The Linear Growth Rates of Pentaerythritol Crystals
The linear growth rates of the (101) faces of single crystals of Pentaerythritol (Pe) in aqueous solutions have been measured as a function of temperature (10-50°C), and concentration difference (0.25 x 10° acs 2.60 x 10-2 KgPe/Kg Solution) under stagnant conditions in a batch cell. The effect on …

Strongly Asymptotically Optimal Methods for the Pathwise Global Approximation of Stochastic Differential Equations with Coefficients of Super-linear Growth
Our subject of study is strong approximation of stochastic differential equations (SDEs) with respect to the supremum and the L_p error criteria, and we seek approximations that are strongly asymptotically optimal in specific classes of approximations. For the supremum error, we prove strong …

Experimental Sensitivity Analysis and Control of Thermoacoustic Systems in the Linear Regime
… The primary aim of designers is to design linearly stable thermoacoustic systems in which these dangerous oscillations do not arise. In thermoacoustics, adjoint-based sensitivity analysis has shown promise at predicting the parameters which have the most influence on the linear growth and …

Early childhood diarrhea and growth among HIV-exposed, uninfected infants in Kenya
Background: Diarrhea and poor linear growth are leading causes of childhood morbidity and mortality in low- and middle- income countries. While global childhood mortality has been significantly reduced in the past decades, further reductions will likely require a better understanding of the causes …

The Effect of Anomalous Resistivity on the Electrothermal Instability
… Z-pinch-like high energy density platforms. ETI growth for high-mass density materials is predominantly striation form which corresponds to magnetically perpendicular mode growth. The striation form is caused by a resistivity that increases with temperature, which is often the case for high-mass …

Some Studies on the Competitive Colonisation of Cellulosic Substrates by Microorganisms
… commonly occurring cellulolytic fungi for high linear growth rate and cellulolytic ability, eight fungi were selected for further studies. An assessment of the optimum pHs and temperatures for linear growth showed how particular fungi may be encouraged to dominate the colonisation of straw by …

Type 1 diabetes in children - risk factors and prediction.
… (T1D). Increased birth weight (BW), increased linear growth and gestational infections are among the reported risk factors. T1D is predictable by analysis of HLA genotypes and islet cell autoantibodies. In this thesis risk factors and prediction of T1D were studied as part of the Diabetes …

Adaptive control of nonlinear systems
In the last few years, adaptive control of nonlinear systems has emerged as an important area of research, with possible applications in areas as diverse as robotic systems, electric motors, chemical processes, and automotive suspensions. Many of the existing results employ design methods and proof …

Closing the memory gap in stochastic functional differential equations
… equations (SFDEs) whose coefficients have linear growth. In mathematical finance, an option pricing formula with full finite memory is obtained through convergence of stock dynamics with memory gap to stock dynamics with full finite memory.

An Ecogeographic Study of Body Proportion Development in the Sadlermiut Inuit of Southampton Island, Nunavut
This thesis explores growth status and body proportion development in past North American Arctic populations. Living in one of the most extreme environments on the planet, Arctic foragers provide an opportunity to explore how human morphological variation is shaped by growth and climate. The study …

REGULATORY PROCESSES IN ULTRA SLOW GROWING MICROORGANISMS (ESCHERICHIA COLI, BACILLUS POLYMYXA)
<p>In a continuous fermentor with 100% recycle, growth of Escherichia coli and Bacillus polymyxa occurs in three sharply distinct phases: an initial phase of exponential growth that terminates when the glucose level in the fermentor falls below transport saturation levels; a second phase of linear …

Enhancing CO2 mass transfer in large scale algal raceway ponds through wave generation
The commercial growth of algae in raceway ponds is limited by the availability of carbon, supplied as carbon dioxide (CO2), resulting in a linear growth rate, also described as biomass productivity, determined by the mass transfer rate. This reduces the specific growth rate of the system, as the …
