Blue light special in a red light district

Blue light special in a red light district.

A study comparing sexually transmitted infections and HIV among ex-red-light district and non-red-light district sex workers after the demolition of Baina red-light district.

OBJECTIVES In June 2004, the red-light area of Goa was demolished. We compare HIV and sexually transmitted infections (STIs) between sex workers who had been based in Baina red-light district (ex-RLD-SWs) with sex workers who had never worked in Baina (non-RLD-SWs). METHODS Three hundred twenty-six sex workers recruited using respondent-driven sampling, completed interviewer-administered ques...

Ethylene is not involved in the blue light-induced growth inhibition of red light-grown peas.

Although the growth of intact plants is inhibited by irradiation with blue light, the growth rate of isolated stem segments is largely unaffected by blue light. We hypothesized that this loss of responsiveness was a result of ethylene production as part of the wounding response. However, we found no interaction between ethylene- and blue light-induced growth inhibition in dark- or red light-gro...

Red, Green, and Blue LEDs for White Light Illumination

The rapid improvement of the white light efficacy achievable with light-emitting diodes (LEDs) opens up new opportunities in the general illumination market. An LED light source made of red, green, and blue LEDs (RGB-LEDs) can provide the unique feature of color variability, allowing the user to select the desired color point of the lamp. The white light color accuracy required in the general i...

Green-light supplementation for enhanced lettuce growth under red- and blue-light-emitting diodes.

Plants will be an important component of future long-term space missions. Lighting systems for growing plants will need to be lightweight, reliable, and durable, and light-emitting diodes (LEDs) have these characteristics. Previous studies demonstrated that the combination of red and blue light was an effective light source for several crops. Yet the appearance of plants under red and blue ligh...
