Crystallisation kinetics
D. Quigley (Theory Group) The rates at which crystals nucleate and grow from either a supercooled melt, or a supersaturated solution, are essential inputs for solidification models in a variety of contexts. These include materials synthesis and processing, development of antifreeze strategies for cryopreservation, and understanding the formation of harmful biological crystals such as kidney st...
متن کاملGrowth Rate Kinetics for Struvite Crystallisation
The crystallisation of struvite is one means of removing phosphate (and nitrogen) from nutrient-rich wastewater. As with all crystallisation processes, the growth rate of the crystals and its dependence on supersaturation is of considerable interest in designing processing equipment. Modelling of struvite solubility using the computer package MINTEQA2 showed that struvite exhibits a minimum sol...
متن کاملBone mineral densities in normal Bangladeshi women
fracture. Several chronic medical conditions, medications, and life style factors affect bone mineral accrual. This study aims to evaluate the bone mineral densities and hip axis lengths in the local population. Materials and Methods: 336 normal Bangladeshi women age ranges 20 to 70 years had evaluation of their bone mineral densities (BMDs) by means of dual X-ray absorptiometry (DXA). Results:...
متن کاملBone Mineral Quality
The main function of bone is to promote locomotion and protection of vital organs. Bone is also an important mineral ions reservoir, essential to maintain phosphocalcic homeostasis. Bone mineral is a calcium phosphate named “apatite”, which form naturally in the Earth’s crust (Wopenka & Pasteris 2005). Compared to others minerals, apatite is more “tolerant” and is very accommodating to chemical...
متن کاملAbnormal Bone Mineral Maturation
chronically uremic but nonacidotic rats with normocalcemia and hyperphosphatemia revealed smaller apatite crystals and an increase in the X-ray amorphous mineral fraction when compared to age-matched, pair-fed control animals, indicating less advanced mineral maturation in the uremic animals. Studies in animals with varied degrees of chronic renal insufficiency revealed a progression of the bon...
