Synthesis and Characterization of Ag@C-TiO2 Nanocomposite for Degradation of Sasirangan Textile Wastewater
Authors: Dewi Heny Puspita , Santoso Joko , Trianda Nur Firda , Rodiansono Rodiansono 
Published: December 2019

Carbon-titanium oxide nanocomposite (denoted as @C-TiO2) was successfully synthesized via hydrothermal method at 150°C for 24 h. The C-TiO2 nanocomposite was furtherly modified by adding an Ag metal dopant (denoted as Ag@C-TiO2) to improve and applied to the photocatalytic degradation of Sasirangan textile wastewater. The composite photocatalysts were characterized by XRD and UV–Vis DRS spectroscopies. XRD patterns showed that TiO2 in @C-TiO2 mainly consisted of a brookite phase, as indicated by a series sharp diffraction peak at 2θ = 27.2° (111), 31.5° (121) and 55.9° (241). The calculated band gap energy (Eg) derived from UV-Vis DRS spectra for TiO2, @C-TiO2, and Ag@C-TiO2 were 2.95 eV, 2.54 eV, and 2.74 eV, respectively. Ag@C-TiO2 photocatalyst was found to be active for the photocatalytic degradation of Sasirangan textile wastewater, as indicated by the change of wastewater color from dark to clear. The quantitative photocatalytic activity of Ag@C-TiO2 was evaluated in the degradation of methylene blue, whereas the conversion of methylene blue was 41.3%. The addition of Ag to @C-TiO2 is believed to play an essential role in the enhancement of photocatalytic activity.
Personality Traits, Demographic Factors and Entrepreneurial Intentions: Improved Understanding from a Moderated Mediation Study
Authors: Ahmed Tariq , Klobas Jane E , Ramayah T. 
Published: December 2019

Abstract
Studies with contradictory results have been published on the relationship between personality and entrepreneurial intentions. This paper examines the role of personality traits and demographic factors in the formation of business start-up intention, using a moderated mediation model derived from the theory of planned behaviour. Data were collected from 324 final year MBA students using a structured survey instrument and analysed with single and multi-group structural equation modelling (SEM). Innovativeness, risk propensity and stress tolerance had small but significant indirect effects on entrepreneurial intentions; these effects were mediated by attitudes to entrepreneurship and perceived behavioural control. Need for autonomy and stress tolerance were not significant, neither was family background nor work experience. Observation of small, indirect personality effects suggests some resolution to the contradictory results observed until now; helps career counsellors and university selection panels to identify candidates with the potential to become entrepreneurs; and provides support for calls for policy makers and university administrators to develop educational environments and socio-political infrastructure that provides opportunities for students to exploit their creative and risk-taking traits and develop positive attitudes to entrepreneurship.
Quality assessment of DEM derived from topographic maps for geomorphometric purposes
Authors: Szypuła Bartłomiej 
Published: December 2019

AbstractDigital elevation models (DEMs) play a significant role in geomorphological research. For geomorphologists reconstructing landform and drainage structure is frequently as important as elevation accuracy. Consequently, large-scale topographic maps (with contours, height points and watercourses) constitute excellent material for creating models (here called Topo-DEM) in fine resolution. The purpose of the conducted analyses was to assess the quality of Topo-DEM against freely-available global DEMs and then to compare it with a reference model derived from laser scanning (LiDAR-DEM). The analysis also involved derivative maps of geomorphometric parameters (local relief, slope, curvature, aspect) generated on the basis of Topo-DEM and LiDAR-DEM. Moreover, comparative classification of landforms was carried out. It was indicated that Topo-DEM is characterised by good elevation accuracy (RMSE <2 m) and reflects the topography of the analyzed area surprisingly well. Additionally, statistical and percentage metrics confirm that it is possible to generate a DEM with very good quality parameters on the basis of a large-scale topographic map (1:10,000): elevation differences between Topo-DEM and: 1) topographic map amounted from−1.68 to +2.06 m,MAEis 0.10 m, RMSE 0.16 m; 2) LiDAR-DEM (MAE 1.13 m, RMSE 1.69 m, SD 1.83 m); 3) GPS RTK measurements amounted from−3.6 to +3.01 m, MAE is 0.72 m, RMSE 0.97 m, SD 0.97 m. For an area of several dozen km2Topo-DEM with 10×10 m resolution proved more efficient than detailed (1×1 m) LiDAR-DEM.
Intercession and the Taboo and Stigma on Mental Health and Doctrinal Anomalies: Pastoral and Theological Implications of Public Prayer Practices
Authors: van Ommen Armand Léon 
Published: December 2019

Abstract
Prayers of intercession cover a wide range of topics, yet prayers for mental health or issues around sexuality or divorce prove to be taboo and stigmatised. This article interprets this finding from empirical research with the theories of taboo as outlined by Alasdair MacIntyre and Mary Douglas. The article offers pastoral-theological reflections on the problem of taboo and stigma – caused by doctrine or cultural norms – in intercession. The article argues that the practices of solidarity, naming, and hospitality reframe the way taboo and stigma can be thought about theologically and therefore eventually might influence intercession in public worship.
What Are They Saying About Church Management? Patterns, Problems, and Considerations for Proceeding
Authors: Kheng Christina 
Published: December 2019

Abstract
In recent years, the Roman Catholic Church has seen an increase in pastoral education programs, literature, and other resources on church management. Though positive outcomes have been noted, there is much room for improvement in the way management ideas have been applied to the ecclesial context. This article examines patterns of engagement with management science in Catholic pastoral resources, and notes the key conflicts that have arisen. It then outlines considerations for a way forward in the inter-disciplinary engagement. These include the need for recognition of the limitations of management, critical reflexivity in the appropriation of management ideas, and dialogical discernment in the application of the faith tradition towards improving management theory and practice.
Evaluation ofSaccharomyces cerevisiaeWine Yeast Competitive Fitness in Enologically Relevant Environments by Barcode Sequencing

Published: December 2019

AbstractWhen a wine yeast is inoculated into grape juice the potential variation in juice composition that confronts it is huge. Assessing the performance characteristics of the many commercially available wine yeasts in the many possible grape juice compositions is a daunting task. To this end we have developed a barcoded Saccharomyces cerevisiae wine yeast collection to facilitate the task of performance assessment that will contribute to a broader understanding of genotype-phenotype relations. Barcode sequencing of mixed populations is used to monitor strain abundance in different grape juices and grape juice-like environments. Choice of DNA extraction method is shown to affect strain-specific barcode count in this highly related set of S. cerevisiae strains; however, the analytical approach is shown to be robust toward strain dependent variation in DNA extraction efficiency. Of the 38 unique compositional variables assessed, resistance to copper and SO2 are found to be dominant discriminatory factors in wine yeast performance. Finally, a comparison of competitive fitness profile with performance in single inoculum fermentations reveal strain dependent correspondence of yeast performance using these two different approaches.

Asymptotic Stability of an Abstract Delay Functional-Differential Equation
Authors: Tchuenche J. M. 
Published: December 2019

We study the exponential asymptotic stability of an abstract functional-differential equation with a mixed type of deviating arguments, namely: c which might represent the gestation period of the population and r(u(t)), a suitably defined function. The equation is reduced to its equivalent integral form and solved via Laplace transform method. An interesting connection of our study is with generalizations of populations with potentially complex (chaotic) dynamics.
The SVD-Fundamental Theorem of Linear Algebra
Authors: Akritas A. G. , Malaschonok G. I. , Vigklas P. S. 
Published: December 2019

Given an m × n matrix A, with m ≥ n, the four subspaces associated with it are shown in Fig. 1 (see [1]).

Fig. 1. The row spaces and the nullspaces of A and AT; a1 through an and h1 through hm are abbreviations of the alignerframe and hangerframe vectors respectively (see [2]).
The Fundamental Theorem of Linear Algebra tells us that N(A) is the orthogonal complement of R(AT). These four subspaces tell the whole story of the Linear System Ax = y. So, for example, the absence of N(AT) indicates that a solution always exists, whereas the absence of N(A) indicates that this solution is unique. Given the importance of these subspaces, computing bases for them is the gist of Linear Algebra. In “Classical” Linear Algebra, bases for these subspaces are computed using Gaussian Elimination; they are orthonormalized with the help of the Gram-Schmidt method. Continuing our previous work [3] and following Uhl’s excellent approach [2] we use SVD analysis to compute orthonormal bases for the four subspaces associated with A, and give a 3D explanation. We then state and prove what we call the “SVD-Fundamental Theorem” of Linear Algebra, and apply it in solving systems of linear equations.
Persistence and Stability of a Food Chain Model with Mixed Selection of Functional Responses
Authors: Maiti A. , Patra B. , Samanta G. P. 
Published: December 2019

One approach to the study of an ecological community begins with an important object: its food web. Theoretical studies of food web must contend with the question of how to couple the large number of interacting species. One line of investigation assumes that the “building blocks” are species interacting in a pairwise fashion. The model we analyze in this paper describes a tritrophic food chain composed of logistic prey, a classical Lotka-Volterra functional response for prey and predator, and a Holling type-II functional response for predator and superpredator. Dynamical behaviours such as boundedness, stability, persistence, bifurcation et cetera of the model are studied critically. Computer simulations are carried out to explain the analytical findings. Finally it is discussed how these ideas illuminate some of the observed properties of real populations in the field, and explores practical implications.
Modelling Complex Chemical Processes in Homogeneous Solutions: Automatic Numerical Simulation
Authors: Klymenko O. V. , Svir I. B. 
Published: December 2019

Two algorithms for the determination of the necessary limit of local error for the numerical solution of ordinary differential equation (ODE) systems describing homogeneous chemical and biochemical processes, and for the evaluation of their stiffness are developed. The approach for finding the necessary limit of local error of a numerical ODE solver is justified by the proof of the corresponding theorems. The application of the new algorithms implemented in version 2.1 of KinFitSim software to the simulation of real chemical systems is considered on the example of Belousov-Zhabotinsky reaction.

Prostat kanseri
erkeklerdeki en sık kanserdir. Gleason skorlaması (GS), transrektal ya da
transperitoneal yoldan alınan biyopsi materyallerindeki glandüler yapıların
diferansiyasyon derecesinin 1 ile 5 arasında puanlandırılması ile elde edilen
sistemdir. Transrektal iğne biyopsisi ve
radikal prostatektomi spesmeni arasındaki GS uyumu önemlidir ve pek çok
çalışmada bu uyumun düşük olduğu gösterilmiştir. Bu çalışmada kiniğimizde yapılan
TRUS biyopsiler sonucunda Prostat adenokarsinom
(PCA) tanısı alan hastaların retropubik radikal prostatektomi (RRP)
sonrası GS arasındaki uyum değerlendirilmiştir.

MATERYEL VE METOD: SDÜ
Üroloji Kliniği‘nde 2015 -2018 yılları arasında PSA yüksekliği (&gt;2.5 ng/ml)
veya anormal dijital rektal muayene bulguları olan, sonrasında RRP yapılmış 182
hastanın patoloji sonuçları retrospektif olarak değerlendirildi.

BULGULAR: 12 kor TRUS biyopsi
yapılan ve prostat kanseri tanısı konulup RRP yapılan 182 hastanın kayıtları
retrospektif olarak değerlendirildi. Hastaların ortanca yaşı 67 (49-85) yıl,
preoperatif total PSA median değeri 8.28 ng/ml (2,6-40,43) olarak saptandı. Hastaların ortalama
prostat hacimleri 70 cc (40-130 cc ) olarak değerlendirildi. Biyopsi sonrası
elde edilen GS ile RP sonrası patolojik spesmen GS arasındaki uyuma
bakıldığında 100 (%54,6) hastanın preoperatif belirlenen GS skoru ile RRP
skorunun aynı olduğu gözlenmiştir.

SONUÇ:
TRUS biyopsi ile RP GS arasındaki uyum sorunu devam etmektedir. Her ne
kadar verilerimiz literatür ile uyumlu olsa da alternatif biyopsi değerlendirme
yöntemlerine ihtiyacımız olduğu görülmüştür.

Published: December 2019

This study explores personal teaching efficacy beliefs of basic school teachers in Ghana undergoing recertification to upgrade their qualification. The study examines whether the personal teaching efficacy of the teachers is affected by their subject specialisation. A descriptive survey design was employed for the study. Data for the study was obtained from a total of 185 in-service teachers selected randomly from a group of teachers who were undergoing recertification from diploma to bachelor degree in basic education in a teacher education university in Ghana. Teacher Sense of Efficacy Scale (TSES) was adapted and used to measure in-service teachers’ personal teaching efficacy beliefs. The findings of the study showed that in-service teachers have a high sense of personal teaching efficacy. The study also revealed that in-service teachers’ level of self-efficacy was not affected by their subject specialization.

Abstract
Background: Phenomics provides new technologies and platforms as a systematic phenome-genome approach. However, few studies have reported on the systematic mining of shared genetics among clinical biochemical indices based on phenomics methods, especially in China. This study aimed to apply phenomics to systematically explore shared genetics among 29 biochemical indices based on the Fangchenggang Area Male Health and Examination Survey cohort. Result: A total of 1,999 subjects with 29 biochemical indices and 709,211 single nucleotide polymorphisms (SNPs) were subjected to phenomics analysis. Three bioinformatics methods, namely, Pearson’s test, Jaccard’s index, and linkage disequilibrium score regression, were used. The results showed that 29 biochemical indices were from a network. IgA, IgG, IgE, IgM, HCY, AFP and B12 were in the central community of 29 biochemical indices. Key genes and loci associated with metabolism traits were further identified, and shared genetics analysis showed that 29 SNPs (P < 10-4) were associated with three or more traits. After integrating the SNPs related to two or more traits with the GWAS catalogue, 31 SNPs were found to be associated with several diseases (P < 10-8). Using ALDH2 as an example to preliminarily explore its biological function, we also confirmed that the rs671 (ALDH2) polymorphism affected multiple traits of osteogenesis and adipogenesis differentiation in 3T3-L1 preadipocytes. Conclusion: All these findings indicated a network of shared genetics and 29 biochemical indices, which will help fully understand the genetics participating in biochemical metabolism.
