Autism Spectrum‌ Disorder‌ (ASD) is characterized by deficits in social communication and repetitive behaviors or restricted interests. The ability to communicate verbally is considered a positive prognostic indicator of outcomes for children with ASDs. One of the major problems in autism is the sensory processing deficit, and in particular the abnormalities of auditory processing. Therefore, the purpose of the present study was to determine and investigate the correlation between auditory processing ability and verbal output of children with autism spectrum disorder.

The present analytical descriptive correlation study was conducted in 2018. The statistical population of the research was children with autism aged 4 to 7 years from speech therapy centers in Tehran, and 40 qualified volunteers were included in the study. To collect related data, the following standard tests were used: the childhood autism rating scale for screening and diagnosing children with autism from the age group of two years and older which had 15 items, and Fisher's auditory problems checklist with 25 items. The collected data were analyzed using the Poisson regression test.

The results of the present study indicated that there was a correlation between auditory processing ability and verbal output of children with autism spectrum disorder who participated in this study (p=0.46). Moreover, considering different levels of auditory processing, between auditory processing ability and output Verbal correlation was observed only at the level of high auditory processing ability (p=0.43). [

The results of this study showed that the ability of auditory processing was an important factor for development of verbal output in children with ASD. Early screening and intervention of auditory processing impairments in these children can facilitate the rehabilitation programs.

Environmental pollutants such as soot, nitrogen oxides, and carbon monoxide are the main demerits of fossil fuels. Therefore, it is imperative to control the air pollutants in order to provide a clean and pleasant environment. In the present study, the effects of temperature, mass flow rate of the injected fuel, pore diameter, porosity and ambient pressure on the amount of pollutants are investigated in the combustion chamber. The combustion process is numerically simulated by employing Species Model at species transport mode of operation. Discrete Phase Model is used to predict flow field behavior by considering the interaction between liquid and gas phases. Also, the flow is simulated under turbulent regime with the diffusive flame in the combustion process. Results show that increasing the heat transfer in porous medium leads to the decrease in the gas temperature and NOX formation. The production of unburnt hydrocarbon species like carbon monoxide decreases due to a better pre-heating process in the porous medium. Increasing the diameter of pores slightly reduces the amount of carbon monoxide, while the amount of nitrogen monoxide surges up.

It seems that the main source of smartphone addiction in teenagers and young adults is environmental stress such as school and family; The present study was conducted with the aim of smartphone management styles and smartphone addiction: the mediating role of hot executive functions in students.

The research method is cross-sectional correlation. The statistical population of this study consisted of all students of normal schools for boys and girls aged 15 to 18 years living in Tehran in 1399-1400, from which 722 people were selected by available sampling method. In this study, mobile dependency tools (Bianchi and Phillips, 2005), smartphone management styles (Hsieh et al., 2019) and executive functions (Balster Gerrard et al., 2000) were used, all of which have valid credibility and reliability, they were accepted. SPSS-V24 and Amos-V8.8 software were used to analyze the data.

Structural equation modeling was also used to answer the research hypotheses. Findings showed that the model has a good fit. The results also showed that the direct standard path of smartphone management on smartphone addiction is indirect and significant (P=0.05).

The results showed that the effect of direct standard of smartphone management on phone addiction is significant and the effect of indirect standard of smartphone management on phone addiction with the mediating role of hot executive functions is significant. Therefore, paying attention to the mentioned variables in prevention and designing more appropriate therapies will help researchers and therapists.

Diabetes mellitus is one of the most important chronic diseases which is substantially increasing in the world especially in developing countries. Nowadays changes in life style, inadequate diabetic habits, sedentary life and obesity are among the most significant causes of type 2 diabetes. Increase in general population knowledge can greatly reduce the expansion of the disease and progression of its complications. The aim of the present study was determine population knowledge of diabetes mellitus in Ahvaz.Subjects and

This was a descriptive cross-sectional study on 400 visitors of Simorgh exhibition of Ahvaz University of Medical Sciences which was held during the 10 days of Fajr in 2009 were the subjects of this study. Data were collected by a questionnaire and analyzed by chi-square test with SPSS.

The awareness of diabetes amont Ahvazians was good in 36.8 %, at intermediate level in 44.2 % and weak in 19 % of the subjects of the study. Average age of participants was 31years.Women's knowledge was more than men (P
