UNLABELLED This study was performed to prospectively evaluate fast PET/CT imaging protocols using lutetium oxyorthosilicate (LSO) detector technology and 3-dimensional (3D) image-acquisition protocols. METHODS Fifty-seven consecutive patients (30 male, 27 female; mean age, 58.6 +/- 15.7 y) were enrolled in the study. After intravenous injection of 7.77 MBq (0.21 mCi) of (18)F-FDG per kilogram...

BACKGROUND While improvements in nursing practice environments are considered essential to address the nursing shortage, relatively little is known about the nursing practice environments in most hospitals. OBJECTIVES The objectives of this study are to describe variations in nursing practice environments across hospitals and to examine their associations to hospital bed size, community size,...

Effects of rapid heat transfer using a fluidized bed on the heat-treating response of Al-Si-Mg alloys (both unmodified and Sr modified) were investigated. The heating rate in the fluidized bed is greater than in conventional air convective furnaces. Particle size analyses of eutectic Si showed that the high heating rate during fluidized bed solution heat treatment causes faster fragmentation an...

[1] Partial transport is documented in the gravel bed channel of Carnation Creek using magnetically tagged stones. For four flood peaks the active proportion of surface grains was used to map streambed areas into distinct units of three different levels of grain entrainment. In partially mobile regions of the bed, the active proportion of surface grains declines with grain size. As flow increas...

The Sydney octopus (Octopus tetricus) occurs in unusual numbers on a shell bed of its prey remains that have accumulated as an extended midden where additional octopuses excavate dens. Here, O tetricus are ecosystem engineers, organisms that modulate availability of resources to other species and to their own species by causing physical state changes in materials. A community of invertebrate gr...

BACKGROUND Myanmar lies in the Greater Mekong sub-region of South-East Asia faced with the challenge of emerging resistance to artemisinin combination therapies (ACT). Migrant populations are more likely than others to spread ACT resistance. A vital intervention to reduce malaria transmission, resistance spread and eliminate malaria is the use of bed nets. Among seasonal and stable migrants in ...

Akademisk avhandling som med tillstånd av KTH i Stockholm, framlägges till offentlig granskning för avläggande av Teknisk Doktorsexamen, tisdagen den 20 december kl. iii To my beloved parents iv v Abstract This study focuses on two different types of micro-particles selected from different stages off iron and steelmaking processes. These particles are dust particles generated due to mechanical ...

Drying of green peas in a Fluidized Bed Dryer (FBD) with inert particle, heated by combined sources of hot air and InfraRed (IR) radiation, has been experimentally and theoretically studied. For this purpose, an experimental set up was constructed. This setup was composed of a cylindrical bed dryer containing some inert particles which are fluidized by hot air. Some infrared lamps were also pla...

A systematic analysis on the use of the lattice Boltzmann method (LBM) for predicting the permeability of packed beds is presented. A filtration rig is used to obtain permeability measurements of beds of glass beads, sand and crushed minerals. Subsequently, X-ray microtomography is employed to image bed samples for use as input to LBM calculations. Uncertainties in accuracy and reliability of p...
