Is а Multipolar World Possible аfter February 24 аnd is There a Place for the EU in It?
Authors: Dimitrova Ani
Published: August 2023

The present article focuses on the question is a multipolar world possible after 24 February 2022 and what is the place of the EU in this world. The system of international relations established after the Second World War is undergoing its most serious revision with the beginning of Russia’s military actions against Ukraine. The declarative political requests of Russia, China and the countries around them after 24 February 2022 were transformed into real actions, including military ones, which show the ambition and capabilities of these countries to cause discussion about and effect changes in the existing system of international relations. The EU faces serious challenge – will it be able to assert its role as a political pole in a multipolar world. This role implies that the EU consolidates, reforms and extends the scope of the multilateral approach through which it operates to new areas, so that it can help Europeans realize their interests on the global stage and contribute to a more stable multipolar order, maintaining its openness by adherence to cooperation and accepted rules. Therefore, the EU must become a political union with common economic visions and procedures, which will determine whether the EU is part of the forming poles or will have an independent weight. At the same time, the question arises of whether we are ready for a multipolar currency world. The analysis leads to the following conclusions: 1) a multipolar world is possible; 2) the challenge is that the process of forming multipolarity in international relations does not lead to antagonism and fragmentation, but to strengthening the processes of unification and integration; 3) the world is changing rapidly and humanity is entering a new era of deep transformation, which also includes the presence of multipolarity, economic globalization, development of information society, cultural diversity, transformation of the architecture of global governance and world order, as well as increasing interconnectedness and interdependence between countries.
The EU Foreign Policy in Central Asia: Structural and Relational Dimensions
Authors: Velichkov Kamen
Published: August 2023

The EU foreign policy in Central Asia pursues both structural and relational objectives. In contrast to the 1990s, the EU no longer prioritizes the transition and modernization of countries from the region but focuses on their resilience. Compared to the policies of China, Russia, or the US, the EU exerts a more limited influence on its partner countries that varies across domains and issue areas. While the Union is losing the structural power competition in this region, it nevertheless maintains its ambition to be and act as a pole of the international system.
The EU conducts its dialogue and cooperation with the Central Asian states mainly in a multilateral “region-to-region” format. At the same time the Union adopts differentiated approaches towards individual countries. Many observers assert that as an international actor, the EU is more trusted than other major powers in Central Asia. It aims to support the independent development of the sovereign Central Asian countries, contributing significantly to the emergence of some degree of regionalization in this part of the world. It is on this perceived benevolence that the EU can capitalize.

Published: August 2023

Background: Infiltration between the popliteal artery and capsule of the knee (iPACK) is one method that has been proposed in recent years as a potential alternative to peripheral nerve block as analgesia in total knee replacement (TKR) procedures. This study presents anesthetic management using spinal anesthesia combined with iPACK and adductor canal block (ACB) in patients with grade IV osteoarthritis who underwent TKR of the right knee.

Case presentation: A woman, a housewife aged 50 years, was planning to undergo TKR surgery. The patient came with complaints of pain in the right knee 1 year before entering the hospital. The patient was given supplemental oxygen with a nasal cannula at 3 liters per minute. Prior to spinal anesthesia, the patient was given fentanyl 25 mcg iv, ketamine 10 mg iv, and midazolam 1.5 mg IV as premedication. The patient was positioned on the right side, and a 27G Quincke needle was inserted at the level of L3-L4 and given bupivacaine heavy 0.5% 7.5 mg, then lateralized for 15 minutes. After lateralization, the patient was positioned supine and used ultrasound to direct ACB action with a regimen of ropivacaine 0.25% + dexamethasone 5 mg a volume of 20 ml, then iPACK was performed with a regimen of Ropivacaine 0.375% + dexamethasone 5 mg a volume of 20 ml. After surgery, the patient is treated in the recovery room for 1 hour until bromage score is 0. The patient received the PCA Morphine analgesic demand only 1 mg/mL, 1 mg per dose, max 5 mg over 4 hours, lockout interval 6 minutes; Paracetamol 500 mg every 6 hours PO; Ibuprofen 400 mg every 8 hours PO.

Conclusion: TKR patients who were given analgesia using the ACB peripheral nerve block technique combined with iPACK experienced a decrease in pain levels and lower use of postoperative morphine so that patient mobilization was faster and reduced the patient's length of stay.

Published: August 2023

E-tendering plays a key role in ensuring that the best suppliers are selected for a continuous supply of better-quality products and services. The study focused on the role of e-tendering through online registration of suppliers, virtual screening, automatic evaluation and automated supplier selection criteria- through the use of an electronic Decision Support System (e-DSS). The study adopted the null hypothesis that e- tendering had no statistically significant influence on parastatals in Nakuru County. The study population included five (5) selected state-owned organisations in Nakuru municipality with a total population of 236 employees in selected departments where a sample size of 91 employees was drawn by application of Daniel’s (1999) sample size formula. Structured questionnaires were used as the main instrument to collect data, out of which 80 respondents gave their responses, an 87.9% response rate. The regression analysis showed a 4.6% change in organisational performance was described by e-tendering. The study confirmed there was a statistical significance (p=.000) between e-tendering and organisation performance, where e-tendering, as a supplier management tool, was able to account for a positive marginal significant increase (B=.133) in organisational performance. There was a moderate positive correlation between organisational performance and e-tendering at .519. The study recommends that parastatals enhance system integration for compatibility and easy access and flow of information, leverage technology, and facilitate training and educating their suppliers on how to use the organisation’s systems and other ICT-related functions.

Revisión bibliográfica sobre el manejo actual de plastrón apendicular
Authors: Rivera Diaz Johnny Fernando , Loaiza Merino Iván Patricio
Published: August 2023

Introducción: La apendicitis aguda sin tratamiento oportuno puede evolucionar hacia una perforación apendicular causando entidades de mayor gravedad como la peritonitis localizada o sepsis generalizada, sin embargo, en otros casos menos comunes el organismo controla parcialmente este proceso generando un plastrón apendicular, constituido por tejidos adyacentes y delimitando el proceso infeccioso. Objetivo: Describir el adecuado diagnóstico y las principales complicaciones que se pueden desarrollar en pacientes con plastrón apendicular y determinar así la modalidad de tratamiento más adecuada para esta patología. Métodos: Se realizó una revisión bibliográfica de la literatura científica a través de artículos en idioma inglés y español, desde el 2017 al 2023 centrándose en el diagnóstico, complicaciones y modalidad de tratamiento para el plastrón apendicular. La búsqueda se realizó en múltiples bases de datos como: Pubmed, Science Direct, Medigraphic, Cochrane, Medline, ElSevier, Google Scholar, Scielo y New England Journal of Medicine.  Resultados y discusión: Entre las modalidades de tratamiento para el plastrón apendicular se encuentran la intervención quirúrgica inmediata o un manejo conservador, con posibilidad de realizar una apendicectomía diferida cuando se estabiliza el cuadro agudo. Sin embargo, actualmente existen estudios que justifican cada modalidad de tratamiento, basándose en la duración de la estancia hospitalaria, el riesgo de recurrencia, las posibles complicaciones, el costo económico y la adecuada reincorporación a labores diarias.  Conclusión: El cuadro clínico y los métodos diagnósticos son similares a la presentación clásica de la apendicitis aguda. Sin embargo, al examen físico es habitual palpar una masa a nivel de fosa iliaca derecha, que puede ser confirmado por ecografía o tomografía computarizada, con posibilidad de formación del absceso apendicular como principal complicación. No obstante, la modalidad de tratamiento sigue siendo tema de debate por lo que es importante realizar nuevos estudios a futuro.

Published: August 2023

In this study, we had developed a method of ultrasound assisted extraction from Elecampane in order to obtain, identify and the dosing the main bioactive compounds from plant, such as: alantolactone and isoalantolactone, inulin etc. Aqueous/hydroalcoholic extraction assisted by ultrasound, was used in order to obtain plant extracts rich in bioactive compounds, in order to ensure the highest possible extraction yield (exhausting the plant). In the process of extracting bioactive compounds from plant, the acoustic energy of the ultrasound is not absorbed by the molecules and, as such, has an effect of breaking the cell walls and improving the mass transfer. Ultrasound are transmitted in the reaction medium in the form of pressure waves that induce vibrational movements of the molecules, thus the molecular structure of the medium, alternately, it compresses and expands, as a result of a pressure, that varies over time. When the ultrasound intensity is high enough, the expansion cycle can create bubbles or cavities. Cavitation is the process by which bubbles form, grow and undergo implosion. Ultrasound allows the solvent to penetrate the cell walls, and the bubbles produced by the acoustic cavitation favor the breaking of the cell wall and the release of the active compounds, increasing the reaction yield. A high content from these compounds, make the plant to be used in the treatment of different respiratory diseases (asthma, cold, flu), indigestion, intestinal parasites etc. Recent studies had shown that the extracts from dried root of Elecampane have antitumor and antimicrobial effect and also detox and anti-inflammatory action.
COMPARISON OF DIFFERENT ADSORBENTS, CELLULOSE AEROGEL, DEVULCANIZED RUBBER GRANULES AND PYROLYZED SEWAGE SLUDGE GRANULES, FOR DYE REMOVAL FROM CONTAMINATED WATER
Authors: Liugė Monika , Paliulis Dainius
Published: August 2023

The release of dyes used in the textile industry into the natural environment causes unwanted negative effects due to the carcinogenic, mutagenic or even teratogenic properties of the dyes. Based on their chemical composition, dyes are divided into anionic, cationic and non-ionic dyes. In this work, the physical method of wastewater treatment – adsorption – was studied. This is a method in which various natural substances called sorbents are used. Materials used in the adsorption process should be nontoxic, environmentally friendly, cheap, and their use should not cause secondary pollution. The idea of using sorbents made from waste in experimental studies, which can even be used several times in the adsorption process, promotes the sustainable use of resources. The study compared different sorbents: aerogel, devulcanized rubber granules and sewage sludge. It was found that the highest values of adsorption efficiency were characterized by sewage sludge granules that were pyrolyzed at 500 °C. Using 500 °C pyrolysis sewage sludge, the adsorption efficiency reached 28.14–53.73%. Granules made from devulcanized car tire rubber had the lowest adsorption efficiency values: the adsorption efficiency value reached 12.92%. The adsorption efficiency values of the aerogel synthesized from paper waste ranged from 28.21 to 38.07%.
Testing the Collisionless Nature of Dark Matter with the Radial Acceleration Relation in Galaxy Clusters
Authors: Tam Sut-Ieng , Umetsu Keiichi , Robertson Andrew , McCarthy Ian G.
Published: August 2023

The radial acceleration relation (RAR) represents a tight empirical relation between the inferred total and baryonic centripetal accelerations, g
tot = GM
tot(< r)/r
2 and g
bar = GM
bar(< r)/r
2, observed in galaxies and galaxy clusters. The tight correlation between these two quantities can provide insight into the nature of dark matter. Here we use BAHAMAS, a state-of-the-art suite of cosmological hydrodynamical simulations, to characterize the RAR in cluster-scale halos for both cold and collisionless dark matter (CDM) and self-interacting dark matter (SIDM) models. SIDM halos generally have reduced central dark matter densities, which reduces the total acceleration in the central region when compared with CDM. We compare the RARs in galaxy clusters simulated with different dark matter models to the RAR inferred from CLASH observations. Our comparison shows that the cluster-scale RAR in the CDM model provides an excellent match to the CLASH RAR obtained by Tian et al. including the high-acceleration regime probed by the brightest cluster galaxies (BCGs). By contrast, models with a larger SIDM cross section yield increasingly poorer matches to the CLASH RAR. Excluding the BCG regions results in a weaker but still competitive constraint on the SIDM cross section. Using the RAR data outside the central r < 100 kpc region, an SIDM model with σ/m = 0.3 cm2 g−1 is disfavored at the 3.8σ level with respect to the CDM model. This study demonstrates the power of the cluster-scale RAR for testing the collisionless nature of dark matter.

Hycean worlds are a proposed subset of sub-Neptune exoplanets with substantial water inventories, liquid surface oceans, and extended hydrogen-dominated atmospheres favorable for habitability. We aim to quantitatively define the inner edge of the Hycean habitable zone (HZ) using a 1D radiative-convective model. As a limiting case, we model a dry hydrogen–helium envelope above a surface ocean. For a 1 bar (10,100 bar) atmosphere, the hydrogen greenhouse effect alone sets the inner edge of the HZ at 0.216 au (0.58, 3.71 au) for a Sun-like G star and at 0.0364 au (0.110, 0.774 au) for an 3500 K M star. Introducing water vapor into the atmosphere, the runaway greenhouse instellation limit is greatly reduced due to the presence of superadiabatic layers where convection is inhibited. This moves the inner edge of the HZ from ≈1 au for a G star to 1.6 au (3.85 au) for a Hycean world with a H2–He inventory of 1 bar (10 bar). For an M star, the inner edge is equivalently moved from 0.17–0.28 au (0.54 au). Our results suggest that most of the current Hycean world observational targets are not likely to sustain a liquid water ocean. We present an analytical framework for interpreting our results, finding that the maximum possible outgoing longwave radiation scales approximately inversely with the dry mass inventory of the atmosphere. We discuss the possible limitations of our 1D modeling and recommend the use of 3D convection-resolving models to explore the robustness of superadiabatic layers.
On the Proposed Interstellar Origin of the USG 20140108 Fireball
Authors: Brown Peter G. , Borovička Jiří
Published: August 2023

A critical review of the evidence for the interstellar origin of the USG 20140108 fireball is presented. Examining United States Government (USG) fireball velocities where independent data are available shows the former to have significant (10–15 km s−1) uncertainties at large speeds and highly variable radiant accuracy, with average errors in excess of 10°. The ablation model fits to the observed lightcurve are possible for normal chondritic impactors only assuming low speeds. To match the high speed and low fragmentation height of the USG 20140108 fireball would require a high-density/strength object with low drag and a highly aerodynamic shape not made of iron. We suggest the simplest explanation for the unusual characteristics of USG 20140108 is that the speed, in particular, is substantially overestimated.
Sample Variance in Cosmological Observations with a Narrow Field of View
Authors: Espenshade Peter , Yoo Jaiyul
Published: August 2023

Surveys with a narrow field of view can play an important role in probing cosmology, but inferences from these surveys suffer from large sample variance, arising from random fluctuations around the cosmic mean. The standard method for computing the sample variance is based on two key approximations: treating perturbations linearly and the survey geometry as a box. We demonstrate that it can lead to a significant underestimate of the sample variance in narrow surveys. We present a new method for accurately computing the sample variance and apply our method to the recent observations of the warm–hot intergalactic medium (WHIM) based on spectroscopic measurements of blazars. We find that the sample variances in these surveys are significantly larger than the quoted measurement errors; for example, the cosmic mean baryon density contained in the WHIM could be lower by 54% at 1σ fluctuation than estimated in one observation. Accurately quantifying the sample variance is essential in deriving correct interpretations of the measurements in surveys with a small field of view.
Stability of stochastic dynamic systems of a random structure with Markov switching in the presence of concentration points

Published: August 2023

This article aims to investigate sufficient conditions for the stability of the trivial solution of stochastic differential equations with a random structure, particularly in contexts involving the presence of concentration points. The proof of asymptotic stability leverages the use of Lyapunov functions, supplemented by additional constraints on the magnitudes of jumps and jump times, as well as the Markov property of the system solutions. The findings are elucidated with an example, demonstrating both stable and unstable conditions of the system. The novelty of this work is in the consideration of jump concentration points, which are not considered in classical works. The assumption of the existence of concentration points leads to additional constraints on jumps, jump times and relations between them.
Free boundary problem for a nonlocal time-periodic diffusive competition model
Authors: Chen Qiaoling , Li Fengquan , Tang Sanyi , Wang Feng
Published: August 2023

In this paper we consider a free boundary problem for a nonlocal time-periodic competition model. One species is assumed to adopt nonlocal dispersal, and the other one adopts mixed dispersal, which is a combination of both random dispersal and nonlocal dispersal. We first prove the global well-posedness of solutions to the free boundary problem with more general growth functions, and then discuss the spreading and vanishing phenomena. Moreover, under the weak competition condition, we study the long-time behaviors of solutions for the spreading case.
Project-Based Learning as a Tool to Meet Learning Results: A Case Study of Teaching Microcontrollers

Published: August 2023

This article presents a proposal of project-based learning (PBL) as a didactic tool to meet the learning results (LR) proposed in the syllabus of the course Digital Design with Microcontrollers taught in the Electronic Engineering course of the Faculty of Engineering of the Universidad Distrital Francisco José de Caldas in Bogotá, Colombia. Students are provided with all the information related to the project, the design methodology, what is expected from the project, and how to evaluate the results of the work done. The proposed methodology shows the students that, from a practical project usually applied to the real environment, the theoretical information shown in the classroom is immediately applicable, increasing their motivation and willingness to work. In addition, another skill, teamwork, is reinforced by applying this type of teaching, since each member of the working group (three students per group) has a role in the project’s development. The low-cost development kit CY8CKIT-059 for PSoC5LP, manufactured by Infineon Technologies AG, is used in the course to apply the proposal. As a case study to demonstrate the methodology, the design of a data logger that stores humidity and temperature from a digital sensor, developed as one of several projects presented by students in recent semesters, is presented. When comparing the quantitative results obtained from the course in previous semesters with those obtained after applying the project-based learning methodology, a significant improvement can be seen: the percentage of students passing is significantly higher.

Published: August 2023

Deep learning and its variant techniques have surpassed classical machine algorithms due to their high performance gaining remarkable results and are used in a broad range of applications. However, adopting deep learning models over the cloud introduces privacy and security issues for data owners and model owners, including computational inefficiency, expansion in ciphertext, error accumulation, security and usability trade-offs, and deep learning model attacks. With homomorphic encryption, computations on encrypted data can be performed without disclosing its content. This research examines the basic concepts of homomorphic encryption limitations, benefits, weaknesses, possible applications, and development tools concentrating on neural networks. Additionally, we looked at systems that integrate neural networks with homomorphic encryption in order to maintain privacy. Furthermore, we classify modifications made on neural network models and architectures that make them computable via homomorphic encryption and the effect of these changes on performance. This paper introduces a thorough review focusing on the privacy of homomorphic cryptosystems targeting neural network models and identifies existing solutions, analyzes potential weaknesses, and makes recommendations for further research.

Published: August 2023

The objective of this research is to describe the impact of gadget usage on the social and linguistic development of primary school students. The study used the mixed-methods sequential explanatory design. In determining the subject of the research—namely, 251 children consisting of second graders and fifth graders in Jakarta, Indonesia—we used purposive sampling. Purposive sampling was also used to determine the research location—namely, two public primary schools and two private primary schools in Central and South Jakarta. As for the data collection, questionnaires, interviews, and observations were employed, resulting in quantitative data presented statistically in tables and charts. The regression analysis performed to figure out the social development of the primary school students in Jakarta resulted in a score of 0.000, suggesting that the students possess social capabilities and skills displayed when they are among their peers—namely, understanding the emotional conditions of their friends, accepting themselves, and maintaining friendship. The students are also capable of comprehending the thought, feeling, and behavior of their friends, thus enabling them to develop well-being skills. A regression analysis score of 0.001 suggests that gadget usage at home and at school influence the linguistic development of the primary school students. Our qualitative analysis corroborates the regression score by suggesting that gadget usage improves the growth and development of the social and linguistic behavior of the primary school students. In light of the impacts of gadget usage on the social and linguistic development of the primary school students, it is highly recommended that both the school and the parents put in place a code of ethics and educational guidance regarding gadget usage to mitigate the negative impacts of gadgets on students.

Although artificial intelligence enables the detection of abnormalities in medical images and is widely used as a computer vision technology, many researchers have focused on the detection of only one disease related to diabetes, which is diabetic retinopathy. In fact, patients face a significant risk of two other illnesses: cataract and glaucoma. In this article, we examined the diagnosis of these three eye diseases caused by diabetes and compared four approaches to classify these conditions. The proposed approaches are based on the transfer learning technique. We started by filtering, preparing, and augmenting the dataset, then applied transfer learning for feature extraction using two different architectures: VGG16 and RESNET50. We also investigated the impact of using contrast limited adaptive histogram equalization on the accuracy and precision of the models. This filter was used in a pre-training step for diabetic retinopathy diagnosis and in this paper proved its efficiency for glaucoma and cataract too. The final layers were replaced by Random Forest for classification. Models performed acceptable accuracies of 89.17% and 85.64% without operating contrast-limited adaptive histogram equalization and achieved better results when applying contrast-limited adaptive histogram equalization, with an accuracy of 97.48% and 96.66% for VGG16 and RESNET 50, respectively.
