Authors: Jedličková Anetta 
Published: December 2021

Abstract
The current coronavirus disease 2019 (COVID-19) pandemic has led to essential adjustments in clinical research involving human subjects. The pandemic is substantially affecting most procedures of ongoing, as well as new clinical trials related to diseases other than COVID-19. Procedural changes and study protocol modifications may significantly impact ethically salient fundamentals, such as the risk-benefit profile and safety of clinical trial participants, which raise key ethical challenges the subject-matter experts must face. This article aims to acquaint a wide audience of clinical research professionals, ethicists, as well as the general public interested in this topic with the legal, ethical and practical considerations in the field of clinical trials during the COVID-19 pandemic and to support the clinical researchers and study sponsors to fulfil their responsibilities in conducting clinical trials in a professional way that does not conflict with any legal or ethical obligations.

Authors: Berber Nemanja , Slavić Agneš , Aleksić Marko 
Published: December 2021

Abstract
Corporate social responsibility (CSR), as a concept that tackles economic, social, and environmental dimensions of business, becomes more and more implemented in companies all around the world. There are different effects that CSR can have on business performance, but it is generally accepted that CSR is related to positive outcomes in business organizations. Also, CSR is a concept that can be understood as a way of reaching sustainable development in the future. This paper aims to investigate the level of the implementation of CSR in Serbia, concerning large companies in the processing industry. The methodology used in the paper obtains exploration of theoretical sources, but also the analysis of primary empirical data gathered in Serbia, in the period from November 2019 until June 2020. The authors designed a questionnaire to explore the state of the art of CSR in Serbia, in business organizations, based on previous successful empirical research. Descriptive statistics, factor analysis, Mann-Whitney, and Kruskal Wallis tests were used to investigate the CSR on the sample of 73 large companies in Serbia’s processing industry. The analyses were made in SPSS software. The results point to the relatively high level of CSR activities in Serbian processing companies, and to the fact that modern companies understand the need of reaching more diversified goals than just economic ones in their business.
Unspoken Modernity: Bamboo-Reinforced Concrete, China 1901-40
Authors: Shu Chang-Xue 
Published: December 2021

Abstract
Engineering science in the China of 1901-40 had unique characteristics that disrupt the idea of a universal approach to its history.1 The following case study describes the ideas and trials of introducing bamboo into the seemingly globalised technology of reinforced concrete—an innovation developed across the borders of mechanical, naval, civil, and aeronautical engineering. The article showcases a way of knowing and working by twentieth century engineers that has not been fully acknowledged, and is not only a phenomenon of China. While bamboo was a complicated and somewhat marginal object for engineering, it did make the European concrete technology more viable in the construction sites of China, and stimulate engineers’ experimental and resourceful spirit in mobilising both craft and scientific knowledge. It also opened up a challenge to engineering science of the time.

Dynamic Control of Discharge Energy During WEDM for the Purpose of Eliminating Vibrations of the Wire Tool Electrode
Authors: Straka Ľuboslav , Kuchta Patrik 
Published: December 2021

Abstract
Production in all industry fields is currently affected by new scientific and technical knowledge and the requirements for its rapid deployment. In many cases, the most modern and highly sophisticated technical systems are applied. Simultaneously, fully automated production systems are rather successfully used and progressive production technologies are implemented. In most cases, there is an integral part of a management system that operates the challenging technological processes. These processes would not be executable without the system’s precise control, which provides a suitable precondition for ensuring the high quality of manufactured products. However, the customer’s demanding requirements are not always met. These involve increased requests for the quality of the final product due to the reduction of the tolerance band and application of high-strength materials. This paper aims to describe one of the solutions by which it is possible to achieve a higher quality of the machined surface after wire electrical discharge machining (WEDM). The solution proposes that through dynamic management, the WEDM process eliminates the vibrations of the wire tool electrode and thereby achieves a substantial increase in the quality of the eroded area in terms of its geometric accuracy. With the support of an extensive database of information with precise exchange of information, the proposed system will allow to control the electro discharge process with regard to the optimal way of operation of the electro discharge machine on the basis of individually selected conditions.

Published: December 2021

Abstract
Still existing scientific, technical and technological developments to improve the quality of welded joints of metal pipe structures contain contradictions and uncertainty about the effects of alloying elements, such as molybdenum, mechanical and visco-plastic properties, as well as metallographic component joints. All this indicates the need for a systematic study of these problems for the development of rational metallurgical and technological measures to significantly improve the technological and corrosion-mechanical properties of weld metal. Metallographic studies, using laboratory equipment with high identifying ability, found that the doping of weld metal with molybdenum in the amount of 0.2-0.4% causes fragmentation of ferrite-pearlite structure, including carbides Mn and Fe, and also reduces the number and size of non-metallic inclusions – sulfides, oxides and silicates. Moreover, non-metallic inclusions have a dispersed appearance, which promotes plasticization of the structure, which directly increases the viscous-plastic characteristics and resistance of the metal joints to crack formation. Based on the results of metallographic research, the optimum content in the weld metal of the alloyed element – molybdenum, which is 0.2-0.4%, is determined.
An Adaptive Control Strategy for a Low-Ripple Boost Converter in BLDC Motor Speed Control
Authors: Wang Haifeng , Zhang Haili 
Published: December 2021

Abstract
Conventional boost converters are widely used for connecting low-voltage power sources and inverters in motor control. However, a large filter capacitor bank is often used to reduce DC-link ripples that occur when an inverter is connected to a boost converter. Otherwise, significant voltage and current perturbations can impact on battery performance degradation and cause torque ripple, speed ripple and vibration in brushless DC (BLDC) motors. To suppress the converter’s DC-link ripple, this paper proposes a new control strategy for boost converter controller to generate low-ripple DC-link voltage or current at different motor speeds. In the proposed method, observers are designed to adaptively estimate the DC-link voltage and current harmonics. The harmonic terms are used as feedback signals to calculate the DC converter’s duty cycle. The entire control model is implemented on an embedded system, and its robustness is verified by simulation and experimental results that show the DC-link voltage and current ripples can be reduced by about 50% and 30%, respectively.

Published: December 2021

Abstract

Lonicera caerulea L., also known as honeysuckle berries, are rich in biologically active compounds, which makes them a valuable raw material for the development of functional foods. The objects of the research were three honeysuckle cultivars (‘Zoluška’, ‘Siņaja Ptica’, ‘Goluboje Vereteno’), four genotypes (No 2A; No 3; No 5; No 8) and kefir, enriched with various amounts (3–10%) of fruit puree. Physical and chemical analyses to determine the qualitative indicators of raw materials and products were performed. The degree of liking of kefir was assessed using sensory analysis: hedonic and line scales. The results obtained showed that among the cultivars the highest content of anthocyanins (1103.5 mg·100 g−1), total phenols (693.3 mg·100 g−1), flavonoids (753.9 mg·100 g−1), and tannins (1.6 mg·100 g−1), were found in ‘Siņaja Ptica’ berries, while among the genotypes, berries of No 8 had the highest concentration of the aforesaid compounds. Both samples also showed the highest antiradical activity: ABTS+• on average by 71.7% and DPPH− by 43.7%. According to the sensory evaluation, kefir with 10% honeysuckle puree was rated the highest. Honeysuckle berries could be used as a promising source of natural anti-oxidants in future research aimed at developing different new products that could meet consumer expectations.

Authors: Leslie Katie F , Probst M. Kate , Hawkins Taylor L 
Published: December 2021

Introduction: The purpose of this mixed-methods study was to evaluate an interprofessional academic-practice partnership in end of life care by examining patient medication outcomes, the contributions of student pharmacists and a pharmacy preceptor to care teams, and student learning experiences.
Methods: Retrospective chart review assessed polypharmacy differences in hospice patients with a primary terminal diagnosis of non-Alzheimer’s dementia between two patient groups; Group 1 managed on interprofessional care teams within the pharmacy partnership, and Group 2, managed on teams without a pharmacist. Team members who interacted with student pharmacists and the pharmacy preceptor participated in semi-structured key informant interviews to document perceptions of pharmacy contributions to care teams and the organization. At the end of their APPE, students completed reflective writings regarding their learning.
Results: Patients in Group 1 were on statistically significant fewer medications than Group 2 at both week 4 and weeks 7-12 following admission. Five conceptual themes emerged from interviews: pharmacists as team medication experts, improved patient outcomes, interprofessional collaboration, patient/caregiver trust in medication regimens, and desire for sustainability. Student reflections included the following learning themes: teamwork, respect, value, and patient-centered care.
Conclusions: The addition of a pharmacist on interprofessional care teams decreased the average number of medications in the non-Alzheimer’s end of life patient population. Team members identified value-added contributions of student pharmacists and the pharmacy preceptor that enhanced team efficiency and patient care. Student pharmacists recognized these contributions and the experience served as an exemplar of interprofessional practice.

Published: December 2021

Background:
Meningioma is one of the most common neoplasms of the central nervous system. Multiple meningiomas without neurofibromatosis are not a usual occurrence. Intraventricular meningioma with spinal meningioma is rare and not been reported in the literature.

Case Description:
We report a case of a 63-year-old male with the left trigonal and spinal meningioma. Both the meningiomas were resected in different settings. The histological examination of tumors revealed to be of varied histology, that is, meningothelial and atypical meningioma, respectively.

Conclusion:
Although various cases with multiple cranial and spinal meningiomas are described, this is the first case of an intraventricular and spinal meningioma. With varied histology, the case also reaffirms the theory of polyclonal origin of multiple meningiomas.

The Narrative Aesthetics of Protest Images
Authors: Fasnacht Hannah 
Published: December 2021

In this paper I argue that protest images have a certain aesthetics and a degree of transformative power. Crucial to this aesthetics is the images’ narrative structure, like the representation of goal-directed actions. On this basis, I show that there are more aspects that contribute to the storytelling capacity, like narrative characteristics and an aesthetics of dramatization. Using the example of climate change protests as a case study, I establish that these aspects can contribute to the transformative ability of protest images, if used effectively.
