Abstract Introduction Routine postoperative blood tests (POBT) are used to evaluate the impact of surgery on pre-existing co-morbidities and detect early complications. This practice dates back an era open surgery, when loss complication rates were higher. We propose new guidelines improve specificity POBT. Method The cases 1040 consecutive patients who underwent a primary or salvage RARP at tw...

A study of the filtration behaviour of contaminated wastewater treatment sludges was conducted. The laboratory portion of the study included a series of filtration tests with different nonwoven geotextiles. Filtration performance of the sludge–nonwoven-geotextile systems was also observed in field test cells by exhuming geotextile samples from the cells after exposure followed by analysis. The ...

This paper examines the exporting behaviour of Russian manufacturers by considering the interaction of firm characteristics and external conditions. An important distinction is made between general exporting activity and export to developed countries. Firm features and specific export experience are found to be important in determining the international orientation of manufacturers and the dest...

The Penn World Tables (PWT) are an important data source for cross-country comparisons. The PWT have undergone several revisions over time and due to these revisions, some well-received evidence based on one version of the PWT may not survive when another version of the data is used. This paper explores such a possibility. Using four publicly available versions of the PWT, we first examine how ...

The first example of wholly inorganic ruthenium-containing polyoxomolybdate Cs₃Na₆H[MoVI14RuIV₂O50(OH)₂]·24H₂O (1) was isolated and systematically characterized by element analysis, infrared spectroscopy (IR), thermogravimetric analyses (TGA), X-ray photoelectron spectroscopy (XPS), energy dispersive X-ray spectroscopy (EDX) and single-crystal X-ray diffraction. Compound 1 is composed of an unp...

A growing literature relies on natural experiments to establish causal effects in macroeconomics. In diverse applications, natural experiments have been used to verify underlying assumptions of conventional models, quantify specific model parameters, and identify mechanisms that have major effects on macroeconomic quantities but are absent from conventional models. We discuss and compare the us...

abstract production is a process by which a productive activity will require some conditions (before and after the start of the production). one of the most important pre-required factors for start up a production unit is suitable business environment. one of the most important factors that must be provided after the start of production -during the production process and the time to market and ...

Abstract Introduction Metastatic breast cancer (MBC) is the main source of mortality in patients largely due to lack effective treatments. Our previous results suggest that tumour transcriptional heterogeneity drives therapy resistance and relapse. While traditional vitro human cell line models have been widely used for disease modelling, they do not faithfully recapitulate pathophysiology MBC....

This paper contributes to the conflicting international evidence on the impact of information and communication technology (ICT) on labour productivity (LP) growth. We examine the link between ICT intensity and New Zealand s LP growth in 29 industries over the period 1988–2003, and over relevant sub-periods. After deriving an ICT intensity index to classify industries into more ICT intensive an...
