5 A plot of log log antheridial hyphae vs. log concentration of A2 reveals a linear relationship. From this it follows that I = e' , where I is reaction intensity, x, the concentration of A2 and k, a proportionality constant. The author wishes to thank Dr. Leonard J. Savage for pointing out this relationship. 6 An alternate interpretation of A2 activity might be that the water-soluble fraction ...

A multiwall carbon nanotubes-modified carbon paste electrode (MWCNTs/MCPE) wasfabricated and used to study the electrooxidation of penicillamine (PA) by electrochemicalmethods in the presence of methyldopa (MDOP) as a homogeneous mediator. Theelectrochemical oxidation of PA on the new sensor has been carefully studied. The kineticparameters such as electron transfer coefficient, α, and catalyti...

I love PA Week. There is such a sense of excitement and pride as the profession acknowledges the past, celebrates the present, and looks to our future. My fi rst week in physician assistant (PA) education culminated in a Duke University PA Day celebration. I still remember these festivities 13 years later because it was the fi rst time I really thought about the history of the profession and th...

PA (Process algebra) is the name that has become common use to denote the algebra with a sequential and parallel operator (without communication), plus recursion. PA-processes subsume both Basic Parallel Processes (BPP) Chr93] and context-free processes (BPA). They are a simple model for innnite state concurrent systems. We show that the model checking problem for the branching time temporal lo...

iii Summary This master thesis describes the development of a new type RF PA and upconverter combination. Instead of the normally used voltage steering the amplifier uses charge steering. The parasitic capacitances of the MOSFET in combination with using charge steering form a feedback network that linearizes the amplifier. The developed device is a switching amplifier. For good behavior it use...

To reduce a large number of variables to a smaller number of factors for modeling purposes, where the large number of variables precludes modeling all the measures individually. As such, factor analysis is integrated in structural equation modeling (SEM), helping confirm the latent variables modeled by SEM. However, factor analysis can be and is often used on a stand-alone basis for similar pur...
