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

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

An exploration of authorial stance in SSCI-ranked journals versus non-SSCI-ranked journals

Taking an effective authorial stance has been the interest of researchers on academic writing for quite some time. It is agreed upon that the interpersonal aspect of writing is essential in setting up prosody and forcing persuasive argument expected in academic context. This paper is based on a hypothesis that effective and authorial stance is a major principal requirement for publishing in top-ranked journals. Hence, it investigates the linguistic resources employed by authors to realize authorial voices when introducing their research topics and how they relate them with the potential meanings of rhetorical moves to build up persuasive argument. To do this, the study drew on Martin and White's (2005) Appraisal system and Swales' (1990) genre analysis as the two main analytical frameworks for data analysis. The data consisted of sixty research articles (RAs) taken from journals in the linguistics field. Half of the RAs were drawn from SSCI-ranked journals while the other half from other journals that do not have prestigious indexes. The results showed that the percentage of using Monoglossic resources (propositions that contain bare assertions where writer/speaker makes no reference to any alternative viewpoints) is higher in frequency in non-SSCI journals compared to SSCI-ranked journals. Overall, the introduction sections of the two groups of journals have shown a link between the use of evaluative language patterns and the potential meanings of rhetorical moves, which altogether may help project effective authorial stance

Efficacy of tamoxifen and thymoquinone on tumor development, lipid peroxidation, and total antioxidant capacity in DMBA induced mammary carcinoma in female Sprague-Dawley rats

Tamoxifen (TAM) is a drug used for treatment and prevention of breast cancer. However, TAM has been reported to induce liver tumors in several animal models due to overproduction of free radicals and lipid peroxidation. Thymoquinone (TQ), from Nigella sativa seeds, is a Middle East natural medicine and it has been used to treat a number of diseases, including cancer. The aim of my study was to investigate the effect of TQ and TAM on tumor development, lipid peroxidation level, and total antioxidant capacity in DMBA treated female Sprague-Dawley rats. Five groups of 10 rats (control, DMBA, TAM, TQ, and TAM+TQ) were used. Mammary tumors were induced by DMBA which was given by oral gavage to four groups: DMBA, DMBA+ TAM, DMBA+ TQ, and DMBA+ TAM & TQ. The control group received tap water only. Starting three weeks later, TAM and/or TQ were administered daily for 10 weeks. Mammary tumors were found in two DMBA treated animals. There was coloration in the mammary glands in four other DMBA treated animals. No mammary tumors or mammary gland coloration was observed in other groups. Rats treated with TAM showed a significantly higher level of lipid peroxidation when compared to control (

The Experimental Investigation of The performance of Phosphor Coating

Different screen printing parameters have a distinct effect on the quality of coating that is created. This experimental work looked to measure these parameters. It is divided into two parts where the first part measured the surface wettability of various substrates Wettability measurement was performed through measuring the contact angle between the droplet and the substrate surface. Varying the UV exposure time by putting substrate in the UV ozone cleaner has a considerable effect on the wettability of the surface. Water was supplied to a PEDOT: PSS substrate via Fibro DAT 1100 which is attached to a camera and a computer for capturing and analyzing coatings for the spread of a water droplet on the substrate surface. From these analyses, the main aim is to measure the contact angle between the droplet and the substrate surface which indicates the surface wettability. Some factors may affect the wettability of the surface such as varying the UV time and varying the hold time. As a result, increasing these times will decrease the contact angle where a small contact angle indicates a favorable wettability. The second part measured the electrical resistance and transparency of the printed ink after various printing experiments such as implementing UV treatment, changing the ink and changing the mesh ruling. The Rheometer device was used to test the properties of the specimen. Where this device can be used to measure the properties of the specimen such as the shear modules, in this paper the plate was used to effect on the specimens, where different readings are recorded for these specimens. Also, 24 samples were prepared and the electrical resistance for these samples was measured in this paper. As a result, the electrical resistance for treated samples was greater than that for untreated samples; the electrical resistance of Elentan ink was greater than that for PEDOT at the same conditions. Changing the screen size from (61-64) to (40-100) increase the value of resistance at the same conditions. For the transparency measurements the Elentan ink had a higher transparency than PEDOT ink. The paper also carried out an analysis for the relation between the thickness of the phosphor layer and the lamp output, where the relation was inversely proportion

Tobacco Smoking Among Saudi College Students: Validation of an Arabic Health Belief Model Instrument

This dissertation intended to learn more about Saudi college students\u27 behavior in relation to the use of tobacco smoking. Multiple interrelated projects have been carried out in order to achieve this ambitious goal. The goal of the first study was to evaluate the scope of the existing smoking issue as indicated by research, by systematically estimating the prevalence of tobacco use among higher education students in Saudi Arabia. The second study aimed to systematically analyze and integrate the existing information on the determinants of smoking among Saudi college students. The last project aimed to develop a psychometric instrument to evaluate Saudi students\u27 beliefs about cigarette smoking based on a theoretical model. The meta-analysis (Project 1) estimated that the 17% of Saudi students were current smokers. In order to obtain a reliable prevalence rate over time, the study suggested implementing a nationwide surveillance system that measures and monitors Saudi students’ smoking behaviors. The second systematic review (Project 2) determined that individual level factors were the most studied. Another finding was the limited usage of theoretical frameworks. The study advocated for the use of rigorous research methodologies and for the use of multi-level frameworks. The final project (3) was intended to generate and to validate a psychometric property to evaluate students’ beliefs about cigarette smoking, using an individual level framework. The Arabic Health Belief Model questionnaire demonstrated its sound validity and reliability. Future research is encouraged, in order to expand knowledge about smoking behaviors among college students in Saudi Arabia
