A simple and homogeneous green liquid–liquid microextraction based on temperature-controlled ionic liquid (IL) process was developed for the selective extraction spectrophotometric analysis of zinc (II) ethylenebis (dithiocarbamate) (zineb) from different foodstuff samples including rice, wheat, corn, oat, cabbage, potato, tomato grain. The effect various parameters like pH, IL dose, temperatur...

background: in-depth knowledge of antibiotic principles is widely considered a necessary condition for appropriate prescribing of antibiotics. the study aimed at determining the impact of healthcare providers’ level of knowledge in bacteriology and principles of antibiotic prescribing on their abilities to prescribe antibiotics appropriately. methods: a structured questionnaire survey targeting...

on bacteriology. No radical changes have been made since the last edition, which was reviewed in this Gazette in December 1928. The scope of the work is the same and no new sections have been added. The length of the book is slightly increased. It is a book well suited to the student, whilst giving the necessary details for identification and culture of the various organisms, it does not dwell ...
