The invention relates to the identification of new mutations or combinations thereof (mutation profiles) in the inverse transcriptase gene and/or in the surface antigen of hepatitis B virus (HBV) potentially related with the genotypic resistance in vitro and in vivo to the therapy with antiviral drugs. In particular, the invention relates to methods for the genotypization of a viral population and...

The method allows the control in steady state, without a position sensor, of a two-phase d.c. brushless motor (BM) comprising a permanent magnet rotor (R) and two phase windings (W1, W2) connected in series to respective electronic switches (M1, M2) between the two poles of a d.c. voltage supply source (V CC ). The switches (M1, M2) are driven in such a way that they are rendered alternately condu...

Described herein is a device with vertical transition (1) having a plurality of layers set on top of one another, which define a first transmission line (2) and a second transmission line (3); the first transmission line (2) has a first conductive path (5) and the second transmission line (3) has a second conductive path (10); an electrical connection structure (20, 21) extends vertically through ...

A milling machine (1) for machining edges (16, 17), in particular edges of a conductive bar for an alternator stator, has a structure (18), and a number of bearings (7, 8) defining a guide seat (13) extending along a longitudinal plane (14) and engaged by the bar (3); at least one of the bearings (7) is fitted to a slide (76) that slides, with respect to the structure (18), along an adjustment axi...

A waterproof membrane (1), particularly for insulating buildings subjected to hydrostatic pressure, comprising a first layer (2) of water-expandable waterproof material adapted to cover the outer surface of at least one wall (3) to be insulated of a building and a second layer (4) of fibrous material that covers the first layer (2) on the opposite side with respect to the wall (3) to be insulated....

The finding concerns a machine for roller finishing natural skins, leather and the like, also called "coating machine" or "spreading machine", in which the skins (P) are conveyed by a lower roller or by a belt (5) and where an upper spreading roller, made up of a gravure cylinder (1), pressing down on the surface (S2) of the skin, countered by the underlying cylinder or belt, deposits a film of li...

Flexible hose, particularly a shower or gardening hose, comprising, as viewed from the inside: - at least one inner supporting layer (4) susceptible of contacting the liquid to be conveyed; - at least one fibrous reinforcement layer (5) of braided or tricot knitted type; - at least one outer layer (2); wherein said at least one inner supporting layer (4) or said at least one outer layer (2) is...

The invention regards a cutting and edge-coating removal head to be mounted on cutting benches of sheets of glass (V), coated by the film (S). Such a head (1) is characterised in that the cutting tool (20) is positioned inside the edge-coating removal tool (10), consisting, for example, of a diamond-tipped disc, a cup grinder or spark grinder, a pad, a blade, or a brush with steel bristles.

A backlighted push button for game machine comprises a body (2) for hooking to the game machine and for supporting at its upper end of a covering body (4). Inside the body (2) and the covering body (4) is housed a sliding element (3) supporting a cap (5) illuminable by the passage of a luminous bean (R) from the inside towards the outside of the push button (1) of a luminous source inside this la...
