Anaerobic digestion (AD) is a biochemical process in nature. It has been used to decompose organic waste in order to reduce environmental pollution, and to destroy pathogenic microorganisms for the protection of human and animal health. The process itself produces methane, which can then be used as an energy source. The use of AD in an integrated resource recovery system is one of the most importa

Popular Abstract in Swedish Graviditetsdiabetes (GD) är en sjukdom utan någon allmänt erkänd definition och vars prognos för kvinnan och hennes foster/barn är omdiskuterad. Därför har det från etisk synpunkt ifrågasatts om man verkligen ska försöka identifiera den. Rapporter har dock angivit ökad risk att få stora barn för tiden och ökad perinatal dödlighet vid graviditetsdiabetes samt att dessa kGestational diabetes (GD) is still a nonentity disease. There is no worldwide consensus how to define it or whether it is harmful to the woman or fetus. Therefore, from an ethical point of view, it is uncertain whether one should try to identify it. Since 1991, all pregnant women in Lund are offered a 75g oral glucose tolerance test (OGTT) at 27 – 28 weeks of pregnancy. In Sweden, the definition o

While traditionally treated separately, the research disciplines dealing with electromagnetic fields respectively continuum mechanics are naturally connected. Not only are the basic equations formulated in a similar way, but the presence of electromagnetic fields affect the balance equations of continuum mechanics and likewise, the presence of material continua affect the electromagnetic fields

Visual quality assurance techniques focus on the detection and qualification of abnormal structures in the image of an object. The features of abnormality are extracted through image mining, whereupon classification is performed on characteristic combinations. Many techniques for feature extraction have been proposed, but the feed-forward neural network is seldom utilized despite its popularity in

The substitution in varying amounts of strontium (Sr) for calcium in the alpha tricalcium phosphate (α TCP) structure was investigated. The effects on the reactivity towards the formation of hydroxypalatite on hydration were also studied. The prepared α-TCP and the fully hydrated α-TCP powders were characterized by means of X-ray diffraction and the CuKα1 radiation. It was found that the alpha for

In this paper we evaluate the use of parallel interleavers for user separation in coded IDMA systems. The parallel interleavers have previously been evaluated for uncoded systems, and we here present extended results for the coded case. The new results are important for real systems, as they will most likely use performance enhancing channel coding. The parallel interleavers are designed to remove
