effects of different amounts of morning liming on blood ionic parameters and blood biochemical parameters of cultured carp ponds in dikjeh area of gonbad were investigated. 9 ponds (3 hectars) were chosen and divided in 3 treatments (1- liming 750 mg/l, 2- liming 1250 mg/l, 3- liming 1750 mg/l). liming had significant effect on blood hematocrite (p0.05) were observed between other blood paramet...

thermoluminescence (tl) dating was established in oxford to fulfil the demand for dating ceramics and other heated man made products (aitken, 1985).  it determines the time elapsed since the mineral grains have been heated. following the establishment of tl dating method, it was used to date fired materials such as pottery, flint and etc. optically stimulated luminescence (osl) determines the t...
