Canal Rays
An anode ray (also positive ray or canal ray) is a beam of positive ions that is created by certain types of gas-discharge tubes. They were first observed in Crookes tubes during experiments by the German scientist Eugen Goldstein, in 1886. Later work on anode rays by Wilhelm Wien and J. J. Thomson led to the development of mass spectrometry. Anode ray tube Goldstein used a gas-discharge tube which had a perforated cathode. When an electrical potential of several thousand volts is applied between the cathode and anode, faint luminous "rays" are seen extending from the holes in the back of the cathode. These rays are beams of particles moving in a direction opposite to the "cathode rays", which are streams of electrons which move toward the anode. Goldstein called these positive rays ''Kanalstrahlen'', "channel rays", or "canal rays", because these rays passed through the holes or ''channels'' in the cathode. The process by which anode rays are formed in a gas-discharge anode r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ha-Yishuv
Yishuv ( he, ישוב, literally "settlement"), Ha-Yishuv ( he, הישוב, ''the Yishuv''), or Ha-Yishuv Ha-Ivri ( he, הישוב העברי, ''the Hebrew Yishuv''), is the body of Jewish residents in the Land of Israel (corresponding to the southern part of Ottoman Syria until 1918, OETA South 1917–1920, and Mandatory Palestine 1920–1948) prior to the establishment of the State of Israel in 1948. The term came into use in the 1880s, when there were about 25,000 Jews living across the Land of Israel and continued to be used until 1948, by which time there were some 630,000 Jews there. The term is still in use to denote the pre-1948 Jewish residents in the Land of Israel. A distinction is sometimes drawn between the Old Yishuv and the New Yishuv. The Old Yishuv refers to all the Jews living in the Land of Israel before the first Zionist immigration wave (''aliyah'') of 1882, and to their descendants who kept the old, non-Zionist way of life until 1948. The Old Yishuv resid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russian Academy Of Sciences
The Russian Academy of Sciences (RAS; russian: Росси́йская акаде́мия нау́к (РАН) ''Rossíyskaya akadémiya naúk'') consists of the national academy of Russia; a network of scientific research institutes from across the Russian Federation; and additional scientific and social units such as libraries, publishing units, and hospitals. Peter the Great established the Academy (then the St. Petersburg Academy of Sciences) in 1724 with guidance from Gottfried Leibniz. From its establishment, the Academy benefitted from a slate of foreign scholars as professors; the Academy then gained its first clear set of goals from the 1747 Charter. The Academy functioned as a university and research center throughout the mid-18th century until the university was dissolved, leaving research as the main pillar of the institution. The rest of the 18th century continuing on through the 19th century consisted of many published academic works from Academy scholars and a few Ac ...

Iron Curtain
The Iron Curtain was the political boundary dividing Europe into two separate areas from the end of World War II in 1945 until the end of the Cold War in 1991. The term symbolizes the efforts by the Soviet Union (USSR) to block itself and its satellite states from open contact with the West, its allies and neutral states. On the east side of the Iron Curtain were the countries that were connected to or influenced by the Soviet Union, while on the west side were the countries that were NATO members, or connected to or influenced by the United States; or nominally neutral. Separate international economic and military alliances were developed on each side of the Iron Curtain. It later became a term for the physical barrier of fences, walls, minefields, and watchtowers that divided the "east" and "west". The Berlin Wall was also part of this physical barrier. The nations to the east of the Iron Curtain were Poland, East Germany, Czechoslovakia, Hungary, Romania, Bulgaria, Albania, ...

Chaim Weizmann
Chaim Azriel Weizmann ( he, חיים עזריאל ויצמן ', russian: Хаим Евзорович Вейцман, ''Khaim Evzorovich Veytsman''; 27 November 1874 – 9 November 1952) was a Russian-born biochemist, Zionist leader and Israeli statesman who served as president of the Zionist Organization and later as the first president of Israel. He was elected on 16 February 1949, and served until his death in 1952. Weizmann was fundamental in obtaining the Balfour Declaration and later convincing the United States government to recognize the newly formed State of Israel. As a biochemist, Weizmann is considered to be the 'father' of industrial fermentation. He developed the acetone–butanol–ethanol fermentation process, which produces acetone, n-butanol and ethanol through bacterial fermentation. His acetone production method was of great importance in the manufacture of cordite explosive propellants for the British war industry during World War I. He founded the Sieff ...

Mandatory Palestine
Mandatory Palestine ( ar, فلسطين الانتدابية '; he, פָּלֶשְׂתִּינָה (א״י) ', where "E.Y." indicates ''’Eretz Yiśrā’ēl'', the Land of Israel) was a geopolitical entity established between 1920 and 1948 in the region of Palestine under the terms of the League of Nations Mandate for Palestine. During the First World War (1914–1918), an Arab uprising against Ottoman rule and the British Empire's Egyptian Expeditionary Force under General Edmund Allenby drove the Ottoman Turks out of the Levant during the Sinai and Palestine Campaign. The United Kingdom had agreed in the McMahon–Hussein Correspondence that it would honour Arab independence if the Arabs revolted against the Ottoman Turks, but the two sides had different interpretations of this agreement, and in the end, the United Kingdom and France divided the area under the Sykes–Picot Agreementan act of betrayal in the eyes of the Arabs. Further complicating the issue was t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rehovot
Rehovot ( he, רְחוֹבוֹת ''Rəḥōvōt'', ar, رحوڤوت ''Reḥūfūt'') is a city in the Central District of Israel, about south of Tel Aviv. In it had a population of . Etymology Israel Belkind, founder of the Bilu movement, proposed the name "Rehovot" (lit. 'wide expanses') based on Genesis 26:22: "And he called the name of it ''Rehoboth''; and he said: 'For now the Lord hath made room for us, and we shall be fruitful in the land'." This Bible verse is also inscribed in the city's logo. The biblical town of '' Rehoboth'' was located in the Negev Desert. History Ottoman era Rehovot was established in 1890 by pioneers of the First Aliyah on the coastal plain near a site called ''Khirbat Deiran'', an "abandoned or sparsely populated" estate, which now lies in the center of the built-up area of the city. According to Marom, Deiran offered "a convenient launching pad for early land purchase initiatives which shaped the pattern of Jewish settlement until the b ...

Daniel Sieff Research Institute
Daniel is a masculine given name and a surname of Hebrew origin. It means "God is my judge"Hanks, Hardcastle and Hodges, ''Oxford Dictionary of First Names'', Oxford University Press, 2nd edition, , p. 68. (cf. Gabriel—"God is my strength"), and derives from two early biblical figures, primary among them Daniel from the Book of Daniel. It is a common given name for males, and is also used as a surname. It is also the basis for various derived given names and surnames. Background The name evolved into over 100 different spellings in countries around the world.

Infra-red Spectroscopy
Infrared spectroscopy (IR spectroscopy or vibrational spectroscopy) is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms. It can be used to characterize new materials or identify and verify known and unknown samples. The method or technique of infrared spectroscopy is conducted with an instrument called an infrared spectrometer (or spectrophotometer) which produces an infrared spectrum. An IR spectrum can be visualized in a graph of infrared light absorbance (or transmittance) on the vertical axis vs. frequency, wavenumber or wavelength on the horizontal axis. Typical units of wavenumber used in IR spectra are reciprocal centimeters, with the symbol cm−1. Units of IR wavelength are commonly given in micrometers (formerly called "microns"), symbol μm, which are related to the wavenumber in a reciprocal way. A co ...
