Microplastic removal via physical and chemical methods
Authors: L. Feo  , R. Pullar  , A. Zaoui
Published: April 2023

A growing number of synthetic plastics derived from fossil fuels are produced, and improper plastic waste management has caused a lot of pollution problems. There are many microplastics in the environment, and they disintegrate slowly in soil and water. The properties of microplastics include long residence times, high stability, high fragmentation potential, and the ability to adsorb other contaminants. Invertebrates and planktonic organisms are easily able to accumulate microplastics in aquatic species. Therefore, microplastics (MPs) must be removed from the water and other media. This paper aims to review the occurrence, raw polymers and additives, and remediation methods for removing microplastics from the environment. Several methods are available for removing contaminants, including sorption, filtration, and chemical treatments. Various removal methods are discussed along with their methods, efficiency, and advantages.
Investigation of structural and optical properties of In-doped AlSb nanostructures
Authors: S. Radiman  , M. Rusop
Published: April 2023

The first-principles calculations are made to study the structural electronic and optical properties of indium-doped aluminum antimonide. The most appropriate method of density functional theory (DFT) naming Full Potential Linearized Augmented Plane Wave (FP-LAPW) is used. The structural properties like Lattice constant (a), pressure derivative, and bulk modulus (B) were examined by Local density approximation (LDA) along with generalized gradient approximation (GGA). Generalized gradient approximation along with TB-mBJ is used to determine electronic parameters like band structure along and density of states. According to the computed results the binary compound AlSb is optically inactive and exhibits an indirect (Γ-L) band gap. By increasing the concentration of indium with different percentages, the indirect band gap shifted to the direct (Γ – Γ) band gap which shows the material is optically active. The optical properties of the material including dielectric (Real and imaginary parts) constant, reflectivity, refractive index, energy loss, absorption coefficient, and optical conductivity have changed significantly. Electronic and optical properties are modified by (TB-mBJ) approach. The results obtained are examined with experimental data and utilized as a starting point to propose that the material is the superlative choice for the manufacturing of p-n junctions, photo-detectors, laser, photo-diodes, transistors and solar spectrum absorptions in the visible, infrared and ultraviolet energy ranges.

Can we administer Acetazolamide in patients with heart failure? A systematic review
Authors: Santos Luna Maria Eduarda
Published: April 2023

Introduction: Heart failure (HF) is a clinical syndrome characterized by a variety of symptoms and signs due to structural and/or functional abnormalities of the heart leading to decreased heart rate, cardiac output and/or increased intracardiac pressures. Studies suggest that acetazolamide could improve the efficacy of ASA diuretics, which could lead to improved natriuresis and diuresis.
Aims: To evaluate the effectiveness of acetazolamide in improving congestion symptoms in patients with Heart Failure.
Methods: A systematic review will be carried out, following the PRISMA methodology, which will include a search in Pubmed, Scopus, Web of Science databases without time restriction.
Results: 5 studies were included, of which 4 were clinical trials.
Conclusions: After comprehensive and detailed analysis of the included studies, we found limited evidence suggesting that the use of acetazolamide may be effective in the treatment of heart failure, especially as additional or complementary therapy to other treatments. However, it is important to keep in mind that the results of the pilot studies are limited and that more research is required to fully evaluate the efficacy and safety of acetazolamide in the treatment of heart failure. The use of acetazolamide in patients with heart failure may be controversial and requires careful evaluation of clinical risks and benefits before it is considered as a treatment.
Towards an Understanding of Outreach and Identity: Professional Opera Singers’ Perspectives of Definitions, Value, and Status of Outreach
Authors: Leary Jessica L. , Drury Rachel
Published: April 2023

The growth of outreach work in classical music organisations over the last few decades has cemented its place as a fundamental part of such organisations’ output. In doing so, it has also created a different mode of professional work for artists. However, tensions exist within the terminology that is used to describe outreach work, and in the terminology used to differentiate outreach from what is seen as the main artistic output (often performance). Academic discussion on outreach programmes has often been framed in terms of numbers, demographics, and experiences in relation to the audience. By contrast, comparatively little research exists into the experiences of, and impact for, the artists who engage in outreach work as part of their professional careers, and even less in relation to the singer. This small-scale qualitative study explored the lived experience of professional singers engaged in opera outreach work in relation to language (terminology) and perceptions of identity and status. Its aims are to gain a deeper understanding of the lived experiences of professional opera singers within this specific professional world and offer insight around the tensions in terminology in relation to their identity (professional or subjective) and status. Findings suggest there is a lack of clarity around the definition of what outreach work is, both by those inside and outside the industry. Furthermore, this lack of clarity impacts the identity and status of those singers working in opera outreach.
Understanding the Vocal Skill Set for Contemporary Christian Singers: Insights from Elite Singers
Authors: Neto Leon , Meyer David
Published: April 2023

The American Academy of Teachers of Singing (AATS), advocates that CCM singers should be taught with dedicated pedagogical approaches for each style. Recent studies, however, suggest that most contemporary Christian singers (CCS) do not receive style-appropriate vocal training. It is possible that voice teachers are not fully aware of the skill set necessary for a CCS to be successful. In this context, elite CCSs, as models of excellence, may be able to help the voice community bridge this gap and identify the ideal skill set and the best pedagogical approach for the commercial success of CCSs. For this study, we interviewed three top selling, elite CCSs with extensive experience and recognised as highly representative of their style, aiming to understand the ideal vocal skill set of commercially successful CCSs. According to the participants, ideal CCS voices should use a pop sound and not sound too classical, should sing easily, comfortably, and with freedom. The singing should be not distracting and use good diction in order to be able to communicate the message clearly. Among the most relevant findings is the suggestion that CCSs have a heavy and demanding vocal load and are at risk for vocal injury. This finding is consistent to previous studies that suggest similar issues. We hope that our findings will help the development of more appropriate private studio strategies for CCSs. Future research for this population of singers may include analysis of worship applied voice curricula.
Reclaiming Singing as Art: The Trouble with Mechanics
Authors: Cole Amanda
Published: April 2023

The teaching of singing is increasingly influenced by research in the fields of health science and acoustics to the extent that teachers could be excused for thinking that they need a science or other technical degree in order to teach singing responsibly. While it is a step forward to increase the accuracy of our teaching language and the precision of the mechanical aspect of instruction, the author cautions against and draws attention to the growing risks of falling into the trap of a single-minded focus on mechanics in the voice studio. The author considers the increasing reliance on mechanical models for voice teaching, offering viewpoints from philosophy and poetry in a reminder to maintain balance in the modern voice studio. KEYWORDS: Classical and contemporary voice pedagogy, Voice science, Singing and psychology, Singing technique, medicalization, singing and performance, whole versus parts, art versus science, art of singing, mechanics, mechanistic teaching, the humanities, John Dewey.
From Participatory to Online: Exploring Contexts of Group Singing and the Role of the Singer
Authors: Hughes Diane
Published: April 2023

This article discusses the contexts of pre- and COVID-19 impacted group singing. It begins by outlining a purposely composed work, Wordsong, that sought to create organisational identity and foster community through in-person participatory and presentational singing. The subsequent online group singing strategies that are analysed and discussed, also sought to construct new musical identities and, for many, to create or sustain communities. Described as providing a ‘lifeline’ during the COVID-19 pandemic, the context of group singing online, particularly in relation to the multitracking of a group performance, ultimately changes the role of the singer within the group aesthetic. Indeed, like most recordings, the overall aesthetic is often engineered by someone other than the singer or singers. This creates several considerations when analysing the participatory ethos of group singing online. Until latency issues are resolved and appropriate technologies are developed to enable the real-time participatory or presentational singing afforded by works such as Wordsong, then group singing online is restricted in its traditional group singing capability. Instead, it is the singer’s perception of their individual sound that becomes a focus. This is particularly evident in relation to vocal ensemble strategies that were utilised in response to the COVID-19 pandemic. The article concludes with a model of the transformation from participatory singer to online audience member, that delineates the place or role of the singer within this transformation.

Authors: Angraini Lilis Marina , Alzaber  , Debby Permata Sari  , Ilham Muhammad
Published: April 2023

This research is motivated by the importance of mathematical critical thinking skills for students, as well as the rapid development of information technology in the digital era. This study specifically aims to improve students' mathematical critical thinking skills through the application of Augmented Reality (AR)-based learning media with 3D unity that can be used in online learning and offline learning based on Initial Mathematical Ability (IMA). Augmented Reality is a technology that combines three-dimensional virtual objects into a real environment and then projects these virtual objects in real-time. While the initial mathematical ability is one of the factors that influence the learning of mathematics, the higher the initial mathematical ability of a student, the better the level of the student's mathematical critical thinking ability. This research is quantitative research (quasi-experimental), while the research subjects are students at one of Pekanbaru's state junior high schools class VII for the academic year 2022/2023, as many as 30 students who are randomly selected by the class. This research was conducted on the material of flat shapes, especially triangles and quadrilaterals. The data collection method used was a mathematical critical thinking ability test. The test result data was processed by statistical tests, including a normality test, homogeneity test and two-way ANOVA test. The results showed that the improvement of mathematical critical thinking skills of students who received learning using augmented reality media with Unity 3D was better than the improvement of mathematical critical thinking skills of students who received conventional learning based on students' initial mathematical abilities.

Objectives

To estimate the prevalence in Australia of each type of child maltreatment; to identify gender‐ and age group‐related differences in prevalence.

Design, setting

Cross‐sectional national survey; mobile telephone interviews using random digit dialling (computer‐generated), Australia, 9 April – 11 October 2021. Retrospective self‐report data using validated questionnaire (Juvenile Victimisation Questionnaire‐R2 Adapted Version (Australian Child Maltreatment Study).

Participants

People aged 16 years or more. The target sample size was 8500 respondents: 3500 people aged 16–24 years and 1000 respondents each from five further age groups (25–34, 35–44, 45–54, 55–64, 65 years or more).

Main outcome measures

Proportions of respondents reporting physical abuse, sexual abuse, emotional abuse, neglect, and exposure to domestic violence to age 18 years, assessed with the Juvenile Victimization Questionnaire‐R2 Adapted Version (Australian Child Maltreatment Study), overall and by gender and age group, and weighted to reflect characteristics of the Australian population aged 16 years or more in 2016.

Results

Complete survey data were available for 8503 eligible participants (14% response rate). Physical abuse was reported by 32.0% of respondents (95% confidence interval [CI], 30.7–33.3%), sexual abuse by 28.5% (95% CI, 27.3–29.8%), emotional abuse by 30.9% (95% CI, 29.7–32.2%), neglect by 8.9% (95% CI, 8.1–9.7%), and exposure to domestic violence by 39.6% (95% CI, 38.3–40.9%). The proportions of respondents who reported sexual abuse, emotional abuse, or neglect were each statistically significantly larger for women than men. The reported prevalence of physical abuse by respondents aged 16–24 years was lower than for those aged 25–34 years, and that of sexual abuse was lower than for those aged 35–44 years, suggesting recent declines in the prevalence of these maltreatment types.

Conclusions

Child maltreatment is common in Australia, and larger proportions of women than men report having experienced sexual abuse, emotional abuse, and neglect during childhood. As physical and sexual abuse may have declined recently, public health policy and practice may have positive effects, justifying continued monitoring and prevention activities.

Objectives

To examine associations between child maltreatment and health service use, both overall, by type and by the number of types of maltreatment reported.

Design, setting

Cross‐sectional, retrospective survey using the Juvenile Victimization Questionnaire‐R2: Adapted Version (Australian Child Maltreatment Study); computer‐assisted mobile telephone interviews using random digit dialling, Australia, 9 April – 11 October 2021.

Participants

Australians aged 16 years or more. The target sample size was 8500 respondents: 3500 people aged 16–24 years and 1000 respondents each from the five age groups (25–34, 35–44, 45–54, 55–64, 65 years or more).

Main outcome measures

Self‐reported health service use during the past twelve months: hospital admissions, length of stay, and reasons for admission; and numbers of consultations with health care professionals, overall and by type. Associations between maltreatment and health service use are reported as odds ratios adjusted for age group, gender, socio‐economic status, financial hardship (childhood and current), and geographic remoteness.

Results

A total of 8503 participants completed the survey. Respondents who had experienced child maltreatment were significantly more likely than those who had not to report a hospital admission during the preceding twelve months (adjusted odds ratio [aOR], 1.39; 95% confidence interval [CI], 1.16–1.66), particularly admission with a mental disorder (aOR, 2.4; 95% CI, 1.03–5.6). The likelihood of six or more visits to general practitioners (aOR, 2.37; 95% CI, 1.87–3.02) or of a consultation with a mental health nurse (aOR, 2.67; 95% CI, 1.75–4.06), psychologist (aOR, 2.40; 95% CI, 2.00–2.88), or psychiatrist (aOR, 3.02; 95% CI, 2.25–4.04) were each higher for people who reported maltreatment during childhood. People who reported three or more maltreatment types were generally most likely to report greater health service use.

Conclusions

Child maltreatment has a major impact on health service use. Early, targeted interventions are vital, not only for supporting children directly, but also for their longer term wellbeing and reducing their health system use throughout life.

Authors: Mughal Shahnam Ali Baig , Hassan Abul , Hassan Ali Abul
Published: April 2023

This study aims to analyze the impact of religious narratives presented by Islamic scholars belonging to different sects on social media platforms. A large number of youngsters using social media platforms follow their favorite Islamic scholars on social media. Youth’s dependency for seeking religious knowledge through social media platforms has transformed from traditional religious learning to digital learning of religious knowledge. Different Islamic scholars' opinions on religious orders are being debated on social media, making it difficult for young people to decide which scholars to trust. Survey of 100 students, ages 18 to 30, from 6 leading universities will be given questionnaire. This study will incorporate cultivation theory to study respondents’ interpretation of religious messages by scholars using social media platforms. Participants were questioned about their knowledge of Islam, the impact of following an Islamic preacher had on their lives, their experience and perception about the digital preaching phenomenon, and whether or not those scholars helped them learn more about their respective religions believes and ideologies.

Authors: Zehri Abdul Wahid , Bhatti M K , Baloch Mir Sadaat
Published: April 2023

The process of entrepreneurship has a significant reputation for the career-related choice gained by innovation and risk-taking. The present study proposes to investigate the career decisions, opportunity recognition (ORN) and entrepreneurial intention (EIN) levels among university students studying sports sciences in Pakistan. The present study explores the EIN of young adults greatly associated to their career decisions and recognizes opportunism. The study employed cross-sectional data collected throughout Pakistan using a survey questionnaire. In total, 282 valid samples are utilized for concluding the investigation. By applying the path analysis through AMOS, the findings suggest a positive and significant effect of career decisions [(conscious career decisions (CCD) and blind career decisions BCD] on EIN among sports science students. Irrespective of this, environmental factors (ENFs) have an insignificant impact on EIN. The outcomes of a research study may provide guidelines for policymakers and universities’ authorities to accomplish and support the career development of students and accomplish the potential career catastrophes relating to the significant facts of unemployment issues and unemployed young adults. Moreover, the study would also assist the students in recognizing their career opportunities to tackle the unemployment trends. Further, the effect of ORN on EIN is also found to be positive and significant.

إن للمفسرين في مبحث دلالة المبين هدفا يختلف عن هدف الأصوليين، مع أن كلا منهما يبحث في نفس النص القرآني مستعينا بهذا المصطلح، وقد تولد عن هذا الاختلاف جملة من الإشكالات ترتبط بمفهوم ووظيفة المبين عند كل منهما، وتأتي هذه الدراسة بهدف رفع هذه الإشكال وذلك بإظهار مفهوم وهدف ووظيفة المبين عد كل من الأصوليين والمفسرين مع المقارنة، وقد فرضت طبيعة هذه الدراسة أن يعتمد الباحث على المنهج الاستقرائي التحليلي، وقد توصل الدراسة إلى مجموعة من النتائج أبرزها: أن وظيفة المبين عند المفسرين مختلفة عن وظيفته عند الأصوليين؛ ذلك أن: المفسرين يهدفون من خلاله إلى البيان والإيضاح وإزالة الإبهام؛ وصولا إلى المعنى الذي يحمله النص القرآني، وأما الأصوليون: فإنهم يهدفون من خلاله إلى إيضاح معاني القرآن وصلا إلى استنباط الأحكام الشرعية. أن التعريف الذي وضعفه الأصوليون للمبين يتلاءم مع منهجم في التفسير، وكذلك تعريف المفسرين يتلاءم مع منهجهم في التفسير. وأن المفسرين لم يعقدوا لدلالة المبين مباحث أو أبواب خاصة يتكلون فيها عن دلالته، وذلك عكس الأصوليين الذي عقدوا له مباحث خاصة به. وأوصت الدراسة بضرورة الاهتمام بهذا النوع من المصطلحات ودراستها دراسة؛ مستقلة من أجل إظهارها وتبسيطها وتقريبها في ثوب جديد للقراء والمهتمين.
قلق الأصالة وسطوة التجديد: مراجعة في المصطلح السردي مثالاً

اللغة أداة الفكر، والفكر رحمُها الأول، ولايمكن تصوّر أيَّة فعالية فكرية خارج حدود اللغة، ولو على نحو رمزي، لأَنّ اللغة قادرة على مَد التفكير بسلسلة من العلامات والرموز التي بوساطتها يستطيع نسج تأملاته العقلية البحتة، وهذا ما يستحيل تحقيقه خارج اللغة((فالتفكير والادراك يتحدان ويكونان قابلين للتوصيل من خلال اللغة فحسب، والتفكير واللغة يعتمد كل منهما على الآخر، ويتعذر الفصل بينهما)). من هذا المنطلق يسعى البحث لطرح مقدمة عن ماهية اللغة وسيرورتها الاجتماعية، وتأثير اللغات المجاورة في تكوينها، ليقف في آخر المطاف على مسألة غاية في الأهمية مفادها أنَّ التجديد أو التطور لا يتأتى للغة من رحم المفردات أو الألفاظ والصيغ الكلامية، بل لابد من فواعل تسهم في تفجير مكامن اللغة وجعلها في حالة دائمة من المخاضات لتوليد الألفاظ وشحن الدلالات وإعادة إنتاج ما أهملته الذاكرة الجماعية من اللغة، وبلا أدنى شك أنَّ أحد هذ المؤثرات هو الفكر، فالفكر يبادل اللغة سلسلة من الدلالات والمفاهيم والمعاني التي تظل بحاجة دائمة للخلق والابتكار في سبيل تحقيق السيرورة العقلية بوساطة اللغة، ولهذا سيقف البحث على جملة من الفواعل المؤثرة في تجديد اللغة وتطويرها.

هدفت الدراسة إلى التعرف على ضرورة الحذف في تخريجات النحاة في كتاب "ضرائر الشّعر" لابن عصفور، علماً أنّ الإشكالات في الشّعر العربي ظهرت منذ فجر نظمه؛ بسبب خروج بعض الشعراء عن القواعد التي أصَّلها النحاة، مما جعل كثيرا من النحويين يطلقون على ما خرج عن أقيستهم الضرورة الشعرية، أو لغة الشعر، التي تجوز فيه دون النثر. وتبدو أهمية الدراسة كون أنها تحاول الكشف عن أقوال علماء العربية في الأبيات الواردة في كتاب ضرائر الشّعر (موضع الدّراسة)، والوقوف على الأوجه الإعرابية الممكنة، والاستعمالات اللغوية التي ورد السَّماع بها، محاولا التوفيق بين ما يوائم القواعد المقرَّرة عند النحويين، وما عدَّه ابن عصفور وغيره أنه من الضَّرائر، وبين ما ورد منها في لغات العرب، متتبّعا آراء النحويين، واللغويين، بالدّراسة والترجيح بالأدلة في كلام العرب.

Investigating the microstructural development of cement-based materials is of fundamental importance for establishing a link
between micro-scale features and macroscopic properties. Conventional microstructural investigation by imaging methods based
on optical and electron microscopy has the intrinsic limitations of sample destructivity and lack of access to the 3rd dimension.
Such limitations can be addressed by the use of tomographic methods that allow a 3D in-situ observation of the time-dependent
microstructural properties of hydrating cement.
In this contribution, a series of CT-based methods applied to cement microstructure will be reviewed. Conventional lab X-ray
absorption tomography could be successively implemented to quantitatively assess a series of microstructural features, including:
analysis of the time-dependent phase evolution, topological description of the 3D pore network, air void pore size distribution,
definition of shape estimators for micro-encapsulated phase change materials.
Finally, it will be shown how the boundaries of microstructural investigation of cement materials can be pushed by means of
beamline techniques such as phase-contrast holotomography and diffraction-tomography.

Axial symmetry is a feature that often occurs in industrial parts. Analysing these with X-ray computed tomography (CT),
cylindrical coordinates about an axis fixed to the object form the most natural base to check certain characteristics of objects
that contain such symmetry. This work presents two methods to investigate this coordinate system and to incorporate it in the
current algebraic reconstruction framework and the analysis tools. The methods are applied to fast scans with few projections of
cylindrical products with slight random tilts. Standard reconstruction requires more advanced and hence slower techniques in the
analysis phase. Reconstruction in a symmetry adapted base needs precise knowledge about the object’s pose, but it allows aimed
sampling. This takes down the reconstruction and analysis time, which is necessary when applying CT for in-line inspection.

This work introduces methods for analyzing the three imaging modalities delivered by Talbot-Lau grating interferometry X-ray

computed tomography (TLGI-XCT). The first problem we address is providing a quick way to show a fusion of all three modalities.

For this purpose the tri-modal transfer function widget is introduced. The widget controls a mixing function that uses the

output of the transfer functions of all three modalities, allowing the user to create one customized fused image. A second problem

prevalent in processing TLGI-XCT data is a lack of tools for analyzing the segmentation process of such multimodal data. We

address this by providing methods for computing three types of uncertainty: From probabilistic segmentation algorithms, from

the voxel neighborhoods as well as from a collection of results. We furthermore introduce a linked views interface to explore

this data. The techniques are evaluated on a TLGI-XCT scan of a carbon-fiber reinforced dataset with impact damage. We show

that the transfer function widget accelerates and facilitates the exploration of this dataset, while the uncertainty analysis methods

give insights into how to tweak and improve segmentation algorithms for more suitable results.

Knowledge of the acquisition geometry is key for tomographic reconstruction. Before image reconstruction algorithms can be

applied to compute a 3D image from a set of 2D projections, calibration must be carried out to correct geometrical inaccuracies.

The main source of geometric misalignment can be attributed to possible mechanical instability and slight offsets in rotation and

translation of the source, detector and/or the sample stage themselves from the measured parameters. Although, many studies

have been dealing with the calibration problems for a specific X-ray CT system, most of those methods require specificallydesigned

and/or expensive phantoms. In this work, we introduce a low-cost, easy-to-use and readily available phantom, built

from LEGO bricks that serves as a structure to hold small, ‘metal’ beads for geometric calibration of a tomographic X-ray

system.

X-ray computed microtomography (microCT) that allows to extract quantitative 3D information about various objects is already
a well-established and widely used industrial technique for non-destructive testing, materials characterization and dimensional
metrology. On the other hand, modern developmental biology requires both qualitative and quantitative three-dimensional
information about the studied objects, which is not provided by conventional 2D imaging methods. In addition, the complexity
of biological structures often requires a more comprehensive methodology to compare shapes and sizes. Our approach is to
connect these two worlds, i.e. to apply procedures and analysis routinely used or developed for industrial computed tomography
to address scientific questions in developmental biology. This approach, which is based on the long-term experience of the
CEITEC BUT Brno micro/nanoCT research team on both, industrial and scientific application of X-ray microCT, brings new
possibilities in imaging, data processing and evaluation of 3D biological models. Here we present 3D structures that were
analysed by different approaches on the selected examples from developmental biology. In addition, quantitative analysis usually
used in industry were applied to segmented 3D models e.g. wall thickness analysis of facial cartilage, shape comparisons of nasal
capsules, automatic quantification of the cells in the salamander limb etc. A complete procedure consisting of staining, microCT
measurement and subsequent data processing is discussed.

In this research work we investigated the accuracy of a standard industrial robot. We wanted to find out, how accurate an X-Ray
Computed Tomography (CT) scan can be performed when using such a robot as a manipulator. The accuracy was measured
using a laser-interferometer. The measured deviations were used to run an X-Ray simulation via Fraunhofer EZRT’s Scorpius
X-Lab. Metrological analysis was performed as a measure for the quality of the simulated CT-scan. The metrological deviations
reflect the feasible accuracy of a CT-scan in a real CT-setup.
