The fundamental groups of most (conjecturally, all) closed 3manifolds with uniform geometries have finite complete rewriting systems. The fundamental groups of a large class of amalgams of circle bundles also have finite complete rewriting systems. The general case remains open.

This is a survey of a recent work done by the three authors, in which an analysis of geometric properties of a structure relative to a reduct is initiated. In particular, definable groups and fields in this context are considered. In a relatively 1-based theory every group is definably isogenous to a subgroup of a group definable in the reduct. For relatively CM-trivial theories (which encompas...

We study amalgams and the strong, weak, and special amalgamation bases in the varieties of nilpotent groups of class two and exponent n, where n is odd. The main result is the characterization of the special amalgamation bases for these varieties. We also characterize the weak and strong bases. For special amalgamation bases we show that there are groups which are special bases in varieties of ...

Some recent results on a general summability method, on the so-called θ-summability is summarized. New spaces, such as Wiener amalgams, Feichtinger’s algebra and modulation spaces are investigated in summability theory. Sufficient and necessary conditions are given for the norm and a.e. convergence of the θ-means.

This research was conducted to assess the ergonomic risks, the prevalence and incidence of neck shoulder back (NSB) pain among dental professionals. Subjects were 193 dentists and dental nurses working in government hospitals in Thailand. Data were collected by BRIEF (Baseline Risk Identification of Ergonomic Factors)’s survey and interviewing with the structured questionnaires. Subjects were f...

Dental biometrics used in forensic science for human identification. It utilizes dental radiographs. This radiograph provides information related to teeth shape, teeth contour and relative position of neighboring teeth, also it gives shapes of dental work like crowns, filling & bridges etc. This paper includes different method used for dental biometrics and related information. Dental biometric...

Abstract There is a natural inclusion of SL2(Z) into SL2(Z[i]), but it does not induce an injection of commutator factor groups (Abelianizations). In order to see where and how the 3-torsion of the Abelianization of SL2(Z) disappears, we study a double cover of the amalgamated product decomposition SL2(Z) ∼= (Z/4Z) ∗(Z/2Z) (Z/6Z) inside SL2(Z[i]); and then compute the homology of the covering a...

This paper examined the effect of a unique amalgam of adult learning methodologies near the end of the occupational therapy (OT) students’ didactic education as a means to enhance readiness for clinical practice. Results of quantitative and qualitative data analysis indicated that the use of standardized patients, in combination with a sequential, semistructured, and progressively challenging s...

Rhodamine B, a fluorescent substance, was used as a tracer to investigate in vitro early microleakage from around amalgam restorations in machinable mica glass-ceramic after thermal stress. Five types of amalgam, i.e., low-copper spherical, low-copper lathe-cut, high-copper admixture, high-copper lathe-cut, and high-copper spherical, were examined in the present study. The results indicated tha...
