Bulky PNP Ligands Blocking Metal-Ligand Cooperation Allow for Isolation of Ru(0), and Lead to Catalytically Active Ru Complexes in Acceptorless Alcohol Dehydrogenation
Authors: Deolka Shubham , Fayzullin Robert R. , Khaskin Eugene
Published: May 2021

We synthesized two 4Me-PNP ligands which block metal-ligand cooperation (MLC) with the Ru center and compared their Ru complex chemistry to their two traditional analogues used in acceptorless alcohol dehydrogenation catalysis. The corresponding 4Me-PNP complexes, which do not undergo dearomatization upon addition of base, allowed us to obtain rare, albeit unstable, 16 electron mono CO Ru(0) complexes. Reactivity with CO and H2 allows for stabilization and extensive characterization of bis CO Ru(0) 18 electron and Ru(II) cis and trans dihydride species that were also shown to be capable of C(sp2)-H activation. Reactivity and catalysis are contrasted to non-methylated Ru(II) species, showing that an MLC pathway is not necessary, with dramatic differences in outcomes during catalysis between iPr and tBu PNP complexes within each of the 4Me and non-methylated backbone PNP series being observed. Unusual intermediates are characterized in one of the new and one of the traditional complexes, and a common catalysis deactivation pathway was identified.

Published: May 2021

Introduction. Increasing the efficiency of using a warehouse with a constant volume is an urgent task, the solution of which is possible through block or deep-lane storage systems. One such solution is the pallet flow rack, which saves up to 25% of the distance travelled by a forklift compared to the single-deep racks. The main element of the safe operation of the gravity roller conveyors used in a pallet flow rack is a brake roller. The most promising design is a magnetic (eddy current) type brake roller.

The purpose of the work is to carry out a comparative analysis of the results of the calculated and experimental studies to determine the speed of movement of a pallet along a magnetic brake roller.

Materials and methods. The research area is the magnetic brake roller. Its construction and description of work presented. The results of calculated and experimental study of the coefficient of magnetic viscosity presented.

Results. The calculated and experimental dependences of the pallet movement speed along the magnetic brake roller were obtained. It was found that with an increase in the speed of movement of the pallet along the magnetic brake roller, the error of the mathematical model increases, and, first of all, after crossing with the straight line of a drag peak speed.

Conclusions. A comparative analysis of the results of the calculated and experimental studies to determine the speed of movement of the pallet along the magnetic brake roller carried out. It was found that the developed design of a magnetic brake roller in the operating range of the pallet masses from 100 to 600 kg with up to 16 magnets located on one side of the disc, and from 100 to 1150 kg with up to 8 pairs of the magnets located on both sides of the disc, provides a speed control within the limits not exceeding the permissible speeds of the pallet movement on the gravitational roller conveyor. The verification of the mathematical model showed that the average value of the error of the mathematical model in the entire range of the pallet masses at speeds not exceeding the permissible speeds of pallet movement on a gravitational roller conveyor and below the drag peak speed is no more than 8.2%.
Сomparative analysis of efficiency of use a screw drill on frozen soil
Authors: Martiuchenko I. G. , Zenin M. I.
Published: May 2021

Introduction. Drilling of frozen and permafrost soils is one of the complex and energy-intensive processes of earthworks. Drilling tools used on frozen soils implement the process of drilling the soil by deformation of cutting or crushing action. Current drilling tools are not efficient enough to use because they implement energy-intensive drilling processes and are not always suitable for various types of soils. A screw drill is considered, which implements the process of soil destruction by shear and shear deformation, which is less energy intensive.

Materials and methods. On the basis of theoretical studies of the interaction of 3 types of drilling tools with frozen soil, a comparative analysis was carried out to determine the efficiency of a screw drill use. The technical and economic indicators of the drilling process were compared. A method for determining the efficiency of the use a screw drill based on the analysis of special target functions is presented.

Results. The results of a comparative analysis of drilling tools have been obtained. Depending on the nature of soil deformation, the effectiveness of one drilling tool over another is determined. As a result of a comparative analysis of the drilling speed and the energy intensity of the drilling process, the efficiency of the screw drill was established.

Discussions and conclusion. In the course of the comparative analysis, the efficiency of the screw drill was determied, which implements shear deformation and soil separation, justifying the feasibility of further research.

Published: May 2021

Introduction.The problem of the shortage of energy-efficient restoration technologies makes it a priority to develop new technological equipment for the restoration of the rolling surfaces of railway wheels using highly concentrated energy sources. Currently, in the practice of repair DPO, discarded non-bonded wheels are increasingly replaced with new ones, but their resource potential is high during the operation. This approach is not technically and economically feasible.

Materials and methods.This article presents the results of the strength calculation of the main moments of forces and dynamic loads per wheel pair. The problem of repair equipment related to the lack of the independent mobile complexes that ensure prompt arrival at the work site and high quality restoration of the design geometry of the wheel surface is formulated.

Results.To solve this problem, a mobile complex was designed and developed, which allows to restore the design geometry and modify the high physical and mechanical properties of the riding surface with optimal stresses in the phase structure of the wheel base.

Discussion and conclusion.It is recommended to use the results of the research carried out for the design, creation and production of high-tech repair equipment.
Use of fibre waste as a binder
Authors: Chulkova I. L. , Selivanov I. A.
Published: May 2021

Introduction.The need for a more efficient and varied use of waste from the pulp and paper industry dictates the need to search for new directions for the use of such waste in construction materials science technologies.

Materials and methods.In the studies the fibre waste of the Perm Cardboard LLC company with a moisture content after washing of 300% by weight was used. Currently, many issues of theory and practice the production of materials from the fibre waste are not entirely solved, resulting in a number of provisions borrowed from the theory of the production of concrete mineral aggregates, as well as the production of pulp and paper industry.

Results.Due to its chemical and material composition, the possibility of using the fibre waste in construction materials science technologies as an independent air binder is shown. The studies have established that the initial moisture content of the fibre waste as a binder affects the final quality indicators of a dry material. Thus, the lowest dry material density of 350 kg/m3 is observed at the initial humidity of the mixture in the range of 650% by weight. At a density of 350 kg/m3, the hygroscopicity of the material is 4.3%, the shrinkage from 10 to 25%. The drying time of the product is within 11 hours. A leveling high shrinkage is achieved by introducing light aggregates with a rough surface during the molding process.

Discussion and conclusions.The obtained data on the structure, the composition of the fibre waste, as well as the dependence and regularities of the behavior of a highly concentrated dispersed system of the ‘fibre waste-water’ type show the possibility of using the fibre waste for the production of thermal insulation materials, both as a main component and in a composition with aggregates as an independent air binder. At the same time, the final density indicators of thermal insulation products are within the limits established by regulatory documents.
Model of shear test for tearing strength of concrete
Authors: Krasnoshchekov Yu. V.
Published: May 2021

Introduction. To control the concrete strength of reinforce concrete structures the shear test based on the empirical proportional dependence of concrete strength and tear force of a special purpose anchor with an expanding cone is used. The absence of a physical model of a concrete deterioration when tearing strength is a sign of the defect of the method which hampers the search of the ways for accuracy increase and test validity. The purpose of this study is to develop a physical model of concrete deterioration to determine the calculated strength by the shear test.

Materials and methods. The concrete strength model is a mechanism for local deterioration by tearing out a body of concrete in the form of an indicative cone when extracting it from a pre-fabricated anchor well. It is accepted that the deterioration occurs in two stages: from the melting of the concrete to the formation of cracks in the plane of the apex of the concrete cone in the first stage and the subsequent formation of cracks along the lateral surface of the cone during the extraction of the anchor. For transition to compression resistance, the average of the ratio of concrete resistance to compression and tensile or Fere formula shall be used. The model was verified by the calculation of 6 test measurements.

Conclusions. It has been established that the empirical correlation between the resistance of concrete to compression and the force of extraction of the anchor in the concrete test is only possible if the resistance of concrete is linearly related to compression and extension. However, the actual ratio of concrete resistance to compression and tensile is non-linear, so for relatively weak concrete the possibility of overestimating the strength of concrete on compression empirical dependence is offset by a reduction factor, and for more durable concrete, measurements are underestimated.

La Constitución de 1918: miradas desde la filosofía, la academia y la política
Authors: Collazo Marcia
Published: May 2021

La Constitución uruguaya de 1918 supone un verdadero pacto refundacional para el país. En ella confluyen tres grandes enfoques: el de la filosofía política, representado por los Apuntes de José Batlle y Ordóñez; el de cuño político partidario, emanado de las actas de la Convención Nacional Constituyente, y el académico, producido en el marco de nuestra incipiente ciencia jurídica y representado por varias publicaciones, entre las que se destaca la obra de Martín C. Martínez (1918). Este trabajo pretende realizar un análisis desde la mirada de la filosofía del derecho en torno a dichas contribuciones, centrándose especialmente en los aportes teóricos y metodológicos de la academia, a fin de investigar qué presupuestos teóricos, filosóficos, humanos, sociales, culturales y políticos influyeron en la creación de dicha Carta Magna.

Análisis histórico del acceso a nuestra justicia civil
Authors: Moreno Diego
Published: May 2021

El acceso a la justicia es un derecho humano fundamental que comprende una dimensión ética esencial en la realización de la dignidad de las personas. Se ubica vinculado a dos principios y derechos esenciales como la igualdad ante la ley y por consiguiente la no discriminación. Es un derecho humano y a su vez protector del resto de los derechos en general. ¿De qué sirve tener derechos si no existe forma de acceder a las instituciones que permitan el pleno goce y ejercicio de estos? La imposibilidad de acceder a la justicia frustra el ejercicio real de la ciudadanía y atenta contra el Estado Democrático de Derecho. Se torna una garantía fundamental y obtiene reconocimiento normativo a nivel nacional, regional e internacional. Existen diversas circunstancias de carácter social, económico y cultural  que  favorecen un verdadero acceso a la justicia o por el contrario limita, entorpece o directamente elimina el camino hacia esta. Como todo derecho es fruto de una evolución y el presente artículo pretende realizar un análisis histórico que permita comprender sus raíces  en nuestro ordenamiento jurídico, de manera tal, de vislumbrar a cabalidad su consolidación actual y a su vez proyectarnos hacia el futuro.

Los derechos humanos en la complejidad latinoamericana: una cuestión de «democracia radical»
Authors: Garcé Luis Meliante
Published: May 2021

Este trabajo aborda desde una mirada «crítica» y en clave latinoamericana, un aspecto relevante de las sociedades complejas contemporáneas del continente, como es el tema realmente polifacético de los llamados derechos humanos, con una breve referencia particularizada a Uruguay avanzado ya el siglo XXI. En ese contexto general, se analiza la viabilidad de proponer un concepto de «humanismo» y en su inherencia, los de «sujeto» y «subjetividad», que sean propios para el mismo. En el planteo que se realiza, se prioriza el contenido político del tema, lo que desemboca finalmente en el resultado que se postula y que se concreta vinculándolo con el concepto de «democracia radical».
La circulación de la prensa obrera en el Cono Sur: un abordaje metodológico para el análisis de fuentes documentales
Authors: Gastelumendi Cecilia Demarco
Published: May 2021

Este trabajo pretende formular algunas de las cuestiones metodológicas- ancladas en la reflexión teórica- que deberemos enfrentar para abordar los objetivos de un proyecto de investigación de más largo alcance. Se pretende en esta instancia  definir problemas, categorías de estudio y metodologías, que nos llevarán a puntualizar hacia dónde dirigir la mirada en la lectura la prensa obrera en tanto fuente historiográfica para reconstruir a la vez la circulación de los ejemplares como la circulación de ideas políticas de las que éstos son soportes. Evaluaremos de esta forma sus posibilidades y limitaciones en tal sentido. Para estudiarla desarmamos analíticamente el proceso en los cuatro momentos establecidos por el historiador H. Tarcus (2007, 14): producción, distribución, recepción y apropiación, entendidas como instancias progresivas que se alimentan unas a otras y que se encuentran en todas las instancias. La prensa se encontró en un nudo, en un cruce de caminos de estos cuatro momentos.
La normatividad como objeto: doctrina, teoría, metateoría
Authors: Aguirre Ricardo Marquisio
Published: May 2021

El propósito de este artículo es distinguir entre tres modos de abordar la normatividad jurídica en las disciplinas que toman al derecho como objeto de estudio. Las variantes de la normatividad que voy a considerar son la formal, la conceptual y la funcional. La primera aparece ligada a la doctrina. La segunda es la tematizada por la teoría general del derecho a partir del desarrollo del positivismo jurídico como proyecto conceptual y descriptivo. La tercera variante ha llevado a la constitución reciente de un campo de la filosofía práctica, la metanormatividad, originado en la metaética, conectando a todas las disciplinas que se enfrentan al problema de la caracterización normativa de la agencia práctica (moral, ética, derecho). El reconocimiento de estas distinciones es útil para despejar algunos equívocos que suelen plantearse en la teoría y práctica jurídica acerca de cuestiones tales como las consecuencias de la inclusión de términos morales en las normas jurídicas, el sentido del lenguaje de los derechos y la relevancia argumentativa de la Constitución, entre otros.

COMPARATIVE ASSESSMENT OF THE QUALITY OF THE RESULTS OF ORTHODONTIC TREATMENT IN CLINICS OF DIFFERENT FORMS OF OWNERSHIP IN ST. PETERSBURG
Authors: E.S. Vinogradova
Published: May 2021

In the modern literature, various methods of qualitative and quantitative assessment of dentofacial anomalies are described. They are reduced to determining the localization of disorders, describing the causes of their occurrence, considering the functional state of the dentofacial system, as well as to quantifying the degree of violations of facial aesthetics, occlusion, morphology and function in various dentofacial anomalies. The method developed by us for assessing the quality of the results of orthodontic treatment allows us to conduct an expert assessment of the quality of the orthodontic treatment performed on the basis of tables developed and structured according to several blocks. Assessment of the quality of orthodontic treatment consists of three blocks: assessment of the quality of the results of orthodontic treatment, assessment of the process of orthodontic treatment, assessment of the maintenance of medical records. The task of the proposed method for assessing the quality of orthodontic treatment is to improve the quality of diagnosis of dental-facial anomalies and the quality of the results of orthodontic treatment. This paper presents the results of assessing the quality of the clinical component of orthodontic treatment in clinics of various forms of ownership in St. Petersburg. The clinical evaluation of the results of orthodontic treatment consists of an assessment of: the aesthetics of the face, the aesthetics of the smile, the occlusal ratios of the dentition, the articulation ratios of the dentition, the temporomandibular joint, the position of individual teeth and dentition, the integrity of the dentition, the integrity of the teeth, the condition of the periodontium and the timing of orthodontic treatment. The study was conducted in state-funded health care institutions and in private, including network, clinics. According to the results of the study, it can be concluded that the data on assessing the quality of clinical results of orthodontic treatment in clinics of different ownership forms do not have significant differences.

Authors: L.G. Pinchuk , E.M. Maltseva , I.N. Egorova
Published: May 2021

The licorice genus (Glycyrrhiza L.) plants are widely used in conventional and traditional medicine in different countries around the world. The genus includes about 15 species, but only three of them - G. glabra, G. uralensis and G. inflata are well studied and included in the Europe and Asia pharmacopoeias. Pale-flowered licorice (Glycyrrhiza pallidiflora Maxim.) is a perennial herbaceous plant from the false (not sweet) licorice section (Pseudoglycyrrhiza Krug.), which do not accumulate glycyrrhizin derivatives. This East Asian species grows in the Russian Far East. The distribution area of G. pallidiflora is limited. Only a few of its geographically isolated habitats are known: within the Khabarovsk city, near the Sarapulskoe village (Lower Amur) and in the Primorsky Kray on the Ryabokon Peninsula on the Lake Hanka southeastern coast. The G. pallidiflora successful introduction on the Kemerovo region-Kuzbass territory has been carried out over the past 5 years in the “Apothecary garden” territory of the Kuzbass Botanical Garden of the Institute of Human Ecology, FRC UUH SB RAS, Kemerovo. Currently, the scientific literature contains limited information on the composition and quantitative content of biologically active compounds (BAC) in the aerial part of G. pallidiflora. Therefore, the main task is to conduct phytochemical studies of the main classes of BAC, which have a pronounced pharmacological activity. We have proposed the amount of flavonoids quantitative determination method in the pale-flowered licorice herb, introduced in Kuzbass, by the differential spectrophotometry method, based on aluminum (III) chloride complexation reaction. The flavonoids extraction conditions from raw materials have been studied. They depend on the ethyl alcohol concentration, the plant raw materials grinding degree, the extraction time, and the raw materials and extractants ratio. The optimal extraction conditions were selected and a quantitative determination method was developed. On the base of it was established that the amount of flavonoids content in the herb of pale-flowered licorice (Glycyrrhiza pallidiflora Maxim.), in terms of rutin, is from 2.25 ± 0.38% to 2.44 ± 0, 04%. The relative error of the proposed method is ± 3.21%.

Pale-flowered licorice (Glycyrrhiza pallidiflora Maxim.) is the pea family (Fabaceae) perennial herb. It is a Russian Far East endemic. Pale-flowered licorice refers to the false (not sweet) licorice section (Pseudoglycyrrhiza Krug.), which do not accumulate glycyrrhizin derivatives. The G. pallidiflora successful introduction has been carried out over the past 5 years in the “Apothecary garden” territory, FRC UUH SB RAS, Kemerovo. Phytochemical studies screening biologically active compounds main classes of the plant aerial part confirmed the presence of a complex of phenolic compounds. The content of catechin derivatives and condensed-type tannins - proanthocyanidins (PAC) data in G. pallidiflora herb were obtained for the first time. In different years of cultivation, licorice herb accumulates phenolic compounds - up to 2.83 ± 0.22% in terms of gallic acid, flavonoids - up to 2.44 ± 0.03% in terms of rutin and PAC in terms of cyanidine chloride - up to 2.61 ± 0.11%. It was found that the maximum content of the phenolic compounds and PAC sum was observed in the herb for 4 years development. The greatest number of flavonoids accumulates in the herb harvested in the 3rd year of cultivation. A positive significant linear relation was found between antioxidant activity (AOA) and the total phenolic compounds and PAC content (r≥0.98). Considering that BAC with IC values ≤ 50 μg / ml in the DPPH assay refer to active antioxidant’s licorice herb can be classified as a plant with high antioxidant potential.
It was found that the iron chelating activity of the G. pallidiflora herb is in direct dependence (r≥0.94) on the content of flavonoids. The obtained results demonstrate the importance of further study of this plant as a source of BAC, including plant antioxidants.

The subject of our study is the positionality of children in the process of urban revitalization. We understand the city as a learning space. From our point of view changes introduced into that space are always interventions into children’s learning processes. In the article we present an empirically based reconstruction of practices of community cultural animations that aim at empowering children’s voice in the processes of revitalization. Konrad Dworakowski’s and Pinokio Theatre’s community cultural animations, realised from 2014 to 2019 in Łódź, offer interesting examples of such practices. Even though we build or argument on the basis of observations collected in Łódź, it can be reliably reflected in discussions on educational issues in urban changes in other post-industrial cities.

Published: May 2021

Two new ternary copper(II) complexes [Cu(2-phenoxyacetate)2(temed)] (1) and [Cu(4-chlorobenzoate)2(temed)] (2) are synthesized by the addition of temed (N,N,N',N'-tetramethylethylenediamine) to Cu(II) 2-phenoxyacetate/4-chlorobenzoate in a water:methanol (1:4, V/V) mixture. The newly synthesized complexes are characterized by elemental analyses, spectroscopic techniques (UV-Vis, FTIR), magnetic moment, molar conductance and single crystal X-ray diffraction. In both crystals, the asymmetric unit consists of one half of the neutral complex in which the central metal atom lies on a glide plane in 1 and on a twofold axis in 2. Both ternary complexes are neutral and consist of six coordinated CuN2O4 chromophores. In both complexes, the Cu(II) metal centre is coordinated by two nitrogen atoms of chelating temed and four oxygen atoms from two bidentate 2-phenoxyacetate/4-chlorobenzoate ligands. Detailed packing analyses of complexes 1 and 2 reveal that the C—H…p interaction along with weak intermolecular C—H…O hydrogen bonding interactions provide the stability and robustness of the crystal lattice.

Background Prostate cancer is a common malignancy in men; however, sarcoma of the prostate is an uncommon variant. Sarcoma of the prostate occurs in all age groups with rhabdomyosarcoma being more common in children while leiomyosarcoma occurs more in the older adults. Stromal tumour of uncertain malignant potential (STUMP) occurs in adults. Modalities of treatment include surgery, radiotherapy and chemotherapy used singly or in combination, but all report poor long term survival despite treatment selected. We present 2 cases of prostate stromal tumours. Case report We present two patients in their fourth decade who presented with acute urinary retention. Computed tomography scan was performed in both cases and showed a large tumour arising from the prostate. Prostate specific antigen was less than 4ng/ml in the two cases and core needle biopsy performed and samples taken for histology. The histology reports showed embryonal carcinoma and STUMP in the first and second cases respectively. Conclusion Prostate sarcomas are uncommon but may pursue aggressive clinical course while STUMP has a variable course. Early diagnosis and use of combined modalities of treatment may be required to improve survival.

En ello se infiere un acicate para la transformación de las formas organizativas y de construcción en los centros educativos. Bajo este panorama, la integración de las TIC educativas se han integrado en las escuelas y han ido generando lazos de dependencia y colaboración entre los agentes educativos. En estos centros educativos se han desarrollado unas dinámicas que apuntan al reforzamiento de la idea de que las TIC han favorecido la aparición de indicios de que se está construyendo una comunidad de aprendizaje. Cuando se habla de la implementación digital, se habla del uso crítico de las TIC en el que se considera que éstas se utilizan como herramientas cognitivas, es decir, articuladas a un fuerte componente pedagógico y psicológico capaz de contribuir al desarrollo de habilidades de orden superior como razonar, inferir, interpretar, argumentar, proponer, modelar, tomar decisiones, resolver problemas, entre otros. Así mismo, al hacer notable la complejidad social que estos aspectos pedagógicos estimulan en los agentes implicados, la planeación estratégica surge a manera de proposición para hacer frente a la gestión eficaz de esta integración digital y construcción social de las Comunidades de Aprendizaje que satisfagan las necesidades de calidad educativa en materia de equidad, interculturalidad y competitividad global.

Replantear el sentido de la condición humana desde el fenómeno pandémico ¿cambio o mutación? una reflexión desde la perspectiva de los procesos educativos universitarios
Authors: García Ramírez Juan , Ruiz Balza Alejandro
Published: May 2021

Repensarnos desde lo digital, ciudadanos digitales, aislados pero unidos por la ciber comunicación; ¿estará en riesgo lo humano? o mutaremos a una nueva manera de humanizar nuestra relación con el entorno y la naturaleza afectando lo menos posible nuestra condición humana. Este punto es crucial porque hay personas que hemos vivido entre siglos. Partimos de una micro mirada vertical y manual para introducirnos a la mirada horizontal y digital. No es posible extraviar las características que nos definen como seres humanos: libertad, voluntad, trascendencia, conocimiento, pensamiento, abstracción, entre otros. Lo que sí está en riesgo es la sensibilidad y conciencia para ajustar la digitalización al servicio de la humanidad. Parece que hacemos lo contrario y queremos ajustar la condición humana a la era digital. Ahora una pantalla con miles de pixeles reproduce imagen y sonido. Es la ciber comunicación tan efectiva en algunas cosas y tan fría en otras. El confinamiento, consecuencia estratégica para evitar la mayor parte de contagios trae consigo cambios disruptivos que afectan de diversas maneras el sentir y vivir humano.
The Musings of ‘Evil Bastards’: Perspectives from Social Casino Game Professionals
Authors: Reynolds Jennifer
Published: May 2021

Technology has blurred the lines between gambling and gaming. While the convergence can be witnessed on many different levels, social casino games on social networking sites and mobile apps illustrate just one example. Much of what we currently know about social casino games focuses on player behaviour, with little understanding about this genre from the perspective of social game professionals. This paper aims to fill the gap in our understanding of social casino games through interviews with the professionals who design them.
In-depth interviews were conducted with 14 professionals from the social casino games industry. Interviews were analyzed using thematic analysis. Findings illustrate tensions that exist between the two fields of gambling and gaming; however, both are trying to separate themselves from the stigmatized ‘dirty secret’ that is gambling. Further, as a result of social casino games residing, for the most part, in an unregulated ‘grey area,’ findings illustrate the ethical struggle felt by social casino game professionals. This convergence has significant consequences, not only for players, but for game developers, designers, and researchers, and highlights the importance of game designer education.
Exhaled breath condensate: a potential tool to evaluate the relationship between inflammation and dyspnea in patients with chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) is a respiratory disease with high prevalence. Many factors contribute to its development, and probably that leads to its various clinical pictures. Inflammation is the mechanism responsible for the structural alterations in the lungs. Despite its heterogeneity, there are a couple of primary symptoms characterizing it, which are chronic and productive cough and dyspnea. The understanding of dyspnea in COPD is based on theories deriving from the interaction of a network formed between the cardiorespiratory and the neuromuscular system and their receptors. Many factors contribute to its occurrence, making it complex and giving it a very subjective character for a person to perceive. Various methods are used to study COPD. Non-invasive ones seem to attract attention nowadays. One of them is the exhaled breath condensate. It is a biofluid with rich content, which can capture a picture of the pathological processes happening in the lungs. Its study has shown that some markers of inflammation and oxidative stress, such as 8-isoprostane and H2O2, are elevated and able to connect dyspnea and inflammation. Additionally, they seem to provide information of the ongoing inflammatory process in the lungs as well as a picture of the severity of the symptoms. This evidence may enhance the association of dyspnea with dysfunctional breathing. Despite these interesting findings, further research is necessary both in dyspnea and inflammation in COPD to clarify their mechanisms and connective pathways. The utility of non-invasive techniques such as the exhaled breath condensate could be of significant help, but its establishment in the medical field requires extra studies.

Los estudios históricos sobre la educación de los italianos en la Argentina. Temas, abordajes y algunas propuestas
Authors: Serrao Paula
Published: May 2021

El artículo analiza la producción historiográfica dedicada al estudio de los diversos proyectos educativos que entre fines del siglo XIX y mediados del XX se dirigieron a los italianos emigrados a la Argentina y a sus descendientes. La primera parte se detiene en las investigaciones sobre las escuelas de las asociaciones italianas de ayuda mutua y sobre las escuelas salesianas, analizándolas a la luz de los debates sobre el modelo interpretativo del “crisol de razas” y del “pluralismo cultural”. La segunda parte reflexiona sobre los trabajos que abordan la relación entre los inmigrantes y el sistema escolar argentino, ya sea estudiando las políticas educativas “nacionalizadoras” o la presencia extranjera en la escuela pública. Finalmente, se señalan nuevas fuentes y líneas de trabajo que podrían ampliar las investigaciones del área, como el estudio específicamente educativo del funcionamiento de estas instituciones luego de la Gran Guerra.

Sagrada Família ou Política?

Em suas várias formas, condicionadas pelas culturas e tempos diversos, as famílias eram e são, antes de tudo, realidades sociais terrestres. Fenômeno recente na história humana e de extensão reduzida entre os povos, a Igreja católica nem de longe alcança a vida familiar pelo mundo inteiro. Continuando a tradição judaica e assumindo elementos culturais helenísticos, romanos e germânicos, ela sempre procurou iluminar os núcleos familiares com o sublime mistério de Cristo, desde os códigos familiares das cartas apostólicas até às exortações papais e episcopais da atualidade...
