Nutzung und Zusammenspiel der Rechercheinstrumente an der Bibliothek der Evangelischen Hochschule Nürnberg
Get PDFDiese Bachelorarbeit beschäftigt sich mit der Nutzung bibliothekarischer Rechercheinstrumente wie OPACs, Datenbanken und Resource Discovery Systemen (RDS). Es wird die Frage beantwortet, wie sich die Recherchesituation an einer kleinen Hochschulbibliothek, nämlich der Bibliothek der Evangelischen Hochschule Nürnberg, aus Nutzersicht darstellt und wie die einzelnen Instrumente wahrgenommen und verwendet werden. Ziel der Arbeit ist es, den Ist-Stand an dieser Bibliothek aufzuzeigen und daraus konkrete Handlungsempfehlungen abzuleiten. Zur Beantwortung der Forschungsfrage wurden mehrere Untersuchungsmethoden kombiniert: eine Online-Nutzerbefragung, eine Mitarbeiterbefragung in Form einer Fokusgruppe sowie eine Erhebung von statistischen Nutzungsdaten. Die Ergebnisse zeigen ein gemischtes Bild. Während die Zufriedenheit mit den verschiedenen Tools insgesamt hoch war, hatten Nutzer mitunter Probleme bei der Auswahl und Bedienung der Tools. Das vorhandene RDS ist noch nicht optimal in die Abläufe der Bibliothek eingebunden. Daher wird der Bibliothek empfohlen, Verbesserungen an der Nutzeroberfläche des RDS vorzunehmen, sowie eine Marketingstrategie dafür umzusetzen und es langfristig zum Hauptrechercheinstrument der Bibliothek auszubauen.This bachelor thesis discusses the use of library research tools such as OPACs, databases and resource discovery systems (RDS). It answers the question of how the research situation at a small university library, the Library of the Lutheran University of Applied Sciences Nuremberg, presents itself from the user's perspective and how the individual tools are perceived and used. The aim is to show the current situation at the library and to derive specific improvement suggestions from the results. To answer the research question, several methods were combined: an online user survey, a staff survey in the form of a focus group and a collection of statistical usage data. The results show a mixed picture. While overall satisfaction with the different tools was high, users sometimes had difficulties in choosing and using the tools. The RDS is not yet fully integrated into the library’s workflows. Therefore, the library is encouraged to make improvements to the user interface of the RDS and to implement a marketing strategy for it, as well as to develop it into the library’s main research tool in the long term
New food approaches to reduce and/or eliminate increased gastric acidity related to gastroesophageal pathologies
No full textObjectives: Gastroesophageal reflux disease (GERD) is very common in industrialized countries, and it is rapidly and significantly increasing, even in developing countries. Unlike reported to date in the scientific literature, in this study aims to assess the ability of reduced-carbohydrate diets and foods enriched with acid pH (lemon and tomato) to quickly and exponentially reduce the symptoms related to conditions such as gastritis and gastroesophageal reflux that are unrelated to Helicobacter pylori.
Methods: Following the administration of an anamnestic test, 130 subjects were selected, including 73 women and 57 men, aged 21 to 67, with a gastritis diagnosis for 92 subjects (including 56 women and 36 men) and reflux gastritis for 38 subjects (17 women and 21 men). Study participants followed 3 dietary treatments in succession. Each treatment lasted two weeks, and treatments were separated by two weeks of washout. The subjects followed a diet, consisting primarily of proteins and fats, that included the exponential reduction of glycides (simple and complex). In addition, the treatment provided for the daily intake of the juice of two lemons and approximately 100 g of fresh orange tomato without seeds eaten either raw or cooked and peeled.
Results: During the treatment and at the end of two weeks of treatment, the subjects reported significant improvements, including an almost total disappearance of symptoms related to the disease in question.
Conclusions: This study shows that a carbohydrate-free diet and/or highly hypoglycidal diet enriched with acid pH foods seems to lead to a decrease in the pH of the gastric contents, thus inhibiting further production of hydrochloric acid with a reduction or disappearance of heartburn symptoms typical of gastroesophageal diseases

No full textThe use of erythropoiesis-stimulating agents is safe and effective in the management of anaemia in myelofibrosis patients treated with ruxolitinib
No full textErythropoiesis-stimulating agents (ESAs) were combined with ruxolitinib in 59 anaemic myelofibrosis patients (93% with Dynamic International Prognostic Scoring System [DIPSS] intermediate-2/high risk; 52·5% transfusion-dependent). Anaemia response (AR) rate was 54% and 76% of patients responded at 5 years. A further 15% displayed minor improvement in anaemia and 78% of patients reduced spleen size. Endogenous erythropoietin levels <125 u/l correlated with a higher AR rate (63% vs. 20%, P = 0·008). No thrombotic events or other toxicities occurred. Overall survival was 62% at 4 years, influenced by DIPSS and transfusion dependency. ESAs seem effective in improving anaemia in ruxruxolitinib-treated myelofibrosis patients

No full textViolenza di genere-stalking-nuove prassi operative
No full textLa vulnerabilità della vittima costituisce una categoria aspecifica che apre un doppio binario all'interno della fase delle indagini preliminari e della
fase dibattimentale, con l'effetto dell'affievolimento della presunzione di non colpevolezza dell'indagato/imputato. Da qui non soltanto le aporie sistematiche, ma anche l'inefficacia di un'azione di contrasto alla violenza di genere che necessita, invece, di una reale politica di prevenzione
Test-particle dynamics in general spherically symmetric black hole spacetimes
No full textTo date, the most precise tests of general relativity have been achieved through pulsar timing, albeit in the weak-field regime. Since pulsars are some of the most precise and stable “clocks” in the Universe, present observational efforts are focused on detecting pulsars in the vicinity of supermassive black holes (most notably in the Galactic Centre), enabling pulsar timing to be used as an extremely precise probe of strong-field gravity. In this paper, a mathematical framework to describe test-particle dynamics in general black-hole spacetimes is presented and subsequently used to study a binary system comprising a pulsar orbiting a black hole. In particular, taking into account the parameterization of a general spherically symmetric black-hole metric, general analytic expressions for both the advance of the periastron and for the orbital period of a massive test particle are derived. Furthermore, these expressions are applied to four representative cases of solutions arising in both general relativity and in alternative theories of gravity. Finally, this framework is applied to the Galactic center S-stars and four distinct pulsar toy models. It is shown that by adopting a fully general-relativistic description of test-particle motion which is independent of any particular theory of gravity, observations of pulsars can help impose better constraints on alternative theories of gravity than is presently possible
