Authors: Damsted Camma , Skou Søren T. , Hölmich Per , Lind Martin , Varnum Claus , Jensen Hans Peter , Hansen Mogens Strange , Thorlund Jonas Bloch
Published: February 2024

OBJECTIVE: To compare the effect of early meniscal surgery versus exercise and education with the option of later surgery on pain, function, and quality of life in young patients with a meniscal tear, taking symptom onset into account.

DESIGN: Randomized controlled trial.

METHODS: In a randomized controlled trial (the “Danish RCT on Exercise versus Arthroscopic Meniscal surgery for young adults” [DREAM] trial), 121 patients aged 18-40 years with a magnetic resonance imaging–verified meniscal tear were randomized to surgery or 12 weeks of supervised exercise and patient education. For this exploratory study, the analyses were stratified by symptom onset (traumatic/nontraumatic). The main outcome was the difference in change after 12 months in the mean score of 4 Knee injury and Osteoarthritis Outcome Score subscales (KOOS4) covering pain, symptoms, function in sport and recreation, and quality of life.

RESULTS: Forty-two patients (69%) in the exercise therapy group and 47 (78%) in the surgery group were categorized as having a traumatic tear. We observed no difference in change in the KOOS4 after 12 months between the 2 treatment groups for either traumatic tears (18.8 versus 16.0 in the surgery versus exercise therapy groups; adjusted mean difference, 4.8 [95% confidence interval, −1.7 to 11.2]) or nontraumatic tears (20.6 versus 17.3 in the surgery versus exercise therapy groups; adjusted mean difference, 7.0 [95% confidence interval, −3.7 to 17.7]).

CONCLUSION: In patients with traumatic and nontraumatic meniscus tears, early meniscal surgery did not appear superior to exercise and education in improving pain, function, and quality of life after 12 months. Further research is needed to confirm the clinical applicability of these findings. J Orthop Sports Phys Ther 2024;54(5):340-349. Epub 22 February 2024. doi:10.2519/jospt.2024.12245

Authors: Vieira Tatiana , Barco Júlia , Paula Lucas , Félix Paulo , Bastos Jairo , Magalhães Lizandra , Crotti Antônio
Published: February 2024

We have evaluated eight p-coumaric acid prenylated derivatives in vitro for their antileishmanial activity against Leishmania amazonensis promastigotes and their antischistosomal activity against Schistosoma mansoni adult worms. Compound 7 (methyl 3,5-diprenyl-4-prenyloxycinnamate) was the most active against L. amazonensis (IC50 = 45.92 µM) and S. mansoni (IC50 = 64.25 µM). None of the tested compounds killed S. mansoni adult worms. Data indicated that the number of prenyl groups, the presence of hydroxyl at C9, and a single bond between C7 and C8 are important structural features for the antileishmanial activity of p-coumaric acid prenylated derivatives.
Perfluorooxosulfate Salts as SOF₄-Gas-Free Precursors to Multidimensional SuFEx Electrophiles
Authors: Zogu Armir , Ullah Karim , Spanopoulos Stefanos , Ismalaj Ermal , De Borggraeve Wim M. , Demaerel Joachim
Published: February 2024

Sulfur(VI) Fluoride Exchange (SuFEx) chemistry stands as a well-established method for swiftly constructing complex molecules in a modular fashion. An especially promising segment of this toolbox is reserved for multidimensional SuFEx hubs: three or more substituents pluggable into a singular S(VI) centre to make ‘beyond-linear’ clicked constructions. Sulfurimidoyl difluorides (RNSOF2) stand out as the prime example of this, however their preparation from the scarcely available thionyl tetrafluoride (SOF4) renders this chemistry only available to a select few laboratories with access to this gas. In this work, we identify silver pentafluorooxosulfate (AgOSF5) as a viable SuFEx hub with reactivity equal to SOF4. The AgF2-mediated oxidation of SOCl2 gives rise to the hexacoordinate AgOSF5 adduct, which in contact with primary amines produces the sulfurimidoyl fluorides in high yields. In addition, we have found this workflow to be fully extendable to the trifluoromethyl homologue, AgOSF4CF3, and we propose the use of AgOSF4X salts as a general route to azasulfur SuFEx electrophiles from commercial starting materials.
Trends in C1-C4 Alcohol Oxidation Activity Enhancement for Tunable Silicon Oxide Encapsulated Platinum Electrocatalysts

Published: February 2024

Electrooxidation of carbon monoxide (CO) and small oxygenate molecules is of great interest for direct alcohol fuel cell (DAFC) and electroorganic synthesis. Herein, we demonstrate that carbon-modified silicon oxide (SiOxCy) overlayers with nanoscopic thickness can greatly enhance the activity of Pt electrodes towards the oxidation of CO and five different oxygenate molecules. Trends in activity are reported with respect to the composition and structure of the SiOxCy overlayers, revealing that low-density, carbon-rich overlayers enhance peak current densities towards the oxidation of formic acid, methanol, ethanol, 1-propanol, and 1-butanol by 370%, 290%, 190%, 130%, and 30%, respectively, compared to bare Pt controls. Unlike conventional alloy electrocatalysts, the alcohol oxidation activity of SiOxCy|Pt electrodes did not strongly correlate with their ability to oxidize CO intermediates, suggesting that that C-H bond scission and/or oxidation of aldehyde or carboxylic acid intermediates, rather than CO intermediates, are the rate limiting steps during the oxidation of C1 and C2 alcohols. For larger alcohols like propanol and butanol, oxidation activity on encapsulated electrodes diminishes relative to bare Pt, which is attributed to mass transport limitations introduced by the overlayer. Overall, the structure-property-performance relationships uncovered in this study provide new insights into how overlayers can alter reaction mechanisms and can be used to guide design of encapsulated catalysts for alcohol oxidation and electroorganic synthesis reactions.
Revisionismo e negacionismo
Authors: Rollemberg Denise , Martins Cordeiro Janaina
Published: February 2024

Embora revisionismo e negacionismo sejam termos e conceitos que aludam a coisas distintas, não raramente são confundidos em estudos sobre diferentes temáticas e conjunturas. Este artigo procura diferenciá-los e analisar as razões e os processos a partir dos quais em muitos momentos os dois termos se confundiram. A questão ganhou visibilidade particular nas polêmicas em torno dos crimes nazistas na Segunda Guerra Mundial, mas envolve controvérsias anteriores e posteriores ao conflito. Tal realidade pode ser observada em três dimensões que, sendo autônomas, com frequência, se embaralharam: (a) política e ideológica; (b) historiográfica; (c) judicial. Envolvendo disputas do passado, a interpenetração dessas dimensões ocorre, sobretudo, quando estão em causa temas da história do Tempo Presente.
Installation and test procedure for frequency stability under cyclic loading of metals and alloys
Authors: Mylnikov V. V. , Dmitriev E. A. , Shetulov D. I.
Published: February 2024

Manufacture of parts operating under difficult conditions of cyclic loading, as well as products with stable dimensions necessitates the use of materials with minimal manifestations of inelastic properties. Study of these materials suggests conducting specialized narrowly focused tests using newly developed machines and installations with appropriate experimental techniques. We present the design, operation and control features of the original electromagnetic installation for testing fatigue and frequency stability and operating in a self- oscillating mode, which provides the equality of the frequency of cyclic loading and natural frequency of the sample. The system of the installation control contains two closed circuits: for excitation of self-oscillations and for stabilization of the oscillation amplitude. The sample is loaded by electromagnetic force, and unloading occurs due to the elastic forces of the material. The methodology and algorithms for calculating the stresses of samples of various geometric shapes for estimating changes in amplitude-frequency characteristics are presented. The calculated relationship between the force applied to the sample and its movement at the point of application of force is derived with subsequent determination of the stress by a known force. The results of calibration tests for the static mode of sample loading are presented and the forces acting on the sample (external, inertia, and elastic forces) are evaluated taking into account the maximum stress and maximum strain amplitude. Static and cyclic loading modes are compared. The frequency characteristics obtained during testing steel samples according to the proposed method are obtained. The experimental results of tests with interruptions in the process of cyclic loading and continuous testing are analyzed. It is shown that interruptions in cyclic tests lead to a jump-like increase in the frequency, whereas continuous tests revealed no jumps. At the same time, a comparative analysis with the results of continuous tests showed that the overall frequency deviation is approximately the same for the entire operating cycle in both cases. It is shown that an increase in the frequency after rest is random and does not depend on the number of operating cycles.

Dedication as a way of ontologization of the heterogeneity of modern English-language scientific discourse
Authors: Efimova Nadezhda Nikolayevna , Violina Marina Igorevna
Published: February 2024

The aim of the research is to identify the role of dedications in English scientific prose in ontologizing its heterogeneity. One of the paratext elements of modern scientific publications in English, i.e., dedication, was used as the language material. The scientific novelty of the research is as follows: for the first time, dedication has been investigated as a type of paratext in English-language academic discourse and the dedication examples representing personal discourse and acting as paratext elements in institutional discourse have been selected. The influence of dedication functions and characteristics on the ontologization of academic text heterogeneity has been empirically confirmed; the chosen methodology has been used for the first time to analyze authentic examples, which were not previously described from the perspective of the problem under study. The paper summarizes the key characteristics of scientific discourse that are important for identifying the correlation between the ways of heterogeneity manifestation and the structural element in which it is actualized. The research findings demonstrated the following facts: general classifications of dedications without differentiation by the text type are applicable to dedications of scientific texts, the latter contribute to the ontologization of the heterogeneity of scientific texts. In addition, the heterogeneity of scientific texts was shown to be reflected in the range of types of dedications and the variety of their functions, manifested to varying degrees depending on the type of the text itself, the type of dedication and the author’s intention.

Fostering teachers as sustainability and climate change educators through understanding of teachers' self-efficacy beliefs
Authors: Herranen Jaana , Aksela Maija
Published: February 2024

This is a mixed-methods case study aiming to understand teachers` self-efficacy beliefs for sustainability education in the context of climate change education. Therefore, we studied teachers` self-efficacy beliefs from their own perspective as well as the connection between self-efficacy and related concepts, perceived content knowledge (pCK) and perceived pedagogical content knowledge (pPCK). Twenty-two teachers from 18 countries participating on a climate change education professional development camp answered to a questionnaire, and 19 of them were interviewed using semi-structured interviews. The results of this study show that, according to the interviews, the studied teachers have willingness to continuous learn and develop their sustainability teaching. They have beliefs not only about sustainability education but also about themselves as sustainability educators, which is something that the future instruments on teachers` beliefs should acknowledge. The questionnaire results however showed that teachers had the lowest self-efficacy beliefs on supporting students` actions for sustainability. Teachers` pCK and their pPCK were shown to correlate with their self-efficacy, especially with items related to action. In conclusion, teacher education could focus on supporting teachers pCK and pPCK to develop teachers` action-related self-efficacy beliefs thus supporting students to act for sustainability.

Authors: Hasan Al , Chokroborty Mithun
Published: February 2024

This study makes an endeavor to experimentally find out the impact of credit concentration on DSE (Dhaka Stock Exchange) listed banks’ risk and return. Banking industry in Bangladesh is going through a turbulent situation due to increase in the size of NPL (Non-Performing Loan) which undermines banks’ profitability. The objective of this paper is to assess the impact of credit concentration on banks’ risk and return. We took Hirshmann-Herfindahl Index to measure the portfolio concentration, RoE (Return on Equity) as measurement of banks’ return and NPL (Non-Performing Loan) as measurement of banks risk. In this report we have collected data of five DSE (Dhaka Stock Exchange) listed private commercial banks from 2014 to 2018. We found that the concentration is highest in manufacturing, trade finance and readymade garments sector. Of the total loan portfolio of five banks from 2014 to 2018, 34% is concentrated in manufacturing sector, 19% is concentrated in trade finance, and 18% is concentrated in RMG (Ready Made Garments). The banks have lowest concentration in agricultural sector 2% of its total loan portfolio is given to agricultural sector on average during the period of study. Although concentration in SME (Small and Medium-sized Enterprises) sector, one of the most promising sectors in our country, is increasing but even then the portfolio concentration in SME sector is barely 8%. We regressed the concentration measure on banks NPL (Non-Performing Loan) and ROE (Return on Equity). The major findings we got are bank’s return and loan concentration is inversely related and this relationship is established at 5% significance level. However, insignificant relationship is found between loan concentration and NPL (Non-Performing Loan). The recommendations for the banking sector are banks should diversify their portfolio as it would yield more return for the shareholders’ of the banks, more extensive study is required to establish the relation between NPL(Non-Performing Loan) and loan concentration, bank should increase its size of portfolio in the SME (Small and Medium-sized Enterprises) sector which is a promising sector for an emerging economy, and banks should try to reduce their loan concentration to the optimum level for RMG (Ready Made Garments), trade finance and manufacturing industry.

Introduced in 2019, South Africa's carbon tax imposes escalating financial penalties on companies exceeding emissions limits, reaching up to six billion rand annually. This study examines the perceived competencies of Construction Project Managers (CPMs) in green retrofitting against standards set by the Council for the Built Environment (CBE) and the South African Council for the Project and Construction Management Professions (SACPCMP) and develops Cognitive Competency Theory (CCT), testing its tenets in reality. The research employs qualitative methods, interviewing thirteen experienced CPMs in green refurbishment. Findings reveal that CPMs are pivotal in balancing carbon tax demands and advancing sustainable development. However, they often lack a full understanding of their role in environmental protection and compliance with carbon tax regulations. The study concludes that while CPMs are essential in navigating the complexities of green retrofitting, there is a need for future research to explore the evolving role of CPMs in relation to regulatory pressures and industry standards. The Centre for the Built Environment emphasises that CPMs must possess competencies across various stages of project development, but sustainability competencies are not yet standardised in the industry.

Altered states of consciousness (ASCs), induced e.g. during psychedelic-augmented therapy, show great potential to treat highly prevalent mental health disorders like depression and posttraumatic stress disorder. However, such treatment approaches are not widely accessible due to legal, medical, and financial limitations. In this study, we explore the potential of circular breathwork to serve as a non-pharmacological and hence more easily accessible alternative to engage similar therapeutic processes. Scientific studies investigating the effects of breathwork on mental health are only just emerging and the underlying physiological and psychological mechanisms are largely unknown. In this study, we aim to address these questions by for the first time tracking physiological and experiential dynamics throughout the time course of a breathwork session, comparing two popular forms of breathwork: Holotropic Breathwork® and Consciously-Connected breathwork. We show that a reduction in end-tidal CO2 pressure due to deliberate hyperventilation is instrumental in catalyzing ASCs during breathwork. The ASCs evoked by breathwork were comparable to those produced by psychedelics, and their depth predicted psychological and physiological follow-on effects, including improved well-being and a reduction of depressive symptoms. Further analysis showed that different breathwork traditions impacted physiological markers as well as experiential and psychological outcomes in a similar way. Our findings identify physiological boundary conditions in which ASCs can arise in a non-pharmacological context, offering insights into the functional mechanisms of breathwork as well as its potential as a psychotherapeutic tool.
Comparisons of Addictive Behaviors Between First-Generation and Continuing-Generation College and University Students: A Scoping Review
Authors: Leslie R. Diandra , McGrath Daniel
Published: February 2024

Objective: This study aimed to synthesize research literature comparing first-generation and continuing-generation college/university students’ engagement in substance use and behavioral addictions (e.g., gambling). Methods: Six electronic databases and Google Scholar were searched for relevant peer-reviewed journal articles and student theses, dissertations, and scholarly projects. Results: Twenty-three articles were identified. All studies examined alcohol use. Ten studies also investigated non-alcoholic substances. No studies assessed behavioral addictions. Overall, findings were mixed, typically revealing no generational differences in substance use or a lower likelihood of substance use or misuse among first-generation students. However, several factors such as gender and race/ethnicity were found to moderate the student generation–substance use relationship, highlighting sub-populations who may be at an increased risk for problematic substance use. Conclusion: Findings emphasize a need for more research examining non-alcoholic substance use and behavioral addictions, as well as factors that may influence associations between generational status and addictive behavior engagement.
Using a foreign language increases risk-taking in medical decisions but not due to attenuated emotional responses

People take more risks when deciding in their foreign language. In three lab experiments (N=424), we explored two explanations of this phenomenon: reduced anticipation of regret, or increased accessibility of risk-increasing thoughts. Participants in native and foreign language considered two prenatal tests: a less sensitive but safe, and a more sensitive one – their task was to specify the level of risk of miscarriage of the more sensitive test while still choosing it. Three studies demonstrated greater willingness to take risks in a foreign language but this effect was not mediated by changes in the accessibility of thoughts or anticipated regret.

Teaching is the core of education and educational institutions focus to enhance the quality of teaching. There are various methods to controland enhance the quality. Our proposal is that, if teaching and assessment are multidimensional and integrated in a course; such educationalprocess will increase the level and quality of education. In formal education individuals come with their abilities which are mostly based onpre-gained knowledge. Prerequisite courses are fundamental and they perform background of individuals and influence their future successas well. According to various studies there exists strong relation among new knowledge and pre-existing knowledge. In the research sinceexaminations are used as indicator of gained knowledge, relation among previously implemented courses and actual courses is elaboratedwith respect to corresponding examinations. Using those relations, dimensionalities of an actual examination is determined for the quality interpretation of the actual course. Contribution of each of the prerequisite examinations is determined as impact of internal (implicit) dimensionality.On the strength of normally distributed grades of several congener courses, first pattern model is designated and it is compared with actualmodel. Research is realized based on different three cases. Purpose of the study is to compare actual model and expected pattern model,to describe the convenient acceptance level of the actual model for each of dimensions, and to determine the admissibility of the total impactof the internal dimensions of actual exam. In the article, quality of education process is interpreted with respect to the dimensionality of thecourse. Results of the analyses can be used as hints for the quality control in the education process.

Currently air plasma cutting is applied for cutting the tube ends at metallurgical enterprises. Plasma cutting process is accompaniedby the release of metallic dust and harmful emissions (NO, NO2, CO, O3) in the environment. During cutting the cuttingedges become saturated with nitrogen and oxygen and carburized. These phenomena promote increase of metal hardness ofthe cut surface and machining of pipe ends becomes complicated. To solve these problems, it is proposed to use superheatedvapor as plasma-producing media. Comparative research of ecological data and metallographic study of metal surface of thecutting edge were conducted. According to the research data, concentration of dust and gases is by 50-60% less during cuttingin water vapor as compared with the air plasma cutting; but when using protective water vapor curtain around the open portionof the arc this concentration is reduced to 70-75%. The depth of the heat-affected zone (HAZ) is reduced 3-3,5 times, and ofthe cast section 2,6-3 times. The microhardness of the metal surface in water vapor is reduced 1.7-2 times.
