Articles in general and definite articles in particular can create problems even long after all other aspects of English have been mastered. The present article investigated the learnability problems related to the acquisition of count-mass distinction of English nominals by Persian L2 learners. The theoretical underpinning of the study is the interpretability hypothesis (Tsimpli & Dimitrakopou...

The possibility of employing internal wall as mass absorber in rectangular water storage tanks subjected to harmonic ground motion excitation is investigated in this paper. Internal walls are used in these tanks usually for service performance purposes, which could be used as mass absorber to control seismic demand on tank's exterior walls. Derivation of the response of the coupled system inclu...

A series of column and flow-cell experiments was conducted to investigate the impact of non-uniform organic-liquid distribution on the relationship between reductions in contaminant mass discharge and reductions in source zone mass under conditions of enhanced-solubilization flushing. Trichloroethene was used as the model organic liquid, and SDS (sodium dodecyl sulfate) and ethanol were used as...

a five-year-old holstein cow with a history of vaginal prolapse was admitted to the large animal clinic, faculty of veterinary medicine, university of tabriz. according to the owner, she had a 5-month history of vaginal prolapse and frequent sanguineous discharge from the vagina. appetite was normal and its last parturition was two months ago. clinical examination revealed a tumor like mass tha...

In recent years, impinging streams have received increasing interest for their high efficiency in heat and mass transfer. This numerical study was conducted to investigate flow and heat transfer characteristics of one-way opposing jets of non-Newtonian fluids. Effects of Reynolds number impinging angle, momentum ratio and flow behavior index on mixing index were evaluated. The results showed im...
