a bstra ct background: annually, about 6000 new cases are diagnosed with breast cancer in iran. in iran, more women are affected with breast cancer than a decade earlier in comparison with other countries, and 70% of them are diagnosed at an advanced phase. insomnia is the most common disorder following breast cancer, and interference in sleep quality and rest causes changes in physiological fu...

this paper is devoted to the study of determining optimal process mean in system production with the two markets for the sale of goods. in this paper, we developed an absorbing markov chain model in production systems where all items are inspected %100 for conformance with their specification limits. when the value of the quality characteristic of an item falls below a lower limit, the item is ...

in this research, a new control policy for the acceptance sampling problem is introduced. decision is made based on the number of defectives items in an inspected batch. the objective of the model is to find a constant control level that minimizes the total costs, including the cost of rejecting the batch, the cost of inspection and the cost of defective items. the optimization is performed by ...

asthma control and quality of life are expected to be correlated. we aimed to evaluate the association of asthma control test (act) with asthma quality of life questionnaire (aqlq) and guideline based control assessment. we also aimed to investigate the impact of therapy adjustment according to act score on aqlq a total of 101 asthmatic patients were included. act, aqlq and global initiative fo...

background: quality assurance in the hematology laboratory is a must to ensure laboratory users of reliable test results with high degree of precision and accuracy. even after so many advances in hematology laboratory practice, pre-analytical errors remain a challenge for practicing pathologists. this study was undertaken with an objective to evaluate the types and frequency of preanalytical er...

with the following parameter changes: Sample volume 40 pipetting 2.0 mL of FFP into the calcium-adulterated ACT 4; Diluent volume 14 L; Calculation mode 0. When tube, and treat it as if it were a patient’s sample. modified as above, results are reported in milligrams per The precision ofthe FFP and AP’N’ systems is tabulated liter and cover the range 1.7-54.5 mg ofalbunun per liter. below: We a...

Quantitative qPCR is a routinely used method for the accurate quantification of nucleic acids. Yet it may generate erroneous results if the amplification process is obscured by inhibition or generation of aberrant side-products such as primer dimers. Several methods have been established to control for pre-processing performance that rely on the introduction of a co-amplified reference sequence...

Stochastic models are developed in this article to examine the rate of test misgrading in educational and psychological measurement. The estimation of inadvertent grading errors can serve as a basis for quality control in measurement. Limitations of traditional Poisson models have been reviewed to highlight the need to introduce new models using well established geometric and negative binomial ...

Standard reference strains of Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa were suspended in sterile deionized water and tested daily via disk agar diffusion for their antimicrobial susceptibilities. Inocula of E. coli and P. aeruginosa yielded acceptable results for up to 32 days; however, results on S. aureus were unacceptable due to loss of viability of the organism in...
