Antibacterial properties of Cu-ZrO2 thin films prepared via aerosol assisted chemical vapour deposition

© 2015 The Royal Society of Chemistry. The antibacterial properties of a Cu-ZrO2 film grown via aerosol assisted chemical vapour deposition are presented. The composite film showed high activity against E. coli (Gram-negative) and S. aureus (Gram-positive) bacteria with 5 log10 (E. coli) and 4 log10 (S. aureus) decrease in viable bacteria achieved within 20 and 60 minutes respectively. These results were comparable to a pure copper film that was prepared under the same conditions. The composite film was characterized for material properties using a range of techniques including X-ray photoemission and X-ray diffraction

Psychological Predicates and Verbal Complementation in Arabic

The issue of verbal complementation patterns in the Arabic vernaculars isone which is relatively under-researched: this paper aims to make a small con-tribution in this area, focussing on essentially two issues (i) the syntax of so-called experiencer-object psychological predicates (EOPVs) (that is, predicates in the frighten or please classes) and (ii) the syntax of aspectual or phasal pred-icates (that is, verbs such as begin and continue). We argue that the latter classof verbs are in fact raising verbs and go on to show that in some dialects the interaction of EOPV and aspectual predicates permits a pattern reminiscent of Copy Raising

An Analytical assessment of Lean Manufacturing Strategies and Methodologies Applied to Kuwait Oil Company (KOC)

Effluent water is one of the significant volume waste streams in the industry of oil manufacturing; this report addressed the effluent water management in the Kuwait oil Company (KOC). A Research methodology adopted quantitative and qualitative analysis, in order to focus on the difficulties and barriers facing the process of effluent water management, it may be abridged that the parts of effluent water have an alternate possible effect on the surroundings. Subsequently, decreasing these segments, particularly the destructive ones, all together to achieve the most reduced level regarding diminishing the rate released with generated waste water, is the essential objective of the oil manufacturing industry, Due to effluent water disposal & injection practice which is being carried out at KOC can be observed some problems can be summarized as The water cut (W/C) in oil wells start increasing dramatically after water injection back to the reservoir which reduces the oil rate productivity of the wells, Scaling issue in the flow lines start taking place recently at KOC which also reduces the productivity of the wells and need some costly projects to resolve it., There is a great impact on the integrity of our facilities (corrosion issues) . It has been observed that the salinity of the brackish water which is produced from artesian wells is increasing dramatically as well due to effluent water disposal into shallow layers underground

Quality Assessment of English Teaching at the Newly Established Universities in Saudi Arabia: Shaqra University as a Case Study

As the case world-wide, the English language is central in Saudi schools and universities. Despite its prominence, students’ level of English language proficiency is generally believed to be unsatisfactory. This study explores this issue by investigating the quality of teaching with reference to the extent to which professors do employ the course assessment methods of learning domains specified in the course specifications template, provided by the National Commission for Academic Accreditation and Assessment in Saudi Arabia, as one of the main factors for improving teaching processes. To this end, 12 courses in the English BA program at Shaqra university, a newly established university in Saudi Arabia, were investigated. The results have shown a significant problem in the quality of teaching English language. First, the learning domains, i.e. Knowledge, Cognitive Skills, Interpersonal Skills, were barely seen in the exam papers. Second, the methods of assessments specified in the course specifications were moderately used by instructors. The study closes with some suggestions for future investigations

An Enhanced AdaBoost Classifier for Smart City Big Data Analytics

The targeted goal regarding the smart cities is improving the goodness of their people and to raise the economic improvement in maintaining certain rate or level. Smart cities would increase all set of utilities, which involves healthcare, education, transportation and agriculture among other utilities. Smart cities are depended on the ICT framework, which includes the Internet of Things methodology. These methodologies make bulk of diverse in data, which referred to as big data. Moreover, these data have no purpose by themselves. Modules needed to improve as new to explain the large amount of data collected and one of the good methods to solve is to use the methods of big data analytics. It shall be maintained and designed through the methods of analytics to get good understanding and in order to increase the utilities of smart city

Using Repeated Reading and Previewing Vocabulary Interventions with Elementary-Aged Struggling Readers to Improve Fluency and Comprehension

Students with Learning disabilities and at risk for reading difficulties often face challenges in reading fluency and comprehension that impact negatively on academic success. Repeated reading (RR) is an intervention designed to increase reading fluency and comprehension skills among students at risk and diagnosed with disabilities. The purpose of this review was to investigate the effectiveness of the repeated reading (RR) and vocabulary previewing (VP) interventions on the fluency and comprehension skills of elementary school students. The review yielded a modest number of research articles published between 2008 and 2019. The results of these studies suggested that RR can have a positive effect on reading fluency and comprehension skills of students at-risk and those with identified learning disabilities. Discussion includes limitations of the RR intervention, implications for future research, and classroom practice
