Structural quality of polyacrylamide-treated cohesive soils in the coastal tablelands of Pernambuco - SciELO
The low agricultural potential of the soils of the coastal tablelands region of Pernambuco is related to the presence of cohesive layers (Giarola & Silva, 2002; Lima et al., 2005), which have crop-growth-limiting physical and hydro-physical

Genetic diversity of Piracanjuba populations in fish stocking programs in the Tietê River, Brazil - SciELO
High heterozygosity rates in the three populations (SA: average 0.724; SB: 0.686; NP: 0.692) and nonsignificant HWE revealed an adequate intrapopulation genetic variability. The Shannon Index showed a similar trend of high genetic diversity

- Do polyacrylamide-type polymers have good thermal stability?
- Polyacrylamide-type polymers with good thermal stability present good long-term stability at high temperature and high salinity conditions. Viscosity reduction of polyacrylamide-type polymers with good thermal stability was owing to polymer main chain degradation at harsh conditions.
- What is thermal stability of water soluble polyacrylamide (PAM) and partially hydrolyzed polymers?
- Thermal stability of water-soluble polyacrylamide (PAM) and partially hydrolyzed polyacrylamide (HPAM) polymers under various solution conditions have been studied utilizing Quantum Mechanics Density Functional Theory (DFT) computational modeling method.
- How to predict long-term stability of polyacrylamide-type polymer under high temperature and salinity?
- A facile model was developed by TGA method for long-term stability prediction of polyacrylamide-type polymer under high temperature and high salinity conditions. Polyacrylamide-type polymers with good thermal stability present good long-term stability at high temperature and high salinity conditions.
- Why are polyacrylamide-type polymers limited to high temperature and salinity?
- However, many polyacrylamide-type polymers are limited for reservoirs with high temperature (above 90 ℃) and high salinity (above 50,000 ppm), as they are susceptible to losing viscosity due to chemical and thermal degradation in aqueous environment , , , .
