We construct a random matching model to study the effects of clearing arrangements for private money on the prices at which private monies trade, the volume of exchange, and welfare. In a model with full information, clearing arrangements eliminate discounts on private monies issued in other locations, the volume of exchange increases, and welfare increases. However, with private information ab...

Clearing and labeling techniques for large-scale biological tissues enable simultaneous extraction of molecular and structural information with minimal disassembly of the sample, facilitating the integration of molecular, cellular and systems biology across different scales. Recent years have witnessed an explosive increase in the number of such methods and their applications, reflecting height...

root fracture injuries affect up to 7% of permanent teeth. this type of injury is rarely seen in teeth with open apices and depending on the fracture site, the prognosis is good. this case report describes a horizontal intra-alveolar root fracture in the middle third of a maxillary central incisor associated with an extrusive luxation of the coronal segment and its treatment in a 6-year-old gir...

although esthetic is a relative issue, depending upon the country and culture, almost all around the world, there is a consensus that a beautiful set of teeth is the one which is white and bright and is aligned regularly. in iran also the main feature of a beautiful tooth is its whiteness. during the past decades and centuries, tooth discoloration was considered as an esthetic issue and differe...

o bjectives: correct determination of working length is an important step for suc- cess of endodontic therapy. conventional radiography has limitations in providing the accurate location of apical foramen. for this reason, electronic apex locators (eals) were developed to shorten the treatment time and decrease the radiation dose. the aim of this study was to evaluate the accuracy of root zx ea...

Part of the optical clearing study in biological tissues concerns the determination of the diffusion characteristics of water and optical clearing agents in the subject tissue. Such information is sufficient to characterize the time dependence of the optical clearing mechanisms—tissue dehydration and refractive index (RI) matching. We have used a simple method based on collimated optical transm...

The importance of plasma lipoproteins in normal and abnormal fat metabolism has stimulated interest in the heparin-induced lipemia clearing system first observed by Hahn (2). As a result of the efforts of several independent investigators (3,4), it is now known that,, upon the administrat’ion of heparin to animals of many different species, an enzyme appears in the blood which is able to “clear...

Objective. Evaluation of the efficacy of Crest Herbal Crystal Toothpaste in "clearing internal heat." Methods. This was a randomized, double-blind, controlled parallel design clinical test of a product that was already on the market. 72 subjects were randomly assigned to control group (group A with Colgate Herbal Salty Toothpaste) or treatment group (group B with Crest Herbal Crystal Toothpaste...

Other substances, in addition to the heparin clearing factor, exert a plasma-clearing effect under experimental conditions. A mucin compound extracted from the pig gastric mucosa has recently been included among such substances. Its clearing effect, as evaluated by variations in plasma optical density, is as constant and evident as that of heparin, both in normal and atherosclerotic subjects un...
