Cooling due to collisions between hydrogen molecules and helium atoms

This study concerns the cooling that occurs in molecular clouds. The contribution to the cooling in these clouds by collisions between hydrogen molecules and helium atoms was investigated. The semi-classical method was used to calculate the rate coefficients for all He-induced H2 ro-vibrational transitions, and these were compared with previous quantum mechanical calculations. The steady state ro-vibrational level populations were found and used to compute the cooling function over a range of temperatures and densities. The time required to reach steady state is discussed, and a comparison is made of the results to corresponding values in thermodynamic equilibrium. The cooling function is compared to a previous quantum mechanical calculation. The suitability of the semi-classical method is discussed

Please consult print copy in Library.This thesis is a case study of the development of the National Cervical Screening Programme policy. The aim of the study was to identify and describe the political, social and ideological factors which may have influenced the National Cervical Screening Programme policy. The policy-makers included community or consumer participants as well as professionals. This relatively unique feature of community involvement was also a focus of study. The study involved a literature search and review as well as interviews with key informants. Cervical screening on a population basis was trialled as far back as the 1960s at the same time that Professor Green was questioning the efficacy of early treatment of cervical abnormalities. Green's controversial research resulted in a Royal Commission of Inquiry which recommended the establishment of a population based national cervical screening programme. The political, social and ideological context in which the National Cervical Screening programme policy was developed is described and interpreted. It is concluded that the National Cervical Screening Programme policy was adopted by the Government as a means to ameliorate the crisis of legitimation which was evident during the 1980s. It is further concluded that community or consumer participation in policy development is a highly complex issue requiring further study. Consumer representation is particularly problematic as consumer policy-makers require considerable skills, the acquisition of which may cause them to become less representative of the public whose voice they are intended to be

Ocean color algorithm for remote sensing of chlorophyll

An algorithm for the remote detection of chlorophyll a in the ocean was tested during a Nantucket Shoals experiment conducted by NASA. A set of Multichannel Ocean Color Sensor (MOCS) data selected from one flight for each of the two altitudes flown was used to calibrate the algorithm for chlorophyll a concentration. The equations were then applied to all unsaturated MOCS data collected during the 8-day experiment to generate contour maps of chlorophyll a concentration over the shoals. One additional flight was conducted away from the shoals both on and off the Continental Shelf. Although no solar elevation or environmental corrections were made to the original conversions, the equations in these tests determined chlorophyll a concentrations to an accuracy better than 1.0 micron g/L despite the fact that the solar elevation varied between 20 deg and 56 deg during the data collection periods of the experiments

Application of Boron Isotopes to Constrain the Depositional Environment of the Precursors to Proterozoic Granulite-Facies Borosilicate Paragneisses, Larsemann Hills, Antarctica

Intellectual Merit. Major challenges in understanding high P-T granulite facies terranes are identifying the original protolith rocks and the tectonic environment in which they were originally deposited. This project focuses on granulitic gneisses exposed in the Larsemann Hills, Prydz Bay (East Antarctica). These rocks are considered to be metasediments (paragneisses), but, despite more than 20 years of intense study, the tectonic framework of deposition of the original rocks is still debated. However the origin of these rocks has important implications for determining the assembly of the ancient Gondwana continent. The unique B-rich character of the rocks offers potential insight into the original environment of deposition as well as the subsequent tectonic and metamorphic history. Because of its relative affinity for aqueous fluids and silicate melts, B typically is strongly depleted in such high-grade metamorphic rocks; the fact that some remain extremely B-rich (with up to 20% tourmaline) is highly enigmatic. In this study, B isotopic composition will be used to investigate the initial cause of boron enrichment as well as processes that redistribute boron during metamorphism. Boron has two isotopes that differ significantly in atomic weight: 10B and 11B. As an example of the discriminating power of B isotopic measurements, non-marine evaporates are characterized by unusually depleted in 10B relative to 11B, whereas typical marine sediments have high 11B/10B (i.e., inherited from seawater). B isotopic composition will be measured in situ using secondary ion mass spectroscopy (SIMS) of tourmaline and other borosilicate minerals from samples obtained in the Larsemann Hills during the 2003-2004 field season. B isotope data will be used to constrain compositions of the protolith rocks, and these data combined with results of petrologic studies to constrain the effects of metamorphism, anatexis, devolatilization leading to formation of B-rich gneisses. By analogy with similar rocks from Broken Hill, Australia, he proposed research will test the hypothesis that the Larseman Hills protolith originated as B-rich non-marine evaporates, that the original B was partly mobilized by submarine hydrothermal fluids that reacted with clastic sediments and volcaniclastic rocks to form tourmaline-bearing rocks (the protolith), and that the B-rich character of the gneisses was preserved via preservation of tourmaline and other borosilicate minerals during metamorphism and anatexis.Broader Impacts. The project will support one graduate student, who will analyze borosilicate and associated minerals in the Larseman Hills gneisses as a MA thesis project. This student will learn how to (1) use the electron microprobe to measure chemical composition, (2) become acquainted with measurement of lithium, beryllium and boron with the ion microprobe, (3) relate chemical composition to geologic environment, (3) develop reactions based on chemical and textural data (4) present her results orally before her peers, and (5) write a scientific paper for publication in a peer-reviewed journal

Boron-Bearing Kornerupine from Fiskenaesset, West Greenland: A Reexamination of Specimens from the Type Locality

In 1884, Lorenzen proposed the formula MgAI2SiO6 for his new mineral kornerupine from Fiskenæsset and did not suspect it to contain boron. Lacroix and de Gramont (1919) reported boron in Fiskenæsset kornerupine, while Herd (1973) found none. New analyses (ion microprobe mass analyser and spectrophotometric) of kornerupine in three specimens from the type locality, including the specimens analysed by Lorenzen and Herd, indicate the presence of boron in all three, in amounts ranging from 0.50 to 1.44 wt.% B203, e.g. (Li0.04 Na0.01 Ca0.01) (Mg3.49 Mn0.01 Fe0.17 Ti0.01 Al5.64)Σ9.30 (Si3.67 Al1.02 B0.31)Σ5 O21 (OH0.99 F0.01) for Lorenzen\u27s specimen. Textures and chemical compositions suggest that kornerupine crystallized in equilibrium in the following assemblages, all with anorthite (An 92-95) and phlogopite (XFe = atomic Fe/(Fe + Mg) = 0.028-0.035): (1) kornerupine (0.045)-gedrite (0.067); (2) kornerupine (0.038-0.050)-sapphirine (0.032-0.035); and (3) kornerupine (0.050)-hornblende. Fluorine contents of kornerupine range from 0.01 to 0.06%, of phlogopite, from 0.09 to 0.10%. In the first assemblage, sapphirine (0.040) and corundum are enclosed in radiating bundles of kornerupine; additionally sapphirine, corundum, and/or gedrite occur with chlorite and pinite (cordierite?) as breakdown products of kornerupine. Kornerupine may have formed by reactions such as: gedrite + sapphirine + corundum + B203 (in solution) + H20 = kornerupine + anorthite + Na-phlogopite under conditions of the granulite facies. Boron for kornerupine formation was most likely remobilized by hydrous fluids from metasedimentary rocks occurring along the upper contact of the Fiskenæsset gabbro-anorthosite complex with amphibolite

Adverse Childhood Experiences: Raising Awareness & Creating Easier Access to Resources

Adverse Childhood Experiences (ACEs) such as abuse, neglect, and witnessing household dysfunction are common throughout the United States and are occurring in our own communities. ACEs impose immediate health risks to children but also are associated with poor health outcomes in adulthood including higher rates of cancer, heart disease, chronic lung disease, obesity, depression and substance use. The goal of this project was to contribute to prevention strategies for ACEs. This was accomplished by using flyers to raise awareness and educate the community on the prevalence and outcomes of ACEs, and by using QR codes to make parenting resources easily accessible.https://scholarworks.uvm.edu/fmclerk/1701/thumbnail.jp
