Removal and Recovery of Cr(VI) from Polluted Ground Waters: a Comparative Study of Ion-exchange Technologies
The focus of this work has been the study of Cr(VI) removal from ground waters and the simultaneous concentration for its reuse using three different technological alternatives: anion-exchange resins, liquid-liquid extraction assisted by hollow fibre membranes and emulsion pertraction. The viability of the considered objectives, i.e., Cr(VI) separation (<0.5 g/m3) and concentration for reuse (>20,000 g/m3) has been checked and a comparative analysis of the three technologies has been performed. Although the flexibility and ease of operation of non-dispersive solvent extraction, anion-exchange resins and emulsion pertraction lead to higher velocities of chromium removal, yet still maintaining similar concentration efficiencies.
The Challenge of Changing Roles and Improving Surgical Care Now: Crew Resource Management Approach
Many surgeons are also pilots; the two activities demand similar skill sets. Surgeons have developed an interest in aviation models for managing risk and reducing adverse events, such as Crew Resource Management training. This article provides seven suggestions from aviators that might be adopted by surgeons in an effort to improve surgical care and mitigate patient harm. Each suggestion is offered based on the value added to aviation, with an acknowledgment that the suggestion may be more or less applicable in surgery. The suggestions for dealing with the changing roles for surgeons are: Crew Resource Management-type training to improve teamwork should be required for hospital credentialing, surgeons should brief the operating room team before an operation, surgeons should write standards specific to their organization, surgeons should recognize fatigue and age as factors in performance, surgeons should have "check-rides" as a part of the credentialing process, surgeons should abandon the mortality and morbidity conference in favor of a data collection system that effectively examines adverse events for root causes of error, and all members of the surgical team should be subject to mandatory, random drug testing.
