    Precise flow measurement is a critical part of many industries including industrial, hydropower, petroleum, nuclear, and water/wastewater. Lengthy upstream piping is required for many flowmeters to obtain accurate results. Due to piping constraints, sub- optimal flow meter installations can occur. One of these conditions is the installment of a flow meter in close proximity downstream of a double elbow out of plane (DEOP). A DEOP can cause swirl to form in the flow and can cause inaccurate metering results due to the non-uniform flow and pressure conditions. This study investigated the effect of installing a differential pressure producing wedge flow meter downstream of a DEOP on the flow measurement. Computational Fluid Dynamics (CFD) was used for this study in conjunction with physical testing

    Rising to the Top: Career Progression of Women Senior-Level Student Affairs Administrators

    Women account for over half of the populations of enrolled students and employed staff and administrators in higher education. In student affairs, women current accounts for over 60% of employees at the entry and mid-levels of administration, but less than half of all senior-level executive positions are filled by women. Furthermore, the majority of the women in senior-level student affairs administrative roles work at two-year institutions; doctoral granting research intensive universities have the lowest numbers of women student affairs professionals in senior-level positions. The career pathway to advance from entry-level to senior-level positions is unclear, and as a result, many women are remaining stagnant at the mid-level without a clear understanding of how to advance. The purpose of this study was to gain an understanding of how women professionals entering the field of student affairs in public research universities can chart a career pathway from their entry point to senior-level student affairs administrator positions. Because the numbers of female students and women in student affairs administration is continuing to grow, it is important that women are equally represented at the senior-levels at the top institutions in the U.S. Five current senior-level student affairs administrators, holding jobs at public four-year doctoral granting research universities in two states in the south central region of the U.S. were the participants for this study. Through purposeful sampling, the participants were identified to engage in this qualitative comparative case study inquiry. Various methods of data collection were used including: face-to-face semi-structured interviews (the primary source of data), document collection, and journaling. The research questions for this inquiry encompassed three broad inquiries including: (a) the reason female senior-level student affairs administrators choose to enter and remain in the field of student affairs, while attempting to chart a career pathway to senior-level positions at public four-year doctoral granting research institutions; (b) the experiences of women senior-level student affairs administrators, and how these experiences impacted their successful advancement to their current roles; and (c) advice for aspiring women senior-level student affairs administrators. The findings suggested that women can expect to experience both positive and negative encounters that will affect their career progression. The participants provided insight and advice for women in student affairs who aspire to become senior-level administrators that incorporated the importance of building a strong professional network of colleagues, embracing and leading change, and continuing education and professional development. Women must be intentional in creating a meaningful and rewarding career in student affairs and play a major part in developing their pathway to the top

    Barriers and facilitators experienced by osteopaths in implementing a biopsychosocial (BPS) framework of care when managing people with musculoskeletal pain – a mixed methods systematic review

    BACKGROUND: Clinical practice guidelines commonly recommend adopting a biopsychosocial (BPS) framework by practitioners managing musculoskeletal pain. However, it remains unclear how osteopaths implement a BPS framework in the management of musculoskeletal pain. Hence, the objective of this review was to systematically appraise the literature on the current practices, barriers and facilitators experienced by osteopaths in implementing a BPS framework of care when managing people with musculoskeletal pain. METHODS: The following electronic databases from January 2005 to August 2020 were searched: PubMed, CINAHL, Science Direct, Google Scholar, ProQuest Central and SCOPUS. Two independent reviewers reviewed the articles retrieved from the databases to assess for eligibility. Any studies (quantitative, qualitative and mixed methods) that investigated the use or application of the BPS approach in osteopathic practice were included in the review. The critical appraisal skills program (CASP) checklist was used to appraise the qualitative studies and the Mixed Methods Appraisal Tool (MMAT) was used to appraise quantitative or mixed methods studies. Advanced convergent meta-integration was used to synthesise data from quantitative, qualitative and mixed methods studies. RESULTS: A total of 6 studies (two quantitative, three qualitative and one mixed methods) were included in the final review. While two key concepts (current practice and embracing a BPS approach) were generated using advanced meta-integration synthesis, two concepts (barriers and enablers) were informed from qualitative only data. DISCUSSION: Our review finding showed that current osteopathic practice occurs within in the biomedical model of care. Although, osteopaths are aware of the theoretical underpinnings of the BPS model and identified the need to embrace it, various barriers exist that may prevent osteopaths from implementing the BPS model in clinical practice. Ongoing education and/or workshops may be necessary to enable osteopaths to implement a BPS approach

    DFT and experimental investigations on the photocatalytic activities of NiO nanobelts for removal of organic pollutants

    NiO nanobelts synthesized using the hydrothermal method are explored for photocatalytic degradation of organic pollutants like RhB, MO, MB, and CV. The XPS analysis confirmed the formation of the stoichiometric NiO nanobelts. Few micrometer long cubic crystalline NiO nanobelts of the average thickness of ∌75 nm delivered a bandgap of 4.07 eV. The FTIR studies revealed that the mesoporous NiO nanobelts delivered stable photocatalytic activities after controlled irradiation under a xenon lamp. The kinetic studies showed the 79.1, 82.7, 76.7, and 89% degradation of MO, MB, CV, and RhB after 140 min at the rate constants (k) of 0.007, 0.008, 0.009, and 0.012 min−1, respectively. Complementary first-principles Density Functional Theory (DFT) and scavenging studies revealed the chemical picture and influence of the , and photogenerated from NiO nanobelts in the photocatalytic degradation of organic dyes. These studies corroborate the use of the NiO nanobelts in the stable and eco-friendly photocatalytic degradation activities of a wide range of organic pollutants

    Small Heat Exchanger ORNL No. I, type SHE No. 2, was removed from test stand B after 2071 hours of operation; 1041 hours were under 4 T conditions. The heat exchanger contatned 20 Inconel tubes having an outside diameter of 0.25 in. and a wall thickness of 0.025 in. The outside of these tubes was exposed to the fluoride mixture NaF contained NaK (44% Na--56% K). During o degradation t T conditions, the fluoride temperature entering the heat exchanger was 1310 tained F and on leaving was 1235 tained F. The temperature of the NaK entering the heat exchanger was 1050 tained F and at the exit was 1290 tained F. During isothermal operation, the temperature of both the NaK and fluoride circuits was 1300 tained F. Thirtysix termperature transitions from isothermal to o degradation t T conditions were made during the course of operation. An examination of the resistance heater used in conjunction with this heat exchanger also was made: the results are reported. (auth

    We report on a new analysis of neutrino oscillations in MINOS using the complete set of accelerator and atmospheric data. The analysis combines the nu(mu) disappearance and nu(e) appearance data using the three-flavor formalism. We measure vertical bar Delta m(32)(2)vertical bar = [2.28-2.46] x 10(-3) eV(2) (68% C.L.) and sin(2)theta(23) = 0.35-0.65 (90% C.L.) in the normal hierarchy, and vertical bar Delta m(32)(2)vertical bar = [2.32-2.53] x 10(-3) eV(2) (68% C.L.) and sin(2)theta(23) = 0.34-0.67 (90% C.L.) in the inverted hierarchy. The data also constrain delta(CP), the theta(23) octant degeneracy and the mass hierarchy; we disfavor 36% (11%) of this three-parameter space at 68% (90%) C.L

    Mass Dependence of M3Y-Type Interactions and the Effects of Tensor Correlations

    Get PDF
    The mass dependence of the M3Y-type effective interactions and the effects of tensor correlations are examined. Two-body nuclear matrix elements are obtained by the lowest order constrained variational (LOCV) technique with and without tensor correlations. We have found that the tensor correlations are important especially in the triplet-even (TE) and tensor-even (TNE) channels in order to reproduce the G-matrix elements obtained previously. Then M3Y-type potentials for inelastic scattering are obtained by fitting our two-body matrix elements to those of a sum of Yukawa functions for the mass numbers A=24, A=40 and A=90.Comment: 13 pages, 6 table
