Claisen rearrangement ethers are a fundamental organic, pericyclic rearrangement reaction reagent. In the mechanism of a Claisen rearrangement, a vinyl allyl ether is needed to provide the necessary Lewis acid/base sites on the molecule for the rearrangement and are simply heated. This rearrangement was first discovered by heating up the title molecule, allyl phenyl ether. However, much like the Diels-Alder, Cope, and other pericyclic reactions, conformation and coordination of chemical groups is key to the Claisen mechanism. In this study, the authors present some structural characteristics of allyl phenyl ether from an analysis of the microwave spectra in the 8-14 GHz region using a CP-FTMW spectrometer. This is, to the authors knowledge, the first known microwave region study of the title molecule. Three conformers have been observed and assigned to date and will be discussed. Along with the rotational spectra, geometry calculations and potential energy surfaces performed at the MP2/6-311G++(3d,2p) level will be discussed and compared to the experimental results. Modeling the Claisen aromatic rearrangement mechanism using CP-FTMW spectroscopy will also be discussed. L. Claisen Chemische Berichte 45, 3157, October 1912.

Practice Report / Bericht aus der Praxis: An exploration of peer tutor roles and recruitment at German medical schools.

Almost all medical faculties in Germany actively employ peer tutors. However, little is known about the roles these tutors play from a faculty point of view. Also, there are only few descriptions of the tutor recruitment and selection processes. 32 of the medical faculties in Germany, where tutors are used in the training of medical students, were asked to provide information on the role and recruitment of tutors by means of a partially standardized questionnaire. At the surveyed faculties (return rate 28%), tutors are mostly employed for the purpose of teaching staff support. Even though desired in individual cases, tutors rarely play an active role in curriculum- or faculty development. The way tutor recruitment is handled strongly depends on the capabilities of the individual faculties and the way tutors are utilized. In many cases this process is structured, consisting of written and oral application phases, in other cases recruitment takes place without formal application procedures. The selection criteria, however, were found to be very similar at most faculties. The role of tutors from the faculties' point of view depends strongly on the respective nature of the tutorials, which are just as diverse as the approaches to tutor recruitment. Copyright © 2017.

modern time. Thus, on the one hand such rock glaciers postdate the formation of the mass movements, which enable a chronological constraint of this phenomenon on the base of our knowledge of climate history. On the other hand, those examples with rock glaciers linked at various altitudes with mass movements also mirror former stepwise permafrost degradation, where rock glacier formation moved to higher altitudes. In this respect, and envisaging a rising permafrost boundary, rock glacier formation on slopes affected by mass movements should be anticipated for the future. References: BARSCH, D.

Die Charakterisierung der klinischen Merkmale und des biologischen Potenzials von Spitznävi hat in den letzten Jahrzehnten breites Interesse gefunden. Das Ziel dieser Arbeit ist die Beschreibung der klinischen und dermatoskopischen Merkmale von Spitznävi sowie des klinischen Ergebnisses nach chirurgischer Exzision von Spitznävi in drei pädiatrischen Altersgruppen. Restrospektive Studie zur Analyse von klinischen Merkmalen, videodermatoskopischen Bildern, histopathologischen Diagnosen und Behandlungsergebnissen. Der Grad der Pigmentierung wurde sowohl klinisch als auch histopathologisch beurteilt. Bei 71 Patienten wurden 72 spitzoide Neoplasien entfernt. Videodermatologische Bilder lagen für 41 Patienten vor. Das Muster der Pigmentierung korrelierte signifikant mit dem Alter der Patienten: Hyperpigmentierte Läsionen waren bei Vorschulkindern selten, bei Patienten von 7 bis 12 Jahren und ab 13 Jahren dagegen häufiger. Eine histopathologische Diagnose von atypischen Spitznävi wurde selten durchgeführt. Keiner der Patienten, bei denen ursprünglich ein atypischer Spitznävus diagnostiziert worden war, entwickelte ein Lokalrezidiv oder Metastasen während der anschließenden Nachbeobachtung. Pigmentierte Spitznävi traten im Alter ab 13 Jahren häufiger auf. Die Studie bestätigt andere Berichte über die Altersverteilung von Pigmentierungsmustern und hebt die geringe Anzahl atypischer Spitznävi bei pädiatrischen Patienten hervor sowie das Ausbleiben von Rezidiven bei der langfristigen Nachbeobachtung. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

[The first deontology dissertation in Croatia (Desković, 1943)].

PubMed

Segota, I

1995-01-01

The first Croatian deontological dissertation, and probably one of the oldest in Europe, was written in Vienna in 1843. It was also published there in German. Our medical historians discovered it 40 years ago. However, its contents have up to now been unknown to our scientific and broader community. The manuscript, titled "About Physician's Duties to the State and to his Fellow-Men" (in German original: Joseph Descovich, Ueber die Pflichten des Artzes, Gegen den Staat uind seine Mitmenschen), is the work of a Dalmatian physician from Omis, Dr. Josip Desković. Nowadays when medical ethics has evolved into an independent academic discipline, and is rapidly spreading on all continents, this dissertation indicates that historical roots of medical ethics in Croats are by more than 150 years older compared to some other European countries, e. g. Sweden. The author presents the content of the dissertation and analyses it from ethical and sociological viewpoints. He relates it to Hippocratic ethics as well as to contemporary medical ethics termed bioethics, which is steadily establishing itself in modern medicine.

Historical roots of centrosome research: discovery of Boveri's microscope slides in Würzburg

PubMed Central

Scheer, Ulrich

2014-01-01

Boveri's visionary monograph ‘Ueber die Natur der Centrosomen’ (On the nature of centrosomes) in 1900 was founded primarily on microscopic observations of cleaving eggs of sea urchins and the roundworm parasite Ascaris. As Boveri wrote in the introductory paragraph, his interests were less about morphological aspects of centrosomes, but rather aimed at an understanding of their physiological role during cell division. The remarkable transition from observations of tiny dot-like structures in fixed and sectioned material to a unified theory of centrosome function (which in essence still holds true today) cannot be fully appreciated without examining Boveri's starting material, the histological specimens. It was generally assumed that the microscope slides were lost during the bombing of the Zoological Institute in Würzburg at the end of WWII. Here, I describe the discovery of a number of Boveri's original microscope slides with serial sections of early sea urchin and Ascaris embryos, stained by Heidenhain's iron haematoxylin method. Some slides bear handwritten notes and sketches by Boveri. Evidence is presented that the newly discovered slides are part of the original material used by Boveri for his seminal centrosome monograph. PMID:25047623

The mystery of the thymus gland.

Liu, Daniel; Ellis, Harold

2016-09-01

The thymus is the last organ in the human body to have its mechanisms fully understood, having had its function fully delineated more than 50 years ago (Miller , Tissue Antigens 63:509-517). Prior to this, the thymus gland has had an interesting history with theories having included a role in fetal growth and development before becoming more sinisterly, a cause of sudden infant death in the late 19th century known as status lymphaticus (Paltauf , Wien Klin Wochenschr 2:877-881). Until Miller (, Lancet 278:748-749) eventually proved its primarily immunological role, the history of this mysterious gland has closely mirrored the history of medicine itself, troubling the minds of pathologists such as Virchow (, Ueber die Chlorose und die damit zusammenhängenden Anomalien im Gefässapparate, insbesondere über "Endocarditis puerperalis," vorgetragen in der Sitzung der Berliner Geburtshülflichen Gesellschaft vom 12) and Grawitz (, Deut Med Wochenschr 22:429-431), surgeons such as Astley Cooper (, The Anatomy of the Thymus Gland) and Keynes (1953, Ann R Coll Surg 12:88), and eminent medical epidemiologists such as Greenwood and Woods [, J Hyg (Lond) 26:305-326].

From the Hensen net toward four-dimensional biological oceanography

Wiebe, Peter H.; Benfield, Mark C.

The development of quantitative zooplankton collecting systems began with Hensen (1887 Berichte der Kommssion wissenschaftlichen Untersuchung der deutschen Meere in Kiel5, 1-107; 1895 Ergebnisse der Plankton-Expedition der Humbolt-Stiftung. Kiel and Leipzig: Lipsius and Tischer ). Non-opening closing nets, opening closing nets (mostly messenger based), high-speed samplers, and planktobenthos net systems all had their start in his era - the late 1800s and early 1900s. This was also an era in which many of the fundamental questions about the structure and dynamics of the plankton in the worlds oceans were first posed. Fewer new systems were introduced between 1912 and 1950 apparently due in part to the two World Wars. The continuous plankton recorder stands out as a truly innovative device developed during this period ( Hardy 1926b Nature, London118, 630 ). Resurgence in development of mechanically-based instruments occurred during the 1950s and 1960s. A new lineage of high-speed samplers, the Gulf series, began in the 1950s and a number of variants were developed in the 1960s and 1970s. Net systems specifically designed to collect neuston first appeared in the late 1950s. During the 1960s, many focused field and experimental tank experiments were carried out to investigate the hydrodynamics of nets, and much of our knowledge concerning net design and construction criteria was developed. The advent of reliable electrical conducting cables and electrically-based control systems during this same period gave rise first to a variety of cod-end samplers and then to the precursors of the acoustically and electronically-controlled multi-net systems and environmental sensors, which appeared in the 1970s. The decade of the 1970s saw a succession of multi-net systems based both on the Bé multiple plankton sampler and on the Tucker trawl. The advent of the micro-computer stimulated and enabled the development of sophisticated control and data logging electronics for these

On Darboux's approach to R-separability of variables. Classification of conformally flat 4-dimensional binary metrics

NASA Astrophysics Data System (ADS)

Szereszewski, A.; Sym, A.

2015-09-01

The standard method of separation of variables in PDEs called the Stäckel-Robertson-Eisenhart (SRE) approach originated in the papers by Robertson (1928 Math. Ann. 98 749-52) and Eisenhart (1934 Ann. Math. 35 284-305) on separability of variables in the Schrödinger equation defined on a pseudo-Riemannian space equipped with orthogonal coordinates, which in turn were based on the purely classical mechanics results by Paul Stäckel (1891, Habilitation Thesis, Halle). These still fundamental results have been further extended in diverse directions by e.g. Havas (1975 J. Math. Phys. 16 1461-8 J. Math. Phys. 16 2476-89) or Koornwinder (1980 Lecture Notes in Mathematics 810 (Berlin: Springer) pp 240-63). The involved separability is always ordinary (factor R = 1) and regular (maximum number of independent parameters in separation equations). A different approach to separation of variables was initiated by Gaston Darboux (1878 Ann. Sci. E.N.S. 7 275-348) which has been almost completely forgotten in today’s research on the subject. Darboux’s paper was devoted to the so-called R-separability of variables in the standard Laplace equation. At the outset he did not make any specific assumption about the separation equations (this is in sharp contrast to the SRE approach). After impressive calculations Darboux obtained a complete solution of the problem. He found not only eleven cases of ordinary separability Eisenhart (1934 Ann. Math. 35 284-305) but also Darboux-Moutard-cyclidic metrics (Bôcher 1894 Ueber die Reihenentwickelungen der Potentialtheorie (Leipzig: Teubner)) and non-regularly separable Dupin-cyclidic metrics as well. In our previous paper Darboux’s approach was extended to the case of the stationary Schrödinger equation on Riemannian spaces admitting orthogonal coordinates. In particular the class of isothermic metrics was defined (isothermicity of the metric is a necessary condition for its R-separability). An important sub-class of isothermic metrics

the far future exceed the national assessment criteria for the handling of dredged material within coastal waterways more distinct than today. Therefore, adaptations of practices for the management of dredged material to higher particulate matter contaminations should be considered there in the medium or long-term perspective. On the one hand, e.g. the practices of depositing dredged- material within the water system might be adapted (BfG 2014). On the other hand, the implementation of remediation measures like those planned under the Water Framework Directive could mitigate the climate-induced increase of contaminants. However, before the planning of adaption measures begins, the respectively prevailing contamination status should be verified, as climate-induced changes of contaminant concentrations might be superimposed by direct anthropogenic activities, e.g. remediation measures to reduce contamination or construction works in waterways.

Shallow landslides: lessons from Sachseln 1997

NASA Astrophysics Data System (ADS)

Graf, Frank; Grunder, Karl

2017-04-01

A retrospective analysis of the heavy rainstorm in 1997 in Sachseln with almost 500 shallow landslides - half of them within forests, the other half in open land - reveals interesting perspectives. A total of 218 of these landslides were comprehensively documented, including 107 events triggered in forests that have been subjected to a more accurate analysis. A preliminary statistical approach based on distribution functions applied to slope inclination α and shear angle Φ' gives rise to the assumption that optimally managed forests have high protection potential - optimally managed in this context means the NaiS standard improved by findings of our project SOSTANAH. NaiS: www.bafu.admin.ch/publikationen/publikation/00732/index.html?lang=de SOSTANAH: www.slf.ch/ueber/organisation/oekologie/gebirgsoekosysteme/projekte/SOSTANH/index_EN Thus, it can be speculated that up to about four-fifths of these landslides could have been prevented, provided the forests fit the corresponding requirements. In an exemplary calculation, only about 80 ha of the investigated forest area (˜400 ha) would have been affected or roughly 20 landslides triggered of the 107 analysed. Given the specific characteristics for sites and improvement in Sachseln, the approximate costs for forest management, starting from an almost uncovered landslide area up to a mature protection forest (120 years), are estimated at about 35'000 CHF ha-1, yielding yearly 300 CHF ha-1 (price basis: 2016). The expected average annual expenditure to sustainably ensure continued existence of optimal protection forests is slightly lower. In the case of Sachseln, this amounts to about 12 Mio CHF for the whole area of 400 ha and a 100-year period (cost estimate by oeko-b, Stans: www.oeko-b.ch). The total damage of the 1997 event in Sachseln, with an estimated return period of 100 years, exceeded 120 Mio CHF. Of course, destruction was not merely caused by or obviously linked to shallow landslides. Nevertheless, from a

graphite heaters in the anvils. The T of the seats can then be kept below 700 K, providing much better mechanical stability of the cell. No evidence of deformation was observed even on softer steel seats under a P of 0.7 GPa with the anvils heated to 1150 K. The use of steel as seat material makes it possible to adapt the seat design efficiently to the experimental set-up required. Further advantages of DACs with internally heated anvils are: 1) rapid heating at rates exceeding 500 K/s, and 2) the possibility of imposing large T differences between the anvils. Special holders have been designed to hold anvils in their seats and to provide the electrical contacts up to 1400 K. In addition, new anvil geometries are being tested to avoid the chipping at the edges ot the culets observed when hard materials are used as gaskets. Although it can be shown that HT B-implantation has no effect on the extent of this flaking problem, chipping in electronically structured anvils can lead to short-circuiting between the electronic pathways of the structures and must be minimized. Low-angle bevels next to the culet can be shown to enhance the lifetime of edges and electronic structures. (1) Burchard et al. (1999),Bull. Liasion SFMC,11, 106. (2) Burchard et al.

Sources of Wilhelm Johannsen's genotype theory.

This paper describes the historical background and early formation of Wilhelm Johannsen's distinction between genotype and phenotype. It is argued that contrary to a widely accepted interpretation (For instance, W. Provine, 1971. The Origins of Theoretical Population Genetics. Chicago: The University of Chicago Press; Mayr, 1973; F. B. Churchill, 1974. Journal of the History of Biology 7: 5-30; E. Mayr, 1982. The Growth of Biological Thought, Cambridge: Harvard University Press; J. Sapp, 2003. Genesis. The Evolution of Biology. New York: Oxford University Press) his concepts referred primarily to properties of individual organisms and not to statistical averages. Johannsen's concept of genotype was derived from the idea of species in the tradition of biological systematics from Linnaeus to de Vries: An individual belonged to a group - species, subspecies, elementary species - by representing a certain underlying type (S. Müller-Wille and V. Orel, 2007. Annals of Science 64: 171-215). Johannsen sharpened this idea theoretically in the light of recent biological discoveries, not least those of cytology. He tested and confirmed it experimentally combining the methods of biometry, as developed by Francis Galton, with the individual selection method and pedigree analysis, as developed for instance by Louis Vilmorin. The term "genotype" was introduced in W. Johannsen's 1909 (Elemente der Exakten Erblichkeitslehre. Jena: Gustav Fischer) treatise, but the idea of a stable underlying biological "type" distinct from observable properties was the core idea of his classical bean selection experiment published 6 years earlier (W. Johannsen, 1903. Ueber Erblichkeit in Populationen und reinen Linien. Eine Beitrag zur Beleuchtung schwebender Selektionsfragen, Jena: Gustav Fischer, pp. 58-59). The individual ontological foundation of population analysis was a self-evident presupposition in Johannsen's studies of heredity in populations from their start in the early 1890s till his

al. (2015) which is based on machine learning algorithms depending on satellite imagery and expert knowledge. The data on urban land use and morphology are used for initialisation of the town energy balance scheme TEB, but are also useful for other urban canopy models or studies related to urban planning or modelling of the urban system. The sensitivity of canyon air and surface temperatures, air specific humidity and horizontal wind simulated by the town energy balance scheme TEB (Masson, 2000) regarding the dominant parameters within the range determined for the present urban structure of Vienna and the expected changes (MA 18 (2011, 2014a+b), PGO (2011), Amtmann M and Altmann-Mavaddat N (2014)) was calculated for different land cover zones. While the buildings heights have a standard deviation of 3.2m which is 15% of the maximum average building height of one block the built and unsealed surface fraction vary stronger with around 30% standard deviation. The pre 1919 structure of Vienna is rather uniform and easier to describe, the later building structure is more diverse regarding morphological as well as physical building parameters. Therefore largest uncertainties are possible at the urban rims where also the highest development is expected. The analysis will be focused on these areas.

results are Kurt Godel's seminal paper in 1931: "Ueber formal unentscheidbare Saetze der Principia Mathematica and verwandter System I" and Arrow's Nobel Prize winning "Impossibility Theorem" (Social Choice and Individual Values, 1951). Godel showed, unequivocally, that there is an enormous gap between what is being perceived as truth and what in fact can be proven as such. Arrow showed that the translation of individual preferences into a social order is impossible--except in a dictatorship. The unsolved controversies concerning the desirable or ideal structure of health care systems are impinged upon by these findings generally, and, in the case of the impossibility theorem, also directly. There is the impossibility of aggregating preferences and, at a deeper level, the impossibility of defining certain fundamental values, coupled with the problematic use of certain words, the absence of the possibility of creating, on a logically defined base, a complex system, complete and comprehensive in its own right. This is added to the fact that according to the elaboration by Stephen Wolfram in "A New Kind of Science", it is not easy to reduce complicated systems to simple components and to predict the continuation of their development even from simple basic laws without complicated calculations. All of these factors impede the construction of satisfying health care systems and leave obvious problems which overshadow the structure and the operation of health care systems.

.5‰ in the catchment of Lake Neusiedl are characteristic for waters derived from the cooler period of the Pleistocene (Rank et al., 1982), we conclude that groundwater of the deepest aquifer of the Seewinkel is not of Badenian to Sarmatian age but only several tens of thousands of years old. The artesian wells of the Seewinkel region drilled down to several hundreds of metres yielded groundwater with oxygen isotope ratio-values ranging between -11.90‰ and -10.83‰, values fitting well to waters of Pleistocene age of that region. Since wells discharging the Leitha Mountains also revealed oxygen isotope ratio-values varying from -11.10‰ to -10.22‰, we conclude that the mountain chains surrounding Lake Neusiedl basically charged both shallow and deeper aquifers of the Seewinkel. From oxygen isotope ratios of these groundwater bodies we therefore conclude that first the majority of aquifers of the Lake Neusiedl region was charged from the surrounding mountain chains, and second that salinity of soils in the Seewinkel region cannot be derived from up welling connate water, as has been proofed for Lake Kelemenszék area south of Budapest (Simon et al., 2011). There is no doubt on the fact, however, that differing amounts of free carbon dioxide in several aquifers of the Seewinkel region originate from deep-seated post volcanic activity in this region.

focused on the identification of very distant galaxy clusters, it makes the astronomers very optimistic about their future searches. The team is now carrying out detailed follow-up observations both from ground- and space-based observatories. They hope to find many more exceedingly distant clusters, which would then allow them to test competing theories of the formation and evolution of such large structures. "This discovery encourages us to search for additional distant clusters by means of this very efficient technique," says Axel Schwope, team leader at the Astrophysical Institute Potsdam (Germany) and responsible for the source detection from the XMM-Newton archival data. Hans Böhringer of the Max Planck Institute for Extraterrestrial Physics (MPE) in Garching, another member of the team, adds: "Our result also confirms the great promise inherent in other facilities to come, such as APEX (Atacama Pathfinder Experiment) at Chajnantor, the site of the future Atacama Large Millimeter Array. These intense searches will ultimately place strong constraints on some of the most fundamental properties of the Universe." More information This finding is presented today by Christopher Mullis at a scientific meeting in Kona, Hawaii, entitled "The Future of Cosmology with Clusters of Galaxies". It will also soon appear in The Astrophysical Journal ("Discovery of an X-ray Luminous Galaxy Cluster at z=1.4", by C. R. Mullis et al.).
