The role played by angiotensin (1-7) in the regulation of renal haemodynamics and excretory function in anesthetized rats
Initial studies have demonstrated that intra- renal infusion of Ang (1-7) caused a diuresis and natriuresis that was proportional to the degree of activation of the Renin Angiotensin Aldosterone System (RAAS). This raised the question as why the magnitude of this diuresis and natriuresis was …

Development of fortified bakery products based on kokoro, a traditional Nigerian snack
… of Kokoro snack samples were produced by fortification of maize flour -fibersol-2-whey protein blends at 1% each with functional ingredients (ginger, fenugreek, turmeric, spirulina, and red paprika) and a final blend containing all the functional ingredients at 1% level each. The resultant kokoro …

An examination of parent-child interactions and developmental pathways of emotion regulation
<p>Research examining emotion regulation has indicated that children's success at home and school is enhanced through adaptive emotion regulation skills (Eisenburg, Spinrad & Morris, 2002). This is particularly true in the areas of social competence and academic functioning (Harris, Robinson, Chang …

Microphone suppression of air-noise on geophones
Air-noise in seismic records creates a loss in signal quality, reducing seismic image clarity. A microphone may be used to estimate and remove air-noise in seismic records. This thesis covers the characterization of air-noise on a prototype 4-Component geophone (3-C geophone plus microphone), as …
