Sensitivity analysis of the secondary heat balance at Koeberg Nuclear Power Station
… most important being the Secondary Heat Balance (SHB) test which has been programmed within the central Koeberg computer and data processing system (KIT). Improved accuracy in the SHB will result in a more accurate representation of the thermal power generated in the core. The input variables have …

Investigating the morphological adaptations and fungal associations of the small hive beetle, Aethina tumida Murray (Coleoptera: Nitidulidae)
… Aethina tumida Murray (Coleoptera: Nitidulidae) (SHB) acts as a facultative hive pest of the western honey bee, Apis mellifera L. (Hymenoptera: Apidae). Drawn to honey bee hives by volatiles from the yeast Kodamaea ohmeri (Ascomycota: Saccharomycotina), the beetles must avoid injury from the …

Studies on the Structure and Pathogens of the Small Hive Beetle (Coleoptera: Nitidulidae)
<p>The small hive beetle (Aethina tumida, SHB) is an invasive pest of honey bee (Apis mellifera) colonies in the United States. The adult and larval beetles can ruin honey through fecal contamination and by vectoring a mutualistic yeast (Kodamaea ohmeri) that causes honey fermentation. These …

Ultrasound-encoded optical tomography and time-reversed ultrasonically encoded optical focusing
… photons. We also applied spectral-hole burning: SHB) aided detection in ultrasound-modulated optical tomography: UOT) to image optical heterogeneities in thick tissue-mimicking phantom samples and chicken breast tissue. The efficiency of SHB was improved by using a Tm3+: YAG crystal of higher …

Drivers of short-term variability in phytoplankton production in an embayment of the southern Benguela upwelling system: an observational and modelling study
… levels of primary productivity. St Helena Bay (SHB), a coastal embayment in the SBUS positioned north of an upwelling centre, is an area of water mass retention. In addition to supporting 40-50% of total SBUS productivity, SHB often experiences harmful algal blooms (HABs) and hypoxic conditions …

Role of the interaction of proHB-EGF with heparan sulfate proteoglycans
… (autocrine/paracrine) form of the protein (sHB-EGF), produced after proteolytic cleavage of the transmembrane form (proHB-EGF) from the cell surface. It was hypothesized that HSPGs interact with proHB-EGF in ways that could alter behavior of the transmembrane form of this ligand and …

Theoretical study of performance characteristics of semiconductor quantum dot lasers
… 3) Effect of longitudinal spatial hole burning (SHB) and multimode lasing on the LCC. The number of modes is shown to remain limited with increasing injection current. The maximum number of modes that can oscillate in a QD laser is analytically estimated. While this number increases with …

Wasserstoffatomdynamik in Radikalen, Clustern und Biomolekülen
Die Untersuchung der molekularen Dynamik elektronisch angeregter Moleküle stand im Zentrum dieser Arbeit. In vielen Fällen ist die Dynamik dieser Zustände mit einer Bewegung von Wasserstoffatomen assoziiert. Mittels zeit- und frequenzaufgelöster Photofragmentspektroskopie lassen sich Aussagen über …
