Additionally, marble and limestone can be scratched more easily than harder stones such as granite. Marble is, however, sometimes used in the kitchen as a pastry slab; its perfectly smooth, cool surface is ideal for rolling out dough and piecrusts.ike marble, polished limestone is subject to surface changes or damage from kitchen acids including citrus juices, vinegars, mustards, and so forth. Unsealed, some of the more porous limestones can be subject to stains.
Patient Forums. Your doctor has just ordered a test called an EMG. EMG stands for Electromyogram which loosely translated means electrical testing of muscles but in fact has come to mean electrical testing of nerves and muscles. The EMG is performed by a specialist, the Electromyographer, who is usually a Neurologist or a Physiatrist.
Electromyography (EMG) is an electrodiagnostic medicine technique for evaluating and recording the electrical activity produced by skeletal muscles.EMG is performed using an instrument called an electromyograph, to produce a record called an electromyogram.An electromyograph detects the electrical potential generated by muscle cells when these cells are electrically or neurologically activated.easured EMG potentials range between less than 50 Î¼V and up to 20 to 30 mV, depending on the muscle under observation. Typical repetition rate of muscle motor unit firing is about 7â20 Hz, depending on the size of the muscle (eye muscles versus seat (gluteal) muscles), previous axonal damage and other factors.
