For any operator on integer-valued functions, we say that #P is closed under in context PF#P if, for every f 2 #P, f] belongs to PF #P. For several operators , it is shown that the closure properties of #P under in the above sense is closely related to the relationships between P #PP1] and higher classes such as PH PP and PP PP .

In recent years, the decay η → 3π has received considerable attention from experimental and theoretical side. It is of particular theoretical interest because it allows for the determination of (mu −md). In addition, for many years now theory has had difficulties to understand the slope of the neutral channel Dalitz plot distribution, which in contrast is very well measured. I discuss here the ...

We consider whether or not protein chains in the HP model have unique or few optimal foldings. We solve the conjecture proposed by Aichholzer et al. that the open chain L2k−1 = (HP )(PH) for k ≥ 3 has exactly two optimal foldings on the square lattice. We show that some closed and open chains have unique optimal foldings on the hexagonal and triangular lattices, respectively.

مطالعۀ چرخۀ حیات محصول روشی مناسب برای ارزیابی اثرات زیست‌محیطی تولید آن محصول است. در این تحقیق، اثرات زیست‌محیطی (شامل گرمایش جهانی، اسیدیته، هوپرورش خشکی و تخلیۀ منابع فسیلی) محصول گندم در شهرستان مرودشت استان فارس با روش ارزیابی چرخۀ حیات محاسبه شد و سپس سهم این اثرات زیست‌محیطی در سرانۀ اثرات زیست‌محیطی کشور تعیین شد. اطلاعات لازم به روش مصاحبه، پرسش‌نامه و حضور در سازمان جهاد کشاورزی شهرس...

هدف از تحقیق حاضر ارزیابی چرخۀ حیات انرژی و اقتصادی تولید بیودیزل از روغن تفالۀ زیتون با استفاده از امواج فراصوت است. بدین منظور تولید بیودیزل در قالب چرخۀ حیات متشکل از مراحل تولید کشاورزی زیتون، حمل‌و‌نقل، روغن‌کشی زیتون، روغن‌کشی تفالۀ زیتون، و تولید بیودیزل بررسی شد. نتایج نشان داد که میزان انرژی ورودی در طی چرخۀ حیات تولید بیودیزل براساس مدل تخصیص جرم و تخصیص اقتصادی به ‌ترتیب 91/2601 و 04...
