Demography and heat stress: the role of population dynamics in climate risk projections

The impact of climate change on human health is not distributed evenly with some demographic groups e.g. older adults, people with a low socio-economic status, city inhabitants being more susceptible to increasing temperatures. High-resolution spatial projections of population vulnerability are however scarce. Using Bayesian Model Averaging (BMA), this paper downscales population structure to intra-urban level for the case study of Madrid. First, empirical data from the municipal register of inhabitants are used to map where vulnerable groups reside. Demographic heterogeneity is captured through disaggregating the input data by age groups (below and above 65 years), sex and educational attainment (as a proxy for socio-economic status). Second, BMA is employed to project shares of these groups to 2050, under selected Shared Socioeconomic Pathways. The resulting distributions of population groups and their projected changes are relevant for local decision-making regarding adaptation strategies to decrease the health burden heat stress might impose in the future

Surgical management of exudative pericarditis after open heart surgery

IMSP Spitalul Clinic RepublicanArticolul este dedicat problemelor de diagnostic şi tratament chirurgical al pericarditei exudative postoperatorii. Patogenia și evoluția postoperatorie a pacienților cu acumulări de lichid în pericard a fost analizată prin prizma prezenței bolilor concomitente, duratei circulației extracorporale, terapiei cu anticoagulante şi antiinflamatorii nesteroide, analizei bacteriologice a lichidului. A fost propus un management terapeutic în rezolvarea pericarditelor exudative după operaţiile pe cord deschis.The article is dedicated to postoperative exudative pericarditis, the diagnostic and surgical treatment problems. The postoperative evolution of the patients with accumulation of liquid in pericardium was analyzed through the presence of consequent pathologies, extracorporeal circulation duration, anticoagulant and anti-inflammatory therapy, bacteriologic analysis of the liquid. We proposed a therapeutic ma nagement of exudative pericarditis treatment after open heart operations

In-beam fast-timing measurements in 103,105,107Cd

Fast-timing measurements were performed recently in the region of the medium-mass 103,105,107Cd isotopes, produced in fusion evaporation reactions. Emitted gamma-rays were detected by eight HPGe and five LaBr3:Ce detectors working in coincidence. Results on new and re-evaluated half-lives are discussed within a systematic of transition rates. The $7/2_1^+$ states in 103,105,107Cd are interpreted as arising from a single-particle excitation. The half-life analysis of the $11/2_1^-$ states in 103,105,107Cd shows no change in the single-particle transition strength as a function of the neutron number

Fast-timing measurements in 95,96Mo

Half-lives of the 19/2+ and 21/2+ states in 95Mo and of the 8+ and 10+ states in 96Mo were measured. Matrix elements for yrast transitions in 95Mo and 96Mo are discussed.Comment: Proceedings of XIX International School on Nuclear Physics, Neutron Physics and Applications, Varna, Bulgaria, 2011, 5 pages, 6 figure

Unexpected high-energy γ emission from decaying exotic nuclei

Abstract The N = 52 Ga 83 β decay was studied at ALTO. The radioactive 83Ga beam was produced through the ISOL photofission technique and collected on a movable tape for the measurement of γ-ray emission following β decay. While β-delayed neutron emission has been measured to be 56–85% of the decay path, in this experiment an unexpected high-energy 5–9 MeV γ-ray yield of 16(4)% was observed, coming from states several MeVs above the neutron separation threshold. This result is compared with cutting-edge QRPA calculations, which show that when neutrons deeply bound in the core of the nucleus decay into protons via a Gamow–Teller transition, they give rise to a dipolar oscillation of nuclear matter in the nucleus. This leads to large electromagnetic transition probabilities which can compete with neutron emission, thus affecting the β-decay path. This process is enhanced by an excess of neutrons on the nuclear surface and may thus be a common feature for very neutron-rich isotopes, challenging the present understanding of decay properties of exotic nuclei

Beta-delayed proton emission from 20Mg

Beta-delayed proton emission from 20 Mg has been measured at ISOLDE, CERN, with the ISOLDE Decay Station (IDS) setup including both charged-particle and gamma-ray detection capabilities. A total of 27 delayed proton branches were measured including seven so far unobserved. An updated decay scheme, including three new resonances above the proton separation energy in 20 Na and more precise resonance energies, is presented. Beta-decay feeding to two resonances above the Isobaric Analogue State (IAS) in 20 Na is observed. This may allow studies of the 4032.9(2.4)keV resonance in 19 Ne through the beta decay of 20 Mg, which is important for the astrophysically relevant reaction 15O( $\alpha$ , $\gamma$ )19Ne . Beta-delayed protons were used to obtain a more precise value for the half-life of 20 Mg, 91.4(1.0)ms
