the objective of the present study was to estimate genetic parameters and genetic trends of growth traits , fleece weight and reproductive traits. data collected from 1993 to 2007 by the kermani breeding station were analyzed .traits were included birth weight (bw, n=2614), 3 months weight (3mw,n=2312), 6 months weight (6mw, n=1890), 9 months weight (9mw,n=1380) and 12 months weight (12mw,n=105...
OBJECTIVES To evaluate the effect of different pathways for developing a life story book (LSB) for people with dementia. METHOD Preliminary randomised control trial; 23 people with dementia in care homes (mean age 86) randomly assigned to receive either 12 individual life review sessions and co-creating a LSB or a personal LSB created by their relatives as a 'gift' RESULTS No difference in ...
We present results of surface photometry for eleven edge-on galaxies observed with the 6-m telescope at the Special Astrophysical Observatory of the Russian Academy of Sciences. The photometric scale length, the scale height, and the central surface brightness of the stellar disks for the galaxies were found using photometric cuts made parallel to the major and the minor axes for each galaxy. W...
Lumbar sympathetic block (LSB) is an effective method for relief of sympathetically mediated pain in the lower extremities. To prolong the sympathetic blockade, sympathetic destruction with alcohol or radiofrequency has been used. The pre-ganglionic sympathetic nerves are cholinergic, and botulinum toxin (BTX) has been found to inhibit the release of acetylcholine at the cholinergic nerve termi...
In this paper, a few novel data hiding techniques are proposed. These techniques are improvements over the classical LSB data hiding technique and the Fibonacci LSB data-hiding technique proposed by Battisti et al. [1]. The classical LSB technique is the simplest, but using this technique it is possible to embed only in first few bit-planes, since image quality becomes drastically distorted whe...
An 8 bit segmented current steering DAC is presented for the compensation of mismatch of sensors with current output arranged in a large arrays. The DAC is implemented in a 1.8 V supply voltage 180 nm standard CMOS technology. Post layout simulations reveal that the design target concerning a sampling frequency of 2.6 MHz is exceeded, worst-case settling time equals 60.6 ns. The output current ...
Compared with Shamir’s original secret image sharing (SIS), the Chinese-remainder-theorem-based SIS (CRTSIS) generally has advantages of a lower computation complexity, lossless recovery and no auxiliary encryption. However, general CRTSIS is neither perfect nor ideal, resulting in narrower range share pixels than that pixels. In this paper, we propose practical based on Asmuth Bloom’s threshol...
در این مقاله، ابتدا مروری جامع بر نهاننگاری تصویر مبتنی بر مخفیسازی در کمارزشترین بیت و دستهبندی پیکسل انجام و سپس، روشی برای نهاننگاری اطلاعات در تصویر ارائه شده است. این روش مبتنی بر مخفیسازی پیام در کمارزشترین بیت (LSB) تصویر است. هدف ما در این مقاله، بهکمینهرساندن تغییرات در تصویر پوشانه است. در روش پیشنهادی، ابتدا پیکسلهای تصویر برای مخفیسازی پیام انتخاب و سپس مکمل پیام در ...
Salviae miltiorrhiza, a traditional Chinese medical herb known as "Danshen," has been widely used in clinics to improve blood circulation, relieve blood stasis, and treat coronary heart disease. Depside salts from S. miltiorrhiza are a novel drug in which magnesium lithospermate B and its analogs are the active components. The pharmacokinetics, tissue distribution, metabolism, and excretion of ...
سابقه و هدف: یکی از عوارض میکانیکال بعد از انفارکتوس حاد میوکارد (acute myocardial infraction: ami) پارگی سپتوم بطنی (ventricular septal defect: vsd) است که تشخیص آن با اکوکاردیوگرافی رنگی تایید می شود. هدف از این گزارش بررسی تظاهرات بالینی و نحوه برخورد تشخیصی و رابطه vsd بعد از ami با ترومبولیتیک تراپی و نقش مهم اکوکاردیوگرافی رنگی در افراد مبتلا به ami و vsd بعد از آن می باشد. گزارش مورد: بی...
