Continuidad cultural entre las familias camanchaco-chango paposinas durante los siglos XVIII y XIX, a través del análisis de la categoría social del “agregado”
Authors: Castelleti D. José
Published: October 2019

Significant ethnographic information rescued by the paposins researchers Lazo and Gutiérrez (Lazo y Téllez, 1984; Gutiérrez y Lazo, 1996), allows to interpret the historical conditions that have defined the Camanchaca or Chango families of the Paposo/Taltal coast during the XVIII and XIX centuries, with the presence of the social and parental category of the "aggregates" or "relatives", subjects coming from the southern Altiplano or from other coastal groups, who were integrated into the local families from "compadrazgos" or commercial relationships (Larraín and Bugueño, 2011). The configuration of behaviors or habitus is discussed here (sensu Bourdieu, 1980), which this category of the "aggregate" would have generated among the Camanchaca or Chango families, also discussing how much of this social landscape is related to moments of contact and pre-hispanic, defining cultural continuity. To this end, such categorizations have been critically tracked between the material and oral information sources related to the Camanchaca/Chango occupation, in order to evaluate their probable causes and the way in which local and non-coastal individuals articulated themselves in the increasing exchange of charquecillo from pre-hispanic times, specialized behavior that will be marketed by the spanish crown and later by the national states.
Catch 22 — improving visibility of women in science and engineering for both recruitment and retention
Authors: Fogg-Rogers Laura , Hobbs Laura
Published: October 2019

There is a significant under-representation of women in STEM which is damaging societal progress for democratic, utilitarian, and equity reasons. However, changing stereotypes in STEM requires a solution denied by the problem — more visible female role models. Science communicators are critical to curate the conditions to bypass this Catch 22. We propose that enhancing self-efficacy for female scientists and engineers to mentor others will generate more supportive workplaces. Similarly, enhancing self-efficacy for public engagement improves the visibility of diverse female role models for young girls. These social connections will ultimately improve the science capital of girls and other minorities in STEM.
INDICAÇÃO DE ALOCAÇÃO DOS CUSTOS EM PROJETOS DE DESPOLUIÇÃO: UMA ANÁLISE DAS BACIAS HIDROGRÁFICAS DOS RIOS IPOJUCA E CAPIBARIBE
Authors: Costa Gabriela Carine Brito , Ferreira Monaliza De Oliveira
Published: October 2019

O presente trabalho tem como objetivo analisar a alocação dos custos em projetos de despoluição para o Rio Ipojuca e o Rio Capibaribe entre os municípios com sede urbana nas respectivas bacias hidrográficas. Isto se faz necessário devido os altos custos ambientais, sociais e econômicos causados pela poluição destes rios, uma vez que, além de aumentar os custos de tratamento da água, há o impacto de externalidades negativas para os municípios com sede nestas bacias hídricas. Para a análise, foi utilizado o Valor de Shapley, que é derivado da teoria dos jogos cooperativos. A variável determinante para alocar os custos em projetos de despoluição foi o volume de esgoto não tratado referido à água consumida que cada município despejou nas respectivas bacias hidrográficas ao longo do ano de 2015. A análise realizada a partir dos dados obtidos pelo Valor de Shapley indicou que a dinâmica demográfica dos municípios é o fator que mais influi na poluição dos rios, devido principalmente ao crescimento demográfico desordenado, que dificulta a prestação dos serviços de saneamento. Resultado intrigante, especialmente para lugares com maior efetivo de lavanderias de jeans. Por outro lado, talvez a informalidade e quantidade de facções (pequenos fabricos realizados em casa) possam explicar melhor este resultado.

o autor apresenta inicialmente uma análise das operações demodalização enunciativa para, em seguida, deslocá-las para o plano da semióticanarrativa. Assim procedendo, passa a trabalhar com os efeitos de sentidopassionais que caracterizam o sujeito, defendendo o ponto de vista de que odesenvolvimento da teoria semiótica das modalidades conduz necessariamente àteoria das paixões. Salienta que o sujeito da paixão não se confunde com o sujeitodo fazer modalizado. Destaca, igualmente, que a dinâmica modal das paixões nãoestá inscrita nas estruturas modais, sendo mais um efeito de seu uso. Por essarazão, distingue modalização de modulação.
A IDENTIDADE LINGÜÍSTICA DA COMUNIDADE DE FALA: PARALELISMO INTERDIALETAL NOS PADRÕES DE VARIAÇÃO LINGÜÍSTICA
Authors: Guy Gregory
Published: October 2019

The basic sociolinguistic model for relationships between idiolects anddialects is the speech community, defined by shared linguistic features andattitudes and relatively high internal density of communication. Since thesedefinitions are relative, speech communities can nest and overlap, so that localsubdialects, sociolects, ethnic lects, and personal networks can form smallerspeech communities that share local traits and are locally high in communicationdensity, while still belonging to a broader speech community which shares widertraits, and whose internal communication density is high, relative to, say, othergeographic regions. In variation studies, it has long been assumed that some of theshared linguistic traits that define a community are certain constraints on variableprocesses. The conceptual problem that arises with this model is, how far areconstraints shared, and how much can they differ? If some constraint was due, forexample, to a universal process, then it would be expected to be shared by allspeakers of all speech communities, while at the other extreme, the existence ofidiosyncratic differences in language usage raises the possibility that at least someconstraints may differ for each individual. This paper takes a cross-dialectalcomparative approach. Two variable processes are studied in four communitiesdrawn from the VARSUL corpus, each with distinctive ethnic and sociolinguisticcharacteristics. A socially diversified sample of 8-12 speakers is investigated ineach community. The variables investigated include one syntactic process (nounphrase Agreement, NPA) and one phonological process (final -s deletion, SDEL).The constraints on NPA are mainly morphosyntactic in nature while theconstraints on SDEL are straightforwardly phonological. In each case, theconstraint effects are broadly similar across communities and speakers. Betweenspeakerdifferences within communities are mainly the result of either statisticalnoise (smaller sample sizes lead to larger differences), or of predictable socialdifferentiation (e.g. speakers with less formal education use more of the nonstandard variants.) And, strikingly, the main constraint effects are highlyconsistent across the different communities. The results generally lend support tothe model of Cedergren & Sankoff (1974), that "performance is a statisticalreflection of competence", and competence, here dealing with the knowledge ofwhat varies where, is powerfully shared across a language community.

Published: October 2019

Objective: To determine the perception the family has about the humane care in the Intensive Care Units of three Health Service Institutions in the city of Cucuta (Colombia). Materials and Methods: A quantitative cross-sectional descriptive study was performed with a sample of 220 family members that met the requirements of inclusion; for the recollection of the information, the instrument used was denominated Family perception about humanization in the intensive care units, designed and validated in Cucuta by students and teachers of VIII semester from the Nursing Program at the University Francisco de Paula Santander in 2016. To determine the liability the Cronbach’s Alpha was used, obtaining a value of 0.89. Results: The humane care perception by family members was moderate in 63% of the participants. The communication and information, emotional support and family participation were the highest rating categories, while coping and visits had the lowest ratings. Conclusions: The participants of the study perceive as moderate the humane care, since they relate this to the quality of the care provided, considering the evaluated categories in the research. On the other hand, the family members point out that they receive the necessary information and support to involve themselves in the care activities, allowing them for more interaction with the hospitalized familiar and the personnel.

Published: October 2019

A leptospirose é uma zoonose endêmica prevalente no Sudeste brasileiro. Assim, o objetivo desse artigo é analisar epidemiologicamente os casos dessa doença e desenvolver uma proposta de intervenção. Este é um estudo epidemiológico descritivo de dados coletados na plataforma TabNet, referentes aos casos confirmados de leptospirose em Belo Horizonte, de 2007 a 2017, baseados no ano do primeiro sintoma. A proposta de intervenção foi embasada na literatura científica e em diretrizes do Ministério da Saúde. Foram notificados 252 casos e 24 óbitos. Dos acometidos pela doença, 76,58% possuíam de 20-59 anos, 80,2% eram homens, 28.2% consideravam-se pardos e 54% eram residentes da área urbana. A incidência da doença relaciona-se ao relevo e aos fatores climáticos. A prevalência de homens está relacionada com a ocupação laboral, e o maior acometimento de pardos com as disparidades raciais existentes. Assim, são primordiais ações para orientação da população, diminuição dos reservatórios da doença  e manejo dos indivíduos com suspeita da doença. Portanto, torna-se necessária a orientação da população e a redução de roedores, além da utilização de um protocolo de atendimento para os suspeitos com leptospirose e o uso de tecnologias inovadoras para o diagnóstico, como o teste laboratorial point-of-care testing.

Thermal cycling behaviour of plasma sprayed NiCr-Al-Co-Y2O3 bond coat in thermal barrier coating system
Authors: Vencl Aleksandar , Mrdak Mihailo
Published: October 2019

The aim of this study was to investigate the thermal cycling behaviour of NiCr-Al-Co- Y O bond coating in thermal barrier coating system with ZrO -MgO as a top coating. 2 3 2 The coatings were deposited by atmospheric plasma spraying on stainless steel X15Cr13 (EN 1.4024) substrate. The used composite powder NiCr-Al-Co-Y O was mechanically 2 3 cladded, and the steel substrates were preheated to 160-180 ?C. The thermal cycling performance of the obtained bond coat and the effect of formed complex ceramic oxides of the Al O -Y O system were tested by heating to 1200 ?C and cooling in air to 2 3 2 3 160-180 ?C. The number of performed thermal cycles was 7, 32, and 79. The quality of the obtained coating, as well as its thermal cycling behaviour, was assessed through the microstructural analysis, microhardness and tensile bond strength measurements, and change in chemical composition and microhardness. The obtained results showed that the steel substrate, bond coat oxidation and interdiffusion at bond coat/substrate interface have a significant influence on changes in chemical composition and microhardness of the bond coat. The correlation between oxidation behaviour of NiCr- Al-Co-Y O bond coat and number of thermal cycles was also discussed.

Thermal behavior of a three phase isolation transformer under load conditions with the finite element analysis
Authors: Balci Selami
Published: October 2019

Transformers are generally designed to operate under the sinusoidal excitation and the method called classical design method is used in design process. Nevertheless, they have to operate under the partly or fully non-linear excitation because of the increasing amount of the non-linear loads such as rectifiers, electric motor drivers, compact fluorescent lamps, computers, etc. Non-linear loads cause abnormal temperature rise both in the core and in the windings of the transformer which are designed for sinusoidal excitation. Nowadays in the virtual environment provided by the electromagnetic design software, transformers can be easily modeled with the finite element method for any type of non-linear loads or excitations. In this study, 3-D electromagnetic and thermal modeling of the isolation transformer at a certain rated power level have been carried out. Then, the core and the winding temperatures of the transformer have been comparatively reported under the linear and non-linear load conditions. Besides, forced air-cooling method of the transformer has been tested with the CFD. This study has shown that, transformer temperature can be kept in the safe operating region in any type of load by deciding the fan speed providing the required air-flow according to the transformer temperature.

Authors: Sadiq Muhammad , Waqas Muhammad , Hayat Tasawar
Published: October 2019

A nonlinear mathematical analysis for non-Darcian magneto-viscoelastic
nanoliquid is elaborated in this research. Flow is caused by stratified
surface having permeable nature. The Robin's type boundary conditions are
imposed at moving surface. Brownian diffusion, heat source and
thermophoretic aspects are accounted. Complex systems are simplified through
the well-known boundary-layer concept which is subsequently transfigured to
ordinary ones via transformation technique. Furthermore the meaningful
physical variables arising in non-dimensional problems are elucidated via
graphs.
Valorization of non-balanced coal reserves in Serbia for underground coal gasification
Authors: Petrovic David , Kricak Lazar , Negovanovic Milanka , Milanovic Stefan , Markovic Jovan , Simic Nikola , Stamenic Ljubisav
Published: October 2019

In the name of a better and safer energy future, it is our responsibility to focus our knowledge and activities to save on imported liquid and gas fossil fuels, as well as coal on which energy security of Serbia is based. The rationalization in the use of available energy resources certainly positively affects economy and the environment of a country. This paper indicates motivations for the application of the underground coal gasification process, as well as surface gasification for Serbia. The goal is to burn less coal, while simultaneously utilizing more gas from the onsite underground coal gasification, or by gasification in various types of gas generators mounted on the surface. In both cases, from the obtained gas, CO2, NOx, and other harmful gases are extracted in scrubbers. This means that further gas combustion byproducts do not pollute the atmosphere in comparison with traditional coal combustion. In addition, complete underground coal gasification power requirements could be offset by the onsite solar photovoltaic power plant, which furthermore enhances environmental concerns of the overall coal utilization.
A JUSTIÇA CURRICULAR EM TEMPOS DE IMPLEMENTAÇÃO DA BNCC E DE DESPREZO PELO PNE (2014-2024)
Authors: Ponce Branca Jurema , Araújo Wesley B.
Published: October 2019

Este artigo é um dos frutos da pesquisa denominada A justiça curricular no século XXI, as políticas e os sujeitos do currículo, que pautou a Educação Básica no Brasil em diferentes regiões e redes escolares. É resultado da ampliação dos estudos que relacionam currículo e justiça social realizados no Grupo de Educação e Pesquisa em Justiça Curricular (GEPEJUC) e de análises do contexto brasileiro, que a passos largos tem aprofundado na vida escolar uma racionalidade neoliberal. A ela somaram-se drásticos cortes nos investimentos públicos, a partir de 2016, que têm impedido a realização de metas propostas pelo Plano Nacional de Educação (2014-2024), além da obrigação jurídica imputada pelo Estado brasileiro aos entes federados de implementar a Base Nacional Comum Curricular, homologada em 2017. Analisa-se o currículo escolar como território de disputa (ARROYO, 2013) e apresenta-se o conceito de justiça curricular em suas três dimensões – a do conhecimento, a do cuidado e a da convivência – utilizando-o nas análises dos recentes acontecimentos educacionais brasileiros e propondo-o como um dos instrumentos de resistência às tendências dominantes na medida em que, no currículo, se cultivem espaços de formação de subjetividades democráticas. Ressalta-se a urgência de ensinar na e para a democracia compreendida como um valor. A fundamentação teórica: em relação às proposições epistemológicas e políticas, contou com Santos (2007, 2011, 2018) e Freire (2001, 2011, 2014) e, em relação ao conceito de justiça curricular, contou com Santomé (2013), Connel (2009), Estevão (2001, 2004), Ponce e Neri (2015, 2019) e Ponce (2016, 2018).
POTENCIALIDADES DA TEORIA DO DISCURSO PARA ANÁLISE DA POLÍTICA CURRICULAR DE FORMAÇÃO DE PROFESSORES (1996-2006): DEMANDAS, ANTAGONISMOS E HEGEMONIA

Published: October 2019

Neste artigo discutimos a potencialidade da teoria do discurso para análise do debate da política curricular (1996-2006), considerando demandas, antagonismos e hegemonia. Trata-se dos resultados de uma pesquisa cujo objeto de estudo é o debate da política curricular de formação de professores e os sentidos do estágio supervisionado (1996-2006). Em consonância com a teoria do discurso, defendemos a tese de que o referido debate é um campo de articulação discursiva e de disputas hegemônicas de significação em torno de projetos de sociedade, educação e currículo para a formação de professores. Especificamente identificamos as demandas, os antagonismos e as disputas hegemônicas de significação nos documentos da Associação Nacional pela Formação dos Profissionais da Educação - ANFOPE, e analisamos os processos hegemônicos a partir da lógica da equivalência e da diferença nos documentos curriculares do Ministério da Educação/Conselho Nacional de Educação - MEC/CNE. Construímos um método de análise com base no arcabouço teórico da teoria do discurso de Laclau e Mouffe (1987), na perspectiva da problematização/desconstrução dos discursos, demonstrando como se opera a sua hegemonização.

Micrometric research results of vacuum dough divider components
Authors: Martynova E. G. , Velichko S. A. , Martynov A. V.
Published: October 2019

Introduction. Nowadays, vacuum-type dough dividers are used in industries with a production volume of up to 4,000 loaves per day. In the dough divider operation, due to wear of the working surfaces of the piston, chamber, and drum, the gap between them goes beyond the value equal to 50 microns, which provides vacuum in the suction chamber. As a result, the suction process becomes unstable; the dough divider disturbs the weight accuracy of bakery goods. Repair of such equipment is carried out mainly through a full or partial replacement of worn parts and assemblies with new ones. To increase their durability, there is a need to develop a new highly efficient technology with the restoration of worn part surfaces using the welding and surfacing methods.

Materials and Methods. A new technique of determining the number of objects for research using the “STATISTICA” program is presented. Wear surfaces of the vacuum dough divider parts are determined.

Research Results. Micrometric studies of the dough divider components were carried out. They showed the presence of appreciable size distortions due to the local wear of the working surfaces. In this case, a side gap between the suction chamber and the main piston and between the drum and the suction chamber is 6 times higher than the permissible one, and a vertical gap between the division box and the piston exceeds the permissible gap by more than 10 times. Wear of the working surfaces of the dough divider parts is local in nature, while the range of values is as follows: for the main piston, it is 10-200 microns; for the gaging piston, it is 250- 900 microns; for the suction chamber and division box, it is 300-400 microns; for the drum surfaces, it is 280-300 microns.

Discussion and Conclusions.The conducted micrometric studies showed the presence of appreciable size distortions due to the local wear of the working surfaces. Based on the results obtained, it can be argued that the most productive and economically viable technique for the restoration of worn surfaces of dough divider parts is, for example, the electrospark machining.

Determinants of Displaced Commercial Risk in Islamic Banking Institutions: Malaysia Evidence
Authors: Arshad Noraziah Che , Zakaria Roza Hazli , @ Mohamad Ahmad Azam Sulaiman , Irijanto Tubagus Thresna
Published: October 2019

Islamic banks are exposed to a unique risk such as Displaced Commercial Risk (DCR). DCR arises from the assets managed on behalf of the investment account holders which may be borne by the Islamic bank’s own capital, when the Islamic banks forgo part or all of its share of profits on the investment account holders funds, in order to increase the return to the investment account holders. In a dual banking system, DCR could be a threat to the Islamic banks given the competition of fixed and higher return from the conventional banks. However, DCR would not be a threat to Islamic banks if their account holders choose Islamic banks due to religious obligatory factor. Pertaining to this issue, this paper aims to identify the determinants of factors influencing the DCR among the Islamic banks in the case of Malaysia. Results of the study suggest that the DCR is significantly determined by the Investment account holder funds, Islamic deposit, rate of return, and interest rate.

In the present work, reduced graphene oxide/Titanium dioxide (rGO/TiO2) composites (1:1 and 1:2 wt %) have been synthesized by the hydrothermal method using graphene oxide (GO) and commercial TiO2 as precursors. Previously, we prepared the GO, in the way optimizing and making safer, the Hummers route. We have chosen the hydrothermal method to prepare the composites because it offers several advantages: 1) It consist of a very simple experimental setup, 2) it utilizes only water, instead of Hydrazine or Sulfonate used as chemical reductants in traditional methods, avoiding the incorporation of un-willing impurities into GO sheets, 3) the temperature and pressure condition reached in the closed hydrothermal system have promoted the recovery of π-conjugation after dehydration diminishing defects concentration and increasing the degree of reduction of the GO sheets, and 4) this system is compatible with industrial batch production. The structure, surface morphology, chemical composition and optical properties of GO, TiO2 and rGO/TiO2 composites have been analyzed using, TEM, FTIR, Raman- and XPS-spectroscopy. TEM micrographs show that the TiO2 nanoparticles are non-homogenously adsorbed onto the GO sheets. FTIR spectra of the rGO/TiO2 composites suggest that during the hydrothermal process the GO sheets get reduced. Raman spectra suggest that TiO2 remains with anatase structure even after the hydrothermal process. The C 1s XPS spectra of the rGO/TiO2 composites have shown a significant decrease of oxygenated carbon related signals, confirming that most of the oxygenated groups were successfully removed. Based on these characterization results we infer that, GO sheets of good quality have been successfully synthesized and the GO sheets have been partially reduced via the TiO2 nanoparticles anchored during the hydrothermal process.

As we are entering the 5G era, high demand is made of wireless communication. Consistent effort has been ongoing in multiple-input multiple-output (MIMO) systems, which provide correlation on temporal and spatial domain, to meet the high throughput demand. To handle the characteristic nature of wireless channel effectively and improve the system performance, this paper considers the combination of diversity and equalization. Space-Time trellis code is combined with single-carrier modulation using two-choice equalization techniques, namely: minimum mean squared error (MMSE) equalizer and orthogonal triangular (QR) detection. MMSE gives an optimal balance between noise enhancement and net inter-symbol interference (ISI) in the transmitted signal. Use of these equalizers provides the platform of investigating the bit error rate (BER) and the pairwise error probability (PEP) at the receiver, as well as the effect of cyclic prefix reduction on the receivers. It was found that the MMSE receiver outperforms the QR receiver in terms of BER, while in terms of PEP; the QR receiver outperforms the MMSE receiver. When a cyclic prefix reduction test was carried out on both receivers, it yields a significant reduction in BER of both receivers but has no significant effect on the overall performance.

Published: October 2019

Assessment of an educational program/course, based on quantitative data, is attempted in this study, by using the final deliverables of the trainees and assess them according to a predefined set of items connected to the desired Learning Outcomes and a predefined scale for each item. The statistical analysis of the items’ grades, first using factor analysis and then using an Item Response Theory model, gives an indication of the Learning Outcomes’ degree of achievement and consequently guides the training designers to modify training strategies for a potential next cycle of the training program/course. For this study, a teacher training course on flipped classroom methodology, has been used and the above concept was tested. Our analysis using Item Response Theory, revealed the Learning Outcomes partially or not at all achieved showing very good agreement with trainers’ intuitive observations. For the future, the use of such a quantitative assessment could involve Structural Equation Modelling (SEM) tools to assess the relations among learning outcomes, prior knowledge and teaching practices and temporal analysis during training course execution using not only final data but also data from intermediate phases.

Congestion is essentially a relative phenomenon that is linked to the difference between the roadway system performance that users expect and how the system actually performs. The approach to traffic congestion (TC) from the different perspectives of countries around the world helps Vietnamese experts to better understand and come up with a consensus on how to understand the problem. this topic. Since then, in the management of traffic safety and control, to curb traffic congestion, traffic police and other departments have the basis to perform the work, properly assess the level of traffic safety to implement the task; doing well the reporting, statistics, building databases on TC; create integration in the context of international cooperation with other countries. Solving the problem of traffic congestion in large cities in Vietnam is a problem that cannot be solved overnight. This problem requires the synchronous participation of many ministries, branches and people in traffic. All measures need to get feedback from the people, thoroughly resolve the critic before implementation. This article briefly presents the situation of traffic congestion in Hanoi and Ho Chi Minh City. The team also focused on analyzing the causes of traffic congestion and proposed solutions to solve this urban problem.

The cross-border trade cattle, involve the movement of several thousands of animals with the risk of introduction of zoonotic diseases and vector borne-diseases between the countries. It was during a trade transaction that a kuri beef (Bos Taurus) coming from the lake chad area in order to cover the needs in meat of the populations of Gabon has introduced Hyalomma impeltatum an anthropophilic tick. The risk of introduction in Gabon of pathogens such as the arbovirus Sindbis and Dhori; the virus of Crimea-Congo hemorrhagic fever, Rickettsia africae as well as Rickettsia aeschilmannii is a real threat for public health. The treatment of cattle with effective acaricides at the frontier before entering to Gabon can prevent the introduction of ticks and tick borne diseases.

Acinetobacter baumannii is a member of the ESKAPE pathogens, notorious for causing multidrug resistant nosocomial infections worldwide. Biofilm has an important role in its persistence and spread in hospital environment, as well as its multidrug resistance potential. The present study was aimed at finding out whether the strength of Biofilm formation varies with infection of different organs / system.  A total of 136 isolates of Acinetobacter baumannii were taken from a variety of samples. Strength of Biofilm formation, determined by Tissue culture plate method, was graded according to OD value in ELISA reader as nil, moderate and strong.  It was seen that association between variations in biofilm forming capacity depending on different sites of infection was statistically significant.  We suggest biofilm typing by this method for this pathogen, as a potentially feasible alternative in countries with cost restrained healthcare set ups. Moreover, biofilm typing report would be more meaningful to the clinicians as well.

Las diferentes contribuciones que componen este dossier comparten la preocupación por la política. Sin embargo a lo largo de las páginas que presentamos, la política no se concentrará exclusivamente en el ámbito predilecto de la historia institucional; por el contrario, las autoras la descubren en un conjunto de prácticas plurales que dotan de significación a la acción de los sujetos. La acción política se revela en la dialéctica con las condiciones materiales de las cuales es tanto producto como fuerza transformadora. Esa materialidad cobra vida en un espacio, en una identidad y en una forma organizativa que es la comunidad, en sus abigarradas expresiones
PARAMETRIC MODELLING OF CLASS II MECHANISMS APPLIED IN MOVABLE STRUCTURES
Authors: Pawlak-Jakubowska Anita
Published: October 2019

Movable engineering structures are an important topic of modern scientific issues connected with civil engineering. Working on solutions to these issues requires an interdisciplinary action in fields such as geometry, construction, machine theory and mechanics or automatics. The author work considers class II mechanisms in existing solutions that occur in moving engineering, such as retractable roofs and bridges. Movement realization has a major influence on the behaviour of the structure during displacement. The analysis of the movability of existing engineering objects supported by parametric modelling facilitates the study of movement and allows for new concepts of solutions. KEYWORDS: retractable roof, movable bridge, class II mechanisms, quadrangles.

FORM’S AGE
Authors: Oliveira Sousa Pinto Maria João de
Published: October 2019

The need to control Forms has been gradually becoming a 21st Century obsession, not only to architects but also among several other areas. The Form has to be perfect according to predefined stereotypes: bodies, cars, gadgets, buildings must have a perfect form to be loved. This deep control about all forms that surround us, make us part of an era that can be called Form’s Age.
Form’s control is a structural concern when it comes to architecture, and architects deal with it in their everyday work as it is its core since the first sketches until the building on site. Being able to control form is the core, as without it, architects aren’t capable of mastering it in order to make it buildable. The question is therefore how can form be controlled and designed to be constructed has it was effectively planned.
