1. The impact of COVID-19 in medical practice. A review focused on Urology
ABSTRACT COVID-19 pandemic is a rapidly spreading virus that is changing the World and the way doctors are practicing medicine. The huge number of patients searching for medical care and needing intensive care beds led the health care system to a burnout status especially in places where the care system was already overloaded. In this setting, and also due t

2. O conceito de violência de professoras do ensino fundamental.
The main objective of this study is to describe the concept of violence of a social group made up of fundamental school teachers belonging to public and private schools. In order to address different description levels, the following categories were established: class, modality and form of violence. In order to contextualize the conceptualized violence, its

3. Propagação de danos no modelo de Potts / Damage spreading in the Potts model
Estudamos as transições de fase no modelo de Potts com q estados (q = 2, ..., 7) por meio de simulações de Monte Carlo e propagação de danos. Este modelo apresenta um comportamento crítico rico, com transições de fase de segunda (q [

4. Damage spreading in a model of gene regulation in scale-free networks / Damage spreading in a model of gene regulation in scale-free networks / Propagação de danos em um modelo de regulação gênica em redes livres de escalas / Propagação de danos em um modelo de regulação gênica em redes livres de escalas
A compreensão de todos os elementos funcionais que controlam a expressão gênica é um desafio da biologia molecular moderna. Vários avanços no entendimento do funcionamento das redes de genes foram feitos com a descrição desse sistema complexo por meio de modelos de redes. A caracterização dessas redes permite conhecer como tais sistemas são organi

5. Stochastic dynamics of coupled systems and damage spreading
We study the damage spreading in the one-dimensional Ising model by means of the stochastic dynamics resulting from coupling the system and its replica by a family of algorithms that interpolate between the heat bath and the Hinrichsen-Domany algorithms. At high temperatures the dynamics is exactly mapped to the Domany-Kinzel probabilistic cellular automaton

6. Monte Carlo dinâmico aplicado aos modelos de Ising e Baxter-Wu. / Dynamic Monte Carlo method applied to Ising and Baxter-Wu models.
Investigações da dinâmica crítica em modelos de magnetismo, para tempos curtos, têm aparecido com grande freqüência na literatura. Essa técnica foi descoberta por Li, Schülke e Zheng que, inspirados em trabalhos anteriores de Huse e Janssen et al., mostraram que generalizações de grandezas como a magnetização e o cumulante de Binder exibem compo

7. Damage spreading in the one-dimensional Hinrichsen-Domany model
In this paper we study damage spreading in a one-dimensional model under two dynamics introduced by Hinrichsen and Domany. In particular, we study the effects of synchronous and asynchronous updating on the spreading properties. We show that the damage does not spread when the second dynamic is implemented in a synchronous way. We find that the rules for upd

8. NutriÃÃo, hipertiroidismo precoce e desenvolvimento cerebral: estudo em ratos recÃm-desmamados
It is known that early alterations of thyroid function interferes with cerebral development and physiology. In this work we investigated the effects of early treatment with thyroxin (T4) on the propagation of cortical spreading depression (SD) in weaned rats. Female adult Wistar rats fed a lab chow diet (CD; 23% protein) were treated with T4 (20ug/kg/day, si

9. Propagação de danos no modelo de ising em redes de bravais e em fractais
In this work we have studied, by Monte Carlo computer simulation, several properties that characterize the damage spreading in the Ising model, defined in Bravais lattices (the square and the triangular lattices) and in the Sierpinski Gasket. First, we investigated the antiferromagnetic model in the triangular lattice with uniform magnetic field, by Glauber

10. CD28 Costimulatory Blockade Exacerbates Disease Severity and Accelerates Epitope Spreading in a Virus-Induced Autoimmune Disease
Theiler's murine encephalomyelitis virus (TMEV) is a natural mouse pathogen which causes a lifelong persistent infection of the central nervous system (CNS) accompanied by T-cell-mediated myelin destruction leading to chronic, progressive hind limb paralysis. TMEV-induced demyelinating disease (TMEV-IDD) is considered to be a highly relevant animal model for

11. Endogenous presentation of self myelin epitopes by CNS-resident APCs in Theiler’s virus–infected mice
The mechanisms underlying the initiation of virus-induced autoimmune disease are not well understood. Theiler’s murine encephalomyelitis virus–induced demyelinating disease (TMEV-IDD), a mouse model of multiple sclerosis, is initiated by TMEV-specific CD4+ T cells targeting virally infected central nervous system–resident (CNS-resident) antigen-present

12. Freezing of Barley Studied by Infrared Video Thermography1
Freezing of barley (Hordeum vulgare), Hordeum murinum, and Holcus lanatus was studied using infrared video thermography. In the field, ice could enter H. lanatus leaves through hydathodes. In laboratory tests with barley, initially 0.4% of the leaf water froze, spreading in alternate strips of high and low freezing intensity longitudinally at 1 to 4 cm
