INTRODUCTION Candida Albicans (CA) is by far the most common yeast of oral infections, including endodontic infections. The aim of this study was to evaluate and compare the antifungal effect of white-colored mineral trioxide aggregate (WMTA) and Portland Cement (PC) using a tube-dilution test. MATERIALS AND METHODS WMTA and PC were tested freshly mixed and after 24 h. The experiment was perf...

In the recent years, resource depletion of inshore and coastal fisheries has seriously impacted Taiwan. Local fishing communities’ economic profits in these fisheries have declined and resulted in lower earned incomes for the fishermen. These phenomena have lead many scholars, government agencies and fishing communities to evaluate the optimal number of operating vessels in these fisheries. Thi...

This study examines the company internal factors and macro-economic variables affecting stock prices in the Karachi Stock Exchange of Pakistan. Internal factors are earnings per share and dividend per share. The macro-economic variables are represented by the money supply, consumer price index, interest rates, and gross domestic product. A sample of 15 companies is selected from the financial s...

Critique of Information is an important book of social theory that deserves a wide audience among students of media and society, although its dense conceptual structure and style of argument may challenge readers. It will certainly send them reaching for their copies of earlier work by McLuhan, Bell, Habermas, Giddens, Luhmann, Deleuze and Guattari, Lefebvre, Latour, Haraway, Poster, Luke, and ...

An initial zonally symmetric quasigeostrophic potential vorticity (PV) distribution qi( y) is subjected to complete or partial mixing within some finite zone jyj , L, where y is latitude. The change in M, the total absolute angular momentum, between the initial and any later time is considered. For standard quasigeostrophic shallow-water beta-channel dynamics it is proved that, for any qi( y) s...

In this work, I address the issue of forming riskless hedge in the continuous time option pricing model with stochastic stock volatility. I show that it is essential to verify whether the replicating portfolio is self-financing, in order for the theory to be self-consistent. The replicating methods in existing finance literature are shown to violate the self-financing constraint when the underl...

We introduce a new stable range condition and investigate the structures of rings with many idempotents. These are also generalizations of corresponding results of J. Stock and H. P. Yu.

Using a collection (n = 12) of ATCC and known stock isolates, as well as 328 clinical stool specimens, we evaluated the ESwab and the new FecalSwab liquid-based microbiology (LBM) devices for storing and transporting diarrheagenic bacteria. The stock isolates were stored in these swab devices up to 48 h at refrigeration (4°C) or room (∼25°C) temperature and up to 3 months at -20°C or -70°C. Wit...

Differences in rooting ability of birch (Betula pubescens J.F. Ehrh.) cuttings were observed as a result of differences in genotype and physiology of the stock plants. The uniformity in response among cuttings from micropropagated plants compared with cuttings from seed plants confirmed the advantage of using micropropagated plants to study environmental effects. Shoot morphology of the seed st...

Shareholders are the owners of listed companies, and their relationships can directly affect the structure of the stock market. In this paper, we analyze the topological properties and evolution of the cross-shareholding networks of listed companies in the past 5 years in China from 2007 to 2011, an infrequently considered topic, by taking shareholders’ cross-shareholding relationships into acc...
