Toxic Toiletries...

Have you ever wondered what goes into bubble bath, shampoo and many others toiletries? Apart from aqua, (by which

they mean water) the next most prolific ingredient contain in most type of toiletries especially shampoo is sodium laureth

sulphate. Sodium Laureth Sulphate is a surfactant. That is a substance that can reduce the surface tension of a liquid and

thus allow it to foam or penetrate solids. It is also an industrial grade detergent, or degreaser. Like all detergents sodium

laureth sulphate attacks grease, thereby helping to clean the skin. However, the human skin is a complex organ and

contains glands which deliberately secrete grease or oil onto the skin to help keep it waterproof, supple and, to quote, "soft

and smooth." sodium laureth sulphate strips the natural oil from the skin leaving it rough and dry. That's not all sodium

laureth sulphate does. Sodium laureth sulphate is a powerful detergent, garages use it to clean engine oil from their floors,

it is also very corrosive.

In fact, sodium laureth sulphate is so harmful to the skin that it is used in medical laboratories to damage the skin before

healing agents can be tested! Sodium laureth sulphate can pass through skin into the body where they enter the blood

stream and build up in the internal organs - especially the brain and kidneys. It can cause eye irritation, permanent damage

to the eyes, especially in children, skin rashes, hair loss, flaking skin and mouth ulceration.

What to watch out for When selecting kinder cosmetics and toiletries, choose products which do not have any of the following ingredients.

DEA, MEA, TEA, Cause allergic reactions, irritate the eyes and dry the hair and skin. Can be carcinogenic,

especially to the kidneys and liver.

Petrolatum, also known as mineral oil jelly, liquid vaseline, paraffinum, liquidum and baby oil. Can cause

photosensitivity and strips the natural oils from the skin causing chapping and dryness, also premature ageing.

Prevents elimination of toxins, can cause acne and other disorders.

Sodium lauryl sulphate (SLS) Found in shampoos, hair conditioners, toothpaste, body washes. Strong detergent

which can cause eye irritation, permanent damage to the eyes, especially in children, skin rashes, hair loss, flaking

skin and mouth ulceration. When combined with other ingredients, can form nitrosamines, which are

carcinogenic. Easily penetrates the skin and can lodge itself in the heart, lungs, liver and brain

Methyl, propyl, butyl and ethyl paraben, used to extend a products shelf life and inhibit microbial growth.

Highly toxic. Can cause rashes and other allergic reactions.

Fragrance. Usually petroleum based. Can cause headaches, dizziness, rashes, respiratory problems vomiting,

skin irritation and multiple chemical sensitivity

Talc, found in baby powders, face powders and body powders as well as on some contraceptives such as condoms.

A known carcinogen. A major cause of ovarian cancer when used in the genital area. Can also lodge in the lungs,

causing respiratory disorders.

Alcohol, or isopropyl. A poisonous solvent and denaturant (altering the structure of other chemicals). Found in

hair colour rinses, body rubs, hand lotions, after shave lotions, fragrances. Can cause nausea, vomiting headaches,

flushing, depression. Also, dries skin and hair, creates cracks and fissures in the skin which encourage bacterial

growth.

Sir Isaac Newton Newton is one of the founders of physics. He was the first man to formulate a law about gravitation, the law we now call Newton's Law of Universal Gravitation. Until Albert Einstein was born, Newton's conclusions about the nature of gravity were the only tool that physicists had. In addition, this amazing scientist is responsible for the equations that we use involving rotation and centripetal force. Newton was born in 1642, and contributed much more than gravitational laws during the course of his life. Isaac Newton is also responsible for the idea of a light spectrum, and he determined the properties of white light.

Ampere :

An Ampere (A) is the unit of electric

current. It is the flow of one Coulomb of

charge per second. In formulas, current

in Amperes is given as the letter I. The

Ampere is named after the scientist by

that name, and is sometimes abbreviated

to "Amps."

Anion Ions with a negative charge

Interpretation of this formula shows us that the velocity required for orbit is equal to the square root of the distance from the object to the center of the Earth times the acceleration due to gravity at that distance. At the surface this would be (6.4 x 106 m * 9.8 m/s2)1/2, or (6.272 x 107)1/2, or approximately 7,920 m/s. This agrees with our previous number of 8 km/s. (Isn't great when somebody else does the math for you?) However, satellites don't orbit at the surface (they could though). Going back to our other formula for the force of gravity on an object from any height, we can go through the process of rewriting the formula again. This time I think I'll just tell you it:

v=(GM/R)1/2

So if we wanted to put a satellite in a circular orbit at 500 km above the surface, it would need a speed of ((6.67 x 10-11 * 6.0 x 1024)/(6900000))1/2, or (58 x 106)1/2, or 581/2 x 103, or:

7615.77 m/s As you can see, this number is considerably smaller. If you use a larger speed, you can get an elliptical orbit, but don't use too much. If you do, you just may escape from the Earth's gravitational pull.

Adapted from http://library.thinkquest.org/10401/astro.html

How Does That Satellite Stay in Orbit ???? (while I just fall to the ground)?

In order to understand how satellites stay in orbit, we need to first look at gravity. Everything that mass has a gravitational field. Right now, your computer's gravitational field is pulling on you, and your gravitational field is pulling on the computer. However, since gravity is a relatively weak force, unless you're an extremely large object like a planet, you can't feel this pull. We do however feel the pull of the Earth on us. Everytime you jump into the air, the Earth's gravitational field pull's you back down. If you use more force you can jump higher, but you always return to the Earth. The force that the Earth's gravity pulls a specific object with is expressed in the formula F=mg, where m is the mass of the object and g is the acceleration due to gravity (approximately 9.8 m/s at the Earth's surface). However, that is a specific case at the surface of the planet. The full formula is

F = mg = (GmM)/R2 where F is force, G is the universal gravitational constant (6.67 x 10-11 Nm2/kg2), m is the mass of an the small object, M is the mass of the planet, and R is the distance from the center of the planet to the object. At the Earth's surface, neglecting all friction, an object could be put into orbit. However the speed would have to be 8 km/s (5 mi/s or 18,000 mi/h). We discover this by combining two formulas. The object in orbit would have to have a centripetal force (F=mv2/r) that counter-balances the gravitational force (F = mg). The two have a common factor of "F" so we combine them as mg = mv2/r. The m's can then be divided out, giving us g = v2/r. Then we multiply both sides by "r", giving us gr = v2. Finally, by taking the square root of both sides, we get

v = (gr)1/2

Amplitude :

In any wave motion, the maximum

displacement from the equilibrium

position.

(The distance from the equilibrium to

the crest or trough).

Anode The electrode where electrons are lost

(oxidized) in redox reactions.
