PURPOSE The assessment of cortisol in hair has gained popularity as a means to measure retrospective hypothalamic-pituitary-adrenal activity in a number of species; however, cortisol levels from human hair subjected to typical chemicals for cosmetic or hygienic purposes may be altered by the chemicals used. The purposed of this study was to determine if exposure of hair to chemical processing o...

To understand the current Japanese hair mercury levels, we planned a survey of hair mercury among the general populations of different regions in Japan. The present paper, as the first report of the survey, summarized the results obtained in five districts, Minamata, Kumamoto, Tottori, Wakayama and Chiba. Hair samples were collected at beauty salons, barbershops and primary schools in each dist...

ABSTRACT The integrity of hair is determined by the intricate building blocks many layers follicle, but it also relies on proper nutrition. Weak can result from external factors such as physical trauma, heat manipulation, and chemicals, well internal inadequate A “hair diet” addresses both that lead to fragile or damaged provides basis for a conversation with patients improve health th...

I . The purpose of this paper is to propose the measurement of scalp hair diameter as a useful index of protein synthesis in the management of cases of malnutrition. 2. Observations on scalp hair from ten control infants showed that each hair tapered very gradually towards its free end. 3. Observations on scalp hair from twenty-six infants with kwashiorkor showed that each hair narrowed towards...

We present a two-way coupling technique for simulating the complex interaction between hair and fluids. In our approach, the motion of hair and fluids is simulated by evaluating the hydrodynamic forces among them based on boundary handling techniques used in SPH (Smoothed Particle Hydrodynamics) fluids. When hair makes contact with fluids, water absorption inside the hair volume can be simulate...

This paper presents an efficient method for generating and rendering photorealistic hair in two dimensional pictures. The method consists of three major steps. Simulating an artist drawing is used to design the rough hair shape. A convolution based filter is then used to generate photorealistic hair patches. A refine procedure is finally used to blend the boundaries of the patches with surround...

Inner and outer hair cells were mechanically isolated from the guinea pig cochlea and subjected to stimuli known to induce shape changes in outer hair cells. Depolarization by 70 mM KCl which causes osmotic swelling of outer hair cells also swelled inner hair cells by approximately 8% of their volume. The application of the calcium ionophore ionomycin which induces cortical contractions and elo...

Interactive styling of virtual hair is an important research field since it is essential for creating realistic looking human avatars for use in virtual worlds, computer games and movie special effects. Virtual hair models can contain thousands of hair strands and hence it is important to develop techniques which enable a designer to efficiently modify the hair in a realistic fashion. In this p...

In this paper we present a hybrid approach to reconstruct hair dynamics from multi-view video sequences, captured under uncontrolled lighting conditions. The key of this method is a refinement approach that combines image-based reconstruction techniques with physically based hair simulation. Given an initially reconstructed sequence of hair fiber models, we develop a hair dynamics refinement sy...

Hair occlusion often causes automated melanoma diagnostic systems to fail. We present a new method to segment hair in dermoscopic images. First, all possible dark and light hairs are amplified without prejudice with a universal matched filtering kernel. We then process the filter response with a novel tracing algorithm to get a raw hair mask. This raw mask is skeletonized to contain only the ce...
