The Preparation and Properties of Mammalian Ribonucleic Acids

Description: "A method for the preparation of mammalian ribonucleic acids employing high concentrations of guanidine hydrochloride in the fractionation procedure is reported in this paper. Aside from the facility of preparation the method has the advantage of avoiding conditions of acidity and alkalinity which might degrade tissue ribonucleic acids and, by virtue of the protein denaturant action of guanidine salts, of minimizing the possibility for enzymatic degradation" (p. 3).

The Unified Soil Classification System, Appendix B: Characteristics of Soil Groups Pertaining to Roads and Airfields

Description: Report describing various kinds of soils and their characteristics, for use in constructing roads and airfields: "The properties desired in soils for foundations under roads and airfields and for base courses under flexible pavements are: adequate strength, good compaction characteristics, adequate drainage, resistance to frost action in areas where frost is a factor, and acceptable compression and expansion characteristics. Certain of these properties, if inadequate in the soils available, may be supplied by proper construction methods" (p. B1).
