The study aimed to evaluate the influence of species of cover crops on chemical and physical soil properties. The survey was conducted during the winter of 2010 and 2011 in Selvíria, Mato Grosso do Sul State, Brazil. The experimental design was a randomized block in a split plot with four replicates. The plots consisted of: millet, sun hemp, pea, velvet bean, millet + pigeon pea, millet and millet + crotalaria, and mucuna fallow. The subplots were represented by the absence of phosphate fertilizers and P2O5rates (60, 90 and 120 kg ha-1) in the form of monoammonium phosphate (MAP). The subplots that have not received phosphate fertilizer chemical and physical soil properties were analyzed. The species used as cover caused changes in the chemical and physical properties of the soil. The soil maintained with millet + black mucuna presented the highest values of P and Ca, on millet higher values of OM, pigeon higher values of K, and those under the consortium millet + pigeon had higher concentrations of Mg. The soil maintained with millet Presented lower values of density and higher values of porosity.

This work aims at studying the influence of the strain path upon the FLC0 formability parameter, the root of the forming limit curves (FLC). The investigation was conducted in an interstitial free (IF) quality steel. The FLC0 parameter was evaluated in an intrinsic tensile test in near plane strain (NPS) condition, but following two strain paths. The first one being a uniaxial (proportional) path up to initial necking. The second (non-proportional) path corresponded to applying 15 % nominal plastic strain in one direction (near plane strain) followed by a second deformation applied in the orthogonal direction up to the rupture of the samples. A reduction in the limit strains corresponding to FLC0 in the non-proportional test has been observed. The forming limit stress curves (FLSC) and the critical values FLSD0 are also related to these trajectories. A simulation using finite element method (FEM) has been applied to analyze the evolution of stress and strain during the two paths, and the results have been found consistent for both proportional and non-proportional paths. Texture and surface roughness evolution of the sheet were also measured and related to the applied strain paths. © 2015, Springer-Verlag London.

Today, though still relatively stable, the roles of carmakers and their suppliers are undergoing a period of stress caused by the increased importance and added value of electronics. Most of today's embedded systems are required to work where the characteristics of the computational load cannot always be predicted in advance. The embedded systems are, by nature, inherently real-time. Moreover, most of embedded systems work under several resource constraints, due to space, weight, energy, and cost limitations imposed by the specific application. Still timely responses to events have to be provided within precise timing constraints in order to guarantee a desired level of performance. Novel methods and tools for system-level analysis and modeling are needed not only for predictability and composability when partitioning end-to-end functions at design time (and later, at system integration time), but also for providing guidance and support to the designer in the very early stage where the electronics and software architectures of product lines are evaluated and selected. The critical architecture-evaluation and selection design-process phase affects profoundly a product line's cost, performance, and quality. The objective of this document is to present the characteristics of modern embedded applications, the problems of the current approaches and discusses the new trends.

One of the main purposes of Administration is the systematization of best practices that support the achievement of organizational objectives, mainly shareholder value in the case of for-profit companies. The aim of this study was to determine to what extent the factors identified as explanatory for achieving success in American companies were also present in Brazilian companies with similar value performance. This is a descriptive study based on field survey design. A 24-year (1988-2012) data survey of market value of all Brazilian private equity companies listed on the BM&F BOVESPA identified seven companies that met the performance parameters established in the research. Executives, or former executives, from these companies collaborated with this study, answering questions about the seven explanatory success factors identified in the research Good to Great, Collins. The adherence - or degree of alignment - observed for each factor is as follows: continuous improvement (90%); attitude toward problems (86%); strategic focus (86%); discipline (86%); leadership (82%); team (80%) and relationship with technology (78%). We conclude that, in general, the factors identified as explanatory for the high performance of American companies also significantly explain the success of Brazilian companies. This research contributes to endorse market value as a performance indicator for long-term analysis of Brazilian companies; identify Brazilian listed companies with sustained high performance; improve the understanding of strategic competitiveness factors of high performance Brazilian companies; identify possible ways to improve the performance of companies; and identify opportunities for future studies on the value of companies, competitiveness and explanatory factors.

The citriculture consists in several environmental risks, as weather changes and pests, and also consists in considerable financial risk, mainly due to the period of return on the initial investment. This study was motivated by the need to assess the risks of a business activity such as citriculture. Our objective was to build a stochastic simulation model to achieve the economic and financial analysis of an orange producer in the Midwest region of the state of Sao Paulo, under conditions of uncertainty. The parameters used were the Net Present Value (NPV), the Modified Internal Rate of Return (MIRR), and the Discounted Payback. To evaluate the risk conditions we built a probabilistic model of pseudorandom numbers generated with Monte Carlo method. The results showed that the activity analyzed provides a risk of 42.8% to reach a NPV negative; however, the yield assessed by MIRR was 7.7%, higher than the yield from the reapplication of the positive cash flows. The financial investment pays itself after the fourteenth year of activity. © 2015, Sociedade Brasileira de Fruticultura. All rights reserved.

Ecotoxicology and Environmental Safety | Year: 2014
In order to assess the safety of the carbon nanotubes to human health and the environment, we investigated the potential toxicity and ability of multi-walled carbon nanotubes (NT), to induce DNA damage by employing the Allium cepa genotoxicity/mutagenicity test and the Somatic Mutation and Recombination Test (SMART) in the fruitfly, Drosophila melanogaster. The results demonstrated that NT did not significantly induce genotoxic or mutagenic effects in the Allium cepa test. All concentrations evaluated in the SMART assay showed survival rates higher than 90percent, indicating the absence of chronic toxicity for NT. Furthermore, the various treatments showed no significant increase in the NT mutation and recombination frequencies in mwh/flr3 genotype compared to respective negative controls, demonstrating the absence of DNA damage caused by NT. © 2013 Elsevier Inc.

The performance of piezoelectric transducers is affected by variation of the acoustic loads. Correction of the excitation frequency are needed to maintain the performance. This paper presents an algorithm for dynamic correction of the operating frequency based on adaptive systems able to correct the frequency applying artificial intelligence techniques to a survey of impedance profiles. When the impedance is changed, a searching of similar values is performed in previously stored files and an iterative process finds the final frequency closer to the original impedance for the required performance. Simulations has been carried out using electric models. The results show the system is robust and the average response time is 6 ms. © 2015 The Authors.
