Authors: Zhou Lian-ji , Yang Da-wei , Ou Li-Na , Guo Xing-Rong , Wu Biao-liang
Published: August 2020

Background. Long noncoding RNA MALAT1 is closely related to diabetes and kidney diseases and is expected to be a new target for the diagnosis and treatment of diabetic nephropathy. Objective. This study aimed to explore the circulating expression level and significance of lncRNA Malat1 in patients with type 2 diabetes mellitus (T2DM) and diabetic kidney disease (DKD). Methods. Quantitative real-time PCR (qPCR) was conducted to assess the expression of lncRNA Malat1 in 20 T2DM patients, 27 DKD patients, and 14 healthy controls, and then, the clinical significance was analyzed. Results. LncRNA MALAT1 expression in peripheral blood mononuclear cells (PBMC) was significantly upregulated in T2DM and DKD groups when compared to control. Pearson’s correlation analysis showed correlation of lncRNA MALAT1 levels with ACR, urine β2-microglobulin (β2-MG), urine α1-microglobulin (α1-MG), creatinine (Cr), and glycosylated hemoglobin (HbA1c), while negative with superoxide dismutase (SOD) (r=−0.388, P<0.05). Binary regression analysis showed that ACR, creatinine, α1-MG, and LncRNA Malat1 were the risk factors for diabetic nephropathy with OR value of 1.166, 1.031, 1.031, and 2.019 (P<0.05). The area under ROC curve (AUC) of DKD identified by the above indicators was 0.914, 0.643, 0.807, and 0.797, respectively. The AUC of Joint prediction probability of DKD recognition was 0.914, and the sensitivity and specificity of DKD diagnosis were 1.0 and 0.806, respectively. (Take ≥0.251 as the diagnostic cutoff point). Conclusion. LncRNA Malat1 is highly expressed in DKD patients, and the combined detection of ACR, creatinine, α1-MG, and LncRNA Malat1 with diabetes mellitus may be the best way to diagnose diabetic nephropathy.

Published: August 2020

The moisture absorption behavior of flax fiber‐reinforced epoxy composites is deliberated to be a serious issue. This property restricts their usage as outdoor engineering structures. Therefore, this study provides an investigation of moisture in flax fibers on the performance of the flax/epoxy composite materials based on their shear responses. The ±45° aligned flax fibers exposed to different relative humidities (RH) and the vacuum infusion process was used to manufacture the composite specimens. The optimum shear strength (40.25 ± 0.75 MPa) was found for the composites manufactured with 35% RH‐conditioned flax fibers, but the shear modulus was reduced consistently with increasing RH values. Although shear strength was increased because of fiber swelling with increased moisture absorption rate until 35% RH environments with good microstructures, nonetheless, strength and modulus both started to decrease after this range. A very poor microstructure has been affirmed by the SEM images of the composite samples conditioned at 90% RH environments.

Published: August 2020

In this paper, hourly observations of precipitation, wind, and PM2.5 and PM10 concentrations in Qinhuangdao from 2016 to 2018 were used to study the effects of precipitation and wind on PM2.5 and PM10 concentrations. The results show that precipitation has a certain wet scavenging effect on PM2.5 and PM10, and the scavenging effect on PM10 is greater than that on PM2.5. Precipitation above moderate rainfall is concentrated from May to September, and light rain in winter increases the concentration of pollutants. The changes of PM2.5 before and after precipitation are related to the initial concentration of PM2.5 before precipitation, precipitation intensity, and precipitation duration. The scavenging effect of precipitation on PM10 is closely related to the initial concentration of PM10 before precipitation. The higher the initial concentration of PM10 is, the greater the removal amount of precipitation will be. Moderate or above pollution weather mainly occurs in the northeast, southwest, and west wind meteorological conditions; the more westerly the wind, the more the pollution; north wind and northwest wind have the most obvious scavenging effect on PM2.5 and Pm10; when the wind speed increases to 2 m/s, the concentration of PM2.5 and PM10 can be reduced; when the wind speed is more than 4 m/s, the concentration of PM10 increases under the south wind, southeast wind, east wind, and northeast wind.

Published: August 2020

Medicinal plants have been used as a source of effective and safe alternative therapeutic agents for various ailments including inflammation. In fact, the aim of this study is to assess the topical anti‐inflammatory and antioxidative potential effects of Cucurbita pepo (pumpkin), Linum usitatissimum (linseed), and Opuntia ficus indica (prickly pear) oils on acute inflammation using carrageenan‐induced paw edema model. The study was conducted on 36 rats splitted in 6 groups: a normal control group and 5 carrageenan‐treated groups (1%), each treated with either a normal saline, the reference drug (“Inflocine®” 2 mg/paw), pumpkin, linseed, or prickly pear oils (25 μl/paw). The response to these treatments was mainly assessed by the measuring of edema paw size, hematological and biochemical analysis, oxidative stress testing, and histological study. All the studied seed oils especially prickly pear oil proved to be efficient in treating acute inflammation. The oil‐treated groups revealed a significant (p < 0.05) decrease in the clinical signs of inflammation, hematological parameters (white blood cells and platelets), concentrations of CRP and fibrinogen, and congestion compared to the normal saline‐treated group. The results also showed that the tested oils, endowed with a radical scavenging ability, could significantly increase the activities of SOD, CAT, and GPx in carrageenan‐treated skin by reducing the lipid peroxidation and protein oxidation (TBARS, AOPP). The anti‐inflammatory effect of the tested oils was closely related to both their antioxidant properties as well as their bioactive compounds (polyunsaturated fatty acids, vitamin E, and phytosterols). For the first time, the findings of the current study highlight the “in vivo” anti‐inflammatory property of pumpkin, linseed, and prickly pear oils on carrageenan‐induced acute inflammation by regulating inflammatory mediators and oxidative stress markers.

Published: August 2020

Few studies have investigated household interventions to enhance indoor air quality (IAQ) and health outcomes in relatively low-income communities. This study aims to examine the impact of the combined intervention with asthma education and air purifier on IAQ and health outcomes in the US-Mexico border area. An intervention study conducted in McAllen, Texas, between June and November 2019 included 16 households having children with asthma. The particulate matter (PM2.5) levels were monitored in the bedroom, kitchen, and living room to measure the IAQ for 7 days before and after the intervention, respectively. Multiple surveys were applied to evaluate changes in children's health outcomes. The mean PM2.5 levels in each place were significantly improved. Overall, they significantly decreased by 1.91 μg/m3 on average (p<0.05). All surveys showed better health outcomes; particularly, quality of life for children was significantly improved (p<0.05). This pilot study suggests that the combined household intervention might improve IAQ in households and health outcomes for children with asthma and reduce health disparities in low-income communities. Future large-scale studies are needed to verify the effectiveness of this household intervention to improve IAQ and asthma management.

Published: August 2020

The aim of this study was to investigate genetic structures and expression of blaOXA-58 gene in five Acinetobacter baumannii clinical isolates recovered from two hospitals in southern Vietnam during 2012‐2014. A. baumannii isolates were identified by automated microbiology systems and confirmed by PCR. All isolates were characterized as multidrug resistant by antimicrobial testing using the disk diffusion method. Four imipenem susceptible and one nonsusceptible isolates (MIC > 32 μg·ml-1) were identified by E‐test. PCR amplification of blaOXA-58 gene upstream and downstream sequences revealed the presence of ISAba3 at both locations in one multidrug‐resistant isolate. Semiquantitation of blaOXA-51 and blaOXA-58 gene expression was performed by the 2-ΔΔCt method. The blaOXA-51 gene expression of five isolates showed little difference, but the isolate bearing ISAba3‐blaOXA-58‐ISAba3 exhibited significantly higher blaOXA-58 mRNA level. Higher β‐lactamases activity in periplasmic than cytoplasmic fraction was found in most isolates. The isolate overexpressing blaOXA-58 gene possessed very high periplasmic enzyme activity. In conclusion, the A. baumannii isolate bearing ISAba3‐blaOXA-58 gene exhibited high resistance to imipenem, corresponding to an overexpression of blaOXA-58 gene and very high periplasmic β‐lactamase activity.

Published: August 2020

Background. This retrospective study aims at comparing the variation of peripheral inflammatory markers in recurrent and cancerous vocal fold leukoplakia (VFL) and at exploring the potential connection with pathological outcomes. Methods. The patients undergoing carbon dioxide laser surgery with postoperative pathological diagnosis of recurrent vocal fold leukoplakia in the last 5 years were included. The clinical data were collected, and neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocytes-to-lymphocyte ratio (MLR) before and after recurrence and canceration were calculated. Related comparison with two-grade pathological classification was made to evaluate their potential connection with postsurgical histopathology and clinical events. Results. The data of 193 patients were engaged into research, as 111 in the recurrence group (Group A) and 82 in canceration group (Group B). The NLR, PLR, and MLR were significantly increased in canceration event compared to the first (P=0.009,0.004,0.007, respectively) and penultimate (P=0.013,0.041,0.006, respectively) time when the previous pathologies were leukoplakia. When redividing the Group A according to the two-grade pathological classification, the high-risk groups showed statistically higher NLR and PLR values than low-risk groups in the subgroups with grade changing (P=0.016,0.005,0.007,0.005, respectively) and subgroups without grade changing (P=0.020,0.027,0.030,0.029, respectively). Conclusions. NLR, PLR, and MLR are reliable biomarkers in the circulation system which show significantly interrelation with the pathological progression of vocal fold leukoplakia. Presurgical evaluation of NLR, PLR, and MLR may have potential values to indicate the following treatment in clinical practice.

Published: August 2020

The treatment goal for spinal cord injury (SCI) is to repair neurites and suppress cellular apoptosis. This study is to investigate the effects of nuclear heme oxidase‐1 (HO‐1) on the acute spinal cord injury and the related mechanisms. The rat model of the SCI was established. On day 7, before model establishment, the adenovirus vector carrying nuclear HO‐1 (Ad‐GFP‐HO‐1CΔ23) was injected into the animals into the tenth thoracic spine (T10) segment by the intrathecal injection. Starting from after the model establishment to day 28, the recovery of motor function was assessed by the Basso‐Beattie‐Bresnahan (BBB) scoring method. Immunofluorescence was performed to detect the expression patterns of nuclear and cytoplasmic proteins. HE and Nissl staining methods were used to evaluate the structural damage and the number of surviving neurons near the injured area. The TUNEL method was conducted to evaluate the apoptotic degree. Protein expression levels were detected with the Western blot analysis. The BBB assay scores in the nuclear HO‐1 group were significantly higher than the blank and adenovirus control groups. Moreover, compared to the blank and adenovirus control groups, the neuronal apoptosis in the nuclear HO‐1 group was significantly alleviated. Furthermore, the expression levels of the endoplasmic reticulum stress‐related proteins, i.e., CHOP, GRP78, and caspase‐12, were significantly decreased in the nuclear HO‐1 group. Nuclear HO‐1 significantly improves the SCI, promotes the functional recovery, inhibits the endoplasmic reticulum stress, and alleviates the apoptotic process after SCI.

Published: August 2020

In this article, approaches to estimate the number of periodic solutions of ordinary differential equation are considered. Conditions that allow determination of periodic solutions are discussed. We investigated focal values for first-order differential nonautonomous equation by using the method of bifurcation analysis of periodic solutions from a fine focus Z=0. Keeping in focus the second part of Hilbert’s sixteenth problem particularly, we are interested in detecting the maximum number of periodic solution into which a given solution can bifurcate under perturbation of the coefficients. For some classes like C7,7,C8,5,C8,6,C8,7, eight periodic multiplicities have been observed. The new formulas ξ10 and ϰ10 are constructed. We used our new formulas to find the maximum multiplicity for class C9,2. We have succeeded to determine the maximum multiplicity ten for class C9,2 which is the highest known multiplicity among the available literature to date. Another challenge is to check the applicability of the methods discussed which is achieved by presenting some examples. Overall, the results discussed are new, authentic, and novel in its domain of research.

Published: August 2020

The traditional biogas heating system has the disadvantages of a low energy efficiency ratio and high energy consumption. In this study, a solar-untreated sewage source heat pump system (SUSSHPS) was developed for heating a 12 m3 multiphase flow digester (MFD) in Suining, China. To investigate the operating effects, two modes were defined according to the solar fractions in different regions. On the basis of experimental data, thermodynamic calculations and operating simulation analysis were performed, and the solar collector area (Ac) and the minimum length of the sewage double-pipe heat exchanger (lmin) for the two modes were calculated. The results indicated that the Ac and lmin of mode 2 were larger than those of mode 1 at different solar fractions. Additionally, the results suggested that mode 1 can be used at a solar fraction of <0.33, and mode 2 can be used at a solar fraction of >0.5. Moreover, a comprehensive evaluation of different biogas heating systems was performed. Two evaluation methods were used for modeling calculations, and the results of the two methods were consistent. The SUSSHPS had the largest comprehensive evaluation value among the four systems. The proposed SUSSHPS can play a significant role in improving current biogas heating systems and promoting the development of biogas projects.

Authors: Xu Shujiang , Hao Qixian , Ma Bin , Wang Chunpeng , Li Jian
Published: August 2020

Exponential moments (EMs) are important radial orthogonal moments, which have good image description ability and have less information redundancy compared with other orthogonal moments. Therefore, it has been used in various fields of image processing in recent years. However, EMs can only take integer order, which limits their reconstruction and antinoising attack performances. The promotion of fractional-order exponential moments (FrEMs) effectively alleviates the numerical instability problem of EMs; however, the numerical integration errors generated by the traditional calculation methods of FrEMs still affect the accuracy of FrEMs. Therefore, the Gaussian numerical integration (GNI) is used in this paper to propose an accurate calculation method of FrEMs, which effectively alleviates the numerical integration error. Extensive experiments are carried out in this paper to prove that the GNI method can significantly improve the performance of FrEMs in many aspects.

Published: August 2020

The last few years have seen the great potential of artificial intelligence (AI) technology to efficiently and effectively deal with an incredible deluge of data generated by the Internet of Things (IoT) devices. If all the massive data is transferred to the cloud for intelligent processing, it not only brings considerable challenges to the network bandwidth but also cannot meet the needs of AI applications that require fast and real-time response. Therefore, to achieve this requirement, mobile or multiaccess edge computing (MEC) is receiving a substantial amount of interest, and its importance is gradually becoming more prominent. However, with the emerging of edge intelligence, AI also suffers from several tremendous security threats in AI model training, AI model inference, and private data. This paper provides three novel defense strategies to tackle malicious attacks in three aspects. First of all, we introduce a cloud-edge collaborative antiattack scheme to realize a reliable incremental updating of AI by ensuring the data security generated in the training phase. Furthermore, we propose an edge-enhanced defense strategy based on adaptive traceability and punishment mechanism to effectively and radically solve the security problem in the inference stage of the AI model. Finally, we establish a system model based on chaotic encryption with the three-layer architecture of MEC to effectively guarantee the security and privacy of the data during the construction of AI models. The experimental results of these three countermeasures verify the correctness of the conclusion and the feasibility of the methods.
Seismic Fragility Analysis of Bridge Group Pile Foundations considering Fluid-Pile-Soil Interaction
Authors: Zhang Chao , Wu Chengwang , Wang Piguang
Published: August 2020

The cross-sea bridges play an important role to promote the development of regional economy. These bridges located in earthquake-prone areas may be subjected to severe earthquakes during their lifetime. Group pile foundations have been widely used in cross-sea bridges due to their structural efficiency, ease of construction, and low cost. This paper investigates the seismic performance of bridge pile foundation based on the seismic fragility analysis. Based on the analysis platform OpenSees, the three-dimensional finite model of the bridge pile foundation is developed, where the pile-water interaction is replaced by the added mass method, nonlinear p-y, t-z, and q-z elements are used to simulate pile-soil interaction, and the displacement of the surface ground motion due to seismic excitations is applied on all spring supports. The seismic fragility curves of the bridge pile foundation are generated by using the earthquake records recommended by FEMA P695 as input motions. The curvature ductility based fragility curves are obtained using seismic responses for different peak ground accelerations. The effects of pile-water interaction, soil conditions, and different types of ground motions on the bridge pier fragilities are studied and discussed. Seismic fragility of the pier-group pile system shows that Sec C (the bottom section of the pier) is the most vulnerable section in the example fluid-structure-soil interaction (FSSI) system for all four damage LSs. The seismic responses of Sec E (a pile section located at the interface of the soil layer and water layer) are much lower than other sections. The parameter analysis shows that pile-water interaction has slight influence (less than 5%) on the fragility curves of the bridge pier. For the bridge group pile foundations considering the fluid-pile-soil interaction, PNF may induce larger seismic response than far-field (FF) and no-pulse near field (NNF). The bridge pile foundation in stiff soil is most vulnerable to seismic damage than soft condition.
Modeling a Mechanical Molecular Spring Isolator with High-Static-Low-Dynamic-Stiffness Properties
Authors: Li Zhanyong , Chen Qian , Gu Fengshou , Ball Andrew
Published: August 2020

A mechanical molecular spring isolator (MMSI) is proposed for the purpose of isolating the low-frequency vibration of a heavy payload. The MMSI is a passive vibration isolation technique mimicking molecular spring isolator characteristics of high-static-low-dynamic stiffness (HSLDS). An MMSI consists of a piston-cylinder container filled with the liquid and some hydraulic spring accumulators. The piston would support a lump of mass and be subjected to a specific external vibration excitation force. Those accumulators can get intercommunication by the liquid to produce the transformation from high static stiffness to low dynamic stiffness. The stiffness model of the MMSI with several identical accumulators is established based on the hydrostatic law. After that, some parameters that significantly influence the stiffness characteristics are studied. Results show that the stiffness property of this kind of MMSI demonstrates a piecewise linearity of three segments. It applies the averaging method to acquire amplitude-frequency and phase-frequency relationships of the piecewise linear vibration isolation system. An inevitable jump phenomenon may occur when the exciting force reaches the critical value. The vibration isolation performance is evaluated by energy transmissibility. Finally, an experimental prototype was designed to carry out quasi-static and dynamic experiments to verify the stiffness model and the dynamic properties as an HSLDS vibration isolator.

The Internet has revolutionized the patterns of financial development and economic growth. To assess the impacts of internet penetration on the financial industry, this paper analyzed ten-year Chinese provincial panel data and concluded that regional Internet penetration accelerates financial development. Furthermore, the efficiency of Internet investment in underdeveloped provinces is better than that in developed provinces. More meaningfully, Internet penetration promotes the transparency of the securities market and regional financial participation. This indicates that Internet technology facilitates the advancement of the finance industry and the securities market.
One Bullet Causing Five Holes, Laparoscopic Exploration with Repair: A Case Report and Review of the Literature
Authors: Jones Hunter , Ahmed Hassan
Published: August 2020

Introduction. The proper treatment of penetrating abdominal wounds has been a controversial topic, and the preferred regimen has evolved over time. In recent years, many trauma centers have started using diagnostic laparoscopy in stable trauma patients in an effort to reduce the incidence of nontherapeutic laparotomy. This is more commonly seen in solid organ injuries, and its role is less clearly defined for hollow visceral injuries. Case Presentation. A 19-year-old male presented with a gunshot wound (GSW) to the abdomen with mild peritoneal signs and computed tomography (CT) findings. Diagnostic laparoscopy was performed with the repair of five lacerations to intra-abdominal organs including the sigmoid colon, rectum, bladder, and small bowel. Discussion. To our knowledge, this is the first case report in the literature detailing such a GSW repair. Abdominal GSWs have been repaired laparoscopically in the past, but none have elaborated on the repair of multiple defects of bowel and/or bladder. Conclusion. Therapeutic laparoscopy can be considered in selected cases of penetrating abdominal trauma. Laparoscopy offers several advantages over laparotomy including decreased mortality, complication rate, and length of stay.
A Simultaneous Safety Analysis of Crash Frequency and Severity for Highway-Rail Grade Crossings: The Competing Risks Method
Authors: Keramati Amin , Lu Pan , Zhou Xiaoyi , Tolliver Denver
Published: August 2020

This paper proposes a mathematical model, the competing risks method, to investigate highway-rail grade crossing (HRGC) crash frequency and crash severity simultaneously over a 30-year period. The proposed competing risks model is a special type of survival analysis to accommodate the competing nature of multiple outcomes from the same event of interest; in this case, the competing multiple outcomes are crash severities, while event of interest is crash occurrence. Knowledge-gain-based benefits to be discovered through the application of this model and 30-year dataset are as follows: (1) a straightforward and integrated one-step estimation process that considers both crash frequency and severity likelihood in the same model, so direct hazard ranking considering both crash frequency and severity likelihood is possible; (2) interpretative effects of identified covariates from both the direction and magnitude perspectives; and (3) the long-term cumulative effect of contributors with the cumulative incidence function.

Published: August 2020

Addisonian crisis is the life-threatening acute manifestation of adrenal insufficiency due to absolute or relative glucocorticoid deficiency. Adrenal haemorrhage is a rare condition of unknown incidence with the risk of adrenal insufficiency and death, not uncommonly first being diagnosed on the pathologists table. We report the case of a 68-year-old female patient with respiratory tract infection suffering acute life-threatening adrenal insufficiency caused by bilateral adrenal haemorrhages following orthopedic surgery while taking anticoagulation therapy. The patient rapidly deteriorated with hypotension, showing how important it is to consider a possible Addisonian crisis when this scenario occurs, especially with precipitating factors such as anticoagulant therapy, sepsis, or surgery.

Published: August 2020

Urachal remnant anomalies are uncommon in adults and can be confused with a variety of clinical conditions when symptomatic or infected. Vesicourachal diverticulum is the rarest type, accounting for approximately 3% to 5% of congenital urachal anomalies. We report the case of a 42-year-old female patient, who presented to the emergency department with lower abdominal pain and a palpable abdominal mass. An infected vesicourachal diverticulum was diagnosed after imaging studies and was initially treated with intravenous antibiotic therapy and drainage of the urachal diverticulum to the urinary bladder through a JJ stent. Finally, the patient underwent open surgical excision of the urachal remnant. The postoperative course was uneventful, and the histopathological examination confirmed the diagnosis of vesicourachal diverticulum. We recommend drainage of an infected vesicourachal diverticulum through the bladder by JJ stent placement inside its lumen during cystoscopy, as an alternative to percutaneous drainage reported in the literature.

Published: August 2020

Purpose. To assess the agreement between the qualitative clinical method and the quantitative photographic method of evaluating normal and abnormal ocular versions in patients with inactive Graves’ orbitopathy (GO). Methods. Forty-two patients with inactive GO had their ocular versions evaluated clinically according to three categories: normal, moderate alterations (−1 or −2 hypofunction), and severe alterations (−3 or −4 hypofunction). The subjects were photographed in the 9 positions of gaze, and the extent (mm) of eye movement in each position was estimated using Photoshop® and ImageJ and converted into degrees with a well-established method. The agreement between the two methods (qualitative vs. quantitative) for classifying ocular versions as normal or abnormal was assessed. Results. The mean quantitative measurements of versions were significantly different for each clinical category (normal, moderate alterations, and severe alterations) in the following five positions: abduction, adduction, elevation in abduction, elevation, and elevation in adduction (p<0.001). No such pattern was observed for the three infraversion positions (depression in abduction, p=0.573; depression, p=0.468; depression in adduction, p=0.268). Conclusion. The agreement was strong between the quantitative photographic method and the qualitative clinical method of classifying ocular versions, especially in lateral and supraversions, which are typically affected in GO. Digital photography is recommended for the assessment of ocular versions due to its practicality, suitability for telemedicine applications, and ease of monitoring during follow-up. This trial is registered with NCT03278964.

O uso de ferramentas digitais na preservação da arte escultórica tumular
Authors: Oliveira Fabiana Lopes de , Santos Reinaldo Luiz
Published: August 2020

Cemitérios são espaços onde é possível identificar elementos culturais de uma sociedade, que se expressam pela arquitetura do túmulo e do paisagismo. Porém o distanciamento das pessoas destes locais os torna propícios para a ação dos vândalos. Logo, as necrópoles precisam ser incluídas em roteiros culturais nas cidades, além de serem instituídos programas de manutenção periódica e segurança nos túmulos, capelas e mausoléus. O objetivo deste estudo é apresentar duas formas de preservação do patrimônio cultural: a primeira consiste na identificação das principais manifestações patológicas que danificam as esculturas, com a confecção dos mapas de danos; e a segunda, no levantamento das características físicas das peças, de modo a documentar suas formas, cores, texturas e volumetria. Para ambas as propostas, utilizaram-se duas ferramentas digitais atuais: a fotogrametria e o escaneamento a laser. As obras estudadas são: Pietá (1929), do escultor Galileo Emendabili, localizada no Cemitério da Consolação em São Paulo e Último adeus (1945), de Alfredo Oliani, no Cemitério São Paulo, utilizando-se os softwares ReCap Photo, da Autodesk, e Trimble RealWorks, da empresa Trimble, para obtenção dos modelos tridimensionais das obras escultóricas. Constatou-se que para a utilização destas tecnologias é necessário planejamento prévio para o levantamentodos dados, principalmente devido às interferências climáticas e de localização das obras. As ferramentas utilizadas foram eficientes quanto à caracterização formal das obras e podem ser utilizadas para a preservação conceitual e material da peça.

Muitos dos aspectos que envolvem a redação de textos científicos ficam subentendidos, de modo que pesquisadores iniciantes enfrentam dificuldades em compreender as expectativas que cercam a produção de tais textos. Na busca por equilibrar originalidade e conformidade, o atendimento às regras formais é facilitado pela sua normatização, enquanto outros aspectos relacionados à conformidade não o são. Assim, este ensaio busca contribuir com o esclarecimento do papel da seção de estudos anteriores na construção de um argumento científico. O texto também apresenta uma sugestão de estrutura para a seção de estudos anteriores baseada nas melhores práticas observadas na literatura, e uma estratégia de redação para a consecução de tal estrutura.
Futebol, povo e poder
Authors: Rosa Bruno Navarini , Marques José Carlos
Published: August 2020

Este estudo analisa os documentários Garrincha, alegria do povo (1963), de Joaquim Pedro de Andrade, e Isto é Pelé (1974), de Eduardo Escorel e Luiz Carlos Barreto, com intuito de identificar, tanto no contexto histórico quanto na estrutura das obras, questões que façam referência à relação entre futebol, povo e poder. Os elementos identificados na análise apontaram marcas características da época de produção dos filmes, cujas mensagens transmitidas ao público resultaram, apesar da abordagem sobre dois ídolos do mesmo esporte, em visões opostas no que diz respeito a apoio e resistência aos governos do período.
Joaquim, Vazante e O nó do diabo
Authors: Nascimento Genio de Paulo Alves , Eduardo André De Paula
Published: August 2020

O cinema brasileiro recente tem se atentado ao tema do trabalho escravo, ou, ainda, ao trabalho precarizado e do passado escravocrata do país, há algum tempo, tendência que possivelmente se acentuou após os eventos políticos de 2016, notadamente o impeachment de Dilma Rousseff. O objetivo deste artigo é, através da análise de Vazante, de Daniela Thomas (2017), Joaquim, de Marcelo Gomes (2017) e O nó do diabo (projeto coletivo com direção de Ian Abé, Gabriel Martins, Ramon Porto Mota e Jhésus Tribuzi, em 2018), buscar a compreensão dos fatos políticos recentes, bem as possíveis razões da reiteração do assunto da escravidão e sua relação com o contexto político brasileiro atual.
O acontecimento João de Deus e os enquadramentos na mídia televisiva
Authors: Silva Marcos Vinicius Meigre e
Published: August 2020

Este artigo analisa a construção de sentidos, o acionamento de valores sociais e os posicionamentos assumidos pelos sujeitos em torno do caso de denúncias contra o médium João de Deus. Tomando por objeto empírico o programa Fantástico, da TV Globo, analiso três edições a fim de captar as fases do acontecimento e suas reverberações na televisão. A partir das análises, foi possível apreender tensionamentos em torno dos papéis sociais “pai”, “médium” e “criminoso”, bem como os valores evocados para cada um destes elementos. Por fim, o acontecimento já em fase de normalização se consagra numa espécie de compensação simbólica com a manutenção da prisão do médium.
Política, poder e comunicação em Debord e Arendt
Authors: Coelho Claudio Novaes Pinto
Published: August 2020

Guy Debord é reconhecido como o principal teórico da sociedade do espetáculo, além de ter sido também um importante militante político e agitador cultural. O artigo aqui apresentado, fruto de uma pesquisa de Pós-Doutorado, procura compreender os conceitos de poder deste autor e como eles estão relacionados com o seu projeto de transformação revolucionária da sociedade capitalista. Tendo em vista este objetivo, será realizada uma análise comparativa com o pensamento de Hannah Arendt, reconhecida como uma das mais significativas autoras do século XX e que também desenvolveu reflexões sobre temas presentes nos textos e na atuação de política e cultural de Debord.

Essa pesquisa pretende iniciar um debate acerca do uso da técnica storytelling para podcasts que se enquadram na categoria de radiojornalismo narrativo. Recorremos à revisão bibliográfica para refletir sobre o uso de tal estratégia na composição de narrativas e aplicamos a análise de conteúdo no primeiro episódio da quarta temporada do Projeto Humanos, “O Caso Evandro”, para aprofundar as discussões. Como principal resultado, observamos que, com base nas características do rádio e da mídia sonora, há um terreno propulsor para o desenvolvimento do storytelling.
Classificação morfológica na escala de detalhe no Pontal do Paranapanema, SP
Authors: Cardoso Anna Carolina Dos Santos , Nepomuceno Pablo Luíz Maia
Published: August 2020

O presente artigo visa apresentar a viabilidade da classificação morfológica em escala de detalhe do relevo em bacias hidrográficas, de acordo com as legendas propostas por Colangelo (1996), correspondendo às Unidades Elementares do Relevo; e do quinto táxon da taxonomia proposta por Ross (1992), referente aos tipos e formas de vertentes com o uso de técnicas de geoprocessamento. Para tanto foi tomado como estudo de caso duas sub-bacias hidrográficas do Rio Santo Anastácio, localizadas na região do Pontal do Paranapanema. Os compartimentos morfológicos foram classificados através do processamento de Modelos Digitais de Elevação - MDE e ortofotos em ambiente de Sistemas de Informações Geográficas – SIG. Estes dados foram disponibilizados pela Emplasa (2011), e são provenientes do projeto “Mapeia São Paulo”, último levantamento sistemático de dados topográficos e aerofotogramétricos realizados para todo o território do estado de São Paulo. Como resultado foram obtidas as nove classes possíveis de Unidades Elementares do Relevo e, ao menos, seis classes diferentes de tipos e formas de vertentes, confirmando, portanto, a viabilidade técnica e metodológica dos procedimentos adotados no que se refere ao tratamento dos dados utilizados para a realização da classificação morfológica na escala de detalhe em bacias hidrográficas da região do Pontal do Paranapanema.

Com objetivo de minimizar as intervenções humanas no ecossistema de restinga, foi instituído, em 29 de abril de 1998, o Parque Nacional (PARNA) da Restinga de Jurubatiba, localizado na faixa costeira de parte dos municípios de Macaé e Quissamã e em toda a faixa costeira do município de Carapebus, no Estado do Rio de Janeiro. Neste cenário, o estudo da paisagem fundamentado na abordagem sistêmica e geoecológica mostra-se um importante instrumento de análise, e embasa estudos de ordenamento territorial e planejamento ambiental. O presente estudo teve como objetivo delimitar e caracterizar Unidades Geoambientais do PARNA da Restinga de Jurubatiba e sua zona de amortecimento terrestre. As etapas de desenvolvimento consideraram a base de dados físicos e antrópicos, formada pelos componentes Formações Geológicas, Compartimentos Geomorfológicos, Classes de Solo, Precipitação e Cobertura da Terra e Uso. Correlacionados, resultaram na delimitação das seguintes Unidades Geoambientais: Colinas altas, Colinas altas dissecadas, Colinas baixas, Colinas baixas dissecadas, Planície lacustre, Planície fluviolacustre, Planície marinha, Planície fluviomarinha, Complexo de lagoas paralelas à costa, Área de inundação e Praia. Ainda como forma de caracterizar a paisagem, foram definidas as funções geoecológicas das Unidades Geoambientais em áreas emissoras, transmissoras e receptoras de matéria e energia. Ao considerar o funcionamento sistêmico, a abordagem de análise geoecológica empregada resultou na delimitação de Unidades Geoambientais que refletem a evolução da paisagem, e o Mapa de Unidades Geoambientais pode ser aplicado na gestão territorial da Unidade de Conservação.
Definições e aplicações da resiliência na ciência geográfica
Authors: Oliveira Livania Norberta , Aquino Cláudia Maria Sabóia de
Published: August 2020

O discurso da resiliência tem aumentado na atualidade quer na esfera acadêmica, política e/ou ambiental. Na ciência geográfica tem sido aplicada tanto no âmbito da Geografia Física como da Geografia Humana. Objetiva-se neste estudo demonstrar como o discurso e a definição da resiliência tem sido aplicado no âmbito da ciência Geográfica, com o propósito de contribuir para pesquisas futuras tanto na Geografia como em áreas a fins. Utilizou-se de pesquisa bibliográfica em website de periódicos internacionais e nacionais para identificar as publicações que aplicaram o conceito da resiliência dentro do contexto da Geografia. Constatou-se que a resiliência no campo da Geografia teve maior índice de publicações a partir de 2010, sobretudo no idioma português, embora existam maior número de publicações da temática em inglês, principalmente no campo da Geografia Humana. Verificou-se ainda, que na Geografia Humana a resiliência é mais debatida no âmbito do espaço rural e urbano, já na Geografia Física a resiliência está associada ao conceito de sustentabilidade, vulnerabilidade e capacidade de suporte de um ecossistema, sendo relevante sua aplicação para a gestão e planejamento ambiental.

A previsão de escorregamentos é bastante relevante para o planejamento territorial, na medida que indica os locais com maior probabilidade de serem atingidos por estes processos. Dessa forma, o objetivo deste trabalho é avaliar a suscetibilidade a escorregamentos no litoral norte de Maceió, Nordeste do Brasil, por meio do modelo AHP (Analytic Hierarchy Process) em ambiente SIG (Sistemas de Informação Geográfica). Na hierarquização do modelo foram utilizados parâmetros relativos à geologia, à geomorfologia, aos solos, à declividade e à forma da encosta. A análise espacial foi realizada por meio de métodos multicritérios e álgebra de mapas com a ponderação das variáveis via AHP. Para a validação dos resultados, foi utilizado um mapa de inventário com 29 cicatrizes de escorregamentos mapeadas do ano de 2017. Os resultados mostraram que o mapa de suscetibilidade apresentou um predomínio da classe de suscetibilidade média, ou seja, com médio potencial para ocorrência de escorregamentos. Nesse sentido, as classes de suscetibilidade baixa, média e alta, apresentaram, respectivamente, uma frequência de 26%, 64% e 10%. Ao validar os resultados, 69% das cicatrizes de escorregamentos concentraram-se na classe de suscetibilidade alta; 30% na classe de suscetibilidade média e, apenas, 1% na classe de suscetibilidade baixa, indicando sucesso na previsão realizada. Os mapeamentos indicaram que os locais mais suscetíveis a escorregamentos se situam nas áreas de encostas, principalmente quando correlacionadas com a forte influência da declividade e dos padrões côncavos do terreno.
