INFLUÊNCIA DA PRECIPITAÇÃO PLUVIOMÉTRICA NOS VALORES DE REFLECTÂNCIA DA ÁGUA, NO RESERVATÓRIO PASSO REAL - RS
Authors: Peixoto Daniela Wancura Barbieri , Pereira Filho Waterloo , Guasselli Laurindo Antonio
Published: November 2022

O estudo tem por objetivo estabelecer a relação entre os índices pluviométricos da bacia de captação da área de estudo e as alterações nos valores de reï¬‚ectância da água do reservatório da UHE Passo Real. Foram utilizadas 11 imagens do sensor MODIS- TERRA a ï¬ m de compor um ano hidrológico. Os dados de precipitação são provenientes da Defesa Civil do Rio Grande do Sul, totalizando 31 estações pluviométricas distribuídas na bacia de captação. A análise estatística levou em conta o acúmulo de precipitação no período de 5, 10, 15, 20, 25 e 30 dias anteriores à passagem do satélite. A reï¬‚ectância da banda do vermelho (648 nm) foi relacionada com a precipitação na área de captação reservatório. Correlações signiï¬cativas foram veriï¬cadas entre a reï¬‚ectância da água e a chuva antecedente a passagem do sensor. O valor acumulado de chuva em 20 dias anteriores a imagem de satélite apresentou correlação de 0,88 com a reï¬‚ectância para o setor do rio Jacuí e 0,83 no setor do rio Jacuí-Mirim. As relações foram analisadas por compartimentos do reservatório deï¬nidos pela bacias de captação dos braços principais do reservatório, no entanto, o compartimento aquático deï¬nido pelo rio Ingaí apresentou a melhor correlação (0,83) que ocorreu com o acumulado de chuva no período de 25 dias. As imagens MODIS registram as chuvas ocorridas em um período de 20 dias antes da passagem do satélite. Especiï¬camente no compartimento do rio Ingaí este efeito ocorre para um período de 25 dias.

Published: November 2022

Apesar da diminuição das taxas de desmatamento na Amazônia, as queimadas têm aumentado devido à associação entre práticas de manejo da terra e aumento da frequência de estiagens mais intensas. No presente trabalho mensurou-se o tipo de uso e cobertura da terra que mais queimou em um ano de seca extrema (2010) em comparação com dois anos de precipitação normais (2008 e 2012). Em seguida foi avaliada a associação entre os focos de calor em ï¬‚oresta e quais os tipos de uso e cobertura da terra que mais inï¬‚uenciam na propagação do fogo para a ï¬‚oresta. A área de estudo selecionada foi o município de São Félix do Xingu - Pará. Os resultados obtidos demonstraram que a classe pastagem apresentou maior inï¬‚uência na proximidade com focos de calor em ï¬‚orestas. Além disso, o maior déï¬cit hídrico de 2010 contribuiu para a intensiï¬cação das queimadas associado às fontes humanas de propagação do fogo.

Authors: Siqueira-Gay Juliana , Giannotti Mariana Abrantes , Tomasiello Diego Bogado
Published: November 2022

Based on the recent literature relating transport service level and social exclusion, as well as perceptions about the capacity of the population to cope with the occurrence of ï¬‚ ood events, this paper identiï¬ ed the spatial pattern related to ï¬‚ ood risk and accessibility to urban facilities. For that, composite spatial indicator is developed and compared with socioeconomic data. The analysis shows the outskirts of the city with the most vulnerable places, with high levels of ï¬‚ ood risk and low levels of accessibility. Those regions with low level of accessibility and close to ï¬‚ ood prone areas are characterized by low income level as well as the low percentage of residents with sewage system.

Authors: Girolamo Neto Cesare Di , Fonseca Leila Maria Garcia , Körting Thales Sehn
Published: November 2022

Distinguishing Brazilian savanna physiognomies is an essential task to better evaluate carbon storage and potential emissions of greenhouse gases. In this study, we propose to evaluate the potential of texture features to improve the discrimination among ï¬ ve physiognomies in the Brazilian savanna: Open Grasslands, Shrubby Grassland, Shrubby Savanna, Savanna Woodland and Gallery Forest. Texture features extracted from RapidEye images and also from Spectral Linear Mixture Model components and Vegetation Index were evaluated. Results showed that texture features based on GLCM can reduce misclassiï¬ cation for Open Grasslands, Shrubby Grasslands and Shrubby Savanna classes.

Published: November 2022

In this work we investigated a method for noise removal on Landsat-8 OLI time series using CBERS-4 MUX data to improve crop classiï¬ cation. An algorithm was built to look to the nearest MUX image for each Landsat image, based on an user deï¬ ned time span. The algorithm checks for cloud contaminated pixels on the Landsat time series using Fmask and replaces the contaminated pixels to build the integrated time series (Landsat-8 OLI + CBERS-4 MUX). Phenological features were extracted from the time series samples for each method (EVI and NDVI original time series and multi sensor time series, with and without ï¬ ltering) and subjected to data mining using Random Forest classiï¬ cation. In general, we observed a slight increase in the classiï¬ cation accuracy when using the proposed method. The best result was observed with the EVI integrated ï¬ ltered time series (78%), followed by the ï¬ ltered Landsat EVI time series (76%).

Authors: Araujo Vitor Silva , Sluter Claudia Robbi , Camboim Silvana
Published: November 2022

Standardized urban maps are essential cartographic products to address the challenges of cities management. Brazilian NSDI (National Spatial Data Infrastructure) was created to facilitate geospatial data sharing and use, but its standards are not completely adapted for large scale mapping for urban areas. This work aims to propose a data models based on the existent standards to support the generation of reference maps at a large scale (1:2,000) that is logically consistent, standardized and aligned to the principles of the theory of Cartography. These characteristics allow the reference geodatabase to be maintained by several producers and shared among institutions. The results of this project are the geospatial database implemented for four municipalities in Paraná State, and a conversion model that enables the creation of topographic maps on a large scale with symbols deï¬ ned in previous research.
AVALIAÇÃO DO EFEITO DO DOSSEL VEGETATIVO NA ESTIMATIVA DA PERDA DO SOLO EM ÁREA DE VINHEDOS USANDO SIG
Authors: Viel Jorge Antônio , Rosa Kátia Kellem da , Hoff Rosemary
Published: November 2022

O presente trabalho avaliou o efeito do dossel vegetativo de vinhedos para estimativa da perda superï¬cial de solos. Este estudo integra técnicas de Sensoriamento Remoto e Sistema de Informações Geográï¬cas (SIG) para quantiï¬car e mapear a erosão do solo na região da Denominação de Origem (DO) Vale dos Vinhedos - Brasil. A aplicação da Equação Universal de Perda de Solos (EUPS) considerou fatores como tipo de solo, declividade, erosividade e uso da terra. Os produtos cartográï¬cos gerados foram conï¬rmados por observações em campo. A perda superï¬cial de solo média em vinhedos com dossel vegetativo foi de 388,33 kg/ha/ano, já a perda superï¬cial de solo média em vinhedos que não possuíam o dossel vegetativo foi de 935,67 kg/ha/ano. Comparativamente os cruzamentos realizados evidenciaram pouca diferença entre as classes, sendo a principal diferença observada entre a classe de 0 a 1 t/ha/ano. Em vinhedos com dossel vegetativo, esta classe apresentou perda de solo de 82 % da área de estudo, já para o método que não considerou o dossel vegetativo do vinhedo, esta classe apresentou 75 % da área de estudo, indicando diferença de 7 %, evidenciando uma perda de solo maior no período de dormência do vinhedo. A diferença entre os resultados dos modelos é ressaltada quando se analisa a classe com maior perda de solo, pois no cruzamento que desconsidera o dossel vegetativo do vinhedo houve um aumento de 4,92  km², representando 11 % da área de estudo. Esta avaliação demonstra que a diferença da condução dos vinhedos e o dossel vegetativo inï¬‚uenciam na perda superï¬cial de solo. Sendo assim, os resultados podem contribuir para o monitoramento de processos erosivos laminares e para medidas de conservação e planejamento ambiental em áreas onde se desenvolve a vitivinicultura.
CLASSIFICAÇÃO SUPERVISIONADA E SALDO DE RADIAÇÃO PARA DISCRIMINAÇÃO DE ALVOS DE SUPERFÍCIE NO ENTORNO DO RESERVATÓRIO DE ITAPARICA - PE
Authors: Dos Santos Pereira João Antonio , Tavares Junior João Rodrigues
Published: November 2022

Este trabalho visa associar a utilização de classiï¬cação supervisionada por meio do método da máxima verossimilhança e saldo de radiação aplicado segundo as metodologias indicadas no algoritmo SEBAL (Surface Energy Balance Algorithms for Land) em imagens provenientes de sensoriamento remoto com o propósito de observar como o processo de geração de mapas do uso do solo pode ser complementado ao serem implementados índices físicos na análise das classes predominantes da paisagem. Foram utilizados dados do sensor OLI/TIRS no Landsat 8, na região entorno do reservatório de Itaparica, localizado predominantemente no município de Petrolândia-PE, e objeto de estudo do projeto INNOVATE (Interplay Among Multiple Uses of Water Reservoirs via Innovative Coupling Substance Cycles in Aquatic and Terrestrial Ecosystems), que tem como principal interesse entender as relações entre as mudanças climáticas e as formas de uso da terra e dos recursos hídricos em ambiente semiárido. Foi observado que na classiï¬cação supervisionada houve confusão entre as classes de solo exposto e área urbana, assim como nas classes de agricultura irrigada e vegetação arbórea. Essa confusão é explicada pela similaridade espectral que esses alvos possuem. Neste sentido, o saldo de radiação apresentou bom desempenho em separar as classes de uso do solo escolhidas. Dessa forma, pode-se observar que a aplicação do saldo de radiação pode incrementar a geração de mapas de uso do solo, sabendo-se que esse índice tem capacidade de discriminar as classes de ocupação a partir de mais variáveis que apenas o valor do número digital do pixel.

Authors: Souza Leonardo Andrade de , Sobreira Frederico Garcia
Published: November 2022

A avaliação da composição e forma da rede de drenagem em uma bacia hidrográï¬ca permite a caracterização dos aspectos geométricos e de composição dos sistemas ambientais, possibilitando através de estudos comparativos de cenários utilizar os parâmetros como elementos de suporte à deï¬nição e elaboração de indicadores para a gestão ambiental. Nesse sentido, a análise dos atributos morfométricos da Bacia Hidrográï¬ca do Ribeirão do Carmo (BHRC) teve como pressuposto estabelecer as relações entre os parâmetros mensuráveis da bacia e os seus condicionantes. Já a avaliação do padrão de comportamento das chuvas intensas no interior da bacia foi realizada juntamente com a determinação do tempo de concentração, a partir do início de uma determinada chuva, para que toda a área da bacia hidrográï¬ca passe a contribuir com água para a vazão que se estabelece em seu exutório. Como análise ï¬nal foi cartografada a suscetibilidade à deï¬‚agração de processos de inundação ao longo da BHRC, a partir da utilização de métodos qualitativos baseados nos atributos morfométricos e na análise geomorfológica, e na superposição e atribuição de pesos para mapas de fatores, associados ao conhecimento especialista de campo.
MAPEAMENTO DO PERCENTUAL DE SOLO EXPOSTO EM ÁREA SUSCETÍVEL À DESERTIFICAÇÃO EM PERNAMBUCO, BRASIL
Authors: Soares Deivide Benicio , Nóbrega Ranyére Silva , Mota Filho Fernando de Oliveira
Published: November 2022

Apesar de o tema da desertificação ser estudado em âmbito internacional desde a década de 1970, o consenso sobre o assunto ainda é muito pequeno, especialmente quando se trata da definição dos indicadores de desertificação. Desde a realização da Conferência das Nações Unidas sobre Desertificação em 1977, em Nairóbi, no Quênia, os indicadores de desertificação constituem tema de estudos e discussões tanto no meio acadêmico/científico, quanto no meio técnico, representado pelas entidades governamentais. Dentre os indicadores de desertificação consensuados na atualidade estão os indicadores abióticos, representados pelos aspectos climáticos, edáficos e hídricos. Neste contexto o objetivo deste trabalho é identificar o percentual de solo exposto na superfície da bacia do Pajeú, maior bacia hidrográfica do Estado de Pernambuco, totalmente inserida na região semiárida, suscetível à desertificação. O solo exposto foi identificado mediante classificação supervisionada e calculando-se o índice de Vegetação por Diferença Normalizada (NDVI). Foi detectado solo exposto em 1,26% da bacia, enquanto que 20,61% da sua superfície está coberta por vegetação rasteira, pastagens e área urbana; 63,57% possui cobertura de caatinga aberta e; 14,48%, por vegetação densa e culturas irrigadas e de vazante.
Beyond ‘supply and demand’: Moving from skills ‘planning’ to seeing skills as endogenous to the economy
Authors: Allais Stephanie Matseleng
Published: November 2022

This article questions the notion of supply and demand of skills, and, accordingly, the rules and tools that have been developed for skills anticipation in South Africa. I argue that there is nowhere ‘outside’ of the economy where skills are produced. Rather, a society and an economy need to be seen as an organism, where skill formation is a complex set of moving parts. The concept of supply and demand is unhelpful to think about skill formation because it directs our attention towards specific moving parts in isolation from the broader factors that shape them. This explains why, despite the existence of extensive tools and institutions for skills anticipation, and numerous institutions for social dialogue and stakeholder engagement, researchers and policy-makers argue that South Africa has an inadequate supply of the skills that are needed in the workplace and concomitant skills mismatches. The article also presents more specific problems with the rules and tools, particularly in the way the systems and institutions for understanding labour market demand interact with the systems and tools for the supply of skills – especially those tools that govern and shape skills provision. It argues further that, whereas there are real problems with these rules and tools, and while they can certainly be improved, the broad goals that they are intended to achieve will not be attained even with better tools, but that different conceptual lenses are required instead.
An examination of the English curriculum in Technical and Vocational Education and Training colleges
Authors: Madileng Mary Mmatsatsi
Published: November 2022

This article is premised on the notion that the perceived lack of quality of curriculum delivery in the vocational education sector is probably due in part to a lack of understanding of the nature of knowledge in vocational education. The article outlines the nature of knowledge specified in the subject English offered in the Technical and Vocational Education and Training (TVET) colleges. The study followed the English curriculum message as it starts from the production field, where new ideas are created and modified to the recontextualisation field, where curriculum designers produce written curriculum documents. The findings indicate that the designers of the National Certificate (Vocational) English curriculum followed an outcomes-based approach in its design but that the content knowledge indicated is vague and unspecified. The curriculum cannot provide a basis against which content knowledge can be selected, as it does not give prominence to grounded content knowledge of the subject. Instead, it is more concerned with the competencies of the students. An analysis of this curriculum identifies its strengths and weaknesses and helps to identify gaps in the curriculum design in at least one curriculum in the TVET sector.
Antimigratory Evaluation from Curcumin-Derived Synthetic Compounds PGV-1 and CCA-1.1 on HCC1954 and MDA-MB-231 Cells
Authors: Novitasari Dhania , Meiyanto Edy , Kato Jun-ya , Jenie Riris Istighfari
Published: November 2022

Earlier findings reported the anticancer-mediated activities of curcumin-modified compounds Pentagamavunone-1 (PGV-1) and Chemoprevention Curcumin Analog 1.1 (CCA-1.1) with several mechanisms including cell cycle arrest, reactive oxygen species (ROS) production, and cell migration disruption. Our study aims to evaluate the antimigratory activity of PGV-1 and CCA-1.1 on aggressive breast cancer cell lines (MDA-MB-231 and HCC1954 cells) and their effect on HER2 protein. The trypan blue exclusion method was conducted for the antiproliferative effect. The PGV-1 or CCA-1.1 effect on cell migration was determined by wound healing assay. Using gelatin zymography, we checked the secretion level of matrix metalloproteinase (MMP). We also evaluated the human epidermal growth receptor-2 (HER2) level after incubation with PGV-1 or CCA-1.1 in HCC1954 cells by western blot. Based on the antiproliferation assay, MDA-MB-231 and HCC1954 cells were sensitive to PGV-1 and CCA-1.1. MMP-2 was only observed in HCC1954 cells while MMP-9 was only observed in MDA-MB-231. Both PGV-1 and CCA-1.1 significantly suppressed MMP-9 activity in MDA-MB-231 cells. Moreover, PGV-1 inhibited HER2 protein levels in HCC1954 although it was not significant, whereas CCA-1.1 did not affect HER2 protein. This study strengthens the scientific evidence for PGV-1 and CCA-1.1 activities for future exploration as candidate chemotherapy with multitarget against breast cancer.Keywords: Curcumin analog, cell migration, MMP-9, HER2, breast cancer.

Published: November 2022

COVID-19 is a novel disease with multisystem involvement, but most patients have pulmonary and cardiovascular involvement in the acute stages. The cardiovascular impact of acute COVID-19 is well recognized and ranges from myocarditis, arrhythmias, and thrombotic occlusion of coronary arteries to spontaneous coronary artery dissection and microthrombi in small coronary vessels on autopsy. We report a case of a 37-year-old man who recovered from mild COVID-19 only to present a few weeks later with devastating cardiovascular involvement that included severe left ventricular impairment resulting from nonischemic cardiomyopathy, multiple left ventricular thrombi, and embolic stroke.

Published: November 2022

Minimally invasive aortic valve replacement through a right thoracotomy is frequently performed in patients with aortic valve disease. The Cor-Knot Device (LSI Solutions) is an automated fastener that secures valve sutures.

This case report is for a patient who developed postcardiotomy shock during a minimally invasive aortic valve surgery. The patient was found to have an aortic root dissection involving 90% of the aortic root circumference, including bilateral coronary ostia. The autopsy revealed that the aortic damage could be explained by a direct aortic intimal tear from the distal tip of the device shaft. The device was most likely not in perfect apposition to the sewing ring because of the restricted angle and space between the ribs.
Short-Term Results on Leaflet Mobility in Patients Undergoing Rheumatic Mitral Valve Repair With an Efficient 4-Step Commissuroplasty Technique

Published: November 2022

Background

Mitral valve stenosis (MS) is the primary pathologic feature of rheumatic mitral valve disease, and the complex repair affects its clinical outcome. This study aimed to examine the efficacy of the 4-step commisuroplasty “SCORe” procedure by assessing changes in the mobility of mitral valve leaflets and its clinical effects.

Methods

From September 1, 2018, to January 13, 2019, patients with MS who underwent mitral valve repair with the SCORe procedure in the study center were analyzed in this prospective study. Mitral valve structure was assessed by transthoracic echocardiography pre- and postoperatively as well as during follow-up.

Results

In total, 60 consecutive patients were examined. In 56 patients (93.3%), mitral valve orifice area (MVOA) was less than 1.5 cm2, and mean (SD) MVOA for the whole cohort was 1.20 (0.34) cm2. The mobility of the anterior leaflet was improved (P < .001) during the cardiac cycle postsurgery, but that of the posterior leaflet was not (P = .591). The mean (SD) coaptation length was increased significantly from 6.69 (1.32) mm to 7.92 (1.24) mm (P < .001) postoperatively. Mean (SD) MVOAs increased to 2.24 (0.38) cm2 postoperatively (P < .001). During the 1-year follow-up, there were no deaths or reoperations. Follow-up echocardiography revealed minor or mild regurgitation in 98.3% of patients.

Conclusion

These findings demonstrated that the SCORe procedure can effectively improve the mobility of mitral leaflets and enlarge the valve orifice area in patients with rheumatic MS in China, with minimal complications and promising results.
Identification of crucial salivary proteins/genes and pathways involved in pathogenesis of temporomandibular disorders
Authors: Talian Ivan , Laputková Galina , Schwartzová Vladimíra
Published: November 2022

Temporomandibular disorder (TMD) is a collective term for a group of conditions that lead to impairment of the function of the temporomandibular joint. The proteins/genes and signaling pathways associated with TMD are still poorly understood. The aim of this study was to identify key differentially expressed salivary proteins/genes (DEGs) associated with TMD progression using LC-MS/MS coupled with a bioinformatics approach. The protein–protein interaction network was obtained from the STRING database and the hub genes were identified using Cytoscape including cytoHubba and MCODE plug-ins. In addition, enrichment of gene ontology functions and the Reactome signaling pathway was performed. A total of 140 proteins/genes were differentially expressed. From cluster analysis, a set of 20 hub genes were significantly modulated: ALB, APOA1, B2M, C3, CAT, CLU, CTSD, ENO1, GSN, HBB, HP, HSPA8, LTF, LYZ, MMP9, S100A9, SERPINA1, TF, TPI1, and TXN. Two enriched signaling pathways, glycolysis and gluconeogenesis, and tryptophan signaling pathway involving the hub genes CAT, ENO1, and TPI1 have been identified. The rest of the hub genes were mainly enriched in the innate immune system and antimicrobial peptides signaling pathways. In summary, hub DEGs and the signaling pathways identified here have elucidated the molecular mechanisms of TMD pathogenesis.
Conspiracy Theories in Congregations: A Pastoral Response
Authors: Hussey Ian
Published: November 2022

Interest in understanding and responding to conspiracy theories has exploded in recent years. This article seeks to engage with a range of scholarship utilizing a practical theological methodology in order to discern an appropriate response. Because conspiracy theories often produce division in congregations, as well as isolate the conspiracists from their faith community, responding in a wise manner is clearly important. This article first surveys some of the theory and research related to the topic and then discusses the connections between religion and conspiracy theories. It then moves to recommend that a “pastoral” response, including a focus on caring and maintaining sense of belonging, is preferred to a rationalist response, aimed at convincing the conspiracists that they are wrong.
Creativity Unleashed: Building a Practical Theology for Christian Leadership in a World in Flux
Authors: Csinos David M.
Published: November 2022

Discourse surrounding Christian leadership is often influenced by colonialistic assumptions and theology that centralizes the role of the leader as change agent. In this article, the author uses Gordon Kaufman’s conception of God as serendipitous creativity as a resource for moving toward a practical theology of leadership that acknowledges colonialistic undercurrents within leadership discourse and responds to the shifting place of the church in our world. Naming God as uncontrollable, unplanned creativity engenders practices of Christian leadership that focus on the power of the community, discern divine creativity in one’s midst, and embrace the mysterious emergence of new realities.
Revisiting chronic low back pain: evidence that it is not non-specific
Authors: Nicodemus Clarence L. , Sikorskii Alla , Epstein Jessica
Published: November 2022

Context

There is a common symptom pattern with most chronic low back pain (CLBP), suggesting that there is a common underlying etiology, belying the term “nonspecific.” Many studies of CLBP and its treatment have been conducted with the assumption of nonspecificity, and as a result, treatment has not been focused, thus there has not been a significant change in CLBP prevalence over the past several decades. It is the thesis of this study to show that there is an underlying, specific cause of CLBP and that the presumption that CLBP is nonspecific is misdirected. The lumbosacropelvic (LSP) region, including the sacroiliac joint (SIJ), is part of a neuromusculoskeletal (NMSK) feedback system, and it is proposed here that CLBP is the result of a change in the feedback (afferent) aspect in that system.

Objectives

The objectives of this study are to show that CLBP presents as a pattern of symptoms that actually represents the final common pathway for a dysfunctional LSP joint system. Rather than being “nonspecific,” the majority of CLBP has an underlying cause that is quite specific and predictable.

Methods

A total of 252 patients were seen for CLBP, 67% of whom were diagnosed with an SIJ dysfunction. The presence of pain was recorded from seven structures most closely associated with CLBP. The conditional probabilities of having each pain generator given a SIJ dysfunction and an SIJ dysfunction given the presence of the pain generator were estimated, and associations were analyzed utilizing chi-square tests. Phi coefficients and odds ratios were utilized to quantify the strength of the association. The multivariable logistic regression model was fit to relate the presence or absence of the SIJ dysfunction to the seven pain generators.

Results

The associations between SIJ dysfunction and each pain generator were statistically significant. Phi coefficients indicated moderate strengths of these bivariate associations. Iliolumbar ligament (ILL) and psoas muscle (PSM) were significant predictors of SIJ dysfunction in the multivariable model.

Conclusions

Seven pain generators had a strong association with SIJ dysfunction. This empirical clinical evidence supports our hypothesis that LSP system dysfunction, as evidenced by SIJ dysfunction, is a common source of symptom patterning associated with CLBP and is most likely the causal element. This is evidence that most CLBP is not “nonspecific” but rather the result of changes made by the NMSK control system for the LSP region.
A study on forming limit diagram and laminated stamping of paperboard
Authors: Gao Ying , Li Yajie , Ji Zhong , Zhang Cunsheng , Lu Guoxin , Liu Ren
Published: November 2022

Coated paperboard not only has the advantages of traditional paper such as low density and cleanliness, but also overcomes its disadvantages such as poor barrier performance and sensitivity to moisture. It is more and more widely used in forming packaging containers. The current research on mechanical performance and inelastic deformation of paperboard mainly focus on its physical properties and simplified single-blank forming, but the studies on the forming limit diagram (FLD) of paperboard are relatively rare. In this paper, Nakajima tests have been carried out to determine the FLD curves of the polyethylene-coated paperboard blank along the machine direction, cross direction, and diagonal direction. A laminated stamping method for multi-blank is proposed and investigated by experiment and numerical simulation. Up to 5 blanks can be overlapped and stamped in a single punch stroke, and 5 bowl-shaped packaging containers can be formed simultaneously. Compared with the single-blank stamping process, the production efficiency can be greatly improved, but the flange area of the forming parts is easier to wrinkle. However, the wrinkling risk can still be controlled by optimizing the process parameters, such as friction factor and blank holder gap.
The Landscape Gouache
Authors: Schwahn Wolfgang
Published: November 2022

This article gives an overview over the development of gouache painting – from Flemish Waterverfschilderij, Lenten cloths (tüchlein paintings), miniature paintings, and landscape gouache in “heroic” and “rustic” styles to the landscape veduta of Alpine sceneries. The – often confusing – usage of the term gouache will be discussed and traced back in history, leading to a clear definition of our present-day conception. The findings are based on the study of art technological sources as well as observations of gouache paintings from a variety of different artists including Hans Bol, Marco Ricci, James Stuart, and Johann Ludwig Aberli. The author’s own experiences with gouache painting will also feed into the portrayal of a technique which in the past has often been disparaged and is underrepresented in the art technological research.
Pain Constructions in modern Arabic dialects: a typological overview
Authors: Manfredi Stefano
Published: November 2022

Pain Constructions (PCs) constitute a class of experiential constructions expressing situations that involve unpleasant physical experiences (e.g.headache,burning eyes, dizziness, etc.). Previous cross-linguistic comparisons have shown that, though languages do not have dedicated morphosyntactic structures for encoding pain, there are certain constructions that are more likely to express physical experiences. Based on original data elicited by means of a situational questionnaire, this paper aims at analyzing the semantic and syntactic properties of PCs in modern Arabic dialects and to make typological generalizations about their cross-dialect variation. Benefiting from insights from both linguistic typology and contact linguistics, the study eventually shows that, despite considerable lexicosemantic and morphosyntactic variation, PCs in Arabic can be reduced to two main syntactic types: locational and inverse constructions.
The typology of negation across varieties of Arabic
Authors: Lucas Christopher , Alluhaybi Mohammed
Published: November 2022

Drawing primarily on the data collated by Alluhaybi (2019.Negation in modern Arabic varieties from a typological point of view. London: SOAS University of London PhD thesis), this article first situates Arabic within the crosslinguistic typology of negative strategies put forward, among others, by Miestamo (2005.Standard negation: The negation of declarative verbal main clauses in a typological perspective. Berlin: Mouton de Gruyter). It then surveys the main parameters of variation among different varieties of Arabic in the expression of standard negation, non-verbal negation, and negative imperatives, with a particular focus on the issue of the single versus bipartite expression of negation. The article finishes by looking at some recent debates concerning the diachronic evolution of the observed patterns.
Subregular linguistics: bridging theoretical linguistics and formal grammar
Authors: Graf Thomas
Published: November 2022

Subregular linguistics is a fairly new approach that seeks a deeper understanding of language by combining the rigor of formal grammar with the empirical sophistication of theoretical linguistics. The approach started in phonology but has since branched out to morphology and even syntax, unearthing unexpected parallels between these three domains of language. In this paper, I argue based on these results that subregular linguistics has a lot to offer to both fields. Subregular linguistics may be the ideal conduit for knowledge transfer between these two communities.
Myopathic dysphagia caused by thyrotoxicosis: a case report and review of the literature
Authors: Alwithenani Raad , Andrade Danielle M , Zhang Lingxin , Gomez-Hernandez Karen E
Published: November 2022

Myopathy caused by thyrotoxicosis is not uncommon. Skeletal muscles are commonly involved, but dysphagia is a rare manifestation of thyrotoxicosis. We aim to raise awareness of dysphagia caused by hyperthyroidism and review similar cases in the literature. We present a case of severe dysphagia caused by hyperthyroidism. We also summarize similar case reports in the literature. Our patient is a 77-year-old man who presented with thyrotoxicosis related to Graves’ disease (GD), dysphagia to both liquid and solid food, and weight loss. Further investigations revealed severe esophageal dysphagia and a high risk for aspiration. He required the placement of a G-tube for feeding. After 8 weeks of methimazole treatment, his thyroid function normalized and his dysphagia improved significantly, leading to the removal of the feeding G-tube. We summarize 19 case reports published in the literature of hyperthyroidism leading to dysphagia. Patients with thyrotoxicosis and dysphagia are at higher risk for aspiration pneumonia and thyroid storm. Based on previous case reports, on average, approximately 3 weeks of treatment with anti-thyroidal drugs and beta-blockers is needed before patients can eat normally. We report a case of dysphagia associated with GD, which is rare and needs prompt recognition to restore euthyroid status. Dysphagia generally resolved with normalization of thyroid function.

Learning points

Myopathy caused by thyrotoxicosis is not uncommon.

Skeletal muscles are commonly involved, but dysphagia is a rare manifestation of thyrotoxicosis.

Dysphagia due to hyperthyroidism resolves with normalization of thyroid function.

Early recognition of dysphagia related to hyperthyroidism and early initiation of therapy may help reverse the dysphagia and prevent complications.

Published: November 2022

Este trabajo tiene por objetivo analizar el lugar que deben tener en el Acceso a la Profesión Docente (APD) dimensiones actitudinales como el compromiso y la ética profesional. Debidamente planteado, creemos que hemos de reflexionar -al menos- sobre tres grandes cuestiones: sentido y fundamentos (a modo de “background” o “rationale”) que conlleva esta cuestión; su lugar -como dimensión destacable- en el Marco de Competencias Docentes; y -en tercer lugar, más ampliamente- formulamos una revisión de la propuesta de APD, que ha defendido la Conferencia de Decanos/as de las Facultades de Educación, de evaluación para la profesión docente de estas dimensiones complejas y dónde debe situarse tal evaluación (si al ingreso en el grado o, como defendemos algunos, a la salida: es decir, durante los años del grado o en el ingreso definitivo en la profesión). Estas dos últimas forman parte justo de las dos primeras propuestas de entre las 24 proposiciones del Ministerio.
Universities and Innovation Potential of the City: A Quasi-Experimental Study of Newly Built Campuses of Colleges and Universities in China
Authors: Ha Wei
Published: November 2022

Colleges and universities have been playing an increasingly important role in regional innovation-driven development. Based on panel data (1999-2016) of 287 cities in China, this study conducted an empirical analysis of the influences of the new campuses which were built for the expanded college enrollment on the city’s patentable inventions and innovations. The Time-varying DID model was adopted in the analysis. The regression results demonstrate that newly built campuses have boosted inventions and innovations in their cities, benefiting various innovators including individuals and firms; that the impact of newly built campuses increases over time; the newly built campuses of vocational colleges have mainly influenced innovation actors like businesses, while those of regular colleges and universities have impacted both individuals and organizations; that the new campus built in the different city from its headquarter exerts greater promoting effects on the innovation of the city than the campus relocated in the original city and the campus of a newly established university; that the indirect effect of newly built campuses on the invention of all innovation actors is more significant than the impact of their direct collaboration with the latter; that a newly built campus have a more prominent effect on regional innovation when it is situated in an area with a high concentration of universities; and that the existence of the old campus of a university amplifies the promoting effect of its newly built campus on local innovation and the amplifying function strengthens over time.

Authors: Yao Jijun
Published: November 2022

In China’s educational community, there is a consensus that any decision-making or advance in reform must be based on scientific evidence. It has been realized that the traditional instruction modalities that draw on educators’ personal experience have become ineffective in accomplishing better education in the new era. In this context, China’s educational administrators have been committed to constructing an evidence-based system to enable reform in education.
¿Contribuye la ganadería bovina de Costa Rica al incremento del metano atmosférico y al calentamiento global?
Authors: Montenegro Ballestero Jhonny
Published: November 2022

[Introduction]: Methane (CH4), like other gases that have been increasing in the atmosphere, are responsible for the greenhouse effect that leads to global warming and climate change. One source of this gas is cattle farming; however, methane has a relatively short half-life in the atmosphere. [Objective]: Consequently, if methane lasts only few years in the atmosphere, what is the contribution to the atmospheric increase of this gas made by the national cattle herd? To answer this question, the present work was carried out. [Methodology]: Firstly, the historical trend of enteric methane emission from the national cattle herd is described, and subsequently the net change of this gas in the atmosphere, product of bovine activity in Costa Rica, is shown. Based on national bovine population statistics, the emission of enteric methane was estimated for the national herd and according to bovine production system, using the methodology of the Intergovernmental Panel on Climate Change. Considering the half-life of methane in the atmosphere, calculations were made to estimate the change in atmospheric methane coming from the Costa Rican cattle herd. [Results]: The results show that the national bovine population reached its maximum at the end of the 1980s; the behavior of enteric methane emission showed the same trend, varying according to the production system. The change in atmospheric methane because of the contribution from the national cattle herd showed to be incremental from 1940 to 1990, subsequently decreasing to remain stable from 2000. [Conclusions]: It is concluded that in the last 30 years the Costa Rican cattle ranch has not contributed to the atmospheric increase of this gas.

Background: Cotton dust exposure increases the risk of developing lung diseases including Byssinosis. The prevalence of byssinosis is more in developing countries compare to developed countries. For the past forty years there are little information known about the prevalence of byssinosis and its associated risk factors among textile workers in Tanzania. Objective: The study aimed to assess dust exposure and associated risk factors among textile workers, in Dar es Salaam, Tanzania. Material and methods: The study design was descriptive cross sectional study conducted from March to August 2019. Stratified sampling technique was used to obtain 325 participants (exposed 164 and control 161) respectively. A modified British Medical Research Council (BMRC) questionnaire and Side Kick Casella Pump were used for data collection. Data were analyzed using Statistical Package for Social Science software 23 versions. Chi square test and Binary logistic regression were performed to check for association. A 95% confidence Interval with a significance expressed in P˂0.05 was used. Results: Prevalence of byssinosis in the exposed group was 18.9% and 6.2% in the control group. Respiratory symptoms such as Coughing more days in three consecutive months (P˂0.001), wheezing (P˂0.02), dyspnoea I (P˂0.03), dyspnoea II (P˂0.007), and dyspnoea III (P˂0.002), were higher among exposed group compare to control group and the differences were statistically significant. The department of weaving had higher dust level of arithmetic mean of 2.20 mg/m3 (SD =0.32). Working experience (P˂0.02), previously respiratory symptoms (P˂0.001), were significant risk factors for byssinosis. Conclusion: In conclusion, our study shows that workers who are exposed cotton dust have higher prevalence of byssinosis and other respiratory symptoms. Awareness of the byssinosis disease, and necessary preventive measure need to be highlighted among stakeholders.

The new analysis of inclusive proton spectra from 3H(α,p)6He reaction was performed. The existence of two new excited levels of 6He with energy parameters E2ex.s.*= 2.4 MeV, Γ = 0.4 MeV; E3ex.s.*= 3.0 MeV, Γ = 0.6 MeV was confirmed as a result of new parameterization performed using energy parameters obtained from the correlation kinematic-incomplete experimental study of 3H(α,pα)nn reactions at Eα = 27.2 MeV and Eα = 67.2 MeV in contrast to the initial analysis, in which the resonance observed above the known first excited 6He level E1ex.s. = 1.8 MeV was treated as the second broad excited level E2ex.s. = 2.98 (0.17) MeV, Γ2ex.s. = 2.39 (0.27) MeV.

Published: November 2022

Analizamos narrativas y prácticas de exguerrillos de las Farc-EP alrededor de iniciativas socioeconómicas durante su reincorporación colectiva en espacios definidos por el acuerdo de paz en el Caribe Colombiano, para conocer reconfiguraciones territoriales en la transición de la guerra a la construcción de paz. Realizamos un estudio etnográfico con 24 exguerrilleros vinculados a iniciativas socioeconómicas desarrolladas después de la dejación de armas. En conclusión, las territorialidades y reterritorializaciones gestadas por exguerrilleros situados en el posacuerdo, evidencian procesos de representación, redistribución y reconocimiento orientados a una paz con justicia social; además, contribuyen a la restauración de relaciones sociales en zonas históricamente abatidas por la guerra, como una muestra pedagógica y política para la región y el país.
changing structure of school to work transition in Brazil

Published: November 2022

This paper provides an in-depth analysis of the changing structure and consequences of the links between the educational system and labor markets in Brazil in the past 30 years. Using the linkages methodology proposed by DiPrete et al. (2017) and Elbers (2021), we identify changes in education-occupation linkage that were offset by Brazil’s rapid educational expansion, distinguishing between changes in rates and changes in the structure of school-to-work linkages. We find that the overall compositional shift towards higher educational levels did not have substantial effects on occupational allocation, yet the trends for younger and older workers, as well as for workers with different fields of study in the tertiary system, were fundamentally different. Our findings suggest that the features of educational expansion in Brazil – i.e., privatization, field of study concentration, and quality discrepancies – contributed to a weakening of the links between education and occupational systems.

The problem in the management of blue swimming crab (BSC) fisheries is a decrease in stock that overlaps with an increase in fishing activities. This study aimed to analyze the ratio of spawning potential (SPR), reproductive potential, and reproductive productivity of BSCs taken from the Spermonde Islands. Spawning potential was analyzed using SPR, while reproductive potential analysis used the relative proportion of data between female, berried female and the average fecundity of each class size. The results showed that the BSC in Spermonde were growth overfishing and recruitment overfishing. The SPR of the BSC was estimated to be 7%, below the biological reference point. The highest reproductive potential index of berried females occurred in the group with a carapace width of 111-120 mm which contributed 36.84% of the total egg production. The value of reproductive productivity was 1.35 indicating a productive population. Current legislation allows the capture of BSCs with carapace sizes larger than 100 mm. Based on the data of this study, this size limit has the potential to eliminate 65.92% of the total egg production in the Spermonde Islands. To ensure the sustainability of BSCs in the Spermonde Islands, it is necessary to limit size by capturing BSCs >120 mm to protect the berried female and increase total egg production.
