PIV MEASUREMENTS OF TURBULENT FLOW IN A CHANNEL WITH SOLID OR PERFORATED RIBS

Particle image velocimetry measurements are performed in a channel with periodic ribs on one wall. We investigate the flow around two different rib configurations: solid and perforated ribs with a slit. The ribs obstruct the channel by 20% of its height and are arranged 10 rib heights apart. For the perforated ribs, the slit height is 20% of the rib height, and the open-area ratio is 16%. We discu

IMPLEMENTING NATIONAL POLICY AND LOCAL PLANNING - Swedish wind power development and third generation mobile phone system as cases

The paper analyses the permit process for Swedish wind power development in terms of two paradigms of spatial planning and environmental management, and makes a comparison with the Swedish 3G mobile phone infrastructure development. Swedish Parliament has set a goal of 10 TWh annually wind electricity for 2015, and the Swedish Energy Agency has proposed 30 TWh from wind power by 2020. The present

Empirical Essays on Health and Human Capital

This thesis includes one introductory chapter and three independent papers. The first paper adds to the broad literature regarding the effect of alcohol consumption on educational attainment. Given that no consensus exists in the literature regarding this paper adds to the literature by analyzing the effect of alcohol consumption on educational attainment using a life cycle approach. In addition

Anatomical, neurochemical and behavioural consequences of immunotoxin lesions of the basal forebrain cholinergic system.

The cholinergic hypothesis of geriatric memory dysfunction suggests that the learning and memory deficits representing the cardinal symptoms of dementia in the aged and in patients suffering from Alzheimer's disease may be attributable to a decline in the function of the cholinergic projection systems of the basal forebrain. Although many studies have addressed the issue of a causal relationship b

Common evolutionary origin of alpha 2-macroglobulin and complement components C3 and C4

A comparison of the sequence of the subunit of human alpha 2-macroglobulin (alpha 2M; 1451 amino acid residues) with that of murine complement component pro-C3 (1639 amino acid residues) reveals eight extended regions of sequence similarity. These regions contain between 19% and 31% identically placed residues and account for 75% and 67%, respectively, of the polypeptide chains of alpha 2M and pro
