When you plug the vacuum cleaner into the outlet and
turn it on, the following happens:
1. First of all, the electric current will
operate the motor, which is attached to the fan,
which resembles an airplane propeller.
2. As the blades begin to turn, they will
force the air upwards, towards the exhaust port.
3. When the air particles are driven forwards,
the density of the particles will increase in front
of the fan and therefore decrease behind it.

The pressure drop that occurs behind the fan is
similar to the pressure drop when you take a drink
through a straw. The pressure level in the area
that is behind the fan will drop below the pressure
level that is outside of the vacuum cleaner.

This will create a suction inside of the vacuum
cleaner. The ambient air will push itself into the
vacuum cleaner through the intake port because the
air pressure that is inside of the vacuum cleaner
is much lower than the pressure on the outside.

Picking the dirt up
The stream of air that the vacuum generates is just
like a stream of water. The air particles that move
will rub against any loose dust or debris and if
it is light enough, the friction will carry the
material around the inside of the vacuum cleaner.

As the dirt continues on to the exhaust port, it
will pass through the cleaner bag. They tiny holes
in the vacuum cleaner bag are large enough to let
the air pass through, although too small for the
dust particles to fit through. Therefore, when
the air current gets into the bag, the dirt and
debris will be collected there.

You can stick the bag anywhere along the path
between the intake tube and the exhaust port, just
as long as the air current passes through.

Suction
The power of a vacuum cleaner’s suction will depend
on several factors. The suction can be stronger
or weaker depending on:
1. Fan power – In order to generate a
strong suction, the motor needs to turn at a good
speed.
2. Air passageway – When a lot of debris
builds up in the bag, the air will face a greater
level of resistance on the way out. Each particle
of air will move slowly due to the increase in
drag. This is the reason why a vacuum cleaner
works much better once you’ve replaced the bag
than when you have been using it for a while.
3. Size of the intake port – With the
speed of the vacuum fan being constant, the amount
of air that passes through the vacuum cleaner per
second is also constant.

Then, too, there were great changes in temperature. First everything was heated to a high temperature, then gradually became cool. Just think of the cracking, the crumbling, the upheavals, that such changes must have caused! You know some of the effects in winter of sudden freezes and thaws. But the little examples of bursting water pipes and broken pitchers are as nothing to what was happening in the world during those days. The water and the gases in the atmosphere helped along this crumbling work.

From all this action of rubbing, which action we call mechanical, it is easy enough to understand how sand was formed. This represents one of the great divisions of soil sandy soil. The sea shores are great masses of pure sand. If soil were nothing but broken rock masses then indeed it would be very poor and unproductive. But the early forms of animal and vegetable life decaying became a part of the rock mass and a better soil resulted. So the soils we speak of as sandy soils have mixed with the sand other matter, sometimes clay, sometimes vegetable matter or humus, and often animal waste.

Clay brings us right to another class of soils clayey soils. It happens that certain portions of rock masses became dissolved when water trickled over them and heat was plenty and abundant. This dissolution took place largely because there is in the air a certain gas called carbon dioxide or carbonic acid gas. This gas attacks and changes certain substances in rocks. Sometimes you see great rocks with portions sticking up looking as if they had been eaten away. Carbonic acid did this. It changed this eaten part into something else which we call clay. A change like this is not mechanical but chemical. The difference in the two kinds of change is just this: in the one case of sand, where a mechanical change went on, you still have just what you started with, save that the size of the mass is smaller. You started with a big rock, and ended with little particles of sand. But you had no different kind of rock in the end. Mechanical action might be illustrated with a piece of lump sugar. Let the sugar represent a big mass of rock. Break up the sugar, and even the smallest bit is sugar. It is just so with the rock mass; but in the case of a chemical change you start with one thing and end with another. You started with a big mass of rock which had in it a portion that became changed by the acid acting on it. It ended in being an entirely different thing which we call clay. So in the case of chemical change a certain something is started with and in the end we have an entirely different thing. The clay soils are often called mud soils because of the amount of water used in their formation.

The third sort of soil which we farm people have to deal with is lime soil. Remember we are thinking of soils from the farm point of view. This soil of course ordinarily was formed from limestone. Just as soon as one thing is mentioned about which we know nothing, another comes up of which we are just as ignorant. And so a whole chain of questions follows. Now you are probably saying within yourselves, how was limestone first formed?

At one time ages ago the lower animal and plant forms picked from the water particles of lime. With the lime they formed skeletons or houses about themselves as protection from larger animals. Coral is representative of this class of skeleton-forming animal.

As the animal died the skeleton remained. Great masses of this living matter pressed all together, after ages, formed limestone. Some limestones are still in such shape that the shelly formation is still visible. Marble, another limestone, is somewhat crystalline in character. Another well-known limestone is chalk. Perhaps you’d like to know a way of always being able to tell limestone. Drop a little of this acid on some lime. See how it bubbles and fizzles. Then drop some on this chalk and on the marble, too. The same bubbling takes place. So lime must be in these three structures. One does not have to buy a special acid for this work, for even the household acids like vinegar will cause the same result.

Then these are the three types of soil with which the farmer has to deal, and which we wish to understand. For one may learn to know his garden soil by studying it, just as one learns a lesson by study.

The Swedish Massage, which is also known as the classic or traditional massage is the most common massage therapy method and is usually preferred by the majority of people. It is characterized by long and flowing strokes which relax muscles, improve joint flexibility and aid in better circulation.

The first stroke is known as effleurage, involves long, gliding strokes from the neck down to the base of the spine or from the shoulder down to the fingertips. It is also done on the limbs with all strokes directed toward the heart to aid blood and lymphatic flow. The therapist uses his whole hand or a thumb pad. This technique is done for familiarization of the person's body

Next is petrissage that consists of the gentle lifting of muscles up and away from the bones, then rolling and squeezing them, with a gentle pressure. It generally involves rolling, squeezing, or pressing the muscles to enhance deeper circulation. It increases circulation through eliminating toxins from muscle and nerve tissue.

Friction, the third technique and the most forceful one is characterized by deep circular movements using fingertips applied near bony areas and joints and it relaxes the muscle fiber which enhances flexibility in muscles and joints.

After friction, another technique called tapotement is done. Tapotement is a series of quick forceful movements made by striking or tapping the muscles with the hand. It can be applied with a closed fist, fingertips and the edge of the hand. It releases tension and relieves muscle cramps.

Lastly, the therapist uses vibration or shaking that entails the pressing of hands on the back or limbs and shaking in a rapid motion for a few moments. It improves circulation and muscle contraction and is beneficial to people with low-back pain.

On the other hand, Ayurvedic massage originated from India and its aim is to create harmony and balance within the individual and it aids in the removal of toxins and rejuvenation of the body. It was not practiced publicly until Indian practitioners decided to roam around and give muscle, joint and back massages

Ayurvedic massage is based on a special system that includes the knowledge of Ayurvedic and Greek systems of medicine which is focused on Ayurvedic doshas and marmas or pressure points. Muslim massage techniques were also adapted in this system.

Ayurvedic massage techniques uses specific oils that suit your dosha and depends on your being. One is the Abhyanga-Garshana which comprises of skin brushing followed by an oil massage, Udwarthanam which is a slimming massage that uses herbal powders and the Ayurvedic foot massage which is a deep massage where the therapist uses his feet.

Now with enough knowledge on both Swedish and Ayurvedic massage, a person has of course the privilege to choose among the two which best suits his/her style of relaxation. But with both massages having unique techniques, the choosing part can be a little tricky though.

What is Swedish massage therapy? It is a technique designed to help the muscles in the body relax by applying pressure and then rubbing it in the same direction as the flow of blood returning to the heart.

Unlike other methods of massage therapy, this was first developed in the 18th century. It is also called the “classic massage” because it represents the Western way of relaxing those muscles.

The main purpose of the Swedish massage then and now is still the same. This is to increase the flow of oxygen in the blood so toxins are released from the muscles. These toxins include lactic and uric acid as well as metabolic waste.

What is Swedish massage therapy? It is a technique designed to help the muscles in the body relax by applying pressure and then rubbing it in the same direction as the flow of blood returning to the heart.

Unlike other methods of massage therapy, this was first developed in the 18th century. It is also called the “classic massage” because it represents the Western way of relaxing those muscles.

The main purpose of the Swedish massage then and now is still the same. This is to increase the flow of oxygen in the blood so toxins are released from the muscles. These toxins include lactic and uric acid as well as metabolic waste.

When this happens, circulation is increased without increasing the heart load. The ligaments and tendons are both stretched keeping them supple and pliable. This also stimulates the skin and nervous system and soothes the nerves at the same time. As a result, stress is reduced.

There are various techniques in the Swedish massage. Some examples of these are friction, effleurage, kneading, tapping, long strokes, vibrations and shaking motions. The therapist may use the fingertips, hands or palm to achieve maximum effect and of course, a little bit of bending and stretching.

During the session, the person has to undress and lie down on the mattress. He or she is then covered with a blanket and the only time it is opened is when the therapist has to massage that region of the body with oil so this will be absorbed by the body.

If you do not feel comfortable about being nude, bring some old loose clothes because the oil may stain fabrics.

Swedish massage therapy usually lasts for 60 to 90 minutes. Before the session begins, the therapist may check your complexion then choose the type of oil to use based on your skin type. If ever you want to increase or decrease the pressure, just say so and the therapist will adjust accordingly.

In the room, you may hear some soothing music playing in the background as this has been known to help people unwind. If you don’t like it, just tell them so they can play something else or just turn it off.

You might notice that the therapist would like to chat while working on you. Just like the music, if you don’t feel like talking, just tell them. Don’t worry, they won’t be offended.

Lastly, some people sleep during Swedish massage therapy. Again, that is perfectly fine because it has been known to happen.

Swedish massage therapy is considered to be the foundation of other types of Western massages. This is because the principles behind it are the same as when you try sports massage, seated chair massage, hot stone therapy, deep tissue massage or aromatherapy. If you like the way you were treated, try out the others the next time you drop by.

Before going for a session, check with your doctor if it is safe for you to do. You should also avoid eating a heavy meal before going in.

Swedish massage therapy is good. Once the session is over, you will feel relaxed and invigorated. Since you will feel thirsty afterwards, you better drink up. Some places offer water while others hand out warm tea. Whenever you are ready, it is time for you to get dressed and head on home.

What Anti-Aging Treatment Moisturizer Does To Your Skin?

People continue to look for the best skin moisturizer. It seems they never find the perfect one that can match the need of their skin. What is a skin moisturizer anyway? How does it affect the skin that makes people continue searching the best moisturizer? For anyone who hasn’t found the right moisturizer for their skin type, these are probably questions they continue to seek real answers for. Here are some information you might be interested learning in order to understand why you need moisturizer as your anti-aging treatment product to keep your skin looking and feeling supple, young, and radiant as always.

The skin is prone to damaging elements.

The skin is prone to drying because of many damaging factors you can get outside, such as sun light, weather changes, wind, friction, toxins, and many other elements. These elements not only damage the skin outer layer but make it dry, cracked, and develop fine lines. The inner layer of the skin needs proper hydration in order that the outer layer maintains suppleness it needs to look young and refreshed. A good moisturizer will help protect the skin from the damaging elements while it lubricates the outer part to develop premature aging signs.

Your skin has natural lubricants, in the form of sebum and water. Sebum is the fat being produced by the skin’s sebaceous glands, which are found in your pores or hair follicles. Tiny, light hairs are found in these follicles where behind each hair is found sebaceous gland. A good moisturizer that you should be looking must be similar to sebum’s molecular level. With this idea, it should be easy for you to spot a good moisturizer among the bad ones.

So, what is a good skin moisturizer?

A good skin moisturizer should contain oils similar to your skin’s sebum. When applied this should be quickly absorbed by your skin without the greasy feeling at all. Because it is readily absorbed, it instantly protects your skin outer layers while it hydrates its inner layers. And the best part is? It leaves no clogging to your skin’s pores.

What is a bad moisturizer?

A moisturizer that you shouldn’t be looking for is products that consist of any petroleum based oils, such as mineral oil, petrolatum, and paraffin. These are no way similar to your skin’s sebum. If you use this kind, it won’t give your skin the benefits it needs. Instead, it will clog up your pores, leave greasy feeling, and can lead to blemishes. If used for a long time, it can change your skin’s pH balance, thereby making it susceptible to infections.

How moisturizer should be applied?

Using a good moisturizer cream or lotion is a fundamental part of anti-aging skin care treatment. It should be applied daily and will be best if done after your cleansing or showering. If you use skin moisturizers which contain protein complexes and antioxidants, this is even better. Scientific studies suggested that antioxidants are best agents to protect your skin from free radicals, which are provided by different damaging elements.

A moisturizer with lots of protein complexes and antioxidants should help in neutralizing these free radicals, therefore avoiding your skin’s fibers and cells from getting damaged. So, when it comes to choosing the best anti-aging treatment moisturizer product, you should remember looking for one that does not only contain oils similar to sebum but one that has different antioxidants, proteins, and antibacterial agent.
