A custom-made matrix suitable for receiving a tissue sample is described as well as the use thereof to obtain a multiplex histological preparation. The invention also relates to a multiplex biopsy array comprising tissue and/or cell samples arranged in a matrix material and to a method for the preparation of a multiplex biopsy array. Methods for preparing blocks of matrix material to be used in multiplex biopsy arrays are also described, as well as methods for loading biopsy samples in said blocks, and methods for treating and processing said blocks to form single and multi-specimen preparations such as biopsy arrays. The biopsy arrays made using the block of matrix material can be used to prepare sections and slides for histological procedures, including quantitative analyses and parallel processing.

The invention relates to an anti-diabetic Simulator that incorporates a digital programmer (uControler) from the componence of are signal anti-diabetical generator with precise values minigenerator of low value and small amplitude electromagnetic signals, called anti-diabetes subliminal signals, mounted in a housing together with an electronic device that is designed to start and stop according a schedule the generation of a subliminal signal produced by one software. The generated electromagnetic frequencies constitute external subliminal stimuli needed to energy rebalancing the human body meant for energy simulation of the acupuncture points listed in the diabetes acupuncture treatment protocol recommended in the specialty literature.

The electronic protection device against theft/vandalism allows capturing, processing and treatment of a signal coming from outside which is caused by a person other than the owner and user of such device. Thus, as a result of biodetection of a strange person's specific biometric features, it transmits with some specialized modules (1), (2), through an amplifier (3), an alarm signal toward some audible/optical devices (4), GSM phones (5) and visual monitoring (6). Upon changing the position of the device caused by attempted theft, some GPS capturing and transmission devices 1', 2' send amplified signals to another device 3' which, at its turn, sends a final signal to some alarming GSM phone devices 4' and monitoring visualization 5'.c.

The invention refers to a procedure of 2D and 3D optically assisted fountain pen and aperture pen nanolithography that deposits ink (1) through a cantilever (2) having a perforated tip onto a substrate (4), the cantilever (2) having a channel inside it and being fed with ink (1) by the microfluidic chip (6), the deposition of ink (1) being made under illumination with light from beam (5). The light beam (5) has the role of either photopolymerize ink (1) when ink (1) is a photopolymerizable monomer or to accelerate the evaporation of the solvent that enters into composition of ink (1).

The invention relates to a composition destined to carry out medical elements and devices used for accelerating the osteointegration of a dental implant - such as healing/cicatrizing blunts, temporary prosthetic blunts, dental guards, for obtaining root pivots, immobilization rails and incrustations, crowns and bridges, cushions and head coverings included; at the same time this composition may also be used as an ingredient for obturation materials or for healing a diseased tissue, for example of parodonthosis. All these elements and devices are the subject-matter of the patent entitled "Dental implant, set of medical elements and devices for accelerating the osteointegration thereof and composition for their application", filed in Romania on the date of 25.10.2010 with no. a 2010 01010 by the author of the present invention. The composition claimed by the invention also includes an amount of water structured as a liquid crystal, equivalent as percentage, as against the weight of the mineral employed, to the amount of water of the healthy tissue for which said composition is to be employed.

The invention refers to a modular hydrokinetic assembly which allows the conversion of the kinetic energy of flowing waters into useful mechanical energy for driving some electric generators or water pumping sets, without building dams or culverts. The modular hydrokinetic assembly according to the invention comprises two lower and upper underframes (1 and 2) and a blade assembly (3) formed of two endless chains comprising the plates (20) whereon blades (21) are fastened and actuated by the water of a river, caught from a river by means of a threshold and catching connector and, transmit the mechanical energy by means of a star wheel (23), secured on the axles of electrical generators (4) or water pumping sets (5), the amount of the resulting mechanical energy being dependent mainly on the water flow rate and slope of the channel formed by the lower underframe (1) and, by the radius described by the blades (21) to the axles of the star wheels (23).

The invention refers to a hydrokinetic unit which allows a high level exploitation of the energetic potential of rivers in the plain regions, where the flat relief does not allow to build dams or culverts and which is destined to convert the kinetic energy of flowing waters into useful mechanical energy for producing electric energy or for pumping water by using such modular hydrokinetic assemblies equipped with generators or pumps. The hydrokinetic unit according to the invention comprises a threshold (1) of a constant level provided with flaps (2) and two catching connectors (3) with protection grids (4) and, one or more connections (5) with the flaps which regulate the water flow rates necessary for driving the modular hydrokinetic assemblies (6), connected to the catching connector (3) and, which may be equipped with electric generators or water pumping groups.

The invention refers to a low speed electric generator, The generator according to the invention comprises a housing (1] wherein stator winding cores (2) are mounted, said housing (1] being closed at the ends with shields (3) provided with bearings (4) which allow the rotation of an axle (5) whereon rotor winding cores (6) are mounted, said rotor winding cores (6) being supplied by means of an inductive collector (7) from a source (8) which produces an excitation current with alternative and intermittent polarity; the inductive collector (7) consists of a fixed primary winding (9) comprised in a fixed casing (10) integral with the shield (3], and a mobile secondary winding (11) comprised in the mobile housing (12), integral with the axle (5).
