Study of polychlorinated biphenyls in street dust by supercritical fluid extraction-gas chromatography/mass spectrometry
1996
Street dust samples have been collected from highways, urban streets, a gasoline station, a pedestrian tunnel, and railway stations in some German cities. Nine polychlorinated biphenyls (PCBs from tri- to heptachlorobiphenyls) were quantitatively extracted by supercritical fluid extraction with CO2 at 200 bar and 40°C and analyzed by gas chromatography/mass spectrometry. The highest PCB loads (sum of the nine studied PCBs) of ca. 1 to 4 μg/g have been found in the samples from motorway A60 near Mainz, while in almost all other samples PCBs could be detected at only ca. 0.1 to 1 μg/g. At three sampling sites, a winter maximum of the PCB concentrations has been found.
Autumn migration of soaring birds through the Gebel El Zeit Important Bird Area (IBA), Egypt, threatened by wind farm projects
2011
SummarySystematic bird observations were performed during autumn 2006 in the migration bottleneck area of Zeit Bay, Egypt (27.73°N, 33.51°E), situated on the coast of the Gulf of Suez, opposite southern Sinai. Owing to the strong northerly winds in that area, considerable pressure exists to construct wind farms. A total of 145,432 soaring birds, including 134,599 storks and 9,376 raptors over a period of 453.6 hours were observed between 20 August and 29 October by two teams working daily in two shifts. White Stork Ciconia ciconia and European Honey Buzzard Pernis apivorus were the most numerous species (91.4% and 5.7% respectively) of all soaring birds observed. As both species migrate ear…
Cittadinizzazione e policy migratorie nella Sicilia occidentale : Progettare servizi innovativi rafforzando le Pubbliche Amministrazioni in attuazion…
2021
L’accesso ai servizi della pubblica amministrazione è spesso, per la popolazione migrante, un cercare la chiave giusta fra un numero spropositato di chiavistelli. Evidenziare come l’inserimento di alcuni servizi innovativi, fra i quali gli sportelli Mi.Main (Migration Mainstreaming) progettati e implementati da giovani laureati all’interno degli uffici della P.A., abbia di fatto favorito processi di “cittadinizzazione”, è stato lo scopo di questo volume. Preliminari ad ogni processo di inclusione sono infatti gli “atti di cittadinanza” che attraversano e ancorano l’universalità dei diritti umani al riconoscimento dei bisogni e delle priorità della persona. Questo volume, descrive come due t…
From Theatre to Theatricality—How to Construct Reality
1995
At the end of the nineteenth century, the dominance of language, so typical of Western culture since the Renaissance, was increasingly challenged. As early as 1876, Nietzsche wrote on Richard Wagner in Thoughts Out of Season:He was the first to recognize an evil which is as widespread as civilization itself among men; language is everywhere diseased, and the burden of this terrible disease weighs heavily upon the whole of man's development. Inasmuch as language has retreated ever more and more from its true province— the expression of strong feelings, which it was once able to convey in all their simplicity—and has always had to strain after the practically impossible achievement of communi…

Cloning and Characterization of Overlapping DNA Fragments of the Toxin A Gene of Clostridium difficile
1989
Clostridium difficile, a human pathogen, produces two very large protein toxins, A and B (250-600 kDa), which resist dissociation into subunits. To clone the toxin A gene, a genomic library of 3-8 kb chromosomal DNA fragments of C. difficile strain VPI 10463 established in pUC12 was screened with a rabbit polyclonal toxin A antiserum. Thirty-five clones were isolated which carried 2.5-7.0 kb inserts representing a 10 kb region of the C. difficile genome. All the inserts were oriented in the same direction, suggesting that toxin A gene expression was under control of the lac promoter of the pUC12 vector. Western blot experiments revealed the presence of low amounts of fusion proteins of vari…
Musical training facilitates the neural discrimination of major versus minor chords in 13-year-old children
2012
Music practice since childhood affects the development of hearing skills. An important classification in Western music is the chords’ major-minor dichotomy. Its preattentive auditory discrimination was studied here using a mismatch negativity (MMN) paradigm in 13-year-olds with active hobbies, music-related (music group) or other (control group). In a context of root major chords, root minor chords and inverted major chords were presented infrequently. The interval structure of inverted majors differs more from root majors than the interval structure of root minors. However, the identity of the chords is the same in inverted and root majors (major), but different in root minors. The deviant…

Applicability of the Poisson distribution to model the data of the German Children's Cancer Registry.
1995
Since 1980 the German Children's Cancer Registry has documented all childhood malignancies in the Federal Republic of Germany. Various statistical procedures have been proposed to identify municipalities or other geographic units with increased numbers of malignancies. Usually the Poisson distribution, which requires the malignancies to be distributed homogeneously and uncorrelated, is applied. Other discrete statistical distributions (so-called cluster distributions) like the generalized or compound Poisson distributions are applicable more generally. In this paper we present a first explorative approach to the question of whether it is necessary to use one of these cluster distributions t…
Preliminary results of the 2017 season in the Amazonian earthen structures known as geoglyphs.
2018
O trabalho realizado pela equipe de pesquisa multidisciplinar, liderada pela Universitat de Valencia Estudi General (UVEG) e a Universidade Federal do Acre (UFAC), de detalhamento da topografia, em especial na RESEX Chico Mendes, criou progresso significativo no conhecimento das estruturas de terra construídas na paisagem amazônica, conhecidas popularmente como geoglifos, no que se refere a aplicação de topografia de alta precisão para algumas das estruturas, compreensão geral fenômeno e aplicação de uma nova estratégia de pesquisa, com o auxílio de ferramentas como o Google Earth, Google Maps, GPX, OpenStreetMap e Lidar. Ainda há muito trabalho de campo a ser feito na Amazônia Ocidental, n…
