Diffusion is important in controlling local solute transport and reactions in unsaturated soils and geologic formations. Although it is commonly assumed that thinning of water films controls solute diffusion at low water contents, transport under these conditions is not well understood. We conducted experiments in quartz sands at low volumetric water contents (θ) to quantify ion diffusion within adsorbed films. At the lowest water contents, we employed fixed relative humidities to control water films at nm thicknesses...

From epidemiological studies and studies done evaluating microbiomes in infants, there is a strong signal that the infants born by elective cesarean section (C-section) develop microbiota that differs from those babies born by vaginal delivery. Epidemiological studies show increased odds ratios for the development of immunological disorders such as type 1 diabetes, celiac disease, asthma, allergic diseases as well as metabolic diseases such as obesity in babies born by C-section. These are interesting associations, and if supported by additional studies that rigorously control for confounding factors, they will have major public health implications...

BACKGROUND: Metabolic syndrome (MetS) identifies subjects with increased risk of cardiovascular disease when they have a combination of insulin resistance, obesity, hypertension, hyperglycemia, low high-density lipoprotein cholesterol (HDL-C), and elevated triglycerides (TGs). Increasing evidence suggests that vitamin D deficiency could be associated with diabetes and MetS. The aim is to assess if 25-hydroxyvitamin D (25-OHD) is correlated with cardiovascular risk components of MetS. METHODS: A cross-sectional study involved 124 diabetic patients with MetS according to International Diabetes Federation definition...

OBJECTIVE: The use of drugs with intrinsic anticholinergic properties is widespread among old age persons. A growing body of evidences suggest that a high anticholinergic burden is associated with physical and cognitive impairment. However, the association between anticholinergic drug use and functional status is still poorly investigated, particularly among subjects with initial cognitive impairment. DESIGN: Cross-sectional study examining the association between drug-related anticholinergic burden and functional status in cognitively healthy (CH) (n=691), mild cognitive impairment (MCI) (n=541) or mild Alzheimer's diseases (AD) (n=1127) subjects...

The term dark triad refers to the constellation of narcissism, Machiavellianism, and psychopathy. Over the past few years, the concept has gained momentum, with many researchers assuming that the dark triad is a prominent antecedent of transgressive and norm-violating behavior. Our purpose in this meta-analytic review was to evaluate (a) interrelations among narcissism, Machiavellianism, and psychopathy; (b) gender differences in these traits; (c) how these traits are linked to normal personality factors; and (d) the psychosocial correlates of the dark triad...

Operational stability is the main issue hindering the commercialisation of perovskite solar cells. Here, a long term light soaking test was performed on large area hybrid halide perovskite solar cells to investigate the morphological and chemical changes associated with the degradation of photovoltaic performance occurring within the devices. Using Scanning Transmission Electron Microscopy (STEM) in conjunction with EDX analysis on device cross sections, we observe the formation of gold clusters in the perovskite active layer as well as in the TiO2 mesoporous layer, and a severe degradation of the perovskite due to iodine migration into the hole transporter...
