Hybrid Triple Quadrature Rule Blending Some Gauss-Type Rules with the classical or the Derivative-Based Newton-Cotes-Type Rules.
Get PDFHybrid numerical quadrature rules are widespread techniques for approximate computations of definite integrals. Such hybrid rules combine as many quadrature rules as long as they possess the same degree of precision. The revenue is a new mixed rule with a higher degree of precision than its constituted rules at least by two. Moreover, such mixed rules are quite simple and handy, because they do not involve any extra evaluations of the integrand. That is by relying on the same number of quadrature points of the constituted rules, the acquired hybrid rule performs more efficiently than its ingredients rules. In this paper; a triple hybrid quadrature rule has been constructed for the numerical integration of real definite integrals that do not possess a closed-form anti-derivative. At First, a dual hybrid rule was produced by blending Milne’s rule of Newton-Cotes type with the anti-Gaussian quadrature rule to prevail a dual rule of a degree of precision equal to five. Then the acquired dual rule is recombined with the composite derivative-based and mid-Point Newton–Cotes formula producing a hybrid triple rule of degree of precision equal to seven. The accomplished approach is satisfactory and efficient in the approximate evaluation of definite real integrals as confirmed analytically by the error analysis and numerically by some verification examples. To promote the degree of precision of the proposed triple approach, the numerical computations have been implemented in an adaptive environment
Evaluation of Empty Fava Beans Pods as Bioadsorbent for the Removal of Pb2+ from Aqueous Solutions Using Phytoadsorption Technique
Get PDFEnvironmental contamination with toxic heavy metals is a globally concerned issue. Cleaning up heavy metals from contaminated aquatic systems forces a lot of challenges. Phytoremediation processes are the interesting safe techniques that were focused by scientists and governments during the last decades for the up-taking of toxic heavy metals from ecosystems. Consequently, phytoadsorption approach was applied in this research using dry empty pods of fava beans (Vicia faba L.) to evaluate their potential for the removal of toxic lead heavy metal from its aqueous solutions. We have developed a green and simple method to remove lead ions (Pb2+) from their aquatic system. The obtained results have showed that the 350‒1000-μm biomass particles of fava beans pods were able to take up lead ions at highly rated removal percentages and high adsorption capacity using 100-ml, 100-ppm solutions at room temperature and neutral pH. For example, the highest removal percentage of lead ions was 66.8% with an absorption capacity of 3.34 mg/g using 2.0 g at a shaking rate of 200 OSC/min after 30 min. On the other hand, the removal percentage of lead ions using 0.1 g of fava beans pods biomass was 36.8 % with the highest absorption capacity of 36.8 mg/g at a shaking rate of 800 OSC/min at the same period of time. Therefore, the empty fava beans (Vicia faba L.) pods can be used as potential phytoadsorbents for the removal of lead and other heavy metals from the contaminated aquatic ecosystems

Terpenoids were the most abundant, with monoterpenes representing 21.82% of the extract. The primary components identified were methyl eugenol (27.24%), squalene (11.84%) α-bergamotene (9.83%), linalool (8.42%), and fenchyl acetate (7.56%). These results indicate that O. sanctum could serve as a valuable source of food and medicinal agents
Investigation of Impact of Antibiotics on Bacterial Strains Identified in Spring Water Located in Massa City, Libya
Get PDFThe emergence of antibiotic-resistant bacteria in drinking water sources poses a significant public health threat. This study examines the presence of antibiotic-resistant bacteria in four springs in Massa, Libya, and explores the impact of seasonal changes on antibiotic sensitivity. Water samples were collected from each spring during the autumn and winter of 2023, and antibiotic susceptibility tests were performed using different classes of antibiotics. The results revealed the presence of antibiotic-resistant strains of Escherichia coli, with significant interactions between seasonal changes, bacterial species, and antibiotic types. The study highlights the complex interplay between these factors, underscoring the need for a multifaceted approach to address antibiotic resistance in drinking water sources. The findings contribute to a deeper understanding of the dynamics influencing antibiotic resistance and provide valuable insights for the development of targeted strategies to mitigate this public health challenge

The Effects of Proving the State’s Administrative Responsibility for Damages Caused by The Circulation of Hazardous Materials and Waste (Compensation)
No full textتتمثل مشكلة البحث في انتشار وسائل تلوث البيئة نتيجة لأتساع التطور الصناعي والتكنولوجي وما ينتج عنها من أضرار لكل عناصر البيئة من إنسان وحيوان ونبات وما ينتج عن هذا الأضرار من مسؤولية مدنية. وتستخدم المواد الخطرة في كافة المجالات حتى أصبحت ضرورة لتلبية احتياجات المجتمع وتنمية اقتصاده ولقد تدخلت الدول بشكل ملحوظ في الآونة الأخيرة في الخوض في شتى المجالات والتي قد يترتب عليها مواد ونفايات خطرة. وتسأل الدولة بالتعويض عن الأضرار الناتجة عن أعمالها ونشاطاتها على أساس الخطأ أو بدون خطأ، وفقاً للقواعد العامة في المسئولية غير أن المسئولية لا تتحقق في أي من هاتين الحالتين، وبالتالي لا يمكن الحصول على التعويض إلا بتوافر أركان المسئولية الأخرى والمتمثلة في ركن الضرر. وإذا توافرت أركان المسئولية وموجباتها، فإن القاضي يقوم بتقدير التعويض الذي يغطي الضرر الذي أصاب المضرور نتيجة ارتكاب المسئول للفعل الضار، فالتعويض هو جزاء المسئولية إذ يعني جبر الضرر الذي لحق بالمضرور، سواء كان ذلك الضرر مادياً أو معنوياً.The research problem is the spread of means of environmental pollution as a result of the expansion of industrial and technological development and the resulting damage to all elements of the environment, including humans. Hazardous materials are used in all fields to the point that they have become a necessity to meet the needs of society and develop its economy. Countries have intervened significantly recently in delving into various fields that may result in hazardous materials and waste. The state is responsible for compensation for damages resulting from its actions and activities on the basis of error or without error, in accordance with the general rules of liability. However, responsibility does not materialize in either of these cases. If the elements and requirements of responsibility are met, the judge assesses the compensation that covers the damage that befell the injured person as a result of the responsible person committing the harmful act. Compensation is the penalty for responsibility
