COVID-19 pandemic, combined with the serious economic impact and social disruption, have made planning fundraising support IBC impossible. With these facts mind, IABMS concluded that XX must We thank Sociedade Botânica do Brasil for understanding this difficult decision. know large botanical comm...

جداسازی ایزومرهای آلکانها توسط زئولیتها از اهمیت ویژه ای برخوردار است. در این تحقیق روش مونت کارلو برای شبیه سازی مولکولی جذب ایزومرهای پنتان بصورت خالص و مخلوط دوجزئی روی زئولیت mfi مورد استفاده قرار گرفته است. اثر مقدار آلومینیم در زئولیت mfi (با نسبت سیلیسیم به آلومینیم 18، 31 و ∞ ) روی جذب ایزومرهای پنتان مورد بررسی قرار گرفت. نتایج بدست آمده نشان داد که ساختارهای با نسبت سیلیسیم به آلومینی...

Health spending growth in the United States is projected to average 5.8 percent for 2014-24, reflecting the Affordable Care Act's coverage expansions, faster economic growth, and population aging. Recent historically low growth rates in the use of medical goods and services, as well as medical prices, are expected to gradually increase. However, in part because of the impact of continued cost-s...

Experimentally determined T ε and CTOA resistance curves were used to simulate numerically, stable crack growth and the ensuing crack linkup in 0.8 mm thick 2024-T3 aluminum tension specimen with multiple site damage (MSD) subjected to monotonically/cyclically increasing loading. The T ε integral correctly predicted the crack growth and linkup history as well as the onset of rapid fracture in M...
