High Volume Sampling: Errors Incurred during Passive Sample Exposure Periods

The Effect of Measurement Errors on the Performance of Variable Sample Size and Sampling Interval Control Chart

The effect of measurement errors on adaptive and non-adaptive control charts has been occasionally considered by researchers throughout the years. However, that effect on the variable sample size and sampling interval (VSSI) control charts has not so far been investigated. In this paper, we evaluate the effect of measurement errors on the VSSI control charts. After a model development, the effe...

Passive cigarette smoke exposure during various periods of life, genetic variants, and breast cancer risk among never smokers.

The association between passive cigarette smoke exposure and breast cancer risk is inconclusive and may be modified by genotype. The authors investigated lifetime passive cigarette smoke exposures, 36 variants in 12 carcinogen-metabolizing genes, and breast cancer risk among Ontario, Canada, women who had never smoked (2003-2004). DNA (saliva) was available for 920 breast cancer cases and 960 c...

Economical Design of Double Variables Acceptance Sampling With Inspection Errors

The paper presents an economical model for double variable acceptance sampling with inspection errors. Taguchi cost function is used as acceptance cost while quality specification functions are normal with known variance. An optimization model is developed for double variables acceptance sampling scheme at the presence of inspection errors with either constant or monotone value functions. The m...

Acute bronchospasm during passive exposure to bronchial provocation tests.

Bronchial challenge with direct stimuli, like histamine and methacholine, is very sensitive for diagnosing asthma and produces similar responses on a milligram-on-milligram or on a millimole-on-millimole basis [1–4]. American Thoracic Society (ATS)/European Respiratory Society (ERS) guidelines have proposed measures in order to protect technicians performing these tests, which include the use o...
