From Sheikh to Terrorist? Arab Characters in American Film
Mita Banerjee,Günther Sommerschuh
American Studies Journal , 2008,
Abstract: The following text provides a brief discussion on how to integrate visual materials such as the film The Wind and the Lion (1975) in the EFL classroom when discussing the use of stereotypes in Hollywood productions especially in regards to Arab culture. The ideas were gathered in a workshop during the Teacher Academy 2005 and summarized for this publication.
The Flight of Albatross—How to Transform It into Aerodynamic Engineering?  [PDF]
Günther Pfeifhofer, Helmut Tributsch
Engineering (ENG) , 2014, DOI: 10.4236/eng.2014.68045

The flight of albatross (Diomedea exulans) takes advantage of the up-drift which is determined by the product of relative wind velocity and it’s gradient above the sea surface, to power its elegant (dynamic) flight over the ocean. Some of the complicated flight manoeuvres are determined by biological necessities. From its most basic flight manoeuvre a technical aerodynamically scheme can be derived which allows the design of a mechanical technical prototype of a wind generator. It is based on a rotational movement in combination with a skillful time dependent adjustment of the airfoil. Several technical possibilities are discussed and with one of these elaborated in some detail. The technology to be developed could be applied in highly asymmetric air streaming environment around high rise buildings, on mountain ridges and of course, also low above sea level and plains. Mathematical-technical conditions for power gain are discussed. The technology could, in principle, also be deployed to exploit velocity gradients in river water environment. The engineering challenges are significant and the presented work is just a blueprint for tasks to be accomplished.

Service Provision in Knowledge-Based Industries – A Global Study on the  [PDF]
Günther Schuh, Wolfgang Boos, Fabian Gaus
Journal of Service Science and Management (JSSM) , 2010, DOI: 10.4236/jssm.2010.31017
Abstract: In today’s times, more than ever cost competition and high demands of globalized value-adding chains put strong pressure on small- and medium-sized toolmakers. As an exclusive differentiation in price is not an option, new means for achieving sustainable competitive positions have to be found. A promising approach for differentiation is to enhance the existing range of products by offering customer-specific services within so-called industrial product-service-systems. However, the lack of local presence inhibits the toolmakers’ abilities to deliver these services to their global customers. To address these challenges the European R&D-project TIPSS has the objective to develop suitable methods, techniques and technologies, for toolmakers to improve their local and global performance thus enabling them to offer industrial product-service-systems on a global scale. The basis of the project is a large scale toolmaker and parts producer survey focusing on service provision. The survey identifies the global footprint of toolmakers regarding the provision of tool-related services. Key findings of the survey with respect to designing industrial product-service-systems are presented in this paper.
Self-organizing actin waves that simulate phagocytic cup structures
Günther Gerisch
BMC Biophysics , 2010, DOI: 10.1186/1757-5036-3-7
Abstract: PACS Codes: 87.16.Ln, 87.19.lp, 89.75.FbThis article is an overview of work supported by the Deutsche Forschungsgemeinschaft in the Priority Program "Optical analysis of the structure and dynamics of supramolecular biological complexes". Subject of our studies has been the self-organization of actin into propagating waves. I review published results on the dynamics and molecular composition of these waves and will elaborate on some connotations that are not detailed elsewhere.The starting question we addressed was: how are actin structures organized de novo in cells that have been depleted of polymerized actin? To inhibit actin polymerization, we have used latrunculinA (LatA). In living cells, this scavenger of actin monomers results in the depolymerization of actin filaments at a rate determined by their turnover. The disassembly and re-assembly of actin structures has been monitored in Dictyostelium cells using a GFP- tagged construct (LimEΔ) that proved to be an appropriate label for recording the dynamics of filamentous actin structures in these cells [1]. The actin structures rapidly turn over, resulting in microscopically detectable breakdown of the actin network in the cell cortex within less than 20 seconds after LatA addition [2].The removal of LatA enables the cells to regain normal actin organization and cell motility within less than an hour. Of interest here is the intermediate state of excessive wave formation before normal cell motility will recover. This state is preceded by the formation of mobile actin patches [3]. The burst of patches at the onset of actin polymerization is mostly due to the fact that clathrin-dependent endocytosis requires actin to polymerize in order for vesicles to be budded off. Therefore, many clathrin-coated pits are arrested at the plasma membrane as long as LatA is present. Accordingly, the first actin structures seen within about 5 minutes after removal of the drug are small, clathrin-induced patches. Later on, actin wave
Relative receptor affinity comparisons among inhaled/intranasal corticosteroids: perspectives on clinical relevance
Günther Hochhaus
Respiratory Research , 2008, DOI: 10.1186/1465-9921-9-75
Abstract: A response was formulated to: Valotis A, H?gger P: Human receptor kinetics and lung tissue retention of the enhanced-affinity glucocorticoid fluticasone furoate. Respir Res 2007, 8:54.Relative receptor binding affinities, while often showing significant variability across different laboratories, are a valid parameter when a comparison of the pharmacological activity of various glucocorticoids at the site of action is desired. Unfortunately within this context, scientific literature including the article from Valotis and H?gger, confuse differences in potency (concentration or dose necessary to achieve a certain effect) with differences in efficacy (a quantitative difference in the overall maximum effect, even if all the receptors are occupied). All glucocorticoids will show the same efficacy as long as the selected dose will occupy the same number of receptors.While relative receptor affinities are useful for comparing in vitro potencies of corticosteroids, these data are not representative of physiologic conditions and should not be used as a basis for comparing the presumed effectiveness of compounds in a clinical situation.Topical corticosteroids, such as beclomethasone dipropionate, budesonide, triamcinolone acetonide, flunisolide, ciclesonide, mometasone furoate (MF), fluticasone propionate (FP), and fluticasone furoate (FF) are first-line treatments for upper respiratory allergic conditions such as asthma and seasonal/perennial rhinitis, as they provide local efficacy and, thereby, reduce systemic glucocorticoid exposure [1-4]. In recent literature, comparative relative receptor affinity (RRA) values for glucocorticoid receptors in nasal/lung tissue are increasingly used to differentiate among topical corticosteroids. In many instances, the presentation of RRA data and rank ordering of compounds is accompanied by overt or subtle implications of clinical efficacy ramifications. While RRA has a rightful place in the comparison of in vitro potency of corticostero
Os cidad?os mundiais entre a liberdade e a seguran?a
Günther, Klaus;
Novos Estudos - CEBRAP , 2009, DOI: 10.1590/S0101-33002009000100002
Abstract: the 9/11 attacks triggered the development of a transnational security architecture that interferes profoundly in individual civil liberties, in the basic rights of state citizens as much as in human rights of the world citizens. the article draws this architecture, shows how it dissolves traditional juridical categories that preserve freedom and discusses why today it's accepted the priority of security over freedom.
Terroristas como pessoas no direito?
Jakobs, Günther;
Novos Estudos - CEBRAP , 2009, DOI: 10.1590/S0101-33002009000100003
Abstract: the preemptive punishment of terrorists and the use of harsh interrogation techniques are not within the classical standards of the rule of law. they belong rather to a state of exception. a state committed to all the usually accepted requirements of the rule of law would not be allowed to carry such a war, because it would have the duty to treat its enemies as persons. therefore, it would not be authorized to treat them as a source of danger. nevertheless, these classical standards have been challenged in the last two decades by major institutional changes that are now being discussed both in theoretical as in practical levels.
Selected topics from recent NMR studies of organolithium compounds
Günther, Harald;
Journal of the Brazilian Chemical Society , 1999, DOI: 10.1590/S0103-50531999000400002
Abstract: after a short introduction to nmr spectroscopy of alkali and alkaline earth metals the review concentrates on nmr investigations of organolithium compounds. the isotopic fingerprint method, which rests on deuterium-induced isotope shifts for 6li resonances, is introduced and exemplified with applications from the aggregation behavior of cyclopropyllithium systems and mixed aggregate formation between methyllithium and lithium salts. in the following chapter, one- and two-dimensional pulse experiments, both for homo- and for heteronuclear spin systems are discussed. finally, the structural aspects associated with benzyllithium are outlined and the formation of polylithium systems by lithium reduction of biphenylenes is described.
Mobilidade e affordance como cerne dos Estudos Pessoa-Ambiente
Günther, Hartmut;
Estudos de Psicologia (Natal) , 2003, DOI: 10.1590/S1413-294X2003000200009
Abstract: starting with a reflection on the disciplinary, theoretical, methodological and terminological multiplicity, and using the analogy of the multivariate model of the canonical correlation, the use of the label person-environment studies is justified. this is followed by a discussion of four spatial concepts (personal space, territoriality, crowding and privacy) and their relationship to mobility. after some comments about affordance, it is suggested that the mobility-affordance link constitutes the molecular element of the reciprocal person-physical space relationship at the core of the person-environment studies.
Pesquisa qualitativa versus pesquisa quantitativa: esta é a quest?o?
Günther, Hartmut;
Psicologia: Teoria e Pesquisa , 2006, DOI: 10.1590/S0102-37722006000200010
Abstract: given the lack of dialogue between qualitative and quantitative researchers, this article assumes an "ecumenical" position. the text argues that both perspectives present advantages, disadvantages, positive and negative points, considering that the chosen method must be adequate to the question of a certain research. the paper presents some distinctions between qualitative and quantitative research. next it points out the complexity of qualitative research in terms of its underlying assumptions, as well as data collection, transcription and analysis. next, quality criteria for qualitative research are considered. the paper closes with a discussion of implications for research when choosing qualitative research and/or quantitative research.
