Mappings Between Annuli of Smallest p-Harmonic Energy
… without prescribing boundary values. For annuli $\A = \A(r, R)$ and $\A^* = \A(r_*, R_*)$, we seek the traction-free minimizer of the $p$-harmonic energy among homeomorphisms in Sobolev class $W^{1, p}(\A, \A^*)$. For such a mapping, the $p$-harmonic energy is defined by …

Shear stresses in turbulent flow through concentric annuli
… in fully developed turbulent flow in concentric annuli is presented. By means of a specially constructed 6 m test rig known as the 'floating sleeve', results of individual wall shear stresses, friction factors and shear stress distributions were obtained for Reynolds numbers from 25 000 to 220 …

A new method of aging gray squirrels (Sciurus carolinensis) by use of cementum annuli
… spring and summer litters, while cementum annuli were used for placing the individuals into year classes. Magnifications of lOOX - 200X were best for aging by cementum annuli. It was found that spring and summer litters could be separated as accurately with tooth development and cementum …

Development of an optimised integrated underbalanced drilling strategy for cuttings transport in gas-liquid flow through wellbore annuli.
… in gas-liquid two-phase flow through wellbore annuli. An experimental approach was applied to analyse and evaluate the relationship between the gas-liquid two-phase flow patterns and the major operational drilling parameters (gas and liquid flowrates, fluid rheology, inner pipe rotation, pipe …

Cuttings transport and hydraulics optimisation for underbalanced drilling (UBD) operations in concentric and eccentric, directional and extended reach wells.
… two-phase flows in the concentric and eccentric annuli, both with and without inner pipe rotation. The study derives and presents Reynolds number and effective viscosity equations valid for annuli flow of both Newtonian and non-Newtonian Power law, Bingham plastic and Yield power law fluids. The …

Discovery and functional analyses of new components of the apical complex and the pellicle of Toxoplasma gondii
… that involves the study of the peripheral apical annuli, the exocytic organelle microneme and the membrane occupation and recognition nexus (MORN) domain-containing proteins. The peripheral apical annuli of T. gondii, which consist of 5-7 ring-like structures at the lower edge of the apical cap, …

Turbulent fluid flow and heat transfer in annular passages with rough surfaces and moving cores.
… of fully developed fluid flows in concentric annuli with rough surfaces and moving cores, by analytically predicting the effects of surface roughness, core velocity and turbulent motion on the momentum and heat transfer characteristics of the flow, such as friction forces, velocity profiles, …

Small Venusian coronae
… which may or may not correspond to coronae annuli. These coronae are believed to be the result of gravitational relaxation of a diapir or hot-spot generated uplift. This mode of formation however, does not account for small coronae, coronae with diameters less than 200 km, that tend to …

Discrete Riemann Maps and the Parabolicity of Tilings
… describes finite tilings of quadrilaterals and annuli. It relates to several combinatorial moduli, similar in nature to the classical modulus. The first chapter surveys some of these discrete analogues. The next chapter considers appropriate extensions to infinite tilings of half-open …

Hydraulic conveyance of solid capsules
… analysing the friction head loss in eccentric annuli is presented. There have been numerous investigations concerned with friction head losses in concentric annuli. However, the correlation presented in this thesis is simpler than those given by other investigators and incorporates a wide range …

Age and Growth Determination of the Black Bullhead From Soft Fin Rays
… is then determined by counting the number of annuli. The first annulus is measured from the center (focus) of the scale to the outer margin of the first closely spaced circuli encountered and/or to where the cutting-over effects are observed. The other annuli present are measured form the …

Constant Mean Curvature 1/2 Surfaces in H2 × R
… a one-parameter family of complete, cmc 1/2 annuli that are symmetric about a reflection in the horizontal place H 2 × {0}, the horizontal catenoids. In this thesis we prove that these catenoids converge to a singular limit of two tangent horocylinders as the neck size tends to zero. We …

Snapping Turtle Life History on Lacreek Refuge, South Dakota

Growth Correlates of Several Lotic Fishes
… total length at age was estimated from scale annuli for creek chub, Semotilus atromaculatus, green sunfish, Lepomis cyanellus, sand shiner, Notropis stramineus. Correlation analysis was used to examine the relationship between independent variables and mean annual growth increment (distance …
