Mobile phones and WiFi radiation health risks

There have been many skeptics since the very initial introduction of wireless service about what the constant exposure to radiation can do to human health and the nature surrounding it.

While the world is bracing for the launch of 5G services the question of the health risks looms large.

The result of the extensive study that was conducted by the National Institutes of Health, US was inconclusive. The 10 year study was conducted using 2G and 3G wireless radiation exposure on animals for 9 hours each day. While it did show the increased risk of mutation leading to the growth of tumors or tissue and DNA damage in a group of rodents, another group did not show any evident health issues related to the exposure.

The International Agency for Research on Cancer has cited exposure to radiation as a potent carcinogen for humans. It means that long term exposure to radiations could result in extensive damage.

But here is something to think about. The studies were conducted on animals that were expo…

Computers Through The Ages

Steve Jobs and Bill Gates are both names that are synonymous with computers. Well, at least they are with modern computers but they were just building on an idea that came along in the 1800's and continued to grow throughout time. What used to be huge machines that took up all sorts of room and did only rudimentary (to our standards) work, we now hold in our hands and of course technology is only advancing further all the time.

So, we go back in time, to an Englishman named Charles Babbage who, most say was born just too early for his ideas. He originated the concept of a programmable computer and because of this is known as the father of the technology. He invented the first mechanical computer back in 1833 which was an analytical engine. The input of data and programs was to be provided to the machine through punched cards. The output had a printer, a curve plotter and a bell and it could punch numbers on cards that could be read at a later date. His idea even had an arithmetic logic unit, control flow and integrated memory, which would have been, had it been made, the first ever design for general use.

All of the parts for Babbage's machine had to be made by hand and unfortunately his idea never reached fruition as the government cut his grants and he ran out of money. His son, Henry Babbage did make a simplified version of his dad's idea though, in 1888 and he successfully demonstrated that it worked in 1906.

All of these ideas made way for the analog computers which used direct mechanical or electrical models of a problem as the basis for the computation. But, they were not programmable, they weren't accurate and they weren't very versatile. Something had to change.

The first programmable electronic computer was ENIAC which was fast and flexible and was completed in 1946. The program was designed by the states of its patch cables and switches. Someone would write a program and then mechanically set it into the machine with a manual reset of the patch cables and wires. It was a far cry from what we have today in the way of computers as it took up 1,800 square feet and weighed a hefty 50 tons. Imagine hauling that around in your pocket!

Technology kept progressing and today we can do almost anything from a tiny device we carry around with us. Incredible. What is next? Stay tuned!

History of Printing

The background of printing goes back to the duplication of photos through stamps in extremely early times. Making use of round seals for rolling an impression into clay tablet computers returns to early Mesopotamian world prior to 3000 BCE, where they are the most typical masterpieces to endure, and attribute facility as well as attractive photos. In both China as well as Egypt, the use of tiny stamps for seals preceded making use of larger blocks. In China, India and also Europe, the printing of cloth certainly came before the printing of paper or papyrus. The procedure is basically the exact same - in Europe unique presentation perceptions of prints were usually published on silk till the seventeenth century. The development of printing has actually made it feasible for publications, newspapers, magazines, and also other reading materials to be produced in great numbers, and also it plays an important role in advertising literacy among the masses.

Block printing is a strategy for pri…

How Does The Flu Shot Work?

Medical experts recommend that everybody should get a flu shot before the peak flu season begins, which is from December to March. However, many people simply prefer not to take it because of the mistaken notion that taking the vaccine will actually give them the flu. There is a reason why people believe this.
It is a known fact that vaccines actually contain the virus that they are made to kill. This means, in the case of the flu vaccine, it actually contains the flu virus. This naturally triggers the question - won't it then cause the symptoms in the person who gets the shot?

To understand how this works, take a look at how vaccines work.

How flu shots work

The influenza virus is first deactivated and then used to prepare the vaccine. About ten to fourteen days after you've received the flu shot, the deactivated viruses help to develop antibodies in your body. These new antibodies are strong and robust enough to prevent any new influenza viruses from invading th…

Harmonization and Labeling

• This article is not to be confused with the Global Harmonized System of Classification and Labeling of Chemicals (GHS) standards, also called CLP in the EU whose main purpose is to communicate hazards on product labels and safety data sheets.

• In general the principals of harmonization are the same, i.e. to 'make one' or create a common framework, whether it be for labeling or for other purposes. Harmonization brings Clarity, Consistency, Confidence and Compliance. Imagine if all countries follow the same regulatory labeling guideline, the savings in cost would be significant. It was with this same intent that CODEX was established by the WHO way back in 1963 with the intent of developing food standards, codes of practice, guidelines and other recommendations which can be adopted by all member countries. Even though CODEX is still active, Codex standards and related texts are voluntary and member countries are not bound by or required to adopt them. Many coun…

She had spent half the night thinking about her plan to tell Gina—the “former friend” who had stolen her boyfriend, Jimmy—that she had seen Jimmy and Susan Brock at the movies. She didn’t plan to mention that Jimmy had been at the theater with a couple of his friends and Susan had been standing in line behind Jimmy with her parents.She had spent hours wrestling with the rightness and wrongness of her decision but had fallen asleep determined to get even with Gina.I’ve made my decision, she told herself as she got dressed.

Safety of Fertility Drugs

By Sunita Verma Safety of fertility drugs - Is it a cause of concern?For millions of women struggling to conceive, fertility drugs are the first stepin treatment. Clomiphene works by stimulating the hormones in brain that trigger an egg (or several) to develop and be released from ovaries. Gonadotropins stimulate ovaries directly to produce eggs. Women typically produce only one or two eggs a month. Human menopausal gonadotropin (hMG), urofollitropin, or recombinant FSH prompts the ovaries to produce several eggs. One of these drugs is injected into the muscle or under the skin. What are the risks of gonadotropin treatment?• Conceiving multiples is the most common complication of gonadotropin treatment. Of these pregnancies, two-thirds are twins and one-third are triplets. • Though many couples consider this a blessing, carrying multiples increases risk of miscarriage and other complications. • During stimulation for natural conception or IUI if three or more follicles are growing to…

Business Negotiation - How Do You Know When To Trust The Truth - Negotiation Tip of the Week

By Greg Williams"You don't know what the truth looks like, even though I've recited it numerous times to you through my ever-changing story."What does the truth feel like, sound like, look like, when you feel it, hear it, see it?

Then, as greater insight, discoveries, and other machinations are introduced into our environment, a new truth can emerge.It's important to understand how you discern what you perceive to be the truth because others can manipulate you, based on what they know of your ability to distinguish between fact from fiction.To become more cognizant as to when someone might be engaging in the truth, versus having no relationship with it at all, take note of the following insights.Demeanor - Yours and Theirs:Always note the demeanor of someone when they engage wi…
