모노누클레오시스 바이러스가 2008년에 페더러의 기량을 하락시켰다

로저 페더러(Roger Federer)는 전문가와 전·현역 선수들에 의해 역사상 최고의 선수로 꼽힌다. 2009년 윔블던에서 우승함으로써 샘프라스(Pete Sampras)의 기록인 그랜드슬램 타이틀 14개를 넘어 역대 남자선수 중 가장 많은 타이틀을 획득한 선수가 되었으며, 2010년 호주 오픈에서 우승함으로써 그 기록을 16개로 늘렸다. 약점을 찾을 수 없는 완벽한 테니스로 해마다 2~3개씩 그랜드슬램 타이틀을 차지하던 페더러는 2008년 들어 극도의 부진을 보였다. 호주 오픈 4강전에서 조코비치(Novac Djokovic)에게 3대 0으로 지고, 프랑스 오픈에선 나달(Rafael Nadal)에게 6-0으로 세트를 내주는 굴욕을 겪기도 했다. 결국 그는 윔블던에서마저 나달에게 패하며 237주 동안 지켜오던 세계랭킹 1위를 빼앗겼다. 그 해 페더러에게 도대체 무슨 일이 생겼던 걸까?

EB바이러스 감염에서 중요한 것은 바로 B림프구

그 해 초부터 고열과 무기력증에 시달린 페더러가 병원을 찾은 건 호주 오픈이 끝난 뒤였다. 그가 받은 진단은 ‘Epstein-Barr virus (EB바이러스)에 의한 전염단핵구증(infectious mononucleosis).’ 이 병을 알기 위해 잠깐 혈액에 대해 알아보기로 하자.
인간의 혈액은 액체 성분인 혈장(plasma)과 세포 성분인 혈구로 이루어져 있다. 혈장에는 단백질과 지질, 전해질 등이 있으며, 우리 몸을 보호하는 항체도 혈장에 있는 단백질의 하나다. 혈구 대부분은 산소를 운반하는 적혈구고, 백혈구혈소판이 1% 내외를 차지한다. 혈소판은 혈액응고에 관여하며, 백혈구는 다른 병원균의 침입에 맞서 우리 몸을 보호하는 군대 같은 조직이다. 군대가 모자에 그려진 막대기 숫자로 계급을 구분하는 것처럼, 백혈구도 세포 안에 과립이 있느냐 없느냐에 따라 과립구와 비과립구로 나뉜다. 과립구의 대표인 호중구(neutrophil)가 백혈구의 54~62%를 차지하며, 세균 등의 병원체를 잡아먹어 세균이 퍼지지 않게 해준다.
비과립구의 대표인 림프구(lymphocyte)는 25~45% 정도며, 면역반응을 관장한다. 우리가 백신을 맞는 것도 알고 보면 림프구한테 그 병원체를 기억해 달라고 부탁하는 것인데, EB바이러스 감염에서 중요한 것은 바로 림프구, 그중에서도 항체를 만드는 B 림프구(B 세포)다.

EB바이러스는 침을 통해 전파된다

EB바이러스는 타액분비, 즉 침을 통해 전파된다. 이 대목에서 말을 할 때 유난히 침을 튀기는 주위 사람이 떠오를 것이다. 하지만 침이 튄 게 내 입에 들어가 EB바이러스가 전파될 확률은 지극히 낮다. EB바이러스는 보다 친밀한 관계, 즉 감염된 성인이 키스해줄 때 옮겨진다. 그렇게 들어온 바이러스는 입 안의 여러 곳을 감염시키다 편도선으로 가서 B 세포와 접촉하는데, 평소에는 안 그러던 B 세포가 EB바이러스만 만나면 급히 흥분을 해버린다. 세균에 대한 항체를 만들어야 할 B 세포가 우리 몸에 대한 항체를 만드는 것. 그것도 숫자가 엄청나게 늘어난 채로 말이다.
EB바이러스는 주로 침을 통해 전파된다(왼쪽). 헤르페스 바이러스과 중 하나인 EB바이러스의 10만배 확대사진(오른쪽)
그걸 놔두자니 심각한 상태가 벌어질 것 같아 우리 몸이 나름의 대응을 하는데, 그게 바로 헌병대에 해당하는 T 림프구(T 세포)를 출동시키는 것이다. 헌병대답게 T 세포는 바이러스에 감염된 B 세포를 마구 제거하며, EB바이러스로 인한 증상은 대부분 이때 나타난다. EB바이러스 감염 때 혈액에는 이상하게 생긴 림프구가 많이 보이는데, 그게 바로 급히 동원된 T 세포다. 건강한 사람이라면 이런 과정들을 통해 EB바이러스가 제거되나, 일부 B세포는 여전히 이 바이러스를 갖고 있고, 이건 평생 지속된다. 면역이 약한 사람에게선 B 세포의 증식이 계속되어 암이 생길 수도 있는데, 버킷림프종(Burkitt's lymphoma)은 그 한 예다.

잘 사는 선진국에서는 전염단핵구증을 자주 볼 수 있다

인체의 현병대와 같은 역할을 수행하는 T림프군. 전자현미경 9,560배 확대사진
EB바이러스 감염은 전 세계에서 발생한다. 성인의 90%가 이 바이러스에 대한 항체를 가질 만큼 흔한데, 어린아이들에서 가장 흔하지만, 다행히도 이때는 대부분 무증상이거나 가벼운 인두염으로만 나타난다. 그다음으로 흔한 그룹은 역시 키스를 많이 하는 청소년과 젊은 성인으로, 이들의 75%가 전염단핵구증 양상을 보인다. 위생상태가 좋지 않은 나라에서는 EB바이러스가 대개 어린 나이의 소아에 감염되는 반면 잘사는 나라들에선 성인이 될 때까지 EB바이러스 감염이 되지 않으니, 전염단핵구증을 더 자주 볼 수 있는 곳은 이들 선진국이다.
젊은 성인에서 전염단핵구증의 잠복기는 약 4~6주다. 피로와 근육통이 1~2주 지속하다 발열, 인후통림프절이 붓는 등의 증상이 나타난다. 주로 목 뒤에 있는 림프절이 붓고 아프며, 이건 우리 몸에서 T세포를 다량으로 만들어내는 것과 관계가 있다. 발진이 생기기도 하며, 간과 비장이 커지기도 한다.
이런 증상들은 2~4주간 지속하며, 권태감과 집중력 저하 등은 수개월까지 가기도 한다. 대부분 자연 치유되나 일부 환자에서는 합병증이 생기기도 하는데, 뇌를 침범한다든지 적혈구가 깨져 빈혈이 생기기도 한다. 합병증으로 간염이 발병하기도 해, 2009년 국내 논문에는 전염단핵구증에 걸린 20대 남자에서 급성 간염이 생긴 사례가 보고된 바 있다.

비정상적으로 림프구가 증가하면 전염단핵구증을 의심해야…

건강한 성인의 혈액에는 1mm3당 4,500-10,000개 정도의 백혈구가 있다. 전염단핵구증에 감염 시 백혈구 수치가 10,000개를 넘어 20,000개에 이른다. 특히 림프구가 증가하는데, 그 중 10% 이상이 비전형 림프구로, 크기도 크고 불규칙한 핵을 가지고 있다. 이 질병의 이름이 전염단핵구증인 건 림프구가 많이 증가하는 데 기인한다. 열이 있고 인두염과 부은 림프절이 있는 성인에서 비정상적으로 생긴 백혈구가 많이 관찰된다면 전염단핵구증을 의심할 수 있다. 거기에 더해 비장까지 커졌다면 진단에 도움이 된다. 과거에는 항체검사도 했지만 위음성, 즉 전염단핵구증에 걸렸는데도 양성으로 나오지 않는 경우가 많아 유용성이 떨어진다. 최근에는 트랜스아미나제(transaminase)라는 간 효소가 80%에서 증가하여 진단에 널리 쓰인다.

전염단핵구증의 치료제의 개발이 필요하다

가장 중요한 치료는 휴식과 진통제다. 잘 쉬면 대부분은 병이 낫는다. 첫 한 달은 비장이 터지는 걸 막기 위해 과도한 활동을 피해야 한다. 염증이 심하면 항염 작용이 있는 스테로이드를 쓰고 싶겠지만, 이 경우 세균 감염의 위험성이 있으므로 피하는 게 좋다. 단 편도선이 너무 커져 기도를 막는다든지, 적혈구가 깨진다든지 할 때는 프레드니졸론(prednisolone)을 쓸 수는 있다. EB바이러스는 헤르페스 바이러스(herpes virus)와 같은 과에 속하지만, 헤르페스에 잘 듣는 아시클로버(acyclovir)는 효과가 없다. 그러니 전염단핵구증의 치료는 그저 면역억제제의 사용을 줄이는 게 고작이다. 키스가 아니면 전염되기 어려우니 격리를 할 필요까진 없지만, 혹시 모르니 음식을 앞에 두고 침을 튀기며 말하는 건 주의를 줄 필요가 있다. 아무튼 EB바이러스의 치료약은 현재로선 없는 상태인데, 이에 대한 설명은 이렇다. EB바이러스는 타액에서 주로 증식하므로 약을 먹어봤자 그 효과가 미치지 않으며, EB바이러스의 증세가 바이러스 탓이라기보다는 우리 몸의 면역반응에서 기인하기 때문이다. EB바이러스가 심각한 증상을 일으키고 심지어 암과도 관계가 있는 만큼 제대로 된 치료약의 개발이 필요하다.

황제 페더러, EB바이러스를 극복하고 성공적으로 복귀하다

EB바이러스를 극복하고, 2010년 호주 오픈 우승을 차지한 로저 페더러
EB바이러스가 드문 질환이 아닌 만큼 우리가 아는 사람 중에서도 환자를 찾을 수 있다. 작년 올림픽에서 박태환과 경쟁을 했던 해켓(Grant Hackett)도 2000년 올림픽 즈음에 EB바이러스에 시달린 바 있는데, 그래서 그다음 올림픽 때는 아내와 키스도 하지 않을 만큼 조심을 했단다.
‘어뢰’라는 별명을 얻었던 수영스타 이안 소프(Ian Thorpe)가 이른 나이에 은퇴한 것도 EB바이러스를 앓았기 때문이라고 한다. 이안 소프와 달리 페더러는 EB바이러스를 극복했고, 2009년 2개의 그랜드슬램 타이틀을 차지하며 다시금 세계랭킹 1위에 복귀했다. 어려운 병을 극복하고 다시금 세계 일인자가 된 그에게 박수를 보내야 하겠다.

Copy of Influence of Greek and Indian Mathematics on Arab Scholars

Copy of Influence of Greek and Indian Mathematics on Muslim Scholars

By Nick Catenacci and Melody TorresInfluence of Greek and Indian Mathematics on Muslim Scholars
Greek and Indian Mathematics
Change Over Time of the Spread of Knowledge
Many books were written by the Greeks and the Indians, laying down basic rules, theorems, and so forth that would prove to be the foundations of Muslim mathematical rules. Among these Greek and Indian mathematical works is the Greek Euclid's "Elements," and--while not a book, it is equally important--is the astrolabe. Originally Greek, it relied on astronomy and mathematics so that a sailor could determine his position while in transit. Muslims scholars adopted this invention, and even made it more mathematically accurate, adding circles indicating azimuths, allowing for more accurate locations to be estimated, and for the Muslims to still be able to pray in the direction of Mecca while in transit.
Islamic scholars, who possessed a passion of gaining knowledge, imported books from Greece and India, whose subjects covered a wide variety of subjects, including astronomy and, especially, mathematics. To house these manuscripts, the Muslims created the House of Wisdom, which housed many Greek and Sanskrit manuscripts, including mathematical books. Here, the works were translated into Arabic, and as Muslims learned more and more from these works, their mathematics took on a very Greek approach, such as Euclid's style of forming and proving. This collection of Greek and Indian mathematical works is a huge source of the influence that Greek and Indian mathematics had on Muslim scholars--especially in the conceptualization of new forms of mathematics.
Collecting the Knowledge
The formation of Arabic mathematics from Greek and Indian mathematical ideas created and led to many fundamental laws of modern-day mathematics. For example:
Abu Ja'far ibn Musa Al-Khwarizmi wrote a book called "Compendious Book on Calculation by Completion and Balancing" on arithmetic. This work used Hindu-Arabic numerals. This book introduced many fundamental mathematical terms, such as algorism--the process of computing with Hindu-Arabic numbers, which led to the modern term "Algorithm"--and probably one of the most essential fields of mathematics: al jabr, translated today as Algebra.
Formation of Knowledge
In his book, "Compendious Book on Calculation by Completion and Balancing" the famed Arabic mathematician Al-Khwarizmi, using an algorithm of Hindu-Arabic numerals, first introduced the concept of "Al Jabr," or as we know it today, Algebra. While it is taken for granted today, this specific field of mathematics led to further advancements in mathematics, such as later developments in Calculus. In Al-Khwarizmi's book, there was introduced a math in which one could mathematically find "variables" in equations--up to five. In modern day schools, this forms the very basis of high school and college mathematics education. So, while as indirect as it is, Greek and Indian mathematics, through its influence on Muslim scholars, caused the development of what is probably the most essential mathematics field known to the modern world
Al Jabr, A.K.A. Algebra
Greek and Indian mathematics affected Muslim scholars all over the Islamic Empire, revolutionizing how scholars then--and now--look at mathematics. This influence was amplified through the use of the trading routes throughout Afro-Eurasia, specifically the Silk Roads. Through this was this new type of mathematics allowed to spread to and from scholars of all nationalities. While originally mostly confined to Greece and India, and later the Islamic Empire, the new type of mathematics later spread all throughout Afro-Eurasia by way of the Silk Roads; since the Silk Roads was mainly composed of indirect trade--meaning that the countries/regions on the far sides of it rarely, if ever, came into direct contact--and that trade between many nations required the goods and ideas to pass through many stations and areas, this new hybrid of mathematics spread quickly to many areas and nationalities of people.
The Influence of Knowledge
As well as influencing the creation of Algebra, Indian mathematics also influenced Arabic numerals, especially the most crucial number in the Arabic--and even the modern--number system: zero. The ancient Greeks, while they excelled in mathematics, did not include the value zero in their number system, while the Indians did, and through Indian influence, so did the Muslims. The value zero, adopted from the Indians, allowed them to make much more precise calculations than the Greeks.

comment to who is ignorant in greek culture and greek history

+xinyiquan666 far more things are created and advanced in greece and influenced back to egypt and middle east and to the world....that's why Greek civillization is considered the greatest civillization in the history Greek gave back egypt and middle east greek art, greek music, greek medicine, greek philosophy, greek law and greek architecture, greek foods etc etc...how do you think today arabs listen to greek music and eat greek foods and study aristotle and say I am the scholar of aristotle.... how about you chinese people?!? why do you study greek science in the school and study greek philosophers, platon and greek math and greek musical theory and draw greek styled art and have greek influenced gandhara art as a antique?!? if chinese civillization is so great?!? Greeks are gave cultures and civillizations to middle east and middle east gave greek cultures and greek civillizations to barbarian germanic european...you learn this at middle school history class and you ignorantly group greeks with other europeans that had nothing to do with greek people....that's like saying you chinese are savage mongolian nomad in living in cold siberia...


watch this how arabs learn greek music..

https://www.youtube.com/watch?v=hKABwoWrMAA
Arabs translated and developed Greek texts and works of music and mastered the musical theory of the music of ancient Greece (i.e. Systema ametabolon, enharmonium, chromatikon, diatonon).[1]
see 4BC-2AD Greek Art and 15AD arab art...arab people still draw far less quality after 1400 later eventhough they were trying to copy greek art in byzantine period...
http://commentsreference.blogspot.com/2015/06/greek-art.html
http://commentsreference.blogspot.com/2015/06/arab-art.html

I am gonna give you and teach you basic and hidden history of greece lesson about the most important and the greatest greek culture and civillization from now on... like to many others who heared weird fabrication and bashing about greek civillization...Is great euclides and herophilos fabrication to you?!?  who fabricated those?!? why do whole world learn about them...it's right that greek history has been fabricated by barbarian germanic scholars....American historians are the cultureless barbarian that you are talking about and actually greek history that you learn in school and group altogether with other barbarian europeans, when greece had nothing to do with them and they were just unknown exotic looking blond barbarians to greeks who had black hair black eyes, is fake fabricated greek history...you also don't learn at school arabs and north africans now listen to greek music and greek foods because of fabrication of germanic scholar like the american scholar you mentioned to make greek civillization sound like one of their kind...
also middle east influence on greece in primitive era is also fabrication...
also phoenicians gave alphabet to greek is also fabrication of germanic european scholar...phoenicians were the descendants of greeks and pelasgoi greeks gave phoenicians their alphabet....watch this video how phoenicians are the descedants of greeks while watching enjoying the soulful greatest greek music that you mongolians lack... https://www.youtube.com/watch?v=u75DPSNUuIc
also the hidden history is that north africans and arabs are the descendants of pelasgoi greeks and ionian greeks...also cananeets are descendants of greeks...jews are descendants of philistines(palestinians), which is one of greek tribe...
also ainu in japan are the descedants of greeksearly egypt was built by greeks also...but fabrication of greek history was hiding some of these facts and some of them are made known to public but not learned in school...
these are the real history of the greatest civillization greece that many people now try to bash and brainwashed with negativity because of fabrication of those barbarian germanic american scholar you talk about...how dare barbarian american scholar try to write greek history when he is barbarian like asian nomad chinese...

vietnamese made khmer rouges

I am not sure if the writer is a Vietnamese or a Khmer with Vietnamese head (kbal yuon, kluon Khmer), but he got history very wrong. He said Khmer Rouge attacked Vietnam unprovoked. The fact of the matter was that Viet soldiers encroached on Khmer border everyday like they are doing now and the KR soldiers tried to stop them, that's why the Viet launched a full scale war and invaded Cambodia.

The writer also said that Vietnam's invasion was "the most profound and true humanitarian act". The writer forgot that Vietnam was the one who created the KR, helped KR came to power in 1975 and then aided and abetted the KR in the killing of millions of Khmer life through Viet tricks. Vietnam did not come to save Khmer life, but invaded to annex more Khmer lands and kill more Khmer life like the K5 Plan. In fact, there are many claims and statistics pointing out that many more Khmers died or were killed after the Viet invasion in 1979.

The writer also accused overseas Khmers for inventing the story of Viet encroachments. No one will believe this claim because people can see with their own eyes that Vietnam are encroaching Khmer territory everyday and that Khmer farmers living along the border are crying everyday because Vietnamese soldiers had encroached on their lands. Does this writer think that these poor and unarmed Khmer farmers are the invaders of Vietnamese territory?

Regarding Champa and Kampuchea Krom, well, it is history but don't claim that they were Viet territory and the Chams and the Khmer Krom were invaders, right?

I believe that Cambodia and Vietnam should be friends, but do you think that friends won't invade or encroach on each other's land, right? I believe that we Khmers can't take back Kampuchea Krom, but we must never allow Vietnam to continue to encroach or chip away our territory on a daily basis. If you think that I have made up the story of Viet encroachments, then you just ask the farmers living along the border and they can tell you that they lost their land everyday.

History should be told the way it had happened, not twisted and turned.

vietnamese send vietnamese people to cambodia to overtake cambodia

The writer forget to mention that everything is Viets plans. In the 1970-75 war they invaded Cambodia using Sihanouk name to cheat Sihanouk and khmer people that they came to help Sihanouk get back as the head of state of Cambodia. At the end of war, they sent their agents to infiltrate in Khmer Rouge administration and tricked Khmer Rouge to kill millions of Khmer people. As the result of the killing, khmers morale were low and Vietnam see it as an opportunity to conquer Cambodia by force. Majority of Khmers at had no choice but to accept Vietnamese out of fear of Khmer Rouge. If they really came to save us they should just leave us alone. Instead in every level Khmer Administration they have Vietnamese advisors everywhere. The keep sending their people illigally to Cambodia every day and the Viets immigrants in Cambodia now stand about 5 millions and among these 200000 to 300000 are viet soldiers hiding in Viet civilians clothes to protect Viet interest. Hun Sen has title as Cambodian PM, but in reality is just slave of the Vietnamese. It's PM who is designed by the Viet to serve viet interest. To Khmer people Hun Sen who had only two years high school education is not smart in leading the country but his master is the one who is smart.

what vietnamese did to cambodian

The Vietnamese are expansionists and colonists. They killed the Khmer people and practice institutional racism and persecutions against the Khmer people’s culture, customs, and celebrations. The Vietnamese relentlessly assault the Khmer langauge  Cambodia has lost a lot to the Vietnamese in terms of natural resources – the entire Mekong Delta region, 22 provinces, islands, sea, historical treasures, and much much more. In fact the Khmer Mekong Delta region has given rise to higher standard of living of millions of Vietnamese. Look up the Vinh Te Canal Project where the Vietnamese supervisors killed the Khmer workers under their charge burried the Khmer people deep in the ground up to their necks and burned them alive. Why don’t you look at the evidence of what the Vietnamese did to the captured American soldiers. Vietnamese are the cruelest people!!   After they invaded Cambodia, the Vietnamese did it again. This time they implemented the Vietnamese K5 genocidal plan that required hundreds of thousands of Cambodians to dig a canal to separate Cambodia from Thailand. Tens of thousands Cambodians were killed. Everything is well documented.Now do you understand why some Cambodians don’t like the Vietnamese because once you know the true nature of the Vietnamese then you clearly see them as little devils going around wreaking havoc the lives of cambodians.You’ve forgot a few important key points: Today’s South Vietnam was a Cambodia territory. Read up on Champa, a kingdom that was completely annihilated by the Vietnamese. During the Vietnam War, Viet Cong was using Cambodia as their santuary (thanks to Sihanouk). The Viet Cong is responsible for the “killing field” in Cambodia.Cambodians by nature and culture are friendly and peaceful people on earth. There are many Cambodians including myself who are trying very hard to make peace with our past and bitter history. However, we have never been left to live as a peaceful nation.  there have been so much loss and suffering inflicted upon Khmer Nation by Vietnam that it is impossible for a Khmer like me to forgive and forget. For other nationalities who know little about the Deep and Dark secret Indochina Policy of Vietnam, they might think that Khmer continued hatred on Vietnam are simply and morally wrong, especially in this 21st Century. For me who have seen many wars directly and secretly involved/created by Vietnam in my beloved Cambodia, there is no way that I have the word “Love” for Vietnam. Many Khmers do not have to look back into the past history to accumulate the Hatred on Vietnamese. We all have seen what has happened to Cambodia and her people since Vietnam invaded our country in 1979. It should not take a Ph.D. or Doctor to understand and know who is running Cambodia behind the science nowadays. Facts are Fact. The facts developing in Cambodia now cannot lie about Vietnam intention on Cambodia. I suggest that you should at least read this attached article to better understand why the Cambodians are afraid, and not hate the Vietnamese. The Cambodians are the victims and not the victimizers. Please, read this article titled “The Costs of Ming Mang’s Assimilation Policy,” on how the Vietnamese; have been eliminating two people of similar civilizations, (Indianized vs. sinic) the Chams and the Cambodians from Kampuchea Krom or Cochinchina, pasted below:Naranhkiri Tith, Ph.D. Professor, International Finance, SAIS, The Johns Hopkins Univeristy Washington DC. May 27, 2013People here don’t seem to realize what is happening because it’s not your home it’s happening to. We as Cambodian despise the Vietnamese “to make a long story short”, after a long fought war, we now have Vietnamese slowly moving in our land trying to conquer what is not theirs. They come and meddle with Cambodian political affairs and are allowed due to a corrupted government. Voting for president with no citizenship there really? C’mon get the heck out of this country.This is the present with other countries trying to invade native land that they have no history or heritage in. We are not dwelling on the past it’s the present. We can play this game as if no one knows why but like I said it’s not your land it’s happening to. The proof is in the pudding, the internet swarms with up to date situations in Cambodia and the Vietnamese are a constant threat to our country. Of course they say they are “Oblivious”. I mean who the heck would say something if they were doing wrong. If you have a fluent Cambodian friend let them be your translator and tell me why Genghis Khan is still alive in Vietnam. I don’t need to say anymore. Read the points and google them up and auctually understand before assuming.

tennis commentators say lies in TV that liar nadal fans created to attack federer's achievement

11/21/2015 | 10:40 PM
oh my goodness the commentator in skysport just said federer is a such a arrogant guy in and off court and that arrogance in court make federer help his longivity...what?!? what is this liar commentators sounds just like nadal fans who make things up?!? and they constantly say federer is playing his best tennis of his life this year?!? what?!? are they kidding?!? seriously at the age of 34 and the decline after monocleusis virus?!? why do they say same nonsensical lies that nadal fans created?!?
 

Federer's serve speed decreased after he got illed from monocleusis virus in 2008

11/21/2015 | 10:11 PM
One of those last aces was 123 mph. Wow. Is Roger getting younger!
 
11/21/2015 | 10:14 PM
125 this ace wow wow
 
11/21/2015 | 10:20 PM
123 mph...He used to serve average 125mph-132mph with occasional 135, 136 mph serve before he got suffered from monocleusis virus in 2008... and after monocleusis virus, his average serve speed descreased to between 122 and 128 mph but at the age of 34 with his illness, he still maintained his body relatively well to produce 123 mph serve...
 

corrupt organization ATP even ban umpire who punish nadal's cheating

+tennis addict It's Nadal officials need to stand up to, not Federer. Nadal insisted that one rare umpire who penalised him for his typical serve time faults be barred from his matches and so that has happened. And Nadal keeps getting away with his gamesmanship/cheating. Shame on the ATP.

Greek keys

Greek keys - origins


Index --- style --- turns --- designs --- compare keys --- corners --- 2 dimensional --- modern --- triangular --- circular --- fractal --- copying --- origins
The Charioteer at Delphi

Who used Greek keys?

The Greek key pattern has been used throughout history and in many places. Since it is a simple geometric pattern, it isn't surprising that so many people have used it. The ancient Greeks certainly used it, as carvings on their temples, and on their pottery. You can see a simple Greek key on the head band of the famous Charioteer statue found at Delphi (see left). The Romans liked the pattern as well, using it in their mosaics. However, it's used elsewhere in the world. The Dongson (or Dong Son) culture, which was centered around the Tonkin gulf in present-day Vietnam used Greek key ornamentation. It has also been used by Hopi people in North America.




An older pattern

This tattoo was found on the hand of a woman, found mummified in the Gobi desert, who lived about 3000 years ago. The spirals going both ways looks like a Greek key. However, a Greek key has a double spiral, which not only winds to the centre, but also winds out again as well. These are simple spirals. Also Greek keys tend to connect from one pattern to the next, and these are just simple repetitions. However, the flow of the patterns feels like a Greek key, and I wonder if this is a forerunner of the real Greek key pattern.
This pattern is on Flikr here and there are photos of the original mummy here. Thanks to Tim for bringing it to my notice!

What do Greek keys mean?

Various claims have been made for what a Greek key means. There may be a connection with the labyrinth where Theseus fought the Minotaur. A Greek bowl in the British museum shows Theseus dragging the Minotaur from the labyrinth, which is indicated by a Greek key frieze. You can make a Cretan or classical maze using a Greek key (see right), and many mazes have Greek keys embedded in a design, especially Roman mazes.
Other suggested meanings are stylised waves, snakes, symbolizing the bonds of love, friendship and devotion, eternal life, the four cardinal points, the meander of life, creative energy, the four seasons, etc. Take your pick! I prefer the waves. There are curved forms of Greek keys which look very like seawaves. This pattern Curved Greek key is on the shield of Philip, father of Alexander the Great. The shield also has a more conventional Greek key pattern. This website only describes the square forms.

L-카르니틴은 지방을 태워준다

지방산의 물질 대사[편집]

카르니틴은 세포에 작용하여 지방산을 미토콘드리아로 옮긴 뒤, 지방산을 아세트산 이온(CH3COO-)과 함께 반응시켜 물과 이산화탄소로 분해하여 에너지로 바꾼다. 이 물질 대사는 탄수화물도 마찬가지로 작용된다. 이리하여 만들어지는 카르니틴이 아세틸-L-카르니틴이다.[6]

There are many claims that Greek has millions of words -- 70 million is the biggest number I have seen so far.

In truth, it's not possible to count exactly how many words there are in any language because (this seems crazy, but it's true) there's no universal definition of "word". But no language has more than about 400,000 words, and the Greek language, sorry to say, has somewhere in the region of 100,000 to 200,000. English probably has slightly more, about 250,000.

A typical English dictionary lists about 80,000 words, and about 5% of those -- 4,000 -- are borrowed from Greek. If we extrapolate from that, we can say that English has 250,000 words, of which about 12,500 come from Greek.

But it doesn't really matter very much. Most people only know about 20,000 to 50,000 words, and for most everyday conversations only use a few thousand. The number of words in a language doesn't tell you anything about how good the language is: what counts is how easy it is to use those words to express what you want to say.

classical music is much more complex in terms of the music itself

I find that they are both complicated in different ways. Classical is more complex in terms of the composition aspect, while jazz is more complicated with the performing.

+omnipotentum  He should also be penalised for so often exceeding the serve time limits in matches, but the umpires do nothing- Nadal insisted that one umpire who acted be barred from his matches. Shameful! And yes, he's been a  cheat for most of his career.
