During the COVID-19, university teachers’ informatization instructional leadership (TIIL) was adopted in many countries. This attracted widespread attention. This research derived six factors from the unified theory of acceptance and use of technology (UTAUT) including performance expectancy (PE), effort expectancy (EE), social influence (SI), facilitating conditions (FC) and behavioral intention (BI), added two new internal elements related to the individual teacher which are computer self-efficacy (CSE) and blended teaching competence (BTC). Before using the Partial Least Squares Structural Equation Modeling (PLS-SEM) to explore the contributing factors to TIIL by assessing interrelation between constructs within extended UTAUT model in this study. This pilot study aimed to examine the reliability and validity of modified scales incorporating Use Expectancy (UE) Scale including (PE Scale and EE Scale) used to measure use expectancy, SI Scale to measure social influence, FC Scale to measure facilitating conditions, CSE Scale to measure computer self-efficacy, BTC Scale to measure blended teaching competence, BI Scale to measure behavioral intention to adopt TIIL, and the TIIL Scale to measure teachers’ informatization instructional leadership. A total of 60 teachers from the large multi-disciplinary private undergraduate universities in Xi’an city of Shaanxi province in China participated in this research. The data was collected in November-December 2022 during the middle stages of COVID-19 pandemic. The PLS-SEM approach was used to evaluate the reliability and validity of the adapted scales. The internal consistency reliability was determined by composite reliability (CR) and Cronbach’s alpha. Convergent validity was assessed by outer loading and average variance extracted (AVE). Assessment of discriminant validity was measured by Fornell-Larcker criterion, Cross-loadings and Heterotrait-Monotrait Ratio (HTMT). Results showed after deleting nine items with lower than .40, Cronbach’s alpha values were all higher than .70. CR values were at a satisfactory level. All item values fulfilled the criteria of AVE, Fornell-Larcker criterion, cross-loadings, and HTMT. Research results revealed all adapted scales were valid and reliable to be used in future research. This study explored the influencing factors of TIIL in Chinese context, enriched the theory of TIIL, and provided practical support for the future development of TIIL.

A critical perspective and analysis of two-step thermochemical fuel production cycles
Authors: Lidor Alon , Bulfin Brendan 
Published: May 2024

Two-step thermochemical fuel production cycles powered using concentrating solar systems offer a route to convert solar energy to chemical fuels. In this work, we offer a critical assessment of the state of the art, a detailed technical analysis of this technology in terms of theoretical limitations and potential performance, and potential paths forward in the development of these processes. The state of the art for demonstrated reactor systems is analyzed using key performance indicators including energy efficiency, feedstock conversion extent, power output, and volumetric power density. The technical analysis first looks into the theoretical limitations on the cycles’ process conditions and the role of the redox material. This is followed by a detailed thermodynamic analysis of the state-of-the-art CeO2-based cycle, based on fixed bed mixed flow reactors, which closely represent the reactor designs used in demonstrations. Finally, a scale-up analysis is performed for the CeO2-based cycle. The results from the theoretical analysis agree well with trends seen in experimental demonstrations of the concept. From the analysis, the low power density of the CeO2-based cycle is highlighted as a critical design limitation that will seriously restrict further scale-up of this technology. We share perspective on this and other issues, and offer some outlook for future development.

Published: May 2024

In Ukraine, there is a tendency to increase the production of soft, fresh cheeses due to their technological features. The advantages of producing this product include efficient use of raw materials; the ability to sell the product without ripening or with a short ripening period (no more than 14 days); and high quality indicators. In general, cheese is considered a complete food product that covers part of a person's daily needs for nutrients and biologically active substances. Due to martial law in the country, loyalty in the sale of products plays a unique role, but the temperature regime of storage affects the safety of cheese. Therefore, the study aimed to determine the sanitary quality of soft, fresh cheese and to justify the parameters of product storage at a temperature of 6 °C. The research was conducted at the Regional State Laboratory of the State Service of Ukraine for Food Safety and Consumer Protection in Poltava Oblast and at the Department of Livestock Products Processing Technology laboratory of Poltava State Agrarian University. The research objects were samples of soft, fresh cheese without fillers produced at the Milk Local Product Expert Center of the Faculty of Animal Production and Food Technology. The indicators stipulated by the regulatory document for soft cheeses 4395:2005 “Soft cheeses. General technical conditions”. It was established that the investigated cheese (sample No. 6) met the requirements of the current standard in terms of organoleptic (appearance, taste and smell, consistency, dough color, pattern, shape), physicochemical (mass fraction of fat, table salt, water) and physicochemical parameters. Specific physicochemical characteristics (mass fraction of moisture, table salt, and fat in dry matter) of the cheese, according to the tests, were within the limits specified by SSTC. The studied samples of fresh soft cheese regarding microbiological parameters (pathogenic microorganisms, particularly Salmonella, Listeria monocytogenes, and Staphylococcus aureus) complied with regulatory documents when they were stored at +6 °C for two days. At the same time, it has been proven that storage of fresh soft cheese without fillers at a temperature of +20 ± 0.5 °C leads to the growth and presence of coliform bacteria in the E. coli group. As early as 48 hours later, the products did not meet the regulated norms of the current national standards.

Authors: Yevstafieva V. , Petrunenko A. 
Published: May 2024

The effectiveness of the development of the poultry industry depends on the veterinary well-being of farms, in particular, in relation to invasive diseases. One of the most widespread ectoparasites among poultry farms is the gamasic mite Dermanyssus gallinae. As a result of tick parasitism, the egg and meat productivity of chickens decreases, often the death of young birds. Dermanyssus ticks are hematophagous and can be carriers of pathogens of infectious diseases of chickens, including zooanthroponosis. The research method was used to investigate the presence of specific pathogens carried by Dermanyssus gallinae. In laboratory conditions, inoculation was carried out from the homogenate of ticks isolated from chickens and objects of poultry premises on nutrient media (blood agar, yolk-salt agar, Saburo, Simmons, Endo, Ploskirev, bismuth-sulfite agar). As a result of bacteriological studies of Dermanyssus gallinae isolated from different substrates, microorganisms belonging to three species and four genera were isolated – Staphylococcus spp., Enterococcus faecalis, Klebsiella pneumoniae, Escherichia coli. Dermanyssus ticks isolated from chickens were carriers of only two genera and one species of microorganisms – Staphylococcus spp. (37.5 %) and Euterococcus facalis (31.3 %). Moreover, monoisolates (77.8 %) were most often isolated from ticks, the majority of which were Staphylococcus spp. (44.5 %), less – Enterococcus faecalis (33.3 %). Bacterial associations were rarely identified (22.2 %). Dermanyssus ticks, isolated from the objects of the poultry house environment, turned out to be carriers of a larger spectrum of microorganisms, where Staphylococcus spp. were more often isolated (100 %) and Escherichia coli (43.8 %), less often – Klebsiella pneumoniae (37.5 %) and Enterococcus faecalis (18.8 %). The isolates were dominated by associations of microorganisms (62.5 %). The monoisolate was represented only by Staphylococcus spp. (37.5 %). The data obtained by us regarding the isolated microorganisms further expand the vector role of D. gallinae, proving their danger for poultry enterprises producing food products. In general, dermanyssiosis can seriously affect the health of chickens both because of ectoparasites – hematophages, and because of the ability to transmit pathogens.

The commercial viability of mushrooms in Bangladesh faces a challenge due to the mushrooms' short shelf life, arising from their high respiration rates, elevated moisture content, and the absence of a protective cuticular structure. To solve this problem, different ways of enhancing the packaging conditions have been explored. Our research focuses on the use of the inert gas, nitrogen, to extend the shelf life of Pleurotus ostreatus (oyster mushrooms). Nitrogen, being an inert gas, is assumed to ensure the preservation of the quality of fresh mushrooms. In our study, freshly harvested mushrooms were carefully packaged in polypropylene (PP) bags both with and without nitrogen gas. Which were then stored both at room temperature and in the refrigerator. Throughout the storage period, the changes in seven quality parameters - total soluble sugar (TSS), browning index (BI), weight loss, pH, moisture content, odor, and texture were assessed at two-day intervals. The results revealed no significant changes in TSS or pH levels compared to the controls. Notably, mushrooms stored in PP bags having nitrogen and stored in the refrigerator exhibited improved quality over eight days, showing better results in BI, moisture content, and texture.
