Supersurface electron scattering, i.e., electron energy losses and associated deflections in vacuum above the surface of a medium, is shown to contribute significantly to electron spectra. We have obtained experimental verification (in absolute units) of theoretical predictions that the angular distribution of the supersurface backscattering probability exhibits strong oscillations which are anticorrelated with the generalized Ramsauer-Townsend minima in the backscattering probability. We have investigated 500-eV electron backscattering from an Au surface for an incidence angle of 70° and scattering angles between 37° and 165°. After removing the contribution of supersurface scattering from the experimental data, the resulting angular and energy distribution agrees with the Landau-Goudsmit-Saunderson (LGS) theory, which was proposed about 60 years ago, while the raw data are anticorrelated with LGS theory. This result implies that supersurface scattering is an essential phenomenon for quantitative understanding of electron spectra.
Suchen Sie auch den Schlüssel zum besseren Verständnis von Mythologie, Kunst und Literatur? Dann sollten Sie das Weltbild des Impurismus studieren. Es wird Ihnen die Augen öffnen für bislang hermetische Zusammenhänge, und Sie werden erkennen, was der Chorus mysticus (Faust II Ende) meint, wenn er sagt: "Alles Vergängliche Ist nur ein Gleichnis." Erde und Himmel, alles Materielle und alle Geistgebilde, der Kosmos und alle Lebewesen --- ein Gleichnis wofür? Wenn Sie die Antwort finden, werden Sie verstehen, warum die Wissenden unsere Kulturszene dominieren. Sie brauchen keine Forschungsnische zu suchen, wenn Sie das weite Feld des Impurismus mit Literatur- und Sprachwissenschaft beackern; denn "Poesie ist die Muttersprache des menschlichen Geschlechts" (Hamann: Aestetica in nuce).
Impurismus ist eine uralte Weltanschauung und eine alte Poetik. Beides habe ich in meinem Buch von 2007 Illustrierte Poetik des Impurismus ausführlich dargestellt. Da ich mich nicht wiederholen will, kann ich die umfangreichen Funde zum Thema hier nicht erneut vortragen. Andererseits soll der Leser dieser Fortsetzung nicht ganz unvorbereitet in die Materie einsteigen. Deshalb will ich einige nackte Fakten als Erinnerung hier zusammenstellen, muß aber doch dringend auf die anschaulichen Grundlagen in dem genannten Buch verweisen, sonst verschreckt die in aller Kürze vorgetragene Ungeheuerlichkeit der ganzen Entdeckung manchen willigen Leser. ...
Das Spiel ist aus
(2007)
Dieser bekannte Titel (ein Drama von Sartre / ein Gedicht von Bachmann) soll hier mit neuem Inhalt gefüllt werden, zunächst mit "Impurismus" als einer spielerischen Verschlüsselung von Literatur, dann mit Hinweisen auf das planmäßige Verdummungsspiel, das die Eingeweihten mit ihren an Kunst interessierten Mitbürgern treiben.
Der Impurismus ist eine literarische Strömung, die durch Jahrtausende geht, ein geistreiches, planvolles Spiel zur Produktion von hermetischer Literatur über ein tabuisiertes Thema (Sex). Zu dieser "littérature impure" gehört ein Geheimnis aus dem Urwissen der ältesten Kulturen, aus einer Zeit, in der Philosophie, Theologie und Kosmologie noch eins waren. Das alte Wissen wurde in den Bereichen konserviert, die bis heute von der konventionellen Wissenschaft als "esoterisch" ausgegrenzt werden (Astrologie, Kabbala, Tarot). Viele Autoren aber verschlüsseln ihre Texte mit der alten Lehre und verstecken sie hinter einer religiösen, spielerisch-humoristischen oder sozialkritisch engagierten Maske. Deshalb bleiben viele Texte trotz Interpretation hermetisch, besonders solche in der "Weltsprache der modernen Poesie" (Enzensberger). Eine neue Methode der literarischen Analyse (mit 57 Varianten der planvollen Verfremdung von Wörtern) kann die impuristische Literatur dekodieren. Dazu gehört als Raumordnung das alte "Weltbild der Windmühle". Dieses Literaturspiel wird als sublime Kulturtätigkeit aufgedeckt. Die Einzelseiten dieser Homepage können nur einige Einblicke in schwierige Zusammenhänge geben, die im langsamen Vortrag des Buches leichter zu verstehen sind. Auf beiden Wegen muß man sich Zeit nehmen und am besten einen philosophischen Wissenshunger mitbringen.
Namibia is known to be the most arid country south of the Sahara. Average annual rainfall is not only relatively low in most parts of the country, it is also highly variable. Only 8 per cent of the country receives enough rain during a normal rainy season to practice rainfed cultivation. At the same time between 60 per cent and 70 per cent of the population depend on subsistence agro-pastoralism in non-freehold or communal areas. Against the background of rising unemployment, the livelihoods of the majority of these people are likely to depend on natural resources in the foreseeable future.
Natural resources generally are under considerable strain. As the rural population increases, so is the demand for natural resources, land and water specifically. Dependency on subsistence farming which is the result of large scale rural poverty exacerbates the problem. Large parts of the country are stocked injudiciously, resulting in overgrazing and water is frequently overabstracted, leading to declining water tables (MET 2005: 2).
Unequal access to both land and water has prompted government to introduce reforms in these sectors. These reforms were guided by the desire to manage resources more sustainably while providing more equal access to them. In terms of NDP 2, sustainability means to use natural resources in such a way so as not to ‘compromise the ability of future generations to make use of these resources’ (NDP 2: 595).
Immediately after Independence government started reform processes in the land and water sectors. However, these reforms have happened at different paces and largely independent of each other. Increasingly policy makers and development practitioners realised that land and water management needed to be integrated, as decisions about land management and land use options had a direct impact on water resources. Conversely the availability of water sets the parameters for what is possible in terms of agricultural production and other land uses. The north-central regions face a particular challenge in this regard as the region carries more livestock than it can sustain in the long run. At the same time, close to half the households do not own any livestock. Access to livestock by these households would improve their abilities to cultivate their land more efficiently in order to feed themselves and thus reduce poverty levels.
But livestock are a major consumer of water. In 2000 livestock was consuming more water than the domestic sector. The figures were 77Mm3/a and 67Mm3/a respectively (Urban et al. 2003 Annex 7: 2). This situation has prompted a Project Progress Report on the Namibia Water Resources Management Review in 2003 to conclude that Given the extreme water scarcity in most parts of the country, land and water issues are closely linked. It therefore seems indispensable to mutually adjust land – and water sector reform processes (Ibid: 20).
This paper will briefly look at four institutions that are central to land and water management with a view to assess the extent to which they interact. These are Communal Land Boards, Water Point Committees, Traditional Authorities and Regional Councils. A discussion of relevant policy documents and legislative instruments will investigate whether the existing policy framework
provides for an integrated approach or not. Before doing this, it appears sensible to briefly situate these four institutions in the wider maze of institutions operating at regional and
sub-regional level. All these institutions – important as they are in the quest to improve participation at the regional and sub-regional level – are competing for time and input fros mallscale farmers.
Hereditary angioedema (HAE) in children and adolescents : a consensus on therapeutic strategies
(2012)
Hereditary angioedema due to C1 inhibitor (C1 esterase inhibitor) deficiency (types I and II HAE-C1-INH) is a rare disease that usually presents during childhood or adolescence with intermittent episodes of potentially life-threatening angioedema. Diagnosis as early as possible is important to avoid ineffective therapies and to properly treat swelling attacks. At a consensus meeting in June 2011, pediatricians and dermatologists from Germany, Austria, and Switzerland reviewed the currently available literature, including published international consensus recommendations for HAE therapy across all age groups. Published recommendations cannot be unconditionally adopted for pediatric patients in German-speaking countries given the current approval status of HAE drugs. This article provides an overview and discusses drugs available for HAE therapy, their approval status, and study results obtained in adult and pediatric patients. Recommendations for developing appropriate treatment strategies in the management of HAE in pediatric patients in German-speaking countries are provided.Conclusion Currently, plasma-derived C1 inhibitor concentrate is considered the best available option for the treatment of acute HAE-C1-INH attacks in pediatric patients in German-speaking countries, as well as for short-term and long-term prophylaxis.
Objective. A study supported by the EULAR and the ACR being conducted to establish classification criteria for polymyalgia rheumatica (PMR) will include ultrasound examination of the shoulders and hips. Ultrasound (US) depicts glenohumeral joint effusion, biceps tenosynovitis, subdeltoid bursitis, hip joint synovitis, and trochanteric bursitis in PMR. These findings may aid in distinguishing PMR from other diseases. The purpose of this study was to assess standards and US interreader agreement of participants in the PMR classification criteria study. Methods. Sixteen physicians in four groups examined shoulders and hips of 4 patients and 4 healthy adults with ultrasound. Overall agreement and interobserver agreement were calculated. Results. The overall agreement (OA) between groups was 87%. The OA for healthy shoulders was 88.8%, for healthy hips 100%, for shoulders with pathology 85.2%, and 74.3% for hips with pathology, respectively. Conclusion. There was a high degree of agreement found for the examination of healthy shoulders and pathologic hips. Agreement was moderate for pathologic shoulders and perfect for healthy hips. US of shoulder and hips performed by different examiners is a reliable and feasible tool for assessment of PMR related disease pathology and can be incorporated into a classification criteria study.
