An experimental study on modification of pervious concrete properties using polyacrylamide [PDF]

Građevinski Materijali i Konstrukcije
This study tends to use polyacrylamide (PAM) as a potential cement replacer for the enhancement of pervious concrete properties. The study considers four different replacement percentages and compares them with a zero-percentage replacement mix.

Denaturing Polyacrylamide Gel Electrophoresis [PDF]

Current Protocols in Nucleic Acid Chemistry, 1994
AbstractThin polyacrylamide gels that contain a high concentration of urea as a denaturant are capable of resolving short (<500 nucleotides) single‐stranded fragments of DNA or RNA that differ in length by as little as one nucleotide. Such gels are uniquely suited for nucleic acid sequence analysis, which is required, for instance, for all ...
