background: general anesthesia draw the most commonly used modalities for post cesarean delivery pain relief is systemic administration of opioids, while the administration of small dose of intrathecal opioid during spinal anesthesia can be a possible alternative. the aim of this study was to evaluate the effects of buprenorphine on cesarean section prescribed intrathecally. methods: in this do...

Paper as a means of communication has never been superseded by the almost ubiquitous electronic media of the workplace. An interview and observational study investigates the use of paper in communication. Speculations are made on how CSCW systems can incorporate these results to facilitate communication and collaboration.

A series of new 2-(phenylthio) benzoylaryl hydrazones were synthesized by acid-catalyzed condensation of hydrazide 3 with corresponding aldehydes. The chemical structures of the compounds were elucidated by FT-IR, 1H-NMR and Mass spectra. All newly synthesized compounds were evaluated for their antimycobacterial activities against Mycobacterium tuberculosis H37Rv using the microplate alamar blu...

In this contribution we propose an analogue receiver that can perform turbo detection inMIMO systems. We present the case for a receiver that is built from nonlinear analogue devices, which perform detection in a “free-flow” network (no notion of iterations). This contribution can be viewed as an extension of analogue turbo decoder concepts to include MIMO detection. These first analogue implem...

This paper presents differential frequency-to-voltage (F/V) and voltage-to-frequency (V/F) converters employing single CMOS Field Programmable Analog Array (FPAA) device. The proposed electronic circuits are based on charge-balance conversion method. The F/V converter basically consists of analogue comparator, differentiator that detects the rising and falling edges of the shaped waveform, volt...

There are many methods on how to improve reliability of the system. One of the common methods is a concept of redundancy. Redundancy is simply the addition of information beyond what is needed for standard system operation. This information can be a physical value or electric signal, hardware element or subsystem, an application or software module. The concept of redundancy is based on Murphy’s...

A concept of linearly graded statistical models for analogue performance evaluation is proposed and a suitable technique for automatic generation of analogue performance models using support vector machines is presented. The analogue system’s behaviour is specified using VHDL-AMS descriptions. Practical application of the technique is demonstrated with a case study of automated analogue perform...

Dual spacization of publishing means emergence of digital publishing in online and offline virtual environments along with analogue publishing. Analogue publishing is a kind of publishing that is produced in the form of physical printed writings as they appear in a single paper, single or many pages newspapers and magazines and books, writings on leaves and pieces of trees, natural skin and lea...

Mathematica implementations, available by email request, of q-analogues of Gosper's and Zeilberger's algorithm are described. Nontrivial examples are given in order to illustrate the usage of these packages. The algorithms are based on a new approach to q-hypergeometric telescoping in which a new algebraic concept, q-greatest factorial factorization (qGFF), plays a fundamental role.

We define a general concept of a network of analogue modules connected by channels, processing data from a metric space A, and operating with respect to a global continuous clock . The inputs and outputs of the network are continuous streams u : → A, and the input-output behaviour of the network with system parameters from A is modelled by a function Φ : C[ , A]×A → C[ , A] (p, q > 0, r ≥ 0), w...
