Soil-structure Interface Modelling: Influence of Impregnation
Information on the influence of impregnation of cementitious slurry at the soil-structure interface of bored cast in-situ foundation is inadequate in available literatures. Moreover, influence of such impregnation on negating the detrimental effects of smear zone, formed by construction tools, surrounding the borehole is also unknown. In classical foundation engineering, influences of smear and...
متن کاملResin impregnation of cellulose nanofibril films facilitated by water swelling
Flexible composite films were produced by impregnating aqueous phenol formaldehyde (PF) resin into water-swollen cellulose nanofibril (CNF) films. CNF films were prepared using a pressurized filtration method in combination with freeze drying. The freeze-dried films were swollen with water then impregnated with PF resin by soaking in aqueous resin solutions of varying concentrations. Small amou...
متن کاملThe application of a resin impregnation technique to dentin using a vacuum
Background: There is a technique in the industry called resin procedures like resin coating. For example, epoxy resin is injected to repair cracks in concrete of 0.2 mm or larger. In addition, a casting product can be strengthened when resin is injected to fill in a blowhole. A vacuum can be utilized to allow the resin to penetrate into every corner. In this study, we investigate whether bondin...
متن کاملBalamuthia mandrillaris from soil samples.
Balamuthia mandrillaris amoebas are recognized as a causative agent of granulomatous amoebic encephalitis, a disease that is usually fatal. They were first recognized when isolated from the brain of a mandrill baboon that died in the San Diego Zoo Wild Life Animal Park. Subsequently, the amoebas have been found in a variety of animals, including humans (young and old, immunocompromised and immu...
متن کاملTooth strengthening for autologous tooth crown transplants using an industrial resin impregnation method
The purpose of this study was to investigate if it was possible to strengthen a tooth for autologous tooth crown transplant by using the resin impregnation method already used for industrial purposes. Eightyfour upper first premolar tooth crowns were divided into three groups (n=28 each) to be kept either wet, dry for one day, or dry for one week. In addition, within each group, the teeth were ...
