Abstract: A rolling device adapted to roll on a ground surface, including at least one motorized wheel including a circular stator and a circulator rotor. The stator may include a circular slot and a plurality of electromagnetic coils located in the circular slot so that at least two electromagnetic coils are arranged facing one another. The circular motor may include a circular strip having side walls and a free end edge connecting the side walls, as well as a contact surface with the ground, the circular strip including magnetic elements arranged on the side walls thereof. The circular rotor and the circulator stator may be assembled by means of assembly means provided on the circular stator.

Abstract: A compound, or a pharmaceutically acceptable salt or isomer thereof, of Formula I: wherein R is hydrogen, alkyl, substituted alkyl, alkenyl, or substituted alkenyl; R1 is hydrogen, alkoxy, or substituted alkoxy; R2 is hydrogen, alkyl, or substituted alkyl; and R3 is hydrogen, alkyl, or substituted alkyl.

Abstract: Robotic systems include an articulated arm having a deformable assembly consisting of having a plurality of bars connected by parallel pivot axes to form at least one deformable structure, the distal end of the deformable assembly supporting a mechanical interface, the system further including two actuators which rotate two of the bars, and a third actuator controlling the translational movement of the deformable assembly in a direction parallel to the pivot axes.

Abstract: A compound, or a pharmaceutically acceptable salt or isomer thereof, of Formula I: wherein R is hydrogen, alkyl, substituted alkyl, alkenyl, or substituted alkenyl; R1 is hydrogen, alkoxy, or substituted alkoxy; R2 is hydrogen, alkyl, or substituted alkyl; and R3 is hydrogen, alkyl, or substituted alkyl.

Abstract: The present invention relates to a non-biological skin model comprising a polymeric material reproducing skin surface topography that is coated with a lipid composition, wherein the polymeric material is a material having a surface free energy (?) of between 14 and 60 mJ/m2, wherein the lipid composition comprises from 14% to 60% of triglycerides, from 2% to 40% of free fatty acids, from 4% to 30% of wax esters, from 3% to 20% of squalene, and from 1% to 10% of cholesterol, and wherein the surface concentration of the lipid composition on the polymeric material is between 500 ?g/cm2 and 2500 ?g/cm2. The present invention also relates to a method for preparing said non-biological skin model and to its use for evaluating cosmetic products performance or for evaluating the effect of pollution on skin surface properties.
