BURFEL BIAS AND MCNP BENCHMARKING BURFEL CALCULATIONS OF NRU LOOP FUEL

Benchmarking Calculations of Excitonic Couplings between Bacteriochlorophylls.

Excitonic couplings between (bacterio)chlorophyll molecules are necessary for simulating energy transport in photosynthetic complexes. Many techniques for calculating the couplings are in use, from the simple (but inaccurate) point-dipole approximation to fully quantum-chemical methods. We compared several approximations to determine their range of applicability, noting that the propagation of ...

بوزدایی از ‏‎fuel oil deodorization of fuel oil‎‏

مطالعات و بررسی های انجام گرفته نشان می دهد ترکیبات بودار موجود در ‏‎fuel oil‎‏ عمدتا ترکیبات سولفوردار سخت مثل تیوفن، دی متیل بنزوتیوفن و ... بوده و روشهای بوزدایی همچون استخراج با حلالهای اسیدی و بازی ، رقیق کاری با گازولین ، ماسکینگ با بوتیل استات نتایج چندان مطلوبی در بوزدایی از آن نشان نمی دهند.همچنین روش جذب سطحی برای بوزدایی ‏‎fuel oil‎‏ تنها با استفاده از جاذب هایی همچون بنتونیت و توفیت...

Loop Calculations and OZI Rule

The role of two step mechanisms in the OZI rule violation in NN̄ annihilation at low energies is reviewed. The full calculation of two-meson doorway mechanisms shows that the off-mass-shell contributions are important. Moreover, for the φπ0 and φρ annihilation channels three-meson doorway contributions are non-negligible and improve agreement with the data. A significant enhancement of φ product...

an investigation into iranian teachers consistency and bias in evaluation of students writings

while performance-based language assessment has led to an increased authenticity and content validity in the practice of writing assessment, the reliability of ratings has become a major issue. research findings have shown different reactions by native english speaker (nes) and non-native english speaker (nns) teachers to students’ writings. the focus of this study is on investigating whether i...
