Open Lake Phosphorus Forcing of Cladophora Growth: Modeling the Dual Challenge in Great Lakes Trophic State Management
Authors: Zhou Xing , Auer Martin T. , Xue Pengfei
Published: September 2021

Stimulated by excess levels of phosphorus, the attached, filamentous green alga Cladophora grows to nuisance proportions in Lake Michigan, one of the Laurentian Great Lakes. While nearshore waters impacted by local sources of the nutrient continue to support nuisance conditions, offshore waters have undergone oligotrophication in response to reductions in phosphorus loading and benthification of phosphorus cycling by invasive dreissenid mussels. A concept termed the Dual Challenge recognizes that implementation of more stringent phosphorus-loading objectives (to control Cladophora in the nearshore) stands in conflict with a foreseen need to mitigate oligotrophication in the offshore (to sustain a healthy fishery). Attention to this nearshore–offshore dynamic calls into play the role of cross-margin phosphorus transport in mediating both endmembers of the conflict. We applied a biophysical model simulating soluble reactive (SRP) and particulate (PP) phosphorus, mussel biokinetics, and cross-margin mass transport in addressing the Dual Challenge. Pre- and post-dreissenid monitoring results suggest that a reduction in offshore PP levels (food web nutrition) in excess of 40% (2.4 to 1.4 mgP·m−3) has driven oligotrophication and attendant food web dysfunction. Yet, in the absence of local sources, model-predicted nearshore SRP levels remain at or below those required to prevent nuisance growth. These findings indicate that there is a margin of ~1 mgP·m−3 over which offshore PP levels could be increased (to the benefit of the food web and the fishery) without hindering efforts to reduce nuisance algal growth through local source control.
Spatial Pattern of Dissolved Nitrogen in the Water on Receiving Agricultural Drainage in the Sanhuanpao Wetland in China

Published: September 2021

The total nitrogen (TN) increases and the water quality deteriorates when a large amount of nitrogen-containing water is discharged from farmlands into wetlands. This research on the relationship between the TN, ammonia nitrogen (NH4-N), and nitrate nitrogen (NO3-N) concentrations in water has a certain reference significance for understanding the spatial pattern of nitrogen removal in wetlands. Taking the Sanhuanpao wetland in northeast China as the research object, 24 sampling plots in the study area were sampled in the spring and summer of 2017 to test the concentrations of TN, NH4-N, and NO3-N. Based on the calculations of the change rates of the TN, NH4-N, and NO3-N in spring and summer, a step-by-step elimination analysis was carried out and the spatial pattern of the TN, NH4-N, and NO3-N removals were revealed by gradual buffer extrapolations, combined with stepwise fitting functions. The results show that the removal capacity of NH4-N is strong within the range of 14.55 km–20 km and 26.93 km–35.96 km from the wetland inlet, and the removal capacity of NO3-N is relatively strong within the range of 26.93 km–35.96 km. The strong NH4-N and NO3-N removal areas in the wetland are not in the geometric center of the wetland, but in separate narrow areas around the center. The TN removal along water channel direction is only 0.25 times higher than that direction perpendicular to the channel, indicating that regardless of whether wetlands are expanded along the water channel or perpendicular to the water channel, the difference to the TN removal is small. Effectively monitoring and managing the reception of agricultural drainage is extremely important for maintaining the water-purification function of wetlands. The aim of the research is to reveal a spatial law of nitrogen removal in wetland water, and provide a framework for studying the mechanism of spatial difference of nitrogen.
Modeling as a Tool for Transboundary Aquifer Assessment Prioritization
Authors: Atkins Ashley E. P. , Langarudi Saeed P. , Fernald Alexander G.
Published: September 2021

Transboundary aquifers are critical global water supplies facing unprecedented threats of depletion; existing efforts to assess these resources do not adequately account for the complexities of transboundary human and physical system interactions to the determinant of the impact of assessment outcomes. This study developed a system dynamics model with natural, human, and technical system components for a section of the transboundary Mesilla Basin/Conejos-Médanos aquifer to evaluate the following dynamic hypothesis: how and when information from a transboundary aquifer assessment is reported and perceived, in scenarios where two countries follow identical and different timeframes, dynamically impacts the behaviors of the shared aquifer. Simulation experiments were conducted to quantitatively assess the dynamics of transboundary aquifer assessment information reporting and perception delays. These critical feedbacks have not previously been incorporated practically in simulation and analysis. Simulation results showed that the timing and content of reporting can change the dynamic behavior of natural, human, and technical components of transboundary aquifer systems. This study demonstrates the potential for modeling to assist with prioritization efforts during the data collection and exchange phases to ensure that transboundary aquifer assessments achieve their intended outcomes.
Nonstationary Design Flood Estimation in Response to Climate Change, Population Growth and Cascade Reservoir Regulation
Authors: Xie Yuzuo , Guo Shenglian , Xiong Lihua , Tian Jing , Xiong Feng
Published: September 2021

The hydrologic data series are nonstationary due to climate change and local anthropogenic activities. The existing nonstationary design flood estimation methods usually focus on the statistical nonstationarity of the flow data series in the catchment, which neglect the hydraulic approach, such as reservoir flood regulation. In this paper, a novel approach to comprehensively consider the driving factors of non-stationarities in design flood estimation is proposed, which involves three main steps: (1) implementation of the candidate predictors with trend tests and change point detection for preliminary analysis; (2) application of the nonstationary flood frequency analysis with the principle of Equivalent Reliability (ER) for design flood volumes; (3) development of a nonstationary most likely regional composition (NS-MLRC) method, and the estimation of a design flood hydrograph at downstream cascade reservoirs. The proposed framework is applied to the cascade reservoirs in the Han River, China. The results imply that: (1) the NS-MLRC method provides a much better explanation for the nonstationary spatial correlation of the flood events in Han River basin, and the multiple nonstationary driving forces can be precisely quantified by the proposed design flood estimation framework; (2) the impacts of climate change and population growth are long-lasting processes with significant risk of flood events compared with stationary distribution conditions; and (3) the swift effects of cascade reservoirs are reflected in design flood hydrographs with lower peaks and lesser volumes. This study can provide a more integrated template for downstream flood risk management under the impact of climate change and human activities.
Modelling the Influence from Biota and Organic Matter on the Transport Dynamics of Microplastics in the Water Column and Bottom Sediments in the Oslo Fjord

Published: September 2021

The fate of microplastics (MP) in seawater is heavily influenced by the biota: the density of MP particles can be changed due to biofouling, which affects sinking, or MP can be digested by zooplankton and transferred into fecal pellets with increased sinking rate. We hypothesize that seasonal production and degradation of organic matter, and corresponding changes in the plankton ecosystem affect the MP capacity for transportation and burying in sediments in different seasons. This is simulated with a coupled hydrodynamical-biogeochemical model that provides a baseline scenario of the seasonal changes in the planktonic ecosystem and changes in the availability of particulate and dissolved organic matter. In this work, we use a biogeochemical model OxyDep that simulates seasonal changes of phytoplankton (PHY), zooplankton (HET), dissolved organic matter (DOM) and detritus (POM). A specifically designed MP module considers MP particles as free particles (MPfree), particles with biofouling (MPbiof), particles consumed by zooplankton (MPhet) and particles in detritus, including fecal pellets (MPdet). A 2D coupled benthic-pelagic vertical transport model 2DBP was applied to study the effect of seasonality on lateral transport of MP and its burying in the sediments. OxyDep and MP modules were coupled with 2DBP using Framework for Aquatic Biogeochemical Modelling (FABM). A depletion of MP from the surface water and acceleration of MP burying in summer period compared to the winter was simulated numerically. The calculations confirm the observations that the “biological pump” can be one of the important drivers controlling the quantity and the distribution of MP in the water column.

Published: September 2021

Large-scale deep reservoirs associated with hydropower cascade development are known to influence the cycle of phosphorus (P). However, there is scarce information on the fractions and availability of P in sediments of large-scale deep reservoirs constructed due to hydropower cascade development. In this study, we researched the fractions and release mechanism of P in the sediments of large-scale deep reservoirs by analyzing the fractions and availability of P in the sediments of the Xiaowan (XW) and Nuozhadu (NZD) reservoirs in the middle and lower reaches of the Lancang River (China). According to the results, there is a significant difference in the P fractions in the sediments of the XW and NZD reservoirs, but not for the available P in the sediments. Compared to the NZD reservoir, there was less solid bioavailable phosphorus (BAP) in the sediments of the XW reservoir, but the replenishment degree of active solid phase P into pore water was higher in the XW. There was a significant positive correlation between the available P and the BAP; the Fe/P ratio measured by the diffusive gradients in thin films reflects the control of active iron (oxyhydr) oxides over labile P in the sediments. In addition to the reductive dissolution of iron-bound P, the release of P into the large deep reservoirs may be related to factors such as the sulfate reduction and the degradation of organic materials. The P cycling in deep reservoir sediments is mainly controlled by the Fe, and there is a clear spatial distribution of this mechanism in deep reservoirs.
Developing Green Infrastructure Strategies Based on the Analysis of Sewer System Critical Components

Published: September 2021

Flooding has presented a significant risk for urban areas around the world. Road inundation is one of the severe consequences leading to traffic issues and congestion. Green infrastructure (GI) offers further potential for stormwater management as an environmentally friendly and sustainable solution. However, sewer system behaviour has been overlooked in GI implementation. This study investigates sewer performance by measuring topological connectivity and hydraulic characteristics, and critical components are identified under different design storms. Three retrofit scenarios, including enlarged pipes (grey infrastructure, Grey I), rain gardens (GI), and the combination of enlarged pipes and increased rain gardens (GI + Grey I), are proposed according to the distribution of critical components. The results show that it is feasible to locate the vulnerable parts of the sewer system and GI site allocations based on the critical components that significantly impact the performance of the entire system. While all three scenarios can mitigate inundation, GI and GI + Grey I perform better than pipe enlargement, especially for runoff reduction during long-duration rainfall. Furthermore, the sewer behaviour and retrofit effect are dynamic under different rainfall patterns, leading to diverse combined effects. The discoveries reveal that the adaptation measures should combine with sewer behaviour and local rainfall characteristics to enhance stormwater management.
Smart Charging Needs, Wants and Demands, Charging Experiences and Opinions of EV Drivers
Authors: Brey Baerte de , Gardien Lotte , Hiep Ellen
Published: September 2021

To reduce emissions of harmful substances (such as CO2, NOx and particulate matter) from transportation a fuel transition is essential. Electric transport is one of the most promising options for achieving this. In order to make this new electric transport market function efficiently, new interactions between new and existing parties are required. The growth of electric transport increases the peak demand for electricity. This creates a greater mismatch between moments of supply and moments of demand. In other words, EV drivers want to have their car charged before departure, and grid operators need to allocate resources to meet this demand. Flexibility from both players is required. Charging must be further optimised (become “smarter”) to facilitate this flexibility. Smart charging means: controlling and optimising the time and speed of charging. For example, when there is a large supply of solar and wind energy, there is little other demand for electricity and the price for electricity is low. With the contribution of many organisations, the Vereniging Elektrische Rijders (VER) and ElaadNL have jointly investigated the experiences and opinions of electric drivers about the smart charging of electric cars with a broad survey called the “National Charging Research”. In total, more than 1800 Dutch electric drivers took part in this study. Among other things, the research paid attention to the way in which EV drivers charge their electric cars, which bottlenecks they experience (at home and away) and what the experience is with smart charging. The main finding was that many EV drivers are familiar with smart charging. They are willing to apply smart charging, but they want to be in control of their sessions. To give them that control, both insight and transparency are essential. To meet the needs and wants of both EV drivers and grid operators, alignment with the momentum of European legislation is required to avoid a mismatch of energy between moments of supply and demand.

REGIONAL SETTLEMENT SYSTEMS AND TERRITORIES WITH PREFERENTIAL MODES INTERACTION AND DEVELOPMENT PRINCIPLES
Authors:   National Research Moscow State University of Civil Engineering, YUSHKOVA N.G. ,   Volgograd State Technical University
Published: September 2021

The presence in the newest Russian urban planning practice of special objects of professional activity - local urbanized formations is revealed. Their appearance is due to the adoption of new regulatory legal acts in various sectors of activity, significantly expanding the scope of the Urban Planning Code of the Russian Federation. They establish general requirements for the formation of territories with preferential development regimes and their subsequent use, which contain the prerequisites for significant changes in the state of territorial objects and their systems. However, to date, they are not fully used either at the stage of developing urban planning documentation, or at the stage of its implementation. Urban planning practice indicates the need to establish the relationship between the properties and characteristics of regional systems of settlements and local formations, depending on environmental factors. As a result of the analysis and systematization of modern experience in the implementation of projects for the development of local territories, the influence of the activity of their urban development on the parameters of the functioning of regional systems has been established. The revealed dependence is proposed to be used in the development of model schemes for the reorganization of regional systems, which characterize their susceptibility to the emergence of new centers of urban development. The expediency of using the developed theoretical models in the process of improving the methodology of territorial planning has been substantiated. Purposeful planning of local territories in settlement systems is presented as forecasting the emergence of new foci of development through a comprehensive assessment and consideration of the available resource potential. Thus, it ensures the regulated development of the territory. This is expressed in the achievement of the predicted parameters of changes in the state of regional settlement systems, corresponding to the conditions and requirements of their functioning. The main difference between the proposed methodology and traditional approaches lies in the simultaneous provision of the stability of the formed spatial structures and the innovation of the forms of regional systems due to the activity of local formations.

The increase in the rate of global warming directly affects the safety of buildings and structures on permafrost. The research presents the problem of reliability analysis for piles on permafrost soils by the stability criterion under the action of tangential forces of frost heaving. The two groups of piles reliability analysis methods are developed: for complete and limited statistical data about random variables in the models of limit states. Approximations of the dependences of the design resistances of permafrost soils to the shear along the freezing surface on the temperature are proposed. It can be used to estimate the freezing force that keeps the pile from buckling. The method for reliability monitoring and durability forecasting has been developed for piles on permafrost soils. The proposed method makes it possible to reasonably reduce the cost of reliability analysis in the initial periods, which can increase the number of buildings and structures being inspected by the similar costs.

Published: September 2021

The modern workplace and the space in which it is located has been dynamically changing and modifying in recent years. Technological progress, in which we live and work, provides people with a lot of opportunities at the same time, but also creates challenges that must answered to them. Many have changed their workplaces so much that 20 years ago, office workers would have been hard to imagine. Freelancers and creative professionals today can work almost anywhere: in a park, in a cafe, in the subway, at home, and anywhere else where an idea comes up and an opportunity arises. The creative class, among other things, began to be highly valued, and many global brands are "hunting" for valuable personnel creating new products. For a creative professional, dynamics and variability, adaptability of space for various tasks are important. So, coworking spaces and creative spaces appeared, where free professionals could rent a table and chair for a day or a month and not be "tied" to one place for a long time, either financially or legally. Many companies and offices began to introduce creative techniques into the interior design of their spaces, make the space "flexible" and informal, create areas for communication and change of scenery, recreation, and places for brainstorming. This trend is gaining more and more interest every year and new places are being created that meet the challenges of our time. The study examines the types of creative spaces, ways of modifying traditional business spaces (offices) to create a creative atmosphere in them. On the example of the implemented project, the principles, and approaches in the design of spaces for creative specialists are clearly shown.

Nesta dissertação apresentamos o Quadro AC (AC é a sigla em inglês para Corrente Alternada). É uma tecnologia educacional que tem a finalidade de facilitar o ensino de circuitos elétricos com corrente alternada. Com ele pode-se realizar vários experimentos como ligações em série, em paralelo e mistas; medir a tensão e a intensidade da corrente elétrica durante os experimentos; explorar o funcionamento de um fotosensor, de um potenciômetro, de um transformador e do anel de Thomson. Além disso, com o Quadro é possível abordar também a lei das malhas, a lei do nós (leis de Kirchhoff) e a lei da indução de Faraday de forma investigativa. Ele pode ser utilizado em cursos regulares do Ensino Médio, cursos técnicos e superiores. Os seus pontos principais são a segurança para o usuário, o fácil manuseio e sua replicação. Apresentamos ainda um manual que detalha sua construção e permite ao professor construí-lo com a utilização de um ferramental doméstico e o uso de materiais de baixo custo. Explicamos o funcionamento detalhado de cada parte do produto através do seu manual e apresentamos um método de aplicação em sala de aula com uma Sequência de Ensino por Investigação (SEI) própria para o Quadro AC. A SEI permite a utilização do quadro por uma turma com muitos alunos de tal forma que todos participem durante toda a aula. Foi notável o engajamento da turma na atividade de construção dos experimentos. Os alunos exploraram de forma investigativa os elementos que compõem o Quadro AC e interagiram de forma ativa na discussão dos resultados produzidos por cada grupo ao executar as tarefas. As análises da aula foram feitas pelo professor com a utilização de diagramas de Venn. Essa análise permitiu visualizar a interação entre os componentes do Quadro e pode fornecer ao professor subsídios para tomada de decisões em relação ao aproveitamento da aula experimental com base nos conteúdos teóricos apresentados. A análise pode mostrar a necessidade de mudanças nos procedimentos como a teoria foi apresentada em sala de aula.
Частотно-контрастная характеристика ИК КРТ матриц в режиме работы с частично

Диоды ИК фотоприемной матрицы управляются входными пиксельными транзисторами, которые
определяют время накопления сигнала и рабочее напряжение на ИК фотодиодах. При обычных
рабочих условиях сопротивление входного транзистора намного меньше сопротивления фотодиода и
не лимитирует параметры работающего фотоприемного устройства. Входной пиксельный транзистор
определяет нагрузочную кривую, вдоль которой изменяются ток и напряжение ИК-фотодиода при
изменении входного фототока. Входные транзисторы открываются/закрываются изменением
напряжения на затворе. В случае хорошо открытых транзисторов полное изменение тока равно
изменению входного фототока.

Published: September 2021

В последнее десятилетие в отечественной фотосенсорике наметился ряд новых направлений,
связанных с расширением области применения матричных фотоприемных устройств (МФПУ)
коротковолнового инфракрасного диапазона спектра Short Wave Infrared (SWIR), прежде всего на
основе тройных соединений InGaAs [1, 2] и HgCdTe [3].
Это связано с некоторыми особенностями работы МФПУ SWIR-диапазона. Поскольку в
коротковолновой области используется излучение, отражённое от объектов, в сформированном с
помощью МФПУ изображении коротковолнового ИК-диапазона присутствуют тени и контраст, что
делает изображение, близким к видимому, что наиболее удобно для восприятия человеком. Данные
МФПУ также незаменимы в оптико-электронных системах переднего обзора ГСН сверхскоростных
объектов, в то время как тепловые ФПУ испытывают значительные искажения в связи с перегревом
обтекателя. Техническим решением задачи стробирования по дальности с построением 3D-изображений
является использование активно-импульсных систем в коротковолновой инфракрасной области спектра.
При этом для подсветки в исследуемой области спектра можно применять импульсное лазерное
излучение с длинами волн 1,06; 1,31; 1,55 мкм, соответствующее области спектральной
чувствительности материала InGaAs и окну прозрачности атмосферы. Существенным преимуществом
МФПУ на основе InGaAs является возможность работы без охлаждения или при охлаждении
фоточувствительной матрицы термоэлектрическими устройствами.

The core of the system is brought to the surface and located in a halo of kalifeldspar- muscovite metasomatites; the northwestern block is elevated and characterized by high-temperature epidote-biotite and epidote-pyroxene propylites, while in the southeastern block there is a consistent transition from kalifeldspar-sericite metasomatites to fragments of argillisite ones. The established zoning is confirmed by geochemical associations and mineralization types from the northwest to the southeast: in the northwest, Au-Bi (As, Cu) at the Solnechnoye ore occurrence; in the center, Mo (Cu, Au) at the Aksu deposit; in the southeast, Ag-Pb-Zn (Cu, Bi, As, Au) at the Vysokoye ore occurrence.

Type enriched with visual prosody is a powerful tool to encourage expressive reading. Visual prosody adds cues to text to guide vocal variations in loud-ness, duration, and pitch. More vocal variations result in a less monotonous voice and thus more expression. A positive e!ect of visual prosody is known on the voice of normal hearing readers and of signed bilingual deaf readers who developed signed language and spoken language. These deaf readers rely on speech as well as sign language and both modalities can be used interchangeably to compensate each other.

This preliminary study explores visual prosody in text in relation to Flemish Sign Language to see if sign language can be used to explain prosody. We asked deaf readers between 7 and 18 to relate prosodic cues to videos presenting prosodic components of Flemish Sign Language. We found that those readers connect the prosodic cues with the components in Flemish Sign Language as intended. Larger word-spacing cor-relates with a pause between signs, a wider font with a sign with ‘longer du-ration’, a thicker font with more ‘displacement’ in the sign, a raised font with a ‘faster velocity’ in the sign. However, some confusion occurred as participants seemed to extract only two prosodic components in the sign language: both the ‘faster velocity’ and ‘longer duration’ were referred to in terms of 'speed' and were not perceived as separate prosodic components. Participants were confused about why there were three cues in the text. Therefore, it is advised to re-evaluate and to re-design visual prosody for sign language with only ‘displacement’ and ‘speed’ in mind.
Popülizm Bağlamında Avusturya Özgürlük Partisi (Freiheitliche Partei Österreichs – FPÖ) ve Yabancı Düşmanlığı

Son yıllarda Avrupa genelinde aşırı sağ hareketlerin, yabancı düşmanlığının, ırkçılığın ve dini ayrılıkçılığın arttığı görülmüştür. Özellikle mültecilerin Avrupa'ya gelmesiyle birlikte, Avrupa'daki yabancı düşmanlığı ve Müslüman aleyhtarı muhalefet daha da belirginleşmekte ve bu sorun gün geçtikçe daha ciddi bir hal almaktadır. Bu kapsamda Avusturya ise aşırı sağcı bir siyasi partinin iktidara gelmesine izin vermiştir. Özellikle son yıllarda yabancı düşmanı, göçmen karşıtı ve Müslüman karşıtı söylemler üzerinden güç kazanan Avusturya’daki bu popülist Avusturya Özgürlük Partisi dikkatleri üzerine çekmekte ve kışkırtıcı bir dil kullanmaktadır. FPÖ, milliyetçi ve popülist yönleriyle; göç, Müslüman karşıtı ve yabancı karşıtı unsurları içeren popülist bir söylemsel strateji izlemektedir. Homojen popülizmi savunan Avusturya Özgürlük Partisi, ayrıca Avrupa Birliği/düzen karşıtı söylem ve stratejilerle ivme kazanmıştır.Söylemlere merkezi bir rol veren bu çalışmanın amacı Avusturya’daki popülist aşırı sağın yükselişinin mümkün olduğunca kapsamlı bir analizini yapmaktadır. Avusturya’nın seçilmesinin gerekçesi; bu ülkenin tarihinde aşırı sağın, aşırı sağın tarihinde de Avusturya’nın çok özel bir yeri bulunmasıdır.Bu çalışmada, Avusturya Özgürlük Partisinin Avusturya siyaseti bağlamındaki söyleminin milliyetçi ve popülist unsurları Eleştirel Söylem Analizi (Critical Discourse Analysis) yoluyla irdelenecek, muhtelif yönleriyle mukayese edilecektir. Eleştirel Söylem Analizi yoluyla yapılacak irdeleme ve mukayese 2001-2019 yılları arası dönemi kapsayacaktır. Çalışma, alanında metodolojik özgünlüğü taşımakla birlikte Avusturya’daki bu popülist aşırı sağ partinin söylemlerini nasıl meşrulaştırdıklarını ortaya koyacak ve alana güncel bir katkı sağlayacaktır. Ampirik olarak incelenecek Avusturya Özgürlük Partisinin resmi web siteleri, parti programları, kamuya açık konuşmaları, sosyal medya söylemleri, konuyla ilgili makaleler ve gazete içerikleri de nazara alınacaktır. Analiz konusu bu parti için önde gelen ve etkili bir politikacı mercek altına alınacaktır. Ancak ana odağın bireysel politikacıların söylemi olduğu izlenimini önlemek için, bu partinin diğer üyelerinin bazı söylem parçalarının yanı sıra parti programları gibi daha genel söylemsel materyaller de analize tabi tutulacaktır.

Proyecto "Voces desde el confinamiento: hibernación"
Authors: Galera Núñez María del Mar , Guichot Muñoz Elena
Published: September 2021

Este proyecto nace a partir de una situación personal totalmente nueva, una sensación de angustia permanente, de ambigüedad,de incertidumbre, de nuevas necesidades, una terrible sensación de impotencia, un golpe de realidad que ha hecho que nos demos cuenta de la importancia de aquellos gestos que pasábamos por alto, un paseo al aire libre, un reencuentro con amigos sin miedos, un beso en plena calle... experiencias que parecían imposibles de volver a recuperar, pues nos encontrábamos en plena tormenta... pero poco a poco, esta tormenta se apacigua, ya vemos cómo poco a poco está dejando de llover y sin duda, cada vez estamos más cerca de recuperar nuestra libertad y con ella, de disfrutar de aquellos pequeños gestos que nos harán de nuevo tan afortunados.

En "Voces desde el confinamiento" los alumnos y alumnas del Máster de Necesidades Específicas Educativas, realizaron un trabajo de introspección en el que se preguntaron: ¿cómo me siento? ¿qué es lo que siento?. En base a las respuestas a dichas preguntas, escribieron un pequeño texto en el que trataron de reflejar lo que sentían. El resultado plasmó, a través de imágenes, sonidos y la calidad de sus voces, todo aquello que hervía en su interior durante el confinamiento domiciliario que fue instaurado por el Gobierno Español durante el estado de alarma de 2020.

Con la llegada de la pandemia comenzó a oler a muerte, comenzamos a vivir y a morir en soledad. Llegó tan rápidamente, que tardamos en concienciarnos de lo que estábamos viviendo. Parecía todo tan surrealista cuando en verdad era la realidad que nos rodeaba. Hasta ahora España había sido mi casa y de repente me encontré atrapada en una jaula. El latido del corazón iba acelerando ya que no paraban de llegar correos donde me avisaban que habían cancelado todos los vuelos, no había manera de llegar a mi nido.

Esta pandemia ha sido capaz de parar el mundo entero y esto nos ha dejado sin palabras. En cada uno de nosotros se ha generado un baile de emociones ya que estábamos obligados a estar en casa, sin tener ningún tipo de contacto personal, sin poder llevar por delante nuestras rutinas. En mi mente había un caos, lo único que quería era despertar de esta pesadilla. Empecé a darme cuenta que fuera de mi casa estaba el peligro pero también los valientes. De hecho me hice fuerte y quise ver mi vida de otro color. Ya no la pintaba de negro, aunque las noticias nos entristecían, sino que de rojo. Sí, elegí el rojo porque es el color de la revolución. El covid19 me ha cambiado, me siento diferente. Valoro cosas que antes no valoraba tanto, como el hecho de poder llenar de besos a mi abuela, de montarme en un avión para ver a mi familia, de dar un abrazo a mis amigos y ver las sonrisas de las personas. Hay que vivir la vida y aprovecharla cada instante. Eso es lo que nos ha enseñado esta pandemia... todas crisis tiene una solución, un final y una enseñanza para la vida.

Proyecto ABLA: ¿a qué suenan mis emociones?
Authors: Galera Núñez María del Mar
Published: September 2021

¿A qué suenan nuestras emociones? En este proyecto los niños y niñas de infantil exploran las diferentes emociones a partir de los sonidos asociados con ellos. El resultado final de su aprendizaje se traduce en un pequeño teatro de sombras sonoras.

En el proyecto ABLAI las alumnas y alumnos del grado de Educación Infantil dentro de la asignatura de Didáctica de la Música, trabajaron por proyectos dentro de las aulas de infantil. Se partió de las preguntas y la curiosidad que los niños habían mostrado hacia determinados aspectos, para diseñar diferentes proyectos que se materializaron en distintos productos artísticos: mapas sonoros, canciones, vídeo-clips, cuentos sonoros, etc… Todo ello, contando con la tecnología como principal herramienta de diseño creativo. En cada uno de los vídeos se puede visualizar el producto obtenido y el making off en el que se explica cómo se elaboró.

Este recurso constituye un ejemplo de cómo se puede trabajar en base a la metodología ABLA. Los alumnos y alumnas del grado de educación infantil, generaron un espacio de aprendizaje en el aula de infantil a partir de una pregunta relacionada con un contenido propio de la etapa. Los resultados de aprendizaje de los niños y niñas se visibilizaron a través de la producción artística que se muestra aquí.

El contenido se asocia con la metodología didáctica y la manera de generar un espacio de aprendizaje estimulante. Asimismo se abordan los lenguajes artísticos como fuente, medio y vía de visibilización del conocimiento; la creatividad como competencia clave durante el proceso de aprendizaje; la resolución de problemas de forma colaborativa o el pensamiento crítico son otras de las competencias que son abordadas en este proyecto.

Aquatic Systems Biogenic Detritus Role in Metals and Metalloids Accumulation: Examples of Eight Heavy Metals and Arsenic
Authors:   Ostroumov S.A., Demina L.L.
Published: September 2021

The detritus role in the elements including heavy metals accumulation under the conditions of the controlled experimental systems. Detritus that was formed over 8 months in microcosms with Viviparus viviparus and Ceratophyllum demersum, contained As and heavy metals. Their concentrations in detritus were determined with atomic-sorption spectrometry (ASS) and were positioned in the following descending order (from the higher concentrations to the lower concentrations): Fe > Mn > Zn > Cu > Pb > As > Co > Cd > Cr. If a mixture of several heavy metals had been added to the experimental microcosm these metals (Fe, Mn, Zn, Cu, Co, Cd, Cr) were observed in the detritus material residue in higher concentration that in reference microcosm. The most distinct increase of the metals content in detritus in the microcosms with the added metals occurred for Cd (more than 3 times exceeding of the concentration in comparison with the reference one), Co (more than 13 times) and Cr (more than 150 times). These data confirm the proposed theory of the biota poly-functional role in water quality control and water self-purification.
