Hydrogel composed of potassium acrylate, acrylamide, and mineral as soil condit...
Costa,Mirian Cristina Gomes; Freire,Alcione Guimarães; Lourenço,Diego Vasconcelos; Sousa,Rayane Rodrigues de; Feitosa,Judith Pessoa de AndradeABSTRACT Hydrogels have potential as soil conditioners due to their high capacity to retain water and mitigate soil salinity. However, investigations under saline conditions are necessary because there are losses in both water absorption and salinity mitigation depending on the composition of hydrogel and ions involved in salinity. In this work, we studied a commercial hydrogel in two experiments. The first exp...
Biocompatibility and biodegradation analysis of Nile Tilapia gelatin and apatit...
Sousa,Efigênia Maria de; Melo,Edla Freire de; Ribeiro,Hálisson Lucas; Feitosa,Judith Pessoa de Andrade; Souza-Filho,Men de Sá Moreira deABSTRACT Fish farming by-products could represent large-scale raw materials for xenogeneic implants that could be used for bone regeneration. The objective of this research was to analyze the biocompatibility and biodegradation of gelatin (G) and apatite (A) membranes from Nile tilapia. Adult male Swiss mice underwent subcutaneous implantation of biocomposites derived from skins and scales in different concentr...
Caesalpinia pulcherrima seed galactomannan on rheological properties of dairy d...
Medeiros,Stella Regina Arcanjo; Oliveira,Victor Alves de; Oliveira,Amanda Mazza Cruz de; Araujo,Marjory Lima Holanda; Feitosa,Judith Pessoa de AndradeABSTRACT: Dairy desserts containing Caesalpinia pulcherrima seed galactomannan were evaluated to determine their static and dynamic rheological behaviors. Variations in consistency index (k), flow behavior (n), yield stress and thixotropy of the desserts indicated that the galactomannan caused an increase in the shear stress and apparent viscosity of the system. All samples exhibited shear-thinning behavior wit...
