One of the oldest activities I can remember doing while on a camping trip is whittling wood with my knife. In fact, you pretty much can t go camping without the right tools - hammer to drive tent pegs, knife to cut, and so forth. Of all these tools, the camping knife is the most essential - and most useful of all. This is because it has so many uses, not only limited to cutting trees or branches, but for cooking, setting up the camping area as well as for protection. Best of all, the camping knife is most often a utility knife, so you can use it as a can opener, tweezers, scissors, and more. If you really want a good camping knife, go for a swiss army knife. These can get pretty expensive but there are ones for less than sixty dollars out there. If you intend to do lots of whittling or cutting, don t buy one of these knives as they are very hard to hold - get a hunting knife instead. You may also want to get a whetstone - a special sharpening stone for knives. If your blade is dull, you will spend way more effort to cut things. The blade should do the work for you. General Purposes A camping knife can be...

It is interesting to note that the aging dog like his master is also prone to prostatic enlargement, but unlike his master does not often develop retention of urine. However, due to the bulging upwards of the enlarged prostate the dog s rectum is compressed. This engenders a feeling of continuous fullness in the rectum and induces straining. The prostates of eunuchs are small and underdeveloped, and enlargement of the prostate is unknown. Benign prostatic hyperplasia BPH is one of the most common diseases to affect men beyond the middle age. The prevalence goes up with age, and thus the total number of patients is increasing as a result of aging population. A majority of these people suffer gradual progression of symptoms and the concomitant discomfort, and require either medical or surgical treatment. The growth and development of the prostate is under the influence of male hormone testosterone . Rather surprisingly, there is no close correlation between the size of the prostate and the extent of outflow obstruction. However, the larger the prostate, the greater is the risk of BPH complications such as...

It s an unfortunate fact of modern life. Even when we try to return to the wholesome goodness of whole read, real foods, something is lacking. Thanks to the various methods of modern farming and transport, even the whole foods we eat are lacking in vital nutrients. While nobody would suggest switching from a diet rich in fresh fruits and vegetables to a diet of canned fruits and veggies even with some modern farming methods depleting nutrients, fresh is best it s important to understand why your fresh produce might not be as fresh or as nutrient-dense as you think. There are a variety of factors present in the field that can affect the nutrient quality of your fresh produce. Over the years consumers have demanded prettier fruits and vegetables, so fruits in particular are often picked when still green and ripen on their way to market. This makes them prettier but also leads to a reduction in overall nutrient value. For example, Cartenoid in fruits increase as fruits are allowed to ripen naturally, on the vine or tree. There is a strong farmer reliance on chemical fertilizers and a relative loss of...

Fundamental to our wellbeing is food and rest. Both have evolved into complex sciences that are subject to serious study and frivolous and sometimes dangerous trends. Initially sleep would have been snatched; anything more than 15 or 20 minutes would have increased the likelihood of early man becoming prey to larger more powerful predators. In these circumstances soft ground or perhaps a broad tree branch would have sufficed for a quick rest. Even now when you are utterly exhausted you can sleep just about anywhere and in any position. With time we became more organized socially and technologically, with fire and weapons and larger groups we could settle and gradually leave the more nomadic lifestyle behind. Of course with security we could now group all those condensed periods of rest into a longer more conventional nights sleep. From that time to this we have searched for materials that will provide a barrier between us and the ground, something that is capable of changing any surface into a comfortable, safe and warm environment. Through time we have moved from straw beds to feather beds, springs to...

However, if the entire surface becomes covered in calcium carbonate and this calcium carbonate becomes hard, this will prevent the anode from protecting the tank any longer. This is known as passivation. If the anode has passivated, it will not look so by sight alone. To test for passivation, you must bend the anode rod by hand. At the bend, observe for small amounts of flaking. The anode should be replaced if more areas of the rod are exposed wire than sacrificial metal. It should also be replaced if the top or bottom of the rod has deteriorated, exposing six or more inches of exposed wire. An anode should also be replaced if the anode is less than half of the rod s 3 4 in. diameter size. If the anode has passivated, split through its length, or has become heavily pitted, it could also be time for replacement. When all the sacrificial metal has worn away, then the steel rod will begin to wear away. After the steel rod wears away, the only thing left will be the hex head or the hot water outlet nipple if it is a combination anode. At this point, the tank will begin to corrode. If the anode is found in...

Future electronics based on molecules will help create smaller and faster computers. This is the current research being conducted by chemists at the University of Liverpool, one of the UK s leading research institutes. For several years experts have been working to comprehend how to work with very small electronic equipment. In the up and coming field of Nano-science and nano-technologies it is essential for scientists to control the structure and bonding of molecules used in manufacturing small scale electronic components for products like computers. In Liverpool, scientists have created a pentacene, which is the union of a single gold atom and a single organic molecule. They succeeded in binding the atom to the pentacene and took images of rearrangements of the electrons contributing to the formation of the chemical bond. The scientists chose the pentacene because it is a special kind of molecule with specific qualities useful in molecular electronics. The gold atom is a metal atom that attracts an extra electron to create the pentacene. Liverpool s University Chemistry Professor, Mats Persson said...
