"En tierras bajas" de Herta Müller: mirada crítica hacia las cicatrices de una infancia irrespirable
Authors: García-Hernández Yolanda
Published: March 2017

A través de la mirada y la voz narrativa de una niña rumana, la escritora Herta Müller nos acerca con su ópera prima Niederungen (En tierras bajas) a las cicatrices aún hoy vivas de su propia infancia en un pequeño pueblo ubicado en la región de Timisoara en la época de la dictadura de Nicolae Ceaucescu. Este artículo pretende una aproximación crítica a la recurrente temática centrada en la denuncia del país dejado atrás por la escritora tras su experiencia de exilio a la entonces Alemania occidental en el año 1987. Un análisis crítico de esta primera obra publicada por Müller en lengua alemana nos acerca a la literatura intercultural de la escritora migrante rumano-alemana cuya calidad y trayectoria literaria la hizo merecedora en 2009 del Premio Nobel de Literatura.

Authors: M. A. de Matteis Lorena
Published: March 2017

Se propone una relación entre la productividad del morfema {-nauta} en español y una serie metafórica que, recursivamente, ha visto ampliado su campo de aplicación. Se consideran estudios que abordan los procesos de formación de palabras desde una perspectiva de morfología diacrónica (Rainer 2002; Pharies 2002, 2004), así como el aporte al estudio de la neología de trabajos sobre el valor de la metáfora en la organización del pensamiento y la comunicación cotidiana (Lakoff y Johnson 1980) y que permiten considerar su relación con las representaciones sociales (Rodríguez Salazar, 2007). Las fuentes son escritas y representan distintas variedades de español, con especial atención a la peninsular y la argentina. También se emplearon búsquedas en línea para identificar ejemplos de uso de voces particulares y se consideraron obras lexicográficas (DRAE, DEA, DUE, DVUA, VOX y las que integran el Nuevo Tesoro Lexicográfico de la Lengua Española en línea) como fuentes secundarias.

Authors: Dopico Eduardo , Pevida Dolores
Published: March 2017

The challenges proposed by the knowledge society requires a change of mentality and routines of our students. Consequently, a shift is also needed in the role played by teachers in their education. 34 secondary school teachers from three Spanish high schools, from Ceuta, Madrid and Asturias, working as part of a network, began to introduce project-based learning (PBL) and cooperative learning to facilitate this change. We analyze the correlations between the beliefs and the attitudes of teachers when they were initiating a methodological transition in their patterns of teaching. At the same time, we compare the competencies and strategies related with PBL that 372 secondary school students from these high schools consider being personally important with those who they believe necessary to improve their learning or to be successful with academic requirements.

Authors: Ozsahin Serife , Uysal Dogan
Published: March 2017

This study analyses the effect of financial deepening on economic development in 12 MENA countries for the period between 2000 and 2014. Using three financial deepening indicators which are widely used in the literature, an econometric analysis was conducted through co-integration and estimation methods which take cross-sectional dependence into account. A long-term relationship between variables was revealed with Westerlund (2008) Durbin-Hausman panel co-integration test, and then, long-term coefficients were obtained using Pesaran (2006) CCE (Common Correlated Errors) estimator. Empirical findings point to a positive relationship between financial deepening indicators - domestic credit to private sector, domestic credit provided by private sector, and liquid liabilities of the financial system ratio – and economic development. With this study, it was shown that the domestic credit to private sector causes economic growth for five countries, domestic credit provided by financial sector causes economic growth for one country, and liquid liabilities of the financial system causes economic growth for four countries.
Arithmetic Triangle
Authors: Ferreira Luis Dias
Published: March 2017

The product of the first $n$ terms of an arithmetic progression may be developed in a polynomial of $n$ terms. Each one of them presents a coefficient $C_{nk}$ that is independent from the initial term and the common difference of the progression. The most interesting point is that one may construct an "Arithmetic Triangle'', displaying these coefficients, in a similar way one does with Pascal's Triangle. Moreover, some remarkable properties, mainly concerning factorials, characterize the Triangle. Other related `triangles' -- eventually treated as matrices -- also display curious facts, in their linear \emph{modus operandi}, such as successive "descendances''.

Authors: Zadeh Ali Kalantar , Kashkooli Leila Ilan , Mirzaee Seyed Alireza
Published: March 2017

In recent years, there has been a high demand for high-power inverters. Unlike a rectifier, an inverter with a high-power electronic oscillator is able to convert direct current (DC) into alternating current (AC) in different forms. Regarding this point, the current paper presents an analysis and design of fuzzy logic control (FLC) applied to an inverter of a single-phase voltage source using LC filter and voltage sensor. Also, three modes of inverter voltage non-linear control (back-stepping, sliding and fuzzy modes) have been simulated and compared. The results of simulation indicated that the suggested FLC could attenuate and reduce total harmonic distortion (THD) under linear loading conditions.

Electrodeposition and characterization of palladium nanostructures on stainless steel and application as hydrogen sensor
Authors: Heydari Hamid , Abdolmaleki Abbas , Gholivand Mohammad Bagher
Published: March 2017

Palladium nanostructures have been deposited onto the stainless steel electrode by simple electrochemical deposition method in a buffer solution. The morphology of the synthesized Pd nanoparticles is controllable by deposition potentials because the driving force for various crystal growth mechanisms is merely dependent on applied potentials. The deposited Pd nanoparticles at higher applied potentials showed a cauliflower-like morphology with a nanoscale structure and large surface area. Then, an amperometric hydrogen sensor based on Pd nanoparticles can be constructed. This sensor is based on polymer electrolyte membrane fuel cell (PEMFC) and can be used at the ambient temperature. It is operated in the three-electrode mode that consists of three electrodes (working, counter and reference) and protonated Nafion membrane as proton conducting solid polymer electrolyte (SPE). The steady-state current response is obtained linearly to the concentrations of hydrogen from 50 to 2000 ppm, when a fixed potential of 0.2V is applied to the sensor. Typical factors that influence the performance of the sensor are analyzed and discussed. The simple and inexpensive hydrogen sensor fabricated shows low LOD (10 ppm, based on S/N = 3), wide linear range (50-2000 ppm) and short response time (10-40 s).

Published: March 2017

In this article, forced convective heat transfer of nanofluid flow in a horizontal tube with a square cross-section and 90-degree elbow under heat flux was investigated in a numerical method. The homogeneous nanofluid of aluminum oxide and water (Al2O3) was used as the working fluid. For the numerical solution of continuity, momentum and energy equations, the finite volume method was used. In this study, the effect of Reynolds number and the solid volume fraction and the impact of the elbow on the flow field and the heat transfer rate and pressure drop was investigated. The results were presented in the form of flow and temperature contours and the Nusselt diagrams, which have a good relation with the experimental results, and showed that by increasing the solid volume fraction and Reynolds number, the heat transfer in the elbow increases. Also the concave surface from inside the tubes had a greater impact on heat transfer than the convex surface.

Optimization and minimization of operational costs is one of the most important prerequisites of any engineering project. Rate of penetration is a crucial factor n drilling controlling cost and time of drilling. In the current research, capabilities of single independent intelligent models are employed for developing a hybrid committee machine that can predict bit penetration bit with high accuracy. To get this goal, three single intelligent models, including neural network, fuzzy logic and neuro-fuzzy, are trained. In the second step, the outputs of these models are integrated by imperialist competitive algorithm (ICA). Finally, a linear equation is achieved which gets outputs of single models as inputs and integrate them somehow the final results is closer to the actual value. The developed ICA-based committee machine is tested by 145 real data points gathered from the drilled wells in an oil field. Correlation of actual and predicted value of ROP obtained from committee machine shows that the model predicts ROP with accuracy of 88 percent. Such model can be used for optimization of drilling parameters in future drilling operations.

In seismic design of structures, determination of number and position of braced frames, considering the architectural scheme of projects, is usually confronted by obstacles. Due to this fact, in some cases, selecting the best location and number of braced bays has led to mistakes in determination of their adjacent members (columns) design loads. One of the seismic design requirements of lateral resisting system is to control the columns adjacent to braced bays for load combinations of amplified seismic load, which is a function of over-strength factor of the structure. This research aims to present and introduce the best structural model of number and position of braced frames in a structural system, such as steel moment resisting frame and eccentric braces dual system; because in 3rd revision of Iranian 2800 standard of seismic provision, there are statements and criteria provided only for capacity of moment frame, not for braces. Though the amplified seismic load function is controlled in models which columns are connected to braces in 2 directions, and seismic loads are applied in those 2 directions, number of damage hinges (Exceeding CP) is significantly increased in comparison to the models with straggly braces. As the increase in axial force of these columns leads to decrease in their moment capacity (despite controlling the amplified seismic load provision), columns in dual systems that resist flexure, would be damaged and exceed the collapse threshold much sooner than other columns. This important fact is not presented in Iranian or even American codes and provisions.

Private ownership is the fundamental rights of individuals in the society and having high jurisprudence and legal support. However, in contrast to public interest, administrative agencies can apply to withdraw the property, although there are evidences for the arbitrariness of the legal nature of administrative agencies. It seems that the unilateral obligation of this action is preferred. Expropriation is in contrary to the principles, therefore for health acquisition, the ceremony which is prescribed by lawyer that non-compliance will invalidate the ownership.

In this present article, we bestshot to go one-step forward in order to solve one of the problems teacher hit upon through method expression andconsideration of teaching method for Architectural Design Basics Courses. Some of these issues for investigationinclude, which goals nail down Architectural Design Basics Courses in university teaching system in Iran?What are the methods and approaches for teaching these courses? Which factors shall investigated beforestarting class session? Which factors are effective on learning process? According to methodology, we started todo research through observation and gathering poll of three universities holding three levels of teaching record inarchitecture (University of Tehran, Marlik Institute of Higher Education and FakhrRazi Institute of HigherEducation), we out –and- out ideas of students and professors of these courses. In addition, through introducingmethods to teach architecture lessons which investigated by researchers during recent years, we will put forwardfor solutions to improve teaching in Architectural Design Basics. In this article, we took advantage fromscanning investigation, we applied observation, library study, and questionnaire to congregate information, andwe brought off quality analysis through a grounded theory approach. In concordance with investigation results,one of the success factors for Architectural Design Basics is dramatize many practices which fired up byprofessors through bring into play different teaching methods.
The Relationship between Ethical Justice & Practical Wisdom: Aristotle's and Ghazali's Viewpoints

The theory of justice is one of crucial principles of philosophical and rational principles in all Greek philosophical schools and then in Islamic morality and ethics. A large number of morality philosophers and exegetes use different concepts of justice interchangeably. They do not make any distinction between justice as a perfect virtue and justice as a component of virtues because they mix the true mediocrity with mediocrity of actions. Aristotle and Ghazali are of philosophers who concentrated on this crucial mixture. This study initially analyzes Aristotle's and Ghazali's mediocrity. Then, it highlights the practical wisdom status and examines justice as a perfect virtue from these scholars' viewpoints. Finally, ethical justice and practical wisdom identicality is evaluated.

In recent years, a substantial amount of evidence has pointed to the key role of free radicals and other oxidants as the main culprits for aging and degenerative diseases associated with aging, such as cancer, cardiovascular diseases, cataract, decline of the immune system and brain dysfunctions. The objective of this work was therefore to detect variations in total phenol and flavonoid content, and in antioxidant activity of samples of V. montevidensis. Dried samples were submitted to extraction to obtain the hexane, ethyl acetate and ethanol fractions. Phytochemical prospecting and an analysis of the phenolic content and antioxidant activity was carried out. The data was analyzed according to the mean±standard deviation and submitted to analysis of variance followed by Tukey's test with a significance of (p < 0.05). Flavonoids, tannins, coumarins, terpenoids, steroids, alkaloids and anthraquinones were detected in the samples. The content of total flavonoids varied between 3.18±0,58 and 7.22±0,17 g/100g, while the total phenols ranged from 1.13±0.16 to 18.44±0.21 g/100g. The extracts produced EC50 between 339.75±6.56 and 278.33±23.11 μg/mL.

O óleo de linhaça apresenta diversas propriedades terapêuticas, principalmente devido à presença de ácidos poli-insaturados em sua composição. Para melhor eficácia e/ou aumento da estabilidade de óleos vegetais farmacologicamente ativos, sistemas nanoestruturados são desenvolvidos para veiculação deste tipo de substância. Este estudo objetivou desenvolver e caracterizar sistemas nanoestruturados contendo óleo de linhaça. Foram preparadas nanocápsulas poliméricas e nanoemulsões, avaliando-se duas concentrações de óleo (1,5% e 3,0%) em ambas as formulações e dois polímeros, Poli(ε-caprolactona) e Eudragit® RL100, no desenvolvimento das nanocápsulas. Ambas as formulações apresentaram características adequadas para sistemas coloidais. Em relação às nanoemulsões, houve diferença significativa das características entre as quantidades de óleo, sendo que 1,5% de óleo de linhaça foi a concentração mais satisfatória. Em relação à presença dos polímeros, houve variação apenas dos valores de potencial zeta e pH. Concluindo, as formulações foram consideradas adequadas para o encapsulamento do óleo de linhaça, sendo carreadores promissores para outras substâncias ativas.Descritores: Óleos Vegetais; Óleo de Linhaça; Nanoemulsões; Nanocápsulas Poliméricas.
