Hydrodemolition (also known as hydro demolition, hydroblasting, hydro blasting, hydromilling, waterblasting, and waterjetting) is a concrete removal technique which utilizes high-pressure water, often containing an abrasive material, to remove deteriorated and sound concrete as well as asphalt and grout. This process provides an excellent ...
The examination of surfaces give clues as to how tools were made. Typical design techniques include: fracturing, pecking or polishing. Sometimes, stone tools are continually modified and keen attention to surfaces is necessary to recognize each stage of the manufacture process.

The two dimensions that proteins are separated into using this technique can be isoelectric point, protein complex mass in the native state, or protein mass. [citation needed] The separation by isoelectric point is called isoelectric focusing. Thereby, a pH gradient is applied to a gel and an electric potential is applied across the gel, making ...
Laboratory quality control is designed to detect, reduce, and correct deficiencies in a laboratory's internal analytical process prior to the release of patient results, in order to improve the quality of the results reported by the laboratory.
Modern simultaneous CHNS combustion analyzer. Elemental analysis is a process where a sample of some material (e.g., soil, waste or drinking water, bodily fluids, minerals, chemical compounds) is analyzed for its elemental and sometimes isotopic composition.
Rock core samples, the product of a diamond rig.A pied butcherbird perches nearby.. A core sample is a cylindrical section of (usually) a naturally-occurring substance. Most core samples are obtained by drilling with special drills into the substance, such as sediment or rock, with a hollow steel tube, called a core drill.
The technique is often used for the analysis of polymers. As a technique, SEC was first developed in 1955 by Lathe and Ruthven. [ 2 ] The term gel permeation chromatography can be traced back to J.C. Moore of the Dow Chemical Company who investigated the technique in 1964. [ 3 ]
An electropherogram (also called electrophoretogram, sequencing chromatogram, EPG, and e-gram) is a record or chart produced when electrophoresis is used in an analytical technique, primarily in the fields of forensic biology, molecular biology, and biochemistry. [1]
