Liquefaction resistance of a sand under cyclic loading is assessed and the effects of the levels of confining pressure and static shear on resistance to liquefaction are investigated. Site-specific values of the resistance under specified levels of c

Alzheimer's disease (AD) is a debilitating form of dementia which leads to impaired memory, thinking and behavior. This work examines elemental concentrations between "normal" and AD subjects as well as the hemispherical differences within the brain.

The onset of Alzheimer's disease has been shown to affect trace element concentrations in the brain when compared to "normal" subjects in ex vivo samples. The techniques used to determine trace element concentrations were proton-induced X-ray emissio

Thirteen brain regions were dissected from both hemispheres of fifteen ‘normal’ ageing subjects (8 females, 7 males) of mean age 79±7 years. Elemental compositions were determined by simultaneous application of particle induced X-ray emissions (

“Normal” brain tissue and brain tissue affected by Alzheimer's disease has been taken from the frontal lobe of both hemispheres and their elemental compositions in terms of major, minor and trace elements compared. Brain samples were obtained fro

Ulcerative colitis (UC) is a type of inflammatory bowel disease (IBD) in which there is recurrent inflammation of the mucous membranes of the colon. Inflammation is accompanied by the production of reactive oxygen species (ROS) including, amongst oth

The brain can be divided into many anatomical regions, and the minor and trace element distribution across these regions has been shown to be heterogeneous. The various functions of the brain such as memory and language have been associated with diff

Water-soluble carbodiimide crosslinks histones 1A and 1B to histone 2A and to semi-histone A24 in chromatin from mouse cells. The identities of the histone species present in the crosslinked dimers were determined by fingerprinting. The molar ratio o
