excessive production and stockpile of scrap tires cause some environmental and sanitary risks throughout the world. to manage these materials, possible use of soil-tire mixtures has been recently propounded in civil engineering projects. a few studies previously have been conducted to evaluate behavior of clay-tire mixtures, while swelling properties, consolidation and settlement characteristic...

The goal of this study was improvement of sandy soil using a combination of polystyrene foam container waste and Portland cement. For this purpose, Babolsar sand was used as the base soil. Strips of disposable polystyrene foam container waste in “chips” of 50 ´ 5 mm and 50 ´ 10 mm were added to the soil at 0.0%, 0.1%, 0.2% and 0.3% by weight along with 3% Portland cement at a relative density o...

In this study, changes in some quality parameters of fish chips produced from sand smelt (Atherina boyeri, RISSO 1810) during storage period (at -18  o C for 6 months) were determined.  The difference between the amount of moisture, crude protein, crude fat and crude ash components of raw fish in fish chips was significant (P<0.05). Pre-frying  process resulted in a decrease in all fatty acid c...

a functional treatment for skeletal damages in orthopedic and oral maxillofacial surgeries is required. platelet growth factors such as platelet derived growth factor (pdgf), bone morphogenic factor (bmp), transferring growth factor-β (tgf-β) and insulin-like growth factor-1 (igf-1) proceed wound healing and bone regeneration. in the present study we focused on the effect of platelet rich plasm...

pepino (solanum muricatum), a new vegetable crops, is from solanaceae family and cultivated as annual crops. in order to investigate the effects of mulch on weed dry weight in pepino and soil humidity and temperature, an experiment was conducted based on randomized completely design with three replication at the ferdowsi university of mashhad green house, during 2009. treatments included rice s...

background &amp; aim: chemicals antioxidants and lipid oxidation products are known as cancer-causing factors in food systems. in this study, the effect of essential oil from heracleum lasiopetalum fruits on lipid oxidation and physicochemical properties of potato chips in comparison with commercial antioxidant has been investigated.experimental: the essential oil of h. lasiopetalum extracted u...
