A numerical oxidation model for SiC‐coated thermal protection systems in hypersonic applications

AbstractSilicon carbide (SiC) is a widely used component for thermal protection system (TPS) design. This material is often used either as a coating layer to protect beneath carbon‐based material against oxidation or as a ceramic matrix for composite materials used in the hypersonic leading edges. A numerical equilibrium model for SiC‐coated material ablation is developed in this study to compute the material response of coated TPS in hypersonic relevant aerothermal environment. The developed model is based on an equilibrium approach similar to the carbon graphite oxidation framework for ablative charring materials. The equilibrium wall composition is calculated based on the minimization of the Gibbs free energy. The proposed method can capture numerically the transition from passive to active oxidation while maintaining a low computational cost and good numerical stability. Implementation of the model in the Porous Material Analysis Toolbox based on OpenFOAM code permits to compare against previous literature test cases. By comparing the surface temperature obtained from the model with the experimental data, it is observed that the numerical model gives a good estimation providing accurate surface temperature prediction.

КОМПЛЕКСНАЯ ИНФОЛОГИЧЕСКАЯ МОДЕЛЬ ОБЪЕКТОВ ЗАЩИТЫ КОНФИДЕНЦИАЛЬНОЙ ИНФОРМАЦИИ

The problem of harmonization of approaches to the definition of information security objects is becoming increasingly relevant due to the growth of information arrays, the complexity of information technologies, technical and cryptographic means of information protection, and the increasing number of computer attacks, including on critical information infrastructure. Historically, the concept of objects of protection in Russia is associated with the requirements of state regulators, so it has different interpretations. The purpose of the study is to develop an infological model of information security objects. The goal of infological modeling may be to provide the most natural ways for a person to collect and present information about objects of protection for its consideration when creating protection systems and storing in a database. The author based on the analysis of the requirements of the main regulators of the Federal service according to the technical and export control of Russia and the Federal security service of Russia and the modeling method, an infological model of information security objects has been developed. This model is most consistent with the concept of object-oriented design, which is the basis for the development of complex software systems, the development of technology for designing databases of information security objects based on the ER-model. The entity-relationship model (ER-model) has several basic concepts, from which more complex objects are built according to predefined rules.

Research on the Protection System for Smart Grid Based on Phasor Information at Circuit Breakers

A smart grid protection system based on phasor information at circuit breakers is proposed in this paper. Phasor data for fault diagnosis is obtained from phasor measurement units or intelligent electronic devices installed near circuit breakers, without the need for additional measurement equipment. When a fault occurs, the protection system first locates the core protection circuit breaker closest to the fault point. It then identifies the faulty component by analyzing the current phasor differences between this breaker and adjacent ones. This scheme offers high computational efficiency, enabling rapid identification of faulty equipment and its precise location. The proposed protection system structure can be divided into two types: centralized and decentralized, and the most suitable scheme should be selected based on the actual situation. Finally, the feasibility of the proposed scheme was verified through the IEEE 39-bus system and a simulated actual area power grid model, demonstrating its applicability to practical smart grid scenarios. The simulation network validates the implementation method of the proposed protection strategy.

Control of a phytopathogenic infection in an apple orchard in the forest-steppe of Samara Oblast

The study evaluates a protection system by selecting and alternating fungicides having different mechanisms of action to exclude the emergence of resistant populations of apple tree pathogens. The experiments were started at Koshelevsky Posad LLC (Syzransky District, Samara Oblast) in 2022-2023. The orchard was planted in 2013-2014, with trees arranged in a 3.5×1.5 m grid; the 62-396 rootstock was used. The biological effectiveness of fungicide protection against apple scab (Venturia inaequalis (Cooke) Wint.) and fruit rot (Monilia fructigena Pers.) was analyzed using ‘Berkutovskoye,’ ‘Kulikovskoye,’ ‘Kuibyshevskoye,’ ‘Lobo,’ and ‘Northern Sinap’ varieties. The protection system including contact and systemic agents having different mechanisms of action was developed according to the FRAC diagram for assessing the combined risk of fungicide resistance developing in phytopathogens, which takes into account the adaptation rate of organisms (emergence of new resistant types) to changing environmental conditions. An analysis of the correlation between the growth rate of apple-specific phytopathogens and weather conditions shows no significant relationship (0.032-0.245). In these studies, the anthropogenic factor-chemical treatment with fungicides – had a predominant effect on the development of scab and monilia in apple orchards along with weather factors. The yield of marketable apples in the experimental quarter of the orchard differed insignificantly from year to year. In 2023, the yield was lower; however, this fact can be probably attributed to the return of late frosts during apple blossom in Samara Oblast. Noteworthy is that for the ‘Berkutovskoye’ and ‘Lobo’ varieties, unmarketable apples did not exceed 5 and 12 %, respectively, in the studied quarter of the orchard. The protection system using fungicides (GC Shans) helped to optimize the phytosanitary condition of the orchard, thus reducing the amount of fallen fruit and providing a stable harvest of marketable apples.

Institutional fragmentation in United States protected area agencies and its impact on budget processes

PurposeProtected areas, lands and seas set aside for nature conservation, are the main tool for governments to conserve biodiversity. The complexity of government processes, however, can lead to fragmentation in protected area systems. Institutional fragmentation can preclude central coordination and undermine funding and performance. Here, we examine the impact of institutional fragmentation on budgets for protected area agencies in the United States, an important actor in the global conservation movement.Design/methodology/approachThis article uses visual text and network analysis with agency budget documents to examine linkages between agencies. These findings are triangulated with semi-structured interviews analyzed with axial coding to develop a framework for the budget process and its outcomes in US protected area agencies.FindingsThe visual text analysis demonstrates varying levels of coordination between agencies. The conceptual framework shows that five factors - mismatches within agencies, the influence of the Presidential administration, the power of Congress as the appropriator of funds, external forces that influence Congress, and a lack of accountability in allocations – lead to institutional fragmentation and “disparate nature enclaves”.Research limitations/implicationsInterview findings are derived from a non-representative population, and thus should not be generalized for all agencies or budget systems.Practical implicationsUnderstanding the factors influencing agency budget proposals will inform policy to make budgeting more effective for U.S. and other national protected area systems.Originality/valueFew studies have conducted qualitative analyses of federal agencies and their budgets, particularly for federal protected areas.

First measurements of wind-turbine perturbations of fair-weather electric fields

Wind turbines have been shown to develop corona at blade tips due to the presence of the fair-weather electric field, but up to now there have been no published investigations of how the presence of a wind turbine perturbs the fair-weather field as measured on the ground near the turbine. Such data may be useful to evaluate the integrity of turbine lightning protection systems. We present the first such published measurements in this paper. Our model predicts measurable periodic variations, and our experimental measurements show a peak-to-peak perturbation up to about 7 V m−1 in a nominal 100 V m−1 fair-weather field as measured on the ground under the moving turbine's blades. Smaller perturbations are detectable at greater distances.

Reproductive Behavior of Adolescent Girls: Analysis of Risk Factors, Prospects of Prevention and Education

INTRODUCTION: Caring of reproductive health of children and adolescents in the society, especially of adolescent girls as a group most vulnerable to risks in the reproductive sphere, continues to be of high importance. The studies confirm that education and awareness about reproductive health can reduce the probability of problems occurring. The existing legal regulations emphasize the importance of providing accurate and timely information of reproductive health. AIM: Scientific justification of the strategy of forming safe reproductive behavior of adolescent girls on the basis of the peculiarities of their current reproductive behavior taking into account the opinion of specialists in the fields of education and healthcare. MATERIALS AND METHODS: To assess the peculiarities of reproductive behavior of adolescent girls, an anonymous questionnaire survey of 400 adolescent girls was conducted. To determine the expectations of the participants of the sex education process, as well as the main directions of preventive work and education, a survey of 400 parents of adolescent girls, 86 pediatricians, 34 obstetricians-gynecologists and 420 teachers was conducted. For all groups of participants, author’s questionnaires were developed. RESULTS: The reproductive behavior of adolescent girls living in the territory of the Novosibirsk region, is characterized by early start of sex life (15.90 ± 0.14 years), promiscuity (1.70 ± 1.10 partners), refusal to use effective means of contraception. Parents of adolescent girls emphasize the leading role of the family in sex education, suggesting participation of doctors and teachers in the process, but remain dissatisfied with the intensity of preventive measures. A similar problem is emphasized by specialists in the healthcare and education systems who indicate the possibility of conducting preventive work with adolescent girls remotely. In the opinion of pediatricians and obstetricians-gynecologists, providing preventive information on the reproductive health and behavior, will not only create safe reproductive behavior for modern adolescents, but is also an effective strategy of improving the system of reproductive health protection. CONCLUSION: The study identified features of the reproductive behavior of adolescent girls that characterize it as risky. The results emphasize the need for an integrated approach to assessing and maintaining the health of adolescent girls, and also focus attention on the importance of educational work in this age group. The study serves as a basis for further preventive strategies in the field of reproductive health and education.

Heterogeneous Social Network Location Aware Multi Party Data Protection and Privacy System

Social networks are large online communities that allow users to interact and share information. They can be used to connect with friends, family, or potential romantic partners, build a business, or even find a job. The evolution of social media has led to a trend of posting daily photos on online Social Network Platforms (SNPs). The privacy of online photos is often protected carefully by security mechanisms. However, these mechanisms will lose effectiveness when someone spreads the photos to other platforms. This project proposes a blockchain based secure photo sharing framework that provides powerful dissemination control for heterogeneous social network photo sharing. In contrast to security mechanisms running separately in centralized servers that do not trust each other, this framework achieves consistent consensus on photo dissemination control through carefully designed smart contract-based protocols

Heat transfer enhancement mechanics of different micro-disturbing structures for transcritical hydrocarbon fuel using 3-D secondary flow intensity analysis

Heat transfer enhancement based upon micro-disturbing structures becomes increasingly important for thermal protection of air-breathing propulsion systems. To explore the influence mechanism of different structures on heat transfer in regenerative cooling channels of scramjet engines, flow structures and heat transfer of supercritical-pressure n-Decane in mini-channels with dimple and micro-rib arrays are numerically investigated. Results indicate effective heat transfer enhancement inside the channels depends more on efficient transverse turbulence disturbance rather than longitudinal or perpendicular turbulence disturbance. Severe thermal stratification generates strong shear layers in channels, where transverse secondary flows bring much intenser flow mixing than longitudinal secondary flows, especially in transcritical temperature region where the best heat transfer enhancement is obtained. With same characteristic dimensions, longitudinal micro-disturbing structures like dimples have lower flow resistance, but transverse micro-disturbing structures like micro-ribs achieve stronger heat transfer enhancement. Besides, the performance of micro-ribs is much more sensitive to the dimensional change. Therefore, micro-ribs have larger working excursion for enhancing performance factor than dimples. With optimal structure parameters: hr = e = 0.3 mm, pr = 3 mm, hd = 0.225 mm, dd = 1.5 mm, overall performance factor in micro-ribbed channel is 1.14 times of that in dimpled channel. Those conclusions provide effective support for optimization design for the regenerative cooling structures.

Improving the non-structural preparedness of the selected hospital based on the FOCUS-PDCA1 model: action research

IntroductionWith the intensification of the country’s development process, the expansion of cities and population, and the inclusion of Iran in the accident-prone category, reducing the vulnerability of non-structures has received more attention from the organizations involved. In addition to damage to communities and infrastructure, accidents can affect hospitals and their non-organizational components. Hospitals, as the front line of providing medical services after accidents, must maintain their stability, ensure the safety of their patients and employees, and continue to operate without interruption as in normal conditions. Therefore, it is necessary to evaluate the non-structural safety and their preparedness to ensure they can perform acceptable in critical conditions.MethodsThis applied research was conducted in 2023 (September to December) using the participatory action research method in all selected hospital departments. The level of non-structural preparedness of the hospital was checked using the valid “Hospital Safety Index” questionnaire and the non-structural weaknesses of the hospital were identified. Then, in action research using the FOCUS-PDCA model, a program was implemented to improve the non-structural preparedness of different departments of hospitals in the face of accidents and disasters. The non-structural readiness level of the hospital was compared before and after the implementation of the change.ResultsBased on the evaluation conducted in the present study, the lowest level of safety was observed in the water supply system, office furniture and appliances, and fuel storage. The waste management systems, the fire protection system, and the long-distance communication systems were at a desirable performance level. Although in the evaluation before the change, the overall score of the hospital was 71.01%, and it had a desirable performance level in non-structural factors, in all the involved parts of the hospital, the sensitive, critical, and practical parts in the operation of the hospital had an average and sometimes low safety level. According to the obtained safety score, the safety level of the selected hospital before the change was 7 out of 10 (level seven of safety evaluation = medium). After the change and corrective measures, the non-structural safety assessment score was 76.93, and the hospital’s safety level was raised by one step to 8 out of 10 (8th level of safety assessment = relatively favorable).ConclusionThe present study showed that the application of Total Quality Management (TQM), primarily its application tool FOCUS-PDCA, is efficient and helpful in improving the non-structural preparedness of hospitals. Using action research in the health field in accidents and disasters can open blind knots in different dimensions of preparedness (structural, non-structural, and functional).

Astragalus mongholicus Bunge extract improves ulcerative colitis by promoting PLCB2 to inhibit colonic epithelial cell pyroptosis

Ethnopharmacological relevanceAstragalus mongholicus Bunge (AM) and its active ingredients are mainly used for anti-inflammatory, antiviral, antioxidant, immune regulation, cardiovascular and nervous system protection, anti-cancer, anti-tumor and so on. Aim of the studyTo explore the Astragalus mongholicus Bunge extract pharmacological mechanisms and biology processes which improves ulcerative colitis (UC). Materials and methodsDextran sulfate sodium (DSS)-induced UC models in C57BL/6 mice were established, and the mice were treated with Astragalus mongholicus Bunge extract or salazosulfapyridine (SASP). DSS-induced mice- and human-derived colonic epithelial cell lines were used to reveal the inflammatory environment of UC. After treatment with Astragalus mongholicus Bunge extract, the expression of phospholipase C-β 2 (PLCB2) in the cells was detected by quantitative real-time PCR (qRT-PCR), and cell proliferative activity was detected by cell counting kit 8 (CCK-8) assay. Finally, the levels of pyroptosis-related inflammatory factors in cell culture supernatants was detected by ELISA. ResultsTreatment of UC mice with Astragalus mongholicus Bunge extract do significantly improved DAI scores and histopathological damage scores, and decreased the levels of Eotaxin, GCSF, KC, MCP-1, TNF-α, and IL-6. Besides, Astragalus mongholicus Bunge extract inhibited the expression of nucleotide-binding oligomerization segment-like receptor family 3 (NLRP3), cleaved Caspase-1, and GSDMD-N in the colonic tissues, and reduced the levels of inflammation-related factors IL-1β and IL-18 in serum and tissues. In vitro, Astragalus mongholicus Bunge extract partially reversed the DSS-induced reduction of PLCB2 expression in CP-M030 and NCM460, promoted cell proliferative activity, and reduced the levels of IL-1β and IL-18. ConclusionsIn DDS-induced UC mice, Astragalus mongholicus Bunge extract improves ulcerative colitis by inhibiting colonic epithelial cell pyroptosis through PLCB2 promotion.

Private Enforcement Under the Digital Markets Act: Rights and Remedies Revisited

The Digital Markets Act (DMA) is a new instrument of EU competition policy. It has been pointed out that although the DMA does not include any provisions on private enforcement, there should still be room for private enforcement of rights under the DMA. However, it has not been properly scrutinised to what extent the provisions of the DMA are suitable for such private enforcement. This article contributes to the literature by addressing this deficit and explaining the interwoven aspects of EU law and national law upon which private enforcement of the DMA will rely. The analysis is carried out in two main tiers. First, the core substantive provisions of the DMA are analysed. It is concluded in this stage that there are some rules in the DMA which may trigger private law sanctions when breached. Second, the system of judicial protection of rights conferred on individuals under EU law is explained and applied to the DMA. In this regard, it is concluded that it would be appropriate to extend any private law remedies that are available to claimants who have been victims of an infringement of Article 101 or 102 TFEU to claimants who have been victims of an infringement of protective provisions in the DMA.
