Articular cartilage has poor healing ability and cartilage injuries often evolve to osteoarthritis.Cell-based strategies aiming to engineer cartilaginous tissue through the combination of biocompatible scaffolds and articular chondrocytes represent an alternative to standard surgical techniques.In this context, perfusion bioreactors have been intro

In this paper, the three-dimensional sphere packing problem is solved by using a dichotomous search-based heuristic.An instance of the problem is defined by a set Syrups of $ n $ unequal spheres and an object of fixed width and height and, unlimited length.Each sphere is characterized by its radius and the aim of the problem is to optimize the leng

Rainfall is the main factor leading to the landslide of expansive soil slope.To deeply understand the instability mechanism of expansive soil slope under rainfall conditions, it is necessary to Handbag clarify the strength attenuation mechanism of expansive soil caused by water absorption and swelling.Therefore, the improved constant volume direct
