(M=Ba or Mg) materials prepared using the combustion synthesis method were annealed either in an air or carbon atmosphere. The materials were characterized using X-ray diffraction, scanning electron microscopy, diffuse reflectance spectra, electrochemical impedance spectroscopy, and photoluminescence (PL) measurements. Their photocatalytic activity was evaluated for the dye degradation and hydrogen evolution. Methylene blue (15 ppm) was completely degraded using the air-annealed barium aluminate after 90 min, while a maximum hydrogen generation rate of

Published: March 2020

In the Fizeau imaging interferometer testbed we recently built, the optical path difference (OPD; i.e., piston error) among three sub-telescopes should be corrected for phased imaging to enhance the spatial resolution. This study presents the detection of the OPD via a dispersed fringe sensor (DFS) method and its closed-loop control. The retrieval of the OPD from a dispersed fringe map is a fast-Fourier-transform-based DFS method, which indicates in theory that the OPD has a linear relationship with the displacement of the secondary peaks in the Fourier spectrum of the dispersed fringe map. Then the design and alignment of the OPD detection module are presented, as well as the OPD compensation module with a two-level motion stage. A unique benefit of the fast-Fourier-transform-based DFS is high time efficiency for closed-loop control; for a window of

Published: March 2020

Objective: The Oral Health Impact Profile-14 (OHIP- 14) and the Geriatric/General Oral Health Assessment Index (GOHAI) have never been compared to a group of the same subjects in the Brazilian population. The aim of the study was to compare the OHIP-14 and GOHAI measures. Material and Methods: 129 independently living people over the age of 60 were included in the study. The GOHAI and OHIP-14 measures were used. Other variables were included: age, gender, education, number of missing teeth, annual household income and frequency of dentist visits. Results: The mean age of respondents was 65 years. The internal reliability (Cronbach’s alpha) showed a high internal consistency for both measures. Spearman’s rank correlation coefficient between the GOHAI and OHIP-14 scores was 0.73. Using the additive method of creating scores, none of the respondents had the GOHAI score of zero, indicating no impact from oral conditions, while 9.3% of them had an OHIP-14 score of zero. Dental status, age, gendler and frequency of dental visit were significantly associated with the results ofthe GOHAI and the OHIP-14 (Kruskal–Wallis test, Mann–Whitney U test). Conclusions: There was a strong correlation between the GOHAI and the OHIP- 14. Both instruments demonstrated good discriminant properties and helped capture the respondents’ oral health problems.KEYWORDSBrazil; Older adult; GOHAI; Oral health-related quality of life.
Effect of immediate dentin sealing, bonding technique, and restorative material on the bond strength of indirect restorations
Authors: Sag Bilal Utku , Ozel Bektas Ozden 
Published: March 2020

Objective: The objective of this study was to evaluate the effect of immediate dentin sealing, bonding technique, and restorative material on the dentin bond strength of an indirect composite (Solidex) and a resin nanoceramic CAD/CAM block (LAVA Ultimate). Material and Methods: A total of 120 periodontally extracted human molar teeth were abraded horizontally and divided into two groups according to dentin sealing procedures (delayed dentin sealing [DDS] and immediate dentin sealing [IDS]). Next, all teeth were attached to a simulated pulpal pressure mechanism. The specimens were removed from the mechanism after a week. Teeth were subdivided into three groups based on the bonding technique and the type of cement used (Acid-etching + Single Bond Universal + RelyX Ultimate, Single Bond Universal + RelyX Ultimate, RelyX Unicem). Each subgroup was further divided into 2 subgroups according to the type of restorative material used (Solidex [n=10], Lava Ultimate CAD/CAM restorative material [n=10]).. Sixty cylindrical samples prepared using both the restorative materials were bonded to the tooth surface according to their group’s bonding procedures. All specimens were embedded in chemically cured acrylic resin for shear bond strength test. The shear bond strength (SBS) of the specimens was determined by a universal testing machine with a headspeed of 0.5 mm/min. Results: Three-way ANOVA, independent-sample t test and post hoc Tukey comparison tests (?=0.05) were performed on all data. There were significant differences between the groups. It was found that IDS process significantly increased bond strength in all groups. When dentin bond strengths of tested luting cements were compared, the highest bond strength values were recorded in groups in which the specimens were luted with RelyX Ultimate cement using etch-and-rinse technique. The lowest bond strength values were obtained from groups that used RelyX Unicem as the luting cement. Conclusions: IDS improves bond strength of indirect restorations. Moreover, bonding techniques may have critical effects on the dentin bond strength of indirect restorative materials. The cements’ specific affinity levels to both restorative materials and dentin could be considered as the reason of the situation.KEYWORDSIDS; Luting cement; Shear bond strength; Resin nanoceramic; CAD/CAM.

Published: March 2020

Sometimes the rivalry between shareholders and management is an indication of the level of entrenchment within the corporate environment. Managers are believed to routinely manipulate earnings in order to mislead shareholders about their company's actual economic outlook or performance. As a result, the study investigated the impact of managerial entrenchment, firm characteristics and earnings management of conglomerate companies in Nigeria. Employing the ex-post facto research design, the data was gathered from secondary source of the 6 listed conglomerate companies for the 11-year period running (2008-2018). The study used discretionary accruals a proxy for earnings management and to calculate discretionary accruals, the study used modified Jones model. The result showed that management entrenchment and firm characteristics have Impact on multinational firms ' earnings management in Nigeria. Specifically, from the conglomerate’s entrenchment proxies, CEO’s tenure has a positive and significant impact on earnings management (coff. =1.062821, p-value =0.0367) and management entrenchment as measured by CEO’s shareholding has a negative and insignificant effect on earnings management (coff. =-6252391, p-value = 0.4090) while firm size, profitability and leverage indicated a significant and positive impact on earnings management (coff, = 0.124587, p-value = 0.0000; coff. = 0.006647, p-value = 0.0431 and coff. = 0.032065, p-value = 0.0000). The study therefore recommended among others that management should reduce the debt in their capital structure in order to improve their companies’ value and their capital structure should be majorly financed by equity rather than debt and reduce CEOs tenure to minimise earnings management practices.
The Accrual Accounting Principle and its Implications for Portuguese Tax Courts Decisions
Authors: Taborda Daniel , Sousa João 
Published: March 2020

Abstract
To the best of our knowledge, this is the first paper focusing on the interpretations issued by different Portuguese courts concerning the application of the accrual principle established in the Corporate Income Tax Code.
This paper uses a database of the Portuguese tax courts’ decisions and employs a case law-based research methodology to address the following question: under which circumstances the principle of justice may affect the strict application of the accrual principle? After collecting twenty-four legal decisions related to the application of the accrual principle outlined in tax law, this paper summarises eleven, grouping them according to the different issues under dispute. This analysis also includes the confrontation of the assumptions used by the tax authority and the claims of the taxpayers, identifying and discussing the legal arguments to override the strict application of the accrual principle.
The main conclusion is that Portuguese courts may summon the principle of justice in taxation when taxpayers violate the accrual principle, in order to prevent unfair corrections to taxable income performed in tax audits. This paper found that the tax authority typically demands a rigid use of the accrual principle while the taxpayers often argue for a more flexible application. This last perspective has been adopted by the tax courts in certain circumstances, in particular when taxable income transfer was not motivated by tax avoidance.
Minimum action solutions of nonhomogeneous Schrödinger equations
Authors: Ahmad Bashir , Alsaedi Ahmed 
Published: March 2020

Abstract
In this paper, we are concerned with the qualitative analysis of solutions to a general class of nonlinear Schrödinger equations with lack of compactness. The problem is driven by a nonhomogeneous differential operator with unbalanced growth, which was introduced by Azzollini [1]. The reaction is the sum of a nonautonomous power-type nonlinearity with subcritical growth and an indefinite potential. Our main result establishes the existence of at least one nontrivial solution in the case of low perturbations. The proof combines variational methods, analytic tools, and energy estimates.
The effects of five public information campaigns: The role of interpersonal communication
Authors: Solovei Adriana , van den Putte Bas 
Published: March 2020

Abstract
For five Dutch public information campaigns, this study assessed whether interpersonal communication mediated the effects of exposure (to TV, radio, or online banners) on five persuasive outcomes: awareness, knowledge, attitude, intention, and self-reported behavior. Structural equation modeling was used to test 23 models relating exposure to one of these outcome variables. Few direct effects of media exposure were found (for online banners, TV, and radio in, respectively, one, four, and seven of the 23 models). In contrast, results revealed that interpersonal communication had direct effects on the outcomes in 17 of the 23 models. Moreover, indirect effects of media exposure via interpersonal communication were found for online banner, TV, and radio exposure in, respectively, eight, nine, and ten models. These results indicate that interpersonal communication plays an important role in explaining media exposure persuasive effects and should be taken into account in the development and evaluation of public information campaigns.
Liability for the Fact of Autonomous Artificial Intelligence Agents. Things, Agencies and Legal Actors
Authors: Monterossi Michael W. 
Published: March 2020

AbstractEuropean Union institutions are currently studying the regulatory intervention needed to face liability problems solicited by the use of autonomous artificial agents, whose unforeseeable actions may result in damage for their users or third parties. This paper intends to analyze some of the solutions proposed, by putting in relation – also from a historical perspective – the possibility of widening producers’ or users’ strict liability for actions by artificial agents even when they are not fully predictable and that of extending the status of legal actor to some of these artificial agents, so as to attribute the damaging fact directly to them.

Abstract

Background
In the present era, obesity is increasing rapidly, and high dietary intake of lipid could be a noteworthy risk factor for the occasion of obesity, as well as nonalcoholic fatty liver disease, which is the independent risk factor for type 2 diabetes and cardiovascular disease. For a long time, high-lipid diet (HLD) in “fast food” is turning into part of our everyday life. So, we were interested in fulfilling the paucity of studies by means of preliminary evaluation of these three alternative doses of HLD on a rat model and elucidating the possible mechanism of these effects and divulging the most alarming dose.

Methods
Thirty-two rats were taken, and of these, 24 were fed with HLD in three distinctive compositions of edible coconut oil and vanaspati ghee in a ratio of 2:3, 3:2 and 1:1 (n = 8), orally through gavage at a dose of 10 mL/kg body weight for a period of 28 days, whereas the other eight were selected to comprise the control group.

Results
After completion of the experiment, followed by analysis of data it was revealed that hyperlipidemia with increased liver and cardiac marker enzymes, are associated with hepatocellular injury and cardiac damage. The data also supported increased proinflammatory cytokines such as interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α). As oxidative stress parameter increased in both liver and heart, there is also an increased in TNF-α due to an increased expression of inducible nitric oxide (NO) synthase, which led to a high production of NO. Moreover, HLD treatment explicitly weakens reasonability of hepatocytes and cardiomyocytes conceivably through G0/G1 or S stage capture or perhaps by means of enlistment of sub-G0/G1 DNA fragmentation and a sign of apoptosis.

Conclusions
Based on the outcomes, it tends to be inferred that consequences of the present examination uncovered HLD in combination of 2:3 applies most encouraging systemic damage by reactive oxygen species generation and hyperlipidemia and necroapoptosis of the liver and heart. Hence, outcome of this study may help to formulate health care strategy and warns about the food habit in universal population regarding the use of hydrogenated and saturated fats (vanaspati ghee) in diet.

Abstract

Background and purpose
C-reactive protein (CRP) is an inflammatory biomarker which prognosticates cardiovascular disease. Previous studies have reached mixed conclusions regarding the effect of vitamin C on reducing CRP or hs-CRP level. The present systematic review and meta-analysis was conducted to resolve these inconsistencies.

Materials and methods: Related articles published up to August 2018 were searched through PubMed, Scopus, Ovid, ISI web of science, Embase, and Cochrane databases by relevant keywords. Clinical trials which examined the effect of either vitamin C supplementation or vitamin C-enriched foods on CRP and hs-CRP levels were included. A total of 11 studies with 14 data sets involving 818 subjects were included.

Results
Overall, the pooled analysis revealed that vitamin C could decrease CRP level relative to placebo group (Weighted mean difference [WMD]=−0.73 mg/L: 95% CI: −1.30 to −0.15, p=0.013) with a considerable heterogeneity (I2=98%, p<0.001). Moreover, subgroup analyses revealed that the beneficial effect of vitamin C on CRP level alternation only was found in male (p=0.003), non-smoker (p=0.041), healthy (p=0.029) and younger participants (p=0.010). Vitamin C could improve CRP level only at doses of less than 500 mg/day (p=0.009). Regarding hs-CRP changes, the pooled analysis did not show any significant effect of vitamin C (WMD=−0.65 mg/L: 95% CI: −2.03 to 0.72, p=0.35). This finding was confirmed by all subgroup analyses expect for high quality articles in which hs-CRP level was elevated after vitamin C supplementation (p=0.026).

Conclusion
In conclusion, supplementation with vitamin C might have a significant effect only on CRP reduction. Further studies are needed to confirm this effect.

The effect of maternal position on fetal middle cerebral artery Doppler indices and its association with adverse perinatal outcomes: a pilot study
Authors: McLaren Rodney , Kalgi Bharati , Ndubizu Chima , Homel Peter , Haberman Shoshana , Minkoff Howard 
Published: March 2020

AbstractObjectiveThe aim of this study was to compare position-related changes in fetal middle cerebral artery (MCA) Doppler pulsatility indices (PI).MethodsA prospective study of 41 women with conditions associated with placental-pathology (chronic hypertension, pregestational diabetes, and abnormal analytes) and 34 women without those conditions was carried out. Fetal MCA Doppler velocity flow waveforms were obtained in maternal supine and left lateral decubitus positions. MCA PI Δ was calculated by subtracting the PI in the supine position from the PI in the left lateral position. Secondary outcomes included a composite of adverse perinatal outcomes (fetal growth restriction, oligohydramnios, and preeclampsia). χ2and Studentt-tests and repeated-measures analysis of variance were used.ResultsMCA PI Δ was significantly less for high-risk pregnant women ([P = 0.03]: high risk, left lateral PI, 1.90 ± 0.45 vs. supine PI, 1.88 ± 0.46 [Δ = 0.02]; low risk, left lateral PI, 1.90 ± 0.525 vs. supine PI, 1.68 ± 0.40 [Δ = 0.22]). MCA PI Δ was not significantly different between women who had a composite adverse outcome and women who did not have a composite adverse outcome (P = 0.843).ConclusionOur preliminary study highlights differences in position-related changes in fetal MCA PI between high-risk and low-risk pregnancies. These differences could reflect an attenuated ability of women with certain risk factors to respond to physiologic stress.
Privacy in Public: A Democratic Defense
Authors: Stahl Titus 
Published: March 2020

AbstractTraditional arguments for privacy in public suggest that intentionally public activities, such as political speech, do not deserve privacy protection. In this article, I develop a new argument for the view that surveillance of intentionally public activities should be limited to protect the specific good that this context provides, namely democratic legitimacy. Combining insights from Helen Nissenbaum’s contextualism and Jürgen Habermas’s theory of the public sphere, I argue that strategic surveillance of the public sphere can undermine the capacity of citizens to freely deliberate in public and therefore conflicts with democratic self-determination.
