The structure of the semenogelin gene locus--nucleotide sequence of the intergenic and the flanking DNA

The sequence of 15.7 kb from the human semenogelin gene locus has been determined. Together with previously published sequences, this gives the structure of a 28-kb region encompassing the two semenogelin genes. The two transcription units are separated by 11616 bp intergenic DNA comprising more than 40% repetitive DNA sequences, predominantly located to a 4-kb block of L1 and Alu repeats. Two mor

Generation of synthesis gas for fuels and chemicals production

Popular Abstract in Swedish Dagens samhälle är mycket beroende av fordonsbränslen och kemikalier som producerats av råolja. Framtidens tillgång på råolja är oviss, det enda som är säkert är att det är en ändlig resurs. Användningen av olja bidrar dessutom till koldioxidutsläpp till atmosfären. För att säkra framtida tillförsel av energi och kemikalier till samhället och för att uppnå ett mer klimaMany scientists believe that the oil production will peak in the near future, if the peak has not already occurred. Peak oil theories and uncertain future oil deliveries have stimulated interest in alternative sources of fuel and chemicals. This interest has been enhanced by concerns about energy security and about the climate change caused by emissions of carbon dioxide. The result has been incre

Low Power Unrolled CORDIC Architectures

This paper shows a novel methodology to improve unrolled CORDIC architectures. The methodology is based on removing adder stages starting from the first stage. As an example, a 19-stage CORDIC is used but the methodology is applicable on CORDICs with an arbitrary number of stages. The CORDIC is implemented, simulated, and synthesized into hardware. In the paper, the performance is shown to be incr

Using Students as Experiment Subjects – An Analysis on Graduate and Freshmen Student Data

The question whether students can be used as subjects in software engineering experiments is debated. In order to investigate the feasibility of using students as subjects, a study is conducted in the context of the Personal Software Process (PSP) in which the performance of freshmen students and graduate students are compared and also related to another study in an industrial setting. The hypothe
