description: Starting from the three-dimensional setting, we derive a limit model of a thin magnetoelastic film by means of Γ-convergence techniques. As magnetization vectors are defined on the elastically deformed configuration, our model features both Lagrangian and Eulerian terms. This calls for qualifying admissible three-dimensional deformations of planar domains in terms of injectivity. In addition, a careful treatment of the Maxwell system in the deformed film is required.

description: In Puerto Rico, arracacha or apio is a minor crop planted for its yellowfleshed corm. The climatic requirements of this crop restrict its commercial production to high elevations where ultisols are common. Previous studies did not examine the amount of nutrients that must be supplied by the soil-fertilizer combination for optimum crop development and yield. The objective was to estimate arracacha's macronutrient uptake in a soil typically used for its production. The experiment was planted on a Humatas soil (Typic Tropohumults) under rain-fed conditions. Three levels of Κ fertilization were used (45, 90 and 135 kg/ha). Yield and plant fresh weight were recorded at harvest; then the plant parts were oven dried. The nutrient concentrations in the tissues were obtained to estimate nutrient uptake. Neither yield, plant parts fresh and dry weight nor nutrient concentrations in tissues were affected by the level of Κ fertilization. Fresh corm yield was 4.8 t/ha. On a dry weight basis, the crop harvest index was 0.81. Except for K, the nutrients were more concentrated in the leaf lamina. Uptake of Ν and Κ were the highest, whereas Ρ and Ca uptake tended to be intermediate between the N-K group and Mg uptake. Nutrient harvest indexes exceeded 0.35.

description: We focus on the Penrose's Weyl Curvature Hypothesis in a general framework encompassing many specific models discussed in literature. We introduce a candidate density for the Weyl entropy in pure spacetime perfect fluid regions and show that it is monotonically increasing in time under very general assumptions. Then we consider the behavior of the Weyl entropy of compact regions, which is shown to be monotone in time as well under suitable hypotheses, and also maximal in correspondence with vacuum static metrics. The minimal entropy case is discussed too.

description: Portugal ist von der Lage am Atlantik geprägt. Die geschichtlichen und gegenwärtigen Entwicklungen des Landes stehen eng im Zusammenhang mit der Lage am Atlantik. Die portugiesische Bevölkerung hat sich nah an der Küste angesiedelt. Durch die Veränderung der Küstenstruktur aufgrund der Erosion wird der Lebensraum nach und nach beeinflusst. Der Klimawandel verstärkt die Erosion der Küste und lässt dies zum Problem für Bewohner und Touristen werden. Das Projekt 'OFFSHORE' thematisiert die Veränderung der Küste und beinhaltet die Planung eines Gebäudes für Küsten- und Meeresforscher sowie für Besucher. Geplant wird ein Ort um zu arbeiten, um sich auszutauschen und um als Besucher zu beobachten und zu lernen. Der Bauplatz befindet sich an der Küste, in der Nähe der Kleinstadt Ericeira, 45 km nördlich der Hauptstadt Lissabon. Durch die Platzierung im Wasser, setzt sich das Gebäude den Kräften des Atlantiks aus und lässt die erodierende Küste weitgehend unberührt. Die auftreffende Energie wird über Turbinen nutzbar gemacht und versorgt das Gebäude mit Strom. Für die Forschung bietet das Gebäude Arbeitsbereiche, Labore sowie ein Auditorium und Seminarräume. Für die Besucher gibt es einen 'Erlebnisweg' durch das Gebäude, entlang an Ausstellungsflächen und Situationen zum Beobachten der Natur. Ein für jeden zugängliches Café sowie verschiedene Aussichtsplattformen befinden sich im oberen Bereich des Gebäudes.
description: The Atlantic Ocean has a strong impact on the Portuguese country. Historical as well as present developments are often influenced by the situation close to the coast. This living environment is affected due to the changing of the coastal structure caused by coastal erosion. Nowadays the erosion is enhanced by the climate change and leads to be a problem for the inhabitants as well as for tourists. The project 'OFFSHORE' focuses on the changing structure of the Atlantic Coast. The planning includes a building for reseachers and for visitors. It is a place to work and to communicate as well as for visitors to learn and to explore the topic. The site is located at the coast, near the town Ericeira, about 45 km north of the capital Lisbon. The building exposes itself to the power of the sea and place itself in the water, in front of the eroding coast. Thus it let the coast nearly untouched. Turbines in the building exploit the energy of the waves for electricity. The building exists of working space, laboratories as well as an auditorium and seminar rooms for the researchers as well as space for the visitors. They pass through the building along a walkway until underwater level, passing by exhibition space and situations for observation . On top of the building there is a public café and different lookout platforms.

description: In order to better understand the role of grazed tropical grass pastures in an intensive Caribbean milk production system, research was initiated in 1996 to study the current grazing management and feeding of lactating dairy cattle in Puerto Rico's dairy industry. Information from the census of 450 dairy farms in Puerto Rico was obtained from official documents. The census data pertained to farm location, pasture acreage, herd size, milk fat test results, and concentrate feed purchases. A representative sample of 100 farms was selected for survey and a subsample of 22 farms chosen for a series of on-farm visits. The survey included pasture management, grazing schedule, and feeding program of the lactating cattle. The series of on-farm visits were used for forage sampling to evaluate the pasture as a feed resource. Forage sampling results indicate that forage nutritive value (14- 24% crude protein and 59-72% in vitro digestibility) was higher than expected and forageon- offer (1.4 - 7.3 Τ DM/ha) could support more intensive utilization of pasture. Of 67 farms responding to the survey, almost all were practicing rotational grazing with hign productivity pasture species - stargrass being dominant on 78% of farms. However, relatively low stocking rates, high levels of concentrates fed (>10 kg/cow) and the island-wide milk butterfat concentration of -3% indicate that farms needing to reduce feed costs could make greater use of their forage resources.

description: The phase diagram and the location of the critical endpoint (CEP) of lattice QCD with unimproved staggered fermions on a $N_t=4$ lattice was determined fifteen years ago with the multiparameter reweighting method by studying Fisher zeros. We first reproduce the old result with an exact algorithm (not known at the time) and with statistics larger by an order of magnitude. As an extension of the old analysis we introduce stout smearing in the fermion action in order to reduce the finite lattice spacing effects. First we show that increasing the smearing parameter $ρ$ the crossover at $μ= 0$ gets weaker, i.e., the leading Fisher zero gets farther away from the real axis. Furthermore as the chemical potential is increased the overlap problem gets severe sooner than in the unimproved case, therefore shrinking the range of applicability of the method. Nevertheless certain qualitative features remain, even after introducing the smearing. Namely, at small chemical potentials the Fisher zeros first get farther away from the real axis and later at around $aμ_q = 0.1 - 0.15$ they start to get closer, i.e., the crossover first gets weaker and later stronger as a function of $μ$. However, because of the more severe overlap problem the CEP is out of reach with the smeared action.

description: Zersiedelung und der damit einhergehende steigende Flächenverbrauch sind seit Jahren ein oft diskutiertes Thema. Der für diese Arbeit herangezogene Entwurfsstandort Mattersburg befindet sich in einer wachsenden Region und ist damit vor die Herausforderung einer effizienten und nachhaltigen Nutzung seiner Flächen gestellt. Der erarbeitete dreigeschossige Entwurf in Holzbauweise dient der Nachverdichtung im Ortskern und stellt Platz für unterschiedliche Nutzungen zur Verfügung. Durch eine barrierefreie Ausführung und ein flexibles Gebäudelayout, welches sich bis zur Haustechnik durchzieht, wird eine leicht adaptierbare und somit auf eine lange Nutzungsdauer ausgelegte Gebäudestruktur geschaffen. Die Konstruktion besteht aus vorgefertigten Elementen, welche in Systembauweise kombiniert werden können. Der somit entstandene Prototyp beinhaltet die Funktionen Wohnen, Gewerbe, sowie Nebenräume und Stellplätze für Autos. Die gesamte Dachfläche ist nutzbar, barrierefrei zugänglich, teilweise bepflanzt und gibt die versiegelte Grundfläche an einer anderen Stelle wieder frei. Die Gebäudetypologie soll als Beispiel dienen, wie Verdichtung im ländlichen Raum funktionieren könnte.
description: Urban Sprawl and the increase in land consumption has been a heavily discussed topic over the last few years. Mattersburg, the location of the project, is situated in a dynamically growing region and is therefore facing the challenge of using its land resources efficiently and sustainably. The design is a three-story wooden construction that offers space for different functions and serves the purpose of densification in the town center. A barrier-free and flexible building layout up to the building services, allows the project to be easily adaptable and therefore to be prepared for a long life-time. The construction consists of prefabricated components, which can be combined as modular systems. The resulting prototype contains living- and business spaces, utility rooms as well as parking spaces for cars. The roof area has a barrier-free access, is partly planted with bushes and trees and is in its entirety useable. The building topology can be seen as an example of how densification could work in rural areas.

description: Dopo la fine del sistema di fede, di Bretton Woods in un regime di cambio liberamente fluttuante, e in particolare la completa politica di laissez-faire degli Stati Uniti dopo il 1980, è stata sostenuta da una letteratura vasta e influente - la cosiddetta "teoria il punto della cambio "- che ha avuto predominio quasi assoluto nel campo. Il presente lavoro è di natura teorica in primo luogo, richiamando l'attenzione sul recente cambiamento drastico di opinione per quanto riguarda l'efficienza dei mercati dei cambi, delle aspettative e speculazioni. In contrasto con la credenza precedentemente detenuta, gli agenti che anticipano il mercato sono ora accusati di inefficiente, se non il comportamento irrazionale; si dice che essere mal interpretare o violare i "dati concreti", che dovrebbero portare il mercato sul sentiero di equilibrio. Secondo l'autore, questa nuova vena è impegnativo, ma il nuovo "cattivo" deus ex machina è convincente come i suoi predecessori "buoni". Così, l'attenzione è proprio sui fattori fondamentali della dinamica dei tassi di cambio nel contesto attuale di finanza integrata Lowing the end of the Bretton Woods system faith in a freely floating exchange rate regime, and in particular the complete Laissez-faire policy of the US after 1980, was supported by a large and influential literature - the so-called "stock theory of the exchange rate" - which has had almost absolute dominance in the field. The present work is of primarily a theoretical nature, calling attention to the recent drastic change of opinion regarding the efficiency of foreign exchange markets, of expectations and speculation. In contrast to the previously held belief, agents that anticipate the market are now accused of inefficient, if not irrational behaviour; they are said to be misinterpreting or violating the "hard data" that should lead the market on the path of equilibrium. According to the author, this new vein is challenging, yet the new "bad" deus ex machina is as unconvincing as its "good" predecessors. Thus, the focus is precisely on the fundamental factors of the dynamics of exchange rates in the current environment of integrated finance. JEL: F31, E42

Memory and identity (de)construction : an a/r/tographic act of inquiry
Creators: name: Hudson, Laura Gwynne
Publisher: name: University of British Columbia
Year: 2011

description: This text documents an a/r/tographic act of inquiry into memory and identity (de)construction. Speaking in, through, and of images the work physically situates itself in spaces uncharted. Meaning asserts and reveals itself between words, creating an other-text which defies boundaried definitions in its resistance to be known. That which we seek to map or mark eludes us. Knowledge is displaced in its representation. It is our longing for meaning which paradoxically interferes with its own processes. Spaces (dis)lodged between borderlands (Irwin 2004) shift and elude our grasp. The work resists that which it seeks to define and erases that which it seeks to name. It calls upon us to create space for doubt and unknowing within our own longing for understanding(s). If, as Grumet (1996) asserts "education is about a human being making sense of her life" (17) we must be aware of the ways curricular directives "do and do not stand for our experience" (19). The crisis of modernism is that we exist as fractured selves (Pinar 1996) within curricular landscapes which cut us off from our own identity (24). Pinar claims that "understanding curriculum as the revelation and construction of identity implies understanding education as a form of social psychoanalysis... (American) identity is constructed partly by denial, by maintaining fictions" (25). I view curriculum as traumatized text - that which refuses to be 'known' by the curriculum serves to subvert, bury and deny the learner's knowing. Absence of authentic dialogue creates gaps in the curricular landscape which serve to silence and partition off knowing - essentially, the learners are partitioned off from themselves. The work calls upon us to re-imagine curriculum as the space between learner and text/image, where meaning is continually (re)(de)constructed in the fissures of lived experience. It calls upon us to dwell (Aoki 1993) in spaces of uncertainty and ambiguity - spaces for possibility. If wisdom begins in wonder (Socrates) as I believe it does, we must embrace what may be the ultimate paradox in teaching: to facilitate learning we must also be willing to facilitate unlearning. May we, as Walt Whitman decrees, 'ordain ourselves loos'd of limits and imaginary lines'.

description: Developing hybrids of guineagrass (Panicum maximum Jacq.) is difficult mainly because its reproduction is by apomixis. Utilizing sexual female plants and facultative apomictic genotypes, the following crosses were developed at the USDA-ARS, Tropical Agriculture Research Station (TARS): GH-101 (Tift SPM 92 χ PI 3622); GH-102 (Tift 49 χ CI AT 604); GH-103 (Tift 49 χ PI 3622); and BPIH-104, a Brachiaria purpurascens χ P. coloratum interspecific hybrid. In a randomized split-plot design with four replications, the four hybrids, common guineagrass, and cultivar Tobiata (a P. maximum introduction), were evaluated in terms of dry matter yield (DMY) and a series of agronomic characters at 4-, 6-, and 8-wk cutting intervals (CI) during the period of one year at the Isabela ARS farm. On the average, the genotypes DM production increased 60% from the 4- to 6-wk CI and 44% from the 6- to the 8-wk CI. Tobiata and GH-104 were the top yielders with over 38 and 39 t/ha/yr, respectively. These yields are significantly higher than those reported in the tropics for common guineagrass and comparable to yields produced by napiergrass (Pennisetum purpureum Schum.).

description: Observational and theoretical evidence suggest that beams of accelerated particles are produced in flaring events of all sizes in the solar atmosphere, from X-class flares to nanoflares. Current models of these types of particles in flaring loops assume an isolated 1D atmosphere. A more realistic environment for modelling accelerated particles can be provided by 3D radiative magnetohydrodynamics codes. Here, we present a simple model for particle acceleration and propagation in the context of a 3D simulation of the quiet solar atmosphere, spanning from the convection zone to the corona. We then examine the additional transport of energy introduced by the particle beams. The locations of particle acceleration associated with magnetic reconnection were identified by detecting changes in magnetic topology. At each location, the parameters of the accelerated particle distribution were estimated from local conditions. The particle distributions were then propagated along the magnetic field, and the energy deposition due to Coulomb collisions with the ambient plasma was computed. We find that particle beams originate in extended acceleration regions that are distributed across the corona. Upon reaching the transition region, they converge and produce strands of intense heating that penetrate the chromosphere. Within these strands, beam heating consistently dominates conductive heating below the bottom of the transition region. This indicates that particle beams qualitatively alter the energy transport even outside of active regions.

description: Two of the most important perennial forage species of the genus Arachis (A. glabrata Benth . and A. pintoj Krap. & Greg) have been evaluated by TARS in preliminary trials. Desirable qualities of these forage legumes are (1) high biomass of excellent quality, (2) insect resistance and low disease susceptibility, (3) drought tolerance, and (4) long-term persistence. A. Glabrata is propagated by rhizome and A. pintoj by seed or stolon. Two new A. glabrata cultivars released by the University of Florida, "Arblick" and "Ecoturf', were among those evaluated. Rate of establishment using different management techniques and dry matter yield were determined. A. glabrata accessions 17097 and 17033 had 90% ground cover after 120 days on a Mollisol at the Fortuna Substation of the University of Puerto Rico (UPR). These accession 17097 has the ability to produce 25,000 and 21,000 Kg/ha/yr at the 6-and 12-wk CI. These yields, plus its high crude protein concentration (19 and 16% at the two CI), make it an ideal forage legume for use in animal-feeling systems in the tropics.

description: We construct Euclidean random fields $X$ over $\R^d$, by convoluting generalized white noise $F$ with some integral kernels $G$, as $X=G* F$. We study properties of Schwinger (or moment) functions of $X$. In particular, we give a general equivalent formulation of the cluster property in terms of truncated Schwinger functions which we then apply to the above fields. We present a partial negative result on the reflection positivity of convoluted generalized white noise. Furthermore, by representing the kernels $G_\a$ of the pseudo--differential operators $(-\D + m^2_0)^{-α}$ for $α\in (0,1)$ and $m_0>0$ as Laplace transforms we perform the analytic continuation of the (truncated) Schwinger functions of $X=G_α* F$, obtaining the corresponding (truncated) Wightman distributions on Minkowski space which satisfy the relativistic postulates on invariance, spectral property, locality and cluster property. Finally we give some remarks on scattering theory for these models.

description: In models where the gravitino is the lightest supersymmetric particle (LSP), the next-to-lightest supersymmetric particle (NLSP) is long-lived. We consider an important charged NLSP candidate, the scalar tau $\tildeτ$. Slow charged NLSPs may be produced at future colliders and they may be stopped in a massive stopper which simultaneously serves as a detector for the NLSP and its decay products. We found the number of events at a 1 kton to O(10) kton detector could be significant enough to study the NLSP decays with lifetime shorter than $10^{10}$ sec at the LHC. The performance of existing 1 kton detectors may be good enough to do such studies at the LHC, if they can be placed close to the ATLAS/CMS detectors. At a future $e^- e^-$ collider, scalar electrons $\tilde{e}^-$s are copiously produced. Slow NLSPs may be produced from the $\tilde{e}^-$ decay. The number of stopped NLSPs at a future linear collider could be large enough to study rare decay modes of the NLSP.

Ziel der Arbeit ist es, einen Prototypen eines Feedbackgerätes für Armprothesen bereitzustellen und diesen zu validieren. Im ersten Teil werden die Grundlagen, auf denen diese Arbeit aufbaut, dargelegt und die Geschichte des Feedbacks und der Prothetik kurz umrissen. Im zweiten Teil wurden Konzepte von mechanischen Feedbackgeräten und daraus vier unterschiedlich wirkende Prototypen entwickelt. Die aus der Entwicklung erhaltenen Prototypen wurden, nach deren Herstellung, vier unterschiedlichen Tests zu Grunde gelegt. Die Tests erfassten in Versuchen mit neun bzw. zehn Probanden die subjektive Empfindung der Reize durch die Probanden, die Wahrnehmung der durch die Prototypen erzeugten Reize und eine Reproduktion von aufgebrachten Mustern eines möglichen Prothesenverhaltens. Die Ergebnisse der Versuche ergaben eine gute Erkennung der Reize aller Prototypen und lieferten bei den Probanden eine hohe Erkennungsrate der Drehrichtung und der Lokalisierbarkeit der von den Prototypen erzeugten Reize. Abschließend konnte noch gezeigt werden, dass komplexe Reizmuster und Abfolgen von simulierten Prothesenbewegungen mit hoher Übereinstimmung erkannt und an einem Versuchsaufbau wiedergegeben werden konnten.
description: Sensory feedback of stimuli to prosthesis users is an interesting topic in existing prostheses and the development of newer prostheses as extension to approach the natural functions of a human limb. Aim of this study is to provide a prototype of a feedback device for prosthetic arms and validate this. In the first part the theoretical background of this work and the history of feedback and prosthetics are briefly outlined. In the second part concepts of mechanical feedback devices and from four different acting prototypes were developed. The prototypes obtained from the development were, after their production, basis for four different tests. The tests detected in experiments with nine and ten subjects the subjective perception of stimuli by the test subjects, the perception of stimuli generated by the prototype and a reproduction of the applied patterns of possible prosthetic behavior. The results of the experiments showed a good recognition of stimuli of all prototypes and delivered a high recognition rate of rotation direction and the localization of the stimuli generated by the prototype. Finally, it has been shown that complex stimulus patterns and sequences of simulated prosthetic movements could be detected with high compliance and could be reproduced on an experimental setup.

description: Due to recent advances in scanning-probe technology, the electronic structure of individual molecules can now also be investigated if they are immobilized by adsorption on non-conductive substrates. As a consequence, different molecular charge-states are now experimentally accessible. Thus motivated, we investigate as an experimentally relevant example the electronic and structural properties of a NaCl(001) surface with and without pentacene adsorbed (neutral and charged) by employing density functional theory. We estimate the polaronic reorganization energy to be $E_\text{reorg} \simeq 0.8-1.0$ eV, consistent with experimental results obtained for molecules of similar size. To account for environmental effects on this estimate, different models for charge screening are compared. Finally, we calculate the density profile of one of the frontier orbitals for different occupation and confirm the experimentally observed localization of the charge density upon relaxation of the substrate from ab-initio calculations.

The present paper provides an empirical analysis of bank credit rationing. First, the author verifies the existence of rationing and the forms in which it is practiced, that is, distinguishing between dynamic rationing and equilibrium rationing. Then, an evaluation of the intensity of rationing and its evolution over time is provided. Finally, the types of customers that are, or have been, affected by rationing is determined. JEL: G21

description: The research presents a voice conversion model using coefficient mapping and neural network. Most previous works on parametric speech synthesis did not account for losses in spectral details causing over smoothing and invariably, an appreciable deviation of the converted speech from the targeted speaker. An improved model that uses both linear predictive coding (LPC) and line spectral frequency (LSF) coefficients to parametrize the source speech signal was developed in this work to reveal the effect of over-smoothing. Non-linear mapping ability of neural network was employed in mapping the source speech vectors into the acoustic vector space of the target. Training LPC coefficients with neural network yielded a poor result due to the instability of the LPC filter poles. The LPC coefficients were converted to line spectral frequency coefficients before been trained with a 3-layer neural network. The algorithm was tested with noisy data with the result evaluated using Mel-Cepstral Distance measurement. Cepstral distance evaluation shows a 35.7 percent reduction in the spectral distance between the target and the converted speech.

description: E ' opinione condivisa all'unanimità che il debito pubblico in Italia ha raggiunto un livello insostenibile . Inoltre , è opinione molto diffusa che la pressione fiscale in Italia deve rimanere costante . Il precedente parere è quasi diventata una cliché , mentre il secondo un vincolo politica . L'articolo distingue le gravi argomenti sui quali queste opinioni sono basate da quelli che sono false . L'analisi delle ragioni di insostenibilità porta l'autore a sostenere che esso è ancora maggiore se il vincolo politico sull'aumento del carico fiscale è accettata . Alcune raccomandazioni sono previste per quanto riguarda le condizioni necessarie per ridurre la crescita del debito a un tasso che non sia superiore alla crescita del PIL. L'autore conclude che la scelta l'Italia si trova di fronte non è semplicemente tra il costo di un relativamente rapido riadattamento e la ricerca di alternative che sono impossibili senza costi . Piuttosto , la scelta è tra minori costi da tenere a breve termine o costi più elevati se prolungata It is a unanimously shared opinion that Italy's public debt has reached an unsustainable level. Furthermore, it is a very widespread opinion that the tax burden in Italy must remain constant. The former opinion has almost come to be a cliché, while the latter a political constraint. The article distinguishes the serious arguments on which these opinions are based from those that are spurious. An analysis of the reasons for unsustainability leads the author to argue that it is even greater if the political constraint on raising the tax burden is accepted. Some recommendations are provided regarding the conditions necessary to reduce the growth of debt at a rate that is not higher than the growth of GDP. The author concludes that the choice Italy faces is not simply between the cost of a relatively rapid readjustment and the search for alternatives that are impossible without costs. Rather, the choice is between smaller costs to bear in the shorter term or higher costs if protracted. JEL: H63, H21

description: Der seit mehreren Generationen wachsende Tischlereibetrieb der Familie Rüscher stößt an seine Grenzen, denn die in die Jahre gekommene Bausubstanz kann einen wirtschaftlichen Produktionsablauf nicht mehr gewährleisten. Mit der fortschreitenden Industrialisierung des Handwerks sind heute längst nicht nur mehr kleine Hand - oder Standmaschinen im Einsatz. Während früher leerstehende Ställe und Garagen zu Werkstätten umfunktioniert werden konnten, sind die Anforderungen an einen 'Werkraum' heute sehr vielschichtig. Neben strengen Auflagen an Brandschutz, Unfallverhütung und Hygiene gilt es vor allem, den immer komplexer werdenden Produktionsabläufen ihren notwendigen Raum zu geben. Der Neubau der Tischlerei Rüscher in der kleinen bregenzerwälder Gemeinde Schnepfau soll diese Anforderungen unter einem Dach vereinen und über weitere Generationen hinaus eine hochqualitative und zeitgemäße Arbeitsstätte ohne räumliche Barrieren sein. Dies erfordert nicht nur eine akribische Planung des Gebäudes selber, sondern auch eine sehr sorgfältige Integration des Volumens in die kleinmaßstäbliche Bebauungsstruktur der Gemeinde. Das Raumprogramm wird neben Räumen für Lagerung, Produktion, Administration und Bereichen für Mitarbeiter durch einen Ausstellungsraum erweitert, der als Bühne für ausgewählte Möbelstücke dient und von weitem erkennbar als Kommunikator nach außen dient.
description: For several generations the Ruescher family carpentry has been growing and its current building structure can no longer support an economic production process. With the progressive industrialization of the crafts, new technology has been integrated and it is no longer just hand and table machines that are in use. In earlier times empty stables and garages were used as workspaces, but with todays multifaceted requirements of a workstation, this is no longer possible. Parallel to strict regulations regarding fire safety, accident prevention and hygiene, the ever developing production processes need suitable space. The construction of the Ruescher carpentry in the small village of Schnepfau should fulfill all its requirements under one roof and function as a high quality, contemporary workplace that is adaptable for future generations. This does not only demand meticulous planning of the building itself, but also has to blend into the architectural language of the surrounding area. Besides for storage , production, administration and recreational rooms, the new construction will include an exhibition suite, which will display carefully chosen workpieces to the general public.
Pre-partum behaviour and intake identify dairy cows at risk for post-partum metritis

description: Metritis is a disease of particular concern after calving due to its negative effects on the reproductive performance of dairy cows. Previous work has shown that cows at risk for post-partum metritis have lower feeding times in the days before calving. However, the authors did not monitor individual dry matter intake (DMI), a measure that may be more sensitive in the detection of illness, or other behavioural or intake measures such as drinking or social behaviour that may prove to be useful predictors of disease. The objective of this study was to determine which pre-partum measures are most sensitive in predicting post-partum metritis. Feeding and drinking measures were collected from 101 Holstein dairy cows from 2 wks before until 3 wks after calving using an electronic monitoring system. Social behaviour at the feed bunk was assessed from video recordings. Metritis severity was diagnosed based on daily rectal body temperature and vaginal discharge that was assessed every 3 d after calving until d+21. In this study, 12% of cows were classified as severely metritic and 27% as mildly metritic. Feeding time and DMI were best able to identify cows at risk for metritis. Cows that developed severe metritis spent less time feeding and consumed less feed relative to healthy cows 2 wks before any observation of clinical signs of infection. For every 10- min decrease in average daily feeding time during the wk before calving the odds of severe metritis increased by 1.72, and for every 1 kg decrease in DMI during this period, cows were nearly 3 times more likely to be diagnosed with this disorder. During the wk before calving cows that were later diagnosed with severe metritis had lower DMI and feeding times during the hours following fresh feed delivery. During this period these cows also engaged in fewer aggressive interactions at the feed bins compared to cows that remained healthy. This research is the first to show that social behaviour may play an important role in transition cow health. Further research is required to determine how management practices should be changed to reduce illness in transition dairy cows.

description: Il lavoro sostiene che dagli anni settanta l'economia internazionale ha oscillato tra due tipi di strutture di flusso , si riflette nella ripresa e l'altra nel downswing . In entrambi i casi , l'economia internazionale ha sofferto , anche se in modi diversi , dalla scomparsa di alcune delle " valvole di sicurezza " che avevano consentito nel corso degli anni Cinquanta e Sessanta per incongruenze ex ante da risolvere senza ostacolare la generazione e trasmissione di uscita e la crescita del reddito .L'autore mette in evidenza somiglianze nella struttura del flusso e nei problemi di aggiustamento corrispondenti ricorrenti nel ciclo . L'autore si concentra sulle relazioni che hanno influenzato la parte industriale del mondo , e li esamina in un approccio sistemico che copre l'intera rete di connessioni mondiali The work argues that since the seventies the international economy has oscillated between two kinds of flow structures, one reflected in the upswing and the other in the downswing. In both cases, the international economy suffered, although in different ways, from the disappearance of some of the “safety valves” that had made it possible during the fifties and sixties for ex ante incongruities to be resolved without impeding the generation and transmission of output and income growth. Dealing with the stylised facts, the author brings out similarities in flow structures and in the corresponding adjustment problems recurring in the cycle. The author concentrates on relationships which have influenced the industrial part of the world, and examines them in a systemic approach covering the entire network of world connections.

description: Twirl operations, which convert impure singlet states into Werner states, play an important role in many schemes for entanglement purification. In this paper we describe strategies for implementing twirl operations, with an emphasis on methods suitable for ensemble quantum information processors such as nuclear magnetic resonance (NMR) quantum computers. We implement our twirl operation on a general two-spin mixed state using liquid state NMR techniques, demonstrating that we can obtain the singlet Werner state with high fidelity.
