Grinding as an approach to the production of high-strength, dispersion-strengthened nickel-base alloys

Mechanical process produces dispersion-strengthened metal alloys. Power surface contamination during milling is removed by a cleaning method that involves heating thin shapes or partially-compacted milled powder blends in hydrogen to carefully controlled temperature schedules

Method for alleviating thermal stress damage in laminates

A method is provided for alleviating the stress damage in metallic matrix composites, such as laminated sheet or foil composites. Discontinuities are positively introduced into the interface between the layers so as to reduce the thermal stress produced by unequal expansion of the materials making up the composite. Although a number of discrete elements could be used to form one of the layers and thus carry out this purpose, the discontinuities are preferably produced by simply drilling holes in the metallic matrix layer or by forming grooves in a grid pattern in this layer

The Exemption Laws of Washington

Remington\u27s Compiled Statutes for 1922, Section 563, specifies what property shall be exempt from execution and Section 703 specifies the amount of wages exempt from garnishment. This note will discuss these two exemption sections only and will not include the homestead law, which in a sense is itself an exemption law

Production and processing of Cu-Cr-Nb alloys

A new Cu-based alloy possessing high strength, high conductivity, and good stability at elevated temperatures was recently produced. This paper details the melting of the master alloys, production of rapidly solidified ribbon, and processing of the ribbon to sheet by hot pressing and hot rolling

Is high self-esteem beneficial? Revisiting a classic question

Debates about the benefits of self-esteem have persisted for decades, both in the scientific literature and in the popular press. Although many researchers and lay people have argued that high self-esteem helps individuals adapt to and succeed in a variety of life domains, there is widespread skepticism about this claim. The present article takes a new look at the voluminous body of research (including several meta-analyses) examining the consequences of self-esteem for several important life domains: relationships, school, work, mental health, physical health, and antisocial behavior. Overall, the findings suggest that self-esteem is beneficial in all these domains, and that these benefits hold across age, gender, and race/ethnicity, and controlling for prior levels of the predicted outcomes and potential third variable confounds. The meta-analytic estimates of self-esteem effects (which average .10 across domains) are comparable in size to estimates for other hypothesized causal factors such as self-efficacy, positive emotionality, attachment security, and growth mindset, and larger than some generally accepted pharmaceutical interventions. Discussion focuses on several issues that are critical for evaluating the findings, including the strength of the evidence for making causal inferences, the magnitude of the effects, the importance of distinguishing between self-esteem and narcissism, and the generalizability of the results. In summary, the present findings support theoretical conceptions of self-esteem as an adaptive trait that has wide-ranging influences on healthy adjustment and adaptation, and suggest that interventions aimed at boosting self-esteem might, if properly designed and implemented, benefit individuals and society as a whole.

The benefits of self-esteem: Reply to Krueger et al. (2022) and Brummelman (2022)

Krueger et al. (2022) argue that our review (Orth & Robins, 2022) finds benefits of self-esteem primarily for subjective outcomes and largely fails to demonstrate any "objective" benefits. We disagree with this portrayal of the findings and highlight research that provides evidence for the benefits of self-esteem using objective measures. We also address Krueger et al.'s claim that positivity bias in self-reports can account for the effects of self-esteem on subjectively assessed life outcomes, and explain how the statistical analyses used to document these effects substantially control for this bias. We maintain that there is now a large body of evidence from meta-analyses and large-scale longitudinal studies demonstrating that high self-esteem has adaptive consequences for social relationships, school, work, mental health, physical health, and antisocial behavior. Brummelman (2022) presents a compelling theoretical framework that can guide the design of interventions to improve children's self-esteem. We agree with his concerns about the need for randomized controlled trials to evaluate the efficacy of self-esteem interventions and the importance of ensuring that children's self-esteem can be raised without causing them to become narcissistic. The research reviewed in our article indicates that high self-esteem is adaptive for children, adolescents, and adults, suggesting that well-designed and effective self-esteem interventions might be beneficial for individuals of all ages.

Antechamber facilitates loading and unloading of vacuum furnace

Antechamber facilitates the use of a furnace in which materials are heat treated in a high vacuum or a gas atmosphere. It has a high vacuum pumping system, a means for backfilling with a selected gas, an access door, glove ports, and a motor driven platform

Interplanetary propulsion using inertial fusion

Inertial fusion can be used to power spacecraft within the solar system and beyond. Such spacecraft have the potential for short-duration manned-mission performance exceeding other technologies. We are conducting a study to assess the systems aspects of inertial fusion as applied to such missions, based on the conceptual engine design of Hyde (1983) we describe the required systems for an entirely new spacecraft design called VISTA that is based on the use of DT fuel. We give preliminary design details for the power conversion and power conditioning systems for manned missions to Mars of total duration of about 100 days. Specific mission performance results will be published elsewhere, after the study has been completed

Low self-esteem prospectively predicts depression in adolescence and young adulthood

Low self-esteem and depression are strongly correlated in cross-sectional studies, yet little is known about their prospective effects on each other. The vulnerability model hypothesizes that low self-esteem serves as a risk factor for depression, whereas the scar model hypothesizes that low self-esteem is an outcome, not a cause, of depression. To test these models, the authors used 2 large longitudinal data sets, each with 4 repeated assessments between the ages of 15 and 21 years and 18 and 21 years, respectively. Cross-lagged regression analyses indicated that low self-esteem predicted subsequent levels of depression, but depression did not predict subsequent levels of self-esteem. These findings held for both men and women and after controlling for content overlap between the self-esteem and depression scales. Thus, the results supported the vulnerability model, but not the scar model, of self-esteem and depression

The Seagrasses of the Mid-Atlantic Coast of the United States

The mid-Atlantic region of the United States includes four states: Delaware, Maryland, Virginia and North Carolina. It is characterized by numerous estuaries and barrier- island coastal lagoons with expansive salt marshes and seagrass beds in most shallow-water areas. There are no rocky shores . Hard substrates are either man-made [rock jetties and riprap or wood pilings) or biogeniclly generated [oyster and worm reefs). Sediments are predominantly quartz sand in shallow exposed areas with finer grain sediments in deeper or well-protected areas . Marsh peat outcroppings or cohesive sediments are sometimes found in the subtidal areas adjacent to eroding marshes. Climatic variations are large with air temperatures ranging from - 10°C to 40°C and water temperatures ranging from 0°C to 30°C. Tides are equal and semi-diurnal but relatively small in range (maximum of 1.3 m during spring tides).https://scholarworks.wm.edu/vimsbooks/1159/thumbnail.jp
