Product formulation and in vitro dissolution characteristics of sustained-release chewable tablet dosage
forms are presented in chapter one of this thesis. In vivo
single dose and multiple dose studies of two
sustained-release formulations as well as one conventional
dyphylline formulation are described in chapter two. The
pharmacokinetics of dyphylline following...
Fe25Co25Ni25Cr25-XMoX High Entropy Alloys were fabricated in mini arc-melter and then cast into 4mm diameter cylinders by injection casting technique and 1cm diameter cylinders by water quenching technique. Heat transfer modeling during solidification of FeCoNiCr HEA was simulated. Combining X-Ray Diffraction, Optical Microscopy, Scanning Electron Microscope, Energy Dispersive X-ray analysis,...
Fire-history reconstructions are based on tree-ring records that span the last few centuries and charcoal data
from lake-sediment cores that extend back several thousand years. The two approaches have unique strengths and
weaknesses in their ability to depict past fire events and fire regimes, and most comparisons of these datasets...
Forest managers have little information of the effects of common restoration treatments, thinning and burning, on dead woody material (DWM) dynamics in fire-suppressed forests. Fine woody debris (FWD; 0.6–29.9 cm), coarse woody debris (CWD; ≥30.0 cm), and snags (≥5 cm) were inventoried and mapped in eighteen 4 ha plots before...
Hydroxyurea (10mM) blocks the exponential growth of Tetrahymena
pyriformis (GL-I) populations by arresting progress through the cell
cycle once the cells enter S-phase. Autoradiographic analysis reveals
that HU reduces the uptake of tritiated thymidine (³H-TdR) into
macronuclear DNA in S-phase cells to about 1/5 of that in untreated
S-phase cells....
A pilot scale demonstration of a biological permeable barrier was conducted in a pentachlorophenol-contaminated aquifer at a wood preserving facility. A permeable reactor was constructed to fit within a
large diameter well. Arranged in series, a cylindrical reactor 24" x 36" (0.61 x 0.91m) (diameter x height)
was partitioned to...
Quince (Cydonia oblonga Mill.) is widely used as a dwarfing rootstock for pear
{Pyrus communis L.). The disadvantage of this rootstock is its inefficient uptake of Fe,
resulting in leaf chlorosis. Application of tissue culture and gene transfer techniques may
lead to production of quince clones with improved Fe efficiency....
The warm pool region of the western tropical Pacific is of particular interest to atmospheric dynamics because it represents a significant source of energy to the atmosphere. A better understanding of heat transfer driven by mesoscale and turbulent circulations within this region could lead to improved global circulation models, and...
