background: previous anatomic and radiological studies have described the relationship of the clavicle to major neurovascular structures in healthy subjects. we were curious about this relationship in patients with a clavicle fracture and if it is different from non-fractured clavicles.   methods: we retrospectively identified all patients with a clavicle fracture between july 2001 and october ...

Avila and Molina [1] introduced the notion of generalized weak structures which naturally generalize minimal structures, generalized topologies and weak structures and the structures α(g),π(g),σ(g) and β(g). This work is a further investigation of generalized weak structures due to Avila and Molina. Further we introduce the structures ro(g) and rc(g) and study the properties of the structures r...

the benefits of textual input enhancement in the acquisition of linguistic forms have produced mixed results in sla literature. the present study investigates the effects of textual enhancement on adult foreign language intake of two english linguistic forms-subjunctive mood and inversion structures-to explore the role of the type of linguistic items in input enhancement studies. it also invest...

We characterize the natural diagonal almost product (locally product) structures on the tangent bundle of a Riemannian manifold. We obtain the conditions under which the tangent bundle endowed with the determined structure and with a metric of natural diagonal lift type is a Riemannian almost product (locally product) manifold, or an (almost) para-Hermitian manifold. We find the natural diagona...

We examined the cytotoxic effects of dillapiole, a phenylpropanoid with antileishmanial, anti-inflammatory, antifungal, and acaricidal activities, on the blastocyst stage of mouse embryos, subsequent embryonic attachment and outgrowth in vitro, and in vivo implantation via embryo transfer. Blastocysts treated with 2.5-10 μM dillapiole exhibited a significant increase in apoptosis and correspond...

avila and molina [1] introduced the notion of generalized weak structures which naturally generalize minimal structures, generalized topologies and weak structures and the structures α(g),π(g),σ(g) and β (g). this work is a further investigation of generalized weak structures due to avila and molina. further we introduce the structures ro(g) and rc(g) and study the properties of the structur...

doing a piece of research on acquisition of second language phonetics theoretically will justify the exact stages of language trans- fer and further predicts the existence of systematicity and difficulty order (eckman, 2008). the present research is an attempt to provide new evidence for the efficacy of second language acquisition to devel- opmental stages of acquisition of phonological structu...

volumetric techniques were employed to study the adsorption of co2 on a purified multi-wall carbon nanotubes (mwnt’s) sample, as a mesoporous material, at isothermal conditions of 288, 293 and 298 k and pressures ranging from 30 to 150 kpa. langmuir, freundlich and sips equations were used to represent the isotherms. also the parameters of these fitted isotherm models have been determined. the ...

administrative regulations for water flow decrease distribution efficiency and effect the economical operation of irrigation networks. complications in distribution systems and the decrease in availability of water require study of the hydraulic performance of existing flow control structures. control systems designed by neyrpic (zayandeh rud network) and usbr (doroodzan network) were investiga...
