[en] The methods presented in the effort allow to assess heat losses from the fuel composition melted into the lower head based on thermocouple readings positioned near the lower head external wall. This methods enable to restore distribution of the temperature field and heat fluxes along the lower head thickness in different points and at different time points of the experiment, and to evaluate temperature values in the thermo-stressed areas of the lower head where thermocouples failed.

[en] The paper presents regional differences of Lg/Pn ratio in explosion and earthquake records of a Semipalatinsk nuclear explosion recorded by Talgar station and Indian nuclear explosion by Nilor station. In both cases epicentral distances are approximately equal (750 km), but Lg/Pn ratio differs 11-13 times in the nuclear explosion records. Even more distinct differences are observed for earthquakes at the traces crossing Middle Asian and Tibet region. Lg/Pn regional variations are characterized for explosions and earthquakes with regard to specific stations' records and their standard deviations. In the frequency range of 0.3-2 Hz Lg/P value in the explosion records is two times less than in the earthquake records of the same region. This difference and discrimination efficiency increase on high frequencies. Standard deviation does not depend upon a frequency and on average is 0.17 log. units for explosions and 0.30 for earthquakes. Scale of regional and station differences of Lg/P parameter proves the necessity to construct a transportable discrimination criterion for earthquakes on the basis of spatial field of parameter values (database) depending upon epicenter location and chiefly for each single station of the monitoring network. The author first proposed such fields of spectral parameters as long ago as 1975. (author)

[en] With use of experimental data, we have checked efficiency of an optimum filtrating method for monitoring underground nuclear explosions (UNE) by an ionospheric method. In the cases of interest the level of signal at the output of optimum filter was in the range of 0.6 to 0.93, and the level of noises was below 0.5. The probability of accurate detection of UNE was assessed as 100%, when the level of decision threshold was higher than 0.5. (author)

[en] The paper presents seismic recording technique and results of the spectral-temporal analysis of records of industrial explosions conducted in quarries of the Kuzbas region. The spectral-temporal analysis was used at processing explosion seismograms which have been recorded on profiles in the direction of the Bystrovka Test Site. The three-component seismograms and relevant spectral - temporal spectrograms for explosions of Kedrovsky, Vachrushevsky, Taldinsky, Kaltansky and Bachatsky quarries, recorded at distance of 197-334 km are considered.

[en] The article describes the results of the work of study of the influence underground nucleus blasts (UNB) on condition of the day surface of the site Balapan on the territory of Semipalatinsk Test Site using materials of remote space sensing. The estimation of the cosmic spectral analysis information density is given for revealing the post-explosive geo- dynamic processes. (author)

[en] In this work the preliminary assessment of nuclide migration from deep repositories using modelling of the canister defect scenario and CHAN3D, and COMP23 codes is preformed. The results, using CHAN3D code, showed that non-sorbing I-129 is released earliest. Long lived nuclide Cs-135 with a high diffusion coefficient is released later than I-129. Very sorting Pu-239 is released latest and in the smallest concentration. (author)

[en] The purpose of our work was to analyse the effect of conformal (3D) radiotherapy on local prostate cancer control and disease-free survival. We analysed 36 patients aged from 45 to 86 years with T2 prostate tumours. Hormonal therapy was started before conformal radiotherapy using a SATURN-43 linear accelerator and the TARGET planning system. Irradiation was administered with 2 Gy per day to a total dose of 63-74 Gy to the prostate. The early treatment results are available. In 35 (93%) patients a decrease in prostate volume was observed. Also, a significant prostate-specific antigen (PSA) decrease was confirmed. In general, metastases in the study group were determined in 6 pis and local progression in 2 pts. Acute 1-2 grade radiotherapy reactions were observed in 23 pts (58%). The most frequent acute reactions were cystitis, disuria, diarrhoea. Cystitis was reliably more frequent when the total dose was ≥ 66 Gy (p = 0.03). Late (grade 3-4) complications (radiation ulcer of urinary bladder and rectum) were observed in 6 pts (16%). In 3 of 21 patients (14%) late complications were detected when the total dose was ≤65 Gy and in 3 of 12 patients (20%) when the total dose was ≥ 66 Gy. Disease-free survival was 17 months, time to progression was 18.2 ± 1.9 months. Our data confirm a significant decrease of PSA and prostate volume after 3D conformal radiotherapy treatment. The small number of patients and short follow-up period are insufficient to determine the effects of therapy in local prostate tumour. (author)

[en] We investigate the hadron collider phenomenology of the Minimal Supersymmetric Standard Model (MSSM) with explicit CP violation for Higgs bosons that can be observed in Standard Model search channels: W/ZH_i(→bb-bar) at the Tevatron, and gg→H_i(→γγ), tt-barH_i(→bb-bar) and WW→H_i(→τ⁺τ^-) at the LHC. Our numerical analysis is based on a benchmark scenario proposed earlier called CPX, which has been designed to showcase the effects of CP violation in the MSSM, and on several variant benchmarks. In most of the CPX parameter space, these hadron colliders will find one of the neutral MSSM Higgs bosons. However, there are small regions of parameter space in which none of the neutral Higgs bosons can be detected in the standard channels at the Tevatron and the LHC. This occurs because the neutral Higgs boson with the largest coupling to W and Z bosons decays predominantly into either two lighter Higgs bosons or a Higgs boson and a gauge boson, whilst the lighter Higgs boson has only small couplings to the W and Z bosons and the top quark. For other choices of CP-violating parameters, all three neutral Higgs bosons can have significant couplings to W and Z bosons, producing overlapping signatures: these may or may not be distinguishable from backgrounds. The existence of these regions of parameters provides a strong motivation for a detailed experimental simulation of these channels

[en] Seiberg and Witten have discussed a specifically 'stringy' kind of instability which arises in connection with 'large' branes in asymptotically AdS spacetimes. It is easy to see that this instability actually arises in most five-dimensional asymptotically AdS black hole string spacetimes with non-trivial horizon topologies. We point out that this is a more serious problem than it may at first seem, for it cannot be resolved even by taking into account the effect of the branes on the geometry of spacetime. (It is ultimately due to the topology of spacetime, not its geometry.) Next, assuming the validity of some kind of dS/CFT correspondence, we argue that asymptotically de Sitter versions of the Hull-Strominger-Gutperle S-brane spacetimes are also unstable in this 'topological' sense, at least in the case where the R-symmetries are preserved. We conjecture that this is due to the unrestrained creation of 'late' branes, the spacelike analogue of large branes, at very late cosmological times

[en] I study the power-law and de Sitter expansions for the universe during inflation from the STM theory of gravity. In a de Sitter expansion the additional dimension is related to the cosmological constant Λ=3/ψ². I find from experimental data that the mass of the inflaton field is m²=2/(3ψ²). The interesting in this case is that the inflaton field fluctuations are related to the fifth coordinate. In power-law expansion, the fifth coordinate (ψ) appears to be a dimensionless constant. Here, the ψ-value depends on the initial conditions. I find the 5D line element for this inflationary expansion, which is a function of the classical component of the inflaton. But the more important result here obtained is that in both cases there is not dynamical compactification during inflation
