In this paper we describe the potential of employing the concept of thermodynamic entropy generation to assess degradation in processes involving metal fatigue. It is shown that empirical fatigue models such as Miner’s rule, Coffin-Manson equation, and Paris law can be deduced from thermodynamic consideration.

Management of airway in patients who have Coffin-Siris syndrome (CSS) is often problematic because most of these patients have difficult airway. NTI via C-MAC VL is an useful alternative to direct laryngoscope for orotracheal intubation in airway and anesthetic management in a case of CSS. Alternative airway devices should be readily available.

Because of the small particle size, orientation-dependent diffusion measurements in microporous materials remains a challenging task. We highlight here the potential of micro-imaging by interference microscopy in a case study with MFI-type crystals in which, although with different accuracies, transient concentration profiles in all three directions can be observed. The measurements, which were...

Large bedforms in the nearshore (with heights of 10 – 50 cm and lengths of 1-10 m) are observed to occur frequently and to be ubiquitous throughout the surf zone (e.g., Clifton et al. 1971, Gallagher et al. 2002, Hay and Wilson 1994, Thornton et al. 1998). However, their dynamics are poorly understood and they are generally neglected in models of sediment transport, morphology change and nearsh...
