We have measured lifetimes and deduced deformation parameters for rotational bands in 133Pm by the Doppler-shift attenuation method. A strongly coupled band based on the configuration with a hole in the g9/2 orbital has deformation parameter β2 = 0.40 (5), which is comparable to or larger than typical superdeformed bands in the A ∼130 region. We observe this band in 133Pm down to its I=K=9/2 bandh
High spin states in I113 were studied with the Ni58(58Ni, 3pγ) reaction at 240 MeV, using the eurogam array in Daresbury, United Kingdom, with 45 Ge detectors. A total of five deformed intruder bands extending to spins I ranging from (73/2-89/2)Latin small letter h with stroke have been identified, all of which reach frequencies Latin small letter h with strokeω>1.0 MeV and excitation energies ∼25
Coastal and marine environments attract hundreds of millions of tourists every year, and in regions including the Mediterranean or the Caribbean, tourism is a mainstay of the economy. Given that a considerable share of tourism is 'sun, sand, and sea' focused, the sector is dependent on the integrity of coastal resources such as unpolluted beaches and waters. These resources are increasingly threat
Three rotational bands in 108Sn have been investigated to high frequency via the 54Fe(58Ni,4p) reaction at 243 MeV. One of these bands is observed to undergo a band crossing at high spin. All three bands show a large decrease in their dynamic moments of inertia, to approximately one third of the rigid body value, as the rotational frequency approaches 1 MeV/. The structures of these bands are thou
Precise level lifetimes have been measured for various superdeformed bands in 148,149Gd and 152Dy with the Doppler-shift attenuation method. From the derived quadrupole moments, Q0, we find large differences in deformation between the yrast bands and some excited bands in the gadolinium isotopes. Moreover, two of the excited Gd bands and the 152Dy yrast band, which have identical moments of inerti
Six rotational bands built on superdeformed intrinsic configurations have been observed in the 149Gd nucleus with the Eurogam spectrometer. Orbital configuration assignments have been suggested on the basis of their effective alignments calculated with the Nilsson-Strutinsky cranking model. Most of the excited bands have identical partners in neighboring nuclei including one case differing by four
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.

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
