Case report

A 44 year-old man with a history of recurrent deep vein thromboses and pulmonary embolism was admitted to the hospital with bilateral pulmonary emboli and an acute, non-occlusive DVT of the left common femoral vein. He had recently been hospitalized and diagnosed with Coombs-positive hemolytic anemia and was treated with prednisone. On physical examination, the patient was noted to have a eunuchoid body habitus, with complete absence of chest, axillary and abdominal hair. Gynecomastia was present and his testes were found to be 2cm and firm to palpation

Prediction of Mississippi-Valley type ore fluid metal concentrations from solid solution metal concentrations in ore-stage minerals

Mississippi-Valley-type (MVT) deposits have some of the greatest enrichments of Pb, Zn, Ba, and F in the Earth's crust. Fundamental to understanding how these elements were transported and precipitated to form MVT deposits is knowledge of their concentrations in the ore fluids. Recent research aimed at determining the concentrations of Pb, Zn, and Ba in the ore fluids that formed the MVT deposits of the U.S. midcontinent, the type examples for the MVT deposit class, has focused on using LA-ICPMS to analyze fluid inclusions. This research has shown U.S. mid-continent MVT ore fluids to have Ba concentrations on the order of 10's of ppm. However, LA-ICP-MS results for Pb and Zn concentrations are equivocal due to interferences from Zn and Pb in the host mineral matrix and uncertainties about whether the measured Pb and Zn signals represent aqueous solute or "accidentals", i.e. Pb or Zn solid particulates entrained within the fluid inclusions. In light of these limitations, this study sought to determine metal concentrations in MVT ore fluids instead by calculating them theoretically based on their solid solution concentrations in the ore-stage minerals calcite and galena. Using experimental partition coefficients from Rimstidt et al. (1998) at ore stage temperatures and measured compositions of ore-stage calcite from the Illinois-Kentucky and Central Tennessee MVT districts, concentrations of Mg, Mn, Fe, Zn, Sr, Ba, and Pb in the ore fluid were predicted. The predicted ore fluid concentrations of Mg and Mn, which form carbonate minerals (magnesite and rhodochrosite) with the calcite structure, were in good agreement with available fluid inclusion data for these elements. Thus, the predicted ore fluid concentrations of Zn and Fe, which also form carbonate minerals (smithsonite and siderite) with the calcite structure, 10s of ppm Zn and 1s to 10s of ppm Fe in Illinois-Kentucky and a maximum of 10s of ppm Zn and 1s to 10s of ppm Fe in Central Tennessee , are likely to be accurate. These Zn concentrations are typical of modern sedimentary brines and high enough to allow efficient Zn ore formation. In contrast, the predicted ore fluid concentrations of Sr and Ba, which form carbonate minerals (strontianite and witherite) with the aragonite structure, were in poor agreement with available fluid inclusion data for these elements. Thus, the predicted 1s of ppm ore fluid concentration of Pb, which also forms a carbonate mineral (cerussite) with the aragonite structure, is unlikely to be accurate. Using predicted thermodynamic data (Sverjensky, 1985) for ZnS with the galena structure, a thermodynamic distribution coefficient for Zn between aqueous solution and solid solution in galena was calculated. This distribution coefficient was used in combination with Zn concentrations measured in solid solution in galena from the Central Missouri, Central Tennessee, Illinois-Kentucky, Northern Arkansas, Tri-State, and Southeast Missouri MVT districts to predict Zn/Pb ratios for the ore fluids. The Zn/Pb ratios do not agree with the ore Zn/Pb ratios of the districts and appear to be an artifact of the temperature used in the calculations. Therefore the predicted ore fluid Zn/Pb ratios are unlikely to be correct

The effect of a morphological awareness intervention on early writing outcomes

Dissertation supervisor: Dr. Erica Lembke.Includes vita.The purpose of this study was to investigate the effect of a morphological awareness intervention on the spelling and sentence writing performance and growth of second (n = 17) and third (n = 10) grade students at risk for writing difficulty. The intervention was provided in 25 minute sessions four to five times per week for five weeks. Students were individually randomly assigned to either the intervention (n = 13) or the comparison (n = 14) condition. Students were pre- and post-tested using standardized tests of spelling and writing and a curriculum-based measure of sentence writing (CBM-W). Additionally, students were given a working memory index as a covariate and an oral language subtest as a counterfactual measure. All participants were also given the CBM-W task twice weekly as a progress monitoring measure. Intervention effects were measured using a series of t-tests and a multi-variate analysis of covariane (MANCOVA). Growth on the progress monitoring task was measured using hierarchical linear modeling (HLM). Results indicated that students in the intervention significantly improved their spelling as a result of the intervention, but this result was attenuated when controlling for working memory. Student-level characteristics that predicted growth were baseline spelling ability and grade level. Students who were younger and poorer spellers to begin with made the most growth on the CBM-W sentence writing task.Includes bibliographical references (pages 102-122)
