Authors: Aziz Al Thabiani 
Published: July 2023

Abstract
Mosquito vectors in the present universe cause a major problem due to the transmission of pathogens with high morbidity. The present research aimed to explore the larvicidal and adulticidal toxicity of the Cladostepus spongiosus extract and its fabricated AgNPs on key mosquito vectors. The synthesized AgNPs were confirmed by UV-Vis spectroscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, Fourier transform infrared spectrophotometry, and X-ray diffraction analysis. In the mosquitocidal assay, the C. spongiosus extract has shown good larvicidal mortality against Aedes aegypti (88.9%), Anopheles stephensi (84.1%), and Culex. quinquefasciatus (81.6%). Further, adulticidal mortality percentages were 78.8%, 75.4%, and 67.6% against An. stephensi, Ae. Aegypti, and Cx. quinquefasciatus at 1,000 ppm. AgNPs revealed larvicidal mortality percentages of 94.8% against An. stephensi, 92.8% against Ae. Aegypti, and 90.6% against Cx. quinquefasciatus; the adulticidal potential was also revealed to be higher against An. stephensi (89.4%) followed by Ae. aegypti (86.8%) and Cx. quinquefasciatus (83.2%). Comparing the results achieved from the C. spongiosus extract and its derived AgNPs, promising activity was attained against key mosquito vectors at a minimal dose of 70 ppm of AgNPs. Thus, C. spongiosus-mediated AgNPs can be an alternative tool in controlling key mosquito vectors.

Abstract
The CeO2 and CeCoO composite oxide catalysts with bimodal mesopore structures were prepared by hard-template method and used for ethanol complete oxidation in air. The physicochemicalphysicochemical properties of the prepared catalysts were characterized by XRD, BET, TEM, XPS, H2-TPR, and O2-TPD. The Co species can be dissolved into CeO2 lattice to form Ce–O–Co solid solution, which promotes reactive oxygen species to be formed on the prepared CeCoO oxide catalysts surface. The bimodal mesopore structures can be obtained by the used hard-template method, and the pore structures of the prepared CeCoO oxide catalysts can be affected by the introduction of Co species. The synergistic effects from bimodal mesopore structures and reactive oxygen species can effectively boost ethanol complete oxidation to final product CO2. The CeCo2 catalyst with Ce/Co mole ratio of 2.0 exhibites superior ethanol complete oxidation activity and service stability, the ethanol oxidation conversion and final oxidation product CO2 selectivity reached 99.8 % and 99.2 % at 200 °C, respectively. This work indicates that the bimodal mesoporous CeCoO solid solution composite oxide catalyst is a promising candidate for OVOCs oxidation elimination from air.

Abstract
Natural fiber composite materials are able to compete with common synthetic materials in situations where the strength-to-weight ratio is important. In this study, we aim to analyze the mechanical, tribological, and surface morphology of composites fabricated from randomly oriented snake grass natural fiber with java plum seed filler. Different weight ratios of fiber to seed filler are chosen: 30:0, 28:2, 26:4, 24:6, 22:8, and 20:10. A 70 % epoxy resin was kept constant in all compositions. The fabricated hybrid composite samples were subjected to tensile, flexural, shear, Shore D hardness, water absorption, and wear tests as per ASTM standards, and the results were compared with those of snake grass mono fiber composites. The 20:10 composite has the maximum tensile strength, impact resistance, flexural strength, hardness, water absorption, and wear resistance compared to other composites. The fiber/matrix adhesion was explored using a scanning electron microscope (SEM). The 20:10 composite shows predominant mechanical and tribological characteristics, making it easier to utilize in structural and automotive applications.

Published: July 2023

Abstract
The aim of this study was to investigate an effective approach for improving the dissolving pulp properties for making specialty fiber. The caustic and enzymatic treatment of the properties of dissolving pulp was conducted by analyzing the macromolecular structure and chemical composition. The results showed that the enzymatic treatment was more effective on influencing the macromolecular properties, while the caustic treatment had more influence on structural changing, mainly cellulose crystal structure and crystallinity. Meanwhile, to maintain a higher purity and higher brightness, caustic treatment would be beneficial in comparison with enzymatic treatment. The performance of caustic treated sample was evaluated in regarding to chemical composition and acetylation reaction performance, using commercial pulp as reference. The competitive feature of treated sample suggested its potential in future application.
Identification of tuliposides K–M in tulip bulbs via an enzyme reaction-based screening method using a tuliposide-converting enzyme
Authors: Nomura Taiji , Omode Ayami , Kato Yasuo 
Published: July 2023

Abstract
Tuliposides (Pos) are major defense-related secondary metabolites in tulip, having 4-hydroxy-2-methylenebutanoyl and/or (3S)-3,4-dihydroxy-2-methylenebutanoyl groups at the C-1 and/or C-6 positions of d-glucose. The acyl group at the C-6 position is converted to antimicrobial lactones (tulipalins) by an endogenous Pos-converting enzyme. Based on this enzyme activity, we examined tulip bulb extracts and detected HPLC peaks that disappeared following the reaction by the Pos-converting enzyme. Spectroscopic analyses of the three purified compounds revealed that one of them was a glucose ester-type Pos, while the other two were identified as a glucoside ester-type Pos. These compounds were designated as PosK, L, and M. They were specific to bulbs, with the highest content in the outermost layer, but they were markedly less abundant than PosG, the minor bulb Pos we identified earlier. The study results suggest that tulip bulbs contain at least four minor Pos in addition to the major 6-PosA. Although PosK–M were present in almost all of the tested tulip cultivars, they were detected in only a few wild species, indicative of their potential utility as chemotaxonomic markers in tulip. Identification of PosK–M as 6-PosA derivatives unveils the biosynthetic diversity of Pos, the well-known group of secondary metabolites in tulip.

Published: July 2023

Abstract
Lignin is a natural copolymer found in plants that is a major waste from bioenergy and paper industries. In this study, comprehensive laboratory testing programs were carried out to evaluate the strength improvements and water resistance of soil after being stabilized by lignin and polymerized lignin. The chemical polymerization of pre-treated lignin involves a process of linking short lignin molecules to form longer ones and consuming hydrophilic functional groups to improve its stability under wet conditions. Various testing combinations were considered, including four lignin or polymerized lignin contents (0, 6, 8, and 10 %) and four lime contents (0, 2, 4, and 6 %). The results show that lignin-stabilized soil will take at least 14 days to reach maximum strength, whereas the minimum curing period is 21 days for soil stabilized with polymerized lignin. The optimum dosage is 8 % when lignin or polymerized lignin is used for soil stabilization. Polymerized lignin can provide approximately 10 to 20 % more strength improvement than lignin; however, lime seems work better with lignin than polymerized lignin when added as a strength booster. The water soaking tests showed that polymerized lignin has better moisture resistance than lignin, and additional lime can further improve the performance of stabilized soil with respect to water susceptibility. However, the strength of specimens cannot fully recover, decreasing slightly after each dry–wet cycle for both specimens treated by lignin and polymerized lignin. The total decrease is about 5∼10 % after two cycles. The temperature and pH value control and oxygen supply approach used in this study will be an important reference for future studies.

Published: July 2023

Cannabinoid-targeted pain therapies are increasing with the expansion of cannabis legalization, however, their efficacy may be limited by pain-induced adaptations in the cannabinoid system. Cannabinoid receptor subtype 1 (CB1R) inhibition of spontaneous, GABAergic miniature IPSCs (mIPSCs) and evoked IPSCs (eIPSCs) in the ventrolateral periaqueductal gray (vlPAG) were compared in slices from naive and inflamed male and female Sprague Dawley rats. Complete Freund's Adjuvant (CFA) injections into the hindpaw induced persistent inflammation. In naive rats, exogenous cannabinoid agonists robustly reduce both eIPSCs and mIPSCs. After 5–7 d of inflammation, the effects of exogenous cannabinoids are significantly reduced because of CB1R desensitization via GRK2/3, as function is recovered in the presence of the GRK2/3 inhibitor, Compound 101 (Cmp101). Inhibition of GABA release by presynaptic μ-opioid receptors in the vlPAG does not desensitize with persistent inflammation. Unexpectedly, while CB1R desensitization significantly reduces the inhibition produced by exogenous agonists, depolarization-induced suppression of inhibition protocols that promote 2-arachidonoylglycerol (2-AG) synthesis exhibit prolonged CB1R activation after inflammation. 2-AG tone is detected in slices from CFA-treated rats when GRK2/3 is blocked, suggesting an increase in 2-AG synthesis after persistent inflammation. Inhibiting 2-AG degradation with the monoacylglycerol lipase (MAGL) inhibitor JZL184 during inflammation results in the desensitization of CB1Rs by endocannabinoids that is reversed with Cmp101. Collectively, these data indicate that persistent inflammation primes CB1Rs for desensitization, and MAGL degradation of 2-AG protects CB1Rs from desensitization in inflamed rats. These adaptations with inflammation have important implications for the development of cannabinoid-based pain therapeutics targeting MAGL and CB1Rs.SIGNIFICANCE STATEMENTPresynaptic G-protein-coupled receptors are resistant to desensitization. Here we find that persistent inflammation increases endocannabinoid levels, priming presynaptic cannabinoid 1 receptors for desensitization on subsequent addition of exogenous agonists. Despite the reduced efficacy of exogenous agonists, endocannabinoids have prolonged efficacy after persistent inflammation. Endocannabinoids readily induce cannabinoid 1 receptor desensitization if their degradation is blocked, indicating that endocannabinoid concentrations are maintained at subdesensitizing levels and that degradation is critical for maintaining endocannabinoid regulation of presynaptic GABA release in the ventrolateral periaqueductal gray during inflammatory states. These adaptations with inflammation have important implications for the development of cannabinoid-based pain therapies.

AbstractMitochondrial biogenesis is the process of generating new mitochondria to maintain cellular homeostasis. Here, we report that viruses exploit mitochondrial biogenesis to antagonize innate antiviral immunity. We found that nuclear respiratory factor‐1 (NRF1), a vital transcriptional factor involved in nuclear‐mitochondrial interactions, is essential for RNA (VSV) or DNA (HSV‐1) virus‐induced mitochondrial biogenesis. NRF1 deficiency resulted in enhanced innate immunity, a diminished viral load, and morbidity in mice. Mechanistically, the inhibition of NRF1‐mediated mitochondrial biogenesis aggravated virus‐induced mitochondrial damage, promoted the release of mitochondrial DNA (mtDNA), increased the production of mitochondrial reactive oxygen species (mtROS), and activated the innate immune response. Notably, virus‐activated kinase TBK1 phosphorylated NRF1 at Ser318 and thereby triggered the inactivation of the NRF1‐TFAM axis during HSV‐1 infection. A knock‐in (KI) strategy that mimicked TBK1‐NRF1 signaling revealed that interrupting the TBK1‐NRF1 connection ablated mtDNA release and thereby attenuated the HSV‐1‐induced innate antiviral response. Our study reveals a previously unidentified antiviral mechanism that utilizes a NRF1‐mediated negative feedback loop to modulate mitochondrial biogenesis and antagonize innate immune response.
Textual Concepts and Textological Practices in Hungarian Folkloristics
Authors: Domokos Mariann 
Published: July 2023

AbstractFocusing on the concept of ‘folklore text,’ the study surveys the textological dilemmas that a researcher faces during the collection, transcription, publication, and interpretation of folk poetry. Behind the development and implementation of strategies for text editing procedures lie complex cultural processes, which can be interpreted within the framework of the given discipline or placed within a broader cultural and technological historical context. The paper examines the methodological history of Hungarian folklore collections not only according to the theoretical concepts that define the research subject and research aspects but also based on the objective, technological conditions of the collection. The author proposes a folklore textological approach to the publication of texts that is much more conscious of the historicity and origin of folklore texts and considers their own philological-textological tradition. A new, process-based, and transcriber-centered concept of text would provide an intriguing direction for solving numerous folklore textological problems, which might show the role collectors and transcribers play in the creation of a text in a sharper and more nuanced light. The findings of the study are based on investigations carried out in the field of historical folklore text research, primarily on the examination of the methodological history of the collection and transcription of folktales; with certain restrictions, their applicability might be extended in terms of subject matter (to other genres) and time (even to the latest folklore phenomena arising in the digital medium), and they may also provide useful perspectives for representatives of other disciplines that study orality.

Published: July 2023

Many machining processes would not be possible without the presence of cutting oils. There are many diffe­rent types of cutting oils on the market today, each with different properties. The difference of oils is manifested in many parameters such as viscosity, combustion temperature, recyclability, pollution tendency, stability, price, etc. Choosing the best oil is a difficult and tedious task for customers. In this work, we present the results of a study on the selection of cutting oil using multi­criteria decision­making (MCDM) methods. The selection of the best oil is made on the basis of ranking of seven different types. Two MCDM methods used in this study are Proximity Indexed Value (PIV) and Collaborative Unbiased Rank List Integration (CURLI). This two methods have been used to rank cutting oils. These are two methods with completely different characteristics. When using the PIV method, it is necessary to standardize the data and determine the weights for the criteria. Meanwhile, if using the CURLI method, these two tasks are not needed. In addition, three different weight methods were also used to calculate the weights for the criteria including EQUAL, Rank Order Centroid weight (ROC weight) and Rank Sum weight (RS weight). These three methods have been used to determine the weights for the criteria of cutting oil. The PIV method was used three times corresponding to three different weight methods. The results showed that out of the four ranking results (three using the PIV method and one using the CURLI method), the same best oil was unani­mously identified. It is recommended that the CURLI method should be used if weighting of criteria and data normalization are not desired

Welding and joining of brass CuZn30-aluminum AA1100 were obtained using micro two-stage refilled friction stir spot welding (mTS-RFSSW), which was carried out to eliminate the holes formed by the micro friction stir spot welding (mFSSW) process. The mTS-RFSSW process begins with the mFSSW welding process using tools with a pin inner diameter of 2.69 mm, pin outer diameter 1.811 mm and shoulder diameter of 4.954 mm, followed by a second stage process called mTS-RFSSW, which is a hole closing process using a tool with a pinless tool with shoulder diameter 4.954 mm. This study aimed to determine the effect of the second stage of dwell time on the mechanical properties produced in the mTS-RFSSW welding technique using brass CuZn30 and aluminum AA1100 with a thickness of 0.42 mm. In this study, the variable parameter is the second stage dwell time which varies from 3 s, 4 s, 5 s, and 6 s, respectively. An optical microscope that aims to observe the macrostructure shows that an upward hook is formed in each joining process. Based on the scanning electron micrograph, the resulting formation of different intermetallic compounds (IMC) with varying thicknesses occurs in every variation of dwell time. The high dwell time indicates discontinued IMC, which affects the tensile force. The IMC formed at the interface of brass CuZn30 and aluminum AA1100 is dominated by more than 30 % Cu. The highest hardness value is found in the stir zone because the formation of intermetallic compounds influences refined grains. The highest maximum shear force and cross tensile force was obtained 371.35 N and 54.88 N, respectively, in the dwell time of 3 s. The result of fracture properties after the lap shear test shows the presence of small dimples with microcracks that indicate brittle failure

This paper reports a study of the main key components of influence on the stability of transportation enterprises in the market. A model for evaluating the effectiveness of innovation activity in the transport industry, which takes into account indicators of expenditures on innovations, has been built. It makes it possible to determine the effectiveness of introduced innovations, which indicates the appropriate level of innovation potential and the ways that the enterprise must take to increase it. The main directions of innovative development of transportation enterprises were investigated.
The assessment of the economic stability of transportation enterprises in the market has established that the current state of development of enterprises is characterized by a weak level of their innovative activity.
A systematic approach to the introduction of innovative technologies by a transportation enterprise in the market has been devised. This approach makes it possible to determine the required level of enterprise stability and to form a relationship between the level of innovative technologies and their stages of implementation under conditions of environmental variability. This makes it possible to increase competitive advantages, improve the efficiency of production and economic activity of enterprises.
The practical implementation of the proposed model for evaluating the effectiveness of innovation activity in the transport industry has been carried out, which made it possible to allocate the most important indicators of innovation activity for the enterprise. These include specific efficiency of innovation; unit costs of innovation; innovative potential of the enterprise (defined as the proportion of own innovative developments). According to the study results, it is determined that the specific efficiency of innovations (SEI) exerts the greatest influence, which, with an increase by 1 %, provides an increase in financial stability by 1.48 %
