Mesothelioma, Lung Cancer, Asbestos Exposure and Other Tragedies You May Ignore (Reading About)
Lung Cancer, like all forms of cancer, is a terrible disease. It leaves its victims in so much pain and throws away their quality of life. It is caused through a variety of ways, the most popular one being tobacco smoking. Not surprising, considering the vast amount of people across the world who smoke. Less commonly known causes include exposure to petroleum gases you tend to inhale when at a filling station, exposure to asbestos and consistent exposure and/or inhalation of smog like that of being trapped in a gridlock rush hour.
A very rare form of lung tumors is mesothelioma. It affects a handful of people, for example in the United States, but its incidence rate is significantly growing, i.e. a lot more people than previously are being diagnosed with the malignant tumor. The cancer to a large degree can be caused by unprotected & prolonged exposure to asbestos. An outrageously high amount of the brave HERO rescue workers who endangered their lives to fight the madness of 9-11 as it unfolded in New York, developed mesothelioma and other (somewhat) preventable types of lung cancer. A lot of the SAINT rescue workers, beloved by their families, friends communities and country, sadly already passed away in the near decade since the atrocity was cowardly committed by terrorists.
There is no known cure for it to date. It is a horrible monster befalls unassuming, everyday people and shatters entire families. Many families grieving the loss of their loved one(s) are left to pick up the pieces from the havoc wrecked by the nightmare. Since mesothelioma is so much of a rare disease, it's very difficult for those left behind to come to terms with the realities of it, i.e. why it had to happen; 'If it's so rare, why did it have to happen to me/us etc?' I have had the chilling experience of witnessing a lady interact with group members of a mesothelioma forum, first asking everybody to keep her uncle in their prayers as he's battling mesothelioma, then returning a few days after to announce that he had passed away. This was very disturbing, especially as I was amongst the people who sent her goodwill messages to console her when she first made the announcement.
Due to the fact that mesothelioma is more often than not developed through the exposure to asbestos, it can unfortunately present itself in a number of (potentially) hazardous situations, if proper care is not taken to observe and inspect the environment at home, school, work or many other places. In the United States, for example, there have been a growing number of incidents of official/authoritative negligence on part of school boards, employers, government ministries etc to ensure that respectively children, artisans, civil servants etc are protected from (potentially) dangerous exposure to asbestos by protective means or even denial access.
The Mesothelioma & Asbestos Awareness Center reported "Those who've studied the potential hazard of asbestos caused by the collapse of the World Trade Center estimate that more than 110,000 people may have suffered serious exposure including 80,000 tower workers, 30,000 local residents, and 4,000 first responders. Deborah Reeve was the first 9/11 emergency responder to die of mesothelioma. Doctors agree that her exposure to asbestos was a result of her days spent working at the recovery site."
By and large, many organisations and institutions tend to flout regulations and health & safety procedures stipulated by law or stick to them in a completely unacceptable manner. Thereby, people are put at risk of contracting the disease and/or those who have already been diagnosed with mesothelioma are left uncared for, unattended by institutions and unable to get the professional and highly competent support and assistance they require, in a legal capacity.
The track record of legal experts in the fields of lung cancer and mesothelioma has been impressive; incredible amounts of compensation have been paid out to families of mesothelioma sufferers, in support of their plight to fight the cancer and address the gross maltreatment and inequality they have experienced at the hands of their academic or vocational superiors. It is therefore advised to quickly seek the help of a trusted legal expert, with a proven track record on lung cancer and mesothelioma litigation cases to best address the legal needs in the way it is deserved to have it treated.
Under no circumstances does this article intend in any way to discredit the United States of America. The content has been attempted to be portrayed as factually as possible. Any subliminal mocking of any nature that could possibly be inferred from it, is completely unintentional.

creating a PCB for a circuit?
Hi, I need to buy some things to make a PCB. I was wondering if there is a US supplier that sells the following products:
PHOTO RESIST (in spray form)
PHOTORESIST DEVELOPER (in spray form)
SMALL UV EXPOSURE UNIT
UV LIGHT TUBES
Can you please provide a link to the sites?
Thank you very much!
There used to be a company named Kepro that sold bare boards, pre-sensitized bare boards, and chemicals necessary for developing the photoresist and etching the copper from the boards. Kepro sold through distributers such as Allied Electronics, Newark, Jameco, etc. They have long since disappeared as Kepro but have resurfaced as D&L Products or Dalpro in St, Louis MO. Kepro was also in St. Louis back in the 1960s time frame, so this may be the same people doing business under a different name.
We always bought boards with negative photoresist already applied. These were exposed using a #3 photoflood mounted in a forced-air cooled "light box" about six to ten inches away from the board. The boards were then developed in trichlorethylene, which is toxic and is know to cause cancer in California bred mice. One of our lab workers was sensitive to the stuff: his skin developed bleeding cracks from developing the boards without protective gloves. Or so he claimed. It never seemed to bother me, except it did remove all the oils from my skin.
The outside of the light box was just cheap particle board. The inside of the light box had mirror-finished sheet aluminum sides (you can buy this stuff from McMaster-Carr) to help collect the light from the photoflood. A simple sliding frame held a sandwich consisting of a foam rubber base, the sensitized board, the circuit negative, and a glass cover plate. I don't remember where we acquired it, but it wasn't very expensive, even with a squirrel-cage blower and mechanical timer for the light. Exposure time was on the order of five or ten minutes as I recall. An shortwave ultraviolet lamp would probably allow for shorter exposure times as the UV output of a #3 photoflood isn't all that much. Most of the energy goes into making heat, not UV, but it works. We still use it here in my lab, almost 40 years later, to expose silicon wafers coated with a spin-on positive photoresist.
Back in the day, we used to tape-up our artwork using Bishop Graphics mechanicals and then make a negative contact print using Kodak Kodalith film developed with A and B developer made up as needed. The developer only had a shelf life of a few hours after mixing. Needless to say, everything was 1:1 scaling with this approach.
Today you can use inexpensive circuit board layout software to create Gerber files and/or PDF drawings to print on a Laser Printer. You can even buy special Transfer Paper that will transfer a laser toner copy of your artwork directly to the blank copper using an ordinary iron (like for clothing). The board can then be etched using the transfered toner as the resist. My son used to make boards this way at Ohio State University when he was a studen there, but I've never tried it. You can also get boards made commercially using the vendor's free layout software at a cost that averages out around $100 per board in onesie-twosie quantities.
A small UV exposure unit may be adequate for exposing photoresist, but we purchased ours to erase EPROMs. No one uses EPROMs much anymore since Flash RAM is readily available, inexpensive, and relatively easy to program, erase, and re-program for hundreds or even thousands of cycles. As I recall, that simple little shortwave UV EPROM eraser cost upwards of $200. Avoid that if you can.
