Causes of Magmatic Differentiation

Studies of Magmatic Systems

Notch inhibits osteoblast differentiation and causes osteopenia.

Notch receptors are determinants of cell fate decisions. To define the role of Notch in the adult skeleton, we created transgenic mice overexpressing the Notch intracellular domain (NICD) under the control of the type I collagen promoter. First-generation transgenics were small and osteopenic. Bone histomorphometry revealed that NICD caused a decrease in bone volume, secondary to a reduction in...

Magmatic Processes : Physicochemical Principles

The viscosities of eight melt compositions in the System albite-H20-F20_1 have been determined at high pressure and temperature. Measurements were performed using the falling sphere method at 1000-1600°C and 2.5 to 22.5 kbar. Fluorine and water strongly decrease the viscosity of albite melt at all pressures and temperatures investigated. The viscosity of a fluorine-bearing albitic melt decrease...

Magmatic ”Quantum-Like” Systems

Quantum computation has suggested, among others, the consideration of ”non-quantum” systems which in certain respects may behave ”quantum-like”. Here, what algebraically appears to be the most general possible known setup, namely, of magmas is used in order to construct ”quantum-like” systems. The resulting magmatic composition of systems has as a well known particular case the tensor products.

Electrocardiographic differentiation of the causes of left ventricular diastolic overload.

Left ventricular hypertrophy due to diastolic overload is characterized by the following in lead V6: (a) tall R wave; (b) prominent initial Q wave; (c) minimally elevated concave-upward ST segment; and (d) relatively tall symmetrical T wave. Reciprocal deep S waves are seen in lead V1. This study reflects a further evaluation of these parameters in the four main causes of left ventricular diast...
