1. MGF Methods for Fixed and Gain Saturated Optically Preamplified FSO Links Impaired by Misalignments and Atmospheric Turbulence
Abstract The Gaussian approximation is commonly used to evaluate the performance of free space optical communication systems. However, other performance evaluation methods such as the saddle point approximation, Chernoff bound and the modified Chernoff bound have also been used. This paper investigates the performance of fixed and gain saturated optically pr

2. Molecular mechanisms of organ damage in sepsis: an overview
ABSTRACT Sepsis is one of the most common reasons for hospitalization. This condition is characterized by systemic inflammatory response to infection. International definition of sepsis mainly points out a multi-organ dysfunction caused by a deregulated host response to infection. An uncontrolled inflammatory response, often referred to as "cytokine storm",

3. DESIGN OF ELECTRONIC CONTROL GOVERNOR FOR A SINGLE CYLINDER GASOLINE ENGINE BASED ON AN INTELLIGENT SENSING ALGORITHM
ABSTRACT At present, most large machinery and vehicle engines are electronically controlled but their electronic control systems are too expensive to be popularised and applied in small gasoline engines with relatively low prices. Therefore, small gasoline engines still use mechanical speed regulators. Mechanical speed regulators not only have the defects of

4. Corticotropin-releasing factor receptor signaling and modulation: implications for stress response and resilience
Abstract Introduction In addition to their role in regulation of the hypothalamic-pituitary-adrenal-axis, corticotropin-releasing factor (CRF) and its related peptides, the urocortins, are important mediators of physiological and pathophysiological processes of the central nervous, cardiovascular, gastrointestinal, immune, endocrine, reproductive, and skin

5. FISHERMEN ECOLOGICAL KNOWLEDGE AND COMPLEX ADAPTIVE SYSTEMS: AN INTERPRETATIVE MODEL FOR SMALL-SCALE FISHERIES
RESUMO O conhecimento naturalístico (CN) resume a compreensão que os pescadores têm tanto da biologia das espécies, quanto das mudanças climáticas e oceanográficas relacionadas com a identificação de cardumes e sua captura. Ele é composto de uma linguagem complexa de códigos e sinais atualizada constantemente e transmitida oralmente através das g

6. Immune response of teleost fish to helminth parasite infection
Resumo O sistema imune dos peixes tem se tornado alvo de muitas pesquisas devido ao crescente desenvolvimento da aquicultura e da pesca, assim como a exigência de obtenção de animais saudáveis para o consumo humano. Dentre os parasitos responsáveis pelas enfermidades na piscicultura, os helmintos destacam-se por causarem infecções nos peixes cultivado

7. First record of Thaumastocoris peregrinus (Hemiptera, Thaumastocoridae) in Pará state, Brazil
RESUMO Thaumastocoris peregrinus (Hemiptera, Thaumastocoridae) é uma praga fitófaga de plantios de eucalipto introduzida no Brasil em 2008. A espécie expandiu-se rapidamente devido à sua capacidade adaptativa a diferentes condições climáticas. O eucalipto vem se expandindo na Amazônia brasileira desde a década de 1980, sendo usado em sistemas silvip

8. The role of GNLY gene polymorphisms in psoriasis pathogenesis
Abstract BACKGROUND: Psoriasis is a systemic inflammatory disorder that involves complex pathogenic interactions between the innate and adaptive immune systems. The most accepted mechanism in the etiopathogenesis of psoriasis is the induction of inflammation with keratinocyte hyperproliferation. Granulysin (GNLY) is a cytolytic antimicrobial peptide (AMP) t

9. The influence of contingencies factors strategy and structure in the enterprise risk management in a hospital
Resumo Apoiado na premissa de que o Enterprise Risk Management (ERM) é um Sistema de Controle Gerencial (SCG) e que, de acordo com a teoria de contingência, o design e o uso do SCG tende a variar de acordo com o contexto das organizações. O objetivo deste artigo é descrever como os fatores contingenciais estratégia e estrutura se inter-relacionam com

10. Extremum Seeking-based Adaptive PID Control applied to Neuromuscular Electrical Stimulation
Abstract A multivariable deterministic extremum seeking (ES) is being evaluated to construct an adaptive Proportional-Integral-Derivative (PID) control law for the functional Neuromuscular Electrical Stimulation (NMES) of stroke patients. The developed scheme is applied to control the position of the patient’s arm so that movements of flexion/extension for

11. Opioids in the immune system: from experimental studies to clinical practice
RESUMO INTRODUÇÃO: Os opioides interagem com ambos os sistemas imunes, inato e adaptativo, através de efeitos diretos sobre os receptores dos opioides localizados nas células imunes. As pesquisas neste assunto têm fornecido evidência da influência dos opioides sobre a resposta imune associada ao estresse cirúrgico. Os efeitos imunológicos dos opioi

12. Development of an indirect ELISA assay to evaluation of the adaptive immune response of pacu (Piaractus mesopotamicus)
ABSTRACT The pacu is one of the most important species for Brazilian fish farming and is considered emerging in the global aquaculture. Despite its importance, no effective tool for evaluation of the adaptive immune response of this species has been developed. Therefore, this study aimed the development and standardization of indirect ELISA for the measureme
