RealVelocityMeasuringDevice_E_Brauns
No full textWith respect to (the submission of) a third publication in Elsevier Optik (see the preceding publications [1,2]) on the concept of a RVMD (Real Velocity Measuring Device) as an Elsevier Optik follow-up publication of [1,2], this Mendeley set contains an mp4 video and two pdf documents. The mp4 video EMDR13_E_Brauns_Optics2021_June28-30_Kyoto.mp4 is linked to the conference Optics2021 (June28-30), Kyoto, with respect to a presentation by the author regarding [1,2]. The two pdf documents complement the contents of that third publication, on the concept of a RVMD. The pdf document EMDR14_E_Brauns_RVMD_USPTO_Patent_20070222971.pdf has the title 'Patent text&figures “Apparatus to measure real velocity and acceleration"'. That document includes a short introduction to the author's full USPTO patent text on the RVMD (deposited in 2006) and an Annex containing the full patent text (69 pages) itself (including all figures in their original colored layout). The pdf document EMDR15_E_Brauns_RealSpace_Torricelli_Hubble_RVMD.pdf has the title : 'The existence of Real Space and the relevance of the effect of Hubble’s Space Expansion, on observations by a RVMD (Real Velocity Measuring Device)'. That pdf document discusses the existence of RS (Real Space) on the basis of Torricelli's ingenious mercury barometer experiment. That pdf document also proofs that the Hubble space expansion can be totally neglected with respect to RVMD measurements.

No full textOphion dispar Brauns, 1895 Figs 6D, F, 9C, 10K, 31 A–B Ophion dispar Brauns, 1895: 42. Material examined Holotype, ♂ (HNHM); 2 ♂ ♂ (Sweden). Diagnosis Fore wing length 11 mm. Antenna with 44 flagellomeres. First flagellomere 3.0 times as long as wide. Central flagellomeres stout, about 1.2–1.3 times as long as wide. Subapical flagellomeres approximately 1.4 times as long as wide. Temple quite buccate, in lateral view 0.7 times as long as compound eye. Gap between compound eye and lateral ocellus 0.3 times the diameter of ocellus. Face below antennal sockets polished with very large and deep punctures (Fig. 31B). Malar space very long, about 0.8 times as long as mandibular base in male. Mandibular gape right-angled, with internal angles. Wing membrane clear. Ramellus very long, reaching 0.6 times the width of the discosubmarginal cell. Radius evenly curved. Nervellus broken above the middle by the discoidella. Mesopleuron polished with deep, large, regular punctures, space between punctures equal to their diameter. Epicnemial carina, in antero-ventral view, with pleurosternal angles distinctly anterior to sternal angles. Pleurosternal angles weakly defined and obtuse (Fig. 9C). Scutellum with strongly raised lateral carinae along its entire length (Fig. 6D). Propodeum with large distinct punctures, shining. Posterior transverse carina complete but weak in the Swedish specimens (stronger in the holotype). Anterior transverse carina absent laterally, only present centrally. Longitudinal carinae entirely absent (Fig. 10K). Hind trochantellus shorter than wide in dorsal view. Legs normal with hind femur about 7.0 times as long as wide. Inner spur of hind tibia long, about 0.5 times as long as metatarsus. Sclerotised part of first sternite ending distinctly posterior to spiracle at a distance about three times the distance between the spiracle and the lower margin of the first tergite (Fig. 6F). Colour Body testaceous. Head with inner and outer eye margins yellow (Fig. 31 A–B). Mandibular teeth black. DNA barcode The DNA barcode sequence of one Swedish specimens of Ophion dispar is available at the BOLD systems database (www.boldsystems.org, BIN. BOLD: ADG0606. Specimen code: STI-NJBC: 85). Ecology The two known Swedish males were collected by a light trap during June in a semi-open mixed forest. Otherwise, nothing is known about the ecology of this species. Distribution in Sweden Very rare and only known from the province of Uppland in the eastern part of Central Sweden. Remarks Easily distinguished from other Ophion species by the placement of the spiracle on the very elongate first tergite, the carination of the propodeum, the shape of the epicemial carina and the densely and deeply punctate mesosoma and face. The first author has studied a potential female of this species from Croatia. The specimen has 52 flagellomeres and the lateral carinae of scutellum weaker, but still clearly present. The posterior margin of the first sternite is further away from the posterior margin of the first tergite than in the studied males, but the first sternite is still ending posterior to the spiracle at a distance of about 2.0 times of the distance between hind margin of the first sternite and hind margin of the first tergite. In other respects similar to the male described here.Published as part of Johansson, Niklas & Cederberg, Björn, 2019, Review of the Swedish species of Ophion (Hymenoptera: Ichneumonidae: Ophioninae), with the description of 18 new species and an illustrated key to Swedish species, pp. 1-136 in European Journal of Taxonomy 550 on pages 62-64, DOI: 10.5852/ejt.2019.550, http://zenodo.org/record/347640
Reckonig with The Nazi- and GDR-Past based on Dirk Brauns' novels, "Im Inneren des Landes" (2012) and "Cafe Auschwitz" (2013). The Post-GDR-Perspective
No full textIn the presented article, the author describes both the disputes surrounding and the reception concerning two novels written by the contemporary German writer Dirk Brauns. The first, "Im Inneren des Landes", published in 2012 in Germany and unknown to the Polish readers reckons with the DDR dictatorship; the second, "Café Auschwitz", published in 2013 and only in Polish, deals with the crimes committed under national socialism. The central aspect of both literary works is the problem of memory and oblivion, and within the context of their receptions, both have become very important. The author has also included an appendix related to the Polish translation of "Café Auschwitz"; it contains suggestions as to how to correct the Polish translation
Efficient sampling methodologies for lake littoral invertebrates in compliance with the European Water Framework Directive
No full textLake shores are characterised by a high natural variability, which is increasingly threatened by a multitude of anthropogenic disturbances including morphological alterations to the littoral zone. The European Water Framework Directive (EU WFD) calls for the assessment of lake ecological status by monitoring biological quality elements including benthic macroinvertebrates. To identify cost- and time-efficient sampling strategies for routine lake monitoring, we sampled littoral invertebrates in 32 lakes located in different geographical regions in Europe. We compared the efficiency of two sampling methodologies, defined as habitat-specific and pooled composite sampling protocols. Benthic samples were collected from unmodified and morphologically altered shorelines. Variability within macroinvertebrate communities did not differ significantly between sampling protocols across alteration types, lake types and geographical regions. Community composition showed no significant differences between field composite samples and artificially generated composite samples, and correlation coefficients between macroinvertebrate metrics calculated with both methods and a predefined morphological stressor index were similar. We conclude that proportional composite sampling represents a time- and cost-efficient method for routine lake monitoring as requested under the EU WFD, and may be applied across various European geographical regions
Effects of shoreline alteration and habitat heterogeneity on macroinvertebrate community composition across European lakes
No full textHuman lake shore alterations often result in a substantial decrease of littoral and riparian habitat diversity and physical complexity, but the intensity at which shore alterations affect biodiversity may differ among European geographical regions. We tested if the response of littoral macroinvertebrate communities to human shoreline alterations is consistent among geographical regions. We compared community composition and diversity of human altered with those of unmodified littoral zones from 51 lakes across seven European countries in four geographical regions based on pooled composite as well as habitat-specific macroinvertebrate samples. Taxon richness and community composition differed among shore types and different habitats in all geographic regions, with morphological alteration having an overall negative effect on macroinvertebrate taxon richness. In addition, habitat heterogeneity also had a strong effect on littoral communities, with highest taxon richness found in the structurally complex macrophyte habitats in all regions. Average proportional densities of Diptera and Oligochaeta taxa generally increased in morphologically altered shores in all geographical regions, while Bivalvia, Crustacea, Ephemeroptera, Gastropoda and Trichoptera showed comparatively lower numbers in many anthropogenically altered sites. Furthermore, taxon richness was positively correlated with habitat diversity. We were able to relate changes in littoral communities to anthropogenic shoreline alterations, and linked the effect to the loss of habitats and habitat complexity. The results of our study demonstrate that littoral macroinvertebrates respond consistently negative to the influence of morphological alterations across European geographical regions in terms of biodiversity. While macroinvertebrates have previously been identified to be useful descriptors of morphological change in single countries/regions, we can now validate that they can be used to assess the ecological status of lakes in terms of morphological alterations across European regions. Our results can be used to further improve ealready existing WFD-compliant multimetric indices, for example by including taxa groups, which show a strong reaction to shoreline alterations. This could be supported by the inclusion of a suit of indicator taxa reflecting the loss of complex habitats such as macrophytes in the lake littoral

Human impacts on the structure and ecological function of littoral macroinvertebrate communities in lakes
No full textDas litorale Makrozoobenthos ist eine bedeutende biotische Komponente in Seen und trägt substantiell zur Biodiversität und Funktion von Seeökosystemen bei. Allerdings unterliegt das Litoral zunehmenden anthropogenen Nutzungen, deren ökologische Auswirkungen jedoch kaum quantifiziert wurden. In dieser Doktorarbeit wurde untersucht, welche Bedeutung maßgebliche Umweltfaktoren auf die Zusammensetzung des litoralen Makrozoobenthos haben, und wie sich anthropogene Nutzungen auf die Zusammensetzung und Funktion des Makrozoobenthos auswirken. Die Zusammensetzung des Makrozoobenthos wurde durch die Uferstruktur, Trophie und das hydrodynamische Regime bestimmt. Die faunistische Ähnlichkeit zwischen Habitaten war jedoch signifikant geringer als zwischen Trophiestufen, so dass die Uferstruktur, und nicht die Trophie, einen größeren Einfluss auf das Makrozoobenthos hat. Strukturelle Degradation führte zu einer Reduktion der Habitatheterogenität, was eine signifikante Verringerung der Diversität und eine signifikant veränderte Artenzusammensetzung verursachte. Infolgedessen war die Komplexität der Makrozoobenthos-Nahrungsnetze an degradierten Ufern signifikant geringer als an natürlichen Ufern. Erhöhte Wasserstandsschwankungen führten zum Ausfall von Wurzelhabitaten und der damit assoziierten Makrozoobenthos-Gemeinschaft. Schiffsinduzierter Wellenschlag führte zur Verdriftung des Makrozoobenthos von ihren Habitaten bereits bei geringen Sohlschubspannungen. Die Effekte von Wasserstandsschwankungen und schiffsinduziertem Wellenschlag wurden jedoch durch Habitate mit hoher struktureller Komplexität verringert. Mit dieser Doktorarbeit konnte ich ein mechanistisches Verständnis darüber erarbeiten, wie anthropogene Nutzungen die Wirkungsbeziehungen zwischen Umweltfaktoren und Artengemeinschaften verändern und welche ökologischen Auswirkungen dies hat. Diese Kenntnisse können als wissenschaftliche Basis zur Bewertung von anthropogenen Beeinträchtigungen des Litorals dienen.Littoral macroinvertebrates are an important biotic component of lakes by contributing substantially to the biodiversity and functioning of lake ecosystems. Humans alter the littoral and riparian areas for various purposes, but the resulting ecological impacts on littoral macroinvertebrates have not been quantified. In this thesis, I investigated the significance of key environmental factors for littoral macroinvertebrate communities and how human alterations of these environmental factors impact the structure and function of macroinvertebrate communities. Macroinvertebrate community composition was significantly related to littoral structure, trophic state and the hydrodynamic regime. The significantly higher compositional dissimilarities among habitats than among trophic state suggested that littoral structure was the more important driver of community composition. Structural degradation caused a significant reduction of habitat heterogeneity and resulted in a significant reduction of species diversity and a significant altered community composition. This caused a significant reduction of macroinvertebrate food web complexity and substantial alterations of the trophic base of the food webs. Climate-change induced water level fluctuations resulted in the loss of root habitats and the specific community associated with this habitat. Ship-induced waves had substantial direct effects, since macroinvertebrates were detached from their habitats by waves even at moderate shear stress levels. However, the impacts of water level fluctuations and ship-induced waves were mitigated by the presence of habitats with high structural complexities. This thesis provided a mechanistic understanding of how human activities alter relationships between environmental factors and biotic communities. This knowledge can be used to develop scientifically sound approaches to assess the persistent human impacts on lake ecosystems

Bezzi, 1922: 80 – diagnosis; listed specimens in HNHM & Bezzi’s personal collection [= MSNM]. Two syntypes located in MSNM: South Africa (Eastern Cape): 1 Ψ, Willowmore, 20.xi. 1906 (Dr Brauns); 1 Ψ, same except, 1.i. 1907. Hesse, 1956: 86 – described from a topotypic male (1.xi. 1909) from Dr Brauns collection and a female from Koup Karoo. The topotypic specimen, now in NMSA, is in fact a female and also bears an old determination label, probably by Brauns, reading “ Tomomyza pallipes Bezzi / Ψ/ unique specimen”. Evenhuis & Greathead, 1999: 288 – listed 2 syntypes in MSNM. Types: The female syntypes in HNHM were destroyed in 1956. The syntype in MSNM collected on 20.xi. 1906 has a damaged left wing; the other collected on 1.i. 1907 is in good condition and is here designated lectotype (Fig. 15–16). Remarks: Hesse (1956) considered that the specimen from Dr Brauns’s collection had been seen by Bezzi because of the date of collection. However, Bezzi said that it was ‘named by the late Dr Brauns’ which is not consistent with Bezzi having examined it. Possibly, as suggested above, Brauns retained duplicates that he labelled when he received names from Bezzi. The lectotype and paralectotype females accord with the description given by Hesse.Published as part of Greathead, David J. & Evenhuis, Neal L., 2004, New species of Bombylioidea in Mario Bezzi's Unpublished Hungarian Museum Manuscript, pp. 1-56 in Zootaxa 773 on page 28, DOI: 10.5281/zenodo.15846

Two syntypes found in MSNM: South Africa (Eastern Cape): 1 ɗ, Willowmore, 5.xi. 1906 (Dr Brauns); 1 ɗ, same except, 20.xi. 1906. Hesse, 1956: 90 – described from a topotypic male in Dr Brauns collection and a female from the Little Karoo (SAMC). The topotypic male, now in NMSA, was collected in Willowmore, 1.xii. 1920, and bears an old determination label, probably by Dr Brauns “ Tomomyza barbatula Bezz / ɗ/unique specimen”. Evenhuis & Greathead, 1999: 288 – 2 syntypes listed in MSNM. Types: The syntypes in HNHM were destroyed in 1956. Two syntype males in Bezzi’s own collection in MSNM are in good condition but the one captured on 5.xi. 1906 lacks the right middle leg. Consequently, the other male collected on 20.xi. 1906 is here selected as lectotype (Fig. 14). Remarks: The two males lectotype and paralectotype from Bezzi’s collection in MSNM accord with the description given by Hesse (1956). It is a distinctive species with an almost entirely blackish cuticle and hyaline wings.Published as part of Greathead, David J. & Evenhuis, Neal L., 2004, New species of Bombylioidea in Mario Bezzi's Unpublished Hungarian Museum Manuscript, pp. 1-56 in Zootaxa 773 on pages 27-28, DOI: 10.5281/zenodo.15846

Bezzi, 1921 a: 47, 52 – key and diagnosis; 1 ɗ, South Africa (Western Cape): Hex River, xii. 1884 (L. Péringuey) (SAMC). Bezzi, 1922: 74 – mentioned its presence in his (1921 a) key and in his anticipated Hungarian paper; specimens of both sexes ex Willowmore, xi and ii (in HNHM and Bezzi’s collection). MSNM has two syntypes from Willowmore: 1 ɗ, xi. 1912 (Dr Brauns); 1 Ψ, 28.ii. 1915 (Dr Brauns). These specimens also bear small brown labels ‘ 42 Bezzi’ and ‘ 44 Bez’ respectively. The Brauns collection in NMSA has 3 ɗɗ and 3 ΨΨ collected on 25.xi. 1912, 1ɗ also has a ’ 42 Bezzi’ label and 1 Ψ collected on 15.xii. 1919 with a ‘Bezzi 44 ’ label. These specimens are considered to be duplicates retained by Dr Brauns and if this is so are not syntypes. Hesse, 1938: 361 – description from the Hex River specimen and many others in SAMC and BMNH. Evenhuis & Greathead, 1999: 86 – listed the holotype (destroyed) in HNHM. Types: Bezzi (1921 a) stated that the “ Type ” was in the Hungarian Museum. This is enough to consider it as the holotype. The other specimens listed by Bezzi (1921 a, 1922) are paratypes. The holotype was destroyed in the 1956 uprising. Remarks: Bezzi (1921 a) diagnosed A. macrophthalmus by giving comments on a few characters that distinguished it from A. erinaceus Bezzi (thus effectively validating the name). It is a common and widespread species in the karoo biomes of South Africa.Published as part of Greathead, David J. & Evenhuis, Neal L., 2004, New species of Bombylioidea in Mario Bezzi's Unpublished Hungarian Museum Manuscript, pp. 1-56 in Zootaxa 773 on page 20, DOI: 10.5281/zenodo.15846
