Detecting window line using an improved stacked hourglass network based on new real-world building façade dataset
Authors: Yang Fan , Zhang Yiding , Jiao Donglai , Xu Ke , Wang Dajiang , Wang Xiangyuan
Published: May 2023

Three-dimensional (3D) city modeling is an essential component of 3D geoscience modeling, and window detection of building facades plays a crucial role in 3D city modeling. Windows can serve as structural priors for rapid building reconstruction. In this article, we propose a framework for detecting window lines. The framework consists of two parts: an improved stacked hourglass network and a point–line extraction module. This framework can output vectorized window wireframes from building facade images. Besides, our method is end-to-end trainable, and the vectorized window wireframe consists of point–line structures. The point–line structure contains both semantic and geometric information. Additionally, we propose a new dataset of real-world building facades for window-line detection. Our experimental results demonstrate that our proposed method has superior efficiency, accuracy, and applicability in window-line detection compared to existing line detection algorithms. Moreover, our proposed method presents a new idea for deep learning methods in window detection and other application scenarios in current 3D geoscience modeling.

Mixed sedimentation is mainly a phenomenon by which siliciclastic and carbonate are mixed under a similar sedimentary environment. The study of the composition of mixed rock can reflect the sedimentary environment. The mixed sediments of the Canglangpu formation in the eastern Sichuan basin are widely developed and exhibit well exploration prospects. In this study, a classification diagram of mixed sediments suitable for the Canglangpu formation was proposed by combining lithologic characteristics with logging data. Based on the observations of typical outcrop profiles, the identification of thin sections, and drilling and geological logging data, a model was established to identify the electrical responses of the mixed sedimentary rocks in the study area. The results show that (1) the Canglangpu formation can be vertically divided into two complete transgression-regression cycles with the lower part mainly consisting of sedimentary carbonate diamictite and the upper part principally composed of clastic diamictite; (2) mixed sediments in the Canglangpu formation can be divided into six classes, namely carbonate sandstone, argillaceous sandstone, sandy carbonate rock, argillaceous carbonate rock, sandy mudstone, and Carbonate mudstone; (3) the sedimentary environment of the Canglangpu formation be divided into (a) mixed sediments in the shore, which include mixed lagoon and mixed tidal flat, (b) mixed sediments in the shallow marine shelf, which includes mixed beach bar, terrigenous detrital mixed shelf, and carbonate mixed shelf; (4) a mixed shore-mixed shelf sedimentary model has been established; it says that the mixed sediments show obvious characteristics of ring-like development around underwater paleo-heights. The formation mechanism of mixed sedimentation in the eastern Sichuan basin is mainly controlled by the change of sedimentary facies belt, and the development intensity is mainly influenced by early tectonic movement and sea-level change.

Published: May 2023

The purpose of this scoping review was to assess the state of the literature concerning the experiences of new PhD-prepared tenure-track faculty, with a keen interest in nursing faculty. Effective recruitment and retention strategies for new nursing academic faculty need to be found and implemented. A literature review based on Arksey and O’Malley’s five-stage framework for scoping reviews was undertaken. Using the PRISMA protocol, a systematic literature search was conducted in seven databases of studies published in English. Based upon inclusion criteria and relevance, 13 studies out of 90 papers were included in this study. Themes identified from the studies were transitioning to academia, developing a research program, balancing work and life, and perceived inequity. The research was predominately American and Canadian based. Several gaps in the literature were identified. Further research is critical to make recommendations to key stakeholders for recruitment and retention strategies.
AKM Effects for German Labour Market Data from 1985 to 2021
Authors: Lochner Benjamin , Wolter Stefanie , Seth Stefan
Published: May 2023

This article describes the processing and accessibility of the person and establishment fixed wage effects in German administrative data. These effects have been estimated following the approach of Abowd, J., Kramarz, F., and Margolis, D. (1999. High wage workers and high wage firms. Econometrica 67: 251–333) and Card, D., Heining, J., and Kline, P. (2013. Workplace heterogeneity and the rise of West German wage inequality. Q. J. Econ. 128: 967–1015). They can be linked to most of the available administrative datasets provided by the Research Data Center (FDZ) of the German Federal Employment Agency at the Institute for Employment Research (IAB). They are available for different time intervals from 1985 until 2021. These effects have been used in numerous articles that deal with the contributions of workers and establishments to earnings inequality.

Published: May 2023

The demand on broadband near-infrared photodetections with high responsivity is becoming increasingly eminent; however its realization remains a significant technological challenge. Here we design, fabricate, and characterize a broadband Ge photodetector (1000–1600 nm), composed of densely packed 230-nm-thick Ge disks of different diameters (255 nm, 320 nm, and 500 nm), placed on top of a 105-nm-thin Ge layer. Using experimentally measured and calculated transmission and absorption spectra, we demonstrate that the absorption and detector responsivity are increased by nearly 2 orders of magnitude, compared to the unstructured Ge photodetector, due to the excitation of magnetic dipole resonances in Ge disks, while preserving a relatively low dark current. Our approach is simple and can be easily adapted to other semiconductor material platforms and operation wavelengths to enable performance improvements of broadband photodetector devices.

Bu çalışmada ambalajsız olarak satışa sunulan ve yöresel bir peynir çeşidi olan Hatay peynirinde uygun ambalaj malzemesi ve teknolojilerinin kullanımı ile daha kaliteli ve uzun raf ömrüne sahip bir ürün elde edilmesi hedeflenmiştir. Bu nedenle dilimlenmiş peynir örnekleri modifiye atmosfer (%50 CO2 ve %50 N2), hava (%21 O2 ve %79 N2) ve vakum altında üç farklı geçirgenlikte ambalaj malzemeleri (Koekstrude PA/PE, OPET/OPA/CPP ve PP/PA/EVOH/PE) ile ambalajlanmış ve 4°C’de 60 gün süreyle depolanmıştır. Depolama süresince tepe boşluğu gaz oranları (%O2 ve CO2), fizikokimyasal ve duyusal analizler yapılmıştır. Depolama süresince ambalajlı uygulamalarda ürün beyazlığı ve tekstür daha iyi korunmuş, duyusal nitelikler kabul edilebilir bulunmuştur. Tüm uygulamaların titrasyon asitliği ve TBARS değerleri artmış ve pH değerleri azalmıştır. Ancak depolama boyunca en iyi sonuçlar gaz geçirgenliği en düşük olan PP/PA/EVOH/PE’de vakum uygulamasında ve yüksek karbondioksitli MAP uygulamalarında alınmıştır. Sonuç olarak, ambalajsız üründe raf ömrü 5 gün, ambalajlı peynirlerde raf ömrü 60 gün olarak önerilmektedir.

Virus Corona (covid-19) saat ini masih menyebar luas sehingga menyebabkan pemerintah menerapkan kebijakan stay at home dan social distancing kepada seluruh masyarakat termasuk para mahasiswa untuk belajar di rumah. Kebijakan tersebut tentu berdampak pada berbagai aspek kehidupan mulai dari ekonomi, pendidikan, hingga kesejahteraan psikologis masyarakat. Salah satu permasalahan psikologis yang muncul adalah kesepian. Menurut beberapa literatur psikologi, ketahanan yang baik dibutuhkan untuk menghadapi kondisi yang sulit dan mengubahnya menjadi suatu hal yang wajar untuk diatasi. Inilah yang disebut sebagai resiliensi. Penelitian ini bertujuan untuk mengetahui hubungan antara resiliensi dan kesepian pada mahasiswa selama masa social distancing pandemi Covid-19. Survei online dilakukan dengan menggunakan dua skala, yaitu skala kesepian dan skala resiliensi. Teknik yang digunakan dalam penelitian ini adalah teknik convenience sampling. Subjek yang terlibat adalah sebanyak 355 mahasiswa. Berdasarkan hasil analisis data yang dilakukan dengan teknik korelasi Rank Spearman, diperoleh koefisien korelasi antar variabel sebesar -0,558 dengan nilai signifikansi sebesar 0,000 sehingga p0,01. Hal ini menunjukkan bahwa ada hubungan negatif yang signifikan antara resiliensi dan kesepian pada mahasiswa selama masa social distancing yang mereka jalani. Maknanya adalah semakin tinggi resiliensi maka akan semakin rendah kesepian pada mahasiswa di masa social distancing pandemi Covid-19, dan begitupun sebaliknya.The corona virus (covid-19) is currently still widespread, its causing the government has implemented to stay at home and social distancing for the entire community including students to study at home.

The use of efficient and environmentally friendly methods for electricity generation is one of the main concerns in the field of energy. The advantages and disadvantages of wave energy power plants are well-known and continuously researched. There are many approaches and methods for converting wave energy into electrical energy, each with its own advantages and disadvantages, designed for different converter constructions and utilizing various approaches. This article presents a simple converter scheme that converts the energy of cylindrical buoy oscillations into electrical energy. The aim of this work is to develop a methodology for calculating the energy characteristics of this wave energy converter, consisting of a cylindrical buoy, a pulley, and a magneto-electric generator, using the average energy indicators of the generator. The proposed converter scheme utilizes a single cylindrical buoy and a three-phase generator with resistors as the electricity consumer. The sea surface oscillation is represented by a sine wave with higher harmonics. The balance equation of forces acting on the buoy is formulated, taking into account the ratio of the moment on the rotor to its speed. An iterative calculation is used to determine the optimal rotor speed to maximize electricity consumption power. To establish the resistor's resistance, the steady-state operation modes of the generator and the average optimal rotor speed over the period of the sea wave are used. The generator is then modeled with an optimal resistor resistance and a specified variable rotor speed over the wave period. The energy absorbed by a single buoy, with a wave amplitude of 1 meter and a period of 10 seconds, is studied. Ref. 16, fig. 10.

Bixa orellana L. is widely used as a dye, and other properties are still little studied, especially in relation to leaves. This article evaluates how drying B. orellana L. influences the properties of essential oils (EOs) extracted from their leaves. The collected plant material was submitted to convective air-drying oven at temperatures of 35, 45 and 55 °C. Chemical profiles were determined by Gas Chromatography-Mass Spectrometry (GC-MS). Mathematical models were applied to represent the drying process and statistical analysis performed using Statistica 10 software. The EO's were obtained through the hydrodistillation technique with verification of physicochemical properties and antimicrobial activity by the Disc Diffusion Method. For the toxicity test, the bioassay was applied to Artemia salina. Through the results obtained it was possible to determine that the mathematical model of Verma was the one that best fitted the experimental data. Significant differences in the properties of EO's were observed. The temperature of 45 °C allowed obtaining the best EO yield, still presenting the most efficient antimicrobial activity. This study states through the activities analyzed that the drying temperature influences the physicochemical and biological properties of the EO's, thus requiring studies such as this one that evaluate the best mathematical model to predict drying as well as the specific temperatures that influence the properties of the product obtained.

Published: May 2023

Este estudio investiga el conocimiento existente de la COVID-19 en ambos sexos y propone una práctica para prevenir la COVID-19. Se realizó un estudio transversal con una encuesta en línea recopilando datos en diferentes regiones de Colombia, a través de un cuestionario validado estructurado y de diseño propio basado en el asesoramiento público general de la Organización Mundial de la Salud (OMS) sobre la prevención de la COVID-19. Este estudio ha empleado la técnica de muestreo de bola de nieve, y contó con 445 participantes (46,5% hombres y 53,5% mujeres). Se identificó que las mujeres no solo tienen un mejor conocimiento, sino que su comportamiento en la práctica es mucho mejor que sus contrapartes masculinas. Aunque los resultados entre hombres y mujeres son muy similares, la pregunta de quedarse en casa es bastante concluyente a favor de las mujeres, quienes son más responsables. Finalmente, el estudio demuestra que las mujeres corren menos riesgo en comparación con los hombres, porque estas tienen mejores prácticas de prevención, como lo indican las estadísticas. Este estudio destaca aún más la idea de que las mujeres son menos propicias para contraer la infección de covid-19 debido a su mejor comportamiento de práctica que los hombres.

Introdução: pela primeira vez, o processo eletroanalítico da detecção da ergina (LSA) sobre um elétrodo, modificado por um derivado triazólico, dopado pelo íon amavadina, tem sido descrito teoricamente. Métodos: o modelo matemático, correspondente ao desempenho do sensor, tem sido desenvolvido e analisado do ponto de vista da teoria de estabilidade linear. Foi mostrado que a amavadina pode servir de modificador eficiente para a detecção eletroanalítica da ergina. Outrossim, a presença de um material orgânico no modificador reforça a capacidade da ergina de polimerizar-se, formando um compósito polimérico. Resultados: os comportamentos oscilatório e monotônico são mais prováveis que no caso mais comum, haja vista a formação-deformação de compostos iônicos aquando da detecção eletroanalítica.

Published: May 2023

El aumento de la resistencia bacteriana a  los antibióticos comúnmente empleados para el tratamiento de infecciones cutáneas, pone en manifiesto la necesidad de  encontrar medicamentos alternativos y eficaces, capaces de contrarrestar este problema de salud que no sólo implica una región, sino que  se ha convertido en un problema de salud mundial. Se ha demostrado que un novedoso complejo a base de tinidazol y cobre ([Cu(tnz)2(NO3)2]) posee buena actividad antimicrobiana, sin embargo, para que pueda emplearse como una alternativa para el uso tópico, debe poseer las características necesarias para que  pueda ser incorporado, en una formulación que permita su aplicación. Teniendo en cuenta que las formas farmacéuticas semisólidas constituyen el grupo más empleado dentro de las formulaciones dermatológicas;   se elaboraron dos tipos formulaciones una tipo crema y otra crema-gel, con el fin de verificar en cuál de ellas incorpora convenientemente el complejo [Cu(tnz)2(NO3)2]. Para ambas formulaciones se determinaron las propiedades organolépticas, pH, área de extensibilidad, viscosidad, y tamaño de partícula,. Los resultados obtenidos evidencian las ventajas de la formulación tipo crema frente a la crema-gel.
Septo-optic dysplasia/ Morsier’s syndrome; a disease to be suspected
Authors: Sánchez Mellado A. , Montoro Moreno R. , Lacorzana J.
Published: May 2023

Septo-optic dysplasia (SOD) or Morsier syndrome is a rare congenital malformation of infantile neurodevelopment with systemic anatomical and functional involvement. It is characterized by optic nerve hypoplasia, midline brain malformation, and hypothalamic-pituitary axis hypoplasia. The spectrum of clinical manifestations is very wide, from ophthalmological problems to endocrinological disorders that determine the severity and prognosis of these patients. The diagnosis is fundamentally clinical, based on an anamnesis and systematic clinical examination, supported by complementary tests for the study of hormonal deficits and imaging tests that objectify structural malformations. SOD has no cure; however, close follow-up focused on improving comorbidities through hormone replacement, neuropsychological support, and visual correction is necessary to improve the patient’s quality of life. Its low incidence and the breadth of forms of presentation require the knowledge and multidisciplinary approach of specialists in Pediatrics, Neurology, Endocrinology and Ophthalmology, among others. We present a descriptive case of this disease and its management.

Published: May 2023

Introduction: Although the main symptomatology of COVID19 is respiratory, many patients present digestive symptoms, which can be used to guide earlier diagnosis, anticipating isolation measures and the establishment of treatment. Given that older subjects present more severe forms of COVID 19, even compromising their lives, these measures are more relevant among the elderly population.
Methods: In the present study, 147 cases with SarsCov-2 infection identified in a nursing home during March and April 2020 were analyzed.
Aims: To analyze cases with SarsCov-2 infection identified in a nursing home, as well as to describe the clinical presentation of symptoms and the evolution of the condition in these patients. The secondary objective is to demonstrate the importance of digestive symptoms in COVID-19.
Results: In 71 patients (48.3%) data of COVID-19 infection were detected by PCR and/or rapid test for specific antibodies. 39.4% were asymptomatic. Of the positive patients, 72.1% were women and the mean age was 80.8 years (SD=16.7). The most frequent symptom was diarrhea (48.8%), followed by cough (41.9%) and fever (39.5%). Diarrhea was detected on the first day of illness in 90.4%. In 33.3% it was associated with other symptoms and in 16.6% it was isolated. The mean duration of the symptoms was 11.7 days. Hospital admission was required in 30.2% of patients. 16.2% died due to respiratory complications or sepsis.
Conclusions: Gastrointestinal symptoms may be frequent in COVID-19 infection and may even be the first manifestation of the disease. This group of patients had a lower proportion of complications and case fatality than usual. However, the role of digestive symptoms in COVID-19 infection needs to be verified with larger studies.

Authors: Calvo Bernal B. , López Rus M.A.
Published: May 2023

Nowadays, the infections due to carbapenem-resistant microorganism represent a global public health issue; the microorganisms most frequently involved are the gram-negative bacteria. This infections pose a major threat because of their elevated mortality, the lack of appropiate antibiotics and its rapid spread arround the world. The emergence of carbapenemases, which are a type of enzimes that hydrolize carbapenems, is the resistance mecanism more frequently involved. The aim of this literature review is to analyse the epidemiology arround the world and ,overall, in Europe; as well as the microbiological aspects of the carbapenem restistant bateria: carbapenemases can be classified into different types and are detected by several laboratory methods as well as its detection methods in laboratory. All this are key aspects and have a great impact on the clinical management of these infections.

DIGNIDADE DA PESSOA HUMANA E O AUTORITARISMO CRESCENTE NO BRASIL
Authors: Nonato Eunice Maria Nazarethe , Campos Renata Bernardes Faria , Nascimento Geraldo Barbosa , Cardozo Schinyder Exupery
Published: May 2023

O objetivo deste trabalho é refletir sobre o conceito da dignidade da pessoa humana. Isto feito, procuramos analisá-lo tendo em vista o estágio atual dos direitos e garantias fundamentais no Brasil. A metodologia utilizada é do tipo qualitativa, baseada em pesquisa bibliográfica, bem como em recentes casos práticos acerca de direitos e garantias fundamentais. Num primeiro momento, faz-se uma abordagem da conceituação histórica da dignidade da pessoa humana, a começar da sua origem no pensamento filosófico clássico e ideário judaico-cristão. No momento seguinte, analisa-se a ordem em que a dignidade da pessoa humana ocupa na Constituição Brasileira de 1988, confrontando-a com o tratamento recebido em casos práticos ocorridos no Brasil no ano de 2019. O estudo mostra-se relevante porque alarga a compreensão do princípio da dignidade da pessoa, contribuindo para o enriquecimento científico aos operadores do direito, em eventual interpretação jurídica e realização mais adequada da justiça. A pesquisa constatou que o conceito de dignidade da pessoa humana não é fixo, carregando um sentido impreciso, vago, em razão mesmo do pluralismo e diversidade de valores que se manifestam nas sociedades estudadas. Quando submetido à ótica de crescentes casos de autoritarismo no Estado (Pós) Democrático de Direito, percebe-se um estreitamento de sua pertinência e abrangência para com direitos fundamentais.   Tal constatação sugere a tarefa permanente na construção de uma fundamentação que legitime a noção de dignidade da pessoa humana, no mundo pós-moderno, que possa servir de referencial à sua concretização, sobretudo para garantia dos direitos fundamentais com limites rígidos à atuação estatal.
HOMESCHOOLING: UMA PROPOSTA DO ESTADO NEOLIBERAL PARA A EDUCAÇÃO BRASILEIRA
Authors: Almeida Emanoel Rodrigues , Cardoso Eugênio Alves , Da Silva Clemildo Anacleto
Published: May 2023

O Estado capitalista foi moldado a partir de crises econômicas recorrentes, que resultou nas modificações das relações de trabalho e na estrutura do Estado. O Estado neoliberal é a forma mais avançada de Estado capitalista e se tornou hegemônico nas últimas décadas do século XX, a partir da necessidade de reestruturação do sistema, abalado pela crise de 1970. Essa reestruturação demandou uma nova forma de organização do Estado, do trabalho e da educação, que foram flexibilizados, atendendo às novas demandas do capital. Seguindo a linha do neoliberalismo, a educação aparece como mercadoria que deve ser submetida ao poder do mercado, de preferência ofertada por instituições privadas. É neste contexto, no Brasil, que emergem fortemente as ideias do homeschooling, apoiada na ascensão do neoconservadorismo. No atual contexto, este estudo se justifica a partir da necessidade de se debater a proposta de educação domiciliar que avança no senado, incorrendo no risco de pôr em risco a educação pública.  O objetivo geral é analisar a relação do Estado neoliberal com a educação, enfatizando o cenário brasileiro e o projeto de homeschooling que tramita no senado federal. É um estudo de caráter qualitativo, que usou como ferramenta de obtenção de dados pesquisas bibliográficas em livros, artigos de revista e jornais etc. O método de pesquisa ancora-se no materialismo histórico dialético. Nos resultados e discussões apontamos que foi possível compreender que o neoliberalismo entende a educação como parte do projeto de perpetuação da sociedade capitalista, por isso tem interesse em mantê-la sob controle, e se possível, privatizá-la, sendo o Homeschooling o provável passo inicial para o projeto de privatização.
EDUCAÇÃO SEXUAL NA ESCOLA: UM DIÁLOGO SOBRE DIREITOS DA COMUNIDADE LGBTQIAPN+
Authors: Neto José Olímpio Ferreira , Barbosa Fabiano Geraldo
Published: May 2023

Este artigo tem o objetivo de apresentar reflexões sobre fragmentos de uma projeto pedagógico de educação sexual na escola que propôs um diálogo sobre direitos da Comunidade LGBTQIAPN+. O projeto foi aplicado em turmas do Ensino Fundamental de uma escola pública municipal de Fortaleza-CE, com fundamento numa educação para os direitos humanos. Diante da visibilidade da população LGBTQIAPN+, no contexto escolar, foi pensado no desenvolvimento de uma proposta pedagógica que desse voz aos jovens dessa comunidade para que seus direitos sejam respeitados. Então, a partir da concepção de uma Sequência Didática, foram desenvolvidas atividades, nas quais os/as participantes colaboraram para a elaboração de uma cartilha sobre Direitos Homoafetivos e de Gênero, a partir de metodologia qualitativa com exposição de conteúdos, pesquisa, roda de diálogos, sugestões e dúvidas, numa perspectiva extensiva, inclusiva e reflexiva, reconhecendo os direitos humanos e sociais como parte inerente à emancipação humana. Como resultados iniciais, foi notório perceber a participação ativa dos jovens na luta por direitos exercitando a participação popular e efetivando o princípio da dignidade da pessoa humana. É possível afirmar a necessidade da constituição de espaços na rotina escolar que possam dar voz à diversidade para que haja uma participação mais ampla nas decisões e efetivação de direitos, formando cidadãos emancipados que modifiquem a realidade. O projeto apresentado pode ser caracterizado como atividade educativa emancipadora por proporcionar o desenvolvimento do sujeito-histórico capaz de promover uma nova forma de sociabilidade que se contrapõeao capital.
Using Brazilian Health Surveys 2013 and 2019 for a nationwide diabetes risk assessment
Authors: Silva Marcelo Moreira da , Menezes Mario Olímpio de
Published: May 2023

Brazil had, in 2021, almost 15.7 million people with diabetes (type 1 and 2). In this work, using the Pesquisa Nacional de Saúde (PNS) 2013 and 2019, the diabetes risk for the entire population covered by those surveys, with 18 years and older, was assessed applying the American Diabetes Association Risk Test. Only one question from that test, regarding relatives with diabetes, could not be answered from the PNS questionnaires. After applying the test to both PNS 2013 and 2019, 15.9% and 19.0% of the population with 18+ years was found to be at risk of developing diabetes, representing about 23 and 28 million people, respectively. Those with 65+ years were found to be more at risk, increasing from 42.3% in 2013 to 46.0% in 2019. A good result came from those with BMI > 30, whose percentage at risk dropped from 47.9% in 2013 to 42.5% in 2019. Brazilian states with the biggest risk increase were Tocantins, Mato Grosso do Sul, Piauí and Bahia, all with more than 4pp, while ten states had increases bigger than 3pp. The results obtained in this work corroborate recent findings in diabetes prevalence studies and also reinforce the great importance of such nationwide health survey, as it represent an invaluable resource to public health policies.
OPTIMIZATION OF THE GEOMETRIC PROFILE OF A CRESCENT ORIFICE
Authors: Panda Santosh Kumar , Nepak Sunil Kumar
Published: May 2023

An orifice is a fundamental flow measuring and control device that works on the pressure difference (Δp) concept in single and multiphase flows. Flow measurement is critical in the petroleum, energy, laboratory, chemical, nuclear, mining, processing, and food industries for flow regulation. Circular orifice flow measurement contains errors in flow measurement. Various orifice shapes used for different applications better reduce errors and uncertainty. The present work carries a numerical analysis based on computational fluid dynamics–based software (Ansys Inc.) to determine the coefficient of discharge and pressure drop for a crescent orifice. The geometric parameters considered to be variable for the investigations are Reynolds number (Re), orifice thickness (space ratio as τ), and area ratio (as σ). Air is considered flowing fluid as a single fluid. The geometric profiles also change as the inner and outer curvature for optimizing design according to the flow profile and determination of the coefficient of discharge. The outcome will aid in the design and control of the flow measuring instrument in the relevant flow field for the optimal design of the crescent orifice.

Published: May 2023

In December 2022, a team of authors prepared and published in the English version the monograph Nomenclature and rank correlation of higher taxa of eukaryotes, dedicated to a review of higher taxa of eukaryotes and solving the problem of their rank correlation. The introductory part of the work shows significant milestones in the history of eukaryotic megasystematics, whereas the methodological part discusses the principles and approaches to the nomenclature of the higher taxa of this domain. The authors carried out a revision of the system of eukaryotic organisms with references to the original descriptions of the corresponding taxa, considered the trends in the transformation of the system, and discussed issues of its practical application. The book contains descriptions of the subdomain Obimoda, the kingdom Crumalia, and the phyla Mantamonadea, Rigifilidea, and Collodictyonidea. The monograph crowned with a retrospective summary of the main eukaryotic systems published in the period 19252022 and an extensive list of papers on megasystematics and microbiology of eukaryotes. The present review is devoted to the evaluation of this theoretically and practically important work.
