Color assessment in dental prostheses: the use of smartphones as process tools

Accurate color selection of direct or indirect dental restorations is a subjective task. Mobile phones are tools that may minimize color assessment errors. Objective: To use photographs taken with smartphones to guide the dental surgeon in choosing the right color in oral rehabilitation. Material and Methods: A tooth was photographed for color assessment and the VITA Toothguide 3D-MASTER® shade guide was used. Photographs were submitted to an image editing software for full saturation removal. Images of the tooth and scale in black and white were compared. Results: This method allowed to select the tooth’s value, which is considered the most subjective dimension in color choice. Conclusion: Although it is an auxiliary and complementary method to traditional methods, smartphones are tools capable of reducing the range of color possibilities and minimizing possible failures.KeywordsColor; Photograph; Smartphone.
Influence of Seed Priming with ZnSO and CuSO on Germination

Abiotic stress is an important environmental problem limiting crop growth and productivity. Micronutrients have ability to overcome stress up to some extent. This study was carried out to investigate the effects of priming with micronutrients (Zn and Cu) on Brassica rapa grown under NaCl stress. Seeds were primed with 100 and 200 ppm ZnSO and CuSO and then treated with different concentrations (0 mM, 60 mM, 4 4 90 mM, 120 mM) of NaCl. Effect of NaCl, ZnSO and CuSO were observed on germination, seedling growth 4 4 separately. It was observed that germination and different seedling growth parameters viz. shoot length, root length, fresh and dry biomass were decreased under different concentrations of NaCl (without treatment of ZnSO and CuSO ). It was also observed that treatment with different doses of ZnSO and CuSO exhibited 4 4 4 4 increase in germination and seedling growth in both salinity levels as well as in non-saline conditions.
Corporate Diversification and Corporate Social Performance in Indonesia

The relationship between corporate diversification and corporate social performance (CSP) is under-investigated, especially in emerging countries. This study examines the relationship between corporate diversification and CSP in Indonesia setting. Occurrence disclosure analysis has been applied to measure CSP based on 80 indicators of the Global Report Initiative (GRI). This study used multiple regressions with one-year lag dependent variables as the data analysis. The results show that the related diversification is negatively and significantly related to CSP, while, the unrelated diversification reveals a positive relationship with CSP. Besides that, unrelated diversification more correlated to CSP rather than related diversification. Furthermore, international diversification has a positive and significant relationship with CSP. Therefore, this study found that corporate diversification is a significant antecedent of CSP.JEL Classification: L25, M14

Schema mappings have been extensively studied in the context of data exchange and data integration, where they have turned out to be the right level of abstraction for formalizing data inter-operability tasks. Up to now and for the mostion for formalizing data inter-operability tasks. Up to now and for the most part, schema mappings have been studied as static objects, in the sense that each time the focus has been on a single schema mapping of interest or, in the case of composition, on a pair of schema mappings of interest. In this paper, we adopt a dynamic viewpoint and embark on a study of sequences of schema mappings and of the limiting behavior of such sequences. To this effect, we first introduce a natural notion of distance on sets of finite target instances that expresses how “close” two sets of target instances are as regards the certain answers of conjunctive queries on these sets. Using this notion of distance, we investigate pointwise limits and This article is part of the Topical Collection on Special Issue on Database Theory Emanuel Sallinger emanuel.sallinger@cs.ox. ac.uk Phokion G.

We obtain a number of results about the limits of sequences of GAV schema mappings and the limits of sequences of LAV schema mappings that reveal striking differences between these two classes of schema mappings. We also consider the completion of the metric space of sets of target instances and obtain concrete representations of limits of sequences of schema mappings in terms of generalized schema mappings, that is, schema mappings with infinite target instances as solutions to (finite) source
Entrepreneurial Orientation, Total Quality Management, Competitive Intensity, and Performance of SMEs: A Resource-Based Approach

Drawing upon resource-based theory, as well as contingency theory, this study examined the role of competitive intensity in moderating the relationships between entrepreneurial orientation, total quality management, and SME performance. Using a stratified random sampling, 714 self-administered questionnaires were distributed to owner‐managers of SMEs operating in Kano and Kaduna in the north-west geopolitical zone of Nigeria. Of the 714 questionnaires distributed, 440 unusable questionnaires with 62 percent responses were returned and further analysed. The hypotheses were tested using Partial Least Squares Structural Equation Modeling (PLS-SEM). Results supported the hypothesised main effects of entrepreneurial orientation, and total quality management, on SME performance. Also, the competitive intensity was found to moderate the relationships between entrepreneurial orientation and SME performance. On the contrary, no significant interaction effect was found between total quality management and competitive intensity. The theoretical contribution of the present study lies in its use of competitive intensity as a moderator of the relationships between entrepreneurial orientation, total quality management, and SME performance.
The Effect of Extension with Audio Visual Method on The Improvement of Knowledge Levels and Attitude of The Use of Borax In The Making of Gendar Crackers in Family Households

Background: Food is one of the basic important of human needs. Since the mid-20th century, the role of food additives, particularly preservatives are becoming increasingly important in line with advances in production technology of synthetic BTP (food additives). The use of BTP often adverse effects on health. Some of the causes were the use of non-organic materials due to economic reasons. The lower public's knowledge about quality and safety of food led to rampant cases of food poisoning. This compounded with various kinds of food additives (BTP) are derived from chemical products and its derivatives. Cracker was one of snack that much-loved by the majority of Indonesian people. On making of Crackers both the traditional and the modern are often added borax as a food additive that was felt to be more savory crackers and crunchy. This research aimed to examine the influence of counseling with audio-visual method on the improvement of knowledge and attitude of use borax on making gendar crackers family households in Kategan, Patalan, Jetis, Bantul, Special Region of Yogyakarta Province. Methods: This research used quasi experiment type with the design of one group pretest - posttest. The samples were housewives in the Kategan, Patalan, Jetis, Bantul. Results: There was a difference of housewife’s knowledge in Kategan on the use of borax on making gendar crackers between before and after counseling with audio-visual methods which seen by a mean value of 6.64 pre-test and 6.92 for post-test average with -1.238 as mean difference. Based on the results of Wilcoxon test obtained p-value of 0.216 (H0 was accepted). While the mean, obtained on the attitude of the pre-test of 10.28 and the mean of post-test of 11.19 with a mean difference of -2.018. The p-value was 0.044 (H0 was rejected). Conclusion: There was no effect of counseling with the use of audio-visual methods in use of borax on making gendar crackers on the knowledge. Whereas there was influence of counseling with the use of audio-visual methods in the use of borax on making gendar crackers on the attitude. Keywords: knowledge, attitudes, audio visual, borax
Saturation effect and anti-windup schemes for time-delay systems

Title: Saturation effect and anti-windup schemes for time-delay systems In the present dissertation thesis, an analysis of a class of time-delay controllers subject to astatic behaviour associated with the so-called windup effect in control loops with saturating actuators is conducted using both analytical and spectral approach. An observer-like anti-windup scheme for the class of controllers is proposed with an emphasis on easy subsequent tuning. The effort to simplification leads to a functional feedback deployment which may involve time-delay elements in it. This approach beneficially reduces the anti-windup tuning task to a finite-spectrum assignment. The tuning of the proposed anti-windup scheme is done by minimization of the control error integral criterion with respect to a single tuning parameter. At first, the proposed approach is applied to loworder models. Then, a generalized state feedback parametrization based on Ackermann formula applied to anisochronic observer design is deployed to a high-order heat-transfer model. As a complementary topic, the saturation effect to the performance of the closed loop with the feedback inverse shaper as a oscillatory modes compensator is studied. The study concludes with experimental validation using a laboratory set-up and a simulation model.
Transiting to Student-Centered Learning in Kazakhstan: Undergraduate Student Experiences

Karaganda State Medical University has been transitioning and practicing active methods of teaching and learning since 2011. Faculty members are encouraged to lead their courses with diverse activities designed to increase student learning. Unfortunately, there is limited evidence regarding the extent of faculty members who evaluate their own courses. With this in mind, this paper aims to explore and share undergraduate students’ learning experiences and the teaching of Philosophy at a medical university. The course, which ran from February to May in 2017, was taught in English. The class was divided into four groups of international students and two groups of local students. Using a qualitative method, a total of 63 students responded to open ended questions. Additionally, 23 students, comprising four students from each group, were engaged in focus group discussions. Students’ participation and performance in classes were also observed over the period of the course. This presentation will focus on the outcomes of the study within the wider context of the discussion about ways in which Kazakhstani universities are opening up to educational changes in the context of globalization. Feedback from other conference participants is most welcome.
Gravity and Magnetic Modeling Sergipano Belt, Brazil: Tectonic Control and Crustal Thickness of the Basement Adjacent to the Sergipe-Alagoas Basin

This work used gravimetric and magnetic data to investigate the Sergipano Belt that occupies the Southern Borborema Province, Brazil. The main objective was to interpret tectonic relationships between the geological domains, crustal lateral variation of the physical properties and the behavior of the Moho relief. The gravity and magnetic inversion was performed to determine the physical properties magnetic susceptibility and density contrast to delineate the geometry of the true source. The regional gravity anomaly was used to obtain solutions depth of the interface crust-mantle in which it was necessary to know the initial model of the crustal thickness and density contrast. The geophysical measures was used to delineate the initially crustal thickness and compared to the results based on a compilation of data published in the literature mainly derived from seismic database such as deep seismic refraction experiments. These magnetic sources have signals with different amplitudes that originate from different geometric sources, situated at different depths and with different magnetic properties. As to the crustal thickness results, we found that the southern region of the Sergipano Belt has a crustal (34-35 km) and mantle uplift, mainly in the Girau do Ponciano Dome. The Rio Coruripe domain as well as the PEAL Terrain has a thicker crust (38-40 km), with magnetic and gravimetric sources that reach from 15 to 20 km deep marked in sections.
Phytochemical analysis, in vitro antioxidant activity and in vivo anti-inflammatory and analgesic activities of selected medicinal plants of Nepal

Nepalese medicinal plants were selected to study phytochemical presence, antioxidant, anti-inflammatory and analgesic activity of plants. Extraction was carried out by double maceration by ethanol and water. Phytochemical screening was performed by standard methods. Total phenol content was determined by Folin Ciocalteu method, flavonoid content was determined by aluminium chloride colorimetric method. The antioxidant activity was tested by DPPH free radical scavenging assay. In Vivo anti-inflammatory and analgesic activity was performed by carrageenan induced rat hind paw edema and hot plate methods respectively. The phytochemical analysis revealed the presence of flavonoids, alkaloids, tannins, saponins, phenols, terpenoids, glycosides and carbohydrates. The ethanolic and aqueous extract of Viscum album showed total phenols content, total flavonoids content and has significant antioxidant activity. Similarly, the aqueous extract of Viscum album has dose dependent analgesic activity. Thus, medicinal plants possess different compounds with valuable antioxidant properties which can contribute to the development of modern medicines.
Are MOOCs in Blended Learning More Effective than Traditional Classrooms for Undergraduate Learners?

Massive open online courses (MOOCs) have become one of the most prominent trends in higher education. In contrast to a traditional classroom where knowledge is delivered through face-to-face interaction, MOOCs offer open-access, video-based instructional content, and forums which are released through an online platform to unlimited number of learners. Despite impressive notable features, their effectiveness has yet to be proven. Intrigued with this issue, the objective of this study is to examine the effectiveness of learning via MOOCs in blended learning and traditional classrooms among undergraduate learners. An experimental study which employed non-equivalent pre-test and post-test control group design among two hundred and five undergraduate accounting students was conducted in one of the universities in Malaysia. The students were divided into two groups; experimental and control. The experimental group was taught via MOOCs in blended learning, while the control group was taught in traditional classrooms. The results of paired sample T-test indicated that there were significant differences in academic achievements between the pre-test and post-test groups (experimental and control groups). The magnitude of effect of the former was higher than the latter. The results of MANOVA indicated that there were significant differences in academic achievements between groups in post-test, but not in the pre-test. Hence, MOOCs are more likely to be more effective than traditional classroom in teaching and learning today's generation which consists of digital savvy natives. The discoveries provide significant insights for educational fraternities on technological and pedagogical aspects of how teaching and learning can best be delivered and acquired.
Investigating the Efficiency of GCC Banking Sector: An Empirical Comparison of Islamic and Conventional Banks

We examine and compare the performance of 63 (21 Islamic and 42 conventional) GCC banks at two tiers, covering the period of 2010–2016. In the first tier, an industry-level analysis is conducted of each country, followed by an individual bank-level analysis in the second tier. Deposits, assets, and capital are taken as inputs to measure the outputs using data envelopment analysis techniques. At the industry level, we find that Islamic banking is at par with-if not better than-conventional banking in all terms of efficiency. Particularly, banking in Bahrain and KSA is among the best, whereas there is no scope for improvement in the UAE’s banking industry. This low performance could be attributed to a lack of standardization in products and schemes as well as the level of prudence in decision-making, governance, and operations. At the bank level, many Islamic banks perform even better than conventional banks. Most studies on GCC and MENA focus on the determinants and indicators of development and the banking industry growth in general. Uniquely, we further examine GCC banking performance at the individual bank level by incorporating the latest available data.
Dental Caries among Sudanese Children with BetaThalassemia Major

Background: The aim of this study was to determine the association between β-thalassemia major and dental caries among a sample of Sudanese children compared to healthy control children. Methods: This study was carried out in 54 children with β-thalassemia major aged (4-16) years old compared to 54 healthy control group matched with age and gender in Khartoum state. Dental caries was examined using (dmft, DMFT) index by WHO for primary and permanent dentition. Statistical analysis was done using the statically package for social science (SPSS) version 20. The 95% confidence interval for the association between variables were estimated and compared using Chi-square test. P value ≤ 0.05 was considered statically significant. Results: The mean dmft and DMFT in β-thalassemia major was double the value in the healthy control group (4.4 vs. 2.3 and 1.5 vs. 0.7) respectively. Significant difference was recorded between the βthalassemia major group and healthy group in DMFT (p≤0.038) and dmft (p≤0.005). No statically significant difference between boys and girls among children with β-thalassemia major. Conclusion: Children with β-thalassemia major experience more dental caries compared to the normal healthy control group. Perception of the situation of βthalassemia children should contribute for the planning of dental services that can help in reduction of dental caries incidence and avoid future dental problems.

Why Do We Fall for Persuasion? The Moderating Role of Trait Self-Control in Nudging Interventions

Man’s capacity to exert self-control and adapt to demands of group life marks a crucial component of civil society and life as we know today (Freud, 1930). Many studies summarize the definition of self-control as the capacity to consciously regulate one’s behaviour in order to be in line with their environment, fostering social desirability and goal achievement, ultimately enabling individuals to live happy, successful, and healthy lives (Baumeister et al, 1998; Baumeister, Vohs, & Tice, 2007; Vohs & Faber, 2007; de Ridder et al, 2012). Another term for self-control is self-regulation, which contains a similar meaning. Both terms will be used interchangeably within this research.
Sorption of Aspirin from Aqueous Solutions using Rice Husk as Low Cost Sorbent

The Rice Husk (RH) was used as low cost sorbent for the removal of aspirin by sorption from aqueous solution. The RH was characterized by using the point of zero charge (pHpzc), Boehm titration and Fourier transform infrared spectroscopy (FTIR). Batch sorption experiments are intended to identify the adsorption isotherms of aspirin on the RH. The experimental data were fitted to the Langmuir and Freundlich isotherms. The Sum of the Squares of the Errors (SSE) and the correlation coefficient R between the calculated and the experimental data by nonlinear regressive analysis were used. The Langmuir model better described the isotherm data with the maximum Langmuir monolayer adsorption capacity was 47.03 mg g at pH 2. As a conclusion, RH could be one of the low cost and environmentally friendly sorbent.
