Pope Vitalian Illustration
The pope ( la, papa, from el, πάππας, translit=pappas, 'father'), also known as supreme pontiff ( or ), Roman pontiff () or sovereign pontiff, is the bishop of Rome (or historically the patriarch of Rome), head of the worldwide Catholic Church, and has also served as the head of state or sovereign of the Papal States and later the Vatican City State since the eighth century. From a Catholic viewpoint, the primacy of the bishop of Rome is largely derived from his role as the apostolic successor to Saint Peter, to whom primacy was conferred by Jesus, who gave Peter the Keys of Heaven and the powers of "binding and loosing", naming him as the "rock" upon which the Church would be built. The current pope is Francis, who was elected on 13 March 2013. While his office is called the papacy, the jurisdiction of the episcopal see is called the Holy See. It is the Holy See that is the sovereign entity by international law headquartered in the distinctively independent Vatican Ci ...

Euphrates
The Euphrates () is the longest and one of the most historically important rivers of Western Asia. Tigris–Euphrates river system, Together with the Tigris, it is one of the two defining rivers of Mesopotamia ( ''the land between the rivers''). Originating in Turkey, the Euphrates flows through Syria and Iraq to join the Tigris in the Shatt al-Arab, which empties into the Persian Gulf. Etymology The Ancient Greek form ''Euphrátēs'' ( grc, Εὐφράτης, as if from Greek εὖ "good" and φράζω "I announce or declare") was adapted from Old Persian 𐎢𐎳𐎼𐎠𐎬𐎢 ''Ufrātu'', itself from Elamite language, Elamite 𒌑𒅁𒊏𒌅𒅖 ''ú-ip-ra-tu-iš''. The Elamite name is ultimately derived from a name spelt in cuneiform as 𒌓𒄒𒉣 , which read as Sumerian language, Sumerian is "Buranuna" and read as Akkadian language, Akkadian is "Purattu"; many cuneiform signs have a Sumerian pronunciation and an Akkadian pronunciation, taken from a Sumerian word a ...

Tikal
Tikal () (''Tik’al'' in modern Mayan orthography) is the ruin of an ancient city, which was likely to have been called Yax Mutal, found in a rainforest in Guatemala. It is one of the largest archeological sites and urban centers of the pre-Columbian Maya civilization. It is located in the archeological region of the Petén Basin in what is now northern Guatemala. Situated in the department of El Petén, the site is part of Guatemala's Tikal National Park and in 1979 it was declared a UNESCO World Heritage Site. Tikal was the capital of a conquest state that became one of the most powerful kingdoms of the ancient Maya. Though monumental architecture at the site dates back as far as the 4th century BC, Tikal reached its apogee during the Classic Period, c. 200 to 900. During this time, the city dominated much of the Maya region politically, economically, and militarily, while interacting with areas throughout Mesoamerica such as the great metropolis of Teotihuacan in the dista ...

Snake Lord
Snakes are elongated, limbless, carnivorous reptiles of the suborder Serpentes . Like all other squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads ( cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, although this rule is not universal (see Amphisbaenia, Di ...

Second Tikal-Calakmul War
The second (symbol: s) is the unit of time in the International System of Units (SI), historically defined as of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each (24 × 60 × 60 = 86400). The current and formal definition in the International System of Units ( SI) is more precise:The second ..is defined by taking the fixed numerical value of the caesium frequency, Δ''ν''Cs, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be when expressed in the unit Hz, which is equal to s−1. This current definition was adopted in 1967 when it became feasible to define the second based on fundamental properties of nature with caesium clocks. Because the speed of Earth's rotation varies and is slowing ever so slightly, a leap second is added at irregular intervals to civil time to keep clocks in sync with Earth's rotation. Uses Analog clocks and watches often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medicine
Medicine is the science and practice of caring for a patient, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others. Medicine has been practiced since prehistoric times, and for most of this time it was an art (an area of skill and knowledge), frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for healing, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pharmacology
Pharmacology is a branch of medicine, biology and pharmaceutical sciences concerned with drug or medication action, where a drug may be defined as any artificial, natural, or endogenous (from within the body) molecule which exerts a biochemical or physiological effect on the cell, tissue, organ, or organism (sometimes the word ''pharmacon'' is used as a term to encompass these endogenous and exogenous bioactive species). More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals. The field encompasses drug composition and properties,functions,sources,synthesis and drug design, molecular and cellular mechanisms, organ/systems mechanisms, signal transduction/cellular communication, molecular diagnostics, interactions, chemical biology, therapy, and medical applications and antipathogenic capabilities. ...

Western Turkic Khaganate
The Western Turkic Khaganate () or Onoq Khaganate ( otk, 𐰆𐰣:𐰸:𐰉𐰆𐰑𐰣, On oq budun, Ten arrow people) was a Turkic khaganate in Eurasia, formed as a result of the wars in the beginning of the 7th century (593–603 CE) after the split of the Turkic Khaganate (founded in the 6th century on the Mongolian Plateau by the Ashina clan) into a western and an eastern Khaganate. The whole confederation was called ''Onoq'', meaning "ten arrows". According to a Chinese source, the Western Turks were organized into ten divisions. The khaganate's capitals were Navekat (summer capital) and Suyab (principal capital), both situated in the Chui River valley of Kyrgyzstan, to the east of Bishkek. Tong Yabgu's summer capital was near Tashkent and his winter capital Suyab. The Western Turkic Khaganate was subjugated by the Tang dynasty in 657 and continued as its vassal until their collapse.

Conquest Of The Western Turks
The conquest of the Western Turks, known as the Western Tujue in Chinese sources, was a military campaign in 655–657 led by the Tang dynasty generals Su Dingfang and Cheng Zhijie against the Western Turkic Khaganate ruled by Ashina Helu. The Tang campaigns against the Western Turks began in 640 with the annexation of the Tarim Basin oasis state Gaochang, an ally of the Western Turks. Several of the oasis states had once been vassals of the Tang dynasty, but switched their allegiance to the Western Turks when they grew suspicious of the military ambitions of the Tang. Tang expansion into Central Asia continued with the conquest of Karasahr in 644 and Kucha in 648. Cheng Zhijie commanded the first foray against the West Tujue, and in 657 Su Dingfang commanded the main army dispatched against the Western Turks, while the Turkic generals Ashina Mishe and Ashina Buzhen led the side divisions. The Tang troops were reinforced by cavalry supplied by the Uyghurs, a tribe that had been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
