No full textBernhard Ralla, Christoph Holtmann, Gerd GeerlingDepartment of Ophthalmology, University of Düsseldorf, Düsseldorf, GermanyIt is with great interest that we read the publication by Kanellopoulos.1 In this the author shows in a group of 21 patients with 46 months of mean follow-up that the new CXL protocol described, where higher fluence UV light is used with shorter exposure, appears to be a safe, comfortable and effective treatment for stabilizing a progressive keratoconus. This is a very valuable observation. The author also concludes, that collagen cross linking may be a promising adjunct treatment in cases, where a risk of post-LASIK-keratectasia is suspected. LASIK for correction of keratectasia is still controversially discussed. If used as a prophylactic treatment to prevent post-LASIK keratectasia, we would like to point out that the cross linking should be performed preferably after the LASIK procedure because the first will impact various steps of the refractive laser treatment.View original paper by Kanellopoulos
And They Do Speak
No full textSigrun Welke-Holtmann untersucht in ihrer Marburger Dissertation die Gespräche zwischen Frauen und Männern in biblischen Erzähltexten. Mit einer dem Gegenstand angemessenen Kombination aus sprachwissenschaftlichen Analyseinstrumentarien kann die Autorin zeigen, dass die Dialoge zur Konstruktion von Geschlecht beitragen, indem sie Frauen und Männern unterschiedliche Gesprächsstrategien zuschreiben.Sigrun Welke-Holtmann examines the conversations between women and men in biblical narrative texts in her Marburg dissertation. Using a combination of linguistic-analytical instruments appropriate to the subject matter, the author is able to show that dialogues contribute to the construction of gender in that they ascribe different conversational strategies to women and men
Intensivierung von enzymkatalysierten Reaktionen
No full textProcess intensification aims at enabling bridging the gap between fundamental research such as identification of new catalysts and reactions and their implementation in industrial environments. Especially the field of biocatalysis has seen some tremendous improvements and the development of new tools and approaches to bridge this gap. In this contribution we highlight some recent developments as selected case studies.BT/Biocatalysi
Religious diversity, health and healthcare in Canada
No full textBook Chapter: Is religion still a factor in how Canadians understand and experience health? And if yes, how? This chapter will examine religious diversity as it relates to health and healthcare, and will include a consideration of individual experiences of health and well-being, healthcare workers and institutions, and population health. Particular attention will be paid to the ways that religious groups and individuals have played a formative role in building the Canadian healthcare system, as well as hospitals and medical schools. I will document the ways that recent shifts in immigration have raised new issues for healthcare institutions and workers by opening up new debates around the meaning of health, and in particular raising questions around religious healthcare considerations for patients. The chapter concludes with an exploration of current pressing public health issues in Canada as tied to religious diversity and suggestions for further study and research.
Book: This book is intended for advanced undergraduate and graduate students interested in learning about the many ways in which religious diversity is manifest in day-to-day life Canada. Each chapter addresses the challenges and opportunities associated with religious diversity in a different realm of social life from families to churches, from education to health care, and from Muslims to atheists. The contributors present key concepts, relevant statistical data and real-life stories from qualitative data. The content of the book is supplemented by links to online learning resources including videos, websites and photo essays.Peer reviewedbook chapterPublished.spiritual caregivinghealthcare systempublic healthsocial determinants of healthbiomedicinereligious diversityrelations of rulin
Tax Avoidance Using Hybrid Financial Instruments
No full textMultinational companies can use hybrid financial instruments to reduce their tax burden. To achieve such a reduction corporations can exploit the differences in the national tax laws between countries. By evaluating the rules governing demarcation between equity and debt in Germany, France, the UK, the Netherlands, and Luxembourg, the author finds that there are various qualification conflicts which give rise to tax avoidance opportunities in these countries. The implementation of linking rules, a central anti-avoidance mechanism recommended by the OECD, has reduced the revealed tax avoidance opportunities over time. Considering ATAD I and ATAD II, the author analyses former, current, and future tax avoidance opportunities resulting from the use of HFIs
The Oxygen Dilemma: A Severe Challenge for the Application of Monooxygenases?
No full textMonooxygenases are promising catalysts because they in principle enable the organic chemist to perform highly selective oxyfunctionalisation reactions that are otherwise difficult to achieve. For this, monooxygenases require reducing equivalents, to allow reductive activation of molecular oxygen at the enzymes' active sites. However, these reducing equivalents are often delivered to O2 either directly or via a reduced intermediate (uncoupling), yielding hazardous reactive oxygen species and wasting valuable reducing equivalents. The oxygen dilemma arises from monooxygenases' dependency on O2 and the undesired uncoupling reaction. With this contribution we hope to generate a general awareness of the oxygen dilemma and to discuss its nature and some promising solutions.BT/Biocatalysi
On the benefits of explaining herd immunity in vaccine advocacy
No full textMost vaccines protect both the vaccinated individual and the community at large by building up herd immunity. Even though reaching disease-specific herd immunity thresholds is crucial for eliminating or eradicating certain diseases1,2, explanation of this concept remains rare in vaccine advocacy3. An awareness of this social benefit makes vaccination not only an individual but also a social decision. Although knowledge of herd immunity can induce prosocial vaccination in order to protect others, it can also invite free-riding, in which individuals profit from the protection provided by a well-vaccinated society without contributing to herd immunity themselves. This cross-cultural experiment assesses whether people will be more or less likely to be vaccinated when they know more about herd immunity. Results show that in cultures that focus on collective benefits, vaccination willingness is generally higher. Communicating the concept of herd immunity improved willingness to vaccinate, especially in cultures lacking this prosocial cultural background. Prosocial nudges can thus help to close these immunity gaps
Mehr machen mit weniger: Intensivierung von Ganzzell-Bioprozessen
No full textIn chemical process engineering, process intensification (PI) has proven itself as a method that resulted very often in processes with an at least doubled process performance. In recent years, the PI techniques have found more and more applications in biotechnology. Exemplary continuous processes, single-use reactors, electrobiotechnology and hybrid techniques are discussed here.BT/Biocatalysi
