Sarcophaga (Helicophagella) carlestolrai sp. n. wird aus Südspanien beschrieben. Basierend auf einer phylogenetischen Analyse die neue Art durch folgenden Merkmale der noverca-Gruppe innerhalb Untergattung Helicophagella Enderlein zugeordnet: Männliches Sternit 5 jeweils mit einem dicht besetzten Polster kurzen, dicken, stachelartigen Borsten am postero-medianen Rand an Basis Loben; länglichen ...

Microbiological tests have aided greatly in the isolation work on “L&o!x~ciZZus casei factor,” demonstrated by Snell and Peterson in 1940 (l), and “folic acid,” the nutrient required by Streptococcus lactis R as defined by Mitchell et al. (2). It seems likely that bacterial assays will continue to play an important role in the study of these compounds, since development of chemical methods has ...

The complexity of the nutritive requirements of Lactobacillus casei is known. The organism develops slowly in synthetic or semisynthetic media such as the one described by Landy and Dicken (1942). Assay media for this organism therefore include crude supplements like peptone (Teply and Elvehjem, 1945) or trypsinized casein (Roberts and Snell, 1946). The active principle responsible for the shor...

Ziel der Studie war die Analyse der Präzision dreidimensionaler Gelenkflächenund Knorpeldickenmessungen im Knie bei Verwendung einer schnellen, hochauflösenden Wasseranregungssequenz und eines semiautomatischen Segmentierungs-Algorithmus. Es wurden die Kniegelenke acht gesunder Probanden (Alter 22 bis 29 Jahre) mit einer Auflosung von 1,5 mm 0,31 mm 0,31 mm untersucht und jeweils vier sagittale...

The globalization of economic activities is a relatively recent phenomenon. Since the 1960s, the global economy has become increasingly interdependent and functionally integrated through cross-border flows of capital, goods and people. The role of transnational corporations (TNCs) in these cross-border activities is particularly important. The outward foreign direct investment (FDI) stock of TN...

This paper deals with the thickness and flatness control problem in heavy plate mills. After a short description of the industrial plant the first part of the paper is concerned with a new control strategy for the improvement of the thickness homogeneity over the plate length. This model–based concept takes into account valuable information from previous passes which, together with accurate mat...

Der Aufbau des Nukleosoms als Grundbaustein des Chromatins der Eukaryontenzelle, mit Ausnahme des Dinoflagellaten-Zellkerns, wird biochemisch und elektronenmikroskopisch vorgestellt als eine Einheit eines Oktamers aus Histonen (2 X H2A, 2XH2B, 2X H3, 2X H4) und einem Betrag von etwa 150 Basenpaaren DNA. Diese Partikel sind durch einen Zwischenbereich von weiteren etwa 50 Basenpaaren DNA verbund...

The 2 techniques are based upon the formulation of lead ing ion and trailing ion initially enunciated by Ornstein (3) and lean heavily on the suggestions for buffer strategy made by Williams and Reisfeld (6). The leading ion is po tassium, the trailing ion is fl-alanine in the pH 3.8 system or 3-picoline, (3-methylpyridine) (pK 6.29) in the pH 6.0 system. Acetic acid and cacodylic acid (pK 6.4)...

Studies of the nutritive requirements of the bacterium, Lactobacillus casei, have contributed much to our present knowledge of animal nutrition. It appears that the vitamin requirements of this microorganism are very similar to those of animals. Landy and Dicken (1) reported a microbiological assay method for six B vitamins with Lactobacillus casei and a medium of essentially known composition....

Introduction Peter Dicken (2004) lamented geographers' missing out on globalization and becoming more parochial in terms of research, and called for a revitalization of regional geography. Indeed, I often feel unsettled by the fact that, from time to time, geographers have to defend the position of geography, especially in recent response to the argument that globalization means the end of geog...
