The present study was the first attempt to survey the diversity of fish zoonotic parasites in the southern region of Saudi Arabia, particularly the Najran area, from October 2012 to October 2013. Approximately 163 fish representing seven species (two of freshwater fish and five of marine fish) were examined for fish-borne trematode metacercariae using the compression technique, and for zoonotic...

Male movements serve as courtship signals in many animal species, and may honestly reflect the genotypic and/or phenotypic quality of the individual. Attractive human dance moves, particularly those of males, have been reported to show associations with measures of physical strength, prenatal androgenization and symmetry. Here we use advanced three-dimensional motion-capture technology to ident...

sharp increase in oil price and the volatility in recent decades have attracted most researchers towards the field of energy. it seems not only the direct oil price, but also the uncertainty caused by the oil price volatility affect the raw oil supply. in this research the effect of oil price volatility on oil supply has been estimated using monthly time series data from january 1980 to septemb...

In work from 2004, Cimasoni gave a geometric computation of the multivariable Conway potential function in terms generalization Seifert surface for link called C-complex [2]. These surfaces were introduced by Cooper [9], [10] 2-component links and used to compute Alexander invariants, signatures nullities. presents sequence moves which relate any two C-complexes link. gives an extension Cooper'...

Communicative moves and lexical cohesion patterns (LCPs), as mounting evidence shows, are two important indicators in writing and publishing the RAs. However, the interaction between these two crucial elements and the contribution of this interaction to the failure or success of the RAs have not been given due attention to date. Having this in mind and based on a sound theoretical framework, at...
