Single particle signatures in high-spin, quasi continuum states in 193,194 Hg from g-factor measurements

The average g factors of high spin, high-excitation energy, quasi continuum structures in 194,193Hg were measured by observing the precessions of the angular distributions of γ-ray transitions in several normal-deformation bands that coalesce in the decay of the entry distribution of states. The average g factors of the states leading to the three main bands in the 193,194Hg isoles were: 〈g(193Hg)〉 = +0.19(1) and 〈g(194Hg)〉 = +0.26(1), respectively. These average g factors are smaller than the average of the g factors of the high energy states in the three superdeformed bands of 194Hg, 〈g(SD;194Hg)〉 = +0.41(8). While the nucleus in the superdeformed well behaves like a rigid rotor, the present results demonstrate the important role played by multiple, quasi particle neutron configurations in the structure of normal-deformation, highly-excited nuclear states

First direct measurements of g factors of the three superdeformed bands of 194Hg

The average g factors of the high-energy states of the three superdeformed bands in 194Hg were determined directly in a transient field experiment. The reaction 150Nd(48Ca,4n)194Hg at a beam energy of 203 MeV was used to provide recoiling reaction product nuclei with sufficient velocity to traverse a gadolinium ferromagnetic layer. The resulting g factors g(SD1)50.36(10), g(SD2)50.41(20), and g(SD3)50.71(26) are in agreement with cranked Hartree-Fock calculations as well as with the picture of a rigid rotation for which g 5Z/A

Development and Testing of a Question Prompt List for Common Hand Conditions: An Exploratory Sequential Mixed-Methods Study

PurposeA question prompt list (QPL) is a tool that lists possible questions a patient may want to ask their surgeon. Its purpose is to improve patient-physician communication and increase patient engagement. Although QPLs have been developed in other specialties, one does not exist for hand conditions. We sought to develop a QPL for use in the hand surgery clinic using a mixed-methods design.MethodsWe drafted a QPL based on prior work outside of hand surgery and then used an exploratory sequential mixed-methods design (both qualitative and quantitative methods) to finalize the QPL. Qualitative evaluation included both a written questionnaire completed by a patient advisory board, hand therapists, and hand surgeons, as well as cognitive interviews conducted with clinic patients using the tool. Revisions to the QPL were made after each phase of qualitative analysis. The final QPL was then evaluated quantitatively using the system usability score (SUS) questionnaire to assess its usability.ResultsA patient advisory board consisting of 6 patients, 5 hand therapists, and 6 hand surgeons completed the written questionnaire. Thirteen patients completed a cognitive interview of the QPL. We completed a content analysis of the qualitative data and incorporated the findings into the QPL. Twenty patients then reviewed the final QPL pamphlet and completed the SUS questionnaire. The resulting SUS score of 78.8 indicated above-average usability of the QPL tool.ConclusionsThe QPL developed in this study, from the perspective of multiple stakeholders, provides a usable tool to engage and prompt patients in asking questions during their visit with their hand surgeon with the potential to improve communication and patient-centered care.Clinical relevanceThis study provides clinicians with a QPL developed for use in the hand surgery clinic setting, aimed at facilitating more thorough patient-provider discussion

Signature of the shape coexistence in \u3csup\u3e72\u3c/sup\u3eKr: discontinuities of the moment of inertia at low spin

The low-lying level structure of the N=Z nucleus 72Kr was studied by 40Ca(35Cl, p, 2nγ)72Kr at 95 MeV. Gamma ray coincidences are used to construct for the first time a level scheme for this nucleus based on coincidence gating with the previously identified 2+-0+ transition. The new level scheme indicates strong prolate-oblate mixing of two shape coexisting bands. The results support theoretical predictions of a stable oblate minimum in this region. © 1990

Identification of transitions in \u3csup\u3e73\u3c/sup\u3eKr and the search for large oblate deformation

The gamma transitions in 73Kr have been identified for the first time by tagging the gamma rays with reaction products of mass 73 and neutrons produced in the reaction 40Ca (95 MeV 35Cl, pn) 73Kr. A gamma-gamma coincidence experiment was performed at Oak Ridge with a Compton suppressor array which utilises 20 Ge detectors equipped with Compton suppressors. Transitions in 73Kr have been placed into two bands. Several other transitions also are identified in 73Kr but not placed into the level scheme

Wound monitoring of pH and oxygen in patients after radiation therapy

Objectives Postradiogenic wound healing disorders are an important clinical problem. While a variety of treatment modalities are available, there is no strategy to objectively judge treatment success. The aim of this study was to evaluate a 2D luminescence imaging system for pH and oxygen in non-healing wounds after radiotherapy. Methods Luminescence 2D imaging was performed with the VisiSens (Presens, Regensburg, Germany) 2D imaging systems A1 and A2 for oxygen and pH, respectively. Biocompatible planar luminescent sensor foils were applied to non-irradiated and irradiated skin as well as to radiogenic wounds of five patients and the pH and the oxygen saturation was determined. Results pH measurements showed significant differences between non-irradiated skin (6.46 +/- 0.18) and irradiated skin (6.96 +/- 0.26). Radiogenic wounds exhibited the highest pH values (7.53 +/- 0.26). Oxygen measurements revealed a mean oxygen saturation of non-irradiated skin of 6.19 +/- 0.83 mmHg. The highest value of oxygen saturation (28.4 +/- 2.4 mmHg) was found on irradiated skin while irradiated wounds had a poor oxygen saturation (9.4 +/- 2.2 mmHg) (mean +/- s.e.m.). Conclusion We found that routine measurement of pH and pO2 in patients could be easily integrated into the clinical routine. The results of the measurements show unfavorable pH and oxygen saturation conditions for wound healing in irradiated wounds. Interestingly, irradiated wounds exhibit a more pronounced hypoxia than irradiated skin which is reflected by an altered pH and pO2 compared to unirradiated skin, which has the potential to serve as a prognostic marker in the future. In addition to the objectification of the treatment success of postradiogenic wound healing disorders, the extent of skin toxicity could already be predicted during radiotherapy with this method
