Silver nanoparticles (Ag-NPs), the most popular nanoparticles, possess unique properties. Achillea biebersteinii is a plant of the Asteraceae family rich in active antitumor components. The aim of this research was the characterization and investigation of the cytotoxic properties of Ag-NPs synthesized using A. biebersteinii flower extract, on a human breast cancer cell line. The Ag-NPs were sy...

AIM/BACKGROUND The development of resistance to synthetic drugs by target organisms is a major challenge facing medicine, yet locked within plants are phytochemicals used in herbal medicine (especially in the Arabian Peninsula) that may find application in this regard. In pursuit of unlocking these "hidden treasures," the methanol extracts of leaves, aerial parts, fruits, and resins of 17 plant...

Abstract Speech is one of the natural ways communication between humans, later extended as a means for human–computer interaction. It helps visually impaired people to read electronic texts and used in information retrieval language education. This paper proposed development text-to-speech synthesizer Afan Oromo (Oromo Language), using unit selection speech approaches. Although several works ha...

Unsupervised domain adaptation for object detection is a challenging problem with many real-world applications. Unfortunately, it has received much less attention than supervised detection. Models that try to address this task tend suffer from shortage of annotated training samples. Moreover, existing methods feature alignments are not sufficient learn domain-invariant representations. To these...

there is substantial diversity in achillea biebersteinii plants in iran. it has considerable different biological activities including antibacterial, antifungal, antioxidant, insecticidal, herbicidal and wound healing. research improvement for medicinal plants depends on the available genetic diversity. the assessment of genetic variability could increase the information for breeding programs. ...

Aqueous extracts of nine plants, known to have medicinal activity, were tested for their toxicity against the sweet potato whitefly, Bemisia tabaci Genn. (Homoptera: Aleurodidae) compared to the toxicity of the insecticide, Imidacloprid. Extracts of Lepidiuim sativum L. (Brassicales: Brassicaceae) killed 71 % of early stage nymphs, which was not significantly different from mortality caused by ...
