Self-destruct
A self-destruct is a mechanism that can cause an object to destroy itself or render itself inoperable after a predefined set of circumstances has occurred. Self-destruct mechanisms are typically found on devices and systems where malfunction could endanger large numbers of people. Uses Land mines Some types of modern land mines are designed to self-destruct, or chemically render themselves inert after a period of weeks or months to reduce the likelihood of friendly casualties during the conflict or civilian casualties after the conflict's end. The Amended Protocol II to the Convention on Certain Conventional Weapons (CCW), amended in 1996, requires that anti-personnel land mines deactivate and self-destruct, and sets standards for both. Landmines currently used by the United States military are designed to self-destruct after between 4 hours and 15 days depending upon the type. The landmines have a battery and when the battery dies, the land mine self-destructs. The self-des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Social Media Platform
Social media are interactive media technologies that facilitate the creation and sharing of information, ideas, interests, and other forms of expression through virtual communities and networks. While challenges to the definition of ''social media'' arise due to the variety of stand-alone and built-in social media services currently available, there are some common features: # Social media are interactive Web 2.0 Internet-based applications. # User-generated content—such as text posts or comments, digital photos or videos, and data generated through all online interactions—is the lifeblood of social media. # Users create service-specific profiles for the website or app that are designed and maintained by the social media organization. # Social media helps the development of online social networks by connecting a user's profile with those of other individuals or groups. The term ''social'' in regard to media suggests that platforms are user-centric and enable communal acti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Starship
A starship, starcraft, or interstellar spacecraft is a theoretical spacecraft designed for traveling between planetary systems. The term is mostly found in science fiction. Reference to a "star-ship" appears as early as 1882 in '' Oahspe: A New Bible''. While NASA's ''Voyager'' and ''Pioneer'' probes have traveled into local interstellar space, the purpose of these uncrewed craft was specifically interplanetary, and they are not predicted to reach another star system (although ''Voyager 1'' will travel to within 1.7 light years of Gliese 445 in approximately 40,000 years). Several preliminary designs for starships have been undertaken through exploratory engineering, using feasibility studies with modern technology or technology thought likely to be available in the near future. In April 2016, scientists announced Breakthrough Starshot, a Breakthrough Initiatives program, to develop a proof-of-concept fleet of small centimeter-sized light sail spacecraft named ''StarCh ...

Military Base
A military base is a facility directly owned and operated by or for the military or one of its branches that shelters military equipment and personnel, and facilitates training and operations. A military base always provides accommodations for one or more units, but it may also be used as a command center, training ground or proving ground. In most cases, military bases rely on outside help to operate. However, certain complex bases are able to endure on their own for long periods because they are able to provide food, water and other necessities for their inhabitants while under siege. Bases for military aviation are called military air bases, or simply "air bases". Bases for military ships are called naval bases. The environmental impact of a given military base is dependent on its size and the manner of operation conducted at the base. Commonly, habitat destruction, reductions in soil quality, chemical contamination, and noise pollution are among the environmental da ...
