conclusions the hav seroprevalence of 90.8% in the studied region may be representative of a highly endemic region of hav that does not require a vaccination program to be commissioned. results it was found that 455 out of 501 (90.8%) serum samples, including those of 211 (42.1%) men and 290 (57.9%) women, were positive for hav igg antibody. education level, age, marital status, and ethnicity w...

The genus Satureja L. (Lamiaceae) consists of more than 200 species of herbaceous perennials worldwide. The Mediterranean region can be described as the center of the genus (1). This genius in flora of Iran is represented by fourteen species distributed commonly in rocky mountains (2, 3). Nine Satureja species has been reported in ìFlora Iranicaî (4), two of which, S. kallarica Jamzad and S. ba...

First-principles calculations based on density functional theory and the pseudopotential method have been used to investigate the energetics of H2O adsorption on the (110) surface of TiO2 and SnO2. Full relaxation of all atomic positions is performed on slab systems with periodic boundary conditions, and the cases of full and half coverage are studied. Both molecular and dissociative (H2O → OH ...

In this contribution we present ab initio density-functional-theory (DFT) calculations for CeO2 monolayers on the Pt(111) surface. The ceria surface and ceria-metal interface are of great interest because of the oxygen-storage and release capabilities of ceria, which are widely utilized in catalysis. Both the experimentally reported 3 : 4 [(4 × 4)] and 5 : 7 [(1.4 × 1.4)] matching geometries of...

First-principles molecular dynamics simulations having a duration of 8 ps have been used to study the static, dynamic and electronic properties of l-Ga at the temperatures 702K and 982K. The simulations use the densityfunctional pseudopotential method and the system is maintained on the BornOppenheimer surface by conjugate gradients relaxation. The static structure factor and radial distributio...

This study identifies and examines drivers barriers toward effective integrated sustainable management governance practices based on ecosystem services’ perspective of the Kurdistan Region Iraq’s water area. A combination a systematic literature review 28 individuals from Ankawa, Kasnazan, Haran City, Eskan, Bakhtiari, Tairawa, Mastufi, Khabat Saiudawa were randomly interviewed. The decisions t...

Pleurotus eryngii is a mushroom growing in the Bakhtiari province of Iran and is known as a mountain fungus. The fresh fungus is used as a food, and when dried its powder has been used as an anthelmintic drug. We decided to study the anthelmintic activity of P. eryngii on Hymenolepis nana (cestode) and Syphacia obvelata (nematode), using experimental animals. Water extract of P. eryngii wa...
