BACKGROUND The present study was undertaken to gain knowledge on the role of bile components and lecithin on development of aberrations in digestive functions which seemingly have increased in Atlantic salmon in parallel with the increased use of plant ingredients in fish feed. Post smolt Atlantic salmon were fed for 77 days one of three basal diets: a high fish meal diet (HFM), a low fishmeal ...
در این مقاله یک آنتن شکافی مایکرواستریپی چاپی جدید با خاصیت پلاریزاسیون دایروی و تغذیه شده با خط CPW طراحی، تحلیل و شبیه سازی شده است. ساختار آنتن شکافی پیشنهادی از یک پچ پله ای شکل اصلاح شده و صفحه زمین مربعی که درون آن یک شکاف پله-ای واقع شده ترکیب بندی شده است. با استفاده از پچ پله ای و صفحه زمین مربعی اصلاح شده، رزونانس های اضافی دیگری تحریک شده و پهنای باند امپدانس وسیعی مخصوصا در باند بال...
BACKGROUND Several studies on Caucasian volunteers have proven that milk is an effective recovery drink for athletes. Such benefit, however, cannot be directly applied to the lactose-intolerant Asian population. This study investigated the effects of ingesting water (WT), sports drink (SPD) and lactose-free milk (LFM) on cycling capacity. METHODS Ten healthy young men completed 3 randomized e...
An indoor TOA-based ranging system which uses an audible spread spectrum signal is presented. The indoor acoustic environment is modeled with a dense multipath propagation channel whose characteristics are very different from those of outdoor environments. The complexity and site-specific nature of indoor acoustic propagation, when using traditional correlation techniques, often lead to the cre...
In order to verify the chaff jamming performance, according to the time-frequency distribution and statistical characteristics of chaff echo, this paper presents a modeling and simulation method of chaff echo based on its mechanism of generation, Also it presents a simulation study of chaff echo signal based on LFM signals. The simulation results indicate that the generated chaff echo of this m...
A new LFM-signal detector formulated by the integration of the 4th-power modulus of the fractional Fourier transform is proposed. It has similar performance to the modulus square detector of Radon-ambiguity transform because of the equivalence relationship between them. But the new detector has much lower computational complexity in the case that the number of the searching angles is far less t...
Breakfast beverages with different nutrient compositions may affect postprandial glycemic control differently. We assessed the effects of consuming (1) common breakfast beverages (water, sugar-sweetened coffee, reduced-energy orange juice (OJ), and low-fat milk (LFM)); and (2) fat-free, low-fat, and whole milk with breakfast on postprandial plasma glucose and insulin responses in adults who wer...
To maintain upright posture and prevent falling, balance control involves the complex interaction between nervous, muscular and sensory systems, such as sensory reweighting. When balance is impaired, compliant foam mats are used in training methods to improve balance control. However, the effect of the compliance of these foam mats on sensory reweighting remains unclear. In this study, eleven h...
حساسیت پهپاد (UAV) به اغتشاشات جوی باعث انحراف آن از مسیر مستقیم و ایجاد خطای حرکت در تصاویر رادار روزنه ترکیبی پهپاد (UAV SAR) میشود. در این مقاله جبران خطای حرکت یک UAV SAR که در مود تصویربرداری نواری در ارتفاع پایین کار میکند و از سیگنال LFM پلهای برای افزایش تفکیکپذیری برد بهره میبرد، بررسی میگردد و دو رویکرد جبران حرکت همراه با تشکیل تصویر پیشنهاد میشود. برای جبران حرکت، روشهای قبل...
Most studies showing that children consuming breakfast have better nutrient intakes, diet quality, and lower weight than breakfast skippers have the incorrect premise that breakfast meals are homogeneous. The purpose of this study was to classify breakfast meals into patterns and determine the association of the breakfast patterns with daily and breakfast nutrient intakes, diet quality, and wei...
