A PC-based instrument for automatic monitoring and control of a CPVT power plant

2014

A PC-based instrument has been developed for the monitoring and control of a concentrated photovoltaic and thermal (CPVT) power plant. The instrument allows acquiring both electrical and thermal quantities. Moreover it implements the solar tracking algorithm used to optimize the power production.

The effects of antimicrobial sprays and mouthrinses on supragingival plaque regrowth: a comparative study.

2006

BACKGROUND: Due to the side effects of chlorhexidine digluconate (CHX) mouthrinsing, a spray has been proposed as an alternative method of CHX delivery to the oral cavity. The aim of this study was to investigate the plaque inhibitory effects of CHX, cetylpyridinium chloride (CPC), and triclosan (TRN) delivered by sprays and mouthrinses. METHODS: The study was an observer-masked, randomized cross-over design balanced for carryover effects, involving 15 healthy volunteers in a 4-day plaque regrowth model. Products being tested (0.2% CHX, 0.12% CHX, 0.05% CPC, and 0.03% TRN) were used both as sprays and mouthrinses. A saline solution served as a negative control. On day 1, subjects received p…

Discussions of Fatherhood in Male Batterer Treatment Group

2013

The aim of this study was to examine how men who have perpetrated violence toward their partners and participated in batterer group talked about being a father and how they perceived their own fatherhood. The discussion in the group was analyzed qualitatively by using the methods of content analysis. In traditional fatherhood, they talked about avoidant, passiveness, distant, indifference, and authoritative controlling ways of acting. These men also created an image of themselves as active and caring fathers, thus including empathy and nurture in the concept of fatherhood. This new fatherhood was considered an achieved goal and an objective for the men as being a father. Talking about fath…

Regularity for nonlinear stochastic games

2015

We establish regularity for functions satisfying a dynamic programming equation, which may arise for example from stochastic games or discretization schemes. Our results can also be utilized in obtaining regularity and existence results for the corresponding partial differential equations. peerReviewed
