Chemical pressures in crystalline solids
… to construct 1D, 2D and 3D maps of chemical pressures. These maps serve to clearly identify the regions responsible for attractions and repulsions that give rise to cohesion in all explored crystalline systems. Bonds, lone pairs, domains of dispersive interactions or steric repulsions can be …

A DEVICE FOR ASSESSING INTRACRANIAL PRESSURES
… has been designed to measure intracranial pressures in infants for the specific purpose of providing a clinical device to aid in the early detection of abnormal intracranial pressures. It is also useful in monitoring the intracranial pressure following surgery of the central nervous system. …

Air Circulation Under Reduced Atmospheric Pressures
… sensors</p> <p>became non-linear at various pressures below 25 kPa. We introduced mathematical</p> <p>calibration corrections and found that sensor data linearity could be extended to a greater</p> <p>range of pressures. These calibration corrections allow for sensor calibration …

Phase equilibrium studies at normal pressures
… mixtures at atmospheric and sub-atmospheric pressures. The method gives isothermal data which can be obtained rapidly. Only measurements of total pressure are made as a direct function of composition of synthetic liquid phase composition, the vapour phase composition being deduced through the …

Phase equilibrium studies at moderate pressures
… This novel still is designed to work at pressures up to 35 bar and for the measurement of both isothermal and isobaric vapour-liquid equilibrium data. The equilibrium still was first commissioned by measuring the saturated vapour pressures of pure ethanol and cyclohexane in the …

Dynamic soil pressures on deeply embedded structures
… Simple approximate expressions for the dynamic pressures and associated forces induced by ground shaking on a rigid, straight, vertical wall retaining a semi-infinite, uniform viscoelastic layer are developed, and comprehensive numerical data are presented which elucidate the effects of the …

Cognitive and communicative pressures in natural language
Why do languages have the words they do instead of some other set of words? In the first part of this thesis, I argue that cognitive and communicative demands strongly influence the structure of the lexicons of natural languages. It is known that words in natural language are distributed such that …

The supply chain response to environmental pressures
… including the characteristics of environmental pressures and market drivers, to a general approach for developing operational supply chain processes that may deliver environmental and economic performance improvements. Findings from a series of semi-structured interviews indicate that there are …

Ecological Pressures Selecting for Singing Behavior in Primates
This dissertation explores the social, behavioral, and habitat based influences on the evolution of elaborate vocalizations in primates. The goals of this project were to merge and test hypotheses derived from both the primate morphological origins literature and the musical behavior origins …

Development of a CNG intensifier for high pressures
A CNG intensifier has been designed to compress natural gas from a variable, elevated-pressure storage source (20 - 200 bar) to a constant high discharge pressure (200 bar). The intensifier delivers variable amounts of gaseous fuel (5 - 43 kg/hr) at a maximum required pressure ratio of 10:1 for …
