Long wave, hand held, portable model for detection of fluorescence of stamps and tagging on currency or phone cards.
All microorganisms can be effectively destroyed by UV light in the 200-315 nm region, resulting in their loss of ability to infect humans, animals, food and plants. Savings on space and reduced maintenance costs, as no chemicals are introduced into the water. The UV section of the electromagnetic spectrum is compounded by three main wavelength ranges) UVc,UVb,UVa,( which have different effects on the DNA, RNA and proteins within the pathogen’s cell.
UV light also induces photochemical reaction in proteins, enzymes and other molecules) in the range of 240 and 280 nm) to ensure complete destruction. Research work and accumulated experience suggest that UV medium–pressure lamps cause permanent and irreversible inactivation of faecal bacteria like Escherichia coli.
Treatec21’s UV technology uses medium-pressure lamps and amalgam lamps, combined with a state-of-the-art quartz reactor providing an highly efficient and a high-density radiation profile which ensures permanent and irreversible inactivation of all relevant pathogens, including Escherichia coli.
Today, modern wastewater plants are designed using close pipes rather than the traditional open channel systems, while due to environmental considerations the use of contact tanks is no longer necessary. Closed-loop systems save floor space, prevent algae growth, protect the operators and enables flexible flow design and operation. The UV lamps incorporated in Treatec21‘s system are positioned perpendicularly to the flow ,forcing the microorganisms to pass through the area of lamps close to or in the high intensity zone.
It’s inner structure is based on quartz tubes with a special configuration that trap the light by using a mirror effect. This unique effect of the structure enables to increase the density in the field of radiation and therefore achieving higher efficiency of the reactor.
The system includes UV intensity sensors mounted onto the lamp arrays, thus providing measured intensity values.
The energy control unit enables to receive the required UV dose with the lowest energy input.
The system includes an automatic cleaning mechanism to prevent fouling of the quartz sleeves. The AOR is an efficient reactor consisting of high intensity medium pressure ultra-violet lamps, housed in an advanced optical reactor providing a reflective surface that traps the UV light and increases the effectiveness of the AOP. Advanced oxidation process is a novel technique to produce hydroxyl radicals by direct photolysis of hydrogen peroxide under UV radiation. The hydroxyl radical (HO*) is among the strongest oxidants found in nature and in the “chemist’s toolbox”. The full range of electromagnetic waves, arrange orderly in their wavelengths and frequencies is called the electromagnetic spectrum.

It’s one of the great paradoxes of life: what we perceive as beautiful has a tendency to be bad for us.
A person’s natural skin color is determined by the concentration of a pigment called melanin in the skin. UV radiation is a carcinogen; it causes mutations in your DNA that your body has to repair before new cells are made in order to prevent cancer from developing. If you are currently frequenting your local tanning salon or laying out and lathering yourself in baby oil, the best thing you can do is stop cold turkey.
Unfortunately, despite the nonsensical banter from politicians and TV personalities, skin cancer remains a formidable enemy in the US, affecting over 2 million people each year (4).
See your primary care doctor or dermatologist once a year for your annual skin exam as well as your regular skin care. Save yourself the frustration and utilize a curing dryer lamp with UV bulb to quickly and effectively dry your nails after they are completed. Ultraviolet technology offers a proven and accepted, environmentally friendly method for wastewater purification.
Whereas exposure to the same medium-pressure lamps cause also permanent deactivation of pathogenic E. In order to increase the process effectiveness, a medium-pressure lamp whose spectral output matches the absorption characteristics of the H2O2 is used. In order to maximize the reactors efficiency, the incoming water is pre-filtered and circulated via a reservoir. We should train them to do it!So this company Cyagen is paying authors for citations in academic papers.Fixing flaws in science must be professionalised.

Tan skin, while masking cellulite and stretch marks, is quite literally a sign of skin damage. When the skin is exposed to excessive amounts of UV radiation (with frequent sun or tanning bed exposure), the body can’t fix the mutations fast enough and skin cancer can develop. A sunburn is an immediate indication that the skin has been directly damaged by UV rays and is actively trying to repair that damage by increasing blood flow to the affected area (giving you a painful red hue). Research estimates that one in five Americans will develop skin cancer in their lifetime and, on average, twenty Americans die of skin cancer every day (1,6).
With a gel manicure this step is even more essential, as the UV light bulb is important for the manicure to set. If complete mineralization is achieved, the final products of oxidation are carbon dioxide and water.
If you need something urgently give us a call to check stock - Please have the item reference to hand as this will help to speed things up. While the number of melanocytes in the skin is fairly similar from person to person, the activity level of these cells when it comes to producing melanin varies greatly and is determined primarily by genetics.
Conversely, darker individuals have continuous production of eumelanin, naturally protecting them from UV DNA damage and lowering their incidence of skin cancer. While the production of melanin in the skin is influenced primarily by genetics, it can also be revved up temporarily in response to UV radiation.


For those who prefer to do their nails at home rather than head to a salon, you can enjoy the benefits of a curing dryer lamp as well. The activity of melanocytes is partially responsible for the wide spectrum of skin color that exists among humans.
Exposure to UV light causes an increase in Melanocyte-Stimulating Hormone (MSH), a hormone released from the brain. These lamps are available from a selection of reliable sellers on eBay, and are found in a range of prices and qualities. The release of this hormone into the blood stream revs up production of melanin by melanocytes in the skin, resulting in the golden brown skin color we call a tan. A landmark study that was published in the June 2010 issue of Cancer Epidemiology Biomarkers and Prevention determined that tanning bed users had a 74% increased risk of developing melanoma.
According to new data, every time you tan you put yourself at increased risk, no matter how old you are (7). LED Home Light.20W UV Black Spiral CFL Fluorescent Light Bulb - E26 FREE Shipping US Seller!!!
A UV replacement bulb for the lamp is also readily available, making maintenance on your unit simple. Eumelanin, the most abundant form of the compound, can be either black or brown and is associated with darker skin tones and suntans. The extra melanin from a suntan is supposed to protect cells from further damage via UV radiation, but the melanin producing pathway takes time (it takes at least four hours to see a tan and then 5-7 days of repeated sun exposure to get the full effect). The use of high pressure tanning devices was reported to be particularly dangerous, increasing the risk of melanoma to four times that of people who did not use tanning beds (3).
Last month, Polizzi even slammed president Obama for imposing a new 10% tax on tanning beds that went into effect on July 1st.
Pheomelanin is a yellow-red pigment present in abundance in people with red hair and fair complexions. Overall, the amount of exposure is thought to be the greatest risk factor for development of cancer and the cumulative number of tanning hours logged was a significant predictor of cancer development risk.
Republican political opponent, John McCain, was quick to respond to Snooki’s criticism of Obama with a tweet supporting Polizzi’s “freedom to tan,” a fairly controversial move considering McCain’s recent struggle with the deadly skin cancer, malignant melanoma. Some individuals are unable to produce melanin at all due to gene defects or enzyme deficiencies that they are born with. Basically, while you spend time building up your base tan you are concurrently building up mutations in your DNA, predisposing yourself to skin cancer. This study is the largest ever to examine the use of indoor tanning as a risk factor for melanoma.
Naturally, with tanning now in the political hot seat (both literally and figuratively), we at House Call think it’s only appropriate to re-educate our readers on the process of tanning and the dangers of skin caner with scientific research and medical literature leading the debate (instead of reality TV stars and politicians).
These defects result in very light colored skin, hair and eyes (a condition known as albinism).
