  • A series of trehalose-based oligosaccharides were isolated from the cytoplasmic fraction of Mycobacterium smegmatis and purified by gel-filtration and paper chromatography and TLC. Their structures were determined by HPLC and GLC to determine sugar composition and ratios, MALDI-TOF MS to measure molecular mass, methylation analysis to determine linkages, 1H-NMR to obtain anomeric configurations of glycosidic linkages, and exoglycosidase digestions followed by TLC to determine sequences and anomeric configurations of the monosaccharides....

  • The Mycobacterium tuberculosisgenome contains an unusually high number of proteins involved in the metabo-lism of lipids belonging to the Lip family, including various nonlipolytic and lipolytic hydrolases. Driven by a structural genomic approach, we have biochemically characterized the Rv1399c gene product, LipH, previously annotated as a putative lipase. Rv1399c was overexpressed inE. colias inclusion bodies and refolded. Rv1399c efficiently hydro-lyzes soluble triacylglycerols and vinyl esters.

  • · Select an institution to carry out the initial accounting work. While in the long run environmental accounts are likely to come under the purview of those responsible for national accounting, often those groups are unwilling to initiate the work because it is perceived as too experimental. Instead, initial work may be carried out by environment departments, government-affiliated research groups, or other players who have a strong stake in the outcome but take less risk by putting their name on experimental work.

  • Direct users of the information Apheis produces and disseminates include the scientists who appear just to the right of the Apheis box and who receive information directly from Apheis. These scientists in turn pass that information on to other scientists and to committees, seen in the box further to the right, all of whom thus become pass-on users, because they receive the information Apheis produces indirectly from Apheis. Then, the individual scientists and committees pass Apheis information on to the policy advisors below them, who form another group of pass-on users.

  • So, in summary, traction is important for transmitting the forces from the wheels to the road. If any of your wheels are spinning rather than rolling, you probably need more traction. Traction can be increased by adding a non-slip material around the wheels (like a tire) or by moving weight over the driven wheels. But, remember, it is also important to have efficient wheels, which are usually thin and lightweight. Bearings When you have two things rubbing against each other and you want them to move freely, friction slows things down and wastes energy.

When Jobs introduced the iPod in 2001, he said, “In our own small way, we’re going to make the world a better place.” Where most people saw the iPod as a music player, Jobs saw it as tool to enrich people’s lives. Of course, it was important to have great products. But passion, enthusiasm and a sense of purpose beyond the actual product are what set Jobs and Apple apart. Jobs was also...

  • The first bronze, Marie, 1982, was made by wrapping plaster soaked burlap around itself to form an elongated, cigar-shaped mass. There are no preparatory sketches or models which are then enlarged. Since scale and spontaneity are of central importance a model can have no place in the creation of the sculptures. “I make things the size the are”. The methodology of the first sculptures is a direct extension of Schnabel’s wish to produce a shape as the result of a process rather than as the rendering of a precise vision in his head....
