Abstract: A process is described for the preparation of drospirenone, a synthetic steroid with progestogenic, antimineralocorticoid and antiandrogenic activity, useful for preparing pharmaceutical compositions with contraceptive action by the oxidation of 17?-(3-hydroxypropyl)-6?,7?,15?, 16?-dimethylene-5?-androstane-3?,5,17?-triol.
Abstract: The use of dimiracetam in the treatment of chronic pain is disclosed. At doses higher than those previously disclosed in relation with its cognition enhancing activity (i.e. amelioration of learning and memory), dimiracetam was able to completely revert hyperalgesia or allodynia associated with several animal models of chronic pain. Dimiracetam showed high activity in iatrogenic neuropathies associated with antiviral and chemotherapeutic drug treatments and in painful conditions caused by osteoarthritis. In addition, dimiracetam was devoid of toxicity even at doses 10-fold higher than the highest therapeutic dose. The possibility of treating such debilitating pathologies with a highly effective and essentially non-toxic compound is therefore disclosed.

Abstract: A multicomponent polyurethane/vinyl ester hybrid foam system for forming a gradient foam with soft and rigid foam regions, with a polyol component (A), a polyisocyanate component (B), and a component (C), which contains a catalyst for the polymerization of the vinyl monomer, with the polyol component (A) containing, as vinyl monomer, a mixture of vinyl esters of at least one polymerizable hydroxyvinyl ester and at least one branched, at least trifunctional, polymerizable vinyl ester, and the polyisocyanate component (B) containing a thermally activatable free radical-forming agent as catalyst for the polymerization of the vinyl monomers, with the proviso that the proportion by weight of the vinyl ester mixture is greater than the proportion by weight of the at least one polyol as well as the proportion by weight of the at least one polyisocyanate.
Abstract: A photocatalytic method for the hydroxylation of alkanes involving the use of a Cytochrome P450 class of enzyme as a catalyst which is activated by exposure to a pulsed blue light emitted from a light emitting diode (LED) at 450 nm±25 nm.
Abstract: An apparatus for accurately determining if a substrate is properly retained by a substrate-retaining mechanism. The apparatus includes a substrate-retaining mechanism to retain a wafer, a treatment liquid supply mechanism to supply a treatment liquid to the wafer, and a rotatable cup adapted to rotate as an integral unit with the substrate-retaining mechanism while covering the outer peripheral portion of the wafer. The substrate-retaining mechanism has a retaining member with two ends. If the first end retains a wafer, the second end is in an upper position. If the first end retains no wafer, the second end is in a lower position. A touch sensor is arranged below the second end of the retaining member so that, when the second end is in the lower position, the second end makes contact with the touch sensor.
Abstract: Apparatus and method for monitoring a body portion of a user during the use of a gymnastic machine provided with a video monitoring apparatus; this method comprising a phase of defining the body portion to be monitored, followed by a phase of visually and continuously monitoring this body portion through the video monitoring apparatus; this last phase comprising a sub-phase of synchronizing the trend over time of the value of at least one operating parameter of the video monitoring apparatus with a motion of the body portion described on the basis of given kinematic information acquired by a control unit of the gymnastic machine.
Abstract: A plasticized polymer of PLGA employing ethanol as the plasticizing agent prepared at a temperature higher than the Tg and lower than the boiling point of ethanol can be used in subcutaneous implants containing active ingredients therein.
Abstract: A text-independent speaker verification system utilizes mel frequency cepstral coefficients analysis in the feature extraction blocks, template modeling with vector quantization in the pattern matching blocks, an adaptive threshold and an adaptive decision verdict and is implemented in a stand-alone device using less powerful microprocessors and smaller data storage devices than used by comparable systems of the prior art.
Abstract: A bearing module for supporting a rapidly rotatable shaft of a vacuum pump includes a rolling bearing for supporting rotatably the shaft, a reservoir for a lubricant having an element forming a sliding contact with a delivery structure supported on the shaft for delivery of the lubricant in the rolling bearing under action of centrifugal forces generated during rotation of the shaft, and a radial delivery element provided on a side of the rolling bearing opposite a side of the bearing at which the delivery structure is located, for returning the lubricant to the reservoir.
Abstract: A power tool stand includes a guide carriage (4), and a tool coupling (1) for a portable power tool (3) and including a carriage coupling member (1a) provided on the guide carriage (4), having a clamping surface (5a), two hooks (7a, 7b) spaced from each other along the clamping surface (5a) with at least the first hook (7a) being displaceable along the clamping surface (1a), and connectable with a tool coupling member (1b) for the power tool (3) and having a clamping surface (5b the tool coupling member (1b) having two free-lying, arranged at least partially circumferentially, bolts (6) which can be hanged behind the two associated hooks (7a, 7b) of the carriage coupling member (1a).

Abstract: The method and the apparatus object of present invention refers to a system and A method that create, save and format text documents using a device with gaze control and a system of quick positioning of the cursor. The present invention provides a faster interaction and requires a minimum effort with respect to the state of the art interfaces.
Abstract: The systems and processes of the present invention includes ESP variable speed drive controllers that function in conjunction with a safety logic solver, pressure sensors, and an emergency isolation valve to perform a functional test of the complete wellhead trunkline protection system without interruption of production.
Abstract: A replaceable chuck for a percussion hand-held power tool (3) for applying axial blows to a working tool receivable in the chuck, includes a release sleeve (4) axially displaceable relative to the base body (6) against a spring-biasing force and including an inwardly located locking element (11) for formlockingly securing the chuck on a power tool spindle (15) with locking elements (12) extending through respective openings (13) formed in a base body (6) and engageable in associated recesses (14) of the power tool spindle (15), and a formlocking displacement guide (5) that provides for displacement of the release sleeve (4) relative to the base body (6) and includes, along its axial extension, a tangential section.
Abstract: Disclosed is a liquid treatment apparatus capable of effectively exhausting processing liquid atmosphere around a target object.

A discharge mechanism discharges processing liquid atmosphere guided by the rotation cup and the rotation exhaust cup.
Abstract: Equipment for use in changing a catheter, preferably of the type used for drainage of the urinary tract. The urinary catheter is used as an aid in emptying the urinary bladder in conditions where this cannot be done in the normal manner. The equipment of the present invention includes a sleeve mounting unit which is mounted to an indwelling catheter, and which has a branch member formed in one piece therewith and extending at an acute angle therefrom, for reception of an elongated sleeve having a longitudinal slit. The sleeve is positioned on the branch member and then progressively advanced onto the catheter, causing the slit to become enlarged as the sleeve surrounds the upstream portion of the catheter in a yielding manner. The catheter may then be quickly removed through the sleeve and a new catheter inserted in its place.
