 Abstract

Objective: The purpose of this in vitro study was to evaluate the effect of polyacrylic acid as dentin priming agent on tensile bond strength of self adhesive resin cements to dentin. Materials and method: Extracted premolar which were selected for the study were mounted in self cure acrylic which were trimmed buccally with the help of diamond disc under running water and was smoothened with abrasive paper (180 grit) for flat surface. Zirconium block with 3mm diameter and 5mm height with through and through hole of diameter were designed and fabricated with the help of CAD CAM milling machine. Teeth were divided into three groups according to dentin surface treatments 1) Group A- Control group (without dentin pre-treatment ) 2) Group B- 11.5% polyacrylic acid treated group 3) Group C- 25% polyacrylic acid treated group. The zirconium blocks were bonded to dentin surfaces with self adhesive resin cements which were tested for tensile bond strength. All the data was statistically analyzed. The comparison between three groups was done by one-way ANOVA test for continuous data and followed by post-hoc multiple comparison test The de-bonded surface were evaluated with scanning electron microscope for assessing mode of failure. Results: There was a significant difference between the groups and on applying post hoc the difference was found between group C with the group B and group A. The mean tensile bond strength of group C was found to be statistically significantly higher statistically than that of group B and group C. (p<0.05). Conclusion: Within the limitations of this in vitro study, group C showed higher tensile bond strength when compared to group A and group B. Dentin pretreatment with group C increased the bond strength of self adhesive resin cement.

 Abstract

The purpose of this article is to generalized the result of W. Sintunavarat and P. Kumam [4]. We also give an example in support of our theorem for which result of W. Sintunavarat and P. Kumam [4] is not true. Moreover we establish the existence and convergence theorems of coupled best proximity points in metric spaces, we apply this results in a uniformly convex Banach space.

 Abstract

Novel coronavirus disease (nCOVID-19) is the most challenging problem for the world. The disease is caused by severe acute respiratory syndrome coronavirus-2 (SARS-COV-2), leading to high morbidity and mortality worldwide. The study reveals that infected patients exhibit distinct radiographic visual characteristics along with fever, dry cough, fatigue, dyspnea, etc. Chest X-Ray (CXR) is one of the important, non-invasive clinical adjuncts that play an essential role in the detection of such visual responses associated with SARS-COV-2 infection. However, the limited availability of expert radiologists to interpret the CXR images and subtle appearance of disease radiographic responses remains the biggest bottlenecks in manual diagnosis. In this study, we present an automatic COVID screening (ACoS) system that uses radiomic texture descriptors extracted from CXR images to identify the normal, suspected, and nCOVID-19 infected patients. The proposed system uses two-phase classification approach (normal vs. abnormal and nCOVID-19 vs. pneumonia) using Random Forest classification algorithms. The detection of severe acute respiratory syndrome coronavirus 2 (SARS CoV-2), which is responsible for coronavirus disease 2019 (COVID-19), using chest X-ray images has life-saving importance for both patients and doctors. In addition, in countries that are unable to purchase laboratory kits for testing, this becomes even more vital. In this work, we aimed to present the use of machine learning for the high-accuracy detection of COVID-19 using chest X-ray images.

 Abstract

The study aims at describing the underlying mechanisms within the relationship between nursing turnover and quality of care of patients. The target of the study was to seek out however turnover in nursing units affects processes among key work teams and the way the impact of those processes affects outcomes of patients. Additionally T this study was to look at however nursing unit turnover affects key workgroup processes and the way these processes mediate the impact of nursing turnover on patient outcomes. We tend to additionally notice suggestive proof that turnover ends up in lower quality in alternative dimensions and will increase mortality. Associate in nursing implication of our mortality results is that turnover is also a mechanism for the procyclicality of mortality rates. Additionally this paper Understanding the determinants of patient mortality will cause the event of ways that scale back mortality and stop unnecessary death.
