On Kranjsko polje in central Slovenia, carbonate conglomerates have been dated to several Pleistocene glacial phases by relative dating based on the morphostratigrafic mapping and borehole data, and by paleomagnetic and 10Be analyses. To define how the age of conglomerates determines the geomorphological characteristics of karst surface features, morphometrical and distributive spatial analyses...
This article lists a number of geological data on the conditions of formation of some major gold deposits in the conglomerates of the Earth's crust. We analyze the metallogenic, tectonic, stratigraphic and other factors controlling the formation of gold-bearing conglomerates in certain fields, such as the Witwatersrand (S. Africa) and Darwaz (Tajikistan). The following tectonic factors play the...
Focusing on economic distress episodes in an industry, we estimate the effect of conglomeration on resource allocation. Distressed segments have higher sales growth, higher cash flow, and higher expenditure on research and development than single-segment firms. This is especially true for segments with high past performance, for unrated firms, and in competitive industries. Single-segment firms...
Ratio blends of PLGA/PCL: (0:10), (1:9), (2:8), (3:7), (4:6), (5:5), (6:4), (7:3), (8:2), (9:1), and (10:0) were spin-coated to produce thin films; surface topographies were determined using interferometric microscopy. It was demonstrated that micro-wells of a defined size (150 mm) were present in all PCL dominant PLGA/PCL systems. Stratification of PLGA with PCL enabled the formation of that s...
A case of canaliculitis with obstruction of the lacrimal canaliculus and accumulation of conglomerates is described. Pityrosporum pachydermatis was cultured from the conglomerates. To the best of our knowledge this organism has not been previously implicated in such infections. Cure was obtained by treatment with nystatin administered topically and as an irrigation of the lacrimal pathways. The...
