HHS Public Access Author manuscript Author Manuscript Dentistry (Sunnyvale). Author manuscript; available in PMC 2017 March 24. Published in final edited form as: Dentistry (Sunnyvale). 2016 October ; 6(10): . doi:10.4172/2161-1122.1000397. Effects of a Novel Dental Gel on Enamel Surface Recovery from Acid Challenge Tracie Lam, Jessica Ho, Afarin Golabgir Anbarani, Lih-Huei Liaw, Thair Takesh, and Petra Wilder-Smith * Beckman Laser Institute, University of California, Irvine, CA, USA Author Manuscript Abstract Background—Objective was to evaluate the in vivo effects of a novel dental gel (Livionex gel R ) vs. a comparison dental gel on the surfaces of pre-eroded enamel chips. Methods—On days 1–5, after toothbrushing with dentifrice, nine subjects each wore 8 enamel chips mounted on a palatal appliance for 4 h. Enamel blocks were pre-demineralized daily. After 2 day washout, subjects repeated the protocol using fresh chips and the second toothpaste on days 8– 12. Samples were evaluated using electron microscopy. Author Manuscript Results—Ten standardized enamel surface photomicrographs/sample (total 1440 images) were evaluated for signs of erosion visually and on a scale of 0–3 by 1 evaluator. No significant differences were found between the 2 groups (p>0.32, 95% C.I.). Minimal surface erosion on approx. 15% of sample area was visible in both groups. Conclusion—The enamel surface appeared similar after usage of a test or control dentifrice. Based on this study, the test formulation did not affect enamel surface recovery from an erosive challenge. Practical implications—Dentifrices can contribute to maintaining a healthy enamel surface. An all-natural dental gel formulation with novel anti-plaque mechanism achieved similar recovery from acid challenge to enamel as a control gel. Keywords Erosion; De-mineralization; Re-mineralization; Scanning Electron Microscopy (SEM); Dental gel; Dentifrice Author Manuscript Introduction Dental erosion develops from chronic exposure to non-bacterial acids, resulting in mineral loss from the tooth surface and reduced surface micro-hardness. Clinical manifestations such as shallow lesions on smooth surfaces and cupping and flattening of cusps can develop even in early stages, which can lead to the exposure of coronal dentine.

Improving the travel time prediction accuracy for trucks based on historical GPS data

Route planning is an important part for companies that transport goods between different locations. To optimize the route planning, it is important that the travel time predictions come close to reality. A too tight schedule would lead to pressure to the driver, late fees and reputation damage, but a too loose schedule would result in wasted capacity. To predict the travel time, first a speed has to be assigned to each road in the digital map, after which the shortest path can be calculated. This research proposes a speed prediction model based on neural networks to predict the speed of each road such that the travel time prediction accuracy is improved. The neural network speed prediction model will be compared to the current speed prediction model, which is based on random forest. The speed prediction model first learns from preprocessed GPS data that is obtained from two different companies that operate with trucks. After relationships have been found between the driven speed and road properties (e.g. speed limit, road width, tunnel, etc.), the speed prediction model predicts a speed for each road in the digital map. Subsequently, the shortest path can be calculated from the first to the last GPS point of different routes. Then the predicted travel times from the shortest paths were compared to the real driven travel times. After comparison, it turned out that for both GPS data sets, the neural network speed prediction model did not outperform the travel time prediction accuracy in sMdAPE_TT of the random forest speed prediction model.

Health Insurance and Health Care Demand Pattern among Staff and Students of Selected Universities in Southwestern Nigeria

Background: Providing accessible and affordable healthcare services is a challenge for most developing economies including Nigeria. Currently, about 25-50% of all sick children and adults in Nigeria do not receive needed healthcare, while about 100 million live below the poverty line. The general poor state of the nation’s healthcare services, the excessive dependence and pressure on government for provision of health facilities have motivated the present study. This study was therefore designed to identify the determinants of healthcare demand pattern, with a focus on the role of health insurance among staff and students of selected universities in southwestern Nigeria. Methods: This study relies on cross-sectional data collected from four universities covering four states of Southwestern Nigeria namely: Olabisi Onabanjo University, University of Ibadan, Obafemi Awolowo University, and Ekiti State University. A three-stage sampling techniques was applied in Original Research Article Aremo and Ibukun; BJESBS, 20(2): 1-13, 2017; Article no.BJESBS. 31799 2 selecting 800 staff and students, while data were collected using structured questionnaire. The data was analyzed using SPSS v 20 and STATA v 12.1. Findings: Altogether, 47.6% of the respondents were staff while 52.4% were students. The overall proportion of insured staff and students were more than the uninsured staff and students. Also, the usage of the university’s healthcare center or hospital was observed to be higher (43.9%) than any other healthcare facility, although more than half of the participants (57.8%) that chose this provider are female. From the regression results, it was evident that health insurance and gender among other factors have positive and significant impact on the healthcare demand of staff and students of universities in Nigeria. Conclusion: Thus, policy makers should re-intensify the massive public awareness and education on the benefits of health insurance with the aim of improving demand for healthcare in Nigeria. Besides, for maximum efficiency, the public awareness should necessarily be gender-focused.
The Influence of Attitude, Product, Price, Place, and Promotion on Indonesian Consumers’ Purchase Intention towards Healthy Dessert

Results provided in this study can be considered by healthy dessert businesses in formulating a suitable marketing strategy that can support their business growth.
Soil moisture temporal stability and spatio‐temporal variability about a typical subalpine ecosystem in northwestern China

Knowledge of the spatial–temporal variability of soil water content is critical for water management and restoration of vegetation in semi‐arid areas. Using the temporal stability method, we investigated soil water relations and spatial–temporal variability of volumetric soil water content (VSWC) in the grassland–shrubland–forest transect at a typical semi‐arid subalpine ecosystem in the Qilian Mountains, northwestern China. The VSWC was measured on 48 occasions to a depth of 70 cm at 50 locations along a 240‐m transect during the 2016–2017 growing seasons. Results revealed that temporal variability in VSWC in the same soil layer in the three vegetation types and averaged across vegetation types tended to exhibit similar patterns of a decrease with increasing soil depth. Temporal stability in each vegetation type was stronger with an increase in soil depth. However, the results of temporal stability determined with standard deviation of relative difference (SDRD) disagreed with those based on the Spearman's rank correlation coefficient; the forest site had the highest Spearman rank correlation coefficient while the shrubland—the smallest SDRD in the 0–20 cm soil layer. Correlation analyses of VSWCs between two vegetation types indicated that soil water was related among all three vegetation types at the 0–20, and 0–70 cm soil layer, but in the 20–40 and 40–70 cm soil layers, significant correlation (p < .01) occurred only between adjacent vegetation types. In the upper soil layer (0–20 cm), soil water relations were mainly affected by surface runoff. In the lower soil layer (20–40 and 40–70 cm), soil water relations among the three vegetation types were highly complex, and probably resulting from a combination of root distribution and activity, interflow, and the impact of deep soil freeze–thaw dynamics. These results suggest that the factors affecting soil water are complex, and further research should address the relative importance of and interactions among different determining factors.
Statutory regulation of the security industry under pressure: the Brazilian case

ABSTRACT The literature has analysed the development and characteristics of the statutory regulation of the security industry in many parts of the world. However, researchers have neglected the political process inherent in the introduction or modification of regulation in developing countries. This article examines the process of formulating the regulation policy on the private security industry in Brazil between 2000 and 2018. This is acase study via process tracing approach based on the triangulation of data gathered from interviews, newspapers and official documents. The results show that this process is influenced by aprivate security policy community that has successfully resisted unwanted changes in regulatory policy, but has faced difficulties in making changes in statutory regulation in line with its interests. The article concludes by contrasting the Brazilian case with its British counterpart to suggest that political variables are key to understanding the statutory regulation of private security.
Study of Prevalence of Neonatal Septicaemia and Detection of Antibiotic Resistance in Besat Hospital in Iran

Background: Septicemia is one of the most important neonatal diseases which occurrs as a result of bacterial infection. The major criterion for its diagnosis is based on body fluid cultures specially blood culture. The aim of this study is to determine the prevalence of septicemia and also detection of isolated bacterial sensitivity to selected antibiotics in neonatal ward of Besat Hospital. Methods: This study is descriptive. Blood cultures were ordered for all hospitalized neonates. A questionnaire including clinical manifestations of septicemia such as fever, hyporeflexia, hypothermia, cyanosis, abdominal distention, loss of appetite and jaundice was filled out for every neonate clinically suspected of having septicemia. At last the collected data were analyzed by means of SPSS software and descriptive statistics. Results: This study included 700 specimen of blood cultures, 17.6% of the cases were suspected of having septicemia but %30 of them had positive blood cultures. The most common species isolated was coagulase negative staphylococci. As to sign and symptoms hyporeflexia, juandice, and anorexia were detected most frequently. Sensitivity of gram negative bacteria to ciprofloxacin was 100% & to cefotaxime 66.7%. Sensitivity of gram positive bacteria to cephalotin was 43%, while gram negative bacteria had highest resistance rate to ampicilin & cephalotine in 100% and gram positive bacteria to oxacilin in 68.6% & cotrimoxasol in 62.9% of the cases. In this study prevalence of septicemia in those having positive blood cultures was 30% with a mortality rate of 4.9%. Conclusion: This research shows that clinical manifestation is not enough for the diagnosis of septicemia and blood cultures should be considered necessary in suspected cases. Considering high resistance rate of isolated bacteria to ampicilin & cephalotin, culture and antibiogram can be of great value to select suitable antibiotic. Ciprofloxacin can be regarded as the drug of choice for gram negative bacteria. To reduce prevalence and mortality rates of septicemia, proper planning to confront microorganisms & nosocomial infections is necessary. Also appropriate and timely prescription of antibiotics by pediatricians can prevent bacterial resistance to antibiotics.

Enhancing Interactional Competence in EMI

This chapter shows the role of in-service EMI teacher reflective practices by showcasing the use of self- and peer-reflection on classroom interaction by two EMI lecturers at UAM. Based on previous models for the analysis of classroom interactional competence at tertiary level and in CLIL contexts, the authors apply the video technology of VEO, which helps teachers to gather and interpret their own teaching evidence and that of others. This interpretation is based on a tagging system that allows EMI teachers to identify types of interactional patterns, their frequency, and their effect in their observation of their own video-recorded lessons. These reflections are then followed by their trainers' own reflections on these practices, which can be added as comments in the VEO tool. In addition, students' perceptions on these practices are analysed through their answers to a questionnaire administered right after each lesson.
Study of the Influence of Helical Milling Parameters on the Quality of Holes in the UNS R56400 Alloy

Helical milling has been positioned as an alternative to conventional drilling, where the advantages it offers make it very attractive for use on difficult-to-machine alloys such as the titanium alloy UNS R56400. However, the correlation between the indicator of hole quality and the kinematic parameters has rarely been studied. The kinematics are what bring most advantages and that is why it is necessary to know their influence. In this aspect, there are different focuses of problems associated with the complexity of the process kinematics, which makes it necessary to undertake a deeper analysis of the process and to carry out a preliminary study. To address this problem, a DOE (Design of Experiments) is proposed to identify the sensitivity and the main trends of the properties that define the quality holes with respect to the kinematic parameters. At the same time, a nomenclature is proposed to unify and avoid misinterpretations. This study has allowed us to obtain conclusive results that offer very relevant information for future research

Late-Life Living Arrangments and Intergenerational Ties in Egypt: Elderly Socio-Economic Conditions from Labor Market Surveys

The aim of this paper is to analyze dynamics in the late-life living arrangements and changes in socio-economic and health condition of the elderly in Egypt in recent years. Research questions refer to the determinants of ageing in Egypt and to the disparities existing and emerging at the gender and place of residence levels. Our focus is on the role intergenerational ties and transfers, both public and within the family, have in alleviating the precarious situations of older persons. This paper intends to help fill the gap in the study of this topic, which is still understudied in the country as well as in the MENA area more generally. The research refers to individual data from all three rounds of the Egypt Labor Market Panel Surveys (ELMPS), carried out in 1998, 2006, and 2012.
The role of innovation narratives in accomplishing organizational ambidexterity

Persistent tensions arising from the exploration–exploitation paradox continuously threaten the accomplishment of organizational ambidexterity. Structural, contextual, and sequential solutions designed to alleviate these tensions dominate the ambidexterity literature. None of these adequately explains how top executives implement tension-alleviating managerial initiatives or how they respond in real time to tension-induced organizational perturbations. In this article, through analysis of top management team speeches at Procter & Gamble over a 15-year period, we show how the construction and communication of four innovation narratives—contextualizing, mutualizing, dramatizing, and focalizing—reduced tensions and enhanced organizational ambidexterity. We demonstrate the importance of top management team reflexivity in devising and communicating performative narratives, illustrate the polyphonic model of narrative strategizing, and present a cyclical model suggesting that the accomplishment of organizational ambidexterity is an ongoing dynamic process.
Patient Safety Culture as Viewed by Medical and Diagnostic Staff of Selected Tehran Hospitals, Iran

Background: Today, patient safety is an important issue in providing hospital services. Any failure in this area can cause undesirable consequences. Objective: The present study evaluated the status of patient safety culture in Educational Hospitals of Tehran, Iran. Methods: This cross-sectional study surveyed 205 therapeutic and diagnostic personnel of three Tehran hospitals selected using the clustered method; samples were collected in a randomized manner. To examine patient safety culture, the standard questionnaire of patient safety culture with 12 dimensions was used. Data was analyzed using SPSS software. Results: In the 12 dimensions of patient safety culture, exchange of data, expectations, and organization management had the lowest means of 3.28 (±0.87), and 3.32 (±0.74) among the various aspects of patient safety culture. Additionally, the two dimensions of teamwork within the organization’s units and frequency of reporting events with means of 3.71 (±0.79) and 3.73 (±0.7) had the highest means among the studied 12 dimensions of patient safety culture. The total mean of patient safety culture in the studied hospitals was 3.5 (±0.5). Conclusion: Increasing the attention paid to patient safety culture will lead to the development and progress of hospitals in the country and will guide them toward becoming patient-friendly hospitals. Those dimensions which had low mean values in this study should be paid more attention so as to promote and protect them.
Drugs on the internet: Mapping the terrain of engagement with darknet drug cryptomarkets in New Zealand

This thesis explores the experiences of New Zealanders who order illicit drugs from cryptomarkets, with particular attention to their perspectives on New Zealand’s conventional illicit drug market, the negatives and positives of drug cryptomarkets, and their notable insights and features. Internationally, research on engagement with drug cryptomarkets is emergent. However, peer-reviewed research on New Zealand drug cryptomarket users remains absent. This thesis attempts to begin to fill this gap, exploring the experiences and viewpoints of New Zealand drug cryptomarket users within the context of existing international literature. The study utilised qualitative, semi-structured interviews with 12 New Zealanders who have accessed drug cryptomarkets. The data from the interviews were interpreted through thematic analysis using constructivist grounded theory. The research found that the constraints of New Zealand’s conventional drug market push some drug consumers to use cryptomarkets to access illicit drugs. Although drug cryptomarkets have various pull factors that attract participants to them, they also have negative aspects which influence participants’ choices and behaviours when accessing cryptomarkets. The findings that are presented give voice to the lived experiences of New Zealanders who access drug cryptomarkets, extend scholarly knowledge of cryptomarket users, and highlight further avenues for research.
