Latent prints are not readily visible to the naked eye. As a result, these hidden prints must be developed in some way to increase their visibility and contrast. The most common method of developing latent prints on nonporous objects is to physically enhance them by applying fingerprint powder.
The Crystal Ball by John William Waterhouse (1902, oil on canvas). Scrying (also called seeing or peeping) is the practice of looking into a translucent ball or other material with the belief that things can be seen, such as spiritual visions, and less often for purposes of divination or fortune-telling.ne method of scrying using a crystal ball involves a self-induced trance. Initially, the medium serves as a focus for the attention, removing unwanted thoughts from the mind in the same way as a mantra. Once this stage is achieved, the scryer begins a free association with the perceived images suggested.
thrashing-Computer Definition. In a virtual memory system, it is the excessive swapping of pages of data between memory and the hard disk, causing the application to respond more slowly. The virtual memory function tracks page usage and keeps often-used pages in memory as much as possible. However, the more applications that are kept open in computers with limited memory, the more thrashing occurs. For an explanation of the paging operation, see virtual memory. Poor program design may also contribute to thrashing.
