objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
Changes in black tea quality were studied for three subsequent years and in different times of plucking (spring, summer and autumn) in the form of two leaves and a bud. Percentage of waste, total sensory scores, total soluble solid, caffeine, theaflavin, thearobigin, total color and brightness were evaluated in black tea. The data were analyzed in split plot design based on randomized complete ...
This article presents a simplified model for studying the main parameters for magnetically plucking piezoelectric beams in energy harvesting devices. The advantage of magnetic plucking is that there is no impact on the brittle piezo material. However, achieving a good release of the piezo beam is more difficult than with fingers or plectra. The influence of different magnet arrangements, the ga...
this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
Background: To refine an on-hen mite feeding device, ethogram was employed to measure the reactions of hens during a routine experimental procedure (feather plucking) and assess effects analgesic cream on those reactions. Methods: Three groups were used; one treated with EMLA 5% before plucking (“EMLA group”); ...
More than thirty years ago Milton Friedman proposed a `plucking' model of business °uctuations in which output cannot exceed a ceiling level, but will, from time to time, be plucked downward by recession. The model implied that business °uctuations are asymmetric, that recessions have only a temporary e®ect on output, and that recessions are duration dependent while expansions are not. Subseque...
