The electrochemical performance of manganese ammonium phosphate (MnAP) intercalated carbon hollow sphere (CS) at four mass variates has been investigated. The XRD, Raman, SEM, and electrochemical studies reveal that only 50 mg of CS strongly intercalating with MnAP (MnAP@CS2) is observed. The half‐cell test has shown the profound pseudocapacitance for 50 mg intercalated MnAP@CS2 hybrid composite (2545 C g−1 @ 1 A g−1 in KI added 2 M H2SO4) and confirms the imminence of optimal mass concentration of CS with MnAP and the effect of KI redox additive towards enhancing the specific capacity. The supercapattery hybrid device (SBHD) using MnAP@CS2 as the positive electrode and as newly synthesized activated carbon (AC) derived from cucumis melo var agrestis as a negative electrode is examined in pure 3 M H2SO4 and in 0.025 M KI/VOSO4 dual redox additive added 3 M H2SO4. The exquisite complacency requisite on specific capacitance (536 C g−1/149 mAh g−1 @ 1 A g−1 @ 20 A g−1), energy density (80 Wh g−1), and capacity retention (89% for 5000 charge‐discharge cycles) have profusely advocating MnAP@CS2 and AC for SBH device applications.

This research was aimed to study and analyze the impact of the shocks of the agricultural net terms of trade (NBTT) on agricultural product (AP) in Iraq during the period (1990 – 2021), which are among the shocks affecting the agricultural sector and foreign trade, the research used quantitative approaches in estimating the levels of impact, including VAR model, variance decomposition analysis (VDA) and impulse response function (IRF). The results showed that VDA of AP was weak in respect of agricultural NBTT and vice versa. While IRF of NBTT was negative in respect of Ap, and the same result was for IRF of AP. The study recommended the need to consider strategies to support smallholder farmers, such as providing access to credit, soft loans, technical assistance and markets for their products, in addition of support the technological advancements for their role in shaping the relationship between agricultural trade and agricultural production.

In this work, a Particle Swarm-Based optimization algorithm is proposed to optimize the PID controller used in the Positive Output Re-Lift Luo converter for the Electric Vehicle application. The novelty of the work lies in developing an improved PID controller to explore the reliability of the re-lift Luo converter. In addition, the optimization improves the effectiveness of the closed-loop system that possesses high voltage gain with esteemed power density and efficiency. With the Particle Swarm Optimization control algorithm, $ {K_p} $ K p , $ {K_i} $ K i , and $ {K_d} $ K d values are tuned in such a way to obtain the appropriate steady-state condition with no peak overshoot or undershoot, much lesser settling time, no steady-state error, and improved dynamic performances. To analyze the system stability and to obtain better results, reduced-order state-space modeling of the Re-lift Luo converter is adopted, which offers high computational speed and accuracy. Initially, a PID controller is designed using the Zeigler Nicholas method, and the results are compared with the genetic algorithm and Particle Swarm Optimization algorithm. The time-domain analysis has been carried out to analyze and compare the converter's performance. The simulation results were verified experimentally, and the results prove the robustness of the proposed converter with a PID controller optimized using the Particle Swarm Optimization algorithm.

The main novelty of this research lies in combining natural fibers and mineral fillers to create a sustainable material with enhanced antimicrobial and structural properties, offering promising applications in various industries requiring eco-friendly and high-performance materials. This study investigates the fabrication and analysis of a green composite made from Cannabis sativa fiber reinforced (CSFR) with granite filler in an epoxy matrix, focusing on antimicrobial properties and structural integrity. Various amounts of granite powder (0, 3, 6, 9, 12, and 15 g) were incorporated into the epoxy matrix. The composite exhibited significant antibacterial activity was observed against E. coli. Mechanical testing revealed that the composite with 12 g of granite powder showed the best performance, with tensile strength improving by 11.4%, flexural strength by 12.3%, impact strength by 29% and hardness is improved by 17.5%. SEM analysis highlighted well-dispersed particulates and strong fiber-matrix bonding at optimal filler levels. TGA showed enhanced thermal stability, with the decomposition onset shifting from 240 °C to 280 °C and weight retention improving 90% at 350 °C. This study underscores the potential of Cannabis sativa fiber reinforced granite filler epoxy matrix composites as sustainable materials with excellent antimicrobial and structural properties for advanced applications.
