The 'waterfall effect' is a descriptive term to indicate a sliding ptosis of parenchymal breast tissue over a fixed or encapsulated implant. It occurs more frequently than surgeons anticipate and especially over the longer term after augmentation. Certain breast implants are more prone to contribute to this problem as are implants placed in submuscular pockets that ride high, especially in wome...

This study examines the traditional approach to software development within the United Kingdom Government and the accreditation process. Initially we look at the Waterfall methodology that has been used for several years. We discuss the pros and cons of Waterfall before moving onto the Agile Scrum methodology. Agile has been adopted by the majority of Government digital departments including th...

Our team helps Tieto teams distributed over the entire world to set up effective way of working applying Agile, Lean, Kanban and Global sourcing principles. In May 2009 we have faced our biggest challenge. Energy sector product, 30 people in Norway, Sweden and Finland with waterfall way of working organized into regular 6 sub-applications wanted to achieve quite challenging targets. To grow to ...

We examined the "vascular waterfall" hypothesis, which proposes that coronary flow is unaffected by elevations in outflow pressure until the latter reaches a critical threshold level, in 29 isolated canine hearts. In fibrillating hearts vasodilated with adenosine or carbocromen, coronary flow and the coronary pressure-flow relation were not affected by changes in great cardiac vein pressure (PG...

In a recent paper by Lyon et al. (Flow through Collapsible Tubes at Low Reynolds Numbers. Circ Res 47: 68-73, 1980), the authors contend that waterfall models adequately predict flow through a Starling resistor only for Reynolds numbers <1. Their basic conclusion was that caution should be used when applying waterfall models to the mammalian circulatory system since Reynolds numbers are usually...

Imagine that you are in the market for some custom software. You’ve issued an RFP, prohibited any contact between bidders and your organization, and demanded a single price for the whole effort. In response, one of the prospective contractors pitches you the following scenario. “For US$35,000,” the contractor’s account executive says, “an cross-functional team of our best people will work with ...

Given recent observational results from the BICEP2 and Planck collaborations regarding the ratio of power in tensor to scalar modes in the cosmic microwave background radiation, and the implications of this ratio for the possible existence of large gravity waves resulting from inflation, it is of current interest to investigate models of inflation which are capable of producing large gravity wa...

Modern languages are typically supported by managed runtimes (Virtual Machines). Since VMs have to deal with many concepts such as memory management, abstract execution model and scheduling, they tend to be very complex. Additionally, VMs have to meet strong performance requirements. This demand of performance is one of the main reasons why many VMs are built statically. Thus, design decisions ...

The objective of this article is to prepare a time-inhomogeneous intensity model for valuing cash-flow CDOs, which explicitly incorporates the credit rating of the firms in the collateral portfolio as the indicator of the likelihood of default. Our model can prove very useful for the pricing, structuring, rating and risk management of CDO notes, whenever the legal structure of the transaction, ...

Introduction The mineralization at Waterfall Gorge was first exploited in 1865 for its copper. In 1908 nickel was reported in the ore, and in 1950s PGEs were reported (Maske and Cawthorn, 1986). Quantitative data on all these metals was presented by Lightfoot et al. (1984). Despite subsequent exploration no further economic resources have been defined, although geochemical modeling suggests the...
