The organization and coordination of any communication is based on the system of turn-taking which refers to the process by which a participant in a conversation takes the role of speaker. The progression of any conversation is achieved by the change of roles between speaker and hearer which, in its turn, represents the heart of the turn-taking system. The turn-taking system is not a random process but it is a highly organized process governed by a set of rules. Thus, this system has certain features and rules which exist in any English communicative process. These rules, if applied by speakers, help to achieve successful exchange of turns in any conversation. This paper attempts to present full exposition of the concepts of conversation, conversation analysis and institutional talk. This is the subject-matter of section one. In the second section, a comprehensive theoretical background of turn-taking system has been presented. The paper mainly aims at making detailed analysis of the Turn-taking system in the American Presidential Debates. The analysis is done in the third section by investigating and examining the corpus which consists of three American Presidential Debates chosen randomly. These debates are: 1. Republican presidential candidate debate in Simi Valley, California January 30, 2008. 2. Republican presidential candidate debate in Washington, DC November 22, 2011. 3. Republican presidential candidate debate in Des Moines December 10, 2011. The three debates have been downloaded from the internet from the website http://www.presidency.ucsb.edu/debates.php. In each debate, there are a number of presidential candidates who have different political orientations. The analysis is presented through certain points supported by statistics and examples which are in the form of quoted extracts chosen from the three debates analyzed. Section four is devoted for presenting the conclusions arrived at throughout conducting the analysis of the three debates.
Background: Optimal root canal retreatment was required safe and efficient removal of filling material from root canal. The aim of this in vitro study was to compare the efficacy of reciprocating and continuous motion of four retreatment systems in removal of root canal filling material. Materials and Methods: Forty distal roots of the mandibular first molars teeth were used in this study, these roots were embedded in cold clear acrylic,roots were instrumented using crown down technique and rotary ProTaper systemize Sx to size F2 ,instrumentation were done with copiousirrigation of 2.5% sodium hypochlorite and 17% buffered solution of EDTA was used as final irrigant followed by distilledwater, roots were obturated with AH26 sealer and Prota
... Show MoreThe result showed that hot water and ethanol extracts of Nigella sativa contain alkaloids ,saponins, flavonoids,tannins,glycosides,terpins and steroids. Albino mice were administered orally with 0.1 of the extract at dose of 100 mg/kg, body weight the results showed high level of white blood cell ,total and differential count of WBC,phagocytosis index, mitotic index, Arthus and delayed type hypersensitivity. The result, also showed high level of hemoglobin (Hb) and the packed cell volume (PCV) the alcoholic extract has been found more efficient than hot water extract on mice.
The research study of the possibility of the application of the quality management system under the international standard ISO ISO9001: 2008 in the station project Rustumiya wastewater treatment of the Department of SEWER BAGHDAD - Baghdad MOREALITY as the first step in the right direction towards the implementation of total quality management (TQM), and the research Find the gap between the international standard and the quality system used in the organization surveyed through the use of checklists to analyze the gap, the checklist have included (191) items distributed on five basic requirements, according to the appearance in the international standard, namely, (quality management system, management responsibility, resource man
... Show MoreReducing global warming potential (GWP) of refrigerants is needed to the decrease of ozone-depleting of refrigeration systems leakages. Refrigerant R1234yf is now used to substitute R134a inside mobile air conditioning systems. Thermodynamic properties of R1234yf are similar to R134a. Also, it has a very low GWP of 4, compared to 1430 for R134a, making it a proper choice for future automobile refrigerants. The purpose of this research is to represent the main operating and performance differences between R1234yf and R134a. Experimental analysis was carried out on the automotive air conditioning system (AACS) with 3 kW nominal capacity, to test and compare the performance of R134a with R1234yf. Experiments were accomplish
... Show MoreA new colorimetric-flow injection method has been developed and validated for the detection of Cefotaxime sodium in pharmaceutical formulations. This method stands out for its rapid and sensitive nature. The formation of a brown-colored complex between Cefotaxime sodium and the Biuret reagent in a highly alkaline environment serves as the basis for the detection. The intensity of this colored complex is measured using a custom-built Continuous Flow Injection Analyzer, enabling accurate quantification of Cefotaxime sodium. Optimization studies of the chemical and physical parameters such as dilution of Biuret reagent, effect of the medium basicity, flow rate, sample loop and others have been investigated. The calibration gra

This research aims at identifying the effect of problem solving strategy on the achievement of Kurdish language grammer of femal students at the fourth preperatory school. To achieve the study aims , the researcher has chosen intentionally this sample to apply the experiement . The study sample cosists 0f (58) female students distributed randomly on two groups. The experiemental group is taught according to problem- solving strategy and it is (29) female students, while the control group which is also (29) individuals is taught according to the traditional way of teaching . The two groups have been matched statistically in term of age , the academic achievement for the father and mother , intelligence, and the linguistic ability. The exp

The effect of partial substitution for veal with TSP quality, sensory characteristics such as color and homogenizing of the stuffing, taste, flavor, juiciness and overall acceptability was evaluated by taste panel. The obtained results showed that product prepared with replaced 15 and 20% were acceptable by panel taste without significant differences compared to control. The values of taste panel score dropped as the rate partial replacement increased a level of TSP 25 and 30% as compared to control. It can be concluded the possibility of using manufacture
