The Importance Of Our O-zone Layer - 1,277 words
The ozone layer is one of the oldest things on the planet, older than any of the ancient creatures we see in our museums today. The ozone layer has provided protection for the living components under it for millions of years, and without the ozone layer, we most likely would not be here today. Our evolution would have been cut off millions of years ago without our planets ability to provide protection from the ever-harmful rays from our sun. Each year since the late 1970s much of the protective layer of stratospheric ozone above Antarctica has disappeared during September, creating what is commonly known as the ozone hole. The Antarctic hole now measures about 9 million square miles, nearly ...

Wireless Transaction Protocol Layer - 468 words
Mobile cannot be confined; that goes against its very nature. It needs to be free to take any shape in order to find and empower users when and where they need it. But by virtue of its malleable nature, mobile is difficult to grasp and as a result, content providers - already cautious from scars garnered during the wild and wooly dotcom days - aren't so quick to chase what might seem like a PDA pipe dream. It doesn't help that Wi-Fi--the flighty young ingenue of mobile content delivery - garners all the headlines with deals between cell phone and coffee superpowers that promise fast connectivity and caffeine on every block. In reality, even consumers willing to wait ten minutes for the privi ...

Fetal Development - 1,355 words
Fetal development starts with the process of fertilization. It starts when the female ovulates producing an egg. This egg then travels into the fallopian tube where it waits to be fertilized. Once sperm enter the body they must travel up the uterus until they make their way up to the egg. Once at the egg the sperm try to get in. They sperm wiggle their tails until they make it in. Once it makes it in the egg will not any other sperm in. The sperm that made it then drops its tail. After about twenty hours inside the egg the sperm finds the nucleus of the egg and fuses with it. Now the egg has all the genetic material that it needs to make a new human being. It nows begins to move down into th ...

... ws the cross-bridge to detach and re-attach to another active site on an actin molecule. This contraction cycle is repeated as long as free calcium is available to bind the troponin and ATP is available to provide the energy. The signal to stop contraction is the absence of the nerve impulse at the neuromuscular junction. When this occurs, an energy requiring calcium pump located within the sarcoplasmic reticulum begins to move the calcium back into the sarcoplasmic reticulum. This removal of calcium from troponin causes tropomyosin to move back to cover the binding sites on the actin molecule and cross-bridge interaction ceases. It is possible for skeletal muscle to exert force without ...

Ice Age Extinctions Of The Megafauna - 1,630 words
... vironments than do smaller animals. Larger animals are safer from predators than small animals are, but it is also harder for them to sustain in trying conditions. Many of the larger animals such as mammoths and bison travel in herds, and that, along with their large size, protects them from predators. However, when the predator is Mother Nature, there is virtually no defense. For modern day elephants, drought is the biggest concern. It can take twenty percent of a herd every year, but the elephants continue to exist (Ward, 1997). It would have been harder though, for the mammoths and mastodons to survive a drought. Because of their size and weight, the Ice Age Proboscidea had longer ges ...

Successful Painting Arcrylics - 651 words
Ching Hao once said, "There are six essentials in painting. The first is called spirit; the second , rhythm; the third, thought; the fourth, scenery; the fifth, the brush; and the last is the ink." This brings us to the three main steps to a successful acrylic painting: planning, preparing, and painting, to include all six of the essential elements. The first step to painting with acrylics is planning. Deciding what to paint is the first step of planning for most. Sometimes inspiration comes from just wanting to paint and then deciding what to paint or seeing something first and then deciding to paint it. A small minority of artists simply pick up a brush and start painting without any plan ...

The Shephard - 915 words
Throughout time there has been at least one constant that I am aware of. That constant is art. One particular piece of art stands out and catches the eye. That piece of art is The Shepherdess and Her Flock constructed and perfected by Jean Francois Millet. When one makes a certain judgment on a piece of art, one must be precise and certain about that judgment. When observing Millet's piece I will take in to consideration three things to make my judgment: use of color, theme, and meaning. The Shepherdess and Her Flock catches the eye very quickly. The painting consists of a shepherdess tending to her sheep in some remote hills perhaps and most likely in Western Europe. The shepherdess herself ...

Maxfield Parrish - 868 words
Maxfield Parrish, born Frederick Parrish, was one of the greatest illustrators of his time, ranking among top artists Van Gogh and Paul Czanne. From his day of birth July 25th 1870 in Philadelphia, to the day he died in 1966 at the age of 95 in Cornish, Parrish lived a full wealthy life without many disappointments or sorrows in what was called the Golden Age of Illustration. Parrishs works will be forever remembered as enchanting realistic paintings of fantasy and romance that hung in the homes of 1 out of 4 Americans in the 1920s. Many factors contribute to this artists success. One of the most important factors was his use of Dynamic Symmetry, a design theory based on geometric harmony an ...

Throughout the myriad of cultures on our planet, we find different and sometimes opposing beliefs defining the values of an ideal citizen. Among these beliefs it is difficult to isolate a single set and deem them to be superior to another. The reason for this is that they vary based on cultural tradition, religious beliefs and even the technological advancement of that particular society. Although it is more evident with multicultural belief differences, we find large contrasts within the gap of one generation in a single culture. This phenomena is exemplified in Alice Munros Friend of My Youth with the relationship between the narrator and her mother. The purpose of this paper is to examine ...

Strategic Management Of Quaker Oats Company - 1,731 words
The Quaker Oats Company, officially formed in 1901, is currently undergoing massive reorganization, which will dramatically change its position in the industry.

Last time our consulting firm found several major points of question and recommended solutions. Some of these recommendations were implemented with excellent success. The first and most arduous problem we examined was of expansion. Our recommendations for expansion were put into effect with several projects in various stages. In the past several months, the company has announced plans to build a structural mill next to its flat-rolled plant in Berkeley County, South Carolina; a mill for pickling and oiling, cold rolling and galvanizing hot-rolled coils in Hickman, Arkansas, and plate mill in Hertford County, North Carolina.

As we are approaching the 21st century communications is becoming a vital key in business and home computing. As a result we are constantly inventing new ways in order to make communications easier for the user to access in our daily lives. Therefore the information superhighway has sparred awareness in home technology or lack of home technology. The abbreviation MP3 stands for MPEG (Moving Picture Experts Group) layer 3, which is a standard format for storing compressed music. An MP3 file is an audio file that has been compressed (anywhere from 1/5th to 1/17th of its original size) without any noticeable loss in sound quality. That means a great sounding file, in a package small enough that ...

Do your homework and trouble-shooting before calling the printer manufacturer and blaming them for having a crappy printer. I will give you an example of what I am talking about. I was dealing with a PC support person for the Cleveland Cavaliers. I got an email stating that the printer has never worked since the day that they got it and has cost them thousands of dollars in down-time and he wanted to know what we planned on doing about it. I asked him what the problem was and he said, "It doesn't print jobs sometimes". Well, that is certainly helpful ...

Two years ago, MP3 was just another audio compression format. Today, it's a Net phenomenon that's at the center of an enormous controversy. That's because MP3 makes it possible for people with an Internet connection to bypass record stores (and cashiers) and download CD-quality music by their favorite artists--for free. MP3 is great for music lovers and cheapskates, who can download funky tunes to their hearts' content without spending a dime; however, it's a nightmare for musicians and record companies, who can only watch helplessly as their profits drop into a digital black hole. MP3 is short for MPEG-1 Layer 3 (Moving Pictures Expert Group), a format for storing digital audio. It uses an ...

Buying A Computer - 1,846 words
Buying a Computer today is much more complicated then it was ten years ago. The choices we have are abundant, and the information we must gather to make those choices is much greater. The average consumer is a more educated buyer; they at least have some ideas of what they want in a computer. Yet, we must still ask ourselves these significant questions; such as: What will the primary function of my computer be? What computer components should I consider at the time of purchase? How much money do I have to spend? Where should I go to purchase my computer? For this report, I will consider the requirements of a typical family: using a mini-tower PC with the Windows 95 operating system, word pro ...
