Comparative Histological Structure Of The Sinus Node In Mammals, Abolghasem Nabipour
Turkish Journal of Veterinary & Animal Sciences
The main function of the sinus node is to provide the electrical impulse responsible for normal cardiac rhythm. The rhythmic coordination depends on the passage of the excitation wave by the heart through its conductive system of impulse. There is considerable variability in the size and exact location of the sinus node of individual hearts even within the same species. Histological features of the sinus node including the cells, the nodal artery, the collagen framework, and the innervation, and also some physiological characteristics of the node, will be discussed.

Effects Of Zinc On Growth Performance And Biochemical Parameters Of Piglets, Kun-Kun Wang, Hua-Wei Cui, Jian-Yi Sun, Li-Chun Qian, Xiaoyan Weng
Turkish Journal of Veterinary & Animal Sciences
The effects of zinc on growth performance, activities of enzymes, and concentrations of hormones were investigated in this study. Crossbred (Duroc × Landrace × Large White) piglets (initial body weight: 26.66 ± 2.45 kg) were randomly assigned into 4 groups receiving a basal diet and were supplemented with 60, 300, 1000, or 3000 mg/kg of zinc (as ZnSO_4^.7H_2O). The results showed that supplementation of zinc at 3000 mg/kg increased (P < 0.05) the average daily feed intake, weight gain, gain/feed, and relative organ weight, and promoted the activities of alkaline phosphatase and Cu-Zn superoxide (P < 0.05) by 84.17% and 49.86%, respectively, when compared with the control group. It also led to higher hepatic metallothionein content and tissue zinc concentration (P < 0.05) than in the control group. Furthermore, the concentrations of insulin and neuropeptide Y (NPY) in the 3000 mg/kg group were increased (P < 0.05) by 55.19% and 26.53%, respectively, compared to the control group. The present study suggests that pharmacological dietary supplementation of zinc increased growth performance, activities of enzymes, tissue zinc concentrations, and plasma insulin and NPY concentrations. Key words: Zinc, growth performance, tissue zinc concentration, enzyme activity, hormone concentration, piglet

Slab Waveguide Sensor Based On Amplified Phase Change Due To Multiple Total Internal Reflections, Sofyan A. Taya, Taher M. El-Agez
Turkish Journal of Physics
We present theoretically an optical slab waveguide sensor based on amplified phase change due to multiple total internal reflections (TIRs). Compared with the conventional waveguide sensors, the proposed approach provides higher sensitivity. In this sensor, we adopt the change in the ellipsometric total phase change \Delta as the measuring probe of changes in the refractive index (RI) of the cladding. The change in \Delta is calculated for large number of alternating total reflections. Numerical calculations show that \Delta is strongly dependent on the RI variations of the cladding. Moreover, theoretical simulations show that the resolution of this sensor is predicted …

Symmetry And The Order Of Events In Time. A Proposed Identity Of Negative Mass With Antimatter, Randy Wayne
Turkish Journal of Physics
In another paper in this series, we developed a symmetrical theory of mass which describes how systems of positive mass and negative mass will respond to an input of thermal energy. A system composed of positive mass or negative mass will respond to an input of thermal energy in opposite ways. For example, if a system composed of positive mass expands in response to radiation from a hot body, a system composed of negative mass will contract. Likewise, if the system composed of positive mass contracts when brought in communication with a cold body, a system composed of negative mass …

Near-Resonant Diurnal Reactions: A Physical Model Applicable To Origin Of Life Processes, Eddwin Budding, Cüneyt Aki, Osman Demi̇rcan, Bülent Gündüz, Güngör Gündüz, Mehmet Emi̇n Özel
Turkish Journal of Physics
We adopt that the large residual chemical potential energy (CPE) among reagents of the biosphere constitutes the key physical problem posed by life. We associate the formation of this CPE with the near-resonant behaviour of a two-stage `A-B' molecular process that behaves as a self-sustaining parametric oscillator. Under suitable conditions, such an oscillator generates CPE when forced by a periodic (daily) insolation. The net growth factor required to explain the current mean excess of biospheric CPE is \sim 5 x 10^{-12} d^{-1}. This aligns with the mean exponential coefficient of secular oxygen generation in the terrestrial atmosphere. It is also …
