We found an increased risk for breast cancer in the leaner women, especially in the leaner postmenopausal subgroup, related to the TEXB-alpha. The pesticides aldrin and lindane are also individually associated with risk.

Currently, the use of virtual reality (VR) is being widely applied in different fields, especially in computer science, engineering, and medicine. Concretely, the engineering applications based on VR cover approximately one half of the total number of VR resources (considering the research works published up to last year, 2016). In this paper, the capabilities of different computational software for designing VR applications in engineering education are discussed. As a result, a general flowchart is proposed as a guide for designing VR resources in any application. It is worth highlighting that, rather than this study being based on the applications used in the engineering field, the obtained results can be easily extrapolated to other knowledge areas without any loss of generality. This way, this paper can serve as a guide for creating a VR application.

This study aims to evaluate the effect of laser irradiation and orthophosphoric acid etching on the shear bond strength (SBS) of orthodontic brackets to enamel. Three groups (n = 20) of extracted premolar teeth were randomly established depending on the laser treatment performed on the buccal surfaces: (1) no laser (control); (2) Er:YAG laser (2,940 nm, 0.8 W, 100 μs/pulse, 10 Hz) and; (3) Ti:Sapphire laser (795 nm, 1 W, 120 fs/pulse, 1 kHz). Each group was divided into two subgroups according to whether 37%-orthophosphoric acid etching was made after laser irradiation or not. Brackets were randomly luted with Transbond(TM) XT adhesive resin. After 72 h, a SBS test was developed in a universal testing machine (crosshead speed, 0.5 mm/min). Representative specimens from each experimental subgroup were examined by means of scanning electron microscopy. Cement residuals remaining on the premolar surfaces were assessed using the adhesive remnant index. ANOVA, post-hoc tests for intergroup comparisons, chi-square test and linear regression were run for data analyses (α = 0.05). After acid etching, SBS values did not differ regardless the laser treatment. When phosphoric acid was not applied, the SBS values of the femtosecond laser group were significantly higher than for the other groups. Femtosecond laser without acid seems to be the most suitable method to improve bond strengths at the bracket/enamel interface, thus avoiding the disadvantages inherent to acid etching.

Resumen. En España, a partir de la entrada en vigor de la Ley Orgánica 1/2004 de Medidas de Protección Integral contra la Violencia de Género, los programas de intervención para maltratadores se han convertido en un recurso necesario para el cumplimiento de las suspensiones de condena condicionadas, en casos de violencia de género. El objetivo de este artículo es presentar el trabajo realizado desde el Programa Contexto (Universidad de Valencia) en el ámbito de la investigación, formación e intervención con penados por violencia de género. En primer lugar, se describen las principales características y líneas directrices de la intervención en el Programa junto con la estructura y fases de la misma. En segundo lugar, se detalla el proceso de formación establecido para los colaboradores en el programa y las actividades de formación desarrolladas por parte de los miembros del equipo. Por último, se presentan las principales líneas de investigación que están orientando el trabajo del equipo que forma parte del Programa Contexto, así como algunos resultados preliminares.

In Spain, after the coming into force of Organic Law 1/2004 (Integral Protection Measures against Gender Violence) intervention programs for perpetrators of domestic violence have become necessary for the application of conditional suspended sentences in cases of gender violence. The aim of this paper is to present the work done in the Programa Contexto (University of Valencia) in the field of research, training and intervention in those convicted of domestic violence. Firstly, we describe the main characteristics and guidelines for intervention in the program, in conjunction with its structure and different phases. Secondly, the training process provided for volunteers on the program is described, and the training activities developed by the team members. Finally, we present the main lines of research that are guiding the work of the team that is part of Programa Contexto and the preliminary results.
