  1. 1. Computational and Experimental Models for the Prediction of Intestinal Drug Solubility and Absorption

    Author : Christel A. S. Bergström; Per Artursson; Han van de Waterbeemd; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; aqueous drug solubility; melting point; intestinal drug permeability; pH-dependent solubility; multivariate data analysis; molecular descriptors; molecular surface area; in silico modeling; drug absorption; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

    Abstract : New effective experimental techniques in medicinal chemistry and pharmacology have resulted in a vast increase in the number of pharmacologically interesting compounds. However, the number of new drugs undergoing clinical trial has not augmented at the same pace, which in part has been attributed to poor absorption of the compounds. READ MORE

  2. 2. Macroalgae in the Baltic Sea : responses to low salinity and nutrient enrichment in Ceramium and Fucus

    Author : Lena Bergström; Lars Ericson; Lena Kautsky; Erik Bonsdorff; Christine A Maggs; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; adaptation; asexual reproduction; Baltic Sea; Gulf of Bothnia; salinity; macroalgae; nutrients; sexual reproduction; stress; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Abstract : The brackish Baltic Sea is a marginal environment for both marine and freshwater species. The rate of ecological differentiation is presumably high due to strong selection pressure from a gradient of decreasing salinity that has been present in its current state for only about 3 000 years.

  3. 3. Synthesis of Mesoporous Silica and their Use as Templates for Metal and Metal Oxide Nanoparticles

    Author : Mohamed A. Ballem; Magnus Odén; José M. Córdoba; Fredrik Söderlind; Lennart Bergström; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This thesis covers the synthesis and characterization of two types of mesoporous silica, SBA-15 silica with two-dimensional hexagonal arrangement, and SBA-16 silica with three-dimensional cubic arrangement. The obtained mesoporous materials were then used as hard templates for synthesizing of different types of nanostructures. READ MORE

  4. 4. Temporality and the Semantics of the Biblical Hebrew Verbal System

    Author : Ulf Bergström; Göran Eidevall; Sören Holst; John A. Cook; Uppsala universitet; []
    Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Biblical Hebrew; semantics; temporality; verb; aspect; tense; progressive; resultative; semiotics; Old Testament Exegesis; Gamla testamentets exegetik;

    Abstract : This dissertation investigates the semantic factors behind the temporal meanings of the Biblical Hebrew (BH) verbal forms. Four different forms are studied, viz. qotel, yiqtol-L, qatal, and yiqtol-S. READ MORE

  5. 5. Oviposition strategies in butterflies and consequences for conservation

    Author : Anders Bergström; Sören Nylin; Jeremy A. Thomas; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : Oviposition strategies are an important component of life history evolution in insects. Oviposition is a complex behaviour, where females must locate suitable habitat patches, locate oviposition sites, evaluate the quality, and finally decide how many eggs to lay. READ MORE
