Gestión de las aguas pluviales en entornos urbanos mediante técnicas de Drenaje Sostenible
Authors: Trapote Jaume Arturo
Published: January 2019

El crecimiento de las ciudades provoca modificaciones sustanciales en el ciclo hidrológico natural en entornos urbanos. Con la impermeabilización del suelo -efecto representativo del desarrollo urbano-, se reduce la infiltración y, por consiguiente, aumenta la escorrentía superficial. Los Sistemas Urbanos de Drenaje Sostenible (SUDS) contribuyen a revertir, al menos en parte, estas consecuencias adversas del proceso de urbanización. En el presente trabajo se lleva a cabo un análisis de las implicaciones hidrológico-hidráulicas de la implantación de SUDS en entornos urbanos. A partir del supuesto de la urbanización de un típico sector urbano, se relacionan las disminuciones del coeficiente de escorrentía asociadas a diversos grados de implantación de SUDS, con las correspondientes reducciones del caudal punta y del diámetro del colector que drena la cuenca de estudio, aplicando modelos de cálculo tradicionales, como son el Método Racional y la fórmula de Manning, respectivamente. Asimismo, se ha evaluado la influencia del coeficiente de escorrentía sobre el riesgo de inundación en base a la probabilidad de ocurrencia de un determinado evento de precipitación, según diferentes periodos de retorno. Los resultados obtenidos permiten cuantificar los efectos hidrológico-hidráulicos de la implementación de SUDS en cuencas urbanas, comprobándose que las reducciones porcentuales del coeficiente de escorrentía implican reducciones porcentuales idénticas del caudal de escorrentía generado en la cuenca, que con la reducción porcentual del coeficiente de escorrentía de la cuenca se obtiene una significativa disminución porcentual del diámetro del colector de drenaje y que la reducción porcentual del coeficiente de escorrentía representa una disminución de la probabilidad de ocurrencia de un determinado evento de precipitación, disminuyendo, en consecuencia, el riesgo de inundación.

Authors: Posada David Liliana Rigey
Published: January 2019

El lactosuero es un subproducto de la industria láctea, resultante de la coagulación de diferentes tipos de quesos, se define como la fracción de la leche, que no precipita por la acción del cuajo o por los ácidos, durante el proceso de elaboración. Constituye el 90% de la leche que ingresa al proceso y este compuesto por sustancias como proteínas solubles, lactosa, vitaminas y sales minerales que son de uso y aplicación en la industria alimentaria. El lactosuero es una sustancia de alto valor nutritivo, pero muy contaminante al contacto con el agua y costoso de procesar. Una inadecuada gestión del lactosuero trae asociado un alto impacto medioambiental. Este factor hace relevante implementar diferentes procesos que faciliten esta recuperación. En esta vía toma fuerza la aplicación de tecnologías emergentes de membrana específicamente la nanofiltracion, profundizando en sus características, usos, aplicaciones, tipos de membranas y factores fisicoquímicos a tener en cuenta en el lactosuero a tratar. Se estudia entonces el aprovechamiento y tratamiento de lactosueros a través del uso de la NF en la concentración y desmineralización de estos, la recuperación de lactosa y de otros componentes importantes por su alto valor nutritivo.

Published: January 2019

The mechanical activation of the Ni85.8Fe10.6Cu2.2W1.4 powder mixture in the time intervals of 30-210 min in combination with thermal treatment at 393-873 K resulted in microstructural changes, forming the nanostructured mixture of the same composition but improved magnetic properties. The best result were achieved for mechanical activation during 120 min and thermal treatment at temperatures close to the Curie temperature (693K), enhancing the mass magnetization of the starting powder mixture by about 57%. The microstructural changes, which include the structural relaxation, decrease in free volume, density of dislocation and microstrain, improve structural characteristics of material, enabling better mobility of walls of magnetic domains and their better orientation in applied magnetic field and consequently enabling better mass magnetization of the material. With longer time of milling, the growing stress introduced in the sample undergoes easier relief, relocating stress-relieving processes toward lower temperatures.

Published: January 2019

This paper presents the measurement of the Ab initio molecular dynamics of a Zn-Al-Fe alloy system. The structural and electronic properties of the Zn-Al-Fe alloy at different temperatures are simulated, and the partial density of states, radial distribution function, coordination number, mean square displacement, and diffusion coefficient are obtained. It provides a theoretical analysis of the vacuum separation of Zn-Al-Fe alloys. The simulation results show that when the temperature was 1073 K, the disorder degree of the system was the largest, the diffusion coefficient was 1.29?10?8m2s?1), and the coordination number was 9.48. It means that the Zn-Al-Fe alloy can be separated into its constituent metals easily by vacuum distillation, and that the optimum temperature to achieve this is 1073 K.

Published: January 2019

In this work, the authors propose a method to obtain micro- and nano-structures on the stainless steel mesh (SSM), which showed the potential application for the treatment of water pollution based on its hydrophobicity and oleophilicity. The textured surfaces with the micrometer scale pore array patterns on the SSM are formed by three-beam laser interference lithography. And the nanostructures, such as nanorods, nanowires, and nanoflakes, are obtained on the surfaces of the SSMs after laser irradiation by heating for 70 min at approximately 600 °C under ambient conditions. The results showed that the nanostructures can be easier to grow on the rough surface than the smooth ones. In addition, these nanostructures are also grown on the surfaces of the laser irradiated SSM with the candle soot (LISSM@C). Raman spectrum proves that the nanostructures are α-Fe2O3 and α-Fe2O3/reduced graphene oxide (rGO). The measurement of the contact angle indicates that the oil-water separation can be realized on the LISSM@C after the thermal treatment.

Published: January 2019

Fiber laser was feasible to cut carbon fiber reinforced plastic (CFRP) laminate with high efficiency and particularly meet short cycle time in large-volume vehicle production. Large differences in physical and thermal properties between fiber and resin, however, have been prohibiting the application of fiber laser cutting on CFRP composites. Joining of CFRP parts is mainly dependent on mechanical bolting/riveting, which depends critically on the quality of processed holes. In this study, CFRP laminates used for manufacturing new energy vehicles were employed to investigate the hole quality during fiber laser cutting in continuous wave and pulse modes. Statistical analysis was performed to optimize process parameters to minimize heat affected zone (HAZ) levels. Results indicated that thermal defects including matrix recessing/decomposition and protruding and uncut fibers were prevalent at hole entry and exit irrespective of processing parameters. Low level of laser power (800 W) and linear energy (50 J/mm) together with the pulse mode were preferred to minimize HAZ during fiber laser cutting of CFRP laminates, while the effect of a laser mode was negligible. Tensile strength of samples with open hole (6.0 mm diameter) cut by a fiber laser varied from 131 to 143 MPa, which depended to some extent on HAZ levels. Massive delamination, fiber breakage, and splitting bounds were the main damage/failure modes.

Authors: Pinilla Omar Rodriguez , Ortiz Fernando Díaz , Gómez Carlos , Hurtado M Mikel F
Published: January 2019

Compact Intracloud Discharges (CID) and most of Transient Luminous Events (TLE) are two known microsecond-pulse discharges related to electrical activity of thunderclouds. However, their nature and relationship with other cloud discharges still unclear. Few theoretical models had been proposed to explain the nature of this phenomenon. Some proposed models involved the effects of runaway electron avalanches (REA) and relativistic runaway electron avalanches (RREA) as essential part of the aforementioned discharges. In this work, an initial stage is done to propose new models to explain behavior of CID and TLE. Thus, it is simulated the propagation of a charged particle for a short distance, emulating a supershort avalanche electron beam (SAEB). Specifically, first results presented come from simulating the displacement of a charged particle and finding its fluctuation factor by means of perturbations theory. Other works on this issue has been done using different approaches namely, Feynman integrals with similar outcomes. Perturbation theory is used because in order to allow a future interaction in the model among particles, the terms of the perturbation series can be manipulated using Feynman diagrams. Initial conditions assumed for this work are: unit cell, anisotropic volume and N molecules inside the volume with no interaction. Three relevant conclusions can be exposed from the results, the simulation is coherent with the obtained results using Feynman integrals approach and the equations make possible to predict the amount of photons generated during the avalanche. Finally, it is possible to model charged particle generation through annihilation of variations of electric potential. Future work includes update the model to consider the interaction among molecules and perform experimental validation of the proposed model.

Published: January 2019

Current computer software for designing gear systems have limited flexibility and few offer multiple gearing design options. The objective of this study was to develop an interactive package for the design and analyses of worm gearing mechanisms. The worm gears were designed based on full-depth involute teeth. Mathematical models were developed to compute geometry factors for surface durability of single-enveloping worm gearing cases which were extracted from established American Gear Manufacturers Association (AGMA) standards. Maximum percentage errors from the geometry features, bending loads and wear loads are 0.97%, 3.27% and 1.77% respectively and insignificant. A software capable of computing geometry parameters, bending and wear loads, and selecting appropriate materials for worm mechanisms with good accuracy has been developed.

Published: January 2019

Blends composed of styrene butadiene rubber (SBR) and acrylonitrile-butadiene rubber (NBR) were fabricated by melt blending technique using two-roll mill blend machine. Cis- polybutadiene rubber (CBR) was used as a compatibilizer for enhancing the homogeneity between SBR and NBR phases in blends. Although, no previous reports were found to discuss improving electrical properties of vulcanized SBR/NBR blends using unfilled rubber system (i.e. no fillers incorporated).  Raman spectra and SEM images indicate that a significant compatibility within the rubber matrix is observed, due to using CBR compatibilizer. The effect of SBR/NBR blend ratio on curing characteristics, physico-mechanical properties, and physicochemical properties (e.g. network characteristics and thermodynamic parameters) were studied. SBR/NBR blend showed comparatively better mechanical properties, compared to each other individually rubber system. Curing parameters e.g. Mooney viscosity and hardness were increased, while a reduction in cure time and specific gravity was observed with increasing SBR ratio in blends. Results revealed that increasing SBR resulted in an enhancement of the tensile strength, modulus at 300 % and elongation at break up to 40 phr, and then gradually decreased. The TGA results indicated that SBR/NBR blends were thermally decomposed at a temperature range of 340-520°C. The notable decrease of DC conductivity (σdc) of vulcanized blends is owing to the decrease of NBR, which is a polar portion and is responsible for increasing the conductivity of vulcanized blends. This proved that the targeted industrial applications for vulcanized blends are entirely depending upon SBR/NBR blend in elastomers matrix.
Analysis of Controlled Single-phase Full-Wave Rectifier with RL Load
Authors: Onah Aniagboso John
Published: January 2019

Diodes are popularly used in rectifiers, which convert an ac signal into a unidirectional signal. They produce a fixed output voltage only. However, controlled switches such as thyristors are used to vary the output voltage of a converter by adjusting the delay or firing angle α of the thyristors. Phase-controlled converters are simple, efficient and less expensive. There are both single-phase and three-phase converters depending on the input supply. We also have half-wave and full-wave converters. The half-wave converter has only one polarity of output voltage and current, while for the full converter, the polarity of the output voltage can be either positive or negative. The purpose of this paper is to investigate the operation of the Single-phase full-wave rectifier. Load current for the controlled full-wave rectifier with R-L load can be either discontinuous or continuous. The paper shows how the rectifier transits from discontinuous current operation to continuous current operation.

High availability of industrial plant could only be achieved by adopting best global maintenance practices (computer software). In this research work, a software module was developed using programming tools such as Visual Basic (V.B) 6.0, Structured Query Language (SQL) and Microsoft Access. Operational data were collected from Warri Refinery and Petrochemical Company and was input into the developed software to analyze the plant availability. The performance test results obtained by the software for a five year period (2009-2013) showed that the software developed is consistently close to 100% accuracy. The output result indicates that the plant availability in 2009 is 9.59%; 2010 is 5.75%; 2011 is 7.12%; 2012 is 1.64% and 2013 is 6.30%. This highly fluctuating and low availability of raw material, inadequate maintenance strategies, aging plant and equipment, lack of spare parts stock for preventive and corrective maintenance for emergency, lack of standby (backup) equipment and utility constraints. It was observed that the aforementioned reasons invariably resulted to constant failure of plant availability could greatly be improved by adopting best global maintenance practices which include the deployment of appropriate software tools.
ARCTIC TOURISM: STATE AND PROSPECTS FOR RUSSIA
Authors: Golubchikov Yuriy N. , Kruzhalin Victor I. , Nikanorova Aleksandra D.
Published: January 2019

Tourism is the key factor of human presence in the Arctic region. The number of tourist visits has been growing extensively since the end of XX century. The Arctic region is not regarded only as prospective region for oil and gas industry but now it is also recognized as the region with high potential for tourism development. The research is dedicated to the assessment of the spatial distribution of human presence within the Arctic region on the basis of statistical analysis of population and tourist visits in different parts of the Arctic. Taking into account the uncertainty of regional Arctic borders definition, which are commonly determined in accordance with given purposes and tasks, we assessed the population and tourist visits for the Arctic Zone of the Russian Federation as administrative union as well as for the Arctic region as physic-geographical region.

The growing number of tourists in the Arctic region influences future development prospects of the region. In 2017 the Arctic region with population of 4.3 million people was visited by 10.2 million tourist. While the favorable environmental conditions of Arctic ecosystems exist, the Arctic region should be considered as the source of nature resources for tourism and various recreational activities. Modern technologies enable the development of travel industry in the region, and therefore the industrial paradigm of “conquer” and “utilization” should be replaced with the axiological paradigm of “Arctic beauty” and recreational resource value.
THE APPLICABILITY OF THE SPECIAL ECONOMIC ZONE MODEL OF LOCAL DEVELOPMENT IN THE LIPETSK REGION
Authors: Rostom Gerard R.
Published: January 2019

The model of regional economic development in the Lipetsk region based on the allocation of industry and agriculture production in Special Economic Zones has shown its effectiveness for the development of the whole region. However, this model was helpless to introduce any significant breakthrough changes in the structure of the economy. Currently there has been an attempt to apply the same allocation model to tourism segment objects. It is shown that tourist entities unlike industrial and agricultural have different development imperatives. The main condition for the successful formation and functioning of tourist objects on a territory is their interconnected interaction within a tourist cluster. A tourist cluster can not be created at the only site. Tourist objects of a tourist cluster must be distributed according to tourist destinations and integrated through a well-developed infrastructure in a single functional system. When applying the special economic zone model to a territory it is necessary to make adaptations in accordance to the specifics of the allocated objects. The conclusion is that the application of the same management model for different economy segments needs adjustment. It is also important to distinguish a “Cluster” which is a geographic concentration of interconnected companies and a “Special Economic Zone” which is a territory with economic preferences.

Published: January 2019

Tem-se como objetivo estudar as oscilações do índice de aridez interanual e sua vulnerabilidade à desertificação para a área da bacia do rio Ipojuca.  Utilizaram-se dos cálculos do balanço hídrico, índice de aridez, classificação climática e nível de susceptibilidade, gerando-se o gráfico do índice e variabilidade de clima da área estudada. Os climas registrados na área de estudo foram do tipo Árido, Semiárido seco com níveis de susceptibilidade oscilando entre muito alta e alta. Áreas identificadas com vulnerabilidade à desertificação em razão do índice de menor aridez podem não estar localizadas em áreas degradadas. As áreas que apresentam maior índice de aridez e não são alocadas como processos de vulnerabilidade podem encontrar-se degradadas a ponto de serem consideradas áreas desertificadas. Esta variação poderá ocorrer devido ao uso inadequado do solo e do ambiente em estudo. Quanto maior a precipitação, maior será o índice de aridez, e diante a desertificação, menor será a susceptibilidade. A temperatura influencia na evapotranspiração, pois quanto maior a temperatura, maior a evapotranspiração e, consequentemente, menor o índice de aridez e, portanto maior a susceptibilidade à desertificação.

Being “Other” in Berlin: German Koreans, Multiraciality, and Diaspora
Authors: Kim Helen
Published: January 2019

Germany is considered a relatively recent country where multiraciality has become a recognised phenomenon. Yet, Germany still considers itself a monoracial state, one where whiteness is conflated with “Germanness”. Based on interviews with seven people who are multiracial (mostly Korean–German) in Berlin, this article explores how the participants construct their multiracial identities. My findings show that participants strategically locate their identity as diasporic to circumvent racial “othering”. They utilise diasporic resources or the “raw materials” of diasporic consciousness in order to construct their multiracial identities and challenge racism and the expectations of racial and ethnic authenticity. I explored how multiracial experiences offer a different way of thinking about the actual doing and performing of diaspora.

The present study aims to describe the research skills of university professors at the Universidad Iberoamericana del Ecuador (UNIBE) through emotional intelligence. The research is focused on the quantitative paradigm, through a descriptive study of a population, which was represented by 35 full-time professors of the university. For the collection of data, a survey was applied as the technique, and as an instrument, a questionnaire was used to the teaching population, it is subdivided into the following variables: emotional self-knowledge, emotional self-control, and structured self-motivation. The Likert model is used for responding with a scale of 5 alternatives. To test the reliability of the instrument, a pilot test was applied, giving a value of 0.894 of the Cronbach alpha statistical coefficient. The scales present Kendall's coefficient of agreement presenting as similarity of variables with a value of p = 0.039, congruence (p = 0045), and tendentiousness (p = 0.035). In conclusion, it is established that research competencies are an attitudinal alternative that imply the understanding and transfer of knowledge, as well as emotional values oriented to significantly stimulate the research potential of a university professor. This shows difficulties in terms of the acquisition of research skills, referring to a set of knowledge, skills, behaviors, and values that teachers should use to face their daily academic lives.

This paper examines whether macroeconomic volatilities as perceived by domestic investors in the sub-region have any influence on these outflows taking some selected Heavily Indebted Poor Countries (HIPC) and dataset for the period 1990 to 2012 as the case study. In addition, the study employs a Generalized Autoregression Heteroscedasticity (GARCH) model and Panel Autoregressive Distributed Lag model in its estimation. The outcomes of the econometric investigation, which reflects the current situation in the sub-region, support the view that domestic investors will withdraw their investments and other financial holdings from the domestic economy if they perceived present and future government policies to be volatile. These results suggest that government in HIPC Countries in SSA should focus on stabilising their macroeconomic and political situation if they want to reduce the outflow of domestic capital.

Financial Inclusion plays an important role in terms of economic growth and poverty reduction owing to inequality, therefore, it is a key aspect of public policy in many governments. This study explores those variables that influence financial inclusion in some Latin American countries, through the use of the panel data econometric technique, based on information provided by the World Bank's Global Findex, and the Statistical Yearbook of the World Bank. ECLAC (Economic Commission for Latin America), during the period between 2007 and 2015. The sample includes 7 countries, namely, Argentina, Brazil, Chile, Colombia, Ecuador, Mexico and Peru. The results indicate that financial inclusion has a positive and significant relationship with the value of GDP per capita, such that the greater the income level which families have, the greater will be the participation in the financial system, and consequently, the greater the degree of financial inclusion. On the other hand, the variable public debt, shows that a high level of indebtedness hinders financial inclusion, therefore, its relationship is negative.

Authors: Ahmed Shakil
Published: January 2019

Augmented reality (AR) and virtual reality (VR), a kingdom-of-the-art technology for superimposing information onto the real world, have recently started to have an effect on our everyday lives. In addition, AR and VR have shown a great contribution to advanced construction management in recent years. However, a comprehensive critical review of AR and VR technologies in construction management is absent in the literature. This study provides a comprehensive review of a summary of using potential opportunities of AR and VR to solve a variety of construction management issues effectively and efficiently. This study found that AR is successfully used in construction project scheduling, progress tracking, worker training, safety management, time and cost management, and quality and defects management. VR is effectively used as a visualization tool, worker training technology, safety management tool, and quality and defects management tool. In addition, AR and VR are used for developing a network that allows the possibility of having conferences with those who are geographically far off from each other or the construction site. This study could help to explore the potential fields of using AR and VR technologies in the construction industry effectively as advance time- and cost-saving profitable tools.

Published: January 2019

This paper discusses the hermeneutical perspective of the prohibition for women to become leaders hadith narrated by Abu Bakrah. The factor that became the background of this study is that there are still many people who understand that women are the second creature, namely "konco wingking". So, they are not deserve to be a leader for people. One of the normative bases is the hadith narrated by Abu Bakrah. The textual-literal understanding of the hadith has implications for the role of women in the public sphere so that there needs to be someone who can answer and place women to their proper degree. This study uses a qualitative method with Schleiermacher hermeneutics approach.The results of this research are the Hadith about the ban on women becoming leaders who narrated by Abu Bakrah through grammatical hermeneutics and psychological perspective cannot be applied in General. Thus, there are no restrictions for women today to be a leader for the people because they currently have a different social background when the Hadith it comes.

Objective: The study aimed to evaluate the potential effects of flaxseed in atherogenesis on rabbits submitted to a hypercholesterolemic diet to 0,5% of cholesterol. Methods: The experiment lasted eight weeks and 32 male New Zealand rabbits were randomized into three groups (G1=11, G2=10 and G3=11). All of them received, during the trial period, the diet Nuvilab® increased with 0.5% cholesterol from lyophilized egg. From the 5th to 8th week, in the G2, was added in the hypercholesterolemic diet 8g/kg of crushed flaxseed, totaling an average of 30g/day. The same amount of crushed flaxseed was added since the beginning of the experiment to G3. Blood samples were collected in the beginning and end of the study to analyze total cholesterol, LDL-C, HDL-C and triglycerides. The euthanasia was performed on the sixty-fifth day to remove the aorta. Despite the increase in TC and LDL-C that occurred in the three experimental groups, it was statistically lower in G3. Morphometric analysis of the intima layer showed a statistically significant difference between groups (p=0.030). Results: There was no statistical evidence in immunohistochemical analysis of inflammatory markers. Conclusion: The consumption of crushed flaxseed showed anti-atherogenic effects on the intimal thickening.
