Fracture resistance of simulated incomplete vertical fractured teeth treated with different bioceramic based root canal sealers

Introduction: The aim of this study was to examine fracture resistance after filling simulated incomplete vertical fractured permanent teeth using two different bioceramic based sealers. Material and Methods: Sixty single-rooted maxillary incisors were decoronated to a length of 13 mm. The teeth were randomly divided into four groups (n=15 for each group). In negative control group, the teeth were left with no process. For positive control and two experimental groups, 45 roots were prepared by using Protaper System up to a master apical file size of F3. In these 45 roots, a simulated fracture line (6.5 mm length, 0.25 mm width) extended until the root canal space was created from the root apex towards crown. In positive control group, 15 teeth were filled with only gutta-percha. In experimental groups, first group filled with gutta-percha + Well Root ST sealer, and the other group filled with guttapercha + MTA Fillapex sealer. Each sample was tested for the fracture in universal testing machine at a crosshead speed of 1.0 mm/min. The fracture resistance of each sample was recorded, and the obtained data was analyzed statistically. Results: The highest fracture resistance value was observed for the negative control group (P<0.05). Well Root ST showed significantly higher fracture resistance in comparison to the MTA Fillapex (P<0.05). The fracture resistance was significantly higher for both sealer groups than it was for the positive control group (P<0.05). Conclusion: Well Root ST and MTA Fillapex sealer significantly increased the fracture resistance of untreated incomplete vertical fractured roots.
APPLICATION OF KALMAN FILTERS IN ORBIT DETERMINATION : A LITERATURE SURVEY

This paper was narrowed down to significant contributions in the area of Kalman filtering applications for orbit determination. Research work from 1967 to 2013 is included in this paper. It was observed that examples from 1967 demonstrate the importance of pre-flight parametric studies when orbit determination estimations are carried out in short periods. Development of the extended Kalman filter requires some proper selection of parameters that define the probability density of the initial state vector, and any other parameters required by modifications to the extended Kalman filter algorithm. This paper can be used as a foundation for further investigations in the area of orbit prediction.

DETECTION OF CAROTID ATHEROSCLEROSIS IN SYSTEMIC LUPUS ERYTHEMATOSUS AND ITS RELATION TO RISK FACTORS

Objective: to detect early atherosclerotic changes in SLE patients and to evaluate its relation to traditional cardiovascular risk factors and lupus-related factors. Methodology: Forty female SLE patients were included in this study. Their age ranged from 20 to 63 years. All of them were subjected to full history taking, thorough clinical examination, laboratory investigations, disease activity assessment using SLE Disease Activity Index (SLEDAI) and assessment of SLErelated disease damage according to the Systemic Lupus International Collaborating Clinics (SLICC) damage index. Intima-media thickness (IMT) and carotid plaques were measured with carotid B-mode ultrasound. Risk factors associated with carotid plaques and IMT were determined. They included traditional cardiovascular risk factors, SLE-related disease factors and inflammation markers. Results: Eighteen patients out of the 40 (45%) had plaques. Those patients were statistically significantly (p<0.05) older and had higher systolic and diastolic blood pressure, greater body mass index, higher levels of total cholesterol, low-density lipoprotein (LDL) cholesterol, fibrinogen and Creactive protein (CRP) than patients without plaques. The patients with plaques had a statistically significant (p<0.05) longer disease duration, higher SLICC damage score and longer duration of prednisone use than those without plaques. The mean level of IMT of the CCA showed a statistically significant increase (P < 0.05) in SLE patients as compared to controls. The IMT was statistically highly significantly (p<0.001) as correlated with the age, CRP, and SLICC damage index. Conclusions: The prevalence of the plaques in the studied SLE patients was 45%. There were statistically significant differences between the patients with and those without plaques regarding disease-related factors (disease duration, SLICC damage score and duration of prednisone use) and inflammation markers (fibrinogen and C-reactive protein). IMT of the CCA showed a statistically significant increase (P < 0.05) in SLE patients as compared to controls. The IMT was statistically highly significantly correlated with SLICC damage index. These findings show that SLE-related disease factors Detection of Carotid Atherosclerosis in SLE Al-Tanawy et al. 554 and inflammation markers are associated with carotid atherosclerosis in the SLE patients. SLE patients at risk of atherosclerosis should be examined by high resolution ultrasonography for identification of early stage atherosclerosis. Also, dampening of the inflammatory activity has a favorable impact on the progression of atherosclerosis in SLE patients.
New Synthetic Methods for 4 , 4 ’ , 5 , 5 ’-Tetranitro-2 , 2 ’-bi-1 H-imidazole ( TNBI )

Four new nitration methods for the synthesis of 4,4’,5,5’-tetranitro-2,2’bi-1H-imidazole (TNBI) were examined. TNBI was synthesized by nitration of 2,2’-bi-imidazole (BI) with the following mixtures: (CH3CO)2O/HNO3, (CF3CO)2O/ HNO3, P4O10/HNO3 and H3PO4/P4O10/HNO3. Nitration of BI with a mixture of nitric acid and acetic anhydride leads to 4,4’-dinitro-bi-imidazole. The other nitrating conditions investigated gave TNBI in lower yields (6.0-22.4%). Crystallization of crude TNBI from wet ethanol/acetone gave TNBI as its dihydrate. The structures of BI and TNBI were characterized by 1H, 13C and 15N NMR spectroscopy and elemental analysis. Friction and impact sensitivity, detonability and detonation velocity were determined for pure TNBI dihydrate.
Early Gadolinium Enhancement for Area at Risk Determination : A Preclinical Validation Study

Objectives—The aim of this study was to determine if early gadolinium enhancement (EGE) by cardiovascular magnetic resonance (CMR) imaging in a canine model of reperfused myocardial infarction depicts the area at risk (AAR) as determined by microsphere blood flow analysis. Background—It remains controversial whether only the irreversibly injured myocardium enhances when performing CMR imaging in the setting of acute myocardial infarction. Recently, EGE has been proposed as a measure of the AAR in acute myocardial infarction as it correlates well with T2-weighted imaging of the AAR, but still requires pathological validation. Methods—Eleven dogs underwent 2 hours of coronary artery occlusion and 48 hours of reperfusion prior to imaging at 1.5T. EGE imaging was performed 3 minutes after contrast administration with coverage of the entire left ventricle. Late gadolinium enhancement (LGE) imaging was performed between 10 and 15 minutes after contrast injection. AAR was defined as myocardium with blood flow (mL/min/g) <2SD from remote myocardium determined by microspheres during occlusion. The size of infarction was determined using triphenyltetrazolium chloride (TTC).

Characterization of newly isolated thermotolerant lactic acid bacteria and lactic acid production at high temperature

This study aimed to select a number of thermotolerant lactic acid bacteria for lactic acid fermentation at high temperature, and to identify these LAB strains by using 16S ribosomal RNA sequences. The fermentative ability of 16 selected strains was examined at different temperatures (37oC, 39oC and 41oC), of which, the lactic acid concentration produced by these LAB strains at 37oC ranged from 6.0 g/L to 14.1 g/L. Ten LAB strains (L2, L7, L9, L11, L21, L26, L30, L36, L37 and L52) with effective lactic acid fermentation at 37oC were chosen for identification. The selected strains were characterized as L. plantarum, L. casei, L. acidophilus, and L. delbrueckii, L. casei L9 was the superior lactic acid producing strain at both 39oC (18.9 g/L) and 41oC (18.0 g/L). Based on statistical analysis, appropriate conditions for lactic acid production by L. casei L9 at 39oC were defined as follows: pH 6.51, glucose concentration 6% (w/v) and inoculation level 2.37% (v/v). At these conditions, the validated lactic acid concentration and the yield were recorded at 21.15 g/L and 80.84%, respectively.
Trend analysis of mean and extreme rainfall in Calabria ( southern Italy )

A modification in water cycle is one of the most noticeable consequences of global atmospheric warming. Precipitation is a key point in the hydrological process and the distribution of extreme rainfall is particularly important because it may impact on water management, soil erosion and flash floods. In this paper, an analysis of mean and extreme rainfall over a region of southern Italy (Calabria) has been carried using a daily homogeneous rainfall dataset of 129 rain gauges with more than 50 years of observation for the period 1916–2006. First, a statistical analysis was performed through the Mann-Kendall test in order to detect possible trends at annual, seasonal and monthly scale. Then, a set of indices derived from the daily homogeneous rainfall time series was defined and used to examine changes in extreme rainfall through non-parametric techniques. Results show a decreasing trend for annual and winter–autumn rainfall and an increasing trend for summer rainfall. Moreover, a prevailing decreasing trend of the various indices has been detected. These results appear to be in contrast with previous large scale studies which evidenced an increase in extreme rainfall and a decrease in the yearly totals, in other areas of Southern Europe. These differences in the behaviour of extreme rainfall suggest that a detailed regional analysis is always necessary because the distribution of extreme rainfall is often linked to the morphological settings of a territory (proximity to the sea, presence of reliefs, etc.).
TCP ’ s Congestion Control Implementation in Linux Kernel

Linux kernel implements different functionalities related to the network stack. One such functionality is TCP’s congestion control. In this paper, we describe parts of the linux kernel code that deals with TCP’s congestion control implementation. Our main focus here is going through different functions that are used during TCP’s congestion control operation. Although there are many similarities between TCP’s implementation in different kernel versions, this description uses the Linux kernel v 3.6. 6.

Human capital convergence and growth: a cross country empirical investigation

This article, adapted from Tamura’s theoretical proposition, empirically investigates capital convergence in three country groups belonging to significantly different development categories: G7, developed and developing. Human capital evaluation, in this context, goes beyond enrolment and/or attainment rates. In addition to enrolments and government spending, alternative factors determining human capital effectiveness synthesize an idea of enhanced human capital proxy. Empirical results indicate moderate evidence of convergence among the three-country groups when conventional variables are included. The convergence “picture” is quite different when additional variables are empirically examined, implying the existence of a “convergence trap” caused by initial endowments on human capital.
Contemporary ethnic minority entrepreneurship in the UK

Purpose Ethnic minority entrepreneurs (EMEs) are traditionally associated with lower growth industry sectors. The purpose of this paper is to draw on the theory of mixed embeddedness to determine if more recent EMEs have been able to break out of lower growth sectors and if break out varies across ethnic minority groups. It also compares entrepreneurial quality in terms of weekly hours worked, weekly earnings and job satisfaction. Design/methodology/approach Quantitative inferential statistical analysis is undertaken on data drawn from the large scale, social sciences data set for the UK, Understanding Society. Findings The study finds that break out is not associated with being a recent EME but does vary across ethnic minority groups. Break out is found to be associated with gender, education, English language proficiency and occupational status. Some variation in entrepreneurial quality is found for both recent EMEs and across ethnic minority groups. Practical implications Understanding the nature and quality of ethnic minority entrepreneurship is important since it informs public debate about migration, informs policy and shapes activities of future EMEs. Originality/value The study provides a theoretically grounded interpretation of the explanatory variables associated with EME break out and entrepreneurial quality. Second, it provides a large confirmatory study of break out and finally, it also finds an important empirical nuance to the concept of opportunity structure by identifying a variation over time in both external and socio-demographic factors.
Effect of 6 week aerobic training in morning and evening on angiotensin-converting enzyme in postmenopausal hypertensive women

The present study designed to examine the effect a period of Exercise training in morning and evening on Angiotensin converting enzyme in post-menopausal women with hypertension. This study was Quasi-experimental study by using pretest – posttest model. The subjects were hypertensive menopausal women, aged 45-55 years. We selected 21 women that their hypertensive confirmed by physician. In this study blood samples were collected in two stages, before start training and end of training in sixth week. Subjects were randomly assigned in 3 equal group consist of: control group (n= 7), morning training group (n = 7) and evening training group (n = 7). Posttest, blood sampling was done 48 hours after last session training same the first condition and finally the results of 3 groups compare together.After 6 weeks, Angiotensin converting enzyme and levels significantly decreased in the morning and evening experimental group but no significant reductions were found in control group. There is no significant difference within the effect of two time of training (morning & evening) Angiotensin converting enzyme in hypertensive postmenopausal women.Exercise training might be considered an effective non-pharmacological intervention for attenuating or inhibiting hypertension and prevention of cardiovascular diseases by reduction of Angiotensin converting enzyme in hypertensive postmenopausal women.

Active Minorities and Social Influence

The purpose of this study is to examine the effects of decision rule, minority discrepancy from the majority, minority sex, and groupmember sex on the minority's ability to influence group members in a mock-jury deliberation of a monetary award in a civil negligence case. The mixed-sex groups deliberated under either a unanimous or majority decision rule, and were composed of 4 or 5 naive group members and a confederate (either male or female), who expressed a minority opinion that was either high or low in discrepancy from other group members. The results showed that a minority's influence is related to the interactive effects of decision rule and minority's discrepancy from the majority, such that minority influence was greatest under the combined conditions of a unanimous decision rule and low minoritymajority discrepancy, and least under a non-unanimous decision rule and low discrepancy. High discrepancy, regardless of decision rule, was associated with intermediate levels of minority influence. Although group members were influenced equally by male and female minorities, group members of both sexes perceived the female minority as less influential than the male minority. Implications for the legal and social influence literatures are discussed. ACTIVE MINORITIES AND SOCIAL INFLUENCE CHAPTER

Effects of scientific information format on the comprehension self-monitofing processes: question generation

Generating questions is a regulatory action associated with self-monitoring processes in comprehension tasks: subjects can ask information seeking questions to solve comprehension obstacles. A sequence of two related experiments were conducted to trigger, classify and analyse questions asked under different conditions: reading a text about experimental scientific devices operating, watching these devices in a DVD and manipulating them in the LAB. Students’ information seeking questions were classified using a simple taxonomy. Taking into account the multimedia learning principles, the advantages of realistic animations for understanding time-depending processes and the effect of the procedural-motor activity, were expected students would ask different questions under each of the aforementioned conditions. Results confirmed the expectations: the reading condition triggered more questions addressed to describe the entities while the watching and manipulation conditions stimulated more causal questions. In addition, the effect of prior knowledge on questions including scientific concepts was analyzed.
Productivity , Wage and Inflation Relationship for a Sample of Developed Countries : New Evidence from Panel Cointegration Tests with Multiple Structural Breaks

This paper examines the long run relationship among real wages, inflation and labor productivity over the period 1960-2011, for 11 developed economies, using a comprehensive set of empirical tests. We present a dual-level analysis: first, we consider the panel properties of the data checking for panel cointegration with structural breaks, allowing also for cross sectional dependence; hence, we examine each country separately and we investigate the properties of the variables through a set of tests, controlling also for structural breaks in order to check for robustness of data. Results do not show evidence of a long run relationship.
