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...

INTRODUCTION This article reviews the literature pertaining to bismuth iodoform paraffin paste. OVERVIEW Bismuth iodoform paraffin paste is used in most otolaryngology departments on a daily basis. Questions about its properties are common in postgraduate otolaryngology examinations. This article reviews bismuth iodoform paraffin paste's current and historical usage, constituents, properties,...

the effects of adding nano-silica particles on the compressive strength and water permeability of concrete and its comparison with that of micro-silica were investigated in this work. the effect of combination of nano- silica and micro-silica were also studied in this work, which resulted in an increase in compressive strength of concrete in comparison with other concrete specimens tested in th...

OBJECTIVE This study determined environmental pH changes after root canal dressing using 3 types of commercial calcium hydroxide pastes. METHODS Thirty-two extracted single-rooted human premolars with 1 straight root canal were selected. Standard cavities were prepared on root surfaces. All root surfaces, excluding the cavities, were covered with nail polish. Root canals were prepared using t...

UNLABELLED Peanut skins (PS) are a good source of phenolic compounds. This study evaluated antioxidant properties and flavor of peanut paste and peanut butter enhanced with peanut skins. PS were added to both materials in concentrations of 0.0%, 0.5%, 1.0%, 5.0%, 10.0%, 15.0%, and 20.0% (w/w). PS, peanut paste, and peanut butter used in the study had initial total phenolics contents of 158, 12....

I i rbed o s ( a bstract alcium hydroxide [Ca(OH) 2] has been widely used hortor long-term intracanal antibacterial dressi aterial after endodontic treatment. In general w sed in endodontics, Ca(OH) 2 paste is composed of t owder, a vehicle, and a radiopacifier. To provide iopacity, barium sulfate (BaSO 4) powder is usual dded to the paste. In this case report, BaSO 4:Ca(OH)2 owders (ratio 1:8)...
