The aim of this paper is to examine the effectiveness of innovative programmes in construction. The term 'best practice' is commonly used in industry in to describe and disseminate cases where high levels of performance have been achieved. Several terminologies are used to describe this phenomenon, the best practice being the most widely used term. Best practices usually stimulate a desire in o...

Many corporate events are self-selected, but the relative impact of internal (firm-specific) and external (environmental) influences on discretionary corporate decisions remains largely unknown. In this paper, focusing on corporate debt issuance, we apply the contemporary push-pull theory to establish whether bond issuance are pushed by the firms due to internal considerations, or pulled by the...

Strengthening muscles of the back may have various implications for improving functions of daily living, aiding in the transfer of power in throwing, and assist in injury prevention of the shoulder complex. While several versions of the pull-up exist, there is currently no literature comparing their differences. The purpose of this investigation was to compare the electromyographical activity o...

The Klebsiella oxytoca pullulanase secreton (type II secretion system) components PulM and PulL were tagged at their N termini with green fluorescent protein (GFP), and their subcellular location was examined by fluorescence microscopy and fractionation. When produced at moderate levels without other secreton components in Escherichia coli, both chimeras were envelope associated, as are the nat...

Accurate segregation of chromosomes in mitosis requires that spindle microtubules attach sister kinetochores to opposite poles of the mitotic spindle (biorientation). To achieve biorientation of all chromosomes, incorrect attachments are selectively destabilized, providing a fresh opportunity to biorient, whereas correct attachments are stabilized. Tension across the centromere may be the signa...

Multi-class closed queuing networks with synchronization stations find applications in analytical models of assembly systems and production systems operating under pull control policies. These queuing networks are hard to analyze exactly and therefore approximation methods must be used for performance evaluation. In this research we propose a new efficient approach based on parametric decomposi...

We analyse an assembly system fed by components produced by suppliers and operating under a pull system with random processing times. Under certain assumptions we present a performance evaluation algorithm which is based on physical decomposition of the network and use of an aggregation/disaggregation algorithm. We consider two important performance measures: system throughput and work-in-proce...

This paper describes a new approach for fast and accurate determination of the source reflection coefficient in microwave source-pull measurements. To the authors' knowledge, this is the only technique that allows the simultaneous measurement of the source and the device-under-test input reflection coefficients. A traditional vector network analyzer is used as a four-channel receiver. The calib...
