1. When dilute aqueous emulsions of radioactive cholesterol are exposed to daylight, extensive photolysis may take place. This results chiefly in the formation of substances more polar than cholesterol, some of which are probably acidic. Substances less polar than cholesterol are formed to a smaller extent. Photolysis is greatest when the emulsions are strongly acidic or strongly alkaline. 2. P...
The study demonstrated that during the period of milking, the duration of the daylight had a significant effect on the lactation parameters in ewes lambed in January and June. Marked differences were noted in the levels of milk production in sheep, during the period of shortening daylight, i.e. in autumn, as the sheep lambed in June produced 50% less milk than ewes lambed in January. The dwindl...
This paper describes the development of a technique for extrapolation of dynamic daylighting simulations from a limited number of high dynamic range photographs. This technique allows us to photographically capture and measure per-pixel lighting quantities from existing spaces in a limited time frame; and the measured information is used to establish a statistics based daylight coefficient mode...
To evaluate the performance of buildings in use and to predict performance during design, it is necessary to identify what the appropriate measures of performance should be, when and how measures should be collected, and how results will be interpreted to determine success or failure. As noted in Chap. 1, one of the central barriers to effective daylighting is that daylighting performance is of...
Apie Lauryno Peluričio disertaciją „Ola ir dvi saulės. Filosofija sovietų Lietuvoje (1944–1986). Institucijos, asmenybės, idėjos“ jos gynimą / On Laurynas Peluritis’ Thesis „The Cave and Two Suns. Philosophy in Soviet Lithuania Institutions, Personalities, Ideas“
Time-series measurements of daylight (skylight plus direct sunlight) spectra beneath overcast skies reveal an unexpectedly wide gamut of pastel colors. Analyses of these spectra indicate that at visible wavelengths, overcasts are far from spectrally neutral transmitters of the daylight incident on their tops. Colorimetric analyses show that overcasts make daylight bluer and that the amount of b...
