    Get PDF
    When asked what sort of novel I was writing, I always said ‘a modern adventure novel’. And then I began to question myself about the meaning of these three words together, the substance and the definition of a modern adventure novel. Does such a thing exist? In my novel ‘Alexandre Goes South’, Alexandre is a thirty-year-old Parisian from a family that enjoy wealth and privilege, facts that provide a setting but play only incidental roles in the events that unfold. Alexandre goes through a series of crises, which propel the journey that launches him onto the road to manhood. The novel begins at the exact moment of suffering, after a break

    Robotic autonomous telescopes provide highlevel control by selecting astronomical targets for observation, and they usually run under the control of a scheduler. TalonVIEW is a newly designed robotic autonomous telescope control system (TCS) for 16 inches telescope mount for use in astronomical transient events. The telescope control algorithm was implemented in PXI chassis written in GProgramming (LabVIEW) on realtime operating system(PharLab) from scratch. A new TCP/IP library was also implemented in Talon software to communicate with Pharlab in PXI chassis. Initial setup without any permanent pier and polar alignment showed that the pointing error of the telescope has been obtained as 2.22 arcminutes (132 arcseconds) in RA axis (horizontal axis of the image) and 25 arcseconds in Dec axis (vertical axis of the image), and tracking error has been observed as 4.8 arcseconds per second

    Derailment-based fault tree analysis on risk management of railway turnout systems

    Get PDF
    Railway turnouts are fundamental mechanical infrastructures, which allow a rolling stock to divert one direction to another. As those are of a large number of engineering subsystems, e.g. track, signalling, earthworks, these particular sub-systems are expected to induce high potential through various kind of failure mechanisms. This could be a cause of any catastrophic event. A derailment, one of undesirable events in railway operation, often results, albeit rare occurs, in damaging to rolling stock, railway infrastructure and disrupt service, and has the potential to cause casualties and even loss of lives. As a result, it is quite significant that a well-designed risk analysis is performed to create awareness of hazards and to identify what parts of the systems may be at risk. This study will focus on all types of environment based failures as a result of numerous contributing factors noted officially as accident reports. This risk analysis is designed to help industry to minimise the occurrence of accidents at railway turnouts. The methodology of the study relies on accurate assessment of derailment likelihood, and is based on statistical multiple factors-integrated accident rate analysis. The study is prepared in the way of establishing product risks and faults, and showing the impact of potential process by Boolean algebra

    Investigation of the prevalence of impacted third molars and the effects of eruption level and angulation on caries development by panoramic radiographs

    Get PDF
    This study is aimed to determine the prevalence of impacted third molars and to investigate the effects of their eruption level and angulation on caries formation in the distal of the adjacent tooth. This cross-sectional study was conducted on panoramic radiographs of 38481 patients who were admitted to the Trakya University, Faculty of Dentistry. The panoramic radiographs of 7998 patients with at least one impacted third molar were included. Third molars were classified according to Winter?s classification and Pell and Gregory?s classification. The frequency of caries in partially impacted third molars and adjacent second molars was determined. The chi-square tests were used to determine potential associations between the third molars' level of eruption, angulation, and caries development. The study group consisted of 4423 females (55.3%) and 3575 males (44.7%) with a mean age of 36.3±13.4 years. The prevalence of the third molar impaction rate was 23%. The impaction pattern of partially erupted third molars was characterized by an eruption level of A with the vertical position in both jaws. Partially erupted and vertically placed maxillary third molars in the level of position A caused more caries in the adjacent tooth and mesioangularly located partially erupted mandibular third molars were associated with more caries in the adjacent tooth. The angulation and eruption level of partially erupted third molars should be carefully examined. The prophylactic extraction of vertically and mesioangularly located third molars, especially with an eruption level of position A can be suggested to eliminate the related complications and risk of caries

    Electrodermal Activity: Simultaneous Recordings

    Get PDF
    Electrodermal activity (EDA) is a sensitive measure of the sympathetic nervous system activity. It is used to describe changes in the skin electrical properties. This chapter aimed to show advantages of simultaneous recordings of EDA parameters at the same skin site over other recordings. The literature databases, Web of Science and Google Scholar, were searched using terms like “electrodermal activity,” “sequential recording,” “simultaneous recording,” “skin conductance,” “skin potential,” and “skin susceptance.” Articles that include sequential and/or simultaneous recording of EDA parameters were analyzed. The chapter presents a description of the oldest and current methods used for recording EDA parameters and an explanation of the newest techniques used in EDA researches. Although sequential recordings are predominant and widely spreading, much effort has been made to simultaneously record skin conductance (SC) and skin potential (SP), and recently researchers realized the capability of simultaneously recording SC, SP, and skin susceptance (SS) at the same skin site. The advantage of simultaneous over the sequence measurements is that the latter must be manually time realigned when measured by different instruments, which means it is time-consuming. Although the simultaneous measurements are used exclusively for research purposes at this stage, this may open horizons in the modern trends of psychophysiology applications in the near future

    In this study, it was aimed to examine the mindfulness-based self-efficacy levels of undergraduate students studying in sports sciences in terms of various variables. The sample of the research consists of undergraduate students studying at the faculty of sports sciences at Trakya University and Çanakkale Onsekiz Mart University, which were selected by convenience sampling method. The Conscious Awareness-Based Self-Efficacy Scale-Revised (SPS-A) developed by (Cayoun et al., 2012) and adapted into Turkish (Atalay et al., 2017) was used as a data collection tool in the research. The statistical information of the participants was evaluated by using the descriptive survey method in the study. Skewness and Kurtosis values were evaluated statistically by Normal Distribution test analysis. First of all, by looking at the Cronbach Alpha values of the scale, after the validity and reliability analysis, the skewness and kurtosis values of the obtained data were examined and the hypotheses of the socio-demographic variables were tested. Regular exercise status of students studying in sports sciences, taking part in sports organizations organized by university federations, having a licensed athlete for at least three years, according to the exam score taken as a basis for university application, according to the university success score, according to the frequency of participating in recreational activities, It was tested statistically according to the status of working in any job, university, department and class, and no significant difference was found in mindfulness-based self-efficacy, while a significant difference was obtained according to the gender variable. The result of Mann Whitney-U Test was obtained that male undergraduate students studying in sports sciences participating in the research had higher mindfulnessbased self-efficacy levels than females (P: 009<0.05)

    An evaluation of children with Kawasaki disease in Istanbul: a retrospective follow-up study

    Get PDF
    BACKGROUND: Kawasaki disease (KD) is an acute, self-limiting vasculitis of unknown etiology. The incidence of KD is increasing world wide. However, the epidemiological data for KD in Turkey has not been well described. OBJECTIVE: To describe the demographic, clinical, and laboratory features of children with KD who were diagnosed and managed in the American Hospital, Istanbul, Turkey. METHOD: Patients with KD were retrospectively identified from the hospital discharge records between 2002 and 2010. Atypical cases of KD were excluded. A standardized form was used to collect demographic data, clinical information, echocardiography and laboratory results. RESULTS: Thirty-five patients with KD, with a mean age of 2.5 + 1.9 years, were identified. Eighty-five point seven per cent of patients were under 5 years of age. A seasonal pattern favouring the winter months was noticed. In addition to fever and bilateral conjunctival injection, changes in the oral cavity and lips were the most commonly detected clinical signs in our cases. Coronary artery abnormalities were detected in nine patients. The majority of our patients had started treatment with intravenous immunoglobulin in the first 10 days of the onset of fever, and only one patient required systemic steroids for intravenous immunoglobulin-resistant KD. The coronary artery abnormalities resolved in all nine patients within 8 months. CONCLUSION: This study is the most comprehensive series of children from Turkey with KD included in Medline. As adult-onset ischemic heart disease may be due to KD in childhood, further prospective clinical investigations are needed to understand the epidemiology, management and long-term follow-up of the disease
