CRISPR3 Regulates Exopolysaccharide Production in Myxococcus xanthus
… Repeats (CRISPR) on its chromosome. CRISPR systems, which function as an adaptive immune system in prokaryotes, are classified into three types based on CRISPR-associated genes. Evidence suggests that these three types mediate immunity slightly differently. M. xanthus CRISPR1 and CRISPR2 are …

Anaerobic / Aerobic Digestion for Enhanced Solids and Nitrogen Removal
… of nitrogen was observed. The An/Aer/An – B system had more ammonia and TKN removal (70%) than Ana/Aer (64%). The effluent from each stage was analyzed for dewatering ability, cake solid concentration and odor production potential. Compared with a single Ana/Aer system, the extra anaerobic …

Colour analysis and the classification of fruit
… a time as possible. This thesis describes colour systems and methods to grade the fruit automatically via the clustering and classification methods. After investigating several approaches to automatically sort fruit based on colour, an image processing approach was taken. The colours on the fruit …

Characterization and application of type VI-B RNA-targeting CRISPR systems
… DNA nucleases derived from class 2 CRISPR systems, which provide adaptive immunity in prokaryotes through cleavage of nucleic acids using a single, multi-domain, RNA-guided endonuclease, have been particularly useful in this regard because they enable targeting of new sites through simple …

A systems analysis of sweet sorghum harvest for a Piedmont ethanol industry
The Piedmont System is a collection of equipment for efficiently removing the juice from sweet sorghum stalks for the production of ethanol. The concept is to separate the whole stalks into pith and rind-leaf fractions, pass only the pith fraction through a screw press, and thus achieve an …
