Abstract
Background: Salmonella species and Escherichia coli (E. coli) are important foodborne pathogens affecting humans and animals. They are among the most important causes of infection that are associated with the consumption of contaminated food. This study was aimed to determine the prevalence, antimicrobial susceptibility patterns and associated risk factors for Salmonella species and E. coli in raw meat from butchery houses of Mekelle, Northern Ethiopia.MethodA cross-sectional study was conducted from January to December 2019. Socio-demographic data and risk factors were collected using a predesigned questionnaire. Meat samples were collected aseptically from the butchery houses and transported using icebox to Mekelle University, College of Veterinary Sciences for the isolation and identification of Salmonella species and E. coli. Antimicrobial susceptibility patterns were determined using Kirby disc diffusion method. Data obtained were cleaned and entered into Statistical Package for the Social Sciences version 22 and logistic regression models with odds ratio were calculated. P-value < 0.05 was considered as statistically significant.ResultsA total of 153 out of 384 (39.8%) of the meat specimens were found to be contaminated. The contamination of Salmonella species and E. coli were 15.6% (n=60) and 20.8%) (n=80), respectively. Mixed contamination (Salmonella species and E. coli) was observed in 13 (3.4 %) of the analyzed. Poor washing hands regularly (AOR = 8.37; 95% CI: 2.75-25.50) and not using gloves during meat handling (AOR=11. 28; 95% CI: (4.69‑27.10) were associated with an overall bacterial contamination About 95.5% of the tested isolates were sensitive to chloramphenicol and norfloxacin while the resistance of amoxyclav_amoxicillin and erythromycin were both isolated bacteria species. The overall multidrug resistance pattern for Salmonella and E. coli were 51.4% (n=19) and 31.8% (14), respectively.ConclusionOf the 153 (153/384) contaminated raw meat, 60 (15.6%) and 80 (20.8%) were contaminated by Salmonella species and E. coli, respectively. Poor handwashing practice and not using glove during meat handling showed significant association with bacterial contamination. Multidrug-resistant showed in Salmonella species and E. coli were 19 (51.4%) and 14 (31.8%), respectively.

Published: June 2020

Abstract
Data representation and prediction model design play an important role in mid- to long-term runoff prediction. However, it is challenging to extract key factors that accurately characterize the changes in the runoff of a river basin because of the complex nature of the runoff process. In addition, the low accuracy is another problem for mid- to long-term runoff prediction. With an aim to solve these problems, two improvements are proposed in this paper. First, the partial mutual information (PMI)-based approach was employed for estimating the importance of various factors. Second, a deep learning architecture was introduced by using the deep belief network (DBN) with partial least-squares regression (PLSR), together denoted as PDBN, for mid- to long-term runoff prediction, which solves the problem of parameter optimization for the DBN using PLSR. The novelty of the proposed method lies in the key factor selection and a novel forecasting method for mid- to long-term runoff. Experimental results demonstrated that the proposed method can significantly improve the effect of mid- to long-term runoff prediction. Also, compared with the results obtained by current state-of-the-art prediction methods, i.e., DBN, backpropagation neural networks, and support vector machine models, our prediction results demonstrate the performance of the proposed method.
A varying comprehensive hydropower coefficient for medium/long-term operation of a single reservoir
Authors: Gong Wenting , Liu Pan , Cheng Lei , Li He , Yang Zhikai 
Published: June 2020

Abstract
In medium/long-term reservoir operation, the hydropower output is calculated from k × q × h, where q is the power discharge, h is the water head, and k is the comprehensive hydropower coefficient. k indicates the conversion efficiency from water power to electricity, however, it is standard practice to use a constant k. We developed a novel method to derive the varying k based on observed big data. The operational frequencies of different units for time (multiple periods) and space (multiple units) were accounted based on the observed big data from each unit, and then weights were obtained. Finally, k was derived by integrating the efficiency curves (hill charts) of the different units with their weights. The Three Gorges Project, China, was selected for a case study. Results indicated that: (1) the varying k value can improve hydropower simulation accuracy, (2) simulations using 10-day intervals have a higher accuracy for hydropower calculation than daily and monthly scales, (3) the evaluation of hydropower plant benefits is sensitive to k, and there is potential for producing more hydropower. These findings are highly relevant to the operation of hydropower plants and to the evaluation of medium/long-term hydropower generation for a hydropower plant.

Authors: Slavik Irene , Oliveira Keila Roberta , Cheung Peter Batista , Uhl Wolfgang 
Published: June 2020

Abstract
In many parts of the world, drinking water storage takes place in near-house or in-house tanks. This can impact drinking water quality considerably. International and numerous national standards and guidelines addressing the construction, installation and operation of domestic drinking water storage tanks are reviewed on their consideration of water quality aspects and the minimisation of health risks associated with drinking water storage. Several national and international standards and guidelines are reviewed in terms of drinking water quality requirements. Factors that have an impact on water quality in relation to the use of domestic drinking water storage tanks are summarised comprehensively. The impact of the domestic storage of drinking water on water quality, the points and locations of use, their positioning, the materials they are made of, their design and operation, as well as aspects of how they are operated and maintained is outlined and discussed in detail. Finally, the incorporation of aspects regarding water quality in drinking water storage tanks in standards and guidelines is presented and assessed. To make the use of domestic drinking water storage tanks safer and more efficient, recommendations for modifications, improvements and extensions of respective standards are made.

Abstract
As organic dyes are the main pollutants in water pollution, seeking effective removal solutions is urgent for humans and the environment. A novel environmentally friendly three-dimensional CoFe-LDHs (3D CoFe-LDHs) catalyst was synthesized by one-step hydrothermal method. Scanning electron microscopy, energy dispersive spectroscopy, Fourier transform infrared spectra, X-ray diffraction, X-ray photoelectron spectroscopy, Brunauer-Emmett-Teller technique as well as UV-Vis diffuse reflectance spectra were used to characterize the prepared samples. The experimental results revealed that 3D CoFe-LDHs exhibited a rapid decolorization of methyl orange and Rhodamine B by heterogeneous photo-Fenton process after reaching the adsorption equilibrium, and the final decolorization efficiency reached 91.18% and 93.56%, respectively. On the contrary, the decolorizing effect of 3D CoFe-LDHs on neutral blue was relatively weak. The initial concentrations of azo dyes, pH and H2O2 concentration affected the decolorization of dyes and the catalyst maintained excellent reusability and stability after reuse over five cycles. The quenching experiments found that •OH, •O2− and h+ were the main active substances and reaction mechanisms were further proposed. The study suggests that the synergistic effect of photocatalysis and Fenton oxidation process significantly improved the removal of azo dyes and the synthesized catalyst had potentially promising applications for difficult-to-biodegrade organic pollutants in wastewater.
Preoperative Circulating MiR-210, a Risk Factor for Postoperative Delirium Among Elderly Patients with Gastric Cancer Undergoing Curative Resection
Authors: Chen Yun , Zheng Jinwei , Chen Junping 
Published: June 2020

Background:
Postoperative delirium (POD) is a very common complication in elderly patients with
gastric cancer (GC) and associated with poor prognosis. MicroRNAs (miRNAs) serve as key post-transcriptional
regulators of gene expression via targeting mRNAs and play important roles in the nervous system. This study
aimed to investigate the potential predictive role of miRNAs for POD.

Methods:
Elderly GC patients who were scheduled to undergo elective curative resection were consequently
enrolled in this study. POD was assessed at 1 day before surgery and 1-7 days after surgery following the guidance
of the 5th edition of Diagnostic and Statistical Manual of Mental Disorders (DSM V, 2013).
The demographics, clinicopathologic characteristics and preoperative circulating miRNAs by quantitative reverse
transcription-polymerase chain reaction (qRT-PCR) were compared between patients with or without POD. Risk
factors for POD were assessed via univariate and multivariate logistic regression analyses.

Results:
A total of 370 participants were enrolled, of which 63 had suffered from POD within postoperative 7
days with an incidence of 17.0%. Preoperative miR-210 was a predictor for POD with an area under the curve
(AUC) of 0.921, a cut-off value of 1.67, a sensitivity of 95.11%, and a specificity of 92.06%, (P<0.001). In the
multivariate logistic regression model, the relative expression of serum miR-210 was an independent risk factor
for POD (OR: 3.37, 95%CI: 1.98–5.87, P=0.003).

Conclusions:
In conclusion, the present study highlighted that preoperative miR-210 could serve as a potential
predictor for POD in elderly GC patients undergoing curative resection.

Published: June 2020

Background:
The impact of infectious agents, such as Toxoplasma gondii (T. gondii),
on human behavior and mental disorders, has recently attracted the attention of researchers. T. gondii
has emerged as a suitable candidate for such disorders due to its neutral nature. Therefore, the
current study aimed at investigating the possible relationship between T. gondii infection and headache.

Methods:
Five databases were thoroughly searched (up to October 4, 2019) for articles on the prevalence
of T. gondii in headache sufferers. In this study, the odds ratio (OR) and corresponding
95% confidence interval (CI) were estimated using a random effect model and forest plot to gauge
effect size and effect of each study.

Results:
A total number of four articles, including one cross-sectional and three case-control
studies 2517 participants, entered the meta-analysis, out of whom, 1205 subjects were afflicted
with headache or migraine (17.67% positive for toxoplasmosis) and 1312 participants were not
(18.29% for toxoplasmosis). The results of the meta-analysis indicated a common OR of 1.59
(95% CI: 1.03-2.47) by the random effect model.

Conclusion:
The obtained results of several studies have linked toxoplasmosis and headache.
Therefore, more quality studies with larger sample sizes are needed to determine the detailed association
between headache and T. gondii infection for the prevention and control of toxoplasmosis
among headache sufferers.

The purpose of this article is to link the assessment of the key evidentiary elements, which are demostrative o the existence of the so called periculum in mora into the complex meaning of circumstantial evidence. If prison on remand is adopted by the judge on the basis of a presumption, which builds on circunstancial evidence, that decision reveals the cautionary risks that justify it, so there is not arguments for not aplying the elements of that kind of evidence to judicial reasoning.

SIX DEGREES OF CHEM & BACON
Authors: Robinson Mary , Minshull Scarlett 
Published: June 2020

Some courses are just not of interest to some students but are nonetheless important to their education as engineers. First-year chemistry for engineers has been shown to be one such course; student exit surveys at graduation indicate that students from some programs didn’t see how the course connected to their program or into their careers as engineers [1]. Gamification is a popular technique where game elements, like point systems, are integrated into a course structure to motivate student learning and participation [2]. In the offering of this first-year chemistry course in the summer of 2019, the instructor applied gamification techniques in the course design. The major changes to the course structure included the ability to “unlock” an alternate grading scheme if at least five of seven tasks were completed, at least three of which were the completion of a “Six Degrees of Chem & Bacon” challenge. These challenges required the students to think about a core topic in the course module and find a practical application from their discipline of engineering. The experiences of the instructor and a student in the Spring 2019 class are shared here. The big take-aways are 1) to consider the benefits of reflection in learning, and 2) to consider the workload, both of the students and of the teaching team, when adding this type of activity to a course.
THE ROLE OF SUB-DISCIPLINE CHOICE IN WOMEN’S ENROLLMENT AND SUCCESS WITHIN CANADIAN UNDERGRADUATE ENGINEERING PROGRAMS.
Authors: Sweeney Juliette 
Published: June 2020

In Canada, the proportion of female students in engineering is considerably lower than the proportion of female students in higher education. Using Tinto’s (1993) theories concerning social and academic integration, this study investigated the relationships between the proportion of female undergraduate engineering students, and the proportion of female faculty, and departmental lead faculty. Using descriptive statistics, the study established that distinct and persistent differences exist in the proportions of female enrolment among schools and among sub-disciplines. This paper addresses a gap in the literature concerning the impact of sub-discipline choice on women's engagement and success within undergraduate engineering programs in Canada. The proportion of female students was found to vary considerably across the sub-disciplines, from 48% in biosystems to 15% in software engineering [14]. The paper will present female sub-discipline enrolment trends over time and discuss the impact of sub-discipline choice and institutional factors on female students' successful academic and social integration within Canadian engineering schools.
WHO YOU ARE AND HOW YOU WORK: EMBEDDING POSITIONALITY IN ENGINEERING DESIGN
Authors: Walji Noosheen , Sheridan Patricia K. , Kinnear Penny , Irish Robert , Foster Jason 
Published: June 2020

As the Engineering profession increasingly explores the complex relationships between technology and society, the responsibility of engineers is evolving to include considering the socio-technical complexities in which their technology will be embedded [1]. This evolution has led to interest in teaching empathy and reflexivity in undergraduate engineering education, in part to prepare student engineers for effective community engagement in their engineering practice [2] [3]. This practice paper discusses considerations, approaches, and theories that informed our design practice as we incorporated positionality into our course. Positionality was introduced as a foundational design tool to approximately 300 students in a first-year design course at a large, public, research-intensive university. In this work we discuss the integration of positionality as a framework to facilitate self-awareness, intentionality, leadership, reflexivity, and empathy in individual and team engineering design activities.
Clinical and epidemiological analysis of severe traumatic brain injury: the role of nutritional support to the injured with a prolonged state of impaired consciousness
Authors: Nikiforov M. V. , Korolev A. A. 
Published: June 2020

Relevance. Patients with prolonged impaired consciousness due to traumatic brain injury are the most difficult category of patients in inpatient medical rehabilitation units. Despite the experience gained in managing this complex category of patients, the problem of nutrition status and trophological insufficiency, as well as practical issues regarding the organization of optimal nutrition at this stage of medical rehabilitation remain unresolved.Intention. To study the role of nutritional support for patients with long-term impaired consciousness on the basis of a clinical and epidemiological analysis of severe traumatic brain injury.Methodology.The data of an epidemiological analysis of traumatic brain injuries and features of ongoing nutritional support in patients with long-term impaired consciousness are presented, based on a study of domestic and foreign publications from 2005 to 2019.Results and Discussion. Timely and adequate nutritional support optimizes the structural-functional and metabolic systems of the body, adaptive reserves interfere with rapidly progressive depletion and chronic catabolic processes, contribute to positive changes in the functional state of the brain, reduce infectious complications, and increase the effectiveness of rehabilitation measures and the rate of recovery of consciousness.Conclusion. The analysis revealed the ambiguity of the interpreted data on clinical recommendations and approaches to the use of nutritional support in patients with long-term impaired consciousness due to traumatic brain injury. Considering the fact that in most cases such patients need continuous long-term comprehensive rehabilitation measures, accompanied by significant energy costs of the body, an essential component of the rehabilitation process, in our opinion, is the inclusion of adequate nutritional support that prevents fast-progressing exhaustion and chronic catabolic processes. In this regard, such an urgent task is to optimize the algorithms of nutritional support in patients with long-term impaired consciousness after a traumatic brain injury, the solution of which will improve the functional state of the brain and, therefore, the rehabilitation prognosis and quality of their life.
Corpo e contexto escolar: experiências lúdico-simbólicas

Published: June 2020

Este artigo trata de um estudo do imaginário lúdico através do movimento corporal de crianças de uma escola pública, localizada na cidade de Niterói/RJ. Pretendeu-se construir uma pesquisa dos sentidos, com vistas a trazer à tona reflexões sobre a tensão entre a potência das manifestações corporais e os fazeres docentes revelados na dinâmica lúdico simbólica das crianças, em atividades de jogos e brincadeiras. O estudo se fundamentou na perspectiva teórico-metodológica da sociologia compreensiva de Michel Maffesoli e na teoria da complexidade de Edgar Morin. Os estudos do imaginário, os estudos sobre corpo, e a pesquisa narrativa, alinharam-se ao referencial teórico-metodológico, de modo a capturar os sentidos dos espaços revelando a cultura das crianças (modos de pensar, sentir e agir), pela expressividade de suas múltiplas linguagens, especialmente a linguagem corporal. Por meio da cartogênese, uma das heurísticas utilizadas para capturar manifestações simbólicas, foi revelado que a linguagem corporal das crianças do estudo remetem à heroicidade e ao afeto. Acreditamos que a pesquisa mostrou que a saída para a crise atual do paradigma dominante será o aparecimento de um novo paradigma, que não negue o anterior, mas que transforme o ‘olhar’ do homem para a realidade dada; que não exclua a emoção, a beleza, a ética e a estética e, sobretudo, o corpo que, por imagens simbólicas, expressa sentimentos, emoções e formas de ser e estar no mundo.
