the kashkan formation (paleocene to middle eocene), consists of conglomerate, sandstone, and siltstone in the zagros folded zone, southwest iran. type of the sedimentary facies, architectural elements and trace fossils show that kashkan deposits were formed in a low sinuosity braided stream system, with north to south flow direction. the formation displays coarsening-upward succession reflects ...
This paper analyzes the implications of diversification strategies and conglomerate mergers for the cost of capital in a model where the cost of capital depends on liquidity. We show that in a finitely liquid market with asymmetrically informed investors, both the benefits and the costs of diversification can be related to two characteristics of a firm’s investment opportunities. The benefits c...
This work reports the first example of the transformation of conglomerate (R)- and (S)-crystals into racemic crystals via sublimation. Crystallographic analysis of racemic isopropyl 3,3,3-trifluoro-2-hydroxypropanoate did not reveal the highly expected heterochiral dimer indicating that this compound is capable of forming exclusively homochiral oligomers via infinite multi-centred H-bonding net...
A straightforward unprecedented sublimation protocol that reveals both conversion of a racemic compound into a racemic conglomerate and subsequent enantioenrichment has been developed for the proteinogenic amino acid valine. The phenomenon has been observed in closed and open systems, providing insight into asymmetric amplification mechanisms under presumably prebiotic conditions.
Conglomerate reservoir is an important part of unconventional oil and gas resources, which has great developmental potential. However, its sedimentary environment structural background are complex, cementation types, gravel volume fraction shape quite different, leads to strong heterogeneity. When developing a conglomerate reservoir, it extremely difficult drill because It obtain the mechanical...
