[en] Oxides and kouprates are synthesized on the basis of extra conducting ZrV₂ and Nb₃Sn. Their temperature dependences of conductivity, dielectric permeability and tangent of the corner of dielectric losses are taken. (authors)

[en] The results of the development of the computerized nuclear materials accounting system at the Joint Institute for Nuclear Research (JINR) are submitted. This work was carried out under Russian-American Nuclear Materials Protection, Control and Accounting (MPCandA) Program. The System was implemented at the Institute, it was attested to work with sensitive information. The computerized information nuclear materials accounting and control system, named MTIS (Materials Tracking Information System), is intended for the automated accounting of the nuclear materials used in JINR, tracking their moving, changes of their inventory amounts, preparation of the required documentation, and also for information support of the measures spent in the JINR on MPCandA program. MTIS can prepare reports for federal level and can also generate data to be reported for internal purposes. MTIS includes as one of the subsystems a program module to prepare reporting information to the Federal Information System (FIS). The system MTIS provides control of access to the database (DB), protection of the information against the non-authorized access, division of the data into the sensitive and non-sensitive data.

[en] The programs complex for control over energetical delivery system for the elaborate physical experiments is described. Gauge system was implemented on the VME crate with the VM-40 (MC68040) processor. The programs, collecting the data about the system state and primary processing of parameters, were created in MicroWare C language and run in OS-9 system environment in VME crate. The programmes executing the displaying and saving the energetical delivery system state were created and run in LabView environment in Microsoft Windows NT system shell. TCP/IP protocol was used for communication between OS-9 and Lab View. (author)

[en] The description of the communication subsystem between JINR and Federal information system which is included as part in the nuclear materials accounting and control computerized system of Institute is given. The components of the interface between nuclear facilities and Federal Information Centre, organization of interaction between them, formats of exchange files, program and means of a subsystem are considered.

[en] Thermogravimetric method was used to examine the process of synthesis of high temperature ceramic Y-Ba₂-Cu₃-O_7-δ in range from the room temperature up to 900 centigrade degrees in inert and air atmospheres. In process of both heating and cooling a change of the examined material mass was determined

[en] The results of investigation into the electrical properties of Svetlanit type pyrolytic boron nitride and cubic boron nitride are presented. The retention of electrical resistance anisotropy, of dielectrical constant and of dielectrical loss tangent is determined for pyrolytic boron nitride. Activation energies are determined. 9 refs., 3 figs., 1 tab

[en] The substantiation of choice of the hardware and software for integration in program-technical complex is given. The complex is intended for automation of the physical experiments connected with chain nuclear reaction investigations. The subsystem for energy supplying control of experiment is considered in detail. For building the subsystem the 'client-server' architecture is used. The subsystem includes the work station and VMEbus measuring modules in the net. The description of the programs and result formats are given. 5 refs., 6 figs
