La degradación ambiental de la cuenca endoreica Coy Aike, patagonia Austral, Argentina, y su implicancia en establecimientos agropecuarios.
Authors: Diez Paula , Vázquez Mirian , Grima Daniel 
Published: March 2017

Este trabajo determina los procesos de degradación de la unidad ecológica Matorral de Mata Negra y la disminución de la capacidad de carga producida por la transformación del paisaje en la cuenca endorreica Coy Aike. A partir de la interpretación visual y el análisis de distintos cortes temporales de imágenes satelitales, se caracterizaron cuatro sectores en la cuenca: Laguna, Mata Negra, Vegetación Subarbustiva y Sin Vegetación, siendo los últimos los que presentan mayores evidencias de erosión. La dinámica de la Laguna registró una variación espacial y temporal directamente relacionada con las condiciones meteorológicas, sin embargo, la lengua de erosión asociada no presentó variabilidad. Estas últimas afectan la vegetación natural por la disminución de la disponibilidad de tierras aptas para pastoreo, y ocasionan pérdidas en el valor textil de la lana. El cálculo del costo económico que produce la erosión de los suelos se determinó teniendo en cuenta la receptividad ovina media por hectárea para el área ecológica. En el establecimiento Coy Aikem, las 211 ha de tierra improductiva representan al productor una pérdida económica de 1.925 dólares anuales, no obstante, la gravedad económica estará dada por la cantidad de bajos con potencialidad erosiva, que existan en los establecimientos agropecuarios.
Evaluación espacio-temporal de la contaminación por partículas suspendidas totales en las parroquias del área metropolitana del municipio Maracaibo, Venezuela, 2001-20081

Published: March 2017

Con este estudio se hizo una evaluación espacio-temporal de la contaminación por partículas suspendidas totales en las parroquias del área metropolitana del municipio Maracaibo, durante los años 2001–2008. Con tal propósito, fueron empleados los siguientes datos: los de contaminación por PST (concentraciones promedio anual) registrados por el Instituto para el Control y la Conservación de la Cuenca del Lago de Maracaibo (ICLAM) y las estadísticas demográficas (Censo 2001). A través de Sistemas de Información Geográfica (SIG) se aplicaron métodos de análisis espacial a las diferentes capas. Para el año 2001, el contaminante PST era moderado y se distribuía de forma homogénea en el 98 % de la superficie urbana,coincidiendo con las diferentes densidades poblacionales de las parroquias(alta – media – baja). En el siguiente periodo (2008), la situación se diversifica alcanzando niveles de aire muy contaminado (mayores a 300 μg/m3) ycoincidiendo geográficamente con parroquias densamente pobladas.
Una visión geográfica de los parques urbanos de la ciudad de Tunja, Boyacá, Colombia
Authors: Ruiz Jorge , Parra Edgar , López-Carr David 
Published: March 2017

Las ciudades latinoamericanas crecen y la calidad y el área per cápita de sus parques se reducen, respecto al estudio de esta situación, insumo fundamental para el diseño de políticas públicas urbanas, existen vacíos. La hipótesis nula para este trabajo es que en Tunja los parques urbanos no presentan una adecuada ni homogénea oferta y dotación. En el 2010 se llevó a cabo un inventario de parques en la ciudad, para cada parque se levantó un polígono con un GPS y se registró su equipamiento (sillas, juegos, canchas). Tunja, con apenas 1,34 m2 de estos espacios por habitante, no cumple con el parámetro nacional de 15 m2 , así, nuestra hipótesis se comprueba cierta. En esta ciudad, los parques son, en su mayoría, muy pequeños, agrupados en pocas áreas y con limitada oferta de servicios, además, no se han vuelto a diseñar grandes parques, como en el pasado, persistiendo barrios sin un solo parque, sugiriéndose un revés en la planeación urbana sustentable.
Peran Guru Kristen sebagai Agen Restorasi dan Rekonsiliasi dalam Mengembangkan Karakter Kristus pada Diri Remaja sebagai Bagian dari Proses Pengudusan [The Role of Christian Educator as Agent of Restoration and Reconciliation in Developing Christ-like Character in Adolescence as part of the Sanctification Process]
Authors: Priyatna Novel 
Published: March 2017

<p>Sanctification is a process of maturation to becoming more Christ-like in character after a person experiences regeneration. In the context of adolescent faith development, apart from parents and church clergy, regenerated adolescents also need support from Christian teachers as the agent of restoration in order to restore the image of God in themselves and as the agent of reconciliation in order to restore their relationship with God, others, and themselves all of which have been affected by sin. Christian teachers can function as role models for these adolescents both inside and outside classroom settings. One of the biggest barriers for adolescents to develop a more Christ-like character are their irrational beliefs that influence their thoughts and behaviors. This article will discuss the role of Christian teachers in helping adolescents to become more Christlike in character in their daily life. </p><p><em>BAHASA INDONESIA ABSTRAK: Pengudusan merupakan suatu proses pendewasaan menuju karakter Kristus setelah seseorang mengalami kelahiran baru. Dalam konteks perkembangan iman remaja, selain dari peran orangtua dan pendeta, para remaja yang telah lahir baru membutuhkan dukungan guru Kristen sebagai agen pemulihan untuk memulihkan gambar dan rupa Allah dalam diri mereka dan agen pendamaian untuk memulihkan relasi mereka dengan Allah, sesama, dan diri sendiri yang telah rusak karena dosa. Guru Kristen memiliki peran sebagai teladan bagi para remaja baik didalam maupun diluar konteks kelas. Salah satu hambatan terbesar bagi remaja untuk memiliki dan menghidupi karakter Kristus adalah irrational beliefs mereka yang mempengaruhi pikiran dan perilaku mereka. Artikel ini akan membahas bagaimana peran guru-guru Kristen dalam menolong para remaja untuk memiliki dan menghidupi karakter Kristus dalam kehidupan mereka sehari-hari.</em></p>

Innovative Testing of Mills and Wellhead Freeze Implemented on Offshore High-Rate 10,000 psi Gas Well
Authors: Haymes Robert Dixie , Imtiaz Khalid , Mazzella Carlo 
Published: March 2017

Abstract
A stuck 9⅝-in. 10,000 psi Inconel 925 back pressure valve (BPV) required a specialized testing apparatus to validate the mill design. The 18¾-in. Unihead and compromised BPV mandated an ice plug freeze capable of withstanding a 10,000 psi test as a well control barrier on the high-pressure sour gas well. The development, testing process and field results to mill the BPV and apply the ice plug freeze will be presented.
Mill machine lathe tests were conducted to achieve preliminary cutting structure and the mill profile. The test apparatus simulated milling an 8.635-in. Inconel 925 BPV stuck in a 9⅝-in. Inconel 725 tubing hanger. A test stand with 26-in. outside diameter (OD) casing and 9⅝-in. inner casing were constructed and double wrapped with 500 ft. of ¾-in. helical coil to simulate the freezing of an 18¾-in. Unihead, with 10,000 psi pressure integrity inside the 9⅝-in. tubing.
The rectangular inserts selected during the milling machine tests using one mill design for hanger and BPV created excessive vibrations, high torque, chipped inserts and slow milling. The first test revealed the inability of one mill to cut two materials and profiles in addition to limitations of available milling parameters. The cutting matrix was changed and two distinct mills were designed and specialized for each profile. The test fixture was also modified to enable a broader range of milling parameters and centralization in a robust testing fixture. The two mills successfully milled the required profile in the second test and the optimal milling parameters were obtained.
The ice plug test was performed on a vertical stand of 26-in. OD casing wrapped with helical coil and 9⅝-in. OD inner casing. The annulus and tubing were filled with water and liquid nitrogen free flowed from tanks through a two inch hose. The mass was cooled to minus 70°F with an ambient temperature of 86°F and repeatedly pressure tested to 2,000 psi and 10,000 psi. The test provided positive proof of the ice plug's integrity as a well control barrier for the large diameter application.
The innovative testing for the mill and freeze applications provided needed information for success in the field. A BPV of this size, material and design had never been milled before. This was the first time a freeze of this size and pressure rating had been placed and tested to 10,000 psi. The project highlighted the value of off-site, pre-job validation testing opposed to the on-site trial and error approach, which can prove costly and ineffective.
When should stream water be sampled to be most informative for event-based, multi-criteria model calibration?
Authors: Wang L. , van Meerveld H. J. , Seibert J. 
Published: March 2017

AbstractIsotope data from streamflow samples taken during rainfall or snowmelt events can be useful for model calibration, particularly to improve model consistency and to reduce parameter uncertainty. To reduce the costs associated with stream water sampling, it is important to choose sampling times with a high information content. We used the Birkenes model and synthetic rainfall, streamflow and isotope data to explore how many samples are needed to obtain a certain model fit and which sampling times are most informative for model calibration. Our results for nine model parameterizations and three events, representing different streamflow behaviours (e.g., fast and slow response, with and without overflow), show that the simulation performance of models calibrated with isotope data from two selected samples was comparable to simulations based on isotope data for all 100 time steps. Generally, samples taken on the falling limb were most informative for model calibration, although the exact timing of the most informative samples was dependent on the runoff response. Samples taken on the rising limb and at peakflow were less informative than expected. These model results highlight the value of a limited number of stream water samples and provide guidance for cost-effective event-based sampling strategies for model calibration.

Published: March 2017

Abstract
Technologies for domestic sewage treatment with low excess sludge yield rate and highly efficient biological treatment methods are needed, and the moving-bed biofilm reactor has great promise for meeting this need. To provide technical support for the treatment of typical domestic sewage, this paper provides an estimate of the bacterial diversity in polyvinyl alcohol (PVA) gel beads determined by a 16S-rRNA gene-based polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) approach, proposes a method for reducing the excess sludge yield rate, and describes the startup and continuous operation of the PVA technology. Domestic sewage was treated by a moving-bed biofilm reactor system using PVA gel beads as a biomass carrier. A significant amount of sphalerite, filamentous bacteria and bacillus were observed on the surface and internal structure of the PVA-gel beads by scanning electron microscope. Clostridiaceae bacterium, Alpha proteobacterium, Phenylobacterium haematophilum and Rhodobacter were identified as dominant bacteria strains using 16S-rRNA PCR-DGGE. The active sludge tanks were found to play a significant role in the reduction of excess sludge.
“OS PANKARARU PAULISTANOS” UMA SITUAÇÃO DE EMERGÊNCIA ÉTNICO-IDENTITÁRIA
Authors: Martins Fábio do Espirito Santo 
Published: March 2017

Este trabalho pretende ampliar a compreensão a respeito do contexto de inserção de uma comunidade indígena, a saber, os Pankararu, em uma realidade social bastante antípoda em relação àquilo que o senso comum concebe como o espaço devido às sociedades indígenas. O que neste caso especificamente, é a favela do Real Parque, bairro da zona sul de São Paulo. O trabalho evidenciou a marginalização e a exclusão da cultura indígena da ordem hegemônica da vida social, e a predominância de uma visão marcada pela representação estereotipada sobre os Pankararu e sua cultura. Desafiante, portanto, quando se propõe analisar o modo de vida de uma comunidade indígena em um contexto urbano, em que têm que enfrentar condições precárias de existência e manter suas peculiaridades culturais em um ambiente bastante adverso. Em que a sociedade não indígena espera que equilibrem os elementos tradicionais de sua cultura, convivendo com as características particulares dos grandes centros urbanos. Neste sentido, quaisquer concepções, que pretendam ser, naturalizadas quanto à cultura e idealizadas em relação aos indígenas, virão a constituírem-se como equívocos conceituais significativos e a causar sérios problemas. Já que, a cultura e a tradição são conceitos distantes de algo imóvel, fechado em si mesma. Pois bem, as reflexões apresentadas, possibilitam a visualização de experiências socioculturais concretas, que os processos de recriação e afirmação identitárias ocorridos na modernidade global, necessariamente, propõem novas perspectivas para o entendimento de categorias sociais e conceituais, tais como a identidade e a cultura. Para aí então, se caracterizarem como instrumentos de luta pelo seu reconhecimento como indígenas de fato, por meio de reivindicações políticas que exigem o cumprimento de seus direitos constitucionais, e culturais diferenciados. Além ainda, de tornar bastante claro, as vastas limitações que os órgãos indigenistas do país mantêm em relação à realidade social contemporânea aqui analisada, isto é, a concentração de populações indígenas nas grandes cidades do país.

The article deals with the study of the relation of students of institutes of higher education to the use of amulets, talismans, and charm as artifacts of safety. Artifacts of safety are material symbols the use of which involves improving the efficiency of self-safety. The considered artifacts entered into the system of subjective views of students; they believed in their effectiveness as means of defense and well-being ofthe person. The understanding of the purpose of amulets, talismans, and charms, established in the cultural space, formed the basis of this belief. This belief is rather a kind of social tradition; it presupposes own experience or magical orientation of the personality of the respondents only partially. Defense was the most attributive sphere of activity of the considered artifacts; they also could bring success and happiness. The study showed significant syncretism of students’ representations of the nature and functionality of the artifacts of safety. Their successful differentiation was based on the discrimination of originand the nature of force. Despite the presence of the belief in the artifacts of safety, the overwhelming majority of the students were ready to use them in the present and especially in the future. The students explained the demand for the artifacts of safety in the future by the desire to ensure the protection of children. The authorsdistinguished and interpreted two groups of contradictions: (a) between the declared belief in the efficacy of the artifacts of safety and the subjects’ willingness to use them; (b) between the declared willingness to use the artifacts of safety and their actual use at the present time.

Published: March 2017

The paper brings forward the results of a comparative study of subjective well-being of Chinese students training in institutes of higher education of China and Russia. The works of psychologists focus primarily on the problem of adaptation of foreign students.However, difficulties can arise and provoke stress in senior years of education. It is important to know how Chinese students cope with stress at different stages of training. The level of subjective well-being is a significant indicator of the success of coping with stress.The empirical study involved 366 Chinese students at the age from 19 to 25 years – men and women – first-year and third-year bachelor students of and first-year MA students of institutes of higher education of China and Russia. The Index of Well-Being Questionnaire (A. Campbell et al.), adapted by Yao Chunsheng, He Nailing and Shen Qi [19, 21] was a method of studying the level of subjective well-being.The results of the study showed that the students of institutes of higher education of Russia scored lower in the assessment of their subjective well-being than the students of institutes of higher education of China. The firsts-year MA students trained in China scored higher in the assessment of subjective well-being than the third-year bachelor students. The firsts-year MA students trained in Russian universities scored lower in the assessment of subjective well-being than the thirdyear bachelor students. The authors put forward a hypothesis that, if to compare with students studying in China, a relatively lower subjective well-being of Chinese students trained in Russian institutes of higher education concerned not only difficulties in adapting toconditions of living and studying abroad, but also stress about future employment. This stress was higher in MA students.
