Jacob Viner’s Reminiscences from the New Deal (February 11, 1953)
No full textThis paper presents and reproduces an unpublished oral history interview given by Jacob Viner in 1953. The interview released by Viner for the Columbia Oral History Project gives us a valuable opportunity to throw light on his advisory activity during the New Deal Era. In our introduction we attempt to make a critical appraisal of Viner's reminiscences and to state the contribution they can provide to our general knowledge of the period. In addition, we also attempt to find out some biographical and interpretative elements useful to understand Viner’s own vision and his contribution to important economic policy processes during the New Deal.

Swarming and complex pattern formation in <it>Paenibacillus vortex </it>studied by imaging and tracking cells
No full textAbstract Background Swarming motility allows microorganisms to move rapidly over surfaces. The Gram-positive bacterium Paenibacillus vortex exhibits advanced cooperative motility on agar plates resulting in intricate colonial patterns with geometries that are highly sensitive to the environment. The cellular mechanisms that underpin the complex multicellular organization of such a simple organism are not well understood. Results Swarming by P. vortex was studied by real-time light microscopy, by in situ scanning electron microscopy and by tracking the spread of antibiotic-resistant cells within antibiotic-sensitive colonies. When swarming, P. vortex was found to be peritrichously flagellated. Swarming by the curved cells of P. vortex occurred on an extremely wide range of media and agar concentrations (0.3 to 2.2% w/v). At high agar concentrations (> 1% w/v) rotating colonies formed that could be detached from the main mass of cells by withdrawal of cells into the latter. On lower percentage agars, cells moved in an extended network composed of interconnected "snakes" with short-term collision avoidance and sensitivity to extracts from swarming cells. P. vortex formed single Petri dish-wide "supercolonies" with a colony-wide exchange of motile cells. Swarming cells were coupled by rapidly forming, reversible and non-rigid connections to form a loose raft, apparently connected via flagella. Inhibitors of swarming (p-Nitrophenylglycerol and Congo Red) were identified. Mitomycin C was used to trigger filamentation without inhibiting growth or swarming; this facilitated dissection of the detail of swarming. Mitomycin C treatment resulted in malcoordinated swarming and abortive side branch formation and a strong tendency by a subpopulation of the cells to form minimal rotating aggregates of only a few cells. Conclusion P. vortex creates complex macroscopic colonies within which there is considerable reflux and movement and interaction of cells. Cell shape, flagellation, the aversion of cell masses to fuse and temporary connections between proximate cells to form rafts were all features of the swarming and rotation of cell aggregates. Vigorous vortex formation was social, i.e. required > 1 cell. This is the first detailed examination of the swarming behaviour of this bacterium at the cellular level.</p

JACOB CORNELISZ VAN OOSTSANEN IN STROSSMAYER GALERIE
No full textU jednoj poslijeratnoj akviziciji Strossmayerove galerije JAZU (ulje na drvetu 1,295 x 0,840 m), autor ovog teksta prepoznaje djelo Jacoba Cornelisza van Oostsanena (oko 1470-1533). Citira komparativni materijal iz Kassela i Berlina, pa predpostavlja da su zagrebački sveti Jakob i Katarina morali nastati oko 1515. godine. Aluzije na njemački renesansni krug slikara autor objašnjava popularnošću Durerovih grafika u Nizozemskoj, što je više nego očigledno u drvorezbarskom opusu Jacoba Cornelisza. Na osnovu prenaglašenog kontraposta unutar čvrste tektonske kompozicije, otvara se ovdje pitanje o maniri kao preteči manirizma. U daljem tekstu autor povezuje zaštitničku ulogu svetaca s ondašnjom pripadnošću Nizozemske španjolskoj kruni. Naime, u toplini i bogatstvu pejzaža iza svete Katarine, autor vidi urbanizirani Sjever, za razliku od dalekog, pustog i siromašnog krajobraza Španjolske u pozadini svetoga Jakoba.In an acquisition made by the Strossmayer Gallery of the Yugoslav Academy of Sciences and Art (oil on wood 1,295 x 0,840 m) after World War II, the author of this text recognizes a work by Jacob Cornelisz van Oostsanen (c. 1470-1533). He quotes comparative material from Kassel and Berlin, supposing that the painting of St Jacob and St Catherine in Zagreb must have originated about 1515. Allusions to the German circle of Renaissance painters are explained by the author as resulting from the popularity of Durer's prints in the Netherlands, quite evident in the woodcuts of Jacob Cornelisz. The overstressed counterpoint existing within this firm tectonic composition confronts us here with the question of manner as a forerunner of mannerism. The author further relates the protective role of the saints with the fact that the Netherlands were
ruled by the Spanish crown at that period: in the warmth and lusciousness of the landscape behind St Catherine the author sees an urbanized North, contrasted to the distant, barren and deserted Spanish vista in the background of St Jacob.ln einem in den Nachkriegsjahren fur die Strossmayer-Galerie der Jugoslawischen Akademie der Wissenschaften und Kunste in Zagreb erworbenen Gemalde (Oel auf Ho/z, 1,295xO,840 m) erkennt der Verfasser ein Werk des Jacob Comelisz van Oostsanan (um 1470-1533). Er fuhrt Vergleichsmaterial aus Kassel und Berlin an, und setzt voraus, daf3 das Zagreber Bild des hl. Jakob und der hl. Katharina um 1515 entstanden ist. Anklange an den Kreis der deutschen Renaissancemaler erklart der Verfasser mit der Volkstumlichkeit von Durers graphischen Werken in Holland, was auch bei den Holzstichen von Jacob Comelis klar zutage tritt. Aufgrund des uberbetonten Kontrapostes innerhalb einer festen tektonischell Komposition stellt sich die Frage der Manier als Vo ria uf erin des Manierismus. lm weiteren Text stellt der Verfasser die Patronatsrolle der beiden Heiligen in Verbindung mit der damaligen Zugehorigkeit von Holland zur Spanischen Krone. Er sieht namlich in der Warme und Vielfa ltigkeit des landschaftlichen Hintergrunds der hl. Katharina den urbanisierten Norden, im Gegensatz zu der femen, eins amen und wi1sten Landschaft Spaniens im Hintergrund des hl. Jakobs

Law take thy victim. Better watch out for J. Owen--he is apt to hand you a joke when you are least expecting it. He is the most popular man in the class, well versed in law, and a big brother to all the girls. Some day when he is a lawyer and all his friends take their troubles to him, as they do now, he may get past that big brother stage.
-The Kentuckian, 1915-----------------------------------
Jacob Owen Reynolds (February 13, 1893 - December 12, 1964) was born in Slaughters, Kentucky to Warren Lee Reynolds and Ida Katherine Goodson. Reynolds practiced law in Lexington after receiving his LL.B.. His brother, Goodson Reynolds (UK Law \u2720), joined his practice in the 1920s. Reynolds was, at one time, the president of the Lexington chapter of the Red Cross. He was also the author of a pamphlet titled History of Epworth Methodist Church, Lexington, Kentucky (published in 1960). He married twice--his wives were Lucille Howard (1935-1937) and Winnifred Starks (1940-1964).https://uknowledge.uky.edu/klapp_1915/1024/thumbnail.jp
CO2 capture through electrified calcination in cement clinker production
No full textThe cement industry has the second highest share of industrial CO2 emissions, and two-thirds of these emissions come from decomposing its key ingredient by the calcination reaction (CaCO3 → CaO + CO2). This thesis studied the electrification of the calcination process. Electrified calcination will produce a relatively pure CO2 stream, which can be sent for direct utilization/storage, thereby avoiding a separate CO2 capture plant.
The main aim of the work is to recommend a suitable design for an electrified calciner heated by resistance heating technology. The main aim is achieved by answering four key questions related to 1) impacts on the mass and energy balance, 2) technical feasibility, 3) heat transfer efficiency, and 4) design recommendations. The key questions are answered by performing a mass and energy balance using Aspen Plus, experimental studies of different calciner designs, 1-D and transient modelling of different calciner designs, and computational particle fluid dynamics (CPFD) simulations of a fluidized bed calciner design.
The mass and energy balance results show that the CO2 emissions can be reduced up to 78% by using an electrified calciner instead of a coal-fired calciner. Moreover, a hybrid system integrating an electrified calciner with an amine-based CO2 capture unit using only internal heat integration can completely decarbonize the cement industry (i.e., close to 100% reduction). Different calciner concepts require different levels of CO2 recycling in the calciner. Increased gas recycling increases the calciner energy demand as the recycling gas must be heated. The energy demand can be reduced with heat recovery from the recycling gas. Such heat recovery is especially relevant for high and extremely high gas recycling cases. Moreover, CO2 capture from an electrified calciner is better than from a pure amine-based capture system as it requires lower input of extra energy.
The entrained flow calciner requires more than 2000 heating rods working under high gas velocities, so this design is unlikely to be technically feasible. The rotary calciner designs are technically feasible but have scale-up problems.
The fluidized bed calciner operating with a binary particle mixture is in interesting concept. Fine raw meal particles are difficult to fluidize, but cold-flow experiments have demonstrated that a mixture of raw meal and coarse inert particles can be fluidized, and subsequently segregated. A design of such a calciner also seems promising at hot flow conditions, based on results from CPFD simulations. However, the fluidized bed design should be experimentally validated also at hot flow conditions.
The fluidized bed calciner has the highest heat transfer efficiency and the lowest surface heat loss as it has a high heat transfer coefficient and high heat transfer area per internal surface area of the calciner geometry.
To conclude, the fluidized bed calciner is recommended as it has the highest heat transfer efficiency, and the concept seems promising both from cold flow tests and from CPFD simulations. An electrified fluidized bed calciner design is proposed, and this can be experimentally tested in future work.publishedVersio
