In this paper we propose that the foraging behavior of benthic fish can be used to assess the current state of shallow lake ecosystems. Shallow lakes may display shifts between clear and turbid states, where sediment resuspension by benthivores foraging on benthic invertebrates contributes to maintaining the turbid state. We suggest that the giving-up density (GUD) of benthic fish foraging in expe

Aim: Results from several studies indicate that the total homocysteine (tHcy) concentration in plasma is an independent risk factor for cardiovascular disease in hemodialysis patients. Folic acid is the established mainstay of homocysteine-lowering treatment, but since such treatment does not normalize plasma tHcy concentration in hemodialysis patients, it is of importance to search for additional

In a retrospective study of 213 patients with high-grade non-Hodgkin's lymphomas clinical stage I, diagnosed 1985-1990, pretreatment prognostic variables and result of treatment were analysed. The median age of the patients was 67 years. Treatment consisted of radiotherapy in 61%, chemotherapy (10%) chemotherapy followed by radiotherapy (23%) and surgery alone (5%) of the patients. Complete respon

Adaptation of a xylose-utilizing genetically engineered strain of Saccharomyces cerevisiae to sugarcane bagasse hydrolysates by cultivation during 353 h using medium with increasing concentrations of inhibitors, including phenolic compounds, furaldehydes and aliphatic acids, led to improved performance with respect to ethanol production. The remaining xylose concentration in the medium at the end

Att gå i skolan är fullkomligt normalt. Förmodligen är det ett av skälen till att utbildningsforskningen sällan frågar vad det betyder att varje person i vårt samhälle tvingas tillbringa nio år i den obligatoriska skolan. Betydligt vanligare är det att fråga vad, hur och varför eleverna lär sig i skolan. Intresset för skoltidens innehåll är helt enkelt större än för skoltiden som sådan. Skoltidens

Undisplaced radial head and neck fractures are consistently described with no long-term deficits. The aim of this study was to evaluate specifically the long-term outcome of displaced Mason type I fractures, which have not previously described. Twenty women and twelve men, with a mean age of 46 years (range, 22-69 years) when they sustained a displaced Mason type I fracture, were reexamined at a m

Most companies and testing books use the term unit testing, but its semantics varies widely in different organizations. Lund University researchers launched a survey in 19 companies to explore variations in the term. The results indicate a common understanding of the scope of unit testing, although its aim and practices vary across companies. Practitioners can use the survey instruments as a basel

Popular Abstract in Swedish Studien presenterar en relationell ansats till förhandlingar, dvs en förhandlingsanalys i vilken relationerna mellan aktörerna står i centrum. Det innebär att istället för att se till enskilda förhandlares strategier etc, läggs tonvikten vid att förstå interaktionen mellan förhandlarna. Således har studier som söker slå fast nationella särdrag eller kulturellt betingadeThis study proposes the relational approach to negotiations to further our understanding of the negotiation relationship. At the center is negotiators' outlook on the other and themselves in East-West cooperation projects. This approach to negotiations is pluralist. Consequently, a number of theories have been utilized. First, using feminist theorizing in philosophy and International Relations, th

Although trisomy 8 as a sole change is one of the most common chromosomal abnormalities in myeloid malignancies, it is largely unknown if the incidence of this aberration is influenced by other factors of clinical importance. In the present study, the frequencies of isolated +8 in relation to gender, age, previous treatment with chemo- or radiotherapy, and morphologic subtype were ascertained in p
