DEVICE FOR CHECKING AND CALIBRATING INDICATORS OF THE RESERVE TIME OF CONSCIOUSNESS PRESERVATION BY A PERSON IN CONDITIONS OF HYPOXIA

Для обеспечения надежного функционирования индикаторов резервного времени сохранения сознания человеком в условиях гипоксии разработан специальный прибор для их поверки и калибровки. Прибор включает регулятор давления, табло для индикации эталонного давления, табло для индикации резервного времени сохранения сознания, шланг с разъемом для соединения с датчиком барометрического давления, компрессор, регулятор давления и микропроцессор. Разработанный прибор обеспечивает возможность контроля работоспособности средств коллективного и индивидуального информирования экипажа пассажиров воздушных судов о величине предельного резервного времени сохранения сознания в чрезвычайных ситуациях высотных полетов. To ensure the reliable functioning of the indicators of the reserve time of consciousness preservation by a person in conditions of hypoxia, a special device for their verification and calibration has been developed. The device includes a pressure regulator, a tableau for indicating the reference pressure, a tableau for indicating the standby time of consciousness, a hose with a connector for connecting to the barometric pressure sensor, a compressor, a pressure regulator and a microprocessor. The developed device provides the ability to monitor the performance of the means of collective and individual informing the crew of aircraft passengers about the value of the maximum reserve time for maintaining consciousness in emergency situations of high-altitude flights.

The Role of Androgen Supplementation in Women With Diminished Ovarian Reserve: Time to Randomize, Not Meta-Analyze

The management of patients with diminished ovarian reserve (DOR) remains one of the most challenging tasks in IVF clinical practice. Despite the promising results obtained from animal studies regarding the importance of androgens on folliculogenesis, the evidence obtained from clinical studies remains inconclusive. This is mainly due to the lack of an evidence-based methodology applied in the available trials and to the heterogeneity in the inclusion criteria and IVF treatment protocols. In this review, we analyze the available evidence obtained from animal studies and highlight the pitfalls from the clinical studies that prevent us from closing the chapter of this line of research.

Analysis Of Youth Activities In The Digital Age: Time-Geographical Approach

The study analyses daily activities of youth in the virtual and actual environment within the framework of theoretical and applied achievements of time geography. The role of mobile devices in youth life, transformation of traditional activity and changes in the daily organization of actions due to digitalization are discussed. Empirical data for the research were obtained via a diary method (the respondents were 18–22-year-old students). Features of individual daily foreground and background activities, digital devices used, activities relation and localization are evaluated by geovisualization performed within the time-geographical concepts. Regardless of the smartphonization, individuals reserve time spans not associated with virtual activities; their online activities are localized within places of residence, study and traffic routes, while public spaces serve as “live communication” platforms (but a complete rejection of virtual activity does not occur here). An attempt to compare youth daily activity under ordinary conditions and during the period of forced isolation during the COVID-19 pandemic is being made.

TECHNOLOGIES OF AUTOMATED NOTIFICATION OF HUMAN HEALTH AND PERFORMANCE RISKS UNDER HYPOXIC HYPOXIA

The technologies of automated notification of health risks and human performance under hypoxic hypoxia are described, which provide the calculation and presentation in real time of visual and acoustic information about the value of the assessment of the reserve time for maintaining human health and performance under hypoxic hypoxia

It Is Best to Have a Policy About Cancelled and Missed Appointments, and to Enforce It Consistently

No business can run effectively and be profitable if customers do not pay for services offered. Mental health clinicians in private practice can easily go out of business if they repeatedly reserve time for clients that goes uncompensated. This chapter highlights how policies regarding cancelled and missed appointments are essential for the effective running of one’s practice. Yet, this chapter illustrates how rigidly enforcing these policies may backfire and result in harm to one’s practice and even in ethics and legal charges against the clinician. A thoughtful and sensitive approach for implementing these policies is provided. Guidance is offered on how to make decisions regarding the use of these policies and how their effective use may promote the success of one’s private practice. This chapter also explains how to effectively integrate the use of these policies into the ongoing informed consent process.

Joint optimization of economic production quantity and preventive maintenance with considering multi-products and reserve time

Purpose: We deal with the problem of the joint determination of optimal economic production quantity (EPQ) and optimal preventive maintenance (PM) for a system that can produce multiple products alternately. The objective is to find the optimal number of production cycles and the PM policy simultaneously by minimizing the cost model.Design/methodology/approach: Considering the products go through the system in a sequence and a complete run of all products forms a production cycle. In each cycle, beyond production time we also consider some reserve time for maintenance and setup, shortage and overproduction may occur. We study the integrated problem based on two PM policies, and explain the situation with the other PM policies. The delay – time concept is used to model PM decisions.Findings: Using the integrated EPQ and PM model, we can calculate the optimal production planning and PM schedule simultaneously, especially we consider multiple products in each production cycle, which is more practical and economic than previous works.Originality/value: In modern companies, the production planning and maintenance schedule share the same system, and traditional research about two activities is separated, that always generate conflicts, such as inadequate or excessive maintenance, and shortages, etc., so we develop the integrated EPQ and PM model to avoid these undesirable effects.
