A compact Raman microprobe/microscope: Analysis of polydiacetylene Langmuir and Langmuir-Blodgett films

A compact Raman microprobe/microscope has been developed which contains no wavelength dispersive elements. Multilayer dielectric filters, tuned by rotation, provide sufficient wavelength selectivity for taking Raman spectra and forming Raman images of samples as small as 1 μm in diameter. The application of the instrument is demonstrated by Raman spectra and images of polydiacetylene Langmuir and Langmuir-Blodgett films.

Abstract of the 68th Meeting (Spring Meeting) 6–9 March 1990, Heidelberg

Formation of protein multilayers and their competitive replacement based on self-assembled biotinylated phospholipids.

Based on specific recognition processes the build-up of protein multilayers was achieved using streptavidin layers as a docking matrix. For this purpose, streptavidin was organized at biotin-containing monolayers, liposomes, and self-assembled layers on gold. Thus, mixed double and triple layers of streptavidin, Con A, Fab fragments, and hormones were prepared and characterized by fluorescence microscopy and plasmon spectroscopy. Using biotin analogues with lower binding constants several cycles of multilayer formation followed by competitive replacement could be achieved.

Die Therapie der veralteten Schulterluxation

Eine Schulterluxation, die langer als vier Wochen besteht, gilt als veraltet. Die Diagnose ist klinisch-radiologisch einfach zu stellen. Therapeutisch ist die Reposition auch nach Monaten noch anzustreben. Gelingt die Reposition nicht, ist lediglich bei jungen Patienten die blutige Reposition angezeigt. Bei alteren Patienten sollte der Zustand belassen und die eintretende Gebrauchsminderung in Kauf genommen werden.

New experimental efforts along the rp-process path

The level structure just above the proton threshold of the nucleus 30S has been studied using the neutron removal process on fast radioactive beams at the National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University. In this work we provide a description of the experimental setup. The present status of the analysis is also discussed.

Das Kiefergelenk bei entzündlichen, degenerativen und weichteilrheumatischen Erkrankungen

Temporomandibular joint affections in rheumatic disease are described. They were seen in inflamed joint diseases, mostly in rheumatoid arthritis, and less so in juvenile rheumatoid arthritis, psoriatic arthritis, Reiter’s syndrome, ankylosing spondylitis, and collagen vascular disease.

Improving the nuclear physics input along the rp-process path

The level structure of 30 S was studied at the NSCL by using neutron removal reactions with a radioactive 31 S beam. The γ -decay from excited states in 30 S was measured in a Ge-detector array. The results discussed for this work will reduce the uncertainties in the determination of the astrophysical 29 P(p, γ ) 30 S reaction rate under rp -process conditions.

Nucleosynthesis of proton-rich nuclei. Experimental results on the rp-process

Experience NSCL; International audience; We report in this study the nuclear properties of proton-rich isotopes located along the rp-process path. The experiments have recently been performed at the National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University. The level properties above the proton separation energy of the nuclei 30S, 36K and 37Ca were measured with precision of < 10 keV. This will allow a reduction in the determination of the astrophysical (p, ) reaction rate under rp-process conditions.
