13. Reduction of epistemic uncertainty of a crash box model - experimental and numerical investigations
Abstract The high prediction accuracy of FEM calculations is an important prerequisite for their growing use in the field of crash load cases for vehicle body design. Although the simulation accuracy of crash calculations for steel structures already is at a high standard, continuous improvements and a further development of the simulation models are crucial

14. Recent Topics on the Structure and Crystallization of Al-based Glassy Alloys
Al-based glassy alloys (metallic glasses) have been of great scientific and technological interest as a high specific strength and high corrosion resistant materials. However, the low glass-forming ability (GFA) is still a choke point that greatly influences the applications. In order to further comprehend the glass formation mechanism and investigate the po

15. Thermal Analysis of Satellite Libertad 2: a Guide to CubeSat Temperature Prediction
ABSTRACT: We present a model for predicting the temperature of three-unit CubeSat on a low Earth orbit, which supposes a single temperature common to all satellite components. Our exposition includes a detailed, to a large extent analytical, computation of the external heat fluxes for a particular orbit and spacecraft assumptions based on the features forese

17. Applying chemometrics to predict metallurgical niobium recovery in weathered ore
Abstract Niobium metallurgical recovery measures how much of the metal content in the ore is separated in the concentrate after the mineral processing stages. This information can be obtained through laboratory tests with ore samples obtained during drilling. Thereunto, representative ore samples are subjected to tests mimicking the ore concentration process

18. Cymbopogon citratus essential oil: effect on polymicrobial caries-related biofilm with low cytotoxicity
Abstract The objective of this study was to evaluate the effects of Cymbopogon citratus essential oil and its main compound (citral) against primary dental colonizers and caries-related species. Chemical characterization of the essential oil was performed by gas chromatography/mass spectroscopy (GC/MS), and the main compound was determined. Antimicrobial act

19. Management Practices as Capabilities Leading to Superior Performance
Abstract This paper has three main contributions to the debate about the value of management practices. First, the empirical confirmation of a strong and significant relationship between the level of management practices and three major dimensions of firms' performance (profitability, growth and productivity). The value of this contribution is grounded on a

20. A Systematic Procedure to Develop a Capillary Electrophoresis Method Using a Minimal Experimental Data
The choice of an appropriate background electrolyte (BGE) and its components for capillary electrophoresis analysis is the main step in capillary electrophoresis method development. The use of an inadequate co-ion component could lead to asymmetrical peaks and selecting an inappropriate counter-ion could affect the buffer capacity and the pH of the BGE, lead

21. 3D COMPOSITIONAL RESERVOIR SIMULATION IN CONJUNCTION WITH UNSTRUCTURED GRIDS
Abstract In the last decade, unstructured grids have been a very important step in the development of petroleum reservoir simulators. In fact, the so-called third generation simulators are based on Perpendicular Bisection (PEBI) unstructured grids. Nevertheless, the use of PEBI grids is not very general when full anisotropic reservoirs are modeled. Another p

22. Cardanol-based thermoset plastic reinforced by sponge gourd fibers (Luffa cylindrica)
Abstract A growing global trend for maximum use of natural resources through new processes and products has enhanced studies and exploration of renewable natural materials. In this study, cardanol, a component of the cashew nut shell liquid (CNSL), was used as a building block for the development of a thermosetting matrix, which was reinforced by raw and mod

23. Capital social en áreas rurales: adaptación al español y validación factorial de una escala
Social capital is considered a structural determinant of social development and wellbeing. Its cognitive component assesses the degree of confidence of the population in their systems for social organization, as well as community interactions to coordinate social responses to social problems. There are few available scales for measuring this construct. This
