Lithostratigraphy of the Late Saalian to Middle Weichselian Skaerumhede Group in Vendsyssel, northern Denmark

The Quaternary sedimentary succession in Vendsyssel, northern Denmark, contains a unique, high-resolution record of the last interglacial and glacial periods. There is still much debate, however, about the timing and ice extent in this southwestern part of the Scandinavian Ice Sheet, particularly during the Middle Weichselian. In this study, a detailed lithostratigraphical subdivision is establish

The social life and attitudes of 80 year olds in Iceland and Sweden - A comparison of two city populations

The 80+ Studies are collecting longitudinal data regarding medical, psychological, and sociological aspects of 80-year-old people in Lund, Sweden and Reykjavik, Iceland. Methods and Samples: The research design and instruments were identical at the two cites. The number of participants was 139 and 151 respectively. Results: The Icelandic sample had a lower level of educational attainment, a higher

Relaxed dynamic programming in switching systems

In order to simplify computational methods based on dynamic programming, a relaxed procedure based on upper and lower bounds of the optimal cost was recently introduced. The convergence properties of this procedure are analysed here. In particular, it is shown that the computational effort in finding an approximately optimal control law by relaxed value iteration is related to the polynomial degre

Resisting resistance: Counter-resistance, consent and compliance in a consultancy firm

Consent, obedience and resistance can be seen as key concerns in management and organization. Why people comply is a crucial issue in the field. We address the theme within a specific area: management consultants in a big firm that places quite a lot of pressure on its personnel to be hardworking and predictable and to subordinate themselves to hierarchy, standards and tight production schedules.

Anderson localization of a weakly interacting one-dimensional Bose gas

We consider the phase coherent transport of a quasi-one-dimensional beam of Bose-Einstein condensed particles through a disordered potential of length L. Among the possible different types of flow we identified [T. Paul, P. Schlagheck, P. Leboeuf, and N. Pavloff, Phys. Rev. Lett. 98, 210602 (2007)], we focus here on the supersonic stationary regime where Anderson localization exists. We generalize

An imaging system for monitoring receptive field dynamics

The paper describes a computerized method, termed receptive field imaging (RFI), for the rapid mapping of multiple receptive fields and their respective sensitivity distributions. RFI uses random stimulation of multiple sites, in combination with an averaging procedure, to extract the relative contribution from each of the stimulated sites. Automated multi-electrode stimulation and recording, with

Cartilage oligomeric matrix protein: isolation and characterization from human articular cartilage

Cartilage oligomeric matrix protein was purified in a native form from normal adult human articular cartilage. The key steps in the purification scheme were selective extraction with buffer containing EDTA, wheat germ agglutinin affinity chromatography, and removal of the related protein thrombospondin by heparin affinity chromatography. Particles of cartilage oligomeric matrix protein viewed by e

Artery blood pressure oscillation after active standing up: an indicator of sympathetic function in diabetic patients

Dynamic artery blood pressure (Finapres) response to active standing up, normally consisting of initial rise, fall and recovery above the baseline (overshoot), was compared with the early steady-state artery blood pressure level to measure sympathetic vasomotor function in healthy subjects (n = 23, age 35 +/- 9 years; mean +/-SD) and in type I diabetic patients without autonomic neuropathy (AN) (g

Partial splenic embolization as pretreatment for antiviral therapy in hepatitis C virus infection

Antiviral therapy in hepatitis C virus (HCV) infection is limited by haematological side-effects, especially thrombocytopenia and leucopenia. The pancytopenia associated with liver cirrhosis has multifactorial causes, but hypersplenism seems to be a major contributor, especially regarding thrombocytopenia. The use of PSE as a 'Pretreatment' in order to make more patients with HCV-induced cirrhosis

The effect of moisture gradients on tensile strength perpendicular to grain in glulam

Experimental results are presented concerning tension perpendicular to grain in glulam sections where internal stresses induced by climate changes are present. The results reveal that moisture induced internal stresses may affect the tension capacity both in a positive and a negative way compared to reference specimens, free from moisture gradients. The tension capacity is reduced during moistenin

Effect of calmodulin antagonists on phospholipase D activity in SH-SY5Y cells.

The aim of this study was to investigate the involvement of calmodulin in phospholipase D activation in SH-SY5Y cells. Cells prelabelled with [3H]-palmitic acid were incubated with calmodulin antagonists and/or other compounds. Phosphatidylethanol, a specific marker for phospholipase D activity, and phosphatidic acid were analysed. The calmodulin antagonists, calmidazolium and trifluoperazine, ind

Autologous and allogeneic stem cell transplantation in adult ALL: the Swedish Adult ALL Group experience

Adult patients with acute lymphoblastic leukaemia ( ALL) have been treated according to national protocols in Sweden since 1986. Stem cell transplantation (SCT) has been recommended in first remission for patients with risk factors for relapse, and for standard risk patients only after relapse. In this retrospective study, the results of autologous and allogeneic SCT in these populations were eval

The genus Microdonophagus Schauff (Hymenoptera: Eulophidae), with description of a new species

A second species of the hitherto monotypic genus Microdonophagus Schauff is described as Microdonophagus levis sp. nov. The species is described from material collected at La Selva Biological Research Station in Costa Rica. Unlike the previously described species, Microdonophagus woodleyi Schauff, it is described from females only and the biology is not known. The addition of a second species of M

Time-dependent quantum transport: An exact formulation based on TDDFT

An exact theoretical framework based on Time Dependent Density Functional Theory (TDDFT) is proposed in order to deal with the time-dependent quantum transport in fully interacting systems. We use a partition-free approach by Cini in which the whole system is in equilibrium before an external electric field is switched on. Our theory includes the interactions between the leads and between the lead
