В статье представлен обзор существующих технических решений в сфере мониторинга и предотвращения апноэ во сне. Произведён анализ существующих аппаратов для предотвращения апноэ, который показал, что на рынке присутствует большое количество импортных моделей, однако они имеют довольно высокую цену. Разработанный нами Российский аналог проектируемого аппарата, при схожих характеристиках, будет иметь более привлекательную цену, чем у импортных приборов. Интегрирование датчика влажности в персональную маску пациента даёт возможность отслеживать остановки дыхания пациента во время сна, и тем самым включать процесс принудительной подачи дыхательной смеси именно в тот момент, когда она необходима для устранения патологии. Целью научной работы является разработка конструкции прибора и создание алгоритма программы для управления аппарата искусственной вентиляции лёгких для предотвращения апноэ во сне. Показана разработка структуры устройства аппарата. Подобран компрессор и датчик влажности с обоснованными характеристиками для создания аппарата, а также основные элементы. Разработана конструкция корпуса аппарата и разработана компоновка. Выполнено технико-экономическое обоснование разработки аппаратно-программного комплекса для предотвращения апноэ во сне. Показано, что себестоимость готового изделия достаточно конкурентна The article presents an overview of existing technical solutions in the field of monitoring and prevention of sleep apnea. An analysis of existing devices for preventing apnea was made, which showed that there are a large number of imported models on the market, but they have a fairly high price. The Russian analog of the designed device developed by us, with similar characteristics, will have a more attractive price than that of imported devices. The integration of the humidity sensor into the patient's personal mask makes it possible to monitor the patient's breathing stops during sleep, and thus enable the process of forced delivery of the respiratory mixture at the exact moment when it is necessary to eliminate the pathology. The purpose of the research is to develop the device design and create a program algorithm for controlling the artificial lung ventilation device to prevent sleep apnea. The development of the device structure is shown. The compressor and humidity sensor with reasonable characteristics for creating the device, as well as the main elements are selected. The design of the device body and its layout were developed. A feasibility study for the development of a hardware and software system for preventing sleep apnea has been completed. It is shown that the cost of the finished product is quite competitive

The Stability

The workpiece and tool vibrations in a lathe are experimentally studied to establish improved understanding of cutting dynamics that would support efforts in exceeding the current limits of the turning process. A Keyence laser displacement sensor is employed to monitor the workpiece and tool vibrations during chatter-free and chatter cutting. A procedure is developed that utilizes instantaneous frequency (IF) to identify the modes related to measurement noise and those innate of the cutting process. Instantaneous frequency is shown to thoroughly characterize the underlying turning dynamics and identify the exact moment in time when chatter fully developed. That IF provides the needed resolution for identifying the onset of chatter suggests that the stability of the process should be monitored in the time-frequency domain to effectively detect and characterize machining instability. It is determined that for the cutting tests performed chatters of the workpiece and tool are associated with the changing of the spectral components and more specifically period-doubling bifurcation. The analysis presented provides a view of the underlying dynamics of the lathe process which has not been experimentally observed before.

The link between military service and crime has been a subject of investigation for several decades. Although research has examined the likelihood of arrest, incarceration, and recidivism across military cohorts, relatively little is known about the circumstances surrounding police contact and suspect behavior at the exact moment of arrest. This is a critical oversight given that what transpires during an arrest can have a marked impact on downstream criminal justice outcomes, including access to diversionary programming like veterans treatment courts. Using a nationally representative survey of prison inmates, this study analyzes veteran and nonveteran self-reports of their arrest controlling for a host of relevant demographic, mental health, and criminal history variables. Findings indicate that veterans are significantly less likely to resist the police at arrest. These results provide further support to the sentiment that military culture and training can have a lasting behavioral influence on those who experience it.

Exact Moment

The so-called ‘anti-photian collection’ preserves a synthetic summary from the encomium to the Patriarch Ignatios composed by a certain Michael the Synkellos. The date of composition or the exact moment of its pronunciation are unknown, but it is possible that it was read on the anniversary of the Patriarch’s death or his burial in the Monastery of Satyros. Despite being a summary, the text conserves traces of the original rhetoric structure and, like a βίοςσὺνἐγκωμίῳ, it could be the model on which Nicetas David composed the Vita Ignatii. This article provides a new critical edition based on the most important manuscripts with exegetical notes

The One

The thesis of the commented judgement concerns issues which are significant in the practice of examining an application in the course of administrative court proceedings regarding a request for reinstatement of the deadline. The first is a need to settle the beginning of the term for submitting such a request, the second – the method of examining the application for reinstatement of the deadline in the event of the impossibility to determine whether the deadline for its submission has been met. In the jurisprudence, it is consonantly assumed that the formal condition of an application for the reinstatement of the deadline is that the circumstances justifying the admissibility of the application are plausible due to the observance of the one-week deadline for its submission from the date of expiration of the cause of the deadline failure. According to Art. 49 § 1 of the Act of 30 August 2002 – Law on proceedings before administrative courts, if the letter of a party cannot receive the correct course due to failure to observe formal conditions, the chairman shall request the party to supplement or correct it within seven days under pain of leaving the letter unprocessed. The Supreme Administrative Court reasonably decided that if the content of the application cannot infer an exact moment in which the cause of the deadline failure ceased to exist, it should be examined on the merits. Equally, there are no grounds for rejecting the application as belated, based on Art. 88 of the Law on proceedings before administrative courts, because the fact of submitting the application after the deadline cannot be presumed.

Santa Elena

The exact date on which the first Franciscan friars arrived in Cuba remains unknown, but it was certainly during an early phase of the conquest. Regardless of the exact moment in which the friars disembarked on the island, it is important to note that it marked the beginning of a long history, a history almost condemned to obscurity and from time to time the object of harsh criticism and impassioned indulgence, and more often recorded through partial constructions than through investigation and reasoning. Perhaps because of the complexity of its peculiarities and/or for certain socio-political determining factors that will not be analyzed at this time, Cuba has been one of the marginalized territories of the American ecclesiastical historiography. Nevertheless, in recent years, interest in ecclesiastical themes has grown incrementally among some scholars who, striving to fill the voids, have opened new lines of research and venture to investigate the older documents of the archive.
