[en] Previously we have demonstrated an increase during midlactation in ¹⁰⁹Cd adsorption and increased retention by the duodenum, kidney, and mammary tissue of mouse dams receiving environmental levels of cadmium/¹⁰⁹Cd via drinking water, with little change in ¹⁰⁹Cd retention in liver and jejunum compared to nonpregnant controls. Results are reported here of a study of cadmium deposition during midlactation as associated with induction of metallothionein (MT). A cadmium/hemoglobin (Cd/Hb) assay and radioimmunoassay for MT which measures heat-stable cadmium binding capacity in tissues was used to determine MT concentrations in fractions of kidney, liver, duodenum, and jejunum from female mice. Both assays demonstrated clear lactation-induced increases in MT concentrations in liver, kidney, and duodenum, with MT concentrations falling rapidly to control levels after weaning. 4 refs., 1 tab

[en] Neutrino-oscillation studies using reactor sources can be made much more sensitive if the nu spectrum from the reactor is known. The fission of a heavy nucleus such as Cf or U creates neutron-rich nuclei so far from the valley of stability that their beta-decay spectra are not known. Thus a model must be employed to predict the overall beta-decay spectrum and the attendant nu spectrum. In order to test the reliability of the procedure in use the beta spectrum of the fission fragments following ²⁵²Cf fission is being measured to an accuracy of 3% in shape and 5% in total yield. An actively-collimated, flat-field beta spectrometer is used

[en] Results are reported of a study conducted to test the hypothesis that increases in cadmium deposition during midlactation are caused by an induction of the metal-binding protein, metallothionein (MT). A cadmium/hemoglobin (Cd/Hb) assay for MT (which measures heat-stable cadmium binding capacity in tissues) was used to determine MT concentrations in the heat-treated supernatant fractions of kidney, liver, duodenum, and jejunum from five groups of B6CF1/ANL female mice. Portions of the same supernatants were also analyzed for MT by radioimmunoassay (RIA). Results show that metallothionein (or an MT-like cadmium-binding protein) increases in concentration in liver, kidney, and duodenum of mouse dams during lactation and decreases to levels found in nonpregnant controls by 5 days after weaning. They have evidence that the MT that appears in the liver of midlactating mice exists in two forms, a native form that chromatographs with a Ve/Vo = 1.6 and reacts strongly with MT antibody, and a second form that appears with heating or storage in the freezer (data not shown), reacts less strongly with MT antibody, and chromatographs with a lower apparent molecular weight (Ve/Vo = 2.2)

[en] A summary is presented of the conclusions reached by Nuclear Physics Group on the subject of nuclear physics with neutrinos to be addressed with the planned neutrino facility. In other material provided for the workshop details of the reactions are considered and expanded upon, and more complete references to previously published work are given. This section distills this material and states in summary form the conclusions reached at this time. There are many examples of exclusive nuclear neutrino reactions that test specific parts of the electroweak current. The primary use of nuclear targets, as opposed to the nucleon, is likely to be this ability to select or filter out specific pieces of the interaction. Two exceptions, however, come to mind: (1) it will be of interest to demonstrate the nuclear coherence seen in elastic neutrino scattering, and likely the ⁴He case is the one favored; and (2) there may be a time when questions of axial-vector, meson-exchange current effects (many-body nuclear effects) can be addressed, perhaps in the case of deuteron-neutrino disintegration. The specific priorities we see for nuclear physics with neutrinos are listed

[en] In order to allow for high energy colliding beams with Fermilab accelerators it is necessary to provide beams which circulate counterclockwise in the Main Ring tunnel. A new extraction area has been designed and a tunnel to the main ring constructed. This transfer line to the main ring uses only small bends to accept (normal) counterclockwise circulating booster beam and create counterclockwise main ring beam. 5 refs

[en] The movement in semiconductor fabrication towards 'islands of automation', combined with the high cost of maintaining installed capital equipment, demands the optimization of implanter utilization. Presently, skilled process engineers are required to regularly setup and adjust implanter parameters. Any reduction in the number of production hours devoted to ion beam implanter setup or recalibration after a species change would represent substantial improvements in both manpower and equipment utilization.

[en] Since March 1978 the Fermilab Booster has operated with H;sup -; multiturn charge exchange injection. A record number of protons per Booster cycle has been injected and accelerated to 8 GeV. The details of the injection system are discussed as well as the Booster performance and the reliability of the method. 11 refs

[en] The use of empirical models for On-Line Monitoring (OLM) of safety critical instrumentation for calibration reduction has been investigated for over a decade. To help support the regulatory review of possible license amendments, a series of three NUREG/CRs are being developed, The first volume in this series, entitled NUREG/CR-6895 'Technical Review of On-line Monitoring Techniques for Performance Assessment Volume I: State-of-the-Art', offers a general overview of current sensor calibration monitoring technologies and their uncertainty analysis, a review of the supporting information necessary for assessing these techniques, and a cross reference between the literature and the requirements previously outlined by the NRC. Volume II, 'Theoretical Issues', presents an in-depth theoretical study and independent review of the most widely used OLM techniques. It includes a presentation of the theory and further explanation of the assumptions inherent in empirical models and uncertainty quantification techniques. The third and final volume; 'Limiting Case Studies', presents the results of applying OLM models to a wide variety of plant data. Specifically, Volume III summarizes six case studies investigating the effects of model development and assumptions on model performance and offers recommendations for identifying and handling these limiting cases. This paper discusses the six cases studies. Although this study is not an exhaustive review of the many issues in OLM system development, it provides a base set of considerations which must be accounted for and a method for testing these considerations with other model architectures.

[en] General features of the inclusive hadroproduction of muon pairs of mass greater than 1.5 GeV/c² are shown. For incident π^-, the data extend up to M = 5.7 GeV/c² (i.e. M²/s approximately 0.4). The scaling cross section M³dsigma/dM for π^-N reaction is much flatter than that for pN reactions and exceeds the latter by two to three orders of magnitude at large M²/s. (Auth.)

[en] Measurements have been made of relative production cross sections of the J/psi by π^+-, K^+-, p and anti p at 39.5 GeV/c incident on copper. J/psi production rates from π^-, K^- and anti p are similar. The J/psi relative particle/anti-particle production cross sections for x > 0 are sigma(π⁺)/sigma(π^-) = (0.87+-0.14), sigma(K⁺)/sigma(K^-) = (0.85+-0.5) and sigma(p)/sigma(anti p) = (0.15+-0.08). The small p/anti p cross section ratio disagrees with models of J/psi production by gluon amalgamation. (Auth.)
