Tectono-sedimentary analysis using the anisotropy of magnetic susceptibility: a study of the terrestrial and freshwater Neogene of the Orava Basin
Authors: Łoziński Maciej , Ziółkowski Piotr , Wysocka Anna 
Published: November 2017

Abstract
The Orava Basin is an intramontane depression filled with presumably fine-grained sediments deposited in river, floodplain, swamp and lake settings. The basin infilling constitutes a crucial record of the neoalpine evolution of the Inner/Outer Carpathian boundary area since the Neogene, when the Jurassic-Paleogene basement became consolidated, uplifted and eroded. The combination of sedimentological and structural studies with anisotropy of magnetic susceptibility (AMS) measurements provided an effective tool for recognition of terrestrial environments and deformations of the basin infilling. The lithofacies-oriented sampling and statistical approach to the large dataset of AMS specimens were utilized to define 12 AMS facies based on anisotropy degree (P) and shape (T). The AMS facies allowed a distinction of sedimentary facies ambiguous for classical methods, especially floodplain and lacustrine sediments, as well as revealing their various vulnerabilities to tectonic modification of AMS. A spatial analysis of facies showed that tuffites along with lacustrine and swamp deposits were generally restricted to marginal and southern parts of the basin. Significant deformations were noticed at basin margins and within two intrabasinal tectonic zones, which indicated the tectonic activity of the Pieniny Klippen Belt after the Middle Miocene. The large southern area of the basin recorded consistent N-NE trending compression during basin inversion. This regional tectonic rearrangement resulted in a partial removal of the southernmost basin deposits and shaped the basin’s present-day extent.
Wind tunnel flux comparisons using a phase Doppler interferometer

Published: November 2017

Abstract
It is essential to know the movement of droplets in time and space (i.e. flux) when measuring and/or predicting spray drift in agricultural application. A study was performed to assess the flux measurements of a phase Doppler system against a standard monofilament system in a wind tunnel. The primary objectives of the study were to compare flux from a new phase Doppler system against 1.7 mm cotton and 2.0 mm nylon strings at varying wind speeds (1.4, 4.2, 8.3, 12.5, and 16.7 m · s−1) and spray exposures times (5, 10, 15, 30, and 60 s) with an overarching hypothesis that the active, phase Doppler is able to accurately measure the flux regardless of exposure and spray mass whereas the static string samplers are limited to a maximum retention. The phase Doppler did measure linearly as expected, however strings did not reach a point in which they loss mass; conversely, they appeared to overload with saturation. These findings are believed to be among many variables which influence the variability of previous mass balance studies.
Germanos/Soğukçam: nouvelle inscription paléo-phrygienne dans une aire cultuelle remarquable
Authors: Brixhe Claude , Vottéro Guy 
Published: November 2017

Abstract
Le petit village de Germanos/Soğukçam (au nord d’Eskişehir) a fourni la plus longue inscription paléo-phrygienne actuellement connue, gravée sur un rocher à une extrémité d’une modeste élévation de terrain. A l’autre extrémité, au pied d’un rocher symétrique, ont été trouvés récemment les restes d’une seconde inscription, vraisemblablement très longue elle aussi, mais qui, sans doute gravée sur la paroi rocheuse, semble en avoir été détachée par un séisme: elle est donc fortement endommagée, mais quelques séquences lisibles révèlent un texte sans doute parallèle à celui qui était déjà connu. Indices d’une implantation humaine à proximité.
Effect of hammer peening with tungsten coating on fatigue properties of carbon steel under rotating bending
Authors: Kanchidurai S. 
Published: November 2017

Abstract
In the present study, we investigated the influence of hammer peening (HP) with tungsten carbide surface coating (WCSC) on high cycle bending fatigue performance of the carbon steel (CS) manufactured as specified in Bureau of Indian Standards BIS 2062 steel. Totally there are twenty-four numbers of specimens cast and tested to investigate fatigue performance. Constantly high cycle bending fatigue load (HBFL) were applied for all specimen, different range of bending stress applied to the specimen and the stress ratio maintained as R = 1. Investigation results show there is up to 40 percent of the fatigue life improvement possible by the surface treatments to the CS material. From the research to date the corrosion and pitting corrosion can be treated by modifying the surface layer of the metal by treating different peening methods and coating.
Numerical approximation of BSDEs using local polynomial drivers and branching processes
Authors: Bouchard Bruno , Tan Xiaolu , Warin Xavier , Zou Yiyi 
Published: November 2017

Abstract
We propose a new numerical scheme for Backward Stochastic Differential Equations (BSDEs) based on branching processes.
We approximate an arbitrary (Lipschitz) driver by local polynomials and then use a Picard iteration scheme.
Each step of the Picard iteration can be solved by using a representation in terms of branching diffusion systems, thus avoiding the need for a fine time discretization. In contrast to the previous literature on the numerical resolution of BSDEs based on branching processes, we prove the convergence of our numerical scheme without limitation on the time horizon.
Numerical simulations are provided to illustrate the performance of the algorithm.
The sugar level in divers’ blood in hyperbaric conditions
Authors: Dolatkowski Augustyn , Szczeblewska A. , Łaba Lucjan , Łokucijewski Bogdan 
Published: November 2017

Abstract
The authors examined 104 divers performing dives in water, 14 exposed to simulated conditions in decompression chambers and 11 control subjects. The average blood sugar reading before diving amounted to 100 mg% with readings of 101 mg% after diving, whereas in the control group these readings were 107 and 100 mg% respectively and in the group of simulated dives, 102 before and 106 mg% after the exposure. It was found that the diet applied ensured a sufficiently high level blood sugar level in the subjects to protect them against hypoglycaemia. Further research in decompression chambers is required.

Authors: Pomohaci Marcel , Sopa Ioan Sabin 
Published: November 2017

ABSTRACT
This research aims to evaluate the effects of motor activities on pupils at primary education. The two samples of pupils were divided as follows: the first group, experimental group consisted of twenty-five students with the age between ten and twelve years old, thirteen boys and twelve girls, group which followed a specific program containing agonistic, playful and initiation training in sports games; and the second group, the control group, consisted of twenty-five students with the age between ten and twelve years old, fourteen boys and eleven girls, group that took the classical physical education and sports curriculum. The motor evaluation tests at which the students have been evaluated have been taken over from the national evaluation system: speed running on 50 m, 5x10 m relay race, resistance running, jumping, throw off the oina ball, abdominal force, back force, upper members force, and lower member force. The results showed that the pupils from the experimental group had better performances compared with those from the control group at the final test, indicating the effectiveness of the agonistic, playful and initiation programs in sports games. Differences in the final testing among student groups were significant in all motor tests (p <0.05). Conclusions have shown that the research hypothesis was valid, so we can say that inclusion of programs with agonistic, playful and initiation in sports games can influence in a good way the student’s motor performance at this age.
A Decision Support System Inferring the Genotypes of Seed Trees From Open Pollinated Progenies
Authors: Papageorgiou A. C. , Iliadis L. S. 
Published: November 2017

Summary
The knowledge of the genetic background of seed lots used in forestry operations (i.e., afforestations, reforestations) is important for the evaluation of the future potential of forests to survive under changing environments. An approach to infer the genotype of seed trees from their open pollinated progenies is presented. Sampling difficulties of adult tree tissue make the genetic analysis of seed trees often impossible. The present decision support system (TGDSS - Tree Genotype Decision Support System) allows the reconstruction of the genotypes of the parent population (adult trees) through the analysis of only the genotypes of the progeny generation (seeds). The method consists of three steps, each one representing a specific logical test. The system was tested with data obtained from the genetic analysis of tree populations. The genotypes inferred through the TGDSS and the ones observed in the laboratory were identical. The factors defining the effectiveness of the system are discussed.
ESTUDIO DE LA ESTABILIDAD ESTRUCTURAL DE ÓXIDOS MIXTOS Zn-Al TIPO HIDROTALCITA EN PRECURSORES CATALÍTICOS CoNiMo FRENTE HDS DE TIOFENO
Authors: Alvarez Ruth , Linares Carlos Felipe 
Published: November 2017

Una de las principales fuentes responsable de emisiones atmosféricas tales como: CO, CO2, SO2, NOX, hidrocarburos y partículas suspendidas es la industria petrolera; la cual en sus refinerías utilizan algunos procesos, como el hidrotratamiento, para mitigar la contaminación ambiental originada. En este proceso, se emplean catalizadores a base de Mo soportados en alúmina. Sin embargo, las exigencias ambientales, con el pasar de los años, han sido más altas, trayendo como consecuencia un compromiso en la síntesis y caracterización de nuevos soportes catalíticos más eficientes. Esta investigación se centró en Estudiar la estabilidad estructural de óxidos mixtos Zn-Al tipo hidrotalcita en precursores catalíticos CoNiMo frente HDS de tiofeno, a una temperatura de calcinación de 450ºC. La metodología empleada, radica en dos etapas de calcinación, la primera se impregna el soporte tipo hidrotalcita (HT) sin calcinar con los metales Co, Ni y Mo, luego de impregnar con dichos metales se calcina; la segunda etapa se calcina antes y después de impregnar con los metales. Los resultados obtenidos denotan un excelente comportamiento para los catalizadores con doble etapa de calcinación, siendo los precursores CoMo más efectivos que NiMo, esto puede justificarse por las características fisicoquímicas de las fases de los metales involucrados y de sus vacantes de coordinación.

Actividad contractual de entidades territoriales a la luz de los principios de la contratacion estatal
Authors: Lucas Ortegón Cesar Augusto 
Published: November 2017

La actividad contractual en Colombia es de naturaleza reglada, por lo tanto la objetividad es su principal característica. Si bien en otras ramas del derecho la aplicación de la norma se ha hecho más transversal al incluir otras fuentes como la costumbre y el derecho de los jueces al nivel jerárquico de la ley, en derecho administrativo no se ha dado este fenómeno de manera tan absoluta, en virtud de los principios especiales que lo rigen y que lo convierten en una rama sujeta manifiestamente a la norma. Esta naturaleza reglada, ha obligado a los servidores públicos y a los particulares que ejerzan función pública a sujetar todas sus actuaciones, administrativas y contractuales, a aquello que la Constitución y la Ley les permitan. De allí que conforme al artículo 6 de la Carta, los servidores públicos respondan por infracción de la Constitución y la Ley y además por omisión y extralimitación en sus funciones. Sin embargo, algunas autoridades a nivel local han optado por apartarse de estas disposiciones en el ejercicio de la actividad contractual que desarrollan en uso de sus facultades y atribuciones legales, la cual, deberíaestar encaminada a asegurar la prestación de los servicios públicos, en función del interés general y para el cumplimiento de los fines del Estado, pero que en este contexto se tergiversa su finalidad en la transgresión de los principios y valores normativos quefundamentan el actuar de los servidores públicos.
En el presente artículo se pretende aclarar esta sujeción obligatoria de las autoridades públicas al ordenamiento jurídico superior en ejercicio de sus facultades contractuales y en desarrollo de esta actividad, referenciando la normatividad que rige hoy por hoy lacontratación pública en Colombia y los desafíos que enfrenta la aplicación de esta, en las entidades territoriales frente a la permisividad ciudadana y judicial que ha venido otorgandoa los mandatarios locales facultades exorbitantes como la de constituir cajas menores, sin permiso legal para ello y destinar sus fondos al pago de contratos que no cumplen con los requisitos normativos para su validez.
Propuesta musulmana hacia una base común para el diálogo interreligioso
Authors: González García Alexander 
Published: November 2017

El 13 de octubre de 2007, con ocasión de la fiesta musulmana Eid al-firt Al Mubarak 1428 A.H., líderes y académicos musulmanes enviaron una carta abierta a los cristianos de todo el mundo concerniente el diálogo interreligioso y los derechos humanos. Este comunicado es conocido como “Una palabra común entre nosotros y vosotros”, el cual quiere mostar que el tema del amor a Dios y el amor al prójimo es una idea común en el Islam y en el Cristianismo. Este terreno común proviene de los principios fundamentales de ambas creencias expresados en el Corán y en la Biblia.
En este artículo, se analiza la propuesta musulmana de tener una base en común para el diálogo interreligioso. En primer lugar, se estudia la propuesta dada por los musulmanes en la carta abierta, para luego, destacar los aspectos positivos que esta iniciativa contiene y que pueden ayudar a mejorar las relaciones entre los creyentes. Además, se exploran algunas ambigüedades de la propuesta musulmana las cuales pueden causar dificultades en la construcción de un diálogo fraterno y sincero entre las religiones. Finalmente, se sustenta que la propuesta musulmana debería ser llevada hacia una óptica más inclusiva en el encuentro con otros, que tenga presente a creyentes y no creyentes, con el fin de promover mas ampliamente los derechos humanos.
