Popular Abstract in Swedish Runt 1750 upptäckte en tysk kemist vid namn Marggraf att det var möjligt att utvinna socker från betor. Ett par decennier senare började en av hans studenter, Archard, att selektera betor utifrån deras sockerhalt och öppnade också världens första sockerbetsfabrik år 1801. Mängden utvunnet socker per rot låg runt 4 %. Sedan dess har förädling och förbättrade jordbruksmetAround 1750 a German chemist discovered it to be possible to extract sugar crystals from beet juice. Since then, breeding and improved agricultural practices have increased the concentration of sucrose per root from around 4% to around 18%. Sugar content is still one of the most important characters in sugar beet breeding, but breeders of today are also faced with many more characters, many of a c

The establishment of e-businesses has often been implemented from the inside of companies rather than from the customer perspective and the knowledge about customer needs from traditional businesses have been applied directly into new e-business systems. The overall objective of this study is to identify how to better understand customer needs and how to integrate these needs in order to create cu

A network model has been formulated and used for computer simulations of the geometry an mechanical behaviour of cellulose fibre networks. The focus is on the properties needed to proceed with a continuum analysis of fracture, that is stiffness, strength and fracture energy. It is found that the ductility of inter-fibre bonds has a strong effect on the fracture properties. Localization of the frac

The detection of microorganisms by PCR can be divided into four steps: (1) sample collection, (2) sample preparation, (3) DNA amplification and (4) detection of PCR products. The major problem in developing PCR-based detection methods is the sample preparation step. This step is necessary to overcome problems caused by PCR inhibitors and it determines, to a large extent, the sensitivity of the PCR

Popular Abstract in Swedish Pankreascancer (cancer i bukspottkörteln) drabbar årligen mer än 200 000 personer över hela världen, varav omkring 900 i Sverige. Sjukdomen är starkt associerad till ökad ålder och drabbar följaktligen väldigt sällan personer under 40 år, medan risken att drabbas vid 80 års ålder är 40 gånger förhöjd. På grund av dess mycket aggressiva tillväxt, tidiga metastasering samPancreatic cancer includes multiple histologic subtypes that show large differences in their clinical and biological characteristics. Despite this diversity, more than 85% of the neoplasms in the organ are malignant ductal adenocarcinomas, which are the focus of the present thesis. At the genetic level this tumor type is characterized by highly rearranged karyotypes, resulting in a large number of

A core-excited I = (12+) spin-gap isomer was identified in 98Cd in an experiment at EUROBALL IV. It was found to feed the known I = (8+) seniority isomer by an E4 transition. Half-lives of T1/2 = 0.23() µs and 0.17() µs were measured for the two states at Ex = 6635 keV and 2428 keV, respectively. From the excitation energy of the core-excited isomer a 100Sn shell gap of 6.46(15) MeV is inferred. T
