Hydrodynamic Shock Wave: Decreasing Broiler Breast Aging Time
The Hydrodyne process was used to tenderize early de-boned broiler (EB) breasts. The first objective was to determine effects of explosive and distance of the explosive to the meat surface. EB breasts were removed immediately after initial chill (45 min post-mortem), stored for 24 hours, and …

Regulation of Wingless secretion, distribution and signaling
… Wg/Wnt signalling, the hyperplastic discs (hyd). Further epistasis analysis indicates that hyd acts in parallel with or downstream of Armadillo (Arm) to regulate nuclear Arm activity. Taken together, this dissertation work will help us to better understand the orchestrated regulation of …

Dimethyl N-Aryl phosphoramidates : structural effects on bonding and solvolytic reactivity
The acid catalysed hydrolysis of a number of ring alkyl substituted dimethyl N-aryl phosphoramidates, (MeO)2P(0)NHAr, has been studied by measuring the rates of hyd~olysis with the aid of a UV spectrophotometer. These rates have been correlated with the pKa values of the corresponding ani I inium …

Biohydrogen as a Fuel: Understanding and Engineering Hydrogenase Enzymes for Biotechnological Applications
Molecular hydrogen (H2) is seen as an ideal replacement for fossil fuels; however the current methods of its synthesis are unsustainable and environmentally damaging. Research is therefore needed to devise new, more suitable modes of H2 derivation. Biohydrogen – i.e. H2 derived from cellular …
