Sunlight for Your Life

All life on the planet and everything in nature is dependent on the sun. Without the sun, there would be no life on the planet. All life is dependent on the sun. Plants convert the sunlight into energy, and all animals need plant life or other animals in order to live. All life in nature is dependent on the sun. We as humans are part of nature. We need sunlight just like everyone else.
Sunlight is essential for your life and health. This often brings up the concern of skin cancer. People are told the sun causes skin cancer and they should wear sunblock to prevent skin cancer. This is a big fat theory of the medical symptom and disease care profession. Skin cancer is on the rise because people are supposedly spending more time in the sun, and this is the supposed "proof" that skin cancer is caused by the sun. Did the experts happen to notice that most cancer is on the rise? Does the sun cause these cancers as well?
Well, my friends, I have a question for you. How many other bad things are on the rise that people are doing? Lots. Just because the sun hits the skin, the powers that be say it means that is the one thing that "causes" skin cancer. They are looking for the one cause and one cure. Remember, there is no one cause of anything. There are only contributing factors.
In my opinion, it is not the sun that contributes to cancer, but being burned by the sun. Most people get no exposure to the sun for months; then they play weekend warrior and go out in the sun all weekend, often getting burned. My inner knowing tells me it is this burning that is a major contributing factor to skin cancer, not the actual sun exposure.
So if you do not build up to being in the sunlight, and you know you will be in the sun for a long time, use a chemical-free sunblock.
The irony about sunblock is the stuff most people use actually contains a chemical that is known to cause cancer. The FDA says PABA is a known carcinogen, or causes cancer and yet it is in most sunblocks. How ironic. There are PABA-free sunscreens that use "new" different chemicals. My thought is that those chemicals that replace the PABA will soon be identified as carcinogens as well. Just give them time. Even PABA was labeled "safe" by the FDA at first
.
My recommendation: get a good chemical-free sunblock. Many health food stores will have them. Or you can find a place near you that sells them on the web. Avalon Organics is the sunblock I recommend and use. Unfortunately, they are not available everywhere right now.
The easiest way to get sunlight is go outside. Go outside every day without contacts or any type of glasses and have large amounts of your skin exposed to the sun. For you this might not be feasible, because you live some place where there is a thing called winter. So an acceptable alternative is getting some quality full spectrum light bulbs for your work and home. These are light bulbs that put out light similar to the sun. You can order them online as well, full spectrum solutions are the brand I use. But be careful; not all full spectrum bulbs are created equal. Most of the full spectrum bulbs in traditional stores are not much of an improvement over ordinary lights.

A fun alternative is going south for the winter. Go someplace where you can hang out in the sun without glasses or contacts, with much of your skin exposed to the sun.
Either way, you need sunlight all year round to be Totally Healthy.

CHROMIUM HELPS FIGHT THE CAUSES OF DIABETES

It is used to assist
in muscle-building, but now research has revealed that chromium
can help overweight people control insulin levels. Chromium
helps the body's response to insulin, this makes it better to
keep the levels of blood-sugar in check.

The most effective form of this supplement is chromium
picolinate. A 35-microgram dose daily is sufficient. Check with
your doctor to see if you need to increase the dosage to 200
mcg, if you have a diabetic condition.

CALCIUM FOR STRONG BONES AND WEIGHT LOSS

Many men are not
getting the daily allowance of 1,000 mg. A cup of milk has only
300 mg. It has been found that men with high calcium levels
weigh less than men with low levels of calcium.

A dosage of 1,200 mg is preferred. Make sure you have calcium
citrate it is the purist form. Take half dose in the morning and
half at night. Avoid coral calcium it has some impurities.

If you get your 3 servings of calcium daily you won't need any
more. You could exceed your maximum daily intake 2,500 mg.

BORON WILL AID IN THE DEFENSE OF PROSTATE CANCER

A high level of this mineral will
help reduce the chances of getting prostate cancer by 65%. US
males have a one of the lowest boron levels compared to other
countries.

Only 3 milligrams daily help fight cancer and studies show also
improve memory and concentration.

Boron is not in stock at all health food stores. It is also
naturally found in raisins and almonds.

Ten Of The Best Supplements That Men Need For Optimum Nutrition

There are many nutrition supplements at your local health food
store. So many to choose from so confusing which ones are the
right ones. How many should you take? Here you will learn what
you need to take for the best health benefits. A word of warning
here although these products are convenient getting some of your
nutrition in liquid form or capsules is only recommended when
you can't eat properly or you feel you are not getting your
proper daily nutrients. The companies that make the products
themselves mostly fund the studies of meal replacements, and the
manufactures usually test their supplements against similar
supplements not the benefits of whole foods.

Why Child Bearing Is Healthy



How have women specifically put themselves outside of their natural context to make themselves more susceptible to cancers?

The average mom gives birth to about two infants. Although this is an intelligent number from the standpoint of population control, it is unnatural in that by not continuing to have pregnancies and to nurse (which stops ovulations) she will ovulate an incredible 438 times during her lifetime.

On the other hand, a woman in the primitive natural setting who may not even know what causes pregnancy or how to prevent it even if they wanted to, would have started menstruating and ovulating at age twelve and would have delivered nine babies and breast-fed them over the course of her reproductive career. Breast-feeding can continue for children in a totally natural setting for up to five or more years of age. The combination of pregnancy along with breast-feeding in the premodern setting would have decreased the number of ovulations that a primitive mother would have had to about nine.

This means that today women cycle through their menstrual periods an abnormal number of times, subjecting their bodies to surges of estrogen 50 times greater than our primitive ancestors living in a natural setting.

Many cancers of women are sensitive to high levels of female hormones.

For example, breast cancer is sensitive to estrogen. In dogs, simply removing the ovaries can often prevent or halt the progress of mammary cancer. Tamoxifen in humans is used to block estrogen activity within the mammary glands and thus is believed to exert its protective effect in this way. (This pharmaceutical agent can, however, increase the risk of uterine cancer to about the same degree that the risk of breast cancer is reduced!)

The resting periods of lower estrogen levels that women experienced in the premodern setting served a protective effect to spare organs and tissues from cancer. Women who nurse for a total period of time of even as little as two years are known to have a decreased incidence of mammary cancer.

This excess ovulation hypothesis is the likely explanation for the tragic phenomenon of modern female cancers. When humans decide to flout and repudiate nature by interfering with natural biological design, disease will always be the consequence.

If the problem is a departure from nature, then the solution is a return to it. Here are some options:

1. Refer to the Wysong Optimal Health Program for guidelines on life choices that can enhance overall health and thus hormonal health

2. Emphasize fresh raw foods in the diet and avoid processed foods as much as possible.

3. Eliminate hydrogenated oils and refined sugars. Hydrogenated oils displace healthful dietary fats and have been shown to be carcinogenic, and sugars can stimulate a rise in estrogens.

4. Try to use organic foods as much as possible and avoid synthetic materials in cosmetics, at home and in the workplace to help reduce exposure to environmental estrogens.

5. Do not attempt “low fat” or “low cholesterol” fad diets that often create dependence upon processed carbohydrates and seriously reduce important natural dietary fats and essential fatty acids.

6. Increase the consumption of natural vegetable foods containing phytoestrogens which tend to counteract estrogens.

7. Avoid hormone medications if at all possible.

8. Explore natural birth control measures.

9. Nurse your babies for as long as you can.

Modern life presents many choices, freedoms and rights. Tinkering with child bearing, however, is a choice that is not without consequences. Women need to be aware and take the steps necessary to make sure the choices they make do not also bring with them the increased risk of serious modern diseases.

INVERTER

An inverter is an electrical device that converts direct current (DC) to alternating current(AC); the converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits.
Solid-state inverters have no moving parts and are used in a wide range of applications, from small switching power supplies in computers, to large electric utility high-voltage direct current applications that transport bulk power. Inverters are commonly used to supply AC power from DC sources such as solar panels or batteries.
There are two main types of inverter. The output of a modified sine wave inverter is similar to a square wave output except that the output goes to zero volts for a time before switching positive or negative. It is simple and low cost (~$0.10USD/Watt) and is compatible with most electronic devices, except for sensitive or specialized equipment, for example certain laser printers. A pure sine wave inverter produces a nearly perfect sine wave output (<3% total harmonic distortion) that is essentially the same as utility-supplied grid power. Thus it is compatible with all AC electronic devices. This is the type used in grid-tie inverters. Its design is more complex, and costs 5 or 10 times more per unit power (~$0.50 to $1.00USD/Watt).The electrical inverter is a high-power electronic oscillator. It is so named because early mechanical AC to DC converters were made to work in reverse, and thus were "inverted", to convert DC to AC.

Ideal power equation of transformer

If the secondary coil is attached to a load that allows current to flow, electrical power is transmitted from the primary circuit to the secondary circuit. Ideally, the transformer is perfectly efficient; all the incoming energy is transformed from the primary circuit to the magnetic field and into the secondary circuit. If this condition is met, the incoming electric power must equal the outgoing power:
If the voltage is increased, then the current is decreased by the same factor. The impedance in one circuit is transformed by the square of the turns ratio.For example, if an impedance Zs is attached across the terminals of the secondary coil, it appears to the primary circuit to have an impedance of (Np/Ns)2Zs. This relationship is reciprocal, so that the impedance Zp of the primary circuit appears to the secondary to be (Ns/Np)2Zp.

Leakage flux


Leakage flux of a transformer
Main article: Leakage inductance
The ideal transformer model assumes that all flux generated by the primary winding links all the turns of every winding, including itself. In practice, some flux traverses paths that take it outside the windings. Such flux is termed leakage flux, and results in leakage inductance in series with the mutually coupled transformer windings. Leakage results in energy being alternately stored in and discharged from the magnetic fields with each cycle of the power supply. It is not directly a power loss (see "Stray losses" below), but results in inferior voltage regulation, causing the secondary voltage to fail to be directly proportional to the primary, particularly under heavy load. Transformers are therefore normally designed to have very low leakage inductance.
However, in some applications, leakage can be a desirable property, and long magnetic paths, air gaps, or magnetic bypass shunts may be deliberately introduced to a transformer's design to limit the short-circuit current it will supply. Leaky transformers may be used to supply loads that exhibit negative resistance, such as electric arcs, mercury vapor lamps, and neon signs; or for safely handling loads that become periodically short-circuited such as electric arc welders.
Air gaps are also used to keep a transformer from saturating, especially audio-frequency transformers in circuits that have a direct current flowing through the windings.
Leakage inductance is also helpful when transformers are operated in parallel. It can be shown that if the "per-unit" inductance of two transformers is the same (a typical value is 5%), they will automatically split power "correctly" (e.g. 500 kVA unit in parallel with 1,000 kVA unit, the larger one will carry twice the current).

Induction law of Transformers

The voltage induced across the secondary coil may be calculated from Faraday's law of induction, which states that:
where Vs is the instantaneous voltage, Ns is the number of turns in the secondary coil and Φ is the magnetic flux through one turn of the coil. If the turns of the coil are oriented perpendicular to the magnetic field lines, the flux is the product of the magnetic flux density B and the area A through which it cuts. The area is constant, being equal to the cross-sectional area of the transformer core, whereas the magnetic field varies with time according to the excitation of the primary. Since the same magnetic flux passes through both the primary and secondary coils in an ideal transformer, the instantaneous voltage across the primary win
Taking the ratio of the two equations for Vs and Vp gives the basic equation for stepping up or stepping down the voltage.
Np/Ns is known as the turns ratio, and is the primary functional characteristic of any transformer. In the case of step-up transformers, this may sometimes be stated as the reciprocal, Ns/Np. Turns ratio is commonly expressed as an irreducible fraction or ratio: for example, a transformer with primary and secondary windings of, respectively, 100 and 150 turns is said to have a turns ratio of 2:3 rather than 0.667 or 100:150.

Basic principle of Transformers

The transformer is based on two principles: first, that an electric current can produce a magnetic field (electromagnetism), and, second that a changing magnetic field within a coil of wire induces a voltage across the ends of the coil (electromagnetic induction). Changing the current in the primary coil changes the magnetic flux that is developed. The changing magnetic flux induces a voltage in the secondary coil.
An ideal transformer is shown in the adjacent figure. Current passing through the primary coil creates a magnetic field. The primary and secondary coils are wrapped around a core of very high magnetic permeability, such as iron, so that most of the magnetic flux passes through both the primary and secondary coils.

TRANSFORMERS

A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors—the transformer's coils. A varying current in the first or primary winding creates a varying magnetic flux in the transformer's core and thus a varying magnetic field through the secondary winding. This varying magnetic field induces a varying electromotive force (EMF), or "voltage", in the secondary winding. This effect is called mutual induction.
If a load is connected to the secondary, an electric current will flow in the secondary winding and electrical energy will be transferred from the primary circuit through the transformer to the load. In an ideal transformer, the induced voltage in the secondary winding (Vs) is in proportion to the primary voltage (Vp), and is given by the ratio of the number of turns in the secondary (Ns) to the number of turns in the primary (Np) as follows:
By appropriate selection of the ratio of turns, a transformer thus allows an alternating current (AC) voltage to be "stepped up" by making Ns greater than Np, or "stepped down" by making Ns less than Np.

Modern uses of Dynamo

Dynamos still have some uses in low power applications, particularly where low voltage DC is required, since and a alternator semiconductor can be inefficient in these applications. Hand cranked dynamos are used in clock work radio hand powered flashlights, mobile phones rechargers, and other human powered eqipmentto recharge batteries

Siemens and Wheatstone dynamo (1867

The first practical designs for a dynamo were announced independently and simultaneously by Dr. Werner and Charles wheastone On January 17, 1867, Siemens announced to the Berlin academy a "dynamo-electric machine" (first use of the term) which employed self-powering electromagnetic field coils rather than permanent magnets to create the stator field.On the same day that this invention was announced to the Royal Society Charles Wheatstone read a paper describing a similar design with the difference that in the Siemens design the stator electromagnets were in series with the rotor, but in Wheatstone's design they were in parallel.The use of electromagnets rather than permanent magnets greatly increases the power output of a dynamo and enabled high power generation for the first time. This invention led directly to the first major industrial uses of electricity. For example, in the 1870s Siemens used electromagnetic dynamos to power electric arc furnaces for the production of metals and other materials.

industry. Further improvements were made on the Gramme ring, but the basic concept of a spinning endless loop of wire remains at the heart of all modern dynamos.

Gramme ring dynamo

Small gramme dynamo, around 1878
Zenobe gramme reinvented Pacinotti's design in 1871 when designing the first commercial power plants, which operated in Paris in the 1870s. Another advantage of Gramme's design was a better path for the magnetic flux, by filling the space occupied by the magnetic field with heavy iron cores and minimizing the air gaps between the stationary and rotating parts. The gramme dynamo was the first machine to generate commercial quantities of power for

Dynamo as commutated DC generator

After the discovery of the AC Generator and that alternating current can in fact be useful for something, the word dynamo became associated exclusively with the commutated DC electric generator, while an AC electrical generator using either slip rings or rotor magnets would become known as an alrternator.
An AC electric motor using either slip rings or rotor magnets was referred to as a synchrounous motor and a commutated DC motor could also be called an electric motor though with the understanding that it could in principle operate as a generator.

Brush dynamo

Charles F. brush assembled his first dynamo in the summer of 1876 using a horse-drawn treadmill to power it. U.S. Patent #189997 "Improvement in Magneto-Electric Machines" was issued April 24, 1877. Brush started with the basic Gramme design where the wire on the sides and interior of the ring were outside the effective zone of the field and too much heat was retained. To improve upon this design, his ring armature was shaped like a disc rather than the cylinder shape of the Gramme armature. The field electromagnets were positioned on the sides of the armature disc rather than around the circumference. There were four electromagnets, two with north pole shoes and two with south pole shoes. The like poles opposed each other, one on each side of the disc armature.
