For the purpose of determining neurophysiological mechanism of math anxiety, we conducted an EEG measurement for 22 sixth grade elementary students including 11 students with high math anxiety (HMA group), and 11 students with low math anxiety (LMA group). We found that in HMA group, delta wave was significantly generated from the right frontal lobe, and in LMA group, four paths are clearly con...

تامین مقاومت لغزندگی کافی در زمینه راهسازی یکی از اقدامات مهم و اجتنابناپذیر است. پژوهش حاضر در پی آناست که امکان فنی استفاده از درصدهای مختلف آسفالتهای بازیافتی را، هم در بافت ریز و هم در بافت درشتروسازی راهها، بهمنظور کاهش لغزندگی مورد بررسی قرار دهد. برای اندازهگیری لغزندگی، روش آونگ انگلیسی بهکار گرفته شده است. در این تحقیق پانزده نمونه آسفالت درشتدانه و پانزده نمونه آسفال...

Abstract A robust understanding of the sub-seasonal cold season (November–March) precipitation variability over High Mountains Asia (HMA) is lacking. Here, we identify dynamic and thermodynamic pathways through which natural modes climate establish their teleconnections HMA. First, evaporative sources that contribute to HMA surrounding areas. The predominant moisture contribution comes from mid...

Abstract Rain‐on‐snow (ROS) over snow‐dominated regions such as High Mountain Asia (HMA) modulates snowmelt and runoff is key contributor in influencing water availability hazards (e.g., floods landslides). We studied the trends ROS HMA past two decades from 2001 to 2018 using land surface model Noah‐MP driven by an ensemble precipitation data set. Our results show that changes phase rainfall a...

روسازی راه­ها بخش قابل ملاحظه­ای از ثروت ملی هر کشوری را تشکیل داده و همه­ساله سرمایه هنگفتی صرف نگهداری، تعمیر و ترمیم آن می­گردد. یکی از شایع­ترین خرابی روسازی­های انعطاف­پذیر، که عمدتاً ناشی از ضعف مقاومت برشی آسفالت می­باشد، شیارشدگی است. راهکار اصولی جلوگیری از ایجاد چنین پدیده مخربی، استفاده از مخلوط­هایی است که مقدار پارامترهای مؤثر در مقاومت برشی آسفالت در آن­ها کنترل شده باشد. پارامترها...

Rubblization is considered one of the sustainable surface preparation techniques before placing a hot mix asphalt (HMA) overlay that involves breaking the concrete pavement into pieces. The design of the structural overlay thickness for rubblized projects is difficult as the resulting structure is neither a true rigid pavement nor a true flexible pavement. The most important aspect of the desig...

The development and validation of a tool that can estimate the level of compaction of a Hot Mix Asphalt (HMA) pavement during its construction is addressed in this paper. Densification of asphalt pavements during their construction is usually accomplished through the use of vibratory compactors. During compaction, the compactor and the asphalt mat form a coupled system whose dynamics are influe...

Heteroduplex mobility assay (HMA) is a fast and inexpensive method for determining relatedness between DNA sequences. Rapidly evolving viruses such as HIV-1 develop marked sequence differences in their genomes over the course of the epidemic and infection in a single individual. HMA can be used to monitor both processes. Here, we systematically evaluated the influence of single base mismatches ...

INTRODUCTION Section 5(ii) of The Hindu Marriage Act, 1955 (HMA) states that under certain circumstances, mental illness is accepted as a ground for the annulment of marriage, while Section 13(1) (iii) states that mental illness is a ground for divorce. There is little data on how this provision is used and applied in matrimonial petitions. This paper assesses judicial practices in divorce case...
