Abstract: Power system stabilizers (PSSs) are widely used for suppressing low frequency oscillations in practical power systems. However, according to the requirement of the “guide for setting test of power system stabilizer” of China, PSS gain is limited to no more than 1/3 of its critical gain. As a result, PSSs may not provide enough damping to the inter-area mode oscillations. Through analy...

Recent research has emphasized the importance of workshops as a venue where planning support systems (PSS) are used in planning processes. Empirical studies of these workshops have previously largely overlooked facilitation, in particular the role of a moderator (steering the discussion) and/or a chauffeur (steering the PSS). Drawing on existing facilitation research, we identify four main cate...

Cough is a common presenting symptom of interstitial lung disease (ILD). The aim of this study was to examine the cough reflex in patients with progressive systemic sclerosis (PSS), with and without associated ILD. The cough reflex to inhalation of chloride deficient solutions and capsaicin was determined in patients with PSS with associated ILD (n=12), compared to patients with PSS without ILD...

Mushrooms are widely distributed around the world and are heavily consumed because of their nutritional value and medicinal properties. Polysaccharides (PSs) are an important component of mushrooms, a major factor in their bioactive properties, and have been intensively studied during the past two decades. Monosaccharide composition/combinations are important determinants of PS bioactivities. T...

INTRODUCTION This study examined the effect of endurance exercise on dendritic arborization in the dentate gyrus subregion in rodents exposed to a predator scent stress (PSS). METHODS Sprague-Dawley rats were randomly assigned to one of four treatment groups. In two of the groups, rats were unexposed to PSS but either remained sedentary (SED + UNEXP) or were exercised (EX + UNEXP). In the oth...

OBJECTIVE This study aimed to assess the association between perceived social support (PSS) and fatigue and the roles of hope, optimism, general self-efficacy and resilience as mediators or moderators on PSS-fatigue association among Rheumatoid Arthritis (RA) patients in China. METHODS A multi-center, cross-sectional study was conducted withinpatients diagnosed with RA in northeast China, in ...

Objective To define the presence and relationship of the petrosquamous stalactite (PsS)-a condensation of the trabecular Korner's septum into a bony plate of the petrosquamous suture-to surrounding structures and understand its surgical implications. Study Design Series of cadaver dissections. Setting University of Missouri Alumni Temporal Bone and Microvascular Laboratory. Subjects and Methods...

A sensitive capsaicin sensor was constructed based on a poly(sodium 4-styrenesulfonate) functionalized graphite modified screen printed electrode (PSS-Grp/SPE) in this study. The PSS-Grp and poly(diallyldimethylammonium chloride) functionalized graphite (PDDA-Grp) were easily synthesized by interacting Grp with PSS and PDDA through sonication, and resulted in negative and with positive charges ...

PURPOSE We determined if and to what extent longitudinal changes in lower urinary tract symptoms are related to disease specific and generic quality of life in men. MATERIAL AND METHODS A longitudinal, population based study with a followup of 4.2 years was done in 1,688 who were 50 to 79 years old. Data were collected through self-administered questionnaires, including the Sickness Impact Pr...
