OBJECTIVES The aim of this in vitro study was to evaluate the influence of different light curing units and modes on microleakage of flowable composite resins. METHODS Eighty Class V cavities were prepared in buccal and lingual surfaces of 40 extracted human premolars with cervical wall located in dentin and the occlusal wall in enamel. These teeth were randomly assigned into two groups (n=20...

Objectives were to test the effect of a lowsodium curing solution on processing characteristics of hams from purebred Berkshire pigs that were fed a step-up ractopamine HCl (RAC) feeding program or a negative control diet. Sixty pairs (n = 120) of hams were selected from two blocks of purebred Berkshire pigs (n = 200) that were fed either a control diet or 7.4 mg of ractopamine/ kg of diet for ...

Amongst the theoreticians there was a subspecies who interacted with experimentalists — these theorists tried to make sure that their ideas were testable and that someone tested them. Preeminent amongst these was Francis Crick who wrote all the quotes above shown in red italics (taken from Crick’s autobiographical book What Mad Pursuit: A Personal View of Scientific Discovery; Basic Books, New ...

In this paper we introduce Bezier Lights, an intelligent lighting system that allows users to intuitively establish virtual boundaries in indoor environments. Boundaries can be easily created/modified by arranging the layouts of disk-shaped devices (“stones”) on the building floor. The immediate purpose of the system is to assist users in incorporating location-aware capabilities into private p...
