ancestros Mayas en las mallas cosmopolíticas del período clásico
Authors: Pacheco Daniel Grecco , Iwaniszewski Stanislaw
Published: December 2021

Este estudio discute la presencia de importantes ancestros en las mallas cosmopolíticas mayas del período clásico en las tierras bajas. Presentaremos el papel de estos personajes en la constitución de la persona social de los gobernantes, y en la conducción política de importantes eventos de las sociedades mayas de aquel momento. Con el uso de los conceptos de mallas ontológicas relacionales y cosmopolítica, proponemos la existencia de un gran enmarañado de relaciones cosmopolíticas presente en las ciudades mayas, en el cual los ancestros tenían un papel protagonista y convivían lado a lado con sus herederos, lo que anulaba la muerte biológica de aquellos actores. Con eso, discutiremos de qué manera tales mallas eran establecidas y qué tipos de relaciones sociales eran creadas por estos diferentes actores.
Palmeira e pedra desenterrados

Published: December 2021

O artigo recolhe resultados de investigações arqueológicas sobre uma igreja construída inicialmente para celebrar o nascimento de Jesus vistos como capazes de problematizar a visão tradicional a respeito das origens do islã e da formação do Corão. Procura avançar para além do que a este respeito já foi sugerido, apontando possibilidades, advindas da conexão entre resultados da pesquisa arqueológica e dos estudos sobre textos constitutivos do livro sagrado muçulmano, para repensar o complexo cenário sociorreligioso no Sudoeste asiático nos tempos da Antiguidade tardia.
mapa cultual romano
Authors: Dourado Guerra Danilo
Published: December 2021

Objetiva-se explorar alguns traços significativos do mapa cultual romano. Este se configura no âmbito de uma complexa fenomenologia do culto, e se delineia a partir de uma aglutinação de diferentes elementos que constituem seu contorno. Situado no vértice piramidal do processo de construção do divino César e forjado sob uma plataforma teopolítica de plausibilidade, o culto ao imperador consuma-se como o ápice dos rituais de apoteose, o topo da dinâmica de construção do devoto e, sobretudo, o zênite da construção simbólico imagética da face sagrada do Estado romano. Na dinâmica do espetáculo, como em um grand finale, esse sistema ritual se estabelece no signo praxiológico da teatrocracia em Roma.

Published: December 2021

Introdução: O nascimento de um filho com deficiência pode alterar rotinas e influenciar no processo de adaptação dos pais, por se caracterizar como um acontecimento não esperado. Ainda pode produzir nos progenitores sentimentos semelhantes aos vivenciados em um processo de luto. Objetivo: Analisar a relação entre a adaptação parental à filha com cegueira congênita e disfagia, relacionadas à prematuridade extrema, e seu possível impacto no processo de adesão às orientações terapêuticas sobre a alimentação da criança. Método: Trata-se de um estudo de caso de cunho qualitativo. Foi realizada uma análise da adaptação parental à deficiência, e avaliações fonoaudiológicas da linguagem e da disfagia. Resultados: A avaliação fonoaudiológica evidenciou disfagia para líquidos finos e ausência de alterações de linguagem. A restrição alimentar tornou-se evidente a partir da dificuldade parental em aceitar e seguir as orientações quanto à consistência alimentar. A análise dos dados de adaptação parental à deficiência da filha sugere que essa dificuldade esteve relacionada à aceitação da cegueira e da disfagia. A emergência de restrição alimentar esteve relacionada às dificuldades na aceitação das orientações fonoaudiológicas por parte dos pais, considerando a disfagia para líquidos finos. Essas dificuldades encontram um correlato na análise da adaptação parental do pai e da mãe. Conclusão: Evidencia-se a importância do acompanhamento por uma equipe interdisciplinar.
Voz e Ensino a distância (EaD)
Authors: Ferraz Pablo Rodrigo Rocha , Ferreira Leslie Piccolotto
Published: December 2021

Ao longo dos anos o entendimento de que o professor sofre limitações vocais quanto à qualidade e eficiência vocal tem sido ampliado de maneira constante. Questões além dos aspectos da qualidade vocal, queixas e sintomas se somam a importante influência que o trabalho tem na saúde do professor, condicionada também por fatores sociais, econômicos, tecnológicos e organizacionais. Paralelamente, há alguns anos, estudos com o professor universitário vem ganhando espaço, pois, observa-se que o setor da educação de ensino superior, no seu processo de reestruturação e adequação ao novo cenário socioeconômico e de produção da ciência, tecnologia e inovação, gera novas demandas que implicam transformações na organização do trabalho desse profissional. Dessa forma, a presente comunicação tem como objetivo apresentar uma proposta de curso para o professor universitário na modalidade ensino a distância (EaD), como uma ferramenta de sensibilização quanto às questões da saúde vocal, orientação e conscientização de mudanças de hábitos e promoção de estratégias para adequação do ambiente e da organização do trabalho que favoreçam a melhora da qualidade de vida. Organizado como comunicação assíncrona, o curso possui uma carga-horária total de 30 horas, e é dividido em seis módulos: 1 – A voz e suas características; 2 – Voz e trabalho; 3 – Voz e corpo; 4 – Voz e seus cuidados; 5 – Técnicas vocais e 6 – Estratégias comunicativas de expressividade.
Dupla Jornada no imaginário de universitárias conforme a Psicologia Psicanalítica Concreta
Authors: Risquioto Batoni Bruna , De Almeida Schulte Andréia , Gallo Belluzzo Sueli Regina , Aiello-Vaisberg Tânia Maria José
Published: December 2021

Considerando que o acúmulo de atividades profissionais e tarefas domésticas onera o cotidiano das mulheres, provocando sofrimento emocional, o presente estudo objetiva investigar o imaginário coletivo de universitárias sobre a dupla jornada feminina na perspectiva da psicologia psicanalítica concreta. Organizado como pesquisa qualitativa com o método psicanalítico, é articulado através de entrevista psicológica coletiva, mediada pelo uso do Procedimento Desenho-Estória com Tema. A consideração psicanalítica do material permitiu a interpretação de um campo de sentido afetivo-emocional denominado “Meu dinheiro, meu conforto e minha diversão”. A prevalência desse campo não deixa espaço imaginativo para a valorização de outros projetos de vida, como engajamento em trabalho profissional pessoal e/ou socialmente significativo e constituição de família. O quadro geral permite afirmar que as participantes imaginam que é possível escapar da dupla jornada evitando dependência financeira – um dos mais importantes meios de opressão feminina –, e cultivando posicionamentos voltados para a satisfação das próprias necessidades.

Полученные выводы имеют прикладное значение и могут быть использованы при определении стратегий развития школьной инфраструктуры.

Typical architecture and design of school spaces is often not related to its pedagogical concept and does not reflect the identity of the teaching staff and students. In this regard, there is a request to involve participants of educational relations in the design and development of an educational environment in which the capabilities of teachers and students would be most fully revealed. The relevance of the article lies in the emergence of new and various projects of redesign and renovation of the educational environment, expanding the understanding of the functional capabilities of the spaces of educational organizations, demonstrating the educational and social potential of new spaces of educational organizations. The article summarizes the experience of organizing and holding the City Festival of Infrastructure Solutions of the Moscow City University as one of the ways that can be used to attract teams of educational organizations to the topic of large-scale changes in educational infrastructure. On the Festival it were identified and presented the best practices of infrastructure solutions for the effective use of the space of educational organizations in the city of Moscow, implementing general educational programs of preschool education, primary general education, basic general education and secondary general education. Festival participants gained experience and inspiration in changing the school space, and learned about modern finishing materials and equipment for schools. The conclusions drawn by the authors have the practical importance and can be used to determine strategies for the development of school infrastructure.

Authors: Li Qiujie , Zhou Xuehan , Bostian Brad , Xu Di
Published: December 2021

With the rapid growth of online learning at community colleges and the low course completion and performance associated with it, there has been increasing need to identify effective ways to address the challenges in online teaching and learning at this setting. Based on open-ended survey responses from 105 instructors and 365 students from multiple community colleges in a state, this study examined instructors’ and students’ perceptions of effective and ineffective instructional practices and changes needed in online coursework. By combining structural topic modelling techniques with human coding, we identified instructional practices that were perceived by both instructors and students as effective in supporting online learning as well as ineffective and needing improvement. Moreover, we identified a handful of misalignments between instructors and students in their perceptions of online teaching, including course workload and effective ways to communicate.
Teaching Presence in Online Courses: Similar Perceptions but Different Experiences from Multiple Instructor Perspectives
Authors: Turk Murat , Muftuoglu Ali Ceyhun , Toraman Sinem
Published: December 2021

Online course instructors’ perceptions and perspectives regarding their teaching presence as a key presence in online learning environments significantly influence, if not determine, their online teaching practices, which in turn influence the quality of online students’ learning experiences. Although gaining deeper insights into online course instructors’ perceptions and experiences of teaching presence is quite important and valuable for online education, there is still limited qualitative inquiry into this critical presence across diverse online teaching contexts. The purpose in this qualitative, multiple case study was to explore and understand online course instructors’ perceptions and experiences regarding their own presence in their online courses. We explored the perceptions and experiences of eight course instructors teaching undergraduate and graduate-level online courses at a midwestern U.S. college. Our findings indicated that teaching presence was uniformly considered important and necessary by the instructors although their applications and priorities regarding their teaching presence varied. We discussed our themes that emerged from our interview data and offered several theoretical and practical implications regarding teaching presence in online learning environments.

Comparison of changes in the labour markets of post-communist countries with other EU member states
Authors: Dmytrów Krzysztof , Bieszk-Stolorz Beata
Published: December 2021

strengthen their international competitiveness. This was linked to the implementation of institutional and economic reforms, significant technological changes and improvements in the quality of human capital, as well as fiscal stabilisation policies. These changes affected their situation in the labour market.

Purpose of the article: The aim of the study is to assess changes in the situation in the labour market in the EU with particular emphasis on the post-communist countries in the period 2002? 2019.

Methods: The situation of countries in the European labour market was estimated using the TOPSIS method. A similarity matrix of changes in the composite variable for each country was then constructed using the Dynamic Time Warping method. On its basis, homogeneous clusters of countries were determined using the Ward?s method.

Findings & value added: Four homogenous clusters of countries were formed. The post-communist ones belonged to two groups. In one, there were two countries ? Croatia and Slovakia. The rest of the post-communist countries were in a large cluster, which also included Germany, Malta, Finland, Portugal, France and Belgium. Changes of the situation in the post-communist countries in this group improved very much during the analysed period (this was particularly evident for Czechia, Estonia and Poland). It is interesting to investigate whether the reaction of labour markets to changes in the global economic situation in post-communist countries is similar to that in the old EU countries. The similarity of changes can be measured using the DTW method. There is an empirical research gap in this respect. Therefore, the added value is the use of this method in assessing similarities of changes in the labour market situation in post-communist countries in comparison to the Western European ones.
Ecological and economic multicriteria optimization of operating alternative propulsion vehicles within the city of Ostrava in the Czech Republic
Authors: Janovská Kamila , Vozňáková Iveta , Besta Petr , Šafránek Marek
Published: December 2021

Research background: Individual car transport significantly burdens the environment, especially in the centres of large cities. There is pollution, traffic jams and an increase in overall noise. In the area of passenger car transport, legislation is being significantly tightened. Therefore, there are also increasing demands on public transport operators in the Czech Republic. Previously, most of the fleet consisted of diesel vehicles. These have been gradually replaced by drives that are significantly more environmentally friendly, such as the Compressed natural gas drive. The requirements defined in relation to the reduction of vehicle emissions are increasingly stricter. A number of cities, not only within the European Union, are addressing significant issues concerning the future of public transport. Purpose of the article: The main objective of the article is to demonstrate an in-depth analysis of the operation of transport vehicles in the Statutory City of Ostrava, both from the cost and environmental point of view. The comparison of transport means using CNG, electric and diesel propulsion is made. Specific factors such as the route profile or the environmental impact of the mode of transport are also taken into account. The extent of the data processed and the multidimensional nature of the assessment offer a unique analysis of the problem. The article provides an exact view of the advantages and disadvantages of operating specific means of transport. Everything is based on data on transport operations in the city of Ostrava (the Czech Republic, EU). Methods: The comprehensive evaluation is based on the application of methods from the field of financial accounting, evaluation of measured data from the operation of transport means and, last but not least, on the analysis of empirical data from the given area. The analysed data set is unique due to the time period, as is the multi-criteria evaluation methodology.  Findings & value added: The analysis performed demonstrated the economic viability of operating CNG vehicles. The main added value of the article is the unique multi-criteria evaluation procedure for the vehicles. The paper shows the evaluation of a complex decision problem in the transport field in the form of a case study implemented in the city of Ostrava. The evaluation results then consider both cost and environmental factors, which can be described as a comprehensive and highly innovative approach. The defined assessment can then be applied to other European and world metropolises.

Published: December 2021

Se describe el caso de un ejemplar de tortuga argentina, Chelonoidis chilensis, macho, adulto, que fue atacado y mordido por un canino. Se constató la fractura del plastrón, con pérdida del segmento frontal y exposición de los músculos deltoideus y supracoracoideus. Se fijaron 3 ganchos al plastrón mediante resina epoxi, aproximando la piel a los mismos con poliamida 0,30. Se utilizó cefazolina como tratamiento antibiótico y los espacios abiertos entre piel y plastrón fueron cubiertos con miel de abeja en forma tópica cada 48 horas. Al día 5 de tratamiento se percibió el crecimiento de Fusarium spp. en la superficie, por lo que se modificó el tratamiento local y se procedió a realizar diariamente el lavado de la zona con iodopovidona al 7,5 %, seguido de la aplicación de miel. Se realizaron baños en agua durante 2 horas, cada 48 horas.  A los 5 días del procedimiento, el paciente comenzó a ingerir agua y, a los 35, a alimentarse. A los 28 días se percibió buena adherencia de la piel a los músculos, al tiempo que, coincidentemente, empezó a utilizar los miembros anteriores. A las 6 semanas se retiraron las suturas y se constató remodelación del tegumento y cierre completo de la herida.
La historiografía en los registros de visita: fray Alonso Ponce
Authors: Escandón Patricia
Published: December 2021

Aparte de constituir informes de carácter oficial, la documentación generada por la visita del comisario franciscano Alonso Ponce (1584-1589) a su orden en Nueva España es una cala profunda en la sociedad y la estructura gubernativa finiseculares del reino. En el registro de la visita, escrito por el secretario fray Antonio de Ciudad Real, y en algunos expedientes remitidos al Consejo de Indias, tanto por el comisario como por sus enemigos, se delinean con nitidez la naturaleza de los conflictos de poder entre los altos dignatarios civiles y eclesiásticos, las alianzas y confrontaciones entre distintas agencias locales, así como el cambio de orientación en el tipo de pastoral que desarrollaban las órdenes regulares en el último tercio del XVI.

CD30-positive T-cell lymphoproliferation of the bulbar conjuntival mucosa showing spontaneous remission
Authors: Marticorena Álvarez Paula , Garrido Ceca Guadalupe , Guijarro Rojas Mercedes
Published: December 2021

Introduction: CD30-positive T-cell lymphoproliferative lesions represent a spectrum of heterogeneous disorders.

Clinical case: An incision biopsy was performed in a 25-year-old man with a lump in the bulbar conjunctiva. Immunohistochemistry indicated membrane positivity for CD3 and CD30 in over 75%. PCR identified the monoclonal nature of the T-cells. The hematological study was normal. Following biopsy, the conjunctival tumor diminished until disappear.

Conclusions: Mucosal CD30-positive T-cell lymphoproliferation could be ascribed to a reactive process but it is necessary to rule out a primary conjunctival tumor or the first manifestation of an anaplastic large cell lymphoma.

Z zastosowaniem badań diagnostycznych oraz sondażu diagnostycznego przebadano 98 pacjentów biorących udział w programie lekowym.
Infrastructure investment and employment: Evidence for Portugal
Authors: Pereira Alfredo M. , Pereira Rui M. , Rodrigues Pedro G.
Published: December 2021

We estimated how investment in 12 infrastructure types affects employment in Portugal. Using a vector-autoregressive specification at the industry level, we found a double dividend associated with ports and airports: investing in either delivers the greatest bang per euro, both on impact and in the long run. One million euros invested in ports and airports creates 717.1 and 290.5 jobs in the long run, respectively, and 535 and 253.3 jobs in the short run, respectively. Regarding long-term employment effects, these are followed by municipal roads, telecommunications, national roads, health structures, education facilities, refineries, railroads, and highways. Water infrastructures and electricity and gas infrastructures have negligible effects. With the long-term effects decomposed, sizable supply-side employment effects for health and education facilities exist, while demand-side effects dominate for airports, ports, municipal roads, and telecommunications. Employment following the investment in national roads is balanced across demand and supply channels. We found no significant employment-related location effects of infrastructure investments. Also, investing in either health facilities or in education buildings entails non-negligible job losses in the short run. These results suggest that the magnitude and the timing of job creation crucially depend on the type of infrastructure investment. Policymakers in Portugal need to be aware of this in choosing between countercyclical or structural targets.
La alusión como mecanismo cognoscitivo
Authors: Chamizo Domínguez Pedro J.
Published: December 2021

A pesar de que la alusión es ampliamente usada por poetas, escritores y filósofos así como en el lenguaje cotidiano, sus características y alcance como instrumento cognitivo se han estudiado escasamente. Esto es cierto hasta el extremo de que el sustantivo alusión no es merecedor de una humilde entrada en diccionarios y enciclopedias especializados, no solamente de filosofía, sino tampoco de lingüística. Teniendo en cuenta este status quaestionis, este trabajo intenta conseguir los siguientes objetivos, a saber: 1) mostrar que la alusión es un instrumento cognitivo; 2) delimitar la alusión con respecto a la cita, el plagio y el eco; 3) considerar la alusión como un caso de implicatura; y 4) analizar las principales características de la alusión. Todos estos puntos se estudian mediante el recurso a textos poéticos y filosóficos serios, así como a textos y proferencias humorísticos y del lenguaje cotidiano.
La reelaboración de la dictadura del proletariado en Antonio Negri y Slavoj Žižek.
Authors: León Casero Jorge
Published: December 2021

A diferencia de lo ocurrido con la lucha de clases, la mayor parte de las reelaboraciones teóricas (post)marxistas de las últimas décadas han evitado recuperar la dictadura del proletariado, si bien en su origen estaban indisolublemente unidas. Como consecuencia, su significado marxista originario sigue confundiéndose con el significado jurídico-burgués de dictadura como forma de gobierno. Frente a esta situación, el presente artículo expone la reelaboración teórica de la dictadura del proletariado realizada —desde posiciones claramente divergentes— por Slavoj Žižek y Antonio Negri. En el primer caso, Žižek recupera el término explícitamente para oponerlo a la concepción liberal de democracia, por considerarla incapaz de erigirse como alternativa al capitalismo. En el segundo, si bien se elude el empleo explícito del término, se desarrolla una concepción de la democracia y lo común que recupera y adapta el significado marxista originario de la dictadura del proletariado como transición a un común(ismo) sin Estado.
La topología como acceso a la teoría lacaniana
Authors: Sánchez Gómez Pablo Bernardo
Published: December 2021

En este texto se lleva una lectura de la obra lacaniana a través del estudio de sus figuras topológicas. En este sentido, se afirma que el psicoanálisis lacaniano no hace uso de la topología como si no de una herramienta externa si tratase, es decir, como un modo a través del cual obtener ejemplos ilustrativos y explicaciones, sino que el propio pensamiento lacaniano es en sí mismo topológico y, por tanto, no puede ser comprendido al margen de esta dimensión que atraviesa la totalidad de su recorrido. Para ello se estudiarán seis figuras: el grafo del deseo, la cinta de Moebius, el toro, la botella de Klein, la esfera provista de un cross-cap y el nudoborromeo.
Identifying Medieval Fragments in Three Musical Instruments Made by Antonio Stradivari
Authors: Échard Jean-Philippe , Albiero Laura
Published: December 2021

This article identifies ten fragments, used as reinforcements in the sounding boxes of three instruments made by Antonio Stradivari (Cremona, ca. 1648–1737), which are now kept in the Ashmolean Museum in Oxford (the ‘Cipriani Potter’ violin, 1683, and the ‘Hill’ guitar, 1688) and the musée de la Musique in Paris (the ‘Vuillaume’ guitar). The fragments appear to come from a single book of hours, made in Italy no later than the mid-fifteenth century. This identification allows the documentation of the use of parchment fragments in the making process of Stradivari. The authors discuss what the common origin of parchment fragments found in three distinct instruments implies for the authenticity and relative dating of their making. Finally, this study sheds light on the potential of documenting reused parchment fragments, which are widely present in many string musical instruments produced in the sixteenth to eighteenth centuries.
Evaluation of drug release kinetics from polymeric nanoparticles loaded with poorly water-soluble APIs
Authors: Pavaloiu Ramona-Daniela , Sha’at Fawzia , Hlevca Cristina , Sha’at Mousa , Savoiu Gabriela , Osman Sibel
Published: December 2021

The aim of this research was to investigate the release behavior of a combination of two poorly water-soluble active pharmaceutical ingredients (APIs) from poly (D,L-lactide-co-glycolide) (PLGA) nanoparticles. Amlodipine besylate - AML, a calcium channel blocker, and valsartan - VAL, an angiotensin II receptor antagonist drug, were used as poorly water-soluble model drugs. PLGA nanoparticles loaded with AML-VAL (1:16 w/w) were obtained by nanoprecipitation using an amphiphilic block copolymer - Pluronic F127 as stabilizer. The drugs release from the PLGA nanoparticles was determined by a dialysis membrane method under sink conditions. Nanoparticles provided a slow release for both APIs and an attenuated burst effect compared to free drug. Five kinetics models such as Zero-order, First-order, Korsmeyer-Peppas, Higuchi and Hixson-Crowell were applied to predict drug release profiles. The Higuchi and Korsmeyer-Peppas models (R2 > 0.97) best described physicochemical release phenomenon for each PLGA formulations.

This paper aims at creating a new Trust Management System (TMS) for a system of nodes. Various systems already exist which only use a simple function to calculate the trust value of a node. In the age of artificial intelligence the need for learning ability in an Internet of Things (IoT) system arises. Malicious nodes are a recurring issue and there still has not been a fully effective way to detect them beforehand. In IoT systems, a malicious node is detected after a transaction has occurred with the node. To this end, this paper explores how Artificial Intelligence (AI), and specifically Linear Regression (LR), could be utilised to predict a malicious node in order to minimise the damage in the IoT ecosystem. Moreover, the paper compares Linear regression over other AI-based TMS, showing the efficiency and efficacy of the method to predict and identify a malicious node.

Published: December 2021

The Routing Protocol for Low power and lossy networks (RPL) is used as a routing protocol in IoT applications. In an endeavor to bring out an optimized approach for providing Quality of Service (QoS) routing for heavy volume IoT data transmissions this paper proposes a machine learning-based routing algorithm with a multi-agent environment. The overall routing process is divided into two phases: route discovery phase and route maintenance phase. The route discovery or path finding phase is performed using rank calculation and Q-routing. Q-routing is performed with Q-Learning reinforcement machine learning approach, for selecting the next hop node. The proposed routing protocol first creates a Destination Oriented Directed Acyclic Graph (DODAG) using Q-Learning. The second phase is route maintenance. In this paper, we also propose an approach for route maintenance that considerably reduces control overheads as shown by the simulation and has shown less delay in routing convergence.

IP telephony have played an essential role during the COVID 19 pandemic lockdown. One of the issues that lower the service level of the IP telephony solutions is the inefficient bandwidth exploitation. This paper proposes a Smallerize/Zeroize (SmlZr) method to enhance bandwidth exploitation. The SmlZr method is explicitly designed for the P2P IP telephony calls over IPv6 networks. The essence concept of the proposed method is to use the unnecessary fields in the header to keep the voice media of the packet. Doing so leads to smallerize or zeroize the packet payload and, thus, enhance the bandwidth exploitation. The SmlZr method has outperformed the RTP method for all the comparison parameters. For instance, the SmlZr method shrinks the bandwidth by 25% compared to the RTP protocol. Bandwidth saving is helpful for P2P IP telephony calls because it alleviates the traffic load. Thus, improve the call capacity boosts the call clarity.

An eco-friendly method for the synthesis of granular activated carbon was developed in this study. Two types of activated carbon and three types of activated carbon granules have been obtained using different binders, and their properties have been determined. The approach requires adding other binders and waste materials to improve the granulation of activated carbon. Activated carbon was prepared from birch wood chips. Prepared carbon was granulated with a) gas generator tar, b) phenol-formaldehyde resin, and c) polyvinyl acetate to obtain granular activated carbon. This work aims to study the possibilities of using activated carbon adsorbents for CO2 adsorption. The activated carbon produced was characterized by BET, FTIR, and SEM. The adsorption behavior on CO2 was also studied. Granular activated carbons compression strength was enough to study it in an adsorption bed, and an optimal binder was to be phenol-formaldehyde resin and polyvinyl acetate. The obtained results show that activated carbon granules are suitable for CO2 adsorption and can be used, for example, for the removal of CO2 in the biogas upgrading process. As the sustainability problems are increasing, granules from waste materials could be promising materials for further studies.

Mesenchymal stem cells (MSCs) are multipotent stem cells with numerous features potentially useful in various pathologies. It has been shown that MSCs have regenerative potential due to modulation of immune system response, inflammation diminishing, trans differentiation into various types of cells, proangiogenetic and anti fibrotic influence. Besides all of these traits, MSCs posses anti viral capacity and have been further employed in clinical trails since last year. Here, we revised immunomodulatory, biological and antiviral traits of MSCs, but also pathogenesis of Covid-19 and it’s impact on immune system. Conspicuously, there is a growing number of studies examining effect of MSCs in patients suffering from Covid-19 pneumonia and ARDS. Since MSCs are in theory capable of healing lung injury and inflammation, here we discuss hypothesis, pros and cons of MSCs treatment in Covid-19 patients. Finally, we debate if MSCs based therapy can be promising tool for Covid-19 lung pathologies.

Measurement of Pollution Level with Particulate Matter in Babylon Concrete Plant and Evaluation of Oxidative Stress and Hematological Profile of Plant Workers
Authors: Al–Dulaimi Shaimaa H. , Rabee Adel M.
Published: December 2021

The impact of exposure to different sizes of particulate matter (PM1, PM2.5, PM7, and PM10) was evaluated in  Babylon concrete plant workers who had been exposed to concrete dust for at least 10 years.  The effects of  these particles on the hematological parameters, malondialdehyde (MDA) levels, and  antioxidant enzymes (catalase and glutathione peroxidase ) were examined. The results exhibited that the levels of PM2.5 and PM10 were higher than the acceptable limits approved by the National Ambient Air Quality Standards (NAAQS). The blood parameters, namely white blood cells (WBC), red blood cell (RBC) and platelets counts, demonstrated non-significant differences between workers exposed to the PM as compared to the control group. However, differentiated white blood cells count revealed a signiﬁcant increase of  polymorphonuclear leukocytes (PMN)  in exposed workers in comparison with the control group. However, both  MDA and glutathione peroxidase showed a highly significant increase in the workers ass compared to the control group. Thus, we may conclude that the concrete plant workers are exposed to a higher risk of oxidative stress that could lead to alterations in hematological parameters, enzymatic activities, and MDA level.
School Mathematics and miyō-pimōhtēwin

Published: December 2021

We want mathematics to be a process of miyō-pimōhtēwin (walking in a good way). Using a narrative inquiry methodology, we share our experiences working alongside two Cree elementary school teachers and the students in their mathematics classroom. The teachers taught principles that balance kohtawān (our spiritual being) and make curriculum into a relational space. The principles invite school mathematics to be learned and taught in a way that foregrounds self-awareness, doing things properly, learning new ways, being thankful, being humble, leaving problems behind you, helping yourself and keeping trying. This paper also demonstrates a promising practice of Indigenization in the mathematics classroom by providing a contextual way in which Cree students and teachers engaged in school mathematics in relational ways.

Розглянуто особливості будови та основні проблеми отримання перспективного виду композиційних будівельних матеріалів – дисперсійно-армованих бетонів (фібробетонів), що складаються з будівельної матриці та армуючих волокон. Проаналізовано результати відомих на даний час досліджень по застосуванню плазми тліючого розряду для обробки поверхонь армуючих волокон з неорганічних та полімерних матеріалів з метою підвищення їх адгезії до матричного матеріалу. Аналіз джерел свідчить, що модифікація поверхонь волокон тліючим розрядом суттєво підвищує міцність зчеплення волокон із будівельним матеріалом і є перспективним технологічним напрямком. Визначено, що обмеженість застосованих способів і режимів плазмової обробки волокон робить доцільним подальше проведення досліджень. Представлена в статті інформація має оглядовий характер.
Evaluation of Nursing Students’ Perspectives toward Objective Structured Clinical Examination
Authors: A. Bdair Izzeddin
Published: December 2021

Nurses need to master the core nursing competencies to perform their professional duties effectively. The Objective Structured Clinical Examinations (OSCEs) have been integrated as an innovative method of evaluating clinical skills in the nursing curriculum over the years. The study that directed this article aimed to assess nursing students’ perception toward OSCEs. A cross-sectional descriptive design was used. A convenient sample of 429 undergraduate nursing students was enrolled. In addition to demographic data, the OSCEs’ evaluation questionnaire was used to gather data. The questionnaire assessed nursing students’ evaluation of the OSCEs’ attributes, the quality of OSCEs’ performance, and OSCEs’ scoring and objectivity. Seven questions about the evaluation of the OSCEs’ organisation were added. About two-thirds of the students were female (69.2%) and belonged to the age category of younger than 24 years (59.9%). The OSCEs were rated the most preferred assessment method for clinical competencies and fit for all student levels. Nursing students showed positive perspectives toward OSCEs’ attributes, quality of performance, scoring and objectivity, and organisation. OSCEs have been used as an innovative method of evaluating clinical nursing skills. OSCEs are accepted well by nursing students. The study recommends that academic institutions have to design OCSEs well in terms of preparation, planning, equipping labs, organisation, implementation, follow-up, and monitoring, and they should consider faculty and students’ feedback to make it more effective and valuable.
