Article history: Received 4 August 2007 Received in revised form 2 May 2008 Accepted 19 May 2008 We investigated tissue fatty acids (FA) profiles, systemic and portal plasma biochemical characteristics, and cecal digesta biogenic amines in piglets fed diets containing flaxseed (FS) and a multi-carbohydrase enzyme supplement (C). Enzyme supplement provided 500 U pectinase, 50 U cellulase, 400 U ...
امروزه صنایع stealth شاخه ای مهم در بحث های نظامی هستند. یکی از راه های مخفی کردن هدف از دید رادار دشمن کاهش rcs آن است. با بکارگیری روش هایی متعدد، مانند مواد جاذب، توانسته اند mrcs هدف را کاهش دهند. اما در یک رادار دوپایه از نوع fsr پدیده ای به نام fs استفاده می شود که با روش های معمول کاهش rcs نمی توان آن را کاهش داد و حذف کرد. یعنی ممکن است یک هدف با وجود mrcs بسیار کم، frcs زیادی داشته باش...
The effects of ground flaxseed (FS) and a multicarbohydrase enzyme (C) supplement on piglet performance, gastrointestinal microbial activity, and nutrient digestibility were investigated in a 28-d trial. The enzyme supplement provided 500 units of pectinase, 50 units of cellulase, 400 units of mannanase, 1,200 units of xylanase, 450 units of glucanase, and 45 units of galactanase per kilogram o...
a 42-d study was conducted to evaluate the influence of full-fat flaxseed (fs) and canola seed (cs) on broiler performance, fatty acid (fa) profile of meat, and the oxidative stability of meat during frozen storage. a total of 324 one-day old broiler chicks were randomly attributed to 6 experimental groups and fed iso-energetic and isonitrogenous diets as follows, c: control (soybean-corn); cs1...
Using data collected by the Fermilab experiment FOCUS, we measure the lifetime of the charmed baryon Ξc using the decay channels Ξ o c → Ξ π and Ξc → Ω K. From a combined sample of 110 ± 17 events we find τ(Ξc) = 118 +14 − 12 ± 5 fs, where the first and second errors are statistical and systematic, respectively.
Air quality prediction is highly important in view of the health impacts caused by exposure to air pollutants in urban air. This work has presented a model based on support vector machine (SVM) technique to predict daily average carbon monoxide (CO) concentrations in the atmosphere of Tehran. Two types of SVM regression models, i.e. -SVM and -SVM techniques, were used to predict average daily C...

The sixth harmonic (6ω, 133 nm) of a Ti:sapphire laser is generated using cascaded four-wave mixing in filamentation propagation of the fundamental (ω) and the second harmonic (2ω) pulses through Ne gas. The method provides the 6ω pulse energy higher than 5 nJ/pulse at 1 kHz and a pulse duration shorter than 17 fs without dispersion compensation.
We report on the generation of self-similar pulses from an self-starting saturable absorber mirror (SAM) based environmentally stable fiber laser comprising only polarization maintaining (PM) fibers. Pulse energies of 1 nJ at a repetition rate of 17 MHz were obtained, which could be externally compressed to an autocorrelation width of 280 fs.
