Authors: Abbas Ammar Awni 
Published: December 2018

The wide spread of Computer Based Test in the Iraqi universities raised an important concern for some scholars thinking about integrating computers as an academic assessment tool before making big change in the examination systems, that concern is: how the computerized test score is effected in comparison to old paper and pencil . This paper researches whether test scores of Iraqi students varies in the computer, Pencil based tests, sixty-four postgraduate graduates from Iraqi universities. Thirty five female and twenty nine male, all graduated from colleges of science in specializations other than computer science and applying for postgraduate studies in the Iraqi public universities. Therefore are obliged to get the Iraqi computer skills certification for the postgraduate studies, those students chose the computer center in the University of Baghdad to get that certificate. The findings of the study confirmed that postgraduate candidates test scores were not distinctive in the PC based test and in the paper based test, which drove us to presume that PC based testing can be considered as a promising elective method for the logical postgraduate candidates in Iraq.

Published: December 2018

In this study, the ZnTe thin films were deposited on a glass substrate at a thickness of 400nm using vacuum evaporation technique (2Ã—10-5mbar) at RT. Electrical conductivity and Hall effect measurements have been investigated as a function of variation of the doping ratios (3,5,7%) of the Cu element on the thin ZnTe films. The temperature range of (25-200Â°C) is to record the electrical conductivity values. The results of the films have two types of transport mechanisms of free carriers with two values of activation energy (Ea1, Ea2), expect 3% Cu. The activation energy (Ea1) increased from 29meV to 157meV before and after doping (Cu at 5%) respectively. The results of Hall effect measurements of ZnTe , ZnTe:Cu films show that all films were (p-type), the carrier concentration (1.1Ã—1020 m-3) , Hall mobility (0.464m2/V.s) for pure ZnTe film, increases the carrier concentration (6.3Ã—1021m-3) Hall mobility (2m2/V.s) for doping (Cu at 3%) film, but decreases by increasing Cu concentration.

Published: December 2018

In this work, a solid core photonic crystal fibre (SC-PCF) has been designed with endlessly single mode of which both centerd core and holes in the cladding are organized by circles. The designed SC-PCF has a single solid centerd core which is ringed by a six rings hexagonal cladding. The computation of SC-PCF is achieved by using the finite element method (FEM) with perfectly matched layer (PML) boundary condition. All the designed factors like dimensions and distance of both core and cladding areas have varied with an optimized structure. After ending the numerical calculation, the results shows that there are a link between the air hols in the cladding , and the different normalized air hole size.

Published: December 2018

A avaliação contínua e rotineira mantém o estudante sob constante estudo, leitura e aprendizado, além de suavizar o impacto das avaliações teóricas formais sobre os critérios tradicionais de aprovação. O objetivo deste estudo foi avaliar o impacto da aplicação de quiz semanal sobre a nota da avaliação teórica formal no componente curricular Periodontia I do Curso de Odontologia da Universidade Federal do Paraná. Para este estudo observacional retrospectivo, avaliaram-se os campos "nota quiz" e "nota avaliação" dos diários de classe das turmas do primeiro e segundo semestres de 2016, respectivamente “sem quiz" (n=53) e “com a realização de quiz semanal” (n=55). As avaliações teóricas formais foram idênticas para as duas turmas. Os dados referentes ao número de quizzes realizados e média das notas de quiz foram tabulados. As análises estatísticas utilizadas foram teste t de Student e coeficiente de correlação de Spearman. A aplicação de quiz semanal deslocou a curva referente às notas de avaliação teórica à direita, sendo que as notas foram significativamente maiores neste grupo (p<0.01). Além disso, houve correlação significativa entre a nota da avaliação teórica e o número de quizzes realizados por cada estudante (r=0,39; p<0,01), bem como com a média da nota do quiz (r=0,47; p<0,01). Concluiu-se que a utilização de quiz semanal como instrumento de avaliação da aprendizagem influi positivamente no grau de conhecimento adquirido, provavelmente devido a um maior estímulo à leitura e estudo constante.

Considerations on spent fuel behavior for transport after extended storage
Authors: Linnemann K. , Ballheimer V. , Rolle A. , Wille F. 
Published: December 2018

Abstract
Packages for the transport of spent nuclear fuel shall meet the International Atomic Energy Agency regulations to ensure safety under different transport conditions. The physical state of spent fuel and the fuel rod cladding as well as the geometric configuration of fuel assemblies are important inputs for the evaluation of package capabilities under these conditions. In this paper, the mechanical behavior of high burn-up spent fuel assemblies (> approx. 50 GWd/tHM, value averaged over the fuel assembly) under transport conditions is analyzed with regard to the assumptions which are used in the containment and criticality safety analysis. In view of the complexity of the interactions between the fuel rods as well as between the fuel assemblies, basket, and cask containment, the exact mechanical analysis of such phenomena is nearly impossible. Additionally, the gaps in information concerning the material properties of cladding and pellet behavior, especially for the high burn-up fuel, make the analysis more complicated. Considerations and knowledge gaps for the transport after extended interim storage are issues of growing interest. In this context, practical approaches are discussed based on the experience of BAM within the safety assessment of packages approved for transport of spent nuclear fuel.
CIEMAT response to challenges on fuel safety research during dry storage
Authors: Feria F. , Penalva J. , Aguado C. , Herranz L. E. 
Published: December 2018

Abstract
The research on safety of dry stored nuclear fuel poses a number of challenges related to understand and predict its performance under the anticipated conditions. The ultimate goal is the development of analytical capabilities for predicting the integrity of the fuel rod. In this regard, the research carried out by the Unit of Nuclear Safety Research of CIEMAT is enabling the use of predictive tools and analysis methodologies whereby safety conditions can be assessed. To do so, the experience gained in fuel rod thermal-mechanics in reactor is used as a basis; particularly, the fuel performance code FRAPCON is being extended to the dry storage technology, called FRAPCON-xt. This paper shows the work carried out so far, including some applications on aspects related to cladding embrittlement due to hydrides as one of the main concerns.

Published: December 2018

Abstract
Absorbed hydrogen degrades the mechanical properties of zirconium alloys used for nuclear fuel claddings. Not only the total amount of hydrogen absorbed in the cladding tube but also the zirconium hydride orientation and its distribution influence the toughness of the material. For instance, the so-called delayed hydride cracking is caused by the diffusive re-distribution of hydrogen into the dilative elastic strain field ahead of crack tips. The paper presents in-situ and ex-situ neutron imaging investigations of hydrogen uptake, diffusion and distribution in zirconium alloys used for claddings. An overview about results of in-situ experiments studying the hydrogen uptake in strained Zircaloy-4, as well as ex-situ investigations of the diffusion of hydrogen in cold rolled Zircaloy-2 and Zr-2.5 % Nb alloy depending on temperature, rolling direction and thermal treatment and of the hydrogen re-distribution in the β-phase of Zircaloy-4 during a Three-Point-Bending-Test at 600 °C are presented.

Abstract
This paper presents the methodology applied for the experimental and numerical investigation of the mechanical response of spent nuclear fuel rods under static and dynamic loads. The experimental activities were conducted at the JRC Karlsruhe where a 3-point bending test device and an impact tower have been developed and commissioned at the hot-cell facilities. Results are provided for two PWR samples. Load-displacement curves describe the mechanical response of the sample in the 3point bending tests, whereas an image analysis methodology has been developed to comprehend the sample's behaviour under dynamic loads (recorded using a high-speed camera). Finite Element Analysis (FEA) are used to simulate the rod's response based on static and transient structural models in ANSYS Mechanical.
Research activities at GRS on fuel rod behaviour during extended dry storage
Authors: Boldt F. , Kaufholz P. , Péridis M. , Sonnenburg H. G. , Stuke M. 
Published: December 2018

Abstract
As a common part of nuclear waste management strategies, used nuclear fuel is dry stored in casks. After a sufficient time of wet cooling in fuel pools, the fuel assemblies in Germany are dry stored in dual purpose casks mostly on-site until a deep geological repository will be available in the future. In the light of the extended and preliminary not foreseen timescales of up to 100 years of dry storage, open questions arise concerning the long term fuel rod behaviour. Most of these questions are linked to safety criteria e.g. the integrity and fuel encapsulation. Due to the variety of used nuclear fuels and cladding materials in Germany and the additional use of MOX fuels and very high burn-up values of 65 GWd/tHM averaged over a fuel assembly, some of the boundary conditions are unique and specific to the German situation. The GRS has a strong research program to investigate the long term behaviour of fuel assemblies under the German specific conditions of dry storage. Some aspects are presented in the following article.
Open questions on the road to reliable predictions of cladding integrity
Authors: Rowold F. , Hummelsheim K. , Stuke M. 
Published: December 2018

Abstract
The paper at hands discusses the development of an integrated method to predict the fuel rod behavior of LWR-fuel during extended dry storage scenarios. It is well known that degradation effects exist under certain circumstances and that a fuel rod integrity assessment for long-term storage, handling and transport must take these effects into account. It will be elaborated why a complete coverage of the whole lifetime of the fuel rod is necessary. This includes the fabrication, reactor operation, wet storage, drying process, and the dry storage itself. Regarding this approach, a discussion on open questions and challenges will be given.

Como não esquecer de viver o presente: um ensaio sobre a espiritualidade do amor
Authors: Stephan Cassiana Lopes 
Published: December 2018

Pierre Hadot nos mostra, em suas interpretações sobre Goethe e a tradição dos exercícios espirituais, que o amor verdadeiro possui um potencial transformador, pois corresponde a um exercício do espírito capaz de desvelar o ideal que envolve e constitui a realidade dos amantes. Diferentemente, Foucault explica, através de Baudelaire e da cultura da estética da existência, que a experiência transfiguradora do amor propicia a criação do tempo presente como que por ficção e não pela presença do ideal no real. A partir disso, talvez possamos afirmar que a espiritualidade do amor, concebida por Hadot, residiria na eternização do instante presente e na universalização da alma, cuja beleza articula os amantes idealmente à Natureza. Por outro lado, no caso da estética da existência foucaultiana a espiritualidade do amor concerniria à violação ficcional da condição que ata o si, os outros e o mundo à saudade do passado ou à ansiedade pelo futuro. Sendo assim, neste ensaio vislumbramos (a) pontuar as diferenças entre Hadot e Foucault no que concerne à vivência do tempo presente e à espiritualidade do amor para (b) indicarmos de que modo ambos compreenderiam a movimentação histórica do si e dos outros no mundo.
