Software development relies critically on code reuse, which software engineers typically realise through handwritten abstractions, such as functions, methods, or classes. However, such abstractions can be challenging to develop and maintain. One alternative form of re-use is copy-paste-modify, a methodology in which developers explicitly duplicate source code to adapt the duplicate for a new pu...

The Subtext project seeks to make programming fundamentally easier by altering the nature of programming languages and tools. This paper defines an operational semantics for an essential subset of the Subtext language. It also presents a fresh approach to the problems of mutable state, I/O, and concurrency. Inclusions reify copy & paste edits into persistent relationships that propagate changes...

PURPOSE The aim of this study was to evaluate, in vitro, the quality of calcium hydroxide [Ca(OH)(2)] paste filling (Ultracal, Ultradent) associated or not with Ca(OH)(2)-containing gutta-percha points (Calcium Hydroxide Plus Points, Roeko) in curved root canals. MATERIAL AND METHODS One hundred and twenty roots of extracted human teeth, randomly divided into three curvature ranges (mild - 0 ...

OBJECTIVE This study was designed to investigate a possible relationship between the duration of the oral and pharyngeal phases of swallowing. INTRODUCTION The oral and pharyngeal phases of swallowing are independent from each other but may be related. METHODS We used videofluoroscopy to evaluate 30 healthy volunteers between 29 and 77 years of age who swallowed 5- and 10-ml liquid and past...

A critical evaluation of shrinkage of saturated cement paste due to thermal cycling, increased ion diffusion through saturated cement paste due to thermal cycling, Powers water permeability data of dried and resaturated cement paste, and dying shrinkage data of Pickett and others reveals an intrinsic instability of Portland cement pastes. The instability is such that even a very mild treatment ...

Figure 1. Marked soft tissue irritation in retromylohyoid area with calcium hydroxide paste. The most critical time in the success or failure of a denture is the adjustment period, and the most common complaint is pain caused by soft tissue irritation. The clinician is responsible for the care of the patient throughout this period; however, detecting and transferring the irritated area to the d...

Software evolves continuously. As software evolves, it’s code bases require implementations of new features. These new functionalities are sometimes mere extensions of existing functionalities with minor changes. A commonly used method of extending an existing feature into a similar new feature is to copy the existing feature and modify it. This method of extending feature is called “Copy-paste...

We study the combined and separate effects of three parts of finite multi-testtube cut and paste DNA computing. First, we reformulate the ideas of Csuhaj-Varjú, Kari, and Pǎun [1], Freund [3], and Priese, Rogojine and Margenstern [10] about multi-test-tube splicing DNA computing in terms of cutting and pasting as in Pixton’s work. Pixton shows [8, 9] that with finite cutting and pasting only re...

This mini review describes the results regarding the voltammetric determination of micromolar, submicromolar and nanomolar concentrations of various fluoroquinolones antibacterial agents using both traditional hanging mercury drop electrode, carbon paste electrode, glassy carbon paste electrode and chemically modified electrodes. We concentrate on the interaction of quinolones with DNA in solut...
