摘要:
There is provided a communication network system which can set communication parameters which enable an operation under a maximum possible communication rate in a situation where a transmission path has cyclic noise/impedance fluctuations, without being influenced by such local noise/impedance fluctuations. A transmission/reception apparatus 100 transmits training packets for checking the state of the power line at two distinct points in time. Each time a training packet is received, a transmission/reception apparatus 101 analyzes SNR at each carrier frequency, and stores an SNR evaluation result. The transmission/reception apparatus 101 compares two SNR evaluation results which are obtained through two instances of a channel estimation algorithm, selects an SNR evaluation result which dictates a faster PHY rate, and transmits it to the transmission/reception apparatus 100. The transmission/reception apparatus 100 changes modulation/demodulation rules based on the received SNR analytical result.

Novel human placenta-derived anticoagulating substances having the following properties:(1) molecular weight of 34,000.+-.2,000 determined by SDA-polyacrylamide gel electrphoresis under reduced state;(2) isoelectric point of 4.7.+-.0.1 determined by isoelectric column electrophoresis using an ampholite;(3) stabilityinactivated by heat treatment at 50.degree. C. to 30 minutes, stable at a pH of 4-10, and stable in plasma at 37.degree. C. for 30 minutes;(4) activitycapable of prolonging a recalcification time, a prothrombin time, and an activated partial thromboplastin time; and(5) the existence of several amino acids including aspartic acid, threonine, serine, and so on; are prepared by homogenizing human placenta, subjecting the resulting homogenate to centrifugal separation, extracting an anticoagulating substance from the residue or from a microsome fraction contained in the supernatant with a surface active agent and/or a chelating agent, and purifying and isolating the substance from the extract.The anticoagulating substances have a high anticoagulating activity and exhibit a higher activity in the state where the tissue thromboplastin activity is exacerbated or in the state of exacerbating the coagulation. Hence, the anticoagulant containing the substance as an effective component has reduced side effects and is thus harmless.
