Delving into the properties of nanostructured Mg ferrite and PEG composites: A comparative study on structure, electrical conductivity, and dielectric relaxation.

Magnesium ferrite (MgFeO) and polyethylene glycol (PEG) are materials known for their versatility in various applications. This study presents a comprehensive comparative analysis of the electrical conductivity and dielectric relaxation of nanostructured MgFeO and its composites with PEG. Through experimentation, it was observed that incorporating PEG into MgFeO did not lead to a high relative observed decrease or increase in electrical conductivity at room temperature.

Nasopharyngeal bacterial flora before and after adenoidectomy.

Fifty patients (23 males and 27 females), with chronically hypertrophied and infected adenoids were subjected to adenoidectomy. Pre- and post-operative nasopharyngeal swabs were taken to study bacterial colonization of the nasopharynx both quantitatively and qualitatively. Twenty healthy controls were included in this study.
