The study has been aimed to evaluate and compare the antioxidant 

activity in peel and pulp extracts of banana. The effect of variation of banana parts on 

the antioxidant activity showed different values. The DPPH free radical scavenging 

activity of banana parts (peel and pulp) were determined using different extracts 

(methanol, ethyl acetate and ethanol). Results represent that all extracts showed very 

good activity at highest concentration 800µg/ml. Among the all extracts, methanol 

extract of pulp exhibited highest free radical scavenging 91.27% at 800µg/ml.

Maximum reducing activity of banana peel was observed at 800µg/ml and showing 

0.260 in methanol. The data showed that, the entire sample increased their reducing 

ability when the concentration of extract increased. There was slight difference in 

reducing ability of all the three extracts. . The study suggests that peel and pulp 

extracts of banana could be useful to combat free radical mediated diseases.

An artificial neural network (ANN) is a kind of human brain learning method software simulation. ANN is suitable for classification issues and has proven successful in many practical applications. Signal interference, power consumption, and signal noise are the main issues in signal processing research. This project proposes AALR, attempts to develop a neural network demodulator and machine learning technology. As a result of the new concepts, the neural network demodulator processing speed has improved by 88%, increasing output accuracy by 7%.

the role of inspector is seen as a strategy to monitor and develop the education quality. The purpose of this study is to explore the role of Libyan secondary school inspectors in implementing the inservice training program offered by the government. A total of 31 English language teachers completed a questionnaire. Results revealed that the role of inspectors is passive in some aspects of implementing training programs because the Center of In-Service Training in Libya focuses on training teachers rather than inspectors. Therefore, inspectors need to be effectively involved in the process of training programs to meet teachers' needs, develop and update teaching skills. The findings prompt a re-thinking about the role of inspectors in implementing the in-service training programs to provide great insights into the education in the Libyan context.  

The pollution of the Earth-system by microplastics (MPs) has attracted the scientific community's attention during the last decade due to the ability of MPs to alter the soil and agronomic lands properties and affect the soil flora and fauna, and thus via food chain may harm human health. The current review attempted to survey several previous studies to demonstrate the possible sources of MPs in soil characterised as primary and secondary sources depending on the way MPs are generated. Most of MPs released from these sources ended into the soil and can emigrate within soil profile, which negatively affects several physiochemical soil properties, soil biota, and plants that may alter biodiversity and agronomic land productivity. The bioremediation of MPs-polluted terrestrial environment using some microorganisms is an optimum economic and eco-friendly technology. This review is a first step to help researchers identify the main sources and effects of MPs pollution in Libyan farmlands to stand up on the current levels of these substances in soil and suggest future strategies to avoid possible harm impacts of MPs pollution over our country. ا
