Performance Analysis of Channels in Adiabatic and Non-Adiabatic Spiral Plate Heat Exchangers: A Thermodynamic Study
Authors: Sabouri Shirazi Amir Hossein , Ghodrat Maryam , Rastan Mohammad Reza , Salehi Fatemeh 
Published: December 2021

Abstract
This paper presents a systematic analysis of the thermodynamic performance of spiral turns in spiral plate heat exchangers (SPHEs), including non-adiabatic sources such as effects of heat leakage to the environment and fluid friction. These sources can reduce the thermal performance and increase the irreversibility of SPHEs. First, the critical factors of the heat loss rate to the environment, internal heat transfer rate (HTR), and channel temperature distributions are specified based on modeling the SPHE with hypothetical heat exchanger networks. Also, this modeling is validated with the results of channel temperature distributions by computational fluid dynamics simulation. Second, besides examining the spiral turns by entropy generation methods, entransy-based parameters are developed to analyze the SPHEs based on generated heat due to fluid viscosity in their channels for the first time. Finally, to show the method applicability proposed, an optimal designed single-phase counter-current SPHE is explored as a case. Three scenarios are introduced to evaluate the performance and irreversibility, namely heat leakage and no heat leakage to the environment and transferring the net heat between the streams. Results highlight the effects of non-adiabatic conditions, such as reductions of around 5.46%, 2.25%, and 2.42%, respectively, in the heat transfer area, total HTR, and overall heat transfer coefficient. Furthermore, findings confirm the performance reductions and irreversibility increments in non-adiabatic conditions and assert the importance of covering the outermost channels appropriately.

Published: December 2021

Abstract
This work presents a data-driven methodology for multi-objective optimization under uncertainty of process parameters in the fused filament fabrication (FFF) process. The proposed approach optimizes the process parameters with the objectives of minimizing the geometric inaccuracy and maximizing the filament bond quality of the manufactured part. First, experiments are conducted to collect data pertaining to the part quality. Then, Bayesian neural network (BNN) models are constructed to predict the geometric inaccuracy and bond quality as functions of the process parameters. The BNN model captures the model uncertainty caused by the lack of knowledge about model parameters (neuron weights) and the input variability due to the intrinsic randomness in the input parameters. Using the stochastic predictions from these models, different robustness-based design optimization formulations are investigated, wherein process parameters such as nozzle temperature, nozzle speed, and layer thickness are optimized under uncertainty for different multi-objective scenarios. Epistemic uncertainty in the prediction model and the aleatory uncertainty in the input is considered in the optimization. Finally, Pareto surfaces are constructed to estimate the tradeoffs between the objectives. Both the BNN models and the effectiveness of the proposed optimization methodology are validated using the actual manufacturing of the parts.

Objective. To evaluate the effect of admission hyperglycemia on the short-term prognosis of patients with non-ST elevation acute coronary syndrome (NSTE-ACS) without diabetes mellitus. Methods. The clinical data of 498 patients with NSTE-ACS admitted to the Department of Cardiology of the First Affiliated Hospital of Henan University of Science and Technology between March 2018 and November 2020 were analyzed. Based on the blood glucose (BG) level at admission, patients were divided into three groups: A (

BG
<
7.8

mmol/L), B (

7.8

mmol
/
L
≤
BG
<
11.1

mmol
/
L

), and C (

BG
≥
11.1

mmol/L). The clinical data of the three groups were compared. Results. There was no significant difference between the three groups in terms of age, sex, hypertension, hyperlipidemia, smoking, and history of myocardial infarction (

p
>
0.05

). However, there were significant differences in the incidences of multivessel disease, renal insufficiency, pump failure, and emergency percutaneous coronary intervention, and levels of high-sensitivity C-reactive protein, cardiac troponin T, and creatine kinase isoenzyme MB among the three groups (

p
<
0.05

for all). The incidences of severe pump failure, malignant arrhythmias, and death were significantly higher in groups B and C compared to group A (

p
<
0.05

). Additionally, the incidences of severe pump failure, malignant arrhythmias, and death were significantly higher in group C compared to group B (

p
<
0.05

). Multivariate logistic regression analysis showed that hyperglycemia, renal insufficiency, Killip grade III/IV, and age were risk factors of in-hospital death. Conclusion. Hyperglycemia at admission is a risk factor for adverse in-hospital clinical outcomes in patients with NSTE-ACS.
Early Form-Based Morphological Decomposition in Tagalog: MEG Evidence from Reduplication, Infixation, and Circumfixation

Published: December 2021

AbstractNeuro- and psycholinguistic experimentation supports the early decomposition of morphologically complex words within the ventral processing stream, which MEG has localized to the M170 response in the (left) visual word form area (VWFA). Decomposition into an exhaustive parse of visual morpheme forms extends beyond words like farmer to those imitating complexity (e.g., brother; Lewis et al., 2011), and to “unique” stems occurring in only one word but following the syntax and semantics of their affix (e.g., vulnerable; Gwilliams & Marantz, 2018). Evidence comes primarily from suffixation; other morphological processes have been under-investigated. This study explores circumfixation, infixation, and reduplication in Tagalog. In addition to investigating whether these are parsed like suffixation, we address an outstanding question concerning semantically empty morphemes. Some words in Tagalog resemble English winter as decomposition is not supported (wint-er); these apparently reduplicated pseudoreduplicates lack the syntactic and semantic features of reduplicated forms. However, unlike winter, these words exhibit phonological behavior predicted only if they involve a reduplicating morpheme. If these are decomposed, this provides evidence that words are analyzed as complex, like English vulnerable, when the grammar demands it. In a lexical decision task with MEG, we find that VWFA activity correlates with stem:word transition probability for circumfixed, infixed, and reduplicated words. Furthermore, a Bayesian analysis suggests that pseudoreduplicates with reduplicate-like phonology are also decomposed; other pseudoreduplicates are not. These findings are consistent with an interpretation that decomposition is modulated by phonology in addition to syntax and semantics.

Published: December 2021

Objective The study aims to investigate the potential of using HUD (head-up display) as an approach for drivers to engage in non–driving-related tasks (NDRTs) during automated driving, and examine the impacts on driver state and take-over performance in comparison to the traditional mobile phone. Background Advances in automated vehicle technology have the potential to relieve drivers from driving tasks so that they can engage in NDRTs freely. However, drivers will still need to take-over control under certain circumstances. Method A driving simulation experiment was conducted using an Advanced Driving Simulator and real-world driving videos. Forty-six participants completed three drives in three display conditions, respectively (HUD, mobile phone and baseline without NDRT). The HUD was integrated with the vehicle in displaying NDRTs while the mobile phone was not. Drivers’ visual (e.g. gaze, blink) and physiological (e.g. ECG, EDA) data were collected to measure driver state. Two take-over reaction times (hand and foot) were used to measure take-over performance. Results The HUD significantly shortened the take-over reaction times compared to the mobile phone condition. Compared to the baseline condition, drivers in the HUD condition also experienced lower cognitive workload and physiological arousal. Drivers’ take-over reaction times were significantly correlated with their visual and electrodermal activities during automated driving prior to the take-over request. Conclusion HUDs can improve driver performance and lower workload when used as an NDRT interface. Application The study sheds light on a promising approach for drivers to engage in NDRTs in future AVs.

Published: December 2021

The aim of the study was to assess the mental health burden of the COVID-19 pandemic in healthcare workers in four Latin American countries in 2020. An online survey was carried out with 1721 participants from Argentina, Chile, Colombia and Mexico in 2020. A non-probabilistic convenience sampling method was used to recruit voluntary participants. Post-traumatic stress symptoms were assessed with the SPRINT-E scale, Perceived Discrimination was assessed with a Spanish version of the scale developed by Molero, and anxiety toward death was assessed with the Spanish version of the Templer scale. All instruments were assessed for internal consistency. The overall frequency of post-traumatic stress symptoms was 23.9%. The frequency by countries was 26.4% in Argentina, 29.8% in Chile, 19.9 in Colombia, and 23.8% in Mexico. Post-traumatic stress symptoms were associated with individual subtle discrimination, anxiety toward the death of the elderly, lack of Personal Protective Equipment, and exposition to the death. The COVID-19 pandemic has imposed a mental health burden on health workers in the countries included in the study, not only due to the implications of the disease in the face of exposure to death, but also due to institutional conditions and in which they carry out their work.

Objective The advanced lung cancer inflammation index (ALI) predicts overall survival (OS) in patients with advanced lung cancer. However, few studies have tested ALI’s prognostic effect in patients with non-small cell lung cancer (NSCLC) following video-assisted thoracic surgery (VATS), especially patients at stage III. This study investigated the relationship between ALI and outcomes of patients with NSCLC following VATS. Methods We retrospectively examined 339 patients with NSCLC who underwent VATS at Hebei General Hospital, China. Preoperative clinical and laboratory parameters were collected and analyzed. Optimal cutoff values of potential prognostic factors, including ALI, were determined. Kaplan–Meier and Cox regression analyses were used to determine each factor’s prognostic value. Results The median OS was 31 months. The optimal cutoff value for ALI was 41.20. Patients with high ALI (≥41.20) displayed increased OS (33.87 vs. 30.24 months), higher survival rates, and milder clinical characteristics. Univariate and multivariate analyses showed a significant correlation between ALI and the prognosis of patients with NSCLC, including those at stage IIIA, who underwent VATS. Conclusions Low ALI correlated with poor outcomes in patients with NSCLC following VATS. Preoperative ALI might be a potential prognostic biomarker for patients with NSCLC following VATS, including patients at stage IIIA.

Published: December 2021

Background Early spasticity and dystonia identification in cerebral palsy is critical for guiding diagnostic workup and prompting targeted treatment early when it is most efficacious. However, differentiating spasticity from dystonia is difficult in young children with cerebral palsy. Methods We sought to determine spasticity and dystonia underidentification rates in children at high risk for cerebral palsy (following neonatal hypoxic-ischemic encephalopathy) by assessing how often child neurologists identified hypertonia alone versus specifying the hypertonia type as spasticity and/or dystonia by age 5 years. Results Of 168 children, 63 developed cerebral palsy and hypertonia but only 19 (30%) had their hypertonia type specified as spasticity and/or dystonia by age 5 years. Conclusions Child neurologists did not specify the type of hypertonia in a majority of children at high risk of cerebral palsy. Because early tone identification critically guides diagnostic workup and treatment of cerebral palsy, these results highlight an important gap in current cerebral palsy care.

Published: December 2021

Measures to contain the global COVID-19 pandemic led to stay-at-home orders across the world, accompanied by fears of a global surge in intimate partner violence (IPV). We administered an online general-population survey to 1169 women and transgender/nonbinary individuals throughout the state of Michigan in June–August 2020 to assess changes in the prevalence, severity, and correlates of IPV during the COVID-19 pandemic. Quota sampling was used to match the racial/ethnic and urban/rural distribution of the state. More than one in seven (15.1%) participants reported physical, sexual, psychological, or technology-facilitated IPV since COVID, similar to the prevalence in the 3 months before COVID (16.2%). However, there were indications that IPV severity increased and that novel cases of IPV are occurring in relationships that previously had no abuse. A majority (64.2%) of individuals who experienced IPV since COVID reported that the IPV was new to the relationship (34.1%) or of increased severity during COVID-19 (26.6%), representing 9.7% of the overall sample. New or increased IPV was significantly more prevalent among those who were essential workers, pregnant, unable to afford rent, unemployed/underemployed or had recent changes to their job, had partners with recent changes to employment, and those who had gotten tested or tested positive for COVID-19. Urban residence, trans/nonbinary identity, and having a toddler were more strongly associated with IPV during COVID as compared to before COVID. While findings do not support significant changes in the overall prevalence of IPV, the majority of survivors reported incident IPV in relationships that had not previously been abusive, or IPV that became more severe since the start of the pandemic. Cases of new or increased IPV were more concentrated in marginalized groups. Potential touchpoints for outreach and services during future lockdowns include prenatal and pediatric settings, daycares, employers of essential workers, and COVID-19 testing centers. Policies providing rental, childcare, and unemployment support may mitigate increases in IPV during COVID-19.
The Relationship Between Perceived Age Discrimination in the Healthcare System and Health: An Examination of a Multi-Path Model in a National Sample of Israelis Over the Age of 50
Authors: Ayalon Liat , Cohn-Schwartz Ella 
Published: December 2021

Objectives The present study aims to examine possible pathways that potentially account for the relationship between perceived age discrimination in healthcare settings (as one form of ageism) and health outcomes. Methods We relied on 1570 complete surveys, which constitute a representative national sample of adults aged 50 and above in Israel. Results We found a direct link between perceived age discrimination and health outcomes. This link was partially mediated by self-perceptions of aging and subsequently by health behaviors (e.g., eating vegetables) and preventive health behaviors (e.g., medical check-ups). The link between perceived age discrimination and health behaviors was moderated by age, thus, particularly detrimental for older people over the age of 65 as compared with those between the ages of 50 and 65. Discussion This study adds to the literature as it examines comprehensive mechanisms to account for the path between perceived age discrimination and health status. Our findings point to the unique aspects associated with perceived age discrimination, which potentially make older people more susceptible to its negative effects.

Published: December 2021

Objective To examine quality of life in internationally adopted children with cleft lip and/or palate (CL/P) versus non-adopted children with CL/P. Design Cross sectional study. Setting Multidisciplinary cleft team of a secondary and tertiary hospital in the Netherlands. Methods Parents of children under the age of 8 treated by the multidisciplinary cleft team of our institutions were asked to fill out a questionnaire containing demographic and clinical data and a validated parent proxy measure of cleft-specific quality of life instrument for children aged 0–8: the CleftChild-8. Adopted children were matched to non-adopted children using propensity score matching based on sex, age, type of cleft, if palatal surgery was completed and the level of education of the parent. CleftChild-8 scores were then compared between the matched samples of adopted and non-adopted children with CL/P. Main Outcome Measure(s) Differences in (sub)domain scores of the CleftChild-8. Results Most median CleftChild-8 scores of the adopted children (n = 29) were slightly lower compared to the 29 matched non-adopted children. A significant difference was seen for the domain score ‘satisfaction with (operative) treatment’ and 3 of the 13 subdomain scores: ‘post-operative results’, ‘acceptance by siblings’ and ‘acceptance by family/friends’. Conclusions By parent report, adopted children with CL/P experienced some areas of lower quality of life when compared to non-adopted children. Members of cleft teams should be aware of the problems associated with adoption and offer additional guidance and counseling to adopted children and their parents.
Small-scale multilingualism through the prism of lexical borrowing
Authors: Chechuro Ilia , Daniel Michael , Verhees Samira 
Published: December 2021

Aims and Objectives: We assess whether data on lexical borrowing obtained through field elicitation may point not only to a specific donor language but also to its specific regional variety, and whether these data are a reliable tool for reconstructing unknown historical patterns of interaction between ethnic subgroups. Methodology: We use quantitative analysis of the data obtained by loanword probing—elicitations of short wordlists from speakers of minority languages—to calculate the amount and identify the source of lexical transfer. We compare the results across several areas with varying degrees of bilingualism and different contact varieties of the donor language to see how this influences our results. Data: The data for this study come from a large-scale field study in Daghestan, with 72 people from 19 villages speaking four languages. Findings: Our method suggests that speech communities clearly indicate one of the regional varieties of Azerbaijani as the donor, depending on the area of data collection. We also observe that the degree of lexical convergence with the donor depends not only on the level of bilingualism observed in the specific village but also on the native language of this village, suggesting language borders as a natural constraint to the spread of lexical borrowing. Originality: The study is novel in that it is fully based on analysis of data on lexical convergence obtained through fieldwork on minority languages and provides quantitative results that can be compared across speech communities in the survey. Implications: We conclude that the method is sensitive enough to trace donorship to specific regional varieties of the donor language. Limitations: Our observations on the relative weight of the level of bilingualism and language affiliation of a speech community as predictors of the degree of lexical convergence require more data obtained both from other linguistic environments and by different methods.
Long-term care placement: The transitional support needs and preferences of spousal dementia caregivers

Published: December 2021

Background and objectives Many spousal caregivers experience stress, depression, loneliness, guilt and grief when placing a partner with dementia into long-term care. However, there is little research about their transitional support experiences, needs and preferences. This study aimed to gain a deeper understanding of these issues from spousal caregiver and long-term care facility staff perspectives, to inform subsequent support and intervention development. Research design and methods Semi-structured interviews and small group discussions were held separately with spousal caregivers ( n = 9) and care facility staff ( n = 11). Criterion and variation sampling aimed to ensure a range of experiences and perspectives. The ‘Framework’ approach was utilised for data analysis. Interpretation was with respect to underpinning models of stress-grief process in dementia caregiving. Findings A range of informational, psychoeducational and psychosocial supports were identified to help spousal caregivers cope better with the stressors and losses experienced throughout the transition from home to long-term care. Improved education about disease progression, information relating to long-term care provision, peer support and dementia-specific grief counselling were deemed important. Opportunities for better support within care facilities were also identified. Support should be tailored to individual needs and preferences. Discussion and implications The findings suggest a supportive care framework be developed, encompassing the trajectory from assessment for and admission into long-term care to end-of-life and post-bereavement support. Spousal caregivers should have their support needs assessed by trained health or social care professionals and be offered a range of support options as appropriate.
