摘要:
The invention provides a rotor for an electrical motor. The rotor comprises both a squirrel cage and a number of magnets and can be inserted e.g. in a line-start motor. To secure the magnets in cavities in a core of the rotor, an end plate is attached to one axial end face by rivet means, and to simplify manufacturing of the rotor, the rivet means forms part of at least one of the short circuit rings of the squirrel cage.
摘要:
The currently used method for immunological diagnosis of tuberculosis infection, the tuberculin skin test, is problematic for a number of reasons; it has low specificity in BCG vaccinated individuals, a high interobserver variance and requires skill to be read and interpreted. Furthermore it requires an extra visit to the clinic to have the test read. Both people vaccinated with BCG and those exposed to non-tuberculosis mycobacteria give a positive skin test result similar to that seen in a TB infected individual. This also applies for purified protein derivative (PPD) when used in a blood cell based test. The present invention discloses the development of an immunological TB diagnostic tool based on a combination of epitopes from proteins encoded by regions of the M. Tuberculosis (M. tub.) genome, that are not present in the BCG vaccine strain or in the most common non-tuberculosis mycobacteria. Four recently characterized proteins with this diagnostic potential were selected. Peptides from these proteins were tested one by one with peripheral blood mononuclear cells from microscopy or culture confirmed TB patients as well as from healthy BCG vaccinated controls. Some combinations of peptides showed a sensitivity level comparable to the level seen with the two wellknown M. tuberculosisspecific proteins ESAT 6 and CFP 10. An epitope combination with these peptides combined with ESAT 6 and CFP 10 gave a sensitivity of 93%, representing a raise in sensitivity of about 26-33% compared to using ESAT6 or CFP 10 alone. The results from a panel of TB patients, using a collection of the new specific epitopes clearly demonstrates, that addition of other specific epitopes to the already known specific antigens, increases the sensitivity of a diagnostic assay based on cell mediated immune response.

The present invention relates to liposome formulations that are physically stable. In particular the present invention relates to steric stabilization of cationic liposomes by incorporating glycolipids into the liposomes. The stabilized liposomes can be used either as an adjuvant for antigenic components or as a drug delivery system. In particular the invention relates to vaccines with adjuvants in aqueous media for immunization, where the final product is stable.
摘要:
An adjuvant combination and a kit useful for immunization is provided. The kit contains an antigenic substance and an adjuvant combination of dimethyl dioctadecyl ammonium bromide (DDA-Br or DDA-Cl) with a monophosphoryl lipid.
摘要:
A course-holding, high-speed, sea-going vessel having a hull which is intended to hold payloads or passengers and at least one rotatable, preferably electric, rudder propeller (POD) which is arranged gondola-like under the hull of the vessel and has, to supply it with power, at least one motor/generator unit which is arranged in the hull of the vessel, the hull of the vessel having at least in part a bottom which rises somewhat toward the two sides of the hull, and in that the front part of the hull is designed so as to stabilize the course and movement of the vessel and ending under water, in particular in a relatively slender bow with a bulb, and in that a flow-guiding element (skegg) is arranged upstream of each rudder propeller in order both to optimize the handling characteristics and to achieve an optimized flow against the rudder propeller, which has a displacement volume for the water flowing against the respective rudder propeller.
摘要:
A ship includes a ship's hull which is intended for accommodating cargo and/or people, and at least one rotatable steering propeller as a propulsion unit. The rotatable steering propeller is arranged in a connection unit in the form of a box in the stem of the ship's hull. Electrical and mechanical components for supplying power to and controlling the steering propeller and its electric motor are at least partially combined in functional modules which are in the form of a transport container. The container is designed such that it can be functionally tested, can be accepted at its point of manufacture, and can be installed in this form at any desired location in the ship based upon the container base structure.
摘要:
A water purification and/or desalination plant for producing drinking water from a polluted water source or sea water with the aid of sunlight, which plant includes an evaporator (1) having a roof part (2) made of a light-penetrable material, and an underlying basin part (3) containing the water that is to be purified, which basin part (3) includes channels (17) for collecting water vapor that has been condensed on the inside of the roof part (2), and a reservoir (10) for purified water. The plant also includes a device for removing moist air or vapor from the evaporator and a device for condensation of the moist air or vapor outside the evaporator.
摘要:
The invention relates to novel secreted antigens from mycobacteria capable of evoking early (within 4 days) immunological responses from T-helper cells in the form of gamma-interferon release in memory immune animals after rechallenge infection with mycobacteria of the tuberculosis complex. The antigens are present in short term filtrates (ST-CF) from cultured mycobacteria belonging to the tuberculosis complex. One of these antigens, a polypeptide with an apparent molecular weight of 6 kDa, has been identified, and the DNA encoding the polypeptide has been cloned and sequenced. The antigens of the invention are believed useful especially in vaccines, but also in diagnostic compositions, especially for diagnosing infection with virulent mycobacteria. Also disclosed are nucleic acid fragments encoding the antigens as well as methods of immunizing animals/humans and methods of diagnosing tuberculosis.
