President Of Germany (1919–1945)
The president of the Reich (german: Reichspräsident) was the German head of state under the Weimar constitution, which was officially in force from 1919 to 1945. In English he was usually simply referred to as the president of Germany. The Weimar constitution created a semi-presidential system in which power was divided between president, cabinet and parliament. The ''Reichspräsident'' was directly elected under universal adult suffrage for a seven-year term. It was intended that the president would rule in conjunction with the Reichstag (legislature) and that his emergency powers would be exercised only in extraordinary circumstances, but the political instability of the Weimar period, and a paralysing factionalism in the legislature, meant that the president came to occupy a position of considerable power, capable of legislating by decree and appointing and dismissing governments at will. In 1934, after the death of President Hindenburg, Adolf Hitler, already chancellor, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I Reparations
Following the ratification of article 231 of the Treaty of Versailles at the conclusion of World War I, the Central Powers were made to give war reparations to the Allied Powers. Each of the defeated powers was required to make payments in either cash or kind. Because of the financial situation in Austria, Hungary, and Turkey after the war, few to no reparations were paid and the requirements for reparations were cancelled. Bulgaria, having paid only a fraction of what was required, saw its reparation figure reduced and then cancelled. Historians have recognized the German requirement to pay reparations as the "chief battleground of the post-war era" and "the focus of the power struggle between France and Germany over whether the Versailles Treaty was to be enforced or revised." The Treaty of Versailles (signed in 1919) and the 1921 London Schedule of Payments required Germany to pay 132 billion gold marks ll values are contemporary, unless otherwise stated in reparations ...

Estrogen
Estrogen or oestrogen is a category of sex hormone responsible for the development and regulation of the female reproductive system and secondary sex characteristics. There are three major endogenous estrogens that have estrogenic hormonal activity: estrone (E1), estradiol (E2), and estriol (E3). Estradiol, an estrane, is the most potent and prevalent. Another estrogen called estetrol (E4) is produced only during pregnancy. Estrogens are synthesized in all vertebrates and some insects. Their presence in both vertebrates and insects suggests that estrogenic sex hormones have an ancient evolutionary history. Quantitatively, estrogens circulate at lower levels than androgens in both men and women. While estrogen levels are significantly lower in males than in females, estrogens nevertheless have important physiological roles in males. Like all steroid hormones, estrogens readily diffuse across the cell membrane. Once inside the cell, they bind to and activate estrogen receptors (E ...

Walter Bock
Walter Bock (20 January 1895 – 25 October 1948)Death record Nr. 3271/Köln I for Ludwig Walter Robert Bock of Oct. 26, 1948, Landesarchiv NRW, Duisburg was a German chemist who developed styrene-butadiene copolymer by emulsion polymerization as a synthetic rubber (SBR). Early life Walter Bock was born on January 10, 1895 in the small village of Wenzen (now part of Einbeck) in the Duchy of Brunswick. He was the fourth of nine children. His father, Wilhelm Bock, was the sole teacher in Wenzen. From 1905 to 1914 Bock attended high school in Brunswick. Immediately after graduation he joined the army and served as an officer in World War I. He commanded an infantry company until he was wounded in July 1918. In October 1918 he began studying chemistry. After receiving his Ph.D. from the University of Göttingen in October 1921, Bock found employment as chemist at the Köln Rottweil AG in Premnitz. In the fall of 1924 Bock joined the Dr. Zellner laboratories in Berlin, where he to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Styrene-butadiene
Styrene-butadiene or styrene-butadiene rubber (SBR) describe families of synthetic rubbers derived from styrene and butadiene (the version developed by Goodyear is called Neolite). These materials have good abrasion resistance and good aging stability when protected by additives. In 2012, more than 5.4 million tonnes of SBR were processed worldwide. About 50% of car tires are made from various types of SBR. The styrene/butadiene ratio influences the properties of the polymer: with high styrene content, the rubbers are harder and less rubbery. SBR is not to be confused with the thermoplastic elastomer, styrene-butadiene block copolymer, although being derived from the same monomers. Types of SBR SBR is derived from two monomers, styrene and butadiene. The mixture of these two monomers is polymerized by two processes: from solution (S-SBR) or as an emulsion (E-SBR). E-SBR is more widely used. Emulsion polymerization E-SBR produced by emulsion polymerization is initiated by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Werner Forssmann
Werner Theodor Otto Forßmann (Forssmann in English; ; 29 August 1904 – 1 June 1979) was a German researcher and physician from Germany who shared the 1956 Nobel Prize in Medicine (with Andre Frederic Cournand and Dickinson W. Richards) for developing a procedure that allowed cardiac catheterization. In 1929, he put himself under local anesthesia and inserted a catheter into a vein of his arm. Not knowing if the catheter might pierce a vein, he put his life at risk. Forssmann was nevertheless successful; he safely passed the catheter into his heart. Early life Forssmann was born in Berlin on 29 August 1904. Upon graduating from , he entered the University of Berlin to study medicine, passing the State Examination in 1929. Career He hypothesized that a catheter could be inserted directly into the heart, for such applications as directly delivering drugs, injecting radiopaque dyes, or measuring blood pressure. The fear at the time was that such an intrusion into the heart w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardiac Catheterization
Cardiac catheterization (heart cath) is the insertion of a catheter into a chamber or vessel of the heart. This is done both for diagnostic and interventional purposes. A common example of cardiac catheterization is coronary catheterization that involves catheterization of the coronary arteries for coronary artery disease and myocardial infarctions ("heart attacks"). Catheterization is most often performed in special laboratories with fluoroscopy and highly maneuverable tables. These "cath labs" are often equipped with cabinets of catheters, stents, balloons, etc. of various sizes to increase efficiency. Monitors show the fluoroscopy imaging, electrocardiogram (ECG), pressure waves, and more. Uses Coronary angiography is a diagnostic procedure that allows visualization of the coronary vessels. Fluoroscopy is used to visualize the lumens of the arteries as a 2-D projection. Should these arteries show narrowing or blockage, then techniques exist to open these arteries. Percutane ...

His landmark novel '' All Quiet on the Western Front'' (1928), based on his experience in the Imperial German Army during World War I, was an international bestseller which created a new literary genre, and was adapted into multiple films. Remarque's anti-war themes led to his condemnation by Nazi propaganda minister Joseph Goebbels as "unpatriotic". He was able to use his literary success to relocate to Switzerland and the United States, where he became a naturalized citizen. Early life Remarque was born on 22 June 1898, as Erich Paul Remark, to Peter Franz Remark and Anna Maria (), a working-class Roman Catholic family in Osnabrück. He was never close with his father, a bookbinder, but he was close with his mother and he began using the middle name Maria after World War I in her honor. Remarque was the third of four children of Peter and Anna. His siblin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
