Plasma urea nitrogen can be used as an indicator of N use and excretion by an animal. The objective of this research was to assess the effect of residual feed intake (RFI) on plasma concentration of urea N (PUN) in 188 bulls, heifers, and steers (mean body weight = 652 lb, SD = 82 lb) ranging from 100% Angus to 100% Brahman. Calves were assigned to pens in a GrowSafe feeding facility by sire gr...
یکی از فرآیندهایی که جهت حذف آسفالتین از باقیمانده های سنگین نفتی بکار می رود ، فرآیند استخراج با حلال های مایع است . در این تحقیق ضمن اشاره به فرآیندهای مختلف بهبود کیفیت ، استخراج آسفالتین از باقیمانده های برج تقطیر در خلاء پالایشگاههای اراک و تهران با حلالهای مایع از جمله پنتان ، هپتان و حلال l.s.r.g . مورد ارزیابی قرار گرفته است. بدین منظور حلالهای مایع فوق الذکر در فرآیند استخراج آسفالتین ...
Observers misperceive the orientation of a vertical rod when it is viewed in the context of a tilted frame (the rod and frame illusion, or RFI). The pitch and roll of the surrounding surfaces have independent influences on this illusion (Nelson and Prinzmetal, 2003). Experiment 1 measured the RFI when the pitch and roll of the floor that supported the observer was varied, and the observer was e...
Increasing levels of Radio Frequency Interference (RFI) are a problem for research in radio astronomy. Various techniques to suppress RFI and extract astronomical signals from data affected by interference are being tried out. However, extracting weak astronomical signals in the spectral region affected by RFI remains a technological challenge. In this paper, we describe the construction of an ...
Radio Frequency Interference (RFI) can adversely impact microwave passive remote sensing measurements, and prohibits passive observations outside protected portions of the radio frequency spectrum. A microwave radiometer including a digital back-end with a simple real-time RFI mitigation technique for reducing pulsed RFI has been developed to address this issue; the process is termed “asynchron...
This review summarizes the results from the INRA (Institut National de la Recherche Agronomique) divergent selection experiment on residual feed intake (RFI) in growing Large White pigs during nine generations of selection. It discusses the remaining challenges and perspectives for the improvement of feed efficiency in growing pigs. The impacts on growing pigs raised under standard conditions a...
در این پژوهش سعی می‌شود مدلی برای شبیه‌سازی چرخه عمر صنعت برق با استفاده از شبیه‌سازی عاملبنیان ارائه شود، مدل، 5 عامل استخراج شد و شبیه‌سازی به کمک نرم‌افزار Anylogic صورت پذیرفت. بهینه‌سازی مدل چهار سناریو نظر خبرگان شد. سناریوی نخست، جذابیت نیروگاه گازی سیکل ترکیبی کاهش یافت بر دو دیگر افزوده نتیجه افزایش تولید آبی است که توجه کمبود منابع کشور به‌صرفه نیست. دوم ورود یک فناوری جدید میزان...
In this paper we address the problem that impulses might occur when a to-be-controlled plant is connected to a suitable controller. In the behavioral literature this issue is dealt when studying the so-called ‘regular feedback interconnection’ (RFI) of the plant and the controller behaviors. We address the question of when a given controlled behavior meeting desired specifications can be obtain...
Radio Frequency Interference (RFI) suppression is an important technique in the ultra-wideband synthetic aperture radar (UWB SAR). In this paper, we mainly analyze the performance of a notch filter for RFI suppression. The theoretical output from notch filter is presented based on RFI signal’s narrowband property. The research conclusion shows that the notch filter has significant effect on sid...
this paper describes the last achievements on the susceptibility to RF interference (RFI) of smart power system on chip. To this purpose, a PWM voltage-mode switching mode power supply (SMPS) has been designed (including the control unit) and a complete analysis about RFI effects on the control circuit operation has been carried out by computer simulations. In particular, it is pointed out that...
