Young women still have a lower entrepreneurial inclination (EI) than young men in both a Latin society (Spain) and in a Nordic society (Iceland). Our data come from a survey conducted among university students who attended the Complutense University of Madrid and the University of Iceland. After constructing a set of variables and indicators that served as explanatory variables, and after conducting a statistical and regression analysis, this study provides evidence about the determinants of this gender gap in EI. The EI of male students was more sensitive to having higher self-confidence than in the case of female students. In turn, the EI of female students was more sensitive to both positive (enrichment) and negative (conflict) perspectives about the work–family interface than in the case of males. Additionally, the EI of students was positively related with entrepreneurial family antecedents, and with the level of parental income; and it was negatively related with their tolerance for risk. Some cross-cultural differences were also found between the Spanish and Icelandic samples.

The development and validation of a modular composite impact structure is presented in the present paper. Quasi-static and dynamic impact tests of the composite components and a full frontal crash test of a vehicle prototype with composite impact structures manufactured by a new UV-pultrusion process have been performed. The results have demonstrated the feasibility of composite impact structures for crash applications with high specific energy absorption values compared with current metallic crash structures. Furthermore, due to the high production capacity of this new manufacturing process, cost-effective composite impact structures for mass-production of conventional cars may be feasible. Finally, a multimaterial numerical model as design tool for crashworthiness applications has also been validated. Different accelerations measured in the crash test have been accurately predicted as well as the crash behaviour of the composite impact structures.

The heating produced by the absorption of radiofrequency (RF) has been considered a secondary undesirable effect during MRI procedures. In this work, we have measured the power absorbed by distilled water, glycerol and egg-albumin during NMR and non-NMR experiments. The samples are dielectric and examples of different biological materials. The samples were irradiated using the same RF pulse sequence, whilst the magnetic field strength was the variable to be changed in the experiments. The measurements show a smooth increase of the thermal power as the magnetic field grows due to the magnetoresistive effect in the copper antenna, a coil around the probe, which is directly heating the sample. However, in the cases when the magnetic field was the adequate for the NMR to take place, some anomalies in the expected thermal powers were observed: the thermal power was higher in the cases of water and glycerol, and lower in the case of albumin. An ANOVA test demonstrated that the observed differences between the measured power and the expected power are significant.

Objectives. Ménière disease (MD) is an idiopathic disorder that affects hearing and inner ear balance. Intratympanic genta-micin (ITG) is recognized as an effective treatment for uncontrolled MD characterized by persistent vertigo attacksdespite therapy. The video head impulse test (vHIT) and skull vibration-induced nystagmus (SVIN) are validated meth-ods for evaluating vestibular function. A progressive linear relationship has been identified between the slow-phasevelocity (SPV) of SVIN determined using a 100-Hz skull vibrator and the gain difference (healthy ear/affected ear)measured by vHIT. The aim of this study was to ascertain whether the SPV of SVIN was associated with the recoveryof vestibular function following ITG treatment. Consequently, we sought to determine whether SVIN could predictthe onset of new vertigo attacks in patients with MD who were treated with ITG. Methods. A prospective longitudinal case-control study was conducted. Several variables were recorded post-ITG and through-out the follow-up period, followed by statistical analyses. Two groups were compared: patients who experienced ver-tigo attacks 6 months after ITG and those who did not. Results. The sample comprised 88 patients diagnosed with MD who underwent ITG treatment. Of the 18 patients who ex-perienced recurring vertigo attacks, 15 demonstrated gain recovery in the affected ear. However, all 18 patients ex-hibited a decrease in the SPV of SVIN. Conclusion. The SPV of SVIN may be more sensitive than vHIT in identifying the recovery of vestibular function followingITG administration. To our knowledge, this is the first study to illustrate the link between a reduction in SPV and thelikelihood of vertigo episodes in patients with MD who have been treated with ITG.

Objective: The aim of this study was to review the literature about the relevance of the whole body vibration (WBV) in decreasing the number of fractures in osteoporotic women. Methods: Searches were performed by three independent researchers through the PubMed and PEDro databases. Results: Only 0.1% of the publications with “Fracture and osteoporosis” have a relation with WBVexercise. The achievements have revealed a positive effect of this exercise in patients with risk factors for fractures like osteoporosis. Protocols were performed two to three times a week, from 6 up to 18 months, and with 12.6 up to 40 Hz as frequencies. Different tools were used to evaluate the effects of the WBV exercise in conditions that could cause fractures in postmenopausal women. Conclusions: Although the paucity of research regarding direct effects of WBV in decreasing fractures, WBV could be a feasible and effective way to modify well-recognized risk factors for falls and fractures, improvements in some aspects of neuromuscular function and balance. More studies have to be performed establish protocols with well controlled parameters.

Magnetic hyperthermia mediated by superparamagnetic particles is mainly based in sinusoidal waveforms as excitation signals. Temperature changes are conventionally explained by rotation of the particles in the surrounding medium. This is a hypothesis quite questionable since habitual experimental setups only produce changes in the magnetic module, not in the field lines trajectories. Theoretical results were tested by changing the waveform of the exciting signal in order to compare non-sinusoidal signals against sinusoidal signals. Experiments were done at different frequencies: 200 ㎑, 400 ㎑, 600 ㎑, 800 ㎑ and 1 ㎒. Superparamagnetic Iron Oxide samples (SPION), made of magnetite (Fe3O4) and suspended in water (100 ㎎/ml), were used. Magnetic field strength varies from 0.1 ± 0.015 KA/m to 0.6 ± 0.015 KA/m. In this study was observed that the power loss depends on the applied frequency: for 1 to 2.5 RMS current the responses for each signal are part of the higher section of the exponential function, and for 3.5 to 8 RMS current the response is clearly the decrement exponential function’s tale (under 1 × 10³ LER/gr).
