The characteristics of aerosol particles formed during combustion of moist forest residue were studied as a function of load in a I MW moving grate boiler and at almost full load in a similar larger 6 MW boiler. The coarse (1 mum < d(ae) < 10 mum) particle number and mass concentration increased by more than one order of magnitude and the fine particle mean diameter, total volume and mass decrease

The purpose of this thesis is to explore whether access to justice in Guatemala can be provided for the Mayan population by the use of their own justice system and what the consequences of its application would be. Prohibiting factors are economical, geographical, linguistic, cultural and institutional in nature. It is clearly the indigenous people that suffer most from the lack of the basic right

Background: Asthma genetics has been extensively studied and many genes have been associated with the development or severity of this disease. In contrast, the genetic basis of allergic rhinitis (AR) has not been evaluated as extensively. It is well known that asthma is closely related with AR since a large proportion of individuals with asthma also present symptoms of AR, and patients with AR hav

The initial stages of stress corrosion on an amorphous polymer is investigated. This is done by exposing stressed specimens of polycarbonate to an acetone and water solution. The surface develops two distinct features of degradation that appear on different length scales when subjected to tensile stress. Small pits form on the surface and make it rough. These pits are in the order of micrometers,

Experimentally determined activation energies of propane dehydrogenation catalyzed by ZSM-5 zeolites have been used to test the SET theory. The basis of this theory is that the catalyst system transfers vibrational energy via a resonance process to a specific vibration mode of the reacting molecule. Being excited up to a certain number of vibrational quanta the molecule is brought to reaction. By

Questions: How does the number of species in a community affect the level of genetic diversity of its constituent species? What is the relation between competitive interactions and the spatial distribution of genetic variation? When spatially structured, how is the genetic differentiation among subpopulations affected by competition and size of the community? Model features and key assumptions: A

Life-history theory predicts that individuals should adjust their reproductive effort according to the expected fitness returns on investment. Because sexually selected male traits should provide honest information about male genetic or phenotypic quality, females may invest more when paired with attractive males. However, there is substantial disagreement in the literature whether such differenti

Vem hjälper andra – och när? Denna studie undersökte situationsbaserade och individbaserade faktorers påverkan på hjälpbeteende. Studien bestod av en enkät om personlighetsdrag och världsbild samt en fiktiv annons för en välgörenhetsorganisation som delades ut till de 130 deltagarna. Annonsen utformades i två versioner, där hälften av deltagarna fick en version som spelade på en positiv känsla (waWho helps others – and when? This study examined situation based and individual based factors’ impact on helping behaviors. The study consisted of a survey about personality traits and worldview, and a fictive ad from a charity organization, which were handed out to 130 participants. The ad was designed in two versions, where half of the participants were assigned a version which simulated a posit

Using the ATLAS detector, a centrality-dependent suppression has been observed in the yield of J/psi mesons produced in the collisions of lead ions at the Large Hadron Collider. In a sample of minimum-bias lead-lead collisions at a nucleon-nucleon centre of mass energy root s(NN) = 2.76 TeV, corresponding to an integrated luminosity of about 6.7 mu b(-1), J/psi mesons are reconstructed via their d

We consider the following signaling game. Nature plays first from the set {1,2}{1,2}. Player 1 (the Sender) sees this and plays from the set {A,B}{A,B}. Player 2 (the Receiver) sees only Player 1’s play and plays from the set {1,2}{1,2}. Both players win if Player 2’s play equals Nature’s play and lose otherwise. Players are told whether they have won or lost, and the game is repeated. An urn sche

Subject-verb agreement in number (3sg - 3pl) in spoken French is a heterogeneous morpho-syntactic domain where number is expressed in some groups of verbs and in some phonological contexts only. The acquisition of this agreement is a long and gradual process (Prévost, 2009). Both children learning French as their first language (L1) and older second language (L2) learners overuse the dominant patt

A test of the benchmark QED process e(+) e(-) -->gammagamma(gamma) is reported, using the data collected with the DELPHI detector at LEP 2. The data analysed were recorded at centre-of-mass energies ranging from 161 GeV to 208 GeV and correspond to a total integrated luminosity of 656.4 pb(-1). The Born cross-section for the process e(+) e(-)-->gammagamma(gamma) was determined, confirming the vali

A resampling method for quantitative MRS is presented that retains absolute concentrations. Averaging the spectra from a subset improved the concentrationestimates via increased SNR. Using short-TE STEAM spectra from human thalamus, the influence of subset size was systematically studied and verifiedagainst conventional bootstrap re-sampling. Even small subsets provided considerably better signal-

Towards a theory of regional diversification: combining insights from Evolutionary Economic Geography and Transition Studies. Regional Studies. This paper develops a theoretical framework of regional diversification by combining insights from Evolutionary Economic Geography and Transition Studies. It argues that a theory of regional diversification should not only build on the current understandin

The estimation of the number of defective tendons in post-tensioned concrete bridges is a key input for the reliability assessment of prestressed girders. However, special inspection methods for detecting voids and assessing tendon condition are intrusive, time-consuming, and costly, and the quantitative definition of an inspection sample size that meaningfully reduces epistemic uncertainty while

The main purpose of this paper was to attempt to explain and to understand the causes of various types of eating disorders. The intention of the essay was to examine who are the different parties acting in this particular field that through research or other kinds of work, come to meet individuals that suffer from some kind of eating disorder. The aim was to explore the different concepts used wi

The primary rule of absolute duty to prosecute is stated in 20:6 RB. This means that the prosecutor is obliged to engage prosecution when there is sufficient evidence for a conviction. The possibility of waiver of prosecution is stated in 20:7 RB and is an exception from the absolute duty of prosecution. The prosecutor can decide to waive prosecution for minor offense not resulting in any other pe

This thesis assess three different conditional variance models from the GARCH family - GARCH(1,1), EGARCH(1,1) and GJR-GARCH(1,1) - and their accuracy in making one-day forecasts together with Value at Risk. The study is made on the daily returns of the OMX Stockholm 30 index between 2002-01-01 and 2010- 12-31. A five year in-sample set was used to estimate the model parameters and to make one-day
