Camphor-10-sulfonic acid (CSA)1 is routinely used for calibrating circular dichroism (CD) instruments. However, CSA is hygroscopic, so an accurate concentration can be obtained only by measuring its absorbance peak at 285nm. Hence, calibrations are highly dependent on having a correct value for the extinction coeYcient for this compound. Following an extensive search of the literature, the orig...

in the safavid period, as opposed to previous periods such as the timurid era, there is not any discussion of organology in musical treatises and authors had just referred to the name of some instruments. thus, in order to investigate in this field, it is necessary to study other worthwhile historical sources. in the discussed historical period, there are lots of travel accounts which contain i...

Abstract Background Outcome measurement in forensic mental health services can support service improvement, research, and patient progress evaluation. This systematic review aims to identify instruments available for use as outcome measures this field assess the evidence most common instruments, specific context, which cover multiple domains. Methods Studies were identified by searching seven o...

The differential white cell counts produced by the Technicon H*1 Autoanalyser in profoundly leucopenic specimens were compared with those carried out by manual differential counting by light microscopy of peripheral blood smears stained with May-Grünwald-Giemsa stain. The correlation achieved allowed the H*1 derived differential count to be reported with confidence.
