Study of Correlation of Structural Features in the Porous TiNi-based Materials Obtained by Sintering with the Integration Process of Bone Marrow Cell Populations

The structural features of porous-permeable TiNi-based materials obtained by sintering in depending on the temperature have been studied. It is shown that a material obtained at the sintering temperature of T2=1250 °C and time t=40 min has an optimal degree of sintering and relates to finely porous materials with the porosity of 55 %. A positive dynamics of development of bone marrow cells in the TiNi-based sintered material was proved. It is noted that the finely porous macrostructure with developed rough surface of pore walls provides favorable conditions for development of cell populations. When the 21 day of cultivation a dense formed tissue on basis of bone marrow cells observes in the material pores

GOODS-ALMA 2.0: Starbursts in the main sequence reveal compact star formation regulating galaxy evolution prequenching

Compact star formation appears to be generally common in dusty star-forming galaxies (SFGs). However, its role in the framework set by the scaling relations in galaxy evolution remains to be understood. In this work we follow up on the galaxy sample from the GOODS-ALMA 2.0 survey, an ALMA blind survey at 1.1 mm covering a continuous area of 72.42 arcmin2 using two array configurations. We derived physical properties, such as star formation rates, gas fractions, depletion timescales, and dust temperatures for the galaxy sample built from the survey. There exists a subset of galaxies that exhibit starburst-like short depletion timescales, but they are located within the scatter of the so-called main sequence of SFGs. These are dubbed starbursts in the main sequence and display the most compact star formation and they are characterized by the shortest depletion timescales, lowest gas fractions, and highest dust temperatures of the galaxy sample, compared to typical SFGs at the same stellar mass and redshift. They are also very massive, accounting for ∼60% of the most massive galaxies in the sample (log(M*/M⊙) > 11.0). We find trends between the areas of the ongoing star formation regions and the derived physical properties for the sample, unveiling the role of compact star formation as a physical driver of these properties. Starbursts in the main sequence appear to be the extreme cases of these trends. We discuss possible scenarios of galaxy evolution to explain the results drawn from our galaxy sample. Our findings suggest that the star formation rate is sustained in SFGs by gas and star formation compression, keeping them within the main sequence even when their gas fractions are low and they are presumably on the way to quiescence
