    CER59SSK45.September 1959.Conducted for the Martin Company, Denver Division, Denver, Colorado through Colorado State University Research Foundation, Civil Engineering Section, Fort Collins, Colorado.This report presents an evaluation of the performance of a Pottermeter Model 2-353A. The original meter tested was found to give erratic results due largely to the formation of a vapor pocket at the stationary cone. The meter was redesigned by the Pottermeter Company and the results of tests of the revised meter showed improvement in performance characteristics. Tests for head loss and pressure distribution through the meter were also made and are reported herein.Under Martin contract no. F8-51390

    Evaluation of the performance of the Gulton Ultrasonic, Gentile Tube and Potter model 6-424 GLMD-5 flowmeters

    CER59FV11.June 1958.Conducted for the Martin Company, Denver Division, Denver, Colorado through Colorado State University Research Foundation, Civil Engineering Section, Fort Collins, Colorado.This report represents an investigation and evaluation of the performance of several types of flowmeters under simulated prototype conditions. Three types of flowmeters were tested: Gulton Ultrasonic, Gentile Tube, and Potter Model No. 6-424 GLMD-5. The Gulton Ultrasonic Meter on the basis of initial test results was found to be of faulty design, and was, therefore, excluded from further testing. Meter performance for changes in flow and fluid properties was studied. Changes in flow properties included both low and high backpressure intensities, and turbulence induced immediately upstream of the meter by means of a grid. Injection of air into the test line produced a change in the mass density of the fluid - - a fluid property. Meter sensitivity in recording discharge were also made using combinations of peizometric taps located at various positions along the boundary geometry. A comparison is made of the performance of the flowmeters under similar changes in flow and fluid properties

    Time-scarcity, ready-meals, ill-health and the obesity epidemic

    Get PDF
    In this 3-part paper, we firstly review the interaction of time-scarcity with food-choices, specifically ready-meals, and potential health consequences from their consumption. Secondly we review declared nutrients, in relation to the standard 30% of Guideline Daily Amounts, concluding that popular ready-meals from major UK supermarkets are currently nutritionally haphazard. Thirdly, we present a simple scheme to establish standards for nutritional composition of ready-meals: unless otherwise specified, any meal (the smallest unit of nutrition) as recommended to be eaten or as offered should provide 30%+10% of GDA for energy and pro rata for key nutrients (e.g. sodium, sat fat, vitamin C)

    Parental influences on adolescent fruit consumption : the role of adolescent self-efficacy

    Full text link
    The aims of this study were to examine whether adolescent self-efficacy mediates the associations between parental control, perceptions of the importance of healthy nutrition for child health and barriers to buying fruits and vegetables and adolescent fruit consumption using a theoretically derived explanatory model. Data were drawn from a community-based sample of 1606 adolescents in Years 7 and 9 of secondary school and their parents, from Victoria, Australia. Adolescents completed a web-based survey assessing their fruit consumption and self-efficacy for increasing fruit consumption. Parents completed a survey delivered via mail assessing parental control, perceptions and barriers to buying fruit and vegetables. Adolescent self-efficacy for increasing fruit consumption mediated the positive associations between parental control and perceptions of the importance of healthy nutrition for child health and adolescent fruit consumption. Furthermore, adolescent self-efficacy mediated the negative association between parental barriers to buying fruits and vegetables and adolescent fruit consumption. The importance of explicating the mechanisms through which parental factors influence adolescent fruit consumption not only relates to the advancement of scientific knowledge but also offers potential avenues for intervention. Future research should assess the effectiveness of methods to increase adolescent fruit consumption by focussing on both improving adolescents&rsquo; dietary self-efficacy and on targeting parental control, perceptions and barriers. <br /

    Father–Daughter Bonds: A Comparison of Adolescent Daughters’ Relationships with Resident Biological Fathers and Stepfathers

    Objective: To investigate whether the interpersonal dynamics of closeness are different in stepfather–stepdaughter versus father–daughter relationships during adolescence. Background: Establishing a general process model of the relational factors contributing to greater closeness between fathers and daughters is a preliminary step toward examining variations in such processes. Method: The data were from the National Longitudinal Study of Adolescent to Adult Health (ADD Health), a nationally representative sample of adolescents. Respondents were female adolescents who were living with either a biological father (n = 1,881) or stepfather (n = 273) and reported on the availability and involvement of their (step)fathers, as well as the communication and closeness in their relationship with him. Results: Involvement and communication were predictors of closeness in both types of relationships, however, communication was a stronger predictor of closeness between stepfathers and stepdaughters. For adolescent girls living with a stepfather, greater involvement with their stepfathers was associated with greater closeness to their non-resident biological fathers. The length of the relationship between stepfathers and stepdaughters was not associated with levels of closeness. Conclusions: Overall, these findings suggest that stepfather–stepdaughter relationships reflect similar interpersonal dynamics as father–daughter relationships but that establishing and maintaining these relationships through meaningful communication may be particularly important for stepfathers and stepdaughters. Implications: Practitioners working to help stepfamilies build stronger relationships may want to stress that investing in shared activities and maintaining meaningful communication can be particularly important for establishing and maintaining positive relationships between stepfathers and stepdaughters
