Authors: Panelli Bruna Lula , Barros Mariana Boulitreau Siqueira Campos , Do Ó Débora Morgana Soares Oliveira , Monteiro Estela Maria Leite Meirelles
Published: October 2020

O estudo objetivou analisar o conhecimento e as percepções de agricultores em um assentamento rural pernambucano sobre cuidados básicos de bem viver na perspectiva da promoção da saúde após uma intervenção comunitária de letramento em saúde. Trata-se de um estudo quasi experimental, longitudinal, com abordagem quanti-qualitativa. Foi realizado um levantamento do conhecimento com um pré e pós-teste, através da estatística descritiva e medidas de hipótese. As percepções foram levantadas a partir do Discurso do Sujeito Coletivo (DSC). Observou-se associação estatística significante, p-valor de 0,041e 0,039, nas questões referentes a Infecções Sexualmente Transmissíveis e Saúde mental respectivamente, realizadas pelas técnicas de metodologia ativa de ensino. A partir das análises dos discursos foi possível observar o engajamento dos “promotores em saúde” na mediação social da vulnerabilidade pelo reconhecimento das intervenções e práticas educacionais, para o fortalecimento de suas vozes nas tomadas de decisões, e mudanças de comportamentos. A intervenção comunitária desenvolveu percepções empoderadoras a nível individual e coletivo, assim como no reconhecimento das potencialidades da comunidade.
Previdência social, trabalho e pessoa com deficiência
Authors: Macedo Alano do Carmo
Published: October 2020

Este trabalho é produto de nossa tese de doutorado e examina, no contexto contemporâneo de contrarreformas no âmbito da seguridade social brasileira, a aposentadoria do trabalhador com deficiência, a partir dos dados fornecidos pelo Instituto Nacional do Seguro Social. Pautamos a deficiência como resultado de uma produção social da sociabilidade regida sob a lógica do capital, em um país de capitalismo periférico e dependente, marcado pela superexploração do trabalho que resulta na intensificação dos mecanismos de extração da mais-valia, com políticas sociais, respeitadas as particularidades históricas estruturais, cada vez mais agudizadas pela focalização e seletividade no místico Estado de direito burguês. Verificamos que as taxas que negam são exponencialmente superiores as de concessão do benefício, tão afinadas ao esperado pela burguesia rentista que busca ampliar a mercantilização dos serviço sociais.

O artigo apresenta parte dos resultados de uma investigação relativa ao projeto de cooperação internacional, envolvendo Brasil e Portugal, referente às diferenças e similitudes entre as políticas familiares de conciliação entre trabalho profissional e o trabalho familiar direcionadas as famílias com chefia feminina. A partir de levantamento bibliográfico, a revisão sistemática da literatura na área, identificam-se pontos de aproximação e distanciamento entre os autores estudados, como: à discussão da implantação das políticas restritivas de cariz neoliberal e desigualdades entre homens e mulheres; o debate sobre centralidade da família nas políticas sociais nos dois países em análise; as diferentes concepções de famílias e os novos arranjos familiares que se mesclam com o antigo padrão de família patriarcal e, finalmente, aborda as dificuldades da mulher chefe de família em conciliar formação, trabalho profissional e trabalho familiar no atual contexto econômico.
Novas estratégias para velhas práticas na distribuição de verbas federais
Authors: Machado Rebel Zambrano
Published: October 2020

Este artigo propõe uma reflexão sobre o orçamento público impositivo, que, ao ser aprovado, pretende ressignificar o papel do Poder Legislativo nas decisões do orçamento e na redefinição do escopo de ações. Por outro lado, destaca-se que essa participação do Legislativo na definição parcial do orçamento da União estimula a continuidade das práticas políticas populistas e clientelistas que atendem os interesses do mercado, ou seja, dos prestadores de serviços ao Sistema Único de Saúde (SUS), usando-o como moeda de troca. O objetivo do artigo é ressaltar a interferência do orçamento impositivo à luz do planejamento e da organização das Redes de Atenção à Saúde (RAS) no SUS, apontando as contradições provocadas no processo. As Emendas Legislativas do orçamento impositivo assumem características de comprometimento eleitoral, respondendo a promessas de caráter político dos parlamentares para com seus eleitores e as regiões que representam, assim como a liberação pelo governo de recursos orçamentários e/ou contratação de cargos em comissão em períodos importantes de votações pelo Congresso. Aflora a reflexão necessária sobre as disputas e quanto à organização do sistema de saúde ser a partir da oferta e não da demanda, o que de certa forma, acaba privilegiando os níveis de atenção de maior custo e cristalizando antigas práticas de distribuição de sobejos, atendendo os interesses de mercado, que, na maioria das vezes, em nada impactam na saúde da população.

Authors: Mariatti Alejandro
Published: October 2020

O presente artigo tem como objetivo caracterizar o desenvolvimento do mundo do trabalho no Uruguai, analisando modalidades marcantes que definem uma época. Para isso, se estabeleceu uma periodização em torno das diferentes inovações que foram sendo incorporadas à produção e ao aproveitamento do trabalho. Este processo possui vinculação direta com o desenvolvimento do capitalismo monopolista até o presente momento. Pretendeu-se reproduzir os passos que permitem compreender o lento processo de precarização e empobrecimento dos trabalhadores a longo prazo. Por fim, a partir dessa trajetória se procurou estabelecer um cenário para situar a discussão em um contexto contemporâneo, com tendência à precarização do trabalho, à uberização e ao avanço do capitalismo de plataforma.

Published: October 2020

O presente artigo visa analisar o relato escrito por Carmen Oliver de Gelabert, intitulado Viaje poético a Petrópolis, para tanto, basear-nos-emos no paradigma da descrição na tradução etnográfica, isto é, a realidade social apreendida a partir do “ver”, transformada em linguagem; do esforço de transformar o olhar do viajante em escrita, segundo nos explica Laplantine (1996) e de sua relação com a tradução interlingual (FERREIRA, 2017; JAKOBSON, 2011), pois a realidade que está acontecendo em uma língua estrangeira está sendo transmitida ao leitor na linguagem da narrativa de viagem, no entanto, há sempre a presença de termos exóticos que podem aparecer no relato de maneira discreta ou destacada. Somado ao exposto, acrescentaremos as categorias de classificação e de tradução de culturemas elaboradas por Molina (2006; 2011), que nos levaram a perceber a domesticação do relato de viagem escrito por Carmen Oliver.

Published: October 2020

Anticoagulant rodenticides (ARs) are widely used to control rodents. A method based on online turbulent flow chromatography (TFC) combined with LC-MS/MS has been established for rapid quantitative determination of eight ARs in human blood and urine. This method, which does not require time-consuming pre-processing steps, renders it especially suited for use in emergency poisoning cases. Sample preparation, including extraction, centrifugation, and filtration, was followed by online clean-up using TFC. The total run-time was within 13.5 min, including online purification, chromatographic separation, and re-equilibration of the TFC system. The parameters for sample extraction, purification, separation, and detection in this study were optimized separately. The linear regression coefficients of matrix-matched calibration standard curves established for quantification were greater than 0.9976. The limit of quantification (LOQ) for the method were found to be 0.3–3.0 ng/mL in human blood and 0.06–0.6 ng/mL in urine. The recoveries of spiked target compounds at different concentrations in human blood and urine were 91.8–111.9% and 86.9–105.3%, respectively. Inter- and intra-day precision values were both less than 12.5%, and the matrix effects of human blood and urine samples for ARs were 75.3–108.6% and 102.7–130.0%, respectively. This method had successfully applied to the emergency detection of ARs in biological samples of poisoned patients.
THE COMPLIANCE CHALLENGES OF SMALL, MEDIUM AND MICRO ENTERPRISES IN SOUTH AFRICA
Authors:   Vaal University of Technology, South Africa, Madzimure Jeremiah
Published: October 2020

The Small, Medium and Micro Enterprises (SMMEs) play a crucial role in the development of South African economy through job creation and improving the standard of living. Despite their importance, majority of these SMMEs are facing compliance challenges. The study seeks to identify compliance challenges of SMMEs in terms of the company act and the impact on their ability to conduct business while remaining competitive and legal in South Africa. This study was conducted in Gauteng province of South Africa. The study applied a qualitative, interpretive approach. The thematic analysis through inductive process was used to analyze the interview responses collected from the participants. The main findings reveal that the uneven business environment has rendered the prosperity and growth of small business impossible. That impossibility is attributed to the lack of capacity and skill to comply with the burden of the company act, given the uneven ground of competition on which large enterprises are more experienced and resourceful. The value of this study is the proposed solution to the current compliance challenges which most SMMEs face and impede their growth. The study recommends that the government offer tax rebates and incentives for SMMEs.

Published: October 2020

The main purpose of this article is to make an extensive review on the sustainable supply chain management literature in order to find some implications to management accounting. It also aims to explain sustainability in supply chain management, the needs of a sustainable supply chain, historical development and importance of sustainable supply chains. As the first step, a keyword search was conducted in the well-known databases, and then, sustainable supply chain management (SSCM) studies, which have connections to and implications for management accounting are evaluated and summarized separately. Although SSCM literature is very rich, the number of SSCM studies which have implications to management accounting is scarce. They point out that management accountants may take parts especially in determining cost and profitability of sustainable products, cost and quality evaluation of input materials and risk evaluation of suppliers, developing costing models for sustainable production, measuring performance in economic, environmental and social areas, and making cost-benefit analysis in the implementation and adoption of sustainability in each steps of sustainable supply chains.

Authors:   Academy of Economic Studies of Moldova, Republic of Moldova, Calugareanu Irina
Published: October 2020

Enterprises in their classical form are complex and inflexible structures, unable to respond quickly to the environmental changes. At the same time, the existing national and international regulations and procedures limit their agility and velocity of work but are necessary for the existence of business settlements. We all know that such structures do not stimulate the creation and promotion of innovations that we all need, and that can lead not only to competitive advantage but also to the development of country indices. In this respect, the article aims to determine the influence of the Republic of Moldova economic development index by the joint ventures and stateowned enterprises’ investments. In the research, we use the documentation methods of statistical data and two linear regression unifactorial econometric models and the statistical procedure Least Squares Method. Investigation and description of this topic allow the author to generalize the main findings of the major influence of the enterprise’s investments on the economic and social development of the Republic of Moldova.

Indonesia mobile payment industry is growing organically especially since Indonesia is among the top 3 countries of internet users in Asia. Mobile payment has revolutionized the way we manage digital transactions and it offers a wide variety of payment facilities and benefits compared to cash, credit cards, debit cards or other payment methods. The effect of providing mobile payment users with numerous incentives, for example in the form of cashback, is a compelling factor to be investigated on mobile payments adoption in Jakarta, as various mobile payment operators intensively and continuously provide cashback as a means of customer attraction and retention. In this study, UTAUT2 was adapted to discuss the phenomenon that occurred and to compare the effect of providing incentives in mobile payment technology adoption versus the effect of other factors. Eight constructs from UTAUT2 model were carefully taken into this study, where the original constructs of UTAUT2, namely use behavior, behavioral intention, performance expectancy, effort expectancy, facilitating conditions, social influence and hedonic motivation, are maintained, while the construct of price value is adapted to become negative cost so that the present mobile payment industry can be applied more representatively. Despite the frequent practice of service providers giving incentives to customers and prospects, this study discovered that price value did not influence behavioral intention. Furthermore, behavioral intention is affected by performance expectancy, hedonic motivation and facilitating conditions, while use behavior significantly affected by behavioral intention.

Published: October 2020

In this study, a bimetallic catalyst consisting of Pt and Pd nanoparticles supported on poly(vinylferrocene), i.e., PtPd@PVF was electrochemically prepared on pencil graphite electrode to improve the catalytic properties of previously developed Pt@PVF catalyst. K2PtCl4 and K2PdCl4 were used as the metal precursors in order to disperse the Pt and Pd onto the conducting polymer support by cyclic voltammetry technique. Electrochemical and chemical reduction methods were compared for the reduction of Pt and Pd complexes. The prepared catalyst system was electrochemically characterized by cyclic voltammetry. Physical characterization of the catalyst was performed by recording scanning electron microscopy images and energy dispersive X-ray spectrum. The PtPd@PVF catalyst showed superior catalytic activity towards electrooxidation of methanol compared to the monometallic Pt/PVF catalyst.

Published: October 2020

Abstract: This cross-sectional study investigated the association between alcohol use by adolescents and the availability of alcohol outlets in the neighborhood of public schools. We collected primary data including variables at individual and school neighborhood level. Multilevel logistic regression was used to estimate odds ratio (OR) with a 95% confidence interval (95%CI) for alcohol use with the exposure variables. A total of 18.4% (95%CI: 13.2; 24.1) of adolescents reported using alcohol, which was associated with variables on the individual level such as being 18 years or older, working, and having previously smoked. Lower alcohol use was observed among adolescents from schools that were located 250m or more from alcohol outlets (OR = 0.29; 95%CI: 0.17; 0.48). Actions to reduce the use of alcohol among adolescents should take student’s and school neighborhood’s characteristics into account.
Numerical analysis of the thermal profile inside the wall of a rotary cement kiln
Authors: Silva P. H. G. da , Moreira J. , Costa A. O. S. , Costa Jr. E. F.
Published: October 2020

Abstract The present study aimed to evaluate the temperature profile along the inside of the wall of a clinker kiln from a cement industry. The problem was modeled by the equation of transient heat conduction in cylindrical coordinates, considering radial symmetry. Being the wall composed of different materials, even adopting constant physical properties, there is no analytical solution to the problem. The method of the lines was used, being the radial and axial directions discretized by finite differences and the resulting system of ordinary differential equations integrated in time until obtaining the temperature field in steady state. The obtained field was compatible with heat transfer fundamentals and presented a good fit in relation to industrial data. The main limitations of the modeling performed in this study include the fact that the gases and solids contained in the kiln have not been modeled, and the variation in thicknesses of the layers of the kiln wall has not been considered. The program developed in this study can be used to evaluate the performance of different refractories or to infer the refractory wear level from experimental kiln surface temperature profiles.

Published: October 2020

Abstract This study aimed to obtain ceramic filters with bactericidal action for water disinfection. For this, aqueous suspensions of montmorillonite K10 clay were prepared at concentrations of 48%, 50%, and 52%. Later, these were impregnated into polymeric sponges in order to form the ceramic skeletons by using the replica technique. The ceramic filters were submerged in nickel resins doped with 0.25 and 0.50 mol% silver. These resins were obtained by the Pechini method and heat-treated at 600 and 700 ºC for 2 h. Moreover, techniques such as X-ray diffraction, particle size analysis, scanning electron microscopy, energy dispersive spectroscopy, compressive strength, water absorption, and apparent porosity were used to characterize the filters, and their performance was analyzed by a bactericidal test. The bactericidal test results showed that the filters impregnated with the resin containing 0.50 mol% of silver promoted the total elimination of the Staphylococcus aureus and Escherichia coli bacteria.

Abstract Rice husk is an abundant waste at the Rio Grande do Sul, Brazil, and it can be used to produce pure silicon dioxide, which is the main component of bioglass-ceramics. The addition of compounds, such as SrO, can improve the biocompatibility of these biomaterials. Therefore, the goal of this paper was to use rice husk silicon dioxide as a cheap precursor to obtaining bioglass-ceramics of the system 50%SiO2-25%Na2O-(25-x)%CaO-x%SrO (mol%) by sol-gel and investigate its potential use as a biomaterial. Two samples (BGC blank and BGC-5%Sr) were synthesized and characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and elemental carbon analysis by the combustion method. Scanning electron microscopy (SEM) was used to investigate the morphology of the bioglass-ceramics, while MTT assay of cell viability was used for in vitro characterization. The obtained silicon dioxide was amorphous and presented a small carbon content. Also, the bioglass-ceramics showed main phases with Si, Ca, Na, and Sr on their structure. Both samples were not cytotoxic against peripheral blood mononuclear cells (PBMC), and the incorporation of 5% SrO improved biocompatibility.

A pandemia das imagens: retóricas visuais e biopolíticas do mundo covídico
Authors: Beiguelman Giselle
Published: October 2020

A pandemia do coronavírus é também uma pandemia de imagens proliferadas entre câmeras térmicas, a intimidade extrovertida em videoconferências, as projeções nas fachadas e as inúmeras reproduções da síntese computadorizada do vírus. Não menos significativas, no contexto brasileiro, são as imagens do Presidente Bolsonaro, cujas fotos expressam sua visão política do coronavírus, e as das escavadeiras abrindo as valas das vítimas que sucumbiram à doença. Neste artigo, algumas imagens marcantes do isolamento social durante a COVID-19 no Brasil são analisadas como enunciados das retóricas visuais constitutivas da experiência cultural do novo normal. Com base na metodologia de Didi-Huberman em Cascas, parte-se dos registros imagéticos para compreender o contexto pandêmico. Apoiado nas discussões de Barthes, Foss e Mateus sobre retóricas visuais, o artigo defende que é a partir do campo das invisibilidades das imagens, que se compreende a dimensão biopolítica da pandemia.

Authors: Pereyra Isabel , Bustos Patricia
Published: October 2020

Abstract Objectives: to identify trendand factors associated with adverse birth weight. Methods: cross-sectional design. The analysis uses the 2009-2015 Uruguay Perinatal Computer Systemdata on 303,625 newborns. Results: the prevalence of macrosomia (> 3,999g) has increased from 7.0% to 8.4%. The prevalence of low birth weight (LBW) (< 2,500g) decreased, standing at 6.6% in the last year. The factors that determines more possibilities of LBW were preeclampsia (OR = 4.80; CI95%= 4.57-5.05), inadequate controls (OR = 2.29; CI95%= 2.20-2.39), shorter duration of pregnancy (OR = 2.52; CI95%= 2.50-2.55), previous hypertension (OR = 2.11; CI95%= 1.96-2.27), hypertensive disease of pregnancy (OR = 1.82; CI95%= 1.74-1.90), low prematernal maternal weight (OR = 1.65; CI95%= 1.58-1.74). Macrosomia was associated with type 1 diabetes (OR = 2.21; CI95%= 1.86-2.61), Type 2 or Gestational (OR = 1.78; CI95%= 1.70-1.87), obesity maternal (OR = 2.33; CI95%= 2.24-2.43) and longer gestation duration (OR = 2.62; CI95%= 2.53-2.72). Conclusions: the LBW decreases while the macrosomia increases. The health and nutritional status of women at the beginning of pregnancy, pathologies of the last trimester, smoking, shorter duration of pregnancy and inadequate controls are associated with BPN. Overweight, obesity and metabolic diseases determine macrosomia.

Authors: Santos Lucas Ribeiro dos , Duarte Márcio Luís , Duarte Élcio Roberto , Figueiras Felipe Nunes
Published: October 2020

Abstract Introduction: polyorchidism is an unusual pathology, about 200 cases in the world literature. Case report: we reported a case of polyorchidism in a 16-year-old male patient diagnosed by ultrasound and confirmed by magnetic resonance imaging. Discussion: most of the cases presented, there is a supernumerary testis, but there are reports on more than three, up to five testicles with supranumerical gonads on both sides of the scrotum. The diagnosis is usually performed in late puberty, incidentally, with a painless scrotal mass or at the emergency room, presenting a testicular torsion of the whole hemiscrotum or supernumerary testisalone, and the differential diagnosis should be made with epididymal cyst and spermatocele, besides other extra-testicular masses (hydroceles, varicoceles, lipomas, tumors.) and para-testicular masses (hernias, scrotal calculi). After the initial clinical evaluation, ultrasound is the first line subsidiary exam. Magnetic Resonance Imaging is very helpful, just in case the ultrasound diagnosis is uncertain. The supernumerary testishave the same Magnetic Resonance Imaging characteristics as the normal testes (intermediate signal intensity on T1- weighted images and high signal intensity on T2-weighted images).

Published: October 2020

ABSTRACT Ahasverus advena (Coleoptera: Silvanidae) is a secondary pest of stored grains. It is a polyphagic and cosmopolitan species, with little information about its occurrence in the northern region of Brazil. This study was conducted to report the first occurrence of A. advena in corn grains in the city of Plácido de Castro, in the state of Acre, Brazil. In June 2019, the presence of A. advena under development was observed in a mass of corn grains. The identification was made at the species level using the available dichotomous keys. Since this is the first record of A. advena in corn grains in the city of Plácido de Castro, monitoring insects in the mass of corn grains is necessary to prevent the economic damages caused by A. advena to grains.

Published: October 2020

Resumo Para a juventude o espaço público urbano corresponde a um campo de sociabilidade e de criatividade, utilizado como palco para o desenvolvimento de práticas que se desenrolam fora da alçada das instituições e do adulto. A generalização da internet e dos dispositivos móveis teve impacto na forma como o espaço é hoje vivido e representado pelos jovens. Aquilo que tradicionalmente era entendido pelas ciências sociais como “culturas de rua juvenis” não pode ser hoje pensado como próprio apenas do espaço físico, posto que possui extensão virtual. Referimos, por isso, culturas de rua híbridas, que navegam entre o mundo offline e online. O artigo avalia essa matéria partindo de uma revisão da literatura e de dados de diversos projetos de pesquisa desenvolvidos ao longo da última década.

Resumo Pesquisadores de movimentos sociais têm investigado os motivos que levam a ação coletiva a tomar determinada forma em determinado recorte espaçotemporal. Tal problema foi abordado pela literatura a partir de diferentes conceitos e debates. O artigo analisa três dessas ferramentas conceituais, revisando, ainda, sua apropriação pela literatura nacional sobre movimentos sociais: repertórios, escolhas táticas e performances. Os autores argumentam, em primeiro lugar, que cada um desses conceitos e debates está relacionado a uma perspectiva analítica distinta que direciona essa problemática geral a problemas de pesquisa específicos. Sugerem, em segundo lugar, que sua apropriação pela literatura nacional foi desigual, privilegiando o conceito de repertórios. Por fim, defendem a ideia de que sua articulação é capaz de fornecer uma resposta complexa a essa problemática geral, contribuindo para a superação de dicotomias teóricas e de obstáculos impostos por

GABRIEL COHN E A ESCOLA PAULISTA DE SOCIOLOGIA
Authors: Brito Leonardo Octavio Belinelli de
Published: October 2020

Resumo O artigo retoma o processo formativo de Gabriel Cohn a partir de seu vínculo com a cadeira de sociologia I da Faculdade de Filosofia, Letras e Ciências da Universidade de São Paulo. Desse prisma, busca compreender a sua produção teórica inicial à luz das preocupações dos sociólogos reunidos no Centro de Sociologia Industrial e do Trabalho. Em especial, examinamos o artigo de Cohn na coletânea Política e revolução social, o seu mestrado e o artigo “Problemas da industrialização no século XX”. Em seu segundo momento, acentuando o processo de autonomização intelectual de Cohn, cuja marca teórica pode ser vista a partir da incorporação das temáticas frankfurtianas em seus trabalhos nos anos 1970 - como em sua livre-docência sobre Max Weber -, o artigo examina as reflexões de Cohn sobre a obra de Florestan Fernandes como um momento privilegiado da autorreflexão sobre a tradição intelectual na qual se formou.

ABSTRACT The objective of this study was to obtain data on the occurrence of Babesia bigemina e Anaplasma marginale in cattle with characteristic clinical signs of the disease, in different properties in western Santa Catarina. For this, 149 blood sample were collected and slides smears were done and the staining with the Romanowsky kind dye subsequently. Of the 149 samples surveyed, 78 (52.35%) were positive for A. marginale, 04 (2.68%) for B. bigemina, and 03 (2.01%) samples showed co-infection. All described cases occurred in adult animals, from two years old, with Holstein females the highest occurrence represented 119/149 (79.86%). Regarding the presence of ectoparasites, hematophagous flies were observed in all properties and ticks in 58/149 (38.92%) animals. The results showed a higher occurrence of A. marginale, evidencing the need to seek strategies of control and prevention by the veterinary professionals, especially in moments of greater occurrence of the vectors. The confirmation as from laboratory support by stained blood smears beyond being cheaper practical is a method that helping professionals identify the suspected cases etiology. Moreover, based on this information, we can promote the elaboration of prevention and treatment strategies based on simple and fast diagnostic techniques, focused on especific disease agents.

Authors: Borges Nerio , Pino Pérez Ramón
Published: October 2020

In this work we introduce a 3-valued logic with modalities, with the aim of having a clear and precise representation of epistemic states, thus the formulas of this logic will be our epistemic states. Indeed, these formulas are identified with ranking functions of 3 values, a generalization of total preorders of three levels. In this framework we analyze some types of changes of these epistemic structures and give syntactical characterizations of them in the introduced logic. In particular, we introduce and study carefully a new operator called Cautious Improvement operator. We also characterize all operators that are definable in this framework.

Published: October 2020

The influence of geogrid on the thermal expansion of reactive powder concrete (RPC) was experimentally investigated. Eighteen RPC prisms of dimensions 75 × 75 × 280 mm were tested at a temperature of 27 ± 4°C and a relative humidity of 50 ± 10% for 103 days. Triaxial geogrid having equilateral triangular openings with a side length of 35 mm was used as a reinforcement layer. The triaxial geogrid was placed at a depth of 37.5 mm from the surface of the RPC prism. Test results illustrate that the triaxial geogrid reinforcement significantly reduces the thermal expansion strains of RPC. In addition, the thermal expansion strains of RPC decrease with increasing the number of triaxial geogrid layers. The triaxial geogrid reinforcement could reduce the rate of thermal expansion of the RPC specimens compared with the unreinforced RPC specimens. An empirical equation was developed in this study for determining the thermal expansion strains of RPC reinforced with a single or a double triaxial geogrid layer.

Various mathematical expressions have been proposed to evaluate or check the lapped length in spliced bars subjected to tension in reinforced concrete members. In this work, 284 tests on spliced bars were assessed in an attempt to improve the previous formulas, with the aim of proposing a new model to predict the lapped length, the transverse reinforcement spacing and the bond stress distribution in concrete beams with different compressive strengths. A genetic algorithm was used to optimise the proposed formulation. For both normal- and high-strength concrete, different bond-stress profiles were developed to predict the resistance provided by bonded embedment. The results clearly show that the proposed bond stress profiles lead to a more accurate evaluation of the lapped length in spliced bars than the expression proposed by the American Concrete Institute.

This paper reports on a numerical study into the crack-dependent behaviour of a steel-plate girder bridge strengthened with carbon-fibre-reinforced polymer sheets. Progressive cracking, which represented fatigue-induced damage, was simulated from up to 10% of the girder depth. Finite-element analysis was used to evaluate the performance of the control, damaged and strengthened cases subject to standard US highway fatigue loading. The efficacy of polymer strengthening was also examined from a strength perspective, using the load factor rating method and the load and resistance factor rating method. Localised fatigue cracking caused a stress concentration along the girder and its progression rate was related to the degree of web fracture. The damage of the tensile flange was more influential in reducing the flexural capacity of the girder relative to damage of the web. The strengthening decreased the stress ranges, thereby increasing the fatigue life of the girder, and enhanced the maximum average daily traffic capacity. Reliability modelling indicated a transition in failure rates before and after 3% cracking in the girder, supporting the extended functional time resulting from strengthening.
HS2 railway, UK – the parliamentary process to Royal Assent
Authors: Lagerweij Lucy , Knight Simon
Published: October 2020

The parliamentary process for a hybrid bill incorporates aspects of both public and private bill procedures. The key differences from the process followed by normal government (i.e. public) legislation are a consultation on the environmental statement and select committee (SC) stages in both the House of Commons and the House of Lords. For the bulk of its time in parliament, which typically spans a number of parliamentary sessions and can even span a general election, a hybrid bill will be in SC in one house or the other. The bill for phase 1 of HS2 completed its passage through parliament faster than the bill for Crossrail had, despite being significantly more contentious both nationally and locally, and receiving nearly six times as many objections (known as petitions). By any objective measure, the promotion of the bill was a success. This paper will explain the process for passing a hybrid bill in generic terms, as well as expanding to refer to the specific processes undertaken by High Speed Two (HS2) Limited to manage the SC, stakeholders, costs and associated governance in its delivery of the High Speed Two (London–West Midlands) Act.
The long-term effects of climatic factors on radial growth of downy birch (Betula pubescens) and rowan (Sorbus aucuparia) in East Iceland

The aim of this study was to investigate the tree-ring growth of rowan (Sorbus aucuparia L.) and downy birch (Betula pubescens Ehrh.) in Ranaskógur, a forest in East Iceland, and to determine its response to climate factors during the past century. Tree-core samples were collected in September 2018 and from those a tree-ring width (TRW) chronology and a standardized tree-ring index (TRI) chronology were produced. A statistical analysis between the chronologies and monthly mean temperatures and total monthly precipitation was carried out. The study found that both species had similar radial growth during the past century. The growth of birch responded significantly positively to June and July temperatures, while rowan responded significantly positively to July and August temperatures. The growth of neither species was significantly affected by precipitation across the whole period. However, in the 1940s to early 1960s, rowan growth correlated significantly with June precipitation, and birch with April and May precipitation.

Background: The present study was to compare the potential impact of remifentanil-based propofol-supplemented anesthesia regimen vs. conventional sevoflurane-sufentanil balanced anesthesia on postoperative recovery of consciousness indicated by c) values in patients undergoing cardiac surgery.Methods: Patients undergoing cardiac surgery were randomly allocated to get the remifentanil-based propofol-supplemented anesthesia employing target-controlled infusion (TCI) of remifentanil and propofol (Group-PR, n = 15) or a balanced-anesthesia employing sevoflurane-inhalation and TCI-sufentanil (Group-C, n = 19). In Group-PR, plasma concentration (Cp) of TCI-remifentanil was fixed at 20 ng/ml, and the effect-site concentration of TCI-propofol was adjusted within 0.8–2.0 μg/ml to maintain BIS value of 40–60. In Group-C, sevoflurane dosage was adjusted within 1–1.5 minimum alveolar concentration to maintain BIS of 40–60, and Cp of TCI-sufentanil was fixed at 0.4 ng/ml. The inter-group difference in the time for achieving postoperative BIS > 80 (T-BIS80) in the intensive care unit was determined as the primary outcome. The inter-group difference in the extubation time was determined as the secondary outcome.Results: T-BIS80, was shorter in Group-PR than Group-C (121.4 ± 64.9 min vs. 182.9 ± 85.1 min, respectively; the difference of means –61.5 min; 95% CI –115.7 to –7.4 min; effect size 0.812; P = 0.027). The extubation time was shorter in Group-PR than in Group-C (434.7 ± 131.3 min vs. 946.6 ± 393.3 min, respectively, P < 0.001).Conclusions: Compared with the conventional sevoflurane-sufentanil balanced anesthesia, the remifentanil-based propofol-supplemented anesthesia showed significantly faster postoperative conscious recovery in patients undergoing cardiac surgery.

Published: October 2020

Background: Appropriate blood component transfusion might differ between intraoperative massive bleeding and traumatic massive bleeding in the emergency department because trauma patients initially bleed undiluted blood and replacement typically lags behind blood loss. We compared these two blood loss scenarios, intraoperative and traumatic, using a computer simulation.Methods: We modified the multi-compartment dynamic model developed by Hirshberg and implemented it using STELLA 9.0. In this model, blood pressure changes as blood volume fluctuates as bleeding rate and transcapillary refill rate are controlled by blood pressure. Using this simulation, we compared the intraoperative bleeding scenario with the traumatic bleeding scenario. In both scenarios, patients started to bleed at a rate of 50 ml/min. In the intraoperative bleeding scenario, fluid was administered to maintain isovolemic status; however, in the traumatic bleeding scenario, no fluid was supplied for up to 30 min and no blood was supplied for up to 50 min. Each unit of packed red blood cells (PRBC) was given when the hematocrit decreased to 27%, fresh frozen plasma (FFP) was transfused when plasma was diluted to 30%, and platelet concentrate (PC) was transfused when platelet count became 50,000/ml.Results: In both scenarios, the appropriate ratio of PRBC:FFP was 1:0.47 before PC transfusion, and the ratio of PRBC:FFP:platelets was 1:0.35:0.39 after initiation of PC transfusion.Conclusion: The ratio of transfused blood component did not differ between the intraoperative bleeding and traumatic bleeding scenarios.
A novel application of Transnasal Humidified Rapid Insufflation Ventilatory Exchange via the oral route in morbidly obese patient during monitored anesthesia care -	A case report -
Authors: Jung Jaewoong , Chung Yang-Hoon , Chae Won Seok
Published: October 2020

BackgroundTransnasal Humidified Rapid Insufflation Ventilatory Exchange (THRIVE) is used to improve oxygenation, with the added benefit of a smaller increase in CO2 if self-respiration is maintained with THRIVE. Despite these advantages, the use of THRIVE through a nasal cannula is limited in situations such as epistaxis or a basal skull fracture. CaseWe successful used THRIVE, through the oral route under general anesthesia with spontaneous breathing in a morbidly obese patient (weight, 148 kg; height, 183 cm; body mass index, 44.2 kg/m2) who received transnasal steroid injections due to subglottic stenosis. ConclusionsTHRIVE through the oral route may be an effective novel option, although further studies are needed.
Incidence of inadvertent intercostal or epidural spread during thoracic sympathetic ganglion block
Authors: Hong Ji Hee , Yi Seung Won , Kim Ji Seob
Published: October 2020

Background: Sympathetic blocks (SBs) have been used widely to relieve the symptoms of sympathetically maintained pain (SMP). The thoracic sympathetic ganglion is not separated from somatic nerves by muscles and connective tissue. The upper thoracic ganglion runs along the posterior surface of the vertebral column in close proximity to the adjacent epidural region. This anatomical difference leads to frequent epidural and intercostal spread in cases of thoracic SBs. The purpose of this study was to investigate the incidence of inadvertent intercostal and epidural injections during thoracic SBs.Methods: Twenty-two patients who were suffering from complex regional pain syndrome or lymphedema after breast cancer surgery were managed with two or three times of thoracic SBs. Therefore, injections of 63 thoracic SBs from 22 patients were enrolled in this study. An investigator who did not attend the procedure evaluated the occurrence of intercostal or epidural spread using anteroposterior fluoroscopic images.Results: The overall incidence of inadvertent intercostal or epidural spread of contrast was 47.5%. Among the inadvertent injections, intercostal spread (34.9%) was more frequent than epidural spread (12.6%). Only 52.5% of the thoracic SBs demonstrated successful contrast spread without any inadvertent spread. The mean difference in skin temperature between the blocked and unblocked sides was 2.5 ± 1.8ºC. Fifty-nine (93.6%) injections demonstrated more than 1.5ºC difference.Conclusions: Thoracic SBs showed a high incidence (47.5%) of inadvertent epidural or intercostal injection. Thus, special attention is required for the diagnosis of SMP or the injection of any neurolytic agent around sympathetic ganglion.
