โœฆ Synopsis


Electrophoresis as an Aid to Preparative Ultracentrifugation.--THOMAS J. DIETZ. (Physico-Chemical Department of the Biochemical Research Foundation of the Franklin Institute, Philadelphia, Pa.) The field of protein chemistry has been extended materially by the development of the analytical ultracentrifuge. This apparatus makes possible the subjection of protein solutions to centrifugal force sufficiently intense to cause the protein in solution to sediment, and permits the observation and recording of this sedimentation under controlled conditions by means of a suitable optical system. In consequence of ultracentrifuge studies, many proteins are now regarded as possessing characteristic sedimentation constants (for details see "The Ultra-Centrifuge and the Study of High Molecular Weight Compounds," by

The detailed description, analysis, and interpretation of field stratigraphy is fundamental to archaeological site interpretation. Investigation of morphology at the macro level can be supplemented by examination under the microscope of soil thin sections prepared from undisturbed samples. Until rec
