Patent CA-2517207-C (CA)
Inventor: KRISHNAN RANGANATHAN
IPC: H04L/
Filed: 2004-02-24
Granted: 2013-01-08
Abstract: Pilot and data transmission schemes for multi-antenna communication systems utilizing multi-carrier modulation are provided. Subband multiplexing is used to avoid interference resulting from transmitting multiple signals simultaneously from multiple antennas. M usable subbands are initially arranged to form multiple groups of subbands, with each group including a different subset of the usable subbands (412). Each of T transmit antennas is then assigned one or possibly more subband groups for pilot transmission and typically one subband group for data transmission (414). Pilot and data may then be transmitted from each antenna on the subbands assigned to that antenna for pilot and data transmission (420). For each transmit antenna, the transmit power for each assigned subband may be scaled higher such that all of the total transmit power available for the antenna is used for transmission. Pilot and/or data may be transmitted simultaneously from all T antennas on all usable subbands without causing mutual interference.

Abstract: L'invention concerne des méthodes de traitement et de prévention du cancer du sein, par administration de 4-hydroxy tamoxifène à des patientes. L'invention concerne également des compositions pharmaceutiques de 4-hydroxy tamoxifène adaptées à une administration par voie cutanée. Lorsque le 4-hydroxy tamoxifène est administré par voie cutanée à une patiente, au niveau des seins, le 4-hydoxy tamoxifène se concentre localement et exerce un effet anti-oestrogène. Chez les patientes souffrant de cancer du sein, cet effet réduit la prolifération du tissu tumoral. Chez des patientes exposées au risque de développer un cancer du sein, l'effet anti-oestrogène prévient la formation de tumeurs du sein.

Abstract: A method for recovering inorganic salt during processing of a lignocellulosic feedstock is provided. The method comprises pretreating the lignocellulosic feedstock by adding an acid or a base to the feedstock to produce a pretreated lignocellulosic feedstock. A soluble base or acid is then added to the pretreated lignocellulosic feedstock to adjust the pH and produce a neutralized feedstock. The neutralized feedstock is then hydrolyzed to produce an hydrolyzed feedstock and a sugar stream. Inorganic salt is recovered from a wash stream obtained from the pretreated lignocellulosic feedstock, a stream obtained from the neutralized feedstock, a stream obtained from the sugar stream, or a combination of these streams. The inorganic salt may be concentrated, clarified, recovered and purified by crystallization, electrodialysis, drying, or agglomeration and granulation, and then used as desired, for example, as a fertilizer.
