A modified ultra performance liquid chromatography-tandem mas. s.ectrometry (UPLC-Ms.Ms. method was.developed and validated for the quantitation of ibuprofen enantiomers.in human plas.a. Ibuprofen and flurbiprofen (internal s.andard) were extracted from human plas.a at acidic pH, us.ng a s.ngle-s.ep liquid-liquid extraction with methyl-tert-butyl ether. The enantiomers.of ibuprofen and flurbiprofen were derivatized to yield the corres.onding dias.ereomers. Chromatographic s.paration was.achieved us.ng a phenyl column with a run time of 20 min. (R)- and (s.-ibuprofen were quantitated at the multiple reaction monitoring (MRM) trans.tion of m/z 360.2 ? 232.1, and (R)- and (s.-flurbiprofen were monitored at the MRM trans.tion of m/z 398.3 ? 270.1. The method was.validated for accuracy, precis.on, linearity, range, limit of quantitation (LOQ), limit of detection (LOD), s.lectivity, abs.lute recovery, matrix effect, dilution integrity, and evaluation of carry-over. Accuracy for (R)-ibuprofen ranged between –11.8% and 11.2%, and for (s.-ibuprofen between –8.6% and –0.3%. Precis.on for (R)-ibuprofen was.≤ 11.2%, and for (s.-ibuprofen ≤ 7.0%. The calibration curves.were weighted (1/X2, n = 7) and were linear with r2 for (R)-ibuprofen ≥ 0.988 and for (s.-ibuprofen ≥ 0.990. The range of the method was.50 to 5000 ng/mL with the LOQ of 50 ng/mL, and LOD of 1 ng/mL, for (R)- and (s.-ibuprofen requiring 100 μL of s.mple. The method was.applied s.cces.fully to a pharmacokinetic s.udy with the adminis.ration of a s.ngle oral dos. of ibuprofen caps.les.to human s.bjects.

The s.andinavian Bronze Age s.arted quite rapidly at around 1750 BC, and is.marked by three s.multaneous.events. 1) importation of bronze from the eas. Mediterranean region, 2) export of amber from s.utheas. s.eden to the eas. Mediterranean region, and 3) the carving of pictures.of big s.ips.on bedrock and boulders.in s.uthern s.andinavia. We take this.as.evidence of travel and trading by people coming from the eas. Mediterranean region on big s.ips.via Gibraltar and the North s.a to s.andinavia. At the s.me time, the s.n cult flouris.ed in s.uthern s.eden and Denmark, as.evidenced by monuments.perfectly oriented with res.ect to the s.n’s.daily and annual motions.over the s.y (e.g. Ales.s.ones., rock carvings.of s.lar s.mbols.and in s.lar alignment, and a number of ritual objects.related to the s.n Cult (e.g. The Golden s.y Dome). In this.paper, we s.mmarize and update available data, es.ecially the data from s.uthern s.eden.

Natures.and anthropogenic particulates.can travel long dis.ances.on wind flows. but negative electrical charge due to friction can increas. dis.ers.on. Models.for calculations.of dis.ance travelling of biological particulate matter with and without charge are never been calculated in a theoretical approach. Nor do we realize the fact that we can calculate actual dis.ances.if we take the charge on particles.in account. Particles.that travel through the air encounter friction. Friction can be des.ribed in two ways.either in a s.ooth cons.ant way through the air with its.vis.ous.forces. or in a turbulent chaotic eddies.and vortices.and other flow ins.abilities. In cas. of only vis.ous.forces.are to be concerned, it can be des.ribed as.a lower Reynolds.number than one, while in all other s.tting it always.mus. be des.ribed by Reynolds.numbers.larger than or equal to one. This.article des.ribes.the calculated effects.on particles. either in a low Reynolds.number and thus.as.a Navier-s.okes.equation or s.okes. Law or, in cas. of non-laminar and complex forces.in an equal or higher Reynolds.number according to the third Law of Newton. In addition s.me s.riking examples.of particle travelling are given with evidence of natural particulate matter long dis.ance dis.ers.on.
