Heavy Metal Effects On P, Ca, Mg, And Total Protein Contents In Embryonic Pleopodal Eggs And Stage-1 Juveniles Of Freshwater Crayfish Astacus Leptodactylus (Eschscholtz, 1823), Utku Güner
Turkish Journal of Biology
To determine the potential biochemical effects of heavy metal pollution on aquatic organisms, pleopodal eggs, and stage-1 juveniles of the freshwater crayfish, Astacus leptodactylus (Eschscholtz, 1823), was exposed to a non-essential (Cd) and an essential (Cu) metal, either singly or in combination. Three different sublethal doses (0.1, 0.5, and 1 ppm) and 1 interaction dose (0.1 ppm Cu + 0.1 ppm Cd) were used to evaluate the accumulation and toxicity. The effects of 2 doses of metals on P, Ca, total protein, and Mg contents in the embryonic pleopodal eggs and in stage-1 juveniles were examined by an autoanalyzer. The …
Changes In Hay Yield And Quality Of Bulbous Barley At Different Phenological Stages, Ferat Uzun
Changes In Hay Yield And Quality Of Bulbous Barley At Different Phenological Stages, Ferat Uzun
Turkish Journal of Agriculture and Forestry
The objective of this study was to determine the changes in hay yield and quality components at different phenological stages of a bulbous barley (Hordeum bulbosum L.) population handpicked from natural flora during 2003-2007 in Samsun, Turkey. The phenological stages of bulbous barley during spring-summer (grazing maturity, early heading, heading, and milk-dough) and autumn (early growing) were investigated. Significant differences were observed in hay yield, relative feed value (RFV), crude protein (CP), acid and neutral detergent fiber (ADF and NDF), Ca, Mg, K, P, Mn, Fe, and Zn concentrations, and K(Ca + Mg)^{-1} and Ca P^{-1} ratios of DM, depending …

Isolation And Identification Of Culturable Forms Of Bacteria From The Sweet Potato Whitefly Bemesia Tabaci Genn. (Homoptera: Aleyrodidae) In Jordan, Mazen Ahmad Ateyyat, Mohamad Shatnawi, Mohammad Al-Mazra'awi
Turkish Journal of Agriculture and Forestry
Homopteran insects contain bacteria in their cells and tissues known as "secondary symbionts," which under special environmental circumstances act against their host insects. In this study, both molecular- and culture-based methods were used to characterize the bacteria associated with the whitefly in Jordan. We isolated, cultured, and identified 11 species of bacteria from nymphs (6 species), adults (8 species), and parasitized pupae (2 species) of the whitefly Bemesia tabaci collected from different vegetable crops planted in different localities in Jordan. The identities of the cultured bacteria were evaluated using PCR with sequencing of 16S rRNA gene fragments and fluorescence in …

Turkish Journal of Agriculture and Forestry
The aim of this study was to determine the effectiveness of fennel (Foeniculum vulgare Mill.) leaves as food on development, survival, and reproduction in Podisus nigrispinus (Dallas). Newly hatched P. nigrispinus nymphs were used in this study. The prey consisted of 3rd-instar Alabama argillacea (Huebner) larvae. Fennel and cotton leaves were not sufficient to enable the full development of the predator to its adult stage. It was verified that 35% of the nymphs that fed on cotton leaves and water, and 31% of the nymphs that fed on fennel leaves and water completed their 2nd instar in 5.68 days and …

Turkish Journal of Agriculture and Forestry
The responses of sludge faecal coliforms, Salmonella, and Ascaris lumbricoides to heat drying, solar dehydration, and inactivation in soil are examined in this study. The presence of Salmonella in raw sludge cake after treatment was low, and absent for most of the cases. Likewise, the viable Ascaris eggs were not determined because of absent or low prevalence. Faecal coliforms, on the other hand, drastically decreased from 4.2 × 10^7 MPN g^{-1} Dry Solid (DS) to absence by heat drying. Faecal coliform numbers in solar and non-solar drying treatments were not declined below 1.0 × 10^3 MPN g^{-1} after drying to …
Effect Of Transformer On Stochastic Estimation Of Voltage Sag Due To Faults In The Power System: A Pscad/Emtdc Simulation, Nita R. Patne, K. L. Thakre
Effect Of Transformer On Stochastic Estimation Of Voltage Sag Due To Faults In The Power System: A Pscad/Emtdc Simulation, Nita R. Patne, K. L. Thakre
Turkish Journal of Electrical Engineering and Computer Sciences
Voltage sags in the electric power system are mostly due to faults in the power system. Voltage sag is characterized by its magnitude (the retained voltage), phase-angle jump, unbalance in the sag in the three phases, and duration. Type of transformers in the electrical system is the important parameter influencing the characteristic of sag at the node where sensitive loads are connected. For sensitive loads it is necessary to estimate how many times in a year the voltage at their terminal will experience sag to avoid tripping of operation. In this paper the effect of transformer on stochastic estimation of …

Active Illumination And Appearance Model For Face Alignment, Muhi̇tti̇n Gökmen, Fati̇h Kahraman, Sune Darkner, Rasmus Larsen
Turkish Journal of Electrical Engineering and Computer Sciences
Illumination conditions have an explicit effect on the performance of face recognition systems. In particular, varying the illumination upon the face imposes such complex effects that the identification often fails to provide a stable performance level. In this paper, we propose an approach integrating face identity and illumination models in order to reach acceptable and stable face recognition rates. For this purpose, Active Appearance Model (AAM) and illumination model of faces are combined in order to obtain an illumination invariant face localization. The proposed method is an integrated Active Illumination and Appearance Model (AIA) which combines identity, illumination and shape …

Turkish Journal of Electrical Engineering and Computer Sciences
In this study, we apply State Dependent Riccati Equation (SDRE) based optimal control technique to a nonlinear tumor growth model. The model consists of three biological cells which are normal tissue, tumor and immune cells. The effect of chemotherapy treatment is also included in the model. Chemotherapy administration is considered as a control input to the nonlinear cancer dynamics and the amount of administered drug is determined by using SDRE optimal control. The optimal control is applied to the model in order not only to drive the tumor cells to the healthy equilibrium state but also to minimize the amount …

Morphine Modulates Microvascular Leakage Dose-Dependently In The Airway Of Ovalbumin-Sensitized Rats, Seyfullah Oktay Arslan
Turkish Journal of Medical Sciences
To investigate the effect of morphine on ovalbumin-evoked airway microvascular leakage in sensitized rats. Materials and methods: Rats were sensitized on days 0, 14, and 21 with ovalbumin. Intravenous ovalbumin (2 mg/kg) or capsaicin (50 µg/kg) increased the extravasation of Evans blue dye in trachea, bronchi, and intra-pulmonary tissues of sensitized rats. Results: Morphine (1-10 mg/kg) inhibited ovalbumin-evoked increase in microvascular plasma leakage in a dose-dependent manner; however, it had no significant effect at the doses of 0.1 or 30 mg/kg. In addition, morphine, at the doses of 1-30 mg/kg, abolished microvascular leakage increased by capsaicin. The inhibition caused by …
