... Single-crystalline eutectic oxide fibres are needed to reinforce metal, intermetallic and ceramic matrices to obtain high temperature composites. ... The method of internal crystallization was developed in Laboratory of Reinforced Systems of Solid State Physics Institute initially to produce oxide-matrix/molybdenum-matrix composites, which were considered mainly as model ones. ... Figure 1 . ... The oxide/molybdenum block is then moved to a cold zone of the furnace to crystallize the fibres. ...

Most radio and modem clocks used for a primary (stratum-1) NTP server utilize serial ports operating at speeds of 9600 baud or greater. ... In order to reduce these errors, a set of special line disciplines and stream modules can be configured in the Unix kernel. ... Note that not all Unix kernels support line disciplines and of those that do, not all support System V streams. ... There are two line disciplines and a special streams module included in the distribution. ...

... 1997: . The character of internal motions of gas in 7200 HI clouds in the outer region of our Galaxy was investigated according to the data of the HI survey with the RATAN-600. It turned out that the effect of turbulence, as the main mechanism of gas motion is not essential, while it was discovered that 36% of the clouds are rotating. ... Periodic variations of optical emission of the gamma, X-ray and radio pulsar GEMINGA were for the first time discovered from the observations with the BTA. ...
