The acoustic climate of spaces located under overpasses in the context of adapting them for outdoor public events – a pilot case study
Authors: Komarzyńska-Świeściak Elżbieta , Kozlowski Piotr
Published: January 2022

Due to the current shortage of traditional public space because of its privatization, commercialization, and securitization, there is an urgent need to reclaim areas affected by motorized traffic in the urbanized areas. On the other hand, the process of adapting them for new purposes should be carefully carried out, addressing several issues, among them environmental acoustics. This study is meant to contribute to our understanding of acoustic conditions of a general model of the bridge underspace. Therefore, the aim of the research was to examine the existing acoustic climate by measuring noise levels and comparing them with equivalent acceptable noise levels for the expected type of space development and Noise Rating curves. In this research, a pilot case study approach was used, as measurements were taken for a chosen space located under an elevated road that represents certain criteria set by the researchers. The results allowed us to: (1) verify the relationship between the geometry of the bridge underspace and the noise levels, (2) assess the initial acoustic conditions in terms of possibilities of acoustic adaptation of the examined space for outdoor public events, and (3) formulate hypotheses and preliminary assumptions for the planned further and broader studies of the issues raised in this article. The presented results and their analysis show that it is possible to bring the acoustic conditions in the studied space to the state required for public or cultural meeting spaces. In comparison with earlier findings, the research undertaken appears to be pioneering and the results can be used as valuable input for further research on this topic.
Equivalent circuit modeling in GaN wireless power transmission including stray inductance and capacitance by measuring radiated emission
Authors: Ide Toshihide , Shimizu Mitsuaki , Takada Noriyuki
Published: January 2022

We establish the method for estimating the stray elements of the GaN-WPT circuit by measuring the radiated emission around the GaN switching device. By controlling the circuit supply voltage, the spectrum peak shift due to the output capacitance of the GaN-HEMT is observed. It is found that these peak shift characteristics include the influence of both the stray wire inductance and stray capacitance. By fitting using the series resonance model, the value of the stray inductance and stray capacitance can be estimated in the non-destructive measurement in the GaN-WPT circuit.
Evaluation of thermal couple impedance model of power modules for accurate die temperature estimation up to 200 °C
Authors: Nakamura Yohei , Kuroda Naotaka , Nakahara Ken , Shintani Michihiro , Sato Takashi
Published: January 2022

This paper presents an experimental evaluation of the thermal couple impedance model of power modules (PMs), in which silicon carbide (SiC) metal-oxide-semiconductor field-effect-transistor (MOSFET) dies are implemented. The model considers the thermal cross-coupling effect, representing the temperature rise of a die due to power dissipations by the other dies in the same PM. We propose a characterization method to obtain the thermal couple impedance of the SiC MOSFET-based PMs for model accuracy. Simulations based on the proposed model accurately estimate the measured die temperature of three PMs with different die placements. The maximum error between measured and simulated die temperatures is within 8.1 °C in a wide and practical operation range from 70 °C to 200 °C. The thermal couple impedance model is helpful to design die placements of high-power PMs considering the thermal cross-coupling effect.

Authors: Hernández-Pajares Julio , Yagui Nishii Valeria
Published: January 2022

Es una realidad el creciente desarrollo del desempeño e información de desempeño ambiental en empresas peruanas, debido a la influencia institucional de la normativa internacional principalmente en organizaciones de actividades con mayor impacto de sostenibilidad, sin embargo, las prácticas de economía circular (EC) como concepto de desarrollo sostenible no presentan el mismo impulso.

Esta investigación busca analizar el nivel de cumplimiento de los indicadores de desempeño ambiental de acuerdo con la GRI y las prácticas de EC, y su relación con el tamaño y sector para empresas peruanas que han publicado su reporte de sostenibilidad voluntario para el año 2016.

Esta investigación cuantitativa tiene un alcance descriptivo y relacional, para ello se realiza un análisis de contenido de los reportes de sostenibilidad de las empresas para examinar las variables señaladas.

Los resultados señalan un mayor cumplimiento de indicadores de gestión ambiental de recursos, transporte y cumplimiento regulatorio, por otro lado, de las prácticas de EC la reducción de emisiones e insumos son las más divulgadas. El sector empresarial y el tamaño de las empresas solo encuentran relación con el nivel de información ambiental. La divulgación de prácticas de EC es menor que las prácticas ambientales y los aspectos revelados no presentan la implementación de sistemas de EC en su mayoría.

A robust event-driven approach to always-on object recognition
Authors: Grimaldi Antoine , Boutin Victor , Ieng Sio-Hoi , Benosman Ryad , Perrinet Laurent
Published: January 2022

We propose a neuromimetic architecture that can perform always-on pattern recognition. To achieve this, we have extended an existing event-based algorithm (Lagorce et al., 2017), which introduced novel spatio-temporal features as a Hierarchy Of Time-Surfaces (HOTS). Built from asynchronous events captured by a neuromorphic camera, these time surfaces allow to encode the local dynamics of a visual scene and to create an efficient event-based pattern recognition architecture. Inspired by neuroscience, we have extended this method to improve its performance. First, we add a homeostatic gain control on the activity of neurons to improve the learning of spatio-temporal patterns (Grimaldi et al., 2021). We also provide a new mathematical formalism that allows an analogy to be drawn between the HOTS algorithm and Spiking Neural Networks (SNN). Following this analogy, we transform the offline pattern categorization method into an online and event-driven layer. This classifier uses the spiking output of the network to define new time surfaces and we then perform the online classification with a neuromimetic implementation of a multinomial logistic regression. These improvements not only consistently increase the performance of the network, but also bring this event-driven pattern recognition algorithm fully online. The results have been validated on different datasets: PokerDVS (Serrano-Gotarredona and Linares-Barranco, 2015), N-MNIST (Orchard et al., 2015a) and DVS Gesture (Amir et al., 2017). This demonstrates the efficiency of this bio-realistic SNN for ultra-fast object categorization through an event-by-event decision making process.

Published: January 2022

Introduction. The aim of the study was to use comparative analysis for assessing efficiency of detection and confirmation of dual HIV infection, using conventional population sequencing (PS) and next generation sequencing (NGS) for an HIV-1 pol gene fragment, which encompasses protease and partially reverse transcriptase (positions 2253–3368).Materials and methods. The study was performed on intersubtype dual HIV infection model samples containing viruses of HIV-1 subtype B, sub-subtype A6 and recombinant form CRF63_02A1. Viruses were mixed pairwise in proportions from 10 to 90% to obtain 3 groups of model samples: CRF63vsB, CRF63vsA6, and A6vsB. The nucleotide sequences obtained by using PS and NGS technologies having 5, 10, 15, and 20% sensitivity thresholds for minor virus variants (NGS5–NGS20, respectively) were used to estimate the number of degenerate nucleotides or the degenerate base (DB) count and the number of synonymous mutations (SM) or the SM count. The fragment of the studied region (positions 2725–2981) was used for the analysis of operational taxonomic units.Results. The application of NGS5 proved highly efficient for detection of dual HIV infection in the model samples. The statistically significant (p 0.01) increase in DB and SM counts was demonstrated by NGS5 compared to PS. As a result, NGS5 helped detect dual HIV infection in 25 out of 27 model samples, while with PS it was detected only in 15 samples. The analysis of operational taxonomic units confirmed dual HIV infection in all the groups of model samples.Discussion. The efficiency of detection and confirmation of dual HIV infection depends both on the content of each virus in the sample and on genetic characteristics of these viruses. Conclusion. Using NGS genetic testing in routine practice will be instrumental for efficient identification of genetic characteristics of infectious agents and for thorough analysis of the epidemiological situation.
The (ir)resistible acceleration of digital education. The emergence of the blended school form in a state of education emergency
Authors: Landri Paolo
Published: January 2022

This article focuses on the recent acceleration of digital education triggered by the Covid19 pandemic. Protective measures, particularly the social distancing, translated into an institutional shock for the standard form of schooling. By drawing on a summary of current investigations on the topic (Brehm, Unterhalter & Oketch, 2021; Grek & Landri, 2021), the article describes how swift digitalization has reinforced the entanglement of public education into private owned and commercial platforms and paved the way to the emergence of the blended school form. The instabilities of the current process of institutional repair are underlined together with the risk of increasing unbalanced private and public partnership in the education system, and/or returning to the standard form of schooling in the future post-pandemic scenario.
La investigación social contemporánea: dificultades, problemas y desafíos.
Authors: Vera Rojas Mirella Del Pilar , Chávez Vera Luis Fernando , Vera Rojas Luis Antonio
Published: January 2022

El artículo propuesto centra su análisis en la reflexión de los problemas, dificultades y desafíos de la investigación social contemporánea, para lo cual fue necesario partir del debate histórico entre métodos de investigación cuantitativa y cualitativa y la inserción del positivismo en las prácticas de los investigadores, llegando a señalar sobre la bibliografía revisada de varios autores y autoras, propuestas de superación de este debate mediante la aplicación de “multimétodos”, de “métodos mixtos” o de la “triangulación metodológica” , dando lugar a diversas perspectivas de la investigación social y una serie de consecuencias en torno a su diseño, caracterizado por su flexibilidad, que adquiere confiabilidad y validez a través de metodologías como la “vigilancia metodológica”, “hacer observable lo inobservable” que junto con la “Teoría Fundamentada” permite a la metodología cualitativa superar la fragmentación en el análisis de los datos y al mismo tiempo conceptualizar y clasificar en forma más clara los datos provenientes de la base empírica. Posteriormente se analiza cómo superar el sentido común de los invetigadores a través de la teoría, tan necesaria para explicar la parte subyacente en las obervaciones sobre el mundo, donde la articulación teoría, método/técnica y base empírica es fundamental al momento de analizar los datos de la realidad que no se recogen, sino que se los producen a través del encuentro entre investigador e investigado, quienes construyen cooperativamente el conocimiento. Seguidamente se presenta una crítica a la investigación positivista imperante en el contexto ecuatoriano, que junto a políticas erradas entorpecen y muchas de las veces impiden el desarrollo de investigaciones en el campo social. Finalmente, se plantean desafíos a nuestras propias prácticas investigativas frente a los giros epistémicos de lo feminista, lo ambiental, lo decolonial, de la hermenéutica y de la complejidad; cerrando el análisis momentáneamente con la importancia de promover procesos éticos en la investigación social.

Published: January 2022

Los estilos de enseñanza se fundan en el conjunto de acciones mediadoras que se adoptan en las relaciones didácticas que implementa el entrenador para la organización de sus actividades de entrenamiento y las relaciones que establece en el proceso de enseñanzaaprendizaje. El objetivo del estudio permitió reconocer la formación profesional y los estilos de enseñanza de los entrenadores de fútbol base del Valle del Cauca. La metodología siguió la lógica descriptiva, la muestra de tipo no probabilístico por conveniencia y carácter voluntario estuvo constituida por 277 entrenadores con una edad promedio de 38 ± 12,2 años, y una experiencia promedio en el ejercicio de su profesión de 12,3 ± 9,1 años, los instrumentos utilizados fueron la encuesta sociodemográfica y el instrumento de estilos de enseñanza de teorías implícitas. Los resultados evidencian que los entrenadores empíricos con una experiencia novel presentan una tendencia hacia la utilización de estilos de enseñanza tradicional y técnica, mientras que los entrenadores con titulación profesional tienen una tendencia hacia estilos activos e interpretativos. En conclusión, la formación académica es fundamental en los procesos pedagógicos en el campo del deporte. Los entrenadores empíricos y con titulación profesional con poca experiencia no demuestran prácticas de enseñanza enfocadas hacia el estilo crítico; sin embargo, se evidencia un desplazamiento de estilos de enseñanza tradicional hacia estilos más comprensivos a partir de la experiencia en el ejercicio de su profesión.

Effect of Different Mulching Materials on Some Growth Parameters of Maize (Zea maysL) and Soil Physicochemical Properties.
Authors: E.U Chime , I.A Nweke , C.U Ibeh
Published: January 2022

Effects of different mulching materials on some growth parameters of maize and its influence on soil physicochemical properties were studied under Igbariamagro-ecology, during the rainy season of May to August 2019. The four types of mulches were laid out in a randomized complete Block design (RCBD), with four treatments and four replications. The four mulching treatments are Black polythene, while polythene, elephant grass, and no mulch, 5t/ha of cow dung manure was added to 18 experimental plots as Blank treatments. The growth, agronomic parameters, and soil physicochemical properties were monitored. Results indicated that elephant grass mulch significantly (P<0.5) increased the number of leaves, plant height, and stem girth when compared with other treatments. The treatments generally increased total porosity compared with the control. Bulk density and dispersion ratio significantly decreased in all treatments. There was a significant increase in aeration porosity. Field capacity and plant available water were significantly increased (p = 0.05). Buffer capacity, cation exchange capacity, and electrical conductivity were significantly increased with the application of treatments (p = 0.05). Particularly striking was the effect of Elephant grass mulch treatment on soil electrical conductivity which induced a 78.4±4.1 increase compared with the control 22.1±1.0. There was no significant increase in soluble cation. Therefore, elephant grass mulch could be applied alternatively in inorganic mulch and inorganic fertilizer for improved maize production.
Who published what on Somali health issues?
Authors: Bile Khalif , Emmelin Maria , Freij Lennart , Gustafsson Lars L , Sahlén Klas-Göran , Wall Stig , Warsame Yusuf Marian
Published: January 2022

In this editorial we attempt to define additional rationales for SHAJ, the Somali Health Action Journal, further to those presented in our inaugural editorial. We recognize the health information divide as one of the three health gaps characterizing the global health inequality landscape. The SHAJ venture emerged from a joint Somali-Swedish initiative to revive a former collaborative research programme also recognizing the need for a Somali-based platform for research communication. The members of the SHAJ Editorial team decided to join forces in designing and carrying out an empirical bibliometric study to assess the state of the art of the published literature on Somali health issues over a 75-year period covering major societal development eras in Somali academic history. This editorial is basically presented in the form of a report from this study, concluding with a statement on the policy implications for SHAJ and Somali based research for health.
The study raises concerns about the scarcity of research publications on Somali public health issues. This points to the need for research capacity strengthening in general and with special attention to the important role of the newly established Somali universities. We note a lack of balance regarding the topics and public health relevance of published papers in relation to the burden of prevailing health problems which calls for efforts to set research priorities in tune with the broad needs of the communities. Another observation is that the papers reviewed indicate a heavy dependence of the research agenda on external organisations and funders, which calls for active attention to research ownership issues in terms of Somali leadership and authorship. There is a lack of dissemination channels for Somali based health research and limited possibilities for young Somali scientists to publish their studies. As a Somali-owned journal, we envisage that SHAJ can play a catalytic role in the promotion and dissemination of "Essential Somali Health Research".
Sorption of cobalt and zinc from single and binary metal solutions by Evernia prunastri
Authors: Pipíška Martin , Horník Miroslav , Vrtoch Ľuboš , Šnirclová Soňa , Augustín Jozef
Published: January 2022

Non-living lichen Evernia prunastri was studied as biosorbent material for zinc and cobalt removal from single and binary metal solutions. Sorption equilibrium of Zn2+ and Co2+ ions was reached within 1 hour. Both cobalt and zinc biosorption was not pH dependent within the range pH 4-6 and negligible at pH 2. The experimental results were fitted to the Langmuir, Freundlich, Redlich-Peterson and Langmuir-Freundlich adsorption isotherms to obtain the characteristic parameters of each model. The Langmuir, Redlich-Peterson and Langmuir-Freundlich isotherms were found to well represent the measured sorption data. According to the evaluation using the Langmuir equation, the maximum sorption capacities of metal ions onto lichen biomass were 112 μmol/g Zn and 97.2 μmol/g Co from single metal solutions. E. prunastri exhibited preferential uptake of zinc from equimolar binary Zn2+ - Co2+ mixtures within the range 50 – 4000 μM. Even thought mutual interference was seen in all Co-Zn binary systems. To evaluate the two-metal sorption system, simple curves had to be replaced by three-dimensional sorption surface. These results can be used to elucidate the behavior of lichens as bioindicators of cobalt and zinc pollution in water and terrestrial ecosystems.

Published: January 2022

Tobacco has previously been used in investigations of metals and radionuclide uptake. This study presents determination of bioaccumulation and translocation of 60Co2+ ions in tobacco plants (Nicotiana tabacum L.) grown in Hoagland’s nutrient solution. Cobalt concentration in tobacco plants increased with increasing concentration in nutrient solution. Bioaccumulation from the initial concentration C0 = 0.96 μM Co reached 90% after 7 day cultivation. Only small amounts of Co accumulated in roots, up to 2 - 4 % were removable from roots by washing with 0.1 M CoCl2, indicating that this portion of Co is bound to the root surface in ion-exchangeable form. Tobacco roots retained approximately 2/3 of accumulated cobalt and 1/3 was transported to shoots. Autoradiography revealed that 60Co was preferentially localized in younger leaves. Prolongation of cultivation time did not change the [Co]roots : [Co]shoots ratio significantly. Relationships between growth rate, transpiration rate, uptake and distribution of cobalt in plant tissue are discussed.

Książka Dawida Głowni Początki kina w Japonii na tle przemian społeczno-politycznych kraju (2020) przedstawia szczegółowo narodziny kinematografii japońskiej – od sprowadzenia aparatury filmowej w 1897 r. i założenia pierwszych wielkich przedsiębiorstw, takich jak Nikkatsu, po początki cenzury filmowej, ustanowionej w wyniku „skandalu Zigomarowskiego” z 1912 r. Autor ukazuje kontekst społeczny, polityczny i kulturalny powstania kina w Japonii, odnosząc się m.in. do świata ulicznych rozrywek (misemono), do których początkowo zaliczano kinematograf, a także wojny rosyjsko-japońskiej, wydarzenia stymulującego rozwój branży filmowej. Szczegółowo omówiono także genezę benshi – narratorów komentujących pokazy wczesnych filmów. Procesy opisane przez Dawida Głownię zostały zestawione z narodzinami kina na ziemiach polskich na przełomie XIX i XX w.
Nerwowy uśmiech Meduzy. Tożsamości rodzicielskie w pierwszym sezonie serialu „Wychowane przez wilki”
Authors: Szewczyk Matylda
Published: January 2022

Artykuł jest analizą pierwszego sezonu serialu HBO Max Wychowane przez wilki (Raised by Wolves, prod. Aaron Guzikowski, 2020) w kontekście sposobu przedstawienia tożsamości rodzicielskich. Autorka koncentruje się na sposobie ukazania rodziny i postaci matki (centralnej w opowiadanej historii) oraz problemie reprodukcji i jej wpisania w konstrukcję fikcyjnego, serialowego uniwersum. Badając wytwarzane w serialu (i przez niego) wyobrażenia, zwraca uwagę na ich zakorzenienie we wcześniejszych, XX-wiecznych wizjach rodziny, kobiecości, macierzyństwa, nauki i technologii. Analiza serialu pozwala zaobserwować przemiany niegdysiejszych projektów emancypacyjnych (szczególnie tych związanych z feminizmem) oraz sposób, w jaki popularna narracja science fiction oddaje współczesną wrażliwość związaną z wyobrażeniami rodzicielstwa i jego roli społecznej.

In the review the author analyses Ewa Mazierska’s book Polish Popular Music on Screen (2020), which investigates the mutually entangled histories of Polish politics, cinema, TV, and music. Although it focuses on the Polish context, the general and theoretical observations that emerge from Mazierska’s analysis relate also to the broader former socialist Europe. Departing from Mazierska’s work, the author tackles the question of “(in)authenticity” in relation to popular culture. The word “authenticity” often appears in the text to express the critics’ opinions of cultural products, but it is not clearly defined. The review of Mazierska’s research starts with a preliminary analysis of the concept, which enables a transversal discussion of the data presented in the text. Then the author draws some conclusions about the current state of research on Eastern European culture by highlighting the limits and the potentials of the field.
International aspects of the disintegration of the Socialist Federal Republic of Yugoslavia
Authors: Szczesio Sławomir L.
Published: January 2022

This article analyses the international conditions during the disintegration of the Socialist Federal Republic of Yugoslavia. It is an outline of a broad research problem, a historical analysis from the perspective of the decades-long evolution of Yugoslavia’s international position. After its expulsion from the Eastern Bloc in 1948, the country balanced between East and West, becoming one of the founders and leaders of the Non-Aligned Movement. The author focuses on the aspect of Yugoslavia’s role in the politics of the West, especially the US and the EEC, during and at the end of the Cold War. It was the West that could, possibly, have played a role in preventing the disintegration of the country in the early 1990s, in contrast to the USSR, which had its own internal problems at that time. What factors influenced Western support for the SFRY during the Cold War? How did Yugoslavia’s position in Western politics change when the Cold War rivalry ended? The author points out the temporal connection between the disintegration of the SFRY and, among other things, the collapse of the Eastern Bloc and the Soviet Union, the democratisation process in Eastern Europe, German reunification, European integration, and the crisis in the Middle East. In the end, there was a lack of real and coherent action by Western countries to bring about a peaceful solution to the crisis in the Balkans. The consequence of this would be the disintegration of the SFRY and several years of war in the former Yugoslavia.
Vukovar – memory conflicts as an obstacle to Serbo-Croatian reconciliation
Authors: Rekść Magdalena
Published: January 2022

30 years after the tragic events in Vukovar, the Serb and Croatian communities live side by side, each cultivating their memory of their own tragedy and their own victims. The peaceful reintegration, that Croats are proud of, did not go hand in hand with building an atmosphere of reconciliation. No wonder then, that Vukovar is a model example of a divided city, where the mental divisions and psychological barriers affect its politics and everyday life. It seems that such a situation is favourable to politicians in Belgrade and Zagreb. One gets the impression that, as in 1991, Vukovar is becoming a victim of great politics and the clash of Serbian and Croatian nationalism.

Jednym z kluczowych obszarów bezpieczeństwa państwa jest bezwzględnie bezpieczeństwo militarne. Jego zapewnienie wymaga szeregu różnorodnych działań o charakterze polityczno-militarnym, wśród których istotna rola przypada na realizację zdolności w obszarze państwa-gospodarza (HNS) dla przemieszczania sił i środków wojsk sojuszniczych na terytorium kraju. Wypełnienie zadań wynikających z obowiązków HNS jest istotne z punktu widzenia obronności kraju, ale także jego postrzegania na arenie międzynarodowej. Jedną z ważniejszych w tym zakresie kwestii jest udostępnianie rejonów, zabezpieczenie materiałowe i techniczne oraz infrastruktury na potrzeby ześrodkowania i zakwaterowania wojsk, co jest realizowane w oparciu o szereg inwestycji infrastrukturalnych. Z perspektywy współczesnych uwarunkowań rozbudowa i utrzymanie właściwej infrastruktury transportowej, przed wszystkim drogowej, wszystkich gałęzi transportu jest niezbędna dla zapewnienia wymaganych warunków przemieszczania się osób oraz przewozu uzbrojenia i sprzętu wojskowego, wparcia wojsk sojuszniczych, w przypadku pokoju, kryzysu lub wojny. Nowoczesna infrastruktura transportowa - drogowa, umożliwia rozwój polskiej gospodarki i wzmacnia jej powiązanie z gospodarką światową. Jest także ważnym składnikiem bezpieczeństwa w systemie obronnym państwa oraz terytorialnie zrównoważonego rozwoju kraju w obszarze inwestycyjnym. Systematyczna poprawa infrastruktury transportowej - drogowej stanowi jedno z podstawowych wyzwań dla rozwoju państwa nie tylko z perspektywy gospodarczej, ale także odgrywa priorytetową rolę w odniesieniu do bezpieczeństwa i obronności państwa oraz naszych zobowiązań sojuszniczych.
