Grandes proyectos urbanos latinoamericanos: aportes para su conceptualización y gestión desde la perspectiva del gobierno local
Authors: Cuenya Beatriz 
Published: September 2019

<p>Esta ponencia aborda la problemática de los grandes proyectos urbanos contemporáneos que se difunden en las principales metrópolis latinoamericanas debido al influjo de la globalización. No alude a cualquier tipo de gran emprendimiento, sino a las mega-operaciones de renovación urbana de iniciativa pública, mediante las cuales espacios relegados de la ciudad se transforman en nuevas centralidades. El propósito del artículo es reconocer los procesos contextuales que explican la emergencia de este tipo de emprendimientos y condicionan el rol que ellos juegan en el desarrollo urbano; identificar sus características esenciales y sugerir algunos criterios para encarar su gestión desde la perspectiva del gobierno local. Con esto se trata de contribuir al avance en el conocimiento y en el debate ya iniciado por varios autores y en trabajos propios previos. El análisis se apoya principalmente en la experiencia argentina de grandes intervenciones impulsadas desde la década del 90 y en la experiencia latinoamericana, particularmente en materia de normativa.</p>

Authors: Díaz Orueta Fernando 
Published: September 2019

<p>El artículo analiza las transformaciones de la agenda de gobierno urbano en la ciudad de Valencia durante las dos últimas décadas, tomando como referencia analítica la teoría de los regímenes urbanos. En Valencia una coalición local por el crecimiento ha impulsado un modelo de ciudad caracterizado por el desarrollo de grandes proyectos urbanos y la celebración de megaeventos. Este modelo ha sido puesto en cuestión por una serie de movimientos urbanos que han evidenciado los graves desequilibrios producidos en la ciudad. Por último, y tomando como referencia la nueva situación creada por la recesión económica, el artículo plantea las posibilidades de que se produzca un cambio de régimen urbano en Valencia.</p>

ADAPTIVE POTENTIALITIES OF HYDRO-MECHANICAL COUPLING WITH DIFFERENTIAL DRIVING GEAR
Authors: Бородина Марина , Borodina Marina 
Published: September 2019

For accident free operation of a technological machine it is necessary to protect it against dynamic loads of high intensity. High dynamic loads are often stipulated by an engineering process and during the process of work a frequency of their impact may change in a wide range. In this case the elastic clutches used in the machine driving gear are not always efficient because of resonance phenomena. The design of a hydro-mechanical coupling with a clogged differential driving gear allows controlling clutch stiffness by means of changing parameters of its hydro-system in the course of technological machine operation.
There are carried out investigations of stiffness adaptation potentialities of a hydro-mechanical coupling with a differential driving gear to a changing fre-quency of dynamic load impacts of the technological machine on the basis of a developed simulator of coupling operation dynamics taking into account stress-strain characteristics of the driving gear and processes taking place in the coupling hydro-system. The dependence of a stiffness coefficient of the coupling upon such hydro-system parameters as initial pressure in a hydro-accumulator and liquid consumption.
As a result of numerical computation of coupling dynamic characteristics in the Matlab application program package there are obtained dependencies allowing the definition of rational values of hydro-system parameters at which the amplitude of the dynamic load influencing a driving gear is minimum. There are shown the results of the investigations of the coupling under the analysis on the experimental bench developed specially which confirmed coupling functional working capacity and simulator adequacy.

The application of braking systems with the lo-cation of the executive mechanism directly upon a bogie is a promising trend in domestic brake production and freight car manufacturing on the whole. In the paper a common circuit of a braking rod leverage with the location of cylinders 670V on the bogie of two-axle type 2 and type 3 (RSS 9246-2013) is considered. The investigation carried out in the work is a continuation of works connected with the updating of a braking system developed earlier.
The aim of the work consists in the definition of cylinder rod outlet limits taking into account elastic deformation of all elements of leverage in accordance with the procedure developed and appraised earlier and also the definition of maximum possible thickness of a brake pad used for this circuit in operation. The rod outlet limits obtained will be standard as system transmission ratio is unified, and an elastic constituent will have minimum deviations from the value obtained and depend upon a specific execution of elements.
In this investigation there is used a 3D brake system model developed thoroughly that allows obtaining an elastic deformation value precise enough. Furthermore, data obtained allow defining a maximum operation outlet of rod of the braking cylinder 670V in the system analyzed during car motion on a long steep slope.
On the basis of the investigations carried out there are defined the limits of rod outlet (35…47mm) for the developed common brake system with cylinders 670V that allows using brake pads of maximum width (65+5mm) used in railway freight rolling-stock of the RF. The maximum operation value of rod outlet is obtained during car motion on a steep long slope (63mm) which does not exceed a working stroke of a cylinder (100mm).

Abstract
The demands placed on highly stressed components are constantly increasing. For this reason, components with a higher degree of efficiency are required for the competitiveness of metallic components. Therefore, a comprehensive understanding of the fatigue behavior of metallic materials and components as well as the development of new methods for the reliable calculation of service life are of increasing importance. The fatigue properties of components are multi-parameter sets and are strongly influenced by surface integrity, as surface and near-surface zones are the most stressed regions of a component. Surface integrity is influenced by each individual manufacturing process, its parameters, the process order and the process combination. Due to their high complexity, the influence-cause-effect relationships of process chains have not yet been sufficiently understood. In order to analyze the interactions between manufacturing process chains, their design, variations in material properties, in particular the microstructure and the resulting component properties, specimens were processed with specifically different machining parameters with and without polished surface. The specimens were characterized by different analyzing methods, such as X-ray for residual stress measurements and phase analysis as well as surface characterizations through confocal microscopy. The results from these analytics are used as an input for a semi-empirical model and finite element analysis providing effective stress amplitudes which include factors such as stress concentration and residual stress in order to predict their influence on fatigue life. This additional material information can be used in currently existing short-time procedures or for conventional determined SN curves to expand them to a multi-parameter dataset. The investigations presented in the scope of this paper were performed on specimens made from quenched and tempered steel SAE 4140H (42CrMoS4) machined with various processing parameters.

Abstract
The influence of process parameters on thrust force during the drilling of pure and chemically treated Kevlar reinforced epoxy composites has been investigated. Surface treatment has been carried out to enhance the physical bonding between fiber and matrix. Four different drill bits were used for the investigation: standard twist, core, step cone and candle stick drill. Three speed and feed rates were used for the investigation. Our objective was to find the minimum thrust force during the drilling of pure and chemically treated Kevlar reinforced composite using four different drill bits. Optimization of drilling process parameters was performed using the Taguchi method of L9 Orthogonal Array. We found that among the four drills core and candle stick drills produce a minimum thrust force compared with the twist and step cone drills. Thrust force values produced by a chemically treated specimen is lower than that of a pure composite specimen irrespective of the drill bits used. Chemically treated specimens of the core and candle stick varieties are suitable for lower thrust force and delamination free holes under specified experimental conditions. The significance of feed rate is more important for thrust force during the drilling of composite specimens irrespective of drills.

Published: September 2019

Abstract
The resilience of materials from the notch effect together with subsequent operating life and safety are important factors for the choice of material in industrial manufacture as well as for crash scenarios. The aim of this investigation is to study stress caused by the notch effect for HCT780XD and X5CrNi18-10 at different tensile test strain rates as well as due to various stress concentration factors during a high-speed tensile test. The notch geometries chosen are round, trapezoid, sharp and bore. They are compared to a test specimen without notch. The stress distribution analysis of notches was performed by the finite-element-method (FEM) in order to determine stress concentration factors. The high-speed tensile test was recorded with a high-speed camera. For this purpose, the test specimens were marked with a speckle-pattern, essential for the identification of strain rate via Dantec Dynamics Istra 4D. The influence of the stress concentration rate on parameters like energy, strength and the elongation of break was established and will be reported in the following. The level of the concentration factor leads to negative effects while the strain rate level delivers positive results. On other hand, the stress concentration factor is more important on the parameter than the strain rate. By contrast, Poisson's ratio does not affect the parameters observed.

Published: September 2019

Abstract
Exposure to a hygrothermal environment would cause severe degradation of the mechanism properties of carbon fiber reinforced polymer (CFRP) laminates. The moisture absorption characteristics of T700/3228 CFRP laminates was studied through moisture absorption tests. The effects on the tensile and compression properties of [0]16 and [90]16 specimens under various hygrothermal conditions were comparative analyzed, and the degradation mechanisms of tensile and compression properties were further researched by microstructure characterization. The results show that under dry conditions, matrix strength increases with rising of temperature because of post-curing of epoxy at high temperatures. At 85 % RH (relative humidity), the strength of CFRP laminates decrease entirely with rising temperature because of the thermal and moisture stress generated at the interface. At a water temperature of 70 °C, the proprieties of CFRP laminates decrease severely.

Published: September 2019

AbstractThis paper studies the corrosion inhibition of carbon steel in a 0.51 mol × dm−3sodium chloride solution in the presence of honey. The tests were carried out using the potentiodynamic polarization method, scanning electronic spectroscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and Fourier-transform infrared spectroscopy (FTIR). Electrochemical parameters which indicate the corrosion behavior of the steel in the sodium chloride solution in the absence and in presence of honey were calculated based on the experimental results. It was shown that honey acts as a mixed corrosion inhibitor whose efficiency increases with an increasing concentration. The maximum efficiency of inhibition (77.68 %) was maintained through a 1200 ppm concentration of honey. The adsorption of the tested inhibitor is described by Langmuir's isotherm, and the calculated value of free adsorption energy indicates the physical adsorption of the organic components of honey on the steel surface. The results of the SEM, FTIR and EDX analysis show that the honey covers the steel surface and prevents the influence of the aggressive medium.
Study on Influence of Co-Injection Molding Process on Self-Reinforcing Characteristics of Self-Reinforced Polypropylene Composite via Visualization

Published: September 2019

Abstract
Self-reinforced polymer composites (SRCs), which are fabricated by combining the same type of polymer with different properties into one body, have high specific strength, no interfacial heterogeneity, and ease of recycling. To better understand the relationship between the molding process and mechanical properties of SRCs, the co-injection molding process was used in this study to process SRCs samples. Further, a self-developed visualized experimental device was used to observe the flow of the polymer melt directly during co-injection molding. From the visualization results, it was found that the tensile properties of SRCs are positively correlated with the absolute value of the slopes of the velocity change at lower melt temperature. When the melt temperature increases to a certain degree, the tensile properties of SRCs are much lower than that of lower melt temperature. The shear rate inside the melt flow and the shear rate between the melt and the matrix wall play a major role in the self-reinforcing characteristics of the SRC.

PENGENDALIAN INFLASI DALAM PERSPEKTIF EKONOMI ISLAM
Authors: Kurniawati Fitri 
Published: September 2019

Inflasi merupakan kenaikan tingkat harga umum. Inflasi terjadi disebabkan oleh beberapa hal diantaranya natural inflation, human error inflation, cost push inflation, spiralling inflation, imported inflation. Di Indonesia inflasi terus naik dan kesenjangan social ekonomi makin lebar. Penyebaran inflasi yang terjadi di Indonesia tidaklah merata. Bank Indonesia sebagai otoritas moneter tertinggi di Indonesia memiliki tujuan untuk mencapai dan memelihara kestabilan nilai rupiah. Tujuan dari penelitian ini adalah untuk menganalisis pengendalian inflasi dengan menggunakan instrumen moneter syariah di Lampung dan untuk mengetahui keefektifan instrumen moneter syariah terhadap pengendalian inflasi di Lampung. Berdasarkan dari analisa data diperoleh bahwa Inflasi di Lampung terjadi karena dua sebab yaitu Natural Inflation (Inflasi Alamiah) dan Human Error Inflation (Inflasi karena Kesalahan Manusia). Ada dua jenis kebijakan moneter yang dilakukan di Indonesia, kebijakan ekspansif dan kebijakan kontraktif. Di Lampung pengendalian inflasi menggunakan instrumen moneter syariah masih belum maksimal. Hal ini dikarenakan kurangnya koordinasi dalam pelaksanaannya. SBSN yang ada di Lampung. Berdasarkan hasil penelitian dapat disimpulkan bahwa instrumen moneter syari’ah di Lampung sudah terlihat cukup menggeliatkan perekonomian, hanya saja belum merata. Instrumen moneter syariah terhadap pengendalian inflasi di Lampung masih belum begitu efektif dikarenakan belum meratanya pembangunan yang menggunakan investasi sukuk negara (SBSN) ini. Penelitian ini diharapkan dapat membantu pembaca untuk pemahaman lebih mendalam mengenai pengendalian inflasi melalui instrumen moneter Islam.
