Abstract (Objective) This paper presents the results of a qualitative, descriptive research study characterizing the knowledge of prospective mathematics teachers at the National University of Costa Rica (UNA) concerning the concept of mathematical proof, using the Mathematics Teacher’s Specialized Knowledge (MTSK) model. (Methodology) This research employed an interpretive paradigm and a qualitative approach. A questionnaire was administered to 42 mathematics teachers in initial training during the first semester of 2021, in the fourth and fifth years of the Bachelor’s Degree program in Mathematics Teaching at the National University of Costa Rica. Content analysis was utilized to study the answers provided by participants. Groupings of answers were created to generate central ideas about the concept of proof. (Results) Based on the results, four central ideas were found about the nature of mathematical proof for the survey participants. These ideas are similar to the formal logical-syntactic and mathematical aspects (LSMA) or informal semantic aspects (ISA). Evidence for the five De Villiers (1993) functions of a proof was found. Moreover, new functions related to them were discovered in mathematics and in school mathematics. (Conclusions) The results provide input to trainers of mathematics teachers and researchers for the review and analysis of teacher training programs. Additionally, they contribute to the search for new research areas related to this subject.

Abstract The article justifies a standard of proof for crimes against humanity. In order to achieve that objective, this investigation is divided into three parts. Firstly, it reflects the absence of an exhaustive explanation that justifies the application of a standard of proof in transitional justice. Secondly, it adopts an alternative procedural model as a method to set a flexible standard of proof, different from these used in criminal trials. Thirdly, it designs the argument of procedural asymmetries to expose two central aspects: the unjustified disadvantage suffered by the victim of crimes against humanity and the limitations of the legal sanction imposed for these crimes. Lastly, the article concludes that the application of a differentiated standard of proof is only possible in exceptional cases, such as those trials associated with serious human rights violations. objective parts Firstly justice Secondly Thirdly aspects Lastly cases violations

Resumen El artículo justifica un estándar de suficiencia probatoria para crímenes de lesa humanidad. Para lograr ese objetivo, la investigación se divide en tres partes. Primero, evidencia la ausencia de una explicación exhaustiva que justifique la aplicación de un estándar de prueba en la justicia transicional. Segundo, adopta un modelo procesal alternativo como método para fijar un estándar de suficiencia probatoria flexible, diferente de aquel usado en juicios penales. Tercero, diseña el argumento de la asimetría de las posiciones procesales para reducir la exigencia probatoria mediante la exposición de dos razones centrales: la desventaja injustificada que sufre la víctima de crímenes contra la humanidad y las limitaciones de la sanción jurídica impuesta por estos delitos. Por último, el artículo concluye que la aplicación de un estándar de prueba diferenciado solo es posible frente a casos excepcionales, como serían aquellos juicios asociados a graves violaciones de derechos humanos. objetivo partes Primero transicional Segundo flexible penales Tercero centrales delitos último excepcionales humanos

Abstract In the county of Pedra Lavrada - PB, various mineral occurrences of pegmatite are observed with prominence at Alto Dois Irmãos - PB, where quartz, feldspar and mica are mined. The understanding of mineral constituents is fundamental to define their industrial employment and to implement improvements in the beneficiation process. The proposal of this research is the detailed characterization and proof of that part of the ore (quartz) considered waste, presenting low poisoning (Fe2O3) and high silica (SiO2) content, to enable its industrial use. Besides that, to minimize the environmental impact through the reuse of this waste, and to determine the correct utilization of the milling equipment. For the pegmatite characterization, done were density determination tests, mineralogical identification by X-ray diffraction (XRD), chemical analysis by fluorescents X-rays and morphological analysis by scanning electron microscopy (SEM/EDS). Then tests were done for the Work Index (WI) calculous and consequently the empirical determination of the dimensions (LxD) of the pebble mill. The sterile presented a medium density of 2.66g/cm³, majority chemical composition of silicon and oxygen and quartz as the main mineralogical stage, indicating that this material has high purity. The. The Work Index (WI) was 15.9 kwh/t showing that this material can be considered resistant to breaking in the grinding process. The necessary energy to the milling was defined in 11.52 kwh/st, that corresponds to 57.28 HP. This power allowed the mill selection with diammeter and length of 1.83m, that provides the production maximization and the energy saving.

Road fatalities were labelled a pandemic as early as 1973 (BMJ 1973). The number of road fatalities reached 1.35 million in 2016. Currently over 3 500 people perish every day on the world's roads. South Africa has one of the highest road fatality rates in the world, with a fatality rate of 25.9 deaths per 100 000 population (WHO 2018). In order to understand and improve the road safety situation of a region, effective road safety assessments must be carried out. This paper presents a comparison of four different road safety assessment approaches, both traditional and novel, and serves as a proof of concept for the 'road safety desert' methodology, a new technique adapted from the 'transit desert' concept. This new approach to road safety assessment explores the possibility of geo-coded supply and demand comparisons to identify 'road safety deserts' - areas that have a comparatively higher road safety risk. This paper shows that there are several unique and effective ways to assess road safety, and that each approach incorporates different characteristics within their methodologies. It is recommended that road safety analysis is conducted using a multitude of methods, so as to improve understanding and intervention selection.

ABSTRACT Primary graft failure (PGF) is a known complication following penetrating keratoplasty (PKP). The usual approach to treat this complication is to repeat a penetrating keratoplasty. Here, we report a case of Descemet’s membrane endothelial keratoplasty (DMEK) for the treatment of PGF after PKP. A patient that underwent PKP, developed PGF with persistent graft edema and very poor visual acuity despite aggressive steroid use and a proof anti-viral treatment. Three months after the initial surgery, a DMEK was performed under the PKP graft. There was progressive early corneal clearing and, by the end of the first month, the patient already had no corneal edema. Uncorrected visual acuity (UCVA) improved to 20/40 and best corrected visual acuity (BCVA) to 20/20. DMEK may be an alternative to a second PKP for the treatment of PGF. This technique is a less invasive option when compared to the standard PKP procedure. (PGF .

RESUMO A falência primária do enxerto é uma complicação conhecida que pode ocorrer após o transplante penetrante de córnea. O tratamento usual dessa complicação é com um novo transplante penetrante. Apresentamos um caso em que foi usado o transplante endotelial de membrana de Descemet (DMEK - do inglês Descemet membrane endo-thelial keratoplasty) para o tratamento da falência primária após o transplante penetrante. Uma paciente submetida a transplante penetrante evoluiu com falência primária do enxerto a despeito do uso intenso de corticoide tópico e uma prova terapêutica de antivirais. Três meses após a cirurgia inicial, foi optado pela realização do transplante endotelial de membrana de Descemet sob o transplante penetrante. Houve um clareamento precoce e progressivo do enxerto com melhora importante da visão. Após um mês, a visão sem correção era de 20/40 melhorando para 20/20 com refração. O transplante endotelial de membrana de Descemet pode ser uma alternativa a um novo transplante penetrante como tratamento da falência primária. córnea DMEK endothelial endo thelial keratoplasty antivirais inicial mês 2040 20 40 20/4 2020 20/2 refração 204 2 4 20/ 202

Abstract The present study, exploratory and using document analysis, mapped the criteria established by 62 federal universities for eligibility, for students with disabilities, for the for the Sistema de Seleção Unificada [Unified Selection System] (SISU) quota policy. The public notices and terms of adherence of the 2019 selection processes, based on the fundamentals of the social model of disability, the Convenção sobre os direitos da pessoa com deficiência [Convention on the rights of people with disabilities] and the Lei Brasileira de Inclusão [Brazilian Law of Inclusion] (LBI), were analyzed. The results indicate that the norms align with the medical model and ignore the conception of the Convention and of the LBI. Despite being a unique process, there are significant differences in the criteria and the requirements for the proof of disability at each university, which may weaken the policy and the legal security of the candidates. study analysis 6 eligibility disabilities Unified System SISU (SISU 201 processes Brazilian Inclusion LBI, LBI , (LBI) analyzed process university candidates 20 (LBI 2

N,N-Dimethyltryptamine (DMT) is a serotonergic psychedelic that, when combined with monoamine oxidase enzyme inhibitors in the hallucinogenic beverage commonly known as ayahuasca, surpasses most common orally administered psychoactive drugs. There is a growing interest in the therapeutic potential of DMT due to recent clinical data showing the improvement of cognitive deficits associated with depression and Alzheimer’s disease. The development of analytical methodology for the monitoring of concentrations of DMT molecules to control the appropriate dosage for their use is essential for the treatment of patients. For this, we propose a novel flexible inkjet-printed paper substrate based on Au nanostars as proof of concept for DMT detection by surface-enhanced Raman scattering (SERS). The substrate was applied to detect DMT in water as a first approach to more complex matrices like ayahuasca beverages or blood samples. The optimization and performance of SERS substrates with different print cycles indicate that one print is enough to achieve the great performance of the flexible paper substrates. The SERS analyses for DMT in different concentrations, 10-3 to 10-10 mol L-1, reveal a high sensitivity of the sensors with a silhouette coefficient of 0.84 obtained by principal component analysis (PCA) statistical projections.

OBJECTIVES: The objective of this study is to determine if data science and machine learning methods can be effectively applied to the context of academic literacy teaching and learning and provide stakeholders with valuable decision support. METHOD: The method applied in this study is a variation of the knowledge discovery and data mining process specifically adapted for discovery in the educational environment. RESULTS: This study illustrates that utilising educational data can support the educational environment by measuring pedagogical support, examining the learning process, supporting strategic decision-making, and predicting student performance. CONCLUSION: Educators can improve module offerings and students' academic acculturation by applying EDM and LA to data collected from academic literacy modules. CONTRIBUTION: This manuscript contributes to the field of EDM and LA by illustrating that methods from these research fields can be applied to the South African educational context and produce valuable insights using local data, providing practical proof of its feasibility and usefulness. This is aligned with the scope of this journal as it pertains to innovations in information management and competitive intelligence.

ABSTRACT Purpose: Osteoarthritis (OA) is a degenerative joint disease which is categorized via destruction of joint cartilage and it also affects the various joints, especially knees and hips. Sinomenine active phytoconstituents isolated from the stem of Sinomenium acutum and already proof anti-inflammatory effect against the arthritis model of rodent. In this experimental protocol, we scrutinized the anti-osteoarthritis effect of sinomenine against monosodium iodoacetate (MIA) induced OA in rats. Methods: MIA (3 mg/50 μL) was used for inducing the OA in the rats, and rats received the oral administration of sinomenine (2.5, 5 and 7.5 mg/kg body weight) up to the end of the experimental study (four weeks). The body and organs weight were estimated. Aggrecan, C-terminal cross-linked telopeptide of type II collagen (CTX-II), glycosaminoglycans (GCGs), monocyte chemoattractant protein-1 (MCP-1), Interferon gamma (IFN-γ), antioxidant, inflammatory cytokines, inflammatory mediators and matrix metalloproteinases (MMP) were analyzed. Results: Sinomenine significantly (P < 0.001) boosted the body weight and reduced the heart weight, but the weight of spleen and kidney remain unchanged. Sinomenine significantly (P < 0.001) reduced the level of nitric oxide, MCP-1 and improved the level of aggrecan, IFN-γ and GCGs. Sinomenine remarkably upregulated the level of glutathione, superoxide dismutase and suppressed the level of malonaldehyde. It effectually modulated the level of inflammatory cytokines and inflammatory mediators and significantly (P < 0.001) reduced the level of MMPs, like MMP-1, 2, 3, 9 and 13. Conclusions: Sinomenine is a beneficial active agent for the treatment of OA disease.

Abstract: This article presents as a reading guide for the chapter “Temporality”, from Being and Nothingness, by Jean-Paul Sartre. To carry out the task, however, he articulates two complementary moments. The first moment works as a construction of an angle of attack and a way of approaching the Sartrean text in question. In it, the preliminary conditions for reading and the elements of readability of the problem are given, making it possible for the reader to install himself, so to speak, in the specifically Sartrean context of the question, thus offering the conditions for its reading, which also involves the way in which the theme is developed in previous investigations. In our opinion, it is these elements that, by providing analytical efficiency for reading the problem and clarifying the theme, make the text readable, a proof that is done in the second part of the article.

Abstract This paper presents a novel nature-inspired tri-band frequency selective surface (FSS) characterized by closely spaced bands, angular stability, and polarization independence. The FSS element adopts a segmented Fibonacci spiral geometry. While a single-segmented Fibonacci spiral does not inherently possess polarization independence, the proposed proof of concept achieves this by cascading the same design geometry rotated by 90° between them. Resonant frequencies of 1.63 GHz, 2.46 GHz, and 3.43 GHz are achieved, with minimal separation ratios of 1.5 from the second to the first frequency and 1.4 from the third to the second. Additionally, angular stability is confirmed up to 45°. Simulation of the FSS is conducted using HFSS software, and the simulated results are rigorously validated against experimental data, demonstrating excellent agreement. natureinspired nature inspired triband tri band (FSS bands independence singlesegmented single 90 them 163 1 63 1.6 246 2 46 2.4 343 3 43 3.4 achieved 15 5 1. 14 4 Additionally 45 45° software data agreement 9 16 6 24 2. 34 3.

Workplace-based evaluation is one of the most important, but challenging aspects of medical education. The aim was to improve the assessment of the rural community-based clinical training for undergraduate 3rd and 4th year family medicine students at the University of Namibia (UNAM) and implement a paperless process. An online module was developed on the Moodle platform to include a study guide, an electronic portfolio, and electronic resources (e-books and apps) to replace the current paper version of the logbook. We explored local resources by engaging with students and clinical trainers on how to best conduct the initial implementation. Engagement also entailed motivating students to actively participate in the implementation process. All 3rd and 4th year community-based education end service (COBES) students are now submitting proof of clinical learning electronically with the use of their phones in their online portfolio and using online resources. In addition, students in the practical family medicine module that has been introduced in the 6th year since 2023 are now also using an electronic portfolio and these assessment tools. CONTRIBUTION: Overall feedback from students and supervisors indicates a positive atmosphere of learning and constructive feedback on performance from all team members, hopefully improving work-based assessments and ultimately patient care. More members of the primary health care team were involved and the carbon footprint has also been decreased

ABSTRACT As a tool of proof and a tool of government, statistics played fundamental roles in the development of science, in the modes of action of the State, and in various branches of the economy. The development of digital technologies in the 21st century led to an increasing production of data and the emergence of a new algorithmic field of knowledge and action. Through empirical research grounded by theoretical contributions from the sociology of quantification and Science and Technology Studies, this paper analyzes some changes in public statistics produced by the National Statistical Offices. This is based on an investigation of the recent promotion of Big Data and Artificial Intelligence for official statistics in the context of the United Nations. government science State economy st Studies Offices Nations
