the application of chemotherapy in cancer treatment has been limited due to cause side effects such as toxicity against normal cells and drug resistance. in recent years, numerous studies have been focused on using natural products with chemotherapeutic drugs to enhance therapeutic efficiency and reduce cytotoxicity. on the other hand, encapsulation of drugs into nanoparticles (nps) can improve...

motivated by the recent study on categorical properties of latticevalued topology, the paper considers a generalization of the notion of topological system introduced by s. vickers, providing an algebraic and a coalgebraic category of the new structures. as a result, the nature of the category   topsys   of s. vickers gets clari ed, and a metatheorem is stated, claiming that (latticevalu...

A graph G is a Zm-well-covered graph if |I1| ≡ |I2| (modm) for all maximal independent sets I1 and I2 in V (G) [3]. The recognition problem of Zm-well-covered graphs is a Co-NP-Complete problem. We give a characterization of Zm-well-covered graphs for chordal, simplicial and circular arc graphs. c © 2001 Elsevier Science B.V. All rights reserved.

the activation of carbon monoxide by oxygen on mg(100) surface has been investigated by x-ray photoelectron spectroscopy (xps). carbon monoxide is only weakly adsorbed (dispersion-type forces) on a magnesium surface. the xps result has shown that the dissociation of carbon monoxide leading to the formation of a metastable surface carbonate species occurs through the participation of an oxygen s...

â â â â â  abstract: â  as the number of independent countries increases and their economies become more integrated, we would expect to observe more multi-country currency ::::union::::s. this paper explores the pros and cons for different countries to adopt as an anchor the us dollar, the euro or the yen. in addition, it addresses the question of how co-movement of outputs and prices would res...

air pollution in large cities is very important from health and economic points of views. in a city, air pollution has direct relationship with the topography, climate, population, economic situation and the degree of industrialization. therefore, for a survey about kerman's air pollution, 13 stations were chosen for determination of so2, no2 and co, and 14 stations to assess concentration of s...
