Equity across the cancer care continuum for culturally and linguistically diverse migrants living in Australia: a scoping review
Authors: Scanlon Brighid , Brough Mark , Wyld David , Durham Jo
Published: July 2021

International evidence suggests migrants experience inequitable access, outcomes and treatment quality across the cancer care continuum. There is currently limited research assessing equity across the cancer care continuum for culturally and linguistically diverse migrants living in Australia. A detailed protocol and search strategy were developed and used to identify all relevant literature, utilising the Joanna Briggs Institute Reviewer’s Manual. Systematic searching was conducted via multiple databases and identified studies were screened against pre-identified inclusion and exclusion criteria. 71 studies met the inclusion criteria for analysis. Most studies examined cancer detection via screening. Very few studies examined cancer prevention, diagnosis, treatment or palliative care. Most studies focused on patient-sided barriers to care and there was a paucity of information regarding institutional barriers to health. Cancer-related outcomes were seldom examined, and most studies were qualitative or behavioral analysis. Results highlighted significant communication issues spanning the cancer care continuum and a context of inadequate support for both patients and clinicians. There is a demonstrable need to examine equity in access and outcomes for culturally and linguistically diverse cancer populations. This requires the identification of cancer-related disparities and an examination of institutional barriers to care. Through addressing this dearth of information, future research and health policy can support the operationalisation of health equity.

Published: July 2021

Background

Symptoms of attention deficit hyperactivity disorder (ADHD) are commonly comorbid with depression This study aimed to examine the relationship between ADHD symptoms and depression through perceived family support and to explore whether the magnitude of the relationship depended on the type of family climate of medical students.

Methods

This cross-sectional study was conducted among 124 first year medical students in Thailand. Participants completed questionnaires on ADHD symptoms, depression, perceived family support, and 9 types of family climate. The questionnaires included the Adult ADHD Self-Report Scale Screener, Patient Health Questionnaire-9, and revised Thai Multidimensional Scale of Perceived Social Support. Mediational analysis was adopted to examine the mediating role of perceived family support in the relationship between ADHD symptoms and depression, while moderation analysis was applied to examine the extent of the relationship depending on family climate.

Results

The relationship between ADHD symptoms and depression was moderate. Perceived family support partially mediated this relationship after controlling for age and sex. Among the types of family climate, only helpful family climate was a significant moderator of perceived family support and depression. The moderated mediation model increased the variance in depression from 17% by the mediation model to 21%. However, follow-up conditional mediational analysis showed that the indirect effect of ADHD symptoms on depression via perceived family support was not significant and that this effect did not vary linearly as a function of helpful family climate.

Conclusion

The findings of the study revealed that poor family support might be one risk of developing depression in the context of ADHD symptoms. Further study on providing intervention concerning family support among those with ADHD symptoms should be warranted. In addition, a study on helpful family climate in a larger sample size, in other populations, and in a longitudinal fashion for a more robust conclusion is encouraged.

Published: July 2021

Background

Teaching engineering at a high school level has been a subject of substantial concern during recent curriculum reforms. Many countries are increasingly including engineering-focused subjects in their technology curriculum guidelines. However, technology teachers face challenges regarding the optimal implementation of an engineering-focused curriculum. It is essential to understand technology teachers’ perceptions of and behavior in classroom practices when teaching an engineering-focused curriculum. To explore the factors influencing the effective implementation of the curriculum, this study aimed to explore the association between technology teachers’ perceptions regarding curriculum guidelines (i.e., perceived ease of use, perceived usefulness, and beliefs) and their behavioral intentions. In addition, this study explored how these perceptions change for teachers who participated in a professional development program (PDP) for teaching an engineering-focused curriculum compared with those who did not participate in the program (NoPDP).

Results

In this study, structural equation modeling was used to investigate factors potentially influencing teachers’ behavioral intentions, including subjective norms and perceived behavioral control. The results showed that technology teachers’ behavioral intentions were influenced by their perceptions of the curriculum's usefulness. Subjective norms and perceived behavioral control were also significant determinants of behavioral intentions. Moreover, the results differed between the two groups. Perceived usefulness had direct and indirect effects on the behavioral intentions of the PDP and NoPDP groups, respectively.

Conclusions

We constructed a model of technology teachers’ behavioral intentions to implement an engineering-focused curriculum and identified factors influencing technology teachers’ behavioral intentions to implement an engineering-focused curriculum. Our conclusions are as follows: (1) the model was adequate for determining the factors influencing technology teachers’ behavioral intentions; (2) in the PDP group, perceived usefulness, subjective norms, and perceived behavioral control were significantly associated with behavioral intentions; and (3) in the NoPDP group, perceived usefulness and perceived ease of use were associated with behavioral intentions and self-reported behavior only via the mediating factor of beliefs. The above influencing factors should be taken into account when planning professional development programs for pre- and in-service teachers, as these programs will have implications regarding the successful implementation of an engineering-focused curriculum.

Authors: Šimić Luka , Kopačin Vjekoslav , Mumlek Ivan , Butković Josip , Zubčić Vedran
Published: July 2021

With advancements in computer systems, computer graphics and medical imaging technologies, clinicians strive for a personalised approach to patient treatment. Therefore, the production of personalised surgical guides is becoming standard. While proprietary software solutions for mandibular reconstruction planning exist, they are often not available due to their high costs. There are multiple alternative methods available, which utilise open-source technologies and free software, but they use advanced three-dimensional (3D) computer-aided design (CAD) concepts. The goal of this article is to provide end-users (surgeons, radiologists, or radiology technicians) with a tool that offers an intuitive interface and a simple workflow. The tool provides only the necessary methods offering a high degree of automation and abstracting the underlying 3D CAD concepts. This is accomplished by providing an add-on (written in Python) for a free and open-source software package Blender.
Risk factors of laryngeal injuries in extubated critical pediatric patients
Authors: Algebaly HebatAllah Fadel , Mohsen Mona , Naguib Maggie Louis , Bazaraa Hafez , Hazem Noran , Aziz Miriam Magdy
Published: July 2021

Background

The larynx in children is unique compared to adults. This makes the larynx more prone to trauma during intubation. Under sedation and frequent repositioning of the tube are recorded as risk factors for laryngeal injury. We examined the larynx of 40 critically ill children in the first 24 h after extubation to estimate the frequency and analyze the risk factors for laryngeal trauma using the classification system for acute laryngeal injury (CALI).

Results

The post-extubation stridor patients had a higher frequency of diagnosis of inborn errors of metabolism, longer duration of ventilation, longer hospital stay, moderate to severe involvement of glottic and subglottic area, frequent intubation attempts, and more than 60 s to intubate Regression analysis of the risk factors of severity of the injury has shown that development of ventilator-associated pneumonia carried the highest risk (OR 32.111 95% CI 5.660 to 182.176), followed by time elapsed till intubation in seconds (OR 11.836, 95% CI 2.889 to 48.490), number of intubation attempts (OR 10.8, CI 2.433 to 47.847), and development of pneumothorax (OR 10.231, 95% CI 1.12 to 93.3).

Conclusion

The incidence of intubation-related laryngeal trauma in pediatric ICU is high and varies widely from mild, non-symptomatic to moderate, and severe and could be predicted by any of the following: prolonged days of ventilation, pneumothorax, multiple tube changes, or difficult intubation.
Building capacity for implementation—the KT Challenge
Authors: Black Agnes T. , Steinberg Marla , Chisholm Amanda E. , Coldwell Kristi , Hoens Alison M. , Koh Jiak Chin , LeBlanc Allana , Mackay Martha , Salmon Amy , Snow M. Elizabeth
Published: July 2021

Background

The KT Challenge program supports health care professionals to effectively implement evidence-based practices. Unlike other knowledge translation (KT) programs, this program is grounded in capacity building, focuses on health care professionals (HCPs), and uses a multi-component intervention. This study presents the evaluation of the KT Challenge program to assess the impact on uptake, KT capacity, and practice change.

Methods

The evaluation used a mixed-methods retrospective pre-post design involving surveys and review of documents such as teams’ final reports. Online surveys collecting both quantitative and qualitative data were deployed at four time points (after both workshops, 6 months into implementation, and at the end of the 2-year funded projects) to measure KT capacity (knowledge, skills, and confidence) and impact on practice change. Qualitative data was analyzed using a general inductive approach and quantitative data was analyzed using non-parametric statistics.

Results

Participants reported statistically significant increases in knowledge and confidence across both workshops, at the 6-month mark of their projects, and at the end of their projects. In addition, at the 6-month check-in, practitioners reported statistically significant improvements in their ability to implement practice changes. In the first cohort of the program, of the teams who were able to complete their projects, half were able to show demonstrable practice changes.

Conclusions

The KT Challenge was successful in improving the capacity of HCPs to implement evidence-based practice changes and has begun to show demonstrable improvements in a number of practice areas. The program is relevant to a variety of HCPs working in diverse practice settings and is relatively inexpensive to implement. Like all practice improvement programs in health care settings, a number of challenges emerged stemming from the high turnover of staff and the limited capacity of some practitioners to take on anything beyond direct patient care. Efforts to address these challenges have been added to subsequent cohorts of the program and ongoing evaluation will examine if they are successful. The KT Challenge program has continued to garner great interest among practitioners, even in the midst of dealing with the COVID-19 pandemic, and shows promise for organizations looking for better ways to mobilize knowledge to improve patient care and empower staff. This study contributes to the implementation science literature by providing a description and evaluation of a new model for embedding KT practice skills in health care settings.
Lapse-Based Insurance
Authors: Gottlieb Daniel , Smetters Kent
Published: July 2021

Most individual life insurance policies lapse, with lapsers cross-subsidizing non-lapsers. We show that policies and lapse patterns predicted by standard rational expectations models are the opposite of those observed empirically. We propose two behavioral models consistent with the evidence: (i) consumers forget to pay premiums and (ii) consumers understate future liquidity needs. We conduct two surveys with a large insurer. New buyers believe that their own lapse probabilities are small compared to the insurer’s actual experience. For recent lapsers, forgetfulness accounts for 37.8 percent of lapses while unexpected liquidity accounts for 15.4 percent. (JEL D91, G22, G52)
Imaging in non-cystic fibrosis bronchiectasis and current limitations
Authors: Ledda Roberta Eufrasia , Balbi Maurizio , Milone Francesca , Ciuni Andrea , Silva Mario , Sverzellati Nicola , Milanese Gianluca
Published: July 2021

Non-cystic fibrosis bronchiectasis represents a heterogenous spectrum of disorders characterised by an abnormal and permanent dilatation of the bronchial tree associated with respiratory symptoms. To date, diagnosis relies on computed tomography (CT) evidence of dilated airways. Nevertheless, definite radiological criteria and standardised CT protocols are still to be defined. Although largely used, current radiological scoring systems have shown substantial drawbacks, mostly failing to correlate morphological abnormalities with clinical and prognostic data. In limited cases, bronchiectasis morphology and distribution, along with associated CT features, enable radiologists to confidently suggest an underlying cause. Quantitative imaging analyses have shown a potential to overcome the limitations of the current radiological criteria, but their application is still limited to a research setting.

In the present review, we discuss the role of imaging and its current limitations in non-cystic fibrosis bronchiectasis. The potential of automatic quantitative approaches and artificial intelligence in such a context will be also mentioned.

Authors: Martocchia Antonio , Scarienzi Marta , Prunas Pietro , Bentivegna Enrico , Cacciafesta Mauro , Martelletti Paolo , Sesti Giorgio
Published: July 2021

Background: Behavioral and psychological symptoms of dementia (BPSD) and delirium are common in advanced phases of Alzheimer’s disease (AD).

Methods: Thirty-eight moderate-severe AD patients were enrolled (n=16 affected by type 2 diabetes). Each patient received a comprehensive geriatric assessment (CGA) (including evaluation of BPSD and frailty), and a complete metabolic evaluation (including the measurement of the glycated hemoglobin, HbA1c).

Results: Both the hyper- and hypo-glycemic extremes of the glycemic spectrum worsened BPSD, but delirium was more susceptible to hypoglycemic events. The severity of delirium was significantly related to cognitive function (r = -0.585, p<0.001) and frailty (r = +0.440, p<0.05).

Conclusions: The measurement of HbA1c was useful for evaluating the risk of delirium in relationship to glycemic control and nutritional status.

Published: July 2021

This dataset is an accumulation of data collected to test Rwandan physics students’ conceptual understanding of light phenomena and to assess instructional tools for active learning of optics. We collected and analysed data from 251 grade 11 (senior 5) students using our Light Phenomena Conceptual Assessment (LPCA) tool and from 136 grade 10 (senior 4) students using Geometric Optics Conceptual Understanding Test (GOCUT) in 2019. Before collecting data, we designed and validated LPCA and GOCUT, and tested their reliability. Data were collected before and after students learnt about the unit of light. Both day and boarding schools in rural and urban areas were included in our sampling. Data collected were test scores from students after performing a 30-item LPCA test or 25-item GOCUT test in 40 minutes. The data may be reused to extend  students' understanding of optics concepts through item analysis, analysis of school characteristics such as location and school type, or by analysing students' characteristics such as subject combinations.
Correlation between CD44+ cancer stem cell expression and histopathological types of nasopharyngeal carcinoma
Authors: Yusuf Muhtarum , Indra Indriyadevi , Juniati Sri Herawati , Afriani Dewi Yussy
Published: July 2021

Background: Nasopharyngeal carcinoma (NPC) recurrency rate is still high despite patients receiving complete treatment. The response to treatment may vary depending on the type of histopathology and Epstein-Barr virus, however the mechanism remains unclear. Recent studies have found that there is a relationship between response to treatment and the presence of cancer stem cells (CSCs). CD44+ cancer stem cells may cause cancer cells to be resistant to treatment. Therefore, this cross-sectional study aims to determine the correlation between CD44 + cancer stem cell expression and the histopathological types of NPC.

Method: Samples were obtained from NPC biopsies of type I, II, III patients (based on WHO histopathology criteria), who had not received prior treatment. CD44+ expression was examined using immunohistochemistry methods by staining CD44+ monoclonal antibodies. The degree of CD44+ cell membrane expression was based on the immunoreactive score scale or the Remmele index scale.

Results: Most histopathological types were WHO type III (21 patients, 50%), followed by type II (18 patients, 42.86%), and type I (3 patients, 7.14%). CD44 + expression on type I showed one patient had moderate positive and two patients had a high-positive expression. In type II, 10 were moderate positive and eight were high-positive. In type III, one patient was low-positive, 11 were moderate positive and nine patients were high-positive. Statistical analysis showed that the CD44+ expression difference between the three histopathology types were not statistically significant.

Conclusion: There were no correlations between CD44 + expression and histopathological type of NPC.

Published: July 2021

Degradation in the polymeric insulators is caused due to the environmental stresses. The main aim of this paper is to explore the improved aging characteristics of hybrid samples by adding nano/micro silica in High Temperature Vulcanized Silicone Rubber (HTV-SiR) under long term accelerated aging conditions for 9000 hours. As HTV-SiR is unable to sustain environmental stresses for a long time, thus a long term accelerated aging behavior is an important phenomenon to be considered for field application. The aging characteristics of nano/micro filled HTV-SiR are analyzed by using techniques such as Scanning Electron Microscopy (SEM), Leakage Current (LC), Fourier Transform Infrared Microscopy (FTIR), Hydrophobicity Classification (HC), and breakdown strength for the aging time of 9000 hours. FTIR and leakage currents are measured after every cycle. All the co-filled samples revealed escalated aging characteristics as compared to the neat sample except the SN8 sample (8% nano-silica+20% micro-silica) after 9000 hours of aging. The highest loading of 6% and 8% nano-silica with 20% micro-silica do not contribute to the improved performance when compared with the neat and hybrid samples. However, from the critical experimental analysis, it is deduced that SN2 sample (2% nano-silica+20% micro-silica) is highly resistant to the long term accelerated aging conditions. SN2 has no cracks, lower loss percentages in the important FTIR absorption peaks, higher breakdown strength and superior HC after aging as compared to the unfilled and hybrid samples.

Governance and structuring of public and urban space in Bilbao: analysis of global trends at the local level
Authors: Lekue Iago
Published: July 2021

The phenomenon of deindustrialization, as well as the vertiginous changes dependent on financial capital, produced new trends in the models of organization and production of western cities such as Bilbao. The socio-spatial organization and structuring of the ‘new city’ begins to be a topic of great importance. It is in this sense that the concepts of public and urban space take on greater theoretical relevance. The results obtained through the application of the theory in the case of Bilbao, follow global urban development tendencies. Spatial planning fulfils the strategic functions of a system that dominates urban processes at their convenience. There is a tendency to build aseptic spaces that are closer to the interests of capital than of citizens.
Performing the Female Alternative in Victorian Popular Drama: The “Girl of the Period” and the “Fast Girl”
Authors: Puchal Terol Victoria
Published: July 2021

During the nineteenth century, theatregoing became the favoured entertainment of both the lower and upper classes in London. As Davis (1994, 307) suggests, the plays were a “mirrored reflection” of society, and they had the ability to reflect important socio-political issues on stage, while also influencing people’s opinion about them. Thus, by turning to the popular stage of the mid-century we can better understand social issues like the Woman Question, or the tensions around imperial policies, among others. As such, this article scrutinises the ways in which Victorian popular drama influenced the period’s ideal of femininity by using stock characters inspired by real women’s movements. Two such cases are the “Girl of the Period” and the “Fast Girl”, protofeminists that would go on to influence the New Woman of the fin-de-siècle. We analyse two plays from the mid-century: the Adelphi’s Our Female American Cousin (1860), by Charles Gayler, and the Strand’s My New Place (1863), by Arthur Wood. As this article attests, popular plays like these would inadvertently bring into the mainstream the ongoing political fight for female rights through their use of transgressive female characters and promotion of scenarios where alternative feminine identities could be performed and imagined.
“Come, Dark-eyed Sleep”: Michael Field and the Performance of the Lyric as a Radical Fantasy
Authors: Cantillo Lucuara Mayron Estefan
Published: July 2021

This article seeks to illustrate how the Michael Fields articulate their Sapphic poetry in Long Ago (1889) not only in keeping with their own Shakespearean aspirations and with Robert Browning’s hybrid formula of dramatic lyrics, but also in connection with Jonathan Culler’s theory of the lyric as a performative genre. Much recent scholarship has broken ground in the rediscovery and reappraisal of the Fields’ literary stature, yet the general critical approach has been divisive in addressing their poetry and their verse dramas separately. Some critics have taken heed of how their lyrics in general exhibit an intrinsic dramatic temper, yet no systematic inquiry has discussed how this lyrical dramaticity is manifest in any particular instance. Thus, this article singles out Long Ago’s second poem for its powerful performative energy, offering a close reading of each line, and demonstrating that it amounts to a hybrid dramatic lyric, as well as a tragic and transgressive performance in which a new Sappho takes centre stage as a Dionysian apologist of radical erotic fantasies.
Disrupting Temporalities, Multiplying the Self: An Age-Studies Approach to Two Contemporary Plays
Authors: Casado-Gual Núria , Shevchenko-Hotsuliak Inesa
Published: July 2021

In our increasingly aged societies, old age continues to be equated with decline (Gullette 2004) and becomes the source of the most invisible yet persistent forms of discrimination, namely, ageism (Butler 1969). Even though theatre, like other artistic forms, has traditionally promoted a negative image of ageing (Mangan 2013), some contemporary plays have begun to favour more complex portrayals of old age. Nevertheless, when considered from a gender-based angle, these portrayals often acquire quite a problematic undertone: while roles for older female actors remain exceptional, many peripheral or, if centred, mainly problematic dramatizations of ageing femininity in the theatre arena fuel age prejudice against older women on and off stage. This article offers an age-focused analysis of two plays that counteract stereotypical images of female ageing through various dramaturgical strategies: Michel Tremblay’s Albertine in Five Times (1984) and Matt Hartley’s Here I Belong (2016). Through a comparative analysis of the Naturalistic and Non-Naturalistic devices employed in the two plays, and the examination of the meanings of age generated by the characterization of the two female protagonists, we hope to demonstrate that Tremblay’s and Hartley’s texts contribute to creating a truly anti-ageist theatre while at the same time enhancing the visibility of the older woman on the stage.
Performative Encounters: Memory Violence in Sleep Deprivation Chamber
Authors: Barba Guerrero Paula
Published: July 2021

In their biographical play Sleep Deprivation Chamber (1996), Adrienne Kennedy and her son Adam P. Kennedy retrace family memories to describe the aftermath of police brutality in 1990s America. They narrate the brutal beating of a middle-class, young Black man named Teddy and the events taking place later at trial. The playwrights make use of “memory violence” (Olick 2018) to elicit the spectators’ emotional response and construct a performative encounter in which the figures of perpetrator, survivor and bystander are questioned and redefined. Through this violence of remembering, they manage to insert unrecorded moments of abuse in our collective imaginary, moving from staged nightmares, distant courtrooms and individual sleep deprivation chambers into a figurative shared space where Black lives do matter.
Adaptation against Myth: Gary Owen’s Iphigenia in Splott and the Violence of Austerity
Authors: Gualberto Rebeca
Published: July 2021

This article explores, from the standpoint of socio-political myth-criticism, the processes of revision and adaptation carried out in Gary Owen’s 2015 play Iphigenia in Splott. The play, a dramatic monologue composed in the rhythms of slam poetry, rewrites the classical Greek myth of Iphigenia in order to denounce the profound injustice of the sacrifices demanded by austerity policies in Europe—and more specifically, in Britain—in the recession following the financial crash of 2008. Reassessing contemporary social, economic and political issues that have resulted in the marginalisation and dehumanisation of the British working class, this study probes the dramatic and mythical artefacts in Owen’s harrowing monologue by looking back to Euripides’s Iphigenia in Aulis, the classical play which inspires the title of Owen’s piece and which serves as the mythical and literary background for the story of Effie. The aim is to demonstrate how Owen’s innovative adaptation of the sacrifice of Iphigenia, slurred out in verse, resentful and agonising, speaks out a desperate plea against myth, that is, against a dominant social ethos that legitimises its own violence against the most vulnerable—those who, as in the classical myth, suffer the losses that keep our boats afloat.

Trata-se de um extrato da pesquisa de Mestrado em Educação, realizada na Universidade Federal de Mato Grosso, campus Rondonópolis, que investigou a história e as práticas de leitura realizadas no interior da BPEMT. Nesta oportunidade, apresentaremos a história de sua fundação, bem como, a sua estrutura física e organização. Caracteriza-se como pesquisa histórica, na perspectiva da história cultural e utilizou como instrumento para coleta de dados o registro digital (fotos), e a organização e transcrição do conteúdo das fontes. Estas, foram: relatórios e regulamentos emitidos pelos diretores da biblioteca, mensagens do governador à Assembleia Legislativa e artigos de jornais. Apoiou-se em autores como: Le Goff (1993), Chartier (2001), Darnton (2010a 2010b), Deaecto (2011), Abreu (1999), entre outros. Os resultados evidenciam que: a biblioteca foi criada e mantida em Cuiabá, até a década de 1950, como auxiliar da instrução pública; possuía um acervo diversificado constituído em grande parte por doações; houve presença de consulentes, ou seja, possíveis leitores, de forma efetiva até a década de 50, período em que a biblioteca ficou praticamente desativada. Considera-se que a BPEMT foi um espaço que colaborou com as práticas de leitura da comunidade de leitores de Cuiabá, principalmente estudantes e alguns profissionais da elite cuiabana, como advogados e engenheiros. As informações sistematizadas no estudo poderão contribuir para a construção da história cultural de Mato Grosso.

Published: July 2021

O artigo busca caracterizar a Biblioteca Pública (BO) como equipamento sociocultural relevante na condução de uma cultura civilizatória e cidadã, observando as tensões sociais e as demandas dos mais diversos grupos com relação ao acesso à bens, serviços e produtos culturais, situando tal instituição como relevante para o desenvolvimento e de forte potencial para impactos sociais profundos. Traz reflexões acerca dos desafios enfrentados historicamente, os caminhos para configuração e execução de políticas públicas, além dos problemas decorrentes da flutuação e descontinuidade de políticas, programas e projetos que tangenciam ou determinam as formas de atuação da BP. O papel e o poder dessas instituições são reafirma quando se percebe que na maior parte dos municípios brasileiros, ela é o único equipamento sociocultural em funcionamento e com livre acesso para a população local, desempenhando o papel de centro de cultura e convivência.
MECHANICAL BEHAVIOR OF HORIZONTAL SWIVEL SYSTEM WITH UHPC SPHERICAL HINGE UNDER SEISMIC ACTION
Authors: Wang Jiawei , Cao Bing , Huang Bo , Du Yihan
Published: July 2021

In the process of rotation, the total weight of the bridge structure is jointly supported by the spherical hinge and the supporting structure, and its lateral stability is poor. It is easy to lose stability under the action of dynamic loads such as seismic action effect. The present paper takes a 10,000-ton continuous rigid frame swivel bridge as the re-search object, analyzes the dynamic response of the seismic action to the horizontal swivel system, and establishes several structure simulation models. Eighteen seismic waves in three directions that meet the calculation requirements are screened for time history analysis and compared with the response spectrum method. Finally, an optimization algorithm for the seismic response of the bridge under horizontal swivel system is proposed based on the mode superposition method. The UHPC spherical hinge bears all the vertical forces and 20% of the bending moment caused by the seismic action, the support structure bearing the remaining 80% of the bending moment. The optimization algorithm proposed in this paper features high accuracy.

Authors: Christopher
Published: July 2021

Understanding of the internal arrangement of the constituents of structural concrete, at the microscopic level, and its strength behavior, as well as its ability to result in durable concrete, are necessary in order to enhance its innovative and sustainable application. This paper presents the results of investigation conducted to ascertain the strength characteristics, microstructure configuration and durability traits of concrete with its ordinary Portland cement (OPC) fraction replaced partially with empty palm oil fruit brunch ash (EPO-FBA). The compressive strength properties were assessed with 150 x 150 x 150 cube specimens while 100 x 100 x 100 cube specimens were used to assess the durability properties. An insight into the morphology and the microstructure of samples with EPO-FBA was obtained through Scanning Electron Microscopy (SEM). The results showed that EPO-FBA is a good supplementary cementing material up to 10% replacement level, however, the samples with EPO-FBA showed a significantly improved compressive strengths development and good durability characteristics at latter ages, at the replacement level beyond 10%.

Authors: Zhang Kexin
Published: July 2021

In order to study the properties of polyurethane cement composite (PUC) material, this paper has carried out the tests of compressive resistance, flexural resistance, axial tension, bonding and acid and alkali corrosion resistance of the material. The average compressive strength of the material is 59.3 MPa, the average flexural strength is 41.5 MPa, and the average axial tensile strength is 31.0 MPa. The bonding strength between the material and concrete in axial tension is 3.56 MPa, and that between the material and concrete in bending is 3.16 MPa. The failure interface of the two bond tests is not on the bond surface, indicating that the polyurethane cement composite (PUC) material has good bonding property. The chemical corrosion resistance test of polyurethane cement material showed no visible change on the surface of the material, indicating good chemical corrosion resistance.
ANALYSIS OF DYNAMIC AND STATIC CHARACTERISTICS OF PIPELINE SUSPENSION BRIDGE WITH WIND CABLES
Authors: Liu Long , Li Wenqi
Published: July 2021

In this paper, a suspension bridge carrying oil pipelines is taken as the research object. A spatial finite element analysis model of the bridge is established for the bridge by using MIDAS/CIVIL finite element analysis software, and the structural analysis of static and dynamic characteristics is carried out. The analysis of dynamic characteristics shows that the wind cable can greatly improve the natural vibration characteristics of the suspension bridge. The analysis of static characteristics shows that the internal forces of the suspender are evenly distributed and the vertical displacement of the main girder of the steel truss is distributed in a parabola, besides, the strength of each main component can meet the safety needs.

In particular, we explicitly characterize the measure of Ω for which the maximum principles corresponding to this problem hold in Ω. For this, we derived an explicit lower estimate of principal eigenvalues in terms of the measure of Ω. Aleksandrov–Bakelman–Pucci (ABP) type estimates for the above systems are also proved. We also show the existence of a viscosity solution for a nonlinear perturbation of the nonhomogeneous counterpart of the above problem with polynomial and exponential growths. As an application of the maximum principles, we measure explicitly how small

The Effect of Halide Counter Ions and Methanol on the Foaming Behavior of Cationic Surfactants and a Mechanism Study
Authors: Bai Yun , Zhang Jie , Dong Sanbao , Zhu Shidong , Wang Manxue , Wu Ya , Pu Chunsheng , Chen Gang
Published: July 2021

In this work, four quaternary ammonium cationic surfactants including cetyltrimethyl ammonium fluoride (CTAF), cetyltrimethyl ammonium chloride (CTAC), cetyltrimethyl ammonium bromide (CTAB) and cetyltrimethyl ammonium iodide (CTAI) were investigated to study the effect of halide anions on the surface activity and foaming performance. The result showed that CTAF had superior surface activity, which could reduce the surface tension of water to 33.15 mN/m at a low CMC (critical micelle formation concentration) of 1.65 mmol/L. Based on the calculation of Amin (the minimum occupied area per surfactant molecule), we assumed that this higher surface activity was related to the small ionic radius of the fluorine ion (F–). The foamability and foam stability of CTAF has great advantages over other surfactants studied. On this basis, the factors affecting the formation and stabilization of the CTAF foam were investigated. The results showed that foam formation benefited from high temperatures and low methanol concentration, while high salinity was beneficial for foam stability. When CTAF at a concentration of 0.2% was used as a foaming agent, foaming was excellent at a methanol concentration of 10%, a salinity of 22 ⨯ 104 mg/L, and a temperature of 90°C. With this study, uncertainties that existed in the literature regarding the effect of anion on surface activity and foam performance were explained and the effect of temperature, methanol and salinity on foam generation and stabilization was understood.

Published: July 2021

In this study, the synergistic effect of silica nanoparticle and biosurfactants on oil storage tank clean up was investigated. Rhamnolipid, saponin and silica nanoparticles were used to recover oil from refinery oily sludge in laboratory experiments. From our results, the optimum HLB value for the extraction process was about 10.5 for the mixture of 62.5% of rhamnolipid and 37.5% of saponin. Our results also showed that the simultaneous use of the biosurfactants and nanoparticles results in a synergistic effect that significantly enhances the process efficiency. Maximum yield of oil residual was obtained about 4% at the optimum condition (HLB value of 10.5 for mixture of the biosurfactants and 3 g/l of silica nanoparticles). The results of present study showed that this method has the potential for industrial applications and may be used in oil recovery from oily sludge.
