Low dielectric constant (low-k) is achieved often at the cost of degraded mechanical properties, making it difficult to integrate the dielectric in the back end of line (BEOL) and to package low-k chips. Development of low-k technology becomes costly and time-consuming. Therefore, more frequently than before, people resort to modeling to understand mechanical issues and avoid failures. In this ...

the aim of the present study was to examine the effect of aerobic training and green tea supplementation on serum leptin and insulin resistance in overweight and obese men. for this purpose, 43 overweight and obese men were selected voluntarily and were included in four groups: control (body mass index 31.4+3.7, vo2max 39.3+3.8 ml/kg.min), green tea supplement (body mass index, 30.3±2.8 k/m2, v...

The wind loads considerably influence lightweight spatial structures. An example of spatial structures is scallop domes that contain various configurations and forms and the wind impact on a scallop dome is more complex due to its additional curvature. In our work, the wind pressure coefficient (Cp ) on the scallop dome surface is studied numerically and experimentally. Firstly, the programming...

Understanding the kinetics of gas hydrate formation is essential to model and predict the hydrate formation (or dissociation) process. In the present paper, we investigated the formation of pure propane gas hydrate as a former gas. In this regard, several experiments were conducted to measure the rate of hydrate formation under various pressures (410 to 510 kPa) and temperatures (274 K to 277 K...

to investigate the interaction and adsorption of drug and carbon nanotube on human serum albumin, three anti-cancer drugs ([pd(phen)(r-gly)]no3, r = methyl, propyl and amyl) with different hydrophobic tails and anticancer activities were selected. these drugs have better anti-tumor activity and less side effects than that known cis-platinum drug. human serum albumin is also important for drug d...
