Metastable CrMnNi steels processed by laser powder bed fusion: experimental assessment of elementary mechanisms contributing to microstructure, properties and residual stress.

The complex thermal history imposed by the laser-based powder bed fusion of metals (PBF-LB/M) process is known to promote the evolution of unique microstructures. In the present study, metastable CrMnNi steels with different nickel contents and, thus, different phase stabilities are manufactured by PBF-LB/M. Results clearly reveal that an adequate choice of materials will allow to tailor mechanical properties as well as residual stress states in the as-built material to eventually redundantize any thermal post-treatment.

[ADULTS NEUROGENESIS AS A RESERVE FOR HEALTH PRESERVATION].

The article presents scientific evidence that new neurons from progenitor cells throughout life in almost all animals with a nervous system are an integral component of neuronal ontogenesis and plasticity.It has been shown that there are neural stem cells in the brain that give rise to adult neurogenesis, occurring primarily in the dentate gyrus, a subregion of the hippocampus important for learning, memory, and emotion. With age, there is a decrease in adult neurogenesis, which is associated with a decrease in cognitive functions.

[Modern features of fertility in lowand middle-income countries, including in the context of the COVID-19 pandemic].

The main issues in the problem of fertility in countries with low and middle incomes of the population are the high prevalence of complications and maternal deaths during childbirth, as well as the high incidence of such indicators of the birth of an infant with low growth and weight indicators for their gestational age, malnutrition of pregnant women and mothers, frequent abortions, short intervals between births due to the educational status of the mother and the financial wealth of households, high prevalence of teenage motherhood, low availability of cesarean section, high cost of educating children as a factor in fertility. The impact of the COVID-19 pandemic on fertility in low- and middle-income countries has been most pronounced due to disruptions in the health care system, a surge in domestic violence, teenage pregnancy and female genital mutilation.
