Global Navigation Satellite System (GNSS) signal quality, type of receiver equipment, and external environment can cause GNSS observations to be anomalous, these anomalies are sometimes reflected in pseudorange rather than phase observations. To better detect blunders observations, this paper proposes three blunder detection methods under the same frequency different code types (case1), frequen...

In the paper a new approach to data representation and manipulation is described, which is called the concept-oriented data model (CODM). It is supposed that items represent data units, which are stored in concepts. A concept is a combination of superconcepts, which determine the concept's dimensionality or properties. An item is a combination of superitems taken by one from all the superconcep...

Simultaneous formaldehyde biodegradation, urea hydrolysis and denitrification in anoxic batch assays and in a continuous laboratory anoxic reactor were investigated. In batch assays, the initial formaldehyde biodegradation rate was around 0.7 g CH(2)Og VSS(-1)d(-1) and independent of the urea concentration (90- 370 mg N-NH(2)CONH(2)l(-1)). Urea was completely hydrolyzed to ammonium in the prese...

Persian poppy (Papaver bracteatum Lindl.) is a perennial medicinal plant belonging to the Papaveraceae family that endemic mountainous areas in Northern Iran. It known for high amounts of valuable benzylisoquinoline alkaloid thebaine. The effects induced polyploidy as well effect methyl Jasmonate (MeJA) elicitation on root production thebaine and expression five biosynthesis related genes were ...

objective(s): the aim of this study was to investigate the methylation status and mrna expression levels of p15, death-associated protein kinase (dapk), and suppressor of cytokine signaling-1 (socs1) genes in multiple myeloma (mm). materials and methods: the bone marrow samples of 54 mm patients were collected and the methylation status of the p15, dapk, and socs1 gene promoter regions was dete...

conclusions some results of the correlation coefficients are not the same with visualization. the reason may be due to the small number of data. materials and methods in the foundation-application study, we constructed two-way gene networks using nonparametric methods, such as spearman’s rank correlation coefficient and blomqvist’s measure, and compared them with pearson’s correlation coefficie...
