Optical and gamma-ray study of gamma-ray binaries
Gamma-ray binary stars are intriguing interacting stellar systems that exhibit emission across the whole electromagnetic spectrum. This thesis is focused on optical and gamma-ray emission of gamma-ray binary stars (GRBis). I have performed radial velocity measurements of 1FGL J1018.6-5856 to derive …

Selective Gamma Substitution of Alpha-Trimethylsilyl-Beta,gamma-Unsaturated Esters
… in order to synthesize (alpha)-silyl-(beta),(gamma)-unsaturated esters. Although a nickel-catalyzed coupling reaction of vinyl bromides with lithium ethyl (alpha)-trimethylsilylacetate was employed to synthesize those esters utilized in subsequent reactions, an alternative method, viz. …

Cobalt stabilized gamma-chloroalkynones and alkynoates as gamma-carbonyl cation synthons.
$\gamma$-Cationic-$\alpha,\beta$-unsaturated carbonyl synthons have been prepared via hexacarbonyldicobalt complexed $\gamma$-chloroalkynoates and alkynones (100). Treatment of 100 with silver salts in the presence of silyl enol ethers (102-104) generated 2-alkynyl-1,6-dicarbonyl compounds …

Signaltransduktion der gamma-Protocadherine
Gamma-Protocadherine (gamma-pcdh), glykosilierte Typ I Transmembranproteine mit einer extrazellulären Domäne aus sechs Cadherin-artigen Modulen, sind vermutlich an Zelladhäsion beteiligt und in Säugetieren überlebensnotwendig. In der Maus gibt es 22 gamma-pcdh-Isoformen, deren Ektodomäne, …

SKIN COMMENSAL STAPHYLOCOCCUS PROMOTES SYSTEMIC V-GAMMA-6 GAMMA-DELTA T CELL RECONFIGURATION
The gut microbiota is known to regulate both local immune responses and systemic functions in healthy hosts. However, it remains unclear whether the skin microbiota – resident on the body's largest barrier – can influence systemic responses. Skin-resident Staphylococcus aureus is a common commensal …

Metallographic study of gamma - gamma prime structure in the Ni-based superalloy GTD111
… can be attributed to a large extent, to the gamma prime ([gamma]') precipitates found within the FCC [gamma]-matrix. Service-induced material degradation mainly involves coarsening and shape transformation of [gamma]'-phase precipitates; therefore, any bucket repair attempt should primarily …

Measurement of the Partial Widths Ratio Gamma(Ds*+ -> Ds+ pi0) / Gamma(Ds*+ -> Ds+ gamma) at the BABAR Experiment
… Zerfälle Ds*+ -> Ds+ pi0 und Ds*+ -> Ds+ gamma mit zwei verschiedenen Methoden rekonstruiert. Die Rekonstruktions-Effizienzen wurden mittels Signal-Monte Carlo-Ereignissen und D*0-Zerfällen ermittelt. Auf diese Weise wurde das Partialbreiten-Verhältnis Gamma(Ds*+ -> Ds+ pi0) / …

Beta-gamma-gamma correlation in Mn[superscript 56] : a test of time reversal invariance
… to measure time reversal violation in two beta-gamma-gamma cascades of Mn (2.58 h) is discussed. We show how one measures the interference terms in ft-Y-o correlations using experimental quantities. We explain in detail the systematic errors involved in an accurate correlation experiment and …

Beta-Gamma Directional Correlation Measurements
… show a definite correlation with ->k1. In beta - gamma angular correlation studies a radioisotope emits in rapid succession a beta particle followed by a gamma-ray. The relative probability that the gamma-ray is emitted into the solid angle of a movable detector at an angle theta with respect to a …

The measurement of gamma ray-induced heating in a mixed neutron and gamma ray environment
The problem of measuring the gamma heating in a mixed DT neutron and gamma ray environment was explored. A new detector technique was developed to make this measurement. Gamma heating measurements were made in a low-Z assembly irradiated with 14-MeV neutrons and (n,n$\sp\prime$) gammas produced by …
