Lubrication efficiency and die design in wire drawing

With the competitive challenge facing business today, the need to keep cost down and quality up is a matter of survival. One way in which wire manufacturers can meet this challenge is to possess a thorough understanding of deformation, friction and lubrication during the wire drawing process, and therefore to make good decisions regarding the selection and application of lubricants as well as the die design. Friction, lubrication and die design during wire drawing thus become the subject of this study. Although theoretical and experimental investigations have been being carried out ever since the establishment of wire drawing technology, many problems remain unsolved. It is therefore necessary to conduct further research on traditional and fundamental subjects such as the mechanics of deformation, friction, lubrication and die design in wire drawing. Drawing experiments were carried out on an existing bull-block under different cross-sectional area reductions, different speeds and different lubricants. The instrumentation to measure drawing load and drawing speed was set up and connected to the wire drawing machine, together with a data acquisition system. A die box connected to the existing die holder for using dry soap lubricant was designed and tested. The experimental results in terms of drawing stress vs percentage area reduction curves under different drawing conditions were analysed and compared. The effects on drawing stress of friction, lubrication, drawing speed and pressure die nozzle are discussed. In order to determine the flow stress of the material during deformation, tensile tests were performed on an Instron universal test machine, using the wires drawn under different area reductions. A polynomial function is used to correlate the flow stress of the material with the plastic strain, on which a general computer program has been written to find out the coefficients of the stress-strain function. The residual lubricant film on the steel wire after drawing was examined both radially and longitudinally using an SEM and optical microscope. The lubricant film on the drawn wire was clearly observed. Therefore, the micro-analysis by SEM provides a way of friction and lubrication assessment in wire drawing.

Drawing association rules between purchases and in-store behavior:an extension of the market basket analysis

Shopping behavior is often exclusively studied through consumer purchases, since they are an easily measurable ouput. Still, the observation of in-store physical behavior (paths, moves and actions) is crucial, as is the quantification of its impact on purchases. Using an innovative PDA tool to precisely record and time stamp consumer’s moves and gestures, we extend the classical Market Basket Analysis (MBA) by integrating this new kind of information. We draw associations not only from purchases but also from in-store consumer moves and actions. We compare results of our new method with classical MBA results and show a significant improvement.

A taxonomy of measures for consumer-based brand equity:drawing on the views of managers in Europe

Purpose: The purpose of this paper is to identify the components of consumer-based brand equity from the perspective of experts in brand management in the UK, Germany and Greece. Design/methodology/approach: Data were collected from semi-structured interviews with senior brand consultants and managers, five in the UK, five in Germany and five in Greece. Findings: The findings suggested four categories of measures which can be used to define brand equity. These are the consumers' understanding of brand characteristics; consumers' brand evaluation; consumers' affective response towards the brand; and consumers' behaviour towards the brand. Specific dimensions are identified as indicators of each category. Research limitations/implications: Although the focus of this study is Europe, data were only collected from the UK, Germany and Greece, countries representing three of the five European cultural clusters. The resultant taxonomy adds to the fragmented literature on brand equity measurement by proposing four categories to gauge brand equity. Practical implications: The suggested taxonomy provides indicators of a framework managers could use when assessing brand equity. Originality/value: There is little agreement on what constitutes brand equity and therefore measures of brand equity are fragmented. To date, the views of practicing managers have not been taken into account in research. This paper draws on the views of practitioners and academics to suggest a taxonomy of categories of measures for brand equity. © Emerald Group Publishing Limited.

Drawing as a technique to facilitate childrens memory

This study examined a technique to assist children to recall more information about witnessed events. Thirty-eight fourth-grade children from a public grade school in Miami Florida participated in the experiment. The participants watched a Red Cross demonstration and were interviewed one week later about details of the demonstration. All of the children were interviewed using a police style interview. In addition, half of the children were instructed to draw during the interview. The current study supported previous findings that the instruction to draw increased the amount of information recalled. The effect of drawing was greatest for high-visual events. In addition, the instruction to draw prompted an increase in non-verbal information, which had an unusually high accuracy rate.

Bennett Hall, 1938 drawing

Bennett Hall was named for Private Logan A. Bennett of the 62nd U.S. Colored Infantry which contributed money for Lincoln University;s founding. He was a life long resident of Jefferson City, Mo. , and remained an ardent supporter of Lincoln University. This two story brick building housed young women and was occupied in 1938. It is now the new phase of living and learning for students with a concentration in Agriculture and Natural Sciences.

Drawing in Duos: The Journeys and Intersections Collaboration Project Between Istanbul and Worcester

This paper focuses on a collaborative drawing project carried out between two undergraduate drawing courses, one in Ä°stanbul and the other in Worcester, during the Fall 2015 semester. Duos -teams of two working remotely- took turns to work on the same drawing in correspondence for three months by means of communication and sharing the changing images on-line with one another. The project introduced a collaborative method of learning based on drawing, initiated cultural exchange and cooperation. The role of drawing in the project was critical due to the direct but gradual nature of transmitting meaning onto paper. Outcomes of this project consisted of a flexible and playful creation process for students making use of the element of chance. They sought alternate ways to finalize a drawing and experienced the benefits of artistic co-production. The project has the capacity to inspire artists, instructors and others interested in creative partnership in different disciplines and can be of value as an educational model.

Siniestros de tránsito, los Grupos Relacionados por el Diagnóstico y los costos hospitalarios. Características clínicas y costos de 740 pacientes hospitalizados por siniestros de tránsito en el trienio 2012-2014 en La Asistencial Médica Departamental de Maldonado, Uruguay

Introducción: cada año, cerca de 1,3 millones de personas fallecen en el mundo a raíz de un siniestro de tránsito y estos siniestros tienen una repercusión económica del 1% al 3% en el Producto Nacional Bruto (PNB) respectivo de cada país. La mortalidad por siniestros de tránsito en Uruguay fue de 16 fallecidos cada 100.000 personas en los años 2012, 2013 y 2014; mientras que en el departamento de Maldonado fue de 24,3 fallecidos cada 100.000 personas en el mismo período. Objetivo: ser un aporte al Pilar 5, “Respuesta tras los accidentes” del Plan Mundial de las Naciones Unidas, brindando datos clínicos y de costos de los pacientes hospitalizados por haber participado en un siniestro de tránsito. Material y método: se trata de un estudio descriptivo y retrospectivo que analiza la actividad de internación en los sanatorios de La Asistencial Médica Departamental de Maldonado (AMDM) durante el trienio 2012-2014. Se identificaron los egresos de pacientes que participaron en un siniestro de tránsito en los mismos años. Se obtuvo el costo de cada uno de los egresos en el período referido y se lo comparó con el costo de los pacientes siniestrados. Los costos se obtuvieron utilizando las planillas de Estructura de Costos de Atención a los Socios (planillas ECAS) que se remiten oficialmente al Ministerio de Salud Pública (MSP) y la metodología de los Grupos Relacionados por el Diagnóstico (GRD). Resultados: los egresos totales fueron 27.610 con un promedio de estadía de 4 días. Los egresos por siniestros fueron 740, con una estadía promedio de 7,5 días, casi el doble de la estadía promedio, y con 851 días/cama ocupados en cuidados intensivos. El 77% eran motociclistas, el 65% de sexo masculino, con una edad promedio de 36 años. El costo de atención de estos pacientes es 2,5 veces más elevado que el costo del paciente promedio. Conclusiones: el proceso asistencial de los pacientes que han sufrido un siniestro de tránsito y son ingresados a un hospital es muy complejo y pone a prueba la continuidad asistencial. Se debería considerar los 7,5 días de internación en promedio y el costo 2,5 veces mayor de estos pacientes con respecto al paciente promedio como una oportunidad de mejora de la atención, creando equipos eficientes de trabajo interdisciplinario y una guía clínica específica para esta tipología de pacientes. Los mismos se están constituyendo en una entidad nosológica nueva y cada vez más frecuente que nos exige nuevas formas de atención.
