    "File: Housing, 5/80/10M""To make a scale plan for each wall showing cabinets or equipment which will be placed against it draw wall length and height, then draw in windows, doors and other permanent features. Arrange cabinets and equipment elevation cut-outs on the wall to correspond to your kitchen floor plan. Draw or fasten cutouts on the wall plan."--First paragraph.Patricia Hilderbrand (Assistant Professor, Housing and Interior Design

    Betsy DeVos Is No Ruby Bridges

    So maybe you saw this cartoon that was drawn by Glenn McCoy for the Belleville (Ill.) News-Democrat under the headline Trying to Trash Betsy DeVos. If you didn\u27t, take a look. In the cartoon, of course, you see little Betsy DeVos walking to school, book in hand, surrounded by faceless men who are there to protect her. It seems to barely be working: there is profanity scrawled on the wall ( NEA !; Conservative !; an anarchy symbol) and what appears to be a really juicy, nasty tomato thrown against the wall. For context, you might also be interested in looking at this painting, because it\u27s the one that obviously inspired McCoy to draw his. [excerpt

    Magnetocaloritronic nanomachines

    Full text link
    We introduce and study a magnetocaloritronic circuit element based on a domain wall that can move under applied voltage, magnetic field and temperature gradient. We draw analogies between the Carnot machines and possible devices employing such circuit element. We further point out the parallels between the operational principles of thermoelectric and magnetocaloritronic cooling and power generation and also introduce a magnetocaloritronic figure of merit. Even though the magnetocaloritronic figure of merit turns out to be very small for transition-metal based magnets, we speculate that larger numbers may be expected in ferromagnetic insulators.Comment: Submitted to "Special issue: Caloritronics" in Solid State Communication

    Current induced domain wall dynamics in the presence of spin orbit torques

    Full text link
    Current induced domain wall (DW) motion in perpendicularly magnetized nanostripes in the presence of spin orbit torques is studied. We show using micromagnetic simulations that the direction of the current induced DW motion and the associated DW velocity depend on the relative values of the field like torque (FLT) and the Slonczewski like torques (SLT). The results are well explained by a collective coordinate model which is used to draw a phase diagram of the DW dynamics as a function of the FLT and the SLT. We show that a large increase in the DW velocity can be reached by a proper tuning of both torques.Comment: 9 pages, 3 figure

    An ode to joy : a season of grief

    Beethoven's Ninth in Bailey Hall the other evening, April 20, ending in an instant standing ovation by a clearly enchanted audience, was an unforgettable experience. And, like all such truly extraordinary events that are marked not only by artistic merit, but draw their power from the circumstances surrounding their creation or performance, it recalled others and enhanced their significance. I was reminded of a stellar performance on Christmas Day of 1989, only weeks after the unexpected fall of the Berlin Wall on November 9, that haunting date in German history. Few people believed it would ever happen. But now, suddenly, reunification in justice and freedom, as the truncated old national anthem phrases it, was within reach

    Non-topological Domain Walls in a Model with Broken Supersymmetry

    Full text link
    We study non-topological, charged planar walls (Q-walls) in the context of a particle physics model with supersymmetry broken by low-energy gauge mediation. Analytical properties are derived within the flat-potential approximation for the flat-direction raising potential, while a numerical study is performed using the full two-loop supersymmetric potential. We analyze the energetics of finite-size Q-walls and compare them to Q-balls, non-topological solitons possessing spherical symmetry and arising in the same supersymmetric model. This allow us to draw a phase diagram in the charge-transverse length plane, which shows a region where Q-wall solutions are more stable than Q-balls.Comment: Some discussion about the phase diagram added.

    Experimental and computational investigation of a new solar integrated collector storage system

    The paper discusses a combined experimental-numerical analysis of an innovative solar thermal device to be used as an Integrated Collector Storage (ICS) system providing domestic hot water. In this equipment the collector acts also as a storage unit, without requiring an external vessel. Due to its simple configuration, the ICS device was successfully used in several circumstances, especially in extreme situations such as in post-earthquake tent cities or to reach remote users in Africa. In order to assess the efficiency of this collector, the draw-off process was investigated measuring the value of the mean temperature of the water discharging from the tap as cold water filled the collector. In the present configuration the draw-off is not completely optimised and a detailed analysis was carried out in order to investigate the mixing of cold and hot water in the solar collector during the discharge phase. A series of thermocouples was placed in selected positions around the shield of the collector to investigate the evolution of the near wall temperature. Furthermore, a numerical analysis based on Large-Eddy Simulation (LES) of the mixing process inside the collector was carried out using an open source, in-house, finite-volume computational code. Even if some restrictive hypotheses were made on the thermal boundary conditions and the absence of stratification, the LES results gave interesting findings to improve the collector performance
