Buddhist Ethics
Buddhist ethics are traditionally based on what Buddhists view as the enlightened perspective of the Buddha, or other enlightened beings such as Bodhisattvas. The Indian term for ethics or morality used in Buddhism is Śīla or sīla (Pāli). Śīla in Buddhism is one of three sections of the Noble Eightfold Path, and is a code of conduct that embraces a commitment to harmony and self-restraint with the principal motivation being nonviolence, or freedom from causing harm. It has been variously described as virtue, moral discipline and precept. Sīla is an internal, aware, and intentional ethical behavior, according to one's commitment to the path of liberation. It is an ethical compass within self and relationships, rather than what is associated with the English word "morality" (i.e., obedience, a sense of obligation, and external constraint). Sīla is one of the three practices foundational to Buddhism and the non-sectarian Vipassana movement — sīla, samādhi, and paññā as well as the Theravadin foundations of sīla, Dāna, and Bhavana. It is also the second pāramitā. Sīla is also wholehearted commitment to what is wholesome. Two aspects of sīla are essential to the training: right "performance" (caritta), and right "avoidance" (varitta). Honoring the precepts of sīla is considered a "great gift" (mahadana) to others, because it creates an atmosphere of trust, respect, and security. It means the practitioner poses no threat to another person's life, property, family, rights, or well-being. Moral instructions are included in Buddhist scriptures or handed down through tradition. Most scholars of Buddhist ethics thus rely on the examination of Buddhist scriptures, and the use of anthropological evidence from traditional Buddhist societies, to justify claims about the nature of Buddhist ethics.

Kingdom
In biology, a kingdom (Latin: regnum, plural regna) is the second highest taxonomic rank, just below domain. Kingdoms are divided into smaller groups called phyla. Traditionally, some textbooks from the United States and Canada used a system of six kingdoms (Animalia, Plantae, Fungi, Protista, Archaea/Archaebacteria, and Bacteria/Eubacteria) while textbooks in Great Britain, India, Greece, Brazil and other countries use five kingdoms only (Animalia, Plantae, Fungi, Protista and Monera). Some recent classifications based on modern cladistics have explicitly abandoned the term kingdom, noting that some traditional kingdoms are not monophyletic, meaning that they do not consist of all the descendants of a common ancestor. The terms flora (for plants), fauna (for animals), and, in the 21st century, funga (for fungi) are also used for life present in a particular region or time.

Middle East Respiratory Syndrome Coronavirus
The Middle East respiratory syndrome-related coronavirus (MERS-CoV), or EMC/2012 (HCoV-EMC/2012), is a novel positive-sense, single-stranded RNA virus of the genus Betacoronavirus. Initially called novel coronavirus 2012 or simply novel coronavirus, it was first reported in 2012 after genome sequencing of a virus isolated from sputum samples from a person who fell ill in a 2012 outbreak of a new flu. As of July 2015, MERS-CoV cases have been reported in over 21 countries, including Saudi Arabia, Jordan, Qatar, Egypt, the United Arab Emirates, Kuwait, Turkey, Oman, Algeria, Bangladesh, Indonesia (none were confirmed), Austria, the United Kingdom, South Korea, the United States, Mainland China, Thailand, and the Philippines. MERS-CoV is one of several viruses identified by WHO as a likely cause of a future epidemic. They list it for urgent research and development.

List of Minerals H (Complete)
This list includes those recognised minerals beginning with the letter H. The International Mineralogical Association is the international group that recognises new minerals and new mineral names, however minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date. This list contains a mixture of mineral names that have been approved since 1959 and those mineral names believed to still refer to valid mineral species (these are called "grandfathered" species). The data was exported from mindat.org on 29 April 2005; updated up to 'IMA2018'. The minerals are sorted by name, followed by the structural group (rruff.info/ima and ima-cnmnc by mineralienatlas.de, mainly) or chemical class (mindat.org and basics), the year of publication (if it's before of an IMA approval procedure), the IMA approval and the Nickel–Strunz code. The first link is to mindat.org, the second link is to webmineral.com, and the third is to the Handbook of Mineralogy (Mineralogical Society of America).

List of Railway Electrification Systems
This is a list of the power supply systems that are, or have been, used for tramway and railway electrification systems. Note that the voltages are nominal and vary depending on load and distance from the substation. Many modern trams and trains use on-board solid-state electronics to convert these supplies to run three-phase AC induction motors. Tram electrification systems are listed here.

Romney Family
The Romney family, prominent in U.S. politics and other professions, is most known for its connection with George W. Romney (1907 in Colonia Dublán, Galeana, Chihuahua, Mexico – 1995 at Bloomfield Hills, Michigan), 43rd governor of Michigan (1963–1969) and his son, Mitt Romney (born 1947 in Detroit, Michigan), 70th governor of Massachusetts (2003–2007), and Republican nominee for the presidency of the United States in 2012. George Romney's father was Gaskell Romney (1871 in St. George, Utah – 1955 in Salt Lake City, Utah), and his mother was Anna Amelia Pratt. Anna's grandfather was renowned early Mormon leader Parley Parker Pratt. Based upon the family's heritage going back to the first Mormon generation and to their modern-day prominence in business, politics, and as part of The Church of Jesus Christ of Latter-day Saints, authors Richard and Joan Ostling have written variously that the Romneys are "an LDS political dynasty" and that "The Romneys are LDS royalty." The family is linked by marriage to the Smith family, and has a lateral relationship with the Matheson family, the Huntsman family, and the Eyring family. A branch of the Romneys reside in the Mormon colonies in Mexico. The Romney family emigrated to the United States from Dalton-in-Furness, England in the 1840s.

Nickel Allergy
Nickel allergy or nickel allergic contact dermatitis (Ni-ACD) is a form of allergic contact dermatitis (ACD) caused by exposure to the chemical element nickel. It typically causes a rash that is red and itchy and that may be bumpy or scaly. The main treatment is avoiding contact with nickel-releasing metals, such as wearing inexpensive jewelry.

Pluteus Larva
An echinoderm (/ɪˈkaɪnəˌdɜːrm, ˈɛkə-/) is any member of the phylum Echinodermata (/ɪˌkaɪnoʊˈdɜːrmətə/). The adults are recognisable by their (usually five-point) radial symmetry, and include starfish, brittle stars, sea urchins, sand dollars, and sea cucumbers, as well as the sea lilies or "stone lilies". Adult echinoderms are found on the sea bed at every ocean depth, from the intertidal zone to the abyssal zone. The phylum contains about 7,000 living species, making it the second-largest grouping of deuterostomes, after the chordates. Echinoderms are the largest entirely marine phylum. The first definitive echinoderms appeared near the start of the Cambrian. The echinoderms are important both ecologically and geologically. Ecologically, there are few other groupings so abundant in the biotic desert of the deep sea, as well as shallower oceans. Most echinoderms are able to reproduce asexually and regenerate tissue, organs, and limbs; in some cases, they can undergo complete regeneration from a single limb. Geologically, the value of echinoderms is in their ossified skeletons, which are major contributors to many limestone formations, and can provide valuable clues as to the geological environment. They were the most used species in regenerative research in the 19th and 20th centuries. Further, some scientists hold that the radiation of echinoderms was responsible for the Mesozoic Marine Revolution.
