The aim of the present work is to investigate the effect of post treatment of Polysulfone (PSf) hollow fiber membrane prepared by dry/wet spinning on the characteristics and performance of treated membranes. Also, the effect of coating of selected post-treated hollow fiber (HF) membrane on characteristics and performance is investigated. The Polysulfone hollow fiber membranes were prepared under controlled conditions. The post-treatments of HF membranes included treatment by soaking in magnesium sulphate 0.1%, water at 80 oC, sodium hypochlorite (0.1% ) and ethanol/isopropanol (0.1%). The last post-treated hollow fiber membranes were coated to form a thin polyamide layer via interfacial polymerization at controlled conditions. HF membranes were characterized by SEM, AFM, contact angle, porosity, and mechanical properties. The membrane performance with respect to water permeability under pressure up to 3 bar was investigated. The results of the investigation referred to the merits of each of post-treatment with respect to membrane hydrophobicity, membrane surface roughness and mechanical properties as will as water permeability. Further, the coating of post treated membrane produced membranes with low water permeability which could be suitable for membrane separation applications such as UF and NF. Testing of membrane rejection and water flux for different solutes and different conditions is recommended for future work.

Published: July 2023

The synthetic dimensional provides a powerful platform for us to explore the topological properties of matter. In this paper, we choose two physical dimensions ($k_x$ and $k_y$) and one geometric structure parameter (the height of the air cavity $\delta$) to construct a synthetic space. The simulation results display that the three couples of Weyl points and Fermi arcs appear in the synthetic space. We find that the frequency range of valley chiral edge states can be flexibly regulated by changing the position of boundary truncation of the sonic crystal. Both theoretically and experimentally, we demonstrate that the sonic valley-locked whispering gallery can be realized along the interface between the sonic crystals and hard walls. In the valley-locked whispering gallery, the acoustic waves propagate unidirectionally along the closed channel, with highly scattering efficiency and small diffraction.

Authors: Chen Rongping , Du Wei , Liu Dawei
Published: July 2023

This study aimed to explore changes in the venous return system in patients with Constrictive pericarditis(CP) after pericardial stripping and examine their value in predicting mortality. An 8-year single-center retrospective cohort study including patients with CP after pericardial stripping surgery in Intensive care unit (ICU), Peking Union Medical College Hospital. Hemodynamic parameters were analyzed in 90 patients at 11 time points including before and after surgery and every 4 to 9 hours in the first 48 hours in the ICU (0h, t1-t3, 24h, t4-t6, 48h). Mean systemic filling pressure (Pmsf) and resistance to venous return (RVr) were significantly higher in patients who died (non-survival group) than survivors (P = 0.016 and 0.022, respectively). There was a negative correlation between Pmsf at 24h and lactate clearance rate at 6h, while the difference in Pmsf − central venous pressure (CVP) between 48h and 0h was positively correlated with both total fluid balance at 48h and serum creatinine at the time of transfer out of the ICU. Pmsf at 0h, Pmsf at 24h, Pmsf − CVP at 0h, RVr before surgery, RVr at 24h, APACHE II score, and SOFA score were evaluated as predictors of 28-day mortality. The area under the receiver operating characteristic curve was largest for RVr before surgery (0.771; 95% confidence interval, 0.583–0.958; P = 0.034). Pmsf at 0h, Pmsf at 24h, Pmsf − CVP at 0h, RVr before surgery, and RVr at 24h, respectively, combined with APACHE II and SOFA were significant predictors of 28-day mortality. SOFA combined with RVr before surgery had the best performance (area under the receiver operating characteristic curve, 0.883; 95% confidence interval, 0.758–1.000; P = 0.003). Conclusions: Pmsf, Pmsf − CVP, and RVr can be used as valid indicators for prognostic assessment in patients with constrictive pericarditis after pericardial stripping.
Moral hazard in fossil energy markets delays early adoption of zero-greenhouse gas emitting technologies
Authors: De Weerdt Loïc
Published: July 2023

We use a real option approach to formalize the interaction between long-term climate policies, such as the Inflation Reduction Act, and short-term policies intended to protect consumers from volatile fossil energy prices. Examples of the latter are the US releasing strategic oil reserves to lower gas prices and European countries lowering their VAT on natural gas. We find that those short-term policies, which effectively counter incentives created by long-term climate policies, create a moral hazard in fossil energy markets. This, in turn, causes early adopters of zero-greenhouse gas emitting technologies to delay their investment. Ultimate adopters, however, do not change their investment decision. The result of this asymmetric reaction to policies is an intensified gradient of the adoption curve of technology, which potentially puts pressure on various supply chains, the financial system and ultimately government finances.
Hypergraph network embedding for community detection
Authors: Xiang Nan , You Mingwei , Wang Qilin , Tian Bingdi
Published: July 2023

Using attribute graphs for node embedding to detect community structure has become a popular research topic. However, most of the existing algorithms mainly focus on the network structure and node features, which ignore the higher-order relationships between nodes. In addition, only adopting the original graph structure will suffer from sparsity problems, and will also result in sub-optimal node clustering performance. In this paper, we propose a hypergraph network embedding (HGNE) for community detection to solve the above problems. Firstly, we construct potential connections based on the shared feature information of the nodes. By fusing the original topology with feature-based potential connections, both the explicit and implicit relationships are encoded into the node representations, thus alleviating the sparsity problem. Secondly, for integrating the higher-order relationship, we adopt hypergraph convolution to encode the higher-order correlations. To constrain the quality of the node embedding, the spectral hypergraph embedding loss is utilized. Furthermore, we design a dual-contrast mechanism, which draws similar nodes closer by comparing the representations of different views. This mechanism can efficiently prevent multi-node classes from distorting less-node classes. Finally, the dual-contrast mechanism is jointly optimized with self-training clustering to obtain more robust node representations, thus improving the clustering results. Extensive experiments on five datasets indicate the superiority and effectiveness of HGNE.

Published: July 2023

Textile relics was an important part of Chinese precious cultural heritage, and its washing treatment was the primary work of the restoration, display and storage of textile relics. However, the study on washing treatment of textile relics has always been controversial and major challenge, especially the study of washing method. Therefore, in this paper, washing efficiency, degree of abrasion, tensile strength, appearance morphology, infrared spectrometry and EDS spectra of textile relics treated by different washing methods were analyzed and compared to develop an optimal washing method for textile relics adsorbing composite organic/inorganic stains. Results showed that from the view point of balancing the mechanical properties and abrasion of textile relics, as well as the removal and redeposition of stain, the washing method of ultrasonic was more suitable for silk textile relics adsorbing composite organic/inorganic stains, the composite washing treatment {gently brush + ultrasonic (M5), gently brush + micro-nano bubbles (M6)} was more acceptable for cotton, linen and wool textile relics adsorbing composite organic/inorganic stains. In addition, the experimental results also revealed that the composite washing method was more environmental and energy-saving because of its higher decontamination efficiency, reducing the amount of detergent and reducing the washing time. Consequently, there was a huge potential for the application of the developed-optimal washing method for textile relics adsorbing composite organic/inorganic stains to the actual textile relic cleaning work, due to superior cleaning benefits and minimal damage.

Published: July 2023

Human platelet lysate (PL) and human platelet lysate serum (PLS) are alternatives to fetal bovine serum (FBS) due to their ethical concerns, variability between batches, and their possible introduction of xenogenic contaminants. This study compared the composition and efficacy of PL, PLS and FBS as supplements in the culture and cryopreservation of human dermal fibroblasts, Wharton’s jelly derived mesenchymal stem cells (WJ-MCS), and adipose tissue (AdMSC). Biochemical components, some growth factors and cytokines present in each of them were analyzed, in addition, the cells were cultured in media supplemented with 5% PL, 5% PLS and 10% FBS, and exposed to different freezing and thawing solutions with the supplements under study. Biochemical parameters were found to be similar in PL and PLS compared to FBS, with some differences in fibrinogen and calcium concentration. Growth factors and cytokines were higher in PL and PLS compared to FBS. Cell proliferation and morphology showed no significant differences between the three-culture media. Regarding the cryopreservation and thawing of cells, better results were obtained with PLS and FBS. In conclusion, PL and PLS are an excellent choice to replace the standard supplement of animal origin (FBS) in the media used for the culture and cryopreservation of fibroblasts, WJ-MSC and AdMSC.
Optimal Spacing of Grafted ‘Primo Red’ High Tunnel Tomato
Authors: Reid Judson , Machanoff Cordelia , Tucker Caitlin
Published: July 2023

Grafted and ungrafted ‘Primo Red’ tomato (Solanum lycopersicum) transplants were planted at 16-, 20-, and 24-inch spacing in a commercial high tunnel in central New York, USA, to compare yields. ‘Primo Red’ scions were grafted onto ‘Maxifort’ rootstocks and left to heal in a commercial greenhouse facility. Tomatoes were harvested as they ripened, and the weight and number of fruit per plot was recorded and then calculated out to a per-plant basis. Wider plant spacings resulted in higher yields for both grafted and ungrafted plants. However, economic returns remained highest in the highest density (16 inches in-row) spacing with grafted plants. This indicates that growers may not need to adjust density despite additional foliage from grafted plants. Foliar incidence of Botrytis gray mold (Botrytis cinerea) was not significantly different under spacing or grafting treatments. Grafting resulted in higher yields across all plant spacings compared with ungrafted plants. Commercial growers can use this information to make choices on grafting and spacing in high tunnel tomato.

Published: July 2023

This study examines the factors and issues affecting the adoption of electronic insurance (EI) in the Jordanian insurance sector. The methodology of the study is based on convenience sampling, thus, the sample consists of 175 respondents familiar with E-services, with different backgrounds, professions, businesses, income groups, sectors, and regions. Questionnaires were distributed and disseminated electronically using SurveyMonkey. The study employs both descriptive and ANOVA analyses to analyze the responses. The results show that EI promotes sustainability, reduces costs, saves time and holds some operational benefits beneath. The ANOVA results show that the impact of income and age on sustainability, cost-effectiveness, and operational benefits is significant at least at the 5% significance level. Respondents are also aware that EI may involve issues and challenges related to security and privacy, customer-related issues such as lack of knowledge about repositories, and insurer-related issues such as data shifting. The ANOVA results indicate that gender affects customers’ perceptions of EI adoption regarding customer-related issues; its effect is significant at the 5% level of significance. On the other hand, age and income level are important factors that shape respondents’ perceptions of EI in Jordan. Age is only significant for security-related issues, and income level is a deciding factor in insurer-related issues; their effect is strong and highly significant at the 5% and 1% levels, respectively.

Authors: Fang Ruiyue , Liao Yiqi , Qiu Huishuang , Liu Yuxin , Lin Shiyuan , Chen Hui
Published: July 2023

Introduction:

With the rapid development of nanotechnology, the research and development of nano-drugs have become one of the development directions of drug innovation. The encapsulation of the nanoparticles can change the biological distribution of the drug in vivo and improve the bioavailability of the drug in vivo. Naringenin is poorly soluble in water and has a low bioavailability, thus limiting its clinical application. The main purpose of this study was to develop a nano-sized preparation that could improve the oral bioavailability of naringenin.

Methods:

Chitosan oligosaccharide modified naringenin-loaded bovine serum albumin nanoparticles (BSA-COS@Nar NPs) were prepared by emulsification solvent evaporation and electrostatic interaction. The nanoparticles were characterized by HPLC, laser particle size analyzer, transmission electron microscope and X-ray diffraction analysis. The release in vitro was investigated, and the behavior of nanoparticles in rats was also studied. The caco-2 cell model was established in vitro to investigate the cytotoxicity and cellular uptake of nanoparticles.

Results:

BSA-COS@Nar NPs were successfully prepared, and the first-order release model was confirmed in vitro release. In vivo pharmacokinetic results indicated that the area under the drug concentration-time curve (AUC) of BSA-COS@Nar NPs was 2.37 times more than free naringenin. Cytotoxicity and cellular uptake results showed that BSA-COS@Nar NPs had no significant cytotoxic effect on Caco-2 cells and promoted cellular uptake of the drug.

Conclusion:

BSA-COS@Nar NPs could improve the in vivo bioavailability of naringenin.

Ceny pieczarek w eksporcie z Polski i w eksporcie z Holandii
Authors: Zaremba Łukasz
Published: July 2023

Polska i Holandia są największymi eksporterami pieczarek na rynku Unii Europejskiej, jednak w ostatnich latach znaczenie naszego kraju zwiększa się, a Holandii maleje. Analiza cen eksportowych uzyskiwanych przez oba kraje wykazała, że ceny płacone Holendrom są znacznie bardziej stabilne niż w eksporcie polskim. Przy czym, zwłaszcza w Polsce, sezonowe wahania cen mrożonek są wyższe niż grzybów świeżych. Zgodnie z teorią konwergencji cen i Prawem Jednej Ceny można się spodziewać, że poziomy cen eksportowych Polski i Holandii powinny dążyć do wyrównania. Przeprowadzona analiza nie potwierdziła jednoznacznie tego kierunku zmian. Co więcej w przypadku grzybów mrożonych dochodzi do zwiększenia zróżnicowania cen, czyli do dywergencji.

Application of BIM to Buildings and Structures Life Cycle Management
Authors: Savin M. А. , Belash V. V.
Published: July 2023

Introduction. Information modeling of buildings and structures (BIM) implies comprehensive examination of an object including studying engineering, technological and economic information about a building and all interrelations and 42 dependencies it has [1–2]. Such approach enables considering a building and all things referring to it as a single facility.Information modeling is an important tool to be used at various stages of the project implementation, including the design and construction stage [3]. Information modeling is used at each life cycle stage of a facility, including the investment stage, construction itself, and commissioning, which envisages maintenance of a building and management of the assets. Having the information model at this stage is a great advantage for the company managing a facility, due to reduction of the costs arising from the operational shortcomings. The aim of the research was to develop the facility’s operation stage model in the information environment, as the most expensive stage of a building life cycle and supplement it with the calculation of the need-for-repairs indicators.Materials and Methods. During the research the data-analytical environment “Information and Analytical System for Housing and Communal Services” (IAS ЖКХ) for forecasting the technical state of a constructed facility was studied. The method of creating the three models of a multi-storey residential building's operation stage at the pre-investment period was applied: a building undergoing natural depreciation; repairs of the main structural elements directly affecting the existence and functioning of a facility are carried out; regular repairs of all elements are performed.Results. Following the carried-out calculations, a rational model of building operation was approved, based on the period of efficient operation and the cost of repairs during this period.Discussion and Conclusions. The method of the constructed facility operation stage modeling allows examining various scenarios of the building life cycle after its construction and evaluating the relevance of one or another type of operation of a particular facility.
Growing the Forests on Agricultural Land in Russia: Legislative Novelties and Implementation Thereof
Authors: Rodina M. E. , Zakalyuzhnaya N. V.
Published: July 2023

Introduction. For a long time the application of the extensive land and forest management at the abandoned agricultural land had no respective legislative framework, that would regulate forests growing. The proprietors, who were in despair due to the excessive fines imposed on them for not using the agricultural land, had been burning up the forests on their lands causing considerable damage to themselves, society, the state and nature. In Russia, the area of the abandoned agricultural land suitable for forestry is about 76 million hectares. In 2020 two extremely important regulatory legal documents concerning the forests located on the agricultural land not used in compliance with its intended purpose were adopted – the Russian Federation Government Decree No 1509 of September 21, 2020 (hereinafter – Decree No 1509) and the Russian Federation Government Decree No 1482. The business entities (including the proprietors and forest managers) interested in development of this sector have noted the positive dynamics in the legislation development because of the profound opportunities opened for forests multiplication –– there appeared the opportunities for forest farming and growing the forests on the abandoned agricultural land, setting-up the nursery forests, developing the rural territories, particularly in the Non-Black-Soil zone, all of these can benefit the Russian forests stock, preserve biodiversity and, not the least, improve the overall ecological and climate situation in the country and in the world. By the beginning of 2023, this sector of legal relationships has been significantly amended by the legislators, however it should be noted, that the legal regulation and settlement of many issues in this sector still remain difficult. The aim of the present research is to distinguish the problematic issues in development of the Russian Federation agroforestry legislation and implementation of the Russian Federation Government Decree No 1509 of September 21, 2020.

Materials and Methods. In the article, the issue of growing the forests on agricultural land was analysed. The general scientific and specific scientific methods were used in the research. The methodology of the study was based on the dialectical method, as well as on the legalistic, comparative-legal, system-structural kinds of analysis.

Results. It was revealed, that the formidable administrative and regulatory barriers have been set forth the agroforestry evolvement and this sector of the legislation development needs serious reassessment. Urgent steps must be taken to identify all the gaps and shortcomings and to rectify the situation.

Discussion and Conclusions. The problems caused by adding the numerous amendments to the Decree № 1509, complicating the forests growing on agricultural land, have been revealed. The transit to the intensive management of forests and removal of bureaucratic barriers in development of the agroforestry are deemed necessary.

These interactions can occur through a variety of mechanisms, including hydrogen bonding, ionic interactions, and hydrophobic interactions. Changes in protein-protein interactions can alter the normal function of the cell and lead to various diseases. Understanding protein-protein interactions is important for the development of therapeutic approaches targeting these interactions for the treatment of diseases. In this article, I will discuss the role of protein-protein interactions in normal cellular function, the consequences of changes in these interactions, and the importance and significance of understanding these interactions by using the example of dynein-dynactin. Keywords: protein-protein interactions, dynein, dynactin, dysregulation, cargo transport "

In any society, change and political renewal are more than necessary for a good and healthy governance. However, political alternation remains rare in Africa, particularly in French-speaking countries, fact that turned this region, at the beginning of the 2000s, into one of old, authoritarian or semi-democratic regimes not willing to give up the power. This article will focus on the types of actions (coups, revolutions, riots) that have challenged these regimes since the independence of the countries until now. We will analyze the context in which these actions emerged and the way in which they are more or less skillfully managed by the regimes.
THE RUSSIAN IDEA AND THE IDEOLOGY OF RUSSIAN GREAT-POWER CHAUVINISM AND IMPERIALISM
Authors: MIRON Ioana-Mădălina
Published: July 2023

The paper analyses the concept of Russian Idea used by Russian nationalists. A concept that is at the core of the identity of the Russian people. Accordingly, the analysis is based on a theoretical framework that draws attention to the controversial concept of the Russian idea that is reviewed considering changes in the history of the Russian state. Whether formulated by church hierarchs, statesmen, philosophers, ethnologists, or contemporary politicians, various stages in its conceptualization have helped build patriotism in the country. Moreover, in addition to the theoretical framework, the paper focuses on a case study: the February Revolution, known as the February Bourgeois Democratic Revolution or the March Revolution (8-16 March 1917).
SANDINISTA REVOLUTION: A POSTCOLONIAL APPROACH TO USA INTERVENTIONISM
Authors: BONTEA George Horațiu
Published: July 2023

The Sandinista Revolution was a watershed moment in Nicaraguan history that forever altered the course of the country's history. First, it dismantled the Somoza family's dynasty, which had ruled for 43 years, not all of them consecutively, and established a political system dependent on their despotic regime. Second, and more significantly for international relations, the Sadinistas' denunciation of the neo-colonialism committed by the leader of the western democracies was a direct attack on US interventionism in Central America. Unfortunately, it was also the point at which the FSLN established its roots in Nicaraguan society and transitioned from a socialist movement to an authoritarian regime under Daniel Ortega. In order to analyse these evolutions of events I propose a postcolonial theoretical approach. The fact that postcolonialism is a relatively new addition to the international relations theory that first appeared in literature is one of the primary justifications for why this theoretical approach relies on information from native authors. This theory mainly focuses on the former colonies and criticises how the colonial past and present interactions with the former colonists have an impact on how those colonies have developed. I will examine the key ideas of these approaches in the international arena with respect to the particular case of the Sandinista Revolution in Nicaragua.

Introduction. At the initial stages of designing snow blower feeders, it is necessary to have relatively simple ratios on the basis of which one can judge their efficiency and their potential. The presence of such indicators makes it possible to reasonably choose the design scheme, geometric and kinematic parameters of the working bodies of rotary snowplows. The solution of such problems, in turn, can significantly reduce the time for designing machines and their working bodies. Thus, the main goal of this study is to assess the possibility of substantiating the effectiveness of design solutions for snow blowers in the early stages of design. Methods and materials. To achieve this goal, such tasks as the substantiation of the indicators on the basis of which the effectiveness will be assessed, description of the mechanism for obtaining their theoretical values were solved. Results. As a result of the research, analytical expressions were obtained for the volumes of snow mass cut by horizontal and vertical cutters of the rotary snowplow feeder. The time of transporting the cut snow mass has been estimated. The degree of influence of a number of design and technological parameters on the size of the cut snow mass and the time of its transportation is shown. Discussion and conclusion. The equations for the lengths of the trajectories of motion of an arbitrary point of the cutter of the feeder of a rotary snowplow are obtained for its vertical and horizontal arrangement. The equations make it possible to determine the duration of the interaction between the transported snow mass and the working equipment from the moment of its capture to the moment of its unloading. As a result of the research, the range of values was determined, in which the length of the cutting path of the snow mass for a horizontal cutter is less than the length of the cutting path for a vertical cutter.
Turn height calculation for spiral blade
Authors: Nikolayev V. A.
Published: July 2023

Introduction. The problem of accelerating and reducing the cost of road construction without reducing their quality can be solved by creating a complex of continuous units. The units, following each other, carry out the whole range of works aimed at the construction of roads. One of the elements of the continuous unit that forms the cuvette is a direct-flow rotary ripper. It was revealed that for excavation near the axis of rotation of the rotor of a direct-flow rotary ripper, a small rotor with a higher angular velocity should be installed, coaxially with a large rotor. The small rotor contains: a small rotor tip with spiral blades, two teeth and two knives. One of the elements of the small rotor is a spiral blade. The interaction with the soil of spiral blades has not been sufficiently studied. The method of research. The interaction with the ground of the tip of a small rotor with spiral blades is considered. The angles of inclination of the first and second turns of the spiral are determined by the construction of the scan. The following assumptions are made: the ratio of the forces acting on the part of the cone with the spiral to the part of the cone without the spiral is equal to the ratio of the lengths of the cones forming these parts; The spiral blade does not slow down the unit and does not accelerate it, that is, the sum of the forces that counteract the introduction of the cone into the ground balances the forces that introduce the cone into the ground. The sum of the conditional normal reactions of the cone to the impact of the soil is equal to the product of the resistivity of the soil and the surface area of the cone and the coefficient that takes into account the increase in the resistivity of the soil as it is compacted by the cone.Results. On the basis of the methodology, calculations and constructions were made. The area of the front surface of the turn of the spiral blade is approximately equal to the product of the height of the turn and the length of its midline. By construction, the length of the midline of the turns was revealed. The dependences of the length of the spiral on the height of the turn of the spiral blade are shown in the figures. The limits of the angles of inclination of the base of the first and second turns of the spiral blade are established. The height of the turn blade is determined. Conclusion. The angles of inclination of the first and second turns of the spiral are determined by constructing the scan. By constructing projections on the transverse-vertical plane, the lengths of the middle lines of the spiral blade spins are determined. Based on the calculations, taking into account wear during operation and distortion of the projection of the spiral on the transverse-vertical plane, the height of the spiral blade is 10 mm.

Published: July 2023

The purpose of this study was to examine from the perspective of movement what the practices experienced by the actors of the 2019 National Nu-ri Curriculum are. In order to achieve the purpose, this study takes the form of Arts-based research method. The pieces of art are ‘in-depth interview based on art’, ‘a journey with a camera’, and ‘artistic (text) writing of a researcher’. First, in the art-based in-depth interview, a total of 7 early childhood educators located in different networks participated. In a class in which three of the early childhood teachers who participated in the interview were employed, a total of 16 observations were made in each class for about three months. For the collected data, an data analysis was conducted that crossed the boundary between data collection and analysis. The results were as stated below. This study examined that the implementation of the early childhood curriculum operates onto-epistemologically as a learning movement in which teachers, children, and matter interfere with each other. Furthermore, It was an ethical movement conducted in a relationship within a world without the essence of learning. This study was that it considers that the implementation of the early childhood education curriculums unfolds through relationships, entanglement, and interference, and suggests that it needs attention to further expand its vitality.
