The discrete Putzer algorithm is examined in this work as an effective technique for resolving linear and nonlinear difference equations. The approach simplifies calculations and offers analytical answers by utilizing matrix theory and eigenvalue analysis, particularly for higher-order and non-homogeneous systems. Its efficacy is demonstrated by examples such as Fibonacci sequences and population dynamics. The Cayley-Hamilton theorem is applied to increase the algorithm's usefulness and make it a potent tool for dynamic systems in both theoretical and practical settings..

Defence Mechanisms of Olive Tree (Olea europaea) under Heavy Metals Stress

Rabha M Mansur and Gamila M Ahmed
Heavy metals can bioaccumulate and biotransfer from both natural and artificial sources. Given that heavy metal concentrations above normal seriously threaten both plant and animal life, their contamination of plants and water is one of the biggest problems facing the globe today that must be addressed. In this work, we attempt to evaluate the buildup of heavy metals in the soil, their penetration into plants, and their impact on the physiological and biochemical functions of olive trees. Therefore, it was interesting to research the concentrations of heavy metals in Sidi Khaled-Derna plants and soil. Soil samples' physical and chemical properties, including pH, electrical conductivity, organic matter mass, phosphorus and nitrogen content. Random soil samples were taken from the study areas, the first area as the control (Barborg) and the second as the polluted area (Sidi Khaled). The results showed that the concentrations of metals in the soil exposed to the pollution and the trees gr.
