Highlights

Arundo donax, Pennisetum purpureum, and P. purpureum × P. glaucum planted at 103 plants ha-1 were studied.

Biomass production and energy characteristics were evaluated at 12, 18, 24, and 30 months.

The production of dry biomass varied between 2.52 and 39.25 Mg ha-1.

The biomass quality and production of Arundo donax were different from those of Pennisetum ssp.

Abstract.The high global demand for fossil fuels has led to the search for alternative sources of renewable energy, such as the production of biomass from short-rotation crops (SRC). This study evaluated three grass species (, , and × ) in SRC systems planted at 103 plants ha-1 in humid tropical conditions in Costa Rica, considering biomass production, moisture content, and energy and chemical properties at four harvest ages (12, 18, 24, and 30 months). The results showed that the height of all species varied between 0.9 and 3.5 m at the different harvests, while the production of dry biomass varied between 2.52 and 39.25 Mg ha-1. As for their chemical properties, the ash content varied between 5.9% and 10.2%, volatile matter varied between 73.3% and 81.9%, and net calorific value varied between 15.86 and 18.94 MJ kg-1. In the three species, the production of biomass was greater at the 12-month and 18-month harvests; at later harvests, biomass production began to decrease, leading to increased moisture and ash contents, lower volatile matter, and lower calorific value. The biomass quality and production of were different from those of . Keywords: Bioenergy, Energetic potential, Forage, Pastures, Short-rotation plantations, Tropical species.
A Case Study on the Relevance of the Journal Impact Factor
Authors: Fox Garey A. , Fox Amanda K. , Guertault Lucie
Published: May 2020

Highlights

Publication profiles of seven highly published authors were analyzed from Google Scholar profiles.

Journal impact factor (JIF) not strongly correlated to citations in the first two years after publication.

Significant correlation between the number of citations in the first two years and total citations to an article.

More important to submit manuscripts to journals with appropriate readership than the highest JIF.

Abstract. In today’s world of research publishing, authors are typically encouraged to submit manuscripts to journals with the highest possible journal impact factor (JIF). This approach inherently assumes that the higher the JIF, the more likely the article will be cited. However, calls to move away from the JIF are becoming more common. This study analyzes the publication profiles of seven authors who are members of the Natural Resources and Environmental Systems (NRES) community of the American Society of Agricultural and Biological Engineers (ASABE) and who frequently publish in ASABE journals. This study hypothesized that statistically significant correlations existed between the JIF and the (1) total number of citations, (2) number of citations per year, and/or (3) number of citations in the first two years after publication. Based on 999 articles published by these seven authors from 1982 to 2018, statistically significant but fairly low to moderate correlations were observed between the JIF and the total citations, citations per year, and citations in the first two years after publication. The greatest correlation was observed between the number of citations that an article received in the first two years after publication and the number of citations per year (or the total number of citations). Therefore, ensuring an appropriate readership to generate short-term citations was more important than the JIF. When compared to high-JIF journals, there were statistically fewer citations per year and fewer citations in the first two years after publication for articles published in ASABE journals. While ASABE journal articles possess high citation longevity (i.e., cited half-life), efforts to immediately improve short-term metrics should focus on attracting high-quality research and improving article visibility. To extrapolate these findings to a wider community, future research should investigate these correlations for researchers in other ASABE technical communities and at various career stages. Keywords: Citations, Journal citation factor, Journal impact factor, Peer review, Research impact.
Dinâmica de Campos Térmicos Aplicada ao Estudo da Superposição de Estados Coerentes e Estados de Fock via Função de Wigner
Authors: Da Silva Filho Lourival Manoel
Published: May 2020

A estrutura algébrica da dinâmica de campos térmicos, o formalismo da teoria quântica de campos à temperatura finita e a tempo real, são usados para o estudo do estado composto pela superposição de um estado número de Fock, |n >, com um estado coerente, | \alpha >. A análise dos efeitos da temperatura é realizada considerando a matriz densidade e a função de Wigner. Para tal propósito, vamos considerar a duplicação do estado original com o estado de vácuo do espaço dual.

Estudo de velocidade de partículas associadas com flares solares
Authors: Almeida L. A. , Pereira M.G.
Published: May 2020

Neste trabalho, apresentamos um estudo referente aos fenômenos associados com as manchas e as erupções solares ("flares") que ocorrem na atmosfera do Sol. Resultados experimentais são obtidos com os instrumentos a bordo do satélite SOHO. Com os dados do Monitor de Prótons do instrumento CELIAS fazemos uma análise das partículas carregadas emitidas pelo Sol, os quais permitem a obtenção das velocidades de propagação das partículas aceleradas nos "flares". A utilização de medidas cinemáticas das velocidades oriundas das imagens das erupções observada pelo instrumento LASCO, permitiram a comparação destas com as do Monitor de Prótons. Em seis eventos observados pelo LASCO, as velocidades mostraram grande dispersão, em contraste com o observado pelo Monitor de Prótons. Tal fato indica que os "flares" ocorrem de forma isolada, não contribuindo de uma forma efetiva para a produção global das partículas detectadas pelo Monitor de Prótons.

O Letramento em Ciências como Objetivo para o Ensino de Ciências
Authors: Da Rosa Katemari Diogo , Martins Maria Cristina
Published: May 2020

Neste artigo apresentamos uma discussão sobre o significado de alfabetização científica e suas implicações para o ensino de ciências. Inicialmente discutimos a relação entre alfabetização e letramento e, em seguida, mostramos que o termo "alfabetização científica" abarca diferentes conceitos presentes na literatura através dos tempos. A importância dessa discussão emerge num ano em que o Brasil foi novamente submetido a uma avaliação comparativa de estudantesno que se refere à "alfabetização científica", o PISA (Programme for International Student Assessment). Essa avaliação, que teve início no ano de 2000, tem mostrado que somos um país que pouco sabe sobre ciência, pois o país logrou as últimas colocações nas avaliações de anos anteriores. A alfabetização científica vem se mostrando como um objetivo no ensino de ciências no Brasil e no mundo. Nesse sentido é importante que se discuta o que é alfabetização científica, para melhor entendermos e analisarmos as avaliações a que somos submetidos. Mais do que isso, para que possamos bem avaliar nosso trabalho, assim como planejar nossas ações didáticas.

Authors: Dos Santos Carvalho Jean Paulo , De Moraes Rodolpho Vilhena
Published: May 2020

Uma teoria para estudar o movimento orbital de satélites artificiais sobre efeitos do arrasto atmosférico e da pressão de radiação solar direta - considerando a sombra da Terra e alguns termos do geopotencial - é desenvolvida analiticamente. A sombra da Terra é modelada utilizando a função sombra (psi), como introduzida por Ferraz Mello: psi igual zero quando o satélite está na região de sombra e igual a um quando é iluminado pelo Sol. As componentes do arrasto são dadas por Vilhena de Moraes baseado no modelo atmosférico TD-88. O método de Hori para sistemas não-canônicos é aplicado para resolver as equações demovimento. Um software para manipulação algébrica é fundamental para fazer os cálculos necessários. Efeitos seculares e periódicos que influenciam no movimento orbital de satélites artificiais são analisados. Édada ênfase aos termos de acoplamento que surgem na soluçãodo sistema de equações diferenciais. Utilizando dados orbitais do satélite CBERS-1 é feito um estudo para analisar ordens de grandeza da variação do semi-eixo maior devidas às perturbações consideradas.
O Campo de Radiação Quantizado sob Vínculos Macroscópicos e a Pressão de Casimir no Calibre de Coulomb
Authors: Farias Franz A. , Neto A. Matos
Published: May 2020

O presente trabalho determina a pressão de Casimir seguindo as ideias da Eletrodinâmica Quântica Finita (Finite QED), i.e., construímos uma expressão para o tensor energia-momento (E-M) do campo de radiação quantizado de maneira a eliminar qualquer procedimento posterior de renormalização na obtenção de resultados finitos para os observáveis físicos, em particular, para a energia e o momento. O ponto de partida para este desenvolvimento é uma proposta de produto de operadores a ser utilizada na construção de observáveis, para os quais as medidas físicas sejam sempre resultados finitos. Com esta motivação, desenvolvemos o cálculo da pressão de Casimir no calibre de Coulomb considerando dois tipos de condições de fronteira: a de Dirichlet e a de Neumann.
Notas sobre o Grupo de Galileu: Aspectos Geométricos e Recentes Desenvolvimentos
Authors: Abreu Luciano M. , Santana Ademir E. , Santos Esdras E. , Filho Aurino Ribeiro
Published: May 2020

Apresentamos uma revisão pedagógica sobre as simetrias galileanas, seus desenvolvimentos e o interesse atual na geometria do espaço-tempo não-relativístico para fins de aplicação. Inicialmente tratamos de alguns aspectos históricos e seguimos com a definição do grupo de Galilei; nos concentramos depois na noção de covariância Galileana. Enfatizamos o estudo de representações que levam a equações da mecânica quântica não-relativística, como a equação de Schrödinger para partículas de spin zero e a equação de Pauli-Schrödinger para partículas de spin 1/2. A forma como as representações são construídas torna evidente, para fins pedagógicos, que conceitos como o spin, não são efeitos tipicamente relativísticos, como aparecem em alguns textos sobre mecânica quântica. Por outro lado, reforçamos a importância da estrutura tensorial (geométrica) para aplicações em sistemas não-relativísticos, como no caso da física da matéria condensada.
‘We’ve got a file on you’: problematising families in poverty in four periods of austerity
Authors: Horsley Nicola , Gillies Val , Edwards Rosalind
Published: May 2020

This article considers a genealogy of the governing by data of families in poverty; a case study of the codification of disadvantaged families and problematisation of their difficulties over the course of a century and a half. Influenced by Bacchi’s ‘what the problem is represented to be’ approach, we explore a genealogy of the micro acts of ruling that reveal the practice of constructing and governing of disadvantaged families. We draw on a case study analysis of materials recorded and collected by the Charity Organisation Society and its subsequent guises, during four major periods of recession in Britain, from the late 19th century to the early 21st century. We outline the ‘problematisation’ approach to governance that underpins our discussion before describing the administrative records with which we worked. We argue that the genealogy of the construction, positioning and governance of poor families over time in this case may be observed in terms of three key shifts in problematisation: (i) from the identification of deservingness towards the assessment of risk; (ii) from a gendered concentration of parents to the perceived needs of children; and (iii) from consultation of authority figures to a reliance on increasingly ‘professionalised’ data capture tools.
Characterization of natural frequencies from nanoscale tissue oscillations using dynamic optical coherence elastography
Authors: Lan Gongpu , Larin Kirill V. , Aglyamov Salavat , Twa Michael D.
Published: May 2020

We demonstrate the use of OCT-based elastography for soft-tissue characterization using natural frequency oscillations. Sub-micrometer to sub-nanometer oscillations were induced in tissue phantoms and human cornea in vivo by perpendicular air-pulse stimulation and observed by common-path OCT imaging (sensitivity: 0.24 nm). Natural frequency and damping ratio were acquired in temporal and frequency domains using a single degree of freedom method. The dominant natural frequency was constant for different stimulation pressures (4-32 Pa) and measured distances (0.3-5.3 mm), and decreased as the sample thickness increased. The dominant natural frequencies of 0.75-2% agar phantoms were 127-774 Hz (mean coefficient of variation [CV]: 0.9%), and correlated with the square root of Young’s moduli (16.5-117.8 kPa, mean CV: 5.8%). These preliminary studies show repeatable in vivo corneal natural frequency measurements (259 Hz, CV: 1.9%). This novel OCE approach can distinguish tissues and materials with different mechanical properties using the small-amplitude tissue oscillation features, and is suitable for characterizing delicate tissues in vivo such as the eye.
Clyde Hopkins: Abstraction as experience
Authors: Key Joan
Published: May 2020

Hopkins’ painterly abstraction reflects on a universe of disordering contingencies in everyday experience, questioning how painting can refer to such qualities of experience without engaging in representation. The immediate act of placing paint on the canvas extends to metaphorical concerns with process: how to maintain that sensation of immediacy if repetitions occur within a sequence of gestural responses. Hopkins’ work adopts different approaches at different stages; degrees of immediacy remain a consideration while attachment to a variety of motifs develops. Paintings remain continuously open to change as more reflexive approaches to the ironies of maintaining immediacy in re-presentation emerge. Resources are both visual and philosophical: the questioning of logic with ‘associationism’ found in the writings of David Hume and influencing Lawrence Sterne, a fascination with Spanish painting and its influence on Robert Motherwell, who was in turn influenced by A. N. Whitehead.

Published: May 2020

A 42-year-old African American woman presented with 4 days of worsening midepigastric pain that radiated to her back. Computed tomography confirmed a diagnosis of acute pancreatitis and revealed a mass within the distal body and tail of the pancreas. After an endoscopic ultrasound with fine-needle aspiration yielding atypical cells suspicious for adenocarcinoma, the patient underwent an en bloc resection of the intra-abdominal mass with subtotal pancreatectomy, splenectomy, left colectomy, and left partial adrenalectomy. Histopathologic examination findings, in addition to immunohistochemical staining, revealed a diagnosis of pancreatic carcinosarcoma. Postoperatively, the patient has undergone 20 cycles of chemotherapy and has been transitioned to comfort measures at 16 months postoperatively because of progressive disease.

Published: May 2020

Ganglioneuromas are rare benign tumors of neuroblastic origin that can occur anywhere along the sympathetic chain. They are rarely found in the gastrointestinal tract and can appear as solitary polypoid lesions or diffuse as part of a familial syndrome. They are often asymptomatic but may present with nonspecific symptoms depending on their anatomic location. They have no special endoscopic appearance and are diagnosed by histology and immunohistochemistry staining. We present a case of solitary gastric ganglioneuroma treated successfully with endoscopic resection.
Escolas de memórias: representações da escola entre novos letrados (Minas Gerais, décadas de 1900 a 1930)
Authors: Fadul Cecília Rodrigues , Galvão Ana Maria de Oliveira
Published: May 2020

O artigo teve como objetivo analisar as representações de escola que autores(as) de autobiografias – nascidos(as) em Minas Gerais a partir do final do século XIX e considerados novos letrados – construíram ao longo de suas trajetórias de vida e produziram em suas obras. Foram analisadas sete autobiografias, compreendidas como documentos significativos para se alcançar as experiências pessoais de um grupo que construiu representações singulares sobre a escola. Chegou-se à conclusão de que a escola, para os novos letrados, foi supervalorizada, sobretudo como mecanismo de inclusão em uma sociedade que, ao longo dos anos - entre o tempo das memórias e o tempo da escrita - viu crescer a valorização da escolarização e da alfabetização. Os(as) autores(as) buscaram, por meio da escola, se incluírem no grupo daqueles que, pela via do conhecimento, ocupava lugares de distinção. A escrita de um livro pareceu configurar o desfecho ideal dessa ascensão simbólica.
Formas de organizar a Educação Física no ensino primário: memórias de professoras da Escola Giuseppe Garibaldi, Caxias do Sul/RS (1974-1985)
Authors: Giacomoni Cristian , Souza José Edimar de
Published: May 2020

Este estudo analisa narrativas de duas professoras primárias da Escola Giuseppe Garibaldi, cujas memórias auxiliaram na compreensão das formas de organização das aulas de Educação Física. Pretendemos recompor as possíveis histórias do ensino neste local, desde a fundação da escola em 1974 até 1985, ano do término do regime civil militar. A perspectiva teórica é da História Cultural, e utiliza a metodologia da História Oral, mediante as memórias das professoras Jacira Koff Saraiva e Jaqueline Gedoz Vita. Para Halbwachs (2006), as possíveis narrativas históricas de um contexto são constituídas pelos compilados de fatos que se destacam, e que são selecionados pelas memórias dos sujeitos. Essas memórias estão interligadas aos convívios sociais e podem ser influenciadas pelos diversos âmbitos em que o sujeito está imbricado. As evidencias apontam que as aulas de Educação Física eram organizadas a partir dos conhecimentos docentes, fundamentados pelas brincadeiras e esportes, porém sem a concepção competitivista.
El derecho a la educación y su desarrollo conceptual desde una perspectiva histórica
Authors: Ruiz Guillermo Ramón
Published: May 2020

En este artículo se realiza una conceptualización del derecho a la educación a partir de una perspectiva histórica. En primer lugar, se analiza la historicidad de este derecho, en el marco del desarrollo del liberalismo y del constitucionalismo como procesos convergentes en la configuración de los Estados nacionales modernos. En segundo lugar, se plantean definiciones derivadas del desarrollo del derecho internacional de los derechos humanos y de la propia definición de la educación como un derecho humano fundamental. Finalmente, se presenta un planteo problemático de los alcances de la educación como derecho en función de los procesos históricos recientes de reformas educativas, implementadas por gobiernos de la moderna derecha, las cuales han promovido la privatización educativa.
A supremacia da escrita sobre a oralidade: uma análise de práticas matemáticas de sujeitos de região de colonização alemã
Authors: Kroetz Ketlin , Gallon Mônica da Silva , Ferraro José Luis Schifino
Published: May 2020

Este artigo problematiza algumas práticas matemáticas escritas e orais de colonos descendentes de alemães de região de colonização alemã do Vale do Rio dos Sinos, e objetiva verificar como as mesmas foram utilizadas por esses sujeitos tanto no período escolar, quanto em suas atividades laborais agrícolas. Os aportes teóricos utilizados para essa investigação estão fundamentados, principalmente, nos estudos de Weber (2002), evidenciando que práticas matemáticas orais se sobressaem nas atividades laborais desses sujeitos, enquanto que no período escolar se observa a legitimação de uma matemática caracterizada pela escrita, evidenciando uma supremacia da escrita sobre a oralidade ao longo da escolarização. Nesse sentido, a utilização de práticas que se valham da oralidade pode converter-se em possibilidade para um constante (re)pensar a educação matemática, uma vez que a escrita prepondera em diferentes instâncias do contexto escolar, produzindo subjetividades que empoderam tal discurso conferindo-lhe o status de único modo possível de matematizar.
Pasajes en Ecologías Emergentes del Dramaturgear (Dramaturgying)
Authors: Hernández Álvaro
Published: May 2020

Este ensayo se propone reflexionar sobre los momentos sentidos a través de la acción de prácticas particulares en el hacer de un performance, cuando ni siquiera se ha manifestado alguna idea de resolución, ni la coherencia de su sustancia particular se ha materializado en términos definibles, sino más bien cuando un sentir sentido de no-conocer atrae las relaciones de la acción a un efecto indefinido. Tal condición particular es lo que llamo Dramaturgear (Dramaturgying) y el espacio tiempo afectivo en el que ocurre es ensayo. El espacio de indeterminación que es atravesado por la materialización producida por el entretejido de fuerzas y relaciones transportadas por una práctica puede activar la potencialidad de un campo de relaciones en el cual la emergencia de otro tipo de coherencias y sensorios puede ser hecha posible. Esta pieza se desarrolla a través de trabajo en prácticas localizadas y situadas en relación a materiales particulares que permiten la emergencia con/de distintos sensorios en el entorno de ecologías. Cada una de estas prácticas con materiales activa co-composiciónes afectivas de tiempo-espacio, que se mueven en el curso de las conexiones emergiendo de la experiencia en el ensayo, permitiendo nuevas potencialidades y la apertura a otro tipo de relaciones humanas y otras que humanas. Cada práctica es un experimento en dramaturgia procesual que ocurre en un entorno en el que emergen zonas de contacto que difuminan y expanden los límites del límite en la emergencia del dramaturgear. Son experimentos que arriesgan cuerpos al borde.
Insurance-markets Equilibrium with a Non-convex Labor Supply decision, Unobservable Effort, and Incentive ("Fair") Wages
Authors: VASILEV Aleksander
Published: May 2020

The purpose of this note is to describe the lottery- and insurance-market equilibrium in an economy with non-convex labor supply decision, unobservable effort, and incentive ("fair") wages. The presence of indivisible labor creates a market incompleteness, which requires that an insurance market for employment be put in operation to "complete" the market.

In this lecture note we define the S bases for the spaces of tempered distributions.These new bases are the analogous of Hilbert bases of separable Hilbert spaces for the continuous case (they are indexed by m-dimensional Euclidean spaces) and enjoy properties similar to those shown by algebraic bases in the finite dimensional case.The S bases are one possible rigorous and extremely manageable mathematical model for the "physical" bases used in Quantum Mechanics.
Assessment of IEC Normal Turbulence Model and Modelling of the Wind Turbulence Intensity for Small Wind Turbine Design in Tropical Area: Case of the Coastal Region of Benin
Authors: Donnou Hagninou Elagnon Venance , Akpo Aristide Barthélémy , Houngue Guy Hervé , Kounouhewa Basile Bruno
Published: May 2020

The wind turbulence intensity observed on a site have an influence the wind turbine energy production and the lifetime of the blades. It is therefore primordial to master this parameter for the optimization of the production. So therefore, this study is interested on the modelling of the wind turbulence intensity at 10 m above the ground on the coast of Benin. Four years of wind data measured on the site of Cotonou Port Authority (PAC) from 2011 to 2014 and recorded with a temporal resolution of 10 min were used. From the transport equation of turbulent kinetic energy followed by a numerical simulation based on the Nelder-Mead algorithm developed under the Matlab software, we proposed five new models for estimating the wind turbulence intensity. The results of the different simulations reveal that four of proposed models and based on the roughness, the speed of friction and the length of Obukhov better fit the data, during the periods of January, April, June, July, August, September and December. The estimators of the Root Mean Square Error (RMSE) and the Mean Absolute Error (MAE) vary from (0.02; 0.01) in December to (0.09; 0.07) in August. As for the model  which is a function of roughness and the wind  shear coefficient (expressed only according to the wind speed), it gives better performance whatever the time of the year and the atmosphere stability conditions. The estimations errors are included between (0.02; 0.01) obtained in December and (0.08; 0.06) observed in March. A comparative study between the existing models in the literature and the best model proposed in this study showed that only this model gives the best adjustment with the data. It can therefore be used on the sites where turbulence is influenced by the roughness and the atmosphere stability. Finally, from this model a new wind turbine design class has been proposed for the site of Cotonou. It takes into account the actual levels of turbulence observed and thus allow to optimize the energy production.

Characterization of Microstructure and Fracture Performance of Boronized H11 Grade Hot-Work Tool Steel
Authors: Jurči Peter , Hudáková Mária
Published: May 2020

H11 grade hot-work tool steel was subjected to powder boronizing at 1,030°C for different processing times. Subsequently, the steel was austenitized, quenched, and tempered to a bulk hardness of 47–48 HRC. The microstructure, phase constitution, and hardness of boronized layers were examined using scanning electron microscopy and microanalysis, glow discharge optical emission spectroscopy, X-ray diffraction, and microhardness measurements. The effect of the boronized region on the material fracture performance was examined using the Charpy impact test, according to the corresponding standard NADCA 202-97, Recommended Procedures for H13 Tool Steel. It was determined that the growth of the boronized layer begins with a boron enriched α-phase. Then, the (Fe,Cr)2B boride was developed, and in the case of longer processing time, the (Fe,Cr)B boride was grown. During boronizing, carbon atoms were transported from the surface toward the bulk, forming extra carbides beneath the compound regions. Their amount increased with increasing boronizing duration, which was reflected in the enhanced hardness of the intermediate region beneath the compound boronized layer. The microhardness of (Fe,Cr)2B boride layers was around 1,600 HV 0.1, and the microhardness values of (Fe,Cr)B considerably exceeded 2,000 HV 0.1. However, boronizing led to a substantial reduction of the Charpy impact toughness of the material, and this reduction was more pronounced when a thicker compound layer was formed on the steel surface. The reduction in toughness was clearly reflected on the fractured surfaces as they manifested clear cleavage fracture propagation.
La démographie rurale : des évolutions différenciées selon les territoires ruraux

Published: May 2020

Notre analyse de l’évolution de la démographie rurale québécoise, basée sur des données objectives,permet d’illustrer des réalités souvent méconnues ou mal perçues, par exemple la croissance globalement positive de la population vivant en milieu rural. Nous proposons ici une typologie originale des milieux ruraux qui permet de mieux faire ressortir la dynamique des évolutions démographiques rurales. Dans un deuxième temps, nous étudions l’évolution des migrations selon cette typologie, qui illustre un ralentissement significatif de ce qu’on appelle l’exode rural et le ralentissement du pouvoir d’attraction de Montréal. Finalement, le vieillissement de la population rurale, avec maintenant plus de décès que de naissances, devient un facteur décisif de l’évolution de la démographie rurale du Québec.

Le vieillissement de la population représente un défi incontournable pour le Québec, en particulierpour les milieux ruraux, plus affectés par ce phénomène. L’objectif de cet article consiste à examiner la trajectoire évolutive du vieillissement au sein des localités rurales du Québec au cours de la période 1986-2016. Les résultats sont exposés à partir d’une analyse typologique à trois niveaux réunissant des localités qui présentent certaines affinités eu égard à l’évolution et à l’intensité du vieillissement. L’analyse est effectuée suivant une approche géographique et socioéconomique. Parmi les 62 localités rurales les plus enclines au vieillissement, la plupart présentent des signes de fragilité sur les plans démographique, géographique et économique, ce qui témoigne du caractère structurel des différents malaises auxquels elles font face. La combinaison de ces difficultés contribue à handicaper leur développement, en plus d’avoir des impacts négatifs sur leurs perspectives d’avenir, d’où la nécessité de mettre en place une politique d’aménagement du territoire et de développement régional qui va bien au-delà d’une stratégie tournée uniquement vers le vieillissement démographique.
Les néoruraux en cavale vers la campagne : quelles conséquences pour le Québec?
Authors: Guimond Laurie , Simard Myriam
Published: May 2020

La migration vers les campagnes de populations d’origine urbaine, qu’on surnomme les néoruraux,s’effectue à l’échelle du Québec, autant dans les régions adjacentes aux grands et moyens centres urbainsde la vallée laurentienne qu’ailleurs dans la province. Cet article s’intéresse à leur profil et aux motivations quijustifient la concrétisation de leur projet migratoire. En outre, il explore les conséquences multiformes de leurétablissement à la campagne, tout en proposant certaines pistes d’action pour répondre aux défis sous-jacentsau phénomène de néoruralité.
La ruralité contemporaine face aux changements climatiques : étude de l’adaptation sur les littoraux touristiques d’une petite ville québécoise
Authors: Guillemard Alexis , Lapointe Dominic
Published: May 2020

En études urbaines ou régionales, les petites et moyennes villes (PMV) forment une catégoriedifficile à classer. En périphérie, ces territoires hybrides comprennent des signes de l’urbain, mais aussi certaines fonctions associées à la ruralité (p. ex., agriculture et conservation). Le tourisme y est souvent désignécomme une solution au recul agricole et à la désindustrialisation. Pourtant, en situation littorale, le secteurtouristique des PMV dépend d’un environnement fragile, soumis à divers événements naturels amplifiés parles changements climatiques. Au Québec, les littoraux de l’estuaire du Saint-Laurent font face à plusieurs pressions liées aux transformations du climat : accélération de l’érosion côtière, diminution du pied de glace, incertitudes autour des tempêtes, submersion, etc. C’est notamment le cas à Rivière-du-Loup, petite ville du Bas- Saint-Laurent. À l’aide de la théorie de la production de l’espace (Lefebvre, 1974/2000), nous essayons demettre en lumière les principaux enjeux pour l’adaptation du territoire touristique louperivois. Nous nousbasons sur certains résultats préliminaires d’une recherche-action en mode living lab que nous avons menée de 2016 à 2019.
Les trois vi-e-s des territoires ruraux : voyage en France ou ailleurs
Authors: Lardon Sylvie
Published: May 2020

Les territoires ruraux changent : ils nouent de nouvelles relations avec le monde urbain. La planètes’urbanise : elle est le siège de nombreux flux. Ces dynamiques, qui s’étendent sur de larges espaces, occultent celles qui se déroulent à proximité, à faible densité, dans les territoires où pourtant on assiste à un foisonnement d’initiatives. Or, ce sont des territoires vivants qui transforment le monde en articulant l’urbain et le rural, en assumant une solidarité réciproque, en dépassant les limites et les frontières. Pour accompagner ces dynamiques de changement, l’ingénierie territoriale se doit de favoriser l’interterritorialité, l’intégration des échelles et des mondes ainsi que la reconnaissance des innovations sociales et territoriales. Plus encore, elle doit impliquer l’ensemble des acteurs qui sont partie prenante pour donner vie aux territoires en se construisant une vision partagée du territoire et en mettant en oeuvre des actions collectives, en les ancrant dans le territoire et en les rendant visibles et sensibles. Ce cadre conceptuel d’une ingénierie territoriale pour, par et avec les territoires ruraux est issu d’une recherche partenariale en cours avec le territoire du Grand Clermont et du parc naturel régional Livradois-Forez, en région Auvergne- Rhône-Alpes, en France, qui « invente les territoires de demain » autour de son projet alimentaire territorial. Il y a là de nouvelles pistes à explorer qui remettent en cause les procédés traditionnels de production scientifique et de construction de l’action. La rigueur des itinéraires méthodologiques construits et la diversité assumée des dispositifs permettent de monter en généricité. L’imagination valorise cette diversité et produit le futur des territoires.

Antosianin merupakan pigmen pewarna alami yang berwarna dan dapat berperan sebagai antioksidan. Senyawa ini dapat digunakan sebagai salah satu bahan tambahan makanan sebagai pewarna. Selain peranannya sebagai zat warna, antosianin juga dapat berperan sebagai senyawa antioksidan, sehingga ketika ditambahkan pada makanan akan menghasilkan suatu pangan fungsional. Salah satu bahan yang kaya akan antosianin adalah ubi jalar ungu (Ipomoea batatas L.). Tujuan dari penelitian ini adalah untuk mengekstraski antosianin dari ubi jalar ungu. Metode yang dilakukan meliputi preparasi antosianin melalui maserasi dengan etanol, pemekatan dengan teknik evaporasi vakum ekstrak ubi ungu, karakterisasi spektrum sinar tampak serta penentuan residu etanol pada ekstrak. Hasil yang diperoleh menunjukkan bahwa dari 500 g ubi jalar ungu segar yang diekstraksi dengan 1 L etanol diperoleh 8 g pasta ekstrak ubi jalar ungu. Karakterisasi dengan spektrofotometri pada pajang gelombang sinar tampak menghasilkan spektrum yang sama dengan spektrum yang telah dipublikasikan sebelumnya. Ekstrak yang diperoleh memiliki aktivitas antioksidan yang cukup tinggi dengan nilai konsentrasi inhibisi 50 (IC50) sebesar 41,1±7,3 ppm. Karena tujuan ekstraksi ini adalah untuk aplikasi pada bidang pangan, residu etanol yang terdapat pada ekstrak ditentukan dengan metode enzimatik menggunakan alkohol dehidrogenase dan diperoleh residu etanol sebanyak 0,122 ±0,033% v/v.

Teknik ekstraksi fase padat (solid phase extraction, SPE) telah banyak menggantikan ekstraksi cair-cair karena sifatnya yang lebih ramah lingkungan dengan menggunakan volume pelarut lebih sedikit, waktu yang cepat dan proses yang mudah.  Namun demikian, selama ini adsorben  yang umum digunakan pada SPE adalah silika atau polimer dari bahan kimia yang memerlukan teknologi tinggi sehingga harga SPE di pasaran relatif masih mahal untuk digunakan di laboratorium yang ada di Indonesia.  Oleh karena itu dalam penelitian ini dipelajari pemanfaatan karbon aktif sekam padi untuk penentuan salah satu senyawa polisiklik aromatik hidrokarbon (PAH), yaitu fenantrena.  Limbah sekam padi diketahui dapat dimanfaatkan menjadi karbon aktif sebagai alternatif adsorben unggulan dari limbah pertanian yang terbarukan, murah dan melimpah di Indonesia termasuk di Lampung. Faktor yang mempengaruhi ekstraksi SPE seperti waktu ekstraksi, massa adsorben, konsentrasi  adsorbat dan pH akan dievaluasi.  Uji kinerja metode SPE untuk penentuan PAH akan ditentukan berdasarkan parameter akurasi, presisi dan linearitas.  Hasil penelitian menunjukkan kondisi optimum untuk waktu ekstraksi adalah 60 menit, massa konsentrasi adsorbat 10 ppm, massa adsorben 25 mg pada pH 3. Hasil uji kinerja analitik menggunakan parameter akurasi, presisi, dan linearitas telah memenuhi syarat keberterimaan yang menunjukkan bahwa metode SPE sebagai preparasi sampel untuk menentukan fenantrena di perairan dapat digunakan.
