Cathode strip chamber for CMS ME1/1 endcap muon station

Seventy-six serial ME1/1 cathode strip chambers have been produced in Dubna. These chambers are the coordinate detectors of the first muon station of the CMS detector at CERN. This paper describes the design of the chamber, its main mechanical parameters, and the results of the cosmic ray test. The text was submitted by the authors in English.

Russian Chemical Bulletin - The cytotoxicity of complex 69mZnLigCl2 (Lig is N-(5,6-dihydro-4H-1,3-thiazin-2-yl) benzamide) against the K-562 cell line (chronic myeloid leukemia) was considered in...     

A new project for the investigation of unsolved problems of ddµ and pdµ catalysis in D2 and H/D mixtures

We propose to study a number of open problems in ddµ and pdµ fusion using the new high-pressure ionization chamber for charged particle identification in coincidence with the n-/e-counter array for the detection of neutrons and µ-decay electrons. Our first objective will be a precise measurement of the absolute rates of resonant and non-resonant ddµ formation in D₂ and HD-gases and their temperature dependence from 40 to 350 K. Both output channels of the dd-reaction:³He + n and t + p will be observed and their ratio sensitive to contributions of S and P-waves will be determined. Simultaneously, we shall investigate the pdµ-cycle and determine the absolute pd-fusion yields in different molecular H/D compositions, observing tritons from nuclear muon capture in³Heµ: pdµ ³Heµ + . We have developed a special system for the preparation of HD-gas with high concentration (96%) of HD and a purity (10^–6).     

Numerical Models of the Vertical Turbulent Exchange in Stably Stratified Water Body: II. Results of Numerical Experiments

On the basis of the developed models [1], numerical modeling of the problem on penetration of a turbulent layer of mixed liquid in linearly stratified medium under constant shear stress is performed. The calculation results are in satisfactory agreement with the known experimental data and show a significant effect of anisotropy of the flow on its main characteristics.     

Modeling of Charge Transfer Excited States of Titanocene Dicarboranyl

Modern quantum-chemical methods have been used to model and assign the bands of the electronic spectrum in the near UV–visible region of a structurally intricate metal complex with organometallic σ and π bonds. The properties of the frontier and nearest molecular orbitals and the nature of the electronic transitions with ligand-to-metal charge transfer have been estimated.     

Nitroguanyl azide

Crystals of the title compound, nitro­carbam­imidoyl azide, CH₂N₆O₂, consist of two symmetry‐independent mol­ecules and the structure is stabilized by intra‐ and intermolecular hydrogen bonds. The mol­ecule possesses a nitr­imine structure.
