Limit your outdoor exposure during these times and use an air-conditioner.

The sample on the left had been placed in an outdoor exposure rack, and weathered for a total of 6 years.

Besides exhibition was first published outside the pavilion 57 - with the opening of outdoor exposure.

Photooxidation accounts for most polymer failures that occur during outdoor exposure.

The natural outdoor exposure in Great Britain ranges from 2 to 4 nSv/h (nanosieverts per hour).

The building was dismantled in 1978 and most of the panels retained their original strength with the exception of paperboard which is unsuited to outdoor exposure.

For routes which have significant outdoor exposure GPS units have proven to be a far more effective means of tracking security and law enforcement patrol behavior.

Vitamin D is produced in the body when ultraviolet rays from the sun hit the skin; outdoor exposure is needed because UVB radiation does not penetrate glass.

The largest limitation in using PC technology is that the materials cannot be made stable enough to withstand thousands of hours of outdoor exposure so long-term outdoor applications are not appropriate at this time.

Markings placed on stainless steel are extremely durable and have survived such testing as abrasion resistance, chemical resistance, outdoor exposure, extreme heat, extreme cold, acids, bases and various organic solvents.

Although rickets and osteomalacia are now rare in Britain, there have been outbreaks in some immigrant communities in which osteomalacia sufferers included women with seemingly adequate daylight outdoor exposure wearing Western clothing.

But Dr. Shelley Sekula-Rodriguez, a dermatology professor at the Baylor College of Medicine in Houston, said a series of studies have concluded that indoor tanning may be just as harmful as outdoor exposure.
