    Flow Visualization of The Buoyancy-induced Convective Heat Transfer in Electronics Cooling

    The aim of this work is to develop a simple optical method for the visualization of the natural convection flow generated in an electronic system during its normal operation. The presented experimental set-up allows to reveal local refractive index changes in a phase objects. A fringe pattern is acquired, through the cooling fluid under analysis, with a digital camera two times: the first one with the fluid at rest, the second one with the thermal load due to the electronic device normal operation. By the means of the MATLAB processing of the acquired images it’s possible to reveal the shape and the directions of the thermal flow lines for the cooling fluid. In this way we can obtain a deeper understanding of the optimal convection working volume or information for the optimization of the relative spatial positioning of the several electronic components in a complex electronic system, like a printed circuit board (PCB). The proposed technique has been tested on two typical heat extraction situations recurrent in the electronic devices. In this paper are presented the experimental results of the visualization of the convective flow, in air, for an heat sink and a power resistor.Comment: Submitted on behalf of TIMA Editions (http://irevues.inist.fr/tima-editions

    Supporting LGBTQ+ Survivors on Campus

    Get PDF
    Back by popular demand, last year\u27s Supporting LGBTQ+ Survivors on Campus has been revamped for the new state of Title IX. Historically, Title IX protections have provided a much-needed resource for addressing sexual violence on campus. However, the benefits of Title IX may not apply equally to all students in practice. This workshop will discuss how the history of Title IX raises questions about its applicability for all sexual violence, and ultimately explore strategies for addressing sexual violence in lesbian, gay, bisexual, trans, and queer (LGBTQ+) communities. How effectively does Title IX address same-sex violence? What other policy and programmatic options exist? How can we improve support for LGBTQ+ students? Attendees will learn a framework for analyzing policy changes that they can bring back to their campuses

    Joining multiple AEM datasets to improve accuracy, cross calibration and derived products: The Spiritwood VTEM and AeroTEM case study

    Get PDF
    Airborne time-domain electromagnetic methods (AEM) are useful for hydrogeological mapping due to their rapid and extensive spatial coverage and high correlation between measured magnetic fields, electrical conductivity, and relevant hydrogeological parameters. However, AEM data, preprocessing and modelling procedures can suffer from inaccuracies that may dramatically affect the final interpretation. We demonstrate the importance and the benefits of advanced data processing for two AEM datasets (AeroTEM III and VTEM) collected over the Spiritwood buried valley aquifer in southern Manitoba, Canada. Early-time data gates are identified as having significant flightdependent signal bias that reflects survey flights and flight lines. These data are removed from inversions along with late time data gates contaminated by apparently random noise. In conjunction with supporting information, the less-extensive, but broader-band VTEM data are used to construct an electrical reference model. The reference model is subsequently used to calibrate the AeroTEM dataset via forward modelling for coincident soundings. The procedure produces calibration factors that we apply to AeroTEM data over the entire survey domain. Inversion of the calibrated data results in improved data fits, particularly at early times, but some flight-line artefacts remain. Residual striping between adjacent flights is corrected by including a mean empirical amplitude correction factor within the spatially constrained inversion scheme. Finally, the AeroTEM and VTEM data are combined in a joint inversion. Results confirm consistency between the two different AEM datasets and the recovered models. On the contrary, joint inversion of unprocessed or uncalibrated AEM datasets results in erroneous resistivity models which, in turn, can result in an inappropriate hydrogeological interpretation of the study area

    Effects of varying sampling effort on the observed diversity of carabid (Coleoptera: Carabidae) assemblages in the Danglobe Project, Denmark

    Diversity relations among three stages of an urbanisation gradient were studied, using the Rényi scalable diversity index family and the Right Tail Sum (RTS) diversity. The rural areas were less diverse than either the urban or the suburban ones. The urban areas were more diverse considering the dominant species, while the suburban areas were more diverse considering the rare species. Next, we examined the impact of different sampling regimes on these diversity relations. A pulsating sampling method (sampling for 2 weeks every month) gave the same diversity ordering as continuous sampling. Further reduction in sampling period altered the diversity relations

The data collection method used in this research is the literature study method. The data analysis method used in this research is the descriptive qualitative method. The types of data that will be used in this study are divided into two, namely data relating to the existence of female characters. The results of the study show that there are three ways of existence of female figures, namely, fighting against the rules that oppress women, becoming an educated woman, and upholding the rights and roles of women

    Magnetic anomalies of steel drums: a review of the literature and research results of the INGV

    Get PDF
    The detection and evaluation of the status of disposal sites that contain hazardous waste materials is becoming an increasingly important element in environmental investigations. Close cooperation between the Istituto Nazionale di Geofisica e Vulcanologia (INGV; National Institute of Volcanology and Geophysics) in Rome and the Italian environmental police has resulted in numerous underground investigations of different buried materials. Among the geophysical investigation tools, magnetometry is the most effective, rapid and precise of all of the geophysical methods for localizing buried steel drums. Analysis of magnetic map anomalies can provide a variety of information about buried materials, including extension, distribution and depth, with processing of the acquired magnetic data. This information is also very useful in case of excavations that are aimed at the recovery of hazardous waste. This study determines the most relevant analyses reported in the literature, with modeling of magnetometric methods for environmental applications both theoretically and experimentally. Some studies and research results achieved by the INGV in relation to magnetic anomalies produced by buried steel drums are also reported, as found in field operations and as achieved from test sites

    Magnetic interactions: A multimedia interactive tutorial

    Get PDF
    Magnetic interactions, besides their intrinsic interest, constitute a didactical topic suitable to contextualize the fundamental physical concept of field. Moreover, the magnetic properties of matter, in particular ferromagnetism, are usually poorly dealt in italian high schools. By employing the Java programming language, we have developed an interactive tutorial allowing learners to explore the ways in which two GeomagTM magnets interact with a ferromagnetic sphere. The simulation (whose quantitative aspects are based on a magnetostatics transposition of the electrostatic’s method of images) interactively shows the sphere’s magnetization pattern as a magnetic dipole approaches to it. The interaction force between magnet and ferromagnetic object is also shown. The proposed tutorial is usefully employed to explain the so-called “Geomag paradoxes” (Defrancesco et al. 2007)

    Disección de los mecanismos subcelulares responsables del fenómeno de la escalera negativa y la apoptosis en la insuficiencia cardíaca usando un modelo celular

    La presente tesis está dirigida a examinar los principales mecanismos responsables de la disfunción contráctil que se observa en el corazón insuficiente. Específicamente, estudiaremos el papel que tiene las alteraciones en el manejo del Ca2+ en el desarrollo de la escalera negativa y en la pérdida de unidades contráctiles por apoptosis, ya que ambos fenómenos son de fundamental importancia en el deterioro de la función contráctil en la insuficiencia cardíaca. Esta disfunción contráctil que presentan los corazones insuficientes revela la incapacidad de los mismos para aumentar la fuerza de contracción frente a una mayor demanda, de modo que comprender las bases subcelulares y moleculares de estos fenómenos puede resultar en un importante avance en el desarrollo de nuevas herramientas terapéuticas. Esta tesis describe por lo tanto los resultados de dos trabajos experimentales, que aunque diferentes, están relacionados entre sí por un denominador común que es la disfunción contráctil de la insuficiencia cardíaca (IC). En el primero de ellos, el objetivo fue reproducir a nivel de un miocito cardíaco las tres alteraciones del acoplamiento éxcito contráctil (AEC) que se describen clásicamente en la mayor parte de los modelos de IC (disminución en la expresión de la SERCA2a, aumento en la expresión del NCX y aumento del la concentración de Na+ intracelular) y determinar si éstas mimetizan, asociadas o independientemente, una de las principales características de la IC como es el fenómeno de la escalera negativa. En el segundo, el propósito fue examinar si existe alguna relación entre estas alteraciones en el AEC y la apoptosis, que como ya se mencionó previamente, es una causa fundamental de la disminución de la contractilidad en la IC. Debido a que la disminución en la expresión del NCX (y no su aumento como ocurre en la IC) y la sobreexpresión de SERCA2a (y no su disminución, como ocurre en la IC) se asociaron a apoptosis, (Miyamoto, 2005; Vafiadaki, 2009), nos concentramos en el estudio del posible rol del aumento del Na+ intracelular en la producción de este tipo de muerte celular.Tesis digitalizada en SEDICI gracias a la colaboración de su autora.Facultad de Ciencias Médica
