Abstract The aim of this research is to review the literature for influence thickness and shape cervicalmargins on strength posterior monolithic zirconia crowns. Studies assess fracture resistance crowns with different types cervical margins, published from 2014 2020, were searched using electronic database PubMed Google Scholar following keywords: “monolithic zirconia,” “translucent,” “shoulde...

Plate reconstructions of the New Zealand region indicate substantial Cenozoic tectonic rotation of the Hikurangi margin. This study was undertaken to determine the rotational history of the northern Marlborough paleomagnetic domain in the southern part of the Hikurangi margin. Most Cenozoic rocks in the Marlborough region are unstably magnetised, and useful results were obtained only from late ...

The petrography, as well as major and trace element (including rare earth element) compositions of 10 sandstone samples from the Late Proterozoic Buem Structural Unit, southeast Ghana, have been investigated to determine their provenance and tectonic setting. The petrographic analysis has revealed that the sandstones are quartz-rich and were primarily derived from granitic and metamorphic basem...

[1] Radiocarbon measurements at ice margin sites and blue ice areas can potentially be used for ice dating, ablation rate estimates and paleoclimatic reconstructions. Part of the measured signal comes from in situ cosmogenic C production in ice, and this component must be well understood before useful information can be extracted from C data. We combine cosmic ray scaling and production estimat...

STATEMENT OF PROBLEM Ideally, tooth preparation for complete crowns should require the removal of the smallest amount possible of sound tooth structure to maximize the strength of the remaining tooth. Some preparation designs, such as the feather-edge margin, are less invasive. However, limited data are available regarding monolithic lithium disilicate crowns for molars and premolars with this ...

Analytical strengths of reinforced concrete beams and columns based on reinforcing steel stress-strain curves with and without a sharp yield plateau and the nonlinear stress-strain behavior of concrete are compared with strengths calculated in accordance with the ACI Building Code to determine the feasibility of using the 0.2% offset method to define the yield strength of reinforcing steel. Com...

Increases security of fixation in rotator cuff repair is usually achieved by increasing the strength of fixation. Paradoxically, the problem can be approached by techniques that decrease the strain at the margins of the tear so that weaker fixation will still be adequate. Such techniques provide greater safety tolerances for the strength characteristics of suture, tendon, and bone. The principl...

In most of the wireless networks, signal strength is considered as the basic criteria to initiate handover. In future generation heterogeneous wireless systems, the vertical handover between different types of networks take place to satisfy demands of users. The location and velocity of mobile terminal is expected to be available in most of the modern systems. The time to reach boundary of serv...

PURPOSE The purpose of the present study was to evaluate the flexural strength of the joint between glass-infiltrated alumina frames and the experimental adjusting agent (MA modifier) that contains alumina and magnesia. METHODS A commercially available adjusting agent (Optimizer), a slurry of alumina powder (Alumina modifier), and a bulk specimen (joint-free alumina) were used as controls. Be...

CONTEXT Poor muscle strength, functional limitations, and disability often coexist, but whether muscle strength during midlife predicts old age functional ability is not known. OBJECTIVE To determine whether hand grip strength measured during midlife predicts old age functional limitations and disability in initially healthy men. DESIGN AND SETTING A 25-year prospective cohort study, the Ho...
