anthrax has been achieved, for example, new antibiotics worth to mentioning, levofloxacin, daptomycin, gatifloxacin and dalbavancin. However, alternative therapeutic options should also be considered, among them the antimicrobial peptides, characterized by lack of inducible mechanisms of pathogen resistance. Very promising research considers bacteriophages lytic enzymes against selected bacteria species, including antibiotic-resistant strains. [b]Results[/b]. Interesting results were obtained using monoclonal antibodies: raxibacumab, cAb29 or cocktails of antibodies. The application of CpG oligodeoxynucleotides to boost the immune response elicited by Anthrax Vaccine Adsorbed and CMG2 protein complexes, also produced satisfying therapy results. Furthermore, the IFN-α and IFN-β, PA-dominant negative mutant, human inter-alpha inhibitor proteins and LF inhibitors in combination with ciprofloxacin, also showed very promising results. [b]Conclusions[/b]. Recently, progress has been achieved in inhalation anthrax treatment. The most promising new possibilities include: new antibiotics, peptides and bacteriophages enzymes, monoclonal antibodies, antigen PA mutants, and inter alpha inhibitors applications. In the case of the possibility of bioterrorist attacks, the examination of inhalation anthrax treatment should be intensively continued.

    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.

  18. Possibilities of Laser Processing of Paper Materials

    Science.gov (United States)

    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.

  19. Toward a possible next geomagnetic critical transition?

    2014-05-01

    The geomagnetic field is subject to possible reversals or excursions of polarity during its temporal evolution. Considering the characteristics of the recent geomagnetic field, 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 that are really global. The South Atlantic Anomaly (SAA) is a great depression of the geomagnetic field strength at the Earth's surface, caused by a reverse magnetic flux in the terrestrial outer core. In analogy with critical point phenomena characterized by some cumulative quantity, we fit the surface extent of this anomaly over the last 400 yr with power law 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 recently been 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 by 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 the 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.

    The geomagnetic field is subject to possible reversals or excursions of polarity during its temporal evolution. Considering that: (a) in the last 83 million yr the typical average time between one reversal and the next (the so-called chron) is around 400 000 yr, (b) the last reversal occurred around 780 000 yr ago, (c) more excursions (rapid changes in 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 that are really global.

    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...

    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

    This report describes a 5-year-old girl, mildly mentally retarded, with the following characteristics: macrocephaly; severe obesity; ocular abnormalities (right optic disk coloboma and left choroidal coloboma); short stature; and recurvation of the femur. The case is sporadic with no consanguinity between the parents. The condition was diagnosed tentatively as MOMO syndrome (Macrosomia, Obesity, Macrocephaly, and Ocular Abnormalities) (MIM, 157980), because of the presence of short stature, in contrast with the large stature of the only two previously described cases. It is the third possible example of this rare syndrome to be described in the literature, with some new clinical findings presented.

    1978-01-01

    Statistical correlations between anomalous solar activity (as denoted by large solar flares, active plages, and interplanetary magnetic sector boundaries) and the circulation of the troposphere are reviewed. Two indices (measuring atmospheric vorticity and mean zonal geostrophic flow in the northern hemisphere) are analyzed in an effort to reveal possible sun-weather relationships. The result of this analysis provides no additional statistical evidence for a connection between solar activity and the weather. Finally, physical mechanisms that have been suggested to explain the claimed correlations are discussed.

    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.

    It was proved in the previous work that there must be a maximal possible accretion rate Mmax for a slim disk. Here we discuss how the value of Mmax depends on the two fundamental parameters of the disk,namely the mass of the central black hole M and the viscosity parameter α. It is shown that Mmax increases with decreasing α,but is almost independent of M if Mmax is measured by the Eddington accretion rate MEdd ,which is in turn proportional to M.

    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.

    Named Data Networking is a novel networking architecture which places emphasis on the naming and signing of data. Once so named, the location of data sources becomes less important and the emphasis moves from host to host transfers to pulling data from the network. Furthermore data are cached en route to their destination. We believe this approach has interesting possibilities for High Energy Physics (HEP) and report on work we have done in this area including the development of a scalable repository, a ROOT plugin and a small local testbed, the submission of jobs to a grid cluster and some ideas on an authentication system for LHC VOs.

    We have considered as a theoretical possibility for the development of a nanobiochip the operation principle of which is based on measuring conductance in single-stranded and double-stranded DNA. Calculations have demonstrated that in the majority of cases the conductance of double-stranded nucleotides considerably exceeds that of single-stranded ones. The results obtained are in agreement with recent experiments on measuring the oligonucleotide conductance. It has been shown that an electronic biochip containing 11 nucleotide pairs will recognize approximately 97% sequences. It has also been demonstrated that the percentage of identifiable sequences will grow with the sequence length.

    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

Furthermore new herbicide strategies were tested on efficacy and selectivity in soybeans. The use of imazamox was very selective and showed a relative broad spectrum of controlled weed species. However, efficacy of imazamox must be supported by a pre-emergence treatment and in most cases by a tank mix partner. For example cleavers (Galium aparine can not be controlled by imazamox. Tankmixtures of imazamox and bentazon indicated an antagonism. Efficacy to some weed species was reduced compared to solo application. The low dose concept – three applications of low doses at cotyledon stage of weeds led to some success. However, these strategies must be further investigated, before they can be recommended to commercial farming practice. All herbicide strategies tested showed some surviving weed species. This indicates that choice of herbicides, dose rates and application strategies must be done very careful and site specific.

    Full Text Available The authors deal with a question, which is hard to answer considering the context of the future of the social evolution. The authors suppose that one should ask rather about overcoming the current wave of individualism than about overcoming the current form of capitalism. Individualism dismantles any society and it is necessary to react by building stable dual relationships. It highlights the key role of a family. Collectivism, as well as individualism, are not able to create any kind of social structure and lead the society into the liquid of chaos or into the motionless totality. It states that the economic security of various societies is to certain extent affected by all possible production factors and that the reason of the success of their functioning is a balance between power, wealth and public support. It points out that it is necessary to keep a couple and its relationship as a basic element in theory as well as in practice. In legitimate cases of a production practise, it is possible to consider the human individual as the element. It condemns inhumane artificial terms such as “homo economicus”, human resources or human capital. In the conclusions, the authors appeal to restore humanity in society by the contribution of each individual and his interpersonal relationships.

  3. Ground as a possible heat pump source

    Heat pumps are devices that can increase the thermal level of heat taken from an available source. Their performances are usually very sensible to the temperatures. This is the reason why sources different from the outside air are welcome, since that source is thermally unfavourable. The ground is a possible very favourable source: temperature variations are damped in the ground so much the more deeper one descends. The variations are also delayed, so that in the coldest period one can find equality very good thermal levels. The two main used systems are: horizontal tubes at a depth between 0.8 and 1.5m and vertical tubes. This last technology has gained an increasing popularity with depths which are sometimes deeper than 100m. It interests a large volume of ground with a comparatively small surface area. It is a technology already widespread in Switzerland (where more than 15.000 ground heat pumps were installed in these years), Germany and Austria. It could be a very favourable technology also in Italy and other mediterranean countries both for the presence of good thermal levels underground with excellent characteristics of heat exchange and for the possible use of the ground as a suitable summer thermal sink.

Pyrethrum is not a traditionalcrop in Slovakia but prospects have opened up for its cultivation. The high yields andquality of some suitable pyrethrum ecotypes provide the grounds for effective field productionunder favorable conditions. Pyrethrum yielding 1.275 t of dried flowers per hectareand having at least 1.5% pyrethrum content can be a profitable and highly lucrativecrop with an economic result ranging from 413 to 1071 € per ha. A SWOT analysisrevealed that pyrethrum production in Slovakia could take a course of an offensivestrategy. However, intensive production of this commodity needs further development.Prospects for this non-traditional crop in Slovakia are also promising in terms of developmentof farming systems in which plant protection products of botanical origin wouldbe welcome. Improved processing and stabilization of extract would further increasethe possibilities.

    Full Text Available Green tea is a popular drink, especially in Asian countries, although its popularity continues to spread across the globe. The health benefits of green tea, derived from the leaves of the Camellia sinensis plant, have been studied for many years. Fairly recently, researchers have begun to look at the possibility of using green tea in antimicrobial therapy, and the potential prevention of infections. The particular properties of catechins found in the tea have shown promise for having antimicrobial effects. There are four main catechins (polyphenols found in green tea: (--epicatechin (EC, (--epicatechin-3-gallate (ECG, (--epigallocatechin (EGC, and (--epigallocatechin-3-gallate (EGCG. Three of these, ECG, EGC, and EGCG have been shown to have antimicrobial effects against a variety of organisms. These catechins have exhibited a variety of antimicrobial mechanisms. The results of studies on the antimicrobial effects of green tea have shown that the potential for preventive and therapeutic purposes is present. Further data collection on studies performed with human consumption during the course of infections, and studies on the occurrence of infections in populations that consume regular amounts of green tea will be necessary to complete the picture of its antimicrobial possibilities.

  6. Cognitive sciences and psychoanalysis: a possible convergence.

    Science.gov (United States)

    Imbasciati, Antonio

    2003-01-01

    This paper compares the psychoanalytic description of inner experience with that of the cognitive sciences, which see it in terms of information processing. The two observational standpoints relate to the same mental events. The author considers the possibility of bringing the two descriptions into line with each other and of their mutual translation. The "information" processed in the deep, unconscious, affective, internal experience of a relational context must be identified. This may be possible if a general theory of mental functioning that allows for the data of psychoanalytic observation in terms of semantics, memory, and communication can be formulated. The author examines the theoretical tradition of psychoanalysis, and draws attention to the uncertainties to which Freud's metapsychology gives rise. The energy/drive theory was not only descriptive and clinical in nature, but also had explanatory value, which put psychoanalysis in contact with the other mental sciences of the time. This explanatory value is no longer valid today, and psychoanalytic theories since Freud seem to have disregarded the aspect of "explanation," leaving a theoretical void that has isolated psychoanalysis from the other sciences of the mind. The author contends that object theories may be an appropriate starting point for the exploration of experience in terms of learning processes and of memory traces, and suggests a psychoanalytic cognitivism, coupled with a personal theory to explain the development of the mind.

We focus on such cases of use of the sequence of tenses where it is possible to apply a “double-access interpretation”, i. e. which allows the possibility of choosing between reference points: with the actual time (the moment of speech or with the main clause. This double interpretation is to be found in all three types of time relationships: simultaneousness, priority and posteriority. Some pairs differ semantically; others are used according to the preferences of the speaker with no change of meaning. Most examples are subordinate noun clauses, nonetheless we included examples of other types of clauses as well (e.g. relative, reason clauses. We also analyze the problem of the sequence of tenses where the main verb is in the conditional tense.

    Full Text Available The article describes an intervention research conducted in a city of southern Brazil with users of alcohol and other drugs considered "nonadherent" to the treatment offered in psychosocial care network in the region. Sustaining an inclusive approach and anti-prohibitionist, the study identify the paths taken by drug users in the territory in order to identify "nodes" of the network (rituals, strategies, services, affections. This can indicate a possible Care Clinic based on affection and bond. It is discussed the polarization of the political debate about drugs. It was made a bet on Harm Reduction as a guideline care from the perspective of overcoming the resentment commonly impregnated in the practices and discourses from the area. Among the results was possible to identify the collective production of a rap music in the middle of the investigative process, this "gives another tone" to the experiences and positions of the patients, pointing to the creation of new existential territories as an alternative to public policies committed with health promotion.

  9. Broadcasting of quantum correlations: Possibilities and impossibilities

    In this work, we extensively study the problem of broadcasting of quantum correlations (QCs). This includes broadcasting of quantum entanglement as well as correlations that go beyond the notion of entanglement (QCsbE). It is quite well known from the "no-broadcasting theorem" that perfect broadcasting of QCs is not possible. However, it does not rule out the possibility of partial broadcasting of QCs where we can get lesser correlated states from a given correlated state. In order to have a holistic view of broadcasting, we investigate this problem by starting with a most general representation of two qubit mixed states in terms of the Bloch vectors. As a cloning transformation we have used universal symmetric optimal Buzek-Hillery (BH) cloner both locally and nonlocally. Unlike entanglement, we find that it is impossible to broadcast QCsbE optimally. Lastly, we generalize these results for any symmetric or asymmetric cloning machines as well. This result brings out a fundamental difference between the correlations defined from the perspective of entanglement and the correlations measure which claims to go beyond entanglement.

  10. [Insulin resistance - its causes and therapy possibilities].

    Pelikánová, Terezie

    2014-09-01

    Insulin resistance (IR) is defined as a condition where normal plasma free insuconcentrations induce a reduced response of the body. In the narrower sense we understand IR as the impairment of insulin action in the target structure which may arise at any level of the insulin signalling cascade. In the clinical conditions we usually define it as the impairment of insulin action in glucose metabolism, although it is true that the impairment may concern different effects of insulin and different cell structures. The characteristic feature of IR linked to the metabolic syndrome or Type 2 diabetes is defective signalling which affects PI3-kinase branch of insulin signalling cascade. Other insulin actions depending on the signalling through the Ras complex and MAP-kinase, may not be affected. Due to compensatory hyperinsulinemia they may be even increased. The article summarizes some recent findings regarding the structure and regulation of insulin signalling cascade and analyses selected primary and secondary causes of IR which include genetic and epigenetic factors, the microRNA regulation role, metabolic, humoral and immunological factors. The detailed knowledge of the causes of IR opens possibilities of its rational treatment. This is currently based on the treatment of curable causes of IR, i.e. consistent compensation of diabetes, weight reduction, regimen arrangements (diet, physical activity), re-assessment of the need to use corticosteroids in therapy, treatment of coexisting conditions and possibly administration of metformin or pioglitazone.Key words: cytokines - insulin resistance - insulin signalling cascade.

    Full Text Available Food is a significant aspect of the tourist’s experience of a destination. While the term “wine and food tourism ” is too often addressed only to the taste of the product, the more aseptic definition of “food tourism” wants to focus the attention also on the health properties of local products. Healthy eating is not about strict nutrition philosophies, staying unrealistically thin, or depriving ourselves of the foods we love. Rather, it is about feeling great, having more energy, stabilizing our mood, and keeping ourselves as healthy as possible, all of which can be achieved by learning some nutrition basics and using them in a way that works for us. We can expand our range of healthy food choices and learn how to plan ahead to create and maintain a tasty, healthy diet. Not only the psychological, but also the physical benefits of tourism appear to have gained increasing importance and healthy nutrition represents one of the most important determinants. Food tourism can be considered a potential benefit for human health.Understanding tourists’ needs and wants in terms of healthy food consumption is of paramount importance to hospitality businesses. Food, tourism and health could really be a possible synergy.

  12. Irradiation genetics - possibilities and achievments in wheat

    International Nuclear Information System (INIS)

    Variation in mutability was found in common wheat cultivars when inducing mutations. Mutants were obtained, distinguished from the initial cultivars by a number of features valuable for breeding: lower stem, higher earliness, greater cold and winter hardiness, more productive ears, higher resistance to diseases, etc. Irradiation of seed of F intervarietal hybrids was more effective than that of F1 as regards diversity and mutability of the hybrid population and still more effective in comparison with irradiation of seed from the initial parental cultivars. The possibilities are pointed out of enhancing individual gene mutability and recombinations and translocations by means of irradiation of hybrid seed. Thus, the possibilities are increased of obtaining a wider gamut of mutants attaining even characters distinguishing them from the initial species. Faster consolidation of new forms was observed in induced mutations in the hybrids than in their parental cultivars. Valuable mutant lines and culvars were obtained having higher ear and plant productivity. It is recommended to use induction of mutants in multiple intervarietal hybrids in F2. (author)

  13. The possibility of life proliferation from Enceladus

    Science.gov (United States)

    Czechowski, Leszek

    2016-07-01

    Enceladus is a medium sized icy satellite (MIS) of Saturn. MIS are built of mixtures of rocks and ices. According to [1]: "For life to have emerged […] on the early Earth, a sustained source of chemically transducible energy was essential. The serpentinization process is emerging as an increasingly likely source of that energy" (see also [2]). We consider here conditions for origin of life in the early Enceladus and later proliferation of the life. Mass of serpentinite: The serpentinization on the Earth is often considered with hydrothermal activity in neovolcanic zones along mid-oceanic spreading centers. However, only in small part the hydrothermal activity really occurs. A simple calculations (e.g. [3]) indicate that mass fraction of silicates in Enceladus is ~0.646, hence the total mass of its silicate is ~6.97 10^1^9 kg. [4] considered the process of differentiation and core forming in Enceladus. He found that the result of differentiation is a relatively cold core of loosely packed grains with water between them. The entire core of Enceladus was probably permeable. This could lead to formation of extensive hydrothermal convective systems. It indicates that total mass of serpententinized silicate in Enceladus could be larger than on the Earth. The evolution of temperature in the Enceladus interior for the first a few hundreds Myr is given in [4]. He found that the temperature allows for existing the life even in the center of the satellite. It is possible that for hundreds of Myr the conditions in Enceladus were more favorable for origin of life than on the Earth. Proliferation of life: The low gravity of the Enceladus and its volcanic activity make transport possible. Note that the low temperature of plumes from active region of Enceladus does not kill the organisms. The primitive bacteria could leave the Enceladus with volcanic jets in the same way as particles of the E ring. Other mechanisms could transport particles to terrestrial planets. Therefore it

TrindadeBayardo Torres; Clovis Wannmacher; Denise Macedo  Teaching Offers Many Possibilities Denise Vaz Macedo Biochemistry Department, Biology Institute, Unicamp, Campinas, Brazil.   In the last years my research lines are maintained exclusively through my biochemistry teaching activities at graduation and specialization course (360h. The teaching methodology used was developed over these 20 years into the classroom research. It is based on five practical activities carried out at the initial moment by the students themselves, who monitor the effects of different physical activity situations through the measurement of some plasma metabolites on point of care devices. After instructions the students perform the exercises collects and tabulate the data generated and document all the doubts arising. The educational goal right now is to show that the theory related to muscle contraction, the ATP-producing metabolic pathways is linked to their profession. At adequate moments each group presents to the whole class the practical activity carried out, the data and the doubts produced. After a fully discussion the students are able to relate the data to the studied theory. Also the initial doubts are clarified. A questionnaire applied before and after the discipline indicates the learning effectiveness of this method. Some other results: the students who have demonstrated special interest in the classroom normally join into de lab. Simultaneously they are also prepared for the teaching activity. The demand of specialization course is greater than the supply. The financial resources generated are expressive and administered by the University Foundation. They are fully applied to purchase permanent and consumption materials and for the payment of eventual scholarships for lab researchers. The publication in indexed journals has been constant and regular, and the obtained experimental results always return to the

  15. Detection of coolant blockages: problems and possibilities

    International Nuclear Information System (INIS)

    A semi-empirical model is developed correlating a wide range of experimental data on peak wake temperatures for subassembly blockages; it is predicted that boiling could be produced at a corner blockage of 10 percent flow area in a 325 pin subassembly. An assessment of the possible consequences of local boiling suggests that the margin to propagation may be small, particularly in the presence of fission gas release, leading to a requirement for early detection systems. A continuing theoretical and experimental programme to investigate the temperature noise technique for blockage detection is reported. It is concluded that blockages appreciably smaller than those predicted to produce boiling should be detectable against a background noise level due to subassembly power tilts; considerable statistical certainty would be obtained with a 5 second detection time, giving protection against rapidly developing incidents. The use of wire wrapped fuel pins would raise the detection threshold by a factor approximately 2 to 3 in blockage area

    2012-01-01

    Music is an important part of young people's lives. In this article, we attempt to answer two questions on the links between music et suicide. First, we examine if certain types of music favor suicidal process (ideation and acting out); and, secondly, we examine if music can constitute a tool to reduce the risk of suicide. Several factors possibly involved in links between musical preferences and the suicidal process are developed: the Velten effect and the musical mood induction procedure, the identification and the learning by imitation, the media influence as well as the individual characteristics. A multifactor approach is necessary to understand the complex and birectional links that unite musical preferences and suicide risk. PMID:23666285

    Crane, Jacquelyn N

    2009-01-01

    Numerous sound scientific studies (cross-sectional and longitudinal) have found a positive correlation between religion and physical and mental health. In particular, there is evidence that demonstrates that religion helps cancer patients better adjust to and cope with their disease, at least psychologically. However, some research suggests that mediating factors associated with religion may explain the positive effects of religion on health. This article argues that even if this is the case, there is still intrinsic value to religion in that the mediators themselves are strongly connected to religion, and therefore religion is important to the patient in terms of coping, support, hope, and meaning. This has possible important implications for clinical practice.

  18. Possible interrelations among chemical freezeout conditions

    Tawfik, A; Habashy, D M; Mohamed, M T; Abbas, E

    2016-01-01

    At thermal equilibrium, different chemical freezeout conditions have been proposed so far. They have an ultimate aim of proposing a universal description for the chemical freezeout parameters ($T_{ch}$ and $\\mu_b$), which are to be extracted from the statistical fitting of different particle ratios measured at various collision energies with calculations from thermal models. A systematic comparison between these conditions is presented. The physical meaning of each of them and their sensitivity to the hadron mass cuts are discussed. Based on availability, some of them are compared with recent lattice calculations. We found that most of these conditions are thermodynamically equivalent, especially at small baryon chemical potential. We propose that further crucial consistency tests should be performed at low energies. The fireball thermodynamics is another way of guessing conditions describing the chemical freezeout parameters extracted from high-energy experiments. We endorse the possibility that the various ...

  19. Superbradyons and some possible dark matter signatures

    CERN Document Server

    Gonzalez-Mestres, Luis

    2009-01-01

    Superluminal preons (superbradyons) with a critical speed in vacuum much larger than the speed of light would, if they exist, play a fundamental role as constituents of the physical vacuum. If they are present as free particles in our Universe, they would spontaneously decay by emitting standard particles until they reach a speed equal or close to that of light. They would then form a cosmological sea where the relation between inertial and gravitational masses would differ from conventional Physics. Superbradyons may be at the origin of cosmological and astrophysical phenomena usually associated to dark matter and dark energy. Then, superbradyon spontaneous decays and similar interactions would be candidates to explain data on electron and positron abundances (PAMELA, ATIC, Fermi LAT, HESS, PPB-BETS) considered as possible dark matter signatures.

  20. Is It Possible to Predict Strong Earthquakes?

    CERN Document Server

    Polyakov, Yuriy S; Solovyeva, Anna B; Timashev, Serge F

    2015-01-01

    The possibility of earthquake prediction is one of the key open questions in modern geophysics. We propose an approach based on the analysis of common short-term candidate precursors (2 weeks to 3 months prior to strong earthquake) with the subsequent processing of brain activity signals generated in specific types of rats (kept in laboratory settings) who reportedly sense an impending earthquake few days prior to the event. We illustrate the identification of short-term precursors using the groundwater sodium-ion concentration data in the time frame from 2010 to 2014 (a major earthquake occurred on February 28, 2013), recorded at two different sites in the south-eastern part of the Kamchatka peninsula, Russia. The candidate precursors are observed as synchronized peaks in the nonstationarity factors, introduced within the flicker-noise spectroscopy framework for signal processing, for the high-frequency component of both time series. These peaks correspond to the local reorganizations of the underlying geoph...

  1. Possibilities of computer tomography in multiple sclerosis

    International Nuclear Information System (INIS)

    Computer tomography was performed in 41 patients with multiple sclerosis, the average age of patients being 40.8 years. Native examinations were made of 17 patients, examinations with contrast medium of 19, both methods were used in the examination of 5 patients. In 26 patients, i.e. in almost two-thirds, cerebral atrophy was found, in 11 of a severe type. In 9 patients atrophy affected only the hemispheres, in 16 also the stem and cerebellum. The stem and cerebellum only were affected in 1 patient. Hypodense foci were found in 21 patients, i.e. more than half of those examined. In 9 there were multiple foci. In most of the 19 examined patients the hypodense changes were in the hemispheres and only in 2 in the cerebellum and brain stem. No hyperdense changes were detected. The value and possibilities are discussed of examinations by computer tomography multiple sclerosis. (author)

  2. Quantitative Information Flow - Verification Hardness and Possibilities

    CERN Document Server

    Yasuoka, Hirotoshi

    2010-01-01

    Researchers have proposed formal definitions of quantitative information flow based on information theoretic notions such as the Shannon entropy, the min entropy, the guessing entropy, and channel capacity. This paper investigates the hardness and possibilities of precisely checking and inferring quantitative information flow according to such definitions. We prove that, even for just comparing two programs on which has the larger flow, none of the definitions is a k-safety property for any k, and therefore is not amenable to the self-composition technique that has been successfully applied to precisely checking non-interference. We also show a complexity theoretic gap with non-interference by proving that, for loop-free boolean programs whose non-interference is coNP-complete, the comparison problem is #P-hard for all of the definitions. For positive results, we show that universally quantifying the distribution in the comparison problem, that is, comparing two programs according to the entropy based definit...

  3. The prize - what's possible?

    Weber, K.J.

    1999-05-01

    Recovery factors for comparable reservoirs are often from 10 to 20% higher in the USA than elsewhere. The reason is the relatively low cost of drilling and work-over combined with the high revenue per barrel for the producers in the States. This implies that elsewhere the scope for additional recovery will frequently be of the same order as the noted differences. Another motivation for re-evaluation of older fields is the realisation that irreducible oil saturations measured on core plugs in the past were generally much too high. Consequently, the assumed sweep efficiencies were much too high also, resulting in little incentive for infill drilling or recompletion. A number of factors stimulate the re-evaluation of remaining reserves. Reliable through-casing logging makes the poorly swept zones visible. Detailed structural definition is often possible with 3D seismic. New drilling techniques, like short radius horizontal side tracks, allow economic recompletions of old wells. (Author)

    Grueter, Cyril C; Robbins, Martha M; Ndagijimana, Felix; Stoinski, Tara S

    2013-11-01

    Here we report a description of putative tool use in wild mountain gorillas. At the Dian Fossey Gorilla Fund's Karisoke Research Center in Volcanoes National Park (Rwanda), an adult female was observed using a bamboo culm as a ladder for her offspring. This is one of only a few documented cases of possible tool use in wild gorillas, although tool use behavior is commonly observed in captive gorillas. Although the behavior observed may have been incidental, the present report in combination with previous evidence (Breuer et al., 2005) suggests that tool use in gorillas occurs outside the context of food acquisition and may be directed at overcoming physical obstacles in complex rugged microhabitats such as bamboo forest and swamps.

    Full Text Available This paper deals with the general problem whether and, if so, how far the impact of the digitised learning environment on our traditional distance education will change the way in which teachers teach and learners learn. Are the dramatic innovations a menace to established ways of learning and teaching or are they the panacea to overcome some of the difficulties of our system of higher learning and to solve some of our educational problems caused by the big and far-reaching educational paradigm shift? This paper will not deal with technical or technological achievements in the field of information and communication which are, of course, revolutionary and to be acknowledged and admired. Rather, the digital learning environment will be analysed from a pedagogical point of view in order to find out what exactly are the didactic possibilities and opportunities and what are its foreseeable disadvantages.

    2016-09-01

    Resonant diffraction of synchrotron radiation (SR) is a modern method of studying the structure and properties of condensed matter that can be implemented on third-generation synchrotrons. This method allows one to investigate local properties of media (including magnetic and electronic ones) and observe thermal vibrations, defects, and orbital and charge orderings. A brief review of the advance provided by SR resonant diffraction is presented, and the capabilities of this method for analyzing phase transitions are considered in more detail by the example of potassium dihydrogen phosphate and rubidium dihydrogen phosphate crystals. It is shown that the investigation of the temperature dependence of forbidden reflections not only makes it possible to observe the transition from para- to ferroelectric phase, but also gives information about the proton distribution at hydrogen bonds.

    Full Text Available This paper focuses on the possibilities of ethnic marketing and its ethic connections. The differences found in our face-to-face interviews and analysing questionnaire data will provide opportunities for Hungarian small enterprises. Targeting ethnic groups for marketing purposes results in ethical difficulties. In Hungary, ethnic marketing is yet an inexperienced concept. Based on these ideas the authors examine the ins and outs of using ethnic marketing in case of Germans in Hungary. Consumers with German ethnic attitude really want German products and brands. At the same time, enterprises have to emphasise the products’ “Germanness” and character in a better/stronger way because this can help for better consumer decision making.

  8. Possible Roles of Strigolactones during Leaf Senescence

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Full Text Available Leaf senescence is a complicated developmental process that involves degenerative changes and nutrient recycling. The progress of leaf senescence is controlled by various environmental cues and plant hormones, including ethylene, jasmonic acid, salicylic acid, abscisic acid, cytokinins, and strigolactones. The production of strigolactones is induced in response to nitrogen and phosphorous deficiency. Strigolactones also accelerate leaf senescence and regulate shoot branching and root architecture. Leaf senescence is actively promoted in a nutrient-poor soil environment, and nutrients are transported from old leaves to young tissues and seeds. Strigolactones might act as important signals in response to nutrient levels in the rhizosphere. In this review, we discuss the possible roles of strigolactones during leaf senescence.

    Chakraborty, Sumanta

    2015-01-01

    The discrepancy between observed virial and baryonic mass in galaxy clusters have lead to the missing mass problem. To resolve this, a new, non-baryonic matter field, known as dark matter has been invoked. However, till date no possible constituents of the dark matter components are known. This has led to various models, by modifying gravity at large distances to explain the missing mass problem. The modification to gravity appears very naturally when effective field theory on a lower dimensional manifold, embedded in a higher dimensional spacetime is considered. It has been shown that in a scenario with two lower dimensional manifolds separated by a finite distance is capable to address the missing mass problem, which in turn determines the kinematics of the brane separation.

    We present a preliminary study of 27 microflares observed by Solar X-ray Spectrometer (SOXS) mission during July 2003 to August 2006. We found that all 27 microflares show the Fe-line feature peaking around 6.7 keV, which is an indicator of the presence of coronal plasma temperature ≥ 9 MK. On the other hand, the spectra of microflares showhybrid model of thermal and non-thermal emission, which further supports them as possible sources of coronal heating. Our results based on the analysis show that the energy relapsed by the microflares is good enough for heating of the active corona. We discuss our results in the light of the hybrid model of microflares production.

    2015-12-01

    Full Text Available Fundamentalism is the religious Protestant movement that developed upon the spreading of the “millennium” belief, which belongs to the Christian theo-logy, in the USA towards the end of 19th century. Nowadays the word “funda-mentalism” is used, sometimes explicitly and sometimes implicitly, to refer to Islam as an equivalent of intolerance, pro-violence and fanaticism. This propa-ganda is so great that recognition of Islam by a Muslim raises the risk for him to be qualified as fundamentalist. In this essay, we will interrogate whether it is possible or not to establish a relation between fundamentalism, which is a wes-tern phenomenon, and Islam by examining historical and cultural background of the both.

Sounds like science fiction? Think again.   CERN has teamed up with Spain’s national scientific research centre (CIEMAT) to develop an avant-garde cyclotron to be used for Positron Emission Tomography (PET). “We plan to make a cyclotron that doesn't need an insulated building or ‘vault’: a cyclotron small enough to fit inside a hospital lift,” explains Jose Manuel Perez, who is leading the CIEMAT/CERN collaboration. “It will be the smallest possible medical cyclotron for single patient dose production and will dramatically reduce costs for hospitals.” While PET technology has transformed imaging techniques, many of its medical benefits have remained confined to highly specialised hospitals. “Studies have foun...

    This paper describes the kind of computing resources it may be possible to make available for experiments in high energy physics in the mid and late 1990s. We outline some of the work going on today, particularly at Fermilab's Advanced Computer Program, that projects to the future. We attempt to define areas in which coordinated R and D efforts should prove fruitful to provide for on and off-line computing in the SSC era. Because of extraordinary components anticipated from industry, we can be optimistic even to the level of predicting million VAX equivalent on-line multiprocessor/data acquisition systems for SSC detectors. Managing this scale of computing will require a new approach to large hardware and software systems. 15 refs., 6 figs.

  15. Possibilities for global governance of converging technologies

    International Nuclear Information System (INIS)

    The convergence of nanotechnology, modern biology, the digital revolution and cognitive sciences will bring about tremendous improvements in transformative tools, generate new products and services, enable opportunities to meet and enhance human potential and social achievements, and in time reshape societal relationships. This paper focuses on the progress made in governance of such converging, emerging technologies and suggests possibilities for a global approach. Specifically, this paper suggests creating a multidisciplinary forum or a consultative coordinating group with members from various countries to address globally governance of converging, emerging technologies. The proposed framework for governance of converging technologies calls for four key functions: supporting the transformative impact of the new technologies; advancing responsible development that includes health, safety and ethical concerns; encouraging national and global partnerships; and establishing commitments to long-term planning and investments centered on human development. Principles of good governance guiding these functions include participation of all those who are forging or affected by the new technologies, transparency of governance strategies, responsibility of each participating stakeholder, and effective strategic planning. Introduction and management of converging technologies must be done with respect for immediate concerns, such as privacy, access to medical advancements, and potential human health effects. At the same time, introduction and management should also be done with respect for longer-term concerns, such as preserving human integrity, dignity and welfare. The suggested governance functions apply to four levels of governance: (a) adapting existing regulations and organizations; (b) establishing new programs, regulations and organizations specifically to handle converging technologies; (c) building capacity for addressing these issues into national policies and

  16. The hydrogen society - a national possibility study

    International Nuclear Information System (INIS)

    A national possibility study has been carried out for hydrogen as a future environmentally congenial energy carrier. The investigation has mapped from an international perspective, the existing competence at the research institutions and universities, the Norwegian industrial and business sectors as well as possible technological and marketing activity sectors. The information has been procured mainly through a workshop with about 100 Norwegian participants and 3 invited foreign lecturers. An internal workshop has also been arranged in order to discuss the format and content of the report. This study has shown that Norway has special conditions for business development with respect to hydrogen as energy carrier, particularly as a gas nation, but also based on the existing competence within the industry and at the universities and research institutes within hydrogen production and electrolysis. A future business development within the field would depend on the public research contribution, however, the potentials are large. The Norwegian research and development in the field should concentrate the efforts with the recommendation in the report in mind. The recommendations may be summarised as follows: Intensive research and development. Short term (10 years): The production of hydrogen from natural gas with CO2 separation, development of PEM fuel cell systems. Long term (30 years): Focus on the production through water electrolysis, storage of hydrogen carriers, hydrogen relevant materials research. Moderate research and development. Short term (10 years): Integrated systems, storage with fluid hydrogen carriers, combustion technology for H2 mixtures, system solutions. Long term (30 years): Production of biophotolysis, solid oxide fuel cells (SOFC). Technological monitoring. Short term (10 years): Storage as condensed gas. Long term (30 years): Production through photoelectolysis, gasification of biomass

    Full Text Available Dental caries is a multifactorial disease that affects most populations throughout the world and it is still the primary cause of oral pain and tooth loss. The occlusal surfaces of posterior teeth are the most vulnerable sites for dental caries due to their anatomy. Therefore, the aim of the following article is to summarize current knowledge on occlusal caries development and the possibilities of its prevention. Although the overall caries rate today has fallen for populations in industrialized countries, the rate of occlusal surface caries has not decreased. This may be explained with fact that topically applied fluorides and their mode of action prevent caries better on smooth than on occlusal surfaces. As we know, tooth decay of first permanent molars causes a great deal of different short and long term difficulties for patients. Therefore, there is a continuous need for implementation of programs for caries prevention in permanent teeth. Nowadays, we like to treat our patients by minimally invasive methods. A very important step in our effective preventive treatment is sealing pits and fissures as a cornerstone of occlusal caries management. Reliable assessment of caries activity is also very important for defining treatment needs and plans. A very important decision, which should be made during occlusal caries management, is the selection of restorative material according to the treatment plan. Conclusion. Current possibilities in occlusal caries prevention and management are very effective. Therefore, dentists today do not have any excuse for avoiding the philosophy of Minimally Invasive Dentistry, especially when we talk about caries management of occlusal surfaces in permanent molars.

  18. Possible uses of satellite remote sensing in agrometeorology

    International Nuclear Information System (INIS)

    Remote sensing offers new possibilities in agrometeorology. Meteorological satellites (which have good revisit capability but low spatial resolution) and earth observation satellites (which have good spatial resolution but poor revisit capability) give complementary information on crop growth conditions and on the biological status of plants. Thermal infrared data can be used to map local climates, to estimate water balance at the scale of a small region and to determine the extent and the seriousness of damage caused by major climatic accidents (frost, drought). Visible near, near and middle infrared data are well adapted to crop identification and monitoring, biomass estimation and yield forecasting. The combination of information given by these 2 types of satellites should in future provide better knowledge and better control of agricultural production. However the application of such techniques may be limited by the cloud cover

  19. Reinventing the Possibilities: Academic Literacy and New Media

    Full Text Available This webtext demonstrates the possibilities of using new media to teach students critical literacy skills applicable to the 21st century. It is a manifesto for what the authors think writing scholars should be teaching in general-education "writing" classes like first-year composition. In order to answer the question of what we should teach, we have to ask what kinds of academic literacy, if any, we value. The authors argue here that rhetorical theory is a productive way to theorize how meaning is made among new media texts, their designers, and their readers. They use the Ancient Greek concepts of topoi and commonplace to explain how designers and readers enter into a space of negotiated meaning-making when converging upon new media texts. That negotiated space offers a new-media space for learning critical literacies by means other than research papers. As examples, they discuss two student texts and the literacies they demonstrate.

    Full Text Available The paper presents a semi-industrial reactor designed for utilisation of waste moulds and cores made of thermosetting moulding sands by microwave incinerating. It was found that a possibility exists of effective incinerating residues of this kind waste cores or moulds left after casting. The research evidences that the apparatus permits effective control of the applied microwave heating process. Preliminary tests of microwave heating indicated that incinerating waste moulds and cores made of industrially used moulding sands based on phenolic- formaldehyde resins is an effective method of their utilization. Application of microwave heating for incinerating waste moulds and cores containing synthetic resins as binders guarantees significant and measurable economical benefits resulting from reduced process time.

  1. Highly Accreting Quasars: Sample Definition and Possible Cosmological Implications

    CERN Document Server

    Marziani, Paola

    2014-01-01

    We propose a method to identify quasars radiating closest to the Eddington limit, defining primary and secondary selection criteria in the optical, UV and X-ray spectral range based on the 4D eigenvector 1 formalism. We then show that it is possible to derive a redshift-independent estimate of luminosity for extreme Eddington ratio sources. Using preliminary samples of these sources in three redshift intervals (as well as two mock samples), we test a range of cosmological models. Results are consistent with concordance cosmology but the data are insufficient for deriving strong constraints. Mock samples indicate that application of the method proposed in this paper using dedicated observations would allow to set stringent limits on Omega_M and significant constraints on Omega_Lambda.

    Based on the digital elevation model (DEM), a new model for calculating possible sunshine duration (PSD) is completely described. Using this model, monthly PSD with resolution of 1 km×1 km for the rugged topography of China is calculated. Results suggest that terrain has robust effect on PSD, particularly in winter when a lower sun elevation angle exists. Besides, the proposed model taking the DEM data as the input has an ability to process mass of data and is applicable to satellite image processing platforms or Geographic Information System (GIS). The PSD (in hours) is provided in the same way as other kinds of spatial information and can be employed as basic geographic data for relevant studies as well.

    2015-02-01

    In recent years, the As-Rigid-As-Possible (ARAP) shape deformation and shape interpolation techniques gained popularity, and the ARAP energy was successfully used in other applications as well. We improve the ARAP animation technique in two aspects. First, we introduce a new ARAP-type energy, named SR-ARAP, which has a consistent discretization for surfaces (triangle meshes). The quality of our new surface deformation scheme competes with the quality of the volumetric ARAP deformation (for tetrahedral meshes). Second, we propose a new ARAP shape interpolation method that is superior to prior art also based on the ARAP energy. This method is compatible with our new SR-ARAP energy, as well as with the ARAP volume energy.

    Full Text Available In this trial it is discuss with particular attention the troubles surrounding the teachers and the Education for peace. Currently the teachers in high school education find themselves in an unprecedented situation due to the recent obligatory nature of this education level, the equally recent education reforms and the application of the competency education approach. Formed in many cases for teachers with no pedagogical formation or experience, the staff of high school education faces the institutional requirements with very few elements to be able to satisficed. In this context it began to be introduced the alternative of the Education for peace, but it is necessary to reflect upon the real possibilities of the schools, their authorities, their teachers and their students to accomplish it.

  6. Relational frame theory and Skinner's Verbal Behavior: A possible synthesis.

    2000-01-01

    The current article suggests a possible synthesis of Skinner's (1957) treatment of verbal behavior with the more recent behavioral interpretation of language known as relational frame theory. The rationale for attempting to combine these two approaches is first outlined. Subsequently, each of the verbal operants described by Skinner is examined and subjected to a relational frame analysis. In each case, two types of operants are identified; one based on direct contingencies of reinforcement and the other based on arbitrarily applicable relational responding. The latter operants are labeled verbal because they can be distinguished from other forms of social behavior, and they appear to possess the symbolic or referential qualities often ascribed to human language. By applying relational frame theory to Skinner's verbal operants, we aim to contribute towards the development of a modern behavior-analytic research agenda in human language and cognition.

    Full Text Available 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 study was undertaken to study the effect of long chain cyanoacrylate as an adhesive for intraoral wound closure and also to explore its hemostatic and antibacterial effects. Isoamyl-2-cyanoacrylate (AMCRYLATE was used as the adhesive in the study. In conclusion isoamyl cyanoacrylate can be used for intraoral wound closure, as an alternative to sutures for gluing the mucoperiosteum to bone, for example, after impaction removal, periapical surgeries, and cleft repair. Its hemostatic and antibacterial activity has to be further evaluated.

  8. Automated weed detection in the field - possibilities and limits

    2016-02-01

    Full Text Available Unmanned Aerial Vehicles (UAV have become omnipresent and adequate tools to generate high-resolution spatial data of agricultural cropland. Their implementation into remote sensing approaches of weeds provides suitable applications for a site-specific herbicide management. In general, an increasingly use of innovative technologies gradually leads from agricultural research into the practical application. This requires an evaluation of possibilities and limits of UAV-based remote sensing procedures. While spectrals from UAVs are being used already for mapping needs of nutrient or water, the image supported weed detection is much more complex and at the moment not relevant in practice. In this regard, there is a lack of weed and crop differentiation through spectral analyses and object-based approaches separate different plants not species-specific or are not adapted to morphologic changes of the growth. Moreover, there is a need for alternative positioning techniques without GPS, as it is required for a precise optical imaging analysis at low altitudes. To evaluate the possibilities and limitations of automated weed identification regarding the optical and sampling requirements, flights were carried out with a hexacopter at an altitude of 5 m over agricultural crop land with variable weed patches. The altitude was controlled by the GPS-autopilot. Images were captured at geo-referenced points and the number of different weed species was simultaneously determined by manually counting. The required optical resolution on the ground was estimated by comparing the number of weeds between image analysis on the PC and with the field rating data.

    2002-01-01

    Full Text Available The paper explores the possibilities of using telephone technology in educational process. It is emphasized how valuable audio-teleconference and tutorial teaching are by means of telephone technology but skepticism is also expressed concerning the possibilities of using this type of technology in our educational system. The causes for such skepticism are mostly to be found in our economic conditions, inadequacy of material sources and technical problems i.e. underdeveloped telephone networks. Telephone technology is not suitable for work with a whole class. It is primarily intended for one-to-one teaching, in the USA most often called 'tutorship'. Accordingly, 'telephone tutorship' is the most widespread form of telephone application in the teaching process. When it is being accomplished, a student (user has only to have a telephone at home or that public phone network is operating and he/she can communicate with his/her 'tutor', (teacher. 'A tutor' can be at home and communicate with his/her students or at a local learning center wherefrom he/she can communicate with a student. Students can also be at their local learning center or at home.

  10. Possibility of Replacing the Chorinated Paraffins in Metalworking Fluids

    2013-12-01

    Full Text Available All components that are used for neat oil formulations for metalworking operations belong to group of chemicals that, because of its direct application, can have a big influence on the environment and especially on human health. With time, metalworking operations become more complex and demanding. New materials with various compositions are processed, and they demand metalworking fluids with improved antiwear properties and that provide extreme load-carrying capabilities. Exactly this addition, known as EP additives, that had been until recently based on chlorinated paraffins, are a group of chemicals that need to be replaced as soon as possible with a components that are environmentally acceptable. In this paper, in laboratory conditions, we investigated synthetic polymeric esters, as one of the possible substitute for chlorinated paraffins, in several neat oil formulations, which are used for various metalworking operations. From the above comparative results of analysis results it can be concluded that synthetic polymeric esters can serve like an adequate substitute for metalworking fluids which are designed for easy operations.

    Intraperitoneal (i.p.) administration of the synthetic agonist of the glucagon like peptide-1 (GLP-1) receptor exenatide reduces food intake. Here, we evaluated possible peripheral pathways for this reduction. Exenatide (0.5 μg/kg, i.p.) was given to three, overnight food-deprived, groups of rats: total subdiaphragmatic vagotomy (VGX, severs the vagus nerve), celiaco-mesenteric ganglionectomy (CMGX, severs the splanchnic nerve) and combined VGX/CMGX. Following the injection, meal sizes (MSs) and intermeal intervals (IMIs) were determined for a total of 120 min. We found that exenatide reduced the sizes of the first two meals but failed to prolong the IMI between them, that VGX attenuated the reduction of the first MS, and that VGX, CMGX and combined VGX/CMGX attenuated the reduction of the second MS by exenatide. Therefore, the vagus nerve appears necessary for the reduction of the first MS by exenatide, whereas both nerves appear necessary for the reduction of the second MS by this peptide. PMID:22222610

  12. Possibility in optimization of biological phosphorus removal

    Energy Technology Data Exchange (ETDEWEB)

    Schoenberger, R.

    1989-02-01

    The elimination-efficiency of wastewater treatment plants with biological phosphorus removal is often limited by the following aspects: Low concentrations of organic acids in influent wastewater, hydraulic- and load fluctuations, low anaerobic sludge detention time, transfer of nitrate into the anaerobic zone, phosphorus release in the final clarifier and in sludge treatment units, high effluent suspended solids content. In this context, the following optimization measures seem to be advantageous: 'Activated primary tanks' and 'activated sludge thickeners' are adequate techniques to raise the concentration of organic acids in the wastewater by pre-acidification. Simultaneous acidification takes place in an anaerobic sedimentation basin as realized in the EASC-process (extended anaerobic sludge contact). Below the sludge blanket of an EASC-sedimentation tank, anaerobic conditions can be maintained even in the case of nitrate input. Furthermore, this process is suitable to compensate load- and hydraulic fluctuations of wastewater. To avoid phosphorus release in the final clarifier, it is important to improve sludge settleability. If a low sludge blanket and/or high oxygen concentrations are maintained, phosphorus release in the final clarifier can be limited. Further reduction of total phosphorus is possible with filtration only. Measures against high return flow phosphorus loads are mechanical dewatering of excess sludge and chemical precipitation of digester supernatant.

  13. The possibility of life proliferation from Enceladus

    Czechowski, Leszek

    2016-04-01

    Introduction: Enceladus is a medium-sized icy satellite (MIS) of Saturn. MIS are built of mixtures of rocks and ices. Enceladus with its radius of 250 km is one of the smallest of MIS, however, it is geologically active. According to [1]: "For life to have emerged […] on the early Earth, a sustained source of chemically transducible energy was essential. The serpentinization process is emerging as an increasingly likely source of that energy. Serpentinization of ultramafic crust would have continuously supplied hydrogen, methane, […] to off-ridge alkaline hydrothermal springs that interfaced with the metal-rich carbonic Hadean Ocean" (see also [2]). We consider here conditions for origin of life in early Enceladus and possible proliferation of the life from this satellite to the rest of Solar System. Mass of serpentinite: The serpentinization on the Earth is found in neovolcanic zones along mid-oceanic spreading centers. However, only in small part of them the hydrothermal activity really occurs. After [3] we consider the following reaction: Mg2SiO4 + MgSiO3 + 2H2O -> Mg3Si2O5(OH)4 . This reaction releases 241 000 J per kg of serpentine produced. Simple calculations (e.g. [4]) indicate that mass fraction of silicatesfmas in Enceladus is ˜0.646, hence the total mass of its silicate is ˜6.97 1019 kg. [4] found that the early core in Enceladus was a relatively cold structure built from loosely packed grains with water between them. At that time, there was not mechanism of removing the water. Since rocks are permeable up to the pressure of ˜300 MPa then the entire core of Enceladus was probably permeable for liquids. This could lead to formation of extensive hydrothermal convective systems. T-p conditions in Enceladus: The pressure in the center of Enceladus is ˜2.3 107 Pa that corresponds to pressure on the depth 2300 m in a terrestrial ocean. The evolution of temperature in the Enceladus interior for the first a few hundreds Myr is considered by [4]. If

    Although histamine intolerance (HIT) is not very frequently encountered, it can have serious consequences. Food intolerance is a non allergic hypersensitivity to food that does not include the immune system even though the symptoms are similar to those of IgE-mediated allergic reactions. HIT apparently develops as a result of an impaired diamine oxidase (DAO) activity due to gastrointestinal disease or through DAO inhibition, as well as through a genetic predisposition which was proven in a number of patients. The intake of histamine-rich foods as well as alcohol or drugs which cause either the release of histamine or the blocking of DAO can lead to various disorders in many organs (gastrointestinal system, skin, lungs, cardiovascular system and brain), depending on the expression of histamine receptors. Dermatologic sequels can be rashes, itch, urticaria, angioedema, dermatitis, eczema and even acne, rosacea, psoriasis, and other. Recognizing the symptoms due to HIT is especially important in treating such patients. The significance of HIT in patients with atopic dermatitis in whom the benefit of a low histamine diet has been proven is becoming increasingly understood recently. Because of the possibility of symptoms affecting numerous organs, a detailed history of symptoms following the intake of histamine-rich foods or drugs that interfere with histamine metabolism is essential for making the diagnosis of HIT. Considering that such symptoms can be the result of multiple factors, the existence of HIT is usually underestimated, but considerable expectations are being made from future studies. PMID:23814966

    We propose that several short duration events observed in past stellar occultations by Chiron were produced by rings material. From a reanalysis of the stellar occultation data in the literature we determined two possible orientations of the pole of Chiron's rings, with ecliptic coordinates l=(352+/-10) deg, b=(37+/-10) deg or l=(144+/-10) deg, b=(24+/-10) deg . The mean radius of the rings is (324 +/- 10) km. One can use the rotational lightcurve amplitude of Chiron at different epochs to distinguish between the two solutions for the pole. Both imply lower lightcurve amplitude in 2013 than in 1988, when the rotational lightcurve was first determined. We derived Chiron's rotational lightcurve in 2013 from observations at the 1.23-m CAHA telescope and indeed its amplitude is smaller than in 1988. We also present a rotational lightcurve in 2000 from images taken at CASLEO 2.15-m telescope that is consistent with our predictions. Out of the two poles the l=(144+/-10) deg, b=(24+/-10) deg solution provides a bett...

    Malignant lymphomas are one of the most common malignant tumours occurring in dogs. The basic method of lymphoma diagnosis in human, as well as in canine oncology is histopathology supported by immunohistochemistry. It was suggested that in veterinary medicine excisional biopsy of lymph node and histopathology should be considered only where the cytologic diagnosis is equivocal or needs to be confirmed. There are at least three basic reasons for which cytological examination ought to be accepted as a sufficient and reliable diagnostic method for lymphoma in dogs. Firstly, most dog owners consider the fine-needle biopsy as an acceptable non-harmful method of sample collection. Secondly, an increasing number of studies recommend cytology as an accurate test for diagnosing and subtyping canine lymphoma. Finally, the vast majority of canine lymphoma subtypes belong to 4-5 categories characterized by a typical cytological picture. Immunocytochemical staining of cytological smears gives new diagnostic possibilities, such as detection of markers better characterizing given growth or a potential goal for target therapy in individual cases (for example inhibitors of platelet-derived growth factor).

  17. Vattimo and the Possibilities of Nihilistic Ontology

    Directory of Open Access Journals (Sweden)

    Myroslav Feodosijevič Hryschko

    2010-04-01

    Full Text Available Gianni Vattimo’s “nihilistic ontology” is immediately distinguished by its resolute anti-metaphysics. Thus, instead of what Vattimo construes as the definitive tropes of metaphysics, i.e., temporal permanence, necessity, foundationalism, etc., the possibility of nihilistic ontology must maintain a critical exigency regarding these tropes. According to this imperative, Vattimo seeks to equate nihilistic ontology with a hermeneutic ontology. This text examines this equation, attempting to separate the continuity between nihilism and hermeneutics, according to the latter’s commitment to a variation of anthropocentrism evinced in concepts such as the effectivity of the particular content of a history, which in turn belies a nihilism that has posited history and man as contingent. Rather, what is at stake in a nihilistic ontology, consistent with Vattimo’s reading, is a radically minimal ontology dedicated to the contingency of Being itself, thus excising the privileged ontological status of man that characterizes the hermeneutic ontology, a privileging analogous to the very metaphysical foundationalism that nihilism is to obviate.

    Full Text Available Background. The literature on lingering or “cumulative” effects of multiple concussions is mixed. The purpose of this study was to examine whether athletes with a history of three or more concussions perform more poorly on neuropsychological testing or report more subjective symptoms during a baseline, preseason evaluation. Hypothesis. Athletes reporting three or more past concussions would perform more poorly on preseason neurocognitive testing. Study Design. Case-control study. Methods. An archival database including 786 male athletes who underwent preseason testing with a computerized battery (ImPACT was used to select the participants. Twenty-six athletes, between the ages of 17 and 22 with a history of three or more concussions, were identified. Athletes with no history of concussion were matched, in a case-control fashion, on age, education, self-reported ADHD, school, sport, and, when possible, playing position and self-reported academic problems. Results. The two groups were compared on the four neuropsychological composite scores from ImPACT using multivariate analysis of variance followed by univariate ANOVAs. MANOVA revealed no overall significant effect. Exploratory ANOVAs were conducted using Verbal Memory, Visual Memory, Reaction Time, Processing Speed, and Postconcussion Scale composite scores as dependent variables. There was a significant effect for only the Verbal Memory composite. Conclusions. Although inconclusive, the results suggest that some athletes with multiple concussions could have lingering memory deficits.

    Full Text Available The aim of the investigation was to assess the possibility of glioblastoma differentiation using infrared spectroscopy, proton magnetic resonance spectroscopy and immunohistochemistry. Materials and Methods. 22 patients with glioblastomas and 21 patients with anaplastic astrocytomas were examined. All the patients underwent infrared spectroscopy of blood serum. 16 patients with glioblastomas were examined preoperatively and postoperatively, and in both cases 7 of them underwent proton magnetic resonance spectroscopy of tumors and identical peritumoral areas. All diagnoses were morphologically confirmed, and 10 cases with glioblastomas and 15 cases with anaplastic astrocytomas were confirmed by immunohistochemistry. Results. Glioblastoma differentiation (Grade IV into anaplastic astrocytomas (Grade III was revealed postoperatively, in total glioblastoma resection and confirmed by the findings of infrared spectroscopy in blood serum, proton magnetic resonance spectroscopy of identical peritumoral areas performed preoperatively and postoperatively, as well as by immunohistochemical investigation of peritumoral area. Conclusion. The complex of the techniques applied (infrared spectroscopy, proton magnetic resonance spectroscopy, immunohistochemistry enables to assess how effective and total the surgery was, and if it promoted glioblastoma differentiation postoperatively, and determine how the tumor will develop after the surgery: as glioblastoma — with early continuous tumor growth, or as anaplastic astrocytoma — with the longer recurrence-free period. The findings are in agreement with tissue theory of tumor genesis; and change the understanding of the role and significance of surgical resection of glioblastomas in tumor differentiation.

  1. Obstacles and possibilities in police research

    Directory of Open Access Journals (Sweden)

    Ragnhild Sollund

    2005-09-01

    Full Text Available Drawing on a Norwegian research project investigating the possible existence of police racism, this article explores challenges related to conducting research in such sensitive sites as the police with reference to methodological and institutional obstacles. The project featured participant observation, in-depth interviews with ethnic minority men, and in-depth interviews with police officers and lays the basis for a discussion of the diverging perspectives on police racism held by the police and by members of ethnic minorities. The degree to which research on the police can reveal the  ‘truth’ of policing and thereby contribute to changing police practice is problematised and questions are asked about the extent to which research can contribute to facilitating change within the police that might be of benefit to the relationship between the police and ethnic minorities. A key question raised is whether the existence of a specific police culture, featuring loyalty, a hierarchical organisational structure and the use of discretion may prevent such research methods from revealing ‘true’ data, as well as organisational change. A discussion of problem-oriented policing illustrates some  of the obstacles to implementing changes. The article concludes that the police in Oslo do not demonstrate evidence of institutional racism though there is evidence of derogatory language use and stereotyping where ethnic minorities are stereotyped in homologous ways to other marginalised groups who come into contact with the police such as drug users.

    Telocytes (TCs) are a novel type of interstitial cells which are potentially involved in tissue regeneration and repair (www.telocytes.com). Previously, we documented the presence of TCs in liver. However, the possible roles of TCs in liver regeneration remain unknown. In this study, a murine model of partial hepatectomy (PH) was used to induce liver regeneration. The number of TCs detected by double labelling immunofluorescence methods (CD34/PDGFR-α, CD34/PDGFR-ß and CD34/Vimentin) was significantly increased when a high level of hepatic cell proliferation rate (almost doubled) as shown by 5-ethynyl-2'-deoxyuridine (EdU) immunostaining and Western Blot of Proliferating cell nuclear antigen (PCNA) was found at 48 and 72 hrs post-PH. Meanwhile, the number of CK-19 positive-hepatic stem cells peaked at 72 hrs post-PH, co-ordinating with the same time-point, when the number of TCs was most significantly increased. Taken together, the results indicate a close relationship between TCs and the cells essentially involved in liver regeneration: hepatocytes and stem cells. It remains to be determined how TCs affect hepatocytes proliferation and/or hepatic stem cell differentiation in liver regeneration. Besides intercellular junctions, we may speculate a paracrine effect via ectovesicles.

Dermatologic sequels can be rashes, itch, urticaria, angioedema, dermatitis, eczema and even acne, rosacea, psoriasis, and other. Recognizing the symptoms due to HIT is especially important in treating such patients. The significance of HIT in patients with atopic dermatitis in whom the benefit of a low histamine diet has been proven is becoming increasingly understood recently. Because of the possibility of symptoms affecting numerous organs, a detailed history of symptoms following the intake of histamine-rich foods or drugs that interfere with histamine metabolism is essential for making the diagnosis of HIT. Considering that such symptoms can be the result of multiple factors, the existence of HIT is usually underestimated, but considerable expectations are being made from future studies.

    Full Text Available In Lithuania main part of biodegradable waste (BDW from the municipal waste (MW stream, food waste from coffees and other catering companies are disposed of in landfills. Primary BDW sorting and / or secondary processing within the mechanical-biological treatment (MBT equipment is planned in Waste Management Plants (WMP in all Lithuanian regions. Lithuania has old traditions of BDW management methods, as green waste (GW composting e.g. mulching is one of the most popular, especially in rural areas. Therefore, reinstatement of composting traditions by implementing modern composters (composting bins in the territories of individual households is practically provided by all WMP. Composting of sorted BDW from MW stream and GW from public territories or green areas of companies is one of the useful BDW management methods, because, first of all, a new product – bio-compost is produced and used for agricultural purposes.This paper presents results of the research done in the Institute of Environmental Engineering (APINI of Kaunas Technological University (KTU implementing two projects: Home - composting in individual households of Tauragė region (RECO Baltic 21 Tech (RB21T project and Feasibility analysis of BDW management techniques in KTU (”KTU - Green University” project.

    Uncertainty is an unavoidable component of the estimation of the risk of exposure to soil pollutants. Information regarding parameters that influence the risk of exposure are generally fraught with uncertainty. This uncertainty may have essentially two origins: randomness (due in particular to variability phenomena) and incompleteness (i.e., when information regarding parameter values is simply lacking). The ideal way to address uncertainty due to randomness is to collect data, perform a statistical analysis and identify a probability distribution which accounts for the randomness. When information is incomplete, or statistical data are not available, human experts can supply information on parameter values. Such subjective information can be tainted with various defects (ambiguity, vagueness, imprecision, etc.) and can be represented in various fashions (probability density functions, possibility distributions, uncertainty intervals, etc.). While different types of uncertainty may warrant different models of uncertainty representation, the question arises as to how several modes of representation can be accommodated in the same estimation of risk? This paper provides some clear insight into the fundamental differences between probabilities and possibilities, and the consequences of assuming one or the other when representing uncertainty. This paper presents the so-called 'hybrid' approach (Guyonnet et al., 2003) which combines probability distribution functions (PDF's) and possibility distributions (fuzzy numbers) in the same computation of risk. Because it allows one to take advantage of the 'rich' information provided by the PDF's, while retaining the conservative character of fuzzy calculus to account for those parameters for which a representation by unique PDF's is not justified by the available data, the hybrid method is believed to hold value in terms of consistency with a 'reasonable' application of the

    Emerging information and communication technology is changing medical and psychological practice by enabling the provision of services across time and distance, yet there are significant concerns about these applications. Given the emerging nature of trial evidence in teleneurology, our aim is to provide a narrative review, in order to investigate possible oncoming fields of applications that are very important in healthcare practices delivered to patients affected by neurological diseases. We will focus on the use of Tele-Health in neurological practice, highlighting the potential benefits of applying information and communication technology also to psychosocial and educational aspects of neurological diseases treatment. This work is based on PubMed search, manual search of published abstracts/conference proceedings, and consultation with investigators in neurological disease. We refer also to the broader Tele-Health research concerning mental diseases. Tele-Health has obvious advantages in rural areas, where it improves access to health services, obviating the need for patients and healthcare workers to travel and assuring continuance to healthcare services delivery. Even in urban areas, however, Tele-Health can improve access to health services and to information. It may sometimes also be cheaper than conventional practice, even if there is generally limited knowledge of the cost-effectiveness of Tele-Health services compared to conventional methods of delivering health services.

    2014-01-01

    To address these limitations of optogenetics, here we propose two new methods for optogenetic stimulation. The first is x-optogenetics, which uses visible light-emitting nanophosphors stimulated by focused x-rays. This idea is not new but the application to optogenetics is novel. X-rays can penetrate much more deeply than infrared light and could allow for nerve cell stimulation in any part of the brain. In this paper, we discuss the feasibility and possibilities of such a method by describing the advances in nanomaterials, x-ray focusing, and x-ray sources. Also, we discuss concerns when dealing with x-rays such as radiation dosage. Through the use of quantities and assumptions backed by recent literature, manufacturer specifications, and personal correspondence, a full feasibility analysis of x-optogenetics is completed. The second proposed method we explore is u-optogenetics, which is the application of sonoluminescence to optogenetics. Such a technique uses ultrasound waves instead of x-rays to induce lig...

With this method I follow the empirical approach of other regionalists who have come to the conclusion that the opening-up of borders can lead to different dynamism. In this way I try to shed new light on the development possibilities and more increased economic interactions the Hungarian-Ukrainian borderland. The most important conclusion of this paper is the fact that with more intensive cross-border interactions not the neighbouring borderaland benefits but centrally located or larger towns in Hungary. In this way I can point to the fact that borderland dynamics could be quite limited in the research area. With this paper I could confirm previous studies and point to the fact that empirical analysis is needed to understand the local dynamism of a borderless space.

    There’s an embarrassment of choice for my message this week. Firstly, it was great to see a press release from the Japanese T2K (Tokai to Kamioka) experiment on 15 June, signalling not only potentially great physics, but also that the Japanese physics community is getting back on its feet after the earthquake and tsunami. Back home, the LHC is running beautifully...    Crossing the inverse femtobarn threshold so early into this years run is wonderful achievement, and augurs well for the summer conferences. We’ve now reached the stage where a single LHC fill is delivering as much data as the entire 2010 run. And finally, when Council met this week, I was pleased to announce that CERN has received formal confirmation from all five applicants for membership, opening the way to CERN welcoming new members soon. A busy two weeks, then, but what I’d like to focus on is the new result from Japan.   Simply stated, the T2K result shows the first indication of...

    1995-12-31

    The paper presents methods of evaluation of energy and economy related effects of different actions aimed at conservation in residential buildings. It identifies also the method of selecting the most effective way of distribution funds assigned to weatherization as well as necessary improvements to be implemented within the heating node and the internal heating system of the building. The analysis of data gathered for four 11-stories high residential buildings of {open_quotes}Zeran{close_quotes} type being subject of the Conservation Demonstrative Project, included a differentiated scope of weatherization efforts and various actions aimed at system upgrading. Basing upon the discussion of the split of heat losses in a building as well as the established energy savings for numerous options of upgrading works, the main problem has been defined. It consists in optimal distribution of financial means for the discussed measures if the total amount of funds assigned for modifications is defined. The method based upon the principle of relative increments has been suggested. The economical and energy specifications of the building and its components, required for this method have also been elaborated. The application of this method allowed to define the suggested optimal scope of actions within the entire fund assigned for the comprehensive weatherization.

  13. Possible new roles for tolerable risk mediators

    International Nuclear Information System (INIS)

    In his report on the Sizewell B Inquiry, the Inspector, Sir Frank Layfield, Q.C. introduced the term ''tolerable risk''. He regarded this as a better concept than the much abused and mis-interpreted phrase ''acceptable risk''. The application of tolerable risk implies that, even after regulation and incorporation of appropriate design safety criteria, there will always be a residual risk over which elements of the public will remain uneasy. They may tolerate, but they do not accept. They only tolerate because they have come to trust the process by which safety is assessed and delivered. This interpretation also implies that no safety target, the central theme of this meeting, should ever be regarded as stable or final. Such targets should continually be argued about and subject to regular searching review. Above all, such targets need to be re-justified to a doubting public so that they can be assured that the safety delivery process, namely the principles and management methods to ensure safety levels are actually met, is accountable and open for them to inspect. Thus the ''tolerable zone'' of nuclear plant safety is the product of procedures not simply assessments. These procedures need to be robust and adaptable. They need to be able to incorporate diversity of viewpoints and have a capacity to enable all who are involved to learn from each other's viewpoints and experience. In short the safety determination process needs to be more participatory and creative. (author)

  14. India has got the best possible agreement

    International Nuclear Information System (INIS)

    The Indians wanted an agreement that will be acceptable to their people and the IAEA wanted to make sure that Uncle Sam was on board. The positions of both are reflected in the balanced document that has been emerged from negotiations. The terms of the proposed inspections have been set without compromising India's sovereign right to manage its nuclear facilities in its best interests in the spirit of the India-US Joint Statement of 2005. The non-proliferationists complain that India got away with too much and the liberationists complain that India gave away too much in the negotiations on the safeguards agreement. The fact that India has nuclear weapons make the inspections less stringent. The expectations is that as India switches to indigenous fuel, the inspections will cease altogether. Much has been said about the reference to the 'corrective measures' that India may take in the event of disruption of supplies. The non- proliferationists and the liberationists find this provision too vague. One windfall that has come in India's way, whether by design or as logical consequence of the new approach, is that the other safeguards agreements, which are applicable to facilities that use imported fuel, will be suspended as long as the new safeguards agreement is in force. The goodwill of the IAEA and its Director General, Mohammed ElBaradei, has played a major role in the accomplish of this agreement.

  15. A Possibly Universal Red Chromophore for Jupiter

    2016-10-01

    A new laboratory-generated chemical compound made from photodissociated ammonia (NH3) molecules reacting with acetylene (C2H2) was suggested as a possible coloring agent for Jupiter's Great Red Spot (GRS) by Carlson et al. (2016, Icarus 274, 106-115). Baines et al. (2016, AAS/DPS Meeting abstract) showed that the GRS spectrum measured by the visual channels of the Cassini VIMS instrument in 2000 could be accurately fit by a cloud model in which the chromophore appeared as small particles in a physically thin layer immediately above the main cloud layer of the GRS. Here we show that the same chromophore and similar layer structure can also provide close matches to the 0.4-1 micron spectra of many other cloud features on Jupiter, suggesting that this material may be a nearly universal chromophore responsible for the various degrees of red coloration on Jupiter. This is a robust conclusion, even for 12 percent changes in VIMS calibration and large uncertainties in the refractive index of the main cloud layer due to uncertain fractions of NH4SH and NH3 in its cloud particles. The chromophore layer can account for color variations among north and south equatorial belts, equatorial zone, and the Great Red Spot, by varying particle size from 0.12 to 0.29 micron and optical depth from 0.06 to 0.76. The total mass of the chromophore layer is much less variable than its optical depth, staying mainly within 6-10 micrograms/cm2 range, but is only about half that amount in the equatorial zone. We also found a depression of the ammonia volume mixing ratio in the two belt regions, which averaged 0.4-0.5 × 10-4 immediately below the ammonia condensation level, while the other regions averaged twice that value.LAS and PMF acknowledge support from NASA Grant NNX14AH40G.

  16. Vitiligo: a possible model of degenerative diseases.

    Barbara Bellei

    Full Text Available Vitiligo is characterized by the progressive disappearance of pigment cells from skin and hair follicle. Several in vitro and in vivo studies show evidence of an altered redox status, suggesting that loss of cellular redox equilibrium might be the pathogenic mechanism in vitiligo. However, despite the numerous data supporting a pathogenic role of oxidative stress, there is still no consensus explanation underlying the oxidative stress-driven disappear of melanocytes from the epidermis. In this study, in vitro characterization of melanocytes cultures from non-lesional vitiligo skin revealed at the cellular level aberrant function of signal transduction pathways common with neurodegenerative diseases including modification of lipid metabolism, hyperactivation of mitogen-activated protein kinase (MAPK and cAMP response element-binding protein (CREB, constitutive p53-dependent stress signal transduction cascades, and enhanced sensibility to pro-apoptotic stimuli. Notably, these long-term effects of subcytotoxic oxidative stress are also biomarkers of pre-senescent cellular phenotype. Consistent with this, vitiligo cells showed a significant increase in p16 that did not correlate with the chronological age of the donor. Moreover, vitiligo melanocytes produced many biologically active proteins among the senescence-associated secretory phenotype (SAPS, such as interleukin-6 (IL-6, matrix metallo proteinase-3 (MMP3, cyclooxygenase-2 (Cox-2, insulin-like growth factor-binding protein-3 and 7 (IGFBP3, IGFBP7. Together, these data argue for a complicated pathophysiologic puzzle underlying melanocytes degeneration resembling, from the biological point of view, neurodegenerative diseases. Our results suggest new possible targets for intervention that in combination with current therapies could correct melanocytes intrinsic defects.

    Despite cerebral stroke being one of the main causes of acquired impairments of motor skills worldwide, well-established therapies to improve motor functions are sparse. Recently, attempts have been made to improve gross motor rehabilitation by mapping patient movements to sound, termed sonification. Sonification provides additional sensory input, supplementing impaired proprioception. However, to date no established sonification-supported rehabilitation protocol strategy exists. In order to examine and validate the effectiveness of sonification in stroke rehabilitation, we developed a computer program, termed "SonicPointer": Participants' computer mouse movements were sonified in real-time with complex tones. Tone characteristics were derived from an invisible parameter mapping, overlaid on the computer screen. The parameters were: tone pitch and tone brightness. One parameter varied along the x, the other along the y axis. The order of parameter assignment to axes was balanced in two blocks between subjects so that each participant performed under both conditions. Subjects were naive to the overlaid parameter mappings and its change between blocks. In each trial a target tone was presented and subjects were instructed to indicate its origin with respect to the overlaid parameter mappings on the screen as quickly and accurately as possible with a mouse click. Twenty-six elderly healthy participants were tested. Required time and two-dimensional accuracy were recorded. Trial duration times and learning curves were derived. We hypothesized that subjects performed in one of the two parameter-to-axis-mappings better, indicating the most natural sonification. Generally, subjects' localizing performance was better on the pitch axis as compared to the brightness axis. Furthermore, the learning curves were steepest when pitch was mapped onto the vertical and brightness onto the horizontal axis. This seems to be the optimal constellation for this two

    A science journalist in his 30th year covering human-driven climate change, including on three Arctic reporting trips, reflects on successes and setbacks as news media, environmentalists and Arctic communities have tried to convey the significance of polar change to a public for which the ends of the Earth will always largely be a place of the imagination.Novel challenges are arising in the 24/7 online media environment, as when a paper by a veteran climate scientist proposing a mechanism for abrupt sea-level rise became a big news story before it was accepted by the open-review journal to which it had been submitted. New science is digging in on possible connections between changing Arctic sea ice and snow conditions and disruptive winter weather in more temperate northern latitudes, offering a potential link between this distant region and the lives of ordinary citizens. As cutting-edge research, such work gets substantial media attention. But, as with all new areas of inquiry, uncertainty dominates - creating the potential for distracting the public and policymakers from the many aspects of anthropogenic climate change that are firmly established - but, in a way, boring because of that.With the challenges, there are unprecedented opportunities for conveying Arctic science. In some cases, researchers on expeditions are partnering with media, offering both scientists and news outlets fresh ways to convey the story of Arctic change in an era of resource constraints.Innovative uses of crittercams, webcams, and satellite observations offer educators and interested citizens a way to track and appreciate Arctic change. But more can be done to engage the public directly without the news media as an intermediary, particularly if polar scientists or their institutions test some of the established practices honed by more experienced communicators at NASA.

  20. Preliminary study of possible ORELA replacement options

    International Nuclear Information System (INIS)

    Based on two conceptual design studies performed by the LANL Accelerator Technology Division, the possibilities in terms of accelerator systems for replacing ORELA with a more intense Maxwellian-type continuous-energy neutron source are summarized and discussed. The neutron intensities from ORELA are compared with those from existing or potential accelerator systems used for cross-section and condensed-matter studies. The best replacement options seem to involve a spallation source from 200- to 400-MeV protons on an ORELA-like target. Pulsing and intensity desiderata with such a source are discussed which correspond to a spectrum-averaged 100-fold improved figure of merit over ORELA for TOF measurements with only a tenfold increased source strength. Existing accelerator designs seem to be inadequate for such a source. Consequently, two conceptual designs were developed for this study by the LANL Accelerator Technology Division. The first conceptual design is for a 200-MeV large linac capable of accelerating 1.3 A during a macropulse; this linac standing alone could serve as an ORELA replacement source. The second conceptual design is for a much smaller 250-MeV PIGMI linac with a 28-mA macropulse current which feeds a proton accumulator ring and bunch-compressor transport line. This linac-ring-compressor (LIRIC) option would give a more cost-effective neutron source for cross-section measurements, whereas the large linac, or a modified version of it, would give a much simpler system more suitable for expansion. In particular, both conceptual designs would incorporate the present ORELA building and would provide approximately 100-fold improved neutron sources over ORELA for cross-section measurements. The total estimated cost of the LIRIC system would be $43M (1984), whereas the cost of the large linac would be about a factor of two more. 55 references, 11 figures, 19 tables

  1. Natural gas in Norway - Possibilities and limitations

    International Nuclear Information System (INIS)

    Norway is rich in gas resources. In recent years, gas sales from the Norwegian continental shelf have been in the order of 25 to 30 billion Sm3/yr and are expected to increase strongly the next 10 to 15 years. However, a scattered population, a difficult topography, long distances between large potential consumers and where the gas is brought ashore, make it difficult to utilize the gas commercially in this country. Moreover, the gas will have to compete with a highly developed hydro-electric network. This report evaluates possibilities and hindrances in the establishment of a home market for natural gas in Norway. The low population density implies that using gas for preheating of water, heating of rooms etc will not become important except, perhaps, locally, where gas may be available for other reasons. As a source of energy and raw material in many industrial processes, natural gas can become important in some coastal areas and in central parts of eastern Norway. Discussions are in progress on gas power stations for electricity production. This has aroused some controversy because of environmental problems, and for political acceptance gas power will have to replace coal power. As a fuel, gas may be of interest for domestic ferries and for busses. A lack of capital under financial risk and gas prices limit the market development. Although tax policy is presently favourable to gas power, the risk taken by private investors in converting to natural gas is increased by their not knowing for how long the gas will be exempt from environmental tax. 74 refs., 8 figs., 27 tabs

    The interaction of intense laser light with relativistic electrons can produce unique sources of high-energy x rays and gamma rays via Thomson scattering. ''Thomson-Radiated Extreme X-ray'' (T-REX) sources with peak photon brightness (photons per unit time per unit bandwidth per unit solid angle per unit area) that exceed that available from world's largest synchrotrons by more than 15 orders of magnitude are possible from optimally designed systems. Such sources offer the potential for development of ''nuclear photo-science'' applications in which the primary photon-atom interaction is with the nucleons and not the valence electrons. Applications include isotope-specific detection and imaging of materials, inverse density radiography, transmutation of nuclear waste and fundamental studies of nuclear structure. Because Thomson scattering cross sections are small, < 1 barn, the output from a T-REX source is optimized when the laser spot size and the electron spot size are minimized and when the electron and laser pulse durations are similar and short compared to the transit time through the focal region. The principle limitation to increased x-ray or gamma-ray brightness is ability to focus the electron beam. The effects of space charge on electron beam focus decrease approximately linearly with electron beam energy. For this reason, T-REX brightness increases rapidly as a function of the electron beam energy. As illustrated in Figure 1, above 100 keV these sources are unique in their ability to produce bright, narrow-beam, tunable, narrow-band gamma rays. New, intense, short-pulse, laser technologies for advanced T-REX sources are currently being developed at LLNL. The construction of a {approx}1 MeV-class machine with this technology is underway and will be used to excite nuclear resonance fluorescence in variety of materials. Nuclear resonance fluorescent spectra are unique signatures of each isotope and provide an

  3. RESSOURCES ALLOCATION POSSIBILITIES WITHIN HEALTH SERVICES

    Full Text Available The state policy in the health care area must take into account the complexity and specificity of the domain. Health means not only “to treat”, but also “to prevent” and “to recover and rehabilitate the individual physically”. Regardless of the adopted health insurance system, the health system is facing a big problem and this is the insufficient funds necessary to function properly. The underfunding may have various causes, from a wrong health policy, based on “treating” instead of “preventing”, by the misuse of funds. This papers intended to formulate assumptions that underpin the research I am conducting within the Doctoral Research Program held at the Valahia University of Targoviste, which aims at using the management control in increasing the health services performance. The application of the accounting and management control methods in determining health costs can be a beginning to streamline the system. This is also a result of the fact that health care is a public service with specific characteristics: it can not be subject only to market requirements but at the same time he must undergo an administrative savings, representing a typical case of market failure. The increased cost of treatment, as well as the decline in their quality can be determined by the discrepancy between the funding and payment mechanisms. Different payment systems currently available do nothing but perpetuate the shortcomings in the system. Switching to the introduction of cost and budgets by cost centers or object (if solved can be a step forward for a better management of resources. In this context, we consider as a necessity to be imposed the cost analysis on responsibility centers, the definition of the cost object and cost center identification and determination of direct costs and those indirect services to choose the basis for the allocation of cost centers and the determination of each actual cost per diagnosis.

  4. A possible molecular metric for biological evolvability

    Indian Academy of Sciences (India)

    Aditya Mittal; B Jayaram

    2012-07-01

    Proteins manifest themselves as phenotypic traits, retained or lost in living systems via evolutionary pressures. Simply put, survival is essentially the ability of a living system to synthesize a functional protein that allows for a response to environmental perturbations (adaptation). Loss of functional proteins leads to extinction. Currently there are no universally applicable quantitative metrics at the molecular level for either measuring ‘evolvability’ of life or for assessing the conditions under which a living system would go extinct and why. In this work, we show emergence of the first such metric by utilizing the recently discovered stoichiometric margin of life for all known naturally occurring (and functional) proteins. The constraint of having well-defined stoichiometries of the 20 amino acids in naturally occurring protein sequences requires utilization of the full scope of degeneracy in the genetic code, i.e. usage of all codons coding for an amino acid, by only 11 of the 20 amino acids. This shows that the non-availability of individual codons for these 11 amino acids would disturb the fine stoichiometric balance resulting in non-functional proteins and hence extinction. Remarkably, these amino acids are found in close proximity of any given amino acid in the backbones of thousands of known crystal structures of folded proteins. On the other hand, stoichiometry of the remaining 9 amino acids, found to be farther/distal from any given amino acid in backbones of folded proteins, is maintained independent of the number of codons available to synthesize them, thereby providing some robustness and hence survivability.

  5. Possibilities of psychoacoustics to determine sound quality

    Genuit, Klaus

    For some years, acoustic engineers have increasingly become aware of the importance of analyzing and minimizing noise problems not only with regard to the A-weighted sound pressure level, but to design sound quality. It is relatively easy to determine the A-weighted SPL according to international standards. However, the objective evaluation to describe subjectively perceived sound quality - taking into account psychoacoustic parameters such as loudness, roughness, fluctuation strength, sharpness and so forth - is more difficult. On the one hand, the psychoacoustic measurement procedures which are known so far have yet not been standardized. On the other hand, they have only been tested in laboratories by means of listening tests in the free-field and one sound source and simple signals. Therefore, the results achieved cannot be transferred to complex sound situations with several spatially distributed sound sources without difficulty. Due to the directional hearing and selectivity of human hearing, individual sound events can be selected among many. Already in the late seventies a new binaural Artificial Head Measurement System was developed which met the requirements of the automobile industry in terms of measurement technology. The first industrial application of the Artificial Head Measurement System was in 1981. Since that time the system was further developed, particularly by the cooperation between HEAD acoustics and Mercedes-Benz. In addition to a calibratable Artificial Head Measurement System which is compatible with standard measurement technologies and has transfer characteristics comparable to human hearing, a Binaural Analysis System is now also available. This system permits the analysis of binaural signals regarding physical and psychoacoustic procedures. Moreover, the signals to be analyzed can be simultaneously monitored through headphones and manipulated in the time and frequency domain so that those signal components being responsible for noise

Given that the method allows rapid collection ( <30 minutes per site) of this information we anticipate that this method will be widely applicable. Validation of this photopoint method against field measures and terrestrial lidar that was acquired coincidently is progressing and we look forward to further tests to quantify the accuracy of these methods and to account of the effect of occlusion. We are working on automating the extraction of this information and delivering these products freely online. We also hope to investigate the feasibility of the automatic extraction of growth form of species in the photographs to assist with site structural assessment.

  11. Possible Progenitor of Special Supernova Type Detected

    2008-04-01

    Using data from NASA's Chandra X-ray Observatory, scientists have reported the possible detection of a binary star system that was later destroyed in a supernova explosion. The new method they used provides great future promise for finding the detailed origin of these important cosmic events. In an article appearing in the February 14th issue of the journal Nature, Rasmus Voss of the Max Planck Institute for Extraterrestrial Physics in Germany and Gijs Nelemans of Radboud University in the Netherlands searched Chandra images for evidence of a much sought after, but as yet unobserved binary system - one that was about to go supernova. Near the position of a recently detected supernova, they discovered an object in Chandra images taken more than four years before the explosion. Optical image of SN 2007on Optical image of SN 2007on The supernova, known as SN 2007on, was identified as a Type Ia supernova. Astronomers generally agree that Type Ia supernovas are produced by the explosion of a white dwarf star in a binary star system. However, the exact configuration and trigger for the explosion is unclear. Is the explosion caused by a collision between two white dwarfs, or because a white dwarf became unstable by pulling too much material off a companion star? Answering such questions is a high priority because Type Ia supernovas are major sources of iron in the Universe. Also, because of their nearly uniform intrinsic brightness, Type Ia supernova are used as important tools by scientists to study the nature of dark energy and other cosmological issues.

    Bit commitment protocols whose security is based on the laws of quantum mechanics alone are generally held to be impossible. In this paper we give a strengthened and explicit proof of this result. We extend its scope to a much larger variety of protocols, which may have an arbitrary number of rounds, in which both classical and quantum information is exchanged, and which may include aborts and resets. Moreover, we do not consider the receiver to be bound to a fixed "honest" strategy, so that "anonymous state protocols", which were recently suggested as a possible way to beat the known no-go results are also covered. We show that any concealing protocol allows the sender to find a cheating strategy, which is universal in the sense that it works against any strategy of the receiver. Moreover, if the concealing property holds only approximately, the cheat goes undetected with a high probability, which we explicitly estimate. The proof uses an explicit formalization of general two party protocols, which is applic...

  17. After Chernobyl. Possibilities of phasing out nuclear power in Sweden

    International Nuclear Information System (INIS)

    According to the currently applicable Parliamentary decision, the phasing out of nuclear power in Sweden must be completed by the year 2010. The National Energy Administration has analyzed the following questions. If it were to become evident that operating several or all of the Swedish nuclear power plants entailed serious risks, what possibilities would there be of phasing them out in the short term or over a longer period. And what would the consequences be with regard to the national economy and the environment? First we report the consequences of a rapid phase-out. Here, it is assumed that several or all nuclear plants would be taken out of operation within a period of two years. Available compensatory resources would be limited to more intensive utilization of existing hydropower, back-pressure plants, combined power and heating plants and oil-fired plants. The second alternative is a phase-out in ten years. Moreover, a case is discussed in which phase-out is planned and implemented from 1987 to 2005. Such a plan would provide industry more time to adjust, while a number of alternative techniques and fuels could be used to replace nuclear power. The consequences of the different phase-out alternatives can be described only within a framework of certain assumptions regarding the worldwide development. Important factors here include fuel prices and economic trends. Environmental restrictions comprise another important prerequisite

    Full Text Available Premature ovarian failure (POF is characterized by impairment of ovarian function unrelated to elevatedfollicle-stimulating hormone (FSH before the age of 40. The consequence of POF is severe and distinctive, presentingfrom infertility to symptoms caused by hormone deprivation. The mechanism of POF remains unclearand current treatments are therefore ineffective. Melatonin (N-acetyl-5-methoxytryptamine is a neuroendocrinalhormone chiefly secreted by the pineal body. Melatonin exerts extensive physiological and pharmacologicaleffects on the biological rhythm, oxidative stress, reproduction, autoimmune and tumourigenesis. However,current researches have not yet brought melatonin into the study of POF. In the present review, we have involvedstate-of-the-art research progress of melatonin in ovary with regard to oxidation, follicle formation and function,and ovarian autoimmune disorders since these aspects mainly dispose to POF development. The features thatmelatonin scavenges reactive oxygen species (ROS, directly and indirectly induces follicle maturation, ovulationand inhibits apoptosis, and modulates autoimmune derangements in the ovaries are highly indicative that melatonincan effect in combating POF. Also, in this respect we have discussed the possibility of applying melatoninin the treatment of POF and have listed evidence of studies in vitro and in vivo. Vacant research directions aresubsequently suggested and the future application of melatonin in POF treatment is prospected.

    The laser-induced plasma-assisted ablation (LIPAA) process developed by our group, in which a single conventional pulsed laser is only used, makes it possible to perform high-quality and high-speed glass microfabrication. Up to the present, this process has been widely applied for micromachining of various transparent hard and soft materials. In this process, a laser beam is first directed to a glass substrate placed in vacuum or air. The laser beam passes through the substrate since the wavelength of the laser beam must have no absorption by the substrate for the LIPAA process. The transmitted laser beam is absorbed by a solid target (typically a metal), located behind the substrate. The target is then ablated, resulting in plasma generation. Due to the interaction of the laser beam and the laser-induced plasma, significant ablation takes place at the rear surface of the substrate. Recently, we have developed the proto-type LIPAA system using a second harmonic of diode pumped Q-switched Nd:YAG laser for the practical use. In this paper, we will demonstrate micromachining, crack-free marking, color marking and dicing of glass materials. Additionally, selective metallization of glass and polyimide by the LIPAA process followed by metal chemical-plating is investigated. The discussion includes mechanism and practical applications in micro-electronics industry of the LIPAA process.

  20. Is non-directive communication in genetic counseling possible?

    Pennacchini, M; Pensieri, C

    2011-01-01

    In 2007, over 560,000 genetic tests were performed in Italy. However, only 70,154 genetic counseling sessions were conducted. Some say that non-directive counseling is necessary so that the patient understands the test results and the different options available and that the physician should not influence the patient's free choice. We need to clarify the meaning of non-directive consultation and if it is in fact possible. Each doctor has his own values and, in order to achieve the intended purpose, he will give information that, with his verbal, para-verbal and body language will guide the patient to one decision or another. Taking into account the axiom of effective communication "You can't NOT communicate", non-directive counseling is very difficult or even impossible. In genetic counseling, the knowledge that the patient receives of the correct diagnosis and related medical facts and of the applicable genetic considerations is basic to the entire process. Nonetheless, such knowledge in itself is not sufficient if it cannot be appropriately imparted to the interested person or persons. We think "persuasion" is not the right method, but instead "convince" meaning "co-win", "win together" may be the best approach to a problem of such great importance. The counselor will have achieved the desired goal with his patient if he is able to channel the emotion towards a mutually beneficial objective. The primary goal is not to persuade but to win-together (convince) with the patient and the unborn child.
