Time series modelling for goat and cow milk price index forecasting by trend analysis and Holt’s method

ERYÜRÜK, Şule | ÇİĞDEM, Hanne

Goat and cow milk is a fundamental agricultural product. Multiple factors can affect the price of milk over time such as production conditions, consumption demand, financial crisis and inflation. Dynamics of the milk price data should be considered to determine trend, cycle, or seasonality in the milk market so each pattern may affect the forecasting method should be used and the estimation results. Hence, the aim of this study is finding the pattern of the milk price time series data and estimation for the next 3 monthly periods. Historical data of Goat Milk and Cow Milk was used from the Agr ...Daha fazlası

ERYÜRÜK, Şule | ERYÜRÜK, Kağan

In columns packed with glass beads in the range of 0.25 mm to 3 mm in diameter, the effect of the number of cells deposited in hydraulic conductivity of porous media using CaCO3 precipitation produced by Sporosarcina pasteurii (ATCC 11859) was investigated in the present study. Following the introduction of resting Sporosarcina pasteurii cells into the columns, a precipitation solution containing 500 mM CaCl2 and 500 mM urea was injected into the columns under continuous flow conditions. To investigate the relation between deposited cell number and hydraulic conductivity, Response surface meth ...Daha fazlası
