This paper reports the results of non-destructive energy dispersive x-ray fluorescence (EDXRF) analysis 186 obsidian artifacts from eight archaeological sites attributable to Alföld Linear Pottery Culture (c. 5600-4900 cal BC). is largest instrument-based study yet conducted and reported for (ALPC) Slovakia, where ALPC chipped lithic assemblages are almost entirely composed items. Results show ...

we have refined the technique for isolating and propagating cultures of primary ovarian carcinosarcoma cells (oscs) derived from ascites, which allowed the cells to obtain the biphasic features of carcinosarcoma in cell culture conditions (presence of both carcinoma and mesenchymal morphologic types). this protocol involves a simple yet rapid method for the growth and propagation of ascites osc...

Microbial cells are producers of natural polymers present in plant cells. Production of pullulan (an extracellular microbial polysaccharide) by Aureobasidium pullularia pullulans (P. pullulans) was studied under fermentation conditions, and kinetic parameters were determined. Pullulan formation obeyed a growth and non-growth associated term. PHB (polyhydroxybutyrates) an intracellular biopo...
