A REALIDADE PRODUTIVA DO SETOR SUCROALCOOLEIRO ALAGOANO NO PERÍODO DE 2008 A 2018
Authors: LIMA JOSE RODOLFO TENORIO
Published: March 2024

Diante da dinâmica que marca o setor sucroalcooleiro alagoano ao longo dos anos de sua história, o presente texto tem como objetivo analisar a realidade produtiva no período 2008 a 2018. São utilizadas as bases de dados oficiais ligadas a produção nacional agrícola como: Instituto Brasileiro de Geografia e Estatística (IBGE) e Companhia Nacional de Abastecimento (CONAB).  Também são utilizadas as bases de dados de organismos que representam o setor, em âmbito local, Sindicato da Industria do Açúcar e Álcool de Alagoas (SINDAÇÚCAR) e, nacional, União da Indústria da Cana-de-açúcar (UNICA). Pode ser percebido que ocorreu uma retração na produção alagoana em decorrência da crise que atingiu o setor sucroalcooleiro nacional e houve, consequentemente, perda de protagonismo no cenário produtivo brasileiro. Por fim espera-se que o texto possa contribuir para o debate sobre um setor que ainda possui grande representatividade na realidade socioeconômica alagoana. What do you want to do ?New mailCopy
ANÁLISE GEOMORFOLÓGICA DA BACIA HIDROGRAFICA DO RIO MUNDAÚ (PE/AL) A PARTIR DA APLICAÇÃO DE ÍNDICE DE HACK E INDICE DE SINUOSIDADE DE FRENTE DE ESCARPA
Authors: Melo Jonas , Monteiro Kleython
Published: March 2024

A análise quantitativa das drenagens tem sido uma prática sistematizada há pelo menos meio século. A relação destas com o relevo, entretanto, vem sendo aplicada desde os primórdios dos estudos geográficos/naturalistas. No intuito de contribuir para análises do relevo, foi aplicado o Índice de Hack (SL) no canal principal da Bacia Hidrográfica do Rio mundaú. Foram identificadas áreas anômalas de 1ª e 2ª ordem em seu perfil longitudinal, apresentando a existência de uma ruptura de patamar principal na cota de 250 metros. A partir desta definição, procedeu-se com a aplicação do Índice de Sinuosidade de Frente de Escarpa (Smf), verificando a ocorrência de diferentes setores com maiores e menores graus de influência de atividades tectônicas recentes, a depender do nível de detalhamento que se aplica. Por fim verificou-se que este método é eficaz na identificação e quantificação de anomalias e nos estudos de evolução do relevo, contribuindo com a compreensão geomorfológica regional.

Published: March 2024

La comuna de Andacollo se encuentra ubica en la pampa ondulada de los valles transversales de la cuenca hidrográfica del Arrayan, región de Coquimbo, al norte de Chile. Es una zona reconocida por la intensa actividad minera de extracción de cobre y oro, y por los inúmeros depósitos de relaves abandonados e inactivos en los alrededores de la zona urbana de la comuna. Es un área susceptible a inundaciones, destacando las ocurridas en 1997, 2015, 2017 y 2020. La dinámica hídrica en zonas de alto número de depósitos de relaves abandonados e inactivos puede representar un agravamiento potencial del riesgo, considerando el arrastre de metales pesados y la contaminación del agua y suelo. Como resultado, por medio de modelación matemática en SIG se identificó que, de los 108 depósitos de relaves instalados en la zona urbana de la comuna, 54 se encuentra instalados en zonas inundables.
Território e Circulação: Transformações no Transporte Rodoviário Brasileiro
Authors: Oliveira Neto Thiago
Published: March 2024

Os deslocamentos rodoviários no Brasil passaram por mudanças significativas nessas primeiras décadas do século XXI com a inserção de técnicas informacionais e a ampliação no volume e quantidade de pessoas e cargas deslocadas por veículo, ocasionando mudanças espaciais e organizacionais. Esse contexto de mudanças está diretamente vinculado com as necessidades econômicas das empresas na atualidade, centradas na fluidez, controle e potencialização do uso de máquinas e equipamentos. Para abordar tais transformações optamos em focar no controle cada vez maior das operações no atual contexto em que o meio-técnico-científico-informacional se torna cada vez mais candente. Nesse texto vamos abordar as mudanças nos veículos que deslocam cargas e passageiros nas rodovias brasileiras. Esse enfoque se justifica pelas alterações e que denotam singularidades que estão vinculadas com demandas econômicas das empresas que atuam nos segmentos de transportes.

REFLEXÕES SOBRE OS USOS E DESIGUALDADES TERRITORIAIS NOS MUNICÍPIOS DO TOCANTINS
Authors: Carloto Denis Ricardo , Santos Robson Francisco Barros dos
Published: March 2024

Este trabalho tem como objetivo refletir sobre os usos do território nos municípios tocantinenses. Para tanto utilizou-se de informações e dados oficiais sobre a distribuição espacial de hospitais, indústrias e empresas, bem como o índice da educação básica no estado do Tocantins.  Santos (2000) afirma que o território é usado por tudo e por todos e demonstra os que detêm mais capacidade de uso, atores hegemônicos, que utilizam o território como recurso; ou os que não detêm tal capacidade de uso, os atores hegemonizados, mas que têm o território como abrigo. A Constituição de 1988 firmou garantias à população brasileira que deveriam constituir usos mais igualitários do território brasileiro, refletidos em cada ente da federação, principalmente nos municípios. A representação espacial de temas ligados aos direitos sociais garantidos na Carta Magna de 1988 permitiram analisar os usos e as desigualdades nos municípios do estado do Tocantins.

Published: March 2024

A utilização dos espaços da casa e da rua para a oferta de comércio e/ou serviços pela população de menor poder aquisitivo atende a duas finalidades: suprir uma demanda de consumo e gerar renda. Este artigo objetiva analisar a presença do circuito inferior residencial nos conjuntos habitacionais, subsidiados pelo Programa Minha Casa Minha Vida (PMCMV) – Faixa 1 na Região Metropolitana de Natal (RMN), incluindo as residências unifamiliares e equipamentos urbanos. Os procedimentos metodológicos incluem revisão da literatura, pesquisa documental, identificação das unidades apropriadas para uso comercial ou prestação de serviços, evidenciadas através de um mapa de uso do solo e registro fotográfico. Os principais resultados da pesquisa apontam a operacionalização e validade de um aspecto da teoria dos dois circuitos da economia urbana, a saber: o circuito inferior residencial, pouco explorado na literatura. As análises demonstram que o circuito inferior residencial está presente no uso de parte da moradia ou na conversão da moradia em comércio e/ou serviços, recorrendo a novas e velhas estratégias para organização e gestão dos negócios, constituindo-se em novos usos do ambiente construído assimilando as condições de reprodução social dos moradores.
CENTENÁRIA TRAJETÓRIA DA NAÇÃO XAMBÁ: TERRITORIALIDADES DE UM TERREIRO-QUILOMBO NO BAIRRO DE SÃO BENEDITO (OLINDA)
Authors: Halley Bruno Maia
Published: March 2024

O trabalho aborda a centenária trajetória da Nação Xambá na grande periferia do rio Beberibe, na divisa das cidades do Recife e de Olinda, procurando revisitar as memórias e práticas da comunidade afro-religiosa quanto aos seus líderes, territórios e territorialidades reconstruídas, em especial nas últimas décadas quando da efetivação de um quilombo urbano nas cercanias do seu terreiro, no bairro olindense de São Benedito. Quanto aos procedimentos metodológicos, a pesquisa centrou-se na revisitação de estudos acadêmicos sobre a comunidade Xambá; na consulta de acervos de jornais de época; em visitas de campo ao quilombo e ao Museu Mãe Biu localizado no terreiro, onde foram consultadas fontes diversas e realizadas entrevistas com filhos de santo; e na confecção de cartas calcadas na localização dos xangôs do rio Beberibe e nas territorialidades do Xambá em seu terreiro-quilombo. Neste território se revelam variadas apropriações materiais e imateriais, que envolvem os afro-religiosos em redes de contatos com o poder público e agentes privados, engendrando maior visibilidade e conquistas ao povo de santo, redefinido nos últimos decênios como uma “neocomunidade” na reafirmação de suas identidades territoriais nas escalas do bairro e da grande periferia do Beberibe, malgrado aos preconceitos e estigmas dos contrários da crença.

HYDROCRAKING OF HEAVY DISTILLATE INTO CLEAN DIESEL OIL USING Ni-Mo/Al2O3 CATALYST
Authors: Nasution A.S. , Jasjfi E.
Published: March 2024

Diesel oil is high pollution fuel and the quality of this fuel must he improved to obtain clean diesel oil Crude oil production and its quality tend to decrease. Light fuel oil demand rate is higher than that of residual fuel. Diesel oil produced in the refineries generally consists of predominantly straight-run diesel oil: however, compounds such as thermally and catalytically cracked diesel oils are sometimes included. The quality of straight-run diesel oil, such as hydrocarbon types and sulfur content, will in general reflect the nature of crude oil. Cracked stocks either thermal or catalytic cracked diesel oils, contain higher percentage of aromatic, olefin and sulfur contents and these cracked diesel products must be hydrogenated prior to rounting to final products. The passage of the Clean Air Act Amendment of 1990 in the U.S.A has forced American refineries to install new facilities to comply with stricter specifications for fuels such as gasoline and diesel oil. Hydrocracking processes are a combination of desulfurization and conversion developed primary to process feeds having a high content of unsaturated hydrocarbons (olefin and polycyclic aromatics) and non-hydrocarbon compounds (sulfur and nitrogen compounds) with a bifunctional catalyst. A variety of bifunctional catalysts and processing designs may be used commercially depending on the feedstock used and desired products. Influence of both feedstock compositions (paraffinic and non-paraffinic vacuum distillate, and wax) and the acidity of bifunctional catalysts on the performance of hydrocracked diesel oil products are discussed briefly in this paper. Low yield or selectivity of diesel oil products by high catalyst acidity, it is suggested that the higher secondary splitting has taken place in converting cracked products into large amounts of low-molecular weight hydrocarbons such as gasoline and LPG. High diesel index product of the paraffinic feedstock due to the high paraffin content of the produced diesel oil.
LEMIGAS BIOSTRATIGRAPHIC DATA BANK CONSTRUCTION
Authors: Lelono Eko Budi
Published: March 2024

In accordance with the tasks and functions of LEMIGAS, the Stratigraphy Group of Exploration Division has been constructing a data bank of biostratigraphy which covers the whole areas of Indonesia. This project is financially supported by LEMIGAS and it has been started since 1997. The objective of this project is to collect biostratigraphic data across the Indonesian region. The data are differentiated into two types. The first type is raw data which were extracted from rock samples after laboratory preparation. The second type is data provided from the existing biostratigraphic charts. In addition, data generally derived from wells. Data obtained from the charts need to be re-analysed in order to gain accurate stratigraphic interpretation. The data bank is built by using a computer software called StrataBugs. This software was selected because it provides facilities to perform many types of biostratigraphic diagram which support different analyses. It is also compatible with other biostratigraphic software. The first five years were concentrated on western Indonesia. There are 285 data collected from various areas which consist of foraminifera, nannoplankton and palynology. Apparently, the number of data tends to increase each year.The data bank can be used for either scientific aims or managerial purposes. For scientific aims, these data are temporarily used for reconstructing biozones and palaeoenvironment. However, many analyses can be established by referring to these data such as palaeoclimate, sea level changes and palaeogeography. In fact, two papers have been published based on these data. For managerial purposes, these data may be used to evaluate the performance of Stratigraphy Group relating to commercial works because most data were supplied from service work. These data also support the management to prepare an appropriate strategy to achieve reasonable performance.

In reservoir simulation, the engineer needs a set of permeability values estimated on grid block which are as representative as possible of the true value. However. the sample data is limited to small scale measurement relative to the scale of reservoir simulation. Therefore. we need to upscale the permeability data measurement by averaging permeability on volumes. Prior to obtain the appropriate averaging method, an upscaling experiment was performed. The averaging method at the plug scale can be specified from the probe data and the Hassler cube data, by comparison.
THE ORIGIN OF DOLOMITE IN EARLY CAMBRIANCARBONATES OF YORKE PENINSULA, WESTERN MARGIN OF STANSBURY BASIN, SOUTH AUSTRALIA
Authors: Arifin Maximon Shah
Published: March 2024

The Early Cambrian carbonate sequence in Yorke Peninsula consists of tidal flat lithologies in the lower part (Kulpara Fomation) and lagoonal lithologies with sporadic bioherms (Koolywurtie Member) in the upper part. Dolomitization have been recorded in those carbonates mainly of replacive nature, only small amounts are void-fill cement. Petrographic and stable isotopic analysis have supported the conclusion that dolomitization of the Early Cambrian carbonates in Yorke Peninsula was an ongoing process by hypersaline water followed by a mayor episode of recrystallization during shallow burial diagenesis, where enormous quantity of magnesium required for regional dolomitization is supplied by sea water. The geochemical and tectural modification of the dolomites are the result of a later stage recrystallization event, in shallow burial diagenetic environment by surfacederived meteoric 1 water.

Published: March 2024

Study on pit closure guidelines for the oil and gas industries has been conducted by Lemigas Team to observe the existing guidelines in the implementation of the guidelines in the closure program of the temporary use of pits. Goals of the study are to review the manual guideline or standard operating procedure (SOP) of pit closure applied to the petroleum fields, and compare it to the relevant government regulation. So far, governmental regulation concerning pit construction and closure has not been established yet. Nevertheless, management approach of pir construction and closure can be established by referring to the available regulation, namely PP. 18/1999- hazardous waste regulation, and the related Ministerial Decree. This approach is based on the reason that such solid wastes are also categorized as hazardous wastes. Looking at from regulation point of view, it can be said that pit management guideline established by the industry has fulfilled and matched with the available regulation such as Kep.-04/Bapedal/09/1995. Nevertheless, some criteria have to be re-evaluated and post-closure plan seem not to be included in the guidelines vet. This paper presents the results of the study describing the existing guidelines used by the oil and gas industry and its implementation as well as reviewing the government regulation related to the pit closure program.

THE APPLICATION OF THE 't' TEST AND MARKOV CHAIN ANALYSIS IN BIOSTRATIGRAPHY OF 'X' WELL
Authors: Panuju Panuju , Firdaus Mufdi
Published: March 2024

There is no habit in biostratigraphers to apply the statistic methods to solve problems in their jobs, whereas in fact these methods are very useful when conventional ways failed. The use of this method has become very important in reservoir scale where microfossil content is low and indicator species is rare or absent. Applying biozonation in reservoir scale is much less reliable since reservoir layers are mostly below zonal resolution, so that the application of high resolution biostratigraphy is needed. In this case, the integration of biometric study and 't' or 'f' test can be used to define bioevent precisely. In sequence stratigraphy, data of depositional environment in various system tracts that determined using microfossil assemblage are very important. However, for the reasons of barren or no samples, this information might not be obtained by biostratigraphy or other methods. Due to the geological cycle and repeatable nature of depositional sequence, Markov Chain analysis can be used to predict the lost information about environment of deposition.

A Comparison Between Local Linear Regression and K- Nearest Neighbor Methods in Estimating the Nonparametric Regression Model with Simulation and Application
Authors: Sabur Saad , Dhia Hawraa
Published: March 2024

In this paper, the nonparametric regression model was estimated using two common estimation methods (Local Linear Regression Estimator (LLRE) and K-Nearest Neighbor Estimator (KNNE). The simulation process was conducted using the statistical programming language, R, for these methods, and they were compared using the Average Root Mean Squares Error (ARMSE) criterion, with three sample sizes (50, 100, 150), three levels of error variance (0.3, 0.7, 1) and two non-linear models. The results for the first model showed the superiority of the nearest neighbor estimator (KNNE) method in most cases, and for the second model the local linear regression estimator (LLRE) was superior at all sample sizes and for all levels of variance. On the applied side, the effect of hemoglobin (Hb) on the packed cell volume (PCV) of 150 patients with chronic kidney disease was studied. The estimation process was made using the two methods, and the comparison between them was made using the root mean square error (RMSE) criterion. It was shown through the results of the applied side that the preference was for the nearest neighbor estimator (KNNE) method.

The research was conducted to give an idea of the mechanism of transmission of the effect between political risk variables and the performance of the real estate sector، by presenting the most prominent real estate concepts and detailing the types of real estate، as well as building a quantitative standard model to test the impact of political risk implications (voting and accountability (AV)، political stability (PV)، government effectiveness (GE)، Regulatory Quality (RQ)، Rules of Law (RL)، Control of Corruption (CC)) on the performance index of real estate sector companies (return on equity (ROE)) for real estate sector companies registered in the Iraqi and Saudi financial markets، for the purpose of answering the question (Can the implications of political risks influence the performance indicators of the real estate sector?)، which represents the problem on which the study was based، for the time period 2011-2020. The study relied on the Pooled Mean Group method (PMG)، which is part of the environment of the autoregressive model for distributed time lags for Panel ARDL Model data in building the model and estimating the results، with the tests this method contains، and the quarterly data were approved for all variables of the study. The study reached several conclusions، perhaps the most prominent of which is that the impact of political risks was positive with the rate of return on equity in Iraq and this is because of the relationship between return and profit.

Authors: Sami Manar
Published: March 2024

The Iraqi economy is characterized as a rentier, unilateral economy that relies almost entirely on the oil commodity, while other productive sectors constitute a small percentage of the composition of the gross domestic product Which made it vulnerable to external shocks represented by fluctuations in oil prices in the global market and an imbalance in its production structure and as a result of the economic and political conditions that Iraq went through as well as fluctuations in global oil prices. It suffered from a weakness in infrastructure, and it greatly affected the Iraqi economy in terms of gross domestic product, the general budget, unemployment, etc. Therefore, it is necessary to know the effects that these shocks have on some indicators of the Iraqi economy, and this is considered an urgent necessity to explore future prospects. This research aims to study the impact of oil price shocks in the global market on some indicators of the Iraqi economy for the period (2004-2020)
Culture And Community: Sustainable Community Planning in the Rolling River First Nation
Authors: Connelly Sean , Markey Sean , Roseland Mark
Published: March 2024

Urban, rural and First Nations communities across the country face a growing infrastructure deficit. Sustainable community planning processes provide an opportunity to address this deficit in a way that both improves the quality of life for citizens and reduces environmental impact. However, there remains a gap between planning processes infused with sustainability principles and implementation. The purpose of this article is to explore this 'implementation gap' from a First Nations perspective. First Nations communities face particular capacity barriers and opportunities to conducting innovative and integrated planning. Using data drawn from a case study of Rolling River First Nation in Manitoba, the article illustrates how the community identified cultural traditions and the land base as critical components of their planning process. Both served to build the social infrastructure that provided the necessary capacity to bridge the planning - implementation gap.
Reframing Forest-Based Development As First Nation–Municipal Collaboration: Lessons from Lake Superior’s North Shore
Authors: Bullock Ryan
Published: March 2024

Changes in Northern Ontario's planning and policy context (e.g., forest tenure reform, Far North Act) are creating opportunities and obligations for First Nations and towns that often are not matched by the local capacity, resources, and governance structures requisite for effective and equitable participation. This paper documents the early stages of a First Nation-municipal forestbased development initiative in the Northeast Superior Region and interprets evolving perspectives of 27 First Nation and non-First Nation interviewees concerning the establishment of counterpart regional governance forums - the Northeast Superior Forest Community and Northeast Superior Regional Chiefs' Forum. The analysis shows how contrasting framings of common problems, solutions, identities, and power relations contributed to conflict but also innovation for eventual collaboration. First Nations acted on their obligation to teach other groups how they wanted to be engaged and the importance of developing culturally appropriate protocols to initiate and structure working relationships. First Nations and municipal representatives realized the need and benefit of redistributing different sources of power to strengthen their network and the common voice of the region. The conclusion offers lessons about building trust and relationships, the role of teaching and learning, and avenues to empowerment for fostering First Nation-municipal collaboration.
Balancing Politics and the Dispersal of Business Revenues among First Nations in Saskatchewan, Canada
Authors: Natcher David C. , Allen Tom , Schmid Trina
Published: March 2024

In this paper we present the results of interviews conducted with 14 First Nations in Saskatchewan on the ways in which they balance the need for economic development while meeting the social welfare needs of community members. Specific themes include (i) the separation between business and politics; (ii) the existence and role of boards of directors; (iii) strategic versus reactive decision-making; and (iv) the tension between revenue reinvestment and disbursement. Among the First Nations interviewed, three have put into place formal structures to separate business from politics, and have prioritized strategic and long-term investment over revenue dispersal. The remaining 11 First Nations use economic development as a vehicle to meet the social welfare needs of community members, including the funding of social program, Elders care, family allowances, and host of other social welfare services. This paper offers insight into the challenges First Nation governments encounter as they struggle to meet the diverse needs of their citizenry.

O desafio ambiental contemporâneo, marcado principalmente pelas emissões de gás carbônico na atmosfera que intensificam as mudanças climáticas, têm culminado em consequências planetárias já consideradas irreversíveis. Nesse sentido, este artigo busca enfatizar o Design para Adaptabilidade (DfAD) como prática projetual Biomimética a ser aplicada na Arquitetura, através da consideração ao ciclo de vida das edificações e a acomodação às mudanças. Para isso, realizou-se uma compreensão do Pavilhão de Pesquisa do ICD-ITKE 2013-14, destacando as vantagens quanto à lógica projetual, estrutural e material para artefatos efêmeros bioinspirados. Ressaltou-se, por fim, que o olhar à Natureza, como fonte de soluções e referências, mostra-se como uma alternativa de projeto para balancear e/ou reduzir os impactos advindos com as ações humanas desmedidas.

Pre-service teachers’ perceptions about the contributions of field work and construction of a physical model to modelling aquifers
Authors: Uskola Araitz , Seijas Nahia
Published: March 2024

Teachers are crucial to implement innovative activities in the classroom and to make them effective for their students’ learning. Teachers’ beliefs have been found to condition the extent to which and the way in which they carry out certain activities. This study analyses the beliefs of 73 pre-service teachers (two cohorts) about two resources (fieldwork and physical model) used in an aquifer modelling sequence in which they had participated. Their perceptions are compared with the hypothetical purposes of the resources in a modelling process. The data analyzed were the written reflections at the end of the activities. Both resources were rated very positively. Practically all participants referred to contributions to learning and many made metacognitive reflections. The results show that both resources met the expectations about their contribution to modelling. The implications for future design of modelling activities are discussed.
Perseverança e Desistência nos Seminários
Authors: Buss Tito
Published: March 2024

Acontecimento religioso da maior ressonância numa paróquia c sem dúvida a celebração das primícias de um neo-sacerdote, filho do lugar, consagrado para sempre ao serviço do Senhor. Por outro lado, é doloroso e desanimador, quando um cura de almas, após enviar diversos meninos ao seminário, com o correr dos anos, assiste ao regresso dêles, sem que um só alcance a almejada meta. Se foi sempre verdadeira a máxima do Evangelho: “muitos são os chamados, poucos os escolhidos”, em nossos dias, torna-se realidade assustadora. Ainda uma geração atrás – verifica-se pelas crónicas dos seminários maiores – era relativamente raro um filósofo ou teólogo deixar o seminário...
