Close collaboration is considered important; but is close collaboration for all purchases necessary to create value-in-production? In construction as well as in other industries, companies purchase a variety of items that require different amounts of attention to the relationship with suppliers. Buyer-supplier relationships are investigated in relation to how they bring value-in-production in the
Humidified gas turbines (HGT) offer the attractive possibility of increasing plant efficiency without the cost of an additional steam turbine as is the case for a combined gas-steam cycle. In addition to efficiency gains, adding steam into the combustion process reduces NOx emissions. It increases the specific heat capacity (hence, lowering possible temperature peaks) and reduces the oxygen concen
Popular Abstract in Swedish Produkternas miljöpåverkan har varit en av de stora nya frågorna sedan 10-15 år tillbaka. Att det uppstår betydande miljöproblem under en varas hela livscykel förstod man snart, men frågan var vad man kunde göra åt det. Jag kom att arbeta med återvinningsfrågor under senare hälften av 1980-talet. Det var också vid den tiden som förebyggande miljöskyddsstrategier börjadeThe focus of the environmental policy-making has shifted noticeably during the last decade. From having played a fairly insignificant role in the 1980s and earlier, product-related environmental problems have attracted an ever-increasing interest from policy-makers, especially in industrialised countries in North-Western Europe. Considerable attention has been devoted to the concept of extended pr
In precision hard turning, tool flank wear is one of the major factors contributing to the geometric error and thermal damage in a machined workpiece. Tool wear not only directly reduces the part geometry accuracy but also increases the cutting forces drastically. The change in cutting forces causes instability in the tool motion, and in turn, more inaccuracy. There are demands for reliably monito
The hypotheses of this investigation were based on attachment theory and Bowlby's conception of “internal working models”, supposed to consist of one mainly emotional (model-of-self) and one more conscious cognitive structure (model-of-others), which are assumed to operate at different temporal stages of information processing. Facial muscle reactions in individuals with positive versus negative i
Signal processing can be used to condition medical signals to facilitate their interpretation, and to extract clinically important information. The purpose of the present doctoral thesis is to put forward solutions to certain problems encountered in the processing of electrocardiac signals. Paper I examines the properties of a maximum likelihood method for aligning vectorcardiographic loops, with
The basic hypothesis is that mind is an emergent property of the processes that produce natural language expressions. The shape of the mind of a particular person can be discovered through the mechanisms forming the corresponding language space. Although covered by textual surface properties, this space is approachable with VERTEX, which is a new version of Perspective Text Analysis (PTA). Due to
A mathematical model modified from the well established Activated Sludge Model no. 1 was used for modelling a full-scale wastewater treatment plant (WWTP) in a bleached kraft pulp mill. Effluents from the pulp and paper industry are typically nutrient deficient, which was considered in the model. The wastewater characterization and model calibration were based on respirometric batch experiments wi
Due to increasing oil demand and serious global warming, a green power generation system is urgently requested in transportation. Electric/hybrid vehicles (EV/HEV) have been considered as a potential solution with great promise in achieving high energy/power efficiency and a low environmental impact. The important electric and electronic equipment in EV/HEV are the battery, inverter and motor. How
Most robots today can trace their origin to early industrial robot designs. Much of the technology that makes robots more human-friendly and adaptable for different applications has emerged from manufacturers of industrial robots. Industrial robots are by far the largest commercial application of robotics technology today. All the important foundations for robot control were initially developed wi
We analyze empirically product-price variation across export destinations using detailed firm-product data. Most recent studies using highly disaggregated data emphasize variations in product quality as an explanation as to why firms charge different prices for the same product on different export markets. In this paper, we take an alternative approach and assume that variations in firms' export p
The Swedish National Road Administration SNRA is responsible for the long term de-velopment of the road transport system, and spends large sums on road construction and 'operation and maintenance'. Improvements in efficiency which are small in per-centage terms therefore yield relatively large monetary effects. In order to create and maintain a strong and competitive road construction sector and a
Since very few products are truly lifecycle adapted, most products need supportive functions during part(s) of their lifecycle — ranging from extensive systems of primary, secondary and tertiary packages to a simple wrapping or chemical surface protection. When a package is needed, consideration is seldom given to it during the actual development of the product. See Bramklev (2004). An illustrat
The aim of the present study was to investigate how people with persistent mental illness, with various types of work and employment conditions, experience and describe the meaningfulness of work. The study had a qualitative approach and twelve informants living in the community were purposefully selected and interviewed according to overarching themes. The interviews were analysed using qualitati
In this work, we reconstructed in vitro the behavior of two motor proteins-myosin and actin-responsible for the mechanical action of muscle cells. By transferring this in vivo system to an artificial environment, we were able to study the interaction between the proteins in more detail, as well as investigating the central mechanism of force production. Nm-patterning by e-beam lithography (EBL) co
In order to meet the expected enormous demand for mass spectrometry (MS)through-, put as a result of the current efforts to completely map the human proteome, this paper presents a new concept for low-cost high-throughput protein identification by matrix assisted laser desorption/ionization-time of flight-(MALDI-TOF)-MS peptide mapping using disposable polymeric high-density nanovial MALDI target
Background: Legislation was passed in Sweden to stimulate the development of different housing solutions for persons suffering from severe mental illness. Among these solutions are small congregate residences built in the community to provide suitable housing and support for those not able or willing to live independently. Aims: The general aim of the present study was to compare the psychosocial
Inclusive e(+/-)p single and double differential cross sections for neutral and charged current deep inelastic scattering processes are measured with the H1 detector at HERA. The data were taken at a centre-of-mass energy of root s = 319 GeV with a total integrated luminosity of 333.7 pb(-1) shared between two lepton beam charges and two longitudinal lepton polarisation modes. The differential cro
