Avances en la utilización del relieve y el color en los nuevos mapas táctiles de la Comisión Braille Española
Authors: Martínez Calvo F. J. , Iglesias Ramos S. , Reyes Llavero D.
Published: December 2024

Este artículo muestra la evolución que, desde 2009, han tenido los mapas en relieve, braille y color producidos en el Servicio Bibliográfico de la ONCE por la Comisión Braille Española (CBE) siguiendo las directrices de su Grupo de Trabajo de Materiales en Relieve. A raíz del inicio de una nueva colección de mapas físicos y políticos, se analizan brevemente las pautas que determinan el tratamiento de las distintas realidades geográficas a la hora de su adaptación al relieve, así como los últimos avances en el tratamiento y la mejora del uso que hacen del color. Ocho de cada diez personas afiliadas a la ONCE tienen un resto visual funcional que les podría permitir apreciar colores y formas en distintas circunstancias. Entre estas personas, un pequeño porcentaje ha perdido más del 90 % de su agudeza visual como consecuencia de un trastorno retiniano recesivo denominado acromatopsia, en el que los conos han perdido su función de receptores del color, por lo que no pueden percibir más que los distintos tonos de grises que van del blanco al negro. Como consecuencia de todo ello y gracias a las herramientas disponibles para la simulación de las diferentes discromatopsias, el Grupo de Trabajo de Materiales en Relieve de la CBE se propuso avanzar en este terreno a fin de que las personas afiliadas a la ONCE con problemas en la percepción del color pudieran explorar de manera más efectiva la nueva colección de mapas políticos en relieve y color que se inició en 2024. El artículo informa sobre los estudios y pruebas realizados y sobre la investigación de campo llevada a cabo para validarlos, así como sobre los objetivos logrados y los retos aún por solventar.

Simulation study of viable scenarios for potential numerical convergence issues in fitting joint models for longitudinal and survival data
Authors: De Oliveira Gonçalves Daiane , Da Silva Martins Fonseca Natália , Cirillo Marcelo Ângelo
Published: December 2024

Studies concerning the characteristics of phenomena/experiments over time, such as longitudinal studies or those focused on the time until an event of interest occurs, are increasingly essential in various fields. There may be instances where the investigation of the relationship between one or more longitudinal responses and an event of interest is warranted, a task achievable through the joint model of longitudinal and survival data. However, these models may have convergence problems and be computationally demanding, making their use unfeasible in many cases. In consideration of these factors, the objective of this study is to conduct a Monte Carlo simulation study involving various censoring percentages and correlation structures. The proposed cross-coverage probability will be employed as a diagnostic tool to identify circumstances conducive to numerical convergence, aiming to obtain maximum likelihood estimates for joint models applied to longitudinal and survival data. The results indicated similarity in terms of inference among the models, accounting for the impact of both the correlation structure and the censoring percentage. It was determined that the cross-coverage probability contributes to diagnosing the favorable behavior of the data, thereby facilitating the implementation of joint modeling.

Unraveling the Nesting Architecture and Foraging Behavior of Ceratina viridissima in the Sub-Tropical Terrain of Jammu
Authors: Choudhary Shallu , Sharma Devinder , Gupta Rakesh Kumar
Published: December 2024

Ceratina viridissima, commonly referred to as the small carpenter bee, serves as a crucial pollinator in both agricultural and horticultural crops. In this study, we investigated its nesting habits through controlled laboratory observations. Our examination focused on its nesting behavior within trimmed pithy stems of Rosa spp., Saccharum spontaneum and Saccharum bengalense. These bees exhibit polylectic behavior, gathering pollen balls from diverse sources for their brood cells, and engaging in nest protection activities. Nest construction involves the excavation of pith from various plant stems, resulting in distinct chambers housing eggs, larvae, pupae, and adults. The life cycle of C. viridissima spans approximately 43.77±2.13 days. Notably, pupal stages display a range of eye pigmentation. Foraging endeavors are predominantly observed from early morning to late evening, closely linked to sunlight and temperature fluctuations. Detailed analysis of nest architecture revealed chambers partitioned by septa. A comprehensive understanding of the nesting behavior and relatively short life cycle of C. viridissima across different plant hosts contributes significantly to their conservation efforts and underscores their potential for enhancing agricultural crop pollination practices.

Authors: Alruwaili Amal musallum , Elsayes Hala Ahmed , Alasmee Nofaa Ali , Sharif Loujain Saud
Published: December 2024

The psychological well-being of caregivers is crucial to enhancing their quality of life, which in turn increases the quality of care they deliver to patients with psychiatric disorders. The goal of the literature review was to find research that looked at caregivers of patients with psychiatric disorders and their perceptions of stress and coping strategies.

I conducted a systematic literature search between June 2021 and October 2021 to search for publications using the electronic databases. One hundred and thirteen studies were evaluated based on their titles and 54 articles were evaluated based on their abstracts.

Following title and abstract screening, 16 papers met the study’s goals (n = 16). In this review, most of the articles demonstrated the negative effect of stress and burden on the psychological states and well-being of caregivers of patients with psychiatric disorders and their quality of care.

The results showed that caregivers often utilize a combination of coping and maladaptive coping strategies to handle stressful situations, including emotion-focused approaches such as cooperation, coercion, negative religion coping,

and avoidance to decrease stress levels, and adaptive coping strategies such as the problem-solving approach.

Authors: Castro Castro Roger Antonio , Aguilar Maradiaga Marbell Danilo
Published: December 2024

Lantana (Lantana camara L.) es una de las especies ornamental que actualmente tiene mayor demanda en los mercados internacionales. Su forma de multiplicación es por esquejes para garantizar generaciones de nuevas plantas idénticas a la planta madre. Esta investigación se realizó en la finca Las Limas ubicada en el departamento de Estelí, km 153 carretera Panamericana, Nicaragua, durante el período de septiembre de 2022 a enero de 2023. Se experimentó con las variedades de Lantana “Copo de oro”, “Sonrisa de rosa” y “Pequeña amarilla”. Se evaluó el efecto de tres intensidades de luz (54, 130 y 200 µmol m-2 s-1) en el crecimiento de los esquejes; además se probó el efecto del fitorregulador Ethrel® 48 SL en dosis de 0, 25, 50 y 75 ppm para el control de la brotación floral y defoliación de esquejes; mientras que, para lograr la preservación fisiológica de los esquejes en condiciones de invernadero, se empleó el retardante de la maduración 1-Metilciclopropeno en dosis de 0, 2, 3 y 5 ppm. Con intensidades de luz de 130 µmol m-2 s-1 se obtuvieron mejores resultados estadísticos en comparación a la exposición a intensidad de luz de 54 µmol m-2 s-1 en las variables longitud de esqueje, longitud de la nervadura central de la hoja y número de raíces por esqueje. La adición de 75 ppm del fitorregulador Ethrel® 48 SL redujo la longitud de esquejes y longitud de entrenudos, pero se incrementó número de brotes por esqueje e inhibió la brotación floral. Con 7 ppm de 1-MCP las tres variedades de lantana presentaron los mejores resultados de las variables evaluadas, lo que favorece la obtención de plantas con buenas características morfológicas.
Displacement and Belonging: Redefining ‘Homeland’ and ‘Return’ among Crimean Tatars
Authors: Muratova Elmira
Published: December 2024

This article examines Crimean Tatar perceptions of ‘homeland’ and ‘return’ following the 2014 annexation of Crimea, contrasting these views with those of Crimean Tatars in exile after the 1944 deportation. I argue that while nearly all aspects of homeland perception among exiled Crimean Tatars – such as an identity marker, a mythologized final destination, and the place where their community reside – are still evident in the narratives of those displaced after 2014, their emphasis and meaning have shifted. For those displaced post-2014, Crimea is primarily viewed as the place where their community lives and where most aspire to return. This article is based on interviews with Crimean Tatar internally displaced persons (IDPs) in Ukraine and forced migrants abroad, contributing to broader discussions on agency, displacement and belonging.

Clitoria fairchildiana é uma espécie recomendada para a recuperação de áreas degradadas e arborização urbana. No entanto, há uma escassez de informações sobre a curva de embebição e a germinação das sementes de sombreiro. Este estudo teve como objetivo determinar a curva de embebição e avaliar a germinação da semente de sombreiro em função de volumes de água no substrato papel. Para o teste de germinação, foi adicionado ao substrato volumes de água equivalentes a 2,0; 2,5; 3,0 e 3,5 vezes a massa do papel seco, realizado na temperatura de 30 ºC. Foram analisadas as variáveis germinação, índice de velocidade (IVG), tempo médio (TMG) e frequência relativa de germinação (FRG). Os melhores resultados foram obtidos com o tratamento 2,5 vezes, que apresentou 90% de germinação, IVG de 2,66 e TMG de 8,5 dias. A embebição das sementes obedece ao padrão trifásico em um ciclo de 180h. O volume correspondente a 2,5 vezes a massa do papel não hidratado proporciona maior germinação em menor tempo.

As ligações estruturais de barras de aço coladas em madeira constituem uma opção vantajosa face às soluções usuais devido ao seu comportamento mecânico, durabilidade, comportamento ao fogo e a aparência estética melhorada. Apesar do seu grande potencial e da sua utilização ter sido iniciada há cerca de quarenta anos, ainda não existe consenso científico quanto às formulações numéricas para previsão da capacidade de carga presentes nas normas de dimensionamento de estruturas de madeira. O objetivo deste trabalho é investigar as influências de erros de execução e dos defeitos da madeira na resistência mecânica de ligações coladas entre barras de aço rosqueadas de diâmetro reduzido e madeira de Corymbia Citriodora. Os resultados mostram que não existiu influência de erros de execução e dos defeitos da madeira para valores de esbeltez da ligação acima de 5,0.
From Light Music to Jazz Việt: Jazz in the Print Media of Socialist Vietnam
Authors: Tan-Tangbau Stan B. H. , Nhàn Nguyễn Thanh
Published: December 2024

This article examines Vietnamese print media reporting on jazz between 1989 and 2001 that paralleled the emergence of live jazz performances in socialist Vietnam. Our analysis suggests that in the late 1980s, print media played a part in helping to affirm the status of jazz as a mainstream international music art form that recently became accepted as proper style in the sonic public culture of Vietnam. Following saxophonist Quyền Văn Minh's creation of Jazz Việt as an aesthetically nuanced sound, print media presented jazz as a genre performed by Vietnamese musicians that had embraced Vietnamese cultural elements and therefore suggested that the music should no longer be treated as strange to the ears of Vietnamese audiences. With this shift toward Jazz Việt, jazz in Vietnam was effectively placed in a position “between worlds,” located at the intersections of the domestic and international, the traditional and modern, and the Eastern and Western. By the end of the 1990s, however, Vietnamese print media began to lean toward a narrative that centered on the pioneering musician Quyền Văn Minh instead of the music itself. Our analysis is a timely reminder that the story of jazz in Vietnam awaits further study of the dynamics among musicians, audiences, and media professionals. This article is based on our examination of reports published in Vietnamese newspapers and periodicals between 1989 and 2001.

Bài này nhằm phân tích cách mà các bài báo Việt Nam viết về nhạc jazz được xuất bản vào giai đoạn giữa năm 1989 và 2001, cùng lúc với sự xuất hiện của các buổi biểu diễn nhạc jazz trên sân khấu Việt Nam. Nghiên cứu của chúng tôi cho thấy, vào cuối thập niên tám mươi và đầu thập niên chín mươi, báo chí Việt Nam đã đóng một vai trò nhất định trong việc xác nhận vị thế của jazz như một thể loại âm nhạc chính thống mà mới gần đây được chấp nhận là phù hợp với văn hóa âm nhạc Việt Nam. Sau khi nghệ sĩ kèn xắc xô phôn Quyền Văn Minh bắt đầu giới thiệu với khán giả trong nước những tác phẩm Jazz Việt do ông sáng tác, các báo chí Việt Nam mới dần phản ánh jazz như một thế loại nghệ thuật biểu diễn hàm chứa các yếu tố văn hóa Việt và một thể loại âm nhạc tồn tại trong đời sống âm nhạc của các nghệ sĩ Việt Nam, qua đó đề xuất là nhạc Jazz không quá xa lạ với các khán giả Việt Nam. Với sự xuất hiện của Jazz Việt, chúng ta có thể hình dung jazz ở Việt Nam đã được đặt vào một vị thế “giữa các thế giới,” tọa lạc ở các giao điểm giữa Đông và Tây, truyền thống và hiện đại và nơi gặp gỡ của quốc gia và quốc tế. Tuy nhiên, vào cuối thập niên chín mươi, báo chí Việt Nam bắt đầu chuyển hướng cách kể chuyện tập trung vào nhân vật nghệ sĩ tiên phong Quyền Văn Minh thay vì tiếp tục viết về sự phát triển của chính âm nhạc đó - nhạc Jazz.

Exploration of the Application of Biosensors
Authors: Zhu Ziyu
Published: December 2024

Biosensors are innovative devices that have gained significant attention for their ability to detect specific substances with high precision. They work by using biological elements like enzymes or antibodies that can uniquely recognize certain molecules, triggering a physical or chemical reaction when they interact with their targets. This reaction is then transformed into a measurable signal by another part of the biosensor, allowing for the detection and analysis of even minute quantities of substances. These tools are highly valued for their sensitivity and selectivity, meaning they can not only detect very small amounts of a substance but also identify exactly what that substance is. Their rapid response and reusability make them cost-effective and efficient. Biosensors find applications in various fields. In medicine, they can quickly pinpoint disease markers and monitor drug levels in the body, facilitating personalized treatment plans. In environmental monitoring, they play a crucial role in assessing water quality, identifying air pollutants, and detecting harmful substances in soil, thereby supporting environmental conservation and ecological oversight. Essentially, biosensors serve as specialized detectors, providing valuable insights for health and environmental well-being.

The Development and Future Trends in HCCI and DF-PCCI Engines for Sustainable Transportation
Authors: Bai Haoran
Published: December 2024

Internal combustion (IC) engines have long been the dominant technology in transportation, but their environmental impact, particularly in terms of air pollution, has become a growing concern. To address these challenges, advanced combustion technologies like homogeneous-charge compression ignition (HCCI) and dual-fuel premixed-charge compression ignition (DF-PCCI) engines have been developed. This paper explores the potential of HCCI and DF-PCCI engines to serve as more sustainable alternatives to conventional IC engines by analysing their combustion mechanisms, thermal efficiency, and emissions performance. While both engines offer significant environmental benefits, such as lower NOx, particulate matter, and CO2 emissions, they each face unique challenges in terms of fuel injection control, biofuel integration, and combustion stability. DF-PCCI demonstrates advantages in combustion phasing and high-load performance, while HCCI requires further development in fuel injection and exhaust gas recirculation (EGR) systems. Hybridization emerges as a promising solution to improve the flexibility and real-time control of both engines. Ultimately, this paper highlights the potential of HCCI and DF-PCCI engines to significantly reduce transportation-related emissions and contribute to global sustainability goals.
