Authors: Rybinski Henryk , Skonieczny Lukasz , Koperwas Jakub , Struk Waclaw , Stepniak Jolanta , Kubrak Weronika 
Published: July 2017

Purpose
The purpose of this paper is to present a solution for building an institutional information system (IIS) for the university, so that it combines the functionality of institutional repository (IR) with the functionality of current research information system (CRIS). The paper presents functionality of a system that has been implemented at Warsaw University of Technology (WUT), which solves the requirements of both system types. In addition, applied AI technologies aiming at providing features attractive for the system beneficiaries are presented.

Design/methodology/approach
The authors have reviewed various approaches to IIS, analyzed the problems observed by researchers in combining CRIS with IR, and have shown how the problems can be solved within a system that integrates various functionalities. Based on this analysis, the authors have implemented software Ω-ΨR (OMEGA-PSIR) for an academic IIS, which integrates requirements of both system types, and then deployed it at WUT.

Findings
It is shown that although a classical repository is an important part of the CRIS/IR system, the essential value of the solution is in providing analytical tools for “research management.” Based on the example of OMEGA-PSIR, the authors have also presented how the researcher-centric approach influences the acceptance rate of the academic community. It is also shown how the researcher-centric approach can take advantage from integrating the conflicting functionalities of IR and CRIS.

Practical implications
The paper bridges the gap between theory and practice in the area of IIS for academic institutions. It constructively discusses the role of institutional IR and it provides guides how to develop a system combining functionalities of CRIS and IR, as well as how to make IIS more attractive for the users by making the system researcher centric.

Originality/value
The survey of various approaches to IIS is unique. The research-centric approach and its implementation within OMEGA-PSIR system are original. Lessons learned from deploying the software at the WUT are of great value for institutions planning to install IR/CRIS solutions. A survey research concerning the system usability is provided, showing practical usefulness of the proposed approach.

Geometrically nonlinear analysis of shells by various dynamic relaxation methods
Authors: Rezaiee-Pajand Mohammad , Estiri Hossein 
Published: July 2017

Purpose
Numerical experiences reveal that the performances of the dynamic relaxation (DR) method are related to the structural types. This paper is devoted to compare the DR schemes for geometric nonlinear analysis of shells. To achieve this task, 12 famous approaches are briefly introduced. The differences among these schemes are between the estimation of the time step, the mass and the damping matrices. In this study, several benchmark structures are analyzed by using these 12 techniques. Based on the number of iterations and the analysis duration, their performances are graded. Numerical findings reveal the high efficiency of the kinetic DR (kdDR) approach and Underwood’s strategy.

Design/methodology/approach
Up to now, the performances of various DR algorithms for geometric nonlinear analysis of thin shells have not been investigated. In this paper, 12 famous DR methods have been used for solving these structures. It should be noted that the difference between these approaches is in the estimation of the fictitious parameters. The aforementioned techniques are used to solve several numerical samples. Then, the performances of all schemes are graded based on the number of iterations and the analysis duration.

Findings
The final ranking of each strategy will be obtained after studying all numerical examples. It is worth emphasizing that the number of iterations and that of convergence points of the arc length algorithms are dependent on the value of the initial arc length. In other words, a slight change in the magnitude of the arc length may lead to the wrong responses. Contrary to this behavior, the analyzer’s role in the dynamic relaxation techniques is considerably less than the arc length method. In the DR strategies when the answer approaches the limit points, the iteration number increases automatically. As a result, this algorithm can be used to analyze the structures with complex equilibrium paths.

Research limitations/implications
Numerical experiences reveal that the DR method performances are related to the structural types. This paper is devoted to compare the DR schemes for geometric nonlinear analysis of shells.

Practical implications
Geometric nonlinear analysis of shells is a sophisticated procedure. Consequently, extensive research studies have been conducted to analyze the shells efficiently. The most important characteristic of these structures is their high resistance against pressure. This study demonstrates the performances of various DR methods in solving shell structures.

Originality/value
Up to now, the performances of various DR algorithms for geometric nonlinear analysis of thin shells are not investigated.
A robust cascaded controller for DC-DC Boost and Cuk converters
Authors: Ahmad Fiaz , Rasool Akhtar , Ozsoy Esref Emre , Sabanoviç Asif , Elitas Meltem 
Published: July 2017

Purpose
This paper aims to propose a robust cascaded controller based on proportional-integral (PI) and continuous sliding mode control.

Design/methodology/approach
Cascaded control structure is an attractive control scheme for DC-DC power converters. It has a two-loop structure where the outer loop contains PI controller and the inner loop uses sliding mode control (SMC). This structure thus combines the merits of both the control schemes. However, there are some issues that have prohibited its adoption in industry, the discontinuous nature of SMC which leads to variable switching frequency operation and is hard to realize practically. This paper attempts to overcome this issue by changing the discontinuous functionality of SMC to continuous by utilizing the concept of equivalent control.

Findings
The robustness of the controller designed is verified by considering various cases, namely, ideal case with no uncertainties, sudden variation of input supply voltage, load resistance, reference voltage, circuit-parameters and for noise disturbance. The controller effectiveness is validated by simulating the DC-DC boost and Cuk converters in SimPowerSystems toolbox of MATLAB/Simulink. It is shown that the performance of the proposed controller is satisfactory, and both reference output voltage and inductor current are tracked with little or no sensitivity to disturbances.

Originality/value
The results for various scenarios are interesting and show that the controller works quite satisfactorily for all the simulated uncertainties.

Systematic genetic dissection of chitin degradation and uptake in Vibrio cholerae
Authors: Hayes Chelsea A. , Dalia Triana N. , Dalia Ankur B. 
Published: July 2017

SummaryVibrio cholerae is a natural resident of the aquatic environment, where a common nutrient is the chitinous exoskeletons of microscopic crustaceans. Chitin utilization requires chitinases, which degrade this insoluble polymer into soluble chitin oligosaccharides. These oligosaccharides also serve as an inducing cue for natural transformation in Vibrio species. There are 7 predicted endochitinase‐like genes in the V. cholerae genome. Here, we systematically dissect the contribution of each gene to growth on chitin as well as induction of natural transformation. Specifically, we created a strain that lacks all 7 putative chitinases and from this strain, generated a panel of strains where each expresses a single chitinase. We also generated expression plasmids to ectopically express all 7 chitinases in our chitinase deficient strain. Through this analysis, we found that low levels of chitinase activity are sufficient for natural transformation, while growth on insoluble chitin as a sole carbon source requires more robust and concerted chitinase activity. We also assessed the role that the three uptake systems for the chitin degradation products GlcNAc, (GlcNAc)2 and (GlcN)2, play in chitin utilization and competence induction. Cumulatively, this study provides mechanistic details for how this pathogen utilizes chitin to thrive and evolve in its environmental reservoir.

Published: July 2017

SummarySalar de Uyuni (SdU), with a geological history that reflects 50 000 years of climate change, is the largest hypersaline salt flat on Earth and is estimated to be the biggest lithium reservoir in the world. Its salinity reaches saturation levels for NaCl, a kosmotropic salt, and high concentrations of MgCL2 and LiCl, both salts considered important chaotrophic stressors. In addition, extreme temperatures, anoxic conditions, high UV irradiance, high albedo and extremely low concentrations of phosphorous, make SdU a unique natural extreme environment in which to contrast hypotheses about limiting factors of life diversification. Geophysical studies of brines from different sampling stations show that water activity is rather constant along SdU. Geochemical measurements show significant differences in magnesium concentration, ranging from 0.2 to 2M. This work analyses the prokaryotic diversity and community structure at four SdU sampling stations, selected according to their location and ionic composition. Prokaryotic communities were composed of both Archaea (with members of the classes Halobacteria, Thermoplasmata and Nanohaloarchaea, from the Euryarchaeota and Nanohaloarcheota phyla respectively) and Bacteria (mainly belonging to Bacteroidetes and Proteobacteria phyla). The important differences in composition of microbial communities inversely correlate with Mg2+ concentration, suggesting that prokaryotic diversity at SdU is chaotropic dependent.
Fibrobacter communities in the gastrointestinal tracts of diverse hindgut‐fermenting herbivores are distinct from those of the rumen
Authors: Neumann Anthony P. , McCormick Caroline A. , Suen Garret 
Published: July 2017

SummaryThe genus Fibrobacter contains cellulolytic bacteria originally isolated from the rumen. Culture‐independent investigations have since identified Fibrobacter populations in the gastrointestinal tracts of numerous hindgut‐fermenting herbivores, but their physiology is poorly characterized due to few representative axenic cultures. To test the hypothesis that novel Fibrobacter diversity exists in hindgut fermenters, we performed culturing and 16S rRNA gene amplicon sequencing on samples collected from phylogenetically diverse herbivorous hosts. Using a unique approach for recovering axenic Fibrobacter cultures, we isolated 45 novel strains from 11 different hosts. Full‐length 16S rRNA gene sequencing of these isolates identified nine discrete phylotypes (cutoff = 0.03%) among them, including several that were only isolated from hindgut‐fermenting hosts, and four previously unrepresented by axenic cultures. Our phylogenetic analysis indicated that six of the phylotypes are more closely related to previously described subspecies of Fibrobacter succinogenes, while the remaining three were more closely related to F. intestinalis. Culture‐independent bacterial community profiling confirmed that most isolates were representative of numerically dominant phylotypes in their respective samples and strengthened the association of certain phylotypes with either ruminants or hindgut‐fermenters. Despite considerable phylogenetic diversity observed among the Fibrobacter strains isolated here, phenotypic characterization suggests a conserved specialization for growth on cellulose.
Corporate Governance and Tobin's Q as a Measure of Organizational Performance
Authors: Singh Satwinder , Tabassum Naeem , Darwish Tamer K. , Batsakis Georgios 
Published: July 2017

AbstractThis empirical study examines the relationship between corporate governance and organizational performance (OP), measured using Tobin's Q (TQ) in the context of an emerging economy for which, as yet, only a handful of studies have been conducted. We employ a system generalized method of moments approach controlling for endogeneity and test it on a newly created dataset comprising 324 listed firms in Pakistan. We find that board size, number of board committees and ownership concentration are positively linked with high TQ ratio, whilst board independence and CEO duality display a negative relationship. In terms of moderating effects, we find that ownership concentration negatively moderates the relationship between board independence and OP, as well as that of CEO duality and OP. The relationship between the number of board committees and OP is positively moderated by ownership concentration. Our findings contribute towards a better articulation and application of a more concrete measure of OP − that of the TQ ratio − whilst, at the same time, testing the board composition–performance relationship in the context of an upcoming and increasingly important emerging market. Wider applicability of results and policy implications are discussed.
Induction of pitting corrosion on stainless steel (grades 304 and 316) used in dairy industry by biofilms of common sporeformers
Authors: Gupta Somil , Anand Sanjeev 
Published: July 2017

This study hypothesised that there may be induction of pitting corrosion or microbially‐induced corrosion on stainless steel (SS) dairy‐processing surfaces by biofilms of common milk sporeformers such as Bacillus sporothermodurans and Geobacillus stearothermophilus. Scanning electron microscopy (SEM) and micrographs generated from energy‐dispersive spectroscopy were used to observe pitting corrosion and to find the elemental composition and distribution on the control and pitted surfaces. From SEM images and energy‐dispersive spectroscopy micrographs, it was observed that pitting corrosion on SS could be induced by biofilms of both B. sporothermodurans and G. stearothermophilus.

Published: July 2017

AbstractYeast‐mediated dough fermentation is an important phase in the bread making process. The fermentative performance of yeast cells during fermentation is of critical importance for final bread quality, since yeast cells produce CO2 and other metabolites that have an influence on dough rheology and bread texture, volume, and taste. Different factors affect the fermentative performance of yeast cells during dough fermentation, including dough ingredients, fermentation conditions, the type of yeast strain used and yeast pregrowth conditions. Bread dough is a complex matrix that contains several ingredients that can affect the fermentation rate of yeast cells. Although the individual effects of sugar availability and salt level on the leavening ability of yeast have been studied extensively, a comprehensive overview of the relationship between bread dough constituents, fermentation conditions and yeast functionality is still lacking. Moreover, the dough environment is highly variable as several types of dough like lean, sweet or frozen doughs are currently produced by commercial bread producers. For optimal fermentation rates in different types of dough, the use of appropriate yeast strains with specific phenotypic traits is required. Therefore, many researchers have focused on the improvement of yeast strains for optimal fermentation in different types of dough like lean, sweet or frozen dough. Against this background, this review summarizes the current knowledge on the interaction between bread dough and baker's yeast and how to improve this interaction, thereby providing a useful background for further research concerning the functionality of yeast in bread dough.

Authors: Wang Rong , Chan Darius Kwan Shing , Goh Yong Wah , Penfold Melissa , Harper Timothy , Weltewitz Tim 
Published: July 2017

This study investigates how humor usage (including positive and negative humor styles) influences employees' responses to the same stressful events, namely, the auto‐correlation between stress experiences at two time points. Moreover, it examines differences between Australian and Chinese employees in such effects via bicultural comparisons. Results from a two‐wave survey of 109 Australian and 141 Chinese employees indicated that humor usage moderated the StressTime1 – StressTime2 relationship for Australian employees but not for Chinese employees. Specifically, the positive relationship between the two stress measures became weaker for Australians who were higher in humor than those lower in humor. Similarly, Positive humor mitigated the relationship between StressTime1 and StressTime2 only for the Australians but not the Chinese. However, Negative humor exerted no influence on the focal relationship in either sample. Organizations should encourage employees to use humor in effective ways, thereby improving stress coping skills and reducing workplace stress.

Published: July 2017

AbstractAimThe objectives were to determine the frequency of in utero fetal death (IUFD) related to placental disorders and to assess the frequency of antiphospholipid antibodies syndrome (APS) among women referred to the internal medicine department.MethodologyA retrospective clinical study conducted in Rennes University Hospital, France. From January 2007 to December 2014, 53 women who presented an IUFD at 14 weeks or more of gestational age were included. The main cause for each IUFD was determined by expert agreement. Primary outcome was to analyze the final etiologies diagnosed and the prevalence of IUFD related to placental disorders. Secondary outcomes included the frequency of APS among patients with IUFD of placental origin and the pathological and clinical features associated with APS.ResultsIUFD resulted from placental disorders in 36/53 (68%) patients, and remained unexplained in 11 cases (20.8%). Among the 36 patients with placental disorders, APS was diagnosed in five (13.9%) cases, and four (11.1%) patients were considered as having ‘non‐criteria’ APS. History of thrombosis (P = 0.001) and placental infarcts (P = 0.047) were significantly associated with APS.ConclusionPlacental disorders were the major cause for IUFD in patients who were referred to internal medicine specialists. Importantly, APS was seldom found in patients with placental disorders. Venous thromboembolism history and placental infarcts were both significantly associated with APS. Further studies are needed in order to deepen our understanding of the physiopathology of placental disorders and its underlying causes among non‐APS women, and to determine the best treatment regimen for future pregnancies.
