ABS TRACTObjective: Viral hepatitis and HIV infection are important health problems. The aim of this study was to investigate seropositivity of HBsAg, Anti-HBs, Anti-HCV and Anti-HIV in the patients who were admitted to Artvin State Hospital between October 2009 and October 2012. Materials and Methods: Blood samples from the patients are analysed in Abbot Architect İ 1000 (Abbott Laboratories, İllinois,USA) using chemiluminescence method. Results: Serologically 21865 patients are tested for HBsAg, 15284 patients are tested for Anti-HBs, 21330 patients are tested for Anti-HCV and 17935 patients are tested for Anti-HIV. In our study 3.96%, 35.06%, 0.85% and 0.05% of the patients are tested are found to be seropositive for HBsAg, Anti-HBs, Anti-HCV and Anti-HIV respectively. Conclusion:The results detected for seropositivity in Artvin are similar to those found in other regions of Turkey.

Following a meticulous protocol, our study results provide up-to-date and more stringent BV estimates of global hemostasis tests.

Corrosion of metallic structures is a serious problem in most industries worldwide. This problem can be controlled by the addition of chemicals capable of adsorption onto the metal surface. The metal can be isolated from the corrosive environment. These chemicals are often selected from groups containing free electron pairs and / or π electrons, which are rich in functional groups. In this study, electronic structures Highest Molecular Orbital (HOMO), Lowest Occupied Molecular Orbital (LUMO), MEP, energy gap (ΔE), ionization potential (I), electron affinity (A), chemical structure of pyrimidine derivative compounds containing unpaired electron pairs, π electrons, functional groups such as N, O and S hardness and softness (S), general electrophilic index (ω), transmitted electron fraction index (ΔN) and recovery (backEbackdonation) properties of quantum chemical calculation methods to investigate the properties of the selected compounds in this direction and adsorbed to the surface with the quantum chemical calculation methods. The aim of this study is to determine the efficiency of synthesized compounds as anticorrosion materials and to provide new gains to the industry in this sense.
