Efficiency data for MVG trays with truncated downcomers are presented for the first time. Various operating conditions including vacuum and high pressure are considered. While 7 bar and 11 bar data are very promising it has been possible to show that a uniform liquid flow pattern does indeed affect the efficiency at atmospheric pressure positively. A special downcomer outlet device has been dev...

This article describes a new method of preparing trays for indirect bracket bonding. Computer-aided technology is used to design the individualized trays, which are then produced with a rapid prototyping procedure. Application in clinical practice and the advantages of time savings and accurate bracket placement are discussed.

Individual sealing and tray wrap of orange (Citrus sinensis (L.) Osbeck cv. ‘Valencia’) with heat-shrinkable films of low-density polyethylene (LDPE), high-density polyethylene (HDPE), oriented polypropylene (OPP) and polyvinyl chloride (PVC) were held for a period up to 4 months at 5°C and 85-90% RH. Both methods of film-packaging showed little change in the water relations characteristics, wh...

The objective was to establish and evaluate a method for manufacture of custom trays for edentulous jaws using computer aided design and fused deposition modeling (FDM) technologies. A digital method for design the custom trays for edentulous jaws was established. The tissue surface data of ten standard mandibular edentulous plaster models, which was used to design the digital custom tray in a ...

RATIONALE Precise bony reduction and reconstruction of optimal contour in treating comminuted mandibular fractures is very difficult using traditional techniques and devices. The aim of this report is to introduce our experiences in using virtual surgery and three-dimensional (3D) printing technique in treating this clinical challenge. PATIENT CONCERNS A 26-year-old man presented with severe ...

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...
