Zebra afraid to fly over Assad

Zebra afraid to fly over Assad


Some mistakenly believe that the zebra has flogged "scheme" to hide from the eyes of the lion king of the jungle in the African bush, but science says that these lines protected by the first of his enemy, a fly "Altawon" Assad eat donkey one but fly descend harm each herd of donkeys.



The researchers found in animal science, one Hungarian and one Swedish ass scheme is not afraid of Assad as his fear of fly "Altawon" that live on the absorption of the blood of humans and animals.



The researchers emphasize that the black and white lines on the zebra skin works on the polarization of the light vertically, which fly away Altawon pounce on the bodies of animals that reflect their skins light horizontally.



Referred to as Female flies Altawon not lay eggs unless swallowed large amounts of blood and cause the fly in causing great suffering in rights Oalehioan when absorb Dmehma but it does not cause death or serious illness.


Noteworthy that the length of the fly "Altawon" that frighten zebra in some cases up to 3 centimeters.



Hallelujah .. Hallelujah .. Hallelujah

Your outlook on life determines your body's immunity

Your outlook on life determines your body's immunity
نظرتك الحياة تحدد مناعة جسمكA new U.S. research confirms that those who enjoyA positive outlook towards life, enjoy better health, ....
Search revealedNew American that the quality of a human look at things around him determine the immune systemTo his body, where the study says positive outlook in life have a beneficial effect onHealth and enhance the body's immune system, and this disclosure may have a significant impact onTreatment methods.
The research revealedInter-University "Kentucky" and "Louisville" that feeling optimistic about the futureMay lead to feeling better, in fact, and that optimism is good for health as it would enhance theThe body's ability to fight infection.
The resultsThe research, published in the journal "Psychology" that the strength of the body's immune responseRise more optimistic, and the response is slow between pessimists.
In a studyPrecedent shows that optimism is good for health and may prevent, to a large extent, the chances ofCardiac stroke or even death.
Scientific research confirms that optimism personThe future is controlled through a small part in the introduction to the center of the brain.
And showedStudy to that region, which is located in the rear behind the eyes, react when inspirePerson positive thoughts about what might happen in the future.
Also, scientists sayThe optimists are less likely than pessimists to depression or asylumSmoking, as they seem younger, and obtain a larger share of education and receivingImproved income, as they are more religious, according to the study published in the journal"American Heart Association."
PositionsFrom the Quran and Sunnah
ThePonder the verses of the Koran finds it full of optimism and even learned how to look atLife a positive outlook, there is no place for despair in the life of the believer ... To the extent that the KoranHe who despairs of the mercy of God infidel! Allah says: (do not despair of God's Spirit that he did notDespairs of the Spirit of God, except the people who disbelieve)[Yusuf: 87].
Even in the most difficultAttitudes suffered by the Prophet, peace be upon him find joy God's mercyAnd not sorrow, Allah says: (TheNarrated by who disbelieved the second two as they are in the caveHe says to his companion not grieve that God is with us)[Repentance: 40]
Therefore God has addressed the believers not to grieve, whatever the circumstancesHe said: (slacken not inGrieve, you incline if you are believers)[Al-Imran: 139] ..
The KoranConsidered all of the despair of the mercy of God lost,! Allah says:
(And who despairs of the mercy of his Lord exceptAstray) [stone: 56].
Look with me to this divine call to those whoPlagued disobedience but and ladle in trespasses and sins, God says:
(My slaves who have transgressedThemselves do not despair of the mercy of God that GodForgives all sins He is the Forgiving, the Merciful)[Cliques: 53]
And focused me on these words (do not despair) ... (NotGrieve) ... (NotDespair) ...All orders directly from God for His slaves to correct their visionTo life to be a positive outlook.
WhereasUninsured despair of the mercy of God, the Almighty says:
(And those who disbelieve the revelations of Allah and his meeting with thoseDespaired of My mercy for them a painful torment)[Spider: 23].
Therefore, we find the impact of religion on mental and physical health of the human beingInsured, the more confidence was greater believer in God whenever enjoy better health and stronger immune.

Chemistry of love

Chemistry of love
Became scientific dogma that love chemical process replaced the human brain. And now all scientific theories interacting in the global scene, agree that the human brain is the User responsible first and foremost about love, and thus became the introduction of the proverb loving heart, such as scientific error, for the time being.Did not stop at this point, but became love scientifically theme can be seen and analyzed and interpreted, and there is a controlled and directed. Thus science Answers feet clear and explicit, on the subject of light through human history surrounded much of a mystery.He said veterans that love is blind, because it can collect a man ugly woman gorgeous, or even destitute girl from class kings, without knowing why, but scientists at the University of London ended up in their research that the human when loves disrupted parts brain controlling the thinking The active regions responsible for emotions.While speaking ancient disease love that infects lovers go crazy sometimes and not cured him owner only seeing beloved or hall, without providing convincing explanation for it, could scientists nerves of the brain to confirm that there Gdtan in the head two key role in the sense of connectedness, two الغدتان Nevsihama which are pushing to addiction. And falling in love increases the secretion of this gland.While the ancients said of prestige beauty, comment on these strange thrill that is shaking the human body while reflecting beautiful face, scientists found that the flow of adrenaline in the body is responsible for facial redness, and increased heart rate, sweating body.While speaking veterans for the joys of love and sorrow, and two originals that near beloved and beyond, without realizing this disparity in a sense, make sure the scientists today that behind that sense of a big job in the nervous system, and then the impact on body Habib and his mind. The brain can continual secretion of excessive amounts of hormones that provide the body with the necessary activity and warmth, and in contrast, go beloved leads to a lack of these hormones and then a sense of depression and emptiness.While veterans believe that love is something aware of hearts, tongue can not express it, scientists revealed that the brain is the one who allows love. And that love does not happen suddenly, but after the approval of the brain, and then celebrates his arrival hormonal system. These biochemical processes can be observed and diagnosed.Finally we can say while he was replaced love of metaphysics, has become a laboratory par excellence.
1 - pathways loveWhile scholars agree that love brain phenomenon essentially they differed in determining Msaleckh, I mean organic channels routes to reach the brain, and in this context we can talk about three theories:Love sniffLove givenLove hearing
1-1 love sniff:
1-1-1 to know the sense of smell:
What a nice smell!If unconscious express them repeatedly without being aware that access to it, was over the course of complex organic flour. All we know that أنفنا was able to tell us the type of smell, Fberna بلساننا this sense. But the biology of the brain says something else.True, we smell Bonova, specifically Section top of the nose, if we look at the wall nose procedure, we find the three pieces bone-COATED snotty override each other and called spouses, they share in the process of heating the air as it passes the nose, if we look at the above consort upper seen region olfactory. Distributed olfactory nerve fibers after pass the ceiling of the nose through a perforated plate Kagharbal sieve plate.Is to distinguish between odors by specialized cells called receptors. It cells or parts of cells, and function to receive information. Work can be likened to the work of small antennas are very sensitive.
Send those cells information through nerves to Alheibutalamos, which is responsible for hunger, thirst, and sexual feelings and emotions. There stationed warehouse smells, more valuable form of olfactory memory.
If we recognize that smell opens the appetite appetite for something or to ignore them, by their nature, how lead us to fall in love?
1.1.2 love the taste of musk:To smell a distinct presence in the Arab love poetry, by insisting on the beloved Tdmokht perfume, and wafted his goodness, and enumerated types of perfumes and aromatic substances, and the magical effect that leaving him in self-lover:
And Ftanh eyes fancy fighting if Nfan elders aromas of ShebaThe متنبي House, which means that this charming woman, eyes Alvatantin, and love the killer, can be traced back to Sheikh youth if Nfanh aromatic Broaúhaa.
To love the smell, and the darling distinctive fragrance, not attended by, but also in their absence, just Kmlameh addressed:
Insane longing Without that smell you're visiting in the winds of longing mind
And the meaning of home, were it not for the smell beloved committees longing after them. And such a house say Abbas ibn Ahnaf:
هاجت me wind نفح smell revived my bones and هاجت along memorial
As crazy Leila finds smell in clothes worn by:
What touched my side earth but I have mentioned and only found its fragrance in her clothes
What kind that smell? Answers Bashar as the scent of musk and basil:
Basil scent reminds me that if you do not perfumed agreed musk fragrance
Through this evidence shows that the smell of Habib did not effect my presence only, but with a strong memory.Relationship olfactory memory which talked about the Arab poet. Recently endorsed by science, you can not smell unless summoned the smell in your memory I. .. Or in other words, the memory active smell ..
The history retains some Almruyat that prove the relationship between smell and love, including what he had done Mc_lemh liar when he was able to يستميل "سجاح", his rival in the claim of prophecy, and persuaded her to marry him so riding is his claim, and after that theme tent made to negotiate بعبق incense Arab.
1.1.3 love the taste of race:Race acidic liquid is colorless, with a foul odor, contains some mental acids and minerals, and emerges through the skin through the sweat glands. It is a small tubular glands located within and below the surface of the skin, and the race goes through openings, which ends this pipe at the surface of the skin.
Secreted race under the influence of sympathetic autonomic nervous system through the neurotransmitter Alosatikulan Acetycholine. This consists of sweat glands secreted part, produces sweat, and a tubular part, reflects the skin to open on the surface of the skin.
As for the relationship love the smell of sweat, some research has shown that the varieties of scientific women are attracted to strong odors, especially in periods of pregnancy.
In another study conducted by U.S. scientists from the University of Chicago and published in the journal-Nature Genetics, confirmed that the varieties of women are attracted to odors similar to the smell of their fathers.
The tests were conducted on forty-nine unmarried women were asked to smell the clothes worn by men, and it appeared that they tend to smell like the smell of their fathers.The researchers explained this choice to go towards men with the experimenter's immune system, already tested by the father. But the researchers noted that women tend also to men who have almost a slight smell of the father, to ensure that women greater variation in the genes next offspring.
 
1.1.4 Love BelvirmonIt may seem impossible to many loving convince them that they fell lying love noses, not because they have been affected with a good smell, but because of minute particles, odorless, made them run behind Habibathm.
The theory can love Belvirmon, to prove them noses involvement in grief, albeit topic has not yet been decided.
How love Belvirmon?Owners say this theory that man is like mammals and insects secreted his body chemicals, can be of interest to others of the opposite sex, and move their desires, by employing the sense of smell and specifically a tiny organ in the mucus that coats the upper part of the nasal cavity. Pick this User those materials and then sends them to Alheipittalamos for direct contact, the brain Ahsasatna center. There is research on the substance of the message, and if you are not there are contraindications called brain signals approval باستنفار his hormonal system.
Organic material called mobile between the two pheromones Les Phéromones a chemical secreted by the human body through his reproductive system and his armpits and nipples, and lashes his head. Substances that do not smell it, but the brain can read and comment on the content Bslokat approval or rejection. Everyone has Verumonath to own, that determine the composition of organic and social affiliation.Due attention to the subject of the pheromone to 1911 with John Henry Faber research when deliberately to put female butterflies in a cage, while males put a 5 km. Moments later found males had approached the cage. He therefore concluded that there is a chemical sent female to lure male. Was this article is for the pheromone.In 1959, scientists put Calson Osber term pheromone, a complex of جذرين Igriqian: hormon exciting and transfer pberain. The situation has definition Alltala:
Pheromones secreted material individuals received by other members of the same species, to make a specific response, or biological or shift position.
 
The pheromones essential communication tools between insects and animals, Vboisttha can choose her sexual partner, and co-existence between them. Scientists have taken an intriguing research in the human body and brain to reach similar responses by pheromones, Faqamt many experiences in the field confirmed that the man is no exception animal in the recruitment of his nose while choosing their partner.
In 1978, Professor Kirk Smith Kirk Smith of the University of Birmingham to study a sample of 840 women, Jmahen in the hall by some seats. And asked them to choose one Mekda. The result was that 80% of them chose a particular seat. Because he was Mdhuna with Alondristanol material which Pheromones Men.I love theory led scientific research Belvirmon to embrace business, and found it a commercially attractive theme, and highly profitable, and the result was that the perfume was manufactured supported Belviromunat.
1.1.5 wonderful fragrance to bring beloved:
Cents 2000 magazine published "physiologic End" the results of a study of 36 women. 74% of those who wear the normal Atrhen mixed Belviromunat noticed a significant increase in sexual activity, compared with 23% of women who gave birth Atrhen private mixed material is impressive.
Said one of the posts she had lived usually sexual intercourse and one week with her husband, but it increased to four times during the probationary periodAnd supervising the search said Norma McCoy, a professor of psychology at the University of Francisco, the smell can not be captured, and is not aware of the man or woman of their existence, but they are very strong. She added that this chemical apparently active man's sexual desire.
So, it, in the opinion of these companies is very simple, you object like Bonevk, So what you only wear perfume pheromone perfume for women rushing you. Says one of the ads:
This fragrance Femina Belviromunat, a new version include humanitarian فيرومونات fixed scientifically, to arouse men. Just as happens to the animals that employ smell to raise partner, human responds to فيرومونات, and then you are able to be greatly multiplier your chances to attract you like men.
This fragrance composed mainly of natural pheromone laced with specific oils to create a smell that will attract you without minds of men. You will find yourself with this fragrance is surrounded by men smiles and the look in their eyes.
Says another ad men prompt:
 
Current evolution was able to disarm the men the ability to secrete the necessary quantities of pheromones that will raise women. The little pot that is secreted day be destroyed.This work of scientists to identify and isolate and reproduce this installation wonderful Elvirmona and strong.If you used a little bit, the results will be impressive. You'll find yourself suddenly surrounded by women and they Athawkn you.
Such ads mouth saliva looking for love, or for fun cheap crowded Internet to sell this wonderful fragrance in vials of 29 ml and 100 ml Bothmna up to U.S. $ 60. Just imagine how much will the profits of these companies, especially since they beat the chord in the human psyche.
It is worth mentioning to to exploit Tzerah love sniff for commercial purposes, created two contradictory trends in scientific research, the direction of the first excited her and defended them, taking advantage of corporate profits. Foremost among these, Dr. James Kuhl, who devoted his research and writings to defend this theory.On the other end we find totally researchers refusing to such exploitation of scientific, Dr. Alan Hirsch is one of the defenders on the impact of the sense of smell in sexual choices, excludes never be so fragrance any income. But defiant went to that request from one of the manufacturers of perfume that the experience of love for one of its products, but declined to then adds, "and you that Tstntjoa".
While gold Dr. Ivan Rodriguez to question originally in theoretical ab, unlikely to be of Pheromones effect in love in humans, for the simple reason that the man is not an animal, but is an object conditional other factors overlapping says: "We must not have illusions that pheromones humanitarian sold in vials volume of 100 mL days will enable us to raise women. largely when the animals and insects in particular. As we Vnozv important information in addition to those that come to us through the nose, when looking for a life partner, for example. "

1-2 love given:
 
According to a recent study conducted by researchers at the Massachusetts Institute of Technology in the United States to see a beautiful woman raises a sense of joy in the man's brain is similar to the feeling, which feels hungry when dealing with a delicious meal or a patient's pill abuse.The results of the study, published in the journal Neuron that the beauty of a woman in a man's brain affects the normal level directly and not on the level of mental and intellectual high.Dan Arieli said co-author of the study: "The beauty of a woman is similar in effect to effect pill for the patient." Have been used in this study images of women in the mid-twenties age varying degrees of gravity, and measured the impact of receiving men involved in the study to eighty image of faces, has demonstrated the study numerically this effect nearly a delicious meal for a hungry person or influence medication for patients suffering from a condition painful.Said Dr. Hans Breter participant in the study that has not happened before to highlight the impact of beauty on primary brain circuits so clear if the results of the study confirm that there is validity to the arguments to the effect that beauty is not only a product of society's values.
Back of this study was to confirm the argument that the prestige beauty including means of influence of the visual field in our emotional choices. The eye here captures the image of women, her face, or shape and created by, or any part of an exciting, and then sends the message to the brain that has to decide its final position, either admiration or hate him. But how is this process organically?Can distinguish between four stages:
- Watch face sexy
 
- Activity visual area of ​​the brain (occipital lobe).- Analysis of Facial markings and comparable to those that have been stored- Make an affirmative or negative position.
Vmahi standards الني help brain generally impressive without the other?

Beauty values:From a sociological point of view, the cultural dimension of a society is echoed in all individuals who live within it. Nor draws beauty as a cultural value for this rule. Therefore do not be surprised to find metrics ugliness in a certain human benchmarks are beauty when another group, and even within the same group known metrics beauty changes from generation to generation and from a historical era to another, they were obesity required in aesthetic Arab women of old, as an indication of the status of social What, while thinness means that women get tired a lot, but today it became obesity is not grainy, and the world is under the authority of one form provided by fashion houses, and embodies singers video clip.
Overall, the beauty of cosmetic scientists means consistency between the components of the face, following the law of thirds, or quintiles law.
Law Thirds:Face is divided into three equal horizontal zones.
First Zone:From the hairline to the horizontal line passing eyebrows.
Region II:Of the former line to the horizontal line that passes down the nostrils.
Region III:Of the former line to the end of the chin.
If the three regions equally divided the face is nice .. If disrupted distances, the face loses some of its beauty.

Law Fifths:
 
And the standard distances between equal parties face vertically from the right ear to the left, as shown in the drawing pro.


"No woman is beautiful"From the perspective does not seem realistic that view intact, but cosmetic medicine bump propaganda slogan, "but no woman can not show her femininity and beauty." Here crux.It is an invitation to the beauty industry, which has become one of the most important industries in the medical world, building on the form provided by supermodels, and the film industry.

Subconscious singles:
Individual psychology goes that the man loves only a picture of his mother, who kept in containers since childhood. It attracted in terms of not knowing to those features that are no longer remembered but reserved in his mind. Freud says: "We do not meet only with what is in our consciousness." He adds Christian David, "each and every one of us carries within nostalgic ideal first love, motherly love, and desire to reproduce remains alive in us."
While John George went Lemerre we meet with dream. The node narcissism is that we went in our emotional choices. We are looking for another approve what we think, what we want to be. We are looking for a mirror that reflects the positive image that Nkunha for ourselves. Ideal is the basis of love. No emotional relationship without giving the value of the partner.

1-3 love hearing
The ear loves sometimes by eyePerhaps Bashar ibn Burd said this poetic part because he was blind, he can not love without his permission, but he expresses a scientific fact that the blind a sense of hearing than those of sighted. Also is a not next fact that ear may Tsagtna in love, as we have seen with the nose and eyes. How so?
When we hear a voice, we can respond directly Do you know this sound.
 
This rule tells us auditory lobe which has a natural ability to learn vocal species, including discrimination, the right side of the brain, then search for the name of His voice and his address in the left side.
Just as the brain relaxes the odors without the other, and are attracted to faces and not others, it may prefer sounds specific, so often Manicol that this girl beautiful voice, or for this boy voice Rgema, not only because it was well received in the brain through the memory retains voices particular characteristic. Thus men are attracted to women, and women to men of the nature to change my voice.



2 love hormones


Presented by:Proved the nerves of the brain that scientists falling in love requires the brain to secrete hormones reflect the happy moment. Thus active mind, and hide the body, and facial blush, sweating hands, and heart beat. This festival deserves the title of hormonal love hormones.

Dopamine: pleasure hormone or hormone good senseThis hormone secreted by the brain in moderate amounts and fixed in situ in order to preserve the mental balance within the nervous system. Because it is responsible for transmitting signals relating to feel comfortable and elation, whether it is after eating a delicious meal, or win ..
The falling in love pushes the brain to produce excessive amounts of dopamine activate receptors in the case, feels beloved is in the hands of the beloved, actively irresistible, and pleasure, and only due to this strange magic called dopamine.
Love Addiction:The scientists found that the hormone dopamine in excessive quantities, by external stimuli such as smoking and stimulants, eating, drugs .. May lead to addiction. Drugs, for example, mobilize in record time all receptors, thereby creating a negative effect on brain cells, which destroyed some dopamine receptor, which may lead to spoil the mood of the addict.
On the other hand revealed researchers at the Brookhaven National Laboratory in New York that the sense of dopamine centers in people hull be less, this pushes them to binge eating to feel complacent. U.S. scientists revealed that the glands, which leads to drug addiction are the same glands that are active during the falling in love. Then love may become addictive. There is no doubt that dopamine is responsible for this.

Serotonin:
Broker Kamiaúa depends upon the brain to regulate human behavior. The if Simmer amount to increase or decrease the impact on the individual's life, and personal conduct. Faisab concerned and feel depressed if the lack of, and extroversion tends to overload, which may exceed the social controls, if produced in large quantities.
The falling in love increases the secretion of the hormone necessary to achieve activity, especially in women who have no less likely to have. And thus, help to avoid depression, that Tlazemhen and lead them in many cases to fall prey to depression.

Adrenaline and noradrenaline:While surprised by the position of what occurs excitability of the sympathetic nervous system which activates the two recipients of the thyroid gland. Kinetic adrenaline activates receptors alpha and Bita 1 and Bita 2, either noradrenaline Feinst only Alpha and Bita 1. These receptors are found in blood vessels. This is often accompanied by the secretion of these hormones redder in the face, and accelerated heartbeat, sweating body.This situation often accompany lovers, either when you see the beloved, or hear his name, or meet him in an intimate encounter.

Oxytocin:Love hormone. Or hormone psychological and physical comfort, and the feeling of warmth and security. While falling in love increasing amounts excreted, and has a range during ejaculation.The scientists also found that behind the sense of happiness of compatible couples, because those intimate times spent by the man with his wife contribute to activation Alvasubresen receptors.It With a bilateral dopamine pleasure to lovers.
 
Alvasubresen:
Sincerity hormone. Or choose a partner hormone. Research has shown the brains of mice to those that arise in the fields and known to choose one partner, characterized by the presence of high levels of Alvasubresen stimulation centers in their brains. The mice mountains multi-partner, there has a future. On the other hand reached the world Stephen Phelps at the Institute Armory to the presence of a large diversity in the distribution of vasopressin receptor cells in voles, which means there are differences in the social behavior of the mouse to another. It is the same thing discovered by Dr. Larry Young in humans, and then said: "We may be able, for example, the study of genetic sequences or sequence iPS cells to classify people according to their genes and linked to the degree of loyalty they have." In 1999 Dr. Young led the team took receptor gene in vole and put it in a normal mouse, and the result was a rat more relevant to Bashrike.

Third: organic sedimentary rocks Organic sedimentary rocks:Consists of this type of sedimentary rocks of the remains of living organisms, whether animal or vegetable, and sometimes called sedimentary rocks biochemical Biochemical sedimentary rocks, the most important examples limestone reefs Reefallimestone consisting of cohesion remains coral reefs dead saturated calcium carbonate extracted from sea water, and contribute to these metals in the cohesion of residues reefs, stone chalk Chalk which consists of cohesion remains of microscopic animal and vegetable, and stone coal Coal, which consists of decomposing plants after burying roasted and exposed to the impact of global temperature and pressure (Mohammed Ghani Musharraf, 2002).

Drink water and you're in front of a computer


Logo must call of protect ourselves from the dangers of electronic devices ...
Reached a recent medical study conducted by public health consultant and Preventive Medicine at the Ministry of Health of Egypt that eating two liters of water a day helps to avoid the risk of infection electronic devices ...
The study revealed that the use of electronic devices Kalkmpiotr, microwave, mobile phone and exposure to them for long periods of time causes many risks least injured mental stress her employer and mental, as well as that issued by radiation may affect the blood,
And lead with the length of time of exposure to Haely anemia and opacity of the eye and infertility. And may even be somewhat cancerous tumors ...


The study warned that children and young people are more susceptible to these risks, which could affect their development,
And advised not to Azidadd hours of exposure to computer for two hours a day.
