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...
plagiarism in esl/efl learning contexts has been established as a dynamic and multi-layered phenomenon and has become a topic engaging many researchers in a heated debate in recent years. comparisons of student-generated texts with their source texts have shown that students rely on source texts in their writings and copying is a major strategy used by both l1 and l2 writers. in our country a...
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...
The availability of iron for roots has been demonstrated as a critical factor in plant production. The addition of synthetic iron chelates to soil is a common practice in agriculture, which is not economically beneficial. Besides, chemical iron fertilizers cause many problems such as food contamination and environmental pollution. Development of natural Ferrioxamine B as an efficient and safe i...
