Diffraction 2000: New Scaling Laws in Shadow Dynamics
New scaling structure for the shadow corrections in elastic scattering from
deuteron at high energies has been presented and discussed. It is shown that
this structure corresponds to the experimental data on
proton(antiproton)-deuteron total cross sections. The effect of weakening for
the inelastic screening at superhigh energies has been theoretically predicted.Comment: LaTex2e, espcrc2.sty, 2 figures, Contribution to the Workshop

Experimental study of self-induced transparency mode-locking in Ti:sapphire laser
In this paper, passive mode-locking in Ti:sapphire laser with a coherent absorber cells with rubidium vapor placed in the cavity is demonstrated experimentally. For the best of our knowledge these experiments are the first time experimental demonstration of passive mode-locking based on self-induced transparency regime in the coherent absorber. Up to now, such a regime has not been observed experimentally and was predicted only theoretically

The effects of non-universal extra dimensions on the radiative lepton flavor decays \mu\to e\gamma and \tau\to \mu\gamma in the two Higgs doublet model
We study the effect of non-universal extra dimensions on the branching ratios
of the lepton flavor violating processes \mu\to e\gamma and \tau\to \mu\gamma
in the general two Higgs doublet model. We observe that these effects are small
for a single extra dimension, however, in the case of two extra dimensions
there is a considerable enhancement in the additional contributions.Comment: 16 Pages, 9 Figure
Investigation of erosion mechanisms and erosion products in divertor armour materials under conditions relevant to ELMs and mitigated disruptions in ITER
Carbon fibre composite (CFC) and tungsten were irradiated by intense plasma streams at plasma gun facilities MK-200UG and QSPA-T. The targets were tested by plasma loads relevant to Edge Localised Modes (ELM) and mitigated disruptions in ITER. Onset condition of material erosion and properties of erosion products have been studied.Π‘-Π‘ ΠΊΠΎΠΌΠΏΠΎΠ·ΠΈΡ Ρ Π²ΠΎΠ»ΡΡΡΠ°ΠΌ Π±ΡΠ»ΠΈ ΠΏΡΠ΄Π΄Π°Π½Ρ Π²ΠΏΠ»ΠΈΠ²ΠΎΠ²Ρ ΡΠ½ΡΠ΅Π½ΡΠΈΠ²Π½ΠΈΡ

The aim of the study was to evaluate the effectiveness and safety of sodium phosphate (NaP) for colon cleaning in clinical practice. Patients and methods: 63 patients were under observation. Of these, 32 took the tablet form of Na P. The control group consisted of 31 patients who were preparing for colonoscopy using the standard method using a two-regimen for preparation of polyethylene glycol 4000. Conditions for the use of the NaP-tablet form were evaluated using a scale of criteria for compliance with the recommended treatment regimen. Results. Adequate use of the tablet form of NaP was noted in 84% of patients. The main reasons for the inadequate training were non-compliance with the intake of 1 person (3.1%), non-compliance with the diet before preparation for the study - 3 people (9.4%). Evaluation of the quality of preparation for the study was carried out according to the Boston scale [1-3]. When esophagogastroduodenoscopy was carried out, 34.3% (11 patients) of patients showed changes in gastric mucosae of the stomach, of which possible association with the reception of the tablet form of NaP in 1 (3.1%). Drug withdrawal and preparation for study 1 (3.1%) were stopped. The compliance with the use of the tablet form of NaP was high, especially among patients who previously used other preparations for intestinal preparation. Conclusions: the use of the tablet form of NaP in preparing the colon for colonoscopy when compared with other methods of purification showed good results both in the quality of the patientβs preparation and in the continuity of the patients with this preparation in preparation and in the safety of its use, which coincides with the data of other randomized research.Π¦Π΅Π»Ρ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΡ: ΠΈΠ·ΡΡΠ΅Π½ΠΈΠ΅ ΡΠ°Π·Π»ΠΈΡΠ½ΡΡ

Nanometals: Synthesis and Application in Energetic Systems
A survey of metal nanopowders or nanometals (mostly produced by electrical explosion of wires) usage in different energetic systems is carried out with the focus on nanometals combustion efficiency. Improved kinetic characteristics of chemically reacting systems (ignition, burning rate enhancement for propellants, explosives, and thermites) are typical for nanoaluminum, nAl. A weak correlation between nAl properties and the slow oxidation parameters was found as the result of a very wide scatter in powder characteristics. The burning rate enhancement was analyzed for nAl-loaded solid propellants. The most promising energetic systems are nAl-loaded solid fuels (HTPB-based, ice-based, etc.) with chemically inert matrices
