Background and Aims: Finishing and polishing of composites is a critical step influencing the clinical service of restorations. The aim of this article was to evaluate and compare the effect of two liquid polishes on the polish retention of two nanocomposites. Materials and Methods: Eighty standardized disk-shaped specimens (4×2 mm) were prepared from two nanocomposites (n=40), including one n...
In contrast to other mammalian reservoirs, many bat species migrate long-distances and have the potential to introduce exotic pathogens to new areas. Bats have long been associated with blood-borne protozoal trypanosomes of the Schizotrypanum subgenus, which includes the zoonotic parasite Trypanosoma cruzi, agent of Chagas disease. Another member of the subgenus, Trypanosoma dionisii, infects b...
in this study, we assess the impact of oil price changes on the macroeconomic variables of some oil importers in oecd countries, including usa, italian, france and japan during the period 1960-2002. the results for different countries imply asymmetric impact of oil price changes on gdp growth rates; moreover, the results show that monetary shocks are an important and noticeable factor explainin...
s) is all that is necessary. Cell biology, physiology, molecular biology, and biochemistry presentations centered around the theme of biological transport are all welcome. Presentations are made in an informal atmosphere with open discussion encouraged. The scientific sessions will be held morning and evening. Afternoons are free to enjoy swimming, fishing, golfing, riding, hiking, or just rela...
When, in 1784, the land surveyor Thomas Jefferson called into being the states of the so-called Northwest Ordinance by drawing lines on a map, his map was sufficiently inaccurate that it did not even have the Great Lakes in the right places. Ten states would nonetheless eventually be created in the area of Jefferson’s map, having boundaries which in large degree follow his original lines. These...
We show empirically using panel data at the plot and farm level and based on a model incorporating supervision costs, risk, credit-market imperfections and scale-economies associated with mechanization that small-scale farming is inefficient in India. Larger farms are more profitable per acre, more mechanized, less constrained in input use after bad shocks, and employ less per-acre labor than s...
Land cover maps reasonably depict areas that are strongly converted by human activities, but typically are unable to resolve low-density but widespread development patterns. Data products specifically designed to resolve land uses complement land cover datasets and likely improve our ability to understand the extent and complexity of human modification. Methods for developing a comprehensive la...
