The impact of freeze-dried Baiyedancong-Oolong tea aqueous extract containing bioactive compounds on the activities of CYP450 enzymes, the transport capabilities of P-gp and OATs, and transcription levels in mice.

In this study, (-)-epigallocatechin gallate (EGCG) and caffeine extracted from freeze-dried autumn Baiyedancong Oolong tea (FBOT) were orally administered to mice for 7 consecutive days to explore the effects of BOT and its bioactive compounds on the activities and transcription levels of CYP450 enzymes, intestinal effluence transporter P-gp, and renal ingestion Organic Anion Transporters (OATs). Concurrently, EGCG and caffeine enhanced the activities of CYP3A, CYP2E1, and CYP2C37 in the liver of mice, while impairing the transport capabilities of P-gp and OATs. Reduced levels of MDR1 encoding P-gp transcription in the small intestine and renal OAT1 and OAT3 revealed that transcription was involved in the regulation of CYP450, P-gp, and OATs. The reduced transcription level of liver CYP2E1 suggested that CYP2E1 activity may have been elevated due to alternative mechanisms, but not through transcription. The absorption, metabolism, and excretion of drugs may be influenced by the daily consumption or high-dose administration of BOT and its related products, in which EGCG and caffeine may make great contributions.

Moscow State Conference in the crosshairs of confrontation

The author focuses on the initiative minority, which, in fact, was mobilized during the days of the Moscow State Conference. The article notes the great contribution of A.B. Nikolaev in the study of this significant and often ignored political forum in historiography. Thanks to this monograph, it is possible to trace the motivation of key political forces, as well as their leaders. They all had to adapt to the conditions of revolutionary Russia in one way or another. However, in most cases these attempts were unsuccessful, as was clearly demonstrated in August 1917.

Application of major ions and Sr isotopes to indicate the evolution of river water and shallow groundwater chemistry in a typical endorheic watershed, northwestern China

Studying the hydrochemical evolution of river water and groundwater is vital for comprehending complex regional hydrological cycles and managing water resources. An investigation of hydrochemical evolution mechanism of river water and groundwater was executed in an arid and semi-arid endorheic watershed located in the eastern edge of Qaidam Basin, northwest China, by analyzing major ions and strontium isotopic compositions with the combination of hydrogeochemical methods, PMF model and Pearson correlation analysis. From upstream to downstream, the major ions, 87Sr/86Sr values and hydrochemical types of river water and groundwater show spatial variations. Major ions and 87Sr/86Sr analysis reveal that the hydrochmical compositions of river water and groundwater are primarily attributed to silicate weathering, carbonate weathering, evaporite weathering, and agricultural activity. The contribution of four factors affecting the hydrochemical evolution show obvious spatial variations along the flow path. The hydrochemical compositions of river water from the upstream to downstream are mainly contributed by carbonate and silicate weathering as well as weak evaporite weathering (<25%), which are affected by agricultural activity with a great contribution (>25%) in the middle and lower reaches. The contribution to the hydrochemical compositions of groundwater is relatively small (<25%) for carbonate, silicate and evaporite weathering, but great (>25%) for agricultural activity. This study provides implications for understanding the formation and evolution of water and better watershed water management in that typical endorheic watershed basin and even at larger scales.

Back-Side Stress to Ease p-MOSFET Degradation on e-MRAM Chips

Abstract Magnetoresistive random access memory process makes great contribution to threshold voltage deterioration of metal-oxide-silicon field-effect transistors, especially on p-type devices. Herein, a method was proposed to reduce threshold voltage degradation by utilizing back-side stress. Through the deposition of tensile material on the back side, positive charges generated by silicon-hydrogen bond breakage were inhibited, resulting in a potential reduction of threshold voltage shift by up to 20%. In addition, it was found that the method could only relieve silicon-hydrogen bond breakage physically, failing to provide a complete cure. However, it holds significant potential for applications where additional thermal budget is undesired. Furthermore, it was also concluded that the method used in this work was irreversible, with its effect sustained to the chip package phase, and it ensures competitive reliability of the resulting magnetic tunnel junction devices.

Investigation on the microstructural evolution and corrosion behaviors of Zn-microalloyed Al-Cu-Li alloys

Zn microalloying made great contributions to microstructures evolution and performances enhancement. The effects of various contents of Zn on the precipitate microstructure, tensile property and corrosion behavior of Al-3.2Cu-1.5Li alloys with medium Cu/Li mass ratio were examined by tensile testing and corrosion measurement. Experimental results demonstrated that the tensile strength of the Zn microalloyed samples dropped slightly as the Zn content increased due to the number density of precipitates with minor size variation showed a downward trend within the grains. Corrosion testing revealed that the corrosion type of Zn microalloyed samples was primarily localized intragranular corrosion, slight intergranular corrosion and local pitting corrosion was also partially involved. The emergence of Zn element in grain boundary (GB) coarse (T1) phases and the suppressed precipitation of intragranular phases in the alloys with higher content Zn were found to reduce corrosion sensitivity with the increase of Zn content, which was ascribed to the decreased potential difference between the GB and adjacent matrix, and between the GB precipitates and precipitation free zone (PFZ).

Controlling soil erosion and landslides through ecosystem-based adaptation interventions in the hilly landscape of western Rwanda

Ecosystem-based Adaptation interventions such as protective vegetation, soil and water conservation measures and re-vegetation of degraded land have shown promise in reducing soil erosion and landslides occurrence. The western province of Rwanda has experienced destructive natural hazards especially soil erosions, floods and landslides. This study aimed to assess the contribution of Ecosystem-based Adaptation interventions on the reduction of soil erosion and landslides in the hilly landscape of Western Rwanda with a case study of Rubyiro sub-catchment in Rusizi District. Methods used in data collection comprised remote sensing techniques combined with a questionnaire survey to collect perceptions of farmers conducting agricultural activities in the catchment where Rusizi District has implemented Ecosystem-based Adaptation (EbA) interventions. The Revised Universal Soil Loss Equation (RUSLE) model combined with Geographic Information System (GIS) and remote sensing tools were used to assess soil loss pre- and post-EbA interventions. The results of the survey indicated that after four years of EbA interventions, the number of landslide occurrences was reduced at a rate of 62.6 %. The respondents who appreciated forest restoration to minimize landslides were 72.4 %, progressive terraces 26.1 % and bench terraces 1.5 %. The estimated average annual soil losses were 11.9 tons/ha/year, 17.6 tons/ha/year, 10.1 tons/ha/year, 9.3 tons/ha/year in 2017, 2018, 2021 and 2022, respectively. This indicates a reduction of 8.3 tons/ha/year from 2018 to 2022 as opposed to an increase of 5.7 tons/ha/year recorded from 2017 to 2018. Thus, EbA interventions made a great contribution to the reduction of soil erosion and landslides in the Rubyiro sub-catchment, and they can be recommended in other similar hilly landscapes.

Fuzzy implications-based transformation approaches from semi-three-way decision spaces to three-way decision spaces and their applications

Three-way decision spaces, as an important component of three-way decisions, greatly enrich their theoretical development and application prospects. Meanwhile, fuzzy implications, as a vital class of fuzzy logic connectives, have made great contributions to the solution of practical problems, especially complex decision-making problems. This paper considers the collaborative effect of the two, which inject new vitality into the theoretical development and application prospects of fuzzy implications and three-way decision spaces. As a vital component of three-way decision spaces, (semi-)decision evaluation functions have been widely studied based on fuzzy logic connectives and become a research hotspot. Specifically, this paper focuses on fuzzy implications-based transformation approaches from semi-three-way decision spaces to three-way decision spaces and their applications. Firstly, we present some novel fuzzy implications-based transformation approaches from semi-decision evaluation functions to decision evaluation functions, and construction approaches of semi-decision evaluation functions involving the existing semi-decision evaluation functions, fuzzy sets, interval-valued fuzzy sets and fuzzy relations. Secondly, we discuss the relationship between our approaches and the known construction approaches of three-way decision spaces. Notably, our approaches cover all existing approaches except the uninorms-based approaches. Finally, by the experiment results, we obtain our approaches are feasible, effective, superior to the known three-way decision spaces approaches and have good anti-noise ability. And, the parameter ρ of our approaches is also effective and stable.

Phase transition and internal friction behaviors in Mn-doped Co-V-Ga shape memory alloys

Shape memory alloys with a high abundance of mobile interfaces exhibit remarkable internal friction (IF) behaviors, which can be utilized for the reduction of noise and vibration. In this study, we systematically investigate the martensitic transformation and internal friction behaviors in the Mn-doped Co53V35–xGa12Mnx (x = 0 - 10) polycrystalline alloys. Our findings indicate that using Mn to replace V results in decreased transformation temperatures but increased thermal hysteresis. The addition of Mn enhances magnetic exchange interaction, leading to a gradual enhancement in magnetization difference across martensitic transformation, thereby compromising the transformation entropy change and arresting the martensitic transformation. At a frequency of 0.4 Hz, the intensity of transformation IF peak is enhanced from 0.124 to 0.178 with increasing the Mn content from 0 to 4.5 %, as a result of deteriorated geometrical compatibility between austenite and martensite due to the addition of Mn. Furthermore, hydrogenation treatments substantially improve both the peak intensity and frequency dependence of peak position for the relaxation-type IF, demonstrating the great contribution from hydrogen-twin boundary interaction.

Patterns of non‐migratory fish metacommunity from Neotropical floodplains: Local mechanisms, regional scale and hydrological dynamics

AbstractThe spatial distribution of biological communities may be regulated by environmental and spatial processes, and the intensity of these processes depend on the species characteristics, spatial heterogeneity and spatial extent. We investigated the relationship between the non‐migratory fish metacommunity with environmental and spatial variables using the variance partitioning procedure. We used data from lakes of four Neotropical floodplains: Amazon, Araguaia, Pantanal and Paraná. We hypothesised that the processes that drive the spatial distribution of non‐migratory fish in floodplain systems depend on connectivity driven by flood pulse. We predict that spatial variables are less important to explaining the fish community structures during rainy periods when there is no dispersal limitation. In contrast, environmental variables influence these structures during rainy and dry periods. During dry periods, metacommunities depend on species' dispersal abilities, but during rainy and dry periods, spatial distribution depends on the environmental filters selected by each species. For most of the environmental variables, it was possible to observe more similarity in the rainy period. Our results showed different patterns of fish communities for the lakes of the four floodplains systems, which led us to reject our hypothesis. Non‐migratory fish remain in their natal environment and perform only small lateral movements. In this scenario, we found a little influence from spatial variables in both periods and a great contribution of environmental variables for Amazon (16%) and Pantanal (32%) floodplains in structuring fishes' distribution in the rainy period.

Heavy-duty vehicles with solar panels as a regenerative power source

Abstract Road transportation represents more than a third of all CO2-producing sources on Earth, being the main producer of greenhouse gas (GHG) emissions. Nowadays, continuous development of technology has reduced fossil-fuel consumption by integrating clean energy sources as a range extender. Solar energy has the largest potential of all renewable energy sources worldwide. The photovoltaic and energy storage research fields have grown exponentially during the last decade and, forced by the current energy crisis, had a great contribution to the hybrid solar vehicles (HSV) industry. Vehicle Integrated Photovoltaics (VIPV) comply with requirements on vehicles aesthetics, and they convert solar energy into electric energy to supply the low-voltage and high-voltage battery packs onboard HSV. Heavy-load road transportation by commercial vehicles equipped with PV-integrated modules or retrofit installation will contribute to global decarbonization. A study is done on a configuration of a heavy-duty vehicle with its cuboid cargo body covered with solar panels and a regulated driving route during different weather conditions [3]. The energy management system is designed to maximize solar energy conversion in order to reduce fuel consumption and extend the vehicle’s total driving distance.

The Phases Of Showalter’s Feminist Criticism Prefigured In Henrik Ibsen’s A Doll’s House

Elaine Showalter (1941- ) is one of the most influential American literary critics and feminists who influenced feminist literary criticism by developing the concept and practice of gyno-criticism. She published A Literature of Their Own: British Women Novelists From Brontë to Lessing in 1977 and whose expanded edition came out in 1999. By and large this book explicates Showalter’s groundwork to revive the interest in long-forgotten women writers in British literature history. It was a monumental work, indeed a kind of rediscovery, mapping widely rather than mining deeply the territory of women’s writing. In a sense, feminist criticism came of age with this book. Showalter suggests that women themselves were slowly growing aware of their separateness from men and leaving a record of that awareness in their works. It is the growth of a collective selfconsciousness—the history of a distinct literary subculture—that A Literature of Their Own sets out to record. ‘Towards a Feminist Poetics’ (1979) is one of her well known essays that focused on the feminist literary criticism of the literature. In this essay, Showalter has rejected the inevitability of the male theories and male models by tracing the history of women’s literature in the present writing. 'Toward a Feminist Poetics' by Showalter also refers to the three phases of feminist literary criticism. The first phase is the feminine phase where women aimed to compete with male writers, and compared their craft with that of their male contemporaries. The second phase is the feminist phase where the critics focus on the injustices and wrongs done to women in literary texts, and reject the conventional roles of females. Finally, the female phase is independent of the dependency on and obsession with the male literature. It instead aims to focus on creating a female literary tradition that includes women's internal experiences and personal history. This theoretical literary presentation of Showalter can be dramatically viewed in the evolution of character Nora in A Doll’s House by Henrik Ibsen (1828 -1906). Ibsen was a Norwegian playwright and theatre director. He was one of the founders of modernism in theatre and often called “the father of realism” and the most influential playwright of the 19th century. A Doll’s House is a three acts play through which Ibsen challenged the stereotypical representation of women in literature with his female characters and remains a great contribution to feminist literature

LINGUISTIC PERSONALITY AND ITS MANIFESTATION IN SCIENTIFIC LANGUAGE TEXTS (BASED ON THE MATERIAL OF GAISA KHUSAINOV'S WORK)

This article is devoted to the analysis of the linguistic personality traits of one of the most famous scientists of Bashkortostan and a writer who made a great contribution to the development and enrichment of the Bashkir national literature Gaysa Khusainov.

The ways of adapting the working schemes of multifunctional soil-cultivating sowing units.

BACKGROUND:With the development of technology, the use of combined machines and units has become increasingly popular. From the numerous studies that were carried out during the maintenance of machines of this type, it can be seen that the cost of raw materials and finances have been significantly reduced, and a host of other advantages have also been identified. AIMS:The purpose of the research is to find ways to adapt the working schemes of multifunctional tillage sowing units for a more convenient combination of design schemes and parameters of its use. MATERIALS AND METHODS:Engineers use the method of adapting machines by changing working bodies designed in the form of schemes into modules that perform various types of operations based on working conditions. Thanks to this method, sets of individual working bodies and combinations are formed for any kind of conditions (soil, climate, etc.) In addition to the advantages, this system has a number of disadvantages. One of these is that at the manufacturing plants, the modules that are part of the starting base of the unit cannot be 100% adapted to environmental conditions and economic factors of production. In this regard, it becomes problematic to combine structural schemes, select the necessary parameters with minimal losses and adjust the unit to the necessary operating mode, based on the system-structural synthesis of their working scheme. As an object of study, devices and production processes were installed, the main task of which is the implementation of tillage and sowing work. In particular, one can single out oscillatory and mechanical technical processes that determine the behavior of realizing systems and subsystems.The practical value of this study presented in the form: - creation of a special computer scheme which is capable of structuring the analysis and synthesis of the constructive system of the tillage-sowing unit to find the working links for various types of unit functions; - finding methods and improved combinations of working bodies, comparing similar mechanical analogues with the original properties of systems. A lot of research has been carried out in the field of machine combinations. A great contribution to the research was made by the works of M.S. Runcheva, E.I. Lipkovich, A.A. Vilde and other research scientists. RESULTS: When studying the studies of Wilde, who characterized the combined units, as well as the works of Runchev, who determined the generalization of the combined machines, an actual typology of agricultural machines was developed. In this typology, one of the most important characteristics is multifunctionality, which has developed from the need for the versatility of units and the compilation of combinations of several units. The developed technology contains a number of characteristics that are fundamental for the choice of agricultural machines. These are temporal, energy, constructive, spatial characteristics of the technical process. CONCLUSIONS: As a result of the study, it was determined at what speed of the unit the system is balanced.

Facilitators and barriers of midwife-led model of care at public health institutions of dire Dawa city, Eastern Ethiopia, 2022: a qualitative study

BackgroundThe midwife-led model of care is woman-centered and based on the premise that pregnancy and childbirth are normal life events, and the midwife plays a fundamental role in coordinating care for women and linking with other health care professionals as required. Worldwide, this model of care has made a great contribution to the reduction of maternal and child mortality. For example, the global under-5 mortality rate fell from 42 deaths per 1,000 live births in 2015 to 39 in 2018. The neonatal mortality rate fell from 31 deaths per 1,000 live births in 2000 to 18 deaths per 1,000 in 2018. Even if this model of care has a pivotal role in the reduction of maternal and newborn mortality, in recent years it has faced many challenges.ObjectiveTo explore facilitators and barriers to a midwife-led model of care at a public health institution in Dire Dawa, Eastern Ethiopia, in 2021.Methodology: A qualitative approach was conducted at Dire Dawa public health institution from March 1–April 30, 2022. Data was collected using a semi-structured, in-depth interview tool guide, focused group discussions, and key informant interviews. A convenience sampling method was implemented to select study participants, and the data were analyzed thematically using computer-assisted qualitative data analysis software Atlas.ti7. The thematic analysis with an inductive approach goes through six steps: familiarization, coding, generating themes, reviewing themes, defining and naming themes, and writing up.ResultTwo major themes were driven from facilitators of the midwife-led model of care (professional pride and good team spirit), and seven major themes were driven from barriers to the midwife-led model of care (lack of professional development, shortage of resources, unfair risk or hazard payment, limited organizational power of midwives, feeling of demoralization absence of recognition from superiors, lack of work-related security).ConclusionThe midwifery-led model of care is facing considerable challenges, both pertaining to the management of the healthcare service locally and nationally. A multidisciplinary and collaborative effort is needed to solve those challenges.

The Roles of Psychosocial Factors and Nutritional Intervention on Eating Disorders

With a multifaceted and intricate etiology, eating disorders are classified as mental diseases. The etiology of eating disorders includes sociocultural factors such as family and childhood experiences, societal and cultural pressures, imposition of media standards, as well as psychological factors such as low self-esteem and body dissatisfaction, stress, anxiety, mood disorders, trauma, and perfectionism. To provide a nutritional intervention that includes the normalization of eating behavior, it is necessary to understand the psychosocial aspects underlying the illness of individuals with eating disorders. Because a dietitian may be the first person to recognize the symptoms of an individual's eating disorder, which is a psychiatric disorder, or the first healthcare professional to whom a patient applies for this condition, and dietitians are a critical member of the treatment team of these patients. During the planning of nutritional intervention; practices such as defining nutritional problems related to medical or physical condition, evaluating anthropometric measurements and biochemical data, examining behavioral and environmental factors, calculating energy and macronutrient requirements, increasing the amount and variety of foods consumed, and giving recommendations regarding the normal perception of hunger and satiety constitute the basic processes of nutrition intervention planned in line with appropriate weight restoration and health goals. In this process, providing psychosocial support and positive reinforcement by considering the changing needs of the individual may help to increase their commitment to the process. Being in constant cooperation and communication with the healthcare professionals involved in the treatment and the family of the individual during the treatment period constitutes an integral part of a well-managed treatment process. In this respect, the health professionals in the treatment team informing the other members of the team by considering the etiological factors of the eating disorder and providing a joint decision-making environment makes a great contribution to the treatment process.

A novel 4-DOF marine stern bearing support model considering discrete distribution effects

To address the issue of the traditional support model's inability to accurately describe the non-uniform dynamics behavior inside the bearing, this study proposes a novel 4-degree-of-freedom (DOF) bearing support model that incorporates the discrete distribution effects induced by the bi-directional misalignment and bending deformation of the journal. Additionally, a coupling algorithm is designed to study the interaction behaviors between the marine stern bearing lubrication performance and the shaft dynamics. Moreover, a full-size marine shaft alignment test rig for measuring dynamic bearing loads is designed to verify the validity of the present model. On this basis, the effects of different bearing models, rotational speeds, external loads, and bush elastic modulus on the shaft dynamic alignment and the static and dynamic characteristics of the stern bearing are investigated. The experimental results indicate that the 4-DOF model, which takes into account discrete distribution, exhibits a more precise prediction of the alignment characteristics of the shaft system, with a forecast error for the stern bearing load of 1.32%. Heavy loads or low rotational speeds significantly deteriorate the edge-loading effect and increase the stiffness and damping coefficient of the bearings. The bearing lubrication performance directly affects the alignment performance of the shaft system, particularly in low-speed conditions. A softer bush material can increase the minimum oil film thickness, carrying region, and damping coefficient, mitigate the phenomenon of edge-loading, and facilitate the vibration control of the shaft. Research results have made a great contribution to marine shaft alignment optimization and structure design.

Co-Expression Network Analysis and Introgressive Gene Identification for Fiber Length and Strength Reveal Transcriptional Differences in 15 Cotton Chromosome Substitution Segment Lines and Their Upland and Sea Island Parents.

Fiber length (FL) and strength (FS) are the core indicators for evaluating cotton fiber quality. The corresponding stages of fiber elongation and secondary wall thickening are of great significance in determining FL and FS formation, respectively. QTL mapping and high-throughput sequencing technology have been applied to dissect the molecular mechanism of fiber development. In this study, 15 cotton chromosome segment substitution lines (CSSLs) with significant differences in FL and FS, together with their recurrent parental Gossypium hirsutum line CCRI45 and donor parent G. barbadense line Hai1, were chosen to conduct RNA-seq on developing fiber samples at 10 days post anthesis (DPA) and 20 DPA. Differentially expressed genes (DEGs) were obtained via pairwise comparisons among all 24 samples (each one with three biological repeats). A total of 969 DEGs related to FL-high, 1285 DEGs to FS-high, and 997 DEGs to FQ-high were identified. The functional enrichment analyses of them indicated that the GO terms of cell wall structure and ROS, carbohydrate, and phenylpropanoid metabolism were significantly enriched, while the GO terms of glucose and polysaccharide biosynthesis, and brassinosteroid and glycosylphosphatidylinositol metabolism could make great contributions to FL and FS formation, respectively. Weighted gene co-expressed network analyses (WGCNA) were separately conducted for analyzing FL and FS traits, and their corresponding hub DEGs were screened in significantly correlated expression modules, such as EXPA8, XTH, and HMA in the fiber elongation and WRKY, TDT, and RAC-like 2 during secondary wall thickening. An integrated analysis of these hub DEGs with previous QTL identification results successfully identified a total of 33 candidate introgressive DEGs with non-synonymous mutations between the Gh and Gb species. A common DEG encoding receptor-like protein kinase 1 was reported to likely participate in fiber secondary cell thickening regulation by brassionsteroid signaling. Such valuable information was conducive to enlightening the developing mechanism of cotton fiber and also provided an abundant gene pool for further molecular breeding.

Hydrothermal synthesis and characterization of 0D/2D SrMoO4/g-C3N4 composite with direct Z-scheme heterojunction: Efficient photocatalytic Ciprofloxacin degradation

Ciprofloxacin (Cip) is a common pollutant that causes sewage problems, and its effective removal is a great contribution to the clean water environment. Direct Zener-scheme (Z-scheme) heterojunction photocatalyst is a promising design idea for the removal of residual antibiotics in water. The goal of this study is to construct a binary composite photocatalyst with Z-scheme heterojunction to effectively remove residual ciprofloxacin in wastewater. Herein, a direct Z-scheme 0D/2D SrMoO4/g-C3N4 (SMOCN) composite photocatalyst was synthesized by ultrasonic-assisted hydrothermal way and its interior information (chemical structure, micromorphology, and physic-optical property) was detected by various characterization instruments (XRD, FT-IR, EDX, XPS, UV–Vis DRS, and PL). Meanwhile, the photocatalytic activity of all-prepared catalysts were estimated by Cip photodegradation experiments under simulated sunlight (500 W Xenon lamp). Among them, 89.9 % of Cip was broken down by 30SMOCN composite within 180 min at pH 7.0, which respectively reached 2.56 times of bare SMO and 2.03 times of bare CN. Furthermore, 85.2 % of Cip targeted molecule is still removed by SMOCN (excellent stability and recyclability) after five cycle runs. Finally, the reasonableness of SMOCN conforming to the direct Z-scheme mechanism is verified by comparison of optical properties, quenching experiment results and photogenerated carrier migration paths: 1) There is optical complementarity between SMO and CN, which is represented by redshifted absorption edge, narrowed band gap and weaken PL intensity. 2) The key active site on the SMOCN composite surface is photogenerated carriers in Cip photocatalytic degradation, which given full play to the direct synergistic catalytic effect between SMO and CN heterojunction. 3) The direct Z-scheme mechanism preserves the carriers of SMOCN with effective photo-redox function, promotes their separation and prolongs their lifetime.
