This paper presents a fuzzy tuning system for real-time industrial PID （proportional-integral-derivative） controllers. The algorithm set the proportional gain, integral time and derivative time of a classical PID structure according to the set point, error and error derivative of the process, respectively. The tuning of the PID controller is based on a fuzzy inference machine. The set of rules of the fuzzy inference machine was obtained by experts engineering. The system is tested in an austempering process but can be applied in any industrial plant. Besides, an analysis between the response of the process with a PID controller and the system of fuzzy auto-tuning for P1D proposed was made.

Currently, multiple lines of cytotoxic chemotherapy for treatment of metastatic breast cancer are available, and Taxanes, used as monotherapy or in combination with anti-angiogenic drugs, such as Bevacizumab, are one of the most used schemes in clinical practice. These drugs have different side effects and the liver is one of the most affected organs. The objective of this paper is to report three cases of metastatic breast cancer with positive expression of hormone receptors and without amplification of HER-2 protein that were treated with Taxane and Bevacizumab, developed pseudocirrosis probably caused by these drugs and died due to liver failure. It can be drawn from the study that liver failure, as a pseudocirrhosis evolution, is an unusual but lethal event that may occur during the treatment of metastatic breast cancer with Taxanes and Bevacizumab. This warns the importance of diagnostic suspicion of this pathology.

The aim of this study was to gather information on the use of stable isotopes to measure total body water and body composition scan in children. We selected studies in the last 13 years, in addition to classical studies on the subject, indexed in the database PubMed, LILACS, BVS and SciELO. The body composition was characterized by the amount of bone tissue, muscle and adipose tissue, also including the organs as well as levels of body water. Your knowledge becomes increasingly important in light of the changes that occur in the nutritional status of various types of diseases in frameworks, such as diabetes mellitus, protein energy malnutrition, in cases of obesity and metabolic syndrome. The ability to accurately assess body fat mass especially in children is associated with the importance of effective strategies for prevention and treatment of childhood obesity. Historically, in addition to clinical applications, measurements of total body water were used to determine body composition in nutritional studies. To the knowledge of the body composition, the body water can be measured and used by the ingestion of a dose of labeled water. The measured isotope enrichment is a function of the amount of body water. The method of deuterium is particularly interesting for the assessment of body composition in children, due to its characteristics of collection and analysis.

A numerical simulation study of the performance of encoding and decoding of short optical pulse in OCDMA (Optical Code Division Multiple Access) systems under non-linear optical effects is presented. The performance of encoding and decoding short pulses is obtained through use of device FBG (fiber Bragg grating) where the codes are inserted through discrete jumps in the optical phase (±π). The multiuser interference is also the object of the present study, where a figure of merit (interference figure) is used to quantify the interference in multiuser auto and cross correlation. We evaluate the dependence of the multiuser interference for the coupling constant of FBG. Finally, the interference inserted in the autocorrelation due to nonlinear effects generated in the nonlinear switching of the coded pulse in a dual core nonlinear directional coupler is examined, where temporal broadening of pulses decoded is observed.

This is an inquiry that seeks to understand the meaning of experiencing a spinal cord injury for hospitalized Brazilian and Portuguese patients. A quailtative study was achieved in two care services to spinal cord injury in Fortaleza-Brazil and Lisboa-Portugal. The subjects were 30 patients with complete spinal cord injury. The findings were obtained through a semi-structured interview, which took place at different times and it was used the following guiding question: What does it mean for you to experience a spinal cord injury? The data were organized by Bardin technique and analysis based on the assumptions of the theory of Jean Watson’s care. The speeches of the patients show a diversity of meanings such as: to lose the freedom of going and coming, sexuality and to become dependent on others. It is concluded that this situation of loss overbalances the person’s existence, which is expressed by feelings of sadness, grief, discontent, isolation, anxiety, crying, pain and emotional suffering. These feelings were expressed by the two groups despite being from different cultures. The research enabled the description of multiple dimensions of the meaning of spinal cord injury. It fills the theoretical gap, not yet sufficiently addressed to the practice of caring people with spinal cord injury.

Tamarillo (Solanum betaceum Cav. Syn Cyphomandra betacea Cav.) Sendt is a small tree native to the subtropical Andean region of South America from Colombia to Chile, popularly known as arboreal tomato, belonging to the family Solanaceae. The objective of this study was to evaluate the physicochemical characteristics of fruits and the germination of tamarillo (Solanum betaceum) seeds produced in the Caparaó-ES and MG regions. The following procedures were performed: Fruit and peel biometrics;fruit weight;pulp and peel weight;thousand-seed weight, pulp and peel yield and fruit dry mass. In the physicochemical analysis, the following parameters were determined: pH;soluble solids;titratable acidity and ratio. For the analysis of the physiological quality of the seeds, different temperatures (20°C;25°C;30°C and 20°C - 30°C) were evaluated in the presence and absence of light and the following was determined: Seed moisture content;germination;germination speed index;germination mean time;shoot length;root and total seedling dry mass. Tamarillo in the region of Caparaó-ES presents greater chemical characteristics of the fruits, germination and vigor, and in the region of Caparaó-MG presents greater physical characteristics of the fruits. Tamarillo can germinate both in the presence and absence of light, although in the presence of light, it presents greater vigor.

The search for therapeutic agents that will provide the ground for man and an improvement in their quality of life is ceaseless. The nerol (cis-2,6-dimethyl-2,6-octadien-8-ol) is a monoterpene which can be found in various medicinal plants as Lippia spp and Melissa officinalis L. The objective of this study was to analyze the acute effect of nerol in the central nervous system (CNS) by performing behavioral tests in mice (open field, elevated plus-maze, light/dark and rota rod tests). We used male albino mice (Mus musculus), Swiss variety, adult with 2 month-old. The animals were divided into five groups (n = 8) for each experimental protocol, and they were administered intraperitoneally (i.p.), respectively, Tween 80 0.05% dissolved in saline solution 0.9%, nerol (30, 60 or 90 mg/kg) or diazepam (2 mg/kg). In the open field test, all groups treated with nerol showed a significant decrease in motor activity (number of crossings, rearings and groomings) when compared with vehicle group. In the elevated plus-maze test, nerol groups significantly increased the number of entries and time of permanence in the open arms when compared with vehicle group. In the light-dark test, nerol groups showed a significant increase the time of permanence in the room clear when compared with vehicle group. In the rota rod test, the groups treated with nerol didn’t show modification in time spent and number of falls in the revolving bar when compared with vehicle group. These results indicate a possible anxiolytic effect of nerol in mice.

The use of the extraordinary hydroelectric potential of the Amazon Basin originated an increase in the offer of renewable energy in Brazil, which, in its turn, leads to conflicts and a lack of consensus among different players owing to the potential negative impacts related to the construction and operation of large hydroelectric power plants in relatively well preserved areas. In this context, environmental licensing is one of the national environmental policy’s main instruments for making decisions regarding the use of the hydroelectric potential, especially the rivers of the Amazon Basin. Nevertheless, this significant instrument has its limitations and requires adjustments in order to better aid the decision making process regarding the use of water resources and land with the goal of increasing the offer of electric energy.
