Reverberation and its Binaural Reproduction: The Trade-off between Computational Efficiency and Perceived Quality
Authors: Engel Isaac , Picinali Lorenzo
Published: January 2022

Accurately rendering reverberation is critical to produce realistic binaural audio, particularly in augmented reality applications where virtual objects must blend in seamlessly with real ones. However, rigorously simulating sound waves interacting with the auralised space can be computationally costly, sometimes to the point of being unfeasible in real time applications on resource-limited mobile platforms. Luckily, knowledge of auditory perception can be leveraged to make computational savings without compromising quality. This chapter reviews different approaches and methods for rendering binaural reverberation efficiently, focusing specifically on Ambisonics-based techniques aimed at reducing the spatial resolution of late reverberation components. Potential future research directions in this area are also discussed.
Periodic Acoustic Black Holes to Mitigate Sound Radiation from Cylindrical Structures
Authors: Deng Jie , Gao Nansha
Published: January 2022

Acoustic black holes (ABHs) achieved by progressively diminishing structural thickness have been proved a very efficient approach for wideband vibration reduction, sound suppression, energy harvesting, and wave manipulation. In this chapter, the focus is placed on mitigating the sound emitted from cylindrical shells with embedded ABHs. In the applications of aeronautics, astronautics, and underwater vehicles, cylindrical shells are very common yet the vibroacoustic problems in such structures are very challenging. Even the researches on ABHs for straight beams and flat plates are boosting in recent years, the ABH effect is unclear for curved structures thus it deserves further investigations to push forward their applications. Since cylindrical shells are usually long in, for example, airplanes and rockets, periodic ABHs are designed to alleviate the acoustic emission from them. The Gaussian expansion method (GEM) is employed to recover the vibration field on the cylinder and, based on that, the sound radiation model is developed to determine the emitted sound power level (SWL). The band gaps (BGs) are shown for infinite periodic ABH shells, followed by the vibroacoustic level for a finite periodic shell. Particularly, axial stiffeners are introduced and the influences of their quantity and width are carried out.

Authors: Fotopoulou Maria , Rakopoulos Dimitrios , Stergiopoulos Fotis , Voutetakis Spyros
Published: January 2022

The majority of Medium Voltage (MV) and Low Voltage (LV) power systems are based on and operate using Alternating Current (AC) infrastructures. Yet, modern energy market needs, which promote more decentralized concepts with a high Renewable Energy Sources (RES) penetration rate and storage integration, bring Direct Current (DC) to the forefront. In this sense, AC/DC hybrid smart microgrids constitute a newly-introduced research field with a variety of potential applications that combine the benefits of both AC and DC systems. The purpose of this chapter is to review the advantages and disadvantages of AC/DC hybrid grids and analyze potential applications that would benefit from such infrastructures. Also, the most significant efforts and requirements for the constitution of a solid regulatory framework for AC/DC hybrid grids are presented, to pave the way towards their wider adoption by the market.

Authors: Aprovitola Andrea , Medugno Fabrizio , Pezzella Giuseppe , Iuspa Luigi , Viviani Antonio
Published: January 2022

In the present work, a feasibility study of a manned Mars entry, descent, and landing mission, performed with a lifting vehicle, is analyzed. Mars entry challenges relate to different atmosphere models; consequently, the effective landing capability of a winged configuration is discussed. An entry trajectory study in the Martian atmosphere assuming both a planar and non-planar three degree-of-freedom model is performed. Peak heat rates and time-integrated heat loads during the descent are computed verifying the entry corridor. It is shown that prescribed aerodynamic performances can be modulated explicitly by varying angle of attack and implicitly with bank-angle modulation. Finally, the resulting trajectory is discussed in terms of g-loads, total range performances, and integral heat load absorbed, in the perspective of future manned exploration missions.
Diagnosis of Amyloidosis: From History to Current Tools
Authors: Juneja Richa , Dange Prasad , Arora Rahul
Published: January 2022

The term amyloid encompasses a large variety of misfolded proteins with varying amino acids unified by the antiparallel beta-pleated sheet configuration and characteristic Congo red staining. The etiology of these proteins is equally varied, ranging from neoplastic plasma cell disorder, hereditary causes to inflammatory disorders. The protean clinical manifestation makes a high index of clinical suspicion the first crucial step in the diagnosis. A battery of investigations needs to be carried out for a complete diagnosis of amyloidosis and its underlying etiology. Biopsy with Congo red staining constitutes the most important modality for confirmation of amyloid. For further testing, varying modalities with increasing complexity, such as immunohistochemistry, electron microscopy, and mass spectrometry, need to be employed. We discuss, in the course of the current chapter, this fascinating protein from a clinical diagnosis perspective. The requisite investigations are also discussed in detail.
Production Systems Performance Optimization through Human/Machine Collaboration
Authors: Dossou Paul-Eric , Verdier Valentin , Ogor Alan
Published: January 2022

The growth of enterprises is a constant source of research and development of new technologies. Indeed, to stand out from the competition and optimize their production, companies are moving toward the centralization of information and the implementation of machines. This dynamic requires a significant investment in terms of organization and research. Industry 4.0 is therefore at the heart of this reflection, as shown in the literature. It brings together many technologies, such as Artificial Intelligence (AI), the Internet of Things (IoT), and Big Data. This chapter focuses on company performance optimization through a sustainable Industry 4.0 framework involving methodologies such as lean manufacturing and DMAIC, new technologies as robotics, in addition to social, societal, and environmental transformations. This chapter will present robotic displacement solutions adapted to the industrial environment for improving production systems performance. Solutions for human-machine interaction problems such as human-machine interface or flexibility 4.0 will be shown.
Complications of Ulcerative Colitis in Children
Authors: Wiecek Sabina
Published: January 2022

Inflammatory bowel disease is a group of chronic disorders of the gastrointestinal tract, including Lesniowski-Crohn disease, ulcerative colitis, and indeterminate colitis. The most frequently occurring symptoms in patients with IBD, including ulcerative colitis, involve abdominal discomfort, recurring and often bloody diarrhoea, weight loss, and the resulting anaemia and/or cachexia. Extraintestinal manifestations of ulcerative colitis may precede the diagnosis of inflammatory bowel disease, they may also occur during remission (pyoderma gangrenosum, uveitis, spondylitis, and PSC) or accompany an exacerbation of the disease (erythema nodosum, episcleritis, aphthae, and some forms of peripheral spondyloarthritis). This study focuses on the most common extraintestinal manifestations and complications in ulcerative colitis in paediatric patients.
Hemodynamic Alterations in Multiple Sclerosis
Authors: Seda Artis Aise
Published: January 2022

Multiple Sclerosis is an autoimmune disease of the central nervous system. It is a demyelinating and neurodegenerative condition, however, changes in the vasculature can occur and play a role in the pathophysiology. Cardiac and vascular risk factors contribute to the disease severity. Understanding the occurring hemodynamic changes may potentially lead to improved diagnosis, better patient management, and prevention of disease progression. This paper discusses the hemodynamic impairment in multiple sclerosis focusing on both the cerebral and cervical regions and presents an up-to-date review of the literature.
Bats in Folklore and Culture: A Review of Historical Perceptions around the World
Authors: Sieradzki Alan , Mikkola Heimo
Published: January 2022

Belief systems of people have always been closely related to animals, which are symbolized in traditional narratives. Sociocultural definitions of animals as “good or evil” have persisted throughout the history of human beings. In the West, bats are often perceived as evil spirits, Vampires, and harbingers of death, while some cultures across the Asia-Pacific region associate bats with good fortune. Here, we review documented narratives and surveys from around the world and our ethnographic observations from Europe to analyze beliefs associated with bats. We explore the role that bats play in traditional narratives and the likely reasons for their salience, including their connections with the extraordinary and supernatural. Finally, we discuss shortly the need of education to change attitudes toward bats. In North America, education has had some effect as more people have started to understand how useful bats truly are and how few cases of bat-born rabies transmission to humans there have been in the United States and Canada. It remains to be seen, however, how effectively the further education efforts could halt or even reverse the decline of the bats around the world. It is also noted that bat tourism has a potential to conserve bat populations while providing social and economic benefits to local people in host communities.
Design and Simulation of Low-Cost Microgrid Controller in Off-Grid Remote Areas
Authors: Bangtit Tapparit
Published: January 2022

This study presents the microgrid controller with an energy management strategy for an off-grid microgrid, consisting of an energy storage system (ESS), photovoltaic system (PV), micro-hydro, and diesel generator. The aim is to investigate the improved electrical distribution and off-grid operation in remote areas. The off-grid microgrid model and the control algorithms developed using MATLAB Simulink and State flow. The energy management system is focusing on the state of charge of the energy storage system. The microgrid controller controls the operation mode and power generation from the distributed generations’ local controller, i.e., PV, micro-hydro, and diesel. It also controls the smart meters of the loads to be connected or disconnected to the microgrid. The simulation results show that the proposed microgrid control can control the target off-grid microgrid in given possible scenarios. The off-grid microgrid managed to meet the energy demand with the lowest power outage and the diesel generator operation’s lowest cost.

Published: January 2022

The field of brachial plexus surgery has undergone dramatic changes in the past 40 years. Most of these have been incremental in nature. We have seen increased use of nerve grafts and nerve transfers. We have seen the introduction of robotic limb replacements for the most severe flail limbs where surgical intervention has failed. In some cases, we have seen an increase in the use of computer simulation and virtual reality to train surgeons to plan and execute surgeries. More recently, we have seen the introduction of technologies derived from regenerative medicine research.
Understanding the Responses, Mechanism and Development of Salinity Stress Tolerant Cultivars in Rice
Authors: Nagarajan Sathees , Varatharajan Nirubana , Vellaichamy Gandhimeyyan Renganathan
Published: January 2022

Rice is the most important staple food crop of much of the world’s population. Production and consumption of rice is higher in Asia but adverse environmental conditions critically threaten the rice production. Soil salinity has been a key abiotic constraint affecting the crop production by reducing growth, development and yield of the plant. Rice is highly sensitive to salinity specifically at the early vegetative and late reproductive stages. Therefore, studying the responses of crop at the morphological, physiological, biochemical and molecular level is an effective strategy. Understanding the mechanisms behind the salinity such as osmotic stress and osmolytes, ion exclusion, inclusion and compartmentation, antioxidant response and hormonal regulation. Different screening strategies such as phenotypic and genotypic screening for rice under salinity and select the salt tolerant lines. Using the conventional and molecular breeding approaches is a prerequisite for its effective management and to develop salt tolerant cultivars in rice.
San Juan de la Cruz and the Cántico Espiritual
Authors: Howe Elizabeth Theresa ,   Marquette University Press
Published: January 2022

The predominant imagery of progress in western mystical writing usually describes some form of ascent. The Subida del monte Carmelo by San Juan de la Cruz certainly suggests the notion in Spanish mystical writing. While San Juan proffers ascent (subida) in the title of the commentary on “En una noche oscura,” the poem proper does not present a sense of verticality at all but, rather, an essentially horizontal passage from the “casa sosegada” to (re)union with the Lover in a static apotheosis described in the final strophes. Similarly, a paradoxical presentation of movement appears in the Cántico espiritual. This article considers San Juan’s use of verbs of movement, especially within the Cántico espiritual, as metaphors for the underlying mystical message he ascribes to his poem. It also demonstrates the presence of the same extended metaphor in other poems of his, including “En una noche oscura” and the “Llama de amor viva.
War as Pornography
Authors: Hazo Samuel ,   Marquette University Press
Published: January 2022

Pornography has been defined as sex separated from personality. In other words, life’s deepest need to express desire and affection and perpetuate the species is reduced to appetite and the satisfaction of appetite. War in many ways does the same. It depersonalizes killing by pitting stranger against stranger—uniformed or otherwise. Fatalities are reduced to numbers. Such killings are dignified by slogans (“Vietnamizing the Vietnamese” or “Operation Iraqi Freedom”),. Preparing troops for the killings in war is everything from oratory to close order drill, parades and honors. Denis de Rougemont in LOVE IIN THE WESTERN WORLD has even traced this to the legend of Tristan and Isolde in which Tristan chooses a military life to define his manhood after leaving Isolde. All of these manifestation and pretenses gloss over the brutality of war just as films, photographs and other promotions disguise pornography as mere excitement.
Um testemunho do cárcere: o caso Sobrevivente André Du Rap (do massacre do Carandiru)
Authors: Martins Aulus , Mattos Isadora
Published: January 2022

O presente artigo tem por objetivo analisar a chamada “Nova literatura de cárcere” brasileira através da obra Sobrevivente André Du Rap (do massacre do Carandiru) (2002), do jornalista Bruno Zeni a partir do relato de André Du Rap. Tal tendência da literatura nacional apresenta-se como uma quebra do paradigma de representação da experiência prisional ao trazer para o centro da discussão o relato de um preso comum, em contraposição aos relatos de presos políticos, até então dominantes na categoria. A análise procurou verificar a pertinência da aparente familiaridade da obra com o testimonio, corrente dominante de literatura de testemunho na América Latina durante a segunda metade do século XX.
A função do ensino de literatura: ponto de convergência e de ramificação de perspectivas
Authors: Martins Bárbara Machado
Published: January 2022

Apresentamos neste artigo uma discussão a respeito da função do ensino da literatura nas escolas. Dado que a extenuação dessa temática seria intangível, selecionamos um ângulo da questão no qual apresentamos um cotejo entre pressupostos teóricos resgatados de obras de especialistas em sociologia, educação e crítica literária, a saber, Marilena Chauí (2001), Antonio Candido (1995; 2002), Bordini e Aguiar (1988) e Ligia Averbuck (1985) e apreciações feitas tanto por professores de literatura como pelo dito “senso comum” (alunos e ex-alunos de literatura sem formação específica na área) em entrevistas. A eleição deste foco para discussão se justifica pela necessidade de se estabelecer um vínculo entre a fundamentação teórica estudada nas disciplinas da Licenciatura em Português e o contexto escolar. Portanto, tendo em mente tal objetivo, elencamos os pontos de aproximação e de distanciamento entre essas posições para, de alguma forma, evidenciar dados que contribuam para as pesquisas da área.
Cânone, tradição e responsabilidade do professor: uma abordagem pela perspectiva de Hannah Arendt
Authors: Zanfra Marcello Peres
Published: January 2022

O propósito desse artigo é refletir sobre a noção de cânone literário, sobretudo a partir de considerações de Roberto Reis, Idelber Avelar e Harold Bloom pela perspectiva da pensadora alemã Hannah Arendt, considerando suas reflexões a respeito de como a tradição e o mundo público se relacionam com o sentido da educação e a utilização do cânone em sala de aula. Dentro dessa perspectiva, o cânone pode ser uma ferramenta de estudo do passado e da tradição, desde que não se torne algo que planifique a visão de mundo e anule a pluralidade de visões que são a marca essencial do mundo público arendtiano. A tradição como centro do processo educativo não significa sua reprodução acrítica, mas impedir que caia no esquecimento a fim de que os estudantes não se vejam entregues, unicamente, a suas próprias possibilidades e ferramentas. Nesse sentido, a responsabilidade do professor, por sua abordagem do texto, tem um papel central.
A presença de diferentes gêneros literários em obras de Alan Pauls
Authors: Sperb Yur Maria , Gai Eunice Piazza
Published: January 2022

Esta pesquisa aborda aspectos das obras do escritor Alan Pauls, especialmente, no que diz respeito à questão dos gêneros literários. Para isso, apresenta-se uma interpretação das seguintes obras do escritor argentino: Wasabi, O Passado, A vida descalço, História do pranto e História do cabelo.  Suas obras mantém uma escrita irreverente, por meio de uma linguagem ao mesmo tempo simples e instigante, com frases longas dando vazão a ideias que se entrelaçam e demonstram a fluidez do pensamento do escritor. Considera-se importante, neste estudo, evidenciar a mescla de gêneros como uma característica que acompanha esse autor desde o início de sua carreira e como esse hibridismo alarga as possibilidades de sentido que emergem do texto, além de buscar hipóteses das causas que levam esse autor argentino a desenvolver uma escrita tão instigante.
A masculinidade em Rosa
Authors: Pereira Marcos Aparecido , Magalhães Epaminondas de Matos , Almeida Marinei
Published: January 2022

O termo “masculinidade tóxica” está em voga, contudo, na literatura brasileira, na década de 60 já era possível encontrar personagens que questionavam esse perfil masculino pautado na força bruta, na agressividade e na não demonstração de sentimentos de carinho e afeto. Desse modo, neste trabalho, faremos um percurso analítico acerca de alguns dos personagens criados por João Guimarães Rosa, em Primeiras estórias, a fim de constatar como esse autor mineiro já traçava um delicado e, ao mesmo tempo, profundo questionamento sobre a figura do homem em sociedade e desse perfil de masculinidade. Assim, percebe-se que vários personagens já nos forneciam indicativos de uma masculinidade plural, como a defendida em nossa época.

Published: January 2022

Este artigo apresenta um recorte da pesquisa-mãe “Desafios da escola na atualidade: qual escola para o século XXI? Uma pesquisa com vários atores no estado de São Paulo” – aprovada pelo Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) em 2017 (Chamada nº 22/2016 – Pesquisa Inovação em Ciências Humanas, Sociais e Sociais Aplicadas) e desenvolvida pelo grupo de pesquisa Contexto Escolar, Processos Identitários da Formação de Professores e Alunos da Educação Básica (CEPId) – e tem como foco apontar a análise dos resultados obtidos no eixo Condições de Trabalho Docente, que teve como objetivo identificar a percepção que educadores da rede pública estadual paulista têm das condições de trabalho docente e de como tais condições interferem ou não na realização de seu trabalho. Participaram da pesquisa 5.005 educadores da rede supracitada, cujos dados foram coletados por meio de questionário on-line, viabilizado por uma plataforma digital. A fundamentação teórica que pautou a análise dos dados baseou-se em documentos oficiais da legislação brasileira e em estudos acerca do “trabalho docente” e das “condições de trabalho docente”. Ao se confrontarem os objetivos da análise nesse eixo com os dados obtidos nos questionários, buscou-se compreender os reais desafios da escola, principalmente no que concerne às condições (materiais e imateriais) necessárias para o exercício do trabalho docente. Entende-se que, no Brasil, esse tema não tem recebido atenção suficiente por parte dos governantes, sendo fundamental a construção e a efetivação de políticas públicas que visem à melhoria das condições do trabalho docente e, consequentemente, à aprendizagem dos alunos.

Results: the data are organized into two thematiccategories: "The transition of the care model: the creation of CERSAM" and "Difficulties in assistingpatients in mental distress". The Reforma Psiquiática (Psychiatric Reform) movement in BeloHorizonte allowed the first CERSAMs to be built based on the ideals of free care and centeredon the individual with psychological distress. Furthermore, the growing demand for serviceswas highlighted, followed by weaknesses related to the number of professionals in the healthnetwork services, which constitutes care gaps. Conclusion: with the creation of substitute services,improvements were arising from the Psychiatric Reform in Belo Horizonte. Despite this, it is necessaryto raise proposals for improving the services of the mental health network, aiming to reduce theburden on professionals, their improvement of primary care services. The culmination will have moreintegration between them because there will be user-centered care and, consequently, the family.
Registration of malignant diseases in estimating global cancer burden
Authors: Živković-Perišić Snežana , Miljuš Dragan , Jovanović Verica
Published: January 2022

According to the latest estimates from the World Health Organization and the International Agency for Research on Cancer, malignant diseases incidence increased to 19.3 million people worldwide, while 9.9 million deaths from all malignant tumour localizations were registered in 2020, which corresponds to an estimated incidence rate of 201.0 per 100000 population of both sexes, and mortality rate of 100.7 per 100000 population of both sexes and all ages. Over the course of their lifetimes, one in five men and one in six women will be diagnosed with cancer, and one in eight men and one in eleven women will die from some form of malignant disease. Cancer registration is organized, systematic and continuous collection, entry, storage, analysis and interpretation of data on all newly diagnosed cancer cases in a defined population, and the cancer registry is the most effective instrument for measuring cancer burden on society. The registry consists of a series of diagnosed, newly discovered cancer cases in a defined population. The basic role of the cancer registry is to enable continuous monitoring of cancer incidence over time in certain population groups, time periods and geographic locations, identification of risk factors, calculation of the burden of disease, analysis of cancer care, ecaluation of the implementation of preventative measures, planning of health care, clinical and epidemiological study and determination of direct and indirect costs of treating cancer patients (arising from temporary or permanent disability, or premature death).
Pandemic populism: COVID-19 and the rise of the Nationalist AUR party in Romania
Authors: Doiciara Claudia , Creţana Remus
Published: January 2022

Many Central and Eastern European countries elected nationalist parties after the collapse of communism: a phenomenon often attributed to a combination of socioeconomic crisis and political instability. In 2010s, after the decay of other nationalist parties, Romania was seen as an exception to this rule, but the Covid-19 pandemic times have witnessed the rapid rise of a new nationalist party: the AUR (the Alliance for the Union of Romanians). Parliamentary elections in December 2020 saw this new political force gain 9.1% of the vote. Whereas previous nationalist parties in post-Communist Romania tended to appeal to more senior/elderly voters, there is evidence that the AUR vote is strong amongst men under the age of 35 who are educated to an elementary or high school level. This paper uses national electoral data, media analysis, and in-depth interviews with young, educated people to explore the spatial distribution of AUR support, the ways in which the COVID-19 pandemic has assisted the party's rise to prominence, and attitudes amongst university students to both the style and content of their politics. The paper concludes that the AUR offer a potent mix of old nationalism, religious faith, traditional family values and new ideological elements, such as environmentalism, anti-globalization, and anti-government critique to create a self-consciously 'alternative' political rhetoric. This is presented via new channels (especially social media) in a deliberately opportunistic, controversial, and spectacular manner. However, our investigation suggests that neither the content nor the style of this politics has widespread appeal among the more educated younger participants to the interview.

Insurance represents a business activity which is becoming increasingly important for all trends in society. Namely, all commercial and other activities beneficial to society, by means of an insurance policy, ensure the safety of business, regardless of any risks that may arise. As a result, a competent and professional performance of insurance business, which among other things protects the rights and interests of insurance service users is crucial for this business activity. That is why we, in this paper, put a particular emphasis on the obligations of a competent and professional performance of the insurance business, which are stipulated by the EU Directive on insurance distribution, as well as by the National Bank of Serbia Guidelines on minimum standards of conduct and a good practice for insurance market participants.
The exogenous characteristics of traffic delinquents
Authors: Petrović Aleksandra
Published: January 2022

The exogenous characteristics of traffic participants, such as: alcoholism, fatigue and psychoactive substances, have a significant impact on a safe behaviour in traffic, especially the motor vehicle drivers. In that sense, they represent the factors that can directly influence the unsafe behaviour in traffic. The influence of the exogenous characteristics on a safe behaviour of traffic participants has been analysed on the basis of the statements in documents as well as the results of numerous empirical studies. For the purposes of this paper, there have been selected and analysed the statistical data on the influential factors of traffic accidents for the period from 2010 to 2019 in Republic of Serbia. After reviewing the statistical data, both a qualitative and quantitative content analyses were performed. In addition to the statistical method, there were also used the content analysis methods, empirical method, descriptive method, comparative methods, as well as deduction and induction methods, in order to analyse the trend and presence of these influential factors of traffic accidents in Republic of Serbia. The statistical data being processed in this paper, originated from the database of the Traffic Safety Agency of Republic of Serbia. The results of the research show the extent to which the exogenous characteristics affect a safe behaviour of traffic participants, as well as the severity of the consequences of traffic accidents. Observed individually, the listed characteristics have a different intensity of influence on a safe behaviour in traffic. In this regard, from the external characteristics of traffic delinquents, the most common is the drunk driving as an influential factor, which especially affects the severity of traffic accidents in Republic of Serbia.
The impact of macroeconomic indicators on the business performance of financial institutions in the Republic of Serbia: Panel data analysis
Authors: Račić Željko , Ercegovac Dajana , Milić Dragana
Published: January 2022

This paper aims to estimate the impact of macroeconomic indicators (gross domestic product-GDP, inflation rate and industrial production index) on liquidity, profitability and solvency of financial institutions in the Republic of Serbia. The research is based on applying a dynamic GMM panel model, while the results of the application of static panel models were analyzed as the control results. The research results support the assumption that the growth of GDP and inflation rates affects the increase of financial institutions' profitability. Also, the estimation results implicate that the growth of GDP and the inflation rate is linked with the reduction of financial institutions' liquidity, while the growth of industrial production rate affects its increase. Finally, the results of the study indicate that GDP growth has an influence on the rise of financial sector solvency. This comparative analysis using panel data models is relevant to a broad range of researchers and policymakers interested in macroeconomic relations and the financial sector.

Published: January 2022

Video endoscopy is an important modality for the diagnosis and treatment of various gastrointestinal diseases. Most endoscopic procedures are performed as outpatient basis, sometimes requiring sedation and deeper levels of anesthesia. Moreover, advances in endoscopic techniques have allowed invasion into the third space and the performance of technically difficult procedures that require the utmost precision. Hence, formulating strategies for the discharge of patients requiring endoscopy is clinically and legally challenging. In this review, we have discussed the various criteria and scores for the discharge of patients who have undergone endoscopic procedures with and without anesthesia.

Authors: Caponnetto Mario
Published: January 2022

A new method for the optimisation and design of Contra-Rotating Propellers (CRP) is presented in this paper. It is based on a Genetic Algorithm (GA) applied to a Vortex Lattice Method, used to compute the optimum spanwise distribution of circulation. chord length and thickness. Computation of the pitch and camber distribution is then performed with a design Panel Method (DPM). Both codes are used in a loop of iterations in order to take into account of the reciprocal interaction of the two propellers and their wakes. Blade optimisation is performed within several constraints such as cavitation avoidance and structural strength requirements.
Non-axisymmetric Effective Wake Prediction by Using an Unsteady Three-Dimensional Euler Solver
Authors: Choi Jin-Keun , Kinnas Spyros A.
Published: January 2022

A fully three-dimensional unsteady Euler solver, based on a finite volume approach and the pressure-correction method, is developed and applied to the prediction of the effective wake for propellers subject to non-axisymmetric inflows. The method is coupled with an existing vortex lattice method for the analysis of unsteady cavitating propeller flows. The propeller is modeled as the unsteady force at the location of the blade and appears as the body force term in the Euler equations. The unsteady Euler solver is first validated against the solution obtained by a previously developed steady Euler solver for a non-axisymmetric inflow, and then against the solution by the potential flow solver in the uniform inflow case. The unsteady effective wake is predicted for a non-axisymmetric nominal wake, and it is found that the unsteadiness in the effective wake is small in this case. Lastly, the predicted total velocity field is compared with the experimental data obtained from the MIT water tunnel.
A Genetic Algorithm (GA) Based Optimization Technique for the Design of Marine Propeller
Authors: Karim Mashud , Ikehata Mitsuhisa
Published: January 2022

A genetic algorithm (GA) based optimization technique for the design of systematic series propellers, e.g., B-series, Gawn, Newton-Rader series etc. is studied in this research and its applicability has been verified. Using polynomial expressions for thrust and torque coefficients of these propellers as functions of blade area ratio, pitch ratio, advance coefficient and number of blades, GA searches for an improved propeller of maximum efficiency under some design requirements and imposed constraints. In this study, GA is found as a reliable tool for optimization of marine propeller.
PTFE Compound Bearing for Water Lubricated Shaft Systems
Authors: Yamajo Seiji , Kikkawa Fumitaka
Published: January 2022

The paper outlines the development and applications of compound bearings made of PTFE (Poly Tetra Fluoro Ethylene) and synthetic rubber, which enable the shaft to start up without initial lubricating water. The unique characteristic is the three-layer structure using elastic, synthetic rubber which is sandwiched between the PTFE compound and the outer metal shell. This special structure is designed to solve bearing issues that are incompatible with each other. That the bearing has sufficient hardness to be excellent against wear and yet is flexible to compensate for shaft misalignment and vibration. Friction characteristics and performance data are introduced comparing PTFE and conventional rubber bearings. Long-time running tests are carried out in very demanding conditions and the test data are shown. Over 15 years of actual operational service data on naval vessels and high speed, long-distance cruising ferries are introduced.

Published: January 2022

The majority of thrusters used for the position control of tethered underwater vehicles have asymmetric propulsion characteristics. This paper presents the results of a hydrodynamic design optimisation of a bi-directional integrated thruster. A surface panel method using the perturbation potential method of Morino was used for the optimisation. The model was validated with experimental data giving good agreement. Two versions of the prototype thruster have now been built and tested In this paper details are given of the design optimisation process for the next generation of thruster for use on a work class Remotely Operated Vehicle. A 2-D potential code coupled with integral boundary layer equations has been used to derive an optimum blade section shape for equal performance in both directions. Using the derived sections the complete thruster was optimised for a given operating condition.

The increased severity of bilge discharge regulations imposed 011 coastal shipping has required a new type of stern tube sealing device which has a longer life and excellent sealing performance. A face-type seal with a uniquely shaped sealing ring made of rubber was developed and has been applied to various vessels instead of the conventional gland packing system. It has been very successful in service in blue water. However, heavy wear and leakage problems 011 sliding surfaces were observed 011 some boats operated in brown water. Many types of tests were carried out in order to develop a special stern tube seal for brown water. Excellent results, as shown in this paper, were obtained.

O presente artigo se origina de uma pesquisa desenvolvida no Curso de Graduação em Artes Cênicas da Universidade Federal de Ouro Preto, Minas Gerais, no período de 2011 a 2013. Por meio da disciplina “Oficina de Criação Cênica A”, orientada através dos estudos com o Teatro de Animação, que surgiu o espetáculo teatral de rua com bonecos gigantes, intitulado “O Gigante e o Dragão”. Aqui, o principal objetivo é apresentar a pesquisa e os processos que permearam a concepção, a confecção e o experimento cênico deste espetáculo e, sobretudo, apontar o quanto é potente a reciclagem, a reutilização e a ressignificação de diversos materiais, no intuito de se criar linguagens expressivas.
Rumo a uma mudança sustentável. Habilidades manuais em Teatros de Bonecos poloneses: uma perspectiva ecosófica
Authors: Smolarska Zofia , Vieira Letícia
Published: January 2022

O principal objetivo do artigo é apresentar e explicar a complexidade do conflito profundo, mas oculto, entre o “topo” e a “base” que está ocorrendo atualmente em muitas instituições teatrais na Polônia, incluindo Teatros de Bonecos. Desde 1989, os teatros de repertórios poloneses têm continuamente se transformado do antigo e altamente hierárquico modo de produção Fordista, para o novo e flexível modo pós-Fordista, que é característico do capitalismo cognitivo e do teatro alternativo neovanguardista. Essas mudanças organizacionais e algumas novas tendências estéticas estão levando à extinção da construção teatral artesanal, na medida em que o trabalho dos artesãos é cada vez mais terceirizado ou substituído por objetos prontos. Este artigo apresenta os resultados de uma pesquisa de campo qualitativa realizada em seis instituições de Teatro de Bonecos poloneses, cada uma com um alcance diferente, incluindo entrevistas com artesãos teatrais, a fim de examinar as decisões econômicas, tecnológicas e estéticas que causam disfunções e exacerbam a extinção das profissões teatrais de bastidores.

Hematologic malignancies often create difficult venous complications. Specifically, with lymphoma, the risk of venous thromboembolism (VTE) is high, often requiring highly specialized accuracy in balancing this coagulopathy. This case study demonstrates a situation where the advanced practitioner participated in the differential diagnosis of VTEs, management, and workup of subsequent central venous complications in a patient with non-Hodgkin lymphoma and superior vena cava syndrome.

Background: To describe short-term outcomes and independent predictors of 28-dayx mortality in adult patients with hematologic malignancies and septic shock defined by the new Third International Consensus Definitions (Sepsis-3) criteria. Methods: We performed a retrospective cohort study of patients admitted to the medical ICU with septic shock from April 2016 to March 2019. Demographic and clinical features and short-term outcomes were collected. We used descriptive statistics to summarize patient characteristics, logistic regression to identify predictors of 28-day mortality, and Kaplan-Meier plots to assess survival. Results: Among the 459 hematologic patients with septic shock admitted to the ICU, 109 (23.7%) had received hematopoietic stem cell transplant. The median age was 63 years (range, 18–89 years), and 179 (39%) were women. Nonsurvivors had a higher Charlson comorbidity index (P=.007), longer length of stay before ICU admission (P=.01), and greater illness severity at diagnosis and throughout the hospital course (P<.001). The mortality rate at 28 days was 67.8% and increased with increasing sequential organ failure assessment score on admission (odds ratio [OR], 1.11; 95% CI, 1.03–1.20), respiratory failure (OR, 3.12; 95% CI, 1.49–6.51), and maximum lactate level (OR, 1.16; 95% CI, 1.10–1.22). Aminoglycosides administration (OR, 0.42; 95% CI, 0.26–0.69), serum albumin (OR, 0.51; 95% CI, 0.31–0.86), and granulocyte colony-stimulating factor (G-CSF) (OR, 0.40; 95% CI, 0.24–0.65) were associated with lower 28-day mortality. Life support limitations were present in 81.6% of patients at death. At 90 days, 19.4% of the patients were alive. Conclusions: Despite efforts to enhance survival, septic shock in patients with hematologic malignancies is still associated with high mortality rates and poor 90-day survival. These results demonstrate the need for an urgent call to action with higher awareness, including the further evaluation of interventions such as earlier ICU admission, aminoglycosides administration, and G-CSF treatment.
Uncertainty, responsibility, and reassurance in paediatric palliative care: A conversation analytic study of telephone conversations between parents and clinicians
Authors: Sansone Holly Marie , Ekberg Stuart , Danby Susan
Published: January 2022

Background: Families play a vital role in the day-to-day medical care of children with life-limiting conditions. Navigating their child’s symptoms, treatments, and the possibility of sudden deteriorations, presents myriad challenges and can be distressing for the family. Paediatric palliative care can provide crucial support for families who are typically responsible for many aspects of their child’s care. Aim: To understand how paediatric palliative care clinicians use reassurance to support families through the uncertainties associated with caring for their children. Methods: One hundred routine telephone conversations between parents and clinicians of a paediatric palliative care service were recorded and analysed using Conversation Analytic methods. Findings: When parents report uncertainty about a specific care task, imply a causal link between this care task and an adverse outcome for their child, and a moral responsibility for the outcome, clinicians respond with reassurance. Clinicians produce reassurance through refuting parents’ accounts and providing an explanation to reframe the potential adverse outcome as independent of parent actions. Parents often agree with the clinicians’ reframings and demonstrate being reassured. Discussion: Specialist paediatric palliative care clinicians routinely foreground support for family members through reassurance. Conclusions: This study demonstrates how family-centred care can be accomplished in clinical practice.

The aim of this study was to establish the eff ect of corporate social responsibility (donations, sponsorship and community involvement) on brand awareness within the insurance sector in Zimbabwe. Data was gathered from 350 insurance customers using a structured questionnaire with Likert-type questions. The fi ndings show that corporate social responsibility positively infl uences brand awareness. The study contributes to studies that proved a signifi cant relationship between corporate social responsibility and brand awareness in sectors other than the insurance sector. Thus, insurance fi rms are advised to seriously plough back proceeds to their communities.
