anine with cytosine. The specific bonds are believed to be the molecular basis of information transfer in nucleic acids. Much work has been done to find the basis of this specificity by the use of synthetic poly-and oligonucleotides and single base derivatives. Some infrared (1~8) and proton magneti

Samuel Kadouryrent values of ranging between 6.5 and 30 mmol/1 show that the lime concentration in solution is the parameter which determines the main characteristics of the reaction and products. The stoichiometry of C.S hydration products vanes with lime concentration in the same way as synthetic C-S-H un

Tomaž Vrtoveces of these materials are such that on heating from the solid to the isotropic liquid state, phase transitions occur with the formation of one or more intermediate anisotropic liquids. The unique and sometimes startling properties of these liquid crystals are the properties of pure compounds. Howeve
