The University of Duisburg-Essen is a public university in Duisburg and Essen, North Rhine-Westphalia, Germany and a member of the newly founded University Alliance Metropolis Ruhr. It was founded in 1654 and re-established on 1 January 2003 as a merger of the Gerhard Mercator University of Duisburg and the University of Essen. Until 1994 the name of the Gerhard Mercator University was Comprehensive University of Duisburg.With its 12 departments and more than 39,000 students, the University of Duisburg-Essen is among the 10 largest German universities. Many international students study at the University of Duisburg-Essen and give the cities of Duisburg and Essen an international atmosphere. Wikipedia.

For the simplified construction of a dispenser (10) for substances, comprising an outer casing (13) with a deformable outer wall (12), which encloses a deformable container arrangement (11), and also comprising at least one equalizing valve (23) for equalizing air, wherein an air-filled interspace (14) is provided between the outer wall (12) and the container arrangement, and substances are discharged once the outer casing (13) has been subjected to pressure, it is proposed that the container arrangement should have at least two containers (11 a, b) for the separate storage of liquid or pasty substances. For the long-term storage of said substances, in particular the exit region of the container arrangement (11) has a diffusion seal, in particular made of metal, which, just prior to the dispenser (10) being used, is pierced, and opened, from the dispensing head (15), in particular using spikes.

An onboard unit (OBU) for recording the kilometres travelled by a vehicle on a toll road includes a GPS module (17) for running calculation of the vehicle position and the route travelled, a communication unit (23) for communication with a control device (31), and a computer unit with a processor (19) and a memory (15). The computer unit is connected to the GPS module (17), the communication unit (23), and the memory (15). A program (13) and data, such as OBU-ID and vehicle master data, are stored in the memory (15) of the OBU. In addition, the geographic coordinates of a plurality of control polygons, the distance thereof to other control polygons, and the corresponding measured routes, are also stored in the memory (15). The control polygons additionally function to determine whether road segments subject to tolls have been travelled. A travelled route or measuring section is, however, only counted if the result is plausible, i.e. an independent route measurement substantially corresponds to the polygon distances. It is also important that the routes are calculated on the basis of the officially determined measured street segment.

An anti-CEACAM1 antibody includes at least one antibody heavy chain (V_(H)) domain having antigen binding sites CDR1^(H), CDR2^(H )and CDR3^(H), and at least one antibody light chain (V_(L)) domain having antigen binding sites CDR1^(L), CDR2^(L )and CDR3^(L). The antigen binding site CDR2^(H )has a sequence homology of at least 80% to the amino acid sequence WINTYTGEPT (SEQ ID No. 21).

The invention relates to a method for holding fish or other species which live in the water in a circulation system (1) comprising at least one holding tank (2), at least one biological filter (3), and optionally other water treatment units (4) for example for a supply of oxygen (5), for sterilization (6), for defoaming (7), for a mechanical filtering process (8), etc. The invention additionally relates to a circulation system. In order to reduce the energy requirement, supply air is supplied to the system by at least one supply air line (60), and exhaust air is discharged by at least one exhaust air line (59). Supply and exhaust air is conducted through a heat exchanger in which heat contained in the exhaust air is transferred to the supply air, and/or the temperature of the supply air is increased to the level of the holding basin.

Surface-enhanced Raman scattering (SERS) has become a mature vibrational spectroscopic technique during the last decades and the number of applications in the chemical, material, and in particular life sciences is rapidly increasing. This Review explains the basic theory of SERS in a brief tutorial and - based on original results from recent research - summarizes fundamental aspects necessary for understanding SERS and provides examples for the preparation of plasmonic nanostructures for SERS. Chemical applications of SERS are the centerpiece of this Review. They cover a broad range of topics such as catalysis and spectroelectrochemistry, single-molecule detection, and (bio)analytical chemistry. Expanding vibrational spectroscopy: Since its first observation in 1973, surface-enhanced Raman scattering (SERS) has developed into a mature vibrational spectroscopic technique. The number of applications in chemistry as well as the material and life sciences is increasing rapidly. This Review summarizes the key concepts behind SERS and provides an overview of current applications in chemistry. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Myocardial infarct size is a major determinant of prognosis. Ischaemic preconditioning with brief coronary occlusion and reperfusion before a sustained period of coronary occlusion with reperfusion delays infarct development. Ischaemic postconditioning uses repetitive brief coronary occlusion during early reperfusion of myocardial infarction and reduces infarct size. Remote ischaemic preconditioning uses brief ischaemia and reperfusion of a distant organ to protect the myocardium. These conditioning protocols recruit a complex signal cascade of sarcolemmal receptor activation, intracellular enzyme activation, and ultimately mitochondrial stabilisation and inhibition of death signalling. Conditioning protocols have been successfully used in patients undergoing elective coronary revascularisation and reperfusion after acute myocardial infarction. Pharmacological recruitment of cardioprotective signalling has also been used to reduce infarct size, but so far without prognostic benefit. Outcomes of cardioprotection are aff ected by age, sex, comorbidities, and drugs, but also by technical issues related to determination of infarct size and revascularisation procedure.

An extensive review covering all aspects of Calcium-mediated reactions, which include application of calcium compounds as homogeneous catalysts, is presented. Considerable contributions is made to an understanding of Schlenk equilibria in organocalcium chemistry and it is found that the stability of heteroleptic calcium complexes depend on temperature, concentration, presence of polar (co)solvents, amd ligand bulk. Studies also found that the homoleptic complex of calcium is fast in ε-CL polymerization and slow in the polymerization of L-lactide. Investigation of calcium catalysts based on Schiff base ligands shows that polymerizations are initiated either by a salen-Ca complex or by well-defined single-site catalysts. Successful use of organocalcium species as initiators for syndioselective and living styrene polymerization can be attributed to the right balance of Lewis-basic and Lewis acidic properties.
