Mammalian cell growth on gold nanoparticle-decorated substrates is influenced by the nanoparticle coating
Authors: Rosman Christina , Pierrat Sebastien , Tarantola Marco , Schneider David , Sunnick Eva , Janshoff Andreas , Sönnichsen Carsten
Published: December 2014

In this work, we study epithelial cell growth on substrates decorated with gold nanorods that are functionalized either with a positively charged cytotoxic surfactant or with a biocompatible polymer exhibiting one of two different end groups, resulting in a neutral or negative surface charge of the particle. Upon observation of cell growth for three days by live cell imaging using optical dark field microscopy, it was found that all particles supported cell adhesion while no directed cell migration and no significant particle internalization occurred. Concerning cell adhesion and spreading as compared to cell growth on bare substrates after 3 days of incubation, a reduction by 45% and 95%, respectively, for the surfactant particle coating was observed, whereas the amino-terminated polymer induced a reduction by 30% and 40%, respectively, which is absent for the carboxy-terminated polymer. Furthermore, interface-sensitive impedance spectroscopy (electric cell–substrate impedance sensing, ECIS) was employed in order to investigate the micromotility of cells added to substrates decorated with various amounts of surfactant-coated particles. A surface density of 65 particles/µm2 (which corresponds to 0.5% of surface coverage with nanoparticles) diminishes micromotion by 25% as compared to bare substrates after 35 hours of incubation. We conclude that the surface coating of the gold nanorods, which were applied to the basolateral side of the cells, has a recognizable influence on the growth behavior and thus the coating should be carefully selected for biomedical applications of nanoparticles.

Authors: Poullos Peter D. , Thompson Atalie Carina , Holz Grant S. , Edelman Lauren A. , Jeffrey R. Brooke
Published: December 2014

Ischemic colitis is a rare, life-threatening, consequence of mesenteric arteriovenous malformations. Ischemia ensues from a steal phenomenon through shunting, and may be compounded by the resulting portal hypertension. Computed tomographic angiography is the most common first-line test because it is quick, non-invasive, and allows for accurate anatomic characterization. Also, high-resolution three-dimensional images can be created for treatment planning. Magnetic resonance angiography is similarly sensitive for vascular mapping. Conventional angiography remains the gold standard for diagnosis and also allows for therapeutic endovascular embolization. Our patient underwent testing using all three of these modalities. We present the first reported case of this entity in a patient with a vascular connective tissue disorder.

Published: December 2014

A 14-month-old girl with pentalogy of Cantrell, a very rare congenital syndrome characterized by an epigastric omphalocele and malformations of the heart, sternum, pericardium, and diaphragm, underwent echocardiography and multidetector computed tomography before surgical repair of these deformities was attempted. These tests revealed multiple cardiovascular and noncardiovascular abnormalities. After surgery, the patient's cardiovascular status was stable. Although studies have shown that echocardiography, multidetector computed tomography, and magnetic resonance imaging may each play a role in the diagnosis and management of this condition, there are few data available to support the use of one imaging modality over another.

Discal cysts are extradural masses that communicate with the intervertebral disk and are a rare cause of lower back pain and lumbar radiculopathy. This case report describes a lumbar discal cyst, the diagnosis of which was confirmed on conventional discography, and which was treated with computed tomography-guided aspiration and steroid injection. Several reports have described this procedure, but only one in the radiology literature, and thus the purpose of this report is to remind the radiology community of the existence of this entity and propose a minimally invasive means of treatment.
Inadvertent intravesicular placement of a vaginal contraceptive ring: a case report and review of literature
Authors: Baker Kevin Scott , Barish Matthew
Published: December 2014

The NuvaRing® is a deformable, ring-shaped hormonal contraceptive device which is typically vaginally self-inserted by the patient.  While there are several potential side effects of usage, essentially all of them result from hormone delivery.  Complications from incorrect placement are rare.  We present the case of a 31 year old female who presented to our emergency department after being unable to retrieve a NuvaRing® for its scheduled removal.  CT scan showed a hypodense intravesicular NuvaRing® which the patient had inadvertently placed transurethrally 3 weeks prior.  Cystoscopy was performed and retrieval using a 3-pronged grasper was eventually successful after several failed attempts with an alligator grasper.  Our purpose in presenting this case is to introduce the reader to a rare complication of incorrect NuvaRing® placement, explain how this complication may occur as a result of NuvaRing® construction/functionality, describe how alternative cystoscopic instruments may aid in cystoscopic retrieval, and review the 3 other case reports of intravesicular NuvaRing® placement to discuss the utility of various imaging modalities when clinical suspicion of the complication is high.
Style is Fiction and Non-Fiction
Authors: Rizzato Ilaria
Published: December 2014

This chapter points out the advantages of stylistics in teaching translation and interpreting. By looking at the relationship between Translation Studies and Linguistics, it attempts to identify translation didactics as an area where the study of translation may profit from the methodology offered by stylistics. It explores the features of the stylistic method that may offer better insight into the translation process, such as its attention to the linguistic features and functions of texts, the systematic and critical analytical method provided, the emphasis on the variegated nature of text production and comprehension, and the hands-on approach that encourages the application of the stylistic methodology to real work situations. This chapter argues that training in the tools and methods of stylistics may enhance a translator's and an interpreter's motivation and professional performance and discusses the proposed teaching methodologies and strategies in the context of real-life teaching situations at a Master's degree level.

Intercultural Pragmatics and Text Typology
Authors: Seel Olaf Immanuel
Published: December 2014

This chapter intends to integrate culture, pragmatics, and text typology in translation teaching and to raise awareness on their significance in the translation process among translation trainees. First, it offers an overview of contemporary translation theory on translation teaching from a culture-sensitive, pragmatic-functional, and text typological point of view. Then, it applies intercultural pragmatics to Greek/German translation of the special text type “obituary.” The findings of this analysis lead to the conclusion that intercultural pragmatics not only reveals translational obstacles and difficulties but also offers solutions for the amelioration of translational competence in general and in Greek/German translation of “obituaries” in particular. The chapter ends with the presentation of a short text type-specific contrastive typology for obituaries in Greek and German culture. By that, the author intends to demonstrate the significance of text prototypologies on the basis of intercultural pragmatics for the development of the translational competence of translation students and of its implementation in translation teaching.

Authors: Li Yuan , Chang Kuo-Chung
Published: December 2014

This chapter examines factors that influence individual adoption of cloud computing measured by the intentions to use cloud computing for personal needs. Drawing upon the cloud computing and online service literature, it recognizes eleven antecedents to individual intentions to use cloud computing. An empirical test on undergraduate and graduate students shows that of these antecedents a person's attitude toward cloud computing, subjective norm, perceived behavioral control, and perceived usefulness have direct impacts on intentions, while other antecedents, including perceived ease of use, transferability of computer skills, vendor reputation, perceived risks, privacy concerns, security concerns, and concerns about vendor lock-in, have indirect impacts. The study expands the view on cloud computing adoption among individual users with a multiplicity of factors and an integrative framework, and it also highlights the tradeoffs between benefits and risks in adoption decisions.

Authors: Frisenvang Jakob , Pedersen Christoffer Ejerskov , Svejvig Per
Published: December 2014

This chapter addresses how Opus, a modified SAP solution delivered as a cloud solution, is interpreted, diffused, and adopted by Danish municipalities. The chapter is based on a theoretical framework using the organizing vision and diffusion of innovation theories. The authors study four Danish municipalities and the vendor of the Opus solution. They tell the history of Opus and analyze how it has diffused into Danish municipalities. The findings are that the diffusion is strongly influenced by regulative, normative, and cultural-cognitive pressures. Institutional processes play an essential part in the early and late diffusion of IS innovations and in the creation and evolution of an organizing vision such as Opus for Danish municipalities. The authors conclude the chapter with a discussion of how Opus as a technology could be categorized and follow this with future research directions.

A Research on the Correction Method of Two-Dimensional Bar Code Distortion on Free Radius Cylindrical Surface
Authors: Wang Cui Yan , Wang Wei
Published: December 2014

In order to solve the recognition problem caused by the distortion of two-dimensional bar code printed directly on the cylindrical units, a correction method has been put forward based on the combination of the information of space geometry calibrated in the camera and that of the image. Firstly, we should obtain the fixed parameters relating to the machine vision and then analyze how the two-dimensional bar code distorts on the cylindrical surface to find the correction method reversely. Since the cylindrical units vary from each other, it would be difficult to calibrate the radius of the units. Only by analyzing the perspective projection of the edge of the two-dimensional bar code on cylindrical surface and then founding the estimating function of radius can the parameters of radius be obtained from the image information. At last, the rationality of the algorithm is proved by experiments

Published: December 2014

In this paper, we present a new method for removing shadows from images. Different from traditional methods that explore pixel or edge information, we employ a shadow saliency region based approach. We combine the region saliency with the clustering algorithm to get shadow region with the entropy rate in an unsupervised manner. The shadow free image is recovered by relighting each pixel based on our lighting model, and any visible shadow boundaries in the image can be eliminated by the Bayesian framework. We show that our method is fast and can generate satisfactory results for images with shadows.

Authors: Hassan N. , Sanusi A. , Ahmad Azizah Hanom
Published: December 2014

A Na–ion conducting solid electrolyte system was prepared by using ball milling and sintering method. The electrical conductivity study was carried out as a function of NaI concentration by Electrical Impedance Spectroscopy technique and the maximum conductivity of (1.02±0.19)×10-4S cm−1at room temperature was obtained for the composition 0.50 NaI:0.50 Na3PO4. Further characterization was performed by using and Infrared (FTIR) technique. From FTIR spectra, the variation in the peak intensity and shifting is observed due to the presence of P–O and PO43−bands that had been shifted indicating changes in polyhedral structure which in turn led to the formation of conducting channel by corner sharing or through edges. The ionic transference number was found in the value of 0.92 which suggests that ions are the charge carriers. The optimum composition with the highest conductivity of the sample considered as a good candidate to be used as solid electrolyte in solid state sodium battery. The sodium battery with configuration: Na/NaI–Na3PO4/V2O4was tested by the discharged characteristic at a current of 1.0 μA. The solid state sodium batteries exhibited a discharge capacity of 144mAh/g.

Failure Mechanism of Ultra-High Pressure Fluid Control Products
Authors: Chen Xin Long
Published: December 2014

The square elbows used in oil and gas fields were often failed because of serious erosion. Some of the products even burst. In this paper, the failure mechanism of square elbow was investigated by using electron microscopy (OM), electron microscopy (SEM) methods. The research results show that the elbow products failed due to its low impact toughness after carburizing and quenching. The erosion angle is nearly ninety-degree. By increasing the tempering temperature, reducing the surface hardness and improving toughness, the serious erosion phenomenon can be effectively avoided. There are two main reasons of the elbow products burst. One reason is the high inclusion content of the material. The other is the low impact toughness. Raising the quality specification of materials can appropriate increase the low impact toughness after heat treatment. It is pointed out that the product would be more safety by improve its impact toughness.
Investigation of the Existence of Textile Materials as Pens from Painted Pottery
Authors: Tao Yuan , Yu Wei Dong
Published: December 2014

As soft materials, textile materials play important roles in primitive times. Through analysing the patterns in painted pottery, the article propose that the patterns can only be drawn by textile materials, so pens made of textile materials must have been existed in the New Stone Age. It can be deduced that there are two developmental stages of pens, the first is ‘the Old Pens’ stage, at which textile materials are directly used for drawing; the second is ‘the New Pens’ stage, at which textile materials and stick are bound together as pens. What’s more, New Pens predate the existence of painted pottery, as they are tools of drawing on painted pottery.
Magnetic Microparticles@UiO-67 Core-Shell Composites as a Novel Stationary Phase for High Performance Liquid Chromatography
Authors: Qin Wei Wei , Silvestre Martin E. , Franzreb Matthias
Published: December 2014

Metal-organic framework UiO-67 was explored as a novel stationary phase for high performance liquid chromatography (HPLC). UiO-67 was, for the first time, homogeneously coated on carboxyl functionalized magnetic silica microparticles at low temperature (45 °C) by using a recently introduced liquid phase epitaxy (LPE) process. HPLC runs using the synthesized core-shell microparticles as stationary phase showed baseline separation for three phenol derivatives, applying gradient elution using acetonitrile and water as mobile phase. It also showed that UiO-67 has the largest affinity for 2,6-dichlorophenol among the phenol derivatives tested. The comparison of core-shell microparticles with 20 and 55 layers, respectively, of UiO-67 grown on the magnetic silica core proof that the UiO-67 shell determines separation behavior. Therefore, the use of UiO-67 core-shell microparticles as a stationary phase combines the advantages of a thin, homogenous MOF shell showing fast kinetics and good separation efficiency with the advantages of spherical silica microparticle cores offering high mechanical robustness and moderate pressure drop.

Authors: Mohd Rashid Muhammad Ikram , bin Nik Mohammed Nik Fadhil , binti Ab Ghani Suliana , Mohamad Noor Asiah
Published: December 2014

The energy extracted from photovoltaic (PV) or solar thermal depends on solar insolation. For the extraction of maximum energy from the sun, the plane of the solar collector should always be normal to the incident radiation. Sun trackers move the solar collector to follow the sun trajectories and keep the orientation of the solar collector at an optimal tilt angle. Energy efficiency of solar PV or solar thermal can be substantially improved using solar tracking system. In this paper, an automatic solar tracking system has been designed and developed using DC motor on a mechanical structure with gear arrangement. The movements of two-axis solar trackers for the elevation and azimuth angles are programmed according to the mathematical calculation by using the Borland C++ Builder. Performance of the proposed system over the important parameter like solar radiation received on the collector, maximum hourly electrical power has been evaluated and compared with those for fixed tilt angle solar collector.

This paper presents a control system approach for hybrid illumination of administrative offices (225m2) at an university building located at a tropical zone. The main goal was to minimize the energy consumption of artificial lightings (fluorescent), by taking advantage of the high natural lighting level during a workday (8 a.m. and 6 p.m.). The control system devices used for each office are: presence sensor, dimming photocell and dimming ballasts, all them connected to the Andover Infinet Controller. By means of data analysis and daylight curves, energy consumption and financial savings are determined. Subsequently, the average energy consumption per square meter due to the hybrid lighting in the offices (8.5 kWh/m2/year) and typical illumination of the central campus (27 kWh/m2/year) were compared. It was demonstrated that a reduction of energy consumption of about 70%, 50% by daylighting and 20% by automation was obtained.

Experimental Study on Advanced Reburning for NOx Reduction by Pulsating Injection of Reburn Fuel
Authors: Lee Chang Yeop , Kim Se Won
Published: December 2014

Reburning technology has been developed to adopt various commercial combustion systems. Fuel lean reburning is an advanced reburning method to reduce NOx economically without using burnout air, however it is not easy to get high NOx reduction efficiency. In the fuel lean reburning system, the localized fuel rich eddies are used to establish partial fuel rich regions so that the NOx can react with hydrocarbon radical restrictively. In this paper, a new advanced reburning method which supplies reburn fuel with oscillatory motion is introduced to increase NOx reduction rate effectively. To clarify whether forced oscillating injection of reburn fuel can effectively reduce NOx emission, experimental tests were conducted in vertical combustion furnace. Experiments were performed in flames stabilized by a gas burner. The natural gas is used as both main and reburn fuel and total thermal input is about 40kW. The forced oscillating injection of reburn fuel is realized by electronic solenoid valve, so that fuel rich region and fuel lean region is established alternately. In the fuel rich region, NOx is converted to N2 by reburning reaction, however unburned hydrocarbon and CO is oxidized in fuel lean zone and mixing zone at downstream where slightly fuel lean region is formed by mixing of two regions. The NOx reduction rate increases up to 41% by forced oscillating reburn motion. And this paper makes clear that in order to decrease NOx when oscillating reburn fuel injection system is adopted, the control of factors such as frequency and duty ratio is very important.

Secondary Flows in Radial Diffusing Channels
Authors: Gopalakrishnan G.
Published: December 2014

An approximate method has been developed for the estimation of the secondary flow through a radial diffusing cascade. The basis of this numerical treatment is on the Reynolds Navier Stokes method.The theoretical development is based on the channel approach, in that the flow emerging out of the channel is assumed to consist of two sets of symmetrical vortices, which includes the shroud cross flow principle. The flow is considered to be ir-rotational and incompressible. This however is a bad approximation for high pressure recovery diffusers. The solution could be extended to compressible situations – approximate solutions only.

One way to increase the payload capability of quadrotor is to employ a team of quadrotors and control them in fix formation to carry large dimension payload. This is also known as force multiplication technique. Therefore, this work intends to explore a new concept to control a scalable team of quadrotors by introducing a supervisary quadrotor in a two tier architecture or in master-slave mode.Once the payload is lifted, the supervisory quadrotor will guide the team of quadrotors beneath it to the desired destination and gently put down the payload.. The advantage of this concept is that the control algorithm can be easily adjusted when a new team of more powerful quadrotors or even multirotor vehicles become available to carry the load. This is seen as an important development in pushing quadrotor technology for industrial applications. Furthermore, this type of system is more flexible because it is able to operate in both indoor and outdoor environment.
