1. A Mathematical Model for Accessing Dengue Hemorrhagic Fever in Infants
ABSTRACT A mathematical model was developed to describe the dynamics of the primary infection of dengue virus in infants who were born to a mother immune to some serotype of the dengue virus. The model is given by a system of nonlinear ordinary differential equations with time-dependent variables for the number of dengue virus antibodies of the infant transf

3. Strain Analysis of Left Ventricular Function in the Association of Hypertrophic Cardiomyopathy and Systemic Arterial Hypertension
Resumo Fundamentos: A cardiomiopatia hipertrófica (CMH) é a doença cardíaca de origem genética mais frequente na população mundial, com prevalência de, pelo menos, 1/500. A associação com hipertensão arterial sistêmica (HAS) não é incomum, uma vez que esta acomete aproximadamente 25% da população mundial. A maioria dos estudos objetiva o dia

4. Development, validity, and reliability of the General Activities of Daily Living Scale: a multidimensional measure of activities of daily living for older people
Objective: To propose and evaluate the psychometric properties of a multidimensional measure of activities of daily living (ADLs) based on the Katz and Lawton indices for Alzheimer's disease (AD) and mild cognitive impairment (MCI). Methods: In this study, 85 patients with MCI and 93 with AD, stratified by age (≤ 74 years, > 74 years), completed the Min

5. General exact harmonic analysis of in-plane timoshenko beam structures
The exact solution for the problem of damped, steady state response, of in-plane Timoshenko frames subjected to harmonically time varying external forces is here described. The solution is obtained by using the classical dynamic stiffness matrix (DSM), which is non-linear and transcendental in respect to the excitation frequency, and by performing the harmon

6. Detecção de fraudes em transações financeiras via Internet em tempo real. / Frauds detections in financial transactions via Internet in real time.
Um dos objetivos mais importantes de qualquer sistema de detecção de fraudes, independente de seu domínio de operação, é detectar o maior número de fraudes com menor número de alarmes falsos, também denominados de falsos positivos. A existência de falsos positivos é um fato inerente a qualquer sistema de detecção fraudes. O primeiro passo para a

7. Estudo numérico da aplicação do método dos elementos finitos de Galerkin e dos mínimos quadrados na solução da equação da convecção-difusão-reação tridimensional / Numerical study of the application of Galerkin and least squares finite element methods in the solution of the tridimentional convection-diffusion-reaction equation
This paper the application of the Finite Element Method in variants Galerkin and Least Squares with auxiliary equations for the numerical solution of partial differential equation that models the convection-diffusion-reaction defined over a three-dimensional domain in steady state. In the spatial discretization were used hexahedrons elements with eight (line

8. cDNA-AFLP analysis of gene expression differences between the flower bud and sprout-shoot apical meristem of Angelica sinensis (Oliv.) Diels
Angelica sinensis (Oliv.) Diels (Umbelliferae) is a well-known medicinal plant mainly distributed in Gansu Province of China. Its local and global demand is significant because of its food and medicinal applications. However, the early bolting rate of Angelica sinensis (Oliv.) Diels reaches 20%-60%, which seriously affects its food and medicinal qualities. T

11. Identificação e caracterização de genes candidatos para a tolerância à seca em cafeeiro / Identification and characterization of candidate genes for drought tolerance in coffee
Coffee is economically important and widely cultivated in Brazil. The cultivated area is well distributed throughout the territory, whereby C. arabica and C. canephora are produced, depending on the region. Usually, drought and adverse temperatures are the major weather constraints to coffee production. The importance of such limitations should increase, acc

12. Exploration of genes related to the occurrence of diseases in shrimp Litopenaeus vannamei (Boone, 1931) under conditions of cultivation / Prospecção de genes relacionados à ocorrência de enfermidades no camarão Litopenaeus Vannamei (Boone, 1931) sob condições de cultivo
The marine shrimp culture has achieved great importance in the global economy as an agriculture business, not only for jobs and income generation, but especially because it represents a viable alternative source of animal protein for the growing global food demand. However, the occurrence of diseases in shrimp culture, especially those of viral aetiology, ha
