Title: Sunlamp

Abstract

The purpose of this model was to facilitate the design of a control system that uses fine grained control of residential and small commercial HVAC loads to counterbalance voltage swings caused by intermittent solar power sources (e.g., rooftop panels) installed in that distribution circuit. Included is the source code and pre-compiled 64 bit dll for adding building HVAC loads to an OpenDSS distribution circuit. As written, the Makefile assumes you are using the Microsoft C++ development tools.

  • Normal human skin fibroblasts were exposed to either 0-5 J/m/sup 2/ of 254-nm ultraviolet (UV) radiation or 0-50 kJ/m/sup 2/ of the Mylar-filtered UV (>310 nm) produced by a fluorescent sunlamp. These cells were then incubated for 0-20 min in medium containing 10 mM hydroxyurea (HU) and 0.1 mM 1-..beta..-D-arabinofuranosyl cytosine (ara C), and the yield of DNA strand breaks was measured by means of the alkaline elution technique. For cells irradiated with 254-nm UV, which results primarily in the formation of cyclobutane pyrimidine dimers, a rapid increase in DNA strand breaks was detected following incubation with these metabolic inhibitors.more » In contrast, only a low level of strand breaks formed in cells incubated with HU and ara C after irradiation with approximately equitoxic fluences of sunlamp UV >310 nm, which mainly causes the induction of nondimer DNA lesions. Hence, these results are consistent with the conclusion that the pathways involved in the repair of nondimer DNA damages induced by UV wavelengths >310 nm differ from the repair of pyrimidine dimers.« less
  • In this study, a sensitive host cell reactivation (HCR) technique was used to examine the repair capacity for DNA damaged by sunlamp exposure in fibroblast strains derived from 5 normal individuals and 8 patients representing three different diseases associated with DNA repair deficiencies. Adenovirus type 2 (Ad 2) was exposed to radiation from a GE 275 W sunlamp and subsequently used to infect fibroblast monolayers. At 48 hr after infection, cells were scored for the presence of viral structural antigens (Vag) using indirect immunofluorescent staining. Previous reports using this technique showed a substantial reduction in the HCR of sunlamp-exposed Admore » 2 for infection of excision repair deficient fibroblasts from patients with xeroderma pigmentosum. In contrast, the HCR of Vag synthesis for sunlamp-exposed Ad 2 was in the normal range for the three ataxia telangiectasia, three Bloom's syndrome, and two Huntington's disease fibroblasts strains.« less
  • An inert coating of calcium pyrophosphate in finely-divided form is provided on the inner surface of the envelope of a fluorescent sunlamp underneath the phosphor layer to reduce the emission of undesirable shortwavelength ultraviolet radiation (190 nm to 260 nm region). The relative densities of the phosphor layer and undercoating of calcium pyrophosphate are so correlated that the ratio of short-wavelength ultraviolet radiation to erythemal radiation is maintained below a prescribed limit. The particles of calcium pyrophosphate are also larger than about 1 micron and are thus adapted to selectively absorb the undesirable short-wavelength radiations and provide an integral UV-filteringmore » means for the sunlamp.« less
  • This report presents the results of a customer telephone survey of the users of two software programs provided by the U. S. Department of Energy Federal Energy Management Program (FEMP) during calendar years 1995 and 1996. The primary purpose for the survey is to provide the Team Leader to FEMP Technical Assistance and members of the team with detailed customer feedback pertaining to how well selected FEMP software programs are being used and to identify areas for improvement. The information presented enables managers to see both the strengths of their software programs and software components that can be improved. Themore » survey was conducted during the fall of 1997 in conjunction with a FEMP workshop attendee survey. The results of the workshop survey are presented is a sister document entitled, ''An Evaluation of the Federal Energy Management Program's Technical Assistance Workshops.« less
