Amaterasu
Amaterasu (天照), Amaterasu-ōmikami (天照大神／天照大御神／天照皇大神), or Ōhirume-no-muchi-no-kami (大日孁貴神) is a deity of the Japanese myth cycle and also a major deity of the Shinto religion. She is seen as the goddess of the sun and the universe. The name Amaterasu is derived from Amateru and means "shining in heaven". The meaning of her whole name, Amaterasu-ōmikami, is "the great august kami (deity) who shines in the heaven".[N 1] According to the Kojiki and Nihon Shoki chronicles in Japanese mythology, the Emperors of Japan are considered to be direct descendants of Amaterasu.

Tautomerism Detected by NMR
Tautomerism is typically the relocation of a light atom, often hydrogen, at the same time as a rearrangement of the electronic structure.  Typical examples are acetylacetone and acetone. This entry gives a short introduction to how to detect and describe a tautomeric equilibrium using Nuclear Magnetic Resonance (NMR). Typical parameters used are chemical shifts (1H,13C,15N,19F and 17O) one-bond coupling constants and isotope effects on chemical shifts.

Single Point Mooring (SPM) Systems with Buoys
The SPM system consists of four main components, namely, the body of the buoy, the anchoring and mooring components, the fluid transfer system and the ancillary elements. Static legs linked to the seabed underneath the surface keep the buoy body in place. Above the water level, the body has a spinning portion that is attached to the offloading/loading tanker. A roller bearing, referred to as the main bearing, connects these two portions. Due to this array, the anchored tanker can easily weather-vane around the buoy and find a steady position. The concept of the buoy is determined by the type of bearing utilized and the divide between the rotating and geostatic sections. The buoy’s size is determined by the amount of counter buoyancy required to keep the anchor chains in place, and the chains are determined by environmental conditions and vessel size.

Boarhounds
Boarhounds are hunting dogs bred for hunting wild boar. The most commonly used for this purpose are hounds, dachshunds or terriers, but pointers, spitz or retrievers can also be used. The dog should be courageous, persistent, passionate, disciplined, sharp and obedient. Hunting in this group of dogs can be carried out individually and for such breeds are used small and collective breeds as well as medium and large breeds of dogs.

Positive Impact Organizations
Positive Impact Organizations broaden their purposes and their value creation to embrace strong sustainability, thereby contributing to economic, social, and environmental value. "Positive impact" is defined by products and services that are created with the purpose of solving societal problems. It reflects the shift from reducing an organization’s negative footprint to achieving a significant net positive impact on society and the planet.

Non-Governmental Organisations and Sustainable Community Development
Alternative healthcare, community development, social justice, and education are all areas where non-governmental organisations (NGOs) are increasingly being recognised or promoted, but these efforts are hampered by government inefficiency and resource constraints. However, the statement of non-profit organisations is more complicated than simply comparing them to the government, as they may also suffer from a lack of resources and ineffective management, just like the government. Meanwhile, NGOs are generally defined by four characteristics: they are voluntary, non-partisan, non-profit, and non-criminal. According to Salamon and Anheier, seven distinct characteristics were used to categorise and differentiate NGOs. The seven characteristics are as follows: (1) formal (officially registered and governed); (2) private (having a separate organisation from the government); (3) non-profit distributing (different from the objectives of establishing a business organisation); (4) self-governing (privately managed); (5) voluntary (worked voluntarily); (6) non-religious (not motivated by preaching); and (7) non-political (not involved in promoting candidates in elections). These characteristics are particularly useful for identifying and differentiating NGOs from other organisations.

Drag Polar
The drag polar or drag curve is the relationship between the lift on an aircraft and its drag, expressed in terms of the dependence of the drag coefficient on the lift coefficient. It may be described by an equation or displayed in a diagram called a polar plot.

Starter Cultures in Foods
Starter cultures can be defined as preparations with a large number of cells that include a single type or a mixture of two or more microorganisms that are added to foods in order to take advantage of the compounds or products derived from their metabolism or enzymatic activity.

Onion Dome
An onion dome (Russian: луковичная глава, lúkovichnaya glavá; compare Russian: лук, luk, "onion") is a dome whose shape resembles an onion and is usually associated with Russia n architectural style. Such domes are often larger in diameter than the tholobate upon which they sit, and their height usually exceeds their width. These bulbous structures taper smoothly to a point. It is a typical feature of churches belonging to Russian Orthodox church. Occasionally, there are similar buildings in European countries like in Germany in Bavaria, (German: Zwiebelturm (literally "onion tower") in Austria, the Czech Republic, northeastern Italy, in other Eastern European countries and in Oriental regions like Mughal India, the Middle East and Central Asia. However, the old buildings outside of Russia usually do not have the distinctive typical construction of the Russian onion design. Probably the origin lies in the native architectural style of early Rus' tribes. Other types of Eastern Orthodox cupolas include helmet domes (for example, those of the Assumption Cathedral in Vladimir), Ukrainian pear domes (Saint Sophia Cathedral in Kiev), and Baroque bud domes (St. Andrew's Church in Kiev) or an onion-helmet mixture like the Saint Sophia Cathedral in Novgorod.

400 kV Double-Circuit Transmission Lines
A high-voltage AC double-circuit 400 kV overhead power transmission line runs from the city of Elk (Poland) to the city of Alytus (Lithuania). This international 400 kV power transmission line is potentially one of the strongest magnetic field-generating sources in the area. This 400 kV voltage double-circuit overhead transmission line and its surroundings were analyzed using the mathematical analytical methods of superposition and reflections. This research paper includes the calculation of the numerical values of the magnetic field and its distribution. The research showed that the values of the magnetic field strength near the international 400 kV power transmission line exceed the threshold values permitted by relevant standards. This overhead power line is connected to the general (50 Hz) power system and generates a highly intense magnetic field. It is suggested that experimental trials should be undertaken in order to determine the maximum values of the magnetic field strength. For the purpose of mitigating these values, it is suggested that the height of the support bars should be increased or that any individual and commercial activities near the object under investigation should be restricted.
