From reassurance to irrelevance: adolescent psychology and homosexuality in America.

American psychology by the 1920s contained a greater capacity for viewing some homosexual experiences as normal than most current historical literature suggests. Developmental psychologists agreed with psychiatrists that adult homosexuality was pathological, but they also agreed that adolescent sexual development included a homosexual phase. Until the late 1960s, developmental texts reassured parents and teachers that homosexual behavior among adolescents was transitory and quite normal.

Dietetic specialization: opinions of directors of departments of dietetics.

The need for specialists in dietetic practice was studied by surveying a stratified, random sample of 750 directors of departments of dietetics from nonfederal, general medical-surgical hospitals with more than 75 beds. The response rate was 72%. The majority of respondents were directors who considered themselves generalists.

Photosynthesis, Carbohydrate Metabolism, and Export in Beta vulgaris L. and Phaseolus vulgaris L. during Square and Sinusoidal Light Regimes.

Rates of photosynthesis, sucrose synthesis, starch accumulation and degradation were measured in sugar beet (Beta vulgaris L.) and bean (Phaseolus vulgaris L.) plants under a square-wave light regime and under a sinusoidal regime that simulated the natural daylight period.

Diurnal changes in allocation of newly fixed carbon in exporting sugar beet leaves.

Storage of newly fixed carbon as starch and sucrose follows a regular daily pattern in exporting sugar beet leaves under constant day length and level of illumination. Up to the final two hours of the light period, when starch storage declines, a nearly constant proportion of newly fixed carbon was allocated to carbohydrate storage, principally starch. Sucrose is stored only early in the light period, when there is little accumulation of starch.

Diurnal Pattern of Translocation and Carbohydrate Metabolism in Source Leaves of Beta vulgaris L.

Transitions in carbohydrate metabolism and translocation rate were studied for evidence of control of export by the sugar beet (Beta vulgaris L. Klein E.) source leaf.
