Обогащение изотопом -=SUP=-15-=/SUP=-N атомарной компоненты азота в реакциях атомно-молекулярного обмена в послеразрядной зоне
Authors: Гуденко С.В. , Горшунов Н.М.
Published: February 2022

A kinetic model is presented that explains the more than thirty-fold enrichment of the atomic nitrogen component with the 15N isotope in the post-discharge zone. Isotopic enrichment is due to the activation nature of the exchange reaction of atoms with vibrationally excited nitrogen molecules, the upper vibrational levels of which are enriched with molecules containing a heavier isotope during non-equilibrium vibrational-vibrational exchange. The dependences of the concentrations of 14N and 15N atoms on the time of nitrogen flow through a quartz tube emerging from the region of a pulsed electric discharge are obtained. In addition to exchange, the model took into account the dissociation of molecules, the recombination of atoms, and the loss of the vibrational energy of molecules on the surface of the tube. The obtained dependence of the increase in the ratio of the concentrations of 15N to 14N atoms on the time of nitrogen flow through the post-discharge zone satisfactorily describes the experimental data published earlier and obtained in this work.

The research studies the interaction between subcooled small diameter water jet and thick steel heater at different surface temperatures, liquid velocities and jet angles. Although the heater surface temperature exceeded the Leidenfrost temperature and reached 340℃, the liquid, according to visual observations, wetted the surface. Geometrical characteristics of the heater surface wetted area and jet deflection angles were measured. It was hypothesised that jet deflection from the surface, accompanied by finely dispersed drops generation, occurs when thermal boundary layer, which develops in the liquid near the heater surface, reaches the liquid's outer surface. The preliminary measurements seem to confirm the hypothesis.

Published: February 2022

The microwave giant magnetoresistance effect in a (CoFe/Cu) superlattice with micron-sized holes has been studied. Measurements of the frequency dependences of the transmission coefficient, as well as the dependences of the microwave transmission and reflection coefficients on the magnetic field, are performed. The measurements were performed on the superlattice samples without holes, having one hole with a diameter of 6.3 m and seven holes with a diameter of 1.7 m. It is shown that the presence of a hole with a diameter of 6.3 m leads to a significant frequency dependence of the microwave giant magnetoresistance effect. Magnetic and magnetoresistance measurements of superlattice samples were performed.

Authors: Pindeh Naincie , Kamaruddin Azrina , Norowi Noris Mohd , Rahmat Rahmita Wirza O.K
Published: February 2022

BACKGROUND

Exergames, also known as exertion games, is a compelling approach aimed at making exercise a pleasant experience on top of improving sedentary lifestyles. Older adults are among the least physically active individuals in the general population. Many researchers have reported the effectiveness of exergame applications as evidence to promote various forms of physical activity among older adults.

OBJECTIVE

This review set out to identify studies related to the use of exergames interventions with the aim of promoting physical activity and decreasing sedentary lifestyles in older adults. We also aimed to provide a summary of the current trends and future directions of exergames for older adults.

METHODS

A systematic review was conducted to retrieve relevant articles published between 2015 and 2021 in the Cochrane Library, Pubmed, IEEE, Science Direct, ACM Digital Library, SCOPUS, Mary Ann Liebert, Taylor & Francis Online, Wiley Online Library, Springer, and SAGE databases. The review followed the guidelines in the PRISMA Statement (Preferred Reporting Items for Systematic Reviews).

RESULTS

A total of 19 studies were found to be eligible for this review. The results showed that exergames significantly increased the level of physical activity among older adults. We also outlined the directions for future research on the use of exergames as a health and fitness strategy to ensure a high level of physical activity for older adults.

CONCLUSIONS

This systematic review showed that exergames interventions are beneficial in encouraging high levels of physical activity and to minimise sedentary lifestyles among older adults.

Published: February 2022

BACKGROUND

Automated acquisition of intraoperative patient temperature data by temperature probes leads to the possibility of incurring a number of artifacts related to probe positioning that may impact their utility for observational research.

OBJECTIVE

We sought to compare the performance of two de-novo algorithms to filter such artifacts.

METHODS

In this observational retrospective study intraoperative temperature data of adults who received general anesthesia for non-cardiac surgery were extracted from the Multicenter Perioperative Outcomes Group (MPOG) registry. Two algorithms were developed and were then compared to the reference standard of anesthesiologists’ manual artifact detection. Sensitivity and specificity for artifact detection were calculated for each algorithm, as were mean temperatures and Area Under the Curve (AUC) for hypothermia (below 36C) for each patient after artifact removal by each methodology.

RESULTS

A total of 27,683 temperature readings from 200 anesthetic records were analyzed. The overall agreement among the anesthesiologists was 92.1%. Both the algorithms had high specificity but moderate sensitivity (Specificity- Algorithm 1: 99.02 % vs. Algorithm 2: 99.54%; Sensitivity- Algorithm 1: 49.13% vs. Algorithm 2: 37.72%, F-score- Algorithm 1: 0.65 vs. Algorithm 2: 0.55). The timeX temperature hypothermic Area Under 36.0 degrees and the mean temperature per case after artifact removal were similar between the algorithms and the anesthesiologists.

CONCLUSIONS

The tested algorithms provide an automated way to filter intraoperative temperature artifacts which closely approximate manual sorting by anesthesiologists.Our study provides evidence demonstrating the efficacy of a highly generalizable artifact reduction algorithm that can be readily employed by observational studies that rely on automated intraoperative data acquisition.

Triage errors are a major concern in health care due to resulting harmful delays in treatments or inappropriate allocation of resources. With the increasing popularity of digital symptom checkers in pre–primary care settings, and amid claims that artificial intelligence outperforms doctors, the accuracy of triage by digital symptom checkers is ever more scrutinized. This paper examines the context and challenges of triage in primary care, pre–primary care, and emergency care, as well as reviews existing evidence on the prevalence of triage errors in all three settings. Implications for development, research, and practice are highlighted, and recommendations are made on how digital symptom checkers should be best positioned.

The Representation of Indonesian National Identity in English Textbook
Authors: Masita Ella
Published: February 2022

This article interrogates the conceptualization of Indonesian national identity from the point of view of the Indonesian government. The data were taken from a mandatory English textbook for Grade XI. Through the lens of Representation theory, this research explores the key issues within the textbook. In analyzing the data, a multimodal discourse analysis is utilized, specifically through the verbal analysis and visual analysis of the texts within the textbook. The results of analysis reveal that there are four themes namely: spirituality and morality, personal attribute, nationalism, and knowledge and scientific attitude. However, the research results indicate the inclusion of selected values and norms of personal attributes, the unbalanced portion of the themes within the textbook and minimal representation of the knowledge development, specifically in regards to the development of English skills. Apart from that, it is realized that textbook is only one part of elements in English teaching process. Therefore, further studies with a broader scope of investigation are required to achieve more comprehensive information about how Indonesian national identity in conceptualized in English teaching.
