The Influence of Migration Timing and Local Conditions on Reproductive Timing in Arctic-Breeding Birds.

For birds breeding in the Arctic, nest success is affected by the timing of nest initiation, which is partially determined by local conditions such as snow cover. However, conditions during the non-breeding season can carry over to affect the timing of breeding. We used tracking and breeding data from 248 individuals of 8 species and subspecies of Arctic-breeding shorebirds to estimate how the timing of nest initiation is related to local conditions like snowmelt phenology versus prior conditions, measured by the timing and speed of migration.

Ligand-Directed Actinide Oxo-Bond Manipulation in Actinyl Thiacalix[4]arene Complexes.

Understanding the chemistry of the inert actinide oxo bond in actinyl ions AnO22+ is important for controlling actinide behavior in the environment, during separations, and in nuclear waste (An = U, Np, Pu). The thioether calixarene TC4A (4-tert-butyltetrathiacalix[4]arene) binds equatorially to [AnO2]n+ (An = U, Np) forming a conical pocket that differentiates the two trans-oxo groups. The 'ate' complexes, [A]2[UO2(TC4A)] (A = [Li(DME)2], HNEt3) and [HNEt3]2[NpO2(TC4A)], enable selective oxo chemistry.

The influence of emotional labor and emotional intelligence on cesarean section decision-making among midwives and obstetricians in Kosovo: A cross-sectional study using conjoint analysis.

Introduction: Cesarean section rates continue to increase worldwide. In 2021, one in every five deliveries was delivered by cesarean section. This is particularly alarming in resource-limited countries such as Kosovo, where the rates continue to increase and vary considerably between hospitals.

"You're in an Image of a Man but Not a Man": A Qualitative Analysis of Intersectional Stigma Among Men with HIV Experiencing Subfertility in Rural Southwestern Uganda.

Many men with HIV (MWH) want to have children and may encounter HIV- and infertility-related stigma experiences. Integration of reproductive health and HIV care for men is rare. When available, safer conception care focuses on HIV prevention but lacks fertility support.

Synthesis and characterization of isostructural annulated actinocenes.

An isostructural series of four annulated actinocene complexes, M(hdcCOT) (M = Th, U, Np, Pu), is reported. The syntheses proceed through a trivalent starting material when M = U, Np, Pu with subsequent oxidation or, in the case of M = Th, directly from ThCl(DME). X-ray crystallography shows that each actinocene has molecular point symmetry in the solid state, with the metal atoms symmetrically bonded to two 10π-aromatic [8]annulene dianion rings.
