Towards a Better Understanding and Control of Factors Affecting the Physical Quality of Fish Feed

Popular Abstract in English Fish are an excellent source of healthy protein and fat in the human nutrition. However, the fisheries cannot supply enough of fish to satisfy the demand of a growing world’s population. Sustainable aquaculture can help feeding the growing world. This business is growing every year, and together with it the fish farms and fish feed factories are growing. This created thAs aquaculture expands, the volume of fish feed produced and transported must also increase. Therefore a better understanding and increased control of the factors that influence the physical quality of feed pellets is required. To achieve this goal, reliable methods measuring the physical quality of feed are needed. The Holmen pellet tester (NHP 100) could be adapted for this purpose, but the spec

Reconciling nu-Gap Metric and IQC Based Robust Stability Analysis

This technical note elaborates on the flexibility of an approach that combines nu-gap metric and integral quadratic constraint (IQC) based analysis in the study of uncertain feedback interconnections of distributed-parameter transfer functions. It is established that a standard ν-gap ball robust stability result can be recovered within the blended IQC/nu-gap framework, which only requires the exis

A catalyst for catalytic oxidation of hydrocarbons

A catalyst having resistance towards Si and/or P deactivation in catalytic oxidation of organic hydrocarbons is disclosed. The catalyst comprises a catalytically inert support, a catalytically active layer of metallic Pt and/or Pd and deposited on said catalytically active layer at least one oxide ...

Detailed Numerical Simulations of Turbulent Premixed Flames at Moderate and High Karlovitz Numbers

Popular Abstract in Swedish Förblandad förbränning har sedan lång tid tillbaka varit en av grundbultarna i industriellt applicerad förbränning såsom i bensinmotorer och gasturbiner. Genom att direkt kunna kontrollera blandningsförhållandet mellan bränsle och luft kan utsläppen av skadliga ämnen hållas på en minimal nivå. Detta gör förblandad förbränning mycket attraktiv. För att industriellt appliIn generally accepted and applied flamelet combustion models, a turbulent flame is mainly assumed distorted by the large-scale turbulence eddies, whereas small-scale turbulence effects on the local flamelet structures are neglected. However, in a lot of industrial applications rather high turbulent intensities are often imposed, which induce turbulence scales at ranges smaller than the flame thick

Improving radioimmunotargeting of tumors : the impact of extracorporeal immunoadsorption and preload in rats

In radioimmunotherapy of tumors, uptake of the monoclonal antibody (MAb) used is often too low in relation to its uptake in normal tissues. The purpose of these studies was to improve experimental tumor radioimmunotargeting with (a) extracorporeal immunoadsorption (ECIA), where excess of radiolabeled MAbs circulating in blood is removed, (b) or by preload with unlabeled MAb prior to injection of r
