Our purpose is to show the effects in the predator-prey trajectories due to parameter temporal perturbations and/or inclusion of capacitive terms in the Lotka Volterra Model. An introduction to the Lotka Volterra Model (chapter 2) required a brief review of nonlinear differential equations and stability analysis (chapter 1) , for a better understanding of our work. In the following chapters we display in sequence our results and discussion for the randomic pertubation case (chapter 3); periodic perturbation (chapter 4) and inclusion of capacitive terms (chapter 5). Finally (chapter 6) we synthesize our result

A disseminação de um estilo de vida saudável aliado a um relativo aumento de renda da população brasileira vem provocando um aquecimento no setor de negócios relacionados a atividade física. Nesse contexto, com esse frequente aumento no numero de academias, o cliente tem ampla rede de opção em relação a qual local escolher para desfrutar dos serviços oferecidos. A academia, para acolher o maior numero de clientes, deve oferecer diferenciais em seus serviços. É nessa hora que o profissional de educação física faz grande diferença, através de uma qualificação e capacidade profissional apurada, oferece um serviço de qualidade elevada, posicionado assim a academia em destaque no mercado. Nesse contexto, parece notório que a qualificação profissional, como foco no direcionamento técnico e na especificidade dos serviços oferecidos, não alcança a dinâmica administrativa e de gestão de pessoal. É dentro dessa abordagem que esse trabalho tentará alcançar uma visibilidade dentro do tema e uma abertura para a reflexão sobre a necessidade de aprimoramento teórico na área

Projeto arquitetônico que consiste na construção de um novo Hospital da Mulher em São José do Rio Preto – SP, que foi o primeiro hospital exclusivo para o público feminino da cidade e da região. A ideia era trabalhar apenas com cirurgias limpas ou potencialmente não contaminadas (como cirurgias vasculares, obstétricas, ginecológicas e plásticas), ou seja, com menores riscos de infecção (muito importante principalmente no caso de partos prematuros e do cada vez mais alto percentual de bebês que morrem por causa de infecções hospitalares). Um dos diferenciais do hospital era oferecer ambientes que lembravam uma casa de repouso e instalações hoteleiras, descaracterizando-o de um hospital comum. O investimento em instalações fazia parte do incentivo ao “turismo de saúde” da cidade, que atraia diariamente pacientes de vários municípios e Estados do País. Atualmente o local do antigo hospital é ocupado por uma clínica privada, sendo necessária a construção de um novo prédio, que viria de encontro aos anseios da cidade que, por possuir a Faculdade de Medicina de Rio Preto (FAMERP), vinculada à UNICAMP, ser um pólo regional de saúde com referências à nível nacional teria potencial para abranger uma grande demanda de pacientes diferenciados

Synchronization in nonlinear dynamical systems, especially in chaotic systems, is field of research in several areas of knowledge, such as Mechanical Engineering and Electrical Engineering, Biology, Physics, among others. In simple terms, two systems are synchronized if after a certain time, they have similar behavior or occurring at the same time. The sound and image in a film is an example of this phenomenon in our daily lives. The studies of synchronization include studies of continuous dynamic systems, governed by differential equations or studies of discrete time dynamical systems, also called maps. Maps correspond, in general, discretizations of differential equations and are widely used to model physical systems, mainly due to its ease of computational. It is enough to make iterations from given initial conditions for knowing the trajectories of system. This completion of course work based on the study of the map called ”Zaslavksy Web Map”. The Zaslavksy Web Map is a result of the combination of the movements of a particle in a constant magnetic field and a wave electrostatic propagating perpendicular to the magnetic field. Apart from interest in the particularities of this map, there was objective the deepening of concepts of nonlinear dynamics, as equilibrium points, linear stability, stability non-linear, bifurcation and chaos

Cancer biology is a complex and expanding field of science study. Due its complexity, there is a strong motivation to integrate many fields of knowledge to study cancer biology, and biological stoichiometry can make this. Biological stoichiometry is the study of the balance of multiple chemical elements in biological systems. A key idea in biological stoichiometry is the growth rate hypothesis, which states that variation in the carbon:nitrogen:phosphorus stoichiometry of living things is associated with growth rate because of the elevated demands for phosphorusrich ribosomal RNA and other elements necessary to protein synthesis. As tumor cells has high rate proliferation, the growth rate hypothesis can be used in cancer study. In this work the dynamic of two tumors (primary and secondary) and the chemical elements carbon and nitrogen are simulate and analyzed through mathematical models that utilize as central idea biological stoichiometry. Differential equations from mathematical model are solved by numerical method Runge-Kutta fourth order

Even today tables are used in the calculation of structures formed by flat elements, these methods are acceptable only for a limited number of cases, but even so, in some situations, tables are used. With time some methods of differential equations resolutions were emerging and accepted as the most effective solution. Today, with the advancement in technology, there are already some programs able to solve more complex problems in less time using these methods. Aiming to optimize time and better understand the physical behavior of plates, this work presents the theory of plate, the Boundary Element Method (BEM) applied to solve problems of plates (slabs) with various boundary conditions and load through the program Placas2 (TAGUTI, Y.-2010) in Fortran language

Seizure is a clinical manifestation of abnormal neuronal hyperactivity of the cerebral cortex, presentation clinical varies according to the location and extent of the brain. The classic seizure begins with an inicial period, named prodrome, followed by the aura, the ictus and finally the post-ictus phase. Seizures can be generalized or focal/partial types. Focal seizures with secondary generalization are the most common type in dogs. The seizure can be divided etiologically in intracraneal (idiopathic epilepsy; sintomatic; probably sintomatic epilepsy) and extracraneal disorders. After determining the etiology of seizures and critical analysis of the frequency, severity, and worry they cause to the owner, you should make the decision whether to launch an anticonvulsant drug therapy. Although the ideal is the elimination of seizures, the real goal should be to decrease the frequency and intensity of crises, without affecting the quality of life of patients taking the drugs used side effects acceptable. The veterinary should consider the bioavailability of the drug, contraindications, toxicity, drug interactions, the amount of daily administration, the availability of the owner and the cost of therapy. Seizures can be controlled in about 70- 80% of the dogs and in the majority of the cats when treated with Phenobarbital alone. Addition of a second drug (usually potassium bromide), decreases the number of seizures in more that 50% in about 70-80% of dogs. However, approximately 20-30% of dogs are refractory to this treatment. In these cases, it will be necessary to think in other pharmacological alternatives, like felbamate, gabapentin, levetiracetam, zonisamid, among others. It has been concluded that...
