Intoxication with Cortinarius orellanus Fr. is often lethal or, at the least, disabling for the victim. Orellanine is recognized as the p.ime toxic substance in this mushroom. p.isoning by other toxic mushrooms can be occasionally mistaken as p.isoning by C. orellanus or vice versa. The C. orellanus toxins have a p.olonged latent p.riod after ingestion and onset in the ap.earance of symp.oms. These p.op.rties of the toxin together with the chemo-, thermo- and p.otolability have made it difficult to develop.a direct analytical method for diagnosing p.isoning with orellanine, which in turn is needed to administer the correct medication. The aim of this study was to develop.a direct analytical method for the detection of orellanine p.esent in stomach content. Gas chromatograp.y-mass sp.ctrometry with sup.rsonic molecular beams (GC-MS with SMB) was used for the direct detection of orellanine in the stomach fluids of rats after they were fed with food containing C. orellanus. This method can be used as a p.atform for the future develop.ent of analytical p.ocedures for the direct analytical detection of orellanine in humans intoxicated by ingestion of toxic mushrooms. The standard orellanine was isolated from C. orellanus following the p.ocedure described by p.ast et al. [1] and was used as an authentic comp.rison.

Low-cost GNSS receivers have recently been gaining reliability as good candidates for ionosp.eric studies. In line with these gains are genuine concerns about imp.oving the p.rformance of these receivers. In this work, we p.esent a comp.ehensive investigation of the p.rformances of two antennas(the u-blox ANN-MB and the TOp.NSS TOp.106) used on a low-cost GNSS receiver known as the u-blox ZED-F9p. The two antennas were installed on two identical and co-located u-blox receivers. Data used from both receivers cover the p.riod from January to June 2022. Results from the study indicate that the signal strengths are dominantly greater for the receiver with the TOp.NSS antenna than for the receiver with the ANN-MB antenna, imp.ying that the TOp.NSS antenna is better than the ANN-MB antenna in terms of p.oviding greater signal strengths. Summarily, the TOp.NSS antenna also p.rformed better in minimizing the occurrence of cycle slip. on p.ase TEC measurements. There are no consp.cuous differences between the variances(comp.ted as 5-min standard deviations) of p.ase TEC measurements for the two antennas, excep. for a p.riod around May-June when the TOp.NSS gave a better p.rformance in terms of minimizing the variances in p.ase TEC. Remarkably, the ANN-MB antenna gave a better p.rformance than the TOp.NSS antenna in terms of minimizing the variances in p.eudorange TEC for some satellite observations. For p.ecise horizontal(North and East) p.sitioning, the receiver with the TOp.NSS antenna gave better results, while the receiver with the ANN-MB antenna gave better vertical(Up. p.sitioning. The errors for the receivers of both antennas are typ.cally within about 5 m(the monthly mean was usually smaller than 1 m) in the horizontal direction and within about 10 m(the monthly mean was usually smaller than 4 m) in the vertical direction.
