Benefits and Uses of Human Pheromones

Benefits and Uses of Human Pheromones

human pheromones is essential sbagai natural communication media produced many organisms that turned out to be useful to humans. Even proven that the media is the location of growth and development of love and affection between people.

There are times when we often ask, why the ant when the ant often meet fellow first kiss? And, what is the purpose pleky, our mutt, when in a particular location will be urinating on the area? This is not a form of mere fad, right?

Basically, ants and pleky not just fun to do the activity. All of that is a form of interspecies communication of their kind. Ants communicate in preaching the variety of things, from telling the location of food, there is a danger, to detect members of the group. Whereas in the case pleky, he marks his territory to other dogs know that the area belongs to him. Minimum reported that pleky was here!

Well, all these activities can be done via a chemical compound called pheromones (pheromones, from the Greek word meaning pherein bring or carry). In the Encyclopaedia Britannica, pheromone is defined as a chemical compound that is secreted (or produced by certain glands) in an organism in a very small quantity, then cause a specific response of other organisms of the same species. Of course that means, pheromones given by an ant must be understood only other ants, not beetles, bees, or butterflies. Likewise with the pheromone produced by the Pleky urine, can only be smelled by his friends, his dog.

Pheromones are many found in various species of insects, vertebrates, as well as in several types of mushrooms, fungi, and algae. Real form of the pheromone is a certain smell that is usually found in vertebrate animal urine, saliva, insects, or pollen produced by organisms of the pathogens and friends.

Environmentally friendly

Once relies on pheromones as a medium of communication between certain organisms, making the chemists (who investigate the origins of their chemical compounds) and many biologists (which examines each organism) are curious and amazed. Tell me, who is not impressed. Without having to talk, give the code signals, writing, and reading the message, the organism is able to communicate. Only through smells or scents are produced pheromone.

The uniqueness of this pheromone latter fact can be used for the benefit of man. Precisely, when known that insect pheromones are also used in marking their partners to make further breeding. Thus, female insects, in certain periods, spreading insect pheromone to males, as a sign could be the start of mating season. Maybe if in our world, such as casting spell or giving okay sign, for the next ready-Female and dipacari, yes.

Through the phenomenon of pheromones as sexual attraction, the experts then make a concoction of synthetic pheromones used to eradicate insect pests. Fun, these ingredients are not killed, but limit the insect population. So the male insects fed with synthetic pheromones that produce similar odor from the female pheromone.

why women must be wearing jilbab

why women must be wearing jilbab
The term jilbab or jilbaab (Arabic جلباب) is the plural of the word jilaabah which refers to any long and loose-fit coat or garment worn by some Muslim women. They believe that this definition of jilbab fulfills the Quranic demand for a Hijab. Jilbab or Jilaabah is also known as Jubbah or Manteau (which is the French word for coat or mantle).

The modern jilbāb covers the entire body, except for hands, feet, face, and head. The head is then covered by a scarf or wrap (khimar). Some women will also cover the hands, feet, and face (niqab).

In Indonesia, the word jilbab is used for a headscarf rather than a long baggy overgarment (Geertz).

The plural of jilbāb, jalabib, is found in the Qur'an, verse 33:59 (Surah Al-Ahzab). The verse in transliterated Arabic and the popular translation of Yusuf Ali goes:

Ya ayyuha an-Nabiyy qul li azwajika wa banatika wa nisa al-mu'minin yudnina alayhinna min jalabib hinna; dhalika adna an yu'rafna fa laa yu'dhayn. Wa kana Allahu Ghafur Rahim

O Prophet! Tell thy wives and daughters, and the believing women, that they should cast their [jalabib] (Jilbabs) over their persons (when abroad): that is most convenient, that they should be known (as such) and not molested. And Allah is Oft-Forgiving, Most Merciful.

Whereas Yusuf Ali is not an accredited scholar of Qur'anic exegesis, Hadith (oral traditions of the Prophet Muhammad later recorded by contemporaries of his companions), or in any other religious field by any Islamic standard (by Islamic scholars of institutions such as Al-Azhar of Egypt, Dar ul-Uloom of Pakistan and India, Islamic University of Saudi-Arabia, etc), the translation of the Qur'an entitled Interpretation of the Meanings of the Noble Qur'an in the English Language by Dr. Muhammad Muhsin Khan and Dr. Muhammad Taqiuddin Al-Hilali is a better representation of Sunni thought as its meanings are taken from the books considered most authentic and accepted by all Sunnis, such as Tafsir Al-Tabari, Al-Qurtubi, Tafsir Ibn Kathir, and from the sound books of Hadith, Sahih Bukhari and Sahih Muslim. It is certified to this extent by Shaykh 'Abdul 'Aziz bin 'Abdullah bin Baz and Shaykh Umar Muhammad Fullata, two scholars of renown throughout the Sunni world during the latter half of the twentieth century who also represent two of the most prominent institutions of Sunni Islamic scholarship, Dar ul-Ifta in Riyadh, Saudi-Arabia and Islamic University of Al-Madinah Al-Munawwarah in Medina, Saudi-Arabia.

Its translation is as follows:

O Prophet! Tell your wives and your daughters and the women of the believers to draw their cloaks (jalabib or veils) all over their bodies (i.e. screen themselves completely except the eyes or one eye to see the way). That will be better, that they should be known (as free respectable women) so as not to be annoyed. And Allah is Ever Oft-Forgiving, Most Merciful.

(V.33:59) "They should cover (draw their veils (jalabib) over) their bodies, faces, necks and bosoms, etc., not to reveal their adornment."

This translation, "screen themselves completely except the eyes or one eye to see the way" is specifically from: Tafsir Al-Tabari, Vol. 22, page 33 and Tafsir Ibn Kathir, Vol. 6, page 471. This is also cited in the most senior tafsir (commentary of the Qur'an) of all, Tafsir Ibn Abbas, page 407, the edition published by Darul Fikr of Beirut, Lebanon. Ibn Abbas has the status of Sahaba, or companion of the Prophet.

There are hadith which serve as commentary on the above verse of the Qur'an (33:59) which mention the jilbab, such as the following:

Narrated Safiyah bint Shaibah: 'Aisha used to say: "When (the Verse): "They should draw their jalabib over their necks and bosoms," was revealed, (the ladies) cut their waist sheets at the edges and covered their faces with the cut pieces." (Sahih Bukhari, Volume 6, Book 60, Number #282)

Another hadith mentioning the jilbab follows:

Narrated Umm Atiyya: We were ordered to bring out our menstruating women and screened women to the religious gatherings and invocation of the Muslims on the two Eid festivals. These menstruating women were to keep away from the musalla. A woman asked, "O Messenger of Allah! What about one who does not have a jilbab?". He said, "Let her borrow the jilbab of her companion". (Sahih Bukhari, Book 8, #347)
