Beef and milk price links in Turkey
(2013) Saghaian Sayed; Özertan Gökhan; Tekgüç Hasan
This article addresses the recent beef price spikes in Turkey, using contemporary time-series analysis. The arguments point to the impact of low milk prices that led to liquidation of dairy herds and decline of beef prices initially due to the liquidation and increased meat supply, and subsequent price increases in the next year due to decreased supply. The results revealed that dairy herd liquidation had a delayed impact of a year to 18 months on farm, wholesale, and retail beef prices, Those effects wore off over a two-year time period.
New Exponential and Complex Traveling Wave Solutions to the Konopelchenko-Dubrovsky Model
(HINDAWI LTD, 2019) Dusunceli, Faruk
The Konopelchenko-Dubrovsky (KD) system is presented by the application of the improved Bernoulli subequation function method (IBSEFM). First, The KD system being Nonlinear partial differential equations system is transformed into nonlinear ordinary differential equation by using a wave transformation. Last, the resulting equation is successfully explored for new explicit exact solutions including singular soliton, kink, and periodic wave solutions. All the obtained solutions in this study satisfy the Konopelchenko-Dubrovsky model. Under suitable choice of the parameter values, interesting two- and three-dimensional graphs of all the obtained solutions are plotted.
