Mapping “soft” data, data that are inaccurate, uncertain, or of dubious lineage, presents several challenges to cartography. A review of existing research shows that authors have focussed on issues of parallel vs. active display for uncertainty, which visual variable are appropriate for uncertainty data and the need to use additional display variables such as animation and focus to display unce...

The aim of this in vitro study was to evaluate and compare the color stability of different esthetic restorative materials (one microfilled composite, one nanofilled composite, one nanoceramic composite, one microfilled hybrid composite, one microfilled hybrid composite, one nanohybrid Ormocer based composite and one supra-nano spherical hybrid composite) after exposure to different staining so...

introduction monitoring of salt lake dry areas is an important parameter for sustainable development and environmental protection. monitoring of dried areas of the salt lake requires extraction of thematic maps at different times. powerful tool for remote sensing of the earth different ecosystems, such as playa environments, is to produce valuable and useful data. the major causes of widespread...

We aimed to evaluate the color stability of bulk-fill and conventional composite resin with respect to thickness and storage media. Twenty specimens of a conventional composite resin (6 mm diameter and 2 mm thick) and 40 specimens of the bulk-fill Tetric EvoCeram composite resin at two different thicknesses (6 mm diameter and 2 mm thick or 4 mm thick, n = 20) were prepared. The specimens were s...

Perfusion, permeability and magnetic resonance spectroscopy (MRS) are now widely used in the research and clinical settings. In the clinical setting, qualitative, semi-quantitative and quantitative approaches such as review of color-coded maps to region of interest analysis and analysis of signal intensity curves are being applied in practice. There are several pitfalls with all of these approa...

Thyme Essential oils (EO) with antimicrobial and antioxidant properties are widely used in pharmaceutical, cosmetic, and perfume industry. It is also used for flavoring and preservation of several foods. Nowadays, packaging research is receiving a considerable attention due to the development of eco-friendly materials made from natural polymers such as starch and chitosan. In this study Thymus ...

An element of a group is reversible if it is conjugate to its own inverse, and it is strongly reversible if it is conjugate to its inverse by an involution. A group element is strongly reversible if and only if it can be expressed as a composite of two involutions. In this paper the reversible maps, the strongly reversible maps, and those maps that can be expressed as a composite of involutions...

The paper presents an interactive approach for guiding the user’s select of color-maps in visualization. PRAVDAColor, implemented as a module in the IBM Visualization Data Explorer, provides the user a selection of appropriate color-maps given the data type and spatial frequency, the user’s task, and properties of the human perceptual system.
