introduction: open-apex teeth with irreversible pulpitis require complex and difficult treatment. providing the right environment for apexogenesis and pulp protection is vital for their long term prognosis. the young pulp of open apex tooth, however, is better equipped against irritation and assault. the aim of this study was to evaluate pulp inflammation in open apex canine teeth of cats. mate...

We established a model based on the “Malmquist index” to evaluate dynamic performance of scientific and technological innovation in seven Chinese universities, which included five categories: changes pure technical efficiency, production technology, scale organizational management performance, comprehensive efficiency. Seven domestic first-class universities were studied, empirical analysis was...

From a set of thirteen cataclysmic binaries that were discovered in the Swift Burst Alert Telescope (BAT) survey, we conducted time-resolved optical spectroscopy and/or time-series photometry of eleven, with the goal of measuring their orbital periods and searching for spin periods. Seven of the objects in this study are new optical identifications. Orbital periods are found for seven targets, ...

Most corals in tropical localities broadcast their gametes into the water column, yet we have a poor understanding of what forces reproductive schedules. Moreover, recent studies show considerable geographical variation in the duration of the coral spawning season. For example, on the Great Barrier Reef, corals display tight coupling, while corals in Kenya spawn over seven months. This study re...

In a review of the medical and social aspects of shift work Taylor (1970) points out that many of the most important questions relating to shift work remain to be answered. One of these questions, on which evidence to date has been almost nonexistent, is the effect of a twelve-hour shift system on absence attributed to sickness. An opportunity to examine this occurred in 1973 when a change was ...

We show that US consumer inflation expectations are formed using a variant of adaptive expectations proposed by Mankiw et al. (2004). In particular, expectations behave differently when food and energy prices rise sharply relative to other prices. Using the recently proposed test of Homm and Breitung (2012), we analyze the 1982–2010 period and identify seven periods where the headline price ind...
