Wirtschaftlichkeit der Hahnenmast in Zweinutzungshuhn- und „Bruderhahn“-Konzepten unter Berücksichtigung von Verarbeitungs- und Vermarktungsaspekten

Aufgrund der zunehmenden Diskussion um den Tierschutz ist das Töten männlicher Küken der Legeherkünfte aus tierethischer, gesellschaftlicher wie politischer Sicht kaum mehr vertretbar. Im Rahmen eines Forschungsprojektes, finanziert durch das Ministerium für Klimaschutz, Umwelt, Landwirtschaft, Natur- und Verbraucherschutz des Landes Nordrhein-Westfalen, untersuchte die Fachhochschule Südwestfalen das Marktpotential von Fleisch- und Wurstwaren männlicher Lege- und Zweinutzungshybride bei 10- und 20-wöchiger Mast. Es wurde dabei der Frage nachgegangen, inwieweit und unter welchen Bedingungen nachhaltige Erzeugungs-, Verarbeitungs- und Vermarktungsprozesse für den Geflügelsektor aufgebaut werden können, um auf das Töten der Hahnenküken verzichten zu können. Die Ergebnisse zeigen, dass für eine wirtschaftlich erfolgreiche Mast der Lege- und Zweinutzungshybriden eine hochwertige Vermarktung unabdingbar ist. Interessante produktpolitische Vermarktungsperspektiven ergeben sich für Dauerwurstwaren wie Salami. Die Mast der Zweinutzungshähne kann wirtschaftlich ohne Querfinanzierung über die Eier erreicht werden, wenn das Fleisch und die Wurstwaren im Bio-Marktsegment positioniert werden. Insgesamt ergeben sich durch die Herstellung hochwertiger Fleisch- und Wurstprodukte aus Lege- und Zweinutzungshähnen und die Einbettung in neuartige Vermarktungsmodelle mit passenden Marktpositionierungen realistische Perspektiven

Southeastern Arctic Ocean, seismic reflection images of cruise ark2018

In autumn 2018 a multichannel seismic reflection survey was performed in the southeastern part of the Amundsen Basin, on the Lomonosov Ridge and its transition to the Siberian Shelf. We present the new data, and a first glance at the findings, with the aim to enhance insights into the tectonic evolution, sedimentation history, and paleoceanography of the southeastern Arctic Ocean. Lines on the Lomonosov Ridge confirm the presence of 1600 m thick, undisturbed, parallel sedimentary layers. A prominent highamplitudereflector sequence within the strata can be used to directly correlate to previous seismostratigraphic models. A major aim of the expedition was the acquisition of cross lines relative to previous surveys covering the location of the upcoming IODP377 project. A 300 km long transect across the Amundsen Basin images a 3 km thick sedimentary sequence covering a rough acoustic basement. The highamplitudereflector sequence can also be traced in the basin, indicating widespread changes in tectonic and deposition conditions in the eastern Arctic Ocean. The crustal surface shows strong deformation, especially in the western part of the Basin, which can be associated with a reorganisation of tectonic plates accompanied by a significant decrease in spreading rates. A seamount, likely of a magmatic origin, was observed rising from the crust and penetrating all sedimentary layers. Dredgesampling on an outcrop at the western slope of the rise reveal a cover of consolidated sandand siltstones. Lines across the transition from the Lomonosov Ridge to the Laptev Sea Shelf image a more than 2 km thick sedimentary sequence overlying a rugged and faulted acoustic basement. At first glance, no indications of a larger transform fault can be detected, which could elucidate the tectonic relation between the ridge and the shelf. Several large mass wasting events or debris flows are indicated in the strata. An erosional channel with a sediment drift on its southern edge may provide clues to ocean current development

Limits of the seismogenic zone in the epicentral region of the 26 December 2004 great Sumatra-Andaman earthquake: Results from seismic refraction and wide-angle reflection surveys and thermal modeling

The 26 December 2004 Sumatra earthquake (Mw = 9.1) initiated around 30 km depth and ruptured 1300 km of the Indo-Australian Sunda plate boundary. During the Sumatra OBS (ocean bottom seismometer) survey, a wide angle seismic profile was acquired across the epicentral region. A seismic velocity model was obtained from combined travel time tomography and forward modeling. Together with reflection seismic data from the SeaCause II cruise, the deep structure of the source region of the great earthquake is revealed. Four to five kilometers of sediments overlie the oceanic crust at the trench, and the subducting slab can be imaged down to a depth of 35 km. We find a crystalline backstop 120 km from the trench axis, below the fore arc basin. A high velocity zone at the lower landward limit of the raycovered domain, at 22 km depth, marks a shallow continental Moho, 170 km from the trench. The deep structure obtained from the seismic data was used to construct a thermal model of the fore arc in order to predict the limits of the seismogenic zone along the plate boundary fault. Assuming 100C-150C as its updip limit, the seismogenic zone is predicted to begin 530 km from the trench. The downdip limit of the 2004 rupture as inferred from aftershocks is within the 350C 450C temperature range, but this limit is 210-250 km from the trench axis and is much deeper than the fore arc Moho. The deeper part of the rupture occurred along the contact between the mantle wedge and the downgoing plate

CHRDL1 Regulates Stemness in Glioma Stem-like Cells

Glioblastoma (GBM) still presents as one of the most aggressive tumours in the brain, which despite enormous research efforts, remains incurable today. As many theories evolve around the persistent recurrence of this malignancy, the assumption of a small population of cells with a stem-like phenotype remains a key driver of its infiltrative nature. In this article, we research Chordin-like 1 (CHRDL1), a secreted protein, as a potential key regulator of the glioma stem-like cell (GSC) phenotype. It has been shown that CHRDL1 antagonizes the function of bone morphogenic protein 4 (BMP4), which induces GSC differentiation and, hence, reduces tumorigenicity. We, therefore, employed two previously described GSCs spheroid cultures and depleted them of CHRDL1 using the stable transduction of a CHRDL1-targeting shRNA. We show with in vitro cell-based assays (MTT, limiting dilution, and sphere formation assays), Western blots, irradiation procedures, and quantitative real-time PCR that the depletion of the secreted BMP4 antagonist CHRDL1 prominently decreases functional and molecular stemness traits resulting in enhanced radiation sensitivity. As a result, we postulate CHRDL1 as an enforcer of stemness in GSCs and find additional evidence that high CHRDL1 expression might also serve as a marker protein to determine BMP4 susceptibility
