13. Numerical and experimental investigation of forming limit diagrams of 6063 aluminum alloy sheets using Ayada ductile fracture criterion and the second derivative of large strain criterion at increased temperatures
Abstract The present study investigated the forming limit diagrams (FLDs) of aluminum alloy 6063 sheets using numerical and experimental methods at increased temperatures. In the numerical section, for the first time, the Ayada ductile fracture criterion and the second derivative of the large strain criterion were used. ABAQUS finite element (FE) analysis so

14. Algunas precisiones acerca de la filosofía moral experimental de David Hume
ABSTRACT Even though there is a general agreement among the scholars concerning the relationship between Hume and experimental philosophy, yet important disagreements prevail regarding the subject of the “science of human nature,” as well as the reasons that ground the introduction of the experimental method into moral subjects, and the way in which Hume

15. Scientometric indicators for Brazilian research on High Energy Physics, 1983-2013
ABSTRACT This article presents an analysis of Brazilian research on High Energy Physics (HEP) indexed by Web of Science (WoS) from 1983 to 2013. Scientometric indicators for output, collaboration and impact were used to characterize the field under study. The results show that the Brazilian articles account for 3% of total HEP research worldwide and that the

17. Heart disease and the stress hypothesis in the mid-twentieth century: a historical review
Abstract Background In the 1920s, heart disease (a noncommunicable disease), was the new leading cause of death in the USA. Simultaneously, experimental progress in the study of stress provided scientific justification for a new type of risk factor. The objective of the present work is to examine the history of heart disease as a public health problem and

18. Review on research of the phytochemistry and pharmacological activities of Celosia argentea
ABSTRACT Celosia argentea L., Amaranthaceae, is widely used as traditional medicine with a long history in China. It is a unique source of Semen Celosiae whose contributions include purging the hepatic pathogenic fire, improving eyesight, and treating other eye diseases. Over 79 compounds from this plant were isolated and identified, mainly including saponin

19. Experimental Investigation on Limit Cycle Wing Rock Effect on Wing Body Configuration Induced by Forebody Vortices
ABSTRACT The purpose of this paper is to present the aerodynamic and flow characteristics of a slender body with a 30° swept wing configuration undergoing a limit cycle oscillation using a synchronous measurement and control technique of wing rock/particle image velocimetry/dynamic pressure associated with the time history of the wing rock motion. The exper

20. 12 mm Thick Circular Blanks of Al-killed AISI 1020 Steel -Applied for Cylindrical Cup Manufacturing by Multistage Deep Drawing with Simultaneous Ironing
Abstract In this paper a new modified processing route has been proposed for producing long cylindrical cups from 12 mm thick circular blanks of AISI 1020 steel (Aluminium (Al) -killed). In this route, flat blanks were made to preformed shape by stamping operation, followed by multistage deep drawing processes(without blank-holder and with inter-stage stress

23. Epigénesis y preformacionismo: radiografía de una antinomía inconclusa
ABSTRACTThe process of development of the embryo has inspired philosophical speculation since the advent of Western thought. Since the time of Aristotle two antithetical conceptual models have traditionally been used to understand embryogenesis: either form or structure is preformed in the embryo or it is newly formed with each generation. Our aim in this ar

24. Motor, linguistic, personal and social aspects of children with Down syndrome
AbstractA global developmental delay is expected from Down syndrome, affecting motor, cognitive, linguistic and personal-social skills. However, not always these delays are proportional; different conditions occur due to several intrinsic and extrinsic variables that must be controlled to form groups of greater homogeneity.Objective To enhance personal-socia
