Mechanisms of Stone Formation [PDF]

Clinical Reviews in Bone and Mineral Metabolism, 2011
We have reviewed the general mechanisms involved in kidney stone formation, with reference to those composed of calcium oxalate or phosphate, uric acid, and cystine. These processes include nucleation of individual crystals, aggregation or secondary nucleation to produce small intrarenal multicrystalline aggregates, fixation within the kidney, and ...

Noise-Driven Mechanism for Pattern Formation [PDF]

, 2002
We extend the mechanism for noise-induced phase transitions proposed by Ibanes et al. [Phys. Rev. Lett. 87, 020601-1 (2001)] to pattern formation phenomena. In contrast with known mechanisms for pure noise-induced pattern formation, this mechanism is not

Formation of Kuiper Belt Binaries [PDF]

, 2007
The discovery that a substantial fraction of Kuiper Belt objects (KBOs) exists in binaries with wide separations and roughly equal masses, has motivated a variety of new theories explaining their formation. Goldreich et al.

Novel Approach to Prepare Magnesium and Mg-Al Alloy from Magnesia by Using the Closed Microwave Aluminothermic Method

Metals, 2023
Herein, we report a novel approach to obtaining magnesium and nanocrystal Mg-Al alloy from magnesia using a closed microwave aluminothermic method in order to solve the problems of high energy consumption, high pollution, and low productivity in the ...

Mechanism of Osazone Formation [PDF]

Nature, 1955
A FACT which seems to have escaped attention in formulating a mechanism for osazone formation is that β-alkayl substituted phenylhydrazines are oxidized very readily in air to form phenylhydrazones1:

Formation mechanisms and distribution of weathered volcanic reservoirs: A case study of the carboniferous volcanic rocks in Northwest Junggar Basin, China

Energy Science & Engineering, 2020
In view of the complex reservoir heterogeneities within weathered volcanic rocks, taking the Carboniferous volcanic weathered profile reservoir of the northwest Junggar Basin as an example, this study aims to characterize weathered volcanic rocks by the ...

Review on identification and prevention and control technology of spontaneous combustion risk area in goaf

Meikuang Anquan, 2023
The spontaneous combustion of residual coal in goaf has always been the focus of coal mine fire prevention and control work. Mastering the distribution law of coal spontaneous combustion risk area is the key to take prevention and control measures. Based

Mechanics of Rouleau formation

Biophysical Journal, 1981
The formation of rouleau of red blood cells is considered from the standpoint of adhesion theory. With the use of the elastic properties of the red blood cell membrane obtained from previous work, the strain energy of the red blood cell in rouleau formation has been computed. The surface energy of adhesion for the bonding of two red blood cells is then

The mechanism of porosity formation during solvent-mediated phase transformations [PDF]

, 2010
Solvent-mediated solid-solid phase transformations often result in the formation of a porous medium, which may be stable on long time scales or undergo ripening and consolidation.
