Memory consolidation involves the process by which newly acquired information becomes stored in a long-lasting fashion. Evidence acquired over the past several decades, especially from studies using post-training drug administration, indicates that emotional arousal during the consolidation period influences and enhances the strength of the memory and that multiple different chemical signaling ...
Several techniques have been used for sand production control in sandstone reservoirs.The main objective of this research is to present a suitable resin to be used as a consolidation agent in oil reservoirs. To achieve this purpose, urea-formaldehyde resin, phenol-formaldehyde resin, and modified urea-formaldehyde resin were selected to be studied. Core samples were made by the sand sample prov...
this research was performed to determine the efficiency effect of sedimentary environment of kerman city area on soil structure bycomparing natural and reconstituted consolidation curves. in this regard, four different criteria such as sensitivity strength, stresssensitivity, schmertman criteria and the result of the uniaxial compression test were used. the base of these criteria is to compare ...

Cultural heritage protection demands targeted restoration actions in order to increase monuments’ lifetime. Such actions require the use of conservation materials (e.g., consolidation materials), which can increase the durability of historic materials. However, the performance of each material on the restoration phase significantly differs with respect to its type, chemical properties and the b...
recently, a renewed interest arises in the application of nanotechnology for the upstream petroleum industry. in particular, adding nanoparticles to fluids may drastically benefit enhanced oil recovery and improve well drilling, by changing the properties of the fluid, rocks wettability alteration, advanced drag reduction, strengthening the sand consolidation, reducing the inter-facial tension and...
