How can a tin be opened if it contains not tinned goods but explosives? Or a shell or something no less dangerous, for instance, a retired nuclear reactor?
Certainly, metal can be cut up mechanically, but this is very dangerous. Torch flame or laser beam do not suit the purpose even more so. However, a sheet of water released at high pressure, particularly if additionally saturated with a stream of frozen drops, would probably suit. The researchers from the Tula State University are sure of that.
They suggest that morally and physically obsolete ammunition should be reclaimed in this particular way – the casing should be cut up and explosives should be washed out. In their opinion, this is the safest way, also from the ecological point of view, to separate metal from nitrocompounds - explosive and powder. Information about that is contained in the advanced research database maintained by the International Science and Technology Center.

Scientists at the University of California, Los Angeles present new research on a curious cosmic phenomenon known as "whistlers" -- very low frequency packets...
Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.
When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...
Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur
What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...
