    Preparative synthesis of compounds with the aid of radiation chemistry is increasingly used in laboratories as well as on a technical scale. A large number of new compounds has been produced with the methods of radiation chemistry. With the increasing number of available radiation sources, also the number of synthesis metods in radiation chemistry has increased. This paper can only briefly mention the many possible ways of synthesis in radiation chemistry. (orig./HK) [de

  2. Research in radiation chemistry

    Silverman, J.

    1974-01-01

    In the survey the author discusses phenomena which are unique to radiation chemistry, as well as those in which radiation chemistry research plays a principal role. Works in this field such as spur phenomena and effects of scavengers in the radiolysis of water and liquid alkane, intraspur effects in styrene and polymerization of styrene at high dose rates are presented. The problem of the missing hydrogen atoms in irradiated alkanes needs answer and sensitization of crosslinking reactions may involve some unique aspects of radiation chemistry. Pairwise trapping of radicals in irradiated n-hydrocarbons have been observed in ESP-spectra. A well defined spectrum of radical pairs when the crystals of n-eicosane is irradiated and observed at 77 deg K. The nature of the spectrum, its changes with temperature and the effect of LET is discussed in the paper. (M.S.)

  3. Bibliographies on radiation chemistry

    Hoffman, M.Z.; Ross, A.B.

    1986-01-01

    The one-electron oxidation and reduction of metal ions and complexes can yield species in unusual oxidation states, and ligand-radicals coordinated to the central metal. These often unstable species can be mechanistically important intermediates in thermal, photochemical, and electrochemical reactions involving metal-containing substances. Their generation via radiolysis provides an alternate means of characterizing them using kinetic and spectroscopic techniques. We hope these bibliographies on the radiation chemistry of metal ions and complexes, presented according to periodic groups, will prove useful to researchers in metallo-redox chemistry. These bibliographies contain only primary literature sources; reviews are not included. However, a list of general review articles on the radiation chemistry of metal ions and complexes is presented here in the first section which covers cobalt, rhodium and iridium, Group 9 in the new IUPAC notation. Additional parts of the bibliography are planned, covering other periodic groups. Part A of the bibliography was prepared by a search of the Radiation Chemistry Data Center Bibliographic Data Base (RCDCbib) through January 1986 for papers on rhodium, iridium and cobalt compounds, and radiolysis (both continuous and pulsed). Papers in which the use of metal compounds was incidental to the primary objective of the study were excluded. Excluded also were publications in unrefereed and obscure sources such as meeting proceedings, internal reports, dissertations, and patents. The majority of the studies in the resultant compilation deal with experiments performed on solutions, mainly aqueous, although a substantial fraction is devoted to solid-state esr measurements. The references are listed in separate sections for each of the metals, and are presented in approximate chronological order. (author)

  4. Bibliographies on radiation chemistry

    International Nuclear Information System (INIS)

    This bibliography lists about 400 papers dealing solely with the production and reactivity of superoxide radical anions in irradiated aqueous and organic liquids. Only papers dealing with quantitative mechanistic, spectroscopic or kinetic data have been included. The listing was prepared by searching the RCDC bibliographic data base with SELECT keywords O 2 - or HO 2 and aqueous solution. The key words radicals (oxygen), peroxy radicals, pulse radiolysis, flash radiolysis, esr and gamma rays were also used. Additional relevant references were obtained from inspection of reviews, individual author indexes and cited references. The present bibliography excludes solid and gas phase studies, and also technical, government and in-house reports, theses, patents and some symposia proceedings. Several references prior to 1960 have been added, and the list should be reasonably comprehensive from 1965-1980. The listing is in chronological order, according to year of publication in the categories Photochemistry, Radiation Chemistry, Other, and Reviews. (author)

    Future perspectives of radiation chemistry are discussed by the analysis of the related information in detail as obtained from our recent surveys of publications and scientific meetings in radiation chemistry and its neighboring research fields, giving some examples, and are summarized as follows. (1) Traditionally important core-parts of radiation chemistry should be activated more. The corresponding research programs are listed in detail. (2) Research fields of physics, chemistry, biology, medicine, and technology in radiation research should interact more among them with each other. (3) Basic research of radiation chemistry should interact more with its applied research. (4) Interface research fields with radiation chemistry should be produced more with mutually common viewpoints and research interests between the two. Interfaces are not only applied research but also basic one.

  6. Bibliographies on radiation chemistry

    International Nuclear Information System (INIS)

    This bibliography lists about 280 papers dealing with the formation, properties and reactions of free radicals containing the 1,2- or 1,4-benzosemiquinone moiety. Related species such as those prepared from camphorquinone, quinone methides and aromatic compounds like flavins and certain dyestuffs are excluded. The bibliography is almost completely confined to studies of semiquinones produced in irradiated systems. Chemical, biological and electrochemical generation of the intermediates are not covered. Papers on reduction of quinones or oxidation of hydroquinones containing no quantitative information on the semiquinone intermediates are likewise not included. The bibliography was prepared by a search of the Radiation Chemistry Data Center bibliographic data base using the keywords semiquinones, quinones, hydroquinones, pulse radiolysis and flash photolysis. The keywords gamma rays (radiolysis), photolysis and quinones also yielded some pertinent references, and inspection of several reviews and the cited references in a few papers revealed additional references. While earlier references known to the authors have been included, the bibliography mainly contains references since 1970 and coverage extends through August, 1980. (author)

    Full text: The theme of the 2000 Gordon Conference on Radiation Chemistry was 'diversity'. The range of topics covered was heralded by the opening presentations which went from the galactic to molecular biology, radiation chemistry and non thermal surface processes in the outer solar system to achievements and open challenges in DNA research. The rest of the conference reflected the extended usage of radiation chemistry -its processes and techniques - applied to a panorama of topics. The ability to generate either oxidising or reducing free radicals in known quantities has been the foundation stone on which all applications are based. In particular it is noticeable that biological systems have been attempted by an increasing number of workers, such as studies of biological ageing and also reactions of nitric oxide in biological environments. Electron transfer processes in proteins are straightforward applications of solvated electron chemistry even if the results are not straightforward in their interpretation. Other topics presented include, radiation chemical processes induced in: supercritical CO 2 , treatment of contaminated materials, 3-dimensional Fullerenes, zeolites and radiation catalysis. In material science, aspects of ions and excited states in polymers, conducting polymers, donor acceptor processes in photo curing, enhancement of photo-electron yields in doped silver halides- improvement of the photographic process, radiation chemistry in cages and bubbles are discussed. The fundamental aspects of radiation chemistry are not yet all worked out. Subpicosecond pulsed electron beam sources, some of them 'tabletop', are still being planned to probe the early events in radiation chemistry both in water and in organic solvents. There is still an interest in the chemistry produced by pre-solvated electrons and the processes induced by heavy ion radiolysis.

    The rather strong and many-sided pollution of the environment (atmosphere, water resources, soil) as a consequence of human activities is summarized. The solution of the arised problems by application of radiation chemistry methods and the utilization of modern environmentally ''clean'' and economical technologies, founded on electron beam processing, are mentioned. Some basic environmental problems and their solution are briefly discussed: i) Removal of CO 2 from flue gases and its radiation induced utilization. ii) Principals for degradation of aqueous pollutants by electron beam processing in the presence of ozone (synergistic effect). The radiation chemistry as a modern and manifold discipline with very broad applications can also essentially contribute in the conservation of the environment

    1968-01-01

    In recent years considerable progress has been made in understanding the fundamental chemical reactions that occur when materials are irradiated. This has followed from the development of new techniques for studying these reactions. The International Atomic Energy Agency held a Panel on Radiation Chemistry in Vienna on 17-21 April 1967, to review the current status of various sources, new techniques in radiation chemistry, and their applications. The main sources mentioned by the Panel were isotope sources, electron accelerators, and chemonuclear reactors. Among the basic techniques discussed were pulsed radiolysis, flash photolysis, fast ESR methods, irradiation at liquid helium temperatures, electric discharge methods and far ultra-violet methods. Interesting industrial applications were discussed, such as the development of wood-plastic combinations, and a paper was given on the curing of paints and thin films Refs, figs and tabs

    1980-01-01

    The physical aspects of the energy deposit of fast particles in matter initiate chemical effects which are merged with the early physical processes. Here only radiation chemistry and its relationship to the initial energy deposit are of concern. The primary objective of our track studies is, however, application to biology. In the radiolytic decomposition of water energy is absorbed almost exclusively in water, and the principal chemistry is that of radiation decomposition of water. The track structure in water is expected to be virtually the same as that in a biological system. The study of radiation chemistry of dilute solutions, therefore, provides another method to investigate the structure of tracks as they are likely to be present in an irradiated biological system but at times much longer than they are accessible to purely physical measurements

    Radiation chemistry began as early radiotherapists needed a reliable and appropriate dosimeter. The iron sulphate dosimeter, using ferrous iron in sulphuric acid and oxidation by irradiation, was a nasty brew of chemicals but it was sensitive, reliable and conveniently had the same density as human tissue. Water irradiation chemistry studies were driven by the need to understand the fundamental processes in radiotherapy; to control the corrosion problems in the cooling/ heat exchange systems of nuclear reactors and to find stable solvents and reagents for use in spent fuel element processing. The electrical and mechanical stability of materials in high radiation fields stimulated the attention of radiation chemists to the study of defects in solids. The coupled use of radiation and Electron Spin Resonance (ESR) enabled the identity of defect structures to be probed. This research led to the development of the sensitive Thermoluminescent Dosimeters, TLD's and a technique for dating of archaeological pottery artefacts. Radiation chemistry in the area of medicine is very active with fundamental studies of the mechanism of DNA strand breakage and the development of radiation sensitisers and protectors for therapeutic purposes. The major area of polymer radiation chemistry is one which Australia commands great international respect

    Water radiolysis in presence of N 2 is probably the topic the most controversy in the field of water radiolysis. It still exists a strong discrepancy between the different reports of ammonia formation by water radiolysis in presence of N 2 and moreover in absence of oxygen there is no agreement on the formation or not of nitrogen oxide like NO 2 - and NO 3 -. These discrepancies come from multiple sources: - the complexity of the reaction mechanisms where nitrogen is involved - the experimental difficulties - and, the irradiation conditions. The aim of the workshop is to capitalize the knowledge needed to go further in simulations and understanding the problems caused (or not) by the presence of nitrogen / water in the environment of radioactive materials. Implications are evident in terms of corrosion, understanding of biological systems and atmospheric chemistry under radiation. Topics covered include experimental and theoretical approaches, application and fundamental researches: - Nitrate and Ammonia in radiation chemistry in nuclear cycle; - NOx in biological systems and atmospheric chemistry; - Formation of Nitrogen compounds in Nuclear installations; - Nitrogen in future power plant projects (Gen4, ITER...) and large particle accelerators. This document gathers the transparencies available for 7 of the presentations given at this workshop. These are: - H.E SIMS: 'Radiation Chemistry of Nitrogen Compounds in Nuclear Power Plant'; - G.R.

    2009-01-01

    This article seeks to illustrate some contributions of radiation chemistry to radiobiology and related science, and to draw attention to examples where radiation chemistry is central to our knowledge of specific aspects. Radiation chemistry is a mature branch of radiation science which is continually evolving and finding wider applications. This is particularly apparent in the study of the roles of free radicals in biology generally, and radiation biology specifically. The chemical viewpoint helps unite the spatial and temporal insight coming from radiation physics with the diversity of biological responses. While historically, the main application of radiation chemistry of relevance to radiation biology has been investigations of the free-radical processes leading to radiation-induced DNA damage and its chemical characterization, two features of radiation chemistry point to its wider importance. First, its emphasis on quantification and characterization at the molecular level helps provide links between DNA damage, biochemical repair processes, and mutagenicity and radiosensitivity. Second, its central pillar of chemical kinetics aids understanding of the roles of 'reactive oxygen species' in cell signalling and diverse biological effects more generally, and application of radiation chemistry in the development of drugs to enhance radiotherapy and as hypoxia-specific cytotoxins or diagnostic agents. The illustrations of the broader applications of radiation chemistry in this article focus on their relevance to radiation biology and demonstrate the importance of synergy in the radiation sciences. The past contributions of radiation chemistry to radiation biology are evident, but there remains considerable potential to help advance future biological understanding using the knowledge and techniques of radiation chemistry.

  17. The radiation chemistry of colloids

    International Nuclear Information System (INIS)

    Sellers, R.M.

    1976-08-01

    One of the most important problems associated with water cooled reactors is the accumulation on the pipework of radio-active deposits. These are formed from corrosion products which become activated during their passage through the reactor core. The first step of the activation process involves the deposition of the corrosion products, which are present as either colloidal or particulate matter, onto surfaces in the reactor core, i.e. within the radiation zone. A review of the literature on the effect of radiation on colloids is presented. Particular emphasis is given to the dependence of colloidal parameters such as particle size, turbidity and electrophoretic mobility on radiation dose. Most of the data available is of a qualitative nature only. Evidence is presented that colloids of iron are affected (in some cases precipitated) by radiation, and it is suggested that this process plays a part in the deposition of corrosion products in nuclear reactor cores. The bulk of the information available can be rationalized in terms of the radiation chemistry of aqueous solutions, and the interaction of the radicals produced with the atoms or molecules at the surface of the colloidal particles. This approach is very successful in explaining the variation of the mean particle size of monodisperse sulphur hydrosols with dose, for which quantitative experimental data are available. (author)

    1976-01-01

    During the past 25 years there has been a steady recognition that radiation in the form of electrons or gamma rays can offer positive advantages as a processing technology. Underlying this process industry, and largely responsible for its success, are significant contributions from the field of basic and applied radiation chemistry. In this paper it is attempted to relate fundamental radiation chemistry studies directly to the practical engineering applications

  1. Advanced radiation chemistry research: Current status

    International Nuclear Information System (INIS)

    1995-10-01

    Radiation chemistry is a branch of chemistry that studies chemical transformations in materials exposed to high-energy radiations. It is based on the use of ionizing radiation as the initiator or catalyst in chemical reactions. The most significant advantage of radiation chemistry lies in its ability to be used in the production and study of almost any reactive atomic and molecular species playing a part in chemical reaction, synthesis, industrial processes, or in biological systems. Over the the last few years a number of meetings have taken place, under the auspices of the IAEA, in order to evaluate recent developments in radiation chemistry as well as the trends indicated by the results obtained. Radiation chemists from different countries have participated at these meetings. The present publication, a companion to the previous publication - New Trends and Development in Radiation Chemistry, IAEA-TECDOC-527 (1989) - includes some of the important contributions presented at these meetings. It is hoped that it will provide a useful overview of current activities and of emerging trends in this field, thus promoting better understanding of potential contributions of radiation chemistry to other fields of knowledge as well as to practical applications in industry, medicine and agriculture.

  2. Radiation chemistry: basic, strategic or tactical science?

    International Nuclear Information System (INIS)

    Wardman, Peter

    1989-01-01

    The work of Weiss in the 1930s, particularly with Haber, has only recently been recognized to have implications in biology and medicine. Similarly, research in radiation chemistry and the application of the pulse radiolysis technique, for example, have implications far beyond traditional radiation chemistry. Some examples of such research are discussed against a background of categorization into 'basic', 'strategic' or 'tactical' science. Examples discussed include redox properties of free radicals, and the identification and characterization of nitro radicals as intermediates in drug metabolism. Radical reactions often take place in multicomponent systems, and the techniques of radiation chemistry can be used to probe, for example, events occurring at interfaces in micelles. Industrial processes involving radiation are attracting investment, particularly in Japan. (author)

    Buxton, G.V.

    1987-01-01

    More is known about the radiation chemistry of water than any other liquid. From a practical viewpoint out knowledge is virtually complete, and water radiolysis now provides a very convenient way of generating an enormous variety of unstable species under well-defined conditions. This facility, coupled with the techniques of pulse radiolysis, has opened up new areas in aqueous inorganic, organic, and biochemistry that cannot be readily studied by thermal or photochemical methods. This chapter is aimed, therefore, at those who wish to use radiolytic methods to generate and study unstable species in aqueous solution. The basic features of the radiation chemistry of water are described first to show how the primary radical and molecular products evolve with time and to delineate the bounds of useful experimental conditions. Next, the properties of the primary radicals are summarized, and examples are given to show how the primary radicals can be converted into secondary radicals, often of a single kind. This is an important aspect of the radiation chemistry of aqueous solutions. Lastly, the impact of our knowledge of the radiation chemistry of water on advances in general chemistry is illustrated by examples from the fields of inorganic and organic chemistry

  9. 2010 Gordon Research Conference On Radiation Chemistry

    International Nuclear Information System (INIS)

    Orlando, Thomas

    2010-01-01

    The 2010 Gordon Conference on Radiation Chemistry will present cutting edge research regarding the study of radiation-induced chemical transformations. Radiation Chemistry or 'high energy' chemistry is primarily initiated by ionizing radiation: i.e. photons or particles with energy sufficient to create conduction band electrons and 'holes', excitons, ionic and neutral free radicals, highly excited states, and solvated electrons. These transients often interact or 'react' to form products vastly different than those produced under thermal equilibrium conditions. The non-equilibrium, non-thermal conditions driving radiation chemistry exist in plasmas, star-forming regions, the outer solar system, nuclear reactors, nuclear waste repositories, radiation-based medical/clinical treatment centers and in radiation/materials processing facilities. The 2010 conference has a strong interdisciplinary flavor with focus areas spanning (1) the fundamental physics and chemistry involved in ultrafast (atto/femtosecond) energy deposition events, (2) radiation-induced processes in biology (particularly spatially resolved studies), (3) radiation-induced modification of materials at the nanoscale and cosmic ray/x-ray mediated processes in planetary science/astrochemistry. While the conference concentrates on fundamental science, topical applied areas covered will also include nuclear power, materials/polymer processing, and clinical/radiation treatment in medicine. The Conference will bring together investigators at the forefront of their field, and will provide opportunities for junior scientists and graduate students to present work in poster format or as contributors to the Young Investigator session. The program and format provides excellent avenues to promote cross-disciplinary collaborations.

    Among all the environmental hazards to which man is exposed, ionizing radiation is the most thoroughly investigated and the most responsibly monitored and controlled. Nevertheless, because of the importance of radiation in modern society from both the hazard as well as the utilitarian standpoints, much more information concerning the biological effects induced and their modification and reversal is required. Together with radiation physics, an understanding of radiation chemistry is necessary for full appreciation of biological effects of high and low energy radiations, and for the development of prophylactic, therapeutic and potentiating methods and techniques in biological organisms

  11. Radiation Chemistry and Photochemistry of Ionic Liquids

    International Nuclear Information System (INIS)

    Wishart, J.F.; Takahaski, K.

    2010-01-01

    As our understanding of ionic liquids and their tunable properties has grown, it is possible to see many opportunities for ionic liquids to contribute to the sustainable use of energy. The potential safety and environmental benefits of ionic liquids, as compared to conventional solvents, have attracted interest in their use as processing media for the nuclear fuel cycle. Therefore, an understanding of the interactions of ionizing radiation and photons with ionic liquids is strongly needed. However, the radiation chemistry of ionic liquids is still a relatively unexplored topic although there has been a significant increase in the number of researchers in the field recently. This article provides a brief introduction to ionic liquids and their interesting properties, and recent advances in the radiation chemistry and photochemistry of ionic liquids. In this article, we will mainly focus on excess electron dynamics and radical reaction dynamics. Because solvation dynamics processes in ionic liquids are much slower than in molecular solvents, one of the distinguishing characteristics is that pre-solvated electrons play an important role in ionic liquid radiolysis. It will be also shown that the reaction dynamics of radical ions is significantly different from that observed in molecular solvents because of the Coulombic screening effects and electrostatic interactions in ionic liquids.

  12. General survey of radiation chemistry in France

    International Nuclear Information System (INIS)

    Gilles, L.

    1989-01-01

    A recent symposium held in France allowed the meeting of about a hundred French speaking scientists, fundamental and applied researchers as well as industrialists, interested in the field of radiation chemistry. Five principal topics will be considered: 1. Studies on the primary effects of the interaction of radiation with matter for which a strong correlation appears between radiolytic and photolytic studies to understand the solvation process of electrons; 2. Studies of chemical reactions induced by radiolysis for which the use of heavy ions can give a new impulse; 3. Studies on the effects of radicals in biochemistry for which the radiolytic methods appear the best way to produce radicals involved in biological mechanism as, for instance, respiration; 4. Studies on the biological effects of radiation and more particularly some effects of hydroxyl radical; 5. Some industrial applications of radiation for grafting and reticulation of polymers with a view to destroying pathogenic germs in food. The fate of water and solutes used in nuclear reactors as well as the effects of irradiation on nuclear wastes will also be considered. New questions in radiation chemistry will suggest studies in which radiolytic methods are essential. 1 tab

    This document was prepared to meet FCR&D level 3 milestone M3FT-16IN030104052, “continue the study of the short chain compounds,” and, “ study the radiolysis of the non-symmetrical DGA (D3DODGA)….,” under the Radiation Chemistry FCR&D work package. Toward these goals, the short chain DGA, tetraethyldiglycolamide (TEDGA) was investigated for its hydrolytic stability in HNO3 solution, with comparisons to the less oxidizing mineral acid HCl. Initial gamma-irradiations were also performed on DGA solutions, to inform a more detailed investigation of several short chain compounds anticipated for FY17. The hydrolytic and radiolysis behavior of TEDGA is of interest for two reasons. First, previous long chain DGA radiolysis was conducted in dodecane solution since the long chain compounds are soluble in that diluent, and new radiation chemistry is expected in the aqueous environment due to reactions with •OH radical. The second reason is that this water-soluble DGA has been proposed for use as a stripping or holdback agent in both European and American fuel cycle scenarios. Therefore, this work was performed in collaboration Forschungszentrum Jülich (FZJ), and the European SACSESS program. Additionally, results are presented here regarding the radiation of chemistry the non-symmetrical DGA didodecyldioctyldiglycolamide (D3DODGA), for comparison to previous work with symmetrical DGAs such as TODGA and TEHDGA. This was also conducted in collaboration with researchers in the SACSESS program.

  14. Radiation chemistry of aqueous solutions of acetonitrile and propionitrile

    The radiation chemistry of water and aqueous solutions is a branch of radiation chemistry dealing with chemical changes in water and aqueous solutions induced by high energy radiations. High energy radiations of interest in radiation chemistry are short-wave electromagnetic radiations (X- and γ-rays) and fast charged particles (α- and β-particles, electrons, deuterons and fission fragments). The energy of the particles and photons bringing about chemical reactions in the field of modern radiation chemistry is much higher than that of photons causing photochemical reactions

  15. Scavenging and recombination kinetics in radiation chemistry.

    Science.gov (United States)

    Al-Samra, Eyad H; Green, Nicholas J B

    2017-08-02

    This work describes stochastic models developed to study the competition between radical scavenging and recombination for simple model systems typical of radiation chemistry, where the reactive particles are tightly clustered and reactions are assumed fully diffusion limited. Three models are developed: a Monte Carlo random flights model with a periodic boundary condition for scavengers, Monte Carlo simulations in which the scavenging rate is calculated from the Smoluchowski theory for diffusion-limited reactions and a modification of the independent reaction times method where the scavengers close to the spur are explicitly included and the scavengers further away are treated as a continuum. The results indicate that the Smoluchowski theory makes a systematic overestimate of the scavenging rate when such competition is present. A correction for the Smoluchowski rate constant is suggested, an analytical justification is presented and it is tested against the simulations, and shown to be a substantial improvement.

    Full Text Available Objective: To evaluate the quality of models for making removable partial dentures. Methods: In this Study, 140 models were analysed in 05 dental prosthesis laboratories in the city of Teresina, Piauí, Brazil, registered with the Conselho Regional de Odontologia. A form containing 14 closed questions was applied, and the data collected were submitted to statistical analysis using the SPSS program. The models were analysed under natural or artificial light and photographed for record and illustration purposes. Results: The results showed that in 100% of the cases the molding material used was alginate, and 93.43% of the models were poured by the dentist. Of these, 64.47% were poured in stone plaster and 36.43% in special plaster. According to criteria such as surface quality, reproduction of details, presence of bubbles and/or nodules, adequate reproduction of the edentulous area, 78.57% of the models were considered inadequate. The majority of the models (96.43%, were mounted in an articulator by the Dental Laboratory Technician, but only 1 dentist sent the record for mounting the models. The hinge type articulator was used in 97.14% of the mountings. In 94.29% of the cases, the planning and design were not executed by the dentist and in 87.86% of the cases no evidence of mouth preparation was found. In 80% of the cases, communication between the dentist and the Dental Laboratory Technician was done by telephone. Conclusion: Thus it was verified that the removable partial denture continues to be neglected as regards its clinical and laboratorial fabrication, through an excessive transfer of responsibilities from the dentist to the Dental Laboratory Technician and an inefficient communication between the two.

    1982-01-01

    Radiation - chemistry transformations of lower fluorolefines under the effect of #betta# and #betta#-radiations are studied. It is shown that main reaction is radical polymerization characterized by high radiation induced chemical yields. Simultaneously with the polymerization reaction radiolysis of fluorolefines occurs. The radiation polymerization kinetics of tetrafluoroethylene, trifluoroethylene, vinylidene fluoride and vynil fluoride is studied. The radiation-induced fluoroethylene polymerization is shown to proceed in heterogeneous conditions by a radical mechanism. The radiation-induced fluoroethylene polymerization rate changes in the following series: CF 2 =CF 2 >CF 2 =CFH>CF 2 =CH 2 >CFH=CH 2 >CH 2 =CH 2 . Kinetic investigations of graft polymerization of fluoroethylene and ethylene on irradiated polytetrafluoroethylene confirm the discovered order of their polymerizing capacity. Main regularities are observed in the process of radiation-induced fluoroethylene polymerization, which are characterized by a number of particular features specified by the radiation effects, polymerization heterogeneous conditions, and presence of fluorine atoms in a fluoroethylene molecule. These regularities correlate with the quantum chemistry calculation data on fluoroethylene

    There is a growing urgency for forefront basic research on ionizing radiation-induced chemical reactions, due to the relevance of these reactions in such areas of critical national need as environmental waste management, environmental remediation, nuclear energy production, and medical diagnosis and radiation therapy. Fortunately, the emergence of new theoretical and experimental tools for the study of radiation-induced chemical and physical processes, i.e. Radiation Chemistry, makes future progress quite promising. Nevertheless, a recent decline in he number of young investigators in radiation chemistry, as well as a natural obsolescence of large research facilities in radiation chemistry are serious obstacles to further progress. Understanding radiation-induced processes is of vital significance in such diverse fields as waste remediation in environmental cleanup, radiation processing of polymers and food, medical diagnosis and therapy, catalysis of chemical reactions, environmentally benign synthesis, and nuclear energy production. Radiation chemistry provides for these fields fundamental quantitative data, such as reaction rate coefficients, diffusion coefficients, radiation chemical yields, etc. As well as providing useful quantitative information of technological and medical importance, radiation chemistry is also a valuable tool for solving fundamental problems in chemistry and in material sciences. Exploiting the many facets of radiation chemistry requires a thorough and comprehensive understanding of the underlying chemical and physical processes. An understanding of the structure and dynamics of “tracks” produced by ionizing radiation is a central issue in the field. There is a continuing need to study the ultrafast processes that link the chemistry and physics of radiation-induced phenomena. This is especially true for practically important, but less well understood, nonstandard environments such as interfacial systems, supercritical media, and

    1996-01-01

    Full text: TFE/PMVE (tetrafluoroethylene/perfluoromethylvinyl ether) is a commercial perfluoroelastomer marketed by the Du Pont Company under the trade-name Kalrez. Very little is known about the radiation chemistry of this fluoropolymer which in general is consistent with all fluoropolymers. In 1984, Uschold, while attempting to graft vinyl monomers onto irradiated TFE/PMVE, found that the fluoroelastomer crosslinked forming and insoluble network. Unfortunately, Uschold found that the mechanical properties of irradiated TFE/PMVE were inferior when compared to the chemically crosslinked analogues because of the simultaneous radiation scissioning of the polymer chain. This chemical curing is described elsewhere. The radiation crosslinking of TFE/PMVE was also briefly studied by Luo et al. and later by Sun et al. but they exclusively looked at the sol/gel behaviour. Recently Lyons reviewed the radiation chemistry of fluoropolymers and showed that most research solely focused on the physical properties of the cured material and little attention placed on the development of mechanisms of radiation chemistry. In this study, we have employed both physical and chemical techniques such as tensile tests and 19 F NMR to formulate a radiation mechanism describing both chain scission and crosslinking processes. 19 F NMR identified and quantified new functionalities such as carboxylic acid and saturated chain ends. The crosslinking reaction has been tentatively postulated for the first time. Factors affecting the radiation chemistry such as the presence of oxygen and irradiation temperature will be briefly discussed

  8. Radiation chemistry and origins of life on earth

    International Nuclear Information System (INIS)

    Zagorski, Z.P.

    2002-01-01

    Complete text of publication follows. Radiation chemistry is involved in mechanisms of origins of life on Earth in three aspects: 1. The formation of prebiotic 'soup' of organic compounds related to future life, 2. Possible role in formation of pure enantiomers of chiral compounds, 3. Role in rejection of hypothesis of Life transported from the outside worlds (Panspermia). As concerns 1, radiation chemistry explains better the formation of proper prebiotic 'soup' than Miller hypothesis of electric discharges in gaseous atmosphere. Radiation-induced reactions proceeded in liquid phase, also in the presence of solid state and as specific surface reactions, all at the ambient temperature. As concerns 2, radiation chemistry offers limited possibilities, but papers still are published to that effect and efforts are needed to tell facts from artifacts. As concerns 3, radiation chemistry and its cousin - radiobiology speak out definitively, that any transportation of life, even of low organisation, from the outer space is impossible. The main reason is irreversible dehydrogenation even at very low temperatures, during the travel lasting for years and light-years. The same applies in higher degree to the well organised life, making an appearance of 'ET' on Earth not likely. Even the manned travels to Mars and living in houses at the surface, can end with radiation sickness and premature death

    This report summarizes work accomplished under the Fuel Cycle Research and Development (FCR&D) program in the area of radiation chemistry during FY 2011. The tasks assigned during FY 2011 included: (1) Continue measurements free radical reaction kinetics in the organic phase; (2) Continue development of an alpha-radiolysis program and compare alpha and gamma radiolysis for CMPO; (3) Initiate an effort to understand dose rate effects in radiation chemistry; and (4) Continued work to characterize TALSPEAK radiation chemistry, including the examination of metal complexed ligand kinetics. Progress made on each of these tasks is reported here. Briefly, the method developed to measure the kinetics of the reactions of the NO3 radical with solvent extraction ligands in organic solution during FY10 was extended here to a number of compounds to better understand the differences between radical reactions in the organic versus aqueous phases. The alpha-radiolysis program in FY11 included irradiations of CMPO solutions with 244Cm, 211At and the He ion beam, for comparison to gamma irradiations, and a comparison of the gamma irradiation results for CMPO at three different gamma dose rates. Finally, recent results for TALSPEAK radiolysis are reported, summarizing the latest in an effort to understand how metal complexation to ligands affects their reaction kinetics with free radicals.

    2010-07-23

    The 2010 Gordon Conference on Radiation Chemistry will present cutting edge research regarding the study of radiation-induced chemical transformations. Radiation Chemistry or 'high energy' chemistry is primarily initiated by ionizing radiation: i.e. photons or particles with energy sufficient to create conduction band electrons and 'holes', excitons, ionic and neutral free radicals, highly excited states, and solvated electrons. These transients often interact or 'react' to form products vastly different than those produced under thermal equilibrium conditions. The non-equilibrium, non-thermal conditions driving radiation chemistry exist in plasmas, star-forming regions, the outer solar system, nuclear reactors, nuclear waste repositories, radiation-based medical/clinical treatment centers and in radiation/materials processing facilities. The 2010 conference has a strong interdisciplinary flavor with focus areas spanning (1) the fundamental physics and chemistry involved in ultrafast (atto/femtosecond) energy deposition events, (2) radiation-induced processes in biology (particularly spatially resolved studies), (3) radiation-induced modification of materials at the nanoscale and cosmic ray/x-ray mediated processes in planetary science/astrochemistry. While the conference concentrates on fundamental science, topical applied areas covered will also include nuclear power, materials/polymer processing, and clinical/radiation treatment in medicine. The Conference will bring together investigators at the forefront of their field, and will provide opportunities for junior scientists and graduate students to present work in poster format or as contributors to the Young Investigator session. The program and format provides excellent avenues to promote cross-disciplinary collaborations.

    Among all the environmental hazards to which man is exposed, ionizing radiation is the most thoroughly investigated and the most responsibly monitored and controlled. Nevertheless, because of the importance of radiation in modern society from both the hazard as well as the utilitarian standpoints, much more information concerning the biological effects induced and their modification and reversal is required. Together with radiation physics, an understanding of radiation chemistry is necessary for full appreciation of biological effects of high and low energy radiations, and for the development of prophylactic, therapeutic and potentiating methods and techniques in biological organisms. The necessity of understanding the chemistry of any system, biological or not, that is to be manipulated and controlled, is so obvious as to make trivial a statement to that effect. If any natural phenomenon is to be put to our use, surely the elements of it must be studied and appreciated fully. In the preliminary statements of the various panels of this general group, the need for additional information on the basic radiation chemistry concerned in radiation-induced biological effects pervades throughout

    Salicylic acid and its derivatives are components of many medications and moieties found in numerous pharmaceutical compounds. They have been used as models for various pharmaceutical compounds in pharmacological studies, for the treatment of pharmaceuticals and personal care products (PPCPs), and, reactions with natural organic matter (NOM). In this study, the radiation chemistry of benzoic acid, salicylic acid and four methyl substituted salicylic acids (MSA) is reported. The absolute bimolecular reaction rate constants for hydroxyl radical reaction with benzoic and salicylic acids as well as 3-methyl-, 4-methyl-, 5-methyl-, and 6-methyl-salicylic acid were determined (5.86±0.54)×10 9 , (1.07±0.07)×10 10 , (7.48±0.17)×10 9 , (7.31±0.29)×10 9 , (5.47±0.25)×10 9 , (6.94±0.10)×10 9 (M −1 s −1 ), respectively. The hydrated electron reaction rate constants were measured (3.02±0.10)×10 9 , (8.98±0.27)×10 9 , (5.39±0.21)×10 9 , (4.33±0.17)×10 9 , (4.72±0.15)×10 9 , (1.42±0.02)×10 9 (M −1 s −1 ), respectively. The transient absorption spectra for the six model compounds were examined and their role as model compounds for the radiation chemistry of pharmaceuticals investigated. - Highlights: • Free radical chemistry of salicylic and 4 methyl salicylic acids is investigated. • The transient absorptions spectra for model compounds are measured. • Absolute bimolecular reaction rate constants for hydroxyl radical are determined. • Solvated electron reaction rate constants are calculated. • The use of salicylic acids as models for pharmaceuticals is explored

  6. Ionic Liquids: Radiation Chemistry, Solvation Dynamics and Reactivity Patterns

    International Nuclear Information System (INIS)

    Wishart, J.F.

    2011-01-01

    Ionic liquids (ILs) are a rapidly expanding family of condensed-phase media with important applications in energy production, nuclear fuel and waste processing, improving the efficiency and safety of industrial chemical processes, and pollution prevention. ILs generally have low volatilities and are combustion-resistant, highly conductive, recyclable and capable of dissolving a wide variety of materials. They are finding new uses in chemical synthesis, catalysis, separations chemistry, electrochemistry and other areas. Ionic liquids have dramatically different properties compared to conventional molecular solvents, and they provide a new and unusual environment to test our theoretical understanding of primary radiation chemistry, charge transfer and other reactions. We are interested in how IL properties influence physical and dynamical processes that determine the stability and lifetimes of reactive intermediates and thereby affect the courses of reactions and product distributions. We study these issues by characterization of primary radiolysis products and measurements of their yields and reactivity, quantification of electron solvation dynamics and scavenging of electrons in different states of solvation. From this knowledge we wish to learn how to predict radiolytic mechanisms and control them or mitigate their effects on the properties of materials used in nuclear fuel processing, for example, and to apply IL radiation chemistry to answer questions about general chemical reactivity in ionic liquids that will aid in the development of applications listed above. Very early in our radiolysis studies it became evident that the slow solvation dynamics of the excess electron in ILs (which vary over a wide viscosity range) increase the importance of pre-solvated electron reactivity and consequently alter product distributions and subsequent chemistry. This difference from conventional solvents has profound effects on predicting and controlling radiolytic yields

  7. Radiation chemistry of heavy-particle tracks. I. General considerations

    International Nuclear Information System (INIS)

    Magee, J.L.; Chatterjee, A.

    1980-01-01

    The radiation chemistry of heavy-particle tracks in dilute aqueous solution is considered in a unified manner. Emphasis is on the physical and chemical phenomena which are involved rather than on the construction of models to be used in actual calculations although the latter problem is discussed. A differential segment of a heavy-particle track is composed of two parts which we call core and penumbra; elementary considerations show that all properties of such a differential track can be uniquely specified in terms of a two-parameter system, and we choose energy per nucleon (E) and atomic numbers (Z) as independent parameters. The nature of heavy-particle-track processes varies with the magnitude of the energy deposit (LET), and we discuss three categories of track problems, for low-, intermediate-, and high-LET cases, respectively. Scavenger reactions normally terminate radical recombination in a track, and for heavy-particle tracks we find a criterion involving the scavenger concentration for a convenient separation of core and penumbra into essentially noninteracting parts which can be treated independently. Problems of the core expansion in the three regions are considered, and it is found that a versatile model can be constructed on concepts previously introduced by Ganguly and Magee.

    The electron beam process, an advanced oxidation and reduction technology, is based in the field of radiation chemistry. Fundamental to the development of treatment processes is an understanding of the underlying chemistry. The authors have previously evaluated the bimolecular rate constants for the reactions of methyl tert-butyl ether (MTBE) and with this study have extended their studies to include ethyl tert-butyl ether (ETBE), di-isopropyl ether (DIPE) and tert-amyl methyl ether (TAME) with the hydroxyl radical, hydrogen atom and solvated electron using pulse radiolysis. For all of the oxygenates the reaction with the hydroxyl radical appears to be of primary interest in the destruction of the compounds in water. The rates with the solvated electron are limiting values as the rates appear to be relatively low. The hydrogen atom rate constants are relatively low, coupled with the low yield in radiolysis, they concluded that these are of little significance in the destruction of the alternative fuel oxygenates (and MTBE)

    Complete text of publication follows. There are a lot of experimental evidences suggesting that the primary radiation-induced events in organic solids and polymers are highly selective and sensitive to conformation, molecular packing, matrix environment, etc. Nevertheless, specific 'selection rules' in the radiation chemistry of molecules in solids are still not established. This contribution presents a review of our recent studies of the radiation damage in organic molecules in low-temperature matrices and polymers aimed at elucidation of basic physical factors controlling selectivity of the primary chemical events. The following aspects will be analyzed: 1. 'Fine tuning' effects in positive hole trapping in rigid systems containing molecular 'traps' with close ionization energy. 2. Selective chemical bond weakening in ionized molecules: experimental and theoretical results. 3. Matrix-assisted and matrix-controlled chemical reactions of ionized molecules in solid media (including the effect of 'matrix-catalysis'). 4. Effect of excess energy on the fate of ionized molecules in solid matrices: the role of intramolecular and intermolecular relaxation. Finally, the problem of experimental and theoretical simulation of the distribution of the radiation-induced events in complex molecular systems and polymers will be addressed

    Radiation chemistry acts as a bridge connecting radiation physics with radiation biology in spatial and temporal insight. The theory, model, and methodology coming from radiation chemistry play an important role in the research and development of radiation biology. The chemical changes induced by ionizing radiation are involved not only in early event of biological effects caused by ionizing radiation but in function radiation biology, such as DNA damage and repair, sensitive modification, metabolism and function of active oxygen and so on. Following the research development of radiation biology, systems radiation biology, accurate quality and quantity of radiation biology effects need more methods and perfect tools from radiation chemistry.

    One hundred and seventy-eight dental laboratory technicians and 69 non-exposed controls participated in an epidemiological respiratory study. Eight technicians who had a mean of 28 years grinding nonprecious metal alloys were diagnosed as having a simple pneumoconiosis by chest radiograph. Mean values for per cent predicted FVC and FEV1 were reduced among male nonsmoker technicians compared to male nonsmoker controls; after controlling for age, there was also a reduction in spirometry with increasing work-years. An industrial hygiene survey was conducted in 13 laboratories randomly selected from 42 laboratories stratified by size and type of operation in the Salt Lake City, Utah metropolitan area. Personal exposures to beryllium and cobalt exceeded the Threshold Limit Values (TLVs) in one laboratory. Occupational exposures in dental laboratories need to be controlled to prevent beryllium-related lung disorders as well as simple pneumoconiosis

    Ionic liquids (ILs) are a rapidly expanding family of condensed-phase media with important applications in energy production, nuclear fuel and waste processing, improving the efficiency and safety of industrial chemical processes, and pollution prevention. ILs are generally nonvolatile, noncombustible, highly conductive, recyclable and capable of dissolving a wide variety of materials. They are finding new uses in chemical synthesis, catalysis, separations chemistry, electrochemistry and other areas. Ionic liquids have dramatically different properties compared to conventional molecular solvents, and they provide a new and unusual environment to test our theoretical understanding of charge transfer and other reactions. We are interested in how IL properties influence physical and dynamical processes that determine the stability and lifetimes of reactive intermediates and thereby affect the courses of chemical reactions and product distributions. Successful use of ionic liquids in radiation-filled environments, where their safety advantages could be significant, requires an understanding of ionic liquid radiation chemistry. For example, characterizing the primary steps of IL radiolysis will reveal radiolytic degradation pathways and suggest ways to prevent them or mitigate their effects on the properties of the material. An understanding of ionic liquid radiation chemistry will also facilitate pulse radiolysis studies of general chemical reactivity in ILs, which will aid in the development of applications listed above. Very early in our radiolysis studies it became evident that slow solvation dynamics of the excess electron in ILs (which vary over a wide viscosity range) increases the importance of pre-solvated electron reactivity and consequently alters product distributions. Parallel studies of IL solvation phenomena using coumarin-153 dynamic Stokes shifts and polarization anisotropy decay rates are done to compare with electron solvation studies and to evaluate

  19. The radiation chemistry of aqueous sodium terephthalate solutions

    International Nuclear Information System (INIS)

    Matthews, R.W.

    1980-04-01

    The radiation chemistry of cobalt-60 gamma-irradiated aqueous sodium terephthalate solutions has been studied. In aerated 4 x 10 -4 M sodium hydroxide solutions, the main products are hydroxyterephthalate (HTA) (G = 0.99 +- 0.01), carbonate (G = 1.31 +- 0.08), and peroxides (G = 2.84 +- 0.04). The HTA and carbonate species are both formed as a result of hydroxyl radical attack and account for approximately 90 per cent of hydroxyl radical reactions. Oxygen needs to be present for efficient conversion of the terephthalate-OH radical adduct to HTA and oxygenation increases G(HTA) above the aerated solution value. G(HTA) is unaffected by changes in terephthalate concentration between 1 x 10 -4 M and 1 x 10 -2 M in sodium hydroxide solutions at pH 10. Decreasing the solution pH does however affect G(HTA). In phosphate buffered solutions pH 6.85, G(HTA) is 0.93 +- 0.01 and lower values are obtained with further decrease in solution pH. The lowering of the G(HTA) value is attributed to recombination reactions between the terephthalate-OH radical products and reducing radical products. Experimental evidence supporting the recombination postulate was obtained from the measurement of a parallel decrease in the peroxide yield and the observation of a dose rate effect on G(HTA). Competition kinetic studies with the added solutes carbonate and bicarbonate gave the rate ratios k (OH + TA 2- ) : k(OH + CO 3 2- ) : k(OH + HCO 3 - ) = 1 : 0.105 : 0.0036

    Certain aspects of the radiation chemistry of NaCl-saturated MgCl 2 solutions and MgCl 2 hydrates at temperatures in the range of 30 to 180 0 C were investigated through experiments. A principal objective was to establish the values for the yields of H 2 [G(H 2 )] and accompanying oxidants in the gamma-ray radiolysis of concentrated brines that might occur in waste repositories in salt. We concluded that G(H 2 ) from gamma-irradiated brine solution into a simultaneously irradiated, deaerated atmosphere above the solution is between 0.48 and 0.49 over most of the range 30 to 143 0 C. The yield is probably somewhat lower at the lower end of this range, averaging 0.44 at 30 to 45 0 C. Changes in the relative amounts of MgCl 2 and NaCl in the NaCl-saturated solutions have negligible effects on the yield. The yield of O 2 into the same atmosphere averages 0.13, independent of the temperature and brine composition, showing that only about 50% of the radiolytic oxidant that was formed along with the H 2 was present as O 2 . We did not identify the species that compose the remainder of the oxidant. We concluded that the yield of H 2 from a gamma-irradiated brine solution into a simultaneously irradiated atmosphere containing 5 to 8% air in He may be greater than the yield in deaerated systems by amounts ranging from 0% for temperatures of 73 to 85 0 C, to about 30 and 40% for temperatures in the ranges 100 to 143 0 C and 30 to 45 0 C, respectively. We did not establish the mechanism whereby the air affected the yields of H 2 and O 2 . The values found in this work for G(H 2 ) in deaerated systems are in approximate agreement with the value of 0.44 for the gamma-irradiation yield of H 2 in pure H 2 O at room temperature. They are also in agreement with the values predicted by extrapolation from the findings of previous researchers for the value for G(H 2 ) in 2 M NaCl solutions at room temperature

Pulse radiolysis of [R 4 N][NTf 2 ] [R 4 N][N(CN) 2 ], and [R 4 P][N(CN) 2 ] ionic liquids produces solvated electrons that absorb over a broad range in the near infrared and persisting for hundreds of nanoseconds. Systematic cation variation shows that solvated electron's spectroscopic properties depend strongly on the lattice structure of the ionic liquid.

    Radiation chemistry is a part of the physical chemistry similarly like photo-chemistry, plasma-chemistry, ultrasonic-chemistry etc. Ionizing radiation produces abundant secondary electrons. Following these primary events, the ions, secondary electrons and excited molecules undergo further transformations, exchanging charges and energy and reacting with surrounding molecules, thereby producing free radicals and other reactive species which finally evolve into new stable products. Three main sources of radiation are applied for radiation processing. These are electron accelerators, gamma sources and X-ray unit based on e-/X conversion process. Radiation processing was used early on for polymer modification. The intermediates formed during material irradiation can follow several reaction paths that result in disproportion, hydrogen abstraction, arrangements and/or the formation of new bonds. Nowadays, the modification of polymers covers radiation cross-linking, radiation-induced polymerization (graft polymerization and curing) and the degradation of polymers. Some polymers predominantly undergo crosslinking other degradation. However new techniques allow crosslinking of polymers which were considered to be degradable only, like PTFE and cellulose derivatives. Regarding natural polymers the biggest application concerns rubber pre-crosslinking in tire industry. The processing of natural polymers is also being developed to elaborate new biodegradable materials. The radiation crosslinked wires and cables show excellent heat resistance (long-term thermal stability and short-term thermal stability) as well as abrasion resistance. Other big application is crosslinking of XLPE type pipes which are widely used for hot water and floor heating [30]. Polybutelene terephthalate (PBT), which is a plastic for electronic industry, can be crosslinked by radiation and lead free soldering materials can be applied in such a case. This method of crosslinking is also applied to manufacture

    Time-resolved pulsed EPR and ODMR in studies on early events in radiation chemistry are examined. It is concluded that these techniques yield valuable and diverse information about chemical reactions in spurs, despite the fact that the spur reactions occur on a time scale that is much shorter than the time resolution of these methods. Several recent examples include EPR of H/D atoms in vitreous silica and cryogenic liquids and ODMR of doped alkane solids and amorphous semiconductors. It is argued that a wider use of time-resolved magnetic resonance methods would benefit the studies on radiation chemistry of disordered solids, simple liquids, and polymers. (author)

    The development of an innovative role for the pharmacy technician is described. The role of the pharmacy technician was based on a needs assessment and the expertise of the pharmacy technician selected. Initial responsibilities of the technician included chart reviews, benchmarking surveys, monthly financial impact analysis, initiative assessment, and quality improvement reporting. As the drug-use and disease-state management (DUDSM) program expanded, pharmacist activities increased, requiring the expansion of data analyst technician (DAT) duties. These new responsibilities included participation in patient assessment, data collection and interpretation, and formulary enforcement. Most recently, technicians' expanded duties include maintenance of a physician compliance profiling database, quality improvement reporting and graphing, active role in patient risk assessment and database management for adult vaccination, and support of financial impact monitoring for other institutions within the health system. This pharmacist-technician collaboration resulted a threefold increase in patient assessments completed per day. In addition, as the DUDSM program continues to expand across the health system, an increase in DAT resources from 0.5 to 1.0 full-time equivalent was obtained. The role of the DAT has increased the efficiency of the DUDSM program and has provided an innovative role for the pharmacy technician.

    This paper reports on Nuclear Instrument Technician (NIT) training that has developed at an accelerated rate over the past three decades. During the 1960's commercial nuclear power plants were in their infancy. For that reason, there is little wonder that NIT training had little structure and little creditability. NIT training, in many early plants, was little more than On-The Job Training (OJT). The seventies brought changes in Instrumentation and Controls as well as emphasis on the requirements for more in depth training and documentation. As in the seventies, the eighties saw not only changes in technologies but tighter requirements, standardized training and the development of accredited Nuclear Instrument Training; thus the conclusion: Nuclear Instrument Training Isn't What It Used To Be

  9. Should Pharmacy Technicians Administer Immunizations?

    Directory of Open Access Journals (Sweden)

    2017-09-01

    Full Text Available Purpose. To describe the potential role for pharmacy technicians in administering immunizations – limited for this discussion to specifically inserting the needle into the patient’s arm and pressing down on the plunger – at the discretion of a supervising pharmacist as a way to enhance patient care and workflow efficiency. Summary. Pharmacy technicians currently play an important role in facilitating pharmacy-based immunization programs. Technicians routinely perform non-clinical tasks related to pharmacy-based immunizations, though nearly all states prohibit technicians from administering vaccines. Several studies demonstrate that untrained laypersons can safely administer intranasal or intradermal vaccines, and laypersons routinely administer medications through intramuscular or subcutaneous routes (e.g., patients with diabetes or rheumatic conditions. It stands to reason that a trained pharmacy technician could perform comparably on these techniques that laypersons have mastered. One state has adopted rules to allow pharmacy technicians to administer immunizations if the technician has completed specific training on administration techniques and on basic life support. This task is performed at the discretion of the supervising pharmacist, and the pharmacist would still be responsible for clinical aspects of immunizing such as prescribing the right vaccine to the right patient. Additional considerations factoring into the decision as to whether or not to involve pharmacy technicians in immunization administration are also summarized. Conclusion. If safety can be reasonably assured through training and supervision, it may be appropriate to delegate vaccine administration to appropriately trained pharmacy technicians. Such delegation may enhance workflow efficiency, which may confer added value for patient care and potentially improve access to community pharmacy-based immunizations.   Type: Commentary

    This book gives a progress report on the many and original contributions of radiation chemistry to the fundamental knowledge of the vast domain of chemical reactions and its applications. Radiation chemistry techniques indeed make it possible to elucidate detailed physicochemical mechanisms in inorganic and organic chemistry (including in space) and in biochemistry. Moreover, this comprehension is applied in materials science to precisely control syntheses by radiation, such as radiopolymerization, radio-grafting, specific treatment of surfaces (textiles, paintings, inks,..), synthesis of complex nano-materials, degradation of environmental pollutants and radioresistance of materials for nuclear reactors. In life sciences, the study of the effects of radiation on bio-macromolecules (DNA, proteins, lipids) not only permits the comprehension of normal or pathological biological mechanisms, but also the improvement of our health. In particular, many advances in cancer radiotherapy, in the radioprotection of nuclear workers and the general population, as well as in the treatment of diseases and the radiosterilization of drugs, could be obtained thanks to this research. Abundantly illustrated and written in English by top international specialists who have taken care to render the subjects accessible, this work will greatly interest those curious about a scientific field that is new to them and students attracted by the original and multidisciplinary aspects of the field. At a time when radiation chemistry research is experiencing spectacular development in numerous countries, this book will attract newcomers to the field. (authors)

    The Oak Ridge National Laboratory (ORNL) is currently involved in extensive environmental monitoring activities to characterize various active/inactive waste sites that exist at the facility. There are also considerable reporting requirements that ORNL must meet on a continuing basis in order to remain in compliance with existing permit requirements under the Resource Conservation and Recovery Act (RCRA), the Clean Air Act (CAA), and the Clean Water Act (CWA). Much of the environmental monitoring data that is used to characterize waste sites or is required in reports is obtained by environmental sampling technicians who must take samples at various locations throughout ORNL as well as other DOE installations. Because of the quality control and assurance measures included under NQA-1, ORNL has developed an Environmental Sampling Technician Training program. This presentation will describe how the Environmental Sampling Technician Training Program was developed and review the specific materials used in conducting the training

  8. Considerations for the independent reaction times and step-by-step methods for radiation chemistry simulations

    Ionizing radiation interacts with the water molecules of the tissues mostly by ionizations and excitations, which result in the formation of the radiation track structure and the creation of radiolytic species such as H.,.OH, H2, H2O2, and e-aq. After their creation, these species diffuse and may chemically react with the neighboring species and with the molecules of the medium. Therefore radiation chemistry is of great importance in radiation biology. As the chemical species are not distributed homogeneously, the use of conventional models of homogeneous reactions cannot completely describe the reaction kinetics of the particles. Actually, many simulations of radiation chemistry are done using the Independent Reaction Time (IRT) method, which is a very fast technique to calculate radiochemical yields but which do not calculate the positions of the radiolytic species as a function of time. Step-by-step (SBS) methods, which are able to provide such information, have been used only sparsely because these are time-consuming in terms of calculation. Recent improvements in computer performance now allow the regular use of the SBS method in radiation chemistry. The SBS and IRT methods are both based on the Green's functions of the diffusion equation (GFDE). In this paper, several sampling algorithms of the GFDE and for the IRT method are presented. We show that the IRT and SBS methods are exactly equivalent for 2-particles systems for diffusion and partially diffusion-controlled reactions between non-interacting particles. We also show that the results obtained with the SBS simulation method with periodic boundary conditions are in agreement with the predictions by classical reaction kinetics theory, which is an important step towards using this method for modelling of biochemical networks and metabolic pathways involved in oxidative stress. Finally, the first simulation results obtained with the code RITRACKS (Relativistic Ion Tracks) are presented.

  9. The radiation chemistry of some poly(arylene phosphene oxide)s

    International Nuclear Information System (INIS)

    The poly(arylene phosphene oxide)s are a class of thermoplastics with high glass transition temperature, high modulus and inherent flame retardancy. These properties make them good candidates for use in high energy radiation environments, such as occur in space and in the nuclear industry. In this paper the high energy radiation chemistry of a series of these polymers will be discussed, including studies of the radicals formed, the molecular weight changes and the changes in chemical structure evident through NMR spectroscopy. The radiation sensitivity of the polymers will be compared with that of the related poly(arylene sulfone)s and poly(arylene ether ether ketone)s

    Radiolytic species are formed approximately 1 ps after the passage of ionizing radiation through matter. After their formation, they diffuse and chemically react with other radiolytic species and neighboring biological molecules, leading to various oxidative damage. Therefore, the simulation of radiation chemistry is of considerable importance to understand how radiolytic species damage biological molecules [1]. The step-by-step simulation of chemical reactions is difficult, because the radiolytic species are distributed non-homogeneously in the medium. Consequently, computational approaches based on Green functions for diffusion-influenced reactions should be used [2]. Recently, Green functions for more complex type of reactions have been published [3-4]. We have developed exact random variate generators of these Green functions [5], which will allow us to use them in radiation chemistry codes. Moreover, simulating chemistry using the Green functions is which is computationally very demanding, because the probabilities of reactions between each pair of particles should be evaluated at each timestep [2]. This kind of problem is well adapted for General Purpose Graphic Processing Units (GPGPU), which can handle a large number of similar calculations simultaneously. These new developments will allow us to include more complex reactions in chemistry codes, and to improve the calculation time. This code should be of importance to link radiation track structure simulations and DNA damage models.

    Positronium formation in cyclohexane has been studied using C 2 H 5 Br or CCl 4 as an inhibitor and C 6 F 6 as an anti-inhibitor. The results are analyzed using an empirical formula which is well established in radiation chemistry for electron scavenging reactions in cyclohexane. The reactivity parameters derived from the radiation chemistry are shown to successfully reproduce the experimental results. Very close correlation between positronium formation and radiation chemistry is evident, and the spur reaction model of positronium formation is corroborated. From a simple model of the positron spur in which only a single ion pair and a positron is assumed, it is estimated that about 75% of the spur electron combines with the positron. (author)

    The irradiation of biological systems leads to the formation of radiolytic species such as H(raised dot), (raised dot)OH, H2, H2O2, e(sup -)(sub aq), etc.[1]. These species react with neighboring molecules, which result in damage in biological molecules such as DNA. Radiation chemistry is there for every important to understand the radiobiological consequences of radiation[2]. In this work, we discuss an approach based on the exact Green Functions for diffusion-influenced reactions which may be used to simulate radiation chemistry and eventually extended to study more complex systems, including DNA.

    To evaluate the effectiveness of an immunization training program for pharmacy technicians on technicians' self-reported confidence, knowledge, and number of vaccines administered. A one-group pre- and posttest study was conducted with certified pharmacy technicians from Albertsons and Safeway community pharmacies in Idaho. Thirty pharmacy technicians were recruited to participate in an immunization administration training program comprising a 2-hour home study and a 2-hour live training. Pharmacy technician scores on a 10-question knowledge assessment, responses on a pre- and posttraining survey, and number of immunizations administered in the 6-month period following the training were collected. Twenty-five pharmacy technicians completed the home study and live portions of the immunization training program. All 29 pharmacy technicians who took the home study assessment passed with greater than 70% competency on the first attempt. Technicians self-reported increased confidence with immunization skills between the pretraining survey and the posttraining survey. From December 2016 to May 2017, the technicians administered 953 immunizations with 0 adverse events reported. For the first time, pharmacy technicians have legally administered immunizations in the United States. Trained pharmacy technicians demonstrated knowledge of vaccination procedures and self-reported improved confidence in immunization skills and administered immunizations after participating in a 4-hour training program.

    Radiation Chemistry is chemistry initiated by ionizing radiation: i.e. photons or particles with energy sufficient to create charge pairs and/or free radicals in a medium. The important transients include conduction band electrons and 'holes', excitons, ionic and neutral free radicals, highly excited states, and solvated electrons. Effects of radiation span timescales from the energy deposition in femtoseconds, through geminate recombination in picoseconds and nanoseconds, to fast radical chemistry in microseconds and milliseconds, and ultimately to processes like cancer occurring decades later. The radiation sources used to study these processes likewise run from femtosecond lasers to nanosecond accelerators to years of gamma irradiation. As a result the conference has a strong interdisciplinary flavor ranging from fundamental physics to clinical biology. While the conference focuses on fundamental science, application areas highlighted in the present conference will include nuclear power, polymer processing, and extraterrestrial chemistry.

    In this paper, we propose a general formalism that allows for the estimation of radiolysis decomposition pathways and rate coefficients suitable for use in astrochemical models, with a focus on solid phase chemistry. Such a theory can help increase the connection between laboratory astrophysics experiments and astrochemical models by providing a means for modelers to incorporate radiation chemistry into chemical networks. The general method proposed here is targeted particularly at the majority of species now included in chemical networks for which little radiochemical data exist; however, the method can also be used as a starting point for considering better studied species. We here apply our theory to the irradiation of H 2 O ice and compare the results with previous experimental data.

    Supramolecular chemistry, one of the front fields in chemistry, is defined as 'chemistry beyond the molecule', bearing on the organized entities of higher complexity that result from the association of two or more chemical species held together by intermolecular forces. This article focuses on the application of the principle of supramolecular chemistry in the fields of radiochemistry and radiation chemistry. The following aspects are concerned: (1) the recent progress of supramolecular chemistry; (2) the application of the principle of supramolecular chemistry and the functions of supramolecular system, i.e., recognition, assembly and translocation, in the extraction of nuclides; (3) the application of microemulsion, ionic imprinted polymers, ionic liquids and cloud point extraction in the enrichment of nuclides; (4) the radiation effect of supramolecular systems.

  3. Bibliographies on radiation chemistry: II. Studies of the chemistry of semiquinones

    Science.gov (United States)

    Swallow, A. John; Ross, Alberta B.; Helman, W. Phillip

    It has been known for half a century that the interconversion between quinones and hydroquinones is capable of proceeding through the formation of highly resonance-stabilized free radical intermediates called semiquinones. These semiquinones play a vital role in many processes including the biologically important processes of photosynthesis and mitochondrial electron transport. By the 1950s and 1960s, radiation chemistry and photochemistry had developed sufficiently for techniques such as pulse radiolysis and flash photolysis to be used to obtain reliable quantitative information about the chemistry of organic free radicals, and semiquinones were among the first to be studied. This bibliography (1) lists about 280 papers dealing with the formation, properties and reactions of free radicals containing the 1 ,2- or 1 ,4-benzosemiquinone moiety. Related species such as those prepared from camphorquinone, quinone methides and aromatic compounds like flavins and certain dyestuffs are excluded. The bibliography is almost completely confined to studies of semiquinones produced in irradiated systems. Chemical, biological and electrochemical generation of the intermediates are not covered. Papers on reduction of quinones or oxidation of hydroquinones containing no quantitative information on the semiquinone intermediates are likewise not included. The bibliography was prepared by a search of the Radiation Chemistry Data Center bibliographic data base using the keywords semiquinones, quinones, hydroquinones, pulse radiolysis and flash photolysis. The keywords gamma rays (radiolysis), photolysis and quinones also yielded some pertinent references, and inspection of several reviews and the cited references in a few papers revealed additional references. While earlier references known to the authors have been included, the bibliography mainly contains references since 1970 and coverage extends through August, 1980. The references are listed in approximately chronological order

    1980-01-01

    The technician has a responsible role to fulfil in nuclear industry, acting as a bridge between the engineer and the skilled worker. Technicians must have sufficient theoretical knowledge to communicate with engineers, and a thorough understanding of technological practice; the nuclear industry demands both theory and practice of a high standard. In Brazil the essential role of the technician in industry is in general recognized. However, the lack of a nationally recognized Nuclear Technician and Nuclear Technologist qualification, as well as a desire of the best technicians to quality as engineers and, in some areas, inadequate salaries has resulted in a shortage of well-trained technicians. A first step to ensure availability of these technicians is to improve their career prospects and status through definition of appropriate career standards and salaries. Practical training by the industry can only be given in factories, plants and construction sites where nuclear work is done. It is proposed to extend apprentice training centres at three sites, to give the most promising students after two years of apprentice training two further years of instruction and practice to qualify as Nuclear Technicians. The training centres are chosen to cover the three sectors of nuclear industry where special training of technicians is important: manufacture and construction; operation and maintenance; and testing and analysis for process control and safety.

  6. A Radiation Chemistry Code Based on the Greens Functions of the Diffusion Equation

    Science.gov (United States)

    Plante, Ianik; Wu, Honglu

    2014-01-01

    Ionizing radiation produces several radiolytic species such as.OH, e-aq, and H. when interacting with biological matter. Following their creation, radiolytic species diffuse and chemically react with biological molecules such as DNA. Despite years of research, many questions on the DNA damage by ionizing radiation remains, notably on the indirect effect, i.e. the damage resulting from the reactions of the radiolytic species with DNA. To simulate DNA damage by ionizing radiation, we are developing a step-by-step radiation chemistry code that is based on the Green's functions of the diffusion equation (GFDE), which is able to follow the trajectories of all particles and their reactions with time. In the recent years, simulations based on the GFDE have been used extensively in biochemistry, notably to simulate biochemical networks in time and space and are often used as the "gold standard" to validate diffusion-reaction theories. The exact GFDE for partially diffusion-controlled reactions is difficult to use because of its complex form. Therefore, the radial Green's function, which is much simpler, is often used. Hence, much effort has been devoted to the sampling of the radial Green's functions, for which we have developed a sampling algorithm This algorithm only yields the inter-particle distance vector length after a time step; the sampling of the deviation angle of the inter-particle vector is not taken into consideration. In this work, we show that the radial distribution is predicted by the exact radial Green's function. We also use a technique developed by Clifford et al. to generate the inter-particle vector deviation angles, knowing the inter-particle vector length before and after a time step. The results are compared with those predicted by the exact GFDE and by the analytical angular functions for free diffusion. This first step in the creation of the radiation chemistry code should help the understanding of the contribution of the indirect effect in the

  7. A review of the radiation chemistry of iodine compounds in aqueous solution

    International Nuclear Information System (INIS)

    Sellers, R.M.

    1977-06-01

    Large amounts of radioactive iodine are formed in the fission of uranium in nuclear reactors. Some of this may be released to the coolant from the fuel either by diffusion through the canning material, or following the failure of a fuel pin. The iodine, which is released mainly as I 2 and methyl iodide, is transported with the coolant and, in direct cycle water cooled reactors, some is carried over with the steam to the turbines, where contamination may build up in the vicinity of steam leaks. Any assessment of the mechanism of the transport of iodine requires a knowledge of the relative amounts of the various oxidation states present, and must consider not only the thermal behaviour of iodine in water, but also the radiation chemical effects. A review is presented of the radiation chemistry of inorganic iodine compounds and methyl iodide in aqueous solutions. A number of unstable intermediates have been identified including species with iodide in valency states II, IV, VI and VIII. A considerable number of discrepancies exist in the literature data, and requirements for further work are identified. (author)

    2016-10-01

    The most important contributions of radiation chemistry to some selected technological issues related to water-cooled reactors, reprocessing of spent nuclear fuel and high-level radioactive wastes, and fuel evolution during final radioactive waste disposal are highlighted. Chemical reactions occurring at the operating temperatures and pressures of reactors and involving primary transients and stable products from water radiolysis are presented and discussed in terms of the kinetic parameters and radiation chemical yields. The knowledge of these parameters is essential since they serve as input data to the models of water radiolysis in the primary loop of light water reactors and super critical water reactors. Selected features of water radiolysis in heterogeneous systems, such as aqueous nanoparticle suspensions and slurries, ceramic oxides surfaces, nanoporous, and cement-based materials, are discussed. They are of particular concern in the primary cooling loops in nuclear reactors and long-term storage of nuclear waste in geological repositories. This also includes radiation-induced processes related to corrosion of cladding materials and copper-coated iron canisters, dissolution of spent nuclear fuel, and changes of bentonite clays properties. Radiation-induced processes affecting stability of solvents and solvent extraction ligands as well oxidation states of actinide metal ions during recycling of the spent nuclear fuel are also briefly summarized.

    1976-01-01

    Among the Japanese radiological technicians, four deaths from aplastic anemia have been reported after 1930. On the other hand, during the period from 1930 to 1960, the population of radiological technicians is estimated to be 74,400 man-years, in which 0.5 aplastic anemias are expected. However, actually three died from aplastic anemia. This difference is statistically significant at the 1% level. While, in the period from 1961 to 1973, the observed value is 1 against 0.7 expected. It is concluded that aplastic anemia had been induced frequently among the Japanese radiological technicians in the era when there was much exposure to occupational radiation. (orig.) [de

  16. Radiation chemistry of salt-mine brines and hydrates. [Gamma radiation

    Certain aspects of the radiation chemistry of NaCl-saturated MgCl/sub 2/ solutions and MgCl/sub 2/ hydrates at temperatures in the range of 30 to 180/sup 0/C were investigated through experiments. A principal objective was to establish the values for the yields of H/sub 2/ (G(H/sub 2/)) and accompanying oxidants in the gamma-ray radiolysis of concentrated brines that might occur in waste repositories in salt. We concluded that G(H/sub 2/) from gamma-irradiated brine solution into a simultaneously irradiated, deaerated atmosphere above the solution is between 0.48 and 0.49 over most of the range 30 to 143/sup 0/C. The yield is probably somewhat lower at the lower end of this range, averaging 0.44 at 30 to 45/sup 0/C. Changes in the relative amounts of MgCl/sub 2/ and NaCl in the NaCl-saturated solutions have negligible effects on the yield. The yield of O/sub 2/ into the same atmosphere averages 0.13, independent of the temperature and brine composition, showing that only about 50% of the radiolytic oxidant that was formed along with the H/sub 2/ was present as O/sub 2/. We did not identify the species that compose the remainder of the oxidant. We concluded that the yield of H/sub 2/ from a gamma-irradiated brine solution into a simultaneously irradiated atmosphere containing 5 to 8% air in He may be greater than the yield in deaerated systems by amounts ranging from 0% for temperatures of 73 to 85/sup 0/C, to about 30 and 40% for temperatures in the ranges 100 to 143/sup 0/C and 30 to 45/sup 0/C, respectively. We did not establish the mechanism whereby the air affected the yields of H/sub 2/ and O/sub 2/. The values found in this work for G(H/sub 2/) in deaerated systems are in approximate agreement with the value of 0.44 for the gamma-irradiation yield of H/sub 2/ in pure H/sub 2/O at room temperature. They are also in agreement with the values predicted by extrapolation from the findings of previous researchers for the value for G(H/sub 2/) in 2 M NaCl solutions

    Since 1939, it has been known that, silicosis and extrinsic allergic alveolitis can be seen among dental technicians. The interstitial disease caused by the exposure to complex substances used by dental technicians is classified as a special group called dental technician's pneumoconiosis. A 36-year-old man, who has no smoking history, presented with severe dyspnea. He had worked in different dental laboratories for 22 years, but he did not have respiratory symptoms until five years ago. After that date, he had hospitalized and had been examined for respiratory pathologies for many times. He had came to our clinic, because of the progression of his dyspnea. Diffuse pulmonary parenchymal infiltrates which can be related with pneumoconiosis and chronic type 1 respiratory deficiency had been diagnosed as the result of the examinations. While he has no history of smoking or any other risk factors or diseases in his medical history, the case was accepted as dental technician's pneumoconiosis. The factors related with the pathogenesis of dental technician's pneumoconiosis are; the complex compound of the substances (metal dusts, silica, plaster, wax and resins, chemical liquids, methyl methacrylate) used in this sector and their effects on the lung parenchyma. Extrinsic allergic alveolitis related with methyl methacrylate has been reported. The most important factor to acquire an occupational lung disease is a complex occupational exposure. The insufficient workplace airing and the lack of preventive measures added on this exposure, the risks become much more greater.

    Full Text Available The most applicable models in safety management put the human factors, employers’ attitudes and behaviors at the center. This study reports an investigation of job satisfaction among business aviation technicians. A demographic information form and Job Satisfaction Survey (JSS were used to collect data from 44 individuals. Data was analyzed using ANOVA and Student’s t-test. Our results show that there is significant difference in total job satisfaction levels with regard to marital status while other personal factors are not related to the total job satisfaction levels. However several sub dimensions of job satisfaction are affected by the workers’ military or civilian origin, their training background, types of companies they work in or their license category. No difference is found in age and position groups. Secondly, study shows that technicians are the most satisfied from the nature of their work, while they are the least satisfied by operational procedures.

    To evaluate the knowledge and attitudes of pharmacy technicians before and after attending a continuing education program about smoking cessation. A pre/post survey of a single group. Two statewide meetings of the Iowa Pharmacy Association. Pharmacy technicians. One 2-hour continuing education (CE) course about smoking cessation for pharmacy technicians. Changes in scores before and after the CE sessions among three domains (knowledge, efficacy, and outcome) of a validated survey instrument. Fifty-one technicians completed both the presession and postsession questionnaire. For the three survey domains, technicians' knowledge (P = .034), efficacy (P < .001), and outcome (P < .001) showed significant improvement between the presession and postsession surveys (Wilcoxon signed rank test). Pharmacy technicians who attended a CE program on smoking cessation improved their knowledge, attitudes, and self-confidence in helping smokers quit. Additional research should be conducted to test the role of pharmacy technicians in smoking cessation promotion.

    Full Text Available What significant changes are librarians and library technicians experiencing in their roles? A survey put forward across Canada to librarians and library technicians addressing this question was conducted in February 2014. Eight hundred eighty-two responses were obtained from librarians, defined as MLIS graduates, and library technicians, defined as graduates from a two-year library diploma program. Respondents needed to have been employed in the last two years in these roles and students of either an MLIS or LIT program were also welcome to participate. The results suggest that both librarians and library technicians perceive their roles as growing in scope and complexity and that the lines of responsibility are blurring. A majority of respondents indicated that they perceive a change in their roles in the past five years and commented on what the perceived changes were. Librarian and library technician roles may be shifting away from what may be viewed as traditional or clearly defined responsibilities and both librarians and library technicians may be taking on new tasks as well as experiencing task overlap. All library staff will need to be fluid, adaptable, and open to change. Library school curricula and workplace training need to incorporate the development of these competencies. Quels sont les changements importants éprouvés par les bibliothécaires et les bibliotechniciens dans leurs rôles? Un sondage mené en février de 2014 a posé cette question aux bibliothécaires et aux bibliotechniciens dans tout le Canada. On a reçu huit-cent quatre-vingt-deux réponses des bibliothécaires, définis comme étant diplômés en MSIB, et les bibliotechniciens, définis comme étant diplômés d’un programme de deux ans en bibliotechnique. Les sondés devaient avoir travaillé au cours des deux dernières années dans ces fonctions et les étudiants d’un programme MSIB ou de bibliothéconomie/ sciences de l’information pouvaient aussi y

    Singh, S.P.; Kesavan, P.C.

    1990-01-01

    Influence of varying concentration of catalase and H 2 O 2 administered individually and in combination treatment during post-hydration on the oxygen-dependent and -independent pathways of damage was assessed in dry barley seeds irradiated in vacuo with 350 Gy of 60 Co gammarays. Both catalase (100 to 500 units/ml) and H 2 O 2 (0.001 to 0.1 mM) afforded significant radioprotection against the post-irradiation O 2 -dependent damage. However, a combination treatment (300 units/ml of catalase and 0.01 mM of H 2 O 2 ) afforded significantl y more protection than either of the additives individually. None of the concentrations of catalase exerted any effect on the O 2 -independent pathway, whereas H 2 O 2 at higher concentrations (1 and 10 mM) significantly potentiated both the O 2 -dependent as well as the -independent components of radiation damage. These observations are better explicable in terms of radiation chemistry. (author). 16 refs., 3 tabs

    Several computer codes simulating chemical reactions in particles systems are based on the Green's functions of the diffusion equation (GFDE). Indeed, many types of chemical systems have been simulated using the exact GFDE, which has also become the gold standard for validating other theoretical models. In this work, a simulation algorithm is presented to sample the interparticle distance for partially diffusion-controlled reversible ABCD reaction. This algorithm is considered exact for 2-particles systems, is faster than conventional look-up tables and uses only a few kilobytes of memory. The simulation results obtained with this method are compared with those obtained with the independent reaction times (IRT) method. This work is part of our effort in developing models to understand the role of chemical reactions in the radiation effects on cells and tissues and may eventually be included in event-based models of space radiation risks. However, as many reactions are of this type in biological systems, this algorithm might play a pivotal role in future simulation programs not only in radiation chemistry, but also in the simulation of biochemical networks in time and space as well.

    1981-01-01

    An important source of information on the question of whether or not toxic or other deleterious substances are formed in the radiation sterilization of foods is the chemical study of reaction products and reaction mechanisms in the radiolysis of individual food components. The present evaluation of the radiation chemistry of amino acids, peptides and proteins outlines the various radiation-induced processes which lead to amino acid degradation and to the synthesis of amino acid derivatives of higher molecular weight. Among the latter are the α,α'-diamino dicarboxylic acids which are formed as major products in the radiolysis of peptides both in aqueous solution and in the solid state. The α,α'-diamino acids are of particular interest as irradiation products because they represent a class of compounds not normally encountered in plant and animal protein sources. Such compounds have, however, been isolated from certain types of bacteria and bacterial products. All of the available data strongly suggest that the α,α'-diamino acids are produced in significant yield in the radiation sterilization of high protein foods. The importance of initiating extensive chemical and biological studies of these and of other high molecular weight products in irradiated food is emphasised. (author)

While the prevalence of burnout in practicing emergency medicine (EM) professionals has been studied, little is known of the prevalence and factors across physicians, nurses, technicians, and health information technicians working for the same institution. The aim of this study was to assess burnout differences across EM professional types.The total population of 250 EM professionals at 2 public urban hospitals in Turkey were surveyed using the Maslach Burnout Inventory and basic social- and work-related demographics. Descriptive statistics, ANOVA, and additional post hoc tests were computed.Findings show that EE and DP scores were high across all occupational groups, while scores on PA were low. There was a statistically significant difference between nurses and medical technicians (P nurses and medical technicians (P Burnout can be high across occupational groups in the emergency department. Burnout is important for EM administrators to assess across human resources. Statistically significant differences across socio-demographic groups vary across occupational groups. However, differences between occupational groups may not be explained effectively by the demographic factors assessed in this or other prior studies. Rather, the factors associated with burnout are incomplete and require further institutional, cultural, and organizational analyses including differentiating between job tasks carried out by each EM job type.

    The Westinghouse Hanford Company (WHC) has developed and is implementing a continuing training program for RCTs. This program was designed to meet the requirements of the DOE and Hanford Site Radiological Control Manual. The program is scheduled on a biennial (two year), six cycle format, where each cycle is seventeen weeks in length. This enables the technician to be in the classroom three times per year, for an average of four days each cycle. Content emphasis is placed on: academics review; lessons learned; new equipment and procedures; practical skills training; and oral board preparation. Academic reviews provide refresher training on core and site academics in both lecture and overview formats. During the first five cycles, an average of six lessons are presented. A preparatory exam is administered along with a quiz covering previous cycles. The sixth cycle is dedicated to an academic review of all previous lesson content, the final comprehensive exam, and the oral examination boards. In conjunction with continuing training, technicians receive additional company required training, providing a substantial cost savings to WHC. WHC employs approximately 300 RCTs

    A long held principle is that for every engineer and scientist there is a need for ten technicians to maximize the efficiency of the technology team for meeting needs of industry and government. Developing an adequate supply of technicians to meet the requirements of the materials related industry will be a challenge and difficult to accomplish. A variety of agencies feel the need and wish to support development of engineering materials technology programs. In a joint effort among Battelle Laboratories, the Department of Energy (DOE) and Northwest College and University Association for Science (NORCUS), the development of an engineering materials technology program for vocational programs and community colleges for the Pacific Northwest Region was recently completed. This effort has implications for a national model. The model Associate of Applied Science degree in Engineering Materials Technology shown provides a general structure. It purposely has course titles which need delimiting while also including a core of courses necessary to develop cognitive, affective and psychomotor skills with the underlining principles of math, science and technology so students have job entry skills, and so that students can learn about and adapt to evolving technology.

    Parrott, J.R.; Nicol, R.G.

    The training of personnel to carry out radiochemical operations at ORNL is a formidable and recurrent task since programs are constantly shifting. It is essential that provisions be made for the routine retraining of these personnel if they are to make effective contributions on a continuing basis. Training methods are described that have emerged as a result of thirty years experience in a variety of radiochemical pilot-plant programs. Emphasis is placed on training programs for technicians for the 233 U Processing Facility since essentially all aspects of radiochemical operations are encountered in this facility. These programs have included operations performed in glove boxes, hot-cell manipulator work handling high-neutron-emitting isotopes, and the entire spectrum of remote solvent extraction operations.

    Full Text Available Objectives: To explore the rate of pneumoconiosis in dental technicians (DTP and to evaluate the risk factors. Material and Methods: Data of 893 dental technicians, who were admitted to our hospital in the period January 2007–May 2012, from 170 dental laboratories were retrospectively examined. Demographic data, respiratory symptoms, smoking status, work duration, working fields, exposure to sandblasting, physical examination findings, chest radiographs, pulmonary function tests and high-resolution computed tomography results were evaluated. Results: Dental technicians’ pneumoconiosis rate was 10.1% among 893 cases. The disease was more common among males and in those exposed to sandblasting who had 77-fold higher risk of DTP. The highest profusion subcategory was 3/+ (according to the International Labour Organization (ILO 2011 standards and the large opacity rate was 13.3%. Conclusions: To the best of our knowledge, it was the largest DTP case series (N = 893/90 in the literature in English. Health screenings should be performed regularly for the early diagnosis of pneumoconiosis, which is an important occupational disease for dental technicians.

This study surveyed EMT instructors and medical directors to identify the most desirable core competencies for all levels of EMTs in Taiwan. Methods: A principal components analysis with Varimax rotation was conducted. An online questionnaire was distributed to obtain perspectives of EMT instructors and medical directors on the most desirable core competencies for EMTs. The target population was EMT training-course instructors and medical directors of fire departments in Taiwan. The questionnaire comprised 61 competency items, and multiple-choice and open-ended questions were used to obtain respondents’ perspectives of the Taiwanese EMT training and education system. Results: The results identified three factors at EMT-1 and EMT-2 levels and five factors at the EMT-Paramedic level. The factors for EMT-1 and EMT-2 were similar, and those for EMT-Paramedics identified further comprehensive competence perspectives. The key factors that appear to influence the development of the Taiwanese Emergency Medical Services (EMS education system are the attitude of authorities, the licensure system, and legislation. Conclusion: The findings present new core competencies for the Taiwanese EMT system and provide capacity to redesign curricula and reconsider roles for EMT-1 and EMT-2 technicians. At the EMT-Paramedic level, the findings demonstrate the importance of

    To describe and apply a model for combining self-assessed frequency and criticality for pharmacy technicians' roles and to evaluate similarities and differences between attitudes toward public safety in various practice settings. Cross-sectional mail survey of randomly selected pharmacy technicians in one state. Iowa in fall 2012. 1,000 registered technicians. Mail survey with option for online completion. Scored ratings related to perceptions of frequency and criticality of roles. Technicians rated role frequency on a scale from 1 (not responsible) to 6 (daily) and role criticality on a scale from 1 (no importance) to 4 (extremely important). A weighted relative importance score was ranked to show importance of the role considering frequency and criticality together. The response rate was 25.81%. Ratings for frequency were correlated to ratings for criticality for 22 of 23 roles. A Mann-Whitney U test found a difference between ambulatory technicians and hospital technicians. A visual matrix of a dual-scaled analysis showed both groups' role ratings to be positively linearly related. Hospital technicians showed wider discrimination in their ratings for some roles than for others. Perceived role frequency and criticality can be considered together to contextualize the practice environment. The data suggest a relationship between perceived frequency of role performed and perception of a role's criticality. The study found differences between how technicians from various practice settings perceive their roles.

    Chitosan as a raw material with special properties has drawn attention of scientists working in the field of radiation processing and natural polymer products development, and also of specialists working in the field of radiation protection and oncologists. Especially the applications concern reduced molecular weight chitosan which still retain its chemical structure; such form of the compound is fostering biological, physical and chemical reactivity of the product. Chitosan degrades into fragments under gamma-ray or electron beam irradiation. Antibacterial properties of the product are applied in manufacturing hydrogel for wound dressing and additional healing properties can be achieved by incorporating in the hydrogel matrix chitosan bonded silver clusters. Another possible application of chitosan is in reducing radiation damage to the radiation workers or radiation cured patients. In the case of radioisotopes oral or respiratory chitosan-based materials can be applied as chelators. Applications of chitosan in oncology are also reported.

    Leadership plays a crucial role in many professions, especially in challenging positions such as emergency medical service jobs. The purpose of this study was to explore the relationship between managers' leadership styles and emergency medical technicians' job satisfaction. This is a descriptive and cross-sectional study that was carried out in 2010. The research population included 21 managers and 87 emergency medical technicians working in 23 stations in Isfahan city, Iran. The main tools used for data accumulation were the Multiple Leadership Questionnaire for evaluating leadership styles and the Job Descriptive Index for measuring job satisfaction levels. Also, the Pearson correlation analysis test was used to evaluate the relationship between leadership style and job satisfaction. Among both managers and technicians, the highest mean score related to the transformational management style, whereas the lowest mean score related to the laissez-faire management style. Moreover, a significant relationship (Pjob satisfaction. However, no significant relationship was observed between the laissez-faire management style and job satisfaction. Considering the importance of job satisfaction in medical emergencies, it is recommended that health sector policy makers should provide the groundwork for implementing the transformational leadership style to enhance job satisfaction of the medical emergency staff.

    The process used in preparing this administrative report provided the means of documenting departmental support of technician task expansion, cost benefits, increased availability of professional time, and the need for a dynamic department. Some of the benefits to St. Luke's Regional Medical Center and its Pharmacy Department were an increase in technician job satisfaction, improved quality of patient care attributable to the increased scope of pharmacy service, and up to 8554 hours per year of professional time available for more clinically oriented responsibilities. If technician turnover were decreased by half, technician pricing errors eliminated, and technicians assumed the identified technical tasks, potential monetary benefits could be as much as +116,900 per year. The departmental cost of implementing these recommendations would be an additional 4.16 technician FTEs, and the professional time for training, supervising, and coordinating technicians and functions. These recommendations were well received by pharmacy administration, and the committee was asked to develop a list of priorities and an implementation plan for administrative approval.

    In recent years, the costs of epinephrine autoinjectors (EAIs) in the United States have risen substantially. King County Emergency Medical Services implemented the "Check and Inject" program to replace EAIs by teaching emergency medical technicians (EMTs) to manually aspirate epinephrine from a single-use 1 mg/mL epinephrine vial using a needle and syringe followed by prehospital intramuscular administration of the correct adult or pediatric dose of epinephrine for anaphylaxis or serious allergic reaction. Treatment was guided by an EMT protocol that required a trigger and symptoms. We sought to determine if the "Check and Inject" program was safely implemented by EMTs treating presumed prehospital anaphylaxis or serious allergic reaction. We conducted a prospective investigation of all cases treated as part of the "Check and Inject" program from July 2014 through December 2016 in suburban King County, Washington, and January 2016 through December 2016 within the city of Seattle. All cases were prospectively collected using a custom quality improvement data form completed by the first responding EMTs. Two physicians completed a structured review of each EMS medical record to determine if the EMTs followed the Check and Inject protocol and determine if epinephrine was clinically-indicated based on physician review. Of the 411 cases eligible for analysis, EMTs followed the protocol appropriately in 367 (89.3%) cases. In the remaining 44 (10.7%) cases, the EMS incident report form failed to document either a clear inciting allergic trigger or an appropriate symptom from the protocol list. Physician review determined that epinephrine was clinically indicated in 36 of the 44 cases. Among the remaining 8 cases (1.9%) that did not meet protocol criteria and were not clinically-indicated based on physician review, none had a documented adverse reaction to the epinephrine. We observed that EMTs successfully implemented the manual "Check and Inject" program for severe

    The Arizona Nuclear Power Project (ANPP), a three-reactor site located 50 miles west of Phoenix, Arizona, has developed and implemented a program for evaluating individual chemistry technician analytical performance on a routine basis. About 45 chemistry technicians are employed at the site, 15 at each operating unit. The technicians routinely perform trace level analyses for impurities of concern to PWRs. Each month a set of blind samples is provided by an outside vendor. The blind samples contain 16 parameters which are matrixed to approximate the PWR's primary and secondary cycles. Nine technicians receive the samples, three from each operating unit, and perform the required analyses. Acceptance criteria for successful performance on the blind parameters is based on the values found in the Institute of Nuclear Power Operations (INPO) Document 83-016, Revision 2, August 1989, Chemistry Quality Control Program. The goal of the program is to have each technician demonstrate acceptable performance on each of 16 analytical parameters. On completion of each monthly set, a summary report of all of the analytical results for the sample set is prepared. From the summary report, analytical bias can be detected, technician performance is documented, and overall laboratory performance can be evaluated. The program has been very successful at satisfying the INPO requirement that the analytical performance of each individual technician should be checked on at least a six-month frequency for all important parameters measured. This paper describes the program as implemented at the Palo Verde Nuclear Generating Station and provides a summary report and trend and bias graphs for illustrative purposes

    Full Text Available Intestinal parasitic infections caused by Giardia lamblia (GL, Ascaris lumbriocoides (AL and Entamoeba histolytica/dispar (Eh/Ed are highly prevalent among indigenous groups in Mexico. In resource-constrained settings, direct microscopic fecal examination continues to be a common diagnostic method in spite its limited accuracy. This study aimed at illustrating the effect of training local laboratory technicians from a rural reference hospital located in a marginalized indigenous region of northern Mexico to assess the inter-observer reliability of GL, AL, and Eh/Ed diagnoses. Two experienced technicians working at the hospital were trained and standardized for two full weeks in the Parasitology Laboratory at the National Children’s Hospital from Mexico City. Diagnoses were made by microscopy of two serial stool samples processed using the modified Faust zinc sulphate centrifugal flotation technique to concentrate AL eggs and GL and Eh/Ed cysts. Observations were done independently, and the final diagnosis for each observer was established when at least one of the two samples resulted positive. Reliability analyses from serial stool samples were conducted using Cohen’s kappa correlation coefficient (ĸ for each parasite. Agreement between observers reached 88.7, 72.4, and 80.5% for Eh/Ed, AL, and GL, respectively. Largest kappa coefficient was observed for GL (ĸ=0.55, followed by Eh/Ed (ĸ=0.30, and AL (ĸ=0.08. Prevalence of Eh/Ed, AL and GL according to observers 1 and 2 were 3.4 vs. 13.5%, 4.0 vs. 28.2%, and 32.2 vs. 33.3%, respectively. Except for GL, reliability was very low leading to major differences in prevalence estimates. These results question the value of training technicians, as intestinal parasitic microscopic diagnoses seemed to be very difficult to replicate between observers questioning their validity, leading to differences in clinical decisions, and in prevalence estimates.

    Absolute values of quantum yield Φ(hν) of singlet exciton formation in anthracene single crystals were measured as a function of photon energy hν, with the usage of synchrotron radiation (SR) in 3-700 eV region. Values of Φ(hν) were found to increase linearly for hν≥75 eV. For hν≤40 eV, values of Φ(hν) gave a wealth of structures and are not linear to hν. Because number of secondary electrons produced by radiation is thought to increase in proportional to the incident photon energy, it is natural to conclude that the radiation chemistry effect becomes dominant above 75 eV. On the other hand, values of Φ(hν) showed response due to resonance rather than linear dependence with hν, which implies that the photochemical effect is dominant below 40 eV

    2014-02-01

    The American Society of Health- System Pharmacists (ASHP) believes that specially trained pharmacy technicians can assume important supportive roles in pharmacy informatics. These roles include automation and technology systems management, management of projects, training and education, policy and governance, customer service, charge integrity, and reporting. Such roles require pharmacy technicians to gain expertise in information technology (IT) systems, including knowledge of interfaces, computer management techniques, problem resolution, and database maintenance. This knowledge could be acquired through specialized training or experience in a health science or allied scientific field (e.g., health informatics). With appropriate safeguards and supervision, pharmacy technician informaticists (PTIs) will manage IT processes in health-system pharmacy services, ensuring a safe and efficient medication-use process.

    Asbestos was used in dentistry as a binder in periodontal dressings and as lining material for casting rings and crucible. However, until now, only one case of malignant mesothelioma with occupational exposure to asbestos in dental practice has been reported. We present 4 pleural mesotheliomas out of 5344 cases identified in Lombardy, Italy, in 2000-2014. Three men had been working as dental laboratory technicians, with asbestos exposure for 10, 34, and 4 years, and one woman had been helping her husband for 30 years in manufacturing dental prostheses. The men described the use of asbestos as a lining material for casting rings, while the woman was not able to confirm this use. We confirm the association of malignant mesothelioma with dental technician work. Dental technicians suffering from mesothelioma should be questioned about past occupational asbestos exposure. © 2017 Wiley Periodicals, Inc.

    1976-01-01

    Among Japanese radiological technicians, four deaths from aplastic anemia have been recorded. Based on this fact, some epidemiological considerations are tried. During the period from 1930 to 1960, the population of radiological technicians is estimated to be 74,400 man-years, in which 0.5 aplastic anemias are expected. However actually three died from aplastic anemia. This difference is statistically significant at the 1% level. On the other hand, in the period from 1961 to 1973, the observed value is 1 against 0.7 expected. It is concluded that aplastic anemia had been frequently induced among Japanese radiological technicians in the era when there was much exposure to occupational radiation. (auth.)

    2006-01-01

    Selectivity of the primary chemical events induced by ionizing radiation in molecular systems is the key issue of basic radiation chemistry, which is crucially important for controlling the radiation sensitivity of various-type organic and polymeric materials and designing new effective approaches to the radiation modification. In the past decade we have demonstrated that many features of selective localization of the radiation-induced effects in molecular solids can be understood on the basis of model studies of the primary ionized molecules in rigid low-temperature matrices. This talk will outline the key results of these studies and possible implications for radiation chemistry of vatious systems. In particular, the following aspects will be considered: (1) Spectroscopic characteristics of ustable ionized molecules in low-temperature matrices and their correlations with the site-selective reactivity. (2) Experimental modeling of the effect of excess energy on the properties of primary ionized molecules in condensed phases. (3) Intramolecular long-range effects with particular impact on the properties of ionized bifunctional molecules of X-(CH 2 ) n -X and X-(CH 2 ) n -Y types. (4) Modeling of intermolecular long-range positive hole transfer between molecular traps with close ionization energy and manifestations of 'fine tuning' effects resulting from conformation variations and intermolecular interactions. Several illustrative examples of correlation between the properties of primary ionized molecules and selectivity of the radiation-chemical transformations in organic solids and macromolecules will be presented. Finally, the problem of prediction of the radiation-chemical behaviour of complex organic systems on the basis of limited spectroscopic information and quantum-chemical data obtained for model systems will be addressed.

    Over the last two decades, a significant trend in health and safety has been toward greater specialization. However, compartmentalization of health and safety disciplines often leads to an inequity in resources, especially when appropriations overemphasize one risk to the detriment of others. For example, overemphasis on radiological safety can create an imbalance in overall worker protection. A multidisciplinary technical can help restore the balance and provide for a healthier and safer work environment. The key advantages of a multidisciplinary health and safety technician include: Broad coverage of the work area by one technician, More diverse use of the technician pool, Better coverage for off-shift or nonstandard hours, Balance of risks because all hazards are considered, Integrated emergency response, Ownership, Less time of identify the correct person with the requisite skills. We have developed a new standard that establishes the training and related qualifications for a multidisciplinary health and safety technician. The areas of training and qualification that are addressed include elements of industrial hygiene, industrial safety, fire protection, electrical safety, construction safety, and radiation safety. The initial core training program ensures that individuals are trained to the performance of requirements of the job. Initial training is in five areas: Fundamentals, Hazard recognition, Hazard assessment, Hazards controls, Hazards minimization. Core training is followed by formal qualification on specific tasks, including ventilation surveys, air monitoring, noise assessments, radiological monitoring, area inspections, work-area setups, and work coverage. The new standard addresses not only training topics and requirements, but also guidance to ensure that performance objectives are met. The standard applies to technicians, supervisors, technologists, and six specialty areas, including academic institutions and decontamination and decommissioning

    2012-07-12

    The overall goal of this project has been to develop curricula, certification requirements, and accreditation standards for training on energy efficient practices and technologies for commercial building technicians. These training products will advance industry expertise towards net-zero energy commercial building goals and will result in a substantial reduction in energy use. The ultimate objective is to develop a workforce that can bring existing commercial buildings up to their energy performance potential and ensure that new commercial buildings do not fall below their expected optimal level of performance. Commercial building equipment technicians participating in this training program will learn how to best operate commercial buildings to ensure they reach their expected energy performance level. The training is a combination of classroom, online and on-site lessons. The Texas Engineering Extension Service (TEEX) developed curricula using subject matter and adult learning experts to ensure the training meets certification requirements and accreditation standards for training these technicians. The training targets a specific climate zone to meets the needs, specialized expertise, and perspectives of the commercial building equipment technicians in that zone. The combination of efficient operations and advanced design will improve the internal built environment of a commercial building by increasing comfort and safety, while reducing energy use and environmental impact. Properly trained technicians will ensure equipment operates at design specifications. A second impact is a more highly trained workforce that is better equipped to obtain employment. Organizations that contributed to the development of the training program include TEEX and the Texas Engineering Experiment Station (TEES) (both members of The Texas A&M University System). TEES is also a member of the Building Commissioning Association. This report includes a description of the project

    An available and economical supply to future manpower requirements for various types of nuclear technicians can be met by developing and/or restructuring two-year, post-secondary programs at local educational institutions. The Technical Education Research Centers program is under contract from the U.S. Office of Education to delineate the job requirements and develop curricula and instructional materials for two-year, post-secondary training of nuclear technicians. Six job categories have been identified along with corresponding tasks which the technician performs. These categories are: Reactor Operator, Nuclear Instrumentation Technician, Nuclear QA/QC Technician, Radiochemistry Technician, Radiation Protection Technician and Nuclear Medicine Technician. For the first five categories curricula have been established, courses have been described, and instructional materials are being written

    1978-05-01

    Residential institutions have historically had problems attracting and retaining reliable unskilled personnel to fill technician-level positions. Even though there is little empirical evidence to support a relationship between staff stability and resident habilitation, there assuredly are such effects. A first step toward assessing these effects, and toward controlling costly technician withdrawal behavior (specifically, turnover and absenteeism), is the use of a common set of measures. The precipitants of employee withdrawal may be categorized into three areas that are subject to empirical investigation and intervention: extra-institutional factors, intra-institutional management, and factors surrounding the individual worker. Predictive research, for selection purposes, has not yielded much information that would be of use to administrators. Traditional and more recent explanations were reviewed and some direction suggested for further research.

    Communication between the clinician and the technician has been an ongoing problem in dentistry. To improve the issue, a dental software application has been developed--the Virtual Facebow App. It is an alternative to the traditional analog facebow, used to orient the maxillary cast in mounting. Comparison data of the two methods indicated that the digitized virtual facebow provided increased efficiency in mounting, increased accuracy in occlusion, and lower cost. Occlusal accuracy, lab time, and total time were statistically significant (Pcommunication.

    2017-07-01

    The results of the 2015 National Certified Pharmacy Technician Workforce Survey are described. A survey was e-mailed to a randomized sample of 5,000 certified pharmacy technicians (CPhTs) throughout the United States, with response reminders employed. Survey items eliciting demographic and work characteristics and work life attitudes were generated from the literature and qualitative interviews. This study aimed to describe job satisfaction, sources of stress, profession and employer commitment, education and training, and reasons for entry into the profession among CPhTs and determine relationships between those variables and CPhTs' level of involvement in various work activities, with particular attention paid to differences in practice setting. Frequency statistics, correlation analysis, and means testing were used to meet study objectives and identify significant differences. A total of 516 CPhTs currently working as a pharmacy technician responded to the survey. The CPhTs reported high levels of involvement in more traditional activities but less involvement in those that involve greater cognitive load. Respondents reported moderate levels of job satisfaction and commitment and somewhat high levels of stress overall. Most CPhTs chose to be a pharmacy technician because they desired to enter a healthcare field and help people and were recruited. CPhTs derived benefit from all aspects of education and training evaluated and most from on-the-job training. Perceived value of education and training was associated with higher satisfaction and commitment and with lower stress. There were a number of differences in these work life attitudes across practice settings and by involvement in various job functions. The results of the survey indicated that job satisfaction and commitment were moderate and that stress levels were somewhat high among CPhTs. There were a number of differences in work life attitudes across practice settings and by involvement in various job

    1997-01-01

    To determine the reasons for attrition in a clinical laboratory technician-associate degree program, a retrospective study was done on classes entering from 1987 to 1992. Suggestions are made to increase retention. The medical laboratory department at the Community College of Philadelphia in Pennsylvania. There were 43,987 students enrolled for the 1993 to 1994 academic year; 17,846 full time equivalents at the college. Clinical laboratory technician students averaged 26.2 years and were 26% male and 74% female, which closely paralleled the college. The ethnic make-up of the clinical laboratory technician classes was 54% White, 32% African American, 11% Asian, and 3% Latin American, compared to 48% African American, 36% White, 10% Asian, and 6% Latin American students in the college. A retrospective study was performed to evaluate attrition rates for the classes entering the clinical laboratory technician program at the Community College of Philadelphia from 1987 to 1992. Reasons for this attrition were tabulated and evaluated. One hundred twenty-nine students entered the program and 75 graduated, producing an attrition rate of 42%. There were 6 categories of reasons given for not completing the program: academic difficulties, dislike of the laboratory science field, family problems, financial problems, substance abuse, and other problems not specified. Because 80% of the attrition was due to poor academic performance and a dislike of the field, several changes are being made in the Community College of Philadelphia's retention program. An enhanced orientation will be given to all students, and students will be required to visit a hospital laboratory. Early faculty intervention and peer counseling for students with poor academic performance will be instituted.

  4. Training needs analysis for engineering technicians in Oman

    Science.gov (United States)

    Al-Mughairi, Abdulkarim Sultan

    This thesis examines the transition from the Omani Colleges of Technology (CT) to employment of its engineering graduates. It arises out of concerns that the transition to the labour market for engineering graduate is problematical. The research was carried out to identify the knowledge, skills, and abilities (KSA) of engineering technicians required in the Omani market place. The aim is to provide local curriculum designers in the Colleges of Technology with sufficient information about the required KSA in order to create and enhance the engineering curriculum so that it has greater capacity to meet the needs of a variety of stakeholders and of employers in particular. This in turn has the potential to bridge the gap between what is presently taught and what the workplace demands. Personnel psychologists identify views concerning the skills that are required for different jobs. One of these is based on the assumption that quite different skills are required in different jobs (SCANS, 1990). This view generates approaches within job analysis: the worker-oriented and the task-oriented approaches. This research uses Position Analysis Questionnaire (PAQ), which is a worker-oriented job analysis instrument, to investigate the KSA required to perform some of the engineering technician jobs in Omani industries. In addition, semi-structured interviews were used to investigate the factors that either hinder or entirely prevent the new graduates from Colleges of Technology from being accepted in the workforce pool. The major research findings concern the dimensions of knowledge, skills, and abilities of six engineering technician job titles and the major factors that hinder or (prevent) the technical college graduates from being accepted in the market place in Oman. These findings would definitely help design better transition route and bridge the gap between the CT technicians engineering programmes and the workplace demands.

    2017-09-01

    The increasing role of chemistry in industrial production and its direct and indirect impacts in everyday life create the need for continuous search and efficiency improvement of new methods for decomposition/removal of different classes of waterborne anthropogenic pollutants. This review paper addresses a highly promising class of water treatment solutions, aimed at tackling the pressing problem of emerging contaminants in natural and drinking waters and wastewater discharges. Radiation processing, a technology originating from radiation chemistry studies, has shown encouraging results in the treatment of (mainly) organic water pollution. Radiation ("high energy") processing is an additive-free technology using short-lived reactive species formed by the radiolysis of water, both oxidative and reducing, to carry out decomposition of organic pollutants. The paper illustrates the basic principles of radiolytic treatment of organic pollutants in water and wastewaters and specifically of one of its most practical implementations (electron beam processing). Application examples, highlighting the technology's strong points and operational conditions are described, and a discussion on the possible future of this technology follows.

  7. Exploring the limitations of the Hantzsch method used for quantification of hydroxyl radicals in systems of relevance for interfacial radiation chemistry

    2017-01-01

    In the presence of Tris or methanol, hydroxyl radicals in systems of relevance for interfacial radiation chemistry can be quantified indirectly via the Hantzsch method by determining the amount of the scavenging product formaldehyde formed. In this work, the influence of the presence of H2O2 on the Hantzsch method using acetoacetanilide (AAA) as derivatization reagent is studied. The experiments show that the measured CH2O concentration deviates from the actual concentration in the presence of H2O2 and the deviation increases with increasing [H2O2]0/[CH2O]0. The deviation is negative, i.e., the measured formaldehyde concentration is lower than the actual concentration. This leads to an underestimation of the hydroxyl radical production in systems containing significant amount of H2O2. The main reason for the deviation is found to be three coupled equilibria involving H2O2, CH2O and the derivative produced in the Hantzsch method.

  8. RITRACKS: A Software for Simulation of Stochastic Radiation Track Structure, Micro and Nanodosimetry, Radiation Chemistry and DNA Damage for Heavy Ions

    Plante, I; Wu, H

    2014-01-01

    The code RITRACKS (Relativistic Ion Tracks) has been developed over the last few years at the NASA Johnson Space Center to simulate the effects of ionizing radiations at the microscopic scale, to understand the effects of space radiation at the biological level. The fundamental part of this code is the stochastic simulation of radiation track structure of heavy ions, an important component of space radiations. The code can calculate many relevant quantities such as the radial dose, voxel dose, and may also be used to calculate the dose in spherical and cylindrical targets of various sizes. Recently, we have incorporated DNA structure and damage simulations at the molecular scale in RITRACKS. The direct effect of radiations is simulated by introducing a slight modification of the existing particle transport algorithms, using the Binary-Encounter-Bethe model of ionization cross sections for each molecular orbitals of DNA. The simulation of radiation chemistry is done by a step-by-step diffusion-reaction program based on the Green's functions of the diffusion equation]. This approach is also used to simulate the indirect effect of ionizing radiation on DNA. The software can be installed independently on PC and tablets using the Windows operating system and does not require any coding from the user. It includes a Graphic User Interface (GUI) and a 3D OpenGL visualization interface. The calculations are executed simultaneously (in parallel) on multiple CPUs. The main features of the software will be presented.

    To determine the influence of age, year of graduation, and video game experience on baseline laparoscopic psychomotor skills. Cross-sectional. Licensed veterinarians (n = 38) and registered veterinary technicians (VTs) (n = 49). A laparoscopic box trainer was set up at the 2016 Ontario Veterinary Medical Association (OVMA) and the 2016 Ontario Association of Veterinary Technicians (OAVT) conferences held in Toronto, Ontario, Canada. Participants volunteered to perform a single repetition of a peg transfer (PT) exercise. Participants were given a short demonstration of the PT task prior to testing. A Spearman's rank correlation (r s ) was used to identify associations between baseline psychomotor skills and self-reported surgical and non-surgical experiences collected via survey. Mann-Whitney U tests were used to compare PT scores in veterinarians and VTs. A P-value of  .05). Veterinary technicians that frequently used chopsticks scored higher than those without chopstick experience (P = .04). Age and year of graduation correlated inversely, while self-reported VG experience correlated positively with laparoscopic psychomotor skills of veterinarians, when assessed on a simulator. The use of chopsticks may contribute to the acquisition of psychomotor skills in VTs. © 2017 The American College of Veterinary Surgeons.

    Full Text Available The aim of the current investigation is to analyze the dental-technicians’ awareness of the soft relining materials, their characteristics, advantages, shortcomings and methods for relining. Materials and methods: For the purpose of this investigation a standard questionnaire has been presented. A direct survey method, documentary and statistical method, as well as graphical methods, including tables, charts, graphics and figures, were used. Data were analysed with the help of IBM SPSS Statistics (ver. 19. Results: One hundred and eight dental technicians were included in the survey, evenly distributed by gender. Removable and fixed prosthodontics is the most commonly mentioned spheres of dental activities. Almost all included in the investigation point out the laboratory relining method as the most frequently used. Acrylic and silicone SRM are the most used groups of relining materials. Change of colour and hardness are the most frequently noticed shortcomings of these materials. The majority of the dental technicians declare that they have never done replacement of SRM or the relining has lasted more than a year. Discussion: The correlation between the age and the years of labour service among the participants is quite obvious. Most of them start working soon after their graduation. Removable prosthodontics is among the priorities for the majority of the labs. Conclusion: Although their unambiguous advantages, the soft relining materials have lots of shortcomings as well. The major problems are connected with their change of colour and hardness. Nevertheless, the dental technicians find them useful and reliable in overcoming specific prosthetic problems.

    The efficacy of radiation therapy is to eradicate the tumor while preserving the integrity of normal tissues. Technological advances have allowed to develop techniques capable of modulating doses delivered to the target volume, providing more effective treatments. However, the operational complexity of these techniques makes the benefits offered are directly proportional to the chances of occurrences of serious errors. The objective of this work is to analyze the steps performed by the technician/technologist in Intensity Modulated Radiotherapy (IMRT), to detect possible errors in order to determine ways to mitigate them. After literature regarding errors in the radiation therapy, a prospective analysis was performed in the first half of 2012 in a radiation clinic located in the city of Rio de Janeiro, in which 11 technicians/technologists contributed to the survey data analysis. The method of risk analysis Failure Mode and Effects Analysis was used for prospective analysis of accidents/incidents, with respect to a qualitative assessment . The method allowed mapping 16 steps performed by technicians/technologists in the treatments with IMRT, identifying possible failures and their causes allowing to find ways to avoid possible errors. This analysis helped to confirm that the qualification and continuing education of technicians/technologists, allied to implement quality assurance programs and a computerized management can make a tool capable of IMRT to achieve the greatest challenge of radiotherapy.

    It is not fully understood where and how people are exposed to sensitizing metals. Much can be learnt from studying occupational settings where metals are handled. To quantify cobalt (Co), chromium (Cr) and nickel (Ni) exposure on the skin and in the air, and urine levels, in dental technicians working with tools and alloys that may result in skin and respiratory exposure. The metal skin dose was quantified with acid wipe sampling in dental technicians (n = 13). Air exposure was monitored by personal air sampling. Spot urine samples were collected for 24 h. Metals were analysed with inductively coupled plasma mass spectrometry. Before work, Co was detected on the skin of 10 participants (0.00025-0.0039 µg/cm 2 ), and Cr (0.00051-0.011 µg/cm 2 ) and Ni (0.0062-0.15 µg/cm 2 ) on the skin of all participants. After a 2-h period without hand washing, CoCr-exposed participants had more Co on the skin (p = 0.004) than non-CoCr-exposed participants. Co was found in 10 air samples (0.22-155 µg/m 3 ), Cr in nine (0.43-71 µg/m 3 ), and Ni in four (0.48-3.7 µg/m 3 ). Metal urine concentrations were considered to be normal. Dental technicians were exposed to Co, Cr and Ni on the skin and through the air, which was not reflected in the urine concentrations in this study. Cobalt skin doses may potentially elicit allergic contact dermatitis and cause sensitization. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    2004-01-01

    In the modern optical shop, technicians are typically skilled machine operators who work on only one phase of the manufacture for each and every component. The product is designed, specified, methodized, scheduled and integrated by people off the shop floor. Even at the component level, the people inside the shop usually see only one stage of completion. In an effort to make the relevance of their work visible; to demonstrate competence to their peers; to gain appreciation for the work of others; and to give them a meaningful connection with the functions of optical systems, I created "The Telescope Project" for my former employer. I invited those interested to participate in an after-hours, partially subsidized project to build telescopes for themselves. The ground-rules included that we would all make the same design (thus practicing consensus and configuration management); that we would all work on every phase (thus learning from each other); and that we would obtain our parts by random lot at the end (thus making quality assurance a personal issue). In the process the participating technicians learned about optical theory, design, tolerancing, negotiation, scheduling, purchasing, fabrication, coating and assembly. They developed an appreciation for each other's contributions and a broader perspective on the consequences of their actions. In the end, each obtained a high-quality telescope for his or her personal use. Several developed an abiding love for astronomy. The project generated much interest from technicians who didn"t initially choose to participate. In this paper I describe the project in detail.

    This project focused on developing and deploying a comprehensive program of 22 training modules, including certification requirements, and accreditation standards for commercial building technicians, to help achieve the full savings potential of energy efficient buildings, equipment, and systems. This curriculum extended the currently available commercial building technician programs -- training a labor force in a growing market area focused on energy efficiency. The program helps to remove a major market impediment to low energy/zero energy commercial building system acceptance, namely a lack of operating personnel capable of handling more complex high efficiency systems. The project developed a training curriculum for commercial building technicians, with particular focus on high-efficiency building technology, and systems. In Phase 1, the project team worked collaboratively in developing a draft training syllabus to address project objectives. The team identified energy efficiency knowledge gaps in existing programs and plans and plans to address the gaps with either modified or new curricula. In Phase 2, appropriate training materials were developed to meet project objectives. This material was developed for alternative modes of delivery, including classroom lecture materials, e-learning elements, video segments, exercises, and hands-on training elements. A Certification and Accreditation Plan and a Commercialization and Sustainability Plan were also investigated and developed. The Project Management Plan was updated quarterly and provided direction on the management approaches used to accomplish the expected project objectives. GTI project management practices tightly coordinate project activities using management controls to deliver optimal customer value. The project management practices include clear scope definition, schedule/budget tracking, risk/issue resolution and team coordination.

  16. Guidelines for training and qualification of radiological protection technicians

    International Nuclear Information System (INIS)

    1987-08-01

    These guidelines, used in combination with plant-specific job analysis, provide the framework for a training and qualification program for radiological protection technicians at nuclear power plants. Radiological protection technicians are defined as those individuals, both plant and contractor, who will be engaged in the evaluation of radiological conditions in the nuclear plant and the implementation of the necessary radiological safety measures as they apply to nuclear plant workers and members of the general public. An important aspect of this work is recognizing and handling unusual situations involving radioactivity, including incidents related to degraded core conditions. These guidelines incorporate the results of an industry-wide job analysis and task analysis (JTA) combined with industry operating experience review. However, the industry-wide analyses did not identify all important academic and fundamental knowledge and skills. Further in-depth analysis by subject matter experts produced additional knowledge and skills that were added to these guidelines. All utilities should use these guidelines in conjunction with plant-specific and industry-wide JTA results to develop or validate their radiological protection technician training program. Plant-specific information should be used to establish appropriate training program content. This plant-specific information should reflect unique job duties, equipment, operating experience, and trainee entry-level qualifications. Revisions to these guidelines should be reviewed for applicability and incorporated into the training program using each utility's training system development (TSD) procedures. Plant-specific job analysis and task analysis data is essential to the development of performance-based training programs. These analyses are particularly useful in selecting tasks for training and in developing on-the-job training (OJT), laboratory training, and mock-up training. Qualification programs based on these

    The programme was set up almost three years ago to help address a Europe-wide shortage of highly skilled technicians, with the participants gaining valuable skills and experience in an international environment. It’s clear that the programme works: some of the technician fellows who have taken part are being snapped up by major science projects and the high-tech industry.   Going underground: Fay Chicken at work in ATLAS. Fay Chicken (see UK news from CERN 59) has just accepted a job offer from the European Spallation Source in Sweden, where she will be working in the detector development team: “I’m also going to be setting up a new workshop where prototype detectors will be built. When I went to Lund, I was shown a big, empty room – it’s up to me to equip it!” This level of responsibility is a big step up for Fay, but there is no doubt that her time at CERN has both built her confidence to take on the role, and convinced ESS th...

    This report describes a project, an industry-wide Job Analysis of Nuclear Power Reactor Health Physics Technicians (HPTs), conducted by Brookhaven National Laboratory and Analysis and Technology, Inc. to provide the industry with job-performance data that can be used in systematically defining training programs in terms of required job functions responsibilities, and performance standards. The job-analysis methodology is consistent with that used by the Institute of Nuclear Power Operations (INPO) in similar industry-wide projects and includes administration of over 850 job task questionnaires to utility and contractor Health Physics Technicians throughout the country. Data collected includes task performance (difficulty, importance, and frequency) and industry-wide demographics (job levels, experience, education, and training). The results of this project discussed herein include model job descriptions for HPT positions, summaries of HPT experience, education, and training, industry-wide task listings with task-performance characteristics, and recommendations of selected tasks as a basis for HPT training development. Finally, potential future applications of the data base by utility and contractor organizations in training program development and evaluation and personnel qualifications are discussed

    The yield of H 2 from radiolysis of aqueous solutions is substantially reduced by the presence of nitrate and nitrite in the waste solutions. Nitrate is more efficient in scavenging the precursors to H 2 than is nitrite, therefore, the latter should be maintained at higher levels if minimization of radiolytic gas production is required. Nitrate is the major scavenger for e aq - and nitrite is the major scavenger for H atoms. At the concentration levels of the waste solutions some fraction of the radiation energy will be absorbed directly by the solutes, primarily the nitrate/nitrite components. Organic additive will increase the generation of H 2 and mechanistic information is available to allow predictive modeling of trends in the rate of the generation. Physical parameters such as temperature, viscosity, and pressure will not significantly affect the gas generation relative to its generation under normal conditions. Radiolytic generation of N 2 O is very inefficient in the absence of organic solutes. No mechanistic information is available on its generation in the presence of organic additives. At the concentration levels of the inorganic salts in the waste solutions, it will be very difficult to find a chemical additive that could efficiently reduce the yield of the generated H 2 , except, perhaps, increasing the concentration of the nitrite/nitrate components

    The yields of various products formed in γ-irradiated nitrate ices, viz NO 2 - , H 2 O 2 , O 2 and H 2 , have been measured at different nitrate concentrations. Daniel's method of partition of yields has been employed to evaluate the direct and indirect effect contributions to the yields of the first three products. G(H 2 ) is close to zero at all nitrate concentrations above approximately 0.5 mol dm -3 . The mechanism of product formation has been discussed in the light of various reactions put forth to explain the radiolysis of fluid aqueous nitrate solutions. The effect of various scavengers for the primary species on the product yields has also been investigated. From this it is inferred that nitrate is able to scavenge both the reducing species, viz. H and e - sub(m) giving nitrite and possibly also the holes (h + sub(m)) giving O 2 , and excited water molecules (H 2 O*) giving H 2 O 2 and additional nitrite. (author)

    Among wide application of radiation in the field of polymer chemistry, practices of polymerization, graft polymerization, bridging, etc. are introduced hereinafter. As for the radiation sources of radiation polymerization, in addition to the 60 Co-γ ray with long permeation distance which has been usually applied, electron beam accelerators with high energy, large current and high reliability have come to be produced, and the liquid phase polymerization by electron beam has attracted attention industrially. Concerning polymerizing reactions, explanations were given to electron beam polymerization under high dose rate, the polymerization in supercooling state or under high pressure, and emulsifying polymerization. As for radiation bridging, radiation is applied for the bridging of hydrogel, acceleration of bridging and improvement of radiation resistance. It is also utilized for reforming membranes by graft polymerization, and synthesis of polymers for medical use. Application of fixed enzymes in the medical field has been investigated by fixing various enzymes by low temperature γ-ray polymerization with glassy monomers such as HEMA. (Kobatake, H.)

    Detection of acid-fast bacilli in respiratory specimens serves as an initial pulmonary tuberculosis (TB) diagnosis. Laboratories are the essential and fundamental part of all health systems. This study aimed to describe how laboratory technicians perceived their own self and work. This included perceived self-efficacy, perceived role, perceived equipment availability, perceived procedures, perceived reward and job, and perceived benefit of health education, as well as level of knowledge and attitudes related to work performance of laboratory technicians. This was a cross-sectional quantitative study involving 120 laboratory technicians conducted in Central Java. Interviews and observation were conducted to measure performance and work-related variables. Among 120 laboratory technicians, 43.3% showed fairly good performance. They complied with 50%-75% of all procedures, including sputum collection, laboratory tools utilization, sputum smearing, staining, smear examination, grading of results, and universal precaution practice. Perceived role, perceived self-efficacy, and knowledge of laboratory procedures were significantly correlated to performance, besides education and years of working as a laboratory technician. Perceived equipment availability was also significantly correlated to performance after the education variable was controlled. Most of the laboratory technicians believed that they have an important role in TB patients' treatment and should display proper self-efficacy in performing laboratory activities. The result may serve as a basic consideration to develop a policy for enhancing motivation of laboratory technicians in order to improve the TB control program.

    The law is intended to define the qualifications of radiation and X-ray technicians engaging in medical treatment, and to regulate so as to maintain the proper operation of their business in order to help the popularization and development of medical treatment and public health. The radiations in this law include the following electromagnetic waves and particle beams: alpha-ray, beta-ray, gamma-ray, the electron beam with energy of more than a million electron volts, X-ray and other specified electromagnetic waves and particle beams. The terms of radiation and X-ray technicians engaging in medical treatment are stipulated, respectively. Any person who is going to be a radiation technician shall pass the examination for such technicians, and get a license from the Minister of Health and Welfare. Any person who is going to be an X-ray technician shall pass the examination for such technicians, and get a license from a prefectural governor. An insane, deaf, dumb or blind person can not receive the license. The license is realized through the registration of memberships of such technicians. A license certificate is delivered to a licensed technician by the Minister of Health and Welfare or a prefectural governor. The license is withdrawn or suspended in the occasions stipulated respectively. The examinations and practices of such technicians are specified in detail. (Okada, K.)

    Core competencies are considered the foundation for establishing Emergency Medical Technician (EMT) and paramedic curricula, and for ensuring performance standards in the delivery of prehospital care. This study surveyed EMT instructors and medical directors to identify the most desirable core competencies for all levels of EMTs in Taiwan. A principal components analysis with Varimax rotation was conducted. An online questionnaire was distributed to obtain perspectives of EMT instructors and medical directors on the most desirable core competencies for EMTs. The target population was EMT training-course instructors and medical directors of fire departments in Taiwan. The questionnaire comprised 61 competency items, and multiple-choice and open-ended questions were used to obtain respondents' perspectives of the Taiwanese EMT training and education system. The results identified three factors at EMT-1 and EMT-2 levels and five factors at the EMT-Paramedic level. The factors for EMT-1 and EMT-2 were similar, and those for EMT-Paramedics identified further comprehensive competence perspectives. The key factors that appear to influence the development of the Taiwanese Emergency Medical Services (EMS) education system are the attitude of authorities, the licensure system, and legislation. The findings present new core competencies for the Taiwanese EMT system and provide capacity to redesign curricula and reconsider roles for EMT-1 and EMT-2 technicians. At the EMT-Paramedic level, the findings demonstrate the importance of incorporating competency standards in the current skills-based curriculum. Moreover, the core-competencies gap that exists between Taiwanese EMT-1s, EMT-2s, and EMT-Paramedics and internationally recognized core competencies needs to be addressed. By identifying the key factors that potentially impact the development of the EMS education system, such as the attitude of authorities, the licensure system, and legislation, these findings will inform

  11. The Validity of Subjects in Korean Dental Technicians' Licensing Examination

    2005-06-01

    Full Text Available This study prepared a basic framework for the development and improvement of Korean Dental Technicians' Licensing Examination, based on actual test questions. A peer review was conducted to ensure relevance to current practices in dental technology. For the statistical analysis, 1000 dental laboratory technicians were selected; specialists in dental laboratory technology (laboratory owners, educators, etc. were involved in creating valid and reliable questions. Results indicated that examination subjects should be divided into three categories: basic dental laboratory theory, dental laboratory specialties, and a practical examination. To ensure relevance to current practice, there should be less emphasis on basic dental laboratory theory, including health-related laws, and more emphasis on dental laboratory specialties. Introduction to dental anatomy should be separated from oral anatomy and tooth morphology; and fixed prosthodontics should be separated from crown and bridge technology and dental ceramics technology. Removable orthodontic appliance technology should be renamed 'orthodontic laboratory technology'. There should be less questions related to health related law, oral anatomy, dental hygiene, dental materials science and inlay, while the distribution ratio of questions related to tooth morphology should be maintained. There should be a decrease in the distribution ratio of questions related to crown and bridge technology, dental ceramics technology, complete dentures and removable partial dentures technology, and orthodontic laboratory technology. In the practical examination, the current multiple choice test should be replaced with tooth carving using wax or plaster. In dental laboratory specialties, subjects related to contemporary dental laboratory technology should be included in the test items.

    Neonatal intensive care nurses have historically been responsible for preparing enteral feedings--a costly and time-consuming process that may require leaving the bedside. To address these concerns, the Milk Technician Program was implemented at a major military treatment facility. Milk technicians were specially trained and responsible for handling, storing, and preparing enteral feeds. To determine effectiveness of the Milk Technician Program, changes in length of time required to first attain full feeds, cost of feeding preparation, adherence to feeding preparation procedures, and nurse and milk technician role variables were evaluated. A pre-/postdesign was used to compare length of time to full enteral feedings and cost. A plan-do-study-act design was used to evaluate protocol adherence and to identify and evaluate nurse and milk technician role variables. Data were collected via surveys, direct observations, and retrospective chart reviews to determine the overall effectiveness of this intervention. The average time for extremely and very preterm infants (milk technician adherence to preparation procedures was 95.5%. Most nurses reported that the program saved time (97%) and all milk technicians reported improved job satisfaction. Nurses expressed concerns about accuracy and safety of preparation. Milk technicians reported concerns with communication, supplies, and lack of perceived support. Milk technicians offer significant benefit to infants and nurses in the neonatal intensive care unit, including reducing time for infants to reach full feeds, saving nurses' time, and reducing costs. Further research is needed to identify ideal educational backgrounds for milk technicians and to directly measure the effect of milk technicians on hospital length of stay and infant growth parameters.

    Full Text Available Effective workplace-based interventions after critical incidents (CIs are needed for emergency medical technicians (EMT/paramedics. The evidence for a period out of service post-CI (downtime is sparse; however it may prevent posttraumatic stress disorder (PTSD and burnout symptoms. We examined the hypothesis that downtime post-CI is associated with fewer symptoms of four long-term emotional sequelae in EMT/paramedics: depression, PTSD, burnout, and stress-related emotional symptoms (accepted cut-offs defined high scores. Two hundred and one paramedics completed questionnaires concerning an index CI including downtime experience, acute distress, and current emotional symptoms. Nearly 75% received downtime; 59% found it helpful; 84% spent it with peers. Downtime was associated only with lower depression symptoms, not with other outcomes. The optimal period for downtime was between 1 day being less effective. Planned testing of mediation of the association between downtime and depression by either calming acute post-CI distress or feeling helped by others was not performed because post-CI distress was not associated with downtime and perceived helpfulness was not associated with depression. These results suggest that outcomes of CIs follow different pathways and may require different interventions. A brief downtime is a relatively simple and effective strategy in preventing later depression symptoms.

  3. Management perceptions of the Health Physics Technician job

    Mazour, T.J.; Marotta, F.J.

    1985-12-01

    In 1984, an industry-wide job analysis of nuclear power reactor Health Physics Technicians (HPTs) was completed. These results provided the basis for job descriptions, industry-wide task listings and recommendations for task selections for further analysis and formal training. A total of 389 tasks were identified and reviewed by 850 HPTs representing 39 plants and 6 vendor companies. Constructive criticism of the HPT job analysis focused on the fact that HPT supervisors and managers were not included in the survey. Concerns were addressed that these supervisors/managers might have a divergent perception of the HPT job that could lead to different conclusions than those that were originally drawn. The only way to confirm (or deny) this hypothesis was to verify the results of the job analysis of HPTs by also surveying radiation protection management personnel. A total of 19 HPT supervisors/managers completed the same survey that had been used for HPT job incumbents. They were asked to rate each task on the basis of their job incumbents' performance of the task. Of the 1161 ratings (389 tasks each with a rating for frequency, difficulty, and importance), only 37 of the ratings differed between the HPTs and the HPT supervisors/managers (at the 99% confidence level)

  5. Guidebook on the education and training of technicians for nuclear power

    International Nuclear Information System (INIS)

    1989-01-01

    The IAEA Guidebook on the Education and Training of Technicians for Nuclear Power aims to assist Member States, especially the developing countries which are in the process of implementing, or intending to implement, a nuclear power programme, to understand and meet their requirements for qualified technicians in the most effective and efficient manner. It specifically seeks to assist policy makers and planners, as well as those designing and implementing education and training programmes. In this Guidebook, technician level occupations include those filled by technicians and higher level technicians (techniciens superieurs or technologists) and also by non-graduate engineers. The Guidebook complements the IAEA Guidebook on Manpower Development for Nuclear Power, as well as the IAEA Guidebook on the Qualification of Nuclear Power Plant Operations Personnel. The key objectives of this Guidebook are to describe: (1) the level and content of conventional education and training which a technician must have before nuclear oriented education and training can begin; (2) the level and content of nuclear oriented education and training; (3) measures to bridge the gap between the education and training acquired by technicians in the national technical schools (i.e. the level attained before upgrading) and the level of education and training qualifications needed for technicians to work in the nuclear power programme (i.e. the level attained after completion of nuclear oriented education and training). Valuable information on the national experiences of IAEA Member States in the education and training of technicians for nuclear power, as well as examples of such education and training from various Member States, are included in IAEA-TECDOC-526, which should be read in conjunction with the present text. 3 refs, 13 figs, 3 tabs

    The frequency of hypoxanthine phosphoribosyl transferase (HPRT) mutants among peripheral T-lymphocytes of radiotherapy technicians primarily exposed to 60Co was measured by the T-cell cloning method. Mutant frequencies of these technicians in 1984 and 1986 were significantly higher than those of physiotherapy technicians who worked in a neighboring service, and correlated significantly with thermoluminescence dosimeter readings recorded during the 6 mo preceding mutant frequency determination. Correlations decreased when related to dose recorded over longer time intervals. HPRT mutant frequency determination in peripheral lymphocytes is a good measure of recently received biologically effective radiation dose in an occupationally exposed population.

    We sought to develop a reliable and valid tool for measuring teamwork among emergency medical technician (EMT) partnerships. We adapted existing scales and developed new items to measure components of teamwork. After recruiting a convenience sample of 39 agencies, we tested a 122-item draft survey tool (EMT-TEAMWORK). We performed a series of exploratory factor analyses (EFAs) and confirmatory factor analysis (CFA) to test reliability and construct validity, describing variation in domain and global scores using descriptive statistics. We received 687 completed surveys. The EFAs identified a nine-factor solution. We labeled these factors 1) Team Orientation, 2) Team Structure & Leadership, 3) Partner Communication, Team Support, & Monitoring, 4) Partner Trust and Shared Mental Models, 5) Partner Adaptability & Back-Up Behavior, 6) Process Conflict, 7) Strong Task Conflict, 8) Mild Task Conflict, and 9) Interpersonal Conflict. We tested a short-form (30-item SF) and long-form (45-item LF) version. The CFAs determined that both the SF and the LF possess positive psychometric properties of reliability and construct validity. The EMT-TEAMWORK-SF has positive internal consistency properties, with a mean Cronbach's alpha coefficient ≥0.70 across all nine factors (mean = 0.84; minimum = 0.78, maximum = 0.94). The mean Cronbach's alpha coefficient for the EMT-TEAMWORK-LF was 0.87 (minimum = 0.79, maximum = 0.94). There was wide variation in weighted scores across all nine factors and the global score for the SF and LF. Mean scores were lowest for the Team Orientation factor (48.1, standard deviation [SD] 21.5, SF; 49.3, SD 19.8, LF) and highest (more positive) for the Interpersonal Conflict factor (87.7, SD 18.1, for both SF and LF). We developed a reliable and valid survey to evaluate teamwork between EMT partners.

The Medical Communications department within Genentech uses a skills-mix staffing model in which employees with varying educational and training backgrounds work as a team on meeting the informational needs of consumers and health professionals who contact the company. One position within the department is that of Medical Communications Associate, responsible primarily for managing product inquiries. Medical Communications Associates have degrees in life sciences or an equivalent combination of education and experience, including a minimum of 2 years of related experience in the health care industry. Currently, four of the seven Medical Communications Associates in the department are CPhTs. Not applicable. Ability to recruit CPhTs for Medical Communications Associate positions, and job satisfaction of those hired into these positions. Critical basic skills needed for the Medical Communications Associate position include strong computer literacy, ability to multitask, and ability to work in an environment with frequent interruptions. Strong oral and written communications skills, customer service skills, ability to deal with stressful situations, product-specific knowledge, ability to work on a daily basis with Medical Communications Pharmacists, and knowledge of medical terminology are also important. The skills set of CPhTs matches these requirements, as evidenced by the experiences of the four staff members who have worked in the department for a total of 17 person-years. This nontraditional role for CPhTs can be rewarding and beneficial to all, affording an unique opportunity within the pharmaceutical industry. The skill set and experience of CPhTs can be used in the nontraditional pharmacy practice setting of drug information.

Methods We adapted existing scales and developed new items to measure components of teamwork. After recruiting a convenience sample of 39 agencies, we tested a 122-item draft survey tool. We performed a series of Exploratory Factor Analyses (EFA) and Confirmatory Factor Analysis (CFA) to test reliability and construct validity, describing variation in domain and global scores using descriptive statistics. Results We received 687 completed surveys. The EFA analyses identified a 9-factor solution. We labeled these factors [1] Team Orientation, [2] Team Structure & Leadership, [3] Partner Communication, Team Support, & Monitoring, [4] Partner Trust and Shared Mental Models, [5] Partner Adaptability & Back-Up Behavior, [6] Process Conflict, [7] Strong Task Conflict, [8] Mild Task Conflict, and [9] Interpersonal Conflict. We tested a short form (30-item SF) and long form (45-item LF) version. The CFA analyses determined that both the SF and LF versions possess positive psychometric properties of reliability and construct validity. The EMT-TEAMWORK-SF has positive internal consistency properties with a mean Cronbach’s alpha coefficient ≥0.70 across all 9-factors (mean=0.84; min=0.78, max=0.94). The mean Cronbach’s alpha coefficient for the EMT-TEAMWORK-LF version was 0.87 (min=0.79, max=0.94). There was wide variation in weighted scores across all 9 factors and the global score for the SF and LF versions. Mean scores were lowest for the Team Orientation factor (48.1, SD 21.5 SF; 49.3 SD 19.8 LF) and highest (more positive) for the Interpersonal Conflict factor (87.7 SD 18.1 for both SF and LF). Conclusions We developed a reliable and valid survey to evaluate teamwork between EMT partners. PMID:22128909

    This is a qualitative, exploratory and descriptive study whose general objective was to learn, considering the perspective of the nursing technician who works in school hospitals, the competencies developed during their educational process to implement the Nursing Care Systematization (NCS). Data collection and analysis were carried out through a focal group, with content analysis and nursing technicians. Two thematic categories emerged: The participation of the nursing technician in the NCS and The competencies in the education of the nursing technician. Each one received two subcategories: Conception of the NCS and (De)valuation of the NCS, Technical-scientific competency and Competency in the interpersonal relationship, respectively. It was observed that the NCS must be shared, discussed and made public among nursing professionals, so that they may acknowledge themselves as the leading actors of their methodology and be aware that their practices determine the results.

    Statement of the problem Digital workflows (CAD/CAM) have been introduced in dentistry during recent years. No published information exists on dental technicians' use and reporting of this technology.Purpose The aim of this cross sectional survey was to identify the extent digital technology has infiltrated the workplace and to investigate the factors affecting the use of CAD-CAM technology by dental laboratory technicians within Ireland and the UK.Materials and methods A web-based questionnaire was composed (Opinio, Object Planet Inc. Oslo, Norway) and distributed to UK and Irish dental technicians. Answers to all questions were anonymous and grouped such that general information was gathered initially, followed by branching of the survey into two sections depending on whether or not the respondent worked with CAD-CAM technology. Results were compiled and statistical analysis (Fisher's Exact test, SPSS, IBM, Armonk, New York, USA) was performed in order to investigate any correlation between various demographic variables and the answers provided.Results The survey was distributed to 760 UK technicians and 77 Irish technicians. The total number of completed surveys was 105, which yielded a total response rate of 14%. Most technicians reported using some form of CAD/CAM aspect in the workflow, and this was more significant for technicians working in large laboratories. Most training received was company-led. Large laboratories were also significantly correlated with less outsourcing of CAD/CAM work and a change in dental material use leading to the increase of zirconia and the decrease of noble alloys. Dental technicians did not report any significant change in working relationships and staffing as a result of CAD/CAM incorporation. High initial investment cost was the most common reason quoted from non-users, along with the lack of such technology in their working environment.

    As part of a study of radiolytic degradation of pharmaceuticals during radiosterilization, the basic radiation chemistry of the B-group vitamins, nicotinamide, pyridoxin, riboflavin and thiamine, and the reaction of hydrogen peroxide with these same materials has been investigated. The various aspects studied were - radiolysis under controlled conditions, effects of phase, temperature, pH and nature and concentration of additives. Some of the conclusions are: 1) with oxygen saturated aqueous solutions containing glucose, the radiolytic degradation of the vitamins is reduced: 2) results a similar for N 2 O saturated aqueous solutions; 3) in glucose-containing solutions, the protective effect is considerably modified at higher temperatures; and 4) irradiation of air-saturated aqueous solutions in the frozen state leads to reduced decomposition. It is concluded that in the presence of oxygen, in frozen matrices at low temperature, it appears possible to reduce the radiolytic breakdown of vitamins to low levels

    2012-06-01

    Under the 2003 Health Practitioners Competence Assurance (HPCA) Act, New Zealand registered dental technicians are subject to mandatory Continuing Professional Development (CPD) requirements. Internationally, little published literature has examined dental technicians' perspectives of CPD and CPD needs, and there is no published literature relating to the New Zealand context. Available research highlights the importance of CPD for maintaining high professional standards, ensuring patient safety, allowing dental technicians to keep abreast of current research and technological advances, fostering peer networks, and promoting job satisfaction. In 2009, an online open-ended questionnaire was developed to examine New Zealand dental and clinical dental technicians' perspectives of CPD and their perceived CPD needs. In total, 45 New Zealand registered dental technicians responded. Questionnaire responses provided rich qualitative insights into dental technicians' wide-ranging perceptions of CPD, factors that make CPD involvement more or less difficult and more or less desirable, and ways in which CPD access and relevance might be improved. This paper discusses the survey findings in the light of the existing literature on CPD and in relation to the unique New Zealand regulatory environment. It highlights the factors which respondents identified as shaping their CPD decisions, barriers to CPD engagement, perceived CPD needs, suggestions as to how the current CPD system could be improved, and areas for future research.

    Over the last 30 years, Lawrence Livermore National Laboratory (LLNL) has successfully implemented the concept of a multi-disciplined technician. LLNL Health and Safety Technicians have responsibilities in industrial hygiene, industrial safety, health physics, as well as fire, explosive, and criticality safety. One of the major benefits to this approach is the cost-effective use of workers who display an ownership of health and safety issues which is sometimes lacking when responsibilities are divided. Although LLNL has always promoted the concept of a multi-discipline technician, this concept is gaining interest within the Department of Energy (DOE) community. In November 1992, individuals from Oak Ridge Institute of Science and Education (ORISE) and RUST Geotech, joined by LLNL established a committee to address the issues of Health and Safety Technicians. In 1993, the DOE Office of Environmental, Safety and Health, in response to the Defense Nuclear Facility Safety Board Recommendation 91-6, stated DOE projects, particularly environmental restoration, typically present hazards other than radiation such as chemicals, explosives, complex construction activities, etc., which require additional expertise by Radiological Control Technicians. They followed with a commitment that a training guide would be issued. The trend in the last two decades has been toward greater specialization in the areas of health and safety. In contrast, the LLNL has moved toward a generalist approach integrating the once separate functions of the industrial hygiene and health physics technician into one function

    The creation of a clinical support role for a pharmacy technician within a primary care resource center is described. In the Primary Care Resource Center (PCRC) Project, hospital-based care transition coordination hubs staffed by nurses and pharmacist teams were created in 6 independent community hospitals. At the largest site, patient volume for targeted diseases challenged the ability of the PCRC pharmacist to provide expected elements of care to targeted patients. Creation of a new pharmacy technician clinical support role was implemented as a cost-effective option to increase the pharmacist's efficiency. The pharmacist's work processes were reviewed and technical functions identified that could be assigned to a specially trained pharmacy technician under the direction of the PCRC pharmacist. Daily tasks performed by the pharmacy technician included maintenance of the patient roster and pending discharges, retrieval and documentation of pertinent laboratory and diagnostic test information from the patient's medical record, assembly of patient medication education materials, and identification of discrepancies between disparate systems' medication records. In the 6 months after establishing the PCRC pharmacy technician role, the pharmacist's completion of comprehensive medication reviews (CMRs) for target patients increased by 40.5% ( p = 0.0223), driven largely by a 42.4% ( p team extended the reach of the pharmacist and allowed more time for the pharmacist to engage patients. Technician support enabled the pharmacist to complete more CMRs and reduced the time required for chart reviews. Copyright © 2018 by the American Society of Health-System Pharmacists, Inc.

    1976-01-01

    The workshop was held to exchange information on existing facilities and programmes in Asia and the Pacific for training nuclear laboratory technicians, to identify future training needs and to assess the need for IAEA's involvement in this field. As the participants outlined the requirements for nuclear laboratory technician training and the facilities available in their respective countries, it became evident that, in addition to the training of radioisotope laboratory technicians, they also wished to review the need for technician training for the operation of nuclear power plants and industrial application of atomic energy. The terms of reference of the workshop were extended accordingly. The opening address by Chang Suk Lee, the Korean Vice Minister of Science and Technology, noted the valuable contribution to quality control and other industrial uses that nuclear techniques have made in his country. He also reviewed the application of nuclear techniques in Korean agriculture and medicine. The participants explored various forms of co-operation that could be established between countries of the region. Exchange programmes, not only for students but also for expert teachers, and the exchange or loan of equipment were suggested. It was felt that some generalized training courses could be organized on a regional basis, and two countries advocated the setting up of a regional training centre. One suggestion was to arrange regional training courses in special fields that would move from one country to another. The need was felt for periodic regional meetings on training methods, course content and other questions relating to training of laboratory technicians. The IAEA was requested to act as a clearinghouse for information on available training facilities in the region and to advise on the curricula for technician training courses. The Agency was also asked to organize short courses for the training of instructors of technicians in the various fields of atomic

It's purpose is providing professional training of students in the area of diagnostic imaging, nuclear medicine and radiotherapy. Practical training is based on the scientific and theoretical knowledge and skills and is organized in pedagogic environment, adequate to regularities for a gradual formation of practical skills and habits. The practical training and pre-graduation internship are performed in 1895 from total of 3810 hours, which represents about fifty percent of all training of X-ray technicians. Students are in groups of 2-4 students. Practical training is organized, accomplished and monitored by the teacher training practice with the help of a mentor in the clinical base. Purpose: To present the tasks of practical training of students - X-ray technicians and the requirements for the personal characteristics and activity of mentors. Materials and methods: Documentary method has been used. Literature and normative documents related to the practical training of students in 'X-ray technician' of Medical Colleges have been studied. The job descriptions of senior clinical X-ray technicians have been examined carefully. Results: By analyzing literature sources, we have structured the tasks of practical training and pre-graduation internship of students - X-ray technicians, also we have described the requirements for personal qualities of mentors and systematize the activities they perform. Conclusion: Practical training plays an important role in adaptation of young X-ray technicians to the conditions of medical work, improving their skills and habits, and to the development of specific practical skills for being able to respond to emergency conditions and to solve complicated practical situations. The mentor is the supervisor and the controller of interns who helps this happen through his own example, qualities and attitudes towards

    There are many implant cases in which dental technicians take initiative with regard to the design of implant prostheses, and to a certain extent, this area of care is one in which dentists do not necessarily play the leading role. Moreover, inadequate communication between dental technicians and dentists and insufficient instructions for technicians has been highlighted as issues in the past. The purpose of this questionnaire is to improve the quality of implant prostheses and thereby contribute to patient service by clarifying, among other aspects of treatment, problem areas and considerations in the fabrication of implant prostheses, conceptual-level knowledge, and awareness of prosthodontics on the part of the dentists in charge of treatment and methods for preventing prosthetic complications. A cross-sectional survey was given to 120 certified dental technicians. To facilitate coverage of a broad range of topics, we classified the survey content into the following four categories and included detailed questions for (1) the conditions under which implant technicians work, (2) implant fixed prostheses, (3) implant overdentures, and (4) prosthetic complications. Out of 120 surveys sent, 74 technicians responded resulting in a response rate of 61.6%. This survey served to clarify the current state of implant prosthodontics, issues, and considerations in the fabrication of implant prostheses, and the state of prosthetic complications and preventive initiatives, all from a laboratory perspective. The results of this survey suggested that, to fabricate prostheses with a high level of predictability, functional utility, and aesthetic satisfaction, it is necessary to reaffirm the importance for dentists to increase their prosthetic knowledge and work together with dental technicians to develop comprehensive treatment plans, implement an organized approach to prosthesis design, and accomplish occlusal reconstruction.

    Pharmacy technicians are a vital part of the health care workforce. Little is known about perceptions of their own work environment that would engender more effective recruitment, retention, and management strategies by pharmacists and employers. The purpose of this study was to gain a greater understanding of certified pharmacy technician worklife. Specific objectives included the identification of themes of worklife phenomena to assist with the development of appropriate responses by other pharmacy stakeholders and to ascertain the contribution of various factors engendering or discouraging career commitment of pharmacy technicians. Semi-structured in-depth interviews were carried out with a convenience sample of pharmacy technicians in one U.S. state, who varied by their work settings and level of experience. The interview guide and corresponding participant responses were framed from around an organizational cultural basis rooted in organizational behavior theory. Notes from the interviews were analyzed thematically using directed content analysis. Four primary themes emerged, including: career impetus, job responsibilities, quality of work life, and equitable partnership. The data revealed pharmacy technicians' need for self-actualization and recognition of the value they bring to the organization. The participants identified primary responsibilities that contribute to their sense of worth and those that if not managed adequately potentially detract from their well-being and effectiveness. Findings in regard to rate of pay corroborate previous work on wages as both an intrinsic and extrinsic motivator. Pharmacy technicians seek equity among each other (their peers) and in a mutually beneficial relationship with their employing organization. This study provides the impetus for interventions and further study that should serve to enhance pharmacy technician effectiveness, quality of work life, and longevity in an emerging profession.

    Norcross, Robert

    Aircraft maintenance technician decision-making and actions have resulted in aircraft system errors causing aircraft incidents and accidents. Aircraft accident investigators and researchers examined the factors that influence aircraft maintenance technician errors and categorized the types of errors in an attempt to prevent similar occurrences. New aircraft technology introduced to improve aviation safety and efficiency incur failures that have no information contained in the aircraft maintenance manuals. According to the Federal Aviation Administration, aircraft maintenance technicians must use only approved aircraft maintenance documents to repair, modify, and service aircraft. This qualitative research used a grounded theory approach to explore the decision-making processes and actions taken by aircraft maintenance technicians when confronted with an aircraft problem not contained in the aircraft maintenance manuals. The target population for the research was Federal Aviation Administration licensed aircraft and power plant mechanics from across the United States. Nonprobability purposeful sampling was used to obtain aircraft maintenance technicians with the experience sought in the study problem. The sample population recruitment yielded 19 participants for eight focus group sessions to obtain opinions, perceptions, and experiences related to the study problem. All data collected was entered into the Atlas ti qualitative analysis software. The emergence of Aircraft Maintenance Technician decision-making themes regarding Aircraft Maintenance Manual content, Aircraft Maintenance Technician experience, and legal implications of not following Aircraft Maintenance Manuals surfaced. Conclusions from this study suggest Aircraft Maintenance Technician decision-making were influenced by experience, gaps in the Aircraft Maintenance Manuals, reliance on others, realizing the impact of decisions concerning aircraft airworthiness, management pressures, and legal concerns

    The aim of this study was to compare the occlusal morphology of partial crown reconstructions made by dental technicians with reconstructions made by a fully automatic software process (biogeneric tooth model) in relation to the original natural tooth shape. Stone replicas of natural teeth were measured three-dimensionally before preparing inlay and onlay cavities for ceramic restorations (n = 5). For each preparation, five reconstructions (in total n = 25) were made by five dental technicians. Additionally, reconstructions were calculated automatically by a software based on the biogeneric tooth model (Cerec 3D). In order to compare the two different kinds of reconstruction, an objective metrical similarity measure (shape similarity value, SSV) based on calculated volumes between compared datasets was used. In 22 of 25 cases, the reconstructions made by the CAD software were closer to the original situation than the reconstructions made by the technicians. Mean average SSV of reconstructions made by the technicians (310.2 ± 78.8 μm) was significantly higher (p dental technicians. The adjustment of a dental restoration to fit the morphology of surrounding tooth structures, still presents challenges for the dentist.

    Lower back pain (LBP) is the most common complaint worldwide and the leading cause of disability in the workplace. In Colombia there are no epidemiological data on low back pain in aviation. This study aimed to characterize lower back pain in pilots and maintenance technicians in a Colombian commercial airline. Information was collected from the total population in a Colombian commercial airline in Bogota during the period from 2011 to 2013 using a voluntary survey which requested demographics, occupational (LEST survey) factors, back pain, and chronic pain (chronic pain grade scale). The prevalence rate of LBP in pilot respondents was 71% and the factors associated previously have belonged to the military forces: occupational exposure to physical load and work time. Chronic low back pain was at a prevalence of 49%. The prevalence of LBP in maintenance technicians was 65%. Associated factors were again similar to military forces and included mental workload. Chronic pain had a prevalence of 65%. Factors associated with chronic low back pain were the technicians' time in office and physical load. The prevalence of lower back pain in pilots is similar to that presented in the airline world population. In the case of maintenance technicians, the prevalence was higher than those found in other similar groups, but very similar to prevalences presented in different business industries, including the transport sector.

    Full Text Available This is a review of the role of practical work in UK’s secondary school science lessons, the impact that practical work has in the promotion of science, the challenges created through use of non-specialist science teachers and a possible additional role for science technicians. The paper considers how improved deployment of suitably experienced school science technicians and their recognition, by schools’ management, for their involvement in the delivery of training in the use of practical work, for less experienced teachers, could benefit schools and their students. This together with its companion paper endeavours to show how the more effective use of practical work and technicians can encourage more students to select science at higher, non-compulsory levels.

    Different perspectives on the role of mid-level workers in health care might represent a constraint to health policies. This study aimed to investigate how different agents view the participation of oral health technicians in direct activities of oral healthcare with the goal of understanding the related symbolic dispositions. Theoretical assumptions related to inter-professional collaboration and conflicts in the field of healthcare were used for this analysis. A researcher conducted 24 in-depth interviews with general dental practitioners, oral health technicians and local managers. The concepts of Pierre Bourdieu supported the data interpretation. The results indicated inter-professional relations marked by collaboration and conflict that reflect an action space related to different perspectives of primary care delivery. They also unveiled the symbolic devices related to the participation of oral health technicians that represent a constraint to the implementation of oral health policy, thus reducing the potential of primary health care in Brazil.

    Full Text Available Objectives: It has been reported that supportive personnel, such as pharmacy technicians, are key participants in the use of health information technology. The purpose of this study was to describe how pharmacy technicians use e-prescribing and to explore the characteristics of technicians that support pharmacists in ensuring patient safety. Methods: This was a qualitative study that used observations, interviews, and focus groups to understand the role of pharmacy technicians in e-prescribing. Fourteen pharmacy technicians and 13 pharmacists from five community pharmacies participated. Observations lasted about nine hours in each pharmacy. Follow-up interviews and two separate focus groups were later conducted. Observation field notes and audio recordings were transcribed and thematically analyzed. Results: Pharmacy technicians were primarily responsible for all steps leading up to pharmacist review of the e-prescription and dispensing of medications to the patient. Technician characteristics, including experience, certification status, and knowledge of appropriate medication use, were reported as important factors in supporting a pharmacist’s role in ensuring patient safety with the use of e-prescribing. Conclusion: Study findings indicate that pharmacy technicians have an important role in supporting pharmacists to prevent medication errors. Certain characteristics of pharmacy technicians were identified with the potential to improve the e-prescription medication dispensing process and decrease patient harm through the identification and resolution of errors.

    To determine occupational association with metabolic syndrome among auto technicians and school teachers. One hundred and sixty six subjects were selected for this study. Clinical data was obtained while laboratory investigations including plasma glucose and lipid profile were performed. Statistical analysis was done with SPSS 20.0. Pauto technicians. Mean serum triglycerides was significantly higher among auto-technicians compared to school teachers in this study. The prevalence of some conventional cardiovascular risk factors was significantly higher among auto-technicians compared to school teachers: Impaired blood glucose (9.6% vs. 1.2%, pauto-technicians. Based on the WHO and the Harmonized criteria, metabolic syndrome was more frequent among auto-technicians compared to school teachers. (8.4% vs. 1.2% and 19.3% vs. 7.2% respectively, pauto technicians despite their high level of physical activity, exertion and education compared to teachers. This may be related to the increased occupational exposure to organic and inorganic materials from dust particles, oil and oil related matter and particulate matter among auto technicians. Prompt definitive evaluation of this concept and appropriate health education to encourage safety mechanism can reduce this burden of metabolic syndrome among auto technicians in Nigeria.

    This paper address the phenomenon of drones and their potential relationship with the city from the point of view of the so-called “mobilities turn”. This is done in such a way that turns attention to a recent redevelopment of the “turn” towards design; so the emerging perspective of “mobilities...... design” will be used as a background perspective to reflect upon the future of drones in cities. The other perspective used to frame the phenomenon is the emerging discourse of the “smart city”. A city of proliferating digital information and data communication may be termed a smart city as shorthand...... for a new urban condition where cities are networked and connected (as well as disconnected) from the local block to global digital spheres.

    Vatican City, the administrative and spiritual capital of the Roman catholic Church, has a population of 1000. Citizenship is generally accorded only to those who reside in Vatican City for reasons of office of employment. Supreme legislative, executive, and judicial power is currentily exercised by Pope John Paul II, the 1st non-italian pope in 5 centuries. The State of Vatican City is recognized by many nations as an independent sovereign state under the temporal jurisdiction of the Pope. By 1984, 108 countries had established diplomatic relations with the Holy See, most of which are not Roman Catholic. Third World countries comprise a large proportion of countries that have recently established relations with the Holy See. The US re-established relations with the Vatican in 1984 and there is frequent contact and consultation between the 2 states on key international issues.

    Full Text Available BACKGROUND: Internet-based cognitive behavioural therapy (iCBT for depression is effective when guided by a clinician, less so if unguided. QUESTION: Would guidance from a technician be as effective as guidance from a clinician? METHOD: Randomized controlled non-inferiority trial comparing three groups: Clinician-assisted vs. technician-assisted vs. delayed treatment. Community-based volunteers applied to the VirtualClinic (www.virtualclinic.org.au research program, and 141 participants with major depressive disorder were randomized. Participants in the clinician- and technician-assisted groups received access to an iCBT program for depression comprising 6 online lessons, weekly homework assignments, and weekly supportive contact over a treatment period of 8 weeks. Participants in the clinician-assisted group also received access to a moderated online discussion forum. The main outcome measures were the Beck Depression Inventory (BDI-II and the Patient Health QUESTIONnaire-9 Item (PHQ-9. Completion rates were high, and at post-treatment, both treatment groups reduced scores on the BDI-II (p<0.001 and PHQ-9 (p<0.001 compared to the delayed treatment group but did not differ from each other. Within group effect sizes on the BDI-II were 1.27 and 1.20 for the clinician- and technician-assisted groups respectively, and on the PHQ-9, were 1.54 and 1.60 respectively. At 4-month follow-up participants in the technician group had made further improvements and had significantly lower scores on the PHQ-9 than those in the clinician group. A total of approximately 60 minutes of clinician or technician time was required per participant during the 8-week treatment program. CONCLUSIONS: Both clinician- and technician-assisted treatment resulted in large effect sizes and clinically significant improvements comparable to those associated with face-to-face treatment, while a delayed treatment control group did not improve. These results provide support for large

    This research initiative CITY 2020+ assesses the risks and opportunities for residents in urban built environments under projected demographic and climate change for the year 2020 and beyond, using the City of Aachen as a case study. CITY 2020+ develops scenarios, options and tools for planning and developing sustainable future city structures. We investigate how urban environment, political structure and residential behavior can best be adapted, with attention to the interactions among structural, political, and sociological configurations and with their consequences on human health. Demographers project that in the EU-25-States by 2050, approximately 30% of the population will be over age 65. Also by 2050, average tem¬peratures are projected to rise by 1 to 2 K. Combined, Europe can expect enhanced thermal stress and higher levels of particulate matter. CITY 2020+ amongst other sub-projects includes research project dealing with (1) a micro-scale assessment of blockages to low-level cold-air drainage flow into the city centre by vegetation and building structures, (2) a detailed analysis of the change of probability density functions related to the occurrence of heat waves during summer and the spatial and temporal structure of the urban heat island (UHI) (3) a meso-scale analysis of particulate matter (PM) concentrations depending on topography, local meteorological conditions and synoptic-scale weather patterns. First results will be presented specifically from sub-projects related to vegetation barriers within cold air drainage, the assessment of the UHI and the temporal and spatial pattern of PM loadings in the city centre. The analysis of the cold air drainage flow is investigated in two consecutive years with a clearing of vegetation stands in the beginning of the second year early in 2010. The spatial pattern of the UHI and its possible enhancement by climate change is addressed employing a unique setup using GPS devices and temperature probes fixed to

    Full Text Available This paper reports the results of a study made on the impact of improved deployment of science technicians in the classroom could directly benefit students in practical science investigations. Science technicians are skilled individuals whose understanding of practical work is a valuable resource not being used of in support of students understanding of science. Aspects of practical work and technician support were scrutinised, through information attained from a post-16 student survey to improve understanding about this teaching tool, to establish if it was being used to its full potential within science lessons. Analysis was also made of students’ perceptions of school science. The main outcomes were that the majority of students enjoyed science practical work and felt that science could not be taught without it. Students studying science at pre-university level attained a greater understanding, through participating in relevant practical work, than students who had studied it at earlier, compulsory levels. Students reported that science technicians provide impact on student learning when contact time was the greatest.

    There is paucity of data on the inter-observer agreement and diagnostic accuracy between a primary-care technician (vision technician) and an ophthalmologist. Hence, the current study was conducted to assess the accuracy of vision technicians, to screen potentially sight-threatening ocular conditions at rural vision centres of southern India and their agreement with an ophthalmologist. In July to August 2010, patients presenting to seven vision centres in Adilabad district (Andhra Pradesh) were selected and screened in a masked manner by seven vision technicians followed by an examination by a consultant ophthalmologist. Agreement was assessed between vision technicians and the ophthalmologist for screening of potential sight-threatening ocular conditions and decisions for referral. The ophthalmologist's findings were considered as the reference standard. Two hundred and seventy-nine patients were enrolled at seven vision centres with a mean age of 32.9 ± 21.8 years.

    Over the last decade, climate change has moved from being the concern of few to a widely recognized threat to humanity itself and the natural environment. The 1990s were the warmest decade on record, and ever-increasing atmospheric levels of greenhouse gases such as carbon dioxide (CO/sub 2/), could, if left unchecked lead to serious consequences globally, including increased risks of droughts, floods and storms, disruption to agriculture, rising sea levels and the spread of disease. The contribution of anthropogenic emissions of carbon dioxide has been recognized as the principal cause of the atmospheric changes that drive these climate trends. Globally, buildings are the largest source of indirect carbon emissions. In 2000, the UK Royal Commission on Environmental Pollution estimated that in order to stabilise carbon emissions at levels, which avoid catastrophic alterations in the climate, we would have to reduce emissions from the built environment by at least 60% by 2050 and 80% by 2100 relative to 1997 levels. Studies of the Oxford Ecohouse have demonstrated that it is not difficult to reduce carbon emissions from houses by 60% or more through energy efficiency measures, but it is only possible to reach the 90% level of reductions required by using renewable energy technologies. Solar energy technologies have been the most successfully applied of all renewable to date largely because they are the only systems that can be incorporated easily into the urban fabric. In addition, the short fossil fuel horizons that are predicted (c. 40 years left for oil and 65 years for gas) will drive the markets for solar technologies. For these reasons, the cities of the future will be powered by solar energy, to a greater or lesser extent, depending on the city form and location. In recognition of the need to move rapidly towards a renewable energy future, a group of international cities, including Oxford, have started the Solar City Network. In this paper we outline the

    The goals of this study were to develop and evaluate a joint theoretical/practical training course for radiology residents and technicians and to start a collaborative practice agreement enabling radiology technicians to perform PICC placement under the responsibility of an interventional radiologist. A joint training session based on literature evidences and international recommendations was designed. Participants were assessed before and after training, and were also asked to evaluate the program one month after completion of the training course. Practical post-training mentoring guidelines were laid down for radiologists supervising technicians. From January to April 2014, 6 radiology residents and 12 radiology technicians from the two interventional radiology departments of the University hospitals in Marseille took part in the training program. For both residents and technicians, significant improvement was observed between pretraining and post-training assessment. The majority of participants were satisfied with the program. Our experience suggests that combined theoretical and practical training in PICC placement allows improving technical skill and yields high degrees of satisfaction for both radiology residents and technicians. A collaborative practice agreement is now formally established to enable radiologists to delegate PICC placement procedures to radiology technicians.

    The effect of ionizing radiations on aqueous solutions leads to water ionization and then to the formation of radical species and molecular products (e{sup -}{sub aq}, H{sup .}, OH{sup .}, H{sub 2}O{sub 2}, H{sub 2}). It has been shown that the stopping power, characterized by the LET value (Linear Energy Transfer) becomes different when the nature of the ionizing radiations is different. Few data are nowadays available for high LET radiations such as protons and high energy heavy ions. These particles have been used to better understand the primary processes in radiation chemistry. The yield of a chemical dosimeter (the Fricke dosimeter) and those of the hydrogen peroxide have been determined for different LET. The effect of the dose rate on the Fricke dosimeter yield and on the H{sub 2}O{sub 2} yield has been studied too. When the dose rate increases, an increase of the molecular products yield is observed. At very high dose rate, this yield decreases on account of the attack of the molecular products by radicals. The H{sub 2}O{sub 2} yield in alkaline medium decreases when the pH reaches 12. This decrease can be explained by a slowing down of the H{sub 2}O{sub 2} formation velocity in alkaline medium. Superoxide radical has also been studied in this work. A new detection method: the time-resolved chemiluminescence has been perfected for this radical. This technique is more sensitive than the absorption spectroscopy. Experiments with heavy ions have allowed to determine the O{sub 2}{sup .-} yield directly in the irradiation cell. The experimental results have been compared with those obtained with a Monte Carlo simulation code. (O.M.)

    Full Text Available Objective: to understand the strategies used by nursing technicians in order to face the occupational suffering in an emergency room. Methods: qualitative study carried out in an emergency room of a high complexity hospital located in the north of Paraná state. Data were collected through semi-structured interviews with 12 nursing technicians. The analysis relied on content analysis procedures. Results: respondents revealed as individual strategies to face suffering: try not to get involved with the patient; separation between professional and personal life; and spirituality/religion as support for coping. The collective strategies described by respondents included: action planning for unexpected events in this unit; creating a supportive environment; and attempt to obtain recognition of headship. Conclusion: individual and collective strategies were used consciously by workers and should be encouraged by managers to face the occupational suffering.

    2001-11-16

    Solvents, glues, spray paints, coatings, silicones, and other products contain normal (n-) hexane, a petroleum distillate and simple aliphatic hydrocarbon. n-Hexane is an isomer of hexane and was identified as a peripheral neurotoxin in 1964. Since then, many cases of n-hexane-related neurotoxicity have occurred in printing plants, sandal shops, and furniture factories in Asia, Europe, and the United States. This report describes an investigation of n-hexane-associated peripheral neuropathy in an automotive technician, an occupation in which this condition has not been reported, and summarizes the results of two other case investigations in the automotive repair industry. The findings suggest that solvent manufacturers should avoid using hexane when producing automotive degreasing products, and automotive technicians should avoid regular contact with hexane-based cleaning solvents.

    2013-07-01

    Full Text Available The paper describes the mathematic self-tuition process for technicians training. Once a theoretical framework was built up, the process of self-tuition in mathematics was modeled and introduced at experimental scale. The structure of the process is fully described together with the connections between subsystems and components. The methods and procedures of self-tuition are also described. The guiding principle is that designing a mathematic self-tuition process requires didactic procedures illustrating how professional technical problems may be contextualized for planning, organizing, performing and controlling the study of mathematics. The feasibility appraisal of the model proved that it favors the learning technical contents under the basis of strengthening a mathematic culture. Key words: self-tuition process, technicians´ training, self-control

    Full text: As in other countries, life expectancy is increasing in Brazil, and the number of radiological examinations tends to increase. Old equipment and high technology ones cohabit, radiology technicians are not well prepared to conduct practices, images and doses to patients are not optimized. Digital techniques that began to be introduced in the last years are also an important issue, because, as it is possible to modify the image digitally, there is less concern about the choice of equipment parameters that produce the best-image/lowest-dose compromise. Pediatric radiology, CT and fluoroscopy require attention too, as they are of dosimetric interest or because the patient ages imply higher risks or because the techniques deliver higher doses than the conventional ones. In our opinion, the most important role that we can play is educating and forming people to work in this area: training programs and refreshing courses are a way of facing the problem. This way, we are organizing, in a technical cooperation with IAEA, two training courses in quality assurance and radiation protection in radiology, one designed to physicists (60 h), and the radiological technicians (40 h). An important cooperation with a paediatric and a general hospital made it possible to offer courses with 50% practical lessons, performed both in the University and in hospital equipment. Both courses cover a basic Radiation Physics program, radiation protection, image formation and quality control in conventional and digital equipment, and patient dosimetry. Equipment donated by IAEA facilitate the practical QA and dosimetry lessons. The rationale of our project is making it sustainable through the formation of physicists that will go on in the education process of technicians in technical schools. We present the results of the first two courses (physicists and technicians), considering the selection process, the development of the activities, and the assessment both of the students enrolled

    Internationally there is an increasing focus on the clinical and cognitive services that pharmacists can provide. Lack of time has been identified as a barrier to pharmacists increasing their clinical activities. Within the pharmacy workplace there are many tasks that can only be performed by a pharmacist. The final accuracy check of a dispensed prescription is currently the sole responsibility of pharmacists in New Zealand. This takes up a significant amount of time during a pharmacist's work day. The introduction of a checking technician role has been suggested to allow pharmacists more time to do more patient focused work. To investigate the amount of time pharmacy staff spend on specific activities and to establish whether the introduction of a checking technician into twelve pilot sites increased the amount of time that the pharmacists could spend on patient focused activities. This study utilised a self-reported work sampling technique in twelve pilot sites, selected from both the hospital and community settings. Work sampling using an electronic device was conducted at two time-points (before the implementation of a Pharmacy Accuracy Checking Technician (PACT) role and when the PACT was in place). Data was collected at 10 min intervals for the period of five days, a working week. Tasks were grouped into patient focused, dispensing and personal activities. The introduction of the PACT into the pilot sites saw a mean increase of 19% in pharmacists' patient focused activities and a mean 20% decrease in dispensing activities. The introduction of a checking technician role into New Zealand pharmacies demonstrated the potential to provide pharmacists with more time to spend on patient focused activities. Copyright © 2017.

    Brian F Gage

    2011-05-01

    Full Text Available Introduction: The objective of this study was to evaluate emergency medicine physician and nurse acceptance of nonnurse, nonphysician screening for geriatric syndromes. Methods: This was a single-center emergency department (ED survey of physicians and nurses after an 8-month project. Geriatric technicians were paid medical student research assistants evaluating consenting ED patients older than 65 years for cognitive dysfunction, fall risk, or functional decline. The primary objective of this anonymous survey was to evaluate ED nurse and physician perceptions about the geriatric screener feasibility and barriers to implementation. In addition, as a secondary objective, respondents reported ongoing geriatric screening efforts independent of the research screeners. Results: The survey was completed by 72% of physicians and 33% of nurses. Most nurses and physicians identified geriatric technicians as beneficial to patients without impeding ED throughput. Fewer than 25% of physicians routinely screen for any geriatric syndromes. Nurses evaluated for fall risk significantly more often than physicians, but no other significant differences were noted in ongoing screening efforts. Conclusion: Dedicated geriatric technicians are perceived by nurses and physicians as beneficial to patients with the potential to improve patient safety and clinical outcomes. Most nurses and physicians are not currently screening for any geriatric syndromes. [West J Emerg Med. 2011;12(4:489–495.

    PurposeThe purpose of this study is to describe the outcomes of a technician-delivered glaucoma referral triaging service with 'virtual review' of resultant data by a consultant ophthalmologist.Patients and methodsThe Glaucoma Screening Clinic reviewed new optometrist or GP-initiated glaucoma suspect referrals into a specialist ophthalmic hospital. Patients underwent testing by three ophthalmic technicians in a dedicated clinical facility. Data were reviewed at a different time and date by a consultant glaucoma ophthalmologist. Approximately 10% of discharged patients were reviewed in a face-to-face consultant-led clinic to examine the false-negative rate of the service.ResultsBetween 1 March 2014 and 31 March 2016, 1380 patients were seen in the clinic. The number of patients discharged following consultant virtual review was 855 (62%). The positive predictive value of onward referrals was 84%. Three of the 82 patients brought back for face-to-face review were deemed to require treatment, equating to negative predictive value of 96%.ConclusionsOur technician-delivered glaucoma referral triaging clinic incorporates consultant 'virtual review' to provide a service model that significantly reduces the number of onward referrals into the glaucoma outpatient department. This model may be an alternative to departments where there are difficulties in implementing optometrist-led community-based referral refinement schemes.

    1976-01-01

    The γ radiolysis of ethyl bromide has been investigated at 100 Torr pressure and 23 0 C. In the pure system between an absorbed dose of 1.0 x 10 20 and 1.5 x 10 20 eV/g the major products and their respective G values are as follows: hydrogen bromide, 3.89; ethane, 2.70; ethylene, 2.17; acetylene, 0.31; hydrogen, 1.39; 1,1-dibromoethane, 0.88; 1,2-dibromoethane, 0.12; vinyl bromide, 0.32; methane, 0.083; methyl bromide, 0.080; and bromoform, 0.0078. When oxygen is added, the G values in this dose range become the following: hydrogen bromide, 4.89; ethane, 0.31; ethylene, 0.78; acetylene, 0.27; hydrogen, 1.38; 1,1-dibromoethane, 0.028; 1,2-dibromoethane, 0.56; vinyl bromide, 0.0; methane 0.03; methyl bromide, 0.32; and bromoform, 0.0034. Bromine is also formed with a G value of 2.4 when oxygen is added. The presence of hydrogen and acetylene in the radiolysis indicates that these species must be formed from higher energy processes not accessible in the 253.7-nm photolysis, which was studied in a parallel investigation. The product distribution indicates that the probabilities of single bond rupture in the primary event are approximately C 2 H 5 --Br:C 2 H 4 Br--H:CH 3 --CH 2 Br = 1.00:0.40:0.06. Either a hot hydrogen atom abstraction reaction or direct molecular H 2 elimination accounts for about 16 percent of the hydrogen yield. Strong similarities in dose-yield plots suggest that many of the secondary processes involved in the photolysis are important in the radiolysis of ethyl bromide as well. The high pressure mass spectrometry of the system indicates the role of ionic species. Differences in radiolytic behavior of ethyl chloride, bromide, and iodide can largely be explained in terms of the energetics of the primary and secondary processes in each system

    1977-01-01

    Work on calibrating the radiation intensity in our γ-ray source as a function of height and horizontal displacement was completed. For extended chain (high crystallinity) polyethylene (PE) before and after quenching from the melt irradiated at room temperature, the crosslinking yield increased twofold on lowering the crystallinity from 96 to 70%. The G-value for alkyl radical production was about 75% higher in the quenched extended chain sample as compared to the value before quenching. The G (alkyl) values were determined for irradiations at 77K. The rate of decay of the alkyl radicals in PE samples of single crystals having different stem lengths was studied at 80 and 85 0 . It was found that the mole fraction of the slowly decaying free radicals increased with the stem length. Hydrogen gas was found to catalyze both the slow and fast decays. Because hydrogen does not dissolve in the crystalline regions of the PE, the catalytic effect must occur at the amorphous boundary of the crystalline stems. With respect to the kinetics of the allyl radical, either it was found that the data could be explained in terms of two simultaneous but spatially separated second order reactions. As the temperature is raised to 135 0 , the two reactions merge into one. Hydrogen gas has no effect on the decay of the allyl radicals. In the case of the highly crystalline extended chain samples, the allyl decay in some cases follows the simple kinetic equation (1/c) - (1/c 0 ) = k√t, where k is called a time independent diffusion controlled reaction rate constant. The less the crystallinity of the sample the greater the k constant. A preliminary study of isotactic polypropylene (PP) was carried out and a definite hydrogen gas catalysis of the free radical decay in PP was seen. Similarly in crystalline 1-leucine the hydrogen catalytic effect could also be clearly demonstrated

  7. Radiation chemistry in exploration of Mars

    Zagorski, Z.P.

    2005-01-01

    Problems of exploration of Mars are seldom connected with radiation research. Improvements in such approach, more and more visible, are reported in this paper, written by the present author working on prebiotic chemistry and origins of life on Earth. Objects on Mars subjected to radiation are very different from those on Earth. Density of the Martian atmosphere is by two orders smaller than over Earth and does not protect the surface of Mars from ionizing radiations, contrary to the case of Earth, shielded by the equivalent of ca. 3 meters of concrete. High energy protons from the Sun are diverted magnetically around Earth, and Mars is deprived of that protection. The radiolysis of martian '' air '' (95.3% of carbon dioxide) starts with the formation of CO 2 + , whereas the primary product over Earth is N 2 + ion radical. The lack of water vapor over Mars prevents the formation of many secondary products. The important feature of Martian regolith is the possibility of the presence of hydrated minerals, which could have been formed milliards years ago, when (probably) water was present on Mars. The interface of the atmosphere and the regolith can be the site of many chemical reactions, induced also by intensive UV, which includes part of the vacuum UV. Minerals like sodalite, discovered on Mars can contribute as reagents in many reactions. Conclusions are dedicated to questions of the live organisms connected with exploration of Mars; from microorganisms, comparatively resistant to ionizing radiation, to human beings, considered not to be fit to manned flight, survival on Mars and return to Earth. Pharmaceuticals proposed as radiobiological protection cannot improve the situation. Exploration over the distance of millions of kilometers performed successfully without presence of man, withstands more easily the presence of ionizing radiation. (author)

  8. Radiation Chemistry in Ammonia-Water Ices

    We studied the effects of 100 keV proton irradiation on films of ammonia-water mixtures between 20 and 120 K. Irradiation destroys ammonia, leading to the formation and trapping of H2, N2 NO, and N2O, the formation of cavities containing radiolytic gases, and ejection of molecules by sputtering. Using infrared spectroscopy, we show that at all temperatures the destruction of ammonia is substantial, but at higher temperatures (120 K), it is nearly complete (approximately 97% destroyed) after a fluence of 10(exp 16) ions per square centimeter. Using mass spectroscopy and microbalance gravimetry, we measure the sputtering yield of our sample and the main components of the sputtered flux. We find that the sputtering yield depends on fluence. At low temperatures, the yield is very low initially and increases quadratically with fluence, while at 120 K the yield is constant and higher initially. The increase in the sputtering yield with fluence is explained by the formation and trapping of the ammonia decay products, N2 and H2 which are seen to be ejected from the ice at all temperatures.

    The structural changes throughout the entire reductive radiation-induced pathway of l-α-alanine are solved on an atomistic level with the aid of periodic DFT and nudged elastic band (NEB) simulations. This yields unprecedented information on the conformational changes taking place, including the protonation state of the carboxyl group in the "unstable" and "stable" alanine radicals and the internal transformation converting these two radical variants at temperatures above 220 K. The structures of all stable radicals were verified by calculating EPR properties and comparing those with experimental data. The variation of the energy throughout the full radiochemical process provides crucial insight into the reason why these structural changes and rearrangements occur. Starting from electron capture, the excess electron quickly localizes on the carbon of a carboxyl group, which pyramidalizes and receives a proton from the amino group of a neighboring alanine molecule, forming a first stable radical species (up to 150 K). In the temperature interval 150-220 K, this radical deaminates and deprotonates at the carboxyl group, the detached amino group undergoes inversion and its methyl group sustains an internal rotation. This yields the so-called "unstable alanine radical". Above 220 K, triggered by the attachment of an additional proton on the detached amino group, the radical then undergoes an internal rotation in the reverse direction, giving rise to the "stable alanine radical", which is the final stage in the reductive radiation-induced decay of alanine.

  12. Study of catalytic phenomena in radiation chemistry

    Two phenomena have been studied: the action of γ rays from radio-cobalt on the adsorption and catalytic properties of ZnO and NiO in. relationship with the heterogeneous oxidation of CO, and the homogeneous catalysis by OsO 4 of the oxidation of various aqueous phase solutes by the same radiation. The prior irradiation of ZnO and of NiO does not modify their catalytic activity but generally increases the adsorption energy of -the gases CO and O 2 . The influence of the radiations appears to be connected with the presence of traces of water on ZnO and of an excess of oxygen on NiO. Osmium tetroxide which is not degraded by irradiation in acid solution, accelerates the radiolytic oxidation of certain compounds (Te IV , Pt 11 , As 111 ) in the presence of oxygen, as a result of its sensitizing effect on the oxidation by H 2 O 2 . In the case of phosphites on the other hand, OsO 4 has a protecting action under certain conditions of acidity and may suppress entirely the chain reaction which characterizes the oxidation of this solute byγ rays. A general mechanism is proposed for these phenomena. The rate constant for the OsO 4 + HO 2 reaction is calculated to be 5.7 x 10 5 l.mol -1 . sec -1 . (author) [fr

    Oxygen-free aqueous solutions of 0.1 M NH 2 CN (pH 2.4 and 5) were irradiated with γ rays (0.01--25 Mrad). The rate constants determined in competition experiments are: k(H + NH 2 CN) = 6.7 x 10 6 M -1 sec -1 , k(e/sub aq/ - + NH 2 CN) = 1.5 x 10 9 M -1 sec -1 , and k(OH + NH 2 CN) = 8.5 x 10 6 M -1 sec -1 . Radiation-chemical yields were determined for the decomposition of cyanamide molecules and the formation of several radiolytic products. The following compounds were identified in irradiated solutions: H 2 , CO 2 , NH 3 , urea, biuret, arginine, and a--N=N-- molecule assigned to methylaminoazoformamide. Possible reactions of secondary free radicals leading to the formation of radiolytic products were considered by taking into account the model of water radiolysis and the measured radiation yields

    Adrenalin has been studied as a model radiation protective agent by means of pulse radiolysis in aqueous solutions. The rate constants for the reactions of adrenalin with e - sub(aq) and OH were determined: k(e - sub(aq) + adr -NH + 2 ) = 7.5 x 10 8 dm 3 mol -1 s -1 , k(e - sub(aq) + adr - NH) = 2.5 x 10 8 dm 3 mol -1 s -1 , and k(OH + adr) = 2.2 x 10 -10 dm 3 mol -1 s -1 (pH = 9.2). e - sub(aq) attacks the amino group by splitting off methylamine, whereas OH and O - sub(aq) lead to the formation of the corresponding adducts of the cyclohexadienyl type. OH radicals can also abstract an electron from an 0 - group at pH > 8. (author)

    The effect of the concentrate of liquor made from dried sweet potato on the proliferation of tetrahymena pyriformis has been studied. The toxicity of d-2,3-butanediol and ethanol have also been investigated by the tetrahymena pyriformis and it has been found that they did not produce the effect on the propagation of the cell up to 250 and 1000 ppm, separately. The unirradiated concentrate of the different batch liquors all appear more or less inhibition on the proliferation of tetrahymena pyriformis. The effect is more remarkable for the concentrate of the irradiated liquors and is strengthened as increase of adsorbed dose. It shows that the toxicity of the concentrate of the irradiated liquor to tetrahymena pyriformis may be related to the quality of the dried sweet potato used and the formation of radiolytic products with higher boiling point

    Effective communication and cooperation between dentists and dental technicians are essential in providing quality services. There has been a lack of information regarding dentist-dental technician communications and current methods and materials used for the fabrication of fixed partial dentures (FPDs). This cross-sectional study identified the materials and techniques used for fabrication of FPDs, as well as the status of communication between dentists and dental technicians in Thessaloniki, Greece. A questionnaire was developed with 7 sections pertaining to procedures and materials used for the fabrication of fixed prostheses: general questions, infection control, impressions/interocclusal records, die technique/mounting, information from final casts, prostheses design/materials, and communication/shade selection. The questionnaire was anonymous and distributed by the Association of Dental Technicians of Thessaloniki to all member laboratories (228) in the wider province of Thessaloniki, Greece. Due to the absence of normal distribution of the results, frequencies and medians were reported. Ninety-six of 228 dental laboratories responded (42.1% response rate). Twenty-six percent of dental laboratories did not routinely disinfect incoming items. The dental technicians considered 30% of incoming final impressions and 20% of interocclusal registrations as inadequate. Half of the time (55%) final casts were mounted by technicians on simple hinge articulators. Only 20% of tooth preparations had adequate finish lines. The majority (70%) of fixed restorations were metal-ceramic. Fifty-seven percent of dental technicians considered the delivery time requested by dentists as insufficient. The information provided in this study indicates areas of weakness in communication between dentists and dental technicians, along with areas where both parties should use greater care during clinical and laboratory procedures.

    The efficacy of radiation therapy is to eradicate the tumor while preserving the integrity of normal tissues. Technological advances have allowed to develop techniques capable of modulating doses delivered to the target volume, providing more effective treatments. However, the operational complexity of these techniques makes the benefits offered are directly proportional to the chances of occurrences of serious errors. The objective of this work is to analyze the steps performed by the technician/technologist in Intensity Modulated Radiotherapy (IMRT), to detect possible errors in order to determine ways to mitigate them. After literature regarding errors in the radiation therapy, a prospective analysis was performed in the first half of 2012 in a radiation clinic located in the city of Rio de Janeiro, in which 11 technicians/technologists contributed to the survey data analysis. The method of risk analysis Failure Mode and Effects Analysis was used for prospective analysis of accidents/incidents, with respect to a qualitative assessment . The method allowed mapping 16 steps performed by technicians/technologists in the treatments with IMRT, identifying possible failures and their causes allowing to find ways to avoid possible errors. This analysis helped to confirm that the qualification and continuing education of technicians/technologists, allied to implement quality assurance programs and a computerized management can make a tool capable of IMRT to achieve the greatest challenge of radiotherapy.

  5. Royal Engineer Geographic Technicians: Exploring their attitudes to education and training

    Science.gov (United States)

    Knight, John Anthony

    A creative approach is presented for understanding the attitudes of Royal Engineer (RE) Geographic Technicians (Geo Techs) to training and education. Through a grounded theory methodology, participants' experiences of learning and teaching are explored. These provide a greater awareness and perception of attitudes than have emerged through more established, formal methods of evaluating the effectiveness of training. Recent developments in technology, doctrine, requirements and operations have brought about significant changes to the range and complexity of subjects taught in the field of Geospatial Intelligence (GEOINT). This in turn has increased the challenges to RE staff and students, many of whom find themselves instructing on or undertaking demanding degree level courses without the requisite formal qualifications. Grounded theory, based on guidelines rather than rigid rules, is adopted to provide a study of RE Geographic Technicians' learning experiences from the perspective of those who live it and for an interpretive understanding of their meanings to emerge. The policies, culture and social processes in which the RE Geo training takes place are explored to appreciate the influence of the training environment on learning. Data obtained through focus groups held with students and instructors, and through in-depth interviews with individuals who hold key roles associated with the course, recognises the relativism of multiple social realities in developing a rich source of knowledge on attitudes to learning. The collection, synthesis and analysis of data led to the emergence of core categories: context, commitment, expectations, motivation, qualifications, relevance and respect. Through their engagement the research participants' awareness, in particular of instructors, of Geographic Technicians' attitudes to training and education has been raised. Using the theoretical framework of communities of practice, the challenges and effectiveness of the RSMS as a

    This paper deals with an application of fuzzy numbers to the interaction between the written procedure and the technician during inspection. The techniques based on fuzzy set theory are appropriate tools for the treatment of subjective and vague concepts that are inherent to system reliability. The application consists of an analysis through fuzzy probability and through a failure possibility concept, which is a subjective unreliability measure. This approach allows the use of natural language expressions of reliability estimation. It is shown which events (human actions) should be focused on during training and practice in order to improve the above mentioned interaction. (author)

    Results of a survey assessing trends and innovations in the use of pharmacy technicians and other nonpharmacist staff in the research pharmacy setting are reported. A Web-based survey was distributed to Internet communities of members of the American Society of Health-System Pharmacists and the University Health-System Consortium involved in investigational drug research and related practice areas. The survey collected data on the characteristics of institutions with pharmacy department staff dedicated to such research activities and the participation of pharmacists, technicians, and other staff in key areas of research pharmacy operations. Survey responses from 51 institutions were included in the data analysis. Overall, the reported distribution of assigned responsibility for most evaluated research pharmacy tasks reflected traditional divisions of pharmacist and technician duties, with technicians performing tasks subject to a pharmacist check or pharmacists completing tasks alone. However, some institutions reported allowing technicians to perform a number of key tasks without direct pharmacist supervision, primarily in the areas of inventory management and sponsor monitoring and auditing; almost half of the surveyed institutions reported technician involvement in teaching activities. In general, the reported use of "tech-check-tech" arrangements in research pharmacies was very limited. Some responding institutions reported the innovative use of nonpharmacist staff (e.g., paid interns, students and residents on rotation). Although the majority of research pharmacy tasks related to direct patient care are performed by or under the direct supervision of pharmacists, a variety of other essential tasks are typically assigned to pharmacy technicians and other nonpharmacist staff.

    This study reports on factors that limit the participation of blind and partially sighted learners in mathematics and science education. Since the teacher, still remains one of the most crucial factors in any education system, the researcher deemed it important to investigate the role of the teacher as understood by a blind technician in promoting the participation of blind and partially sighted learners in mathematics and science subjects, which few of these learners take beyond primary school. A case study was conducted interrogating a blind technician, who regards himself as an unqualified scientist, in his understanding of various school factors that could entice blind and partially sighted learners to participate in mathematics and science education, and to promote their retention in related professions. The participant thus drew from his own experiences of the school environment and wider concentric social institutions. A semi-structured interview schedule was followed and the responses were recorded by mutual consent. Analysis was conducted based on questions put to the participant. The study revealed that teacher motivation and mentorship in mathematics and science methodologies and the use of tools for learner empowerment are lacking. It further revealed that teachers lack the requisite skills in special education to harness learner potential in mathematics and science. This situation necessitates government action in teacher training and development.

    Anaesthetic technicians play a key role in the operating room, yet little is known about their levels of job satisfaction or workplace stress. A blinded, confidential single mail-out survey was posted to anaesthetic technicians in New Zealand. The survey consisted of demographic information, a job satisfaction survey, the Maslach Burnout Inventory and the Short Form 12. At total of 154 forms were returned (51% response rate). Respondents worked predominantly in public hospitals and many had duties outside the operating room. Job satisfaction was related to teamwork, practical nature of work and patient contact, while dissatisfaction was related to lack of respect from nurses and limited career pathway. High to moderate levels of emotional exhaustion (48%), depersonalisation (39%) and low levels of personal accomplishment (58%) were indicators of burnout. The Short Form 12 revealed high levels of physical impairment in 24% and emotional impairment in 35% of respondents. These data suggest that work is needed to evaluate anaesthetic assistants' job structure and actively manage their important physical and emotional sequelae.

  13. Student reactions to problem-based learning in photonics technician education

    2014-07-01

    Problem-based learning (PBL) is an instructional approach in which students learn problem-solving and teamwork skills by collaboratively solving complex real-world problems. Research shows that PBL improves student knowledge and retention, motivation, problem-solving skills, and the ability to skillfully apply knowledge in new and novel situations. One of the challenges faced by students accustomed to traditional didactic methods, however, is acclimating to the PBL process in which problem parameters are often ill-defined and ambiguous, often leading to frustration and disengagement with the learning process. To address this problem, the New England Board of Higher Education (NEBHE), funded by the National Science Foundation Advanced Technological Education (NSF-ATE) program, has created and field tested a comprehensive series of industry-based multimedia PBL "Challenges" designed to scaffold the development of students' problem solving and critical thinking skills. In this paper, we present the results of a pilot study conducted to examine student reactions to the PBL Challenges in photonics technician education. During the fall 2012 semester, students (n=12) in two associate degree level photonics courses engaged in PBL using the PBL Challenges. Qualitative and quantitative methods were used to assess student motivation, self-efficacy, critical thinking, metacognitive self-regulation, and peer learning using selected scales from the Motivated Strategies for Learning Questionnaire (MSLQ). Results showed positive gains in all variables. Follow-up focus group interviews yielded positive themes supporting the effectiveness of PBL in developing the knowledge, skills and attitudes of photonics technicians.

    The challenges of health care are increasingly complex and subject to frequent change. Meeting these demands requires that health professionals work in partnership with each other and the patient. One way of contributing to this is for students to learn together. However, effective teamwork requires an education system that helps to foster understanding among all those entering the health workforce. The purpose of this study was to investigate the attitudes towards shared learning of undergraduate dental students and trainee dental technicians in a university dental school/hospital in the United Kingdom. Twenty-five trainee dental technicians and 75 undergraduate dental students took part in the study over five academic years. Data were collected using structured questionnaires. A 100% response rate was achieved from the questionnaires. The results indicated the majority of students recognized the benefits of shared learning and viewed the acquisition of teamworking skills as useful for their future working lives, beneficial to the care of their patients, and likely to enhance professional working relationships. The study also found a positive association of being valued as an individual in the dental team by all student groups. Future dental curricula should provide opportunities to develop effective communication between these two groups and encourage teamworking opportunities. These opportunities need to be systematically developed in the dental curriculum to achieve the desired goals.

    Assessment of a multisite rural teledermatology project between 2009 and 2012 in four Pacific Northwest states that trained primary care providers and imaging technicians in state-of-the-art techniques of telemedicine. In 2012, we assessed provider and imaging technician acceptability and satisfaction with a 32-item survey instrument based on the Patient Satisfaction Questionnaire developed by Ware et al. (Eval Program Plann 1983;6:247-63) and modified for telemedicine by Kraai et al. (J Card Fail 2011;17:684-690). Survey questions covered eight satisfaction domains: interpersonal manner, technical quality, accessibility, finances, efficacy, continuity, physical environment, and availability. Overall, 71% of the primary care providers and 94% of the imaging technicians reported being satisfied or extremely satisfied with the teledermatology project. Most (95%) providers found the continuing education classes on dermatology diagnosis and treatment topics useful, and 86% reported teledermatology was a good addition to regular patient services. Most (97%) of the imaging technicians were satisfied with the ability of teledermatology to improve the description of dermatology conditions using images of the lesions or rashes, and 91% were satisfied with the convenience of teledermatology. Challenges reported by both providers and imaging technicians include an increase in workload due to more patient visits related to dermatology care and limited information technology support. Given the Veterans Health Administration's initiatives to promote accessible health care to underserved Veterans using telehealth, these findings can inform future program designs for teledermatology.

    2012-12-01

    Nuclear medicine technicians work daily with radioactive isotopes, and therefore receive a certain amount of radiation dose. The aim of this study was to assess the radiation dose, during various tasks, to the technicians at four nuclear medicine departments and to investigate to what extent there are differences between the departments and possible reasons for such. Measurements were made at nuclear medicine departments at four Norwegian hospitals. Doses to the technicians were measured with an educational direct dosimeter-instrument worn outside the lead apron during work at hot-lab, administrating the injection and image acquisition. Calculated annual collective and individual doses were compared with data from personal dosimetry. A value of ∼1 nSv MBq(-1) seems to be representative for modern Norwegian nuclear medicine departments. In departments with upgraded hot-labs, the largest dose contribution is received during image acquisition.

    Pharmacy technicians are expanding their scope of practice, often in partnership with pharmacists. In oncology, such a shift in responsibilities may lead to workflow efficiencies, but may also cause concerns about patient risk and medication errors. The primary objective was to compare the time spent on order entry and order-entry checking before and after training of a clinical support pharmacy technician (CSPT) to perform chemotherapy order entry. The secondary objectives were to document workflow interruptions and to assess medication errors. This before-and-after observational study investigated chemotherapy order entry for ambulatory oncology patients. Order entry was performed by pharmacists before the process change (phase 1) and by 1 CSPT after the change (phase 2); order-entry checking was performed by a pharmacist during both phases. The tasks were timed by an independent observer using a personal digital assistant. A convenience sample of 125 orders was targeted for each phase. Data were exported to Microsoft Excel software, and timing differences for each task were tested with an unpaired t test. Totals of 143 and 128 individual orders were timed for order entry during phase 1 (pharmacist) and phase 2 (CSPT), respectively. The mean total time to perform order entry was greater during phase 1 (1:37 min versus 1:20 min; p = 0.044). Totals of 144 and 122 individual orders were timed for order-entry checking (by a pharmacist) in phases 1 and 2, respectively, and there was no difference in mean total time for order-entry checking (1:21 min versus 1:20 min; p = 0.69). There were 33 interruptions not related to order entry (totalling 39:38 min) during phase 1 and 25 interruptions (totalling 30:08 min) during phase 2. Three errors were observed during order entry in phase 1 and one error during order-entry checking in phase 2; the errors were rated as having no effect on patient care. Chemotherapy order entry by a trained CSPT appeared to be just as safe and

    Introduction: In our region Advanced Emergency Medical Technicians (AEMTs) respond to acutely ill or injured patients in rural areas. The AEMTs have been authorized to administer fentanyl intravenously in doses up to 2 μg/kg to selected groups of patients in pain. Higher doses can be allowed...... by a physician after a teleconference. We examined the effect of intravenous (IV) fentanyl treatment, expressed as pain reduction on a 10-point Numeric Rating Scale (NRS). Moreover we examined the occurrence of negative coincident events to assess whether it was safe to let non-medical staff administer potent...... opioids intravenously.   Methods: Retrospectively we collected the case sheets for all patients treated with IV fentanyl by the AEMTs in 2005 and 2006. We excluded all patients where a physician had been directly involved in the prehospital treatment. We recorded the IV fentanyl dose, NRS-score before...

    Full Text Available The present study aims at analyzing the motivations of students in a nurse technician course for working in the health field. It is an exploratory study conducted with 18 students at a high school institution, through an open-ended questionnaire about their motivations for working in the field. The data were analyzed using the thematic analysis technique. The interviewees indicate that their motivation for such work is due to the feeling of accomplishment and professional responsibility, as well as external incentives. On the other hand, they point to the lack of options for reaching higher professional levels and the personal fatigue of being exposed to suffering. Thus, they experience both suffering and pleasure. Based on these findings, it is important to adopt measures to incentivize their professional development and improve working conditions. doi: 10.5216/ree.v16i2.20827.

  7. From the "Technician Thing" to the "Mental Game": Masculinity and U.S. Homebirth.

    Science.gov (United States)

    Driesslein, April

    2017-12-01

    Previous research on pregnancy and birth from the perspective of men has found that men approach them from the perspective of hegemonic masculinity, though many find that hospital birth is a time of potential failure at masculinity. In this qualitative study of 11 men who had children born at home, I find that, like their hospital-birth counterparts, they find roles in their partners' pregnancies and early labors that are congruent with hegemonic masculinity. In ways that converge and diverge with the experience of hospital-birth fathers, they find their masculinity disrupted as the birth approaches, becoming nurturers and servers rather than technicians and protectors. These acts shift them from the masculinity of a young man to that of a father. This is consonant with Connell's (1995) theory that masculinity is not singular, but shifts situationally and across the life course, and Butler's (2003) theory that gender is constructed through acts. © 2017 by the American Anthropological Association.

    Doede, S.

    1999-07-01

    Approximately one year ago, OSU-Okmulgee and the Gas Processors Association began discussions about the possibility of developing a natural Gas Technician Training Program for GPA members. Following a presentation to the Membership and Services Committee, Chairman John Ehlers solicited and obtained the approval of the GPA Executive Committee to sponsor the program. Participation in the program was also made available to GPSA members. The purpose of the program is to upgrade the technical competency and professional level of incoming natural gas compression technicians. It educates students to analytically diagnose, service and maintain gas compression equipment and systems using industry recommended procedures, special tools and service information. It also provides course content, which will enable successful graduates to advance in position after additional experience, and to understand new systems, technologies and components as they are introduced. The two-year Associate-In-Applied Science Degree program includes six successive college semesters. Nearly one-half of the time is designated for technical/academic education at Oklahoma State University-Okmulgee with the balance of time allocated for on-the-job internship experiences at sponsoring GPA/GPSA members. Each block of technical education and general education course work is followed by an immediate work experience time period designated to reinforce the technical and general education. These time periods are approximately seven and one-half weeks in length each. It is essential for the success of the students and the program that the students' education at OSU-Okmulgee and work experiences at GPA/GPSA member facilities be closely aligned for maximum student learning and retention. In addition to technical classes on gas compression equipment and components, the courses offered in math, speech, technical writing, psychology and ethics for example, prepare students to be able to communicate well, get

    Huerkamp, Michael J

    2006-09-01

    To understand and better manage attendance and overtime for a team of veterinary technicians, a retrospective analysis of the attendance and time card records was done over a 2-y period. The findings show that veterinary technicians were in the workplace for a combination of straight time and overtime hours for approximately 89% of all compensated hours. The remainder of paid compensation was for vacation (4%), holidays (4%), and sick leave (3%). This team of veterinary technicians earned significantly more overtime hours, as much as 9% of total annual compensated hours, than the reported 3% standard for animal resources programs nationwide. The majority of overtime hours (61%) were for assigned weekend and holiday duty and after-hours veterinary medical emergencies. Veterinary technicians expended sick leave at 75% of the amount accrued and at a statistically significantly rate 65% higher than the national average for unscheduled absences for hourly personnel in animal resources programs. Because the direct cost of absenteeism may exceed 645 dollars per employee annually and because work inappropriately done at premium pay outside of business hours is a controllable expense, sound management of attendance and overtime is important in cost containment for animal resources programs.

    Do people move to cities because of marriage market considerations? In cities singles can meet more potential partners than in rural areas. Singles are therefore prepared to pay a premium in terms of higher housing prices. Once married, the marriage market benefits disappear while the housing...... premium remains. We extend the model of Burdett and Coles (1997) with a distinction between efficient (cities) and less efficient (non-cities) search markets. One implication of the model is that singles are more likely to move from rural areas to cities while married couples are more likely to make...

    Huss, Anke; Schaap, Kristel; Kromhout, Hans

    2017-07-01

    Imaging technicians working with magnetic resonance imaging (MRI) may experience acute effects such as vertigo or dizziness when being exposed. A previous study also reported an increased risk of accidents in MRI exposed staff. We aimed at evaluating commuting accident risk in Dutch imaging technicians. Of invited imaging technicians, 490 (29%) filled in a questionnaire pertaining to (near) accidents when driving or riding a bike, health, lifestyle and work practices. We used logistic regression to evaluate the association between exposure to MRI-related electromagnetic fields and risk of commuting (near) accidents in the year prior to the survey, adjusted for a range of potential confounders. Our cross-sectional study indicated an increased risk of (near) accidents if imaging technicians had worked with MRI in the year prior to the survey (odds ratio OR 2.13, 95%CI 1.23-3.69). Risks were higher in persons who worked with MRI more often (OR 2.32, 95%CI 1.25-4.31) compared to persons who worked sometimes with MRI (OR 1.91, 95%CI 0.98-3.72), and higher in those who had likely experienced higher peak exposures to static and time-varying magnetic fields (OR 2.18, 95%CI 1.06-4.48). The effect was seen on commuting accidents that had occurred on the commute from home to work as well as accidents from work to home or elsewhere. Imaging technicians working with MRI scanners may be at an increased risk of commuting (near) accidents. This result needs confirmation and potential risks for other groups (volunteers, patients) should be investigated. Copyright © 2017 Elsevier Inc. All rights reserved.

    2017-12-16

    In Great Britain (GB), pharmacy technicians (PTs) are registered professionals, with their education and training regulated; little is known about this or the learning environment in which it takes place. This study aimed to profile recently registered pre-registration trainee pharmacy technicians (PTPTs) in GB and capture views on PTPTs' training experiences, focussing on differences in community and hospital settings. A mixed methods study was conducted in 2013-14, following university ethics approval. One-to-one, semi-structured telephone interviews with face-to-face and distance education providers, and hospital and community pharmacy employers of PTPTs explored views on education delivery, work-based learning, and assessment. Interviews were transcribed verbatim, analysed thematically and findings informed design of a census survey of all 1457 recently registered PTs, investigating satisfaction with various aspects of their training. Quantitative data were analysed using SPSS v20, employing comparative statistics (Mann-Whitney U, Chi-Square). Six-hundred and forty-six questionnaires were returned (response rate 44.3%), 632 were usable. Three-quarters (75.9%) of respondents had trained in community; the majority (88.0%) were female, the average age was 35.26 ± 10.22. Those based in hospitals were more satisfied with their training: hospital trainees worked in larger teams and tended to be better supported, they had more study time, and were more likely to complete their training in the intended two-year period. Interviews with staff in 17 Further Education colleges, 6 distance providers, 16 community pharmacies and 15 NHS organisations confirmed survey findings and offered explanations into why differences in training experiences may exist. This study has identified differences between PTPTs' work-based experiences in hospital and community pharmacy. Perceiving PTPTs as 'apprentices' vs. 'employees' may define how their training is managed by employers

    Simulation-based education (SBE) has seen a dramatic uptake in health professions education over the last decade. SBE offers learning opportunities that are difficult to access by other methods. Competent faculty is seen as key to high quality SBE. In 2011, in response to a significant national healthcare issue--the need to enhance the quality and scale of SBE--a group of Australian universities was commissioned to develop a national training program--Australian Simulation Educator and Technician Training (AusSETT) Program. This paper reports the evaluation of this large-scale initiative. The AusSETT Program adopted a train-the-trainer model, which offered up to three days of workshops and between four and eight hours of e-learning. The Program was offered across all professions in all states and territories. Three hundred and three participants attended workshops with 230 also completing e-learning modules. Topics included: foundational learning theory; orientation to diverse simulation modalities; briefing; and debriefing. A layered objectives-oriented evaluation strategy was adopted with multiple stakeholders (participants, external experts), methods of data collection (end of module evaluations, workshop observer reports and individual interviews) and at multiple data points (immediate and two months later). Descriptive statistics were used to analyse numerical data while textual data (written comments and transcripts of interviews) underwent content or thematic analysis. For each module, between 45 and 254 participants completed evaluations. The content and educational methods were rated highly with items exceeding the pre-established standard. In written evaluations, participants identified strengths (e.g. high quality facilitation, breadth and depth of content) and areas for development (e.g. electronic portfolio, learning management system) of the Program. Interviews with participants suggested the Program had positively impacted their educational practices

    Full Text Available Progressive cities worldwide have demonstrated political leadership by initiating meaningful strategies and actions to tackle climate change. However, the lack of knowledge concerning embodied greenhouse gas (GHG emissions of cities has hampered effective mitigation. We analyse trans-boundary GHG emission transfers between five Australian cities and their trading partners, with embodied emission flows broken down into major economic sectors. We examine intercity carbon footprint (CF networks and disclose a hierarchy of responsibility for emissions between cities and regions. Allocations of emissions to households, businesses and government and the carbon efficiency of expenditure have been analysed to inform mitigation policies. Our findings indicate that final demand in the five largest cities in Australia accounts for more than half of the nation’s CF. City households are responsible for about two thirds of the cities’ CFs; the rest can be attributed to government and business consumption and investment. The city network flows highlight that over half of emissions embodied in imports (EEI to the five cities occur overseas. However, a hierarchy of GHG emissions reveals that overseas regions also outsource emissions to Australian cities such as Perth. We finally discuss the implications of our findings on carbon neutrality, low-carbon city concepts and strategies and allocation of subnational GHG responsibility.

    The associations between occupational irradiation, cigarette smoking, alcohol drinking and clinical examination data were investigated in Japanese male radiology technicians. The number of investigated examination items was 35, including 29 biochemical serum test, four hematological tests and systolic and diastolic blood pressure. The associations with each factor were evaluated using the multiple linear regression model. As single factors, radiation associated with urea nitrogen, alkaline phosphatase, monoamine oxidase and leukocyte count (four items), smoking associated with albumin-globulin index, zinc sulfate turbidity test, urea nitrogen, creatinine, neutral fat, amylase, serum iron, leukocyte count, hemoglobin and hematocrit (10 items), and drinking associated with creatinine, uric acid, glutamate oxaloacetate transaminase, leucine aminopeptidase, alkaline phosphatase and erythrocyte count (six items). As synergistic factors, the combination of radiation and smoking associated with nine items, radiation and drinking 10 items, smoking and drinking four items, and radiation, smoking and drinking two items. These results suggested that the number of items which radiation associated as single-factor were less than that of smoking and of drinking, however suggested that associations between radiation and examination data was synergistic when combined with smoking or drinking.

    The current study described RN and patient care technician (PCT) communication in centralized and hybrid decentralized workstation designs using hands-free communication technology and infrared locator badge technology to facilitate communication. New construction of an oncology unit provided the opportunity to compare staff communication in two different workstation designs. Observations and questionnaires compared nurse and PCT communication in the two-unit designs. Descriptive statistics were used to analyze the differences. The hybrid decentralized unit had increased use of hands-free communication technology and hallway communication by nurses and PCTs, and increased patient room communication by nurses. Perceptions of communication between nurses and PCTs and congruency of priorities for care were similar for both units. The locator badge technology had limited adoption. Replacement of nurse workstations with new construction or remodeling impact staff communication patterns, necessitating that nurse leaders understand the impact of design and technology on communication.

    Practice-based learning is important in clinical teaching of nursing and midwifery as students develop the necessary competencies and confidence aligned by the outcomes of their learning programs. However, in Malawi, research shows that clinical teaching in neonatal nursing has not been given adequate consideration. This article reports on challenges faced by educators and students in clinical teaching and learning in neonatal nursing for nurse-midwife technicians. An explorative qualitative study was conducted. Data were collected through 23 focus group discussions with 140 students and 31 clinical teachers from eight nursing colleges. Audiorecorded data were transcribed verbatim and analyzed using Hennink's content analysis stages. Challenges faced by clinical teachers and students were short duration and variation in clinical placements, lack of emphasis in clinical teaching, and lack of skills among clinical staff. Nursing training institutions should maximize student learning opportunities in neonatal nursing practice by creating more practice-based learning opportunities that meet the students' needs.

    Full Text Available In recent years European Commission has developed a set of documents for Members States tracing, directly or indirectly, recommendations for the transformation of the European city. The paper wants to outline which future EU draws for the city, through an integrated and contextual reading of addresses and strategies contained in the last documents, a future often suggested as Smart City. Although the three main documents (Cohesion Policy 2014-2020 of European Community, Digital Agenda for Europe and European Urban Agenda face the issue of the future development of European cities from different points of view, which are respectively cohesion social, ICT and urban dimension, each of them pays particular attention to urban and territorial dimension, identified by the name of Smart City. In other words, the paper aims at drawing the scenario of evolution of Smart Cities that can be delineated through the contextual reading of the three documents. To this end, the paper is divided into three parts: the first part briefly describes the general contents of the three European economic plan tools; the second part illustrates the scenarios for the future of the European city contained in each document; the third part seeks to trace the evolution of the Smart Cities issue developed by the set of the three instruments, in order to provide the framework of European Community for the near future of our cities

    2013-11-01

    I define big data with respect to its size but pay particular attention to the fact that the data I am referring to is urban data, that is, data for cities that are invariably tagged to space and time. I argue that this sort of data are largely being streamed from sensors, and this represents a sea change in the kinds of data that we have about what happens where and when in cities. I describe how the growth of big data is shifting the emphasis from longer term strategic planning to short-term thinking about how cities function and can be managed, although with the possibility that over much longer periods of time, this kind of big data will become a source for information about every time horizon. By way of conclusion, I illustrate the need for new theory and analysis with respect to 6 months of smart travel card data of individual trips on Greater London's public transport systems.

    Community colleges have the ability to play a vital role in the environmental remediation training process for DOE hazardous waste sites. Columbia Basin College in Pasco, Washington is presently involved in such training through numerous workshops offered primarily for employees at the Hanford DOE site, and a two-year associate of applied science degree in Hazardous Materials Management Technology. The workshops are oriented towards specific applied technical training (40 Hour OSHA/80 Hour WISHA, Hazardous/Radioactive Waste Video conference, and others) whereas the degree program provides a broad background in the skills needed for environmental technicians (16 hazmat courses plus support sciences and humanities). The degree program, combined with hazmat work experience, should provide the necessary background for project supervision as well as for skilled field technicians

  5. The City at Stake:

    Directory of Open Access Journals (Sweden)

    Sophie Esmann Andersen

    2009-12-01

    Full Text Available Studies of the city have been addressed from many different approaches such as law, political science, art history and public administration, in which the eco-nomic, political and legal status of the city have played a major role. However, a new agenda for conceptualizing the city has emerged, in which the city assumes new roles. By using stakeholder theory as a framework for conceptualizing the city, we argue that the city assumes a political-economic agenda-setting role as well as providing a stage for identity constructions and relational performances for consumers, organizations, the media, politicians and other stakeholders. Stakeholder theory allows us to conceptualize the city as being constituted by stakes and relationships between stakeholders which are approached from three analytical positions (modern, postmodern and hypermodern, respectively, thereby allowing us to grasp different stakes and types of relationships, ranging from functional and contractual relationships to individualized and emotionally driven or more non-committal and fluid forms of relationships. In order to support and illustrate the analytical potentials of our framework for conceptualizing urban living, we introduce a project which aims to turn the city of Aarhus into a CO2-neutral city by the year 2030, entitled Aarhus CO2030. We conclude that applying stakeholder theory to a hyper-complex organization such as a city opens up for a reconceptualization of the city as a web of stakes and stakeholder relations. Stakeholder theory contributes to a nuanced and elaborate understanding of the urban complexity and web of both enforced and voluntary relationships as well as the different types of relationships that characterize urban life.

    Malaria is still one of the most important public health problems worldwide. The diagnosis of this disease is still mainly based on thick blood films.  To evaluate the knowledge about malaria diagnosis of the technicians of the public health network in Luanda, Angola, by means of a survey.  This survey was carried out in three phases. In the first one, open interviews were done to technicians related with the different procedures for malaria diagnosis. In the second one, a preliminary questionnaire was prepared and evaluated. In the third phase, a definitive questionnaire was applied to 120 technicians from Luanda between April and July, 2013. The proportions of correct and incorrect answers were compared for every question of the survey.  Significantly higher proportions of incorrect answers (p<0.05) were found in the questions related to clinical manifestations, 68/52 (p<0.05), species of Plasmodium according to geographical areas, 76/44 (p<0.05), the type of granulations according to species, 96/24 (p<0.01), the class of microscope magnifying glasses used to observe the thick smear, 105/15 (p<0.01), the thick smear report, 76/44 (p<0.01), the time and preparation of different stain solutions, 81/39 (p<0.01), and the number of parasites counted per 200 leukocytes, 96/24 (p<0.01).  Various failures for the microscopic diagnosis of malaria were observed amongst the evaluated technicians. These results will be useful as a baseline study before applying an educational intervention aimed to improve the quality of malaria diagnosis in Luanda's laboratory network.

    Full Text Available Objectives: To evaluate the impact of a pharmacy-technician centered medication reconciliation (PTMR program by identifying and quantifying medication discrepancies and outcomes of pharmacist medication reconciliation recommendations. Methods: A retrospective chart review was performed on two-hundred patients admitted to the internal medicine teaching services at Cooper University Hospital in Camden, NJ. Patients were selected using a stratified systematic sample approach and were included if they received a pharmacy technician medication history and a pharmacist medication reconciliation at any point during their hospital admission. Pharmacist identified medication discrepancies were analyzed using descriptive statistics, bivariate analyses. Potential risk factors were identified using multivariate analyses, such as logistic regression and CART. The priority level of significance was set at 0.05. Results: Three-hundred and sixty-five medication discrepancies were identified out of the 200 included patients. The four most common discrepancies were omission (64.7%, non-formulary omission (16.2%, dose discrepancy (10.1%, and frequency discrepancy (4.1%. Twenty-two percent of pharmacist recommendations were implemented by the prescriber within 72 hours. Conclusion: A PTMR program with dedicated pharmacy technicians and pharmacists identifies many medication discrepancies at admission and provides opportunities for pharmacist reconciliation recommendations.

    Considering the education required for the next generation of clinical laboratory technicians in terms of elements necessary for the technicians, it is generally important for them to be "needed in the medical field", and the three-year educational institutions for training them are expected to nurture technicians who can work with "skills of immediate use." Herein, the phrase "skills of immediate use" does not simply signify knowledge and techniques, but signifies skills including behavior as medical staff. In addition, "growth potential" permitting continuous growth with self-education and aspiration for improvement after gaining employment is of significance. We refer to the "skills of immediate use" and the "growth potential" integrally as "Genba-ryoku(on-site capabilities)", and have striven for improvement in those capabilities as a basic educational policy of our school. In any period, the medical field needs medical staff who can perform greetings, cleaning, etc., as sound practices and who are well-mannered. It is my belief that educational institutions have to fulfill their mission by nurturing medical staff who possess "toughness to work unaided" as well as a "gentle mind."

    Occupational exposure to lead is common among automobile technicians and constitutes 0.9% of total global health burden with a majority of cases in developing countries. The aim of this study was to determine and compare the blood lead levels of automobile technicians in roadside and organised garages in Lagos State, Nigeria. This was a comparative cross-sectional study. Data were collected using interviewer-administered questionnaires. Physical examinations were conducted and blood was analysed for lead using atomic spectrophotometery. Statistical analyses were performed to compare the median blood lead levels of each group using the independent sample (Mann-Whitney U) test. Seventy-three (40.3%) of the organised compared to 59 (34.3%) of the roadside groups had high blood lead levels. The organised group had statistically significant higher median blood lead levels of, 66.0 µg/dL than the roadside 43.5 µg/dL (P Automobile technicians in organised garages in Lagos have higher prevalence of elevated blood lead levels and higher median levels than the roadside group. Preventive strategies against lead exposures should be instituted by the employers and further actions should be taken to minimize exposures, improve work practices, implement engineering controls (e.g., proper ventilation), and ensure the use of personal protective equipment.

    Occupational exposure to petroleum products is known to be associated with a number of health risks as well as adverse effects on haematological indices. To evaluate the effect of exposure to petroleum products on haematological parameters in automobile mechanics in Nnewi, south-east Nigeria. Fifty (50) automobile technicians and 50 healthy controls participated in the study. Full blood count was performed for each participant using the automated Sysmex haemocytometer (Model PCE 210) while data analysis was done using the SPSS (statistical package for social sciences) version 16 computer soft ware (Chicago, IL, Inc.). Results were expressed as frequencies, means and standard deviations; comparison of haematological parameters was made between subjects and controls and at different durations of exposure using the students' t-test and analysis of variance (ANOVA), respectively. The level of statistical significance was p < 0.05 (at 95% CI). Ethical approval was obtained from the Institutional review board and all participants gave informed consent. There red blood cell count (RBC) and haematocrit were significantly lower while the platelet count was significantly higher in test subjects compared with controls (p values; 0.04, 0.03 and 0.01, respectively). Correspondingly, the mean cell volume (MCV) and mean cell haemoglobin (MCH) were significantly lower in test subjects compared with controls (p = 0.62 and 0.03, respectively). The red cell count, MCV and platelet count significantly decreased with increasing duration of work exposure (p = 0.001, respectively). Occupational exposure to petroleum products adversely affects blood counts, with a significant decrease in RBC, MCV and platelet count as duration of exposure increases.

    Emergency medical technicians (EMTs) in Iran experience concerning levels of workplace violence, although until now there has been no investigation of this phenomenon. The objectives of the present study were to describe the exposure of Iranian EMTs to workplace violence and to identify the importance of related factors from their viewpoint. In this descriptive, exploratory study, 160 EMTs agreed to participate in a survey that collected data regarding their exposure to the following forms of workplace violence: verbal abuse, physical assault, cultural harassment, sexual harassment and sexual assault. A total of 138 questionnaires were returned, representing a response rate of 86%. The majority of participants 75% (n = 103) experienced at least one form of workplace violence in the 12 months before completing the questionnaire. The most frequently reported form of workplace violence was verbal abuse (71%), followed by physical assault (38%) and cultural harassment (9%). Violence resulting in serious injuries was reported by only 4% of participants, with no more than 8% of participants experiencing workplace violence that included the use of weapons. The most reported response to workplace violence was to 'invite the offender to calm down'. Participants took this approach because they believed that 'follow up of workplace violence is ineffectual' (34%), considered the workplace violence as a common in their job (30%), and did not know whom to report workplace violence to (13%). Iranian EMTs experience a considerable amount of workplace violence. The present study highlights the recommendation for formal training programmes and clearer protocols about how to manage workplace violence, especially verbal abuse in the Iranian prehospital setting. © 2011 The Authors.

    Russ-Sellers, Rebecca; Blackwell, Thomas H

    2017-07-01

    Medical schools are encouraged to introduce students to clinical experiences early, to integrate biomedical and clinical sciences, and to expose students to interprofessional health providers and teams. One important goal is for students to gain a better understanding of the patients they will care for in the future and how their social and behavioral characteristics may affect care delivery. To promote early clinical exposure and biomedical integration, in 2012 the University of South Carolina School of Medicine Greenville incorporated emergency medical technician (EMT) training into the curriculum. This report describes the program; outlines changes (made after year 1) to improve biomedical integration; and provides a brief analysis and categorization of comments from student reflections to determine whether particular themes, especially related to the hidden curriculum, appeared. Medical students wrote frequently about EMT-related experiences: 29% of reflections in the charter year (1.2 per student) and 38% of reflections in the second year (1.5 per student) focused on EMT-related experiences. Reflections related to patient care, professionalism, systems-based practice, and communication/interpersonal skills. The frequency of themes in student reflections may provide insight into a medical program's hidden curriculum. This information may serve to inform curricula that focus on biosocial elements such as professionalism and communication with the goal of enhancing future physicians' tolerance, empathy, and patient-centeredness. The authors plan to conduct further qualitative analysis of student reflections to iteratively revise curricula to address gaps both in learning and in the differences between the explicit curriculum and actual experiences.

    Directory of Open Access Journals (Sweden)

    Eric Slater

    2015-08-01

    Full Text Available This article explores new dimensions of the global city in light of the correlation between hegemonic transition and the prominence of financial centers. It counterposes Braudel’s historical sequence of dominant cities to extant approaches in the literature, shifting the emphasis from a convergence of form and function to variations in history and structure. The marked increase of finance in the composition of London, New York and Tokyo has paralleled each city’s occupation of a distinct niche in world financial markets: London is the principal center of currency exchange, New York is the primary equities market, and Tokyo is the leader in international banking. This division expresses the progression of world-economies since the nineteenth century and unfolds in the context of the present hegemonic transition. By combining world-historical and city-centered approaches, the article seeks to reframe the global city and overcome the limits inherent in the paradigm of globalization.

    This article reflects on the challenges for urban planning posed by the emergence of smart cities in network societies. In particular, it reflects on reductionist tendencies in existing smart city planning. Here the concern is with the implications of prior reductions of complexity which have been...... undertaken by placing primacy in planning on information technology, economical profit, and top-down political government. Rather than pointing urban planning towards a different ordering of these reductions, this article argues in favor of approaches to smart city planning via complexity theory....... Specifically, this article argues in favor of approaching smart city plans holistically as topologies of organized complexity. Here, smart city planning is seen as a theory and practice engaging with a complex adaptive urban system which continuously operates on its potential. The actualizations in the face...

    2014-01-01

    It is difficult to acquire a chest X-ray of a crying infant at maximum inspiration. A computer program was developed for technician training. Method. Video clips of 3 babies were used and the moment of deepest inspiration was determined in the single-frame view. 12 technicians simulated chest radiographs at normal video speed by pushing a button. The computer program stopped the video and calculated the period of time to the optimal instant for a chest X-ray. Demonstration software can be tested at website online. Every technician simulated 10 chest X-rays for each of the 3 video clips. The technicians then spent 40 minutes practicing performing chest X-rays at optimal inspiration. The test was repeated after 5, 20, and 40 minutes of practice. Results. 6 participants showed a significant improvement after exercises (collective 1). Deviation from the optimal instant for taking an X-ray at inspiration decreased from 0.39 to 0.22 s after 40 min of practice. 6 technicians showed no significant improvement (collective 2). Deviation decreased from a low starting value of 0.25 s to 0.21 s. Conclusion. The tested computer program improves the ability of radiology technicians to take a chest X-ray at optimal inspiration in a crying child

    The concept of a livable smart city presented in this book highlights the relevance of the functionality and integrated resilience of viable cities of the future. It critically examines the progressive digitalization that is taking place and identifies the revolutionized energy sector as the basis of urban life. The concept is based on people and their natural environment, resulting in a broader definition of sustainability and an expanded product theory. Smart City 2.0 offers its residents many opportunities and is an attractive future market for innovative products and services. However, it presents numerous challenges for stakeholders and product developers.

    2013-04-01

    Full Text Available In the quest for achieving sustainable cities, Intelligent and Knowledge City Programmes (ICPs and KCPs represent cost-efficient strategies for improving the overall performance of urban systems. However, even though nobody argues on the desirability of making cities “smarter”, the fundamental questions of how and to what extent can ICPs and KCPs contribute to the achievement of urban sustainability lack a precise answer. In the attempt of providing a structured answer to these interrogatives, this paper presents a methodology developed for investigating the modalities through which ICPs and KCPs contribute to the achievement or urban sustainability. Results suggest that ICPs and KCPs efficacy lies in supporting cities achieve a sustainable urban metabolism through optimization, innovation and behavior changes.

    2013-07-01

    Full Text Available A territory, a city, a neighbourhood are all ecosystems; a mixture of chemico-physical and organic elements related to each other. That which defines an ecological system is the set of rules and characteristics which condition its relationships, and its duration in time is guaranteed by its efficiency and internal organization which applied to the city is translated in the reduction of the use of natural resources and in the increase of social organization. To increase the efficiency of the urban systems is the necessary condition for the formulation of ecological city planning favouring the maximum liveability of sites. Liveability is directly correlated to the optimization of numerous elements (public space, equipment, services, building techniques, innovative technology, social cohesion, biodiversity. To carry out such objectives, ecological city planning proposes a new model of town planning on three levels (subsoil, ground level, and upper level.

These views are expressed in their reflections and photos. Against common beliefs about modern youth, these young people are not obsessed with their gadgets. They use them quite well to take a fresh look at the environment. It should be noted that the project has attracted, among others, starting architects, especially those who have experience in participatory design. It is an interesting attempt to get in tune with the pulse of the city, with the common rhythm of images, which makes the city and its inhabitants a single whole.

    Lewis, G; David, A; Andréasson, S; Allebeck, P

    1992-07-18

    Prevalence of schizophrenia and rates of first admission to hospital for this disorder are higher in most modern industrialised cities, and in urban compared with rural areas. The "geographical drift" hypothesis (ie, most schizophrenics tend to drift into city areas because of their illness or its prodrome) has remained largely unchallenged. We have investigated the association between place of upbringing and the incidence of schizophrenia with data from a cohort of 49,191 male Swedish conscripts linked to the Swedish National Register of Psychiatric Care. The incidence of schizophrenia was 1.65 times higher (95% confidence interval 1.19-2.28) among men brought up in cities than in those who had had a rural upbringing. The association persisted despite adjustment for other factors associated with city life such as cannabis use, parental divorce, and family history of psychiatric disorder. This finding cannot be explained by the widely held notion that people with schizophrenia drift into cities at the beginning of their illness. We conclude that undetermined environmental factors found in cities increase the risk of schizophrenia.

  17. The Joint Cities

    Directory of Open Access Journals (Sweden)

    Romano Fistola

    2010-04-01

    Full Text Available The new connections, which high speed train allows to activate among the metropolitan systems, seem to be able to give life to new urban macro-structures for which the transfer time, among the main poles of the railway segment, becomes comparable to an inside moving into the city and therefore considered as an inter-functional mobility. The tunnel effect generated by the high speed connection seems to be able to allow a new temporal and functional joint among the metropolitan systems consequently supporting the possibility, for the users, to move themselves among the different urban functions belonging to the different cities. The birth of these urban aggregations seems to drive towards new megalopolis, which we can define for the first time with the term: joint-city. For this new metropolitan settlement it seems to be very interesting to investigate the constitutive peculiarities, the systemic articulation, its relational structures, the evolutionary scenarios, and so on. The urban functions (activities can be considered as structures of relationships between people that allows to define "organizational links" inside the community; the urban functions are located in specific places inside urban container or in open spaces. The urban functions represent the urban engines and the functional system can be thought as the “soul of the city", abstract but essential to its survival. In the definition set out here the analysis is carried out for many interconnected urban functional system points (specifically those in Rome and Naples. The new high speed railway has to be considered not only as a new channel of mobility between cities, but as a real possibility of joint between the functional systems of the two centres. A final consideration can be carried out in relation to the possibility of implementing new measures of governance of urban transformations considering the new macro-city: the "Joint City".

  18. Earth's City Lights

    Science.gov (United States)

    2002-01-01

    This image of Earth's city lights was created with data from the Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS). Originally designed to view clouds by moonlight, the OLS is also used to map the locations of permanent lights on the Earth's surface. The brightest areas of the Earth are the most urbanized, but not necessarily the most populated. (Compare western Europe with China and India.) Cities tend to grow along coastlines and transportation networks. Even without the underlying map, the outlines of many continents would still be visible. The United States interstate highway system appears as a lattice connecting the brighter dots of city centers. In Russia, the Trans-Siberian railroad is a thin line stretching from Moscow through the center of Asia to Vladivostok. The Nile River, from the Aswan Dam to the Mediterranean Sea, is another bright thread through an otherwise dark region. Even more than 100 years after the invention of the electric light, some regions remain thinly populated and unlit. Antarctica is entirely dark. The interior jungles of Africa and South America are mostly dark, but lights are beginning to appear there. Deserts in Africa, Arabia, Australia, Mongolia, and the United States are poorly lit as well (except along the coast), along with the boreal forests of Canada and Russia, and the great mountains of the Himalaya. The Earth Observatory article Bright Lights, Big City describes how NASA scientists use city light data to map urbanization. Image by Craig Mayhew and Robert Simmon, NASA GSFC, based on DMSP data

  19. Universities scale like cities.

    van Raan, Anthony F J

    2013-01-01

    Recent studies of urban scaling show that important socioeconomic city characteristics such as wealth and innovation capacity exhibit a nonlinear, particularly a power law scaling with population size. These nonlinear effects are common to all cities, with similar power law exponents. These findings mean that the larger the city, the more disproportionally they are places of wealth and innovation. Local properties of cities cause a deviation from the expected behavior as predicted by the power law scaling. In this paper we demonstrate that universities show a similar behavior as cities in the distribution of the 'gross university income' in terms of total number of citations over 'size' in terms of total number of publications. Moreover, the power law exponents for university scaling are comparable to those for urban scaling. We find that deviations from the expected behavior can indeed be explained by specific local properties of universities, particularly the field-specific composition of a university, and its quality in terms of field-normalized citation impact. By studying both the set of the 500 largest universities worldwide and a specific subset of these 500 universities--the top-100 European universities--we are also able to distinguish between properties of universities with as well as without selection of one specific local property, the quality of a university in terms of its average field-normalized citation impact. It also reveals an interesting observation concerning the working of a crucial property in networked systems, preferential attachment.

  20. Network cities and externalities

    Rafael Boix Domènech

    2004-01-01

    Full Text Available The concept of «agglomeration economies» explains the existence of advantages derived from the concentration of population and activity. However, it does not explain the existence of spatially dynamic external economies. Network economies generated in networks of cities correspond to this last type, since they are generated from the interaction between urban units, linked by a network relationship. The objective of this research is to advance in the study of the relationship between the networks of cities and the generation of external economies. The research is divided in four parts: first we expose the link between networks of cities and external economies. The second part outlines a model for the combined measuring of the concentration and network economies. The third part explains the results of applying the model to a case of study: the network of cities of Catalonia. The results suggest that there is a causal relationship between the organization of the urban units forming networks of cities and the generation of external economies that affect growth and economic development. Finally, conclusions and policy implications are drawn up.

It also reveals an interesting observation concerning the working of a crucial property in networked systems, preferential attachment.

    The City of Hamilton has launched an extensive energy planning exercise that examines the possibility of steep increases in oil and natural gas prices. This report examined and illustrated the issue of oil and gas price points. The report also examined and presented the city's role in an era of energy constraints, focusing on the city's transit system and its vehicle fleet. In addition, in response to City Council's direction, the report presented the aerotropolis proposal and discussed freight transport issues. Specific topics of discussion included oil and natural gas prospects; prospects for high oil and natural gas prices; impacts of fuel price increases; strategic planning objectives for energy constraints; reducing energy use by Hamilton's transport and in buildings; and land-use planning for energy constraints. Energy production opportunities involve the use of solar energy; wind energy; deep lake water cooling (DLWC); hydro-electric power; energy from waste; biogas production; district energy; and local food production. Economic and social development through preparing for energy constraints and matters raised by city council were also presented. The report also demonstrated how an energy-based strategy could be paid for and its components approved. The next steps for Hamilton were also identified. refs., tabs., figs

    Full Text Available Objectives: This work is based on the perception of technicians and nursing assistants, in relation to the supervision of nurses examining what type of monitoring that are submitted, if it is in the form of leadership or managerial where we will work the negative points on supervision, evidenced by technical and nursing assistants, in an Intensive Care Unit (ICU. Method: This is a search with the qualitative methodology, which will be developed in the ICU of a public medical institution in Volta Redonda, where the instrument is to search through a questionnaire that will apply to technicians and nursing assistants, the ICU, in the period from July to August 2008. Conclusion: During this study realized that the quality of nursing care, the interaction of the nursing team and communication, can actually be modified with the leadership of the nurse. The need is urgent for change, the nurse not only becomes unsafe for dealing with this team, and makes it whole team is without prejudice, motivated, with that you get a poor service.

    Full text: As a result of an aging workforce at US federal agencies and federal contractors’ workforce, it is projected that over 20% of the current workforce will be retiring over the next decade. Typically, the institutional knowledge and technical expertise is possessed by senior staff members approaching retirement. In many instances, this knowledge is lost once the employee retires; therefore, creating a huge gap in knowledge and knowledge transfer to new employees joining the workforce. Companies and federal agencies should develop methods to not only maintain the corporate knowledge and technical expertise, but also a transfer this valuable knowledge to the next generation of scientist, engineer and technicians entering the workforce. For example, Florida International University supports DOE-EM’s knowledge transfer through the DOE Fellows STEM programme and the development of international technology platform such as the Knowledge Management Information Tool for nuclear decommissioning (KM-IT). This paper will discuss the knowledge transfer issues faced by federal agencies and federal contractors and innovative tools to capture, store, maintain, and transfer the knowledge to the new generation of scientists, engineers and technicians entering the workplace.

    Full Text Available The competition of maintenance services in the offshore wind industry is continually increasing. The quality of the services acts as the distinguishing feature in the industry. Furthermore, there are public standards, which lead to the permanent necessity to offer further education and training programs for employees. To meet the requirements for further training in the specific field of application within the offshore wind industry, a gamified e-learning application has been developed and is introduced in this paper. It consists of a complete solution, which contains the automated analysis of service protocols to identify qualification needs, the involvement of service technicians in the generation of learning materials, the preparation, transmission as well as the further development of those materials in accordance with the principles of e-learning. Finally, the solution contains a gamified mobile application for qualification, which is designed to meet the individual learning needs of the service technicians. This concept paper follows a problem-centred approach. Based on the current state of technology and research, the problem and motivation are identified and the urgency is verified. Furthermore, a detailed specification of the solution and a first implementation approach is presented.

    Walking is a mode of perceiving the city which also contributes to health and social benefits. This paper studies the influence of the socio-cultural aspects on the practice of walking and the meaning of walkscapes in Riyadh, one of the most auto-dependent and gender-segregated cities on the Arab....... The results of mapping where the respondents walk show a city consisting of gender-specific walkscapes. Indoor environments, such as shopping malls, function as ‘urban shelters’ for women, so they use such spaces for walking. On the other hand, young men mainly walk in urban streets, which provide greater...... opportunities for gender interaction. However, streets are socially conceived as men’s walkscapes, which limits women’s presence, especially at certain times of the day. This paper reveals how walking experience, tempo-rhythm, sense of place and range of walkscapes are not only determined by ‘universal’ spatial...

    Ultrafine particles (UFPs; diameter less than 100 nm) are ubiquitous in urban air, and an acknowledged risk to human health. Globally, the major source for urban outdoor UFP concentrations is motor traffic. Ongoing trends towards urbanisation and expansion of road traffic are anticipated to further increase population exposure to UFPs. Numerous experimental studies have characterised UFPs in individual cities, but an integrated evaluation of emissions and population exposure is still lacking. Our analysis suggests that the average exposure to outdoor UFPs in Asian cities is about four-times larger than that in European cities but impacts on human health are largely unknown. This article reviews some fundamental drivers of UFP emissions and dispersion, and highlights unresolved challenges, as well as recommendations to ensure sustainable urban development whilst minimising any possible adverse health impacts.

    More than half of the global population currently lives in cities, with an increasing trend for further urbanization. Living in cities is associated with increased population density, traffic noise and pollution, but also with better access to health care and other commodities. This review is based on a selective literature search, providing an overview of the risk factors for mental illness in urban centers. Studies have shown that the risk for serious mental illness is generally higher in cities compared to rural areas. Epidemiological studies have associated growing up and living in cities with a considerably higher risk for schizophrenia. However, correlation is not causation and living in poverty can both contribute to and result from impairments associated with poor mental health. Social isolation and discrimination as well as poverty in the neighborhood contribute to the mental health burden while little is known about specific interactions between such factors and the built environment. Further insights on the interaction between spatial heterogeneity of neighborhood resources and socio-ecological factors is warranted and requires interdisciplinary research.

  16. WHO Healthy Cities Programme.

    1996-03-01

    This article identifies some urban health challenges and discusses World Health Organization (WHO) concepts of public health, a Municipal Health Plan, and the WHO Healthy Cities Program (HCP). A healthy city is defined as one that continually creates and improves the physical and social environment and expands community resources for enabling the mutual support among population groups for living. Urbanization is advancing rapidly, but government resources are not keeping pace with people's needs. By 1990, at least 600 million urban people in developing countries faced life and health threats. There is poverty, inadequate food and shelter, insecure tenure, physical crowding, poor waste disposal, unsafe working conditions, inadequate local government services, overuse of harmful substances, and environmental pollution. Poor people in cities frequently must satisfy all their basic needs in health, welfare, and employment. There is exposure to early sexual activity of adolescents, transient relationships, high levels of prostitution, and limited birth control. Unsustainable use of natural resources and environmental destruction pose threats to urban productivity and restrict future development options. The WHO launched a "Health for All" campaign in 1978, based on 4 basic principles. The HCP, which is based on these principles, has expanded to many cities. It measures the health burden and makes health issues relevant and understandable to local agencies through analysis and policy advocacy. The Municipal Health Plan facilitates awareness of environmental and health problems in schools, work and marketplaces, health services, and among other organizations.
