Photochlorination of Anthracene in Saline Ice under Simulated Solar Light
Authors: Li Yujie , Hu Xuefeng , Xie Hao , Cai Beichuan , Bai Yaxing
Published: April 2024

Polycyclic aromatic hydrocarbons (PAHs) can undergo photochemical reactions in chlorine-containing environments, generating chlorinated polycyclic aromatic hydrocarbons (ClPAHs). This phenomenon has been confirmed in aqueous and soil environments, while was previously overlooked in saline ice. Thus, this study aimed to investigate the photochemical chlorination behavior of anthracene (ANT) in saline ice. Under photoexcitation, the ground state ANT generates the singlet state ANT (1ANT*), which is transformed into the triplet state ANT (3ANT*) via intersystem crossing. Simultaneously, the oxygen receives electrons and further reacts to form the hydroxyl radical (·OH). The ·OH reacts with chloride ions (Cl−) to produce chlorine radicals (·Cl). The ·Cl then reacts with 3ANT* to form monochloroanthracene (9-ClANT, 2-ClANT). The resulting monochloroanthracene further reacts with ·Cl to form dichloroanthracene (9,10-Cl2ANT). Lower temperature, higher salinity, and dissolved organic matter are facilitated to generate ClPAHs, which may show negative impacts on the ecological environment.

Published: April 2024

The automobile industry is shifting from internal combustion engine vehicles (ICEVs) to hybrid electric vehicles (HEVs) or electric vehicles (EVs) extremely fast. Our calculation regarding the most popular private car brand in Bangladesh, Toyota, shows that the life cycle cost (LCC) of a Toyota BZ3 (EV), USD 43,409, is more expensive than a Toyota Aqua (HEV) and Toyota Prius (HEV), but cheaper than a Toyota Axio (ICEV) and Toyota Allion (ICEV). It has been found that about a 25% reduction in the acquisition cost of a Toyota BZ3 would lower its LCC to below others. EVs can be a good choice for those who travel a lot. Changes in electricity prices have little effect upon the LCC of EVs. With the expected decline in the annual price for batteries, which is between 6 and 9%, and the improvement of their capacities, EVs will be more competitive with other vehicles by 2030 or even earlier. EVs will dominate the market since demand for alternative fuel-powered vehicles is growing due to their environmental and economic advantages.
The topos of Hutsulshchyna in Yaroslav Barnych’s operetta “Hutsulka Ksenia”
Authors: Zhdanko Andrii , Oliinyk Svitlana
Published: April 2024

Yaroslav Barnych (1896–1967), whose name after need emigration was erased for a long time from the history of national music, is a bright figure in the Ukrainian musical culture of the middle of the 20th century, a talented composer who was called the “Ukrainian Lehár”, an excellent teacher, a gifted conductor and an active social activist-educator. Among the genre palette of the artist’s works, the operetta genre stands out. Despite the fact that the composer created only four examples of this genre, Ya. Barnych managed to implement revolutionary changes of it and gain the status of “creator of modern Ukrainian operetta”. The operetta “Hutsulka Ksenia”, which fully expresses the main features of the renewed genre, remains the most famous and brightest among his musical and stage compositions. Today, this operetta is performed with great success in many cities of Ukraine and beyond, and the musical and stage heritage of the composer is of great interest to modern musicologists-researchers. The purpose of the article is to identify the signs of the embodiment of traditional Hutsul musical culture in Barnych’s operetta “Hutsulka Ksenia”. The innovativeness of this study consists in involving into the field of domestic musicology of the work by Ya. Barnych thanks to a comprehensive analysis of this operetta carried out for the first time. The means of modernization of this genre in Ukrainian music on its example were traced; the socio-cultural and autobiographical markers were determined, and the specifics of the use of elements of the Hutsul folklore musical tradition in the work was identified. It is concluded that Barnych’s “Hutsulka Ksenia” presents the genre of modern Ukrainian operetta (which is essentially similar to Neo-Viennese operetta), contains certain autobiographical and socio-cultural markers (which allow us to understand the idea of the work), demonstrates the connection of the musical material with the traditions of Hutsul musical culture.

Published: April 2024

Key Points

This study reviews the willingness to use kidneys from donors who have experienced AKI during transplantation and provides a thorough analysis of the existing literature.

While delayed graft function is more common, primary nonfunction and acute rejection rates appear comparable, as do allograft function and graft survival compared with non-AKI donor kidneys.

Considering the shortage of available organs and the high mortality rate of patients on dialysis, the use of donors with AKI as a source for kidney transplantation is a viable alternative.

Background

AKI is a common complication in hospitalized patients and may occur in potential kidney donors. Observational studies have suggested that kidney transplantation in patients with AKI is feasible and safe, but no systematic evaluation has been performed.

Methods

We performed a systematic review and meta-analysis to evaluate the outcomes of kidney transplantation in patients with AKI. We searched MEDLINE, Embase, Cochrane, Google Scholar, and other databases for studies reporting outcomes of donor kidneys with AKI. We included single-center, multicenter, and registry-based studies and analyzed them according to the definition and severity of AKI. End points were primary and delayed graft function (DGF), primary nonfunction (PNF), length of hospital stay, rejection, graft function, and patient and graft survival at 1, 3, 5, and 8–10 years after transplantation. This study was registered in PROSPERO, number CRD42021260088.

Results

We identified 33 single-center, four multicenter, and seven registry studies with more than 100,000 patients published between 2005 and 2022. Recipients from donors with AKI had a higher risk of DGF (relative risk, 1.51; 95% confidence interval [CI], 1.35 to 1.68). Graft function at discharge was worse in the AKI group (MDCrea [95% CI]: 0.96 mg/dl [0.36 to 1.56, I2=96%], MDGFR [95% CI]: −8.88 ml/min per 1.73 m2 [−15.32 to −2.44, I2=93%]), but improved thereafter and was similar in both groups at 3 months after transplantation (MDCrea [95% CI]: −0.05 mg/dl [−0.18 to 0.07, I2=0%], MDGFR [95% CI]: −1.83 ml/min per 1.73 m2 [−5.29 to 1.63, I2=91%]). Primary nonfunction and patient and graft survival were similar at 1, 3, 5, and 8–10 years after transplantation. There were no differences in rejections regardless of AKI definition and severity.

Conclusions

Transplantation of kidneys with AKI is associated with satisfactory short-term and long-term outcomes and should be pursued to increase the donor pool.

Published: April 2024

The article is devoted to the study of the problem of utilisation of the Buzky estuary sludge contaminated with chemical and radionuclide pollutants due to a significantan thropogenic load on its hydro ecosystem: use in transport logistics and through sewage discharges. Since these sludges can be a valuable fertiliser for solving many environmental problems that require the provision/introduction of organic matter/fertilisers, the article investigates the possibility of using dredged contaminated estuarine sludges for remediation of the surface of sludge pits at Mykolaiv Alumina Plant LLC. A method of simultaneously solving two separate environmental problems of Mykolaiv (disposal of contaminated sludge from the Buzky estuary and deflation of toxicants from the surface of red sludge pits) is proposed.
INDUSTRIAL CYCLONE-ROTORY DUST COLLECTOR
Authors: Kuznietsov S. , Wenher O. , Bezpalchenko V. , Semenchenko O.
Published: April 2024

Cyclone equipment is easy to manufacture and operate, versatile and economical, but its main drawback is the inability to capture finely dispersed dust. The article discusses the most important characteristics of the highly efficient industrial cyclonic rotary dust collector developed by us. The apparatus implements the principle of two-stage separation of heterogeneous dust-gas systems in a centrifugal field. In the first stage, working on the principle of a cyclone, and in the second - working on the principle of a rotary dust collector. During operation of the apparatus, a higher pressure on the periphery of the rotating part returns a concentrated dusty flow with a low gas flow to the cyclone part. Formed by a gap, between the cyclone body and the dividing cone, a closed circuit connects the output and input of the cyclone-rotational dust collector to each other. There is a negative feedback - an effective control mechanism for such complex probabilistic systems as gas heterogeneous curvilinear flows. Negative feedback stabilizes the processes occurring in such flows. The energy of the electric motor is used in the cyclone-rotational dust collector  for the movement of dusty gas, concentration, coagulation of fine dust, its return from the rotary to the cyclone zone, dispersion and capture, with the aim of saving energy and material resources.
The main task of the theory of centrifugal separation of dusty flows is to find the minimum diameter of a particle that has a practically perceptible relative radial velocity. Known deterministic models of centrifugal separation are either too simple and ignore many factors that determine the process, or in attempts to account for them are too cumbersome and difficult to solve, although they are also not free from various assumptions and limitations. The stochastic model takes into account the integral set of various influences on the radial drift of the Stokes particle from the center to the periphery of the swirling flow. The paper presents the results of the study of the structure of the three-dimensional two-phase gas flow with highly dispersed inclusions in cyclonic-rotary dust collectors using 3D geometric models with the aim of visualizing these flows using computer graphics methods. Numerical studies were carried out using the k-e model of turbulence with scaled wall functions.
METHOD OF CHOOSING A TECHNOLOGICAL MEASURE OF ENVIRONMENTALLY SAFE DRAINAGE IN THE SETTLEMENTS OF UKRAINE LOCATED ON EUTROPHED WATER
Authors: Teliura N. , Ivashchenko Y.
Published: April 2024

In the settlements of Ukraine, four types of wastewater drainage systems are used. For all these systems, despite their distinctive differences, the main features that cause technical and ecological problems are identified. It is shown that the gradual reorganization of existing drainage systems of settlements are located at eutrophic water bodies are especially relevant. Due to the unsatisfactory state of wastewater systems, in emergency situations on sewer networks and with insufficiently cleaned surface and drainage wastewater, a significant amount of organic and biogenic substances, pathogenic microflora get into water bodies. This leads to an increase in the ecological unsafety of water bodies. Based on the analysis of literature data, the tasks are identified that need to be solved to achieve the goal.
LEVELING UP KNOWLEDGE MANAGEMENT: HARNESSING GAMIFICATION FOR EFFECTIVE KNOWLEDGE ACQUISITION, DISTRIBUTION, DISSEMINATION, AND SHARING
Authors: Aleksandra Witoszek-Kubicka
Published: April 2024

The paper addresses the issue of motivating employees to engage in behaviors related to knowledge transfer. This challenge is prevalent in numerous contemporary organizations that seek methods and tools to enhance the effectiveness of acquiring, distributing, disseminating, and sharing knowledge. Within the scope of the article, preliminary research was conducted, including a systematic literature review and a case study based on in-depth interviews and documentation analysis. The aim was to address the following questions: P1: What is the impact of a gamification project on knowledge transfer? P2: Does any objective of internal gamification also aim to support knowledge transfer? The results indicate that knowledge transfer is a pivotal element across all objectives of internal gamification, and the gamification elements positively influence the shaping of desired behaviors within its sub-processes. While these findings stem from preliminary research, they unequivocally underscore the significance of the issue and the necessity for further investigations into the implementation of gamification within organizations, particularly in the context of knowledge transfer.

Authors: Katar Oğuzhan , Yıldırım Özal
Published: April 2024

Malware detection and classification have become critical tasks in ensuring the security and integrity of computer systems and networks. Traditional methods of malware analysis often rely on signature-based approaches, which struggle to cope with the ever-evolving landscape of malware variants. In recent years, deep learning techniques have shown promising results in automating the process of malware classification. This paper presents a novel approach to malware image classification using the Vision Transformer (ViT) architecture. In this work, we adapt the ViT model to the domain of malware analysis by representing malware images as input tokens to the ViT architecture. To evaluate the effectiveness of the proposed approach, we used a comprehensive dataset comprising 14,226 malware samples across 26 families. We compare the performance of our ViT-based classifier with traditional machine learning methods and other deep learning architectures. Our experimental results showcase the potential of the ViT in handling malware images, achieving a classification accuracy of 98.80%. The presented approach establishes a strong foundation for further research in utilizing state-of-the-art deep learning architectures for enhanced malware analysis and detection techniques.

Published: April 2024

Call centers play a key role in the management of customer relationships in the modern business world. However, the growing demand for their services presents significant challenges, particularly in terms of staffing and handling increasing call volumes. This paper addresses these issues by presenting an AI-driven text classification framework tailored for the Republic of Turkiye Ministry of Trade Call Centre (MTCC), with the aim of automatically routing calls to relevant departments. Using a specific dataset of 20,000 phone call texts collected from the MTCC, the study employs TF-IDF, Word2Vec, and GloVe text vectorization techniques and applies various machine learning algorithms such as K-Nearest Neighbours, Naive Bayes, Support Vector Machines, Adaptive Boosting, Decision Tree and Random Forest for text classification. Through a comprehensive analysis, the study answers key research questions regarding optimal classifiers and vectorization methods. The proposed solution not only improves the efficiency of MTCC's call routing but also provides researchers with practical insights regarding Turkish text classification. The results indicate that a combination of the Random Forest classifier and Word2Vec text vectorization method is the optimal model that can manage to route calls in real-time.

1946: Um curso de desenho de propaganda e artes gráficas e o cenário de configuração do desenho projetual brasileiro
Authors: Perrotta Isabella
Published: April 2024

A partir do Curso de Desenho de Propaganda e de Artes Gráficas, coordenado pelo artista Tomás Santa Rosa, em 1946, na Fundação Getulio Vargas no Rio de Janeiro, este artigo visita o cenário em que os campos do design gráfico e da publicidade começavam a se configurar no Brasil, suas heranças vindas das artes plásticas, a incipiente valorização da formação técnica, e suas relações com o desenvolvimento do país. Trata-se de uma pesquisa exploratória, de cunho histórico, baseada em dados documentais e bibliográficos. Os documentos consultados, nos acervos da Fundação, evidenciaram diversas outras iniciativas de formação técnica em desenho, a partir de 1948. Vislumbrou-se, então, uma demanda por novos profissionais a partir da industrialização e da modernização do país que, indiretamente, repercutiu na institucionalização de cursos de design.
Las toxicomanías: su importancia social y el concepto moderno de su tratamiento
Authors:   , Itzigsohn José Alberto
Published: April 2024

Cuando un médico trata a un toxicómano, no tiene ante sí sólo a un enfermo, sino también a un ser influenciado por organizaciones delictuosas que lo explotan y tratan de hacerlo persistir en su enfermedad. Las armas terapéuticas del médico son débiles, si no se ven acompañadas de una acción orgánica de orden nacional e internacional, son a su vez indispensables. La lucha contra las toxicomanías implica pues, una faz médica y otra de carácter público y social. Para exponer el alcance de la faz médica, se puede tomar el ejemplo de la lucha contra el alcoholismo, que tiene en su haber logros de importancia.
Tratamiento de las hemorragias masivas por úlcera gástrica y duodenal
Authors:   , Baamonde José Francisco
Published: April 2024

Esta gravísima complicación de la úlcera gastroduodenal, ha sido desde siempre un problema sombrío para los clínicos y cirujanos que mancomunados en lograr una solución satisfactoria no han escatimado esfuerzos; abundando la bibliografía en innumerables tratamientos que nos hablan de por sí, de la inquietud que la misma ha suscitado y de la inseguridad y desconfianza conque el médico ha tenido que obrar en estos casos, colocado frente a las divergencias y controversias que los distintos autores señalan como camino a seguir. Lo cierto es que si bien esta complicación no debiera existir en la época actual, pues la úlcera gastroduodenal es una enfermedad que muy pocos secretos guarda, ella existe; y debemos decir que casi el 70 % de las hemorragias masivas originadas en el tracto digestivo corresponde según Bockus H. a la úlcera gastroduodenal y el otro 30 % restante los refiere a procesos gástricos, duodenales, esofágicos .etc. Colocado frente a una hemorragia de considerable magnitud nos debe inducir a pensar en la profunda alteración que en el estado general del enfermo se está realizando, comprometiendo en sumo grado su vida, adquiriendo el cuadro todas las características de una situación clínica verdaderamente de urgencia tanto o más que la otra gran complicación de la úlcera, me refiero a la perforación y que de no mediar una terapéutica inmediata y eficaz, el desenlace será fatal.

Utilización de algunas materias primas nacionales en la obtención de resinas sintéticas del tipo fenol-formol
Authors:   , Daniel Alfredo
Published: April 2024

Nuestro país carece hasta el presente de derivados del alquitrán de hulla, debido a que dicha industria no ha alcanzado pleno desarrollo por carecer de la materia prima básica: la hulla ó carbón fósil. Hasta 1945 los yacimientos de hulla en nuestro país eran de pequeña producción, siendo así explicable el poco auge de dicha industria. Hasta el presente, la superusina "Eva Perón" de la Capital federal ha destilado en retortas una mezcla constituida por cantidades variables de carbón de hulla de procedencia inglesa, coke de petróleo y asfaltita. Con el descubrimiento del gran yacimiento carbonífero de Río Turbio y zonas adyacentes cuyo contenido en carbón fósil ha sido estimado en más de 300 millones de toneladas, se superará la etapa de escasez de hidrocarburos aromáticos, fenoles, naftaleno y otros derivados del alquitrán, que han dificultado el desarrollo de la industria química argentina de carácter orgánico, vinculada a plásticos, resinas sintéticas, colorantes, etc. Hasta tanto este carbón no se traslade en grandes cantidades a la Capital Federal, ó se procese en la mina, las dificultades para la importación de fenoles, cresoles, etc., impedirán el desarrollo normal de las industrias, que dependen de estas materias primas, aunque la Fábrica Militar de Campana podría suministrar ciertos tipos de hidrocarburos aromáticos, como benceno, etc., que podrían ser materias primas para la obtención del fenol. Por las razones expuestas se ha decidido estudiar las sustancias de tipo fenólico disponibles en el país obtenidas a partir de materias primas nacionales, que en nuestro caso fueron: 1) Productos derivados de la destilación de la superusina "Eva Perón" en la Capital Federal (alquitrán de hulla). 2) Productos derivados de la destilación destructiva de la madera (alquitrán de madera).

This study aims to improve the accuracy of the intrusion detection system model. It focused on LSTM and GRU methods proposed by several previous studies. The bidirectional layer was also tested to see if it improves model performance. Dataset used in the study was CIC IDS 2017. The dataset was divided into 3 parts, for training, validation, and testing purposes. Validation data was used to evaluate model performance in every training iteration. It helped to make the model would not overfit the training data. Furthermore, Dropout layer and L2 regularization were also added to the model architecture. The training model was done in a binary classification approach with a learning rate of 0.0001. We found that the stacked method reached accuracy 98.1087% in 100 iteration training. This result is slightly higher than LSTM, GRU, Bidirectional LSTM, and Bidirectional GRU. The method which contains LSTM layer performed its best accuracy using Tanh activation. Differently, GRU and Bidirectional GRU performed the best performance with Lrelu and Prelu activation function, respectively. All models could reach the plateau in the first 20 iterations, while in the next 80 iterations the model performance still could be fluctuately improved. Even though the model already reached the plateau in 20 iteration training, it is still possible for the model to slowly improve by using a small learning rate and by implementing Dropout layer and L2 regularization. Fluctuation of model performance implies that the highest model performance was not always reached in the last training iteration. ModelCheckPoint could help to overcome the issue. In addition, the Bidirectional layer increased the complexity of the model which certainly increased training duration. The bidirectional layer improved the performance of the GRU method, but it did not improve the performance LSTM method.

Lung cancer is one of the deadliest types of cancer characterized by the uncontrolled growth of cancer cells in the lung tissue due to the accumulation of carcinogens. Lung cancer ranks second in the most cases with 2.206 million new cases and ranks first in deaths. This lung cancer often does not cause symptoms in the early stages, because it only appears after the tumor is large enough or the cancer has spread to surrounding tissues or organs, so it is necessary to have early detests to prevent severity and determine follow-up treatment. This study aims to classify lung cancers using digital pathology images with data of 15000 images obtained from the LC25000 dataset containing 5,000 images for each class. The method used in this classification process uses convolutional neural networks (CNN) which is one of the implementations of Deep Learning used for digital image processing. Using this method, the doctor can diagnose and find out the type of lung cancer quickly without spending much time. Thus, the faster the prediction results received by the doctor / health expert, the faster the next action or handler will be, this study produces a fairly accurate accuracy value even though it uses a shallow CNN architecture because it only consists of 5 layers with 3 convolution layers and 2 fully connected layers, with the resulting accuracy value of 98.53%.
