Combinatorial Optimization In Forest Ecosystem Management Modeling, Emi̇n Zeki̇ Başkent
Combinatorial Optimization In Forest Ecosystem Management Modeling, Emi̇n Zeki̇ Başkent
Turkish Journal of Agriculture and Forestry
Modeling forest management activities has been tackled by scientists over the last two decades. Both simulation and optimization techniques have been used in solving forest management planning problems. With the introduction of ecosystems management that focuses on the sustainable production and maintenance of ecological, social and economical values, neither approach provided a credible solution technique to help design the complex structure of forest management activities. Alternative to these, is a group of meta-heuristic or combinatorial optimization techniques which have just gained the attention of forest modelers. In this paper, an attempt is made to introduce the concept of combinatorial optimization, …

Water Diffusion Coefficients Of Selected Legumes Grown In Turkey As Affected By Temperature And Variety, Ferda Seyhan Gürtaş, M. Mehmet Ak, E. Özgül Evranuz
Turkish Journal of Agriculture and Forestry
The kinetics of water absorption by chickpeas (Koçbaşı, Kuşbaşı), lentils (green Pul) and beans (Battal, Dermason, Horoz, Şeker) grown in Turkey were studied by a gravimetric method during soaking at 15, 25 and 40ºC to determine moisture diffusivity of these selected legumes. The water diffusion coefficients of the legumes were in the range 9.71x10^{-11} - 5.98x10^{-10} m^2/s for the chickpeas, 3.53x10^{-10} - 1.33x10^{-9} m^2/s for the lentils and 4.35x10^{-11} - 3.79x10^{-9} m^2/s for the beans. An Arrhenius-type equation described the strong temperature effect on the diffusion coefficient with activation energies of 48.6-49.8 kJ/g-mol for chickpeas, 39.7 kJ/g-mol for lentils, and …
