Злокачественные новообразования мочеполовой системы занимают 12-14 место в мире в структуре онкозаболеваемости. В последние годы отмечен рост количество вновь выявленных больных во всем мире, также и в странах Центральной Европы и Азии [1,2]. Вместе с тем, необходимо отметить развитие и внедрение в рутинную диагностическую практику и новых технологий (КТ,МРТ, ПЭТ/КТ), которые в значительной степени улучшает качество и количество выявляемости онкопатологии среди населения. Особенно это актуально, когда новообразование в паренхиме почек являет собой случайную находку, без признаков манифестации, улучшая тем самым раннюю диагностику и предикторы ранней стадии заболевания [4]. В настоящее время, хирургическое лечение все еще остается основным методом лечения данной патологии [5,6]. И в этом ключе претерпело лишь модернизацию уже существующих оперативных методик и их различные модификации. Тем не менее в клинической практике достаточно распространены случаи так называемой «продвинутой» стадии заболевания, когда оперативное лечение ограничивается лишь гистологической верификацией клинического диагноза. Отдельно стоит упомянуть об рецидивных клинических случаях с поражением паренхиматочных органов и интракраниальными метастазами в головной мозг. В целом частота рецидивов по данным различный авторов варьирует в пределах 2,9-11% случаев и и возможность повторных оперативных вмешательств весьма ограничены [3,6]. В этой связи остро возрастает вопрос а лекарственной терапии, о ее лечебно-клинической и фармакоэкономической эффективности. Современная лекарственная терапия карциномы почки представлена лишь таргетными агентами (препараты различных групп ингибиторов тирозинкиназ), в виду доказанной неэффективности цитостатиков, иммунопрепаратов первого поколения (интерферон). Обширная группа ингибиторов тирозинкиназ демонстрируют различную общую выживаемость, медиану продолжительности жизни, бессобытийную выживаемость, а также частоту общего ответа.

Published: July 2024

Fulton’s condition factor (k) and the length-weight relationship (LWR) are the most important biological tools with respect to basic aspects of fish population dynamics; they are applicable to strategic plans for the conservation and management of fisheries. A total of 478 snappers Lutjanus peru and L. guttatus were analyzed in Santa Rosalía, Baja California Sur, in the Gulf of California. The total length of Lutjanus peru ranged from 21 to 55 cm, and weight ranged from 215 to 1,920 g, whereas total length of L. guttatus ranged from 21 to 59 cm, and weight ranged from 290 to 1,675 g. The LWR and condition factor were estimated for the two species and intraspecific factors were analyzed (sex, season, maturity stage) using Bayesian hierarchical models with random effects. The parameters of the LWR equation were similar for the two snapper species (α≈0.026 and β ≈ 2.8); they both presented negative allometric growth (p(β<3)>85%). The L. peru growth rate was greater in the warm season (p(βwarm>βcold)≈97%), whereas this difference was not as evident in L. guttatus (p(βwarm<βcold)≈72%). The condition factor k was greater than 1 for all categories in the two species (p(μk)=100%), which suggests that they keep a good body condition. This indicates that L. peru and L. guttatus in Santa Rosalía experience environmental conditions that benefit their body condition, as a function of year-round food availability. This information is useful for future conservation studies and for monitoring snapper captures, as most L. peru individuals caught were sexually immature.

Reasoning about possibilities: Modal logics, possible worlds, and mental models
Authors: Johnson-Laird P. N. , Ragni Marco
Published: July 2024

Everyone reasons about possibilities. This article explains how they could do so using mental models. The theory makes four major claims: 1. Correct inferences are necessary, referring only to facts or possibilities to which the premises refer and not ruling any of them out, for example: She left or hid; Therefore, it’s possible that she left and possible that she hid. 2. A possibility such as that she hid, which is represented in an intuitive model, presupposes the possibility that it did not occur, she did not hide, which, if reasoners deliberate, is represented in the resulting model. 3. Reasoners condense consistent possibilities, such as the earlier pair, into one possibility: it is possible that she left and she hid. 4. Inconsistencies, such as she left or hid, and she neither left nor hid, refer to no possibilities whatsoever – they have an empty model – and so their only effects are local. Hence, any inference can be withdrawn with impunity if there is knowledge to the contrary. Experiments have corroborated each of these principles. They are incompatible with four essentials of standard modal logics, which concern deductions based on “possible” or “necessary”. Their formal deductions correspond to valid inferences, which have no counterexamples in which the premises are true but the conclusion is false. And so the article examines the differences between the two approaches, and explores the adaptation of a modal logic to account for correct human reasoning. Its feasibility is an open question.

Ho Xuan Huong’s Nom Poetry and Its Significance to the Current Issues of Gender Equality
Authors: Van Vu Hong
Published: July 2024

Ho Xuan Huong was a famous Vietnamese poet who lived in the late 18th and early 19th centuries. She left behind many unique poems with a poetic style that is both thanh (right and pur vulgar) or tục (vulgar and dirty) and was dubbed “the Queen of Nom Poetry”. While nom poetry is a genre of poetry passed down from generation to generation without original text,  Huong is considered one of the unique poets of Vietnamese literature. Many of her works have been lost; up to now, her poems still in circulation are mainly oral Nom poems. Her poetic system focuses primarily on promoting the role of women under the harsh regime of the feudal dynasty which is expressed to honor women while mocking and pointing out the negative aspects of the regime of “trọng nam khinh nữ" (male chauvinism, to value men above women). Using qualitative research methods and referencing several previous studies combined with a survey of some historical data, is the main method of this research. Researching feminism in Huong’s nom poetry allows future generations to have a more complete and comprehensive view of the condition of women under feudalism, ideas that are ahead of their time and humanely profound; from there, determine its value and significance to the current issue of gender equality.

Authors: Núñez-Naranjo Aracelly Fernanda , Morales-Urrutia Ximena , Martínez-Jumbo Ariel
Published: July 2024

This study presents an analysis of the relationship between governance and subjective well-being in the Andean Community of Nations. The analyzed data is sourced from the World Values Survey of Wave 7. A quantitative approach was employed to investigate perceptions and political attitudes in the region. It highlights a positive, albeit slight, connection between subjective well-being and governmental trust, along with the positive influence of perception on wealth redistribution in well-being. Despite receiving subsidies, the unemployed consistently exhibit lower satisfaction levels. Significant associations were identified between governmental trust and opinions on wealth redistribution and surveillance. Additionally, political interest is positively correlated with the preference for men to excel in politics, indicating disparities in attitudes toward gender equality. These findings underscore the complex interaction between governance, well-being, and political perceptions in the Andean region.

Authors: Ibrahim Manal Abdulmunem ,   College of Pharmacy, University of Mosul, Iraq
Published: July 2024

Background. Gut microbiome may affect CNS, while an important neurotransmitter in migraine patients can be expressed in enteric neurons. Omega-3 PUFA (polyunsaturated fatty acid) and vitamin E are reported to decrease neuroinflammation, have beneficial effects on intestinal wall, and microbiota of the small intestine. This study aims to find the effect of omega 3 PUFA and vitamin E on intestinal permeability in migrainous, and their possible modulation effect on certain vitamins that have relations for both migraine and intestinal integrity. Methods. A total of 21 migrainous men are included in this study. Blood samples were drawn before and after intake of omega-3 PUFA and vitamin E supplementation softgel once daily for 30 days to compare with 13 apparently healthy men (control group). The blood samples are used to measure serum lipopolysaccharide, zonulin, amylase, vitamin B12, vitamin D, and albumin. serum lipopolysaccharide, and zonulin. Results. Body mass index, serum lipopolysaccharide and serum zonulin of migrainous men are higher, but vitamin B12 and vitamin D are lower than in the control group. Upon intake of supplement, serum zonulin and lipopolysaccharide are decreased in migrainous men indicating an improvement of intestinal integrity, but vitamin B12 and vitamin D showed no significant difference. Serum albumin and amylase showed no significant differences. Conclusion. Omega 3 PUFA and vitamin E supplements decreased intestinal permeability and can be a useful as an adjunct therapy for migrainous men because of its positive effect on intestinal integrity and gut brain axis, but it has no significant effect on vitamin B12 and vitamin D levels.

Neste estudo, examinamos como a posição no curso de vida, a disponibilidade de tempo, os recursos relativos em uma família ou as normas de gênero, em especial o que chamamos de respostas compensatórias ou neutralização dos desvios de gênero (gender display), determinam as desigualdades de gênero no trabalho reprodutivo entre casais brasileiros em 2019. Para esse propósito, foram utilizados os dados do painel da Pesquisa Nacional por Amostra de Domicílios (PNAD) Contínua do mesmo ano. Os resultados encontrados indicam que a posição no curso de vida tem um efeito muito mais forte sobre as mulheres, com a presença de filhos ampliando o tempo gasto no trabalho doméstico – embora esse tempo diminua à medida que a idade das crianças aumenta. O impacto das crianças nas jornadas reprodutivas das mulheres é o dobro do encontrado para os homens. Cuidar de pessoas idosas aumenta a carga de trabalho reprodutivo das mulheres, mas não tem efeito para os homens. Em termos de disponibilidade de tempo, o trade-off entre trabalho remunerado e não remunerado é bastante expressivo para as mulheres e pouco importante para os homens. As famílias mais ricas usam sua renda para adquirir no mercado bens e serviços que reduzem seu trabalho doméstico, mas o efeito de substituição é mais forte para as mulheres. Ao considerarmos homens e mulheres em um casal, encontramos que a capacidade de transformar recursos financeiros relativamente mais altos em horas de trabalho mais curtas – tal como preconiza a teoria da barganha – é determinada por normas tradicionais de gênero. Assim, mesmo quando as mulheres respondem pela maior parte da renda dos casais, elas continuam sendo responsáveis pela maior quantidade de trabalho doméstico, comportando-se de forma “tradicional” no espaço doméstico como uma maneira de neutralizar os “desvios” no mercado de trabalho (onde ganham mais que seus companheiros). A educação é um equalizador das relações de gênero, mas seu efeito é também determinado por papéis de gênero e raça. De forma geral, encontramos que normas e valores de gênero se constituem no fator mais importante para determinar o trabalho reprodutivo de homens e mulheres.

São analisadas as variações dos valores financiados pelo governo federal de internações no Sistema Único de Saúde (SUS), em 2019, segundo os procedimentos registrados no Sistema de Informações Hospitalares (SIH). São descritos o tipo de financiamento (teto de média e alta complexidade – teto MAC e Fundo de Ações Estratégicas e Compensação – Faec), a composição do faturamento (procedimentos principais, procedimentos especiais e procedimentos secundários) e a natureza jurídica dos prestadores de serviços. Observa-se grande variabilidade nos valores pagos para procedimentos com códigos idênticos e entre os distintos prestadores. Destaca-se o fato de que, apesar das críticas à Tabela SUS, somente a parcela de remuneração das internações organizada a partir dela permite visão clara dos critérios de pagamento. Estados e municípios financiam quase 60% das internações do SUS e pouco se conhece sobre os critérios de alocação desses recursos. É dado destaque também às implicações de reajustes lineares da tabela, que ampliariam as distorções, bem como à discussão sobre possível incorporação dos Diagnosis Related Groups (DRGs) à lógica de remuneração hospitalar. Os achados dessas análises poderão servir de ponto de partida para propor melhorias na Tabela SUS, inclusive complementando algumas das propostas apresentadas em relatório elaborado por um grupo de trabalho da Câmara dos Deputados sobre o tema.

Additionally, a Low-Pass Filter is integrated into the system and connected with charge pump, employing a technique that replaces resistors with transistors, thereby significantly reducing the overall circuit area. Furthermore, a Phase-Locked Loop (PLL) serves to eliminate the dead zone and significantly reduce the circuit's size. This project aims to advance circuit design methodologies by enhancing performance and minimizing area requirements.
Gravity Investigations Applied to the Geological Framework Study of the Mambasa Territory in Democratic Republic of Congo
Authors: MUTEBA DIBWE Patrice BONDO
Published: July 2024

This study concerns the gravity survey carried out in the territory of Mambasa in the province of Ituri in DR Congo, with the aim of studying its subsurface framework. We applied Free-Air and Bouguer corrections to the gravity measurements in order to eliminate gravity variations of non-geological origin. As for the graphical representation of the results, the spatial interpolation tools were useful to us in the elaboration of Bouguer anomaly maps. Then, we classified the study zone into Bouguer anomaly zones based on intensity. Gravity highs could indicate basement uplifts due to compressional movements. These uplifts would have led to the formation of granite domes which could be associated with mineralization. The enormous gravity depression would, for its part, be synonymous with a ditch or the presence of very low-density geological formations. The gravity profiles drawn support the analyzes of the maps: the anomaly curves are very fluctuating and uneven, highlighting several gravity highs and depressions. These fluctuations are probably induced by the presence of faults which separate the different anomaly zones.
Enhancing Estimating the Charge Level in Electric Vehicles: Leveraging Force Fluctuation and Regenerative Braking Data
Authors: Nandi Subimal , Dass Bikram , Chakraborty Rupak
Published: July 2024

Accurate determination of the state of charge is vital to optimize the performance and lifespan of electric vehicle batteries. Traditional methods which rely on battery models and direct measurements can be error-prone due to fluctuating operating conditions and battery degradation over time. Regenerative braking systems are crucial in electric and hybrid vehicles for improving energy efficiency by transforming kinetic energy into electrical energy during braking. However, force fluctuation is a challenge that can affect the performance and comfort of regenerative braking. It is known to us that electric motors and generators used in regenerative braking have non- linear torque characteristics, especially at low speeds, leading to inconsistent braking force. Variations in road conditions, such as wet or uneven surfaces, can affect the grip of the tires, leading to fluctuations in deceleration. Interactions of regenerative braking system with conventional friction brakes can cause force fluctuations, especially during the transition between the two systems. This study introduces an improved state of charge estimation technique based on force fluctuation and a regenerative braking system. This research shows that this approach significantly enhances state of charge accuracy compared to traditional methods, especially in urban driving conditions with frequent braking. The findings underscore the potential of using regenerative braking as well as force fluctuation condition data as a valuable input for state of charge estimation, ultimately leading to better battery management and an extended electric vehicle range.
Exploring school support stakeholders’ perceptions in identifying learning barriers: the case study of selected rural schools in the Eastern Cape
Authors: Jama Pateka , Buka Andrea Mqondiso , Naidoo Shantha , Moloi Tshepang Jacob
Published: July 2024

Identification of learning barriers is a critical issue for support provision in inclusive classes, as it informs individualised support plans for each learner who experiences barriers to learning. However, the school support stakeholders in Quintile 1 rural schools in South Africa face challenges in identifying learning barriers experienced by learners in their classes. Quintile 1 is a socially based ranking given to schools in poverty-stricken communities where most people are unemployed. This study focuses on identifying the perceptions of school support stakeholders in the identification of learning barriers in Quintile 1 rural schools. In this qualitative research study, a multiple case study design was used and 15 participants from three categories (teachers, principals, and school-based support team coordinators) were purposively sampled from three secondary and two primary rural schools due to the different roles expected from each category in the identification of learning barriers. Data were analysed using thematic content analysis. The findings revealed insufficient knowledge about the identification of learning barriers; lack of support in identifying learning barriers; lack of continuous in-service training on inclusive practices and education policies as barriers to the identification of learning barriers, which led teachers to perceive their roles in identifying learning barriers in a negative way. In general, this article contributes to understanding the complexities surrounding the identification of learning barriers for support provision in rural settings. It highlights areas for improvement in inclusive practices and supports structures to enhance the inclusivity and effectiveness of rural education systems.

Research suggests that beginner teachers face challenges when transitioning from pre-service to in-service teaching. Both nternational and local research found that transitioning from preservice to newly qualified teachers can be problematic. This study explores the learning experiences of beginner foundation phase Grade R teachers. The study utilises a qualitative research design embedded in the interpretivist paradigm. Data were collected from six foundation phase Grade R teachers using semi-structured interviews and reflective journals. The findings show that beginner teachers face enormous challenges early in their careers, and their sustainability in the classroom depends on how well they address these challenges. The findings have significant implications for the implementation of formal mentoring in practice.

The poor academic performance and literacy level of deaf learners in Namibia are a major concern, and it is necessary to understand the center of the situation. Even though deaf learners can become proficient readers and writers, the challenge remains in finding an appropriate instructional approach to attain these results. This presents an even greater challenge, as deaf learners not only differ from their hearing peers, but also significantly differ from one another in terms of their various familial and social contexts, language use, and overall holistic development. The Bilingual-Bicultural approach is considered a good approach for teaching deaf learners, and it offers them the chance to become biliterate; therefore this study explored the impact of a Bilingual-Bicultural literacy program on 41 d/hh learners (age = 7-13 yrs). Through a one-group pre-test post-test design, a group of participants were pre-evaluated, followed by an intervention and post-evaluation. The intervention's main goal was to implement practical teaching strategies using a Bilingual-Bicultural teaching approach that can reduce the delay and gap in language learning and literacy for deaf learners. Results from t-tests calculated to determine the statistical significance of the pre and post-test with regard to the total scores and all the sub-tests for NSL as well as Written English skills indicated significant results (p< 0.05). The study offers insight into the psychology of teaching deaf learners while also advancing the theory and application of the Bilingual-Bicultural approach. Additionally, it promotes debate of the best practices for ensuring that deaf learners receive a quality education and full participation in society.
¿Cómo crece la planta de café según la cantidad de frutos?
Authors: León-Burgos Andrés Felipe
Published: July 2024

Las plantaciones de café tienden a concentrar eventos de floración de gran magnitud en algunos años, lo que resulta en mayores cargas de frutos en los árboles, con posibles desbalances en la formación del área foliar. En Colombia, las plantas de café se caracterizan por presentar el crecimiento vegetativo continuo a través del año y de mayor magnitud en sincronía con los aumentos en la disponibilidad hídrica. Debido al alto potencial productivo de nuestras variedades y la forma como se presentan años de alta producción de café en los ciclos, eventualmente podría generarse un agotamiento, expresado en la zona productiva o quizás en toda la planta después de la cosecha. Sin embargo, las evidencias de los efectos del incremento de la carga de frutos en el crecimiento y desempeño agronómico de las variedades de café desarrolladas en Colombia, han sido poco estudiados. En este seminario se presentarán las respuestas fisiológicas y agronómicas de plantas de café sometidas a diferentes intensidades de carga de frutos a nivel del árbol, en una plantación establecida a plena exposición solar y ubicada en la zona central cafetera de Colombia.
La Agricultura Regenerativa: un nuevo enfoque para la producción sostenible de café en Colombia
Authors: Jaramillo Santiago
Published: July 2024

La agricultura regenerativa es un enfoque conceptual que busca mejorar la salud del suelo, la calidad del agua, la biodiversidad y aumentar la resiliencia climática de los sistemas agroalimentarios mediante la implementación de soluciones y prácticas basadas en la naturaleza. En el contexto actual de los sistemas de producción de café de Colombia, la agricultura regenerativa ofrece un camino prometedor para trascender más allá de las lógicas tradicionales de producción hacia modelos más sostenibles que cumplan con las exigencias crecientes de los mercados globales que demandan materias primas provenientes de sistemas regenerativos certificados. En respuesta a los nuevos desafíos que enfrenta la caficultura para aumentar la sostenibilidad económica, social y ambiental durante el proceso productivo del café, en este seminario se presentan los principales avances de investigación y recomendaciones prácticas desarrolladas por Cenicafé para promover la implementación de esquemas de manejo regenerativo del cultivo que se adapten tanto a las condiciones agroecológicas de las distintas regiones cafeteras como a las particularidades técnicas y económicas de los diversos sistemas de producción cafetera en Colombia.
Identity between Restricted Cauchy Sums for the $q $-Whittaker and Skew Schur Polynomials

The Cauchy identities play an important role in the theory of symmetric functions. It is known that Cauchy sums for the $q$-Whittaker and the skew Schur polynomials produce the same factorized expressions modulo a $q$-Pochhammer symbol. We consider the sums with restrictions on the length of the first rows for labels of both polynomials and prove an identity which relates them. The proof is based on techniques from integrable probability: we rewrite the identity in terms of two probability measures: the $q$-Whittaker measure and the periodic Schur measure. The relation follows by comparing their Fredholm determinant formulas.

Hydrogen chloride (HCl)—a key marker of the chlorine cycle on Mars—has been recently discovered in the Martian atmosphere by the ExoMars/TGO mission. In-orbit data indicate that this molecule appears in the atmosphere only in a limited time period and specifically in the southern summer season. A snapshot global mapping of HCl is indispensable to examine its sources and sinks, but such observations are not currently possible from any orbiters. Here, we present the first spatially resolved map of HCl obtained with the ground-based NASA InfraRed Telescope Facility. We find clear features of HCl, demonstrating that HCl is present close to the surface. HCl is detected in the equatorial region for the first time, revealing that HCl is widely distributed on Mars. However, the spatial distribution of HCl is not uniform, and it is enhanced in the southern polar region. Interestingly, this nonuniform spatial distribution of HCl column abundance is strikingly similar to that of water vapor column abundance. This highlights the important role of water vapor in the evolution of HCl through the atmosphere, as previously noted, and suggests its potential involvement in the atmospheric chlorine source processes.

In this article, we study a double phase variable exponents problem with mixed boundary value conditions of the form

   \begin{document}$ \left\lbrace \begin{aligned} D(u) +\vert u \vert ^{p(x)-2} u + b(x) \vert u \vert ^{q(x)-2}u & = f(x,u) \ \ \ \ \text{ in } \Omega,\\ u& = 0 \quad \quad \quad \ \text{ on } \Lambda _1, \\ \left( \vert \nabla u \vert ^{p(x)-2} u + b(x) \vert \nabla u \vert ^{q(x)-2} u \right) \cdot \nu & = g(x,u) \quad \ \text{ on } \Lambda _2 . \end{aligned} \right. $\end{document}

First of all, using the mountain pass theorem, we establish that this problem admits at least one nontrivial weak solution without assuming the Ambrosetti–Rabinowitz condition. In addition, we give a result on the existence of an unbounded sequence of nontrivial weak solutions by employing the Fountain theorem with the Cerami condition.
Scenarios for combating global warming: China's critical role as a leader in the energy transition
Authors: Schwartzman David , Schwartzman Peter
Published: July 2024

China is now the world leader with green capital actually creating renewable energy technologies. We address the possibility of whether China can emerge a new ecological civilization, as well as become the global leader to reach climate security. In particular, China has the potential to implement a solar energy infrastructure in the deserts of the Middle East as part of the Belt and Road Initiative, mainly in the form of concentrated solar power. The creation of this renewable energy capacity could supply electricity to much of the world, as well as power the direct air capture (DAC) of carbon dioxide with a permanent burial in the crust, in particular, using the ultramafic deposits in Oman. This realization would increase the chances of not breaching the International Panel on Climate Change (IPCC) warming target of 1.5 ℃, of course only if coupled with the termination of utilizing fossil fuels as early as possible and their replacement with renewable energy supplies globally. In this context, our pioneering model establishes that coupling a DAC-driven drawdown of atmospheric carbon dioxide with a rapid increase in the renewable energy capacity is more than capable of producing enough clean energy to eliminate energy insecurity globally (to all 8–10 billion humans) and to provide energy for the drawdown for the rest of the 21st century, thereby reducing atmospheric carbon dioxide to safe levels. This contingency will likely only be realized with a shift to demilitarization of the global economy. Likewise, this potential emergence of China as the global leader for climate security would likely inspire the push for a global Green New Deal to make this goal possible.

Pain is an essential aspect of the body's physiological response to unpleasant noxious stimuli from either external sustained injuries or an internal disease condition that occurs within the body. Generally, pain is temporary. However, in patients with neuropathic pain, the experienced pain is persistent and uncontrollable, with an unsatisfactory treatment effectiveness. The activation of the immune system is a crucial factor in both central and peripheral neuropathic pain. The immune response plays an important role in the progression of the stages of neuropathic pain, and acts not only as pain mediators, but also produce analgesic molecules. Neuropathic pain has long been described as a result of dysfunctional nerve activities. However, there is substantial evidence indicating that the regulation of hyperalgesia is mediated by astrocytes and microglia activation. Mesenchymal stem cells currently hold an optimal potential in managing pain, as they can migrate to damaged tissues and have a robust immunosuppressive role for autologous or heterologous transplantation. Moreover, mesenchymal stem cells revealed their immunomodulatory capabilities by secreting growth factors and cytokines through direct cell interactions. The main idea underlying the use of mesenchymal stem cells in pain management is that these cells can replace damaged nerve cells by releasing neurotrophic factors. This property makes them the perfect option to modulate and treat neuropathic pain, which is notoriously difficult to treat.
