background and aims: one of the main goals of standard orthodontic treatment is having the roots of teeth adjacent to extraction sites parallel to each other. the purpose of this study was to compare standard edgewise and preadjusted straight wire (mbt) methods in achieving this goal. materials and methods: for comparing root parallelism, 228 maxillary quadrants and 225 mandibular quadrants of ...

The ability to predict the geometry of weld bead plays a key role in accurate path planning and determination welding parameters wire arc additive manufacturing. However, little attention has been paid its prediction when deposition is not straight. Thus, this work focuses on 3D reconstruction based path. One main findings paper that shape changes from symmetrical cross-section straight portion...

a detailed knowledge of root canal anatomy is a prerequisite for successful endodontic treatment. such information is highly dependent upon the ethnicity of the population of interest. lack of sufficient national information concerning internal anatomy can lead clinicians to increase their rate of treatment success. the aim of this study was to evaluate external root morphology and root canal a...

D eterrence is based on the notion that people consciously try to avoid pain and seek pleasure. It follows that by making a choice painful enough—such as the choice of crime—individuals will choose not to engage in the act. Across society as a whole, this perspective would predict that crime rates would be lowest in those places where offending evokes the most “pain” (or costs) and highest in t...

Straight skeleton (Angular Bisector Network, ABN) of a planar polygon, which can be grasped as a modi cation of a planar Voronoi diagram without parabolic arcs, has been successfully used by Oliva et al. [5] as a part of a system for three dimensional reconstruction of objects from a given set of 2D contours in parallel cross sections. The algorithm itself is used for the construction of interm...

A straight line triangle representation (SLTR) of a planar graph is a straight line drawing such that all the faces including the outer face have triangular shape. Such a drawing can be viewed as a tiling of a triangle using triangles with the input graph as skeletal structure. In this paper we present a characterization of graphs that have an SLTR. The charcterization is based on flat angle as...

A metric space X is straight if for each finite cover of X by closed sets, and for each real valued function f on X , if f is uniformly continuous on each set of the cover, then f is uniformly continuous on the whole of X . A locally connected space is straight iff it is uniformly locally connected (ULC). It is easily seen that ULC spaces are stable under finite products. On the other hand the ...

Non-somatic causes of pain may aggravate painful complaints and complicate the conservative management of diseases such as lumbo-sacral disk root disease. The two-point discrimination test has been used for assessment of diseases, which change patients' skin sensation. This study aims to find out how applicable is two-point discrimination test in the conservative treatment of lumbo-sacral disk ...

Non-exclusive sexuality identity labels such as “mostly straight” and gay” describe distinct sexualities. While research documents their existence distinctiveness, little focus has been given to friendship dynamics with these groups on a heteronormative bias. In this study, we use data collected 25 men non-exclusive sexualities from university in the northeastern United States examine intimacy ...
