Food and drink prohibitions In Argentina and other Spanish language countries bull's testicles are served as "huevos de toro" or 'bull's eggs'. In some regions, such as the European Union, brains and other organs which can transmit bovine spongiform encephalopathy ("mad cow disease") and similar diseases have now been banned from the food chain as specified risk materials. Although eating the stomach of a goat, cow, sheep, or buffalo might be taboo, ancient cheesemaking techniques utilize stomachs (which contain rennet) for turning milk into cheese, a potentially taboo process. Newer techniques for making cheese include a chemical process with artificial rennet. This means that
En echelon veins En echelon veins In structural geology, en échelon veins or "en échelon gash fractures" are structures within rock caused by noncoaxial shear. They appear as sets of short, parallel, planar, mineral-filled lenses within a body of a rock. They originate as tension fractures that are parallel to the major stress orientation, σ, in a shear zone. They are subsequently filled by precipitation of a mineral, typically quartz or calcite. As soon as they form, they begin to rotate in the shear zone. Subsequent growth of the fracture therefore causes the vein to take on a sigmoidal shape. They can be
