Box Camera

The box camera is, with the exemption of the pin whole camera, a camera in its simplest form. The classic box camera is formed more or less like a box, hence the name. A box camera has a simple optical organism, often only in the form of a simple meniscus lens. It usually lacks a focusing system as well as control of aperture and secures speeds. This makes it fitting for daylight photography only. In the 1950s, box cameras with photographic flash were introduced, allowing in-door photos.

The modern not reusable camera using 135 film.

Telephone tapping

Telephone tapping or Wire tapping/ Wiretapping (in US) describes the monitoring of telephone conversations by a third party, often by covert means. The Telephone tap or Wire tap received its name because, Iin the past, the monitoring connection was applied to the wires of the telephone line of the person who was being monitored and drew off or tapped a small amount of the electrical signal carrying the conversation.
Legal status
Telephone tapping is formally strictly controlled in many countries to safeguard an individual's privacy; this is the case in all developed democracies. In theory, Telephone tapping often needs to be authorized by a court, and is, again in theory, usually only approved when evidence shows it is not possible to detect criminal or subversive activity in less intrusive ways; often the law and regulations require that the crime investigated must be at least of a certain severity. In practice however, permission for Telephone tapping is easily obtained on a routinely basis without further investigation by the court or other entity granting such permission. Illegal or unauthorised telephone tapping is often a criminal offence.

Mangrove

Mangroves are trees and shrubs that grow in saline coastal habitats. The word is used in at least three senses, most generally to refer to the habitat and entire plant assemblage or mangal , for which the terms mangrove swamp and mangrove forest are also used, to refer to all trees and huge shrubs in the mangal, and narrowly to refer to the mangrove family of plants, the Rhizophoraceae, or even more specially just to mangrove trees of the genus Rhizophora. Mangal is found in depositional coastal environments where fine sediments, often with high organic content, collect in areas protected from high energy wave action.

Rose gold

Rose gold is a gold and copper alloy generally used for specialized jewelry due to its reddish color. It is also identified as pink gold and red gold. Because it was popular in Russia at the beginning of the nineteenth century it is also known as Russian gold, although this term has become somewhat rare.
Since it is an alloy, there is no such thing as "pure rose gold"; pure gold is yellow and pure copper is reddish.
Although the names are often used interchangeably, the dissimilarity between red, rose, and pink gold is the copper content: The higher the copper content, the stronger the red coloration. A common alloy for rose gold is three-quarters gold and one-quarter copper.
Rose gold is also the name of a commonly-used finish in bell interiors of musical instruments. It consists of a very thin plating of copper over a layer of silver. No real gold is used.

Deafness

The word deaf is used in a different way in different contexts, and there is some controversy over its meaning and implications. In scientific and medical terms, deafness normally refers to a physical condition characterized by lack of sensitivity to sound. Notated as deaf with a lowercase d, this refers to the audiological experience of someone who is partly or wholly lacking hearing In legal terms, deafness is defined by degree of hearing loss. These degrees include profound or total deafness (90 dB - 120 dB or more of hearing loss), severe (60 dB - 90 dB), moderate (30 dB - 60 dB), and mild deafness(10 dB - 30 dB of hearing loss). Both severe and moderate deafness can be referred to as partial deafness or as hard of hearing, while mild deafness is usually called hard of hearing.
Within the Deaf community, the term "Deaf" is often capitalized when written, and it refers to a tight-knit cultural group of people whose primary language is signed, and who practice social & cultural norms which are different from those of the surrounding hearing community. This community does not mechanically include all those who are clinically or legally deaf, nor does it exclude every hearing person. According to Baker & Padden, it includes any person or persons who "identifies him/herself as a member of the Deaf community, and other members accept that person as a part of the community"
