Capacidade de suporte de carga de Latossolo Vermelho cultivado com cana-de-açúcar e efeitos da mecanização no solo

The objective of this work was to determine the load support capacity (LSC) of an Oxisol and, through compressibility models, relate it to wheel-soil interactions under management systems with one and three sugarcane crop cycles, with mechanized harvest. LSC evaluations were carried out on undisturbed soil samples, collected at planting row and bed, in four layers: 0.00-0.10, 0.10-0.20, 0.20-0.30, and 0.300.40 m. The contact area between wheels and soil was determined in order to estimate the contact pressure by agricultural machinery on the soil. Pre-consolidation pressures were used to determine LSC. The system with three cycles showed higher LSC than the system with only one cycle. The load support capacity of the soil evaluated in the range of friability is greater than the contact pressures applied to the soil by the wheels of the studied agricultural machines.

Influence of occlusal contact area on cusp defection and stress distribution

The purpose of this study was to evaluate the effect of occlusal contact area for loading on the cuspal defection and stress distribution in a first premolar restored with a high elastic modulus restorative material. The Rhinoceros 4.0 software was used for modeling the three-dimensional geometries of dental and periodontal structures and the inlay restoration. Thus, two different models, intact and restored teeth with three occlusal contact areas, 0.1, 0.5 and 0.75 mm(2), on enamel at the occlusal surface of buccal and lingual cusps. Finite element analysis (FEA) was performed with the program ANSYS (Workbench 13.0), which generated a mesh with tetrahedral elements with greater refinement in the regions of interest, and was constrained at the bases of cortical and trabecular bone in all axis and loaded with 100 N normal to each contact area. To analysis of maximum principal stress, the smaller occlusal contact area showed greater compressive stress in region of load application for both the intact and inlay restored tooth. However, tensile stresses at the occlusal isthmus were similar for all three tested occlusal contact areas (60 MPa). To displacement of the cusps was higher for teeth with inlay (0.46-0.48 mm). For intact teeth, the smaller contact area showed greater displacement (0.10 mm). For teeth with inlays, the displacement of the cusps were similar in all types of occlusal area. Cuspal displacement was higher in the restored tooth when compared to the intact tooth, but there were no significant variations even with changes in the occlusal contact area. RELEVANCE CLINICAL: Occlusal contacts have a great influence on the positioning of teeth being able to maintain the position and stability of the mandible. Axial loads would be able to generate more uniform stress at the root presenting a greater concentration of load application in the point and the occlusal surface. Thus, is necessary to analyze the relationship between these occlusal contacts as dental wear and subsequent occlusal interferences.

Design de Relações entre tecnologias amigáveis e sociabilidades virtuais: um novo campo de investigação para o Design

The Digital Age, with its new interactive and converging technologies, stimulates original forms of sociability, which are interconnected, intercommunicating and virtualized through hyperscreens. Another kind of interaction arises from the digitization and new speeds of contemporary communicative process. With the new order of knowledge, it is now possible to transgress the limits of physical space and linear time sequence, through the collective development of content through such telematics networks. Youth gives voice to a new type of user, or a social actor, whose thinking is connected to other communication habits, consolidating singular cultural standards, demanding new languages and skills. Here, we address the nature of this Design of new relations, interactions, behaviors and social systems that emerge in the so called Information Society.

Televisão Digital: novos meios, novas narrativas

Grandes mudanças de ordem tecnológica e social colaboraram para a transformação na forma de comunicação do homem ao longo da história, que compartilha informações e transforma conceitos através de novos meios e novas narrativas, construindo e reconstruindo informações. O compartilhamento desses novos conteúdos vem colaborar na divulgação de diversidades culturais e regionais de todo o país fazendo jus a um dos objetivos da televisão digital que é a democratização da informação e do conhecimento.

The journey to sustainable universities: insights from a Brazilian experience

Universities play a key role in humanity’s search for sustainable development. This paper presents the results of preliminary studies on projects regarding campus sustainability, conducted at Universidade Estadual Paulista ‘Julio de Mesquita Filho’ – UNESP’s Bauru Campus, State of São Paulo. It recommends the constitution of a sustainability committee, with a public participation and social responsibility (PPSR) framework, and the implementation of a campus sustainability program. The study also describes how social responsibility and sustainability can bring UNESP/Bauru economic advantages.

Encefalopatia hepática: relatório da 1º reunião monotemática da Sociedade Brasileira de Hepatologia

Hepatic encephalopathy (HE) is a functional disorder of the central nervous system (CNS) associated with liver failure, either end-stage chronic liver disease or fulminant hepatic failure. Its pathogenesis remains complex and poorly understood. In view of recent advances in the management of HE, the Brazilian Society of Hepatology endorsed a monothematic meeting regarding HE in order to gather experts in the field to discuss related data and to draw evidence-based recommendations concerning: management of HE and intracranial hypertension in FHF, treatment of episodic HE in cirrhosis, controversies in the management of EH including difficult to treat cases and diagnostic and treatment challenges for minimal HE. The purpose of this review is to summarize the lectures and recommendations made by the panel of experts of the Brazilian Society of Hepatology.

Acetylcysteine for Prevention of Renal Outcomes in Patients Undergoing Coronary and Peripheral Vascular Angiography Main Results From the Randomized Acetylcysteine for Contrast-Induced Nephropathy Trial (ACT)

Background-It remains uncertain whether acetylcysteine prevents contrast-induced acute kidney injury. Methods and Results-We randomly assigned 2308 patients undergoing an intravascular angiographic procedure with at least 1 risk factor for contrast-induced acute kidney injury (age >70 years, renal failure, diabetes mellitus, heart failure, or hypotension) to acetylcysteine 1200 mg or placebo. The study drugs were administered orally twice daily for 2 doses before and 2 doses after the procedure. The allocation was concealed (central Web-based randomization). All analysis followed the intention-to-treat principle. The incidence of contrast-induced acute kidney injury (primary end point) was 12.7% in the acetylcysteine group and 12.7% in the control group (relative risk, 1.00; 95% confidence interval, 0.81 to 1.25; P = 0.97). A combined end point of mortality or need for dialysis at 30 days was also similar in both groups (2.2% and 2.3%, respectively; hazard ratio, 0.97; 95% confidence interval, 0.56 to 1.69; P = 0.92). Consistent effects were observed in all subgroups analyzed, including those with renal impairment. Conclusions-In this large randomized trial, we found that acetylcysteine does not reduce the risk of contrast-induced acute kidney injury or other clinically relevant outcomes in at-risk patients undergoing coronary and peripheral vascular angiography.
