Authors: Al-Abdullah Abdullah Saad , Al-Bounni Roula S. , Al-Omari Mohammad 
Published: September 2017

Objective: To evaluate the color stability of Tetric® N-Ceram Bulk Fill composite restorative material after immersion in three different (energy drink, protein supplement solution, and combination of energy drink and protein supplement solution) drinks. Materials and Methods: Composite resin disks, 2 mm in depth and 5 mm in diameter, were prepared from the Tetric® N-Ceram Bulk Fill composite restorative material. Specimens were tested after immersion and aging in energy drink (Red Bull) alone, protein supplement solution alone, and in combination with energy drink and protein supplement. Deionized water was used as a control group. Specimens were stored at room temperature of ±23°C for a period of one week in each drink. Color was assessed in the CIELAB using Color Eye 7000A Spectrophotometer. Color differences in different group specimens were measured. Mean values were statistically analyzed using one-way analysis of variance (ANOVA). Further Tukey’s multiple comparison tests were applied to know the differences between the group of specimens. A p value of p < 0.05 was set as significance level. Results: N-Ceram Bulk Fill composite showed Δ L, Δ a, Δ b, and Δ E mean and standard deviation values when immersed in deionized water (–2.6 ± 3.24, 0.16 ± 0.19, 0.32 ± 1.26, and 3.51 ± 2.47), energy drink (–4.19 ± 4.24, 0.21 ± 0.21, 1.57 ± 1.32, and 5.40 ± 3.11), protein supplement (62.71 ± 12.48, –2.63 ± 0.7, 7.7 ± 5.67, and 63.45 ± 12.56), combined energy drink and protein supplement (68.52 ± 13.43, –4.06 ± 1.73, 10.94 ± 5.31, and 69.71 ± 13.42), respectively. All the color coordinates (Δ L, Δ a, and Δ b) showed statistically significant difference, p < 0.001. The color change of N-Ceram Bulk Fill composite specimens Δ E occurred by immersion in energy drink, protein supplement solution, and combined solution of energy drink and protein supplement after seven days was found to be statistically significant p < 0.001. Conclusion: The study’s finding suggests that the energy drink (Red Bull), protein supplement (ISOPURE), and combined immersion in energy drink and protein supplements caused perceptible and clinically unacceptable color change in the Tetric® N-Ceram Bulk Fill composite material. This color change was remarkably high with a combined immersion in energy drink and protein supplement solution.

Background or Purpose: The evaluation of retinal hemorrhages in the setting of suspected abusive head trauma (AHT) has important medical, social, and legal implications. Challenges include late presentation after retinal hemorrhages have resolved and differentiating AHT-related retinal changes from mimicking pathologies. To date, angiographic evidence of peripheral retinal injury in AHT has been reported in small series, but further study is needed to determine the prevalence and long-term sequelae of these findings. The purpose of this study was to describe fluorescein angiography (FA) findings in pediatric patients with a history of definite AHT and demonstrate the potential utility of FA in evaluating cases of suspected abuse with late presentation. Methods: Retrospective case series of 10 eyes in 5 pediatric patients with a history of definite AHT. RetCam fundus photography images and digital FA were performed. Results: Peripheral retinal nonperfusion affected 10 of 10 eyes in patients with a history of definite AHT. These changes persisted after acute retinal hemorrhages had resolved. Conclusions: “Retinal surveys” using FA provide angiographic evidence of peripheral retinal nonperfusion that may be a sign of AHT. This series adds to the growing body of cases reporting similar AHT-related findings and additionally demonstrates the longevity of these pathologic changes after trauma, which has not been previously described. Fluorescein angiography may offer a distinct advantage in evaluating cases of suspected abuse with late presentation to medical care when pathognomonic retinal hemorrhages may no longer be present. Further study is needed to determine the prevalence and long-term sequelae of these findings.

Published: September 2017

Inhaled corticosteroid (ICS) use is associated with an increased risk of pneumonia. This study was performed to determine if ICS use is associated with an increased risk of nontuberculous mycobacterial pulmonary disease (NTM-PD) or tuberculosis (TB).We conducted a population-based nested case–control study using linked laboratory and health administrative databases in Ontario, Canada, including adults aged ≥66 years with treated obstructive lung disease (i.e.asthma, chronic obstructive pulmonary disease (COPD) or asthma–COPD overlap syndrome) between 2001 and 2013. We estimated odds ratios comparing ICS use with nonuse among NTM-PD and TB cases and controls using conditional logistic regression.Among 417 494 older adults with treated obstructive lung disease, we identified 2966 cases of NTM-PD and 327 cases of TB. Current ICS use was associated with NTM-PD compared with nonuse (adjusted OR (aOR) 1.86, 95% CI 1.60–2.15) and was statistically significant for fluticasone (aOR 2.09, 95% CI 1.80–2.43), but not for budesonide (aOR 1.19, 95% CI 0.97–1.45). There was a strong dose–response relationship between incident NTM-PD and cumulative ICS dose over 1 year. There was no significant association between current ICS use and TB (aOR 1.43, 95% CI 0.95–2.16).This study suggests that ICS use is associated with an increased risk of NTM-PD, but not TB.
Spatial analysis of cluster randomised trials: a systematic review of analysis methods
Authors: Jarvis Christopher , Di Tanna Gian Luca , Lewis Daniel , Alexander Neal , Edmunds W. John 
Published: September 2017

Abstract
Background
Cluster randomised trials (CRTs) often use geographical areas as the unit of randomisation, however explicit consideration of the location and spatial distribution of observations is rare. In many trials, the location of participants will have little importance, however in some, especially against infectious diseases, spillover effects due to participants being located close together may affect trial results. This review aims to identify spatial analysis methods used in CRTs and improve understanding of the impact of spatial effects on trial results.

Methods
A systematic review of CRTs containing spatial methods, defined as a method that accounts for the structure, location, or relative distances between observations. We searched three sources: Ovid/Medline, Pubmed, and Web of Science databases. Spatial methods were categorised and details of the impact of spatial effects on trial results recorded.

Results
We identified ten papers which met the inclusion criteria, comprising thirteen trials. We found that existing approaches fell into two categories; spatial variables and spatial modelling. The spatial variable approach was most common and involved standard statistical analysis of distance measurements. Spatial modelling is a more sophisticated approach which incorporates the spatial structure of the data within a random effects model. Studies tended to demonstrate the importance of accounting for location and distribution of observations in estimating unbiased effects.

Conclusions
There have been a few attempts to control and estimate spatial effects within the context of human CRTs, but our overall understanding is limited. Although spatial effects may bias trial results, their consideration was usually a supplementary, rather than primary analysis. Further work is required to evaluate and develop the spatial methodologies relevant to a range of CRTs.

Published: September 2017

Abstract
Background
Arthroscopic reduction has become increasingly popular as an alternative to open reduction for the treatment of developmental dysplasia of the hip (DDH). However, patient outcomes beyond one and a half years after surgery remain unclear. The purpose of this study is to report the medium-term outcomes of walking-age patients who received arthroscopic reduction after an unsuccessful closed reduction. This research was conducted as part of a retrospectively registered study.

Methods
We performed arthroscopic reduction in eight children with DDH after failed closed reduction between January 2010 and January 2012 and followed all cases for a minimum of 5 years. Arthroscopic reduction was performed using a two-portal approach without traction. Capsular release and resection of the transverse acetabular ligament were also performed if needed. Patient demographics, clinical variables, anatomical assessment measures, and post-operative complications were extracted from medical records.

Results
We treated five male and three female patients with an average age at operation of 15.6 months (range, 12 to 22 months). All obstacles to reduction were corrected arthroscopically. Concentric reduction of the hip joint was observed in post-operative X-rays in all cases. The average safe zone was increased from 17.5° (8° to 30°) to 42.1° (36° to 50°) after the operation. The average acetabular (AC) index was reduced from 40.3° (33° to 65°) to 21.9° (19° to 26°) at the end of follow-up. No complications occurred and no patients developed necrosis of the femoral head, recurrent dislocation, or residual hip dysplasia.

Conclusions
Arthroscopic reduction is a suitable surgical procedure for the treatment of DDH among walking-age children with failed closed reduction and severe dislocation. This method is quick and safe, and it can be performed without post-operative complications over the medium term.

Performance of Soil Termiticides in Open Field and Under Roof Overhang
Authors: Acda Menandro N 
Published: September 2017

The study investigated the difference in performance of termiticides using concrete slab test installed in open field and under roof overhang. Soil treated with cypermethrin and chlorpyrifos under roof overhang showed lower percentage of termite penetration compared to those in open field in each year of evaluation. However, in both conditions termites were already able to penetrate treated plots during the first year of trial. The high percentage of plots attacked by termites could be attributed to several environmental factors such as presence of a wider diversity of termite species, moisture, temperature, soil properties, microbial communities, etc. common in tropical climates. The results from these two modes of installation could affect protocol used for field trial and the granting of registration or performance warranty to candidate termiticides in tropical countries.
A political history of visual display
Authors: Krogstad Anne 
Published: September 2017

Abstract
Visual presentations of political leaders have a long tradition. They convey information about who a politician is and – to a certain degree – his or her political positions. As studiously crafted displays of ideals, such images may also enlarge, challenge, complete or be a substitute for qualities and values. These capacities make images effective tools of political persuasion. While not aiming at a comprehensive overview, this article tries to capture the visual mode of political communication by studying how the portrayal of politicians provides the public with knowledge about the world of politics during different information eras. The main question is how the development of new forms of media, each with individual possibilities and restrictions regarding display, access, reach and storage, facilitate specific forms of visual politics. Examples from each historical era are discussed. Central questions include what images are displayed, how are they displayed and with what media technology. Also examined are rhetorical functions, the images’ institutional anchorage and forms of interaction. Visual presentations of politicians are analysed in their face-to-face interaction with a public, as well as in sculptures, paintings, photographs, film, television and digital media. The examples range from the Greek agora, where citizens could assemble and be taken in ‘at a single view’, to the Nordic prime ministers’ profile pictures on Facebook.

Com o objetivo de avaliar componentes agronômicos qualitativos e caracterizar morfologicamente variedades de mandioca em função da época de colheita, conduziu-se o experimento na Universidade Estadual do Sudoeste da Bahia, campus de Vitória da Conquista- BA. O delineamento experimental utilizado foi o de blocos ao acaso, com 3 repetições, e os tratamentos arranjados segundo o esquema de parcelas subdivididas, com cinco variedades (Sergipe, Caitité, Platinão, Roxinha e Pão da China) nas parcelas e seis épocas de colheita nas subparcelas (270, 330, 390, 450, 510 e 570 dias após o plantio). Foram avaliadas: altura de plantas, diâmetro de caule, área foliar total e índice de área foliar. Além disso, foi feita a caracterização morfológica das plantas. Os genótipos apresentaram comportamento diferenciado para a característica altura de plantas, a variedade Roxinha foi superior até 450 dias após o plantio, sendo que aos 510 e 570 dias, a variedade Caitité foi superior. Os genótipos Pão da China, Platinão e Sergipe apresentaram maior diâmetro de caule que a variedade Caitité, sem diferenças entre épocas. Para as características índice de área foliar e área foliar total, houve redução dos índices na sexta colheita, devido a fatores climáticos no período. A variedade Sergipe apresentou a maior retenção foliar. Na caracterização morfológica dos genótipos, notou-se diferenças entre os materiais e características estudadas.
On 2-Absorbing Primary Submodules of Modules over Commutative Rings
Authors: Mostafanasab Hojjat , Yetkin Ece , Tekir Ünsal , Yousefian Darani Ahmad 
Published: September 2017

Abstract
All rings are commutative with 1 ≠ 0, and all modules are unital. The purpose of this paper is to investigate the concept of 2-absorbing primary submodules generalizing 2-absorbing primary ideals of rings. Let M be an R-module. A proper submodule N of an R-module M is called a 2-absorbing primary submodule of M if whenever a; b ∈ R and m ∈ M and abm ∈ N, then am ∈ M-rad(N) or bm ∈ M-rad(N) or ab ∈(N :R M). It is shown that a proper submodule N of M is a 2-absorbing primary submodule if and only if whenever I1I2K ⊆ N for some ideals I1; I2 of R and some submodule K of M, then I1I2 ⊆ (N :R M) or I1K ⊆ M-rad(N) or I2K ⊆ M-rad(N). We prove that for a submodule N of an R-module M if M-rad(N) is a prime submodule of M, then N is a 2-absorbing primary submodule of M. If N is a 2-absorbing primary submodule of a finitely generated multiplication R-module M, then (N :R M) is a 2-absorbing primary ideal of R and M-rad(N) is a 2-absorbing submodule of M.
Positive solutions for semilinear elliptic systems with sign-changing potentials
Authors: Zeddini Noureddine , Ben Dkhil Adel 
Published: September 2017

Abstract
In this paper, we study the existence of positive solutions of the Dirichlet problem -Δu = λ p(x)f(u; v) ; -Δv = λ q(x)g(u; v); in D, and u = v = 0 on ∂∞D, where D ⊂ Rn (n ≥ 3) is an C1,1-domain with compact boundary and λ > 0. The potential functions p; q are not necessarily bounded, may change sign and the functions f; g : ℝ2 → ℝ are continuous with f(0; 0) > 0, g(0; 0) > 0. By applying the Leray- Schauder fixed point theorem, we establish the existence of positive solutions for λ sufficiently small.
Equivalence of Control Systems on the Pseudo-Orthogonal Group SO (2, 1)0
Authors: Biggs Rory , Remsing Claudiu C. 
Published: September 2017

Abstract
We consider left-invariant control affine systems on the matrix Lie group SO (2, 1)0. A classification, under state space equivalence, of all such full-rank control systems is obtained. First, we identify certain subsets on which the group of Lie algebra automorphisms act transitively. We then systematically identify equivalence class representatives (for single-input, two-input and three-input control systems). A brief comparison of these classification results with existing results concludes the paper.

Published: September 2017

Abstract
We consider the generalized Hecke groups Hp,q generated by X(z) = -(z -λp)-1, Y (z) = -(z +λq)-1 with and where 2 ≤ p ≤ q < ∞, p+q > 4. In this work we study the structure of genus 0 normal subgroups of generalized Hecke groups. We construct an interesting genus 0 subgroup called even subgroup, denoted by . We state the relation between commutator subgroup H′p,q of Hp,q defined in [1] and the even subgroup. Then we extend this result to extended generalized Hecke groups H̅p,q.

Abstract
The aim of this work is to introduce some types of filters in Hilbert algebras. Some theorems are stated and proved which determine the relationship between these notions and other filters of Hilbert algebra and by some examples we show that these concepts are different. The relationships between these filters and quotient algebras that are constructed via these filters are described.
Some bounds for the relative generalized Hamming weights of some evaluation codes
Authors: Sarabia Manuel González 
Published: September 2017

Abstract
In this paper we find some bounds for the relative generalized Hamming weights of some codes parameterized by a set of monomials of the same degree. Also we compare the relative generalized Hamming weights of the codes CX(d) and CX′(d) when X′ is embedded in X. We use these results to obtain some lower bounds for the relative generalized Hamming weights of the codes parameterized by the edges of any connected bipartite graph with bipartition (V1, V2) and where |V1| = n1, |V2| = n2, in terms of the relative generalized Hamming weights of the codes associated to the projective tori Tn₁-1 and Tn₂-1.
On the Kolmogorov forward equations within Caputo and Riemann-Liouville fractions derivatives
Authors: Alipour Mohsen , Baleanu Dumitru 
Published: September 2017

Abstract
In this work, we focus on the fractional versions of the well-known Kolmogorov forward equations. We consider the problem in two cases. In case 1, we apply the left Caputo fractional derivatives for α ∈ (0, 1] and in case 2, we use the right Riemann-Liouville fractional derivatives on R+, for α ∈ (1, +∞). The exact solutions are obtained for the both cases by Laplace transforms and stable subordinators.
On Generalized Jacobsthal and Jacobsthal-Lucas polynomials
Authors: Catarino Paula , Morgado Maria Luisa 
Published: September 2017

Abstract
In this paper we introduce a generalized Jacobsthal and Jacobsthal-Lucas polynomials, Jh,n and jh,n, respectively, that consist on an extension of Jacobsthal's polynomials Jn(𝑥) and Jacobsthal-Lucas polynomials jn(𝑥). We provide their properties and a generalization of the usual identities. We also present, for each one of these generalized polynomials, their ordinary generating functions and matrices. In the last part of the paper, we present some special kind of tridiagonal matrices whose entries are elements of these generalized polynomials.
From lattices to Hv-matrices
Authors: Křehlík Štěpán , Novák Michal 
Published: September 2017

Abstract
In this paper we study the concept of sets of elements, related to results of an associative binary operation. We discuss this issue in the context of matrices and lattices. First of all, we define hyperoperations similar to those used when constructing hyperstructures from quasi-ordered semigroups. This then enables us to show that if entries of matrices are elements of lattices, these considerations provide a natural link between matrices, some basic concepts of the hyperstructure theory including Hv-rings and Hv-matrices and also one recent construction of hyperstructures.

Published: September 2017

Abstract
The boundedness of the weighted differentiation composition opera- tor from the logarithmic Bloch space to the weighted-type space is characterized in terms of the sequence (zn)n∈N0. An asymptotic estimate of the essential norm of the operator is also given in terms of the sequence, which gives a characterization for the compactness of the operator.
Modeling a fuzzy system for assisting the customer targeting decisions in retail companies
Authors: Micu Angela-Eliza 
Published: September 2017

Abstract
This paper reveals a proposal of a decision support system, enabling retail companies' marketing managers with powerful tools for the customers' portfolios targeting. The innovative methodological approach highlights a fuzzy algorithm based system that captures and computes relevant information about customers, providing a managerial support for making the most effective decisions, according to different degrees of affiliation assigned to customers. The contributions of fuzzy algorithms on targeting decisions reflects the affiliation of customers to a specific cluster, based on computation of the input vectors, income and seniority, leading to performing marketing decisions.
