Bounding coefficients for certain subclasses of bi-univalent functions related to Lucas-Balancing polynomials
Journal ArticleIn 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.

Morphological features and distribution of Loureedia jerbae (El-Hennawy, 2005)(Araneae: Eresidae) in Libya
Journal ArticleAbstract
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

Using macroinvertebrate-based biotic indices and diversity indices to assess water quality: A case study on the Karasu Stream (Kastamonu, Türkiye)
İbrahim Küçükbasmacı, Abdulhamed M Omar Etriieki
Biomonitoring is an approach that uses indicators or sentinel species to assess the health or pollution of an environment, combining diversity based on specific taxonomic groups with the taxa’s indicator of pollution into a single index or score. Benthic macroinvertebrates are among the most preferred and valuable indicators of the biotic index. Our study aims to evaluate water quality and ecological status using biotic and diversity indices based on benthic macroinvertebrates. The macroinvertebrate samples used in this study were collected seasonally from 16 stations determined in Karasu Stream. These samples consist of 14747 specimens belonging to 9 orders and 40 families of Insecta, Malacostraca, Hirudinea and Oligochaeta. In addition, some physicochemical parameters were measured at the stations. The data obtained were analyzed using the Turkey-Biological Monitoring Working Group (TR-BMWP), Average Score per Taxon (ASPT), Family Biotic Index (FBI), Ephemeroptera, Plecoptera, and Trichoptera (EPT) taxon richness index, and Shannon-Wiener (SWDI), Simpson (SDI) and Hill’s diversity indices. Our results showed that the last six stations of Karasu Stream were under pressure due to various anthropogenic effects. According to biotic indexes, the ecological quality status of the water in the stations was determined to be High or Good in the first ten stations and Average, Poor, or Bad in the last six stations. The results of our study showed that TR-BMWP, FBI, and EPT indices are more reliable in determining water quality than the ASPT index and reflect the environmental situation better. Since the TR-BMWP index is adapted to macroinvertebrate taxa distributed in Türkiye, it can be used as a suitable tool for evaluating other rivers’ water quality in Türkiye.

Seasonal Variation of Zooplankton Abundance and Their Relation to Physical Factors of Ain-Zayanah Lagoon, Benghazi
Journal ArticleDescription
Background and aims
The physical parameters and the occurrence and abundance of zooplankton in Ain-Zayanah lagoon, Benghazi, Libya, were studied from August, 2005–July, 2006, as a part of detailed investigation on the feasibility of converting the lagoon into an aquaculture farm for captive breeding and culturing of different economically important edible fish, fish fry, molluscan and crustacean animals, and for culturing the zooplankton which form the food of these organisms.
Methods
Five different sites located near to the shore were selected in the lagoon for water and zooplankton monthly sampling and analyses. The physical parameters of the water included air and water temperatures, transparency, electrical conductivity, total dissolved solids, pH, dissolved oxygen and total hardness; they were analysed using standard methods. Various differences were revealed in the relationships of these parameters in and between sites, months and seasons.
Results
Seven major groups of zooplankton inhabited Ain-Zayanah lagoon; rotifers formed the dominant one (40.50%), followed by rhabtida (21.61%), crustacean larva (14.55%), foraminifera (13.23%), ostracoda (5.97%), copepoda (4.13%) and cladocera (0.01%). Air and water temperatures, pH, DO, electrical conductivity, TDS and hardness had different relationships with the seven zooplankton groups in Ain-Zayanah lagoon.
Conclusion
The results obtained were discussed extensively in the light of available literature in the fields, and suitable conclusions, suggestions and precautions to be taken were given in connection with the establishment of Aquaculture farm in Ain-Zayanah lagoon

Exploring the Feasibility of Implementing Online Learning at the Faculty of Science: A Case Study
Conference paperBackground and aims
In recent years, the education sector in Libya have been affected by wars and political fluctuations, impacting the quality and availability of education. There have been challenges in providing the necessary educational resources, as well as in training and qualifying teachers. E-learning, it can be an effective tool in improving education under difficult circumstances. Online education can provide opportunities for students to access educational resources easily, and can contribute to enhancing communication between teachers and students. E-learning can also play a role in developing students’ technology skills, which is important in our modern era. In 2019, the Faculty of Science at the University of Gharyan partially implemented online learning as a response to COVID-19 pandemic, and this program continued for two academic terms. Therefore, the paper aims to highlights both the advantages and limitations of E-learning within the environment of university education in Libya

A Robust Blind Grayscale Image Watermarking Technique Based on Schur Decomposition and Entropy Analysis
Journal ArticleA new robust blind image watermarking method based on lifting wavelet transform (LWT), and Schur decomposition in combination with discrete cosine transform (DCT), and entropy analysis for copyright protection of multimedia information is introduced in this paper. At first, the 2-level LWT is applied to the original image to improve the invisibility of the watermarking method and then the high-frequency sub-band of 2-level LWT is decomposed by DCT. Then, the DCT coefficients are divided into 4×4 non-overlapping blocks. After that, Schur decomposition applies to each selected block, while the first row, the first column element of the upper triangular matrix is used to embed the watermark. For evaluation, the invisibility and robustness of the proposed watermarking method, the peak signal to noise ratio (PSNR), and normalized cross-correlation (NC) are used to measure the quality and the ability of the proposed watermarking method to be robust against signal processing operations and geometric attacks. Experimental results have demonstrated that the proposed method is achieved a very good tradeoff between invisibility and robustness. The comparisons with other scheme have shown that the proposed digital watermarking scheme has a superior performance in terms of invisibility than other.

Conference paperAbstract
The research was conducted to discuss the impact of storytelling and theater in building a remarkable personality and moral values in children. Furthermore, it has been mentioned the importance of preschool period and educated family to help of building the child’s personality and cultivating moral values. In addition, this research has been mentioned that in Libya there is not separation between moral education, strong personality and religion, which has been gotten all his values from second language and it has been explained and clarified the character development.
Moreover, it has been discussed two main headlines, ‘the storytelling and the child’s early age’ and ‘the role of storytelling and theater to create a creative and strong personality.
Besides, some tricks and plays techniques have been mentioned to enhance the creativity and remarkable personality among children, (pretend play / language play /musical play and play drawing and writing).
Finally, some advices and recommendations have been given to the parents and teachers in order to guide them to the appropriate ways to establish the child’s personality and moral values.
