Before quality control techniques and protocols can be applied to a laboratory procedure, the quality itself must be evaluated. This involves among other considerations an assessment of analytical accuracy. Some, but not all (and perhaps not even many), clinical laboratory analytical procedures can be considered accurate in the sense that every laboratory should get the same quantitative result...

Understanding of linkage disequilibrium (LD) in human populations could facilitate the discovery of genes that influence complex human diseases. The "HapMap" project is now underway to characterize patterns of LD in the human genome. A pilot study showed "haplotype blocks" in 51 regions scattered throughout the genome. These intriguing results raise important questions about the nature of recom...

OBJECTIVE To systematically review guidance documents for the estimation of the social cost of illegal drugs, and to define standards for this estimation. METHOD A systematic literature search was conducted between April and May 2015 and updated in November 2015. Pubmed, Scopus, and Google Scholar were searched. Studies were included only if they provided indications of analytical methods for...

This study develops a model for selecting Korean dramas based on TV station manager’s perceptions. First, the proposed model adopts the modified Delphi method to find out the suitable evaluative criteria of Korean dramas. Next, the model apply the analytic hierarchy process (AHP) to determine the relative weights of evaluative criteria, then ranks the alternatives and selects the best Korean dr...

The model-based image reconstruction approaches in photoacoustic tomography have a distinct advantage compared to traditional analytical methods for cases where limited data is available. These methods typically deploy Tikhonov based regularization scheme to reconstruct the initial pressure from the boundary acoustic data. The model-resolution for these cases represents the blur induced by the ...

Laboratories may use different analytical methods that may not be harmonized, possibly with different units of reporting. We should not assume that the differing numbers can be directly compared especially if the transfer of results from the laboratory to the report recipient does not highlight differences in units of reporting or in assay methods in use. To Corresponding author: Jillian R. Tat...

In many sliding systems consisting of solid object on a solid substrate under dry condition, the friction force does not depend on the apparent contact area and is proportional to the loading force. This behaviour is called Amontons' law and indicates that the friction coefficient, or the ratio of the friction force to the loading force, is constant. Here, however, using numerical and analytica...

Solid-Phase Extraction (SPE) is a sample preparation method that is practised on numerous application fields due to its many advantages compared to other traditional methods. SPE was invented as an alternative to liquid/liquid extraction and eliminated multiple disadvantages, such as usage of large amount of solvent, extended operation time/procedure steps, potential sources of error, and high ...
