in this study. Others have reviewed professionalism issues related to computer and social media use.12,13 In summary, anesthesia providers spent sizable portions of case time performing non–record-keeping applications on AIMS workstations. This use, however, was not independently associated with greater hemodynamic variability or aberrancies in patients during maintenance of general anesthesia ...
متن کاملApparatus for low temperature thermal desorption spectroscopy of portable samples.
An experimental setup for low temperature thermal desorption spectroscopy (TDS) integrated in an ultrahigh vacuum-chamber housing a high-end scanning probe microscope for comprehensive multi-tool surface science analysis is described. This setup enables the characterization with TDS at low temperatures (T > 22 K) of portable sample designs, as is the case for scanning probe optimized setups or ...
متن کاملCochlear implant radiography: technique adapted into a portable apparatus.
UNLABELLED The unavailability of advanced imaging equipment in the operating rooms of most hospitals - as well as the fundamental importance for surgeons of immediate observation of the cochlear implants soon after their insertion - makes conventional radiography a good option. OBJECTIVE To describe a practical, fast and low-cost radiographic method, allowing for evaluation of the electrodes ...
متن کاملA Portable Apparatus for the Determina- Tion of Oxygen Dissolved in a Small Volume of Water
It is clear from the equations that each atom of oxygen in solution finally liberates one molecule of iodine. The iodine is titrated against sodium thiosulphate solution using starch as indicator; 1 c.c. of normal sodium thiosulphate solution corresponds to 8 mg. of oxygen, or 5-6 c.c. of oxygen at N.T.P. A number of modifications of the original technique of Winkler has been described. The acc...
متن کاملA simple, inexpensive, portable apparatus for injecting experimental chemicals in drip irrigation systems.
The loss of 1,2-dibromo-3-chloropropane (DBCP) as a postplant nematicide created a serious void in nematode protection for crops nationwide. An acceptable replacement for DBCP is needed, especially on susceptible perennials such as grapes, Vitis vinifera L. Phases of our postplant nematicide research were conducted in commercial vineyards where nematode disease existed on established vines wate...
