O potrzebie umiaru w kulturze nadmiaru
Authors: Smółka Lucyna
Published: October 2021

CEL NAUKOWY: Celem artykułu jest konceptualizacja cnoty umiarkowania, wskazanie konsekwencji zaniedbania tej sprawności moralnej w kulturze konsumpcji, wyeksponowanie współczesnej etyki cnoty jako perspektywy rozważań nad konsumpcją etyczną.
PROBLEM I METODY BADAWCZE: Przedstawiony problem badawczy dotyczy odpowiedzi na pytania: Czym jest umiarkowanie? Jak brak umiaru w kulturze konsumpcyjnej wpływa na życie ludzi? Jakich praktycznych wskazówek w kwestii etycznej konsumpcji może dostarczyć nam współczesna etyka cnót? Zastosowano metodę analityczno-syntetyczną literatury przedmiotu.
PROCES WYWODU: Na podstawie opracowań naukowych dokonano charakterystyki cnoty umiarkowania, przedstawiono, jak brak umiaru ujawnia się w społeczeństwie konsumpcyjnym i jakie są tego konsekwencje dla rozwoju człowieka. Wykazano użyteczność etyki cnoty dla refleksji nad kształtowaniem cech odpowiedzialnego konsumenta.
WYNIKI ANALIZY NAUKOWEJ: Z przeprowadzonych analiz wynika, że umiarkowanie to cnota kontrowersyjna, nie przez wszystkich akceptowana, mimo jej niewątpliwych walorów. Szczególne niezrozumienie dla niej wykazuje społeczeństwo konsumpcyjne, które płaci za to wysoką cenę. Konieczny jest zwrot ku wartościom, które muszą być urzeczywistniane w konkretnych czynach, czyli działaniach człowieka cnotliwego.
WNIOSKI, INNOWACJE, REKOMENDACJE: Każdy, aby móc realizować się w człowieczeństwie, potrzebuje umiarkowania. Kierowanie się nim jest szczególnie trudne w dobie kultury konsumpcyjnej, gdzie cnotą stało się nabywanie i konsumowanie. Warto pomagać, zwłaszcza młodym, zrozumieć zależności między rozwojem własnym a przejawianymi zachowaniami konsumenckimi. Kluczowa jest zwłaszcza praca na swoim charakterem.
IMINATION OF CHITOSAN NANOFIBERS IN A HETEROGENEOUS SYSTEM. SYNTHESIS OPTIMIZATION AND IMPACT ON FIBER MORPHOLOGY
Authors: ANISIEI ALEXANDRU , BOSTANARU ANDRA-CRISTINA , MARES MIHAI , MARIN LUMINITA
Published: October 2021

The paper aimed to prepare imino-chitosan fibers by the imination reaction in a heterogenous system, targeting the improvement of anti-pathogenic activity. To this end, porous neat chitosan fibers were prepared by electrospinning of the polyethylene glycol/chitosan blend, followed by polyethylene glycol removal. Imination of the neat chitosan fibers was carried out in three liquid phase systems using solvents of different polarity and, consequently, different ability to swell the solid phase chitosan fibers. The successful imination was qualitatively and quantitatively assessed by FTIR and 1H-NMR spectroscopy, and the impact of the liquid phase on the fibers’ morphology was evaluated by SEM, POM and AFM microscopy. Further, the antimicrobial activity of the imino-chitosan fibers was investigated on relevant bacterial and fungal strains. It was concluded that the prior swelling in water of the fibers improved the imination degree, while the use of a less polar solvent, such as toluene, favored the preservation of the fibrous morphology. The imination with an antimicrobial aldehyde endowed the chitosan fibers with the ability to create a physical barrier against pathogens.

Cellulases are known to convert cellulose into monomeric or dimeric structures, hence playing an important role in bioethanol production, along with their applications in textile and paper industries. This study was directed towards the isolation and screening of cellulase producing bacteria from different soil samples on CMC (carboxymethyl cellulose) agar plates, followed by Gram’s iodine staining. Six strains showed clear zones of hydrolysis on CMC agar plates. Isolates were identified as Bacillus megaterium, Pseudomonas stutzeri, Bacillus aerius, Bacillus paralichniformis, Bacillus flexus, and Bacillus wiedmanni by 16S rRNA gene sequencing. These strains were cultivated by submerged fermentation for cellulase production using various lignocellulosic wastes, such as corn cob, rice husk, wheat straw, seed pods of Bombax ceiba and eucalyptus leaves. Results showed that Pseudomonas stutzeri is the best cellulase producer among these strains. It offered the highest cellulase activity of 170.9±4.1 (IU/mL/min) in media containing eucalyptus leaves after 24 h of incubation at 37 °C, followed by Bacillus paralichniformis, Bacillus wiedmanni, Bacillus flexus, Bacillus aerius and Bacillus megaterium. These bacterial strains and lignocellulosic wastes could be potentially used for industrial exploitation, particularly in biofuels and textiles.

Published: October 2021

In this work, a commercial cellulolytic cocktail was immobilized on glutaraldehyde activated chitosan gel. The chitosan concentration in the gel preparation, pH, immobilization time and enzymatic loading were evaluated. Immobilized cellulases showed better hydrolysis performance when an enzyme loading of 134 mg protein/g carrier was used for immobilization at pH 9.0 for 30 minutes. Hydrolysates with a glucose content of 13.43 and 10.35 g/L were obtained when Avicel and pretreated sugarcane bagasse were used as substrate, respectively. Immobilized cellulase lost 60% of its hydrolysis performance after 8 cycles using Avicel, and 75% after 6 cycles for sugarcane bagasse. The hydrolysis performance associated with the reuse of the immobilized cellulases indicates that an improvement in the immobilization of cellulases, coupled with an improvement in the pretreatment of lignocellulosic biomass, will allow the development of a continuous hydrolysis system with the enzyme retained in the reactor.

The aim of the study has been to develop a biodegradable film from marine polysaccharides. The optimization of polysaccharides quantity for the composite film was sought by empirical response surface methodology. The Box–Behnken Model Design was applied to optimize the concentration of chitosan (1.0-2.0% (w/v), agar (1.0-2.0% (w/v) and glycerol (0.1-0.5% (w/v) as independent variables to achieve the goal. The overall desirability function fits with the quadratic model (0.862043) at a significant level (p < 0.05) for the optimum concentration of chitosan (1.5% (w/v), agar (2.0% (w/v) and glycerol (0.41% (w/v) to obtain the minimum water vapor permeability (7.25 10-10g m m-2 Pa-1 s-1) and maximum tensile strength (12.21 Ma P), elongation at break (7.32%) and puncture resistance (16.18 N) in the optimized composite film. The absolute residual errors of experimental and predicted responses were between 1.24 and 3.56% acceptable levels. Attenuated total reflection–Fourier transform infrared spectroscopy confirmed the intermolecular non-covalent hydrogen bond between the hydroxyl groups of agar and glycerol with the amino group of chitosan. 3D atomic force microscopy images revealed that the chitosan, agar and glycerol film has layer-by-layer smooth surface properties due to homogenous interaction among the polysaccharides; this provides the film with good mechanical properties and with functional application. Chitosan was found to be responsible for the lower level of water vapor permeability and higher puncture resistance of the film. Tensile strength and elongation at break were influenced by agar and glycerol. The whiteness of the film was negatively affected with the concentration of chitosan.

High-intensity focused ultrasound causes thermal coagulation around the focal area in a minimally invasive manner. Multiple sonication is required to treat the target area due to the small size of the focal area. Consequently, the throughput is limited, and several sonication paths have been proposed to improve it. However, a systematic comparison of these paths is lacking. In this study, the effect of the moving focal area was analyzed using a moving heat source model. The effects of moving the heat source and the utilization of thermal accumulation were evaluated for the proposed sonication paths. Controlling multiple foci was effective because the heat flux was concentrated on energy that was focused in the unprocessed area without providing energy to previously processed areas. The multiple foci using thermal accumulation could reduce the treatment time and total input energy by 7.7% and 50%, respectively, compared to methods without thermal accumulation.

Food Motivational Factors of Tourists to Greece
Authors: Lazaridis Georgios , Mavrommatis George , Matalas Antonia
Published: October 2021

Despite the fact that tourism is one of Greece's economic pillars and that food can lead to greater satisfaction and loyalty to the destination, little research effort has been devoted to understanding tourists' food consumption complexities. In response, this study aimed at investigating
the themes behind the food motivations of international tourists to Greece. A qualitative approach was deployed by implementing semistructured interviews among tourists (N = 28), and a thematic analysis was conducted in order to categorize interviewees' statements into eight themes:
local culture learning, authentic experience, novelty seeking, social interactions, sensory pleasure, health concerns, familiar food, and the need for sustenance. These motivations were heterogeneous and exerted significant influence over food choices and eating behavior. Even though Greek
destinations attract tourists primarily seeking journey-related food elements, other secondary motivations involving travel intentions independent of local gastronomy should not be neglected. Although the factors identified may not be exhaustive, this study provides a clear model for further
research concerning tourists' food motivational factors in Greece and other Mediterranean destinations.
Estucado mediante películas de Beva® Artist Gesso-P: aplicación en un óleo sobre lienzo de Jacob Van Ruysdael
Authors: García Fernández-Villa Silvia
Published: October 2021

El presente trabajo aborda la metodología desarrollada para un complejo caso de estucado planteado en una pintura de Jacob Van Ruysdael (1628–1682). El óleo sobre lienzo presentaba inicialmente una topografía característica que necesariamente debía ser replicada en los estucos, si bien los contornos sumamente irregulares de las lagunas dificultaban su texturización. El sistema desarrollado se basa en el empleo un laminado pre-impreso conformado por una capa de soporte e intervención de TNT de poliéster y Beva® Artist Gesso-P moldeado mediante mini-mesa de baja presión. Para la adaptación completa a los contornos de las lagunas se ha empleado el escaneado directo de las zonas y posterior impresión de los contornos a escala 1:1 sobre el soporte del laminado. Mediante esta sistemática se ha obtenido un estucado perfectamente integrado en la topografía original y completamente reversible. Por otra parte, se trata de una metodología que permite obtener una óptima reproducción de las texturas e integración en los contornos más complejos, y que puede ser aplicada con éxito a otras obras con requerimientos similares.

Authors: Lima Gularte Débora , Novello Tanise Paula
Published: October 2021

A través de las inquietudes y preguntas sobre el aprendizaje matemático, el presente trabajo tiene como objetivo presentar un estudio sobre la conceptualización de las Matemáticas a través de situaciones problemáticas basado en la Teoría de los Campos Conceptuales, de Gérard Vergnaud. Dicha teoría propone estudiar cómo ocurre el aprendizaje de conceptos, es decir, comprender cómo se desarrolla el sistema cognitivo y cómo se aprenden habilidades más complejas. Así, el objetivo de este estudio es investigar a un colectivo de alumnos de 7º año de Educación Primaria que comprendan los conceptos de la matemática a partir de situaciones problemáticas basadas en la Teoría de Campos Conceptuales (CBT). Para ello, se crearon situaciones problemáticas involucrando ecuaciones de primer grado vinculadas a actividades específicas y contextualizadas que trajeron, además del concepto abordado, la conciencia del consumo de energía eléctrica. Finalmente, se espera que esta investigación sea un punto de partida para una investigación más profunda de la conceptualización matemática, a partir de la Teoría de Campos Conceptuales, que ofrece un aporte enriquecedor para la comprensión del desarrollo y aprendizaje de habilidades.

ARQUEGENEALOGÍA FOUCAULTIANA EN LA ENSEÑANZA DE HISTORIA: EL DISCURSO NEGATIVO DE EXTREMA DERECHA BRASILEÑA SOBRE LA DICTADURA MILITAR DE BRASIL EN UNA PROPUESTA DIDÁCTICA
Authors: Sousa Alves Alison Sullivan de , Vieira da Silva Francisco
Published: October 2021

El objetivo de este trabajo consiste en organizar una propuesta didáctica para la enseñanza de Historia, a partir del análisis de narrativas negacionistas de la extrema derecha brasileña sobre la Dictadura Militar de Brasil. Para ello, partimos de las reflexiones de los estudios discursivos de Foucault, a través de las nociones de discurso, enunciado, formación discursiva y voluntad de verdad. Sobre la metodología, vale destacar que se trata de un estudio descriptivo-cualitativo, cuyo abordaje sigue un sesgo predominantemente cualitativo. La posibilidad de problematizar los objetos de conocimiento de la Historia en la educación básica, mediante la arquegenealogía, se mostró viable y posible, en la medida que potencializamos el análisis del discurso negacionista de la extrema derecha sobre la Dictadura Militar de Brasil, en una propuesta didáctica, que nos ayudó a sintetizar las materialidades discursivas, con vistas a problematizar, en el aula, enunciados que suscitan ciertas "voluntades de verdad" acerca de la dictadura militar en los dichos del actual escenario sociopolítico brasileño.

An innovative approach for the design of air electrodes for metal–air batteries are free-standing scaffolds made of electrospun polyacrylonitrile fibres. In this study, cobalt-decorated fibres are prepared, and the influence of carbonisation temperature on the resulting particle decoration, as well as on fibre structure and morphology is discussed. Scanning electron microscopy, Raman spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, elemental analysis, and inductively coupled plasma optical emission spectrometry are used for characterisation. The modified fibre system is compared to a benchmark system without cobalt additives. Cobalt is known to catalyse the formation of graphite in carbonaceous materials at elevated temperatures. As a result of cobalt migration in the material the resulting overall morphology is that of turbostratic carbon. Nitrogen removal and nitrogen-type distribution are enhanced by the cobalt additives. At lower carbonisation temperatures cobalt is distributed over the surface of the fibres, whereas at high carbonisation temperatures it forms particles with diameters up to 300 nm. Free-standing, current-collector-free electrodes assembled from carbonised cobalt-decorated fibre mats display promising performance for the oxygen reduction reaction in aqueous alkaline media. High current densities at an overpotential of 100 mV and low overpotentials at current densities of 333 μA·cm−2were found for all electrodes made from cobalt-decorated fibre mats carbonised at temperatures between 800 and 1000 °C.
Achievements and perspectives of development of Eastern Slavonic explanatory linguistic terminography
Authors: Shcherbin Vyacheslav
Published: October 2021

The most complete explanatory dictionaries of linguistic terminology published in Eastern Slavonic countries are considered in the article. The comparative analysis of index, micro-, macro-, and megastructural characteristics of the most complete Russian, Ukrainian, and Belarusian dictionaries of linguistic terms (by O.S. Akhmanova, M.G. Bulakhov, and A.A. Zagnitko) is conducted. The forecast is made about perspectives and possible ways of development of Eastern Slavonic explanatory linguistic terminography. The conclusion is substantiated that a much higher informational level of analysis of the metalanguages of Russian, Ukrainian and Belarusian linguistics can be reached only if a combined explanatory dictionary of Eastern Slavic linguistic terminology is created by mutual efforts of the linguists, lexicographers and terminologists of Russia, Ukraine, and Belarus.
In its turn, the unresolved problems of the modern Eastern Slavonic explanatory linguistic terminography should include the following issues:
1) there is a clearly insufficient level of institutionalization of the terminography activity in some Eastern Slavonic countries (in Belarus, for example, until now, there are no specialized centers, departments and periodicals whose main purpose would be studying, systematizing and dictionary-coding scientific terminology revealed as a result of analysis of scientific and specialized texts);
2) drafting of the Eastern Slavonic explanatory linguistic terminography products shows certain negative trends (many terminological and encyclopedic dictionaries and reference books lack alphabetic and subject-specific indexes of 12 terms that are much-needed for the readers; a number of terminological dictionaries on linguistics are clearly compilations).
In addition, there is a vital need for the Eastern Slavonic linguistic terminologists to cooperate with the subject-specialists in the different branches of modern linguistics as actively as possible to address the topical issues of the current terminography practices. If this closest union of terminologists and subjectspecialists in the different branches of modern linguistics is not be established in the nearest future, then, apparently, terminography and the science of terminology will stop coordinating their professional efforts with the general science of philology soon, and further development of these cross-cutting disciplines will go its own way as this is already going on in some countries of the West.
Identifying the reasons for understimation of Russian companies at primary placement of shares

Первичное публичное предложение (IPO) предполагает новые финансовые возможности для компании-эмитента, такие как: получение доступа к рынкам капитала, расширение базы инвесторов, повышение рыночной стоимости компании. В большинстве первичных размещений существует недооценка компаний, выходящих на рынок, что может быть связано с влиянием как внешних, так и внутренних факторов. Цель исследования состоит в выявлении факторов, влияющих на первичную недооценку российских компаний при IPO на внутренних и внешних площадках. Новизна научного исследования заключается в комплексном анализе факторов, оказывающих влияние на недооценку акций высокотехнологичных компаний при первичном размещении. Наряду с ранее изученными факторами (рыночная конъюнктура, волатильности ценового диапазона акций относительно среднего значения, рентабельность активов компании-эмитента за год, предшествующий первичному размещению), исследование дополнено оценкой влияния таких факторов, как выбор принадлежности рынка размещения акций к российским или зарубежным площадкам, влияние выбора нескольких площадок размещения, престижность и репутация андеррайтера, принадлежность компаний к высокотехнологичным отраслям. В данном исследовании престижность андеррайтера будет определена принадлежностью к «Большой четверке», что может являться дополнительным фактором перспективности и успешности выхода на рынок акций. По результатам проведенного исследования было определено, что на величину недооценки российских компаний при размещении на внутреннем рынке оказывают воздействие такие факторы, как принадлежность к высокотехнологичной отрасли, и показатель, характеризующий состояние фондового рынка. В то время как при проведении IPO на иностранных фондовых рынках значимыми факторами являются отраслевая принадлежность, цена размещения. Показатели престижности андеррайтера, размещения на нескольких площадках, рентабельности активов и ширины ценового диапазона оказались не значимыми по результатам исследования.

The purpose of the regulations is to ensure protection of human life and health and of the environment of facilities. In this article the general industrial safety authority as one of the pillars of the authority’s tasks is presented, as well as the relevant legal provisions with regard to the scope constraints.
Incorporation of Human Rights in International Relations
Authors: Oikya Upal Aditya
Published: October 2021

Human rights have been firmly enmeshed in both studies and practice of international relations. The prevailing theories of international relations describe the function of those rights in substantially dissimilar ways, and it is apparent that their key statements include compelling arguments, suggesting an inconvenient apposition of state sovereignty with ideas of universal moral order. The development of the universal human rights regime of the United Nations (UN), the growth of international non-governmental organizations (NGOs), and, eventually, human rights activists have made it possible for human rights to be more deeply incorporated into state diplomatic activities.  These trends, however, raise critical concerns about the practice of the state of human rights. Although there is some reversal of the norm, however, states continue to face humanitarian crises and show signs of human rights protection domestically and promotion internationally to varying degrees. In the same way, we are also seeing a major change in the principles and procedures of international enforcement of human rights. The goal of this paper is to address briefly certain variables relevant to the incorporation of human rights in international relations.
Radical decrease in the number of homicides in Hungary
Authors: Sivadó Máté
Published: October 2021

In Hungary, the number of crimes recorded by crime statistics is surprisingly decreasing. Since its peak in 1998, the overall crime rate has fallen to less than a third. Within this, the decline in the number of homicides, which fell to one-fifth, is even more pronounced. Many people critically look at statistical indicators, and the authority’s accounting methods know the superior numbers. In my research, I examined this.
Cosmic Web-halo Connection between Twin Universes

Both simulation and observational data have shown that the spin and shape of dark matter halos are correlated with their nearby large-scale environment. As structure formation on different scales is strongly coupled, it is tricky to disentangle the formation of a halo from that of the large-scale environment, making it difficult to infer which is the driving force behind the correlation between halo spin/shape and the large-scale structure. In this paper, we use N-body simulations to produce twin universes that share the same initial conditions on small scales but that are different on large scales. This is achieved by changing the random seeds for the phase of those k modes smaller than a given scale in the initial conditions. In this way, we are able to disentangle the formation of halo and large-scale structure, making it possible to investigate how halo spin and shape correspond to the change of environment on large scales. We identify matching halo pairs in the twin simulations as those sharing the maximum number of identical particles within them. Using these matched halo pairs, we study the cross match of halo spin and the correlation with the large-scale structure. It is found that when the large-scale environment changes (eigenvector) between the twin simulations, the halo spin has to rotate accordingly, although not significantly, to maintain the universal correlation seen in each simulation. Our results suggest that the large-scale structure is the main factor to drive the correlation between halo properties and their environment.
