Constant time gradient HSQC-iDOSY: practical aspects

Quantitative HSQC Analyses of Lignin: A Practical Comparison

Lignin is the second-most abundant polymer after cellulose within the biomass of our planet. Structurally, it displays random oligomeric units without fixed repetition schemes beyond the stage of dimers. Quantitative (1)H-(13)C HSQC measurements have recently greatly facilitated lignin analyses. In some cases, however, long acquisition times needed for obtaining quantitative HSQCs are not compa...

Practical Aspects of Alcoholism

to no closing hours, when the yearly convictions for drunkenness touched the 200,000 mark. All the same, it is bad enough. We have a population of well over 100.000 severe alcoholics, and since alcoholism involves the dependents, half a million people at least suffer from its repercussions. One would think that the State, the Profession and the Health Service would do all they could to help. In...

Reference Intervals: Practical Aspects

Arguably, one of the most important elements of a laboratory test is the reference interval, the values that help clinicians interpret their patients’ test results. Interestingly, though, laboratorians spend surprisingly little time formally addressing the issue of reference intervals. Typically, they adopt the intervals given them by manufacturers, neither establishing the intervals themselves...

Constant adverse pressure gradient turbulent boundary layers

Significant progress has been made towards understanding the large scale features of wall-bounded shear flow in zero pressure gradient (ZPG) turbulent boundary layers (TBL). Here we consider their effects in adverse pressure gradient (APG) flows where the pressure gradient parameter is held constant and Reynolds number is varied. This is done by documenting the changes in the mean velocity, str...
