PURPOSE: The study aimed to (1) optimize the radiation doses of computed tomography (CT) of paranasal sinuses, (2) compare the radiation doses of different CT protocols with that of plain radiography, and (3) evaluate the reliability of low-dose CT in the detection of pathology and characterization of the detected pathology. MATERIALS AND METHODS: A head phantom was examined with different scan pa
Knowledge has become a key source of competitiveness for advanced regions and nations, indicating a transformation of capitalism towards a "knowledge economy". Knowledge intensive sectors in production and in services have a lead in this respect, they can be considered as role models for the future. The innovation process, the mechanisms of knowledge exchange and the respective linkages in those i
Flint was the most widely employed raw material for artifact manufacture in Denmark and Sweden during the Stone Age, and it continued to be used during subsequent periods. Prehistoric flint mining and lithic manufacturing studies in these countries have attracted considerable attention, but there have been no recent attempts to chemically characterize the geologic source materials. This paper buil
Microdosing is a new concept in drug development that-if implemented in the pharmaceutical industry-would mean that new drugs can be tested earlier in humans than done today. The human microdosing concept-or 'Phase 0'-may offer improved candidate selection, reduced failure rates in the drug development line and a reduction in the use of laboratory animals in early drug development, factors which w
In December 2005, the WTO responded to the HIV/AIDS pharmaceutical crisis in the least developed world by voting to make the first permanent amendment to the WTO Agreements since their original negotiation during the Uruguay Round. New Article 31bis will amend the TRIPS Agreement to permit compulsory manufacturing licenses in order to facilitate supply of needed pharmaceuticals to those countries
Marie Belloc Lowndes was a prolific author, publishing over forty novels in addition to plays, memoirs and a large number of short stories spanning the first five decades of the twentieth century. Most of these are now largely forgotten. Despite her obvious popularity, evidenced by a significant number of film adaptations of her novels, Lowndes has not yet reached the radar of literary studies. Th
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
Stochastic optimal power flow can provide the system operator with adequate strategies for controlling the power flow to maintain secure operation under stochastic parameter variations. One limitation of stochastic optimal power flow has been that only limits on lineflows have been used as stability constraints. In many systems voltage stability and small-signal stability also play an important role i
The copper access-network operators face the challenge of developing and maintaining cost-effective digital subscriber line (DSL) services that are competitive to other broadband access technologies. The way forward is dictated by the demand of ever increasing data rates on the twisted-pair copper lines. To meet this demand, a relocation of the DSL transceivers in cabinets closer to the customers
The dissertation analyzes a recognized collective political actor in Egypt, the shabāb al-thawra – the revolutionary youth. The thesis posits that in order to understand the shabāb al-thawra political actor, it is necessary problematize “revolutionary youth” beyond its nominative sense. Instead, the concepts of “youth” and “revolutionary” are conceived as communities of practice, whereby “youth” r
It is important to know the contributions of bacteria and fungi to decomposition in connection with both the structure of the food web and the functioning of the ecosystem. However, the extent of the competition between these groups of organisms is largely unknown. The bacterial influence on fungal growth in a soil system was studied by applying three different bacterial inhibitors - bronopol, tyl
PURPOSE: To determine the incidence of associated intrinsic and extrinsic ligament injuries in patients with a nondisplaced or displaced scaphoid waist fracture. METHODS: During a 3-year period, a study of all scaphoid fractures was performed at our institution. Diagnosis was confirmed by plain radiographs, computed tomography, and magnetic resonance imaging. A 3-part anatomic classification was u
Many genes and proteins are required to carry out the processes of innate and adaptive immunity. For many studies, including systems biology, it is necessary to have a clear and comprehensive definition of the immune system, including the genes and proteins that take part in immunological processes. We have identified and cataloged a large portion of the human immunology-related genes, which we ca
