Numerical modeling of the carbonate and the sandstone formations
It is of interest in various scientific and industrial contexts to make a reliable estimation of the transport properties of porous media via more accessible probes such as NMR that yield information on static pore geometry and porosity. When the pore geometry is simple, there are empirical recipes that have long proven reliable in bridging the gap. For heterogeneous systems, such recipes fail ...
متن کاملFluvial Facies and Provenance of the Early Permian Warchha Sandstone Salt Range, Pakistan
Deposits of the Warchha Sandstone in the Salt Range, Pakistan are characterised by a range of fluvial facies and architectural elements that together preserve a record of both the proximal and distal parts of a meandering river system that drained the northern margin of Gondwanaland. Several fining-upward cycles are recognised and completely preserved cycles can be divided in to three parts; a ...
متن کاملThe so-called Stabilizer Theorem
Theorem 1.1 (Hrushovski’s Theorem 3.5). Let G be a definable group, X a definable subset, and G̃ be the ∨-definable group generated by X. Suppose all this data is defined over a model M . Suppose μ is an M-invariant translation-invariant ideal on subsets of G̃. Let q be a wide type over M , contained in G̃. Identify q with its ∧-definable set of realizations. Suppose (F) there exist two realizatio...
متن کاملOn the Structure of the so Called 5-methyl Glucose of Ohle and Von Vargha
In continuation of the work on the nature of the glycoside formation in the partially substituted sugars,’ a study of the 5methyl glucose described by Ohle and von Vargha2 was undertaken by us. On the basis of previous experience, a substance of this structure was expected to form but one glucoside, the furanoside, and it was therefore surprising to find indication of the formation of two gluco...
متن کاملA New Look at the So-Called Trammel of Archimedes
1. INTRODUCTION. STANDARD TRAMMEL. Figure 1a shows a line segment of fixed length whose ends slide along two perpendicular axes. It can be realized physically as a sliding ladder or as a sliding door moving with its ends on two perpendicular tracks. During the motion, a fixed point on the segment traces an ellipse with one quarter of the ellipse in each quadrant (Figure 1b), so this device is c...
