the objective of this study was the evaluation of ph, color parameters [lightness (l*), redness (a*), yellowness (b*), chroma (c*), hue (h*), a*/b* ratio, and color differences (δe)], mb, metmb, oxymb, deomb and whc in minced meat. three types of meat ( beef, camel and ostrich) and four mincing processes (three using a grinder with 7.5, 4 and 3 mm diameter holes in the plate, and a fourth in wh...
We study the two-body and three-body charmful baryonic B decays: B 0 → Λc p̄ and B → Λc p̄ π(ρ). The factorizable W -exchange contribution to B 0 → Λc p̄ is negligible. Applying the bag model to evaluate the baryon-to-baryon weak transition matrix element, we find B(B → Λc p̄) <∼ 2.5 × 10−5|gB0pΣ+b /8| 2 with gB0pΣ+ b being a strong coupling for the decay Σb → B 0 p and hence the predicted branchin...
The measurement of the lifetime ratio for neutral and charged B mesons was performed using the statistics collected by DØ experiment in Run II and corresponding to approximately 250 pb−1. B hadrons were reconstructed in semileptonic decays B → μ+νD∗(2010)−X, which are dominated by B decays and B → μνDX, which are dominated by B decays. The lifetime ratio was obtained from the variation of the r...
An examination of leptons in Υ(4S) events tagged by reconstructed B decays yields semileptonic branching fractions of b− = (10.1 ± 1.8 ± 1.4)% for charged and b0 = (10.9 ± 0.7 ± 1.1)% for neutral B mesons. This is the first measurement for charged B. Assuming equality of the charged and neutral semileptonic widths, the ratio b−/b0 = 0.93 ± 0.18 ± 0.12 is equivalent to the ratio of lifetimes.
تا کنون مطالعات بسیاری در باره پیش بینی پره اکلامپسی انجام شده و متدهای بسیاری برای screen بیماری وجود دارد که این متدها شامل متدهای قدیمی و رایج مثل roll over test سابقه خانوادگی و پاریتی میباشد. متدهای آزمایشگاهی جدیدی اخیرا مورد بررسی قرار گرفته است که از آن جمله بررسی میزان فیبرونکسین پلاسما و بررسی کلسیم ادراری است که یا از طریق نسبت ca/cr در یک نمونه ادراری و یا بررسی کلسیم ادرار 24 ساعته...
The flow velocity wave forms generated by Doppler ultrasound examination of the umbilical artery were correlated with fetoplacental blood flow and numerically expressed as a ratio between the systolic (A) and the end-diastolic point (B). The technique is non-invasive and simple to perform. A cohort analytical study was done to see whether useful information could be obtained from the A/B ratio ...
The golden ratio has fascinated people of diverse interests for at least 2,400 years (see e.g. [24]). In mathematics (and the arts) two quantities a and b are in the golden ratio if the ratio of the sum of the quantities a+b to the larger quantity a is equal to the ratio of the larger quantity a to the smaller quantity b . This amounts to setting (a+b)/a = a/b =: φ and solving φ2−φ−1 = 0 which ...
Introduction & Aim: The aim the present study is to examine the effects of Boswellia serrata Triana & Planch on (immune response) performance and carcass characteristic in broiler chicks. Experimental: In this study, 360 one day old chicks (Ross 308) were allocated to six treatments with four replicates in a completely randomized design for a six week period. Treatments consisted of ...
Abstract This study investigated the optimal water/binder (w/b) and aggregate/binder (a/b) ratios in producing a concrete paving block. The w/b a/b block were optimised using response surface methodology (RSM), considering performances of ultrasonic pulse velocity (UPV), flexural, compressive strengths. Regression modelling was conducted to represent relationships between UPV strength flexural ...
Boron (B) is an essential micronutrient for vascular plants. The function of B has been demonstrated to cross-link monomeric rhamnogalacturonan II (mRG-II) to form dimeric RG-II-borate (dRG-II-B), and thus to stabilize plant cell walls. The dRG-II-B to total RG-II ratio in the cell walls of pumpkin hydroponically grown under various low-B conditions was analyzed to evaluate its applicability to...
