Advertencias Sanitarias y empaquetado neutro de productos de tabaco en la percepción de los salvadoreños

Introducción. El CMCT de la OMS, establece que una medida para disminuir el consumo de tabaco se encuentran las advertencias sanitarias, como medida relativa al empaquetado y etiquetado de los productos de tabaco. En El Salvador las regulaciones sobre el empaquetado, establecen advertencias del 50% sobre los productos de tabaco, ya sean en paquetes con forma regular o irregular. Objetivo. Conocer la percepción de la población salvadoreña sobre las advertencias sanitarias más grandes y empaquetado neutro en la intención de fumar y en desalentar el inicio al consumo de tabaco. Metodología. Estudio cualitativo realizado a través de grupos focales en tres segmentos poblacionales: adolescentes, jóvenes y adultos. La sistematización y procedimiento con el análisis de resultados de los grupos focales fueron realizados a través de la aplicación NVivo, Versión 10. Resultados. Las advertencias sanitarias actuales evocan sensaciones negativas a la población y las que generan mayor impacto son los pictogramas de niños afectados por la exposición al humo de tabaco ajeno. Existe un alto apoyo de la población para incrementar las advertencias sanitarias y es el empaquetado neutro el que posee mayor rechazo entre la población. Conclusiones. Se hace necesario rotar las advertencias sanitarias e implementar el empaquetado neutro como medidas costo efectivas para reducir el consumo de tabaco, por lo cual deben realizarse los esfuerzos necesarios para su implementación en El Salvador.
Investigation on the effect of mechanical vibration in mild steel weld pool

This study presents a new concept of a vibratory welding setup which can transfer the mechanical vibrations in the weld zone during Shielded Metal Arc welding (SMAW) process and can also produce the resonance frequency of 300 Hz. In the present investigation mild steel plates of 6 mm thickness has been butt welded using both conventional and vibratory welding conditions. Microstructure and the mechanical properties of the butt welded joints were evaluated, and the results were compared. Further, in order to optimize the process parameters of vibratory welding technique Taguchi and analysis of variance (ANOVA) technique have been adopted. The responses considered for analysis are hardness, ultimate tensile strength (UTS) and impact strength. The result of the study indicates that by applying the vibratory treatment during welding process the mechanical properties such as hardness, tensile strength and impact strength have been enhanced. Lastly, the obtained results are correlated from the results in the past researches.
Study of Transport Phenomena in Flowfield and Diffusion Media of a Proton Exchange Membrane Fuel Cell

Author(s): Mojica, Felipe Euyoqui | Advisor(s): Chuang, Po-Ya A | Abstract: Proton exchange membrane fuel cells (PEMFC) are a green electrochemical technology that is rapidly gaining traction in the automotive industry and the like. Major components to the fuel cell are the flow field plates and the porous gas diffusion media (GDM) that transport reactants to, and products away from the catalyst layer where the reactions occur to produce heat water and electricity. These components can enhance or hinder fuel cell performance, efficiency, and the rate of degradation via mass transport mechanisms, especially at high power output. Our work begins with a top-level examination of the three most common flow field channel distribution patterns used in research, the parallel channel, single channel serpentine and multiple channel serpentine designs, using both computational methods and lab-built fuel cells. Using multiple channels significantly improved gas distribution across the electrode area but faced water flooding issues due to the low pressure drop. To improve transport focus was then given to the flow channel design. We designed the wavy, 2D-nozzle, and 3D-nozzle channel designs which feature alternating width, height, and direction from inlet to outlet to alter the flow path. Using the limiting current method to quantify the oxygen transport resistance (OTR) we discovered that with our 3D-nozzle design OTR reduced approximately 12% versus the straight channel design at the same current draw. Additionally, the maximum power at high humidity conditions was increased from 1.6 to 2.0 Amp per centimeter square with Toray-060 GDM and 2.6 to 3.1 Amp per centimeter square with Freudenberg H23C8 GDM at 0.3 volts. The 3D-Nozzle design has shown improved OTR and value for further investigation and optimization with the potential of use in commercial PEMFC.

Fabrication of Al5083 surface hybrid nanocomposite reinforced by CNTs and Al2O3 nanoparticles using friction stir processing

In the present study, friction stir processing was adopted for surface treatment of Al5083 by incorporation of CNT and Al2O3 nanoparticles. Microstructural, mechanical and tribological properties of the surface of Al5083/CNT, Al5083/Al2O3 and hybrid Al5083/CNT/Al2O3 nanocomposite were investigated and compared. The friction stir processing yielded a nearly uniform dispersion of CNTs and Al2O3 nanoparticles, irrespective of nanoparticle reinforcements and their weight fraction. Microstructural observations revealed that Al2O3 nanoparticles have dispersed in different zones including intra-grain and grain boundary zones while, CNTs are pinned into grain boundaries during friction stir processing. From mechanical point of view, hybridization of CNT/Al2O3 enhances the hardness (126 HV at stirred zone), strength (UTS of ∼487 MPa) and also wear resistance of Al5083/CNT/Al2O3 nanocomposites. The enhancement is attributed to the presence and combination of features of both CNT and Al2O3 nanoparticles which are different in nature; one spherical oxide and one nanotube.
Dual carrier based PWM strategy for common-mode voltage reduction of three-phase voltage source inverters

A pulse-width modulation (PWM) strategy based on dual carrier is proposed to suppress the common-mode voltage (CMV) of three-phase voltage source inverters (VSIs). This strategy employs two triangle carriers with opposite phase to reduce the peak value of the generated CMV by avoiding zero voltage vectors. In particular, the effective phase range of the two opposite carriers is derived. The optimal initial phase of the dual carrier is determined through the output performance comparison of VSI. Finally, the experimental results are presented to illustrate the feasibility and validity of the proposed modulation strategy.
ASSESSING THE TRANSLATION OF PERSON REFERENCE FORMS IN A LITERARY TEXT: A CASE OF HARRY POTTER’S JOURNEY FROM ENGLISH TO VIETNAMESE

The study aims to assess the Vietnamese translation of English person reference forms, particularly “I - you” dyads in a literary text. To fulfill the purpose, House’s functional-pragmatic model (House, 2015), extended with Attitudinal resources of Appraisal theory (Martin & White, 2005), is adopted as the analytical framework for assessment. The data include 75 “I - you” dyads collected from “Harry Potter and the Philosopher’s Stone” (2014) and its Vietnamese translation “Harry Potter và Hòn đá phù thuỷ” (2016). The research findings show the translator’s attempt in selecting equivalents among the remarkably diverse system of person reference in Vietnamese to produce a functionally adequate translation in accordance with situational and cultural contexts of the target language. Grounded on research findings, target language-oriented strategy for English-Vietnamese translation of “I - you” dyads is proposed. Furthermore, the study has proved effective in extending House’s model (2015) with Attitudinal resources of Appraisal theory in order to explore the attitudes of the source text writer embedded in the original, serving the benefits of translation assessment in practice.
Framtagning av IoT-prototyp med LoRa och GPS

This thesis work has has been done at Sensative in Lund and the goal has been to build a prototype of a product which the company then may build further upon. The product aims to combine IoT with social responsibility by preventing drowning accidents with the data that is generated and sent via the product. Based of an initial description of the product provided by Sensative, the work then was divided into phases which include research, investigation, building of a prototype and programming of the system, and resulted in a prototype that can demonstrate the basic functionalities that the end product is suppose to have. The prototype can sense when it has been put into water by measuring the voltage between electrodes, and can also determine its position through the use of GPS and send the coordinates via the LoRaWAN protocol to a gateway once per hour or when an alarm triggers. Since the product is suppose to be worn by a user and powered by battery focus has also been put on trying to minimize power consumption by for instance using a motion sensor to determine if it is in use or not. The system is divided into a couple of distinct modes called Standby, Run, Warning, and Alarm where each mode contains its own set of code and conditions which will determine what happens next in the system. The system design also includes times when the microcontroller is put into to rest- or sleepmode in order to save further energy.
One-pot preparation of PS/silica hydrophobic coating by solution-casting using D-limonene as dispersing medium

Different polystyrene (PS) coatings were prepared and optimized by dissolving PS in D-limonene and subsequent dispersion of varying amounts of different chemically modified silica nanoparticles. Among the materials prepared, a PS coating filled with silica nanoparticles organo-modified with long alkyl carbon chains results in high hydrophobicity (120.8° as compared to bare PS coating – 67.0°) and excellent film-formation.
Increasing Operational Awareness using Monitoring-Aware IDEs

It is important to detect problems fast and to have a clear overview of what is happening within a system after deployment to maximize the uptime and functional quality of the system. Therefore it is necessary to increase the awareness that developers have of errors and logs. Increasing the awareness that developers have of errors and logs has a positive impact on finding problems and solving them. This thesis aims to use monitoring information to bridge the gap that exists between development and operations. We propose to do this by linking the logs to source code to provide this missing link between development and operations. We provide a theory for a monitoring-aware IDE which aims to tackle some of the challenges and enhance some of the practices that exist in the field. We implemented a monitoring-aware IDE and performed a field study to measure its effect. Our results show that a monitoring-aware IDE assists the developer in understanding the system, fixing problems in the code, and improving the monitoring code.
Analisando significados de capas da revista Raça Brasil: um estudo de caso à luz da semiótica social

No contexto brasileiro, tem havido um crescente interesse pelo uso do arcabouco descritivo da gramatica do design visual (KRESS e VAN LEEUWEN, 1996) como metodo de analise eficaz para uma abordagem semiotica social, especialmente quando se trata de sua conjugacao com o instrumental da gramatica sistemico-funcional (HALLIDAY eMATTHIESSEN, 2004) (BIAVATI e MAGALHAES, 2003; HEBERLE, 2004; FELIPE, 2006; SANTANA, 2006; dentre outros). O presente trabalho busca contribuir para a interface entre essas gramaticas e para o desenvolvimento dessa abordagem no contexto brasileiro, a partir da analise da capa das edicoes de novembro de 1996, 1998, 2004 e 2006 da revista Raca Brasil, uma publicacao direcionada ao publico negro. Utilizando ferramentas analiticas das referidas gramaticas, o principal objetivo desta pesquisa e analisar os significados representacionais, interativos e composicionais construidos pelo componente visual, bemcomo os significados ideacionais da chamada mais saliente e daquela referente a imagem da capa e investigar a relacao entre esses significados e a nocao de consciencia negra. Realiza-se uma comparacao entre os significados construidos por meio dos modos semioticos visual e verbal nas capas do corpus e investiga-se a existencia de mudancas discursivas nas edicoes e/ou nos periodos analisados. A analise aponta para ambivalencia da publicacao, a qual se manifesta em varios sentidos. Verifica-se um movimento por parte da revista no sentido de promover/fortalecer a consciencia negra dos leitores, por meio, principalmente, do estimulo a sua auto-estima, ao mesmo tempo em que se observa que as representacoes construidasmuitas vezes evocam discursos preconceituosos, que sao assimilados e reproduzidos. Alem disso, e possivel notar que, paralelamente a postura politizada da revista, caminha o interesse mercadologico, que parece determinar a construcao do layout da capa e mesmo o conteudo de determinadas chamadas. Por fim, as mudancas semioticas observadas suscitam as hipoteses de que, por um lado, a revista pode ter se consolidado como uma publicacao dirigida aos negros e, por outro, pode ter expandido seu publico-alvo, renunciando a segmentacao deste quanto a raca.
Enhancement of Mechanical Properties and Wettability of TiO2NT Arrays Formed in Simulated Body Fluid‐Based Electrolyte

Modified titanium nanotubes (TiO2NTs) coatings are grown in simulated body fluid (SBF) from Ticp and Ti6Al4V. The addition of 1% v/v of SBF to the electrolyte neither modifies film morphology nor the structural oxide characteristics for both metal substrates. However, an improvement in mechanical properties (hardness and elasticity model) and wettability is observed. From bioactive assay, a higher amount of fluorapatite was detected on the top of TiO2NTs prepared in SBF‐based electrolyte.
Der Steppeniltis (Mustela [Putorius] eversmanni soergeli Éhik) in der Niederterrasse der Leine und seine klimageschichtliche Bedeutung

Abstract. Ein aus Kiesen und Sauden der Leine-Niederterrasse gebaggerter Schadel eines Steppeniltis (Mustela [Putorius] eversmanni soergeli Ehik) wird zum Anlas genommen, die stratigraphische und okologische Aussagekraft dieser Iltis-Art zu uberprufen. M. eversmanni ist in Mitteleuropa bislang mit Sicherheit nur aus verschiedenen Zeitabschnitten des Wurm bekannt geworden, nie aus alteren oder jungeren Schichten. In der Gegenwart ist der Lebensraum des Steppeniltis ziemlich streng an die Halb- bzw. Kultursteppe und an die Vollsteppe gebunden, wobei die warmeren Teile des eurasiatischen Steppengurtels bevorzugt werden. Auch wahrend des Wurm kann die Art nicht unter wesentlich anderen Umweltsverhaltnissen gelebt haben. Es wird daraus gefolgert, das es auch in den Stadialen nicht nur trockenkalte, sondern auch trockenwarmere Phasen gegeben hat.
Corporate Control and Multiple Large Shareholders

Many firms have more than one blockholder, but finance theory suggests that one blockholder should be sufficient to bestow all benefits on a firm that arise from concentrated ownership. This paper identifies a reason why more blockholders may arise endogenously. We consider a setting where multiple shareholders have endogenous conflicts of interest depending on the size of their stake. Such conflicts arise because larger shareholders tend to be less well diversified and would therefore prefer the firm to pursue more conservative investment policies. When the investment policy is determined by a shareholder vote, a single blockholder may be able to choose an investment policy that is far away from the dispersed shareholders' preferred policy. Anticipating this outcome reduces the price at which shares trade. A second blockholder (or more) can mitigate the conflict by shifting the voting outcome more towards the dispersed shareholders' preferred investment policy and this raises the share price. The paper derives conditions under which there are blockholder equilibria.The model shows how different ownership structures affect firm value and the degree of underpricing in an IPO.
The Decision to Retain and Reduce Human Resources in Mergers and Acquisitions

Abstract The success of mergers and acquisitions are contingent upon organizational operations, legal structures, and fiscal responsibilities. Each of these areas requires a proper mix of human capital – people – assigned to carry out the objectives and goals of the emerging entity. Within the general knowledge of Mergers and acquisitions (M&As), research focusing upon these aspects of human capital have been lacking. This chapter adds to the current knowledge of M&A human resources by establishing a framework that can direct future research.
Use of Smartphone-Based Head-Mounted Display Devices to View a Three-Dimensional Dissection Model in a Virtual Reality Environment: Pilot Questionnaire Study

Background Virtual reality (VR) technology has started to gain attention as a form of surgical support in medical settings. Likewise, the widespread use of smartphones has resulted in the development of various medical applications; for example, Google Cardboard, which can be used to build simple head-mounted displays (HMDs). However, because of the absence of observed and reported outcomes of the use of three-dimensional (3D) organ models in relevant environments, we have yet to determine the effects of or issues with the use of such VR technology. Objective The aim of this paper was to study the issues that arise while observing a 3D model of an organ that is created based on an actual surgical case through the use of a smartphone-based simple HMD. Upon completion, we evaluated and gathered feedback on the performance and usability of the simple observation environment we had created. Methods We downloaded our data to a smartphone (Galaxy S6; Samsung, Seoul, Korea) and created a simple HMD system using Google Cardboard (Google). A total of 17 medical students performed 2 experiments: an observation conducted by a single observer and another one carried out by multiple observers using a simple HMD. Afterward, they assessed the results by responding to a questionnaire survey. Results We received a largely favorable response in the evaluation of the dissection model, but also a low score because of visually induced motion sickness and eye fatigue. In an introspective report on simultaneous observations made by multiple observers, positive opinions indicated clear image quality and shared understanding, but displeasure caused by visually induced motion sickness, eye fatigue, and hardware problems was also expressed. Conclusions We established a simple system that enables multiple persons to observe a 3D model. Although the observation conducted by multiple observers was successful, problems likely arose because of poor smartphone performance. Therefore, smartphone performance improvement may be a key factor in establishing a low-cost and user-friendly 3D observation environment.
