Automatic knowledge discovery from texts (KDT) is proving to be a promising method for businesses today to deal with the overload of textual information. In this paper, we first explore the possibilities for KDT to enhance communication in virtual communities, and then we present a practical case study with real-life Internet data. The problem in the case study is to manage the very successful vir

A hypothesis regarding the mechanism causing salt frost scaling on Portland cement-bound materials is described. It is assumed that deterioration is due to osmotic micro ice body growth, as has been previously proposed for frost deterioration of moisture-isolated specimens of cement-bound materials. In moisture-isolated specimens, this ice body growth stops when the micro structure is drained to a

Purpose: We analyzed a large group of patients with hypospadias regarding familial aggregation, phenotype, twin rate and ethnic origin and assessed the correlation of low birth weight with hypospadias. Materials and Methods: We mailed questionnaires to 2,503 boys operated on for hypospadias in Sweden asking for additional cases of hypospadias in the family, the number of brothers in the nuclear fa

Purpose: We investigated the value of serum measurements for glandular kallikrein 2 (hK2), and free (f) and total (t) prostate specific antigen (PSA) in a second round of biannual screening for prostate cancer. Materials and Methods: In 1995 to 1996, 5,853 of 9,811 randomly selected men in Goteborg, Sweden 50 to 66 years old had PSA measurements. Of 660 men 611 with tPSA 3 ng/ml or greater underwe

Background: In the Malmö Diet and Cancer study, information on dietary habits was obtained through a modified diet history method, combining a 7-day menu book for cooked meals and a diet questionnaire for foods with low day-to-day variation. Half way through the baseline data collection, a change of interview routines was implemented in order to reduce interview time. Methods: Changes concentrated

Popular Abstract in Swedish Inom svensk hälso- och sjukvård är 82% av samtliga landstingsanställda kvinnor. Majoriteten av dessa kvinnor återfinns in organisationsstrukturens mellanskikt eller bas. I denna avhandling problematiseras den process inom vilken maktutövning sker i vardagliga möten mellan kvinnor och män inom tre somatiska vårdavdelningar. Resultatet visar att den genusrelaterade maktutThe primary aim of the present thesis is to increase understandig of the relationship between organisational structure, gender and power. Understanding of this relationship requires a closeness to the individual being studied as well to the content and consequences of that individuals´actions. The empirical object of study is a group of professional women at a somatic clinic. The problem investiga

Mercury emission measurements from the ldrija mercury mine in Slovenia were performed during an early November 2003 campaign, where the differential lidar technique was used to map mercury concentrations and an attempt was made to quantify the total mercury flux from the most contaminated area, the abandoned cinnabar roasting oven complex. Lidar concentration data were compared with data recorded

In this paper concepts and nomenclature of light measurements are discussed. The particular problems of underwater light measurements and the calibration of the equipment were presented. The pros and cons with spectroradiometers and broad band sensors were discussed. The use of specific ultraviolet-B sources for algal photobiology is recommended.

in this study, metal-free phthalocyanine has been deposited on a conducting glass surface by two methods: by spreading the molecular powder directly on the substrate in air and by vapor sublimation under ultra-high vacuum conditions (evaporation). The films have been characterized by means of core level X-ray Photoemission Spectroscopy, X-ray Absorption Spectroscopy (XAS) and Ultra Violet and Visi

Objective: The association between consumption of fruit and vegetables and risk of ovarian cancer is still unclear from a prospective point of view. Methods: Female participants (n = 325,640) of the European Prospective Investigation into Cancer and Nutrition study, free of any cancer at baseline, were followed on average for 6.3 years to develop ovarian cancer. During 2,049,346 person-years, 581

he study focuses on two elicitation methods for language sampling in children with language impairment: conversation and narration. It has been noted in other studies on different clinical groups that language elicited in different speaking contexts varies in aspects such as MLU, fluency and syntactic complexity. The purpose of this study was to compare genre effects on different aspects of langua

The X-linked form of Alport syndrome (AS) is caused by mutation in the COL4A5 gene located at Xq22.3 and encoding the alpha 5-chain of type IV-collagen. More than 400 different mutations have so far been detected in the COL4A5 gene. Not all mutations, however, will be detected using an exon-by-exon mutation detection strategy such as SSCP analysis or direct sequencing. We have previously reported

The roles of intracellular Ca2+ stores and ryanodine (Ry) receptors for vascular Ca2+ homeostasis and viability were investigated in rat tail arterial segments kept in organ culture with Ry (10 100 M) for up to 4 days. Acute exposure to Ry or the non-deactivating ryanodine analogue C10-Oeq glycyl ryanodine (10 M) eliminated Ca2+ release responses to caffeine (20 mM) and noradrenaline (NA, 10 M), w

The Eu(III)-coordination of phenyltrisalanine (Pta) 1, in aqueous solution was investigated. The photoluminescence data suggested that the chelating effect of Pta places the metal ion on the face of the aromatic ring as proposed in 4. Furthermore, Eu(III) is usually used as a substitute for Ca(II) in spectroscopic studies and the formation of a 1:1 complex between Pta and Eu(III) indicated the pos
