This paper describes an extension into three dimensions of an existing two-dimensional technique for simulating brittle solid fracture. The fracture occurs on a simulated solid created by "gluing" together space-filling polyhedral elements with compliant interelement joints. Such a material can be shown to have well-defined elastic properties. However, the "glue" can only support a specified tensile stress and breaks when that stress is exceeded. In this manner, a crack can propagate across the simulated material. A comparison with experiment shows that the simulation can accurately reproduce the size distributions for all fragments with linear dimensions greater than three element sizes.

Spontaneous rupture of flexor tendons within the carpal tunnel is rare in the absence of rheumatoid arthritis. Other predisposing conditions such as gout, infection, pisotriquetrial osteoarthritis, as well as hook of hamate fracture non-union, have previously been reported. However, tendon ruptures of the hand in the presence of acromegaly, as well as spontaneous ruptures within the carpal tunnel, have not been described in the literature.

Wet granulation is traditionally considered an empirical art. The chemical and allied industry faces range of problems, including large recycle ratios, poor quality control, surging and even the total failure of scale up from laboratory to full scale production. However, in recent years there has been a rapid advancement in understanding of the fundamental processes that control granulation behavior and product properties. This paper presents the current understanding of the key area of wet granulation process: nucleation.
