Study of the impact of some emotional factors related to food intake. The research is based on the design and observational cross-cultural adaptation and validation of assessment tools for emotional eating (EES-C) and eating behavior (EPI-C) in 379 non-pathological adolescents (14 -18 years old).
The factorial structure, the concurrent validity, the discriminant and reliability of the original scales were maintained. 
The girls showed a higher emotional intake in AAF in the EES-C and higher scores in DIER and EEAT in the EPI-C. The boys showed the higher scores in PAR.
We found significant differences between different types of emotional eating and sex in the AAF, and DEP subscales. A higher percentage of girls belonged to the type II and obtained the highest scores in Diet ChEAT and depressive symptoms by CDI assessment.
Diet restriction increased 3 times the risk of eating disorders, and greater parental control increased the risk of TCA twice. / Estudi de la incidència de factors emocionals relacionats amb ingesta alimentaria. Disseny descriptiu, observacional i transversal d’adaptació i validació cultural dels instruments d’avaluació de la ingesta emocional (EES-C) i de la conducta alimentària (EPI-C) en 379 adolescents no clínics (14 -18 anys). Es mantingué estructura factorial, validesa concurrent, discriminant i fiabilitat de les escales originals. Les noies presentaren major ingesta emocional en AAF i UNS de l’EES-C i puntuacions més elevades en DIER i EEAT en l’EPI-C. Els nois presentaren puntuacions més elevades en PAR. Es trobaren diferències significatives entre tipologies d’ingesta emocional en AAF, DEP i UNS i diferències de sexe. Un percentatge més elevat de noies pertanyien a la tipologia II i obtingué puntuacions més elevades en DIETA mesurada pel ChEAT i simptomatologia depressiva avaluada pel CDI. La restricció dietètica augmentà 3 vegades el risc de TCA, i un major control parental n'augmentà el risc 2 vegades.

Thesis deals with the compatibility of vehicles in a frontal collision. The first section discusses about compatibility from different views. There are the physical processes used in the mechanics of impact. The second part is focused on solving the compatibility of vehicles in a frontal collision by crash analysis using the finite element method. Firstly there are described collisions of vehicles from different vehicle classes (small cars, lower middle class, Pick up / SUV) into the fixed barrier by the US NCAP. Furthermore there are simulated head-on collisions of vehicles from different vehicle classes. In the end there is shown the possibility of using data from crash tests to determine the EES.
