Measurement accuracy
No instrument can be guaranteed to give readings that are absolutely accurate every time or exactly the same as another apparently identical instrument. Several factors influence the ability of an instrument to make and display a measurement. Before we look at sources of error during a measurement, it is important to understand the limitations of an instrument and how they affect the ...

Improvement of olfactometric measurement accuracy and repeatability by optimization of panel selection procedures
The EN 13725:2003, which standardizes the determination of odour concentration by dynamic olfactometry, fixes the limits for panel selection in terms of individual threshold towards a reference gas (n-butanol in nitrogen) and of standard deviation of the responses. Nonetheless, laboratories have some degrees of freedom in developing their own procedures for panel selection and evaluation. Most ...

Production of biodiesel from pentaclethra macrophylla seed oil
In the present work, the potentials of pentaclethra macrophylla (Africa oil bean) seed oil (PMSO) are evaluated for the first time as a feedstock for biodiesel. Methyl (PMFAME) and ethyl (PMFAEE) esters of PMSO were produced by standard transesterification procedure using potassium hydroxide (KOH) as catalyst and their qualities determined. Gas chromatography mass spectrometry (GCMS) runs of the ...

Comparison of single-stage and a two-stage vertical flow constructed wetland systems for different load scenarios
Constructed wetlands (CWs) are known to be robust wastewater treatment systems and are therefore very suitable for small villages and single households. When nitrification is required, vertical flow (VF) CWs are widely used. This contribution compares the behaviour and treatment efficiencies of a single-stage VF CW and a two-stage VF CW system under varying operating and loading conditions ...
