Abstract: The U-shaped concrete units and joining corner units for wall construction provide an unmached horizontal and vertical interconnection of grout in a lattice formation between the horizontal reinforcing steel bars, or with the called grid units. For running bond pattern vertical connections using short steel bars with hooks, and for stack bond patten construction allows to use longer vertical bars because of the manuvering possibility with the bottom recessed U-shaped units between the vertical bars.      This method of reinforcing allows to design a wide range of wall strength to resist cracks to appear by light tremor.      The concrete units with grout may also be used for non-reinforced building construction where the lattice formation will provide a unique lateral strength.      The construction whith these concrete units provide an opportunity to reduce the cuts of concrete blocks at construction sites, the cost of those operations, side effects of dust inhalation and accidents.

Abstract: L'invention concerne des procédés et des trousses servant à séparer et à identifier des allèles et, par conséquent, l'haplotype, dans des spécimens d'ADN génomique. Ce procédé consiste généralement à effectuer l'hybridation d'amorces spécifiques pour des sites polymorphes à l'intérieur de ces allèles aux spécimens d'ADN, à prolonger ces amorces par un ou plusieurs acides nucléiques, à séparer les amorces prolongées et à identifier les allèles au moyen de l'amorce prolongée. Ce procédé permet également d'effectuer la ligation de deux amorces, leur séparation et leur utilisation ultérieure afin d'identifier l'allèle ciblé. Ce procédé permet, de plus, d'utiliser une autre amorce en tant que site bloquant pour l'extension de la première amorce, de façon à répliquer et à identifier un segment d'ADN comprenant un site polymorphe. On peut marquer les amorces prolongées ou non, de manière à pouvoir séparer et/ou identifier l'amorce sans difficultés.

Title: Couche d'acquisition repartition d'un article absorbant comportant des volumes vides
Inventor: THOMAS PAUL EUGENE
IPC: B32B27/12
Filed: 2001-09-20
Abstract: L'invention porte sur un article absorbant comprenant une couche supérieure, un noyau de matériau absorbant, et une couche d'acquisition/répartition placée entre la couche supérieure et le noyau. La couche d'acquisition/répartition, qui consiste en un film ajouré en 3 D laissant un important volume vide entre elle et le noyau, notamment un important volume pour les flux latéraux lors d'émissions répétées. De ce fait, la couche supérieure en contact avec l'utilisateur n'a plus à répartir le flux non absorbé par le noyau saturé. Le volume vide constitue une voie permettant au flux non absorbé de circuler au-dessus du noyau depuis les zones saturées du noyau, vers les zones non saturées du noyau pour y être absorbé. Cette migration se fait sans que le fluide soit en contact avec la couche supérieure, ce qui supprime la sensation d'humidité ressentie par le porteur.

Title: Method for short-term and long-term drug dosimetry
Inventor: MORAN S MARK
IPC: A61K9/19
Filed: 2001-10-30
Abstract: Methods for the treatment of interferon-response disorders by administration of an interferon alone or in combination with adjunctive therapy are described. The invention encompasses providing to a patient both a formulation of an interferon that is suitable for short-term administration and a formulation of an interferon associated with a sustained release delivery system that is suitable for long-term administration. A principal advantage of the method is that responsiveness to treatment can be ascertained with short-term dosimetric techniques using one formulation of an interferon, which permits the appropriate selection of a dose that is both effective and safe for long-term administration using the second formulation.

Title: Method and apparatus for allocating a pilot carrier adaptively in an orthogonal frequency division multiple access system
Inventor: JOO PAN-YUH
IPC: H04W24/08
Filed: 2003-03-17
Abstract: A method and apparatus for allocating pilot carriers adaptively in an OFDMA communication system are disclosed. To improve phase error estimation performance and optimize the number of pilot carriers allocated to each sub- channel, an OFDMA transmitter changes the number of pilot carriers for a sub - channel according to the status of the sub-channel. Consequently, less pilot carriers are allocated to a sub-channel in a good state, reducing power consumption and more pilot carriers are allocated to a sub-channel in a bad state, improving channel estimation performance despite increased power consumption.
