Transfer of learning from English course to other contexts is one of the most fundamental objectives of EAP instruction. Providing opportunities to transfer the acquired knowledge from the ESAP writing course to writing tasks of specialized disciplines as well as analyzing students’ perceptions of transfer catalysts and barriers might suggest a foundation for future educational planning. This study examines how engineering graduates learning ESAP assessed the four constructs of learning transfer inventory that might facilitate or inhibit the transfer of learning in discipline-specific academic writing programs. 60 engineering graduate students participated in this study. During the ESAP course, collaboratively designed discipline-specific writing tasks were presented and practiced through multimodal input. The catalysts and the barriers to the learning transfer act were identified by administering the Learning Transfer System Inventory (LTSI). Results indicated that the students could obtain significant levels of academic writing skills and finally transfer their acquired instruction to authentic discipline practices. Furthermore, data analysis demonstrated that transfer of writing outcomes will be increased if more consideration of work-related factors is considered in higher education. All participants reported personal capacity as the main impediment induced by the work-related construct. Students’ positive attitudes toward three ability factors and all motivational factors suggested that an auspicious foundation for future educational planning exists if disciplinary and institutional considerations are embraced.

In human-made materials, aerogels have the least thermal conduction coefficient. The least thermal conduction, which aerogels can have, is equivalent to air conduction, about 0.021W/mK. In some applications, lowest conductions is to be needed. In this study, novolac aerogles are used as spacer, for designing and making multilayer super insulators with aluminum foil reflective layers. The performance of these insulators, are extremely depends on density, porosity and the size of pores in aerogel and number of layers in the overall thickness of insulator. In this study, for decreasing effective thermal conduction of multilayer insulations, tow parameters of density of aerogel and ratio of number of layers to thickness of insulator (layer density), are examined in 25 ˚C to 200 ˚C boundary conditions. First, by assessment of aerogel novolac density effect on thermal conduction, aerogel with density of 0.076 g/cm3 was chosen as the best spacer. In the next part, ratio of 25 layer per centimeter of thickness was chosen as the best layer density. Finally, by making multilayer super insulators, based on this results, an insulator with 5×10-4W/mK effective thermal conductivity was obtaind without evacuation of spacer.

  Prediction of climatic variables on a local scale by General Circulation Models of the atmosphere is impossible because the models have large-scale network of resolution. Therefore, downscaling methods are used to solve this problem. Since the climate change phenomenon can affect different systems such as, water resources, agriculture, environment, industry and economy as well, Selection of the most suitable downscaling method is very important. This study aims to evaluate performance of Change-Factor (CF) and LARS-WG downscaling methods in prediction of future climate variability of the Azam River Watershed, located in Yazd Province, Iran, for the period of 2010-2039. For this purpose, the CGCM3-AR4 model under the A2 emission scenario and also two methods of downscaling including statistical (LARS-WG) and proportional (CF) approaches were applied. The results showed increasing of temperature by both downscaling methods in the Azam River watershed in the future. Average temperature difference obtained from the two methods is about 3 to 4 percent. On the other hand, based on the climate condition, the amount of rainfall varied in the whole watershed, in a way that the future maximum precipitation difference calculated by two downscaling methods is about 30 percent.

Research Subject: In this paper, the adsorbents used to remove lead ion using adsorption operation have been reviewed.
Research Approach: The types of adsorbents used to remove lead ions, the modifications of adsorbents, adsorption conditions, isotherms and adsorption capacity of adsorbents have been investigated and compared based on the literature survey.
Main Results: Modification by impregnation of functional groups has a significant role in increasing the adsorption capacity. The pH of the solution plays an important role in the adsorption of lead ions and generally the adsorption capacity increases by increasing the pH of the solution. Langmuir's isotherm model has been more consistent with the equilibrium data. Among the reviewed adsorbents, carbon-based adsorbents such as activated carbon and graphen-oxide, modified by chemicals such as ammonium persulfate or polyamines, show higher adsorption. Also, biomasses due to their abundance and low prices have the potential to be used as lead ion adsorbents.

Background: Human papillomavirus (HPV) is one of the most common causes of sexually transmitted disease (STD) in humans. HPV is associated with gynecologic malignancy and cervical cancer among women worldwide. In the current study we sought to determine the prevalence rate of HPV in Iranian women identified with cervical infections.
Materials and Methods:  Prevalence rate of HPV in Iran was investigated from 2000-2016 using several databases including Medline, Web of Science, Embase, Google Scholar, Iranmedex, and Scientific Information Database. Statistical analysis was performed by Comprehensive Meta-Analysis (V2.2, Biostat) software. Random effects models were used by taking into account the possibility of the heterogeneity between the studies, which was tested through the Cochran’s Q-statistic.
Results: The meta-analyses showed that the prevalence rate of HPV infections was 38.6 % (95% CI, 27.9-50.5) among Iranian women with cervical infections. The further stratified analyses indicated that the prevalence rate of HPV was higher in the studies conducted during the 2000-2008 years.
Conclusion: The results of the present study underscore the need for further enforcement of STD control strategies in Iran. Establishing advanced diagnostic facilities for HPV, vaccination of high risk groups, and continuous monitoring of HPV are recommended for HPV prevention and control.

In the domain of the Ezafe construction in Persian, sometimes, there is found a DP known as the possessor. This article aims at establishing the process of possessor raising in Persian within the Minimalist program (Chomsky 1995).  To do this, it is argued that in the domain of the Ezafe construction in Persian, a syntactic constituent may be merged in the spec of the nP where it receives its possessor theta role. This constituent, then, raises to the spec of the dominating DP to get its [+definite] feature checked along the lines of Ritter (1991, 1992). This is a novel proposal for Persian and is important in that it takes the possessor DP as bearing a theta role and leads to the classification of Persian as a language with definite like possessive construction.

The representation of kinship relationships in Persian proverbs has been studied in this research. Method of the research is descriptive-analytic and during that some proverbs were extracted from the Great Dictionary of Persian Proverbs and those proverbs which were from non-Persian languages and dialects were deleted. Finally, 3332 Persian proverbs relevant to kinship relationships have been received. The proverbs were firstly classified based on kinship mentioned on them and abundance of the proverbs of each kinship received. Then based on Murdock Theory, kinfolks were classified and compared according to the kind of kinship, marriage kinship, blood or half-blood kinship, the degree of kinship, first, second and third degree and far kinship. Gender, generation and decent of kinfolk, gender of self and kind of family were also considered and were set as the basis for comparison of the mentioned kinship in the proverbs. Those proverbs related to the woman (as the wife) are more than the other kinfolks, while those proverbs related to marriage kinship are more than blood and half-blood kinship. After the woman, father has the second place and the child has the third one. Female kinfolks were mentioned more than male kinfolks in the proverbs, but at the same time, the abundance of those proverbs relevant to men kinfolks are more than women kinfolks.

The rise of bacterial infections has become a serious problem in human societies. As a result, the development of nanocomposite materials based on biocompatible and non-hazardous materials, besides having antimicrobial and biocompatibility or non-cytotoxicity, associated with unique structural properties, possesses a great importance. Research approach: In this study, bacterial cellulose (BC)/polypyrrole (PPy) and zinc nanoparticles (ZnO), which simultaneously have antimicrobial properties and cell proliferation, were introduced as a new generation of nanocomposite scaffolds produced by freeze-drying. To begin with, ZnO with different weight percentages of 1%, 3% and 5% was added to BC and then PPy in the amount of 2 mmol was embedded in the structure by in situ polymerization. FESEM images proved that the nanofibrous and porous structure of BC was also preserved in the presence of PPy and ZnO. However, after adding PPy and ZnO, they formed a dense structure and microstructure of grape clusters. By adding 2 mmol PPy into BC and upon in situ synthesizing, the tensile strength and Young modulus of BC were significantly reduced to 71 MPa and 2.5 GPa, respectively. On the other hand, with the addition of ZnO nanoparticles, the mechanical properties significantly increased (both of Young modulus and tensile strength compared to BC/PPy samples) due to the compaction of the nanocomposite aerogel’s structure and the formation of the interface of ZnO nanoparticles with both polymers of BC and PPy. The observation of the inhibition zone in the culture medium containing two gram-positive and negative bacteria, well proved the antibacterial ability of ternary nanocomposite scaffolds. The results of MT9 related to L929 on aerogels showed that by adding 3% of ZnO nanoparticles, adhesion and cell proliferation increased significantly during different days of 1 day, 5 days and 7 days of culture.

Aim: Oral hygiene must start at a young age. Childhood is the perfect time to start the conversion of knowledge into creative thinking and subsequent health care activity. This study aimed to measure the constructs of the Health Belief Model (HBM) in relation to the oral health practice of female students in Tehran.
Methods: A cross-sectional descriptive study was conducted on 416 grade five female students of elementary schools in the school year of 2016-2017 in Tehran, Iran. Data were collected using an author-designed questionnaire based on the constructs of the HBM. The validity of the questionnaire was confirmed using face validity while its reliability was approved using Cronbach’s alpha statistics. Data were analyzed using Pearson's correlation and regression analysis at 0.05 level of significance.
Findings: According to the findings, the mean age of the participants was 10.88±0.628 years. Pearson's correlation showed that four the HBM constructs of Self-efficacy, Cues to action, Perceived benefits, Perceived barriers were significant predictors for oral health practices (P < 0.05). In addition, the variables of knowledge and socio– economic conditions (mother's educational level, father's educational level, mother's job, father's job and family income) had significant relationship with performance (P < 0.05).
Conclusion: Our study shows that for improving the beliefs related with oral health behaviors, designing educational programs with emphasis on increasing self-efficacy and perceived benefits, and overcoming the barriers to promote oral health behaviors is essential.
