AIMS To determine whether the use of negative pressure ventilation (NPV) was associated with a lower rate of endotracheal intubation in infants with recurrent apnoea secondary to acute bronchiolitis. METHODS Retrospective review of two paediatric intensive care units (PICU) databases and case notes; one PICU offered NPV. RESULTS Fifty two infants with bronchiolitis related apnoea were admit...

Photosynthetic vegetation (PV) and non-photosynthetic vegetation (NPV) are important ground cover types for desertification monitoring and land management. Hyperspectral remote sensing has been proven effective for separating NPV from bare soil, but few studies determined fractional cover of PV (f pv) and NPV (f npv) using multispectral information. The purpose of this study is to evaluate seve...

Invasive ventilation is associated with both pulmonary and non-pulmonary complications. There has been a renewed interest in the use of negative pressure ventilation (NPV) for various medical conditions to minimise the complications associated with positive pressure ventilation. The routine use of NPV in an ICU setting still requires further studies and research. In this article, the authors re...

The NPV technique measures the present value of the future cash flows that a project will produce. A positive NPV means that the investment should increase the value of the firm and lead to maximizing shareholder wealth. A positive NPV project provides a return that is more than enough to compensate for the required return on the investment. Thus, using NPV as a guideline for capital investment...

Although consumer financial decision making has attracted renewed attention from marketing researchers, issues of consumer decumulation of retirement wealth have remained relatively unexplored. Research on decumulation presents an interesting problem for both behavioral and quantitative marketing researchers; it is a choice problem with large stakes, multiple sources of uncertainty, and difficu...

The rationale for using NPV for project evaluation appears weaker than ever. Authoritative texts in attempting to extend NPV by the inclusion of options, strategy and games far from enriching the model present evermore loosely argued rationales that are becoming contradictory. A brief review helps to understand how this state of affairs has arisen and how future analysis might develop. As an ad...
