In this paper, we introduced two novel subclasses of bi-univalent functions, Με (α, Β(α, ξ)) and ΗΣ (α, μ, Β(x, ξ)), utilizing Lucas-Balancing polynomials. Within these function classes, we established bounds for the Taylor-Maclaurin coefficients |a2| and a3, addressing the Fekete-Szegö functional problems specific to functions within these new subclasses. Moreover, we illustrated how our primary findings could lead to various new outcomes through parameter specialization.

Abstract

The research was conducted to discuss the impact of Derna floods on children’s education and their mental and psychological state, and emergency measures to confront the disaster. It has explained and talked about the tragedy that happened in Derna and other eastern cities. Furthermore, it has been mentioned the coping mechanism for schools. In addition, this research has been mentioned the impacts of storm Daniel on Derna. And, it has been discussed the effective steps to rebuild education facilities in the affected areas. Besides, it has been explained how to help children who have been affected by floods, which must have been awared by parents and caregivers. Finally, it has been explained the impact of trauma on children and some important tips for the sectors on how to be better support children and young people affected by flooding.

The World Health Organization declared the COVID-19 outbreak to be a global pandemic in March 2020, also the COVID-19 pandemic has caused drastic changes across the globe, affecting all areas of life. However, the pandemic cannot be ended overnight and more social distancing and other self-care measures are needed to protect our Libyan community. Therefore, people´s awareness, knowledge, attitudes, and appropriate behaviors are instrumental to containing the pandemic. This study aims to create a questionnaire to determine the Libyan society's environmental awareness of COVID-19

Seven male specimens (one immature and six adults) of a rare species of Loureedia jerbae (El-Hennawy, 2005), are recorded for the first time in Libya, representing the first record of this species outside of Tunisia. Illustrations and a description are provided. Only the most recent adult of the specimens captured in October/November of 2019 to 2022 was examined, identified and described. Although Libya has one of the least recorded spider species in the Mediterranean region, it is promising to reveal more undiscovered and undocumented species through extensive research in this large country.

Urinary tract infections (UTIs) are common infections that happen by many types of bacteria. Some of bacteria have resistance against several types of antibiotics. Many medicinal plants used as an alternative treatment around the world. Marrubium vulgare L has been reported to exhibit several biological properties. Thus, the aim of current study is estimating antimicrobial activities of M. vulgare against Escherichia coli, Klebsiella pneumoniae and Staphylococcus aureus, which caused urinary tract infections, isolated from infected patients. In the results, the growth of all tested bacteria was inhibited strongly by methanol extract at 1.0% (w/v) with inhibition zones 11.00, 11.00 and 15.50 mm against E. coli, k. pneumoniae and S. aureus respectively. Besides, Minimum Inhibitory Concentration (MIC) values were ranged between 0.625 to 1.25 mg/mL. While, Minimum Bactericidal Concentration (MBC) values were ranging between 1.25 to 2.5 mg/mL. On the other hand, hexane extract also was inhibited the growth of E. coli, k. pneumoniae and S. aureus with inhibition zones 10.00, 11.00 and 12.50 mm respectively. In addition, MIC values ranging 2.5 mg/mL, while MBC values of 5 mg/mL against all bacteria.  In conclusion, the methanol extract of M. vulgare had a strongly effects on all bacteria compared to hexane extract, thus it can be developed as anti-bacterial agent.
