QUES: Bitumen was used in early photographic technology. In 1826 or 1827, it was used by French scientist Joseph Nicephore Niepce to make the oldest surviving photograph from nature. The bitumen was thinly coated onto a pewter plate which was then exposed in a camera. Exposure to light hardened the bitumen and made it insoluble, so that when it was subsequently rinsed with a solvent only the sufficiently light-struck areas remained. Many hours of exposure in the camera were required, making bitumen impractical for ordinary photography, but from the 1850s to the 1920s it was in common use as a photoresist in the production of printing plates for various photomechanical printing processes.[not in citation given]

QUES: Canon law is the body of laws and regulations made by ecclesiastical authority (Church leadership), for the government of a Christian organization or church and its members. It is the internal ecclesiastical law governing the Catholic Church (both Latin Church and Eastern Catholic Churches), the Eastern and Oriental Orthodox churches, and the individual national churches within the Anglican Communion. The way that such church law is legislated, interpreted and at times adjudicated varies widely among these three bodies of churches. In all three traditions, a canon was originally a rule adopted by a church council; these canons formed the foundation of canon law.

QUES: Many other databases have application software that accesses the database on behalf of end-users, without exposing the DBMS interface directly. Application programmers may use a wire protocol directly, or more likely through an application programming interface. Database designers and database administrators interact with the DBMS through dedicated interfaces to build and maintain the applications' databases, and thus need some more knowledge and understanding about how DBMSs operate and the DBMSs' external interfaces and tuning parameters.

QUES: The Anglo-Saxons formed a new, larger, settlement across the Itchen centred on what is now the St Mary's area of the city. The settlement was known as Hamwic, which evolved into Hamtun and then Hampton. Archaeological excavations of this site have uncovered one of the best collections of Saxon artefacts in Europe. It is from this town that the county of Hampshire gets its name.
