Preferential solvation of indomethacin and naproxen in ethyl acetate + ethanol mixtures according to the IKBI method

Physics and Chemistry of Liquids, 2013
The preferential solvation parameters of indomethacin and naproxen in ethyl acetate + ethanol mixtures are derived from their thermodynamic properties by using the inverse Kirkwood–Buff integrals method. It is found that both drugs are sensitive to solvation effects, so the preferential solvation parameter, δxEA,D, is negative in ethanol-rich and ethyl

Türkiye-Irak Kürt Bölgesel Yönetimi (IKBY) İlişkilerinde Güvenliksizleştirmeler: 2008-2016 Arası Dönem

Çanakkale Onsekiz Mart Üniversitesi Uluslararası Sosyal Bilimler Dergisi, 2018
Türkiye, inşa ettiği kimlik ve ulus devlet anlayışına potansiyel tehdit ürettiği gerekçesiyle Irak Kürt bölgesiyle olan ilişkilerinde cumhuriyetin kuruluşundan itibaren güvenlik odaklı bir ilişki biçimi benimsemiştir. 1980’lerde PKK’nın Irak’ın kuzeyine yerleşerek Türkiye’ye saldırılar gerçekleştirmesi ve daha sonraki süreçlerde Ortadoğu bölgesindeki ...
