This compilation of data is called a tide table. Tides have little effect in the open ocean and in lakes, so tables mainly are generated for coastal areas, inlets, bays and estuaries. Not surprisingly, boats rely heavily on tidal information.
nidus in Medicine. nidus niÂ·dus (nÄ«'dÉs) n. pl. niÂ·dusÂ·es or niÂ·di (-dÄ«) A central point or focus of bacterial growth in a living organism. A nest, especially one for the eggs of insects, spiders, pathogenic organisms, or small animals. A cavity where spores develop. A point or place at which something originates, accumulates, or develops, as the center around which calculi form.
How do AVMs cause problems. First is bleeding â the vessels which make up the nidus are fragile and can rupture, which results in bleeding into the brain. Arteries which feed the AVM over time can form aneurysms (weakness in arterial wall which leads to bulging) which can rupture as well.
