Tribocorrosion is a type of material degradation, which results from the combined action of wear and corrosion. Orthopedic applications, artificial joints, e.g. hip and knee prostheses, include bearing surfaces where the material is subjected to sliding wear and immersed in the body fluid are ...
Alloysare compounds consisting of more than one metal. Adding other metals can affect the density, strength, fracture toughness, plastic deformation, electrical conductivity and environmental degradation. 合金是由一种以上金属组成的混合物。加一些其它金属能影响密度、强度、断裂韧性、塑性变形、导电性以及环境...

RNA degradation was estimated by calculating a 3′ bias ratio. Specifically, we first counted the number of reads per exon and then annotated each exon with its corresponding gene ID and exon number using htseq-count. Using these annotations, we measured the frequency of genes for which all ...

A material allowing twice the charge transfer as a vacuum has a dielectric constant of 2, etc. The nuances of different capacitor types are, for the most part, determined by the characteristics of the dielectric used and the method by which a given device is constructed. All dielectric ...
The termcorrosionis generally used to describe the degradation of a substance or material over time due to some form of reaction, but in fact, there are more specific types of corrosion that can be differentiated by how they are caused, where they occur, and how they appear. The main types...
, from an application of the model to decalcified cement pastes, it is shown that that the decalcification of the C-S-H phase is the primary source of the macroscopic elastic modulus degradation, that dominates over the effect of the dissolution of Portlandite in cement-based material systems....
The high activities of these soil enzymes and active soil microorganisms can contin- uously drive the degradation and mineralization of soil organic matter and provide the stable supply of nitrogen nutrients etc. for the growth of plants and thus, they are favorable for the growth, development ...
Chapter 1: What are the properties of polyethylene foams?Polyethylene foam is a valuable closed-cell thermoplastic foam material. A closed-cell foam consists of tiny dense cells enclosed by its walls. The cells sit close to each other, but they are not interconnected. Hence, closed-cell foams...
