rutting of hot mix asphalt pavements due to increased number of heavy vehicles, especially in tropical regions, causes several performance problems. large stone asphalt mixtures have more stiffness and shear resistance and so more rutting resistance compared to conventional mixtures. hence, using these mixtures in thick layers of hot mix asphalt pavements at tropical regions could be an appropr...

This paper considers the economic lot and delivery scheduling problem in a two-echelon supply chains, where a single supplier produces multiple components on a flexible flow line (FFL) and delivers them directly to an assembly facility (AF). The objective is to determine a cyclic schedule that minimizes the sum of transportation, setup and inventory holding costs per unit time without shortage....

both soil and water salinity is one of the main reasons in decreasing germination, seedling growth and establishment in many arid and semiarid parts of world especially in our country. for this reason in order to evaluate the effect of lentil seed size on germination and seedling growth properties that was under effect of salinity stress, a completely randomized design with factorial arrangemen...

giant cell fibroma (gcf) was described as a new entity of fibrous hyperplastic soft tissue. it seems that stimulus from an unexplained origin can have a role in its etiology. histopathologically gcf is consisted of multinucleated fibroblasts that have oval shape nuclei within the eosinophilic cytoplasm. surgical excision is the treatment of choice and recurrence is very rare. here we report a c...
