| May 27th, 2008 | Introduction To Radiation Detectors |
Since we cannot see, smell or taste radiation, we are dependent on instruments to indicate the presence of ionizing radiation. Radiation is energy traveling in the form of particles or waves in bundles of energy called photons. Some everyday examples are microwaves used to cook food, radio waves for radio and television, light, and x-rays used in medicine. Radioactivity is a natural and spontaneous process by which the unstable atoms of an element emit or radiate excess energy in the form of particles or waves. These emissions are collectively called ionizing radiations. Depending on how the nucleus loses this excess energy either a lower energy atom of the same form will result, or a completely different nucleus and atom can be formed. Ionization is a particular characteristic of the radiation produced when radioactive elements decay. These radiations are of such high energy that when they interact with materials, they can remove electrons from the atoms in the material. This effect is the reason why ionizing radiation is hazardous to health, and provides the means by which radiation can be detected. How Does a Radiation Detector Work? SCINTILLATION DETECTOR: The basic principle behind this instrument is the use of a special material which glows or “scintillates” when radiation interacts with it. The most common type of material is a type of salt called sodium-iodide. The light produced from the scintillation process is reflected through a clear window where it interacts with device called a photomultiplier tube. The first part of the photomultiplier tube is made of another special material called a photocathode. The photocathode produces electrons when light strikes its surface. These electrons are then pulled towards a series of plates called dynodes through the application of a positive high voltage. When electrons from the photocathode hit the first dynode, several electrons are produced for each initial electron hitting its surface. This “bunch” of electrons is then pulled towards the next dynode, where more electron “multiplication” occurs. The sequence continues until the last dynode is reached, where the electron pulse is now millions of times larger then it was at the beginning of the tube. At this point the electrons are collected by an anode at the end of the tube forming an electronic pulse. The pulse is then detected and displayed by the instrument. GAS FILLED DETECTOR: This instrument works on the principle that as radiation passes through air or a specific gas, ionization of the molecules in the air occur. When a high voltage is placed between two areas of the gas filled space, the positive ions will be attracted to the negative side of the detector (the cathode) and the free electrons will travel to the positive side (the anode). These charges are collected by the anode and cathode which then form a very small current in the wires going to the detector. By placing a very sensitive current measuring device between the wires from the cathode and anode, the small current is measured and displayed as a signal. The more radiation which enters the chamber, the more current is displayed by the instrument. Many types of gas-filled detectors exist, but the two most common are the ion chamber used for measuring large amounts of radiation and the Geiger-Muller or GM detector used to measure very small amounts of radiation.

An idea was assumed to do a food book which would be filled with primary London eateries including Polish restaurants plus a range of price tags. The restaurant guide would be in the shape of a small pocket book that would make it easy to carry all over with you. What makes the guides so particular & diverse from any other eating guide is the fact that they are enjoyed by everyday folks, not practiced restaurant reviewers. After the success of the food guide, later followed the victory of the site, The website itself can tell you just about everything you need to know about pretty much each and every Irish restaurants in London, it’s uncomplicated to navigate around and has a lovely search region where you just have to put in the name of the Burmese restaurants & what county it is in and it will find it for you.

| May 24th, 2008 | Burning Fat While Keeping Your Muscle |
Most people who diet have a goal to lose pounds, inches and fat. The problem is, most approaches only focus on the actual amount of weight loss and not the maintenance of existing muscle tissue. The problem with this? Well, the fundamental problem with this common approach is that muscle can be compared to a fat burning machine metaphorically speaking. Without muscle mass, it would take all of us five times longer to burn off the stored up fat that gives us puffy bellies, love handles and thunder thighs. Any personal trainer or nutritionist will tell you that retaining muscle mass while losing weight is critical not only to your long term success, but also to the shape and look of your body. Muscle tone and mass is what gives us those coveted curves, ripples (the good kind), and definition. People with more muscle tone simply look much thinner, healthier and more defined. So, how can you assure you remain a fat burning machine while retaining muscle? 1. Up your cardio rather than your strength training if you’re pressed for workout time. Cardio both burns fat and sculpts and tones muscle. Putting cardio before strength and weight training in the beginning stages of weight loss is critical to both fast fat reduction and muscle maintenance. After the initial few weeks, you can again increase your strength training. 2. Opt for a diet that favors lean protein over fatty proteins (like the Atkins diet, which doesn’t favor lean over fatty). Also opt for whole grains and whole wheat, which will not promote water weight and puffiness like white refined and bleached flour products will. This should also be consumed in moderation though. You’re going to have to forego the sugar too. Sugar leads to excess water retention and fat storage. It essentially keeps fat from being properly metabolized and burned by the body, since the sugar is burned off first. You may also want to avoid excessive sodium. Bodybuilders actually use this trick to help their muscles look more defined, since the layer of water-retaining tissue that normally may be there over the muscle gets thinner and exposes more ripples and definition. 3. Protein shakes. Some, not all, protein shakes can help to retain your muscle mass. These are usually high protein, low fat shakes that are made with whey or other lean protein powders and skim or soy milk. 4. Keep your metabolism revved up. If you have a desk job, get up and go into a bathroom stall if you have to for a round of twenty squats. Do this as often as you can. It’s a great calorie burner and fat blaster. It also boosts your energy and helps sculpt buns and thighs. Visit Fat Loss Supplement for more information on effective fat blasting supplements and methods.

| May 24th, 2008 | Mortgage Loan Interest Rate Basics |
Understanding interest rates is an important part of finding the right mortgage for your home. Making informed financial decisions requires doing your homework; here are the basics of mortgage interest rates. Mortgage interest rates come in two flavors: fixed rates and variable rates. Fixed interest rate mortgages do not change their interest rate for the duration of the loan. Adjustable rate mortgages change at regular intervals. Both types of interest rates have their pros and cons. Fixed Rate Mortgages The main advantage of a fixed rate mortgage is simply that this interest rate does not change. Homeowners with fixed interest rate mortgages have the peace of mind in knowing that their monthly payments will not change when interest rates go up. The disadvantage of a fixed rate loan is that these mortgages come with higher interest rates; you will pay a premium for this peace of mind. Adjustable Rate Mortgages Adjustable rate mortgages have the advantage of lower rates and monthly payments, at least initially. These loans typically come with an introductory period where the interest rate is very low; at the end of the introductory period the lender will adjust the interest rate to the current interest rate, plus their own markup. Adjustable interest rates are typically lower than fixed interest rate loans; however, when interest rates go up and the lender adjusts your mortgage you could see the monthly payments go up significantly. Adjustable rate mortgages are much riskier for the borrower than fixed rate mortgages.

| May 23rd, 2008 | Falling Down is a Fear of Many Seniors - It Might Not Need to Be |
We can define proprioception (I know, it took me a few tries to get it right) as a person’s perception of stimuli relating to his or her own position, posture, equilibrium, or internal condition. Proprioception came heavily into play for me at least twice in the last four weeks. Once on a cold, rainy day in Illinois I had to step in a puddle as I was walking through a parking lot. As luck would have it, the pavement was broken and uneven at the exact spot where my foot fell, and I tumbled forward. A few days later, as I was descending a set of external stairs in the dark in Connecticut, my foot landed on the next to last step. It came down near the edge, and part of the edge had worn away. Again I tumbled forward. Now, as they say, the rest of the story. I am 60 years old. By all rights, at my age, I possibly should have hit the ground and broken a bone or two. What actually happened in Illinois was that I whipped my other leg forward, caught my balance, and kept on going. In Connecticut, I pushed off the stair with the ball of my foot, swung my other leg forward and jumped to the ground…and kept on going. Actually, we all deal with proprioception several times a dwy. Every time we take a step, we fall forward, and proprioceptive awareness tells us at each moment of the movement where we are and what we need to do about it. However, as we age, this awareness process begins to fail for various reasons, and this is one of the reasons older people tend to fall more often. Add to this the fact that bones begin to thin out and become more brittle and…Presto! Change-o! Life suddenly becomes a lot more challenging at best and downright dangerous at worst. In fact, to make matters worse, as we become consciously or unconsciously more aware of this change, we tend to alter our lifestyles in ways that cause us to lose even more of this faculty. The very act of protecting ourselves from the presumed pitfalls of old age causes us go get out less and do less, and this lack of physical activity contributes to the deterioration. As we become more uncertain of our ability to navigate and function or become more fearful of damage to ourselves, we tend to “hole up” within our homes, and, more sadly, within ourselves. To digress for just a moment, as I am prone to do, I used to be the Business Manager for a county mental health facility in Florida. I have always been interested in geriatrics as I felt, and seemed to be learning, that many people suffer affects of ageing to a much greater degree than necessary and condemn themselves to the very conditions they fear. My frequent conversations with Diane, the head of our geriatric program, tended to confirm this. On more than one occasion, she looked sadly around the room at people unaware of their location or the date and time or unable to take part in the program’s activities, and tell me, “Most of these people should never have wound up here! They could have done things to prevent this from happening to them.” Over the years, I have come to agree with her…both from what I have learned, and from what I personally have experienced. Without going into a lecture on anatomy and physiology, as we age, various components within the muscles of the body which constantly send data to the brain gradually begin to shut down or withdraw. Additionally, tissue which connects the muscles to the bone begins to thin out, lose flexibility, and also reduce the depth and condition of their links to the bone. The simple solution to this is regular motion and load-bearing, or resistance exercises. Not only do these types of exercise strenghthen the muscles (like what I needed in my jump), and encase and protect joints (like my knees when I hit the ground), they help reestablish the faculty of proprioception. First, the system itself gets a workout that helps keep it up to speed, repairing and rejuvenating the various transmitters that keep the brain informed. Second, the muscles dig their connectors into the bone to a greater depth, protect the joint more effectively, assist the bone in becoming less brittle and more substantial, provide power for sudden movements, and also aid in providing the brain with more data, so it can figure out where every part of the body is, and what to do about it. By the way, exercises or exercise machines that require the body to stabilize itself, for example free weights as opposed to a static exercise machine, are much more effective in producing positive affects in this area. As you have long suspected, a fit senior citizen (or young whipper-snapper, for that matter will be better able to enjoy life at any age, be less prone to injury, and will probably simply last longer than the unimproved model. Yes, I do resistance exercises several times a week in addition to regular aerobic activities, and that is why I was able to come through both of those events I mentioned above, AND let my six-year-old granddaughter crawl all over me and engage in roughhouse play with her and the dog without any ill affects.

| May 22nd, 2008 | Tips for Ordering Online |
Make sure you know who you are Let’s switch roles. You are now the customer and you want to buy something. You know that the items you buy will be shipped to you and arrive in a few days, so there is no instant gratification involved when ordering over the net. Take a look at how easy it is to navigate around your site and how easy is it to get to the place where you can purchase the items. If you find it difficult to get to the online store, make note of it and make some changes. The easier it is to find the items, the easier it is to buy from you. I am working with a customer that has a great looking web site but the navigation and scrolling to purchase is extremely difficult. Some of the links do not work and you cannot get back to the home page. If they made it easier (and we have given them a proposal on how to do that), they would likely increase their sales. Besides ease of use, you also need to look at the security of the site when doing the purchasing. I would never give my credit card to a site that does not have a secure server to process the payments. You can tell if it is secure by the lock that is closed at the bottom-right of the screen. If the lock does not appear, I go elsewhere to purchase. One more thing to be aware of is the follow-up you do after the purchase is made. Most online stores such as Amazon send an email to confirm your purchase. This gives the customer an opportunity to change their mind or refute the purchase. Amazon also sends an email to say that the item has been shipped and when I can expect it at my front door. Take care and make it easy for your customers. They want to know how much their purchases cost, when the package is to be expected, what additional costs will be incurred by the shipping method chosen and the total cost of the transaction. They expect you to follow up the order to make sure that they get what they expect and that the goods they ordered are received in good condition.
