Fundamentos ontológicos del sistema educativo finlandés como referente para superar problemáticas en contextos emergentes
Authors: Moreno Guaicha Jefferson Alexander , Aguilar Gordón Floralba del Rocío
Published: July 2019

The present work arises from the reflection on the failure of external educational models applied in emerging contexts without considering the reality of each town. According to Carnoy (1974) in the underdeveloped countries there is a strong tradition in copying the cultural forms and models of first world societies, without analyzing the objective and subjective conditions that will determine success or failure. The objective of this document is to analyze the ontological foundations present in the finnish educational system in order to identify the main references that will serve as a basis to overcome problems of the educational reality in emerging societies. The document presents an exploratory, descriptive and comparative review that by nature of the study is of a bibliographic and qualitative nature supported by the use of logical-scientific methods (deductive-inductive) with their respective procedures, and strengthened by the application of philosophical-hermeneutic philosophical methods. The tendency to imitate and to copy educational models alien to our reality has resulted in poor educational systems that do not respond to the specific needs of the educational reality of emerging societies. It is necessary to determine the being, meaning and meaning of the finnish education system with a view to locating essential aspects that could become guidelines for rethinking other educational models.
El concepto de pensamiento crítico según estudiantes chilenos de pedagogía
Authors: Díaz-Larenas Claudio Heraldo , Ossa-Cornejo Carlos Javier , Palma-Luengo Maritza Roxana , Lagos-San Martín Nelly Gromiria , Boudon Araneda Javiera Ignacia
Published: July 2019

This paper analyzes the concept of critical thinking according to the perspective of a group of preservice teachers from a Chilean university; they are currently in the fourth year of their program. Twenty future teachers participated in a focus group discussion in which they expressed their perspectives on the subject. The answers collected were analyzed using the content analysis technique, which allowed the creation of different categories. Among the most recurrent concepts about critical thinking, we could find: analyzing, reflecting, reasoning, change generation and problem solving. The students defined a critical thinker in their different dimensions: as someone competent, both cognitively and socially, and, at the same time, as someone who takes personal and collective aspects into account. The interviewees also mentioned their role of educating critical thinkers, and explained some of the key elements for making that possible. Some of them were: teaching the importance of feeding on reliable information sources, and accepting feedback from their peers. After a comparison between the interviewees’ conceptualizations and the existing literature, it is found that the students’ perspectives are closely related to those of theory.
Compromiso existencial con la enseñanza
Authors: Flores Graciela , Porta Luis
Published: July 2019

The ‘existential commitment with teaching’ is one of the major findings stemming from a hermeneutic study at Mar del Plata State University, Argentina. With the intention of delving into the ethic dimension of university teaching, the narratives and practices of a Philosophy professor were analyzed. This teacher had been singled out by her students as an example of good teaching and had thus come to be regarded as a memorable professor in the context of academic production of the Research Team on Education and Cultural Studies (GIEEC). Existential commitment is indeed present in this professor’s practices and narratives and embedded in a ‘model of recognition’, whose ethic component manifests in the regard of the student as an anthropological pair, the exercise of hospitality and the presence of generosity and empathy in the pedagogical bond. This study discusses materials produced in the methodological articulation of biographic narrative research and ethnographic research in education.

Tecnología con fines lexicográficos: Su aplicación en los Diccionarios Valladolid-UVa
Authors: Fuertes-Olivera Pedro A. , Niño Amo Marta , Sastre Ruano Ángeles
Published: July 2019

Los Diccionarios Valladolid-UVa son un portal lexicográfico integrado que se está construyendo en la Universidad de Valladolid gracias a un acuerdo de colaboración y financiación entre la empresa danesa Ordbogen A/S y el Centro Internacional de Lexicografía de esta universidad. El proyecto se basa en el marco teórico de la Teoría Funcional de la Lexicografía y parte del supuesto de que los datos lexicográficos tienen valor económico en la era de internet. Para lograr maximizar el potencial económico de los mismos es necesario poner en valor lo siguiente: (a) la defensa del diccionario como herramienta de información; (b) un análisis económico del coste-beneficio de la actividad lexicográfica; (c) el empleo de una metodología de trabajo que haga posible un tratamiento de los datos que garantice la calidad de los mismos y su empleo para solucionar las necesidades de información puntual del usuario potencial de los datos; y (d) que la utilización de tecnologías que permitan poner en práctica el concepto de diccionario previamente diseñado mejoren la productividad lexicográfica, es decir la capacidad del lexicógrafo de preparar cada entrada lexicográfica de forma segura, fácil, y rápida. En este trabajo se analizan algunas de las tecnologías desarrolladas en el marco de este proyecto y aplicadas al diseño y construcción de los DiccionariosValladolid-UVa.
El grupo rítmico y el grupo fónico en la clase de ELE
Authors: Planas Morales Sílvia
Published: July 2019

En este artículo se expone la aplicación de la jerarquía fónica (Cantero, 2002) en la didáctica de la pronunciación, argumentando a favor del grupo rítmico y del grupo fónico como agrupaciones de palabras en torno a un acento —paradigmático y sintagmático, respectivamente— que facilitan la adquisición del ritmo del español, con lo cual el alumno de ELE adquiere mayor fluidez en el discurso oral y mejor comprensión auditiva.
La dimensión intercultural de las actividades de los manuales de español de los negocios del nivel B2-C1 del MCER
Authors: Agdanli Aslihan
Published: July 2019

El propósito del presente trabajo es dar a conocer los resultados de una investigación llevada a cabo para analizar cómo el planteamiento metodológico de las actividades de cultura de los manuales contribuyen al desarrollo de la competencia intercultural del alumno. Para ello, se han analizado siete métodos de enseñanza-aprendizaje de español de los negocios del nivel B2-C1 del MCER, publicados en España entre los años 2003 y 2010 prestando especial atención a aspectos como el procedimiento discente mediante el que se aborda el conocimiento en las actividades, las estrategias interculturales promovidas o los intercambios interculturales planteados. El análisis de los manuales me permite concluir que el planteamiento metodológico de las actividades, en general, no es adecuado para activar las habilidades y actitudes interculturales del alumno que le permitan llegar a conformar una identidad pluricultural. Por otro lado, los procesos interculturales implicados en las actividades tampoco son muy significativos para favorecer el desarrollo de la consciencia intercultural del alumno.
La conciencia lingüística en el aula de ELE: lengua artificial, lengua natural y diversidad sociolingüística
Authors: Fernández Martín Patricia
Published: July 2019

El objetivo de este artículo es defender la necesidad de hacer conscientes a los alumnos de español como segunda lengua de dos cuestiones que atañen a la ideología lingüística: por un lado, la distinción entre la lengua artificial (lengua estándar), que es el objeto de aprendizaje del extranjero, y la lengua natural (lengua oral), que es la herramienta de comunicación nativa; y por otro lado, la existencia de facto de una diversidad sociolingüística en España, invisible en los manuales, y cuyo desconocimiento da lugar a múltiples malentendidos. Para ello, comenzaremos en la primera sección analizando los conceptos de «lengua estándar» y «dialecto» en el Marco común europeo de referencia para las lenguas, así como el de competencia sociolingüística, para comprender las bases metodológicas de este documento. Después, argumentaremos los motivos por los que se debería hacer lo que defendemos, es decir, concienciar al alumno tanto de la artificialidad de la lengua que aprende como de la diversidad lingüística española; y terminaremos, antes de las conclusiones, analizando críticamente una unidad didáctica con objetivos sociolingüísticos, que hemos llevado al aula con varios grupos de extranjeros, que vivían en Madrid y asistían a clases de EL2. La principal conclusión pasa por comprender que los estudiantes también tienen prejuicios y que sólo con una buena educación lingüística, apoyada en ejemplos de la vida cotidiana, pueden eliminarse.
Presencia actual de la fonética en el aula de ELE y su reflejo en la enseñanza de la prosodia
Authors: Boquete Martín Gabino
Published: July 2019

Los estudios de fonética en el aula de ELE tradicionalmente han carecido del tratamiento que se merecen. La aplicación de los actuales modelos comunicativos en la enseñanza de lenguas debería haber ayudado a mejorar su presencia y utilización como elemento fundamental para conseguir una buena competencia comunicativa. El propósito de este artículo es comprobar cuál es la situación de la enseñanza de la fonética (concretamente la prosodia) en nuestros días; para ello se realiza un trabajo de investigación con estudiantes y profesores de español, en la Universidad de Alcalá, sobre las preferencias y uso de las diferentes competencias comunicativas, así como las actitudes y creencias de los participantes hacia el estudio la fonética. Así mismo, se examina la tipología de los ejercicios de práctica prosódica y el tratamiento que se da a la fonética en los manuales de ELE disponibles en el mercado. Esta investigación confirma el poco interés que la enseñanza y aprendizaje de la fonética sigue despertando (insignificante en el caso de la prosodia en español), la necesidad de preparación teórica complementaria por parte del profesor y cómo el contacto de los estudiantes con esta disciplina es casi nulo. Esta falta de atención se ve reflejada en los materiales didácticos, en la metodología y en la práctica diaria en el aula de lengua.

Català malparlat. Algunes propostes per a la didàctica de les desqualificacions personals a l’aula de CLE
Authors: Fumadó Abad Maria dels Àngels
Published: July 2019

El presente artículo tiene como primer objetivo reflexionar sobre el aprendizaje de las palabrotas y los insultos en el aula de catalán como lengua extranjera, ya que paradójicamente, a pesar de la gran cantidad de documentos publicados sobre el conocimiento que tienen y el uso que hacen los catalanoparlantes nativos de este ámbito léxico, es prácticamente nulo el material de carácter didáctico pensado para su utilización en las clases de catalán como lengua extranjera.El léxico de la ofensa personal es muy rico y variado; y tiene, además, unas características especiales, puesto que no solo es necesario aprender el significado del insulto o palabra despreciativa, sino que también es imprescindible saber utilizarlos en el contexto y el momento adecuados. La segunda parte del artículo se propone cubrir en parte el vacío didáctico presente en este ámbito didáctico ofreciendo distintos esbozos de actividades pensadas para familiarizar a los alumnos del nivel B2 del MCER con el léxico de los insultos personales en catalán.
Speech and Gesture in Classroom Interaction: A Case Study of Angola and Portugal
Authors: Livingstone Kerwin A.
Published: July 2019

Una de las principales razones por la cual los seres humanos usan el lenguaje es para comunicarse. Sus comunicaciones, sin embargo, no se realizan  de forma mecánica o robótica. Suele haber una sinergia entre el acto de habla y ciertas partes del cuerpo. En la medida que se producen enunciados hablados, se mueven estas partes corporales produciendo así acciones que son visibles, denominadas ‘acciones corporales visibles’. Estas acciones corporales visibles suelen ejecutarse con distintas partes del cuerpo. Se utiliza el término ‘gestos’ para referirse al movimiento de los miembros superiores del cuerpo. Estos gestos están vinculados más directamente con el habla. Sin importar su edad, nacionalidad, cultura, antecedentes o etnia, los seres humanos, cuando hablan, hacen gestos de forma natural y ubicua. Estos movimientos revelan mucho de sus pensamientos, objetivos, creencias e intereses, entre otros. A la luz de lo anteriormente mencionado, esta investigación pretende comparar descriptivamente el habla y el gesto en dos contextos distintos con dos métodos didácticos diferentes (Angola y Portugal). Se revisan unos metrajes de video de los contextos de interacción —con estudiantes adolescentes y profesores— y se lleva a cabo un análisis descriptivo comparativo general. Por medio del software ELAN, se efectúa un microanálisis de 30 segundos de cada uno de los contextos de interacción. Se presentan algunas conclusiones basadas en el estudio realizado.
Exámenes certificativos de ELE referenciados a sistemas externos como el del MCER

La cultura de los exámenes de lenguas referenciados a sistemas de estándares externos se está imponiendo progresivamente en el panorama internacional. El impacto sin precedentes del Marco común europeo de referencia (MCER) ha erigido a este documento en el principal sistema con el que se relacionan los resultados de los exámenes en todo el mundo. Este fenómeno lleva aparejado el reto de la argumentación de la validez y el de la superación de los problemas que presenta el MCER para este tipo de uso, lo cual implica la profesionalización y el compromiso ético de los agentes implicados en el desarrollo y la administración de exámenes.

La información cultural en los diccionarios de ELE (o De cómo ponerle puertas al campo)
Authors: Maldonado González Concepción
Published: July 2019

Este texto pretende transmitir el enorme valor social de la lexicografía. Creemos en el servicio social que como lexicógrafos podemos (y debemos) prestar al mundo. Y creemos que son muchas las posibilidades que tenemos delante si somos capaces de despertar del letargo de varios siglos de tradición, entendida como mera repetición de inercias de trabajo. Queremos abrir una línea de reflexión sobre la enseñanza de español como segunda lengua, con el hilo conductor de la relación entre léxico y cultura, y la plasmación que de esa relación se hace y se puede hacer en corpus y en diccionarios. Si asumimos que todos somos aprendientes de otras lenguas (o de otras variedades de la lengua propia), y si vivimos esta diversidad como una riqueza; si tomamos conciencia de que todos (como profesores, como editores, y como estudiantes) somos preparadores de materiales, y si recogemos en ellos esa diversidad como una riqueza; y si encaramos con ilusión la tarea de ser todos mediadores entre las distintas culturas, y reflejamos esa diversidad de culturas como una riqueza, entonces, y solo entonces, estaremos ayudando a mostrar la diversidad de culturas con normalidad en nuestro quehacer diario en el mundo ELE.
Normas pedagógicas contra normas lingüísticas en la selección del modo en español como L2: interfaz morfológico-semántica
Authors: Garnes Tarazona Inmaculada
Published: July 2019

La selección del indicativo y el subjuntivo en español es una de las áreas más problemáticas para los hablantes nativos de inglés (Terrell et al., 1987; Stokes, 1988). Estas páginas presentan los resultados de un estudio piloto que examina la adquisición de la distinción de modo en español por parte de hablantes nativos de inglés, concretamente se analiza la interfaz morfo-semántica en la selección de subjuntivo. El marco teórico en el que se basa este estudio es la hipótesis de sistemas en conflicto (Rothman, 2008) analizada anteriormente con la distinción aspectual en español. La hipótesis afirma que un sistema de reglas pedagógicas entra en conflicto con la competencia lingüística subyacente del estudiante en el proceso de adquisición de la L2. Los participantes fueron divididos en cuatro grupos: (1) un grupo de estudiantes de español de nivel intermedio; (2) un grupo de estudiantes de español de nivel avanzado; (3) un grupo de hablantes de inglés con español como lengua de herencia; y (4) un grupo de control de hablantes monolingües nativos de español. Todos los participantes completaron dos tareas escritas. Los resultados aportan evidencia de la hipótesis de Rothman en otras áreas de la gramática en las que las reglas pedagógicas difieren de la gramática subyacente de la L2. Los resultados de este estudio apoyan la hipótesis de que las reglas pedagógicas interfieren en la adquisición de la producción de modo en español, pero no evitan la adquisición del rasgo morfo-semántico [± específico].

Posteriormente, se describe qué es un grupo y cómo se caracteriza para, por último, ofrecer reflexiones didácticas, constatar tendencias y proponer ejemplos de actividades de clase.
La enseñanza de la escritura en los cursos de Español como lengua de origen. Reflexiones sobre las prácticas
Authors: Sánchez Abchi Verónica , Menti Alejandra
Published: July 2019

El presente trabajo tiene por objeto identificar y describir la diversidad y la complejidad de las prácticas de enseñanza de escritura que tienen lugar en cursos de español como lengua y cultura de origen (LCO) en Suiza. Para ello, se realizaron entrevistas semiestructuradas a 9 profesores de español LCO, que enseñan en cantones suizo-alemanes y suizo-francófonos. Las preguntas trataban sobre sus prácticas en general, con un énfasis particular en la enseñanza de la escritura: presencia de la producción escrita en el aula; frecuencia de las actividades de escritura, materiales, actividades realizadas para la producción escrita, dificultades y estrategias de remediación. Las entrevistas fueron grabadas y transcriptas literalmente para su posterior análisis. El análisis de las entrevistas puso de manifiesto cómo enseñan a escribir los docentes en los cursos de español como lengua de origen. Asimismo, las respuestas de los docentes permitieron explorar las concepciones de enseñanza subyacentes a las prácticas, como así también los programas de estudio que guían la enseñanza, los contextos y las políticas educativas que las enmarcan.

Comparative analysis of the efficiency of the application of thermal-hydraulic distributor with classical schemes of connecting subscribers
Authors: Smirnov V.V. , Yavorovsky Yu.V. , Sennikov V.V. , Romanov D.O.
Published: July 2019

Analysis of the use of a thermo-hydraulic distributor in district heating schemes showed insufficient study of the mutual influence of the connected circuits, on which the coefficient of hydraulic stability of the heating network depends, and the lack of a comparative analysis of the efficiency of heat supply when using a scheme with a thermo-hydraulic distributor compared to widely used subscriber connection schemes. The purpose of the study is to compare the economic and energy efficiency of the proposed and existing subscriber connection schemes, which is an important task. In laboratory conditions, a wide range of studies have been carried out to study the hydraulic dependence of the contours of the thermo-hydraulic distributor among themselves. Processing of the results was carried out by the method of correlation-regression analysis and mathematical statistics. In a comparative analysis of subscriber connection schemes, methods of physical modeling of thermo-hydraulic modes were used. A comparative analysis showed that the energy efficiency of the scheme with a thermo-hydraulic distributor is higher in heating systems with non-automated subscribers, regardless of the temperature graph of the heating network. When comparing schemes with parallel connection of a hot water heater, it was found that the totality of electricity consumption for coolant circulation and fuel costs for a circuit with a thermo-hydraulic distributor turned out to be less irrespective of the temperature schedule. Statistical research methods confirmed the independence of the circuits and the normal supply of heat to the heating. New solutions have been obtained to increase the hydraulic stability of the centralized heat supply system using a thermo-hydraulic distributor at a heating point – the hydraulic stability coefficient of the heat network during all subscriber operation modes is equal to one. The results of the study can be used in the design of thermal points: the proposed heating system, the consumers of which will provide a stable hydraulic mode; existing heat supply system, the consumers of which must ensure the hydro-stable control of heat.

Published: July 2019

With the development of three-dimensional (3D) printing, many commercial 3D printing materials have been applied in the fields of biomedicine and medical. MED610 is a clear, biocompatible PolyJet material that is medically certified for bodily contact. In this study, the polydopamine (PDA)/hydroxyapatite (HA) coating was added to the printed MED610 objects to evaluate its physical properties, cell proliferation, cell morphology, and alkaline phosphatase expression level. The results show that the PDA/HA coating helps printed objects to enhance the hardness, biocompatibility, and osteogenic differentiation potential. We expect that PDA/HA coatings contribute to the applicability of MED610 in biomedical and medical applications.
Synergistic effect of metformin and fenugreek on the lipid profile of type-II diabetic patients
Authors: Kaur Manmeet , Singh Narinder
Published: July 2019

Background: Fenugreek is a traditional herb which has great relevance in the world since time immemorial due to its multifarious uses. Besides being a rich source of nutrition, it also finds place in the cure of certain pathological conditions. One of its highly beneficial effects is have been observed on the lipid profile of the hyperlipidemic patient. This study was thus undertaken to see the hypolipidemic effect of fenugreek seeds in patients of Type 2 Diabetes Mellitus (DM) as add-on therapy with metformin.Methods: An open-labelled comparative study of 12 weeks duration was conducted on patients (randomly divided in 2 groups of 30 each) of Type 2 DM. Group 1 was given metformin 500 mg twice a day while group 2 was given 500 mg of metformin along with fenugreek seed powder capsule, 1gm thrice a day. Evaluation for fasting lipid profile estimation was done at the beginning and at the end of the study. Student’s t-test (paired and unpaired) was applied for statistical analysis.Results: After 12 weeks of treatment, there was significant improvement in the lipid profile of both the groups. However, group 2, that received fenugreek along with metformin showed statistically greater improvement as compared to group 1 which received only metformin.Conclusions: This study shows the beneficial effects of fenugreek seeds on lipid profile in patients of Type 2 DM and can be used as an add-on therapy with metformin in controlling the lipid profile of Type 2 DM.

Treatment of diaphyseal fractures of tibia with intramedullary interlocking nail
Authors: Kumar B. S. Vijaya
Published: July 2019

Background: The tibia, or shinbone, is the most commonly fractured long bone in the body. A tibial shaft fracture occurs along the length of the bone, below the knee and above the ankle. It typically takes a major force to cause this type of broken leg. Motor vehicle collisions, for example, are a common cause of tibial shaft fractures. In many tibia fractures, the smaller bone in the lower leg (fibula) is broken as well. The objective was to study fracture healing and union rates with closed intra-medullary interlocking nailing.

Methods: Patients of both sexes belonging to adult age group presenting with fracture tibia to Orthopedic Department, Vydehi Institute of Medical Sciences, of are admitted from January 2015 to December 2015.

Results: In the present study maximum number of patients belongs to 18 to 27 years age group (18 cases) followed by 28 to 37 years age group (15 cases), maximum number of patients sustained tibia fracture due to RTA (38 cases) followed by fall (12 cases), maximum number of patients sustained simple tibia fracture (32 cases), followed by type 2 compound tibia fracture (13 cases) and 36 patients had excellent functional results and 8 patients had good functional outcome, while only 4 patients had fair functional outcome.

Conclusions: IM rods are secured within the bone by screws both above and below the fracture. The metal screws and the rod can be removed if they cause problems, but can also be left in place for life. Tibial rodding provides excellent fixation and alignment of the bones.

They are typically sustained in high-impact trauma, such as car crashes, due to the large amount of force needed to break the bone. The objective of the study was to evaluate the functional outcome of fractures of the shaft of the femur treated with closed intra-medullary interlocking nailing.

Methods: The present study was carried out between June 2015 to May 2016 in Orthopedic Department, Vydehi institute of medical sciences and research centre, Bengaluru. Antegrade nailing using the standard intramedullary interlocking nail was performed on 50 cases who presented with shaft fractures of the femur.

Results: In the present study maximum number of patients belongs to 18 to 27 years age group (24 cases) followed by 28 to 37 years age group (12 cases), maximum number of patients sustained femur fracture due to RTA (42 cases) followed by fall (08 cases), maximum number of patients sustained closed/simple femur fracture (40 cases), followed by open / compound tibia fracture (10 cases), 32 patients had excellent functional results and 10 patients had good functional outcome, while only 5 patients had fair functional outcome.

Conclusions: A femur fracture is always considered a medical emergency requiring immediate evaluation and treatment in a hospital. The treatment is largely dependent on the location of the fracture and the pattern and extent of the break.

Published: July 2019

Background: Proximal humeral fractures are commonly presented in the orthopedic practice. The usual method of treatment was conservative in the past. However, the results and functional outcomes were not good. With the development of PHILOS locking plates, the functional outcomes are known to be improved. We in the present study tried to evaluate the functional outcomes of proximal humerus fractures treated with PHILOS plates.

Methods: This prospective study was conducted in all Adult patients with closed two-part and three-part fractures of the proximal humerus, those who have reported within a week of the injury were included in the study. A total of n=30 patients were included in the study based on the inclusion and exclusion criteria. A standard surgical approach with PHILOS plate was used and patients were followed up for 19 to 24 months.

Results: n=30 patients out of which n=16 (53.33%) were males and n=14 (46.67%) were females. The most common age group involved in the fractures was 31-35 years n=9 (30%) of the patients. Most of the patients n=21 (70%) were having Neer's two-part fractures and three-part fractures were found in n=6 (20%) and four part in n=3 (10%). The overall results in the study were 66.67% of patients had excellent results and 16.67% had good results and 10% had poor results.

Conclusions: PHILOS locking plates is a better treatment option for fractures of proximal humerus especially in cases of poor bone quality and comminuted fractures.

O objetivo deste estudo foi avaliar a influência de diferentes métodos para a geração de modelos geométricos em valores de tensões e distrubuições de dentes tratados endodônticamente, utilizando-se uma análise tridimensional de elementos finitos (3D-FEA). Canino superior humano tratado endodonticamente, restaurado com pino de fibra de vidro e coroa metalocerâmica foi escaneado por meio de microtomografia computadorizada e reconstruído tridimensionalmente. Baseadas nas imagens de microtomografia computadorizada, foram gerados 2 modelos geométricos e divididos nos seguintes grupos: grupo GCAD-apenas a dentina radicular foi reconstruída baseada na imagem obtida por meio de microtomografia computadorizada, enquanto as estruturas remanescentes foram geradas por simulação de software de CAD, e grupo GTC-todo conjunto inteiro foi obtido do escaneamento e reabilitado pela microtomografia computadorizada. O carregamento de 180N em 45° do longo eixo do dente foi aplicado na superfície lingual do terço incisal e os modelos foram suportados por um ligamento periodontal fixado nos 3 eixos do sistema cartesiano (x = y = z = 0). Tensões equivalents de von Mises (VMS) foram calculados. Foram encontradas diferenças no valor de tensões e distribuição entre os métodos de geração dos modelos geométricos. A menor razão entre GTC/GCAD foi para o cimento de resinoso e núcleo. Assim, verificou-se que o método de geração do modelo geométrico na análise de elementos finitos influenciou os resultados da pesquisa, sugerindo melhores resultados para o método GCAD.

This work aims to perform the numerical and experimental characterization of CSRR (Complementary Split Ring Resonator) structures in the ground plane of microstrip antennas, for the use in 4G/LTE wireless systems in the 2.5 GHz band. Two geometries for the radiating elements of the antennas were used, the circular and the rectangular ones. Some initial equations were used to design the CSRR structures, followed by a numerical optimization process. This way, numerical and experimental analyzes of the changes in antennas characteristics were carried out, mainly in resonance frequency, bandwidth and radiation pattern. The simulated results were obtained using the commercial software ANSYS, which uses the Moment Method (MoM). The simulated and measured results of the antennas with the CSRR structures printed on their ground plane were compared with those obtained by circular and rectangular patch antennas with a conventional ground plane, we could observe a reduction in their resonant frequency, enabling the miniaturization process.

The Lean philosophy essentially refers to the way in which processes and operations are defined. Within this new concept, we seek to increase value for the customer, reduce parcels that do not add value, simplify processes, reduce cycle time, reduce variability, increase transparency etc. In this context, the present research was developed in the civil construction realm, more specifically in companies that construct vertical buildings, located in the city of João Pessoa. This study aims to perform a diagnosis about the behavior, attitudes and management actions of constructers in relation to the application of the lean construction philosophy. In order to do that interviews were carried out in a group of five constructors, in which we tried to evaluate through forms the engineering point of view, as well as five other stakeholders’. We identified the level of maturity of companies and their managers, regarding the lean behavior in which a larger part of the constructors demonstrated the knowledge about its content, always looking for an application of the lean philosophy in its enterprises.

Physicochemical properties of commercial medical CO2 sorbents Amsorb Plus, Draeger 800, Draeger free, Loflosorb, Sodasorb, Sofnolime, Spherasorb, Ventisorb, as well as of the Russian adsorbent HPI were studied to determine the chemical compositions, textural characteristics, effective protection time with respect to CO2; crushing and attrition resistance of granular sorbents were measured using the SHELL SMS-1471 and ASTM D 4058 96 procedures. The best performance (a high CO2 capacitance, strength) was observed with Draeger 800. The obtained data on operating properties of commercial sorbents and recommendations can be useful for medicine, rescue works, as well as for scientific and production activities when cleaning air mixtures from carbon dioxide is necessary.

The dependence of the selectivity to products of the commercial process for NO hydrogenation in the H2SO4solution on process parameters such as the flow rate of the NO + H2mixture through the reactor, stirring intensity, concentration of the Pt/graphite catalyst in the suspension and temperature was studied. In the process in the mode of external diffusion of the reactant gases, the first or zero order was observed with respect to the catalyst depending on the catalyst concentration in the suspension, the selectivity to the solid products – hydroxylamine sulfates (HAS) and ammonium – being maximal in the transition range. It was shown that the selectivity to HAS increased upon functionalization of the graphite surface with nitrogen-containing groups that led to modifying the adsorbing and catalytic properties of the supported platinum nanoparticles. Specific behavior of platinum catalysts in concentrated suspensions at the limited feeding reactant gases was discussed.

Oligomerization of pent-1-ene is an effective process for synthesis of high-quality environmentally friendly fuel components. Catalytic properties of H-zeolites FAU, OFF, MOR, ВЕА, MTW and MFI were studied for synthesis of pentene oligomers in an autoclave at 110–200 °C. The wide-pore structure of H-Y and H-Beta (18) zeolites and the high concentration of acid sites were established to cause the high oligomerization activity to obtain 97–100 % yields of oligomers. Oligomers obtained over these catalysts comprised, depending on the reaction conditions, 30–73 % dimers, 25–50 % trimers and 2–14 % oligomers with more than three monomer units (n > 3). Fine-pore zeolites (H-ZSM-5) and zeolites with one-dimensional channel systems (H-OFF, H-MOR, H-ZSM-12) were less active to oligomerization of pent-1-ene, decenes being the main reaction products.

The world prevalence of chronic kidney disease (CKD) stages 1 to 5 ranges from 11.7 to 15.1%. Incidence of fractures in patients with CKD stage 5 is 5-fold higher than that in the general population, which is related to mineral metabolism disorders, secondary hyperparathyroidism, and osteoporosis. By damaging multiple organs and systems, CKD triggers a whole pathological cascade. There are hematopoietic abnormalities, cell lineages, direct toxic effect on blood cell elements, with simultaneously increased risk of bleeding and a high and extremely high risk of thrombi formation and thromboembolic complications. Calcium and phosphorus metabolism disorders lead to calcification and mineralization of vasculature, myocardium and heart valves; progressive renal dysfunction affects the course of heart and vessel diseases, aggravating their clinical manifestations. Cardiovascular disorders become the main cause of death of such patients, and the development of pulmonary hypertension is associated with increased morbidity and mortality. At the same time, protein and energy deficiencies do occur, with disturbance of the acid-base balance, water and electrolyte balance; uremic toxins exert unhealthy effects on the gastrointestinal tract. Various extra-renal pathologies, specific pharmacokinetics, regimen and frequency of renal replacement therapy needed to maintain an adequate volume status make it necessary to thoroughly prepare the patients for surgery and define special requirement to perioperative management in arthroplasty. Currently, there are no guidelines on the perioperative management of this patient category. In this review article we consider specifics and particulars of preoperative, intraoperative and postoperative management of the end stage CKD patients during knee and hip replacement arthroplasties.
