  10. Progress report, Biology and Health Physics Division, January 1 to March 31, 1978

    International Nuclear Information System (INIS)

    Progress of work in Biology and Health Physics Division is reported for first quarter 1978. Measurements of liquid and plastic scintillator responses over a wide range of gamma-ray energies and calculations of the shape of the Compton electron distribution have been made for different scintillator sizes. Other work performed in health physics included determination of errors involved in accurate determination of dose-equivalents resulting from tritium ingestion, and development of radiation monitors and techniques for using them to best advantage. A wide range of environmental studies were underway during the quarter, notably 14C/12C ratio measurement using an accelerator-spectrometer and contiuing studies of the beneficial uses of thermal effluents. Development of computer linkage techniques for medical records continued. Practical applications of the approach include linkage of personal exposure histories with death records pertaining to the exposed individuals. Work in the Biology Branch has continued to focus upon the effects of radiation on a variety of living organisms, ranging from bacterial viruses to humans. The principal sensitive target for long-term biological effects of radiation on all living organisms is DNA. The chemical nature of the damage caused in DNA by radiation and the response of cells to this damage is being studied by a variety of biochemical and genetic techniques. A review of literature on the causes of cancer in humans has continued. If effects are linearly related to total dose, as is normally assumed for purposes of radiation protection, then the total number of fatal cancers predicted to arise from the use of nuclear power in the future should be about 100 times less than the number induced by urban air pollution resulting from the combustion of coal and oil to produce the same amount of electricity. (OST)

  11. Progress report, Biology and Health Physics Division, April 1 to June 30, 1977

    International Nuclear Information System (INIS)

  12. Progress report, Biology and Health Physics Division, April 1 to June 30, 1978

    International Nuclear Information System (INIS)

    The effects of neutrons reflected by the body of a wearer of a neutron threshold activation detector have been determined experimentally. Agreement with the previously calculated effect was good. Calculations and experiments are in progress on the response of organic scintillators to fast neutron and gamma radiation. Other work in health physics included examination of the feasibility of using water-permeable membranes to separate HTO from HT and design of instrumentation for measuring discharge of radio-xenons from a Mo-99 production plant. A variety of environmental research programs included studies dealing with the effects of thermal stress on food-chain organisms in fresh water and mobility of arsenic in sand columns. Computer studies on linked health records will be phased out at Chalk River Nuclear Laboratories. Similar work will be performed at Statistics Canada, the University of British Columbia, and in Hawaii under its cancer register. Work in biology has continued to focus upon the effects of radiation on a variety of organisms, ranging from bacterial viruses to humans. The principal target for long-term biological effects of radiation on all living organisms is DNA. The chemical nature of damage caused in DNA by radiation and the response of cells to this damage is being studied by a variety of biochemical and genetic techniques. Studies on cultured skin cells from various humans have shown interesting characteristics associated with different rare hereditary diseases. It has now been shown that repair-deficient ataxia telangiectasia (AT) cells are surprisingly different from repair-proficient AT cells in their reponse to ultraviolet light at 313 nm. (OST)

  13. Progress report, Biology and Health Physics Division, July 1 to September 30, 1978

    International Nuclear Information System (INIS)

    A simple code for unfolding neutron spectra from scintillation measurements is being investigated. Work is in progress to provide individual calibration factors for the dosimeters used in radiation monitoring badges. Low-level gamma radiation survey meters using digital displays are being tested by users. Tests of a perfluorosulfonic acid polymer, in the form of thin-walled tubing, have shown that it can adequately separate water vapour from hydrogen in an air sample stream. A nepheline-syenite glass block containing moderate levels of fission product radionuclides was successfully recovered from the test area and shipped to Whiteshell Nuclear Research Establishment for examination and analysis. This block was one of twenty-five blocks placed in the ground twenty years ago in the first test disposal of waste fission products incorporated into a glass matrix. Cores of sandy aquifer material, contaminated by the 1954 and 1955 experimental liquid radioactive waste disposals, were dewatered. The pore waters and soils were analyzed to determine field distribution coefficients for 90Sr and 137Cs. These are useful data for pathways analysis modelling of radionuclide migration from the proposed Canadian fuel wastes geological repository. Field studies are underway to assess the effects of low-grade heat on rooted aquatic plants. Work in biology has continued to focus upon the effects of radiation on the DNA of a variety of living organisms, ranging fro bacterial viruses to humans. Cells from patients suffering from ataxia telangiectasia (AT) are at least 2.8 times more sensitive to acute γ-radiation than are comparable cells from normal persons; however, the ratio of sensitivites is about 1.8 times for neutron irradiation. It is possible, therefore, that neutrons might be advantageous for clinical therapy of cancer in AT patients. (OST)

  2. An electrostatic model for biological cell division

    CERN Document Server

    Faraggi, Eshel

    2010-01-01

    Probably the most fundamental processes for biological systems is their ability to create themselves through the use of cell division and cell differentiation. In this work a simple physical model is proposed for biological cell division. The model consists of a positive ionic gradient across the cell membrane, and concentration of charge at the nodes of the spindle and on the chromosomes. A simple calculation, based on Coulomb's Law, shows that under such circumstances a chromosome will tend to break up to its constituent chromatids and that the chromatids will be separated by a distance that is an order of thirty percent of the distance between the spindle nodes. Further repulsion between the nodes will tend to stretch the cell and eventually break the cell membrane between the separated chromatids, leading to cell division.

    International Nuclear Information System (INIS)

    Research and Development (R and D) activities of the Radiochemistry Division of Bhabha Atomic Research Centre, Bombay during 1986 are reported. Some of the highlights of these activities are solvent extraction studies on U(VI) and trivalent Am, Cm and Cf, low energy and medium energy fission of actinides, nuclear reactions on 197Au, perturbed angular correlation studies on polymerisation of Hf(IV) and EPR studies on Am doped BaCO3, SrSO4 and LiKSO4. Investigations on the complexation, hydrolysis and speciation of Am(III) in phosphate and carbonate media have been carried out with a view to understanding the behaviour of Am ions in natural and waste water systems. The angular momentum studies have shown that fission fragment angular momentum increases with increasing excitation energy and angular momentum of the fissioning due to coupling of various collective rotational degrees of freedom. Angular distribution studies have shown that asymmetric mode fragments have higher anisotropy compared to the symmetric mode fragments due to extended saddle point shape and hence larger effective moment of inertia. Studies on alpha induced nuclear reaction on 197Au have provided evidence for non-equilibrium particle emission process as against the expected compound nucleus mechanism. EPR and TSL studies on actinide doped solids have shown stabilisation of radicals produced on irradiations as well as provided evidence for chemically induced dynamic nuclear polarization. At the end of the report, a list of publications of the staff members of the Division during the report is given. These publications include journal articles, conference paper and technical reports.

  3. Progress report 1979 July 01 to September 30, Health Sciences Division

    International Nuclear Information System (INIS)

    In September 1979, the Biology and Health Physics Division and the Medical Division were amalgamated to form the Health Sciences Division. This is the first progress report of the new division. A new TLD reader for semi-automatic handling of individual TLD chips has been commissioned. As high range radiation detectors for spent fuel monitoring, optical photo-diodes show performance similar to that of silicon rectifiers. Studies continue on the use of water-permeable plastic membranes in tritium monitoring, particularly where it is important to distinguish between 3H in elemental form and combined as water. The first of a series of radionuclide injection experiments was made in the sand aquifer near Perch Lake. These experiments are to develop methods for studying radionuclide transport in fractured rock. Investigations of soil and groundwater in the vicinity of waste management areas have shown that tritium is the only radionuclide present in significant quantities. Radiation damage to DNA and subsequent repair is being studied by observing both somatic and genetic effcts. Rare hereditary human diseases that present clinical or laboratory features indicative of defects in the DNA repair mechanism are being studied. Work on various metabolic models that describe retention and distribution of radionuclides in humans has continued with emphasis on tritium as HT, carbon as CO2, and compounds of the alkaline earth and actinide elements. Committed effective dose equivalent conversion factors for infants and adults have been calculated for 380 classes of compounds of radionuclide and intake routes, for 65 elements. (OT)

  7. Discovering biological progression underlying microarray samples.

    Directory of Open Access Journals (Sweden)

    Peng Qiu

    2011-04-01

    Full Text Available In biological systems that undergo processes such as differentiation, a clear concept of progression exists. We present a novel computational approach, called Sample Progression Discovery (SPD, to discover patterns of biological progression underlying microarray gene expression data. SPD assumes that individual samples of a microarray dataset are related by an unknown biological process (i.e., differentiation, development, cell cycle, disease progression, and that each sample represents one unknown point along the progression of that process. SPD aims to organize the samples in a manner that reveals the underlying progression and to simultaneously identify subsets of genes that are responsible for that progression. We demonstrate the performance of SPD on a variety of microarray datasets that were generated by sampling a biological process at different points along its progression, without providing SPD any information of the underlying process. When applied to a cell cycle time series microarray dataset, SPD was not provided any prior knowledge of samples' time order or of which genes are cell-cycle regulated, yet SPD recovered the correct time order and identified many genes that have been associated with the cell cycle. When applied to B-cell differentiation data, SPD recovered the correct order of stages of normal B-cell differentiation and the linkage between preB-ALL tumor cells with their cell origin preB. When applied to mouse embryonic stem cell differentiation data, SPD uncovered a landscape of ESC differentiation into various lineages and genes that represent both generic and lineage specific processes. When applied to a prostate cancer microarray dataset, SPD identified gene modules that reflect a progression consistent with disease stages. SPD may be best viewed as a novel tool for synthesizing biological hypotheses because it provides a likely biological progression underlying a microarray dataset and, perhaps more importantly, the

    Calculations of absorbed doses and dose equivalents at various depths in a cylindrical tissue equivalent phantom by monoenergetic neutrons and calculations of quality factors for monoenergetic neutrons in tissue have been extended to neutron energies up to 14.7 MeV. Irradiations of human lymphocytes with low doses of 60Co gamma rays and 14.6 MeV neutrons show a lower initial incidence of DNA strand breaks produced by neutrons than by gamma radiation. Tests are in progress on the relative thermal neutron sensitivities of various commonly used types of TLD phosphor. Studies on soil columns contaminated with radioactive cesium have demonstrated the release of a small portion of the cesium present on the column on filterable particles. Work on the bioavailability of 60Co present in groundwater has indicated that complexed 60Co is less available to plants than added free cobalt. A liquid scintillation method has been successfully used to measure radon-222 in bedrock groundwater. Radiation Biology research activities have been concerned mainly with effects of radiation and tumor promoters on the DNA in blood lymphocytes, a new method of preparing plasmid DNA, relation of oxygen and various free radicals to radiation-induced lethality and genetic changes in yeast, the functions of different DNA repair systems in yeast, induction of DNA damage by ultraviolet light, relationship of radiation sensitivity to hereditary deficiencies in DNA repair systems in cultured human cells, relative biological effectiveness of tritium beta-radiation for induction of breast cancer in rats and the follow-up of past CRNL employees.

    Livingston, A.B. (ed.)

    1989-03-01

    This report covers the research and development activities of the Physics Division for the 1988 fiscal year, beginning October 1, 1987, and ending September 30, 1988. The activities of this Division are concentrated in the areas of experimental nuclear physics, experimental atomic physics, and theoretical nuclear and atomic physics. Operation of the Holifield Heavy Ion Research Facility as a national user facility continues to represent the single largest activity within the Division. This year saw the completion of the acceleration tube upgrade of the 25-MV tandem electrostatic accelerator and the achievement of record terminal potentials, operation for an experiment with 25 million volts on terminal, and successful tests with beam at 25.5 MV. The experimental nuclear physics program continues to be dominated by research utilizing heavy ions. These activities, while continuing to center largely on the Holifield Facility, have seen significant growth in the use of facilities that provide intermediate energies and especially ultrarelativistic beams. The UNISOR program, since its inception, has been intimately associated with the Division and, most particularly, with the Holifield Facility. In addition to the Holifield Facility, the Division operates two smaller facilities, the EN Tandem and the ECR Ion Source Facility, as ''User Resources.'' The efforts in theoretical physics, covering both nuclear and atomic physics, are presented. In addition to research with multicharged heavy ions from the ECR source, the effort on atomic physics in support of the controlled fusion program includes a plasma diagnostics development program. The concentration of this program on optical and laser technology is marked by the change in designation to the Laser and Electro-Optics Lab. A small, continuing effort in elementary particle physics, carried out in collaboration with the University of Tennessee, is reported.

    International Nuclear Information System (INIS)

    The activities of the Division during 1984/85 were again directed towards the general program objectives of the past two years. A shift in emphasis resulted in some organization changes. The increased importance of nuclear safeguards research in the Government's support for the International Atomic Energy Agency program has prompted a re-arrangement of the nuclear physics and science activities. Dr JR. Bird holds the responsibility for the Nuclear Science Section comprising the Nuclear Applications Group, Biomedical and Reactor Applications Group and the Neutron Scattering Group. The newly formed Safeguards and Nuclear Physics Section is headed by Dr J.W. Boldeman and includes the Safeguards Group and Nuclear Physics Group. The organization of the remainder of the Division is unchanged. The work on the electronic properties of hydrogen in silicon has been particularly rewarding and the plasma physics studies received recognition with an IAEA sponsored workshop on Compact Torus Research held in Sydney in March 1985 (author)

  12. Regulation of cell division in higher plants. Progress report

    Energy Technology Data Exchange (ETDEWEB)

    Jacobs, T.W.

    1992-07-01

    Cell division is arguably the most fundamental of all developmental processes. In higher plants, mitotic activity is largely confined to foci of patterned cell divisions called meristems. From these perpetually embryonic tissues arise the plant`s essential organs of light capture, support, protection and reproduction. Once an adequate understanding of plant cell mitotic regulation is attained, unprecedented opportunities will ensue for analyzing and genetically controlling diverse aspects of development, including plant architecture, leaf shape, plant height, and root depth. The mitotic cycle in a variety of model eukaryotic systems in under the control of a regulatory network of striking evolutionary conservation. Homologues of the yeast cdc2 gene, its catalytic product, p34, and the cyclin regulatory subunits of the MPF complex have emerged as ubiquitous mitotic regulators. We have cloned cdc2-like and cyclin genes from pea. As in other eukaryotic model systems, p34 of Pisum sativum is a subunit of a high molecular weight complex which binds the fission yeast p13 protein and displays histone H1 kinase activity in vitro. Our primary objective in this study is to gain baseline information about the regulation of this higher plant cell division control complex in non-dividing, differentiated cells as well as in synchronous and asynchronous mitotic cells. We are investigating cdc2 and cyclin expression at the levels of protein abundance, protein phosphorylation and quaternary associations.

    The research activities of the Division are centered primarily in three areas: experimental nuclear physics, experimental atomic physics, and theoretical nuclear and atomic physics. The largest of these efforts, experimental nuclear physics, is dominated by the heavy ion research program. A major responsibility under this program is the operation of the Holifield Heavy Ion Research Facility as a national user facility. During the period of this report, the facility has begun routine operation for the experimental program. The experimental atomic physics program has two components: the accelerator-based studies of basic collisional phenomena and the studies in support of the controlled fusion program. Also associated with the fusion-related studies are a plasma diagnostics program and the operation of an atomic physics data center. The theoretical physics program, both nuclear and atomic, is covered. This program has benefited this year from the success of the VAX-AP computer system and from the increase in manpower provided by the ORNL/University of Tennessee Distinguished Scientist Program. Smaller programs in applications and high-energy physics are summarized. During the period of this report, we continued to explore possible future extensions of the Holifield Facility. We retain a strong interest in a relativistic heavy-ion collider in the 10 x 10 GeV/nuclear energy range. The ideas for such a facility, described in last year's report, have been modified to utilize the HHIRF 25 MV tandem accelerator as the first stage. Finally, the report concludes with some general information on publications, Division activities, and personnel changes

  7. Concise Review: Asymmetric Cell Divisions in Stem Cell Biology

    Full Text Available Somatic stem cells are rare cells with unique properties residing in many organs and tissues. They are undifferentiated cells responsible for tissue regeneration and homeostasis, and contain both the capacity to self-renew in order to maintain their stem cell potential and to differentiate towards tissue-specific, specialized cells. However, the knowledge about the mechanisms controlling somatic stem cell fate decisions remains sparse. One mechanism which has been described to control daughter cell fates in selected somatic stem cell systems is the process of asymmetric cell division (ACD. ACD is a tightly regulated and evolutionary conserved process allowing a single stem or progenitor cell to produce two differently specified daughter cells. In this concise review, we will summarize and discuss current concepts about the process of ACD as well as different ACD modes. Finally, we will recapitulate the current knowledge and our recent findings about ACD in human hematopoiesis.

    The Health and Safety Research Division (HASRD) of the Oak Ridge National Laboratory (ORNL) continues to maintain an outstanding program of basic and applied research displaying a high level of creativity and achievement as documented by awards, publications, professional service, and successful completion of variety of projects. Our focus is on human health and the scientific basis for measurement and assessment of health-related impacts of energy technologies. It is our custom to publish a division progress report every 18 months that summarizes our programmatic progress and other measures of achievement over the reporting period. Since it is not feasible to summarize in detail all of our work over the period covered by this report (October 1, 1988, to March 30, 1990), we intend this document to point the way to the expensive open literature that documents our findings. During the reporting period the Division continued to maintain strong programs in its traditional areas of R D, but also achieved noteworthy progress in other areas. Much of the Division's work on site characterization, development of new field instruments, compilation of data bases, and methodology development fits into this initiative. Other new work in tunneling microscopy in support of DOE's Human Genome Program and the comprehensive R D work related to surface-enhanced Raman spectroscopy have attained new and exciting results. These examples of our progress and numerous other activities are highlighted in this report.

Since it is not feasible to summarize in detail all of our work over the period covered by this report (October 1, 1988, to March 30, 1990), we intend this document to point the way to the expensive open literature that documents our findings. During the reporting period the Division continued to maintain strong programs in its traditional areas of R ampersand D, but also achieved noteworthy progress in other areas. Much of the Division's work on site characterization, development of new field instruments, compilation of data bases, and methodology development fits into this initiative. Other new work in tunneling microscopy in support of DOE's Human Genome Program and the comprehensive R ampersand D work related to surface-enhanced Raman spectroscopy have attained new and exciting results. These examples of our progress and numerous other activities are highlighted in this report

    Kinemetic shifts have been measured in the β-delayed α-decay of 20Na in order to deduce β-ν angular correlations. Analysis of the data is in progress. In a significant advance in techniques to measure quadrupole moments of isomeric states, the electric field gradient experienced by 147Gd isomers was determined in a target of single-crystal gadolinium using Coulomb excitation. Commissioning of the Alvarez accelerator for the High Current Test Facility continues. The Alvarez tank has been cleaned, reasssembled with some modifications and subjected to initial steps of rf conditioning. A successful test was made of the radiation processing facility. A current of 6 mA was accelerated to 4 MeV and allowed to pass through a 0.75 mm stainless steel window into the fast-flowing cooling water. Conversion measurements were carried out with 19-element thorium and 7- and 37-element uranium targets. Preliminary data for distributions of characteristic radioactive products have been extracted for the 7-element target. Operations of the MP Tandem Accelerator and the main site computing facility are also summarized. (OT)

  3. Environmental and Occupational Safety Division annual progress report for 1984

    International Nuclear Information System (INIS)

    Over 950 radiation workers were monitored at ORNL for both internal and external exposure to ionizing radiation and radioactive materials in 1984, and no employee exceeded 50% of the applicable DOE dose limit. No internal exposure exceeded 10% of the maximum permissible organ burden, as determined by in-vivo gamma spectrometry. Dose readings from 5000 TLDs and 136,000 pocket meters were determined, and more than 5800 calibrations were performed on these devices. Approximately 82,000 radioassays were performed; among these were 1500 urinalyses and 3000 radiochemical analyses. Over 3000 calibrations were performed for approximately 2000 portable and fixed survey instruments. Response teams were identified in support of the Radiological Assistance Program (RAP). Documentation, procedures, and equipment for the RAP vehicle were upgraded. A long-range environmental plan was issued early in the year and again in June 1984 to document the scope and justification for each project. The DEM is developing an environmental information system for managing DOE-ORO and ORNL environmental data. Five hundred eighty-four waste disposal requests containing 5769 items were handled by the Hazardous Materials Control Group during 1984. The Office of Operational Safety made significant progress in the completion of Safety Analysis Reports for existing facilities. The Radiation and Safety Surveys Department is becoming increasingly involved in work resulting in facility improvement, repair, or upgrade as well as decontamination and decommissioning of older facilities

    Study of exotic new isotopes with the on-line isotope separator, ISOL, has begun. Quadrupole moments of isomeric states in lead isotopes have been further investigated. Progress is being made in identifying and overcoming certain insidious background processes in 14C dating with the MP Tandem. The Fast Intense Neutron Source accelerator now operates well at 80% of design current. Development and construction of the Superconducting Cyclotron continues. Operation with larger plasma apertures has given improved beam quality and more beam current than expected from the duoPIGatron ion source. Commissioning of the Alvarez accelerator continues. The practicability of characterizing thick target spallation reactions in terms of ten activities from spallation and fast neutron fission multiplication has been demonstrated. Study of the temperature dependence of the condensate fraction in 4He has been completed. A simple and very successful semiempirical relationship between the reduced superfluid density of liquid 4He and the condensate fraction has been obtained. The source of copper impurities that are suspected to be limiting performance of CdTe detectors have been traced to the furnace wall materials; installation of platinum wall liners is planned. Refinement of programs for the simulation of chemical reactions continued. A number of improvements were made to the fuel defect experiment data processing system. Operations of the MP Tandem Accelerator and the main site computing centre are summarized. (OST)

    A prototype pocket-sized gamma radiation warning dosimeter is being tested. The sorption of arsenic on CRNL soils stripped of oxide coatings is being studied to give an indication of the role of hydrous oxides in oxides in arsenic migration. The migration of iodide through fractured rock is being studied. Improvements have been made in source preparation and measurement techniques in the collaborative experiments on accelerator measurement of low levels of carbon-14. Work in radiation biology is continuing on induction of genetic changes in yeast by radiation and other agents, on the free radicals responsible for these changes, on photoproducts formed in DNA by ultraviolet radiation, on methods to study DNA damage and repair in irradiated human cells, on radiation sensitivity of cells from humans with various diseases associated with susceptibility to cancer, and on induction of cancers in rats by radiation in combination with environmental chemicals. Studies on radon and thoron daugther dosimetry were initiated in conjunction with a Nuclear Energy Agency Working Group. A procedure for the separation of 35S and 32p in bioassay was developed. (LL)

    International Nuclear Information System (INIS)

    Calculations have been made of the radiation doses received in the vicinity of a neutron source, taking into account the interactions of neutrons with concrete and the reflection of thermal neutrons from the body surface. Further calculations have been carried out on the leakage spectrum of fission neutrons through shields of polyethylene and iron. A new TLD dosimeter plaque is under development, and several models of a light-weight tritium-in-air monitor have been assembled. The design of an instrument for detecting plutonium in wastes has been completed. Studies have been initiated on the aquaculture of clams in warm fresh water. Studies on the neutralization of acid precipitation by soil minerals have been concluded. Cellulose is being separated from the wood of a tree which grew in the Inner Area of CRNL for tritium and carbon-14 analyses. Two-dimensional flow modelling has been attempted on an underground contaminant plume. Research continues into the nature of DNA damage and the repair of strand breaks; the repair process is being studied at radiation doses down to 250 rad. An experiment on the relative biological effectiveness of tritium beta rays as related to breast cancer in female rats has been started. The first details from the follow-up of past CRNL employees are available and show no major discrepancies in gross categories of causes of death. Dosimetric and metabolic models for calculating doses from internally deposited technetium have been reviewed. (L.L.)

    International Nuclear Information System (INIS)

    Highlights of work in health physics include investigation of electrochemical etching procedures, further studies of gels saturated with superheated liquid drops, development of a beta dose rate meter using a chopper-stabilized amplifier, and operational tests of dose distributions on workers exposed in high gradient fields. Work in environmental research has included development of a model (LEEM) of one-dimensional vertical mixing of heat in lakes, further studies of the influence of sediment-water interaction on movement of contaminants in surface waters, application of nuclear techniques to an analysis of borehole waters for measurement of pipe flows, and efforts to determine the scale dependence of dispersivity. Research activity in radiation biology centres around the effects of radiation on a variety of organisms. The principal sensitive target is believed to be DNA and work continues towards understanding the nature of the damage and the response of cells as they attempt to repair the injury. Biomedical research has focussed on the study of metal ion-amino acid complexes and assembling data bases for internal dosimetry calculations. Computer codes are being developed to establish standard models and evaluate specific contamination cases

  8. Progress report, Physics Division, October 1 to December 31, 1978

    International Nuclear Information System (INIS)

    Several experiments are in progress to measure parity violation in strong interactions. The g-factors of eight high-spin isomeric states in four gadolinium isotopes have been added to the previously determined spin and parity data. Existing data on neutron-capture M1 γ-ray widths have been analyzed to deduce the position and spreading width of the M1 giant resonance in heavy nuclei. Solutions to long-standing differences between experimental and theoretical values for the thermal neutron capture cross sections of 1H and 3He are being sought in the framework of a more complete meson exchange theory. The standards group has submitted a value to the Bureau International des Poids et Mesures (BIPM) in a major international comparison of the measurement of the activity of 134Cs. Development of the Fast Intense Neutron Source and the superconducting cyclotron continues. Preliminary design work is complete and component fabrication is underway for a preaccelerator suitable for accelerator breeder applications. Development is continuing on a multi-aperture duoPIGatron ion source with beam current and emittance suitable for a high current accelerator. In fertile-to-fissile conversion experiments at TRIUMF, the relative counting efficiencies of the β detectors used for proton beam monitoring and for neutron absorption rate measurement have been re-determined. Fusion studies included a preliminary study of anomalous energy loss mechanisms for high density relativistic electron beams ineracting with matter, and calculations to develop reliable neutronic evaluaton of fusion breeder blanket assemblies. Operations of the MP tandem accelerator and the main site computing facility are also summarized. (OST)

These technically oriented studies have a strong base in fundamental research in a variety of scientific disciplines, including molecular and cellular biology, biophysics, genetics, radiobiology, pharmacology, biochemistry, chemistry, environmental toxicology, and epidemiology. This research summary is organized into six parts. The first five parts reflect the Divisional structure and contain the scientific program chapters, which summarize the activities of the individual groups during the calendar year 1984 and the first half of 1985. To provide better continuity and perspective, previous work is sometimes briefly described. Although the summaries are short, efforts have been made to indicate the range of research activities for each group.

    1981-01-01

    Recent work in the fields of exobiology, the study of the possible characteristics of extraterrestrial life, and planetary biology, the study of life forms as a function of planetary conditions, is reviewed. Searches conducted for life on Mars by the Viking Landers and on Titan by Voyager 1 are considered, and the origin of life on earth is considered in relation to the question of the inorganic trace elements in living systems that are required for life. The question of the origin of terrestrial life from spores carried through the interstellar medium is examined, and the unlikelihood of the survival of such spores except within meteorites or dust particles is pointed out. Studies of organic molecules present in the interstellar medium are indicated as evidence that the conditions necessary for the formation of life can exist in various locations throughout the universe. Investigations of the molecular evolution of life on earth and of life under extreme conditions of heat, cold, drought and ultraviolet radiation, and of the organic compounds found in meteorites and comets are also discussed. The importance of a mechanism of heredity, such as terrestrial DNA, to the evolution of terrestrial and possible extraterrestrial life is pointed out.

These biological agents have been proven effective in RA patients with inadequate responses to synthetic disease-modifying antirheumatic drugs (DMARDs. Preventing joint damage is now the primary goal of RA treatment, and guidelines exist for the follow-up of joint abnormalities. Most biologic agents produced high clinical and radiological response rates in patients with established or recent-onset RA. Thus, for the first time, obtaining a remission is a reasonable treatment goal in RA patients. Factors that are crucial to joint damage control are: early initiation of DMARDs, use of intensive treatments including biological agents, and close monitoring of clinical disease activity and radiographic progression. However, some patients remain unresponsive to all available treatments and continue to experience joint damage progression. A major objective now is to identify patients at high risk for severe joint damage, in order to tailor the treatment regimen to their specific needs.Keywords: rheumatoid arthritis, radiographic progression, biologics

    International Nuclear Information System (INIS)

    The progress report on the Physical Sciences, Physics Division, is split into Accelerator Physics and Neutron and Condensed Matter Science Branch. The Accelerator Physics Group in collaboration with Fuel Channel Components Branch has undertaken a unique series of experiments to prove the feasibility of using high energy electron beams for out-reactor irradiation of bulk samples of pressure-tube materials. The Neutron and Condensed Matter Branch, has among other topics, been involved with the Sudbury Neutrino Observatory project. It is part of an international collaboration including Canada, United States, and the United Kingdom. The project involves the use of heavy water to detect particles called neutrinos that are emitted from the centre of the sun and from exploding stars. Results from the Molecular Physics program include a study of the differing structures of ice grown in an electric field. Atomic Ordering in the new intermetallics Al3 Ti-X was extensively investigated in the Materials Science program. In the theory program a code to calculate the multiphonon expansion of the incoherent scattering function was written and it was applied in the analysis of phonon density of states for amorphous and crystalline ice. Further calculations were made to develop improved understanding of superconductivity and a theory for the conductivity of vortex cores was proposed. 3 tabs., 15 figs

  16. Progress report of Physics Division. 1st October 1977 - 30th September 1978. Acting Division Chief - Mr. W. Gemmell

    International Nuclear Information System (INIS)

    Two main features influenced the year's activities: the Government's constraints on staffing and the Commission's views on research and development objectives. The reduction in staff numbers in Physics Division was by natural wastage, chiefly in the technical officer area. This has reduced operation of the reactor to a major extent and of the accelerator, both of which are now somewhat under-staffed and inadequately serviced. The second influence was the view of the Commission that research activities should move away from the more traditional areas of nuclear energy towards problems of the front end of the fuel cycle and the environment. Also, the Commission decided to place increasing emphasis on fusion and possibly on alternative energy studies. Neutron capture studies were continued, mainly in collaboration with Oak Ridge National Laboratory, Brookhaven National Laboratory and Bruyires-le-Chgtel and, to a lesser extent, the Australian universities, with the objective of improving our understanding of the capture mechanism and of seeking applications of the results and techniques developed in the neutron capture research. Results from the measurement of the 252Cf spontaneous fission neutron spectrum are now available in reasonably final form. other fission work was concerned with the shape of the fission barriers for the thorium isotopes and with confirming differences between the 0+ and 1+ resonances of 239Pu. Commercial acceptance of the delayed neutron method of analyzing ore samples for uranium continued to gain ground. There was interest in the possibility of a similar service for thorium and the advantages of nuclear techniques of analysis became more widespread. Several of these techniques (backscattering, proton induced X-ray emission (PIXE), fission track) were actively developed. The major restraint was unavailability of staff. Particularly interesting was the coloration produced by proton irradiation of natural fluorite crystals. This coloration

    The following sentences highlight some of the technical activities carried out during 1991. They illustrate the diversity of programs and technical work performed within the Analytical Chemistry Division. Our neutron activation analysis laboratory at HFIR was placed into operation during 1991. We have combined inductively coupled plasma mass spectrometry (ICP/MS) with a preparation procedure developed at the Argonne National Laboratory to measure ultra-trace levels of U, Pu, Np, and Am in body fluids, primarily urine. Much progress has been made over the last year in the interfacing of an rf-powered glow discharge source to a double-focusing mass spectrometer. Preliminary experiments using electrospray ionization combined with ion trap mass spectrometry show much promise for the analysis of metals in solution. A secondary ion microprobe has been constructed that permits determination of the distribution of organic compounds less than a monolayer thick on samples as large as 1 cm diameter. Fourier transform mass spectrometry has been demonstrated to be a highly effective tool for the detailed characterization of biopolymers, especially normal and modified oligonucleotides. Much has been accomplished in understanding the fundamentals of quadrupole ion trap mass spectrometry. Work with ITMS instrumentation has led to the development of rapid methods for the detection of trace organics in environmental and physiological samples. A new type of time-of-flight mass spectrometer was designed for use with our positron ionization experiments. Fundamental research on chromatography at high concentrations and on gas-solid adsorption has continued. The preparation of a monograph on the chemistry of environmental tobacco smoke was completed this year.

    presents major problems, i.e. thermodynamic non-equilibrium and the one-dimensional aspect of the code. Several promising lines of developments are in hand which, if successful, will remove these difficulties and will lead to a more versatile code. Fairly intensive and increasing use is being made of the PDP-11/10 as an input/output terminal with interactive facilities. This has been successfully used to follow, visually, the progress of loss of coolant accidents and to provide interactive least squares analysis. A variety of applied spectral unfolding problems have been identified and tackled with these interactive facilities. Information on the rainfall, run-off water and impurity concentration of runoff and spring water from White's tailings mound at Rum Jungle, is now becoming available from equipment installed there during the dry season. It is hoped that a self-consistent picture will emerge of water behavior, and that this will assist in understanding the pollution problem. Codes have been developed to determine air and water movement within the heap (author)

    International Nuclear Information System (INIS)

    The reactor MOATA is operating successfully at 100 kW with the higher available flux being much appreciated by all users. An uranium analysis service commenced and the various mining exploration companies are gradually availing themselves of it in an increasing fashion. The possible introduction of a similar service for neutron radiography is being explored following successful laboratory studies. Various other applications of nuclear science are under development. The revised safety assessment carried out for 100 kW operation of MOATA led to a more generalized study of self limited, non boiling power transients and in particular the maximum reactivity limit for these transients. This involved a re-examination of the SPERT non boiling transients and the prediction of their outcome in quantitative terms on purely physics considerations without resort to normalization. The indications are that a 10 second period transient in MOATA would give rise to a power transient which would be self limited to 100 . A possible experiment to test this prediction is under examination. Various physics aspects of MOATA operation were studied on a mockup of the reactor on the split table machine and the degree of understanding by staff of this reactor's behavior much improved. The safety assessment of the split table machine (Critical Facility) was completed and should shortly be available from the printer for submission to the new Licensing and Regulatory Bureau for authority to operate. ν-bar measurements for the various fissile elements are complete, but studies of neutron emission from the individual fragments produced during the spontaneous fission of 252Cf fission and the neutron energy spectrum of 252Cf fission neutrons are being undertaken to clarify some of the remaining discrepancies. Analysis of neutron capture cross section data obtained at Oak Ridge National Laboratory is continuing. Details of the analysis for some element studies are given. Progress has also been made

    The Instrumentation and Controls (IandC) Division of Oak Ridge National Laboratory (ORNL) performs basic and applied instrumentation and controls research, development and design engineering, specialized instrument design and fabrication, and maintenance services for instruments, electronics, and computers. The IandC Division is one of the largest RandD organizations of its type among government laboratories, and it exists as the result of an organizational strategy to integrate ORNL's instrumentation and controls-related disciplines into one dedicated functional organization to increase the Laboratory's expertise and capabilities in these rapidly expanding, innovative areas of technology. The Division participates in the programs and projects of ORNL by applying its expertise and capabilities in concert with other divisions to perform basic research and mission-oriented technology development. Many of the Division's RandD tasks that are a part of a larger ORNL program are of sufficient scope that the IandC effort constitutes a separate program element with direct funding and management responsibility within the Division. The activities of IandC include performance of an RandD task in IandC facilities, the participation of from one of many IandC engineers and scientists in a multidisciplinary team working in a specific research area or development project, design and fabrication of a special instrument or instrumentation system, or a few hours of maintenance service. In its support and maintenance work, the role of the IandC Division is to provide a level of expertise appropriate to complete a job successfully at minimum overall cost and time schedule---a role which involves IandC in almost all ORNL activities

  15. Progress report for 1978-87 of the Food Technology and Enzyme Engineering Division

    International Nuclear Information System (INIS)

    The salient features of the research and development (R and D) activities of the Food Technology and Enzyme Engineering Division of the Bhabha Atomic Research Centre, Bombay, during the decade 1978-1987 are summarized. The Division was a part of the erstwhile Biochemistry and Food Technology which was bifurcated in 1985. The main thrust of the Division's R and D work is directed towards the development of appropriate technologies for radiation preservation of agricultural produce in natural form for prolonged periods without any perceptible change in quality attributes. The suitable parameters have been evolved to apply radiation technology for: (1) arresting sprouting losses in turbers and bulbs, (2) controlling infestation of cereals, spices and ready to eat food items, by insects, microbial pests and pathogens and (3) controlling spoilage of sea foods, fruits and vegetables. It is remarkable to note that the data collected during wholesomeness and toxicological studies of various irradiated food products have been used by the Joint Expert Committee on Food Irradiation of WHO/IAEA/FAO to accord unconditional health and safety clearance to irradiation process using upto 10 KGy radiation doses. The products treated with gamma radiation within this limit do not require toxicological evaluation. The technique for poly-valent radio-vaccine infective diseases in farm animals have been standardized and a vaccine to prevent Salmonella infection in poultry is undergoing field trials in farms. The other activities of the Division are in the fields of enzyme technology, photosynthetic process, and toxicity and genotoxicity of food ingredients and additives. Lists of staff-members of the Division and their publications, their participation in various symposia, seminars, conferences etc. are appended. (M.G.B.)

    1984-06-01

    This report covers work done during FY 1983 by the staff of the Energy Division and its subcontractors and by colleagues in other Oak Ridge National Laboratory divisions working on Energy Division projects. The work can be divided into four areas: (1) analysis and assessment, (2) models and data systems, (3) research to improve the efficiency of energy use and to improve electric power transmission and distribution, and (4) research utilization. Support came principally from the US Department of Energy (DOE), the US Nuclear Regulatory Commission, and the US Department of Defense, but also from a number of other agencies and organizations. Analysis and assessment included work on (a) environmental issues, including those deriving from the preparation of environmental impact statements; (b) energy and resource analysis; and (c) emergency preparedness. The models and data systems area involved research on evaluating and developing energy, environment, and engineering simulation models and on devising large data management systems, evaluating user data requirements, and compiling data bases. Research on improving the efficiency of energy use was focused primarily on the buildings and electricity sectors. A major effort on heat pump technology, which includes both heat-activated and electrically driven systems, continues. An important aspect of all the work was research utilization. Since the Energy Division is doing applied research, results are, by definition, intended to solve problems or answer questions of DOE and other sponsors. However, there are other users, and research utilization activities include technology transfer, commercialization efforts, outreach to state and regional organizations, and, of course, information dissemination.

We have theoretically investigated the temperature dependent wavelength shift of the AWG depends on the refractive indices of the materials and the size of the waveguide. A thermalization of the AWG can be realized by selecting proper values of the material and structural parameters of the device. We have taken into account the increased number of transmitted channels within DWDM technique over a thermal planar AWG of hybrid materials. The thermal effects of different hybrid materials employed in the fabrication of AWG are studied deeply and parametrically for the good performance of such AWG.

    The reports from the three branches in Physics Division, Accelerator Physics, Neutron and Solid State Physics and Theoretical Physics, are each presented in separate sections. Each section features a topical review, highlighting in this report the use of high-temperature rf and microwave response of materials, magnetic excitations in hexagonal ABX3 materials, and meson exchange currents in nuclear beta decay. Noteworthy achievements in the Accelerator Physics program include the successful operation to design energy of the re-vaned RFQ1 accelerator enabling now an energy of 1250 keV. The ECR ion source has operated for greater than 75 hours without failure and has produced the 100 mA needed for the RFQ1 accelerator. The neutron scattering program was again hampered by the NRU Reactor being down for repair. The good news is that the reactor was brought back up to full power in December thus enabling experiments to begin again. Experiments earlier in the year were carried out at Oak Ridge (US), Riso (Denmark), National Institute for Standards and Technology (US) and the Rutherford-Appleton Laboratory (UK). A new high capacity, portable pumping system was commissioned replacing a fixed one that had become obsolete and allowing now greater use of environment control devices on all spectrometers. An analysis of double-charge exchange reactions in nuclei has been used to provide limits on the radius of the neutron halo in 11Li. The most up-to-date, complete and accurate tables of neutron scattering lengths and cross-sections have been completed. Continuous quality improvement (CQI) analyses were initiated for all the activities in Physics Division with the goal to enhance performance and provide better service to our many customers

    1985-05-01

    The primary responsibility of the Health, Safety, and Environment (HSE) Division at the Los Alamos National Laboratory is to provide comprehensive occupational health and safety programs, waste processing, and environmental protection. These activities are designed to protect the workers, the public, and the environment. Evaluation of respiratory protective equipment included the XM-30 and M17A1 military masks, use of MAG-1 spectacles in respirators, and eight self-contained units. The latter units were used in an evaluation of test procedures used for Bureau of Mines approval of breathing apparatuses. Analyses of air samples from field studies of a modified in situ oil shale retorting facility were performed for total cyclohexane extractables and selected polynuclear aromatic hydrocarbons. Aerosols generation and characterization of effluents from oil shale processing were continued as part of an inhalation toxicology study. Additional data on plutonium excretion in urine are presented and point up problems in using the Langham equation to predict plutonium deposition in the body from long-term excretion data. Environmental surveillance at Los Alamos during 1983 showed the highest estimated radiation dose from Laboratory operations to be about 26% of the natural background radiation dose. Several studies on radionuclides and their transport in the Los Alamos environment are described. The chemical quality of surface and ground water near the geothermal hot dry rock facility is described. Short- and long-term consequences to man from releases of radionuclides into the environment can be simulated by the BIOTRAN computer model, which is discussed brirfly.

    International Nuclear Information System (INIS)

    The work of the Division in the areas of solid state science, radiation, physical and analytical chemistry, and materials science during the quarter is described. Measurements of ion stopping power have emphasized the importance of axial symmetry and may be used to show the contribution of nuclear inelastic events to stopping processes. Enhancement of ion scattering at 180 degrees can occur even in the first few layers of a single crystal of gold implanted with heavy atoms. Agreement has been obtained between experimental and calculated rates for dechanneling of protons in gold. The rate of decomposition of HOI in aqueous solutions has been determined. The effects of radiation on dithiothreitol is being studied. Laser photochemistry work includes investigations of multiphoton dissociation and of laser-induced zirconium isotope separation. A method has been found for the preparation of oxygen gas samples for the determination of oxygen isotope ratios in water, and high-performance liquid chromatography has been applied to metals in ground water. Sputtered coatings of stainless steel on the surface of zircaloy fuel cladding reduce the oxidation rate in steam. A theoretically-based design equation for irradiation growth of pressure tubes has been developed. Studies on the effect of small strains on zircaloy-2 tubing show the need to avoid even small amounts of compressive deformation of calandria tubes

  1. Occupational health and environment research 1984: Health, Safety, and environmental Division. Progress report

    International Nuclear Information System (INIS)

    The primary responsibility of the Health, Safety, and Environment (HSE) Division is to provide comprehensive occupational health and safety programs, waste processing, and environment protection. Two supplied-air suits tested for their functional protection were considered to be unacceptable because of low fit factors. Respiratory protective equipment testing for the uS Air Force, Navy, and Army was performed during 1984. The laser aerosol spectrometer (LAS-X) has been shown to operate successfully for measuring and sizing aerosols used for quality assurance testing of high-efficiency particulate air filters used at DOE facilities. Radioanalyses for 239Pu and 241Am are presented for the complete skeletal parts of two persons. Air samples from work areas in a coal gasification plant in Yugoslavia show minimal concentration of organic vapors, amines, polynuclear aromatic hydrocarbons, and phenols. Aerosol characteristics of oil shale vapors and manmade vitreous fibers used in ongoing inhalation toxicology studies are presented. Epidemiologic studies of smoking patterns among Los Alamos employees reveal 24.3% smokers compared with the US rate of 32.5%. Environmental surveillance at Los Alamos during 1984 showed the highest estimated radiation dose to an individual at or outside the Laboratory boundary to be about 25% of the natural background radiation dose. Surveillance studies on water and sediment transport of radionuclides, depleted uranium, and silver are described. Bibliographic review of the rooting depth of native plants indicates that even many grass species will root to depths greater than the earth overburden depths to cover low-level radioactive waste sites

  2. Progress report - physical sciences - physics division - 1993 January 01 - June 30

    International Nuclear Information System (INIS)

    After significant organizational change for the Physics Division, there are now two groups: Neutron and Condensed Matter Science, and Nuclear Physics. Theoretical Physics Branch was disbanded. A topical review of work on high power proton linacs describes the historical development of high power ion linacs and the ion source development program from initiation to its completion in 1993. RFQ1 became the first particle accelerator to be driven by a klystrode-based rf system. The accelerator operated at 1.25 MeV and accelerated more than 50 mA of high quality beam. The equipment has been sent to Los Alamos National Laboratory and will be recommissioned as the Chalk River Injection Test Stand (CRITS). The laser plasma beatwave accelerator generating accelerating field gradients of up to 1.8 GeV/m and acceleration of an injected electron beam to at least 30 meV over a 1 cm distance. The high power CO2 laser beam was used to irradiate Zr-N6 pressure tube samples. The aim was to assess surface modifications particularly from shock hardening. Application of radiofrequency waves were used to investigate the properties of relevant materials, notably industrial ferrites. Chalk River participated in an international collaboration on measurement of dielectric properties of materials at high temperatures. A second topical review on neutron scattering and mineral physics deals with phase transitions in carbonate and in silicates. Dualspec is operating successfully. Modifications have been made to improve safety, reproducibility, angle control, calibration and sample analysis. Reviews from six programs: physics, molecular physics, material science, condensed matter theory, neutrino physics, and molecular dating and modelling are given. 1 tab., 17 figs

    This document is the last Progress Report for the Neutron and Condensed Matter Science Branch, at Chalk River Labs of Atomic Energy of Canada Limited. The materials science program continued to include measurements of stress as a major component, but the determination of phase diagrams for specific alloys was also a prominent activity. Studies were made of two types of unusual magnetic materials. The magnetic properties of several oxide pyrochlore were investigated and spin waves were measured in the magnetic semiconductor, chalcopyrite. The crystal structures of the deuterated anti fluorite were determined and the reorientation of the ammonium ion was refined in detail. Differential scanning calorimetry measurements were used to investigate whether spontaneous phase separation into chiral domains occurs for mixtures of DPPC of opposite chirality. A new Neutron Velocity Selector was commissioned.

    International Nuclear Information System (INIS)

    An improved assay unit for determining the amount of plutonium in wastes, has been designed. A recently-written computer program for processing thermoluminescence dosimeter (TLD) readings will permit each TLD to have its own sensitivity calibration. TLDs used in fingertip dosimeters have been replaced by thinner TLDs which measure beta-ray doses more accurately. The performace characteristics of a new prototype monitor for tritiated water vapour in air have been measured. Work has started on a long-term environmental impact assessment of the waste management areas. A more detailed examination of the geochemical factors determining waste arsenic migration in ground water flow systems has been initiated. Studies have continued on the combined effects of thermal and nutrient enrichment on the productivity of fresh water organisms. A preliminary study of the plutonium content of surface waters has been made to identify potential sites for research on actinide behaviour in the environment. The third phase of a long-term experiment on synergism in rats has been started to determine whether ionizing radiation in combination with certain environmental carcinogens, such as cigarette tar and other chemicals, would increase the risk of tumours as compared with that from the separate treatments. A study on the genetic effects of x-rays at low dose rates has been largely completed. Research is continuing on (a) the radiation-induced release of membrane-bound components from the bacterial cell wall, (b) the induction of genetic changes in yeast by carcinogenic chemicals, (c) radiation-induced tumours in rats, (d) identification of the effects of ionizing radiation and ultraviolet light on the DNA of living organisms, and (e) the radiation sensitivity of human skin cells from individuals with rare familial diseases associated with proneness to cancer development. In addition, a collaborative paper has been prepared in which the health effects of energy development were reviewed. (OST)

  8. Division of Waste Management, Production, and Reprocessing programs progress report for January--December 1976

    International Nuclear Information System (INIS)

    Development of the acid digestion process for treating combustible nuclear wastes has progressed to design and construction of the Radioactive Acid Digestion Test Unit (RADTU). Tests were continued in the nonradioactive Acid Digestion Test Unit (ADTU) in an effort to improve the performance of the system. Nitric acid consumption has been decreased from 8.8 to 4.5 kg HNO3/kg digested waste by adding the nitric acid deep below the liquid surface in the annular heating vessel instead of at the surface of the tray digester. A highly successful 70-hr continuous processing run was completed in the ADTU to confirm the operating experience in shorter runs and to test the use of air (instead of nitrogen) in the airlift pump. Initial studies were completed on fixation of acid digestion residue following recovery and drying. A variety of solidification and testing equipment was assembled to prepare and test immobilized waste products. Studies were continued on immobilization of salts and wet wastes. Salt residue-cement systems characterized include calcium sulfate, ferric sulfate, sodium sulfate, sodium nitrate, calcium chloride, and sodium chloride. Anion and cation exchange resin immobilization in cement has also been studied, as well as immobilization of sodium silicate in cement. A new program on Intermediate Level Liquid Waste (ILLW) Solidification was started with the purpose of developing and demonstrating immobilization technologies for liquid and particulate solid ILW within the fuel cycle. The four primary fuel cycle operations (reactors, spent fuel storage basins, fuel reprocessing plants, and MOX fuel fabrication plants) were reviewed and a list of sources and quantities of waste was formulated. The annual accumulation of radioactive waste materials at the six commercial waste burial sites was updated through 1976. The total accumulated volume at the end of 1976 was about 434,000 m3

  9. Progress report Chemistry and Materials Division, 1 April - 30 June, 1980

    International Nuclear Information System (INIS)

    By a combination of electrostatic and magnetic deflection it has been possible to examine the yield of ions scattered through 1800 from the surface region of a variety of solid targets. Progress has been made in establishing a basis for quantitative assay of multiple vacancy clusters around single solute atoms in dilute alloys. HF laser-induced decomposition of 2,2,2,-trifluoroethanol has been studied as a function of laser fluence. The oxidation of carbon monoxide adsorbed on the (111) crystal face of platinum has been investigated further. Vacuum pumping systems of the D/H mass spectrometers have been replaced with turbo-molecular pumping systems, reducing the HD+ background five-fold. Three iodine species, I-, I03-, and I04-, have been successfully separated and detected in aqueous solutions in the course of iodine specification studies. It has been shown that the occurrence of groups of grains with preferentially tangential basal poles serves to locate any radial hydrides at the inside surface of Zircaloy fuel cladding, but does not make any additional contribution to the susceptibility of the cladding to iodine induced stress corrosion cracking. The orientation relationships between oxide and metal on the (0001), (1120) and (1010) planes of zirconium single crystals show a different relationship for each of the principal planes. Further studies in the High Voltage Electron Microscope at AERE, Harwell confirm that electron irradiation produces only interstitial loops, and does not introduce -component dislocations in zirconium. The microtome has been improved to the point where layers of a ductile metal (zirconium) down to 70 nm can be reproducibly removed. (auth)

    Biologic drugs for the management of rheumatoid arthritis (RA) have revolutionized the therapeutic armamentarium with the development of several novel monoclonal antibodies, which include murine, chimeric, humanized, fully human antibodies and fusion proteins. These biologics bind to their targets with high affinity and specificity. Since 1998, nine different biologics have been approved by the US Food and Drug Administration (FDA) and European Medicines Agency (EMA) for the treatment of RA, and several others are in different stages of clinical trials. This field is in continuous evolution and new biologics are tested every year. Therefore a precise analysis is required in order to have a detailed and updated state of the art of this field. In this review, our main aim is to analyse all available biological therapies that are FDA and EMA approved for the treatment of RA and also those that are in clinical trials for the management of RA patients.

    Full Text Available The history of the idea of biological progress shows that it is not a selfexplanatory category, so a clear definition is required. Biological progress exists if: (1 “more progressive” is defined as “more complex” – in that case evolution is synonymous with progress, i.e. development from simple to complex, from homogeneous to heterogeneous; (2 we perceive the expression “more progressive” as more successful in relation to the environment, in these terms some groups in the history of life were more progressive because/so that they survived, while others were retrogressive or less progressive because/so that they died out; on the other hand, within their ecological niches, certain forms of life (species are perfectly adapted to their environment as long as it is stable (along these lines, mammals are no more progressive than bacteria; (3 we take the span or reach of a potential adaptation of populations as a measure (in which case differences exist. However, there is no active, innovative problem solving in relation to the environment either with plants or animals – only the variability mechanism / selection is in place, automatism, instinct. In the light of the above-mentioned biological criteria, man is the most complex living creature by his constitution (central nervous system, he is the least dependent on the environment and can be innovative in relation to the environment. Man is the only living creature capable of establishing an active relationship with the environment through his special tool – culture. Considering the level of organization and quantity of information, the mammal genome is more progressive than the bacterium genome, while the human genome comprises most information which makes man the most progressive living thing. We can talk about biological progress if we define progressiveness as advancement toward complexity of organisation, but sometimes the simplification of structure enables survival. It seems

    Turosov, V S

    1992-01-01

    Two aspects can be distinguished in multistage carcinogenesis: etiological one (every stage is induced by a specific for this stage agent) and morphobiological aspect (every stage is characterized by specific morphological, genetic and other properties). The schema of the multistage carcinogenesis is presented in which morphological stages (diffuse and focal hyperplasia, benign tumours, dysplasia, carcinoma in situ, various phases of malignant tumour progression) are placed against genetic alterations. L. Foulds concept of tumour progression is discussed with special emphasis on precancerous stages, possibilities of cancer development de novo, and independent progression of different tumour characters. The following types of carcinogenesis are listed on the basis of interrelationship between etiological and genetic factors: 1) carcinogenesis induced by genotoxic agents; a) one agent is acting at high dose and for a long time thus ensuring the activation of protooncogenes and all stages of tumour progression (initiation, promotion, various phases of malignant tumour); b) those acting during a very short time, however sufficient for developing the genetic program working automatically without further exposure to known carcinogens (irradiation in case of the atomic bomb explosion or effect of short-living alkylating agents): in this case there is no stage of promotion; 2) carcinogenesis by non-genotoxic carcinogens (their mode of action is still unclear, the only human example is carcinogenesis by hormones); 3) development of tumours in frane of the two (or three) stage carcinogenesis when every stage is provoked by its own etiological factor, no human examples are known as yet; 4) development of tumours due to the genetic mechanism making the organism highly susceptible to the minimal doses of carcinogens as is the case with skin cancer by ultraviolet light in patients with xeroderma pigmentosum, the genetic damage in itself has nothing to do with tumour formation; 5

    The first area of research focuses on track structure effects in neutron microdosimetry and nanodosimetry. This is an investigation of the effect of proton energy-loss straggling and the associated transport of energy by secondary electrons on neutron event-size distributions in small sites. Secondly, energy deposition spectra and their moments for fast neutrons are investigated. Using calculated charged particle initial spectra and slowing-down spectra the authors can calculate the energy deposition in spherical cavities. Lastly, an attempt was made to study the relation of neutron energy deposition calculations to biology and biophysical models.

    The initial MOATA safety assessment was based on data and calculations available before the advent of multigroup diffusion theory codes in two dimensions. That assessment is being revised and extended to gain approval for 100 kW operation. The more detailed representation obtained in the new calculations has resulted in a much better understanding of the physics of this reactor. The properties of the reactor are determined to a large extent by neutron leakage from the rather thin core tanks. In particular the effect of leakage on the coupling between the core tanks and on reactivity coefficients has been clarified and quantified. In neutron data studies, the theoretical fission product library was revised, checked against any experimental values and distributed to interested overseas centres. Some further nubar work was done vith much better neutron energy resolution, and confirmed our earlier measurements. A promising formulation of R matrix theory of nuclear interaction is expected to lead to simpler multilevel resonance parameter description. With large amounts of digital data being collected, dissplayed and used by theoreticians and experimentalists, more attention -was given to visual interactive computer displays. This interest is generating constructive proposals for use of the dataway now being installed between the Division and the IBM 360/50 computer. The study of gamma rays following the capture of keV neutrons continues to reveal new and interesting features of the physical processes involved. A detailed international compilation of the gamma rays emitted and their intensities is in progress. The work on nickel-68, amongst others, has enabled a partial capture cross section to be generated from the gamma ray parameters obtained by experiment. Much work still remains to be done, possibly at other establishments with more extensive facilities.

    A pilot-scale modified carbon source division anaerobic anoxic oxic (AAO) process with pre-concentration of returned activated sludge (RAS) was proposed in this study for the enhanced biological nutrient removal (BNR) of municipal wastewater with limited carbon source. The influent carbon source was fed in step while a novel RAS pre-concentration tank was adopted to improve BNR efficiency, and the effects of an influent carbon source distribution ratio and a RAS pre-concentration ratio were investigated. The results show that the removal efficiency of TN is mainly influenced by the carbon source distribution ratio while the TP removal relies on the RAS pre-concentration ratio. The optimum carbon source distribution ratio and RAS pre-concentration ratio are 60%and 50%, respectively, with an inner recycling ratio of 100%under the optimum steady operation of pilot test, reaching an average effluent TN concentration of 9.8 mg·L−1 with a removal efficiency of 63%and an average TP removal efficiency of 94%. The mechanism of nutrient removal is discussed and the kinetics is analyzed. The results reveal that the optimal carbon source distribution ratio provides sufficient denitrifying carbon source to each anoxic phase, reducing nitrate accumulation while the RAS pre-concentration ratio improves the condition of anaerobic zone to ensure the phosphorus release due to less nitrate in the returned sludge. Therefore, nitrifying bacteria, denitrifying bacteria and phosphorus accumulation organisms play an important role under the optimum condition, enhancing the performance of nutrient removal in this test.

  7. External irradiation facilities open for biological studies - progress in july 2005

    International Nuclear Information System (INIS)

    The Life Science Division of the Atomic Energy Commission is making an inventory of the various radiation sources accessible for investigation on the biological effects of ionizing radiation. In this field, a wide range of studies is being carried out at the Life Science Division, attempting to characterize the kind of lesions with their early biological consequences (on the various cell compartments) and their late biological consequences (deterministic or stochastic effects), in relation to the radiation type and dose, especially at low doses. Several experimental models are available: plants, bacteria, eukaryotic cells from yeast up to mammalian cells and in vivo studies, mostly on rodents, in order to characterize the somatic late effects and the hereditary effects. Due to the significant cost of these facilities, also to their specific properties (nature of the radiation, dose and dose rate, possible accuracy of the irradiation at the molecular level), the closeness is no longer the only criteria for biologists to make a choice. The current evolution is to set up irradiation infrastructures combining ionizing radiation sources themselves and specific tools dedicated to biological studies: cell or molecular biology laboratories, animal facilities. The purpose, in this new frame, is to provide biologists with the most suitable facilities, and, if possible, to change these facilities according to requirements in radiobiology. In this report, the basics of interactions of ionizing radiation with biological tissues are briefly introduced, followed by a presentation of some of the facilities available for radiobiological studies especially at CEA. This panorama is not a comprehensive one, new data will be included as they advance, whether reporting existing facilities or if a new one is developed. (authors)

    Full Text Available Graeme Jones, Erica Darian-Smith, Michael Kwok, Tania WinzenbergMenzies Research Institute, University of Tasmania, Tasmania, AustraliaAbstract: There have been substantial advances in the treatment of rheumatoid arthritis in recent years. Traditional disease-modifying antirheumatic drugs (DMARDs have been shown to have small effects on the progression of radiographic damage. This quantitative overview summarizes the evidence for biologic DMARDS and radiographic damage either alone or in combination with methotrexate. Two outcomes were used (standardized mean difference and odds of progression. A total of 21 trials were identified of which 18 had useable data. For biologic monotherapy, tocilizumab, adalimumab, and etanercept were significantly better than methotrexate, with tocilizumab ranking first in both outcomes while golimumab was ineffective in both outcomes. For a biologic in combination with methotrexate compared with methotrexate alone, most therapies studied (etanercept, adalimumab, infliximab, certolizumab, tocilizumab, and rituximab were effective at slowing X-ray progression using either outcome, with infliximab ranking first in both outcomes. The exceptions to this were golimumab (no effect on standardized mean difference and abatacept (no effect on odds of progression. This effect was additional to methotrexate; thus, the overall benefit is moderate to large in magnitude, which is clearly of major clinical significance for sufferers of rheumatoid arthritis and supports the use of biologic DMARDs in those with a poor disease prognosis.Keywords: rheumatoid, trials, meta-analysis, radiographs, biologic, disease-modifying antirheumatic drugs, DMARDs

    Several of the senior staff of the Division have assisted in the assessment of the tenders for the proposed Jervis Bay power station. This has involved studies on light water moderated reactor systems where our experience has been limited. Several of the questions raised by the tenders are considered important and effort on these topics will continue when the assessment is complete. Major effort, other than for the Jervis Bay Project, has been devoted to the improvement of facilities and the construction of the critical facility. Studies relevant to an improved understanding of MOATA have continued to support the proposed power uprating to 100 W. The increasing number of shielding (neutron and gamma) problems referred to the Division has resulted in the procurement of several specialised codes and data libraries. These are now operational on our IBM 360 computer, and several problems are being investigated

    Full Text Available As one of the five major global environmental problems, invasive species have posed serious threats to native ecosystems, public health, and regional economies. Although much progress has been madein the field of biological invasions research in China over the last decade, there are still large knowledge gaps. This paper reviews progress in the field of biological invasions research since 2000 as it relates to China, covering the diversity, colonization and immigration patterns of invasive species, mechanisms and ecological effects of biological invasions, and management and control of invasive species. In China, 529 invasive alien species have been identified, which originated primarily from South and North America, and the major taxa included terrestrial plants, terrestrial invertebrates, and microorganisms. We found a higher prevalence of invasive species in the eastern and southern provinces, compared to the western and northern provinces in China. This pattern is likely due to the differences in the level of economic development and environmental suitability between the two regions. Moreover, with further economic development, China may face more serious biological invasions in the future. These invasions of alien species are largely the combined results of the interactions between the intrinsic traits of these species along with resource opportunities and disturbances by human beings. Many mechanisms are responsible for successful invasionsof alien species, but phenotypic plasticity, adaptive evolution, enemy release, interspecific mutualism or commensalism, and new allelochemicals may be primary causative factors. Biological invasions in China have caused serious impacts on native ecosystems, including biodiversity and ecosystem services, alteration of biogeochemical cycles, threats to agricultural and forestry production, traffic and shipping, environmental safety, and public facilities. China has also made progress in the detection and

Patients control meets the standard management of patients in biological therapy. Results. The study shows that in the case of the resistance progressing when applying preparations of biological therapy, methotrexate is useful at a dose of 15-20mg/week for up to 6 months. The combined use of biologic therapy and methotrexate in the treatment of patients with psoriasis vulgaris, "escape effect" contributes to the marked regression of clinical symptoms and allows to control the process long enough, which is confirmed by the dynamics of the index PASI, BRS and DLQI. The combined method is highly safe, as evidenced by the lack of inhibition of hematopoiesis, the normal level of hepatic transaminases and serum creatinine, which greatly improves patient compliance in this type of therapy. Conclusion. The article presents the data of the combined application of biological medication therapy (ustekinumab and methotrexate for the treatment of patients with the common form of psoriasis vulgaris. In the case of the development of resistance of biological therapy recommended the appointment of methotrexate. The combined use of methotrexate and biologic therapy in the treatment of patients with psoriasis vulgaris contributes to marked regression of clinical symptoms and allows to control the process for a long time.

    2013-06-01

    This article describes the substance, structure, and rationale of a learning progression in genetics spanning kindergarten through twelfth grade (K-12). The learning progression is designed to build a foundation towards understanding protein structure and activity and should be viewed as one possible pathway to understanding concepts of genetics and ultimately protein expression, based on the existing research. The kindergarten through fifth grade segment reflects findings that show children have a rich knowledge base and sophisticated cognitive abilities, and therefore, is designed so that elementary-aged children can learn content in deep and abstract manners, as well as apply scientific explanations appropriate to their knowledge level. The article also details the LP segment facilitating secondary students' understanding by outlining the overlapping conceptual frames which guide student learning from cell structures and functions to cell splitting (both cell division and gamete formation) to genetics as trait transmission, culminating in genetics as protein expression. The learning progression product avoids the use of technical language, which has been identified as a prominent source of student misconceptions in learning cellular biology, and explicit connections between cellular and macroscopic phenomena are encouraged.

    All the mechanical and electronic components for the zero power splitable machine (the critical facility) arrived in excellent condition from France. Installation began and good progress was made on the mechanical side where the base and tables were successfully assembled and are being adjusted to meet the exacting specification. Power transients arising from the insertion of short reactivity steps were studied for the reactors, HIFAR, MOATA and the critical facility. Some effort was also devoted to the study of blowdown accidents in light water reactors and calculations of some Italian experiments were made successfully. The measurements of fast fission factor and initial conversion ratios for a range of natural uranium heavy water reactors were completed, and good progress is being made with neutron streaming in aluminium-water lattices. Many other investigators of this problem appear to have neglected or given insufficient attention to the case where the neutron beam is parallel to the plates. It is difficult to fit a cosine curve uniquely as coarse and fine features can not be separated. Previous analysis of the moisture content of soils and concrete by neutron scattering was successfully applied to obtain information on the variation of the moisture in large coal stacks as a function of time. This work was done in conjunction with Electricity Commission of N.S.W. Although a small Pu/Be source was found adequate for the above work, development continued on producing neutron pulses by means of a coaxial plasma focus device. Neutron pulses were produced regularly, but the output was variable; the fault was traced to breakdowns at the breech end of the device where restriking occurs. Although discrepancies of about 2% exist between V-bar for spontaneous fission of 252Cf as measured by the liquid scintillation method and by the Manganese bath method, this important quantity is being measured locally using the liquid scintillator method. Preliminary results suggest

    2003-01-01

    Plastid is one of the most important cellular organelles, the normal division process of plastid is essential for the differentiation and development of plant cells. For a long time, morphological observations and genetic analyses to special mutants are the major research fields of plastid division, but the molecular mechanisms underlying plastid division are largely unknown. Because of the endosymbiotic origin, plastid division might have mechanisms in common with those involved in bacterial cell division. It has been proved that several prokaryotic cell division genes also participate in the plastid division. Recently, the mechanisms of prokaryotic cell division have been well documented, which provides a valuable paradigm for understanding the plastid division mechanisms. In plants, the functional analyses of ftsZ, a key gene involved both in bacteria and plastid division, have established the solid foundation for people to understand the plastid division in molecular level. In this paper we will make a review for the research history and progress of plastid division.

    Filamentous fungi are remarkable organisms naturally specialized in deconstructing plant biomass and this feature has a tremendous potential for biofuel production from renewable sources. The past decades have been marked by a remarkable progress in the genetic engineering of fungi to generate industry-compatible strains needed for some biotech applications. In this sense, progress in this field has been marked by the utilization of high-throughput techniques to gain deep understanding of the molecular machinery controlling the physiology of these organisms, starting thus the Systems Biology era of fungi. Additionally, genetic engineering has been extensively applied to modify wellcharacterized promoters in order to construct new expression systems with enhanced performance under the conditions of interest. In this review, we discuss some aspects related to significant progress in the understating and engineering of fungi for biotechnological applications, with special focus on the construction of synthetic promoters and circuits in organisms relevant for industry. Different engineering approaches are shown, and their potential and limitations for the construction of complex synthetic circuits in these organisms are examined. Finally, we discuss the impact of engineered promoter architecture in the single-cell behavior of the system, an often-neglected relationship with a tremendous impact in the final performance of the process of interest. We expect to provide here some new directions to drive future research directed to the construction of high-performance, engineered fungal strains working as microbial cell factories. PMID:27226765

    1,3-propanediol is an important raw material in chemical industry. Microbial conversion of glycerol or glucose into 1,3-propanediol has been given much attention due to its renewable resource, mild reaction conditions, and other advantages. It is a challenge to efficiently separate 1,3-propanediol from a mixture of multiple components, such as 1,3-propanediol, 2,3-butanediol, water, residual glycerol, ethanol, macromolecules and salts, for the reason that 1,3-propanediol, glycerol and 2,3-butanediol are all very hydrophilic and have intense polarity. The conventional evaporation and distillation techniques used in the purification of 1,3-propanediol suffer from the problem of high energy consumption and low recovery. It makes the recovery of 1,3-propanediol from a fermentation broth become a bottleneck in industrial production. The down-stream processing of biologically produced 1,3-propanediol mainly includes the removal of protein, salts, water and other impurities. This paper analyze the research progress of these separation technologies and point out the developing direction worth further investigation. PMID:21650033

    Full Text Available This paper presents a study carried out with Biology teachers under training, and aimed at investigating how concept maps enabled meaningful learning. The work was motivated by the fact that future teachers presented difficulties learning various concepts. In this light, maps can be a valuable instrument for the diagnosis and assessment of learning, enabling better concept learning. Thus, during our pedagogical intervention, we have strived to identify the conceptual evolution of students, through the construction of concept maps before, during and after the study of a proposed theme. The qualitative analysis of the produced maps focused on the processes of teaching, learning and assessment. At this point, the goal was to investigate whether or not students were able to relate the concepts under study, according to the principles of progressive differentiation and integrative reconcilitation. This was done while searching for evidences of meaningful learning.The pedagogical intervention lasted for 45 hours (8 meetings, during which a Zoology topic, concept Elephants was studied at a State university of Brazil. The qualitative analysis of the maps created by the learners has shown, in 58% of the cases, that there was an evolution of the learnersʼ knowledge of the theme. Obtained results suggest that maps have an efficient functional action and help improve the professional profile under formation.

    Progress is reported on a broad and comprehensive series of biological experiments made under strictly controlled laboratory conditions to screen for possible effects of exposure to 60-Hz electric fields on small laboratory animals. Electric field strengths comparable to and exceeding those under existing and anticipated transmission line designs will be used. Dosimetry studies will complement the animal studies to establish the relationship between tissue dose and any observed biological effects. Information derived from this project will provide a better basis for evaluating potential hazards of exposure to 60-Hz electric fields and help define parameters to be studied in clinical evaluations on humans.

  11. Long-Term Progressive Degradation of the Biological Capability of Titanium

    Directory of Open Access Journals (Sweden)

    Hajime Minamikawa

    2016-02-01

    Full Text Available Titanium undergoes time-dependent degradation in biological capability, or “biological aging”. It is unknown whether the biological aging of titanium occurs beyond four weeks and whether age-related changes are definitely associated with surface hydrophilicity. We therefore measured multiple biological parameters of bone marrow-derived osteoblasts cultured on newly prepared, one-month-old, three-month-old, and six-month-old acid-etched titanium surfaces, as well as the hydrophilicity of these surfaces. New surfaces were superhydrophilic with a contact angle of ddH2O of 0°, whereas old surfaces were all hydrophobic with the contact angle of around 90°. Cell attachment, cell spread, cell density, and alkaline phosphatase activity were highest on new surfaces and decreased in a time-dependent manner. These decreases persisted and remained significant for most of the biological parameters up to six-months. While the number of attached cells was negatively correlated with hydrophilicity, the other measured parameters were not. The biological capability of titanium continues to degrade up to six months of aging, but these effects are not directly associated with time-dependent reductions in hydrophilicity. A full understanding of the biological aging will help guide regulatory improvements in implant device manufacturing and develop countermeasures against this phenomenon in order to improve clinical outcomes.

  14. Functionalization of carbon nanotube and nanofiber electrodes with biological macromolecules: Progress toward a nanoscale biosensor

    Science.gov (United States)

    Baker, Sarah E.

    The integration of nanoscale carbon-based electrodes with biological recognition and electrical detection promises unparalleled biological detection systems. First, biologically modified carbon-based materials have been shown to have superior long-term chemical stability when compared to other commonly used materials for biological detection such as silicon, gold, and glass surfaces. Functionalizing carbon electrodes for biological recognition and using electrochemical methods to transduce biological binding information will enable real-time, hand-held, lower cost and stable biosensing devices. Nanoscale carbon-based electrodes allow the additional capability of fabricating devices with high densities of sensing elements, enabling multi-analyte detection on a single chip. We have worked toward the integration of these sensor components by first focusing on developing and characterizing the chemistry required to functionalize single-walled carbon nanotubes and vertically aligned carbon nanofibers with oligonucleotides and proteins for specific biological recognition. Chemical, photochemical and electrochemical methods for functionalizing these materials with biological molecules were developed. We determined, using fluorescence and colorimetric techniques, that these biologically modified nanoscale carbon electrodes are biologically active, selective, and stable. A photochemical functionalization method enabled facile functionalization of dense arrays vertically aligned carbon nanofiber forests. We found that much of the vertically aligned carbon nanofiber sidewalls were functionalized and biologically accessible by this method---the absolute number of DNA molecules hybridized to DNA-functionalized nanofiber electrodes was ˜8 times higher than the number of DNA molecules hybridized to flat glassy carbon electrodes and implies that nanofiber forest sensors may facilitate higher sensitivity to target DNA sequences per unit area. We also used the photochemical method

    Directory of Open Access Journals (Sweden)

    Edna N. Lamsen

    2012-06-01

    Full Text Available The growing need to address current energy and environmental problems has sparked an interest in developing improved biological methods to produce liquid fuels from renewable sources. While microbial ethanol production is well established, higher chain alcohols possess chemical properties that are more similar to gasoline. Unfortunately, these alcohols (except 1-butanol are not produced efficiently in natural microorganisms, and thus economical production in industrial volumes remains a challenge. Synthetic biology, however, offers additional tools to engineer synthetic pathways in user-friendly hosts to help increase titers and productivity of these advanced biofuels. This review concentrates on recent developments in synthetic biology to produce higher-chain alcohols as viable renewable replacements for traditional fuel.
