the amygdala is a forebrain region, which is known as a modulator of pain sensation. the amygdala, particularly the central nucleus, has high concentrations of enkephalins relative to dynorphins and has high concentrations of opioid receptors. we here studied the role of central nuclei of amygdala in morphine antinociception. methods: in this study, we used 130 male wistar rats (200- 250g). bil...
background: pneumoperitoneum results in respiratory and hemodynamic changes. it is unknown whether hemodynamic changes that last to the recovery room could change recovery criteria. to determine the effect of decrease in intra-abdominal pressure on discharge criteria after laparascopic cholecystectomy. methods: patients with age 25-65 who were candidated for elective laparascopy cholecystectomy...
While the efficiency of exploiting inter-frame motion compensation is well established for lower bit rates, far less attention has been given to this issue for digital cinema resolutions. This paper addresses the specific coding efficiency differences between inter and intra frame coding for very high quality, high-resolution image sequences and at a wide variety of bit rate ranges. The informa...
In this paper we present a new coding and packetization approach for intraframe coded video transmission, based on space-frequency dispersion. Subband-decomposed video data is packetized so that data appearing in any one packet is highly dispersed in both space and frequency. Each packet is a description of the frame at various points in space and frequency. Any errors arising from packet loss ...
اَبَر بتن خودمتراکم (high performance high strength self compacting concrete, hphsscc)، بتن نسبتا جدیدی است بدون نیاز به ویبره و با مقاومتی حدود 800 kg/cm2 که در صورت استفاده از آن در سیستم های پس تنیده، صرفه جوئی های بیشتری نسبت به چنین بتن هائی با نیاز به ویبره را بدست خواهد داد.
امروزه ، استراتژی ها و روشهای مختلفی توسط مترجمان در زمینه ترجمه متون به کار گرفته می شود. یکی از این روشهای رایج، استفاده از شیفت ها است. مطالعه ی پیش رو کاربرد استراتژی شیفت ها در ترجمه بروشورهای تبلیغاتی مربوط به محصولات مراقبت شخصی از زبان انگلیسی به فارسی را بر اساس مدل کتفورد (1965) مورد بررسی قرار داده است. هدف این مطالعه بررسی میزان استفاده از این استراتژی از طریق مقایسه متون زبان مبدا ...
PROBLEM Inflammation and infection play a major role in preterm birth. The purpose of this study was to (i) determine the prevalence and clinical significance of sterile intra-amniotic inflammation and (ii) examine the relationship between amniotic fluid (AF) concentrations of high mobility group box-1 (HMGB1) and the interval from amniocentesis to delivery in patients with sterile intra-amniot...
