The Power Of The Periphery: Aid, Mutuality And Cold War U.S-Ghana Relations, 1957-1966, Moses Allor Awinsong

Masters Theses

This project interrogates how economic self interest motivated periphery states such as Ghana to use foreign policy as a vehicle to attract improved development assistance from superpowers, in this case the United States. While the United States viewed its aid program in Ghana in stringently Cold War terms, Kwame Nkrumah and his advisors were less inclined to get deeply concerned about Cold War ideology. This project shows that Ghanaian agency was manifested in the Cold War through the new state's construction of a foreign policy image that made it a prominent African voice globally. It then examines how that image …

Formation Of The Ether Bridge In The Loline Alkaloid Biosynthetic Pathway, Minakshi Bhardwaj

Theses and Dissertations--Chemistry

Lolines are specialized metabolites produced by endophytic fungi, such as Neotyphodium and Epichloë species, that are in symbiotic relationships with cool-season grasses. Lolines are vital for the survival of the grasses because their insecticidal and antifeedant properties protect the plant from insect herbivory. Although lolines have various bioactivities, they do not have any concomitant antimammalian activities.

Lolines have complex structures that are unique among naturally occurring pyrrolizidine alkaloids. Lolines have four contiguous stereocenters, and they contain an ether bridge connecting C(2) and C(7) of the pyrrolizidine ring. An ether bridge connecting bridgehead C atoms is unusual in natural products and …
