الملخص
هدفت هذه الدراسة إلى التعرف على أثر جائحة كورونا(Coved19) على الأداء المالي والتشغيلي لقطاع شركات الطيران بالامارات، وذلك بالتطبيق على طيران الامارات احدى شركات مجموعة الامارات، حيث تمثلت مشكلة الدراسة فى أثر جائحة كورونا(Coved19) على الأداء المالي والتشغيلي لشركة طيران الامارات ، ولقد إعتمدت الدراسة على الفرضيات التالية:
- يوجد أثر ذو دلالة احصائية لجائحة كورونا(Coved19) على الأداء المالي لشركة طيران الامارات .
- يوجد أثر ذو دلالة احصائية لجائحة كورونا(Coved19)على الأداء التشغيلي لشركة طيران الامارات.
تم إستخدام بيانات كمية متمثلة في التقارير المالية للأعوام (2019 -2020) – (2020)، وتم استخدام تحليل الانحدار الخطي عبر برنامج التحليل الإحصائي (SPSS) في التحليل، وتوصلت الدراسة إلى نتائج أهمها: بأن هنالك تأثير لجائحة كورونا (Coved19) على الأداء المالي لشركة طيران الامارات، ولكن هذا التأثير لم يصل بالشركة لدرجة الخطر، كما أكدت نتائج الدراسة من واقع التقرير التشغيلي بأن هنالك تأثير لجائحة كورونا (Coved19) على الأداء التشغيلي لشركة طيران الامارات، وذلك في فترة التوقف والتي بدأت في مارس 2020، كما أوصت الدراسة بضرورة قيام الشركة بعد الانتهاء من هذه الجائحة، بالافصاح في التقارير المالية عن دور إدارة الشركة للأداء المالي، كذلك ضرورة قيام الشركة بعد الانتهاء من هذه الجائحة، بالافصاح في التقارير المالية عن دور إدارة الشركة للأداء التشغيلي وتأثيره على العملاء والمجتمع، وأخيراً على الشركة تقييم مدى مناسبة اعداد القوائم المالية على أساس الاستمرارية في الفترة اللاحقة لتاريخ نهاية السنة المالية.

Abstract
This study examined Dubai Islamic Bank and Alhilal Islamic Bank in the United Arab Emirates to discover lease arrangements ending in ownership and their effect on credit portfolio performance. The research problem is lease contracts ending in ownership and their effect on Islamic banks’ credit portfolios. The study develops three hypotheses: Compliance with Islamic Sharia for leasing contracts ending in ownership correlates with Islamic bank credit portfolio performance at a.0.5 significance level. Using lease contracts that end in ownership to increase ROI correlates with Islamic bank credit portfolio performance at a significance level of.0.5. Accounting treatment for leasing contracts ending in ownership affects Islamic bank credit portfolio performance at a 0.5 significance level. SPSS was used to analyse data and conduct the field investigation. According to this, the research found: The bank followed Islamic Sharia for lease-to-own contracts. The bank’s return on investment is higher when leases end in ownership. The bank’s financial statements list all lease-to-own assets. The research proposed that bank management use financial leasing to improve the performance of credit portfolios and increase the volume of investments in lease-to-own mode compared to other financing modes. The report advised that bank management build an accounting system that consolidates bank-owned lease contracts.
Keywords: Contracts ending in ownership, Credit portfolio, Islamic banks.

Abstract
Purpose: The aim of the study was to show the efficacy of phonophoresis in combination with traditional physiotherapy for reducing calf muscle spasticity and tightness in diplegic cerebral palsy patient
Subjects and Methods: The study included 30 patients with spastic diplegic cerebral palsy, with age ranged from 2 to 6 years old, with different grade of MAS 1,1+, divided into two groups. The first group with a mean age (3.87+1.25) years, followed phonophoresis plus traditional physiotherapy training ,3 sessions per week for 8 weeks, the second group with a mean age (4.33+ 1.35) years followed traditional physiotherapy training only,3 sessions per week for 8 weeks. Outcome measures were modified ashworth scale (MAS) that measure spasticity and universal standard goniometer to measure joint range of motion.
Result: A significant improvement was recorded in spasticity control and tightness release of calf muscles in the experimental group.
Conclusion: Phonophoresis in combination with traditional physiotherapy was more effective in reducing mild spasticity and tightness of calf muscle in diplegic cerebral palsy children than using traditional physiotherapy program alone.
Keywords: Phonophoresis – Ankle Plantar – Spastic – Diplegic Cerebral – Palsy Children
“Work environment and its relationship with job satisfaction among nurses in Riyadh region, Saudi Arabia”

Abstract
Purpose: Numerous organizations and businesses underate the importance of employee job satisfaction, without realizing that it is the root of many issues in the workplace. Employees require a distraction-free working environment, conducive to realizing their potential, in order to attain their organizations’ goals. Previous studies have shown that multiple aspects work environment factor—such as remuneration, employee autonomy, working hours, and the communication and relationship between the employees and the employers—have a lasting effect on job satisfaction. Despite various studies on the working environment and the barriers therein, there are limited studies focusing on how nursing professionals’ job satisfaction is affected by their working environment, especially in the locale of Riyadh, Saudi Arabia.
Growth kinetic of multi-metal resistant bacteria under metal stress .
The use of multi-metal resistant bacteria as an alternative to heavy metal removal has become increasingly important in recent years. In this study, the potential growth of nine bacterial isolates on media with four different metals included copper, zinc, nickel, and chromium at 10, 50, and 100 mg/L, individually and quaternary were assessed. The data obtained were analysed to determine the effect of metals on the growth kinetics of the bacterial isolates in metal resistance. The growth kinetics included specific growth rate, doubling time and biomass production rate. Based on these parameters, the ability and selectivity of these isolates to grow under metal stress and produce biomass were determined. Tolerance parameters and performance index of all isolates at different metal concentrations were evaluated. The results showed that nine bacterial isolates were able to grow in culture medium integrated with individual and quaternary metals in all selected concentrations. They showed greater adaptability and resistance of metals with well and different rates. The highest biomass production was achieved with Ni followed by Zn were approximately more than half, while Cu, Cr and quaternary ranging approximately between one-third to half of the biomass produced without metals. B megaterium, S ginsensidmutans and K rhizophila the highest tolerance level and performance index with quaternary selected as multimetal tolerant bacteria. Based on the findings obtained, it is possible to conclude that isolates have potential applicability for further research related to bioremediation of metals and management of contaminated sites with vital methods.
Keywords: specific growth rate, metal stress, kinetic parameters, multimetal resistant bacteria, Heavy metals, biomass production.
Characterization and possibility growth for multifetal resistant bacteria from electroplating effluent to potential metal Nbioremediation
Industrialization increased metal-laden wastewater discharges. Electroplating pollutes wastewater with metals. These toxins affect environmental systems and public health due to toxicity, persistence, and water quality degradation. Electroplating effluent-exposed microorganisms minimise metal contamination. Metal-resistant bacteria settle debris in industrial effluents for bioremediation. Current work isolates and identifies naturally occurring bacteria from electroplating effluents, analyses effluent physicochemical properties, and verifies their ability to resist, thrive on various metals, and combined toxicity of quaternary combinations on isolate survival. 60 bacterial isolates were cultivated on agar plates containing copper, zinc, nickel, and chromium. New metal-resistant species and combinations emerge. Secondary screening identified nine 50mg/l-growing isolates. Morphological, biochemical, and 16S rRNA gene sequencing were performed. MIC, growth kinetic, and combined metals toxicity effects are used to determine multi metal resistance and growth at the highest concentration. Microbacterium paraoxydans, Streptomyces werraensis, Microbacterium arabinogalactanolyticum, Staphylococcus haemolyticus, Bacillus paramycoides, Bacillus megaterium, Sphingobacterium ginsenosidimutans, Kocuria rhizophila, and Sphingobacterium detergens were found. All isolates showed multi-metal tolerance and better growth performance with MICs between 200 and 1200 mg/L. First and control had S- and bell-shaped growth curves with lag, log, saturation, and decline phases. Metals impacted stationary more.
Keywords: Heavy metals, metal resistant bacteria, growth patterns, electroplating effluents, Minimum Inhibitory Concentration, bioremediation.
