Humanae Vitae
(Latin, meaning 'Of Human Life') is an encyclical written by Pope Paul VI and dated 25 July 1968. The text was issued at a Vatican press conference on 29 July. Subtitled ''On the Regulation of Birth'', it re-affirmed the teaching of the Catholic Church regarding married love, responsible parenthood, and the rejection of artificial contraception. In formulating his teaching he explained why he did not accept the conclusions of the Pontifical Commission on Birth Control established by his predecessor, Pope John XXIII, a commission he himself had expanded. Mainly because of its restatement of the Church's opposition to artificial contraception, the encyclical was politically controversial. It dogmaticized a conservative interpretation of traditional Church moral teaching on the sanctity of life in the context of human intervention in fertility and the procreative and unitive nature of Catholic conjugal relations. It was the last of Paul's seven encyclicals. Summary Affirm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burkina Faso
Burkina Faso is a landlocked country in West Africa, bordered by Mali to the northwest, Niger to the northeast, Benin to the southeast, Togo and Ghana to the south, and Ivory Coast to the southwest. It covers an area of 274,223 km2 (105,878 sq mi). In 2024, the country had an estimated population of approximately 23,286,000. Previously called the Republic of Upper Volta (1958–1984), it was Geographical renaming, renamed Burkina Faso by then-List of heads of state of Burkina Faso, president Thomas Sankara. Its citizens are known as Burkinabes, and its Capital city, capital and largest city is Ouagadougou. The largest ethnic group in Burkina Faso is the Mossi people, who settled the area in the 11th and 13th centuries. They established powerful Mossi Kingdoms, kingdoms such as Ouagadougou, Tenkodogo, and Yatenga. In 1896, it was Colonization, colonized by the French colonial empire, French as part of French West Africa; in 1958, Upper Volta became a self-governing colony wi ...

Hybrid Vehicle
A hybrid vehicle is one that uses two or more distinct types of power, such as submarines that use diesel when surfaced and batteries when submerged. Other means to store energy include pressurized fluid in hydraulic hybrids. Hybrid powertrains are designed to switch from one power source to another to maximize both fuel efficiency and energy efficiency. In hybrid electric vehicles, for instance, the electric motor is more efficient at producing torque, or turning power, while the combustion engine is better for maintaining high speed. Improved efficiency, lower emissions, and reduced running costs relative to non-hybrid vehicles are three primary benefits of hybridization. Vehicle types Two-wheeled and cycle-type vehicles Mopeds, electric bicycles, and even electric kick scooters are a simple form of a hybrid, powered by an internal combustion engine or electric motor and the rider's muscles. Early prototype motorcycles in the late 19th century used the same principle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hwair
Hwair (also , , ) is the name of , the Gothic alphabet, Gothic letter expressing the or sound (reflected in English language, English by the inverted ''Wh (digraph), wh''-spelling for ). Hwair is also the name of the Latin ligature (capital ) used to transcribe Gothic. Name The name of the Gothic letter is recorded by Alcuin in Codex Vindobonensis 795 as ''uuaer''. The meaning of the name was probably "cauldron, pot" (cf. ' "skull"); comparative reconstruction shows ("a kind of dish or pot") in Proto-Indo-European. There was no Elder Futhark rune for the phoneme, so that unlike those of most Gothic letters, the name does not continue the name of a rune (but see Qairþra). Sound Gothic ' is the reflex of Common Germanic , which in turn continues the Indo-European Labialized velar consonant, labiovelar after it underwent Grimm's law. The same phoneme in Old English and Old High German is spelled ''hw''. Transliteration The Gothic letter is transliterated with the Latin liga ...

Holcomb Valley Scout Ranch
Located in Los Angeles County, California's San Gabriel Valley, the Boy Scouts of America's San Gabriel Valley Council (#40) was one of five councils serving Los Angeles County. It was headquartered in Pasadena. Greater Los Angeles Area Council (GLAAC) is a new Boy Scouts of America Council made from the merger of the Los Angeles Area Council and the San Gabriel Valley Council. The vote to merge was held on March 21, 2015. The new name for the council, Greater Los Angeles Area Council, was announced on June 11, 2015. The new council centers is in Los Angeles. Due to the large size of the two original councils, the merger was a process which was completed over a time span, and finished in 2017. GLAAC has three Scout shops in Los Angeles, San Pedro and Arcadia. GLAAC operates eight BSA camps in the greater Los Angeles area. History With the founding of the BSA in 1910, the first goal of the San Gabriel Valley Scout leaders was to organize as new troops. Paid professionals, many ...

Vickers Hardness
The Vickers hardness test was developed in 1921 by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter can be used for all materials irrespective of hardness. The basic principle, as with all common measures of hardness, is to observe a material's ability to resist plastic deformation from a standard source. The Vickers test can be used for all metals and has one of the widest scales among hardness tests. The unit of hardness given by the test is known as the Vickers Pyramid Number (HV) or Diamond Pyramid Hardness (DPH). The hardness number can be converted into units of pascals, but should not be confused with pressure, which uses the same units. The hardness number is determined by the load over the surface area of the indentation and no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypervelocity Star
In astronomy, stellar kinematics is the Observational astronomy, observational study or measurement of the kinematics or motions of stars through space. Stellar kinematics encompasses the measurement of stellar Velocity, velocities in the Milky Way and its Satellite galaxies of the Milky Way, satellites as well as the internal kinematics of more distant Galaxy, galaxies. Measurement of the kinematics of stars in different subcomponents of the Milky Way including the thin disk, the thick disk, the Bulge (astronomy), bulge, and the stellar halo provides important information about the formation and evolutionary history of our Galaxy. Kinematic measurements can also identify exotic phenomena such as hypervelocity stars escaping from the Milky Way, which are interpreted as the result of gravitational encounters of binary stars with the Sagittarius A*, supermassive black hole at the Galactic Center. Stellar kinematics is related to but distinct from the subject of stellar dynamics, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haplogroup HV (mtDNA)
Haplogroup HV is a Human mitochondrial DNA haplogroup, human mitochondrial DNA (mtDNA) haplogroup. Origin Haplogroup HV derives from the haplogroup R0 (mtDNA), haplogroup R0, which in turn descends from haplogroup R (mtDNA), haplogroup R. HV is also the ancestral clade to the haplogroups Haplogroup H (mtDNA), H and Haplogroup V (mtDNA), V. A possible origin of HV haplogroup is in the region of Western Iran, Mesopotamia, and the South Caucasus, where the highest prevalence of HV has been found. Distribution Haplogroup HV is found mainly in Western Asia, Central Asia, Southern Europe, Eastern Europe, and North Africa. In Africa, the clade peaks among Egyptians inhabiting El-Hayez oasis (14.3%). with the HV0 subclade occurring among Mozabite people, Mozabite Berbers (8.24%),S5 Table/ref> Libyans (7.4%), Reguibat tribe, Reguibate Sahrawi people, Sahrawi (6.48%), Zenata Berbers (5.48%), and Algerians (4.84% total; 2.15%-3.75% in Oran). In a study published in 2013, haplogroup HV(xHV ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrogen Vehicle
A hydrogen vehicle is a vehicle that uses hydrogen to move. Hydrogen vehicles include some road vehicles, rail vehicles, space rockets, forklifts, ships and aircraft. Motive power is generated by converting the chemical energy of hydrogen to mechanical energy, either by reacting hydrogen with oxygen in a fuel cell to power electric motors or, less commonly, by hydrogen internal combustion. Hydrogen burns cleaner than fuels such as gasoline or methane but is more difficult to store and transport because of the small size of the molecule. As of the 2020s hydrogen light duty vehicles, including passenger cars, have been sold in small numbers due to competition with battery electric vehicles. , there were two models of hydrogen cars publicly available in select markets: the Toyota Mirai (2014–), the first commercially produced dedicated fuel cell electric vehicle (FCEV), and the Hyundai Nexo (2018–). The Honda CR-V e:FCEV became available, for lease only, in very limited q ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kayak
] A kayak is a small, narrow human-powered watercraft typically propelled by means of a long, double-bladed paddle. The word ''kayak'' originates from the Inuktitut word '' qajaq'' (). In British English, the kayak is also considered to be a kind of canoe. There are countless different types of kayaks due to the craft being easily adaptable for different environments and purposes. The traditional kayak has an enclosed deck and one or more cockpits, each seating one occupant or kayaker, differentiating the craft from an open-deck canoe. The cockpit is sometimes covered by a spray deck that prevents unwanted entry of water from waves or splashes. Even within these confines, kayaks vary vastly in respect to materials, length, and width, with some kayaks such as the sprint kayak designed to be fast and light, and others such as the whitewater kayak designed to be sturdy and maneuverable. Some modern paddlecrafts, which still claim the title "kayak", remove integral parts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
