Effect of an electric field on an intermittent granular flow
Granular gravity driven flows of glass beads have been observed in a silo
with a flat bottom. A DC high electric field has been applied perpendicularly
to the silo to tune the cohesion. The outlet mass flow has been measured. An
image subtraction technique has been applied to visualize the flow geometry and
a spatiotemporal analysis of the flow dynamics has been performed. The outlet
mass flow is independent of voltage, but a transition from funnel flow to
rathole flow is observed. This transition is of probabilistic nature and an
intermediate situation exists between the funnel and the rathole situations. At
a given voltage, two kinds of flow dynamics can occur : a continuous flow or an
intermittent flow. The electric field increases the probability to observe an
intermittent flow.Comment: Accepted for publication in PRE on Apr 9, 201

Spring 1956
This year the newly organized Turf Management Club has undertaken the publication of a booklet featuring various aspects of turf work. Through this we are attempting to present material that will be of interest to those who are familiar with the Massachusetts Turf Schools. At the same time we hope that it may have some educational value by presenting the view of both of those of us on the job and others engaged in research and promotion and selling.
The publication will include information about the current years winter school and turf conference, articles about some of the professors here at the University who are responsible for the course work, reports about activities and honors earned by the Stockbridge Turf Majors while on campus; and reports on research in fine turf conducted here at the University of Massachusetts. There will also be articles written by men connected with turf work such as yourselves and articles written by staff members at the University.
The main objective of this publication is to form a bond of common interest and friendship between the alumni and other friends of our turf schools. Those of us who graduate this year are looking forward to getting the news from the university in years to come. We hope you feel the same
Erarbeitung betriebsindividueller Handlungsempfehlungen zur Verbesserung der Euter- und Stoffwechselgesundheit im Rahmen einer interdisziplinÀren Interventionsstudie
Kernziel des im Rahmen des Bundesprogramms Ăkologischer Landbau initiierten Forschungsvorhabens âGesundheit und LeistungsfĂ€higkeit von MilchkĂŒhen im ökologischen Landbau interdisziplinĂ€r betrachtetâ (FKZ 07OE012 - 07OE022) ist
- neben der AbschĂ€tzung des Risikos fĂŒr Stoffwechselstörungen und Eutererkrankungen - die Entwicklung eines praxistauglichen, prĂ€ventiv orientierten Tiergesundheitsmanagements fĂŒr die Praxis der ökologischen Milchviehhaltung. Basierend auf einer Interventionsstudie auf 106 reprĂ€sentativ ausgewĂ€hlten Milchviehbetrieben soll dieses Managementkonzept in einer zweijĂ€hrigen Praxisphase validiert und auf seine Praxistauglichkeit ĂŒberprĂŒft werden. Als Grundlage fĂŒr die Identifikation einzelbetrieblicher InterventionsmaĂnahmen dienen zentrale Indikatoren der Euter- und Stoffwechselgesundheit, deren Abgleich mit im Vorfeld definierten ZielgröĂen sowie Informationen zur Haltungsumwelt und zum Herdenmanagement. Das entwickelte Konzept soll eine einzelbetriebliche EinschĂ€tzung des Gesundheitsstatus der Milchviehherde bezĂŒglich der Euter- und Stoffwechselgesundheit ermöglichen, auf deren Basis Handlungsempfehlungen zur nachhaltigen Verbesserung der Milchviehgesundheit abgeleitet werden können. Die Projektbetriebe setzten zwei Drittel der empfohlenen MaĂnahmen um; eine abschlieĂende EffektivitĂ€tskontrolle in Bezug auf die Verbesserung der Euter- und Stoffwechselgesundheit auf den Betrieben auf Basis der Daten des letzten Projektjahres steht noch aus
Characteristics of transposable element exonization within human and mouse
Insertion of transposed elements within mammalian genes is thought to be an
important contributor to mammalian evolution and speciation. Insertion of
transposed elements into introns can lead to their activation as alternatively
spliced cassette exons, an event called exonization. Elucidation of the
evolutionary constraints that have shaped fixation of transposed elements
within human and mouse protein coding genes and subsequent exonization is
important for understanding of how the exonization process has affected
transcriptome and proteome complexities. Here we show that exonization of
transposed elements is biased towards the beginning of the coding sequence in
both human and mouse genes. Analysis of single nucleotide polymorphisms (SNPs)
revealed that exonization of transposed elements can be population-specific,
implying that exonizations may enhance divergence and lead to speciation. SNP
density analysis revealed differences between Alu and other transposed
elements. Finally, we identified cases of primate-specific Alu elements that
depend on RNA editing for their exonization. These results shed light on TE
fixation and the exonization process within human and mouse genes.Comment: 11 pages, 4 figure
Electronic Structure and Valence Band Spectra of Bi4Ti3O12
The x-ray photoelectron valence band spectrum and x-ray emission valence-band
spectra (Ti K _beta_5, Ti L_alpha, O K_alpha) of Bi4Ti3O12 are presented
(analyzed in the common energy scale) and interpreted on the basis of a
band-structure calculation for an idealized I4/mmm structure of this material.Comment: 6 pages + 7 PostScript figures, RevTex3.0, to be published in

Performing thinking in action: the meletÄ of live coding
Within this article, live coding is conceived as a meletÄ, an Ancient Greek term used to describe a meditative thought experiment or exercise in thought, especially understood as a preparatory practice supporting other forms of critical â even ethical â action. Underpinned by the principle of performing its thinking through 'showing the screen', live coding involves 'making visible' the process of its own unfolding through the public sharing of live decision-making within improvisatory performance practice. Live coding can also be conceived as the performing of 'thinking-in-action', a live and embodied navigation of various critical thresholds, affordances and restraints, where its thinking-knowing cannot be easily transmitted nor is it strictly a latent knowledge or 'know how' activated through action. Live coding involves the live negotiation between receptivity and spontaneity, between the embodied and intuitive, between an immersive flow experience and split-attention, between human and machine, the known and not yet known. Moreover, in performing 'thinking-in-action', live coding emerges as an experimental site for reflecting on different perceptions and possibilities of temporal experience within live performance: for attending to the threshold between the live and mediated, between present and future-present, proposing even a quality of atemporality or aliveness
Seasonality in depressive and anxiety symptoms among primary care patients and in patients with depressive and anxiety disorders; results from the Netherlands Study of Depression and Anxiety
<p>Abstract</p> <p>Background</p> <p>Little is known about seasonality of specific depressive symptoms and anxiety symptoms in different patient populations. This study aims to assess seasonal variation of depressive and anxiety symptoms in a primary care population and across participants who were classified in diagnostic groups 1) healthy controls 2) patients with a major depressive disorder, 3) patients with any anxiety disorder and 4) patients with a major depression and any anxiety disorder.</p> <p>Methods</p> <p>Data were used from the Netherlands Study of Depression and Anxiety (NESDA). First, in 5549 patients from the NESDA primary care recruitment population the Kessler-10 screening questionnaire was used and data were analyzed across season in a multilevel linear model. Second, in 1090 subjects classified into four groups according to psychiatric status according to the Composite International Diagnostic Interview, overall depressive symptoms and atypical versus melancholic features were assessed with the Inventory of Depressive Symptoms. Anxiety and fear were assessed with the Beck Anxiety Inventory and the Fear questionnaire. Symptom levels across season were analyzed in a linear regression model.</p> <p>Results</p> <p>In the primary care population the severity of depressive and anxiety symptoms did not show a seasonal pattern. In the diagnostic groups healthy controls and patients with any anxiety disorder, but not patients with a major depressive disorder, showed a small rise in depressive symptoms in winter. Atypical and melancholic symptoms were both elevated in winter. No seasonal pattern for anxiety symptoms was found. There was a small gender related seasonal effect for fear symptoms.</p> <p>Conclusions</p> <p>Seasonal differences in severity or type of depressive and anxiety symptoms, as measured with a general screening instrument and symptom questionnaires, were absent or small in effect size in a primary care population and in patient populations with a major depressive disorder and anxiety disorders.</p
