Abstract: A propulsion device for a two-wheeled vehicle includes a mechanism for providing traction to a rear wheel for manual advancement of the vehicle and a first epicyclic gear reducer coupled with the mechanism and drivable by a first control device configured for varying the geometric configuration of the first epicyclic gear reducer and thus the gear ratio. A motor for assisting pedalling is interposed between the mechanism for the bottom bracket and the rear wheel and is coupled with a second epicyclic gear reducer, drivable by a second control device configured for varying the geometric configuration of the second epicyclic gear reducer and thus the corresponding gear ratio. The second epicyclic gear reducer is coupled and directly in contact with the rear wheel in order to transmit the movement from the propulsion device thereto.

Abstract: Adhesive hot-melt formulations with a main polymeric component, of at least one isotactic metallocene butene-1 polymer composition, that has a low viscosity, and that has a bimodal composition, directly obtained during polymerization, in two consecutive and separate reaction steps. Moreover, said hot-melts include less than 5% by weight of at least one viscosity modifier that is not solid at room temperature. Such unusually low level of said additives, surprisingly allows to attain substantially improved levels both of high adhesiveness and cohesion. The adhesive hot-melt formulations include less than 5% by weight of a polyethylene wax or of a blend of polyethylene waxes, that characterized by a highly linear/non-branched structure and by an exceptionally low Polydispersity Index. The presence of such peculiar polyethylene waxes, that are partially incompatible with the butene-1 polymer composition, allows to use the disclosed hot-melt formulations even in the presence of fibrous or perforated substrates.

Abstract: The present invention relates to wetness indicator compositions that comprise at least one leuco dye and one color developer in a hot-melt adhesive matrix. Upon contact with water or with water-containing fluids, said wetness indicator compositions are apt to change their color from a colorless state to a colorful state or from a first colored state to a second colored state having a color different from the first one; in particular, from a first colorless, white, or translucent state to a second state having a visible color, or vice versa. The disclosed wetness indicator compositions can be used as wetness/fluid indicators in various applications, e.g. in packaging articles and in absorbent articles; in an absorbent mat or sheet or operatory cloth for medical use; in a wound dressing product; in an absorbent mat or sheet for food products.

The internal tube together with the external tube form an annular space for the circulation of a first fluid. The internal tube includes an internal layer made of PTFE that is intended to contain the second fluid, internal braiding that is intended to lend the internal tube pressure resistance and an external layer that is made of polyamide material which is intended to prevent the passage of the first fluid through the braiding.

Abstract: A device and method for recovering and unloading bar crop ends is suitable for use with a loading apparatus for supplying bars to a machine tool. The devices includes a grasping element suitable for engaging a bar-pushing unit of the loading apparatus and a bar crop-end to be taken and unloaded. A slide element receives and conveys the bar crop ends to a collecting zone. A supporting and transferring unit transfers the grasping element from an upper position, in which it is axially aligned on the advancement trajectory of the bar-pushing unit, to a lower position in which it is near the slide element. The device further includes an ejecting unit that is drivable for penetrating the grasping element in the lower position to eject the crop end and sending the crop end, by the slide element, to the collecting zone. A method is also disclosed for recovering and unloading bar crop ends from a machine tool.

Abstract: The present invention relates to a method for the diagnosis of low overall survival acute promyelocytic leukemia and/or of predicting and/or monitoring the response and/or the efficacy of a therapy for acute promyelocytic leukemia or to identify a subject to be treated with an inhibitor of HAT and/or an inhibitor of EZH2 by determining the acetylation or methylation status of specific relevant regions and relative kit and microarray. The invention also refers to histone acetyl transferase (HAT) inhibitor for use in the treatment of a solid or hematopoietic tumor.

Abstract: Certain example embodiments relate to coated articles with sequentially activated low-E coatings, and/or methods of making the same. In certain example embodiments, one or more infrared reflecting layers is/are activated via a non-equilibrium preconditioning activation that uses photons with specific frequencies/frequency ranges, followed by a more equilibrium thermal activation. The preconditioning activation aids in rearranging the silver atoms to energetically favorable positions, while helping to avoid their unwanted agglomeration. The more equilibrium thermal stage of activation aids in aligning the chemical potentials of the layers of the stack and in further densification of the preconditioned silver layer. Doing so, in turn, helps to reduce the likelihood of stresses building-up in the coating, the formation of point and dimensional defects, other unwanted efficiency-reducing phenomena, and/or the like.
