ENHANCING VOCABULARY THROUGH CRIMINAL CASE GAME

Technology has its roles in educational field such as it becomes the medium of teaching or learning. Nowadays, the problem that arises is when teachers or learners want to determine the effective way of teaching or learning vocabulary using technology. This study is aimed at finding out whether the fruit of technology like games can be an effective way in learning vocabulary, especially in learning English vocabulary. As Prensky (2002) stated that if someone plays a game, whether he/she wants it or not, learning happens constantly. Previous study from Sorayaie (2012) revealed that games contribute to vocabulary learning if students have the chance to learn, practice, and review English language in a pleasant atmosphere. Based on the previous studies, this study was conducted using Criminal Case game in Facebook as the medium and Vocabulary Knowledge Scale from Wesche and Paribakht (1996) in pre-test and post-tests. There were 30 (thirty) students who participated in this study. The pre-test was conducted one time, while the post-test was conducted two times (two days and two weeks after playing Criminal Case). Descriptive statistics, especially Paired Sample T Test was used to analyze and compare the data. The findings, the result of pre-test and post-tests, showed the significance of game in learning vocabulary and some phenomenon related to the result of the study such as outlier or negative change.
Manufacturing Exports and Employment Generation in Vietnam

This study investigates the effect of export expansion on employment generation in the context of the market-oriented economic reform implemented in Vietnam since the early 1990s. Following a stage-setting survey of manufacturing performance and employment generation in the reform era, it undertakes an empirical analysis using a standard inter- industry input-output framework to examine the contribution of manufacturing exports to job creation, employing Input-Output tables for Vietnam in 2000 and 2007. The findings show that manufacturing exports created about seven million new jobs between 2000 and 2007 through direct effects on the manufacturing sector, as well as through spillover effects across sectors in the overall economy. In particular, export-oriented manufacturing contributed over half of the total increase in manufacturing employment during the period 2000-07. JEL classification : F16, C67
Enhancing container transportation traceability based on intelligent product and web-services: Model driven approach

Containers transportation involves various intermediate supply-chain actors. These containers are subject to myriad risks that can occur at any moment. In addition, the absence of a specialized stakeholder for securing containers flow and the lack of communication among actors impedes identifying responsibilities when an adverse event arises. For this purpose, we advocate the use of traceability system to enhance containers transportation security. This objective is achieved through enhancing systems interoperability to collect necessary information for identifying risks. Thus, we opted for urbanizing a traceability system to meet the new requirements related to risk management. In this paper, we propose the use of web-services to overcome the problems related to the heterogeneity of systems used by supply-chain stakeholders. Thus, we proposed a development process based on model driven architecture (MDA) to automate the code generation of these web-services. Moreover, we used the concept of intelligent product (IP) to propose an intelligent container able to communicate with external systems and to manage information related to its traceability. This solution is validated by a real case study. Key words: Intelligent product (IP), model driven architecture (MDA), service oriented architecture (SOA), business process (BP), traceability.
Mineralogy, Chemistry, and Diagenesis of Tuffs in the Sucker Creek Formation (Miocene), Eastern Oregon

AbstractThe lacustrine Sucker Creek Formation (Miocene) of eastern Oregon includes unaltered vitric tuffs as well as tuffs altered to the following diagenetic fades: (1) bentonite, (2) interbedded bentonite and opal-CT, (3) K-clinoptilolite, and (4) Ca-clinoptilolite. Bentonite beds contain Fe-rich smectite (8–10 wt. % Fe2O3), quartz, plagioclase, and Ca-clinoptilolite. Opal-CT-rich layers contain inorganic silica (opal-CT), Fe-rich smectite, and minor diatoms. K-clinoptilolite beds typically contain clinoptilolite that can be extremely K-rich (≤7.6 wt. % K2O), opal-CT, smectite, plagioclase, and K-feldspar. This diagenetic facies also includes smectitic tuff and unaltered tuff. Ca-clinoptilolite beds contain Ca-clinoptilolite, quartz, K-feldspar, smectite, and illite.Based on its chemistry and mineralogy, the bentonite appears to have been derived from dacitic volcanic ash. Chemical considerations and the close spatial relationship between beds of bentonite and opal-CT suggest that the diagenetic alteration of glass to smectite provided silica to the adjacent opal-CT beds. Based on the presence of late-stage Ca-clinoptilolite, alteration appears to have proceeded in a relatively closed chemical system.Based on the composition of preserved vitric tuff, the zeolitic tuffs appear to be derived from rhyolitic ash, which diagenetically altered in an open hydrologic system and produced vertical zonations in mineralogy. In this model, bentonite horizons at the top of the K-clinoptilolite diagenetic fades formed by reaction of volcanic glass with dilute fluids that had a relatively low (Na+ + K+ + Ca2+)/H+ activity ratio and $${\rm{a}}_{\rm{{H}}_4{\rm{SiO}_4}}$$aH4SiO4 , whereas the underlying K-clinoptilolite beds formed from reactions between glass and dilute fluids having a higher (Na+ + K+ + Ca2+)/H+ activity ratio and $${\rm{a}}_{\rm{{H}}_4{\rm{SiO}_4}}$$aH4SiO4 . Unaltered vitric ash between these beds may represent zones of higher permeability that inhibited secondary mineral alteration. Ca-clinoptilo-lite-rich beds appear to have undergone alteration similar to K-clinoptilolite-rich beds as well as to have been subjected to later, low-temperature (perhaps 75°–150°C) hydrothermal alteration which enhanced cation exchange in the zeolite and formed quartz from opal-CT.
A protocol to develop crack-free biomimetic coatings on Ti6Al4V substrates

Biomimetic coating of titanium and related alloys with carbonated apatitic calcium phosphate is an important area of research in implantology. While this paper specifically refers to coating Ti6Al4V, the results are valid with other related alloys as well. One step in the protocol involves an intermediate alkali treatment of Ti6Al4V to form a sodium titanate layer on the alloy surface. This pretreatment enhances the formation of the coating from simulated body fluid (SBF) solutions. Many papers in the biomimetic coating literature demonstrate the presence of cracks in coatings, irrespective of the SBF compositions and placement of the substrates. The presence of cracks may result in degradation and delamination of coatings. To the best of our knowledge, this issue remains unresolved. Therefore, the aim of this study was: (i) to examine and understand the reasons for cracking and (ii) based on the results, to develop a protocol for producing crack-free apatitic calcium phosphate coatings on Ti6Al4V substrates. In this study, the authors focused their attention on the alkali treatment procedure and the final drying step. It is hypothesized that these two steps of the process affect the crack formation the most. In the first case, the surfaces of alkali-treated substrates were examined with/without water-soaking treatment before immersing in SBF. This water treatment modifies the sodium titanate surface layer. In the second case, two different drying techniques (after soaking in SBF) were used. In one procedure, the coated substrates were dried rapidly, and in the other they were dried slowly. It was observed that the water treatment, irrespective of the drying method, provides a surface, which on subsequent soaking in SBF forms a crack-free apatitic calcium phosphate coating. Based on these results, the authors suggest a protocol incorporating a water-soaking treatment after the alkali treatment and prior to the SBF soaking treatment to obtain crack-free coatings.
FEM-BEM ANALYSIS OF RADIO FREQUENCY DRYING OF A MOVING WOODEN PIECE

The electric field has been computed using the hybrid technique FEM-BEM, so the motion modifies only the boundary conditions on the surface of the wooden piece; FEM mesh inside the piece as well as some of the elements of the matrix associated to the inner nodes remain unchanged. The electric field problem is coupled with the thermal field problem because the complex permittivity depends on the temperature and the specific losses are influenced by the electric field strength. Besides that, the moisturized wood to be dried is moving and the water vaporization has impact on the thermal field. Our paper proposes a method for solving the electric field problem coupled with thermal diffusion and mass problems, taking into consideration the movement of the wood object exposed to the drying process.
Fostering Creativity: A Four Elemental Model of Creative Pedagogy

Capacities and qualities of creativity in teaching for quality learning have been identified by researchers and teaching strategies in fostering children’s creative thinking skills were proposed to create supportive environments in an educational setting. There is little consistent oratory, however, among these insights and strategies concerning different aspects of fostering creativity. In light of this, a fourfold elemental model of creative pedagogy is proposed to offer a more simple and holistic view of fostering and enhancing creativity through teaching to cover the aspect of creative learning affected by psycho-physical environment which was overlooked in the past and to provide a different explanation to some arguments about teaching creativity. This model is also a starting point for studies which intend to understand the teachers and pupils’ and psycho-physical environment responses to creative pedagogy and to provide implications for applying creative pedagogy in an Indian classroom and in Asian context as well.

Stability of downflowing gyrotactic microorganism suspensions in a two-dimensional vertical channel

Abstract Hydrodynamic focusing of cells along the region of the most rapid flow is a robust feature in downflowing suspensions of swimming gyrotactic microorganisms. Experiments performed in a downward pipe flow have reported that the focused beam-like structure of the cells is often unstable and results in the formation of regular-spaced axisymmetric blips, but the mechanism by which they are formed is not well understood. To elucidate this mechanism, in this study, we perform a linear stability analysis of a downflowing suspension of randomly swimming gyrotactic cells in a two-dimensional vertical channel. On increasing the flow rate, the basic state exhibits a focused beam-like structure. It is found that this focused beam is unstable with the varicose mode, the spatial structure, wavelength, phase speed and behaviour with the flow rate of which are remarkably similar to those of the blip instability in the pipe flow experiment. To understand the physical mechanism of the varicose mode, we perform an analysis which calculates the term-by-term contribution to the instability. It is shown that the leading physical mechanism in generating the varicose instability originates from the horizontal gradient in the cell-swimming-vector field formed by the non-uniform shear in the base flow. This mechanism is found to be supplemented by cooperation with the gyrotactic instability mechanism observed in uniform suspensions.
Alpha Stable Distribution Based Morphological Filter for Bearing and Gear Fault Diagnosis in Nuclear Power Plant

Gear and bearing play an important role as key components of rotating machinery power transmission systems in nuclear power plants. Their state conditions are very important for safety and normal operation of entire nuclear power plant. Vibration based condition monitoring is more complicated for the gear and bearing of planetary gearbox than those of fixed-axis gearbox. Many theoretical and engineering challenges in planetary gearbox fault diagnosis have not yet been resolved which are of great importance for nuclear power plants. A detailed vibration condition monitoring review of planetary gearbox used in nuclear power plants is conducted in this paper. A new fault diagnosis method of planetary gearbox gears is proposed. Bearing fault data, bearing simulation data, and gear fault data are used to test the new method. Signals preprocessed using dilation-erosion gradient filter and fast Fourier transform for fault information extraction. The length of structuring element (SE) of dilation-erosion gradient filter is optimized by alpha stable distribution. Method experimental verification confirmed that parameter alpha is superior compared to kurtosis since it can reflect the form of entire signal and it cannot be influenced by noise similar to impulse.
A chromospheric scenario for the activity of β Pictoris, as revealed by FUSE

We investigate a chromospheric scenario to explain the characteristics of the far-UV emission lines of Pictoris, revealed by FUSE spectra of this famous circumstellar disk system. The model assumes a thin region heated up to a few 10 5 K located close to the stellar photosphere. The resonance lines of C III at 977 A and O VI at 1032-1037 A, seen in emission, are produced in this chromosphere-transition region complex. Using complementary data in the mid and near UV (specifically, a resonance doublet of C IV at 1548-1550 A and Mg II h & k), we show that the whole dataset is remarquably well reproduced by the model. In addition, we investigate the properties of the C III* multiplet at 1176 A and conclude that this line likely forms in a weak warm wind, originating from the prominent circumstellar disk of Pictoris. Finally, radiative losses have been calculated and have provided estimates of the amount of non radiative energy dissipated in the external atmosphere of Pictoris, which is a measure of the star's activity level. Such behavior for an A5 V star presents a challenge for both evolution and activity models since the former predict that main-sequence A stars should not be active, while the latter are unable to quantitatively account for the characteristics of the chromospheric heating of Pictoris.
Maximizing multithreaded multicore architectures through thread migrations

Heterogeneity in general-purpose workloads often end up in non optimal per-thread hardware resource usage. The current trend towards multicore architectures, containing several multithreaded cores, increases the need of a complexity-effective way to expose the heterogeneity in general-purpose workloads to the underlying hardware, in order to obtain all the potential performance of these architectures. In this paper we present the Heterogeneity-Aware Dynamic Thread Migrator (hDTM), a novel complexity-effective hardware mechanism that exposes the heterogeneity in software to the hardware, also enabling the hardware to react to the dynamic behavior variations in the running applications. By means of core-to-core thread migrations, the hDTM mechanism strives to perform the desired behavior transparently to the Operating System. As an example of the general-purpose hDTM concept presented in this paper, we describe a naive hDTM implementation for a Power5-like processor and provide results on the benefits of the proposed mechanism. Our results indicate that even this simple hDTM implementation is able to get close to hDTM’s goal, not only avoiding losses due to bad thread-to-core assignments (up to a 25%) but also going beyond the best static thread-to-core assignment upper limit.
The TESSAS Project in Mol: High Temperature Thermal Energy Storage in Saturated Sand Layers with Vertical Heat Exchangers

TESSAS is a European project within the 5 th framework program with three partners: Vito – Belgium, IF Technology – the Netherlands and ZAE – Germany. The main goal of this project was to demonstrate and evaluate an underground storage system in a water saturated sand layer for storing high temperature heat. The TESSASinstallation went in operation in May 2002. It concerns a high temperature borehole storage system that stores waste heat at 90°C from a power plant during summer time. During the heating season, the stored heat is discharged and used directly for heating a building of 3.700 m 2 floor area. A maximum temperature of 70°C was reached in the underground by September, the temperature dropped to 30°C at the end of the heating season. The borehole field is built up of 144 vertical heat exchangers (single U-tubes) at a depth of 30m in order to create a storage volume of approximately 16.000 m 3 . This is the thermal equivalent of a water storage of ten million liter. This system creates many opportunities in combination with solar collector systems, cogeneration or waste heat (power plants, industrial heat residues,…), not only from a technical and ecological standpoint but also from a economical point of view.
Piracy and Competition

The effects of (private, small-scale) piracy on the pricing behavior of producers of information goods are studied within a unified model of vertical differentiation. Although information goods are assumed to be perfectly differentiated, demands are interdependent because the copying technology exhibits increasing returns to scale. We characterize the Bertrand-Nash equilibria in a duopoly. Comparing equilibrium prices to the prices set by a multiproduct monopolist, we show that competition drives prices up and may lead to price dispersion. Competition reduces total surplus in the short run but provides higher incentives to create in the long run.
Molecular Characterisation of some Indian Anthocorid Predators

Anthocorid predators widely used as biocontrol agents were characterised for genetic diversity and phylogeny. Cardiastethus exiguus Poppius, Xylocoris flavipes Reuter and Blaptostethus pallescens Poppius were characterised using Cytochrome oxidase I (COI) marker to elucidate the diversity and phylogeny. The sequencing of the COI region at 650bp was compared with sequence of Orius majusculus (Reuter), available at NCBI by BLASTn. The cluster analysis based on dendogram revealed B. pallescens and O. majusculus to be more closely related, while X. flavipes and C. exiguus were distinct. The usefulness of characterisation and phylogenetic relationship among the anthocorid populations for their effective utilisation in pest management is discussed.
FACTORS INFLUENCING THE ADOPTION OF ELECTRONIC BANKING: EXPANSION OF TECHNOLOGY ACCEPTANCE MODEL (TAM)

For the past decades, many banks and financial institutions around the world have been motivated in implementing electronic banking due to the fast advances in information technology. Despite the significant growth of informatics in banking, electronic banking is still underutilized among banks and other financial institution in Ghana. This study, therefore, enriches the current knowledge on influential factors that affect individual behavioral intention on adopting e-banking. Thus, this study employs Technology Acceptance Model (TAM) in examining the factors that affect person’s behavioral intention in adopting e-banking by expanding it with three other variables which are prior internet knowledge, Information on e-banking and perceived credibility. Survey questionnaire was randomly distributed to a total of 210 respondents who are customers of public and private banks located in Kumasi, Ghana. In all 193 were fully completed representing of 91 percentage. On average, the results indicates that perceived usefulness, perceived ease of use, prior Internet Knowledge, Information on Electronic Banking and Perceived Credibility are significant determinants of customers intention in E-Banking using TAM. This outcome reflects both theoretical and practical consideration in promoting e-banking services in the current competitive industry in Ghana.
Wind Turbine Rotor Simulation via CFD Based Actuator Disc Technique Compared to Detailed Measurement

In this paper, a generalized Actuator Disc (AD) is used to model the wind turbine rotor of the MEXICO experiment, a collaborative European wind turbine project. The AD model as a combination of CFD technique and User Defined Functions codes (UDF), so-called UDF/AD model is used to simulate loads and performance of the rotor in three different wind speed tests. Distributed force on the blade, thrust and power production of the rotor as important designing parameters of wind turbine rotors are focused to model. A developed Blade Element Momentum (BEM) theory as a code based numerical technique as well as a full rotor simulation both from the literature are included into the results to compare and discuss. The output of all techniques is compared to detailed measurements for validation, which led us to final conclusions.
Investigating the Conformation of HER Membrane Proteins in Cells via Single Molecule and FLIM Microscopy

Understanding how signal inputs and outputs are organised in membrane protein signalling networks is an important question in biology. The current goal is to derive methods that would allow the 'watching' of these network proteins in action and at atomic resolution to see details of their structure. This requires the addition of a 'time' dimension to structural biology so that the spatio-temporal parameters of all atoms in each protein can be described in detail. This is a huge challenge that in cell-free systems has begun to be partially addressed through dynamic experiments combined with molecular simulations. However, in cells, the functions of particular structural motifs are not just constrained by Brownian motions, energy landscapes and thermodynamics, but also by the local availability of partners in subcellular compartments and the boundary constraints imposed by cell environments, for example in the plasma membrane, with its 2D dimensionality, local curvature and electric fields. To understand protein function in cells, observations have to be made in the only physiologically-relevant 'laboratory', the cell. This adds levels of complexity to an already vast challenge.
Developing Urban Waste Disposal System: The Role of Stakeholders A Case Study of Stakeholder Values in the area of Waste Management in Gothenburg

Understanding customer demand is seen as advantageous in the hypercompetitive environment that prevails on the market today, with greater amounts of businesses operating globally. It is therefore crucial to succeed through small means, and the investigation of stakeholder values is an important matter today in order to persuade customers by offering products or services where value exceeds price. Developing sustainable solutions for waste management and disposal system is a challenge for cities, which affects many people daily; however, various actors may have a different understanding and value solutions differently. This study is made in collaboration with Envac Scandinavia AB, which offers waste disposal systems. The study examines the value perspectives from the users, developers, construction companies, and authorities point of view regarding waste disposal systems. Implications for theory and practice are further offered and a value proposition is made to Envac’s customers based on the results given from interviews.
