“…It must also be kept in mind that the number of vehicles with high center of gravity, such as vans, SUV, or off-road vehicles is particularly sensitive to speed bumps. It is therefore of great interest to characterize different types of speed bumps at different speeds and with different types of vehicles, analyzing its influence on the stability, comfort, and safety [14, 15].…”

During a journey, motor vehicles are subjected to different types of irregularities in the pavement. Some of these irregularities are introduced for a specific purpose over a stretch of road to slow down the vehicle at certain road points. However, the influence of installed speed bumps reveals certain additional effects which must be deeply analyzed to ensure vehicle and pedestrian safety. In some cases, it has been found that even when driving over transverse bands at a speed below the legal limit, the vehicle is damaged or tires lose grip with the pavement, precluding any kind of braking or turning maneuvers. Such phenomena indicate that either this element is not properly sized or the location is not appropriate, becoming counterproductive for traffic safety. In order to analyze the influence of these irregularities on the different components of the vehicle and its occupants, a simulation program with MatlabTM has been developed. The validated developed tool takes into account several aspects of the vehicle dynamics, bump geometry, and vehicle speed. The proposed tool provides the best possible information to establish a set of guidelines for the proper design and installation of speed bumps in different roads.

“…According to Martínez-Ortí et al (2007), peninsular species cannot be distinguished by the analysis of its genitalia due to the anatomical simplicity. In spite of this, in other European species, this does Despite this panorama, Aparicio (2006) cited a diversity of 47 species and 18 families of molluscs within Madrid, undoubtedly surpassed by many other regions of Spain. So, studies that reveal the presence of new species in Madrid, will be interesting for malacology in general, at the time that increases the diversity of this region.…”

Taxonomic redefining of Pyramidula jaenensis (Clessin, 1882) (Gastropoda: Pyramidulidae) based on an integrative taxonomy approach

The genus Pyramidula presents a Palearctic geographical distribution, being described in Spain four species not distinguishable from an anatomical point of view. In the present study, we compare our samples along with the previously recognized species P. rupestris, P. saxatilis, P. pusilla, P. cephalonica; P. jaenensis, and P. chorismenostoma by means of molecular studies. Also, we compared P. jaenensis from the studied locality with P. rupestris according to the shell shape by means of geometric morphometric methods. The analysis of the Thin-Plate Spline graph showed that P. jaenensis presented an expansion on the growth to the first whorls and the apex, whereas the height of the body whorl was moderately contracted, while in P. rupestris the opposite was found. We found significant differences between both species based on shell shape. We also provide new information about morphological features that could be used in future studies of this genus attempting to stablish a baseline to test whether the Spanish species are cryptic species or not. The present study also extends the distribution of Pyramidula to Madrid, Spain, establishing for the first time the presence of P.
