Endovascular Cure of a Locked-In Patient

We report the case of a 60 year-old right-handed gentleman who became acutely “Locked-In” several days after a lower extremity orthopedic procedure. He underwent emergent endovascular treatment and had complete resolution of his neurologic findings except for mild dysarthria and dysphagia. Endovascular intervention for posterior circulation thrombosis is highly effective when patients are treated within 24 hours

Digitizing Products Towards Platforms: The Case of Vehicle Motion System

The development of digital product platforms is a prevailing trend in many industries. As firms incorporate digital technologies into established product categories, they need to manage tensions on multiple organizational layers including strategy, technology and structure. Recent findings suggest that tensions are most likely to be managed by creating resource and coordination flexibility. This paper reports a longitudinal case study of developing a digital product platform. By drawing on organizational ambidexterity theory, we identify four mechanisms—re-scripting, centralizing-re-directing and decoupling—through which the firm creates resource and coordination flexibility. The resulting resource and coordination flexibility in turn lead to the transformation of the firm’s strategy, technology and internal structure. The contribution of this study is in adopting an internal perspective and a bottom-up approach which help to theorize the evolution of digitized products into digital product platforms in an emergent way

Performance of Preload on Cohesionless Soils

Common occurrence of loose normally consolidated fine sands and silts extending to considerable depths necessitates the utilization of ground improvement techniques along the coasts of Arabian Peninsula. In the case considered, the soil profile consisted of twenty meter thick compressible sands, and preloading technique was suggested to stabilize the foundation soil. The paper presents the performance of the preloading and the level of soil improvement achieved. The observed settlements and settlement-time behaviour are compared with the values estimated from various methods. The soil parameters back calculated from measured field behaviour are reported

Foundation Failures Associated with Salt Rock and Surrounding Coastal Plain

A detailed investigation has been conducted to study the causes of severe and widespread damages in a town situated on a salt dome. The study includes a thorough assessment of ground conditions in the coastal plain surrounding the salt dome for possible utilization of the plain as redevelopment areas. Major geological features in the study area comprised of collapsible windblown sands which are underlain by salt rock in the old town and soft/loose sabkha deposits in the proposed redevelopment zones. It has been found that the extensive damages in the buildings and roads are primarily due to subsidence phenomenon associated with the dissolution of salt rock. The properties of the sabkha sediments and anticipated geotechnical problems have been described
