A method of producing a mainly carbonate bonded article includes a step of providing an alkaline granular material having one or more alkaline earth metal silicate phases. The method includes a step of compacting the granular material to obtain a compact of the granular material. The porosity of the compact is smaller than or equal to 37% by volume. The intrinsic permeability of the compact is at least 1·10−12 cm2. The method also includes a reacting step arranged to form at least 5% by weight of carbonates (CO32−), by reacting the granular material with carbon dioxide in the presence of water, thus transforming the compact into the article. In the reacting step, the compact, being unsaturated with moisture at the beginning of the reacting step, is brought in an atmosphere having carbon dioxide. The atmosphere is at a temperature of at least 70° C. and at a pressure of at least 0.5 MPa. The pressure is also higher than the saturated vapor pressure of water at the temperature. As a result, at least a portion of the carbonates are formed by reaction of the one or more alkaline earth metal silicate phases. Articles are also obtained by the method.

The present invention relates to a method and a system for on-site and full-scale testing of wind turbine plants. In particular, the present invention relates to a method and a system applying resonance circuits tuned with the fundamental frequency, or harmonics thereof, of a power supply grid connected to a wind turbine plant to be tested. The wind turbine plant to be tested may remain connected to the power supply grid during on-site and full-scale testing.

The Invention is a tray for serving a beverage in a nightclub or tavern. A tray body defines a reservoir adapted to contain a beverage. A reservoir aperture communicates through the tray body and is controlled by a valve. A dispensing opening is defined by the bottom side of the tray body and aligns the drinking vessel with the reservoir aperture. The valve is actuated when a drinking vessel is placed in engagement with the dispensing opening. A plurality of drinking vessel receptacles located on the top side of the tray are adapted to support drinking vessels.

An electrical feedback detection system for detecting electrical contact between a multi-point probe and an electrically conducting material test sample surface. The electrical feedback detection system comprises an electrical detector unit connected to a multitude of electrodes in the multi-point probe, and optionally directly to the test sample surface. The detector unit provides an electrical signal to a multi-point testing apparatus, which can be used to determine if the multi-point probe is in electrical contact with the test sample surface. The detector unit comprises an electrical generator means for generating an electrical signal that is driven through a first multitude of electrodes of the multi-point probe, and a second multitude of switched impedance detection elements. The electrical potential across the impedance detection elements determines the electrical contact to the test sample surface.

The Invention is an apparatus which may be a drinking vessel to contain dry ice submerged within a beverage to create a visual effect. A partition has a first side and a second side and is adapted to contain dry ice on the first side. The partition is adapted to allow the beverage to flow from the second side of said partition to said first side of said partition when said partition is immersed in the beverage, exposing the beverage to the dry ice, creating a visual effect and chilling the beverage.
摘要:
Novel peptide nucleic acids and novel linked peptide nucleic acids, form triple stranded structures with nucleic acids. The peptide nucleic acids include ligands such as naturally occurring nucleobases attached to a peptide backbone through a suitable linker. Other nucleobases including C-pyrimidines and iso-pyrimidines can be used as the ligands in Hoogsteen strands to increase binding affinity. Two peptide nucleic acid strands are joined together with a linker to form a bis-peptide nucleic acid. The individual strands of the peptide nucleic acids in the bis compounds can be orientated either parallel or antiparallel to each other.
