this study was conducted to investigate the effect of mentha piperita (pp) and melissa officinalis (mp)powder on performance, apparent digestibility of fat and protein and blood parametersof broiler chicks subjected to heat stress. 200-day-old male ross broiler chicks were assigned to a completely randomized design with five dietary treatments and four replicates. the experimental treatments we...
پلی پروپیلن (pp) به علت فرآیند پذیری خوب، مقاومت بالا در برابر جذب رطوبت، مقاومت شیمیایی خوب، قیمت مناسب و توان عملیاتی بالا و در دسترس بودن همواره در صنعت مورد توجه بوده و یکی از پرمصرف ترین و پرکاربردترین پلیمرهای موجود است. pp در کاربرد های مهندسی دارای محدودیت در خواص مکانیکی می باشد. افزودن الیاف شیشه (gf) به pp منجر به بهبود برخی خواص مکانیکی شده است ولی باعث کاهش شدید فرآیند پذیری می شو...
In a recent paper, Bruinier and Ono prove that the coefficients of certain weight −1/2 harmonic Maass forms are traces of singular moduli for weak Maass forms. In particular, for the partition function p(n), they prove that p(n) = 1 24n− 1 · ∑ Pp(αQ), where Pp is a weak Maass form and αQ ranges over a finite set of discriminant −24n + 1 CM points. Moreover, they show that 6 · (24n − 1) · Pp(αQ)...
High-melt-strength (HMS) polypropylene (PP) has enabled easy supercritical-CO2 (scCO2) foaming of PP. However, producing microcellular PP foams via simple scCO2 extrusion still remains challenging, whereas macrocellular with high expansion ratios (ER) generally exhibit poor mechanical strengths. In this study, to simultaneously enhance both ER and compressive strengths foams, a type low-cost Ja...
in this study, pp films were modified with an organic pro-degradant in different concentrations (1, 2 and 3wt.%), exposed in the first step of degradation to natural ageing for 100 days followed by biodegradation insimulated soil in the respirometric test for 100 days. at the end of the combined degradation process the pp sampleswere characterized according to their morphological and physical p...

Büchi’s theorem, in establishing the equivalence between languages definable in S1S over pP,ăq and the ω-regular languages also demonstrated that S1S over pP,ăq is no more expressive than its existential fragment. It is also easy to see that S1S over pP,ăq is equi-expressive with S1S over pP, sq. However, it is not immediately obvious whether it is possible to adapt Büchi’s argument to establis...
An occupation restricted multiple active space (ORMAS) study of clusters that represent the silicon(100) surface (up to nine surface dimers) is discussed. The accuracy of three different active orbital ORMAS partition schemes for Si(100) surface clusters are compared. In addition to ORMAS-SCF calculations, generalized valence bond-perfect pairing (GVB-PP) properties are generated for comparison...
