Abstract: background: percutaneous coronary intervention (pci) has become one of the most commonly performed cardiac procedures in clinical practice. due to improvement in outcomes, reduced acute complication rates, the need to reduce costs and the limited availability of hospital beds, elective pci with same-day discharge has become an interesting option. methods: single-center registry with a retrospective evaluation of all patients undergoing elective pci who were discharged on the same day, from january 2009 to march 2012. the rates of major adverse cardiac events (death, myocardial infarction, target-vessel revascularization and stroke), in addition to stent thrombosis, vascular complications and re-hospitalization between hospital discharge and the first 30 days of follow-up were determined. results: sixty-nine patients were evaluated with mean age of 64.5 ± 11.2 years, most of them were male (82%), and 28% were diabetics. all patients had stable coronary artery disease and type a or b1 lesions (36% and 36% respectively). radial access was the most commonly used approach (89%), with 5 f introducer sheaths in 56% and 6 f in the remaining patients. procedure success was obtained in 98.5%. no clinical events were observed at the 30-day follow-up. conclusions: our results demonstrated that same-day discharge was safe for patients with low clinical and angiographic risk undergoing elective pci with no procedure-related complications.

Abstract: the aim of this study was to identify upland rice genotypes with high stability and adaptability by the gge biplot method based on the predicted genotypic and phenotypic values. of the 20 genotypes evaluated, 14 were lines developed by the cooperative program for rice improvement of minas gerais and six were controls. the gge biplot analysis showed that cultivar brs pepita and mg1097 were closest to the ideal genotype. in the comparison of the fixed with the random models (% g + ge, prediction error sum of squares and correlation), it was observed that the use of phenotypic means in all comparative parameters indicated a lower predictive potential under simulated imbalance than the use of predicted genotypic values. the conclusion was drawn that brs pepita and mg1097 are ideal genotypes for southern minas gerais and that the predictive power of the phenotypic means underlying the study of stability and adaptability is lower than of genotypic means.

Abstract: the global positioning system (gps) transmits signals in two frequencies which allow to correct for the first order ionospheric effects through theionosphere free combination. however, the second and third order ionospheric effects which cause error of the order of centimeters in the gps measurements, still remain. these effects are, generally, neglected in the gps data processing. the first, second and third order ionospheric effects are directly proportional to the tec (total electron content) in the ionosphere, but, in the case of the second and third order effects the earth magnetic field and the maximum electron density respectively, also make a contribution. this paper investigates these two higher order ionospheric effects which were taken into account in the gps data processing in the brazilian region. the mathematical model associated with these effects will be presented, as well as the transformations involving the earth magnetic field and the use of the tec from global ionospheric maps or calculated from gps pseudorange measurements. the gps data was processed in static and kinematic relative mode and in a precise point positioning (ppp) approach. the second and third order effects were analyzed considering periods with low and high ionospheric activities. the results have shown that neglecting these effects in the precise point positioning and in the relative positioning for long baselines can cause variation of the order of few millimeters in thestations coordinates, besides diurnal variations in altitude of the order of centimeters.

International Journal of Online Engineering (iJOE) , 2012, DOI: 10.3991/ijoe.v8is4.2275
Abstract: Weblabs, or remote experimentation laboratories, make possible carrying out real-time experiments through the internet by using integrated laboratorial systems, software, hardware and multimedia resources, having important applications in engineering education and research teams cooperation. This paper presents the conceptual design of a Weblab for a thermal process plant, based on the systematic model for planning and development of Weblabs. Its approach comprises three layers (physical system, hardware and software), being prescribed the following steps: definition of requirements; system technical specification; conceptual synthesis; analysis, simulation and dimensioning; detailing and documentation; integration and start up test. The users (qualitative) and project (technical, quantitative) requirements have been compiled in a previous work through the application of the House of Quality matrix from the QFD method. The functional structure, the morphological chart and the use of Pugh's method to select the best design solution, as well as a description of the developed conceptual solution, are presented. The conceptual solution includes the thermal process plant remote configuration to allow the variation of the experimental setup parameters, offering three variants of control engineering exercises. The presented results provide the basis for the next stage of the Weblab development.

Abstract: Given the quest for sustainable development and rational use of resources natural, the implementation of irrigation systems becomes a necessity in regions of seasonal scarcity of water and great agricultural productivity, as in case of Paraná. Thus, the objective was to evaluate the parameters Physico-chemical water quality in the city of Salto do Lontra –Paraná. The Physical-chemical analysis included: pH, Electrical Conductivity (EC), Total Solids Soluble (STS), nitrate (N-NO3), RAS, Sodium (Na++), chlorine (Cl-) and bicarbonate (HCO3), being held in 40 properties, according to APHA (1998). The analysis Statistical surveys were performed using the Minitab 15 software. The results in the study period, showed average values in the range limits recommended by FAO for the use ofirrigation water considering all parameters measured and there was no restrictions on water use in irrigation.

Abstract: In Front of new prospects and the environmental concerns with sustainable development, always more the science, communities, institutions of education and general managers have been engaged in developing new strategies and methodologies to work in urban and rural area. The aims are not harming the environment and optimize the processes of action, trying to maximize profits. The objective of this study was to verify the current state of knowledge of environmental education and dissemination of information on subsistence agriculture, within the national context. The methodology was based on a qualitative literature review, with exploratory character, exposing the main arguments used and their applicability. The results showed that although there are many options to work for environmental education in family agriculture, few things has been done in practice. It was verified that the main focus of environmental education in the field is restricted to activities with planting of seedlings for reforestation of degraded areas and conservation of riparian forests. Although, the environmental education may involve several techniques aimed at improving the quality of life in the field. Also, working only with "green marketing" themes are not that interesting, when we talk about sustainability.

PCBs, polychlorinated biphenyls (polychlorinated biphenyls), are the generic names given to the class of organochlorine compounds resulting from the reaction of the biphenyl group with anhydrous chlorine in the presence of a catalyst. They are toxic, persistent, bioaccumulative and pose the risk of causing harm to human health and the environment. Large quantities of PCBs were produced in several countries between 1927 and 1977. In the United States the prohibition occurred in 1977. Due to high toxicity, production and marketing of PCBs have been banned worldwide since 1980. It was carried out at the Chemistry Institute of Sao Carlos—University of Sao Paulo, and developed a procedure for decontamination of mineral insulating oil containing PCBs values above 50 mg/kg. In the procedure, the contaminated oil was passed by percolation in a column containing polyurethane foam derived from vegetable oil, produced by the Laboratory of Analytical Chemistry and Polymer Technology (GQATP), thus obtaining a 55% reduction in the levels of PCBs.
