Using a Witch's Hat to Avoid 'the Approved Pattern' : Finding Hope in a Pedagogical Stance That Fosters Quiet Resistance
Authors: Moore Rosie , Hermon Alison
Published: July 2023

In this article we share the work we have done as teacher educators in developing a third-year undergraduate module which nurtures our students to develop their own pedagogic vision and to consider themselves 'change agents' able to orient themselves within social and political structures
rather than merely adapting to the status quo. We locate our pedagogical approach within the current policy context where the core content framework (CCF) is required as the minimum entitlement for all teachers. We conclude with the notion that the positioning of pupils, teachers and teacher
educators as 'subjects' offers hope in collectively and quietly resisting a pedagogy and curriculum which appears to offer a limited way of being in the world.
The End of Surprise? The State of the Subject of Secondary English and Implications for Initial Teacher Education
Authors: Rock Brian
Published: July 2023

The chance to be part of educational experiences which provide dialogic spaces for the surprising or unexpected are essential for future English teachers and their pupils. The impact of neoliberal reforms on the secondary English curriculum and initial teacher education restricts teachers'
autonomy and pedagogical creativity whereby teaching approaches are reduced to approved processes, leading to monologic and repetitive learning experiences for young people. This has begun a process which, as philosopher Martin Buber would argue, denies the possibility of spontaneity and meaningful
expression in the classroom. In response, this paper reflects on my position as a former secondary English teacher and recently employed lecturer in initial teacher education. I set out a way forward where beginning teachers can be empowered to achieve a balance between external expectations
and their own values in relation to their subject and the pedagogical approaches they employ. To achieve this, we need to provide spaces for critical reflection on so-called 'best practice' in teaching and learning, especially for those at the beginning of their career.
Optimization of designing multiple genes encoding the same protein based on NSGA-II for efficient execution on GPUs
Authors: Kim Donghyeon , Kim Jinsung
Published: July 2023

In synthetic biology, it is a challenge to increase the production of target proteins by maximizing their expression levels. In order to augment expression levels, we need to focus on both homologous recombination and codon adaptation, which are estimated by three objective functions, namely HD (Hamming distance), LRCS (length of repeated or common substring) and CAI (codon adaptation index). Optimizing these objective functions simultaneously becomes a multi-objective optimization problem. The aim is to find satisfying solutions that have high codon adaptation and a low incidence of homologous recombination. However, obtaining satisfactory solutions requires calculating the objective functions multiple times with many cycles and solutions. In this paper, we propose an approach to accelerate the method of designing a set of CDSs (CoDing sequences) based on NSGA-II (non-dominated sorting genetic algorithm II) on NVIDIA GPUs. The implementation accelerated by GPUs improves overall performance by 187.5$ \times $ using $ 100 $ cycles and $ 128 $ solutions. Our implementation allows us to use larger solutions and more cycles, leading to outstanding solution quality. The improved implementation provides much better solutions in a similar amount of time compared to other available methods by 1.22$ \times $ improvements in hypervolume. Furthermore, our approach on GPUs also suggests how to efficiently utilize the latest computational resources in bioinformatics. Finally, we discuss the impacts of the number of cycles and the number of solutions on designing a set of CDSs.

Authors: Huang Kunlun , Jia Xintian , Li Cuiping
Published: July 2023

In this paper, we study a predator-prey system, the modified Holling-Tanner model with strong Allee effect. The existence and stability of the non-negative equilibria are discussed first. Several kinds of bifurcation phenomena, which the model may undergo, such as saddle-node bifurcation, Hopf bifurcation, and Bogdanov-Takens bifurcation, are studied second. Bifurcation diagram for Bogdanov-Takens bifurcation of codimension 2 is given. Then, possible dynamical behaviors of this model are illustrated by numerical simulations. This paper appears to be the first study of the modified Holling-Tanner model that includes the influence of a strong Allee effect.

Published: July 2023

The outbreak of the COVID-19 pandemic has affected the safety and well-being of healthcare workers. A scoping review was conducted to highlight the impact of COVID-19 on the safety, health, and well-being of healthcare workers and to shed light on the concerns about their perceived safety and support systems. A literature search was conducted in three different databases from December 1, 2019, through July 20, 2022, to find publications that meet the aim of this review. Using search engines, 3087 articles were identified, and after a rigorous assessment by two reviewers, 30 articles were chosen for further analysis. Two themes emerged during the analysis: safety and health and well-being. The primary safety concern of the staff was mostly about contracting COVID-19, infecting family members, and caring for patients with COVID-19. During the pandemic, the health care workers appeared to have anxiety, stress, uncertainty, burnout, and a lack of sleep. Additionally, the review focused on the suggestions of health care providers to improve the safety and well-being of workers through fair organizational policies and practices and timely, individualized mental health care.
‘Safety from Within’ An investigation into Lifeline - a funambulism project by Galway Community Circus, July 2022
Authors: Cadwell Stephen Joseph
Published: July 2023

This paper will attempt to show that the particular training techniques and styles used in youth circus (e.g. a place for everyone, no one is excluded, anything is possible, adaptability) and the approach to trainer training (e.g. having an emphasis on soft skills as well as hard techniques) are fundamental in allowing for this particular sense of community to develop and thrive.2022’s Lifeline performance is a particularly good example of these techniques and approaches. Lifeline was a funambulism spectacle organised by Galway Community Circus in July 2022, where 140 performers crossed the River Corrib on a series of highwires as part of the Galway International Arts Festival.Based on interviews with the organisers and participants, this paper will attempt to show that giving the participants a space for free identification, nurturing a healthy level of trust, and developing that trust into an appropriate tutor-student bond enabled 140 people to tight-rope walk across a river in Galway in front of thousands of people. Les personnes participant à des programmes de formation de cirque semblent être guidées par une émotion qui n’est pas directement liée à l’envie ou au désir. Elles ne semblent pas non plus vouloir éviter un sentiment de dégoût ou de peur, bien au contraire le plus souvent. Elles apparaissent davantage motivées par toute une mosaïque d’émotions autour des notions d’identification, de confiance et de tissage des liens. En d’autres termes, les participant·es sont porté·es par un véritable esprit de communauté.Cet article tente de démontrer que les techniques et les styles d’enseignement spécifiques aux arts du cirque pour un public jeune (par exemple, donner une place à chacun·e, n’exclure personne, montrer que tout est possible, apprendre à s’adapter), ainsi que l’approche adoptée pour former les animateurs et animatrices (par exemple, mettre l’accent sur le savoir-être et le savoir-faire) sont des aspects fondamentaux pour favoriser le développement de cet esprit de groupe.L’événement Lifeline illustre parfaitement la mise en pratique de ces techniques et de ces approches. Dans le cadre du Galway International Arts Festival, ce spectacle de funambulisme, organisé en juillet 2022 par le Galway Community Circus, a réuni 140 artistes sur plusieurs fils tendus au-dessus du fleuve Corrib. En s’appuyant sur les propos recueillis lors d’entretiens avec les personnes chargées de l’organisation et les participant·es, cet article vise à montrer qu’en donnant aux participant·es un espace pour s’identifier librement, favoriser ainsi largement la confiance et la faire évoluer vers une relation élève-professeur·e harmonieuse, 140 personnes ont pu traverser un plan d’eau sur un fil devant un public nombreux.
NONLINEAR HEART RATE VARIABILITY FEATURES IN DEPICTING THE EFFICACY OF RUTIN UNDER STREPTOZOTOCIN-INDUCED DIABETES MODEL WITH SUPPORT VECTOR MACHINE
Authors: Sinha Rakesh Kumar , Das Joyani , Mazumder Papiya Mitra , Aggarwal Yogender
Published: July 2023

Diabetes mellitus (DM) is a multifaceted disease that leads to higher cardiovascular events with neuronal damage, inflammation, and oxidative stress in subjects. It also causes an autonomic imbalance with the onset of the disease which disturbs the cardiac dynamics. This work demonstrates the rutin in treating the inflammation caused by hyperglycemia through nonlinear heart rate variability features in predicting diabetes using a support vector machine (SVM). The lead-I electrocardiogram was acquired from the control, experimental, and treated group of the male Wister rats ([Formula: see text] gm and age 10–12 weeks). A dataset of 669 samples was obtained from the recorded ECG signal and taken as input vectors to the SVM. The observed results presented an accuracy of 92.9% in classifying the control and experimental group. Further, the same model with the treated group dataset showed an accuracy of 7.7% (samples nearer to the experimental group) while 92.3% of samples were close to the control group. The findings suggested the efficacy of rutin drugs in restoring the blood sugar level and the sympathovagal balance. The usefulness of the non-invasive technique in the prognosis of the disease gives direction in the design and development of the computer-aided cost-effective wearable system. However, the need for expert clinicians cannot be ignored.
Isotherm and Kinetic Adsorption of Malachite Green Using Low-Cost Adsorbent of Coal Fly Ash
Authors: Nikmah Nadratun , Roto Roto , Mudasir Mudasir
Published: July 2023

In this study, isotherm and kinetic adsorption of malachite green (MG) using coal fly ash (CFA) as the adsorbent was investigated. This study aimed to examine the character of CFA analyzed by Atomic Absorption Spectrophotometry (AAS), Fourier-Transformed Infra-Red (FTIR), and X-Ray Diffraction (XRD) analysis. In addition, the adsorption of MG on CFA was also studied, including the effect of solution pH, adsorbent mass, contact time, and concentration of malachite green on the adsorption process. From the experimental data, the kinetic parameters isotherms and energy of the adsorption were determined. Kinetic study showed that the kinetic adsorption of MG on CFA fit well the Ho and McKay's pseudo-second-order, with an adsorption rate constant (k2) of 0.0377 g mg-1 min-1. Furthermore, the Langmuir isotherm model was the most suitable model to describe adsorption. Changes in the standard Gibbs free energy calculated from equilibrium constant (KL) at room temperature (303 K) showed that the adsorption process occurred spontaneously through chemical interaction (chemisorption) and most probably formed a monolayer on the surface of the adsorbent.
Optimization of Silicon Selective Leaching with Glycerol Using Response Surface Methodology (RSM)
Authors: Rianto Adam Kusuma , Prasetya Agus , Azis Muhammad Mufti
Published: July 2023

Selective removal of silicon might open-up the possibility of reusing silicon-contaminated spent catalyst. Unfortunately, study regarding this topic is still scarce. The effect of important parameters such as leaching treatment time and temperature was investigated, and the process conditions were optimized using response surface methodology (RSM) based on central composite design (CCD). Based on analysis of variance (ANOVA) results, leaching treatment time was found to be the most significant parameter, followed by temperature. Higher temperature and longer treatment time were satisfactorily enough for efficient silicon leaching from spent catalyst. The obtained quadratic model (R2 = 0.995) shows a good correlation between the predicted values and experimental data. The optimum condition for silicon leaching was identified to be a temperature of 213.3°C and a treatment time of 5.83 hours.
Kinetic and Isotherm Study on the Adsorption of Crystal Violet in Water Using Low-Cost Adsorbent of Coal Fly Ash
Authors: Riskiani Ermin , Aprilita Nurul Hidayat , Mudasir Mudasir
Published: July 2023

The kinetic and isotherm study on the adsorption of crystal violet (CV) on coal fly ash (CFA) has been studied. Before being used as an adsorbent, CFA was characterized with AAS, XRF, FT-IR, and XRD to determine the mineral components in CFA. The adsorption study of crystal violet in water with CFA includes the effects of solution pH, mass adsorbent, crystal violet concentration, and contact time on the adsorption process. The pseudo-second-order kinetic model best expressed the crystal violet adsorption behavior on CFA with the rate constant (k) of 1.24×10-1 g mg-1 min-1. The Langmuir isotherm model was found to be the best model to describe the adsorption, with a maximum adsorption capacity of 10.14 mg g-1 at room temperature. Based on the value of adsorption energy as well as the best isotherm model, the adsorption of CV on CFA forms a monolayer and can be classified as chemisorption.
Prediction of Rhodamine B Dye Content in Chilies Paste Using VIS-NIR Spectroscopy
Authors: Chairuniza Hannum Cintya , Jumeri  , Masithoh Rudiati Evi , Supartono Wahyu , Khuriyati Nafis
Published: July 2023

Chili is an agricultural product that is used as a spicy seasoning because it produces a hot effect with striking color and can be processed into various products, such as chili paste. However, it was found that some sellers misused the harmful Rhodamine B (RB) dye in chili paste to maintain the color in order to maximize profits without considering the health impact of consumers. In this study, a method was developed to predict RB in chili paste samples non-destructively using the VIS-NIR instrument combined with the Partial Least Square Regression (PLS) chemometric method to build a calibration model to measure RB content. Red curly chilies in good condition without blemishes were washed and then ground into chili paste products as samples in this study. The samples were divided into four variations of RB concentration, namely 0 ppm, 250 ppm, 500 ppm, and 1000 ppm. The chili paste spectra were acquired at a wavelength of 450-950 nm and several pre-treatments spectra were performed. The best calibration model that can be generated using pre-treatment multiplicative scatter correction (MSC) has a calibration value of R2 of 0.96, SEC of 70.69, and RPD of 4.52. This shows that a non-destructive method for predicting RhB concentrations in chili paste using VIS-NIR spectroscopy combined with chemometric analysis produces a good measurement method for screening applications.
Prevalence and determinants of Vitamin B12 deficiency among subjects with Type 2 Diabetes in a tertiary institution in Southeast Nigeria
Authors: Michael Chinweuba Abonyi , Theophilus Ejiofor Ugwu , Uzoma Chukwunonso Okechukwu
Published: July 2023

Vitamin B12 (Vit B12) deficiency is very common among diabetic subjects, although with variable prevalence. The aim of this study is to determine the prevalence of Vit B12 deficiency and its associated factors among patients with Diabetes Mellitus (DM). This study is important because Vit B12 deficiency is associated with metformin, which is a bedrock in the management of diabetic subjects. Since peripheral neuropathy is a recognized complication of DM, and also occurs in Vit B12 deficiency, it would be important to ascertain the role of Vit B12 deficiency in the emergence of peripheral neuropathy. Appropriate measures like vitamin supplementation would then be instituted in diabetics who are on metformin. A cross-sectional study was conducted at Enugu State University Teaching Hospital in Enugu, Nigeria, between January to July 2019. A total of 422 patients who fit the eligibility criteria were included in the study. Data on demographics, medication use, and anthropometry were obtained from each subject, while blood was drawn to study Vit B12 levels, Haemoglobin (Hb), Mean Cell Volume (MCV), and Glycated Heamoglobin (HbA1c). Vitamin B12 deficiency was defined as serum B12 level of ≤200 pg/mL. The prevalence of vitamin B12 deficiency among Type 2 DM patients was 16.6% (n=364). Predictors of Vit B12 deficiency in Type 2 diabetic subjects included duration of metformin use of more than five years (p<0.0001). Other predictors of vitamin B12 deficiency include Body Mass Index (BMI), diabetes duration, and macrocytic anemia. This study suggests that the prevalence of Vit B12 deficiency among patients with DM in our population is substantial. This is more frequent among patients who have been on metformin for more than five years.

The associations between interoceptive awareness, emotion regulation, acceptance, and well-being in patients receiving multicomponent treatment: a dynamic panel network model
Authors: Klocek Adam , Řiháček Tomáš
Published: July 2023

Mechanisms of change represent the cornerstone of the therapeutic process. This study aimed to investigate how network models could be used to test mechanisms of change at a group level. A secondary aim was to investigate which of the several hypothesized mechanisms (emotion regulation, interoceptive awareness, and acceptance) are related to changes in psychological well-being. The sample comprised adult patients suffering from psychological disorders (N=444; 70% women) from 7 clinical sites in the Czech Republic who were undergoing groupbased multicomponent treatment composed mainly of psychodynamic psychotherapy (lasting from 4 to 12 weeks depending on the clinical site). Data were collected weekly using the multidimensional assessment of interoceptive awareness, emotion regulation skills questionnaire, chronic pain acceptance questionnaire-symptoms and outcome rating scale. A lag-1 longitudinal network model was employed for exploratory analysis of the panel data. The pruned final model demonstrated a satisfactory fit. Three networks were computed, i.e., temporal, contemporaneous, and between-person networks. The most central node was the modification of negative emotions. Mechanisms that were positively associated with well-being included modification, readiness to confront negative emotions, activity engagement, and trust in bodily signals. Acceptance of negative emotions showed a negative association with well-being. Moreover, noticing bodily sensations, not worrying, and self-regulation contributed indirectly to changes in well-being. In conclusion, the use of network methodology to model panel data helped generate novel hypotheses for future research and practice; for instance, well-being could be actively contributing to other mechanisms, not just a passive outcome.

The workshop brought together researchers with expertise in areas of mathematics where model theory has had interesting applications. The areas of expertise spanned from expansions of o-minimal structures preserving tame geometric properties to expansions of specified fields by classical operators that preserve neo-stability properties. There were presentations and discussions on recent developments in definable groups and decompositions in relatively tame setups, the interplay of different notions of dimension and closure operators, and applications of the model theory of differential fields to diophantine geometry.
History of mathematics through collaboration: Toward a composite portrait of Oswald Veblen
Authors: Despeaux Sloan , Dumbaugh Della , Lorenat Jemma
Published: July 2023

Oswald Veblen played a pivotal role in the history of American mathematics in the twentieth century. His life, however, remains largely unstudied. This conference was designed to redress this issue by exploring Oswald Veblen and his contributions to the history of American and international mathematics in an interactive workshop that used the Veblen Papers from the US Library of Congress as a foundational and shared resource. With this frame, the conference raised queries and discussed issues related to Veblen, his mathematical contributions, and his collaborative initiatives, including his critical work aiding refugee mathematicians in WWII that helped establish long standing programs at American institutions that continue to advance mathematics at the highest level. The workshop echoed Veblen’s collaborative focus and brought together historians of mathematics and mathematicians to work alongside one another during the conference. This content and collaborative approach combined to advance our understanding of Veblen’s collaborations and the history of twentieth-century mathematics more broadly.
Antimicrobial Resistance (AMR) and Alternative Strategies for Combating AMR in Aquaculture
Authors: Bhat Raja Aadil Hussain , Altinok Ilhan
Published: July 2023

Antimicrobial resistance (AMR) in food production systems is regarded as a major threat to public health and nutrition security. Due to the potential for horizontal gene transfer, AMR in aquaculture might eventually spread to clinically important strains found in the environment, thereby affecting human health and the whole ecosystem. It is essential to comprehend the mechanisms driving AMR in aquaculture, including plasmids, integrons, and gene cassettes, to develop AMR risk management strategies. This review article presents an in-depth analysis of AMR in aquaculture and potential risks it presents to public health and the environment. The review provides a comprehensive understanding of the complexities of AMR by delving into the molecular and genetic factors that contribute to its spread. It also highlights the antibiotic usage pattern in different countries. The article also elaborates on alternative strategies that can be adopted to prevent and control fish diseases without negatively impacting the environment. This understanding may aid in the development of plans aimed at halting the spread of AMR and safeguarding public health. The various alternative approaches discussed in the review can offer potential solutions for controlling fish diseases in a manner that is both effective and environmentally safe for ecosystems and public health.
Aerodynamic Analysis of a Concept Truck and Trailer for Grain
Transportation
Authors: Zarpelon Fernando Luis , Balcewicz Luiz , Formolo Lucas , Guarda Ricardo
Published: July 2023

Brazil is significant grain (soy, corn, beans and rice) producer in the planet
and the road transportation is needed even when rail and maritime mode is
used.

There are opportunities to improve the grain road transportation efficiency. This
paper presents one opportunity which is the aerodynamic drag reduction and
therefore the fuel and energy consumption reduction on grain road
transportation.

This paper will discuss some alternatives to reduce aerodynamic drag on such
application considering Brazilian market regulation which has a low limit for
front axle load (lower than European regulation for instance) and limit the
total composition length. As an example of some alternatives to reduce drag
there is the frontal area reduction and trailer to cab gap reduction. Some of
those alternatives were implemented on a concept truck briefly presented on this
paper, which was tested on a real application, this paper will illustrate some
of those alternatives implemented.

Also, this paper presents the aerodynamic analysis using CFD and the strategy
used to run quicker analysis using steady state k-epsilon turbulence model
rather than transient DES, such strategy shows adequate correlation with wind
tunnel tests. Also, this paper briefly describes the strategy to correlate the
real application which has random yaw angles and air speed with CFD
simulation.

The authors intend that the alternatives to improve transported efficiency
presented in this work can influence the market and can be applied on the truck
grain transport application saving fuel/energy and cost which could be
translated on lower food cost and sustainable transportation.
Relation of Compression Residual Stress on Pre-Tensioned Surface in
Parabolic Leaf Spring Submitted to the Stress Shot Peening Process in Carbon
Steel
Authors: Chiqueti Cleber Michel , Manini Ricardo Guedes , Gomes Bárbara Miranda , dos Santos Marcos
Published: July 2023

This work deals with the effect of different blasting conditions under stress on
the intensity and distribution of compressive residual stresses. The tests were
performed on bars measuring 17 mm x 70 mm x 1700 mm in AISI 51CrV4 carbon steel.
The samples are considered parabolic leaf spring, as there is a variation in
thickness from the tip to the center, the thickness ay the center is higher than
tip thickness. The samples were laminated to their thickness in double roller
laminators, in order to obtain the desired thicknesses. The samples were
quenched and tempered in industrial scale furnaces. The pre-tensions were
calculated by the ANSYS® software and validated by characterization
with strain gauges, in a test condition of 1400 MPa of pre-tension. Tensile
tests and microstructure analysis were applied to ensure the specification in
terms of strength and microstructure. The stress shot peening process was
performed on a sample with flexural load at two points with a support distance
of 150 mm. The maximum bending pre-tension were 1450 MPa and 1750 MPa. Residual
stresses were measured by X-ray diffraction at five positions. Measurements were
made on samples with deflections and before detonation. Residual stress
measurements on a sample after heat treatment showed tensile residual stress
values. in the deflected samples, the residual compressive stresses increase
from the tip to the center of the specimen, this was demonstrated proportionally
with the validation of the extensometers, but it was not what was presented by
the ANSYS software, establishing differences in the pre-tension of the values of
the surface of the sample.

Published: July 2023

This paper presents a new product development cycle focused on moving the
simulation technology from the middle and late cycles of the design process to
the front of it. The main goal on this shift is to reduce the time-to-market and
costs while increasing the product innovation. The proposed workflow includes
the use of meshless technology in the concept definition phase of the design and
the use of the finite element method to validate the final version of the
design. The workflow was expanded to include the usage of test data to define
realistic load cases to correctly dimensioning of the component to accommodate
the project criterions. In this study the commercial software Altair SimSolid
and Altair OptiStruct were used to evaluate the proposed design structural
performance in the design proposals and the test data used to define the model’s
boundary conditions were obtained combining roads that represent the Suspensys
accelerated durability procedure. The resulting product from this workflow was a
pneumatic suspension bracket with the same mass as the original design but 5%
stiffer, demonstrating the effectiveness of the proposed methodology.

This document also covers the procedure description for the proposed development
cycle. Including the virtual model construction, a comparison between the
methods in terms of time and effort required to build the model in the
pre-processing phase, computational time, and cost to perform the calculation,
as well as the answers found during post-processing to ensure that the benefits
of implementing a new methodology will not compromise the accuracy of the final
result. Concepts needed to define the test duration and roads used on the
physical test and processing of the measured data will also be presented.

Bởi chuỗi số liệu khí tượng thực đo cho các yếu tố khí tượng ở cả 2 trạm đa số đều không tuân theo phân bố chuẩn nên chuỗi số liệu thể hiện các kịch bản khác nhau đã được khởi tạo bằng các kỹ thuật Monte Carlo, Latin Hypercube với mức độ chi tiết 5%, 10% và tứ phân vị dựa trên thống kê cụ thể của số liệu thực đo. Kết quả phân tích cho thấy 2 phương pháp hồi quy tuyến tính đa biến và ANN đều cho độ chính xác mô phỏng lượng bốc hơi ở mức cao (R > 0.93 hay R2 > 0.87), trong đó cấu trúc ANN với 1 lớp ẩn có 6 noron sử dụng hàm chuyển tansig là phù hợp để mô phỏng lượng bốc hơi cho cả 2 trạm. Sự biến động về giá trị trung bình và độ lệch chuẩn trong kết quả mô phỏng lượng bốc hơi thay đổi phụ thuộc nhiều hơn vào việc chọn mức chi tiết trong nấc xác suất phân bố của công tác khởi tạo so với việc chọn kỹ thuật khởi tạo. Trong một số trường hợp, kết quả mô phỏng lượng bốc hơi bằng ANN có giá trị nhỏ nhất mang dấu âm trong khi phương pháp hồi quy tuyến tính đa biến lại không có hiện tượng này.

O intenso processo de urbanização que se tem verificado nas grandes cidades, juntamente com o avanço tecnológico têm causado sérios problemas ambientais ao planeta, principalmente nos países menos desenvolvidos como é o caso de Angola. Nesse contexto, os resíduos sólidos tornaram-se num dos principais problemas a serem combatidos pela humanidade, uma vez que os mesmos são produzidos inevitavelmente nas actividades desenvolvidas pelo próprio homem. A busca por um novo padrão de desenvolvimento baseado no conceito de sustentabilidade tem-se tornado o foco dos processos produtivos. Assim sendo, energia e meio ambiente apresentam-se como sendo campos intimamente ligados, tanto em termos de pesquisa e desenvolvimento, como na implantação de tecnologia. Sistemas de biodigestão anaeróbica com geração de energia, mais especificamente a partir de resíduos sólidos urbanos, têm despontado como uma alternativa capaz de contribuir positivamente na busca por um novo padrão de desenvolvimento, uma vez que contribuem para solucionar problemas de emissão irresponsável de resíduos sólidos urbanos que reduzem desta forma os problemas de poluição ambiental. No presente trabalhos fez-se uma proposta do protótipo de biodigestor para obtenção de biogás apartir de resíduos sólidos orgânicos.

The metallurgical remains of San Tommaso, Pavia were used as teaching collections for a multi-disciplinary archaeometallurgy class  held by the first time in the academic year 2016/2017 at the University of Sassari. This paper, written by the lecturing academic, the academic advisor, and some of the students attending the course, wants to bring to the archaeometallurgical community some of the  observations and reflexions on this teaching and learning experience. The varied metallurgical assemblage recovered from the  excavation in 2013 of the Monastery of San Tommaso (Pavia) is a very useful teaching tool. In all, 23 samples were analysed and are  presented in this paper from at least six different metallurgical processes: cupellation, silver recovery, iron making (by the direct and  indirect method), copper alloying and casting. This variety also poses more complex questions for the archaeological/historical re-contextualisation of the findings which require a strong interaction between archaeologists and scientists in order to ensure the  “Pavia”most plausible reconstruction of events. In particular, we aim at introducing the importance of different perspectives in “questioning” the materials and in turn the scientific results.While presenting the results of the archaeometric investigations the main aim of the paper is to introduce the idea of the importance  of multi-disciplinary teaching in archaeometry, more specifically in archaeometallurgy, early on in the academic development (master or even undergraduate) instead of being the result of research at a later stage (PhD or even post-doc). The experience here presented,  shows that differences in languages and perspectives and peer-to-peer teaching offers an enhanced learning tool.
Circulation Patterns of Copper-Based Alloys in the Late Iron Age Oppidum of Třísov in Central Europe

Published: July 2023

This article presents an insight into the sourcing and circulation of copper alloys during the Late La Tène period in Central Europe  where the specialised production of metals is regarded as complex and conducted chiefly within the bounds of the oppida. Contrary to the logical, though not necessarily data-based, assumption that local raw materials for the production of bronze were mostly used from the local primary deposits, we argue that an advanced and complex economy of Late Iron Age allowed for the steady and consistent material supply even from distant areas and that such pattern was possibly commonly practised by the oppida sites.  Concurrently, we do not argue against the possibility of the exploitation and processing of the locally mined metal, we only point out that in provenance studies the evidence for that is yet difficult to find. We back our hypothesis by archaeometric analysis of the  assemblage of bronze objects from the oppidum of Třísov (Czech Republic) collected during the long-term investigations of this site. The selection of objects for analyses covers the spectrum from the local products to potentially imported items. A provenancestudy based on the analysis of lead isotopes and chemical composition has shown rather homogeneous pattern of lead isotopic values and, on the contrary, quite a variability among the chemical composition of the individual artefact groups suggesting thus 1)  standardised technological procedures for individual types of objects, 2) common recycling of the materials used and/or 3)  contamination of low-leaded alloys from highly leaded bronzes.
"Reliability Analysis of Axially Compressed Steel Columns "
Authors: Y B Madhusudhana , Govindaraju L
Published: July 2023

"In the past, the evaluation of the strength and safety of compressed steel columns has primarily relied on deterministic concepts. However, these concepts fail to account for the significant variability observed in buckling strength test results. This study aims to address this limitation by adopting a probabilistic approach to assess the buckling strength of steel columns; following the Indian standard specification IS 800-2007. In this investigation, the statistically variable nature of the material properties is considered by treating them as random variables and assuming a normal distribution. By incorporating this variability, a more comprehensive evaluation of the buckling strength can be achieved. The buckling strength of the steel column is computed using Merchant Rankine's formula, which takes into account deductive uncertainty. This formula considers various factors such as the slenderness ratio, live load to dead load ratio, and other relevant parameters to estimate the buckling strength of the column. Furthermore, the reliability of axially loaded columns is assessed using the First Order Second Moment (FOSM) technique. The effects of the slenderness ratio and the live load-to-dead load ratio on the reliability of the columns are specifically investigated and discussed. Overall, this study contributes to a more comprehensive understanding of the buckling strength of steel columns, incorporating statistical variability and providing insights into the reliability assessment of such structural elements."

Authors: Porto Susana , Marchão Amélia , Coelho Teresa
Published: July 2023

O presente artigo emerge de uma abordagem comparativa realizada num estudo de caso, investigação que objetivou avaliar o projeto internacional Kiitos@21st Century Preschools - projeto implementado no contexto de Educação Pré-Escolar e promovido pela Câmara Municipal de Ponte de Sor no âmbito do Programa Erasmus+. Os resultados que aqui se apresentam advêm de uma fase específica da investigação onde, de um ponto de vista metodológico, se pretenderam analisar as competências musicais construídas pelas crianças envolvidas nas atividades do projeto Kiitos@21st Century Preschools, comparando com outras crianças não envolvidas no projeto. Para o efeito foi aplicado o teste Primary Measures of Music Audiation (PMMA) de Edwin Gordon, de forma a aferir competências ao nível de perceção musical. Não obstante a diferença pouco significativa na percentagem de respostas corretas, as conclusões apontam para melhores resultados ao nível da perceção musical nas crianças envolvidas nas atividades do projeto relativamente às crianças do grupo de controle.

A ferramenta de trabalho de um atleta é o seu próprio corpo, sendo essencial um aporte de nutrientes adequado, de forma a melhorar o rendimento e recuperação do exercício. Neste contexto, muitos atletas consomem suplementos alimentares, apesar da eficácia da maioria deles não estar comprovada. Este estudo teve como objetivos principais determinar a prevalência e o tipo de suplementos alimentares consumidos pelos atletas e estudar a sua relação com a massa gorda/magra. Estudo quantitativo, transversal e analítico. A amostra era constituída por 72 futebolistas pertencentes a dois Clubes de Futebol, com uma média de idades de 21.44 ± 4.12 anos. Foi aplicado um questionário que incluia dados sociodemográficos, questões da prática desportiva, do estilo de vida e do consumo de suplementos alimentares. Foi ainda realizada uma avaliação da composição corporal a todos os atletas. Cerca de 91.7% dos atletas referiu tomar um ou mais suplementos alimentares (média de 4.71±3.04 suplementos/atleta) sendo as proteínas (84.8%), multivitamínico/minerais (72.7%) e o ómega-3 (50%) os suplementos mais reportados. Verificou-se que o consumo, e o total de suplementos consumidos não varia entre o género (p-value = 0.333 e 0.686 respetivamente). Relativamente ao tipo de suplementos consumidos, as proteínas (p-value = 0.040), ómega-3 (p-value = 0.040) e outros (p-value = 0.000), foram os suplementos que apresentaram diferenças estatisticamente significativas segundo o género. Encontraram-se diferenças estatisticamente significativas entre a massa gorda dos atletas e: creatina (p-value = 0.003), magnésio (p-value = 0.033) e outros (p-value = 0.001). Relativamente à massa magra e o tipo de suplementos, registaram-se diferenças significativas nos géis desportivos (p-value = 0.048), ómega-3 (p-value = 0.017), glutamina (p-value = 0.005), L-Carnitina (p-value = 0.019) e outros (p-value = 0.000). Considerando a elevada prevalência de consumo de suplementos alimentares entre os atletas futebolistas é necessário reforçar o acesso dos atletas à educação nutricional, onde se deverá enfatizar que uma alimentação equilibrada minimiza ou elimina a necessidade de suplementos.

Enquadramento: A experiência com a amamentação envolve ações de promoção, incentivo e apoio desde o período pré-natal, na maternidade e domicílio. A intergeracionalidade também exerce influência na experiência da amamentação. Objetivo: Identificar as experiências de duas gerações de mulheres sobre a amamentação do(s) seu(s) filho(s). Metodologia: Estudo qualitativo, exploratório-descritivo, numa amostra não probabilística constituída por 7 mães e 7 filhas que amamentaram ou amamentavam. Utilizou-se a entrevista semiestruturada e foi efetuada análise de conteúdo. Resultados: Emergiram cinco categorias: o processo de amamentação do filho; contributos dos enfermeiros na promoção, incentivo e apoio à amamentação; transmissão intergeracional de conhecimentos e aprendizagens sobre a amamentação; acontecimentos marcantes com o processo de amamentação. Conclusão: Os resultados ajudaram a identificar as experiências com a amamentação e constatou[1]se que as filhas atribuem significados mais positivos relativamente à geração anterior, o que releva a evolução favorável na promoção, apoio e incentivo da amamentação.

Published: July 2023

Na avaliação familiar é essencial o enfermeiro de família ser detentor de ferramentas facilitadoras do processo de avaliação. O Modelo Dinâmico de Avaliação e Intervenção Familiar (MDAIF) surge como resposta à necessidade de avaliação sistémica da família, efetivando assim os cuidados centrados na família. São objetivos do estudo avaliar uma família segundo o MDAIF, identificar as necessidades de intervenção em cada dimensão e estabelecer planos de intervenção. Como metodologia optou[1]se pelo estudo de caso, em que o processo de tomada de decisão foi sustentado na matriz operativa do MDAIF. Foram realizadas entrevistas à família e utilizados diversos instrumentos de avaliação como ferramentas de abordagem familiar. Como principais resultados destacamos que a família em estudo é reconstituída, formada pelo casal, o filho de ambos e dois adolescentes. Apresenta rendimento familiar insuficiente e conhecimento sobre gestão do rendimento não demonstrado. Revela problemas de comunicação, sendo o papel parental não adequado e as interações conflituosas. Este estudo possibilitou, assim, a identificação das necessidades da família e respetivas intervenções promotoras de mudança. Reconhecemos no MDAIF um excelente instrumento de trabalho, pois constituiu-se como modelo sistematizador e orientador dos cuidados de enfermagem à família.
