Redesigning Teacher Education in the Wake of Covid-19 and Future Emergencies: A Case of Zimbabwe
Authors: Chimbunde Pfuurai
Published: September 2021

Globally, the need to mitigate the spread of Covid-19 had rendered the traditional face-to-face educational delivery systems of Higher Education (HE) irrelevant. In light of that, institutions of HE had abruptly introduced online teaching platforms as an alternative, though without auditing the lecturers’ capacities and skills. Informed by the Appreciative Inquiry Model (AIM), this interpretive case study used virtual meetings and WhatsApp discussions to explore the professional limitations of Zimbabwe university lecturers on using the online platforms and their reactions to Teachers Education Programmes in the wake of Covid-19 and future emergencies. 12 lecturers drawn from three purposively selected Zimbabwean universities participated in the case study. Data were generated from questions developed in a way that encouraged the appearance of the Appreciative Inquiry Model stages. Findings suggest that some lecturers in Zimbabwe and possibly in other developing countries are inadequately trained to use online platforms. Institutions of Higher Education are therefore suggested to regularly audit their lecturers’ skills and professionally capacitate them for re-tooling and aligning in order for the skills to match the dictates of future emergencies.

Suspension of Glycosaminoglycans in Oleogel Environment and Application Perspective in GcMAF Immunotherapy
Authors: Zima J.
Published: September 2021

The aim of this work was to find out the optimal concentration of gelling agents or their optimal combination in the olive oil environment to stabilise the suspension of chondroitin sulphate. Purified olive oil was structured with rice bran wax or a combination of gelators – soy lecithin and sorbitan tristearate. Rice bran wax creates a viscous fluid without a gel structure. The combination of soy lecithin and sorbitan tristearate forms a gel structure from 5 wt.% of the concentration. The optimal ratio of soy lecithin and sorbitan tristearate was found to be 3:2 wt.%. Oleogel was immobile at temperatures below 8°C; on increasing the temperature, it changed to a viscous liquid. The oleogel environment opens new possibilities for creating oral route immunotherapy approaches such as glycoprotein-derived macrophage activating factor-derived immunotherapy.
Possibilities of microemulsion application in rectal administration of indomethacin
Authors: Špaglová M. , Čuchorová M. , Čierna M. , Mikušová V. , Bauerová K. , Poništ S.
Published: September 2021

Rectal administration is a suitable route of administration for drugs that are either very irritating to the intestine (e.g., indomethacin) or are more effective when the first-pass effect in the liver is circumvented. Microemulsions are a tool for the improvement of penetration of sparingly soluble drugs. They are mainly used in topical and transdermal drug delivery. However, they find application also in other routes of administration, mainly due to their ability to solubilize sparingly soluble drugs. The selection of a suppository base depends on the physical properties of the drug. The study focused on evaluating the effect of the microemulsion as the solubilizer of sparingly soluble indomethacin in hydrophilic and lipophilic suppository bases compared with Polysorbate 80 as the excipient contained in the microemulsion. The reference suppositories were prepared by the traditional moulding technique from Adeps solidus or Macrogol suppository base without the previous drug solubilization. The microemulsion-based suppositories were prepared after the initial solubilization of the drug in the microemulsion or Polysorbate 80, followed by the addition of suppository base to maintain the same drug/solubilizer ratio. The suppositories were tested for softening time, hardness, and uniformity of mass. The dissolution test was performed using the dialysis tubing method in the basket apparatus. The amount of indomethacin released into the dissolution medium was determined spectrophotometrically at 320 nm. The results indicate that solubilization of indomethacin in the microemulsion had a positive effect on in vitro drug release but not as significant as in the case of Polysorbate 80 used alone. The enhancement ratio for Polysorbate 80 in Adeps suppositories was 2.9, for the microemulsion in Adeps suppositories was 1.1, and for Polysorbate 80 in Macrogol suppositories was 7.4 after 3 hours. The test of uniformity of mass had shown that all suppositories (reference, solubilizer-containing) are within the permitted limits. The softening time was reduced by adding the solubilizer to each type of suppository base.

Published: September 2021

In construction, textiles can be used either for reinforcing the structure or for finishing design. When we talk about function, the interior is no less important than the exterior and architecture of the building. Thus using textiles to reinforce the structure of buildings, textiles often perform a desired function of reinforcing the “finish.” Building textile materials include fibers that are mixed with concrete, fiberglass reinforcement meshes, insulators, etc. Textile architecture covers permanent tensile structures based on polyester or glass fiber fabrics, with polyvinyl chloride (PVC) or polytetrafluoroethylene (PTFE) coating and awnings generally supported by polyester or polyolefin fabrics, with or without coating, especially for gardening. All above topics are covered within this perspective with the experts from the group of smart textiles for building and living within COST Action CA17107 European Network to Connect Research and Innovation Efforts on Advanced Smart Textiles (CONTEXT) [1].

Published: September 2021

In this paper, energy band gaps and electrical conductivity based on aluminum selenide (Al2Se3) thin films are synthesized electrochemically using cathodic deposition technique, with graphite and carbon as cathode and anode, respectively. Synthesis is done at 353 K from an aqueous solution of analytical grade selenium dioxide (SeO2), and aluminum chloride (AlCl2·7H2O). Junctions-based Al2Se3 thin films from a controlled medium of pH 2.0 are deposited on fluorine-doped tin oxide (FTO) substrate using potential voltages varying from 1,000 mV to 1,400 mV and 3 minutes −15 minutes respectively. The films were characterized for optical properties and electrical conductivity using UV-vis and photoelectrochemical cells (PEC) spectroscopy. The PEC reveals a transition in the conduction of the films from p-type to n-type as the potential voltage varies. The energy band gap reduces from 3.2 eV to 2.9 eV with an increase in voltage and 3.3 eV to 2.7 eV with increase in time. These variations indicate successful fabrication of junction-based Al2Se3 thin films with noticeable transition in the conductivity type and energy band gap of the materials. Consequently, the fabricated Al2Se3 can find useful applications in optoelectronic devices.

Published: September 2021

This work is one of the first studies on the growth ofPoecilia latipinnaoutside its natural habitat. The objective of our study was to investigate the growth parameters of the population ofP. latipinna, which is an alien species in Oman (Wadi Al-Bahayes). The population structure ofP. latipinnain Wadi Al-Bahayes (Oman; 23°40′47″N; 58°11′36″E) was studied in June and August 2020, using 124 fish. In the course of this study, the number of individuals of each sex, age, weight and size composition were determined. In addition, the total length–weight relationship (LRW) was calculated, as well as the von Bertalanffy growth equation. The mean growth performance (phi prime) and the condition factor were calculated. Males accounted for 37.10% and females for 62.90% of the population. The length–weight relationship and the von Bertalanffy growth equation were W = 0.0214 × L2.7889R2= 0.9212, Lt = 11.46 (1 − e−0.127 (t + 2.71)) for males and Lt = 14.51 (1 − e−0.072 (t + 3.98)) for females. The mean growth performance and the condition factor were calculated as 1.22 for males and 1.18 for females and 1.54 for all specimens.

The study shows that the population of the species is characterized by a wide age range. Consequently, monitoring of this alien species is highly recommended.
First record of straight-needle pteropodCreseis aciculaRang, 1828 bloom in the Çanakkale Strait (NE Aegean Sea, Turkey)
Authors: Tunçer Sezginer , Öğretmen Nazik , Çakır Fikret , Öztekin Alkan , Oral Ayhan , Suner Salih Can
Published: September 2021

Pteropods are marine pelagic calcifier mollusks sensitive to chemical changes in seawater due to their highly soluble aragonite shells. Increased acidity (reduced pH) of seawater causes difficulties in precipitating their shells and/or results in their dissolution, which is related to increased atmospheric CO2concentrations and warming of seawater. They are therefore indicators of environmental changes. In this paper, we present the first record of the straight-needle pteropodCreseis aciculaRang, 1828 bloom in the surface waters of the Ҫanakkale Strait, Turkey (NE Aegean Sea), encountered in July 2020, when the highest sea surface temperatures and pH levels since 2007 were recorded. In coastal zones, such as the Ҫanakkale Strait, anthropogenic activity contributes significantly to environmental changes. Consequently, the increase in pH at elevated temperatures indicates an auxiliary factor (i.e. anthropogenic activity) that triggered theC. aciculabloom, rather than global atmospheric CO2levels.

Resilience factors in the Russian economy: The comparative analysis for 2000–2020
Authors: AKBERDINA Viktoriya V.
Published: September 2021

Subject. The study investigates the impact of shocks on the economic dynamics during recurring crises. Nevertheless, the impact of exogenous shocks may turn to be minor for GDP of some countries, while they cause unfavorable consequences for the economic development of others.
Objectives. I herein identify factors of resilience in the Russian economy, referring to three different crises that took place in 2000–2020, by conducting a theoretical overview of the concept Economic Resilience and resilience factors of economic systems against different shocks.
Methods. The decomposition of macroeconomic indicators is the principal method of research. The resilience of the Russian economy and other advanced economies was assessed by macroeconomic indicators related to trends in GDP and the unemployment level. I point out two groups of factors – the innate and acquired (adaptability).
Results. During the global financial crisis in 2008, the Russian economy demonstrated its innate factors, such as the availability of considerable reserves and capital mobility between the financial and industrial sectors, as well as adaptive factors as part of the national anti-crisis policy. During the period of sanctions, the resilience of the Russian economy stemmed from the enormous potential of the industrial sector and R&D, considerable reserves for production development, which underlay the import substitution policy. Finally, in the outbreak of the 2020 crisis, Russia managed to handle the crisis much better than the leading countries of the world, since there is a prevalence of State-owned large business and the domestic localization of value added chains.
Conclusions and Relevance. The study substantiated the objectivity of resilience factors of the Russian economy during multiple crises, i.e. a combination of financial, commercial, political and pandemic crises.

Assessing the extent of digitalization across types of economic activities is the key issue for setting up the socio-economic development strategy of the region and evaluating its efficiency.
Objectives. The study is aimed to formulate and test methodological approaches to assessing the digitalization in types of economic activities and the potential of digital technologies for the real economy.
Methods. The study relies upon the dialectical method, systems approach, questionnaires, expert approach, interpretation of empirical facts through tables, etc.
Results. We devised a methodological approaches to assessing the extent of digitalization in types of economic activities across regions. The approach combines the quantification and evaluation of the process and helps determine the extent of local digital transformation at the regional level. We devised and tested the methodological approach to rating digital technologies, which have the high potential for raising the competitiveness and resilience to competition of the industrial sector in the Russian regions. As opposed to the existing approaches, the approach accounts for the current scale of digital technologies in the national economy, the potential for growth in the demand and supply in the domestic and foreign markets, and the potential for import substitution with respect to foreign technologies and products.
Conclusions and Relevance. What makes the proposed methodological approaches more preferable is that they help assess not only the extent of digitalization in types of economic activities and the predominance of certain types in industrial enterprises, but also determine their potential for import substitution in terms of digital security.

Authors: Rao Pooja , Winchester Yasaswini , Varatharajan Rameshkumar , Venugopal Gopikrishnan , Manikkam Radhakrishnan
Published: September 2021

The present study attempted to explore actinobacteria from different insect nest samples for antimicrobial activity. Totally, 43 actinobacterial colonies were recovered from ant nest, termite nest, wasp nest and blanket worm nest samples by adopting standard spread plate method. Screening of antimicrobial properties of actinobacterial strains was determined by agar plug method. Two actinobacterial strains AN1 and AN5 showed promising activity (14-18 mm inhibition) against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, carbapenem resistant Klebsiella pneumoniae and Mycobacterium smegmatis. Both the strains produced antimicrobial compound earlier on ISP2 agar when compared to ISP2 broth. Crude extracts from the strains AN1 and AN5 were produced by adopting agar surface fermentation and extracted using ethyl acetate. Based on the studied phenotypic characteristics, actinobacterial strains AN1 and AN5 isolated from ant nest were identified as Streptomyces sp. In addition to antimicrobial activity, extracts also showed anti-HIV activity. This study concluded that insect nest is a promising source for bioactive actinobacteria. Two potential Streptomyces sp. AN1 and AN5 isolated from ant nest will be promising sources for antimicrobial metabolites against drug resistant bacteria, retrovirus and mycobacterial pathogens.
Immunopathogenesis and Immunotherapeutic Strategies in Rheumatoid Arthritis
Authors: Qamar Tooba , Mukherjee Sayali
Published: September 2021

Rheumatoid Arthritis (RA) is a systemic autoimmune disease which results from failure of immune tolerance. Autoantibodies like Rheumatoid factor, Anti-Carbamylated Antibodies, Anti-Acetylated and Anti- Citrullinated Protein Antibodies keep on circulating in blood which target self-tissues. The major symptoms of RA are polyarticular inflammation of the synovial membrane, wrists and feet along with the joint tenderness and formation of nodules in the joints. There are many MHC alleles as well as non-MHC immunoregulatory genes which confer the genetic risk in Rheumatoid Arthritis. Immunotherapeutic strategies involved are dendritic cell targeted therapeutics, cell-based therapy and autoantibody-mediated refractoriness. The increase in the mortality rate of RA is recognized widely but different aspects of immunopathogenesis are not explained fully. The aim of the review article is to discuss all the factors that can contribute towards the immunopathogenesis of this disease and to screen out the most prominent immunotherapeutic strategies.

Published: September 2021

Seaweeds play crucial roles in maintaining marine ecosystems and can be utilized as a raw material for cosmetic and therapeutic applications. A red seaweed Portieria hornemannii exhibits pleasant smell and habituating along with the coral reefs was collected from the Gulf of Mannar, Tamil Nadu. Association between the above red seaweed and coral reefs is not studied in detail. We have extracted essential oil from P. hornemannii and characterized it using GC-MS and SEM techniques. The extracted essential oil was studied for antimicrobial and anti-dandruff properties. Subsequently, an antibacterial film was created with carrageenan biopolymer blended with the extracted seaweed essential oil. Bio-physical, mechanical and anti-microbial properties of the essential oil-coated Carrageenan biopolymer were explored. Scanning Electron Microscopic investigation of after-effects has confirmed the consolidation of essential oil with carrageenan biopolymer. Further, increases in the concentration of essential oil have also improved the elasticity of the film. All these examinations confirmed the elasticity and antimicrobial nature of the biodegradable composite film which can be used in food packaging and therapeutic industries.

Lowered risk of dental carries and bone demineralization further support its involvement in a healthy lifestyle. In addition, its role in the synthesis of various commercial products like glycol, ethanol, and resins etc. increases its market value and makes it one of the most valuable bio-products. Microbial fermentation is a cost-effective and eco-friendly method for xylitol production from agricultural residues as available xylose is reduced to xylitol by Xylose reductase (XR) using an equivalent amount of NADPH as a mediator for electron transfer. Previous literature emphasized the use of fungi and yeast for xylitol production rather than bacteria. In contrast to available reports, the potential of the bacterial isolate was evaluated for xylitol production. The effect of process parameters was observed on xylitol yield in terms of XR activity. Out of sixty-eight bacterial isolates obtained, XYLBV-05 was selected for XR production after screening and was identified as Citrobacter sp. based on morphological, microscopic, and biochemical characteristics. Parametric analysis increased the XR production by 4.12 folds (36.61 U/ml). Preliminary results also proved its efficiency in conversion of biomass hydrolysate to xylitol at lab scale but further efforts are needed for xylitol production using agro-industrial lignocellulosic biomass at a large scale which will not only aid in the generation of revenue as a result of value-added products but will also help in environment conservation.
Działalność badawczo-rozwojowa w branży energetycznej w krajach Europy Środkowej
Authors: Stec Sławomir
Published: September 2021

Artykuł zawiera charakterystykę działań związanych z innowacyjnością w branży energetycznej w krajach Europy Środkowej, a dokładnie w Czechach, Polsce, Słowacji i na Węgrzech w latach 2009–2018. Podstawowym problemem badawczym było przedstawienie dynamiki zmian w obszarze działalności badawczo-rozwojowej ze szczególnym uwzględnieniem wydatków rządowych we wspominanej branży na badania i rozwój. Dodatkowo poddano analizie stan personelu B+R oraz liczbę uzyskanych praw własności intelektualnej w działalności z zakresu zaopatrzenia w energię elektryczną, gaz, parę wodną i klimatyzację. W artykule dokonano również analizy barier, które przyczyniają się do zmniejszenia dynamiki rozwoju innowacyjności i spadku zainteresowania prowadzeniem badań i rozwojem w omawianej branży energetycznej. Przedstawiono zachęty podatkowe w poszczególnych państwach związane z prowadzeniem działalności innowacyjnej. Z badań wynika, że wskaźniki innowacyjności sektora zaopatrzenia w energię eklektyczną są na niskim poziomie, a przedstawiona dynamika ostatniej dekady wskazuje na niewielkie zmiany w tym zakresie. Wymienione bariery we wdrażaniu innowacji to głównie problemy z finansowaniem i złe doświadczenia z wcześniejszego stosowania innowacji. Wnioskuje się, że przed rządami omawianych krajów istnieje wiele zadań, aby zintensyfikować działania w celu jak najszybszego rozwoju działalności B+R w sektorze zaopatrzenia w energię elektryczną, a w szczególności uruchomienie zwiększonych strumieni finansowych, podtrzymanie polityki stosowania ulg podatkowych na działalność innowacyjną, a także promocję innowacji.
Wpływ procesu europeizacji na administrację publiczną we współczesnej Polsce. Wybrane przykłady i wnioski
Authors: Wardziński Bernard
Published: September 2021

Integracja Polski z Unią Europejską wymusiła na rodzimej administracji liczne modyfikacje, a co za tym idzie – odpowiednie procesy dostosowawcze. W organach administracji krajowej nastąpiło dostosowanie struktury organizacyjnej i systemowej do potrzeb i warunków administracji unijnej, bowiem rodzima administracja stała się jej częścią. Zachodzące w administracji krajowej procesy można nazwać europeizacją i stwierdzić, iż dzięki nim nastąpiło funkcjonalne połączenie obu administracji. Fuzja ta możliwa była dzięki przeobrażeniom administracji następującym w Polsce już w okresie przedakcesyjnym. Powstanie nowych urzędów, zaangażowanie urzędników, reformy administracyjne miały przynieść rodzimej administracji określone skutki, czyli poprawę funkcjonowania władzy publicznej. Czy tak się stało? Wydaje się, że nie, ponieważ interaktywny proces europeizacji krajowej administracji nie jest jeszcze w pełni zakończony.

Rola języka angielskiego w funkcjonowaniu sektora TSL
Authors: Laniecka Patrycja , Puchała Maciej
Published: September 2021

Artykuł poświęcony jest problematyce stosowania zapożyczeń z innych języków w języku polskim, w szczególności dotyczy to branży TSL. Na początku autorzy przybliżają czytelnikowi znaczenie skrótu TSL i charakter relacji pomiędzy poszczególnymi określeniami. Następnie poruszona jest kwestia języka w różnych branżach, jego znaczenie komunikacyjne i społeczne. Na tym tle pojawia się kwestia zapożyczeń językowych. Po takim wprowadzeniu omówiono rolę języka w sektorze TSL i zapożyczeń językowych specyficznych w tej branży. Postawiono pytanie, czy zapożyczenia są konieczne i czy nie przeszkadzają w rozwoju branży. Narzędziem badawczym był wywiad z językoznawcą. Wywiad ten nie potwierdził tezy, że zapożyczenia przeszkadzają w rozwoju branży. Ekspert uznał, że następujące względy decydują o stosowaniu zapożyczeń: wygoda, potrzeba, pozorny prestiż, łatwość w komunikowaniu. Na zakończenie autorzy poruszają kwestię nauczania języków obcych w poszczególnych branżach, zwracając uwagę na niedobory odpowiednich specjalistów i na to, że znajomość języka obcego zwiększa szanse zatrudnienia młodych ludzi w atrakcyjnych zawodach.

Significance of Traditional Materials and Their Substitution with Newly Available Materials
Authors: Zamolyi Ferenc
Published: September 2021

This article focuses on the region of Central Timor, settled by the Atoni Meto people, who live in round houses built on the ground. There seem to have developed local peculiarities in vernacular architecture, which require the use of wooden materials of different size, shape and state of processing. Changes in local vernacular architecture were also induced by the recent availability of modern materials such as bricks, concrete and corrugated iron. The aim of this article is to explore how such building materials are used and whether they are/ can be integrated into local vernacular building traditions. Fieldwork conatining architectural survey was conducted in Timor in May 2004 in Maubesi, and in June 2011 near Soe and  Nikiniki (villages None, Supul and Boti)  and Kefamenanu (among others the villages of Fafenesu, Maslete and Tamkessi). Some of the materials seem to have a strong effect on the layout or design of the buildings, whereas in other cases, such effects are far more subtle. In some cases, the new materials are used to imitate the more traditional ones, with astonishing results, and often incorporating structural details from the older technology and traditional materials which are copied. New materials already influence the building due to their different, new properties, and designs are devised to adapt to these changes, which in the end result in an altered building. In other cases, there is no compatibility at all, and old forms and designs are abandoned in favour of a new concept supported by new materials
