در این مقاله، مسئلۀ برنامهریزی یکپارچۀ منابع (irp) با استفاده از نوعی مدل بهینهسازی با حداقل هزینه، مدلسازی شده است. در این مدل، تابع هدف مجموع هزینههای سرمایهگذاری، بهرهبرداری و تعمیرات و نگهداری منابع سمت تولید و همچنین هزینۀ اجرای برنامههای مدیریت بار است. قابلیت اطمینان سیستم، با استفاده از شاخص های مقدار انتظاری انرژی تأمین نشده (eens) و احتمال تأمین نشدن بار (lolp)، برآورد و تأمی...
Enteric nervous system (ENS) is a network made of neuronal cells and nervous fibers. There are two plexuses: myenteric of Auerbach and sub mucous of Meissner and Henle. Many substances are involved in neurotransmission at ENS level. ENS assures all gastrointestinal system functions: digestion, absorption, etc. Our study is made on 23 human fetal specimens at different ages of evolution with cro...
The enteric nervous system (ENS) in vertebrates is derived from the neural crest and constitutes the most complex part of the peripheral nervous system. Natural and induced mutagenesis in mammals has shown that the tyrosine kinase receptor RET and its functional ligand glial cell line-derived neurotrophic factor (GDNF) play key roles in the development of the ENS in humans and mice. We have dev...
مفهوم «امنیت انرژی» در سال های اخیر به یکی از مفاهیم مهم و بحث برانگیز در روابط بین الملل و اقتصاد انرژی تبدیل شده است. ادبیات این مفهوم بیشتر در اروپا توسعه یافته است؛ زیرا کشورهای اروپایی بخش مهم نیازهای انرژی خود را از راه واردات تأمین میکنند. از این جهت روسیه که یکی از مهمترین تأمین کنندگان انرژی اتحادیة اروپا به شمار میرود، از اهرم انرژی برای نزدیکی بیشتر به اروپا استفاده میکند. در این...
Abstract Background Retrograde drilling in osteochondrosis dissecans (OCD) is a widely used surgical intervention. A radiation-free electromagnetic navigation system (ENS)-based method was compared with the standard freehand fluoroscopic (SFF) regarding clinical applicability. Methods We performed cohort study at department of Orthopaedics Level 1 children’s hospital 40 patients (20 SFF and 20 ...
We present the Entity Name System (ENS), an enabling infrastructure, which can host descriptions of named entities and provide unique identifiers, on large-scale. In this way, it opens new perspectives to realize entity-oriented, rather than keyword-oriented, Web information systems. We describe the architecture and the functionality of the ENS, along with tools, which all contribute to realize...
LIP UMR CNRS / ENS Lyon / UCB Lyon 1 / INRIA 69007 Lyon E-mail : Christophe [email protected], [email protected] The advent of parallelism in supercomputers, in embedded systems (smartphones, plane controllers), and in more classical end-user computers increases the need for high-level code optimization and improved compilers. Being able to deal with the complexity of the upcoming softw...
The enteric nervous system (ENS) poses the intrinsic innervation of the gastrointestinal tract and plays a critical role for all stages of postnatal life. There is increasing scientific and clinical interest in acquired or age-related gastrointestinal dysfunctions that can be manifested in diseases such as gut constipation or fecal incontinence. In this study, we sought to analyze age-dependent...
Congenital diseases of dysmotility are a serious problem in children and, potentially, also in adults. Advances have recently been made in understanding one cause of pediatric dysmotility, Hirschsprung’s disease, which is the most visible congenital defect of the enteric nervous system (ENS). Although the diagnosis of Hirschsprung’s disease is sometimes missed, and the length of involved gut ma...
