Mobil robotun kinematik modeli cikarilmis, PID ve Parcacik Suru Optimizasyon (PSO) kontrol algoritmasi hakkinda bilgi verilmistir. PID katsayi parametreleri PSO kullanilarak belirlenmistir. Ziegler Nichols (ZN) ile bulunan PID katsayilari ile katsayilari PSO ile bulunan PID kontrolunun karsilastirilmasi yapilmistir. Katsayilarin PSO ile belirlenmesinden sonra optimum parametrelerin bulundugu gozlemlenmistir.

In total, 32 native apple accessions from four regions within the province were tested under greenhouse conditions by inoculating the shoot tips with pathogenic bacterium. Shoot tips were wounded for inoculation. Genotypical susceptibility index (GSI%) values were computed

However, its protective effects on intestinal tissue against ischemia reperfusion injury are unclear. We aimed to determine whether NS prevents intestinal ischemia-reperfusion injury in rats. Thirty rats were divided into three groups as sham (group 1), control (group 2), and NS-treatment group (group 3). All rats underwent intestinal ischemia for 60 min followed by a 60-min period of reperfusion. Rats were intraperitoneally infused only 0.9% saline solutions in group 2. Rats in the group 3 received NS (0,2 mL/kg) intraperitoneally, before ischemia and before reperfusion. Total antioxidant capacity (TAC), catalase (CAT), total oxidative status (TOS), oxidative stress index (OSI), and myeloperoxidase (MPO) in ileum tissue were measured. Also, ileum tissue histopathology was evaluated by a light microscope. The levels of liver enzymes in group 3 were significantly lower than those in group 2 (p <.01). TAC and CAT activity levels in ileum tissue were significantly higher in group 3 than in group 2. TOS, OSI, and MPO in ileum tissue were significantly lower in group 3 than group 2 (p <.05 for TOS and MPO; p < .01 for OSI). Histological tissue damage was milder in the NS treatment group than in the control group. Our results suggest that NS treatment protected the rat's intestinal tissue against intestinal ischemia-reperfusion injury.

Unfortunately, this potential is too frequently felt, in that unethical organizational practices are very commonplace. This article explores what accounts for unethical actions in public organizations, more specifically, why public servants commit those unethical practices from the points of view of employees and citizens, taking The Turkish Customs Authority as a case study. It presents the results of a survey of practicing employees of a Turkish public organization and service using citizens. The survey aimed to explore the perceptions of both employees and service users on the reasons of unethical behavior in Turkish custom service workplaces.
