  1. 1. Studies towards a method for incorporation of 3'-deoxy-3'-C-methylenephosphonate linkages into oligonucleotides

    Author : Anna Winqvist; Colin B. Reese; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic Chemistry; organisk kemi;

    Abstract : Synthetic strategies towards 3’-deoxy-3’-C-methylenephosphinate building blocks were explored. The key transformations involved stereoselective hydroboration of 1-[2-O-(tert-butyldimethylsilyl-5-O-(4-methoxytrityl)-3-deoxy-3-C-methylene- ß -D-erythro-pentofuranosyl]uracil to give the corresponding 3’-deoxy-3’-C- hydroxymethyl derivative with ribo-configuration, as well as the further conversion into a precursor with a suitable leaving group, e.

  3. 3. Synthesis of Nitrogen Heterocycles via 1,3-Dipolar Cycloadditions - Method Development and Applications

    Author : Johan Johansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 2D NOESY; alkyne; 3-dipolar cycloaddition; azomethine ylide; 1; CNTs; azide; sequential one-pot; SEM EDS; microwave heating; RuAAC; CuAAC;

    Abstract : Because of the diverse properties displayed by nitrogen heterocycles, they are one of the most commonly used structural elements in drug discovery. Due to this variation in properties, however, the chemistry and synthetic pathway to each heterocycle is unique. READ MORE

  4. 4. Direction of Arrival Estimation and Localization of Multiple Speech Sources in Enclosed Environments

    Author : Mikael Swartling; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Beamforming; Detection and classification; Speech enhancement; Source localization;

    Abstract : Speech communication is gaining in popularity in many different contexts as technology evolves. With the introduction of mobile electronic devices such as cell phones and laptops, and fixed electronic devices such as video and teleconferencing systems, more people are communicating which leads to an increasing demand for new services and better speech quality.

  5. 5. Understanding and supporting requirements engineering decisions in market-driven software product development

    Author : Nina Dzamashvili-Fogelström; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Context: Requirements engineering (RE) for software products offered to a mass market is concerned with deciding which of the diverse and large amounts of potential requirements to implement into future releases of a product. While being the key for achieving success, these decisions are very complex. READ MORE
