Princípios da Ética Ambiental e Mudanças Climáticas
Authors: Tonetto Milene 
Published: August 2024

O principal objetivo deste artigo é investigar quais princípios da ética do clima (a saber, os princípios poluidor-pagador, beneficiário-pagador, capacidade para pagar, igualdade de emissões per capita; princípios híbridos: princípio poluidor-pagador sensível à pobreza e capacidade para pagar sensível historicamente) podem ser usados na defesa de um modelo justo a ser desenvolvido para distribuir os deveres de mitigação das emissões, reparação e adaptação às mudanças climáticas. O artigo defende que um modelo justo de distribuição deverá reconhecer a contribuição histórica das emissões de gases de efeito estufa (GEE) para as mudanças climáticas, os beneficiários atuais das emissões de GEE, a capacidade de pagar os encargos e não impedir o desenvolvimento daqueles que pouco se beneficiaram com as emissões passadas.
PISA score as an inappropriate measure for growth? Empirical evidence from East Asia
Authors: Szécsi Dominika , Szunomár Ágnes 
Published: August 2024

AbstractThe topic of the research is whether better human capital, as determined by secondary school learning outcomes measured by PISA scores, promotes economic growth. The literature often uses the PISA results as a proxy for growth, while its use and impact on growth are not empirically proven. These questions are analyzed through two hypotheses. The first hypothesis (H1) states that in a worldwide sample of countries, GDP per capita growth between 2006 and 2019 was positively impacted by rising PISA results. The second hypothesis (H2) states that between 2006 and 2019, the rise in PISA scores in East Asia had a stronger influence on economic growth than in the rest of the world. The study examines 59 nations that have administered two PISA tests during the period of 2006–2019. The findings imply that there is generally no causal connection between PISA results and growth and the PISA results play no additional role in the development of East Asian nations. The results can be explained in two ways. The first is that human capital includes more than just skills. The second is that the data only covers a short period of time, which may limit the analysis of long-term patterns.

The object of the study is monetary processes and the real sector of the economy. The purpose of the study is to analyze the impact of monetary processes in the economy on GDP based on a systematic approach. The task of analyzing the relationship between the main indicators of monetary processes and GDP on the basis of a wide sample of countries was solved. The results are obtained:
– for the variables included in the cluster analysis, the money supply analyzed: (1st cluster “stable financial environment” – 0, 2nd cluster “high access to credit” – 147.7, 3rd cluster “limited access to credit” – 72.2, 4th cluster “high interest rates” – 30.4 % of GDP);
– 72 countries are divided into 4 clusters, with 13 countries in the first cluster, 15 in the second, 21 in the third, and 23 in the fourth. This allows to determine the nature and place of the economy in the world and to make monetary policy decisions;
– there is a positive correlation between GDP and money supply (r=0.317); there is a weak positive relationship between GDP and the credit information depth index (r=0.203); there is a moderate positive relationship between GDP and domestic lending (r=0.39). Money supply management and domestic credit should be prioritized in monetary management of the economy.
The obtained results are explained by the assumption of linear dependence between the indicators of monetary processes and the real sector of the economy. This assumption was confirmed on the example of different countries, which indicates its universality.
The peculiarities of the results obtained are the application of a combination of cluster and correlation and regression methods of analysis using actual World Bank data
Towards a sustainable supply chain: contribution to hospital waste management in an Algerian hospital

Published: August 2024

The object of research is medical waste management. Healthcare activities protect health, cure patients and save lives. However, they generate waste that is harmful to public health and the environment. As a result, the management of this healthcare waste is becoming increasingly important in the field of public health and the environment. One of the most problematic places is, poor management of these issues that can put healthcare workers, medical waste workers, patients and their families, and the entire population at risk. On the other hand, poor treatment or inadequate disposal of this waste can also cause risks. From now on, the rational elimination of this pollution is one of the essential conditions for respecting hygiene rules, not only inside establishments, but also in the general environment. In this unfavorable context, we are trying through this contribution to achieve adequate management using reverse logistics practices with the main objective of resolving healthcare waste management problems while taking into account the reality of things in situ. For this purpose, an approach guided by data, carried out directly in the field, by direct contact with the different categories of health personnel interviewed, through findings, observations, audits, questionnaire and knowledge of the causes was used. This approach is based on the audit of compliance with the supply chain in the management of hospital waste in the different departments of the Constantine University Hospital (Algeria). As a result of the research it is shown that the situation is very poor given that the logistics chain is completely faulty or no step is respected. Thus, the least respected stage is storage, where no service exceeds 25 %, this is due to the fact that no clinic has an intermediate waste storage area. And the most respected is treatment stage that does not exceed 75 %. This allowed to detect the inadequacies recorded at the level of the study establishment, and even improvements are suggested for sustainable management of healthcare waste at the level of Algerian health establishments.

Authors: Bilyi Ruslan 
Published: August 2024

The object of research is a bracelet that uses the electromyography (EMG) method to control a bionic prosthesis. In the conditions of the development of modern biomedical technologies and robotics, such a system becomes key to improving the quality of life of people with disabilities, providing efficient and accurate control of prostheses. The problem addressed in the research is the development and analysis of a bionic prosthesis control system using a bracelet using the EMG method. The main focus is on the optimization of data collection and processing processes, as well as the development of machine learning algorithms for gesture recognition in order to improve the accuracy and efficiency of prosthetic control.
The essence of the obtained results is the development and testing of a new bionic prosthesis control system that uses EMG signals obtained with the help of a bracelet. The study showed that the classifier based on the support vector method outperforms other algorithms such as neural networks and decision trees, achieving an average accuracy of 90 %. The obtained data were successfully filtered and subjected to feature extraction, which allowed to create effective gesture recognition algorithms. The system was tested in real time, which confirmed its high accuracy and efficiency.
The proposed system includes an innovative bracelet for collecting EMG data, which are then processed and analyzed using modern machine learning algorithms. The innovativeness of the proposed approach lies not only in the high accuracy of gesture recognition, but also in the possibility of adapting the system to different types of bionic prostheses and operating conditions. This is achieved by using a classifier based on the support vector method, which demonstrates significantly higher accuracy compared to other algorithms such as neural networks and decision trees. The test results show an average accuracy of 92.5 %, which confirms the high efficiency of the system.
The use of this system involves the intensive use of EMG sensors, which allows more accurate determination of the user's intentions regarding the control of the prosthesis. This, in turn, contributes to the improvement of the quality of life of users, providing them with greater functionality and convenience in the use of bionic prostheses.
Increasing the accuracy of oil recovery factor predictions by integrating lithology data
Authors: Martus Olena , Cvetkovic Branimir 
Published: August 2024

The object of research in the paper is the process of oil extraction during flooding. The Buckley-Leverett method, which is widely used to estimate oil production in flooding, has certain limitations that lead to uncertainty in the results. This paper proposes to extend the Buckley-Leverett algorithm by integrating lithological data. This approach allows to take into account the influence of geological characteristics of the formation on the process of displacement of oil by water, which leads to a significant increase in the accuracy of forecasting the oil production coefficient. The effectiveness of the proposed method is confirmed on the basis of data analysis of a real oil field.
The methodology for calculating the oil recovery coefficient during flooding using lithological dissection is presented. In this work, the steps of determining the oil recovery coefficient were analytically determined, which achieves a certain degree of accuracy due to the inclusion of the lithological characteristics of the permeable zone of the formation. The basic calculation of the lithological distribution over the layer was performed using the Kriging method. To confirm the accuracy of the Buckley-Leverett method, taking into account lithological dissection, the use of data analysis, including an experimental histogram and a theoretical normal distribution plot, is proposed. For data analysis, one hundred cases of lithological distribution were generated using the Sequential Indicator Simulation method.
The comparative analysis of the data of the experimental histogram and the theoretical graph of the normal distribution of the determination of oil recovery coefficients by the Buckley-Leverett method for cases with and without lithological dismemberment allows to quantitatively assess the accuracy of both studied options. On the basis of a real oil field, it is shown that the accuracy of oil recovery coefficients by the Buckley-Leverett method, taking into account lithological fragmentation, exceeds the similar method without taking into account lithological fragmentation by 11 %.

Published: August 2024

This study focuses on identifying the factors contributing to poor waste and sanitation management in slums, particularly emphasising the role of local assemblies in Ghana. Using a qualitative methodology, 21 individuals were selected from five different slum communities in Ghana to participate in the study. Results showed that a lack of knowledge among residents was a key factor contributing to the issue and that the local assemblies were not effectively enforcing waste and sanitation bylaws. Lack of knowledge of residents regarding the consequences of indiscriminate waste disposal is a major cause of waste and sanitation issues in slums. Additionally, the study highlighted the importance of stakeholder collaboration in addressing the problem. By promoting attitudinal change, enforcing bylaws and working with stakeholders, sustainable waste and sanitation management in slums can be achieved. The implication is that there is the need for the local assemblies to roll out targeted education and awareness programmes to inform the citizenry about the significance of effective waste management practices, the health implications about poor waste management and the impact of arbitrary waste disposal on the environment. This study provides valuable insight into waste and sanitation issues in developing countries, particularly from the perspective of policy implementers and end users.

Background. According to the World Health Organization, about 50 million people worldwide suffer from epilepsy. Almost 1/3 of patients are diagnosed with drug-resistant epilepsy (DRE). A relationship between intestinal microbiome (IM) and the central nervous system carried out throughout life via bidirectional dynamic network exists. It has been evidenced that IM profile becomes altered in patients with DRE.Objective: to summarize the current literature data on the role for microbiome-gut-brain axis in DRE, as well as to assess an importance of IM composition changes as a prognostic marker for developing DRE.Material and methods. The authors conducted a search for publications in the electronic databases PubMed/MEDLINE and eLibrary, as well as Google Scholar search engine. The evaluation of the articles was carried out in accordance with the PRISMA recommendations. Based on the search, 4,158 publications were retrieved from PubMed/MEDLINE database, 173 – from eLibrary, and 1,100 publications found with Google Scholar. After the selection procedure, 121 studies were included in the review.Results. The review provides convincing evidence about a correlation between IM and DRE demonstrating overt differences in IM composition found in patients with epilepsy related to drug sensitivity. IM dysbiosis can be corrected by exogenous interventions such as ketogenic diet, probiotic treatment and fecal microbiota transplantation subsequently resulting in altered brain neurochemical signaling and, therefore, alleviating epileptic activity.Conclusion. A ketogenic diet, probiotics and antibiotics may have some potential to affect epilepsy by correcting IM dysbiosis, but the current studies provide no proper level of evidence. Future clinical multicenter trials should use standardized protocols and a larger-scale patient sample to provide more reliable evidence. Moreover, further fundamental investigations are required to elucidate potential mechanisms and therapeutic targets.
Unveiling the Angular Momentum of Dark Matter Halos with Motion of Satellite Galaxies
Authors: Li Ran , Guo Qi , Gu Qing , Zhu Kai , Gao Liang , Shao Shi , Yang Hang , Yu Haoran 
Published: August 2024

Abstract

Dark matter halos are spun up by tidal torques originating from large-scale structures, resulting in an average spin parameter—a dimensionless measure of halo angular momentum—of approximately 0.04. Measurement of this angular momentum is crucial for validating the ΛCDM model and understanding the evolution of fundamental characteristics of the galaxy such as morphology and size. However, due to the invisible nature of dark matter, measuring the actual value angular momentum of dark halos is challenging. Here we report the first measurement for the value of angular momentum of dark matter haloes using a novel methodology. By stacking the orbital motions of satellite galaxies according to the projected rotation axes of their central galaxies, we calculate the projected orbital angular momentum of these satellites. This value is then converted into the intrinsic angular momentum of the dark matter halos using a conversion factor obtained from sophisticated hydrodynamical simulations. Applying this method to a selection of galaxy groups and clusters from the Sloan Digital Sky Survey (SDSS), we observe dark matter halo spins ranging between 0.0025 and 0.066 for halos with masses from [1012.5,1014] M⊙. These results are in excellent agreement with the predictions from the widely accepted ΛCDM model, thus substantiating a fundamental aspect of the theory of structure formation.

Abstract

Matrine serves as the molecular backbone, targeting the Hsp90 protein N-terminal domain (NTD) and C-terminal domain (CTD), both highly expressed in lung tumor cells. In this study, Matrine Contains Coumarins derivatives were designed and synthesized based on our previously reported compound C. Employing primary structure-activity relationships and docking analysis, a series of derivatives were biologically assessed for their antiproliferative effects against three cancer cell lines: A549, HepG-2, and HeLa cells. Based on the bioactivity results, derivative 5a emerged as the most potent, significantly enhancing antiproliferation against A549, HepG-2, and HeLa cells, with IC50 values of 7.35 ± 0.097, 7.727 ± 0.10, and 8.02 ± 0.065 µM, respectively. Subsequent mechanistic investigations confirmed 5a's ability to inhibit A549 cell proliferation and suppress colony formation and migration. In in vivo studies utilizing a xenograft mouse model inoculated with A549 cells in female Balb/c nude mice, compound 5a displayed superior antitumor activity compared to reference compounds 5-Fluorouracil and Matrine. Notably, the tumor growth inhibition (TGI) values for 5a, 5-Fluorouracil, and Matrine were 72.4%, 64.3%, and 46.8%, respectively.

Abstract

In this study, zinc oxide nanorods (ZnO NRs) were fabricated utilizing a straightforward sol-gel process at ambient temperature. They were then used as photoanode material in the production of a sandwich-type sensitized solar cell device. Scanning electron microscopy was utilized in order to investigate the morphologies and average particle sizes, respectively. After the preparation of a binder-free ZnO NRs thin film, CdS quantum dots (QDs) were subsequently incorporated into the material. ZnO NRs with modified CdS QDs have distinct structural and optoelectronic properties than ZnO NRs without the CdS QD modification. With the use of the N719 dye, a modified ZnO NRs-CdS QDs photoanode was sensitized. An optical investigation showed that the sensitization of CdS QDs on to ZnO NRs led to a red-shift in the material. At the same time, the absorbed N719 dye molecule further boosts the visible light, which can significantly increase the overall efficiency of a solar device. It was found that the solar cell performance of the one and alone N719-sensitized ZnO NRs device (ZnO-N719) was significantly lower than that of a CdS QDs-modified ZnO-N719 device. Solar cell properties were improved by using a hybrid (ZnO-CdS QDs -N719 dye) solar cell operating at 100 mW/cm2 AM 1.5G.

Abstract

In the mangrove of Guinea, where the most active foci of Human African Trypanosomiasis in West Africa are located, vector control against tsetse flies using insecticide impregnated tiny targets was first introduced in 2012. While annual deployments of Tiny Targets have resulted in an overall 90% reduction in tsetse fly densities in control areas, managing tsetse densities in specific biotopes like mangrove channels, which are susceptible to significant climatic disturbances, presents greater challenges. Thus, a new three-dimensional model called the Cross Target was designed to address this situation. In a first phase, we evaluated the attractiveness of the Cross Target along with three other devices (the Tiny Target, the biconical trap and the pyramidal trap) in a latin square design. In a second phase, we assessed the efficacy of the Tiny Target and the Cross Target to control tsetse densities in a pilot field study led in two adjacent mangrove channels. In the latin square study, the Cross Target was significantly more attractive than the other devices with catch index of 1.6 (p = 0.03); 2.2 (p = 0.004) and 2.4 (p = 0.003) as compared to the biconical trap, the Tiny Target and the pyramidal trap respectively. In the pilot experimental field evaluation, the Cross Target also showed its superiority with tsetse densities reduction reaching 90% fifteen months after the initial deployment whereas densities remained high in the channel where Tiny Targets were deployed. This study underscores the superiority of the new three-dimensional Cross Target in terms of attractiveness to tsetse flies and its resilience to climatic disturbances as compared to the conventional Tiny Target. The Cross Target presents a promising solution to enhance vector control effectiveness in challenging environments such as mangroves or other hard-to-access areas where target maintenance is particularly difficult.
Fracturing as a sample preparation method of basalt for SEM analysis
Authors: Gembitskaya I. , Vasilev E. , Kalina V. , Nagornov O. 
Published: August 2024

Abstract

The article discusses a method for preparing basalts for HR-SEM analysis. This method involves fracturing samples under identical conditions using an Izod pendulum. Fractures propagate in a sample mainly along the grain boundaries; its cross pores and mineral inclusions, which are stress concentrators. That is why submicron mineral gains are revealed on fracture surfaces rather than on polished surfaces. Surfaces of fresh fracture were studied in basalt samples from the Etna vents and Tolbachik fissure zone. Crystals with zinc, copper, nickel, sulfur, and iron were found on surfaces of fresh fracture. The morphology was revealed of submicron crystals of apatite, orthopyroxene, spinel, and copper sulfide. These crystals have not been found on polished thin sections of the specimens, since they were not brought to the surface or were chipped out. The morphology of submicron inclusions in orthopyroxene and olivine were shown. The fracture surface, in contrast to the thin section surface, retains more information on zoning in rock-forming minerals. Features of the accessory minerals distribution, the morphology of crystals in pores, and the compound of minerals inside inclusions are presented more reliably on the fracture surface. The authors propose to introduce the fracture surface study into petrogenetic research.
