Higher Order Two Step Mechanisms in Nucleon Antinucleon Annihilation and the OZI Rule

We evaluate three meson doorway mechanisms for nucleon-antinucleon annihilation at rest for the first time. Detailed results are presented for the final state phi pi0 originating from the 3S1 initial state and for the phi rho channel originating from 1S0. The results presented also include the improved contributions from two meson doorway states and from the tree diagrams. For all the channels considered a consistent explanation of large and small OZI violations emerges.Comment: 18 pages, 2 PostScript figures, will be published in Eur. Phys. J.

Erarbeitung eines Kommunikationskonzeptes für Premotion Andermatt

In Andermatt entsteht zurzeit das grösste Tourismusresort der Schweiz. Die Marketing- und Eventagentur Premotion, mit Hauptsitz in Luzern, sieht in dieser Destination sehr viel Potenzial und hat aus diesem Grund vor zwei Jahren einen zweiten Firmensitz in Andermatt eröffnet. In dieser Arbeit wird ein Kommunikationskonzept für Premotion Andermatt erar-beitet. Um die aktuelle Marktsituation in Andermatt aufzuzeigen, wurden qualitative Inter-views durchgeführt und in der Sekundärliteratur zu den Bedürfnissen und Trends der Event-branche recherchiert. Die oberste Priorität für Premotion Andermatt ist es, ihren Bekanntheitsgrad zu erhöhen. Dafür sollen besonders die Dialoggruppen Marketing-/Personal- und Eventverantwortliche in mittleren bis grossen Firmen, Geschäftsführer in kleinen bis mittleren Betrieben, sowie be-stehende Kunden angesprochen werden. Da sich das Tourismusresort Andermatt noch in der Entwicklung befindet, sieht die erarbeitete Strategie vor, dass in einer ersten Phase die Kun-den die Vision und die Entstehung des Tourismusresorts persönlich miterleben sollen. Sobald sich die Destination als eine der Top-Destinationen der Schweiz etabliert haben wird, wird das Verkaufsargument nicht mehr die Vision, sondern die Destination Andermatt an sich sein. Die Nachfrage nach Events wird bis dahin nochmals deutlich ansteigen und die Rolle als Eventdienstleister ist dann für Premotion Andermatt erfolgsversprechend. Um die festgesetzten Kommunikationsziele zu erreichen und somit die Kommunikation für Premotion Andermatt zu optimieren, sollen verschiedene Massnahmen umgesetzt wer-den. Unter den vorgeschlagenen Massnahmen nimmt die Online-Kommunikation einen ho-hen Stellenwert ein. Mittels Suchmaschinenoptimierung und Google AdWords sollen poten-zielle Kunden im Internet auf Premotion Andermatt aufmerksam gemacht werden. Eine wei-tere wichtige Massnahme ist die interne Kommunikation. Alle geplanten Massnahmen wer-den in einer Übersicht dargestellt, priorisiert und zeitlich strukturiert. Abschliessend werden Handlungsempfehlungen gegeben und erläutert, wie die Kommunikationsmassnahmen für Premotion Andermatt optimal in die Gesamtkommunikation eingebunden werden können

Sedimentology-based reconstructions of paleoclimate changes in the Central Andes in response to the uplift of the Andes, Arica region between 19 and 21°S latitude, northern Chile

We focus on the sedimentological record of the Middle Miocene to modern deposits in the Andes of northern Chile between 19 and 21°S. These sediments, deposited at the Western Escarpment of the Central Depression, indicate successively more moisture on the western margin of the Altiplano and the Western Cordillera where the sources are. At the Pacific Coast, 20-Ma-old exposure ages and salic gypsisols reflect an existing and ongoing hyperarid climate. We interpret the increased divergence of climates between the Coast and the Altiplano as consequence of the Andean rise to elevations higher than approximately 2,500m a.s.l., when the topography of the Altiplano was sufficiently high and areally extensive to attract Atlantic moisture. Accordingly, the inferred general increase in run-off was closely coupled with the uplift of the Andes if the steady rise model applies. In case that the rapid rise model for Andean uplift is correct, the inferred changes in sediment transport would have occurred independently of uplift, requiring an alternative, yet unknown drive

Clinical Impact of a Novel Interprofessional Dental and Pharmacy Student Tobacco Cessation Education Program on Dental Patients

Objectives: • To compare the difference between IPE care and standard care (SC) groups regarding dental patients\u27 perceptions of knowledge gained about tobacco cessation, intentions to quit tobacco use, and quit attempts at follow-up. • To evaluate perceptions of IPE care. Background: Based on the link between tobacco use and oral health and the frequent contact between dental providers and patients, the dental clinic is an ideal setting to address tobacco use.1 • Many dentists feel unprepared providing tobacco cessation education, particularly pharmacologic treatment options.1-3 • Pharmacists promote safe and effective pharmacologic treatment options for tobacco dependence and patients’ perceptions toward pharmacist-provided tobacco cessation education have been positive.4-6 • A novel interprofessional education (IPE) program involving dental and pharmacy students may address the need for tobacco cessation education in the dental clinic setting

Evaluating the Impact of an Interprofessional Practice Experience Involving Pharmacy and Dental Students on Medication Histories within an Urban Academic Dental Admissions Clinic

Primary Objective: To compare interprofessional (IP) care versus standard care on medication history clarifications in dental patients. Secondary Objectives: To assess the clinical significance of these clarifications with regards to the potential impact on dental treatment plans. To describe the interventions provided by IP care to clarify discrepancies and/or resolve medication-related problems

Sustainability Indicators Past and Present: What Next?

This paper discusses the current state of thought amongst the Sustainability Indicator (SI) community, what has been achieved and where we are succeeding and failing. Recent years have witnessed the rise of “alternative facts” and “fake news” and this paper discusses how SIs fit into this maelstrom, especially as they are themselves designed to encapsulate complexity into condensed signals and it has long been known that SIs can be selectively used to support polarized sides of a debate. This paper draws from chapters in a new edited volume, the “Routledge Handbook of Sustainability Indicators and Indices”, edited by the authors. The book has 34 chapters written by a total of 59 SI experts from a wide range of backgrounds, and attempts to provide a picture of the past and present, strengths and weaknesses of SI development today. This paper is an “analysis of those analyses”—a mindful reflection on reflection, and an assessment of the malign and benign forces at work in 2018 within the SI arena. Finally, we seek to identify where SIs may be going over the coming, unpredictable years

Beef production from feedstuffs conserved using new technologies to reduce negative environmental impacts

End of project reportMost (ca. 86%) Irish farms make some silage. Besides directly providing feed for livestock, the provision of grass silage within integrated grassland systems makes an important positive contribution to effective grazing management and improved forage utilisation by grazing animals, and to effective feed budgeting by farmers. It can also contribute to maintaining the content of desirable species in pastures, and to livestock not succumbing to parasites at sensitive times of the year. Furthermore, the optimal recycling of nutrients collected from housed livestock can often be best achieved by spreading the manures on the land used for producing the conserved feed. On most Irish farms, grass silage will remain the main conserved forage for feeding to livestock during winter for the foreseeable future. However, on some farms high yields of whole-crop (i.e. grain + straw) cereals such as wheat, barley and triticale, and of forage maize, will be an alternative option provided that losses during harvesting, storage and feedout are minimised and that input costs are restrained. These alternative forages have the potential to reliably support high levels of animal performance while avoiding the production of effluent. Their production and use however will need to advantageously integrate into ruminant production systems. A range of technologies can be employed for crop production and conservation, and for beef production, and the optimal options need to be identified. Beef cattle being finished indoors are offered concentrate feedstuffs at rates that range from modest inputs through to ad libitum access. Such concentrates frequently contain high levels of cereals such as barley or wheat. These cereals are generally between 14% to 18% moisture content and tend to be rolled shortly before being included in coarse rations or are more finely processed prior to pelleting. Farmers thinking of using ‘high-moisture grain’ techniques for preserving and processing cereal grains destined for feeding to beef cattle need to know how the yield, conservation efficiency and feeding value of such grains compares with grains conserved using more conventional techniques. European Union policy strongly encourages a sustainable and multifunctional agriculture. Therefore, in addition to providing European consumers with quality food produced within approved systems, agriculture must also contribute positively to the conservation of natural resources and the upkeep of the rural landscape. Plastics are widely used in agriculture and their post-use fate on farms must not harm the environment - they must be managed to support the enduring sustainability of farming systems. There is an absence of information on the efficacy of some new options for covering and sealing silage with plastic sheeting and tyres, and an absence of an inventory of the use, re-use and post-use fate of plastic film on farms. Irish cattle farmers operate a large number of beef production systems, half of which use dairy bred calves. In the current, continuously changing production and market conditions, new beef systems must be considered. A computer package is required that will allow the rapid, repeatable simulation and assessment of alternate beef production systems using appropriate, standardised procedures. There is thus a need to construct, evaluate and utilise computer models of components of beef production systems and to develop mathematical relationships to link system components into a network that would support their integration into an optimal system model. This will provide a framework to integrate physical and financial on-farm conditions with models for estimating feed supply and animal growth patterns. Cash flow and profit/loss results will be developed. This will help identify optimal systems, indicate the cause of failure of imperfect systems and identify areas where applied research data are currently lacking, or more basic research is required
