Abstract
A prominent characteristic of the trial discourse is the imbalance of power between the participants, in such a way that the power is imposed unilaterally from the interrogator (be it the investigator, the judge, etc.) to the addressee. The most important tool for imposing power is the use of "question" which has a controlling feature. In order to analyze the different dimensions of the trial discourse, the present research studies the structural, discursive and pragmatic aspects of questions in different criminal, civil and family branches in the court and prosecutor's office of Duroud city. In the structural dimension, the types of morpho-syntactic characteristics and in the pragmatic dimension, the type of speech act of different types of questions have been considered. In this regard, we examined the data by combining quantitative and qualitative approaches. The results indicate that the most frequently used question forms are related to yes/no and narrow wh-questions. It was also found that the questions have three types of regulative, constative and communicative speech acts. The findings confirm that some questions that have a communicative action are raised by lay participants with the purpose of clarification, and therefore, in some situations, it is possible to observe a change in the one-sided questioning pattern of interrogator → addressee. Most of the questions that are raised by lay people are rooted in their lack of familiarity with technical legal terms, which in some cases can lead to consequences such as the lack of a favorable defense.

Abstract
This study attempts to evaluate one of the language use differences among women and men according to the Dominance Theory. The main purpose of the study is thus to investigate speech interruption as the participatory dominance factor based on the Dominance Theory in the Persian community and three affecting factors on interruption (direct statements, subject deviation and verbs and adverbs of uncertainty). Speech interruption and three affecting factors on interruption have been evaluated in the single and cross-sex societies. The data required were obtained from 40 two-stage interviews (10 men and 10 women students in the age range of 18-24 years). The men and women of this study in single and cross-sex societies, based on speech interruption factor, showed different linguistic behaviors and the linguistic representation of gender-based attitude in the Persian community was tangible. The relationship of each affecting factor on interruption with interruption was determined. The findings suggest that the framework provided by Dominance Theory in Persian community is inefficient.

Abstract
The present study was conducted in the central region of Khyber Pakhtunkhwa (KPK), Pakistan comprising seven districts: Peshawar, Charsadda, Nowshera, Mardan, Swabi, Kohat and Hangu, during 2010. The objective was to analyze the perceived effect of Farmer Field School (FFS) approach on farmers’ capacity in controlling pre- and post- harvest losses. Descriptive statistics were used to analyze the data collected from 280 randomly selected farmer respondents. The analysis revealed that FFS had remarkably built up farmers’ capacity in controlling pre and post-harvest losses caused by rodents, birds, immature harvesting/picking, and inappropriate packing, storing, and transportation of the produce. Furthermore, FFS helped farmers in reducing losses at the market and controlling grain borer, wheat weevil, and store weevils effectively. The study concluded that the highest improvement as a result of FFS activities was in controlling losses by rodents, proper packaging and labeling of the produce, and controlling some stored grain pests like grain borer and wheat weevil. By and large, farmers’ capacity was built up in almost all aspects of controlling pre- and post-harvest losses, except a few i.e. losses due to immature harvesting of crops, and controlling losses caused by store insects, which needed special focus of the authorities concerned.

Abstract
Controlling the gas turbine emissions has led the manufacturers to use new technologies. Nitrogen oxides (NOx) are one of the major pollutants of gas turbines with natural gas as fuel. Thermal NOx is the main cause of NOx formation in gas turbines at high temperatures. So, water injection can be useful in reducing the NOx emission. In addition to NOx reduction, water injection causes an increase in carbon monoxide emission and damage to combustion chamber. Therefore, it is desirable to find the optimum amount of water injected to the combustion chamber to meet the regulations. To find the optimal water mass flow rate, we numerically investigated the combustion inside the chamber for full load and part load before and after water injection. Then, the effect of water injection at different flow rates was studied to obtain optimal water flow rate. The results showed that for the full load, the optimal water flow rate was 100% of the fuel flow rate and the upstream pressure of the feed water system was 24.45 bar. For the part load (fuel flow rate equals to 75% of the full load), the optimum water injection rate is 80% of the fuel flow rate. In this case, the pressure required for water injection is about 16.5 bar. Results also show that the change in water temperature in the range of 10-80˚C has no significant effect on NOx formation and water can be injected at the ambient temperature.
