A phenomenological model of the Landau type forms the basis for a study of elastic distortions near the spin-Peierls transition T c in CuGeO 3. The atomic displacements proposed by Hirota et al. are accounted for by the model which includes linear coupling between Cu and O distortions. Cu displacements are seen to be responsible for anomalies in the elastic properties at T c , whereas incipient...

The contamination in pleasure boatyards has been investigated. Measured concentrations of copper, zinc, lead, mercury, cadmium, tributyltin (TBT), the 16 most common polycyclic aromatic hydrocarbons (∑16 PAHs), and the seven most common polychlorinated biphenyls (∑7 PCBs) from investigations at 34 boatyards along the Swedish coast have been compiled. The maximum concentrations were 7,700 for Cu...

Temperature programmed desorption methods have been used to probe the enantioselectivity of achiral Cu(100), Cu(110), and Cu(111) single crystal surfaces modified by chiral organic molecules including amino acids, alcohols, alkoxides, and amino-alcohols. The following combinations of chiral probes and chiral modifiers on Cu surfaces were included in this study: propylene oxide (PO) on L-alanine...

Alzheimer's Disease-resemblance atrophy index (AD-RAI) is an MRI-based machine learning derived biomarker that was developed to reflect the characteristic brain associated with AD. Recent study showed AD-RAI (?0.5) had best performance in predicting conversion from mild cognitive impairment (MCI) dementia and cognitively unimpaired (CU) MCI. We aimed validate of detecting preclinical prodromal ...

In previous studies, administration of high amounts of Co decreased the proportion of MUFA in bovine milk. The present study was conducted to examine the amount of Co needed to obtain this effect. High-yielding dairy cows (n 4), equipped with ruminal cannulas, were used in a 4 × 4 Latin square design study. The basal diet consisted of concentrate mixture (9 kg/d) without added Co and grass sila...

Intra-specific variability of root biomass production (RP) of six rooted macrophytes, i.e. Juncus effusus, Phragmites australis, Schoenoplectus lacustris, Typha latifolia, Phalaris arundinacea, and Iris pseudacorus grown from clones, in response to Cu exposure was investigated. Root biomass production varied widely for all these macrophytes in control conditions (0.08 μM) according to the sampl...

Background: The Copper-T (Cu-T) Intrauterine device (IUD) is one of the oldest and most reliable forms of contraception. Its widespread use has been limited by side effects, such as heavy menstrual flow and pain on insertion. Findings suggest that the intrauterine device acts more as a contraceptive than an abortifacient, thus improving its acceptability. Objectives: To determine the proportion...
