Internet security 2
Internet security 2 Internet Security As we head into the next millennium many people are beginning to question the computer systems that so many of us depend on. This is not the first time that people have become scared at the end of a century, let alone a millennium. People have always had on thing or another to be worried about at these turning points in time. When people first heard of the Y2K problem they began to realize just how big of a problem security is on these systems. Not ...
Internet security
Internet security The Internet is the community of the future, but if security measures are not put in place and enforced, then it will become more of a slum and less of a community. The primary question is, therefore, who has the obligation to put these security measures into place? Is it the individual users of the computers and the Internet? Is it the responsibility of the companies that develop the different computer applications to place certain security measures in place? Or is it the ...
Insomnia
Insomnia Flowers fold their petals; plants fold their leaves as evening falls. With the exception of owls and their nighttime predators, the creatures of land, sea, and air curl up into their bedroom niches in the rocks, trees, and sand. Dawn comes and the unfolding begins. The outside world, which has been barred from the senses of the sleepers, is once again admitted. This rhythm is the most natural thing in the world, intended no doubt to be accomplished effortlessly. Yet, many people...
Intel vs
Intel vs. amd the true story (intel bias) The processor world used to be only Intel, now there is another contender, AMD (Advanced Micro Devices). A couple years ago when AMD first made its way into the scene there were many incompatibility problems with AMD processors and programs. However due to changes in the design these incompatibility problems no longer plague the AMD line of processors. But it is a known fact that an AMD equivalent of any Intel processor is about 30 to 50 MHz slowe...

Information about transgenic organisms
Information about transgenic organisms Transgenic Organism, plant, animal, or bacteria that has been genetically modified to contain a gene from a different species. The new gene is inherited by offspring in the same way as the organism's own genes. The transgenic condition is achieved by injecting the foreign gene into the fertilized egg or into embryonic cells. The injected gene becomes part of the host cell's deoxyribonucleic acid (DNA) within the chromosome and is then inherited by all t...

Information warfare
Information warfare As we entered the third wave, we traded in our pens and notebooks, for keyboards and CPU’s. A simple wire connected from a phoneline to a modem to your CPU, brings the whole world into your hands. And you into the worlds hand as well.

In vitro fertilization
In vitro fertilization In Vitro Fertilization (IVF) is a procedure that offers hope to couples who otherwise are unable to conceive. This process is important to infertile couples because it gives them another chance of conceiving a child. In order for normal pregnancy to occur, an egg is released from an ovary and unites with a sperm in a fallopian tube. However, during the process of IVF, this union occurs in a laboratory after both eggs and sperm have been collected. The fertilized eg...
Indicactor lab
Indicactor lab What is in each test-tube? What proof do I have of this? Test-tube A: Test-tube A had water in it. I can base this on the fact that it was a neutral, reacting neither to red or blue litmus paper. Phenolphthalein also did not react to this substance. The pH value was 7, neutral, also adding to the proof that this substance was water, because water is neutral. The substance was clear and odorless, and all of these reactions combined led me to my conclusion of substance A be...

Hypothermia
Hypothermia Hypothermia In this essay I am going to explain what hypothermia is. How can one be exposed to get hypothermia and who are the people who are most likely to get it when exposed to the cold. I am also going to discuss How to prevent hypothermia or death when caught in cold water. What the symptoms and consequences of it are and their treatments. How it can be used for medicinal purposes. Hypothermia is a condition in which body temperature falls drastically as a re...
Hysteria
Hysteria Hysteria is a very unique and abnormal mental disease. What makes it so interesting is that it causes physical symptoms that someone would not normally experience. “Mental conflicts are unconsciously converted to symptoms that appear to be physical, but for which no organic cause is found”(Hysteria 1). One major outburst of hysteria occurred in 1692, resulting in the deaths of twenty-four innocent lives. “By the time hysteria had spent itself, twenty-four peopl...
I
I.t. doctors database analysis There are some parts of a Doctor’s Surgery that could benefit from computerisation. As time goes on technology will aid most types of work, for instance office work (Department of Trade and Industry, for example). Technology could be used in a Doctor’s surgery to computerise the patients’ files, to print out prescriptions and certificates for things like immunisations. The patients’ file would consist of their name & address, telephone n...
Hydrogen 2
Hydrogen 2 Hydrogen in it's liquid form has been used in space vehicles for years. Hydrogen has a high combustion energy per pound relative to any other fuel, meaning hydrogen is more efficient on a weight basis than fuels currently used in air or ground transportation. Hydrogen is the universe's most abundant element. Most of that hydrogen though, is tied up in chemical bonds. Hydrogen can exist in either a gaseous form or a liquid form. Hydrogen is The liquid form is usually used for...
Hydrologic cycle
Hydrologic cycle HYDROLOGIC CYCLE The hydrologic cycle is a constant movement of water above, on, and below the earth's surface. It is a cycle that replenishes ground water supplies. It begins as water vaporizes into the atmosphere from vegetation, soil, lakes, rivers, snowfields and oceans-a process called evapotranspiration. As the water vapor rises it condenses to form clouds that return water to the land through precipitation: rain, snow, or hail. Precipitation falls on the earth and eit...
Hydroponics growing without soil
Hydroponics growing without soil Hydroponics: Growing Without Soil The science of growing plants without soil has been known and used for more than one-hundred years. The word “hydroponics”, however, is comparatively new. Dr. W.E. Gericke is usually given credit for coining the word, which translated from Greek, means “working water”. The famous hanging gardens of Babylon were probably on of the first attempts to grow plants hydroponically. The work of Dr. G...

Capable of changing a person’s behavior, modifying daily routines, causing odd reactions to normal things, plus countless other phenomena’s.

But, in this report, I will prove that on the stage, in the therapy office, and in the mass public, Hypnosis does exist and is capable of changing o...
Hypnosis
Hypnosis Hypnosis The common view of hypnosis is that it is an altered state of consciousness, a trance-like state characterized by intense concentration, extreme relaxation, and high suggestibility. Many who accept this view also believe that hypnosis is the way of accessing the unconscious mind, thereby allowing the recovery of repressed memories, multiple personalities, and even memories of past lives. Since at least the 1960's this view of hypnosis has been seen as a myth by scien...
Hurricanes 2
Hurricanes 2 Hurricanes Hurricanes get their start over the warm tropical waters of the North Atlantic Ocean near the equator. Most hurricanes appear in late summer or early fall, when sea temperatures are at their highest. The warm waters heats the air above it, and the updrafts of warm, moist air begin to rise. Day after day the fluffy cumuli form atop the updrafts. But the cloud tops rarely rise higher than about 6,000 feet. At that height in the tropics, there is usually a layer of...
