Socio-economic impacts of China Pakistan Economic Corridor (CPEC) at community level : case study of Gwadar Pakistan
2019
Master's thesis Global development and planning UT505 - University of Agder 2019 Development brings prosperity to the nations. The mega development projects such as sea ports, dams, infrastructures, railways, airportsetc. offerbetter employment opportunitiesand improved standard of lifein the country and gradually move the country from developing to developed States. At the same time, these mega projects forced people to leave their homes in the name of development. Development-induced displacements or forced evictions badly affect the socio-economic and socio-cultural aspects of the communities. Lack of adequate planning often make the affected people homeless and jobless for rest of their…
Fabrication, characterization, thermal stability and nanoassemblies of novel pullulan-aspirin conjugates
2017
Abstract Present study deals with homogeneous and one-pot synthesis of novel macromolecular prodrugs (MPDs) of aspirin onto naturally occurring hydrophilic biopolymer pullulan. Pullulan-aspirin conjugates were synthesized by using green carboxylic acid activating reagent 1,1′-carbonyldiimidazole (CDI). The aspirin was first reacted with CDI to prepare aspirin-imidazolide at RT for 24 h which in situ reacted with pre-dissolved pullulan and the reaction preceded further for 24 h at 80 °C under nitrogen. Degree of substitution (DS 0.32–0.40) of aspirin onto pullulan was calculated from 1H NMR spectroscopy. Spectroscopic techniques confirmed the high covalent drug loading and purity. Thermal an…
