In this research, we analyze the evolution of the international air transportation country network from 2002 to 2013 with two perspectives: The network’s physical topology and the functional network with traffic information. Our analysis shows that the network is scale-free and has the small-world property. The evolution of triadic properties suggests that the network gears towards symmetric, t...

Cardiovascular diseases, metabolic disorders and obesity are a serious threat to civilization, especially in highly developed countries. Due the number of deaths complications they among health priorities Poland. The aim study is review literature on role functional food primary prevention cardiovascular diseases. Functional food, thanks its antioxidant, hypocholesterolemic anti-inflammatory pr...

The dimeric protein L7/L12 from bacterial ribosomes has a highly elongated and flexible structure. We have, using 1H NMR methods, analyzed the extent of the flexible region and also the size of the organized structures of the molecule. A number of mutants of the protein as well as monomeric and dimeric forms of the protein and a COOH-terminal fragment have been used for the identification of ce...

objective: oxidation of oils has an important effect on nutritional and organoleptic properties of foodstuffs. nowadays, new tendency has created a necessity to use natural compounds such as essential oils for producing functional foods. in this study, antioxidant, antifungal, and organoleptic properties of zataria multiflora boiss.(zmeo) and cinnamon zeylanicum essential oils (czeo) have been ...

Saffron is one of the highly exotic spices known for traditional values and antiquity. It is used for home décor besides serving as a colorant flavor and is widely known for medicinal value. Over the last few years, saffron has garnered a lot of interest due to its anti-cancer, anti-mutagenic, anti-oxidant and immunomodulatory properties. Integration of systems biology approaches with wide appl...

density functional theory (dft) based calculations have been performed to examine the relaxations of tautomers of 4–hydroxy–6–methylpyridin–2(1h)–one (mpo), as a representative of pyridinone derivatives, at the fullerene (c60) surfaces. optimized molecular properties including energies, dipole moments and atomic scale quadrupole coupling constants (cq) have been evaluated to investigate the str...

polypyrrole is one of the most useful conductive polymers, but green synthesis of this polymer has been restricted until now. the objective of the present paper is green synthesis of nano polypyrrole (ppy) by oxidative polymerization using urea-hydrogen peroxide. it was found that conductivity and morphology of polypyrrole are highly dependent on the reaction conditions such as the molar ratio ...

in the past decades, environmental pollution caused by plastic packing materials, restrictions of petroleum resources and their high price attracted many researchers to produce biodegradable packaging materials. poor mechanic properties and high water vapor permeability are two main defects of biodegradable polymers. nanotechnology is a modification method in this case. in the current study, th...

rhus coriaria l. is known as sumac. r. coriaria extracts are important in drug development with numerous pharmacological reputations in the south-eastern anatolia, mediterranean area and western asia especially in iran. regarding the new multi-functional properties of r. coriaria and the related valuable ongoing reports, we were prompted to review the phytochemical and pharmacological propertie...
