Expressions to determine temperatures and emission measures for solar X-ray events from GOES measurements

Expressions which give the effective color temperatures and corresponding emission measures for solar X-ray events observed with instruments onboard any of the GOES satellites are developed. Theoretical spectra were used to simulate the solar X-ray input at a variety of plasma temperatures. These spectra were folded through the wavelength dependent transfer functions for the two GOES detectors. The resulting detector responses and their ratio as a function of plasma temperature were then fit with simple analytic curves. Over the entire range between 5 and 30 million degrees, these fits reproduce the calculated color temperatures within 2% and the calculated emission measures within 5%. With the theoretical spectra, similar expressions for any pair of broadband X-ray detectors whose sensitivities are limited to wavelengths between 0.2 and 100 A are calculable

Take my hand, help me out: Mental health recipients\u27 experience of the therapeutic relationship

The purpose of this study was to describe mental health service recipients\u27 experience of the therapeutic relationship. The research question was ‘what is therapeutic about the therapeutic relationship?’ This study was a secondary analysis of qualitative interviews conducted with persons with mental illness as part of a study of the experience of being understood. This secondary analysis used data from 20 interviews with community-dwelling adults with mental illness, who were asked to talk about the experience of being understood by a health-care provider. Data were analysed using an existential phenomenological approach. Individuals experienced therapeutic relationships against a backdrop of challenges, including mental illness, domestic violence, substance abuse, and homelessness. They had therapeutic relationships with nurses (psychiatric/mental health nurses and dialysis nurses), physicians (psychiatrists and general practitioners), psychologists, social workers, and counsellors. Experiences of the therapeutic relationship were expressed in three figural themes, titled using participants\u27 own words: ‘relate to me’, ‘know me as a person’, and ‘get to the solution’. The ways in which these participants described therapeutic relationships challenge some long-held beliefs, such as the use of touch, self-disclosure, and blunt feedback. A therapeutic relationship for persons with mental illness requires in-depth personal knowledge, which is acquired only with time, understanding, and skill. Knowing the whole person, rather than knowing the person only as a service recipient, is key for practising nurses and nurse educators interested in enhancing the therapeutic potential of relationships

Loom to Legislature: Modeling the Effect of Textile and Garment Industry Employment on Women’s Political Power Through Comparative Analysis of Thailand and Viet Nam

Across the world, the textile and garment manufacturing industry provides first-employment opportunities to millions of women, particularly in developing countries. These jobs allow women to work outside of the home or family farm for the first time, exposing them to countless new opportunities that past generations lacked. Of these new opportunities, perhaps the most important are the political opportunities that arise from the greater economic and decision-making power afforded to women employed in the textile and garment industry. However, past literature is not conclusive as to the exact method by which employment leads to this increased political power for women in developing nations. Therefore, this paper presents 5 distinct hypotheses as to the conditions which allow for manufacturing employment, specifically in the textile and apparel sector, to increase the opportunity for women to become involved in politics and make independent political decisions. These hypotheses are then combined into a model to visualize the effects this employment has. This model is then tested through a comparative analysis of Thailand and Viet Nam, with each hypothesis being examined through the lens of the two Southeast Asian countries. This analysis serves as evidence for the model, with the differences between the two countries aligning with the theorized conditions necessary for apparel industry employment to have a positive effect on women&rsquo;s political power. As such, this model serves as a beginning point for further research into this relationship, having provided a plausible theoretical framework for how textile and garment manufacturing jobs can lead to greater political opportunities for women in developing nations.</p

The Effects of Processing Parameters on Defect Regularity in Ti-6Al-4V Parts Fabricated By Selective Laser Melting and Electron Beam Melting

Processing parameter has an important effect on Selective Laser Melting (SLM) and Electron Beam Melting (EBM) processes. Defects are easily formed by deviating from optimized processing parameters. This study purposely fabricated Ti-6Al-4V specimens with defects by varying process parameters from the factory default settings in both SLM and EBM equipment. Specimen’s density was measured based on the Archimedes method for estimating porosity. Microscopy of specimen’s top surface were observed to compare melt pool and overlap. “Marginal Parameters” is identified to describe the processing parameters which are capable of fabricating specimens with certain porosity. As a result, a correlation between defect regularity and marginal parameters has been established. The effect of marginal parameters on the melt pool is discussed to explain defect formation.Mechanical Engineerin

Real-Time Detection of Optical Transients with RAPTOR

Fast variability of optical objects is an interesting though poorly explored subject in modern astronomy. Real-time data processing and identification of transient celestial events in the images is very important for such study as it allows rapid follow-up with more sensitive instruments. We discuss an approach which we have developed for the RAPTOR project, a pioneering closed-loop system combining real-time transient detection with rapid follow-up. RAPTOR's data processing pipeline is able to identify and localize an optical transient within seconds after the observation. The testing we performed so far have been confirming the effectiveness of our method for the optical transient detection. The software pipeline we have developed for RAPTOR can easily be applied to the data from other experiments.Comment: 10 pages, 7 figures, to appear in SPIE proceedings vol. 484

Energetics and dynamics of simple impulsive solar flares

Flare energetics and dynamics were studied using observations of simple impulsive spike bursts. A large, homogeneous set of events was selected to enable the most definite tests possible of competing flare models, in the absence of spatially resolved observations. The emission mechanisms and specific flare models that were considered in this investigation are described, and the derivations of the parameters that were tested are presented. Results of the correlation analysis between soft and hard X-ray energetics are also presented. The ion conduction front model and tests of that model with the well-observed spike bursts are described. Finally, conclusions drawn from this investigation and suggestions for future studies are discussed
