North Korea
North Korea, officially the Democratic People's Republic of Korea (DPRK), is a country in East Asia. It constitutes the northern half of the Korea, Korean Peninsula and shares borders with China and Russia to the north, at the Yalu River, Yalu (Amnok) and Tumen River, Tumen rivers, and South Korea to the south at the Korean Demilitarized Zone. North Korea's border with South Korea is a disputed border as both countries claim the entirety of the Korean Peninsula. The country's western border is formed by the Yellow Sea, while its eastern border is defined by the Sea of Japan. North Korea, like South Korea, its southern counterpart, claims to be the legitimate government of the entire peninsula and List of islands of North Korea, adjacent islands. Pyongyang is the capital and largest city. In 1910, Korean Empire, Korea was Korea under Japanese rule, annexed by the Empire of Japan. In 1945, after the Surrender of Japan, Japanese surrender at the End of World War II in Asia, end ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photorefractive Keratectomy
Photorefractive keratectomy (PRK) and laser-assisted sub-epithelial keratectomy (or laser epithelial keratomileusis) (LASEK) are laser eye surgery procedures intended to correct a person's vision, reducing dependency on glasses or contact lenses. LASEK and PRK permanently change the shape of the anterior central cornea using an excimer laser to ablate (remove by vaporization) a small amount of tissue from the corneal stroma at the front of the eye, just under the corneal epithelium. The outer layer of the cornea is removed prior to the ablation. A computer system tracks the patient's eye position 60 to 4,000 times per second, depending on the specifications of the laser that is used. The computer system redirects laser pulses for precise laser placement. Most modern lasers will automatically center on the patient's visual axis and will pause if the eye moves out of range and then resume ablating at that point after the patient's eye is re-centered. The outer layer of the cornea, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phase-shift Keying
Phase-shift keying (PSK) is a digital modulation process which conveys data by changing (modulating) the phase of a constant frequency reference signal (the carrier wave). The modulation is accomplished by varying the sine and cosine inputs at a precise time. It is widely used for wireless LANs, RFID and Bluetooth communication. Any digital modulation scheme uses a finite number of distinct signals to represent digital data. PSK uses a finite number of phases, each assigned a unique pattern of binary digits. Usually, each phase encodes an equal number of bits. Each pattern of bits forms the symbol that is represented by the particular phase. The demodulator, which is designed specifically for the symbol-set used by the modulator, determines the phase of the received signal and maps it back to the symbol it represents, thus recovering the original data. This requires the receiver to be able to compare the phase of the received signal to a reference signal such a system is termed c ...

People's Republic Of Korea
The People's Republic of Korea (PRK) was a short-lived provisional government that was organized at the time of the surrender of the Empire of Japan at the end of World War II. It was proclaimed on 6 September 1945, as Korea was being divided into two occupation zones, with the Soviet Union occupying the north and the United States occupying the south. Based on a network of people's committees, it presented a program of radical social change. In the south, the US military government outlawed the PRK on 12 December 1945. In the north, the Soviet authorities co-opted the committees and merged them into the political structure of the emerging Democratic People's Republic of Korea (North Korea). History Establishment On 15 August 1945, the Japanese Empire surrendered to the Allies. The Imperial Japanese authorities requested that a government be established to ensure the safety of their persons and property after the occupation ended. Whilst the Soviet Union continued to fight ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People's Republic Of Kampuchea
The People's Republic of Kampuchea (PRK), UNGEGN: , ALA-LC: ; vi, Cộng hòa Nhân dân Campuchia was a partially recognised state in Southeast Asia supported by Vietnam which existed from 1979 to 1989. It was founded in Cambodia by the Kampuchean United Front for National Salvation, a group of Cambodian communists who were dissatisfied with the Khmer Rouge due to its oppressive rule of Cambodia and defected from it after the overthrow of Democratic Kampuchea, Pol Pot's government. Brought about by an invasion from Vietnam, which routed the Khmer Rouge armies, it had Vietnam and the Soviet Union as its main allies. The PRK failed to secure United Nations endorsement due to the diplomatic intervention of China, the United Kingdom, the United States and the ASEAN countries. The Cambodian seat at the United Nations was held by the Coalition Government of Democratic Kampuchea, which was the Khmer Rouge in coalition with two non-communist guerrilla factions. However, the PRK w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Kent (Amtrak Station)
Port Kent station is an Amtrak intercity train station in Port Kent, Essex County, New York. The station is an open platformed shelter. The train only stops at this station when the Lake Champlain Transportation Company Port Kent– Burlington Ferry is in operation from May to October (typically Columbus Day). The Delaware and Hudson Railroad built a freight station on the shores of Port Kent sometime between 1875 and 1876, and an open shelter in 1911, similar to the existing one. Amtrak has stopped at the site since April 24, 1977, but the existing shelter was only established in 1989. The station has one low-level side platform A side platform (also known as a marginal platform or a single-face platform) is a platform positioned to the side of one or more railway tracks or guideways at a railway station, tram stop, or transitway. A station having dual side platform ... on the west side of the single track. References External links Port Kent Amtrak Station (USA Rail ...

Phosphoribulokinase
Phosphoribulokinase (PRK) () is an essential photosynthetic enzyme that catalyzes the ATP-dependent phosphorylation of ribulose 5-phosphate (RuP) into ribulose 1,5-bisphosphate (RuBP), both intermediates in the Calvin Cycle. Its main function is to regenerate RuBP, which is the initial substrate and CO2-acceptor molecule of the Calvin Cycle. PRK belongs to the family of transferase enzymes, specifically those transferring phosphorus-containing groups (phosphotransferases) to an alcohol group acceptor. Along with ribulose 1,5-bisphosphate carboxylase/oxygenase (RuBisCo), phosphoribulokinase is unique to the Calvin Cycle. Therefore, PRK activity often determines the metabolic rate in organisms for which carbon fixation is key to survival. Much initial work on PRK was done with spinach leaf extracts in the 1950s; subsequent studies of PRK in other photosynthetic prokaryotic and eukaryotic organisms have followed. The possibility that PRK might exist was first recognized by Weissbach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
