Creep-fatigue behavior of NiCoCrAlY coated PWA 1480 superalloy single crystals

Single crystal specimens of a Ni base superalloy, PWA 1480, with a low pressure plasma sprayed NiCoCrAlY coating were tested in various 0.1 Hz fatigue and creep fatigue cycles both at 1015 and 1050 C. Creep fatigue tests of the cp, pc, and cc types were conducted with various constant total strain ranges employing creep dwells at various constant stresses. Considerable cyclic softening occurred as was evidenced particularly by rapidly increasing creep rates in the creep fatigue tests. The cycle time in the creep fatigue tests typically decreased by more than 80 percent at 0.5 N sub f. Though cyclic life did correlate with delta epsilon sub in a better correlation existed with sub f for both the fatigue and creep fatigue tests, and poor correlations were observed with either sigma sub max or the average cycle time. A model containing both delta sigma and delta sigma (sub in), N sub f = alpha delta sigma (sub in) beta delta sigma gamma, with best fit values of sigma for each cycle type, but the same values of beta and gamam, was found to provide good correlations. Life lines were not greatly different among the cycle types, differing only by a factor of about three. The cp cycle life line was lowest for both test temperatures, however among the other three cycle types there was no consistent ranking. For all test types failure occurred predominately by multiple internal cracking originating at pores. The strong correlation of life with delta sigma may reflect a significant crack growth period in the life of the specimens

Which one is better: presentation-based or content-based math search?

Mathematical content is a valuable information source and retrieving this content has become an important issue. This paper compares two searching strategies for math expressions: presentation-based and content-based approaches. Presentation-based search uses state-of-the-art math search system while content-based search uses semantic enrichment of math expressions to convert math expressions into their content forms and searching is done using these content-based expressions. By considering the meaning of math expressions, the quality of search system is improved over presentation-based systems

Urban wind power and the private sector : community benefits, social acceptance and public engagement

Given the ambitious government targets for renewable energy generation in the UK, there has been a push by government and industry towards various types and scales of Renewable Energy Technologies (RETs). This paper explores the implications of commercial urban wind projects for local communities, drawing on a case study of proposals by ASDA to construct wind turbines in two semi-urban locations in the UK. The paper argues that community responses to the proposals were complex and varied and could not adequately be encapsulated by 'nimby' (not in my back yard) assignations. It concludes that while ASDA followed a process of consulting local people, this process highlighted the problems of the 'business as usual' approach to public engagement employed by ASDA, and assumptions made about public acceptance of RETs

An investigation of environmental influence on the creep behavior of a low pressure plasma sprayed NiCoCrAlY alloy

Low pressure sprayed MCrAlY overlay coatings are currently being used on advanced single crystal superalloy blades for gas turbine engines. Many studies were made on the influence of coatings on the mechanical properties of superalloys in oxidizing or hot-corroding environments, but very few on the properties of the bulk coating alloy itself. The creep behavior of a typical NiCoCrAlY alloyd (PWA 276) was studied in air and vacuum. The as-received low pressure plasma sprayed NiCoCrAlY plates were heat treated for 4 h at 1080 C followed by 32 h at 870 C, the heat treatment applied to coated superalloy parts. Standard creep specimens 12.7 mm long and 3.2 mm in diameter were then machined. Constant load creep-rupture tests were performed in air and vacuum at 650, 850, and 1050 C and various initial stresses. In addition, some specimens were preoxidized at 1050 C for 100 h prior to testing. Results are briefly discussed

VMEXT: A Visualization Tool for Mathematical Expression Trees

Mathematical expressions can be represented as a tree consisting of terminal symbols, such as identifiers or numbers (leaf nodes), and functions or operators (non-leaf nodes). Expression trees are an important mechanism for storing and processing mathematical expressions as well as the most frequently used visualization of the structure of mathematical expressions. Typically, researchers and practitioners manually visualize expression trees using general-purpose tools. This approach is laborious, redundant, and error-prone. Manual visualizations represent a user's notion of what the markup of an expression should be, but not necessarily what the actual markup is. This paper presents VMEXT - a free and open source tool to directly visualize expression trees from parallel MathML. VMEXT simultaneously visualizes the presentation elements and the semantic structure of mathematical expressions to enable users to quickly spot deficiencies in the Content MathML markup that does not affect the presentation of the expression. Identifying such discrepancies previously required reading the verbose and complex MathML markup. VMEXT also allows one to visualize similar and identical elements of two expressions. Visualizing expression similarity can support support developers in designing retrieval approaches and enable improved interaction concepts for users of mathematical information retrieval systems. We demonstrate VMEXT's visualizations in two web-based applications. The first application presents the visualizations alone. The second application shows a possible integration of the visualizations in systems for mathematical knowledge management and mathematical information retrieval. The application converts LaTeX input to parallel MathML, computes basic similarity measures for mathematical expressions, and visualizes the results using VMEXT.Comment: 15 pages, 4 figures, Intelligent Computer Mathematics - 10th International Conference CICM 2017, Edinburgh, UK, July 17-21, 2017, Proceeding

TBK1 and IKKε act redundantly to mediate STING-induced NF-κB responses in myeloid cells

Stimulator of Interferon Genes (STING) is a critical component of host innate immune defense but can contribute to chronic autoimmune or autoinflammatory disease. Once activated, the cyclic guanosine monophosphate (GMP)-adenosine monophosphate (AMP) (cGAMP) synthase (cGAS)-STING pathway induces both type I interferon (IFN) expression and nuclear factor-κB (NF-κB)-mediated cytokine production. Currently, these two signaling arms are thought to be mediated by a single upstream kinase, TANK-binding kinase 1 (TBK1). Here, using genetic and pharmacological approaches, we show that TBK1 alone is dispensable for STING-induced NF-κB responses in human and mouse immune cells, as well as in vivo. We further demonstrate that TBK1 acts redundantly with IκB kinase ε (IKKε) to drive NF-κB upon STING activation. Interestingly, we show that activation of IFN regulatory factor 3 (IRF3) is highly dependent on TBK1 kinase activity, whereas NF-κB is significantly less sensitive to TBK1/IKKε kinase inhibition. Our work redefines signaling events downstream of cGAS-STING. Our findings further suggest that cGAS-STING will need to be targeted directly to effectively ameliorate the inflammation underpinning disorders associated with STING hyperactivity

Meeting the Public Health Workforce’s Training Priorities in Georgia and the Southeast

Background: The mission of the Region IV Public Health Training Center (R-IV PHTC) is to build knowledge and skills in the public health workforce in the eight states of HHS Region IV by providing competency-based training. Workforce training needs are changing quickly and dramatically in light of new developments in public health practice and science, emerging diseases, changes in the health care environment, and the growing emphasis on inter-professional practice. Additionally, a 2014 survey conducted by the Association of State and Territorial Health Officials (ASTHO) found that at least 38% of the current public health workforce plans to retire by 2020. Therefore, it is increasingly crucial to prepare upcoming managers for leadership positions and to train entry-level workers to assume more advanced roles. Methods: To address current and emerging training needs in Georgia and the southeast, the R-IV PHTC continually identifies emerging priorities and effective training approaches. It explores training needs through a review of formal needs assessments, key stakeholder interviews, surveys of targeted audiences, informal partner communications, and training evaluation data. An interactive component of the GPHA session allowed participants to identify and discuss their own professional training needs. Results: Workforce development needs assessments data across several southeastern states identified recurring training needs for professionals in Tiers 1, 2 and 3 of the Council on Linkages Core Competency domains for Analytical/Assessment Skills and Financial Planning/Management. In Georgia, top competency training needs gathered from a variety of assessment methods included Cultural Competency, Communication, Financial Planning/Management, Public Health Science, and Leadership/Systems Thinking. Participants in the workshop’s interactive component expressed highest personal need for training in Financial Planning/Management, Analytical/Assessment Skills, and Policy Development/Program Planning. However, for others in their organizations, they identified a priority need for leadership training. Conclusions: The R-IV PHTC assesses training needs and provides training resources to respond to current and emerging public health workforce development needs in Georgia and the southeast

A Region-Wide Field Placement Program Built on the Foundation of Mentorship and Professionalism

Background: The Region IV Public Health Training Center (R-IV PHTC) provides public health students from the eight states of HHS Region IV with essential practice experiences that demonstrate the value of working with underserved populations. The Pathways to Practice Scholars field placement program is built on a foundation of mentorship, professionalism, and community. Methods: Sixteen student scholars (13 graduate; 3 undergraduate) were selected to work during May-August 2015 in practiceoriented agencies serving underserved populations. Each scholar received a $1500 living allowance. Seven of 16 accepted an internship outside the state of their university. In conjunction with mentors, Scholars developed work plans based on Council on Linkages Core Competency domains. Requirements included a pre-, mid- and post-assessment, an executive summary/reflection, and a virtual webinar presentation. Results: Student Scholars worked at sites across eight states in state or local health departments, Area Health Education Centers (AHECs), and healthcare settings. Students identified Core Competency domains they developed most during the field placement: Communication, Analytical/Assessment, Leadership/Systems Thinking, and Community Engagement. The R-IV PHTC asked mentors to treat interns as valued employees and include them in activities beyond their specific project. Indicators of successful mentorship included expressed appreciation for student assistance and the desire to enrich the student experience while benefiting the agency mission. Mentors provided clearly defined projects for a short timeframe (10-12 weeks), adjusted to the students’ capacity and readiness, and offered opportunities to apply classroom skills to practice. They helped students develop immediately useful products in collaboration with community stakeholders. Conclusions: Mentors play a crucial role in the development and success of field placement students, but students and mentors share equal responsibility in fostering the relationship. Past case studies from this program demonstrate that some students find employment in these same agencies after graduation, and become mentors for future students, thus, creating a self-perpetuating learning community

Enhancing the Future Public Health Workforce Through Competency-Based Student Field Placements

Background: The Public Health Workforce Interest and Needs (PHWINS) 2014 survey from ASTHO (Association of State and Territorial Health Officials) demonstrated a dramatic need for succession planning and retention of the future public health workforce. To address this need, the Region IV Public Health Training Center’s (R-IV PHTC) Pathways to Practice Scholars Program places students from accredited schools and programs of public health into practical field placement positions across eight states. Skill- and competency-based student field placements reinforce the value of working with medically underserved areas/populations (MUA/Ps) through public health agencies. Field placements use adult learning theory through experiential learning to build essential skills from the Council on Linkage (COL) core competencies. Methods: Host agencies include state and local health departments, Area Health Education Centers, primary care settings, and community organizations in one of eight southeastern states serving MUA/Ps. Agencies propose practical projects using COL domains. Proposals are converted to job postings. Once an agency selects a student, the team collaboratively develops a detailed work plan using specific COL competencies. Results: A brief overview of evaluation findings will be shared but are not the focus of this workshop. Evaluation instruments included a pre-survey, work plan, mid-term survey, final evaluation, and alumni survey. Students submit a final report, reflection summary, webinar presentation and/or abstract worthy of submission to a professional conference. Findings demonstrated increases in students’ perceived ability to perform core competencies and future plans to work in MUA/Ps. Conclusions: This program builds leadership and real-world experience in the future workforce while serving immediate needs of public health agencies. The workshop focuses on interactive discussion about processes and tools to create COL competencybased field placement position descriptions and detailed work plans. Participants can engage in dialogue about developing student positions which enhance their work while training the future workforce
