This is an experimental and theoretical investigation of the dispersion of a round water jet discharging at various angles into a rectangular channel. A fundamental study of the jet is not only essential for a better understanding of the flow conditions produced by confined water jets but for a scientific approach to the design of hydraulic structures and to determine an efficient form of stilling basin for high velocity discharge from pipe outlets. The Laser Doppler Anemometry (LDA) technique was adapted for measurement of mean velocities and turbulence characteristics,, without any interference in the flow, and was utilised for the investigation of the complex three dimensional circulating flow which was experienced in the channel. In the experiments the inclination of the jet was varied from 45 to 90 degrees to the bed of the channel, while differing ratios of channel width and depth to jet diameter were studied for various Froude numbers. Detailed measurements of velocity decay, normal and lateral velocity profiles, distributions of pressure and turbulence characteristics have been carried out for selected flow conditions relating to the 45 degree oblique and vertical jet in order to determine the flow pattern and head dissipations. The experimental results have been analysed and compared with Glauert Is theory for a radial wall jet as a first approximation neglecting gravity forces when small compared with turbulent forces. Based on these results erosion experiments and model studies using a solid apron and a sand bed downstream, have been conducted to predict the minimum size of an efficient stilling basin and dimensions of any required blocks. Finally generalised design guide-lines and a standard code of practice have been developed for a stilling basin with high velocity pipe outlets. The research work will provide practical information and design procedures for consultants and other organisations working on the design and maintenance of a variety of water projects both in the UK and overseas.

Abstract: Introduction: Partial bladder outlet obstruction (pBOO) is a ubiquitous problem that results in renal damage. We hypothesize that change in the bladder progresses over time. Methods: Fischer rats underwent surgical pBOO for 2, 4, 8, or 13 weeks and were compared to shams. Urodynamic measurements were taken, bladders weight and thickness recorded, and tissue analyzed with microscopy. RT-PCR was performed for inflammatory mediators and spectrometry used to quantify collagen. Results: Urodynamics demonstrated an increased capacity and deterioration into high-pressure. H+E demonstrated an initial inflammatory response, and increased mRNA levels of TGF-, CTGF, HIF-1, and PDGF. Muscle hypertrophy was evident on H+E and increased bladder mass and thickness. Massons Trichrome and mass spectrometry showed an increase in collagen. Conclusion: We believe that this represents distinct phases of bladder decompensation: inflammation, hypertrophy, and fibrosis. This could lead to improved preventative strategies, with respect to biochemical pathways and the time course of their initiation. / Experimental Surgery

I've been studying the entrance to Iittala Outlet in Vingåker with the purpose of finding a way to make the entrance more distinct and also increase the accessibility, the orientation and the availability. With interviews and notations as a method I've determined the extent of the problem and the motions of the visitors at the outlet area. With further support from previous research and litterature I've made a design proposal. The design proposal contains a relocation of the parkinglots that opens up visible walkways to Iittala Outlet. / Jag har arbetat med entrén till Iittala Outlet i Vingåker i syfte att skapa en tydligare entré och finna ett sätt att öka framkomligheten, orienterbarheten och tillgängligheten. Med intervjuer och notationer som metod har jag fastställt problemets omfång och besökarnas rörelsemönster på outletområdet. Utifrån det har jag med tidigare forskning och litteratur som underlag arbetat fram ett gestaltningsförslag. Förslaget innefattar en parkeringsflytt som öppnar upp för tydliga gångvägar till Iittala Outlets entré.
