or Marburg hemorrhagic fevers - "These viruses are normally in bat
populations...Viruses are jumping over from natural animal reservoir hosts
into the human population, & they're causing these large emerging disease
problems... Another example would be Nipah, a disease that emerged in
Malaysia in the mid-90s. This was a disease 1st seen in pigs...For Marburg
virus, this is really a story that goes back to the 1960s. That virus was
actually discovered by an outbreak of hemorrhagic fever in facilities in
Europe, in Germany & Yugoslavia. These facilities were importing African
green monkeys from Uganda &
then using the tissues of these animals as part of vaccine production."
Now we have a reverse problem of people's diseases infecting wildlife,
esp. due to careless disposal of waste & having no (insufficient)
buffer zones between species.
http://www.xenex.com/xenex-robot/ - pesticidal device - "Not only is
the pulsed xenon pulse more intense, it also contains
wave-lengths of germicidal UV. It is known that
are susceptible to UV damage in the range of 200 to 280 nanometers.
Pulsed xenon produces wavelengths across this range whereas as mercury
vapor systems are narrow spectrum & only produce UV at 253.7
Because our pulse contains higher energy wavelengths, the
Xenex system damages cell walls, cellular structures as well as
UV at 260-265 nanometers, which mirrors peak DNA/RNA absorbency...
Pulsed xenon disinfection was developed in the late 1970s and represents
an advance over the earlier mercury vapor systems
(note: if it is not pulsed xenon, then the system uses mercury lamps)."
How UV Disinfection Works
- "High-energy ultraviolet light in the area of the spectrum known as UV-C
is produced by our xenon gas lamps. This UV-C energy passes through the
cell walls of bacteria, viruses &
Once the UV-C energy
is inside the microorganism, it is absorbed by the DNA, RNA & proteins.
One of the primary mechanisms of damage created by UV-C is the fusing of
the strands of DNA, creating what is known as 'thymine dimers.'
the DNA is fused, the organism can no longer replicate & is, therefore, no
The technical term for this is 'deactivation'"
"The 4 primary types of (bacteria/ virus/parasite) cellular damage caused
by Pulsed Xenon UV are photo-hydration
molecules into the DNA to prevent its folding),
(breaking the backbone of the DNA),
(DNA damage that prevents
cross-linking (cellular wall damage that causes cells to lyse)."
(Here we see 2 scientific principles in
operation - fast/shrill/high vibration that damages insect cell walls, + the UV light that
Pulsed-Xenon UV Lamp
- Using a
Xenon bulb, a powerful,
non-mercury form of UV light, combined with a pulse technology that
generates high intensity pulses, which makes Xenex the most powerful
form of UV-C.
Visible Light Filter - Blocks the bright
Safety Features - Built in safety timer, emergency stop button,
automatic shutdown motion detection system.
(Thus to operate in vacant rooms/environment.)
