Separation of liquid-liquid dispersions with multiple phases involves different interactions between the different dispersed species present in the system, which makes it difficult to predict e.g. the separation behaviour. Nevertheless such systems are relevant in chemical engineering e.g. for systems involving gas bubbles and simultaneously solid particles like in a fermentation broth. Models for describing the sedimentation behaviour as a basis for settler design are available in principle but have not been systematically validated for variation in size-distribution and e.g. density differences between the various species in the system. Thus, to design technical separation equipment, the separation process has to be better understood, which requires the study of the sedimentation as a first step. This project is focused on the interactions which may occur between each species during the sedimentation e.g. the effect on sedimentation of descending particles when they meet ascending drops. However, a proper study of the sedimentation with fluid phases is difficult due to other phenomena occurring simultaneously, e.g. coalescence. To overcome this issue, the use of gel beads is proposed, which due to their solid interface cannot coalesce. In addition, it is easy to define their parameters which are the density, the hardness and the size distribution. Besides, they can also be preserved during an extended period of time, experiments can thus be reproduced many times with identical beads. During the project, gel beads are designed with different particle size distributions and with different densities. Different batches of the produced gel beads will be mixed to simulate systems with different dispersed phases discriminated via density and different size distributions. With these multiple dispersed phases Experiments will be performed in a settling cell in order to evaluate the overall sedimentation velocity at certain hold up. Simultaneously a new method for measurement of local hold-up profile in the dispersion is tested, which allows hold-up measurement even in opaque systems. Finally sedimentation models found in the literature are compared and adapted to experimental results for predict the sedimentation of systems which involve different dispersed phases. In the presentation the new hold-up measurement will be presented together with an error analysis, experiments on the sedimentation of multiple dispersed phases and the model evaluation will be presented.

Simple repetitive DNA sequences have been regarded as mere "junk" present in all eukaryotic genomes. In fact, mixed simple repeat (gt)n(ga)m sequences are present in major histocompatibility complex MHC-DRB genes for long evolutionary times, including such distant animals as artiodactyla and man. We describe herein an unsophisticated method which reveals that at least certain simple repetitive (gt)n(ga)m sequences bind nuclear proteins and show characteristics of a specific DNA-protein interaction via gel retardation.

The gelatinase A (72 kDa type IV collagenase) is a matrix metallo-proteinase which degrades basement membrane collagens. Various studies emphasize its role in stromal invasion of cancers, but there is some controversy about its origin. Gelatinase A was localized by immunohistochemistry using confocal microscopy in 15 human mammary carcinomas. In addition, the cells responsible for the synthesis of this enzyme were detected by in situ hybridization. Most invasive and non-invasive tumour cells were labelled by immunohistochemistry. Of particular interest was the pattern observed in some pre-invasive areas. Gelatinase A was found in fibroblasts in close contact with pre-invasive tumour clusters. Confocal observation allowed a more precise localization of gelatinase A to the periphery of tumour clusters along the basement membranes and in peritumour fibroblasts. The malignant epithelial cells were negative by immunohistochemistry in these areas. By in situ hybridization, mRNAs encoding gelatinase A were detected only in fibroblasts in close contact with pre-invasive and well differentiated tumour clusters. These findings support the hypothesis that peritumour fibroblasts produce gelatinase A and that breast cancer cells may bind this enzyme to their cell surface and/or internalize it. [less ▲]

Hsp90 is a protein chaperone regulating the stability and activity of many signalling molecules. The requirement of Hsp90 activity in the NF-κB pathway has been recently reported by several authors using the Hsp90 ATPase inhibitor Geldanamycin (GA), an anti-tumour drug. Hsp90 inhibition blocks the synthesis and activation of the IKK complex, the major kinases complex responsible for IκBα phosphorylation on serine 32 and 36, a key step for its degradation and the nuclear translocation of NF-κB. However, the effect of GA on other IκBα kinases, including tyrosine kinases, is unknown. In the present study, we investigated the effect of GA on NF-κB activation induced by sodium pervanadate (PV), a tyrosine phosphatase inhibitor triggering c-Src-mediated tyrosine phosphorylation of IκBα. We reporte for the first time that GA inhibits PV-induced IκBα tyrosine phosphorylation and degradation. Using an in vitro kinase assay, we demonstrated that GA inhibits the activity of c-Src as an IκBα tyrosine kinase, but not its cellular expression. As a result, GA blocked PV-induced NF-κB DNA binding activity on an exogenous κB element and on the endogenous iκbα promoter, thereby inhibiting IκBα transcription. Finally, we demonstrated that, despite NF-κB inhibition, pre-treatment with GA does not potentiate PV-induced apoptosis. We conclude that c-Src requires Hsp90 for its tyrosine kinase activity, and its inhibition by GA blocks c-Src-dependent signalling pathways, such as NF-κB activation induced by sodium pervanadate. The effect of GA on PV-induced apoptosis is discussed in the light of recent publications in the literature. [less ▲]

The effect of residual fat hydrolysis upon the gelation of whey protein concentrate (WPC) was studied. Gelling properties of a commercial WPC and lipase-treated WPC were evaluated on the basis of least concentration endpoint gelation, penetration test, texture profile analysis and water-holding capacity. Heat treatment of lipase-treated WPC led to gels with the highest hardness, springiness, cohesiveness and water retention. Such transformed WPC could be advantageously used to help improve texture in formulated meat, bakery, and confectionery products. [less ▲]

Die Auseinandersetzung um die Existenz-Bedingungen und die territoriale Ausdehnung des Staates Israel steht seit Jahrzehnten im Zentrum des Nahost-Konflikts. Grundlegend für die Landfrage ist die Tradition von "Erez Israel", dem "Land Israel" als gottbestimmter, legitimierter Heimat der Juden. Auf diese für Religion, Geschichte und Kultur des Judentums zentrale Tradition beruft sich auch der heutige jüdische Staat. Er versteht sich als Erfüllung des Traums von der "Erlösung Israels". Die Proklamationsurkunde von 1948 erklärt das "natürliche und historische Recht des jüdischen Volkes", den jüdischen Staat "auf den Boden des Heimatlandes" zu gründen: in Palästina. Textzeugnisse unterschiedlicher Herkunft und Gattung aus der Zeit zwischen 600 v. Chr. bis 2000 n. Chr. dokumentieren die Idee von verheißenem Land und die Kopplung von Religion und Land in Tradition von "Erez Israel". Kommentare und Erläuterungen von Wissenschaftlern verschiedener Disziplinen liefern Hintergrundinformationen und einen historischen Überblick. Sie ermöglichen es dem allgemein-politisch wie dem fachwissenschaftlich interessierten Leser, sich ein eigenes Urteil zu bilden. [less ▲]
