This paper deals with the physical traces of Sámi past in southern and central Sweden. From the Norse sagas, and from archaeological sources, there is a manifold of evidence of Sámi–Norse interaction and of Sámi presence, and habitation in central and southern Scandinavia from the Late Iron Age to the Middle Ages. From the early modern period there are diverse written sources addressing Sámi habit
In Sweden, industrial archaeology has been of limited distention and has played a modest role. Instead the disciplines of ethnology, history and art history has been dominating studies concerning industrial material heritage. Archaeological studies of metal production have been widely successful, but the focus has been set on early metal making rather than studies of industrialization, industriali
Objective To characterize the redistribution patterns of zinc and calcium ions during human sperm capacitation and to investigate their roles in sperm maturation and fertilization. Design In vitro experimental study using synchrotron-based x-ray fluorescence microscopy and complementary immunohistochemistry to assess elemental changes during different capacitation stages at nanometric spatial reso
BACKGROUND: The period immediately following psychiatric inpatient care is recognized as a time of elevated risk of suicide, yet little is known about factors that influence how soon suicide occurs after discharge.AIM: To examine the timing of suicide among persons after psychiatric discharge and identify sociodemographic and clinical factors associated with a shorter time to death by suicide.METH
En stad är inte endast en fysisk bild av dess gator och hus. Vi människor har också en egen relation till en stad, ett slags djupare existentiellt förhållande. Därför finns heller inte en berättelse om staden, utan flera - samtida - och ofta djupt personliga.
2023 JCP Emerging Investigators Special Collection: Tuning perovskite nanocrystal superlattices for superradiance in the presence of disorder
Semi-decoupled bands based on the πh9/2 ⊗ vi13/2 configuration are observed in 162Tm,164Tm and 174Ta. Spins assigned to these bands imply an inversion of the expected signature splitting, which is interpreted as being the result of a residual proton-neutron interaction.
Four new superdeformed (SD) bands have been observed in 147Gd using the EUROGAM II spectrometer. By comparison with 146,148,149Gd SD bands, we use the effective alignment to assign excited band configurations, with the support of the Nilsson-Strutinsky cranking formalism. The effect of the crossing of the [642]5/2 and [651]1/2 neutron orbitals lying just below the magic N= 86 SD shell gap has been
Intruder rotational bands have been investigated to high frequency in 10951Sb. Five decoupled (ΔI=2) bands extending to rotational frequencies above 1.4 MeV/ℏ have been observed. At the highest frequencies, the script J sign(2) dynamic moments of inertia for four of these bands are seen to decrease steadily to unexpectedly low values, script J sign(2) ∼ 10 ℏ2 MeV-1. These four bands, which are int
This is a paper about gymnastics and a primordial form of geological knowledge. It pursues an interpretation of gymnastics, broadly defined, as a philosophy that interrogates what the Earth is. The goal is to reconstruct the epistemic implications of gymnastic practice in order to understand the evolution of animal motility as a prototypical form of geological knowledge. Since gravity is a global
High efficiency, low total harmonic distortion (THD), and near-unity power factor are essential for low voltage battery charging systems to satisfy modern power quality requirements. In this study, an isolated totem-pole power factor correction (PFC) integrated buck converter has been designed and analyzed for low-voltage battery charging applications. The proposed topology combines a bridgeless t
Lifetimes of states in two rotational bands in 108Sn and one in 109Sb have been determined using the Doppler shift attenuation method. The deduced quadrupole moments for the states are in excellent agreement with cranked Nilsson model predictions, which imply a gradual change in the nuclear shape from collective near-prolate at medium spin to noncollective oblate at high spin. This change results
High-spin states in the odd-[Formula Presented] nucleus have been investigated with the [Formula Presented] reaction at 94 MeV using the Chalk River [Formula Presented] array. Three decoupled [Formula Presented] rotational bands extending to spins [Formula Presented] in the range [Formula Presented] have been identified and connected to known low-lying states. Experimental observations for the mos
The level structure of 102Pd has been investigated using data collected with the Eurogam 2 array. Several cascades of γ-rays have been established up to high spins. Termination of rotational bands has been observed at Iπ = 28 - and 32 +, and tentatively at Iπ = 38+ and 42+. The nucleus 102Pd is the first case where rotational bands built on valence space configurations are followed from spin close
High-spin states in the nucleus [Formula Presented]Te have been studied with the reaction [Formula Presented]Ni[Formula Presented]Fe,[Formula Presented] at 236 MeV using an early implementation of the Gammasphere array. Three rotational bands extending to spins [Formula Presented] and excitation energies [Formula Presented] MeV have been identified and connected to known low-lying states. In the m
The level structure of 102Rh has been investigated using the EUROGAM Phase2 array. Bands observed up to high spins are discussed in terms of band terminations. 102Rh is the first doubly odd nucleus below Z = 50 in which band terminations are established.
The highest-spin discrete states (I ∼ 60 ℏ and Ex ∼ 30 MeV) in normal deformed nuclei have been observed in the rare-earth isotope 156Dy using the 124Sn(36S,4n) reaction in conjunction with the GAMMASPHERE spectrometer. The positive parity yrast sequence appears to evolve smoothly from a prolate (collective) towards an oblate (non-collective) shape, in contrast to the sudden shape change observed
Four new superdeformed bands have been found in the nucleus 86Zr. The good agreement between experiment and configuration-dependent shell correction calculations suggests that three of the bands have triaxial superdeformed shapes. Such unique features in mass A ∼ 80 superdeformed bands have been predicted, but not observed experimentally until now. A fourth band in 86Zr is interesting due to a fai
Excited states in [Formula Presented] have been observed with the Stony Brook array of six Compton-suppressed HPGe detectors and the [Formula Presented] reaction at 60 MeV using a thick target. New excited states which decay solely towards the [Formula Presented] ns, [Formula Presented] isomer have been identified using time-correlated spectroscopy. The previously known level scheme has also been
Six rotational bands in the odd-odd nucleus 174Ta have been populated with the 160Gd(19F,5n) reaction. High-spin states were identified using the NORDBALL array. Both signatures of the doubly decoupled π1/2- [541 ] ⊗ v1/2- [521] band and semi-decoupled π1/2- [541] ⊗ v7/2+ [633] band are observed, in addition to the high-K couplings of the π9/2- [514] ⊗ v7/2+ [633], π9/2- [514] ⊗ v5/2- [512], π7/2+
