The objective of this essay is to examine the trajectory of a clandestine organization that, despite being rather active and frequently cited by the academic literature, has not been very visible in Brazilian history: the Military Sector of the PCB, or Antimil. The particularity of this project is to learn about Antimil’s organizational structure in the process of intervening in the Armed Forces between 1929 and 1945. It does not pretend to evaluate its revolutionary efficacy or all the situations in which it was involved, due to the lack of documentation and specific studies. The revelation of its historical configuration, as an organization in the party structure, is the result of exhaustive research and the narratives of some of its members.

This text aims to present a very short review on Machiavelli’s ideas reception concerning his military thought and short reflections on international affairs, as part of what was called realism in the realm of international relations theory. The text deals with much more emphasis the mentioned interpretations in a very concise way within contemporary studies about maquiavelian legacy on contemporary studies in International Relations.

O nitrato de fenticonazol é um derivado imidazólico de amplo espectro de ação contra patógenos dermatófitos, como Malassezia furfur e leveduras, a principal delas Candida albicans. É necessário que se possa garantir a qualidade dos medicamentos produzidos. O controle de qualidade é uma ferramenta que assegura a qualidade, eficácia e segurança desses produtos até o momento de sua utilização e faz-se necessário que métodos analíticos sejam desenvolvidos e validados para o doseamento desses fármacos. A grande importância dos métodos microbiológicos utilizados no controle de qualidade de fármacos com atividade antimicrobiana é demonstrar sua atividade biológica por meio de seu efeito inibitório no crescimento de micro-organismo. A diminuição da atividade antimicrobiana ou potência pode indicar alguma alteração sutil na molécula, que é pouco detectável em um método analítico físico-químico. O objetivo deste trabalho foi desenvolver e validar o método microbiológico difusão em ágar para o produto nitrato de fenticonazol creme vaginal. O método de difusão em ágar foi desenvolvido utilizando meio de cultura ágar Sabouraud e cepa de Candida albicans ATCC 64548 como micro-organismo teste. Para o ensaio foi utilizado o delineamento 3 x 3, conforme preconiza a Farmacopeia Brasileira (2010). A validação do método proposto demonstrou linearidade entre os diâmetros dos halos de inibição e o logaritmo da concentração na faixa de 50,0 a 200,0 μg/mL. O método obteve resultados precisos e lineares com r2=1. A exatidão foi comprovada pelo intervalo de tolerância de 98,83%, dentro dos limites permitidos. O método foi validado de maneira satisfatória, podendo ser utilizado em análises do Controle de Qualidade deste fármaco.

In this work we report the development of a tube amplifier built to be used in magnetic probe diagnostic of plasma. The probe is used to measure the magnetic field in the theta-pinch system presently running in our university. We present the calculations and procedures to determine the configuration of circuits and specify the components of the power supply, the preamp stage and the power stage. The circuit configuration and the characteristics of the components was obtained. A representative model of the system behavior gave the transfer function of the amplifier. Theoretical predictions of frequency response and the feedback effects were compared to the experimental values and showed very good agreement. The amplifier works between a frequency bandwidth of 20 an 30 kHz and supply a maximum power of 12 W

The expansion of the electrical system is currently a subject of great importance to the development of Brazil. For its realization, large projects are needed, requiring large-scale investment and realization processes of great complexity. Thus, this type of project has a high strategic importance for the performance of companies that conduct. Seeking a way to determine a method to align traditional practices for measuring quality to the corporate strategic needs, this work is the study of the use of the balanced scorecard methodology, applying quality management and operational excellence, with a focus on projects in power systems. We analyzed some cases of successful application of the methodology in business segments in the next study, culminating in a proposed model of the method

The objective of this study was to analyze the influence of previous exercise on the determination of critical power (CP). Seven apparently healthy nontrained males, of 18 to 25 years, participated of this study. The subjects were submitted, in different days to the following protocols in a cyclergometer: 1) one progressive test until voluntary exhaustion for the determination of lactate threshold (LL), maximal oxygen uptake (VO2max) and its corresponding intensity (IVO2max); 2) six constant workload tests at 95,100 and 110% IVO2max until exhaustion with and without a previous exercise at 70% , in random order. The exhaustion times (tlim) at 95, 100 and 110% IVO2max were adjusted forme thress models of two parameters to estimate CP and anaerobic work capacity (AWC) [P=CTAn/tlim)+CP; tlim = CTAn/(P-PC); P=PC.tlim+ CTAn]. The model with the lowest standard error was considered for the estimation of CP. The tlim at 95% IVO2max was similar without (501 ± 140 s) and with previous exercise (473 ± 99 s). However, the tlim at 100% (381 ± 103 s and 334 ± 101 s) and 110% IVO2max (267 ± 163 s and 227 ± 68 s) was significantly longer with previous exercise. There was no significant difference in CP and AWCat conditions without (200 ± 27 W and 23 ± 11 kJ, respectively) and with previous exercise (212 ± 30 W and 18 ± 8 kJ, respectively). It can be concluded that the parameters of the relationship between power and time were not modified by the previous severe exercise

This paper presents a comparative study based on literature and examples in the literature, the two main technologies for the transmission of electricity at high voltage: alternate current transmission and direct current transmission. Inside the direct current transmission will be shown two technologies currently employed, transmission by current source and transmission by voltage source, contributing to a better understanding of them. The ultimate goal is to provide a text for consultation to identify key characteristics that influence the choice of future transmission lines
