Authors: Costa Matheus Aleixo da , Souza Fábio Luiz de , Rauber Rafael
Published: November 2024

O câncer de bexiga é uma neoplasia muito comum que assola principalmente a população masculina, em idade avançada e da raça branca, sendo seu principal fator de risco o tabagismo e seu principal sintoma a hematúria. Logo, traçar o perfil epidemiológico regional da doença é essencial para o diagnóstico precoce dessa patologia, visando um melhor tratamento que possa reduzir os índices de morbimortalidade da doença.  A história natural da doença evolui de uma metaplasia epitelial a um carcinoma invasivo, sendo o fígado, pulmões, ossos e adrenal os principais locais acometidos por metástase. O tratamento da doença na maioria das vezes é feito por meio da RTU (ressecção transuretral) de bexiga, podendo contar com o auxílio da terapia intravesical com onco BCG em alguns casos, vale destacar que a RTU é usada tanto para tratamento, como diagnóstico e estadiamento. Métodos: O presente estudo objetiva traçar esse perfil epidemiológico, juntamente com a identificação dos índices de mortalidade desta patologia no Paraná, propondo uma comparação com os parâmetros nacionais no período entre 2019 e 2022, utilizando dados do Departamento de Informática do Sistema Único de Saúde (DATASUS), com base em informações secundárias do Sistema de Informação sobre Morbidade Hospitalar do SUS (SIH/SUS). Resultados: O sexo masculino, de raça branca, entre a faixa etária de 70 a 79 anos e moradores da macrorregião norte do Paraná, são o perfil populacional mais afetados pela neoplasia maligna da bexiga no Estado. Este que possui uma taxa de mortalidade de ambos os sexos inferior em relação ao geral do Brasil, mas esta na segunda região do país com mais óbitos.

Abstract. Propane (C3H8) is an important trace gas in the atmosphere, as it is a proxy for oil and gas production and has a significant impact on atmospheric chemical reactions related to the hydroxyl radical and tropospheric ozone formation. In this study, solar direct absorption spectra near 2967 cm−1 recorded by a ground-based Fourier transform infrared spectrometer (FTIR) were applied to retrieve C3H8 total columns between June 2018 and July 2022 in Xianghe in north China. The systematic and random uncertainties of the C3H8 column retrieval are estimated to be 18.4 % and 18.1 %, respectively. The mean and standard deviation of the C3H8 columns derived from the FTIR spectra in Xianghe are 1.80 ± 0.81 (1σ) × 1015 molec. cm−2. Good correlations are found between C3H8 and other non-methane hydrocarbons, such as C2H6 (R=0.84) and C2H2 (R=0.79), as well as between C3H8 and CO (R=0.72). However, the correlation between C3H8 and CH4 is relatively weak (R=0.45). Moreover, the FTIR C3H8 measurements in Xianghe are also compared against MkIV measurements at several sites around the world. The new FTIR measurements in Xianghe provide us with insight into C3H8 column variations and the underlying processes in north China.
Alternate materials for the capture and quantification of gaseous oxidized mercury in the atmosphere

Published: November 2024

Abstract. Methodologies for identifying atmospheric oxidized mercury (HgII) compounds, including particulate-bound HgII (HgII(p)) and gaseous oxidized mercury (HgII(g)), by mass spectrometry are currently under development. This method requires preconcentration of HgII for analysis due to high instrument detection limits relative to ambient HgII concentrations. The objective of this work was to identify and test materials for quantitative capture of HgII from the gas phase and to suggest potential surfaces onto which HgII can be collected, thermally desorbed, and characterized using mass spectrometry methods. From the literature, several compounds were identified as potential sorbent materials and tested in the laboratory for uptake of gaseous elemental mercury (Hg0) and HgII(g) (permeated from a HgBr2 salt source). Chitosan, α-Al2O3, and γ-Al2O3 demonstrated HgII(g) capture in ambient air laboratory tests, without sorbing Hg0 under the same conditions. When compared to cation exchange membranes (CEMs), chitosan captured a comparable quantity of HgII(g), while ≤90 % of loaded HgII(g) was recovered from α-Al2O3 and γ-Al2O3. When deployed in the field, the capture efficiency of chitosan decreased compared to CEMs, indicating that environmental conditions impacted the sorption efficiency of this material. The poor recovery of HgII from the tested materials compared to CEMs in the field indicates that further identification and exploration of alternative sorbent materials are required to advance atmospheric mercury chemistry analysis by mass spectrometry methods.

Published: November 2024

Abstract. Criteria and indicators are frequently used for assessing the resilience of critical infrastructure (CI). Moreover, to generate precise information on conditions, the assessment designed for CI resilience could rely on indicator systems. However, few practical tools exist for guiding CI managers to build specific indicator systems for considering real cases. Therefore, the main objective of this study is to develop a step-by-step guide that contains guidance on operational steps and required resources for criteria and indicator setting, reference definition, and data collection. This guide enables CI managers to build systems of indicators tailored to different real cases. This guide could assist CI managers in their decision-making process, as it is structured based on a multi-criteria framework that takes into account the cost–benefit analysis and side effects of implementable actions. This guide could furthermore advance the application of indicator-based CI resilience assessment in practical management. In addition, this study provides an example to demonstrate how to use this guide. This example is based on specific circumstances for the Nantes Ring Road (NRR) network: when the ring road is flooded and closed, the road network manager suggests alternative roads to the public. An indicator system consisting of 4 criteria, 7 sub-criteria, and 11 indicators was built for these circumstances using the guide developed in this paper. This example relates to criteria and indicators in the technical, social, and environmental dimensions and involves 62 676 data points.

Abstract. Conventional methods of inorganic impurity analysis do not provide high enough depth resolution for many scientific questions in ice core science. In this study, we present a setup of laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) for high-resolution glacier ice impurity analysis to the sub-millimetre scale. This setup enables ice core chemical impurity analysis to a depth resolution of ∼182 µm while consuming only very small amounts of ice. The system performs simultaneous analysis of sodium, magnesium and aluminium incorporated in the ice matrix. In this case study within the framework of the WACSWAIN (WArm Climate Stability of the West Antarctic Ice Sheet in the last INterglacial) project, our method is applied to a selection of samples from the Skytrain ice core (West Antarctica) over a total length of 6.7 m consisting of about 130 single samples. The main goal of this study is to use the new LA-ICP-MS method to extract meaningful climate signals on a depth resolution level beyond the limits of continuous-flow analysis (CFA). A comparison between low-resolution CFA data and the high-resolution LA-ICP-MS data reveals generally good agreement on the decimetre scale. Stacking of parallel laser measurements together with frequency analysis is used to analyse the high-resolution LA-ICP-MS data at millimetre resolution. Spectral analysis reveals that despite effects of impurity accumulation along ice crystal grain boundaries, periodic concentration changes in the Skytrain ice core on the millimetre scale can be identified in ice from 26.8 ka (kiloyears before present, i.e. 1950 CE). These findings open new possibilities for climate data interpretation with respect to fast changes in the last glacial period and beyond, for example within the Beyond EPICA oldest-ice project.
Seasonal evolution of the sea ice floe size distribution in the Beaufort Sea from 2 decades of MODIS data
Authors: Buckley Ellen M. , Cañuelas Leela , Timmermans Mary-Louise , Wilhelmus Monica M.
Published: November 2024

Abstract. Arctic sea ice cover evolves seasonally from large plates separated by long, linear leads in the winter to a mosaic of smaller sea ice floes in the summer. The interplay between physical and thermodynamic mechanisms during this process ultimately creates the observed sea ice floe size distribution (FSD), which is an important metric for characterizing the sea ice cover and assessing model performance. Historically, the FSD has been studied at fixed locations over short periods, leaving a gap in our understanding of the spatial and temporal evolution of the FSD at large scales. Here, we present an automated framework for image segmentation, allowing the identification and labeling of individual ice floes in Moderate Resolution Imaging Spectroradiometer (MODIS) data. Using this algorithm, we automatically process and segment 4861 images, identifying more than 9.4 million floes over 23 years. The extracted characteristics of the floes – including area, perimeter, and orientation – evolve throughout the spring and summer in the Beaufort Sea. We find seasonal patterns of decreasing mean floe areas, increasing FSD power law slopes, and increasing variability in the floe orientation as the summer progresses.

Abstract. The share of wind power in power systems is increasing dramatically, and this is happening in parallel with increased penetration of solar photovoltaics, storage, other inverter-based technologies, and electrification of other sectors. Recognising the fundamental objective of power systems, maintaining supply–demand balance reliably at the lowest cost, and integrating all these technologies are significant research challenges that are driving radical changes to planning and operations of power systems globally. In this changing environment, wind power can maximise its long-term value to the power system by balancing the needs it imposes on the power system with its contribution to addressing these needs with services. A needs and services paradigm is adopted here to highlight these research challenges, which should also be guided by a balanced approach, concentrating on its advantages over competitors. The research challenges within the wind technology itself are many and varied, with control and coordination internally being a focal point in parallel with a strong recommendation for a holistic approach targeted at where wind has an advantage over its competitors and in coordination with research into other technologies such as storage, power electronics, and power systems.

A fetal investigation on the anatomical properties of opponens pollicis was not encountered in the literature in terms of surgical procedures performed in the early childhood period. In this context, this study aimed to examine the origin, insertion, and morphometric characteristics of opponens pollicis in human fetuses. Fifty-two sides of 26 fetuses (mean age: 24.08±4.22 weeks, sex: 11 males and 15 females) were dissected. The origin and insertion of the opponens pollicis were noted. The area, length, and width of the opponens pollicis were measured with the surgical microscope. Furthermore, according to the literature review, the origin and insertion of opponens pollicis were classified as seven and four types, respectively. The mean width, length, and area of the opponens pollicis were found as 3.28±1.15 mm, 7.12±2.44 mm, and 20.45±16.14 mm2, respectively. In this study, opponens pollicis most commonly started from the flexor retinaculum plus the tubercle of the trapezium (22 sides) and ended on the anterolateral side of the first metacarpal bone (41 sides). Fetal information related to morphometric characteristics and variations of opponens pollicis may be important for clinicians in reconstructive interventions on the thumb muscles in the early childhood period. Our classifications performed for the first time in the literature may guide future studies, especially those focused on thumb anomalies such as polydactyly and syndactyly.

Authors: EU Onofa Lucky , Adebowale Timothy , Gater Richard
Published: November 2024

Introduction: In developing countries with shortage of mental health professionals, non-physician primary health care workers are trained and supported to provide mental health services. One of the major challenges with mental health integration into primary health care (PHC) is the long-term sustainability of such services. This paper reports on a primary care mental health service that has been continuously sustained over a decade. Method: Aro Primary Care Mental Health Programme was developed and rolled out across 40 designated PHC centres in Ogun State in November 2011. Initially, 80PHC workers were trained using the adapted WHO mental health Gap Action Programme- Intervention Guide (mhGAP-IG) document covering 5 priority mental conditions: (Psychosis, Depression, Epilepsy, Anxiety Disorders & Other Significant Emotional Complaints and Substance Use Disorders). Over the years, above 400 PHC workers had been trained with commencement of mental health service delivery in the designated PHC centres. The field psychiatric nurse supervisors and consultant psychiatrists have provided a solid framework of support and supervision. Caseload of patients treated by the trained PHC workers was reviewed since commencement of the programme in November 2011 using descriptive statistics. Results: In the 11 years 6 months period (November 2011 – April 2023), the caseload of patients was 2,910 with an average of 254 new cases per annum. About 90% of the cases were Psychosis and Epilepsy. Attrition of trained PHC workers remained a major challenge with only 18 trained PHC workers remaining on the programme. Follow up cases of patients showed an average of 279 follow-ups per month. Conclusion: The Aro Primary Care Mental Health Programme has shown that it is feasible, practicable and cost effective with relevant stakeholders’ participation to scale up mental health services at primary care setting in Nigeria using the adapted mhGAP-IG document. Also the factors responsible for sustaining the services for over a decade are dynamic and deserved to be better understood

Во введении указана роль модифицирующих компонентов аппретирующего и армирующего действия на деформационные характеристики песчано-полимерного композита (ППК) на основе регенерированного полипропилена. Целью данной работы является установление влияния содержания компонентов ППК на деформационно-прочностные характеристики композитов, полученных термомеханическим совмещением связующего, наполнителя и модификаторов. Методикой исследований предусмотрено
изготовление и испытание образцов песчано-полимерного композита с повышенным уровнем прочностных характеристик в диапазоне предельной концентрации дисперсного наполнителя. В качестве объекта исследования использовали композиционные составы на основе связующего, представляющего собой смесь полиолефинов состава «полиэтилен высокого давления (ПЭВД) + полипропилен (ПП)» производства ОАО «Белвторполимер» (г. Гродно, Беларусь) в соотношении компонентов 1 : 3. Указан-
ное соотношение связующего выбрано с учетом высоких показателей деформационно-прочностных характеристик и низкой вязкости расплава ПП, а также необходимости повышения морозоустойчивости и показателей ударной вязкости ПП путем его модифицирования добавками ПЭВД, обеспечивающими стойкость композита к динамическим нагрузкам. Для формирования ППК применяли кварцевый песок фракции 180–260 мкм, обеспыленный путем промывки водной струей, с последующей его сушкой при температуре 95 ± 5 °С до содержания влаги не более 0,1 мас. % в сушильном шкафу ШС-80-01 СПУ. Обеспыленный кварцевый песок с целью увеличения адгезионного взаимодействия поверхности наполнителя и связующего подвергали обработке стеариновой кислотой. Исходный и модифицированный стеариновой кислотой песок смешивали с полимерным компонентом в виде хлопьев в заданных
соотношениях. В основной части представлены результаты испытаний прочностных характеристик полученных композитов на образцах квадратного сечения. Отмечено, что проведенные исследования деформационно-прочностных характеристик ППК, содержащих до 80 мас.% наполнителя, в условиях статических и динамических нагружений показали перспективность данного направления создания высоконаполненных полимерных композитов, создаваемых с применением регенерированных компонентов переработки полимерных отходов высокого качества. Применение аппретирования кварцевого наполнителя с помощью стеариновой кислоты обеспечивает повышение уровня прочностных характеристик ППК в диапазоне предельной концентрации дисперсного наполнителя, проявляющего полимерофобность в отношении полиолефиновых связующих.

A Brand Smooth World. The Aesthetic Sense in the AI Era
Authors: Drożdż Maja
Published: November 2024

The surprising speed of new technological progress leaves us guessing. It is worth asking questions about the consequences of AI development in the context of our aesthetic sense. Do AI and algorithms affect our perception of beauty? We already know that the filters in smartphones have a negative impact on the self-image of young generations. What happens, when the media are dominated by the “ideal” images generated by Mid Journey and Dall-e? What vision of reality do we create for the next generations and how to keep a human element in such a smoothed world? The AI aesthetic is visible not only in generated images, but also in texts generated by AI language models. It is omnipresent. Early consideration of pros and cons of AI in the context of shaping the aesthetic sense of the contemporary society gives us a chance to avoid some risks and use its potential instead. Keywords: new technologies, algorithms, artificial intelligence (AI), AI aesthetic, consequences of AI development

Authors: Sushil Kumar Pradhan, Ashok Kumar Sar
Published: November 2024

The growing concern for environmental, social, and governance has made ESG initiatives vital and feasible business endeavours. This research work seeks to measure the impact of ESG on Institutions ' financial performance (FP) by substituting the market-to-book value (MTB) ratio.  Indian hospitals between 2011 and 2020 were considered to evaluate the relationship between FP and ESG. To make their relationship more straightforward to understand in this paradigm, research has also been done on competition's possible moderating impact. The study concludes a strong negative correlation between FP and ESG. Additionally, it finds that using competition as a moderator considerably favours FP and ESG for Indian hospitals. This research concludes with a better understanding of the relationships between firm performance and ESG, which helps stakeholders and corporations build corporate strategies and investment decisions. This study is unusual because it investigates how competition impacts ESG and FP in Clinical Pharmacy.

Subject. Strategic sustainability of the enterprise. Goal. to analyze the micro- and macroeconomic conditions of enterprises’ activities and identify factors for analyzing their strategic sustainability. Method or methodology. In the process of achieving the set goal, methods of economic and mathematical analysis and strategic analysis were used. To study the operating conditions of enterprises, individual factors of the macro- and microenvironment, industry and competitive characteristics, and a single group of factors were used, which have different descriptions depending on the level of development of the external environment. The results of the work. The analysis allows us to systematize the conditions and factors for assessing the strategic sustainability of Russian enterprises and draw a conclusion about the need for assessment at four levels of the external environment. Conclusions. In the process of studying the category of «strategic sustainability», four levels of evaluation of the integral indicator were identified, which was reflected in the general economic and mathematical model of the strategic sustainability of the enterprise. The uncertainty of the external environment for individual industries and enterprises is growing, which is reflected in the assessment of their strategic sustainability. Uncertainty of the external environment, increased competition in the industry, microeconomic indicators of the enterprise – all this must be included in the general concept of the strategic sustainability of the enterprise. Failure to take into account external factors leads to most cases of bankruptcy of Russian enterprises and the inability of managers to clearly assess the external environment and adequately respond to its negative impact on the strategic position of the enterprise.

Published: November 2024

Gamified Mathematics Education (GME) offers a novel approach to mathematics instruction by integrating game mechanics and interactive technologies into digital learning platforms. This paper explores the theoretical foundations of GME, discussing its alignment with pedagogical theories such as constructivism and motivation models. It highlights the core components of GME, including the use of points, badges, levels, leaderboards, and real-time feedback, and how these elements foster student engagement and improve learning outcomes. Additionally, the paper examines the impact of GME on student motivation, performance, and collaboration, revealing significant improvements in comprehension and participation. While the benefits of GME are evident, challenges such as digital inequality, potential over-reliance on extrinsic rewards, and the need for teacher training are also addressed. The paper concludes with recommendations for optimizing GME implementation, emphasizing the importance of balancing educational content with game mechanics, improving access to technology, and providing professional development for educators.
El Cancionero de Sebastián de Horozco: estrategias autoriales del erotismo
Authors: Piquero Álvaro
Published: November 2024

This work explores how Sebastián de Horozco constructs throughout his poetry a multiform authorial image far from his biographical circumstances to satirise the most relevant social and literary characters of his time. The analysis of some relevant poems in this sense will show that Horozco is an essential link in the development of satire and eroticism as an authorial strategy, which will reach full of vitality to voices as multifaceted as those of Luis de Góngora or Francisco de Quevedo.
