A flexible power management strategy for PV-battery based interconnected DC microgrid
Authors: Panda Mrutunjaya , Devara Vijaya Bhaskar , Salkuti Surender Reddy
Published: May 2021

In this paper, a coordinated power-sharing strategy for interconnected DC-microgrid (DC-MG) is proposed. The DC-MG consists of two subgrids with an interlinking bidirectional DC/DC converter (IBDDC). Each subgrid has a secondary-1 controller based on a state of charge (SoC) balancing based droop control strategy of the battery unit (BU). The proposed droop strategy regulates the DC bus voltage according to the SoC of BU. With the SoC balancing based droop method, BU with higher SoC supplies more power to the microgrid (MG) as compared to low SoC BU. The SoC information of batteries in all subgrids is communicated through low bandwidth communication (LBC). In case of failure of LBC, a secondary-2 controller is implemented for the battery controller to regulate the DC bus voltage considering the SoC of BU. Secondary-2 does not depend on the communication line. Considering the levels of DC bus voltages, a secondary power regulating controller is introduced for IBDDC. Further, a coordinated power control strategy is proposed for distributed generation to avoid overcharging of batteries. The whole system operates in a distributed way without a central controller. The proposed strategy has been verified in MATLAB/Simulink.

Background

To observe the therapeutic effect of conventional decompressive craniectomy with hematoma evacuation and frame-based stereotactic minimally invasive surgery (MIS) for supratentorial intracranial hematoma with herniation.

Methods

One hundred forty-nine patients with hypertensive ICH complicated with tentorial herniation were reviewed and analyzed in the present study. The intracranial hematoma was evacuated by emergency surgery within 6 h after admission. According to the authorized representatives’ wishes and consent, 74 of the 149 patients were treated by conventional decompressive craniectomy followed by hematoma removal, defined as the CDC group, and the remaining 75 patients underwent frame-based stereotactic MIS for ICH evacuation, defined as the MIS group. The intervals between the admission to surgery, the duration of surgery, the amount of iatrogenic bleeding, the occurrence of postoperative rebleeding, and the recovery of neurological functions were compared between the two groups. All patients were followed up for 3 months. Secondary epilepsy, survival in a vegetative state, severe pulmonary complications, mortality, and activities of daily living (ADL) classification were also recorded and compared.

Results

The interval between admission and surgery, the duration of surgery, and intraoperative blood loss in the MIS group were significantly decreased compared to the CDC group. The mortality rate, the rate of rebleeding, prevalence of vegetative state, and severe pulmonary complications in the MIS group were remarkably decreased compared to the CDC group. In the MIS group, the survivors’ (ADL) grade also showed advantages.

Conclusions

In the surgical treatment of hypertensive ICH complicated with tentorial herniation, frame-based stereotactic MIS for ICH showed advantages compared to conventional open surgery.
Spatial patterns in summertime surface ozone in the Southern Front Range of the U.S. Rocky Mountains

Published: May 2021

Summertime ozone in the Western United States presents a unique public health challenge. Changes in population, background ozone, wildland fire, and local precursor emissions combined with terrain-induced meteorology can affect surface ozone levels and compliance with the National Ambient Air Quality Standards (NAAQS). While there is considerable research on ozone in the Northern Front Range Metropolitan Area of Colorado, United States, less is known about the Southern Front Range. In Colorado Springs, approximately 100 km south of Denver, summertime maximum daily 8-h average (MDA8) ozone shows no significant (p < .05) trend at the 5th, 50th, or 95th percentile over the past 20 years. However, the region is at risk of nonattainment with the NAAQS based on observations from 2018 to 2020. From June through September 2018, the Colorado Department of Public Health and Environment measured hourly ozone at eight sites to characterize the spatial distribution of ozone in Colorado Springs. Mean ozone (±1σ) ranged from 34 ± 19 to 60 ± 9 ppb. The 95th percentile of hourly ozone increased approximately 1.1 ppb per 100 m of elevation, while the amplitudes of mean diurnal profiles decreased with elevation and distance from the interstate. MDA8 ozone was also highly correlated across all sites, and there is little evidence of local photochemical production or ozone transport from Denver. Further, results from generalized additive modeling show that summertime MDA8 in this region is strongly influenced by regional background air and wildfire, with smoke contributing an average of 4–5 ppb to the MDA8. Enhanced MDA8 values due to wildfires were especially pronounced in 2018 and 2020. Lastly, we find that the permanent monitoring sites represent the lower end of observed ozone in the region, suggesting that additional long-term monitoring for public health may be warranted in populated, higher elevation areas.

Transport of pollution into pristine wilderness areas is of concern for both federal and state agencies. Assessing such transport in complex terrain is a challenge when relying solely on data from standard federal or state air quality monitoring networks because of the sparsity of network monitors beyond urban areas. During the Front Range air quality study, conducted in the summer of 2008 in the vicinity of Denver, CO, research-grade surface air quality data, vertical wind profiles and mixing heights obtained by radar wind profilers, and ozone profile data obtained by an airborne ozone differential absorption lidar augmented the local regulatory monitoring networks. Measurements from this study were taken on 2 successive days at the end of July 2008. On the first day, the prevailing winds were downslope westerly, advecting pollution to the east of the Front Range metropolitan areas. On this day, chemistry measurements at the mountain and foothills surface stations showed seasonal background ozone levels of approximately 55–68 ppbv (nmol mol–1 by volume). The next day, upslope winds prevailed, advecting pollution from the Plains into the Rocky Mountains and across the Continental Divide. Mountain stations measured ozone values greater than 90 ppbv, comparable to, or greater than, nearby urban measurements. The measurements show the progression of the ozone-enriched air into the mountains and tie the westward intrusion into high-elevation mountain sites to the growth of the afternoon boundary layer. Thus, under deep upslope flow conditions, ozone-enriched air can be advected into wilderness areas of the Rocky Mountains. Our findings highlight a process that is likely to be an important ozone transport mechanism in mountainous terrain adjacent to ozone source areas when the right circumstances come together, namely a deep layer of light winds toward a mountain barrier coincident with a deep regional boundary layer.

Fibrodysplasia ossificans progressiva (FOP) and diffuse intrinsic pontine glioma (DIPG) are debilitating diseases that share causal mutations in ACVR1, a TGF‐β family type I receptor. ACVR1R206H is a frequent mutation in both diseases. Pathogenic signaling via the SMAD1/5 pathway is mediated by Activin A, but how the mutation triggers aberrant signaling is not known. We show that ACVR1 is essential for Activin A‐mediated SMAD1/5 phosphorylation and is activated by two distinct mechanisms. Wild‐type ACVR1 is activated by the Activin type I receptors, ACVR1B/C. In contrast, ACVR1R206H activation does not require upstream kinases, but is predominantly activated via Activin A‐dependent receptor clustering, which induces its auto‐activation. We use optogenetics and live‐imaging approaches to demonstrate Activin A‐induced receptor clustering and show it requires the type II receptors ACVR2A/B. Our data provide molecular mechanistic insight into the pathogenesis of FOP and DIPG by linking the causal activating genetic mutation to disrupted signaling.
El embarazo es una máquina, no una mujer» Deshumanización y sexismo misógino en el planteamiento favorable al ‘trabajo gestacional’
Authors: Delicado-Moratalla Lydia
Published: May 2021

El ‘embarazo profesional’ y la ‘gestante cyborg’ podrían parecer parte de una distopía propia de un futuro transhumanista, en el que no se vislumbra la gestación de la vida humana sin la intervención tecnológica o sin su integración en las lógicas mercantilistas. Sin embargo, ya son una realidad en algunos discursos académicos del ámbito queer y trans. En este ensayo realizo una reflexión feminista política y abolicionista en torno a la gestación subrogada y a la subsiguiente idea de ‘trabajo gestacional’. Poniendo en el centro al sujeto político mujer, parto de los argumentos de las pensadoras feministas críticas con esta práctica y me baso en las contribuciones etnográficas más destacadas sobre la temática. Analizo la deriva pro vientres de alquiler fijándome especialmente en los retos políticos que plantea con respecto a los derechos reproductivos de las mujeres. Examino el sexismo misógino que presentan neologismos como ‘gestante profesional’ y fórmulas similares. Compruebo que las propuestas favorables a la gestación subrogada tienen características clásicas de las prácticas androcéntricas, con una intención insistente por interponerse tecnológicamente en el proceso vital que es la gestación. Concluyo con la idea de que proletarizar y maquinizar la maternidad significa que se margina la experiencia humana para resignificarse desde el paradigma biocapitalista y desde el tecnopoder y ello conduce directamente a la deshumanización y a la explotación extrema de las mujeres.
Hearing, listening and deep neural networks in hearing aids
Authors: L Beck Douglas
Published: May 2021

Hearing aids have undergone vast changes in the last 30 years from basic analog sound processing techniques, to advanced digital technology, to Deep Neural Networks (DNNs) “on-the-chip” providing real-time sound processing. In addition to making sounds audible, advanced hearing aids with DNN on-the-chip are better able to provide clearer understanding of speech in noise, improve recall, maintain interaural loudness and timing differences, and improve the wearer’s ability to selectively attend to the speaker of choice in challenging listening situations. These improvements are delivered without acoustic feedback and with very high sound quality.

Published: May 2021

The influence of exploitation and abandonment of coal mines of the mining complex of Lviv-Volyn coal basin on the ecosystem of the region is considered. The main ecological problems of the territory are analyzed. It is established that the high technogenic pollution of the Chervonograd geological and industrial region is facilitated by the inflow of highly polluted drainage waters from the mine heaps and rock waste heaps of the Chervonograd Central Mining Plant into soils, surface, ground and underground waters. The negative impact of the heaps is caused by the high level of fault tectonics and fracturing of the bedrocks, the flat surface of the area. The influence of technogenic objects on the atmospheric air quality is analyzed. The main causes of the atmospheric air pollution are stationary sources of pollution. Technogenic objects have a significant impact on the quality of the the atmospheric air. The main role in the structure of pollutants belongs to sulphur anhydrite, carbon and nitrogen oxides, dust and soot. The amount of pollutant emissions into the atmospheric air from stationary sources of pollution for Chervonograd and Sokal districts has been analyzed according to the data of the Main Statistics Office in Lviv region. To prevent further deterioration of the ecological situation, it is recommended to form flat heaps, their reclamation and landscaping with the obligatory covering of the surface with a layer of neutral rocks, to keep measures to prevent burning of heaps. To stabilize the situation and to prevent further contamination of soil, surface and underground waters, the stable network of observations on the state of the geological environment, systematic geological and environmental monitoring should be carried out.

Geopolitical shift at a time of Covid-19 and the Asian Infrastructure Investment Bank: A case study of Chinese innovation in multilateralism
Authors: Morris David
Published: May 2021

How China will contribute to global governance has become a critical question in international relations, amplified by the linkages between the Covid-19 pandemic, escalating geopolitical contest and multilateralism in crisis. China has been doubling down on its authoritarian model of domestic governance while becoming more internationally assertive, including in existing and new multilateral institutions. Meanwhile, the United States appeared in recent years to be undermining the institutions, norms and rules of the liberal international order that it, itself, built. The subsequent decline in international cooperation poses grave risks to public health, economic and other forms of security. Can China cooperate with other actors to contribute public goods and stabilisation of global governance in such a deteriorating international environment? While there is a wide range of institutions in which to examine China's growing role in international governance, from United Nations bodies such as the World Health Organisation and World Trade Organisation to regional initiatives such as the Regional Comprehensive Economic Partnership, this paper examines the Asian Infrastructure Investment Bank (AIIB), an example of Chinese innovation in multilateralism. Established amidst geopolitical contest, the new institution seeks to address the Asian deficit of financing for sustainable development. The bank challenges a number of prevailing norms, including replacing the disproportionate power of the US and the advanced economies in the multilateral system with a more proportionate role for China and other developing countries; a new focus on infrastructure-led development which is built on Chinese confidence in the East Asian development model; and a shift away from the Bretton Woods practices of using financing conditions to drive liberal democratic and neo-liberal economic reforms. At the same time as representing a challenge to the traditional order, the bank exhibits – at least to date – best practices in implementation and addresses previously unmet concerns of the developing world. While it is not possible to extrapolate from only one initiative to draw comprehensive conclusions about China's likely future role in global governance, the AIIB case nonetheless suggests that, at least in some fields, China will challenge liberal norms to reform rather than revolutionise the international order.
Contemporary Archaeology as a Framework for Investigating the Impact of Disposable Plastic Bags on Environmental Pollution in Galápagos
Authors: Schofield John , Aylmer Jerry , Donnelly Andy , Jones Jen , Muñoz-Pérez Juan Pablo , Perez Elena , Scott Callum , Townsend Kathy A.
Published: May 2021

This paper presents contemporary archaeology as a novel framework for investigating environmental pollution, specifically marine pollution, which comprises a global “toxic assemblage” of an estimated 5.25 trillion plastic artefacts. The ideas behind this approach were developed in 2018 during a multidisciplinary “Science to Solutions” workshop held in Galápagos (Ecuador), led by the Galápagos National Park and Galapagos Conservation Trust and hosted by the Galapagos Science Center and the Charles Darwin Research Station. These ideas informed two studies which began separately but became increasingly aligned within a contemporary archaeology framework, in effect tackling the same problem from two very different perspectives: the first involving surface mapping, designed to inform an understanding of how plastic items enter the environment, including the marine environment, in the first place; and the second comprising utilization-focused evaluation, designed to better understand people’s behaviours and aspirations. Both of the studies centred on a specific and ubiquitous type of item or artefact: the disposable plastic bag. We conclude that the two studies together demonstrate that, through giving primacy to material culture, contemporary archaeology can (1) serve as a cross-disciplinary framework for tackling environmental pollution, and (2) provide a basis for shaping practice and informing policy.

Adsorption of Transition Metal Catalysts on Carbon Supports: A Theoretical Perspective
Authors: Chutia Arunabhiram
Published: May 2021

Adsorption is a fundamental process which takes place on a catalyst surface before it dissociates, diffuses over the surface and recombines with other adsorbed species to form the final product. Therefore, in theoretical chemistry understanding of the local geometrical and electronic properties of the adsorbed species on the catalyst surface has been a topic of core focus. In this short review we briefly summarise some of the important developments on theoretical studies related to the adsorption properties of transition metal (TM) catalysts on graphene and graphene-related carbon materials. Prior to this, we will present a discussion on various forms of carbon materials used as catalyst supports, which will be followed by a brief discussion of the fundamentals of the density functional theory (DFT).
Structural monitoring as a tool for the assessment of bridges
Authors: Vernooij Roel , de Melo Mark
Published: May 2021

As bridge engineers, we reach conclusions about the safety of structures by relying on data from analytical models. How do we know that the assumptions these models are based on are correct? To answer this question, a monitoring programme using sensors was implemented during the structural assessment of a 287 m span steel tied-arch bridge on the Dutch highway network. During a full traffic closure, a predefined truck was driven across the bridge multiple times, while 89 gauges recorded strains at locations of interest on the structure. The recorded measurements were compared with the results derived from the analytical model used for the assessment. The model validation considered the structural health monitoring measurements and compared them with the response of the finite-element model under codified moving loads. The measured structural behaviour was used to calibrate the model, which ensured that the analysis and safety assessment of the bridge were based on a validated model. The use of monitoring programmes on existing structures enables the engineering community to work towards a method to capture structural behaviour more accurately without excessive effort and overly complex models.

A educação é um dos meios fundamentais de se assegurar o desenvolvimento de uma sociedade, e, embora as tecnologias venham introduzindo um novo conceito de educação, diversas preocupações concernentes ao uso de ferramentas computacionais no processo de ensino e aprendizagem vêm se intensificando. Neste contexto, este trabalho investigou como o uso dessas ferramentas tem afetado o processo de ensino e aprendizagem de matemática na educação a distância (EaD). Para tal, duas pesquisas descritivas e quantitativas foram realizadas: a primeira via Google Forms, com a participação de 847 alunos dos cursos de Engenharia de Computação e Produção da Universidade Virtual do Estado de São Paulo (UNIVESP), que buscava identificar a percepção dos alunos no processo educacional mediado por ferramentas tecnológicas; e a segunda, por meio de nossos relatos de experiências pessoais enquanto facilitadores das disciplinas de Cálculo 3 e Métodos Numéricos. Os resultados indicaram que houve uma participação proporcional entre os alunos de ambos os cursos, com matrículas preponderantemente nos 2o e 3o anos letivos, dos quais 71% afirmaram ter tido algum professor ou facilitador que utilizou alguma ferramenta computacional. Os destaques ficaram para as ferramentas Microsoft Excel, Matlab e Scilab, cuja utilização foi preponderante nas disciplinas de Cálculo e Estatística, com elevadas taxas de aprovação (59%), estímulo (57%) e adequação (63%). Por sua vez, de acordo com os relatos de percepção dos facilitadores, metodologias alternativas como vídeos, animações e códigos de programação apresentaram um retorno positivo com maior associação entre teoria e prática. Assim, tendo em vista o processo de ensino e aprendizagem, este estudo sugere que o uso de ferramentas computacionais seja mais explorado no ensino de matemática na EaD.

Published: May 2021

Purpose. Consider the problems of a tourist destination on the example of a capital city with an emphasis on the structure, mechanism, basic elements and stages of high-quality tourist services, in the context of the formation of the destination "Kiev" as an element of a modern smart city.

Methodology. Analytical, statistical, graphic, systemic and comparative geographical methods were used.

Approbation. The main conceptual issues of the formation of tourist destinations and the problems of their accompanying components were studied by domestic scientists(M. Boyko, Y. Zabaldina, A. Mazaraki, S. Melnichenko, I. Smirnov, T. Tkachenko and others) and were tested in the previous works of the authors of this article.

Scientific novelty. The communication relationship of tourism service providers with their consumers is dictated by the availability of modern technologies, approaches and methods of forming tourist destinations as components of the smart tourism model. Today, the available theoretical, methodological and practical studies of smart tourism and smart destinations are controversial, given the fact that the scientific literature has not yet formed clearly theoretical constructions that would make it possible to formulate the main components of relationships in a smart destination. In this article, the authors have proposed an algorithm for the formation and development of the capital's smart city, using the example of the Kiev destination.

Practical significance. The article raises controversial issues related to the realities of modern life of people in the framework of innovative approaches to the activities of the tourism sector in Ukraine, with its problems, challenges and practical solutions. The publication materials can be used in the educational process in higher educational institutions that train specialists for the Ukrainian tourism industry, the practical activities of travel operators and agencies, in the process of work of departments and professional institutions, relate to the tourism system of providing services or the processes of studying the issues of the introduction of innovative technologies into the tourism sector of Ukraine.

Published: May 2021

The article actualizes the study of websites as a means to promoting cities around the world and highlights the main structural and semantic characteristics of advertising sites hosted on Internet platforms. The pragmatic role of a lexical unit of advertising texts is investigated. The concepts of website and advertising text are defined, the main ways of information transfer through advertising text were described. Definitions of the concepts such as advertising, advertising text, strategy, website, and related concepts are provided. After researching the selected advertising texts, the structural and semantic characteristics of advertising on websites, and the main ways of transmitting information, such as verb sentences, simple nominative sentences, and elliptical sentences are analyzed. The pragmatic means of advertising campaigns on websites includes constructions, such as Top + Numeral, Must + V., Let + Inf, and so on. Examples of pragmatic websites are also considered. Samples and purposes of using this approach are given. There are various strategies for advertising and promoting cities and countries around the world on Internet platforms. The most popular and effective are the use of different language techniques (motivational, interrogative, negative sentences) and the strategy of the association. The advertising text is noted to embody a communicative and pragmatic guideline. In the advertising message, there is a presentation of the goods to the target audience. Thus, the main load is the language code, which is aimed at a special category of people. A small number of works on this topic indicate the need for a more detailed study of the issue.

Abstract

In recent years, the companies management process has been modified in an attempt to respond more quickly to changes in business relationships and business scenarios. The dynamics are quite complex and require managers to control and plan their actions in the search for the success and maintenance of their companies in the market. This technical article uses the Linear Programming (PL) technique to optimize the production of various types of cheese in a dairy company in Jaraguari (MS), using the Solver - Excel tool to optimize profit. Secondary data were obtained from the research company, which had difficulties in improving its cheese production. The data collected were organized for the entry of the Solver, inputs and costs, considering the company's production restrictions, for four types of cheese. As a result, it is shown that the use of PL in the cheese production promoted an increase in profit of 30.98% to the company. With the performance of the sensitivity analysis, it was recommended to manufacture only two types of cheese, considering their costs and selling prices to the market. This decision-making procedure can be applied to other optimization activities in agro-industrial and sustainable production environments.

Um fator que ocorre em centros urbanos é a proliferação de mosquitos vetores de doenças, tais como o Aedes aegypti, sendo que em muitos casos os criadouros de mosquito ocorrem devido ao crescimento desorganizado das cidades que propiciam ambientes adequados para a proliferação desses vetores. Este estudo teve como objetivo analisar o monitoramento de mosquitos Aedes spp. em área nativa no município de Cuiabá, MT, bem como, comparar o efeito da atratividade das armadilhas ovitrampas com diferentes coloração e posição de instalação. Na área de estudo foram instaladas armadilhas em quatro pontos de amostragem, sendo que cada ponto continha 4 armadilhas: duas instaladas na posição de um metro acima do solo e outras duas instaladas ao nível do solo, sendo uma de coloração branca e outra de coloração preta em cada ponto, totalizando 16 armadilhas no ambiente. O delineamento estatístico utilizado foi um fatorial 2x2 sendo o primeiro fator a posição e o segundo fator a cor da armadilha. As populações dos mosquitos foram estimadas a partir de larvas e ovos coletados nas armadilhas ovitrampas, em quatro coletas semanais durante 42 dias. Houve diferença significativa entre as colorações das armadilhas e posição de instalação, demostrando que os mosquitos Aedes aegypti preferem a armadilha de cor preta a 1m de altura. Já para os mosquitos da espécie Aedes albopictus houve diferença significativa apenas entre a coloração das armadinhas, evidenciando que este mosquito prefere as armadilhas de cor preta.

Abstract

The objective of this study was analyze the monitoring of Aedes spp. mosquitoes in a native area in the city of Cuiabá, MT, as well as to compare the effect of the attractiveness of ovitraps traps with different color and installation. In the study area, traps were installed in four sampling points, being each point containing 4 traps: two installed at a position of one meter above the ground and two others installed at ground level, being one white and the other black in each point, totaling 16 traps in the environment. The statistical design used was a factorial 2x2, being the first factor the position and the second factor the color of trap. The mosquitoes populations were estimated from larvae and eggs collected in ovitraps traps, in four collections weekly in 42 days. There was a significant difference between the staining of the traps and installation position, demonstrating that Aedes aegypti mosquitoes prefer the black trap and in aerial position. However, for mosquitoes of the Aedes albopictus species, there was a statistical difference between the coloring of the enclosures, evidencing that this specie prefer the black traps.

Avaliação global do ensino médico brasileiro: interesses dos atores envolvidos
Authors: Bica Rafael Barbosa da Silva , Kornis George Edward Machado
Published: May 2021

O artigo estuda os interesses da corporação médica, da comunidade acadêmica e dos representantes do poder Executivo na estrutura da avaliação sistêmica do ensino médico brasileiro. Mostra-se que a corporação médica tende a apoiar avaliações de viés mais regulatório, contrapondo-se aos interesses da comunidade acadêmica. Argumenta-se que os representantes do poder Executivo sofrem demandas mutuamente antagônicas e que tensionam suas políticas: expandir a rede de ensino médico e regular sua qualidade. Conclui-se que a configuração assumida pelos sistemas de avaliação do ensino médico depende da articulação política dos atores envolvidos, da força das demandas sociais sobre o tema e do equilíbrio entre as prioridades governamentais de expansão do ensino médico e regulação de sua qualidade.

The main objective of the research was to characterize the innovation network and estimate an innovation adoption rate to evaluate its relationship with income generation in quinoa producers in Cabana. The characterization of the innovation network has been carried out using the social network analysis methodology (SNA), the innovation adoption index (IAI) has been obtained through an ordinal measurement scale and the return of the level of adoption of innovations on Producers' income has been estimated using the two-stage least squares methodology (TSLS) through the data obtained in a survey of 268 producers. The weak articulation of social capital has been evidenced in Cabana quinoa producers; however, the network of customers and input suppliers is well defined. Most of the producers stand out for their innovations in the productive component, the main weakness is related to the scarce innovation in the administration component. For each level of innovation adopted, a return of 49.09% on the income of the producer has been estimated, showing that the adoption of innovations has a greater impact on the generation of economic income compared to the years of schooling that only reaches 7.8%.
The Importance of Location Factors in Determining Land Prices: The Evidence from Bratislava Hinterland
Authors: Mariš Martin
Published: May 2021

Bratislava, the capital city of Slovakia, is currently experiencing a period of intensive suburbanisation, which in turn creates demand pressures and increases the price of urban land located in its hinterland. This paper investigates several locational factors, which likely significantly influence the demand for land plots and modulate `price-maker' conditions. Based on the population sample of 102 units, the results indicate that built-in infrastructure facilities on land under analysis, advanced transport connectivity in municipalities, and various amenities in the municipality cadastre tend to elevate land prices significantly. Moreover, the factor of distance from the city of Bratislava plays a major role in household location, which was identified by the apparent decreasing rent gradient pattern.

The assessment of the possibility of creating a plant-soil cover on an artificially created seal-gravel drainage layer with a rocky bed (h=110¸150 cm), on the disturbed areas of the adjacent areas of tailings storage facilities. Research for 2017–2019 shows that when sowing recult-vants with sowing standards of 150–200 kg/ha and doses of fertilizer N60P60K60 and N120P60K60 on an artificial substrate it is possible to form meadow formations with a density of grass 10–12000 pc/m2 and average productivity of 21–24 c/ha. A plant-soil-blooded blood with a turf layer of 8–10 cm is created with the simultaneous overlap of heavy metals of man-made substrates and elimination of pulp sands dusting, which contributes to the improvement of the microclimate of the environment.

Regression and neural network model for predicting the required dose of coagulant, depending on the quality of river water supplied for water treatment, are considered, their comparative analysis is carried out. For modelling and forecasting, statistical data collected for the period from 2005 to nowadays. Regression models were built on the true values of the factors (water quality indicators) and on their first differences to eliminate the trend in the series. For the models built on the true values, the statistical significance, was confirmed, high values of the coefficient of the determination were obtained, the values of the approximation errors were 22–25 %. In neural network modelling, networks of the multilayer perception were used. Generalization error on the test set when using other type of networks (RBF-networks, Elman networks), was significant above. Computational experiments have shown that, in general, the accuracy of neural network models is higher than regression ones. The average learning error was 7–9 %, the error on the test set increases to 12–16 %. The reliability of the forecast is increased by training the network on more recent data and using a larger set of facts. An increase in the influence of indicators of permanganate oxidability and colour of the initial river water on the dose of reagents with a simultaneous decrease in the degree of influence of alkalinity over the last five-year period was revealed. This confirms the need to periodically update data for building models. Selected models recommended for implementation in industrial monitoring of water treatment technology at the enterprise.
Mauricio Macri: historia mediatizada de un presidente argentino
Authors: Cicowiez Mariano
Published: May 2021

El estudio de las imágenes proselitistas de la fuerza política Propuesta Republicana (PRO), liderada por el expresidente Mauricio Macri (2015-2019), constituye una oportunidad para examinar los procedimientos técnicos y semióticos de comunicación utilizados para instalar y posicionar sus candidaturas a jefe de gobierno de la Ciudad Autónoma de Buenos Aires y luego a la Presidencia de la República Argentina. Con el objeto de reconocer regularidades y rupturas en su gramática de producción, en la investigación se analizan imágenes fijas e imágenes en movimiento divulgadas en medios tradicionales de prensa entre los años 2007 y 2019. La metodología ha consistido en la confección de un corpus de imágenes de uso electoral, las cuales han sido examinadas de manera intertextual. Los resultados indican que sus campañas se sustanciaron en la exposición de proximidad entre candidato y electores. Se concluye que este es, en la actualidad, el modelo vigente de comunicación electoral en Argentina.
“Enfermos, ladrones e inmorales” La diversidad sexual según dos revistas argentinas de principios del siglo XX
Authors: Ojeda Pablo Maximiliano
Published: May 2021

Este artículo indaga en las representaciones de la diversidad sexual tal y como eran expuestas por dos publicaciones argentinas, muy diferentes y dirigidas a públicos distintos, vigentes a principios del siglo XX. Se trata de la revista especializada Archivos de Psiquiatría, Criminología y Medicina Legal y del semanario humorístico de cultura general Fray Mocho. Se parte de la contextualización y el análisis de las profundas transformaciones que transitaba Buenos Aires con el cambio de siglo: el aluvión inmigratorio, el desarrollo urbano, el crecimiento económico, la modernización de los medios de comunicación y el incremento de la “mala vida”, que evidenciaban una complejidad social cada vez más dinámica; así, el corpus abordado permite identificar el paradigma estigmatizante de la época con respecto a la percepción de las sexualidades disidentes o no heteronormadas, que abarcaba desde lo médico-legal hasta las crónicas humorísticas leídas como pasatiempo.

Authors: Pérez Cosette Celecia
Published: May 2021

Este artículo parte de una revisión de los estudios sobre consumo cultural en Cuba para conectar ese estado del arte con otros estudios y perspectivas sobre consumo cultural, industrias, bienes culturales y medios masivos de comunicación que podrían enriquecer futuras aproximaciones, especialmente al abordar el mercado alternativo de producción y distribución de contenidos de entretenimiento por vías informales. Finalmente, se proyectan posibles escenarios que podrían derivarse de los entornos periféricos de producción, distribución y consumo de contenidos, y se analizan sus potencialidades poniendo en un lugar central los nexos entre el consumo de entretenimiento y la experiencia de la ciudadanía.
