Mild form of iron deficiency anemia and a latent iron deficiency as a border – line state in infants aged under 2 years

The mentioned forms of iron deficiency in infants aged 6 mos - 2 yrs were found to be wide – spread, almost blurred clinically, and of high spontaneous reversity. Therefore, failing to affect the children’s growth, physical development and the morbidity rate these disorders could be considered as a border–line stete

Universal description of the rotational-vibrational spectrum of three particles with zero-range interactions

A comprehensive universal description of the rotational-vibrational spectrum for two identical particles of mass $m$ and the third particle of the mass $m_1$ in the zero-range limit of the interaction between different particles is given for arbitrary values of the mass ratio $m/m_1$ and the total angular momentum $L$. If the two-body scattering length is positive, a number of vibrational states is finite for $L_c(m/m_1) \le L \le L_b(m/m_1)$, zero for $L>L_b(m/m_1)$, and infinite for $L<L_c(m/m_1)$. If the two-body scattering length is negative, a number of states is either zero for $L \ge L_c(m/m_1)$ or infinite for $L<L_c(m/m_1)$. For a finite number of vibrational states, all the binding energies are described by the universal function $\epsilon_{LN}(m/m_1) = {\cal E}(\xi, \eta)$, where $\xi=\displaystyle\frac{N-1/2}{\sqrt{L(L + 1)}}$, $\eta=\displaystyle\sqrt{\frac{m}{m_1 L (L + 1)}}$,and $N$ is the vibrational quantum number. This scaling dependence is in agreement with the numerical calculations for $L > 2$ and only slightly deviates from those for $L = 1, 2$. The universal description implies that the critical values $L_c(m/m_1)$ and $L_b(m/m_1)$ increase as $0.401 \sqrt{m/m_1}$ and $0.563 \sqrt{m/m_1}$, respectively, while a number of vibrational states for $L \ge L_c(m/m_1)$ is within the range $N \le N_{max} \approx 1.1 \sqrt{L(L+1)}+1/2$

Organic Cation Substitution in Hybrid Perovskite CH₃NH₃PbI₃ with Hydroxylammonium (NH₃OH⁺): A First-Principles Study

The exceptional success of hybrid perovskite materials in the next generation of photovoltaics has attracted the interest of scientists across many fields in photophysics. Structural and optoelectronic properties are of main importance when searching for potential compounds beyond photovoltaics or as top-cell absorbers. In this article, we theoretically study the thermodynamic stability and electronic properties of organic cation substituted MAPbI₃ with hydroxylammonium ions. Results from structural relaxations are compared to predictions from Goldschmidt tolerance factors. Our findings evidence that size effects and the initial orientation of the central cation result in strongly alternated octahedral distortions and markedly different optoelectronic properties. The latter becomes noticeable mainly due to band gap variations and significant frontier orbital splitting, which is observed in the case of relativistic calculations and seems to highly depend on the inorganic network deformation
