Vivências de docentes de enfermagem no ensino do cuidar

Care, in a global perspective, appears in the main quarrels as the necessary phenomenon that will have to permeate the thoughts, the perception and values for the change that will lead to the overcoming of a paradigmatic crisis. The professional care was attributed, in elapsing of history, to the Nursing. Its historical evolution and articulation with the social processes, political and scientific in prominence place, in what it says respect to human well-being, not objectifying to cure, but to comfort, to complement the weak capacities and to the establishment the present capacities, alleviating pain, in other words, caring. The Teaching of care in Nursing, suffered great influences of the biomedical model, being like this, the education in Nursing has been criticized for if being valid pedagogical models incapable to promote the growth of the subjects, keeping it passive before your life processes, showing fragilities, attitudes and questionable behaviors, dissonances, appearing the imminence of an act of to care and to educate that needs to be considered as dialectical and intersubjective act. The objective of this research is to understand the lived experience of the nursing teachers in the Teaching of Care, in order to reflect about the insert of Nursing in the current world context, watching the dialetics of the Teaching of care and the paradigm changes in the section health. It is a phenomenological research that used the analysis of the located phenomenon, to obtain the units of meaning of the speech Nursing teachers about your experience lived in the Teaching of care. This study allowed the Nursing teachers could share your existences, senses and information on the interior of your pedagogic action exalting the interpretation, which appears intentionally in the conscience, emphasizing the pure experience of the be-professor, including emotions and affectivities in the teaching of care. In the construction of the results, three moments were devoted for discussion: Multidimensional Care; Care as Professional Practice; and the Teaching of care. The speeches had revealed rich, complex and for paradoxical times. The understanding of a sensitive teaching, that sometimes, arrives if to worry in rescuing the tenderness and the humanity, it is running into the other permeated speeches of fragilities, inconstancies, technifying, that showed lacks of pedagogic preparation. The Teaching of care needs to adopt a conception of education/learning and to use methodologies that can lead to an action liberating, capable to breach with traditional mooring cables and preconceptions or little healthful habits of life, favoring the use of methods that promote educating for the way of the sensitive, detaching aspects that they contribute for this end, as the intuition, the emotion, the creation, the perception and the sensibility. In this direction, it is considered important to deepen subjects that make possible the creation of care strategies and educational with the human being vision in your totality, therefore if it perceives that the necessary therapeutical boarding to be ampler, passing for the social individual, family and its relations

Desenvolvimento de um software de comunicação sem fio aplicado à instrumentação de unidade de elevação de petróleo tipo Plunger Lift

This dissertation aims to develop a software applied to a communication system for a wireless sensor network (WSN) for tracking analog and digital variables and control valve of the gas flow in artificial oil s elevation units, Plunger Lift type. The reason for this implementation is due to the fact that, in the studied plant configuration, the sensors communicate with the PLC (Programmable and Logic Controller) by the cables and pipelines, making any changes in that system, such as changing the layout of it, as well as inconveniences that arise from the nature of the site, such as the vicinity s animals presence that tend to destroy the cables for interconnection of sensors to the PLC. For software development, was used communication polling method via SMAC protocol (Simple Medium Access ControlIEEE 802.15.4 standard) in the CodeWarrior environment to which generated a firmware, loaded into the WSN s transceivers, present in the kit MC13193-EVK, (all items described above are owners of Freescale Semiconductors Inc.). The network monitoring and parameterization used in its application, was developed in LabVIEW software from National Instruments. The results were obtained through the observation of the network s behavior of sensors proposal, focusing on aspects such as: indoor and outdoor quantity of packages received and lost, general aspects of reliability in data transmission, coexistence with other types of wireless networks and power consumption under different operating conditions. The results were considered satisfactory, which showed the software efficiency in this communication system

Análise tribológica de um sistema de acionamento alternativo de pigs para a indústria do petróleo

It is analyzed through the concepts of tribology and mechanical contact and damage the suggestion of implementing a backup system for traction and passage of Pipeline Inspection Gauge (Pig) from the inside of pipelines. In order to verify the integrity of the pipelines, it is suggested the possibility of displacement of such equipment by pulling wires with steel wires. The physical and mechanical characteristics of this method were verified by accelerated tests in the laboratory in a tribological pair, wire versus a curve 90. It also considered the main mechanisms of wear of a sliding system with and without lubricant, in the absence and presence of contaminants. To try this, It was constructed a test bench able to reproduce a slip system, work on mode back-and-forth ("reciprocation"). It was used two kinds of wires, a galvanized steel and other stainless steel and the results achieved using the two kinds of steel cables were compared. For result comparative means, it was used steel cables with and without coating of Poly Vinyl Chloride (PVC). The wires and the curves of the products were characterized using metallographic analysis, microhardness Vickers tests, X-ray diffraction (XRD), X-Ray Refraction (XRF) and tensile tests. After the experiments were analyzed some parameters that have been measurable, it demonstrates to the impracticality of this proposed method, since the friction force and the concept of alternating request at the contact between the strands of wire and the inner curves that are part ducts caused severe wear. These types of wear are likely to cause possible failures in future products and cause fluid leaks
