This paper presents the relationship between daylighting performance and shading device design in the perimeter area of buildings. In the area of tropic and sub-tropic, designers always face with the contradiction between solar heat gain and daylighting using. Factors such as different type of shading device, material reflectance, fenestration design, opening ratio, and daylight distribution wi...

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...

nifedipine (nif) a 1, 4-dihydropyridine calcium channel antagonist, undergoes photodegradation to nitroso analogues of dehydronifedipine (ndnif) when exposed to sunlight. photodegradation products of nif have no clinical activity, so different formulations of nif must remain unchanged. if nif preparations become unstable in exposure to light, they could cause therapeutic failure. the present st...

This paper analyzes the effects of daylight and daylight saving time (DST) on pedestrian and motor vehicle occupant fatalities in the United States. Multivariate analyses of county level data from the Fatality Analysis Reporting System for 2-week periods in 1998 and 1999 are used. Results show that full year daylight saving time would reduce pedestrian fatalities by 171 per year, or by 13% of a...

conclusions recent treatment, in addition to age, gender and daylight duration were proved as strong independent determinants on bat development and the level of metabolic activity at [18 f] dg pet/ct and should be considered as an important confounding factor in future researches. results one-hundred eighteen studies were recognized to demonstrate foci of fdg bat uptake (3.1%, mean age: 22.7 y...

Seasonal blood pressure (BP) changes have been found to be related to either outdoor or indoor temperature. No information regarding the independent effects of temperature measured proximally to the patient, the personal-level environmental temperature (PET), is available. Inclusion of daylight hours in multivariate analysis might allow exploring the independent interaction of BP with seasonali...

The treatment of superficial skin lesions via daylight activated photodynamic therapy (PDT) has been explored theoretically with three dimensional (3D) Monte Carlo radiation transfer simulations. For similar parameters and conditions, daylight activated PDT was compared to conventional PDT using a commercially available light source. Under reasonable assumptions for the optical properties of th...

The paper describes the design, the implementation of a neural controller used in an automatic daylight control system. The automatic lighting control system (ALCS) attempt to maintain constant the illuminance at the desired level on working plane even if the daylight contribution is variable. Therefore, the daylight will represent the perturbation signal for the ALCS. The mathematical model of...
