the particle morphology and decreased infectivity and re verse transcriptase activity of the virions. The cream fraction was more effective in the physical, biochemical, and biological degradation of the virions than the whole or skimmed milk, but the nature of the degrading component(s) has not been determined. The significance of the destructive effect of human milk upon mouse mammary tumor v...

Traditional manufacturing solutions, based on centralized structures, are ineffective in unpredictable and volatile scenarios. Recent manufacturing paradigms, such as Holonic Manufacturing Systems, handle better these unpredictable situations but aren’t able to achieve the performance optimization levels displayed by the classical centralized solutions when the system runs without perturbations...

We consider degrading engineering systems monitored by sensors. Since accurate information is crucial for predicting system health condition and the subsequent decision-making, considering effect of sensor degradation highly important to determine justified reliability characteristics such as remaining useful life (RUL). Although concept has been introduced previously in literature, estimation ...

Synthetic dyes are complex aromatic compounds used in many industries like paper, printing, textile, food and cosmetics [1]. The major synthetic dyes include azo, triphenylmethane, anthraquinone and metal dyes. They are reported to be carcinogenic and thus their safe release into the environment poses a threat to public health. About 10-15% of the substrate unbound dyes from the industries are ...

An iterative adaptive weighted filtered backprojection (FBP) approach was applied to our photoacoustic imaging (PAI) of the optical absorption in biological tissues from limited-view data. By using an image-based adaptive weighted PAI reconstruction, we can modify the defect of the artifacts degrading the quality of the image. Results of numerical simulations demonstrated that the proposed algo...

It is generally believed that structural changes in the extracellular matrix are necessary for cell migration, wound repair and tissue remodeling. Matrix metalloproteases are the major family of proteolytic enzymes responsible for degrading extracellular matrix components, and have been implicated in all of these biological processes. They form part of a superfamily of zinc peptidases known as ...
