Microbially induced carbonate precipitation is a promising ground improvement technique which can enhance the mechanical properties of soils through calcium carbonate. Experimental evidences indicate that precipitated display different distribution patterns. Crystals develop at grain–grain contacts (contact cementing), connect soil grains were initially not in contact with each other (bridging)...

We performed 83 consecutive cemented revision total hip arthroplasties in 77 patients between 1977 and 1983 using improved cementing techniques. One patient (two hips) was lost to follow-up. The remaining 76 patients (81 hips) had an average age at revision of 63.7 years (23 to 89). At the final follow-up 18 hips (22%) had had a reoperation, two (2.5%) for sepsis, three (4%) for dislocation and...

Available technical methods do not permit the fabri­ cation of dental restorations outside the mouth which will not expose the cementing medium to the influence of the oral fluids. Although meticulous craftsmanship may attain very high standards of marginal adap­ tation in such restorations the solubility and disinte­ gration of cementing media is still considered suffi­ ciently important to wa...

A comprehensive analysis of various types of cementing media used to cement various dental restorations such as crowns, bridges etc. are presented. Effects of various cementing media on the retention of dental post in the root canal have been estimated. The system is mainly consists of strain gauges mounted on a cantilever, a specially design amplifier, data acquisition system (ADC0809), Micro-...

Total elbow arthroplasty (TEA) has changed considerably in the past three decades. Based on the good long-term results with TEA in patients with rheumatoid arthritis, the indications expanded to include management of acute traumatic and posttraumatic conditions in young, higher-demand patients. Today, unlinked, linked semiconstrained, and convertible devices are available. The high complication...
