Combustion Diagnostics by Means of Multizone Heat Release Analysis and NO Calculation
In this paper a combustion diagnostic method is presented where measured pressure data is used to calculate the heat release, local temperatures and concentrations of NO and other species. This is done by a multizone model where the lambda value, i.e. 1/equivalence ratio, in each zone can be chosen arbitrarily. In homogenous charge engines lambda is given by the global air/fuel ratio. The local la
A postmodern saint? - on motives for voluntarism
Popular Abstract in Swedish Utgångspunkten för denna avhandling är de många bekymmer som präglar vår tid - däribland också bekymret om frivillighetens framtid i ett postmodernt samhälle. Det är en paradox, när det å ena sidan hävdas att det moderna samhället är i kris, att den sociala gemenskaperna har brutit samman och att människor inte längre ställer upp, engagerar sig och hjälper varandra. OchThe theme of this thesis is motives for voluntarism - with particular focus on volunteering in social work compared to voluntary work in sports clubs and patient associations. It is based on a combination of different data sources and methodological approaches: surveys, analyses of letters from volunteers and literature studies. Theoretically the thesis is based on two sets of sociological theorie

Influence of pH and surfactants on ultrafiltration membranes during treatment of bleach plant effluent
The influence of pH and surfactants during treatment of E-stage effluent was studied. Three tubular ultrafiltration membranes were used in the experiment. The flux of the three membranes was at its highest level at the normal, high pH, of the effluent. In this experiment the densest membrane showed the greatest flux decrease, while the most ouen membrane was either unaffected bv variations in ph o
Engagemang i Lutherhjälpen : studier av motiv och drivkrafter hos frivilligt aktiva
Popular Abstract in Swedish Del 1. Introduktion I kapitel 1 presenteras arbetets problem, syfte och metod. Det arbete som olika frivilligorganisationer och deras medlemmar utför har de senaste åren uppmärksammats alltmer. Detta ökade intresse finner man såväl i Sverige som internationellt. Fokus i detta arbete riktas mot drivkrafterna bakom frivilligt engagemang. Det övergripande problemet är varfThis thesis focuses on the incitement to commitment and voluntary work. The overall problem is the question why you get involved in voluntary work for an organisation like Lutherhjälpen, the organisation for international development co-operation of the Church of Sweden, one of the largest NGOs of the country. The theoretical perspectives are seen from the position of the increasing pace of change

Search for QCD instanton-induced processes in deep-inelastic scattering at HERA
Signals of QCD instanton-induced processes are searched for in deep-inelastic scattering (DIS) at the electron-proton collider HERA in a kinematic region defined by the Bjorken-scaling variables x > 10(-3), 0.1 < y < 0.6 and photon virtualities 10 less than or similar to Q(2) < 100 GeV2. Several observables characterising hadronic final state properties of QCD instanton-induced events are exploite

Genomics and the irreducible nature of eukaryote cells
Large-scale comparative genomics in harness with proteomics has substantiated fundamental features of eukaryote cellular evolution. The evolutionary trajectory of modern eukaryotes is distinct from that of prokaryotes. Data from many sources give no direct evidence that eukaryotes evolved by genome fusion between archaea and bacteria. Comparative genomics shows that, under certain ecological setti

Single attosecond pulse production with an ellipticity-modulated driving IR pulse
We theoretically study attosecond pulse production via high-harmonic generation using a driving laser pulse with a time-dependent ellipticity. The theoretical approach produces results that agree with our experimental data obtained using 35 fs driving laser pulses and is further used to study the generation of single attosecond pulses with shorter laser pulses. We find an equation for the duration
Tvinga verkligheten till innebörd : studier i Kjell Espmarks lyrik fram till och med Sent i Sverige
Popular Abstract in Swedish Framställningen är kronologiskt upplagd och uppdelad i två steg. Första delen av studien behandlar perioden från 1948-1961 och synar Kjell Espmarks envetna strävan efter en självständig poetik från gymnasieskriverierna fram till och med de tre första diktsamlingarna, Mordet på Benjamin (1956), Världen genom kameraögat (1958) och Mikrokosmos (1961). Därefter kartläggs deSince his1956 début Kjell Espmark (b. 1930) has played a seminal part in Swedish post-War literature as both a poet and a novelist, and as an academic. To this date Espmark has written a dozen books of poetry, several novels, and has published highly influential works on Modernist poetry. Espmark's poetry is generically heterogeneous, and although Espmark's first collections of poetry were publish
Histomorphological Changes after Renal X-Ray Arteriography Using Iodine and Gadolinium Contrast Media in an Ischemic Porcine Model.
Background: Gadolinium contrast media (Gd-CM) are regarded as non-nephrotoxic or considerably less nephrotoxic than iodine contrast media (I-CM), and have therefore come to be used as a substitute for I-CM in patients with renal insufficiency in a variety of radiographic examinations. Purpose: To investigate renal histomorphological changes caused by Gd-CM in comparison with I-CM after renal X-ra

Monitoring of cadmium in the chain from soil via crops and feed to pig blood and kidney
The relationships between cadmium (Cd) levels in soil, feed crops, feed concentrate, pig feed mixture, water, pig blood, and kidney from 49 farms were investigated and the possibility to use pig kidney as a bioindicator of available Cd in the agricultural environment was evaluated. There were correlations between Cd levels in soil and wheat, between wheat and barley, and between feed and kidney. T

PCR for the diagnosis of enteroviral meningitis
A 2-step 'semi-nested' enterovirus PCR was developed and applied to CSF and serum specimens from 27 consecutive patients with aseptic meningitis. CSF and sera from 8 patients with non-enteroviral diagnoses were included as negative clinical controls. Enterovirus RNA was detected in CSF by PCR in 15 of the patients with aseptic meningitis, compared with 6 by virus culture. Acute-phase sera proved p
