Low cycle fatigue performance of DP900 steel under cyclic shear paths
Authors: Zhang Zhongran , Yue Zhenming , Qi Jiashuo , Gao Jun , Qiu Yuliang 
Published: October 2021

AbstractIn this study, a sheet fatigue shear test device is designed and applied to the low‐cycle fatigue testing of DP900 with varying strain amplitudes within the range of 0.5%–6.0%. The microstructure is analyzed by using electron backscatter diffraction, and fracture surfaces are examined via scanning electron microscopy. Results indicate that the material exhibits cyclic softening behavior after the first two cycles of hardening, with a stable softening rate and a high damage evolution rate related to loading amplitude. The variation of the hysteresis curve in the cyclic process is shown. Total plastic strain energy absorbed increases as loading amplitude decreases and it reaches the peak at approximately 1%. The life prediction model based on plastic strain energy density and strain amplitude is verified to be suitable for the cyclic shear path. The influence of microinhomogeneity on the distribution of stress and strain, especially the deformation of martensite, is closely related to the bi‐linear region of fatigue life curve.
Investigation of creep damage mechanical behaviors of red sandstone considering temperature effect
Authors: Pan Xiaokang , Berto Filippo , Zhou Xiaoping 
Published: October 2021

AbstractThis work investigates the influence of high temperature on the creep damage behaviors of red sandstone. The closure and evolution of microcracks in the red sandstone treated at different temperatures during the enter creep process are analyzed. Temperature has obvious influence on uniaxial compressive strength, Young's modulus, and failure modes of red sandstone. It can degrade the mechanical behaviors of red sandstone and can reduce the ability of red sandstone to resist creep deformation. Moreover, acoustic emission (AE) technology is employed to monitor the distribution law of the AE events generated at each creep stage. As the temperature increases, the absolute value of the critical index increases exponentially, reflecting the exponential increase in the proportion of its low‐energy AE signal.

AbstractThe pollution of the marine environment with microplastics is pervasive. However, microplastic concentrations in the seawater are lower than the number of particles entering the oceans, suggesting that plastic particles accumulate in environmental sinks. Yet, the exact long‐term sinks related to the “missing plastic” phenomenon are barely explored. Sediments in nearshore biogenic habitats are known to trap large amounts of microplastics, but also the three‐dimensional structures of coral reefs might serve as unique, living long‐term sinks. The main framework builders, reef‐building corals, have been shown to ingest and overgrow microplastics, potentially leading to a deposition of particles in reef structures. However, little is known about the number of deposited particles and the underlying processes determining the permanent deposition in the coral skeletons. To test whether corals may act as living long‐term sink for microplastic, we exposed four reef‐building coral species to polyethylene microplastics (200 particles L−1) in an 18‐month laboratory experiment. We found microplastics in all treatment specimens, with low numbers of particles trapped in the coral tissue (up to 2 particles per cm2) and much higher numbers in the skeleton (up to 84 particles per cm3). The numbers of particles accumulated in the coral skeletons were mainly related to coral growth (i.e., skeletal growth in volume), suggesting that deposition is a regularly occurring stochastic process. We estimate that reef‐building corals may remove 0.09%–2.82% of the bioavailable microplastics from tropical shallow‐reef waters per year. Our study shows for the first time that microplastic particles accumulate permanently in a biological sink, helping to explain the “missing plastic” phenomenon. This highlights the importance of coral reefs for the ecological balance of the oceans and reinforces the need to protect them, not only to mitigate the effects of climate change but also to preserve their ecosystem services as long‐term sink for microplastic.

Authors: Evans Randolph W. , Turner Dana P. 
Published: October 2021

AbstractObjectiveTo describe the clinical features of new daily persistent headache (NDPH) at an outpatient neurology clinic with a subspecialty interest in headache in Houston, Texas.MethodsA retrospective chart review was performed by a neurologist subspecialty certified in headache medicine of all patients seen from September 1, 2011 through February 28, 2020 (8.5 years) with a provisional diagnosis of NDPH and abstracted charts meeting criteria for primary NDPH.ResultsA total of 328 patients met the International Classification of Headache Disorders, 3rd edition criteria including 215 (65.5%) female patients. The mean age of onset was 40.3 years (range 12–87 years) with a mean age at first consultation in the study clinic of 42.6 years (range 12–87 years). The median [25th, 75th] duration of NDPH at initial consultation was 0.7 [0.3, 2.0] years, and at last visit, it was 1.9 [0.7, 4.8] years. The headaches were side‐locked unilateral in 28/328 (8.5%). 12/328 cases (3.6%) with a thunderclap onset are reported. There was no obvious seasonal or other cyclical variation. The pain was usually moderate to severe and more often severe for the migraine phenotype (MP; 260/328 [79.3%] of cases) than for the tension‐type phenotype (TTP). Precipitating factors were the following: stressful life events, 67/328 (20.4%); upper respiratory infection or flu‐like illness, 33/328 (10.1%); and extracranial surgery, 5/328 (1.5%). Exacerbating or aggravating factors similar to migraine triggers were more often reported with the MP than with the TTP in this sample. For the MP, vertigo or dizziness was reported by 19/260 (7.3%) and a visual aura by 21/260 (8.1%) with descriptions provided. The prognostic types were the following for all patients: persisting (refractory), 305/328 (93.0%); relapsing–remitting, 9/328 (2.7%); and remitting (self‐limited), 14/328 (4.3%).ConclusionNDPH is typically of moderate to severe intensity often with migraine features without obvious seasonal or other cyclical variation. Most cases are refractory. 3.6% have a thunderclap onset often with a good response to treatment.

AbstractPurposeThe aim of this study was to develop a patient decision aid (pDA) that could support patients with breast cancer (BC) in making an informed decision about breast reconstruction (BR) after mastectomy.MethodsThe development included four stages: (i) Establishment of a multidisciplinary team; (ii) Needs assessment consisting of semi‐structured interviews in patients and a survey among healthcare professionals (HCPs); (iii) Creation of content, design and technical system; and (iv) Acceptability and usability testing using a think‐aloud approach in patients and interviews among HCPs and representatives of the Dutch Breast Cancer Patient Organization.ResultsFrom the needs assessment, three themes were identified: Challenging period to make a decision, Diverse motivations for a personal decision and Information needed to make a decision about BR. HCPs valued the development of a pDA, especially to prepare patients for consultation. The pDA that was developed contained three parts: first, a consultation sheet for oncological breast surgeons to introduce the choice; second, an online tool including an overview of reconstructive options, the pros and cons of each option, information on the consequences of each option for daily life, exercises to clarify personal values and patient stories; and third, a summary sheet with patients’ values, preferences and questions to help inform and guide the discussion between the patient and her plastic surgeon. The pDA was perceived to be informative, helpful and easy to use by patients and HCPs.ConclusionConsistent with information needs, a pDA was developed to support patients with BC who consider immediate BR in making an informed decision together with their plastic surgeon.Patient or Public ContributionPatients participated in the needs assessment and in acceptability and usability testing.
DISTRIBUTIONAL AND HOUSING PRICE EFFECTS FROM PUBLIC TRANSIT INVESTMENT: EVIDENCE FROM VANCOUVER
Authors: Chernoff Alex , Craig Andrea N. 
Published: October 2021

AbstractWe estimate a residential sorting model using microdata to study an expansion of the Vancouver rapid transit network. Our results indicate that many aspects of household preferences were stable over time; however, preferences for transit access became more homogeneous with respect to income. Simulations show that these preference changes, along with endogenous housing appreciation and rising income levels in connected neighborhoods, result in larger benefits for higher‐income households. This distributional pattern is driven by the gains of households working in pre‐connected neighborhoods. In contrast, the benefits to those working in newly connected neighborhoods disproportionately favor lower‐income households.

Published: October 2021

SummaryThere was an extensive interest in food‐grade Pickering emulsions formulated by natural stabilisers owing to the gradual growing demand for pursuing green‐label products. Based on this, the desalted duck egg white nanogels (DEWN) combined with κ‐carrageenan (CAR) (CAR/DEWN) were used as stabilisers to prepare environment‐friendly Pickering emulsions. The DEWN and CAR/DEWN as well as the particles‐stabilised emulsions were all characterised. Compared with the DEWN‐ and CAR‐stabilised emulsions, Pickering emulsions based on CAR/DEWN were investigated to illustrate the long‐term stability according to the results of visual appearance, static multiple light scattering and centrifugation experiments. In addition, CAR/DEWN could prepare stable high internal phase emulsions, which may give a new perspective for nutraceutical or drug encapsulation and delivery. Adding CAR to the DEWN not only increased the apparent viscosity of the emulsions to 122.2% but also enhanced the thixotropic recovery rate to 87.7%. In general, CAR/DEWN as stabilisers significantly promoted the Pickering emulsions' properties, and provided a possibility for the application of Pickering emulsion in foods.

Published: October 2021

AbstractIntroductionThe differential diagnosis of anemia is an important issue for hematology laboratories. We aimed at investigating the performance of a powerful computer‐based model to aid diagnosis.Materials and methodsOur work presents a new feature selection‐based automated disease diagnosis model. To create a testbed, a new corpus is collected retrospectively. Our data sets contain beta thalassemia trait, iron deficiency anemia, and healthy groups. Our presented automated ailment classification model consists iterative chi2 (IChi2) feature selection and classification phases. The used data set includes 25 features, and IChi2 selects the 20 most valuable of them. These are forwarded to 24 traditional classifiers.ResultsIn this work, two data sets have been used to test our proposal. In the classification phase of this model, 24 shallow classifiers have been used and the best accurate classifiers are Medium Gaussian Support Vector Machine (MGSVM) and Coarse Tree (CT) for the first and second data sets, respectively. These classifiers have been attained 97.48% and 99.73% classification accuracies using the first and second data sets, consecutively. These results are calculated using 10‐fold cross‐validation. Moreover, hold‐out validation has been used in this work, and the results are given in the experiments.ConclusionOur results denoted the success of IChi2‐based classification model for diagnosis on the laboratory data set. We have found a new and robust model to differentiate iron deficiency anemia and beta thalassemia trait. This model may be beneficial for rational laboratory use.

Published: October 2021

RésuméL'automatisation est réputée nuire à l'emploi, notamment si les tâches sont répétitives et facilement codifiables. Les auteurs analysent la situation dans le secteur de l'habillement, une industrie créatrice d'emplois, qui permet d'accéder aux marchés mondiaux et joue à ce titre un rôle clé pour le développement. Ils montrent que l'automatisation reste limitée dans la branche, alors même que l'essentiel des emplois y sont routiniers. À partir d'entretiens conduits auprès de cadres de grandes enseignes du secteur, ils apportent un éclairage inédit sur l'usage actuel et prévisible des technologies, les freins à leur diffusion et leurs effets potentiels sur la géographie de la production et de l'emploi.
Más allá de la «Industria 4.0»: Las redes de fábricas B2B como alternativa para la transformación digital de la producción y el trabajo
Authors: BUTOLLO Florian , SCHNEIDEMESSER Lea 
Published: October 2021

ResumenPartiendo de los postulados de Piore y Sabel (1984) sobre especialización flexible, se critica la unilateralidad del discurso de la Industria 4.0 contrastando este modelo de digitalización de las manufacturas con hallazgos empíricos sobre las redes de fábricas B2B mediadas por plataformas, cuya flexibilidad se deriva de la interconexión digital de multitud de pequeños fabricantes, más que de una sofisticada tecnología de producción. Los efectos que tendrán sobre el trabajo no quedan claros; frente al potencial de su paradigma de fabricación a pequeña escala similar al de la artesanía para mejorar el trabajo, existe el riesgo de competencia a la baja en las industrias sensibles a los precios.
Multimethodology for diagnosis and intervention in a prosthetics and orthotics factory in Brazil
Authors: Jahara Rafael da Costa , Lins Marcos Pereira Estellita 
Published: October 2021

AbstractThis paper develops an approach that articulates methods characterized as soft and hard Operational Research. This approach is known in the literature as Multimethodology, Hybrid Modeling, or Mixing Methods. As a Multi‐Paradigm Hybrid Study, the present research provides an interface between the qualitative and quantitative modeling of the problem addressed. In this way, it facilitates the engagement of managers with analysts in the search for solutions to problems. The applied objective is to improve the performance of production processes at a prosthetics and orthotics factory located in Rio de Janeiro, Brazil. It applies a multimethodology to support evaluation and intervention using knowledge mapping and a discrete‐event simulation model. Lessons learned from integrated workshops enabled the devising of an alternative improvement scenario for orthotics manufacturing. Theoretical results are validated through effective intervention, providing an increase in production capacity and reduction of the manufacturing lead time. This was made possible through the understanding and engagement of stakeholders during the modeling process.

AbstractAimsExplore the evidence from randomized controlled trials for the effect of self‐management interventions on quality of life, self‐management skills and self‐efficacy, and to explore which intervention characteristics are associated with effectiveness.DesignSystematic review.Data sourcesA search of the literature was conducted in these databases: MEDLINE (OVID), EMBASE (OVID) and PsychINFO (OVID) from January 2000 to February 2020.Review methodsStudies were included if participants had a bowel stoma, were over the age of 18 and the design was a randomized controlled trial of a self‐management programme. The outcome measures for this review were quality of life, self‐management skills and self‐efficacy. The Behaviour Change Technique Taxonomy was used to code interventions for underlying components and alongside other intervention characteristics, associations with improvements in outcomes were explored.ResultsThe search identified 3141 articles, 16 of which were eligible. A meta‐analysis of self‐efficacy scores from five studies (N = 536) found an improvement in those that received the self‐management intervention at follow‐up with a 12‐point mean difference compared with the usual care group. Effects on quality of life and self‐management skills were mixed, and meta‐analyses of these data were not possible. Across 13 studies an average of 10 behaviour change techniques were used with, credible source (e.g. nurse, doctor, therapist) (n = 13), instruction on how to perform the behaviour (n = 13), demonstration of the behaviour (n = 12) used most often. The behaviour change technique of self‐monitoring was associated with an improvement in quality of life. The involvement of a nurse was associated with higher self‐efficacy and self‐management skills.ConclusionThis review suggests that self‐management interventions can increase peoples’ self‐efficacy for managing their stoma.ImpactA standardized approach to the reporting of interventions and the measures used is needed in future studies to better understand the effect on quality of life and self‐management skills.
“It's not easy to change the mentality”: Challenges to sex education delivery for persons with intellectual disability
Authors: Azzopardi‐Lane Claire 
Published: October 2021

AbstractBackgroundSex education for people with intellectual disability is in its infancy in countries where their sexual expression is still considered a taboo. This study aimed at exploring the experiences of professionals involved in providing sex education to people with intellectual disability across a number of services in a Maltese context.MethodQualitative research was conducted using interviews to explore professionals' experiences of sex education provision.ResultsAmid a persistent culture of sexual suppression, desexualisation, infantalization and control remain barriers to sex education delivery. Findings underline the need for services to have clear policies that aid professionals in delivering sex education, while mitigating conflicts encountered. Recommendations highlight sex positive environments and services, with a pro‐active approach to sex education.ConclusionIn spite of internationally binding legislation and local policies, further changes need to be made on the ground to provide persons with intellectual disability with effective access to sex education.

AbstractWe examined the mechanism by which lithium chloride (LiCl) attenuates the impaired learning capability and memory function of dual‐transgenic APP/PS1 mice. Six‐ or 12‐month‐old APP/PS1 and wild‐type (WT) mice were randomized into four groups, namely WT, WT+Li (100 mg LiCl/kg body weight, gavage once daily), APP/PS1 and APP/PS1+Li. Primary rat hippocampal neurons were exposed to β‐amyloid peptide oligomers (AβOs), LiCl and/or XAV939 (inhibitor of Wnt/β‐catenin) or transfected with small interfering RNA against the β‐catenin gene. In the cerebral zone of APP/PS1 mice, the level of Aβ was increased and those of α7 nicotinic acetylcholine receptors (nAChR), phosphor‐GSK3β (ser9), β‐catenin and cyclin D1 (protein and/or mRNA levels) reduced. Two‐month treatment with LiCl at ages of 4 or 10 months weakened all of these effects. Similar expression variations were observed for these proteins in primary neurons exposed to AβOs, and these effects were attenuated by LiCl and aggravated by XAV939. Inhibition of β‐catenin expression lowered the level of α7 nAChR protein in these cells. LiCl attenuates the impaired learning capability and memory function of APP/PS1 mice via a mechanism that might involve elevation of the level of α7 nAChR as a result of altered Wnt/β‐catenin signalling.

AbstractThe interplay between mesenchymal stem/stromal cells (MSCs) and preservation conditions is critical to maintain the viability and functionality of these cells before administration. We observed that Ringer lactate (RL) maintained high viability of bone marrow–derived MSCs for up to 72 h at room temperature (18°C–22°C), whereas adipose‐derived and umbilical cord‐derived MSCs showed the highest viability for 72 h at a cold temperature (4°C–8°C). These cells maintained their adherence ability with an improved recovery rate and metabolic profiles (glycolysis and mitochondrial respiration) similar to those of freshly harvested cells. Growth factor and cytokine analyses revealed that the preserved cells released substantial amounts of leukaemia inhibitory factors (LIFs), hepatocyte growth factor (HGF) and vascular endothelial growth factor‐A (VEGF‐A), as well as multiple cytokines (eg IL‐4, IL‐6, IL‐8, MPC‐1 and TNF‐α). Our data provide the simplest clinically relevant preservation conditions that maintain the viability, stemness and functionality of MSCs from perinatal and adult tissue sources.
