Demonstration of a tool for automatic learning and reuse of knowledge in the activated sludge process

Wastewater treatment plant operators encounter complex operational problems related to the activated sludge process and usually respond to these by applying their own intuition and by taking advantage of what they have learnt from past experiences of similar problems. However, previous process experiences are not easy to integrate in numerical control, and new tools must be developed to enable re-

Study of the Energy Use Characteristics of Concrete Multi Family Dwelling Buildings and the Relevance for Economy and Environment

Reduction of energy use in buildings is fundamental for sustainable development. A computer program for the prediction of energy use in buildings was assessed by comparisons with the energy performance of existing buildings. The program was then used to evaluate the energy saving characteristics of concrete such as air tightness and heat capacity. The impacts on global environmental aspects and li

Dietary manipulation of the sow milk does not influence the lipid absorption capacity of the progeny

A control diet without supplemental fat and four diets containing 8% of coconut oil, rapeseed oil, fish oil or sunflower oil were fed to lactating sows in order to investigate the lipid absorption capacity of their progeny in terms of pancreatic enzyme activity, hormonal regulation, and bile salt concentration. In addition, the effect of age was studied during the four week suckling period, and du

Influence of the membrane material on the adsorptive fouling of ultra-filtration membranes

The hydrophilic/hydrophobic properties of the membrane material have an important influence on the membrane flux reduction when treating solutions containing hydrophobic solutes. Different methods of measuring the hydrophobic properties of membranes have been evaluated; measurement of the contact angle being the most commonly used method. In this investigation the flux reduction of eight membranes

Recursive Structure and Motion from Image Sequences using Shape and Depth Spaces

In this paper a novel recursive method for estimating structure and motion from image sequences is presented. The novelty lies in the fact that the output of the algorithm is independent of the chosen coordinate systems in the images as well as the ordering of the points. It relies on subspace methods and is derived from both ordinary coordinate representations and camera matrices and from a so ca

Arbete i kyla vid mjölkproduktion - klimatets påverkan på arbetsmiljön

Hur påverkar kylan arbetsmiljön i mjölkproduktionen? De som arbetar med mjölkproduktion kan under vintern ha en mycket kylig miljö. JTI har, i samarbete med Arbetslivsinstitutet, gjort mätningar och studier kring hur kylan påverkar arbetsmiljön. JTI:'s och Arbetslivsinstitutet's mätningar visar att de största problemen med kyla observerade's för händerna i samband med spolning av golv, arbete på s

Bortom riksbildningen : människor, landskap och makt i sydöstra Skandinavien

Popular Abstract in Swedish Den danska riksbildningen presenteras vanligen som en linjär process som knyter ihop forntida hövdingar med den moderna nationalstaten. Avhandlingen fokuserar de små berättelserna bortom den stora berättelsen om Danmark. Avhandlingen argumenterar för att den tidigare forskningen kring den danska riksbildningen kan delas in i tre huvudlinjer: 1. Den danska riksbildningeThe formation of the kingdom of Denmark is generally presented as a linear process linking ancient chiefs to the modern nation state of Denmark. This dissertation focuses on the small stories behind this great narrative of Denmark. The purpose is to show that there never was any formation process. Instead, encounters between people in the local landscapes and the Danish kingdom were both considera

Persistent collateral perfusion of abdominal aortic aneurysm after endovascular repair does not lead to progressive change in aneurysm diameter

PURPOSE: To differentiate between the phenomenon of collateral perfusion from a side branch versus graft-related endoleaks after endovascular repair of abdominal aortic aneurysms (AAA), with respect to aneurysm size and prognosis. METHODS: We successfully treated 64 AAA patients with endovascular grafting. We followed all the patients postoperatively with spiral computed tomography at one, three,

Magnetic anisotropy of ultrathin cobalt films on Pt(111) investigated with x-ray diffraction: Effect of atomic mixing at the interface

With standard and resonant x-ray magnetic diffraction we investigate the magnetic properties of Pt atoms in a Co/Pt(111) system. It is shown, that, depending on the thickness of the Co films, the magnetic anisotropy as monitored by the Pt magnetism changes from perpendicular to parallel, mimicking the behavior of the Co overlayer. Adsorption of carbon monoxide on very thin films has been found to

Definition of a VR-based protocol to treat social phobia

Social phobia is an anxiety disorder that is accessible to two forms of treatment yielding scientifically validated results: drugs and cognitive-behavioral therapies. Graded exposure to feared social situations is fundamental to obtain an improvement of the anxious symptoms. Traditionally, exposure therapies are done either in vivo or by imagining the situations. In vivo exposure is sometimes diff

Inherited susceptibility to acute pyelonephritis: a family study of urinary tract infection.

Background. Urinary tract infections (UTIs) are important causes of morbidity and death. The present study investigated whether genetic factors influence susceptibility to acute pyelonephritis (APN). CXCR1 expression was investigated as a factor predisposing to APN, because low CXCR1 expression has been associated with disease susceptibility in mice and disease-prone children. Methods. The familie
