Title: Euthanasia composition of veterinary use, having a high efficiency and fastness in the effect thereof.
Inventor: LOPEZ HECTOR SALVADOR SUMANO
IPC: C12N15/00
Filed: 2008-05-28
Abstract: The present invention relates to a euthanasia composition of veterinary use, Etafin, which is a stable solution based on sodium pentobarbital, sodium phenytoin, cypermethrin and glucose. The present composition is of fast action and has a direct action over the encephalon, producing a sequence of negative events in the vegetative system which guarantee the action of the euthanasia composition without producing moments of anxiety, panic or pain. The function of Eutafin is carried out in the membrane receptors and ionic channels present in the neuronal membrane. The channels and receptors, upon being activated and quickly blocked by the active principles of Eutafin, generate a permanent cell inhibition condition in neurones, which provokes that the whole encephalic parenchyma to remain in a complete condition of chemical inhibition that interrupts the somatic and visceral functions of the animal; effect which promotes an interruption in the neural communication, this latter controlling the vital functions of the cardio-respiratory system, in an irreversible manner causing the euthanasia in a short time and without sudden shocks. This composition is mostly adjusted to the world requirements for the humanitarian animal management.

Title: Apparatus and methods to reduce castouts in a multi-level cache hierarchy.
Inventor: SPEIER THOMAS PHILIP
IPC: G06F12/00
Filed: 2008-01-30
Abstract: Techniques and methods are used to reduce allocations to a higher level cache of cache lines displaced from a lower level cache. When it is determined that displaced lines have already been allocated in a higher level, the allocations of the displaced cache lines are prevented in the next level cache, thus, reducing castouts. To such ends, a line is selected to be displaced in a lower level cache. Information associated with the selected line is identified which indicates that the selected line is present in a higher level cache. An allocation of the selected line in the higher level cache is prevented based on the identified information. Preventing an allocation of the selected line saves power that would be associated with the allocation.
