Abstract: In an embodiment, a method for performing forward error correction (FEC) on protected data packets is disclosed. The method involves creating a FEC table having columns for application data and columns for error-correction data (EC data). Then, a number of protected application data packets are received and placed in the FEC table. If an application data packet is received, then the application data from the packet is placed in the application data column. If an application data packet is not received, generated zeroes are placed in the application data column. Once the application data columns of the FEC table are full, EC data corresponding to the application data is received and placed in the EC data columns of the FEC table. The rows of the FEC table are then fed to the decoder for error correction.

Abstract: A method for producing a single crystal of semiconductor material having material properties of a zone-pulled single crystal includes providing a vessel transmissive to high frequency magnetic fields and having a granulate of a granular semiconductor material disposed therein and a first conductor disposed externally thereto. A high frequency current is supplied to a planar inductor disposed above the vessel, the planar inductor having a turn and a slit as a current supply so as to produce an open melt lake on the granulate by a temperature field at a surface of the granulate produced by thermal power of the planar inductor and a heating action of the first inductor, the melt lake being embedded in unmelted material of the granular semiconductor material and not being in contact with a wall of the vessel. A single crystal is pulled form the melt lake of the semiconductor material upwards.

Abstract: The invention describes a process for preparing acetone starting from acetyl-coenzyme A comprising process steps A. enzymatic conversion of acetyl-CoA into acetoacetyl-CoA B. enzymatic conversion of acetoacetyl-CoA into acetoacetate and CoA and C. decarboxylation of acetoacetate to acetone and CO2, which is characterized in that the coenzyme A is not transferred in process step B to an acceptor molecule. In addition, process step B is surprisingly catalyzed by enzymes of the classes of acyl-CoA thioesterase, acyl-CoA synthetase or acyl-CoA thiokinase. A completely novel metabolic pathway is concerned, because the enzymatic hydrolysis of acetoacetyl-CoA without simultaneous transfer of CoA to a receptor molecule has never previously been described for any microbial enzyme.
