A sensitive method for electrochemical determination of molybdenum (VI) in plant foodstuff samples using Ni0.5Zn0.5Fe2O4 nanocomposite modified carbon paste electrode

In the present study, a new chemically modified carbon paste electrode (CPE) is constructed for rapid, accurate, simple, highly sensitive, and selective determination of Mo (VI) using differential pulse voltammetry. The electrode was prepared using magnetic nickel zinc ferrite nanocomposite (Ni0.5Zn0.5Fe2O4), as the modifier in CPE (Ni0.5Zn0.5Fe2O4/CPE). Mo (VI) was determined after preconcentr...

A revision on the taxonomy of the genus Pseudocercospora

Bakhshi. M. 2019. A revision on the taxonomy of the genus Pseudocercospora. Plant Pathology Science 8(1):1-14. DOI: 10.2982/PPS.8.1.1.    Pseudocercospora species are plant pathogenic fungi occurring on a wide range of herbaceous and woody plants. Since its early description of the genus, its taxonomy has always been challenging. In recent years, Multi-gene DNA sequence data have provided sig...

Quality of Residents’ Promotion Exams before & after Educational Intervention in 2010-2011

Introduction: Resident promotion exams are considered one of the most important summative exams in residency period that allow residents to proceed to a higher grade. Multiple choice questions are the most common and objective test in medical science education. Therefore, finding methods to improve quality of exams, particularly in specialty programs, is important. The aim of this study is to d...

Chemical characters in plant taxonomy: some possibilities and limitations.

Chemical plant taxonomy or chemotaxonomy of plants may be defined as a sciertific investigation of the potentialities of chemical characters for the study of problems of plant taxonomy and plant phylogeny. Plant taxonomy is the science of delimiting, describing and naming appropriately taxat and arranging them in a natural system of plants. Principles of chemotaxonomy were elaborated in the pas...
