    Applications of satellite data relay to problems of field seismology

    Get PDF
    A seismic signal processor was developed and tested for use with the NOAA-GOES satellite data collection system. Performance tests on recorded, as well as real time, short period signals indicate that the event recognition technique used is nearly perfect in its rejection of cultural signals and that data can be acquired in many swarm situations with the use of solid state buffer memories. Detailed circuit diagrams are provided. The design of a complete field data collection platform is discussed and the employment of data collection platforms in seismic network is reviewed

    Ethics of optometry: Student\u27s perspective of ethical dilemmas in our profession

    Get PDF
    Introduction: Optometry has a strong history of a commitment to professional ethics. In recent years, as optometry has expanded its scope of practice and assumed a more prominent role in the health care of the nation, there has been an interest in bringing a new broader application of ethical principles to the attention of the profession and its practitioners. The current trend amongst health care professional schools is to include ethics into the curriculum. There is a need for optometry to become a part of this movement. It is the goal of this study to address the ethical attitudes of current students in optometry school, which may show a need for ethics to be included into the optometric curriculum. Method: Surveys consisting of twelve questions were administered to students at various schools and colleges of optometry. Questions asked addressed ethical situations and dilemmas that practitioners are faced within the optometric profession. The data collected were analyzed to determine any differences in responses between gender, between those with some or no previous ethical training, and between schools and colleges of optometry. Results: Analysis of the data showed that there were some significant differences in responses to ethical encounters by gender, but no significant differences between those with different levels of previous ethical training or between optometry schools. Males tend to respond with a more legal approach, while females responded more with a gut feeling response. Conclusion: The results of this survey showed that current students of the optometric profession do have similar attitudes to current ethical situations and dilemmas within the profession. Nonetheless, this survey does not allow us to draw conclusions on whether or not ethics in the optometric curriculum will have an impact on the decisions that future practitioners will face

    Ultra-Wideband Communication and Sensor Fusion Platform for the Purpose of Multi-Perspective Localization.

    Localization is a keystone for a robot to work within its environment and with other robots. There have been many methods used to solve this problem. This paper deals with the use of beacon-based localization to answer the research question: Can ultra-wideband technology be used to effectively localize a robot with sensor fusion? This paper has developed an innovative solution for creating a sensor fusion platform that uses ultra-wideband communication as a localization method to allow an environment to be perceived and inspected in three dimensions from multiple perspectives simultaneously. A series of contributions have been presented, supported by an in-depth literature review regarding topics in this field of knowledge. The proposed method was then designed, built, and tested successfully in two different environments exceeding its required tolerances. The result of the testing and the ideas formulated throughout the paper were discussed and future work outlined on how to build upon this work in potential academic papers and projects

    Diet, smoking and lung cancer: a case-control study of 1000 cases and 1500 controls in South-West England

    We have examined the relationship between diet and lung cancer in a case–control study of 982 cases of lung cancer and 1486 population controls in south-west England in which subjects were interviewed personally about their smoking habits and their consumption of foods and supplements rich in retinol or carotene. Analyses were performed for 15 dietary variables, including intake of pre-formed retinol and carotene. There were significant associations (P< 0.01) with lung cancer risk for 13 of the variables, eight of which remained after adjustment for smoking. When the 15 variables were considered simultaneously, independent significant associations remained for 5: pre-formed retinol (increased risk), and fish liver oil, vitamin pills, carrots and tomato sauce (decreased risk). It is unlikely that all five associations represent biological effects, or that they can all be explained by residual confounding by smoking, or by biases. We conclude that there is at least one as yet unidentified factor that is causally related to lung cancer risk and of considerable importance in terms of attributable risk in this population. © 2001 Cancer Research Campaign http://www.bjcancer.co

    A Pilot Study on Cannabidiol (CBD) and Eccentric Exercise: Impact on Inflammation, Performance, and Pain

    International Journal of Exercise Science 16(2): 109-117, 2023. Cannabidiol (CBD) is a non-psychoactive cannabinoid purported to reduce symptoms of discomfort. Individuals are now using CBD to treat symptoms of multiple sclerosis, seizures, and chronic pain. Animal models indicate that CBD may be effective at reducing inflammation post fatiguing exercise. However, little evidence is available to evaluate these findings in humans. Therefore, the purpose of this investigation was to evaluate the impact of two doses of CBD oil on inflammation (IL-6), performance, and pain after an eccentric loading protocol. Participants (n = 4) participated in three conditions (placebo, low dose, and high dose), in this randomized, counterbalanced design. Each condition took 72 hours to complete, with a 1-week washout period between conditions. At the beginning of each week, participants were subjected to a loading protocol of six sets of ten eccentric only repetitions in the single-arm bicep curl. Participants consumed capsules of either a placebo, low dose (2mg/kg) or high dose (10mg/kg) of CBD oil immediately following the session and continued every twelve hours for 48 hours. Venipunctures were taken before exercise and repeated at 24, 48, and 72 hours post exercise. Blood samples were centrifuged for 15 minutes in gel and lithium heparin vacutainers. Plasma was separated from cells and stored at -80° until analysis. Samples were analyzed using an immunometric assay for IL-6 (ELISA). Data were analyzed using a three (condition) by four (time) repeated measure ANOVA. There were no differences in inflammation between conditions (F(2,6) = 0.726, p = 0.522, np2 = 0.195) or across time (F(3,9) = 0.752, p = 0.548, np2 = 0.200), handgrip strength between conditions (F(2,6) = 0.542, p = 0.607, np2 = .153) or across time (F(3,9) = 2.235, p = .153, np2 = .427), or bicep curl strength between conditions (F(2,6) = 0.675, p = 0.554, np2 = .184) or across time (F(3,9) = 3.513, p = .150, np2 = .539). There were no differences in pain between conditions (F(2,6) = 0.495, p = 0.633, np2 = .142), but there was a difference across time (F(3,9) = 7.028, p = .010, np2 = .701). There were no significant interactions to note. Although there was no statistical significance between conditions (likely due to the low sample size), there was a visible increase in IL-6 48 (4.88 ± 6.53) and 72 hours (3.12 ± 4.26) post exercise in the placebo condition which was not observed in the low (48: 0.35 ± 2.22; 72: 1.34 ± 5.6) and high dose condition (48: 1.34 ± 1.34; 72: -0.79 ± 5.34). Future investigations should consider implementing eccentric resistance training across a larger portion of the body to improve ecological validity of the exercise. A larger sample would reduce risk of researchers committing a type II statistical error and give strength to detecting differences between conditions

    Knowledge transfer within strategic partnerships: the case of HRM in the Brazilian motor industry supply chain

    Get PDF
    This paper investigates knowledge transfer (KT) of human resource management (HRM) across strategic partnerships in the Brazilian automotive industry, and the contextual factors impacting on KT within the supply chain. Case-study research in automotive companies and suppliers in Brazil is used to illustrate how in automotive industries, relationships with suppliers have traditionally been viewed as close, strategic partnerships, but over time, there has been a move towards more attenuated, supply chains, involving a shift towards more remote suppliers for basic components, and arms length relationships with them. In turn, this has impacted on how knowledge on HR has been transferred from manufacturers to suppliers. Both strategic partnerships and KT have been affected by internal drives towards cost cutting and talent retention, and external factors such as global competition through cheap imports, legislation, taxes, and unions. Evidence on the sometimes contradictory attitudes towards KT contributes towards the broader literatures on international HRM and KT in emerging economies, while the gradual unwinding of relationships has implications for policy and practice
