Some Comments on Baryonic States

Cosmic strings in an open universe with baryonic and nonbaryonic dark matter.

We study the eeects of cosmic strings on structure formation in open universes. We calculate the power spectrum of density perturbations for two class of models: one in which all the dark matter is non baryonic (CDM) and one in which it is all baryonic (BDM). Our results are compared to the 1 in 6 IRAS QDOT power spectrum. The best candidates are then used to estimate , the energy per unit leng...

Formation of Large Structures in the Acceleration Universe with a Hybrid Expansion Law

In the current paper, we have studied the effect of dark energy on for-mation where dark energy exists in the background. For this purpose, we used both WMAP9 and Planck data to study how the radius changes with redshift in these mod-els. We used different data sets to fix the cosmological parameters to obtain a solution for a spherical region under collapse. The mechanism of structure formation f...

Baryonic thermal fluctuations in finite temperature QCD Vicente Azcoiti and Angelo

We show how, contrary to physical intuition, thermal fluctuations of physical states having a non-vanishing baryonic number can be fully neglected in the thermodynamics of QCD at any physical temperature. We also discuss on the consistency between our results and the CPT theorem. The last part of this article is devoted to comment some interesting physical features which follow from this result.

Recent Trends in Archaeological Theory: Some Comments

 This paper selectively reviews some recent themes in archaeological theory:  a philosophical pragmatism, a turn to materiality, and understanding the past in the context of the present.  It concludes with some reflective comments on the author’s Archaeological Theory:  An Introduction, in advance of the third revised edition.
