    The land expropriation process is a huge problem for transport infrastructure projects, since this process is always slow and socially sensitive. Therefore, adoption of strategies to mitigate the expropriation problems is essential to avoid future problems. The use of simulation program is an important tool for planning, allowing analyze different scenarios and improve path option from different variables in a decision matrix. Thus, previous studies of expropriation provide elements that enable to define measures to mitigate the social impacts and risks during the works. The objective of this research is to develop a methodology for preliminary analysis of expropriation in federal railways studies. In the current study is considered one of the simulated trajectories for the high-speed train between Rio de Janeiro and São Paulo. The result shows that the hypothetical railway produces low social impact in comparison with other federal transportation routes.O processo de desapropriação de terras é um grande problema para projetos de infraestrutura de transporte, uma vez que este processo é sempre lento e socialmente sensível. Portanto, a adoção de estratégias para mitigar os problemas de desapropriação é essencial para evitar problemas futuros. O emprego de simulações é uma ferramenta importante para o planejamento, permitindo analisar diferentes cenários e definir a melhor opção do trajeto a partir de diferentes variáveis em uma matriz de decisão. Portanto, os estudos anteriores de desapropriação fornecem elementos que permitem definir medidas para mitigar os impactos sociais e riscos durante as obras. O objetivo dessa pesquisa é desenvolver uma metodologia para a análise preliminar de desapropriação em estudos de vias federais. No presente estudo é analisada uma das trajetórias simuladas para uma ferrovia para trens de alta velocidade entre o Rio de Janeiro e São Paulo. O resultado demonstra que a hipotética via férrea produz baixos impactos sociais, em comparação com outras vias federais

    Mitochondrial physiology

    As the knowledge base and importance of mitochondrial physiology to evolution, health and disease expands, the necessity for harmonizing the terminology concerning mitochondrial respiratory states and rates has become increasingly apparent. The chemiosmotic theory establishes the mechanism of energy transformation and coupling in oxidative phosphorylation. The unifying concept of the protonmotive force provides the framework for developing a consistent theoretical foundation of mitochondrial physiology and bioenergetics. We follow the latest SI guidelines and those of the International Union of Pure and Applied Chemistry (IUPAC) on terminology in physical chemistry, extended by considerations of open systems and thermodynamics of irreversible processes. The concept-driven constructive terminology incorporates the meaning of each quantity and aligns concepts and symbols with the nomenclature of classical bioenergetics. We endeavour to provide a balanced view of mitochondrial respiratory control and a critical discussion on reporting data of mitochondrial respiration in terms of metabolic flows and fluxes. Uniform standards for evaluation of respiratory states and rates will ultimately contribute to reproducibility between laboratories and thus support the development of data repositories of mitochondrial respiratory function in species, tissues, and cells. Clarity of concept and consistency of nomenclature facilitate effective transdisciplinary communication, education, and ultimately further discovery

    p. 125-130There are 28 unequivocal reports of heterotopic mesenteric ossification (HMO) in the medical literature. Most cases are poorly defined lesions in intra-abdominal structures that cause intestinal obstruction. A small well-delineated solid mass was reported in only one patient with no previous history of trauma. We report herein the case of a 67 year-old female patient with calcified mass in the left adnexal region. The awareness of HMO may avoid an erroneous diagnosis of extraskeletal osteosarcoma. This case differs from most cases of HMO as it is the third one reported in females and does not present a diffuse involvement, which leads to obstructive symptoms

    Case report – hymenal rupture in abused child: rape or sexual abuse otherwise copulation?

    Os autores apresentam o caso de uma criança de cinco anos morta por esganadura, que apresentava também sinais de espancamento e de violência sexual. A dificuldade de caracterizar a violência sexual, se estupro ou atentado violento ao pudor, está na realização do diagnóstico de conjunção carnal. A literatura médica mostra que um dos elementos fundamentais para este diagnóstico é o hímen e suas características, porém, a rotura himenal, mesmo recente, pode ser questionada como sinal de certeza, já que esta pode ocorrer em traumatismos acidentais da região perineal.The authors presents the case of a five years old child that was murdered by hands strangled and also she had signs of physical and sexual abuse. The difficulty of characterizing the sexual violence, if was rape or sexual abuse otherwise copulation, was diagnosing sexual intercourse. The medical literature indicates that the hymenal characteristics are the essencial element for this diagnose. However, the hymenal rupture, recent or not, like certain sign would be controversial if accidental trauma occurred in the perineum
