A healthy uterine environment is essential for establishing and maintaining pregnancy normal embryo development after insemination. In this context, the primary objectives of study were to assess genetic background vaginal discharge score (VDS) traits during voluntary waiting period in Holstein cows identify genomic regions candidate genes influencing postpartum health based on integration phenotypic, genomic, transcriptomic data sets. Genetic parameters 5 VDS defined according lactation...
We use $^{75}$As nuclear magnetic resonance (NMR) to investigate the local electronic properties of Ba(Fe$_{1-x}$Ru$_{x}$)$_2$As$_2$ ($x =$ 0.23). find two phase transitions, antiferromagnetism at $T_N \approx$ 60 K and superconductivity $T_C 15 K. Below $T_N$, our data show that system is fully magnetic, with a commensurate antiferromagnetic structure moment 0.4 $\mu_B$/Fe. The spin-lattice relaxation rate $1/^{75}T_1$ large in state, indicating high density itinerant electrons induced by...
We report nuclear magnetic resonance (NMR) studies of the intercalated iron selenide superconductor ${(\text{Tl},\text{Rb})}_{y}{\text{Fe}}_{2\ensuremath{-}x}{\text{Se}}_{2}$ (${T}_{c}=32$ K). Single-crystal measurements up to 480 K on both ${}^{77}$Se and ${}^{87}$Rb nuclei show a superconducting phase with no order. The Knight shifts $K$ relaxation rates $1/{T}_{1}T$ increase very strongly temperature above ${T}_{c}$, before flattening at 400 K. quadratic $T$-dependence perfect...
We present a high-pressure NMR study of the overdoped iron pnictide superconductor ${\mathrm{NaFe}}_{0.94}{\mathrm{Co}}_{0.06}\mathrm{As}$. The low-energy antiferromagnetic spin fluctuations in normal state, manifest as Curie-Weiss upturn spin-lattice relaxation rate $1/^{75}T_{1}T$, first increase strongly with pressure but fall again at $P>{P}_{\mathrm{opt}}=2.2\text{ }\text{ }\mathrm{GPa}$. Neither long-ranged magnetic order nor structural phase transition is encountered up to 2.5 GPa....
We report both 77Se and 87Rb NMR studies on Tl0.47Rb0.34Fe1.63Se2 single-crystalline superconductors (T_c about 32 K). Singlet superconductivity is decisively determined by a sharp drop of the Knight shift K(T) below T_c, after subtracting superconducting diamagnetic effect. However, Hebel-Slichter coherence peak T_c not observed in spin-lattice relaxation rate 1/T_1, even with low in-plane field 2.6 Tesla. Just above no evidence low-energy spin fluctuation found sites. Upon warming,...
