Abstract: A method for analyzing a spectral signature of a compound specimen is provided. The method includes illuminating a compound specimen with a light in a predetermined spectrum; obtaining a spectral signature of the compound specimen, the spectral signature including at least one light property of a plurality of wavelengths in the spectrum transmitted through the compound specimen; extracting characterizing features of the spectral signature, the characterizing features being light properties of predetermined wavelengths within the spectrum; and comparing the characterizing features with corresponding features stored in a database, the corresponding features are corresponding properties of an expected spectral signature of a specimen including an examined substance.

Abstract: A portable water filtering container having a solid-particle removing filter inside the container and sodium hypochlorite to destroy bacteria in non-potable water is provided.

Abstract: There is provided genetically engineered bovine interferon of the IFN-.alpha.-type and various sub-types thereof. There is further provided a double stranded DNA molecule which includes DNA encoding BoIFN-.alpha. A, BoIFN0.alpha. B, BoIFN-.alpha. C, and BoIFN-.alpha. D, and cloning vehicles including such DNAs. There are further provided cells including such DNA and a process for the production of such types of BoIFN based on the use of such cells. Furthermore, there is also provided a method for the identification of a bovine IFN-.alpha. DNA sequence.
