The Effect Of Atp-Dependent Potassium Channel Blocker, Glimeprid, On The Arrhythmiasobserved Following Ischemia And Reperfusion In Anesthesized Rats, Ömer Bozdoğan, Istvan Lepran, Julius Gy Pap
Turkish Journal of Veterinary & Animal Sciences
In recent years, it has been discussed intensively whether the potassium channel openers or blockers have antiarrhythmic effect during ischemia and reperfusion. Although there are many in vitro studies suggesting the potassium channel blokers especial-ly glibenclamide have antiarrhythmic effect, there is a very few in vivo expertiment to support the same result. In the present study, left arteria coronaria descendence (LAD) was ligated in 6min and following reperfusion was made by relasing the ligature. ECG and arterial blood pressure were recorded during the ischemia and reperfusion. The heart rate, the length of arrhythmia, the score of arrhythmia and the number …

Signal Injection With Perceptual Criteria, T. Engi̇n Tuncer
Signal Injection With Perceptual Criteria, T. Engi̇n Tuncer
Turkish Journal of Electrical Engineering and Computer Sciences
In this paper, a novel method for increasing the coding performance and information transmission capacity is presented. This method is mainly based on perceptual modelling of input signal such as speech or audio. Presented approach may be seen as an alternative to transforms which dynamically change analysis window for better energy compaction. A perceptual model is established in order to obtain a global masking threshold in frequency below which sounds become inaudible. Certain criteria are developed for identifying the signal injection bands. A new multiband filter design method which is a generalization of windowing method is used to separate the …

State Of Art In Realistic Head Modeling For Electro-Magnetic Source Imaging Of The Human Brain, Nevzat G. Gençer, İ. Oğuz Tanzer, M. Kemal Özdemi̇r, Can E. Acar, Mert Sungur
Turkish Journal of Electrical Engineering and Computer Sciences
Electric currents produced by the neural activity in the brain create electric potentials on the scalp and magnetic field distribution outside the scalp. Measuring electric and magnetic fields provides a means to understand the spatio-temporal distribution of the neural activity. The representations of the intracellular electric current of active cell populations based on bimodal data are called electro-magnetic source image (EMSI). With the recent development of large arrays of magnetic sensors, and systems for measuring scalp voltages at more than 100 locations, it is now feasible to implement computational methods that employ numerical models which incorporate the correct geometry and …

Effects Of Short Trem High Carbon Dioxide Treatment On Tomato Ripening, Ali Batu, A. K. Thompson
Effects Of Short Trem High Carbon Dioxide Treatment On Tomato Ripening, Ali Batu, A. K. Thompson
Turkish Journal of Agriculture and Forestry
Tomato ( Lycopersicon esculentum Mill.) fruits (Cv Criterium) were harvested at the mature green stage and stored at 13°C in controlled atmosphere (CA) conditions for 1, 3 and 5 days. The CA conditions were 5, 10, 20, 40 and 60% CO 2 all with 5.5%O 2 plus air as control. The tomatoes were then stored at 20°C in air until they were fully ripe. At that time colour, firmness, titratable acidity, total soluble solids (TSS) and days to ripening were measured. Fruit exposed to CO 2 for 5 days subsequently ripened more slowly than those exposed only one day. The …

Forecasting Of The Long-Term Allowable Cut For The Akçasu Forestry Enterprise, Altay Uğur Gül
Turkish Journal of Agriculture and Forestry
The long-term allowable cut was ensured using data of Forest Menegement Plan of the Akçasu Forest enterprise. In addition, actuel forest state was approximated to an optimal forest state within different rotation age. Three forest management units were established. A linear programming model was developed on used to test three different strategies for the black pine and beech management unit and five different strategies for the oak management unit. For the first period, the regeneration, afforestation area, allowable cut and total cut was 210.0 and 341.0 hectar, 58546.0 m 3 and 1764516 m 3 , respectively.
Genetic Relationships Of Turkish Bread Wheat Cultivars, Nusret Zenci̇rci̇
Genetic Relationships Of Turkish Bread Wheat Cultivars, Nusret Zenci̇rci̇
Turkish Journal of Agriculture and Forestry
Forty-two bread wheat cultivars released up to 1990 in Turkey have been investigated in order to understand their genetic relationships. Correlation, regression and principal component analyses have been applied to cultivar-to-cultivar parentage coefficients and similarity indices based on pedigree data. Correlation and regression analyses between cultivar-to-cultivar parentage coefficients and similarity indices have shown higher relationships implying that both estimates could be used interchangeably to predict genetic relationships in cultivars. Principal component analyses failed to group cultivars clearly, but some subgrouping were obtained.

Effects Of Modified Atmosphere Packaging On Post Harvest Qualities Of Pink Tomatoes, Ali Batu, A. Keith Thompson
Turkish Journal of Agriculture and Forestry
An experiment retail plastic packaging system was used to compare the atmospheric composition within sealed packs containing tomato fruits. A range of plastic films with different permeability properties were tested to study the effects of these conditions on the changes in postharvest qualities of tomatoes harvested at the pink stage of maturity and stored at 13 o C for 60 days. The films used were 20 micron (PE20) and 50 micron (PE50) polyethylene, 10 micron polyvinylcholoride (PVC) or 25 micron polypropylene (PP) compared with unwrapped fruit as a control. Tomatoes were evaluated for changes in colour, firmness, weight, titratable acidity, …
Some Factors Affecting On Determination And Measurement Oftomato Firmness, Ali Batu
Some Factors Affecting On Determination And Measurement Oftomato Firmness, Ali Batu
Turkish Journal of Agriculture and Forestry
Firmness is one of the most important factor for determination of tomatoes quality. Distructive measurement of tomato firmness is one of the evaluation methods of fruit firmness. The Universal Instron is most common used machine for measurement of most adeqequate fruit firmness. During destructive measurement of firmness considedation of force or deformation values as a firmness of fruits could give incorrect result and taking epicarp strength over deformation values is more accurate to concern the firmness of tomato. Two of possible minimum firmness limits were suggested for tomato fruits at the point of retail marketing or using at home. All …
