THE CHALLENGES OF MAJOR TANK COATING REFURBISHMENT PROJECTS FOR ON-STATION FLOATING ASSETS
Authors: Westwell A
Published: December 2021

The objective of this paper is to acknowledge that major tank coating refurbishment projects to FPSO’s and FSU’s are likely to be required during the life of these assets. It highlights the key challenges of achieving these major coating projects in an offshore environment, whilst the assets remain operational and in-production. As these floating assets age the original coatings applied to protect the internal (and external) hull, deteriorate. In an industry with a reluctance for extensive dry-dockings, there is an expectation that any coating refurbishment campaigns can be achieved safely and efficiently whilst the assets remain on-station and in-production, in preference to costly steel renewal’s which may be required at a future date if coatings are not maintained in good condition. With often complex, congested and hazardous topsides processing equipment and pipework directly above the hull tanks, there’s a need for systems, procedures, and specialist equipment to ensure the safety of the personnel entering confined spaces for extended periods. There’s also a need to plan and engineer the works appropriately, using best practice and emergent technologies to improve safety, reduce bedding impacts and to ensure the success of the coating campaign. This paper explores the challenges of major coating projects by discussing the importance of planning and preparation, the need to create a safe working environment within the confined space worksites, the role surface preparation plays in the success of coating projects, and finally the application of coatings and the challenges this operation can present. The key considerations are summarised in 10 specific conclusions as guidance to promote successful project outcomes.
NON-UNIFORM RATIONAL B-SPLINE BASED ISO-GEOMETRIC ANALYSIS FOR A CLASS OF HYDRODYNAMIC PROBLEMS
Authors: Goel M , Sharma R , Bhattacharyya S K , Kim Tae-wan
Published: December 2021

Herein, we present the design and development of a ‘Non-uniform Rational B-spline (NURBS)’ based iso-geometric approach for the analysis of a number of ‘Boundary Value Problems (BVPs)’ relevant in hydrodynamics. We propose a ‘Potential Function’ based ‘Boundary Element Method (BEM)’ and show that it holds the advantage of being computationally efficient over the other known numerical methods for a wide range of external flow problems. The use of NURBS is consistent, as inspired by the ‘iso-geometric analysis’, from geometric formulation for the body surface to the potential function representation to interpolation. The control parameters of NURBS are utilised and they have been explored to arrive at some preferable values and parameters for parameterization and the knot vector selection. Also, the present paper investigates the variational strength panel method, and its computational performance is analyzed in comparison with the constant strength panel method. The two variations have been considered, e.g. linear and quadratic. Finally, to illustrate the effectiveness and efficiency of the proposed NURBS based iso-geometric approach for the analysis of boundary value problems, five different problems (i.e. flow over a sphere, effect of the knot vector selection on analysis, flow over a rectangular wing section of NACA 0012 aerofoil section, performance of DTMB 4119 propeller (un-skewed), performance of DTNSDRC 4382 propeller (skewed)) are considered. The results show that in the absence of predominant viscous effects, a ‘Potential Function’ based BEM with NURBS representation performs well with very good computational efficiency and with less complexity as compared to the results available from the existing approaches and commercial software programs, i.e. low maximum errors close to 110−3 , faster convergence with even up to 75 % reduction in the number of panels and improvements in the computational efficiency up to 32.5 % even with low number of panels.
INTRODUCING OPERATIONAL INFORMATION INTO EARLY STAGE SHIP DESIGN USING QUEUEING NETWORKS
Authors: Droste K , Hopman J J , Kana A A , Van Oers B J
Published: December 2021

During the early stages of ship design a set of requirements needs to be identified, accounting for financial and technical feasibility, and operational effectiveness. This process of requirements elucidation creates a need for information regarding various design alternatives and their effect on the feasibility and effectiveness of the design requirements. When one considers internal layout and process driven ships, ships where the arrangement of spaces has a strong influence on the effectiveness of the ship's operational processes, a gap in available methods has been identified. This paper proposes a method based on queueing networks that allows a naval architect to study the effects of different arrangements on the execution of various sets of operational processes. Using this model a better understanding of the interaction between the ship's arrangement and its operational processes can be obtained. This understanding can improve the requirements elucidation process and can lead to the development of better design requirements.
A FUTURE FORETASTE: SHIPBUILDING INDUSTRIAL TENDENCIES
Authors: Fernandez R Pérez , Péter Cosma E
Published: December 2021

We are living a continuous and fast technology evolution, maybe this evolution goes faster than our capacity to assimilate what we can do with it, but the potential is clear and the future will be for those who identifies the right technology with the right application. The way we work with Computer Aided Design (CAD) tools is also changing thanks to the ubiquitous access to information and the different hardware available to exploit that information: Augmented Reality, Virtual Reality or Mixed Reality. Not only the way we work, but also the way we interact with CAD tools is changing, with technologies like natural language processes that allows direct conversation with the applications. The concepts that are absolutely clear from now to the future in shipbuilding are the use of Data Centric models and the concept of Digital Twin. Both provide a real and effective synchronization between what we design and what we construct, by covering the complete life cycle of the product, thanks to technologies like the Internet of Things (IoT) and Radio Frequency IDentification (RFID). Nowadays it is unimaginable to work without using CAD in shipbuilding: ease of design with design rules embedded, speed of design, and the use and reuse of information. It is expected that in the future CAD tools will advance further and allow greater information management through further improvements. The paper presents several scenarios with improvements likely to occur the next few years. Some of these improvements may seem unrealistic in the short term, but reality often exceeds expectations in any field, and probably more so with technology.
Os anos iniciais do futebol feminino em Santa Catarina: silenciamentos e resistências
Authors: Matos Felipe
Published: December 2021

O artigo produz uma síntese histórica sobre os espaços ocupados e os papéis desempenhados pelas mulheres no campo esportivo em Santa Catarina ao longo do século XX e o desenvolvimento do futebol de mulheres, cuja prática foi por quase quatro décadas (1941-1979) oficialmente proibida por decreto-lei, sendo que a sua regulamentação ocorreu apenas no ano de 1983. Tal interdição, baseada em premissas biológicas e legitimada pela estrutura patriarcal conservadora brasileira, marginalizou a modalidade e retardou o seu desenvolvimento, ao contrário da categoria masculina, que se tornou o esporte mais popular do país. Em sintonia com o que ocorria nos grandes centros urbanos, em Santa Catarina o futebol foi visto como um esporte masculino carregado por marcas civilizatórias, praticado por uma elite que reservou às mulheres o papel de torcedora. A sua prática pelas mulheres iniciou como atração circense, tentou desenvolver-se como atividade educativa, foi coibido, estabeleceu estratégias de resistência para continuar sendo praticado até poder estruturar-se em suas diversas manifestações profissionais, de lazer, de educação e sociabilidade.
Infodemia e construção sígnica – movimentos responsivos sob a retórica da pós-verdade
Authors: Lopes Maria Angela Paulino Teixeira , Gomes Fernanda Santana
Published: December 2021

Sob a retórica da pós-verdade, a infodemia e a desinformação atingiram grandes proporções, com impactos negativos na esfera social (KALIL; SANTINI, 2020; ORGANIZAÇÃO MUNDIAL DA SAÚDE, 2020), gerando um cenário de instabilidade, marcado por imprecisão, medo, marginalização e preconceitos. Visando contribuir para as práticas de letramento em leitura nas instâncias formativas, especialmente, as educacionais, neste artigo iremos explorar o fenômeno da desinformação (ALLCOTT; GENTZKOW, 2017; WARDLE; DERAKHSHAN, 2017), tomando como objeto analítico o discurso de abertura do presidente Jair Messias Bolsonaro, na 75ª Assembleia Geral da Organização das Nações Unidas, proferido em setembro de 2020. Grande parte desse discurso consiste em informações imprecisas e desprovidas de argumentos fundamentados, sobretudo, no que se refere ao contexto da pandemia pela Covid-19 no Brasil e à destruição de biomas brasileiros de extrema relevância para o ecossistema mundial. Considerando o evento enunciativo em análise, buscamos compreender e problematizar como as posições avaliativas do enunciador, atravessadas pelos valores ideológicos do(s) lugar(es) que ocupa no contexto sócio-histórico, podem ser capazes de afetar a interlocução com a sociedade. Com a pretensão de atingir o objetivo proposto, recorremos ao aporte teórico desenvolvido pelo círculo bakhtiniano, especialmente, os conceitos de responsividade, posicionamento axiológico e refração (BAKHTIN, 2011; 2017; VOLÓCHINOV, 2013; 2017), e a considerações acerca do discurso polêmico construído sob o viés do dissenso (AMOSSY, 2015; 2017).
Competências em práticas letradas de estudantes de Ensino Médio no contexto da desordem informacional
Authors: Ciencia Ana Cláudia Bertini
Published: December 2021

Este artigo objetiva discutir competências de alunos de Ensino Médio em práticas sociais de leitura e escrita mediadas por mídias digitais, no contexto da desordem informacional e no tocante à identificação de informação falsa. O estudo ancora-se nos pressupostos dos Novos Estudos de Letramentos (New Literacy Studies), especificamente no que se refere à formação do leitor, a partir dos quais se descrevem e discutem orientações da Base Nacional Comum Curricular (BNCC). O conjunto do material é formado por 105 produções textuais coletadas em uma escola pública de São José do Rio Preto, interior de São Paulo, no primeiro semestre de 2019. Embora tanto a coleta do material quanto a BNCC sejam anteriores à pandemia da covid-19, faz-se pertinente problematizar também essa crise sanitária, a qual potencializou um contexto de “infodemia” e evidenciou desigualdades no acesso à educação. A análise dos dados demonstra que os estudantes de Ensino Médio são competentes em reconhecer informação falsa com base em critérios relacionados ao uso de norma culta. No entanto, parecem desconhecer questões não relacionadas diretamente a aspectos linguísticos e ignorar o atravessamento de vozes e crenças particulares no processo da desordem informacional. O trabalho aponta para o confronto entre as expectativas e orientações da BNCC e os letramentos que precisam ser discutidos e trabalhados pela instituição escolar, pensando, principalmente (mas não apenas) numa vida pós-pandemia.
Letramento crítico no Ensino Médio: uma proposta didática sobre pós-fatos contra o Nordeste/nordestino(a) em aulas de Língua Portuguesa
Authors: Santana Mariana Galdino
Published: December 2021

Compreendemos que cabe à escola, e especialmente à docência de Língua Portuguesa, preparar alunos e alunas para uma leitura cuidadosa e responsiva da produção informacional e midiática, possibilitando um olhar crítico sobre a “objetividade” dos fatos, colaborando, desse modo, com a (re)construção e problematização de um sentimento de pertencimento a uma territorialidade, quando os textos para o ensino e a aprendizagem da linguagem têm como objeto de discurso uma região e seu povo. Assim, se sabemos que a disseminação de notícias falsas e de pós-verdades pode ocasionar vários danos à sociedade em geral e às pessoas especificamente, proponho-me, nesse artigo, à reflexão, em aulas de Língua Portuguesa, acerca da formação do letramento crítico de estudantes do Ensino Médio, a partir do trabalho com textos, informação midiática e a cultura do “pós-fato” em que a temática seja o Nordeste e o(a)s nordestino(a)s. Para tanto, sugere-se um Plano de Ensino mensal com fito de construir uma leitura crítica e fomentar a formação de opinião a partir da recepção de “pós-fatos” que tomam como referente o Nordeste e o(a)s nordestino(a)s.  O plano em questão prevê discutir com os alunos questões éticas, sociais e de formação do sujeito contemporâneo, interessada nos processos de ensino e de aprendizagem, em aulas de Língua Portuguesa, para a formação de leitor(a) crítico(a) frente à (própria) territorialidade.

O papel da memória discursiva em manchetes que desmentem notícias sobre Covid-19
Authors: Alexandre Gabriel Guimarães
Published: December 2021

A pandemia de Covid-19 trouxe-nos um contexto de exceção. Restrições impostas à sociedade foram aplicadas por governos de diferentes partes do mundo, gerando dificuldades, por exemplo, de escolha entre ter privacidade de dados ou saúde prometida por vigilância biométrica (HARARI, 2020). Como “resposta” à disseminação de fake news – não só sobre a doença, mas também sobre outros temas – as agências de fact-checking (PANGRAZIO, 2018; SPINELLI, SANTOS, 2018) surgem com o objetivo de verificá-las, classificando-as em “verdadeiras” ou “falsas”, segundo gradação. Quando publicam a checagem realizada, as agências utilizam manchetes que desmentem as notícias. Entre os padrões linguísticos observados, a negação é bastante frequente nas manchetes verificadas em mídias sociais. Por ser um índice de implícito, está presente no enunciado para produzir sentido: a memória discursiva é, pois, um modo de compreender o estatuto dos implícitos (ACHARD, 1999; PÊCHEUX, 1999). Logo, partimos da hipótese de que a prática de estruturar a negação, nas manchetes analisadas, pode fazer emergir questões interlocutivas via evocação de certa memória discursiva. Com base em pressupostos teórico-metodológicos dos estudos de letramentos (New Literacy Studies) e da Análise do discurso francesa, este trabalho objetivou analisar o papel da memória discursiva em 68 manchetes, publicadas em março de 2020 por duas agências (“Chequeado” e “Agência Lupa), as quais desmentem notícias sobre Covid-19 em mídias sociais. Os resultados obtidos permitiram identificar três estruturas de negação frequentes nas manchetes e parecem confirmar a hipótese de partida, contribuindo com os estudos de letramentos, quanto à formação do leitor em tempos de pandemia.

Preparation of Tissues and Heterogeneous Cellular Samples for Single-Cell Analysis
Authors: Celeste Welch E. , Tripathi Anubhav
Published: December 2021

While sample preparation techniques for the chemical and biochemical analysis of tissues are fairly well advanced, the preparation of complex, heterogenous samples for single-cell analysis can be difficult and challenging. Nevertheless, there is growing interest in preparing complex cellular samples, particularly tissues, for analysis via single-cell resolution techniques such as single-cell sequencing or flow cytometry. Recent microfluidic tissue dissociation approaches have helped to expedite the preparation of single cells from tissues through the use of optimized, controlled mechanical forces. Cell sorting and selective cellular recovery from heterogenous samples have also gained traction in biosensors, microfluidic systems, and other diagnostic devices. Together, these recent developments in tissue disaggregation and targeted cellular retrieval have contributed to the development of increasingly streamlined sample preparation workflows for single-cell analysis technologies, which minimize equipment requirements, enable lower processing times and costs, and pave the way for high-throughput, automated technologies. In this chapter, we survey recent developments and emerging trends in this field.
Study of Electromagnetic Radiation Sources Using Time Reversal: Application to a Power Electronic Converter
Authors: Hedia Sassia , Zitouna Bessem , Ben Hadj Slama Jaleleddine , Pichon Lionel
Published: December 2021

Recently, modern power electronic systems have been introduced in different applications, such as in avionics and wireless communication. The increasing technological complexity of these systems is posing serious challenges regarding electromagnetic compatibility (EMC) issues. Indeed, the radiation emitted from electronic circuits can induce harmful effects on nearby devices. Thus, several research works have been conducted using the nearfield technique to deal with electromagnetic interferences (EMI) that might occur, especially due to rapidly changing currents and voltages. In the present work, a detailed study about the characterization of the electromagnetic nearfield-radiated emissions is established using a time-domain analysis to provide an equivalent model constituted of a set of electromagnetic dipole parameters. Source reconstruction has been obtained using electromagnetic time reversal (EMTR), which has proven successful and efficient in identifying transient disturbance sources in power electronics. Experimental measurements of the magnetic nearfield have been carried out under an AC/DC flyback converter. The accuracy of the proposed method has been confirmed by visualizing measured magnetic field components, which are in good agreement with the calculated maps. The results of a reasonable computing time have shown that, particularly in transient signals with a wide frequency band, the suggested inverse method is an adequate alternative to overcome frequency domain limitations.
Strategies for Goat Feeding and Management during Drought
Authors: Faji Dida Mulisa
Published: December 2021

Nowadays, climate change is becoming a serious problem threatening livestock production by affecting their environment, health, and feed sources. Many parts of the tropical countries, particularly the pastoralist area, experience extended periods of drought, leading to shortages of feed and water. During these periods, goats are incapable of meeting their nutrient requirement for maintenance and will begin to lose weight as body reserves are depleted, causing economic loss to the goats. In the extremely long dry season, animals die, with the youngest, weakest, and oldest dying first. As a result, drought management entails balancing pasture and water supply against forage and water demand. In most cases, no single strategy will suffice to address this issue. Each situation would need a different set of strategies Therefore, this chapter will come with some common options/ strategies that can be avail feed shortage during drought. Those strategies are purchase of feed from surplus location, adjustment of animal management, policy intervention, destocking, adjusting grazing strategies during drought, supplementation, maintenance feeding, reallocation of a given amount of feed in the herd, early weaning and creep feeding, lowering stocking rate, water sources and supplies, development and effective utilization of feed resources, and creation of feed banks.
Resonance Raman Spectroscopy Investigation of the Interaction of Molecules Adsorbed on Solid Acid Surfaces
Authors: Kiyomi Noda Lucia
Published: December 2021

Many solid acids with very strong acid sites, as some zeolites, transition metal exchanged montmorillonites, sulfated metallic oxides, are known to have the oxidizing ability, which can be related to the catalytic activity of these materials. The interaction of these solid acids with aromatic molecules can give rise to several oxidation products. Intermediate species of aromatic molecules formed by interaction with strong solid acids had been reported, as radical cations, proving the oxidizing ability of the solids. Besides radical cations, charge transfer complexes between the solid acids and aromatic molecules can be formed. These radical cations and charge transfer complexes usually show absorption bands in the visible region, opening the possibility of studying these species by Resonance Raman Spectroscopy (RRS). Benzene and substituted benzenes, phenothiazine, t-stilbene, adsorbed on solid acids, are examples of molecules that had been investigated by RRS. Exciting the spectrum with suitable radiation makes it possible to observe the RRS of the species of interest even when its concentration is low, because of the preferential enhancement of the vibrational modes of the chromophore. A review of RRS studies of molecules adsorbed on solid acids is presented. RRS proved valuable in characterizing intermediate species as radical cations or charge transfer complexes formed on the solid acids.
Folliculogenesis, Fertility and Biotechnology in Dairy Cattle
Authors: M. Seneda Marcelo , B. Delchiaro Sofia , F. Zangirolamo Amanda , A. Alfieri Amauri , Morotti Fabio
Published: December 2021

The ovarian follicle population is formed by thousands of follicles, preantral and antral, where oocytes are included. During fetal life, the first follicles produced are preantral, and, as they undergo the development process, they reach the final stage of antral follicles, where a cavity/or antrum is developed. All this growth phase is called folliculogenesis, and this chapter will abord the most important aspects of this process. Moreover, not all follicles reach the preovulatory phase and can be fertilized, so we will discuss how reproductive biotechniques can positively influence the fertility of bovine females. We will also discuss the possibility of antral follicle count to influence reproductive performance and the correlation to biotechniques. Finally, we present alternatives on how to improve fertility and productive efficiency in dairy herds.

Authors: Harsono Arief , Harnowo Didik , Ginting Erliana , Adi Anggraeni Elisabeth Dian
Published: December 2021

Soybean is the third important food crop in Indonesia after rice and maize, particularly as a good source of protein. The demand for soybean consumption tends to increase annually. In 2020, the figure was about 3.28 million tons, while the domestic production was 0.63 million tons, thus around 81% of the soybean needed was imported. Efforts to increase the domestic soybean production have been conducted since the last decade, which is concerned with increasing the current productivity (1.5 t/ha) through introducing the high-yielding improved varieties and extending the harvested area, particularly to outside of Java. The potential planting area is focused on the irrigated lowland after rice (optimal land) and suboptimal lands (dry, acid, tidal, and shaded lands). The series of the study showed that the yield potential of soybean grown in such lands varied from 1.8 t/ha to 3.0 t/ha. A number of soybeans improved varieties adapted to different land types or agro-ecological conditions also have been released and supported with advanced cultivation technology. The results, challenges, and opportunities to achieve soybean self-sufficiency are discussed in this paper.
Adaptive Optics Imaging Technique in Diabetic Retinopathy
Authors: Baltă Florian , Elena Cristescu Irina , Teodora Tofolean Ioana
Published: December 2021

Adaptive optics ophthalmoscopy opened a new era in the medical retina field. The possibility of obtaining high-resolution retinal images of photoreceptors and retinal vessels addresses new perspectives in retinal physiology and pathophysiology. The overwhelming incidence of diabetes in the global population justifies the need to develop and refine methods of diagnosing early retinal changes, in order to preserve vision and avoid complications. The current grading of diabetic retinopathy is based on clinical changes only. Nevertheless, imaging tools such as optical coherence tomography and optical coherence tomography angiography are also used for screening of this pathology. The corroboration of the information provided by these imaging methods may lay the foundations for a new approach to the definition and diagnosis of diabetic retinopathy.
SFE2D: A Hybrid Tool for Spatial and Spectral Feature Extraction
Authors: Abbassi Bahman , Zhen Cheng Li
Published: December 2021

A crucial task for integrated geoscientific image (geo-image) interpretation is the relevant geological representation of multiple geo-images, which demands high-dimensional techniques for extracting latent geological features from high-dimensional geo-images. A standalone mathematical tool called SFE2D (spatiospectral feature extraction in two-dimension) is developed based on independent component analysis (ICA), continuous wavelet transform (CWT), k-means clustering segmentation, and RGB color processing that iteratively separates, extracts, clusters, and visualizes the highly correlated and overlapped geological features from multiple sources of geo-images. The SFE2D offers spatial feature extraction and wavelet-based spectral feature extraction for further extraction of frequency-dependent features. We show that the SFE2D is a robust tool for automated pattern recognition, fast pseudo-geological mapping, and detection of regions of interest with a wide range of applications in different scales, from regional geophysical surveys to the interpretation of microscopic images.

Published: December 2021

This chapter validates the capability of CFD modelling technique to accurately describe processes in the thermal storage system with the PCM. For validation purposes, CFD modelling using FLUENT ANSYS was conducted and the predicted results were compared with the experimental and numerical data from the literature. The comparison between experimental and numerical results was carried out in terms of the temperature distributions and average volume of the PCM liquid fraction. Additionally, the detailed parametric study of the storage system with the PCM was performed and results obtained were discussed with dimensional correlations for the Nusselt number being proposed to be used in the designing process. Finally, a correlation was developed to estimate the total melting time at the thermal storage system.

Published: December 2021

Plants, especially herbs and spices, have always been the major sources of numerous natural compounds with antioxidant activity and other beneficial properties and, specifically, Rosemary (Rosmarinus officinalis L.) has been widely accepted as one of the spices with highest antioxidant activities which appear to be related to their richness of phenolic compounds. This study was undertaken with the aim to estimate the total phenolic content, identify and quantify the polyphenolic compounds of the methanolic extracts from post-distilled rosemary, collected from two different bioclimatic areas from Tunisia. Total phenolic content (TPC) was determined by Folin–Ciocalteu method. Identification and quantification of polyphenolic compounds was performed using high-performance liquid chromatography (HPLC) analysis. TPC ranged from 85.8 to 137.3 mg GAE/g DE in rosemary extracts. HPLC analysis showed the presence of carnosic acid and carnosol, wich were found to be the most abundant compounds in all analyzed extracts (46.3 to 76.4 and 22.4 to 43.5 mg/g of plant dry weight respectively), rosmarinic acid and caffeic acid as phenolic acids, besides some flavonoids such as apigenin, luteolin, genkwanin and hesperidin. This study revealed that rosemary post-distilled residues were shown to be promising with regard to their incorporation into various foods, cosmetics and fragrances.Therefore, supplementing a balanced diet with herbs may have beneficial health effects.
Co-Design Block PA (Power Amplifier)-Antenna for 5G Application at 28 GHz Frequency Band
Authors: Joel Nounga Njanda Ange , Samuel Mandeng Paul
Published: December 2021

This subject addresses the issue related to Transmitters for the new communication standard, namely 5G. Indeed to respond to the problems of radio coverage, the speed of services as well as the rise in user demand, transmitters must have ideal characteristics to be able to meet these requirements. This chapter proposes in order to answer such a problem a block made up of a linear array of antennas has 4 elements and a transistor amplifier operating at the 28 GHz frequency band. The Design of the Block is done first by the design of the antenna then the design of the amplifier and finally the junction of the two devices with a matching network to therefore form the block of transmitters Speaking of the design of the antenna, the prepared antenna is a patch antenna with a patch shape excluding the classic shapes which is printed on a Rogers-Duriod 5880 substrate so the thickness is 0.127 mm, the linear antenna array proposed has a gain greater than 15 dB and a Good Bandwidth, the transistor amplifier is in turn printed on the same substrate has the same thickness to minimize the losses during the junction of this one with the antenna, this amplifier offers a higher gain than device 15 dB and therefore the Bandwidth is greater than 2 GHz, each transmitter has an input and output reflection coefficient of less than −10 db. The simulation of each transmitter is made with the CST-microwave software for the Antenna and the ADS (Advanced Design System) software for the amplifier and the Block PA-Antenna. It is important to note that the Block output impedance is 50 ohms making our device more practical and easily commercial.

Resilience and sociodemographic factors involved in the presence of depressive, anxiety and of stress symptoms in the Chilean adult population during the COVID-19 pandemic
Abstract: The COVID-19 pandemic has caused a great impact on people’s mental health. The objective of this study was to examine the role of resilience and sociodemographic factors involved in the presence of depressive, anxiety and stress symptoms in the Chilean adult population during the COVID-19 pandemic. A sample of 501 participants answered the Depression, Anxiety and Stress Scales (DASS-21) and the 10-item Connor-Davidson Resilience Scale (CD-RISC-10). The results indicate that there are high prevalence rates of mental health symptoms during the current health crisis. We found that resilience is inversely associated with the three types of symptoms, also turning out to be a predictor variable for them. It may be concluded that there are groups with a higher risk for experiencing higher levels of depressive, anxiety and stress symptomatology, which indicates the importance of developing strategies that promote mental health.
Keywords: COVID-19; resilience; depression; anxiety; stress.

Eating disorders, life stressful events and body image: A systematic review
Abstract: Our objective was to clarify the relationship between adverse life events and the altered body image in eatingdisorders. We reviewed English and Spanish papers indexed in MEDLINE, PsycINFO and ScienceDirect from the last 10years. We included 16 studies of which 37.5% focus on eating disorders. Sexual abuse, physical abuse, domestic violence,bullying and having experienced multiples adverse life events have been associated with overweight patients and high body dissatisfaction. Emotional abuse has been associated with underweight and body shape concerns. Posttraumatic symptoms and emotion dysregulation have been identified as mediating factors. Eating disorder psychopathology could be the response to a bad regulation of negative emotion coming from different adverse life events and this mechanism could underlie patiens’ body dissatisfaction.
Keywords: eating disorders; adverse life events; bulimia nervosa; anorexia nervosa; binge-eating disorder; body image; body dissatisfaction; traumatic events.
Resumen: El objetivo de este trabajo es esclarecer la relación entre experiencias adversas vitales y la alteración de la imagen corporal en los trastornos alimentarios. Se han revisado trabajos en inglés y castellano indexados en MEDLINE, PsychoINFO y ScienceDirect en los últimos 10 años. Se han incluido 16 estudios de los cuales, el 37.5% se centra en trastornos de la alimentación. El abuso sexual, el físico, la violencia intrafamiliar, el acoso escolar y la suma de diferentes experiencias adversas vitales identifican pacientes con sobrepeso y alta insatisfacción corporal. El abuso emocional se ha asociado a bajo peso y preocupación entorno a la figura. La relación con la imagen corporal está mediada por clínica postraumática y la desregulación emocional. La clínica alimentaria es una respuesta a un mal manejo de emociones negativas derivadas de diferentes experiencias adversas y este mecanismo podría estar en la base de la insatisfacción corporal de los pacientes.
Palabras clave: trastornos de la alimentación; experiencias adversas vitales; bulimia nerviosa; anorexia nerviosa; trastorno de atracón; imagen corporal; insatisfacción corporal; eventos traumáticos.
A 10 nation exploration of trustworthiness in the workplace
Authors: Kwantes Catherine T. , Kartolo Arief B.
Published: December 2021

In the context of the workplace, and especially in today’s often fast-paced, cross-cultural and virtual work environment, a basic type of trust—“swift trust”—forms quickly based on cognitive processes and beliefs, or stereotypes, of another. Interpersonal trust is in large part based on these contextualized assessments of the extent to which another person is trustworthy. While trust across cultural boundaries has been examined, there is a lack of research investigating how trustworthiness is determined cross-culturally, especially with respect to what heuristics are used in the development of trust. The current project explored how trustworthiness is conceptualized and described for both colleagues and supervisors across 10 nations using the Stereotype Content Model. Qualitative descriptors of trustworthy supervisors and colleagues were coded based on the importance ascribed to warmth and competence, and these codes were used as the basis for cluster analyses to examine similarities and differences in descriptors of role-based trustworthiness. Both differences and similarities in the expectations of trustworthiness were found across the national samples. Some cultures emphasized both warmth and competence as equally important components to developing trustworthiness, some emphasized only warmth, while others emphasized only competence. Variations of trustworthiness stereotypes were found in all but two national samples based on role expectations for supervisors and colleagues. Data from the GLOBE project related to societal cultural practices and cultural leadership prototypes were drawn on to discuss findings.
A cena americana de Mary Overlie e a origem do Six Viewpoints
Authors: Rinaldi Miriam
Published: December 2021

Em maior ou menor grau, a improvisação é elemento inerente das artes cênicas. No entanto, os conceitos que orientam a construção de enunciados de improvisação refletem os valores e os conceitos de sua época. O Six Viewpoints, sistema de improvisação articulado por Mary Overlie, foi tornado público em 1978 e desde então veio se consolidando, e hoje participa da formação de muitos artistas no Brasil. Sua origem, no entanto, não está dissociada de suas circunstâncias históricas. Nesse artigo de caráter biográfico, buscou-se a conexão entre a prática e a teoria, desenhando alguns traços da trajetória da artista Mary Overlie desde sua infância em Montana até 1980, em Nova Iorque.
Tradições Inventadas e Criação de Espaço de Pertencimento: Uma revisão de literatura
Authors: Santos Adailson Costa dos , Veloso Jorge das Graças
Published: December 2021

O presente trabalho teve como intuito apresentar as ideias iniciais que estão sendo desenvolvidas em uma pesquisa realizada no âmbito do Doutorado em Artes Cênicas da UNB. A pesquisa teve como objetivo expor as concepções da Festa dos Bonecos Gigantes, que acontecem no município de Taquaruçu, no Tocantins, para defender a hipótese de que a mesma se constitui como uma tradição inventada, a qual foi pensada com o intuito de designar um espaço de pertencimento até então inexistente para seus fazedores. Aqui, foram discutidos conceitos de diversos campos de conhecimento para fundamentar primeiro o conceito de pertencimento enquanto uma instituição ontológica e inerente ao ser humano em sociedade. Posteriormente, foi discutido o conceito de tradições inventadas, e por fim, apresentado o lócus de pesquisa e a afetação deste trabalho: a festa supracitada. É possível compreender a Aldeia TabokaGrande como um espaço inventado para se sentir pertencente.

A partir de relações contínuas entre os aspectos internos e externos, objetivos e subjetivos da criação vocal, o artigo aborda a imensidão da experiência poética, Corpo Sonoro, em laboratórios de experimentação e de composição teatral e provoca um pensamento sobre técnica e dramaturgias plurais entre as práticas de pesquisa e pensamentos foucaultianos e bachelardianos sobre o(s) tempo(s), o(s) espaço(s) e o Corpo.
A reappraised tragedy: Lazzaro, by Francisco Pereira da Silva
Authors: Bodnar Roseli , Hohlfeldt Antonio Carlos
Published: December 2021

This article approaches the play Lazzaro (1948), one of the first works by playwright Francisco Pereira da Silva, born in Piaui, Brazil, in which he uses the genre intermezzo interlaid in an essentially tragic work, in order to discuss its dramatic function in it. The play here analyzed presents many connections with the tragedy Electra in the versions of both Sophocles and Euripides. But while in the Greek plays Orestes is not an instrument of blind fate since he acts as his father’s conscious avenger and his sister’s protector, in Pereira da Silva’s work the text is a little more complex because it is mixed with other texts, be it with different Greek myths or other textual inspirations such as the New Testament. It suffices to pay attention to the character’s given name that is also the title of the play. Besides, in the Brazilian playwright’s work we find the transposition of the original myth to the home of a decaying family in Northeastern Brazil.
LOS PLANES DE MODERNIZACIÓN, MEJORA E INCREMENTO DE LA COMPETITIVIDAD DE PRIMERA GENERACIÓN DE CANARIAS: UNA APROXIMACIÓN ANALÍTICA DESCRIPTIVA
Authors: Ledesma González Oswaldo , García Cruz Juan Israel
Published: December 2021

Dentro de la política turística en Canarias, los Planes de Modernización, Mejora e Incremento de la Competitividad se posicionaron como un instrumento fundamental para la renovación de las áreas turísticas. Planteado como un híbrido entre un plan estratégico y un instrumento de ordenación urbanística, su regulación insta a la concreción de un modelo turístico para el ámbito de actuación sobre el que interviene. No obstante, al menos los de primera generación, centrarían la renovación en la intervención física, dejando al resto de operativas en un segundo plano. El presente trabajo tiene tres objetivos: exponer las características generales de los planes; realizar una clasificación de los planes en función del momento de elaboración y aprobación, considerando el marco normativo vigente en cada momento; y realizar un estudio pormenorizado de los planes de primera generación, como caso práctico con mayor recorrido, a fin de evidenciar el peso que la operativa urbanística ha tenido en ellos en detrimento de otras operativas.

Within the tourism policy in the Canary Islands, the Plans for Modernization, Improvement and Increase of the Competitiveness were positioned as a fundamental instrument for the renovation of tourist areas. Posed as a hybrid between a strategic plan and an urban planning instrument, its regulation urges the concretion of a tourism model for the field of action on which it intervenes. However, at least the first generation, would focus the renovation on physical intervention, leaving the rest of operations in the background. The present work has three objectives: expose the general characteristics of the plans; make a classification of the plans according to the time of elaboration and approval, considering the regulatory framework in force at each moment; and carry out a detailed study of the first generation plans, as a longer case study, in order to demonstrate the weight that the urban planning operation has had on them to the detriment of others operation.
MODELOS DE PREDICCIÓN PARA EL SECTOR TURÍSTICO ANDALUZ MEDIANTE MÉTODOS ESTADÍSTICOS AVANZADOS
Authors: Sánchez Sánchez Francisca J. , Sánchez Sánchez Ana M.
Published: December 2021

En el trabajo se modeliza la serie temporal “turistas que visitan Andalucía”, variable que presenta una fuerte componente estacional. Se plantea y analiza la capacidad predictiva de tres modelos diferentes, aplicando distintas metodologías de modelización (Box-Jenkins, Holt-Winters y métodos combinados). Se comparan los resultados obtenidos de las predicciones con los valores reales de la serie de turismo, valorándose la buena capacidad predictiva de las tres metodologías empleadas. Se comprueba que el procedimiento clásico de Holt-Winters es el que ofrece mejores resultados predictivos.

In the work, the time series "tourists were visiting Andalusia" is modeled, a variable that has a strong seasonal component. The forecasting capacity of three different models is considered and analyzed, applying different modeling methodologies (Box-Jenkins, Holt-Winters and combined methods). The results obtained from the predictions are compared with the real values of the tourism series, assessing the good forecasting capacity of the three methodologies used. It is verified that the classic Holt-Winters procedure is the one that offers the best predictive results.
