Improving the heat transfer characteristics of miniature two-phase thermosyphons with nanofluids based on Ukrainian natural alumosilicates
Authors: Kravets Vlаdіmіr , Hurov Dmytro , Moraru Vasily
Published: September 2023

In order to improve the heat transfer characteristics of miniature thermosyphons, a study of the processes of heat transfer by them using water and nanofluids as heat carriers was carried out. A water mixture based on nanoparticles of Ukrainian natural aluminosilicate - attapulgite with the addition of 0.1 % carbon nanotubes was used as nanofluids. The data of the study of the maximum heat flow and the minimum thermal resistance of copper thermosyphons with an internal diameter of 5 mm and a length of 700 mm are presented. Orientation of thermosyphons in space: vertical. The length of the heating zone varied from 50 mm to 200 mm, with the same amount of heat-carrier. The fill factor varied from 0.44 to 1.93.
A comparison was performed of the heat transfer capabilities of thermosyphons with water and with a nanofluid with a mass concentration of 0.5 %. It has been shown that nanofluid thermosyphons transmit 53 % more heat flow compared to water, and thermal resistances are reduced by 25 %.
The influence of the concentration of nanoparticles on the heat transfer characteristics of thermosyphons is shown. Nanofluids with concentrations (0.1 %, 0.5 %, 0.7 %) showed the same level of thermal resistances, with an increase in maximum heat flows compared to distilled water. Thus, when compared with the lowest concentration (0.1 %), the use of 0.5 % nanofluid gives an advantage of up to 40 %, and 0.7 % – an advantage of up to 51 %. This is explained by the appearance of a specific porous structure of anisometric nanoparticles on the heating surface, which contributes to the appearance of additional centers of vaporization during boiling and improves the heat transfer characteristics of thermosyphons.
Thus, the use of such thermosyphons with nanofluids when cooling elements of electronic equipment could improve their functional characteristics

The aim. The objective of the research was to study the pharmacological activity of dry extract of Sakhalin willow shoots – DEWS against the background of experimental thrombophlebitis.
Materials and methods. Dry extract of Sakhalin willow shoots (DEWS) was the object matter of the present research and served as a therapeutic and prophylactic agent. In the experiment conducted, rabbits weighing 2.0 – 2.5 kg were used. The animals were divided into three groups. Group 1 was a control group; group 2 were animals that had been intragastrically injected with DEWS at a dose of 30 mg/kg prior to modelling thrombophlebitis; group 3 similarly received Eskuvit 20 mg/kg as a reference drug – pills (JSC Halychpharm, Ukraine). The dose for animals was recalculated, taking into account body weight according to the Rybolovlev method.
Experimental thrombophlebitis was caused by injecting an intravenous solution of 2 % lugol at a dose of 0.1 ml into the marginal vein of the ear. Statistical data processing was carried out using the Statistica for Windows 11.0 program based on variance analysis for repeated measurement data using the Mann-Whitney criteria at a probability level of p<0.05.
Results. Against the background of the development of experimental thrombophlebitis in rabbits, the development of thrombosis of the ear vein and the inflammatory process of adjacent tissues were observed. The inflammatory process was accompanied by pronounced hyperemia and oedema. Prophylactic administration of DEWS for 6 days contributed to a decrease in the inflammatory process already on the 5th day of observation. The area of the injured area was 20 % smaller than in the control pathology group. The therapeutic and prophylactic effect of herbal medicine can be explained by the content of flavonoids and salicylates in its composition. Eskuvit showed a less pronounced thrombolytic effect in terms of its influence on thrombosis and thrombolysis.
Conclusions. The administration of DEWS in the therapeutic and prophylactic regimen at a dose of 30 mg/kg has a pronounced anti-inflammatory, thrombolytic and venoprotective effect in experimental peripheral venous thrombophlebitis in rabbits. The results of the studies obtained allow us to recommend DEWS as a promising venoprotective agent with thrombolytic activity

Published: September 2023

ABSTRACT Objectives: Analyze wrist wrap influence on the values of maximum handgrip strength and dynamic resistance. Methods: A controlled randomized cross-over trial including 54 Crossfit participants randomly assigned to two groups. Group 1 began the series of tests with control wrapping, and Group 2 started with functional wrapping. Alternate series of four dynamic grip strength resistance tests were performed, and the resistance and fatigue values were calculated. Results: The values obtained from the grip tests did not indicate any effect from the wrist wrap for an increase in maximum grip strength (35.7 vs. 35.6 kg; p=0.737) or greater endurance (78.2 vs. 77.8%; p=0.549). Fatigue was also equal in both groups (mean differences between the groups: 0.1 kg, CI= -0.7–0.8; p=0.779). Conclusion: The hypothesis that using a wrist wrap increases maximum strength and dynamic handgrip endurance was rejected in this study. Evidence Level I; Randomized control trial .

Published: September 2023

Resumo O estudo teve como objetivo analisar a assistência às pessoas com transtornos mentais em conflito com a lei na perspectiva de gestores e profissionais de saúde. Trata-se de um estudo de caso, de abordagem qualitativa, realizado em janeiro de 2020, com 10 profissionais que atuavam no Hospital de Custódia e Tratamento Psiquiátrico do Estado do Rio Grande do Norte. Para coleta de dados, utilizou-se um questionário sociodemográfico e entrevista semiestruturada. O conteúdo textual decorrente das entrevistas foi submetido à análise textual lexicográfica, com auxílio do software IRAMUTEQ, e a análise dos dados foi realizada a partir de literatura pertinente. Emergiram três categorias: As mudanças nas relações de trabalho e o impacto na assistência; A organização da Rede de Cuidado; e A assistência intramuros e os entraves para desinstitucionalização. Conclui-se que a assistência às pessoas com transtornos mentais em conflito com a lei é influenciada pelas relações de trabalho; tem dificuldades relacionadas à estrutura física e à dinâmica das instituições; enfrenta entraves para garantir a desinstitucionalização, ao passo que fragmenta os vínculos e não implementa o Projeto Terapêutico Singular. Todavia, esforços têm sido empreendidos para articular a rede de cuidado de base territorial.

Resumo Buscou-se conhecer a compreensão de profissionais dos Núcleos Ampliados de Saúde da Família e Atenção Básica (Nasf-AB) sobre a utilização das Práticas Integrativas e Complementares em Saúde (PICS) na sua atuação no município de Jaboatão dos Guararapes-PE, entre julho e agosto de 2020. Trata-se de um estudo de abordagem qualitativa, de caráter exploratório, utilizando-se da análise de conteúdo de Bardin para tratamento dos dados. Foram entrevistados 12 profissionais, dos quais dez utilizavam PICS, sendo a maioria do sexo feminino, parda, com formação em terapia ocupacional, de 30 a 39 anos. A auriculoterapia foi a prática predominante, sendo utilizada na população e nas equipes apoiadas, de forma individual e coletiva, principalmente nos problemas de saúde mental e dores crônicas. Os resultados ainda evidenciaram benefícios, formas de uso, fragilidades e potencialidades das PICS. A falta de financiamento federal das PICS, a aprovação da Emenda Constitucional (EC) 95/2017 e o atual Programa “Previne Brasil”, são vistos pelos autores como grandes desafios ao fortalecimento do Nasf-AB e à institucionalização das PICS na APS.

Published: September 2023

Resumo Gestores e profissionais de saúde são os agentes responsáveis pela implementação das políticas públicas nos serviços de saúde, sendo de fundamental importância compreender as formas como agem no cotidiano. O objetivo desta pesquisa é analisar as condutas estratégicas de gestores e profissionais que intervêm na prevenção e no controle do câncer bucal. Trata-se de pesquisa qualitativa, realizada por meio de 23 entrevistas com gestores e profissionais de cinco municípios da região de saúde Metropolitana I do Rio de Janeiro e três entrevistas com o corpo técnico estadual. Realizou-se a análise da conduta estratégica prevista na Teoria da Estruturação de Giddens. Verificou-se que esses agentes, sensibilizados pelas representações do câncer na sociedade, se mobilizam como potenciais agentes facilitadores do acesso e criam alternativas informais aos protocolos mais restritores. No entanto, essa mobilização não costuma ocorrer no período anterior à suspeita do câncer, constituindo uma contradição importante. Destacou-se a importância da ampliação da atenção primária e do aperfeiçoamento das ações de promoção da saúde, prevenção do câncer e educação permanente para garantia do direito ao acesso ao diagnóstico e tratamento precoce do câncer bucal.

Published: September 2023

Resumo A avaliação de perguntas de questionário de inquérito de saúde no Brasil limita-se, na maioria das vezes, aos testes-piloto e debriefing das entrevistas. O objetivo do presente artigo é contribuir para preencher essa lacuna ao apresentar uma metodologia de avaliação cognitiva para identificação de perguntas potencialmente “problemáticas” quanto à sua formulação e o que ocorre, na interação entrevistador-entrevistado, ao aplicá-las em entrevistas com o uso de questionário padronizado em um inquérito regional de saúde. O estudo utilizou dois roteiros padronizados para identificação de dificuldades de redação e/ou compreensão e avaliação da interação entrevistador-entrevistado. Dentre as 513 perguntas do questionário individual de pesquisa, 68 questões foram indicadas como sendo potencialmente problemáticas à compreensão e comunicação pelos entrevistados. As perguntas que apresentaram problemas na sua formulação, com maior pontuação (>40), foram aquelas relacionadas à quantificação de tempo; ao grau de dificuldade para o autocuidado; à situação no trabalho e à estimação do rendimento. Dentre as perguntas apontadas como problemáticas na avaliação pelo Sistema de Apreciação de Perguntas (SAP), o autocuidado e horas trabalhadas estão entre aquelas que também tiveram pontuação alta na avaliação da interação.
GRAPE LEAF DISEASE RECOGNITION BASED ON A MULTISCALE MIXED ATTENTION RESIDUAL NETWORK
Authors: Gong Qi , Yu Xiao , Chen Cong , Li Wen , Lu Lina
Published: September 2023

A multiscale efficient channel attention spatial-residual network (MECAS-ResNet) is proposed in this paper. On the basis of ResNet50, the training speed and model volume are reduced by group convolution. Through multiscale convolution, the spatial attention and effective channel attention are fused into the model to improve the network's attention toward various regions of lesions. A Wasserstein generative adversarial network is used for data enrichment, and the resulting images are diverse and variable. The enriched dataset is fed into the MECAS-ResNet model for identification and comparison to other models. After the improvement, the optimal recognition accuracy reached 95.31%, which is 10.02% higher than that on the original dataset; the model size is only 30.88 MB; and the average F1-score reached 95.30%. The improved model has higher recognition performance for similar diseases in different degrees, which is better than other models. The data generated by the experiment can be used for grape disease recognition, which greatly reduces the cost of data collection and provides technical support for grape disease recognition and precise drug treatment.
THE NECESSITY OF TEAMWORK APPROACH IN ARCHITECTURAL DESIGN EDUCATION: AN ANALYTICAL STUDY
Authors: KHALEGHIMOGHADDAM Navid
Published: September 2023

Aim: This study intends to identify the processes of group design with students, the weak and strong areas of their activity in different phases, and to assess the implications of education in executing this activity by focusing on the principles of group design thinking in architecture. Method: A test was conducted among students from Tehran and Konya Technical Universities to investigate the influence of education on improving group design quality. This experiment was conducted by having three-hour drawing sessions and dividing the students into 8 groups. The single-variable test method was utilized because of the independence of the groups and the equality of their variances. Two preliminary exams were used to measure students’ lack of understanding and familiarity with group work, followed by an extra examination for the students involved in the issue. Results: The findings revealed that in group architectural design, group members focus largely on the design’s content, with team communication centred on two essential aspects: content analysis and process review. Conclusion: Teamwork in designing can be superior to solo effort, and proper training can increase this. It is felt that paying attention to the concept of group design and teaching it in architecture schools is useful.
Covert Hegemonic Masculinities and other Androcracies
Authors: Márquez Roa Ubaldo , Tovar Cabañas Rodrigo , Herrera Meza Grecia
Published: September 2023

The objective of this essay is to document how hegemonic masculinity is socially reproduced through almost imperceptible processes of androcracy, and concomitantly, to demonstrate how androcracy strategically influences the professional development of Mexico's social capital, since meritocracy from androcracy is a simulation game of female promotion. All these androcratic processes exclude men and women of the high academic profile from high and mid-high positions, thus originating alterations in daily politics. To document this androcratic process, the text is divided into three sections: the first part presents the state of the art of masculinity; in the next section, using qualitative techniques and participant observation methods, three examples of androcracy are described, in different geographical and socio-political scales: the international example analyzes the case of the NXIVM sect, the national example analyzes the case of the National System of Researchers of Mexico, and the local example analyzes the case of the Universidad Veracruzana. The most relevant results, which indicate that psychological control continues to be an androcratic mechanism used to try to manipulate women with a high academic profile.

Authors: Mardones Leiva Karen , Oyarzún-Farías María de los Angeles
Published: September 2023

El estudio tuvo por objetivo explorar las representaciones sobre Género, Masculinidad y Hombres entre estudiantes de pregrado de instituciones de educación superior de Valdivia, Chile. El diseño fue no experimental, transeccional y exploratorio, utilizando la técnica de recogida y análisis de datos denominada redes semánticas naturales. Participaron 137 estudiantes de diferentes carreras, identidades de género y orientaciones sexuales. Los resultados muestran que las representaciones sobre Género se han desplazado desde sexo y mujeres hacia Identidad; para Masculinidad la red se condensa en torno a Hombre; y para Hombres el núcleo es Género, siguiéndole de cerca Machismo, Persona y Sexo. Las asociaciones para cada palabra concepto estímulo son amplias, y se encuentran cambios respecto a la literatura. Se concluye que estudiantes de pregrado poseen mayor bagaje conceptual vinculado a los estudios de género, que podría entenderse por el abordaje cada vez mayor de sus temáticas vinculadas al interior de las universidades gracias a los movimientos feministas liderados por estudiantes universitarias.
Discurso Político y Representaciones Sociales de la Discapacidad en las Estrategias Institucionales de Cuidados Familiares
Authors: ORTÍZ-AMO ROCÍO , MARTÍNEZ-SALVADOR ISABEL MARÍA , MUYOR-RODRÍGUEZ JESÚS
Published: September 2023

El trabajo presentado hace un análisis crítico del discurso de la política social en Andalucía con relación a los cuidados familiares. Centrado particularmente en las representaciones sociales de la discapacidad que se desprenden del cuidado familiar. El objetivo fue contribuir a la reflexión sobre las formas de constituir el objeto público de atención y protección social de los cuidados a las personas con diversidad funcional dentro del entorno familiar. La metodología llevada a cabo ha sido cualitativa. Las principales técnicas de investigación son la revisión documental y el análisis crítico del discurso de la normativa andaluza que regula la protección social. Desde una perspectiva hermenéutica examinamos prácticas concretas de intervención social, triangulando el análisis crítico del discurso con el conocimiento multisituado y la observación participante. Las políticas públicas de cuidados en Andalucía representan a las personas con diversidad funcional como dependientes. Las personas con diversidad funcional no son consideradas autosuficientes para cuidar de sí mismas, quedando atrapadas bajo nociones de fragilidad, indefensión, vulnerabilidad, protección y tutela. Se justifica un discurso centrado en el cuidado del/a cuidador/a familiar y los cuidados más básicos de las personas con diversidad funcional. En cambio, se desatienden responsabilidades públicas encaminadas a la participación social de las personas con discapacidad.
Impact assessment of uterine artery embolization on reproductive
Authors: Kalinina N. A. , Sulima A. N. , Rumyantseva Z. S. , Baskakov P. N. , Kalinin V. D.
Published: September 2023

Introduction. Uterine artery embolization (UAE) is an effective minimally invasive manipulation that has been widely applied in obstetric and gynecological practice. The expediency of using this method of surgical treatment in patients with reproductive plans is still controversial. The main clinicians' concerns are the risk of developing local endometrial ischemia able to lead to habitual miscarriage, premature birth and pathological placentation as well as decreased ovarian reserve due to impaired adequate ovarian blood supply.

Aim: to analyze the literature data regarding UAE effect on reproductive function.

Materials and Methods. The search for literature was carried out in databases Web of Science, eLibrary, Scopus, PubMed/MEDLINE. We selected articles for the years 1995–2023 devoted to assessing UAE influence on reproductive function. The articles were searched by the keywords "embolization", "uterine arteries", "reproductive function", "prognosis", "assessment". No methodological filter was used to exclude the omission of suitable articles. The study included full-text sources and literary reviews on the subject under study. Articles that are not directly related to the subject UAE were excluded from the review. In order to avoid the inclusion of duplicate publications if two same author studies were found, the study period of each author was assessed, and if publication dates coincided, the most recent publication was selected.

Results. Based on the review of domestic and foreign literature sources over recent years, it can be concluded that there are restrictions on the frequency and outcomes of pregnancy in such cohort of patients who underwent UAE. Many patients included in existing studies and case reports have variable factors complicating direct analysis or comparison such as age of patients, previous spontaneous abortions, previous uterine surgery, different techniques and professional training of X-ray endovascular surgeons, uncertainty of a woman regarding further reproductive plans and other forms of infertility, which can also distort research results. In addition, the most well-controlled studies often have small patients sample sizes not allowing to obtain meaningful clinical information from thereof.

Conclusion. Pregnancy is possible in women after UAE, and many of these pregnancies proceed without complications and lead to successful childbirth. The actual fertility rate after UAE remains uncertain, but is approaching 38.3 % based on the available published results.

Published: September 2023

Kiriş ve sac plaka yapılar otomotiv, havacılık, inşaat ve mimarlık gibi birçok alanda çeşitli amaçlarla kullanılırlar. Yük taşıyan kirişte eğilme ile deformasyon meydana gelir. Kirişlere benzer şekilde sac veya levha şeklindeki yapılarda kendi ağırlıkları ile veya yüzeylerine dik yönde kuvvet taşırken deforme olurlar. Bu tür yapılarda yükün emniyetle taşınmasının yanında, en az deformasyonun oluşması istenir. Bu çalışmada, kiriş ve sac parçaların kesiti, uzunluğu ve yükleme durumu sabit alınarak minimum deformasyonun elde edilmesi için mesnet noktalarının optimizasyonu gerçekleştirilmiştir. Mesnet konumları parametre olarak alınmış ve geliştirilen yazılım ile mesnet noktalarının konum optimizasyonları gerçekleştirilmiştir. Parametrik sonlu elemanlar modelinden farklı mesnet konumlarına karşılık gelen deformasyon değerleri elde edilmiştir. Python kodu ile yapay sinir ağı ve optimizasyon kodu geliştirilmiş ve deformasyon değerleri verilen mesnet konumlarına göre hesaplanmıştır. Geliştirilen yöntem iki ve üç mesnetli kirişler ile sac levha ve kaynakla birleştirilecek iki sac levha örnekleri üzerinde denenerek optimizasyon sonuçları elde edilmiştir. Her bir kiriş ve sac levha probleminde yayılı yük altında minimum deformasyon için mesnetlerin birbirlerine simetrik konumlandırılmaları gerektiği bulunmuştur. Optimum mesnet noktaları; iki mesnetli kirişte kenarlardan %21.89, üç mesnetli kirişte %13.57, sac levhada %19.13, kaynakla birleştirilecek iki sac levhada ise %14.42 uzaklıkta hesaplanmıştır.

Gerek odun gerekse diğer lignoselülozik malzemeler açık havada kullanıldıklarında güneş ışınları başta olmak üzere birçok etkilere maruz kalırlar. Bu malzemelerin daha uzun süre kullanılabilmeleri için bu etkilerin sonuçlarının bilinmesi gerekir. Bu çalışmada, perlit katkılı çam kabuğu ve kozalaklarından yapılan kalıplanmış kompozit malzemelerin hızlı (UV ışın altında) ve doğal yaşlandırma sonucu renk, parlaklık, kütle kaybı ile bazı fiziksel ve mekanik özelliklerinin malzeme içeriğindeki hammaddelerin parçacık büyüklüğü ve perlit oranıyla değişimi araştırılmıştır. Sonuçlara göre, yaşlandırma testi sonrasında toplam renk farkı değerleri için farklı renk değişimi ve yüksek renk değişimi kriterlerine rastlanılmamış; fakat yapay yaşlandırmanın L*, a* ve b* parametrelerini değiştirici etkide bulunduğu tespit edilmiştir. UV yaşlandırma sonrası A grubu malzemeler hariç tüm malzemelerin basınç dayanımının ve yoğunluğunun azaldığı; toprak testi sonuçlarına göre UV öncesi kütle kayıplarının büyük farklılıklar gösterdiği ve en fazla kaybın kozalak içeren örneklerde olduğu ölçülmüştür. UV muamelesinin kütle kaybı açısından tüm örneklerde birbirine yakın etki ettiği belirlenmiştir.
The Inflection of Latin Feminine Proper Names in the Old English Martyrology
Authors: Ruiz Narbona Esaúl
Published: September 2023

This paper focuses on the inflections of Latin feminine names in Old English. Whereas most Latin loanwords are perfectly integrated and behave like Old English words as far as their morphology is concerned, like scientific loans, names can take inflectional endings from both Latin and Old English. Ruiz Narbona (2023) has shown that, in the case of masculine names, the distribution of both types of inflections followed certain clear patterns. Following the model of that study, the analysis of the 125 tokens from the Old English Martyrology shows that certain rules can also be established in the case of feminine names. In general terms, the inflections of these names are modelled after Old English weak n-stems, although nominative inflections are invariably Latin. The case with the more widespread variation is the genitive, where both Old English and Latin inflections are consistently used. The latter, however, are heavily restricted to introductory sections and function solely as post-modifiers.
The origins of the Soviet Culture. Proletcult
Authors: Loktionov Mikhail
Published: September 2023

The subject of the research is Proletkult, the history and place of this movement in the Soviet culture of the 20th century. The article considers the ideas of one of the founders of Proletkult, Alexander Bogdanov.
 The main provisions of the concept of proletarian culture put forward by Bogdanov are analyzed, its distinctive features are described. Particular attention is paid to the role of culture in social transformation and the formation of a new society. The article allows a deeper understanding of the historical context of the emergence of proletarian culture and its significance for the development of socialist and communist ideology. The article also attempts to understand the meaning of culture and the purpose of the creator in the cultural construction of the new world. The scientific novelty of the work lies in the study of the concept of Proletcult in a broad sense, that is, understanding it not only as a phenomenon in the context of contemporary art, but perceiving it as a component of human culture, including, among other things, the culture of production, the culture of thinking and even the culture of human relations. This is possible when studying the works of Bogdanov, devoted to the development of human relations in the transition from one social formation to another, a newer stage in the development of society. It is shown that the deepest understanding of the new culture (and not just art) is present in the works of Bogdanov, and not in the manifestos of the creators of contemporary art.

Influence of exhaust manifold modification on engine power
Authors: Bober Bartosz , Andrych-Zalewska Monika , Boguś Piotr
Published: September 2023

The article deals with the subject of the impact of an exhaust system on the power of the internal combustion engine. In particular the article shows the possibility of increasing a power of the gasoline drive unit, interfering only with an exhaust system. The purpose of the tests carried out is to compare the results of measurements from the chassis dynamometer before and after the modification, and additionally to perform simulations for the key parts of the system in terms of shaping the power and torque curves. The analysis includes a simulation model of the exhaust gas flow through the serial manifold and also the sport manifold, especially the pressure distribution and the course of the velocity vectors at the characteristic points of the element. Before obtaining the final results of power measurements on the sport units, the roughness of the steel from which the collectors were made was also measured. The final stage is the measurement of power on the new exhaust system. The obtained results of power measurements and simulations were presented in the form of a summary, which focused on the impact of individual fluid mechanics phenomena on the formation of power and torque curves and detailing the advantage of the new exhaust system in comparison with factory system in terms of increasing the performance of the tested vehicle.

The paper presents data on the carbon (δ13С) and oxygen (δ18О) isotopic composition of the carbonate rock constituent (CRC) and carbon (δ13C) of dispersed organic matter (SOM) of rocks of the Shumnaya, Inikan and Kuonamka Formations of the Lower-Middle Cambrian of the Siberian Platform. Dependence of the carbon and oxygen isotopic composition of CRC on the facies subtype of domanicoid deposits of the Cambrian was revealed. The interrelation of the carbon isotope composition of DOM with depositional conditions of sediments of the Lower and Middle Cambrian was considered. In the south-east of the Siberian Platform, Lower Cambrian carbonate deposits with carbon anomalous isotopic composition of CRC (δ13Сср = 6,6 ‰) and carbon of DOM (δ13С = –36,5 ‰) were found.
Successful nonoperative management of a simultaneous high-grade splenic injury and devascularized kidney in Australia: a case report
Authors: Nguyen Peter Thanh Tam , Hsu Jeremy M.
Published: September 2023

Severe blunt injuries to isolated solid abdominal viscera have been previously managed nonoperatively; however, management algorithms for simultaneous visceral injuries are less well defined. We report a polytrauma case of a 33-year-old man involved in a motorbike collision who presented with left-sided chest and abdominal pain. Initial imaging demonstrated multiple solid organ injuries with American Association for the Surgery of Trauma (AAST) grade V splenic injury and complete devascularization of the left kidney. The patient underwent urgent angioembolic coiling of the distal splenic artery with successful nonoperative management of simultaneous grade V solid organ injuries.
Release of microfibers from surgical face masks: an undesirable contributor to aquatic pollution
Authors: Hasan Jabed , Shahriar Sheik Istiak Md , Shahjahan Md
Published: September 2023

The worldwide usage of surgical face masks (SFM) has increased rapidly during the COVID-19 pandemic. Its degradation possibly produces billions of microplastics (MPs) in the environment. To quantify the release of microfibers (MFs), unused SFM were treated with eight different aqueous solutions, each with five replications in two categories, i.e., freshwater (FW) treatments [800 mL FW, 40 mL of 95% alcohol + 800 mL FW, 40 mL of 30% H2O2 + 800 mL FW, and 4 g sodium dodecyl sulfate (SDS) + 800 mL FW], and saltwater (SW) treatments (800 mL SW, 40 mL of 95% alcohol + 800 mL SW, 40 mL of 30% H2O2 + 800 mL SW, and 4 g SDS + 800 mL SW) at 25 °C for 60 days. The predominant MFs disposed from SFM were transparent and sized between 1.0 to < 0.5 mm. The mean highest amount of MFs observed was 4,911.3 (1-day) and 6,180.24 (30-day) in sodium dodecyl sulfate (SDS) mixed with SW, and 7,269.7 (60-day) in SDS with FW. The greatest number of MFs released per day was 275 (SDS in SW), followed by 193 (SDS in FW). The results indicated that if different kinds of water are mixed with detergent (SDS), it could accelerate the disposal of MP, whereas SW has considerably higher ability to release more MFs in a shorter time period compared to FW. Furthermore, this study implied that the inappropriate dumping of SFM could unfortunately escalate the preexisting MP pollution in the aquatic environment, which could negatively affect the aquatic living beings.

The handling of slum areas in Banjarmasin City uses more restoration patterns than renewal and resettlement patterns, and is carried out on land locations only, while riverbank slums are more directed towards rejuvenation and relocation patterns. Evaluation of riverbank space after the arrangement of slum areas in Banjarmasin City, South Kalimantan Province needs to be done in order to analyze the planning principles of handling riverbank slum areas after the implementation/arrangement process and see what factors can determine the success of the handling. Data collection techniques were carried out by literature review, field observations/observations, interviews/FGDs, and distributing questionnaires/digital questionnaires (google form). The sample selection technique used was purposive sampling. The data analysis method used is qualitative and quantitative, which combines descriptive research and percentage numbers. The findings were obtained in the form of analysis of planning principles in the form of slum handling indicators, the level of collaboration of basic elements of slum handling stakeholders and the extent of public/open space in the handling area. then this research also produces factors that determine the success of handling in the form of the level of community satisfaction by utilizing well-operational development infrastructure.

Companies or entrepreneurs must better understanding customers data in all aspects, including detecting similarities and differences among customers, predicting their behavior, and offering better options and opportunities to customers. Customer segmentation is carried out to obtain this information, which is part of CRM (Customer Relationship Management). One of the general models in the application of customer segmentation is the RFM (Recency, Frequency, and Monetary) model. This research method uses a combination of the RFM model and clustering. RFM is used as a description of customer behavior in conducting transactions. Clustering is a process that is widely used and is designed to categorize data. Clustering uses the K-Means Algorithm to determine the number of clusters using the Elbow and Silhouette methods. The application of RFM analysis and the K-Means resulted in two customer segments, namely potential customers and non-potential customers. Potential customers have the characteristics of frequent transactions and also large expenses. Non-potential customers have the characteristics of infrequent transactions and also standard expensesKeywords:  Customer Segmentation, RFM Model, K-Means Clustering
