DEVELOPMENT AND PERFORMANCE ANALYSIS OF Ni–15Cr2O3–5TiO2 AND Ni–15Al2O3–5TiO2 HVOF COATINGS IN EROSIVE FLY ASH SLURRY
Authors: SINGH AMANPREET , KUMAR HEMANT , KUMAR SATISH
Published: November 2022

This study is focused on improving the mechanical properties and slurry erosion resistance of traditional Ni–20Al2O3 and Ni–20Cr2O3 thermal spray coatings by reducing the 5% of Al2O3 and Cr2O3, respectively, and addition of 5% TiO2 feedstock in both coatings. Thermal sprayed powders were thermally sprayed on SS-420 substrates with high-velocity oxy-fuel (HVOF) method. A lab-scale pot tester was used to conduct the wear testing at low rotating speeds of 750, 1000, 1250, and 1500 rpm. To create severe accelerated conditions, a high mass flux (35–50 wt.%) of fly ash particles was used. Multi-sized fly ash slurries ranging from [Formula: see text][Formula: see text][Formula: see text]m to 250[Formula: see text][Formula: see text]m were used during the experiments to evaluate the impact of particle size fraction on the erosion over a 30–120 min time-period. Coatings’ surface characterization was done to examine more about their composition. According to the findings, the addition of 5% TiO2 powder to both Ni–15%Al2O3 and Ni–15%Cr2O3 coatings significantly improved their wear resistance of SS-420. This occurred because of the enhancement of hardness as well as brittleness by 5% TiO2 in matrix of Ni–15%Cr2O3 and Ni–15%Al2O3 coatings. Moreover, TiO2 particles aid in strengthening of Cr2O3 and Al2O3 reinforcements and the binding with matrix. Also, the results showed that Ni–15Cr2O3–5TiO2 coating showed superior wear resistance compared to Ni–15Al2O3–5TiO2 coating.

The Impacts of Multiscale Urban Road Network Centrality on Taxi Travel: A Case Study in Shenzhen
Authors: Wang Dan , Gong Yongxi , Zhang Xin , Lin Yaoyu
Published: November 2022

As a crucial part of the urban system, road networks play a key role in the evolution of the urban structure. Therefore, studying the structural characteristics of urban road networks is pivotal for improving the efficiency of traffic network nodes and for relieving traffic pressure. This paper applies an urban road network analysis method to measure the centrality of the multiscale road network in Shenzhen, China. Taxi GPS data from October 17 to October 23, 2017, were selected for analysis of spatial distribution characteristics. This paper also established a regression model of taxi pick‐up and drop‐off frequency and road network centrality for further analysis. Several interesting observations were made. With respect to the increasing search radius, the closeness centrality indicator shifts from a multicentered distribution to a single‐centered distribution, while the betweenness centrality indicator shifts from a patchy distribution to a distribution along the main roads. In addition, the straightness centrality indicator turns from a dispersed distribution to a point‐axis distribution, concentrated in the southern part of the city. Second, there were variations between the centrality of the road network and the location of taxi pick‐up and drop‐off points. The regression model gets the highest value of R2, indicating a significant correlation in cases where the search radius is 3 km. Finally, the relationship exhibits a clear positive correlation between the betweenness centrality and taxi pick‐up and drop‐off points. On the other hand, closeness centrality is not correlated with these points. The straightness centrality has a negative correlation with the frequency of taxi pick‐up and drop‐off at 3 km and 8 km scale.

Background. The results of previous clinical trials evaluating the efficacy and safety of recombinant human interleukin-2 (rhuIL-2) for adult patients with pulmonary tuberculosis showed inconsistent results. Accordingly, a comprehensive systematic review and meta-analysis was performed. Methods. Relevant randomized controlled trials (RCTs) were retrieved by searching the PubMed, Embase, Cochrane’s Library, Web of Science, Wanfang, and CNKI databases. A random-effects model was used to combine the results. Results. 18 RCTs with 2630 patients were included in this meta-analysis. Pooled results showed that adjunctive rhuIL-2 significantly increased the odds of sputum culture conversion to negative (risk ratio [RR]: 1.27, 95% CI: 1.09 to 1.47,

Amp-CKlebsiella-Induced Chorioamnionitis and Associated Abnormalities in Cardiotocography: A Case Report with a Narrative Review
Authors: Athar Sufia , Vellamgot Anvar P. , Alansari Lolwa Mohammed
Published: November 2022

Introduction. Infections caused by multidrug-resistant organisms are on the rise in obstetric patients. Chorioamnionitis is associated with adverse pregnancy outcomes. If caused by multidrug-resistant organisms, chorioamnionitis is associated with high maternal and fetal morbidity. Due to the paucity of the literature and the challenges associated with their diagnosis, the diagnosis is usually delayed. This often leads to delays in management, and hence, adverse maternal and neonatal outcomes are noted. Important Clinical Findings. The patient presented with prelabour rupture of membranes for three days. She developed chorioamnionitis in labour, which was refractory to broad spectrum antibiotics. Persistent tachycardia with variable decelerations followed by prolonged fetal deceleration was observed in cardiotocography. Delivery of baby was done by cesarean section in the view of pathological findings in cardiotocography. The primary diagnoses, interventions, and outcomes. Based on the placental culture results, Amp-C Klebsiella-induced chorioamnionitis was diagnosed. Ertapenem was commenced after the sensitivity results. Good feto-maternal outcomes were observed. The neonate was admitted to the neonatal intensive care unit and discharged home in stable condition. Conclusions. Cases of multidrug-resistant organisms-induced chorioamnionitis are rarely reported, though they are associated with maternal morbidity and poor neonatal outcome. In cases of chorioamnionitis, caution should be taken in cases that are refractory to broad-spectrum antibiotics, and multidrug-resistant organisms should be suspected and managed to improve pregnancy outcome.

Published: November 2022

Aim. Qingfei Gujin Decoction (QGD) has been shown to be effective against osteosarcoma. This research was aimed at investigating the main active ingredients and potential mechanisms of QGD acting on osteosarcoma through network pharmacology and molecular docking techniques. Methods. The active ingredients and targets of QGD were screened from the TCMSP database, and the predicted targets were obtained from the PharmMapper database. Meanwhile, the targets of osteosarcoma were collected using OMIM, PharmGKB, and DisGeNET databases. Then, GO and KEGG enrichment analyses were performed by RStudio. PPI and drug-ingredient-target networks were constructed using Cytoscape 3.2.1 to screen the major active ingredients, key networks, and targets. Finally, molecular docking of key genes and their regulatory active ingredients was performed using AutoDockTools 1.5.6 software. Results. 38 active ingredients were collected, generating 89 cross-targets; quercetin, luteolin, β-sitosterol, and kaempferol were the main active ingredients of QGD acting on osteosarcoma, and major signaling pathways such as PI3K-Akt signaling pathway, MAPK signaling pathway, and IL-17 signaling pathway were observed. TP53, SRC, and ESR1 were identified as key proteins that docked well with their regulated compounds. Conclusion. QGD is effective against osteosarcoma through multicomponent, multitarget, and multipathway. This study was helpful for finding effective targets and compounds for osteosarcoma treatment.
Research on Classification Method of Medical Ultrasound Image Processing Based on Neural Network
Authors: Gu Fen , Deng Mei , Chen Xi , An Li , Zhao Zhen
Published: November 2022

In clinical applications, the classification of ultrasound images needs to be processed as an aid to diagnosis. Based on this, a hybrid model of cascaded deep convolutional neural network consisting of two different CNNs and a new classification method are designed and evaluated for its feasibility and effectiveness in ultrasound image classification. A total of 1000 pathological slides of patients with thyroid nodular lesions kept in the Department of Pathology of the First Affiliated Hospital of Lanzhou University, China, were retrospectively collected. After image acquisition, the images were randomly divided into training set, validation set, and test set in the ratio of 4 : 3 : 3. Three convolutional neural network models (VGG 19 model, Inception V3 model, and DenseNet 161 model) with pretraining parameters acquired on the training set were trained, and the models were combined to construct an integrated learning model, and the performance of the models in recognizing pathological images was evaluated based on the test set data. The experimental results show that the VGG 19 model is less effective in classification, with a correct rate of 88.20%, which is lower than that of Inception V3 and DenseNet161 models (92.87% and 92.95%). InceptionV3 and DenseNet161 models have significant advantages in terms of accuracy, number of parameters, and training efficiency, where the DenseNet161 model has faster convergence and better generalization performance, but occupies more video memory in the operation; moreover, the DenseNet161 operation time (1986.48 s) and response time (16 s) are better than the other two models. In addition, the integrated learning of InceptionV3 and DenseNet161 can improve the recognition of pathological images by a single model. Compared with other methods, the performance of the cascaded CNNs proposed in this study is significantly improved, and the multiview strategy can improve the performance of cascaded CNNs. The experimental results demonstrate the potential clinical application of cascaded CNNs, which can provide physicians with an objective second opinion and reduce their heavy workload, in addition to making the diagnosis of thyroid nodules easy and reproducible for people without medical expertise.

Piezo-Phototronic Enhancement of Vertical Structure Photodetectors Based on 2D CsPbBr3 Nanosheets
Authors: Wei Yaocheng , Zheng Xuejun , Chu Liang , Dong Hui
Published: November 2022

Two-dimensional (2D) CsPbBr3 have received great interest in flexible photoelectric devices due to their excellent carrier mobility and tunable optical bandgap. However, it is unknown if the piezo-phototronic effects of a vertically structured 2D CsPbBr3 photodetector
affect its photoelectric performance. Herein, we fabricated a vertical structure device based on 2D CsPbBr3 by using conductive atomic force microscopy and then probed its photoelectric performances under different forces. The photocurrent and on/off ratio under 450 nm laser illumination
rise by up to 2.1 and 5.3 times, respectively, when the applied force is 30 nN as compared with that under 10 nN. To investigate the mechanism underlying the enhancement of photoelectric performance, piezoelectric force microscopy measurement and density functional theory calculation were
used to estimate the vertical piezoelectric coefficient of 2D CsPbBr3, which were found to be 7.3 pm/V and 3.8 pm/V, respectively. The enhancement of performances can be attributed to the piezo-phototronic effect of 2D CsPbBr3, which increases the separation of photogenerated
holes at the interface. These findings propose a comprehensive strategy for enhancing photoelectric performance through piezo-phototronic effects in piezoelectric-based photoelectric devices with vertical structures.

Published: November 2022

This work aims to investigate the structural, electrical, and optical properties of InAs quantum dots (QDs) grown by Molecular Beam Epitaxy on GaAs substrates. As-made samples were thoroughly characterized using different techniques, including Atomic Force Microscopy (AFM), X-ray diffraction
(XRD), and highresolution X-ray diffraction (HRXRD). The patterns of HRXRD revealed an excellent crystallinity of the nanostructure with a maximum diameter of 25 nm as demonstrated by AFM images. The photoluminescence (PL) spectra showed two distinct bands centered at 835 and 1210 nm, and
the intensity of these wavelengths increased with decreasing temperature. A redshift accompanied by a decrease in the FWHM as a function of temperature was observed as a consequence of the thermal escape of carriers. The Ideality factor (n), built-in potential energy, and series resistance
at different temperatures were also determined from current-voltage characteristics curves.

Published: November 2022

Background

Despite the commendable progress made globally in tobacco control, the world is falling short of achieving a 30% relative reduction in current tobacco use by 2025. The African region remains the least in the efforts in fighting the tobacco epidemic and is most exploited by the tobacco industry. Schools have been continuously used for over three decades as a setting for delivering youth smoking prevention programmes; however, the evidence of the effectiveness of those school-based interventions provides varying outcomes. Also, interventions that proved to be effective, in high-income countries (HICs), may not necessarily be effective in the African region as a result of cultural differences and other contrasting factors.

An existing systematic review that explored school-based tobacco prevention programmes among the youth in African countries from 2000 to 2016 showed partial effectiveness. This review will address the gap by updating the 2016 review to examine studies in LMICs to generate findings to help target resources which have the potential to save lives by preventing smoking initiation among young people.

Methods

The JBI methodology for systematic reviews of effectiveness will guide the conduct of this review. A comprehensive strategic search will be developed to retrieve both published and unpublished studies that evaluate school-based interventions to prevent tobacco smoking initiation among in-school young people in LMICs compared to non-intervention programmes. Published studies would be from databases such as MEDLINE via Ovid, CINAHL via EBSCO, Embase, PsycINFO, PsycEXTRA, and the Cochrane Central Register of Controlled Trials. Sources of grey literature would be ProQuest Dissertations and Theses, MedNar, EBSCO Open Dissertations, Open Access Theses and Dissertations, and Trove.

The databases will be searched for published studies in the English language. The processes of study selection, critical appraisal, data extraction, and data synthesis will be in accordance with the JBI approach for reviews of effectiveness with a minimum of two reviewers at each stage. The primary outcome of the review will be the non-initiation of tobacco smoking by the youth.

Discussion

The review will provide synthesized evidence on the effectiveness of school-based smoking initiation prevention among young people in LMICs. The findings of the review would support policymakers and programme implementers to develop targeted interventions for effective tobacco control initiatives.

(Extra) short film study: an emerging narrative practice within global community
Authors: Laskari Iro
Published: November 2022

This article documents a research on the emerging phenomenon of (extra) short film production, that transcends the limits of national characteristics, while having a worldwide distribution, in mostly young audiences. Social media have brought in the frame of audiovisual narratives, through the use of filmic language, a popular practice of storytelling. All kinds of genre are allowed, with a time constraint of a few minutes, not to say seconds. These genres not only have their own audiences, but also gain new ones, due to the way the extra short films are being projected, in a non-linear and often random sequence. In this new “filmic” landscape, the notion of copyright takes a whole new meaning: copy becomes a kind of recognition and homage to the original director, who in turn, becomes instantly famous among thousands of followers. Are these (extra) short films capable of forming a sur-genre themselves? In the context of social media, is video production becoming a new form of folk art?

Ze wzrostem liczby diagnoz zaburzeń psychicznych łączy się wzrost zapotrzebowania na leki psychotropowe, których częstym działaniem niepożądanym jest kserostomia, definiowana jako uczucie suchości w jamie ustnej i prowadząca m.in. do próchnicy i stanów zapalnych błon śluzowych. Największą zdolnością do wywoływania tych działań niepożądanych cechują się leki przeciwpsychotyczne i trójcykliczne leki przeciwdepresyjne, ale nie są od nich wolne także SSRI, antydepresanty atypowe                   i anksjolityki takie jak benzodiazepiny. W leczeniu kserostomii ważna jest profilaktyka kandydozy i próchnicy: odpowiednia dieta, prawidłowe zabiegi higienizacyjne oraz regularne kontrole stomatologiczne. Inne metody to farmakoterapia i stosowanie substytutów śliny. Istnieje korelacja pomiędzy zaburzeniami psychicznymi a wyższą liczbą ubytków próchnicowych, niższą jakością higieny jamy ustnej i większą częstością występowania chorób periodontologicznych.
Cardiovascular reflexes relevant to veterinary anaesthesia
Authors: Marchese Giorgia Anna , Madruga Filipe Lalanda
Published: November 2022

Cardiovascular reflexes can be defined as fast-acting, centrally-mediated feedback mechanisms between the cardiovascular system and the central nervous system. These reflexes help to maintain blood pressure within physiological limits by adjusting heart rate, cardiac contractility and systemic vascular resistance. Several cardiovascular reflexes have been identified in mammals, including the baroreceptor, the chemoreceptor, the Bainbridge and the Bezold-Jarisch reflexes. Under general anaesthesia, several factors can trigger or attenuate cardiovascular reflexes; therefore, it is important to understand their pathophysiological mechanisms. This article reviews the physiology of four of the main cardiovascular reflexes, focusing on their relevance to veterinary anaesthesia.
Measurement of airborne particle emission during surgical and percutaneous dilatational tracheostomy COVID-19 adapted procedures in a swine model: Experimental report and review of literature
Authors: Favier Valentin , Lescroart Mickael , Pequignot Benjamin , Grimmer Léonie , Florentin Arnaud , Gallet Patrice
Published: November 2022

Introduction

Surgical tracheostomy (ST) and Percutaneous dilatational tracheostomy (PDT) are classified as high-risk aerosol-generating procedures and might lead to healthcare workers (HCW) infection. Albeit the COVID-19 strain slightly released since the vaccination era, preventing HCW from infection remains a major economical and medical concern. To date, there is no study monitoring particle emissions during ST and PDT in a clinical setting. The aim of this study was to monitor particle emissions during ST and PDT in a swine model.

Methods

A randomized animal study on swine model with induced acute respiratory distress syndrome (ARDS) was conducted. A dedicated room with controlled airflow was used to standardize the measurements obtained using an airborne optical particle counter. 6 ST and 6 PDT were performed in 12 pigs. Airborne particles (diameter of 0.5 to 3 μm) were continuously measured; video and audio data were recorded. The emission of particles was considered as significant if the number of particles increased beyond the normal variations of baseline particle contamination determinations in the room. These significant emissions were interpreted in the light of video and audio recordings. Duration of procedures, number of expiratory pauses, technical errors and adverse events were also analyzed.

Results

10 procedures (5 ST and 5 PDT) were fully analyzable. There was no systematic aerosolization during procedures. However, in 1/5 ST and 4/5 PDT, minor leaks and some adverse events (cuff perforation in 1 ST and 1 PDT) occurred. Human factors were responsible for 1 aerosolization during 1 PDT procedure. ST duration was significantly shorter than PDT (8.6 ± 1.3 vs 15.6 ± 1.9 minutes) and required less expiratory pauses (1 vs 6.8 ± 1.2).

Conclusions

COVID-19 adaptations allow preventing for major aerosol leaks for both ST and PDT, contributing to preserving healthcare workers during COVID-19 outbreak, but failed to achieve a perfectly airtight procedure. However, with COVID-19 adaptations, PDT required more expiratory pauses and more time than ST. Human factors and adverse events may lead to aerosolization and might be more frequent in PDT.

Published: November 2022

O uso inadequado do solo na produção agrícola vem provocando uma série de problemas, tais como a degradação dos recursos naturais e a exclusão social. Frente a esses problemas, a agricultura ecológica e a organização cooperativa de pequenos agricultores surgem como alternativas para a sustentabilidade da agricultura familiar. A produção e a comercialização de produtos cultivados de forma ecológica, e a importância do cooperativismo como meio de inserção socioeconômica e de participação política são os enfoques principais da pesquisa, realizada junto aos agricultores associados Ã  Cooperativa de Agricultores Familiares de Produtos Agroecológicos e Coloniais do Noroeste do Rio Grande do Sul LTDA - NATUAGRO, de Ijuí RS. Verificou-se que o sucesso e a viabilidade socioeconômica na produção ecológica dependem de diversos fatores: organização de mão-de-obra, estrutura fundiária, transporte, comércio. A organização cooperativa é um meio de inserção no mercado, e também um espaço de socialização, educação e poder político, que envolve toda a sociedade.

Empreendemos esforços para que o processo analítico transite entre as diferentes escalas geográficas, numa leitura dialética da atuação do capital internacional no espaço geográfico, com a elaboração de novos arranjos produtivos.

Este trabalho objetivou realizar uma análise do comportamento espectral das classes de cobertura vegetal do município de São João do Cariri - PB, no período de 1987 a 1996. Para tanto, utilizaram-se geoprocessamento e técnicas de sensoriamento remoto, como forma de entender a dinâmica da evolução frente à sucessão de estiagens ocorridas durante a década de 1990 e ante o aumento da demanda por produtos florestais, em decorrência do agravamento das condições de vida da população residente. As imagens analisadas foram obtidas pelo sensor TM/Landsat, órbita 215, ponto 65 e tomou-se como parâmetro o período chuvoso ou imediatamente após, objetivando, com isto, uma melhor resposta espectral do índice foliar, devido à exuberância da cobertura vegetal nesta época. Os resultados demonstraram que, no período analisado, verificou-se uma drástica redução das áreas cobertas por vegetação densa e semidensa, enquanto que as áreas de Caatinga rala e solos expostos cresceram, na mesma proporção. Também foi possível constatar que as áreas mais antropizadas, sobretudo as adjacentes aos rios, foram as mais afetadas, o que evidencia o aspecto social como condicionante da degradação da Caatinga.

O presente trabalho aborda a importância de um dos locais mais representativos na história do estado de Pernambuco e do Brasil, o Monte das Tabocas, que serviu de palco para o primeiro embate entre os luso-brasileiros e as tropas holandesas num episódio que deu início à expulsão dos holandeses do Brasil. O local aonde ocorreu essa tão importante batalha foi transformado em parque histórico estadual em 9 de novembro de 1978. Através de visita "in locoâ€? foi possível observar e diagnosticar a verdadeira situação de abandono do Parque. Diante do cenário encontrado, surgiu o objetivo central deste trabalho que foi realizar uma proposta de restauração e reestruturação para o Parque Histórico Estadual Monte das Tabocas, visando Ã  realização de atividades pedagógicas e turísticas. Desse modo, pode inferir, que o Parque Histórico Estadual Monte das Tabocas pode se tornar um gerador de demanda turística para o município de Vitória de Santo Antão. Assim, vê-se a necessidade de estruturar esse Parque para proporcionar aos futuros visitantes uma infra-estrutura adequada para o exercício de atividades como estudo, lazer ou recreação.

Published: November 2022

O crescimento e a urbanização das cidades brasileiras são realidade. Cada vez mais as atividades, de maneira geral, passam a ser gerenciadas pelo município. Este é o caso da gestão de áreas verdes e do turismo. Para o sucesso dessa ação, é necessário o uso de ferramentas modernas e acessíveis Ã  gestão pública. Em vista disso, o objetivo deste trabalho foi desenvolver uma banco de dados georreferenciado, em plataforma de sistemas de informações geográficas, para uso em gestão de áreas verdes e turismo, tendo como estudo de caso o município de Ourinhos-SP. Os resultados foram bastante satisfatórios, permitindo apresentar uma série de consultas ao banco, o que possibilitou realizar algumas análises, ainda que superficiais. O SIG usado foi o SPRING, de uso livre, e que se mostrou adequado a esta aplicação, além de ser acessível a qualquer órgão de gestão pública.
A URBANIZAÇÃO DO BRASIL E AS DIFERENTES DIVISÕES TERRITORIAIS DO TRABALHO AO LONGO DO TEMPO

Published: November 2022

Entender como os processos de urbanização vão se consolidando e vinculando interesses externos ao Brasil e, conseqÃ¼entemente, às diferentes divisões territoriais do trabalho ao longo do tempo se define como o objetivo deste artigo. Nossa hipótese trata o processo de urbanização como uma conseqÃ¼ência de interesses voltados a uma divisão territorial do trabalho, ou seja, entendemos que a urbanização vai refletir, de forma geral, o projeto de produção mundial, nacional, regional ou local e, conseqÃ¼entemente, quanto mais transformadas as produções, quanto mais adensadas, mais complexas se tornam as redes urbanas e as redes de relações. Para compreender como a divisão do trabalho se processa no Brasil propusemos uma breve periodização do processo histórico relacionado às diferentes divisões territoriais do trabalho, buscando esta possibilidade tanto como um exercício metodológico, quanto como possibilidade de pensar a história do ponto de vista das relações do espaço ou que se estabeleceram no espaço. Os períodos históricos foram definidos com base na tradicional divisão da historia do Brasil em períodos que assumem, por fins didáticos, as divisões entre período Colonial, Monárquico, Primeira Republica, Estado Getulista, Experiência Democrática e Regime Militar associado à transição deste para a Democracia.
DIÁLOGO ENTRE AS CIÊNCIAS SOCIAIS E A GEOGRAFIA
Authors: Queiroz Antonia Marcia Duarte
Published: November 2022

A ciência é considerada um conjunto de teorias e modelos que visam o conhecimento, a partir da aplicação de determinada metodologia em continuo processo de renovação. Observa-se constante busca de reflexões, sobre o conhecimento científico e os desafios que se apresentam nas ciências, a partir das necessidades humanas em constante construção e desconstrução. Nessa perspectiva, objetiva-se refletir sobre o conhecimento, por meio de análise comparada de alguns aspectos do desenvolvimento das ciências sociais e a formação do pensamento geográfico no tocante as discussões científicas modernas. Em âmbito metodológico essa abordagem utiliza-se da análise de literatura acerca de algumas idéias de Boaventura de Souza Santos, Milton Santos e Pierre Bourdieu que discutem sobre formas conceituais da formação epistemológica moderna.
REPRESENTAÇÃO SOCIAL DA MORADIA PARA A POPULAÇÃO DE BAIXA RENDA
Authors: Nóbrega Maria das Dôres Silva
Published: November 2022

O artigo objetiva compreender quais as representações sociais (RS) da moradia da população de baixa renda. A moradia é uma mercadoria tanto para a população de altos rendimentos como dos mais baixos rendimentos. O que diferencia é a maneira como o mercado imobiliário atende aos consumidores. Trabalha-se com a hipótese de que a RS da moradia para moradores de loteamentos periféricos se desenvolve, transmite-se e se mantém como história de sua vida. A coleta dos dados e informações das RS se dar por meio de entrevistas narrativas sobre a história de aquisição da moradia. Para isso desvendar as RS da moradia, o lócus do estudo é o município de Ã?guas Lindas de Goiás-GO. Como resultado da discussão observa-se o fenômeno da valorização da terra como fator determinante tanto da atração, quanto da expulsão da população mais pobre.

O presente artigo tem por objetivo discutir e compreender a importância que a atividade comercial teve para o nascimento e para a construção das cidades buscará, particularmente para a construção socioespacial da cidade de Macaíba, entre a segunda metade do século XIX e o início do século XX. Através da pesquisa bibliográfica e documental, analisamos a conjuntura econômica da Província do Rio Grande, no período em análise, deu a Macaíba, durante muitos anos, uma importância ímpar no conjunto dos municípios das regiões litoral e agreste, atraindo vendedores e compradores de diferentes localidades, o que a transformou no principal entreposto de comercialização da produção agrícola (açúcar, algodão e gado) advinda do litoral úmido e do interior do Estado.
A IMPORTÂNCIA DOS DADOS DAS VARIÁVEIS CLIMÁTICAS NAS PESQUISAS EM GEOGRAFIA: UM ESTUDO DE CASO EMPREGANDO A PRECIPITAÇÃO PLUVIOMÉTRICA
Authors: Oliveira Aristeu Geovani , Assunção Washington Luiz
Published: November 2022

O conjunto dos dados das variáveis climáticas constitui uma das bases fundamental para as pesquisas em Geografia, uma vez que estes oferecem uma série de informações primárias que, a partir de distintos métodos científicos, podem ser analisadas e discutidas, objetivando a elaboração de uma tese. Nas pesquisas geográficas que envolvem a climatologia e a meteorologia, os dados meteorológicos constituintes do sistema climático (variáveis climáticas) são os elementos sobre os quais a ciência se debruça para a elaboração de um caminho teórico-metodológico que culmine com a constatação de uma tese minuciosa e detalhada sobre o fato em questão. Assim, este texto é um ensaio que emprega uma análise primária de dados reais de precipitação pluviométrica relacionando-os com a produção de arroz no município de Jataí - Goiás, no período de 1990 a 2004, a fim de discutir a importância e significado do universo dos dados dos elementos do clima para o desenvolvimento das pesquisas em Geografia, neste caso em específico, relacionadas à produção agrícola.
COMÉRCIO SOLIDÁRIO E A COMERCIALIZAÇÃO DA SOCIOECONOMIA SOLIDÁRIA NO ESTADO DE MINAS GERAIS1
Authors: Gumiero Geisa Daise
Published: November 2022

O comércio constitui-se em um dos agentes que contribui para acentuar as diferenças sociais e econômicas entre países, causando desigualdade, injustiças e aumentando o número de excluídos. Nesse contexto, pelo descontentamento de alguns perante as injustiças causadas pelo mercado internacional de comércio, surge o comércio solidário. O comércio solidário ou comércio justo surgiu na Europa no século XX como uma possível tentativa de inserir o pequeno produtor no mercado e também de reduzir o número de atravessadores, garantindo melhores resultados financeiros a esses produtores, uma vez que o preço pago aos produtos solidários é maior que os dos outros produtos. Nesse sentido, destacam-se como principais produtos comercializados pelo comércio justo os produtos agrícolas e o artesanato, que em alguns casos são até exportados. Portanto, acredita-se que inserir o produtor no mercado através da comercialização de seus produtos constitui-se em uma forma muito mais eficaz de promover o desenvolvimento social e econômico, do que investir em políticas assistencialistas, que nada contribuem para o desenvolvimento do país. Diante do exposto, este trabalho tem como objetivo analisar a realidade do comércio solidário no país, especialmente no estado de Minas Gerais.
ANALÂNDIA/SP: DESENVOLVIMENTO DA INDÚSTRIA DO TURISMO E IMPLICAÇÕES AMBIENTAIS
Authors: Carmo Jean Pereira de Azevedo do
Published: November 2022

O município de Analândia possui os requisitos básicos para o sucesso de políticas públicas voltadas ao planejamento turístico, como atrativos naturais únicos, (como o Morro do Cuscuzeiro e o Morro do Camelo), vias de acesso de qualidade, sinalização, postos de informação, além de contar com uma relação de integração com outros centros turísticos que compõem sua região que acaba resultando na criação de circuitos turísticos. Esse agrupamento de municípios em circuitos turísticos insere-se na perspectiva desenvolvimento econômico-social/preservação ambiental das regiões interioranas do Estado como forma de reorganizar o espaço geográfico. A soma desses aspectos resulta na expansão da indústria do turismo, que já é visível no município, mas com o agravante de já apresentar impactos sociais e ambientais, principalmente nos pontos turísticos do município. Assim com a análise dos impactos podem-se incrementar as políticas públicas do município, para melhor planejamento e conseqÃ¼ente expansão do turismo, não deixando assim afetar o principal provedor dessa expansão, que são seus aspetos naturais.

Published: November 2022

Este trabalho tem por finalidade discutir o processo de transformação do território goiano nas últimas décadas do século XX para cá, quando o Estado se insere no circuito da modernização e do fluxo intensivo de capital. Nesse sentido, é importante abordar a importância do planejamento governamental relacionado com as demandas do capital nacional e internacional no processo de ocupação e apropriação do Centro-Oeste Brasileiro. A chegada da agricultura de exportação, da agroindústria e a consolidação do setor terciário com a sociedade informacional não podem ficar de fora dessa leitura. No primeiro momento será abordado o processo de intensificação da ocupação do território goiano provocado pela "Marcha para o Oesteâ€?, com a construção de Goiânia, consolidado pela construção de Brasília e pela chegada da modernização dos métodos de cultivo da agricultura no Cerrado Brasileiro. No segundo momento, serão apontados alguns pontos importantes da influência do desenvolvimento econômico de Goiás e seus efeitos na transformação sócioespacial das redes urbanas de Goiânia e Brasília com a intensificação dos fluxos migratórios. No terceiro momento, será realizada uma leitura do Goiás inserido no mundo das redes que controlam e comandam as transformações sócioespaciais, da complexidade que implica uma leitura de redes num território em constantes transformações.
