the ability of artificial neural network (ann) for estimating the natural gas demand load for the next day and month of the populated cities has shown to be a real concern. as the most applicable network, the ann with multi-layer back propagation perceptrons is used to approximate functions. throughout the current work, the daily effective temperature is determined, and then the weather data w...
high resolution range profile (hrrp) is being known as one of the most powerful tools for radar target recognition. the main problem with range profile for radar target recognition is its sensitivity to aspect angle. to overcome this problem, consecutive samples of hrrp (or feature vectors extracted from them)were assumed to be identically independently distributed (iid) in small frames of aspe...
مقدمه : ایست قلبی-تنفسی (cpa: cardiopulmonary arrest) در کودکان ناشایع ولی با پروگنوز بدی همراه است. شناخت فاکتور های پیش بینی کننده پیامد بالینی کودکان تحت cpr می تواند در برخورد با این کودکان موثر باشد. هدف از مطالعه حاضر، بررسی فاکتور های دخیل در پروگنوز کودکان تحت احیای قلبی- ریوی (cpr) بستری در picu می باشد. روش کار : این مطالعه به روش مقطعی به مدت 6 ماه در سال 1393، بر روی کودکان بستری...
De novo protein synthesis and transcription are necessary for the expression of long-lasting synaptic potentiation [long-term potentiation (LTP)] in hippocampal area CA1 and for the consolidation of long-term memory. The stability of LTP and its longevity require macromolecular synthesis at later stages, but a specific role for early protein synthesis has not been identified. Using electrophysi...
Sleep deprivation disrupts hippocampal function and plasticity. In particular, long-term memory consolidation is impaired by sleep deprivation, suggesting that a specific critical period exists following learning during which sleep is necessary. To elucidate the impact of sleep deprivation on long-term memory consolidation and synaptic plasticity, long-term memory was assessed when mice were sl...
results there were no significant differences between the groups in terms of the bishop’s score at the baseline (p = 0.792) and 10-12 hours after starting the intervention (p = 0.159). the bishop’s score was significantly higher in the saffron group 20 - 24 hours after the intervention was started (p = 0.029) and just after onset of active uterine contractions (p = 0.003). in the saffron group,...
objectives: to evaluate the short-term outcome of open appendectomy, the rate of negative appendectomy as well as pathology reports after surgery in patients with suspected acute appendicitis. methods: this was a retrospective cross-sectional study being performed in nemazee hospital affiliated with shiraz university of medical science during a 2-year period between 2008 and 2010. the medical r...
backgroundresistin is reported as an antagonistic hormone of insulin and in the literature. nowadays, importance of resistin is being more highlighted in the metabolism of mother and fetus during pregnancy. this study aimed to assess the level of resistin in the umbilical cord and blood sugar at birth and evaluate the association of resistin and neonatal birth weight.materials and methodsthis c...
supply chain network receding horizon control demand move suppression term supply chain networks are interconnection and dynamics of a demand network. example subsystems, referred to as stages, include raw materials, distributors of the raw materials, manufacturers, distributors of the manufactured products, retailers, and customers. the main objectives of the control strategy for the suppl...
in this study, combined effect of two essential oils, thymol and carvacrol, with different concentrations in two methods on gladiolous grandiflorous l. was investigated based on a completely randomized design with 3 replicates and four flower in each replicate. sansusi variety applied that was red. in short term method, different concentrations of thymol and carvacrolin including 25+25, 50+50 a...
