Yes, partly. Plants already have reasonable UV shielding; for most plants only a small proportion of the UV-B radiation striking a leaf actually penetrates very far into the inner tissues. Also, when exposed to an enhanced UV-B level, many species of plants can increase the UV-absorbing pigments in their tissues. Other adaptations include increased thickness of leaves which reduces the proportion of inner tissues exposed to UV-B radiation.

Possibly. Amphibian populations are in serious decline in many areas of the world, and scientists are seeking explanations for this. Most amphibian population declines are probably due to habitat destruction or habitat alteration. Some declines are probably the result of natural population fluctuations. Other explanations for the population declines, as well as the reductions in range of habitation, include disease, pollution, atmospheric changes and introduced competitors and predators.

Ultra Violet Light Detector: Ultraviolet light is used to detect the range of invisible radiation wavelengths shorter than violet in the invisible spectrum. Here is how it works: with advances in copier and laser printing technology, it has become easier than ever to create high-resolution replications of a wide range of currency. The UV detector works like X-Ray vision to zone in on questionable areas. See similar questions...

The earlier units only had 1/4" inputs and outputs. Inputs are fully balanced, outputs are single-ended (some say "quasi-balanced") auto balancee/unbalanced. Ability to drive longer cables is less and high frequency rolloff can be a concern due to cable capacitance. Around 1994 we updated the design and changed to the "B" designation. These units have fully balanced inputs and outputs, both XLR and 1/4" TRS connections being utilized. Functionally the units are virtually identical. See similar questions...

Hepatitis A (HAV) is caused by a virus found in feces (people's stool). You can get it by coming in contact with infected feces. The most common way is by swallowing food or liquids that get contaminated by hands that are not washed thoroughly after using the toilet. You can also get Hepatitis A through sexual acts like 'rimming' (licking someone's anus) or via oral sex on a male's penis after he has had anal sex. See similar questions...

UV and non-UV are abbreviations for the kinds of coating used on our paper. Here are some of the core differences and applications: UV (Ultraviolet Coating) is a clear liquid spread over the paper like ink and then cured instantly with ultraviolet light. UV coating gives more protection and sheen than either varnish or aqueous coating. Since it is cured with light and not heat, no solvents enter the atmosphere. See similar questions...

The evidence is strong. The earliest experimental evidence that UV-B radiation causes skin cancer was acquired with animals; in humans there was a clear association between sun exposure and skin cancer, but that did not point specifically to UV-B. In recent years the advancement of molecular biology has provided us with analyses that produce direct evidence that genetic alterations found in human skin carcinomas are indeed caused by UV-B radiation.

Not always. Sunscreens applied to human skin limit the penetration of UV radiation into the skin, and thus sunburn can be prevented. Sunscreens were primarily developed for this purpose. The effectiveness of sunscreens in protecting against skin cancer and immune suppressions is under debate. Any effectiveness in these respects may well be lost if the sunscreen is used to stay out in the sunlight longer than would be done without the sunscreen. See similar questions...

Ultraviolet (UV) light is at the invisible, violet end of the light spectrum. Even though we can't see UV light, we are exposed to UV rays from all light sources, including the sun. See similar questions...

There are some UV-B-sensitive varieties of crops that experience reductions in yield. However, there are also UV-B-tolerant varieties, providing the opportunity to breed and genetically engineer UV-B tolerant varieties. For commercial forests, tree breeding and genetic engineering may be used to improve UV-B tolerance. For unmanaged or natural forests, these methods are not an option. See similar questions...

Our Splashskins Unisuits use 80/20 nylon-spandex tricot, which holds its four-way stretch and moves any way the body moves. Other fabrics stretch only two ways, tightening under play conditions and don't hold up to wear as well.

Power is the rate of doing work. It is an instantaneous quantity, measured in watts. A watt is 1 joule per second. Energy is power over a period of time. It is measured in watt-seconds, but that unit is too small for everyday use, so the unit kilowatt-hours is more commonly used. Note this is a controversial subject - not because there is any disagreement, but because some people are either lazy, uninformed or misinformed and misuse the terms. See similar questions...

With a few exceptions (see "If I want outpatient data, what do I ask for?"), the Carrier dataset contains CMS1500 form claims related to services performed by physicians (non-institutional) that have been sent to carriers for payment. The Outpatient file contains UB-92 claims sent by outpatient institutions to fiscal intermediaries for payment. In the claims files, the residence information is recorded at the time of treatment.

All light is given off at different wavelengths. For example if you see a rainbow, you will notice that the colors are always in a specific order from red all the way to blue. You are able to see each color due to their individual wavelength. These wavelengths are part of the visible portion of the electromagnetic spectrum. UV light is at a wavelength of 254nm (nanometers), and is not visible to the naked eye. See similar questions...

UV dose is the energy that is coming off the UV lamp over a specific time period. Therefore, UV dose (or fluence) is a product of UV intensity and time. Dose is usually measured in milli joules per square centimeter. Each Sterilight system is rated to disinfect your water at specific flowrate, under specific water quality conditions to give a UV dose of 30 mJ/cm2 at the end of the lamp life (which is one year). If you were to run say 10 USGPM through a 5 USGPM Sterilight system (ie. See similar questions...

Projection-mapping takes your selected object, and attaches it to the surface of your target object. The selected object will be bent and distorted so that it matches the curves on the surface of the target object. Sort of like projecting an image on somebody's shirt. UV-mapping will take a group of selected objects, and map them along a curve, evenly spacing them along the length of that curve. See similar questions...

UV-B light is generally harmful to plants, but sensitivity varies widely and is not well understood. Many species of plants are not UV-B sensitive; others show marked growth reduction and DNA damage under increased UV-B light levels. It is thought that ozone depletion may not have a significant detrimental effect on agricultural crops, as UV-B tolerant varieties of grains could fairly easily be substituted for existing varieties.
