Conceptualizing Integrative Agricultural Education: Introductory Framework for Integrating Mathematics in Agricultural Curriculum
Authors: Robinson Kelly , Westfall-Rudd Donna , Drape Tiffany , Scherer Hannah
Published: December 2018

A curriculum framework to support the integration of academic content to support students’ development of 21st century skills including critical thinking and problems solving skills is notably absent from agricultural education. An integrative agricultural education framework is conceptualized through a review of literature in STEM education to establish integrative teaching practices. A focus on the development of students’ quantitative reasoning skills through agriculture content hones the focus of the curriculum framework. Quantitative reasoning is the ability to confidently approach unique and complex problems in a real-life context by applying mathematical skill, knowledge, and reasoning. The integrative agricultural education framework developed was used to design an evaluative rubric for teachers, administrators, and curriculum designs to use as a tool for building both integrative teaching and mathematics into agricultural education curriculums intentionally and fluidly.

Abstract. Global three-dimensional data are a key to understanding gravity wave interactions in the mesosphere and lower thermosphere. MATS (Mesospheric Airglow/Aerosol Tomography and Spectroscopy) is a new Swedish satellite mission that addresses this need. It applies space-borne limb imaging in combination with tomographic and spectroscopic analysis to obtain gravity wave data on relevant spatial scales. Primary measurement targets are O2 Atmospheric Band dayglow and nightglow in the near infrared, and sunlight scattered from noctilucent clouds in the ultraviolet. While tomography provides horizontally and vertically resolved data, spectroscopy allows analysis in terms of mesospheric temperature, composition, and cloud properties. Based on these dynamical tracers, MATS will produce a climatology on wave spectra during a 2-year mission. Major scientific objectives concern a characterization of gravity waves and their interactions in the mesosphere and lower thermosphere, as well as their relationship to dynamical conditions in the lower and upper atmosphere. MATS is currently being prepared for launch in 2019. This paper provides an overview over scientific goals, measurement concepts, instruments, and analysis ideas.
Antarctic clouds, supercooled liquid water and mixed-phase
investigated with DARDAR: geographical and seasonal variations

Published: December 2018

Abstract. Antarctic tropospheric clouds are investigated using the radar-lidar DARDAR (raDAR/liDAR)-MASK products. The cloud fraction is divided into the supercooled liquid water (SLW)-containing clouds and the all-ice clouds. The low-level SLW fraction varies according to temperature and sea ice fraction. It is the largest over water. In East Antarctica, the SLW fraction decreases sharply polewards. It is twice to three times higher in West Antarctica. The all-ice cloud geographical distribution is shaped by the interaction of the main low-pressure systems surrounding the continent and the orography, with little links with sea ice fraction. We demonstrate the largest impact of sea ice on SLW (mostly mixed-phase clouds, MPC) in autumn and winter, while it is almost null in summer and intermediate in spring. Monthly variability of MPC shows a maximum fraction at the end of summer and minimum in winter. Conversely, the unglaciated (pure) SLW (USLW) fraction has a maximum at the beginning of summer. Monthly evolutions of MPC and USLW fractions do not differ on the continent. This demonstrates a seasonality in the glaciation process in marine liquid-bearing clouds. From the literature, we identify the pattern of the monthly evolution of the MPC fraction as being similar to the one of the aerosols, which is related to marine biological activity. Marine bioaerosols are known to be efficient Ice Nucleating Particles (INPs). The emission of these INPs into the atmosphere from open waters would come on top of the temperature and sea ice fraction seasonalities as factors explaining the mixed-phase clouds monthly evolution.
Variability of temperature and ozone in the upper troposphere and
lower stratosphere from multi-satellite observations and reanalysis
data
Authors: Shangguan Ming , Wang Wuke , Jin Shuanggen
Published: December 2018

Abstract. Temperature and ozone changes in the upper troposphere and lower stratosphere (UTLS) are important components and sensitive indicators of climate change. In this paper, variability and trends of temperature and ozone in the UTLS were investigated for the period 2002–2017 using the high quality, high vertical resolution GPS RO data, improved merged satellite data sets (SWOOSH and C3S) and reanalysis data sets (including the newest ERA5, MERRA2 and ERA-Interim). All three reanalyses show good agreement with the GPS RO measurements in absolute values, annual cycle as well as interannual variabilities of temperature. However, relatively large biases exist for the period 2002–2006, which reveals an evident discontinuity of temperature time series in reanalyses. Based on the multiple linear regression methods, a significant warming of 0.2–0.3 K/decade is found in most areas of the troposphere with stronger increase of 0.4–0.5 K/decade in mid-latitudes of both hemispheres. In contrast, the stratospheric temperature decreases at a rate of 0.1–0.3 K/decade except that in the lower most stratosphere (100–50 hPa) in the tropics and parts of mid-latitude in the Northern Hemisphere (NH). ERA5 shows improved quality compared with ERA-Interim and performs the best agreement with the GPS RO data for the recent trends of temperature. Similar with temperature, reanalyses ozone are also affected by the change of assimilated observations and methods. Negative trends of ozone are found in NH at 150–100 hPa while positive trends are evident in the tropical lower stratosphere. Asymmetric trends of ozone can be found for both hemispheres in the middle stratosphere, with significant ozone decrease in NH mid-latitudes and increase of ozone in the Southern Hemisphere (SH) mid-latitudes. According to model simulations, the temperature increase in the troposphere as well as ozone decrease in the NH stratosphere could be mainly connected to the increase of Sea Surface Temperature (SST) and subsequent changes of atmospheric circulations.

Published: December 2018

Abstract. The Regional Atmospheric Modeling System (RAMS) has been interfaced with the Maximum Likelihood Ensemble Filter (MLEF) with the goal of improving initial conditions for aerosol weather forecasting via atmosphere-aerosol coupled data assimilation (RAMS-MLEF). In order to assimilate satellite retrieved aerosol optical depth (AOD), an AOD observation operator customized for the RAMS aerosol module is implemented. Two MLEF-RAMS experiments are carried out for a dust storm event over the Arabian Peninsula that occurred on 4 August 2016. In the first experiment, conventional atmospheric observations from the National Centre for Environmental Prediction (NCEP) Prepared Binary Universal Form for the Representation of meteorological data (PrepBUFR) dataset are assimilated (ATMONLY), while both the atmospheric observations and AOD retrievals from Moderate Resolution Imaging Spectroradiometer (MODIS) are assimilated in the second experiment (ATMAOD). In the two experiments, a list of control variables is used and it includes the three-dimensional wind components, perturbation Exner function, ice-liquid water potential temperature, total water mass mixing ratio, and the two dust modes from the aerosol module. Results indicate that the assimilation of MODIS AOD retrievals improves the representation of the dust plume over Persian Gulf, however, has no obvious impact on the dust plume interior of Saudi Arabia. Such finding is further supported by the examination of analysis increments of some control variables and the information measure in terms of degrees of freedom for signal. This is likely due to the lack of AOD retrievals interior of the Arabian Peninsula. Finally, a 12-h forecast initialized from both experiments is conducted. In general, ATMAOD forecast better represents the Persian Plume but performs poorly for the Saudi Plume, when verified against the aerosol reanalysis product from the Modern-Era Retrospective Analysis for Research and Applications version 2 (MERRA-2) dataset.
Radiometric correction of observations from microwave humidity sounders
Authors: Moradi Isaac , Beauchamp James , Ferraro Ralph
Published: December 2018

Abstract. The Advanced Microwave Sounding Unit-B (AMSU-B) and Microwave Humidity
Sounder (MHS) are total power microwave radiometers operating at frequencies
near the water vapor absorption line at 183 GHz. The measurements of these
instruments are crucial for deriving a variety of climate and hydrological
products such as water vapor, precipitation, and ice cloud parameters.
However, these measurements are subject to several errors that can be
classified into radiometric and geometric errors. The aim of this study is to
quantify and correct the radiometric errors in these observations through
intercalibration. Since the bias in the calibration of microwave instruments
changes with scene temperature, a two-point intercalibration correction
scheme was developed based on averages of measurements over the tropical
oceans and nighttime polar regions. The intercalibration coefficients were
calculated on a monthly basis using measurements averaged over each specified
region and each orbit, then interpolated to estimate the daily coefficients.
Since AMSU-B and MHS channels operate at different frequencies and
polarizations, the measurements from the two instruments were not
intercalibrated. Because of the negligible diurnal cycle of both temperature
and humidity fields over the tropical oceans, the satellites with the most
stable time series of brightness temperatures over the tropical oceans
(NOAA-17 for AMSU-B and NOAA-18 for MHS) were
selected as the reference
satellites and other similar instruments were intercalibrated with respect to
the reference instrument. The results show that channels 1, 3, 4, and 5 of
AMSU-B on board NOAA-16 and channels 1 and 4 of AMSU-B on board NOAA-15 show
a large drift over the period of operation. The MHS measurements from
instruments on board NOAA-18, NOAA-19, and MetOp-A are generally consistent
with each other. Because of the lack of reference measurements, radiometric
correction of microwave instruments remain a challenge, as the
intercalibration of these instruments largely depends on the stability of the
reference instrument.
Characterization and application of artificial light sources for nighttime
aerosol optical depth retrievals using the VIIRS Day/Night Band
Authors: Zhang Jianglong , Jaker Shawn L. , Reid Jeffrey S. , Miller Steven D. , Solbrig Jeremy , Toth Travis D.
Published: December 2018

Abstract. Using nighttime observations from Visible/Infrared Imager/Radiometer Suite (VIIRS) Day/Night band (DNB), the characteristics of artificial light sources are evaluated as functions of observation conditions and incremental improvements are documented on nighttime aerosol retrievals using VIIRS DNB data on a regional scale. We find that the standard deviation of instantaneous radiance for a given artificial light source is strongly dependent upon the satellite viewing angle, but is weakly dependent on lunar fraction and lunar angle. Retrieval of nighttime aerosol optical thickness (AOT) based on the novel use of these artificial light sources is demonstrated for three selected regions (United States, Middle East, and India) during 2015. Reasonable agreements are found between nighttime AOTs from VIIRS DNB and temporally adjacent daytime AOTs from AErosol RObotic NETwork (AERONET) as well as from coincident nighttime AOT retrievals from the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP), indicating the potential of this method to begin filling critical gaps in diurnal AOT information at both regional and global scales. Issues related to cloud, snow, and ice contamination during the winter season, as well as data loss due to the misclassification of thick aerosol plumes as clouds, must be addressed to make the algorithm operationally robust.
Including the efficacy of land ice changes in deriving climate
sensitivity from paleodata
Authors: Stap Lennert B. , Köhler Peter , Lohmann Gerrit
Published: December 2018

Abstract. The influence of long-term processes in the climate system, such as land ice changes, has to be compensated for when comparing climate sensitivity derived from paleodata with equilibrium climate sensitivity (ECS) calculated by climate models, which is only generated by a CO2 change. Several recent studies found that the impact these long-term processes have on global temperature cannot be quantified directly through the global radiative forcing they induce. This renders the approach of deconvoluting paleotemperatures through a partitioning based on radiative forcings inaccurate. Here, we therefore implement an efficacy factor ε[LI], that relates the impact of land ice changes on global temperature to that of CO2 changes, in our calculation of climate sensitivity from paleodata. We apply our new approach to a proxy-inferred paleoclimate dataset, and find an equivalent ECS of 5.6 ± 1.3 K per CO2 doubling. The substantial uncertainty herein is generated by the range in ε[LI] we use, which is based on a multi-model assemblage of simulated relative influences of land ice changes on the Last Glacial Maximum (LGM) temperature anomaly (46 ± 14 %). The low end of our ECS estimate, which concurs with estimates from other approaches, tallies with a large influence for land ice changes. To separately assess this influence, we analyse output of the PMIP3 climate model intercomparison project. From this data, we infer a functional intermodel relation between global and high-latitude temperature changes at the LGM with respect to the pre-industrial climate, and the temperature anomaly caused by a CO2 change. Applying this relation to our dataset, we find a considerable 64 % influence for land ice changes on the LGM temperature anomaly. This is even higher than the range used before, and leads to an equivalent ECS of 3.8 K per CO2 doubling. Together, our results suggest that land ice changes play a key role in the variability of Late Pleistocene temperatures.
A review of methods for measuring groundwater–surface water exchange in braided rivers
Authors: Coluccio Katie , Morgan Leanne Kaye
Published: December 2018

Abstract. Braided rivers, while uncommon internationally, are significant in terms of their unique ecosystems and as vital freshwater resources at locations where they occur. With an increasing awareness of the connected nature of surface water and groundwater, there have been many studies examining groundwater–surface water exchange in various types of waterbodies, but significantly less research has been conducted in braided rivers. Thus, there is currently limited understanding of how characteristics unique to braided rivers, such as channel shifting; expanding and narrowing margins; and a high degree of heterogeneity affect groundwater–surface water flow paths. This article provides an overview of characteristics specific to braided rivers, including a map showing the regions where braided rivers are concentrated at the global scale: Alaska, Canada, the Japanese and European Alps, the Himalayas and New Zealand. To the authors' knowledge, this is the first map of its kind. This is followed by a review of prior studies that have investigated groundwater-surface water interactions in braided rivers and their associated aquifers. The various methods used to characterise these processes are discussed with emphasis on their effectiveness in achieving the studies' objectives and their applicability in braided rivers. The aim is to provide guidance on methodologies most suitable for future work in braided rivers. In many cases, previous studies found a multi-method approach useful to produce more robust results and compare data collected at various scales. Ultimately, the most appropriate method(s) for a given study will be based on several factors, including the scale of interactions that need to be observed; site-specific characteristics; budget; and time available. Given these considerations, we conclude that it is best to begin braided river studies with broad-scale methods such as airborne thermal imaging, differential flow gauging or tracer analysis and then focus the investigation using finer scale techniques such as groundwater well observations or temperature sensors. Given the challenges of working directly in braided rivers, there is considerable scope for the increased use of remote sensing techniques and geophysics. There is also opportunity for new approaches to modelling braided rivers using integrated techniques that incorporate the often-complex river bed terrain and geomorphology of braided rivers explicitly. We also identify a critical need to improve understanding of the role of hyporheic exchange in braided rivers; rates of recharge to/from braided rivers; and historical patterns of dry and low-flow periods in these rivers.

Las crónicas del viaje por la Península Ibérica de Cosimo III de’ Medici: clasificación de fuentes y autores
Authors: Neira Cruz Xosé Antonio
Published: December 2018

Cosimo III de’ Medici (1642-1723), gran duque de Toscana entre 1670 y 1723, ha pasado a la historia como uno de los grandes viajeros de su momento, también uno de los monarcas más versados en cuestiones relacionadas con la geografía, la cartografía, la botánica y el conocimiento de contenidos que actualmente calificaríamos como interculturales, virtudes estas que, sin embargo, han quedado empañadas por la negativa valoración histórica de Cosimo III como gobernante. Cuando todavía era príncipe heredero, Cosimo de’ Medici acometió una serie de viajes de larga duración que comenzaron en 1667 y se prolongaron, con breves intervalos de estancia en Florencia, hasta el 1 de noviembre de 1669, fecha de su definitivo regreso. El periplo por la Península ibérica se extendió desde el 25 de septiembre de 1668 (fecha de la llegada de la comitiva a Cadaqués) hasta el 19 de marzo de 1669, cuando zarparon desde Coruña rumbo a Inglaterra. En este artículo nos ocuparemos de la clasificación de la totalidad de las fuentes conocidas del viaje de Cosimo de’ Medici por España y Portugal, trabajo este nunca acometido hasta el momento de forma exhaustiva y comparada, así como de la identificación sus autores expresos o atribuidos.
Recepción contemporánea de lo homérico en el Séptimo Arte: los filmes de Guy Maddin y Attieh y Garcia como tangencias mitológicas
Authors: García Manso Angélica , Tovar Paz Francisco J.
Published: December 2018

Se analizan los filmes Keyhole (2011), de Guy Maddin, y H. (2014), de Rania Attieh y Daniel Garcia, desde la perspectiva del Myth Criticism, a partir de los motivos homéricos presentes en sendas producciones. Una concepción diferente del tiempo (en forma de bucle y de abducción respectivamente) y la perspectiva tangencial en los relatos mitológicos (enfocados desde el punto vista de Telémaco y Helena de Troya en una y otra películas y no desde sus protagonistas primordiales) constituyen dos de los elementos del enfoque irónico que la contemporaneidad hace de los temas de la épica homérica.
Escritura sobre la imagen: El caso crítico de "Monje frente al mar" de Caspar David Friedrich
Authors: García Vázquez Milagros
Published: December 2018

En este artículo se presenta el análisis de una de las críticas coetáneas realizadas a la pintura Monje frente al mar (1810) de Caspar David Friedrich. Se trata de “Empfindugen vor Friedrichs Seelandschaft”, escritas por Clemens Brentano junto a Achim von Arnim, modificadas y publicadas en Berliner Abendbläter por Heinrich von Kleist. Los objetivos son, por un lado, encontrar y exponer una relación entre este ejercicio crítico-dramático con la crítica posterior sobre la obra y cómo es vinculada en ella Monje frente al mar con el arte contemporáneo; y por otro, plantear un nexo entre la forma dramatizada de esta crítica de arte y las novedades formales y semánticas presentes en el lienzo del pintor alemán.
Digital technology, a real motor of project-based learning in scientific and technical French
Authors: Olmo Cazevieille Françoise
Published: December 2018

Nowadays, digital technologies lie at the heart of university syllabus, which want to provide an answer to current social demands. Likewise, digital technologies are key in nowadays teaching practices that use them as essential tools in the deployment of an active pedagogy where students have become the protagonists of the learning process. However, the question that arises is not about their use but rather about how to integrate them into classroom activities. In other words, which activities are relevant to transform the use of digital technology into a real motor? Simple access to online resources is surely not enough. Their use must transform everyday class content and change our relationship with the teaching-learning process, how we act, and how we teach students. In this vein, project-based pedagogy is a way to achieve this and to give our students the necessary boost to go further in their learning process. This is, in a word, the aim of this paper.
El viaje y su ilustración: la función de la imagen en los relatos franceses de viajes (siglos XVI-XIX)
Authors: G. de Uriarte Marrón Cristina
Published: December 2018

El abundante material iconográfico que genera la literatura de viajes no solo constituye un complemento de la parte escrita, sino que cumple, también, una innegable función estética. A partir de ejemplos representativos de una quincena de relatos de viajes franceses, que comprenden un periodo que abarca los siglos XVI-XIX, nos proponemos reflexionar acerca de la función de la imagen y su evolución en dichas obras. En un primer momento nos centraremos en la representación, real y fabulada, de lugares y personas; seguidamente, abordaremos la ilustración científica y el paisaje para concluir con algunas precisiones sobre las imágenes en este género literario.
L’image leclézienne, icône d’identité et de mémoire
Authors: Pagán López Antonia
Published: December 2018

L’image leclézienne, virtuelle ou réelle, est souvent intercalée dans le tissu narratif, conférant une profondeur à l’écriture. La figure du photographe, porté sur des adolescentes aux traits ethniques, sans repères identitaires, est introduite dans ses récits. La photographie, de par son caractère visuel, fixe le souvenir et devient une icône d’identité, impuissante, pourtant, à restituer les lacunes de la mémoire. L’écriture, comme la photo, fige l’instantanéité du vécu, la puissance des mots étant, parfois, plus efficace à retranscrire le passé. De même que l’image, l’écriture est support d’identité et projection d’une mémoire ancienne qui remonte à un état de pré-conscience avant l’existence du narrateur. La lumière, clé de voûte de l’image photographique ou cinématographique, et l’onirisme de l’image filmique sont porteurs d’un langage métaphorique des figures de la déliquescence. Malgré la constante imbrication image-mémoire les héros lecléziens, enfouis dans les sables mouvants du souvenir, sont lancés à la poursuite d’une identité comblée.

Published: December 2018

HIV post-exposure prophylaxis (PEP) prescriptions are not uniformly monitored in the United States. We developed a method to identify PEP-related visits in New York City emergency departments (EDs). Using ED data, we observed a threefold increase in PEP-related visits to NYC EDs from 2002-2013. 73% of PEP-related visits were among males, and 45% among adults ages 25-34 years. Incorporation of this method of PEP monitoring in the NYC syndromic surveillance system will be used to observe trends and inform HIV outreach efforts.

O estudo analisa a implantação, o planejamento e monitoramento do Núcleo de Apoio à Saúde da Família (NASF). Fundamenta-se nos dados da avaliação externa do segundo ciclo do PMAQ-AB,  agrupados segundo a classificação dos perfis de município proposta pelo IBGE, sendo a amostra composta por 18.930 equipes de saúde. A composição das equipes de apoio apresentou-se insatisfatória para a AB, contudo o planejamento conjunto das ações mostrou-se frequente, principalmente em regiões metropolitanas. A maioria das equipes revelou avaliar-se apenas através da autoavaliação do programa. O NASF foi implantado sem a devida articulação com a AB, centralizado na gestão, principalmente nas capitais, onde, entretanto, planejou suas ações de forma mais sistemática. Tal planejamento mostrou-se organizado, periódico e articulado, porém com mecanismos compensatórios por parte dos NASF nos perfis caracterizados pela vulnerabilidade socioeconômica. O monitoramento ainda é uma atividade subexplorada em todo o país, exceto quando induzidas pelo incentivo financeiro proporcional à nota das equipes participantes do programa.
A Possible Glimpse at the Role of Naturally-Occurring Radiation as a Contributing Factor to Genetic Variance among Populations of Living Organisms
Authors: Rodriguez Tommy
Published: December 2018

A fundamental question in evolutionary biology is understanding why some groups of organisms are highly diverse. Species diversity is the result of the balance between speciation and extinction whereas morphological disparity is primarily a consequence of adaptation. Radioresitance, among other adaptive features found in organisms, can be genetically determined and inherited. This study explores the possible consequences that naturally-occurring radiation might impose on the variance and composition of population genetics. To evaluate these possibilities, a simple statistical experiment is conducted involving 49 cytochrome gene sequences belonging to two distinct populations of eukaryotic organisms that reside on opposite ends of the radioresistance spectrum. The results show a distinct correlation between higher and lower degrees of genetic variance among these two groups, where the order, group or population that has shown increased hypersensitivity to radiation also has an increased rate of molecular evolution due to a higher mutation rate.

Mecanismos de regeneração natural são fundamentais para o restabelecimento das funções ecológicas de fragmentos florestais e de áreas degradadas. O presente trabalho teve como objetivo avaliar a chuva de sementes e o estabelecimento de plântulas de espécies arbóreas em Floresta Atlântica, localizada na região Nordeste do Brasil. Para amostragem da chuva de sementes foram alocados 60 coletores (área de 0,196 m²), ficando equidistantes, aproximadamente, de 50 m. As coletas foram realizadas com intervalo de 30 dias por um período de 12 meses. Para avaliar o estabelecimento de plântulas foram alocadas subparcelas ao lado dos coletores, totalizando 60 subparcelas de 0,25 m² cada. Os indivíduos arbóreos identificados pelos diásporos coletados na chuva de sementes e pelas plântulas estabelecidas no fragmento foram contados e classificados quanto à síndrome de dispersão e grupo sucessional. A chuva de sementes foi representada por 60 morfoespécies e 20 famílias botânicas. O grupo ecológico e a síndrome de dispersão predominante foram de espécies secundárias iniciais e zoocórica, respectivamente. Em relação às plântulas estabelecidas foram contadas 122 plântulas, sendo Tapirira guianensis L. com maior número de plântulas. A chuva de sementes apresenta potencial para manutenção da dinâmica florestal por apresentar alta riqueza de espécies que compõe a atual vegetação, sendo composta, predominantemente, por espécies que produzem frutos abundantes com dispersão zoocórica que servem de alimento para fauna. Enquanto poucas sementes germinam para formar o banco de plântulas, a maioria está contribuindo para formação do banco de sementes.

Este estudo analisa relações existentes entre o incremento médio anual em diâmetro e variáveis biométricas, morfométricas e ambientais em uma floresta nativa de Araucaria angustifolia no município de Lages-SC. Foram utilizados dados dendrocronológicos obtidos de 121 árvores dominantes e competidoras. Os indivíduos foram separados em 3 classes diamétricas, abrangendo indivíduos com DAP de 10 cm a 29,9 cm (C1), entre 30 e 49,9 cm (C2) e acima de 50 cm de DAP (C3). O banco de dados foi formado por uma matriz com as 121 árvores e 23 variáveis do ambiente, dendrométricas e morfométricas, que incluiu direcionamento de fluxo, acúmulo de fluxo, radiação solar, face de insolação, declividade, altitude, incremento médio em diâmetro, diâmetro, altura, distância (dominante/competidor), raios de copa por direção geográfica, área basal, idade, raio médio de copa, diâmetro de copa, área de copa, incremento em diâmetro por direção geográfica. Sendo que estas variáveis foram obtidas por meio dos algoritmos a partir do Modelo Digital de Elevação da área. As relações foram interpretadas com base nos resultados da análise multivariada, fazendo uso da análise de Cluster, análise fatorial e análise de componentes principais. As árvores apresentavam diâmetros variando entre 10 e 87,6 cm e alturas entre 5,3 e 21 m, com incremento médio anual em diâmetro de 0,708 cm, com média para 40 anos em análise retrospectiva. Constatou-se distinção de dois grupos e seis fatores diferenciados, que explicaram 81,5% da variância, sendo formados pelas características morfométricas e biométricas e pelas relações do incremento com as variáveis ambientais. As técnicas de análise multivariada podem ser aplicadas para auxílio na tomada de decisão no manejo florestal, pois comprovaram a correlação entre o incremento médio em diâmetro (essencial para compor o ciclo de corte florestal) e sua relação aos fatores do ambiente, índices de forma, espaço e dimensão dos indivíduos.

Se analizó la productividad de segundos y terceros raleos en plantaciones de Pinus taeda y Pinus elliottii var. elliottii x Pinus caribaea var. hondurensis realizados con harvesters de ruedas en el Noreste Argentino. Los árboles cosechados en los segundos raleos presentaron un volumen medio de 0,43 m³ para Pinus taeda de 12 años y 0,36 m³ para pino hibrido de 10 años, mientras que en los terceros raleos este valor fue de 0,71 m³ para Pinus taeda de 13 años y 0,75 m³ para pino hibrido de 15 años respectivamente. Se desarrollaron modelos de tiempos parciales para cada una de las actividades que componen el ciclo operacional y se determinó la influencia del tipo de raleo, especie cosechada, número de productos elaborados, volumen de los árboles y forma de volteo, sobre el tiempo insumido por cada actividad. Los modelos ajustados fueron integrados en un modelo de productividad efectiva consiguiéndose un coeficiente de determinación ajustado R2 Aj de 0,61. El volumen de los árboles resultó significativo para explicar la duración de todas las actividades evaluadas, siendo especialmente determinante en el volteo de los árboles, su desrame y trozado. El tipo de raleo afectó al tiempo de ubicación, mientras que la especie afectó al tiempo de desrame y trozado. La elaboración de hasta tres productos diferentes requirió un mayor tiempo destinado al desrame y trozado. Ocurrió un aumento de la cantidad de productos cuando se realizaron terceros raleos sobre pino hibrido, respecto Pinus taeda.

De modo a determinar o potencial energético dos combustíveis florestais em cultivos de Pinus elliottii, foi analisada a melhor época de coleta deste material em função da umidade, disponibilidade, Poder Calorífico Superior (PCS) e composição química imediata, em parcelas estabelecidas e monitoradas durante um ano na estação experimental de Rio Negro, estado do Paraná. No delineamento experimental, as estações do ano (inverno, verão, primavera e outono) foram consideradas blocos, enquanto as seguintes classes de diâmetro do material combustível os tratamentos: AA, na camada superior; AB, na camada intermediária; AC, na camada inferior, todas com material de diâmetro até 0,7 cm; e a B, com material de 0,71 a 2,5 cm. No campo, foi determinada a massa (base úmida) do material coletado nas subparcelas de 900 cm2 e posteriormente levadas ao laboratório da Universidade Federal do Paraná (UFPR), no qual se procederam as análises referentes à umidade (base seca), Poder Calorífico Superior (PCS) e composição química imediata. Foi recorrido à análise de variância (ANOVA) e ao Teste de Tukey para comparação das épocas (blocos) e das diferentes classes de material combustível (tratamentos). Com baixo teor de umidade e maior quantidade de material disponível, observou-se pelo teste de médias, para todas as classes de material, que o inverno foi a melhor época de coleta. Para a mesma época de coleta foi possível observar pelo PCS e análise da composição química imediata que as médias das classes AA e B foram estatisticamente superiores em relação às demais. A manta apresentou densidade energética considerável (12.275,42.105 kcal.ha-1) para conversão em bioenergia. Pelos resultados do presente estudo observou-se que existe potencial para aproveitamento de resíduos florestais como fonte de energia limpa e renovável
CARACTERIZAÇÃO MORFOLÓGICA E ESTRUTURAL DE FIBRAS NA COLMO DO BAMBU DENTRO DE COLMO – Guadua angustifolia KUNTH

Published: December 2018

O estudo sobre os materiais para obter fibras naturais tem tido grande importância nas últimas décadas devido às características excepcionais que essas fibras oferecem, as quais as convertem em uma alternativa interessante para substituir as fibras sintéticas em diferentes aplicações. O Bambu tem alta disponibilidade em várias regiões do mundo, devido à capacidade de adaptação e de crescimento em diferentes áreas. Apesar de as fibras de bambu estarem sendo altamente aplicadas, sua organização microestrutural dentro das hastes não tem sido estudada amplamente. O objetivo desta pesquisa está baseado no desenvolvimento e estudo das características e distribuição das fibras dentro do colmo no bambu nativo colombiano Guadua angustifolia Kunth. Neste estudo foram consideradas duas variedades de Guadua: Guadua angustifolia Kunth Rayada Amarilla e Guadua angustifolia Kunth Macana. As Guaduas foram analisadas por microscopia eletrônica de varredura, esta técnica é usada para observar a morfologia da fibra de Guadua e a sua variação através do colmo. Difração de raios X é usada para observar variação dos compostos através do colmo. Finalmente, a metodologia da “Association Official Agricultural Chemist – 2000” (AOAC-2000) é usada para obter informação quantitativa do conteúdo de fibra não solúvel. Os resultados indicaram que a distribuição de fibras não solúveis não é homogênea entre as camadas internas e externas da haste do bambu, isso aumenta na direção radial da parede interna até a parede externa; os padrões de difração de raios X mostram que a celulose presente no colmo tem uma preferência de ligação cristalina relacionada à direção do crescimento da planta. A combinação da análise de microscopia eletrônica de varredura e a difração de raios X oferecem informações importantes sobre a distribuição e a morfologia dentro do colmo dos componentes do Bambu.

Published: December 2018

Este texto tem como objetivo discutir a experiência realizada no estágio com o Ensino Médio, em uma escola pública estadual, durante o curso de Educação Física, Licenciatura. A proposta metodológica foi sustentada na perspectiva crítico-emancipatória. Um dos temas da cultura corporal trabalhado foi o funk. Nas quatro aulas ministradas, analisamos imagens, músicas e vídeos referentes ao funk. A experiência evidenciou que o debate sobre o funk na escola é relevante para os estudantes, pois, ao problematizarem letras, imagens e gestualidades, ampliaram a compreensão relativa a aspectos históricos, culturais e sociais que o constituem como manifestação da cultura popular.

O presente texto tem como objetivo desvelar questões em relação às práticas corporais e os entendimentos de corpo que têm frequentadores de uma praia na orla da cidade de Vitória/ES. Foi desenvolvida uma pesquisa qualitativa baseada na produção etnográfica. Também foram utilizadas entrevistas dirigidas semiestruturadas das quais se criaram os diferentes eixos de análise. Dentre os principais resultados destacamos como os frequentadores do espaço constroem diferentes entendimentos em torno de um discurso baseado no bem-estar, para assim justificar e construir suas próprias noções de saúde, estética e corpo.
Educação Física aberta à experiência: um diálogo com as cinco teses de Hildebrandt-Stramann (2009)
Authors: Castro Felipe Barroso de
Published: December 2018

Nesse ensaio, apresento o tema da experiência relacionado ao ensino nas aulas de Educação Física sob a perspectiva do “se-movimentar”. Para isso proponho um diálogo com as cinco teses de Hildebrandt-Stramann (2009) para uma Educação Física aberta à experiência. Acredito que as teses propostas pelo autor apontam para a importância e a necessidade de exploração de experiências corporais na escola frente a um aparente “empobrecimento” do mundo de movimentos de crianças, consequência de fatores como a exposição precoce, sem o devido cuidado, as novas tecnologias o que, por vezes, as afasta do brincar e das experiências sensíveis.
Pedro Manuel Colón de Portugal, duque de Veragua. Un Consejero de Estado de Carlos II en un territorio en disputa = Pedro Manuel Colón de Portugal, Duke of Veragua. A State Councillor of Charles II os Spain in a Disputed Territory
Authors: Martínez López Rocío

Pedro Manuel Colón de Portugal, duque de Veragua, fue uno de los consejeros de Estado designados por Carlos II en noviembre de 1699. En el momento de su nombramiento, desempeñaba el cargo de virrey de Sicilia, por lo que su influencia en las consultas al Consejo de Estado en las que se debatió la cuestión sucesoria fue limitada. En el presente artículo, se pretende estudiar la figura de don Pedro Manuel Colón de Portugal centrándonos en tres aspectos principales: las razones que llevaron a su nombramiento como Consejero de Estado en una coyuntura especialmente difícil para la Monarquía de España, la influencia que tuvo en la problemática sucesoria y, a través de su desempeño como virrey de Sicilia, cómo el gobierno de Madrid afrontó la incertidumbre de la sucesión de Carlos II en distintos territorios de Italia y su respuesta ante la amenaza que suponían los tratados de reparto.Pedro Manuel Colón de Portugal, duke of Veragua, was one of the State Councilors appointed by king Charles II of Spain in November, 1699. When he was designated as such, he was already viceroy of Sicily, which is why his influence in those inquiries to the Counsel of State related to the debate of the problem of Charles II’s succession was very limited. In this article, we aim to study the figure of don Pedro Manuel Colón de Portugal, focusing on three key points: the reasons why he was appointed to the State Council in a moment especially difficult for the Spanish Monarchy, the influence he had in the problem of Charles II’s succession and, in his capacity as viceroy of Sicily, how the different territories of Italy faced the problem of the king’s succession and their answer to the threat the Partition Treaties posed for their future.
La parábola del príncipe de Vaudémont entre austracismos y provechos personales
Authors: Cremonini Cinzia
Published: December 2018

Nacido en Bruselas el 17 de abril de 1649 (o en el 1642), Carlos Enrique de Lorena, príncipe de Vaudémont era hijo del duque de Lorena Carlos IV (1604-1675) y de su segunda mujer, Beatriz de Cusance. De la boda de Carlos Enrique con Ana Isabel de Lorena-Elboeuf (1649-1714), naciò Carlos Tomás (1670-1704), que fue encaminado a la carrera militar en los rangos imperiales. En lo años Ochenta y Noventa Carlos Enrique servió a los Habsburgo de España en Flandes: condecorado por la prestigiosa Orden del Toisón de Oro, tomó el cargo de capitán general de la caballería del ejército español en Flandes. Fue con su mujer a Italia en la primavera del 1690 y del 1692. En la Guerra de la Liga de Augusta fue entroducido en las esferas de dependencias de Guillermo de Orange (1650-1702), que fue su principal protección junto con el potente conde de Melgar, último Almirante de Castilla, político muy influyente que le procurò algunos cargos de gobierno en los territorios de la Monarquía. Se debe considerar estos dos importantes patronazgos las principales fuentes de su promoción en el Consejo de Estado el 29 noviembre de 1699 entre los projectos del partido austracista porlo que se refiere al tema de la successión a Carlos II. El Vaudémont no pudo nunca participar a las consultas porque fue gobernador de Milàn entre 1698 y 1706. Murió a Commercy en el 1723.  Born in Brussels on 17 April 1649 (or 1642), Charles Henry of Lorraine, prince of Vaudemont was the son of Charles IV, duke of Lorraine (1604-75) and his second wife, Beatrice de Cusance. Charles Henry’s first marriage, to Anne Elisabeth of Lorrsaine – Elboeuf (1649-1714) produced Charles Thomas (1670-1704), who was destined for a military career in the Imperial armies. In the 1680s and 1690s Charles Henry served the Spanish Habsburgs in Flanders: awarded the prestigious Order of the Golden Fleece, he held the post of captain general of the Spanish cavalry in Flanders. He went with his wife to Italy in the spring of 1690 and again in 1692. During the War of the League of Augsburg he was introduced into the patronage network of William of Orange (1650-1702), who was his chief protector, along with the powerful count of Melgar, the last Admiral of Castile, a very influential politician who obtained for him various senior government posts in the territories of the Monarchy. To these two important patrons must be attributed his promotion to the Council of State on 29 November 1699. However, Vaudemont could never take part in the consultas of the council because he was governor of Milan between 1698 sand 1716. He died at Commercy in 1723.
A Distant Council, Nearby Problems. The Duke of Medinaceli, Naples, and the Unity of the Spanish Monarchy, 1696-1702 = Consejo lejano, problemas cercanos. El duque de Medinaceli, Nápoles y la unidad de la Monarquía Hispánica, 1696-1702

This paper analyzes the role of the duke of Medinaceli in face of the Spanish succession crisis. By rejecting historiographical attempts to include the duke within one or other dynastic party, the essay emphasizes instead his total loyalty to the united Spanish Monarchy. By doing so, the defense of the unity of the Monarchy attempted by Medinaceli is understood not only in a territorial viewpoint but as a safeguard of a distinctive political model: the so-called ‘aristomanzia’. Thanks to it, Spanish nobility had been traditionally able to control the King by way of the Council of State and the consensus of the Grandees, a practice threatened at the beginning of the Eighteenth Century and defended, but without success, by Medinaceli.This paper analyzes the role of the Duke of Medinaceli in the face of the Spanish succession crisis.
