Published: May 2020

Nos últimos 20 anos cresce no mundo todo o interesse pela produção agrícola, para fins alimentícios ou não, em áreas urbanas ou periurbanas – Agricultura Urbana. Contribuem para esse movimento a preocupação da sociedade e dos formuladores de políticas públicas de desenvolvimento local e regional com a ocupação de espaços ociosos, com a ampliação de áreas verdes, mitigação de enchentes e de ilhas de calor nas metrópoles, com a intensificação da demanda de alimentos e com as mudanças no modo de produzir e consumir alimentos saudáveis e funcionais. Aos benefícios vinculados ao planejamento da ocupação urbana e ao bem-estar da população somam-se benefícios socioeconômicos, como a utilização de mão de obra e insumos disponíveis no entorno ou dentro da área urbana e a redução dos custos de logística mediante a proximidade entre produtores e consumidores e a consequente redução no uso de combustíveis fósseis, contribuindo para a sustentabilidade do sistema produtivo. A Agricultura Urbana compreende alimentos de origem vegetal ou animal, sejam produzidos de forma convencional, sofisticada ou exclusiva (como brotos, micro verdes e mini hortaliças), plantas ornamentais e para extração de fármacos. A produção vegetal pode ocorrer tanto ao ar livre como em ambientes protegidos, no solo ou por meio do cultivo intensivo, com ou sem substratos, com ou sem luz artificial, ou ainda com diferentes níveis de automação e controle ambiental, através do monitoramento de temperatura e uso desumidificadores para manutenção da sanidade vegetal. Além disso, ela precisa atentar à economia de água e insumos, para obter maior eficiência energética. A Agricultura Urbana também pode proporcionar maior contato das pessoas com a natureza e incorporar atividades educacionais e terapêuticas. Porém, a transferência dos sistemas de produção agrícola do campo para a área urbana pode exigir soluções tecnológicas específicas, com diferentes níveis de complexidade e estratégias competitivas e organizacionais, visando à sustentabilidade dos novos modelos de negócio (Indústria 4.0) e de planejamento urbano. Por conseguinte, o objeto deste artigo é identificar as demandas tecnológicas da agricultura urbana, quanto à produção intensiva de plantas em ambientes altamente controlados, tendo em vista a eficiência do sistema produtivo, quanto à sua produtividade, qualidade e rentabilidade, por meio de análise diagnóstica, através de dados secundários e entrevistas com agentes-chave na cadeia produtiva.Palavras-chave: Inovações tecnológicas.

Published: May 2020

Abstract
Swine respiratory diseases represent one of the most frequent health issues in pig production worldwide. Despite the great progress that has been made in the field of diagnostics, control and prophylaxis, respiratory diseases still remain the most challenging health problem in modern commercial pig production. The list of infectious agents that cause respiratory diseases in swine is extensive and includes both, bacterial and viral pathogens. In Serbia, more than fifteen years after the introduction of modern vaccines, the list of bacterial pathogens related to swine respiratory infections still include Mycoplasma hyopneumoniae, Actinobacillus pleuropneumoniae, Haemophilus parasuis and Pasteurella multocida. On the other hand, most commonly involved viral pathogens are Porcine Reproductive and Respiratory Syndrome Virus, Swine influenza virus, Porcine circovirus type 2 and Pseudorabies virus. The morphological features of pneumonia where several agents are involved, depend on the predominant etiological agent. Expanding knowledge of the main pathogens associated with swine respiratory diseases and the effects of their interactions on the disease outcome is important for further investigations of lung diseases and implementation of control strategies in commercial pig populations in Serbia. This review discusses the latest findings on swine respiratory disease and current trends in Serbian pig production.
Analogue Modelling of Flow Patterns in Bobbin Friction Stir Welding by the Dark-Field/Bright-Field Illumination Method
Authors: Tamadon A. , Pons D. J. , Clucas D. 
Published: May 2020

Abstract
The flow-inducing effect of the bobbin-tool features (tri-flat pin and scrolled shoulder) were replicated by a simple analogue model for aluminium welds by layered plasticine samples. Flow patterns of the weld zone were clarified by a typical stereomicroscopy instrument assisted by dark-field/bright-field illumination. The effects of the pin features, specifically threads and flats in centre of bond zone and scrolled shoulder in sides of stirred zone, were identified. This study shows that internal flow features for BFSW welds is transferable from the friction stir welding process to the functional metal forming processes such where the shearing can extensively affect the microstructure. The similarity between the flow pattern of the provided aluminium samples and the plasticine analogue can validate the accuracy of the flow model presented in this work.
Effects of Co2 and Nd:YAG Laser Remelting of the Ti6Al4V Alloy on the Surface Quality and Residual Stresses
Authors: Jażdżewska M. 
Published: May 2020

Abstract
The titanium alloys are materials susceptible to tribological wear and the laser treatment can be applied in surface treatment processes to obtain for example higher hardness level. From the other side, it is important to take into consideration, that hardness increase that can be connected with cracks. The aim of this research was to investigate the effects of different lasers and the process parameters on the form and level of residual stresses in the Ti6Al4V alloy, which determine the initiation and propagation of cracking. Two lasers were used, the CO2 and Nd:YAG lasers. The specimens were remelted in liquid nitrogen, water or calm air at different pre-heating temperature. The different laser power and scan rates were applied. The increase in energy density increased the number of cracks, the change of an environment and pre-heating affected alo the surface cracking. The cracks observed after remelting with Nd:YAG laser were longer than those observed after treatment with CO2 laser. The compressive stresses after the CO2 laser treatment, and tensile stresses after treatment with the Nd:YAG laser, were found. The appearance of cracks was attributed to an excessive energy density. The different distribution of heat energy inside and around the laser tracks was discussed as the origin of presence either tensile or compressive stresses in the alloy treated with different lasers.

A batch and cloud point extraction kinetic spectrophotometric method for determining trace and ultra trace amounts of Benzodiazepine drugs (Clonazepam and Nitrazepam) in pure and pharmaceutical preparations
Authors: Mahdi Muna Iskandar , Kadhim Kassim Hassan 
Published: May 2020

Abstract
Utilizing the batch Diazotization coupling reaction and the cloud point extraction kinetic spectrophotometric method, trace and Ultra trace amounts from reducing Nitrazepam and Clonazepam were evaluated by way of using 2,5-dimethoxyaniline as a new Chromogenic reagent to give colored products (red) in acidic medium which have a maximum absorption at 500 and 502 nm, respectively. In the work, the analytical data of batch and cloud point for Nitrazepam and Clonazepam depended on initial rate and fixation time. This involved concentrations of (0,3-9), (0.05-1.2), (0.5-10) and (0.025-1) µg mL−1, as well as molar absorptivity of (3.8×104), (3.1×105) (3.39×104) and (3.47×105) L mol−1 cm−1. According to our results, Sandall’s sensitivity were (0.0074), (0.0009), (0.0092) and (0.0009) µg cm−2, while detection limits were (0.055) and (0.069) µg mL−1, (8.4) and (8.5) ng mL−1. In addition, the measurements enrichment factors were (33.33) and (50), while preconcentration factors were (8) and (9.9), respectively. The reaction of Nitrazepam and Clonazepam with 2,5-dimethoxyaniline were a pseudo first order according to kinetic studies. The proposed methods are not affected by existence of excipients so the methods can be applied successfully for determination of Nitrazepam and Clonazepam in pharmaceutical preparations.

Published: May 2020

Abstract
Despite a fairly large amount of literature data about the involvement of hydrogen sulfide in physiological and pathophysiological processes, its role in gastrointestinal tract functioning has not been studied sufficiently. This review systematizes and generalizes the mechanisms of H2S-associated regulation of gastrointestinal secretion and motility on the basis of literature sources processing and own research results. We analysed world professional literature and sources in Google Scholar, PubMed, MedLine, Embase, Cochrane, and data from more than 50 articles and books on the problem were processed in the article. This review gives a synopsis of the H2S function in the regulation of the secretory and motor-evacuation function, and in stimulating the reparative properties of the digestive tract, and indicates the main mechanisms.

Published: May 2020

Abstract
In this study, methanolic crude extracts of Stephania japonica (Thunb.) Miers. (MESJ) whole plants were examined for possible antidepressant and sedative-hypnotic activities. Herein, the forced swimming test and tail suspension test were conducted to explore the antidepressant activity. In addition, the open field test and hole-board test were performed to evaluate the sedative-hypnotic activities. In the acute toxicity test, the MESJ ensured safety up to a dose of 2000 mg/kg, p.o. The experimental doses were 100 and 200 mg/kg p.o. In both the forced swimming test and tail suspension test, the extract significantly (p<0.01 and p<0.05) inhibited immobility time in a dose dependent manner compared to the control. These results (13.56-26.46% inhibition) indicate the mild antidepressant activity of MESJ compared to nortriptyline (60.4-64.6% inhibition). The open field test and hole-board test demonstrated the dose dependent significant (p<0.001, p<0.01 and p<0.05) and moderate sedative-hypnotic activities of the extract compared to diazepam. However, these activities were found to gradually decrease after 60 min in the open field test and must be considered as short-term activities, compared to diazepam. It can be claimed that the methanolic crude extract of Stephania japonica possesses mild antidepressant and moderate but short-term sedative-hypnotic activities.

Authors: Cooke Lesley Anne , Jackson Hester , Armoed Zakheeya 
Published: May 2020

Abstract
The research reported in this paper is part of a large Personalised Engineering Education South Africa III Project that involves eight universities across Europe and South Africa. One of the foci of the project is around gender equality in engineering education. The literature on Women in Science, Engineering and Technology (STEM) in general is briefly reviewed. Attention then shifts to gender equality in STEM, academia, and engineering education more specifically. Management Information data from 2014 to 2018 were analysed to establish a baseline for the number and the rank of female staff in seven academic departments in the Faculty of Engineering and the Built Environment (EBE) at Durban University of Technology (DUT). The results show that there is low representation of female staff in the selected academic departments. Female staff are not represented in the higher academic ranks such as Associate or Full Professors. These findings resonate with other published research. This baseline study will be used to further investigate the experiences of women in EBE at DUT.

Collaborative Service-Learning Partnerships between Government, Community and University for Implementing Social Change
Authors: Scheepers Jacqueline 
Published: May 2020

Abstract
Community Engagement, the third pillar of Higher Education, requires South African universities to engage in projects that benefit society. Service-Learning, a form of community engagement, is a powerful pedagogical tool that lends itself to the enrichment of diversity and conceptualisation of innovative curriculum activities towards the positive transformation of students, academic staff and the broader society. Meaningful government and community partnerships are assets for universities who strive for relevant engagement with communities. In Service-Learning triad partnerships, the government, university and community stakeholders collaboratively conceptualise Service-Learning projects. These partnerships are composed of representatives from diverse institutional cultures and individual backgrounds. Through Participatory Action Research (PAR), the systems approach is applied to understand and critically examine the interconnectedness between the aims and objectives of government, community and the university. Service-Learning partnerships can be viewed as a powerful tool for actualizing community development strategies; moving these from policy to implementation in communities. This paper encourages universities to build meaningful partnerships with external stakeholders through service-learning projects. By engaging actively with their partners, universities could strengthen their Service-Learning initiatives and partnerships.

Authors: Czerniachowicz Barbara , Wieczorek-Szymańska Anna 
Published: May 2020

Abstract
The aim of the paper is to identify university’s activities and characteristics that enable it to reorient itself towards the idea of an entrepreneurial university. In the modern world, universities have an additional important role, that is, the need to adopt entrepreneurial strategies without disrupting the quality of teaching and research. First of all, the authors discuss the idea of entrepreneurship and focus mainly on academic entrepreneurship. The idea of entrepreneurship is becoming more and more desirable in a modern organization thus also in a university. The new role of the university is to create the entrepreneurial ideas and attitudes among students and all university employees, as well as to initiate entrepreneurial activities in academic institutions. It is also necessary to plan entrepreneurial university architecture. The article focuses on presenting the theoretical foundations of the academic entrepreneurship process to finally make a synthetic comparison of the features of a traditional university and an entrepreneurial university. The main research question of the article is: In which dimensions the idea of an entrepreneurial university can lead to the development of the university?
The result of the research is a new combination of attributes and characteristics of an enterprising university and new directions of university’s development. By this paper the authors take part in the discussion about the implementation of the idea of entrepreneurship in contemporary university management.
