to high degrees in the axes of the questionnaire as a whole, most of the responses that were reached
were between the large and the very large, except for one phrase that came to a medium degree,
which is: The school administrations have independent budgets to deal with crises and pandemics,
and related to the competence of planning. in terms of the arrangement of competences, they came in
a row: The competence of follow-up with an arithmetic average (4.21), the competence of
communication with an arithmetic mean (4.15) competence of organization with arithmetic average
(4.11) competence of leadership with arithmetic average (3.98) competence of planning with
arithmetic average (3.81) The study confirmed that there are no statistically significant differences in
all the axes of the questionnaire, according to the variable of gender and the variable of educational
qualification, the study recommends the need to follow up the situation up-to-date and motivating

The Effectiveness of Blended Learning based on digital games in increasing students' motivation toward learning mathematics
هدفت الدراسة للكشف عن فاعلية استخدام التعلم المدمج القائم على الألعاب الإلكترونية في زيادة دافعية طلاب الصف الخامس نحو تعلم الرياضيات، استخدم الباحث المنهج الشبه التجريبي. وبلغت عينة الدراسة 76 طالباً من طلاب الصف الخامس الأساسي من مدرسة الإمام الحسن بن سعيد السحتني للتعليم الأساسي للبنين (5-12) بسلطنة عمان. ولإجراءات الدراسة تم اعداد برنامج تعليمي قائم على الألعاب الإلكترونية، ومقياس دافعية الطلبة نحو تعلم الرياضيات. توصلت الدراسة الى وجود فروق ذات دلالة إحصائية لصالح التطبيق البعدي لمقياس الدافعية نحو تعلم الرياضيات، حيث بلغ المتوسط الحسابي للمقياس في التطبيق القبلي (2,73)، وفي التطبيق البعدي بلغ المتوسط الحسابي (4,13)، أي بفارق وقدره (1,4) لصالح التطبيق البعدي. وفي ضوء نتائج الدراسة أوصى الباحثين بعدة توصيات أهمها تشجيع المعلمين على استخدام التعليم المدمج القائم على الألعاب الإلكترونية لما له من دور في تحسين دافعية الطلاب نحو تعلم الرياضيات وكذلك عمل أنشطة متنوعة وتفاعلية للطلاب عن طريق الألعاب التعليمية الإلكترونية، ومن المهم كذلك عقد دورات ومشاغل تدريبية لمعلمي الرياضيات تهدف إلى تطوير ممارساتهم التدريسية.This research is action research aimed to reveal the effectiveness of using blended learning based on digital games in increasing the motivation of grade-five students towards learning mathematics. The quasi-experimental method was used with thirty-eight grade-five students in Imam Al-Hassan bin Saeed Al-Sahtani Basic Education School for Boys (5-12) in the Sultanate of Oman. The study used two instruments; an educational program based on digital games and a scale of students' motivation toward learning mathematics. The study found that there were statistically significant differences in favour of the post-motivation scale, in which the mean of the scale in pre-motivation scale was 2.73 and the mean of the post-motivation scale was 4.13. There was a difference of 1.4 in favour of the post-motivation scale. Considering the results of the study, the researchers recommended encouraging teachers to use blended education based on digital games and making various interactive activities for students through instructional digital games
Factors influencing poor academic performance among urban university students in Bangladesh
Poor academic performance is challenging for students, parents, and teachers. This cross-sectional study aimed to determine the factors associated with the poor academic performance of 661 undergraduate students who scored CGPA ≤2.5 from a selected private university of Dhaka City, Bangladesh, using a simple random sampling technique. Data were collected using a pretested and self-administered questionnaire. Of the study participants, male preponderance (88.4%) was found, and 77.9% of them selected the study programs by themselves. Poor academic performance was found significantly correlated with irregular class attendance (p=0.003), father’s low education level (
Enhancing the Quality of "Produced Water" by Activated Carbon
The main objective is to contribute via this study, in solving an environmental issue and helping Qatar in finding suitable water resources; useful in agriculture. Qatar faces diverse water challenges; the number one that threats here is scarcity as water is not renewable. Due to scarcity of good quality water, reusing of low quality and contaminated water is highly increasing in Qatar. The main source of water in Qatar is desalination stations. Most of the desalinated water is for human usage. Agriculture in Qatar depends mainly on underground water; it is available but always saline and found in insufficient quantities. Due to the increasing demand for water among industries and irrigation, using other alternative water resources such as produced water during oil and gas extraction would be of importance. Generally, produced water is the water that exists in subsurface and is moved to the surface through oil and gas processes. The volume of produced water and pollutants concentration vary depending on the nature and location of the oil products. It represents the major waste stream related to oil and gas processes. Large volume of produced water generated in Qatar has the potential to enhance the water resources. The crucial goal of produced water management is to eliminate dissolved harmful components and use it for beneficial uses that can efficiently improve environmental impact and water shortage. An exclusive characteristic of produced water comparing to other wastewater resources is the large variation and complexity in water chemistry. This would play a vital role in the remediation processes.qscienc
USE OF MORE THAN ONE FORM OF TOBACCO AMONG THOSE FROM A LOW SOCIOECONOMIC BACKGROUND IN BANGLADESH
Tobacco has negative public health consequences. In this study we aimed to determine the prevalence of and factors associated with using more than one form of tobacco among people from a low socioeconomic background in Bangladesh in order to inform tobacco control and prevention programs for this population. Inclusion criteria for study subjects were current tobacco users, aged >= 15 years who were able and willing to participate. Study subjects were selected randomly from two industrial areas. An enumeration survey was conducted prior to actual data collection to identify the low income population by sex. Exclusion criteria for study subjects were age >65 years and being a temporary migrant. The number of subjects calculated to be needed for the study was 460. Each subject was asked to complete a semi-structured questionnaire that asked about sociodemographic characteristics, use of tobacco and types and potential associated factors. Descriptive statistics were used to summarize sociodemographic characteristics, a chi-square test and Fisher's exact test were used to determine associations between selected factors and tobacco use and logistic regression analysis was used to identify factors associated with using more than one form of tobacco. A total 460 subjects were included in this study 50% were males. The mean age of study subjects was 43.3 years. The most common occupation was housewives followed by service. Of the 460 subjects, 23% used more than one form of tobacco: 97.1% of them male subjects and 2.9% of female subjects. Use of more than one form of tobacco was significantly (
