This paper is intended to investigate the effects of infected external computers and removable storage media on the spread of computer viruses. To this end, a new dynamical model, which has four compartments, is proposed. The analysis of the model shows that the unique equilibrium is globally asymptotically stable. This result is well suited for numerical implementation. An illustration of the ...

Mader and Jackson independently proved that every 2-connected simple graph G with minimum degree at least four has a removable cycle, that is, a cycle C such that G\E(C) is 2-connected. This paper considers the problem of determining when every edge of a 2-connected graph G, simple or not, can be guaranteed to lie in some removable cycle. The main result establishes that if every deletion of tw...

This article describes the construction of the FR-3 appliance classically used in cases of Class III malocclusion characterized by maxillary skeletal retrusion. Included is a description of proper impression technique, construction bite registration, preparation of the work models, and a complete description of the fabrication of the FR-3 appliance. Specific steps in the clinical management of ...

In an era of implants and fixed prosthesis, removable partial dentures are still a treatment of choice for a wide range of patients and clinicians. As every other treatment option, removable prosthesis also has some disadvantages. But with introduction of flexible partial dentures, many of the disadvantages of conventional acrylic and cast partial dentures are taken care of. This article discus...

Literary data testify to the significant prevalence of dental implantation method solve problem permanent prosthetics in partial and complete anodontia. However, a array information needs systematization generalization, taking into account specifics providing care by institutions different regions. The authors conducted retrospective study main statistical regularities based on results 32 cases...

Power management in homes and offices requires appliance usage prediction when the future user requests are not available. The randomness and uncertainties associated with an appliance usage make the prediction of appliance usage from energy consumption data a non-trivial task. A general model for prediction at the appliance level is still lacking. In this work, we propose to enrich learning al...

The loss of multiple primary molars in the primary or transitional dentition will, in many instances, lead to disturbances of the developing dentition. To prevent this, an appliance can be constructed to maintain the relationship of the remaining teeth and to guide the eruption of the developing teeth. Traditionally, the treatment of choice for maxillary loss is the placement of a Nance applian...

UNLABELLED While utilizing removable dentures, regardless of whether the dentures are acrylic or fabricated of eclipse resin, the need for their filling-relining or their repair frequently arises. The purpose of this study is to display the technicalities of the procedure for rebasing and relining of removable light curing eclipse denture resin. MATERIAL AND METHODS This study presents cases ...

Network Appliance recently began shipping a new kind of network server called an NFS file server appliance, which is a dedicated server whose sole function is to provide NFS file service. The file system requirements for an NFS appliance are different from those for a general-purpose UNIX system, both because an NFS appliance must be optimized for network file access and because an appliance mu...

A group of destructive changes occurring in jaws in patients with maxillary complete dentures and mandibular removable partial dentures (bilaterally) has been described in the literature as the combination syndrome. However, this condition is not clinically observed in all patients. The aim of this study was to establish the prevalence index on signs of combination syndrome and to verify whethe...
