Nuclear polyhedrosis viruses such as the one isolated from the celery looper, Anagrapha falcifera (Kirby) (AfMNPV), have the potential to be successful bioinsecticides if improved formulations can prevent rapid loss of insecticidal activity from environmental conditions such as sunlight and rainfall. We tested 16 spray-dried formulations of AfMNPV to determine the effect of different ingredient...

Citalopram (CIT), 1-(3-dimethylaminopropyl)-1-(4-fluorophenyl)-5-phthalancarbonitrile, a selective serotonin reuptake inhibitor, is one of the most widely used antidepressants for the treatment of anxiety, obsessional, and control disorders. The degradation of the pharmaceutical CIT hydrogen bromide in water was investigated in the dark and in a growth chamber outfitted with fluorescent lamps s...

This work aims studying the photochemical behaviour of octylphenol (OP) in aqueous solution exposed to simulated UV solar radiation, in lab-scale experiments. The OP photolysis was also investigated by varying different reaction parameters such as: initial pH, initial concentration of OP, reaction temperature, concentration of hydrogen peroxide, presence/absence of dissolved organic matter, HCO...

seven geographic isolates of helicoverpa armigera npv were characterized by pcr-rflp techniques and their comparative virulence to second instar larvae of h. armigera (hã¼bner) were compared before and after exposure to simulated sunlight as well as open weather conditions on cotton and tomato plants. the pcr products of 25k fp region showed no difference among the isolates (780 bp). the pcr am...

To investigate the role of nucleotide excision repair (NER) in the cellular processing of carcinogenic DNA photoproducts induced by defined, environmentally relevant portions of the solar wavelength spectrum, we have determined the mutagenic specificity of simulated sunlight (310-1100 nm), UVA (350-400 nm), and UVB (290-320 nm), as well as of the "nonsolar" model mutagen 254-nm UVC, at the aden...

This paper presents the integration of urban planning techniques considering sunlight access to an existing simulator of urban plots building potential, BlockMagic. Insolation can be simulated along with Master Plans rules, aiming at maximizing both building potential and sunlight access.

Two lamps, including simulated sunlight lamp and UVA-365 nm lamp, were used to study the kinetics and changes of component distribution of NPEOs mixture in solution during photodegradation, as well as the effect of H2O2 on the photodegradation. LC-MS was used to analyze the products of NPEOs photodegradation. It was found that photodegradation of NPEOs occurred under both simulated sunlight and...

1. Sunlight ultraviolet (UV) exposure can be highly damaging to biological tissues, being known to cause cellular damage and immunosuppression in humans and rodents, and depletion of carotenoid-based sexual plumage coloration in birds (i.e. photobleaching). However, it remains unknown whether sunlight may cause photobleaching in living tissues that comprise sexual signals such as bare parts in ...
