We present first results of our on-going BIMA Key Project: imaging the CO(1-0) emission from a sample of 10 LIRGs that are at various merging stages, with special emphasis on systems apparently in the early/intermediate stages of merging. We present here CO images with ∼ 5 resolution. An important result is the recognition of a plausible pre-starburst phase in some early LIRG mergers (e.g., Arp...

A scenario of galaxy formation is put forward which is a process of sudden condensation just after recombination. It is essentially based on the fact that the cosmic matter gas after recombination is a general relativistic Boltzmann gas which runs within a few 10 years into a state very close to collision–dominated equilibrium. The mass spectrum of axially symmetric condensation ”drops” extends...

An analysis of a ROSAT/HRI observation of the optically rich, gravitationally lensing galaxy cluster CL0500-24 (or Abell S0506) is presented. We show that the X-ray luminosity of this supposedly rich cluster is relatively low at 1.1 −0.1 × 10 44 erg/s in the ROSAT band, the bolometric X-ray luminosity is 2.0 −0.7 × 10 44 erg/s. The X-ray emission is strongly correlated with the northern subconc...

In this research, mechanical alloying was used to produce Ti-50Al, Ti-45Al-5Cr and Ti-45Al-5W (at%) alloys. The effect of ternary addition (Cr and W) on microstructure and production efficiency of TiAl alloy were investigated. Alloying was performed in a planetary mill and the milling time varying from 5 to 70h. The structural evaluation in these powders was done by X-ray diffraction (XRD) tech...

This article presents an efficient algorithm for computing a 10-point DFT. The proposed reduces the number of multiplications at cost slight increase in additions comparison with known algorithms. Using DFT harmonic power system analysis can improve accuracy and reduce errors caused by spectral leakage. paper compares computational complexity L×10M-point 2M-point

We present the galaxy cluster autocorrelation function of 277 galaxy cluster candidates with 0.25 ≤ z ≤ 1.5 in a 7 deg2 area of the IRAC Shallow Cluster Survey. We find strong clustering throughout our galaxy cluster sample, as expected for these massive structures. Specifically, at 〈z〉 = 0.5 we find a correlation length of r0 = 17.40+3.98 −3.10 h −1 Mpc, in excellent agreement with the Las Cam...

Certain monoclonal antibodies (MoAbs) specific for platelet membrane glycoproteins are known to be capable of activating platelets, and it is generally thought that platelets from normal subjects are equally susceptible to stimulation by such MoAbs. We found that platelets from 20 normal donors varied significantly in their sensitivity to three IgG1 murine MoAbs specific for membrane glycoprote...

Winter wheat is the most valuable agricultural crop, which occupies one of first places in balance grain crops Central region Non-Chernozem zone Russia. Year after year, there an increasing need to expand production products, can be provided by varieties that give high and stable yields over years. Creation environmentally plastic a promising popular direction breeding work recent The evaluatio...
