Effects of Carnoy's solution on blood vessels of the axillary fossa of rats
Carnoy's solution is applied to reduce the recurrence of odontogenic keratocysts and unicystic ameloblastomas. The deleterious action of this fixative on nerves has been studied but no attention has been paid to its effects on nearby vessels. The aim of this study was to investigate the effects of Carnoy's solution on blood vessels. The rat axillary artery and vein were surgically exposed, soaked with Carnoy's solution and kept in place for 2, 5 or 10 min, depending on the treatment group. The 5-min group was followed for 1, 2 and 3 weeks postoperatively. The vessels in the 2-min and 5-min exposure groups showed histological changes to the vessels, represented by focal loss of the endothelium and hyalinization of the wall. These alterations increased in the 10-min group. The vessels in the 3-week observation period revealed signs of recovery. It is concluded that Carnoy's solution can damage blood vessels but the process is reversible for exposure times less than 5 min
Design of Linear Systolic Arrays for Matrix Multiplication
This paper presents architecture for matrix multiplication optimized to be integrated as an accelerator
unit to a host computer. Two linear systolic arrays with unidirectional data flow (ULSA), used as hardware
accelerators, where synthesized in this paper. The solution proposed here is designed to accelerate both
the computation and communication by employing hardware address generator units (AGUs). The proposed design
has been implemented on Xilinx Spartan-2E and Virtex4 FPGAs. In order to evaluate performance of the proposed
solution, we have introduced quantitative and qualitative performance criteria. For the ULSA with n processing
elements (PEs), the speed-up is O(n/2). Average gain factor of hardware AGUs is about 2.7, with hardware
overhead of 0.6% for 32-bit PEs
