Type 2 Diabetes – Smoking Plus The Effect Of Secondhand Tobacco Smoke On Non-Smokers!

According to the Mayo Clinic in the United States, smoking tobacco increases the risk of Type 2 diabetes by raising blood sugar levels, resulting in increased insulin levels. That can lead to insulin resistance which increases the chance of developing both Type 2 diabetes and heart disease. Anyone who smokes more than 20 cigarettes a day nearly doubles their risk of developing Type 2, in comparison with non-smokers.

Non-smokers who spend time with smokers often get the same diseases that are common in smokers. A group of researchers in the Department of Epidemiologyy and Health Index, Center for Genome Science, Korean Centers for Disease Control and Prevention, Osong, Korea, and the Department of Preventive Medicine, Gachon University of Medicine and Science, Incheon, Korea set out to discover whether secondhand tobacco smoke in the environment could put non-smokers at a high risk for Type 2 diabetes. The results of their study will be published in the journal Annals of Epidemiology in January 2011.

Ten thousand and thirty-eight people from 40 to 69 years of age were included in the study. Among four thousand four hundred and forty-two volunteers who had never smoked and had not been diagnosed with diabetes at the beginning of the study:

  • 485 acquired Type 2 diabetes within the next six years
  • those exposed to secondhand smoke at home had more than a 40 per cent higher risk of developing Type 2 diabetes than had those who were not exposed
  • the volunteers exposed to secondhand cigarette smoke for over 4 hours per day at home and in the workplace, had almost twice the risk of developing Type 2 diabetes than those who were not exposed

From these results researchers concluded secondhand smoke in the environment was a significant risk factor for acquiring Type 2 diabetes.

When given the option, it’s always wise to choose the non-smoking section of a restaurant or other public place. If secondhand smoke is a problem in the workplace, attention to ventilation or a discrete request to have it made a non-smoking environment might be helpful.

If family members smoke, sometimes they can be persuaded to smoke outside, use electronic cigarettes, or, better yet, to stop smoking altogether.

The Mayo Clinic has several suggestions for quitting:

  • not trying to have “just one” cigarette is recommended because satisfying a craving does not stop at just one
  • identifying and avoiding triggers
  • chewing gum can help
  • reminding yourself of good reasons to quit
  • requesting help from friends or family members
  • using nicotine products designed to curb cravings
  • any sort of physical activity can help

Unfortunately the stats show that once smokers quit, it’s likely they will resume smoking. But don’t let this throw you if you are a smoker. Try to stay away from other smokers and don’t be embarrassed if you feel you need to say “no” to the offer of a cigarette.

Whatever your decision, you must always consider the risks. Start smoking or even stop smoking, you have to enjoy it and you have … Read More

Types of Mechanical Seals

You are responsible for fixing a machine and all the parts seem to be in working order. However, you find fluid everywhere around it. What could be causing this mess? Mechanical seals are part of the intricate design of machinery and their purpose is to keep air, fluid and other substances from leaking out. Here are a few types of seals.

Hydraulic Seals

These types of seals, such as high pressure hydraulic shaft seals, are used to keep fluid trapped in a hydraulic cylinder. Oil or water pushes a shaft forward through the part to make this cylinder work. The seal is vital since the cylinder will fail without it. Hydraulic seals work great under high pressure.

Bonded Seal

Bonded seals are used to make a screw or bolt tighten a little better. Also known as Dowty seal, it is comprised of a washer and a rubbery piece. The two of them are threaded around the bolt or screw and between them seals tight when applied.


This might not seem like a normal type of seal, but sealant is also used to keep fluid or air from escaping a machine. Instead of being in the shape of a rubber washer, sealant typically comes in an aerosol can. You spray it into the crevice or hole you wish to make leak proof and after a small amount of time it creates an airtight seal. This sort of seal is great if you want to close up a hard to reach place.

Pneumatic Seals

This seal performs best in high speed situations that require low pressure. Like hydraulic seals hold back fluid, pneumatic seals hold back air or gas. These parts have to last a long like with little lubrication and stay intact when being exposed to air. They are primarily found being used in a rotary or reciprocating motions.

Printing Power to the People

There was a time when printing was the sole domain of ink-stained wretches who carefully set pieces of metal, covered them with ink, and started the presses. More recently, individuals could have their own mini-presses, with metal meeting ink in a typewriter’s insides instead of a print shop. Today, though, computers allow people who don’t know a doctor blade from a deckle edge or a pica from an elite to produce a colorful printed product without too much more than the press of a button.

On the Dot

Of course, the first computer printers weren’t exactly producing a slick, stylish product. They were essentially automated typewriters, dutifully tapping out your computer-entered words. The cheapest and quickest ones made up letters from a series of dots, not necessarily in the smoothest and most readable way.

Laser Sharp

Laser printers got rid of the need for something to strike a piece of paper and instead made letters with toner, like a copy machine. The result was a much more professional-looking product, at least in form, if not in content. Pages could include photos, a variety of fonts, and decorative elements of all sorts. You just had to be careful when replacing that toner cartridge, or you’d know how those ink-stained wretches of old felt.

The Inkjet Set

Inkjet printers seem to have taken over for home and home office use these days, and in addition to having petite little cartridges that are easy to replace, they add color to the picture. With a huge array of templates available online and in word processing software, ordinary folk can print photographs, flyers, greeting cards, booklets, and pretty much whatever else they can imagine.

Of course, for those times in our lives when we want something particularly polished—wedding invitations, business cards, our first novel—we’ll still turn to professional printers. Short of that, just go to your computer and hit print.
