Building conservation is a cultural phenomenon in the urban landscape, occurring by means of turning culture into a tradable product. In the article we illustrate that building conservation, serves the wealthy by means of the symbolic value given to these buildings and their surroundings, while those who pay the price are the poor. The conservation plan of Tel Aviv is examined against the failu...

application of phosphorus (p) fertilizers as solid or liquid fertilizers to soils leads to re-actions of orthophosphate ions with various soil components which remove p from the so-lution phase and convert it to less soluble phosphates. this study was aimed at determin-ing soil properties that affect the rate of phosphate retention in 28 contrasting calcareous soils from different geographical ...

A clock and data recovery (CDR) circuit using a new halfrate wide-range phase detection technique has been developed. Unlike the conventional three-state phase detectors, the proposed detector is applicable to the Non-Return-to-Zero (NRZ) data stream and also has low jitter and wide capture range characteristics. The CDR circuit was implemented in a 0.35-μm N-well CMOS technique. Experimental r...

An injection-locked clock recovery circuit (CRC) with quadrature outputs based on multiplexed oscillator is presented. The CRC can operate at a half-rate speed to provide an adequate locking range with reasonable jitter and power consumption because both clock edges sample the data waveforms. Implemented by 0.18-μm CMOS technique, experimental results demonstrate that it can achieve the phase n...

abstract aim and background:   this study is aimed to assess the effect of aminophylline (1mg/kg) on reversal of the sedative effects of propofol and the recovery time in patients under propofol anesthesia. due to the known effects of aminophylline on myocardial contractility and the increase in cardiac output, its effects on hemodynamic changes of propofol are also assessed. methods and materi...

This paper provides a review of disaster tolerant Information Technology (IT). The state of traditional disaster recovery approaches is outlined. The risks of IT application downtime attributable to the increasing dependence on critical information technology operating in interdependent, interacting complex infrastructure systems is reviewed. General disaster tolerance techniques are summarized...

Version 1c, 4 May 2010 High speed serial data links are expected to transmit data at very high rates with very high fidelity. Today speeds approaching 10 Gb/s are becoming common with 40 Gb/s on the horizon. Typically, a maximum bit-error rate (BER) of 10–12-10–15 is required. Verifying such a small BER with direct simulation is quite impractical. Instead, a procedure is presented that separate...
