Apparatus for calibration of a uroflowmeter.
A device has been constructed in order to obtain a flow analogous with the flow during micturition. Sources of error with instruments used in connection with micturition analysis can be determined by using this apparatus.
Micturition studies in infants and children. Technique.
A method for simultaneous and continuous registration of bladder pressure and urine flow is presented. It has been tested in infants and children of various ages. The sources of error and the reliability of the method are analysed. The pressure is measured via a suprapubic bladder puncture. The urine flow is converted into gas flow, which is registered by a pneumotachograph. The method is accurate enough for it to be used even in infants.
The Colours and Dresses of Racism in America
The monograph argues that American racism has two colours (white and black), not one; and that each racism dresses itself not in one clothing, but in four: (1) “Minimal” negative, when one race considers another race inferior to itself in degree, but not in nature; (2) “Maximal” negative, when one race regards another as inherently inferior; (3) “Minimal” positive, when one race elevates another race to a superior status in degree, but not in nature; and (4) “Maximal” positive, when one race believes that the other race is genetically superior. The monograph maintains that the needs of capitalism created black slavery; that black slavery produced white racism as a justification for black slavery; and that black racism is a backlash of white racism. The monograph concludes that the abolition of black slavery and the civil rights movement destroyed the social and political ground for white and black racism, while the modern development of capitalism is demolishing their economic and intellectual ground.
