A dimensional analysis of the momentum balance in circulating fluidized beds reveals that the fluid dynamics of these units is governed by five dimensionless groups. However, it is not possible to match the hydrodynamics of a range of industrial circulating fluidized beds using a single laboratory facility operated at ambient temperature and pressure. To address this difficulty, Glicksman, et a...

The outcome of a bone fracture partly depends upon the mechanical environment experienced by the fracture callus (reparative tissue) during the healing. Therefore biomechanics of bone fracture healing has been examined in many clinical or biological, mathematical or finite element studies (Cheal et al. 1991, DiGioia et al. 1986, Claes et al. 1999, Doblaré et al. 2004 and Oh et al. 2010). Most o...

Introduction Image registration is an important tool in medical image analysis, particularly in functional MRI (fMRI) and gadolinium contrast uptake in breast imaging. The most common methods of registering two images are image domain based iterative searches for optimal shift and rotation parameters.[1] Maas et al [2], and Calhoun et al[3], have published a frequency domain algorithm (DART) th...

This paper analyzes how US presidential candidates should allocate resources across states to maximize the probability of winning the election, by developing and estimating a probabilisticvoting model of political competition under the Electoral College system. Actual campaigns act in close agreement with the model. There is a 0.9 correlation between equilibrium and actual presidential campaign...

The success of assisted reproduction, although gradually increasing over the years, is still less than satisfactory. Many couples have benefited from this treatment; many have also been left frustrated following multiple failed attempts (Bulent Urman et al. 2005). Repeated implantation failure (RIF), defined as three or more failed IVF attempts or failure of IVF after cumula- Abstracts of the 5...

As businesses move to generating more documents in purely digital form there is a need for providing digital archiving solutions to complement traditional paper archives. This thesis describes the investigation into the viability of a secure digital archive. Issues treated include, long-term data storage, secure transfers over a public network and an overview of current archiving laws. A protot...

Observational evidence of a hydrodynamically evaporating upper atmosphere of HD209458b (Vidal-Madjar et al. 2003; 2004) and recent theoretical studies on evaporation scenarios of “Hot Jupiters” in orbits around solar-like stars with the age of the Sun indicate that the upper atmospheres of short-periodic exoplanets experience hydrodynamic blow-off conditions resulting in loss rates of the order...

Severa1 storage proteins of potato (Solanum tuberosum L.) tubers have been identified, including severa1 proteinase inhibitors such as proteinase inhibitor I and I1 and the 22-kD protein group (Melville and Ryan, 1972; Bryant et al., 1976; Suh et al., 1990). The 22-kD cathepsin D inhibitor protein of potatoes (PDI) has been purified and characterized (Mares et al., 1989). This glycosylated prot...
