The burn is among the leading causes of morbidity and mortality in our society. It shows a great complexity and is hard to treat. Beyond the physical suffering, the burned patient is affected by psychological distress, requiring a high level of knowledge for assistance planning. The Professional Practice Law No. 7498 establishes the nurse as in charge of the client, as leader of the nursing team and as responsable for the management of physical and human resources. The nurse has autonomy to design the quantitative and qualitative picture of the nursing staff and should use the methodologies for their suitability to the real levels of assistance needed. Material resources represent 15 to 25% of total expenditures at health organizations. Therefore, to maintain the care level, nurses must determine the needs, considering the quantitative, qualitative and financial aspects. The study aimed the survey of the human and material resources necessary for nursing care to patients in a Burns Treatment Unit and identify its epidemiological profile and its nursing diagnoses. We collected the data from medical records of hospitalized between July and August, and the nursing diagnoses were classified through the Taxonomy II proposed by the North American Nursing Diagnosis Association (NANDA). The design of the picture of nurses followed the parameters of COFEN Resolution nº 293/2004. We apply the Fugulin's Patients Classification System to establish levels of the required care. The institution's Cost Center provided a spreadsheet with the purchased items, subsequently classified into ABC. Most hospitalized patients were men, aged between 20 and 50. There was a predominance of patiences with minor burned and the most common type of burn was due to fire. The average residence time was 28.71 days, and 88% of the patients were discharged...

We discuss in the work the importance of experiential activities for Physics Teaching in the first years at Elementary Education. For this we start from the experience provided by the Teaching Project Initiation under Pibid CAPES, linked to the Department of Education from the Institute of Biosciences and activities of the Graduate Diploma in Physics Supervised, at Rio Claro Campus, São Paulo State, in partnership with Basic Education schools of the city. Based on some patterns and studies on the Teaching of Science in Elementary Education and particularly in the Ferreira’s work with Instrumentation for Physics Teaching, Electrostatic was chosen as base theme. We opted for the use of didactic experiments that provided in its construction the utilization of low cost materials, easy access and portability. Teaching strategies were aimed at inserting experiential activities during Elementary School I (first and third years of elementary school), intending to rescue the trial of Physics Education and Science for Basic Education. These experimental teaching activities were analyzed in this paper from the perspective of playfulness. We argue that experimentation with recreational attributes when properly used provides the interaction of individuals with the knowledge of Physical Sciences

The small angle X-ray scattering (SAXS) technique has been used with very much versatility and success in the structural characterization of nanostructured materials. The present work deals with a study of the principles of the SAXS technique and of some classical models employed in the structural characterization of nanostructured materials. Particularly, the study of the models and of the associated methodologies is applied to a set of samples of silica gels, of varied typical structures, prepared in the Laboratório de Novos Materiais of the Departamento de Física of the IGCE. The work discusses in an introductory chapter the principles of the SAXS technique and the foundation of classical models often used in the structural characterization of materials. The classical models and the associated methodologies were applied to a variety of silica gel structures. The studies include: i) the scattering from a system of particles - Guinier's law; ii) the asymptotic scattering from a two-phase system - Porod's law; iii) systematic deviation from Porod's law - Surface Fractal; iv) heterogeneities in solids with random size distribution - DAB Model; and v) the scattering from mass fractal structures. The analyses were carried out from experimental SAXS data obtained in several opportunities at the Laboratório Nacional de Luz Síncrotron (LNLS)

The use of polymeric materials has grown in recent years due to its high durability features, atoxicity, shaping versatility and environment resistance. However, while these features represent good advantages to several industry sectors, it results in one of the most serious environmental problems of contemporary society: the rising accumulation of these material, mainly due to the inadequate disposal of waste. Meanwhile, in order to minimize this problem, some mitigation techniques comes up (arises), among which the use of biodegradable polymers has been gaining attention. Because of their easily action of microorganisms, such material degrade more rapidly, becoming integrated to nature. Furthermore, due to the fact of biodegradation is a natural process, occurring through the action if micro-organisms in the environment itself, it is considered the “cleaner” alternative found so far to plastic components reincorporation in the nature. Among the micro-organisms capable of biodegradation process are the filamentous fungi. These micro-organisms have many advantages over the others, the major one being the capacity to produce a range of enzymes capable of degrading different materials. In this context, the present review made it possible to see the importance of this process as an agent of environmental preservation, suggest the use of blends to minimize the problems of cost and flexibility of biodegradable polymeric materials, as well as noting the lack of studies related to this subject nowadays
