Sew that You Didn't Know to Learn

Did you know that you are possible to make insecticide with lemons?
You are this way, this is achieved with the help of an extracted liquid of the lemon (citrus limonium), an oleum of your fresh shell of pale or green xanthic, volatile yellow color, soluble in alcohol and not very soluble in the water.
This oleum is also used as perfuming and saborizante in the alimentary industry, cosmetics, products of clean-up and until in odorants.

Did you know that the blind" "hen is played for about 2000 years?
According to data that are had of this infantile popular game, this well-known game generally as the blind" "hen, you were played more than 2,000 years recently in old Greece.
You were known with similar names in different parts of Europe, for example, in Germany he/she was known as Blinderkuh (you vacate you blind), in Italy he/she called himself fly cieca (blind fly), and in Sweden Blindbock (blind horse).

Did you know that the music in the work improves the productivity?
You are not about any joke. A studio has endorsed this thesis that "the music in the work improves the productivity."
A realized studio recently for the University of Sheffield in the United Kingdom suggests that to hear music in the offices can improve the productivity and the state of the workers' spirit, since it allows to manage the well-being in the daily life.

Wise that the contamination can damage your brain?
If you breathe the fume that you/they say goodbye to the files maybe during one hour you don't only suffer a headache.
A recent investigation assures that still a petty exhibition to the gases emanated by the fuel can affect the form like the brain works.
According to the studio published in the magazine Particle and Fibre Toxicology (Toxicology of Particles and Fibers), the fume of combustion of the diesel induces a stress response in the brain activity.
Previous investigations had determined that the petty particles (called nanopartículas) that we breathe in the polluted air can arrive to the brain.
However, this is the first time that are possible to demonstrate in a studio that the inhalation of pollutants can alter the brain activity.

Did you know that taking 2 up-to-date cerevezas can reduce the risk of Alzheimer?
According to the conclusions of a studio entered by the physicians of the Department of Nutrition, Bromatología and Toxicology of the University of Alcalá of Hayfields (UAH) María José González and Isabel Meseguer
The work, titled "The beer like dietetic font of silicon and your protective effect in front of the intoxication for aluminum: you influence on the absorption and the buildup of this neurotoxic" metal, you have been carried out with experimentation animals, concretely mice, and you are not still in phase of human experimentation, the physician has explained to Meseguer.

Did you know that the fiber of the foods is not digested in the human body?
You are this way the dietetic fiber it cannot be digested by the human organism. This fiber is a group of components that you encunentra in the foods of vegetable origin, such as cereals, fruits, vegetables and vegetables.
The one that the fiber cannot be digested is for that the organism doesn't count the enzymes that make this feature and they use it, however, although you cannot digest it directly, our intestine has the help of the bacterial flora that ferment the fiber and you decompose it in diverse elements: gases and fatty acids of short chain that exercise an important feature in our organism.

Did you know that the clepsydras are clocks of water that they were used in Egypt from 1400 AC?
You are this way, the clocks of water or clepsydras date of the Egyptian antiquity and they were used especially during the night, when the sundials lost your utility.
The first clocks of water consisted on a ceramic vessel that contained water until certain level, with a hole in the base of an appropriate size to assure the exit from the liquid to a certain speed and, therefore, at one time preset. The vessel prepared in your interior of different trademarks of such a luck that the level of water indicated the different periods, so much daily as nocturne.

Did you know that the vencejo common of Europe and can Asia last up to 3 years in the air?
You are this way, for that reason it is the bird that more time passes without stepping the earth. They can imagine up to 3 years without stepping the earth!.
Because well they are made to pass all your life in the air, they eat, they sleep and they copulate flying. As they make it? They are designed in that since way they have falciform wings, short queue of not very deep fork, very wide and big mouth finished off with a petty peak, blackish plumage with a white or gray petty portion under the peak, very short paws and tiny claws. And since your paws are weak tán you experience great difficulty in overcoming the flight when these birds for accident fall to the floor.

Why do you curl the hair with the dampness?
In the hair there are proteins, and these they are formed by amino acids. The amino acids would be as the links of the chain that it are the protein. This chain can establish stable unions among different links forming three-dimensional structures.
The amino acids contain atoms of sulfur. The atoms of sulfur can form bridges among different amino acids that you/they call themselves bridges disulfide.

Do You Know?

Do you know for that Jewish Easter always coincide with the Christian?
Jesus was Jewish, following the tradition went to Jerusalem to celebrate Easter (pesaj), you were when what we know as the last dinner took place and when ending the festejos they killed him.
From the Council of Nicea (325 d.C.) Easter of Resuscitation takes place following Domingo to the moon full with March (spring equinox) 21, or at the first that you have after that date. You are about a variable date that also determine all the movable dates of the liturgical year.

Which the longest word is?
Electroencephalogram has 23 letters and you are the longest word that he/she appear in the dictionary of the Actual Academy of the Tongue.

Do you know like the blind men dream?
The neurofisiólogos has checked that they should lapse at least five years from the forfeiture of the vision so that the brain acquires the setup encefalográfica of a blind person. This is due to that continue working systems of neurons during that first five year period that, well through the memory or by means of some channel, they make possible the arrival of stimuli to the field of the brain in charge of the vision, concretely to the back lobes of the skull.
On the other hand, each person dreams of agreement of your organization sensopercitiva, that is to say, depending from how you receive the stimuli. This is valid also for the blind men that pick up the sensations through other channels, as the hearing, the taste, the smell and the tact. The brain gathers the information of where you can. This way, in a blind person the dream accomodates the same sensations from birth, that when you are awake. He/she can dream that you play soccer or that you are in the field; but what feel, for example in this last case, you are how the grass is of wet or the fragrancy of the breeze that he/she receive your smell.
More problematic you are the analysis of the dream of those people that lost the view less than five years ago, because they can receive during the periods oníricos visual stimuli that probably extract of the memory. These images go demeaning with the time, and they lose color and articulation like an old picture. You have been observed, however that when you are about highly creative fellows, these end up conserving all your life both modalities of dream.
Do you know that you are and like you are formed the fog?
The fog is a meteorological consistent phenomenon in very low clouds, at level of the floor and formed by very petty particles of water in suspension. Most of the fogs takes place when evaporating the dampness of the floor, what cause the ascent of wet air that condense giving place to the formation of these low clouds when being cooled down. The fog bears the decrease of the conditions of visibility in surface. The dispersion of the light in the particles of water that they form the fog you favor the visibility in yellow wavelengths used in lighthouses and lights antiniebla.
The fog differs of the mist for your density like aerosol and giving a Visibility of less than 2 km. You are classified according to the origin of the cooling that gave origin to the condensation:
* Radiation fog: you happen after the setting of the sun, when the floor loses heat through the emission of infrared radiation in a cloudless (of being present, the clouds would avoid that the heat escapes to the space) night. Then, the cooled floor produces condensation in the near air to the floor, through the thermal conduction process. This type of fog is communio in autumn in the countries of temperate climate, you usually have a thickness of 1m (although the whirling can make that you rise, and you are of short duration.
* Fog of wind: you take place when masses of air loaded with dampness pass on cold floors, that which cool the same air. This phenomenon is communio in the costs, when the tropical lukewarm air meets with more waters of latitudes. You are also communio when a warm front moves on an area with a considerable quantity of snow.
* Fog of vapor: you are given when cold air moves on hotter waters. The vapor of the water enters in the atmosphere for evaporation processes, and the condensation is given when the point of dew is reached. This event is communio in polar areas, lakes of considerable size, and to the end of the autumn and start of the winter.
* Precipitation fog: you are when you rain, and the low air the cloud is relatively dry. This makes that the rain drops evaporate and form vapor of water that cool down, and when reaching the point of dew, you transform into fog.
* Hillside fog: you are formed when the wind blows against the hillside of a mountain or another geologic similar formation. When ascending in the atmosphere, the dampness condenses. You are for this reason that many times the mountainous summits appear cloudy.
* Valley fog: you are formed in the valleys, usually during the winter. You are investment outcome of temperature, caused by cold air that settle in the valley, while the air warm raisin above this and of the mountains. You are basically about radiation fog confined by an accident orográfico, and it can last several days, if the climate is I calm down.
* Fog of ice: you are any type of fog in which the drops of water are frozen in form of minuscule ice crystals. Usually, this requires of temperatures quite below the freezing point, that which make that they are common to arctic and antarctic areas. In occasions, petty quantities of these glasses throw to earth, like you happen in Barrow, Alaska. In having determined areas this fog it is known as dorondón or boira dorondonera.
Why do the roosters sing to the dawn?
The roosters, territorial birds, demonstrate your might by means of the strutting, the swell and bigger coloration of your juncture and the defiant songs. Attitudes that will carry out whenever they see inside your territory .o harassing some of your females - to another male rival. In a henhouse, space, in general of having reduced dimensions, any rooster nothing else to wake up goes in the obligation of demonstrating to the whole corral that continue being the dominant core; and if the silence doesn't answer to the defiant song, a fight, phonetics will come in the first place and physics next, with the vacuuming roosters to the seat of honor. For such a reason, you are not frequent to find several cores in oneself henhouse, unless you have enough hens to distribute.
As they are formed the physiques in the artificial fires?
All the devices that intervene in some artificial fires have two fundamental parts - apart from the stick or support -. One of them is the head propulsora that depending on the quantity of gunpowder, you make go up the rocket more or less. The other component is a realm (from among 50 and 350 mm) that accomodate in your interior different balls that, according to your composition, they will produce a color or another when bursting. These balls explode thanks to that you are a bag with wired gunpowder to the wick in the heart of the realm that contain them. The physiques that are formed depend on the allocation milimétrica of the color balls I jag of this realm. Most is already physiques mounted in China.

How are they formed the lines of colors in the pasta of teeth?
The operation of the two-colored pasta of teeth doesn't have a lot of mystery... once the trick is known.
Inside the tube of the dentifrice there is a petty deposit in turn with tiny holes where the colored pasta are.
When you crowd together the tube so that the dentifrice comes out, the white pasta passes to pressure by the means of the deposit, while the color pasta makes it through the holes, lining the product when exitting.
Although now it is habitual to see pasta of teeth of loud colors, the pioneer trademark in using this technique was Signal, in 1961.
Would you have a human clone the same prints dactilares that the original?
Some simplifications that are made when defining what a clone is they induce to error. According to the expert in transgénesis Lluis Montolíu: "A human clone would be a to be created starting from nuclear" DNA of a cell mother. In him "only the 98% of the individual's" genetic information travels; the remaining 2% of the genetic code comes from the cytoplasm, and in the shotgun technique technique it is not used. That is to say, two clones are different to each other in 2% of your genetic content.
Therefore, the scientists and experts prefer to speak of "animals reconstructed by nuclear" transfer that are more correct. In fact, genetically they are "more clonic" the twin monocigóticos for that both share as much the nuclear DNA as the citipoplasmático. But neither even so they have the same print dactilar, because in they influence it the environmental conditions, and these are never same for both.

Why do they stick the fingers to the ice?
The ices that we take out of the freezer are to a temperature of some below zero 20 centigrade grades. When we play them, we observe that our fingers usually stay pasted them. The scarce dampness that you are on the skin freezes instantly when you enter in contact with that congealed petty block and the water will only be able to detach them meetly.
That same you happen, although in a less accused way, when we play a cubitera inside with ices. And the effect is much more patent as much as better pipeline of the heat you are the material with which that cubitera has been manufactured. That is to say, the fingers are more pasted in one of metal that in other, for example, of plastic, and in this more than in a wooden one.

Why

Why are there times that we are reflected in the water?
In occasions when we are in some he/she laughed or lake is reflected our image in the water.
This happens because the light of the sun that arrives to the water is distributed in three ways.
A part is absorbed in form of heat.
Another part crosses it, straying.
To this phenomenon he/she is called refraction.
And it finishes it part he/she is reflected.
The reflection takes place since in the surface of the water this he/she behaves as a mirror.
When the water this in calm, many times we can see our image sharply reflected in the water.

Why is the sun of half night visible?
The action of the sun on the surface terrestrial taking their maximum intensity in the equatorial regions, falling progressively in address to the poles, in those that you grieve notices the change.
The sun of half night is visible because, as the axis of rotation of the earth it is not vertical, but oblique, during the period of solstice of each pole the sun stays visible uninterruptedly during the 24 hours of the day.
The solstices are those moments of the year in those that the sun reaches its maximum southern position, the name it comes from Latin and it means still sun.

Because the silver is darkened? what I always wonder
The cutleries, jewels and other silver objects are darkened with the step of the time, it is necessary to clean them so that they recover their previous aspect again.
The silver is a noble metal for that that not that he/she doesn't react with the other elements, it cannot be oxidized.
So much the gold, as the platinum and the silver is noble metals, for the little interaction that you/they have with the other substances, although that doesn't mean that they don't react.
The silver is not oxidized, he/she doesn't react with the oxygen of the air, but if it is darkened because he/she reacts with the sulfur that is in the atmosphere with the form of I sulfurate of hydrogen, a gas product of the combustion of the coal and of the petroleum.
The silver when reacting with the sulfur, is formed I sulfurate of silver that steams up the silver.
With the time he/she leaves darkening, the light also speeds up the process, since the temperature facilitates the reaction.

Why do the bees produce honey?
The society of the bees this compound one for, it reigns, worker and drones.
Those in charge of producing the honey are the workers.
They manufacture it with the nectar of the flowers and a special saliva that it segregates the insect. The honey for that it is the food that you/they use to feed the larvas during its first periods of life, take place they also take it the mature bees in the winter times.
People also take advantage of this product, since the honey is a very energy food and it contains many vitamins.

Why are there spiders of water they float?
To these spiders they are called hidrómetras, since they live and they feed of microscopic beings that it contains in the water.
They have a long and thin body and some very fine paws.
In the paws they have an oily substance that waterproofs them, that is to say that it allows you to stay dry.
This substance, independently of the superficial tension of the water, it acts like a membrane of sustentation, what not allows him alone to stay to it floats but rather they can slip swiftly on the surface of the water.
When there is something that gets scared them they slip quickly on the water to the aquatic skier's way.

Why insecticides are they used to kill the flies?
The flies are a little some insects pigs, because in the means in that you/they move they are muck-collectors, dirt, etc.
The man the combat to avoid unhealthy infections and the best means that he/she has been to combat them is the insecticide.
The insecticides are some chemical substances that don't affect superior animals, but that they eliminate the flies attacking mainly their breathing system.
They also threw insecticides in the cultivations to eliminate the insects that eat up the plants, but today in day less polluting methods they are used, since he/she was discovered that it was a serious danger of contamination for the vegetable foods.

Why do the cars need oil for their operation?
Besides the gasoline, the cars need oil for their correct operation.
The motor produces some explosions that originate gases, the force of these gases it impels a piece called piston.
The piston transmits the force until ending up being applied to the turn of the wheels.
The oil is necessary because, these pushes produce frictions and increases of temperature that could damage the pieces of the motor.
Mineral oil is used that lubricates them when introducing it among the pieces, allowing that they slip easily and this way to conserve them under good conditions.

Why do the cats always fall of foot?
The cats are very agile and they can be turned in the air, while they fall, trying that their point of graveness is centered.

Why do we dream?
The dream is a process for which the mind stays active, reviewing events that happened during the day, mixing them with memories of the past and creating new images. There are several stages in the dream. We have to sleep so that we can rest and we can recover of the waste of the day.

Why does it leave a scab on the wounds?
When you injure the skin, the cells sanguine called badges get ready to intervene, forming a clot that prevents that more blood flows to the exterior. This clot is formed by the badges and a called fibrous material Fibrina. Conform to it hardens the clot, he/she goes being formed the scab, of dark reddish aspect, which helps to maintain the far away germs and he/she offers to the skin the opportunity to go being regenerated under her.

Why do we sneeze?
The sneeze is the form that has the body of eliminating any irritation in the nose. When something bothersome in the nose a part of the brain receives the message and he/she sends an answer message to all the muscles that have to do with the sneeze: the abdominal muscles, the muscles of the chest, the diaphragm, the vocal chords, the muscles of the lids, etc.

Why the same hour is not in all the countries?
The broken Earth in their same axis. The time of rotation of the Earth has been divided in 24 intervals called hours. To fix when it begins and the rotation concludes he/she takes into account the moment in that the sunbeams fall perpendicularly on the Earth (there is hardly shade) and to this moment he/she is denominated noon or 12 of the morning. As the sunbeams they don't fall perpendicularly at the same time on all the countries, there are different schedules.

Why is the sky blue during the day?
The white light is made up of several colors. When penetrating the solar light in the terrestrial atmosphere he/she spreads adopting the blue color.

Why do we shiver when it is cold?
When it lowers the temperature, our body it begins to tremble with the purpose of generating caloric energy, mobilizing the muscles of the body.

Why do we feel the air if we cannot see it?
The air is formed by gases, among them the oxygen and the nitrogen. We don't see them because the molecules walk very separate some of other what allows the step of the light, but if we can feel it when it hits our face.

Why does the echo exist?
The sound is transmitted by means of waves. If these waves collide with something, they bounce toward the original place, to that which is denominated echo.
