Purpose:Dental shade guides are commonly used for color determination and should be disinfected and sterilized. The purpose of this study was to evaluate the color change of Vita 3D Master shade tabs after disinfection and sterilization. Material and methods:Overall, 98 samples (shade tabs) were randomly selected from 14 new, unused Vita 3D sets, including the following shades: 2M1, 3L1.5, 3M1,...

T he unique geometry of carbon nanotubes allows them to be used as drug-delivery vehicles or ‘nanocarriers’ in cancer therapy and other areas of medicine1. Nanocarriers work by bringing drugs directly to diseased areas of the body, thereby minimizing the exposure of healthy tissues while increasing the accumulation of the drug in the tumour area. This reduces both the dose necessary for treatme...

Abstract T-foil and stern tabs were installed on a wave-piercing catamaran (Incat Tasmania Hull 061) to improve ship motions passenger comfort. More than 40 total effective hours of sea trials conducted by the US Navy in 2004, encountering states 4–5 Atlantic Ocean near United Kingdom. In this paper influence ride-control system (RCS) heave pitch response amplitude operator (RAO) full-scale hig...

In our research, we focus on improving the user model by using novel sources of user feedback – tabbed browsing behavior of the users (also called parallel browsing). The tabbing is nowadays established as the more accurate description of browsing activities than the previous linear representation. Users take advantage of multiple tabs in various scenarios, by which they express different relat...

statement of the problem: implant-retained overdenture can improve the stability of dentures and prevent bone loss. overdenture-wearing patients need special hygiene care. purpose: the aim of this study was to evaluate the effects of various denture cleansers on the retention of dio orange o-rings. method and materials : in this experimental study, 40 dio orange o-rings were divided into 4 grou...

An account is given of a theoretical flutter investigation in connection with an accident to a Sea Venom aircraft. The investigation covers both symmetric and antisymmetric flutter of the tailplane-elevator-tab system. The main (symmetric) calculations include six degrees of freedom, comprising three structural modes and movements of elevator, spring-tab and trim-tab respectively. The parameter...

Age differences were examined in affective processing, in the context of a visual search task. Young and older adults were faster to detect high arousal images compared with low arousal and neutral items. Younger adults were faster to detect positive high arousal targets compared with other categories. In contrast, older adults exhibited an overall detection advantage for emotional images compa...
