1. A physiologically-based model for simulation of color vision deficiency
Color vision deficiency (CVD) affects approximately 200 million people worldwide, compromising the ability of these individuals to effectively perform color and visualization-related tasks. This has a significant impact on their private and professional lives. We present a physiologically-based model for simulating color perception. Our model is based on the

2. Photorealistic models for pupil light reflex and iridal pattern deformation / Modelos fotorealistas para dinâmica pupilar em função da iluminação e deformação dos padrões da iris
Este trabalho introduz um modelo fisiológico para o reflexo pupilar em função das condições de iluminação (Pupil Light Reflex - PLR), e um modelo baseado em imagem para deformação dos padrões da íris. O modelo para PLR expressa o diâmetro da pupila ao longo do tempo e em função da iluminação ambiental, sendo descrito por uma equação diferen

3. AvaliaÃÃes dosimÃtricas em pacientes submetidos à radioiodoterapia com base em fantomas de Voxels e em imagens de medicina nuclear
In radioiodine therapy, the patients are submitted to the incorporation of a radioactive Sodium Iodide substance (NaI), which reacts physiologically with metastases, thyroid tissue remainders and other organs and tissues of the human body. There is a complex question, which is, the evaluation of the temporal and spatial distribution of the absorbed dose in r

4. Morphology of the reproductive system of male thorny lobster Panulirus argus (Latreille, 1804) (Crustacea: Decapoda: Palinuridae) of coastline of the State of Cearà / Morfologia do sistema reprodutor masculino da lagosta espinhosa Panulirus argus (Latreille, 1804) (Crustacea: Decapoda: Palinuridae) do Litoral do Estado do CearÃ
The fishery of the spiny lobster Panulirus argus, found in the coast of the state of CearÃ, has been declining in the last years. Studies about the reproductive aspects of lobsters are still scarce, mainly for the males, needing investigations in the area of reproductive biology. The present study describes the morphology of the male reproductive system of

5. Computer modelling and simulation of human posture in standing with neuromuscular reflexes / Modelagem e simulaÃÃo do controle da postura ereta humana quasi-estÃtica com reflexos neuromusculares
This work presents a computer mathematical model of the human neuromusculoskeletal system specially designed to study the postural balance in standing. In addition to the extrafusal muscle tissue properties commonly used in traditional muscle models applied to study human movement and posture, this model includes two components physiologically important of p

8. Potential of physiologically based pharmacokinetics to amalgamate kinetic data of trichloroethylene and tetrachloroethylene obtained in rats and man.
A physiologically based pharmacokinetic model was used to amalgamate information obtained in rats and man by various routes of exposure to trichloroethylene (TRI) and tetrachloroethylene (TETRA). Since there have been no pharmacokinetic data on drinking water exposure, drinking water exposure to TRI was conducted in rats using 14C-TRI. Several partition coef

9. Physiologically Based Pharmacokinetic Model for Terbinafine in Rats and Humans
The aim of this study was to develop a physiologically based pharmacokinetic (PB-PK) model capable of describing and predicting terbinafine concentrations in plasma and tissues in rats and humans. A PB-PK model consisting of 12 tissue and 2 blood compartments was developed using concentration-time data for tissues from rats (n = 33) after intravenous bolus a

10. Physiologically based pharmacokinetic model for acetone.
OBJECTIVE--This study aimed to develop a physiologically based pharmacokinetic model for acetone and to predict the kinetic behaviour of acetone in the human body with that model. METHODS--The model consists of eight tissue groups in which acetone can be distributed: the mucous layer of the inhaled air tract, the mucous layer of the exhaled air tract, a comp

11. Uniqueness and Stability of Action Potential Models during Rest, Pacing, and Conduction Using Problem-Solving Environment
Development and application of physiologically detailed dynamic models of the action potential (AP) and Ca2+ cycling in cardiac cells is a rapidly growing aspect of computational cardiac electrophysiology. Given the large scale of the nonlinear system involved, questions were recently raised regarding reproducibility, numerical stability, and uniqueness of m

12. Effect of variation of exposure to airborne chlorobenzene on internal exposure and concentrations of urinary metabolite.
OBJECTIVES--This study aimed to develop a physiologically based pharmacokinetic model for chlorobenzene and to investigate the effect of variation in exposure to chlorobenzene on the chlorobenzene concentration in blood and the urinary concentration of 4-chlorocatechol. METHODS--A physiologically based pharmacokinetic model was developed and the simulated re
