Abstract Ancient murals are important cultural heritages for our exploration of ancient civilizations and great research value. Due to long-time exposure the environment, often suffer from damage (deterioration) such as cracks, scratches, corrosion, paint loss, even large-region falling off. It is an urgent work protect restore these damaged murals. Mural inpainting techniques refer virtually f...

RNA and protein syntheses in axes excised from dry soybean (Glycine max L.) seeds at different levels of deterioration were assayed. Low rates of protein synthesis in slightly deteriorated seeds were not due to losses in ribosomal or soluble fraction activities. However, the lowered rates of RNA and protein syntheses of deteriorated seeds were associated with reduced ATP content of the tissues....

BACKGROUND Chronic congestive heart failure is a complex condition that leads to dysfunction in the peripheral microcirculation. We have previously shown that vascular reactivity is reduced with increasing age. In this study, we examined a group of very old patients with severe chronic heart failure to test the hypothesis that vascular function is further compromised by a combination of heart f...

electrical steels are important alloys widely used in electrical instruments. the magnetic properties and low core loss of grain oriented silicon steels are closely related to the sharpness of goss texture ({110} ).the direction of is the softest direction for magnetism.  in this work, the microstructure and dependence of orientation density along the major texture fibers on the applied cold ro...
