Authors: Joseph Seena , Thompson Robyn , Soobramoney Subashnie , Wing Jeanette Wendy
Published: May 2022

The COVID-19 pandemic created the need for a global change in tertiary education. Universities that traditionally relied on contact with students in physical classrooms were forced to consider modes of remote teaching to mitigate the risks of infection due to physical proximity. This study evaluates the emergency remote teaching implemented within the Department of Information Technology at the Durban University of Technology, South Africa. An emergency remote teaching model with four stages consisting of: preparation, synchronous and asynchronous teaching and learning, e-assessments and reflections are described, analysed and evaluated with reference to both lecturers and students. The evaluation is performed using both qualitative and quantitative research methods. Qualitative analysis was performed on 29 sources using content analysis. 229 initial codes were identified and first categorized into 13 subcategories and finally to the four categories synonymous with the adopted four-stage emergency remote teaching model: preparation (135 references), asynchronous and synchronous teaching and learning (67 references), e-assessments (25 references) and reflections (8 references). Quantitative data on the use of the learning management system from 2019 to 2020 evaluated the results of the applied changes in practice. From the results, it was evident that students and lecturers invested much time in the learning management system with 13 tools being adopted by the 49 analysed subjects. The learning management system was used extensively for communication, assessment and dissemination of subject content. The comparative results of the data from the 2019 and 2020 academic years showed that the majority of the 2020 subjects’ final results were statistically higher than the 2019 results. Results of analysis revealed the success of the implementation of the four-stage emergency remote teaching model.

Revealing invisibility: Interpreting social and behavioral aspects of the Coronavirus pandemic through student documentary photography
Authors: Jirásek Ivo , Stránský Bohuslav
Published: May 2022

Life for the population in the Czech Republic came to a standstill in spring 2020 due to measures enacted in relation to the Coronavirus epidemic: a travel ban and closed borders, the cancellation of physical lessons at all types of school, the closure of stores except those securing basic necessities, radical restrictions to free movement of people. This unprecedented situation became the inspiration for creative work by students at the Studio of Advertising Photography at Tomas Bata University in Zlin. Since joint work in the studio was not possible, the students were given their assignments as part of the Digital Photography classes in the form of a document reflecting the social situation during the Corona crisis. Selected visual narratives, or photo novellas, are a methodical component of arts-based research, meaning the use of art artefacts and imagination for a more complete knowledge of this mode of social reality. Verbal commentary complements the images’ topic by interpreting the main themes of the selected photographic images: Easter festivities without religious services, sewing facemasks and covering faces, newly discovered meanings of borders and emptiness, the social role of meals in family life. The Coronavirus crisis has revealed the hidden opportunities of a new way to see and discover again how to evaluate our everyday life, something which in the haste of each ordinary day can become subconscious routine.

General Introduction
Authors: Gobbi Mary
Published: May 2022

The papers in this Edition of the Journal comprise five ‘general papers’ and five in the COVID 19 section. Together, the papers clearly illustrate our theme of ‘Resilience and responsiveness’. The general papers mark states of transition, whether student, staff, or institution; the capacity and ability of stakeholders to be responsive to trends and more importantly their resilience to unfolding circumstances. Examples of these transitions include, academics learning new ways of education (outcome-based education, measuring aspects of the Bologna Process); institutions sustaining historical models of education, mission, and strategies; students experiencing and reacting to changes in the educational experience as pedagogies, processes, modes of delivery and philosophies change around them. In the COVID-19 section, resilience and responsiveness are evident driven by the need to face the challenges of the moment and times.

Protection of Children’s Rights and Interests in Transnational Surrogacy -- From the Perspective of Parent-Child Relationship
Authors: Liu Xiao
Published: May 2022

The development of artificial reproductive technology and the legal difference of surrogacy lead to a large number of transnational surrogacy children and many disputes about the legal parent status of transnational surrogacy children. The main reasons for the difficulty in identifying the parental relationship of the present transnational surrogacy children are the different identification of the surrogacy agreement and the parent-child relationship in different countries, the emergence of the "lame parental right" caused by the application of the principle of public order, and the reflect to recognize the transnational surrogacy parent-child relationship on the grounds of legal evasion.Based on the analysis of the reasons for the difficulty in identifying the parent-child relationship and the experience of determining the surrogate parent-child relationship in various countries, the exploration of the path to determine the parent-child relationship of the transnational surrogacy children mainly includes establishing the parent-child relationship according to the surrogacy agreement, establishing the adoption relationship to establish the parent-child relationship, and redefining the parent-child relationship according to the conflict norms of the country where the intended parents are located.At present, there is no basic law to regulate surrogacy in China. In practice, the legal parents of surrogacy children are established in the way of confirming the parentage of factual support. On the premise of balancing the best interests of children and social public order, we should protect the right of identity of transnational surrogacy children by perfecting laws and regulations, and maximize the function of technology to benefit mankind.

Published: May 2022

In recent years, environmental problems caused by global warming--- melting glaciers, rising sea levels, frequent wildfires and the death of large coral reefs, moved from the pages of the books to reality. To solve the problem, we develop several mathematical models, using both qualitative and quantitative methods, analyzing the importance of each influencing factor, finally build evaluation model of ecological environment and nature reserve.Firstly, in order to make a comparative analysis of the environmental conditions before and after the restoration of Saihanba, I collect the data of forest coverage rate, water conservation, PM2.5, oxygen release and carbon dioxide absorption of Saihanba in 60 years from 1962 to 2021, establishing Entropy Weight Method and Technique for Order Preference by Similarity to an Ideal Solution model (EWM-TOPSIS). Obtained that water conservation was the index with the largest weight, forest coverage rate is the index with the least weight, and the ecological environment in this area is the best in 2021 and the worst in 1962, indicating that saihanba restoration plays a significant role in improving the environment in this area.Secondly, I analyze the correlation between saihanba and Beijing's ecological environment, and qualitatively judge the degree of impact between the two. Then I take five ecological environment indexes of Saihanba as independent variables and four indexes of Beijing's anti-sandstorm ability as dependent variables of four Multiple Linear Regression models (MlR), which helps me make quantitative judgment, and finally get the conclusion that the improvement of the ecological environment of Saihanba will promote the anti-sandstorm ability of Beijing.After modelling, I also conduct sensitivity analysis to experiment the sensitivity of some parameters included in my models. In the end, I summarize strengths and weaknesses and a brief conclusion is also presented.

Fuzzy model based multivariable predictive control design for rapid and efficient speed-sensorless maximum power extraction of renewable wind generators
Authors: Babes B. , Hamouda N. , Kahla S. , Amar H. , Ghoneim S. S. M.
Published: May 2022

Introduction. A wind energy conversion system needs a maximum power point tracking algorithm. In the literature, several works have interested in the search for a maximum power point wind energy conversion system. Generally, their goals are to optimize the mechanical rotation or the generator torque and the direct current or the duty cycle switchers. The power output of a wind energy conversion system depends on the accuracy of the maximum power tracking controller, as wind speed changes constantly throughout the day. Maximum power point tracking systems that do not require mechanical sensors to measure the wind speed offer several advantages over systems using mechanical sensors. The novelty. The proposed work introduces an intelligent maximum power point tracking technique based on a fuzzy model and multivariable predictive controller to extract the maximum energy for a small-scale wind energy conversion system coupled to the electrical network. The suggested algorithm does not need the measurement of the wind velocity or the knowledge of turbine parameters. Purpose. Building an intelligent maximum power point tracking algorithm that does not use mechanical sensors to measure the wind speed and extracts the maximum possible power from the wind generator, and is simple and easy to implement. Methods. In this control approach, a fuzzy system is mainly utilized to generate the reference DC-current corresponding to the maximum power point based on the changes in the DC-power and the rectified DC-voltage. In contrast, the fuzzy model-based multivariable predictive regulator follows the resultant reference current with minimum steady-state error. The significant issues of the suggested maximum power point tracking method, such as the detailed design process and implementation of the two controllers, have been thoroughly investigated and presented. The considered maximum power point tracking approach has been applied to a wind system driving a 5 kW permanent magnet synchronous generator in variable speed mode through the simulation tests. Practical value. A practical implementation has been executed on a 5 kW test bench consisting of a dSPACEds1104 controller board, permanent magnet synchronous generator, and DC-motor drives to confirm the simulation results.

Background: Wound healing in diabetes mellitus is a complex multi-stage process that requires the proper function of multiple systems. The

mechanisms of impaired wound healing of diabetic wounds are still poorly understood. Therefore, various interventions are being used for wound

management without great success. Bee products have various properties that make them an important addition to the diabetic wound management.

Methods: This review summarized previous and recently published papers of the effects of two bee products, propolis and bee venom, on the wound

healing. The main results were obtained from preclinical experimentation.

Results: Diabetes mellitus compromises immune system, increases infections, impairs wound healing, and affects cells and factors involved in the

wound healing. There is an increasing interest in natural products in modern medicine as part of disease management. Bee products are natural

substances that others and we have explored some of their biological activities and applications in the treatment of various diseases. Some of these

products are bee venom and propolis. These products have analgesic, antioxidant, antimicrobial, and anti-inflammatory properties. In addition, both

propolis and bee venom contain considerable amounts of antioxidants that have a great role in accelerating wound healing.

Conclusion: There is sound rationality and scientific data for using propolis and bee venom in diabetic wound healing. We believe that topical

application of propolis in addition to bee venom might have a place in repairing damaged tissues and accelerating the healing of diabetic wounds.

Published: May 2022

Background: Veronia anthelmintica (Kaliziri) is a medicinally very important plant as being reported for remarkable therapeutic potential. The

present research evaluates its antischistosomal activity.

Methods and Materials: 54 buffaloes naturally infected with Schistosomiasis were used for anthelmintic trails. All animals for the study were

tagged so as to distinguish from others. The animals were checked up on routine basis by a veterinary doctor. Preparation of samples of herbal

drug and experiment was design according to available literature.

Results: During present studies, buffalos naturally infected with Schistosomiasis were treated with Veronia anthelmintica (Kaliziri), with dose

75 mg/kg, 150 mg/kg and 225 mg/kg body weight respectively, and their impact on various parameters like eggs reduction, milk production,

weight gain and feed intake was noted. Furthermore, their efficiency (%) was compared with standard drug “Praziquantel” (allopathic drug) at

“10mg/Kg” body weight dose level. The effectiveness (%) of “Praziquantel” was noted as hundred after first dose, while the effectiveness for the

herbal drug get to this level after injecting of second dose of “225mg/kg body weight”. Statistically significant (P

Background: Peganum harmala have many biological and pharmacological activities such as antifungal, antibacterial, analgesic and antiinflammatory.

The present study was carried out to evaluate the antischistosomal activities of Peganum harmala with special reference to bovine

schistosomiasis in naturally infected buffaloes.

Methods and Materials: A total of 54 naturally infected buffaloes with “Schistosomiasis” of ages around five years were used for anthelmintic

studies. All of the buffaloes were properly marked so as to make a distinction from one other. A doctor of veterinary was available for daily checkup.

Samples prepared according to the available methods in literature.

Results: In the present study, naturally infected buffaloes with Schistosoma bovis were treated with Peganum harmala (Harmal, seed), with dose 75

mg/kg, 150 mg/kg and 225 mg/kg body weight respectively, and their impact on various parameters like eggs reduction, milk production, weight gain

and feed intake was noted. Furthermore, their efficiency (%) was evaluated with “Praziquantel” (allopathic drug) at “10mg/Kg body weight” dose

level. After first dose of “Praziquantel” hundred percent effectiveness was noted, while the same result obtained for herbal drug after giving second

dose of “225mg/kg body weight”. To evaluate the effect of herbal medicines on protein portions, sera of treated and control buffaloes were also

investigated.

Conclusion: From present findings, it is concluded that the herb Peganum harmala can easily replace Praziquantal (PZQ) with almost same

Published: May 2022

Background: This study was designed to ascertain this claim and to investigate the possible mechanism of action in relation to their phytochemical

contents, using crude extracts of N. latifolia and M. esculenta leaves on topical wound in a rat model of Type 1 diabetes.

Methods and Materials: The leaves were air-dried under shade and subjected to cold extraction in 95% ethanol. Normoglycaemic male Wistar rats

were subjected to 2-month high-energy diet/ fat emulsion manipulation and injected with alloxan (150 mg/kg BW/day, i. p.). Fasting plasma glucose

was determined after 7 days and rats with values exceeding 200 mg/dl were selected. 16 diabetic rats (120 – 180 g) were randomly assigned to four

groups of four animals each. Wound was inflicted on the back of each rat by excision method. The crude extracts were topically applied over a period

of 21 days. The scar tissues were removed at 7 days interval for collagen quantification and wound margin reduction was also monitored using

tracing paper.

Results: The crude extracts showed efficient wound healing activity as revealed by increased collagen content (scar tissues versus fresh wound

tissues ab initio). Percentage wound closure also progressed significantly (p< 0.05) upon topical application of the extracts.

Conclusion: The crude extract of N. latifolia leaves has proven to be more potent than that of M. esculenta in wound healing in Type I diabetic rats.

It stimulated wound contraction and collagen formation, making it a promising natural product for further screening in search of new chemical

entities that can be useful in diabetic wound management.
