Calendrical Tabulations - 1900 - 2200

Determination of urinary constituents in solutions by least-squares resolution of ultraviolet spectrums.

Least-squares resolution of ultraviolet (UV) spectrums has been tested as a method for determining the concentration of each UV-absorbing urinary component in a multicomponent solution. The tests reported here involved solutions containing 4-12 components chosen from 17 reference materials: p-aminobenzoic, anthranilic, ascorbic, ferulic, hippuric, p-hydroxybenzoic, uric, vanillic, and xanthuren...

Running head: SAVANT CALENDRICAL KNOWLEDGE 1 The structure of savant calendrical knowledge

Do calendrical savants use calculation to answer date questions? A functional magnetic resonance imaging study.

Calendrical savants can name the weekdays for dates from different years with remarkable speed and accuracy. Whether calculation rather than just memory is involved is disputed. Grounds for doubting whether they can calculate are reviewed and criteria for attributing date calculation skills to them are discussed. At least some calendrical savants possess date calculation skills. A behavioural c...

A date to remember: the nature of memory in savant calendrical calculators.

BACKGROUND Savant calendar calculators can supply with speed the day of the week of a given date. Although memory is suggested to be an important component of this unusual ability, memory function has never been systematically investigated in these skilled yet learning impaired individuals. METHODS Eight savant calendrical calculators, most of whom had autism, were compared with eight verbal ...

Trends in Mortality Among Females in the United States, 1900–2010: Progress and Challenges

INTRODUCTION We analyzed trends in US female mortality rates by decade from 1900 through 2010, assessed age and racial differences, and proposed explanations and considered implications. METHODS We conducted a descriptive study of trends in mortality rates from major causes of death for females in the United States from 1900 through 2010. We analyzed all-cause unadjusted death rates (UDRs) fo...
