Logistics systems and related decisions are of vital importance in making supply chains effective, efficient and without disruption. Logistic pressure factors may emerge at different points along the logistics process, and given the role of logistics decisions as one of the important indicators of competitiveness, the determination of the logistics pressures that are likely to increase the costs of business, and their causative factors are a vital aspect of the logistics decision-making process. The study aims to provide assistance in the selection of the most ideal logistics decision by ranking the pressure factors affecting the logistics system, especially during the pandemic period for logistics enterprises operating in Ordu and Giresun provinces and which have a corporate identity.Design/methodology/approachIn this study, it is aime...

This study focused on the effect of resveratrol on these pathways. Materials and Methods: In this study, the rat crypt intestinal cell line (IEC-6) culture, an application of lipopolysaccharide or a cytokine mixture and a scratch migration assay model were used. Nitric oxide synthase-2 (iNOS) and cyclooxygenase-2 (COX-2), focal adhesion kinase (FAK) and its phosphorylated form (pFAK) levels were assessed. Results: IEC-6 cells covered 88% of the denuded area in the control, 54% in LPS, and 35% in cytomix groups at the 24 th hour. The treatment with resveratrol at doses of 0.5, 1 and 5 µM/L before LPS resulted in the repair of 84%, 87% and 76% of the denuded areas, respectively. Likewise, with cytomix, it was 86%, 82%, and 78%. Resveratrol at a dose of 5 µM/L prevented an increase in iNOS levels. All three doses of resveratrol were effective in preventing increases in COX levels. FAK or pFAK expressions remained unchanged in all groups. Conclusion: Resveratrol, being known for its antioxidant features, suppresses excessive inflammatory response and helps preservation of mucosal integrity by conservation of epithelial restitution.

Large, and also frequent, earthquakes are triggered by the influence of the westward moving Anatolian platform along the North Anatolian Fault Zone (NAFZ) and the extensional part of the Aegean plate which combine to form a transtensional tectonic regime. The apparently rigid character of the Black Sea oceanic lithosphere also provides a simple explanation for the deviation of the NAF (North Anatolian Fault) from the small circle path in western Turkey. The depth of the crust-mantle boundary is expected to be around 30 km or less in the Marmara sea region. This boundary is around 20 km in the Western Black sea. Along the southern Black sea margin a passive margin sedimentary prism developed during the post-arc period since the Maastrichtian. Owing to the compressional regime affecting the region after the closing of the Intra-Pontide Suture most of the Western Pontides were uplifted during the Late Eocene. ...

Modal parameters were extracted from three ambient vibration tests carried out over the period since the bridge came into service. The bridge became operational in 2009, and experimental measurements were taken in 2010, 2019, and 2021. The Enhanced Frequency Domain Decomposition (EFDD) method in the frequency domain and the Stochastic Subspace Identification (SSI) method in the time domain were used. Modal parameters were compared and any differences found over time in the measurement test results were investigated. Comparison of the results shows that changes in the natural frequencies were very limited and there was no change between the mode shapes. When experimental natural frequencies were compared, the maximum difference between the first and second measurements was calculated as 2.827%. Similarly, the maximum difference between the first and third measurements was 5.587% for the second mode, and around 3% for the other modes. This result is as expected because: (i) the bridge is not subject to heavy vehicle traffic and only connects village roads; (ii) no significant earthquake occurred during this period in the region which might have caused structural damage; (iii) no corrosion was found in the structural system elements as there was no contact with the reservoir water; (iv) no settlement or sliding occurred in the ground and boundary conditions remained unchanged. Moreover, the fatigue behavior of the bridge was investigated using the stress life method and AASHTO LRFD Bridge Design Specifications. To rationalize the results against the fatigue effects, the verified finite element model was used. From the fatigue analyses, it was concluded that the fatigue life of the bridge was within safe limits.

Besides, it focuses on teaching in religion schools. Protestant movement, which began in Germany in 1520s, revealed phenomenon of training teachers who were not from clergy. Such teacher training efforts initiated after the 1670s revealed two teacher training institutions called "Seminar" and "Normal" schools. The 18th century was a period in which the modern teacher education spread out in all countries. On the other hand, the formation of nation-states began. In the 19th century, teachers became away from the church, and after the salary given by the state, they separated from public's wishes and orientation and completely attached to the state. States, with completely taking inspection system from churches, began to provide "state education" to form a new human being (Bildung) and to use education as a tool for social integration and economic development. They get the most support from teachers they trained and gave salary. The 20th century was the period of planning and implementation of teacher education in higher education.

It was found from the interpretation of seismic reflection data (Finetti et al., 1988) that it is quite evident that the lower part of the southern margin of the W-Black Sea basin generally preserves the extensive tectonics associated with the rift process that generated the Black Sea. On the contrary, the middle-upper margin is affected by fully evident compressive tectonics accompanied by overthrusts. Frequently the compressive deformation was superimposed on preexisting distensive faults (in many cases evidently of listric type) which commenced their activity in the Upper Cretaceous or at the end of the Mesozoic and frequently continued into Paleocene.

South of this zone, lie the Iskenderun, Latakia, and Mesaoria Basins, together with the outer part of the Antalya Basin. South of the AmanosLarnaka Fault Zo ne lays the Cyprus Basin. South of the Tartus Ridge lies the Levantine Basin on the northern margin of the African plate. The Structure of the Eastern Mediterranean from the Gravity Data The Eastern Mediterranean Sea is dominated by elongated NESW trending depressions, known as the Herodotus Abyssal Plain, with Bouguer gravity maximum of approximately 220 mGal. Due to the increasing sediment thickness to the east the anomalies decrease eastwards and range between 80 and 20 mGal for offshore Israel and Lebanon. Eratosthenes Seamount is a continental fragment with crustal thickness of 24 km. It does not exhibit a pronounced gravity expression, while Cyprus, with a continental crust of 30�32 km, has high positive Bouguer gravity values of approximately 130 mGal caused by overthrust ophiolites. The deep parts of the Levantine Basin and partly the Herodotus Abyssal Plain are covered by up to 15 km of thick sediments. The crust is oceanic and approximately 5 to 6 km in thickness, with abrupt transition to continental margin to the east indicating the existence of a shear zone.

The thickness of sediments in the Black Sea basin is in excess of 15 km, and contains high concentrations of metallic salts. The results of the sampling project carried out from the R/V K. PIRI REIS indicate the presence of elemental concentrations of Co: 25 ppm, Cr: 25 ppm, Cu: 34 ppm, Mo: 105 ppm, Ni: 128 ppm, Vn: 167 ppm, U: 13 ppm, Sr: 78 ppm and Mn: 500–1000 ppm, in the upper 60 cm of the sediment layer in certain horizons of the marginal areas. Magnetic data strongly suggest regional subsidence along the marginal areas. It is therefore very important to investigate the marginal areas extending from Istanbul to Sinop, in connection with anaerobic conditions of the Black Sea.
