With the trajectory that the problems related to child health are taking in our society, particularly with regard to infant mortality, beyond the process of decentralization of health and the implementation of the Family Health Strategy in the cities, where it has increased considerably performance of nursing staff in Primary Health Care, they can be considered essential factors for reflections on the care of nurse dispenses the health of these children. In order to check how it is organized the working process of the nurse in caring for these children in USFs as well as the difficulties found in the dynamics of this work, this research aimed to analyze the work processes of nurses in care Child Health in USFs, with emphasis on technologies used in producing care. This is a research exploratory and descriptive with qualitative approach, based on the theoretical reference in about Work Process and Composition Technique of Work. The data were collected through semi-structured interviews of 11 nurses who, at the moment, perform their functions for more than 01 year at USF. The guiding questions were based at theoretical reference. To analyze the results, was used the referential of content analysis, and was refer to thematic analysis. In situations that were involved closed questions of the interview, was used the aid of SPSS 15.0 program for Windows. The results indicated that the process of nurse work in health care of children, focuses on the preventive character, whose focus of the actions are healthy children, following the routines and protocols established by the Ministry of Health with a view to maintaining health them. When analyzing the data through theoretical references of Composition Technique of Work found that the core technologies of daily tasks of the nurse are directed for the use of technology soft-hard and hard, and the reason established between the Dead Working and Alive Working, there is prevalence of the first against the second in the production of this care. These situations contribute to the explanation of the emergence problems related to adhesion of mothers / caregivers to monitoring the CD, due to character prescriptive and normalizer of actions. The results also suggested the presence of "vanishing lines" in the make of nurses, confirming the self-governance of health professionals in daily work. These "vanishing lines" express the own execution of the Work Live in action, guided by the use of soft technologies, however, was not characterized as a process of technology transition. So, to get a better resolution to the problems related to child health, the nurse has reorganize your work process by focusing on the execution of work live in action.

This work presents a model of bearingless induction machine with divided winding. The main goal is to obtain a machine model to use a simpler control system as used in conventional induction machine and to know its behavior. The same strategies used in conventional machines were used to reach the bearingless induction machine model, which has made possible an easier treatment of the involved parameters. The studied machine is adapted from the conventional induction machine, the stator windings were divided and all terminals had been available. This method does not need an auxiliary stator winding for the radial position control which results in a more compact machine. Another issue about this machine is the variation of inductances array also present in result of the rotor displacement. The changeable air-gap produces variation in magnetic flux and in inductances consequently. The conventional machine model can be used for the bearingless machine when the rotor is centered, but in rotor displacement condition this model is not applicable. The bearingless machine has two sets of motor-bearing, both sets with four poles. It was constructed in horizontal position and this increases difficulty in implementation. The used rotor has peculiar characteristics; it is projected according to the stator to yield the greatest torque and force possible. It is important to observe that the current unbalance generated by the position control does not modify the machine characteristics, this only occurs due the radial rotor displacement. The obtained results validate the work; the data reached by a supervisory system corresponds the foreseen results of simulation which verify the model veracity

The vehicles are the main mobile sources of carbon monoxide (CO) and unburned hydrocarbons (HC) released into the atmosphere. In the last years the increment of the fleet of vehicles in the municipal district of Natal-RN it is contributing to the increase of the emissions of those pollutants. The study consisted of a statistical analysis of the emissions of CO and HC of a composed sample for 384 vehicles with mechanization Gasoline/CNG or Alcohol/Gasoline/CNG of the municipal district of Natal-RN. The tests were accomplished in vehicles submitted to Vehicular Safety's Inspection, in the facilities of INSPETRANS, Organism of Vehicular Inspection. An partial gases analyzer allowed to measure, for each vehicle, the levels of CO and HC in two conditions of rotation of the motor (900 and 2500 rpm). The statistical analysis accomplished through the STATISTICA software revealed a sensitive reduction in the efficiency of the converters catalytic after 6 years of use with emission average it is of 0,78% of CO and 156 (ppm) of HC, Which represents approximately 4 (four) times the amount of CO and the double of HC in comparison with the newest vehicles. The result of a Student s t-test, suggests strongly that the average of the emissions of HC (152 ppm), at 900 rpm, is 40% larger than at 2500 rpm, for the motor without load. This result reveals that the efficiency of the catalytic conversion is limited kinetically in low engine speeds. The Study also ends that when comparing the emissions of CO and HC considering the influence of the fuels, it was verified that although the emissions of CO starting from CNG are 62% smaller than arising from the gasoline, there are not significant differences among the emissions of HC originating from of CNG and of the gasoline. In synthesis, the results place the current criteria of vehicular inspection, for exhaust gases, in doubt, leading the creation of emission limits of pollutant more rigorous, because the efficiency of the converters catalytic is sensibly reduced starting from 6 years of use. It is also raised the possibility of modifications in the test conditions adopted by the current norms, specifically in the speed engine, have seen that in the condition without load the largest emission indexes were registered in slow march. That fact that allows to suggest the dismissal of the tests in high speed engine, reducing the time of inspection in half and generating economy of fuel

This work is combined with the potential of the technique of near infrared spectroscopy - NIR and chemometrics order to determine the content of diclofenac tablets, without destruction of the sample, to which was used as the reference method, ultraviolet spectroscopy, which is one of the official methods. In the construction of multivariate calibration models has been studied several types of pre-processing of NIR spectral data, such as scatter correction, first derivative. The regression method used in the construction of calibration models is the PLS (partial least squares) using NIR spectroscopic data of a set of 90 tablets were divided into two sets (calibration and prediction). 54 were used in the calibration samples and the prediction was used 36, since the calibration method used was crossvalidation method (full cross-validation) that eliminates the need for a validation set. The evaluation of the models was done by observing the values of correlation coefficient R 2 and RMSEC mean square error (calibration error) and RMSEP (forecast error). As the forecast values estimated for the remaining 36 samples, which the results were consistent with the values obtained by UV spectroscopy

From the second half of the twentieth century the state bega n to use exaction beyond your fiscalist character, also as a means of alignment deformities economic and social balance, influencing in different directions, according to economic, social and political policy. It is what is usually called the extrafiscalit y. It is in light of this phenomenon and the constitutional perspective, the present work aims to analyze item IV of article. 8 of Law n. 6.967/96, regulatory Property Tax Vehicle Automotive (property taxes) in the State of Rio Grande do Norte, in view of its possible incompatibility with the principles of the Basic Statute and with international guidelines for protection of the environment The problem of this research is Seated in art. 225 of the Constitution, which provides that everyone has the right to an ecologically balanced environment. From the reading of this standard, extracted it is the responsibility of the state protecting the environment, which requires the adoption of suitable actions to that end. However, we look to state law cited follows th e constitutional path, since it exempts the collection of property taxes automotive vehicles with over 10 years of manufacturing, which could encourage the conservation of a fleet of old vehicles, mostly more polluting and harmful to the environment and hu man health. Would the state legislature oblivious to the constitutional principles and the global trend of environmental preservation? Thus questions whether such an incentive for more polluting vehicles, emitting more gases in the atmosphere. Moreover, th e international community is already moving through important conventions in an attempt to minimize and control global warming and climate change. Predicting the theme in CF/88 demonstrates that the country is no stranger to the issue. Thus, the work is a retelling of Law No. 6.967/96 order to check whether it is compatible with the existing system. The methodology consists of a documentary, deductive, dialectical literature. At the end of the survey, it was found that provide a tax benefit to these vehicle s is encouraged to maintain them in circulation and contribute to the increase in air and noise pollution, in addition to the traffic problems generated. Thus, this potiguar anything standard can be expressed extrafiscality because the medium and long term there is encouragement and worsening environmental problem. Despite the ability to pay clause, but this remission is an affront to legally protected interests. Thus, this device goes in reverse order compared to the values of the legal system and in relat ion to sustainable development. Modern Tax Law should be used as a tool to achieve the purposes collimated by the State, and not otherwise. It was noticed that the vast majority of Brazilian states does not follow this rule, including Mato Grosso and Minas Gerais have no such exemption. Therefore, the RN State does not constitute a model for sustainable public policies, nor example of environmental protection by state law.

The Federal Constitution, in Article 1, sections III and IV, lifted the work as the foundation of the Federative Republic of Brazil, including work as a social guarantee in Article 6, listing in its Article 7 minimal guarantees role with respect to social rights of workers. Although elevated to constitutional rights, these social rights of workers have in the judicial interpretation of the characteristic elements of the employment relationship, sometimes a mismatch with the legal and constitutional order, when, in deciding not ponder such elements, causing damage economic and social benefits to all workers, thus affecting the very constitutional basis of worker protection, there is therefore situations in which there must be part of unavailability of rights by the employee. Therefore, identifying the characteristic elements of employment, means allow immediate legal finding about possible illegality perpetrated by the employer, precisely because the sentence recognizes be merely declaratory noting, therefore, the elements that make up the juridical system normative in order to establish the characterization of employment in step with the effective observance and guarantee of social rights and therefore the employer's performance limiter as pertains to hiring and employee dismissal. This point is it's main element of this work, which is fundamental for the exegesis of the theme to limit the autonomy of the will. There is no denying, therefore, the need to extend the effects of these guarantees in the employment contract. In this context, therefore, jumping the guarantees of employees, embodied in particular in the Consolidation of Labor Laws, and especially in the Federal Constitution and international protection instruments to ensure the fundamental right to secure employment relationship, where technological advancement, social and economic, reflect directly, such as the parassubordinação, and claiming more and more systematic resolutions, especially when evidence gaps' values, which elevate the debate about the need for increased use of precedents of order to support the judgments, often beset with aspects of unconstitutionality, all in compliance with the integration of standards, seeking legal enforcement of this bond and providing legal certainty, there emerged, so the essence of the theme: discuss to what extent the distortion of employment limits the effectiveness of social rights and what its legal effects, since the constitutional standard for social guarantees protects equally worker admission.

The constant necessity for new sources of renewable energy is increasingly promoting the increase of investments in this area. Among other sources, the wind power has been becoming prominent. It is important to promote the search for the improvement of the technologies involved in the topologies of the wind turbines, seeking for alternatives which enhance the gotten performance, despite the irregularity of the wind speed. This study presents a new system for speed control, in this case applied to the wind turbines - the Electromagnetic Frequency Regulator (EFR). One of the most used devices in some topologies is the mechanical gearboxes which, along with a short service life, often represent sources of noise and defects. The EFR does not need these transmission boxes, representing a technological advancement, using for that an adapted induction machine, in which the stator becomes mobile, supportive to the axis of the turbine. In the topology used in this study, the EFR also allows us to leave out the usage of the eletronic converters to establish the coupling between the generator and the electrical grid. It also the reason why it provides the possibility of obtaining the generation in alternating current, with constant voltage and frequency, where there is no electrical grid. Responsable for the mechanical speed control of the generator, the EFR can be useful in other transmission systems in which the mechanical speed control output is the objective. In addition, the EFR operates through the combination of two inputs, a mechanical and other electrical. It multiplies the possibilities of application because it is able to synergistic coupling between different arrays of energy, and, for such reasons, it enables the various sources of energy involved to be uncoupled from the network, being the synchronous generator responsible for the system connection with the electrical grid, simplifying the control strategies on the power injected in it. Experimental and simulation results are presented through this study, about a wind turbine, validating the proposal related to the efficience in the speed control of the system for different wind conditions.
