The goal of this thesis is achieving saturation intensity of 76.5 mW/cm2for 2S1/2F=1 - 2P1/2F = 2 transition in singly-ionized beryllium ions (Be+). By enlarging the optical power of a laser diode at 626.266 nm via a bow-tie cavity and converting to 313.133 nm using Second Harmonic Generation in a nonlinear …

To obtain a unified framework for symmetric and asymmetric heterotic orbifold constructions we provide a systematic study of Narain compactifications orbifolded by finite order T -duality subgroups. We review the generalized vielbein that parametrizes the Narain moduli space (i.e. the metric, the B-field …

This chapter concerns itself with the way in which China uses mainly non-kinetic means to broaden its power and influence in the South China Sea. The old writings of Sun Tzu and the modern writings of Liang and Xiangsui, together with the analysis of the tensions in the South China Sea, demonstrate that …

'Bestaat er een prothese-enkel of prothesevoet die zo ver in te stellen is of verend is dat deze voor zowel snowboarden, bergwandelen als zwemmen te gebruiken is? Zo niet, is het mogelijk een prothese-enkel te maken die dit wel kan?' Deze vraag kwam vanuit Anvasport Anvasport (2009). Het onderzoek vond …

The title compound, C24H16N2O8, is a twofold symmetric ether with two acetyl groups attached to the O atoms of the 1,1′-bi-2-naphthol. The molecular structure confirms that the nitro substituents are at the 6,6′ positions.
