A process for separating, in the liquid phase, a reaction mixture which comprises a first chlorinated sucrose and at least one additional component selected from the group consisting of at least one other chlorinated sucrose different from said first chlorinated sucrose, salt and solvent, by injecting said reaction mixture onto a fixed bed of solid adsorbent and treating with a desorbent such that...

The present invention is a nanocomposite which is a dispersion of nanofiller particles derived from layered metal oxides or metal oxide salts. The nanocomposite is advantageously prepared by first swelling an untreated clay in water, then removing the water to form an organophilic clay that is dispersible in non-polar organic solvents. The organophilic clay can then be treated with an alkyl alumin...

Controlled release of hydrophobic bioactive substances in vivo over an extended time period and without "bursts" of drug release achieved using a liquid polymeric composition including a polymer such as poly(lactide-co-glycolide) copolymer in a mixture of hydrophilic and lipophilic solvents.

The present invention relates to a method for producing microstructures, nanostructures, or objects. This method involves providing a rod-coil block copolymer including a rigid-rod block and a flexible-coil block, mixing the rod-coil block copolymer and a selective solvent for one of the blocks which solubilizes that block, and permitting the rod-coil block copolymer to self-assemble into organize...

The present invention relates to a carrying strap for the transportation of boxes, trays or similar containers in horizontal position, basically made up of a strap (1) of polyethylene or strong paper and provided with a top handle; it is being provided that, when expanded, the lower end (3) of the strap (1) represents the surface on which the object (C) to be transported is placed in horizontal po...

Disclosed are pharmaceutical compositions for oral administration which contain inclusion complexes and are characterised by rapid release of the active ingredient and the fact that they require no use of liquids for administration, being the saliva present in the oral cavity adequate for dissolution of the active ingredient. Said formulations are particularly useful in increasing the bioavailabil...

Methods for fabricating nano-structured surfaces having geometries in which the passage of elementary particles through a potential barrier is enhanced are described. The methods use combinations of electron beam lithography, lift-off, and rolling, imprinting or stamping processes.

Limited rotation, micro-lens scanning of DNA arrays, microscope slides, biological materials, etc., is performed by arcuate and translational motion. A scanning system includes an objective lens located on a low moment of inertia oscillating arm, which provides optical coupling to a light source or a light detector arranged for transmission, reflection, or fluorescence microscopy.

Disclosed are pharmaceutical compositions containing inclusion complexes of melatonin in a polymeric material, in particular in beta -cyclodextrine. These compositions are particularly useful for dissolving melatonin in aqueous solvents and increasing melatonin bioavailability.

Pregnancy-associated glycoproteins (PAGs) are structurally related to the pepsins, thought to be restricted to the hoofed (ungulate) mammals and characterized by being expressed specifically in the outer epithelial cell layer (chorion/trophectoderm) of the placenta. By cloning expressed genes from ovine and bovine placental cDNA libraries, the inventors estimate that cattle, sheep, and most probab...

The present invention provides compositions, useful for making lyocell fibers, having a high hemicellulose content, a low lignin content and including cellulose that has a low average degree of polymerisation (D.P.). Further, the present invention provides processes for making compositions, useful for making lyocell fibers, having a high hemicellulose content, a low lignin content and including ce...

The invention relates to a resilient foot insert for an artificial foot, having at least one spring element that determines the spring rigidity of the artificial foot, and an adapting device for changing the spring rigidity of the spring element. In order to improve and simplify the adaptation of the foot insert to the respective use conditions, the invention provides that the adapting device be a...

The invention relates to a method and a device for treating wafers presenting components during thinning of the wafer, separation of the components and the intermediate production steps. The front of the wafer having the components is coated with a layer which remains on the front side of the wafer after thinning, the other production steps and separation. The advantage of the invention is that it...

A method for standby switching in optical transmission devices is provided, wherein, in addition to a working signal and a protection signal, respective control signals with information concerning the allocation state are transmitted and evaluated at the receiving end. The control signals are transmitted via a monitoring channel even when the useful signal is switched off.

It is an obtain a subpolygon having a smooth three-dimensional shape from a polygon A Bezier curve, as interpolated line B12 which interpolates between vertices P1 and P2 of quadrilateral polygon P1P2P4P3 is determined using normal vectors n1 and n2, and an interpolated line B34 interpolating between vertices P3 and P4 is determined using normal vectors n3 and n4. Then, interpolated points P12 and...

In a hand-held display device for use with an electronic device to display a complete or a determined part of a screen image, there are included control circuits, a display screen and control buttons connected to said control circuits. Further, a gyroscope is incorporated in said display device and connected to said control circuits, whereby said display device is responsive to movements in the sp...
