Dyschezia and Hematochezia in Cats. Dyschezia is a condition in which defecation is extremely difficult or painful, and hematochezia is symptomized by bright red blood in the stool. Both conditions are visible symptoms of an underlying disease that causes inflammation or irritation of the rectum or anus. Hematochezia can also be concurrent with diseases of the colon.
Introduction to Upright Pianos. The first square shaped piano was invented by Frederici of Gera, followed shortly by Johannes Zumpe. In the nineteenth century, John Isaac Hawkins of Philadelphia developed the upright piano and the iron frame. This frame could hold the tension of thicker strings, giving the piano a bigger, richer sound. Upright pianos come in many sizes. The Spinet Piano was first produced around 1935.
On the piano, the quintessential tonal instrument, the octave is divided into 12 equal semitones represented by the seven white and five black keys. But consider the zoomoozophone, invented in 1978 by Dean Drummond, a founder of New York's Newband. It which resembles a marimba but is 20 feet long and flexible, the octave is divided into 31 parts and thus is capable of producing many more subleties of pitch variation than the piano.
