Semantic roles, logical relations such as Agent or Instrument that hold between events and their participants and circumstances, need to be determined automatically by several types of applications in natural language processing. This process is referred to as semantic role labeling. This dissertation describes how to construct statistical models for semantic role labeling of English text, and how

This is a longitudinal study of smallholder farm dynamics in eight African countries, drawing on a sample of more than 3000 farm households. It deals with influences on smallholder maize production at three different levels: micro, meso and macro. Although the study points to inadequately exploited production potentials and a production system based primarily on self-provisioning the drivers behin

This literature review is an initial part of a larger research project that deals with evacuation upwards long stairs and physical exertion. The literature review focused on identifying the current state of published knowledge regarding how physical exertion influence people when evacuating upward long stairs and if there are specific design requirements for stairs intended primarily for upward mo

Anti-phospholipid (aPL) antibodies are important contributors to development of thrombosis in patients with the autoimmune rheumatic disease systemic lupus erythematosus (SLE). The underlying mechanism of aPL antibody-mediated thrombosis is not fully understood but existing data suggest that platelets and the complement system are key components. Complement activation on platelets is seen in SLE p

Objective The purpose of this study was to evaluate the effect of wet clothing removal or the addition of a vapor barrier in shivering subjects exposed to a cold environment with only limited insulation available. Methods Volunteer subjects (n = 8) wearing wet clothing were positioned on a spineboard in a climatic chamber (–18.5°C) and subjected to an initial 20 minutes of cooling followed by 3

Atlantic salmon accumulate high levels of contaminants such as polychlorinated biphenyls (PCBs) in their lipids during the adult growth phase spent at sea. The lipids are later utilized during migration for swimming and biological adaptations. We hypothesize that migrating salmons' biotransformation processes are affected by the high levels of built-up PCBs compared to salmon that in a pre-migrati

Invasive cancer causes a change in density in the affected tissue, which can be visualized by x-ray phase-contrast tomography. However, the diagnostic value of this method has so far not been investigated in detail. Therefore, the purpose of this study was, in a blinded manner, to investigate whether malignancy could be revealed by non-invasive x-ray phase-contrast tomography in lymph nodes from b

High-energy synchrotron X-ray diffraction offers the unique combination of high spatial resolution and bulk material penetration power, which is well suited for the investigation of strain fields around cracks in engineering materials. The speed of data acquisition also lends itself to the observation of in-situ processes, such as crack propagation. This potential has been only partially explored

The Gaia space astrometry mission (to be launched in 2012) will use a continuously spinning spacecraft to construct a global system of positions, proper motions and absolute parallaxes from relative position measurements made in an astrometric focal plane. This astrometric reduction can be cast as a classical least-squares problem, and the adopted baseline method for its solution uses a simple ite

The construction of the European Spoliation Source (ESS) faces many challenges from the neutron beam transport point of view: the spoliation source is specified as being driven by a 5 MW beam of protons, each with 2 GeV energy, and yet the requirements in instrument background suppression relative to measured signal vary between 10(-6) and 10(-8). The energetic particles, particularly above 20 MeV

Aims To determine current management and to identify patient-related factors and barriers that influence management strategies in diabetic foot disease. Methods The Eurodiale Study is a prospective cohort study of 1232 consecutive individuals presenting with a new diabetic foot ulcer in 14 centres across Europe. We determined the use of management strategies: referral, use of offloading, vascular

Linear pi-conjugated oligomers have been widely investigated, but the behavior of the corresponding cyclic oligomers is poorly understood, despite the recent synthesis of pi-conjugated macrocycles such as [n]cycloparaphenylenes and cyclo[n]thiophenes. Here we present an efficient template-directed synthesis of a pi-conjugated butadiyne-linked cyclic porphyrin hexamer directly from the monomer. Sma
