Pharmacoepidemiologic Studies Using Claims Data : Possibilities and Limitations

Studies on Centrifugal Clarification of Sugarcane Juice - Possibilities and Limitations

A centrifugal clarifier based on the principles of a hydrocyclone with an impeller was developed for centrifugal clarification of sugarcane juice, for improvement in the quality of jaggery and khandsari. The developed clarifier and an existing standard sedimentation disc centrifuge were tested in regards of effect of operational parameters, namely, settling, boiling, clarificant addition and sa...

Best Practices for Conducting and Reporting Pharmacoepidemiologic Safety Studies Using Electronic Healthcare Data

Magnetorheological elastomers – possibilities and limitations

The mechanical properties of magnetorheological (MR) materials can be changed continuously, rapidly and reversibly by an applied magnetic field. Solid MR materials consist of magnetically polarisable particles, generally iron, in an elastomer matrix. The required iron concentration is high, about 30% by volume. Problems and solutions will be discussed related to MR-technology. Finally long-term...

Validity of perinatal pharmacoepidemiologic studies using data from the RAMQ administrative database.

BACKGROUND The RAMQ prescription claims database (RAMQ-Rx) is increasingly being used in perinatal pharmacoepidemiologic studies; but, there are reasons to believe that results generated with the RAMQ-Rx might not be generalizable to all patient populations. OBJECTIVES Compare characteristics between pregnant women insured by the RAMQ-Rx and those insured by a private drug insurance plan. M...

Using coarse-grained occurrence data to predict species distributions at finer spatial resolutions—possibilities and limitations

For effective conservation planning, resource managers around the world require information on species distributions. Available data, however, are often too coarse in spatial resolution to be of practical use. We describe four modelling techniques that harness the information contained in coarse-scale occurrence records to predict species’ distributions at the finer resolutions relevant to cons...
