this study investigated the concentration/time dependent effects of nanosilver colloid on the motionparameters of the ejaculated ram spermatozoa in vitro. after incubation of sperm samples for 30, 60, 120 and 180 min in the presence of nanosilver colloid (0, 0.001, 0.01, 0.1, 1 and 10 ppm), the motion parameters were evaluated by computer assisted sperm analysis. there was a significant (p
The possibility of using a steel plant by-product (converter sludge) as an iron fertilizer was investigated. This compound consists of 64% Fe oxides. Considerable amounts of elements such as Ca, Si, Mn, P, and K are also present in the sludge. To study the converter sludge, an incubation experiment was carried out on three calcareous soils. Treatments were 0, 4, and 8 percent of converter sludg...
The research aimed to analyzing the proportion of daily abundance phytoplankton based on change in time best incubation period. implementation from November 2018 January 2019 marine waters Barrang Lompo Island. Water samples identify were taken by filtering 100 liters seawater using a plankton net. sampling was carried out at observation 10:00; 11.00; 12.00; 13.00; 14.00 period (10.00-14.00). B...
