Abstract
The concrete-filled steel tubular (CFST) arch is a new high-strength support form for a mine roadway in deep/soft rock stratum; however, the bearing characteristics have not been clearly elucidated for scientifically guiding field applications. Numerical simulation tests with 15 schemes shaped as a ‘half circle with two straight legs’ and 10 schemes shaped as a circle were conducted, and the main responses of the numerical model were verified by performing the laboratory tests to evaluate the basic CFST structures and global CFST arches. The bearing and failure behaviors of the CFST arches were studied, and the influence laws, in terms of the arch shape, size and lateral pressure coefficient λ, were further investigated. The results show that the bearing capacity of a circular arch is significantly higher than that of a straight-leg arch under a uniform load. Furthermore, the bearing capacity of the circular arch decreases considerably with the increase in the arch size or λ. In addition, the bearing capacity of a straight-leg arch decreases with the increase in the leg height and arch size; however, it first increases and later decreases with the increase in λ. The failure modes of all the arches correspond to the instability at the extreme point caused by the strength deterioration, except in the case of a circular arch under a uniform pressure, the failure mode of which corresponds to the instability at the branch points. Finally, the recommendations for the field practice are proposed and verified.
Polnische Bibliothek
Authors: Zajas Paweł 
Published: March 2020

AbstractThePolnische Bibliothek,founded by the German Institute for Polish Culture in Darmstadt, financed by Robert Bosch Foundation and published by the Suhrkamp Publishing House, remains a unique attempt at presenting Polish literature in the German book market. This paper focuses on the historical, political and cultural background of the series and the conflicts at the backstage of its initiation. The analysis, based mostly on the so far unpublished archival correspondence of the publishing house has two aims: on the one hand, a historiographic description of the so far unknown processes of Polish literature transfer lies at its centre, on the other, it addresses the need for appropriate conceptualisations of such phenomena. The study is framed in the category ofHistoire croiséein this case applied to an analysis of translation production. Activities of all the actors involved, the conflicts and solutions to them constitute the starting point. These generate an argumentation space which offers insights into the history of production of the series that had since its beginning been marked by conflicting expectations.
Carlo Antonio and the bottega Procaccini
Authors: Conte Angelo Lo 
Published: March 2020

Abstract
This study investigates the career of Carlo Antonio Procaccini, a member of one of the most prominent artistic families of the early Italian Seicento. Together with his brothers Camillo and Giulio Cesare, he was instrumental in establishing a famous workshop in Milan which played a fundamental role in the artistic renovation of the Borromean era. Celebrated by seventeenthcentury sources, Carlo Antonio’s career has been largely underestimated. The essay reaffirms his legacy as the most important North Italian landscape painter of the first three decades of the seventeenth century, highlighting how his art thrived in the uniqueness of the Milanese artistic environment, which was characterized by post-Tridentine reform and prosperity, Spanish patrons, and Northern European connections as well as artistic eclecticism.
Translating images from India to Amsterdam in the eighteenth century

Published: March 2020

Abstract
This article examines the physical interface of print and its role in translating beliefs not informed by a western theology of the imprint. A close reading of Jean Frédéric Bernard and Bernard Picart’s Cérémonies et coutumes religieuses (1723– 1743), with a focus on the section on religious practices in India, demonstrates the limitations of western typography and engraving in translating cultures formed outside of a material and physical history of the printed word and image.
Das Thema Männlichkeit im hochschuldidaktischen Verwendungszusammenhang – am Beispiel der theologischen Lehre im Fachbereich Neues Testament
Authors: Smit Peter-Ben 
Published: March 2020

Zusammenfassung
Gender ist ein wichtiges Thema in der theologischen Lehre, auch in Hochschulen. Dabei werden die Geschlechterkonstruktionen von „Männlichkeit“ häufig wenig berücksichtigt, obwohl sie großen Einfluss haben. So zeigt dieser Beitrag auf, wie Konstruktionen von „Männlichkeit“ in einem Teilbereich der Theologie, nämlich der neutestamentlichen Wissenschaft, eine bedeutsame Rolle spielen (können) und wie dies, gerade auch in der Auseinandersetzung mit Studierenden, denen diese Thematik eher fremd ist, zu einem produktiven Thema im Seminarraum gemacht werden kann, ohne dabei problematische Machtverhältnisse zu (re)produzieren.

Authors: BAMIGBOYE Rachael A. , OLOYEDE Fatai A. , AKINLOYE Akinwumi J. 
Published: March 2020

Stipe anatomy of seven Pteris species collected from various locations in the Southwestern Nigeria was investigated. This was with a view to identify characters of the stipe anatomy that are important in delimiting the species. Transverse sections (TS) of stipe at proximal median and distal regions were cut with the aid of a Reichert Austria sledge microtome at 10 µ thickness. Sections were stained in Safranin O for five minutes, rinsed in three successive changes of water and counterstained in Alcian blue for five minutes. The counterstained sections were rinsed in three changes of water, and then treated in serial grades of alcohol. Observation of prepared slides was made under light microscope. Based on the shape of the vascular bundles, the Pteris species fall into three categories which are inverted Omega, V or U shapes. The adaxial grooves varied from proximal to distal regions in all the species except in P. ensiformis where it was uniform throughout the regions.
A New Procedure for Evaluating Ground-Motion Models, with Application to Hydraulic-Fracture-Induced Seismicity in the United Kingdom
Authors: Cremen Gemma , Werner Maximilian J. , Baptie Brian 
Published: March 2020

ABSTRACTAn essential component of seismic hazard analysis is the prediction of ground shaking (and its uncertainty), using ground-motion models (GMMs). This article proposes a new method to evaluate (i.e., rank) the suitability of GMMs for modeling ground motions in a given region. The method leverages a statistical tool from sensitivity analysis to quantitatively compare predictions of a GMM with underlying observations. We demonstrate the performance of the proposed method relative to several other popular GMM ranking procedures and highlight its advantages, which include its intuitive scoring system and its ability to account for the hierarchical structure of GMMs. We use the proposed method to evaluate the applicability of several GMMs for modeling ground motions from induced earthquakes due to U.K. shale gas development. The data consist of 195 recordings at hypocentral distances (R) less than 10 km for 29 events with local magnitude (ML) greater than 0 that relate to 2018/2019 hydraulic-fracture operations at the Preston New Road shale gas site in Lancashire and 192 R&lt;10  km recordings for 48 ML&gt;0 events induced—within the same geologic formation—by coal mining near New Ollerton, North Nottinghamshire. We examine: (1) the Akkar, Sandikkaya, and Bommer (2014) models for European seismicity; (2) the Douglas et al. (2013) model for geothermal-induced seismicity; and (3) the Atkinson (2015) model for central and eastern North America induced seismicity. We find the Douglas et al. (2013) model to be the most suitable for almost all of the considered ground-motion intensity measures. We modify this model by recomputing its coefficients in line with the observed data, to further improve its accuracy for future analyses of the seismic hazard of interest. This study both advances the state of the art in GMM evaluation and enhances understanding of the seismic hazard related to U.K. shale gas development.
Transient Analysis of M[X1],M[X2]/G1,G2/1 retrial queueing system with priority services, working breakdown, start up close down time, Bernoulli vacation, reneging and balking
Authors: Ayyappan Govindhan , J Udayageetha 
Published: March 2020

This paper considers M[X1],M[X2]/G1,G2/1 general retrial queueing system with priority services. Two types of customers from different classes arrive at the system in different independent compound Poisson processes. The server follows the pre-emptive priority rule subject to working breakdown, startup/closedown time and Bernoulli vacation with general (arbitrary) vacation periods. After completing the service, if there are no priority customers present in the system the server may go for a vacation or close down the system. On completion of the close down, the server needs some time to set up the system. The priority customers who find the server busy are queued in the system. A low-priority customer who find the server busy are routed to a retrial (orbit) queue that attempts to get the service. The system may breakdown at any point of time when it is in operation. However, when the system fails, instead of stopping service completely, the service is continued only to the high priority customers at a slower rate. We consider balking to occur to the low priority customer while the server is busy or idle, and reneging to occur at the high priority customers during serverâ€™s vacation, start up/close down time. Using the supplementary variable technique, we derive the joint distribution of the server state and the number of customers in the system. Finally, some performance measures and numerical examples are presented.

Improvement of the Medical Education Situation in Sudan: Collegectomy is Not the Only Management Option
Authors: Abdalla Mohamed Elhassan , Taha Mohamed Hassan 
Published: March 2020

Sudan witnessed an increase in the number of colleges of medicine after the higher education revolution in the early 1990s. Many authors writing about medical education, both in Sudan and across the world, have described a negative correlation between the increased number of medical colleges and the quality of education provided by those colleges. Many educational leaders in Sudan are calling for action to deal with the issues arising from this great expansion of medical colleges, with opinions varying from collegectomies (closure of the colleges) to merging colleges.
Several strategies have been implemented in Canada, Iran, the Philippines and South Africa to deal with similar situations. These have included college support such as funding or technical support, changing the colleges’ educational strategies, modifying the curriculum, integrating (rather than merging) colleges, and collegectomies.
This paper outlines possible actions to be taken in response to the expansion of medical colleges in the Sudanese context. It explores the international experience with the situation in an attempt to augment the discussion with options that may help to improve medical education.

Published: March 2020

The rights of people with disabilities remain a topic that is frequently mentioned by the media, and the media is often criticised for their lack of sensitivity to this issue. The purpose of this study is to analyse the content of the news on people with disabilities in the newspapers published in Northern Cyprus, in order to determine the trends and frequencies of the news published in the newspapers and to provide data based on written documents for awareness. This research uses a descriptive survey model. In this study, the acquisition and analysis of data were conducted through content analysis from qualitative data. It has been determined that these three major circulation newspapers in Northern Cyprus have included disability and special needs news at a certain rate although it has been reported that the news about disability and special needs is rarely published and the amount of news about disabilities is relatively inadequate.
Keywords: Disabled, special needs, written press, content analysis.

Published: March 2020

BackgroundProfessional identity (PI) is a key factor behind nurses' ability to provide quality care. PI assessment requires valid and reliable tools.AimThis study aimed to translate into Persian the 9-item Macleod Clark Professional Identity Scale (MCPIS) and evaluate its psychometric properties among Iranian nursing students.MethodsIn this methodological study, SMCPIS was translated into Persian through forward–backward translation. The face and content validity of the translated scale were respectively assessed by 10 nursing students and a panel of 10 experts. Then, 171 nursing students completed MCPIS and Nurse Self-Concept Questionnaire. Collected data were used for construct validity assessment through confirmatory factor analysis and criterion validity assessment through correlation analysis. Reliability assessment was also performed through the internal consistency and the test-retest methods.FindingsConfirmatory factor analysis revealed good fit model for the scale. Criterion validity, measuring convergent validity, assessment also showed a significant correlation between the scores of MCPIS and Nurse Self-Concept Questionnaire (r = −0.2, P = .07). Cronbach's alpha and test–retest correlation coefficient were .87 and .72, respectively. Students' MCPIS scores ranged from 15 to 54 with a median of 44 (in the possible range of 9–54).ConclusionThe Persian MCPIS is a valid and reliable tool for PI assessment. Further studies are recommended to produce evidence supporting the validity and reliability of the scale.

Published: March 2020

Abstract
Background Although there have been a number of reports on urinary voiding symptoms associated with surgical interventions for gynecologic cancer and post-voiding symptoms, there have been few reports on urinary storage symptoms such as urinary incontinence (UI) and overactive bladder (OAB). The purpose of this study was to examine the rates and impact on quality of life (QOL) of urinary storage symptoms after gynecologic cancer surgery.
Methods A questionnaire survey, including Japanese-language versions of the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), Overactive Bladder Symptom Score (OABSS), and Incontinence Impact Questionnaire-7 (IIQ-7), was distributed to gynecologic cancer patients who underwent hysterectomy between 2008 and 2013.
Results Of the 145 patients analyzed, 49 (33.8%) had UI pre-surgery and 76 (52.4%) had UI post-surgery, including 34 (35.4%) first-time UI patients, with a significant difference between pre- and post-surgery. Of the 49 subjects with UI pre-surgery, 43 (87.7%) had stress incontinence, while of the 76 patients with UI post-surgery, 44 (57.1%) had stress incontinence, and 24 (31.2%) had mixed incontinence. Seven (4.8%) subjects had OAB pre-surgery, whereas 19 (13.1%) had OAB symptoms post-surgery (including 15 first-time OAB patients), with a significant difference between pre- and post-surgery. IIQ-7 scores were markedly higher for patients with mixed incontinence post-surgery than for those with stress incontinence, indicating a lower QOL. Logistic regression analysis identified the number of Cesarean sections and days of urinary bladder catheterization as risk factors for postoperative UI.
Conclusions UI and OAB rates were higher after gynecologic cancer surgery than in the general female population. The mixed incontinence rate was markedly higher post-surgery; QOL was low for such patients due to the combination of urgency and stress incontinence. Multiple Cesarean sections and urinary bladder catheterization post-surgery were risk factors for post-surgical UI.

Abstract
Background Synthesis of psychometric properties of substance use measures to identify patterns of use and substance use disorders remains limited. To address this gap, we sought to systematically evaluate the psychometric properties of measures to detect substance use and misuse. Methods We conducted a systematic review and meta-analysis of literature on measures of substance classes associated with HIV risk (heroin, methamphetamine, cocaine, ecstasy, alcohol) that were published in English before June 2016 that reported at least one of the following psychometric outcomes of interest: internal consistency (alpha), test-retest/inter-rater reliability (kappa), sensitivity, specificity, positive predictive value, and negative predictive value. We used meta-analytic techniques to generate pooled summary estimates for these outcomes using random effects and hierarchical logistic regression models. Results Findings across 387 paper revealed that overall, 65% of pooled estimates for alpha were in the range of fair-to-excellent; 44% of estimates for kappa were in the range of fair-to-excellent. In addition, 69%, 97%, 37% and 96% of pooled estimates for sensitivity, specificity, positive predictive value, and negative predictive value, respectively, were in the range of moderate-to-excellent. Conclusion We conclude that many substance use measures had pooled summary estimates that were at the fair/moderate-to-excellent range across different psychometric outcomes. Most scales were conducted in English, within the United States, highlighting the need to test and validate these measures in more diverse settings. Additionally, the majority of studies had high risk of bias, indicating a need for more studies with higher methodological quality.

Published: March 2020

Abstract
Background:
The design and internal layout of modern operating rooms (OR) are influencing the surgical team’s collaboration and communication, ergonomics, as well as intraoperative hygiene substantially. Yet, there is no objective method for the assessment and design of operating room setups for different surgical disciplines and intervention types available. The aim of this work is to establish an improved OR setup for common procedures in arthroplasty.
Methods
With the help of computer simulation, a method for the design and assessment of enhanced OR setups was developed. New OR setups were designed, analyzed in a computer simulation environment and evaluated in the actual intraoperative setting. Thereby, a 3D graphical simulation representation enabled the strong involvement of clinical stakeholders in all phases of the design and decision-making process of the new setup alternatives.
Results
The implementation of improved OR setups reduced the instrument handover time between the surgeon and the scrub nurse, the travel paths of the OR team as well as shortened the procedure duration. Additionally, the ergonomics of the OR staff were improved.
Conclusion
The developed simulation method was evaluated in the actual intraoperative setting and proved its benefit for the design and optimization of OR setups for different surgical intervention types. As a clinical result, enhanced setups for total knee arthroplasty and total hip arthroplasty surgeries were established in daily clinical routine and the OR efficiency was improved.

Abstract
Background: Understanding pathogenic mechanisms is imperative for developing novel treatment to the tuberculosis, an important public health burden worldwide. Recent studies demonstrated that host cholesterol levels have implications in the establishment of Mycobacterium tuberculosis ( M. tuberculosis , Mtb ) i nfection in host cells, in which the intracellular cholesterol-mediated ATP-binding cassette transporters (ABC-transporters) and cholesterol acyltransferase1 (ACAT1) exhibited abilities to regulate macrophage autophagy induced by Mycobacterium bovis Bacillus Calmette–Guérin (BCG).
Methods: In the present report, the involvements of ABC-transporters and ACAT1-mediated intracellular cholesterol in autophagy of bovine alveolar macrophages induced by Mycobacterium bovis BCG were interrogated by enzymatic and biochemistry assays in vitro, including quantitative RT-PCR and immunoblotting assays.
Results: The results showed that a down-regulated expression of the ABC-transporters and ACAT1 in primary bovine alveolar macrophages (AMs) and murine RAW264.7 cells in response to BCG infection. The inhibited expression of ABC-transporters and ACAT1 was associated with the reduction of intracellular free cholesterol, which in turn induced autophagy in macrophages upon to the Mycobacterial infection. These results strongly suggest an involvement of ABC-transporters and ACAT1 in intracellular cholesterol-mediated autophagy in AMs in response to BCG infection.
Conclusion: This study thus provides an insight into into a mechanism by which the cholesterol metabolism regulated the autophagy in macrophages in response to mycobacterial infections .
