Packed-Bed Photocatalytic Reactors. A Packing Structure Model and Its Experimental Validation with Computerized Tomography
(American Chemical Society, 2004-12)
A statistical model is proposed for the description of the spatial structure of a packed bed of spherical-like particles in terms of one- and two-bead distribution functions. This is the first step toward the full modeling ...
Methodological analysis of gamma tomography system for large random packed columns
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
Gamma ray tomography experiments have been carried out to detect spatial patterns in the porosity in a 0.27 m diameter column packed with steel Rashig rings of different sizes: 12.6, 37.9, and 76 mm. using a first generation ...
Protein chain packing and percolation threshold
(2006)
The major factor that drives a protein chain toward collapse and folding is the hydrophobic effect. Amino acids with apolar side chains join forming a solvent-shielded hydrophobic core. This process pack the structure in ...
Perineal Analgesia With an Ice Pack After Spontaneous Vaginal Birth: A Randomized Controlled Trial
(WILEY-BLACKWELL, 2011)
Methods: We conducted a randomized controlled trial at the Amparo Maternal Birth Center in Sao Paulo, Brazil. Study participants included 114 nulliparous women divided into 3 groups (n = 38 per group): experimental (ice ...
