Exploring Meter in a Drum Circle

A series of jams based on different meters, starting with ¼ meter and sequentially adding a beat up to 9/4 meter (or beyond)

Foundational Rhythms for Drum Circles

Many drum circle facilitators use foundational rhythms to start a jam, establish a groove, and provide a structure within which other participants can improvise in a relatively freestyle manner. Twenty drum circle facilitators shared a sampling of foundational patterns drawn from universal drum rhythms, culturally specific drum styles, and speech rhythms

Pleistocene loess deposits and mollusc assemblages in the Eastern Pre-Alps

Die Lössablagerungen im nördlichen Wienerwald sind im Vergleich mit anderen Mittelgebirgsregionen aufgrund ihrer Mächtigkeit sehr eindrucksvoll. Charakterista in der Korngrößenverteilung zeigen deutlich, dass die Lösse im Hagenbachtal sich von denen anderer Lösssgebiete unterscheiden. Ein Vergleich mit Lössprofilen in Krems und Stillfried hat ergeben, dass der Löss im Hagenbachtal einen erhöhten Sandanteil aufweist und damit den Einfluss der Flysch-Sandsteine widerspiegelt. Das spricht für einen lokalen Sedimenteintrag und kurze äolische Transportstrecken. Zudem wurde der Löss unter kühl-humiden Paläoklimabedingungen zum Teil als Schwemmlöss abgelagert. Die malakologischen Ergebnisse stimmen mit den geomorphodynamischen Bedingungen überein. Die Umlagerungsprozesse haben zu einer intensiven Fragmentierung der Schalenreste geführt. Die malakologischen Untersuchungen belegen insgesamt 28 unterschiedliche Arten von terrestrischen Gastropoden mit 3283 Individuen. Die paläoökologische Auswertung spricht für sehr humide, kühle Klimabedingungen mit einer schwach ausgeprägten, klimatisch etwas günstigeren Phase.researc

Epidemiology and economic burden of measles, mumps, pertussis, and varicella in Germany: a systematic review

Damm O, Witte J, Wetzka S, et al. Epidemiology and economic burden of measles, mumps, pertussis, and varicella in Germany: a systematic review. INTERNATIONAL JOURNAL OF PUBLIC HEALTH. 2016;61(7):847-860.Despite the availability of vaccines and the existence of public vaccination recommendations, outbreaks of vaccine-preventable childhood diseases still cause public health debate. The objective of this systematic review was to provide an overview of the current epidemiology and economic burden of measles, mumps, pertussis, and varicella in Germany. We systematically reviewed studies published since 2000. The literature search was conducted using PubMed and EMBASE. Also, we used German notification data to give an up-to-date overview of the epidemiology of the four diseases under consideration. Thirty-six studies were included in our review. Results suggest that there is still considerable morbidity due to childhood diseases in Germany. Studies providing cost estimates are scarce. Comparative analyses of different data sources (notification data vs. claims data) revealed a potential underestimation of incidence estimates when using notification data. Furthermore, several studies showed regional differences in incidence of some of the diseases under consideration. Our findings underline the need for improved vaccination and communication strategies targeting all susceptible age and risk groups on a national and local level

Small renal carcinoma : the "when" and "how" of operation, active surveillance, and ablation

Small, locally restricted renal cell carcinoma less than 4 cm in size should ideally be removed operatively by nephron-sparing tumour enucleation (partial kidney resection). In an increasingly elderly population, there is a growing trend toward parallel incidence of renal cell carcinoma and chronic renal insufficiency, with the latter's associated general comorbidities. Thus, for some patients, the risks of the anaesthesia and operation increase, while the advantage in terms of survival decreases. Transcutaneous radio-frequency ablation under local anaesthesia, transcutaneous afterloading high-dose-rate brachytherapy under local anaesthesia, and percutaneous stereotactic ablative radiotherapy may offer a less invasive alternative therapy. Active surveillance is to be regarded as no more than a controlled bridging up to definitive treatment (operation or ablation), while watchful waiting, on account of the lack of prognostic relevance and the symptomatology of renal cell carcinoma, with its comorbidity-related, clearly reduced life expectancy, does not involve any further diagnostic or therapeutic measures
