Arabic gum (AG) was used as both the reductant and steric stabilizer without any other surfactant. By adjusting the reaction temperature, mass ratio of AG to AgNO3, and reaction time, silver nanoparticles with different morphological characteristics could be obtained. The products were characterized by UV-Vis, FTIR, TEM, SEM, and XRD measurements. It was found that temperature and AG played an important role in the synthesis of mono-disperse silver nanoparticles. Well dispersed and quasispherical silver nanoparticles were obtained under the optimal synthesis conditions of 10 mmol/L AgNO3, m(AG)/m(AgN03)= l:1, 160 ℃ and 3 h.展开更多

METHODS: A total of 1357 students were randomly selected between the ages of 16 and 18 years (689 males and 668 females) from three different regions of Saudi Arabia (Madinah, AI-Qaseem, and Aseer) and tested for anti-HAV-IgG.RESULTS: The overall prevalence of anti-HAV-IgG among the study population was 18.6%. There was no difference between males and females but there was a significant difference in the seroprevalence (P = 0.0001) between the three different regions, with Madinah region showing the highest prevalence (27.4%). When classified according to socioeconomic status, lower class students had a prevalence of 36.6%, lower middle class 16.6%, upper middle class 9.6%, and upper class 5.9% (P = 0.0001). Comparing the current study results with those of previous studies in 1989 and 1997 involving the same population, there was a marked reduction in the overall prevalence of HAV from 52% in 1989, to 25% in 1997, to 18.6% in 2008 (P 〈 0.0001).CONCLUSION: Over the last 18 years, there has been a marked decline in the prevalence of HAV in Saudi children and adolescents. The current low prevalence rates call for strict adherence to vaccination policies in high-risk patients and raises the question of a universal HAV vaccination program.展开更多

The study is based on a sample survey covering 600 youth cohorts in Yanbu and Jeddah in the Kingdom of Saudi Arabia. The study reveals that school-to-work transition is not a smooth one and is influenced by the perception of youth towards employment and its various dimensions along with the ambitions towards career improvement. The 14 indicators framed in the paper reveal that essentiality, confidence to get a job that satisfies the needs, job availability, and qualifications are found to be important determinants of youth's attitude towards work; whereas, willingness to do any job did not get much acclaim. Job selection of youth is determined by location (especially hometown job), sectoral preferences, training options, and work environment.展开更多

The sample of the study consisted of 266 high school graduates Jordanian students in the academic year 2013-2014. A translation test consisted of 24 items and divided to eight areas was constructed to arrive at the objectives of the study. The study concluded that the percentage of total errors committed by the study sample in all areas exceeds percentage of correct answers (wrong answers is 52.48'%, correct answers is 47.52%), and the students committed more transfer errors in the types of verb to be, addition to, andpassive voice than other types of errors as a result of the effect of the L1.展开更多

The findings indicate that all the resources that were examined contribute to reducing the level of depression; in other words, significant negative correlations were found between the level of religiosity, happiness, social support and self-control on the one hand, and the level of depression on the other hand. These findings are consistent with those of other studies conducted elsewhere in the world on different populations CChristian and lewish, as well as Muslim). The present study and its findings are, however, the first to address the understanding of depression among the populace in question. The findings were discussed in accordance with a number of different theories.展开更多

We shall attempt to answer a number of questions concerning Arab Spring literature in general and the video clips in particular: What role did this literature plays in the political transformations witnessed by the Arab world in recent years? What are the means it used in order to inflame the masses? What are the features of the Arab Spring video clips as a new genre different from printed genres? Will the Arab Spring continue to be a literary theme after the end of these uprisings? These clips possess rich and dense semantics content and meaning as it will be shown in this article.展开更多

This research will describe how the teacher used some Arabic language methods as a teaching strategy to improve her EFL students' reading, writing, and understanding of English grammar. The research took place over a period of two years in Lebanon and four years in Saudi Arabia. Data consists of comparative tables, videos of two samples of students using Arabic to learn English, and pictures of the teacher using Arabic for comparative in grammar. Results revealed an increase in the level of understanding and comprehension of students in both the elementary and intermediate levels.展开更多

To achieve the purpose of the study, the researcher used an experimental design: an experimental group and a control group. The independent variable is using L1 while teaching English in very limited and specified areas. The dependent variable is students' achievement in general English. The statistics used is the t-test. The population of the study was all students enrolled in the foundation year 1431/1432 in the ELI (English Language Institute) at King Abdulaziz University. The sample of the study consisted of 50 students taking North Star in the sections A and B as a university requirement in the foundation year 1431/1432 in King Abdulaziz University. The results of the study were in favor of banning Arabic in the English language classroom as shown in the mean scores of the control and experimental groups in the tables. It is recommended that teachers and instructors should be trained to use teaching strategies that help them use English only in the English language classroom.展开更多

The programme is managed by an American company called Interlink and is entirely staffed by native English teachers. The implementation of this English instruction encompasses motivational, pedagogical, and administrative challenges that hinder its practicality for positive and achievable learning outcomes. To this end, this paper will attempt to address the sociolinguistic and historical profile of EFL in Saudi Arabia in order to present an overall picture of this study's context.展开更多

Since writing in English is a challenging experience for Omani students, errors in grammar and sentence structures were identified in bridging language courses (foundation level 2) in the field of ESL (English as a Second Language}. Learners' errors were considered positively as the best sources to identify students' limitations in English writing. The present study investigates the structure errors of Omani students' writings in English in foundation level 2 at Arab Open University. The focal aim is to study the errors that Ornani students commit when they are using adjectives + nouns, indefinite articles, and subordinate conjunction "because". Results show that Omani students committed the following common errors: misplacement of adjectives, omission of the indefinite articles, and wrong structure of the subordinate conjunction (because). The prime aim of this study is to examine the students' aforementioned structural errors which are the result of the interference of their mother-tongue. In order to achieve these aims, students were asked to write two different topics. Finally, this research suggests further recommendations for further studies which might ameliorate students' learning by adopting appropriate strategies for teaching.展开更多

Apparently, there was no pattern to these errors. However, when the researcher observed the frequency of similar error over a few years of her experience as an EFL faculty for Saudi learners, the theory of Lexical Relations appeared to offer an answer. Therein also lies the genesis of the current study. In a positive development, the study did bring to light certain factors that directly played a role in the Saudi EFL learners' English errors. These have been presented in this paper with the hope that with the diagnosis in hand, it will be easier for the EFL teachers to find a solution to the dearth of English proficiency among the Saudi EFL learners.展开更多

The literature reflects their love of Algerian culture and thought, and their revolt against French colonialism. The Algerian-born Arab author Muhammad Dib (1920-2003) wrote in French, mainly about the Algerian struggle for independence. Expelled in 1959 for supporting the Algerian revolution, he settled in Paris. Considered a pioneer of Algerian literature, he was the first Arab Algerian to write Western-style novels. His Algerian trilogy, La Grande Maison, L 'lncendie, and Le Mktier ~ tisser, was published between 1952 and 1957. Though autobiographical, the books trace both rural and urban life in pre-revolutionary times. Dib's 1959 thematically driven novel Un Otd Africaine (An African Summer), analyzed here, rather than depicting the Algerian revolution itself, describes its effect on the characters and their lives. Nevertheless, the novel, framed around a cross-section of Algerian society, reflects colonial government abuses and the common people's sacrifices for their dream of independence. Dib also depicts France's colonialist attitudes as a betrayal of the ideals of the French Revolution and claims to humanitarian values.展开更多
文摘Finely divided silver nanoparticles were synthesized via the hydrothermal method. Arabic gum (AG) was used as both the reductant and steric stabilizer without any other surfactant. By adjusting the reaction temperature, mass ratio of AG to AgNO3, and reaction time, silver nanoparticles with different morphological characteristics could be obtained. The products were characterized by UV-Vis, FTIR, TEM, SEM, and XRD measurements. It was found that temperature and AG played an important role in the synthesis of mono-disperse silver nanoparticles. Well dispersed and quasispherical silver nanoparticles were obtained under the optimal synthesis conditions of 10 mmol/L AgNO3, m(AG)/m(AgN03)= l:1, 160 ℃ and 3 h.
