Numerical study on sticking of paper in electrostatic transfer process for electrophotography

A numerical study was carried out on the electrostatic sticking of a charged paper to photoreceptor in electrostatic transfer process for electrophotography. Numerical procedures to predict sticking of the paper were presented which consists of (1) determination of initial angle of the paper, (2) estimation of electric field intensity, (3) estimation of charge on paper created by Paschen's air breakdown, (4) estimation of electrostatic force acting on the paper and (5) calculation of deformation of paper. Deformation of the charged paper in electric field was numerically simulated according to the procedures and the dependencies of paper sticking on photoreceptor size and initial angle of paper were quantitatively clarified. It is clarified that the smaller and softer photoreceptor improves sticking of paper.
Millimeter-wave semiconductor two-port network at 77K

The gyromagnetic properties of magnetized ferrites are widely used in many novel rf and microwave devices. According to the Drude model, similar principles should also be applicable to magnetized semiconductors due to its gyroelectric properties. In this study, an axially magnetized semiconductor resonator is characterized in terms of bias field and signal frequency. The resonance and loss regions are identified at 77 K. The affect of changing material and geometrical properties of the resonator on the splitting and tuning behavior of normal modes are illustrated. Green's Function approach is used to derive the S-parameters of a two port semiconductor network. The network response and the material properties can be used to calibrate the semiconductor material before measuring the millimeter-wave properties of the resonator. This theoretical analysis may prove to be vital in realizing miniaturized and broadband semiconductor junction circulators and filters for high- Tc superconductive circuits.

Sustainable Marketing Strategies for the Micro, Medium and Small Scale Industries of West Bengal - An Empirical Study on Bamboo Artifacts

West Bengal has a well-defined plan for advancement of Micro, Small and Medium Scale Industry sector through the active support of West Bengal Small Industries Development Corporation and other agencies under the MSME Department. Various districts and regions of West Bengal are famous for its MSMEs. Craftsmen/SHGs of Purulia create a myriad of utilitarian items made from bamboo. Yet, with the liberalization of market economy, bamboo artifact of West Bengal is lagging behind with the modern market system in terms of quality of product, quality of skill, access to market, marketing plan, distribution channel, packaging, etc. It is the fact that the manufacturers of this art and craft need infrastructure development, creation of industrial estates, marketing support, skill up gradation, smooth distribution channel, skill of packaging, etc. To bridge these gaps, a market survey was conducted at West Bengal to understand the demand for bamboo artifacts in the local and wider markets and also to formulate a sustainable business strategy for marketing the product and services. The prime objectives of the study were to reveal the gaps at present context. Finally the study aims to develop a broad strategy framework for sustainable livelihood development around bamboo. Detailed interviews through a structured questionnaire were conducted with the various stakeholders in Purulia to assess their viewpoints with respect to the market potential and gaps.

Nuclear electric propulsion: An integral part of NASA's nuclear propulsion project

An experimental investigation was conducted to determine the effect of nozzle area ratio on the operating characteristics and performance of a low power dc arcjet thruster. Conical thoriated tungsten nozzle inserts were tested in a modular laboratory arcjet thruster run on hydrogen/nitrogen mixtures simulating the decomposition products of hydrazine. The converging and diverging sides of the inserts had half angles of 30 and 20 degrees, respectively, similar to a flight type unit currently under development. The length of the diverging side was varied to change the area ratio. The nozzle inserts were run over a wide range of specific power. Current, voltage, mass flow rate, and thrust were monitored to provide accurate comparisons between tests. While small differences in performance were observed between the two nozzle inserts, it was determined that for each nozzle insert, arcjet performance improved with increasing nozzle area ratio to the highest area ratio tested and that the losses become very pronounced for area ratios below 50. These trends are somewhat different than those obtained in previous experimental and analytical studies of low Re number nozzles. It appears that arcjet performance can be enhanced via area ratio optimization.
Creating Realistic Corpora for Forensic and Security Education

We present work on the design, implementation, distribution, and use of realistic forensic datasets to support digital forensics and security education. We describe in particular the “M57-Patents” scenario, a multi-modal corpus consisting of hard drive images, RAM images, network captures, and images from other devices typically found in forensics investigations such as USB drives and cellphones. Corpus creation has been performed as part of a scripted scenario; subsequently it is less “noisy” than real-world data but retains the complexity necessary to support a wide variety of forensic education activities. Realistic forensic corpora allow direct comparison of approaches and tools across classrooms and institutions, reduce the time required to prepare useful educational materials, and eliminate concerns of exposing students to privacy-sensitive or illegal digital materials. The “M57Patents” corpus can be freely redistributed without rights-restricted materials, and is available with disk images packaged in both open (Advanced Forensic Format) and commercial (EnCase) formats.
Genetic Variability, Correlation and Path Coefficient Analysis in Chickpea (Cicer arietinum L.) for Yield and its Component Traits

Chickpea (Cicer arietinum L.) is a selfpollinated crop, with 2n = 2x = 16 chromosomes and genome size of 732 Mb. Vavilov (1926) designated southwest Asia and the Mediterranean as primary and Ethiopia as secondary centres of diversity. India contributes major share of world’s chickpea area (70%) and production (67%) and continues to be the largest chickpea producing nation. To meet domestic demand, India also imports large quantity of desi chickpea, but in past decade, it has emerged as a major exporter of kabuli chickpea.
Vascular Access, Complications and Survival in Incident Hemodialysis Patients

The arteriovenous fistula (AVF) has long been considered the optimal vascular access. However, the evolving characteristics of the ageing dialysis population limit the creation of an AVF in all patients. Thus, more patients start hemodialysis (HD) with a central venous catheter (CVC) rather than an AVF, and the supremacy of the AVF has recently been questioned. The aim of this study was to analyze the incidence and rate of access complications in 100 patients between 2010 and 2015. A total of 63 patients started HD with an AVF, while 37 began HD with a CVC. We found no differences in patient survival according to the vascular access in use at the beginning of dialysis, but patients were more likely to die while undergoing dialysis by means of a CVC than an AVF. Patients started on dialysis with a CVC had more cardiovascular disease, while patients who began dialysis with an AVF presented more hypertension. Fistulas presented a longer survival time despite more hospital admissions, but CVCs bore a higher risk of infections. Our results suggest that starting dialysis with a CVC does not confer a greater risk of death.
Influence of Slot Number on Electromagnetic Performance of 2-pole High-Speed Permanent Magnet Motors With Toroidal Windings

This article investigates the influence of stator slot number on electromagnetic performance of two-pole high speed permanent magnet (HSPM) slotted motors with toroidal (TO) windings. Four two-pole slotted motors with different slot numbers, i.e., 3, 6, 9, and 12, are globally optimised for maximum torque, and their electromagnetic performance are compared, including winding factor, air-gap flux density, back electromotive force, cogging torque, electromagnetic torque, winding inductances, unbalanced magnetic force (UMF), and various loss components. It shows that the six-slot/two-pole HSPM motor with TO windings is eminently suitable for high speed application due to no UMF and easy to realise a modular structure. In addition, TO and tooth-coil windings are compared in the three-slot/two-pole motors, and the results confirm that TO windings are not suitable for use in the three-slot/two-pole HSPM slotted motor due to large airgap field harmonics. Finally, a six-slot/two-pole prototype motor is manufactured and tested to validate the finite element predictions.
Establishment Of Chronic Strongyloides ratti Infection Model And Its Diagnostic Significance

Infection with Strongyloides stercoralis is associated with asymptomatic chronic disease involving the gut and respiratory systems and can persist for long period undetected leading to development of fatal hyperinfection syndrome. The severity is even more in immunocompromised individuals or patients undergoing immune suppressive therapy. Unfortunately the disease is difficult to diagnose due to low parasite load and the irregular larval output. Development of efficient diagnostic techniques requires large supply of infective larvae and this can be achieved through in vivo maintenance of the
Study More Tomorrow

We design a commitment device for college students, “Study More Tomorrow,” conduct a randomized controlled trial testing a model of its takeup, and measure its effect on tutoring attendance and grades. The device commits students to attend tutoring if their midterm grade falls below a prespecified threshold. Unlike other commitment devices tested in the education literature, the contract carries a financial cost for noncompliance. Students value the contract, with 10% takeup among those randomly assigned a contract offer. Takeup is not higher among students randomly assigned to a lower contract price, however. The contract does not robustly affect tutoring attendance or student course grades. Our results show that college students are willing to pay for study commitment devices.

Identifying Myocardial Infarction Using Hierarchical Template Matching–Based Myocardial Strain: Algorithm Development and Usability Study

Background Myocardial infarction (MI; location and extent of infarction) can be determined by late enhancement cardiac magnetic resonance (CMR) imaging, which requires the injection of a potentially harmful gadolinium-based contrast agent (GBCA). Alternatively, emerging research in the area of myocardial strain has shown potential to identify MI using strain values. Objective This study aims to identify the location of MI by developing an applied algorithmic method of circumferential strain (CS) values, which are derived through a novel hierarchical template matching (HTM) method. Methods HTM-based CS H-spread from end-diastole to end-systole was used to develop an applied method. Grid-tagging magnetic resonance imaging was used to calculate strain values in the left ventricular (LV) myocardium, followed by the 16-segment American Heart Association model. The data set was used with k-fold cross-validation to estimate the percentage reduction of H-spread among infarcted and noninfarcted LV segments. A total of 43 participants (38 MI and 5 healthy) who underwent CMR imaging were retrospectively selected. Infarcted segments detected by using this method were validated by comparison with late enhancement CMR, and the diagnostic performance of the applied algorithmic method was evaluated with a receiver operating characteristic curve test. Results The H-spread of the CS was reduced in infarcted segments compared with noninfarcted segments of the LV. The reductions were 30% in basal segments, 30% in midventricular segments, and 20% in apical LV segments. The diagnostic accuracy of detection, using the reported method, was represented by area under the curve values, which were 0.85, 0.82, and 0.87 for basal, midventricular, and apical slices, respectively, demonstrating good agreement with the late-gadolinium enhancement–based detections. Conclusions The proposed applied algorithmic method has the potential to accurately identify the location of infarcted LV segments without the administration of late-gadolinium enhancement. Such an approach adds the potential to safely identify MI, potentially reduce patient scanning time, and extend the utility of CMR in patients who are contraindicated for the use of GBCA.
Predictive toxicogenomics for the identification of chemical carcinogens : application to human hepatic cell lines

Direct comparison of the hepatoma cell lines HepG2 and HepaRG has previously been performed by only evaluating a limited set of genes or proteins. In this study, we examined the whole-genome gene expression of both cell lines before and after exposure to the genotoxic (GTX) carcinogens aflatoxin B1 and benzo[a]pyrene and the nongenotoxic (NGTX) carcinogens cyclosporin A, 17-beta Estradiol, and 2,3,7,8-tetrachlorodibenzo-para-dioxin for 12h and 48h. Before exposure, this analysis revealed an extensive network of genes and pathways, which were regulated differentially for each cell line. The comparison of the basal gene expression between HepG2, HepaRG, primary human hepatocytes (PHH) and liver clearly showed that HepaRG resembles PHH and liver the most. After exposure to the GTX and NGTX carcinogens, for both cell lines, common pathways were found that are important in carcinogenesis, for example, cell cycle regulation and apoptosis. However, also clear differences between exposed HepG2 and HepaRG were observed and these are related to common metabolic processes, immune response and transcription processes. Furthermore, HepG2 performs better in discriminating between GTX and NGTX carcinogens. In conclusion, these results have shown that HepaRG is a more suited in vitro liver model for biological interpretations of the effects of exposure to chemicals, whereas HepG2 is a more promising in vitro liver model for classification studies using the toxicogenomics approach. Although, it should be noted that only five carcinogens were used in this study. 32 Chapter 2
The Application of Computer-Aided Assessment to Postgraduate Study in Sports Management

Computer-aided/assisted assessment (CAA), or Computer-based assessment (CBA) has been developed since the mass-expansion of the personal computer in the late 1980’s and early 1990’s. A body of literature which reflects the relatively new nature of the field has been developed on the subject - Bull and Danson (2004) offer a comprehensive listing - although the common view is that CAA is ‘the use of computers to deliver, mark and analyse assignments or examinations’ (Bull and McKenna 2004). Other authors have investigated the use of CAA as a stand-alone assessment tool used in conjunction with class-based teaching or as a tool that is embedded within a virtual learning environment (VLE). This article does not intend to represent a typology of CAA forms, or a literature review of its benefits, disadvantages or uses but will focus, instead, on theoretical and operational aspects of formative assessment within a specific framework – the kind of learning situation that arises in a class-based environment, accompanied by an on-line teaching environment such as WebCT. That is the current situation within the Department of Business and Service Sector Management at LondonMet and here, the application of CAA to formative assessment will be investigated in the light of the sport management subject area specifically focusing on the MA Sport Management (MASM). The context is the Business and Service Sector Management subject area which is very broad with about 4000 students. The total Sport Management student body is approximately 75,while the MA Sport Management numbers less than 30, hence it is a very small proportion of the total. The first section will cover the context of formative CAA while section two looks at formative CAA’s within the sport management subject area, with a particular focus on current research and its limitations. The third section offers discussion on some of the future directions for formative CAA design and implementation. The final section summarises the main points and provides a self-assessment on the exercise.
Servicios y Seguridad, un enfoque basado en estrategias de ataque y defensa

This article describes the methodological approach of the subject Services and Security of the Bachelor's Degree in Information Technology and Services (Universitat Autonoma de Barcelona), which is taught at the Tomas Cerda Computer Science School. We propose an approach based on attack and defense strategies which are used in computer systems. Strategy models are the thread that relates how the rest of the topics as cryptography, security standards, threat modeling and risk assessment methodologies contribute in setting up a secure web service based system. The practical part includes laboratory sessions and development of a work of hacking. In the laboratory students learn to set up a web server application, to generate server and client's certificates, and to include security options into applications and web services. By doing the practical work students learn how to defend the system in a better way through the knowledge of the techniques and tools used by hackers to discover and exploit vulnerabilities of infrastructure and applications.
Female Technology Leaders Overcome Barriers to Climb the US Industry Ladder

Women represented 57% of the labor force, but only 20% in the technology industry (United States Labor Department Bureau of Labor Statistics, 2015). Therefore, we utilized narrative inquiry research design with feminism and gender role incongruity theories as theoretical frameworks to investigate five women’s experiences becoming leaders of major technology organizations. We collected data from interviews and documents. Data analysis revealed four major themes: climb your ladder, know your worth, discover your career, and nurture your vision. The findings suggested that the primary barriers for women entering and staying in the technology field were removed by intrinsic motivation augmented by personal persistence, passion for learning, creativity, and efficiency. The female technology leaders in this study shared valuable, diverse leadership perspectives that may benefit male technology leaders. All participants exhibited an ability to nurture team members and organization goals using soft skills to ameliorate the rigid and fast-paced technology industry.
