Tērvete
Tērvete (liv. ''Terwenden'', german: Hofzumberge) is a village in Tērvete Parish, Dobele Municipality in the Semigallia region of Latvia. It is famous for the historic hillfort built for the kings of Western Semigallia (Zemgale) in the Middle Ages. History According to popular legend the Semigallians, Semigallian king Nameisis made a ring called the "namejs" so he could be identified by his family. But his enemies got hold of this information and sought the ring to kill the king (during a war) to have victories. The villagers also created these rings in order to protect the King. And for this reason Namejs is a popular ring for Latvians. In 1287, the Semigallian castle was destroyed by the Livonian Order. In 1335, the wooden castle ''Hof zum Berg'' Kalnamuiža was built by the Order of Livonia near to the site of the former Semigallian fortifications, destroyed by the Grand Duchy of Lithuania, Lithuanian forces in 1345.

Great Soviet Encyclopedia
The ''Great Soviet Encyclopedia'' (GSE; ) is one of the largest Russian-language encyclopedias, published in the Soviet Union from 1926 to 1990. After 2002, the encyclopedia's data was partially included into the later ''Bolshaya rossiyskaya entsiklopediya'' (or '' Great Russian Encyclopedia'') in an updated and revised form. The GSE claimed to be "the first Marxist–Leninist general-purpose encyclopedia". Origins The idea of the ''Great Soviet Encyclopedia'' emerged in 1923 on the initiative of Otto Schmidt, a member of the Russian Academy of Sciences. In early 1924 Schmidt worked with a group which included Mikhail Pokrovsky, (rector of the Institute of Red Professors), Nikolai Meshcheryakov (Former head of the Glavit, the State Administration of Publishing Affairs), Valery Bryusov (poet), Veniamin Kagan (mathematician) and Konstantin Kuzminsky to draw up a proposal which was agreed to in April 1924. Also involved was Anatoly Lunacharsky, People's Commissar of Education ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Medical Congress
The International Medical Congress (french: Congrès International de Médecine) was a series of international scientific conferences on medicine that took place, periodically, from 1867 until 1913. The idea of such a congress came in 1865, during the third annual Medical Congress of France; Professor Henri Giutrac proposed holding an international medical conference in 1867, taking advantage of the fact that physicians and surgeons from all over the world would surely be in Paris to attend that year's International Exhibition. The first congress was a great success; it enjoyed the patronage of the French Government, having been officially attended by Victor Duruy, Minister of Public Instruction, and had several honorary members selected from foreign diplomatic bodies and learned societies. Congresses Proposed Congress The 18th Congress was due to be held in Munich in 1917, as unanimously agreed by the permanent commission of the International Congress at the 17th Congre ...

Anthrax
Anthrax is an infection caused by the bacterium ''Bacillus anthracis''. It can occur in four forms: skin, lungs, intestinal, and injection. Symptom onset occurs between one day and more than two months after the infection is contracted. The skin form presents with a small blister with surrounding swelling that often turns into a painless ulcer with a black center. The inhalation form presents with fever, chest pain and shortness of breath. The intestinal form presents with diarrhea (which may contain blood), abdominal pains, nausea and vomiting. The injection form presents with fever and an abscess at the site of drug injection. According to the USA's Centers for Disease Control and Prevention, the first clinical descriptions of cutaneous anthrax were given by Maret in 1752 and Fournier in 1769. Before that anthrax had been described only through historical accounts. The Prussian scientist Robert Koch (1843–1910) was the first to identify ''Bacillus anthracis'' as the bacteri ...

Smallpox
Smallpox was an infectious disease caused by variola virus (often called smallpox virus) which belongs to the genus Orthopoxvirus. The last naturally occurring case was diagnosed in October 1977, and the World Health Organization (WHO) certified the global eradication of the disease in 1980, making it the only human disease to be eradicated. The initial symptoms of the disease included fever and vomiting. This was followed by formation of ulcers in the mouth and a skin rash. Over a number of days, the skin rash turned into the characteristic fluid-filled blisters with a dent in the center. The bumps then scabbed over and fell off, leaving scars. The disease was spread between people or via contaminated objects. Prevention was achieved mainly through the smallpox vaccine. Once the disease had developed, certain antiviral medication may have helped. The risk of death was about 30%, with higher rates among babies. Often, those who survived had extensive scarring of their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syphilis
Syphilis () is a sexually transmitted infection caused by the bacterium ''Treponema pallidum'' subspecies ''pallidum''. The signs and symptoms of syphilis vary depending in which of the four stages it presents (primary, secondary, latent, and tertiary). The primary stage classically presents with a single chancre (a firm, painless, non-itchy skin ulceration usually between 1 cm and 2 cm in diameter) though there may be multiple sores. In secondary syphilis, a diffuse rash occurs, which frequently involves the palms of the hands and soles of the feet. There may also be sores in the mouth or vagina. In latent syphilis, which can last for years, there are few or no symptoms. In tertiary syphilis, there are gummas (soft, non-cancerous growths), neurological problems, or heart symptoms. Syphilis has been known as "the great imitator" as it may cause symptoms similar to many other diseases. Syphilis is most commonly spread through sexual activity. It may also be transmi ...

Tuberculosis
Tuberculosis (TB) is an infectious disease usually caused by '' Mycobacterium tuberculosis'' (MTB) bacteria. Tuberculosis generally affects the lungs, but it can also affect other parts of the body. Most infections show no symptoms, in which case it is known as latent tuberculosis. Around 10% of latent infections progress to active disease which, if left untreated, kill about half of those affected. Typical symptoms of active TB are chronic cough with blood-containing mucus, fever, night sweats, and weight loss. It was historically referred to as consumption due to the weight loss associated with the disease. Infection of other organs can cause a wide range of symptoms. Tuberculosis is spread from one person to the next through the air when people who have active TB in their lungs cough, spit, speak, or sneeze. People with Latent TB do not spread the disease. Active infection occurs more often in people with HIV/AIDS and in those who smoke. Diagnosis of active TB is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
