Lumia imaging apps are imaging applications by Microsoft Mobile and formerly by Nokia for Lumia devices built on the technology of Scalado (except for Lumia Panorama which was developed earlier by Nokia originally for Symbian and MeeGo devices).
 The Lumia imaging applications were notably all branded with "Nokia" in front of their names, but after Microsoft acquired Nokia's devices and services business the Nokia branding was superseded with "Lumia", and often updates included nothing but name changes, but for the Lumia Camera this included a new wide range of feature additions.
 Most of the imaging applications are developed by the Microsoft Lund division.
 As part of the release of Windows 10 Mobile and the integration of Lumia imaging features into the Windows Camera and Microsoft Photos applications some of these applications stopped working in October 2015.

Pre-Indo-European languages are any of several old languages, not necessarily related to one another, that existed in prehistoric Europe and South Asia before the arrival of speakers of Indo-European languages.
 The oldest Indo-European language texts date from 19th century BCE in Kültepe in modern-day Turkey, and while estimates vary widely, spoken Indo-European languages are believed to have developed at the latest by the third millennium BCE (see Proto-Indo-European Urheimat hypotheses).
 Thus the Pre-Indo-European languages must have developed earlier than, or in some cases alongside, the Indo-European languages.
Operation is a battery-operated game of physical skill that tests players' hand-eye coordination and fine motor skills.
 The game's prototype was invented in 1964 by John Spinello, a University of Illinois industrial design student at the time, who sold his rights to the game to Milton Bradley for a sum of USD $500 and the promise of a job upon graduation.
 Initially produced by Milton Bradley in 1965, "Operation" is currently made by Hasbro, with an estimated franchise worth of USD $40 million.
A natural border is a border between states or their subdivisions which is concomitant with natural formations such as rivers, mountain ranges, or deserts.
 The "doctrine of natural boundaries" developed in Western culture in the 17th century being based upon the "natural" ideas of Rousseau and developing concepts of nationalism.
 The similar concept in China developed earlier from natural zones of control.
