this paper presents the results of engineering geological studies of rock blocks along a road tunnel in nw iran. the tunnel is to cross the western alborz mountain range through 530 m in length with 11.2 m span and 8 m height. eocene tuffs and andesites crop out in whole of the tunnel route. numerical analyses are done using, a 3d stability analysis and visualization program, called unwedge tha...

This study was conducted to determine the chemical composition, metabolizable energy, digestibility and ability of gas production of Poa trivialis. Samples was collected at three phenological stages including: vegetative growth, flowering and seedling on two different elevations of 1300 to 1500 m and 2000 to 1800 m asl in Neor and Hir region as the first and second sites, respectively. Testing ...

PURPOSE To test the feasibility of pediatric perfusion imaging using a pulsed arterial spin labeling (ASL) technique at 1.5 T. MATERIALS AND METHODS ASL perfusion imaging was carried out on seven neurologically normal children and five healthy adults. The signal-to-noise ratio (SNR) of the perfusion images along with T1, M(0), arterial transit time, and the temporal fluctuation of the ASL ima...

Abstract Macrofungi is one of bio-medicinal sources containing various bioactive compounds, such as β-glucans, which are scientifically proven immunity booster against coronavirus, including Covid-19. Lawu Mountain Forest has been reported the macro fungi-rich ecosystems in Java. Due to its unique geography, each side mountain a different climate with southern slope typically more suitable for ...

BACKGROUND A two year seroepidemiological study was designed to find out the seroprevalence and risk factors of canine visceral leishmaniasis (CVL) among stray and owned dogs in Tehran and Alborz Provinces of Iran. METHODS Blood samples of 602 dogs living in 11 counties of Tehran and Alborz Provinces were taken by venipuncture in 2008-2010. After separation of blood sera, anti-leishmanial ant...

In this study, we collected 226 shrew specimens originating from 16 localities on the Guinean and Liberian sides of Mount Nimba. We surveyed all major vegetation zones 400 to 1600 m above sea level (asl), including forest savannah habitats. recorded 11 species, whose identifications were confirmed by genetic analyses classical morphometrics. Furthermore, provide cytogenetic data for five these ...
