PIV measurement of separated flow in a square channel with streamwise periodic ribs on one wall

In. this study, particle image velocimetry (PIV) is used to investigate the physical process of separated flow in a square channel roughened with periodically transverse ribs on one wall. The ribs obstruct the channel by 15% of its height and are arranged 12 rib heights apart. The Reynolds number based on the bulk-mean velocity and the corresponding hydraulic diameter of the channel, is fixed at 2

Temporal Changes in Population Structure of a Marine Planktonic Diatom

A prevailing question in phytoplankton research addresses changes of genetic diversity in the face of huge population sizes and apparently unlimited dispersal capabilities. We investigated population genetic structure of the pennate planktonic marine diatom Pseudo-nitzschia multistriata at the LTER station MareChiara in the Gulf of Naples (Italy) over four consecutive years and explored possible c

Injury markers predict time to dementia in subjects with MCI and amyloid pathology.

OBJECTIVES: Alzheimer disease (AD) can now be diagnosed in subjects with mild cognitive impairment (MCI) using biomarkers. However, little is known about the rate of decline in those subjects. In this cohort study, we aimed to assess the conversion rate to dementia and identify prognostic markers in subjects with MCI and evidence of amyloid pathology. METHODS: We pooled subjects from the VU Un

Patients' perceptions of their participation in discharge planning after acute stroke.

Aims and objectives. To describe stroke patients' perceptions of their participation in the discharge planning process and identify correlates of perceived participation. Background. Patients have the right to participate in discharge planning, but earlier research has shown that they are often dissatisfied with the information they receive and their involvement in goal-setting during discharge pl

Galectin-3 endocytosis by carbohydrate independent and dependent pathways in different macrophage like cell types.

BACKGROUND: Galectin-3 (the Mac-2 antigen) is abundantly expressed in both macrophage like cells and certain non-macrophage cells. We have studied endocytosis of galectin-3 as one important step relevant for its function, and compared it between variants of a macrophage like cell line, and non-macrophage cells. METHODS: Endocytosis of galectin-3 was observed by fluorescence microscopy and measur

Den fria men begränsade rörligheten

Rätten att röra sig fritt, inom och över nationsgränser, är ett ideal intimt förknippat med det moderna samhällets självförståelse. Att man kan bryta upp från en plats för att söka en annan, tillfällig eller permanent, vistelseort är en central del av vårt samhälles demokratiuppfattning. I synnerhet i dag är det påfallande hur starkt detta ideal framhävs. Berlinmurens fall och globaliseringen av a

Glutaredoxin-1 mediates NADPH-dependent stimulation of calcium-dependent insulin secretion.

Nicotinamide adenine dinucleotide phosphate (NADPH) enhances Ca(2+)-induced exocytosis in pancreatic beta-cells, an effect suggested to involve the cytosolic redox protein glutaredoxin-1 (GRX-1). We here detail the role of GRX-1 in NADPH-stimulated beta-cell exocytosis and glucose-stimulated insulin secretion. Silencing of GRX-1 by RNA interference reduced glucose-stimulated insulin secretion in b

Residential preferences for interregional migration in Sweden: demographic, socio-economic and geographical determinants

Policy makers are showing increasing interest in factors that make places attractive for prospective new residents. This paper focuses on residential preferences for interregional migration and aims to explore what place attributes people would value highly if they considered migrating. Special attention is given to differences in preferences between population subgroups in terms of demographic, s

Study of Trace Elements Water in the Vicinity of Palosi Drain, Peshawar

Research study was conducted from January to May, 2002 in residential areas along the Palosi Drain, Peshawar. Main objective of the study was to evaluate water quality of shallow and deep wells in the vicinity of Palosi Drain. For this purpose, 20 water samples were taken 13 from shallow wells, 3 from deep wells and 4 from wastewater in the Palosi Drain. Water samples were analyzed for heavy metal
