När tystnad binder - En analys av passivitetsverkningar i svensk avtalsrätt

Utgångspunkten i svensk avtalsrätt är att rättsverkningar förutsätter aktiva handlingar. Avtal anses normalt uppkomma genom ett utbyte av samstämmiga viljeförklaringar i form av anbud och accept. Passivitet, dvs. underlåtenhet att handla, leder som huvudregel inte till avtalsbundenhet. Denna ordning vilar på avtalsfriheten och viljeprincipen, enligt vilken en part endast blir bunden till vad denneThe starting point in Swedish contract law is that legal effects require active actions. Contracts are normally considered to arise through an exchange of mutual declarations of intent in the form of an offer and acceptance. Passivity, i.e. failure to act, does not, as a general rule, lead to contractual obligations. This arrangement is based on freedom of contract and the principle of intent, acc

Band crossings and band terminations in rapidly rotating nuclei

Predictions on terminating configurations in nuclei with 10-12 valence particles outside the 146Gd core are compared with recent experimental data. Observed and calculated spectra show a remarkable similarity, at least for 158Er and 156Er which nuclei are discussed in detail here.

Crossings between unpaired rotational bands at I ≈ 30 in the N ≈ 90 region

It is shown that the band crossings observed at frequencies ≈h{stroke};hω ≈ 0.5 MeV can be qualitatively explained from Nilsson-Strutinsky calculations with no pairing correlations. The crossing bands are characterized by a different number of protons in h 11 2 orbitals leading to different deformationtrajectories in the (∋, γ)-plane. Above the band crossings, the calculated transition energies co

Coexistence between terminating and more collective configurations at very high spin in 155Dy

A comparison between the observed spectrum of 155Dy and calculations suggests that the yrast states in the I+30-40 region are built from bands whose deformation smoothly changes towards oblate shape (γ=60°) with band terminations in the I=45-50 region. The presence of other bands which show no terminating features is also naturally understood within the same theoretical framework.

Deformation in odd-mass nuclei near A ∼ 100 : one- and three-quasiparticle nilsson states in 9939Y60

The deexcitation of the 8.6 μs isomer of 9939Y has been studied using γ-ray spectroscopy techniques at LOHENGRIN and JOSEF. The resultant level scheme is analyzed within the ' framework of the particle-rotor coupling model. The ground-state band, to spin 19 2u+, is found to have band properties consistent with a π[422 5 2] Nilsson assignment. The 8.6 μs isomer and a side band with a band-head half

Evolution of Indigenous Peoples’ Rights as Human Rights : Contribution of Sámi Rights Cases at UN Human Rights Treaty Bodies

Over four decades, Indigenous Sámi individuals and communities have submitted to United Nations human rights treaty bodies, including the Human Rights Committee, several complaints in respect of the three Nordic countries Finland, Norway, and Sweden. Many of these Sámi rights cases have made important contributions to the understanding and application of Indigenous peoples’ rights globally, in add

Collective structures and smooth band termination in 109Sn

Six rotational bands up to energies Ex = 24.7 MeV and spins Jπ=(79/2−) have been identified in 109Sn using the GAMMASPHERE γ-detector array. Four of the bands show smoothly decreasing dynamic moments of inertia at rotational frequencies ℏω > 0.6 MeV. The bands arise at medium spins from a coupling of a valence d5/2, g7/2 or h11/2 neutron to the deformed 2p2h proton excitation of the Z=50 core 108S

High-spin states and rotational coexistence in 25Mg

New high spin states in 25Mg have been located above the neutron threshold using the 12C(14N, pγ)25Mg reaction at E=23.5 MeV. The members of the ground state rotational band (Kπ= 5 2+ have been tentatively identified up to 15 2+. The yrast 15 2+ (not a member of the ground state band) and 17 2+ states have also been tentatively assigned. These results support the interpretation of the new 17 2+ st

Properties of terminating bands in nuclei

General properties of terminating bands are briefly reviewed and exemplified on the observed high-spin properties ofl58Er andl56Er. The very similar features of the positive parity high-spin spectra of the N = 88 isotones of Dy, Er and Yb are pointed out and discussed. The possibility to estimate £(E2)-values in terminating bands from measured feeding times is explored. The spin contribution from

Description of nuclear moments and nuclear spectra in the particle-rotor model

The particle-rotor model using strong coupling basis functions is briefly reviewed. Recent developments are discussed. For example, a formalism for odd-odd nuclei (and negative parity states in even nuclei) is presented. With a standard neutron-proton interaction, measured spins and moments of transitional and deformed Ho nuclei are used to extract their main configurations. Total energy calculati

Gamma decay of high spin states in Mg25 above 6.1 MeV

New high spin states in Mg25 (up to 13.3 MeV in excitation) have been located using the N12,p)25Mg reaction at a laboratory beam energy of 23.5 MeV. Gamma decay from 28 neutron unbound levels has been observed (24 of which are reported here for the first time) up to 7 MeV above the neutron drip line. Tentative identification of the yrast line up to (17/2+ has been made, along with an extension of

Discrete levels in 154Dy above spin 30ħ : Evidence for terminating band structures

High-spin states in 154Dy have been studied using the TESSA2 γ-rays spectrometer following the 110Pd(48Ca,4n)154Dy reaction at a beam energy of 210 MeV. States up to 44+ and 37- have been observed. Below spin 30 the data display regular rotational behaviour which can be interpreted in terms of the cranked shell model. Above spin 30, sequences of levels connected by stretched E2 transitions, which

Precision oncology to overcome resistance in R/R AML in children and adults requires combinations of cytotoxic, targeted, and immunological treatments

Although outcomes for newly diagnosed acute myeloid leukaemia (AML) have been incrementally improved over the last decades, management of relapsed and refractory (R/R) AML remains a medical challenge. A curative intent for R/R AML usually involves chemotherapy (with or without targeted therapy) with subsequent consolidation, including allogeneic haematopoietic stem cell transplantation. Despite th

Rotational bands and particle-hole excitations at very high spin

A method of calculating high-spin states of nuclei within the cranked Nilsson-Strutinsky framework is presented and discussed in some detail. With this method, various high-spin features of nuclei are studied, such as shape coexistence, shape changes, band crossings and band terminations. Nuclei with different mass numbers such as 106Pd, 118Te, 158Yb and 187Au are used to exemplify the formalism.

A Writing State of Being

How do you write a fiction text that relates to entrepreneurship without rewarding entrepreneurship, successful innovations, or a commercial market? That was my initial question when I set out to write a short story with entrepreneurship in focus. In this metatext, I reflect on altruistic entrepreneurship and the writing process for writing the short story that emerged in relation to the research
