Conventional orthodontic appliances use mechanical forces to modify the position of tooth/ teeth into a more favorable position. However, scope these fixed are greatly restricted by certain morphological conditions which caused due deviations in developmental process or neuromuscular capsule surrounding orofacial skeleton. To overcome this drawback, myofunctional came being. These considered be...

We study qualitative properties for nonnegative solutions to a conformally invariant coupled system of fourth order equations involving critical exponents. For defined in the punctured space, there exist essentially two cases analyze. If origin is removable singularity, we use an integral moving spheres method prove that non-singular are rotationally invariant. More precisely, they product sphe...

When periodontal disease is diagnosed, it difficult to predict the clinical response of treatment a tooth over time because result affected by several factors and will depend on maintenance support treatment. Rehabilitation with removable dental prostheses, fixed implants makes possible restore function esthetics patients loss due disease. The predictive in periodontitis should be assessed dent...

BACKGROUND The objectives of this study were to evaluate retention procedures and protocols which are used by the orthodontists in Lithuania and to identify commonly used types of dental retainers. METHODS One hundred seven questionnaires in total with 28 multiple-choice questions were sent to all members of the Lithuanian Orthodontic Society. The questionnaire was organized into eight sectio...

Let M be a closed maximally complex submanifold of some relatively compact open subset A of the boundary of a strictly pseudoconvex domain Ω of C. We find an open domain à of Ω, depending only on Ω and A, and a complex variety with isolated singularities W ⊂ à such that bW ∩ A = M .

Removable memory device (RMD) is one of main way for propagating computer virus. In this paper, a dynamic propagation model of RMD-virus with varying population size is discussed. Unlike other computer virus propagation models, the proposed model mainly considers the RMD-virus propagation between host and RMD, which is embodied by introducing the RMD state and new propagation rate. Furthermore,...

The abstract boundary construction of Scott and Szekeres is a general and flexible way to define singularities in General Relativity. The abstract boundary construction also proves of great utility when applied to questions about more general boundary features of space-time. Within this construction an essential singularity is a non-regular boundary point which is accessible by a curve of inter...

1 Introduction Traditionally, systems for large-scale data storage have been based on removable media such as tape and, more recently, optical disk (CD, DVD). While the need for increased storage capacity has never been greater, the inadequacies of traditional approaches have never been more apparent. This is especially true for fixed-content data: new government regulations and increasingly co...
