Hasan f.abdalnaby@wau.edu.lyGuzlan M. Miskeen guz.miskeen@wau.edu.ly<p>In recent years, the widespread use of Internet of Things (IoT) applications has contributed to the development of smart cities, but with the growth of smart city networks, the risk of cybersecurity threats and attacks increases. Despite the spread of many security mechanisms such as encryption technologies and firewalls, it is impossible to avoid various attacks on IoT networks. To address this problem, machine learning has been used as an effective tool to detect attacks. This is done by applying a number of supervised classification algorithms to a dataset. This study reviews some of the common datasets for detecting intrusions into networks in general and IoT networks in particular, the most important of which are: KDD Cup '99, Kyoto2006+, NSL-KDD, UNSW-NB15, CIC-IDS 2017, CSE-CIC-IDS 2018. In addition to comparing them based on the number of features in each, the presence of recent attacks, the total number of records and the number of attack categories. At the end of this paper, the most important previous studies that dealt with the application of some machine learning algorithms on the data set under study were reviewed and the performance indicators were summarized, including accuracy and training time of the algorithms.</p>2024-10-19T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3235Practical Study Utilizing Reverse Engineering and Technical Feasibility Study for Manufacturing Products Locally Instead of Importing2024-08-05T12:08:11+00:00Imad Mokhtar Mosratiimadmokhtar@yahoo.comMabrouk M Abduljalelmabroukabduljalil@gmail.comAbdullatif Mehemed Gohmanben_guhman@azu.edu.ly<p>This work aims to conduct a practical study between the outcomes of reverse engineering techniques used in redesigning and manufacturing an initial model of the product intended to be manufactured, with linking its results in implementing technical feasibility studies to manufacture products locally instead of importing them.

This was performed by studying the effect of filler content (10, 20, 30 and 40 wt%) on mechanical properties of the composites including stress at break, elongation at break, impact strength and micro hardness. Also, a comparison study between using mixed and individual grasses has been attained. The stress at break was decreased with the addition of 10% mixed grasses, then increased as the mixed grasses content increased up to 30% and then decreased again. The incorporation of mixed grasses caused a significant decrease in the elongation at break. This decrease in the elongation at break was increased with increasing the grasses content. Impact strength was slightly increased with the addition of mixed grasses. Increasing the grasses content had no profound effect on the impact strength values of SBR composites. Hardness properties were slightly increased with the addition of mixed grasses. The optical image of SBR composite made 10% of mixed grasses content showed bad filler distribution, while composites with 20 and 30% grasses content had relatively better filler distribution. On the other hand, the image of composite with 40% mixed grasses content clearly showed the formation of filler aggregation. Mixed grasses appears to be relatively better than individual grasses (Halaf and Esbat) in order to attain composites with good strength properties. On the side, individual grasses seems to be better than mixed grasses in producing composites with relatively better impact strength and hardness properties. In both cases (individual or mixed grasses), the best content of grasses in order to provide good mechanical properties should be in the range of 20-30%. In conclusion, composites obtained from these grasses (individual or mixed) </p>2024-10-16T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3252The Role of Information and Communication Technology in Improving the Financial Performance of Banks (An applied study on commercial banks in the eastern region of Libya2024-06-22T02:08:58+00:00Nabil Mohammed Berras Alinabilberrasali@yahoo.comIsmail Almahde M SmewIsmail.smew@uob.edu.ly<p style="direction: ltr;">This study aimed to test and determine the extent to which bank departments understand and realize the importance of the concept of information and communications technology and to know the extent of its use to improve the financial performance of Libyan commercial banks whose main management is located in the eastern region.

Many processes have been invented to achieve optimal ammonia production. Currently, ammonia is produced primarily through the Haber-Bosch process in which nitrogen and hydrogen react in the presence of an iron catalyst to form ammonia. Hydrogen is formed from natural gas and steam reaction at high temperatures and nitrogen is supplied from the air. Other gases (such as water vapour and carbon dioxide) are removed from the reactor inlet gas stream and nitrogen and hydrogen are passed over the iron catalyst at high temperature and pressure to form ammonia. In this work, a simulation of the ammonia manufacturing process was performed on Aspen Hysys 3.1 software. Using (294) kg mol/h for methane flow, (10253) kg mol/h for hydrogen gas, and (3418) kg mol/h for nitrogen gas, about (3663) kg mol/h of ammonia was produced, which is equivalent to (67248) kilogram/h at a concentration of (0.9883). It was also found that ammonia production increases with higher flow pressure in the feed line of the industrial unit. I also use the Peng-Robinson model to better adjust the thermodynamic equilibrium process.</p>2024-10-16T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3143Investigation on The Effect of Zizyphus Spina Christi on the Corrosion Inhibition of Medium Carbon Steel in 0.5M Hydrochloric Acid Solution2024-05-09T22:01:22+00:00Taha Abdullahtah.abdullah@sebhau.edu.lyMasuoda Farhat mas.ali@sebhau.edu.lyFatma Alarbi fatm.alarbi@fezzanu.edu.ly<p>This study aimed to examine the influence of an inhibitor, <em>Ziziphus spina Christi</em> (ZSC) leaves, on the corrosion of medium carbon steel in 0.5 M Hydrochloric acid (HCl) solution over the temperature at 30 and 60 °C by weight loss measurements. Chemical analysis has been used to determine the impact of adding hydrochloric acid on the corrosion and corrosion inhibition of mild steel in 0.5 M hydrochloric acid (HCl) at 30 and 60 °C in the absence and presence of aqueous and alcoholic extracts of (ZSC) plant. The efficiency of corrosion inhibition was assessed using a weight loss measurement method. The standard approach to measuring the weight loss of metal cylinders exposed to corrosive environments is called laboratory immersion corrosion testing. At both temperatures of 30 °C or 60 °C, it has been discovered that the effects of inhibitor concentration on the corrosion rate of low steel increase with inhibitor concentration. To find the most accurate isothermal equilibrium data set models for the employed inhibitor, experimental data was used. All of the employed adsorption isotherms, such as the Temkin and Langmuir isotherms, fit the results, although applying an alcohol extract inhibitor at 60 °C showed a slight improvement.</p>2024-10-16T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3124Classification of forest fire images using deep learning algorithms2024-05-27T21:43:55+00:00Bader N. Awedatbader_najep@yahoo.com<p>Deep learning techniques have emerged as one of most significant and advanced technologies in field of artificial intelligence over past two decades. These techniques demonstrate exceptional capabilities in analyzing complex data, with one of promising applications being accurate and effective wildfire detection in images. Deep learning algorithms serve as powerful and efficient means for image classification, including classification of forest fire images. These algorithms constitute an important part of field of image analysis and computer vision, as they can handle high-dimensional data and recognize complex patterns in images. Deep learning algorithms are used in classifying forest fire images to accurately identify and classify fire-affected areas, enabling prompt and effective actions to mitigate fire damage and protect environment and properties. It is worth noting that deep learning algorithms require large amounts of training data to achieve optimal performance, in addition to advanced technology for efficiently processing and analyzing images. By using deep learning algorithms in classifying forest fire images, classification accuracy and identification of fire-affected areas can be improved, allowing for effective allocation of efforts and resources to deal with fires and reduce resulting damages.

In these tests, the well is produced at a constant rate for an extended period to achieve a stable pressure distribution, and then it is shut-in. Proper well shut-in is crucial as incorrect procedures can lead to inaccurate calculations. This study aims to interpret the pressure transient behavior in vertical wells that underwent pressure buildup tests for the bu-attifel field. The main objectives of the study involves analyzing the pressure buildup tests of three wells using KAPPA SOFTWARE, to estimate the permeability and skin factor for each well. Subsequently, the productivity index of each well is estimated using PROSPER SOFTWARE. Based on the derived parameters from the pressure buildup tests, the obtained results are compared with new production test data. Following that, a sensitivity analysis is performed for permeability and skin factor to diagnose the well condition and enhance productivity. We have obtained the results of the well-test analysis, and they are as follows: (A1=12.75 md), (A13=10 md), (A57=176 md). For permeability with positive skin factor values and the reservoir pressure, the results are: (5569 psi, 6232 psi, 6170 psi). Based upon the outcome, the productivity index for the wells was improved after comparing it with the new production test data.

Nowadays, the alternative methods for producing energy also are developed. One ways is to use hydrogen as a source of electricity which is generated from mixing hydrogen with oxygen via the electrochemical process. The current work is dealing with the factors that affect the amount of hydrogen production, such as voltage and amperage Two different electrolytes were employed in this work (NaOH & KOH) to evaluate the H<sub>2</sub> production levels. Two ways used for characterizing the stability of electro-catalysts to produce hydrogen via the electrolysis. One is the relationship (I–t curve) which measures the current variation with time under a fixed potential. In this way, the results showed that the changes in H<sub>2</sub> production values at different currents in both NaOH and KOH was observed. The changes may attribute to the conductivity of the electrolysis. The other ways for characterizing hydrogen production via the electrolysis is applied the relationship (E–t curve) to measure the potential change with time at a fixed current. Here, the rate of hydrogen production decreased as voltage increased in both electrolyte mediums. This result explained in terms of overvoltage created over the electrode surface. </p>2024-10-30T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3430The role and Importance of Geographic Information Systems in the Field of Transportation(Review paper)2024-07-23T11:32:22+00:00Alaa Al-Rahman Ali Al-Fatlawiaalaa94iq94@gmail.comAsmail Godan Naielasmaiel.naiel@academy.edu.ly<p>Roads are among the most critical infrastructures in our lives, upon which we rely heavily for the transportation of goods and commuting.

This study focuses on how rock properties respond to temperature variations, specifically through Microwave Irradiation (MI) and Shock Cooling (SC), and the implications of these changes for civil engineering, oil and gas drilling, and mining. In civil engineering, such knowledge is vital for designing stable and durable foundations. In drilling and excavation, altering rock properties to weaken rocks can enhance drilling efficiency, increase the Drilling Rate of Penetration (ROP), and reduce operational costs. The objective of this review is to consolidate research findings on the impact of MI and SC on rock properties, such as mechanical strength and mineral composition. By assessing these studies, the review aims to identify the potential benefits of using MI and SC to improve drilling performance, extend the lifespan of drill bits, and minimize drilling expenses. The review also explores the mechanisms through which these temperature-induced treatments create micro-fractures that facilitate easier drilling. In conclusion, the compiled research demonstrates that both MI and SC can significantly alter rock properties, offering practical applications in drilling and excavation. These techniques can effectively reduce rock strength, leading to improved ROP and cost savings in drilling operations. The insights provided by this review could guide future developments in engineering practices, particularly in enhancing the efficiency and sustainability of drilling activities.</p>2024-11-05T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3402The role of the information specialist in the digital environment of Algerian university libraries: The central library of Mouloud Mammeri University of Tizi Ouzou is a model2024-06-20T21:16:07+00:00Karima Amrouchekarima.amrouche@ummto.dzKamal MessaoudiKamil.messaoudi@univ-biskra.dz<p> The field of libraries and information has witnessed amazing technical developments that have affected all office jobs and activities. Perhaps the changes brought about by the Corona pandemic and the accompanying comprehensive closure of libraries and information centers were a stronger motivation to change the role of the information specialist in light of the digital environment and made it mandatory for him to have cognitive skills to control technologies. The services of information institutions have also turned into remote information services in order to continue work outside the workplace. This study attempts to identify the digital information services provided at the central library of Mouloud Mammeri University in the state of Tizi Ouzou in order to identify the reality of providing these services and the extent of the competence of the information specialist in presenting them for the purpose of evaluating them. These services and identifying the gaps and shortcomings in order to correct them and show the strengths to enhance them. To achieve the objectives of the study, the descriptive analytical method was used to study the reality of the situation in the central university library under study. Observation and interviews were also relied upon. Finally, the results of the study proved that the library under study is progressing. Moving forward towards digital transformation, a set of suggestions have been presented that would improve the level of information services provided, achieve the satisfaction of the audience who benefit from them, and meet their current and future desires. </p>2024-11-05T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3427Kinetic, Isotherm Studies of the Adsorption of the Congo Red Dye by Posidonia Spheroids Plants Sea Balls (PSPSB).2024-06-26T19:04:15+00:00Ragwan M.

The study evaluated some physical properties such as moisture content, and solubility. Moreover, the effect parameters, including pH, adsorbent dose, contact time, and initial dye concentration, were examined for their effects on the adsorption process. The optimal pH for adsorption was found to be 3. The percent removal(%) of the dye increased with the increasing adsorbent doses and initial dye concentrations until reaching the equilibrium state. The contact time to equilibrium was 20 minutes, and the adsorption capacity maximum reached 49.96 mg/g. Kinetic reaction results indicated the adsorption process followed a pseudo-second-order reaction model more fit than a first-order model. Isotherm analyses showed the adsorption process fit with Freundlich isotherm, suggesting that the adsorption process is multi-layered and occurs on a heterogeneous surface. The findings confirm that PSPSB are adsorbents effective for removing various pollutants, including dyes and heavy metals, from aquatic environments.</p>2024-11-04T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3409Improving Vehicle Identification Number Detection Accuracy with YOLOv5 and Histogram Equalization2024-09-19T17:17:02+00:00Hasan Alkhadafe has.alkhadafe@sebhau.edu.lyZahiyah Khalleefahza.khalifa@sebhau.edu.lyIbrahim Nasiribr.nasir@sebhau.edu.ly<p>This study examines the effectiveness of different image preprocessing techniques for object detection models, using a dataset of VIN images from Roboflow.

By reinjecting treated and filtered water into tanks, this approach can help maintain tank pressure, increase hydrocarbon production, and reduce environmental impact. The goal of this project is to create a water injection model using Eclipse tank simulation software to better understand water injection methods to maintain tank pressure. A basic reservoir model is utilized in this investigation. The simulation was performed about 52 years using ECLIPSE Reservoir simulator. In all cases, result shows that oil production with water injection is higher compared with the base case. With this, it would be preferred to apply waterflooding for oil recovery in depleted reservoirs to the use of primary methods. It is also observed that water breakthrough is earlier and water production increases gently with water injection rates. Sensitivity on the injection rate using the 3D model showed that the injection rate has impact on the process. The pressure increases with high injection water rate in all cases. Despite higher reservoir pressure and early in water breakthrough, water flooding accounts for less oil recovery due to rapid water production. Generally, based on the results and discussions, it can be concluded that the water injection option can be used to increase the reservoir pressure to a good extent. </p>2024-11-03T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3331Predicting Chronic Kidney Disease Using Filter and Wrapper Feature Selection Methods with Machine Learning Techniques2024-07-28T01:21:46+00:00Mohammed Shantalmoh.shantal@sebhau.edu.lyAlmahdi Alshareefalm.alshareef@sebhau.edu.lyOmar Ahmid oma.ahmid@sebhau.edu.ly<p>Chronic kidney disease (CKD) is a condition characterized by the gradual loss of kidney function over months or years. Predicting this disease is a crucial issue in the medical field. Therefore, an automated tool utilizing Machine Learning (ML) techniques to assess a patient's kidney condition would be beneficial for doctors in predicting CKD and improving treatment. In the ML process, the preprocessing stage is a vital step that enhances data quality. Feature selection, a key preprocessing method, removes irrelevant or redundant features, thereby simplifying the model and reducing the number of features. This research explores the potential of various feature selection methods. The feature selection methods are categorized into filter methods (f_classif, chi<sup>2</sup>) and wrapper methods (Recursive Feature Elimination with Cross-Validation RFECV) using Random Forest classifier and Support Vector Machine. The accuracy of classifiers was used to evaluate the performance of the full dataset compared to subsets created using feature selection (FS).

Therefore, studying the transport properties of these aggregates when used as coarse aggregates in concrete production is of paramount importance. This study examines the influence of local aggregate source and size on the water permeability resistance of 30 MPa plain strength concrete. Nine concrete mixes were prepared, incorporating three types of coarse aggregates: basalt, white limestone, and brown limestone, with sizes of 10 mm, 14 mm, and 20 mm. The concrete specimens were subjected to water penetration testing in accordance with the British standard (BS EN 12390-8:2019). The results reveal that, at a constant aggregate size, concrete samples containing basalt aggregate exhibited the lowest water penetration depth, followed by those with limestone aggregates. It was observed that the water penetration depth decreased significantly when smaller aggregate sizes were used. Correspondingly, the permeability coefficient also decreased as the aggregate size in the concrete mix was reduced. The concrete mixes with basalt aggregates demonstrated the lowest permeability coefficients across all the studied aggregate sizes, followed by the white limestone aggregates. This indicates that the basalt aggregates were more effective in limiting water penetration due to their lower porosity, less void content, and lack of chemical reactivity at the aggregate-paste interface.</p>2024-10-16T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3161Technological Innovations for Physical and Chemical Remediation of Oil-contaminated Water and Soil: A Review (Part-I)2024-06-19T22:04:28+00:00Mohammed Alsakitma7326@mun.caAbdelsalam Abughararaa_nasar@mun.caAmer Aborigamaborig@mun.caStephen Buttsdbutt@mun.ca<p>The petroleum industry produces significant amounts of oily wastewater, either through the process of oil production named associated water, through the process of oil refinery, or because of pipeline leakage through oil transportation. Environmentally permissible oily wastewater treatment is a major problem for the petroleum industry. Nowadays, the focus has been on the awareness of the treatment methods of oily wastewater. Therefore, oil-water separation has become a recent obstacle, and it must be explored and resolved by petroleum industries to meet set standards and protect the environment. However, during the last decades of growing urbanization and industrialization worldwide, the consumption of oils and their derivatives has significantly expanded. Due to some factors such as poor management, incomplete combustion, pipeline leakage, and other incidental circumstances, petroleum leaks into water and soil and are nearly unavoidable during the process of petroleum extraction, transportation, processing, and utilization. Since the relative toxicity of petroleum and its products, petroleum pollutants in water and soil can seriously harm the local ecosystem and human health.

One of the most important strategies for reducing the production of e-waste is e-waste management. This necessitates taking the appropriate steps to change public awareness and disposal behaviour. This study was done among Tobruk Institute students. Surveys were given to 235 students who were registered for classes in April of the 2021 academic year. It recommends assessing students' attitudes and behaviours regarding e-waste management. In addition, the research aims to find out why devices need to be replaced as well as how students currently dispose of their electronic devices. This study used the analytical-descriptive approach by using (SPSS). The findings of this study show that only 55.9% of students have some awareness about e-waste. At the same time, the analysis of the students' behaviour indicates that, in general, they do not dispose of their electronic waste in an appropriate and environmentally friendly manner. This suggests that despite having some awareness about e-waste, the students' actual behaviour and practices when it comes to managing their own e-waste are lacking. The results have shown that the development of technology is the main reason behind replacing electronic products (54%). More than 80% of students replace their mobile phones within a period of less than two years. Keeping unused electronic products (PCs and laptops) at home was the most common method of discarding e-waste by students, and throwing mobile phones in the trash along with other waste was the second method.</p>2024-11-03T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3230The Impact of Innovative Leadership in Achieving Sustainable Environmental Development A Field Study on Berber Cement Factory – Sudan2024-05-26T23:35:38+00:00Azza Mustafa Faragalla Alawaddrazzamustafa59@gmail.com<p>The study aimed to investigate the impact of innovative leadership in achieving sustainable environmental development.

The simulator results show the reservoir pressure history curve is matching to the stimulation curve, this gives a good indication of the input data that has been entered to the model. The driving mechanism for all those reservoirs it comes from three natural forces, which are fluid expansion, PV compressibility, and water influx. The best method to choose as secondary recovery for this oil field is water and gas Injection. Water and gas Injection have the largest Total Field Recovery. Water and gas Injection have the highest Reservoir Pressure at the end of the project. The highest percentage of oil recovery was when the water and gas were injected and it reached 58%, then when the water was injected and it reached 55%, and then when the gas was actually injected and it reached 54%. The field pressure rise was greater when water and gas were injected, and the pressure reached 792 psi, while it was less when only water was injected, reaching 435.5 psi, and when only gas was injected, it reached 412.9 psi.

Ighleeleebqleleeb90@gmail.com<p>One crucial element of the infrastructure designed by civil engineers is the highway. Stone Mastic Asphalt (SMA) is a recently developed asphalt mix that is characterized by a high amount of coarse aggregate, filler, and asphalt, setting it apart from regular dense asphalt. As fillers, 6% calcium carbonate and 2% ordinary Portland cement (OPC) were added to the coarse-graded mix to prevent stripping and reduce binder drain down. The high coarse aggregate structure contributes to the creation of a stable matrix, improving its resistance to long-term deformation. This study's primary goal is to look at how varied ageing times and temperatures affect the performance of SMA mixtures. This study includes abrasion loss, permeability, and skid resistance performance tests. Utilizing a one-way ANOVA, results were examined. The findings indicate that there is no statistically significant relationship between age and skid resistance or abrasion loss. Meanwhile, the resilient modulus and skin temperature differential are statistically significantly impacted by the length of ageing.

Also, determining the size of an aquifer (based on its response to pressure support) provides a means of calibrating known physics against production data, which once calibrated can be used for prediction. In this paper, the types of natural drivers of the reservoir were estimated and compared using a program called MBAL after matching production history data with model results. The purpose of this paper is to evaluate the basic driving mechanisms and PVT analysis using MBAL software for Intisar D field. The final project results can be seen matching the real data of the reservoir with the program results using MBAL software. The simulation results show that the reservoir pressure history curve matches the stimulation curve, and this gives a good indication of the input data fed into the model. The driving mechanism for all these tanks comes from three natural forces, namely fluid expansion, compression, and water flow.

This prompted the research idea of simulating the collapse and the influencing conditions to assist in understanding the collapse occurrence. This paper discusses the utilization of practical methods and the 'Rock Plan' software to simulate the stages of slope failure. The analysis of simulation outputs reveals the impact of moisture content on the factor of safety and the relationship between driving forces and resistance. This paper highlights the importance of resistance strength in maintaining slope stability and how it diminished under the influence of rainfall pressure and a 65% increase in moisture content, which resulted in the slope collapse. The results demonstrate the influence of internal cohesion and friction angles on slope stability, identifying them as the primary factors contributing to the collapse. The study emphasizes the importance of using laboratory experiments to determine cohesion values and friction angles. It recommends the necessity of debris removal from water drainage channels and the use of simulation programs to assess the stability of parallel slopes along mountain roads before their construction.</p>2024-10-16T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3373Modeling and simulation of Internet of Things networks in smart buildings using queuing theory2024-07-11T11:57:13+00:00Mwahib Omer Imhimedma.emhemad@wau.edu.lyGuzlan Miskeenguz.miskeen@wau.edu.ly<p style="direction: ltr;">Smart building systems in major cities are equipped with Internet of Things devices to monitor some different indicators in these buildings, and for the purpose of avoiding a decrease in the quality of service for these systems.

The mean phosphorus levels did not show a significant difference between males (3.23 ± 0.23 mg/dL) and females (3.97 ± 0.50 mg/dL, p-value = 0.179), nor did the PTH levels (p-value = 0.976). In conclusion, the study revealed significant gender differences in height, vitamin D, calcium levels, and PHT among the student population at the University of Tobruk. Males were generally taller and had higher levels of certain biochemical. These findings underscore important gender-specific physiological and biochemical differences within this population. </p>2024-10-21T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3395Utilization of cellulose extracted from olive kernels (OK) and olive pomace (OP) to enhance drilling fluid properties in terms of filtration, viscosity and gel strength 2024-09-06T09:43:59+00:00Mohammed ALOWAmoh.alowa1@sebhau.edu.lyMahjoba S. Munayr Mhj.altieb@sebhau.edu.ly<p>This study explores the effects of cellulose derived from olive kernels (OK) and olive pomace (OP) on the properties of drilling fluids. The analysis revealed that both OK and OP cellulose exhibit similar density values across identical concentrations, indicating consistent density properties under the tested conditions. In terms of plastic viscosity (P.V.), OP cellulose demonstrated a slightly higher value of 10.4 cp compared to 10 cp for OK cellulose at a concentration of 0.1%, suggesting that both may be nearing a plasticity threshold where cellulose particle aggregation reduces thickening efficiency. Apparent viscosity (A.V.) peaked at 16.5 for OK and 15 for OP at a 0.1% concentration, illustrating distinct shear-thinning behaviours where viscosity decreased with increased shear rates at higher concentrations. Further, yield strength was found to be concentration-dependent, with OK cellulose peaking at 0.05% and OP cellulose at 0.1%. Filtration efficiency was notably improved by the addition of natural cellulose, with the highest filtration results observed at concentrations of 0.4% and 0.25%, achieving a value of 11.5 for both OK and OP cellulose. This suggests that increasing cellulose concentration can positively impact filtration control. The consistent performance of OP cellulose across various concentrations highlights its stability in enhancing filtration properties. Overall, the differences in cellulose behaviour between OK and OP are likely due to their unique physical properties, influencing their performance in drilling fluids.</p>2024-10-21T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3379Mechanical and Thermal Properties of Glass Powder Reinforced Concrete for Eco-Friendly Production Using the Voigt Model.2024-08-18T18:44:35+00:00Abdelmoutalib BENFRIDbenfridabdelmoutalib2050@gmail.comMohamed BACHIR BOUIADJRAmohamedbachirbouiadjra@gmail.comMohammed CHATBIchatbi_mohammed@yahoo.comZouaoui Rabie HARRATharrat.rabie@gmail.com<p>Cement is a fundamental material in concrete composition, making concrete structures the most common in construction compared to metal, wood, and other structures. However, cement production is also a major contributor to increased carbon dioxide emissions and global warming due to the high-temperature kilns used in its manufacturing. Laboratory studies and experiments have shown that fine glass powder can enhance the mechanical and thermal properties of concrete to some extent. In this study, we will examine ordinary concrete mixed with fine glass powder, and to achieve homogeneity, the Voigt model's homogenization method will be used to extract the mechanical and thermal properties of this eco-friendly concrete. Additionally, Bernoulli's mathematical model will be applied to calculate the deflection of an eco-friendly concrete beam.</p> <p>The results indicated a significant improvement in mechanical properties such as the modulus of elasticity and thermal expansion coefficient. Up to 35% of fine glass powder can be used as a substitute for cement, with reasonable improvements in these properties. Deflection is a critical mechanical and thermal phenomenon in the study of concrete structures, particularly in beams used in buildings, bridges, and individual houses. The results also showed that using Bernoulli's model to calculate beam deflection reveals that increasing the proportion of fine glass powder reduces deflection. This leads to economic benefits and significant environmental advantages, including the durability of concrete and the preservation of the ecosystem through the recycling of glass waste, which contains silica, an essential component in cement composition.</p>2024-10-20T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3392Predicting the Compressive Strength of Concrete Utilizing Machine Learning Techniques and Conventional Techniques2024-07-01T12:39:57+00:00Abdualmtalab Aliaayali@azu.edu.lyAbdalrhman Milada.milad@unizwa.edu.omHamza AlmadaniHamza.almadani308@gmail.com<p>In civil engineering, accurately determining the compressive strength of concrete is a crucial aspect of designing buildings. Precisely predicting this strength can lead to significant time and cost savings by quickly generating essential design data and reducing the need for trial mixes, thus minimizing material waste. This research employed two different types of soft computing approaches, specifically artificial neural network (ANN) and Random Forest (RF), to efficiently project the compressive strength (CS) of concrete to forecast the compressive strength of concrete reliably. The variables considered include age, cement content, fly ash, Blast Furnace Slag, water content, superplasticizer content, coarse aggregate, and fine aggregate. This study highlights the vast potential of cutting-edge machine learning models as a superior option for precisely predicting the compressive strength of concrete based on the concrete's components. The statistical analysis results show that all of the machine learning models displayed outstanding predictive abilities, as demonstrated by their high coefficient of determination () values of 99.5% and 95.3%, along with low Mean Absolute Error (MAE), Root Mean Squared Error (RMSE), and Mean Absolute Error values of 1.177, 3.069, 0.387, 2.657, Additionally, the compelling findings suggest that the proposed models based on the RF and ANN techniques significantly outperformed those proposed using conventional approaches.</p>2024-10-20T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3376A Comprehensive Evaluation of Polymer Additives in Modified Bitumen for Enhanced Pavement Performance 2024-07-24T00:39:03+00:00Hassan Awadat Salemhas712002@yahoo.co.uk<p>In Libya, as in many other countries, highway pavements primarily consist of bituminous mixtures, where the bituminous binder, despite its low proportion (5-7% by weight), significantly influences pavement performance. Standard bitumen often fails to meet desired performance levels under repeated traffic loads and adverse weather conditions. Over the last 20-30 years, the necessity to enhance pavement durability and minimize economic and environmental losses has led to the modification of bituminous binders with various additives, notably polymers. Successful bitumen modification requires understanding the characteristics of both the bitumen and the polymer used, as well as optimal production conditions for polymer-modified bitumen. This study compares 2 popular types of polymers (SBS & RUBBER) used in Libya. The results showed that the asphalt mixture with SBS & RUBBER improved the rutting % and Stabilty compared to the asphalt mixture without additives .</p>2024-10-20T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3375Comprehensive Study of The Impact of Water and Nanofluid Cooling on the Performance of Hybrid Photovoltaic Panels at Varied Irradiation Values 2024-08-29T20:51:42+00:00Khalid Hamoudahkhalidsalih2010@yahoo.comSaleh EtaigSaleh.Etaig@uob.edu.lyEsam A.

This study investigates the impact of water and nanofluid cooling on the performance of a novel hybrid photovoltaic (PV) panel prototype. The prototype incorporates a water-based cooling system utilizing a water and Al<sub>2</sub>O<sub>3</sub>-water nanofluid within a rectangular collector at the rear of the PV panel. A comparative analysis is conducted using this collector technique. The closed-loop, passive cooling system directly contacts the PV panel through its rear side with varying nanofluid concentrations. Results demonstrate significant improvements in thermal efficiency, with increases of 48 % observed at nanofluid concentrations of 5 % volume. Electrical efficiency rises to 12.7 % and overall efficiency and total efficiency also exhibit a notable rise, reaching 60 % and 79.2% respectively at nanofluid concentrations of 5 % volume. additional enhancement of efficiency before and after using nanofluid as coolant increases to 5.5 %. In this study, a new style collector design was developed in addition to the suction plate. Additionally, the cooling cycle in the flow duct is carried out continuously using the water and water + Al<sub>2</sub>O<sub>3</sub> as coolant. Therefore, the performance of the parallel channel of the plate, excluding PV/T and intermediate metal, was evaluated numerically. 3D numerical simulation was performed using finite element modeling (FEM) based on ANSYS Fluent software. Thus, the performance of PV/T obtained by the numerical simulation method was verified by external research. </p>2024-10-20T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3106Studying the Effect of Incorporating of Souknah (Al-Jufra) Limestone (SLS) on the Compression Strength of Hardened Cement Mortar2024-05-19T10:19:57+00:00Mohammed Al-Kilani Almadanimoh.ibrahim@sebhau.edu.lySalah Abdulla Gnefids.gnefid@sebhau.comMohammed Ibrahimmoh.ibrahim@sebhau.edu.ly<p>Mortar is the bonding agent that integrates brick into a masonry assembly. Mortar must be strong, durable, and capable of keeping the masonry intact, and it must help to create a water-resistant barrier. The qualities, quantities, and content of the components in the mortar affect these needs. The purpose of this study is to compare the compressive strength and engineering qualities of Soukanah (Al-Jufra) limestone (SLS) when it is partially substituted for Portland cement powder in mortar. Limestone substituted in part for cement is regarded as 5, 10, 15, 20, 25, 30, 35, and 40%. Samples of hardened cement mortar are tested for compressive strength after 28 days of age. The greatest compressive strength is only reached at 5% replacement, according to the results. This finding makes it evident that (SLS) can be used as a good 5% replacement for cement in cement mortar mixtures.</p>2024-10-16T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3365Evaluation of the genotoxicity of diazinon on the mitotic Index and mitosis stages in the roots tips in Allium Cepa.

When the results were analyzed statistically, the results showed that diazinon has toxic effects, as it caused a decrease in the mitotic Index in the cells of the growing tips of onion plants. It was also found that diazinon has an effect on the stages of mitosis, where It led to an increase in the percentage of chromosomal abnormalities in the different stages of division, and thus a variety of imbalances in each stage of division.

The FLFP problem can be reduced to a linear fractional programming problem using the ranking function for all triangular L-R fuzzy numbers coefficients, and then using the variable transformation method to obtain an optimal solution with optimum fuzzy objective function. This enables us to obtain many proposed solutions instead of a unique solution, which enables the decision-maker to make the best decisions.

Some individuals may be sensitive or allergic to sulfites, and exposure can lead to adverse reactions. Monitoring sulfite levels helps protect these consumers and allows researchers to evaluate the long-term health impacts of sulfite consumption and contribute to ongoing research in food safety. The goal of the current study was to determine sulphur dioxide (SO2) concentration in some widely consumed dried fruits in Zawia city, Libya. Also is to ensuring that dried fruits are safe for consumption. A nine dried fruit samples were randomly collected from local market in Zawia city, Libya. The sulfur dioxide concentration in dried fruit samples were measured by colorimetric method using ONDA TOUCH UV-21 Spectrophotometer. The mean sulphite residue in apricot, white raisins, black raisins, banana, mango, kiwi, imported fig, local fig, plum was 252.2±2.50, 154.0±2.65, 166.0±1.00. 419.0±3.71. 223.2±2.37. 352.7±2.08, 259.7±2.52, 0, 326.9±7.34 respectively. The concentrations of SO<sub>2</sub> in the studied samples were within the permissible limits according to FDA regulations (up to 2,000 ppm). It appears that the content of this food preservative in dried fruits consumed in Libya has no serious risk for consumers in Libya. </p>2024-10-19T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3346Basic Characteristics of Flowable Fill Materials Containing Demolishing Waste Materials as Cement Replacement2024-08-23T23:14:10+00:00Mushtaq Radhimushtaq.sadiq@uokerbala.edu.iqNoor H.

This paper produces the outcomes of experimental study that has intention to examine incorporation demolishing waste materials in production flowable fill materials. the experimental work was separated into two parts, first part investigates the pozzolanic activity for different demolishing waste materials (glass, clay bricks, and Autoclaved Aerated Concrete blocks). Six different mixes of demolishing waste powder were tested by pozzolanic activity index test. The second part used an optimal pozzolanic demolishing waste for producing FFM. Ten mixes of FFM containing the optimal demolishing waste material ranged from 5% to 20% as cement replacement were prepared. Then the basic properties of FFM like flowability , unconfined compressive strength at different age , density were examined.

The study employed a descriptive-analytical approach using a questionnaire as a tool for data collection. A sample of 396 residents from Al-Abyar was selected. The study concluded that the waste disposal sites in the city are not adequately suitable, causing significant environmental problems due to the pollution they generate. Solid waste management in Al-Abyar requires substantial improvements, particularly in the areas of recycling, community awareness, and legislation and policies. The study recommended developing and improving waste disposal sites to be located away from residential areas and equipped with treatment systems to reduce pollution. It emphasized the necessity of adopting an integrated framework for waste management that includes improving infrastructure, enhancing recycling programs, increasing community awareness, and improving legislation and policies to achieve sustainable and effective solid waste management in Al-Abyar. </p>2024-10-19T00:00:00+00:00Copyright (c) 2024 Sebha University Conference Proceedingshttps://sebhau.edu.ly/journal/index.php/sucp/article/view/3343Study of Physical and Chemical Parameters to Evaluate the Quality of Drinking Water for Some Groundwater Wells in the City of Al-Bayda, Libya2024-06-19T22:08:03+00:00Tariq.A.M TYEBtariq.a.m.tyeb@omu.edu.lyGalal M.
