Last interglacial sea-level proxies in the glaciated Northern Hemisphere

Because global sea level during the last interglacial (LIG; 130–115 ka) was higher than today, the LIG is a useful approximate analogue for improving predictions of future sea-level rise. Here, we synthesize sea-level proxies for the LIG in the glaciated Northern Hemisphere for inclusion in the World Atlas of Last Interglacial Shorelines (WALIS) database. We describe 82 sites from Russia, northern Europe, Greenland and North America from a variety of settings, including boreholes, riverbank exposures and along coastal cliffs. Marine sediments at these sites were constrained to the LIG using a variety of radiometric methods (radiocarbon, uranium–thorium, potassium–argon), non-radiometric methods (amino acid dating, luminescence methods, electron spin resonance, tephrochronology) as well as various stratigraphic and palaeo-environmental approaches. In general, the sites reported in this paper do not offer constraint on the global LIG highstand, but rather evidence of glacial isostatic adjustment (GIA)-influenced sea-level positions following the Marine Isotope Stage 6 glaciation (MIS 6; 191–130 ka). Most of the proxies suggest that sea level was much higher during the LIG than at the present time. Moreover, many of the sites show evidence of regression due to sea-level fall (owing to glacial isostatic uplift), and some also show fluctuations that may reflect regrowth of continental ice or increased influence of the global sea-level signal. In addition to documenting LIG sea-level sites in a large swath of the Northern Hemisphere, this compilation is highly relevant for reconstructing the size of MIS 6 ice sheets through GIA modelling.

Search for rare Phi decays in pi+ pi_ gamma final state

A search for phi radiative decays has been performed using a data sample of about 2.0 million phi decays collected by the CMD-2 detector at VEPP-2M collider in Novosibirsk. From the selected e+ e- -> pi+ pi- gamma events the following results were obtained: B(phi -> f0(980) gamma) < 1x10-4 for destructive and B(phi -> f0(980) gamma) < 7x10-4 for constructive interference with the Bremsstrahlung process respectively, B(phi -> gamma -> pi+ pi- gamma) 20 MeV, B(phi -> rho gamma) < 7x10-4. From the selected e+ e- -> mu+ mu- gamma events B(phi -> mu+ mu- gamma) = (2.3+-1.0)x10-5 has been obtained for E of gamma> 20 MeV. The upper limit on the P,CP-violating decay eta -> pi+ pi- has also been placed: B(eta -> pi+ pi-) < 9x10-4 . All upper limits are at 90 % C.L.Comment: 18 pages, 7 figure

Directed Flow in 158 A GeV 208Pb^{208}Pb + 208Pb^{208}Pb Collisions

The directed flow of protons and positive pions have been studied in 158 A GeV Pb + Pb collisions. A directed flow analysis of the rapidity dependence of the average transverse momentum projected onto the reaction plane is presented for semi-central collisions with impact parameters of approximately 8 fm, where the flow effect is largest. The magnitude of the directed flow is found to be significantly smaller than observed at AGS energies and than RQMD model predictions.The directed flow of protons and positive pions have been studied in 158 A GeV Pb + Pb collisions.

Prognostic significance of delirium in the intensive care period of acute myocardial infarction

The aim: to identify the frequency and clinical features of delirium in acute myocardial infarction (AMI) in the conditions of the intensive care unit. Material and Methods. The study involved 104 patients (43,3% women and 56,7% men) with AMI during the stay at the intensive care unit. The average age was 68,0 [59,0-76,7] years. Delirium was diagnosed using the criteria questionnaire Moss-ICU. For neurodevelopmental testing we used screening tests and rating scales. Results. The incidence of delirium in patients in this category was 28,8%. Most frequently delirium develops in patients aged 60-89 years: in the age group 60-74 years 25,0%, in the group of 75-89 years 44,7%. Delirium developed in the 1-2 day stay in the intensive care unit and intensive care. The average duration of delirium was 7,7 days. Hypoproductive form of delirium was detected in 64,3% of all cases, hyperproductive form in 21,4% of patients, mixed form in 14,2% of patients. The occurrence of delirium is associated with an increase of the duration of stay at the intensive care unit at 6 times compared with patients without delirium. Conclusion. The presence of delirium greatly increases the probability of death in the reanimation period of acute myocardial infarction. Moss questionnaire and training of doctors to work with rating scales should be accepted in all ICU intensive care units for early diagnosis of delirium and immediate correction of disorders of consciousness in patients in critical condition
