Academic literature on the topic 'Hannah Research Institute'

The discipline of International Relations has long had an uneasy relationship to revolution. Hannah Arendt's remark that the twentieth century has been shaped by wars and revolutions is often quoted, but it is striking how, within the institutionalized research and teaching on International Relations, these two historically formative processes receive differential treatment. Courses, journals, departments and institutes on war are plentiful. Study of war, in its historical, strategic and ethical dimensions, as well as in policy terms, is central to the academic study of IR. Revolutions, by contrast, enjoy a marginal existence. Standard textbooks and theoretical explorations devote little space to them. There is no journal specializing in this question. We have yet to meet the Oliver Cromwell Professor of Revolutionary Studies: there are no invitations to speak at the Thomas Paine International Institute for the Comparative Study of Revolutionary Change.

Work at The Hannah Research Institute has demonstrated the effects of an inhibitory (autocrine) protein, within the whey fraction of milk, on the efficiency of milk secretion and responses to changes in milking frequency. The regulatory mechanism involves both the concentration of the inhibitor and the site of milk storage (relative to its site of action, the secretory tissue). Milk storage characteristics influence responses to a number of management practices, most notably changes in milking frequency (Dewhurst and Knight, 1992; Knight and Dewhurst, 1992). There is, therefore, a need to understand phenotypic sources of variation in the sites of milk storage in order to define standard conditions and procedures for making cistern measurements.

Recently there has been increased interest in the effects of changing the milking frequency of dairy cows because of the possibilities of either increased milking frequency, through the use of robot-milkers or of once-daily milking as a part of a programme of extensification. Archer (1983), reviewing the literature and data from herds monitored by Farm Management Services, found milk yield responses on changing from twice- to thrice-daily milking from -0.14 to +0.49. These differences represent large between-animal differences in responses to thrice-daily milking and there is a need to identify sources of this variation.Milk is stored in the udder in both the cistern and the secretory alveolar tissue itself. Since milk contains a protein which is inhibitory to secretion, storage within the secretory tissue is disadvantageous and reduces the efficiency of secretory tissue. Work at the Hannah Research Institute has shown that the effect of the inhibitor can be overcome by milking more frequently and that the response to thrice-daily milking of goats was greater with animals having smaller cisterns.

This third Special Issue featuring Undergraduate Research offers more compelling examples of study abroad learning. The student articles span several academic disciplines and geographic regions, and together provide us with an understanding of the high-level academic work of which students studying abroad are capable. Each of the three Special Issues that we have published have been well received by education abroad colleagues, faculty, and by those interested in the assessment student learning outcomes. The Frontiers Editorial Board continues to believe that these volumes serve an important purpose in raising the bar for quality education abroad programs by showcasing the very best examples of what our students may achieve. Based on the very positive feedback to these Special Issues, we think that these volumes are achieving this goal. The collaboration with the Forum on Education Abroad in publishing these volumes has been extremely fruitful. The idea for the Undergraduate Research Awards, from which the student papers are generated, began and continues to be nurtured in the work of the Forum on Education Abroad’s Committee on Outcomes Assessment. A full description of the Committee’s work and the award selection process is available on the Forum web site at www.forumea.org. Natalie Mello of Worcester Polytechnic Institute coordinated the Undergraduate Research Awards process and the mentoring of students who presented at the Forum Conference in Austin in March, 2007, and we thank her for her outstanding work. She worked with the faculty selection committee that chose the Award winners and that nominated students who submitted their papers to Frontiers for review. The three winners who presented at the conference were Hannah Arem, Demetri Blanas Hannah Arem, and Jason Nossiter who were all outstanding. Many attendees commented that their presentations were highlights of the conference. This year’s selection process has been overseen by Bernhard Streitwieser of Northwestern University, and we thank him for his excellent work. Bernhard collaborated with Neal Sobania of Pacific Lutheran University to write an exceptional introductory article that discusses the important topic of institutional oversight of and the role of the Institutional Review Board (IRB) in student research conducted abroad. Drawing on the relevant literature, established best practices, and their own experiences in overseeing programs that involve students in conducting research, they offer expert guidance to those of us who are developing and managing education abroad programs that involve student research. I am pleased to announce that at its most recent meeting the Frontiers Editorial Board decided to continue to publish in future volumes the best examples of undergraduate research. The Board will continue to work with the Forum to identify and highlight student research as part of our ongoing collaboration. This project would not have been possible without funding from the IFSA Foundation, which saw the value of featuring research abroad as a way to encourage quality academic achievement in the field. The fact that Frontiers will continue to feature undergraduate student research in future volumes is testimony to the successful outcomes of the IFSA grant. The Frontiers Editorial Board thanks the Foundation for making this possible. As always, we wish to thank our institutional sponsors that continue to support the Frontiers mission.

Tonner E, Beattie J, Flint DJ. Production of insulin-like growth factor binding protein (IGFBP), IGFBP-3 protease, and expression of IGF-I receptors by cells of the sheep immune system. Eur J Endocrinol 1995;132:118–22. ISSN 0804–4643 Single-cell suspensions of sheep thymus cells were cultured in serum-free medium with or without polyclonal activators (phytohaemagglutinin or concanavalin A) and the resultant conditioned medium was assayed for insulin-like growth factor binding protein (IGFBP) activity by binding of [125I]IGF-I, using charcoal to separate free from bound. All cultures produced IGFBP but mitogen stimulation significantly increased IGFBP concentrations, indicating production by lymphoid cells. Conditioned medium also degraded recombinant human [125I]IGFBP-3, suggesting IGFBP-3 protease production within the thymus. This degradation was inhibited by several protease inhibitors (phenylmethylsulphonyl fluoride, aprotinin, N-α-p-tosyl-l-lysine chloromethyl ketone), suggesting the presence of a serine protease. Cell surface [125I]IGF-I binding was demonstrated on cells from thymus, mesenteric lymph node, peripheral blood mononuclear cells and platelets. The [125I]IGF-I binding to platelets could be inhibited by unlabelled peptides, with relative potencies IGF-I > IGF-II ≫ insulin. Scatchard analysis of IGF-I competitive binding revealed a Kd of 266 pmol/l and approximately 40 receptor sites per cell. The high-affinity binding of IGF-I and competition by insulin suggested that the [125I]IGF-I binding was to an IGF-I receptor rather than to a membrane-associated IGFBP, to which insulin does not bind. These data provide further support for the role of the IGF-IGFBP axis in the immune system, particularly in relation to the thymus. Elizabeth Tonner, Hannah Research Institute, Ayr, UK

La synthèse des lipides est une composante importante de l’efficacité et de la qualité des productions animales : - des produits de qualité (viande, lait, oeufs, foie gras, ...) doivent être adaptés aux demandes - parfois contradictoires - des transformateurs et des consommateurs, tant pour leur teneur en lipides que pour la composition de ceux-ci (classes de lipides - cholestérol notamment - et leur composition en acides gras - saturés, polyinsaturés, trans...) qui peuvent modifier leurs caractéristiques technologiques, organoleptiques et diététiques ; - une production efficace suppose d’assurer une production minimale de lipides, en raison de leurs effets positifs sur la qualité, tout en évitant une production excessive qui peut nuire à la qualité et se traduire par un gaspillage énergétique du fait du dépôt ou de la sécrétion de lipides animaux peu valorisables ; - l’adaptation des animaux à des périodes de sous-nutrition physiologique (fin de gestation, début de lactation ...) ou économique (économie d’aliments coûteux) suppose que les réserves lipidiques corporelles mobilisées soient ensuite reconstituées efficacement. Compte tenu de ces enjeux importants pour les différentes filières de production et de la diversité des problématiques de recherche rencontrés pour les différentes espèces domestiques élevées en France, un programme a été mis en place à l’INRA, de 1994 à 1998, à l’initiative de F. Grosclaude et de la Direction Scientifique des Productions Animales. Outre les avancées significatives des méthodes d’étude (notamment utilisation des outils moléculaires), et des connaissances mécanistiques et pratiques qui émergent de cet ensemble de travaux, il faut souligner la dynamique induite par ce programme, avec un développement important de collaborations entre équipes travaillant dans des sites géographiques différents et sur des espèces, des situations physiologiques et des types de produits très variés. Ces travaux ont fait l’objet d’un symposium satellite "Lipogenèse chez les animaux domestiques" dans le cadre des 3èmes journées franco-britanniques de Nutrition (AFN-NS-SNDLF) qui ont eu lieu à Nancy du 30 septembre au 2 octobre 1998. Le présent ouvrage regroupe sept articles d’équipes de l’INRA, qui replacent leurs résultats récents dans le cadre des connaissances disponibles sur la lipogenèse chez huit espèces domestiques (poissons, oiseaux, mammifères monogastriques et ruminants) et onze types de production (viande, oeufs, foie gras, races spécialisées ...). En outre, un texte prospectif de synthèse préparé par R.G. Vernon et al (Hannah Research Institute, Ecosse) compare les animaux domestiques, les rongeurs et l’Homme, et présente les récentes évolutions des recherches sur les mécanismes régulant les voies lipogéniques de différents tissus (muscle, foie, tissu adipeux et glande mammaire).

  The resistance Heils Hanna (HH) was postulated in several tens of 471 previously tested winter barley cultivars. In this paper, new tests on 29 of these cultivars are reported. Thirty-two reference isolates of Blumeria graminis f.sp. hordei held in the pathogen genebank at the Agricultural Research Institute in Kromeriz, Ltd. including a Japanese isolate and five Israeli isolates were used for response tests. However, the resistance HH conferred by the gene Mla8 and herein characterised by reaction type 0 to an old Japanese isolate known as Race I was now postulated only in four cultivars. In the other 25 cultivars another resistance, characterised by reaction type 0 to Race I and also to two Israeli isolates, was detected. In addition to the two mentioned resistances, eight known (Bw, Dr2, Ha, IM9, Ln, Lv, Ra and Sp) resistances were found in the set examined. Lomerit was the only registered cultivar tested here in which the newly detected resistance was present alone, therefore, it is recommended that this resistance be designated Lo.

Abstract In order to maintain viability as a future power-generating technology, concentrating solar power (CSP) must reduce its levelized cost of electricity (LCOE). One component of solving this problem is reducing the cost of the power block while simultaneously increasing the efficiency of the thermodynamic cycle. One disruptive technology that has the promise to accomplish this is supercritical CO2 based power cycles. These cycles are conceptually similar to steam cycles; however, they have substantially smaller turbomachinery at equivalent power while also delivering more efficiency at turbine inlet temperatures of 500–700°C. This paper will summarize the current status of a US Department of Energy project to develop machinery to support a 10 MW sCO2 power cycle. The team of Southwest Research Institute® (SwRI®) and Hanwha Power Systems America, proposed to develop an integrally-geared (IG) compressor-expander (compander) for use in a nominal 10 MW-scale CSP supercritical carbon dioxide (sCO2) plant application. This integrally-geared compander (IGC) comprises multiple pinion shafts interconnected on a single bull gear to create a compact package, and utilizes a low-cost, low-speed driver. In addition, the integrally-geared architecture allows each pinion to operate at different rotational speeds to optimize performance and easily allow for inter-stage cooling and turbine re-heat to further enhance both stage and cycle efficiency. The close integration of all turbomachinery elements into a single integrally-geared (IG) machine creates a design that lends itself to power block modularization, which makes it suitable for waste heat recovery, fossil fuel power plants, and especially CSP applications. As part of the commercialization of this technology, it is necessary to reduce risk by validation testing of key components. In the current work, the focus is developing a test loop to enable safe testing of the main compressor stage across a wide range of operating conditions, and to validate the mechanical integrity of the turbine at full pressure, temperature, and speed. Developing a test loop for sCO2 requires balancing a number of design alternatives that impact cost, lead time, safety, and performance. The current work discusses the design process for the reduced flow test loop for the compander.
