objective: there is no definitive data on the strength of glass fiber and cast posts with different length. this in vitro study was designed to investigate and compare the effect of length on the retentive strength of glass fiber and cast posts. materials and methods: sixty recently extracted intact maxillary canine teeth were cut 1mm above the cej. the specimens were endodontically treated and...

Materials and methods This is a preliminary randomized study lead at the CMCR des Massues in Lyon since April 2010 to January 2011 about 40 teenagers treated by Abbott cast. First group (n=17) have had 3D analysis before cast and second (n=23) group after cast. With the 3D analysis we have worked out if the thoracic band was put by classical method or was conversely put (based on plane of maxim...

The Urban Heat Island (UHI) phenomenon prevalently concerns industrialized countries. It consists of a significant increase in temperatures, especially in industrialized and urbanized areas, in particular, during extreme warm periods like summer. This paper explores the climate variability of temperatures in two stations located in Matera city (Southern Italy), evaluating the increase in temper...

conclusions when evaluating flank pain in patients, it is important to remember that cbc parameters may support urinary stone disease, and considering cbc results may be useful in the diagnosis of urinary stone disease. patients and methods this study was a retrospective observational study of 3,099 patients who were admitted to the urology outpatient clinic or diagnosed with urinary stone dise...

Two forms of Ca2+-dependent cysteine proteinase (calpain, EC 3.4.22.17) and their specific endogenous inhibitor (calpastatin) were partially purified from porcine retina: calpain I (low-Ca2+-requiring form) was half-maximally activated at 8 microM-Ca2+, and calpain II (high-Ca2+-requiring form) at 250 microM-Ca2+. Both calpain I and calpain II were inhibited by calpastatin. Calpain I from porci...

This survey study investigated whether viewer perceptions of reality programs’ authenticity were associated with involvement, enjoyment, and perceived learning. Four dimensions of perceived authenticity were identified: cast eccentricity, representativeness, candidness, and producer manipulation. Perceptions that the cast was not eccentric, that they were representative of people the respondent...

Guy Desaulniers and Daniel Villenueve The problem considered involves finding the minimum cost path, with cost and time being two independent quantities that govern the shortest path. In this problem, each arc is associated with a cost of traversing the arc as well as the time required to traverse it and each node is associated with a lower bound and an upper bound on the time of departure from...

Installing stone columns in the ground is an effective improvement technique to increase the load bearing capacity and reduce the consolidation settlement of the loose or weak cohesive soils. In addition to the increase in the bearing capacity and reduction in the settlement, stone columns can accelerate the dissipation rate of the excess pore water pressure generated by the surcharge, which ex...
