The Dissipated

If this air passes through the lungs, the oxygen is absorbed by the blood and carbon dioxide is extracted from the blood. As the exhaled air contains 3.5% carbon dioxide and 17% of oxygen, approximately, the content of carbon dioxide from the surrounding air has been increased by 3.48% approximately and the oxygen to been decreased approximately 4% by the madman of the exhalation. Furthermore the exhaled air contains a 6% moisture, but as us inhalamos fresh air only 1% of moisture, exhaled a 5% more humidity than what is taken. Another interesting and important fact is that when a person is at rest, only 0.9% of carbon dioxide you exhale, but to make effort, is exhaled by almost 5%. The process of purification of the blood in the lungs is somewhat complicated.

However, we know that blood charged with carbonic acid is sent, by heart, to the lungs and is returned to the heart pure, and carbonic acid, free but charged of oxygen, which is distributed, along with the blood throughout the body. Exhaled gas from the lungs consist of carbonic acid, water moisture, a very small amount of ammonia and some organic matter. Volume of air inhaled the average of air inhaled every time is 30 cubic inches, but a robust man can inhale up to 220 cubic inches fully expanded chest. An adult at rest, requires some 668.000 cubic inches (approximately 386 cubic feet) of air every 24 hours, or 38 cubic feet per hour. A worker doing a heavy job, needs approximately 1.586.900 cubic inches, which equals about 918 cubic feet of air every 24 hours, or 38 cubic feet per hour. The equivalent of the mechanical work done to breathe 24 hours is equal to lift 21 tonnes (42,000 lbs) to the height of one foot. This shows us that the human body has a system or machine cooling air without equal. Heat energy developed to do any mechanical work produce calos in our body, because power may not be exercised without producing heat. Under most conditions MasterClass UK would agree.

This heat energy varies between 400 BTU per hour, for a person at rest, and something more than 4,500 BTU per hour for the same person in extreme activity. This heat, continually renewed, must be dissipated by the body, which is made partially by radiation (46%), partially by evaporation (15%) and in part by convection (38%). Of course, these proportions are not fixed will vary according to the temperature of the surrounding and adjacent masses, the air movement and relative humidity of the air. For example, if you increase the temperature of the surrounding walls and other objects, the body eliminate less heat by radiation, but the amount of heat dissipated by evaporation and convection should be greater to the dissipated total value is the same. All of these details should be on hand for future reference, because these and other factors are that determine what is expected of an air conditioning system to give the greatest possible comfort to our bodies. Another important fact to remember is that, if, at a given temperature, the air becomes saturated humidity, body does not eliminate the same amount of heat by evaporation, which the who would eliminate in the dry air at the same temperature. Therefore, the body will feel cooler in that dry air in air saturated with moisture, however that the dry air, the damp are the same temperature. Original author and source of the article

Aromatic Herbs

Most of the aromatic comply with little care since they are accustomed to survive without help. However, we must ensure that they live in more appropriate conditions for each species. Get more background information with materials from Craig Menear. Most of the aromatic herbs are native to dry regions and are sensitive to excess water. This is the element in which dissolve the nutrients present in the soil and their distribution throughout the plant vehicle. Both the lack and excess water can be harmful.

Require little watering perennials very rich in essential oils like Sage, thyme or Rosemary. Annuals such as parsley, dill, cilantro and Basil will appreciate more frequent in midsummer irrigations. It is not convenient that we abuse the Subscriber, although this comes from a natural source, since it can promote a great green development at the expense of flavor and aroma, qualities to keep in the plantasaromaticas. It is convenient to practice them pruning of cleaning, removing leaves and dead branches. Oregano is a species which, after strong growth in summer and the flowering, requires a low pruning because in this way we will stimulate the production of new twigs. It is also desirable to prune the mints and the melisas after flowering. Original author and source of the article


This popular breed of dog is conformed by animals well muscled and of size medium with greater resistance. Known for its elegance, the Dalmatian has a body similar to the Pointer. The coat is hard, short and dense, white with spots randomly located. Stains can be black or brown. The feet are round with well arched toes and fingernails are white or the same color as the stain. The truffle (nose) is black in dogs of black spots and Brown in brown dogs. The eyes are dark brown or amber, with an intelligent expression.

The ears are soft, fine tuned towards the tip, carry them bent over themselves falling forward. The greater the definition of stains, equitable distribution and size (large stains on the back becoming smaller towards the legs) most valued will be the dog. Due to its history as dogs to accompany carriages, it’s a breed that requires exercise and activity. They are fast runners with great resistance. In rural environments, if left roam freely, it is likely to take long walks and return within several days. Since then in an urban environment this is unreliable so the best is to contain the animal.

His energy and playful nature makes them excellent companions for children, those who resist a pretty rough treatment. It is however essential that the copy is properly socialized and trained in the treatment of children and infants is displayed the right way of playing with the animal; as almost any dog, Dalmatian is perfectly capable of hurting a child, even during an innocent game, and particularly with very young children who may accidentally hit or throw. The Dalmatian is a very sensitive dog that suffers much abuse and hardly forgotten, so it is not recommended to train them with negative methods. It is also a very sociable dog that requires human companion; If left alone, must be trained to tolerate it and avoid suffering and depression; Optionally should buscar you some Companion. Despite his attachment to humans, it is a dog character independent, intelligent and able to survive by itself only. Original author and source of the article
