Terror mit Atomwaffen: reale Gefahr? Nukleare und Radiologische Waffen
NASA Astrophysics Data System (ADS)
Harigel, Gert G.
2006-01-01
Können Terroristen sich nukleare Massenvernichtungswaffen beschaffen? Dazu müssten sie ausreichende Mengen an waffenfähigem, spaltbarem Material stehlen. Selbst der Bau einer primitiven Atombombe erfordert einen hohen technischen Aufwand und Spezialisten. Wahrscheinlicher ist deshalb der Diebstahl einer kleinen taktischen Kernwaffe. Alternativ könnten Terroristen sich radioaktives Material aus zivilen Quellen beschaffen und daraus eine Schmutzige Bombe bauen. Eine solche radiologische Waffe wäre keine echte Massenvernichtungswaffe, doch ihre psychologische Wirkung könnte stark sein. Das macht sie für Terroristen attraktiv, weswegen diese Gefahr ernst genommen werden muss.

[The first deontology dissertation in Croatia (Desković, 1943)].
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
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]. This article will hopefully be of interest therefore to both clinician and historian alike. Clin. Anat. 29:679-684, 2016. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

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

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

Sources of Wilhelm Johannsen's genotype theory.
Roll-Hansen, Nils
2009-01-01
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

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.
