    Preliminary science results of the Voyager 1 encounter of the planet Saturn are reported. On August 22, 1980, the spacecraft was 109 million km (68 million mi) from Saturn. Closest approach to Saturn took place on November 12, at 3:46 p.m. (PDT), when the spacecraft passed 126,000 km (78,000 mi) from the cloud tops. Measurements of the atmosphere, wind speed, radiation, six surrounding rings, and the planet's old and newly found satellites were recorded. The encounter ended December 15, 1980. The spacecraft took more than 17,500 photographs of Saturn and its satellites

    Effects of an Exercise Program on Mentally Impaired Older Adults in a Long-Term Care Facility

    This study is a contradistinction to research which assesses the effects of exercise only on older adults who are in good health. This study examined the effect of an eight-week exercise program on 24 individuals with mental impairments, primarily Alzheimer\u27s disease and dementia. Subjects were volunteers who resided in a long-term care skilled nursing facility (SNF). Group composition was 7 males, mean age 83.29 and 17 females, mean age 88.71; mental and physical function levels varied from supervised to total dependence of care. Six variables were tested: right and left shoulder flexibility, right and left hand grip strength, modified sit and reach flexibility, and life satisfaction. Subjects participated in a low intensity exercise program three days a week, with physical variables measured weekly. The data were analyzed in two stages. Only aggregate data were analyzed each week because group composition was inconsistent at any given point at time of measurement, principally due to participants\u27 handicapping conditions and current physical health, but also due to participants\u27 occasional refusal to participate on a given day. After the analysis of aggregate data is reported, individual subject case studies are presented, a necessity due to the population and participation rates. Results indicate that performance on physical variables using a means and standard deviation comparison to charting weekly progress did not show significant improvement. Pre- and posttests of right and left shoulder flexibility, right and left grip strength, and modified sit and reach were computed using a paired t-test. Significance was reached only for right shoulder flexibility t = 1.92, p = 3˘c\u3c.005. A life satisfaction assessment was administered as a pre- and posttest for the exercise program. Not all subjects were assessed due to cognition limitations; however, all but one of those assessed showed improvement in perceived life satisfaction (t = 8.91, p 3˘c\u3c.001). Results suggest that physical functions of flexibility and strength can improve in people with Alzheimer\u27s disease and dementia; however, more research is needed to determine possible contributions of physical exercise to cognitive functioning in individuals with progressive cognitive impairments. Additionally, longitudinal research may provide information to determine if physical exercise has a preventative or postponing effect on the characteristics of Alzheimer\u27s disease and dementia

    The Take Care - Use Antibrotics Responsibly® program is an antimicrobial resistance and use educat1on and awareness program for pork producers. The program is based on principles and guidelines intended to minimize the development of antimicrobial resistance whrle maximizing animal health The program was developed by the National Pork Board, but veterinarians are key in the delivery of the program on farm. Since there are many factors that contribute to the amounts and types of antimicrobrals used on farm it was decided that the best way to measure program effectiveness was through measurement of changes in the attitude and behaviors of program particrpants

    UManSysProp: an online facility for molecular property prediction and atmospheric aerosol calculations

    Abstract. In this paper we describe the development and application of a new web based facility, UManSysProp (http://umansysprop.seaes.manchester.ac.uk), for automating predictions of molecular and atmospheric aerosol properties. Current facilities include: pure component vapour pressures, critical properties and sub-cooled densities of organic molecules; activity coefficient predictions for mixed inorganic–organic liquid systems; hygroscopic growth factors and CCN activation potential of mixed inorganic/organic aerosol particles; absorptive partitioning calculations with/without a treatment of non-ideality. The aim of this new facility is to provide a single point of reference for all properties relevant to atmospheric aerosol that have been checked for applicability to atmospheric compounds where possible. The group contribution approach allows users to upload molecular information in the form of SMILES strings and UManSysProp will automatically extract the relevant information for calculations. Built using open source chemical informatics, and hosted at the University of Manchester, the facilities are provided via a browser and device-friendly web-interface, or can be accessed using the user's own code via a JSON API. In this paper we demonstrate its use with specific examples that can be simulated using the web-browser interface. </jats:p
