Growth Properties Of Chub (Leuciscus Cephalus L., 1758) In Lake Tödürge (Zara/Sivas), Bülent Ünver, Jüli̇de Tanyolaç
Turkish Journal of Zoology
In this research, sex and age compositions, age-length, age-weight, length-weight relations, condition factors were investigated on 674 chub (Leuciscus cephalus L., 1758) specimens caught from Lake Tödürge, Sivas between April and November 1994. The age composition of L. cephalus specimens were between I-VII years and sex percentages were calculated as 68.25 % for females and 31.75 % for males. Determined minimum and maximum forklength values were 53 and 299 mm; weights were 1.5 and 347.1 g. Von Bertalanffy equations of L. cephalus specimens as length-growth and weight-growth were established as L_t = 474.19 [1-e^{-0.10608(t+0.3805)}] for females; L_t = 545.26 [1-e …

Some Results On Space-Like Line Congruences And Their Space-Like Parameter Ruled Surface, E. Özyilmaz
Some Results On Space-Like Line Congruences And Their Space-Like Parameter Ruled Surface, E. Özyilmaz
Turkish Journal of Mathematics
Using dual vectors, space-like ruled surfaces was introduced in [2]. In this paper, we define space-like line congruence and their space-like parameter ruled surfaces {\mathbf R_{11}(t)} and {\mathbf R_{21}(t)} of R_1^3. Then, by choosing space-like parameter ruled surfaces as space-like principle ruled surfaces, we obtain some relations among the magnitudes of space-like ruled surfaces {\mathbf R_1(t)}, {\mathbf R_{11}(t)}.

The aim of this study is to select desirable poppy lines introduced from different regions in terms of plant and agricultural characteristics. In the study, morphological and phenological observations on plants were done and seed, capsule yields, morphine ratio and morphine yield of each line were determined along two years. Only second year's results were evaluated for planting time as winter and spring. According to the results obtained, in the first year, flowering period varied between 79 and 116 days. While seed yield, capsule yield, morphine ratio and morphine yield varied between 8.22-76.75 kg/da, 6.14-69.72 kg/da, 0.57-1.40 %, 0.046-0.458 kg/da, …

Compatiple And Noncompatiple Stem Taper Equations For Alder, Hakki Yavuz, Nedi̇m Saraçoğlu
Compatiple And Noncompatiple Stem Taper Equations For Alder, Hakki Yavuz, Nedi̇m Saraçoğlu
Turkish Journal of Agriculture and Forestry
In this study, compatible and noncompatible stem taper equations were developed for alder (Alnus glutinosa (L.) Gaertn.) depending on 510 sample trees data taken from alder stands in Black Sea Region. For estimating only stem tapers of sample trees, the noncompatible stem taper equation developed by Kozak (10) was the best according to average residual (bias), standart deviation of residuals (precision) and percent variation explained criteria, among all compatible and noncompatible stem taper equations tested in this study. Besides, according to the same criteria, for estimating stem tapers, total tree volume and volume ratios together, the compatible stem taper equation …

Turkish Journal of Medical Sciences
The effects of Rumex patientia and Urtica dioica on levels of blood glucose, plasma amino acids and other parameters, urine excreta, and liver and kidney histology were examined in diabetic rats induced by streptozotocin. Streptozotocin increased blood glucose and changed the levels of amino acids and other parameters, and caused degenerative changes in the liver and kidney. Rumex patientia had some protective effect on these parameters changed by streptozotocin, while Urtica diocia had no protective effects.

Fire Reterdant Chemicals Affecting Combustion Resistance Of Wood, Yalçin Örs, Abdullah Sönmez, Burhanetti̇n Uysal
Turkish Journal of Agriculture and Forestry
Wood is an important material used in construction elements. However since it can be affected by biotic and abiotic deteriorating agents, it should be treated with chemical impregnating materials prior to use. In this study, the effects of water-soluble impregnating chemicals on the combustion resistance of wood was investigated. For this purpose, panels were prepared with oriental beech wood (Fagus orientalis L.) and pine wood (Pinus silvestris L.), which are widely used in industry. These panels were impregnated with potassium nitrate (KNO_3), zinc sulfate (Zn SO_4), sodium tetra borate (Na_2 B_4 O_7), sodium sulfate (Na_2 SO_4) and copper sulfate (Cu_2SO_4). …
Water Consumption And Growth Of Some Barley Genotypes Under Eskişehir Conditions, Mehmet Aydin, A. Vahap Katkat
Water Consumption And Growth Of Some Barley Genotypes Under Eskişehir Conditions, Mehmet Aydin, A. Vahap Katkat
Turkish Journal of Agriculture and Forestry
Using eight barley cultivars field experiments were carried out in Eskişehir, from 1991 through 1994. Water consumption and dry mater yield of genotypes were studied. Also, the yields and yield components as well as their relationship with dry matter production in different growing periods were studied. There was no significant difference among evapotranspiration of genotypes. The Water Use Efficiency (WUE) varied with year. Mean annual WUE of genotypes varied from 3.6 to 4.75 kg / da^-1 mm^-1 for biological yield, and from 1.08 to 1.45 kg / da^-1 mm^-1 for grain yield. Total dry-matter production throughout the growing season and …
