Casas y cambio cultural: metodología interdisciplinar para el estudio del espacio construido en la España rural contemporánea
Authors: González-Álvarez David , Alonso González Pablo
Published: August 2019

Este trabajo presenta una propuesta metodológica para el estudio interdisciplinar de las transformaciones recientes de la arquitectura doméstica en zonas rurales del estado español. Las casas constituyen un repositorio clave en las biografías y la memoria cultural de las comunidades que habitan estos territorios, funcionando como dispositivos destacados en la configuración de las identidades personales, familiares y comunitarias. Por ello, son un elemento adecuado para estudiar arqueológicamente las transformaciones sociales y productivas que atraviesan el medio rural del estado español. De hecho, el espacio construido es uno de los dispositivos más reconocibles en la articulación de estos procesos de cambio en la cotidianeidad de las comunidades rurales, donde la materialidad de los espacios domésticos juega un papel clave. La investigación aborda dos casos de estudio localizados en Maragatería (León) y Somiedu (Asturias), en el Noroeste ibérico. La reflexión teórica-metodológica sobre nuestros estudios arqueológicos, etnográficos y patrimoniales en marcha, junto a la consideración de investigaciones semejantes desarrolladas recientemente en otras zonas rurales del estado español e internacionalmente, sirven de eje conductor a este trabajo.

Published: August 2019

This article details the results of a descriptive study that analyzes the characteristics and impact of cyberbullying among native and immigrant students enrolled in secondary education. Results indicate that immigrant children experience higher levels than native students of cyberbullying victimisation and they also perpetrate bullying to a greater degree through digital media; there were significant differences in the majority of cases analysed (immigrant students had higher levels of victimisation and perpetration than native students in 27 of 33 cyberbullying incidents studied). In addition, the study found that immigrant students considered being a native of another country to be an explanatory factor in their experiences with cyberbullying. Both groups showed similar frequencies in the explanation given for perpetrating cyberbullying: they bullied in response to being provoked.

Nollywood Afrogeeks
Authors: Arthur Tori
Published: August 2019

Viewing Nigerian film, known as Nollywood, in online platforms provides African immigrants living in the United States with digital spaces to engage with the African continent through films with relatable Pan-African themes. Nollywood on social media sites (YouTube and subscription services IrokoTV, Amazon, and Netflix) marks the Nigerian film industry as a transnational participatory movement that enables immigrants to use the technology at their disposal to watch and comment on films, connect with their cultural values, and become a part of a global digital community of dispersed Africans and African descended populations. Thus, immigrants become a part of a Nollywood focused digital diaspora, a cultural space that illuminated the plurality immigrants negotiate on and off the continent.
The Influence of Migration and Crime on Development in Lagos, Nigeria
Authors: Ayodele Johnson Oluwole
Published: August 2019

Considering the implications of population movements for places of origin and destinations, migration has garnered significant interest in recent scholarship. To advance this objective, this chapter examines the influence of migration and crime on development in Lagos, Nigeria. The study used both quantitative and qualitative methods to collect data from 310 respondents. Data were analysed. Results show that 84.4% of Hausa, Yoruba (76%), others (73.3%) and Igbo (57.8%), planned their migration to Lagos. Overall, 95.8% of the respondents acknowledged that they had no assurances of jobs before migrating to Lagos. As frustration develops, some migrants embrace crime and endanger development. The study concluded that if development is inclusive, migration will be naturally controlled as individuals will remain in their places of origin rather than constituting nuisance to development in Lagos. It therefore suggests that government should control crime so that the people can see the possible constructive interactions between migration and development.
Library Signage and Information Graphics

Published: August 2019

Libraries are gradually becoming spaces for discovery, innovation, and community empowerment by catering to the various needs of the public. To harness the unlimited resources in the library, library digital signage is the perfect tool to help transform old buildings and spaces into a place of collaboration and innovation. Since it's a content-centric solution at its core, digital signs can go beyond looping a series of pictures. It's an intelligent tool that can tailor-fit content relative to the audience, location, time of the day, and even process. This chapter will address the different roles of signages and buttress the fact that digital signage can play a major role in this communication process in addition to demonstrating a “green” environment for library patrons. Graphic information can be displayed to the public in meeting rooms, at the front desk, in vestibules or cafeterias/cafes. The messaging can range from programs being held at the library to public service announcements to emergency messaging and so much more. There is no limit to the information that a library signage can convey to its users.

Chronic neuroinflammation is a key pathological hallmark of multiple sclerosis (MS) that suggests that resolution of inflammation by specialized proresolving molecules is dysregulated in the disease. Annexin A1 (ANXA1) is a protein induced by glucocorticoids that facilitates resolution of inflammation through several mechanisms that include an inhibition of leukocyte recruitment and activation. In this study, we investigated the ability of ANXA1 to influence T cell effector function in relapsing/remitting MS (RRMS), an autoimmune disease sustained by proinflammatory Th1/Th17 cells. Circulating expression levels of ANXA1 in naive-to-treatment RRMS subjects inversely correlated with disease score and progression. At the cellular level, there was an impaired ANXA1 production by CD4+CD25− conventional T and CD4+RORγt+ T (Th17) cells from RRMS subjects that associated with an increased migratory capacity in an in vitro model of blood brain barrier. Mechanistically, ANXA1 impaired monocyte maturation secondarily to STAT3 hyperactivation and potently reduced T cell activation, proliferation, and glycolysis. Together, these findings identify impaired disease resolution pathways in RRMS caused by dysregulated ANXA1 expression that could represent new potential therapeutic targets in RRMS.
Conservação da velocidade do CM de duas partículas sob a ação de forças de atrito em movimento unidimensional (D = 1)
Authors: Souza Carlos Eduardo Rodrigues , Thomaz Maria Teresa Climaco dos Santos , Souza Dácio M.
Published: August 2019

A força de atrito está presente no cotidiano dos alunos e a compreensão de sua ação sobre os corpos aproxima a Ciência de sua experiência. A lei de conservação do momento linear total, envolvendo sistemas de partículas sob a ação de forças dissipativas externas, não é geralmente discutida nos livros-texto de Mecânica Newtoniana utilizados nos ensinos médio e superior, nas instituições de ensino brasileiras. Discutimos neste trabalho o movimento mais simples que duas partículas podem ter: o movimento unidimensional em sentidos opostos, sob a ação de forças de atrito cinético externas. Mostramos que a conservação do momento linear do conjunto formado por essas partículas, sob a ação de duas forças de atrito cinético, ocorre apenas em partes do movimento unidimensional e quando elas se deslocam em sentidos opostos. Aproveitando o grande envolvimento dos alunos com aplicativos em celulares, apresentamos uma montagem experimental que verifica a conservação da velocidade do centro de massa (CM) desses dois corpos. O aparato experimental é simples e de baixo custo, podendo ser facilmente reproduzido em sala de aula como estratégia para estimular os estudantes a trabalharem com ferramentas matemáticas e métodos experimentais, de forma a discutirem situações físicas que incluem as forças de atritos presentes no seu dia a dia.

Um diálogo teórico-metodológico sobre a técnica no pensamento de Vitor Marinho
Authors: Dias Leon Ramyssés Vieira , Malina André , Azevedo Ângela Celeste Barreto
Published: August 2019

Os anos de 1980 foram marcantes para a Educação Física, pois disseminou-se o pensamento renovador e surgiu a perspectiva sociocultural. Nesse período, houve críticas à luz das Ciências Humanas e Sociais aos paradigmas positivistas (como o tecnicismo) nas produções da época. Dessa forma, o presente estudo teve por objetivo identificar a concepção da técnica na perspectiva sociocultural por meio da análise da obra de Vitor Marinho, um dos intelectuais responsáveis pela difusão do movimento renovador. Para tal, foram analisados três textos publicados pelo autor na década de 80, evidenciando os elementos explícitos e implícitos sobre a técnica e suas questões. Os dados foram tratados qualitativamente, embasados pelo referencial teórico de Álvaro Vieira Pinto. Os resultados apontaram que a mudança de referencial teórico-epistemológico que ocorreu com o pensamento renovador promoveu contribuições para pensar a técnica em uma perspectiva crítica e humanista, embora de forma imperfeita relativamente ao referencial teórico escolhido.

Published: August 2019

El objetivo del presente estudio fue explorar el proceso de postcarrera en la relación adulto mayor jubilado y trabajo. Se entrevistaron 12 jubilados trabajadores sobre las concepciones de jubilación y postcarrera; el proceso de transición, planeación y preparación para la postcarrera y el empleo puente como elección. En los resultados, se observó que la jubilación puede ser comprendida como un fin o una posibilidad; la familia y amigos como referentes importantes en la decisión de seguir trabajando; y el empleo como una de las modalidades de trabajo. Se concluye que el jubilado es el autor de su proyecto de vida personal, laboral y social y que el empleo puente tiene papel central en la postcarrera. En este sentido, se propuso transitar de la noción empleo puente a trabajo puente, para permitir una lectura más amplia en términos de las diversas modalidades de trabajo e incluyente en cuanto a los adultos mayores trabajadores no jubilados.

Published: August 2019

Este estudio mixto, de carácter exploratorio, reporta las principales tareas y obstáculos que enfrentan los ECE, así como las capacidades requeridas para abordarlas. El objetivo de este estudio es profundizar con evidencia empírica respecto al cargo del Encargado de Convivencia Escolar (ECE) en establecimientos municipales de Chile. Los resultados indican que realizan múltiples tareas emergentes y reactivas. Principalmente, atención de casos, supervisión y control de la disciplina y rendición de cuentas. Los principales obstáculos reportados son: cargos con fuerte énfasis en la rendición de cuentas internas y externas y que enfrentan dificultades para comprometer a profesionales y/o asistentes de la educación en un trabajo mancomunado. Para un óptimo ejercicio de su rol los ECE plantean la necesidad de desarrollar capacidades de liderazgo para movilizar a otros, gestionar conflictos y fomentar reflexiones en sus equipos. Los hallazgos plantean la necesidad de transitar más allá de un rol centrado en la contingencia a uno en gestionar la convivencia escolar, si lo que se busca es un rol cuyo propósito sea gestionar la co-construcción de una comunidad escolar que mejora de manera participativa, democrática e inclusiva.

Published: August 2019

O conceito de bem-estar subjetivo é complexo e multifacetado e relaciona-se com aquilo que cada pessoa pensa, avalia e sente sobre a sua própria vida, de acordo com a suas circunstâncias individuais e sociais. O objetivo deste estudo é comparar os níveis de bem-estar subjetivo das crianças em acolhimento familiar e em acolhimento residencial, relativamente às crianças na população geral, e compreender a influência no bem-estar subjetivo das crianças de fatores como a escola ou a relação que desenvolvem com pares e adultos. A amostra é composta por três grupos: 238 crianças que vivem na população geral, 145 em acolhimento residencial e 39 em acolhimento familiar. Os dados foram obtidos através da aplicação do questionário International Survey of Children's Wells Os resultados indicam que as crianças em acolhimento residencial têm um menor bem-estar subjetivo em comparação com os grupos de crianças em acolhimento familiar e na população geral. É essencial e urgente desenvolver programas de acolhimento familiar que proporcionem a um número crescente de crianças a possibilidade de crescerem num ambiente familiar, e requalificar as casas de acolhimento residencial em Portugal.

Authors: Espinosa-Cristia Juan Felipe , Alarcón José Ignacio
Published: August 2019

En Chile la propina se entiende como una recompensa económica que excede la cantidad establecida para pagar un servicio y generalmente se comunica durante el "servicio de mesa". Los pagos son facilitados por un sistema ofrecido por la compañía TransBank. Este sistema permite que seis millones de chilenos usen tarjetas de débito y crédito para pagar bienes y servicios. Este estudio ofrece una lectura de la mediación técnica de los sistemas de "propinas" (punto de venta). El marco del estudio se basa en una lectura de la sociología económica y los conceptos de los enfoques Actor-Red. La investigación se realizó utilizando un enfoque etnometododiológico-sistémico para las interacciones entre clientes y garzones/as, empleando métodos de observación participante y entrevistas semiestructuradas en restaurantes y cafés ubicados en Santiago de Chile. Los resultados muestran que las tecnologías de la información como el sistema POS de TransBank y las tecnologías manuales como las facturas deben entenderse como dispositivos que normalizan no sólo la entrega sino también la cantidad de la propina, según las dimensiones organizativas e interaccionales que contextualizan el fenómeno de las propinas.
Numerical Study on Response Characteristics of Solid Rocket Pintle Motor
Authors: Sapkota Jeevan , Xu Yi Hua , Sun Hai Jun
Published: August 2019

Pintle technology is currently a versatile technology used in a solid rocket motor (SRM) to control the desired thrust by changing the nozzle throat area, while effectively controlling the chamber pressure at the same time. The sudden movement of the pintle can induce rapid changes in the flow field and the occurrence of pressure oscillations inside the combustion chamber. The analysis of such rapid changes is essential to design an efficient controllable pintle rocket motor for a better thrust regulation. Two-dimensional axisymmetric models with mesh generation and required boundary condition were designed to analyze the effects of three different pintle head shape models in SRM thrust regulation effect. Dynamic mesh method was used with specific velocity for moving plug/pintle in the numerical analysis of SRM thrust regulation. The effects of different pintle head models on the flow field, combustion chamber pressure, mass-flow rate, thrust and Mach number were investigated. According to the analysis of total pressure response time, the simulation data revealed that circular pintle head model responded faster among three different models. According to the thrust effect, parabolic pintle has the maximum value of thrust and the greatest total pressure recovery coefficient among all pintle head models.
Simulation and Prediction for a Satellite Temperature Sensors Based on Artificial Neural Network
Authors: Abdelkhalek Hamdy Soltan , Ziedan Ibrahim , Amal Mohamed
Published: August 2019

Spacecrafts in space environment are exposed to several kinds of thermal sources such as radiation, albedo and emitted IR from the earth. The thermal control subsystem in spacecraft is used to keep all parts operating within allowable temperature ranges. A failure in one or many temperature sensors could lead to abnormal operation. Consequently, a prediction process must be performed to replace the missing data with estimated values to prevent abnormal behavior. The goal of the proposed model is to predict the failed or missing sensor readings based on artificial neural networks (ANN). It has been applied to EgyptSat-1 satellite. A backpropagation algorithm called Levenberg-Marquardt is used to train the neural networks (NN). The proposed model has been tested by one and two hidden layers. Practical metrics such as mean square error, mean absolute error and the maximum error are used to measure the performance of the proposed network. The results showed that the proposed model predicted the values of one failed sensor with adequate accuracy. It has been employed for predicting the values of two failed sensors with an acceptable mean square and mean absolute errors; whereas the maximum error for the two failed sensors exceeded the acceptable limits.

Published: August 2019

Purpose

The aim of this study was to investigate the diagnostic value of renal parenchymal density differences in distinguishing between acute and chronic urinary dilatations.

Material and methods

Retrospectively, unenhanced CTs of 98 patients were evaluated. Thirty-three had acute urinary obstruction, and 33 had chronic urinary obstruction. Parenchymal density values (HU) and renal pelvic anterior-posterior (AP) diameters of all groups were evaluated by two different radiologists who were unaware of each other and the content of the study. The t-test was used to compare parenchymal densities and renal pelvic diameter differences with normal, acute urinary dilation and chronic urinary dilation groups.

Results

Of the 98 cases who were included in the study, 33 people were in the acute obstruction group (7 females, 26 males), and 33 were in the chronic obstruction group. However, the second observer (observer 2) found a statistically significant difference (p < 0.01) during the measurements of density between the obstructed and normal sides. While for the first observer (observer 1), the correlation between right and left renal density measurements of the normal cases was moderate at 0.576; correlation of measurements done by the second observer was found to be high at 0.777.

Conclusions

Pale kidney findings seems to be helpful in diagnosis of acute urinary occlusion, but different results are obtained with evaluations made by different observers. Moreover, it is not a specific finding because oedema can also be seen in some other conditions, such as acute pyelonephritis; for this reason, one must be careful during the evaluation of this finding.

Abstract. Anthropogenic emissions are a dominant contributor to air pollution. Consequently, mitigation policies have attempted to reduce anthropogenic pollution emissions in Europe since the 1990s. To evaluate the effectiveness of these mitigation policies, the German Ultrafine Aerosol Network (GUAN) was established in 2008, focusing on black carbon and sub-micrometer aerosol particles, especially ultrafine particles. In this investigation, trends of the size-resolved particle number concentrations (PNC) and the equivalent black carbon (eBC) mass concentration over a 10-year period (2009–2018) were evaluated for 16 observational sites for different environments among GUAN. The trend analysis was done for both, the full-length time series and on subsets of the time series in order to test the reliability of the results. The results show generally decreasing trends of both, the PNCs for all size ranges as well as eBC mass concentrations in all environments, except PNC in 10–30 nm at regional background and mountain sites. The annual slope of the eBC mass concentration varies between −7.7 % and −1.8 % per year. The slopes of the PNCs varies from −6.3 % to 2.7 %, −7.0 % to −2.0 %, and −9.5 % to −1.5 % per year (only significant trends) for 10–30 nm, 30–200 nm, and 200–800 nm particle diameter, respectively. The regional Mann-Kendall test yielded regional-scale trends of eBC mass concentration, N[30–200] and N[200–800] of −3.8 %, −2.0 % and −2.4 %, respectively, indicating an overall decreasing trend for eBC mass concentration and sub-micrometer PNC (except N[10–30]) all over Germany. The most significant decrease was observed on working days and during daytime in urban areas, which implies a strong evidence of reduced anthropogenic emissions. For the seasonal trends, stronger reductions were observed in winter. Possible reasons for this reduction can be the increased average ambient temperatures and wind speed in winter, which resulted in less domestic heating and stronger dilution. In addition, decreased precipitation in summer also diminishes the decrease of the PNCs and eBC mass concentration. For the period of interest, there were no significant changes in long-range transport patterns. The most likely factors for the observed decreasing trends are declining anthropogenic emissions due to emission mitigation policies of the European Union.

Abstract. The final aim of the EU funded Cheap-GSHPs project is to reduce the total installation cost of closed-loop shallow geothermal systems. As part of the project a Decision Support System (DSS) has been developed and released on the web, in order to support the design of new closed-loop geo-exchange systems. The Cheap-GSHP project addresses all the aspects involved in planning and dimensioning a new borefield and therefore, the DSS is composed of several databases and tools that collect and elaborate the preliminary data and information that are necessary during the sizing phase, such as the geological and drilling aspects as well as the heating and cooling building demand. This paper briefly introduces the content of the databases and the mapping methodology developed for the Cheap-GSHPs DSS. All these researches are further deepen in the EU project GEO4CIVHIC, with a special attention to the application of shallow geothermal systems for building conditioning to historical buildings.
3D MODELLING FOR VALORIZING 20TH CENTURY ARCHITECTURAL ARCHIVES:
THE CASE OF THE UNBUILT PROJECT FOR A THEATRE IN CAGLIARI BY CARLO

Published: August 2019

Abstract. The issue of conservation and valorisation of Cultural Heritage involves today 20th century architectural archives, that come to us with their often considerable amount of materials, where the predominance of the design drawings arises. Interpretation, fruition and sharing of archival materials aimed to deepening the knowledge of contemporary masters and architectural movements address the works of many international scholars. In particular, using the continuous innovations of digital modelling tools, a field of this research is developing reconstruction and new interpretations of masters’ unbuilt projects. The rise of H-BIM for modelling architectural heritage, has been flanked by some experiments really aimed to represent unbuilt architectures. This is the case presented in this paper: the unbuilt project for the “Teatro Comunale” in Cagliari, designed by Carlo Mollino between 1964 and 1965. The building has been digitally modelled and the potentialities of BIM tools are today in phase of evaluation, also in light of the aim to create a collection of reconstructive models of Mollino’s projects, to be shared on-line. In particular, in this phase of the research, we are exploring the potentiality of BIM aimed to evidencing the reliability of reconstructive modelling based on different documentary sources.
FROM LIDAR DATA TOWARDS HBIM FOR STRUCTURAL EVALUATION
Authors: Argiolas R. , Cazzani A. , Reccia E. , Bagnolo V.
Published: August 2019

Abstract. In HBIM processes, the extraction of geometric components from 3D point clouds data can sometimes be a complex process. The so-called Scan to BIM process has been widely utilized: deriving 3D models from point clouds often a local modelling of geometric components is necessary. This leads in most cases to use external modelling tools or complex local modelling processes. In both cases, we often get a model that cannot be reused for other items belonging to the same category, contravening the BIM philosophy. Vaulted systems are a typical example of complex elements that we can find in historical architecture. The paper presents the first results of an ongoing research on geometric modelling and structural evaluation of masonry ribbed vaults. An algorithm is developed to generate a NURBS surface of masonry vaults that, starting from the data extrapolated from the point cloud, allows to obtain an HBIM family. The research aims to overcome the inability to reference to standardised objects in local modelling of historical architecture elements. Directed to a standardization in the geometric modelling process of 3D laser scan data, the developed workflow is a possible alternative to commonly used workflows. Particular attention is focused on a case study of stellar vaults, a special class of masonry ribbed vaults whose three-dimensional geometry features a star-shaped projection on the horizontal plane. The work is carried out to verify that this family can be used for the structural analysis of stellar masonry vaults.
DEVELOPMENT OF GEOSPATIAL TECHNIQUES FOR NATURAL HAZARD RISK ASSESSMENT IN THAILAND
Authors: Phoompanich S. , Barr S. , Gaulton R.
Published: August 2019

Abstract. In order to mitigate environmental risk in Thailand it is essential to understand where and when specific geographic areas will be exposed to individual and multiple natural hazards. However, existing national scale approaches to natural hazard risk assessment are poorly adapted to deal with multiple hazards where significant uncertainties are associated with input variables and prior knowledge of the spatiotemporal nature of hazards is limited. To overcome these limitations, a geospatial approach has been developed that integrates machine learning within a GIS environment. Four hazards were investigated by Naïve Bayes while multiple hazards and their causalities were analysed via a Bayesian Network. Geospatial and Earth observation data representing past hazard events and their trigger variables were analysed to derive the probability of a hazard. Results revealed that lowland areas covering 22,868 and 139,193 km2, or 5% and 29% of total lowland areas were at-risk at a 90% probability-level of floods in rainy-seasons and droughts in the summer. High mountains and the plateaus were exposed to landslides over 90% probability in rainy, and forest fires in summer with over 60% probability, covering 37,727 and 40,069 km2, respectively. Within the Bayesian Network four relations of multiple hazards were investigated. At a 90% significance level approximately 190,250 km2 was at risk from a combination of forest fires and droughts. At a 80% or greater probability, 161,450, 120,027, and 102,628 km2 of land were at risk from a combination of 1) floods and landslides, 2) forest fires, floods, and landslides, and 3) all four hazards, respectively. The results were then used to produce the first fine-spatial scale multi-hazard assessment to support national policies on risk mitigation.
FLOOD EVACUATION ROUTES MAPPING BASED ON DERIVED- FLOOD IMPACT ANALYSIS FROM LANDSAT 8 IMAGERY USING NETWORK ANALYST METHOD

Published: August 2019

Abstract. Reported by National Disaster Response Agency of Indonesia (BPBD) as many as 94 dies, 149 injured, and more than 88 thousands homeless caused by floods in 2018. Besides bringing casualties to people and environment, the floods also affect the damages to transportation infrastructures in which vital to disaster emergency response operation e.g. evacuation process. Due to the complex impact of current disaster, the demands of providing a short-term response increases accordingly. Therefore, this research proposes a prototype of flood evacuation route utilizing network analyst method. The network analyst method particularly focus on finding alternative route based on time and distance. This research uses a flood simulation model derived from Landsat 8 imagery and terrain data. Subsequently, the simulation model divides the flood severity based on the depth which consist of < 0.3 m (slight), 0.3-0.5 m (moderate), and > 0.5 m (serious) in order to generate an impact analysis regarding the estimation of damages and casualties. In order to resemble the real situation of flood, barriers (e.g. flood area) are applied into the finding evacuation route procedure. Thereby, the estimated evacuation route can be executed considering the safest and fastest way. Moreover, some comparisons between before and after flood are conducted in order to know the effectiveness of evacuation routes. By such comparison proves that network analyst enables to support disaster management operation with respect to handling the evacuation procedure.
THE USE OF MULTI-TEMPORAL SENTINEL SATELLITES

CAUSED BY THE NUCLEAR POWER PLANT CONSTRUCTION
Authors: Çolak E. , Chandra M. , Sunar F.
Published: August 2019

Abstract. Turkey, due to increased demand for energy has made plans for nuclear power generation since 1970. Sinop Nuclear Power Plant, which will be built on Sinop İnceburun peninsula at the Black Sea coast of Turkey, is one of the three different nuclear power plants planned to be built in Turkey. The Sinop Nuclear Power Plant consist of four different reactors. The construction of the first unit is expected to be completed by 2023, and the fourth unit is planned to be activated by 2028. On the other hand, the construction of the nuclear power plant will alter the land use at the actual plant site and its surroundings and hence may cause significant environmental changes. As an indicator, more than 650000 trees have been cut so far for the construction of nuclear power plant, and this can adversely affect the ecological balances of the region by endangering habitats and creating ecological damages. The aim of this study is to analyse the land use/land cover changes (LULC) in the forestry-dominated areas due to the construction of nuclear power plants using the multi-temporal Synthetic Aperture Radar (SAR) and optical satellite images. For this purpose, different change detection methods such as SAR intensity image differencing, supervised image classification method (Support Vector Machine algorithm) were applied to Sentinel 1 satellite image datasets (2016-2019) to evaluate the annual changes due to construction. In addition, a correlation analysis was performed between the canopy structure and vegetation biomass using Sentinel 2 NDVI dataset (2016-2019) and calibrated Sentinel 1 backscatter values. Furthermore, using the Google Earth Engine (GEE), the Landsat 8 NDVI time series of the affected forest area, generated at 8-day intervals, was used to validate changes in vegetation.

Abstract. Beach litter destroys marine ecosystems and creates aesthetic discomfort that lowers the value of the beach. In order to solve this beach litter problem, it is necessary to study the generation and distribution pattern of waste and the cause of the inflow. However, the data for the study are only sample data collected in some areas of the beach. Also, most of the data covers only the total amount of beach litter. UAV(Unmanned Aerial Vehicle) and Deep Neural Network can be effectively used to detect and monitor beach litter. Using UAV, it is possible to easily survey the entire beach. The Deep Neural Network can also identify the type of coastal litter. Therefore, using UAV and Deep Neural Network, it is possible to acquire spatial information by type of beach litter. This paper proposes a Beach litter detection algorithm based on UAV and Deep Neural Network and a Beach litter monitoring process using it. It also offers optimal shooting altitude and film duplication to detect small beach litter such as plastic bottles and styrofoam pieces found on the beach. In this study, DJI Mavic 2 Pro was used. The camera on the UAV is a 1-inch CMOS with a resolution of 20MP. The images obtained through UAV are produced as orthoimages and input into a pre-trained neural network algorithm. The Deep Neural Network used for Beach litter detection removed the Fully Connected Layer from the Convolutional Neural Network for semantic segmentation.

Abstract. Recently, the drastic climate changes have increased the importance of wildfire monitoring and damage assessment as well as the possibility of wildfire occurrence. Estimation of wildfire damage provides the information on wildfire-induced ecological changes and supports the decision-making process for post-fire treatment activities. For accurate wildfire damage assessment, the discrimination between disaster-induced and natural changes is crucial because they usually coupled together. In this study, Sentinel-2 images were employed to assess the damage from a wildfire, which occurred in the coniferous forest of Gangneung, Gangwon Province, South Korea on April 2019. The images were captured from both Sentinel-2A and -2B, shortening the temporal interval of available pre- and post-fire images. Multi-temporal image analysis was performed in both object and pixel-based with two commonly used spectral indices, NDVI and NBR. Additional image pair from the same period of 2018 was used to distinguish the fire-affected regions from the naturally changed area and compared with the results from using only one pair of images from 2019. The experimental results showed that the change detection performance could be affected by the number of image pairs and spectral indices used to discriminate burned region from unburned region. Thus it verified the significance of adequately employing annual multi-pair satellite images for wildfire damage assessment.
CO2 effects on diatoms: a synthesis of more than a decade of ocean acidification experiments with natural communities
Authors: Bach Lennart Thomas , Taucher Jan
Published: August 2019

Abstract. Diatoms account for up to 50 % of marine primary production and are
considered to be key players in the biological carbon pump. Ocean
acidification (OA) is expected to affect diatoms primarily by changing the
availability of CO2 as a substrate for photosynthesis or through
altered ecological interactions within the marine food web. Yet, there is
little consensus how entire diatom communities will respond to increasing
CO2. To address this question, we synthesized the literature from over
a decade of OA-experiments with natural diatom communities to uncover the following: (1) if
and how bulk diatom communities respond to elevated CO2 with respect
to abundance or biomass and (2) if shifts within the diatom communities could be
expected and how they are expressed with respect to taxonomic affiliation
and size structure. We found that bulk diatom communities responded to high
CO2 in ∼60 % of the experiments and in this case more
often positively (56 %) than negatively (32 %) (12 % did not report
the direction of change). Shifts among different diatom species were
observed in 65 % of the experiments. Our synthesis supports the
hypothesis that high CO2 particularly favours larger species as 12 out
of 13 experiments which investigated cell size found a shift towards larger
species. Unravelling winners and losers with respect to taxonomic affiliation
was difficult due to a limited database. The OA-induced changes in diatom
competitiveness and assemblage structure may alter key ecosystem services
due to the pivotal role diatoms play in trophic transfer and biogeochemical
cycles.
Medicane Zorbas: Origin and impact of an uncertain potential
vorticity streamer

Abstract. Mediterranean tropical-like cyclones (Medicanes) can have high societal impact and their accurate forecast remains a challenge for numerical weather prediction models. They are often triggered by upper-level potential vorticity (PV) anomalies, such as PV streamers and cut-offs. But knowledge is incomplete about their detailed formation processes and factors limiting their predictability. This study exploits a European Centre for Medium-Range Weather Forecast (ECMWF) operational ensemble forecast with an uncertain PV streamer over the Mediterranean, which, three days after initialisation, resulted in an uncertain development of Medicane Zorbas in September 2018. Using an ad-hoc clustering of the ensemble members according to the PV streamer position, it is demonstrated that uncertainty in the initial conditions near an upper-level jet streak over the Gulf of Saint Lawrence is the dominant source of the subsequent uncertainty in the position of the PV streamer over the Mediterranean. The initial condition uncertainty strongly amplifies baroclinically after 18 h in a region of strong quasi-geostrophic forcing for ascent in the left exit of a jet streak over the North Atlantic. The further amplification and downstream propagation of the tropopause-level PV uncertainty leads to a large spread in the position of the PV streamer over the Mediterranean after three days, directly limiting the predictability of the position, thermal structure and evolution of Zorbas. Two low-level airstreams possibly play a key role in linking the uncertainties of the large-scale upper-level flow with meso-scale uncertainties in the cyclone structure. Overall, this study is an illustrative example that uncertainties in large-scale initial conditions can determine the practical predictability limits of a high-impact weather event.
