Lack of Accuracy for the Proposed 'Dubois Criteria' in Alzheimer's Disease: A Validation Study from the Swedish Brain Power Initiative

Background/Aims: Our purpose was to investigate whether the new research criteria for Alzheimer's disease proposed in 2007 by Dubois et al. are valid in a naturalistic memory clinic sample. Method: Retrospective diagnostic analyses were carried out to compare the traditional diagnostic criteria for dementia with the new criteria suggested by Dubois et al. No patient had gone through all procedures

Rotational properties of nondipolar and dipolar Bose-Einstein condensates confined in annular potentials

We investigate the rotational response of both nondipolar and dipolar Bose-Einstein condensates confined in an annular potential via minimization of the energy in the rotating frame. For the nondipolar case we identify certain phases which are associated with different vortex configurations. For the dipolar case, assuming that the dipoles are aligned along some arbitrary and tunable direction, we

CFD Simulation of Heat Transfer and Pressure Drop in Compact Brazed Plate Heat Exchangers

In this paper, the thermal and hydraulic characteristics of corrugated fluid channels of compact brazed plate heat exchangers (BPHE) are investigated by computational fluid dynamics (CFD) simulations using the commercial CFD software ANSYS CFX 14.0. The influence of geometry parameters of the corrugated pattern such as chevron angle and corrugation pitch on the BPHE performance is investigated on

Asymmetric isolating barriers between different microclimatic environments caused by low immigrant survival.

Spatially variable selection has the potential to result in local adaptation unless counteracted by gene flow. Therefore, barriers to gene flow will help facilitate divergence between populations that differ in local selection pressures. We performed spatially and temporally replicated reciprocal field transplant experiments between inland and coastal habitats using males of the common blue damsel

Effect of Transition Metal Fluorides on the Sorption Properties and Reversible Formation of Ca(BH4)(2)

Light metal borohydrides are considered as promising materials for solid state hydrogen storage. Because of the high hydrogen content of 11.5 wt % and the rather low dehydrogenation enthalpy of 32 kJ mol(-1)H(2), Ca(BH4)(2) is considered to be one of the most interesting compounds in this class of materials. In the present work, the effect of selected TM-fluoride (TM = transition metal) additives

Flexible waste management under uncertainty

In this paper, we use stochastic dynamic programming to model the choice of a municipality which has to design an optimal waste management program under uncertainty about the price of recyclables in the secondary market. The municipality can, by undertaking an irreversible investment, adopt a flexible program which integrates the existing landfill strategy with recycling, keeping the option to swi

Har små och medelstora företag konkurrensfördelar av miljöledningssytem?

Denna undersökning, som är finansierad av NUTEK, besvarar frågan om små och medelstora företag har några konkurrensfördelar av ett standardiserat miljöledningssystem (ISO 14001). Som utgångspunkt för undersökningen har en djupintervju med 30 ISO 14001-certifierade små och medelstora företag i södra Sverige använts. Dessa resultat har sedan jämförts med en enkätundersökning som skickats till övriga

Protein kinase C in porcine retinal arteries and neuroretina following retinal ischemia-reperfusion.

PURPOSE: Identification of the intracellular signal-transduction pathways activated in retinal ischemia may be important in revealing novel pharmacological targets. To date, most studies have focused on identifying neuroprotective agents. The retinal blood vessels are key organs in circulatory failure, and this study was therefore designed to examine the retinal vasculature separately from the neu

No Risk of Maternal EBV Infection for Childhood Leukemia.

We performed a large nested case-control study within the Finnish and Icelandic maternity cohorts to verify/falsify the association of maternal EBV infection with an increased risk of acute lymphoblastic leukemia (ALL) in the offspring found in previous studies. All hematologic malignancies diagnosed among children born during 1983 to 2006 in Finland and 1997 to 2005 in Iceland were identified thr
