2. 1. Structures, toxicity and internalization of cell-penetrating peptides

   Author : Emelía Eiríksdóttir; Ülo Langel; Michael Gait; Stockholms universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CPP; cell-penetrating peptide; internalization; toxicity; structures; Neurochemistry; Neurokemi; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

   Abstract : Cellular internalization is a highly regulated process controlled by proteins in the plasma membrane. Large and hydrophilic compounds, in particular, face difficulties conquering the plasma membrane barrier in order to gain access to intracellular environment. This puts serious constrains on the drug industry since many drugs are hydrophilic. READ MORE

4. 2. Prediction of zinc-binding sites in proteins and efficient protein structure description and comparison

   Author : Nanjiang Shu; Sven Hovmöller; Elisabeth Sauer-Eriksson; Alexander Luybartsev; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; zinc-binding; shape strings; protein structures; secondary structures; machine learning; Molecular biology; Molekylärbiologi; Biochemistry; Biokemi; Bioinformatics; Bioinformatik; Structural biology; Strukturbiologi; Biochemistry; biokemi; strukturbiologi; Structural Biology; Molecular Biology; molekylärbiologi;

   Abstract : A large number of proteins require certain metals to stabilize their structures or to function properly. About one third of all proteins in the Protein Data Bank (PDB) contain metals and it is estimated that approximately the same proportion of all proteins are metalloproteins. READ MORE

5. 3. Secondary Metabolites from Mozambican Plants

   Author : Julião Monjane; Centrum för analys och syntes; []
   Keywords : Secondary metabolites; Mozambique; Medicinal plants; Isolation; Structural elucidation; Antileishmanial activity;

   Abstract : Products derived from different natural sources have been used for thousands of years by human beings for their everyday needs. Out of these natural sources, plants were the most affordable. Plant-derived products were used for shelter, food, and as medicines. READ MORE

6. 4. Coherent structures and control in wall-bounded turbulent flows

   Author : Marco Atzori; Philipp Schlatter; Ricardo Vinuesa; Oscar Flores; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulent boundary layers; numerical simulations; coherent structures; predetermined flow control.; Turbulenta gränsskikt; numeriska simuleringar; koherenta strukturer; förutbestämd flödeskontroll; Teknisk mekanik; Engineering Mechanics;

   Abstract : This thesis is concerned with two distinct topics related to the study of wall-bounded turbulence: the connection between instantaneous three-dimensional coherent structures and mean-flow properties, and the development and analysis of pre-determined control techniques for adverse-pressure-gradient boundary layers.We examined regions with intense velocity fluctuations in various flowcases.

7. 5. Schools in sparse spatial structures

   Author : Tommy Lind; Ulf Wiberg; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Abstract : This thesis describes and analyses how the school sector in sparsely populated municipalities in northern Sweden has developed with emphasis on spatial dimensions and in relation to demographic change and political reforms during the last 20 years.In paper I primary schools were studied in a number of small municipalities in the northern parts of Norway, Sweden, and Finland.
