Determination of Particle Deposition Velocity onto the Human Eye

Studies have been performed on the deposition of airborne particles onto the human eye. A mannequin with sticky transparent foils covering its eyes is exposed to particles of fused alumina in a wind tunnel. The size distribution of the airborne particle is simultaneously measured with an Aerodynamic Particle Sizer. The particles on the foils are counted and measured with an optical microscope conn

Corporate Brand Positioning – A Process Perspective

The purpose of this paper is to explore the process of positioning a corporate brand in the context of a global industrial organization. A process-focused single case study helped to generate detailed qualitative data to understand how management activities and choices in positioning the corporate brand occurred over time. The paper offers two main contributions: (1) It identifies seven stages of

On the distribution of relevant radio channel figures in different propagation environments for performance evaluation of WCDMA systems

A statistical distribution for the number of CDMA RAKE fingers, N T, to be assigned in order to track a given percent of the total received power has been derived. The obtained distribution reveals a strong dependence of NT on the system bandwidth, the median RMS delay spread, its standard deviation and other environment specific parameters. Also, a statistical distribution for the fading width fw

A computational framework for risk-based power system operations under uncertainty. Part I: Theory

With larger penetrations of wind power, the uncertainty increases in power systems operations. The wind power forecast errors must be accounted for by adapting existing operating tools or designing new ones. A switch from the deterministic framework used today to a probabilistic one has been advocated. This two-part paper presents a framework for risk-based operations of power systems. This framew

A Methodology for Operations Planning

The key to successful manufacturing of complicated geometry in numerically controlled machines lies in the control and quality of operations planning. This thesis presents a methodology for automated operations planning for milling with five axes. The goal in this research has been to develop a methodology to achieve complicated machining faster than today. The result is a methodology that uses pl

Production of recombinant PSA and HK2 and analysis of their immunologic cross-reactivity

Measurements of prostate-specific antigen (PSA) in serum are widely used to monitor patients with prostate cancer, but the attenuation of the assay response by PSA complexed to protease inhibitors has been shown to affect the results in certain assay designs. Moreover, the human glandular kallikrein-2 (hK2), a kallikrein-like serine protease that is 80% similar to PSA, might interfere with the spe

Nitritation and denitritation in sludge liquor treatment

Popular Abstract in Swedish Övergödningen av Östersjön är fortfarande ett problem. Förhöjda krav på kvävereduktion för de svenska avloppsreningsverken är därför att vänta. Detta innebär i sig ökad energi- och kemikalieförbrukning, vilket rimmar illa med ord som energieffektivisering och resurssnålhet. Biologisk kväverening av en specifik delström på reningsverket har dock potential att minska ytbeEnhanced biological nitrogen removal at municipal wastewater treatment plants is a common procedure to prevent eutrophication in water bodies. Increased load, stricter effluent regulations, and demands for reduced resource and energy consumption present new challenges for the wastewater treatment plants. One option when upgrading a wastewater treatment plant is to treat the sludge liquor produced
