third world intellectuals in v. s. naipaul’s fiction: the mimic men, a bend in the river, magic seeds

this thesis attempts to study the representations of the third-world intellectuals in three fictional works by the british-educated trinidadian nobel-winner v. s. naipaul: the mimic men, a bend in the river, and magic seeds. the first one recounts the story of ralph singh’s sense of alienation, his experiences as a colonial politician, and his struggle to give order to his disorderly world thro...

Measurement of single nephron filtration rate in the kidney of the river lamprey, Lampetra fluviatilis L.

1. The reliability of [3H]inulin as a reference substance for the measurement of glomerular filtration rate (GFR) in river lampreys was investigated. 2. Simultaneously measured renal clearances of [3H]inulin and [14C]-polyethylene glycol (PEG) were not significantly different. 3. Recoveries of [3H]inulin in the urine following its injection into the proximal tubule and urinary duct averaged 83....

Localization of ion-transport in the intestine of the migrating river lamprey, Lampetra fluviatilis L.

The intestine of the river lamprey, like that of teleosts, plays a major role in marine osmoregulation (Morris, 1958; Pickering & Morris, 1970). Monovalent ions from the ingested hyperosmotic environment can be transported across the intestine against a concentration gradient ultimately producing a net water flux from the gut lumen to the bloodstream. This water movement compensates for renal a...

A micropuncture study of kidney function in the river lamprey Lampetra fluviatilis adapted to sea water.

Micropuncture techniques have been used to investigate kidney function in lampreys adapted to hyperosmotic media. Plasma electrolyte concentrations were maintained well below corresponding concentrations in the external environment. Urine composition was variable, but generally showed high concentrations of magnesium, sulphate and chloride ions. Lampreys in 50% sea water produced urine which wa...
