Effect of three glass fiber post removal techniques on the amount of removed root dentin ''An in vitro study

Introduction: Glass fiber posts removal is a major obstacle in nonsurgical endodontic retreatment. The currently used removal techniques cause tooth structure loss in different amount. The aim of this study was to evaluate three glass fiber post removal techniques according to their effect on the amount of removed root dentin. Materials and Methods: Endodontic treatment was accomplished for 45 extracted single-rooted teeth. The teeth were decoronated and roots were cut apically at (11 mm) then fiber post spaces were prepared. Photographs of the apical cross-section for post space were taken using a camera at a magnification of 40. Fiber posts were cemented with dual cure resin cement. Then, the samples were divided into three groups (n = 15) depending on the fiber post removal technique: Group (I) DT post removal Kit, Group (II) ultrasonic tips E4D and Group (III) diamond bur and Peeso reamer. Posts were removed and images of the previous section were taken under the same magnification. AutoCAD program was used to compare the spaces difference between before and after removal images. Data were subjected to statistical analysis. Results: The average percentage of removed dentin was (1.89, 0.48, 0.09) cm2 in Groups I, II, and III, respectively. Group I showed the highest amount of removed dentin comparing to other groups, but no significant difference between Group II and Group III was recorded (P = 0.000). Conclusion: DT post removal kit group was the most aggressive technique for removing glass fiber.
Real-time ultrasound-guided spinal anaesthesia vs pre– procedural ultrasound-guided spinal anaesthesia in obese patients

Background and Aims: Spinal anaesthesia is conventionally performed using a landmark-guided midline approach. These surface landmarks may be absent, indistinct or distorted in the presence of obesity, previous spinal surgeries, deformities, or degenerative changes associated with ageing. In the present study, we compared the efficacy of real-time ultrasound (RUS)-guided paramedian approach, and pre-procedure ultrasound (PUS) landmark-guided paramedian approach in obese patients. Methods: Eighty patients with body mass index (BMI) >30 kg/m2 were included in the study. The participants were randomly assigned to two intervention groups, i.e., RUS and PUS approach. The primary end point was to attain a successful lumbar puncture. Variables like the number of attempts, the number of passes, the time taken for identifying landmark(s), and time for a successful lumbar puncture(s) were secondary end points and were recorded in both the groups. Results: The median number of attempts were 4 (IQR 2-4) and 2 (IQR 1-2), respectively, in the PUS and RUS group (P-value < 0.001). The median number of passes, the median time for identifying space, and the time for successful lumbar puncture was statistically significantly less in the RUS group, than the PUS group. Conclusion: The time taken for the identification of the space, the number of attempts, number of passes, and the time taken for successful lumbar puncture was more in the PUS group as compared to the RUS group.
Evaluation of predictors of patency of infrapopliteal angioplasty in diabetic occlusive lesions

Backgroundand purpose To evaluate technical success as a predictor of patency of infrapopliteal angioplasty in diabetic occlusive lesions. Patients and methods This prospective study included 134 cases (critical limb ischemia 100%) that underwent tibial percutaneous transluminal angioplasty. The end point of follow-up was major adverse clinical outcome of the treated segment, which was defined as healing or clinical failure, that is, need for subsequent intervention such as endovascular or surgical revascularization or amputation. Follow-up period was 12 months. Results All patients passed uneventful intervention course, and technical success was reported in 128 (95.5%) cases with minimal complications in ∼36 (26.9%) cases. There was a significant correlation between major adverse clinical outcome and major tissue loss, lesion occlusion, subintimal intervention, and complications (P=0.0001, 0.002, 0.001, and 0.002, respectively). Conclusion There are many predictors of patency after infrapopliteal angioplasty in diabetic occlusive lesions, including patient risk factors. Moreover, type and site of the lesion and technical success may play a role. However, the most important predictors of patency are major tissue loss, lesion occlusion, subintimal intervention, or complications.
Elastic softening of metamict titanite CaTiSiO5: Radiation damage and annealing

Abstract We have measured the elastic response of radiation-damaged titanite, CaTiSiO5, as a function of thermal annealing. We estimate the bulk modulus of the damaged samples (-24% amorphous) to be 85 GPa, which is much softer than for undamaged crystalline titanite [131.4 GPa; Angel et al. (1999)]. Conversely, the lowest shear modulus of the radiation-damaged material is 52-58 GPa, which is harder that of the undamaged titanite, 46-52 GPa. The bulk and shear moduli of the radiation-damaged materials are close to those of thermal titanite glass, Bglass ≈ 75 GPa and Gglass ≈ 47 GPa, and are much smaller than expected based on other radiation-damaged materials such as zircon (ZrSiO4). Surprisingly, annealing of the damaged titanite in the range 600 < T < 1000 K leads to additional massive softening of the shear moduli. During annealing the shear modulus of titanite sample 1 softened from 58 to 29 GPa, and sample 2 softened from 52 to 19 GPa. The temperature range for the softening coincides with that found for crystallization of the amorphous regions, as measured previously by diffraction and spectroscopic methods. In contrast to the huge softening of the ultrasonically measured shear modulus, the calorimetrically measured Debye temperature θD increases by -5%, suggesting a small intrinsic hardening of the acoustic shear modes. Additional heating to 1473 K leads, in one titanite sample, to a steep increase of the shear modulus to values much larger than that of the initial, radiation-damaged material. Theoretical models are discussed to rationalize the massive softening due to both radiation damage and subsequent anneal.
CLIMATIC CHANGE SINCE LITTLE ICE AGE RECORDED BY DUNDE ICE CAP

The climatic change since the Little Ice Age recorded in the Dunde Ice Cap is presentedin this paper. There have been three cold periods and three warm periods since 1400AD.Among them, the coldest one was in the 17th century. Many evidences verified the three coldand warm variations recorded in the Dundc Ice Cap. But it was found from the comparison between the Dunde Icc Cap climatic record and thewinter temperature record in Shanghai that there was a temporal dfference in climatic changebetween East China and West China. The general trend is that the cooling and warmingprocesses in West China were earlier than that in East China. In the Dunde Ice Cap, it isnow in an anomalous warm period, while it is not as warm as in Dunde Ice Cap recordaccording to the winter temperature in Shanghai. In addition to the possible cause of temporaldifference in climatic change between West China and East China, another possible cause isthat the greenhouse effect of CO2 may already be recognizable in the Dunde Ice Cap arealocated in Western China in land of the middle latitude.

ICIS 2009 PHOENIX UNDERSTANDING NET BENEFITS: A CITIZEN-BASED PERSPECTIVE ON EGOVERNMENT SUCCESS

eGovernment promises more efficient services and a more responsive government. Despite substantial investment, increasing failure rates have prompted critics to argue that policy makers are not achieving this vision. Surprisingly, there is very little research on what citizens define as important in eGovernment services and how aspects of government web sites affect that perception. The inclusion of the citizen perspective has largely been absent, denying a deeper understanding of the factors that drive usage. This research proposes an important and unique development of the D&M IS Success Model. By combining elements from public administration research and eGovernment success, this study constructs a comprehensive model of Net Benefits centred on the perspective of the citizen. The novel paradigm of Public Value is used to create a balanced success model, tailored for the public sector and is situated within the D&M IS Success Model. This research therefore aims to understand what citizens regard as important in the success of eGovernment services and what aspects of IT Quality affect eGovernment success.
Intrinsic toxicity evaluation of some newer insecticides against beetles of Holotrichia consanguinea Blanch. through adult vial test

A laboratory trial was conducted with seven insecticide molecules to identify the most efficacious compounds against beetles of Holotrichia consanguinea Blanch. during 2016 at RARI, Durgapura. The results of bioassay affirmed bifenthrin 10 EC as the most effective insecticide in terms of toxicity followed by fipronil + imidacloprid 80 WG, clothianidin 50 WDG, imidacloprid 17.8 SL, fipronil 80 WG, imidacloprid 600 FS and quinalphos 25 EC with LC50 values 0.08, 0.20, 0.76, 0.77, 1.44, 1.53 and 36.58 ppm, respectively. The relative toxicity of different insecticides on the basis of LC50 value to beetles by AVT demonstrated that bifenthrin 10 EC, fipronil + imidacloprid 80 WG, clothianidin 50 WDG, imidacloprid 17.8 SL, fipronil 80 WG and imidacloprid 600 FS were 457.25, 182.90, 48.14, 47.51, 25.40 and 23.91 times more toxic than quinalphos 25 EC.
Beyond Mean Entity Fairness: The Role of the Zone of Tolerance in Responding to Fairness Treatment

We propose that a zone of tolerance of fairness (ZOT) construct, which encompasses a boundary model, provides a deeper understanding of fairness processes. In two field experimental studies using scenario techniques, we manipulated fairness treatment in personnel selection settings and examined the role of a new ZOT measure in event fairness perceptions. Results from Study 1 (N = 222) demonstrated the psychometric properties of the ZOT measure, including reliability, and factorial and discriminant validity. We also found support for our hypothesis that the ZOT measure is a stronger predictor of perceived event fairness than a mean entity fairness measure. Furthermore, results from Study 2 (N = 108) replicated most of those from Study 1. We also demonstrated that individuals’ fairness perception is not a uniform entity but consists of four latent classes, determined by different levels of height and width of the ZOT measure. Class membership was predictive of perceived event fairness when treated unfair. Taken together, our findings suggest that the ZOT measure represents a promising supplementary instrument to the traditional approach targeting applicants’ mean entity fairness.

Effect of Synthesis Conditions of Asphaltene Sulfocationites on their Composition and Sorbtion Properties

Background/Objectives : The possibility of using asphaltenes from heavy crude oil to obtain sulfocationites with high total exchange capacity and sorption capacity with respect to cations Mg 2+ , Ca 2+ , Mn 2+ , Ni 2+ , Cu 2+ , Zn 2+ , and Fe 3+ has been shown. Methods/Statistical Analysis: The main method of asphaltene sulfocationite synthesis is the chemical interaction of asphaltene concentrates with sulfuric acid or oleum. However the main disadvantage of the obtained materials is that it is impossible to control grain size. Using the method of sulfonation of deasphalting residues (asphaltites) only powdered sulfocationites can be obtained. So, in order to produce this material in the form of grains and to increase their mechanical strength, a mixture of tarry residue with rubber crumb were used as the raw material. Findings : It was shown that the main advantage of asphaltene sulfocationites involves increased kinetic sorption capacity. During 1 hour asphaltene sulfocationites under static conditions adsorb from water solution at least 60% of magnesium and calcium, and 90% of heavy metals. In terms of these characteristics, asphaltene sulfocationites are superior to sulfonated coal, and come close to synthetic cation-exchange resin. However, at sufficiently high concentrations in the mixed salt solutions, the sorption capacity of asphaltene sulfocationites significantly reduces. As a result of the research performed we have shown that, on the basis of heavy oil asphaltenes, the efficient sulfocationites can be synthesized, which are characterized by a sorption capacity value with respect to different metals that stands at the same level as for conventional ion exchange materials. The cheapness of the raw materials and simplicity of asphaltene sulfocationite production technology mean they are promising for application in a variety of industrial and waste water treatment systems. Applications/Improvements : The main advantage of asphaltene sulfocationites is their increased kinetic sorption capacity.
Unified Analytical Solutions of Circular Tunnel Excavated in an Elastic-Brittle-Plastic Rock Mass considering Blast-Induced Damage and Dead Weight Loading

Stress and deformation around circular tunnel are crucial for optimizing the support system and evaluating the tunnel stability. The damage zone induced by blasting or mechanical excavation can dramatically influence the support design and methods because the self-weight of broken rock mass at the roof of the tunnel can exert a high pressure on the support system, leading to the support system instability due to the overload. This paper presents a new closed-form solution for analyzing the stress and deformation of deep circular tunnel excavated in elastic-brittle rock mass with the consideration of the rock gravity and damage zone by using the unified strength criterion. A new modified equilibrium equation in the fracture zone is used to determine the stress and the radius of fracture zone. The correctness of the solution is also verified by comparison with the numerical simulation results. The results illustrate that the rock gravity, damage zone radius, and intermediate principal stress have an extremely important influence on the ground response. The tunnel surface convergence and damage zone radius with the consideration of the gravity are obviously larger than those without consideration of the gravity. The rock gravity effect under the high intermediate principal stress gradually weakens, illustrating that the intermediate principal stress is beneficial to tunnel stability. Large deformation instability of the tunnel is dependent on the extension of damage zone. The larger the radius of damage zone, the larger both fracture range and tunnel surface deformation. The proposed solution in this study is novel and can be used to assess the ground convergence for different scenarios and to optimize the support system during the early design stage of the tunnel.
The Effect of Snakehead Fish (Channa striata) Extract on Inflammation Reaction of Skin Wound Tissue in Rattus novergicus Wistar Strain

Background: Snakehead fish has been associated with wound healing due to its high albumin content. Albumin can accelerate the inflammatory process so that tissue repair will be faster. Lack of albumin protein causes a person tend to experience prolonged wound healing. Purpose : This study aims to prove the effect of snakehead fish extract on the number of macrophages and blood vessels on the inflammatory reaction of skin wound tissue in rats. Methods : Laboratory experimental design with a total sample size of 27 male rats have undergone incisions, divided into 3 random groups: control group was given aquadest, treatment group 1was given aquadest and 50% extract of snakehead fish, and treatment group 2 was given 100% extract of snakehead fish. The rat’s skin wound tissues were taken on day 5 and observed under the microscope. The average number of macrophages and blood vessels on granulation tissue that formed at the base of the wound were counted and then performed data analysis. Result: In this study, we found a down wards trend in the average number of macrophages and blood vessels in treatment group 1 and treatment group 2. The control group and the treatment group 2 showed a significant difference, however, between the other groups did not show significant difference. Conclusion: There is a significant effect of giving 100% snakehead fish extract on decreased macrophages and blood vessels in the inflammatory reaction of skin wound tissue.
