Preliminary design polymeric materials experiment

A typical Advanced Technology Laboratory mission flight plan was developed and used as a guideline for the identification of a number of experiment considerations. The experiment logistics beginning with sample preparation and ending with sample analysis are then overlaid on the mission in order to have a complete picture of the design requirements. The results of this preliminary design study fall into two categories. First specific preliminary designs of experiment hardware which is adaptable to a variety of mission requirements. Second, identification of those mission considerations which affect hardware design and will require further definition prior to final design. Finally, a program plan is presented which will provide the necessary experiment hardware in a realistic time period to match the planned shuttle flights. A bibliography of all material reviewed and consulted but not specifically referenced is provided

Judge\u27s Role in Settlement: Opinions from Missouri Judges and Attorneys, The

This study investigates judges\u27 involvement in settlement, and the opinions that Missouri judges and attorneys hold toward that involvement. In a survey of 1,100 judges and 1,550 attorneys, we found that Missouri judges differ significantly from Missouri attorneys. Specifically, Missouri judges prefer less judicial involvement in settlement and they, in the cases sent to them, were less aggressive in facilitating settlement. Finally, judges and attorneys from Missouri\u27s metropolitan areas were found to favor stronger involvement in settlement than were their counterparts from the non-metropolitan areas

Judicial Participation in Settlement

In the following pages, we will briefly delineate the settlement process, enumerate the techniques currently utilized by judges to facilitate settlement, and discuss the perceived ethics of these techniques. Finally, we will consider the circumstances under which judges typically participate in settlement

Reconstruction of the time-dependent electronic wave packet arising from molecular autoionization

Autoionizing resonances are paradigmatic examples of two-path wave interferences between direct photoionization, which takes a few attoseconds, and ionization via quasi-bound states, which takes much longer. Time-resolving the evolution of these interferences has been a long-standing goal, achieved recently in the helium atom owing to progress in attosecond technologies. However, already for the hydrogen molecule, similar time imaging has remained beyond reach due to the complex interplay between fast nuclear and electronic motions. We show how vibrationally resolved photoelectron spectra of H2 allow one to reconstruct the associated subfemtosecond autoionization dynamics by using the ultrafast nuclear dynamics as an internal clock, thus forgoing ultrashort pulses. Our procedure should be general for autoionization dynamics in molecules containing light nuclei, which are ubiquitous in chemistry and biologyThis work was supported by European Research Council advanced grant 290853-XCHEM within the seventh framework program of the European Union.

The Career Project: An Intervention to Facilitate Career Development

Students face substantial challenges in readying for their professional lives. They must select a field, find a suitable job within that field, and lay a foundation for their career. To aid with this, we present the career project, an efficient career- and self-exploration assignment. The project comprises a resume assessment, identifying short-term and long-term career goals, backup plans, personal strengths and selling points, conducting organizational research, an informational interview with someone in their desired field, and a market assessment by a knowledgeable professional. We tested the project efficacy with 803 students (two treatment groups and two controls) during an ‘Introduction to Management’ undergraduate course, using a between- and within-subject quasi-experimental design. The results strongly demonstrate the effectiveness of the project for accomplishing those goals. We note that the project can increase placement rate and salaries at graduation, which are major components of business school rankings and AACSB accreditation

Immunolocalization of RANKL is Increased and OPG Decreased During Dietary Magnesium Deficiency in the Rat

BACKGROUND: Epidemiological studies have linked low dietary magnesium (Mg) to low bone mineral density and osteoporosis. Mg deficiency in animal models has demonstrated a reduction in bone mass and increase in skeletal fragility. One major mechanism appears to be an increase in osteoclast number and bone resorption. The final pathway of osteoclastogenesis involves three constituents of a cytokine system: receptor activator of nuclear factor kB ligand (RANKL); its receptor, receptor activator of nuclear factor kB (RANK); and its soluble decoy receptor, osteoprotegerin (OPG). The relative presence of RANKL and OPG dictates osteoclastogenesis. The objective of this study was to assess the presence of RANKL and OPG in rats on a low Mg diet. METHODS: RANKL and OPG were assessed by immunocytochemistry staining in the tibia for up to 6 months in control rats on regular Mg intake (0.5 g/kg) and experimental rats on reduction of dietary Mg (.04%, 25% and 50% of this Nutrient Requirement). RESULTS: At all dietary Mg intakes, alteration in the presence of immunocytochemical staining of RANKL and OPG was observed. In general, OPG was decreased and RANKL increased, reflecting an alteration in the RANKL/OPG ratio toward increased osteoclastogenesis. CONCLUSION: We have, for the first time demonstrated that a reduction in dietary Mg in the rat alters the presence of RANKL and OPG and may explain the increase in osteoclast number and decrease in bone mass in this animal model. As some of these dietary intake reductions in terms of the RDA are present in a large segment of or population, Mg deficiency may be another risk factor for osteoporosis

Magnesium deficiency: effect on bone mineral density in the mouse appendicular skeleton

BACKGROUND: Dietary magnesium (Mg) deficiency in the mouse perturbs bone and mineral homeostasis. The objective of the present study was to evaluate bone mineral density of the femur in control and Mg-deficient mice. METHODS: BALB/c mice aged 28 days at study initiation were maintained on a normal or Mg deficient (0.0002% Mg) diet, and at time points 0, 2, 4 or 6 weeks bones were harvested for bone mineral density analysis. Peripheral quantitative computed tomography (pQCT) was used to assess the trabecular metaphyseal compartment and the cortical midshaft. RESULTS: Although mean total bone density of the femoral midshaft in Mg deficient mice did not differ significantly from controls throughout the study, the trabecular bone compartment showed significantly decreased mineral content after 4 (p < 0.001) and 6 weeks (p < 0.001) of Mg depletion. CONCLUSIONS: This study demonstrates the profound effect of Mg depletion on the trabecular compartment of bone, which, with its greater surface area and turnover, was more responsive to Mg depletion than cortical bone in the appendicular skeleton of the mouse
