Three-dimensional roll-up of a viscoelastic mixing layer

In this paper, the three-dimensional roll-up of a viscoelastic mixing layer is numerically simulated with the pseudospectral method using the FENE-P model. An artificial diffusion is self-adaptively introduced into the constitutive equation to stabilize the time integration. In the three-dimensional mixing layer and within the parameter ranges studied, the effect of the polymer additives on the formation of the coherent structures such as the ribs and the cups is found to be negligible. The polymer normal stresses develop wherever there exist extensional strains that are produced by the coherent structures and they then hinder the development of these structures. Stretching by the quadrupoles and the ribs together gives rise to an enormous enhancement of the polymer normal stress differences in the symmetrical plane between the quadrupole pair. These normal stress differences directly or indirectly weaken all large-scale structures occurring in the flow including the quadrupoles, the cups, the ribs, the spanwise vortices which rotate in the opposite direction to that of the cups, and the thin spanwise vortical sheets. Attenuation of these large-scale structures leads to a diminution of small-scale structures after their breakdown in the secondary roll-up process of the thin sheets. There is a tendency for the small-scale structures in the core region to merge into a large-scale one in the viscoelastic case. As a result, a flat and inclined vortex forms at the end of the simulation which resembles the type of structure observed in an experimental mixing layer with surfactants injected. In addition, the results show that the extensional viscosity is an important quantity to determine the extent to which the coherent structures in a mixing layer are modified by polymer additives.
Effects of precipitation on propagation at 0.63, 3.5, and 10.6 microns

The attenuation and scattering of laser beams by rain, fog, and snow have been calculated and measured at 0.63, 3.5, and 10. 6μ. Attenuation of the infrared wavelengths by light fog is up to one order of magnitude less than at 0.63μ. But for dense fog, calculation shows that the attenuation at 10. 6μ can exceed 40 dB per km. It is found that attenuation by rain can be calculated to good accuracy from average path rain rates provided that forward scattering is taken into account; this scattering reduces the attenuation. Measurements of propagation through precipitation over a 2.6 km path are discussed in detail and are found to be consistent with predictions. The wavelength dependence of attenuation is found to vary from one fog to another because of different drop-size distributions. Attenuation of 0.63μ in rain showers is about 20 per cent less than at 3.5μ and is, of course, much less than the attenuation in fog. But even for extremely heavy rain showers, the 0.63μ attenuation never exceeded 20 dB per km, which is less than the attenuation of millimeter waves under such conditions. Both the attenuation and foreward scattering properties of snow appear to be between those of fog and rain.
Efficacy and safety of antivirals in treating hearing loss: A systematic review and network meta-analysis

Objectives This study aimed to compare and rank the therapeutic effects of antivirals in treating hearing loss using a network meta-analysis approach. Methods We searched the PubMed, Embase, and Cochrane Library databases to identify eligible randomized controlled trials (RCTs) through April 2022. Placebo-controlled or head-to-head RCTs of three categories of antivirals for hearing loss were included, and pooled relative risks (RRs) with 95% confidence interval (CI) were calculated using pairwise and network meta-analyses. Results Six RCTs with 405 patients were included in the final analysis. The results showed that ganciclovir had relatively better effects on the incidence of hearing recovery (surface under the cumulative ranking: 88.8%) compared with other antivirals. However, pairwise comparison analyses found that the use of antivirals significantly increased the incidence of hearing recovery compared with the use of a placebo (RR: 1.27; 95% CI: 1.04–1.54; P = 0.017), while no significant difference was observed between any two categories of antivirals. Finally, the use of antivirals did not increase the risk of adverse events compared with the use of a placebo (RR: 1.27; 95% CI: 0.82–1.98; P = 0.285). Conclusion Antivirals are more efficacious than placebos for hearing recovery in patients with hearing loss, and ganciclovir is the most likely to increase the incidence of hearing recovery.
Professional Reflexivity in Thai Teachers’ Understanding of Asperger’s Syndrome

Introduction. The aim of this research is to investigate changes in Thai educators’ attitudes towards their understanding of Asperger’s Syndrome before and after a teacher-training session. Currently, opportunities for professional training regarding Asperger’s Syndrome are very scarce in Thai educational communities. Educators may not be able to provide optimum education and guidance for their students with Asperger’s Syndrome. Meanwhile, these students’ learning outcomes are significantly affected by their educators lacking knowledge of evidence-based intervention methods. Therefore, based on a needs assessment, a teacher-training session was developed to minimize the gaps in pedagogical knowledge and practice. Materials and Methods. A quasi-experimental, embedded mixed-methods design was used to obtain data. This study employed a one-group, pre-test/post-test design, as there were no control groups involved due to the novel learning subject matter. The limitations of the current study – its structure and participant recruitment – were identified and discussed. An availability sampling method was used for this study, resulting in the recruitment of 12 in-service teachers and 32 pre-service teachers from the northeastern region of Thailand. Questionnaires and interviews were used as measurement tools to comprehensively capture participants’ learning experiences. For the statistical analysis, the paired sample t-test (alpha = .05) was used. Meanwhile, for the descriptive analysis, the deductive approach was used. Results. Our results corroborate our sequential hypotheses regarding a teacher-training session and educators’ perceived levels of understanding of Asperger’s Syndrome. The training session was developed with a hypothesis that teachers needed educational opportunities to acquire proper knowledge of Asperger’s Syndrome, so that their students could be fully benefited from the pedagogy. As a result of attending the session, a statistically significant increase in correct response rates was indicated. Indeed, this increase in knowledge fulfilled the second hypothesis that by having proper knowledge of Asperger’s Syndrome, teachers’ professional reflexivity can be improved. Discussion and Conclusion. The outcomes of this study indicate that a teacher-training session has played a crucial role in cultivating Thai educators’ understanding of Asperger’s Syndrome. The outcomes present an interesting correlation between teachers’ knowledge acquisition and their increased professional and personal reflections. Simultaneously, the findings of this study suggest the potential benefits of improving research methodology, including an employment of randomized control trial, a larger sample size, and diversity within the sample population.
Association between sleep patterns, somatization, and depressive symptoms among Russian university students

ABSTRACT In adolescents and young adults, physical and mental health are known to be associated with sleep. In this paper, we consider the connection between health indicators and sleep patterns. We collected and analyzed data of 267 master’s and bachelor’s degree students from 21 educational programs at one elite Russian university. Somatic health and mental health were measured using, respectively, the 8-item and the 15-item Patient Health Questionnaire, and sleep patterns were identified using the Munich Chronotype Questionnaire. The results indicated that shorter sleep time, later bedtime, and later rising time on workdays were associated with student somatic health. Shorter sleep on workdays was positively associated with the severity of depressive symptoms. Our findings highlight the importance of healthy sleep behavior for student health.
Equilibrium in a stochastic $n$-person game

Heuristically, a stochastic game is described by a sequence of states which are determined stochastically. The stochastic element arises from a set of transition probability measures. The determination of the particular transition probability measure to be used at a move of the game is controlled in part by each of the n players and it is this determination scheme which gives rise to the strategies. One might consider the following economics problem. We have n firms competing for a market. Each will make a strategy decision periodically. During each period the n firms play an ? z-person game. Across the infinite horizon then we have a sequence of games. The economic situation behaves in such a way that the game played in a given period depends on the game played in the previous period and the strategies used in this period. The dependence is not deterministic but is stochastic. A player's strategy will reflect a concern both for the game now being played and for the situation that will be probably confronted in the next period. The relative strength of these two concerns will be in a geometric ratio, the so-called discounting over the infinite horizon. We shall call the outcome of each game a cost to each player. Negative cost is thus a gain. More precisely we are considering a game which is described by a finite set of states /. A play is a sequence of states {/»}£= 0> &' » 6 1 Ή the game is in the state /, each player h may choose an alternative jh eJ (Γ). This choice is made with knowledge of the state ί. Once each player has made his choice, the game proceeds to the state fe with probability PH^. J^ Here Fίy1. ;w^>0 and ^Pijr.jnk = 1. The cost to player h of being in state ί and having the vector ; = (/ι, ••-, /Λ) chosen is ChΓj. Each player furthermore chooses to discount his projected cost by a factor αΛ, where 0 < α Λ < l . Thus if a sequence of states {ίn} and alternative choices {]n} have been made, the cost to player h is given by
The impact of ergonomic practices on housekeeping employee retention and efficiency in hotels during COVID-19 in India

This article explores the current status of housekeeping-employee retention and efficiency in hotels particularly during COVID-19 in India, then discusses the implications of ergonomic practices on these. Ergonomic practice research in hotel housekeeping has been given enlarged scholarly attention, yet similar research in the Indian context is almost non-existent. Housekeeping work involves considerable physical effort that can lead to discomfort or even injury. This research involved 210 housekeeping employees from five-star hotels through an online survey. The data were interpreted using the partial least square (PLS) software SmartPLS 2.0. The constructs used in the study were working conditions, risk assessment and control, pandemic response plan, employee efficiency and employee retention. Working conditions were found to have a significant positive relationship with employee retention, whereas, risk assessment and control was found to have a positive relationship with employee retention and employee efficiency. Also, the pandemic response plan was found to have a positive relationship with employee efficiency. The pandemic response plan was not found to have a significant positive relationship with employee retention, while working conditions were not found to have a significant positive relationship with employee efficiency either.
Frequency of swallowing and food complaints during shared consultation in oncological palliative care

ABSTRACT Purpose to identify the frequency of swallowing and feeding complaints in cancer patients in palliative care, and to associate them with clinical and functional data. Methods cross-sectional and descriptive study, carried out with cancer patients treated during shared consultation in a palliative care outpatient clinic, through speech-language pathology screening, protocols and scales, with statistical analysis of the obtained data. Results Sample consisted of 52 subjects, seen during 8 months, with a mean age of 66.7 years, PSS (Palliative Performance Scale) a mean of 57.5. The topography of the most frequent neoplasm was the gastrointestinal tract and the treatment was surgery and associated chemotherapy and radiotherapy . Complaints identified at screening were categorized into swallowing and feeding. Thus, swallowing was the most frequent and a large part of the sample required a functional assessment of swallowing. Only the association between swallowing complaints and the topography of the gastrointestinal tract showed a significant statistical relationship. Swallowing complaints were more frequent in those undergoing radiotherapy and with lower percentages on the PPS scale. Conclusion swallowing complaints were the most frequent and the associations made it possible to relate them to the location of the tumor, and to identify their frequency according to cancer treatment and terminal functional decline.
Epidemiology of poisoning in Syria (1999 through 2020)

Abstract Introduction Acute poisoning is a significant international public health issue and one of the leading causes of death in the emergency department (ED). In the absence of any previous reports describing the poisoning profile in Syria, we present this study to assess the epidemiological and clinical characteristics of poisoning over 21 years. Methods We collected the data retrospectively from the Syrian Poisons Information Centre (SPIC) from January 1999 until December 2020. The data included patients who had accidental or non-accidental exposure to poisons, either by drugs, medicaments, and biological substances or substances chiefly nonmedicinal sources such as soaps and detergents, corrosive substances, pesticides, and other miscellaneous products. Results We collected the data of 120,972 poisoned patients, of whom 52.6% were females, and 47.4% were males. Aleppo governorate reported the highest number of poisoned cases (28.6%), followed by Damascus governorate (19.9%). The highest poisoning rates were recorded in 2020, 2014, and 2010. Pharmaceutical (37.0%) and animal (33.8%) sources were the most common causative agents. The oral route was the route of poisoning in 58.3% of patients, and 33.4% through the skin. The most common poison was scorpion stings 19.5% while the most common cause of death was organophosphates 15.7%. Discussion The differences in socioeconomic status, cultural habits, and agricultural and industrial activities between countries have led to a state of fluctuation regarding the most common poisoning agents. Conclusion Damascus and Aleppo, the two major governorates in Syria, had the highest poisoning cases. Oral administration of pharmaceutical agents was responsible for most of the poisoning cases. The most common individual poison was the scorpion poison, while the top killer was organophosphates.
A geometric interpretation of the relations between the exponential and generalized Erlang distributions

Linear combinations of exponential distribution functions are considered, and the class of distribution functions so obtainable is investigated. Convex combinations correspond to hyperexponential distributions, while non-convex combinations yield, among other, generalized Erlang distributions obtainable as sums of independent exponential random variables with different parameters. For a given number n of different exponential distributions, the class investigated is an (n – 1)-dimensional convex subset of the n-dimensional real vector space generated by the n distribution functions. The geometric aspect of this subset is revealed, together with the location of hyperexponential and generalized Erlang distributions.
Evaluation of image deblurring methods via a classification metric

The performance of single image deblurring algorithms is typically evaluated via a certain discrepancy measure between the reconstructed image and the ideal sharp image. The choice of metric, however, has been a source of debate and has also led to alternative metrics based on human visual perception. While fixed metrics may fail to capture some small but visible artifacts, perception-based metrics may favor reconstructions with artifacts that are visually pleasant. To overcome these limitations, we propose to assess the quality of reconstructed images via a task-driven metric. In this paper we consider object classification as the task and therefore use the rate of classification as the metric to measure deblurring performance. In our evaluation we use data with different types of blur in two cases: Optical Character Recognition (OCR), where the goal is to recognise characters in a black and white image, and object classification with no restrictions on pose, illumination and orientation. Finally, we show how off-the-shelf classification algorithms benefit from working with deblurred images.
FREE VIBRATIONS OF CIRCULAR PLATES COUPLED WITH LIQUIDS: REVISING THE LAMB PROBLEM

This paper deals with the analytical and numerical approaches used to estimate the natural frequencies of circular plates in contact with a liquid. The circular plate is assumed to be in contact with a liquid on one side and placed into the hole of an infinite rigid wall; this is the problem studied by Lamb. The change in natural frequencies is first calculated using the so-called nondimensional added virtual mass incremental (NAVMI) factor which reflects the increase of kinetic energy due to the liquid. The analytical expression of NAVMI factors for circular plates possessing axisymmetric boundary conditions is obtained. The more accurate Rayleigh-Ritz solution of the problem is then taken and compared to the results obtained by using the NAVMI factors. Numerical data is given for both free-edge, simply supported and clamped plates and for supported plates with an elastic moment edge constraint.
The contribution of teacher, parental and peer support in self-reported school and general well-being among ethnic-cultural minority and majority youth

Social support has been shown to be a crucial element in the well-being of children and adolescents. The present research article investigated how various sources of social support (i.e., parental support, teacher support and peer support) are related to school well-being and general well-being,. A survey was administered to N = 12,215 primary school pupils, pertaining to three ethnic-cultural groups, i.e., the national majority group, the Eastern European minority group and the Middle Eastern minority group. The results showed that perceived teacher support was most strongly and positively related to school well-being, although peer support was also an important determinant of school well-being. All three sources of perceived support were positively related to general well-being. Furthermore, and contrary to previous research, no significant differences were found between both minority groups and the national majority in terms of perceived teacher support. Conversely, both minority groups reported lower perceived parental and peer support. It was further shown that minority status moderated the relationship between the various sources of support and school well-being, although it should be articulated that these effects sizes were fairly small. School diversity, finally, did not yield any relevant effects. Similarities and differences with the existing literature on school well-being are delineated, and potential explanations for these divergences are discussed.
Flash-assisted Deep Mixing in Globular Cluster Red Giants

We discuss a new model of deep mixing in red giants caused by shell flashes triggered by the inward penetration of hydrogen into the helium core. The objective is to explain the large star-to-star variations of proton-capture elements that are observed among globular cluster red giants (Fujimoto, Aikawa, & Kato). The characteristics of this mixing model are explored by computing the products of nucleosynthesis during hydrogen shell flashes in red giants. It is shown that, during sufficiently strong flashes, both 24Mg and 23Na are depleted by burning. For moderately and very metal-poor clusters, the burned 24Mg is converted mostly into 27Al. Thus, the model not only resolves the difficulties arising from the observed underabundance of 24Mg, but also removes the problem of sodium overproduction, which would otherwise accompany the aluminum enrichment observed. For moderately metal-poor cluster giants, 25Mg and 26Mg survive with nearly scaled-solar abundances, while for very metal-poor cluster giants, all the magnesium isotopes are depleted and aluminum also burns appreciably into 28Si. For metal-rich cluster giants, shell flashes are quenched before 25Mg and 26Mg can burn to synthesize aluminum. These properties agree well with the manner in which observed abundance anomalies vary with cluster metallicity, including the absence of large Al-enrichments for red giants in metal-rich clusters. From a detailed comparison with observed abundances in M13 giants, we deduce constraints on the strength of the mixing mechanism responsible for the inward penetration of hydrogen into the helium core. We discuss further implications of the present results, in particular the importance of star-star interactions for the proper understanding of the evolution of stars in globular clusters.
Analyzing Designed Experiments with Multiple Responses

Abstract This paper is an overview of a unified framework for analyzing designed experiments with univariate or multivariate responses. Both categorical and continuous design variables are considered. To handle unbalanced data, we introduce the so-called Type II* sums of squares. This means that the results are independent of the scale chosen for continuous design variables. Furthermore, it does not matter whether two-level variables are coded as categorical or continuous. Overall testing of all responses is done by 50-50 MANOVA, which handles several highly correlated responses. Univariate p-values for each response are adjusted by using rotation testing. To illustrate multivariate effects, mean values and mean predictions are illustrated in a principal component score plot or directly as curves. For the unbalanced cases, we introduce a new variant of adjusted means, which are independent to the coding of two-level variables. The methodology is exemplified by case studies from cheese and fish pudding production.
