A Comprehensive Survey on Resource Allocation Strategies in Fog/Cloud Environments.

The growing number of connected objects has allowed the development of new applications in different areas. In addition, the technologies that support these applications, such as cloud and fog computing, face challenges in providing the necessary resources to process information for different applications due to the highly dynamic nature of these networks and the many heterogeneous devices involved. This article reviews the existing literature on one of these challenges: resource allocation in the fog-cloud continuum, including approaches that consider different strategies and network characteristics.

A DFT study of addition reaction between fragment ion (CH₂) units and fullerene (C₆₀) molecule.

The theoretical study of the interaction between CH(2) and fullerene (C(60)) suggests the existence of an addition reaction mechanism; this feature is studied by applying an analysis of electronic properties. Several different effects are evident in this interaction as a consequence of the particular electronic transfer which occurs during the procedure. The addition or insertion of the methylene group results in a process, where the inclusion of CH(2) into a fullerene bond produces the formation of several geometric deformations.

DFT: a dynamic study of the interaction of ethanol and methanol with platinum.

The interaction between alcohol molecules and platinum (Pt) was studied using molecular dynamics (MD; Born-Oppenheimer method). Alcohol molecules like ethanol and methanol present a similar molecular structure, with a methyl group (CH(3)) at one end and a fragment of hydroxyl (OH) at the other. This fact generates two orientations that are considered in the interaction with Pt.

Localized gingival recessions treated with the original envelope technique: a report of 50 consecutive patients.

Background: The surgical techniques used to treat gingival recession have changed considerably in the last 50 years. The envelope technique described nearly 20 years ago still offers an excellent alternative for the problem of recession. The purpose of this retrospective study is to show the results of 115 recession sites treated in 50 patients using the envelope technique.

Immediate replacement of single upper posterior teeth: a report of cases.

Background: The immediate replacement of upper molar teeth with implants poses a significant challenge to the clinician because of its sinus involvement.

Purpose: The purpose of this article is to report a protocol in which single molar teeth are replaced immediately with implants, minimizing the need for other surgical procedures.

Materials And Methods: This protocol has been employed in eight cases.

Preservation of esthetics with implant dentistry: a clinical report.

Background: The replacement of single teeth with implants in the anterior maxilla poses a significant challenge to the clinician because of its esthetic implications.

Purpose: The purpose of this article is to report a protocol in which single teeth are replaced by implants and temporarily restored without load, immediately after extraction.

Materials And Methods: Between June 2001 and July 2002, 16 cases were followed up in which this protocol was used.
