How Do We Understand Partnership Working? Experiences from a Telecare Project
Authors: Berge Mari S. 
Published: December 2016

AbstractImplementing telecare requires experience and knowledge from different disciplines and sectors; business, technology and care. The uptake of telecare has been slow, which is assumed to be caused by difficulties in co‐operation within telecare partnerships. This article presents a new approach to improve understanding of telecare partnerships. The approach builds on theories of trust and partnership working and is informed by rational choice theory.Within this article the approach is applied to recent experiences from a telecare project in Norway, to demonstrate how different ways of interpreting the complex social interactions in telecare partnerships yield new insight and understanding. Examples from the Norwegian project illustrate how different understandings of actions and choices affected trust and caused either improved or deteriorated co‐operation in the partnership. The partners that were able to develop trust through a common evaluation of the problems co‐operated better. However, when partners lacked or had insufficient knowledge, either of each other or of the situation, this led to disparate understandings that threatened trust and affected further co‐operation. The new approach presented here is helpful in analyzing and understanding the actions of different partners within a telecare partnership and identifying why things worked well or went wrong. The approach may have wider relevance for other partnerships.
Social Policy Instruments in Motion. Conditional Cash Transfers from Mexico to Peru
Authors: Jenson Jane , Nagels Nora 
Published: December 2016

AbstractSocial policy prescriptions for Latin America have shifted significantly over recent decades. This article tracks a process by which a conditional cash transfer (CCT) to mothers, begun in a Mexican programme with some pretensions to promoting gender equality, was standardized by international organizations, becoming a policy instrument characterized by gender sensitivity, but having little attention to equality. In addition to involving certification by international organizations, this standardization process framed the CCT as an instrument of social investment and was a decontextualization of the Mexican version that had been influenced by Beijing‐style international feminism. The third phase of this trajectory was take‐up of the standard model by Peruvian policymakers and employees of the Juntos programme who overlaid their long‐standing representations of their indigenous clientele onto a supposedly ‘modern’ social policy instrument, thereby rendering it both maternalist and neo‐colonial.

<p><strong>ABSTRACT. </strong><em><strong>Background:</strong></em> Dental materials, including dental amalgam, undergo macro-structural changes when exposed to high temperatures. Understanding those changes can be useful for dental identification and documentation when conducting medical-legal autopsies of burned, charred, or incinerated bodies to determine type of biomaterial and highest temperature reached. <em><strong>Purpose:</strong></em> Describe the formation of silver nodules on the surface of dental amalgams exposed to high temperatures, in order to identify patterns and reliable markers for forensic dentistry use. <em><strong>Methods:</strong></em> This was a quasi-experimental <em>in vitro</em> study that described the formation of silver nodules in a sample of 45 dental amalgam discs (brands: Contour® Kerr®, Admix® SDI®, and Nu Alloy® New Stetic®) and 45 occlusal fillings in premolars that were exposed to high temperatures (200º C, 400º C, 600º C, and 800º C). <em><strong>Results:</strong></em><strong><em> </em></strong> Silver nodules were evident on the amalgam surfaces between 200º C and 400º C and began to disappear at 600º C to form spheres and strips upon reaching 800º C. <em><strong>Conclusions:</strong></em> The formation and disappearance of silver nodules is a recurring feature of new-generation amalgam alloys exposed to extreme temperatures. Therefore, describing them can be used as a marker to identify materials and determine highest temperature reached by human remains.</p><p> </p>

Niños con hemofilia y su atención odontológica por estomatología pediátrica. Revisión de la literatura / Children with Hemophilia and their Dental Care by Pediatric Stomatology. Review of Literature
Authors: Grandas Ramírez Ángela Liliana 
Published: December 2016

<strong>ABSTRACT. </strong><strong><em>Purpose</em></strong>: To carry out systematic review of literature about diagnostics, severity, and dental treatment considerations of children with Hemophilia A. <strong><em>Methods</em></strong>: The search for articles and other document was conducted through the databases available at the National Library System of the National University of Colombia. The English and Spanish terms used in the search were “pediatric dentistry,” “hemophilia A,” dental care,” “coagulation factors,” and/or “coagulation disorders.” <strong><em>Results</em></strong>: The sample consisted of 29 articles that met the inclusion criteria. Hemophilia A is a congenital disorder caused by a deficiency of coagulation factor VIII. Treatment of hemophilia depends on its severity and focuses on avoiding risking life of children due to preventable bleeding by timely applying local therapies such as tranexamic acid or factor VIII, depending on dental needs. Dental treatment of hemophilia A should be interdisciplinary and must emphasize primary health care, health promotion, and prevention in order to avoid invasive dental treatments that could cause bleeding. In addition, treatments seek to maintain oral health and to provide quality of life to children living with hemophilia A.

Published: December 2016

<strong>Abstract. </strong><strong><em>Background: </em></strong>Child abuse was first described in 1868 by pathologist Ambrosio Tardieu, but it was until the last century when the role of the dentist became relevant to early diagnose this syndrome. Several studies have shown that close to 50 % of head and face trauma is caused by physical abuse of which lips are the most commonly injured site (54 %), followed by oral mucosa, teeth, gums, and tongue. Complications of certain oral pathologies may be related to abuse for negligence. Bite marks have been associated to sexual abuse combined with oral lesions that appear as a result of sexually transmitted diseases. Parafunctional habits such as dental clenching (bruxism) have been linked to psychological abuse. <strong><em>Purpose</em></strong>: An extensive and detailed literature review of the clinical characteristics and proper handling when providing dental treatment to a child, who is presumably being abused, was carried out. The aim is for a dentist to early detect, document, consult with other professionals, and report cases of child abuse to authorities.
Optimization of Looped Airfoil Wind Turbine (LAWT™) Design Parameters for Maximum Power Generation
Authors: Song Binhe , Banerjee Subhodeep , Syrovy George , Agarwal Ramesh K. 
Published: December 2016

The looped airfoil wind turbine (LAWT™) is a patented new technology by EverLift Wind Tecnology, Inc. for generating power from wind. It takes advantage of the superior lift force of a linearly traveling wing compared to the rotating blades in conventional wind turbine configurations. Compared to horizontal and vertical axis wind turbines, the LAWT™ can be manufactured with minimal cost because it does not require complex gear systems and its blades have a constant profile along their length [1]. These considerations make the LAWT™ economically attractive for small-scale and decentralized power generation in rural areas. Each LAWT™ is estimated to generate power in the range of 10 kW to 1 MW. Due to various advantages, it is meaningful to determine the maximum power generation of a LAWT™ by optimizing the structural layout.
In this study, CFD simulations were conducted using ANSYS Fluent to determine the total lift and drag coefficient for a cascade of airfoils. The k-kl-ω turbulence model was used to account for flow in the laminar-turbulent transition region. Given the lift and drag coefficients and the kinematics of the system, an analytical formula for the power generation of the LAWT™ was developed. General formulas were obtained for the average lift and drag coefficients so that the total power could be predicted for any number of airfoils in LAWT™. The spacing between airfoils was identified as the key design parameter that affected the power generation of the LAWT™. The results show that a marked increase in total power can be achieved if the optimum spacing between the airfoils is used.
Electrohydrodynamics (EHD)-Induced Flow in Different Channel Configurations
Authors: Ngo C. C. , Sanghvi M. , Patel J. 
Published: December 2016

Electrohydrodynamics (EHD) is the study of flow field induced by an electric field. The concept behind EHD is to transform electrical energy into kinetic energy. The induced kinetic energy can then be utilized for many applications such as chip-integrated cooling, drying in the food industry, reducing drag of aircrafts, spraying of dielectric material for printing, controlling particulate matter emissions as well as EHD thrusters and pumping. The focus of the present study is the use of EHD to induce flow in various channel configurations. The operation principle of an EHD pump is based on the interaction among electrically charged particles inside the dielectric fluid and their migration to the grounded plate. Corona discharge, produced by applied high voltage difference, is an electrical discharge brought on by the ionization of fluid surrounding the electrodes. For the current work, this applied voltage to the electrode is in the order of 10–30 kV generated by a DC power supply while the resulting electric current generated is very small in the order of μA to mA. EHD pumps are becoming more attractive for industrial application nowadays due to the lack of moving parts, simple and compact design with light structural weight as compared to conventional pumps or cooling fans. In addition, there is less operating noise and no vibration during the operation of EHD pumps.
The main focus of our present work is to perform an experimental study to determine the induced flow rate at different applied voltages using various channel and wire electrode configurations. The basic experimental setup consists of an EHD pump test section, a high-voltage power supply, an air velocity transmitter and a data acquisition system. EHD pump test sections with different geometries of channel (e.g., circular, square and rectangular channels with the same cross-sectional area) along with different wire electrode configurations were constructed and tested. Measurements were taken from the corona threshold voltage to the sparkover voltage. The objective of the present study is to evaluate various designs of EHD pumps by comparing the EHD pumping efficiency.

New equations for hydraulic efficiency conversion from a model to a prototype centrifugal pump including mixed and axial flow types have been developed and proposed in this paper. In order to establish a set of conversion equations applicable for all type numbers of pumps, the following factors related to the conversion equations were examined.
1) The ratio of scalable loss to total hydraulic loss was examined by using CFD (Computational Fluid Dynamics) analysis. The ratio is related with the effect of actual complex velocity distributions in the flow passages in the impeller and diffuser/volute casing.
2) The conversion equation was constructed by two terms dealing with flow passages in two major hydrodynamic components, impeller and diffuse/volute separately, where contributions of each component to the efficiency step-up was expressed explicitly.
3) The friction coefficient ratio between a model and prototype pump was expressed in a simplified equation, applicable for both hydraulically-smooth and transitional surfaces. This expression was found to be useful to determine the relationship between equivalent machined surface roughness and uniform sand roughness, as the friction coefficient diagram expressed for uniform sand roughness is used for conversion of hydraulic losses between the model and prototype pumps.
4) The difference between the friction coefficients for decelerating flow and for a flat plate with uniform flow was examined by CFD analysis, and it was found that the friction coefficient for a flat plate can be used for the conversion without causing any substantial deviation.

When a material spreads in turbulent flow, areas with high concentration are formed by the local turbulence. These high concentration islands can lead to heavy damage. In this study, the high concentration areas are extracted as pulses by a conditional sampling technique, and statistical analysis were performed in order to investigate the difference between the pulses and concentration plume.
Assuming homogeneous flow, a series of images by Planar Laser Induced Fluorescence and Particle Image Velocimetry techniques are acquired at several downstream positions. For PLIF images, a conditional sampling technique is used to extract the high concentration areas. For simultaneous PIV and PLIF images, wavelet analysis is performed to probe into the relationship between high concentration pulses and velocity fluctuation.
Turbulent diffusion coefficient of the high concentration areas is found to increase with the downstream distance whereas that of the concentration plume is constant, which implies that the diffusion process of the pulses differs from that of the plume. Besides by wavelet analysis result, it is indicated that concentration fluctuation in the pulses is negatively correlated with streamwise velocity fluctuation. It is concluded that high concentration pulses and plume have different generative mechanisms.
Optimization of High Pressure Pump Flow Passages Based on Adjoint and CFD

Published: December 2016

In order to improve overall performance of a turbomachinery, it is important to reduce losses of stationary flow passages, such as diffusers and return channels, as well as impellers. For multi-stage pumps, to achieve high uniformity of the inlet flow of the latter impeller can prevent degradation of subsequent performance.
A two stages high pressure pump which was developed by the authors applied vaned diffuser sections located downstream of the first stage impeller and second stage impeller. The vaned diffusers can be replaced to fit the required specification of operating condition. This design is able to help pumps share the casings so that customers can purchase our products at a low cost.
However, the loss of the first stage diffuser section and crossover downstream of the first stage diffuser to the second impeller is large, so that it has a negative impact on overall performance of the pump. It was difficult to reduce loss of the both sections by conventional way such as trial and error approach by modifying geometrical parameters. If we try to reduce the loss of the diffuser section, loss of the crossover passage increases.
We therefore applied a technology called Adjoint method to the design optimization of the diffuser and crossover sections of the pump. The adjoint method has recently been put to practical use. By using this method it is possible to obtain a complex three-dimensional shape for realizing an optimum flow field in a very short time while maintaining a high degree of freedom.
In this study two objectives were specified in the design optimization of the stationery sections; one is to increase the uniformity of the flow field at the inlet of the second stage impeller and the other is to minimize the loss of the first stage diffuser and crossover passage. In the optimization process, the change of sensitivity of the geometry deformation to the weights of objective functions was analyzed by sensitivity maps. The sensitivity maps show directions of the geometry modification depending on the objectives. The geometry in this design was optimized with 50% - 50% weighting ratio between flow uniformity and pressure loss. The loss of the vaned diffuser and crossover passage, velocity uniformity at the outlet of the crossover passage were verified with Computational Fluid Dynamics (CFD). The improvement of pump stage performance was expected by the optimization.
This optimization design procedure applying Adjoint method is effective to improve overall performance of a two stages high pressure pump which has complex three-dimensional flow passages.
