The increasing demands of education, reduction of study cost and study without location limitation have encouraged developers providing different types of learning and educational systems. This paper presents a virtual Chinese hairy brush painting environment which can be used as a digital tool for learning or creating Chinese calligraphy or Chinese painting. The framework comprises two compone...

AIM Toothbrushing effectiveness can be improved with at-home reinforcement of proper technique. This study evaluated the ability of a power brush with a wireless remote display (Oral-B Triumph with SmartGuide) to improve brushing force and thoroughness. METHODS AND MATERIALS At baseline, 61 pre-screened subjects were videotaped while brushing. The wireless display was also videotaped. Subject...

introduction & objective: foreign body ingestion is a common and important condition that can be life threatening if not diagnosed and treated properly. diagnosis is especially difficult in patients with unusual symptoms. this study was performed to determine the incidence and complications of foreign body ingestion in the patients referred to shiraz khalili hospital. materials & methods: in th...

Nacrtak Forest biomass from timber harvesting residues is often used during mechanized forest opera­ tions to improve trafficability of strip roads (machine operating trails). In particular, during cut-to-length operations brush mats from harvesting residues are created on operating trails to reduce rutting. However, forest biomass is becoming increasingly important as a source of renewable ene...

BACKGROUND Cancer of the oral cavity is the sixth most common malignancy reported worldwide and one with the highest mortality rate among all malignancies. There is a paucity of reliable diagnostic methods to detect early malignancies. This study was performed to evaluate the sensitivity and specificity of brush biopsy in identifying oral premalignant and malignant lesions. METHODS Oral brush...

Background: World wide, Cervical cancer comprises 12% of all cancers in women. In developed countries, routine cervical cytology tests resulted in a large decline in cervical cancer incidence. This study is a descriptive- analytical research to evaluate the order of cell sampling from exocervix and endocervix and compare final cytological diagnosis. Materials and methods: Totally, 1129 smears ...

Two extremely high molecular weight proteins were found to be components of the intestinal epithelial cell brush border cytoskeleton. The largest brush border protein, designated T-protein, migrated on SDS gels as a doublet of polypeptides with molecular weights similar to muscle titin T I and T II. The other large brush border protein, designated N-protein, was found to have a polypeptide mole...

A theory describing layers of polymer chains grafted to a flat surface (polymer 'brush') is developed. We consider a brush of chains with arbitrary extensibility and, within the framework of molecular field theory, we suggest a general scheme for calculating the selfconsistent pseudo-potential, which determines the structure of the brush. This potential appears to be defined only by the mechani...

This thesis presents a method for creating simulated oil paintings. A raster image is next used as input to an algorithm that produces a painting-like image composed of brush strokes rather than pixels. Ultimately the sequence of brush strokes representing an interpreted image can be rendered in pixel form, however the brush stroke structure is far more compact for storage and transmission. Unl...
