The presence of residual antibiotics in water results in the development of antibiotics resistant genes. The available wastewater treatment systems are not capable of removing such antibiotics from sewage. Thus, antibiotics need to be removed before the discharge of wastewater. Adsorption is among the promising techniques for the wastewater treatment to aid the removal of a wide range of organic and inorganic pollutants. The present work is a contribution to the search for an economical method for the removal of low concentrations of amoxicillin (AMX) from water by adsorption on water treatment residue, WTR, taken from a local drinking water facility. The chemical composition and the adsorptive characteristics of the material were first

This study focuses on studying an oscillation of a second-order delay differential equation. Start work, the equation is introduced here with adequate provisions. All the previous is braced by theorems and examplesthat interpret the applicability and the firmness of the acquired provisions

المستخلص لم يجد الفن الاكدي الاهتمام المطلوب من الباحثين وقل الذين تطرقوا اليه في بحوثهم واغلبها اعتبرت دراسات قديمة، هذا ما دفعنا لاختيار هذا الموضوع والبحث عنه، ضم البحث في بدايته مقدمة تعريفية عن الاكديين وحقيقة اصلهم والملوك الذين توالوا على الحكم فيه ومن ثم تطرقنا الى ذكر بسيط عن النحات وطبيعة الأدوات التي سادت في تلك الفترة، ثم استعرضنا النحت الاكدي بانواعه المجسم والبارز

his research aims to identify fear of missing out on opportunities among university students in terms of gender and specialization (scientific and humanities). To achieve this objective, the researchers adopted the fear of missing out on opportunities scale developed by Subhi Hamid and Issa Al-Daghistani(2023). The scale, in its final form, consisted of 10 items. The researchers confirmed the psychometric properties of the scale. Then, it was administered to 140 male and female students selected using stratified random sampling from four colleges at the University of Baghdad (College of Arts, College of Education, College of Engineering, and College of Science) during the 2024-2025 academic year

This study is pointed out to estimate the effectiveness of two solvents in the extraction and evaluating the active ingredients and their antioxidant activity as well as anti-cancer efficiency. Therefore, residues from four different Brassica vegetables viz. broccoli, Brussels sprout, cauliflower, and red cherry radish were extracted using two procedures methods: methanolic and water crude extracts. Methanol extracts showed the highest content of total phenolic (TP), total flavonoids (TF), and total tannins (TT) for broccoli and Brussels sprouts residues. Methanolic extract of broccoli and Brussels sprouts residues showed the highest DPPH· scavenging activity (IC₅₀ = 15.39 and 18.64 µg/ml). The methanol and water ex

 The tax base is one of the bases of the technical organizing of taxes,   and that a good selection of the tax base effects the outcome of the tax and its fairness, and with the expansion of the tax range results a dangerous phenomenon called tax evasion, which became threaten the economies of countries and this phenomenon prevents the achievement of the state to its economic, political and social objectives which seeks to resolve this phenomenon and identifying all human and material potential and realize the real reasons that lie behind it.   The researcher found that tax authorities are weak in terms of it the technical material and financial abilities, the analysis of data show that then is a significant reve

This research aims to solve a problem in the field of accounting and financial knowledge in the world today, that is, the problem of creative accounting.
