In this paper, the use of a cohesive-zone approach to model the mode-I fracture of adhesive joints made from a polymer-matrix composite is demonstrated. Cohesive-zone parameters were obtained by matching numerical results to experimental observations. It is shown that there is a distinction between the characteristic strength of the interface associated(More)
Selenium (Se) is an essential trace element in many life forms due to its occurrence as selenocysteine (Sec) residue in selenoproteins. However, little is known about the expression pattern of selenoproteins in the liver of layer chicken. To investigate the effects of Se deficiency on the mRNA expressions of selenoproteins in the liver tissue of layer(More)
Selenium (Se) is an essential dietary trace element, which acts as an antioxidant. Heat shock proteins (HSPs) are a family of intracellular proteins whose synthesis is greatly increased upon exposure of cells to environmental stressors including oxidative metabolites, heavy metals, amino acid analogues and so on. However, little is known about the role of(More)
Here we investigate the potential use of ALOS PALSAR L-band dual and quad polarization SAR data for improved forest structure mapping and parameter estimation. Several scenes of level 1.1 SLC data have been acquired under the DRAGON project in 2007 for the Tai-An test site of Shandong Province, P.R. China. The preliminary results for the first phase of this(More)
—Automatic detection of wipes and their frame ranges is important for the purpose of reliable video parsing and video database indexing. Wipes are difficult to detect because of the complexity and variety of the transition effects. Many of the existing wipe detection algorithms could detect only a few wipe effects. The false/miss detection problem caused by(More)
It has been implicated noncollagenous proteins act as important regulators during odontogenesis. To test the hypothesis that the roles of Dspp, Mepe, Versican and Mimecan in the regulation of odontogenesis may be complementary, comparative investigations on the localization of four proteins were performed by immunohistochemical staining using mouse first(More)
Multiple sclerosis (MS) is an inflammatory neurodegenerative disease of the central nervous system (CNS) which leads to progressive neurological disability. Our previous studies have demonstrated mitochondrial involvement in MS cortical pathology and others have documented decreased levels of the neuronal mitochondrial metabolite N-acetyl aspartate (NAA) in(More)
