Nondestructive Determination Of Spruce Lumber Wood Density Using Drilling Resistance (Resistograph) Method, Bi̇lgi̇n İçel, Gürcan Güler
Nondestructive Determination Of Spruce Lumber Wood Density Using Drilling Resistance (Resistograph) Method, Bi̇lgi̇n İçel, Gürcan Güler
Turkish Journal of Agriculture and Forestry
The use of Resistograph for the purpose of nondestructive evaluation of certain properties of standing trees and wooden materials has increased in recent years. The resistance to penetration of a fine drill bit is measured and recorded by the device. A number of properties of the wood can be assessed by the amplitude values obtained from the Resistograph. The aim of this study was to assess the utility of the IML-Resistograph F 500 as a nondestructive tool for estimating spruce wood density using the amplitude data generated and the application of statistical modeling. Wood density data were determined using a …

The effects of fermentation with 2 different starter culture mixtures composed of lactic acid bacteria (LAB) on some physicochemical, microbiological, sensorial, and rheological characteristics of boza, a traditional fermented Turkish beverage, during storage for 10 days at 8 ^°C were investigated. Lb. casei Shirota adapted in boza well and provided the boza with a probiotic property. At the beginning of storage, the Lb. casei Shirota count of boza was 6.83 log cfu mL^{-1}, while total LAB counts were 8.01 and 8.11 log cfu mL-1 for S1 and S2 samples, respectively. A decrease in pH values was observed when the counts …

The problem of water movement through the root zone has attracted increasing interest during the last few decades. In this research, the spatial and temporal pattern of root water uptake in wetted soil was studied in the root zone of a 6-year-old apple tree. An important part of the root water uptake model is root length density, which was measured by sampling soil cores in one quarter of the root zone. The exponential model better described the observed apple root distribution. The measured data were compared against the outputs of the root density distribution model. A normalized root length density …
Comparison Of Erosion And Runoff Predicted By Wepp And Agnps Models Using A Geographic Information System, Hali̇l Kirnak
Comparison Of Erosion And Runoff Predicted By Wepp And Agnps Models Using A Geographic Information System, Hali̇l Kirnak
Turkish Journal of Agriculture and Forestry
The Water Erosion Prediction Project (WEPP) model and the Agricultural Non-Point-Source Pollution Model (AGNPS) were used in conjunction with a geographic information system (GIS) database to predict runoff and sediment discharges for Rock Creek watershed, an agricultural watershed in Ohio, USA. Observed and predicted values were compared for selected storm events in 1988 and 1990. The statistical evaluation of the WEPP and AGNPS models showed that WEPP predicted average runoff, peak runoff and sediment yield better than AGNPS. WEPP and AGNPS overpredicted peak runoff rates compared to observed data by 15.5% and 26.5%, respectively. The t-test showed that there was …
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
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 …
