background: different factors such as impression techniques and materials can affect the passive fi t between the superstructure and implant. the aim of this study was to determine the effect of different impression materials and techniques on the dimensional accuracy of implant defi nitive casts. materials and methods: four internal hex implants (biohorizons ø4 mm) were placed on a metal maxil...

We present a framework, called TrayGen, to generate tray designs for the exhibition and packaging of a collection of objects. Based on principles from shape perception and visual merchandising, we abstract a number of design guidelines on how to organize the objects on the tray for the exhibition of their individual features and mutual relationships. Our framework realizes these guidelines by a...

This study has created the Playful Tray that adopts Ubicomp and persuasive techniques into play-based occupational therapy for reducing poor eating behavior in young children after they reached their self-feeding age. The design of the Playful Tray reinforces active participation of children in the activity of eating by integrating digital play with eating. Results of a pilot user study suggest...

In this study, the Taguchi method is used to find the optimal process parameters for an injection moulding machine that was used to produce a consumer product (plastic tray) from polypropylene (PP) plastic material. An orthogonal array (OA), main effect, signal-to-noise (S/N) ratio, and analysis of variance (ANOVA) were employed to investigate the bending characteristics of the tray under a con...

In recent years there has been considerable interest in laboratory rearing of Toxorhynchites mosquitoes for use as biological control agents (Vongtangswad and Trpis 1980) and foi the assay of dengue viruses (Eshita et al. 1982). Although larvae of these mosquitoes are cannibalistic (Steffan and Evenhuis 1981), mass rearing methods have been described for some species which have yielded pupation...

Five methods for extracting nematodes from soil were compared using three sandy soils and three clay soils. Although no one method was superior to the others for all the genera in any one particular soil, the decanting plus sieving plus Baermann tray method was generally the most efficient for sandy soils and the decanting plus sieving plus centrifugal sugar flotation method the most efficient ...

a solid state fermentation method was used to utilize wheat straw as substrates for citric acid production by using aspergillus niger atcc 9142. the plackett burman design (pbd) of experiments was used to test the relative importance of the variables affecting production such as moisture content, age of spore, inoculum size, initial ph of substrate, methanol concentration, incubation temperatur...
