Authors: Irfana Gus Maelan , Hidayati Nurul , Sunarjono Sri
Published: January 2020

Abstract Traffic congestion in the City of Surakarta gave rise to a phenomenal figure among motor vehicle drivers, called the Traffic Control Volunteers or abbreviated as Supeltas. This Supeltas is present on the road to help organize the movement of traffic, as happened at the Surakarta Ganesha Unsignalized Intersection. This study aims to determine the influence of the existence of Supeltas on capacity, degree of saturation, delay, and queuing opportunities that occur at the intersection. The analysis was carried out using the 1997 Indonesian Highway Capacity Manual. The results showed that the intersection without Supeltas had a capacity of 3,114.03 pcu/hour and a degree of saturation of 1.47, while the same intersection but with Supeltas had a capacity of 3,136.81 pcu/hour and a degree of saturation of 1.51. These results indicate that Supeltas has a positive influence on the performance of the intersection. Nevertheless, the degree of saturation in the location increased due to the increase in traffic volume as well as increased capacity. Keywords: unsignalized intersection, intersection performance, intersection capacity, degree of saturation  Abstrak Kemacetan lalu lintas di Kota Surakarta memunculkan sosok fenomenal di kalangan pengendara kendaraan bermotor, yang disebut Sukarelawan Pengatur Lalu Lintas atau disingkat Supeltas. Supeltas ini hadir di jalan untuk membantu mengatur pergerakan lalu lintas, seperti yang terjadi di Simpang Tak Bersinyal Ganesha Surakarta. Penelitian ini bertujuan untuk menentukan pengaruh keberadaan Supeltas terhadap kapasitas, derajat kejenuhan, tundaan, dan peluang antrian yang terjadi di simpang tersebut. Analisis dilakukan dengan menggu-nakan Manual Kapasitas Jalan Indonesia 1997. Hasil analisis menunjukkan bahwa simpang tanpa Supeltas memiliki kapasitas sebesar 3.114,03 smp/jam dan derajat kejenuhan 1,47, sedangkan simpang yang sama tetapi dengan Supeltas memiliki kapasitas sebesar 3.136,81 smp/jam dan derajat kejenuhan 1,51.

Determination of spreading and flow behavior of brazing fillers
Authors: Uhlig Thomas , Sattler Benjamin , Wagner Guntram , Weis Sebastian
Published: January 2020

The development of new brazing fillers requires knowledge about their properties in comparison to well established fillers. Therefore, the determination of the spreading and flow behavior is necessary. By now, different measuring techniques are combined in order to reach a comprehensive understanding of the mechanisms. Especially in case of flux brazing, conventional measuring techniques cannot be used. Due to the industrial demand of application-related experiments, the intended setup should be simple and easily to arrange. This paper deals with the development of a new procedure to determine the spreading and flow behavior of brazing fillers employing flux. The experimental setup, which consists of a commercially available induction heater, equipped with a temperature controller, is mounted inside a gas and vacuum tight chamber. A CCD camera system is used to record the spreading and flow behavior on surfaces as well as inside narrow gaps. The results of experiments using different fillers and base materials are presented. The measurements of the spreading area and the flow velocity under defined conditions allow a quantitative evaluation of the properties of the fillers. Thus, the comparison of different fillers among each other is possible.

Authors: Kostin Walery A. , Grigorenko Georgy M. , Shapovalov Viktor A. , Pikulin Alexandr N.
Published: January 2020

The results of modelling of temperature fields, kinetics of deposition of layers of dissimilar metals and nature of structural transformations in formation of multi-layer structure of 17G1S and 30KhGS steels are presented. Computer modelling was performed using COMSOL Multiphysics software package. The work takes into account effect of temperature on thermal and physical parameters of steels. To increase productivity of additive process the work has studied simultaneous effect of 3 arcs on process of deposit formation, kinetics of structural transformations and diffusion processes of alloying elements redistribution. The calculations show that preheating of the substrate by arc in the beginning of the process before application of deposited material is necessary in order to decrease a stress level between additive deposit and substrate to 50 MPa. It is shown that the time of passing between neighbor arc heat sources shall be kept in 5- 30 s range. It is determined that low power of arc (1 kW) mainly provokes formation of ferrite-bainite structure in the deposit, portion of bainite in which makes 71 %, ferrite 28% and martensite ~ 1%. Application of larger power arc (5 kW) forms in the deposit bainite-martensite structure, portion of bainite in which makes ~  50%, portion of martensite rises up to 40% and that of ferrite to 10%. Increase of arc power results in rise of maximum temperature of liquid pool to 1750-1850 °C, growth of cooling rate to 15 – 25 °C/s , and, as a consequence, increase of martensite portion in the structure of deposited layers.

Published: January 2020

Atmospheric Plasma Spraying (APS) enables deposition of coatings from different materials, including those based on Al2O3 and TiO2. In this work, Al2O3 + 40 wt.% TiO2 coatings were tested. The relationships between mechanical properties, microstructure and spraying parameters (namely: spraying distance and torch scan velocity) were investigated. Commercial -45 + 5 μm powders in agglomerated as- produced state were sprayed onto the stainless steel 1.4301 substrates. The aim of the study was to determine the adhesion, microhardness and roughness of coatings but also to characterize their microstructure. It was observed that coatings sprayed from shorter distance were well melted and revealed good adhesion, but at the same time they were more porous and of lower microhardness than those deposited from the longer spraying distance.

Authors: Czerniejewska Izabela
Published: January 2020

Based on participant observation and ethnographic interviews with Polish women working in kin-dergartens in Norway, this article studies the migrant women’s employment trajectories, including adaptation processes in the workplace and integration into the wider Norwegian society. In this paper, I aim at answering the following questions: How do Polish migrant women go about seek-ing employment in Norwegian kindergartens? How do they adapt to the new work environment? How do they deal with cross-cultural differences in childcare? How did they learn new norms and values within the institutional context of kindergartens? The research indicates that employment in kindergartens was not merely a way to provide for one’s livelihood, but was also a mechanism to establish and develop a closer relationship with members of the Norwegian society, a tool facilitating meaningful connections with the new country.
Primary school students’ argumentation skills: expression of arguments
Authors: Schoroškienė Vaiva
Published: January 2020

This study was conducted to analyze the fourth grade students’ linguistic abilities allowing them to express their arguments in oral and written texts: to determine both the number of presented arguments as well as the level of their elaboration, to characterize the expression of the arguments. The recorded number of participants was 117 fourth-graders from 15 Lithuanian schools. Oral and written texts created by the students were explored in the study. The obtained results revealed that the fourth grade students were able to voice their opinion on at least one argument when they cre-ated an oral or written text on a familiar topic and context. Approximately one-quarter of the study participants were able to present more than three arguments. No significant differences were found between oral and written argumentations with regard to quantity of the arguments. A qualitative analysis of the spoken and written texts indicates that the fourth grade students can use generalized statements (unelaborated secondary statements), they rely on examples and sources. It has also been observed that the study participants’ abilities to develop arguments differ considerably. Their very diverse, even contrasting abilities demonstrate the necessity for developing/updating the curriculum content that would focus more on argumentation.

Published: January 2020

In this paper, I focus on one of the children’s rights, which Janusz Korczak raised in his writings, namely the child’s right to the present day, which I understand as a postulate to appreciate the dignity of a child in its everyday life. My aim in this paper is, therefore, not only to reconstruct and uncover the complexities of this postulate, but also to theoretically embed this concept in pedagogical narratives about the child, and more specifically in anthropology of education and upbringing. In order to achieve this aim, 1. I will describe two paths in thinking about the relationship between human beings and their culture, taking into account especially its temporal dimension. Then I will proceed to 2. the concept of children’s rights in Korczak’s understanding of the child subjectivity; in order to indicate 3. the radical and ethical character of message his thinking.

La detección de valores atípicos en el campo de la minería de datos (DM) y el descubrimiento de conocimiento a partir de datos (KDD) es de gran interés en áreas que requieren sistemas de soporte a la toma de decisiones, como, por ejemplo, en el área financiera, en donde mediante DM se pueden detectar fraudes financieros o encontrar errores producidos por los usuarios. Entonces, es esencial, evaluar la veracidad de la información, a través de métodos de detección de comportamientos inusuales en los datos. Este artículo propone un método para detectar valores que se consideran valores atípicos en una base de datos de datos de tipo nominal. El método implementa un algoritmo global de “k” vecinos más cercanos, un algoritmo de agrupamiento denominado k-means y un método estadístico denominado chi-cuadrado. La aplicación de estas técnicas ha sido implementada sobre una base de datos de clientes que han solicitado un crédito financiero. El experimento se realizó sobre un conjunto de datos con 1180 tuplas, en donde, deliberadamente se introdujeron valores atípicos. Los resultados demostraron que el método propuesto es capaz de detectar todos los valores atípicos introducidos.

Authors: Carrión Diego , Ayo Alex , González Jorge Wilson
Published: January 2020

Stability analysis in electrical power systems is based on the study in dynamic state of the voltage and frequency, since at the moment that there is some contingency it fluctuates drastically due to the primary and secondary controls of the voltage and frequency to the power systems that act on the generators. In order to solve the possible stability problems that may arise in power systems, various techniques have been developed that act on the generating machines for their protection as well as on the loads for the power cut. The present investigation proposes an alternative methodology for load disconnection by low frequency as an option to save the power system from a possible blackout due to instability due to a fall in the frequency, managing to improve the results affected by other improved techniques, the frequency change range, frequency deviation and the effects of demand disconnection. The proposed methodology was tested in the IEEE 14 bus system.

Authors: Pinzón Stanislao , Yánez Stéfany , Ruiz Milton
Published: January 2020

This research shows a heuristic model for the design of scalable and reliable electrical distribution networks. The algorithms presented allow to optimize the location of transformation centers using on their database geographic information systems from which it is possible to define user locations, candidate sites, possible routes for the deployment of the electricity grid and, in general, data for the reconstruction of the scenario. The model employs clustering and triangulation methods, as well as algorithms for creating a minimally expanding tree and the consequent site assignment for transformer placement. After setting the optimal locations for the transformer site, the algorithms compute voltage drops in secondary circuits, required transformation capability, execution times, and coverage achieved. The results obtained are adjusted to the requirements of an actual distribution power grid and show a good performance on the proposed scenario.
Synthesis of neutral lipids in chlorella sp. under different light and carbonate conditions
Authors: Pérez-Pazos Jazmín-Vanessa , Fernández-Izquierdo Pablo
Published: January 2020

Lipids are biomolecules of great scientific and biotechnological interest due to their extensive applications. Microalgae are potential biological systems used in the synthesis of lipids, particularly Chlorella sp., which is characterized by its high lipid content and for having the right profile for the obtainment of biofuel. Lipid production in microalgae is influenced by several physical and chemical factors.

Any modification thereof can cause a stress response represented by changes in synthesized lipid composition, varying from one species to another. This paper evaluates the effect of different light wavelengths, photoperiods and calcium carbonate (CaCO3) supply in lipid synthesis in Chlorella sp. In order to do so, the microalgae was grown in Bold's Basal Medium (BBM) at 20ºC with constant aeration and subject to low blue (470 nm) and red (700 nm) light wavelengths, 0,5 g.L-1 and 1,5 g.L-1 concentrations of CaCO3 and 6-hour light, 18-hour darkness (6:18) and 18-hour light, 6-hour darkness (18:6) photoperiods. The results indicate a higher growth rate for microalgae under red light, 0,5 g.L-1 of CaCO3 and a photoperiod of 6:18.

On the other hand, lipid production is higher under blue light, 1,5 g.L-1 of CaCO3 and an18:6 photoperiod. Analysis by gas chromatography indicate that the fatty acids in the samples are oleic, linoleic and palmitoleic, which are of recognized importance in the biodiesel industry. This suggests that neutral lipid synthesis can be optimized in two stages: first, by promoting growth and subsequently, by inducing lipid production.

Description  of  the main  environmental  factors  that structure phytoplankton  dynamic  in 27  swamps of the Momposina  Depression  located  in the area  of  influence  of  the Cicuco-Boquete  oil field.  Accor- ding to the results, the parameters  that determined the variations in the physics and  chemistry of the water are related to system hydrology, followed by the variables associated with the industrial operation, particularly in relation to chloride content and natural mineralization, which is due to conductivity and alkalinity.

The euglenoids were the most common throughout the study, particularly during low water periods; cyanobacteria density increased in high waters and pennate diatoms in rising water. The lowest average diversity and richness were reported in the systems with the highest domestic and industrial impact as well as in the swamp referenced herein.

Variations in phytoplankton composition were not related to the hydrological periods studied. pH, NO3, conducti- vity and the organic load (BOD5), as well as variables indirectly related to the industrial operation (chlorides and COD) were determining variables. Total hydrocarbons were not a significant variable in the community structure.

Kloroplast genoma ait psbA-trnH IGS bölgesi, en fazla nükleotid dizi farklılığı içeren bölgelerden biri olmasından dolayı barkodlama amacı ile bitkilerde sıklıkla kullanılan bölgelerden biridir. Bu amaçla meşelerde var olan taksonomik problemlerin çözümüne katkı sağlamak ve türler arasındaki filogenetik ilişkileri değerlendirmek adına bu bölge bu çalışmada tercih edilmiştir. İlk olarak psbA-trnH IGS bölgesine ait sekans bilgisi analizler için NCBI’den sağlanılmıştır. Daha sonra bu sekanslar hizalandırılmış ve varyasyon gösteren bölgeler için bir bazın diğerine değişim oranları, transisyon/transversiyon oranları, baz frekansları gibi analizler MEGA X programı kullanılarak yapılmıştır. Son olarak, türlerin birbirleri ile olan filogenetik ilişkilerini değerlendirmek adına Neighbor-joining dendrogram hazırlanmış ve analiz edilmiştir. Bu bölgenin meşe türlerinin seksiyonel ayrımı için yeterli varyasyona sahip olmasına karşın, tür ayrımında ve tanımlamasında sekans varyasyonlarının yetersiz kaldığı görülmüştür. Çalışmanın sonucu olarak psbA-trnH IGS sekansının meşelerde barkodlama amacı ile tek başına yetersiz olduğu, bununla birlikte farklı barkodlama bölgeleri ile kullanımının fayda sağlayacağı önerilmektedir.

Preserving culture is an important aspect of the lives of indigenous people because indigenous people are synonymous with lifestyles that are still guided by local customs. The process of cultural preservation of indigenous peoples is inseparable from the important role of traditional institutions. The role of customary institutions has the potential to determine the behaviour of indigenous peoples in carrying out their traditional traditions or not.

Foucault y Genet. Ética, escritura y subjetividad
Authors: Garrido Rodríguez Natividad
Published: January 2020

El objetivo de este escrito es indagar en la conexión entre la filosofía y la literatura, tomando como núcleo una escritura de sí que se hace notable en el talante del creador literario. Los trabajos de Michel Foucault en torno a la “ética del cuidado de sí” o “estilística de la existencia”, son un punto de partida para reconocer en la creación literaria un espacio estratégico que permite manifestar cómo otra relación con la moral, con la ética y la política es posible. Con relación a ello, las obras del literato francés Jean Genet, ponen a nuestra disposición toda una serie de recursos y estrategias de investigación para adentrarnos en esta posibilidad. Y ello se debe principalmente, a que se hace manifiesto con Genet una escritura comprometida con una imaginación creativa que busca constantemente nuevos espacios de libertad, y que le permiten expresar otra forma de constituirse e interpretar la realidad. Razón por la cual, Genet será tomado en este trabajo como una proyección literaria de la “ética del cuidado de sí”, en el que la escritura se erige como un campo de batalla desde el que oponer resistencia.
