16. Trabajando juntos situaciones introductorias de razonamiento proporcional en primaria. Análisis de una experiencia de enseñanza centrada en el profesor, en el estudiante y en el contenido
Abstract Although there is a fairly generalized consensus in mathematics education in favour of constructivist-type instructional models, their pertinence is controversial. Between the extreme centered models, either on the student or on the teacher, we find other mixed type models, where both educational process agents play a leading role, depending on the

18. A direct technique for the homogenization of periodic beam-like structures by transfer matrix eigen-analysis
Abstract To homogenize lattice beam-like structures, a direct approach based on the matrix eigen- and principal vectors of the state transfer matrix is proposed and discussed. The Timoshenko couple-stress beam is the equivalent continuum medium adopted in the homogenization process. The girders unit cell transmits two kinds of bending moments: the first is g

19. Synthetic phosphoethanolamine: the state of the art of scientific production
ABSTRACT Cancer is a multifactorial disease and a serious public health problem. Currently, alternative drug treatments for cancer are actively being sought, which is the case of synthetic phosphoethanolamine (PHOS-S), a compound that could possibly have anticarcinogenic effects. To analyze the available scientific evidence to evaluate the anticarcinogenic e

20. Radiotherapy modulates expression of EGFR, ERCC1 and p53 in cervical cancer
Cervical cancer is a public health problem and the molecular mechanisms underlying radioresistance are still poorly understood. Here, we evaluated the modulation of key molecules involved in cell proliferation, cell cycle and DNA repair in cervical cancer cell lines (CASKI and C33A) and in malignant tissues biopsied from 10 patients before and after radiothe

21. A novel transition identification mechanism for the diesel blending and distribution scheduling problem using the discrete time representation with two time-scales granularity
ABSTRACT Transitions between tasks arise in many different scheduling problems. Sometimes transitions are undesired because they incur costs; sometimes they are undesired because they require setup time, and sometimes both. In one way or the other, frequently, transitions need to be identified and penalized in order for their frequency to be minimized. The p

22. Analysis of reverse heat transfer for conventional and optimized lubri-cooling methods during tangential surface grinding of ABNT 1020 steel
Abstract A numerical thermal model was developed to evaluate the heat flux which is conducted to a rectangular workpiece of steel plate ABNT 1020, thus making it possible to compute the maximum temperature in the grinding surface, taking into account the rectangular distribution of heat flux, the thermal properties of the grinding wheel conventional Al2O3, t

23. Crack Detection Using Mixed Axial and Bending Natural Frequencies in Metallic Euler-Bernoulli Beam
Abstract For many years, several crack detection attempts have been using measurements of the structure's modal parameters. One of the easiest is to measure and correlate the change in natural frequencies to cracks. The direct and inverse problem have been discussed in literature. However, the inverse problem, being addressed in this paper, is a challenging

24. A Differential Quadrature Procedure with Direct Projection of the Heaviside Function for Numerical Solution of Moving Load Problem
Abstract Owing to its particular characteristics, the direct discretization of the Dirac-delta function is not feasible when point discretization methods like the differential quadrature method (DQM) are applied. A way for overcoming this difficulty is to approximate (or regularize) the Dirac-delta function with simple mathematical functions. By regularizing
