Employee's performance and Kaizen events' success: does supervisor behaviour play a moderating role?
(Emerald, 2023-12-05)The study's goal was to identify the factors contributing to the practical completion of Kaizen events (KEs). The effect of the work-study man's characteristics, the supervisor's conduct and the autonomy of the Kaizen team ... -
Engineering a therapeutic lectin by uncoupling mitogenicity from antiviral activity
(Elsevier, 2015-10-22)A key effector route of the Sugar Code involves lectins that exert crucial regulatory controls by targeting distinct cellular glycans. We demonstrate that a¿¿single amino-acid substitution in a banana lectin, replacing ... -
Enhanced photostability of a Ruthenium(II) Polypyridyl Complex under highly oxidizing aqueous conditions by its partial inclusion into a cyclodextrin
(Wiley, 2016-01-08)The complex [Ru(bpy)2L]2+, where bpy=2,2′-bipyridine, L=4-(phenylethynyl)-2,2′-bipyridine, was prepared in its racemic and resolved forms (Δ and Λ). The phenylethynyl unit on the bipyridine for the complex acts as a binding ... -
Evaluating the interaction of human serum albumin (HSA) and 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) liposomes in different aqueous environments using anisotropy resolved multi-dimensional emission spectroscopy (ARMES)
(Elsevier, 2022-01-07)Studying the interaction between plasma proteins and liposomes is critical, particularly for their use as drug delivery systems. Here, the efficacy of anisotropy resolved multidimensional emission spectroscopy (ARMES) for ... -
Evaluation of acridine in Nafion as a fluorescence-lifetime-based pH sensor
(2003)We report a novel fluorescence-lifetime-based pH sensing method that utilizes acridine incorporated into Nation (AcNaf) as the fluorescent indicator. The AcNaf sensor is excited using a 380 nm light emitting diode (LED) ... -
Evaluation of non-ideal piston stopping effects on the “adiabatic core” and ignition delay time simulation in rapid compression machines
(Elsevier, 2020-05-30)Piston creep and rebound are two non-ideal piston stopping behaviors in the rapid compression machine. Compared to nominal piston stopping, piston rebound/creep will result in a smaller/bigger 'adiabatic' core zone volume ... -
An excitation emission fluorescence lifetime spectrometer using a frequency doubled supercontinuum laser source
(IOP Publishing, 2018-09-03)The accurate fluorescence analysis of complex, multi-fluorophore containing proteins requires the use of multi-dimensional measurement techniques. For the measurement of intrinsic fluorescence from tyrosine (Tyr) and ... -
