In this simulation study the operation of conventional distillation column (column with one feed and two products) was investigated with the application of AspenPlus Dynamics software. Control structures of the column which separate a two-component mixture were studied. The aim of our investigations was to discover dynamic and steady-state effects of heating and cooling on tray temperatures. Th...

Many work environments can benefit from integrated computing devices to provide information to users, record users’ actions, and prompt users about the next steps to take in a procedure. We focus on the cell biology laboratory, where previous work on the Labscape project has provided a framework to organize experiment plans and store data. Currently developed sensor systems allow amount and typ...

work done in the past. This is an experiment which, if it is to be successful , will have to combine all that is good in the old system with the advantages and good points of the new. It is an experiment in which I personally believe the Cinderella of Medicine will become the most attractive branch of medicine. One of the great dangers of State medicine is that it may become impersonal. There i...

In order to perform medical surgeries, hospitals keep large inventories of surgical instruments. These instruments need to be sterilized before each surgery. Typically the instruments are kept in trays. Multiple trays may be required for a single surgery, while a single tray may contain instruments that are required for multiple surgical procedures. The tray optimization problem (TOP) consists ...

We have developed a Bayesian version of our likelihood-based Markov chain Monte Carlo genealogy sampler LAMARC and compared the two versions for estimation of theta = 4N(e)mu, exponential growth rate, and recombination rate. We used simulated DNA data to assess accuracy of means and support or credibility intervals. In all cases the two methods had very similar results. Some parameter combinati...

A radiotheraphy skin dose profile can be obtained with radiochromic film. The central axis skin dose relative to Dmax for a 10 x 10 cm2 field size was found to be 22%, 17% and 15.5% for 6 MV, 10 MV and 18 MV photon beams. Peripheral dose increased with increasing field size. At 10 MV the skin dose 2 cm outside the geometric field edge was measured as 6%, 10% and 17% for 10 x 10 cm2, 20 x 20 cm2...

Rehabilitation of a highly resorbed mandibular ridge can be a difficult and challenging one. Making an impression with available stock trays, even after modification is difficult in case of extremely resorbed ridges. In such cases, an innovative technique of making impression with properly adapted wire and silicone putty can be used to make a proper impression to achieve maximum retention and s...

The management of hemimandibulectomy case is a challenge relative to rehabilitation following the surgical treatment as the soft-tissue defects compromise the denture stability, support and retention. A major factor to be considered in this regard is the support for the partial denture. If the supporting teeth or soft tissues are not used correctly and completely, subsequent mobility of abutmen...

The current drive experiment-upgrade (CDX-U) at the Princeton Plasma Physics Laboratory has begun experiments with a fully toroidal liquid lithium limiter. CDX-U is a compact (R 1⁄4 34 cm, a 1⁄4 22 cm, Btoroidal 1⁄4 2 kG, IP 1⁄4 100 kA, Teð0Þ 100 eV, neð0Þ 5 10 m ) short-pulse (<25 ms) spherical torus with extensive diagnostics. The limiter, which consists of a shallow circular stainless steel ...

The characterization of cryogenic in vacuum permanent magnet undulators with periods less than 20 mm and correspondingly narrow gaps requires new in-vacuum measurement systems. The positioning accuracy of the HZB in-vacuum Hallprobe bench has substantially been improved (a few μm) with appropriate feedback systems. A new in-vacuum cable tray has been developed. Another system for field integral...
