The Influence of Thermal Radiation on Mixed Convection MHD Flow of a Casson Nanofluid over an Exponentially Stretching Sheet

The present article describes the effects of thermal radiation and heat source/sink parameters on the mixed convective magnetohydrodynamic flow of a Casson nanofluid with zero normal flux of nanoparticles over an exponentially stretching sheet along with convective boundary condition. The governing nonlinear system of partial differential equations along with boundary conditions for this fluid flow converted to a system of nonlinear ordinary differential equations by using appropriate similarity transformations. The converted system of equations were solved numerically by using Runge-Kutta fourth order method with shooting technique. The influence of various non-dimensional governing parameters on velocity, temperature and nanoparticle volume fraction profiles have been discussed and presented graphically. Furthermore, the impacts of these parameters on skin friction coefficient and local Nusselt number are exhibited graphically and analized. It found that the velocity profiles and skin friction coefficient increases with an increase in the mixed convection parameter whereas, an opposite trend observed with Casson fluid parameter and magnetic field parameter. The thermal boundary layer thickness enhanced with an increase in Biot number, magnetic field parameter, radiation parameter and heat source/sink parameter. Also, the local Nusselt number decreases with an increase in radiation parameter and heat source/sink parameter.
Compulsory for Whom? Mandatory Voting and Electoral Participation in Brazil, 1986-2006

Latin America contains roughly half of the world's countries that use compulsory voting, but this electoral institution has received only limited attention from researchers. This article examines the determinants of voter turnout in the world's largest electorate subject to mandatory voting, that of Brazil. In analyzing data from six national legislative elections held in Brazil between 1986 and 2006, the study finds that the impact of compulsory laws varies across social and economic groups. From a methodological perspective, the article argues that “compulsoriness” of mandatory voting legislation can be modeled by taking into account both exemptions to the law and the relevance of potential sanctions against non-voters. The issue of enforcement must be considered if we are to develop comprehensive models of electoral participation under conditions of compulsory voting.
FEL POTENTIAL OF THE HIGH CURRENT ERLS AT BNL

An ampere class 20 MeV superconducting Energy Recovery Linac (ERL) is under construction at Brookhaven National Laboratory (BNL) for testing concepts for high-energy electron cooling and electron-ion colliders. This ERL prototype will be used as a test bed to study issues relevant for very high current ERLs. High average current and high performance of electron beam with some additional components make this ERL an excellent driver for high power far infrared Free Electron Laser (FEL). A possibility for future up-grade to a two-pass ERL is considered. We present the status and our plans for construction and commissioning of the ERL. We discus a FEL potential based on electron beam provided by BNL ERL.
Storing and analysing massive aerial LiDAR datasets in a DBMS

While a DBMS is usually the tool of choice to handle massive amount of data, its use for LiDAR datasets is somewhat problematic. Indeed, storing millions—or even billions—of unconnected points is feasible but to be able to analyse and manipulate them more is needed: we must reconstruct the surface represented by the sample points, and we must also be able to efficiently access this surface and derive values from it.
Research on Methods of Microblogging Sentiment Feature Extraction Based on Dependency Parsing

Microblogging emotional elements extraction recall rate is extremely low without opinion words expansion. Aiming at the feature extraction of Microblogging sentiment, a sentiment feature extraction method based on dependency parsing for the Microblogging emotional has been proposed in this paper, abbreviated as MSFE_DP. The specific steps are as follows: First, the existing opinion words were expanded to build a special emotional thesaurus. Second, according to the six dependencies modes of emotional words and evaluation objects, evaluation units were identified and extracted automatically. Finally, a complete evaluation object was obtained in combination with the evaluation object merging algorithm. Through participating in NLP&CC Chinese Microblogging emotional public evaluation, MSFE_DP took the third place among the 22 approaches in the evaluation tasks, which indicates that our method is effective.
Temperature prediction analysis considering an optimal distribution of stations: clusters or randomly

Global mean surface air temperature is the most used measure of the climate system. Nowadays, due to the climate change problem, the interest of predicting climatic values in areas without stations has increased a lot and has been developed new interpolation methods. If we associate temperature stations with their spatial coordinates, along with other variables, it is possible to identify them by means of a spatio-temporal stochastic process. Two are the objectives in this work. Firstly, to predict the mean temperature throughout Catalonia taking into account the total number of stations (180). Secondly, to analyse the goodness of prediction reducing the number of stations gradually. At first, we consider less randomly chosen stations (160, 100, 80) and then we select stations, which are in clusters. We specified spatial log-Gaussian process models. Models are estimated using Bayesian inference for Gaussian Markov Random Field (GMRF) through the Integrated Nested Laplace Approximation (INLA) algorithm. The results allow us to quantify the minimum number of stations which are needed to do the best prediction of the mean temperature in Catalonia as well as to know the best distribution of these stations. We believe the methods shown in this study may contribute to improve prediction studies and to reduce computational cost of these predictions.
The notion of lifeworld applied to information systems research

The paper revisits the notion of emancipation in Information System Development (ISD) that seems to have lost a battle against functionalist and managerialist approaches dominant in information system (IS) research and practice. Unlike functionalist and managerialist views, the emancipatory view of ISD, informed by Critical Theory, considers ISD as a site of organizational innovation, self-reflection and a struggle for humanization of work and liberation from different forms of domination. Critics of emancipatory project in IS and management literature question the very possibility of the emancipation and deplore its intellectualism, naivety and negativism. The purpose of this paper is to re-consider the notion of emancipatory ISD in the face of these criticisms and develop a more refined and nuanced view of micro-emancipation in ISD that is meaningful in practice. Informed by Alvesson and Willmott (1992, 1996) we explore, question, redefine and ground the micro-emancipatory ISD processes based on a longitudinal (15 year) study of a retail company. Our analysis and critical reflection demonstrate that micro-emancipatory ISD processes have real substance for the people involved, and that their meanings are neither fixed nor universal, but rather local, emergent, uncertain, and sometimes contradictory. This paper contributes an empirically grounded and practically relevant reconceptualization of micro-emancipatory ISD projects which reveals both its benefits and risks for all involved.
Critical Data Delivery Using TOPSIS in Wireless Body Area Networks

Technology development in the Wireless Sensor Network (WSN) has paved the way for body area network for remote health monitoring. For this purpose, a message or a data packet should be transmitted from the patient to the medical evaluator without any loss. In this work, Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) algorithm is implemented for Wireless Body Area Networks (WBAN) to deliver the message, based on the criticality of the pa- tient. Finally, we compare the results for both the real-time data and the simulated (random) values in terms of packet-size forwarding for different parameters such as Packet Delivery Ratio (PDR), Delay and Throughput. The result shows better performance in the real time value by using TOPSIS scheme in the WBAN. By improving the quality of service in body area networks, health monitoring system can be automated with good performance.
Fixed-Rank Representation for Image Classification Using ANN and KNN

This study is focused on development an application of an efficient algorithm for subspace clustering and feature extraction that used for classification. Some previous techniques for subspace clustering make use of rank minimization and sparse based such as SSC and LRR are computationally expensive and may degrade clustering performance. So the need is to solve the problems of existing techniques, an algorithm is introduced known as Fixed-Rank Representation i.e. FRR based on matrix factorization is used for subspace clustering and feature extraction and that features are used for classification. For classification we use k-nearest neighbour and neural network classifiers and compare their accuracy or performance to classify the feature extracted from FRR.
Growth Aspects and Biochemical Composition of Synechococcus sp. MK568070 Cultured in Oil Refinery Wastewater

The aim of the study was to explore the possibility of bioremediation of oil refinery wastewaters by the cyanobacterium Synechococcus sp. MK568070, isolated from the Adriatic Sea. The potential of biomass and lipid production was explored upon cultivation on oil refinery wastewater with excess CO2 after the removal of nutrients. The strain grew well in a wide range of salinities and ammonium concentrations, and was further tested on the wastewater from local oil refinery plant of various N-composition. Growth experiment under optimized conditions was used to analyze the lipid, carbohydrate and protein dynamics. The biomass yield was highly dependent on nutrient source and concentration, salinity and CO2 addition. Highest biomass yield was 767 mg/L of dry weight. Towards the end of the experiment the decline in carbohydrate to 18.9% is visible, whereas at the same point lipids, in particular saturated fatty acid methyl esters (FAME), started to accumulate within the cells. The content of lipids at the end of the experiment was 21.4%, with the unsaturation index 0.45 providing good biofuel feedstock characteristics. Fourier Transform Infrared (FTIR) spectroscopy analysis demonstrated a high degree of lipid accumulation in respect to proteins, along with the structural changes and biomass accumulation. In addition, the N-removal from the wastewater was >99% efficient. The potential of lipid accumulation, due to the functional photosynthesis even at the minimal cell quota of nutrients, is critical for the usage of excess industrial CO2 and its industrial transformation to biodiesel. These findings enable further considerations of Synechococcus sp. (MK568070) for the industrial scale biomass production and wastewater remediation.
Mediating tourism : an analysis of the image of the Caribbean in the UK national press

Studies on tourism destination images have traditionally been based on the measurement of consumers' cognitive images of destinations. Few have examined the images of destinations conveyed by media texts to determine how they are likely to influence consumer perceptions. Therefore the purpose of the study is to identify and to analyse mediated image constructs of Caribbean destinations and their holiday experiences in order to clarify their relationship to consumer responses. In pursuing this goal, this thesis examines how these images have been constructed in newspaper narratives to determine the meanings of these constructs and to interrogate the representational practices of the UK press of Caribbean destinations. A tripartite schema of landscape, local people and activities was identified as the main classification of mediated tourism destination images (TDI) and this framework was used to conduct content and discourse analyses of newspaper stories published on these destinations in the Sunday editions of the UK national newspapers in 2000. The findings of this study show a pattern of image constructs that featured the dominance of landscape attributes and recreational modes of seeing and experiencing Caribbean destinations. The prevalence and dominance of these stereotypes were demonstrated by the similarity of image constructs of the destinations across the various segments of the UK national newspapers. It was found that the shared news values and culture of the UK media reflect dominant epistemologies of Caribbean destinations in terms of the 'Other'. However, it was argued that these stereotypical images lack symbolic resonance and appeal and as such may be reducing brand identity and competitiveness of these destinations as well as devaluing the Caribbean holiday experience. In proposing a tourism destination image media matrix as a heuristic model that links functional and enactive imagery to low elaboration/involvement responses and affective and holistic imagery to high elaboration/involvement, this study presents clarification on the role of mediated images as key determinants of consumer perceptions and responses.
"We Considered Ourselves a Team": Co-Teaching from the Perspective of Graduate Teaching Assistants

Previous research has explored the influence of co-teaching models on student learning in the K-12 grade curriculum. However, little research explores the effects of co-teaching models implemented in higher education among graduate teaching assistants (GTAs). This case study examines the benefits and drawbacks of co-teaching models in higher education classes for GTAs. Two sections of the basic communication course (one for international students and one for American students) at a mid-sized Midwestern university were combined for 50% of the semester classes. Lessons with a focus on intercultural communication were co-constructed and co-taught by two GTAs. Based on this experience, a reflexive journal was used to identify emerging themes pertaining to the benefits, drawbacks, and student learning outcomes of co-teaching by GTAs in higher education. In addition, in-depth semi-structured interviews were used to gather the perspectives of three GTAs with co-teaching experience. Results reveal variety of teaching approaches, wealth of instructor experiences, instructor chemistry, and instructor approachability as benefits of co-teaching. Perceived drawbacks include power distances and lack of familiarity with pedagogy and co-teaching models. Implications for GTAs and students in higher education are explored.
Invertebrate palaeontology and sequence stratigraphy: complementary methods and evidence to explain the geological record

The fossil record and the stratigraphic record are two components of the geological record different in nature, and they can be separately interpreted and tested in many cases of Invertebrate Palaeontology. Abundance, diversity and stratigraphic persistence are outstanding features of the fossil invertebrates. Therefore, the complementarity (as the capacity of two contrasted theories together to explain a body of phenomena, although each separately accounts for only some aspects) or the consilience (as the fact or condition of being inferred from different phenomena) between Palaeontology and Sequence Stratigraphy through the study of fossil invertebrates is specially useful for the interpretation of the geological record and the palaeoenvironmental changes.
Determination of imatinib mesylate and erlotinib hydrochloride in mice plasma using ultrahigh performance liquid chromatography method

This study aimed to develop a rapid, user-friendly, economic and sensitive method for analyzing imatinib mesylate (IMA) and erlotinib hydrocloride (ERLO) in mice plasma using ultrahigh performance liquid chromatography (UPLC). Separation was achieved by isocratic elution using a mobile phase consisting of the mixture of 3mM triethylamine and acetonitrile with the ratio of 60:40 using XTerra® RP8 column (5 μm 4.6x150 mm). The retention time for IMA was 4.9 minutes with a flow rate of 1.5mL/min, while the retention time for ERLO was 5.0 minutes with a flow rate of 0.8mL/min. Injection volume was set to 20μL and the detector wavelength was 320 nm. Detection limits for imatinib mesylate and erlotinib hydrochloride were 95 and 72 ng/mL, respectively. This method was validated in terms of linearity, selectivity, recovery, precision and accuracy. This simple and sensitive method can be successfully used in research and easily adapted for analyses of other types of tyrosine kinases receptor inhibitors.
The Effect of Perceived Organizational Support and Job Satisfaction

Construction industries are exposed to a high competition. Such situation could affect the emloyees since organization also increase their demand in terms of long working hours, high workload, high quality standard, and lack of job security. Facing this challenges some employees might feel less satisfied and tend to come out with quick response to leave the organization. This paper aims to explore the turnover intention in constrcution industry. A questionnaire is used to collect data from 110 employees. The results reveal that most respondents perceived good support from organization and fel satisfy. While they have low intention to leave. The perceived organizational support positively affect turnover intention and job satisfaction mediated the relation. This study using small sample size which means any generalisations should be done carefully. Meanwhile, the cross-sectional approach only highlight the existence of relationships between variables but it didnot discuss their exact nature. Keywords—perceived organization support; job satisfaction; turnover intention
Effect of microwave and solar drying methods on the physico- chemical properties of kiwifruit

Drying kiwifruits by open-air sun drying (OASD) with three samples thickness (4mm; 8mm; 10mm) and microwave drying (MW) with three output powers density (1w/g; 1.5w/g; 2w/g) has been proceeded. The effects of the different drying methods on the physicochemical properties (moisture, pH, °Brix, total phenolics, total flavonoids, and carotenoids contents) were assessed. Both drying methods caused decline in Brix and moisture. However, drying kiwifruit by microwave was faster than using OASD method. Whereas fruit pH was decreasing by MW treatments, it was conversely increased by OASD. The highest gain in total phenolics (TP), total flavonoids (TF) and total carotenoids (TC) contents was recorded in kiwifruit dried by OASD method.
Toward autonomous surface-based infrared remote sensing of polar clouds: cloud-height retrievals

Abstract. Polar regions are characterized by their remoteness, making measurements challenging, but an improved knowledge of clouds and radiation is necessary to understand polar climate change. Infrared radiance spectrometers can operate continuously from the surface and have low power requirements relative to active sensors. Here we explore the feasibility of retrieving cloud height with an infrared spectrometer that would be designed for use in remote polar locations. Using a wide variety of simulated spectra of mixed-phase polar clouds at varying instrument resolutions, retrieval accuracy is explored using the CO2 slicing/sorting and the minimum local emissivity variance (MLEV) methods. In the absence of imposed errors and for clouds with optical depths greater than ∼ 0.3, cloud-height retrievals from simulated spectra using CO2 slicing/sorting and MLEV are found to have roughly equivalent high accuracies: at an instrument resolution of 0.5 cm−1, mean biases are found to be ∼ 0.2 km for clouds with bases below 2 and −0.2 km for higher clouds. Accuracy is found to decrease with coarsening resolution and become worse overall for MLEV than for CO2 slicing/sorting; however, the two methods have differing sensitivity to different sources of error, suggesting an approach that combines them. For expected errors in the atmospheric state as well as both instrument noise and bias of 0.2 mW/(m2 sr cm−1), at a resolution of 4 cm−1, average retrieval errors are found to be less than ∼ 0.5 km for cloud bases within 1 km of the surface, increasing to ∼ 1.5 km at 4 km. This sensitivity indicates that a portable, surface-based infrared radiance spectrometer could provide an important complement in remote locations to satellite-based measurements, for which retrievals of low-level cloud are challenging.

Quantitative Analysis of Force and Torque in Bone Drilling

Bone drilling is an important and the most frequent operation in orthopaedics and other bone surgical procedures. Prediction and control of drilling force and torque are critical to safe and efficient surgeries. This paper studies the drilling force and torque arising from bone drilling process. Drilling parameters such as drilling speed, feed rate, drill size and drill condition (sharp and worn) were changed to measure the force and torque in the direction of the drill penetration. Experimental results demonstrated lower drilling force using a sharp drill compared to a worn drill for similar drilling conditions. Contrary to the drilling force, lower torque was measured using a worn drill compared to a sharp drill. The drilling force was found to decrease with increase in drill speed and increased with rise in the feed rate using both types of drills. A linear drop in drilling torque was measured with increase in drilling speed. This study provided scientific information to orthopaedic surgeons and technicians to use appropriate surgical drill and cutting parameters to avoid overstressing of the bone tissue and drill breakage during drilling operations.
