Conflict-of-interest (COI) editing on Wikipedia refers to the situation where individuals edit articles about themselves, their organizations, or topics in which they have a personal stake or significant interest. This is considered problematic because it can lead to biased or unethical edits that do not adhere to Wikipedia's principles of neutrality and verifiability. Wikipedia encourages editors to disclose their conflicts of interest, rather than editing from a biased perspective.

Wikimedia censorship in mainland China refers to the restrictions imposed by the Chinese government on access to Wikimedia projects, including Wikipedia and Wikimedia Commons. This censorship is part of the broader internet censorship regime in China, commonly referred to as the "Great Firewall." Here are some key points about Wikimedia censorship in mainland China: 1. **Blocking of Sites**: Wikipedia, along with other Wikimedia projects, has been intermittently blocked in China.

The Hillsborough disaster refers to a tragic event that occurred on April 15, 1989, at Hillsborough Stadium in Sheffield, England. It was a human crush during an FA Cup semi-final match between Liverpool and Nottingham Forest, resulting in the deaths of 97 Liverpool supporters and injuries to hundreds of others. The disaster is one of the worst sporting tragedies in British history.

An icemaker, or ice maker, is a device that produces ice, either in a refrigerator or as a standalone appliance. There are several types of icemakers: 1. **Built-in Ice Makers**: These are often integrated into refrigerators or freezers. They can produce ice automatically and store it in a dedicated bin. They usually use a water line connected to the household plumbing.

An air ionizer is a device that uses high-voltage electricity to produce negative ions, which are molecules that have gained an extra electron. These negative ions can attach to positively charged particles in the air, such as dust, pollen, smoke, and other pollutants, causing them to clump together and fall to the ground or be attracted to surfaces. The primary purpose of an air ionizer is to improve indoor air quality by reducing airborne contaminants.

In category theory, a **cyclic category** typically refers to a category that captures the idea of cycles or circular structures. It can be viewed as a specialized type of category that includes objects and morphisms that relate to cyclical processes or relationships.

In the context of Christian literature, it often pertains to sermons or explanations of biblical texts that were intended for clergy or laypeople to better understand passages of the Bible.

The Kan-Thurston theorem is a result in the field of topology and geometric group theory, particularly concerning the relationships between 3-manifolds and the algebraic properties of groups. More specifically, it is related to the conjecture regarding the recognition of certain types of 3-manifolds and the structures of groups that can be associated with them.
