p-primitive semifield planes [PDF]
International Journal of Mathematics and Mathematical Sciences, 1992 Publisher Summary This chapter present a study of the class of semifield planes of order p4 and kernel GF(p2) with the property that they admit a p-primitive Baer collineation; these are called “p-primitive semifield planes.”This is the class of planes obtained when the construction method of Hiramine, Matsumoto, and Oyama is applied to the ...

New examples of fractional dimensional semifield planes
Electronic Notes in Discrete Mathematics, 2013 Abstract This is a short round up of the fractional dimension of finite semifields and finite semifield planes. We show that the classical Knuth binary semifields can never be fractional dimensional and a special class of the generalized Knuth binary semifields is fractional dimensional, even though these two classes of semifields are isotopic ...

International Journal of Agronomy, Volume 2026, Issue 1, 2026.Plant‐based biopesticides provide a sustainable alternative to synthetic insecticides for managing postharvest losses caused by maize weevil (Sitophilus zeamais) and larger grain borer (Prostephanus truncatus). This study evaluated the phytochemical composition and insecticidal activity of methanolic extracts of Lantana camara, Citrus sinensis, Moringa

Journal of Chemistry, Volume 2026, Issue 1, 2026.Although synthetic pesticides have long been used to protect crops, their widespread use has led to significant health and environmental problems, including ecological contamination, resistant pest populations, and hazardous residues in food. These restrictions have sparked interest in natural pesticides (NPs), particularly the secondary metabolites of

New Phytologist, Volume 248, Issue 2, Page 576-586, October 2025.Summary Plant roots are vital for absorbing soil resources and directly impact crop productivity. Because nutrients are unevenly distributed through soil layers, root system architecture (RSA) is a key trait influencing nutrient uptake. Shallow RSA can enhance access to surface nutrients, while steeper architectures help reach deeper nutrients.
