statement of the problem: although all-ceramic restorations are broadly used, there is a lack of information concerning how their fit is affected by fabrication procedure and marginal configuration. purpose: the purpose of this study was to evaluate the marginal fit of zirconia cad/cam ceramic crowns before and after porcelain firing. the influence of finish line configuration on the marginal f...

Recently, the quality and safety of organic products is the topic of prime concern. While this demand increases since consumer considers organic products are healthier and harmless than conventional products. In the country like India, organic agricultural is not novel and are effectively performs in varied climates such as tribal mountains, mountainous areas and rain-fed zones of the country. ...

In many implemented network revenue management systems, a bid price control is being used. In this form of control bid, prices are attached to resources, and a product is offered if the revenue derived from it exceeds the sum of the bid prices of its consumed resources. This approach is appealing because once bid prices have been determined, it is fairly simple to derive the products that shoul...

The establishment of cell and tissue polarity during animal development often requires signaling by Wnts, extracellular signaling polypeptides. Transmembrane receptors of the Frizzled family are implicated in the transduction of Wnt signals in responding cells. Xfz8 is a novel cDNA encoding a Xenopus homologue of mouse Frizzled 8. Xfz8 transcripts are expressed zygotically in the organizer at t...

Over the past thirty years, economists have become increasingly interested in the labor market for professional sports. These studies have focused primarily on exploitation, the difference between marginal revenue product and salary, or discrimination, salary differentials based on race, or ethnic background. This paper attempts to combine both areas of research. that is, to explain the systema...

OBJECTIVE The objective of this randomized, single-use, single-blind, two-group, parallel clinical trial was to evaluate the supragingival plaque removal efficacy of two power interdental devices combined with a manual toothbrush. METHODS Eighty-two (82) subjects completed the study. Subjects were randomly assigned to one of two groups: Waterpik Water Flosser (WF) plus manual tooth brushing o...

This study focuses on how an upstream supplier signals the private information of its product quality with corporate social responsibility (CSR) choices to a downstream retailer and uninformed consumers in the final market. We build a signaling model to: capture the strategic interactions among the supplier, the retailer, and the final consumers in the supply chain; characterize completely the ...

Arithmetic circuits have been used as tractable representations of probability distributions, either generated from models such as Bayesian networks, sum-product networks and Probability Sentential Decision Diagrams, or directly from data. An interesting question is how we can incorporate uncertain evidence, which specifies that the marginal probabilities of a variable has to undergo certain ch...

purpose: the aim of this study was to evaluate the effect of two gingival finishing lines (90° shoulder and deep chamfer) on the marginal fitness of two types of full anatomic all-ceramic crowns; zirconia crowns (zikonzhan) and glass ceramic crowns (ips e-max cad) milled with cad/cam system. materials and methods: two dentoform teeth of left maxillary first molar were prepared with chamfer fini...

This paper presents an easily understood example of a labor market that is useful in introducing how wages and rents are determined, using professional baseball as the context. The mechanics of a competitive labor market are outlined and an empirical analysis of the major league baseball (MLB) labor market is described. An example out-of-class exercise investigating whether baseball player sala...
