Forty two single-rooted teeth, prepared with the Mtwo system, were divided into three groups based on the filling method: control, "Single-cone" (n = 20) (Mtwo gutta-percha single-cone tapered according to the diameter, length and conicity of the preparation) and "Combined system" (n = 20) (BeeFill 2in1). The parameters studied were apical leakage, gutta-percha adjustment, number of voids, pres...

BACKGROUND Left ventricular size and shape are important for quantifying cardiac remodeling in response to cardiovascular disease. Geometric remodeling indices have been shown to have prognostic value in predicting adverse events in the clinical literature, but these often describe interrelated shape changes. We developed a novel method for deriving orthogonal remodeling components directly fro...

In the field of turbomachines, better engine performances are achieved by reducing possible parasitic leakage flows through the closure of the clearance distance between blade tips and surrounding casings. Together with new technologies involving higher casing conicity for improved compression rates, direct contact is now considered as part of aircraft engines normal life. In order to avoid pos...

Assessing the architectural optimality of animal constructions is in most cases extremely difficult, but is feasible for antlion larvae, which dig simple pits in sand to catch ants. Slope angle, conicity and the distance between the head and the trap bottom, known as off-centring, were measured using a precise scanning device. Complete attack sequences in the same pits were then quantified, wit...

INTRODUCTION the evaluation of the body fat distribution by anthropometry can serve to identify excess visceral fat. This diagnosis will enable implementation of specific measures to both prevent and treat excess visceral fat in postmenopausal women. OBJECTIVE the aim of this study was to analyze different anthropometric indicators and identify the best cutoff points to discriminate subjects ...

The pattern of fat distribution is related to a large number of variables of clinical importance. Many anthropometric indices have been derived which are surrogate measures of central fat distribution. However, systematic information on age variations in regional adiposity and central fat distribution is incomplete. The present study investigates the age variations in regional adiposity and fiv...

BACKGROUND This cross-sectional study aimed to evaluating the association between body adiposity markers and high-risk of coronary heart disease (CHD) in patients with type 2 diabetes. METHODS Recent adiposity markers [waist-to-height ratio, conicity index (C-index) and body adiposity index] and traditional markers [BMI, waist circumference and waist-to-hip ratio (WHR)] were measured. The 10-...

OBJECTIVE To compare the disinfecting efficacy of the sodium hypochlorite irrigation by root canal preparation with stainless steel hand files, taper 0.02 and nickel-titanium Mtwo files with taper 0.04-0.06. STUDY DESIGN 40 extracted human teeth were sterilized, and then inoculated with Enterococcus faecalis (ATCC 29212). After 6 day incubation time the root canals were prepared by hand with ...

Hypertension is among the most important risk factors for cardiovascular diseases. It was found that subjects who do vigorous physical activity, have brought down mortality and lowered danger of sicknesses are termed to be physically fit. The present study estimates blood pressure level all active Garo women self-claimed aim this paper see whether prevalence hypertension fit individuals or only...

We systematically investigate axisymmetric extremal isolated horizons (EIHs) defined by vanishing surface gravity, corresponding to zero temperature. In the first part, using Newman–Penrose and GHP formalism we derive most general metric function for such EIHs in Einstein–Maxwell theory, which complements previous result of Lewandowski Pawlowski. prove that it depends on 5 independent parameter...
