In this study, a silver nanoparticle (AgNPs) was created using a biological technique from an extract of the fungus Metarhizium anisopliae. The characteristics of the prepared AgNPs were identified by utilizing the optical, ultraviolet, and infrared absorbance spectroscopy. The shape, size, and charge distribution on the particles were determined by using scanning electron microscopy and zeta voltage analysis. The analysis of biological activity of the silver nanoparticles showed its effectiveness in treating pollutants, as confirmed by the reduction of higher than 93% weight of crude oil in contaminated water samples. The crude oil mass was effectively transformed into the gelatinous mass that lacks consistency and emulsification. The chemical analysis of NP-treated and untreated crude oil- contaminated water samples was performed using gas chromatography mass spectrometry (GC MASS). The results displayed the emergence of 55 graphic peaks, each of them indicating a chemical compound, in the control sample, while in the study sample, about 51 of these peaks disappeared and the area of the remaining 4 peaks was reduced. The silver nanoparticles' capability to maintain their effectiveness under cryogenic storage conditions for six months was tested and compared to that of the fungal isolation before the production of the silver nanoparticles. The results showed no significant changes in the shape, size, and efficiency of the silver nanoparticles in the treatment of oil pollutants in water. The results indicated the higher efficiency of the silver nanoparticles, as compared to chemicals, in treating petroleum pollutants as well as enhancing the solubility, emulsification, and degradation of hydrocarbons. In addition, the AgNPs are characterized by the availability of inexpensive, easy, fast to produce, and environmentally friendly production materials, as compared to the usage of chemical products that are highly toxic to aquatic organisms, expensive to produce, and highly accumulative in the ecosystem, i.e. environmentally unsafe.

Female aging is one of the main factors influencing reproductive fertility. The existing experimental study was planned to investigate the L-carnitine (LC) treatment effect on the body weight of adult young 8–10 weeks old and aged 26–28 weeks old female mice and the preimplantation embryonic development of their embryos. This study involved 40 mature young (n=20) and aged (n=20) old female mice. The animals were weighed and divided into 4 groups according to their age (n = 10). The control groups of young and aged mice groups were orally administered distilled water, while the young and aged mice that were treated orally with 10 mg/kg LC daily for 2-3 estrous cycles were considered as treated groups. Then, all female mice were mated with adult males. The weight of pregnant mice on 1-day post coitum was recorded and then euthanized to harvest early cleavage embryos. The embryo development was examined and evaluated their grading according to A, B, C and D. The results showed that the body weight of mice in both young LC and aged LC groups reduced significantly (P≤0.01). The grade A embryo in 1-day post coitum in young and aged LC groups improved significantly (P≤0.01). However, the development of embryos grade A in the young LC group was higher than that of the aged LC group. It was concluded from these findings that the oral supplementation of LC can reduce body weight and improve the preimplantation embryonic development proportions.

A new Azo Dye ligand HL was 4-((3-formyl-2-hydroxyphenyl)diazenyl)-N-(5-methylisoxazol-3-yl)benzenesulfonamide,this synthesized ligand was used for complexation with different metal ions like Cr(III), Fe(III), Mn(II) and Pd(II) by using a molar ratio of ligand: metalas 1:1. Resulted compounds were characterized by NMR (1H and 13C), UV–vis spectroscopy, TGA, DSC, FT‐IR, MS, elemental analysis, magnetic moment and molar conductivity studies. The results showed that the geometrical structural were octahedral geometries for the Cr(III), Mn(II) and Fe(III) complexes, square planer for Pd(II) complex. The antioxidant activities of the prepared compounds were assessed by using 1.1‐diphenyl‐2‐picrylhydrazyl as the free radical, and the results showed that the complex azo dye were found to possess potent antioxidant activity. The structure–activity relationship of the ligand and its complexes indicates that the presence of electron‐donating moieties, such as Cr(III), Mn(II) and Fe(III), in the chemical structure increases the antioxidant activity, whereas the Pd(II) complexes diminished the antioxidant activity, indicating the superior activity of the hydroxyl radical (OH·) over the superoxide radical.

The research interest in nanomaterials preparation from natural products as a green method and their application in various fields applications, tremendous attention has been taken to the green composition of nanoparticles. ZnO can be considered one of the most widely used metal oxides for most requirements of daily used products. In this research ZnO NPs prepared by using Petroselinum crispum (parsley) extract and to make the first study of toxicological evaluation of ZnO NPs their effect aspects on Honey bees (Apis mellifera). ZnO NPs have been charactarized by using SEM, EDX, XRD, UV-Vis and FTIR Spectroscopy. The toxicological evaluation of ZnO NPs has been applied to a honey bee. The lethal ZnO concentration was obtained, and the LC50 range calculation values were changed during 288 hours of feeding to ZnO nanoparticles at different concentrations (25, 50, 250, 500 mg per 100 ml) and the obtained LC50 values changed from 275, decreasing to 162.55 for the research range times after every 24 hours of exposure feeding calculations. In addition, for the group treated with 500 mg of ZnO per 100 ml, higher mortality was observed compared to other concentrations as it increased more than all other items indicating the above concentrations but not with the control group. The ergonomic design for creating a honey bee shelter was first introduced and no similar investigations were found in the literature.

This paper proposes a multi-objective facility model of coverage location problem to determine the number, locations, and redeployments of Emergency Medical Services (EMS) system. The EMS runs with two types of ambulances, Basic Life Support (BLS) and Advance Life Support (ALS). The suggested Multi-objective Coverage Location model (MO-CL) considers a bi-objective function, which is minimizing the EMS costs and the fatigue of EMS crew members. This can be managed by reducing the number of redeployments for both types of ambulances while still providing the required coverage levels. The MO-CL model is based on the approximation hypercube model that eliminates the assumptions of autonomous ambulance operation and system-wide busy probability. It can be solved by applying a modified MO-CL search algorithm. The model and solution method have been applied for a case study based on real data collected from the Al Noor Specialist Hospital in Makkah, Saudi Arabia during the period of fifteen days of Hajj pilgrimage. The results showed that, to achieve the 95% coverage threshold of critical and non-critical demand, the MO-CL model needs at least 64 ambulances (29 ALS, 12 for BLS backups, and 23 for BLS) and 19 redeployments for every day (9 for ALS, 2 for BLS backup, and 8 for BLS).

In this study, nonlinear optical (NLO) properties of nitro-thieno [3,2-b] thiophene-fullerene (C20) molecule was systematically investigated using density functional theory (DFT) methods at the B3LYP level with a 6-31 + G(d,p) basis set. Fullerene (electron-donor) is associated with thieno [3,2-b] thiophene (π-conjugated bridge), forming a charge-transfer framework, and nitro is a strong electron-acceptor. The dynamic properties of the molecule, including first and second hyperpolarizability, resulting from second harmonic generation β(-2ω; ω,ω), third harmonic generation γ(– 2ω; ω, ω, ω), Pockels effect β(-ω; ω,0), and Kerr effect γ(–ω; ω, 0, 0), were investigated, which are essential evaluation indexes for creating nonlinear materials. The molecule exhibits excellent nonlinear responses, where it was found that the highest linear response of the coefficients above at the wavelength 455.6 nm. Absorption spectra reveal that these molecules have infrared transparent regions and are novel nonlinear molecules. Therefore, linking nitro-thieno[3,2-b]thiophene with fullerene (C20) efficiently designs high-performance nonlinear molecules.

في هذا البحث تم دراسة تأثير متغير الدوران والمتغيرات الأخرى على التدفق التمعجي لسائل سوتربي في قناة غير متماثلة مائلة تحتوي على وسط مسامي مع انتقال الحرارة. في وجود الدوران، تم تطوير النمذجة الرياضية باستخدام المعادلات الاساسية القائمة على نموذج سائل سوتربي. في تحليل التدفق، يتم استخدام افتراضات مثل تقريب طول الموجة الطويلة وانخفاض عدد رينولدز. تم حل المعادلة التفاضلية الاعتيادية غير الخطية الناتجة تحليلياً باستخدام طريقة الاضطراب. يتم تحليل تأثيرات رقم كراشوف، ورقم هارتمان، ورقم رينولد، ورقم فرود، ومعلمة هال، ورقم دارسي، والمجال المغناطيسي، ومعلمة سائل سوتربي، وتحليل نقل الحرارة على وظيفة التدفق وتدرج الضغط بيانياً. باستخدام برنامج ماثيماتيكا، تم حساب النتائج العددية. تم اكتشاف أن حجم الفقاعات يتناقص مع زيادة بعض المعلمات ، بينما يتناسب تدرج الضغط تناسب طردي مع غالبية المعلمات.
