background and aims. change in the resting whole-mouth salivary flow rate (sfr) plays a significant role in pathogenesis of various oral conditions. factors such as smoking may affect sfr as well as the oral and dental health. the primary purpose of this study was to determine the effect of smoking on sfr, and oral and dental health. materials and methods. one-hundred smokers and 100 non-tobacc...

Solid freeform fabrication (SFF) allows 3D-printing of arbitrarily shaped structures, directly from computer-aided design (CAD) data. SFF has traditionally focused on printing passive mechanical parts. Advances in this technology and developments in materials science make it feasible to begin the development of a single, compact, robotic SFF system – including a small set of materials which can...

This study investigated the potential of a newly proposed scattering foil free (SFF) electron beam scanning technique for the treatment of skin cancer on the irregular patient surfaces using Monte Carlo (MC) simulation. After benchmarking of the MC simulations, we removed the scattering foil to generate SFF electron beams. Cylindrical and spherical phantoms with 1 cm boluses were generated and ...

REASONS FOR PERFORMING STUDY Previous studies of sinus surgery on standing horses have been based on techniques which utilise powered hand bone saws and preserve the bone flap, which was thought to be essential for a good cosmetic result. This report describes a simplified technique applied to the standing horse where the sinus flap construction used a large skull trephine and where the bone fl...

We investigate the [O II] emission-line as a star formation rate (SFR) indicator using integrated spectra of 97 galaxies from the Nearby Field Galaxies Survey (NFGS). The sample includes all Hubble types and contains SFRs ranging from 0.01 to 100 M⊙ yr . We compare the Kennicutt [O II] and Hα SFR calibrations and show that there are two significant effects which produce disagreement between SFR...

background: chewing sugar-free gums is a convenient way to increase salivary flow. salivary flow increases in response to both gustatory (taste) and mechanical (chewing) stimuli, and chewing gum can provide both of these stimuli. the aim of this study was to compare the effect of five different flavors of sugar-free chewing gum on the salivary flow rate (sfr) and ph. materials and methods: fift...

Dear Editor We appreciate the comments by Gundogan et al. [1] on our paper entitled ‘Multifocal electroretinograms in Stargardt’s disease/fundus flavimaculatus’, published in Ophthalmologica [2] . They asked us to present more details on the full-field electroretinograms (ERGs) and also to calculate the correlation between the visual amplitudes of the multifocal ERGs’ central response, the visu...

In this letter we propose a new Shape from Focus (SFF) method using piecewise curved search windows for accurate 3-D shape recovery. The new method uses piecewise curved windows to compute focus measure and to search for Focus Image Surface (FIS) in image space. The experimental result shows that our new method gives more accurate result than the previous SFF methods. key words: CCD camera, foc...

The anisotropies of cosmic far-infrared background (CFIRB) probe the star formation rate (SFR) of dusty star-forming galaxies as a function of dark matter halo mass and redshift. We explore how future CFIRB experiments can optimally improve the SFR constraints beyond the current measurements of Planck. We introduce a modelindependent, piecewise parametrization for SFR as a function of halo mass...

TRADEWIND is a prototype electronic marketplace for SFF processes. This marketplace facilitates the interaction between designers and manufacturers from the initial request for bids to build a design up to transaction closure. The system is built with three distinct layers of functionality corresponding to the market functions of presence and accreditation, bid resolution and transaction closur...
