Authors: Jamil Aneela , Bokhari Tanveer Hussain , Iqbal Munawar , Bhatti Ijaz Ahmad , Zuber Muhammad , Nisar Jan , Masood Nasir
Published: May 2019

In view of promising efficiency of advanced oxidation process (AOP), gamma radiation in combination with H2O2 was employed for the degradation of disperse red 73 (DR73) dye. Cs-137 gamma radiation source was used for dye aqueous solution irradiation. The process variables such as pH (3–9), H2O2 concentration (0.3–0.9 mL), gamma radiation absorbed dose (1–20 kGy) and DR73 initial concentration (50–150 mg/L) were optimized for maximum degradation of dye. The efficiency of AOP was evaluated on the basis of dye degradation, water quality parameters and toxicity reduction. Degradation of DR73 was achieved 69% using gamma radiation absorbed dose of 20 kGy and at the same dose 96.3% degradation was achieved in the presence of 0.9 mL/L H2O2. The dye degradation found to be dependent on dye initial concentration and pH of the medium. The radiolytic progress of DR73 was monitored by Fourier transform infrared (FTIR) and UV-Visible spectroscopy. The chemical oxygen demand (COD) and biological oxygen demand (BOD) were reduced significantly in response of treatment of dye at optimum conditions of process variables. The toxicity of treated and un-treated dye solution was monitored by haemolytic and Ames assays. Results revealed that the toxicity of DR73 dye was also reduced significantly after treatment. Findings revealed that the gamma radiation based AOPs are promising and could possibly be used for the remediation of textile wastewater contains toxic dyes.

Published: May 2019

In this study, a novel type of multi-armed polymer (poyltehylene glycol, PEG) magnetic graphene oxide (GO) composite (GO@Fe3O4@6arm-PEG-NH2) has been synthesized as a support for immobilization of horseradish peroxidase (HRP) for the first time. The loading amount of HRP was relatively high (186.34 mg/g) due to the surface of carrier material containing a large amount of amino groups from 6arm-PEG-NH2, but degradation rate of phenols was also much higher (95.4 %), which is attributed to the synergistic effect between the free HRP (45.4 %) and the support material of GO@Fe3O4@6arm-PEG-NH2 (13.6 %). Compared with the free enzyme, thermal, storage and operational stability of the immobilized HRP improved. The immobilized HRP still retained over 68.1 % activity after being reused 8 times. These results suggest that the multi-armed magnetic composite has good application prospect for enzyme immobilization.

Naturaleza del conocimiento histórico. Su enseñanza y aprendizaje
Authors: Huarte Gabriel
Published: May 2019

La elaboración del articulo responde a las inquietudes despertadas en mi al reflexionar sobre las conclusiones parciales de la reciente investigación que llevé a cabo en el campo de la enseñanza de la Historia en el nivel medio del sistema educativo argentino, convulsionado en los últimos años por los aires de las denominadas "reformas educativas". El trabajo se inicia planteando como disparadores tanto la utilidad o el para qué de enseñar historia, como también analizar someramente la naturaleza de este conocimiento partiendo de la ambigüedad del término que la define. Luego de plantear una breve discusión sobre la preponderancia de las características analíticas o narrativas de este saber a través de su evolución histórica, se intenta una conclusión donde se plantean interrogantes sobre el hoy de la enseñanza de la historia y el desafío que representa para nuestros alumnos adolescentes visitar “ese extraño país llamado pasado".
Democracia y educación: análisis crítico en los albores del tercer milenio
Authors: Guichot Reina Virginia
Published: May 2019

Este articulo está estructurado en tres apartados. En el primero, "Democracia como cultura polítíca"  reflexionamos sobre el significado que hemos de imprimir a tres términos que creemos esenciales dentro de dicho concepto: comunidad, colaboración y participación, pues apreciamos que, con frecuencia, son tergiversados o se aplican significaciones que no responden a su rol en el apuntalamiento de la democracia. En el segundo, "Repensando el término ciudadanía en el Tercer Milenio" se rechaza una concepción de la misma centrada en pensar al ciudadano como un receptor de derechos más que como un actor de la vida comunitaria y se apuesta por una ciudadanla intercultural, que aprecie la riqueza de la pluralidad y la diversidad. Por último, en el epfgrafe "La educación para la ciudadanía democrática. algunas orientaciones", señalamos la necesidad de compromiso de la sociedad en su conjunto en una educación en y para la democracia. En este sentido, presentamos proyectos como el de ciudades educadoras e indicamos algunas líneas de trabajo dentro de las instituciones para conseguir individuos autónomos, libres y responsables en la construcción de un mundo más humano.

Authors: Avdeeva N.N.
Published: May 2019

The article presents research data on the features of interaction between mothers and young children with normal development and with delayed speech development. It was assumed that the differences may manifest themselves in the features of mother-child affection, the nature of emotional and object-practical interaction, as well as in the mothers’ image of their child. The study involved 40 children (20 with normative development and 20 with delayed speech development) and their mothers. The following techniques were used: questionnaire ODREV (by E.I.Zakharova); parent essay "My Child" (incomplete sentences); test of joint activity; a survey for mothers on retrospective assessment of attachment styles; standardized observation of the interaction and affection between the child and the mother. The results of the study showed that the group of mothers and children with normal development mostly demonstrated the secure attachment style. The mothers have an adequate image of their child; show sensitivity, emotional acceptance, ability for positive emotional interaction with the child; emotional communication is in harmony with communication over activities and situations. In the group of mothers and children with delayed speech development the most common is the insecure attachment style; the mothers tend to have inadequate images of their children, reduced sensitivity in interaction, negative feelings, inability to affect the child’s state of mind; disharmony of interpersonal and activity-mediated communication; joint activity is unproductive.
Entre la crisis de criterios y las posibles y nuevas identidades visuales de la arquitectura sacra cristiana
Authors: Jovanoviç Zoran M.
Published: May 2019

Con su estructura, la capilla de Bubanj inicia simultáneamente la reflexión sobre la permanencia y los cambios en la arquitectura del mundo ortodoxo. Su arquitecto se hizo la pregunta de si la iglesia debería recubrirse de oro, con grandes paredes y pilares hechos de piedras preciosas —o de una imitación, como suele ser más habitual—, o si debería enfatizar la simplicidad y la modestia de Cristo. La capilla de Bubanj indica directamente que el creyente debería observar el mundo a través de los ojos del espíritu, algo en lo que insiste la estética del arte eclesiástico bizantino invocado por muchos, pero normalmente solo cuando se indican algunas de las cualidades especiales de la Iglesia ortodoxa, y a la vez, haciendo caso omiso de las leyes de la naturaleza (humana), además de los verdaderos mensajes y lecciones de los Padres de la Iglesia.El concepto de la capilla cercana a Nis ofrece una posible respuesta a la pregunta de si la arquitectura sacra es exclusivamente una cuestión de espiritualidad, es decir: cómo representar un evento sagrado como el momento clave de la creencia íntima (en comunidad). En ese punto, la idea de Sasa Budjevac representa hasta el momento una expresión sin par —en términos del diseño— de las futuras iglesias cristianas, tanto en la Tierra como en la Luna o en otros planetas, como Marte, donde, según la enseñanza de la Iglesia, también reina Dios Kosmokrator.

El reconocimiento de las claves de esta arquitectura debe darnos pistas para la creación de espacios que ayuden a la nueva evangelización en Latino América. La falta de medios materiales no fue óbice para crear esta arquitectura. Para ello se tuvieron en cuenta elementos centrales como pueden ser: la creación del atrio-plaza, lugar de encuentro, la caridad y la educación, la revalorización de la dimensión escatológica del templo cristiano, y las virtudes tanto teologales como cardinales como fuente de inspiración arquitectónica.
Evangelización y comunidad en la posguerra española
Authors: Caballero Zubia Beatriz
Published: May 2019

En 1939 nace el Instituto Nacional de Colonización con el fin de llevar a cabo la construcción de poblados en el medio rural, y posibilitar así la reactivación de un sector agrario que sostuviese la economía de posguerra. No obstante, sus intereses eran tanto económicos, como político-sociales.

Su objetivo era la construcción de nuevos asentamientos que además de regenerar la actividad agraria, fueran el escenario idóneo para una vida rural y al mismo tiempo espiritual. Se trataba de vincular el trabajo del campo a la espiritualización de la vida en comunidad y por tanto la evangelización de los colonos. De este modo, el edificio de la iglesia se convierte en clave dentro de su arquitectura, tanto por su capacidad de representación del sentimiento comunitario, como por su presencia en la trama urbana o su conversión en hito paisajístico a través del campanario.
God Comes Along by Bus

In the aftermath of World War II, twelve million Germans were forced to seek refuge elsewhere in their country. Their sort attracted the attention of Catholic charities such as the Eastern Priests Relief Organization, which provided material and spiritual assistance through a fleet of mobile chapels. This paper claims that this action was a genuinely ‘modern’ form of missionary work in the sense that both its method and message were a child of its time: dwelling on a culture of generalized mobility and mass communication, it spread the word of a triumphalist church claiming moral superiority over other world views, in particular communism. Moreover, the chapel trucks anticipated a fundamental paradigm shift in pastoral care, bringing the church to the people rather than the other way around.
Evangelización en situaciones de emergencia
Authors: Fiorini Bárbara
Published: May 2019

Partiendo de la experiencia personal de diseño y gestión de la construcción de una iglesia temporal realizada a raíz del terremoto que sacudió la región de la Emilia Romagna, este texto, contiene una síntesis de reflexiones sobre los temas de la evangelización en la emergencia que han acompañado el proceso desde la fase de diseño hasta la ejecución. La necesidad inmediata de un refugio y, al mismo tiempo, un lugar donde poderse reconocer como comunidad celebrante, marca la transición desde soluciones al aire libre a espacios definidos, incluso si son temporales como las tiendas de campaña. Pero en el largo plazo, la comunidad percibe claramente la precariedad de la tienda, a la que reconoce un valor para la evangelización en lo provisional, pero no la expresión formal de la iglesia. Busca así un espacio para la celebración de la Eucaristía en el que encontrar, al menos, algunas de los características particulares del lugar de culto que la acerque a la normalidad. De aquí toma forma la iglesia temporal.

Published: May 2019

La Corporación Cultural de Amereida ubicada en los terrenos de la Ciudad Abierta de Valparaíso cuenta con una serie de construcciones de uso religioso, sin embargo, la práctica de la religión también se hace arquitectura mediante otros procesos menos habituales pero igualmente importantes. El objeto de esta comunicación es estudiar tanto los primeros como los segundos con el fin de vislumbrar el papel de la religión tanto en uno como en otros.
Una capilla bajo un puente
Authors: García Morales Soledad , Vela Cossio Antonio
Published: May 2019

La presente comunicación describe la historia de la capilla de santo Domingo de la Calzada, y su última transformación, en 2013, debida a la necesidad de resolver importantes problemas de filtración de agua. La capilla se construyó en 1978 dentro de un túnel de 35 metros de longitud, bajo una via pública. De este hecho se derivaron varios problemas funcionales y litúrgicos. La comunicación describe principalmente cómo, en la rehabilitación de 2013, se han estudiado y resuelto dichos problemas, especialmente los que se refieren al diseño del tabernáculo y el altar.
Perception of Latin America’s church architecture in the time of II Vatican Council
Authors: Vukoszávlyev Zorán
Published: May 2019

Events of World War II resulted in significant social changes from 1945. This is considered to be the main motive behind the attempts for transforming the Catholic sacral space, defining the Christ-centered Church. While in most parts of the Catholic world it was a result of a natural, internal process, these changes didn’t make an effect in the Eastern European countries occupied by the Soviet Union, because religion and religiousness became persecuted under the newly established world order. The political powers professing atheist ideology and communist concepts considered the Church as the main power opponent of their own system. Not only in ideological sense, but also because of the Holy See’s organizational structure that spans state borders. The article interprets the presence of the effects of liturgic reforms, in correspondence with the Eastern politics of the Holy See.
INDONESIAN STUDENT TEACHERS’ CRITICAL THINKING SKILLS IN TEXT ANALYSIS WITH CDA APPROACH
Authors: Ratnadewi Dwijani , Yunianti Sofi
Published: May 2019

Purpose of Study: The present study investigated the impact of critical discourse analysis (CDA) on Indonesian students teachers’ critical thinking skills in their final projects.

Methodology: The study analyzed four final projects of student teachers text analysis. It was a qualitative meta-study applying four stages of Brengtsson'scontent analysis. These student teachers analyzed the world leaders’ political speeches and lawyers’ arguments in court using the CDA approach.

Results: The result of the analysis indicated that 58.3% of the students got the Proficient Level achievement, spreading from the critical skills of communication, analysis (interpretation) and synthesis.

Implications/Applications: The result illustrates that text analysis with CDA devices positively influenced the student teachers’ critical thinking skills. Meanwhile, 75% of them were at low achievement, at the Emergent level, for Reflection (Self-regulating) skills, due to the fact that these students were not accustomed to observing their own analysis.
COMPARISON OF PROCESSES CONSTRUCT CONCEPT OF SOLO THEORY AND APOS THEORY IN MATHEMATICS LEARNING
Authors: Hidayatullah Achmad
Published: May 2019

Purpose of Study: To provide a deep understanding of learning of mathematics, it is necessary to make efforts to realize the conditions of students doing the construction of their understanding. There are many theories that describe thinking in constructing concepts in mathematics. By constructing their understanding, the students can be called doing meaningful learning as mentioned by Ausubel.

Methodology: This research used the comparative process of construct understanding of mathematics with SOLO and APOS theory. SOLO theory (Structure of the Observed Learning Outcome) has five parts namely pre-structural, uni-structural, multi-structural, relational, and extended abstract. While the theory of APOS (Action, Process, object, and Schema). The method used in this research is the study literature from various sources.

Results: This research found the differences construct of the concept in mathematics by using both theories.

Implications/Applications: The SOLO Taxonomic Theory and APOS Theory about its use in constructing mathematical concepts. This means to achieve an individual process needs to do the action repeatedly.
Ethical issues in the early works of accounting
Authors: Garstka Małgorzata
Published: May 2019

Accountants in Poland have recently had the opportunity to celebrate the 20th anniversary of the introduction of the Accounting Act. The act was passed by the Polish Parliament in 1994. 500 years earlier, a treaty on double-entry accounting system was published by Pacioli. The publishing of Tractatus XI. Particularis de computis et scripturis was a momentous event marking the beginning of a new field of economics. Double-entry accounting was in use since Cotrugli introduce it some thirty years before Pacioli published his work.

Recently, in accounting as well as in economics, emphasis has been put on ethics, moral values, and professional attitudes. It is worth considering whether, or to what extent, these were present in the early works of accountancy from 550 years ago and how accountants approached these matters at the beginning of the written history of accounting.

This article presents the main ideas included in the guidelines set by Pacioli and Cotrugli regarding double-entry systems and investigates if ethical guidelines were present there. It turns out that the author of an essential work in the history of accounting, as well as his predecessor, devoted much attention to the moral attitude of the merchant, their appropriate behaviour, their attitude towards customers, and their colleagues and competitors.
On the development of layouts on construction and renovation of marshalling complexes
Authors: Solovyev Sergey , Kabanov Alexander , Zhemchugova Nadezhda
Published: May 2019

Objective: Further improvement of organizational management methods for construction and renovation of railroad stations by the example of marshalling complexes infrastructure. Methods: By means of the methods of continuous construction theory, depending on technological arrangement and structure of facilities of railroad stations, an optimum amount of work was singled out for the purpose of construction lines development. Effective variants of organizational management were selected according to rational coefﬁcient values of combining the facility and specialized ﬂows, in case of which the maximum possible (for conditions of construction and renovation) estimated capacity of the station was preserved. Results: The dependencies of estimated capacity and the amount of work for construction and renovation of marshalling complexes of different types (one-way, combined, etc.) were determined. Practical importance: The data presented in the article is of high practical relevance due to the absence of modern research and industrial regulatory documents on construction and renovation management of the given type of transport facilities.
Mathematical modeling of asynchronous squirrel-cage locomotive propulsion engine
Authors: Khamidov Otabek
Published: May 2019

Objective: To analyze processes in asynchronous engines in case of failure occurrence in rotor winding. Methods: Mathematical model of asynchronous locomotive propulsion engine with cage rotor (AD) was applied. Model calculations applied for the solution of the differential equation system by means of numerical integration were given. Results: The presented AD mathematical model makes it possible to assess the influence of engine’s parameters and load on transient behavior of motor start, as well as to conduct the research in an asynchronous engine in case of balanced and unbalanced operation modes in a three-phase system of coordinates. The latter allow for an adequate description of physics in stator windings in case of failures of rotor bar windings of AD locomotives. Basic equations for the locomotive propulsion engine stator and rotor of different coordinate systems were presented. A structural computational scheme of a three-phase asynchronous engine with a squirrel-cage rotor was developed, making it possible to calculate AD transients. The mathematical model was implemented with MATLAB Simulink software package. Practical importance: The results obtained by means of locomotive asynchronous engine simulation in case of failures of rotor bar windings, as well as AD twisting moment alteration in time demonstrated the possibility of using such a model in order to detect the specific features of failure occurrence in AD.
