The role of the municipalities in achieving the EU’s sustainable energy transition
Authors: Takácsné Papp Adrienn
Published: December 2023

Greenhouse gas emissions are clearly responsible for the intensification of climate change, the largest share of which can be attributed to energy production and use. The European Union aims to reduce its greenhouse gas emissions to net zero by 2050. This energy transition by 2050 is called the energy transition. One of the European Union's best-known energy and climate organisations is the Covenant of Mayors for Climate and Energy (CoM). This publication evaluates the role of municipalities in the energy transition with the help of the analysis of the Sustainable Energy and Climate Action Plans (SECAP) document prepared by the Hungarian municipalities joining the alliance, especially from 16 submitted cities point of view. When planning the area-by-area reductions formulated in their mitigation action plans, they realistically perceive the extent of their direct intervention opportunities, they expect a greater proportion of the planned measures from local actors, so they can help achieve the goals by their exemplary operation, organizing awareness-raising events and finding sources of funding. Through their indirect role in local energy management, municipalities are important actors in achieving the EU's energy transition.

Published: December 2023

In the online realm, pricing transparency is crucial in influencing consumer decisions and driving online purchases. While dynamic pricing is not a novel concept and is widely employed to boost sales and profit margins, its significance for online retailers is substantial. The current study is an outcome of an ongoing project that aims to construct a comprehensive framework and deploy effective techniques, leveraging robust machine learning algorithms. The objective is to optimize the pricing strategy on e-commerce platforms, emphasizing the importance of selecting the right purchase price rather than merely offering the cheapest option. Although the study primarily targets inventory-led e-commerce companies, the model's applicability can be extended to online marketplaces that operate without maintaining inventories. The study endeavors to forecast purchase decisions based on adaptive or dynamic pricing strategies for individual products by integrating statistical and machine learning models. Various data sources capturing visit attributes, visitor details, purchase history, web data, and contextual insights form the robust foundation for this framework. Notably, the study specifically emphasizes predicting purchases within customer segments rather than focusing on individual buyers. The logical progression of this research involves the personalization of adaptive pricing and purchase prediction, with future extensions planned once the outcomes of the current study are presented. The solution landscape for this study encompasses web mining, big data technologies, and the implementation of machine learning algorithms.

Authors: Zakordonets Volodymyr , Movchan Leonid , Hetmaniuk Volodymyr
Published: December 2023

Using the method of electrothermal analogy, a mathematical model of the thermal stabilization system of the LED matrix with a heat pipe was developed. The system of differential equations is solved, including the stationary equation of heat conduction and the equation of heat generation, which are supplemented by boundary conditions of conjugation for heat fluxes and temperatures. The calculated temperature distribution in the structural elements of the thermal stabilization system depending on the power of the LED matrix, heat pipe parameters and the temperature of the environment. It is shown that the use of the proposed thermal stabilization system will allow to increase the luminous flux of the LED-matrix (increase the light power) without increasing the temperature of its active zone. This will allow to reduce the number of LED-matrix in the semiconductor lamp and its cost without shortening the service life.

Introduction: It is well established that in the long-term, many stroke patients potentially have relevant functional incapacity related to deficits in domains other than motor; the burden of unmet long-term needs likely varies between different types of stroke or different healthcare systems. On the other hand, we can say that the ideal length of follow-up in a specialized consultation after ischemic stroke has not been established. Methods: We evaluated long-term stroke patients who underwent endovascular treatment of anterior circulation in our stroke center and that were classified as “therapeutic success” (modified Rankin scale - mRS <3) at 3 months, to participate in an observational, cross-sectional study. Participants underwent a comprehensive interview and examination using validated standard questionnaires for Portuguese population to assess different life aspects after stroke as Post-Stroke Checklist, EQ-5D-3L scale, mRS, Barthel Index (BI), Burden Scale for Family Caregivers and Hamilton scale. Results: We evaluated 36 patients. The mean age was 67.6 years old (±13,8) and the mean time for the interview was 52,8 (±9,9) months after the stroke. Most patients were independent, with a mean mRS of 1 (ranging from 0–3) and BI 95,4 (70-100). Sixty one percent had a clinically significant deficit in at least one domain. On the Post Stroke Checklist (PSC), 77,8% of participants demonstrated a not good perceived health status. EuroQoL index value was 0.750 (IQR 0.664–1.00). The two major disability parameters identified were in cognition (52,8%) and depression (27,8%). After review of the ongoing care by stroke specialists, in almost 2/3 of the patients, additional measures were proposed: additional etiological investigation (44%), physical or speech rehabilitation (~14%) or changes in pharmacological therapy (~3%). Conclusion: These results highlight the prevalence and importance of non-motor disabilities in long-term stroke patients, even after short-term classification as “therapeutic success”. We also point out that even after more than 3 years of the stroke, additional therapeutic or etiological investigation measures were taken, reinforcing the need for individualized follow-up, without a pre-defined maximum follow-up time in a specialized cerebrovascular pathology consultation.
Image Processing and Traditional Machine Learning Based Classification of Brown Marmorated Stink Bug (Halyomorpha Halys) Defected Hazelnut
Authors: GADALLA Omsalma Alsadig Adam , ÖZTEKİN Y. Benal
Published: December 2023

Quality control of hazelnuts is a major concern in many regions across the world, but particularly in Turkey as the world's largest hazelnut producer. Using image processing and deep learning techniques, this study intended to detect and classify healthy hazelnuts and hazelnuts infected with the Brown Marmorated Stink Bug. Infected hazelnut samples were collected from the 2021 production period by experts. A Guppy Pro CCD camera-based image acquisition system was used to capture hazelnut images. A total of 400 RGB hazelnut images were captured to train machine learning models. Image segmentation process was carried out to subtract hazelnut images from the background using the Thresholding technique. Moment features were extracted from RGB and l*a*b* spaces to be used to train traditional machine learning models. Furthermore, the most relevant and discriminative feature set was selected using the Boruta feature selection method. Traditional machine learning models including Random Forest, Support Vector Machine, Logistic Regression, Naive Bayes, and Decision Tree were trained twice, once with all features and another with the selected feature set only. The overall accuracy, statistical characteristics of the confusion matrix, and model training time were all calculated to evaluate and compare models performances. As a result, threshold value of 50 was determined from the gray level histogram and was able to separate hazelnut image from the background perfectly. Only seven moment features were identified as the most discriminative features out of 24 features. The SVM model with all feature vectors had the greatest classification accuracy of 98.75 %. When only the selected features were employed, the performance of Random Forest and Logistic Regression models improved to 97.5 and 96.25 %, respectively.
Molecular barcoding reveals patterns of egg predation in small pelagic fish
Authors: Veríssimo A , Fonseca P , Garrido S
Published: December 2023

Cannibalism and intraguild predation occur in a vast number of small pelagic fish (SPF) species. Egg and larval predation can have important consequences on mortality, and its accurate assessment is important to estimate the impact on recruitment strength and population dynamics of predators and prey. Such assessments are hampered by limitations in visual species identification of many fish eggs and larvae in the predators’ stomachs. European sardine Sardina pilchardus and Atlantic chub mackerel Scomber colias, the dominant species of the pelagic food web off the Canary Current Upwelling ecosystem, are major predators of fish eggs. Egg predation by these SPF species is particularly high on sardine and anchovy eggs, but many preyed fish eggs are not amenable to visual identification. This study provides a proof-of-concept application of molecular identification of diverse fish eggs from SPF stomach contents not suitable for visual identification, as a way to improve our understanding of the impact of intraguild predation on fish population dynamics. Results show a high diversity of fish species in the eggs ingested by sardines and chub mackerel (18 and 15 families, respectively), mostly comprising locally abundant coastal taxa. Sardine ingested predominantly anchovy, sardine and sparid eggs, while chub mackerel ingested predominantly sparid eggs, followed by serranid (Serranus spp.) and sardine eggs. Sardines also showed higher variability in prey composition compared to chub mackerel. Exploratory analyses also suggested variability in prey composition with sampling area, season and maturity stage for sardine and chub mackerel, highlighting the need for dedicated follow-up studies.

Published: December 2023

The article presents an analysis of the results of a survey of 105 children with pulmonary echinococcosis aged 4 to 16 years who received inpatient treatment in the thoracic surgical department of the Osh Interregional Children's Clinical Hospital. The aim of the study was to study the immune status of patients suffering from lung echinococcosis. The research method was a complex immunogram, which determines the state of humoral immunity. It was revealed that the organism of a child reacts to the invasion of the parasite in the form of chronic intoxication, which manifests itself in the form of a lack of body weight, lag in physical development, adynamia, hypochromic anemia, dysproteinemia, etc. In addition, in children with combined echinococcosis, the level of total IgE is more than 4 times higher than in patients with other forms of echinococcosis of the lungs, but at the same time, without changing the number of poorly differentiated forms of T cells and their precursors. This is explained by the fact that in the body of children suffering from a combined form of echinococcosis, the immune system undergoes tremendous changes and requires special attention by the attending physician through an in-depth examination in the pre- and postoperative periods and the study of long-term results.

Pandemia y derechos humanos: asegurando la igualdad en el orden internacional
Authors: Díaz Galán Elena Carolina
Published: December 2023

El presente trabajo tiene como objetivo establecer el vínculo entre la pandemia de la Covid-19 y la labor de la comunidad internacional en defensa de los derechos sociales y la protección de grupos que están en situación de vulnerabilidad. Estos dos ámbitos son preferentes respecto a las consecuencias de la crisis sanitaria, en perspectiva de derechos humanos en el sistema internacional. Para garantizar la igualdad en la sociedad internacional será preciso prestar atención a los derechos sociales en tiempos de pandemia, particularmente, el derecho a la salud y otros como el acceso al trabajo o la educación. Pero, también, será necesario proteger a los grupos en situación de vulnerabilidad como los niños, personas privadas de libertad, personas de edad o personas con discapacidad. Estos grupos, y muchos más, deben disponer de mecanismos de protección por la pandemia que les castiga con mayor virulencia y porque hay que ajustar las medidas para combatirla sin que se limiten derechos fundamentales.
Effect of gamma irradiation on morphology and local elemental composition of basalt-based composite material

Published: December 2023

Scanning electron microscopy (SEM) was used to examine the polished surface of samples made of basalt-based composite material before and after gamma irradiation. Morphology and local elemental composition changes in binder, filler and boundary of composite components depending on radiation dose were revealed. The samples were irradiated within a dose range of 5 to 15 Mrad. It has been shown that at radiation doses up to 10 Mrad, new intermolecular bonds are formed and the material is strengthened. With large doses of radiation, the destruction of bonds and the formation of a gas phase is observed. This results in softening of the composite. A sufficiently large amount of nitrogen has been detected in the highly irradiated binder. A possible mechanism has been proposed to explain this phenomenon.

The purpose of the study is to investigate the impact Russian Federation and the Republic of Uzbekistan’s demographic trends on the development of national healthcare systems. We studied official data from the websites of the World Health Organization, the Statistical Committee of the Union of Independent States, and the State Statistics Service of Russia and Uzbekistan for 10 years. Using analytical, statistical research methods and the SPSS program, the reliability of the differences in the obtained data was assessed at t>2 and p<0.05. Demographic characteristics Russia and Uzbekistan are population indicators of the health status and national health care systems indicators of the effectiveness. Monitoring of morbidity, mortality and disability indicators in Russia and the Republic of Uzbekistan revealed both similarities and differences in the levels of epidemiological indicators, which is due to different types of age structure of the population in these countries (regressive and progressive, respectively). In order to reduce the economic burden of disease within the framework of intersectoral cooperation and at the level of health systems within the framework of primary health care, it is necessary to conduct epidemiological studies, including systematic analysis of morbidity, disability and mortality rates, which predetermines the development of international scientific cooperation in order to improve and implement strategic directions development of healthcare systems.
Gender Differences in Perception of Artificial Intelligence-Based Tools
Authors: Ofosu-Ampong Kingsley
Published: December 2023

Participation of girls in Science, Technology, Engineering, and Mathematics (STEM) subjects at the higher education (HE) level continues to lag behind that of boys and consequently may affect artificial intelligence proliferation in Ghana. Numerous factors affect girls' engagement in science, one of which is the mistaken belief among girls that STEM subjects are better suited for boys. This study investigates the gender differences in AI-based tools which have become integral for teaching and learning in HE schools. Based on results from 128 students in higher education in Ghana, this article argues that gender is a significant determinant of students’ use of AI-based tools in education. The results further revealed a significant disparity in the overall levels of perceived innovation characteristics based on gender. This study urges managers of Higher Education Institutions (HEIs) to implement policies and measures aimed at facilitating women's engagement and greater familiarity with AI technologies.
Experiência abstrata da arquitetura na síndrome de hipervisibilidade do observador
Authors: Rahim Shakil
Published: December 2023

O consumo da arquitetura e do património desencadeado pela promoção do marketing e pressão turística das cidades, tem transformado os centros históricos e desvirtuado a identidade, a experiência e fruição dos lugares edificados. A homogeneização cultural e a urgência social da condição pós-moderna criou um observador frenético e hiperativo, num estado de sobressalto e exaustão, em permanente exposição e excesso de informação. A este estado chamamos síndrome de hipervisibilidade. Condição de mal-estar que afeta as funções cognitivas, reduz a disponibilidade mental e aumenta a ansiedade, com sintomas de desorientação, desrealização, frustração, melancolia, dispersão visual, desatenção dividida, e súbito interesse por Arte. Contrária à síndrome de Stendhal, na síndrome de hipervisibilidade do observador não há alteração psicossomática pela qualidade e valor da obra artística; a alteração deriva da sobrecarga atencional do excesso de luz e transparência, que na urgência de “ver tudo” desencadeia uma hipovisualidade que reduz a espessura e a textura da arquitetura, tornando-a lisa, positiva, plana e uniforme. A abstração da experiência planificada separa os sentidos do corpo, com dissociação cognitiva dos elementos arquitetónicos e da composição atmosférica, num evidente desajuste entre tempo real e espaço ficcionado. Emerge a fobia ao aborrecimento num desassossego de contínua falta de tempo, justificado pela busca da “experiência do inesquecível”. A abstração espacial pode ter como metáfora os postais ilustrados de modelos 3D planificados em miniatura, que reproduzem recortes de fachadas e invólucros vazios, num fetiche de verossimilhança que elimina o volume, a sombra e a profundidade. O exemplo das cidades italianas, como Roma, Florença e Veneza, permite intersetar a perfusão de obras de excecional valor arquitetónico e cultural com a composição de percursos patrimoniais, a identidade do lugar e a experiência individual da hipervisibilidade do observador na multidão.

Bioreactors have been employed in tissue engineering to sustain longer and larger cell cultures, managing nutrient transfer and waste removal. Multiple designs have been developed, integrating sensor and stimulation technologies to improve cellular responses, such as proliferation and differentiation. The variability in bioreactor design, stimulation protocols, and cell culture conditions hampered comparison and replicability, possibly hiding biological evidence. This work proposes an open-source 3D printable design for a perfusion bioreactor and a numerical model-driven protocol development strategy for improved cell culture control. This bioreactor can simultaneously deliver capacitive-coupled electric field and fluid-induced shear stress stimulation, both stimulation systems were validated experimentally and in agreement with numerical predictions. A preliminary in vitro validation confirmed the suitability of the developed bioreactor to sustain viable cell cultures. The outputs from this strategy, physical and virtual, are openly available and can be used to improve comparison, replicability, and control in tissue engineering applications.
