Abstract Experiments were performed investigating citronella (Cymbopogon winterianus Jowitt) as a repellent to honeybee Apis mellifera (L.) (Hymenoptera: Apidae) in Egypt, it was conducted laboratory the Department of Entomology and Pesticides Science, Faculty Agriculture, Cairo University, check long-term survival when exposed different nano insecticides alone or combined with at same examinat...

In this paper, we present the design of four different circular bioassay platforms, which are suitable for homogeneous microwave heating, using theoretical calculations (i.e., COMSOL™ multiphysics software). Circular bioassay platforms are constructed from poly(methyl methacrylate) (PMMA) for optical transparency between 400-800 nm, has multiple sample capacity (12, 16, 19 and 21 wells) and mod...

This work proposes an outstanding screening magneto-bioassay for the early identification of bovine subclinical mastitis. Haptoglobin (Hp) was used as a promising biomarker diagnosis To this end, novel chitosan-modified magnetic particles, coated with haemoglobin-modified polyaniline (MNPs@Chi/PANI-Hb), have been integrated in sensitive electrochemical Hp bioassay. Haemoglobin bioreceptor due t...

Medicinal and aromatic plants with allelopathic effect are a potential source of natural herbicides. The experiment was conducted in order to assess herbicidal meadow sage (Salvia pratensis L.) on germination growth weed species velvetleaf (Abutilon theophrasti Med.) common corn-cockle (Agrostemma githago L.). Water extracts from S. dry biomass different concentrations were evaluated under cont...
