Two major pieces (queens or rooks) can easily force checkmate on the edge of the board. The process is to put the two pieces on adjacent ranks or files and gradually force the king to the side of the board, where one piece keeps the king on the edge of the board while the other delivers checkmate.
Urine is mostly water (about 95% water), however, the rest of the contents of urine can vary depending of what youâve eaten, drank, breathed or been exposed to. The remainder of urine usually consists of urea, uric acid, ammonia, hormones, dead blood cells, proteins, salts and minerals, and toxins.
The sediment you see in urine can be made up of a variety of substances, including sloughing of tissue (debris), crystals, casts, small stones, or cells. Depending on the type of sediment, the cause may vary considerably. The most common cause of sediment in the urine is a urinary tract infection. In this case, the urine will contain cells, especially white blood cells, or pus. This type of sediment typically looks cloudy instead of flaky. The urine may have an odor.
