What is Air Conditioning?

If we are to define air conditioning we will have to say that it is the mechanical way of regulating the temperature, humidity, cleanliness and air flow inside a room or a building. The job of an air conditioner would be to control the temperature-humidity ratio at such a level that that it is both comfortable for us and is also healthful. As most air conditioners come with a filter it also clean the circulating air of the various contaminants like dust, soot, pollen, etc. Although not to the levels of an air purifier, air conditioners do in fact clean air considerably.

What an air conditioner unit actually does is it draws in air from a room or a building and passes it across that side of the refrigeration apparatus which is much colder and absorbs the heat in the air. How cool the refrigeration apparatus is, is determined by how a thermostat is regulated. For water-cooling airconditioning units, the heat is drawn away by the water flow. So fundamentally the principle is simple.

However, there are a number of things that are associated with a modern airconditioner, which makes it more than just a cooling device. In fact if it remains just a cooling device, it would be actually wrong to call it an air conditioning unit. Ideally it should provide a comfortable temperature inside the room, no matter how hot or how cold is it outside. So many air conditioners come with a heat pump whose function is to just reverse the refrigeration cycle. So when it is chilling cold outside, you can still be warm and cozy inside.

Although the rudimentary ideas of the concept of air conditioning can be traced back to the early decades of the nineteenth century it was only in the first half of the previous century that air conditioner as we see it was introduced. Since then air conditioner had little stopping and it has become an integral part of our life.

Although we generally tend to associate air conditioning with the comforts of life, it is also crucial to carry out several processes. For example certain operations like an open heart surgery can be conducted only under a controlled environment, and without air conditioner that would not be possible. Many industries, including the chemical and pharmaceutical industries cannot do without air conditioning. In fact it is hard to conceptualize today's world without air conditioning.

The Role of Nitric Oxide in Bodybuilding

Nitric Oxide, a key molecule manufacturered by the body, causes vasodilation (an expansion of the internal diameter of blood vessels), which in turn leads to increased blood flow, oxygen transport, delivery of nutrients to skeletal muscle and a reduction in blood pressure. An amino acid compound called arginine alpha-ketoglutarate (A-AKG) and arginine-ketoisocaproate (A-KIC) can boost short term Nitric Oxide levels. Increased strength and markedly improved stamina can also be expected. In fact, the results may be classified into three categories: 1) the promotion of an extended pump; 2) signaling muscle growth and speeding recovery; 3) increasing strength and stamina.

NO2 contains A-AKG and A-KIC, natural myodilators that may help boost nitric oxide levels in your body, thereby increasing blood flow, oxygen transport, and delivery of nutrients to skeletal muscle.

NO2 contains A-AKG and A-KIC which may help your muscles experience an extended pump.
NO2 contains A-AKG and A-KIC which may help your body signal muscle growth and speed recovery.
NO2 contains A-AKG and A-KIC which may help improve your strength and stamina.
NO2 utilizes the A-DS Advanced Delivery System which enhances absorption of the active compounds to insure uptake and help sustain powerful effects around the clock.

Who needs it and what are some symptoms of deficiency?
Everyone needs nitric oxide to carry out key physiological processes within the body. From a bodybuilder's perspective, nitric oxide supplementation may prove useful in increasing growth due to increases in blood flow to certain areas of the body. Further, men suffering from erectile dysfunction may also find supplementing with nitric oxide helpful.

Signs of deficiency include the inability to achieve and sustain erections, physical weakness and extreme fatigue. Most "nitric oxide" supplements contain the amino acid Arginine-alpha-keto-glutarate.

What are the side effects?
With any amino acid containing product, overdose is a possibility. Dosing with too much arginine can lead to diarrhea, weakness and nausea. Clear dosing guidelines have not been established, so it is best to do what is known as "tolerance mapping". Take a small dosage for one week, note the benefits and the side effects, and increase the dosage until the benefits are maximized and the side effects minimized. Over time the two will converge and you will hit the optimal dose.
