Authors: Marjit Ujjal , Sarkar Arup , Santra Subhrangsu , Biswas Utpal
Published: November 2020

Automated service discovery is one of the very important features in any Semantic Web Service (SWS) based framework. Achieving this functionality in e-resource sharing system is not an easy task due to its hugeness and heterogeneity among the available resources. Any efficient automated service discovery will remain worthless until discovered services fulfill the required goal(s) demanded by the user or the client program. In this paper we have proposed a goal driven approach towards an automated service discovery using Agent Swarm in an innovative way .A novel multi agent based architecture has been introduced here for service discovery. Communications among the agent in service-oriented framework for the said purpose has also been illustrated here. Finally, the pictorial view of the running agent in the system is shown.
Variation and Correlation between the Physical Properties of Dogwood Seeds
Authors: KALINIEWICZ Zdzisław
Published: November 2020

Information about the physical properties of berries of selected dogwood species is available in the literature, but the basic physical traits of berry seeds have not been investigated to date. In this study, the terminal velocity, thickness, width, length, angle of external friction and mass of seeds of 11 dogwood species were measured. The measured parameters were used to calculate the geometric mean diameter, aspect ratio and sphericity index of each seed. The average values of the evaluated parameters were determined in the following range: terminal velocity - from 9.95 to 13.15 m s-1, thickness - from 3.31 to 5.02 mm, width - from 4.14 to 5.38 mm, length - from 4.33 to 11.55 mm, angle of external friction - from 9.97 to 29.85 ºC, mass - from 33.06 to 175.51 mg. The analyzed dogwood species were arranged in the following ascending order based on the geometric mean diameter of their seeds: Cornus macrophylla, Cornus alba, Cornus amonum, Cornus kousa, Cornus obliqua, Cornus controversa, Cornus walteri, Cornus sanguinea, Cornus florida, Cornus officinalis and Cornus mas. The seeds of Cornus alba, Cornus controversa, Cornus florida, Cornus kousa, Cornus macrophylla, Cornus mas and Cornus officinalis could be sorted with the use of mesh sieves with longitudinal openings, the seeds of Cornus macrophylla, Cornus sanguinea and Cornus walteri - with the use of mesh sieves with round openings, and the seeds of Cornus alba, Cornus macrophylla and Cornus obliqua - with the use of cylindrical graders.

Authors: SUTTHIPHATKUL Tanyarat , SUWANPOSRI Amornrat , OCHAIKUL Duangjai
Published: November 2020

Bacterial Cellulose (BC) production from Fermented Rice Noodle Wastewater (FRNW) was fermented by Komagataeibacter sp. PAP1. In order to increase the production of BC, the FRNW-based medium was prepared and optimized for the cultivation of this bacterium. The optimized FRNW-based medium was composed of 5 % (w/v) mannitol, 0.1 % (w/v) beef extract, 0.5 % (v/v) ethanol, 1 % (v/v) acetic acid, pH 7.0 which were incubated at 30 °C for 10 days. Under these conditions, BC yielded 11.76 ± 0.34 g/L higher (4.40 fold) than the standard Hestrin-Schramm (HS) medium. The study on growth and BC production by Komagataeibacter sp. PAP1 in optimized culture condition showed that BC production by Komagataeibacter sp. PAP1 was growth-associated. The bacterial cell of Komagataeibacter sp. PAP1 increased exponentially from the 3rd to 5th day. The BC paper sheets produced using the obtained BC pellicle from an optimized FRNW-based medium gave higher mechanical strength than those from standard HS medium. This study reveals the use of FRNW as a substrate for BC production. The results indicated that FRNW, which is more environmentally friendly, can be used as an alternative low-cost substrate for BC production.
CAMINHOS QUE SE INTERCRUZAM ENTRE A EDUCAÇÃO DO CAMPO E A EDUCAÇÃO DE JOVENS E ADULTOS: MARCAS DA EDUCAÇÃO POPULAR
Authors: Castro Liliane Borba , Cunha Júnior Adenilson Souza
Published: November 2020

Este artigo objetiva, através de uma revisão de literatura, realizar uma análise sobre a importância da educação no processo de desenvolvimento humano, levando em consideração o contexto da Educação Popular para a formação da Educação do Campo e da Educação de Jovens e Adultos (EJA). Nessa abordagem, a relação histórico-social entre campo, sujeitos e movimentos sociais foi apresentada tendo como enfoque a Educação do Campo, observando sua articulação com a Educação Popular num projeto de educação emancipatória. Na reflexão acerca da relação existente entre Educação Popular e Educação de Jovens e Adultos, a análise demandou o reconhecimento da EJA enquanto representação popular e também como modalidade de ensino, trazendo como referência sua identidade de luta frente à conquista de direitos. As discussões evidenciam que os interesses capitalistas interferem diretamente na sociabilidade humana, impondo um modo de existência e sobrevivência que muitas vezes desconfiguram a pessoalidade e as características peculiares a um determinado contexto social ou regional, configurando-se num processo de negação ou privação de direitos educacionais.

LA EDUCACIÓN POPULAR EN LOS ESTADOS UNIDOS: LAS HUELLAS DE PAULO FREIRE Y MYLES HORTON
Authors: Elisalde Roberto
Published: November 2020

El presente trabajo esta situado en el campo de la historia y la educación. Buscareconstruir uno de los procesos menos transitados por la tradición de la educación popularlatinoamericana, y norteamericana. En este caso rescatar vínculos, similitudes, encuentros ydiferencias de dos concepciones y referentes de la educación popular: Paulo Freire y MylesHorton. Freire durante su largo exilio de los años 60 y 70 fue invitado en reiteradas oportunidades a los Estados Unidos. Allí llevo a cabo intercambios en los que expuso y debatió con pares norteamericanos acerca de las posibilidades de interpretar y “aplicar” las ideas de “Pedagogía del oprimido “en territorios del primer mundo”. Harvard, Massachusetts, Tennessee, Los Ángeles fueron las principales estadías de Freire. En algunos casos con breves recorridos y en otros, con la meta de retornar para completar trabajos comunes. Así sucedió con el histórico educador popular norteamericano Myles Horton, creador de uno de los movimientos más relevantes en la historia de la educación popular de los EEUU, el Centro Highlander de Teennesse. Era corriente que a tanto a Horton como a Freire en sus presentaciones los participantes, indistinatmente, le preguntaran: “¿es posible pensar la educación popular en los Estados Unidos?” ¿Los países del Primer mundo pueden implementar estrategias de “tradición popular” en sus organizaciones y en sus aulas? Precisamente estas inquietudes, y sobre todo, la reconstrucción histórica de estos encuentrosserán el eje central de este trabajo.
Reconstrucción del desaparecido claustro renacentista de Santa María de Monfero
Authors: Lorenzo Aspres Alberta
Published: November 2020

Del actual claustro de la hospedería de Santa María de Monfero (A Coruña) tan sólo podemos observar el lienzo meridional, comenzado a construir a finales del siglo XVIII como substitución de un claustro anterior renacentista del que resta poco más que las ménsulas inscritas en los muros de los corredores y las dos esquinas del lienzo sur.

Con la intención de comprender y averiguar la realidad material de esta fábrica desaparecida y llevar a cabo la reconstrucción gráfica de la misma, aplicamos una metodología de recreación desarrollada desde el punto de vista de un triple análisis, consistente en el examen e interpretación de los documentos históricos, de la tipología claustral coetánea y de los vestigios heredados.
L’Objet Trouvé come modello tra approcci analogici e digitali
Authors: Colonnese Fabio
Published: November 2020

Sebbene questa stagione di tecnologie digitali e tecniche di produzione semiautomatica ha condizionato la maggior parte della tradizionale catena di montaggio e gli strumenti del processo di progettazione e rappresentazione, l'uso di found-objects nella modellistica è ancora praticato, rivelato e promosso da architetti e docenti contemporanei. Questo potrebbe essere interpretato come il sintomo di una sorta di resistenza analogica o un modo per introdurre incidenti pianificati e incertezza in un processo di progettazione deterministico e omologante, ma lo scenario è sfaccettato. Questo contributo discute l'uso di found-objects come modelli nella progettazione dell'architettura e nella pratica della comunicazione. In particolare, descrive le loro radici storiche e la loro funzione critica nella ricerca delle avanguardie artistiche, classifica il loro ruolo nelle diverse fasi del processo di progettazione tradizionale e contemporaneo e si concentra su interazioni e differenze degli approcci analogici e digitali, in relazione alle opportunità semantiche della rappresentazione architettonica.
Intensidad constructiva y visual en la obra inicial de Fargas y Tous (1954-1963)
Authors: Deulofeu Fuller Glenn Andrés
Published: November 2020

Las obras que Josep María Fargas y Enric Tous realizaron entre 1954 y 1963 constituyeron una particular manera de concebir la arquitectura moderna en España. Los limitados medios constructivos disponibles en el mercado de aquel entonces fomentaron en los arquitectos una intensa búsqueda de nuevas soluciones constructivas, evaluando rigurosamente en ellas no solo sus cuestiones técnicas, sino que también la manera en que estas se manifestaban visualmente. Esta predominante condición visual de las primeras obras de Fargas y Tous ha podido ser analizada por medio de un proceso de reconstrucción digital tridimensional de cuatro de las obras más representativas de este período. La intelección visual propiciada por el método ha sido plasmada en una secuencia de imágenes y texto. Con esto se espera poner en valor a un grupo de obras que, si bien ya no existen físicamente, se mantienen aún vigentes en muchos de sus principios arquitectónicos.
La representación del museo portátil. Un concurso para un contenedor icónico
Authors: Falcón Meraz José Manuel
Published: November 2020

La idea de una arquitectura transportable ha estado presente a lo largo de la historia. Diferentes arquitectos han experimentado con este concepto, logrando materializarlo en tipologías como el pabellón en exposiciones internacionales. En esta misma línea, el museo, como tipología que busca acercarse a las masas, ha encontrado en lo portátil una variante útil. Si las exposiciones rotativas adquieren su valía en su contacto constante con el público, la idea de llevar la exhibición junto con la arquitectura se vuelve pertinente. Así, en este trabajo se analiza la experiencia paradigmática de la Fundación Guggenheim, institución museística puntera, en el concurso para un museo temporal en Tokio. Mediante el análisis de las propuestas de Ban, Nouvel y Hadid, se observará, cómo los arquitectos, ante una innovación tipológica y buscar convencer, utilizan toda la fuerza de sus estilos representacionales, para comunicar contenidos arquitectónicos originales que, serán el objeto principal de la muestra.

Published: November 2020

Abstract. Dust aerosol is important in modulating the climate system at local and
global scales, yet its spatiotemporal distributions simulated by global
climate models (GCMs) are highly uncertain. In this study, we evaluate the
spatiotemporal variations of dust extinction profiles and dust optical depth
(DOD) simulated by the Community Earth System Model version 1 (CESM1) and
version 2 (CESM2), the Energy Exascale Earth System Model version 1
(E3SMv1), and the Modern-Era Retrospective analysis for Research and
Applications version 2 (MERRA-2) against satellite retrievals from
Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP), Moderate
Resolution Imaging Spectroradiometer (MODIS), and Multi-angle Imaging
SpectroRadiometer (MISR). We find that CESM1, CESM2, and E3SMv1
underestimate dust transport to remote regions. E3SMv1 performs better than
CESM1 and CESM2 in simulating dust transport and the northern hemispheric
DOD due to its higher mass fraction of fine dust. CESM2 performs the worst
in the Northern Hemisphere due to its lower dust emission than in the other
two models but has a better dust simulation over the Southern Ocean due to
the overestimation of dust emission in the Southern Hemisphere. DOD from
MERRA-2 agrees well with CALIOP DOD in remote regions due to its higher mass
fraction of fine dust and the assimilation of aerosol optical depth. The
large disagreements in the dust extinction profiles and DOD among CALIOP,
MODIS, and MISR retrievals make the model evaluation of dust spatial
distributions challenging. Our study indicates the importance of
representing dust emission, dry/wet deposition, and size distribution in
GCMs in correctly simulating dust spatiotemporal distributions.
Indicators of Antarctic ozone depletion: 1979 to 2019
Authors: Bodeker Greg E. , Kremser Stefanie
Published: November 2020

Abstract. The National Institute of Water and Atmospheric Research/Bodeker Scientific (NIWA-BS) total column ozone (TCO) database, and the associated BS-filled TCO database, have been updated to cover the period 1979 to 2019, bringing both to version 3.5.1 (V3.5.1). The BS-filled database builds on the NIWA-BS database by using a machine-learning algorithm to fill spatial and temporal data gaps to provide gap-free TCO fields over Antarctic. These filled TCO fields then provide a more complete picture of winter-time changes in the ozone layer over Antarctica. The BS-filled database has been used to calculate continuous, homogeneous time series of indicators of Antarctic ozone depletion from 1979 to 2019, including (i) daily values of the ozone mass deficit based on TCO below a 220 DU threshold, (ii) daily measures of the area over Antarctica where TCO levels are below 150 DU, below 220 DU, more than 30 % below 1979 to 1981 climatological means, and more than 50 % below 1979 to 1981 climatological means, (iii) the date of disappearance of 150 DU TCO values, 220 DU TCO values, values 30 % or more below 1979 to 1981 climatological means, and values 50 % or more below 1979 to 1981 climatological means, for each year, and (iv) daily minimum TCO values over the range 75° S to 90° S equivalent latitude. Since both the NIWA-BS and BS-filled databases provide uncertainties on every TCO value, the Antarctic ozone depletion metrics are provided, for the first time, with fully traceable uncertainties. To gain insight into how the vertical distribution of ozone over Antarctica has changed over the past 36 years, ozone concentrations, combined and homogenized from several satellite-based ozone monitoring instruments as well as the global ozonesonde network, were also analysed. A robust attribution to changes in the drivers of long-term secular variability in these metrics has not been performed in this analysis. As a result, statements about the recovery of Antarctic TCO from the effects of ozone depleting substances cannot be made. That said, there are clear indications of a change in trend in many of the metrics reported on here around the turn of the century, close to when Antarctic stratospheric concentrations of chlorine and bromine peaked.
Ice Algae Model Intercomparison Project phase 2 (IAMIP2)

Abstract. Ice algae play a fundamental role in shaping polar marine ecosystems and biogeochemistry. This role can be investigated by field observations, however the influence of ice algae at the regional and global scales remains unclear due to limited spatial and temporal coverage of observations, and because ice algae are typically not included in current Earth System Models. To address this knowledge gap, we introduce a new model intercomparison project (MIP), referred to here as the Ice Algae Model Intercomparison Project phase 2 (IAMIP2). IAMIP2 is built upon the experience from its previous phase, and expands its scope to global coverage (both Arctic and Antarctic) and centennial timescales (spanning the mid-twentieth century to the end of the twenty-first century). Participating models are three-dimensional regional and global coupled sea ice–ocean models that incorporate sea-ice ecosystem components. These models are driven by the same initial conditions and atmospheric forcing datasets by incorporating and expanding the protocols of the Ocean Model Intercomparison Project, an endorsed MIP of the Coupled Model Intercomparison Project phase 6 (CMIP6). Doing so provides more robust estimates of model bias and uncertainty, and consequently advances the science of polar marine ecosystems and biogeochemistry. A diagnostic protocol is designed to enhance the reusability of the model data products of IAMIP2. Lastly, the limitations and strengths of IAMIP2 are discussed in the context of prospective research outcomes.
Estimation of rainfall erosivity based on WRF-derived raindrop size distributions
Authors: Dai Qiang , Zhu Jingxuan , Zhang Shuliang , Zhu Shaonan , Han Dawei , Lv Guonian
Published: November 2020

Abstract. Soil erosion can cause various ecological problems, such as land
degradation, soil fertility loss, and river siltation. Rainfall is the
primary water-driven force for soil erosion, and its potential effect on
soil erosion is reflected by rainfall erosivity that relates to the raindrop
kinetic energy. As it is difficult to observe large-scale dynamic
characteristics of raindrops, all the current rainfall erosivity models use
the function based on rainfall amount to represent the raindrops' kinetic
energy. With the development of global atmospheric re-analysis data,
numerical weather prediction techniques become a promising way to estimate
rainfall kinetic energy directly at regional and global scales with high
spatial and temporal resolutions. This study proposed a novel method for
large-scale and long-term rainfall erosivity investigations based on the
Weather Research and Forecasting (WRF) model, avoiding errors caused by
inappropriate rainfall–energy relationships and large-scale interpolation.
We adopted three microphysical parameterizations schemes (Morrison, WDM6,
and Thompson aerosol-aware) to obtain raindrop size distributions, rainfall
kinetic energy, and rainfall erosivity, with validation by two disdrometers
and 304 rain gauges around the United Kingdom. Among the three WRF schemes,
Thompson aerosol-aware had the best performance compared with the
disdrometers at a monthly scale. The results revealed that high rainfall
erosivity occurred in the west coast area at the whole country scale during
2013–2017. The proposed methodology makes a significant contribution to
improving large-scale soil erosion estimation and for better understanding
microphysical rainfall–soil interactions to support the rational
formulation of soil and water conservation planning.
ANALYSIS OF THE EVOLUTION OF GULLY EROSION IN OLIVE GROVES USING PHOTOGRAMMETRY TECHNIQUES. RELATIONSHIPS WITH RAINFALL REGIME
Authors: Fernández T. , Gómez-Lopez J. M. , Pérez-García J. L. , Cardenal J. , Delgado J. , Tovar-Pescador J. , Sánchez-Gómez M. , Calero J.
Published: November 2020

Abstract. Gully erosion is one of the main processes of soil degradation, reaching 50%–90% of total erosion in basins. As erosion processes are related to rainfall regime, the depletion and deposition rates can be increasing in a climate change scenario. This paper deals with the quantification of erosion processes in an active gully affecting olive groves of the province of Jaén (southern Spain), using geomatics techniques (photogrammetry and LiDAR). Eight historical aerial flights from 1980 to 2016, a LiDAR dataset (2014) and 2 recent UAS surveys (2019–2020) were used and processed in a common reference system with the support of field GNSS ground control points. Then, DSMs and orthophotographs were obtained and DSMs of differences (DoDs) calculated, from which we can identify gullies, calculate the depletion and deposition areas, and estimate height differences and volumes involved. These analyses result in an average depletion of about −1.6 m (incision) and a waste volume up to 30000 m3 (soil losses), which lead to a rates of −0.05 m/year and −44 t/ha*year, respectively. These rates are very different along the considered periods, reaching the maximum values (near −300–450 t/ha*year) in 2009–2011 and 2011–2013, coinciding with the periods of higher rainfall in the last fifty years, that probably have underwent an increase of 10–30% in the last decades. Thus, the evolution of the gully area for 40 years has been analysed in relation to the rainfall regime that has been established from the daily rainfall data.
TRANSFORMATION TO SUSTAINABLE AND RESILIENT URBAN FUTURES IN SOUTHEAST ASIA
Authors: Lord F.
Published: November 2020

Abstract. The fast pace of urbanisation in Southeast Asia has undermined the sustainability of the social, economic and environmental infrastructure of many cities across the region. Urban resilience in Southeast Asian cities is being further impacted by the COVID-19 pandemic and climate change. While cities and national governments across the region have developed policies, strategies and programs to re-orient their cities towards more sustainable and resilient development pathways, many cities continue to struggle with the uncontrolled nature of urban development and compounding impacts of crisis events. This article provides an overview of major trends and challenges with urbanisation in Southeast Asia, focusing in particular on Cambodia and Vietnam, as well as the regional, national and sub-national policies and strategies established to address these trends and challenges. Given the current policy implementation gaps and ongoing challenges of urbanisation in Cambodia and Vietnam, the article makes the case for trans-disciplinary research to understand the potential for strengthening urban governance capacities for urban sustainability transformations.
SOCIO-ECONOMIC VULNERABILITY TO URBAN HEAT IN PHOENIX, ARIZONA AND DALLAS, TEXAS DURING JUNE 2020
Authors: Moss T. , Kar B.
Published: November 2020

Abstract. Urban expansion compounded by climate change appears to exacerbate the temperature difference between urban and rural areas. This temperature difference, known as the urban heat island (UHI) effect, results from lack of vegetation, increased impervious surfaces, excess heat released from human activities, and changing radiation and wind dynamics due to urban morphology. UHI has been found to increase heat-related illnesses, and in some instances, mortalities among vulnerable populations. Heat exposure is particularly pertinent in 2020, as stay-at-home orders and higher unemployment rates due to the COVID-19 pandemic have further exposed urban residents to local temperatures. Certain socio-economic groups that are more affected by COVID-19 are disproportionately exposed to high urban temperatures. We investigated the relationships between urban heat island intensity (UHII), normalized difference vegetation index (NDVI), and selected socio-economic factors for Dallas, TX and Phoenix, AZ for June 2020. We used an equal-weighting approach to combine socio-economic factors obtained from 2018 US Census Bureau data to determine socio-economic vulnerability, and used Landsat 8 imagery to derive NDVI and land surface temperature. Pearson’s correlation, hot spot analysis, and Moran’s I tests revealed that socio-economic vulnerability was higher in areas with high urban temperatures and decreased vegetation.

Abstract. Land restoration is of critical importance in Rwanda, where land degradation negatively impacts crop productivity, water, food and nutrition security. We implemented the Land Degradation Surveillance Framework in Kayonza and Nyagatare districts in eastern Rwanda to assess baseline status of key soil and land health indicators, including soil organic carbon (SOC) and soil erosion prevalence. We collected 300 topsoil (0–20 cm) and 281 subsoil (20–50 cm) samples from two 100 km2 sites. We coupled the soil health indicators with vegetation structure, tree density and tree diversity assessments. Mean topsoil organic carbon was low overall, 20.9 g kg−1 in Kayonza and 17.3 g kg−1 in Nyagatare. Stable carbon isotope values (d13CV-PDB ) ranged from −15.35 to −21.34 ‰ indicating a wide range of plant communities with both C3 and C4 photosynthetic pathways. Soil carbon content decreased with increasing sand content across both sites and at both sampling depths and was lowest in croplands compared to shrubland, woodland and grasslands. Field-saturated hydraulic conductivity (Kfs) was estimated based on infiltration measurements, with a median of 76 mm h−1 in Kayonza and 62 mm h−1 in Nyagatare, respectively. Topsoil OC had a positive effect on Kfs, whereas pH, sand and compaction had negative effects. Soil erosion was highest in plots classified as woodland and shrubland. Maps of soil erosion and SOC at 30-m resolution were produced with high accuracy and showed high variability across the region. These data and analysis demonstrate the importance of systematically monitoring multiple indicators at multiple spatial scales to assess drivers of degradation and their impact on soil organic carbon dynamics.

Using a zeroth-order optimization algorithm, simulations using controllers with randomly generated parameters are used to estimate the gradient and converge to an optimal set of those parameters.
We use kriging to visualize the design space and estimate the uncertainty, providing a level of confidence in the result. The procedure is applied to three problems in wind turbine control.
First, the below-rated torque control is optimized for power capture.
Next, the parameters of a proportional–integral blade pitch controller are optimized to minimize structural loads with a constraint on the maximum generator speed; the procedure is tested on rotors from 40 to 400 m in diameter and compared with the results of a grid search optimization.
Finally, we present an algorithm that uses a series of parameter optimizations to tune the lookup table for the minimum pitch setting of the above-rated pitch controller, considering peak loads and power capture.
Using experience gained from the applications, we present a generalized design procedure and guidelines for implementing similar automated controller tuning tasks.

The objective of this study was to evaluate the microbiological attributes of a Cohesive Yellow Latosol. Collections were carried out in three land use systems (LUS). The first, with natural rainforest (NR), the second with sugarcane (SC) cultivated since 2009, and the third under Mimosa cesalpiniifolia (MC) introduced in 1999. Microbiological analyzes were carried out by determining the carbon from microbial biomass, readily mineralizable carbon, microbial respiration, metabolic quotient, total organic carbon, microbial C/total organic C ratio, and occurrence of cellulolytic and ammonifiers microorganisms. Analysis of variance was performed to verify the different measures of microbiological attributes. The variation obtained from CMB was from 3.06 to 4 µg.C.g-1 in NR, 3.02 to 3.92 µg.C.g-1 in MC, and 3.14 to 3.24 µg.C.g-1 in SC. For accumulated CO2, no differences were found between environments, with values ranging from 77 to 55.70 µg.Kg-1 for NR, 80.30 to 49.56 for MC, and 80.30 to 49.56 for SC. qCO2 had no significant effect, and in relation to total organic carbon the forest soil (NR). These results demonstrate that the microbiological attributes of the soil are influenced by cover, environmental standards and soil management, and the sampling time. The forest soil showed superior microbial biomass when compared to other soils. The metabolic control detected a difference between the collection times. For the accumulated CO2 resources, no changes were observed.
Reflections of Social Darwinism on Physical Education and Sports in the Early Turkish Republican Period
Authors: Korkmaz Sevda

In the 19th century, with the spread of nationalism movement, the power and capital on which the state was based changed, and man replaced the land. Mechanization and industrialization accelerated imperialism, and the application of the emphasis on competition in nature to social spheres in the theory of evolution became a means to legitimize capitalist competition and the paths applied. In order to stand out in the competitive environment, both the durable workforce for economic progress and the military power to defend the imperial competition gains were of great importance. While this situation increased the value of human life and therefore their bodies, it also gave rise to the idea that strong bodies are the basis of strong states and caused it to become widespread in a short time. The number of recreational areas such as parks and gardens and sports facilities that would increase the life capacity and quality of people increased, physical education and sports were included in the education curriculum of military and civilian schools, scouting and gymnastics formations were supported and all these developments spread rapidly in Europe. The Ottoman Empire also considered physical education and sports as a way to get rid of destruction, and the Republic of Turkey, established in its place, gave a special importance to physical education and sports as a means of preserving and maintaining its existence as a means of building robust generations.

يمكن أن تمثل المعالجة السليمة لمياه الصرف الصناعي مصدرًا مهمًا للمياه العذبة التي يمكن إعادة استخدامها في العديد من تطبيقات المياه. على سبيل المثال، تعد تكنولوجيا الأغشية قادرة على القيام بمعالجة فعالة لتقليل محتوى الزيت في مياه الصرف الصناعي إلى مستوى مقبول. وتتمتع الأغشية البوليمرية التجارية الحالية بسهولة التصنيع وكفاءة فصل الزيت، ولكنها تعاني من تدهور الأداء مع الوقت والانسداد السريع. في هذه الورقة البحثية، نستعرض تصميم وتصنيع أغشيةٍ للترشيح الفائق تتكون من خليط البولي سيلفون وتركيزات قليلة من أكسيد الغرافين المعالج، واختبار هذه الأغشية في فصل الزيت من مياه الصرف الصناعي. في البداية، قمنا بمعالجة أكسيد الغرافين بمركبات عضوية تحتوي على المجموعات الأمينية والكربوكسيلية العضوية، وتم فحص التركيب الهيكلي ومكونات أكسيد الغرافين المعالج بواسطة المجهر الإلكتروني الماسح (SEM) المشتمل على مطيافية الأشعة السينية المشتتة للطاقة (EDX). وبعد ذلك، تم تصنيع عدد من أغشية مختلطة تحتوي على كميات قليلة من أكسيد الغرافين بما يعادل 0.05%، 0.1%، 0.2%، 0.4%، 0.8% بالوزن من كمية البولي سيلفون باستخدام تقنية الانقلاب الطوري (Phase Inversion). وقد أظهرت الأغشية المحتوية على أكسيد الغرافين المعالج قدرة عالية على التخلص من الزيت وخصائص ميكانيكية ممتازة مقارنة بالأغشية المصنعة من مادة البولي سيلفون فقط. كما توصلنا إلى أن كمية أكسيد الغرافين المعالج بالأغشية تؤثر بشكل كبير في خصائصها من معدل تدفق المياه خلالها، والتخلص من الزيت، ومقاومة ترسب المادة العضوية والبيولوجية على سطحها. كما توصلنا إلى أن التركيز المثالي من أكسيد الغرافين المعالج يتراوح بين 0.1-0.2% من وزن البولي سيلفون. وبما أن هذا المقدار الضئيل من أكسيد الغرافين المعالج لا يؤثر في تكلفة تصنيع الأغشية، ولا يغير من خصائص اللزوجة لمحلول خليط أكسيد الغرافين المعالج مع البولي سيلفون، فإنه لا يتطلب تغيير عملية التصنيع التجارية الحالية. في الختام، تشير نتائج الدراسة إلى أن الأغشية التي تحتوي على أكسيد الغرافين المعالج هي أغشية واعدة جدًا للاستخدام في عمليات معالجة المياه كفصل الزيت من الماء ويمكن أن تكون بمنزلة أساس للمعالجة المتقدمة لتيارات مياه الصرف الصناعي.
Génesis y evolución de la categoría realidad histórica en Ignacio Ellacuría
Authors: Brito Marcela
Published: November 2020

The main objective of this work is to present a evolutionary proposal of Ignacio Ellacuría's thought from a strictly metaphysical perspective. For this, the exhibition will be held in three fundamental moments: youth (1951-1962), approach to Zubirian philosophy and maturity project (1962-1974) and historical reality as a moment of maturity (1975-1989). In each of them a discussion is held around the fundamental problems that mark the development of Ellacuría's complex thought, in order to arrive at his proposal of the civilizational change that marked the reflections of the last years of his life and understand, of fraud, how his thinking has a novel and current character in our national and planetary conjuncture.

Evolução biológica versus Filo Cnidária: panorama dos últimos 10 anos (2010 – 2019) no Nordeste do Brasil
Authors: Pereira Bruno Michael Da Silva , Farias Mayara de
Published: November 2020

Introdução: a temática Evolução Biológica permeia transversalmente todas as áreas do conhecimento das Ciências Biológicas. Ainda assim, é carente de respostas que conectem o nosso presente ao passado, principalmente quando os objetos de estudo são invertebrados, pelo fato do difícil registro das estruturas morfofisiológicas desses organismos. Metodologia: o presente estudo buscou realizar um levantamento na literatura científica brasileira na Google Acadêmico dos últimos 10 anos (2010 – 2019) a respeito de estudos em Evolução relacionados ao filo Cnidaria, no Nordeste do Brasil, utilizando cinco search strings previamente pensadas para condução da busca sobre o tema sugerido. Resultados: foram encontrados 839 documentos e apesar da variação de palavras, depois da triagem, apenas 16 trabalhos foram computados. Trabalhos que tinham como áreas de conhecimento: Paleobiologia, Taxonomia integrativa, Biologia Molecular e Filogeografia. Nos trabalhos encontrados, Anthozoa foi a Classe de Cnidaria mais representativa. Oestado de Pernambuco teve a maior contribuição de estudos para a região. Conclusão: ainda que a busca tenha sido de trabalhos dos últimos 10 anos (2010 – 2019), os resultados dão um panorama parcial do real problema que é a falta de estudos que abranjam o tema Evolução, quando se trata de cnidários na região Nordeste do Brasil. Não se exclui a possibilidade da existência de outros trabalhos nesse período, mas com os instrumentos de busca utilizados os resultados demonstraram, mesmo que superficialmente, uma problemática geral, carente de estudos e novos pesquisadores com interesse pela temática, para que as demandas dos conhecimentos da área sejam supridas.
Discriminant analysis using fatty acids profile, stable carbon isotopes and tocopherols content as tool for feeding system prediction in Iberian pigs

Aim of study: The application of three analytical methods (fatty acids: FA, tocopherols: TOC, and isotope ratio: ISO) to distinguish the feeding type received by Iberian pigs during the fattening stage.Area of study: This distinction is very important for the labelling of Iberian high-quality products in the Quercus forest located on the southwest of Iberian Peninsula, where several production systems coexist.Material and methods: Discriminant analysis on fat samples with unknown background obtained from commercial pigs was applied. The feasibility of the combination method to determine the authentication of feeding background was studied on samples from different fattening system: free-range feeding with acorn and pastures (BE); free-range feeding acorn and pastures plus commercial feeds (RE); open-air feeding with commercial feeds (CA); standard feeding with commercial feeds (CE).Main results: In a first application of the methods, the overall success rate was 60.1% for FA, 49.7% for ISO and 49.3% for TOC. When some of the batches were reclassified attending to those previous results and additional information available about farm characteristics, ISO and TOC analyses had a 70% of success rate in the four categories, whereas FA showed 40.5%, attributable to the use of high-oleic commercial diets. The predictions improved with the method combination. The ISO+TOC combination achieved a 84.1% of success in prediction. When it was reduced to just two categories (acorn vs non-acorn), the success reached a 95% for FA+TOC and ISO+TOC.Research highlights: The use of these methods as a complementary tool for quality controls is highly recommended to avoid undesirable misclassifications.
