This study used wild barbines  (Bacopa Monnieri)  to control the southern cowpea beetle (Callosobruchus maculatus) and their effects on cowpea beetle eggs. Alcoholic extracts and nanocapsules were used at different concentrations, with the alcohol extract being 1000, 2000, and 3000 PPM. Eight out of ten eggs were unhatched, and two hatched, indicating that the 3000 concentrations had the highest egg toxicity rate. Regarding saponins at the same concentrations, the 3000 concentrations had the best results, whereas the 1000 and 2000 concentrations produced poorer results. Additionally, it was discovered that saponins had a stronger effect than terpenes. The nanocapsule concentrations that affected the Callosobruchus maculatus beetle's eg

his paper uses the finite element method (FEM) to study a Surface Plasmon Resonance (SPR) refractive index sensor based on D-shaped Polarization Maintain Photonic Crystal Fiber (PM-PCF). A chemically stable plasmonic material, gold (Au), with hemispherical structures having a radius of 50 nm, is applied to the surface of a D-shaped sensor to create the surface plasmon resonance (SPR) effect, enabling this SPR sensor to detect variation in the surrounding analyte refractive index (RI). The resonance condition will change when the refractive index of the targeted analyte changes, leading to a certain shift in the loss peak. Two resonant peaks are observed, one located in the visible part of the spectrum, and the second in the near-infrared

            The widespread use of the Internet of things (IoT) in different aspects of an individual’s life like banking, wireless intelligent devices and smartphones has led to new security and performance challenges under restricted resources. The Elliptic Curve Digital Signature Algorithm (ECDSA) is the most suitable choice for the environments due to the smaller size of the encryption key and changeable security related parameters. However, major performance metrics such as area, power, latency and throughput are still customisable and based on the design requirements of the device.

The present paper puts forward an enhancement for the throughput performance metric by p

This study aimed to investigate the characteristics of   new edible film prepared from deamidated rice bran protein (RBP). Deamidation was carried out at temperatures of 80, 100, and 120°C under varying pH conditions of 8, 10, and 12 for durations of 15 and 30 minutes to enhance protein solubility. The resulting film was then assessed for its physical, mechanical, and optical properties.

Heavy oil is classified as unconventional oil resource because of its difficulty to recover in its natural state, difficulties in transport and difficulties in marketing it. Upgrading solution to the heavy oil has positive impact technically and economically specially when it will be a competitive with conventional oils from the marketing prospective. Developing Qaiyarah heavy oil field was neglected in the last five decades, the main reason was due to the low quality of the crude oil resulted in the high viscosity and density of the crude oil in the field which was and still a major challenge putting them on the major stream line of production in Iraq. The low quality of the crude properties led to lower oil prices in the global markets
