Concomitant reactions to palladium chloride (PdCl2), sodium tetrachloropalladate (Na2PdCl4), and nickel hexahydrate sulphate (NiSO4·6H2O) are very common during patch testing and have mainly been explained by cross-sensitisation. Whether there is variation in reactivity to palladium or covariation to nickel and palladium is not known. The aim of this study was to investigate the variation in patch
Sensitivity tests were conducted using a state-of-the-art aerosol–cloud to investigate the key microphysical and dynamical mechanisms by which solid aerosols affect glaciated clouds. The tests involved simulations of two contrasting cases of deep convection—a tropical maritime case and a midlatitude continental case, in which solid aerosol concentrations were increased from their pre-industrial (1
Fast directional growth is a necessity for the young seedling; after germination, it needs to quickly penetrate the soil to begin its autotrophic life. In most dicot plants, this rapid escape is due to the anisotropic elongation of the hypocotyl, the columnar organ between the root and the shoot meristems. Anisotropic growth is common in plant organs and is canonically attributed to cell wall anis
Glucose is the major energy substrate during embryogenesis and the embryo is dependent on glucose from the maternal circulation to ensure normal metabolism and growth. The placenta plays a key role in this nutrient transfer in mammals, both during embryogenesis and after the development of the chorio-allantoic placental circulation. Maternal hypoglycaemia is accompanied by foetal hypoglycaemia and
The main aims of this work were: 1) to increase the understanding of the segregation process that occurs during a segregation test that follows the ASTM sifting segregation procedure, and 2) to understand the effect of powder load, fines mass fraction and particle diameter ratio on the segregation of ideal blends. Binary blends of microcrystalline cellulose particles (mean diameter ranging from 16
