    IBM PC
    August 12, 1981 - United States

    IBM introduced the PC personal computer for $1,600 base price. It shortly eliminated most other machines suitable for home or small business such as those with the S-100 bus, running on CP/M or their own operating system. The PC was developed in less than a year at IBM's Boca Raton Florida facility by using existing off-the-shelf components. The IBM-PC established the dominance of the Microsoft operating system. The IBM PC hardware design also became the industry standard for PC compatibles, with the ISA bus. Its Intel 8080 processor speed was 4.77 MHz, and it used from 16K up to 640K of memory. Data storage choices included 5.25" floppy drives, cassette tape, and later hard disks.

    The continued debate over the use of therapeutic cloning for stem cell research continues to gather pace both in America and other countries of the world . Many believe that the research will lead to medical breakthroughs in Multiple Sclerosis, Parkinson's and Alzheimer's disease. Many believe that the research raises serious questions of 'ethics' and embryos have rights to life which is a gift from God not from a scientist in a lab.

ARTICLE INFORMATION :

For a long time, the use of artificial grass and synthetic turf has been limited to sports stadiums. However, its reach is now extending to home compounds as well. It definitely has its merits as well as demerits.

ARTICLE CONTENT :

By analyzing these ones in relation to those of natural grass can help one make a sound decision about its use.

1. Artificial grass makes it possible to realize a great deal of savings in several ways.

• First, the amount of money invested in laying it out as compared with its durability is reasonable. While making a natural turf is rather inexpensive, its maintenance costs in the end make it more costly than this one.

• Second, the energy efficiency that comes with it cuts back costs significantly. This is notable when one considers the amount of fuel used annually by a simple lawn mower. Time that would be used in carrying out maintenance practices is also saved, making it convenient for the sick or elderly to manage their backyard easily.

• The modern day urban neighborhood has to cut down on water spending and this proves damaging to natural landscapes. Since artificial grass and synthetic turf does not need watering, makes it useful in these areas.

• Replacement costs in high wear and tear regions are avoided with this type of grass. These are areas where children play, dog runs and even around the swimming pool where splashing water can damage a natural lawn. Sporting arenas also enjoy its benefits.

2. Artificial grass and synthetic turf is also an environmentally friendly option.

• First, it needs no pesticides and thus prevents the negative effects of runoff from chemical treated yards.

• The fact that it needs no mowing means a significant reduction of carbon emission into the atmosphere.

• Clippings from cut grass have also been associated with environmental pollution in several ways. Hydrocarbons are released into the atmosphere; the clippings clog drainage pipes and finally end up in rivers and pollute them.

Another benefit associated with this type of grass is the fact that it gives your yard eye appeal all year round. Seasonal changes do not affect this grass and as such, it will never fade to a dull brown.

Nevertheless, artificial grass and synthetic turf has a number of significant disadvantages. First, the production of the grass involves a lot of carbon release into the atmosphere. This cuts down greatly on its environmental friendliness. The process also involves high energy consumption.

Furthermore, even though the grass is highly durable, after a while it needs replacing. The old grass goes to polluting the environment if not well disposed of.

Natural grass though, rids the environment of harmful Carbon Dioxide by absorbing it. It also breaks down pathogens and is thus a suitable option for playground since it has a lower chance of getting them sick. Wastes decompose with time and pose no risk to the environment.

Weighing these factors and assessing the particular needs of an area can help one in choosing correctly between natural grass and artificial grass and synthetic turf.

Artificial grass or synthetic turf is great for home garden. By installing fake grass, home owner can also save money on water bills.
