Time Development of Voltage Frequency Dependence of Partial Discharge Activity in Voids

Condition assessment of high voltage equipment based on partial discharge measurements is often performed after a voltage pre-conditioning period. The aim of this paper is to present results from experimental examinations of time variance of partial discharge activity and to propose physical explanations of the phenomena observed. Experiments were performed on laboratory made 3 mm thick discs of generator bar insulation, consisting of mica and glass fiber reinforced epoxy with a 0.5 mm thick cylindrical void surfaces of 10 mm in diameter. The effect of conducting and insulating void surfaces was examined using copper tape as upper and lower electrodes of the voids. All objects were tested by 12 one-minute long AC voltage frequency sweeps at frequencies from 50 Hz to 0.1 Hz distributed in time from start of the experiment, after initial one-hour constant 50 Hz voltage application and during object short-circuiting for 20 h. The main result shows that in case of insulating voids the apparent charges vanished after the one-hour constant 50 Hz voltage application. After a grounding period of 5 minutes, the charge magnitudes slowly increased with time until reaching steady state after about 4-8 hours. Test objects with conductive void surfaces showed such reduction in case of PD testing at 0.1 Hz only. At voltage frequencies above 10 Hz the measured PD magnitudes were found to be nearly constant, close to the expected high theoretical value. This indicate that PD by-products strongly affected the void resistivity and thereby affect the PD activity of insulating voids. These by-products are temporary and disappear with time.

Mathematical Modelling Time Dependent for Heat Transfer Process in Homogenous Composite ZnO/Activated CNF

A theoretical study of heat transfer on composite Zinc Oxide (ZnO)/Activated Carbon Nanofibers (CNF) by using mathematical model from diffusion equation for stationary composite with various heating time was studied. The equation and boundary conditions are interpreted by using Taylor series expansion to obtain a steady-state numerical solution from the Jacobi iteration algorithm. The composites where put inside the furnace model by filaments on the two sides of the walls as the source of heat (general model for furnace). By using this model, the position of sample to receive the homogeneous temperature determined. We compared the steady-state and unsteady-state conditions to identify the temperature distribution at real-time. The results show that the heat distribution will reach an asymptotic state by performing a numerical analysis is 200 K and 300 K for 25 minute time of heating. In this study, shows the efficient way for annealing homogenous materials to identify the position inside the furnace which can be used as a guide to receive the homogenous temperature during the annealing processes.

Frequency, Temporal Onset of Occurrence and Risk Factor Identification for Acquired Long QT Syndrome in a Critical Care Population

Background: Acquired long QT syndrome (aLQTS) is a reversible condition characterized by a pathological prolongation of the QT interval that can lead to a polymorphic ventricular tachycardia known as Torsades de Pointe and sudden cardiac death. Identifying the incidence, onset, and risk factors for aLQTS in intensive care init (ICU) populations has not been studied and may help clinicians develop safe monitoring guidelines to identify patients early preventing devastating outcomes. Objective: The objective of this study was to determine the frequency, temporal onset of occurrence, frequency of medications and host risk factors for aLQTS in an ICU. Method: In a retrospective chart review of 88 subjects, hourly electrocardiographic data collected in an ICU were analyzed for baseline, first long, longest, and final corrected QT intervals (QTc) using Bazett’s formula. aLQTS was defined as a QTc interval ≥ 500 milliseconds (ms) or a change in QTc of ≥ 60 ms from baseline. Host risk factors were collected from the physician’s dictated history and physicals and nursing admission databases. Names and timing of each medication administered were collected from the medication record. Results: aLQTS occurred in 52.3% of the ICU sample. All subjects positive for aLQTS (n=46) had a mean onset of 7.4 + 9.4 hours from ICU admission. Subjects who developed aLQTS after ICU admission (n=32) had a mean onset of

Optical Imaging of Brain Motor Cortex Activation During Wrist Movement Using Functional Near-Infrared Spectroscopy (fNIRS)

Background: Optical imaging has attracted the researcher’s attention in recent years as an uncompromising and efficient method to measure the changes in brain cortex activity. Functional Near-Infrared Spectroscopy (fNIRS) is a method that measures hemodynamic changes in the brain cerebral cortex based on optical principles. Objectives: The current study aimed to evaluate the activities of the brain cortex during wrist movement using fNIRS. Methods: In this study, the activity of the brain motor cortex was investigated during right wrist movement in 10 young right-handed volunteers. Data were collected using a 48-channel fNIRS device with two wavelengths of 855 nm and 765 nm. For this experiment, 20 channels were used and the sampling frequency was set at 10 Hz. Results: Signal intensity in the motor cortex was significantly higher during movement than in the rest (P ≤ 0.05). The activation map of wrist movements was separated spatially in the motor cortex. The highest activity was recorded in the primary motor cortex (M1). There was a significant difference in the focus of the maximum activation of the brain between the four main directions. Conclusions: It is possible to differentiate between different directions of movement using near-infrared signals. The presence of directional activation in the cerebral cortex helps confirm the notion that this part of the brain participates in the processing of complex information besides controlling the movement of different parts of the body.

A new tool for measuring and understanding individual differences in the component processes of reading comprehension

We propose a new measure of individual differences in reading comprehension ability that is theoretically motivated, is easy to administer, and that has high predictive power. Participants read 3-sentence paragraphs that describe the relations among a set of real and artificial terms, and then they respond to true-false statements that assess their ability to access and integrate long-term memory knowledge with text information, to make text-based inferences, and to recall text. The components of our task predict performance on a test of global reading comprehension and on a range of specific comprehension tests, each of which draws more heavily on one particular component. Our task is better at predicting reading comprehension than is a typical working memory span task and has the potential for advancing researchers' understanding and measurement of a range of linguistic and cognitive tasks.
Influence of degree of crystallinity on DC-conduction of polypropylene

Aim of this work was to study how degree of crystallinity influences the DC conduction characteristics of capacitor grade polypropylene (PP). PP pellets were pressed to 0.3 mm plates using two different cooling rates in order to vary the degree of crystallinity. The DC conduction currents were measured at 50 and 70 °C at 8-55 kV/mm. 3 h polarization and 15 h depolarization times were used. It turned out that temperature and the dielectric stress played a more dominant role regarding DC-conductivity than the obtained ~4 wt-% difference in crystallinity. Especially at 39-55 kV/mm, when temperature increased from 50 to 70 °C the DC-conductivity increased 10-15 times. There was however a trend related to the degree of crystallinity: the increase in crystallinity (more slowly sample cooling) led to lower conductivity values.
THE COMPONENTS OF NONVERBAL COMMUNICATION IMPORTANT FACTORS IN THE TEACHING PROCESS

The act of teaching is a predominantly verbal. Nevertheless communication during the teaching process equally depends on the paraverbal and nonverbal components, that are meant to reinforce the formative interaction between the teacher, as traditional transmitter, and the student as receiver of information. Given the importance of nonverbal communication in career and life, the authors of the paper, aware of the fact that the issue is not part of all school syllabi, made a study on two groups of students in order to test their knowlege on the topic as well as to find out their reactions towards the professorssâ€™ sundry nonverbal means of communication.
Interfacial Tension Prediction of Readily-Mixed Waxy Crude Oil Emulsion at Pour Point Temperature

In the industry, stubborn emulsion still constitutes up to 20% of the total emulsion volume. The existing remediation strategies for emulsion treatment rely heavily on the study of heavy crude oil emulsion. However, minimal information is available on integrating interfacial rheology with emulsion stability on waxy crude oil emulsion. The proposed research provides a study to the development of integration between interfacial rheology and emulsion stability so that it can be a quick assessment but an accurate method to measure emulsion stability. The primary objectives of the research are to provide an extensional study to the design development of a comprehensive interfacial rheology protocol for the assessment of emulsion stability by developing a method of testing and monitoring the interfacial rheology and to investigate the demulsification ability of the waxy crude oil emulsion subjected to microbial treatment. The novelty of this study is to use the newly developed measurement protocol via interfacial rheology to predict emulsion stability. Application of the microbes on waxy crude oil to breakdown the water-in-oil emulsion using a rheometer will also be explored. The treatment is targeted to disintegrate the interfacial layer within the emulsion leading to better oil recovery. Rheological properties of the emulsion will be monitored upon the microbial injection to analyze the effects of the treatment on the rheology of emulsion. The outcomes from this research is that the newly developed protocol will predict emulsion stability that could resolve the stubborn emulsion issues via the developed interfacial rheology protocol, which could be time-saving and increases the production efficiency. This research paper is a study to develop a correlation on surface tension and interfacial tension between crude oil, water and a readily-mixed emulsion.
Fabrication of aligned nanofiber yarns, mats and isolation of single nanofiber in electrospinning

FABRICATION OF ALIGNED NANOFIBER YARNS, MATS AND ISOLATION OF SINGLE NANOFIBER IN ELECTROSPINNING by Venkatesh T. Nathilvar Electrospinning has been extensively used as an effective technique for the fabrication of submicron and nanometer scale polymeric fibers. In spite of technological advances in electrospinning, creating a highly aligned fiber structure is a tough target to be achieved because of the chaotic motion of the electrospinning jet. In this study, two different techniques have been adopted to form a highly aligned nanofibrous scaffolds. Using these methods highly aligned fiber yarns and mats are produced from Cellulose Acetate (CA) in a mixed solvent of acetone and water. In both the techniques the nanofibers suspend over the gap in a highly oriented manner, and they can be easily transferred onto a substrate for further applications. Since the fibers generated by electrospinning are in micrometer and nanometer scale, it is very complex to isolate and manipulate an individual nanofiber. To address this issue, the technique that is used to fabricate nanofiber mat is incorporated with some modifications to isolate a single nanofiber.

Size, Composition, and Support-Doping Effects on Oxygen Reduction Activity of Platinum-Alloy and on Non-platinum Metal-Decorated-Graphene Nanocatalysts

Recent investigations reported in the open literature concerning the functionalization of graphene as a support material for transition metal nanoparticle catalysts have examined isolated systems for their potential Oxygen Reduction Reaction (ORR) activity. In this work we present results which characterize the ability to use functionalized graphene (via dopants B, N) to upshift and downshift the adsorption energy of mono-atomic oxygen, O* (the ORR activity descriptor on ORR Volcano Plots), for various compositions of 4-atom, 7-atom, and 19-atom sub-nanometer binary alloy/intermetallic transition metal nanoparticle catalysts on graphene (TMNP-MDG). Our results show several important and interesting features: (1) that the combination of geometric and electronic effects makes development of simple linear mixing rules for size/composition difficult; (2) that the transition from 4- to 7- to 19-atom TMNP on MDG has pronounced effects on ORR activity for all compositions; (3) that the use of B and N as dopants to modulate the graphene-TMNP electronic structure interaction can cause shifts in the oxygen adsorption energy of 0.5 eV or more; (4) that it might be possible to make specific doped-graphene-NixCuy TMNP systems which fall close to the Volcano Peak for ORR. Our results point to systems which should be investigated experimentally and may improve the viability of future fuel cell or other ORR applications, and provide new paths for future investigations of more detail for TMNP-MDG screening.
Commissioners' Attendance at Board Meeting: An Empirical Analysis of Indonesian State-Owned Enterprises

Indonesia applies two-tier system of board in which board is divided into supervising board (or board of commissioners) and executive board (or board of directors). In the context of Indonesian state-owned enterprises (SOE), there have been popular claims that commissioners are not serious enough in holding their seats due to their busyness or incapability to handle the jobs. This is eventually due to massive political intervention during the selection and appointment of commissioners of Indonesian SOE.This research aims to empirically test the popular claims. Using busyness hypothesis developed by Ferris et al. (2003), I argue that attendance rate of Board of Commissioners (BoC) at board meeting (both internal meeting and joint meeting) is lower than that of Board of Directors (BoD). I then analyze the explaining factors of BoC attendance rate, both at board-level and individual level.The empirical results show that BoC attendance rate at both board meeting is significantly lower than that of BoD. But only board size and age consistently have significant coefficient on regression analysis at board-level and individual level analysis.I conclude that the popular claims of Indonesian SOE BoC ineffectivess cannot be fully supported.

Transient energy growth of channel flow with cross-flow

The effect of a uniform cross flow (injection/ suction) on the transient energy growth of a plane Poiseuille flow is investigated. Non-modal linear stability analysis is carried out to determine the two-dimensional optimal perturbations for maximum growth. The linearized Navier-Stockes equations are reduced to a modified Orr Sommerfeld equation that is solved numerically using a Chebychev collocation spectral method. Our study is focused on the response to external excitations and initial conditions by examining the energy growth functionG(t)and the pseudo-spectrum. Results show that, the transient energy of the optimal perturbation grows rapidly at short times and decline slowly at long times when the cross-flow rate is low or strong. In addition, the maximum energy growth is very pronounced in low injection rate than that of the strong one. For the intermediate cross-flow rate, the transient energy growth of the perturbation, is only possible at the long times with a very high-energy gain. Analysis of the pseudo-spectrum show that the non-normal character of the modified Orr-Sommerfeld operator tends to a high sensitivity of pseudo-spectra structures.
THE PREDICTORS OF SPORTS TOURISM INVOLVEMENT IN MALAYSIA: AN EXTREME SPORT OVERVIEW

Purpose of Study: Malaysian tourism sector has widened its scope by venturing into extreme sports tourism. With this new development, tourism opportunities are created and boosting the Malaysian tourism industry growth. The study highlights the development of extreme sports destination that closely related to international and tourists’ involvement and preferences in Malaysia. The purpose of this paper is to determine the predictors of sports tourism involvement in Malaysia from the extreme sports perspective. Specifically, it is going to investigate the possible significant predictors that possibly influenced the international or local tourists’ preferences in choosing Malaysia as their preferred extreme sports tourism destination. This study is restricted to international or local tourists who participated or going to participate in extreme sports activities in Malaysia. Methodology: This study proposes a theoretical framework that is developed based on the review of past researches and literatures. We identified five factors that possibly influenced international tourists or local tourists to choose Malaysia as their extreme sports tourism destination simultaneously involved in such activities. Those predictors are event popularity and entertainment, economics (costs and expenses), facilities and infrastructures, social, and environmental impact. Results: The proposed hypotheses predicted a significant and positive relationship exists between event popularity and entertainment, economics (costs and expenses), facilities and infrastructures, social, and environmental impact towards the tourist involvement and sports tourism development in Malaysia. For the future research, we proposed to further conduct an empirical analysis to test these hypotheses. Implications/Applications: This study could help tourism sectors to explore opportunities for development particularly in the extreme sports sectors in Malaysia. This study is also useful for researchers, students, tourism operators, tourism sectors, government and society because it could increase the involvement of international tourist or local into the extreme sports activities in Malaysia.
