Abstract: The present invention provides a new strategies for the synthesis of compounds of the rocaglamide family and related natural products. The synthetic approach generally involves photochemical generation of an oxidopyrylium species from a 3-hydroxychromone derivative followed by an enantioselective 1,3-dipolar cycloaddition of the oxidopyrylium species to a dipolarophile in the presence of a TADDOL derivative. This approach can be used for the formation of adducts containing an aglain core structure. Methods of the conversion of aglain core structures to aglain, rocaglamide and forbaglin ring systems are also provided. The present invention also relates to the use of rocaglamide/aglain/forbaglin derivatives for the manufacture of medicaments for use in the treatment of cancer or cancerous conditions, disorders associated with cellular hyperproliferation, or NF-.kappa.B-dependent conditions.

Abstract: A cryoprobe for surgical and other treatments. The cryoprobe comprises an expandable section that performs displacement of a distal cryotip forwards when there is elevation of the operation pressure in the interior of the cryoprobe. Needle-wise metal elements are installed on the external side of the cryotip. These needle-wise elements are deflecting outwards by a deflecting member fastened on the distal edge of an external shaft of the cryoprobe. This allows a significant enlargement of the frozen volume of the treated tissue with the same operation temperature and the outer diameter of the cryoprobe. In another embodiment, the needle elements are formed in a displaceable metal sheath and a distal section of a cryotip and/or special protrusions on this distal section act as the deflecting member.

Filed: 2007-09-05
Abstract: The invention relates to a method for both dewatering and drying solid-liquid mixtures and to a device formed as a filter press dryer for application of the method. The filter press dryer is fitted with a defined number of metal heating chamber filter plates (1) and/or membrane heating chamber filter plates (2) arranged next to one another and parallel to one another. The method comprises the following simplified steps: a) supplying the suspension, b) draining off the filtrate while at the same time holding back the solid fractions as a filter cake, c) heating up the filter cake, d) squeezing the filter cake formed during dewatering, e) drying the filter cake by evacuating the vapour space (4) and the pore space in the filter cake, f) filling the vapour space (4) and the pore space in the filter cake with air or inert gas of up to 1 bar positive pressure, whereby a break in the drying is initiated and the filter cake heats up again, g) repetition of steps e) and f) until the intended degree of drying is reached, h) switching off the heating circuit and ending the membrane pressing and g) removal of the dried filter cake. A surprising increase in the drying rate is achieved in this way in comparison with the solutions known from the prior art.

Abstract: La présente invention porte sur un système et une méthode permettant la gestion dynamique de l'énergie d'un dispositif mobile. Le dispositif mobile comporte une pluralité de charges et un chargeur d'alimentation raccordé électriquement à un rail d'alimentation en tension. La méthode comprend la surveillance de la pluralité des charges pour déterminer le moment où au moins une des charges deviendra active ou inactive, déterminant une tension d'entrée minimale requise à fournir par le convertisseur de tension en fonction des charges actives et la au moins une charge qui deviendra active ou inactive et le fonctionnement du dispositif, et le réglage d'une tension d'entrée à l'aide d'un convertisseur de tension pour fournir la tension minimale d'entrée requise sur le rail d'alimentation en tension avant que la au moins une charge devienne active ou après que la au moins une charge devienne inactive. La méthode assure également la surveillance de la tension d'entrée et détermine si la tension d'entrée est inférieure à un seuil prédéterminé. Lorsque la tension d'entrée passe sous le niveau du premier seuil, la méthode permet de réduire la tension de sortie fournie par le convertisseur de tension, ce qui permet de réduire le taux de recharge du chargeur de batterie.

Abstract: A C to T DNA variation at position 3365 in exon 5 of the human Asthma Associated Factor 1(AAF1) produces the predicted amino acid substitution of a methionine for a threonine at codon 117 of AAF1. When this substitution occurs in both alleles in one individual, it is associated with less evidence of atopic allergy including asthma, fewer abnormal skin test responses, and a lower serum total IgE. Thus, applicant has identified the existence of a non-asthmatic, non-atopic phenotype characterized by methionine at codon 117 when it occurs in both AAF1 gene products in one individual.

Title: Fuses
Inventor: CRANE ALLAN DAVID
IPC: H01H85/00
Filed: 2009-06-11
Abstract: The present invention relates to a fuse assembly for rapid interruption of a prospective fault current. The fuse assembly includes a plurality of splitter plates (8).  A plurality of foil elements (6) extend between a pair of terminals (2, 4) and are physically supported by the splitter plates (8). A pair of parallel busbars (12, 14) are in series with the foil elements (6) and generate a magnetic field (B) that is substantially perpendicular to the current flowing in the foil elements (6). In the presence of a prospective fault current, the foil elements (6) will melt and at arcing inception an electromagnetic force developed as a result of interaction between the magnetic field (B) and the arc current will push the molten foil elements (6) into the splitter plates (8). This increases the arc length and hence the arc voltage.   At least the foil elements (6) and the splitter plates (8) are preferably located in flowing liquid dielectric such as MIDEL 7131, for example. The liquid dielectric flow may help to push the molten foil elements (6) into the splitter plates (8) and removes debris away from the arc site.

Abstract: A method to clean a wellbore and the near wellbore area adjacent to the wellbore of a hydrocarbon bearing and/or coal bed methane formation adjacent to the production zone of the wellbore is provided. Specifically, a method for removing liquids such as water and/or oil from the near wellbore formation is provided. Furthermore, A method to clean a casing inserted into a wellbore is also disclosed. A method for cleaning a wellbore of fracturing fluid, with or without proppant is also disclosed. Each of the methods includes the steps of injecting either liquid carbon dioxide or a treatment medium comprising liquid carbon dioxide into a wellbore through tubing such that the location at which the treatment medium is administered may be controlled. In some embodiments, pressure within the wellbore is regulated in order to either maintain the treatment medium in the liquid state, or allow at least a portion of the treatment medium to vaporize upon introduction into the wellbore. Once the treatment medium has at least partially vaporized it will loosen and/or entrain undesirable materials from within the wellbore or casing, and may also act to mobilize any water and/or oil present by causing the water to effervesce and/or by dissolving any oil. These processes may act to defeat capillary pressure mobilizing the water and/or oil such that it may be blown or pumped to the surface or, if the present invention is practiced in a coal bed methane formation, may be driven into the coal bed methane formation such that it may no longer impose a barrier to methane production. In certain embodiments, the gaseous portion of the treatment medium is allowed to escape through the wellhead, carrying with it the undesirable materials.
