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...

Background: Transfusion-transmi!ed infec"ons (TTIs) con"nue to be a problem in many parts of the world and mul"-transfused pa"ents are at a par"cularly increased risk for TTIs. The aim of this study was to determine the prevalence of Hepa""s C, Hepa""s B, and human immunodeficiency virus (HIV) infec"ons among mul"-transfused pa"ents in Khuzestan Province. Materials and Methods: A cross-sec"onal...

Background: Despite the known effects of inadequate physical activity (PA), adoption of appropriate interventions to increase PA is still problematic. The aim of this study was to identify and prioritize evidence-based strategies to increase women’s PA in the context of Iranian society. Methods: This is a mixed-method study. A systematic review of clinical interventions was used to stimulate a...

the present study investigates the possibility of using poloxamers as solubility and dissolution rate enhancing agents of poorly water soluble bioactive constituent patchouli alcohol (pa) that can be used for the preparation of immediate release pellets formulation. two commercially available grades poloxamer 188 (p 188) and poloxamer 407 (p 407) were selected, and solid dispersions (sds) conta...
