Abstract The subject of the research was a catastrophic recorder of the S2-3a system for recording flight parameters, developed at the Air Force Institute of Technology. The article discusses tests of catastrophic recorders’ resilience to factors present at aircraft accidents. The document specifying the requirements for catastrophic recorders of flight parameters includes the defence standard: NO-16-A200, and the European standard: EuroCAE ED-112. According to NO-16-A200 and ED-112 standards, the protective unit should be resistant to: g-forces existing during crash, puncture, compression, fire, underwater pressure and aggressive liquids.

Abstract Introduction We evaluated the effectiveness of New Orientation for Reducing Threats to Health from Secretive-problems That Affect Readiness (NORTH STAR), a community assessment, planning, and action framework to reduce the prevalence of suicidality, substance problems, intimate partner violence, and child abuse. Materials and Methods One-third of U.S. Air Force bases worldwide were randomly assigned to NORTH STAR (n = 12) or an assessment-and-feedback-only condition (n = 12). Two Air Force-wide, cross-sectional, anonymous, web-based surveys were conducted of randomly selected samples assessing risk/protective factors and outcomes. This study was reviewed and approved by the institutional review board at the investigators’ university and by the institutional review board at Fort Detrick. Results NORTH STAR, relative to control, bases experienced a 33% absolute risk reduction in hazardous drinking rates and cumulative risk, although, given the small number of bases, these effects were not statistically significant. Conclusions Given its relatively low cost, use of empirically supported light-touch interventions, and emphasis on sustainability with existing resources, NORTH STAR may be a useful system for prevention of a range of adult behavioral health problems that are difficult to impact.

The Impact

Abstract An analysis of longitudinal impact tests that were made by Drs. D. S. Clark and P. E. Duwez at the California Institute of Technology on an iron and a steel with definite yield points is described. From this analysis is deduced the probable nature of the dynamic stress-strain relations for such materials. These appear to differ greatly from the static stress-strain relations, unlike the case for materials without yield points. As pointed out by Duwez and Clark, the upper yield stress for undeformed material is several times as great under impact as the static yield stress. The present analysis indicates that under impact, the material with a definite yield point is made harder at a given deformation, and ruptures at a higher (engineering) stress and smaller strain than when loaded statically. The critical impact velocity, defined as that at which nearly instantaneous failure occurs in tension, is discussed, and the factors upon which it depends are given.

The current Covid-19 pandemic has had many effects on human life globally, including the implementation of education. This study aimed to obtain the impact of the Covid-19 pandemic on learning outcomes in higher education. The research method used is a cross-sectional study. The data were taken from the test results at the end of the lecture, observations, and interviews. The research was conducted at the University of Muhammadiyah Lampung, IPDN Jatinangor Campus, and the Ahmad Dahlan Institute of Technology and Business, with 120 students participating. The data analysis technique used the percentage technique and cross-tabulation. The study results concluded that student learning outcomes decreased in the 2020-2021 academic year compared to the 2019-2020 academic year. The decline in learning outcomes includes knowledge, skills, and psychology. This finding has implications for the understanding of education personnel regarding online teaching and learning design during the Covid-19 pandemic.

The Impact

<p>The aim of this research was to describe how undergraduate midwifery students’ engagement with learning is impacted when they have teaching delivered by different methods of instruction. It asks the question: does flexible delivery of teaching impact on their ability to engage in their learning? This research describes the impact of different modes of flexible delivery of teaching within a new curriculum on students in a pre-registration midwifery undergraduate programme at Waikato Institute of Technology (Wintec), New Zealand. This new curriculum commenced in 2010 as a response to legislative and industry driven changes to midwifery education in New Zealand. The research used an on-line survey to ask students enrolled in years one and two of the programme and those who had exited the programme during the same timeframe, A range of questions about their learning experiences. Surveys were sent to 104 enrolled students and 15 students that had exited the BMid programme. Fifty two (50%) responses were received from the enrolled students and three (20%) from those that had exited the programme. There were three key findings of this research. Firstly the participants identified differences with their sense of belonging amongst their peers, tutors and the administration team outside of their regional learning hubs. The second key and unsurprising finding was that respondents across the board preferred face-to-face sessions to video conferencing sessions and thirdly that the demographic profile of the respondents from the regional learning hubs was different to those attending from the Hamilton city hub. The implications of these key findings are; · For tertiary institutions to acknowledge and consider the links between high quality learning, student engagement and outcomes. · To support the need for continuing training and education for both faculty and students with regards to flexible delivery of teaching and to provide professional development and relevant technology to support more interactive forms of learning if delivered via video conferencing or by online activities. · To further research the needs of Māori students and those who have exited the programme in order to discover what would need to change in order for them to continue with their studies.</p>

The study has been intended to present some selected service-imposed issues with the transmission system of the Mi-24 combat helicopter. An attempt has been made to present predictions about possible threats/hazards to the transmission system of this helicopter. The forecast has been based on the FAM-C analysis of changes in instantaneous frequency against time and, to some extent, on mechanical measurements of disassembled structural components/subassemblies. The greatest emphasis has been laid on capabilities to identify and diagnose locations in structural components of the Mi-24 helicopter (where many and various hazards may arise) using the non-destructive diagnostic method FAM-C developed at ITWL (Air Force Institute of Technology). The method has been based on the tracking of parameters of modulation of airborne alternator produced frequencies. The testing requires no extra sensors, since the built-in airborne AC, DC, and tachogenerators themselves are the diagnostic transducers. While taking FAM-C measurements, the transmission system experiences no extra loads or rotational-speed distortions.

Research studies that are conducted by both the Air Force Institute of Technology (AFIT) and other domestic and foreign organizations indicate that investigations of corrosion phenomena present a very important factor with respect to prolongation of technical resources and operation of aircraft driven by their actual technical condition. The investigation of the corrosion degree and deterioration of protective coatings must be carried out in a systemic manner with thorough analysis of information that bring together the aircraft operation and the processes of corrosion and deterioration of protective coatings. The investigation must comprise measurements of the atmospheric corrosion in order to determine corrosive aggressiveness of the atmosphere and establish frequency and scope of corrosion inspection. Only the analysis of gathered information with its characteristics may guarantee safe operation of structural components of aircrafts according to their actual technical condition. This paper outlines the approach to corrosion investigation that is in place in AFIT.
