Carbon Nanotube Emissions from Arc Discharge Production: Classification of Particle Types with Electron Microscopy and Comparison with Direct Reading Techniques.

Introduction: An increased production and use of carbon nanotubes (CNTs) is occurring worldwide. In parallel, a growing concern is emerging on the adverse effects the unintentional inhalation of CNTs can have on humans. There is currently a debate regarding which exposure metrics and measurement strategies are the most relevant to investigate workplace exposures to CNTs. This study investigated wo

Pulmonary dysfunction, smoking, socioeconomic status and the risk of developing rheumatoid arthritis.

Objectives. Environmental risk factors are of potential interest for both prevention and treatment of RA. The purpose of this study was to examine the effect of pulmonary function, smoking and socio-economic status on the future risk of RA. Methods. Between 1974 and 1992, 22 444 men and 10 902 women were included in the Malmö Preventive Medicine Program (MPMP). Pulmonary function was assessed by a

Agrarian plant economy at Uppåkra and the surrounding area : Archaeobotanical studies of an Iron Age regional center

Up until the late nineteenth and early twentieth century, and probably since the introduction of agriculture to Sweden, the social life, culture, traditions, building patterns and material culture would largely have been based on agricultural practices. And yet, in the archaeological record, agricultural aspects of social life remain elusive and little is known about the organization of farming an

Cyclophilin D-sensitive mitochondrial permeability transition in adult human brain and liver mitochondria.

The mitochondrial permeability transition (mPT) is considered to be a major cause of cell death under a variety of pathophysiological conditions of the CNS and other organs. Pharmacological inhibition or genetic knock-out of the matrix protein cyclophilin D (CypD) prevents mPT and cell degeneration in several models of brain injury. Provided that findings in animal models can be translatable to hu

The Decline and Fall of the Church : The Middle Ages, the Gothicization, and the Reformation

Summary and further discussion of the main thesis in the authors dissertation (Den gotiske labyrint. Middelalderen og kirkerne i Danmark; The Gothic labyrinth. The Middle Ages and the churches in Denmark, 1993). Monasteries in Denmark, their forundation dates, numbers, size, design, decoration and fixtures are used as a source to show when the power of the church was built up, changed and broken d

The force of the argument

In reply to Wiklund (2009), this paper addresses once again embedded V2 clauses in Scandinavian: the behaviour of certain discourse oriented elements in these clauses, the possibility of topicalising embedded V2 clauses, and the optionality of embedded V2. The conclusion is that the analysis according to which embedded V2 clauses have illocutionary force can still be maintained.

Direct Numerical Simulations of Low Temperature Combustion in IC Engine Related Conditions

Popular Abstract in English Internal combustion engine plays an important role in our society. In our daily life, we use them to drive cars, trucks, ships, generating electricity and heat, and in many other applications. Modern internal combustion engines fall into three catalogues: gasoline engines, diesel engines and low temperature compression ignition engine. They are developed to achieve highThis thesis deals with direct numerical simulation (DNS) of low temperature combustion in internal combustion engine related conditions. In particular, HCCI (homogeneous charge compression ignition), SACI (spark assisted ho-mogeneous charge compression ignition) and PPC (partially premixed charge combustion) were investigated to gain deeper understanding on the details of the combustion process. I

On Bicompositional Correlation

A composition is a vector of positive components summing to a constant, usually taken to be 1. Hitherto the research on compositional correlation has mainly focused on the correlation between the components of composition. This thesis is concerned with modelling the correlation between two compositions. We introduce a generalization of the Dirichlet distribution to simultaneously describe two co

Initiation of acute pancreatitis by heparan sulphate in the rat.

OBJECTIVE: The initiating events in the onset of pancreatitis are poorly understood. Possible candidates may be endogenous ligands, acting on receptors within ductal, acinar or stellate cells, which have previously been shown to cause a systemic inflammatory response syndrome. The aim of this study was to investigate whether acute pancreatitis could be induced by heparan sulphate (HS)infused into
