The aim of this study was to develop a fast RP-HPLC method for simultaneous measurement of two antidiabetic formulations (vildagliptin + remogliflozin and teneligliptin + remogliflozin) under identical experimental conditions. Using the Box–Behnken approach and response surface design, the interaction and quadratic influence of three variable parameters, acetonitrile %, pH of the mobile phase, and flow rate, on resolution between the peaks were optimized. To forecast the resolution of peaks (2.7 and 6.5) for the three anti-diabetic medications, the design space with desirability function was used to find the optimal chromatographic conditions. Isocratic elution with 58:42 acetonitrile and phosphate buffer (20 mM KH2PO4, pH adjusted to 4.9 with orthophosphoric acid) over a Zorabx C18 HPLC column with a flow rate of 1.2 mL min−1 separated all three analytes in 2.5 min. In addition, the optimized HPLC process was validated using ICH recommendations. The devised HPLC method’s precision and accuracy were proven by the low percent relative standard deviation (0.60–1.65%), good percentage recovery (98.18–101.50%), and low percentage relative errors (0.20–1.82%). The method’s robustness was also proven by slightly varying the five separate parameters. Finally, the accuracy of the proposed HPLC approach was confirmed using a standard addition method for simultaneous determination of vildagliptin + remogliflozin and teneligliptin + remogliflozin from formulations. Furthermore, the findings demonstrated that experimental design can be successfully used to optimize chromatographic conditions with fewer runs. The devised HPLC method for simultaneous quantification of two binary combinations utilizing the same chromatographic conditions is fast, accurate, precise, and easy, and it might be utilized in laboratories for routine quality control investigations on both formulations.

Authors: Baranauskas Gedas , Raišienė Agota Giedrė
Published: January 2022

Recent results of the Digital Economy and Society Index (52, 45%) and the European Index of Digital Entrepreneurship Systems (EIDES) (48%) illustrate an improved level of the digital performance in European Union countries and a significant progress towards unlocking the productivity of digital value co-creation and collaborative networks. It is also agreed that the rapid digitalization of the economy and the digital entrepreneurship approach fosters a transition of traditional business models to networked and integrated digital platform business models. Despite the well-recognized benefits of the digital entrepreneurship and the digital business ecosystem, application of emerging technologies and modern business models also brings inevitable sustainable management challenges. The main negative outcomes are in the disruption or exposure of vulnerabilities within collaborative organizational and social networks, the additional socio-technical pressure for both network supervisors and incumbents, and the asymmetry of digital information and resources, etc. Therefore, the present research provides a critical review on the scientific literature, a reconceptualization within the multi-level side effects, and an overview of the influence of the digital entrepreneurship within the sustainability and digital business ecosystem domains. The present paper delineates the sustainable digital entrepreneurship term and the combined conceptual framework of the digital sustainable value cycle.
Tracking the Path of the Green Consumer: Surveying the Decision-Making Process from Self-Transcendent Values to Supportive CSR Intentions
Authors: Eng Nicholas , Buckley Christen , Peng Rachel X.
Published: January 2022

This paper examines the relationship between individual traits and values of consumers and their decision-making process pertaining to purchasing green products from companies with a strong commitment to corporate social responsibility (CSR). Guided by the theory of planned behavior (TPB), the main goal of this online survey (N = 463) is to understand the relationship between self-transcendent values, environmentalism, attitudes, norms, perceived behavioral control, intentions, and purchase frequency to better understand how consumers make green purchasing decisions. A structural equation model shows support for our predictions that self-transcendent values significantly and positively predict environmentalism, which in turn predicted the TPB variables. Interestingly, only attitudes towards purchasing green products were significantly predictive of purchasing products from companies with strong commitments to CSR, which subsequently predicted actual purchase frequency. We hope that our research will benefit scholars and practitioners by contributing to the work in CSR and environmental communication.

Published: January 2022

The snow leopard (Panthera uncia) lives in alpine ecosystems in Central Asia, where it could face intensive climate change and is thus a major conservation concern. We compiled a dataset of 406 GPS-located occurrences based on field surveys, literature, and the GBIF database. We used Random Forest to build different species distribution models with a maximum of 27 explanatory variables, including climatic, topographical, and human impact variables, to predict potential distribution for the snow leopard and make climate change projections. We estimated the potential range shifts of the snow leopard under two global climate models for different representative concentration pathways for 2050 and 2070. We found the distribution center of the snow leopard may move northwest by about 200 km and may move upward in elevation by about 100 m by 2070. Unlike previous studies on the range shifts of the snow leopard, we highlighted that upward rather than northward range shifts are the main pathways for the snow leopard in the changing climate, since the landform of their habitat allows an upward shift, whereas mountains and valleys would block northward movement. Conservation of the snow leopard should therefore prioritize protecting its current habitat over making movement corridors.

Published: January 2022

At the present stage one of the most important factors in the economic growth of Russian regions is the production processes modernization based on the best available technologies (hereinafter—BAT), ensuring the reduction of the negative impact on the environment in cost-effective ways. The most important conditions for the successful implementation of BAT at regional enterprises is the creation of general institutional conditions at the all-Russian level and the supply of enterprises with domestic technologies meeting the criteria of the best available technology. Over the past several years, large-scale work has been carried out in Russia to amend legislation, prepare BAT reference documents, and form the institutional conditions for their implementation. However, sustainable outcomes in specific regions will require the further development of regional innovation systems, consistent with the needs of local enterprises in BAT. The article proposes a general regional mechanism for managing the sustainable development of an innovation system based on BAT. For its successful implementation, a set of practical recommendations for the Rostov region has been formed. Within the framework of the innovation regional infrastructure it was proposed to create a new institute for the implementation of BAT—the Regional BAT competence center, priority areas for the development of potential and promising BAT in the region were identified, a general pattern of interaction of the Regional BAT competence center with other participants in the process was developed.

Published: January 2022

Climate change is the most serious threat that the modern world has ever faced. This has led to increasing attention from the government, industries, researchers, and practitioners on the theme of green practice. Due to the heightened awareness of climate change, the hospitality industry is under pressure to implement green practices and reduce the environmental impact of their operation. The research aims at understanding the indicators that define green practice in the hospitality industry and then developing a model that can be used to measure the green score. The research identifies twenty-six indicators of green practice in the hotel industry. These indicators were clustered into six different criteria. Based on the identified indicators and criteria, an integrated fuzzy AHP-TOPSIS method is proposed to calculate the green score. The fuzzy AHP method is used to calculate the weight of the criteria and indicators, while the fuzzy TOPSIS method is used to calculate the green score and rank hotels. The fuzzy AHP result shows that the criterion “Recycling and Reuse” has the highest weight among the identified criteria, while “Green Training and Incentives” has the lowest weight. The application of the proposed method is demonstrated by using a case study of hotels situated in the Sultanate of Oman. The result shows that the 4-star and 5-star hotels in the Sultanate have green scores between 0.56 and 0.641 out of 1.0 at a 95% confidence interval. The results further show that having a high star ranking hotel does not necessarily mean that the hotel is better in terms of green practice. The developed model helps the hotel industry to understand the indicator and criteria, as identified in this research work, they need to improve in order to improve their overall green management practice.

Authors: Li Ming , Yu Zhonggen
Published: January 2022

The COVID-19 pandemic has unexpectedly affected the educational process worldwide, forcing teachers and students to transfer to an online teaching and learning format. Compared with the traditional face-to-face teaching methods, teachers’ professional role, career satisfaction level, and digital literacy have been challenged in the COVID-19 health crisis. To conduct a systematic review, we use critical appraisal tools from the University of the West of England Framework We removed the irrelevant and lower-quality results to refine the results and scored each selected paper to get high-quality studies with STARLITE. The number of finally included studies is 21. We used the PICO mnemonic to structure the four components of a clinical question, i.e., the relevant patients or population groups, the intervention (exposure or diagnostic procedure) of interest, as well as against whom the intervention is being compared and considered appropriate (outcomes). We formulated five research questions regarding teachers’ professional role, satisfaction, digital literacy, higher educational practice, and sustainable education. The study found that teachers’ professional roles changed complicatedly. Moreover, they were assigned more tasks during the online teaching process, which also implicated a decline in teachers’ satisfaction. After the COVID-19 pandemic, it is necessary to conduct a blended teaching model in educational institutes. Teachers should have adequate digital literacy to meet the new needs of the currently innovative educational model in the future. In addition, the study reveals that teachers’ digital literacy level, career satisfaction, and professional role are significantly correlated. We measured to what degree the three factors affected the online teaching and learning process. Ultimately, the study may provide some suggestions for methodological and educational strategies.
Using Product Design Strategies to Implement Circular Economy: Differences between Students and Professional Designers
Authors: Spreafico Christian , Landi Daniele
Published: January 2022

Different studies in the scientific literature have shown how the transition towards a circular economy (CE) can benefit from product design, although maintaining a rather broad and qualitative perspective of analysis. This study investigates and compares which product design strategies (from routinely design, structural optimization, industrial design and systematic innovation) are most used by students and professional designers to implement different CE strategies (i.e., waste reduction, reuse, remanufacturing, recycling and biodegradability). Students’ data were collected from year projects and MSc degree theses based on real industrial case studies and carried out in two Italian engineering universities, while those of professional designers, were collected from selected scientific articles. Among the main outcomes emerged that the design strategies deriving from systematic innovation were preferred by students quite clearly. The design strategies referred to industrial design, e.g., user-centered design and timeless design were preferred by professional designers. The design strategies related to routine design, i.e., materials substitution, reducing resources and energy consumption, and structural optimization, were indistinctly used by both students and professional designers. The obtained results and their discussion can be useful during eco-design teaching to show the main gaps that students should fill in comparison with professional designers.

Published: January 2022

Water resource planning and management necessitates understanding soil moisture changes with depth in the root zone at the farm scale. For measuring soil moisture, remote sensing methods have been relatively successful. Soil moisture is estimated from image data, using in situ moisture and an empirical scattering model via regression fit analysis. However, in situ sensor data are prone to misinterpretations, requiring verification. Herein, we aimed at investigating the application of soil moisture from the water balance model towards verification of in situ soil moisture sensor data before in situ data was assessed for its relationship with remote sensing data. In situ soil moisture sensor data was obtained at 10 and 30 cm, and CROPWAT8.0 furnished root zone soil moisture data. The correlation between the in situ soil moisture at 10 and 30 cm was 0.78; the correlation between the soil moisture from CROPWAT8.0 and the in situ soil moisture were 0.64 and 0.62 at 10 and 30 cm, respectively. The R2 between Sentinel-1 backscatter coefficients and in situ moisture were 0.74 and 0.68 at each depth, respectively. Therefore, the water balance model could verify sensor results before assessing in situ soil moisture data for relationship with remote sensing data.
Existence and Uniqueness Theorem for Uncertain Wave Equation
Authors: Gao Rong
Published: January 2022

In the real world, the indeterminate phenomenon and determinate phenomenon are symmetric; however, the indeterminate phenomenon absolutely exists. Hence, the indeterminate dynamic phenomenon is studied in this paper by using uncertainty theory, where the indeterminate dynamic phenomenon is associated with the belief degree and called the uncertain dynamic phenomenon. Based on uncertainty theory, the uncertain wave equation derived by the Liu process is constructed to model the propagation of various types of wave with uncertain disturbance in nature, where the Liu process is Lipschitz-continuous and has stationary and independent increments. First important of all, only the equation has solution which can be used to clearly depict the wave propagation influenced by uncertain disturbance. Therefore, the aims of this paper is to propose and prove a theorem of existence and uniqueness with Lipschitz and linear growth conditions.

Published: January 2022

Shiga toxin-producing Escherichia coli (STEC) and enteropathogenic Escherichia coli (EPEC) are foodborne pathogens that cause hemolytic uremic syndrome and fatal infant diarrhea, respectively, but the characterization of these bacteria from imported food in China are unknown. A total of 1577 food samples from various countries during 2015–2021 were screened for STEC and EPEC, and the obtained isolates were tested for antimicrobial resistance and whole genome sequencing analysis was performed. The prevalence of STEC and EPEC was 1.01% (16/1577) and 0.51% (8/1577), respectively. Antimicrobial resistances to tetracycline (8%), chloramphenicol (8%), ampicillin (4%), ceftazidime (4%), cefotaxime (4%), and trimethoprim-sulfamethoxazole (4%) were observed. The antimicrobial resistance phenotypes corresponded with genotypes for most strains, and some resistance genes were related to mobile genetic elements. All 16 STEC isolates were eae negative, two solely contained stx1 (stx1a or stx1c), 12 merely carried stx2 (stx2a, stx2d, or stx2e), and two had both stx1 and stx2 (stx1c + stx2b, stx1a + stx2a + stx2c). Although they were eae negative, several STEC isolates carried other adherence factors, such as iha (5/16), sab (1/16), and lpfA (8/16), and belonged to serotypes (O130:H11, O8:H19, and O100:H30) or STs (ST297, ST360), which have caused human infections. All the eight EPEC isolates were atypical EPEC; six serotypes and seven STs were found, and clinically relevant EPEC serotypes O26:H11, O103:H2, and O145:H28 were identified. Two STEC/ETEC (enterotoxigenic E. coli) hybrids and one EPEC/ETEC hybrid were observed, since they harbored sta1 and/or stb. The results revealed that food can act as a reservoir of STEC/EPEC with pathogenic potential, and had the potential ability to transfer antibiotic resistance and virulence genes.
Study of Decoupled Anisotropic Solutions in f(R, T, RρηTρη) Theory
Authors: Naseer Tayyab , Sharif Muhammad
Published: January 2022

In this paper, we consider isotropic solution and extend it to two different exact well-behaved spherical anisotropic solutions through minimal geometric deformation method in f(R,T,RρηTρη) gravity. We only deform the radial metric component that separates the field equations into two sets corresponding to their original sources. The first set corresponds to perfect matter distribution while the other set exhibits the effects of additional source, i.e., anisotropy. The isotropic system is resolved by assuming the metric potentials proposed by Krori-Barua while the second set needs one constraint to be solved. The physical acceptability and consistency of the obtained solutions are analyzed through graphical analysis of effective matter components and energy bounds. We also examine mass, surface redshift and compactness of the resulting solutions. For particular values of the decoupling parameter, our both solutions turn out to be viable and stable. We conclude that this curvature-matter coupling gravity provides more stable solutions corresponding to a self-gravitating geometry.

Published: January 2022

Ralstonia solanacearum is a pathogen that causes bacterial wilt producing severe damage in staple solanaceous crops. Traditional control has low efficacy and/or environmental impact. Recently, the bases of a new biotechnological method by lytic bacteriophages vRsoP-WF2, vRsoP-WM2 and vRsoP-WR2 with specific activity against R. solanacearum were established. However, some aspects remain unknown, such as the survival and maintenance of the lytic activity after submission to a preservation method as the lyophilization. To this end, viability and stability of lyophilized vRsoP-WF2, vRsoP-WM2 and vRsoP-WR2 and their capacity for bacterial wilt biocontrol have been determined against one pathogenic Spanish reference strain of R. solanacearum in susceptible tomato plants in different conditions and making use of various cryoprotectants. The assays carried out have shown satisfactory results with respect to the viability and stability of the bacteriophages after the lyophilization process, maintaining high titers throughout the experimental period, and with respect to the capacity of the bacteriophages for the biological control of bacterial wilt, controlling this disease in more than 50% of the plants. The results offer good prospects for the use of lyophilization as a conservation method for the lytic bacteriophages of R. solanacearum in view of their commercialization as biocontrol agents.

Authors: Schwarzmann Danielle , Freitag Amy , Dorfman Dan , Records David , Walz Meredith
Published: January 2022

This article is designed to provide the methodologies used to estimate the impact to the commercial fishing industry as a result of spatial zone management changes within Florida Keys National Marine Sanctuary and its study area, Monroe County, FL. The analysis provided here provides a template for how to estimate economic impacts when refined human use spatial data are not available. Utilizing existing habitat maps and economic data, this method downscales traditional economic methods using a spatial approach to match the fine-scale management approach utilized by the National Marine Sanctuary System. This approach allows the authors to estimate the economic impacts to the commercial fishing sector. The authors find that the proposed spatial zone changes may result in an estimated loss of 42 jobs, with 28 being harvester jobs, to the state of Florida. Additionally, $4.1 million in output and approximately $1.1 million in income may be lost. These estimates do not take into account the likelihood of substitution to alternative fishing grounds or adjusting the target species.

Published: January 2022

Natural disasters (such as earthquakes, floods, heatwaves and landslides), isolation and war affect the water access of millions of people worldwide. Developments in the areas of membrane filtration, photolysis and photocatalysis are important for safe water production and water re-use applications. This work aimed to test alternative ways to ensure effective disinfection of wastewater effluents: light-emitting diodes that emit at different wavelengths, photocatalytic membranes, and the combination of the two solutions. The different treatment processes were tested at the laboratory scale to assess their performance in the removal and inactivation of water quality indicator bacteria and fungi present in wastewater effluents. The membranes were found to be effective to retain the microorganisms (rejection values higher than 96%), while three small ultraviolet C light-emitting diodes that emitted light at 255 and 265 nm showed an excellent performance for inactivation (higher than 2.5-log inactivation of total coliforms and Escherichia coli after 10 min of exposure in real wastewater effluents). When photocatalytic membranes are used, ultraviolet A light-emitting diodes ensured effective treatment of the retentate (higher than 65%). The combination of these two processes is extremely promising since it ensures not only the production of a high quality permeate that can be reused, but also the treatment of the retentate.

Considering the priority of water supply, agricultural water supply capacity downstream of the Yeongsan River Basin was evaluated in this study. The water balance was analyzed using the Please check all author names carefullyMODSIM-decision support system (MODSIM-DSS) to evaluate the agricultural water supply capacity. MODSIM-DSS can also be used to analyze the watershed demand status and agricultural water supply facilities. In this study, the watershed inflow and agricultural reservoir inflow (supply) data for each watershed were obtained using the SWAT outflow data. SWAT was calibrated and validated using 16-years (2005–2020) of daily streamflow data from one water level station and two weirs, by considering water withdrawal and return flows from agricultural, domestic, and industrial water use. The coefficient of determination (R2) was analyzed as 0.50 to 0.80 at three stations. Then, water balance analyses were performed for 41 years (1980–2020) by applying the SWAT outflow results to MODSIM-DSS. The results showed that agricultural water shortages of 517.8 × 106 m3, 520.0 × 106 m3, 579.8 × 106 m3, and 517.5 × 106 m3, occurred in 1992, 1994, 1995, and 2015, respectively. The efficiencies of agricultural water supply for these years were 58.2%, 58.0%, 53.2%, and 58.2%, respectively, which were lower than the 40-year average of 84.5%.

The process of carbon dioxide (CO2) reduction to value-added chemicals is being extensively studied worldwide. The main purpose is to decrease emissions to the environment that are associated with global warming, as well as the creation of renewable and sustainable energy sources. In the aforementioned process, the absorption of CO2 is of paramount importance as well as the reactor where the CO2 conversion takes place. In this context, the objective of this chapter is to present and analyze the results of the CO2 absorption in alkaline solutions in capillary reactors. A hydrodynamic study is included in order to establish the operational window of liquid and gas velocities in order to achieve the Taylor flow regime. All experiments were conducted in a capillary reactor (dc = 3 mm). The studied variables were temperature, NaOH concentration (0-0.75 M) and capillary length (300 and 100 mm). It was found that the volumetric mass transfer coefficient of the absorption of CO2 in water increases when the temperature decreases, while the CO2 absorption in NaOH solutions increases directly with temperature. By means of the Ha number, it was concluded that the mass transfer controlled the absorption process when using alkaline solutions.

Authors: Kravchenko E. N. , Shevchuk O. M.
Published: January 2022

Morphological features were revealed and the seed quality of samples of shrubby perilla ( Perilla frutescens (L.) Britton) was determined when introduced to the Southern coast of the Crimea in a subtropical climate of the Mediterranean type. It is shown that samples of various geographical origin under the conditions of introduction undergo all cycles of development, are characterized by high variability of morphological parameters and aroma; form full-fledged seeds with high laboratory (79-92%) and field (75-90%) germination. The application of the X-ray method showed that the seeds have a high degree of completion (57-95%), correlated with germination. The mass of 1000 seeds of the studied samples varies from 1.25 to 1.86 g. The use of light microscopy methods allowed us to study the size, shape, color and surface pattern of the seeds, and to establish that the length of the seeds of shrubby perilla of its own reproduction varies within 1.44-2.23 mm, width - 1.33-1.89 mm.

This study aimed to study, collect, analyze, and record the oral narratives of the Manobo tribe in Barangay Magulibas, Jose Abad Santos, Davao Occidental. Also, this study aims to determine each value and educational implication found in the oral narratives collected. This study uses qualitative-narrative analysis composed of ten research participants, nine Manobo tribal elders, and one tribal literacy teacher. The researcher collected thirty oral narratives of Manobo, consisting of eight legends and twenty-two folktales, which were identified using Eugenio’s Classification of Oral Narratives. The researcher uses the Triangular Translator to explain the guide questionnaire, which is translated from the Manobo language to Visayan language. The values found from the collected oral narratives were based on Classification of Values by Andres. Findings reveal that the values and educational implications found in the oral narratives of Manobo mirror the culture, tradition, and way of living of the tribe. These collected oral narratives of the Manobo will be used to learn and guide future researchers.
