    Automation concepts and gripping solutions for bonding with reactive multilayer systems

    Reactive multilayer systems (RMS) represent an innovative heat source for the establishment of solder joints. They offer fast bonding processes that introduce very little thermal input and internal stress on the bonded parts. The current application process of RMS is predominantly manual labor. There are a couple of challenges to be overcome to automate this process, a requirement for its introduction into industrial production. In this paper we evaluate the requirements for an automated joining process with RMS and devise a concept of a modular assembly system for different product structures. Furthermore we show our results in gently and reliably gripping and handling of RMS.Federal Ministry of Economic and Technology (BMWi)InnoJoin GmbH & Co. KG, Breme

    Agronomic and Animal Performance of Different Tall Fescue Varieties

    The objective of the tall fescue breeding program is the development of varieties characterized by superior nutritive value (including reduced contents of perloline and loline alkaloids and minimal infestation of the fungal endophyte, Acremonium coenophialum), palatability, disease resistance, and adaptation through the utilization of intergeneric and interspecific hybrid derivatives of ryegrass and tall fescue species. Kentucky 31, Kenwell, and Kenhy were previously released from this breeding program. Johnstone tall fescue, developed cooperatively by the Kentucky Agricultural Experiment Station and USDA-ARS, was released March 1, 1982 as a new variety. Johnstone is characterized as having low levels of perloline alkaloid and the fungal endophyte (Acremonium coenophialum) and improved forage quality during summer. It is expected that seed of Johnstone will be available commercially during 1985, and a good supply be available for /\u27 spring and summer 1986 plantings

    The objective of the tall fescue breeding program at the University of Kentucky is the development of varieties characterized by superior nutritive value (including reduced levels of perloline and loline alkaloids), minimal infestation of the fungal endophyte, Acremonium coenophialum), higher palatability, improved disease resistance, and wider adaptation through the derivation of intergeneric and interspecific hybrids of ryegrass and tall fescue species. Kentucky 31, Kenwell, and Kenhy were varieties released from this breeding program. Johnstone tall fescue, developed cooperatively by the Kentucky Agricultural Experiment Station and USDA-ARS, is the most recently released variety. It is characterized as having low levels of perloline alkaloid and the fungal endophyte (Acremonium coenophialum) and improved forage quality during summer. Ample Johnstone seed should be available to meet demand during 1986

    Review of use of the Trials within Cohorts (TwiCs) design approach

    No full text
    Introduction: Trials within Cohorts (TwiCs) is an innovative approach to the design and conduct of multiple randomised controlled trials (RCTs) (Relton et al, 2010). This approach utilises an observational cohort to recruit trial populations and obtain short and longer term outcomes. We describe what is currently known about the use of this design approach. Methods: An extension of the 2010 Consolidated Standards of Reporting Trials (CONSORT) Statements for RCTs using cohorts and/or routinely collected health data is in development, supported by a scoping review that includes publications of methods or reports ofprotocols or results from RCTs using cohorts, registries, electronic health records and administrative databases. Data sources for this scoping review included Medline and Cochrane Methodology Register and were limited to English language. This review of use of the TwiCs approach uses publications of methods or reports of protocols or results from RCTs that use cohorts to recruit identified in the scoping review. This is supplemented with information from topic experts. We report: (i) types of cohorts (setting, population, condition/ disease area), (ii) how the cohorts are utilised (identifying potential trial participants, recruitment, randomisation, process and outcome data collection including bespoke and/or routine health record data, types of trials conducted/ planned), (iii) approaches to informed consent, e.g. staged approach (Young-Afat et al, 2016), and (iv) any purported and/or real study design (in)efficiencies. Timing of Potential Results: Early results indicate 75+ eligible full text articles, including 23 trial protocols and 23 articles reporting the results of trials using cohorts. Full results will be available in August 2019 and presented at the conference. Potential Relevance and Impact: Standard approaches to trial design are often costly and frequently fail to recruit sufficiently large or representative samples. This review will help provide information on the use and potential (in)efficiency of the TwiCs approac
