viability of probiotic bacteria in food during maintenance and time of consuming in food has become a challenge in food hygiene and technology and is important for representing their beneficial health effects. the aim of this study was to determine the survival of probiotic enterococcus faecium derived from koopeh cheese added to industrial iranian ultra-filtrated (uf) cheese and screening for ...

Despite intensive searches for therapeutic agents, few substances have been convincingly shown to enhance nerve regeneration in patients with peripheral neuropathies. Recent biochemical evidence suggests that an ultra-high dose of methylcobalamin (methyl-B12) may up-regulate gene transcription and thereby protein synthesis. We examined the effects of ultra-high dose of methyl-B12 on the rate of...

In this article, I have studied the ultra discrete limit, which is currently studied in soliton theory, from point of view of valuation theory. A quantity obtained after taking the ultra discrete limit should be regarded as non-archimedean valuation, which is related to the p-adic valuation in number theory. The ultra discrete difference-difference equations, whose domain and range are given by...

Ultra wideband communications based on chaotic signal is considered for low data rate, ranging application that is under standardization by the task group IEEE 802.15.4a. The current standard works are introduced and the proposed direct chaotic system is introduced. The PHY layer including transceiver, modem, and a ranging function are designed and implemented to realize a communication with lo...

An overview of the propagation characteristics of ultrawideband (UWB) indoor radio channels is presented with an emphasis on the spatio-temporal channel properties. Extensive measurement results are provided and practical considerations are highlighted. The insight into robust UWB communications and sensor networks, provided by channel modeling, is discussed.

remifentanil is an ultra short acting opioid that is suitable for many operations and is wildly used for induction and maintenance of anesthesia. in this article we have reported the incidence of abdominal pain after cataract surgery in patients with remifentanil based anesthesia. this study is a randomized single blind clinical trial on 300 patients who were candidates for elective cataract su...
