background and objective: cervical cancer involves many women annually and pop smear test has played a significant role in reducing its mortality and for this reason, its improvement is very essential. in this respect, cervex brush is a new tool that has been introduced in many countries. therefore, this study was conducted to compare pop smears from cotton swab-spatula and cervex brush methods...

In this paper, we present a smart sketch-based algorithm for simulating Oriental brush strokes on shapes. The user inputs the contours of the shape to paint. The system first estimates automatically the optimal trajectory of the brush, and then renders the shape into Oriental ink painting style by direct brush texture mapping. We formulate the problem of optimal brush trajectory estimation as t...

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...

Foam thin liquid films (TLF) and monolayers at the air-water interface formed by DMPC mixed with DMPE-bonded poly (ethylene glycol)s (DMPE-PEG(550), DMPE-PEG(2000) and DMPE-PEG(5000)) were obtained. The influence of both (i) PEG chain size (evaluated in terms of Mw) and mushroom-to-brush conformational transition and (ii) of the liposome/micelle ratio in the film-forming dispersions, on the int...

Using a combination of ellipsometry and friction force microscopy, we study the reversible swelling, collapse and variation in friction properties of covalently bound poly(N-isopropylacrylamide) (PNIPAM) layers on silicon with different grafting densities in response to exposure to good solvents and co-nonsolvent mixtures. Changes in the thickness and segment density distribution of grafted fil...

Although the aleurone layer of ceral grain seeds has many advantages for the study of gibberellin action, it has the disadvantage that the hand-isolation of the aleurone layers is time-consuming. To overcome this disadvantage, a commercially available pasta machine was modified and used to remove aleurone layers from imbibed barley (Hordeum vulgare) seeds. This equipment allows isolation of a t...

The electrochemical properties of cytochrome c (cyt c) immobilized on multilayer nanozeolite-modified electrodes have been examined in aqueous and nonaqueous solutions. Layers of Linde type-L zeolites were assembled on indium tin oxide (ITO) glass electrodes followed by the adsorption of cyt c, primarily via electrostatic interactions, onto modified ITO electrodes. The heme protein displayed a ...

A new class of surface-structured RO membranes was developed with a hydrophilic brush layer of terminally anchored polymer chains resulting in fouling resistant membranes of low mineral scaling propensity and high permeability. The approach is based on free-radical graft polymerization of a suitable monomer, onto the active polyamide (PA) layer of a thin film composite (PA-TFC) membrane, post-s...

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...
