Opis:: A careful analysis of the alleged electron paramagnetic resonance spectrum of VH$\text{}_{2}$ in silicon is made. The parameters of this spectrum coincide with those of the well-known excited state (S=1) spectrum of the oxygen vacancy defect. The conclusion is reached that they are one and the same.

Tytuł:: Dating littorina sea shore levels in Denmark on the basis of data from a mesolithic coastal settlement on skagens odde, northern Jutland

Opis:: The Mesolithic settlement site of Yderhede on Skagens Odde is interesting because it lies on Denmark’s highest Littorina coastline, 13 m above present-day sea level. The settlement was founded on peaty ground on the shore of a sheltered fjord. Pollen-analytical investigations have been carried out on marine/brackish gyttja deposits containing refuse from the settlement. These marine sediments were formed as a result of a transgression starting around 5300 cal. BC, reaching a maximum of 13 m above present sea level. Settlement took place during a subsequent regression and ceased in connection with a new Atlantic transgression. Subsequently, the lagoon silted up partly due to isostatic land upheaval of the area. The settlement lies on flat ground below the marked raised coastal cliff that runs from Frederikshavn to Hirtshals. The formation of this cliff has previously been assigned to the time of the Littorina Sea, but it is now suggested that it was formed in Late Glacial times. The two transgressions demonstrated here have been fitted into the overall pattern for sea-level change in Denmark. Subsequently, on the basis of well-dated sea-level curves for Southern Scandinavia, dates are given for the highest shore levels of the Littorina Sea. As a result of the interaction between increasing upheaval in a north-easterly direction and the general sea-level rise during the Littorina transgression, the maximum in the Gothenburg area (23 m isobase) occurs as early as 6300 cal. BC, whereas the maximum at the 0 m isobase in Southern Denmark first occurs around 3600 cal. BC.

Tytuł:: Lead times - their behavior and the impact on planning and control in supply chains
Autorzy:: Nielsen, P.
Michna, Z.
Sørensen, B. B.
Dung, N. D. A.
Powiązania:: https://bibliotekanauki.pl/articles/407076.pdf

Tematy:: supply chain management

Opis:: Lead times and their nature have received limited interest in literature despite their large impact on the performance and the management of supply chains. This paper presents a method and a case implementation of the same, to establish the behavior of real lead times in supply chains. The paper explores the behavior of lead times and illustrates how in one particular case they can and should be considered to be independent and identically distributed (i.i.d.). The conclusion is also that the stochastic nature of the lead times contributes more to lead time demand variance than demand variance.

Opis:: A beamline for macromolecular crystallography is under construction at the Swedish synchrotron light source MAX-lab at Lund University in a collaborative effort between Denmark and Sweden. Of the 7 mrad horizontal wiggler fan emitted from the new superconducting multipole wiggler, the central 2 mrad will be used and split in three parts. The central 1 mrad will be used for a tunable station optimised for multi-wavelength anomalous diffraction experiments and on each side of the central fan there will be two fixed wavelength stations using different energies of the same part of the beam. These in total five stations can be used simultaneously and independently for collecting diffraction data.
