A simple modification converts an electrospray ion source to an ambient-pressure helium plasma ionization source without the need of additional expensive hardware. Peaks for active ingredients were observed in the spectra recorded from intact pharmaceutical tablets placed in this source. A flow of heated nitrogen was used to thermally desorb analytes to gas phase. The desorption temperatures we...

Lipopolysaccharide (LPS) expressed by isolates of Pseudomonas aeruginosa from cystic fibrosis patients lacks the O-polysaccharide chain but the degree to which the rest of the molecule changes has not been determined. We analyzed, for the first time, the core structure of an LPS from a rough, cystic fibrosis isolate of P. aeruginosa. The products of mild acid hydrolysis and strong alkaline degr...

human errors are one of the most important causes of accidents. because time limitation is the most effecting factor in human errors, the likelihood of these errors in emergencies’ is higher than normal conditions. this study was aimed to manage and evaluate human errors in a case of fire in a manufacturing company. in this study human error prediction index (hepi) was used in order to evaluate...

I loved science and maths at school, which led to an undergraduate degree in physics. Through a final-year project was introduced the biosciences. From undertaking this first research getting publication from it, hooked – especially on understanding how structure of macromolecules linked their function.I had typical academic career but very different institutions Open University, Stanford Unive...
