Ultrafast Laser Energy Density and Retinal Absorption Cross-Section Determination by Saturable Absorption Measurements  [PDF]
Alfons Penzkofer, Meike Luck, Tilo Mathes, Peter Hegemann
Journal of Analytical Sciences, Methods and Instrumentation (JASMI) , 2014, DOI: 10.4236/jasmi.2014.41003
Abstract:

Laser pulse nonlinear transmission measurements through saturable absorbers of known absorption parameters allow the measurement of their energy density. On the other hand, nonlinear transmission measurements of laser pulses of known energy density through absorbing media allow their absorption parameter determination. The peak energy density w0P of second harmonic pulses of a mode-locked titanium sapphire laser at wavelength λP = 400 nm is determined by nonlinear energy transmission measurement TE through the dye ADS084BE (1,4-bis(9-ethyl-3-car-bazovinylene)-2-methoxy-5-(2’-ethyl-hexyloxy)-benzene) in tetrahydrofuran. TE(w0P) calibration curves are calculated for

Abstract: Das narrative Interview stellt seit langem ein beliebtes und wichtiges Instrument in der qualitativen Sozialforschung dar. Gabriele LUCIUS-HOENE und Arnulf DEPPERMANN verbinden das narrative Interview in diesem Band mit dem Konzept der narrativen Identit t: Autobiographisches Erz hlen wird so als N hrboden aufgefasst, auf dem Identit tskonstruktionen entstehen und zugleich dargestellt werden. Aufgrund der Fülle und Vielfalt auch neuerer identit tsorientierter Forschungsfragen legen die Autoren in diesem Band ein methodisch reflektiertes und flexibles Auswertungsinstrumentarium vor, das speziell auf solche Fragen ausgerichtet ist. Hierbei beziehen sie Erkenntnisse aus der Erz hl- und Gespr chsforschung sowie der diskursiven Psychologie mit ein. In der Form eines Arbeitsbuchs stellen sie forschungspraktische Fragen und analytische Verfahren zusammen und wenden sich damit in erster Linie an qualitativ Forschende, die sich für Identit tsarbeit in verbaler Interaktion interessieren. In gleichem Ma e nützlich erscheint es aber auch für alle, die eine reflektierte Zusammenstellung von Forschungsergebnissen aus verschiedenen diskursiven Disziplinen suchen. URN: urn:nbn:de:0114-fqs030354 The narrative interview has developed into an important instrument in qualitative research. In this guide book, Gabriele LUCIUS-HOENE and Arnulf DEPPERMANN consistently link the narrative interview to the reconstruction of narrative identities: they regard autobiographical narratives as the soil in which identity constructions are simultaneously developed and presented. Due to the growing number and diversity of research focused on questions of identity and biography in the last few years, the authors compile a set of instruments for the analytical reconstruction of such identity work, which is methodologically reflected as well as flexible in its application. In order to do so, they draw on findings of such fields as narrative psychology, conversation analysis and narrative analysis. Because the book is designed as a study book, it particularly addresses those in qualitative research who are interested in identity work within verbal interaction. Furthermore, it offers a reflective collection of research findings of various discursive disciplines. URN: urn:nbn:de:0114-fqs030354 La entrevista narrativa se ha desarrollado como un instrumento importante en la investigación cualitativa.

Esta es la primera publicación dedicada a la diversidad de carbones en Panamá. Tiene su base en trabajo de campo, estudio de especímenes herborizados y referencias de la literatura. Se incluyen carbones patógenos de plantas cultivadas y silvestres. Las últimas se encontraron sobre todo en zonas rurales. Entre las 24 especies citadas en este estudio, 14 especies son primeros registros para Panamá y una de éstas, Sporisorium ovarium, para América Central. Se encontró Entyloma spilanthis por primera vez en la planta hospedera Acmella papposa var.macrophylla (Asteraceac). Entyloma costaricense y Entyloma ecuadorense son sinónimos de Entyloma compositarum y Entyloma spilanthis respectivamente. "Sphacelotheca" panamensis es una especie dudosa. Se complementan las descripciones de las especies con algunas ilustraciones, una lista de especies y una clave.
Zwischen Skepsis und Ann herung - Island und die Europ ische Union
Meike Stommer
Nordeuropaforum , 2007,
Abstract: Iceland is the only Nordic country which has never applied for membership of the EU. The Icelandic political elite has successfully kept the issue out of the mainstream political discussion. But their actions have not been in line with the political discourse: during the last few decades Iceland has established closer ties to European integration and the EU and, due to decisions made by the political elite, is deeply involved in the processes of European integration. This paper examines the steps which Iceland has taken towards European integration since World War II. The attitudes of the politicalelite, of certain organized groups as well as of the population in general are presented and the reasons for Iceland’s reserved attitude towards the EU are discussed.
Targeting BCL2-Proteins for the Treatment of Solid Tumours

Advances in Medicine , 2014, DOI: 10.1155/2014/943648
Abstract: Due to their central role in the regulation of apoptosis, the antiapoptotic BCL2-proteins are highly promising targets for the development of novel anticancer treatments. To this end, several strategies have been developed to inhibit BCL2, , BCL-w, and MCL1. While early clinical trials in haematological malignancies demonstrated exciting single-agent activity of BCL2-inhibitors, the response in solid tumours was limited, indicating that, in solid tumours, different strategies have to be developed in order to successfully treat patients with BCL2-inhibitors. In this review, the function of the different antiapoptotic BCL2-proteins and their role in solid tumours will be discussed. In addition, a comprehensive analysis of current small molecules targeting these antiapoptotic BCL2-proteins (e.g., ABT-737, ABT-263, ABT-199, TW-37, sabutoclax, obatoclax, and MIM1) will be provided including a discussion of the results of any clinical trials. This analysis will summarise the potential of BCL2-inhibitors for the treatment of solid tumours and will unravel novel approaches to utilise these inhibitors in clinical applications. 1. Mechanisms of Apoptosis Evasion of cell death or apoptosis is a key hallmark of cancer [1]. Generally, cells can die by apoptosis, a form of programmed cell death, or after acute injury by necrosis and cell lysis, which initiates an inflammatory response. Apoptosis was first described as a unique process associated with typical morphological changes by Carl Vogt as early as 1842 and was named apoptosis in 1972 [2]. It is a common property of multicellular organisms and is present in virtually all cell types throughout the body. Apoptosis plays a fundamental role in physiological processes, especially in mammalian development and the immune system [3, 4]. In addition, apoptosis represents a major barrier to cancer cells that must be circumvented. Therefore, many tumours acquire resistance to apoptosis through a variety of strategies. The most commonly occurring loss of a proapoptotic regulator involves the p53 tumour suppressor gene [5]. In addition to the activation of proapoptotic factors, resistance to apoptosis is often due to upregulation of antiapoptotic factors. Thus, a number of genes that encode components of the apoptotic machinery are directly targeted by activating or inactivating genetic lesions in cancer cells. In many tumours, deregulation of cell death underlies drug resistance and is a major reason for failure of conventional anticancer therapy. Upon activation, apoptosis unfolds in a precisely organised series of steps,
Compared Evaluation of Botulinum Toxin A and a Cosmetic Antiperspirant in the Treatment of Focal Axillary Hyperhidrosis  [PDF]

Journal of Cosmetics, Dermatological Sciences and Applications (JCDSA) , 2013, DOI: 10.4236/jcdsa.2013.33029
Abstract: Background: Primary focal hyperhidrosis can significantly reduce quality of life. Therefore a lot of treatment options in a range of conservative, physical and surgical techniques are available. Objective: To assess the efficacy of an antiperspirant containing aluminum chloride compared to a Botulinumtoxin A treatment for patients with primary focal hyperhidrosis. Methods and material: In this randomized, single-center, half-side trail, a clinical score was done by patients and physician to evaluate the severity of hyperhidrosis. Gravimetric tests were performed to gather the amount of sweat per unit of time. Furthermore the efficacy was determined using a four point questionnaire. Skin irritation was assessed by measuring pH value and transepidermal water loss. Results: A total of 22 patients were enrolled. Two weeks after baseline the hyperhidrosis level was significantly reduced (BTX-A: ﹣92.9%, AL: 66.7%). In addition both treatment options induced a significant reduction of sweat production (BTX-A: ﹣80.8%, AL: 68.8%). Please change in: Patients evaluated good resp, very good efficacy for both treatment options at day 28. pH value and TEWL never left physiological range. Conclusion: Both botulinum toxin A treatment and an antiperspirant containing aluminum chloride in the evaluated galenic formulation are an effective and safe treatment option for axillary focal hyperhidrosis.

Loops of Lagrangian submanifolds and pseudoholomorphic discs
Meike Akveld,Dietmar Salamon
Mathematics , 2000,
Abstract: The main theorem of this paper asserts that the inclusion of the space of projective Lagrangian planes into the space of Lagrangian submanifolds of complex projective space induces an injective homomorphism of fundamental groups. We introduce three invariants of exact loops of Lagrangian submanifolds that are modelled on invariants introduced by Polterovich for loops of Hamiltonian symplectomorphisms. One of these is the minimal Hofer length in a given Hamiltonian isotopy class. We determine the exact values of these invariants for loops of projective Lagrangian planes. The proof uses the Gromov invariants of an associated symplectic fibration over the 2-disc with a Lagrangian subbundle over the boundary.
