Rituales de fuego en la ciudad: La fiesta de San Juan en Murcia
Authors: Fernández Sánchez José Alberto
Published: February 2025

The celebration of the summer solstice through the customary bonfires is a practice rooted in Murcia since time immemorial. Their persistence in recent centuries, together with the incorporation of figurative elements to be burned in them, has given their development in the urban area a special significance. Although the most distant sources associate this practice with the old moorish neighborhoods, it is San Juan that has provided a specific framework for these popular rituals. There, in tune with the patron saint's festivities, it found special accommodation in the 20th century, reaching an unusual development towards the middle of the century through the incorporation of fallas of a valencian nature. The problem that arises from these uses is analyzed in this work in which, in addition, the decline of the celebration is studied in parallel to the destruction of the urban framework in which it acquired its nature as well as the forced dispersion of the neighborhood derived from that .

La celebración del solsticio de verano por medio de las acostumbradas hogueras es una práctica arraigada en Murcia desde tiempo inmemorial. Su persistencia en los últimos siglos, junto a la incorporación de elementos figurativos para ser quemados ha dotado a su desarrollo en el casco urbano de un significado especial. Si bien las fuentes más lejanas asocian esta práctica a los antiguos barrios de la morería, ha sido el de San Juan el que ha aportado un marco específico para estos rituales populares. En sintonía con las fiestas patronales, encontró allí especial acomodo en el siglo XX, alcanzando hacia la mitad de la centuria un desarrollo inusitado a través de la incorporación de fallas al estilo valenciano. La problemática que emana de estos usos es analizada en este trabajo en el que se estudia también la decadencia del festejo en paralelo a la destrucción del marco urbano y la dispersión del vecindario en el que el festejo adquirió carta de naturaleza.

Authors: Saruchera Bester , Bodhlyera Oliver , Mwambi Henry , Ndlovu Ntokozo
Published: February 2025

Breast cancer, increasingly prevalent in Zimbabwe, underscores the need to understand the involved axillary nodal status in diagnosed patients for assessment of disease severity and its potential progression. This study was undertaken to investigate factors influencing the number of axillary lymph nodes in breast cancer patients by identifying the best fitting count regression model, validated through bootstrap resampling. A retrospective analysis using hospital-based data for patients diagnosed with breast cancer at one of the two major referral hospitals in Zimbabwe was applied. We evaluated and compared count regression models – Poisson with Negative Binomial (NB), Zero-Inflated Negative Binomial (ZINB), Zero-Inflated Poisson (ZIP), Hurdle Negative Binomial (HNB) and Hurdle Poisson (HP) which are efficient in handling over-dispersed count data to investigate the various risk factors associated with involved axillary lymph nodes. Covariates included age, tumor size, tumor grade, estrogen receptor status, progesterone receptor status and HER2 status. Model diagnostics were assessed using Aikake Information Criterion and Bayesian Information Criterion. The ZINB and HNB models outperformed other models, with the HNB model demonstrating consistency across bootstrap-resampled datasets. Bootstrap resampling validated the reliability of model estimates, addressing biases caused by small sample sizes. Age was significantly associated with the zero-inflation component of the HNB model. This study highlights the importance of selecting appropriate count regression models for analyzing medical data and demonstrates the utility of integrating bootstrap resampling to ensure robust statistical inference. The findings provide actionable insights for therapy planning and resource allocation.

Published: February 2025

During the period 2020-2022 in the experimental field of Research Institute of Mountain
Stockbreeding and Agriculture – Troyan, a research experiment with bird’s foot trefoil (Lotus corniculatus
L.), cultivar Targovishte 1 was conducted to determine the impact of herbicide treatment on the basic chemical
composition of the forage mass. The experiment was set up using the block method with the following variants:
1. Control- untreated (C); 2. Kalam at a dose of 20 g/da; 3. Kalam at a dose of 40 g/da 4. Focus ultra at a dose
of 100 ml/da; 5. Focus ultra at a dose of 200 ml/da. Focus ultra herbicide (active substance cycloxydim 100 g/l)
at the dose of 100 ml/da was found to exhibit positive effect on crude protein content, quantity of crude fats and
mineral substances. The herbicide Kalam (dicamba 600 g/kg and tritosulfuron 125 g/kg) at a dose of 20 g/da
stimulated the amount of the macroelement calcium to the highest extent, while its higher dose increased the
phosphorus content in the biomass of bird’s foot trefoil. The two herbicides did not affect the amount of nitrogenfree
extractable substances (NFE). The favourable combination of high protein and low crude fiber determines
the herbicide Focus Ultra at a dose of 100 ml/da as suitable for application in the practice.

The issue of efficient forage production is gaining more and more economic importance and is
directly related to the breeding of forage crops with high productivity and adaptability. The aim is to create
new varieties of perennial grasses with high forage (hay, pasture and silage) and seed productivity, high forage
quality, and/or for ornamental purposes, with high adaptive potential. During the period 1966 - 2024, through
an ecologo-genetic approach and the application of classical and modern breeding methods, varieties of a wide
range of grass fodder crops were created at the Institute of Forage Crops - Pleven, the only specialized breeding
center for the country. A characterization of species and varieties of perennial grasses, for sown meadows and
pastures and for decorative purposes, which are certified and entered in the list of varieties of Bulgaria, EU

The aim of the study was to determine the effect of KCl salinity stress on germination characteristics
and early seedling growth of 5 populations of Aegilops biuncialis Vis. maintained in the ex situ collection of
the National Genebank of Bulgaria. Six different concentrations of KCl (50, 100, 150, 200, 250 and 300 mM)
were used as treatments and deionised water as control. To determine the salinity tolerance, the following
germination characteristics were studied: germination percentage (%), germination velocity coefficient,
germination rate index (% day-1) and mean germination time (day). Shoot and root length (cm), shoot and root
fresh weight (mg plant-1) and shoot and root dry weight (mg plant-1) were measured eight days after germination.
Relative injury coefficient, root and shoot height reduction and salinity tolerance index were also calculated.
The results showed that salinity prolonged the mean germination time and significantly decreased the studied
germination and seedling growth characteristics with increasing concentration of KCl. The inhibitory effect of
increasing KCl concentrations was stronger on root height reduction compared to shoot height reduction in all
populations studied except the population of BGR44617. The highest relative injury coefficient was recorded for
BGR44617, BGR44900 and BGR43660 when treated with 300 mM KCl solution, respectively, these accessions
were classified as susceptible for germination and seedling growth. BGR43667 was relatively the most tolerant
to salinisation with KCl at the seedling growth stage.

Authors: Holmstrup Sarah Adler , Lauritsen Jens Martin , Faergemann Christian
Published: February 2025

INTRODUCTION. Trend products such as trampolines and roller skates may result in child injuries. This study aimed to describe the development of product-related injuries and the pattern of lesions associated with six different trend products among children and adolescents in an urban Danish population from 1980 to 2021.

METHODS. We included all children and adolescents aged 0-17 years treated for injuries associated with bouncy castles, play stands, roller skates, scooters, skateboards and trampolines from 1980 to 2021. From the emergency departments at Odense University Hospital, Denmark, we extracted information on the date of injury, diagnosis and severity. We estimated annual incidence rates (IRs) for each product.

RESULTS. We included a total of 19,207 cases. The overall injury IRs per 10,000 population/years were 68.3 (95% confidence interval (CI): 67.0-69.6) for play stands, 21.9 (95% CI: 21.2-22.7) trampolines, 13.1 (95% CI: 12.5-13.6) roller skates, 8.0 (95% CI: 7.6-8.5) for skateboards, 7.0 (95% CI: 6.6-7.4) for scooters and 5.5 (95% CI: 5.2-5.9) for bouncy castles. Play stands had a high IR during the entire study period, whereas a significant peak in IR of trampoline injuries of 61.0 (95% CI: 57.6-64.6) and scooters of 18.5 (95% CI: 16.6-20.5) occurred in the 2017-2021 period. For skateboard, roller skate, scooter and play stand injuries, most lesions were located to the upper limbs. The lower limbs were the most frequently injured body region for the remaining products.

Validity of the Pancreatic Cancer Registry in Southern Denmark
Authors: Bhuller Cara Manmeet , Mortensen Michael Bau , Engberg Henriette , Fristrup Claus Wilki
Published: February 2025

INTRODUCTION. The Danish Pancreatic Cancer Database (DPCD) uses data from the Danish National Patient Registry (DNPR) and includes patients with pancreatic carcinomas, duodenal and ampullary cancers. Due to the aggressive nature of pancreatic cancer, some patients never receive diagnostic work-up at a hepato-pancreatico-biliary centre. The aim of this study was to explore the validity of the registration of the pancreatic cancer diagnosis for patients living in the Region of Southern Denmark reported in the DNPR but not included in the DPCD.

METHODS. This study is a descriptive analysis of a historical cohort of patients registered with a diagnosis of pancreatic cancer (DC 25.0-25.9, DC 24.1, DC 17.0, excluding DC 25.4) from 1 July 2019 to 30 June 2022, in the DNPR but with no registration in the DPCD.

RESULTS. We identified 155 patients with a relevant diagnosis in the DNPR who were not included in the DPCD. A total of 62 patients (40%) represented potentially valid cases of pancreatic cancer, whereas 73 patients (47%) had pNET and 20 patients (13%) had an entirely different diagnosis. Only seven patients (11%) of the potentially valid pancreatic cancer group and 4.5% of the total study cohort had a histology-verified diagnosis of pancreatic cancer. The DNPR contained (93/944) 10% with an incorrect diagnosis of pancreatic cancer and 6% with an uncertain diagnosis.

CONCLUSIONS. This study demonstrates a high level of completeness for the DPCD in the Region of Southern Denmark. Invalid registration of the pancreatic cancer diagnosis is an important limitation in using the DNPR, which is the only data source for identifying patients with pancreatic cancer in Denmark.

Millennial Women and The Paradigm Shift of Religiosity: a Case Study in an Urban Community
Authors: Tanamal Nini Adelina
Published: February 2025

This study adopts a library research method to analyze the paradigm shift of millennial women's religiosity in urban society. Through the exploration of relevant literature on religiosity, urbanization, technology, and gender dynamics, this research seeks to understand how millennial women adapt their religious beliefs and practices in the context of modern life. The main findings of this study show that millennial women in urban environments are starting to shift from traditional religiosity to a more personal, flexible, and more suitable form of religiosity that suits their contemporary lifestyle. This shift is influenced by a number of factors, including urbanization that causes changes in the social environment, technological advancements that facilitate access to information and interaction, and the influence of social media that allows women to shape and spread their own narratives of religiosity. In addition, the demands of gender roles also play an important role in how millennial women navigate their religious lives amid various social and family responsibilities. Millennial women not only function as recipients of religious values, but also as agents of change who are active in shaping and updating religious practices that are more inclusive and relevant to the challenges of the times. Thus, this study not only makes a theoretical contribution to the understanding of millennial women's religiosity, but also opens up opportunities for further empirical research to delve deeper into the dynamics of religiosity in urban society.

Minería ilegal: Una amenaza para la seguridad integral y el desarrollo sostenible del Ecuador
Authors: Cueva Jiménez María Gabriela , Larrea Romero Luis Antonio , Guaillas Chuquimarca Luis Alberto
Published: February 2025

Esta investigación examina la minería ilegal como una amenaza significativa para la seguridad integral en Ecuador, enfocándose en los enclaves productivos existentes que han dado lugar a gobernanzas criminales en el territorio. Estas gobernanzas surgen de la convergencia entre la minería ilegal y otros delitos, incluyendo el crimen transnacional. El Estado ecuatoriano ha clasificado la minería ilegal como una amenaza, debido a la formación de espacios geográficos bajo el control de poderes criminales, donde se concentran múltiples actividades ilícitas. Estos focos de tensión se integran a la cadena productiva de la minería ilegal, implicando delitos como el tráfico de armas, municiones y explosivos, narcotráfico, lavado de activos, trata de personas y contrabando de combustibles. Además, se observa una corrupción sistemática que involucra tanto actores privados como comunidades indígenas y organizaciones delictivas, lo que genera enormes beneficios económicos para estos grupos. Este fenómeno impacta gravemente la economía y el desarrollo sostenible del país, comprometiendo su estabilidad y seguridad integral.
Biomechanics of helmet mask structures in mitigating explosion-induced traumatic brain injury: A numerical simulation study
Authors: Ma Xuan , Yang Bin , Zheng Yang , Gao Feng , Zhou Ronghua , Zou Jiajia , Zhang Xingyu
Published: February 2025

Traumatic brain injury (TBI) caused by explosions is the most common injury suffered by front-line soldiers. However, research on protective gear has primarily been limited to different types of helmets or their internal padding systems. Aerogels, with their microporous structures and high acoustic impedance properties, can effectively buffer the impact of explosions and generate significant acoustic mismatches between adjacent layers, making them promising materials for reducing the damage of blast shock waves to the head. This study aims to enhance the performance of protective equipment in mitigating explosion-induced head injuries and proposes a novel helmet mask structure based on polycarbonate and aerogel laminated composites. The coupled Eulerian-Lagrangian (CEL) method in Abaqus is employed to analyze the mechanical responses of different helmet-mask protective structures under blast shock waves through numerical simulation. The study emphasizes the influence of the type and thickness of the protective structure on head injury. Our findings indicate that a helmet with a face shield can significantly slow down the propagation of the blast wave to the face, thereby reducing craniocerebral injury. Further analysis reveals that the combination of polycarbonate and aerogel layers is more effective than a fully polycarbonate face shield in mitigating intracranial pressure (ICP) in the frontal and parietal regions. Additionally, masks with 3-layer configurations (featuring a single 0.6 mm thick aerogel layer) and 5-layer configurations (with double 0.6 mm thick aerogel layers) performed best in preventing moderate and severe traumatic brain injury (TBI). These results provide a scientific basis and a new direction for the design and optimization of future protective helmets.

This research paper investigates the relationship between green packaging and brand image, focusing on their influence on consumer preferences and loyalty. In an era marked by increasing environmental consciousness, businesses are increasingly adopting sustainable practices, including the use of green packaging, to align with consumer values and enhance brand perception. Understanding how consumers perceive green packaging and its impact on their perceptions of a brand's image is crucial for companies seeking to establish competitive advantages in today's market. The study aims to address two primary objectives: first, to examine the relationship between consumer perceptions of green packaging and brand image, and second, to analyse the influence of green packaging and brand image on consumer loyalty towards the brand. These objectives are achieved through a comprehensive analysis of consumer preferences and behaviours related to sustainability and packaging. The research methodology involves the administration of a structured questionnaire to a diverse sample of consumers, capturing demographic information alongside perceptions of green packaging, brand image, and loyalty towards brands. The questionnaire items are designed to assess various dimensions, including the importance of environmentally friendly packaging in purchase decisions, perceptions of brand image attributes related to sustainability, and the likelihood of remaining loyal to brands that prioritize green packaging. Data collected through the questionnaire are subjected to rigorous regression and correlation analyses to uncover the underlying relationships between variables. Regression analysis elucidates how consumer perceptions of green packaging and brand image predict consumer loyalty, providing insights into the drivers of consumer behaviour in the context of sustainability. Correlation analysis further explores the strength and direction of associations between different variables, shedding light on the interconnectedness of consumer preferences and attitudes towards green packaging and brand image. The findings of this study contribute to both theoretical understanding and practical implications for businesses operating in environmentally conscious markets. By elucidating the significance of green packaging in shaping brand image and consumer loyalty, businesses can formulate effective strategies to leverage sustainability as a competitive advantage. Moreover, the study offers insights into consumer behaviour dynamics, highlighting the importance of aligning brand values with consumer preferences to foster long-term relationships and brand loyalty

Salak fruit is known to have many health benefits and is in great demand by the public. Fruits in Indonesia have a low shelf life, such as pondoh snake fruit. So, the temperature during the storage period of salak fruit needs to be considered. This research aims to determine the quality of pondoh salak fruit at different storage temperatures. This research was carried out at the Laboratory of the Faculty of Agriculture, Gunung Jati Swadaya University, Cirebon, West Java. The research was carried out in May – July 2024. The experimental design used was a Completely Randomized Design (CRD). This research consisted of 3 treatments and was repeated 9 times. The observation variables observed were weight loss, fruit hardness, sweetness, and vitamin C. The results showed that storage temperature significantly affected the weight loss and fruit hardness variables.

The phenomenon of mangoes being easily damaged due to high water content requires a preservation method to extend their shelf life without losing their nutritional qualities. The purpose of this study is to examine the effect of cold temperatures on the physical quality of mangoes, including taste, texture, color, and aroma. The study was conducted using a qualitative experimental method with organoleptic tests on four treatment groups: whole mangoes and slices at cold temperature (±4°C) and room temperature (±23°C). The assessment is carried out subjectively using a scale for each physical quality parameter. The findings of the study proved that storage at low temperatures for six days slowed down the decay and retained the texture of the mango but led to a decrease in sweetness, aroma intensity, and a paler color change. In contrast, storage at room temperature retains taste, color, and aroma better, although the texture is slightly coarse. Mango slices are more susceptible to damage than whole mangoes at both temperatures. This research provides recommendations for mango storage methods, namely room temperature to maintain the natural quality of the fruit in a short time and cold temperature as a temporary alternative to slow down damage.
