Authors: Ukibayev J.K. , Fomenko Sergey M. , Dilmukhambetov E.E. , Mansurov Zulkhair A. , Korkembai Zh.
Published: March 2017

In this paper the contribution of heterocoagulation of silica sols on powder materials to the formation of nanostructured forms of silicon oxide is presented. To a greater extent heterocoagulation is more appeared on the advanced surfaces of refractory particles and clay, and to a lesser extent on the particles of alumina and silica oxide, the surfaces of which contained significantly fewer active centers. Silica sols have positive effect on drying and firing modes of ceramic materials. It was established that the application of silica sol as binder in the preparation of aluminum silicate ceramics allows to reduce the firing temperature to 150-200oC with a simultaneous increasing of strength characteristics.

Published: March 2017

One-dimensional CdZnS nanostructures have been synthesized through the sublimation. Effect of high substrate temperature on morphology, structural and optical properties of these nanostructures has been studied. X-Ray diffraction peak intensity, lattice parameters, crystallite size decreased with an increase in substrate temperature. The morphology changed with the increase in the substrate temperature. Raman Spectroscopy confirmed the existence of constituent elements in CdZnS solid solution and an increase of Zn concentration with the rise in substrate temperature. The nanostructures exhibited strong photoluminescence emission in the green light region with a substrate temperature-dependent blue shift of 53 meV in emission energy. The Stoke’s shift energy raised from 45 meV to 302 meV as the substrate temperature increased from 510 °C to 550 °C. The stoichiometric deviancies, crystallite size, and quantum confinement effects resulted into an increase in the optical band gap from 2.4 eV to 2.71 eV. The results showed that CdZnS nanostructures could be potential candidates for nanostructure based optoelectronics and photovoltaic devices.

The scales of porous carbon materials usage are constrained by their considerably high cost. Therefore, development of new methods for production of porous carbon with the necessary complex of properties from cheap raw materials is actual. Also, porous carbon materials can be used for growth of carbon nanotubes as a matrices of catalyst particles. Herein, the method of fabrication porous carbon materials from waste of oil industry and their use as a matrices of catalyst particles to growth of CNT was developed. CNTs was synthesized by CVD using as hydrocarbon source - propan-butane gas mixture, as catalyst - Ni particles at 650°C, 700°C, 750°C, 800°C. Obtained carbon materials was investigated by Raman spectroscopy and by scanning electron microscope. Investigations on the properties of the obtained porous materials show soot particles sedimented in pores reduce well nanoparticles of metals from salts which act as nuclei for the growth of multiwall carbon nanotubes during pyrolysis of hydrocarbons by CVD method.

Published: March 2017

Aluminum and its alloys are the second used materials after steels due to their useful and attractive properties. In this paper, the effects of 4% copper addition to commercially pure aluminum grain refined by 0.15% vanadium are investigated. In particular, the effects of alloying on the mechanical behavior, fatigue life and strength are considered. The main objective of this study is to improve the mechanical strength and the fatigue strength of aluminum by refining its columnar microstructure. The obtained results show that the addition of 4% copper and 0.15%V to commercially pure aluminum significantly refined its grain size, and hence improve its mechanical strength as well as its fatigue life and strength.

Authors: Li Xia Shuang , He Wei Ping , Lei Lei , Zhang Teng Yun , Guo Gai Fang
Published: March 2017

In order to improve the corrosion resistance of Data Matrix (DM) code laser marked on aluminum alloy, the salt spray corrosion resistance was determined. First, the corrosion resistance of DM code laser marked by 3 different processing modes was investigated. Meanwhile, the SEM images and EDS data for modules and substrate of DM code are analyzed, which explains the differences of corrosion resistance for DM code by the 3 processing modes. A kind of laser combined electrochemical marking method for anti-corrosion DM Code mark was put forward, where a bare mark of DM code was created by direct laser marking in advance, and then a uniform, compact and protective oxide film was deposited on the bare mark by electrochemical oxidation to form the corrosion resistant mark. The results show that the corrosion resistance of laser direct marking DM code for different processing modes exist some difference. However, all the DM code samples become failure after at most 15.5 hours salt spray corrosion. The DM Code mark by the proposed method can withstand approximately 42 hours of salt spray corrosion, whose corrosion resistance improved 2-3 times.
Effect of Texturing on the Friction Characteristic of Carbide and Steel Material by Grinding Process
Authors: Perveen Asma , Liu Feng
Published: March 2017

In this paper, friction behavior of textured carbide and steel surface has been studied in order to investigate the effect of different patterns. Several simple textures have been fabricated using straight groove grinding wheel. By microstructuring, various spacing and height of the structure, we investigate the role of topography in terms of friction characteristic. The change of friction behavior has been tailored by grinding operation using straight grooved wheel and evaluated in terms of friction. Friction values were measured by Tribometer. Frictional properties of textured carbide and steel surfaces were assessed with the help of parallel steel slider with 2000g normal force under dry condition using four different sliding speeds. It is found from the experiment that except 30° and 90° angle patterns, rest of the patterns on carbide surfaces show friction reduction which is roughly from 0.15 to 0.13. On the other hand, similar textured patterns can reduce the COF from 0.17 to 0.13 in case of steel surface.
Update on Effectiveness of an Electromagnetic Feeding Tube–Placement Device in Detecting Respiratory Placements
Authors: Metheny Norma A. , Meert Kathleen L.
Published: March 2017

Background

Radiography is the accepted gold standard for testing feeding tube placement; however, an electromagnetic tube-placement device (ETPD) is sometimes used in lieu of radiography for this purpose. High success rates have been reported when the device was used by well-trained individuals. However, authors previously described 20 cases that occurred between 2007 and 2012 in which clinicians voluntarily reported inability to detect inadvertent tube insertions in the respiratory tract while using an ETPD.

Objective

To describe case reports to the US Food and Drug Administration’s Manufacturer and User Facility Device Experience (MAUDE) database between 2013 and 2015 regarding inadvertent respiratory placement of feeding tubes by operators using an ETPD.

Methods

The MAUDE database was searched for cases dated from January 1, 2013, through December 31, 2015, along with selected brand names. A total of 34 cases (25 after removal of duplicates) were located in which a feeding tube was inserted into the respiratory tract during insertions assisted by an ETPD.

Results

Sites of the malpositioned tubes included the right lung (n = 13), left lung (n = 6), unspecified lung (n = 4), and bronchus (n = 2). A pneumothorax occurred in 17 of the 25 misplacements; feedings were administered in 6 cases.

Conclusions

Many case reports involved clinicians failing to recognize tube misplacements in the respiratory tract while using an ETPD. These reports provide evidence that not all clinicians can use the device effectively to detect malpositioned tubes. Thus, one must continue to question the wisdom of eliminating radiographic confirmation of tube position before starting feedings.

Authors: Bradley Carolyn , Keithline Michelle , Petrocelli Meghan , Scanlon Mary , Parkosewich Janet
Published: March 2017

Background

Family presence during cardiopulmonary resuscitation in acute care is not widespread. Patients are not likely to be asked about their wishes for family presence or if they wish to be the decision makers about who should be present.

Objective

To explore the perceptions of patients on general medical units and to find factors independently associated with family presence during cardiopulmonary resuscitation.

Methods

A cross-sectional study of 117 randomly selected adult patients was conducted at an academic medical center. Participants were interviewed via a survey to obtain information on demographics, knowledge of cardiopulmonary resuscitation, sources of information on resuscitation, and preferences for family presence.

Results

About half of the participants agreed or strongly agreed that family presence during cardiopulmonary resuscitation was important (52.1%), that the participant should be the decision maker about who should be present (50.4%), and that the patient should give consent ahead of time (47.0%). Participants indicated that they would want an adult sibling, parents, or others (20.5%); spouse (14.5%); adult child (8.5%); close friend (5.1%); or companion (4.3%) present during cardiopulmonary resuscitation. Younger participants (20–45 years old) were 6.28 times more likely than those ≥ 66 years old (P = .01) and nonwhite participants were 2.7 times more likely than white participants (P = .049) to want family presence.

Conclusion

Patients have strong preferences about family presence during cardiopulmonary resuscitation, and they should have the opportunity to make the decision about having family present.

Authors: Prévost C , White H P
Published: March 2017

Natural Resources Canada (NRCAN) has the mandate of providing essential geographic information. An improved knowledge of our physical environment represents one of the basis of this mandate. The Arctic is an important, but difficult, area to study especially for
wetland monitoring. To reduce survey costs, researchers use surrogate sites located closer to home base office; this is why the Mer Bleue Bog, featuring open space / low tree coverage, typical of Arctic environment, is used as arctic surrogate study site.
This study site is used for the calibration - validation of various types of remote sensing data acquired by several project partners, and using satellite, airborne and Unmanned Aerial Vehicule (UAV) platforms.
Precisely geolocated products require ground control points (reference points) which are visible to the camera of the platform and whose geographic location is known with precision. To fulfill this need, high precision GPS surveys are required.
This document, highly illustrated, describes in detail the method and results of the GPS survey required for the geographic rectification of the numerous types of imagery, including Unmanned Aerial Vehicule photographs, acquired within the scope of this project in Mer Bleue bog in
2015.

ABSTRACT

Background:

The development of telemedicine has become a solution to provide healthcare service to the elderly while they remain in their homes. The unit of cost of healthcare service provided at home is lower than the unit of cost of Institutional Healthcare Service. The healthcare users' attitude and motivation are a fundamental factor for the acceptance of technology and behavior change. Still, motivation and attitude toward telemedicine, especially among elderly and their caregivers is not satisfactory.

Objectives:

The object of this study is to investigate the utilization of Telehomecare and its effect on user's attitude and motivation among caregivers of elderly population who are affected by chronic heart failure.

Materials and Methods:

Observational trial and quasi-experimental design with duration of 6 months were adopted. Intervention with the telemedicine platform that supports multispecialty teleconsultation and questionnaire for evaluating the effect of intervention “Use and attitude of current technology” were used.

Results:

The results after 6 months showed that expectations and attitude were improved, and the user's opinion about barriers was positive.

Conclusion:

We evaluated readiness and responsiveness of naïve user before and after 6 months during observational trial. The trial has demonstrated a unified user's opinion that the barriers to telemedicine's use are not so high that they cannot be overcome.

Published: March 2017

Mg-Sn alloys contain thermally stable Mg2Sn phase, and are proposed as heat-resistant alloys for automobile engine applications. In this study, the creep behaviour of Mg-5Sn alloy was investigated using impression creep technique. The impression creep tests were carried out under constant punching stress in the range of 80-320 MPa at temperatures 373-573 K, for dwell times up to 5 hours. The results highlight that creep of Mg-5Sn alloy was load and temperature dependent, i.e. increasing the load and temperature resulted in larger creep deformation and hence to higher creep rates. From the creep curves, the stress exponent and the activation energy were estimated and the creep mechanism was identified.
Passenger Comfort Analysis in an Automotive Considering a Magneto-Rheological Damper based Suspension
Authors: Soujanya R.B. , Jebaseelan D.D. , Kannan S.
Published: March 2017

Passengerâ€™s comfort in moving vehicles depends on the quality of the ride. The major cause of discomfort is the vibration transmitted to passengers due to the road irregularities. For a comfortable ride on a vehicle, vibration must stay within prescribed standards. In the present work, an attempt was made to show that, the vibrations can be limited with the use of Magneto-rheological (MR) dampers for varying road profiles than the passive damping methods. MR dampers are semi-active control devices that use MR fluids to produce controllable damping force as they are known to exhibit nonlinear behaviour. Multi body dynamic studies were done to study the response of the system using a quarter car model. In this paper, passive damping (viscous damping) was considered at natural frequency of 1.012Hz, the response of damping was observed after 10s and the acceleration was found to be 6m/s2. When MR damper is employed as the magnetic force increases, the response of the damping was better than the passive damping, at 1.2A it comes down to 0.55m/s2, and the vibration gets dampened after 1.75s. Hence, from this study it is concluded that the MR damper can be employed in automobile for better ride comfort.

Authors: Saravanakumar G. , Ravikumar L. , Yogaraju R. , Shravankumar C. , Arunkumar V.
Published: March 2017

The present investigation is aiming to get better squeeze film dampers which are normally used in high speed jet engines to minimize small amplitude large force vibrations. The investigation was started with squeeze film dampers employing conventional lubricating oils. Magneto rheological fluids are then used to enhance the viscosity characteristics of the fluid under the influence of magnetic fields in order to improve the damper performances. It is observed that the dynamic characteristics of the damper with magneto rheological fluids are enhanced. Further to improve the damper performance, few modifications in the damper assembly are carried out in this research work. A good amount of reduction in the amplitude of vibrations is observed in these modified squeeze film dampers coupled with magneto rheological fluids. This research work discusses dual and triple clearance squeeze film dampers and bump foil squeeze film damper, also subjected to variation in temperature. Dynamic characteristics are found to be decreasing as the viscosity of the fluid decreases with rise in temperature of the fluid.

In this, with and without coated specimens were prepared, then the microstructure, hardness, corrosion test were carried out. From the obtained test and analyzed results, it is found that the coated specimen having improved properties may contribute towards improved diesel engine performance. The results show less deformation after getting analyzed on ANSYS on the multilayer coated piston as compared to uncoated one.

This paper focused with extends the knowledge in studies and analysis of a new family of diode clamp multilevel inverter for electric vehicle application. The modified new diode clamp multilevel inverter concepts is related to reducing the components utilization, which has (n-1) switching devices, (n-3) clamping diodes, (n-1)/2 DC-link sources for achieving the same voltage level of traditional topologies. The proposed system is enhanced the voltage rating and reduce the total harmonics distortion in inverter output voltage. The switching scheme of Alternatively on Opposition Disposition pulse width modulation strategies is implemented to control multilevel inverter. The proposed system reduces the components utilization which has utilizes 45% of components for achieving the same level of voltage. The modified new diode clamp multilevel inverter is coupled with induction motor and its performance is validated with three phase induction motor for variable frequency drive. The inverter topologies performance has been investigated by prototype model.

Background and Significance: End stage renal disease (ESRD) affects approximately 660,000 persons in the US each year, representing a significant financial burden to the health care system and affected individuals. Telehealth approaches to care offer an important means of reducing costs as well as increasing autonomy for patients. Understanding patient satisfaction with telehealth provides a key towards eventual scalability.

Materials and Methods: Quarterly surveys were conducted to characterize satisfaction with remote biometric monitoring (RBM) for blood pressure, weight, glucose and peritoneal dialysis (PD)-specific educational online videos for ESRD patients using PD.

Results: Of 300 participants, 67% participated in the surveys and provided baseline and at least one follow-up assessment. The majority were 45 to 64 years of age (50.5%), Black (64.5%), married or living with significant other (52.0%), and had more than a high school degree (73.0%). RBM was associated with perceived autonomy and confidence in health care activities and decreased negative perceptions of PD care and ESRD. The majority of participants (80.1%) indicated that they were satisfied or completely satisfied with the system. Participants found that the interface increased confidence, reduced frustration, and related perceptions were significantly and positively altered (p<0.05) for each of the separate telehealth components. Educational videos were well utilized with nearly half of the participants (42.5%) reporting that they watched at least one of the videos, and the majority reporting that the videos seen had an overall positive impact on health. Discussion and Conclusions: Supplementing PD with telehealth has the potential to have a positive impact on patient perceptions of PD care and consequently improve clinical outcomes.
Barry Purves, el animador escénico
Authors: Gil Soriano Marta
Published: March 2017

La filmografía de Barry Purves es mundialmente conocida en los festivales de animación. Barry J C Purves (Woodbridge, Reino Unido, 1955), un aspirante a actor, se convirtió inesperadamente en animador tras realizar una prueba con marionetas para Cosgrove Hall Films, donde produjo trabajos comerciales durante más de diez años. Su revelación llegó con Next (1990), realizado para Aardman, y desde que funda su productora Bare Board Films se han sucedido en su filmografía obras maestras como Screenplay (1992), Rigoletto (1993), Achilles (1995) o Tchaikovsky (2011). Sus marionetas tienen gran realismo y vehiculan emociones poderosas; pero, sobre todo, los filmes personales de Purves establecen relaciones privilegiadas con toda la herencia de las artes escénicas, desde el teatro griego hasta el teatro clásico, la ópera, el ballet, e incluso el teatro de marionetas Bunraku. Purves no ha dejado de ser un artista polifacético que alterna sus filmes personales con producciones para el público infantil, y en años recientes ha diseñado y dirigido numerosos montajes teatrales, aplaudidos por crítica y público. En la siguiente conversación Barry J C Purves nos desvela las claves de su proceso creativo en la animación, y su personal relación con el teatro.

Authors: Carpizo Silvia , Moo Jose
Published: March 2017

En este artículo os presentamos The Neverending Wall, un cortometraje de animación dirigido por Silvia Carpizo, donde una serie de murales se animan por medio de técnicas digitales 2D y su integración con imagen real. Su argumento reside en un concepto universal de lucha, como un guiño a la esencia humana y un alegato a la expresividad individual. Un solo personaje, Seele, realizará su recorrido a través de la galería más grande al aire libre del mundo, la East Side Gallery, último tramo del conocido muro de la vergüenza, el muro de Berlín: 1300 metros de pared que aún se mantienen en pie.
The Neverending Wall ha sido producido gracias a las ayudas estatales del ICAA, CulturArts IVAC, y AGADIC. Fue seleccionado para representar a España en Euroconection de Clermont-Ferrand, punto de partida para obtener coproducción alemana y ser adquirido por Movistar+.
El cortometraje ha sido realizado en la Universitat Politècnica de Valencia, gracias al convenio colaborativo del Master en Animación de la UPV y la productora gallega Abano Producións, encabezada por Chelo Loureiro. En este artículo, su directora Silvia Carpizo y el asistente de dirección y supervisor y realizador de postproducción, Jose Moo, nos explicarán el desarrollo de este fascinante cortometraje y todas las fases de su creación.
Esculpiendo el fotograma. La elaboración de maquettes en el proceso de producción de largometrajes animados

Published: March 2017

Desde los inicios de la producción de largometrajes de animación hasta la actualidad, la escultura ha tenido un papel capital a la hora de abordar el diseño de los personajes en tres dimensiones, dado que las esculturas de pequeñas escala, que internacionalmente se denominan maquettes, ofrecen una ayuda inestimable para valorar su potencial visual desde todos los ángulos. Este trabajo se ha ido perfeccionado a lo largo del tiempo hasta convertirse en un rol indispensable dentro de cualquiera de los grandes estudios del cine animado. Las siguientes páginas, redactadas por el incansable cronista de la animación stop-motion, Adrián Encinas, darán cuenta de uno de los pasos creativos más espectaculares en el proceso de producir los grandes largometrajes de animación de todos los tiempos.
Nuevas formas de llevar una ópera al teatro. Un caso de estudio. La flauta mágica de la compañía 1927 y de Kosky: animación 2d, nuevas tecnologías digitales y estilo vintage
Authors: Sansone Vincenzo
Published: March 2017

La ópera, un género que a menudo se asocia al pasado, está más viva que nunca. Gracias a la aportación de directores y experimentadores provenientes del teatro, la ópera se ha convertido en uno de los campos por excelencia para la experimentación contemporánea, sobre todo en relación con el uso de nuevas tecnologías. Una verdadera paradoja. Un ejemplo es la puesta en escena de La flauta mágica de Mozart de la Komische Oper de Berlín, concebida y realizada por la compañía británica 1927 y por el director australiano Barrie Kosky en 2012. Es una representación atípica y extraña que utiliza las nuevas tecnologías del “video project mapping” y, al mismo tiempo, las técnicas de animación 2D —dibujos hechos a mano— con la intención de fusionar estéticas del pasado, sobre todo la del cine mudo y la de los orígenes de la animación, con la contemporaneidad. La intención de este trabajo es analizar la puesta en escena de esta obra en relación con los problemas actuales de la representación de óperas de repertorio.
Teatro cinema: espacio animado, narración gráfica y puesta en escena de la obra historia de amor
Authors: Conde Aldana Juan Alberto , Cristancho Hernández Juan Manuel
Published: March 2017

La utilización de proyecciones de cine y video en la puesta en escena dramática es ya un recurso común en el teatro contemporáneo, y la animación también forma parte de las posibilidades que ofrecen los lenguajes audiovisuales a la representación dramática. En este contexto, la compañía chilena Teatro Cinema ha sido pionera en la transformación del espacio dramático a partir de las nuevas tecnologías, ofreciendo composiciones espaciales híbridas que acercan el lenguaje teatral y el cinematográfico de formas inéditas. En este artículo proponemos un comentario de Historia de Amor, la obra de esta compañía que, además de lograr esta hibridación de la manera más eficaz, introduce también las estrategias expresivas del cómic, ofreciendo una especie de novela gráfica animada con actores en vivo, que expande la experiencia teatral, pero también inaugura para la animación un nuevo espacio de contacto con su público, en el ámbito de las artes vivas.
El estudio de dibujos animados CIFESA y las películas de Rigalt-Reyes
Authors: González-Monaj Raúl
Published: March 2017

La edad de oro de la animación española (1939-1955) —en la que se realizaron cerca de un centenar de cortometrajes y cinco largometrajes— siempre ha resultado interesante por el difícil contexto de posguerra en el que se desarrolló. Pero aún resulta más sugestiva si nos centramos en sus inicios, muchas de las veces autodidactas, y nos alejamos del epicentro animado que era Barcelona. Esta es la historia de los primeros animadores valencianos de los que hay constancia, el prácticamente desconocido equipo formado por Carlos Rigalt y José Mª Reyes.
Pero además, en el presente artículo al heroísmo pionero se le suma lo enigmático. Pues del trabajo de la misteriosa pareja, auspiciado por el Estudio de Dibujos Animados CIFESA en la que sería su efímera incursión en la producción propia animada de la major española por definición, no queda ni rastro. Obras, autores e infraestructura que no trascendieron y a los que el tiempo sepultó bajo un manto de olvido, pero que quizá merezcan un recuerdo por su condición de adelantados en una técnica, en un país y en un tiempo difíciles.
Reparar su memoria es el objeto de este trabajo que se inicia en Valencia, y que tras pasar por Madrid y Barcelona terminará sorprendentemente en Guatemala, tras los pasos de un artista multidisciplinar y de talento que fue elemento principal de la historia a la vez que cómplice de su olvido.
