The Effects of Additives on the Physical Properties of Electroformed Nickel and on the Stretch of Photoelectroformed Nickel Components

The process of nickel electroforming is becoming increasingly important in the manufacture of MST products, as it has the potential to replicate complex geometries with extremely high fidelity. Electroforming of nickel uses multi-component electrolyte formulations in order to maximise desirable product properties. In addition to nickel sulphamate (the major electrolyte component), formulation additives can also comprise nickel chloride (to increase nickel anode dissolution), sulphamic acid (to control pH), boric acid (to act as a pH buffer), hardening/levelling agents (to increase deposit hardness and lustre) and wetting agents (to aid surface wetting and thus prevent gas bubbles and void formation). This paper investigates the effects of some of these variables on internal stress and stretch as a function of applied current density.Comment: Submitted on behalf of TIMA Editions (http://irevues.inist.fr/tima-editions

Nurses - Tab Down Your Stress Level: A Pilot Study on the Use of Aromatherapy to Decrease Stress Levels

Introduction: The average day-to-day nursing profession is a stressful one. The job often requires dealing with patients enduring some of the worst times of their lives, as well as contending with patients\u27 emotional family members. This stressful environment is heightened even more for nurses employed in critical access hospitals (CAHs) due to the limited resources usually associated with these smaller facilities. Methods: Research and Evidence-Based Practice Council members at one CAH explored how to help nurses deal with the elevated work stress level. Aromatherapy tabs were used as an intervention to reduce nurses\u27 stress. The nurses who participated in this pilot study took a short survey before starting their shifts, indicating their stress levels. Following the survey, scented aromatherapy tabs were attached to the nurses\u27 uniforms and worn for the entirety of their shifts. At the end of their shifts, the participating nurses completed the same stress survey. Results: Twenty-five nurses participated in the pilot study. Nurses who did not wear the aromatherapy tab reported higher stress levels at the end of the shift than at the start, with a 3% overall average increase. Nurses who wore the aromatherapy tab reported lower stress levels at the end of the shift with a 12% overall average decrease. Discussion: Using aromatherapy tabs positively impacted nurses\u27 reported stress levels, indicating that aromatherapy tabs can be a tool for nurses to utilize within the workplace, supporting the need for further research

An informed approach to the development of primary care pediatric firearm safety messages

BACKGROUND: Firearm ownership is prevalent in the US and many children spend time in areas where firearms are not stored safely. The AAP recommends firearm safety counseling at pediatric well-visits. METHODS: We developed and tested six contextual messages to promote safe firearm storage based on: absence of harm, collective appeal to understanding child behavior, pediatrician\u27s authority, evidence-based, fear appeal, and general safety considerations. One hundred four parents who keep firearms at home were recruited from Amazon Mechanical Turk Prime and viewed video messages and reported behavioral intentions and emotional reactions following each message. RESULTS: All six contextual messages were perceived as important and believable and increased parents\u27 intentions to follow safety advice provided, but also elicited negative emotions. The authority message elicited more negative emotions and resulted in lower intentions to follow safe storage advice. CONCLUSIONS: Including firearm messages with other child safety advice merits further evaluation. Authority messages should be avoided

Excitations in the Halo Nucleus He-6 Following The Li-7(gamma,p)He-6 Reaction

A broad excited state was observed in 6-He with energy E_x = 5 +/- 1 MeV and width Gamma = 3 +/- 1 MeV, following the reaction Li-7(gamma,p)He-6. The state is consistent with a number of broad resonances predicted by recent cluster model calculations. The well-established reaction mechanism, combined with a simple and transparent analysis procedure confers considerable validity to this observation.Comment: 3 pages of LaTeX, 3 figures in PostScript, approved for publication in Phys.

A framework linking ecosystem services and human well‐being: Saltmarsh as a case study

1. The ecosystem services approach is based on the interdependencies between nature and human well‐being. However, while the ecosystem services aspect of this approach is well‐developed, the human well‐being aspect remains unstructured and vaguely defined. 2. An integrated conceptual framework was developed by adapting and linking the UK National Ecosystem Assessment‐Follow On framework with human well‐being domains. 3. As well as benefits, the notion of disbenefits was incorporated to recognise the potentially detrimental effects from interacting with nature. Benefits and disbenefits occur at the social–ecological interface and are classified by the seven domains of human well‐being they affect. 4. The framework is applied to saltmarsh habitat as a case study, highlighting knowledge gaps and the potential applicability and usefulness of the framework. In saltmarsh, benefits mainly accrue at larger scales with a greater impact affecting local to global individuals, while disbenefits tend to occur at a smaller scale and impact in‐situ individuals. 5. The framework provides in‐depth insight into links, trade‐offs and dichotomies between benefits and disbenefits and human well‐being, and improves accessibility to the complex research area of human well‐being. 6. This research can be a useful tool to guide environmental and health policy and management, as well as stakeholder engagement

Corra: Computational framework and tools for LC-MS discovery and targeted mass spectrometry-based proteomics

BACKGROUND: Quantitative proteomics holds great promise for identifying proteins that are differentially abundant between populations representing different physiological or disease states. A range of computational tools is now available for both isotopically labeled and label-free liquid chromatography mass spectrometry (LC-MS) based quantitative proteomics. However, they are generally not comparable to each other in terms of functionality, user interfaces, information input/output, and do not readily facilitate appropriate statistical data analysis. These limitations, along with the array of choices, present a daunting prospect for biologists, and other researchers not trained in bioinformatics, who wish to use LC-MS-based quantitative proteomics. RESULTS: We have developed Corra, a computational framework and tools for discovery-based LC-MS proteomics. Corra extends and adapts existing algorithms used for LC-MS-based proteomics, and statistical algorithms, originally developed for microarray data analyses, appropriate for LC-MS data analysis. Corra also adapts software engineering technologies (e.g. Google Web Toolkit, distributed processing) so that computationally intense data processing and statistical analyses can run on a remote server, while the user controls and manages the process from their own computer via a simple web interface. Corra also allows the user to output significantly differentially abundant LC-MS-detected peptide features in a form compatible with subsequent sequence identification via tandem mass spectrometry (MS/MS). We present two case studies to illustrate the application of Corra to commonly performed LC-MS-based biological workflows: a pilot biomarker discovery study of glycoproteins isolated from human plasma samples relevant to type 2 diabetes, and a study in yeast to identify in vivo targets of the protein kinase Ark1 via phosphopeptide profiling. CONCLUSION: The Corra computational framework leverages computational innovation to enable biologists or other researchers to process, analyze and visualize LC-MS data with what would otherwise be a complex and not user-friendly suite of tools. Corra enables appropriate statistical analyses, with controlled false-discovery rates, ultimately to inform subsequent targeted identification of differentially abundant peptides by MS/MS. For the user not trained in bioinformatics, Corra represents a complete, customizable, free and open source computational platform enabling LC-MS-based proteomic workflows, and as such, addresses an unmet need in the LC-MS proteomics field
